Description

Loading table assembly and grinding machine comprising same

Technical Field

The utility model relates to the technical field of feeding adjustment in equipment such as a grinding machine and particularly provides a feeding table assembly and the grinding machine comprising the feeding table assembly.

Background

A grinding machine is a device for grinding a hard and brittle material. Such as grinding machines, typically include a loading table assembly, a feed assembly, and a grinding assembly. For example, the piece made of hard and brittle material is used as a silicon rod, for example, the silicon rod after being opened is firstly fixed to the feeding table assembly, after a certain initial adjustment is carried out on the position and the posture of the silicon rod, the silicon rod is sent 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. At present, the feeding precision of the silicon rod is usually adjusted based on the basic posture of horizontal feeding, and the adjustment requirement under the non-horizontal feeding condition cannot be met.

Disclosure of Invention

The utility model aims to at least partially solve the technical problems, and particularly, under the condition that a silicon rod waits for a workpiece to be fed in a non-horizontal manner, any link of the position deviation and the angle deviation can be restrained or eliminated, so that the feeding precision of the silicon rod is improved on the basis, the feeding alignment precision of the silicon rod is improved to at least a certain extent, the grinding efficiency is improved, the grinding loss is reduced, the grinding allowance of the silicon rod is reduced, and the processing efficiency of a grinding machine and the surface quality of the silicon rod are improved.

In a first aspect, the present utility model provides a loading table assembly comprising at least one support group comprising two support tables having non-planar support surfaces thereon for: the two non-planar supporting surfaces form a bearing space for allowing the workpiece to be processed to be obliquely fed; wherein a relative movement between two support tables of the same support group can be generated close to and/or away from each other.

By this construction, a construction form of one possible construction of the loading table assembly is given. The bearing space formed by the two support surfaces is adjusted with corresponding approaching and/or separating movements. Because the support surface is of a non-planar structure, the adjustment process is often accompanied by angular adjustment.

It will be appreciated that the person skilled in the art may determine the movement pattern that can be generated by the specific body between the two support tables according to the actual requirements, for example, the two support tables may be moved synchronously or in a relatively independent manner, and the generated movement pattern may be only close, only far or both. The position of one of the two support tables is, for example, relatively fixed or can only be switched between a set few positions, the other being freely movable.

It is understood that the number of the supporting groups, the structural form of the supporting table, etc. can be determined by those skilled in the art according to actual requirements. As the two support tables/support surfaces corresponding to the same support group may be the same or different, the support tables/support surfaces corresponding to different support groups may be different or the same.

It will be appreciated that the specific form of the non-planar support surface may be determined by one skilled in the art according to actual requirements, and may be, for example, one/more curved surfaces, one/more inclined surfaces, a combination of one/more curved surfaces and inclined surfaces, etc. Taking a silicon rod as an example of a workpiece to be processed, different local supporting surfaces can be the same or different when observed along the length direction of the silicon rod. Illustratively, the structure in the middle region is different from the structure in the regions near the ends.

It should be noted that, here, the inclined feeding should be understood as: compared with the traditional feeding mode of 'radial horizontal arrangement, axial arrangement along the direction approximately same as the feeding direction and movement direction approximately same as the feeding direction', certain deviation, such as observable deviation, can be deliberately generated in the starting stage. In particular in which direction the deviation occurs to what extent, the person skilled in the art can flexibly set according to the actual production requirements.

For the loading table assembly described above, in one possible embodiment, two of the support tables of the same support group are movable toward/away from each other; and/or the two support tables of the support group can move in a mode of same movement trend.

Through the structure, the position and the angle of the bearing space are expected to be better adjusted through the movement of the supporting table, so that the adjusted bearing space can be adapted to or meet the requirement of feeding precision.

As used herein, the same motion trend is understood to mean the same or substantially the same direction of motion, both being, illustratively, a trend of movement substantially to the right, but may be the same, symmetrical, or less different than the strict right reference, etc.

For the loading table assembly described above, in one possible embodiment, the loading table assembly includes a first guiding mechanism along which two support tables of the same support group are movable.

With this configuration, the first guide mechanism can limit the movement direction, the range, and the like of the two support bases of the same support group.

