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

The grinding machine is equipment for grinding hard and brittle materials. Such as grinding machines, typically include a loading assembly, a feeding assembly, and a grinding assembly. Taking a piece made of hard and brittle materials as a silicon rod as an example, firstly fixing the cut silicon rod to a feeding assembly, performing certain initial adjustment on the position and posture of the feeding assembly, and then conveying the silicon rod to a position between two chucks of the feeding assembly, wherein for example, the two chucks can be both movable chucks or one chuck is a movable chuck and the other chuck is a fixed chuck. And the silicon rod is conveyed to the grinding assembly through the axial movement of the silicon rod, so that the first group of surfaces to be ground are subjected to grinding processing including rough grinding and fine grinding. Thereafter, the silicon rod is rotated to a second group of surfaces to be ground by rotating the silicon rod, and on this basis, the second group of surfaces to be ground is subjected to grinding work including rough grinding and finish grinding. And repeating the steps until all surfaces to be ground of the silicon rod are ground according to the set grinding standard.

Taking the hard and brittle material as an example of the silicon rod, since the specifications of the silicon rods are different and the external dimensions of the silicon rods of the same specification are different, when the silicon rods are placed on the loading platform, a certain position deviation usually exists between the axis of the silicon rod and the axes of the 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 expressed as the feeding precision of the silicon rod on the grinding machine. The unqualified position deviation and angle deviation can affect the feeding precision of the silicon rod, and the reduction of the feeding precision can be generally expressed as the increase of the grinding quantity of the silicon rod and the improvement of silicon loss in different degrees, so that the processing efficiency of a grinding machine is reduced, and the surface quality of the silicon rod is reduced.

Disclosure of Invention

The present invention is intended to solve at least part of the above-described problems, and more specifically, to suppress or eliminate any of the positional deviation and the angular deviation, therefore, the feeding precision of the silicon rod is improved on the basis, and the processing efficiency of the grinding machine and the surface quality of the silicon rod are further improved.

In a first aspect, the present invention provides a loading apparatus comprising: 1) Material loading subassembly, it includes: 11 A lifting assembly including a pallet on which a workpiece to be processed can be set, the lifting assembly being capable of lifting the workpiece to be processed set on the pallet in a vertical direction and allowing different portions of the workpiece to be processed to be lifted at different heights; 12 Clamping assembly comprising a clamping first end assembly, a clamping second end assembly and an adjustment assembly arranged on said clamping first end assembly and/or said clamping second end assembly, said adjustment assembly being capable of varying the distance between different parts of the piece to be machined and the respective clamping first end assembly and/or said clamping second end assembly.

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

Compared with the mode of carrying out manual participation after the workpiece to be processed is directly discharged (rod withdrawing), the invention directly places the workpiece to be processed in the feeding device for readjustment, thereby improving the adjustment efficiency. Compared with the mode of adjusting through a (fixed or movable) chuck in the feeding direction, the feeding device has the advantages that due to the fact that the number of parts involved in the structure of the feeding device is relatively large, feeding precision adjustment in four dimensions can be achieved through different parts. In addition, because the feeding device and the (fixed and movable) chuck are structurally separated, the adjustment of corresponding dimensions is easier to realize by means of adding parts and the like.

Particularly, through the arrangement of the lifting assembly, the lifting assembly is arranged on the supporting plate to realize lifting in the height direction, and meanwhile, fine adjustment of different parts of the workpiece to be processed on the lifting height can be realized. Through the setting of centre gripping subassembly, will treat that the machined part is tight when pressing from both sides tightly, can also realize treating the fine setting of the different parts of machined part on the clamping position. The adjustment involved in the present invention 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 can be understood that, according to actual requirements, a person skilled in the art can determine the structural form of the lifting assembly and the implementation manner of the structural form to implement the two-dimensional adjustment of the to-be-processed member disposed on the supporting plate. By way of example, it is assumed that the lifting assembly comprises a mechanism 1 and a mechanism 2, wherein the mechanism 1 can achieve height adjustment and the mechanism 2 can achieve height deviation adjustment. Such as may be: the

units

1 and 2 can be operated independently of one another, so that the height adjustment and the height deviation adjustment can be carried out without interference in space-time (e.g., simultaneously or in any desired sequence); the mechanism 1 and the mechanism 2 have a cooperative relationship in movement such that the height adjustment and the height deviation adjustment are achieved simultaneously or in a specific order (e.g., height adjustment followed by height deviation adjustment); and the like.

Obviously, the mechanism 1 and the mechanism 2 may be in any form as long as it is ensured that the workpiece to be processed can be lifted and deviations in the lifting height can occur. For example, the

mechanisms

1 and 2 may be independent mechanisms or have associated mechanisms (e.g., some structural coincidence therebetween, one being part of the other, the two being connected by an intermediate member, etc.).

It can be understood that, a person skilled in the art may determine the structural form of the adjustment assembly and the configuration thereof in the clamping first end assembly and/or the clamping second end assembly and the specific configuration position according to actual requirements, wherein the clamping second end assembly and the clamping first end assembly may be both movable ends or one fixed end and one movable end. Illustratively, an adjustment assembly is disposed on each of the clamped first end assembly and the clamped second end assembly. The adjusting component can be a structure additionally arranged on the first end clamping component and the second end clamping component, or a structure formed by mutually combining with a part of the existing structures for clamping the first end clamping component and the second end clamping component. The adjustment assembly is, for example, a separate structure, and the angular adjustment of the workpiece along the Z-axis is performed in such a way that different parts of the workpiece are at different distances from the corresponding 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 arranged outside the first end clamping assembly and the second end clamping assembly, and the distances between different parts of the workpiece to be processed and the corresponding first end clamping assembly and/or second end clamping assembly are different in a mode of 'the mechanism 3 can push one end of the first end clamping assembly to displace in a first direction (along the length direction of the workpiece to be processed) and the mechanism 4 can push the other end of the second end clamping assembly to displace in the opposite direction of the first direction', so that the angle adjustment of the workpiece to be processed along the Z axis is realized.

