Description

Technical Field

[0001] This utility model relates to the field of electronic product manufacturing, specifically to a semi-automatic tooling for bonding spring wires. Background Technology

[0002] Currently, in the production process of electronic product switching power supplies, due to the irregular shape of the spring contacts and the fact that there are two types of spring contacts (left and right), and welding operations need to be performed on the spring contacts, it is necessary to use the left and right hands to hold the soldering iron to weld different spring contacts. This welding operation is difficult, inefficient, and produces poor quality. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a semi-automatic tooling for spring wire bonding.

[0004] The technical solution of this utility model is as follows:

[0005] A semi-automatic tooling for spring-loaded wire bonding includes a base plate and a spring-loaded heating fixture, a control board, and a switching power supply mounted on the base plate. The spring-loaded heating fixture includes a base, a support, a limiting plate, and a heating plate. A switch is provided on the front side of the base. The support is mounted on the base and forms a limiting slot with the base. The heating plate is elastically mounted in the limiting slot. The limiting plate is mounted on the support, and a spring-loaded receiving slot is formed between the limiting plate and the heating plate.

[0006] Furthermore, the heating plate is equipped with a PTC heating block and a temperature controller.

[0007] Furthermore, the base is provided with a first spring post and a second spring post at both ends, and the heating plate is disposed on the first spring post and the second spring post.

[0008] Furthermore, an electromagnet is provided on the base, and a magnet is provided on the bottom of the heating plate corresponding to the electromagnet.

[0009] Furthermore, the control board is mounted on the base plate via a control board mounting bracket.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, it is only necessary to place the spring in the spring receiving slot and heat the spring by the heating plate. The operator does not need to operate the soldering iron. He can add solder with one hand and release wire with the other hand to perform wire bonding operation on the spring. This solves the problem of the inconvenience of the operator's left and right hands operating tools, greatly improves the welding efficiency, and ensures the quality of wire bonding.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0016] Example

[0017] Please see Figure 1 This embodiment provides a semi-automatic tooling for spring-loaded wire bonding, including a base plate 1 and a spring-loaded heating fixture 2, a control board 3, and a switching power supply 4 mounted on the base plate 1. The control board 3 is mounted on the base plate 1 via a control board mounting bracket 5. The spring-loaded heating fixture 2 includes a base 21, a support 22, a limiting plate 23, and a heating plate 24. A switch 25 is provided on the front side of the base 21. The support 22 is mounted on the base 21 and forms a limiting slot with the base 21. A first spring post 6 and a second spring post 7 are respectively provided at both ends of the base 21. The heating plate 24 is mounted on the first spring post 6 and the second spring post 7 and is elastically located in the limiting slot. An electromagnet 8 is provided on the base 21. Figure 2 As shown, a magnet 241 is provided at the bottom of the heating plate 24 corresponding to the electromagnet 8. A PTC heating block 242 and a temperature controller 243 are provided in the heating plate 24. A limiting plate 23 is provided on the support 21. A spring receiving slot is formed between the limiting plate 23 and the heating plate 24.

[0018] The operation process is as follows:

[0019] 1. Connect the power supply;

[0020] 2. Set the corresponding temperature using the buttons on control panel 3;

[0021] 3. Place the spring clip 10 to be welded into the spring clip receiving slot;

[0022] 4. Heat the spring 10 with the heating plate 24. After heating is complete, place the solder wire at the soldering point of the spring to add solder.

[0023] 5. After all the spring contacts have been tinned, the operator only needs to put the wires into the tin contacts and then remove the spring contact 10.

[0024] 6. After the work is completed, turn on switch 25, and electromagnet 8 will be attracted to press down heating plate 24 so that spring sheet 10 can be added next time.

[0025] This semi-automatic tooling for bonding springs eliminates the need for operators to use a soldering iron. They can simply add solder with one hand and release wire with the other to bond the springs, solving the problem of inconvenience for operators who cannot use tools with both hands. This greatly improves welding efficiency while ensuring the quality of the wire bonding.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