It is understood that, on the premise of having a guiding function, a person skilled in the art can determine a specific form of the first guiding mechanism and a corresponding guiding direction according to actual requirements. For example, the first guide means may be a baffle, a guide rail arranged in a horizontal plane, a guide rail arranged in a vertical direction, etc., and the guiding direction may be parallel to the feeding direction or have an angle.

For the loading table assembly, in one possible implementation manner, the supporting table is provided with a first driving mechanism, and the first driving mechanism can drive the supporting table to move under the guiding constraint of the first guiding mechanism.

By this construction, a possible driving means is provided by which the support table is moved, for example the first driving means may be a motor, a power cylinder or a linear module formed by a plurality of components, etc.

The first driving mechanism is a screw motor (a linear module which integrates the motor and a screw nut mechanism), the first guiding mechanism is a guide rail sliding block mechanism which is arranged along a horizontal plane, a nut of the screw motor is fixedly connected with the side part of a supporting table, and the bottom of the supporting table is fixedly connected with a sliding block of the guide rail sliding block mechanism.

For the loading table assembly described above, in one possible embodiment, each of the support tables is configured with a first drive mechanism to: each of the support tables is movable independently of the other.

By such a construction, a possible way of constructing the support table group from the support tables is given.

For the loading table assembly, in one possible embodiment, the supporting surface is an inclined surface.

By means of this construction, a possible design of the support surface is provided.

It will be appreciated that the skilled person will be able to determine the details of the inclined plane, such as the shape, size, inclination and degree of inclination of the inclined plane, etc. according to the actual requirements, e.g. the details between the support surfaces of different support tables may be the same or different. Illustratively, the support surfaces of the first support table are inclined upwardly 60 ° from the middle to the outside and the support surfaces of the second support table are inclined upwardly 30 ° from the middle to the outside.

For the loading table assembly described above, in one possible embodiment, the support surfaces of two support tables of the same support group are symmetrically arranged at least in terms of inclination.

By this construction, a possible form of the two support tables forming the support group is given. Illustratively, the support surfaces of two support tables of the same support group are different in shape/area, but are each inclined at 45 °, etc.

For the loading table assembly, in one possible embodiment, the support group includes a plurality of support groups, the loading table assembly includes a second guiding mechanism, and the plurality of support groups can generate relative movement along the second guiding mechanism.

With this configuration, the relative positions of the support groups can be adjusted, so that the support space formed by the plurality of support groups can be adapted to workpieces to be processed having different specifications (such as lengths).

For the loading table assembly, in one possible implementation manner, at least one supporting group is provided with a second driving mechanism, and the second driving mechanism can drive the supporting group to approach/depart from other supporting groups under the guiding constraint of the second guiding mechanism.

By this construction, a possible way of driving the support group to generate the movement is given.

As similar to the first guide mechanism/first drive mechanism described above, the second drive mechanism is a screw motor (a linear module in which a motor and a screw nut mechanism are integrally provided). And on the premise of having a guiding function, a person skilled in the art can determine the specific form, the guiding direction and the like of the second guiding mechanism according to actual requirements, and the second guiding mechanism can also be a baffle plate, a guide rail arranged in a horizontal plane, a guide rail arranged in a vertical direction and the like.

The second guiding mechanism is a guide rail sliding block mechanism which is arranged along a horizontal plane and has a guiding direction perpendicular to the first guiding mechanism (such as a feeding direction), a nut of the screw motor is fixedly connected with the side part of the supporting group, and the bottom of the supporting group is fixedly connected with a sliding block of the guide rail sliding block mechanism.

It can be seen that in a preferred embodiment of the present utility model, the angular adjustment of the workpiece to be machined can be achieved by the loading table assembly by the cooperation of the support surface and the first driving mechanisms of the plurality of support groups. After the detection assembly detects disqualification, compared with the mode of directly blanking the to-be-machined part (withdrawing a rod) and manually participating, the utility model directly places the to-be-machined part in the feeding table assembly of the feeding device for readjustment, thereby improving the adjustment efficiency. Compared with the mode of adjusting through the fixed chuck and the movable chuck in the feeding direction, the feeding precision adjustment of four dimensions can be realized through different parts due to the fact that more parts are involved in the structure of the feeding table assembly. In addition, the feeding device is separated from the movable clamping head and the fixed clamping head in structure, so that the adjustment of corresponding dimensions is easier to realize by adding parts and the like.

