[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figures 1-6 As shown, this utility model discloses a non-destructive crimping terminal device, comprising: Workbench 1, on which a mounting base 11 is provided, the mounting base 11 being slidably connected to the workbench 1; The pre-compression assembly 2 includes a support frame 21 and a pressing cylinder 22. The support frame 21 is mounted on the workbench 1, and the pressing cylinder 22 is mounted on the support frame 21. The extension and retraction of the pressing cylinder 22 is directly opposite the mounting base 11, and multiple pressing needles 23 are arranged side by side at the extension and retraction end of the pressing cylinder 22. The pressing assembly 3 includes a linear module 31, an adjusting cylinder 32, and a pressing block 33. The linear module 31 is disposed on one side of the support frame 21 along the extension and retraction direction of the pressing cylinder 22. The adjusting cylinder 32 is connected to the slide of the linear module 31, and the extension and retraction direction of the adjusting cylinder 32 is perpendicular to the axial direction of the linear module 31. The pressing block 33 is disposed at the extension and retraction end of the adjusting cylinder 32. A pressing rod 34 is disposed at the bottom of the pressing block 33, and the axial direction of the pressing rod 34 is consistent with the distribution direction of the plurality of pressing needles 23.

[0019] Specifically, refer to Figure 2 As shown, the mounting base 11 on the workbench 1 is used to install the product. The product is provided with mounting holes, and terminals are installed in the mounting holes. The mounting base 11 is slidably connected to the workbench 1, and the product can be adjusted to different pressing positions.

[0020] Reference Figure 5 As shown, the terminal pressing in this invention includes two steps. The pre-pressing component 2 is used to pre-press the terminal, ensuring it is stably pressed into the product and thus securing it. Specifically, the pressing cylinder 22 drives the pressing pins 23 to move up and down. The pressing pins 23 press down to contact the terminal, pressing it into the mounting hole. The axial direction of the pressing pins 23 is consistent with the axial direction of the terminal, and the spacing between the multiple pressing pins 23 is the same as the spacing between the multiple terminals, preventing the terminals from scratching the product during pressing. In actual operation, the pressing pressure of the terminal is controlled by controlling the extension and retraction length of the pressing cylinder 22, thus preventing terminal deformation.

[0021] Reference Figure 6 As shown, the pressing assembly 3 applies secondary pressure to multiple terminals to ensure the strength of the terminal pressing. Specifically, in actual operation, the adjusting cylinder 32 is used to adjust the horizontal position of the pressing rod 34, and the adjusting cylinder 32 drives the pressing rod 34 to the top of multiple terminals; the linear module 31 drives the pressing rod 34 to move downward, so that the pressing rod 34 contacts multiple terminals, and continues to press down to press multiple terminals into the product, so that multiple terminals are pressed into place, ensuring stable contact between the terminals and the product, and improving the reliability of the pressing.

[0022] Furthermore, a lead screw 12 is provided on the surface of the workbench 1, and the mounting base 11 is connected to the lead screw 12. The lead screw 12 drives the mounting base 11 to reciprocate between the support frame 21 and the linear module 31.

[0023] Specifically, this invention uses a lead screw 12 to drive the mounting base 11, ensuring the stability and accuracy of the mounting base 11's position adjustment, and guaranteeing the accuracy of the subsequent pre-pressing and secondary pressing positions of the terminals. In actual operation, the lead screw 12 first moves the mounting base 11 to the bottom of the pressing cylinder 22. After the pre-pressing action is completed, the lead screw 12 moves the mounting base 11 to the bottom of the linear module 31, and the linear module 31 drives the pressure rod 34 to press down for the secondary pressing of the terminals.

[0024] Furthermore, a first guide rail 13 is provided between the mounting base 11 and the worktable 1, and the first guide rail 13 is arranged axially along the lead screw 12. The first guide rail 13 further improves the stability of the movement of the mounting base 11, facilitates the alignment of the pressure pin 23 and the pressure rod 34 with the terminal, and improves the accuracy of terminal pressing.

