Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please refer to Figure 1-6 ;

[0031] The core-binding device of this utility model can perform multi-directional adhesive application on the edge of a soft-pack battery, improving work efficiency; specifically, it includes a movable clamp 2 and a core-binding mechanism 1; the movable clamp 2 includes a movable component 21, a rotary cylinder 22 is installed on the movable end of the movable component 21, a lower clamping block 23 is installed on the rotary cylinder 22, an upper clamping block 24 is used in conjunction with the lower clamping block 23, the upper clamping block 24 is connected to a lifting component, the upper clamping block 24 and the lower clamping block 23 are combined to form a clamp, and a plurality of adhesive-binding positions 25 are formed on its outer periphery; the core-binding mechanism 1 has at least one unit;

[0032] The soft-pack batteries processed by this equipment are quadrilateral, specifically rectangular. To simplify the structure, the upper clamping block 24 and the lower clamping block 23 are combined to form a cuboid clamp. The adhesive bonding position 25 is a notch, which is provided on all four sides of the clamp. According to the length of the soft-pack battery, multiple adhesive bonding positions 25 are provided along the side length direction to make the soft-pack battery more secure. Although the upper clamping block 24 and the lower clamping block 23 can clamp the soft-pack battery, in order to prevent it from shifting during adhesive bonding, a lower structure is formed between the upper and lower clamping blocks 23 to completely fix the soft-pack battery.

[0033] During operation, the upper clamping block 24 and the lower clamping block 23 separate. The soft-pack battery is placed on the lower clamping block 23. Then, the upper clamping block 24 is pushed downward by the lifting component (not shown) to close with the lower clamping block 23, forming a clamp to fix the soft-pack battery.

[0034] In Example 1, there is only one core-binding mechanism 1. At this time, the output end of the core-binding mechanism 1 corresponds to one of the adhesive binding positions 25. Then the adhesive binding mechanism starts to move, extends into the adhesive binding position 25 and attaches the tape to the edge of the soft-pack battery. After that, the core-binding mechanism withdraws from the adhesive binding position 25. When there are several adhesive binding positions 25 on the same side, the clamp is pushed to move laterally by the moving component 21, so that another adhesive binding position 25 corresponds to the core-binding mechanism 1 to perform the adhesive binding operation. After the adhesive binding operation on the same side is completed, the clamp is rotated by the rotating cylinder 22, so that the adhesive binding position 25 on the other side corresponds to the adhesive binding mechanism to perform the adhesive binding operation, and so on.

[0035] In Example 2, there are three core-binding mechanisms 1, corresponding to the three directions of the fixture respectively. One direction is left empty for feeding. Unlike the operation method in Example 1, the core-binding mechanisms 1 in multiple directions can operate simultaneously to attach the tape to the soft-pack battery. When the fixture has two binding positions 25 in the length direction on both sides and one binding position 25 in the width direction, there are six binding positions 25. First, the three core-binding mechanisms 1 correspond to three of the binding positions 25, and the three core-binding mechanisms 1 operate simultaneously. Then, the fixture is rotated 180° by the rotary cylinder 22, so that the three core-binding mechanisms 1 correspond to the other three binding positions 25 and operate simultaneously. Furthermore, assuming there are more than two binding positions 25 in the length direction, the fixture can be moved laterally by the moving component 21, so that the other binding positions 25 on the same side correspond to the core-binding mechanism 1.

[0036] This invention utilizes the combined use of the moving component 21 and the rotating cylinder 22 to change the position and direction of the clamp, enabling the core-binding mechanism 1 to perform adhesive application on multiple positions of the soft-pack battery. The operation is simple and efficient. When multiple core-binding mechanisms 1 are installed, they can simultaneously apply adhesive to multiple directions of the soft-pack battery. Furthermore, multiple adhesive application operations on the outer periphery of the soft-pack battery can be completed with just one rotation, further improving work efficiency.

[0037] Given the complexity of the current core-binding mechanism 1, this embodiment provides a simpler structure.

[0038] Specifically, it includes a second moving component 11, a first fixed plate 12 installed at the moving end of the second moving component 11, a transverse moving component 13 installed on the first fixed plate 12, a movable plate 14 connected to the transverse moving component 13, the movable plate 14 being slidably connected to the first fixed plate 12, a storage wheel 15, an adhesive applicator 16 and a cutting component 17 installed on the movable plate 14, the outer end of the adhesive applicator 16 being provided with an adhesive groove 163 for the soft rubber battery to enter, and the storage wheel 15 containing adhesive tape; it should be noted that the fixed plate should be provided with a transition wheel that cooperates with the storage wheel 15, which is a common technical means, and the design can be made with reference to the prior art, but there are some differences, that is, the adhesive side of the adhesive tape output by the storage wheel 15 faces upward, therefore, an anti-stick coating is provided on the surface of the transition wheel;

