Description

Technical Field

[0001] This application relates to the field of processing equipment technology, specifically to a transition device and processing system. Background Technology

[0002] In general, the processing flow of various workpieces (such as circuit boards) requires the workpieces to be transferred between different devices in the processing system. However, due to unreasonable design of the processing system, the workpieces may not be transferred correctly. Summary of the Invention

[0003] This application provides a transition device and a processing system. When the transition device is applied to the processing system, it can ensure that the workpiece is smoothly transferred on the processing system.

[0004] In a first aspect, this application provides a transition device for assisting in the transfer of a workpiece between a first device and a second device, the transition device comprising:

[0005] A first guiding component includes a first sub-component and a second sub-component, the first sub-component and the second sub-component together forming a connected first opening and a second opening; and

[0006] A driving component is used to drive a first guide component to move, thereby changing the size of the first opening and the second opening; when the first opening increases under the drive of the driving component, the second opening decreases under the drive of the driving component, and the first opening is used to guide a positioning element on the workpiece to the second opening; when the second opening increases under the drive of the driving component, the first opening decreases under the drive of the driving component, and the second opening is used to guide a positioning element on the workpiece to the first opening.

[0007] The first sub-component and the second sub-component are connected. The first sub-component can transmit motion to the second sub-component, or the second sub-component can transmit motion to the first sub-component, so that the size of the first opening and the second opening can be changed jointly by the first sub-component and the second sub-component.

[0008] The first sub-component includes a first guide block and a first transmission member connected to each other, and the second sub-component includes a second guide block and a second transmission member connected to each other. The first guide block and the second guide block are spaced apart and together form the first opening and the second opening. The first transmission member and the second transmission member are connected to each other so that the first sub-component and the second sub-component rotate synchronously.

[0009] The transition device further includes a second guide component, which includes a third sub-component and a fourth sub-component. The third sub-component and the fourth sub-component together form a connected third opening and a fourth opening, and the third opening faces the second opening. The driving component is also used to drive the second guide component to change the size of the third opening and the fourth opening. The third opening increases or decreases synchronously with the first opening, and the fourth opening increases or decreases synchronously with the second opening.

[0010] The third sub-component and the fourth sub-component are connected. The third sub-component can transmit motion to the fourth sub-component, or the fourth sub-component can transmit motion to the third sub-component, so that the size of the third opening and the fourth opening can be changed jointly by the third sub-component and the fourth sub-component.

[0011] The third sub-component includes a third guide block and a third transmission component connected together, and the fourth sub-component includes a fourth guide block and a fourth transmission component connected together. The third guide block and the fourth guide block are spaced apart and together form the third opening and the fourth opening. The third transmission component and the fourth transmission component are connected in cooperation to make the third sub-component and the fourth sub-component rotate synchronously.

[0012] The transition device further includes a connecting rod, which is connected to the first guide assembly and the second guide assembly to enable the first guide assembly and the second guide assembly to move synchronously.

[0013] The transition device further includes a support for supporting the workpiece. The support has a guide channel, one end of which is connected to a second opening of the first guide component, and the other end of which is connected to a third opening of the second guide component.

[0014] The transition device further includes a blocking assembly, which includes a driving member and a blocking member connected to each other. The driving member is used to drive the blocking member to move so that the blocking member is located in the extension direction from the first opening to the second opening. The blocking member is used to obstruct the positioning member on the workpiece.

[0015] Secondly, this application also provides a processing system, which includes a first device, a second device, and the aforementioned transition device. The transition device is at least partially disposed between the first device and the second device to assist in the transfer of workpieces between the first device and the second device.

[0016] The transition device provided in this application includes a first guide assembly and a drive assembly. The first guide assembly has a first opening and a second opening that are connected to each other. The drive assembly is used to drive the first guide assembly to change the size of the first opening and the second opening. The first opening and the second opening have opposite trends in increasing and decreasing; that is, when the first opening increases, the second opening decreases, and vice versa. It is understood that the increased size of the first opening (or second opening) facilitates the entry of a positioning element on the workpiece and guides the positioning element into the decreased size of the second opening (or first opening). The decreased size of the second opening (or first opening) can limit the movement direction of the workpiece to prevent deviation by the positioning element, thereby regulating the transfer movement of the workpiece and ensuring that the workpiece can be accurately and smoothly transferred between the first device and the second device.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] Please refer to Figures 1 to 2This application provides a processing system 100, which includes a first device 1, a second device 2, and a transition device 3. The transition device 3 is at least partially disposed between the first device 1 and the second device 2 to assist in the transfer of a workpiece 200 between the first device 1 and the second device 2.