With regard to the above feeding device, in one possible embodiment, the feeding device further includes: 2) The feeding platform assembly comprises a feeding platform, a discharging platform and a driving transmission mechanism, wherein the driving transmission mechanism drives the feeding assembly carrying the workpieces to be processed to move along the direction between the feeding platform and the discharging platform, and therefore the workpieces to be processed are adjusted to move along the direction of movement.

With such a configuration, it is possible to increase the feed height of the workpiece to be processed in the third dimension in addition to the three dimensions described above.

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

It can be understood that, in order to ensure that the precision 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 the loading device, in one possible embodiment, the lifting assembly comprises: a first drive member; a lifting wheel set comprising a plurality of lifting wheels, the first drive member in driving connection with the lifting wheels, the lifting wheels in operative connection with the pallet; the first driving part can drive the lifting wheel to rotate so as to lift the supporting plate and a to-be-processed workpiece arranged on the supporting plate; the lift assembly further comprises: an adjustment portion in signal connection with at least the lift wheel to: the lifting heights of the supporting plate corresponding to the positions of the plurality of lifting wheels are different.

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

It should be noted that the drive connection in "the first drive member is in drive connection with the elevator wheel" is to be understood as: when the first driving component sends out a driving action, the lifting wheel can concomitantly generate an action related to the driving action, namely the lifting wheel can generate actions such as lifting and the like in response to the driving of the first driving component. For example, the first driving part and the lifting wheel can be in direct driving connection or indirect driving connection.

It should be noted that the operative connection in the "operative connection of the lifting wheel to the pallet" is understood to mean: when one of the lifting wheel and the pallet is acted, the other one can concomitantly produce the action associated with the action, i.e. the two have an association at the operational level, e.g. the two can be a direct association or an indirect association.

It should be noted that the signal connection in "the adjustment portion, which is at least in signal connection with the lifting wheel" should be understood as: according to different control instructions of the adjusting part, the lifting wheel can generate a lifting height corresponding to the instructions. It is obvious that a person skilled in the art can make a mapping relationship between the control command and the lifting height according to actual requirements. Alternatively, based on such signal connection, the mapping relationship between the control command and the lifting height may be flexibly selected according to actual requirements, and the map may be known, conventionally selected, or flexibly configured according to actual situations, and the like.

It is understood that the structural form, the number, the relative position between each lifting wheel (in the case that the lifting wheels include a plurality of lifting wheels) and the relative position between the lifting wheels and the supporting plate can be determined by those skilled in the art according to actual needs. Such as may be: the lifting wheels comprise two groups, and the two groups of lifting wheels are arranged at positions close to two ends of the silicon rod; the lifting wheels comprise four lifting wheels which are respectively marked as A, B, C, D, wherein A and C are one group, the silicon rods arranged on the supporting plate can realize the first type of lifting by means of the lifting wheels (A, C), wherein B and D are one group, and the silicon rods arranged on the supporting plate can realize the second type of lifting by means of the lifting wheels (B, D); and the like.

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

It is understood that the direction of the displacement of the lifting wheel driven by the first driving member and the displacement amount can be determined by those skilled in the art according to actual needs. For example, the displacement may be in a direction including only the height direction, or may be in other directions including but not limited to the horizontal direction. For the displacement amount, a person skilled in the art can set how the driving component can cause the lifting wheel to generate the expected displacement amount according to a driving mode of the lifting wheel driven by the first driving component to generate the displacement, a displacement amount required by the workpiece to be processed, and the like.

It can be understood that a person skilled in the art can determine the specific structural form of the supporting plate according to actual requirements, such as directly arranging the supporting plate or adding a corresponding functional structure on the supporting plate and then arranging the workpiece to be processed on the functional structure.

With regard to the above-mentioned loading device, in a possible embodiment, a part of the plurality of lifting wheels is fixedly connected to the pallet in a rotatable manner, the lifting assembly further comprising a transmission member connected to the first driving member on the one hand and interfacing with the lifting wheels on the other hand, wherein the transmission member has an inclined guide surface in a position close to the lifting wheels such that: when the first driving component drives the transmission component to transversely move, the lifting wheels rotate along the guide surface and lift the supporting plate and the workpiece to be machined arranged on the supporting plate; another part of the plurality of lifting wheels is provided with an eccentric shaft, which is provided with a second drive means, 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 supporting plate and different parts of the workpiece to be machined, which are arranged on the supporting plate, are allowed to be lifted at different heights.

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

It should be noted that the rotation in the "a part of the plurality of lifting wheels is fixedly connected to the supporting plate in a rotatable manner" should be understood as the rotating property of the lifting wheels, and the fixed connection should be understood as the connection relationship between the lifting wheels and the supporting plate. Illustratively, the lifting wheel is provided with a shaft, the shaft is fixedly connected to the supporting plate, and the lifting wheel can rotate around the shaft. Illustratively, the pallet is a generally housing structure, the workpiece to be processed is fixed to the top of the housing structure, and the elevator wheels are mounted on the sides of the housing structure through wheel shafts.

It is understood that the structural form, the number of the transmission components and the specific motion form generated by the first driving component can be determined by those skilled in the art according to actual requirements. For example, the transmission component may be a plate-shaped structure, a block-shaped structure, a strip-shaped structure, etc., and the movable form of the transmission component may include movement, rotation, a combination of the two, etc. For example, the lifting wheels may share one transmission member, each lifting wheel may be provided with a plurality of transmission members, and the lifting wheels may correspond to the transmission members one by one.