In a second aspect, the utility model provides a grinding machine comprising a loading table assembly as defined in any one of the preceding claims.

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

In one possible embodiment, the grinding machine comprises a loading device comprising a loading platform, a unloading platform and a loading and unloading feeding support assembly, wherein the loading platform assembly is arranged on the loading platform.

In one possible embodiment, the grinding machine is a grinding machine for machining silicon rods.

The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, it will be appreciated by those skilled in the art that the present utility model may be practiced without some of these specific details. In some instances, the principles of grinding machines, etc., which are well known to those skilled in the art, have not been described in detail in order to highlight the gist of the present utility model.

The method 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.

The present utility model is described below with reference to some or all of fig. 1 to 11.

Referring mainly to fig. 1, in one possible embodiment, the grinding machine 1 mainly includes a base, and a feeding device 11, a feeding sliding table device 12 and a grinding device 13 disposed on the base, where the base mainly provides a mounting surface with a higher level for structures such as the feeding device 11, the feeding sliding table device 12 and the grinding device 13. Wherein, the feeding device 11 is mainly used for adjusting the silicon rod to a proper position and angle, and the feeding sliding table device 12 comprises a fixed chuck 121 and a movable chuck 122, and the movable chuck can clamp the silicon rod 2 with different axial lengths by moving along the axial direction (the axial direction under ideal conditions) of the silicon rod relative to the fixed chuck. By synchronously rotating the fixed chuck and the movable chuck, the state that the silicon rod reaches the grinding position from one surface to be ground is switched to the state that the other surface to be ground reaches the grinding position.

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 movable chuck and the fixed 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. And then, the fixed chuck and the movable chuck synchronously rotate, so that the silicon rod which is obliquely fed rotates to be in a horizontal state.

Referring primarily to fig. 2, in one possible embodiment, the loading device 11 basically includes a loading table assembly 111, a centering assembly 112 and an upper and lower feed support assembly 113. The feeding table assembly 111 and the feeding and discharging feeding support assembly 113 are mainly used for adjusting the position and the posture of the silicon rod 2, and the centering assembly 112 is used for mainly determining the adjustment amount of the feeding table assembly 111 to the posture of the silicon rod 2.

For ease of description, the present utility model first defines a three-dimensional coordinate system of such a silicon rod. Referring mainly to fig. 3, the silicon rod is placed horizontally as a reference state, the horizontal direction in the reference state is defined as the X-axis (right is the forward direction), the vertical direction in the reference state is defined as the Z-axis (upper is the forward direction), and the feeding direction of the silicon rod is the Y-axis (e.g., the direction toward the inside of the paper is the forward direction). In this embodiment, the silicon rod is rotated 45 ° counterclockwise along its axis as the loading state, and at this time, both the X-axis forward direction and the Z-axis forward direction have been rotated 45 °. Based on this, the definition is increased: the horizontal direction in the feeding state is defined as the X 'axis (right is the forward direction), and the vertical direction in the feeding state is defined as the Z' axis forward direction (upper is the forward direction).

The feeding table assembly is mainly used for positioning the silicon rod by using the supporting table with the inclined surface, and can realize inclined feeding of the silicon rod on a grinding machine. With reference to the definition of the coordinate system, the present utility model aims to convert the above-mentioned angle adjustment amounts for the X-axis and Z-axis directions into angle adjustment amounts for the X '-axis and Z' -axis directions by adjusting the position of the support table having the inclined surface.

