Description

Feeding device, feeding control method and system of grinding machine, equipment and medium

Technical Field

The invention relates to the technical field of grinding machines, and particularly provides a feeding device, a grinding machine, a feeding control method of the grinding machine, a feeding control system of the grinding machine, computer equipment and a computer readable storage medium.

Background

A grinding machine is a device for grinding a hard and brittle material. Such as grinding machines, typically include a loading assembly, a feed assembly, and a grinding assembly. For example, the piece of hard and brittle material is taken as a silicon rod, for example, the cut silicon rod is firstly fixed to the feeding assembly, the position and the posture of the cut silicon rod are subjected to certain initial adjustment, and then the silicon rod is conveyed between two chucks of the feeding assembly, for example, the two chucks can be both movable chucks or one chuck is a movable chuck and one chuck is a fixed chuck. The silicon rod is conveyed to the grinding assembly through the axial movement of the silicon rod so as to perform grinding processing including rough grinding and fine grinding on the first group of surfaces to be ground. Then, the silicon rod is rotated to a second group of surfaces to be ground, and on the basis of this, grinding processing including rough grinding and finish grinding is performed on the second group of surfaces to be ground. And repeating the steps until all the surfaces to be ground of the silicon rod are ground according to the set grinding standard.

Still take the piece of hard and brittle material as the silicon rod for example, because the specification of silicon rod is different and the overall dimension of the silicon rod of same specification also differs, therefore when putting the silicon rod on the loading platform, there is certain positional deviation usually between the axis of silicon rod and the axis of two chucks. In addition, because the surface of the silicon rod before grinding is uneven, a certain angle deviation exists between the axis of the silicon rod and the axes of the two chucks. Obviously, the existence of the position deviation and the angle deviation can influence the coaxiality of the two axes, and the coaxiality between the two axes is represented as the feeding precision of the silicon rod on the grinding machine. The failure of any link of the position deviation and the angle deviation can affect the feeding precision of the silicon rod, and the reduction of the feeding precision can be generally represented by the increase of grinding quantity of the silicon rod and the improvement of silicon loss with different degrees, thereby reducing the processing efficiency of a grinding machine and reducing the surface quality of the silicon rod.

Disclosure of Invention

The invention aims to at least partially solve the technical problems, and specifically, any link of the position deviation and the angle deviation is restrained or eliminated, so that the feeding precision of the silicon rod is improved on the basis, and the processing efficiency of a grinding machine and the surface quality of the silicon rod are further improved.

In a first aspect, the present invention provides a feeding device, including: 1) Feeding subassembly, it includes: 11 A lifting assembly including a pallet on which a workpiece to be machined can be placed, the lifting assembly being capable of lifting the workpiece to be machined placed on the pallet in a vertical direction and allowing different parts of the workpiece to be machined to be lifted to different heights; 12 The clamping assembly comprises a clamping first end assembly, a clamping second end assembly and an adjusting assembly arranged on the clamping first end assembly and/or the clamping second end assembly, wherein the adjusting assembly can enable different parts of a workpiece to be processed to be different from the corresponding distance between the clamping first end assembly and/or the clamping second end assembly.

With such a configuration, the loading height of the workpiece to be machined, such as a silicon rod to be ground, can be increased from three dimensions by the loading device.

Compared with the mode of manually participating in directly blanking (bar withdrawing) the to-be-machined part, the invention directly places the to-be-machined part in the feeding device for readjustment, thereby improving the adjustment efficiency. Compared with the mode of adjusting through a (fixed and movable) chuck in the feeding direction, the feeding precision adjustment in four dimensions can be realized through different parts because the parts involved in the structure of the feeding device are relatively more. In addition, the feeding device and the (fixed and movable) chucks are separated in structure, so that adjustment of corresponding dimensions is easier to realize by adding parts and the like.

Specifically, through the arrangement of the lifting component, the lifting device can realize the lifting of the supporting plate in the height direction and simultaneously realize the fine adjustment of different parts of the workpiece to be machined in the lifting height. Through the setting of clamping component, when waiting to work piece to press from both sides tight, can also realize waiting that the fine setting of different parts of machined part in the clamping position. The adjustment to which the present invention relates therefore comprises the following three dimensions: height (hereinafter, positional adjustment along the Z axis), height deviation (hereinafter, angular adjustment along the X axis), and horizontal rotation (hereinafter, directional adjustment along the Z axis).

It will be appreciated that the structural form of the lifting assembly and its implementation of two dimensional adjustment of the workpiece to be machined disposed on the pallet can be determined by a person skilled in the art according to the actual requirements. Illustratively, it is assumed that the lift assembly includes a mechanism 1 and a mechanism 2, wherein the mechanism 1 enables height adjustment and the mechanism 2 enables height deviation adjustment. The method can be as follows: the mechanism 1 and the mechanism 2 can be operated independently, so that the adjustment of the height and the adjustment of the height deviation can be effected spatially and temporally (e.g. simultaneously or in any order); mechanism 1 and mechanism 2 are cooperatively related in motion so that the adjustment of altitude and the adjustment of altitude deviation are accomplished simultaneously or in a specific order (e.g., altitude adjustment followed by altitude deviation adjustment); etc.

Obviously, the mechanism 1 and the mechanism 2 can be of any structural form, as long as the workpieces to be processed can be lifted and deviations in lifting height can be generated. Such as mechanism 1 and mechanism 2 may be separate mechanisms or have associated mechanisms (e.g., partially structurally overlapping each other, one forming part of the other, connected by an intermediate member, etc.).

It will be appreciated that, according to practical requirements, a person skilled in the art may determine the structural form of the adjustment assembly and its configuration in the clamping first end assembly and/or the clamping second end assembly and the specific configuration position, where the clamping second end assembly and the clamping first end assembly may be both a movable end or one may be a fixed end and one may be a movable end. Illustratively, the adjustment assemblies are disposed on the clamping first end assembly and the clamping second end assembly, respectively. The adjusting component can be a structure additionally arranged on the clamping first end component and the clamping second end component, or can be a structure formed by combining part of the existing structures of the clamping first end component and the clamping second end component with each other. The adjustment assembly is illustratively a self-contained structure that adjusts the angle of the workpiece along the Z-axis in such a way that different portions of the workpiece are different from the distance between the respective clamping first end assembly and/or clamping second end assembly. If the adjusting assembly comprises a mechanism 3 and a mechanism 4, the mechanism 3 and the mechanism 4 are respectively configured outside the clamping first end assembly and the clamping second end assembly, and the mode that the mechanism 3 can push one end of the clamping first end assembly (along the length direction of the workpiece to be processed) to displace in the first direction and the mechanism 4 can push the other end of the clamping second end assembly to displace in the opposite direction of the first direction enables different parts of the workpiece to be processed to be different from the corresponding distance between the clamping first end assembly and/or the clamping second end assembly, so that the angle adjustment of the workpiece to be processed along the Z axis is realized.

For the above feeding device, in one possible embodiment, the feeding device further includes: 2) The feeding table assembly comprises a feeding platform, a discharging platform and a driving transmission mechanism, wherein the driving transmission mechanism drives the feeding assembly carrying the to-be-processed workpiece to move along the direction between the feeding platform and the discharging platform, and therefore the position state of the to-be-processed workpiece along the moving direction is adjusted.

With this configuration, the feed height of the workpiece to be machined is increased from the fourth dimension on the basis of the three dimensions.

Specifically, by arranging the driving transmission mechanism, the driving transmission mechanism can realize the basic functions of feeding and discharging, and can also realize feeding precision adjustment along the feeding and discharging direction (hereinafter, position adjustment along the X axis).

