[0042] The present application provides a processing device. In order to make the skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0043] As shown in Figures 1-5 , the processing device provided by the present application comprises a turnover mechanism 100, an illuminating mechanism 200 and a vision mechanism (not shown in the figure).

[0044] The turnover mechanism 100 comprises a mounting bracket, a turnover assembly mounted on the mounting bracket and a connecting assembly, the connecting assembly is used for connecting a product to be processed, and the turnover assembly is used for overturning the connecting assembly and the product to be processed connected by the connecting assembly, so as to overturn the current target processing surface of the product to be processed connected by the connecting assembly to a preset processing position.

[0045] The illuminating mechanism 200 is located below the turnover mechanism 100.

[0046] The vision mechanism is located above the turnover mechanism 100, and the vision mechanism is used for acquiring position information of the product to be processed connected by the turnover mechanism 100.

[0047] When the above-mentioned processing device processes the product, the illuminating mechanism 200 provides a suitable lighting environment, and the vision mechanism acquires the position information of the product to be processed connected by the turnover mechanism 100. According to the position information acquired by the vision mechanism, it can be judged whether the current target processing surface is in the preset processing position. If it is not in the preset processing position, the turnover assembly can be started to drive the product to rotate until the current target processing surface of the product reaches the preset processing position, without the need to remove the product from the turnover mechanism 100, adjust the angle and then place it on the turnover mechanism 100 (i.e. without the need to pour the material), which saves the pouring time and avoids the damage to the product caused by the pouring process, thus improving the processing efficiency and product yield. In addition, the vision mechanism, the turnover mechanism 100 and the illuminating mechanism 200 are arranged in an up-down manner, so that the processing device occupies a small area.

[0048] For example, if the product is a semiconductor wafer, the processing apparatus can be a cleaver. When it is necessary to perform front-side cleaving on the wafer, the front side of the wafer is rotated to an upward position; when it is necessary to perform back-side cleaving on the wafer, the back side of the wafer is rotated to an upward position. It should be noted that the processing apparatus provided in this application is not limited to semiconductor processing.

[0049] In some embodiments, reference is made to Figure 6 The lighting mechanism 200 includes a light source 201, a light source bracket 202, and a lifting power component 203. The light source 201 is connected to the light source bracket 202. The light source bracket 202 is guided and engaged with the mounting frame of the flipping mechanism 100 (guided and engaged with the base plate 103 of the mounting frame in the figure). The lifting power component 203 is used to drive the light source bracket 202 to rise and fall relative to the mounting frame, so as to move the light source 201 closer to or away from the product connected to the flipping mechanism 100. With this design, before the flipping mechanism 100 flips the product, the lifting power component 203 can be activated to drive the light source 201 down to a position that does not interfere with the product flipping. After the target processing surface of the product is flipped to the preset processing position, the lifting power component 203 can be activated again to drive the light source 201 up to a position close to the product.

[0050] Specifically, in the illustrated embodiments, such as Figure 6 As shown, the light source bracket 202 includes an upper support plate 202a, a guide post 202b, and a lower support plate 202c. The guide post 202b connects the upper support plate 202a and the lower support plate 202c. The guide post 202b is inserted into a guide hole on the mounting bracket of the flipping mechanism 100. More specifically, when the mounting bracket has a base plate 103, the guide hole can be set on the base plate 103. The light source 201 is connected to the upper support plate 202a. The lifting power component 203 is a cylinder, including a cylinder body and a cylinder rod. The cylinder rod is connected to the mounting bracket. More specifically, when the mounting bracket has a base plate 103, the cylinder rod can be connected to the base plate 103 of the mounting bracket, and the cylinder body is connected to the lower support plate 202c. After the lifting power component 203 is activated, the cylinder body moves up and down relative to the cylinder rod, driving the lower support plate 202c to move up and down, thereby driving the entire light source bracket 202 and the light source 201 to move up and down together.

[0051] In actual implementation, the structure of the light source bracket 202 is not limited to the illustrated embodiment, as long as it can connect the light source 201 and the lifting power component 203 and can cooperate with the guide of the mounting frame. The lifting power component 203 is not limited to a cylinder; for example, it can also be a hydraulic cylinder or a motor. The positions of the cylinder body and cylinder rod can be interchanged; for example, the cylinder body is connected to the base plate 103 of the mounting frame, and the cylinder rod is connected to the lower support plate 202c.

