Description

Technical Field

[0001] The utility model relates to a field, and in particular to an automatic crimping device for PCB terminals with high precision. Background Art

[0002] Currently, the pressing process for small PCBs with terminals relies primarily on conventional jigs. These jigs use a motor- or pneumatic-driven press head to align the PCB with the terminals before pressing. However, for some products requiring high precision, these conventional jigs are no longer sufficient. Furthermore, the preparatory steps before pressing are complex and often require manual fine-tuning, resulting in a low level of automation and efficiency.

[0003] In light of this, this technical solution proposes a high-precision automatic crimping device for PCB terminals. This device utilizes multiple position-limiting structures and an automatic rebound mechanism to achieve fast and accurate crimping. The overall structure is simple and can be operated with a variety of drives (e.g., pneumatic or electric) or manual operation. Furthermore, it offers strong adaptability, allowing for interchangeable crimping of terminals and PCBs of varying specifications. Utility Model Content

[0024] as follows:

[0025] Please see the attached Figure 1-5 ,

[0026] The main structure includes a crimping assembly 2, which includes a slider 23 sleeved on the slide rod 210, a mounting seat 22 provided at one end of the slide rod 210, a pressure head 221 provided at the bottom of the mounting seat, limiting columns 220 provided on both sides of the pressure head 221, a seat body 21 provided on one side of the pressure head 221, a limiting hole 24 corresponding to the limiting column 220 provided on the seat body 21, a fixing groove 25 is provided between the limiting holes, a fixing fixture 26 with a built-in terminal 260 is provided in the fixing groove 25, positioning columns 27 for positioning pcb3 are provided on both sides of the fixing groove 25, and a spring cap 28 for rebounding and resetting the pressure head 221 is also provided on the seat body 21. The pressure head 221 realizes the crimping of pcb3 and terminal 260 through the cooperation of the slider 23 and the slide rod 210.

[0027] Here's how it works:

[0028] Before pressing, first place the terminal 260 to be pressed and the fixing jig 26 in the fixing groove 25 (the fixing jig 26 is regarded as the packaging or package of the finished terminal 260). At this time, the terminal 260 is in a fixed state. Then fix the pcb3 through the positioning column 27. At this time, the pressing point of the pcb3 is facing the terminal 260. Drive the slider 23 downward along the slide rod 210 to make the mounting seat 22 press down with the pressure head 221. The pressure head 221 is mainly limited by the limiting columns 220 on both sides and the limiting holes 24. At this time, the pressure head 221 completes the crimping of the pcb3 and the terminal 260. Since the spring cap 28 is provided, it can automatically rebound after crimping (mainly used for uninterrupted pressing during automatic loading and unloading).

[0029] In a preferred embodiment of the present invention, an external frame shell 1 is provided outside the crimping assembly 2 . The external frame shell 1 includes a back frame 10 framed on the back of the crimping assembly 2 and a base 12 provided at the bottom of the back frame 10 .

[0030] The outer frame 1 is provided mainly to encapsulate the integral crimping assembly 2 so as to facilitate assembly on the device body.

[0031] A preferred embodiment of the present invention is as follows: a slide rail 14 is provided on the base 12 , and the slide rail 14 cooperates with the base body 21 to achieve sliding.

[0032] When connected to the main body of the processing equipment, the slide rail 14 and the base body 21 cooperate to serve as an automatic loading and unloading structure.

[0033] A preferred embodiment of the present invention is as follows: triangular supports 13 are provided on both sides of the back frame 10 .

[0034] The provided triangular support 13 has high strength characteristics to prevent deformation failure after long-term operation.

[0035] In a preferred embodiment of the present invention, a cover 11 is provided on the front side of the slider 23 and the PCB 3 .

[0036] The cover 11 is provided to provide preliminary protection for the PCB 3 and the terminals 260 when they are pressed together.

[0037] In a preferred embodiment of the present invention, the seat body 21 is provided with a guide post 280 which is sleeved in the spring cap 28 .

[0038] The guide post 280 is provided to allow the spring to move downward in a straight line and to reset.

[0039] A preferred embodiment of the present invention is as follows: the bottom surface of the pressing head 221 is provided with a bump corresponding to the PCB3 terminal 260.

[0040] The provided bumps facilitate uniform force during pressing, thereby improving the precision of the joint between the terminal 260 and the PCB 3.

[0041] The above are only preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. All equivalent structural transformations made by using the contents of the description and drawings of the technical solution of the present utility model under the conception of the technical solution of the present utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the present utility model.
