[0003] In the existing pcba film plating clamp, a planar laminated clamp architecture is adopted, and the clamp structure is generally composed of a clamp bottom plate and a steel sheet; in the film plating process, the product is arranged between the clamp bottom plate and the steel sheet.

[0004] When the clamp of this structure is subjected to furnace plating, the film plating material will deposit on the surface of the product, the steel sheet and the clamp bottom plate, and since the clamp bottom plate and the product, and the product and the steel sheet are closely laminated, the film plating material is easy to form a continuous film layer therebetween. As the film plating thickness increases, the film layer will tightly adhere the product and the steel sheet together.

[0005] The adhesion will generate a large stress, and when the product or the steel sheet attempts to separate from the adhered film layer, the film layer is easy to break due to the brittleness of the film layer (especially some ceramic films or metal oxide films). The fragments generated by the film layer breakage can scratch the surface of the product, causing product damage; at the same time, forcibly separating the product and the steel sheet can also directly damage the structural integrity of the product.

[0006] Therefore, there is an urgent need for a novel clamp dismounting tool to solve the above problems.

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 In an embodiment, a novel clamp dismounting tool includes a positioning base plate 1 and a pressing plate 2, the positioning base plate 1 is provided with a guide 3, the pressing plate 2 is connected with the positioning base plate 1 through the guide 3, the pressing plate 2 is provided with a plurality of product pressing columns 7, the plurality of product pressing columns 7 are used to press the product 13, and the pressing plate 2 is uniformly embedded with magnets 4.

[0030] Specifically, in the embodiment, the clamp comprises a clamp base plate 11 and a steel sheet 12, the clamp is used for placing a product 13, which is specifically a pcba, the clamp base plate 11 is provided with a plurality of placing grooves for placing the pcba, and the steel sheet 12 is provided with a plurality of through holes aligned with the placing grooves; so as to expose the film-coated area of the product 13. In the film-coating process, the product 13 is fixed between the clamp base plate 11 and the steel sheet 12.

[0031] Preferably, on the basis of the above embodiment, the guide 3 is a cylindrical guide column, and the positioning base plate 1 is provided with at least two guide columns.

[0032] Preferably, on the basis of the above embodiment, the pressing plate 2 is provided with a plurality of mounting holes on the side away from the positioning base plate 1, and the plurality of mounting holes are provided with magnets 4.

[0033] Through the above arrangement, in use, the clamp with the product 13 is placed in the positioning base plate 1, and then the pressing plate 2 is connected with the positioning base plate 1 by using the guide 3, so as to ensure that the product pressing column 7 can accurately fit the product 13 in the clamp. After connection, the product pressing column 7 on the pressing plate 2 passes through the through hole of the clamp steel sheet and fits the product 13 in the clamp, which is helpful for pressing the product 13 during disassembly. Then, the upper surface of the pressing plate 2 is tapped or pressed downward by using a tool, at this time, the steel sheet 12 and the product 13 on the clamp are separated, the magnets 4 uniformly arranged on the pressing plate 2 provide a stable upward adsorption force for the steel sheet 12, so that the steel sheet 12 on the clamp can move upward under the action of the magnets 4 and fit the pressing plate 2, so that the steel sheet 12 can be smoothly separated from the product 13, at this time, the product 13 can be smoothly taken off from the positioning base plate 1.

[0034] Preferably, in the embodiment, the clamp is further provided with positioning holes, for example, a plurality of positioning holes are arranged on the clamp base plate 11 and / or the steel sheet 12, when the clamp with the product 13 is placed in the positioning base plate 1, the guide 3 penetrates the positioning holes on the clamp, so as to position the clamp.

[0035] It can be understood that when the clamp is placed in the positioning base plate 1, the pressing plate 2 is connected with the positioning base plate 1 by using the guide column, and this accurate positioning ensures the accurate relative position of each component during the entire disassembly process. For the clamp, the product 13 and the steel sheet 12 after the furnace film coating, the accurate positioning makes the film layer between the product 13 and the steel sheet 12 in an initial state be in a stable state, and does not produce additional stress due to the misalignment between components; for example, if there is no such accurate positioning, even a small displacement deviation in the subsequent operation may cause the film layer to bear uneven force in the local area, increasing the risk of sticking and film layer rupture.

