Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of brittle piece cracking, and particularly relates to a cracking device. BACKGROUND

[0002] When brittle pieces (such as glass, ceramic, silicon wafer, etc.) are laser cut, generally, cutting and cracking processes are needed. Laser cutting cuts a large piece into multiple small pieces, forming a cutting line on the large piece, but leaving about 0.5 mm of uncut excess. Then, the small pieces are completely cut or broken by cracking.

[0003] In the existing brittle piece cracking process, the laser head cuts the large piece completely along the cutting line on the large piece, and then the small pieces after cutting are sucked and discharged by the suction cup. This process has the problem of low efficiency, mainly because the large piece is usually cut into multiple small pieces (such as 12, 24 pieces, etc.). When multiple suction cups are used to batch suck the small pieces, the small pieces are easily dropped. The batch-sucked small pieces also need to be transferred through a transfer platform before being discharged and transported one by one. SUMMARY

[0044] Detailed Implementation

[0045] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0046] The dicing apparatus according to this application is described below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, this application provides a slicing device, which can be used for slicing large brittle parts. The slicing device includes independently arranged laser slicing module 200, slicing intermediate slicing module 400, large piece transfer module 101, slicing small piece module 500, and intermediate piece transfer module 102. The laser slicing module 200 has a laser assembly that forms a cutting layer within the large piece of material. The slicing intermediate slicing module 400 has a slicing intermediate slicing mechanism that breaks the large piece of material into intermediate pieces. The large piece transfer module 101 has a working end that transfers the large piece of material between the laser slicing module 200 and the slicing intermediate slicing module 400. The slicing small piece module 500 has a slicing small piece mechanism that breaks the intermediate piece of material into small pieces. The intermediate piece transfer module 102 has a working end that transfers the intermediate piece of material between the slicing intermediate slicing module 400 and the slicing small piece module 500.

[0048] It should be noted that the cleaving equipment of this application can be used for the cleaving process of brittle parts, including but not limited to glass, ceramics, silicon wafers, etc. The embodiments of this application take cleaved glass as an example for illustration.

[0049] The large glass is cut by laser, and a cutting line is formed on the large glass. However, in order to better control the cutting quality, reduce material waste, protect the performance of the glass, and adapt to the material characteristics, the large glass is not directly cut by laser, but about 0.5 mm of uncut margin is reserved. After the large glass is cut by laser, the whole large glass is fed to the laser cutting module 200. At the laser cutting module 200, the large glass is preliminarily cut along the cutting line (the margin is reduced, for example, so that the margin is reduced to 0.3 mm). Then, the large glass is moved to the position of the middle cutting module 400 by the large glass moving module 101. The large glass is cut in the X-axis direction by the middle cutting module, so that the large glass is cut into middle glass. Then, the middle glass is moved to the small glass cutting module 500 by the middle glass moving module 102. The middle glass is cut in the Y-axis direction by the small glass cutting module, so that the middle glass is cut into small glass. The small glass is directly discharged. In this scheme, the margin is reduced by laser cutting, and then the glass is cut into small pieces by mechanical cutting. The precision and yield of mechanical cutting can be improved. After the mechanical cutting, the glass is discharged in the form of small pieces, which is convenient for the construction of an automatic production line. In addition, the laser cutting and mechanical cutting are combined to improve the yield of cutting. The structures and actions of the modules are independent of each other. The modules are processed according to the time sequence. The whole glass is independently and continuously discharged in the form of single pieces. The efficiency is higher. Through the connection with the next process equipment, the flow line processing is realized.

[0050] In some embodiments, the cutting device further comprises a feeding module 300, the feeding module 300 comprising a first suction assembly 301, a first horizontal linear drive assembly 302, a first lifting linear drive assembly 303 and a first rotary drive 304 drivingly connected with the first suction assembly 301.

