[0028] In one embodiment, the hanging assembly 2 includes two support plates 201, and the surfaces of both sides of one of the support plates 201 are respectively fixedly connected with a rotating shaft 1 202 and a positive and negative motor plate 208, one side of one of the support plates 201 is provided with a bearing hole 1 204, and one side of the other support plate 201 is fixedly connected with two rotating shafts 1 202, the surfaces of the three rotating shafts 1 202 are all connected with pulleys 1 203 through bearings, the interior of the bearing hole 1 204 is connected with a rotating shaft 205 through a bearing, and the surface of the other end of the rotating shaft 205 is fixedly sleeved with a pulley 206, One end of the second shaft 205 is connected to a forward and reverse motor 207, the output end of the forward and reverse motor 207 is fixedly embedded in one end of the second rotating shaft 205, the bottom of the forward and reverse motor 207 is fixedly connected to the surface of the forward and reverse motor plate 208, one side of the two support plates 201 is provided with a bearing hole 209, the inside of the two bearing holes 209 is connected with a connecting rod 1 210 through a bearing, the surface of the connecting rod 1 210 is fixedly sleeved with a connecting rod 211, the bottom of the connecting rod 211 is provided with four fitting grooves 1 212, and the inside of the four fitting grooves 1 212 are fixedly connected with permanent magnets 213.

[0029] Specifically: when pulley 206 moves forward under the drive of the forward and reverse motor 207, the three pulleys 1 203 follow and move forward, so that the hanging component 2 can move on the surface of the hanging track 1. The top sides of the two support plates 201 are provided with movable grooves, which can provide movable space at the corners when moving to the corners and avoid obstruction caused by tilting.

[0030] In one embodiment, the clamping assembly 3 includes a connecting rod three 301, four fitting grooves two 308 are provided on the surface of the connecting rod three 301, a clamp plate one 302 is fixedly connected to the bottom of the connecting rod three 301, a bearing hole three 303 is provided on the surface of the clamp plate one 302, a limiting rod 304 is fixedly connected to the bottom of the clamp plate one 302, a knob bolt 305 is connected to the inside of the bearing hole three 303 through a bearing, a clamp plate two 306 is threadedly connected to the surface of the knob bolt 305, a limiting hole 309 is provided on the surface of the clamp plate two 306, the surface of the limiting rod 304 is movably embedded in the inside of the limiting hole 309, and a plurality of silicone strips 307 are fixedly connected to one side of the clamp plate one 302 and the clamp plate two 306.

[0031] Specifically, the limiting hole 309 and the limiting rod 304 cooperate to limit the movement of the second clamping plate 306, so that the second clamping plate 306 can only move up and down but not rotate.

[0032] In one embodiment, the surfaces of three pulleys 1 203 and pulley 2 206 are movably embedded inside the suspension track 1 .

[0033] Specifically, when the pulley 206 moves forward under the drive of the forward and reverse motor 207 , the three pulleys 1 203 follow and move forward, so that the hanging component 2 moves on the surface of the hanging track 1 .

[0034] In one embodiment, the interior of the second engaging groove 308 is movably embedded in the surface of the bottom of the first engaging groove 212 .

[0035] Specifically: the top of the connecting rod three 301 is made of a material that can be adsorbed by a permanent magnet, so that the clamping component 3 can be easily connected to the bottom of the hanging component 2 to remove the fixed PCB board, and the fitting groove 2 308 and the permanent magnet 213 limit the clamping component 3 to prevent the hanging component 2 from rotating during the forward movement.

[0036] Working principle: first, connect the PCB surface nickel-gold treatment device to the external power supply equipment, start the forward and reverse motor 207 through the external controller, and driven by the output end of the forward and reverse motor 207, the three pulleys 1 203 and the pulley 2 206 rotate accordingly. The staff pulls down the clamping component 3 by hand, and by rotating the top knobs of the two knob bolts 305, the distance between the clamping plate 2 306 and the clamping plate 1 302 increases due to the threaded connection with the knob bolt 305. Then, multiple PCB boards are vertically clamped between the clamping plate 1 302 and the clamping plate 2 306 as needed, and then the knob bolt 305 is rotated in the opposite direction to make the clamping plate 1 The distance between 302 and the second clamping plate 306 is close to fix multiple PCB boards. This design can perform nickel-gold treatment on the surfaces of multiple PCB boards at one time, which improves work efficiency. The fixed clamping component 3 is sucked back to the bottom of the fitting groove 214. When the clamping component 3 moves to the place where the suspension track 1 bends downward, the hanging component 2 follows downward, and the multiple PCB boards are in contact with the solution in the liquid medicine pool 101 for nickel-gold treatment. This design avoids the use of an electric winch to lift the PCB board. The steel wire rope in the electric winch is prone to wear and breakage during frequent lifting, thereby causing damage to the PCB board.
