Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of batteries, and more specifically, to an adjusting roller clamp structure and a laminator. Background Art
[0002] During the process of producing battery cells by a high-speed thermal composite laminator, panoramic CCD detection is an important process for verifying whether the tape is defective and providing accurate real-time feedback. The roller clamp structure is the most important structure except for the vision part, and the main technical problems it solves include providing stable clamping (ensuring the stability of the tape and avoiding shaking), precise positioning (improving the accuracy of detection), and improving detection efficiency, etc.
[0003] After research by the inventor, it is found that the roller clamp structures currently applied to panoramic CCD detection of laminators are roughly mechanical roller clamp structures, pneumatic roller clamp structures, electromagnetic roller clamp structures, and combined roller clamp structures, etc. The emergence of these structures makes it possible to achieve high-precision image acquisition and processing in CCD detection. These solutions have their own advantages and disadvantages, and can be reasonably selected or combined according to the usage scenario. In actual design, factors such as the adjustment of clamping force, clamping accuracy, stability, and reliability also need to be considered. The existing roller clamp mechanisms in the current technology usually cannot actively adjust the gap width of the roller clamp channel, but can only passively adjust according to the thickness of the electrode sheet. Therefore, for electrode sheets of different thicknesses, it is difficult to achieve good motion control, and it is difficult to reduce the impact and vibration of the tape during transmission, resulting in disadvantages such as precision limitation, adaptability limitation, and easy wear.

Of course, in other preferred embodiments of the present utility model, the elastic adjusting component 170 may also be arranged only on the first side frame 111 or only on the second side frame 113, which is not limited herein.

The elastic adjustment assembly 170 is elastically connected to the first over-roller assembly 130 and can adjust the gap width of the roller clamping channel by driving the first over-roller assembly 130 to move, achieving good motion control. It can be adjusted according to the pole piece specifications, so that the gap width is more suitable for the pole piece, reducing the impact and vibration of the pole piece strip during transmission, thereby improving the transmission accuracy and service adaptability, reasonably clamping the pole piece, and reducing wear.
[0039] In this embodiment, slide rails 190 extending in the vertical direction are arranged on the opposite side walls of the first side frame 111 and the second side frame 113.

[0040] Furthermore, the elastic adjustment assembly 170 includes an adjustment arm 171, an adjustment member 173, and an elastic member 175. The adjustment arm 171 is fixedly arranged at the top of the first side frame 111 or the second side frame 113 and bends and extends towards the roller clamping channel. The adjustment member 173 is arranged on the adjustment arm 171 and can be adjusted up and down relative to the adjustment arm 171. The elastic member 175 is arranged at the bottom end of the adjustment member 173 and is connected to the end of the first over-roller assembly 130, and the elastic member 175 is used to provide an elastic force towards the second over-roller assembly 150 to the first over-roller assembly 130. Specifically, adjustment arms 171 are arranged at the tops of both the first side frame 111 and the second side frame 113. The adjustment arms 171 are bent. The adjustment member 173 can be installed on the horizontal section of the adjustment arm 171 and can be adjusted up and down relative to the adjustment arm 171, so as to adjust the vertical height of the elastic member 175 and the first over-roller assembly 130.
[0041] Preferably, the adjusting member 173 includes an adjusting bolt. A threaded hole is formed in the adjusting arm 171, and the adjusting bolt is threadedly assembled in the threaded hole. The elastic member 175 includes a spring, and the spring is compressively disposed between the adjusting bolt and the end of the first over-roller assembly 130. Specifically, the spring is compressively disposed so as to be able to provide an elastic force to the first over-roller assembly 130. Moreover, by adjusting the up-and-down position of the adjusting bolt, the spring can adaptively change the reference position, and thus can provide an almost constant elastic force to the first over-roller assembly 130 to ensure the roller clamping effect.
[0042] It should be noted that the top end of the spring is fixedly connected to the adjusting bolt, and the bottom end of the spring elastically abuts against the end of the first over-roller assembly 130. In this embodiment, the top end of the spring can be fixedly connected to the adjusting bolt, and the bottom end can elastically abut against the end of the first over-roller assembly 130.
[0043] The first over-roller assembly 130 includes a first pole-piece over-roller 131 and a first mandrel 133. Both ends of the first mandrel 133 are connected to the slider 191.

Specifically, the first pole-piece over-roller 131 can adopt a carbon fiber anti-slip roller to ensure the clamping force.
[0044] Furthermore, fixing blocks 135 are provided at both ends of the first mandrel 133. The fixing blocks 135 are connected to the slider 191 and move synchronously with the slider 191. The elastic adjusting assembly 170 is connected to the fixing blocks 135. Specifically, the fixing blocks 135 and the slider 191 can be a detachable connection structure, such as clamping and fixing. After installation, the synchronous movement between the fixing blocks 135 and the slider 191 can be achieved. The spring abuts against the top end of the fixing block 135 and can apply a downward elastic force through the fixing block 135.
[0045] The second over-roller assembly 150 includes a second pole-piece over-roller 151 and a second mandrel 153. Both ends of the second mandrel 153 are respectively connected to the first side frame 111 and the second side frame 113. The second pole-piece over-roller 151 is rotatably sleeved outside the second mandrel 153 and is located in the middle of the second mandrel 153. The first pole-piece over-roller 131 and the second pole-piece over-roller 151 are arranged corresponding to each other and form a roller clamping channel. Among them, the second pole-piece over-roller 151 can also adopt a carbon fiber anti-slip roller and has the same width as the first pole-piece over-roller 131 to ensure the clamping force. The spring is used in cooperation with the first pole-piece over-roller 131 and the second pole-piece over-roller 151 to provide the clamping force, and the up-and-down movement of the first pole-piece over-roller 131 is precisely controlled by the slide rail 190 and the adjusting bolt, so as to realize the precise clamping and positioning of the strip.
[0046] In this embodiment, stoppers 193 are provided at both ends of the slide rail 190, and the stoppers 193 are used to limit the slider 191 on the slide rail 190. Specifically, stoppers 193 are provided at both the upper and lower ends of the slide rail 190, and the stoppers 193 can abut against the upper and lower ends of the slider 191, thereby limiting the up and down sliding range of the slider 191 and preventing the slider 191 from falling off.
[0047] In summary, for the adjusting roller clamp structure 100 provided in the embodiment of the present utility model, a first over-roller assembly 130 and a second over-roller assembly 150 are arranged between the first side frame 111 and the second side frame 113 of the roller clamp frame 110.
