[0003] like Figure 1 and Figure 2 As shown, the terminal 100 includes an electrode sheet 110 and a screw 120. The electrode sheet 110 has a mounting end face 111 corresponding to the screw 120, and a matching hole 112 is provided on the electrode sheet 110 and located on the mounting end face 111. In the processing technology of the terminal, there is a process that requires pressing the screw 120 into the matching hole 112, so that the screw 120 and the matching hole 112 are interference fit to complete the riveting.

[0036] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment," "in some embodiments," or "in some embodiments" appear in various places throughout this specification, not all references are to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0037] Please refer to Figures 3 to 12 As shown, a terminal riveting mechanism provided by an embodiment of the present invention is now described. The terminal riveting mechanism provided by an embodiment of the present invention includes a mounting platform 2, a positioning platform 3 provided on the mounting platform 2 for placing a terminal 100, a pressing head 4, and a pressing member 5 provided above the pressing head 4, a first driver 21 is installed on the mounting platform 2, the pressing head 4 includes a base 41 connected to the output end of the first driver 21, a pressing rod 42 slidably mounted on the base 41, and a first elastic member 43, the first elastic member 43 is installed between the pressing rod 42 and the base 41 to push the pressing rod 42 toward moving away from the positioning platform 3 by elastic force, the first driver 21 can drive the base 41 to move above the positioning platform 3 or detach from the positioning platform 3, when the base 41 moves above the positioning platform 3, the base 41 presses on the electrode sheet 110 in the terminal 100, and the pressing member 5 can make a linear motion relative to the positioning platform 3, so that the pressing member 5 pushes the pressing rod 42 in the pressing head 4 toward the positioning platform 3 to push the screw 120 to be fixed on the electrode sheet 110. Therefore, when the lower pressing member 5 pushes against the pressing rod 42 and thus pushes against the screw 120 to be riveted and fixed on the electrode sheet 110, since the base 41 in the pressure head 4 presses on the electrode sheet 110 in the terminal 100, it can limit the irregular deformation of the electrode sheet 110 and avoid warping and deformation of the mounting end surface 111 on the electrode sheet 110.

[0038] like Figure 5 As shown, in some embodiments, the positioning platform 3 is provided with a mounting position 31 suitable for placing the electrode sheet 110, and the positioning platform 3 is also provided with a receiving cavity 321 for inserting the screw 120. Therefore, after the electrode sheet 110 and the screw 120 are combined, they can be placed on the positioning platform 3, and the positions of the electrode sheet 110 and the screw 120 on the positioning platform 3 are guaranteed to be unique. In this embodiment, the mounting position 31 is a groove provided on the upper end surface of the positioning platform 3.

[0039] like Figure 6As shown, in some embodiments, a sliding hole 33 is provided on the positioning platform 3 in a direction perpendicular to the upper end surface of the positioning platform 3, and a top block 32 is slidably installed in the sliding hole 33. The interior of the top block 32 is hollow to form a receiving cavity 321. A through hole 22 is opened on the mounting platform 2 corresponding to the bottom of the top block 32. The terminal riveting mechanism also includes a second driver 6 mounted on the mounting platform 2. The output end of the second driver 6 is connected to the top block 32 through the through hole 22. The second driver 6 can drive the top block 32 to slide in the sliding hole 33, so that after the terminal 100 is riveted, the second driver 6 can drive the top block 32 to move upward to eject the terminal 100 from the positioning platform 3, thereby realizing the blanking action. In this embodiment, the second driver 6 is a linear cylinder.

[0040] like Figure 4 As shown, in some embodiments, the base 41 is slidably connected to the mounting platform 2 along a horizontal direction, so that the base 41 can be firmly pressed against the electrode sheet 110 to prevent the electrode sheet 110 from warping and deformation.

[0041] like Figure 7 and Figure 8 As shown, in some embodiments, a avoidance groove 412 is provided on the base 41 corresponding to the screw 120 in the terminal 100, and a holding surface 414 is provided at the bottom of the base 41 and around the avoidance groove 412, so that the base 41 can be moved above the positioning platform 3, so that the screw 120 is received in the avoidance groove 412, and the holding surface 414 is pressed on the electrode sheet 110 around the screw 120, effectively eliminating the irregular deformation caused by the screw 120 squeezing the matching hole 112 on the electrode sheet 110.

[0042] like Figure 9 As shown, in some embodiments, a guide hole 413 is provided on the base 41 corresponding to the pressure rod 42. The pressure rod 42 is slidably installed in the guide hole 413. The top of the pressure rod 42 is provided with an end 411. The first elastic member 43 is sleeved on the pressure rod 42 and pressed between the end 411 and the base 41. When the pressure rod 42 is in a free state, it is pushed upward by the first elastic member 43 to move away from the positioning platform 3. When the end 411 is pressed downward by the downward pressure member 5, it drives the pressure rod 42 to resist the downward movement of the first elastic member 43 and press down toward the positioning platform 3, thereby riveting the screw 120 to the electrode sheet 110. In this embodiment, the first elastic member 43 is a coil spring.

[0043] like Figure 10 、 Figure 11 ,as well as Figure 12As shown, since the pressing surface 414 at the bottom of the base 41 always maintains the mounting end surface 111 of the electrode sheet 110 during the process of the pressure rod 42 pressing down the screw 120, even if the screw 120 and the matching hole 112 of the electrode sheet 110 are interference fit to cause the electrode sheet 110 to deform, the electrode sheet 110 will not undergo irregular deformation, but will produce a trace amount of material transfer around the matching hole 112, and the slight deformation will not cause a significant change in the outline of the electrode sheet 110.

[0044] like Figure 3 As shown, in some embodiments, the terminal riveting mechanism provided by the embodiments of the present invention also includes a base 1, the mounting platform 2 is installed on the base 1, and the pressing piece 5 is slidably installed on the base 1 toward the positioning platform 3. Specifically, the pressing piece 5 is slidably fitted with a guide rod 51, the guide rod 51 is fixedly connected to the base 1, and a second elastic member 52 is installed between the guide rod 51 and the pressing piece 5. The second elastic member 52 is used to push the pressing piece 5 to move away from the positioning platform 3 through elastic force, so that the pressing piece 5 can be driven by the power source to slide on the base 1 close to the positioning platform 3, and reset to a position away from the positioning platform 3 when the power source drive is lost.

[0045] In some embodiments, a limit block 53 is installed on the pressing member 5 and close to the positioning platform 3. The limit block 53 is used to press against the mounting platform 2 when the pressing member 5 is pressed into place to limit the displacement of the pressing member 5 and serve as an overtravel protection.

[0046] It can be understood that when the terminal riveting mechanism provided in the embodiments of the present invention is working, the lower pressure piece 5 is driven by a power source. In some embodiments, the power source can be a hydraulic press having a table and a movable part located above the table. The movable part can make a linear reciprocating motion relative to the table under the hydraulic power of the hydraulic press to drive the lower pressure piece 5 to move for riveting.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