It can be appreciated that, in order to ensure that the accuracy adjustment can reach the standard, a person skilled in the art can directly utilize the driving transmission mechanism corresponding to the basic transfer function according to actual requirements, add a certain structure and/or add a certain control logic on the basis of the driving transmission mechanism, and the like.

For loading attachment, in one possible embodiment, the lifting assembly includes: a first driving part; the lifting wheel set comprises a plurality of lifting wheels, the first driving component is in driving connection with the lifting wheels, and the lifting wheels are in operation connection with the supporting plate; the first driving component can drive the lifting wheel to rotate so as to lift the supporting plate and a workpiece to be machined arranged on the supporting plate; the lift assembly further includes: an adjusting part which is in signal connection with at least the lifting wheel so as to: the lifting heights of the supporting plates corresponding to the positions of the lifting wheels are different.

By this construction, a specific construction of the lifting assembly is given.

The drive connection in the expression "drive connection of the first drive part to the lifting wheel" should be understood as: when the first driving part is driven, the lifting wheel generates the action related to the driving action, namely, the lifting wheel generates actions such as lifting and the like in response to the driving of the first driving part. For example, the first drive member may be in direct drive connection or in indirect drive connection with the lifting wheel.

It should be noted that the operation connection in the "operation connection of the lifting wheel and the pallet" should be understood as: when one of the lifting wheel and the supporting plate acts, the other concomitantly acts in association with the action, namely the two have an association at the operation level, such as a direct association or an indirect association between the two.

The term "adjusting part, which is connected to at least the lifting gear signal", is understood to mean: according to different control instructions of the adjusting part, the lifting wheel can generate lifting heights corresponding to the instructions. It is obvious that a person skilled in the art can formulate a mapping relation between the control command and the lifting height according to actual requirements. In other words, based on such signal connection, the mapping relationship between the control command and the lifting height can be flexibly selected according to the actual requirement, and the map can be known, conventionally selected or flexibly formulated according to the actual situation, etc.

It will be appreciated that the person skilled in the art can determine the form, number, relative position between the individual lifting wheels (in case the lifting wheels comprise a plurality) and their relative position with the pallet, of the lifting wheels comprised in the lifting wheel set, according to the actual need. The method can be as follows: the lifting wheels comprise two groups, and the setting positions of the two groups of lifting wheels are close to the two ends of the silicon rod; the lifting wheels comprise four groups, respectively designated A, B, C, D, wherein A and C are one group, the silicon rods arranged on the supporting plate can be lifted in a first form by means of the lifting wheels (A, C), B and D are one group, and the silicon rods arranged on the supporting plate can be lifted in a second form by means of the lifting wheels (B, D); etc.

It is understood that a specific form of the first driving member driving the lifting wheel set to displace and a corresponding relationship between the driving member and the lifting wheel set can be determined by a person skilled in the art according to actual needs. For example, the first driving part can enable the lifting wheel set to displace in a direct driving or indirect driving mode. The form of indirect drive may be: the power output end of the first driving part is directly connected with one or a plurality of intermediate parts, and when the state of the first driving part driving the intermediate parts is changed, the lifting wheel can generate displacement along the height direction based on the state change. And, the correspondence between the first driving parts and the lifting wheel sets may be one-to-one correspondence, one first driving part corresponds to a plurality of lifting wheels, one lifting wheel corresponds to a plurality of first driving parts, and the like. The lifting wheel comprises two, two first drive members driving the two lifting wheels respectively in a relatively independent manner.

It will be appreciated that the direction of displacement of the lifting wheel under the drive of the first drive member and the amount of displacement can be determined by a person skilled in the art according to the actual need. As for the direction therein, the displacement may be a displacement including only the height direction, or may be a displacement including, but not limited to, other directions such as the horizontal direction. As for the displacement amount thereof, a person skilled in the art can set how the driving member makes the lifting wheel to make a desired displacement amount according to a driving manner in which the first driving member drives the lifting wheel to make a displacement, a displacement amount required for a workpiece to be machined, and the like.

It will be appreciated that the specific structural form of the pallet may be determined by a person skilled in the art according to the actual requirements, such as being directly arranged on the pallet or adding a corresponding functional structure to the pallet and then arranging the workpiece to be machined on the functional structure.

For the above-mentioned loading device, in one possible embodiment, a part of the plurality of lifting wheels is fixedly connected to the pallet in a rotatable manner, the lifting assembly further comprises a transmission member connected to the first driving member on the one hand and to the lifting wheels on the other hand, wherein the transmission member has an inclined guiding surface in a position close to the lifting wheels such that: when the first driving part drives the transmission part to transversely move, the lifting wheel rotates along the guide surface and accordingly lifts the supporting plate and a workpiece to be machined arranged on the supporting plate; another part of the plurality of lifting wheels is provided with an eccentric shaft provided with a second driving part such that: the second driving component drives the eccentric shaft to rotate and/or the lifting wheel corresponding to the eccentric shaft to rotate around the eccentric shaft, so that the heights of the supporting plate and different parts of the workpiece to be machined arranged on the supporting plate are allowed to be different.

By means of the structure, a specific implementation mode of the lifting assembly for achieving feeding precision adjustment in two dimensions is provided.

It should be noted that, rotation in "a part of the plurality of lifting wheels is fixedly connected to the pallet in a rotatable manner" is understood to be a rotation property of the lifting wheels, and a fixed connection is understood to be a connection relationship between the lifting wheels and the pallet. Illustratively, if the lift wheel is configured with a shaft that is fixedly connected to the pallet, the lift wheel may spin about the shaft. The pallet is illustratively a generally housing structure to which the work piece to be machined is secured, and the lift wheel is mounted on the side of the housing structure by an axle.

It will be appreciated that the configuration, number and specific movement pattern of the transmission members, which are generated by the first driving member, etc. may be determined by those skilled in the art according to actual requirements. For example, the transmission component can be a plate-shaped structure, a block-shaped structure, a strip-shaped structure and the like, and the movable form of the transmission component can comprise movement, rotation, combination of the two and the like. For example, the plurality of lifting wheels may share one transmission member, each lifting wheel is provided with a plurality of transmission members, and the number of lifting wheels and transmission members is in one-to-one correspondence.

The inclined guide surface is understood here as: the downstream side of the guide surface should have a lower height than the upstream side of the guide surface, as seen in the traversing direction of the transmission member. The guiding surface having such features may be a ramp, a (concave, convex) curved surface, a combination thereof, or the like. Taking the first driving part as a power cylinder and the guiding surface as an inclined surface as an example, the transmission part transversely moves along with the extension of the power output shaft of the power cylinder, and due to the arrangement of the inclined surface, the lifting wheel generates vertical upward displacement along with rotation and rolling on the inclined surface, so that the supporting plate can be driven to generate displacement along the vertical direction, and the lifting of a workpiece to be machined is realized. The first driving member may be a power cylinder or a motor, for example. The power cylinder can be an electric cylinder, an air cylinder, a hydraulic cylinder and the like. At this time, the transmission member is directly connected to the piston as a power output shaft. In the case where the driving member is a motor, the shaft of the motor should be indirectly connected to the driving member by a transmission mechanism such as a lead screw nut pair to achieve lateral movement of the driving member. Since the second driving member is mainly used for driving the eccentric shaft to rotate, the second driving member is typically a motor.

The lifting heights among the lifting wheels are differentiated under the action of the transmission component through the synthetic motion formed by the rotation of the lifting wheels around the eccentric shaft and the rotation of the eccentric shaft, so that the difference of the lifting heights of different positions of the part to be machined is realized.

