They are made by cutting indium phosphide crystal rods. During the manufacturing process, the end faces of the crystal rods need to be chamfered.

[0003] However, existing chamfering devices can only chamfer one end at a time, and the other end must be chamfered after one end is finished, resulting in low chamfering efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a crystal rod chamfering device that simultaneously chamfers both ends of the crystal rod, thereby improving chamfering efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A crystal ingot chamfering device includes a frame and a crossbeam, a feeding mechanism, a discharging mechanism, a chamfering mechanism, and a steering and positioning mechanism disposed on the frame. The feeding mechanism, the discharging mechanism, and the chamfering mechanism are all disposed below the crossbeam, with the feeding mechanism and the discharging mechanism respectively disposed at both ends of the crossbeam. There are two chamfering mechanisms, which are disposed opposite to the feeding mechanism and between the two chamfering mechanisms. The steering and positioning mechanism is disposed on one side of the chamfering mechanism and between the two chamfering mechanisms. A conveying mechanism is slidably disposed on the crossbeam.

[0007] Preferably, a first motor is provided at one end of the crossbeam, a first lead screw is connected to the first motor, and the first lead screw extends along the length direction of the crossbeam.

[0008] Preferably, the conveying mechanism includes a lifting cylinder connected to the first slider, and a first clamping cylinder is provided on the telescopic rod of the lifting cylinder, and the first clamping cylinder is provided with two first grippers that can move towards or away from each other.

[0009] Preferably, the steering positioning mechanism includes a support base vertically fixed on the frame, a second motor at the upper end of the support base, a vertically arranged second lead screw connected to the second motor, a fixing plate threaded onto the second lead screw, a rotary motor on the fixing plate, a second clamping cylinder on the rotating shaft of the rotary motor, and two second grippers that can move toward or away from each other on the second clamping cylinder.

[0010] Preferably, the rotating shaft of the rotary motor is provided with a cylinder fixing plate, and the second clamping cylinder is fixed on the cylinder fixing plate.

[0011] Preferably, both the feeding mechanism and the unloading mechanism include a support plate horizontally fixed on the frame. One end of the support plate is provided with a third motor. A third lead screw is connected to the shaft of the third motor. A second slider is provided on the third lead screw. A fixture for placing crystal rods is provided on the second slider.

[0012] Preferably, the fixture includes a fixture body, which has a plurality of receiving grooves for placing crystal rods, and the cross-sectional shape of the receiving grooves is the same as the cross-sectional shape of the crystal rods.

[0015] Preferably, both ends of the crossbeam are provided with support rods, and the lower end of the support rods is connected to the frame.

[0016] This utility model discloses a crystal ingot chamfering device. Compared with the prior art, its advantages are as follows: A loading mechanism, a unloading mechanism, and a chamfering mechanism are arranged below a crossbeam, with the loading and unloading mechanisms located at opposite ends of the crossbeam. Two chamfering mechanisms are arranged opposite each other between the loading and unloading mechanisms. A steering and positioning mechanism is located on one side of the chamfering mechanisms, between the two chamfering mechanisms. A conveying mechanism is slidably arranged on the crossbeam. When chamfering of the crystal ingot is required, the crystal ingot is first placed on the loading mechanism. The conveying mechanism moves the crystal ingot from the loading mechanism to the steering and positioning mechanism, and then the steering and positioning mechanism clamps it. The crystal ingot is detached from the transport mechanism, and the steering and positioning mechanism drives the crystal ingot to rotate, making the crystal ingot horizontal. Then, two chamfering mechanisms move towards the crystal ingot, respectively abutting against both ends of the crystal ingot and completing the chamfering operation on both ends of the crystal ingot. After chamfering, the two chamfering mechanisms move in opposite directions, detach from the crystal ingot, and the steering and positioning mechanism drives the crystal ingot to rotate to a vertical position. Then, the transport mechanism moves to the crystal ingot to clamp the crystal ingot. After clamping, the steering and positioning mechanism detaches from the crystal ingot, and the transport mechanism moves the crystal ingot to the unloading mechanism for storage. The chamfering process is completed. During the chamfering process, both ends of the crystal ingot are chamfered simultaneously, which improves the chamfering efficiency of the crystal ingot.