[0040] The first device 1 may be, but is not limited to, a loading / unloading device. Loading refers to placing the workpiece 200 to be processed onto the loading / unloading device, and unloading refers to removing the processed workpiece 200 from the loading / unloading device. Therefore, the loading / unloading device is a device used to carry both the workpiece 200 to be processed and the processed workpiece 200. The second device 2 may be, but is not limited to, a processing device, which is a device used to process the workpiece 200 to be processed.

[0041] The workpiece 200 needs to be transferred between the first device 1 and the second device 2. The transition device 3 is similar to a bridge to transfer the workpiece 200 from the first device 1 to the second device 2, or from the second device 2 to the first device 1.

[0042] Please refer to Figure 3 and Figure 4 The workpiece 200 includes a plate 4 and a positioning element 5. The positioning element 5 is fixedly connected to the plate 4. The plate 4 can be, but is not limited to, a printed circuit board (PCB), a mobile phone case, etc. During the conveying process, the plate 4 is supported by the transition device 3. The positioning element 5 is used to position the plate 4 during the conveying process to ensure that the movement of the plate 4 does not deviate from the set path.

[0043] The transition device 3 in the processing system 100 provided in the above embodiment will be described in detail below with reference to the accompanying drawings.

[0044] Please refer to Figures 5 to 8 This application provides a transition device 3 for assisting the transfer of workpiece 200 between a first device 1 and a second device 2. The transition device 3 includes a first guide component 31 and a drive component 33, which are described below.

[0045] The first guide component 31 includes a first sub-component 311 and a second sub-component 312. The first sub-component 311 and the second sub-component 312 together form a first opening K1 and a second opening K2 that are connected.

[0046] The driving component 33 is used to drive the first guide component 31 to move, thereby changing the size of the first opening K1 and the second opening K2. When the first opening K1 increases under the drive of the driving component 33 (e.g. Figure 7As shown), the second opening K2 shrinks under the drive of the drive assembly 33, and the first opening K1 is used to guide the positioning element 5 on the workpiece 200 to the second opening K2. When the second opening K2 expands under the drive of the drive assembly 33 (e.g. Figure 8 As shown), the first opening K1 shrinks under the drive of the drive assembly 33, and the second opening K2 is used to guide the positioning member 5 on the workpiece 200 to the first opening K1.

[0047] Specifically, the first opening K1 is adjacent to the first device 1, and the second opening K2 is adjacent to the second device 2. Optionally, the arrangement direction of the first opening K1 and the second opening K2 is consistent with the arrangement direction of the first device 1 and the second device 2. In other embodiments, the arrangement direction of the first opening K1 and the second opening K2 may also be inclined to the arrangement direction of the first device 1 and the second device 2, that is, the workpiece 200 is conveyed at an angle.

[0048] The driving component 33 can drive the first guiding component 31, causing the size of the first opening K1 and the second opening K2 to change, and the two changes in opposite trends, that is, when the first opening K1 increases, the second opening K2 decreases, and when the first opening K1 decreases, the second opening K2 increases.

[0049] The enlarged first opening K1 (or second opening K2) is in an open state, which facilitates the entry of the positioning element 5 on the workpiece 200. The reduced first opening K1 (or second opening K2) is in a limited state, which limits the position of the positioning element 5.

[0050] During the process of transferring workpiece 200 from the first device 1 to the second device 2, it needs to pass through the first opening K1 and the second opening K2 in sequence. During this process, the first opening K1 is in an open state, and the second opening K2 is in a closed state. Since the first opening K1 is in an open state, the positioning element 5 on the workpiece 200 can easily enter the first opening K1 and be guided by the first opening K1 to the second opening K2. Since the second opening K2 is in a closed state, the positioning element 5 on the workpiece 200 is confined within the narrow second opening K2. Thus, the movement direction of the workpiece 200 is not deviated through the second opening K2, ensuring that the workpiece 200 can be transferred to the designated position on the second device 2.

