Description

Technical Field

[0001] The utility model relates to the technical field of electroplating tools, in particular to a clamping claw for electroplating a heat sink. Background Art

[0002] The heat sink is often hung in a plating rack by means of a hook or clamp made of a conductive material (metal or non-metallic material with a conductive layer, etc.), and the plating is completed through the process steps of cleaning, degreasing, electroplating, cleaning, and drying.

[0003] The heat sink is generally mounted on a hanger by means of clamps, but in the prior art the clamps are generally "U"-shaped or "V"-shaped. Due to the particularity of their own deformation, the corners are used to fix the sides of the heat sink. As a result, the contact parts between the heat sink and the clamps will inevitably produce electroplating marks due to the influence of current mapping during electroplating. In addition, the "U"-shaped or "V"-shaped clamps are mostly simple steel wires with relatively smooth surfaces. The actual fixing effect on the heat sink is poor, which inevitably leads to the risk of the heat sink becoming detached in the plating tank due to external forces such as ultrasonic vibration and aeration stirring. Utility Model Content

[0007] The clamping assembly includes a receiving column vertically arranged above the hanging plate and a positioning column fixed to an end of the receiving column away from the hanging plate, and a threaded groove is arranged on the surface of the positioning column;

[0008] The sliding assembly comprises an I-shaped sliding block fixed to the bottom end of the receiving column, and a sliding groove matched with the sliding block is provided on the top surface of the hanging plate, and the cross section of the sliding groove is an inverted T shape.

[0009] Preferably, a first tooth plate is fixed on the side wall of the sliding block above the hanging plate, a second tooth plate corresponding to the first tooth plate is slidably arranged on the top surface of the hanging plate, and an elastic push-pull member is arranged on the side of the second tooth plate away from the first tooth plate.

[0010] Preferably, the elastic push-pull member includes a fixed tube vertically fixed on the top surface of the hanging plate and a pull rod transversely arranged on the inner side of the fixed tube, one end of the pull rod passes through the fixed tube and is fixed to the second tooth plate, and the other end of the pull rod passes through the fixed tube and is fixed with a pull tab.

In addition, the threaded groove is used to increase the friction between the contact part of the heat sink and the positioning column, thereby reducing the risk of the heat sink being detached during the electroplating process to a certain extent.

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-4 As shown, a clamp for electroplating a heat sink comprises a hanger 6, a plurality of L-shaped hanger rods 7 are fixed at equal distances on both sides of the hanger 6, a hanger plate 8 is fixed at the end of the hanger rod 7, and a clamping assembly for hanging the heat sink is arranged on the hanger plate 8;

[0024] There are three groups of clamping components, which are distributed in a triangular shape, and the clamping components include a receiving column 9 vertically arranged above the hanging plate 8 and a positioning column 10 fixed to the end of the receiving column 9 away from the hanging plate 8, and a threaded groove is arranged on the surface of the positioning column 10;

[0025] By setting the clamping assembly, when hanging the heat sink, the heat sink can be directly placed between the three groups of clamping assemblies. The receiving column 9 in the clamping assembly supports the heat sink, and the positioning column 10 fits the side wall of the heat sink, so that the heat sink and the positioning column 10 are in planar contact. Compared with the "U"-shaped or "V"-shaped clamping claws in traditional technology, the contact area of ​​the heat sink is effectively increased, and the surface of the heat sink is prevented from being affected by the electroplating current mapping, which causes electroplating marks to appear. In addition, the threaded groove is used to increase the friction between the contact part of the heat sink and the positioning column 10, which reduces the risk of the heat sink coming off during the electroplating process to a certain extent.

[0026] Further, refer to Figure 3 As shown, it is worth noting that a sliding component is provided between the clamping component and the hanging plate 8;

[0027] The sliding assembly includes a sliding block 12 fixed to the bottom end of the receiving column 9 in an I-shaped shape, and a sliding groove 11 adapted to the sliding block 12 is provided on the top surface of the hanging plate 8, and the cross section of the sliding groove 11 is an inverted T shape;

[0028] By setting the slider 12 and the slide groove 11, the receiving column 9 is pushed and pulled, that is, the slider 12 slides inside the slide groove 11, so that the receiving column 9 and the positioning column 10 can be arbitrarily adjusted as a whole, which is convenient for real-time rapid adjustment of the clamping space between the three groups of clamping components according to the size and model of the heat sink to be electroplated, so that heat sinks of different sizes and models can be hung between the three groups of clamping components, thereby improving the practicality of the device.

[0029] Further, refer to Figure 3 As shown, it is worth noting that a first tooth plate 13 is fixed on the side wall of the slider 12 located above the hanging plate 8, a second tooth plate 14 corresponding to the first tooth plate 13 is slidably arranged on the top surface of the hanging plate 8, and an elastic push-pull member is arranged on the side of the second tooth plate 14 away from the first tooth plate 13;

[0030] The elastic push-pull member includes a fixed tube 15 vertically fixed on the top surface of the hanging plate 8 and a pull rod 16 transversely arranged inside the fixed tube 15. One end of the pull rod 16 passes through the fixed tube 15 and is fixed to the second tooth plate 14. The other end of the pull rod 16 passes through the fixed tube 15 and is fixed to the pull tab 5.

[0031] The pull rod 16 is located on the rod body of the fixed tube 15 and is sleeved with a compression spring 3. One end of the compression spring 3 is fixedly connected to the inner wall of one side of the fixed tube 15. The other end of the compression spring 3 is fixed with a circular ring-shaped pressing plate 4, which is tightly sleeved on the rod body of the pull rod 16.

[0032] By setting the elastic push-pull member, the first tooth plate 13 and the second tooth plate 14, when the receiving column 9 needs to be moved arbitrarily, the pull tab 5 is pulled in advance, so that the second tooth plate 14 is separated from the first tooth plate 13 under the action of the pull rod 16, thereby releasing the fixing effect of the slider 12, and facilitating manual sliding of the slider 12;

[0033] During the process of pulling the pull tab 5, the pull rod 16 carries the pressing plate 4 to slide synchronously inside the fixed tube 15 and compress the clamping spring 3 to deform. In this way, the elastic force of the clamping spring 3 is utilized. After the sliding adjustment of the slider 12 is completed, the pulling of the pull tab 5 is released, and the pressing plate 4 can reset the pull rod 16 under the elastic force of the clamping spring 3, and push the second tooth plate 14 back, so that the second tooth plate 14 is engaged with the first tooth plate 13, and then the slider 12, the receiving column 9 and the positioning column 10 can be effectively fixed.

[0034] Further, refer to Figure 4 As shown, it is worth noting that both sides of the fixed cylinder 15 are provided with a slide rod 2 fixed to the second tooth plate 14, and a slide seat 1 fixed vertically to the top surface of the hanging plate 8 is slidably provided on the rod body of the slide rod 2;

[0035] Through the arrangement of the slide 1 and the slide rod 2, when the pull tab 5 is pulled to slide the second tooth plate 14, the slide rod 2 can slide synchronously with the inner side of the slide 1. In this way, the two cooperate to guide the second tooth plate 14 and ensure the stability of the second tooth plate 14 during movement.