A guide surface as inclined is to be understood here as: the height of the downstream side of the guide surface should be lower than the height of the upstream side of the guide surface, as seen in the traversing direction of the transmission member. The guide surface having such a characteristic may be a slant surface, a (concave, convex) curved surface, a combination thereof, or the like. The first driving part is taken as a power cylinder, the guide surface is taken as an inclined surface as an example, the transmission part moves transversely along with the extension of a 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 of the lifting wheel on the inclined surface, so that the supporting plate can be driven to generate displacement along the vertical direction, and the lifting of the workpiece to be processed is realized. For example, 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 part can be directly connected with 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 transmission member through a transmission mechanism such as a lead screw nut pair to effect the lateral movement of the transmission member. Since the second driving member is mainly used for driving the eccentric shaft to rotate, the second driving member is usually a motor.

The lifting height among the lifting wheels is different under the action of the transmission component, so that the lifting height of different positions of the part to be machined is different.

It will be understood that a person skilled in the art can determine the specific specification of the eccentric shafts and the specific number and positions of the eccentric shafts configured in the lifting wheel according to actual requirements, and the like, and the lifting wheel exemplarily includes two lifting wheels, one of which is a common shaft and the other is an eccentric shaft.

With regard to the above feeding device, in a possible embodiment, the lifting assembly includes a constraining component, and the supporting plate generates displacement along the height direction under the cooperation of the constraining component, and thus lifts the supporting plate and the workpiece to be processed arranged on the supporting plate along the 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 should be understood that the structural form, the number of the guide and limit stop members, the relationship between the guide and limit stop members and the supporting plate, etc. can be determined by those skilled in the art according to actual requirements. Such as may be: the guide limiting component comprises a baffle plate/a baffle rib arranged outside the supporting plate in a surrounding mode, a guide rail matched with the supporting plate and the like.

In a possible embodiment, the constraint component is a connecting shaft, and the supporting plate is provided with a hole, and the connecting shaft is freely accommodated in the hole.

By such a constitution, a specific configuration of the restricting member is given.

With regard to the above feeding device, in a possible implementation manner, the supporting plate includes a first bottom plate, the lifting assembly includes a return spring, and the return spring is disposed between the first bottom plate of the lifting assembly and the supporting plate.

Particularly, through the setting of reset spring, guaranteed that the layer board can return reliably. For example, in the process that a power output shaft (piston) of the power cylinder extends out and a supporting plate is lifted, the return spring is in a stretched state. When the power output shaft of the power cylinder retracts, the supporting plate descends under the combined action of the pulling force of the reset spring and the self gravity of the supporting plate, and therefore the supporting plate is reset.

It is understood that the specification (such as elastic coefficient, etc.) of the return spring, the number of the arrangement, the arrangement position and the specific connection mode with the bottom plate and the supporting plate, etc. can be determined by those skilled in the art according to actual requirements. Illustratively, taking the constraining member as the shaft, the return spring, for example, comprises a plurality of springs distributed around the circumference of the shaft. In addition, a return spring can also be sleeved outside the connecting shaft.

For the loading device, in one possible embodiment, the adjustment assembly comprises: the clamping first end component and/or the clamping second end component are/is movably arranged on the second bottom plate; a third drive member operatively connected to the respective clamping first end assembly or the clamping second end assembly to: the distance between the clamping first end assembly or the clamping second end assembly and different parts of the second base plate is different under the driving of the third driving part.

Through the structure, a specific implementation mode of realizing one-dimensional feeding precision adjustment of the adjusting assembly is provided. Particularly, fine adjustment of the angle of the silicon rod to be ground waiting for a workpiece can be realized along the feeding/clamping direction.

It should be noted that the operative connection of the "third driving member operatively connected to the respective clamping first end assembly and/or clamping second end assembly" is understood to mean: when the third driving member acts with one of the respective clamping first end assembly and clamping second end assembly, the other concomitantly acts in association with the action, i.e. both have an association in the operational level, e.g. the third driving member may be in direct drive connection or in indirect drive connection with the clamping first/second end assembly.

It will be appreciated that the second base plate may be directly or indirectly connected to the first/second end member, and that the difference in distance between the different parts may be achieved by rotation, movement or a combination thereof. Such as may be: the displacement of the second bottom plate and the clamping first/second end component 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 component are different; the second bottom plate and the first/second bottom plate can rotate on one hand and move along the thickness direction (clamping direction) on the other hand, and different local distances between the second bottom plate and the first/second bottom plate are different through two movement amounts; and the like.

It will be appreciated that one skilled in the art may configure the adjustment assembly for clamping the first/second end assembly according to actual needs. For example, if the mounting position for holding the first end assembly is assumed to be relatively fixed, configuring the adjustment assembly for holding the first end assembly may effectively prevent the adjustment amount of the adjustment assembly from interfering with other movements.

For the above feeding device, in a possible implementation manner, the second bottom plate is reserved with an installation space, and the adjusting assembly includes: the first adjusting component is arranged on the clamping plate for clamping the first end assembly and/or the second end assembly, is freely accommodated in the mounting space and is provided with a first adjusting structure extending out of the mounting space; a second adjustment member drivingly connected to the third drive member and having a second adjustment structure inclined at a side thereof adjacent the first adjustment member such that: when the third driving component drives the second adjusting component to move towards the direction close to the first adjusting component, the second adjusting structure presses against the first adjusting structure so as to drive the clamping plate and the second bottom plate to rotate relatively, and therefore the 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, the difference in distance from different parts of the clamping plate and the second base plate is achieved by means of cooperation with the first adjustment structure and the second adjustment structure.

It is understood that a person skilled in the art can flexibly select the structural form of the first/second adjusting component, the specific structural form of the first/second adjusting structure, the arrangement position, arrangement mode, etc. of the first/second adjusting structure on the first/second adjusting component according to actual requirements.

If the first/second adjusting structure is fixedly connected or integrally formed on the first/second adjusting member, the cross section of the first adjusting structure (in the thickness direction of the second base plate) may be a curved surface, an inclined surface, or the like. Illustratively, the first adjusting component and the first adjusting structure are integrally formed and are approximately cylindrical blocks with cambered ends.

