[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a pickling and grinding device for circuit board production, which has the following beneficial effects:

[0021] The pickling and grinding device for circuit board production has the following advantages: when the circuit board workpiece is completely immersed in the box, the lifting rod drives the bearing plate to rise to the top of the cavity, and then the first lifter is started to lower the first motor, so that the grinding wheel can contact the circuit board workpiece, and then the pusher is started to move the grinding wheel on the circuit board workpiece, so that the circuit board workpiece can be polished. In this process, it is not necessary to manually take the circuit board out of the box, which not only saves labor but also has a high degree of automation, thereby improving the processing efficiency of the circuit board;

[0022] When the vacuum cleaner is started, suction is generated at the vacuum pipe. At this time, the grinding debris will be sucked into the vacuum pipe and then collected inside the vacuum cleaner, so that the grinding debris and impurities will not fall into the box and the processing table will be tidier.

[0023] When the circuit board workpiece rises in the box, the air pump is started, so that the air outlet pipe can provide a drying effect for the circuit board workpiece, so that the circuit board workpiece will not carry too much liquid before grinding. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-6The present invention discloses a pickling and grinding device for circuit board production, comprising a processing table 1, a cavity 2 is provided in the middle of the processing table 1, a box body 3 is provided below the cavity 2, a discharge pipe 4 is provided at the lower end of the box body 3, and a valve is provided on the discharge pipe 4;

[0033] Two positioning frames 10 are symmetrically arranged inside the box body 3, and a slide groove 11 is arranged on the positioning frame 10. A carrying plate 13 is arranged above the cavity 2, and a plurality of guide grooves 15 are symmetrically arranged on the carrying plate 13. A guide block 20 is slidably arranged in the guide groove 15, and a second motor 22 is arranged at the upper end of the guide block 20. A positioning seat 19 is fixedly arranged at the lower end of the carrying plate 13, and a rotating shaft 17 is rotatably arranged on the positioning seat 19. Two screws 18 with reverse thread structures are symmetrically arranged on the rotating shaft 17, and the screw 18 passes through the guide block 20, and the screw 18 is threadedly matched with the guide block 20. Slide blocks 14 that slide with the slide groove 11 are arranged on both sides of the carrying plate 13. A second lifter 12 is fixedly arranged on the upper end of the positioning frame 10, and a lifting rod that passes through the positioning frame 10 and is connected to the slide block 14 is arranged at the output end of the second lifter 12;

[0034] A propeller 5 is fixedly arranged above the processing table 1, a first lifter 6 is arranged at the output end of the propeller 5, a first motor 7 is arranged at the output end of the first lifter 6, and a grinding wheel 8 is arranged at the output end of the first motor 7;

[0035] In this embodiment, the circuit board workpiece is placed on the carrier plate 13, and then the first motor 7 is rotated to rotate the two screws 18. Through the action of the reverse thread structure, the two clamping blocks 16 can be synchronously moved in opposite directions on the carrier plate 13, so that the two clamping blocks 16 can clamp the circuit board workpiece on the carrier plate 13, so that the circuit board workpiece can be placed on the carrier plate 13 more firmly.

[0036] Starting the second lifter 12 can make the lift rod drive the slider 14 to descend in the slide groove 11, so that the carrier plate 13 can be lowered into the box body 3. At this time, the circuit board workpiece can be pickled and soaked in the box body 3. When the circuit board workpiece has been soaked in the box body 3, the lift rod drives the carrier plate 13 to rise above the cavity 2, and then start the first lifter 6 to make the first motor 7 descend, so that the grinding wheel 8 can contact the circuit board workpiece, and then the pusher 5 is started, so that the grinding wheel 8 can move on the circuit board workpiece, and then the circuit board workpiece can be polished. This process does not require manual removal of the circuit board from the inside of the box body 3, which not only saves labor but also has a high degree of automation, thereby improving the processing efficiency of the circuit board.

The dust suction pipe 21 is connected to the dust suction end of the vacuum cleaner 9 through a first guide tube. When the circuit board workpiece is being polished, the vacuum cleaner 9 is started, and suction can be generated at the dust suction pipe 21.