[0052] In some embodiments, such as Figure 2As shown, the processing device further comprises a code scanning mechanism 300, which comprises a code scanner 301 and a code scanner support 302. The code scanner 301 is connected to the code scanner support 302, and the code scanner support 302 is connected to the mounting frame of the turnover mechanism 100. The code scanner 301 is used to scan and identify the identification code on the surface of the product, so as to identify the surface of the product currently located at the preset processing position. If the surface of the product currently located at the preset processing position is not the target processing surface, the turnover power member 104 of the turnover mechanism 100 is started to turn over the product until the target processing surface is located at the preset processing position.

[0053] In some embodiments, the code scanning mechanism 300 comprises a plurality of code scanners 301, each of which is located at a different position of the first connecting assembly A and the second connecting assembly B. When the turnover mechanism 100 turns over the product to different positions, the same identification code on the surface of the product can be scanned and identified by different code scanners 301, so as to identify the surface of the product currently located at the preset processing position according to the position of the code scanner 301 currently scanning and identifying the identification code. Alternatively, the code scanning mechanism 300 can also comprise only one code scanner 301, which is used to scan and identify different identification codes on different surfaces of the product to identify the surface of the product currently located at the preset processing position.

[0054] In the illustrated embodiment, as shown in Figure 2 The code scanning mechanism 300 is provided with one code scanner 301 above and below the product 01 connected by the first connecting assembly A and the second connecting assembly B. For example, if the product is a semiconductor wafer, when the code scanner 301 above scans the identification code on the front surface of the semiconductor wafer, it means that the front surface of the semiconductor wafer is upward, and when the code scanner 301 below scans the identification code on the front surface of the semiconductor wafer, it means that the front surface of the semiconductor wafer is downward.

[0055] In the illustrated embodiment, as shown in Figures 2-5 The code scanner support 302 corresponding to the code scanner 301 above comprises a horizontal support arm 302c, which spans above the first support 101 and the second support 102. The horizontal support arm 302c is provided with one vertical support arm 302d at each end, and the bottom ends of the two vertical support arms 302d are connected to the top ends of the first support 101 and the second support 102, respectively. The code scanner 301 above is connected to the middle of the horizontal support arm 302c. The code scanner support 302 corresponding to the code scanner 301 below comprises a horizontal shaft 302a, which spans between the first support 101 and the second support 102. The horizontal shaft 302a is provided with one adapter arm 302b at each end, and the two adapter arms 302b are connected to the third supporting part 101b of the first support 101 and the fourth supporting part 102b of the second support 102, respectively. The code scanner 301 below is connected to the middle of the horizontal shaft 302a. This form of code scanner support does not interfere with the rotation of the product.

[0056] In actual implementation, the form of the code scanner support 302 is not limited to the illustrated embodiment, as long as it can be connected with the mounting frame of the turnover mechanism 100 and the code scanner 301 and does not interfere with the rotation of the product.

[0057] In some embodiments, as shown in Figure 7 The turnover assembly includes a first turnover assembly C and a second turnover assembly D, and the connecting assembly includes a first connecting assembly A and a second connecting assembly B. The first connecting assembly A and the second connecting assembly B are connected to the two sides of the product respectively. The first turnover assembly C is connected to the first connecting assembly A to turn the first connecting assembly A. The second turnover assembly D is connected to the second connecting assembly B to turn the second connecting assembly B.

[0058] In some embodiments, the first turnover assembly C includes a turnover power member 104 and a first transmission part, and the second turnover assembly D includes a second transmission part. The turnover power member 104 is connected to the first transmission part. The first transmission part is connected to the first connecting assembly A. The first transmission part is connected to the second transmission part. The second transmission part is connected to the second connecting assembly B, so that the turnover power member 104 drives the first connecting assembly A and the second connecting assembly B to rotate synchronously.

