Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture for circuit boards and LED lights. Background Technology

[0002] Currently, the soldering process between circuit boards and LED lights typically requires manual positioning or simple tooling. Manual positioning is not only inefficient but also susceptible to operator skill levels and fatigue, making it difficult to guarantee consistent positioning accuracy and prone to soldering misalignment, thus reducing product yield.

[0003] While some existing welding fixtures can assist in positioning to a certain extent, they generally suffer from complex structures and high costs. Some fixtures can only position one of the circuit board or LED light, while the other is still prone to displacement during welding, making it impossible to ensure the stability of their relative positions. Other fixtures have unreasonable positioning structure designs, poor compatibility with circuit boards and LED lights, and may damage components during clamping. They also make it difficult to pick up and put down parts, affecting welding efficiency.

[0004] Therefore, how to provide a simple, low-cost welding fixture that can accurately position circuit boards and LEDs to improve welding accuracy and efficiency and reduce production costs has become an urgent problem for those skilled in the art. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0028] This utility model provides a welding fixture for circuit boards and LED lights.

[0029] In this embodiment, refer to Figure 1-2The circuit board and LED lamp welding fixture includes a base plate 1, a pressure plate assembly, a welding socket 2, and a clamping assembly;

[0030] A cylinder plate 3 is fixed to one side of the base plate;

[0031] The pressure plate assembly includes a pressure cylinder 4 and a pressure plate 5 connected to the output end of the pressure cylinder 4. The pressure plate 5 includes a vertical plate 6 connected to the output end of the pressure cylinder and a horizontal plate 7 for pressing the circuit board. The horizontal plate 7 is provided with a pressure groove 8 adapted to the thickness of the circuit board, and an elastic plate is provided in the pressure groove 8.

[0032] The welding socket is fixed on the base plate on one side of the output end of the clamping cylinder. The welding socket is provided with a deep groove 9 for picking up parts on one side of the clamping cylinder and a lamp groove 11 for placing LED lights 10 on the other side. Positioning grooves 13 for accommodating circuit boards 12 are provided above the steps on both sides of the deep groove 9.

[0033] The clamping assembly is used to clamp the LED light placed in the light slot.

[0034] In the above technical solution, the welding fixture consists of a base plate, a pressure plate assembly, a welding socket, and a clamping assembly. The base plate provides the mounting foundation for each component, and a cylinder plate on one side is used to fix the clamping cylinder of the pressure plate assembly. In the pressure plate assembly, the clamping cylinder drives the pressure plate to move. A vertical plate connects the clamping cylinder and the horizontal plate, and the pressure groove of the horizontal plate is adapted to the thickness of the circuit board. An internal elastic plate can buffer the pressure. The welding socket is fixed on the base plate. The deep groove for picking up components facilitates the placement and removal of the circuit board, the light slot holds the LED light, and the positioning slot accommodates the circuit board for initial positioning. The clamping assembly then clamps the LED light in the light slot. All components work together, constraining the position of the circuit board and the LED light through the positioning slot, light slot, and pressure slot, respectively. The multi-positioning structure achieves precise positioning of the relative position of the circuit board and the LED light, ensuring stable relative position during welding, significantly reducing welding defects caused by misalignment, and improving welding quality. The overall structure is simple, requiring no complex precision components, reducing manufacturing costs, and the operation process is simple, which helps to improve welding efficiency.

[0035] Specifically, the clamping assembly includes a hinge seat 14, a lamp plate 16 connected to the hinge seat via a hinge 15, and a magnetic rubber pad 17 disposed at the bottom of the lamp plate 16, wherein the magnetic rubber pad 17 is magnetically attracted to the welding seat.

[0036] In this embodiment, the clamping assembly is connected to the solder pad via a hinge. The hinge allows the lamp plate to rotate around the hinge, enabling the covering and loosening of the LED lights within the lamp slot. The magnetic rubber pad at the bottom of the lamp plate uses magnetism to attract the solder pad, generating continuous pressure to press the LED lights firmly into the lamp slot. The magnetic attraction method facilitates quick operation, and the rubber material increases friction and prevents hard contact from damaging the LED lights.

[0037] Specifically, the elastic plate includes a spring 18 and a rubber plate 19. A spring hole 20 is provided on the bottom wall of the pressure groove. One end of the spring is fixedly connected to the bottom wall of the spring hole, and the other end is connected to the rubber plate.

[0038] In this embodiment, the elastic plate consists of a spring and a rubber plate. The spring is installed in a spring hole in the bottom wall of the pressure groove, and the rubber plate covers the spring. When the pressure plate presses the circuit board, the spring is compressed and generates elastic force, which is transmitted to the circuit board through the rubber plate. The elastic deformation of the spring absorbs pressure fluctuations. The rubber plate is in direct contact with the circuit board, increasing the force-bearing area and preventing scratches. The elastic buffering effect reduces the impact force during the pressing process, protects the components on the circuit board, and improves the versatility and protective performance of the tooling.

[0039] Specifically, the output end of the clamping cylinder is connected to the pressure plate via a guide rod 21, and a guide base 22 is fixed on the base plate. The guide rod slides in conjunction with the guide hole on the guide base.

[0040] In this embodiment, the output end of the clamping cylinder is connected to the pressure plate via a guide rod. The guide rod passes through the guide hole of the guide base on the base plate and slides with it. When the clamping cylinder drives the pressure plate to move, the guide rod slides axially along the guide hole, restricting the movement trajectory of the pressure plate and ensuring that it only moves in a direction perpendicular to the circuit board, avoiding lateral deviation. This ensures that the pressure groove can accurately align with the circuit board and apply vertical pressure, further improving positioning accuracy.

[0041] Specifically, a buffer spring 23 is fitted onto the guide rod between the guide base and the vertical plate.

[0042] In this embodiment, a buffer spring is sleeved on the guide rod and located between the guide base and the vertical plate. When the pressing cylinder drives the pressure plate downward to press the circuit board, the vertical plate approaches the guide base, and the buffer spring is compressed, using the elastic deformation of the spring to absorb part of the impact force; when the cylinder resets, the spring force assists the pressure plate to quickly return to its original position.

[0043] Specifically, the base plate is provided with mounting lugs 24 on its outer periphery, and mounting lugs 24 are provided with mounting holes 25.

[0044] In this embodiment, mounting lugs on the outer periphery of the base plate are provided with mounting holes, allowing the base plate to be fixed to the workbench or production line using bolts or other fasteners. The mounting lugs increase the connection points between the base plate and the mounting surface, ensuring a secure connection between the fixture and the external structure and preventing displacement of the fixture itself during welding.

[0045] Specifically, the base plate is provided with a storage box 26, which is divided into multiple storage spaces 29 by a horizontal partition 27 and a vertical partition 28. The shape of the storage space is at least compatible with the circuit board.

[0046] In this embodiment, the storage box on the base plate is divided into multiple storage spaces by horizontal and vertical partitions, with the space dimensions adapted to components such as circuit boards. Operators can classify and place circuit boards to be soldered or already soldered into different storage spaces, achieving orderly storage and management of components.

[0047] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
