Description

Technical Field

[0001] This invention relates to the field of circuit board processing equipment technology, and in particular to a workstation for a printed circuit board production line. Background Technology

[0002] Printed circuit board (PCB) manufacturing processes typically include substrate preparation, mechanical drilling, plasma desmearing and activation, frame insertion, chemical copper plating through-hole (PTH) vias, full-board electroplating, and dry film pattern transfer. PCB production lines connect multiple processing equipment in series, improving the convenience of PCB production and reducing production costs. However, the efficiency of processing equipment varies across different processes. To maintain production continuity, the production speed of some equipment is forced to be reduced to accommodate less efficient equipment. For example, before chemical copper plating through-holes, a frame insertion device is needed to insert the substrate into a bracket (frame). The low efficiency of the frame insertion device and unexpected shutdowns of subsequent processing equipment will reduce the efficiency or even halt the preceding processing equipment, affecting the utilization rate of the preceding processing equipment and the overall PCB production efficiency. Furthermore, there may be situations where additional auxiliary materials are needed or the substrate needs to be transferred to other production lines. This necessitates adding feeding equipment next to the equipment requiring additional auxiliary materials and unloading equipment next to the corresponding processing equipment, increasing the space occupied by the entire production line, making the structure more complex and difficult to maintain. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a workstation for a printed circuit board production line that coordinates the production of upstream and downstream processing equipment.

[0004] According to an embodiment of the present invention, a printed circuit board production line workstation is disposed between upstream processing equipment and downstream processing equipment. It includes a frame with a first workstation, a conveying device, and a second workstation arranged sequentially from right to left. A loading station is located in front of the second workstation on the frame. The first workstation is used to store substrates, and the conveying device is used to transport substrates to the downstream processing equipment. A second pallet and a transfer cart are also included. The transfer cart is movable to the second workstation. A first lifting drive mechanism is provided at the second workstation. The output end of the first lifting drive mechanism is connected to a bracket, which is used to lift the second pallet to place it on the transfer cart or to transfer the second pallet to the downstream processing equipment. The second pallet on the transport vehicle is lifted; the loading mechanism includes a third pallet for carrying the plating workpiece or the substrate, the third pallet being capable of reciprocating between the loading station and the second station; a first transport device is configured to transport the substrate on the preceding processing equipment to any one of the first station, the conveying device, the second pallet at the second station, or the third pallet; a second transport device is configured to transport the substrate at the first station, the substrate on the second pallet at the second station, or the substrate or the plating workpiece on the third pallet at the second station to the conveying device.

[0005] It has at least the following beneficial effects: The first transport device moves the substrates from the preceding processing equipment to the second / third tray at the first or second workstation, temporarily storing the substrates processed by the preceding equipment. The second transport device moves the substrates from the second / third tray at the first or second workstation to the conveyor device, delivering the substrates to subsequent processing equipment. The transfer cart also unloads the substrates. The workstation on the printed circuit board production line serves to temporarily store some substrates, unload substrates, and deliver substrates to subsequent processing equipment. It adapts to the production efficiency of both preceding and subsequent processing equipment, preventing efficiency reduction or even shutdown of the preceding equipment, and improving the utilization rate of the preceding equipment and the production efficiency of the circuit boards. The workstation also enables the feeding of plating components to subsequent processing equipment via a loading mechanism. The printed circuit board production line workstation can store substrates, deliver substrates to subsequent processing equipment on demand, unload / load substrates and load plating parts, and coordinate the production of upstream and downstream processing equipment. The layout of the first station, conveying device, second station and loading station, as well as the setting of loading mechanism, first handling device and second handling device, make the workstation structure more compact, occupy less space and are easier to maintain.

[0006] According to some embodiments of the present invention, the third tray includes a tray plate and a limiting plate. The tray plate is provided with limiting blocks on its rear side and left and right sides. The limiting plate is located on the front side of the tray plate and can move in the front-back direction. The tray plate is used to support the lower surface of the plating component or the substrate. The limiting plate and the three limiting blocks are respectively used to abut against the four end faces of the plating component or the substrate.

[0007] According to some embodiments of the present invention, a first tray is further included, which is disposed at the first workstation and is used to carry the substrate. The structure of the first tray is the same as that of the third tray.

[0008] According to some embodiments of the present invention, the feeding mechanism further includes a first linear drive mechanism connected to the frame, the output end of the first linear drive mechanism being connected to the third tray, and the first linear drive mechanism being used to drive the third tray to move in a front-back direction so that the third tray can reciprocate between the feeding station and the second station.

[0009] According to some embodiments of the present invention, the first handling device includes a robot arm and a second suction device. The robot arm is connected to the frame, and the end of the robot arm is connected to the second suction device. The second suction device is used to pick up the substrate. The robot arm drives the second suction device to move between the pre-processing equipment and the first station, the conveying device and the second station, so that the second suction device transports the substrate on the pre-processing equipment to any one of the first station, the conveying device or the second station.

