[0053] In the glue sticking equipment, the glue preparation device 1 obtains the glue tape for standby use. After the glue preparation device 1 obtains the required length of the glue tape, the moving device drives the glue preparation device 1 to move in the direction away from the glue cutting blade 56, and then the glue cutting power part 55 drives the glue cutting blade 56 to approach the glue tape to cut the glue tape, thereby completing the preparation of the glue tape of the required length. After the glue cutting is completed, the moving device drives the glue preparation device 1 to move in the direction close to the glue cutting blade 56 to restore it to its original position.

[0054] With such an arrangement, before the glue cutting blade 56 cuts the adhesive tape, the moving device 6 first drives the glue preparation device 1 to move away from the glue cutting blade 56, so that there is a certain distance between the glue preparation device 1 and the glue cutting blade 56, thereby preventing the glue cutting blade 56 from damaging the glue preparation device 1 when cutting the adhesive tape, thereby alleviating the technical problem in the prior art that the glue cutting device 5 in the glue laminating equipment is prone to damage the glue preparation device 1 during the process of cutting the adhesive tape on the glue preparation device 1.

[0055] Preferably, see Figure 7 and Figure 8 In this embodiment, the moving device 6 includes a moving motor 61 and a linear module 62 both installed on the fixed plate 2. The extension direction of the linear module 62 is perpendicular to the moving direction of the rubber cutting blade 56. The moving motor 61 drives the linear module 62, and the glue preparation device 1 is connected to the slider of the linear module 62.

[0056] In the initial position, see Fig. 9 At this time, the glue cutting device will not cut the glue paper on the glue preparation device; if you need to cut the glue paper on the glue preparation device, please refer to Fig.10 The mobile motor 61 drives the linear module 62 to move, so that the glue preparation device 1 slides along the extension direction of the linear module 62, so that the glue preparation device 1 moves relative to the rubber cutting blade 56 in a direction perpendicular to the moving direction of the rubber cutting blade 56, see Fig.10 , so that along the vertical direction, the highest point of the glue preparation device 1 is spaced from the glue cutting blade 56 by a lateral gap a to prevent the glue cutting blade 56 from damaging the glue preparation device 1 when cutting the adhesive tape.

[0057] Preferably, see Figure 3 , Figure 4 and Figure 5In this embodiment, the rubber cutting device 5 also includes a pressing mechanism arranged on the rubber cutting frame 51; the pressing mechanism includes a first pressing plate 52, a second pressing plate 54 and a pressing power member 53 installed on the rubber cutting frame 51, the first pressing plate 52 is arranged on the rubber cutting frame 51, the pressing power member 53 drives the second pressing plate 54, and the pressing power member 53 can drive the second pressing plate 54 to move toward or away from the first pressing plate 52, the second pressing plate 54 moves toward the first pressing plate 52 and can contact the first pressing plate 52, and the second pressing plate 54 moves toward the first pressing plate 52 and can form a gap between the first pressing plate 52 for the rubber paper to pass through.

[0058] With such an arrangement, the adhesive tape passes through the gap between the first pressing plate 52 and the second pressing plate 54 in the adhesive cutting device 5 and reaches the adhesive preparation device 1 .

[0059] When the adhesive tape is being conveyed, there is a gap between the first pressing plate 52 and the second pressing plate 54 to facilitate the conveyance of the adhesive tape; when the adhesive tape needs to be cut, first the pressing power member 53 drives the second pressing plate 54 to move toward the first pressing plate 52 so that the second pressing plate 54 contacts the first pressing plate 52, thereby pressing the adhesive tape between the second pressing plate 54 and the first pressing plate 52 to facilitate the cutting of the adhesive tape, and then the cutting power member 55 drives the cutting blade 56 to approach the adhesive tape to cut the adhesive tape.