The inclination as in the "inclined second adjustment structure" should be understood as: the height of the downstream side of the second regulating structure should be lower than the height of the upstream side, as viewed in a direction away from the first regulating member toward the first regulating member. The second adjustment structure having such a feature may be a slant surface, a (concave, convex) curved surface, a combination thereof, or the like. Illustratively, the second adjustment member is integrally formed with the second adjustment structure and is generally wedge-shaped.

With regard to the above-described feeding device, in one possible embodiment, the first adjusting component is an adjusting top block and/or the second adjusting component is an adjusting wedge block.

With this configuration, a specific configuration of the first/second regulating member is given.

With regard to the above-mentioned feeding device, in one possible embodiment, the adjusting assembly comprises: the adjusting plate is arranged between the second base plate and the clamping plate, wherein the second base 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 given.

In particular, since the clamping plate has stringent specifications both in terms of precision and functionality, and furthermore, as corresponds to the clamping plate assuming clamping of the first/second end assembly, is a movable component, it may also cooperate with other components. Therefore, through the arrangement of the adjusting plate, the influence of the realization of the adjusting function of the clamping device on the basic clamping performance of the original clamping assembly can be avoided.

In a possible embodiment, the adjusting plate is fixedly connected to the clamping plate or is integrally formed with the clamping plate.

It will be appreciated that the specific manner of attachment of the adjustment plate to the first adjustment member and the clamping plate may be determined by those skilled in the art based on actual requirements. Such as screwing, clamping, bonding, etc.

With regard to the above-mentioned feeding device, in one possible embodiment, the adjusting assembly comprises: a positioning member fixedly provided to the second base plate; and the adjusting plate is provided with a reserved space at a position corresponding to the positioning component; wherein a portion of the positioning member in the headspace has a gap with the headspace such that: the clamping plate and the second bottom plate are relatively rotated through the movement of the positioning component in the reserved space.

By such a construction, a specific manner of connection between the adjusting plate and the base plate is given.

In the case where 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 for the adjusting plate. Therefore, in order to ensure the rotation, the setting position of the reserved space corresponding to the positioning block and the setting position of the installation space corresponding to the first adjusting member on the adjusting plate should have a certain distance.

With regard to the above-mentioned feeding device, in one possible embodiment, the adjusting assembly comprises: the positioning component is a positioning block.

By such a construction, a specific form of construction of the positioning member is given.

With regard to the above feeding device, in a possible embodiment, the position of the supporting plate near the middle of one side of the workpiece to be processed is a concave structure far away from the workpiece to be processed, as viewed along the length direction of the workpiece to be processed.

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

With regard to the above feeding device, in a possible implementation manner, the supporting plate comprises a supporting plate main body and a supporting plate, and the workpiece to be processed is arranged in the supporting plate, wherein the supporting plate is recessed towards the direction away from the workpiece to be processed at a position close to the middle part of one side close to the workpiece to be processed.

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

With regard to the feeding device, in a possible embodiment, viewed along the length direction of the workpiece to be processed, the support plates include two groups which are separately arranged, each group of the support plates includes at least one support plate, and a structure which is concave in the direction away from the workpiece to be processed is formed between the two groups of the support plates; or the support plate is of an integrally formed structure, and a structure which is sunken towards the direction away from the workpiece to be machined is formed at the position, close to the middle part, of the support plate.

By such a construction, a possible way of forming the recesses in the carrier is given.

In a second aspect, the invention provides a grinding machine comprising a charging device as defined in any one of the preceding claims.

It can be understood that the grinding machine has all the technical effects of the feeding device described in any one of the foregoing, and the details are not repeated herein.

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

By such a constitution, a specific form of the member to be worked is given.

In a third aspect, the present invention provides a material loading control method for a grinding machine, the grinding machine including a material loading 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 for grinding the workpiece by the grinding assembly according to the detection result of the detection assembly; if not, selectively placing the workpiece to be processed on the feeding device, and adjusting at least part of the state of the workpiece to be processed through the feeding device, wherein the step comprises the following steps: the position state of the workpiece to be processed along the vertical direction is adjusted through the first adjusting part; the position states of different parts of the workpiece to be processed along the vertical direction are adjusted through the second adjusting part; the position states of different parts of the workpiece to be processed along the feeding and discharging direction are adjusted through the third adjusting part; the position state of the workpiece to be processed along the feeding and discharging direction is adjusted through the fourth adjusting portion.

Through the structure, the workpiece to be machined can be adjusted in four dimensions in the feeding link, so that the workpiece to be machined can be in a state meeting grinding conditions, for example, the workpiece to be machined is a silicon rod.

It will be appreciated that the base unit may adopt all possible connections provided that it has the base unit described above and that it is ensured that the control method is implemented. In other words, this solution obviously has all the technical effects of any one of the aforementioned lifting assemblies, and is not described herein again.

Compared with the mode of carrying out manual participation after the workpiece to be processed is directly discharged (rod withdrawing), the invention directly places the workpiece to be processed in the feeding device for re (repeated) adjustment, 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) clamping heads, the feeding precision adjustment in four dimensions can be realized by different components due to the relatively large number of components involved in the structure of the feeding device. In addition, because the feeding device and the (fixed and movable) chuck are structurally separated, the adjustment of corresponding dimensions is easier to realize by means of adding parts and the like.

It should be noted that "selectively placing the workpiece to be processed on the feeding device" should be understood as follows: the condition that the state of the workpiece to be machined does not satisfy the condition that the grinding assembly grinds the workpiece may include that a rod needs to be directly withdrawn, that readjustment is needed but the feeding device cannot achieve such adjustment, that readjustment is needed and that adjustment can be achieved by the feeding device (only by the feeding device or cooperation of the feeding device with other devices, etc.), and the like. Therefore, it is only in an effective control to place the piece to be machined on the feeding device in a situation where "readjustment is required and adjustment can be achieved by the feeding device".

