Description

Technical Field

[0001] The present application relates to the field of optical prism processing, and in particular to a prism chamfering device and a chamfering method. Background Art

[0002] The basic processing of optical prisms includes cutting, chamfering, grinding, coating and other processes. As products are now developing towards miniaturization and precision, optical prisms are also becoming smaller and more precise. Laser precision cutting has been achieved in the cutting process, but many optical prisms are tiny after cutting and are not easy to fix, so traditional equipment cannot perform chamfering.

[0003] There is a prism chamfering machine with a publication number of CN210998928U that automatically chamfers prisms, but the chamfering equipment can only chamfer a certain side edge of the prism, or use a flip mechanism to chamfer the same side edge of two oppositely arranged edges of the prism. When the prism has a need to chamfer both sides of the edge, the technical solution can only manually adjust the placement direction of the prism to meet the use requirements, and manual adjustment will cause errors in the chamfering of the two side edges of the prism. There is also an automatic chamfering device for optical glass with a publication number of CN113579907A, which directly uses a grinding piece to chamfer the edges of the prism on the basis of clamping. The problem with this is that the prism will be offset during the processing process, especially when processing small prisms, they are more affected by the vibration generated by grinding, resulting in large errors in the chamfering, which cannot meet the grinding requirements of small prisms with high precision.

[0087] Please refer to Figures 1 to 4The present embodiment provides a prism chamfering device, including a positioning mechanism 1, a clamping mechanism 2 and a chamfering mechanism 3. The positioning mechanism 1 includes a rotating component, a positioning component and a first storage table 11. The first storage table 11 is arranged on the rotating component. The rotating component can drive the first storage table 11 to rotate. The first storage table 11 is used to place the prism 5 to be processed. The positioning component includes a positioning end, and the positioning end is used to limit the prism 5 on the first storage table 11; the clamping mechanism 2 includes a clamping component and a first driving unit 23. The clamping component is used to clamp the prism 5 to be processed. The first driving unit 23 is used to drive the clamping component to move the prism 5 to be processed to the first storage table 11; the chamfering mechanism 3 includes a moving component and a grinding piece 31. The grinding piece 31 is arranged on the moving component. The moving component is used to drive the grinding piece 31 to move so as to chamfer the prism 5 to be processed on the first storage table 11.

[0088] The rotating assembly includes a first rotation drive unit 151 and a rotating platform 152. The first storage table 11 is arranged on the rotating platform 152. The first rotation drive unit 151 is used to drive the rotating platform 152 and the first storage table 11 to rotate. The first rotation drive unit 151 can be a motor or a rotary cylinder, etc. In the present embodiment, the first rotation drive unit 151 can be a DD motor. The DD motor is a high-precision, high-speed, high-torque outer rotor type that can directly drive the motor. It has the characteristics of low speed and high torque, can reduce energy output, and achieve the effect of precise angle control. The first storage table 11 and the rotating platform 152 can be detachably connected. Optionally, a plurality of first storage tables 11 can be provided according to the shapes of different prisms 5. When processing a certain prism 5, different first storage tables 11 are selected according to the shape of the prism 5.

[0089] Please refer to Figure 3 The positioning component includes a positioning end, which is used to limit the prism 5 on the first placement table 11. The positioning end can be set on the first placement table 11, for example, it can be a limit stopper. By setting the limit stopper on the circumference of the prism 5, the prism 5 is relatively fixed on the first placement table 11, which is convenient for the grinding piece 31 to chamfer. The positioning end can also be a limiter with a moving function. The first placement table 11 itself cooperates with the positioning end to achieve positioning when the prism 5 is chamfered, and is moved out after the prism 5 is chamfered, which is convenient for taking out and placing the prism 5.

[0090] In some preferred embodiments, the positioning component also includes a second visual sensor component 16, which is arranged directly above the first storage table 11. The second visual sensor component 16 includes a second light source and a second camera. The second camera takes a picture of the prism 5 to be positioned, and the second light source is used to increase the brightness of the prism 5, so that the picture taken by the second camera is clearer. The second camera compares the taken picture with the prism 5 picture stored in advance in the controller. The comparison includes: confirming the presence or absence of the prism 5, confirming whether the placement direction of the prism 5 meets the standard, and confirming the specific position of the side edge of the prism 5 to be chamfered (precisely positioning the side edge to facilitate the control of the direction of the grinding piece 31). When the placement direction of the prism 5 does not meet the standard (that is, the positioning end cannot be positioned according to the current placement direction of the prism 5), the clamping component is driven to re-clamp and place the prism 5 to meet the positioning requirements.

[0091] The clamping assembly can be a cylinder clamp or a suction cup, as long as it can clamp or suck the prism 5 to be processed. The clamping assembly is driven by the first drive unit 23 to move the prism 5 to be processed to the first storage table 11, so as to realize the automatic loading operation of the prism 5 to be processed. The first drive unit 23 can be a slide or a combination of a screw rod and a motor, as long as it has the function of moving. In this embodiment, considering that there are many processing parts of the prism 5, the size of the prism 5 to be processed is small, and there is a high precision requirement, the first drive unit 23 is implemented by a multi-axis robot.

[0092] In some preferred embodiments, the first driving unit 23 is further provided with a first visual sensor component 27, which includes a first light source and a first camera. The first camera takes a picture of the prism 5 to be clamped, and the first light source is used to increase the brightness of the prism 5 to be clamped, so that the picture taken by the first camera is clearer. The first camera compares the taken picture with the prism 5 picture stored in advance in the controller, and the comparison includes: confirming the presence or absence of the prism 5 and confirming the placement direction of the prism 5. Then the first driving unit 23 is operated to adjust the appropriate angle to clamp the prism 5 to be processed.

