Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a clamp used for PCB board welding. Background Art

[0002] PCB board is a printed circuit board, also known as printed circuit board, printed circuit board, which is an important electronic component, the support body of electronic components, and the provider of electrical connections for electronic components. During the production and processing of PCB boards, they need to be welded. In order to ensure the stability of the PCB board during welding, a PCB board welding device is required.

[0050] like Figure 1 Shown is a schematic diagram of a fixture for PCB board welding according to an embodiment of the present utility model ( Figure 1 The left side is a state diagram of the sliding component not installed on the base, so as to facilitate the observation of the slide groove and slider. The actual installation effect diagram can be combined with Figure 2 Comparative observation). Figure 1 The fixture may include a base 1, a sliding assembly 2, a push-pull assembly 3, and a stopper assembly 4. The sliding assembly 2 may be disposed on the base 1 and slidably connected thereto, and there may be multiple sliding assemblies 2. The push-pull assembly 3 may be disposed on the base 1 and connected to the sliding assembly 2, driving the sliding assembly 2 to slide on the base 1. The stopper assembly 4 may be disposed on the sliding assembly 2 to position and stop the PCB.

[0051] In order to enable the sliding assembly 2 to slide on the base 1 , in one embodiment of the present invention, a sliding groove 10 may be provided on the base 1 of the clamp.

[0052] In this embodiment, the form of the sliding assembly 2 can be various known to those skilled in the art. In a preferred example of the present invention, the sliding assembly 2 can include a slider 20, a bottom plate 21, a side plate 22 and a top plate 23, such as Figure 2 As shown, the slider 20 can be disposed within the chute 10 for sliding within the chute 10. The bottom of the bottom plate 21 is fixedly connected to the slider 20. The side plates 22 can be disposed at both ends of the bottom plate 21 in the direction of the chute 10 and fixedly connected to the bottom plate 21. The top plate 23 can be disposed above the bottom plate 21 and fixedly connected to the side plates 22. The top plate 23 is provided with an elongated opening 230.

[0053] In this embodiment, the push-pull assembly 3 can be in various forms known to those skilled in the art. In a preferred embodiment of the present invention, the push-pull assembly 3 can include a fixed upright plate 30 and an electric telescopic rod 31. The fixed upright plate 30 can be mounted on a side of the base 1, and the electric telescopic rod 31 can be mounted on the fixed upright plate 30, with the end of the electric telescopic rod 31 connected to the side plate 22. The electric telescopic rod 31 extends and retracts in the same direction as the chute 10, and is used to extend and retract to drive the sliding assembly 2 to slide on the base 1.

[0054] In this embodiment, the form of the limiting assembly 4 can be various known to those skilled in the art. In a preferred example of the present invention, the limiting assembly 4 can include a fixed plate 40, a motor 41, a screw 42, a moving plate 43, a moving slider 44 and a movable plate 45, such as Figure 3 As shown. Among them, the fixed plate 40 can be arranged on the other side of the top plate 23 relative to the side plate 22 and fixedly connected to the top plate 23. The motor 41 can be arranged on the fixed plate 40, and the screw rod 42 can be connected to the drive shaft of the motor 41. The surface of the screw rod 42 is provided with a thread, and the direction of the screw rod 42 is the same as the length direction of the elongated opening 230. A threaded hole can be provided on the movable plate 43 for passing the screw rod 42. The movable slider 44 can be connected to the movable plate 43 for passing through the elongated opening 230 and sliding in the elongated opening 230. The movable plate 45 can be arranged above the top plate 23 and connected to the movable slider 44.

[0055] In this embodiment, the number of the elongated openings 230 and the movable sliders 44 can be any number known to those skilled in the art. However, considering that it is difficult to maintain a consistent movement trajectory of the movable plate 45 with a single elongated opening 230 and movable slider 44, in a preferred embodiment of the present invention, the number of the elongated openings 230 and movable sliders 44 can be two, and the two movable sliders 44 are connected to the two ends of the movable plate 43 and the two ends of the movable plate 45, respectively.

[0056] In order to limit the PCB boards of different specifications and sizes, in one embodiment of the present utility model, the limiting component 4 can also include a plurality of limiting clips 46, such as Figure 4 The limiting clip 46 can be provided on the movable plate 45 and is used to move driven by the movable plate 45 to limit the PCB board. A plurality of limiting clips 46 can clamp PCB boards of various sizes.

[0057] In order to avoid damaging the edge of the PCB board when the limit clamp 46 clamps the PCB board, in one embodiment of the present invention, an elastic buffer pad 460 is provided on the side of the limit clamp 46 close to the PCB board to be clamped. The presence of the elastic buffer pad 460 can prevent the limit clamp 46 from directly contacting the edge of the PCB board. The elastic buffering characteristics of the elastic buffer pad 460 can also avoid damaging the edge of the PCB board.

[0058] Through the above technical solution, the clamp for PCB board welding provided by the utility model limits the PCB board through the limiting component, and is suitable for PCB boards of various specifications and sizes. The PCB board is transported to the specified position for welding through the sliding component connected to the limiting component and the push-pull component connected to the sliding component. In combination with the provision of multiple sliding components, the alternating welding of multiple PCB boards is realized, thereby improving the welding efficiency.

[0059] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.

[0060] The above are merely embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
