Description

Technical Field

[0001] This utility model relates to the field of lithium battery adhesive technology, and in particular to a lithium battery tape folding and applying mechanism. Background Technology

[0002] After the lithium battery is cut, folded, and heat-pressed, the folded edges need to be secured with adhesive tape. For example... Figure 1 As shown, the tape length is longer than the battery aluminum-plastic film length. To protect the four corners of the battery and to avoid excess tape affecting subsequent battery processes, the excess tape at the four corners needs to be folded up and pasted onto the battery.

[0003] In existing lithium battery excess tape folding processes, the tape is typically folded multiple times manually according to specified folding actions. Moreover, all four corners of the battery need to be folded, which is labor-intensive and inefficient, severely restricting battery production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a lithium battery tape folding mechanism to address the defects and shortcomings of the existing technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a lithium battery tape folding mechanism, which includes a frame and a tape folding and forming assembly mounted on the frame. The tape folding and forming assembly includes a fixed base, a first linear module, a first clamping power module, a second clamping power module, two pressure plates, and two clamping blocks. The first linear module and the first clamping power module are both connected to the fixed base. The first clamping power module causes the two pressure plates to move closer to or further away from each other. The second clamping power module causes the two clamping blocks to move closer to or further away from each other. The first linear module causes the second clamping power module to move closer to or further away from the first clamping power module.

[0007] Furthermore, the number of tape folding and forming assemblies is two; the two tape folding and forming assemblies are symmetrically arranged on the frame.

[0008] Furthermore, the number of the tape folding and forming components is: four tape folding and forming components are arranged in a matrix on the frame.

[0009] Furthermore, two guide rail fixing plates are slidably connected on the frame; two tape folding and forming assemblies are fixed at both ends of one of the guide rail fixing plates; the other two tape folding and forming assemblies are fixed at both ends of the other guide rail fixing plate; a second linear module is connected between the guide rail fixing plates and the frame.

[0010] Furthermore, the second linear module is a second cylinder; the two ends of the second cylinder are respectively connected to the guide rail fixing plate and the frame.

[0011] Furthermore, the sidewall of the guide rail fixing plate is evenly distributed with multiple threaded holes; the length direction of the guide rail fixing plate is perpendicular to the sliding direction of the guide rail fixing plate; the threaded holes are evenly arranged along the length direction of the guide rail fixing plate; the fixing seat is slidably connected to the guide rail fixing plate; the fixing seat is provided with a strip-shaped hole; the length direction of the strip-shaped hole extends along the length direction of the guide rail fixing plate; two bolts pass through the strip-shaped hole and are threadedly connected to the two threaded holes.

[0012] Furthermore, a scale is fixed on the guide rail fixing plate.

[0013] Furthermore, the first clamping power module consists of two first forming cylinders arranged opposite each other; the piston rod ends of the two first forming cylinders are respectively connected to two pressure plates; the outer shell of the first forming cylinder is fixed on the fixed base.

[0014] Furthermore, the second clamping power module is a gripper cylinder; two gripping blocks are respectively fixed on the two gripping toes of the gripper cylinder; the outer shell of the gripper cylinder is fixed on the fixed base.

[0015] Furthermore, the first linear module is a first cylinder, and the two ends of the first cylinder are respectively connected to the second clamping power module and the fixed base.

[0016] The beneficial effects of this utility model after adopting the above structure are as follows: First, the tape to be folded extends between the upper and lower pressure plates, and the first linear module is activated, moving the two clamping blocks below the position where the tape needs to be folded; Second, the first clamping power module drives the pressure plates to approach and mesh with each other, pressing the tape tightly so that the upper and lower sides of the tape are adhered; with the bottom surface of the upper pressure plate as a reference, the upper surface of the tape adheres to the upper pressure plate; Third, the second clamping power module drives the two clamping blocks to move upwards, moving the tape from step [the previous step] to step [the next step]. The second step involves the tape extending from one end of the pressure plate and bending upwards. The third step involves the first clamping power module moving the pressure plates away from each other while the second clamping power module moves the two clamping blocks away from each other. The first linear module moves the clamping blocks towards the tape, causing the upward-bent portion of the tape to extend between the two clamping blocks and bend the tape into an acute angle. The fourth step involves the second clamping power module moving the two clamping blocks closer together and engaging to fold the bent section of the tape onto the tape. This structure enables automatic tape folding, maximizing folding efficiency and reducing labor intensity. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings.

The first linear module 107 and the first clamping power module are both connected to the fixed base 103. The first clamping power module causes the two pressure plates 102 to move closer to or further away from each other. The second clamping power module causes the two clamping blocks 108 to move closer to or further away from each other. The first linear module 107 causes the second clamping power module to move closer to or further away from the first clamping power module.

[0031] The first step is to insert the tape into the space between the upper and lower pressure plates 102 at the position where it needs to be folded, and the first straight module 107 is activated to move the two clamping blocks 108 below the position where the tape needs to be folded.

[0032] The second step is that the first clamping force drives the pressure plates 102 to approach and bite each other, and the pressure plates 102 press the tape tightly so that the upper and lower sides of the tape are adhered.

[0033] Using the bottom surface of the upper pressure plate 102 as a reference, the upper surface of the tape adheres to the upper pressure plate 102;

[0034] Third step, the second clamping power module drives the two clamping blocks 108 to move upward, bending the end of the tape that extends out of the pressure plate 102 in step two upward;

[0035] Fourth step: while the first clamping power drives the pressure plate 102 to move away from each other, the second clamping power module drives the two clamping blocks 108 to move away from each other. The first linear module 107 drives the clamping blocks 108 to move towards the tape, so that the tape bent upwards extends between the two clamping blocks 108 and bends the tape into an acute angle.

[0036] Fifth step, the second clamping power module drives the two clamping blocks 108 to approach each other and bite together, folding the bent section of the tape onto the tape;

[0037] This structure enables automatic folding of the tape, maximizing folding efficiency and reducing labor intensity.