[0051] Similarly, during the process of transferring workpiece 200 from the second device 2 to the first device 1, it needs to pass through the second opening K2 and the first opening K1 in sequence. During this process, the second opening K2 is in an open state, and the first opening K1 is in a closed state. Since the second opening K2 is in an open state, the positioning element 5 on workpiece 200 can easily enter the second opening K2 and be guided by the second opening K2 to the first opening K1. Since the first opening K1 is in a closed state, the positioning element 5 on workpiece 200 is confined within the narrow first opening K1. Thus, the movement direction of workpiece 200 is not deviated through the first opening K1, ensuring that workpiece 200 can be transferred to the designated position on the first device 1.

[0052] In related technologies, the processing system does not have a transition device. During the process of transferring the workpiece between the first device and the second device, the workpiece is prone to skewing, which may cause the workpiece to be unable to be transferred smoothly from the first device to the designated position of the second device, or vice versa, resulting in the workpiece being jammed or even damaged.

[0053] The transition device 3 provided in this application overcomes the problems in related technologies. The transition device 3 includes a first guide component 31 and a drive component 33. The first guide component 31 has a first opening K1 and a second opening K2 that are connected. The drive component 33 drives the first guide component 31 to change the size of the first opening K1 and the second opening K2. The first opening K1 and the second opening K2 have opposite trends in increasing and decreasing; that is, when the first opening K1 increases, the second opening K2 decreases, and when the first opening K1 decreases, the second opening K2 increases. It is understood that the increased first opening K1 (or second opening K2) facilitates the entry of the positioning element 5 on the workpiece 200 and guides the positioning element 5 into the decreased second opening K2 (or first opening K1). The decreased second opening K2 (or first opening K1) can limit the movement direction of the workpiece 200 to prevent deviation by the positioning element 5, thereby regulating the conveying movement of the workpiece 200 and ensuring that the workpiece 200 can be accurately and smoothly conveyed between the first device 1 and the second device 2.

[0054] It should be noted that the number of positioning elements 5 on workpiece 200 can be one or more (two or more). When the number of positioning elements 5 is three or more, all positioning elements 5 are arranged in a straight line.

[0055] Furthermore, the change in the size of the first opening K1 and the second opening K2 is achieved by the movement of at least one of the first sub-component 311 and the second sub-component 312. It should be noted that this application only illustrates the simultaneous movement of the first sub-component 311 and the second sub-component 312.

[0056] The first sub-component 311 and the second sub-component 312 are connected. The first sub-component 311 can transmit motion to the second sub-component 312, or the second sub-component 312 can transmit motion to the first sub-component 311, so that the size of the first opening K1 and the second opening K2 can be changed together by the first sub-component 311 and the second sub-component 312.

[0057] In other words, since the first sub-component 311 and the second sub-component 312 are connected, the movement of one will drive the other. That is, when the first sub-component 311 moves, the second sub-component 312 will follow the first sub-component 311, or when the second sub-component 312 moves, the first sub-component 311 will follow the second sub-component 312. Therefore, the drive component 33 only needs to drive either the first sub-component 311 or the second sub-component 312, without the need for two sets of drive components 33 to drive the first sub-component 311 and the second sub-component 312 separately, thereby saving costs and assembly space.

[0058] Please refer to Figure 9 The first sub-component 311 includes a first guide block 3111 and a first transmission member 3112 connected to each other. The second sub-component 312 includes a second guide block 3121 and a second transmission member 3122 connected to each other. The first guide block 3111 and the second guide block 3121 are spaced apart and together form the first opening K1 and the second opening K2. The first transmission member 3112 and the second transmission member 3122 are connected to each other to enable the first sub-component 311 and the second sub-component 312 to rotate synchronously.

[0059] Please refer to Figure 10 Specifically, the first guide block 3111 and the second guide block 3121 are approximately triangular in shape. The first guide block 3111 has a first sidewall M1 and a second sidewall M2 that are relatively inclined. The second guide block 3121 has a third sidewall M3 and a fourth sidewall M4 that are relatively inclined. The first sidewall M1 and the third sidewall M3 are arranged opposite to each other and together form a first opening K1. The second sidewall M2 and the fourth sidewall M4 are arranged opposite to each other and together form a second opening K2.

