[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts.

[0003] Circuit board processing and transfer devices are a type of equipment that places, transfers and transports circuit boards. They are mainly used to support and transfer circuit boards that are to be processed or have been processed, so that they can be subsequently processed.

[0004] Currently, most of the common circuit board transfer devices are mainly transfer carts. When in use, the circuit boards to be transferred are transported by manual handling. At the same time, the circuit boards can be clamped and fixed by configuring corresponding clamping mechanisms, and then the circuit boards are transferred.

[0005] Although this type of circuit board transfer device can transfer circuit boards, it requires manual loading and unloading and clamping of the circuit boards during use. This not only makes the circuit board transfer process more cumbersome and complicated, but also the presence of precision components on the circuit boards, and manual transfer poses greater safety risks, making the transfer of circuit boards less safe.

[0006] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

The driving motor 206 provides power, and the assembly rack 202 is rotationally driven by controlling the operation of the driving motor 206.

[0032] like Figures 4 to 5 As shown, a pair of tensioning driving rollers 203 are rotatably mounted between the multiple assembly racks 202. The tensioning driving rollers 203 play the role of tensioning, limiting and moving control on the transfer belt 204.

[0033] like Figures 4 to 5 As shown, multiple groups of evenly distributed auxiliary support rollers 207 are arranged between a pair of tension drive rollers 203, and both ends of the multiple groups of auxiliary support rollers 207 are rotatably connected to the assembly frame 202. The multiple groups of auxiliary support rollers 207 play an auxiliary supporting role for the transfer belt 204, thereby improving the stability of the transfer belt 204 in supporting and transferring the circuit board.

[0034] like Figures 4 to 5 As shown, a pair of tension drive rollers 203 are sleeved with a transfer belt 204 on their outer sides. The transfer belt 204 is moved to support and transfer the circuit board, thereby facilitating automatic loading and unloading of the circuit board, simplifying the convenience of loading and unloading the circuit board.

[0036] like Figures 4 to 5As shown, one side of the multiple assembly racks 202 is fixedly mounted with an assembly limit assembly. The assembly limit assembly includes a pair of limit seats 208, and the pair of limit seats 208 are fixedly mounted on one side of the assembly rack 202. The limit seats 208 play the role of assembly limit for the guide locking plate 209.

[0037] like Figures 4 to 5 As shown, a guide locking plate 209 is hinged between a pair of limiting seats 208. The circuit board to be transferred is supported and limited by the guide locking plate 209. At the same time, the circuit board placed on the transfer belt 204 is prevented from falling off by the guide locking plate 209 being placed vertically.

[0038] like Figures 4 to 5 As shown, a pair of limit seats 208 are fixedly assembled with a limit bottom plate 210 below, and the limit bottom plate 210 is arranged in cooperation with the guide locking plate 209. The limit bottom plate 210 supports and limits the guide locking plate 209, thereby improving the stability of the transfer belt 204 in supporting and placing the circuit board.

[0040] like Figures 2 to 3 As shown, multiple groups of pneumatic clamping and fixing mechanisms 3 are assembled above the conveyor belt 204. The pneumatic clamping and fixing mechanisms 3 include a pair of clamping and fixing plates 301. The pair of clamping and fixing plates 301 are both slidably assembled above the conveyor belt 204. By controlling the movement of the pair of clamping and fixing plates 301, the circuit board placed on the conveyor belt 204 is clamped and limited, thereby improving the stability of the circuit board transportation.

[0041] like Figures 2 to 3 As shown, a pair of clamping and fixing plates 301 have positioning air cushions 302 attached to their corresponding sides. The positioning air cushions 302 are deformed to assist in clamping and limiting the circuit board, thereby improving the stability of clamping and fixing the circuit board.