[0059] In the illustrated embodiment, the turnover power member 104 is a rotary motor. As shown in Figure 2 and Figure 3 The first transmission part includes a first pulley assembly 105, a second pulley assembly 106, a first transmission shaft 108, and a second transmission shaft 109. As shown in Figure 4 and Figure 5 The second transmission part includes a third pulley assembly 107, a third transmission shaft 110, and a fourth transmission shaft 111.

[0060] The first pulley assembly 105, the second pulley assembly 106, and the third pulley assembly 107 each include at least an input wheel, an output wheel, and a transmission belt wound around the input wheel and the output wheel. A tension pulley can also be optionally provided.

[0061] As shown in Figure 8 and Figure 9As shown, the rotary motor is drivingly connected with the first transmission shaft 108 through the first pulley assembly 105, and the first transmission shaft 108 is drivingly connected with the first connecting assembly through the second pulley assembly 106. In the illustrated embodiment, the rotary output shaft of the rotary motor is coaxially connected with the input pulley of the first pulley assembly 105, the output pulley of the first pulley assembly 105 is coaxially connected with the first transmission shaft 108, and the first transmission shaft 108 serves as the output shaft of the first pulley assembly 105. The output pulley of the second pulley assembly 106 is connected with the first connecting assembly A through the second transmission shaft 109. After the rotary motor is started, power is transmitted from the rotary output shaft of the rotary motor to the input pulley of the first pulley assembly 105, then to the output pulley of the first pulley assembly 105, then to the input pulley of the second pulley assembly 106 through the first transmission shaft 108, then to the output pulley of the second pulley assembly 106, and then to the first connecting assembly A through the second transmission shaft 109, thereby driving the first connecting assembly A to rotate.

[0062] As shown in FIG. 1, the first connecting assembly A is connected with the second connecting assembly B through the turnover power member 104. In the illustrated embodiment, the turnover power member 104 is a rotary cylinder. The first transmission shaft 108 is drivingly connected with the second connecting assembly B through the third pulley assembly 107. In the illustrated embodiment, the input pulley of the third pulley assembly 107 is coaxially connected with the third transmission shaft 110. One end of the third transmission shaft 110 is coaxially connected with one end of the first transmission shaft 108 through a shaft coupling 112. Alternatively, the first transmission shaft 108 and the third transmission shaft 110 can be the same shaft. The output pulley of the third pulley assembly 107 is connected with the second connecting assembly B through the fourth transmission shaft 111. After the rotary motor is started, power is transmitted from the rotary output shaft of the rotary motor to the input pulley of the first pulley assembly 105, then to the output pulley of the first pulley assembly 105, then to the input pulley of the third pulley assembly 107 through the first transmission shaft 108 and the third transmission shaft 110, then to the output pulley of the third pulley assembly 107, and then to the second connecting assembly B through the fourth transmission shaft 111, thereby driving the second connecting assembly B to rotate. Figure 10 Figure 11 As shown, the first transmission shaft 108 is drivingly connected with the second connecting assembly B through the third pulley assembly 107. In the illustrated embodiment, the input pulley of the third pulley assembly 107 is coaxially connected with the third transmission shaft 110. One end of the third transmission shaft 110 is coaxially connected with one end of the first transmission shaft 108 through a shaft coupling 112. Alternatively, the first transmission shaft 108 and the third transmission shaft 110 can be the same shaft. The output pulley of the third pulley assembly 107 is connected with the second connecting assembly B through the fourth transmission shaft 111. After the rotary motor is started, power is transmitted from the rotary output shaft of the rotary motor to the input pulley of the first pulley assembly 105, then to the output pulley of the first pulley assembly 105, then to the input pulley of the second pulley assembly 106 through the first transmission shaft 108, then to the output pulley of the second pulley assembly 106, and then to the second connecting assembly B through the fourth transmission shaft 111, thereby driving the second connecting assembly B to rotate.

[0063] The above structure realizes the synchronous rotation of the first connecting assembly A and the second connecting assembly B with only one motor, and is simple, reliable, and low in cost.

[0064] In actual implementation, the turnover power member 104 can only provide rotary driving force, for example, a rotary cylinder can also be used. The first transmission part and the second transmission part can only transmit rotary driving force to the first connecting assembly A and the second connecting assembly B, for example, a chain wheel assembly or a gear assembly can also be used.