[0060] The first transmission component 3112 and the first guide block 3111 rotate synchronously. The second transmission component 3122 and the second guide block 3121 rotate synchronously. The first transmission component 3112 and the first guide block 3111 can be connected by a first rotating shaft 3113. The second transmission component 3122 and the second guide block 3121 can be connected by a second rotating shaft 3123. The first transmission component 3112 and the second transmission component 3122 can be gears, and the two mesh directly. Optionally, the first transmission component 3112 and the second transmission component 3122 can both be gears with the same dimensional parameters, that is, their module, number of teeth, and other parameters are equal.

[0061] When the first transmission member 3112 and the second transmission member 3122 rotate, they drive the first guide block 3111 and the second guide block 3121 to rotate synchronously, and the included angle between the first side wall M1 and the third side wall M3 increases or decreases accordingly, that is, the first opening K1 increases or decreases accordingly; at the same time, the included angle between the second side wall M2 and the fourth side wall M4 increases or decreases accordingly, that is, the second opening K2 increases or decreases accordingly.

[0062] Optionally, when the first sidewall M1 and the third sidewall M3 are parallel (i.e., the angle between the first sidewall M1 and the third sidewall M3 is zero), the first opening K1 is at its minimum. At this time, the angle between the second sidewall M2 and the fourth sidewall M4 is greater than zero, and the second opening K2 is at its maximum. When the second sidewall M2 and the fourth sidewall M4 are parallel (i.e., the angle between the second sidewall M2 and the fourth sidewall M4 is zero), the second opening K2 is at its minimum. At this time, the angle between the first sidewall M1 and the third sidewall M3 is greater than zero, and the first opening K1 is at its maximum.

[0063] Please refer to Figure 11 The transition device 3 further includes a second guide component 32, which includes a third sub-component 321 and a fourth sub-component 322. The third sub-component 321 and the fourth sub-component 322 together form a connected third opening K3 and a fourth opening K4. The third opening K3 faces the second opening K2, meaning the third opening K3 is closer to the second opening K2 than the fourth opening K4. The driving component 33 is also used to drive the second guide component 32 to change the size of the third opening K3 and the fourth opening K4. Specifically, the third opening K3 increases or decreases synchronously with the first opening K1, and the fourth opening K4 increases or decreases synchronously with the second opening K2.

[0064] Specifically, the first guide component 31 is adjacent to the first device 1, and the second guide component 32 is adjacent to the second device 2. Optionally, the arrangement direction of the first guide component 31 and the second guide component 32 is consistent with the arrangement direction of the first device 1 and the second device 2, and the arrangement direction of the third opening K3 and the fourth opening K4 is consistent with the arrangement direction of the first device 1 and the second device 2. In other embodiments, the arrangement direction of the first guide component 31 and the second guide component 32 may also be inclined to the arrangement direction of the first device 1 and the second device 2, that is, the workpiece 200 is conveyed at an angle.

[0065] The driving component 33 can drive the second guiding component 32, causing the size of the third opening K3 and the fourth opening K4 to change, and the two change in opposite trends, that is, when the third opening K3 increases, the fourth opening K4 decreases, and when the third opening K3 decreases, the fourth opening K4 increases.

[0066] The enlarged third opening K3 (or fourth opening K4) is in an open state, which facilitates the entry of the positioning element 5 on the workpiece 200. The reduced third opening K3 (or fourth opening K4) is in a limited state, which limits the position of the positioning element 5.

[0067] The third opening K3 changes synchronously with the first opening K1, and the fourth opening K4 changes synchronously with the second opening K2. In other words, when the first opening K1 is in an open (or limited) state, the third opening K3 is also in an open (or limited) state. When the second opening K2 is in an open (or limited) state, the fourth opening K4 is also in an open (or limited) state.

[0068] During the process of workpiece 200 being transferred from the first device 1 to the second device 2, both the first opening K1 and the third opening K3 are in an open state. During the process of workpiece 200 being transferred from the second device 2 to the first device 1, both the fourth opening K4 and the second opening K2 are in an open state.

[0069] The third sub-component 321 and the fourth sub-component 322 are connected. The third sub-component 321 can transmit motion to the fourth sub-component 322, or the fourth sub-component 322 can transmit motion to the third sub-component 321, so that the size of the third opening K3 and the fourth opening K4 can be changed together by the third sub-component 321 and the fourth sub-component 322.