[0042] like Figures 7 and 8 As shown, a drive control assembly is fixedly mounted on one side of the clamping fixed plate 301, and the drive control assembly includes a drive control box 303. The drive control box 303 is fixedly mounted on the side of the storage partition 201 away from the guide locking plate 209. The drive control box 303 is used to perform assembly limit and movement control on the mobile control block 304. At the same time, the drive control box 303 provides assembly and operation space for the drive gear 306 and the transmission gear 307.

[0043] like Figures 7 to 10As shown, a pair of clamping and fixing plates 301 are integrally formed with a moving control block 304 at one end away from the guide locking plate 209. The clamping and fixing plates 301 are supported and limited by assembling and limiting the moving control block 304. At the same time, the clamping and fixing plates 301 can be moved and controlled by driving and controlling the moving control block 304.

[0044] Specifically, a plurality of evenly distributed assembly limit grooves are cut on one side of the drive control box 303 close to the storage partition 201, and the assembly limit grooves are arranged in cooperation with the movement control block 304. The assembly limit grooves play the role of assembly limit for the movement control block 304.

[0045] like Figures 7 to 10 As shown, a plurality of driving shafts 305 are rotatably connected in the driving control box 303, and the driving shafts 305 penetrate through a plurality of movement control blocks 304. The driving shafts 305 play the role of supporting, limiting and moving control for the plurality of movement control blocks 304.

[0046] It is worth noting that the outer side of the driving shaft 305 is bored with multiple sets of external threads in opposite directions, and the inner side of the pair of moving control blocks 304 is bored with internal threads in the same direction. Through the cooperation of the internal and external threads, the pair of moving control blocks 304 can drive the clamping and fixing plates 301 to move in opposite directions as the driving shaft 305 rotates, so that the batteries placed on the conveyor belt 204 can be clamped and limited by the pair of clamping and fixing plates 301.

[0047] like Figures 7 and 8 As shown, one side of the plurality of driving shafts 305 is fixedly connected to a driving gear 306. The driving gear 306 plays a role of rotationally driving the driving shaft 305. The movement of the clamping fixed plate 301 is controlled by controlling the rotation of the driving shaft 305.

[0048] like Figures 7 and 8 As shown, a transmission gear 307 is meshed on one side of the driving gear 306. The transmission gear 307 plays a role in transmitting the power of the clamping motor 308, so that the driving gear 306 can rotate synchronously with the rotation of the output shaft of the clamping motor 308 under the action of the transmission gear 307.

[0049] like Figures 7 and 8 As shown, a plurality of evenly distributed clamping motors 308 are fixedly mounted on one side of the drive control box 303, and the output shafts of the clamping motors 308 are in transmission connection with the transmission gear 307. The clamping motors 308 provide power, and the transmission gear 307 is driven to rotate by controlling the operation of the clamping motors 308.

[0050] like Figures 6 to 8As shown, a plurality of buffer air cushions 309 are sleeved on the outer side of the driving shaft 305, and the plurality of buffer air cushions 309 are arranged between a pair of moving control blocks 304. The shrinkage and resetting of the plurality of buffer air cushions 309 play a role of moving buffer for the moving control block 304. At the same time, the buffer air cushions 309 can play a role of sleeve protection for the driving shaft 305. In addition, the buffer air cushions 309 play a role of storing gas, and the gas can be transported into the positioning air cushion 302 by squeezing the buffer air cushion 309, thereby ensuring the effect of the positioning air cushion 302 on clamping and limiting the circuit board.

[0051] like Figures 6 to 8 As shown, a conducting air pipe 310 is connected between the buffer air cushion 309 and the positioning air cushion 302. The conducting air pipe 310 serves to connect the buffer air cushion 309 and the positioning air cushion 302, so as to facilitate gas conduction between the buffer air cushion 309 and the positioning air cushion 302.

[0052] like Figures 9 and 10 As shown, a plurality of sets of auxiliary limiting mechanisms 4 are fixedly assembled above the transfer belt 204, and the auxiliary limiting mechanisms 4 are used for auxiliary fixed limiting.