[0060] Preferably, see Figure 6 , Figure 7 and Figure 8 In this embodiment, the glue preparation device 1 includes a glue preparation mechanism and a glue pressing mechanism; the glue preparation mechanism includes a glue preparation roller 11 provided with a vacuum adsorption hole and a first rotation driving component 12 capable of driving the glue preparation roller 11 to rotate; the glue pressing mechanism includes a glue pressing piece 13, a glue pressing frame 14 rotatably connected to the roller shaft of the glue preparation roller 11, and a second rotation driving component 15 capable of driving the glue pressing frame 14 to rotate relative to the roller shaft of the glue preparation roller 11. The glue pressing piece 13 is connected to the glue pressing frame 14 and can move toward or away from the roller surface of the glue preparation roller 11. When the glue pressing piece 13 moves toward the roller surface of the glue preparation roller 11, it can contact the roller surface of the glue preparation roller 11. When the glue pressing piece 13 moves away from the roller surface of the glue preparation roller 11, there can be a gap between the roller surface of the glue preparation roller 11 and the glue pressing piece 13.

[0061] When the glue preparation device 1 is used, first, the head end of the adhesive paper is set on the roller surface of the glue preparation roller 11, and the second rotary drive component 15 drives the glue pressing frame 14 to rotate, so as to drive the glue pressing piece 13 to rotate to the head end of the adhesive paper, and then the glue pressing piece 13 moves toward the roller surface close to the glue preparation roller 11 to contact the roller surface of the glue preparation roller 11, so that the head end of the adhesive paper is pressed and fixed between the roller surface of the glue preparation roller 11 and the glue pressing piece 13; then the first rotary drive component 12 drives the glue preparation roller 11 to rotate a certain angle in the first direction, and at the same time, the second rotary drive component 15 drives the glue pressing frame 14 to rotate synchronously in the first direction relative to the roller shaft of the glue preparation roller 11, so that on the basis of the head end of the adhesive paper being pressed and fixed between the roller surface of the glue preparation roller 11 and the glue pressing piece 13, the adhesive paper can rotate in the first direction with the roller surface of the glue preparation roller 11, so as to pull the adhesive paper to a certain length, and cooperate with the vacuum adsorption hole on the glue preparation roller 11 to make the adhesive paper adsorbed on the roller surface of the glue preparation roller 11, and the glue preparation of a certain length of adhesive paper is completed.

[0062] If the length of the adhesive tape required for the preparation is long, the adhesive tape can be pressed and fed in multiple times according to the length of the preparation. Specifically, after the adhesive tape is pulled to a certain length in the first direction, the preparation roller 11 and the adhesive pressing frame 14 stop rotating, and the adhesive pressing member 13 moves away from the roller surface of the preparation roller 11 so that there is a gap between the roller surface of the preparation roller 11, and then the adhesive pressing frame 14 is driven to rotate in the second direction by the second rotating drive component 15 to drive the adhesive pressing member 13 to rotate in the opposite direction to the original position, and then the adhesive pressing member 13 moves toward the roller surface close to the preparation roller 11 to contact the roller surface of the preparation roller 11, so that the middle part of the adhesive tape is pressed and fixed between the roller surface of the preparation roller 11 and the adhesive pressing member. Then, the first rotary drive component 12 continues to drive the rubber preparation roller 11 to rotate a certain angle in the first direction, and at the same time, the second rotary drive component 15 drives the glue pressing frame 14 to rotate synchronously in the first direction relative to the roller shaft of the rubber preparation roller 11, so that the middle part of the rubber paper is pressed between the roller surface of the rubber preparation roller 11 and the glue pressing component 13, so that the rubber paper can continue to rotate in the first direction with the roller surface of the rubber preparation roller 11, so as to pull the rubber paper to a certain length, and the preparation of a certain length of rubber paper is completed for the second time (the second direction is opposite to the first direction).

[0063] The above steps can be repeated multiple times according to the required adhesive tape length until the required adhesive tape length is obtained.

[0064] With such a setting, the glue preparation device 1 can press-feed the glue tape for multiple times according to the required length of the glue tape to achieve glue preparation of any length, which greatly improves the glue sticking compatibility range of the gluing device and can be compatible with the client's ultra-large range of glue sticking length requirements, reduces the trouble of conversion and modification, improves the compatibility of the equipment and product competitiveness, and by pressing-feeding the glue tape for multiple times, the pulling tension of the glue tape is reduced, thereby reducing the deformation of the glue tape.