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] like Figure 1As shown in the figure, a preferred embodiment of the present invention provides a crystal rod chamfering device, including a frame (not shown) and a crossbeam 1, a feeding mechanism 2, a discharging mechanism 3, a chamfering mechanism 4, and a steering and positioning mechanism 5 mounted on the frame. The feeding mechanism 2, the discharging mechanism 3, and the chamfering mechanism 4 are all located below the crossbeam 1, with the feeding mechanism 2 and the discharging mechanism 3 respectively located at both ends of the crossbeam 1. There are two chamfering mechanisms 4, positioned opposite each other between the feeding mechanism 2 and the discharging mechanism 3. The steering and positioning mechanism 5 is located on one side of the chamfering mechanism 4, between the two chamfering mechanisms 4. A conveying mechanism 6 is slidably mounted on the crossbeam 1. That is, only the conveying mechanism 6 is connected to the crossbeam 1; the other mechanisms are not connected to the crossbeam 1. Simultaneously, support rods 9 are provided at both ends of the crossbeam 1, with the lower ends of the support rods 9 connected to the frame; that is, the crossbeam 1 is connected to the frame through the support rods 9.

[0032] The crystal ingot chamfering device based on the above features comprises a loading mechanism 2, a unloading mechanism 3, and a chamfering mechanism 4 arranged below a crossbeam 1. The loading mechanism 2 and the unloading mechanism 3 are respectively located at both ends of the crossbeam 1, and there are two chamfering mechanisms 4 arranged opposite to each other between the loading mechanism 2 and the unloading mechanism 3. A steering and positioning mechanism 5 is located on one side of the chamfering mechanism 4, between the two chamfering mechanisms 4. A conveying mechanism 6 is slidably mounted on the crossbeam 1. When chamfering of the crystal ingot 100 is required, the crystal ingot 100 is first placed on the loading mechanism 2. The conveying mechanism 6 moves the crystal ingot 100 from the loading mechanism 2 to the steering and positioning mechanism 5. Then, the steering and positioning mechanism 5 clamps the crystal ingot 100, and the conveying mechanism 6 disengages from the crystal ingot 100 and turns... The positioning mechanism 5 drives the crystal rod 100 to rotate, making the crystal rod 100 horizontal. Then, the two chamfering mechanisms 4 move toward the crystal rod 100 and abut against both ends of the crystal rod 100 respectively, completing the chamfering operation on both ends of the crystal rod 100. After the chamfering is completed, the two chamfering mechanisms 4 move in opposite directions, disengaging from the crystal rod 100. The turning positioning mechanism 5 drives the crystal rod 100 to rotate to a vertical position. Then, the conveying mechanism 6 moves to the crystal rod 100 to clamp the crystal rod 100. After clamping is completed, the turning positioning mechanism 5 disengages from the crystal rod 100, and the conveying mechanism 6 moves the crystal rod 100 to the unloading mechanism 3 for storage. The chamfering process is completed. During the chamfering process, both ends of the crystal rod 100 are chamfered simultaneously, improving the chamfering efficiency of the crystal rod 100.

[0033] like Figure 2As shown, in this embodiment, a first motor 7 is provided at one end of the crossbeam 1. A first lead screw 8 is connected to the first motor 7 and extends along the length direction of the crossbeam 1. A first slider 61 is provided on the first lead screw 8, and the conveying mechanism 6 is connected to the first slider 61. When the conveying mechanism 6 needs to move, the first motor 7 starts, driving the first lead screw 8 to rotate. Under the action of the first lead screw 8, the first slider 61 moves along the length direction of the first lead screw 8, realizing the movement of the conveying mechanism 6 driven by the first slider 61. The conveying mechanism 6 includes a lifting cylinder 62 connected to the first slider 61. A first clamping cylinder 63 is provided on the telescopic rod of the lifting cylinder 62. The first clamping cylinder 63 is provided with two first grippers 64 that can move towards or away from each other. The first clamping cylinder 63 drives the first grippers 64 to clamp the crystal ingot 100. That is, the first clamping cylinder 63 can be raised and lowered under the action of the lifting cylinder 62. Thus, when clamping the crystal ingot 100 on the loading mechanism 2 or transferring the crystal ingot 100 to the unloading mechanism 3, it first moves under the action of the first slider 61. Once it reaches the accurate position, the lifting cylinder 62 drives the crystal ingot 100 to rise and fall, thus clamping or storing the crystal ingot 100. When the conveying mechanism 6 moves to the steering and positioning mechanism 5, after the steering and positioning mechanism 5 clamps the crystal ingot 100 and the first gripper 64 disengages from the crystal ingot, the lifting cylinder 62 needs to drive the first gripper 64 upwards to prevent the first gripper 64 from affecting the steering and positioning mechanism 5's rotation of the crystal ingot 100.