[0070] In other words, since the third sub-component 321 and the fourth sub-component 322 are connected, the movement of one of them will drive the other. That is, when the third sub-component 321 moves, the fourth sub-component 322 will follow the movement of the third sub-component 321, or when the fourth sub-component 322 moves, the third sub-component 321 will follow the movement of the fourth sub-component 322. Therefore, the drive component 33 only needs to drive either the third sub-component 321 or the fourth sub-component 322, without the need for two sets of drive components 33 to drive the third sub-component 321 and the fourth sub-component 322 separately, thus saving costs and assembly space.

[0071] Please refer to Figure 11 The third sub-component 321 includes a third guide block 3211 and a third transmission member 3212 connected to each other. The fourth sub-component 322 includes a fourth guide block 3221 and a fourth transmission member 3222 connected to each other. The third guide block 3211 and the fourth guide block 3221 are spaced apart and together form the third opening K3 and the fourth opening K4. The third transmission member 3212 and the fourth transmission member 3222 are connected to each other so that the third sub-component 321 and the fourth sub-component 322 rotate synchronously.

[0072] Specifically, the third guide block 3211 and the fourth guide block 3221 are approximately triangular in shape. The third guide block 3211 has relatively inclined fifth sidewalls M5 and M6. The fourth guide block 3221 has relatively inclined seventh sidewalls M7 and M8. The fifth sidewalls M5 and M7 are arranged opposite to each other and together form the third opening K3. The sixth sidewalls M6 and M8 are arranged opposite to each other and together form the fourth opening K4.

[0073] The third transmission component 3212 and the third guide block 3211 rotate synchronously. The fourth transmission component 3222 and the fourth guide block 3221 rotate synchronously. The third transmission component 3212 and the third guide block 3211 can be connected via the third rotating shaft 3213. The fourth transmission component 3222 and the fourth guide block 3221 can be connected via the fourth rotating shaft 3223. The third transmission component 3212 and the fourth transmission component 3222 can be gears, and the two mesh directly. Optionally, the third transmission component 3212 and the fourth transmission component 3222 can both be gears with the same dimensional parameters, that is, their module, number of teeth, and other parameters are equal.

[0074] When the third transmission component 3212 and the fourth transmission component 3222 rotate, they drive the third guide block 3211 and the fourth guide block 3221 to rotate synchronously, respectively. The included angle between the fifth side wall M5 and the seventh side wall M7 increases or decreases accordingly, that is, the third opening K3 increases or decreases accordingly. At the same time, the included angle between the sixth side wall M6 and the eighth side wall M8 increases or decreases accordingly, that is, the fourth opening K4 increases or decreases accordingly.

[0075] Optionally, when the fifth sidewall M5 and the seventh sidewall M7 are parallel (i.e., the angle between the fifth sidewall M5 and the seventh sidewall M7 is zero), the third opening K3 is at its minimum. At this time, the angle between the sixth sidewall M6 and the eighth sidewall M8 is greater than zero, and the fourth opening K4 is at its maximum. When the sixth sidewall M6 and the eighth sidewall M8 are parallel (i.e., the angle between the sixth sidewall M6 and the eighth sidewall M8 is zero), the fourth opening K4 is at its minimum. At this time, the angle between the fifth sidewall M5 and the seventh sidewall M7 is greater than zero, and the third opening K3 is at its maximum.

[0076] Please refer to Figure 12 The transition device 3 further includes a connecting rod 34, which connects the first guide component 31 and the second guide component 32 to enable synchronous movement of the first guide component 31 and the second guide component 32. In other words, the connecting rod 34 can transmit the movement of the first guide component 31 to the second guide component 32, or vice versa. Therefore, the drive component 33 only needs to drive either the first guide component 31 or the second guide component 32.

[0077] In one embodiment, the connecting rod 34 can be connected to the second sub-assembly 312 and the fourth sub-assembly 322 respectively, and the second sub-assembly 312 and the fourth sub-assembly 322 are linked together by the connecting rod 34. Further, the connecting rod 34 can be connected to the second guide block 3121 and the fourth guide block 3221 respectively (e.g., Figure 12 (as shown), or connected to the second rotating shaft 3123 and the fourth rotating shaft 3223 respectively, or connected to the second transmission component 3122 and the fourth transmission component 3222 respectively.

