[0005] When the device clamps the circuit board, the clamps need to be opened in sequence to clamp the two ends of the circuit board. Since the clamps are arranged horizontally side by side, it is also necessary to pay attention to the circuit board as much as possible when clamping the circuit board to avoid partial overlap of adjacent circuit boards after skewing, which affects the electroplating effect; and this clamping method makes the circuit board loading not fast enough. Utility Model Content

[0006] The utility model aims to provide a printed circuit board electroplating fixture to solve the problem that the prior art circuit board electroplating fixture mentioned in the background technology clamps the two ends of the circuit board in sequence, which makes the circuit board loading in the electroplating fixture not fast enough.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model provides a non-metallic immersion rack. When the limit of the outermost clamping plate is released, the clamping plate is manually pulled. Under the action of the connecting rope, the clamping plates can be opened in sequence, so that the distance between adjacent clamping plates is increased, which makes it convenient to put the circuit board on the base between the adjacent clamping plates.

This structure increases the gap between the clamping plates when the circuit board is loaded, so that the circuit board is loaded quickly. When the circuit board is manually pushed into the rack, it is automatically clamped, which can improve the efficiency of loading the circuit board into the electroplating fixture.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5The utility model provides a technical solution: a printed circuit board electroplating fixture, comprising an immersion rack 1, the immersion rack 1 is arranged in a rectangular frame shape, one side of the immersion rack 1 is open, an extended edge 2 and a guide rod 3 are fixed to the open side of the immersion rack 1, a plurality of clamps 4 are arranged in the immersion rack 1, a slide rail 5 is fixed to the upper surface of the extended edge 2, the bottom end of the clamp 4 is slidably connected to the slide rail 5, the guide rod 3 passes through the top of the clamp 4 and is slidably connected to the clamp 4, a base 6 for placing a circuit board is arranged between adjacent clamps 4, a spring 7 is fixed to one side of the base 6 and one side of one of the clamps 4, and a limiting structure 8 is provided on the top and bottom of the immersion rack 1 for limiting the position of the clamp 4 after it is squeezed into the immersion rack 1.

[0024] A tie rope 9 is fixed between adjacent clamps 4. The clamps 4 are arranged in a rectangular frame shape. The tie ropes 9 are respectively fixed on both sides of the clamps 4. By setting the tie rope 9, when the outermost clamps 4 are pulled, the clamps 4 in the immersion rack 1 are pulled out in sequence, and the tie ropes 9 between adjacent clamps 4 are set to be the same in length. After the clamps 4 are pulled apart, it is convenient to fill in the circuit board.

[0025] The base 6 is rectangular, and a groove 10 is provided on the upper surface of the base 6 for placing the bottom end of the circuit board. The two ends of the base 6 are respectively slidably connected with the two slide rails 5. By providing the groove 10, since the distance between the two clamping plates 4 increases after being pulled apart, when the circuit board is placed in the groove 10, the circuit board is placed in a state of tilting to the left, with the bottom end of the circuit board against the groove 10 and the top end of the circuit board against the convex edge 11. This is until circuit boards are placed between all adjacent clamping plates 4.

[0026] An integrally formed convex edge 11 is disposed on one side of the top of the clamping plate 4 , and the convex edge 11 is located above the groove 10 .

[0027] The limiting structure 8 includes a rotating block 801 , which is rotatably connected to the open side of the immersion rack 1 , and a positioning hole 802 is formed at one end of the rotating block 801 .

[0028] The limiting structure 8 also includes a positioning pin 803. A fixing block 804 is welded to the top of the immersion rack 1. The positioning pin 803 passes through one side of the fixing block 804 and is threadedly connected to the fixing block 804. One end of the positioning pin 803 is plugged into the positioning hole 802. After rotating the rotating block 801, the positioning pin 803 is used to pass through the positioning hole 802, and the positioning pin 803 is screwed into the fixing block 804 to fix the rotating block 801. At this time, one end of the rotating block 801 is fixed to the fixing block 804, and the other end is located on the outer wall of the outermost clamping plate 4, so that the clamping plate 4 is limited in the immersion rack 1.

[0029] The top of the immersion rack 1 is riveted with a connecting rod 13, and four groups of the connecting rods 13 are provided, and the four connecting rods 13 are respectively provided at the four corners of the immersion rack 1. By providing the connecting rods 13, it is convenient to fix the immersion rack 1 to the external lifting equipment.

[0030] When in use, the rightmost clamping plate 4 is pulled open, so that the clamping plates 4 are opened at equal intervals under the action of the traction rope, and the base 6 pops up to the right under the elastic action of the spring 7. Since the distance between the two clamping plates 4 increases after being pulled apart, when the circuit board is placed in the groove 10, the circuit board is placed in a state of tilting to the left, with the bottom of the circuit board against the groove 10 and the top of the circuit board against the convex edge 11. Until there are circuit boards placed between all adjacent clamping plates 4, the outermost clamping plate 4 is manually pushed into the rack, and the circuit board is forced to stand vertically while the distance between the clamping plates 4 is reduced, such as Figure 4 As shown, until the outermost splint 4 is completely pushed into the immersion rack 1, manually rotate the rotating block 801, pass the positioning pin 803 through the positioning hole 802, and screw the positioning pin 803 into the fixed block 804 to fix the rotating block 801. At this time, one end of the rotating block 801 is fixed to the fixed block 804, and the other end is located on the outer wall of the outermost splint 4, limiting the splint 4 in the immersion rack 1.

[0031] The whole device only needs to manually open the clamping plate 4, put the circuit boards in order, push the clamping plate 4 into the immersion rack 1, rotate the rotating block 801, and screw in the positioning pin 803. The placement and positioning of the circuit board are faster, which can improve the efficiency of loading the circuit board into the electroplating fixture.