[0093] The chamfering mechanism 3 includes a moving assembly and a grinding piece 31. The grinding piece 31 is a tool for grinding, which can be a grinding wheel. The grinding wheel is also called a bonded abrasive. The grinding wheel is a bonded abrasive that is formed by bonding ordinary abrasives into a certain shape (mostly circular with a through hole in the center) and has a certain strength. It is generally composed of abrasives, bonding agents and pores, and these three parts are often called the three elements of bonded abrasives. According to the different classifications of bonding agents, common ones include ceramic (bonding agent) grinding wheels, resin (bonding agent) grinding wheels, and rubber (bonding agent) grinding wheels. In this embodiment, the grinding piece is made of a sintered diamond grinding wheel. The grinding wheel is the most widely used and widely used type of abrasive. It rotates at high speed when used, and can perform rough grinding, semi-fine grinding and fine grinding, as well as slotting and cutting, on the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces.

[0094] The mobile assembly specifically includes a first mobile platform assembly and a second mobile platform assembly. The second mobile platform assembly is arranged on the first mobile platform assembly, and the grinding member 31 is arranged on the second mobile platform assembly. Figure 4 In the figure, x represents the moving direction of the first mobile platform assembly, and y represents the moving direction of the second mobile platform assembly. Through the cooperation of the first mobile platform assembly and the second mobile platform assembly, the grinding part 31 can be moved within the plane where xy is located.

[0095] The first mobile platform assembly includes a first mobile slide rail, a first mobile drive unit 322 and a first mobile platform 321; the first mobile platform 321 is connected to the first mobile drive unit 322, the first mobile slide rail can be a cross-stick guide rail, and the first mobile drive unit 322 can be a motor. Through the cooperation between the first mobile slide rail and the first mobile drive unit 322, the sliding of the first mobile platform 321 can be realized to drive the second mobile platform assembly and the grinding part 31 to move along the x direction.

[0096] The second mobile platform assembly includes a second mobile slide rail, a second mobile drive unit 332 and a second mobile platform 331; the second mobile platform 331 is connected to the second mobile drive unit 332, the second mobile slide rail can be a cross-stick guide rail, and the second mobile drive unit 332 can be a motor. Through the cooperation between the second mobile slide rail and the second mobile drive unit 332, the sliding of the second mobile platform 331 can be realized to drive the grinding part 31 to move along the y direction.

[0097] The chamfering mechanism 3 further includes a grinding drive unit 34 and a second rotation drive unit 35. The output end of the grinding drive unit 34 is connected to the grinding member 31, and is used to drive the grinding member 31 to rotate, so that the end surface of the grinding member 31 is in a high-speed rotation state, and the end surface of the grinding member 31 contacts the side edge of the prism 5 to be processed, so as to achieve the chamfering action of the prism 5. In this embodiment, the grinding drive unit 34 can be a motor, and the second rotation drive unit 35 can be a rotating platform 152. The second rotation drive unit 35 is connected to the grinding drive unit 34 in a transmission manner. The second rotation drive unit 35 is used to drive the grinding drive unit 34 and the grinding member 31 to rotate a certain angle, so that the end surface of the grinding member 31 can be placed at a specific processing angle to chamfer the prism 5 to be processed. For example, when the angle of the edge chamfer is 30°, it is only necessary to adjust the inclination angle of the second rotation drive unit 35 to drive the grinding member 31 to rotate, so that the end surface of the grinding member 31 is placed at a 30° inclination angle, and the side edge of the prism 5 to be processed is chamfered by 30°.

[0098] As a preferred embodiment, a chamfering mechanism 3 has a grinding piece 31, and the number of chamfering mechanisms 3 can be multiple. When the number of chamfering mechanisms 3 is two, the two grinding pieces 31 are respectively arranged on both sides of the first storage table 11, and can simultaneously chamfer the two side edges of the prism 5 to be processed that are arranged opposite to each other, thereby improving the chamfering efficiency. Optionally, the chamfering of side edges of different heights can also be achieved by increasing the height of the chamfering mechanism 3. For example, when it is necessary to chamfer both the upper and lower edges of the cube prism 5, the chamfering mechanism 3 can be arranged at the location where the upper edge of the cube prism 5 is located and the lower edge is located, so that in one chamfering process, an upper edge and a lower edge that are parallel to each other can be chamfered at the same time, thereby improving the processing efficiency.

[0099] By providing a positioning mechanism 1 and a positioning end, and utilizing the cooperation between the positioning end and the first storage table 11, the positioning of the prism 5 to be processed during chamfering is achieved, thereby preventing the prism 5 to be processed from being offset due to the chamfering action of the grinding member 31, thereby causing a chamfering error; at the same time, by adding a rotating component, a grinding member 31 can be used to chamfer the side edges of the prism 5 in two different directions. During this process, the prism 5 is always placed on the first storage table 11, which can ensure that the reference position of the prism 5 does not change during chamfering, thereby ensuring the chamfering accuracy of the prism 5 and improving the chamfering efficiency of the prism 5.

[0100] Please refer to Figure 2 In some embodiments, the clamping assembly includes a first clamping assembly 21 and a second clamping assembly 22. The first clamping assembly 21 and the second clamping assembly 22 are driven by the same first driving unit 23, and the clamping timing of the first clamping assembly 21 and the second clamping assembly 22 is different.

[0101] The clamping assembly is used to clamp the prism 5. The clamping assembly can be a suction cup or a clamping claw. The clamping claw can be implemented by a clamping cylinder. According to the type of prism 5, a suitable clamping method is selected. For example, when the prism 5 is small in size and it is not suitable to be clamped by a clamping claw, it is preferably a suction cup negative pressure adsorption method, which is implemented by a small suction cup. When the prism 5 is large in size, it can be clamped by a suction cup negative pressure adsorption or a clamping claw. When the suction cup negative pressure adsorption is adopted, multiple suction cups can be equipped for adsorption, so that the adsorption force on the prism 5 is more uniform.