[0051] As shown in Figure 2 the first suction assembly 301 comprises a first suction disc, the first horizontal linear drive assembly 302 is a horizontal linear module, the first lifting linear drive assembly 303 is a lifting linear module, the lifting linear module is installed on the horizontal linear module, and the first rotary drive 304 can be a first rotary cylinder. The first rotary cylinder is installed on the side of the lifting linear module away from the horizontal linear module, and the first suction disc is installed at the lower end of the first rotary cylinder with the suction end downward. During feeding, the first suction disc suctions the whole glass, the first horizontal linear drive assembly 302 and the first lifting linear drive assembly 303 cooperate to drive the horizontal movement and the up-and-down movement of the first suction disc, and the rotation angle of the first suction disc after suctioning the glass is adjusted (the glass is rotated by 90 degrees) by the first rotary cylinder.

[0052] As shown in Figure 3As shown, the flaking equipment also includes a feeding module 100, which includes a first robotic arm 108, a transfer belt 103, and a second robotic arm 109. The first robotic arm 108 has a conveying end for moving small pieces of material between the flaking module 500 and the transfer belt 103, and the second robotic arm 109 has a conveying end for moving small pieces of material between the transfer belt 103 and the feeding position. The conveying ends of the first robotic arm 108 and the second robotic arm 109 are both located above the transfer belt 103. After the glass sharding module 500 shards the medium-sized glass into smaller pieces, the first robotic arm 108 moves its handling end to the discharge end of the glass sharding module 500 and transports the sharded glass pieces to the loading end of the transfer conveyor belt 103. The transfer conveyor belt 103 then runs, transporting the glass pieces from the loading end to the unloading end. The second robotic arm 109 moves to the unloading end of the transfer conveyor belt 103 and transports the glass pieces on the transfer conveyor belt 103 to the unloading position for unloading. In this embodiment, the entire process from sharding to unloading requires only two robotic arms and the transfer conveyor belt 103, achieving automated unloading without manual handling. This prevents damage to the glass during unloading and improves the yield of the final finished glass.

[0053] To improve the yield of finished glass, promptly detect defective products, and prevent defective products from being shipped out, a sampling robot and a sampling module are installed near the transfer conveyor belt 103. After the first robot 108 transports small pieces of glass onto the transfer conveyor belt 103, the sampling robot can extract several small pieces of glass during their transport on the belt, and the sampling module will then inspect them to ensure they meet the output quality requirements. The sampling module can utilize conventional sampling components from existing technologies, such as a flatness detector for checking the appearance flatness, or testing components for measuring dimensions; no specific limitations are imposed here.

[0054] like Figure 4 and Figure 5 As shown, both the first robotic arm 108 and the second robotic arm 109 include a second horizontal linear drive assembly 104, a second lifting linear drive assembly 105, a second adsorption assembly 106, and a second rotary drive component 107. The second lifting linear drive assembly 105 is slidably mounted on the second horizontal linear drive assembly 104. The second adsorption assembly 106 is mounted on the lower end of the second lifting linear drive assembly 105 and has a suction cup. The second rotary drive component 107 is rotaryly driven connected to the second adsorption assembly 106.

[0055] The second rotating driving member 107 is a second rotating cylinder, and the second adsorption assembly 106 is a second suction disc. The second horizontal linear driving assembly 104 and the first horizontal linear driving assembly 302 are similar in structure, and can adopt a horizontal linear module structure. The second lifting linear driving assembly 105 and the first lifting linear driving assembly 303 are similar in structure, and can also adopt a lifting linear module structure. When the small piece of glass is carried, the second lifting linear driving assembly 105 drives the second rotating driving member 107 to move downward together with the second adsorption assembly 106, the second rotating driving member 107 drives the second adsorption assembly 106 to rotate and adsorb the small piece of glass, and then the second horizontal linear driving assembly 104 drives the entire second lifting linear driving assembly 105 to move in the horizontal direction, so as to move to a suitable position above the transfer belt line 103.

[0056] In some embodiments, the laser splitting module 200 comprises a first positioning assembly, a laser cutting assembly 202 and a slag removal assembly 203. The first positioning assembly comprises a placing platform 201 on which a whole piece of glass to be split is placed. Limiting plates are arranged around the placing platform 201, and a plurality of limiting plates position the whole piece of glass on the placing platform 201 from all around. The laser cutting assembly 202 is located above the placing platform 201 and has a cutting end for laser cutting towards the large piece of material. The slag removal assembly 203 is arranged below the placing platform 201, and the slag removal assembly 203 comprises a slag collection barrel for collecting the slag falling from the placing platform 201.