With regard to the above feeding control method, in a 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 driven to rotate by the first driving part, so that the supporting plate is lifted and 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.

With such a configuration, a specific configuration of the first adjustment portion and a specific manner in which adjustment of the first dimension (hereinafter, position adjustment along the Z axis) is achieved are given.

With regard to the above feeding control method, in a possible embodiment, the lifting assembly further includes a transmission member having an inclined guide surface at a position close to the lifting wheel, and accordingly, the "driving the lifting wheel to rotate by the first driving member to lift the pallet and the member to be processed provided on the pallet" includes: when the first driving component drives the transmission component to transversely move, the lifting wheels rotate along the guide surface and accordingly lift the supporting plate and the workpiece to be machined arranged on the supporting plate.

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

Referring mainly to fig. 1, in a possible embodiment, the main body of the grinding machine 1 mainly includes a base 101 and a vertical frame 102 disposed at the bottom, and the base 101 has a certain horizontal adjustment function, so as to provide a mounting surface with a high level for the structures of the loading device 11, the grinding device 13, and the like of the grinding machine 1. Wherein, the top of the vertical frame 102 is provided with a guide rail on which the feeding slide table device 12 is mounted. The grinding machine is mainly used for grinding the silicon rod 2 after being cut as a workpiece to be machined to a set specification. Specifically, in an ideal state, the silicon rod 2 after being opened is generally a rectangular parallelepiped having the same width and height. In practice, however, the surface of the opened silicon rod 2 is not flat, as is usually the case: the middle part of the silicon rod is convex compared with the two end parts, and the size of the silicon rod knife outlet is larger than that of the knife inlet (the side length of the square of the cut end surface of the diamond wire is larger than that of the square of the cut end surface of the diamond wire). Therefore, the cut silicon rod needs to be ground to an ideal rectangular parallelepiped of a standard specification by a grinding machine.

Referring mainly to fig. 2 and 3, in one possible embodiment, the loading device 11 is mainly used for clamping the silicon rod 2 by the fixed chuck 121 and the movable chuck 122 of the feeding slide unit 12 after the silicon rod is adjusted to a proper position and angle. In order to reduce the grinding amount, reduce the silicon loss and improve the grinding efficiency, the grinding machine 1 needs a high feeding precision. In case the feeding accuracy is up to standard, the ideal axis of the silicon rod 2 and the axis between the (stationary, movable) chucks should have a high coaxiality. The invention mainly enables the coaxiality to reach a more ideal level through the adjustment of the feeding device.

In one possible embodiment, the feeding device 11 mainly comprises a feeding assembly 111, a centering assembly 112 and a feeding table assembly 113. Wherein the feeding assembly 111 and the feeding table assembly 113 require adjustment of the position and posture (hereinafter referred to as the attitude) of the silicon rod 2 in the aforementioned four dimensions, the centering assembly 112 is used to mainly determine the amount of adjustment of the attitude of the silicon rod 2 by the feeding assembly 111. Specifically, loading assembly 111 generally includes a lift assembly 1111 and a clamp assembly 1112. According to the detection result of the centering assembly 112, the lifting assembly 1111 is mainly used for performing position adjustment along the Z-axis and angular adjustment along the X-axis (rotation in a vertical plane) on the silicon rod 2, and the clamping assembly 1112 is mainly used for performing angular adjustment along the Z-axis (rotation in a horizontal plane) on the silicon rod 2. The feeding table assembly 113 is mainly used for adjusting the position of the silicon rod along the X axis in the process of moving the feeding assembly 111 holding the silicon rod 2 to the centering assembly 112. Based on this, after the feeding assembly 111 completes the adjustment of the silicon rod in four dimensions, the silicon rod with the (fixed, movable) chuck clamping pose reaching the standard is made, and the feeding process is completed.

Referring mainly to fig. 4 to 7, in one possible embodiment, the lifting assembly 1111 mainly includes a first bottom plate 11111, an electric cylinder 11112 (first driving means), a driving plate 11113 as a driving means, a lifting wheel set including a first lifting wheel 111141 (e.g., the first lifting wheel includes two wheel units disposed on a first wheel axle 111191) and a second lifting wheel 111142, and a support plate 11115, wherein the driving plate 13 has inclined surfaces 3926 zxft 11126 inclined downward from left to right as guide surfaces at positions corresponding to the first lifting wheel 111141 and the second lifting wheel 111142, respectively.

In this example, the power output shaft of the electric cylinder 11112 and the transmission plate 11113 are connected in the following manner: the first bottom plate 11111 is provided with a connecting block 11116 as a connecting component, the connecting block 11116 is fixedly connected with a transmission plate 11113 above the first bottom plate 11111 by means of a fastener such as a screw, and the like, the lower part of the connecting block 11116 is provided with a protruding end, correspondingly, an annular groove matched with the protruding end is arranged on the power output shaft of the electric cylinder 11112, and the connecting block 11116 is connected with the electric cylinder 11112 by the matching of the protruding end and the annular groove.

Thus, when the power output shaft of the electric cylinder 11112 extends rightward, the driving plate 11113 disposed at the bottom of the housing is driven to move rightward synchronously. In addition, the two lifting wheels mounted on the supporting plate 11115 can roll along the inclined plane 111131 from right to left, i.e. from low to high, and the supporting plate can be driven to move in the vertical direction along with the rolling. In this way, the position of the silicon rod set on the support plate 11115 along the Z axis is adjusted. Similarly, the power output shaft of the electric cylinder 11112 retracts, the transmission plate 11113 moves leftwards, the lifting wheel rolls from high to low, and the supporting plate 11115 descends. For example, in order to better guide the movement of the driving plate 11113, a sliding rail adapted to the movement track of the driving plate 11113 may be provided on the first bottom plate 11111.

