[0001] This invention relates to the field of battery cell manufacturing equipment, and more particularly to a battery cell tab double-sided adhesive bonding equipment. Background Technology
[0002] During the production of prismatic battery cells, tab welding is required. Before welding, adhesive tape needs to be applied to the base of the tabs. Each prismatic battery cell has two tabs, each with two sides (top and bottom), resulting in four adhesive application points on both sides. Current technology uses a robotic arm to flip the cells, performing the adhesive application process twice. Each flip requires center calibration and positioning, which disrupts the production line rhythm and leads to a decrease in production capacity. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] like Figure 1-7 As shown, embodiments of the present invention include:
[0024] A double-sided adhesive bonding device for battery cell tabs includes a back plate 1, a tape feeding line 2, an outlet guide roller 3, a linear slide rail 4, a tape-taking gripper 5, a telescopic cylinder 6, a stop gripper 7, and a double-blade gripper 8. The back plate 1 is provided with two tape feeding lines 2, which converge to a pair of outlet guide rollers 3. A pair of linear slide rails 4 are mounted on the back plate 1 with the outlet guide rollers 3 as the origin. The tape-taking gripper 5 is provided at the outer end of the linear slide rail 4, facing the outlet guide rollers 3. The tape-taking gripper 5 is pulled by the telescopic cylinder 6 located at the inner end of the linear slide rail 4. The roller surface of the outlet guide roller 3 is matched with the stop gripper 7. The tape-taking gripper 5 and the stop gripper 7 form two tape channels in a straight line. The tape channels are perpendicularly matched on both sides of the double-blade gripper 8.
[0025] The stop pneumatic gripper 7 is vertically mounted on the edge of the back plate 1 via a stand 9. The stop pneumatic gripper 7 consists of a finger cylinder 10 and a U-shaped stop block 11. A damping strip 12 is embedded in the inner wall of the U-shaped stop block 11. The outlet guide roller 3 is matched inside the U-shaped stop block 11 and is parallel to the damping strip 12.
[0026] Furthermore, the outlet guide rollers 3 are respectively mounted on the two side walls of the finger cylinder 10, and the U-shaped stop blocks 11 correspond one-to-one with the outlet guide rollers 3 to form two opposite symmetrical stop mouths.
[0027] Furthermore, a pair of I-shaped sliders 13 and II-shaped sliders 14 are installed on the gripper 5. The I-shaped slider 13 is nested inside the II-shaped slider 14. The upper and lower ends of the I-shaped slider 13 are respectively provided with a pressure finger 15 and a roller shaft 16. The upper and lower ends of the II-shaped slider 14 are respectively provided with a roller shaft 17 and a pressure finger 18. The pressure finger 15 and roller shaft 17 are paired to form a gripping jaw 1, and the roller shaft 16 and pressure finger 18 are paired to form a gripping jaw 2.
[0028] Furthermore, two tape supply lines 2 are arranged on the back plate 1 in two directions, one above the other, with the routing directions of the tape supply lines 2 being symmetrical in opposite directions.
[0029] Furthermore, the dual-blade pneumatic gripper 8 is provided with a pair of cutting blades 19 arranged in opposite directions. The cutting edge of the cutting blade 19 is matched with a pair of grooved blade guards 20 arranged in opposite directions. The grooved blade guards 20 are bolted to the outside of the stand 9 and are arranged on the outside of the conveyor belt channel.
[0030] Furthermore, a verticality correction slider 21 is provided on the back of the stand 9, and a correction rail 22 is movably inserted into the verticality correction slider 21. The correction rail 22 and the double-blade pneumatic gripper 8 are mounted on the same sub-plate 23.
[0031] Furthermore, a sub-plate 24 is arranged parallel to the outer side of the back plate 1, and a cutter loading cylinder 25 is arranged vertically on the surface of the sub-plate 24. The cutter loading cylinder 25 is connected to the auxiliary plate 23.
[0032] Furthermore, a pair of vacuum adsorption platforms 26 are matched on the upper and lower sides of the tape channel, and each vacuum adsorption platform 26 is connected to two sets of two-axis linear modules 27. The two-axis linear modules 27 are respectively connected to the upper and lower sides of a double-sided adhesive applicator 28.
[0033] During the production of prismatic battery cells, tab welding is required. Before welding, adhesive tape needs to be applied to the base of the tabs. Each prismatic battery cell has two tabs, each with two sides (top and bottom), resulting in four adhesive application points on both sides. Current technology uses a robotic arm to flip the cells, performing the adhesive application process twice. Each flip requires center calibration and positioning, which disrupts the production line rhythm and leads to a decrease in production capacity.
[0034] To solve the problem of double-sided tape application at the base of the earpiece, this equipment has two tape feeding lines 2 arranged on the back plate 1. Each tape feeding line 2 has a tape reel, such as... Figure 5 As shown, the upper tape reel has the tacky side of the tape facing downwards, and after passing through the tension roller set, it is output to the upper exit guide roller 3; the lower tape reel has the tacky side of the tape facing upwards, and after passing through another tension roller set, it is output to the lower exit guide roller 3. The exit guide roller 3 has an anti-stick coating. Figure 1 In the middle, when the finger cylinder 10 drives the U-shaped stop block 11 to press against the outlet guide roller 3, the tape can be stopped, and the sticky side of the tape is pressed against the roller surface of the outlet guide roller 3.
[0035] The tape needs to be supplied in fixed lengths, the length of which is determined by... Figure 2 The telescopic cylinder 6 shown is used for control. The telescopic cylinder 6 pulls the linear slide rail 4, causing the gripper 5 to move horizontally, as shown. Figure 3 As shown, pressure finger 15 and roller 17 clamp the upper layer of tape, while pressure finger 2 18 and roller 2 16 clamp the lower layer of tape. The two tapes are pulled out synchronously. Afterwards, as... Figure 6 The vacuum adsorption stage 26 shown is loaded onto the tape channel, and simultaneously, the cutter loading cylinder 25 loads the double-blade gripper 8 onto the tape channel, as shown. Figure 4 The four blades shown cut the tape into segments, which are then picked up by the vacuum adsorption stage 26. The vacuum adsorption stage 26, along with the two-axis linear module 27, reaches the upper and lower sides of the double-sided tape applicator, where the tape is pressed into the designated position.
[0036] In summary, the present invention provides a double-sided adhesive bonding device for battery cell tabs. Because the pick-up gripper and the stop gripper are integrated with a double gripper, a dual-path adhesive tape channel can be constructed. The verticality correction slider is used to control the relative position of the double-blade gripper and the adhesive tape channel, thereby accurately and efficiently realizing the double-sided adhesive bonding process.