[0010] According to some embodiments of the present invention, the second suction device includes an adapter frame, a drive device, two sets of suction cup assemblies, two sets of clamping plate assemblies, and a first sliding member and a first guide rail that cooperate with each other. The adapter frame is connected to the end of the robot arm. The two sets of suction cup assemblies are distributed on the left and right sides of the adapter frame. The suction cup assemblies are used to adsorb the substrate on the support surface of the output station of the preceding processing equipment. The clamping plate assembly includes an upper clamping plate and a lower clamping plate. The lower clamping plate can rotate about a horizontal axis to move closer to or away from the upper clamping plate to clamp or release the substrate in a clamping position in the vertical direction. The first guide rail is connected to the adapter frame. The clamping plate assembly is connected to the first sliding member. The clamping plate assembly can slide on the first guide rail to be in a position of avoidance away from the clamping position of the substrate, or in a position close to the substrate. The clamping position of the plate is determined by a driving device including a third lifting drive mechanism, a second guide rail, and a second sliding member that cooperate with each other. The length direction of the second guide rail extends horizontally, and the second sliding member is connected to the first sliding member. The third lifting drive mechanism is connected to the adapter frame, and the output end of the third lifting drive mechanism is connected to the second guide rail. When the third lifting drive mechanism drives the second guide rail to rise, the clamping plate assembly is in the avoidance position, and the lower clamping plate is away from the upper clamping plate. After the suction cup assembly picks up the substrate from the support surface, the third lifting drive mechanism drives the second guide rail to descend, and the clamping plate assembly moves to the clamping position. The upper clamping plate abuts against the upper surface of the clamping position, and the lower clamping plate is close to the upper clamping plate and abuts against the lower surface of the clamping position.

[0011] According to some embodiments of the present invention, the first guide rail includes a vertical section and a curved section, the upper end of the vertical section is connected to the lower end of the curved section, the upper end of the curved section is curved upward between the two sets of suction cup assemblies, and the first sliding member is capable of sliding on the vertical section and the curved section to switch the clamping plate assembly between the clamping position and the avoidance position.

[0012] According to some embodiments of the present invention, a vertical plate is connected to the adapter frame, the first guide rail is a groove formed on the vertical plate, and the first sliding member extends into the groove.

[0013] According to some embodiments of the present invention, the second suction device further includes a sliding frame, the clamping plate assembly is connected to the sliding frame, the sliding frame is connected to the first sliding member, the first sliding member is rotatably connected to a rotating wheel, the rotating wheel is accommodated in the groove, the rotating wheel abuts against the inner wall of the groove, and the depth direction of the groove and the axial direction of the rotating wheel are parallel to each other.

[0014] According to some embodiments of the present invention, two sets of clamping plate assemblies are distributed left and right, the planes in which the vertical section and the curved section are located are perpendicular to the front-back direction, and the length direction of the second guide rail extends along the left-right direction.

[0015] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] Reference Figures 1 to 4 This invention discloses a workstation for a printed circuit board (PCB) production line. The workstation is positioned between pre-processing equipment (such as ion desizing and activation equipment) and post-processing equipment (such as frame insertion equipment). (Refer to...) Figure 1 or Figure 2The printed circuit board production line workstation includes a frame 100, a second pallet 400, a transfer cart 500, a loading mechanism 600, a first handling device 200, and a second handling device 300. The frame 100 has a first workstation 110, a conveying device 120, and a second workstation 130 arranged sequentially from right to left. A loading workstation 140 is located in front of the second workstation 130. The first workstation 110 is used to store substrates 10, and the conveying device 120 is used to transport substrates 10 to subsequent processing equipment. The transfer cart 500 can move to the second workstation 130. A first lifting drive mechanism is located at the second workstation 130. The output end of the first lifting drive mechanism is connected to a bracket, which is used to lift the second pallet 400 to place the second pallet 400 onto the transfer cart 500 or to transfer it to the second workstation 500. The second pallet 400 on the transport vehicle 500 is lifted; the loading mechanism 600 includes a third pallet 610, which is used to carry the plating part 20 or the substrate 10, and the third pallet 610 can reciprocate between the loading station 140 and the second station 130; the first transport device 200 is configured to transport the substrate 10 on the preceding processing equipment to any one of the first station 110, the conveying device 120, the second pallet 400 or the third pallet 610 at the second station 130; the second transport device 300 is configured to transport the substrate 10 on the first station 110, the substrate 10 on the second pallet 400 at the second station 130, or the substrate 10 or the plating part 20 on the third pallet 610 at the second station 130 to the conveying device 120.

[0021] When the subsequent processing equipment stops, the first transport device 200 transports the substrate 10 from the preceding processing equipment to the second tray 400 at the first station 110 or the third tray 610 at the second station 130, thus temporarily storing the substrate 10 processed by the preceding processing equipment. When the subsequent processing equipment is inefficient and cannot complete the substrate 10 processed by the preceding processing equipment in time, the first transport device 200 transports the substrate 10 from the preceding processing equipment to one of the following in sequence: the transport device 120, the first station 110, and the second tray 400 or the third tray 610 at the second station 130. Both the first station 110 and the second station 130 can temporarily store the substrate 10. The transport device 120 transports the substrate 10 to the subsequent processing equipment, thus simultaneously transporting the substrate 10 to the subsequent processing equipment and temporarily storing the substrate 10 that the subsequent processing equipment cannot process in time.

[0022] The workstation of the printed circuit board production line serves to temporarily store some of the substrates 10 and to feed the substrates 10 to subsequent processing equipment, thereby avoiding the reduction in efficiency or even shutdown of the preceding processing equipment and improving the utilization rate of the preceding processing equipment and the production efficiency of the circuit boards.