[0102] Please refer to Figure 2 In some embodiments, the clamping assembly includes a clamping arm 26, a clamping drive unit 25 and a second drive unit 24. The second drive unit 24 is arranged on the output end of the first drive unit 23. The clamping drive unit 25 is arranged on the output end of the second drive unit 24. The clamping arm 26 is arranged on the output end of the clamping drive unit 25. For example, the clamping drive unit 25 can be a clamping cylinder. The clamping arm 26 is arranged on two clamping claws of the clamping cylinder. The shape of the clamping arm 26 is designed according to the prism 5 to be clamped. It is arranged at the end of the clamping claw as an extension of the clamping claw, which is convenient for the clamping cylinder to clamp the irregular prism 5. The second drive unit 24 can be a telescopic cylinder, and the clamping drive unit 25 is fixed on the movable end of the telescopic cylinder. Then the clamping assembly can complete the two actions of telescoping and clamping, which is convenient for the clamping assembly to extend into the loading tray of the prism 5 to clamp the prism 5.

[0103] In this embodiment, the clamping assembly includes a first clamping assembly 21 and a second clamping assembly 22. The first clamping assembly 21 and the second clamping assembly 22 have the same structure and are used to clamp the same type of prism 5. However, the clamping timing of the first clamping assembly 21 and the second clamping assembly 22 is different, so as to improve the clamping efficiency of the prism 5. It can be understood in conjunction with the specific clamping process. For ease of distinction, in order of processing, the first prism 5 processed is called prism A, the second prism 5 processed is called prism B, the third prism 5 processed is called prism C, and the fourth prism 5 processed is called prism D: the first driving unit 23 can carry two prisms 5 in one drive, the first clamping component 21 clamps prism A, and the second clamping component 22 clamps prism B. However, there is only one first storage table 11, and only one prism 5 can be processed at a time. Therefore, the prism A on the first clamping component 21 is controlled to be placed on the first storage table 11 for processing first, and the second clamping component 22 always keeps the state of clamping prism B during the processing of prism A; after the prism A on the first clamping component 21 is processed, the first clamping component 21 clamps the prism A on the first storage table 11, and at this time, the prism B on the second clamping component 22 is placed on the first storage table 11. During the processing of prism B, the second clamping component 22 is empty, and together with the first clamping component 21 that clamps the processed prism A, it returns to the loading tray where the prism 5 is placed under the drive of the first driving unit 23. The first clamping component 21 puts prism A back on the tray. At the same time, the second clamping component 22 clamps another prism C to be processed. The first driving unit 23 drives the first clamping component 21 and the second clamping component 22 to return to the first storage table 11 together (the first clamping component 21 is empty during this process). At this time, the prism B on the original second clamping component 22 has been processed. The empty first clamping component 21 can clamp prism B and continue to put in the prism C to be processed on the second clamping component 22. Then, the first clamping component 21 clamps prism B and places it in the tray of the loading prism 5 under the drive of the first driving unit 23 (the corresponding second clamping component 22 is empty at this time). The second clamping component 22 synchronously clamps prism D during the process of the first clamping component 21 placing prism B, and so on.

[0104] By controlling the timing of the first clamping assembly 21 and the second clamping assembly 22 differently, the time for a single prism 5 to move back and forth between the first storage table 11 and the loading tray for collecting the prisms 5 after processing can be reduced. By alternately loading two prisms 5 at the same time, the action of clamping and placing one prism 5 can be achieved, so that the processing efficiency of multiple prisms 5 is significantly improved.

[0105] In some embodiments, the first clamping assembly 21 and the second clamping assembly 22 are detachably connected to the first driving unit 23. This facilitates timely replacement of the first clamping assembly 21 or the second clamping assembly 22 when it is damaged. At the same time, in some embodiments, the first storage table 11 can be provided with multiple types to be compatible with prisms 5 of various specifications. The first clamping assembly 21 and the second clamping assembly 22 can also be equipped with multiple types to facilitate matching with the shape specifications of the prism 5 processed on the first storage table 11. The detachable connection facilitates the replacement of the first clamping assembly 21 and the second clamping assembly 22 to meet the use requirements of prisms 5 of different specifications.

[0106] Please refer to Figure 5 In some embodiments, the prism chamfering equipment also includes a transfer mechanism 4, which includes a second storage table 41 and a second cleaning device 42. The prism 5 to be processed is placed on the second storage table 41. The second cleaning device 42 includes an inlet pipe, an outlet pipe and a first collecting tank. The outlet of the inlet pipe is connected to the second storage table 41; the inlet of the outlet pipe is connected to the second storage table 41; the outlet of the outlet pipe is connected to the first collecting tank, and the first collecting tank is used to collect waste water.

[0107] The second storage table 41 is mainly used to place the prism 5 to be processed, but it is different from the first storage table 11. The first storage table 11 is used to place the prism 5 during the grinding process. In this embodiment, the prisms 5 are processed one by one. Therefore, only a single prism 5 to be processed can be placed on the first storage table 11. The second storage table 41 is used to place multiple prisms 5 to be processed. In some preferred embodiments, the prism 5 is placed in the loading tray of the prism 5 when loading. The second storage table 41 can be used to place the loading tray of the prism 5. In this way, there is no need to transfer the prisms 5 from the loading tray to the second storage table 41 one by one, saving this transfer step, thereby improving the loading efficiency of the prism 5.

[0108] In some preferred embodiments, the transfer mechanism 4 further includes a transfer drive unit 43 and a transfer slide rail 44. The output end of the transfer drive unit 43 is connected to the second storage platform 41. The second storage platform 41 is provided on the transfer slide rail 44. The transfer drive unit 43 may be a motor. By adding the transfer drive unit 43, the second storage platform 41 can be moved to the edge of the device relative to the bottom plate of the device. The worker only needs to put the prism 5 tray into the edge of the chamfering device. The second storage platform 41 moves the prism 5 into the device for loading by the clamping mechanism 2, thereby avoiding the worker from loading materials illegally when the clamping mechanism 2 is clamping, and also improving the portability of the worker loading materials.