[0065] Preferably, in this embodiment, the glue preparation device 1 also includes a glue preparation rack, and the glue preparation roller 11 is rotatably connected to the glue preparation rack; the first rotation drive component 12 includes a first rotation motor and a first transmission unit, the first rotation motor is installed on the glue preparation rack, and the first rotation motor is driven and connected to the glue preparation roller 11 through the first transmission unit; the second rotation drive component 15 includes a second rotation motor and a second transmission unit, the second rotation motor is installed on the glue preparation rack, and the second rotation motor is driven and connected to the glue pressing rack 14 through the second transmission unit.

[0066] Optionally, the first transmission unit and the second transmission unit may be a chain drive, a belt drive, a gear drive or other structures.

[0067] Preferably, see Figure 7 In this embodiment, the glue pressing mechanism also includes a glue pressing cylinder 16, the cylinder barrel of the glue pressing cylinder 16 is installed on the glue pressing frame 14, and the glue pressing component 13 is connected to the piston rod of the glue pressing cylinder 16. The piston rod is retracted relative to the cylinder barrel, and can drive the glue pressing component 13 to move closer to or away from the roller surface of the backup rubber roller 11.

[0068] Preferably, see Figure 1 In this embodiment, the glue laminating equipment also includes a glue preparation tray 3 and a glue opening device 4 for pulling open the glue paper on the glue preparation tray 3. The glue preparation tray 3 and the glue opening device 4 are both arranged on the fixed plate 2; the glue paper on the glue preparation tray 3 can pass through the glue opening device 4 and the glue cutting device 5 in sequence and reach the glue preparation device 1.

[0069] That is, on the fixed plate 2, along the conveying direction of the adhesive tape, the adhesive preparation tray 3, the adhesive opening device 4, the adhesive cutting device 5 and the adhesive preparation device 1 are arranged in sequence.

[0070] With such an arrangement, in the gluing equipment, after the adhesive paper roll is placed on the preparation glue tray 3, the adhesive paper on the preparation glue tray 3 is pulled apart by the glue opening device 4 and cached for later use, thereby reducing the tension of glue pulling during preparation and alleviating deformation of the adhesive tape. The pulled adhesive paper passes through the glue cutting device 5 and reaches the preparation glue roller 11 of the preparation glue device 1.

[0071] Among them, after the head end of the adhesive tape passes through the glue cutting device 5 and is set on the roller surface of the preparation rubber roller 11, the second rotary drive component 15 drives the glue pressing frame 14 to rotate, so as to drive the glue pressing piece 13 to rotate to the glue cutting device 5, and then the glue pressing piece 13 moves toward the roller surface close to the preparation rubber roller 11 to contact the roller surface of the preparation rubber roller 11, so as to press the head end of the adhesive tape between the roller surface of the preparation rubber roller 11 and the glue pressing piece 13; then the first rotary drive component 12 drives the preparation rubber roller 11 to rotate a certain angle in the first direction, and at the same time, the second rotary drive component 15 drives the glue pressing frame 14 to rotate synchronously in the first direction relative to the roller shaft of the preparation rubber roller 11, so that the adhesive tape rotates with the roller surface of the preparation rubber roller 11 in the first direction, so as to pull the adhesive tape to a certain length, thereby completing the preparation of adhesive tape of a certain length.

[0072] If the required length of the adhesive tape is long, the adhesive tape can be pressed and fed several times according to the length of the adhesive tape until the required length of the adhesive tape is prepared. At this time, the tail end of the adhesive tape is located at the adhesive cutting device 5, and the tail end of the adhesive tape can be cut off by the adhesive cutting device 5, thus completing the preparation of the adhesive tape of the required length.

[0073] Preferably, see Figure 3 In this embodiment, the degumming device 4 includes a degumming plate 41 arranged on the fixed plate 2, a degumming slide rail 42 arranged on the degumming plate 41, a degumming slide seat 43 arranged on the degumming slide rail 42, and a degumming cylinder 44 installed on the degumming plate 41 and drivingly connected to the degumming slide seat 43. A degumming movable roller 45 is arranged on the degumming slide seat 43, and a plurality of degumming fixed rollers 46 are arranged on the degumming plate 41. The plurality of degumming fixed rollers 46 are distributed on both sides of the degumming slide rail 42; the degumming cylinder 44 can drive the degumming slide seat 43 to slide along the degumming slide rail 42, so as to drive the degumming movable roller 45 to slide relative to the degumming fixed roller 46, thereby achieving the purpose of degumming the glue paper on the spare glue plate 3.