[0057] As shown in Figure 6 The laser splitting module 200 mainly splits the large piece of glass along the cutting line to preliminarily split the large piece of glass (reduce the excess amount, for example, so that the excess amount is left with 0.3 mm). The feeding module 300 places the large piece of glass on the placing platform 201, and after a plurality of limiting plates mechanically position the large piece of glass, the laser cutting assembly 202 preliminarily splits the large piece of glass along the cutting line. The slag generated during the splitting can be collected and treated by the slag removal assembly 203 (i.e., the slag is collected by the slag collection tank below the placing platform 201. When the slag accumulates to a certain degree, the slag collection tank is moved to above the conveying belt below, the tank door at the lower end is opened to drop the slag onto the conveying belt, and the slag is output to the outside of the equipment by the conveying belt).

[0058] In some embodiments, the middle piece breaking mechanism and the small piece breaking mechanism are the same and the discharge direction is vertical, both including a positioning platform 41, a discharge platform 42, and a breaking unit; the discharge platform 42 is lower than the positioning platform 41, and a breaking corresponding port is formed between the positioning platform 41 and the discharge platform 42; the breaking unit includes a lower pressing breaking assembly 431 located above the discharge platform 42 and a pressing assembly 432 located above the positioning platform 41. The pressing assembly 432 is located above the positioning platform 41, and the pressing assembly 432 is used to press the second row of glass to flexibly press the whole piece of glass on the positioning platform 41; the lower pressing breaking assembly 431 is located above the discharge platform 42, presses the first row of glass, and breaks the first row of glass to fall on the discharge platform 42. The present application uses the pressing assembly 432 to flexibly press the glass, which is suitable for large plane fixation, and the pressing force can be controlled to prevent the glass from being damaged during the pressing process.

[0059] In some embodiments, as shown in Figure 7 and Figure 8 , the middle piece breaking mechanism and the small piece breaking mechanism both further include a rotary driving assembly, the rotary driving assembly is drivingly connected with the discharge platform 42, and the discharge platform 42 can be rotated to be obliquely connected with the positioning platform 41. The rotary driving assembly can be in the form of a rotary motor structure, the rotary shaft of the rotary motor is drivingly connected with the discharge platform 42, and when the rotary shaft rotates, the discharge platform 42 can be driven to rotate. When the material to be broken is broken, the material conveyed from the discharge end of the positioning platform 41 enters the discharge platform 42. Since the position of the discharge platform 42 is lower than that of the positioning platform 41, space is left for the breaking of the first row of glass, and then the discharge platform 42 is rotated so that the discharge platform 42 can be arranged in an inclined manner. After the first row of glass is broken by the lower pressing breaking assembly 431, the first row of glass is broken and falls. After one breaking is completed, the next row of glass to be broken is conveyed to the discharge platform 42, and the breaking operation is repeated until the whole piece of glass is broken. In the breaking process of the present application, the discharge platform 42 is lower than the positioning platform 41 and is obliquely connected, so that the lower pressing breaking assembly 431 can act on different positions of the material during the pressing process. Compared with the lower pressing mode acting on the fixed position of the material, it is more labor-saving, compared with the direct rotation breaking mode, it can avoid the poor cracking at the breaking position, and can improve the breaking yield of the material. Compared with the vacuum adsorption pressing mode in the prior art, the cooperation of the pressing assembly 432 and the lower pressing breaking assembly 431 can further improve the breaking yield of the material.

[0060] As shown in Figure 8 and Figure 9As shown, the crack middle piece mechanism and the crack small piece mechanism both further comprise a jacking conveying assembly 44 arranged below the positioning platform 41, the jacking conveying assembly 44 comprising a jacking piece 441, a first lifting driving assembly 442 drivingly connected with the jacking piece 441, and a first transverse moving linear module 443, the positioning platform 41 being provided with a passage opening through which the jacking piece 441 passes, the passage opening extending upwardly and downwardly through and to the corresponding breaking opening.