[0053] like Figures 9 and 10 As shown, the auxiliary limiting mechanism 4 includes a limiting top plate 401, which is arranged above the transfer belt 204 and between a pair of clamping fixing plates 301. The limiting top plate 401 plays a role in assembling, fixing and moving control of the fixed air cushion 402.

[0054] like Figures 9 and 10 As shown, a fixed air cushion 402 is fixedly attached to one side of the limiting top plate 401 close to the transfer belt 204. The fixed air cushion 402 and the limiting top plate 401 cooperate with each other to limit the top position of the circuit board, thereby ensuring the stability of the clamping and limiting of the circuit board and reducing the shaking and collision of the circuit board during the transportation process.

[0055] like Figures 9 and 10 As shown, both sides of the limit top plate 401 are provided with moving cylinders 403. The telescopic state of the piston rod is controlled by delivering gas into the moving cylinders 403, so as to facilitate the control of the moving clamping process of the limit top plate 401.

[0056] like Figures 9 and 10 As shown, a fixed connection block 404 is fixedly connected between the piston rod of the mobile cylinder 403 and the limit top plate 401. It is convenient for the limit top plate 401 to move synchronously with the movement of the piston rod of the mobile cylinder 403 under the action of the fixed connection block 404.

[0057] like Figures 9 and 10As shown, a communication air pipe 405 is connected between the moving cylinder 403 and the buffer air cushion 309. The moving cylinder 403 and the buffer air cushion 309 are connected and conducted through the communication air pipe 405.

[0058] When in use, the transfer chassis 1 is moved to the position where the circuit board is to be transferred by manually supporting the transfer handrail 102, and the tension drive roller 203 is driven to rotate by controlling the operation of the drive motor 206. Under the action of the tension drive roller 203, the transfer belt 204 moves synchronously with the rotation of the output shaft of the drive motor 206. Subsequently, the circuit board to be transferred is moved onto the guide locking plate 209, and the circuit board placed on the guide locking plate 209 is supported and moved by the movement of the transfer belt 204 and the limiting partition 205.

[0059] The circuit boards are automatically loaded through the conveyor belt 204 , and at the same time, the circuit boards supported on the conveyor belt 204 can be auxiliary limited by the limiting partitions 205 and the storage partitions 201 .

[0060] When the circuit board is moved into the transfer storage chamber, the transmission gear 307 can be driven to rotate by controlling the operation of the clamping motor 308, and the driving shaft 305 can rotate synchronously under the action of the driving gear 306 and the transmission gear 307. A pair of moving control blocks 304 move in opposite directions under the action of internal and external threads, and the clamping and fixing plate 301 can move synchronously with the movement of the moving control block 304, and the circuit board is clamped and limited by a pair of clamping and fixing plates 301.

[0061] During the movement of a pair of clamping and fixing plates 301, the buffer air cushion 309 can be compressed as the moving control block 304 moves, and the gas in the buffer air cushion 309 can be transported to the positioning air cushion 302 along the air pipe 310. The expansion and deformation of the positioning air cushion 302 can assist in clamping and limiting the circuit board.

[0062] At the same time, when the buffer air cushion 309 is squeezed, the gas in the buffer air cushion 309 can be transported to the mobile cylinder 403 along the connecting air pipe 405. By transporting gas to the mobile cylinder 403, the limiting top plate 401 can be raised and lowered along with the movement of the piston rod in the mobile cylinder 403 under the action of the fixed connecting block 404. By controlling the lifting and lowering of the limiting top plate 401 and the fixed air cushion 402, the top of the circuit board can be fixed and limited, thereby ensuring the stability of the clamping and limiting of the circuit board and improving the stability of the transportation of the circuit board.

[0063] When the circuit board needs to be unloaded, the circuit board can be assisted in unloading by reversely controlling the operation of the clamping motor 308 and the driving motor 206, thereby improving the convenience of unloading the circuit board.

[0064] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