Referring primarily to fig. 4, in one possible embodiment, the loading table assembly 111 mainly includes two support groups (e.g., a first support group 1111 and a second support group 1112, respectively) disposed along the feeding and discharging directions, each of which includes two support tables having inclined surfaces, and the two inclined surfaces are disposed opposite to each other and form a substantially V-shaped silicon rod supporting space. It will be appreciated that although the embodiment is illustrated by taking 45 ° as an example, it is obvious that a person skilled in the art can flexibly adjust the rotation angle of the silicon rod, such as 30 °, 60 °, etc., according to actual needs, and at this time, the inclined plane of the support table and the adjustment logic corresponding thereto need to be adjusted accordingly. In summary, the present utility model aims to provide a possible structure that can still adjust the accuracy of a feeding link when a silicon rod is fed in a non-horizontal manner. In addition, the number of the supporting groups can be flexibly adjusted according to actual demands, for example, more groups can be included, or the inclined plane is larger in size along the feeding direction, so that only one group is included.

As in the present example, the support table with inclined surfaces is referred to as V-shaped iron, and the loading table assembly mainly includes V-shaped iron (1) 11111, V-shaped iron (2) 11112, V-shaped iron (3) 11121, V-shaped iron (4) 11122, and V-shaped iron (1) and V-shaped iron (2) near the rear left in fig. 4 constitute one support group, and V-shaped iron (3) and V-shaped iron near the front right in fig. 4 constitute one support group. The 4V-shaped irons (2) have substantially the same structure, and take the V-shaped iron (2) as an example, the V-shaped irons comprise a supporting table 111121 with a columnar structure and a supporting surface 111122 with 45 ° at the top of the columnar structure, and the two supporting surfaces are respectively mounted on a set of X ' guide rail sliding block mechanisms (the sliding blocks move along the X ' direction on the guide rails) 1113, so that the corresponding V-shaped irons can be driven to move along the X ' axis direction by an X ' direction driving component 1114 configured for each V-shaped iron in the X ' guide rail sliding block mechanisms. For example, the X 'driving component may be any power mechanism capable of outputting linear motion, such as a screw motor, a power cylinder (such as a cylinder, an electric cylinder, a hydraulic cylinder, etc.), a screw motor (a screw nut mechanism is configured on the motor and is designed integrally with the motor), and the X' driving component in this example is a screw motor. Both support sets are mounted on a set of Y-track slider mechanisms 1115 such that the spacing between the two support sets along the Y-axis is adjustable.

Based on the structure, the adjustment principle of the feeding table component is as follows:

1) when the V-shaped iron (1) and the V-shaped iron (2) move in the same direction and synchronously along the X ' axis, the V-shaped iron (3) and the V-shaped iron (4) are static or synchronously move in the same direction along the direction opposite to the movement direction of the V-shaped iron (1) and the V-shaped iron (2), the angle adjustment of the axis of the silicon rod in the Z ' axis direction (a certain rotation quantity is generated around the Z ' axis) can be realized. Illustratively, the V-shaped iron (1) and the V-shaped iron (2) move synchronously along the positive direction of the X ' axis, and the V-shaped iron (3) and the V-shaped iron (4) move synchronously along the negative direction of the X ' axis, and at the moment, the silicon rod generates a certain rotation amount along the clockwise direction (seen from top to bottom) around the Z ' axis.

2) When the V-shaped iron (1) and the V-shaped iron (2) synchronously move along the X ' axis in the reverse direction, the V-shaped iron (3) and the V-shaped iron (4) are static or synchronously move in the reverse direction opposite to the movement direction of the V-shaped iron (1) and the V-shaped iron (2), the angle adjustment of the axis of the silicon rod in the X ' axis direction (a certain rotation amount is generated around the X ' axis) can be realized. Illustratively, the V-shaped iron (1) and the V-shaped iron (4) move in the positive direction of the X ' axis, and the V-shaped iron (2) and the V-shaped iron (3) move in the negative direction of the X ' axis, and at this time, the silicon rod rotates clockwise (seen from left to right) around the X ' axis by a certain amount.

3) When the V-shaped iron (1) and the V-shaped iron (2) move in the same direction and synchronously along the X ' axis, and the V-shaped iron (3) and the V-shaped iron (4) move in the same direction and synchronously along the same direction as the movement direction of the V-shaped iron (1) and the V-shaped iron (2), the position adjustment of the axis of the silicon rod in the X ' axis direction (a certain displacement is generated along the X ' axis) can be realized. Illustratively, in the case where the V-shaped iron (1) and the V-shaped iron (2) and the V-shaped iron (3) and the V-shaped iron (4) are both moved rightward in synchronization, the axis of the silicon rod is moved rightward by a certain distance, and in the case where both are moved leftward in synchronization, the axis of the silicon rod is moved leftward by a certain distance.