As described above, one of the expressions that the surface of the silicon rod 2 after the cutting is not flat is: the middle portion of the silicon rod is convex compared to the two end portions. In order to enable a silicon rod having this property to be placed on the support plate more smoothly, the middle portion of the support plate is recessed farther away from the silicon rod than both sides, i.e., downward in the drawing.

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

It can be understood that, a person skilled in the art can flexibly adjust the manner of forming the recess in the pallet according to actual requirements, for example, two segments of separately arranged support plates can be integrally arranged, then the middle portion of the support plates can be integrally arranged to be the recess, and the support plates and the pallet body can be integrally arranged.

In one possible embodiment, the first base plate 11111 is provided with a connecting shaft 1117 engaged with the support plate 11115, and a return spring 1118 is further provided between the first base plate and the support plate. By the arrangement of the connecting shaft 1117, the movement of the supporting plate 11115 in the X-axis and Y-axis directions is restricted, so that the supporting plate 11115 can move only in the Z-axis direction under the guidance of the connecting shaft. When the electric cylinder 11112 is extended and the pallet 11115 is raised, the return spring 1118 is in a compressed/extended (e.g., compressed in this example) state. When the electric cylinder 11112 retracts, the supporting plate 11115 descends under the action of the elastic force of the return spring 1118 and the self-gravity of the supporting plate 11115, so that the supporting plate 11115 is reset. As in this example, a hole is opened in the pallet, and the connecting shaft is freely received in the hole so that the pallet can be smoothly raised (raised)/lowered (returned) in the axial direction of the connecting shaft. The bottom end of the connecting shaft is fixedly connected with the first bottom plate or integrally formed, the top end of the connecting shaft is provided with a radial size larger than the hole, and the axial size of the connecting shaft can ensure the lifting amount required by the silicon rod.

As in this example, the pallet body of the pallet is substantially an open-bottomed enclosure structure, the aforementioned support plate is provided on the top of the enclosure structure, and the elevating wheels are provided on the side of the enclosure structure. Illustratively, the two lift wheels are mounted to the pallet 11115 in the manner of: first lift wheel 111141 and second lift wheel 111142 are mounted to the sides of the enclosure structure through first axle 111191 and second axle 111192, respectively. When the electric cylinder 11112 extends/retracts, the supporting plate 11115 realizes the lifting/resetting of the supporting plate 11115 along with the rotation of the two lifting wheels and the rolling of the two lifting wheels on the inclined surface 111131. Based on this, the function of the lifting component 1111 may be improved, and specifically, the lifting component may have a function of adjusting the position adjustment of the silicon rod along the Z axis, and may also have a function of adjusting the angle adjustment of the silicon rod along the X axis.

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

In one possible embodiment, one of the first wheel axle 111191 and the second wheel axle 111192 may be modified to an eccentric shaft (also labeled 111191), such as in the present example, the first wheel axle 111191 corresponding to the first lift wheel 111141 is modified to an eccentric shaft, and the eccentric shaft is configured with the first adjustment motor 1111911, such as the first adjustment motor (second drive member) is connected to the eccentric shaft by a reducer-coupling. In this way, when the first adjustment motor drives the eccentric shaft corresponding to the first lifting wheel to rotate by a certain angle, the first lifting wheel 111141 installed on the eccentric shaft will lift/descend by a certain distance, and at this time, because a height difference occurs between the two lifting wheels, the supporting plate 11115 will rotate by a certain angle around the X axis, thereby realizing the angle adjustment of the silicon rod along the X axis. In accordance with this, the joint bearing 11171 is mounted on the connecting shaft 1117, so that the connecting shaft is provided to restrict the movement of the supporting plate 11115 only in the X-axis and Y-axis directions, and not to restrict the rotation of the supporting plate 11115 about the X-axis. In an actual product, for example, a mounting position corresponding to the first adjustment motor may be provided at each of positions corresponding to the first lifting wheel 111141 and the second lifting wheel 111142, and in this example, a removable closing plate 1111921 may be provided at a position corresponding to the second lifting wheel 111142. By removing the sealing plate, the first adjustment motor can be replaced to a position corresponding to the second lifting wheel 111142.

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

Referring mainly to fig. 8 to 12, in one possible embodiment, the clamping assembly 1112 mainly includes a clamping movable end assembly 11121 and a clamping fixed end assembly 11122, and the silicon rod 2 on the reference surface a of the support plate 11115 can be clamped in the X-axis direction by clamping the movable end assembly 11121 relative to the clamping fixed end assembly 11122. 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, and for example, both the clamping movable end assembly and the clamping fixed end assembly may be configured to be movable.

In one possible embodiment, the clamping movable end assembly 11121 mainly comprises 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 datum surface a of the lifting assembly 1111, the first cylinder 111211 is extended, and the slider of the X-axis guide rail slider 111212 can slide on the guide rail by pushing the bottom plate of the clamping movable end assembly 11121 so as to push the movable clamping plate 111215 to move towards 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 slides on the guide rail, so that the two movable end return springs 111214 arranged along the Y axis direction are respectively in a compression state and a tension state. After the (fixed and movable) chuck clamps the silicon rod, the first air cylinder 111211 retracts, and meanwhile, the two movable end return springs 111214 recover to return the movable clamping plate 111215.

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

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

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

As in this example, the upper side of the adjustment top piece is substantially an arc (first adjustment structure), and the position of the arc near the middle protrudes out of the installation space of the second bottom plate 1112221. Wherein, the stepping motor is connected with the adjusting wedge 1112226 so as to push the adjusting wedge to move towards/away from the adjusting top block 1112225. The underside (second adjustment structure) of the adjustment wedges 1112226 may be beveled, curved, or a combination of both. In the orientation shown in the drawings, as in the present embodiment, the underside of the setting wedge is a ramp sloping downwardly from right to left.