[0036] Further, the product pressing column 7 on the pressing plate 2 is in contact with the product 13 in the clamp, and the contact relationship plays a key role in the tapping process; when tapping the upper surface of the pressing plate 2, the force is uniformly transmitted to the product 13 through the product pressing column 7;

[0037] Further, the tool taps the upper surface of the pressing plate 2, and due to the positioning and contact relationship described above, the tapping force can be transmitted to the clamp and the product 13 in a relatively uniform and controllable manner. The force is sufficient to overcome the weak adhesion between the product 13 and the steel sheet 12, so that they are separated;

[0038] The magnet 4 attracts the steel sheet 12 to the pressing plate 2, so that the steel sheet 12 is away from the product 13, effectively avoiding the possibility of the steel sheet 12 and the product 13 adhering together again in subsequent operations (such as the process of removing the product 13); this ensures that the product 13 can be smoothly removed from the positioning base plate 1 without causing film layer rupture or product 13 damage due to the re-adhesion of the steel sheet 12.

[0039] Specifically, please refer to Figure 4 , Figure 5 On the basis of the above embodiment, the clamp pressing block 6 is further included, and the two ends of the pressing plate 2 are respectively provided with the clamp pressing block 6. Preferably, the size of the clamp base plate 11 is slightly larger than the size of the steel sheet 12, and when the product is installed between the clamp base plate 11 and the steel sheet 12, the two ends of the clamp base plate 11 exceed the edges of the steel sheet 12, and the clamp pressing block 6 is in contact with the left and right ends of the clamp base plate 11 on the side close to the positioning base plate 1. It can be understood that the clamp base plate 11 can be pressed down by setting the clamp pressing block 6.

[0040] Specifically, please refer to Figure 2 On the basis of the above embodiment, the screw hole is further included, and a plurality of screw holes are provided on the pressing plate 2, and the clamp pressing block 6 is connected with the pressing plate 2 through the screw hole. It can be understood that the connection mode of the screw hole and the screw 8 is convenient for disassembly and installation, and different specifications of the clamp pressing block 6 can be replaced to make the use range of the whole disassembly tooling more extensive.

[0041] Specifically, please refer to Figure 2 On the basis of the above embodiment, the jacking column 10 is further included, and a plurality of jacking columns 10 are provided on the positioning base plate 1. It can be understood that the jacking column 10 can be used to support the steel sheet 12 on the clamp, and when the pressing plate 2 is not placed, that is, the product pressing column 7 is not in contact with the product 13, there is a gap between the clamp bottom and the positioning base plate 1, and the jacking column 10 can penetrate the clamp base plate to support the steel sheet.

[0042] Specifically, in the embodiment, a plurality of through holes are arranged on the clamp base plate 11, the plurality of through holes on the clamp base plate 11 correspond to the positions of the top pillars 10 on the positioning base plate 1, the top pillars 10 pass through the through holes on the clamp base plate 11 and contact the steel sheet 12, thereby supporting the steel sheet 12. During the process of pressing the pressing plate 2, the product pressing pillars 7 contact the product, the clamp pressing blocks 6 are attached to the two ends of the clamp base plate, at this time, the top pillars 10 support the steel sheet, the pressing plate 2 is pressed, the product 13 and the clamp base plate 11 move downward relative to the steel sheet 12, thereby separating from the steel sheet 12.

[0043] Specifically, referring to Figure 2 On the basis of the above embodiment, a buffer rubber pad 5 is further included, the positioning base plate is in a rectangular shape, and the four corners of the positioning base plate 1 are respectively provided with the buffer rubber pad 5. It can be understood that, by arranging the buffer rubber pad 5, rigid contact between the clamp and the positioning base plate 1 can be avoided, and the contact surface of the clamp and the positioning base plate can be protected.

[0044] Specifically, referring to Figure 2 On the basis of the above embodiment, a silica gel pad 9 is further included, and the plurality of product pressing pillars 7 are provided with the silica gel pad 9. It can be understood that the force generated by tapping or pressing the pressing plate 2 will directly act on the pcba through the product pressing pillars 7, which may generate a large impact force, causing damage to the electronic components or circuits inside the pcba; and the silica gel pad 9 can disperse and buffer this impact force, reducing the impact force on the pcba.

[0045] In summary, the novel clamp dismounting tool provided by the present application has clear operation steps, from clamp placement, pressing plate 2 connection to pressing the pressing plate and steel sheet 12 adsorption, forming a standardized operation process; the operator can quickly and accurately complete the dismounting work of the pcba according to the process; at the same time, as long as the operation process is operated according to the specified operation process, the dismounting tool with this structure can achieve good dismounting effect every time, that is, the product 13 can be smoothly dismounted, while the integrity of the film layer and the product 13 is ensured.
