Loading attachment reaches grinding machine including this loading attachment

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 device and the grinding machine comprising the feeding device.

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.

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.

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

The present utility model is described below with reference to some or all of fig. 1 to 14.

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

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

In one possible embodiment, the loading device 11 mainly includes a loading table assembly 111, a centering assembly 112, and an upper and lower feed support assembly 113. The loading table assembly 111 and the loading/unloading feeding support assembly 113 need to adjust the position and the posture (hereinafter referred to as the pose) of the silicon rod 2 in the aforementioned four dimensions, and the centering assembly 112 is used for mainly determining the adjustment amount of the loading table assembly 111 to the pose of the silicon rod 2. Specifically, the loading table assembly 111 generally includes a lift assembly 1111, a clamp assembly 1112, and an adjustment table assembly 1113. In a general case, a loading bracket is installed on a loading platform of the loading and unloading feeding support assembly, and the lifting assembly and the clamping assembly are integrated on the loading bracket. According to the detection result of the centering assembly 112, the lifting assembly 1111 is mainly used for carrying the silicon rod 2 and adjusting the position of the silicon rod along the Z axis, and the clamping assembly 1112 is mainly used for clamping the silicon rod 2 carried on the lifting assembly along the X direction. The adjustment table assembly 1113 is mainly used for performing an angle adjustment along the X-axis (rotation along the X-axis) and an angle adjustment along the Z-axis (rotation along the Z-axis) on a silicon rod (i.e., a silicon rod and an integrated structure in which the silicon rod is mounted/clamped) including the lifting assembly 1111 and the clamping assembly 1112. The feeding and discharging support assembly 113 is mainly used for adjusting the position of the silicon rod along the X axis in the process of moving the feeding table assembly 111 clamping the silicon rod 2 to the centering assembly 112. Based on this, after the loading table assembly 111 completes the adjustment of the silicon rod in four dimensions, the (fixed and movable) chucks are made to clamp the silicon rod with the pose reaching the standard, and the loading process is completed. Wherein the surface of the lifting assembly contacting the silicon rod (reference surface a described below) and the surface of the clamping assembly contacting the silicon rod (reference surface b described below) are references for positioning the silicon rod.

The feeding process is as follows: and the silicon rod is carried to the lifting assembly (the reference surface a) by adopting a mechanical arm or human intervention mode and the like, and the silicon rod is clamped by the clamping assembly (the silicon rod is abutted against the reference surface b), so that the preliminary positioning of the silicon rod is realized. The feeding and discharging supporting component drives the feeding table component to move to the lower portion of the centering component along the X-axis 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 in the Z-axis/X-axis direction are detected. After the detection is completed, the feeding table component adjusts the position of the silicon rod in the Z-axis direction and the angle of the silicon rod in the Z-axis/X-axis direction according to the detection result. As in the present utility model, the Z-axis direction position adjustment of the silicon rod is achieved by the lift assembly, and the Z-axis/X-axis direction angle adjustment of the silicon rod is achieved by the adjustment of the table assembly. 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 X-axis direction by the feeding and discharging supporting assembly so as to adjust the position of the silicon rod in the X-axis direction. After the feeding assembly completes the adjustment of the silicon rod in four degrees of freedom, the fixed chuck and the movable chuck of the feeding sliding table device clamp the silicon rod, and the feeding process is completed.

Referring primarily to fig. 3-4, in one possible embodiment, the lifting assembly 1111 basically includes a lifting base plate 11111, an electric cylinder 11112 (driving member), a driving plate 11113 as a driving member, a lifting wheel set including a first lifting wheel 111141 (e.g., the first lifting wheel includes two wheel units disposed on a first axle 111191) and a second lifting wheel 111142, and a supporting plate 111151, the driving plate 11113 having inclined surfaces 111131 inclined downward from left to right as guiding surfaces at positions corresponding to the first lifting wheel 111141 and the second lifting wheel 111142, respectively.