[0023] When the preceding processing equipment stops outputting substrate 10 or the speed at which the output substrate 10 is not fast enough to reach the speed at which the subsequent processing equipment processes substrate 10, the second transport device 300 transports the substrate 10 from the second tray 400 at the first station 110 and the second station 130 / the third tray 610 at the second station 130 to the transport device 120, thereby completing the delivery of the stored substrate 10 to the transport device 120 and enabling the stored substrate 10 to be put into the subsequent processing equipment for subsequent processing.

[0024] Of course, the working mode of a printed circuit board production line workstation can also be as follows: The first transport device 200 does not directly transport the substrate 10 to the conveying device 120. Instead, the first transport device 200 transports the substrate 10 from the preceding processing equipment to the first station 110, where the first station 110 stores the substrate 10. At this time, the second transport device 300 transports the substrate 10 stored at the second station 130 to the conveying device 120, thus completing the delivery of the substrate 10 stored at the second station 130 to the conveying device 120, achieving simultaneous storage and delivery of materials.

[0025] When the number of substrates 10 stored in the first station 110 reaches a preset value or there are no substrates 10 on the second station 130, the first conveying device 200 changes to conveying the substrates 10 of the preceding processing equipment to the second station 130. The second station 130 stores the substrates 10, and the second conveying device 300 changes to conveying the substrates 10 stored in the first station 110 to the conveying device 120, thus completing the delivery of the substrates 10 stored in the first station 110 to the conveying device 120. This also enables simultaneous storage and delivery of materials, and so on to achieve continuous operation.

[0026] The first transport device 200 receives the substrate 10 from the preceding processing equipment and stores it. The working cycle of the first transport device 200 is matched with that of the preceding processing equipment. The second transport device 300 only delivers the stored substrate 10 to the conveyor device 120, which then transports the substrate 10 to the subsequent processing equipment. The working cycle of the second transport device 300 is matched with that of the subsequent processing equipment. This working method makes it easier to control the first transport device 200 and the second transport device 300, avoids interference between them, and allows the workstation to easily adapt to the production efficiency of the two processing equipment, thus ensuring the production efficiency of the printed circuit board production line.

[0027] The bracket is used to support the second tray 400. When the bracket supports the second tray 400, the first transport device 200 transports the substrate 10 on the preceding processing equipment to the second tray 400 at the second station 130, or the second transport device 300 transports the substrate 10 on the second tray 400 at the second station 130 to the conveying device 120.

[0028] When the first lifting drive mechanism drives the bracket and the second workstation 130 on the bracket to a higher position, the first transport device 200 transports the substrate 10 from the preceding processing equipment to the second pallet 400 at the higher position. When the first lifting drive mechanism drives the bracket to a lower position, the second pallet 400 on the bracket can fall onto the transfer cart 500, placing the second pallet 400 on the transfer cart 500. The transfer cart 500 can transport the second pallet 400 to other temporary storage equipment or the second workstation 130 of other printed circuit board production line workstations to complete the unloading and storage of the substrate 10, and then transport the substrate 10 to other printed circuit board production line workstations for further processing. When the bracket descends to a lower position, the transfer cart 500 can carry the second pallet 400 to the second workstation 130, and then the first lifting drive mechanism drives the bracket to rise, allowing the bracket to lift the second pallet 400 on the transfer cart 500.

[0029] The arrangement of the first lifting drive mechanism, the bracket, the second pallet 400, and the transfer vehicle 500 enables the printed circuit board production line workstation to complete the unloading and storage of the substrate 10, or to transport the substrate 10 to other printed circuit board production line workstations.

[0030] The bracket includes multiple parallel support arms, all of which are connected to the output end of the first lifting drive mechanism. The transfer vehicle 500 is equipped with a support frame, which has multiple clearance slots. The support frame is used to support the second pallet 400. The multiple support arms can extend into the multiple clearance slots respectively, so that the multiple support arms can place the second pallet 400 on the support frame or lift the second pallet 400 on the support frame.

[0031] Initially, the first lifting drive mechanism drives multiple support arms to a higher position, lifting the second pallet 400 to the second station 130, so that the first transport device 200 can transport the substrate 10 from the preceding processing equipment to the second pallet 400 at the second station 130. When the substrate 10 needs to be unloaded, the transfer cart 500 moves to the second station 130, and the first lifting drive mechanism drives multiple support arms to descend to the corresponding clearance slots, so that the multiple support arms extend into the multiple clearance slots respectively, thereby causing the second pallet 400 on the multiple support arms to fall onto the support frame. When the substrate 10 needs to be transported to the second station 130, the first lifting drive mechanism drives multiple support arms to descend to the corresponding clearance slots, and the transfer cart 500 can move to the second station 130 so that the multiple support arms extend into the multiple clearance slots respectively. Then, the first lifting drive mechanism drives multiple support arms to rise, so that the multiple support arms can lift the second pallet 400 on the support frame.

[0032] It is conceivable that both the length of the support arm and the length of the clearance groove extend in the left-right direction, with the opening of the clearance groove facing upwards and its right end connecting to the space on the right side of the support frame. The transfer vehicle 500 moves in the left-right direction to move to or away from the second workstation 130. When the height of the support arm and the clearance groove are equal and they are directly opposite each other in the left-right direction, the transfer vehicle 500 moves from left to right, and the support arm can then extend into the clearance groove from its right end.