[0109] In some embodiments, in order to save the loading time of the prism 5, two second storage tables 41 can be added. In this way, when the prism 5 on one of the second storage tables 41 is chamfered, it is possible to quickly switch to the other second storage table 41 to load the prism 5, saving the time waiting for manual loading and improving the processing efficiency of the prism 5.

[0110] The surface of the prism 5 is easy to be attached with impurities, especially in the process of processing the prism 5, if there is no dust removal device, the prism 5 is very easy to be scratched or adhered by the debris generated by the processing, which affects the quality of the prism 5. In this embodiment, a second cleaning device 42 is provided to solve the above problem. The second storage table 41 includes two parts, one is a soaking tank 412, and the other is a lifting tray 411. The lifting tray 411 is arranged in the soaking tank 412 and can be raised and lowered relative to the soaking tank 412. The outlet of the water inlet pipeline is connected to the soaking tank 412 on the second storage table 41, so that the soaking tank 412 always maintains a certain liquid level height of the liquid. The water outlet pipeline is arranged at the bottom of the soaking tank 412, which is used to collect the debris in the soaking tank 412 and discharge the wastewater in the soaking tank 412. The first collection tank is used to collect the wastewater and debris discharged from the soaking tank 412. A filtering device can be added to the discharge port of the first collection tank to filter and reuse the wastewater, improve the recycling rate of water resources, and save energy and protect the environment. In this embodiment, the liquid in the soaking tank 412 is not limited to water, but can also be specially prepared decontaminated water or clean water. For example, it can be prepared from various preparations of surfactants (such as sodium alkylbenzene sulfonate, sodium fatty alcohol sulfate), and auxiliary agents. When washing dirt on the surface of the prism 5, the surface tension of the aqueous solution can be reduced.

[0111] The specific use process is as follows: the lifting tray 411 is raised to a height higher than the liquid level in the soaking tank 412, and then the worker places the prism 5 placed in the prism 5 loading tray and the prism 5 loading tray together in the lifting tray 411, and the lifting tray 411 then drives the prism 5 loading tray to descend together to make the liquid immerse the upper surface of the prism 5, and the surface of the prism 5 is cleaned by immersion, which can also prevent the prism 5 from being stained with dust while waiting for processing. Optionally, the water inlet and outlet pipes can be controlled to open synchronously to realize the flow of liquid in the soaking tank 412 and improve the cleaning efficiency of the prism 5.

[0112] The clamping assembly can be directly extended into the soaking tank 412 to clamp the prism 5. When the prism 5 is clamped by gas adsorption such as a suction cup, the lifting tray 411 can be controlled to lift the upper surface of the prism 5 slightly above the liquid level to facilitate the clamping of the suction cup. During the suction cup clamping process, the suction cup can also be controlled to blow air first to blow away the liquid and dust on the upper surface of the prism 5, so that the clamping effect of the suction cup is better.

[0113] By providing the second storage table 41 and the second cleaning device 42, it is possible to prevent dust from sticking to the prism 5 to be processed while other prisms 5 are being processed and waiting. At the same time, the prism 5 can also be cleaned to keep the surface of the prism 5 clean. The second storage table 41 can also be placed in the loading tray of the prism 5 to facilitate workers to load the materials.

[0114] In some embodiments, the prism 5 to be processed includes a first side edge and a second side edge, and the first side edge does not overlap with the second side edge; the rotating component can be placed in a first rotation position or a second rotation position, and when the rotating component is placed in the first rotation position, the grinding member 31 chamfers the first side edge of the prism 5 to be processed; when the positioning mechanism is placed in the second rotation position, the grinding member 31 chamfers the second side edge of the prism 5 to be processed.

[0115] The first side edge and the second side edge of the prism 5 to be processed do not overlap, which means that the first side edge and the second side edge can be two adjacent side edges or two side edges arranged in parallel. By utilizing the rotating action of the rotating assembly, the effect of one grinding piece 31 chamfering the side edges of the prism 5 in multiple directions one by one can be achieved without manual adjustment, thereby improving the efficiency of chamfering the prism 5. At the same time, during this chamfering process, the prism 5 is always placed on the first storage table 11 and does not move, so the reference edge of the prism 5 is always unified during the processing, thereby making the processing accuracy of the prism 5 higher.

[0116] Please refer to Figure 6 In some embodiments, the positioning assembly includes a first positioning assembly, the first positioning assembly includes a third driving unit 121 and a first positioning end 122; the first positioning end 122 is arranged on the output end of the third driving unit 121, and the third driving unit drives the first positioning end 122 to perform telescopic movement along the first direction; a first limiting portion 111 is provided on the first placement table 11 along the first direction, and the first limiting portion 111 is used to limit the prism 5 to be processed on the first placement table 11 along the first direction, and a first limiting portion 111 is provided on the first limiting portion 111 Through hole 114; when in the first rotation position, the first positioning component can be placed in the first stop position or the first loose position under the drive of the third driving unit 121. When the first positioning component is placed in the first stop position, the first positioning end 122 is driven by the third driving unit 121 to fit with the side of the prism 5 to be processed, and the first positioning end 122 passes through the first through hole 114 and stops on the prism 5. When the first positioning component is placed in the first loose position, the first positioning end 122 is driven by the third driving unit 121 to separate from the side of the prism 5 to be processed.

[0117] The prism 5 includes a third prism 53, and the third prism 53 is a long strip prism 5, that is, a prismatic prism 5. For example, in this embodiment, the third prism 53 selected is a strip hexahedral prism 5 with a rectangular radial cross section. Here, the first direction is Figure 6direction a shown in .