It will be appreciated that the person skilled in the art can determine the specific specifications of the eccentric shafts and the specific number and positions of the eccentric shafts arranged in the lifting wheel, etc. according to the actual requirements, the lifting wheel comprises, for example, two lifting wheels, one of which is a common shaft and the other of which is an eccentric shaft.

For the above feeding device, in one possible embodiment, the lifting assembly includes a restraining member, and the pallet is displaced in a height direction under the cooperation of the restraining member, and thus lifts the pallet and the workpiece to be machined disposed on the pallet in a vertical direction.

With this configuration, the reliability of the lift assembly can be ensured.

In particular, the lifting path of the pallet is defined by the guiding and/or limiting action of the constraining means. It will be appreciated that the structural form, number, relationship with the pallet, etc. of the guiding and limiting members can be determined by those skilled in the art according to actual requirements. The method can be as follows: the guiding and limiting part comprises a baffle plate/baffle rib which is arranged outside the supporting plate in a surrounding way, a guide rail which is matched with the supporting plate, and the like.

For the above feeding device, in one possible implementation manner, the constraint component is a connection shaft, a hole is formed in the supporting plate, and the connection shaft is freely accommodated in the hole.

By this construction, a specific construction of the restriction device is provided.

For the above feeding device, in one possible embodiment, the pallet includes a first bottom plate, and the lifting assembly includes a return spring, where the return spring is disposed between the first bottom plate of the lifting assembly and the pallet.

By this construction, a specific construction of the lifting assembly is given.

Specifically, through the arrangement of the reset spring, the supporting plate can be reliably reset. The return spring is in a stretched state when the power output shaft (piston) of the power cylinder stretches out and the supporting plate lifts. When the power output shaft of the power cylinder retracts, the supporting plate descends under the combined action of the pulling force of the return spring and the gravity of the supporting plate, so that the supporting plate is returned.

It will be appreciated that those skilled in the art may determine the specifications (e.g., spring rate, etc.) of the return spring, the number of settings, the location of the settings, the specific manner of connection of the base plate and the pallet, etc., according to actual needs. Illustratively, taking the constraining member as an axle, for example, the return spring includes a plurality of springs distributed circumferentially about the axle. In addition, a return spring may be provided outside the connecting shaft.

For loading attachment, in one possible embodiment, the adjustment assembly includes: the clamping first end assembly and/or the clamping second end assembly are/is movably arranged on the second bottom plate; a third drive member operatively connected to the respective said clamping first end assembly or said clamping second end assembly for: the distance between the respective clamping first end assembly or the clamping second end assembly and different portions of the second base plate is different under the drive of the third drive member.

By means of the structure, a specific implementation mode of the adjusting component for realizing feeding precision adjustment of one dimension of the adjusting component is provided. Specifically, the fine adjustment of the angle of the silicon rod to be ground to be machined in the feeding/clamping direction can be realized.

The term "third drive member operatively connected to the respective clamping first end assembly and/or clamping second end assembly" is to be understood as: when the third drive member is actuated with one of the respective clamping first end assembly and clamping second end assembly, the other is concomitantly actuated in association with the actuation, i.e. both have an association at the operational level, e.g. a direct drive connection or an indirect drive connection between the third drive member and the clamping first/second end assembly.

It will be appreciated that the second base plate may be directly or indirectly coupled to the first/second end assemblies to be clamped, and that the difference in distance between the different parts may be achieved by rotation, movement or a combination of both. The method can be as follows: the displacement of the second bottom plate and the clamping first/second end assembly at the first position is first displacement, and the displacement at the second position is second displacement different from the first displacement, so that different local distances between the second bottom plate and the clamping first/second end assembly can be realized; the second bottom plate and the first/second bottom plate can generate rotation quantity and moving quantity along the thickness direction (clamping direction) of the second bottom plate, and different local distances between the second bottom plate and the first/second bottom plate are different through the two moving quantities; etc.

It is understood that one skilled in the art may configure the adjustment assembly for clamping the first/second end assemblies according to actual needs. Illustratively, if the mounting position of the clamping first end assembly is relatively fixed, configuring the adjusting assembly for clamping the first end assembly may effectively prevent the adjusting amount of the adjusting assembly from interfering with other movements.

For the above feeding device, in one possible implementation manner, the second bottom plate reserves an installation space, and the adjusting component includes: a first adjusting member provided to the clamping plate clamping the first end assembly and/or the second end assembly, the first adjusting member being freely accommodated in the installation space and having a first adjusting structure protruding out of the installation space; a second adjusting member drivingly connected to the third driving member and having a second adjusting structure inclined at a side portion close to the first adjusting member such that: when the third driving part drives the second adjusting part to move towards the direction close to the first adjusting part, the second adjusting structure props against the first adjusting structure so as to drive the clamping plate and the second bottom plate to rotate relatively, and therefore distances between different parts of the clamping plate and the second bottom plate are different.

By such a construction, a specific construction of the adjustment assembly is given.

In particular, a different distance from different parts of the clamping plate and the second base plate is achieved by means of cooperation with the first and second adjustment structures.

It is understood that the structural form of the first/second adjusting member, the specific structural form of the first/second adjusting structure, the arrangement position, the arrangement manner, etc. of the first/second adjusting structure on the first/second adjusting member can be flexibly selected by those skilled in the art according to actual needs.

For example, the first/second adjustment structures may be fixedly connected or integrally formed on the first/second adjustment members, and the cross section (along the thickness direction of the second bottom plate) of the first adjustment structure may be an arc surface, an inclined surface, or the like. Illustratively, the first adjustment component is integrally formed with the first adjustment structure and is a generally arcuate-ended cylindrical block.

Tilting as in the "tilting second adjustment structure" is to be understood as: the height of the downstream side of the second adjustment structure should be lower than the height of the upstream side, as seen in a direction away from the first adjustment member toward the first adjustment member. The second adjustment structure having such features may be a ramp, (concave, convex) curved surface, a combination thereof, or the like. Illustratively, the second adjustment component is integrally formed with the second adjustment structure and is generally a wedge-shaped block.

For the above feeding device, in one possible implementation manner, the first adjusting component is an adjusting top block and/or the second adjusting component is an adjusting wedge block.

By this construction, a specific structural form of the first/second adjusting member is given.

For the above feeding device, in one possible embodiment, the adjusting component includes: the adjusting plate is arranged between the second bottom plate and the clamping plate, wherein the second bottom plate is movably connected with the adjusting plate, and the first adjusting part is fixedly connected with the adjusting plate or integrally formed with the adjusting plate.

By means of this construction, a specific design of the adjusting assembly is provided.

In particular, since the clamping plate has strict specifications in terms of accuracy or function, in addition, it is possible to cooperate with other components, as corresponds to the assumption that the clamping plate clamping the first/second end assembly is of a movable component. Therefore, the arrangement of the adjusting plate can avoid the influence of the realization of the adjusting function of the invention on the basic clamping performance of the original clamping assembly.

For the above feeding device, in one possible implementation manner, the adjusting plate is fixedly connected with the clamping plate or integrally formed.

It will be appreciated that the specific manner of connection of the adjustment plate to the first adjustment member and the clamping plate may be determined by a person skilled in the art according to the actual requirements. For example, the connection can be screw connection, clamping connection, bonding and the like.

For the above feeding device, in one possible embodiment, the adjusting component includes: a positioning member fixedly provided on the second bottom plate; and the adjusting plate is provided with a reserved space at a position corresponding to the positioning component; wherein, the locating component is in the clearance has between the part of headspace and the headspace for: and the clamping plate and the second bottom plate are enabled to rotate relatively through the movement of the positioning part in the reserved space.