4) When the V-shaped iron (1) and the V-shaped iron (2) move along the X ' axis reversely and synchronously, and the V-shaped iron (3) and the V-shaped iron (4) move reversely and synchronously along the same direction as the movement direction of the V-shaped iron (1) and the V-shaped iron (2), the position adjustment of the axis of the silicon rod in the Z ' axis direction (a certain displacement is generated along the Z ' axis) can be realized. Illustratively, in the case where the V-shaped iron (1) and the V-shaped iron (2) and the V-shaped iron (3) and the V-shaped iron (4) are close to each other, respectively, the axis of the silicon rod is raised, and in the case where they are far from each other, the axis of the silicon rod is lowered.

In addition, the distance between the two groups of V-shaped irons can be adjusted by enabling the two supporting groups to move along the Y-axis direction, so that silicon rods with different lengths can be better adapted.

And the height of the axis of the silicon rod of different specifications can be made approximately the same according to the position adjustment movement mode in the Z' axis direction. Referring to fig. 5 and 6, if the previous position is adapted to the silicon rod with smaller circumferential specification (e.g. 182), when the circumferential dimension of the silicon rod to be processed is enlarged (e.g. 210), the silicon rods with two specifications can be ensured to have approximately the same height by only reversely synchronously moving the V-shaped iron (1) and the V-shaped iron (2) along the X' axis (the V-shaped iron (1) leftwards and the V-shaped iron (2) rightwards), reversely synchronously moving the V-shaped iron (3) and the V-shaped iron (4) along the same direction as the moving direction of the V-shaped iron (1) and the V-shaped iron (2) (the V-shaped iron (3) leftwards and the V-shaped iron (4) rightwards). If the previous position is matched with the silicon rod with larger circumferential specification, when the circumferential dimension of the silicon rod to be processed is reduced, the motion of the related V-shaped iron is just opposite to the motion, and the description is omitted here.

The feeding process is as follows: and carrying the silicon rod to the upper material table component by adopting a mechanical arm or human intervention mode and the like. The feeding and discharging supporting component drives the feeding table component to move to the lower portion of the centering component along the feeding direction, the clamping plate group of the centering component clamps the silicon rod, two groups of probes on the centering component detect the deviation of the silicon rod on two surfaces of the silicon rod, and specifically, the position deviation and the angle deviation between the axis of the silicon rod and the axis of the clamping plate group are detected. After the detection is completed, the feeding table component adjusts the position/angle of the X 'axis and Z' axis direction of the silicon rod according to the detection result. And detecting again after adjustment, and after determining that the silicon rod is adjusted to a proper position and angle, driving the feeding table assembly to move along the feeding direction by the feeding and discharging feeding support assembly, and clamping the silicon rod by the fixed chuck and the movable chuck of the feeding sliding table device to finish the feeding process.

In one possible embodiment, the feeding and discharging support assembly 113 mainly includes a feeding platform, a discharging platform, and two sets of driving transmission mechanisms disposed therebetween. If the driving transmission mechanism comprises a motor and a screw nut mechanism, the feeding platform and the discharging platform are respectively driven by the two motors to move along the feeding and discharging directions, so that the position adjustment of the silicon rod along the feeding and discharging directions is realized, and the feeding process and the discharging process are completed. An organ shield can be arranged between the feeding platform and the discharging platform to play a certain role in water and dust prevention.