[0033] The third tray 610 can reciprocate between the loading station 140 and the second station 130, so that the first conveying device 200 can move the substrate 10 of the preceding processing equipment to the third tray 610 at the second station 130, and the second conveying device 300 can move the substrate 10 on the third tray 610 at the second station 130 to the conveying device 120; or the second conveying device 300 can move the plating part 20 on the third tray 610 at the second station 130 to the conveying device 120, and the plating part 20 can be conveyed to the frame insertion device through the conveying device 120. The frame insertion device inserts the plating part 20 into the bracket, and the bracket moves to the chemical copper plating through-hole equipment, and the chemical copper plating through-hole equipment can then perform corresponding processing on the substrate 10 and the plating part 20 on the bracket.

[0034] When the feeding mechanism 600 is used to feed the plating part 20, initially, the third tray 610 is at the feeding station 140. At this time, the plating part 20 can be loaded onto the third tray 610 at the feeding station 140. When it is necessary to transport the plating part 20 to the subsequent processing equipment, the first lifting drive mechanism drives the bracket to move down. The bracket carries the second tray 400 down, so that the second station 130 has clearance space. The third tray 610 can then be moved to the second station 130. At this time, the second conveying device 300 can transport the plating part 20 on the third tray 610 at the second station 130 to the conveying device 120.

[0035] When it is not necessary to feed the plating part 20 to the subsequent processing equipment, that is, when the feeding mechanism 600 is used to store the substrate 10, the first lifting drive mechanism drives the bracket to move down, and the bracket carries the second tray 400 down, so that the second station 130 has clearance space, and the third tray 610 can be moved to the second station 130. At this time, the first conveying device 200 can move the substrate 10 of the previous processing equipment to the third tray 610 at the second station 130, and the second conveying device 300 can move the substrate 10 on the third tray 610 at the second station 130 to the conveying device 120.

[0036] The printed circuit board production line workstation can realize the storage of substrate 10, the on-demand delivery of substrate 10 to subsequent processing equipment, the unloading of substrate 10 / loading of substrate 10 and the loading of plating parts 20, and the coordination of production of front and rear processing equipment. The layout of the first station 110, the conveying device 120, the second station 130 and the loading station 140, as well as the setting of the loading mechanism 600, the first handling device 200 and the second handling device 300, are more compact in structure, occupy less space and are easier to maintain than the current solution of adding loading / unloading equipment at the corresponding positions of each processing equipment.

[0037] Reference Figure 3 In some embodiments, the third tray 610 includes a tray 611 and a limiting plate 612. The tray 611 is provided with limiting blocks 611a on its rear side and left and right sides. The limiting plate 612 is provided on the front side of the tray 611 and can move in the front-back direction. The tray 611 is used to support the lower surface of the plating part 20 or the substrate 10, and plays the role of supporting the plating part 20 or the substrate 10. The three limiting blocks 611a can abut against the rear end face, left end face and right end face of the plating part 20 or the substrate 10, and the limiting plate 612 can abut against the front end face of the plating part 20 or the substrate 10, thus completing the support and limiting of the plating part 20 or the substrate 10.

[0038] When the limiting plate 612 moves forward, the distance between the limiting plate 612 and the rear limiting block 611a increases, while when the limiting plate 612 moves backward, the distance between the limiting plate 612 and the rear limiting block 611a decreases. The movement of the limiting plate 612 allows the third tray 610 to be used for plating parts 20 or substrates 10 of different sizes.

[0039] Reference Figure 3 The tray 611 is provided with a scale, which is used to measure the distance between the limiting plate 612 and the rear limiting block 611a. The scale indicates that the third tray 610 is suitable for supporting the plating part 20 or the substrate 10 in the front-back direction.

[0040] The feeding mechanism 600 also includes a first linear drive mechanism 620 connected to the frame 100. The output end of the first linear drive mechanism 620 is connected to the third tray 610. The first linear drive mechanism 620 is used to drive the third tray 610 to move in the front-back direction, so that the third tray 610 can reciprocate between the feeding station 140 and the second station 130.

[0041] The printed circuit board production line workstation also includes a first tray, which is located at the first station 110 and is used to carry the substrate 10. The structure and usage of the first tray are the same as or similar to those of the third tray 610, and will not be described redundantly here.

[0042] Reference Figure 2 and Figure 4 The second conveying device 300 includes a second linear drive mechanism 310, a second lifting drive mechanism 320, and a first suction device 330. The second linear drive mechanism 310 is connected to the frame 100. The output end of the second linear drive mechanism 310 is connected to the second lifting drive mechanism 320. The output end of the second lifting drive mechanism 320 is connected to the first suction device 330. The second linear drive mechanism 310 drives the second lifting drive mechanism 320 and the first suction device 330 to move in the left and right direction, so that the second lifting drive mechanism 320 and the first suction device 330 move above the first station 110, the conveying device 120, and the second station 130. The second lifting drive mechanism 320 drives the first suction device 330 to lift and lower. The first suction device 330 is used to suction the substrate 10.

[0043] Reference Figure 1 or Figure 2 In some embodiments, the first handling device 200 includes a robot arm 210 and a second suction device 220. The robot arm 210 is connected to the frame 100, and the end of the robot arm 210 is connected to the second suction device 220. The second suction device 220 is used to pick up the substrate 10. The robot arm 210 drives the second suction device 220 to move between the pre-processing equipment and the first station 110, the conveying device 120 and the second station 130, so that the second suction device 220 transports the substrate 10 on the pre-processing equipment to any one of the first station 110, the conveying device 120 or the second station 130.