[0118] The first positioning assembly includes a first positioning end 122, which can be made into an L shape, one side of the first positioning end 122 is connected to the output end of the third drive unit 121, and the third drive unit 121 can be a cylinder; the other end of the first positioning end 122 is in the same horizontal plane as the third prism 53 placed on the first storage table 11. In some preferred embodiments, when the first positioning end 122 is stopped on the third prism 53, the height of the first positioning end 122 is lower than the height of the third prism 53, so as to avoid interference with the processing tool during the processing. Optionally, the first positioning assembly also includes a first connecting member, one side of the first connecting member is connected to the output end of the third drive unit 121, and the other side of the first connecting member is detachably connected to the first positioning end 122, so as to facilitate the disassembly and replacement of the first positioning end 122 when it is worn.

[0119] In this embodiment, the first placement platform 11 is used to place the long strip prism 5 (i.e., the third prism 53), so the shape of the first placement platform 11 is preferably designed to be rectangular, and the size needs to just accommodate the third prism 53. A first limiting portion 111 is provided on the first placement platform 11, and the first limiting portion 111 is arranged on the first placement platform 11 along a first direction. Here, the first direction refers to a direction parallel to the longer side of the first placement platform 11, that is, a direction parallel to the length direction of the third prism 53. The first limiting portion 111 is used to limit the offset direction of the third prism 53 in the first direction.

[0120] The third driving unit 121 can drive the first positioning end 122 to perform telescopic movement along the first direction, and the positioning of the prism 5 is achieved by driving the first positioning end 122 to approach the prism 5 and stop on the prism 5. When the third prism 53 is positioned in the first direction, the third driving unit 121 drives the first positioning end 122 to move forward, and the other side parallel to the side is stopped on the first limiting portion 111 on the other side under the push of the first positioning end 122. At this time, the first positioning end 122 stops on the side of the third prism 53, and a clamping space is formed between the first positioning end 122 and the first limiting portion 111, and the third prism 53 is fixed in the clamping space. At this time, the first positioning assembly is placed in the first stopping position. Taking the chamfering process as an example, when the third prism 53 is in the first stopping position, the grinding member 31 can chamfer the edges of the third prism 53 in the length direction. Preferably, the double-sided grinding member 31 can be used to chamfer the two edges of the third prism 53 in the length direction to improve the chamfering efficiency. After the chamfering process is completed, the third driving unit 121 drives the first positioning end 122 away from the side of the third prism 53, and the first positioning assembly is in the first loose position. When the two edges on the other side need to be chamfered in actual needs, the rotating table can drive the third prism 53 to rotate to another direction along the direction of the arrow for subsequent chamfering processes.

[0121] There are two first limiting portions 111, which are arranged opposite to each other along the first direction. The spacing between the two first limiting portions 111 should be slightly larger than the length of the third prism 53, so as to facilitate the placement of the third prism 53. The first limiting portion 111 arranged on the side where the first positioning end 122 is located will block the first positioning end 122 from abutting against the side of the third prism 53. At this time, the first through hole 114 is opened on the first limiting portion 111, that is, the position where the first through hole 114 is opened should be on the same side as the first positioning end 122. At the same time, the first positioning end 122 should be smaller than the size of the first through hole 114, so that the first positioning end 122 can pass through the first through hole 114 and abut against the side of the third prism 53, thereby achieving better restriction of the third prism 53 on the first storage table 11, while satisfying the need for the first positioning end 122 to cooperate with the first limiting portion 111 to clamp the third prism 53.

[0122] In some preferred embodiments, in order to expand the contact area between the first positioning end 122 and the side of the third prism 53, thereby generating a larger resistance force and better fixing the third prism 53, the first positioning end 122 can be set to a U-shape as shown in the figure. When the first positioning end 122 passes through the first through hole 114 and resists on the side of the third prism 53, two resistance fulcrums will be generated, and the distribution of the resistance force will also change from the lower position of the side of the third prism 53 to the distribution on the side of the third prism 53 from bottom to top two-thirds, so that the force on the third prism 53 is balanced, and the resistance force is prevented from being excessively concentrated on the lower part of the third prism 53, causing the third prism 53 to tilt during the resistance process, thereby affecting the processing accuracy.

[0123] Please refer to Figure 7 , the b direction in the figure represents the second direction. In some embodiments, the first positioning assembly further includes a fourth driving unit 123 and a second positioning end 124; the second positioning end 124 is arranged on the output end of the fourth driving unit 123, and the fourth driving unit 123 drives the second positioning end 124 to perform telescopic movement along the second direction; a second limiting portion 112 is provided on the first placement table 11 along the second direction, and the second limiting portion 112 is used to limit the prism 5 to be processed on the first placement table 11 along the second direction, and a second through hole 115 is provided on the second limiting portion 112; in the second rotation position, the first positioning assembly can be placed in the second stop position or the second loose position under the drive of the fourth driving unit 123, when the first positioning assembly is placed in the second stop position, the second positioning end 124 is driven by the fourth driving unit 123 to fit with the side of the prism 5 to be processed, and the second positioning end 124 passes through the second through hole 115 and stops on the prism 5, when the first positioning assembly is placed in the second loose position, the second positioning end 124 is driven by the fourth driving unit 123 to separate from the side of the prism 5 to be processed.

[0124] The fourth drive unit 123 is arranged on one side of the first storage table 11. In some embodiments, the fourth drive unit 123 is arranged opposite to the third drive unit 121, which is convenient for saving space, more simple and beautiful. The first positioning assembly includes a second positioning end 124, the second positioning end 124 can be made into an L shape, one side of the second positioning end 124 is connected to the output end of the fourth drive unit 123, and the fourth drive unit 123 can be a cylinder; the other end of the second positioning end 124 is in the same horizontal plane as the third prism 53 placed on the first storage table 11. In some preferred embodiments, when the second positioning end 124 is stopped on the third prism 53, the height of the second positioning end 124 is lower than the height of the third prism 53, avoiding interference with the processing tool during the processing. Optionally, the first positioning assembly also includes a second connecting member, one side of the second connecting member is connected to the output end of the fourth drive unit 123, and the other side of the second connecting member is detachably connected to the second positioning end 124, so as to facilitate the disassembly and replacement of the second positioning end 124 when it is worn.