[0078] In another embodiment, the connecting rod 34 can also be connected to the first sub-assembly 311 and the third sub-assembly 321 respectively, and the first sub-assembly 311 and the third sub-assembly 321 are linked together by the connecting rod 34. Further, the connecting rod 34 can be connected to the first guide block 3111 and the third guide block 3211 respectively, or to the first rotating shaft 3113 and the third rotating shaft 3213 respectively, or to the first transmission member 3112 and the third transmission member 3212 respectively.

[0079] The number of driving components 33 can be one. The driving component 33 can drive only one of the four sub-components 311, 312, 321, and 322, thereby achieving synchronous rotation of the four components.

[0080] The fourth sub-component 322 is driven by the drive component 33, and the connecting rod 34 is connected to the second sub-component 312 and the fourth sub-component 322 for illustrative purposes: When the drive component 33 is working, it drives the fourth sub-component 322 to rotate; the fourth sub-component 322 drives the third transmission component 3212 to rotate through the fourth transmission component 3222, thereby causing the third sub-component 321 to rotate; the fourth sub-component 322 drives the second sub-component 312 to rotate through the connecting rod 34; the second sub-component 312 then drives the first transmission component 3112 to rotate through the second transmission, thereby causing the first sub-component 311 to rotate.

[0081] Please refer to Figure 13 The transition device 3 further includes a seat assembly 35 for supporting the workpiece 200. The seat assembly 35 has a guide channel D, which is straight. One end of the guide channel D is connected to the second opening K2 of the first guide assembly 31. The other end of the guide channel D is connected to the third opening K3 of the second guide assembly 32. The guide channel D is used to define the movement path of the workpiece 200 by means of the positioning element 5.

[0082] Specifically, the first guide component 31 guides the positioning element 5 of the workpiece 200 to sequentially pass through the first opening K1 (open state) and the second opening K2 (limited state) into the guide channel D, and then sequentially pass through the third opening K3 (open state) and the fourth opening K4 (limited state) from the guide channel D. The second guide component 32 guides the positioning element 5 of the workpiece 200 to sequentially pass through the fourth opening K4 (open state) and the third opening K3 (limited state) into the guide channel D, and then sequentially pass through the second opening K2 (open state) and the first opening K1 (limited state) from the guide channel D.

[0083] Optionally, when the second opening K2 is in the limiting state, the width of the second opening K2 is less than or equal to the width of the guide channel D, thereby ensuring that the positioning member 5 can smoothly enter the guide channel D from the second opening K2.

[0084] Optionally, when the third opening K3 is in the limiting state, the width of the third opening K3 is less than or equal to the width of the guide channel D, thereby ensuring that the positioning member 5 can smoothly enter the guide channel D through the third opening K3.

[0085] Please refer to Figure 14The seat assembly 35 includes a base 353, a first cover plate 351, and a second cover plate 352. The base 353 includes a bottom plate portion 3533, a first side plate portion 3531, and a second side plate portion 3532. The first side plate portion 3531 and the second side plate portion 3532 are arranged opposite to each other and are respectively bent and connected to opposite ends of the bottom plate portion 3533. The first cover plate 351 includes a bent and connected first top plate portion 3511 and a first limiting portion 3512. The second cover plate 352 includes a bent and connected second top plate portion 3521 and a second limiting portion 3522. The end of the first top plate portion 3511 away from the first limiting portion 3512 is connected to the first side plate portion 3531, and the end of the first limiting portion 3512 away from the first top plate portion 3511 is connected to the bottom plate portion 3533. The end of the second top plate portion 3521 away from the second limiting portion 3522 is connected to the second side plate portion 3532, and the end of the second limiting portion 3522 away from the second top plate portion 3521 is connected to the bottom plate portion 3533. The first limiting portion 3512 and the second limiting portion 3522 are arranged opposite to each other and at intervals to jointly form the guide channel D.