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

Thus, when the power output end 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 accordance with the above, the two lifting wheels mounted on the pallet can roll from right to left along the inclined plane 111131 plate, namely from low to high, and along with the rolling, the pallet can be driven to generate displacement along the vertical direction. Thus, the silicon rod arranged on the supporting plate realizes the position adjustment along the Z axis. Similarly, the power take off of the electric cylinder 11112 is retracted, the drive plate 11113 is moved to the left, the lift wheel rolls from high to low, and the pallet is lowered. For example, for better guiding the movement of the drive plate 11113, a rail can be provided on the lifting base plate 11111, which rail is adapted to the movement path of the drive plate 11113.

In this example, the body portion of the lift assembly includes a generally open-bottomed enclosure structure with the pallet disposed on top of the enclosure structure and the lift wheels disposed on the sides of the enclosure structure. Illustratively, the two lift wheels are mounted to the body portion in the following manner: first lift wheel 111141 and second lift wheel 111142 are mounted to sides of the housing structure by first axle 111191 and second axle 111192, respectively. Upon extension/retraction of the electric cylinder 11112, the lifting/resetting of the pallet is effected with the rotation of the two lifting wheels and their rolling on the ramp 111131.

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

For example, two sides extending along the length direction of the top of the supporting plate 111151 are respectively provided with an upwardly extending supporting plate 111152, the upper surface of the supporting plate 111152 is a reference surface (such as reference surface a) directly contacting the lower surface of the silicon rod 2, for example, an anti-slip layer or an anti-slip structure made of polyurethane can be added to the upper side of the supporting plate, and the foregoing recess is formed at the position of the supporting plate near the middle, which is specifically implemented as follows: each side is provided with two separate support plates 111152, for example, which can be secured to the top of the pallet by means of fasteners such as screws, forming a recess therebetween. In this example, the support plate has a structure of avoiding the silicon rod at the mounting portion corresponding to the screw, such as a plurality of mounting positions provided on the support plate, the screw is provided at a position corresponding to the mounting position, and in the mounted state, the screw is completely accommodated at the mounting position and thus the top of the screw is not in contact with the bottom of the silicon rod.

It will be appreciated that the manner of forming the recess in the upper surface of the pallet may be flexibly adapted by those skilled in the art according to the actual requirements, e.g. two separate support plates may be integrally provided and then the middle portion may be provided as a recess, the support plates may be integrally provided with the pallet, etc.

In one possible embodiment, the lifting floor 11111 is provided with a connecting shaft 1117 which cooperates with the first plate 111151, and a return spring 1118 is provided between the lifting floor and the first plate. By the arrangement of the connection shaft 1117, the movement of the pallet in the X-axis and Y-axis directions is restricted, and thus the pallet can move only in the Z-axis direction under the guidance of the connection shaft. When the cylinder 11112 is extended and the pallet is raised, the return spring 1118 is in a compressed/stretched (as in this example, compressed) state.

In operation, the loading table assembly 111 conveys the silicon rod to the lower side of the centering assembly 112, and then stops moving, and the (first and second) clamping plates move from the outer side to the inner side respectively, and clamp the silicon rod and then stop moving. In order to ensure the stability of movement, the bottom plate is provided with a guide rail, the (first and second) clamping plates are provided with guide grooves matched with the guide rail, so that the servo motor rotates to drive the gear 11240 to rotate, and the (first and second) racks drive the (first and second) clamping plates to move inwards in a mode of moving on the guide rail by meshing with the gear 11240.

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

The configuration of the first/second clamping plates and the arrangement of the first probe set on the corresponding clamping plates will be described below by taking the second clamping plate 11252 corresponding to the right side as an example.

Namely: detection of the rear surface of the silicon rod by the second probe 11262 can be achieved with movement of the silicon rod in the X-axis direction.