[0061] The jacking piece 441 comprises a bottom plate portion and two vertical portions arranged in parallel and spaced apart on the bottom plate portion, a negative pressure adsorption groove 444 for adsorbing glass being arranged on the top end face of the vertical portion, the negative pressure adsorption groove 444 being arranged along the length direction of the upper end face of the vertical portion, the number of the jacking pieces 441 being multiple and arranged in intervals, and the negative pressure adsorption groove 444 being in communication with an external vacuum adsorption member.

[0062] The first lifting driving assembly 442 comprises a jacking cylinder, the jacking cylinder realizing the lifting movement of the jacking piece 441; specifically, the driving end of the jacking cylinder is connected with the bottom end face of the jacking piece 441, when the piston rod of the jacking cylinder is extended or retracted, the jacking piece 441 can be moved up and down along the height direction, so as to realize the stable jacking of the jacking piece 441. When the jacking piece 441 is lifted upward, the vertical portion can be extended from the passage opening of the positioning platform 41 to lift the glass on the positioning platform 41, then the vacuum adsorption member is opened, and the negative pressure adsorption groove 444 on the jacking piece 441 is in negative pressure adsorption state to adsorb the bottom surface of the glass. Then the first transverse moving linear module 443 drives the jacking piece 441 to move transversely, so as to realize the transverse conveying of the glass, the whole transverse conveying process of the glass does not need manual participation, the efficiency is higher, and in the conveying process, the glass is carried by the adsorption of the negative pressure adsorption groove 444, so as to avoid damaging the glass in the conveying process, and improve the yield of the glass. Further, the end of the jacking cylinder away from the jacking piece 441 is installed on the first transverse moving linear module 443 through a jacking connecting plate, in order to realize the support stability of the jacking piece 441, a guide column is further connected between the jacking piece 441 and the jacking connecting plate, the outer periphery of the guide column is movably penetrated and connected with the jacking connecting plate through a linear bearing. The first transverse moving linear module 443 can be a conventional linear driving piece such as a transverse cylinder in the prior art.

[0063] In some embodiments, the lower pressing and breaking assembly 431 comprises a pressing roller and a lifting drive, the pressing roller is drivingly connected to the lifting drive. The pressing assembly 432 is arranged close to the breaking corresponding port and comprises a lower pressing drive 4321, an elastic member 4322 and a soft rubber pressing block 4323, the soft rubber pressing block 4323 is connected to the movable end of the lower pressing drive 4321 through the elastic member 4322. Wherein, the lifting drive comprises a lifting cylinder, the driving end of the lifting cylinder is connected with a protection frame, and the pressing roller is rotatably installed in the protection frame. Wherein, the lower pressing drive 4321 is a lower pressing cylinder, the piston rod of the lower pressing cylinder is connected with a first connecting plate, the side of the soft rubber pressing block 4323 facing the first connecting plate is provided with a second connecting plate, and the first connecting plate and the second connecting plate are connected with the elastic member 4322. Since the soft rubber pressing block 4323 is a flexible pressing block, when the piston rod of the lower pressing cylinder extends to drive the soft rubber pressing block 4323 to move downward and apply a downward pressure to the glass, the soft rubber pressing block 4323 will not damage the glass; since the elastic member 4322 is arranged between the soft rubber pressing block 4323 and the lower pressing cylinder, the existence of the buffering effect of the elastic member 4322 makes the downward pressure applied by the soft rubber pressing block 4323 to the glass more stable and gentle, thereby protecting the glass.

[0064] When the glass is broken, the soft rubber pressing block 4323 moves downward and flexibly presses the second row of glass, and the lifting cylinder drives the pressing roller to move downward to press and break the first row of glass, so that the large piece of glass can be broken along the cutting line. The breaking method of the present application can avoid scratching the glass and realize rapid breaking of the glass, thereby improving the breaking efficiency and yield.