In one possible embodiment, the stepper motor can drive the adjusting wedge 1112226 to move to the left by a T-shaped screw 1112229. Preferably, a guide rail 1112228 matched with the motion track of the adjusting wedge can be arranged on the second bottom plate 1112221, so that the stepping motor drives the adjusting wedge to move leftwards along the guide rail through a T-shaped screw rod, and a sliding end 1112227 matched with the guide rail is arranged above the adjusting wedge in the example. The process that the adjusting wedge block moves leftwards can push the adjusting top block to move downwards, and the adjusting top block is fixed on the adjusting plate 1112222, so that the adjusting plate can rotate clockwise around the positioning block 1112223. Similarly, when the stepping motor rotates in the opposite direction, the adjusting wedge 1112226 moves to the right, the adjusting top block 1112225 moves upward, and the adjusting plate 1112222 rotates counterclockwise around the positioning block 1112223.

It can be understood that, on the premise that the accuracy is satisfied, the bottom surface of the adjusting wedge block can be changed into a plane, and the advancing direction of the stepping motor is set to have a certain included angle with the second bottom plate.

In this example, a servo motor is provided on the back side (rear side in the drawing) of the third base plate at a substantially central position, a power output shaft of the servo motor extends out of the front side of the third base plate and is connected to a first gear 11240, a position on the left side of a first rack 11241 located above and a position on the right side of a second rack 11242 located below are engaged with the gear 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 11251 on the left side and a second clamp 11252 on the right side, respectively. In operation, the feeding assembly 111 conveys the silicon rod to the position below the centering assembly 112 and stops moving, and the (first and second) clamping plates respectively move from the outer side to the inner side and stop moving after clamping the silicon rod. To ensure the stability of the movement, the base plate is provided with guide rails and the (first and second) jaws are provided with guide grooves matching the guide rails, so that the rotation of the servo motor drives the gear 11240 to rotate and the (first and second) racks move inwards by means of the engagement with the gear 11240 to move the (first and second) jaws on the guide rails.

The (first and second) clamping plates of the centering assembly 112 adjust the position of the silicon rod in the Y-axis direction, so that the (movable and fixed) chuck of the feeding slide unit 12 reaches a proper position in advance before clamping the silicon rod, and the length of the silicon rod can be measured. The first probe 11261 and the second probe 11262 of the two first probe sets determine the adjustment amount of the position and angle of the silicon rod by inspecting the rear side surface and the upper side surface of the silicon rod, respectively.

The construction of the first/second splint and the arrangement of the first probe set on the respective splint will be described below by taking the second splint 11252 corresponding to the right side as an example. In one possible embodiment, the second jaw 11252 mainly comprises a jaw body 112521, a first mounting plate 112522 and a second mounting plate 112523, wherein the jaw body is used for holding the silicon rod 2, the first mounting plate is provided with a groove 1125221 which is engaged with the aforementioned guide rail on the third bottom plate, and the first probe 11261 is provided on the first mounting plate, the second mounting plate 112523 is substantially parallel to the first mounting plate and is provided at a position lower than and rearward of the first mounting plate, and the second probe 11262 is provided on the second mounting plate.

The second probe 11262 is fixed to the second mounting plate 112523 without the need for an air cylinder. Specifically, the second probe 11262 may be compressed by moving the silicon rod 2 toward the second probe 11262 by the loading device 11, so as to obtain the magnitude of the compression amount. Namely: the detection of the rear side surface of the silicon rod by the second probe 11262 can be achieved along with the movement of the silicon rod in the X-axis direction.

Based on this, the operating principle of the centering assembly 112 is: after the silicon rod 2 is clamped by the pair of clamping plates of the centering assembly 112 and then released, the feeding platform 1131 continues to advance for a certain distance along the X-axis direction, the two second probes 11262 are compressed, so that the external 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. Then, the second 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 for a certain distance, so that the external 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.

The slide table driving system mainly includes a slide table driving motor 1202, a second ball screw 1203, a screw base 1204, and a second rail slider 1205. The screw base 1204 and the second rail slide 1205 are both installed on the vertical frame 102 of the grinding machine 1, and the sliding table driving motor 1202 drives the ball screw to move under the guidance of the second rail slide 1205 and generate displacement along the X-axis direction, so that the sliding table assembly moves along the Y-axis direction. The table casing 1201 is mounted on the second rail slider 1205, and the stationary chuck 121 is fixed to the table casing 1201 to move along the Y-axis in synchronization with the table assembly.

In addition, the fixed chuck 121 and the movable chuck 122 are respectively provided with a fixed chuck rotating motor 1211 and a movable chuck rotating motor 1221 so as to rotate the silicon rod after the silicon rod is clamped by the (fixed, movable) chucks, for example, from one set of surfaces to be ground to another 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 oppositely disposed rough grinding wheels 131 for rough grinding of the silicon rod 2, a pair of oppositely disposed finish grinding wheels 132 for finish grinding of the silicon rod 2, and a detection assembly 133. The finish grinding wheel 132 is located on the downstream side of the rough grinding wheel 133 in the silicon rod feeding direction so as to finish grinding after rough grinding of a certain grinding surface, and the detection unit 133 is disposed on the rough grinding wheel 131 and mainly used for detecting the position of the silicon rod 2 before the grinding operation is started.

In one possible embodiment, the rough grinding motor 1311 drives the fourth ball screw 1312 to drive the carriage 1314 carrying the rough grinding wheel 131 to move in the X-axis direction by the guide of the fourth rail block 1313. The detection unit 133 is mounted on a carriage 1314 for carrying the rough grinding wheel 131. For example, the finish grinding wheel 132 may be moved in a manner similar to that of the rough grinding wheel 131, and will not be described in detail.

In one possible embodiment, the inspection assembly 133 basically includes a base 1331, a base plate 1332, a slide plate 1333, a second probe set, a third air cylinder 1335 and a fifth rail slide 1336.