[0086] Please refer to Figure 13 The seat assembly 35 further includes a plurality of rollers 354, which are rotatably connected to the base 353 and arranged circumferentially along the base 353. In the direction from the base plate portion 3533 to the first top plate portion 3511 and the second top plate portion 3521, the rollers 354 protrude from the first top plate portion 3511 and the second top plate portion 3521. It is understood that the plate body 4 of the workpiece 200 has a certain volume. When the workpiece 200 moves at least partially to the transition device 3, the plate body 4 can be supported by the rollers 354, thereby allowing the workpiece 200 to move smoothly and travel along the extension direction of the guide channel D. Simultaneously, the rollers 354 are rotatable, thereby reducing wear during the movement of the workpiece 200.

[0087] Please refer to Figure 15 The transition device 3 further includes a blocking assembly 36, which includes a driving member 362 and a blocking member 361 connected to each other. The driving member 362 drives the blocking member 361 to move so that the blocking member 361 is located in the extending direction from the first opening K1 to the second opening K2. The blocking member 361 is used to obstruct the positioning member 5 on the workpiece 200.

[0088] Specifically, the blocking member 361 has a blocking state (see reference). Figure 16 and Figure 17 ) and release status (refer to Figure 18The driving component 362 can drive the blocking component 361 to switch between a blocking state and a releasing state. When the blocking component 361 is in the blocking state, it is located in the extension direction from the first opening K1 to the second opening K2, that is, it is located on the movement path of the positioning component 5. When the positioning component 5 comes into contact with the blocking component 361, the workpiece 200 stops moving. The position where the workpiece 200 stops is a preset position, which facilitates the second device 2 to pick up the workpiece 200. Therefore, the blocking component 361 serves to position the workpiece 200 in the preset position. When the blocking component 361 is in the releasing state, it is not in the extension direction from the first opening K1 to the second opening K2, and therefore does not block the movement of the positioning component 5.

[0089] Optionally, the movement direction of the blocking member 361 is parallel to the direction from the first top plate portion 3511 and the second top plate portion 3521 towards the bottom plate portion 3533. The orthographic projection of the blocking member 361 onto the first top plate portion 3511 and the second top plate portion 3521 at least partially falls within the area between the first top plate portion 3511 and the second top plate portion 3521; in other words, the blocking member 361 is directly opposite the guide channel D. When the positioning member 5 is located in the guide channel D, the height of the positioning member 5 from the bottom plate portion 3533 is a first height; the height of the blocking member 361 protruding from the bottom plate portion 3533 is a second height. When the blocking member 361 is in a blocking state, the second height is greater than or equal to the first height, and the positioning member 5 is blocked; when the blocking member 361 is in a releasing state, the second height is less than the first height, and the positioning member 5 is not blocked.

[0090] Please refer to Figure 16 Optionally, the blocking member 361 is further provided with a limiting groove C1. The limiting groove C1 is located on the side of the blocking member 361 near the first guide assembly 31 and is used to accommodate at least a portion of the positioning members 5 on the workpiece 200. Since the width of the guide channel D is greater than that of the positioning members 5, the stopping positions of the positioning members 5 on different workpieces 200 will be different. With the limiting groove C1, the positioning members 5 on different workpieces 200 will all move into the limiting groove C1, thereby improving the stopping accuracy of the workpiece 200 and the accuracy of the second device 2 in picking up the workpiece 200 will also be higher.

[0091] Please refer to Figure 15The blocking assembly 36 further includes an adjusting member 363 with a through hole C2, which is directly or indirectly supported by the base 353. The through hole C2 penetrates the adjusting member 363, and the penetration direction is parallel to the direction from the first top plate portion 3511 and the second top plate portion 3521 to the bottom plate portion 3533. The blocking member 361 is inserted into the through hole C2 and can move within the through hole C2 along the penetration direction of the through hole C2, thereby enabling the blocking member 361 to switch between a blocking state and a releasing state.

[0092] Please refer to Figure 15 The blocking assembly 36 further includes a connecting member 364. One end of the connecting member 364 is fixed to the adjusting member 363, and the end of the connecting member 364 away from the first top plate portion 3511 and the second top plate portion 3521 is connected to the driving member 362 to fix the driving member 362 on the adjusting member 363. The driving member 362 is disposed opposite to and connected to the blocking member 361. The driving member 362 is used to drive the blocking member 361 to move linearly along the through-hole C2. The driving member 362 may be, but is not limited to, a cylinder. The cylinder has a piston rod and a cylinder body. The cylinder body is supported by the connecting member 364. The piston rod can move linearly within the cylinder body, and the direction of movement of the piston rod is parallel to the through-hole C2. The piston rod is connected to and used to drive the blocking member 361 to switch the blocking member 361 between a blocking state and a releasing state.

