At present, during the working process of PCB sheet processing equipment, PCB sheets need to be continuously picked up and placed, and these operations are usually completed manually; in this process, the operator needs to use both hands to move the PCB sheets up and down multiple times. However, with the gradual increase in the size of the currently processed PCB sheets, it is particularly difficult to pick up and place large-format PCB sheets, which will result in problems such as long replacement time and inconvenient operation. Therefore, a device needs to be designed to realize the automatic loading, unloading and transfer of PCB sheets, so as to improve the processing efficiency and accuracy of PCB sheets.

[0033] In this embodiment, the PCB sheet and bakelite base separation mechanism 5 includes a separation mechanism frame body 51 with a separation mechanism installation cavity 511 formed inside.

When the PCB sheet separation and ejection mechanism 53 moves upward, the PCB sheet separation and ejection mechanism 53 passes through the PCB sheet separation and transfer mechanism 52.
[0034] The PCB sheet separation and transfer mechanism 52 includes a separation and transfer mechanism frame body 521. Inside the separation and transfer mechanism frame body 521, there is a separation cavity 522 for the PCB sheet separation and ejection mechanism 53 to pass through.

At the end of the up-and-down movement piston 5234 away from the transfer air cylinder body 5231, there is a transfer top plate 5235. On the rotary air cylinder head 5233, there is a transfer rotary assembly 5236 that passes through the up-and-down movement air cylinder head 5232 and is connected to the up-and-down movement piston 5234 to drive the up-and-down piston to rotate. The transfer rotary assembly 5236 includes a transfer rotary piston 52361 and a transfer guide rod 52362 connected to the transfer rotary piston 52361. The transfer rotary piston 52361 is connected to the rotary air cylinder head 5233, and the transfer guide rod 52362 is connected to the up-and-down piston. The PCB sheet separation and ejection mechanism 53 includes a lifting drive assembly and an ejection plate 531. The lifting drive assembly is arranged inside the separation mechanism installation cavity 511 and drives the ejection plate 531 to move up and down along the separation mechanism installation cavity 511. On the ejection plate 531, there are several ejection rods 532.
[0035] In this embodiment, the separated PCB sheet transportation mechanism 7 includes a separated PCB sheet transportation frame 71 and a separated PCB sheet transportation component 72 arranged inside the separated PCB sheet transportation frame 71.
[0036] The identification and isolation component 13 of this device is a photoelectric inductor.
[0037] The first bakelite base lifting mechanism 4 and the second bakelite base lifting mechanism 6 are used to realize the circulation of the bakelite base through lifting. The first bakelite base lifting mechanism 4 transports the bakelite base to the assembly position by rising to realize the assembly of the PCB sheet and the bakelite base; the second bakelite base lifting mechanism 6 sends the bakelite base from which the PCB sheet has been processed and separated to the inside of the first bakelite base lifting mechanism 4 by descending to realize the circulation of the bakelite base. Since two limit plates 442 are required to limit the movement of the bakelite base moving seat 44, and at the same time the moving seat base 441 needs to move up and down inside the bakelite conveyor seat 42; therefore, when assembling the bakelite base moving seat 44, the limit plates 442 and the moving seat base 441 need to pass through the conveyor seat limit through slots 422 and the conveyor seat through slots 4211 respectively before assembly.
[0038] For example, the bakelite base lifting mechanism is used to transport the bakelite base to the assembly position by rising to realize the assembly of the PCB sheet and the bakelite base; in the initial state, the upper surface of the bakelite base moving seat 44 is located below the upper surface of the bakelite conveyor seat 42, and at the same time the bakelite base is placed on the bakelite conveyor seat 42. If the assembly of the PCB sheet is required, the lifting assembly 45 is started, and the slider 432 of the guide rail assembly 43 is displaced in the slide rail 431, thereby driving the bakelite base moving seat 44 to move up. Each moving plate 4411 of the moving seat base 441 passes through two groups of adjacent conveyor seat rollers 423 of the bakelite conveyor seat 42, thereby lifting the bakelite base and transporting the bakelite base to the subsequent assembly position. During this process, the first moving wheel 4412 and the second moving wheel 4423 are used to assist in the transportation of the bakelite base.
[0039] The PCB sheet separating and ejecting mechanism 53 is used to separate the processed PCB stacked sheets and the base, and separate them into cardboard, the processed PCB sheets and the bakelite base. To achieve the separation effect, separation holes need to be pre-set on the bakelite base, and the ejector rods 532 of the PCB sheet separating and ejecting mechanism 53 need to be set corresponding to the positions and quantities of the separation holes.
[0040] When the PCB sheet and bakelite base separation mechanism 5 is working, the lifting drive assembly of the PCB sheet separation and ejection mechanism 53 is activated, driving the ejection plate 531 to move upward. The ejection rods 532 on the ejection plate 531 extend into the separation holes of the bakelite base, thereby separating the PCB stacked sheets and the base into cardboard, processed PCB sheets, and bakelite bases. During this process, the PCB sheet separation and ejection mechanism 53 passes through the PCB sheet separation and transfer mechanism 52. After the separation is completed, compressed air is introduced into the transfer cylinder body 5231, and the reciprocating piston 5234 drives the transfer top plate 5235 to move upward to a position close to the bottom surface of the cardboard and the processed PCB sheets; the transfer rotary piston 52361 drives the transfer top plate 5235 to rotate through the transfer guide rod 52362 and rotates it to the bottom of the cardboard and the processed PCB sheets. The reciprocating piston 5234 continues to drive the transfer top plate 5235 to move upward, sending the cardboard and the processed PCB sheets to the separated PCB sheet transportation mechanism 7. During this process, since there are several PCB sheet transfer manipulators 523, the stability of the transportation of the cardboard and the processed PCB sheets can be ensured. Subsequently, the cardboard and the processed PCB sheets are manually removed and separated into PCB sheets and cardboard.
[0041] The above-described embodiments merely represent the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
