Description

Technical Field

[0001] This utility model relates to the field of PCBA welding technology, and in particular to a PCBA hand soldering flipping fixture. Background Technology

[0002] Traditional PCBA hand soldering fixtures consist of a single base plate designed according to the product layout and the position and height of the components to be soldered. After manual component insertion, the base plate is flipped upside down to align the inserted components with the product, and then the fixture base plate is flipped over and placed on the soldering table for soldering. This process is not only difficult to align and cumbersome, but also makes it impossible to check the status of the components inside the fixture, affecting the quality of the soldered product (e.g., floating, misalignment, etc.). Current technology involves manually placing the product to be soldered into the fixture in reverse, but this also makes it impossible to check the status of the components inside the fixture. After soldering, the components must be removed for inspection. If misalignment, floating, or other defects are found, manual rework is required, easily leading to quality abnormalities. Furthermore, the difficult alignment process when placing the product into the fixture is cumbersome and affects soldering efficiency. Utility Model Content

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "provided with" should be interpreted broadly. For example, the object "provided with" can be a part of the main body, or it can be separately arranged from the main body and connected to it. This connection can be detachable or non-detachable. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Specific embodiments of the PCBA hand soldering flipping fixture provided by this utility model: Please see Figure 1-7 The PCBA hand soldering flipping fixture includes a base 1, a base plate 2 hinged to the upper side of the base 1, and a transparent pressure cover 3 hinged to the upper side of the base plate 2.

[0025] The base 1 is a square plate structure, and hard rubber pads 14 are provided on the lower side of each of the four corners of the base 1.

[0026] The base support 1 has two first hinge seats 10 on its upper side to support the rotation of the base plate 2. The base plate 2 has two symmetrical rotating shafts on one side of each side that are respectively rotatably engaged with the two first hinge seats 10. The base support 1 also has a first upright plate 11 on its upper side to support the base plate 2. The first upright plate 11 is supported on the end of the base plate 2 away from its hinge end. When the base support 1 is placed horizontally on the welding table, the first hinge seats 10 and the first upright plate 11 support the base plate 2, keeping the base plate 2 in a horizontal state.

[0027] The upper side of the base plate 2 is provided with a second hinge seat 12 to support the rotation of the transparent cover 3. The second hinge seat 12 is hinged to the transparent cover 3 through two hinges. The transparent cover 3 is made of acrylic sheet. The upper side of the base plate 2 is provided with a second upright plate 13 to support the transparent cover 3. The second upright plate 13 is supported at the end of the transparent cover 3 away from its hinge end. When the second hinge seat 12 and the second upright plate 13 support the transparent cover 3, the transparent cover 3 is parallel to the base plate 2.

[0028] The base plate 2 can be flipped together with the transparent cover 3. The upper side of the base support 1 is provided with a slanted support plate 9 that provides inclined support for the transparent cover 3. Flipping the base plate 2 and the transparent cover 3 allows the transparent cover 3 to be supported on the slanted support plate 9, enabling flipping and tilting, which facilitates welding.

[0029] In this embodiment, the first hinge seat 10, the first upright plate 11, and the diagonal brace plate 9 are all bolted to the base support 1. The base support 1 has stepped holes for the bolts to pass through, and the lower ends of the first hinge seat 10, the first upright plate 11, and the diagonal brace plate 9 are all provided with internal threaded holes that mate with the bolts. The bolted diagonal brace plate 9 can be replaced. By replacing the diagonal brace plate 9 with one of different heights, the tilt angle of the base plate 2 and the transparent cover 3 after flipping can be changed, improving applicability and facilitating welding.

[0030] The end of the transparent cover 3 away from the hinge is magnetically connected to the upper side of the base plate 2. Specifically, the upper side of the second upright plate 13 is provided with several iron blocks 8, and the lower side of the end of the transparent cover 3 away from the hinge is provided with several magnetic blocks 7 corresponding to the iron blocks 8. The magnetic blocks 7 are magnetically attracted to the iron blocks 8, so that the transparent cover 3 can be stably pressed on the upper side of the second upright plate 13.

[0031] The base plate 2 has a positioning groove 4 on the upper side for placing PCBA boards. Placing the PCBA board in the positioning groove 4 stabilizes the PCBA board during the soldering process. The positioning groove 4 has a cutout 5, which corresponds to the soldering position of the PCBA board and the back of the soldering parts. After flipping, it can be soldered.

[0032] The transparent pressure cover 3 is provided with several fixed-point pressure posts 6, which limit the positioning of each welded part. Each fixed-point pressure post 6 includes a pressure point screw 61 passing through the transparent pressure cover 3. The transparent pressure cover 3 has a through hole for the pressure point screw 61 to pass through. The head of the pressure point screw 61 is located on the upper side of the transparent pressure cover 3. The lower end of the pressure point screw 61 is threadedly connected to a pressure block 62, which is made of hard plastic. A spring 63 is provided on the outer side of the pressure block 62 and the pressure point screw 61 on the lower side of the transparent pressure cover 3. The two ends of the spring 63 abut against the transparent pressure cover 3 and the pressure block 62 respectively, allowing the welded parts to be elastically pressed, accommodating welded parts of different heights. The pressure block 62 includes an integrally connected square column section and a disc section. The square column section is connected to the pressure point screw 61 for easy rotation and removal. The pressure block 62 and the disc section directly contact the welded parts to achieve positioning. In some embodiments, pressure blocks 62 of different sizes are provided, with different lengths of the square column section to accommodate welded parts of different heights, improving applicability.

[0033] Welding process: Open the transparent cover 3, place the PCBA board in the positioning groove 4, place the welding parts on the PCBA board, press down the transparent cover 3, and use magnetic connection to make the fixed point pressure column 6 press the welding parts tightly. Flip the base plate 2 so that the inclined support plate 9 supports the transparent cover 3. The bottom surface of the PCBA is tilted upward, and the cutout 5 exposes the welding parts for welding work.

[0034] The auxiliary part of the base support 1 in this utility model is designed according to the size of the base plate 2 and the welding angle to ensure the convenience of welding. The positioning groove 4 of the base plate 2 is hollowed out according to the size of the PCBA board and the position of the back parts and welding parts to prevent the product from being unable to be placed or to hinder welding. The transparent pressure cover 3 fixes the parts point-to-point according to the height and shape of the hand-welded plug-in parts to prevent abnormalities such as part skewing and floating. This not only ensures the quality of the product, but also improves the production efficiency by more than double, and the yield rate is increased to 100%.

[0035] This invention makes welding smoother and the weld points smoother and stronger. The transparent cap 3 is connected by a hinge on one side and magnetically on the other, reducing the time and effort required to pick up and put down the transparent cap 3. It can be directly inserted into the tooling, reducing the time and effort required for product and tooling assembly.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