[0125] In this embodiment, a second limiting portion 112 is provided on the first placement platform 11. The second limiting portion 112 is arranged on the first placement platform 11 along the second direction. Here, the second direction refers to a direction parallel to the shorter side of the first placement platform 11, that is, a direction parallel to the width direction of the third prism 53. The second limiting portion 112 is used to limit the offset direction of the third prism 53 in the second direction. The second limiting portion 112 and the first limiting portion 111 are both arranged on the first placement platform 11. The second limiting portion 112 is arranged adjacent to the first limiting portion 111, and the second limiting portion 112 and the first limiting portion 111 form a certain angle. The size of the angle corresponds to the angle between the long edge and the side edge of the third prism 53. For example, when the third prism 53 is a regular hexagonal prism, the angle between the first limiting portion 111 and the second limiting portion 112 should be 120°. In this embodiment, the third prism 53 is a square prism, so when the first limiting portion 111 and the second limiting portion 112 are arranged adjacent to each other, the first limiting portion 111 and the second limiting portion 112 form an angle of 90°. The second limiting portion 112 can be arranged on one side of the first limiting portion 111, forming an L-shaped angle with the first limiting portion 111, and the second positioning end 124 should be arranged on the side opposite to the second limiting portion 112. Preferably, the second limiting portion 112 is arranged on both sides of the first limiting portion 111, forming a U-shaped angle, for limiting the rotation of the third prism 53 in the second direction. The fourth driving unit 123 can drive the second positioning end 124 to perform telescopic movement along the second direction, and the positioning of the prism 5 is achieved by driving the second positioning end 124 to approach the prism 5 and stop on the prism 5.

[0126] When positioning the third prism 53 in the second direction, the fourth driving unit 123 drives the second positioning end 124 forward, and the other side parallel to the side is pushed by the second positioning end 124 to stop on the second limiting portion 112 on the other side. At this time, the second positioning end 124 stops on the side of the third prism 53, and a clamping space is formed between the second positioning end 124 and the second limiting portion 112, and the third prism 53 is fixed in the clamping space. At this time, the first positioning assembly is placed in the second stopping position. When the third prism 53 is in the second stopping position, the grinding member 31 can chamfer the edges of the third prism 53 in the width direction. Preferably, the two-sided grinding member 31 can be used to chamfer the two edges of the third prism 53 in the width direction to improve the chamfering efficiency. After the chamfering process is completed, the fourth driving unit 123 drives the second positioning end 124 away from the side of the third prism 53, and the first positioning assembly is in the second loose position. When it is actually necessary to chamfer the two edges on the other side, the rotating table can drive the third prism 53 to rotate to another direction for subsequent chamfering process. For example, it can be rotated to the first direction, and the first positioning end 122 cooperates with the first limiting portion 111 to fix the third prism 53 in the first direction, and then the chamfering work in the first direction can be performed.

[0127] When the number of the second limiting parts 112 is two, the second limiting parts 112 are arranged in the second direction to limit the displacement of the third prism 53 along the second direction, and the second limiting part 112 arranged on the side where the second positioning end 124 is located will block the second positioning end 124 from abutting against the side of the third prism 53. At this time, the second through hole 115 is provided on the second limiting part 112, that is, the position where the second through hole 115 is provided should be on the same side as the second positioning end 124, and at the same time, the second positioning end 124 should be smaller than the size of the second through hole 115, so that the second positioning end 124 can pass through the second through hole 115 and abut against the side of the third prism 53, thereby achieving better limiting of the third prism 53 on the first placement table 11, while meeting the requirement that the second positioning end 124 cooperates with the second limiting part 112 to clamp the third prism 53.

[0128] In some preferred embodiments, in order to expand the contact area between the second positioning end 124 and the side of the third prism 53, thereby generating a larger resistance force and better fixing the third prism 53, the end of the second positioning end 124 that contacts the prism 53 can also be set to Figure 7The horizontal U-shape shown in the figure will generate a total of four stopping points when the second positioning end 124 passes through the second through hole 115 and stops on the side of the third prism 53. The distribution of the stopping force will also change from the lower position of the side of the third prism 53 to the distribution at the position of two-thirds from bottom to top of the side of the third prism 53. This makes it easier to balance the force on the third prism 53 and avoids excessive concentration of the stopping force on the lower part of the third prism 53, which will cause the third prism 53 to tilt during the stopping process, thereby affecting the processing accuracy.

[0129] By setting the second positioning end 124 and the fourth driving unit 123, and utilizing the cooperation between the second limiting portion 112 and the second positioning end 124, the third prism 53 is limited in the second direction, which facilitates the processing operation of the third prism 53; at the same time, the second positioning end 124, the first positioning mechanism 1 and the second positioning end 124, the second positioning mechanism 1 are equipped to realize automatic positioning of the prism 5 in the first direction and the second direction and directional adjustment between the first direction and the second direction, saving the time of manual adjustment, and at the same time can realize the precise positioning of the prism 5 and reduce the processing error.