[0065] ​In some embodiments, the turnover mechanism comprises a mounting frame, two sides of the mounting frame are provided with a first support 101 and a second support 102, the first connecting assembly A is installed on the upper part of the first support 101 close to one side of the second support 102, the first pulley assembly 105 is installed on the lower part of the first support 101 close to one side of the second support 102, the second pulley assembly 106 is installed on the side of the first support 101 away from the second support 102, the first transmission shaft 108 and the second transmission shaft 109 are rotatably inserted into the first support 101, the second connecting assembly B is installed on the upper part of the second support 102 close to one side of the first support 101, the third pulley assembly 107 is installed on the side of the second support 102 away from the first support 101, the third transmission shaft 110 and the fourth transmission shaft 111 are rotatably inserted into the second support 102. In this way, the first pulley assembly 105, the second pulley assembly 106 and the third pulley assembly 107 do not interfere with the rotation of the first connecting assembly A, the second connecting assembly B and the product, and the overall layout is compact, so that the overall volume of the turnover mechanism 100 is small.

[0066] In the illustrated embodiment, the first turnover assembly C and the second turnover assembly D are also respectively provided with a first cover 123 and a second cover 124. The first cover 123 is connected to the side of the first support 101 away from the second support 102, covering the second pulley assembly 106. The second cover 124 is connected to the side of the second support 102 away from the first support 101, covering the third pulley assembly 107.

[0067] The mounting frame can also be optionally provided with a bottom plate 103. The bottom plate 103 is fixed to the bottom ends of the first support 101 and the second support 102, so that the first support 101 and the second support 102 are connected together through the bottom plate 103, making the entire turnover mechanism 100 a whole, thereby facilitating installation and transportation. In addition, at least one of the first support 101 and the second support 102 can be optionally allowed to slide relative to the bottom plate 103 to adjust the distance between the first support 101 and the second support 102, more precisely, to adjust the distance between the first connecting assembly A and the second connecting assembly B, so that the first connecting assembly A and the second connecting assembly B can cooperate to connect products of different sizes. Specifically, when connecting smaller size products, the distance between the first connecting assembly A and the second connecting assembly B is reduced, and when connecting larger size products, the distance between the first connecting assembly A and the second connecting assembly B is increased.

[0068] In the illustrated embodiment, the first support 101 and the second support 102 can both slide relative to the bottom plate 103, so that when adjusting the distance between the first support 101 and the second support 102, the first support 101 and the second support 102 can be simultaneously moved closer or simultaneously moved away, so that the distance between the first support 101, the second support 102 and the center of the bottom plate 103 can always remain consistent.

[0069] In the illustrated embodiment, the bottom plate 103 is provided with a long hole 103a, and the first support 101 and the second support 102 are connected to the bottom plate 103 through threaded fasteners passing through the long hole 103a. After the threaded fasteners are loosened, the first support 101 and the second support 102 can slide along the length direction of the long hole 103a, and after the threaded fasteners are tightened, the first support 101 and the second support 102 are fixed relative to the bottom plate 103.

[0070] In actual implementation, the structure of fixing and relative sliding between the first support 101, the second support 102 and the bottom plate 103 is not limited to the long hole 103a and the threaded fasteners described above. For example, a slide rail and a slide block can be provided on the bottom plate 103, the first support 101 and the second support 102 are fixed to the slide block, a plurality of spring connecting pins are sequentially and spacedly arranged along the length direction of the slide rail, and when the slide block slides to a position corresponding to a spring connecting pin along the length direction of the slide rail, the slide block is fixed under the stop action of the corresponding spring connecting pin.

[0071] In the illustrated embodiment, as shown in Figure 12 and Figure 13 , the first connecting assembly A and the second connecting assembly B each include a clamping power member 113 and two mutually cooperating clamping plates E. The clamping plates E are connected to the clamping power member 113 through a connecting block 116. The clamping power member 113 drives the two mutually cooperating clamping plates E to approach each other to clamp a product or to move away from each other to release the product. When connecting a product, one side of the product is located between and clamped by the two clamping plates E of the first connecting assembly A, and the other side of the product is located between and clamped by the two clamping plates E of the second connecting assembly B.