By this construction a specific way of connection between the adjusting plate and the base plate is given.

When the relative rotation occurs, the position corresponding to the positioning block corresponds to the pivoting side, and the position corresponding to the first adjusting member corresponds to the free side. Therefore, in order to ensure the realization of the rotation, the installation position of the installation space corresponding to the first adjusting part and the installation space corresponding to the positioning block on the adjusting plate should have a distance.

For the above feeding device, in one possible embodiment, the adjusting component includes: the positioning part is a positioning block.

By this construction, a specific construction of the positioning element is provided.

For the feeding device, in one possible embodiment, the position of the supporting plate near the middle part on one side near the workpiece is a structure recessed in a direction far away from the workpiece when viewed along the length direction of the workpiece.

With this configuration, the workpiece can be more reliably mounted on the pallet.

For the above feeding device, in one possible implementation manner, the supporting plate includes a supporting plate main body and a supporting plate, and the workpiece to be processed is disposed on the supporting plate, where a position of the supporting plate, which is close to the middle part, on one side of the workpiece to be processed is a structure that is concave in a direction away from the workpiece to be processed.

By this construction, a specific construction of the pallet is given.

For the feeding device, in one possible implementation manner, the supporting plates comprise two groups which are arranged separately, and each group of the supporting plates comprises at least one supporting plate, and a structure recessed in a direction away from the workpiece is formed between the two groups of the supporting plates; or the supporting plate is of an integrally formed structure, and a structure recessed in a direction away from the workpiece to be processed is formed at a position close to the middle of the supporting plate.

By this construction, a possible way of forming the recess in the pallet is given.

In a second aspect, the invention provides a grinding machine comprising a loading device according to any one of the preceding claims.

It will be appreciated that the grinding machine has all the technical effects of the feeding device described in any one of the foregoing, and will not be described in detail herein.

For the above-mentioned grinding machine, in one possible embodiment, the grinding machine is a grinding machine for machining silicon rods.

With such a constitution, a specific form of the workpiece to be processed is given.

In a third aspect, the present invention provides a feeding control method of a grinding machine, the grinding machine including a feeding device and a grinding device, the grinding device including a grinding assembly and a detection assembly, the control method including: judging whether the state of the workpiece to be machined meets the condition that the grinding assembly grinds the workpiece to be machined or not according to the detection result of the detection assembly; if not, selectively placing the workpiece to be machined in the feeding device, and adjusting at least part of the state of the workpiece to be machined through the feeding device, wherein the method comprises the following steps: the position state of the workpiece to be machined in the vertical direction is adjusted through the first adjusting part; the position states of different parts of the workpiece to be machined along the vertical direction are adjusted through the second adjusting part; the position states of different parts of the workpiece to be machined along the feeding and discharging directions are adjusted through a third adjusting part; and adjusting the position state of the workpiece to be machined along the feeding and discharging directions through a fourth adjusting part.

By adopting the structure, the to-be-machined part can be in a state meeting grinding conditions in a mode of adjusting the to-be-machined part in four dimensions in the feeding link, and the to-be-machined part is a silicon rod or the like.

It will be appreciated that the base unit may take all possible connection forms, provided that it has the base unit described above and that it is possible to ensure that the control method is implemented. In other words, this solution obviously has all the technical effects of the lifting assembly of any one of the previous claims, which are not repeated here.

Compared with the mode of manually participating in directly blanking the to-be-machined part (rod withdrawing), the invention directly places the to-be-machined part in the feeding device for readjustment (repeated), thereby improving the adjustment efficiency on the premise of ensuring the precision. Compared with the adjustment in the feeding direction by the (fixed and movable) chucks, the feeding precision adjustment in four dimensions can be realized by different parts because the parts involved in the structure of the feeding device are relatively more. In addition, the feeding device and the (fixed and movable) chucks are separated in structure, so that adjustment of corresponding dimensions is easier to realize by adding parts and the like.

It should be noted that "selectively placing the workpiece to be processed on the loading device" should be understood as follows: the condition that the condition of the workpiece to be machined does not meet the condition that the grinding assembly grinds may include the need to directly withdraw the rod, the need to readjust but the feeding device cannot achieve such adjustment, the need to readjust and the adjustment can be achieved by the feeding device (only by the feeding device or the cooperation of the feeding device and other devices, etc.), and so on. Therefore, the workpiece to be processed is effectively controlled by the feeding device only under the condition that the workpiece to be processed needs to be readjusted and the adjustment can be realized through the feeding device.

For the above feeding control method, in one possible implementation manner, the first adjusting portion includes a lifting assembly, the lifting assembly includes a first driving component, a lifting wheel set and a supporting plate, the lifting wheel set includes a plurality of lifting wheels, and accordingly, the "adjusting the position state of the workpiece to be processed along the vertical direction by the first adjusting portion" includes: the first driving part is enabled to operate, the lifting wheel is driven to rotate through the first driving part, so that the supporting plate is lifted, the workpiece to be machined is arranged on the supporting plate, and the position state of the workpiece to be machined along the vertical direction is adjusted.

By this configuration, a specific structural form of the first adjusting portion and a specific manner in which adjustment of the first dimension (hereinafter, positional adjustment along the Z axis) is achieved are given.

For the above feeding control method, in one possible implementation manner, the lifting assembly further includes a transmission component, where the transmission component has an inclined guiding surface near the lifting wheel, and accordingly, the "driving the lifting wheel to rotate by the first driving component to lift the supporting plate and the workpiece to be machined disposed on the supporting plate" includes: when the first driving part drives the transmission part to transversely move, the lifting wheel rotates along the guide surface, and accordingly lifts the supporting plate and a workpiece to be machined arranged on the supporting plate.

By this constitution, a specific form of adjusting the feeding accuracy by the first adjusting portion is given.

For ease of description, the present invention first defines a three-dimensional coordinate system of such a silicon rod. The center of the silicon rod is the origin, the reverse direction of the feeding direction of the silicon rod on the grinding machine is the X-axis forward direction, the feeding direction of the silicon rod on the grinding machine is the Y-axis forward direction, and the vertical upward direction is the Z-axis forward direction. Based on the above, the precision adjustment realized by the feeding assembly mainly comprises four dimensions: the silicon rod is lifted by a certain distance along the Z axis (hereinafter referred to as positional adjustment along the Z axis), moved by a certain distance along the X axis (hereinafter referred to as positional adjustment along the X axis), rotated by a certain angle about the Z axis direction (hereinafter referred to as angular adjustment along the Z axis), and rotated by a certain angle about the X axis direction (hereinafter referred to as angular adjustment along the X axis). According to the orientation of fig. 1, the X-axis forward direction is from back to front, the Y-axis forward direction is from left to right, and the Z-axis forward direction is vertically upward. Correspondingly, the position along the X/Y/Z axis is adjusted to be moved a certain distance in the front-back/left-right/vertical direction, and the angle along the X/Y/Z axis is adjusted to be rotated a certain distance in the front-back/left-right/vertical direction.

The present invention is described below with reference to some or all of fig. 1 to 18.