[0130] Please refer to Figure 8 In some embodiments, the positioning assembly further includes a second positioning assembly, the second positioning assembly includes a fifth driving unit 131 and a third positioning end 132, the third positioning end 132 is arranged on the output end of the fifth driving unit 131, and the fifth driving unit drives the third positioning end 132 to perform telescopic movement along the height direction. The prism 5 includes a fourth prism 54, and the fourth prism 54 is a block prism 5. For example, in this embodiment, the fourth prism 54 selected is a cube prism 5. The first placement table 11 is used to place the fourth prism 54, and the fourth prism 54 is different from the third prism 53. It should be noted that the structure of the first placement table 11 in this embodiment is different in structure from the first placement table 11 on which the third prism 53 is placed. Please refer to Figure 8 A third limiting portion 113 is provided on the first placement table 11 on which the fourth prism 54 is placed along the height direction. The third limiting portion 113 is used to limit the prism 5 to be processed on the first placement table 11 along the height direction. A third through hole 116 is provided on the third limiting portion 113. One end of the third through hole 116 is connected to the negative pressure generator and is used to adsorb the prism 5 to be processed by negative pressure. The second positioning component can be placed in a third abutting position or a third loosening position under the drive of the fifth driving unit 131. When the second positioning component is placed in the third abutting position, the third positioning end 132 is driven by the fifth driving unit 131 to fit the upper surface of the prism 5 to be processed, and the lower surface of the prism 5 is stopped on the third limiting portion 113. When the second positioning component is placed in the third loosening position, the third positioning end 132 is driven by the fifth driving unit 131 to separate from the upper surface of the prism 5 to be processed.

[0131] The second positioning assembly includes a third positioning end 132, which can be made into an L shape, one side of the third positioning end 132 is connected to the output end of the fifth driving unit 131, and the fifth driving unit 131 can be a cylinder; the other end of the third positioning end 132 is at the same height direction as the fourth prism 54 placed on the first storage table 11. Optionally, the second positioning assembly also includes a third connecting member, one side of the third connecting member is connected to the output end of the fifth driving unit 131, and the other side of the third connecting member is detachably connected to the third positioning end 132, so that the third positioning end 132 can be disassembled and replaced when it is worn.

[0132] The first placement table 11 is provided with a third limiting portion 113, and the fourth prism 54 is placed on the third limiting portion 113. Through the clamping space formed in the height direction by the third limiting portion 113 and the third positioning end 132, the fourth prism 54 is clamped in the height direction, so that the processing equipment can process the fourth prism 54 in the circumferential direction. Figure 8 The arrow direction in the figure indicates the adsorption direction of the third through hole 116. The third through hole 116 passes through the rotating platform 152 and the first storage platform 11. The negative pressure generator is arranged below the rotating platform 152 and communicates with the third through hole 116 through an air pipe. The third through hole 116 has a negative pressure, which can adsorb the fourth prism 54 on the third limit portion 113 to prevent the fourth prism 54 from rotating relative to the third limit portion 113. During the processing of the side edges of the fourth prism 54, it is very easy for the grinding member 31 to interfere with the first storage platform 11 or the third limit portion 113, or even the third positioning end 132. In order to reduce the interference between the grinding member 31 and other positioning parts, the four edges of the lower surface of the fourth prism 54 all protrude from the third limit portion 113; the four edges of the upper surface of the fourth prism 54 all protrude from the third positioning end 132, which is convenient for processing, avoiding the third positioning end 132 and the third limit portion 113 from being worn during the chamfering process, and damaging the grinding member 31.

[0133] By providing the third limiting portion 113 and the third positioning end 132, the processing positioning of the fourth prism 54 is achieved, and the chamfering of the circumferential side edges of the upper and lower surfaces of the fourth prism 54 can be achieved without flipping the fourth prism 54 during the processing, thereby improving the chamfering efficiency of the fourth prism 54. The technical solution provided in this embodiment can be used not only for chamfering the edges of the cubic prism 5, but also for chamfering the circumferential side edges of the block prism 5 having two upper and lower parallel planes, such as the block prism 5 with a hexagonal radial cross section.

[0134] In some embodiments, the positioning mechanism 1 also includes a first cleaning device 14, which includes at least one water spray pipe 141, a second collecting trough 142, a guide pipe and a sedimentation tank. The water outlet of the water spray pipe 141 is aligned with the prism 5 to be processed on the first storage table 11; the second collecting trough 142 is used to collect debris and sewage dropped by the prism 5 to be processed during the processing, and the first storage table 11 is placed in the second collecting trough 142; the guide pipe is arranged in the second collecting trough 142, and the guide pipe is used to discharge the sewage in the second collecting trough 142; the sedimentation tank is connected to one end of the guide pipe, and a drain outlet and a sewage outlet are provided on the sedimentation tank, and the height of the drain outlet is higher than the sewage outlet.

[0135] During the chamfering process, there is wear between the grinding piece 31 and the prism 5, which will produce wear debris. If the debris is not removed in time, the debris will adhere to the surface of the prism 5 during the chamfering process, scratching the surface of the prism 5 or affecting the chamfering accuracy of other edges. Therefore, a dust removal device is required to remove dust from the prism 5 being processed. There are two ways of dust removal: gas dust removal and liquid dust removal. In this embodiment, the liquid dust removal method is used, which can not only achieve the dust removal effect of the prism 5, but also cool the prism 5 being processed to avoid uneven heating and fragmentation of the prism 5. The effect of liquid cooling is more significant than that of gas cooling.

[0136] The first cleaning device 14 includes at least one water spray pipe 141, and multiple water spray pipes 141 can be equipped according to the size of the prism 5. The water outlet of the water spray pipe 141 should be aligned with the prism 5 to be processed on the second storage table 41. The second collection tank 142 is used to collect the debris and sewage dropped by the prism 5 to be processed during the processing. The first storage table 11 is placed in the second collection tank 142. As a preferred embodiment, the tank wall of the second collection tank 142 is higher than the first storage table 11, so that the splashes of the prism 5 during the processing can be blocked by the tank wall of the second collection tank 142 to avoid flying out of the second collection tank 142 and affecting the surrounding electrical components. The guide pipe is arranged in the second collection tank 142. Optionally, the guide pipe is preferably arranged at the bottom of the second collection tank 142 to discharge the sewage in the second collection tank 142. During the processing, the chamfering of the prism 5 generates a lot of debris. Therefore, a sedimentation tank is added to precipitate wastewater, and the precipitated wastewater flows out from the drain port, and the precipitated sludge flows out from the sewage outlet. By setting up separate outlets, it is convenient for workers to process the discharged sludge. At the same time, the precipitated wastewater can be reused through a filtering and circulating mode to save water resources. In this embodiment, the liquid in the soaking tank 412 is not limited to water, but can also be specially prepared decontaminated water or clean water. For example, it can be prepared from various preparations of surfactants (such as sodium alkylbenzene sulfonate, sodium fatty alcohol sulfate), and auxiliary agents. When washing the dirt on the surface of the prism 5, the surface tension of the aqueous solution can be reduced.