[0039] First, pull the tape out of the storage wheel 15, allowing it to pass over the surface of the adhesive application assembly 16 and extend to the opening of the adhesive application groove 163. During operation, the soft-pack battery is conveyed to the adhesive application position via a conveying device. At this time, the soft-pack battery is positioned sideways and corresponds to the opening of the adhesive application groove 163. Then, the entire assembly is lowered by the moving component 11, and the movable plate 14 is pushed out by the transverse component 13, so that the end of the adhesive application assembly 16 is below the soft-pack battery, and the adhesive application groove 163 is also below the soft-pack battery. Simultaneously, the tape is applied to the bottom edge of the soft-pack battery. The rear moving component 11 and the transverse moving component 13 move upward in a "C" shape. Since the tape is already fixed to the bottom of the soft-pack battery, the larger part of the storage wheel 15 will be pulled out during the movement, so that the edge of the soft-pack battery can be inserted into the adhesive groove 163, and the tape will be pasted on the edge of the soft-pack battery in a "C" shape. The tape may not be firmly attached to the bottom of the soft-pack battery. After the soft-pack battery is inserted into the adhesive groove 163, the tape on the bottom side of the adhesive groove 163 will be smoothed out.

[0040] In this embodiment, the cutter 173 in the cutting component 17 is placed in the adhesive groove 163 and can extend out of the adhesive groove 163 to cut the upper adhesive tape. Finally, it is reset under the action of the moving component 11 and the transverse component 13, and the cutter 173 retracts into the adhesive component 16 to complete the whole action. Preferably, the height of the adhesive groove 163 is greater than the height of the soft pack battery. The upper end surface of the cutter 173 is provided with a bevel 174 and the lower end surface is a plane 175. When the cutter 173 extends, it is close to the upper end surface of the soft pack battery, cutting the adhesive tape while smoothing the upper end surface of the soft pack battery.

[0041] This invention achieves a "C"-shaped movement by cooperating with the moving component 11 and the transverse component 13, allowing the soft-pack battery to be placed in the adhesive tray 163 for tape application. Compared with the prior art, it eliminates the need to straighten both ends of the tape before applying it. During the tape application process, not only is the tape applied to the soft-pack battery, but the tape can also be pulled out from the storage wheel 15 to complete the extension action. No additional power device is required, simplifying the overall structure and further improving work efficiency.

[0042] One embodiment of the present invention relates to an adhesive applicator 16, specifically including a second fixing plate 161, which is horizontally placed. Two corresponding clamping strips 162 extend outward from the side of the second fixing plate 161, and an adhesive applicator groove 163 is formed between the two clamping strips 162. A channel 164 for the adhesive tape to pass through is formed above the second fixing plate, and the channel 164 corresponds to the clamping strips 162. The adhesive applicator channel 164 can better guide the adhesive tape.

[0043] Furthermore, a pressure block 165 is provided on the channel 164. Since the adhesive side of the tape is facing upward, the pressure block 165 will contact the adhesive side. Therefore, the end face of the pressure block 165 is provided with an anti-stick coating. The pressure block 165 is rotatably connected to the fixing block 166. The fixing block 166 can be installed on the movable plate 14 of the fixing plate or on the second fixing plate 161. A pneumatic pressure rod 167 is installed above the fixing block 166. The pneumatic pressure rod 167 faces downward and can abut against the end face of the pressure block 165.

[0044] Normally, the pressure block 165 simply hangs down in the channel 164 by gravity to press the tape tightly, without affecting the pulling of the tape. When it is necessary to cut the tape, the pneumatic pressure rod 167 needs to be activated to apply pressure to the pressure block 165, so that the pressure block 165 presses the tape tightly, avoiding pulling the tape during the cutting process. After the cutting is completed, the pneumatic pressure rod 167 retracts and resets.

[0045] Preferably, an air hole 168 is provided on the upper end face of the fixing plate 161 to provide negative pressure to hold the tape in place and prevent the tape from drifting.

[0046] One embodiment of the cutting assembly 17 of this utility model specifically includes a driver 171, a movable block 172 connected to the driver 171, the movable block 172 being slidably connected to the movable plate 14, a cutter 173 mounted on the movable block 172, the cutter 173 being located on the side of the clamping strip 162 and laterally inserted into the adhesive groove 163, thus allowing the cutter 173 to be fixed from the side, the movable block 172 having a laterally extending fixing part for mounting the cutter 173, the side mounting method of the cutter 173 allows for better observation of the cutter 173 and easier maintenance of the cutter 173, and saves more space compared to the method of entering from the back of the fixed plate 161, the extension and retraction of the cutter 173 is achieved by the driver 171 pushing the movable block 172 to slide back and forth.

[0047] Furthermore, the movable plate 14 is L-shaped, the adhesive application assembly 16 is installed on the lower upper end face of the movable plate 14, the cutting assembly 17 is installed on the side of the movable plate 14, and the movable block 172 in the cutting assembly 17 contacts the lower end face of the fixing plate 161 of the adhesive application assembly 16. The cutting assembly 17 provides support for the adhesive application assembly 16, simplifying the structure.

[0048] In this embodiment of the utility model, the transverse moving component 13 is arranged in an "L" shape and includes a drive motor 131, a synchronous pulley assembly 132 and a lead screw pair 133. The drive motor 131 is installed close to the moving component 11 and is connected to one end of the synchronous pulley. The synchronous pulley is connected to the lead screw pair 133 across the fixed plate 12. The lead screw pair 133 is installed on the end face of the fixed plate 12.