Referring mainly to fig. 1, in one possible embodiment, the main body of the grinding machine 1 mainly includes a base 101 and a bottom vertical frame 102, where the base 101 has a certain level adjustment function, so as to provide a mounting surface with a higher level for the structures such as the feeding device 11 and the grinding device 13 of the grinding machine 1. Wherein a guide rail is provided at the top of the vertical frame 102, and the feed slide apparatus 12 is mounted on the guide rail. The grinding machine is mainly used for grinding the silicon rod 2 which is used as a workpiece to be machined after being cut to a set specification. Specifically, in an ideal state, the silicon rod 2 after being opened is generally rectangular parallelepiped with equal width and height. In practice, however, the surface of the silicon rod 2 after the prescription is not flat, as it is generally expressed as: the middle part of the silicon rod is protruded compared with the two end parts, the dimension of the outlet edge of the silicon rod is larger than the dimension of the inlet edge (the side length of the square of the cutting end face of the diamond wire is larger than the side length of the square of the cutting end face of the diamond wire). Therefore, it is necessary to grind the silicon rod after the square-cut to an ideal rectangular parallelepiped of standard specification by a grinder.

Referring mainly to fig. 2 and 3, in one possible embodiment, the loading device 11 is mainly used to clamp the silicon rod 2 by the fixed chuck 121 and the movable chuck 122 of the feed slide device 12 after the silicon rod is adjusted to a proper position and angle. In order to reduce the grinding amount, reduce silicon loss and improve grinding efficiency, the grinding machine 1 needs a high feeding precision. Under the condition that the feeding precision reaches the standard, the ideal axis of the silicon rod 2 and the axis between the fixed chuck and the movable chuck should have higher coaxiality. The coaxiality of the feeding device is enabled to reach an ideal level mainly through adjustment of the feeding device.

In one possible embodiment, the loading device 11 mainly includes a loading assembly 111, a centering assembly 112, and a loading table assembly 113. The position and posture (hereinafter referred to as pose) of the silicon rod 2 need to be adjusted in the aforementioned four dimensions by the feeding assembly 111 and the feeding table assembly 113, and the centering assembly 112 is used for mainly determining the adjustment amount of the pose of the feeding assembly 111 to the silicon rod 2. Specifically, the loading assembly 111 generally includes a lifting assembly 1111 and a clamping assembly 1112. Based on the detection result of the centering assembly 112, the lifting assembly 1111 is mainly used for adjusting the position of the silicon rod 2 along the Z axis and adjusting the angle of the silicon rod 2 along the X axis (rotation in the vertical plane), and the clamping assembly 1112 is mainly used for adjusting the angle of the silicon rod 2 along the Z axis (rotation in the horizontal plane). The loading table assembly 113 is mainly used for adjusting the position of the silicon rod along the X axis in the process of moving the loading assembly 111 holding the silicon rod 2 to the centering assembly 112. Based on the above, after the feeding assembly 111 completes the adjustment of the silicon rod in four dimensions, the (fixed and movable) chucks clamp the silicon rod with the pose reaching the standard, so that the feeding process is completed.

Referring primarily to fig. 4-7, in one possible embodiment, the lifting assembly 1111 basically includes a first base plate 11111, an electric cylinder 11112 (first drive member), a drive plate 11113 as a drive member, a lifting wheel set including a first lifting wheel 111141 (e.g., the first lifting wheel includes two wheel units disposed on a first axle 111191) and a second lifting wheel 111142, and a support plate 11115, the drive plate 11113 having a left-to-right downward sloped surface 111131 as a guide surface at positions corresponding to the first and second lifting wheels 111141 and 111142, respectively.

In this example, the power take-off shaft of the electric cylinder 11112 is connected to the drive plate 11113 in the following manner: the first base plate 11111 is provided with a connecting block 11116 as a connecting member, the connecting block 11116 is fixedly connected with a transmission plate 11113 above the first base plate 11111 by means of fasteners such as screws, on one hand, an extending end is arranged below the connecting block 11116, correspondingly, a ring groove matched with the extending end is arranged on a power output shaft of the electric cylinder 11112, and the connecting block 11116 is connected with the electric cylinder 11112 by matching the extending end with the ring groove.

Thus, when the power output shaft of the electric cylinder 11112 extends rightward, the transmission plate 11113 disposed at the bottom of the housing is driven to move rightward synchronously. In accordance with this, the two lifting wheels mounted on the pallet 11115 can then roll along the inclined plane 111131 from right to left, i.e. from low to high, and with this rolling, the pallet can be driven to displace in the vertical direction. In this way, the silicon rod disposed on the pallet 11115 achieves positional adjustment along the Z-axis. Similarly, the power take off shaft of the electric cylinder 11112 is retracted, the drive plate 11113 is moved to the left, the lift wheel rolls from high to low, and the pallet 11115 is lowered. For example, for better guiding the movement of the drive plate 11113, a rail can be provided on the first base plate 11111, which rail is adapted to the movement path of the drive plate 11113.

As described above, one of the manifestations of the surface unevenness of the silicon rod 2 after the opening is: the middle portion of the silicon rod is convex compared with the two end portions. In order to be able to place the silicon rod having this property on the pallet more smoothly, the middle of the pallet is recessed in a direction away from the silicon rod, i.e. downwardly in the figure, than on both sides.

Illustratively, the pallet 11115 includes a pallet body 111151, two sides extending along the length direction of the top of the pallet body are respectively provided with an upwardly extending supporting plate 111152 (such as mainly made of nylon, etc.), the upper surface of the supporting plate 111152 is a reference surface (such as referred to as a reference surface a) directly contacting the lower surface of the silicon rod 2, and the position of the supporting plate near the middle forms the aforementioned recess, as a specific implementation manner is: each side is provided with two support plates 111152 arranged separately, for example, the support plates can be fixed to the top of the pallet by means of fasteners such as screws, and a recess is formed between the two support plates. In this example, the support plate has a structure of avoiding the silicon rod at the mounting portion corresponding to the fastener, such as a plurality of mounting positions provided on the support plate, the screw is provided at a position corresponding to the mounting position, and in the mounted state, the screw is completely accommodated at the mounting position and thus the top of the screw is not in contact with the bottom of the silicon rod.

It will be appreciated that the manner in which the pallet is recessed may be flexibly adjusted by those skilled in the art according to actual needs, such as by integrally providing two separate support plates and then providing the central portion as a recess, integrally providing the support plates with the pallet body, etc.

In one possible embodiment, the first base plate 11111 is provided with a connecting shaft 1117 that mates with the pallet 11115, and a return spring 1118 is also provided between the first base plate and the pallet. By the arrangement of the connection shaft 1117, the movement of the pallet 11115 in the X-axis and Y-axis directions is restricted, so that the pallet 11115 can move only in the Z-axis direction under the guidance of the connection shaft. When the cylinder 11112 is extended and the pallet 11115 is raised, the return spring 1118 is in a compressed/stretched (as in this example, compressed) state. When the cylinder 11112 is retracted, the pallet 11115 is lowered under the combined action of the spring force of the return spring 1118 and the weight of the pallet 11115 itself, effecting a return of the pallet 11115. As in the present example, the pallet is provided with a hole, and the connection shaft is freely accommodated in the hole so that the pallet can be smoothly raised (lifted)/lowered (returned) in the axial direction of the connection shaft. The bottom of connecting axle and first bottom plate fixed connection or integrated into one piece, the top of connecting axle has the radial dimension that is greater than the hole, and the required lifting volume of silicon rod can be guaranteed to the axial dimension of connecting axle.

