[0003] In a vertical electroplating production line for PCBs, fixtures are used to hold the PCBs, while a conveyor drives the fixtures and PCBs to move horizontally. After electroplating, the PCBs are then conveyed to a receiving system. Traditional conveyor systems typically use belts or rollers to transport the fixtures, and the opening and closing of the fixtures requires additional control mechanisms. These systems cannot be integrated with the conveyor system, resulting in complex structures and high manufacturing difficulty. Utility Model Content

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 4 As shown, the PCB board electroplating clamping and conveying device of this utility model includes: a track plate 1, a horizontal track groove 11 corresponding to its outer side is formed on the top periphery of the track plate 1, a horizontal sink 12 is formed in one side of the track groove 11, and a first slope 13 and a second slope 14 are formed at the connection between the sink 12 and the track groove 11; an upper clamp 2, a traveling wheel 4 is provided at the top of the upper clamp 2, and the upper clamp 2 travels in the track groove 11 and the sink 12 of the track plate 1 by means of the traveling wheel 4, and a first clamping part 21 is provided at the bottom of the upper clamp 2; and a lower clamp 3, a second clamping part 31 adapted to the first clamping part 21 is provided at the bottom of the lower clamp 3, and the lower clamp 3 is configured to move synchronously with the upper clamp 2 along the track groove 11.

[0024] See Figures 1 to 3The track plate 1 has an waist-shaped structure. A track groove 11 with the same shape as its outer edge is opened on the top outer periphery of the track plate 1. A recessed groove 12 is opened in the track groove 11. In the height direction, the height of the recessed groove 12 is lower than the height of the track groove 11. A first slope 13 and a second slope 14 are formed at the connection between the recessed groove 12 and the track groove 11. A traveling wheel 4 is rotatably installed on the top side of the upper clamp 2. The traveling wheel 4 has a shape and size that are adapted to the track groove 11 and the recessed groove 12. When the traveling wheel 4 moves in the track groove 11 and the recessed groove 12 of the track plate 1, the upper clamp 2 moves along the track groove 11 with the help of the traveling wheel 4. The bottom end of the upper clamp 2 has a first clamping part 21 for clamping the PCB board. The lower clamp 3 is configured to move synchronously with the upper clamp 2 along the track groove 11. The bottom end of the lower clamp 3 is provided with a second clamping part 31 for clamping the PCB board. The first clamping part 21 and the second clamping part 31 are adapted to each other.

[0025] It should be noted that the position of the track plate 1 is fixed relative to the upper clamp 2 and the lower clamp 3. The lower clamp 3 is provided with an "I"-shaped guide block 32 on the side away from the upper clamp 2. The guide block 32 is slidably installed on the outer frame so that when the lower clamp 3 moves along the track groove 11, the frame can limit the guide block 32, thereby limiting the lower clamp 3 and ensuring the stability of the lower clamp 3 during movement.

[0026] Specifically, during the electroplating of the PCB board, an external drive device drives the lower clamp 3, which in turn drives the upper clamp 2, which moves synchronously along the track groove 11. When the traveling wheel 4 moves within the track groove 11 of the track plate 1, the first clamping part 21 of the upper clamp 2 moves relatively away from the second clamping part 31 of the lower clamp 3, and the first clamping part 21 and the second clamping part 31 are in an open state. At this time, the PCB board is not clamped. When the drive device controls the lower clamp 3 and the upper clamp 2 to move, causing the traveling wheel 4 to descend through the first ramp 13 into the sink 12, the lower clamp 3 moves vertically... The first clamping part 21 moves downwards, bringing it close to the second clamping part 31. At this point, the first clamping part 21 and the second clamping part 31 can clamp and fix the PCB board. As the traveling wheel 4 moves in the sink 12, the PCB board enters the electroplating bath for electroplating. After electroplating, the traveling wheel 4 moves to the second ramp 14 and rises through the second ramp 14 into the track groove 11. At this point, the lower clamp 3 moves vertically upwards, and the first clamping part 21 moves away from the second clamping part 31. The electroplated PCB board is then unloaded, realizing automatic loading and unloading of the PCB board during the electroplating process, improving the electroplating efficiency of the PCB board, and possessing practicality.