[0034] In addition, the crystal rods 100 are all placed vertically on the feeding mechanism 2 and the unloading mechanism 3. Therefore, the first gripper 64 is set vertically, and the inner surface of the first gripper 64 is provided with a slot that matches the outer surface of the crystal rod 100. When clamping the crystal rod 100, the inner wall of the slot is in contact with the outer surface of the crystal rod 100, which not only ensures the clamping of the crystal rod 100, but also avoids damage to the outer surface of the crystal rod 100.

[0035] like Figure 3As shown, the steering and positioning mechanism 5 includes a support base 51 vertically fixed on the frame. A second motor 52 is mounted on the upper end of the support base 51. A vertically arranged second lead screw 53 is connected to the second motor 52. A fixing plate 54 is threaded onto the second lead screw 53. A rotary motor 55 is mounted on the fixing plate 54. A second clamping cylinder 56 is mounted on the shaft of the rotary motor 55. The second clamping cylinder 56 has two second grippers 57 that can move towards or away from each other. The second clamping cylinder 56 drives the second grippers 57 to clamp the crystal ingot 100. That is, both the rotary motor 55 and the second clamping cylinder 56 can be raised and lowered under the action of the fixing plate 54. Combined with the lifting function of the conveying mechanism 6, the steering and positioning mechanism 5 and the conveying mechanism 6 can be perfectly coordinated to achieve the transfer and clamping of the crystal ingot 100.

[0036] Both the first clamping cylinder 63 and the second clamping cylinder 56 can be two cylinders, each cylinder connected to a gripper, or they can be a single bidirectional telescopic cylinder, with the telescopic rods at both ends of the bidirectional telescopic cylinder connected to a gripper respectively. In this application, a single bidirectional telescopic cylinder is preferred.

[0037] Meanwhile, to ensure the installation stability of the second clamping cylinder 56, a cylinder fixing plate 58 is provided on the rotating shaft of the rotary motor 55, and the second clamping cylinder 56 is fixed on the cylinder fixing plate 58. The inner wall of the second gripper 57 is also provided with a slot that matches the outer surface of the crystal ingot 100. When clamping the crystal ingot 100, the inner wall of the slot is in contact with the outer surface of the crystal ingot 100, which not only ensures the clamping of the crystal ingot 100, but also avoids damage to the outer surface of the crystal ingot 100.

[0038] Please see the appendix Figure 4 The feeding mechanism 2 and the unloading mechanism 3 have the same structure, both including a support plate 21 horizontally fixed on the frame. A third motor 22 is provided at one end of the support plate 21, and a third lead screw 23 is connected to the shaft of the third motor 22. A second slider 24 is provided on the third lead screw 23, and a fixture 25 for placing the crystal ingot 100 is provided on the second slider 24. That is, the fixture 25 can move along the support plate 21 under the action of the second slider 24, and the direction of movement is perpendicular to the crossbeam 1. In other words, the direction of movement of the fixture 25 is perpendicular to the direction of movement of the conveying mechanism 6 along the crossbeam 1, thereby ensuring that the conveying mechanism 6 can clamp the crystal ingot 100 at any position on the feeding mechanism 2, and can also place the chamfered crystal ingot 100 at any position on the unloading mechanism 3.

[0039] The fixture 25 includes a fixture body with multiple (e.g., six) receiving slots for placing the crystal ingot 100. The cross-sectional shape of the receiving slots is the same as the cross-sectional shape of the crystal ingot 100, and the cross-sectional area of ​​the receiving slots is larger than the cross-sectional area of ​​the crystal ingot 100, ensuring that the crystal ingot 100 can be completely contained within the receiving slots. Loading or unloading into the receiving slots can be done manually.

[0040] like Figure 5 As shown, the chamfering mechanism 4 includes a mounting base 41 fixed on the frame, a sliding cylinder 42 on the mounting base 41, a chamfering motor 43 on the sliding cylinder 42, and a chamfering grinding wheel 44 on the chamfering motor 43. Preferably, the sliding cylinder 42 is a slide cylinder, the cylinder seat of the slide cylinder is connected to the mounting base 41, and the slide of the slide cylinder is connected to the chamfering motor 43 through a motor mounting plate 45. When chamfering is required, the slide cylinder drives the chamfering grinding wheel 44 to move towards the crystal ingot 100, and after chamfering is completed, it moves away from the crystal ingot 100, which facilitates subsequent unloading of the crystal ingot 100.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
