However, the bending of these pins is usually done manually, which is time-consuming, labor-intensive, costly, and inefficient. Furthermore, when the bending operation is relatively complex, deviations in the bending angle and accuracy are easily made, affecting the quality and stability of the PC power supply. Therefore, it is necessary to develop an automatic and adjustable pinning mechanism to solve the above problems.

[0022] The following detailed description of the present invention is provided in conjunction with specific embodiments: In the description of the present invention, it should be noted that the terms "left", "right", "upper", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0023] An adjustable protective cover pinning mechanism, such as Figure 1 As shown, the pinning mechanism includes a base frame 4, a drive module 1 mounted on the upper end of the base frame 4, four pin clamping plate assemblies 2 arranged side-by-side on the lower end of the base frame 4, and a connecting assembly 3. Among them, as... Figure 2As shown, the drive module 1 includes a servo motor and a lead screw assembly 11, a first output end 12, and a second output end 13. The servo motor and lead screw assembly 11 includes a servo motor, lead screws with opposite thread directions at their left and right ends, and some connecting devices. The first output end 12 is sleeved on the right end of the lead screw in the servo motor and lead screw assembly 11, and the second output end 13 is sleeved on the left end of the lead screw. This ensures that when the first output end 12 and the second output end 13 are driven simultaneously by the servo motor, their movement directions are always opposite. Figure 3 As shown, the connecting assembly 3 includes a first connecting rod 31 and a second connecting rod 32; the first connecting rod 31 is fixedly connected to the first output terminal 12; the second connecting rod 32 is fixedly connected to the second output terminal 13; each of the four pin clamping plate assemblies 2 includes a first clamping plate 21 and a second clamping plate 22; and the first clamping plate 21 of each of the four pin clamping plate assemblies 2 is fixedly connected to the first connecting rod 31, and the second clamping plate 22 is fixedly connected to the second connecting rod 32, thereby enabling the drive module 1 to pass through the first connecting rod 31 and the second connecting rod 32. Simultaneously, four pin clamping plate assemblies 2 are driven to open and close, that is, the first clamping plate 21 and the second clamping plate 22 in each pin clamping plate assembly 2 are driven to move towards or away from each other; bending grooves 25 are symmetrically arranged on the facing sides of the first clamping plate 21 and the second clamping plate 22; when the product to be pinned is placed at an appropriate position between the first clamping plate 21 and the second clamping plate 22, the first clamping plate 21 and the second clamping plate 22 can be driven by the drive module 1 to bend the pins of the product to be pinned, realizing the automatic pin bending process. A sensor assembly 5 is provided on the base frame 4 near the second output end 13 to monitor the movement state of the second output end 13, thereby monitoring the opening and closing state of the pin clamping plate assembly 2. In other embodiments, according to actual usage requirements, several pin clamping plate assemblies 2 can be arranged side by side at the lower end of the base frame 4; the sensor assembly 5 can also be arranged on the base frame 4 near the first output end 12; or, one sensor assembly 5 can be arranged on the base frame 4 near both the first output end 12 and the second output end 13.

[0024] Since the pinning products and the pins on them are diverse, the bending grooves 25 symmetrically arranged on the opposing sides of the first clamping plate 21 and the second clamping plate 22 have a fixed shape and limited applicability. They cannot be used for bending different pinning products or pins at different positions on the pinning products. To expand the applicability of this pinning mechanism and meet the bending requirements of different pinning products or pins at different positions on the pinning products, bending clamps 7 of various shapes or structures can be set in the bending grooves 25 for bending the pins. At the same time, the distance between the first clamping plate 21 and the second clamping plate 22 in the pin clamping plate assembly 2 and the clamping distance between the first clamping plate 21 and the second clamping plate 22 can be adjusted by the servo motor and the positive and negative lead screw assembly 11, so that the pinning mechanism can adapt to pinning products of different sizes and can be applied to the production line to automatically complete the pin bending operation of pinning products of different specifications.

[0025] To improve the stability of the pin-forming mechanism, reduce deviations in pin bending angles, and enhance the accuracy and consistency of bending, the pin-forming mechanism also includes a support rod 6. Correspondingly, each of the four pin clamping plate assemblies 2 has a through hole 23 at a corresponding position on the first clamping plate 21 and the second clamping plate 22 for the support rod 6 to pass through. After passing through the through holes 23 on the first clamping plate 21 and the second clamping plate 22, the support rod 6 is fixed at both ends to the two side walls of the base frame 4. This allows the support rod 6 to support the first clamping plate 21 and the second clamping plate 22 while also guiding their movement, preventing swaying or swinging during their relative or opposite movements. This prevents deviations in pin bending angles or reduced accuracy and consistency in pin bending, thus affecting the quality and stability of the PC power supply. Meanwhile, in this pinning mechanism, the upper ends of the first clamping plate 21 and the second clamping plate 22 are both provided with grooves 24 to accommodate the first connecting rod 31 and the second connecting rod 32; this design helps to optimize the structure of the pinning mechanism and reduce its volume.

[0026] In addition, the pinning mechanism also includes a servo Z-axis module 8; such as Figure 4 As shown, the output end of the servo Z-axis module 8 is fixedly connected to the base frame 4 via the connecting plate assembly 9, enabling the pin-pinning mechanism to drive the drive module 1, pin clamping plate assembly 2, and connecting assembly 3 to simultaneously perform lifting and lowering movements via the servo Z-axis module 8. The servo Z-axis module 8 employs a combination of a servo motor and a lead screw; however, in other embodiments, the servo Z-axis module 8 can also be a combination of a cylinder, a motor, and a gear rack, etc., to achieve lifting and lowering.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