Referring primarily to fig. 7, in one possible embodiment, the centering assembly 112 mainly includes a centering base plate and a clamping plate set (respectively denoted as a first clamping plate 1121 and a second clamping plate 1122) disposed on the centering base plate, for example, a centering motor is disposed on the centering base plate, and the centering motor is configured to detect an adjustment amount required to adjust the silicon rod through a rack-and-pinion mechanism (one gear and two racks engaged with the gear, respectively denoted as a first rack 1123 and a second rack 1124), the first rack and the second rack are fixedly connected to the first clamping plate and the second clamping plate, respectively, and one probe set is disposed on the first clamping plate and the second clamping plate, respectively, and the probe set includes two probes (respectively denoted as a first probe 1125 and a second probe 1126). 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 the appropriate positions in advance before clamping the silicon rod by adjusting the positions of the silicon rod in the feed direction, and the length of the silicon rod can be measured. The pair of first probes and the pair of second probes determine the position and the angle adjustment amount of the silicon rod by detecting the rear side surface and the upper side surface of the silicon rod, respectively.

The external dimension of the silicon rod 2 is calculated according to the compression amount of the head of the first probe after the head of the first probe is protruded to touch the upper side surface of the silicon rod 2. After the inspection, the head portion thereof needs to be moved away from the upper surface of the silicon rod 2 by a driving member such as a cylinder. The second probe can be compressed only by moving the silicon rod 2 to the direction close to the second probe through the feeding device 11, so that the size of the compression amount is obtained, and a driving component is not needed to be arranged.

Based on the above structure, the centering assembly 112 operates on the following principle: the clamping plates of the centering assembly 112 clamp the silicon rod 2 and then loosen, and the feeding platform continues to advance a certain distance along the feeding direction to compress a pair of second probes, so that the overall dimension (width) of the silicon rod 2 along the feeding and discharging directions is obtained, and the width difference between the two ends of the silicon rod 2 is obtained through the pair of second probes. And then the two first probes are driven to extend out through the air cylinder, so that the heads of the two first probes are contacted with the upper surface of the silicon rod and compressed for a certain distance, the outline dimension (height) of the silicon rod along the length direction is obtained, and the height difference of the two ends of the silicon rod is obtained through the pair of first probes. 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.

Referring mainly to fig. 8, in one possible embodiment, the feeding slipway device 12 mainly includes a slipway assembly and a fixed chuck 121 and a movable chuck 122 disposed on the slipway assembly, where the slipway assembly mainly includes a slipway housing and a slipway driving system, the fixed chuck 121 and the movable chuck 122 are disposed on the slipway housing, and the slipway driving system mainly includes a slipway driving motor 1231, a fixed chuck rotating motor 1232 and a movable chuck rotating motor 1233 that drive the fixed chuck 111 and the movable chuck 122 to rotate respectively, and a movable chuck driving motor 1234 that drives the movable chuck to approach/depart from the fixed chuck along the length direction of the silicon rod. The sliding table driving motor 1231 drives the sliding table assembly to move along the length direction of the silicon rod so as to realize the feeding movement of grinding operation, the movable chuck driving motor is mainly used for reliably clamping the silicon rods with different lengths, and the fixed chuck rotating motor and the movable chuck rotating motor are mainly used for rotating the silicon rod after the (fixed and movable) chucks clamp the silicon rod, for example, the silicon rod can be rotated from one group of surfaces to be ground to the other group of surfaces to be ground.

Referring mainly to fig. 9 to 11, in one possible embodiment, the grinding device 13 mainly includes a pair of oppositely disposed rough grinding stones 131 (for rough grinding the silicon rod), a pair of oppositely disposed finish grinding stones 132 (for finish grinding the silicon rod), and a detection assembly 133. Wherein the rough grinding wheel 131 and the finish grinding wheel 132 are moved in a direction approaching/separating from the silicon rod in a radial direction so as to start the grinding operation by approaching the silicon rod and to exit in time at the end of the grinding operation. The detecting assembly 133 mainly comprises a set of detecting probes 1334 (e.g. three) which are extended to detect the position of the silicon rod 2 before the grinding operation is started, and it is confirmed whether the current position of the grinding surface meets the requirement of the grinding operation, if not, the precision of the grinding surface needs to be adjusted by means of rotation of the (movable and fixed) chucks, the feeding table assembly and the like. After the test is completed, the test probe 1334 is retracted.