As in the present example, the pallet body of the pallet is a substantially open-bottomed enclosure structure with the aforementioned support plates disposed on top of the enclosure structure and the lifting wheels disposed on the sides of the enclosure structure. Illustratively, the two lift wheels are mounted to the pallet 11115 in the following manner: the first and second lift wheels 111141 and 111142 are mounted to sides of the enclosure structure by first and second axles 111191 and 111192, respectively. As the cylinder 11112 extends/retracts, the pallet 11115 is raised/reset by the rotation of the two lift wheels and its rolling on the ramp 111131. Based on this, the function of the lift assembly 1111 may be improved, in particular, the lift assembly may have a function of adjusting the position adjustment of the silicon rod along the Z-axis while also having a function of adjusting the angle adjustment of the silicon rod along the X-axis.

On the basis, the lifting assembly has the function of adjusting the angle adjustment of the silicon rod along the X axis in addition to the function of adjusting the position of the silicon rod along the Z axis. In the present invention, the function of the lift assembly 1111 is improved.

In one possible embodiment, one of the first axle 111191 and the second axle 111192 may be changed to an eccentric (labeled 111191) as in this example, the first axle 111191 corresponding to the first lifting wheel 111141 is changed to an eccentric, and the eccentric is configured with a first adjustment motor 1111911 as in the case of a first adjustment motor (second drive component) connected to the eccentric via a reducer-coupling. Thus, when the first adjustment motor drives the eccentric shaft corresponding to the first lifting wheel to rotate a certain angle, the first lifting wheel 111141 installed on the eccentric shaft lifts/descends a certain distance, and at this time, the supporting plate 11115 rotates a certain angle around the X axis due to the height difference between the two lifting wheels, so that the angle adjustment of the silicon rod along the X axis is realized. In response, the pivot bearing 11171 is mounted on the connection shaft 1117, so that the connection shaft is configured to limit movement of the pallet 11115 in the X-axis and Y-axis directions only, and not to limit rotation of the pallet 11115 about the X-axis. In an actual product, for example, a mounting position corresponding to the first adjustment motor may be provided at a position corresponding to each of the first lift wheel 111141 and the second lift wheel 111142, and in this example, a removable seal plate 1111921 may be provided at a position corresponding to the second lift wheel 111142. By removing the sealing plate, the first adjustment motor can be replaced to a position corresponding to the second lift wheel 111142.

Therefore, the silicon rod on the supporting plate can be lifted to a certain height along the vertical direction through the cooperation of the electric cylinder, the transmission plate and the lifting wheels (the first lifting wheel and the second lifting wheel). Through the cooperation of the first adjusting motor, the eccentric shaft and the first lifting wheel, the positions of different parts of the silicon rod on the supporting plate along the height direction can be distinguished. In this way, the position adjustment of the silicon rod along the Z axis and the angle adjustment along the X axis can be realized through the lifting assembly.

Referring primarily to fig. 8-12, in one possible embodiment, the clamping assembly 1112 basically includes a clamping movable end assembly 11121 and a clamping fixed end assembly 11122, with the clamping movable end assembly 11121 being opposite the clamping fixed end assembly 11122, capable of clamping the silicon rod 2 on the reference surface a of the pallet 11115 in the X-axis direction. It should be noted that the clamping movable end assembly and the clamping fixed end assembly are only one specific form of the clamping assembly, for example, the clamping movable end assembly and the clamping fixed end assembly may be both provided in a movable form.

In one possible embodiment, the clamping movable end assembly 11121 mainly includes a first cylinder 111211, two sets of guide rail sliders (an X-axis guide rail slider 111212, a Y-axis guide rail slider 111213), a movable end return spring 111214, and a movable clamping plate 111215, after the silicon rod 2 to be ground is placed on the reference surface a of the lifting assembly 1111, the first cylinder 111211 is extended, and by pushing the bottom plate of the clamping movable end assembly 11121, the slider of the X-axis guide rail slider 111212 slides on the guide rail to push the movable clamping plate 111215 to move toward the clamping fixed end assembly 11122, so that the silicon rod is clamped along the X-axis direction. When the (fixed and movable) chucks clamp the silicon rod, the movable chuck 122 pushes the silicon rod to move slightly along the Y-axis, and accordingly, the movable clamping plate 111215 also moves slightly along the Y-axis in a manner that the slide block of the Y-axis guide rail slide block slides on the guide rail, and such movement can make the two movable end return springs 111214 arranged along the Y-axis direction respectively in a compressed state and a stretched state. After the (stationary and moving) clamp grips the silicon rod, the first cylinder 111211 is retracted, while the two movable end return springs 111214 are restored, resetting the movable clamp plate 111215.

In one possible embodiment, the clamp-on, fixed-end assembly 11122 generally comprises a fixed clamp plate 111221 and an adjustment assembly. The fixed clamping plate is provided with a reference surface b, and the movable end clamping plate is driven to move towards the direction close to the fixed end clamping plate through the first cylinder 111211, so that the silicon rod can be clamped along the X direction. Similar to the structure and function of the clamp movable end assembly 11121, the clamp fixed end assembly 11122 is also provided with a Y-axis rail slider and a fixed end return spring that enable the movable end clamp plate to return. The adjusting component is mainly used for realizing the angle adjustment of the silicon rod along the Z axis.

In one possible embodiment, the adjustment assembly mainly includes a second base plate 1112221, an adjustment plate 1112222, and a positioning block 1112223, wherein the positioning block 1112223 may be fixed to the second base plate 1112221 by a fastener such as a screw a11122231, and the adjustment plate 1112222 is fixed to a fixed clamping plate located on one side thereof, and the adjustment plate 1112222 is mounted to the second base plate 1112221 located on the other side thereof (a position near the left side) by the positioning block 1112223. Wherein a gap exists between the positioning block 1112223 and the adjustment plate 1112222, thereby allowing small-angle rotation of the adjustment plate 1112222 about the Z-axis. In this way, by changing the included angle between the adjusting plate 1112222 and the second bottom plate 1112221, the silicon rod 2 clamped between the fixed end clamping plate and the movable end clamping plate can rotate around the Z axis, thereby realizing the angle adjustment of the silicon rod 2 along the Z axis.

In one possible embodiment, the adjusting assembly further comprises an adjusting motor (third driving part) 1112224, an adjusting top block (first adjusting block, wherein "top" is a form of the first adjusting structure) 1112225 and an adjusting wedge (second adjusting block, wherein "wedge" is a form of the second adjusting structure) 1112226, and the invention is mainly based on the second bottom plate 1112221, the adjusting plate 1112222 and the positioning block 1112223, and the angle of the silicon rod 2 along the Z axis is adjusted by cooperation of the adjusting top block and the adjusting wedge. As in the present example, the second adjustment motor 1112224 is a stepper motor. The second bottom plate 1112221 has a mounting space reserved at a position corresponding to the adjustment top block (a position near the right side), and the adjustment top block 1112225 can be freely accommodated in the mounting space and fixed on the adjustment plate by means of a fastener such as a screw b 11122251.

As in the present example, the upper side of the adjustment top block is substantially an arc surface (first adjustment structure), and a position of the arc surface near the middle portion extends out of the installation space of the second base plate 1112221. Wherein the stepper motor is coupled to the adjustment wedge 1112226 to urge the adjustment wedge toward/away from the adjustment top piece 1112225. The underside of the adjustment wedge 1112226 (the second adjustment structure) may be beveled, curved, or a combination of both. According to the orientation shown in the figure, as in the present embodiment, the underside of the adjusting wedge is a sloping surface sloping downward from right to left.