[0044] It is conceivable that the preceding processing equipment has an output station, and the second pick-up device 220 can pick up the substrate 10 from the output station of the preceding processing equipment. The output station of the preceding processing equipment, the first tray, the second tray 400 and the third tray 610 all have a support surface and a side wall. The support surface is horizontal, and the side wall limits the substrate 10 in the horizontal direction. The conveying device 120 also has a support surface (also called a conveying surface).

[0045] Reference Figures 5 to 8The second suction device 220 includes an adapter frame 221 and two sets of suction cup assemblies 223. The adapter frame 221 is connected to the end of the robot arm 210. The two sets of suction cup assemblies 223 are distributed on the left and right sides of the adapter frame 221. The suction cup assemblies 223 are used to adsorb the substrate 10 on the support surface of the output station of the preceding processing equipment. The robot arm 210 drives the two sets of suction cup assemblies 223 to move through the adapter frame 221, so that the two sets of suction cup assemblies 223 can move to the support surface of the output station of the preceding processing equipment, thereby enabling the suction cup assemblies 223 to adsorb the substrate 10 from the support surface, or enabling the two sets of suction cup assemblies 223 to move to any one of the first station 110, the conveying device 120 or the second station 130, thereby enabling the suction cup assemblies 223 to place the substrate 10 on the support surface of the first tray, the second tray 400, the third tray 610 and the conveying device 120.

[0046] In some of these embodiments, reference is made to Figure 5 or Figure 8 The adapter frame 221 includes a horizontal plate 221a and two vertical rods 221b distributed to the left and right. A quick connector is connected to the middle of the horizontal plate 221a, and the horizontal plate 221a is connected to the end of the robot arm 210 through the quick connector. The two vertical rods 221b are both connected to the horizontal plate 221a and the spacing between them can be adjusted. Two sets of suction cup assemblies 223 are respectively provided on the two vertical rods 221b. The two sets of suction cup assemblies 223 are used to adsorb the left and right ends of the substrate 10. The spacing between the two sets of suction cup assemblies 223 is adjustable, so that the two sets of suction cup assemblies 223 are suitable for adsorbing substrates 10 of different sizes.

[0047] A third linear drive mechanism and a sliding mechanism are connected to the horizontal plate 221a. One vertical rod 221b is fixedly connected to one end of the horizontal plate 221a, and another vertical rod 221b is connected to the horizontal plate 221a via the sliding mechanism. The output end of the third linear drive mechanism is connected to the other vertical rod 221b. The third linear drive mechanism drives the other vertical rod 221b to move on the horizontal plate 221a, thereby adjusting the distance between the two vertical rods 221b. The two vertical rods 221b are parallel to each other and perpendicular to the horizontal plate 221a. Specifically, the length of the horizontal plate 221a extends in the left-right direction, and the two vertical rods 221b are distributed left and right. The sliding mechanism includes a sliding rail and a slider that cooperate with each other, and the sliding rail and the slider are respectively connected to the horizontal plate 221a and the other vertical rod 221b.

[0048] In another embodiment, two third linear drive mechanisms and two sliding mechanisms are connected to the horizontal plate 221a. Two vertical rods 221b are connected to the horizontal plate 221a through the two sliding mechanisms. The two third linear drive mechanisms are connected to the two vertical rods 221b respectively. The third linear drive mechanisms drive the vertical rods 221b to slide on the horizontal plate 221a, so that the two horizontal plates 221a move closer or further apart from each other with the middle of the horizontal plate 221a as the center.

[0049] Furthermore, the two third linear drive mechanisms can be a single bidirectional lead screw with opposite helical directions at both ends. The middle of the bidirectional lead screw is directly opposite the middle of the horizontal plate 221a, which corresponds to the area connecting the horizontal plate 221a and the robot arm 210. Both ends of the bidirectional lead screw are provided with lead screw nuts, which are connected to two vertical rods 221b respectively. Driving the bidirectional lead screw to rotate can synchronously drive the two vertical rods 221b. The two vertical rods 221b can synchronously move closer to or away from the middle of the horizontal plate 221a, which makes the center of gravity of the second suction device 220 and the base plate 10 on the second suction device 220 closer to the area connecting the horizontal plate 221a and the robot arm 210. This is beneficial for the smooth movement of the second suction device 220 and reduces the load on the robot arm 210.

[0050] It is conceivable that the second suction device 220 can eliminate the sliding mechanism and can be driven directly by the third linear drive mechanism to move the longitudinal rod 221b on the horizontal plate 221a.

[0051] Reference Figure 5 or Figure 8 The second suction device 220 also includes two sets of clamping plate assemblies 224, a first sliding member 225 and a first guide rail 226 that cooperate with each other. The second suction device 220 also includes a driving device 222. The two sets of clamping plate assemblies 224 are respectively configured as two clamping positions for clamping the substrate 10, and the clamping positions are the ends of the substrate 10.

[0052] Reference Figure 9 The clamping plate assembly 224 includes an upper clamping plate 224a and a lower clamping plate 224b that can rotate about a horizontal axis. The lower clamping plate 224b can rotate about a horizontal axis to move closer to or further away from the upper clamping plate 224a to clamp or release the clamping position of the substrate 10 in the vertical direction.

[0053] The first guide rail 226 is connected to the adapter frame 221, and the clamping plate assembly 224 is connected to the first sliding member 225. The clamping plate assembly 224 can slide on the first guide rail 226 so that the clamping plate assembly 224 is in a clearance position away from the clamping position of the substrate 10, or in a clamping position close to the clamping position of the substrate 10.

