The automatic in-and-out device is connected to the first station of the circuit production line via the frame input mechanism 13, and is connected to the second station of the circuit production line via the frame output mechanism 14. A temporary storage box 10 fixedly installed on the frame 1 and a movable frame 10 movably mounted on the upper part of the frame 1 are arranged between the frame input mechanism 13 and the frame output mechanism 14. The material transfer mechanism 12 has soaking liquid injected into the temporary storage box 10. The material transfer mechanism 12 includes a plate frame picking unit 120, a plate frame lifting mechanism 121 and a transverse pick-up and placement mechanism 123. The plate frame picking unit 120 is used to pick up and fix the plate frame 11. The plate frame lifting mechanism 121 is used to drive the plate frame picking unit 120 to rise and fall so as to place the plate frame 11 into or move it out of the temporary storage box 10. The transverse pick-up and placement mechanism 123 is used to drive the plate frame picking unit 120 to move to the plate frame input mechanism 13 to take the frame or move it to the lower frame of the plate frame output mechanism 14.

[0023] The present invention uses a plate frame 11 to carry or clamp a plurality of circuit boards at one time. The plate frame picking unit 120 is used to pick up and fix the plate frame 11. The plate frame pick-up and placement mechanism 123 drives the plate frame picking unit 120 to move from the plate frame input mechanism 13 to the top of the temporary storage box 10. The plate frame 11 is temporarily stored in the temporary storage box 10 by using the plate frame lifting mechanism 121. The circuit boards are immersed in a water bath and prevented from oxidation by the soaking liquid in the temporary storage box 10. Of course, in other schemes, the temporary storage box 10 can also be injected with a circuit board cleaning liquid to clean the circuit boards, or an electroplating liquid can be injected for electroplating of the circuit boards. It has strong versatility and can be assembled in the corresponding process according to the actual needs of the production line.

[0024] Specifically, the plate frame picking unit 120 includes a lifting base 1225 driven and connected to the plate frame lifting mechanism 121 and a frame taking device 122 installed on the lifting base 1225.

The frame taking power member 1224 is used to lift the frame taking base 1220 up and down so that the insertion ridge 12260 of the protrusion 1226 is inserted into the hanging groove 110 of the plate frame 11.

Among them, the distance adjustment component 1222 generally adopts a distance adjustment cylinder, and the number of the distance adjustment cylinders is at least two. One distance adjustment cylinder drives one frame removal slide 1221 to slide relatively, thereby adjusting the relative position of the two insertion ridges 12260, so as to be suitable for picking up plate frames 11 of different sizes.

[0026] Specifically, the plate frame picking unit 120 has two frame picking stations, each of which is equipped with a frame picking device 122, and the two frame picking devices 122 are selectively used or used in rotation. In actual application, users can increase or decrease the number of plate frames 11 according to their own needs to optimize the production efficiency of the production line to the greatest extent.

[0027] Specifically, the board frame 11 is provided with a plurality of board slots for vertically inserting circuit boards at intervals. The upper portion of the board frame 11 has a hook 111, and the hook 111 has a hanging slot 110 extending longitudinally. A stop ridge 116 is formed at a position of the hook 111 corresponding to the hanging slot 110 and is inclined relative to the hanging slot 110.

In actual applications, the transverse frame 1231 is driven to slide by the transverse screw nut mechanism 1230, so that the plate frame picking unit 120 installed on the lifting seat can slide as a whole to pick up or put down the plate, and the lifting screw nut mechanism 1211 is used to drive the lifting base 1225 to slide up and down, so that the plate frame 11 hung on the hanging frame device 122 can be placed up and down in the temporary storage box 10.

[0030] More specifically, the transverse movement pick-and-place mechanism 123 further includes transverse guide rails 1232 respectively installed on the frame 1 , and the transverse movement frame 1231 is installed with a transverse movement slide 1233 that slidably cooperates with the transverse guide rails 1232 .
