Detailed Implementation

[0026] The present invention will now be described in conjunction with specific embodiments.

[0027] Example 1, as Figures 1 to 4 As shown, a spring-core type mobile phone motherboard bracket and spring sheet welding positioning fixture includes a fixture base 1 and a fixture pressure plate 2 located on the upper side of the fixture base 1. The upper surface of the fixture base 1 is provided with a product placement area 11, and the fixture base 1 is equipped with a plurality of product positioning posts 3 arranged at intervals in the product placement area 11.

[0028] Among them, such as Figures 1 to 4As shown, the fixture base 1 is equipped with a pivot seat 4 at the rear end of the product placement area 11, and the fixed end of the fixture pressure plate 2 is hinged to the pivot seat 4 via a pivot 5.

[0029] Furthermore, such as Figure 3 As shown, the product placement area 11 of the fixture base 1 has a vertical through hole 12 corresponding to the spring placement position. The through hole 12 is fitted with a movable spring core 6 and a compression spring 7 located at the lower end of the movable spring core 6. The upper end of the movable spring core 6 is the spring core positioning part. A bottom stop 8 is screwed onto the lower opening of the through hole 12 of the fixture base 1. The upper end of the compression spring 7 abuts against the movable spring core 6, and the lower end of the compression spring 7 abuts against the bottom stop 8.

[0030] Furthermore, such as Figures 1 to 4 As shown, the fixture pressure plate 2 is equipped with a number of magnets 91 arranged at intervals, and the fixture base 1 is equipped with iron blocks 92 corresponding to each magnet 91; when the fixture pressure plate 2 is closed, each magnet 91 is magnetically attracted to the corresponding iron block 92.

[0031] It should be noted that the fixture pressure plate 2 has a clearance hole 22 in the middle; when the fixture pressure plate 2 is closed, the clearance hole 22 is aligned with the movable spring core 6.

[0032] The following is a detailed description of the spring-loaded mobile phone motherboard bracket and spring-loaded welding positioning fixture in this embodiment, using the specific working process as an example:

[0033] Step a: Open the fixture pressure plate 2 with the top facing up;

[0034] Step b: Place the spring product 101 on the upper end of the movable spring core 6. The movable spring core 6 positions the spring product 101 through the spring core positioning part at its upper end.

[0035] Step c: After the spring piece product 101 is placed and positioned, the mobile phone motherboard bracket product 100 is placed in the product placement area 11 of the fixture base plate. Several product positioning posts 3 of the product placement area 11 are inserted into the structural holes of the mobile phone motherboard bracket product 100 to position the mobile phone motherboard bracket product 100. At this time, the mobile phone motherboard bracket product 100 presses down on the spring piece product 101.

[0036] Step d: Flip the fixture plate 2 downwards and close it. After the fixture plate 2 is closed, several magnets 91 on the fixture plate 2 are magnetically attracted to the corresponding iron blocks 92 on the fixture base 1. The magnetic force between the magnets 91 and the iron blocks 92 keeps the fixture plate 2 in a closed state. The elastic force of the compression spring 7 causes the movable spring core 6 to push against the spring product 101 upwards, so that the spring product 101 and the mobile phone motherboard bracket product 100 are tightly attached.

[0037] Step e: Welding is performed using welding equipment. The welding gun of the welding equipment passes through the clearance hole 22 of the fixture pressure plate 2 to achieve welding of the spring sheet product 101 and the mobile phone motherboard bracket product 100.

[0038] Step f: After welding is completed, flip the fixture upwards and open the fixture pressure plate 2, and then remove the product placement area 11 of the mobile phone motherboard bracket product 100 charging fixture base 1.

[0039] It should be emphasized that when using the spring-core type mobile phone motherboard bracket and the spring-piece welding positioning fixture of this embodiment to position the mobile phone motherboard bracket product 100 and the spring-piece product 101, the elastic force of the compression spring 7 causes the movable spring core 6 to press upward against the spring-piece product 101, and the fixture pressure plate 2, which is magnetically attracted by the magnet 91 and the iron block 92, presses downward against the mobile phone motherboard bracket product 100. That is, the spring-piece product 101 and the mobile phone motherboard bracket product 100 maintain a stable fit under the bidirectional force of the fixture pressure plate 2 and the movable spring core 6, thereby effectively ensuring the welding quality.

[0040] In summary, the above structural design of the spring-core mobile phone motherboard bracket and spring-piece welding positioning fixture in this embodiment has the advantages of novel structural design, good stability and reliability, and can effectively improve welding quality.

[0042] The fixture base 1 has iron block mounting holes 13 for each iron block 92, and each iron block 92 is embedded and fixed in the corresponding iron block mounting hole 13.

[0043] Example 3, as Figure 3 As shown, the difference between this embodiment 3 and embodiment 1 is that: the inner wall of the base through hole 12 is provided with a base shoulder 14, and the movable spring core 6 is provided with a spring core shoulder 61 located on the lower side of the base shoulder 14. The base shoulder 14 and the spring core shoulder 61 are arranged vertically opposite each other.

[0044] When the fixture pressure plate 2 is opened, the spring core shoulder 61 abuts against and is limited to the base shoulder 14; by the cooperation between the spring core shoulder 61 and the base shoulder 14, the spring core type mobile phone motherboard bracket and spring piece welding positioning fixture of this embodiment can effectively prevent the movable spring core 6 from falling out of the base through hole 12.

[0045] Example 4, as Figure 3As shown, the difference between this embodiment four and embodiment one is that the movable spring core 6 has a downward-facing spring positioning hole 62 corresponding to the compression spring 7, and the upper end of the compression spring 7 is embedded in the spring positioning hole 62 of the movable spring core 6.

[0046] The compression spring 7 is positioned by the spring positioning hole 62 of the movable spring core 6. This structural design can effectively ensure the positional stability of the compression spring 7 during use.

[0047] Example 5, as Figures 1 to 4 As shown, the difference between this embodiment seven and embodiment one is that the fixture pressure plate 2 is screwed with a lifting handle 23.

[0048] As for the lifting handle 23 in this embodiment, it can facilitate the operator to flip the operating fixture pressure plate 2, thereby improving the convenience of operation and use.