[0054] Reference Figure 7 The drive device 222 includes a third lifting drive mechanism 222a and a second guide rail 222b and a second sliding member 222c that cooperate with each other. The length direction of the second guide rail 222b extends horizontally, and the second sliding member 222c is connected to the first sliding member 225. (Refer to...) Figure 8The third lifting drive mechanism 222a is connected to the adapter frame 221. The output end of the third lifting drive mechanism 222a is connected to the second guide rail 222b. When the third lifting drive mechanism 222a drives the second guide rail 222b to rise, the clamping plate assembly 224 is in the avoidance position, and the lower clamping plate 224b moves away from the upper clamping plate 224a. After the suction cup assembly 223 picks up the substrate 10 from the support surface, the third lifting drive mechanism 222a drives the second guide rail 222b to fall. The clamping plate assembly 224 moves to the clamping position, the upper clamping plate 224a abuts against the upper surface of the clamping position, and the lower clamping plate 224b approaches the upper clamping plate 224a and abuts against the lower surface of the clamping position.

[0055] The output end of the third lifting drive mechanism 222a is connected to the second guide rail 222b. The third lifting drive mechanism 222a is configured to drive the second guide rail 222b to lift. When the third lifting drive mechanism 222a drives the second guide rail 222b to lift, the second guide rail 222b drives the second sliding member 222c to lift. Then the second sliding member 222c drives the first sliding member 225 to lift. Since the first sliding member 225 is slidably connected to the first guide rail 226, under the guidance and limiting action of the first guide rail 226, the first sliding member 225, the clamping plate assembly 224 and the second sliding member 222c move on the second guide rail 222b. That is, the clamping plate assembly 224 switches between the clamping position and the avoidance position.

[0056] The arrangement of the third lifting drive mechanism 222a, the second guide rail 222b, the second sliding member 222c, the first guide rail 226, and the first sliding member 225 enables the drive clamping plate assembly 224 to switch between the clamping position and the avoidance position. Only common components and a power source (the third lifting drive mechanism 222a) are needed to enable the drive clamping plate assembly 224 to perform relatively complex movements. The structure is relatively simple and easy to control.

[0057] The adapter frame 221 is connected to a protective cover, which covers the third lifting drive mechanism 222a, the second guide rail 222b, the second sliding member 222c, the first guide rail 226, the vertical plate 227, and the first sliding member 225. The protective cover serves to protect the third lifting drive mechanism 222a, the second guide rail 222b, the second sliding member 222c, the first guide rail 226, the vertical plate 227, and the first sliding member 225.

[0058] The upper clamping plate 224a and the lower clamping plate 224b can respectively abut against the upper and lower surfaces of the clamping position of the substrate 10 to clamp the substrate 10. The upper clamping plate 224a and the lower clamping plate 224b are distributed vertically, and the lower clamping plate 224b is rotated to open and close with the upper clamping plate 224a. Before or during the process of switching the clamping plate assembly 224 to the clamping position, the upper clamping plate 224a and the lower clamping plate 224b are in an open state, with the lower clamping plate 224b in a low position and away from the upper clamping plate 224a. When the clamping plate assembly 224 switches to the clamping position, the upper clamping plate 224a abuts against the upper surface of the substrate 10. Then, the lower clamping plate 224b rotates and moves closer to the substrate 10 until the lower clamping plate 224b abuts against the lower surface of the substrate 10. The upper clamping plate 224a and the lower clamping plate 224b then close, thereby clamping the end of the substrate 10. The lower clamping plate 224b rotates around a horizontal axis, which can prevent interference between the lower clamping plate 224b and the end of the substrate 10 when the clamping plate assembly 224 is switched to the clamping position.

[0059] It is conceivable that the outer surfaces of the upper clamping plate 224a and the lower clamping plate 224b have elastic layers, and the upper clamping plate 224a and the lower clamping plate 224b contact the substrate 10 through the elastic layers, reducing the risk of the substrate 10 being crushed.

[0060] The first sliding member 225, the first guide rail 226, the third lifting drive mechanism 222a, the second guide rail 222b, and the second sliding member 222c are configured to drive the clamping plate assembly 224 to move, so that the clamping plate assembly 224 can be in an abdication position away from the clamping position of the substrate 10 (e.g., Figure 8 (as shown) or in a clamping position close to the clamping position of the substrate 10 (such as...) Figure 5 As shown), when both sets of clamping plate assemblies 224 are in the clamping position, the two sets of clamping plate assemblies 224 respectively clamp the two ends of the substrate 10 on the suction cup assembly 223.

[0061] When the suction cup assembly 223 is not close to the substrate 10, the drive device 222 drives the clamping plate assembly 224 to move to the avoidance position. Then, the robot arm 210 drives the second suction device 220 to descend. The suction cup assembly 223 approaches the substrate 10 on the support surface of the output station of the preceding processing equipment and adsorbs the substrate 10. Then, the robot arm 210 drives the second suction device 220 to rise. The suction cup assembly 223 carries the substrate 10 to rise, so that the substrate 10 is detached from the support surface. There are no obstructions on the outside and bottom of the substrate 10. Then, the drive device 222 drives the clamping plate assembly 224 to move to the clamping position. The clamping plate assembly 224 can then clamp the end of the substrate 10 on the suction cup assembly 223. The suction cup assembly 223 and the clamping plate assembly 224 achieve two ways to fix the substrate 10, ensuring the firmness and stability of the second suction device 220 in transporting the substrate 10, reducing the risk of chip falling and the probability of equipment downtime, reducing the cost of producing circuit boards and improving production efficiency.