In one possible embodiment, for example, a stepper motor may drive the adjuster wedge 1112226 to the left via a T-screw 1112229. Preferably, a guide rail 1112228 adapted to the movement track of the adjusting wedge may be disposed on the second bottom plate 1112221, so that the stepper motor drives the adjusting wedge to move leftwards along the guide rail through the T-shaped lead screw, and as in this example, a sliding end 1112227 matched with the guide rail is disposed above the adjusting wedge. The left movement of the adjusting wedge will push the adjusting top block downward, and the adjusting plate will rotate clockwise around the positioning block 1112223 because the adjusting top block is fixed on the adjusting plate 1112222. Similarly, when the stepper motor rotates in the opposite direction, the adjustment wedge 1112226 moves to the right, the adjustment top block 1112225 moves upward, and the adjustment plate 1112222 rotates counterclockwise about the positioning block 1112223.

It will be appreciated that, on the premise of satisfying the precision, the bottom surface of the adjusting wedge may be changed to a plane, and the advancing direction of the stepper motor may be set to have a certain included angle with the second bottom plate.

Referring primarily to fig. 3 and 13, in one possible embodiment, the loading table assembly 113 basically includes a loading platform 1131, a unloading platform 1132, and two sets of drive transmission mechanisms disposed therebetween. As in the present example, the drive transmission mechanism mainly includes a loading and unloading motor 11331, a first ball screw 11332, and a first rail slider 11333, where the loading and unloading motor drives the first ball screw to move under the guidance of the first rail slider and generate displacement along the X-axis direction. The two sets of driving transmission mechanisms are respectively used for driving the feeding platform 1131 and the discharging platform 1132 to move along the X-axis direction, so that the position adjustment of the silicon rod along the X-axis direction is realized, and the feeding process and the discharging process are completed. In this example, an organ shield 11334 is disposed between the feeding platform and the discharging platform, so as to play a role in preventing water and dust under the premise of ensuring that feeding and discharging can be achieved.

In this example, a servo motor is provided at a position on the back side (rear side in the drawing) of the third bottom plate and located at a substantially middle portion, a power output shaft of the servo motor extends out of the front side of the third bottom plate and is connected with a first gear 11240, a position on the upper first rack 11241 near the left side and a position on the lower second rack 11242 near the right side are engaged with the gears 11240, respectively, and the right end of the first rack 11241 and the left end of the second rack 11242 are connected to a first clamp plate 11251 on the left side and a second clamp plate 11252 on the right side, respectively. In operation, the feeding assembly 111 conveys the silicon rod to the lower part of the centering assembly 112, and then stops moving, and the (first and second) clamping plates move from the outer side to the inner side respectively, clamp the silicon rod, and then stop moving. In order to ensure the stability of movement, the bottom plate is provided with a guide rail, the (first and second) clamping plates are provided with guide grooves matched with the guide rail, so that the servo motor rotates to drive the gear 11240 to rotate, and the (first and second) racks drive the (first and second) clamping plates to move inwards in a mode of moving on the guide rail by meshing with the gear 11240.

The (first and second) clamping plates of the centering assembly 112 allow the (movable and fixed) jaws of the feed slide apparatus 12 to reach a proper position in advance before clamping the silicon rod by adjusting the positions of the silicon rod in the Y-axis direction, and at the same time, the length of the silicon rod can be measured. The first probe 11261 and the second probe 11262 of the two first probe groups determine the adjustment amounts of the position and the angle of the silicon rod by detecting the rear side surface and the upper side surface of the silicon rod, respectively.

The configuration of the first/second clamping plates and the arrangement of the first probe set on the corresponding clamping plates will be described below by taking the second clamping plate 11252 corresponding to the right side as an example. In one possible embodiment, the second clamping plate 11252 mainly includes a clamping plate main body 112521, a first mounting plate 112522 and a second mounting plate 112523, where the clamping plate main body is used to clamp the silicon rod 2, the first mounting plate is provided with a groove 1125221 that mates with the guide rail on the aforementioned third bottom plate, the first probe 11261 is disposed on the first mounting plate, the second mounting plate 112523 is substantially parallel to the first mounting plate and is disposed at a position behind the lower side of the first mounting plate, and the second probe 11262 is disposed on the second mounting plate.

In this example, the first probe 11261 is protruded to touch the upper surface of the silicon rod 2, and then the external dimension of the silicon rod 2 is calculated according to the compression amount of the head of the first probe 11261. After the inspection is completed, it is necessary to keep the head thereof away from the upper side surface of the silicon rod 2. In order to realize the expansion and contraction of the head of the first probe 11261, for example, a second cylinder 112611 may be configured for the first probe 11261, for example, the second cylinder 112611 may be mounted on the first mounting plate to push the head of the first probe to extend, and the compression amount of the head of the first probe may be obtained after the head of the first probe contacts the surface of the silicon rod 2. The second probe 11262 is fixed to the second mounting plate 112523 without the need for a cylinder. Specifically, the second probe 11262 is compressed only by moving the silicon rod 2 in a direction approaching the second probe 11262 by the feeding device 11, and the compression amount is obtained. Namely: detection of the rear surface of the silicon rod by the second probe 11262 can be achieved with movement of the silicon rod in the X-axis direction.

Based on this, the centering assembly 112 works on the following principle: the clamping plates of the centering assembly 112 are clamped and then loosened, the feeding platform 1131 continues to advance for a certain distance along the X-axis direction, and the two second probes 11262 are compressed, so that the overall dimension (width) of the silicon rod 2 along the X-axis direction is obtained, and the width difference of the two ends of the silicon rod 2 is obtained through the pair of second probes 11262. And then the second air cylinders 112611 corresponding to the two first probes extend out to drive the heads of the two first probes 11261 to contact with the upper surface of the silicon rod and compress a distance, so that the overall dimension (height) of the silicon rod along the Z-axis direction is obtained, and the height difference of the two ends of the silicon rod is obtained through the pair of first probes 11261. And calculating the required adjustment amount of the silicon rod through the detected width difference and height difference, adjusting through the feeding device 11, and enabling the (fixed and movable) chucks to clamp the silicon rod 2 after the adjustment is finished, so as to finish the feeding.

Further, the fixed chuck 121 and the movable chuck 122 are provided with a fixed chuck rotating motor 1211 and a movable chuck rotating motor 1221, respectively, so as to rotate the silicon rod after the (fixed, movable) chucks grip the silicon rod, such as to be rotatable from one set of surfaces to be ground to the other set of surfaces to be ground.

Referring mainly to fig. 1, 16 to 18, in one possible embodiment, the grinding device 13 mainly includes a pair of rough grinding stones 131 disposed opposite to each other for rough grinding the silicon rod 2, a pair of fine grinding stones 132 disposed opposite to each other for fine grinding the silicon rod 2, and a detection unit 133. Wherein, the fine grinding wheel 132 is located at the downstream side of the rough grinding wheel 133 along the feeding direction of the silicon rod so as to perform fine grinding after rough grinding of a certain grinding surface, and the detecting component 133 is configured on the rough grinding wheel 131 and is mainly used for detecting the position of the silicon rod 2 before the grinding operation starts.

In one possible embodiment, the rough grinding motor 1311 drives the fourth ball screw 1312 to move the bracket 1314 carrying the rough grinding wheel 131 in the X-axis direction by means of the guidance of the fourth rail slider 1313. The detection unit 133 is mounted on a holder 1314 for mounting the rough grinding wheel 131. The motion of the fine grinding wheel 132 may be similar to that of the coarse grinding wheel 131, and will not be described here.

It can be seen that in the feeding device of the invention, in the first aspect, the position adjustment of the silicon rod along the Z axis is realized through the cooperation of the transmission plate, the connecting shaft and the lifting wheel in the lifting assembly. On the basis, through the eccentric shaft of the lifting wheel, the angle adjustment of the silicon rod along the X axis is realized through the lifting component. Therefore, the feeding precision corresponding to two dimensions is adjusted through the lifting assembly.

