Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and particularly relates to a wave soldering fixture for a collection terminal type. Background Art

[0002] In the wave soldering process, the PCB board needs to be infiltrated by high-temperature solder (usually 260 - 300 °C) to achieve reliable connection between the component pins and the pads. As an important tool for supporting and protecting the PCB board, in order to ensure the welding quality, the wave soldering fixture not only needs to have good high-temperature resistance, but also needs to maintain structural stability in the high-temperature environment to prevent the PCB board from deforming or having poor soldering.

[0003] In the prior art, the wave soldering fixture in the PCBA production section of collection terminal type products is long-term exposed to the high-temperature environment. Affected by thermal stress, it is easy to cause material fatigue and structural deformation of the fixture. Especially at the part where the fixture contacts the track chain claw, due to the mechanical friction force exerted by the chain claw on the fixture during the transmission process, frequent friction with the bottom of the fixture, and the dual action of the high-temperature environment, the bottom of the fixture is prone to wear, deformation or even fracture. This will not only reduce the durability of the fixture, but also cause the support flatness of the PCB board to decline, and then lead to problems such as poor soldering, such as virtual soldering, bridging or solder joint offset, and even cause PCB positioning offset. In addition, the deformation of the fixture will increase the residue of the flux on the surface of the fixture, further affecting the welding quality and production efficiency.

[0004] Therefore, it is urgently needed to design a wave soldering fixture for a collection terminal type that can effectively disperse the friction stress of the chain claw on the fixture and prevent the bottom of the fixture from deforming. Summary of the Utility Model

The strength of the contact member 12 is not less than the strength of the fixture body 11.

By setting the contact member 12 to be connected to the transmission surface of the fixture body 11 and making the contact member 12 contact with the track chain claw of the solder wave furnace, the transmission of the wave soldering fixture 1 for the acquisition terminal in the solder wave furnace is realized, and the strength of the contact member 12 is not less than that of the fixture body 11, which can effectively disperse the thermal stress of the wave soldering fixture 1 for the acquisition terminal in the high-temperature environment of the solder wave furnace and the mechanical friction stress of the track chain claw, effectively solving the problem in the prior art that the bottom of the fixture is easily worn, deformed or even fractured due to the friction stress of the track chain claw on the fixture, thereby avoiding the problem of poor soldering caused by the deformation of the fixture.

[0045] Further, the number of the contact members 12 is two, and the two contact members 12 are respectively connected to both ends of the transmission surface.

[0046] Specifically, the two contact members 12 are respectively connected to both ends of the transmission surface, which not only reduces the material cost of the contact members 12, but also helps to disperse the friction stress of the chain claw on the fixture, ensures the support flatness of the PCB board 2, prevents the PCB board 2 from deforming and bending, improves the soldering accuracy, and reduces the risk of poor soldering.

[0047] Specifically, in the embodiment of the present invention, the sizes of the two contact members 12 are both 400mm * 20mm * 3mm, but this should not be used as a limitation of the embodiment of the present invention.

[0050] Further, the wave soldering fixture 1 for the acquisition terminal further includes a connecting member 1212.

[0053] Specifically, the contact piece 12 is detachably connected to the transmission surface, which is convenient for replacing the damaged contact piece 12, reduces the maintenance cost, improves the flexibility of the fixture, and enables the new contact piece 12 to be quickly replaced when the contact piece 12 is worn or damaged without affecting the use of the entire wave soldering fixture 1 of the acquisition terminal type.

[0054] Furthermore, a sealing coating is provided at the connection between the contact piece 12 and the transmission surface, and the sealing coating is used to prevent the solder flux from penetrating into the connection.

[0055] Specifically, a sealing coating is arranged at the connection between the contact piece 12 and the transmission surface to prevent the solder flux from penetrating into the connection, effectively blocking the penetration of the solder flux, avoiding the welding quality problems caused by the residual solder flux, and further prolonging the service life of the wave soldering fixture 1 of the acquisition terminal type.

[0056] Specifically, the contact piece 12 is of a metal structure. Setting the contact piece as a metal structure with high temperature resistance and high strength can ensure the structural stability and strength of the contact piece 12 in the high-temperature environment inside the solder bath, reducing the deformation and damage of the contact piece 12 caused by high temperature and mechanical stress.

[0057] Furthermore, the contact piece 12 is of a flat structure and is flush with the bearing surface 111 of the fixture body 11.

[0058] Specifically, the contact piece 12 is of a flat and smooth structure and is flush with the bearing surface 111 of the fixture body 11, which not only helps to ensure the stable transmission of the PCB board 2 during the welding process, but also helps to reduce the residue of the solder flux on the surface of the fixture. In addition, the contact piece 12 with a flat and smooth structure also helps to reduce the frictional resistance with the track chain claws, improving the welding quality and production efficiency.

[0059] Furthermore, the wave soldering fixture 1 of the acquisition terminal type further includes a heat dissipation part, and the heat dissipation part is connected to the transmission surface and is used to conduct the heat of the fixture body 11 to the air.

[0060] Specifically, the heat dissipation part is connected to the transmission surface and is used to conduct the heat of the fixture body 11 to the air, which helps to reduce the temperature of the fixture body 11, reduce the material fatigue and deformation caused by high temperature, and at the same time improve the heat dissipation efficiency of the wave soldering fixture 1 of the acquisition terminal type and prolong its service life.

[0061] More specifically, in the embodiment of the present utility model, the heat dissipation member is the contact member 12. It can be understood that the contact member 12 has a heat dissipation function and can conduct the heat of the fixture body 11 to the air.

The protection block 112 is arranged at the edge of the hollow opening 113 and is connected to the transmission surface.

[0063] Specifically, a hollow opening 113 is provided on the fixture body 11, and a protection block 112 is arranged at the edge of the hollow opening 113. The hollow opening 113 exposes the solder joints of the PCB board 2, facilitating the soldering operation; the protection block 112 can prevent the molten tin from damaging the fixture body 11 at the edge of the hollow opening 113 during the soldering process, improving the quality and safety of soldering.

[0064] More specifically, the hollow opening 113 and the protection block 112 vary according to the solder joints of the PCB board 2. Figure 3 The hollow opening 113 shown in

[0065] is for illustration purposes only and should not be construed as a limitation of the present utility model.