[0062] When it is necessary to place the substrate 10 on the support surface of the first tray, the second tray 400, the third tray 610 or the conveying device 120, the end of the substrate 10 can be released by the clamping assembly 224 first, then the clamping assembly 224 releases the substrate 10, the clamping assembly 224 moves from the clamping position to or switches to the avoidance position, and then the suction cup assembly 223 releases the substrate 10, so that the substrate 10 can be placed on the support surface of the first tray, the second tray 400, the third tray 610 or the conveying device 120.

[0063] The clamping and clearance positions of the clamping plate assembly 224 are designed to be suitable for use with the current output station, the first tray, the second tray 400, and the third tray 610, and to prevent interference between the clamping plate assembly 224 and the side walls of the output station, the first tray, the second tray 400, and the third tray 610.

[0064] In some of these embodiments, reference is made to Figure 6 The suction cup assembly 223 includes a guide rod 223a, a mounting plate 223c, an elastic element 223d, and multiple suction cups 223e. The upper end of the guide rod 223a is slidably connected to the vertical rod 221b, and the upper end of the guide rod 223a is connected to a limiting block 223b, which can abut against the vertical rod 221b. The lower end of the guide rod 223a is connected to the mounting plate 223c, and the multiple suction cups 223e are connected to the lower end of the mounting plate 223c. The multiple suction cups 223e are all arranged downward and are coplanar. The two ends of the elastic element 223d are respectively connected to or abut against the vertical rod 221b and the mounting plate 223c. Mounting plate 223c is connected to vertical rod 221b via guide rod 223a and limiting block 223b. Initially, elastic element 223d is in a stretched state, which forces vertical rod 221b and mounting plate 223c to move away from each other, so that mounting plate 223c and multiple suction cups 223e are in a lower position.

[0065] When the vertical rod 221b rises, the limiting block 223b abuts against the vertical rod 221b. The vertical rod 221b drives the limiting block 223b to rise, and then the limiting block 223b drives the guide rod 223a, the mounting plate 223c, and multiple suction cups 223e to rise. The suction cups 223e can then carry the substrate 10 to rise. The vertical rod 221b carries the limiting block 223b, the guide rod 223a, the mounting plate 223c, and the multiple suction cups 223e to descend. When the suction cups 223a and 223c descend, the vertical rod 221b carries the limiting block 223b, the guide rod 223a, the mounting plate 223c, and the multiple suction cups 223e to descend. When the suction cup 223e rests against the upper surface of the substrate 10, the substrate 10 supports the suction cup 223e, the mounting plate 223c, and the guide rod 223a. At this time, if the vertical rod 221b continues to descend, the vertical rod 221b descends relative to the mounting plate 223c, the limiting block 223b disengages from the vertical rod 221b, the guide rod 223a slides relative to the vertical rod 221b, and the elastic element 223d is compressed, so that the suction cup assembly 223 has a buffering function to prevent the suction cup assembly 223 from crushing the substrate 10.

[0066] The elastic element 223d is a spring, which is sleeved on the guide rod 223a. The upper end of the spring abuts against the lower surface of the longitudinal rod 221b, and the lower end of the spring abuts against the upper surface of the mounting plate 223c.

[0067] It is understandable that the two longitudinal bars 221b are symmetrically distributed in the left-right direction, and the two sets of clamping plate assemblies 224 are symmetrically distributed in the left-right direction. Of course, the two sets of clamping plate assemblies 224 can also be symmetrically distributed in the front-back direction.

[0068] In some embodiments, the adapter 221 is equipped with a positioning sensor 229, which is used to detect the substrate 10. When the substrate 10 is in the triggered position of the positioning sensor 229, the positioning sensor 229 is triggered, and the suction cup assembly 223 stops moving toward the substrate 10. That is, the robot arm 210 stops driving the second suction device 220 to move. At this time, the suction cup assembly 223 abuts against the upper surface of the substrate 10, and the upper clamping plate 224a abuts against the upper surface of the clamping position. When the positioning sensor 229 is triggered, the robot arm 210 stops driving the first suction device to move, which can prevent the suction cup assembly 223 from crushing the substrate 10.

[0069] In some of these embodiments, reference is made to Figure 7 The first guide rail 226 includes a vertical section 226a and a curved section 226b. The upper end of the vertical section 226a is connected to the lower end of the curved section 226b. The upper end of the curved section 226b is curved upward between the two sets of suction cup assemblies 223. The first sliding member 225 can slide on the vertical section 226a and the curved section 226b to switch the clamping plate assembly 224 between the clamping position and the avoidance position.

[0070] The vertical section 226a and the curved section 226b serve to guide and limit the movement of the first sliding member 225 and the clamping plate assembly 224. When the first sliding member 225 moves on the vertical section 226a, the first sliding member 225 and the clamping plate assembly 224 move up and down. When the first sliding member 225 moves to the lower end of the vertical section 226a, the clamping plate assembly 224 moves to the clamping position. When the first sliding member 225 moves on the curved section 226b, the first sliding member 225 and the clamping plate assembly 224 move down while moving away from the center between the two sets of suction cup assemblies 223. The first sliding member 225 and the clamping plate assembly 224 move up while moving closer to the upper part between the two sets of suction cup assemblies 223. When the first sliding member 225 moves to the upper end of the curved section 226b, the clamping plate assembly 224 moves to the avoidance position.