[0074] Preferably, see Figure 1 and Figure 2 In this embodiment, the glue sticking equipment also includes a clamping device and a pole piece cutting device 7 capable of cutting the pole piece; the clamping device includes a first clamping component 81 and a second clamping component 82, both of which can clamp the pole piece, and the pole piece cutting device 7 is arranged between the first clamping component 81 and the second clamping component 82, and the first clamping component 81 can move toward or away from the second clamping component 82; after the pole piece is clamped by the first clamping component 81 and the second clamping component 82, the pole piece is parallel to the roller surface tangent of the glue preparation roller 11; wherein, the glue sticking equipment also includes a lifting drive component 9 installed on the fixed plate 2 and capable of driving the glue preparation device 1 to move toward or away from the pole piece.

[0075] With such an arrangement, after the electrode is transferred to the glue sticking equipment, the electrode is held by the first clamping assembly 81 and the second clamping assembly 82. At this time, the first clamping assembly 81 clamps the electrode near the front end, and the second clamping assembly 82 clamps the electrode near the rear end. The electrode is cut by the electrode cutting device 7. At this time, the electrode is cut into two sections, one section is clamped by the first clamping assembly 81, and the other section is clamped by the second clamping assembly 82. It should be noted that burrs will be generated after the electrode is cut, and the burrs can easily pierce the diaphragm and affect the quality of the battery cell. Therefore, the cut electrode needs to be separated for a distance and the two sections are connected with adhesive tape. Therefore, the glue sticking equipment of this embodiment drives a section of the electrode to move away from the second clamping assembly 82 through the first clamping assembly 81, so that the two sections of the electrode are separated by a distance.

[0076] At this time, the first rotating drive component 12 drives the preparation glue roller 11 to rotate, so that the adhesive paper on the preparation glue roller 11 rotates to a position corresponding to the pole piece, and then the lifting drive component 9 drives the preparation glue device 1 to move in the direction close to the pole piece, so that the preparation glue roller 11 contacts the pole piece, so that the adhesive paper on the preparation glue roller 11 is adhered to the pole piece, and in the process of conveying the pole piece, the first rotating drive component 12 drives the preparation glue roller 11 to rotate, so that the rotation direction of the preparation glue roller 11 is the same as the conveying direction of the pole piece, and the rotation linear speed of the preparation glue roller 11 is the same as the conveying of the pole piece, thereby realizing the flying of the adhesive paper onto the pole piece.

[0077] Among them, the glue preparation device 1 moves in the direction close to or away from the pole piece, which is realized by independent control of the lifting drive component 9, and the glue sticking position and the strength of the glue sticking can be conveniently adjusted at will. The glue sticking position is accurate, and the number of glue sticking bubbles is small, which greatly improves the glue sticking effect and improves the quality of the battery cell. In addition, during the transmission of the pole piece, the glue preparation roller 11 is driven to rotate actively by the first rotating drive component 12, which can realize the high-speed chasing function, improve the glue sticking efficiency, and well solve the defects of the prior art that the pole piece glue sticking quality is poor, the pole piece is easily stretched and deformed, and the battery quality is affected.

[0078] Optionally, the lifting drive assembly 9 is a lifting drive cylinder or a lifting drive module, etc., and its specific structure is not limited here, as long as it can drive the glue preparation device 1 to move linearly.

[0079] Preferably, see Figure 1 In this embodiment, the glue preparation tray 3, the glue opening device 4, the glue cutting device 5 and the glue preparation device 1 together form a glue sticking unit. The glue sticking equipment includes two glue sticking units, and the two glue sticking units are symmetrically arranged on both sides of the pole piece.

[0080] This arrangement enables the adhesive tape on the electrodes to be pasted evenly, resulting in fewer bubbles in the glue and a more ideal glue effect.