It can be seen that, in the feeding device of the present invention, in the first aspect, the position of the silicon rod along the Z axis is adjusted by the cooperation of the transmission plate, the connecting shaft and the lifting wheel in the lifting assembly. On the basis, by configuring an eccentric shaft for one of the lifting wheels, the silicon rod can be simultaneously adjusted in angle along the X axis by the lifting assembly. In this way, an adjustment of the feeding precision corresponding to two dimensions is achieved by the lifting assembly. In the second aspect, the adjustment plate fixed on the fixed end clamping plate rotates around the positioning block by increasing the matching of the adjustment wedge block and the adjustment top block in the adjustment assembly for the clamping fixed end assembly of the clamping assembly, so that the angle adjustment of the silicon rod along the Z axis is realized.

In this way, an adjustment of the feeding precision corresponding to the fourth dimension is achieved by the lifting assembly. In summary, according to the scheme of the invention, the silicon rod can be adjusted in four dimensions through the feeding device, and the position adjustment along the Y axis through the centering component and the angle adjustment along the Y axis through the (fixed and movable) chuck are combined (namely, the adjustment can be realized through the centering component under the condition that the deviation is the position along the Y axis, and the rotation of the (fixed and movable) chuck under the condition that the deviation is the angle along the Y axis), so that the feeding accuracy of the grinding machine is ensured, and the feeding accuracy of the grinding machine is ensured.

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

Based on the above structure, an embodiment of the material loading control method of the grinding machine of the present invention will be described below mainly with reference to fig. 19.

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

and S1901, after the silicon rod is initially adjusted by the feeding device, feeding the silicon rod to the grinding area by the sliding table device.

Specifically, after the feeding device 11 finishes adjusting the posture of the silicon rod 2, and the feeding slide unit 12 reaches a predetermined position according to the length of the silicon rod measured by the centering assembly 112, the movable chuck 122 moves along the Y-axis relative to the slide unit, so that the silicon rod is clamped by the fit between the fixed chuck 121 and the movable chuck 122. Thereafter, the feed slide table device 12 is moved along the Y axis, transporting the silicon rod 2 to the grinding area.

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 for 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 so, the process proceeds to S1907.

Before grinding, the silicon rod 2 is inspected by the inspection unit 133. In one possible embodiment, the detection module 133 detects the silicon rod 2 by: when the silicon rod 2 stops moving after reaching 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 with respect to the grinding wheel. Then, the rough grinding wheel 131 and the detection assembly 133 continue to move in the X-axis direction by the drive of the rough grinding motor 1311 until the third probe contacts the silicon rod and detection is completed (dotting and not grinding). Along with the movement of the silicon rod along the Y-axis direction, the third probe can detect the knife inlet position, the middle position along the length of the silicon rod and the knife outlet position of the silicon rod in sequence, then the chuck drives the silicon rod to rotate 90 degrees, and the detection process is repeated.

The determination result of determining that the state of the silicon rod does not satisfy the condition for grinding by the grinding component according to the detection result of the detection component 133 specifically includes: 1) If the maximum grinding size of the silicon rod is smaller than the standard size after grinding, the size of the rod is judged to be unqualified, the rod cannot be ground, and the silicon rod can be returned to the blanking platform (returned). 2) On the premise that the silicon rod is qualified, the position deviation and the angle deviation between the axis of the (fixed or movable) chuck and the axis of the silicon rod can be measured through the measurement of the second probe group on the three positions of the silicon, and if the deviation is greater than a specified value, the state of the silicon rod is considered to be not satisfied with the condition that the grinding component grinds the silicon rod. The cases where the condition is not satisfied mainly include two types: 21 Angle of the silicon rod along the Y-axis has a deviation, which can be adjusted, for example, by rotating the (stationary, movable) chuck; 22 Has a deviation in position/angle of the silicon rod along the (X, Z) axis, which is the case discussed in the present invention, and this case may proceed to S1905.

And S1905, the silicon rod is connected and placed on the feeding platform of the feeding device again (without manual intervention), and the state of the silicon rod is adjusted through the feeding device.

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

After the adjustment is completed, the process returns to S1903 to perform the re-detection, and may proceed to S1907 until the detection is completed and the condition for the grinding assembly to grind the workpiece is satisfied.

And S1907, grinding the silicon rod by the grinding component.

Specifically, the grinding assembly mainly includes a rough grinding wheel and a finish 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 to perform rough grinding. After the rough grinding is finished, the detection assembly repeats the previous detection process to calculate the grinding amount of the finish grinding wheel 132, and the finish grinding wheel advances a certain distance to the X axis similarly according to the grinding amount to carry out finish grinding.

And S1909, finishing grinding and blanking.

After grinding is completed, the feeding sliding table device returns to the blanking area of the feeding device, and at the moment, the (fixed and movable) chuck loosens the silicon rod, so that the silicon rod falls to the blanking table corresponding to the blanking area, and blanking is completed.

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

It should be noted that, although the foregoing embodiments describe each step in a specific sequence, those skilled in the art may understand that, in order to achieve the effect of the present invention, different steps do not have to be executed in such a sequence, and may be executed simultaneously or in other sequences, and some steps may be added, replaced or omitted. Such as may be: the specific switching mode between the rough grinding and the fine grinding can be adjusted according to actual situations; on the premise that the silicon rod does not meet grinding conditions, the silicon rod is directly placed on the feeding device again, only one part (four dimensions (main) and position adjustment along the Y axis corresponding to the centering component) of the silicon rod is adjusted, and the rest part is realized by rotation between (fixed and movable) chucks in the feeding sliding table device; and the like.

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 appreciate that the present invention should not be limited thereto. In fact, the user can flexibly adjust the relevant steps and the parameters and other elements in the steps according to the situations such as practical application scenarios, for example, when the clamping assembly, the lifting assembly and the centering assembly realize the four-dimensional adjustment, the four adjustments can be performed simultaneously or sequentially, and the like.

So far, the technical solutions of the present invention have 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 the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