[0093] Please refer to Figure 19 The drive assembly 33 is fixed to the base 353. The drive assembly 33 includes a power component 331 and a fifth transmission component 332 connected to each other. The power component 331 is used to drive the fifth transmission component 332. The fifth transmission component 332 is used to connect and drive any one of the four sub-assemblies 311, 312, 321, and 322 to rotate, thereby realizing the simultaneous rotation of the four components.

[0094] Optionally, the fifth transmission component 332 connects to and drives any one of the first transmission component 3112, the second transmission component 3122, the third transmission component 3212, and the fourth transmission component 3222.

The power component 331 drives the rack to move linearly, and the rack then drives the gear to rotate.

[0096] Optionally, the power component 331 is a cylinder, which includes a cylinder body and a piston rod disposed within the cylinder body. The piston rod is connected to the fifth transmission component 332 and is used to drive the fifth transmission component 332 to move linearly.

[0097] Please refer to Figure 13 The seat assembly 35 further includes a first support block 355, which is supported on the base 353. The first sub-assembly 311 and the second sub-assembly 312 are supported on the first support block 355. A first rotating shaft 3113 of the first sub-assembly 311 passes through the first support block 355 and the base plate 3533, and the first rotating shaft 3113 is rotatably connected to the first support block 355 via a bearing. A second rotating shaft 3123 of the second sub-assembly 312 passes through the first support block 355 and the base plate 3533, and the second rotating shaft 3123 is rotatably connected to the first support block 355 via a bearing. A first guide block 3111 and a second guide block 3121 are located on the side of the first support block 355 opposite to the base plate 3533. A first transmission member 3112 and a second transmission member 3122 are located on the side of the base plate 3533 opposite to the first support block 355. The first guide block 3111, the first transmission component 3112, the second guide block 3121, and the second transmission component 3122 are all spaced apart from the first bearing block 355 to avoid friction.

[0098] Please refer to Figure 13 The seat assembly 35 further includes a second support block 356, which is supported on the base 353. The third sub-assembly 321 and the fourth sub-assembly 322 are supported on the second support block 356. A third rotating shaft 3213 of the third sub-assembly 321 passes through the second support block 356 and the base plate 3533, and is rotatably connected to the second support block 356 via a bearing. A fourth rotating shaft 3223 of the fourth sub-assembly 322 passes through the second support block 356 and the base plate 3533, and is rotatably connected to the second support block 356 via a bearing. A third guide block 3211 and a fourth guide block 3221 are located on the side of the second support block 356 opposite to the base plate 3533. A third transmission member 3212 and a fourth transmission member 3222 are located on the side of the base plate 3533 opposite to the second support block 356. The third guide block 3211, the third transmission component 3212, the fourth guide block 3221, and the fourth transmission component 3222 are all spaced apart from the second bearing block 356 to avoid friction.

[0099] Please refer to Figure 12 and Figure 13The transition device 3 further includes a guide rod 357, which is a straight rod. The opposite ends of the guide rod 357 are connected to the first bearing block 355 and the second bearing block 356, respectively, and pass through the blocking assembly 36. The extending direction of the guide rod 357 is parallel to the extending direction of the guide channel D. The blocking assembly 36 can slide along the extending direction of the guide rod 357. It is understood that the stopping position of the workpiece 200 will also change with the position of the blocking assembly 36; that is, the position of the blocking assembly 36 is adjustable, allowing the workpiece 200 to stop at multiple positions accordingly. It is understood that the position of the positioning member 5 relative to the plate 4 may differ for different batches of workpieces 200. If the position of the blocking assembly 36 is not adjusted, the position of the plate 4 relative to the second device 2 will change, which is detrimental to the second device 2 picking up the workpiece 200. In this embodiment, the position of the blocking assembly 36 is adjustable, thereby allowing for a position that is advantageous for the second device 2 to pick up the workpiece 200.

[0100] Optionally, there may be multiple guide rods 357, which are arranged in parallel. It is understood that setting multiple guide rods 357 is beneficial to the smooth sliding of the blocking assembly 36.
