[0027] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0028] See Figures 1-7 The diagram schematically illustrates a lithium battery cover riveting assembly mechanism according to this disclosure, comprising a frame 1. The frame 1 is equipped with a lower mold base 2, an upper mold base 3, a first drive mechanism 4, and a stop assembly 5. The upper mold base 3 is located above the lower mold base 2, and the lower mold base 2 and upper mold base 3 are correspondingly fitted. A first support column 21 is provided on the lower mold base 2, and a first pressure column 31 corresponding to the first support column 21 is provided on the upper mold base 3. The first drive mechanism 4 drives the lower mold base 2 to move up and down, causing the lower mold base 2 and upper mold base 3 to close and open. The number and arrangement of the first support columns 21 and the first pressure columns 31 are determined according to the specific product and the number of products riveted at one time.

[0029] During use, the corresponding conveying device transports the fixture containing the lithium battery cover to the space between the lower mold base 2 and the upper mold base 3. The baffle assembly 5 first blocks and positions the fixture, and then the first drive mechanism 4 drives the lower mold base 2 to move upward, causing the lower mold base 2 and the upper mold base 3 to close. As the lower mold base 2 and the upper mold base 3 close, the first support column 21 and the first pressure column 31 cooperate to complete the riveting process of the product placed on the fixture. After the mold is opened, the corresponding conveying device outputs the fixture again, and this operation is repeated continuously to realize the automatic riveting assembly of the lithium battery cover, such as riveting the positive and negative terminals on the lithium battery cover. With the lower mold base 2 and the upper mold base 3 closing, the first support column 21 and the first pressure column 31 cooperate to pre-press the product before riveting, which is more stable and reliable.

[0030] The first drive mechanism 4 can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, linear module, etc. If the first drive mechanism 4 is an electric cylinder, its output end is connected to a pressure sensor 41, which is connected to the lower mold base 2. This results in higher precision, more stable and reliable movement, and more convenient control.

[0031] The frame 1 is equipped with a stroke detection component 6 that cooperates with the up-and-down movement of the lower mold base 2, facilitating more precise control of the movement of the lower mold base 2. The stroke detection component 6 can be a linear encoder, with one end of the first connecting rod connected to the lower mold base 2 and the other end connected to the reading head of the linear encoder. This design is simple, easy to operate, and more stable and reliable. Alternatively, the stroke detection component 6 can also employ other suitable detection elements from existing technologies, such as limit switches.

[0032] The frame 1 is equipped with a first detection component 7 for detecting fixtures, such as a photoelectric switch or an infrared sensor. The number and arrangement of the first detection components 7 are determined according to specific circumstances. For example, two first detection components 7 can be symmetrically arranged at the feed end and the discharge end respectively. During operation, a signal is fed back to the control system only when a fixture is detected between the lower mold base 2 and the upper mold base 3. The control system then controls the first drive mechanism 4 to drive the lower mold base 2 to move, thereby preventing damage to the equipment due to lack of material during air compression, making it safer and more reliable.

[0033] The material blocking assembly 5 includes a first bracket 51, on which a first connecting seat 52 and a second drive mechanism 53 are mounted to drive the first connecting seat 52 to move up and down are provided.

The second drive mechanism 53 drives the first connecting seat 52 to move up and down, so that the first stop wheel 54 on the first connecting seat 52 can block and position the fixture, preventing the fixture from falling out. The second drive mechanism 53 can be a cylinder, hydraulic cylinder, electric cylinder, linear module, etc. For example, using a cylinder results in a simple and compact structure, convenient installation and maintenance, and is safe and environmentally friendly. The first stop wheel 54 can be an elastic or flexible component, which can buffer and protect, reduce damage and noise, etc. A rotating shaft that is rotatably connected to the first stop wheel 54 can be mounted on the first connecting seat 52.

The number and arrangement of the first elastic elements 34 are determined according to specific circumstances. When the mold is closed, the first stripper plate 32 is moved upward under force, and the first elastic element 34 is compressed at the same time. When the mold is opened, the first elastic element 34 can push the first stripper plate 32 to move downward automatically for reset, which facilitates stripping.

[0035] The upper mold base 3 is provided with a first guide rod 33, which is arranged vertically.