[0025] Furthermore, referring to Figure 3 As shown, the mounting base 11 has a mounting groove 111 inside, and a limiting bracket 14 is provided on the mounting base 11. One side of the limiting bracket 14 extends into the mounting groove 111. The surface of the side of the limiting bracket 14 that extends into the mounting groove 111 is provided with a plurality of limiting grooves 142.

[0026] Specifically, the mounting base 11 is used to install the product (box), and the limiting bracket 14 is set on the side wall of the top of the mounting base 11. One end of the limiting bracket 14 extends into the mounting groove 111 to limit the installation of the terminal. In actual operation, the product is first placed in the mounting groove 111, and then the limiting bracket 14 is installed. The terminal is then manually placed in the mounting hole of the product, and the terminal is fixed by the limiting groove 142 to prevent the terminal from shaking during the adjustment of the mounting base 11, which would affect the accuracy of subsequent pressing.

[0027] Furthermore, referring to Figure 4 As shown, the surface of the mounting base 11 is provided with a positioning pin 112, and the limiting frame 14 is provided with a positioning hole 141 that cooperates with the positioning pin 112.

[0028] Specifically, in actual operation, the terminal installation positions of different product models are different, requiring the replacement of different limit brackets 14 to adapt to terminals with different spacing. The installation of the limit bracket 14 is achieved by the engagement of the positioning hole 141 on the limit bracket 14 with the positioning pin 112 on the mounting base 11, thus realizing a detachable connection.

[0029] Furthermore, an installation plate 36 is provided between the adjusting cylinder 32 and the linear module 31, and a second guide rail 37 is provided between the pressure block 33 and the installation plate 36.

[0030] Specifically, the mounting plate 36 is used to install the adjusting cylinder 32 and the pressure block 33. The second guide rail 37 can guide the horizontal movement of the pressure block 33, so that the pressure block 33 moves stably and ensures the accuracy of subsequent terminal pressing actions.

[0031] Furthermore, an auxiliary pressure plate 35 is also provided on the mounting plate 36. The auxiliary pressure plate 35 is located at the end of the pressure rod 34 away from the pressure block 33. The bottom of the auxiliary pressure plate 35 is flush with the top of the pressure rod 34.

[0032] Specifically, in this invention, the pressure block 33 and the pressure rod 34 are integrally formed. Because the axial length of the pressure rod 34 is relatively long, it is difficult for the linear module 31 to ensure uniform pressure across the entire surface of the pressure rod 34 during the pressing process. This invention addresses this by providing an auxiliary pressure plate 35 at the end of the pressure rod 34 furthest from the pressure block 33. During actual pressing, the auxiliary pressure plate 35 balances the pressure across the entire surface of the pressure rod 34, ensuring consistent pressure on multiple terminals during pressing and further guaranteeing the reliability of terminal pressing.

[0033] Furthermore, the telescopic end of the pressing cylinder 22 is provided with a mounting block 24, and the pressing needle 23 is detachably connected to the mounting block 24.

[0034] Specifically, in actual operation, the corresponding mounting block 24 is selected according to the number and size of the mounting holes inside the product, and is used to install different numbers and models of terminals.

[0035] In summary, this utility model introduces a non-destructive terminal crimping device. The specific operating steps are as follows: First, the product is placed in the mounting base 11, which is equipped with a limiting bracket 14. The terminal is manually placed at the port of the mounting hole. The lead screw 12 drives the mounting base 11 to move the product (box) to the bottom of the pressing cylinder 22. The pressing cylinder 22 drives the pressing pin 23 to pre-press the terminal. The lead screw 12 drives the mounting base 11 again to move the product to the bottom of the linear module 31. The linear module 31 moves to drive the pressing rod 34 to press multiple terminals a second time, finally making the terminal firmly installed in the product. This utility model solves the problem of product deformation caused by manual operation, avoids the situation of manual insertion not being in place or causing scratches on the surface, ensures that multiple terminals are pressed in place, guarantees stable contact between the terminal and the product, and improves the reliability of pressing.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