[0072] In actual implementation, the first connecting assembly A and the second connecting assembly B are not limited to the clamping structure described above, as long as they can ensure that the connected product does not fall off during rotation. For example, the first connecting assembly A and the second connecting assembly B can also be a suction cup structure. The clamping power member 113 can be a pneumatic cylinder, a hydraulic cylinder, a motor, etc.

[0073] In the illustrated embodiment, the first connecting assembly A and the second connecting assembly B each further include a limiting assembly 117, which includes a limiting block 117a and a limiting screw 117b. When the two mutually cooperating clamping plates E move away from each other to the limit, the two clamping plates E abut against the limiting screw 117b, that is, the limiting screw 117b limits the limit of the two mutually cooperating clamping plates E. By adjusting the screwing depth of the limiting screw 117b relative to the limiting block 117a, the limit of the two mutually cooperating clamping plates E can be adjusted.

[0074] In the illustrated embodiment, as shown in Figure 14As shown, a plurality of elastic centering units 118 are connected between the two clamping plates E of the first connecting assembly A and between the two clamping plates E of the second connecting assembly B. The elastic centering units 118 of the first connecting assembly A are arranged in sequence along the first direction, and the elastic centering units 118 of the second connecting assembly B are also arranged in sequence along the first direction. As shown, Figure 7 As shown, the first direction is perpendicular to the interval arrangement direction of the first connecting assembly A and the second connecting assembly B.

[0075] The two clamping plates E of the first connecting assembly A and the two clamping plates E of the second connecting assembly B each have a clamping surface 114a for contacting the product. The elastic centering units 118 of the first connecting assembly A are located on the side of the clamping surface 114a of the clamping plate E of the first connecting assembly A away from the second connecting assembly B, and the elastic centering units 118 of the second connecting assembly B are located on the side of the clamping surface 114a of the clamping plate E of the second connecting assembly B away from the first connecting assembly A.

[0076] When the two sides of the product are located between the two clamping plates E of the first connecting assembly A and between the two clamping plates E of the second connecting assembly B respectively, the two side edges of the product are in contact with the elastic centering units 118 of the first connecting assembly A and the elastic centering units 118 of the second connecting assembly B respectively, and the elastic centering units 118 of the first connecting assembly A and the elastic centering units 118 of the second connecting assembly B cooperate to center the product between the first connecting assembly A and the second connecting assembly B.

[0077] Specifically, as shown, Figure 15 As shown, the elastic centering unit 118 at least includes a rotating member (118a in the figure), a guide member (118c in the figure), and an elastic member 118d. The surface of the rotating member is used for rolling contact with the side edge of the product, and the rotating member can play a conveying role and will not scratch the product when the product enters and exits the gap between the two clamping plates E. The guide member guides the rotating member to move towards the product or away from the product relative to the clamping plate E, and when the rotating member moves away from the product, it presses the elastic member 118d, so that the compression amount of the elastic member 118d increases.

[0078] In the illustrated embodiment, the rotating member of the elastic centering unit 118 is a bearing 118a, which is rotatably connected to a sliding block 118b (connected by a screw 118e in the figure), and the outer peripheral surface of the bearing 118a is used for contacting the side edge of the product. The guide member is a guide rod 118c, and the sliding block 118b is slidably sleeved on the outer periphery of the guide rod 118c, and the sliding block 118b is slid along the guide rod 118c to drive the bearing 118a to slide towards the product or away from the product. The elastic member 118d is arranged between the sliding block 118b away from the product and the clamping plate E.

[0079] In actual implementation, the rotating member of the elastic centering unit 118 is not limited to the bearing 118a, and the guide member is not limited to the guide rod 118c. For example, the rotating member can also be a ball, and the guide member can also be a ball slide pre-formed on the clamping plate E.

[0080] If the product is inclined to the first connecting assembly A, the bearing 118a of the elastic centering unit 118 of the first connecting assembly A will slide in a direction away from the product, so that the sliding block 118b compresses the elastic member 118d, and the bearing 118a of the elastic centering unit 118 of the first connecting assembly A will slide in a direction close to the product under the elastic force of the elastic member 118d, thereby pushing the product to move to the second connecting assembly B, so as to realize the centering of the product.