As in the present example, the fine grinding wheel 132 is located on the downstream side of the rough grinding wheel 133 in the silicon rod feed direction, and a detection unit is mounted on the rough grinding wheel 133. As may be the case where the finishing wheel and the finishing wheel are arranged in a concentrated manner. Such as a rough grinding wheel, is arranged in the middle of the fine grinding wheel in a telescopic manner.

Based on the above structure, the working process of the grinding machine 1 of the present utility model is approximately as follows:

after the loading device 11 completes the pose adjustment of the silicon rod 2, the feeding sliding table device 12 moves relative to the sliding table assembly along the feeding direction after reaching a preset 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 clamp 121 and the movable clamp 122. Thereafter, the feed slide device 12 moves in the feed direction, carries the silicon rod 2 to the grinding area, the feed slide device 12 moves the silicon rod in the feed direction and rotates the silicon rod in accordance with the program setting, and the grinding is completed. After finishing grinding, the feeding sliding table device returns to the blanking area of the feeding device 11, 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.

The inspection assembly 133 inspects the silicon rod 2 before grinding. Specifically, when the silicon rod 2 stops moving after coming to the first inspection position, a set of inspection probes of the inspection assembly 133 are extended, and the inspection probes 1331 are positioned ahead of the grinding wheel. The rough grinding wheel 131 and the inspection assembly 133 then continue to radially approach the silicon rod until the inspection probe contacts the silicon rod and inspection is completed (dotted unground). With the movement of the silicon rod along the feeding direction, the detection 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 90 degrees, so that the detection process is repeated.

Based on the detection result of the detection unit 133, it is determined whether or not the foregoing grinding process including the rough grinding operation and the finish grinding operation is performed on the silicon rod 2. Specifically, if the maximum grinding size of the silicon rod is smaller than the standard size after grinding, judging that the size of the bar is unqualified and cannot be ground, and if so, withdrawing the rod, namely withdrawing the silicon rod to a blanking platform, and then performing manual intervention to different degrees. On the premise that the silicon rod is qualified, the position deviation and the angle deviation between the axis of the fixed and movable chucks and the axis of the silicon rod are determined through detection, if the related position/angle deviation of the X 'axis and the Z' axis is the same, the silicon rod is returned to a feeding table of a feeding device, the pose of the silicon rod is secondarily adjusted on the feeding table through the feeding table assembly, and the detection is carried out again after the adjustment is completed.

After the inspection is completed, grinding can be started. The grinding amount of the rough grinding wheel 131 can be calculated in the detection process, and according to the grinding amount, the rough grinding wheel is first extended to perform rough grinding operation. After the rough grinding is finished, the detection assembly repeats the previous detection process, the grinding quantity of the fine grinding wheel 132 is calculated, and the fine grinding wheel is extended to conduct fine grinding operation according to the grinding quantity. In the utility model, there is a direct correlation between the loading table assembly and the detecting assembly, so that in an alternative situation, two sets of probes corresponding to the centering assembly and the centering assembly can be properly reduced or even directly omitted.

It should be specifically noted that the present utility model aims at providing an adjustment concept for tiltable feeding and providing the most basic direction/position adjustment. If the adjustment structure and logic of the utility model can be further refined according to the requirement, or other known or newly set functional structures such as lifting along the height direction, clamping along the radial direction, angle adjustment and the like are added on the basis of the feeding table assembly of the embodiment, so that the adjustment precision of the feeding table assembly is further ensured. If positional deviations in other feed directions are involved, corresponding adjustments may be made by other structures, such as may include, but are not limited to: position adjustment of the feeding direction is realized through the centering component; the angle adjustment of the feeding direction is realized by the rotation combination of the fixed chuck and the movable chuck; etc.

It can be seen that in the feeding device of the present utility model, by the feeding table assembly in this example, it is expected that the silicon rod is obliquely fed in a case where it is required. And corresponding adjustment logic is configured for the two pairs of V-shaped irons, so that the position/angle adjustment of the X 'axis and the Z' axis is realized. Based on this, be expected to carry out reasonable adjustment to the position and the gesture of silicon rod through the material loading platform subassembly to the material loading precision of grinding machine has been guaranteed. On the basis, the silicon rod can be switched to a posture capable of grinding the silicon rod by synchronous rotation of the fixed chuck and the movable chuck.