[0137] By providing the first cleaning device 14, it is possible to avoid the situation in which debris adheres to the surface of the prism 5 and scratches the surface of the prism 5 or affects the chamfering accuracy of other edges during the chamfering process, and at the same time, the prism 5 being processed can be cooled.

[0138] Please refer to Fig. 9 This embodiment also provides a prism chamfering method, which is applied to the prism chamfering device mentioned above, and includes the following steps:

[0139] S11, the first driving unit 23 drives the clamping assembly to move the prism 5 to be processed on the first placement table 11 to a first predetermined position, and places the prism 5 to be processed on the first placement table 11;

[0140] S12, the rotating assembly drives the first placement table 11 to rotate so that the prism 5 to be processed is placed at a predetermined angle in a state to be processed;

[0141] S13 , the moving assembly drives the grinding member 31 to move so as to chamfer the prism 5 to be processed at a predetermined angle on the first placement table 11 .

[0142] The first predetermined position indicates the loading position of the prism 5. In actual operation, the prisms 5 are placed on the loading tray in batches, and the first driving unit 23 clamps the prisms 5 on the loading tray one by one and moves them to the first storage table 11 for chamfering. The rotating assembly drives the first storage table 11 to rotate, so that the prism 5 to be processed is placed at a predetermined angle in the processing state. For example, when the side edge of the upper surface of the cube prism 5 is chamfered, one side of the cube prism 5 can be processed first, and then the rotating assembly first drives the cube prism 5 to rotate 90° to chamfer the adjacent side edge, and then continues to rotate 90° to chamfer the next side edge, and so on. In some embodiments, still taking the cube prism 5 as an example, if the side edge of the prism 5 in the vertical direction needs to be chamfered, the rotating assembly first drives the first storage table 11 to rotate 45°, so that one side edge of the prism 5 in the vertical direction is aligned with the grinding piece 31, and then the grinding piece 31 is used to chamfer it.

[0143] This method is applicable to the prism chamfering device mentioned above. Through the cooperation of the rotating component, the first storage table 11 and the grinding piece 31, one grinding piece 31 can chamfer the side edges of the prism 5 in two different directions, thereby improving the chamfering efficiency of the prism 5 while ensuring the chamfering accuracy.

[0144] Please refer to Fig.10In some embodiments, the clamping assembly includes a first clamping assembly 21 and a second clamping assembly 22, the first clamping assembly 21 and the second clamping assembly 22 are driven by the same first driving unit 23, and the clamping timing of the first clamping assembly 21 and the second clamping assembly 22 is different; the prism 5 to be processed includes a first prism 51 and a second prism 52; the first clamping assembly 21 can be placed in a first clamping position and a first placement position, and the second clamping assembly 22 can be placed in a second clamping position or a second placement position;

[0145] Methods include:

[0146] S01, the first driving unit 23 drives the first clamping assembly 21 and the second clamping assembly 22 to move synchronously to a first predetermined position, and controls the first clamping assembly 21 and the second clamping assembly 22 to be placed in a clamping position to clamp the first prism 51 and the second prism 52 respectively;

[0147] S02, when the first clamping assembly 21 and the second clamping assembly 22 move to the position of the first placement table 11, the first clamping assembly 21 is controlled to be in the first placement position and the second clamping assembly 22 is controlled to maintain the second clamping position, so that the first prism 51 is placed on the first placement table 11;

[0148] S03, after the first prism 51 is processed, the first clamping assembly 21 is controlled to be in the first clamping position and the second clamping assembly 22 is controlled to maintain the second placement position, so that the second prism 52 is placed on the first placement table 11;

[0149] S04, the first driving unit 23 drives the first clamping assembly 21 and the second clamping assembly 22 to move synchronously to the first predetermined position, controls the first clamping assembly 21 to be in the first placement position to put the processed first prism 51 back to the first predetermined position, and controls the second clamping assembly 22 to be in the second clamping position to clamp the next prism 5 to be processed located at the first predetermined position;

[0150] S05, the first driving unit 23 drives the first clamping assembly 21 and the second clamping assembly 22 to move synchronously to the position of the first storage table 11 again, controls the first clamping assembly 21 to be in the first clamping position to clamp the processed second prism 52, and controls the second clamping assembly 22 to be in the second placement position to place the next prism 5 to be processed on the first storage table 11.

[0151] In this embodiment, the first prism 51 and the second prism 52 have the same structure and are the same type of prism 5. In step S02, the second clamping assembly 22 always clamps the second prism 52 while the first prism 51 is being processed. In step S03, when the first clamping assembly 21 is in the first clamping position, it means that the first clamping assembly 21 clamps and removes the processed first prism 51 from the first storage table 11.

[0152] In step S04, the first clamping assembly 21 puts the first prism 51 that has been processed back to the first predetermined position (i.e., the loading tray of the prism 5), and the second clamping assembly 22 simultaneously clamps another prism 5 in the loading tray when the first clamping assembly 21 places the first prism 51, so as to save the time of successively clamping the prisms 5. Step S05 indicates that after the second prism 52 is processed, the first clamping assembly 21 clamps the second prism 52 and takes it out from the first storage table 11, and the second clamping assembly 22 places another prism 5 on the first storage table 11, and so on.

[0153] By adopting the alternate loading and unloading method, the loading and unloading time of the prism 5 is overlapped with the processing time of the prism 5 , thereby shortening the loading and unloading time of the prism 5 and improving the processing efficiency of the prism 5 .

[0154] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