[0081] Similarly, if the product is inclined to the second connecting assembly B, the bearing 118a of the elastic centering unit 118 of the second connecting assembly B will slide in a direction away from the product, so that the sliding block 118b compresses the elastic member 118d, and the bearing 118a of the elastic centering unit 118 of the second connecting assembly B will slide in a direction close to the product under the elastic force of the elastic member 118d, thereby pushing the product to move to the first connecting assembly A, so as to realize the centering of the product.

[0082] In the illustrated embodiment, as shown in Figure 12 , each of the two cooperating clamping plates E is connected with six elastic centering units 118 (as can be seen from Figure 12 the guide rods 118c of the twelve elastic centering units 118), and the elastic centering units 118 connected to one of the two cooperating clamping plates E are staggered with the elastic centering units 118 connected to the other clamping plate E in the first direction. In actual implementation, only one of the two cooperating clamping plates E can be connected with the elastic centering units 118. Figure 13 As shown in , the clamping power member 113 is provided with a shaft hole 113a for connecting a transmission shaft.

[0083] Figure 14 In the illustrated embodiment, as shown in , the two cooperating clamping plates E are provided with grooves 114b located on the side of the clamping surface 114a away from the product. The grooves 114b are used to accommodate the elastic centering units 118, which not only can accommodate the elastic centering units 118 connected to the clamping plate E where the groove 114b is located, but also can accommodate the elastic centering units 118 connected to the other clamping plate E cooperating with the clamping plate E where the groove 114b is located, that is, when the two cooperating clamping plates E clamp the product, the elastic centering units 118 connected to one of the two clamping plates E can enter the groove 114b of the other clamping plate E.

[0084] Figure 14As shown, the clamping plate E is provided to include a clamping plate body 114 and a clamping plate cover 115 assembled with the clamping plate body 114, the recess 114b and the clamping surface 114a are both provided on the clamping plate body 114, the opening of the recess 114b far away from the clamping surface 114a is closed by the clamping plate cover 115. One end of the guide rod 118c is inserted into the clamping plate body 114 and the other end is inserted into the clamping plate cover 115, so as to facilitate the assembly of the elastic centering unit 118 and the clamping plate E. When assembling, the elastic centering unit 118 can be assembled with the clamping plate body 114 first, and then the clamping plate cover 115 is assembled. Specifically, the connection between the clamping plate cover 115 and the clamping plate body 114 is preferably a detachable connection, so as to facilitate the replacement of the elastic centering unit 118. For example, the clamping plate cover 115 and the clamping plate body 114 can be connected by clamping or threaded fasteners.

[0085] In the illustrated embodiment, as shown in Figure 8 As shown, the two clamping plates E of the first connecting assembly A form a product inlet (indicated by I in the figure) between one end and a product outlet (indicated by X in the figure) between the other end. As shown in Figure 10 The two clamping plates E of the second connecting assembly B form a product inlet (indicated by I in the figure) between one end and a product outlet (indicated by X in the figure) between the other end. The product enters the gap between the two clamping plates E from the product inlet, which is called product feeding. The product leaves the gap between the two clamping plates E from the product outlet, which is called product discharging. In this way, product feeding and product discharging can be carried out at the same time, which is more conducive to improving the efficiency of product connection.

[0086] In the illustrated embodiment, the turnover mechanism 100 further comprises a product feeding guide and a product discharging guide. The product feeding guide and the product discharging guide are installed on the mounting frame. The product feeding guide is used to guide the product to enter the gap between the two clamping plates E from the product inlet in parallel, and the product discharging guide is used to guide the product to leave the gap between the two clamping plates E in parallel, so as to avoid the product being scratched by the two clamping plates E during feeding and discharging.

[0087] In the illustrated embodiment, as shown in Figures 8-11 The product feeding guide comprises a first guide rail 119 and a second guide rail 120, and the product discharging guide comprises a third guide rail 121 and a fourth guide rail 122. The two sides of the first support 101 are respectively provided with a first supporting portion 101a and a third supporting portion 101b, and the first supporting portion 101a and the third supporting portion 101b respectively support and fix the first guide rail 119 and the third guide rail 121.