Therefore, the feeding precision corresponding to the third dimension is adjusted through the lifting assembly. In the third aspect, the driving transmission mechanism in the feeding table assembly can adjust the position of the silicon rod along the X axis in the process of moving the feeding assembly clamping the silicon rod. Therefore, the feeding precision corresponding to the fourth dimension is adjusted through the lifting assembly. In summary, based on the scheme of the invention, the four-dimensional adjustment of the silicon rod can be realized through the feeding device, and the feeding precision of the grinding machine is ensured by combining the position adjustment along the Y axis realized through the centering component and the angle adjustment along the Y axis realized through the (fixed) chuck (namely, the adjustment can be realized through the centering component when the deviation is the position along the Y axis and the rotation of the (fixed) chuck when the deviation is the angle along the Y axis).

It will be appreciated that in the present invention there may be a relationship between the loading assembly and the detection assembly, and thus, in alternative cases, the aforementioned first probe set corresponding to the centering assembly may be suitably reduced or omitted.

With the above-described structure, an embodiment of a feeding control method of a grinding machine according to the present invention will be described below with reference mainly to fig. 19.

Referring to fig. 19, fig. 19 is a flow chart illustrating a feeding control method of a grinding machine according to an embodiment of the invention. As shown in fig. 19, in one possible embodiment, the feeding control method of the grinding machine of the present invention mainly includes the following steps:

and S1901, after the feeding device performs initial adjustment on the silicon rod, the feeding sliding table device sends the silicon rod to the grinding area.

Specifically, after the loading device 11 completes the pose adjustment of the silicon rod 2, the feeding sliding table device 12 moves along the Y axis relative to the sliding table assembly after reaching a predetermined position according to the length of the silicon rod measured by the centering assembly 112, so that the silicon rod is clamped by the cooperation between the fixed chuck 121 and the movable chuck 122. After that, the feed slide device 12 moves along the Y axis, and carries the silicon rod 2 to the grinding region.

S1903, detecting the silicon rod by a detection component in the grinding device, and judging whether the state of the silicon rod meets the condition of grinding the silicon rod by the grinding component according to the detection result of the detection component; if not, the process proceeds to S1905, and if yes, the process proceeds to S1907.

The inspection assembly 133 inspects the silicon rod 2 before grinding. In one possible embodiment, the detecting unit 133 detects the silicon rod 2 by: when the silicon rod 2 stops moving after coming to the first detection position, the third cylinder 1335 of the detection assembly 133 extends to push the third probe 1334 to move along the X-axis direction, and the position of the third probe 1334 is advanced relative to the grinding wheel. Then, the rough grinding wheel 131 and the inspection unit 133 continue to move in the X-axis direction by the driving of the rough grinding motor 1311 until the third probe contacts the silicon rod and the inspection is completed (dotting is not ground). Along with the movement of the silicon rod along the Y-axis direction, the third probe can detect the knife-in position of the silicon rod, the middle position along the length of the rod and the knife-out position of the silicon rod in sequence, and then the chuck drives the silicon rod to rotate by 90 degrees, so that the detection process is repeated.

The judgment result of judging that the state of the silicon rod does not satisfy the condition for the grinding assembly to grind it by the detection result of the detection assembly 133 specifically includes: 1) If the maximum grinding size of the silicon rod is smaller than the standard size after grinding, the rod size is judged to be unqualified and cannot be ground, and the silicon rod can be retracted to a blanking platform (rod withdrawing). 2) On the premise that the silicon rod is qualified, the position deviation and the angle deviation between the axis of the (fixed and movable) chuck and the axis of the silicon rod can be measured by measuring the three positions of the silicon through the second probe group, and if the deviation is larger than a specified value, the state of the silicon rod is considered to not meet the condition that the grinding assembly grinds the silicon rod. The case where the condition is not satisfied mainly includes two kinds: 21 The angle of the silicon rod along the Y axis has deviation, and the silicon rod can be adjusted by rotating the clamping head (fixed and movable); 22 If the silicon rod has a deviation in position/angle along the (X, Z) axis, this is the case in the present discussion, and the process proceeds to S1905.

S1905, enabling the silicon rod to be placed on a feeding platform of the feeding device in a connecting mode (without manual intervention), and adjusting the state of the silicon rod through the feeding device.

Specifically, the silicon rod is directly reset on a loading platform of the loading device, and the pose of the silicon rod is secondarily adjusted on the loading platform. As described above, the position state of the silicon rod along the Z axis and the angle state of the silicon rod along the X axis can be adjusted through the lifting assembly, the angle state of the silicon rod along the Z axis can be adjusted through the adjusting assembly, and the position state of the silicon rod along the X axis can be adjusted through the driving transmission mechanism of the feeding table assembly.

After the adjustment is completed, the process returns to S1903 to re-detect until the detection is completed and the condition for grinding the grinding component is satisfied, and the process proceeds to S1907.

And S1907, enabling the grinding assembly to grind the silicon rod.

Specifically, the grinding assembly mainly includes a rough grinding wheel and a fine grinding wheel, and the grinding amount of the rough grinding wheel 131 can be calculated in the foregoing detection process, and the rough grinding wheel advances a certain distance toward the X-axis according to the grinding amount, thereby performing rough grinding. After the rough grinding is finished, the detection assembly repeats the previous detection process, the grinding amount of the fine grinding wheel 132 is calculated, and the fine grinding wheel is advanced to the X axis by a certain distance according to the grinding amount, so that fine grinding is performed.

And S1909, finishing grinding and blanking.

After finishing grinding, the feeding sliding table device returns to the blanking area of the feeding device, and at the moment, the (fixed and movable) chucks loosen the silicon rod, so that the silicon rod falls to a blanking table corresponding to the blanking area, and blanking is finished.

According to the feeding control method of the grinding machine, according to the detection result of the detection component, the feeding precision of the grinding machine is ensured by directly resetting the feeding device to adjust the pose of the silicon rod. The person skilled in the art can adopt the structure same as or different from the structure to realize the precision adjustment of the corresponding dimension according to the actual requirement.

It should be noted that, although the steps are described in the above embodiments in a specific order, it will be understood by those skilled in the art that, in order to achieve the effects of the present invention, the steps are not necessarily performed in such an order, and may be performed simultaneously or in other orders, or some steps may be added, replaced, or omitted. The method can be as follows: the specific switching mode between coarse grinding and fine grinding can be adjusted according to actual conditions; on the premise that the silicon rod does not meet the grinding condition, the silicon rod is directly placed in the feeding device again, only one part of the silicon rod (the four dimensions (main) and the position adjustment along the Y axis corresponding to the centering component) is adjusted, and the other part of the silicon rod is realized by the rotation between the (fixed and movable) chucks in the feeding sliding table device, namely, the sequence can be set according to the actual situation on the premise that the angle state along the Y axis is required to be adjusted and the state of the four dimensions is required to be adjusted through the feeding device; etc.

It should be noted that, although the feeding control method of the grinding machine configured in the above-described specific manner is described as an example, those skilled in the art will understand that the present invention should not be limited thereto. In fact, the user can flexibly adjust the relevant steps and parameters in the steps according to situations such as actual application scenes, for example, when the clamping assembly, the lifting assembly and the centering assembly realize four-dimensional adjustment, the four adjustments can be performed simultaneously or sequentially, and the like.

Thus far, the technical solution of the present invention has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present invention is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present invention, and such modifications and substitutions will fall within the scope of the present invention.