[0027] In one or more embodiments, the upper clamp 2 has a first waist hole 22 vertically penetrating through it, and the lower clamp 3 has an elastic member 5 disposed on the side facing the upper clamp 2. A limiting rod connected to the top of the elastic member 5 is disposed in the first waist hole 22. With the help of the elastic force of the elastic member 5, the limiting rod is always pressed against the bottom surface inside the first waist hole 22. The elastic member 5 is a spring or elastic steel.

[0028] See Figure 1 , Figure 4 The limiting rod is pressed down to the bottom surface inside the first waist hole 22 by the elastic element 5, so that the traveling wheel 4 on the top side of the upper clamp 2 can always be pressed against the track groove 11 or the sink 12, thereby achieving the stability of the first clamping part 21 of the upper clamp 2 and the second clamping part 31 of the lower clamp 3 for clamping and fixing the PCB board.

[0029] In one or more embodiments, the limiting rod has a first diameter enlargement portion 6 at one end extending from the first waist hole 22 of the upper clamp 2, and the width of the first diameter enlargement portion 6 is greater than the width of the first waist hole 22. See also Figure 4 By restricting the side of the upper clamp 2 through the first diameter enlargement part 6, the traveling wheel 4 at the top side of the upper clamp 2 can always be restricted within the track groove 11 or the sink 12, thereby improving the stability of the upper clamp 2 and the lower clamp 3 during operation.

[0030] In one or more embodiments, the first diameter enlargement 6 is detachably mounted on the end of the limiting rod. See also Figure 4 The first diameter enlargement 6 can be bolted to the end of the limit rod; this configuration enables the upper clamp 2 to be quickly assembled and disassembled.

[0031] In one or more embodiments, the track groove 11 is provided with at least one set of protrusions 15. See also Figure 1 , Figure 2 In the height direction, the height of the protrusion 15 is greater than the height of the track groove 11. When the traveling wheel 4 passes over the protrusion 15 on the track plate 1, the first clamping part 21 of the upper clamp 2 is further raised relative to the second clamping part 31 of the lower clamp 3. At this time, the first clamping part 21 and the second clamping part 31 can be rinsed by the cleaning device to improve the cleanliness of the first clamping part 21 and the second clamping part 31 and improve the quality of PCB board electroplating in this application.

[0032] In one or more embodiments, both the first clamping part 21 and the second clamping part 31 have an arc-shaped curved structure, so that the first clamping part 21 and the second clamping part 31 clamp the PCB board in a horizontal state. See Figure 4 With this configuration, the PCB board can be held horizontally by the first clamping part 21 of the upper clamp 2 and the second clamping part 31 of the lower clamp 3, thereby improving the stability of PCB board electroplating and handling in this application.

[0033] In one or more embodiments, the first clamping portion 21 of the upper clamp 2 has a first notch 211 through which the electrolyte passes, and the second clamping portion 31 of the lower clamp 3 has a second notch 311 through which the electrolyte passes. See also Figure 1 The first notch 211 on the first clamping part 21 of the upper clamp 2 and the second notch 311 on the second clamping part 31 of the lower clamp 3 enable more electrolyte to flow through the surface of the clamped PCB board, thereby improving the uniformity and efficiency of electroplating on the PCB board surface.

[0034] In one or more embodiments, the upper clamp 2 has a second waist hole 23 vertically opened at the bottom, and the lower clamp 3 has a pad 7 disposed on the side facing the upper clamp 2. The pad 7 extends through the second waist hole 23 to the outer side of the upper clamp 2 on the side away from the lower clamp 3 and forms a second diameter enlarged portion 72. The width of the second diameter enlarged portion 72 is greater than the width of the second waist hole 23.

[0035] See Figure 4 The thickness of the pad 7 is adapted to the gap between the upper clamp 2 and the lower clamp 3. By filling the gap between the bottom of the upper clamp 2 and the bottom of the lower clamp 3 with the pad 7, and by restricting the position of the upper clamp 2 with the second diameter enlargement part 72, the problem of vibration at the bottom of the upper clamp and the lower clamp during the movement of the PCB board can be effectively avoided, thereby improving the electroplating quality of the PCB board in this application.

[0036] In one or more embodiments, the surfaces of the upper clamp 2 and the lower clamp 3 are coated with a polytetrafluoroethylene (PTFE) coating. It should be noted that the PTFE coating possesses certain chemical corrosion resistance and self-lubricating properties, which can improve the service life of the upper clamp 2 and the lower clamp 3, while also reducing the problem of electrolyte adhering to the surfaces of the upper clamp 2 and the lower clamp 3 and being difficult to clean.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