[0071] Furthermore, the curved section 226b can be arc-shaped. Alternatively, the curved section 226b can be an inclined straight guide rail.

[0072] In some of these embodiments, reference is made to Figure 7 The adapter 221 is connected to a vertical plate 227 (specifically, the vertical plate 227 is connected to the longitudinal rod 221b). The first guide rail 226 is a groove opened on the vertical plate 227. The first sliding member 225 extends into the groove, and the inner wall of the groove plays a role in limiting and guiding the first sliding member 225.

[0073] In some of these embodiments, reference is made to Figure 5 and Figure 7 The second suction device 220 also includes a sliding frame 228, a clamping plate assembly 224 connected to the sliding frame 228, and the sliding frame 228 connected to the first sliding member 225. A rotating wheel 225a is rotatably connected to the first sliding member 225. The rotating wheel 225a is housed in a groove and abuts against the inner wall of the groove. The depth direction of the groove and the axial direction of the rotating wheel 225a are parallel to each other. The rotating wheel 225a can rotate, so that the first sliding member 225, the sliding frame 228, and the clamping plate assembly 224 can move in the groove. The friction between the first sliding member 225 and the vertical plate 227 is small, thereby reducing the resistance encountered by the first sliding member 225, the sliding frame 228, and the clamping plate assembly 224 when they move.

[0074] In some of these embodiments, reference is made to Figure 5 Two sets of clamping plate assemblies are distributed approximately 224, as per reference. Figure 8 or Figure 9The planes of the vertical section 226a and the curved section 226b are perpendicular to the front-back direction. The length of the second guide rail 222b extends in the left-right direction. When the third lifting drive mechanism 222a drives the second guide rail 222b to lift, the second guide rail 222b drives the second sliding member 222c to lift. Then, the second sliding member 222c drives the first sliding member 225 to lift. Since the first sliding member 225 is slidably connected to the vertical section 226a and the curved section 226b, under the guidance and limiting action of the vertical section 226a and the curved section 226b, the first sliding member 225, the clamping plate assembly 224 (including the sliding frame 228), and the second sliding member 222c move in the up-down and left-right directions on the second guide rail 222b. That is, the clamping plate assembly 224 switches between the clamping position and the avoidance position.

[0075] It is understood that each set of clamping plate assemblies 224 includes multiple clamping plate assemblies 224, and the multiple clamping plate assemblies 224 in the same set are distributed on the sliding frame 228 in the front-back direction. There are two sets of vertical plates 227, which are distributed left and right. Each set has two vertical plates 227, and the two vertical plates 227 in each set are parallel to the front-back direction. Each vertical plate 227 is provided with a groove. There are two sliding frames 228. The two sets of clamping plate assemblies 224 are respectively connected to the two sliding frames 228. The two sliding frames 228 are respectively connected to two first sliding members 225. The front and rear ends of the first sliding members 225 are rotatably connected to the rotating wheels 225a. The depth direction of the groove and the axial direction of the rotating wheels 225a are parallel to the front-back direction. The two rotating wheels 225a on the sliding frame 228 are respectively housed in the two grooves on the two vertical plates 227 in the same set.

[0076] Reference Figure 8 and Figure 9 The third lifting drive mechanism 222a is connected to the longitudinal rod 221b. The vertical plate 227 is connected to the longitudinal rod 221b.

[0077] In some of these embodiments, reference is made to Figure 9The upper clamping plate 224a has an upper connecting portion and an upper clamping portion, and the lower clamping plate 224b has an actuating portion, a lower connecting portion, and a lower clamping portion arranged sequentially. The lower connecting portion is rotatably connected to the upper connecting portion in a horizontal direction (specifically, a front-to-back direction), allowing the lower clamping plate 224b to rotate on the upper clamping plate 224a. This allows the upper and lower clamping portions to move closer to or further away from each other, i.e., the upper and lower clamping portions open and close. Before the clamping plate assembly 224 moves to the clamping position, the lower clamping portion moves away from the upper clamping portion, and the upper and lower clamping portions are in an open state. When the clamping plate assembly 224 moves to the clamping position, the upper connecting portion, the actuating portion, the lower connecting portion, and the lower clamping portion are all located outside the clamping position. The upper clamping portion abuts against the upper surface of the clamping position, and then the lower clamping portion moves closer to the upper clamping portion and abuts against the lower surface of the clamping position, so that the clamping plate assembly 224 achieves the clamping position of the substrate 10.

[0078] In some of these embodiments, reference is made to Figure 9 The clamping plate assembly 224 also includes a fourth lifting drive mechanism 224c. The body of the fourth lifting drive mechanism 224c is connected to the first sliding member 225, and the upper connecting part is connected to the body of the fourth lifting drive mechanism 224c. The output end of the fourth lifting drive mechanism 224c faces downward and is hinged to a connecting rod. The connecting rod is hinged to an actuating part. The fourth lifting drive mechanism 224c drives the lower clamping plate 224b to rotate through the connecting rod, so that the lower clamping part moves closer to or away from the upper clamping part, thereby clamping or releasing the end of the substrate 10.

[0079] The first lifting drive mechanism, the second lifting drive mechanism 320, the third lifting drive mechanism 222a, the fourth lifting drive mechanism 224c, the first linear drive mechanism 620, and the second linear drive mechanism 310 can all be one of a cylinder, a hydraulic cylinder, an electric actuator, and a lead screw.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