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

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

Referring mainly to fig. 1, 12 to 14, in one possible embodiment, the grinding device 13 mainly includes a pair of rough grinding stones 131 disposed opposite to each other for rough grinding the silicon rod 2, a pair of fine grinding stones 132 disposed opposite to each other for fine grinding the silicon rod 2, and a detection unit 133. Wherein, the fine grinding wheel 132 is located at the downstream side of the rough grinding wheel 133 along the feeding direction of the silicon rod so as to perform fine grinding after rough grinding of a certain grinding surface, and the detecting component 133 is configured on the rough grinding wheel 131 and is mainly used for detecting the position of the silicon rod 2 before the grinding operation starts.

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

In one possible embodiment, the detection assembly 133 basically includes a base 1331, a base 1332, a slide plate 1333, a second probe set, a third cylinder 1335 and a fifth rail slider 1336. Wherein the base plate 1332 is fixed on the base plate 1331, and the sliding plate 1333 is disposed on the base plate 1332 through a fifth guide rail slider 1336 group, for example, the second probe group includes three third probes 1334 arranged in a vertical direction and mounted on the sliding plate 1333. During detection, the third cylinder 1335 extends to push the sliding plate 1333 to extend along the X-axis direction, and after detection is finished, the third cylinder 1335 retracts to pull the sliding plate 1333 to retract.

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 along the Y axis relative to the sliding table assembly 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 feeding slide means 12 moves along the Y axis, carries the silicon rod 2 to the grinding area, the feeding slide means 12 moves the silicon rod along the Y axis 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 detection position, the third cylinder 1335 of the detection assembly 133 is extended to push the third probe 1334 to move along the X-axis direction, and the position of the third probe 1334 is advanced to the grinding wheel. Then, the rough grinding wheel 131 and the inspection unit 133 continue to move in the X-axis direction by the driving of the rough grinding motor 1311 until the third probe contacts the silicon rod and the inspection is completed (dotting is not ground). Along with the movement of the silicon rod along the Y-axis direction, the third probe can detect the knife-in position of the silicon rod, the middle position along the length of the rod and the knife-out position of the silicon rod in sequence, and then the chuck drives the silicon rod to rotate by 90 degrees, so that the detection process is repeated.

From the detection result of the detection unit 133, it is determined whether or not the foregoing grinding process 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 can be measured through the measurement of the second probe set on three positions of the silicon, if the deviation related to the four dimensions (namely, the deviation within the adjusting capacity of the feeding device) is larger than a specified value, the silicon rod is returned to the feeding table of the feeding device, the pose of the silicon rod is secondarily adjusted on the feeding table, and the detection is carried out again after the adjustment is completed. As in the case of a deviation to a position along the Y-axis, can be adjusted by the centering assembly. This can be achieved by feeding the (stationary, moving) jaws of the ramp device, as in the case of a deviation of the angle along the Y-axis. 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 the rough grinding wheel advances a certain distance to 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, the grinding amount of the fine grinding wheel 132 is calculated, and the fine grinding wheel is advanced to the X axis by a certain distance according to the grinding amount, so that fine grinding is performed. In the present utility model, there may be a direct association between the loading table assembly and the detection assembly, so that the aforementioned first probe set corresponding to the centering assembly may be appropriately reduced or omitted in alternative cases.

It can be seen that in the feeding device, the position adjustment of the silicon rod along the Z axis is realized through the cooperation of the transmission plate, the connecting shaft and the lifting wheel in the lifting assembly in the example. The clamping of the silicon rod carried on the supporting plate along the X-axis direction is realized through the clamping assembly in the example. By configuring the adjusting table assembly for the lifting assembly and the clamping assembly on the basis, the angle adjustment of the silicon rod along the X axis and the angle adjustment along the Z axis can be realized. And the feeding and discharging support assembly is added to adjust the position of the silicon rod along the X axis in the process of moving the feeding table assembly holding the silicon rod. Based on the scheme of the utility model, the four-dimensional adjustment of the silicon rod can be realized through the feeding device, and the six degrees of freedom of the silicon rod can be effectively adjusted by combining the position adjustment along the Y axis mainly realized through the centering component and the angle adjustment along the Y axis realized through the matching modes of the (fixed and movable) chucks and the like, so that the feeding precision of the grinding machine is ensured.
