Description

Technical Field

[0001] This invention relates to the field of battery tab production equipment, and particularly to a battery tab melt adhesive bonding device. Background Technology

[0002] In battery manufacturing, battery tabs require double-sided lamination to facilitate subsequent battery assembly and welding processes. Existing tab lamination equipment typically employs multiple robotic arms working collaboratively, with various actuators performing actions such as feeding, positioning, lamination, and pressing. While this multi-robotics approach accomplishes the lamination task, the overall equipment structure is complex, requiring multiple independent drive and control systems, leading to high manufacturing costs. Furthermore, the coordinated control of multiple robotic arms places high demands on the control system, resulting in significant maintenance workload and costs. Therefore, we aim to develop a rapid lamination device to improve operational efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a battery tab melt adhesive application device, which solves the technical problems of existing mechanical double-sided tab film application requiring multiple robotic arms to work together, resulting in high equipment costs and high maintenance.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A battery tab hot glue bonding device includes a base plate and a back box. The back box is provided on the base plate, and a double-sided feeding mechanism and a ramp platform are provided on the base plate. A strip-shaped through groove, an oblique through groove and an arc-shaped through groove are respectively provided on the back box. The strip-shaped through groove and the oblique through groove intersect and connect at one end. An arc-shaped through groove is provided on the strip-shaped through groove near the connecting end. A semi-circular slider assembly a is slidably provided in the strip-shaped through groove, and a semi-circular slider assembly b is slidably provided in the oblique through groove.

[0006] The back box contains a rotary pressure roller assembly, which is rotatably mounted on the back box and can move in an arc shape around the center of the arc-shaped through groove. The back box also contains a lead screw module motor and a servo motor meshing assembly. A lever is installed on the moving block of the lead screw module motor. The lever gradually approaches the end where the strip through groove and the inclined through groove intersect and connects, while pushing the semi-circular slider assembly a and the semi-circular slider assembly b until they are magnetically attracted together. The semi-circular slider assembly a meshes with the servo motor meshing assembly, driving the semi-circular slider assembly a and the semi-circular slider assembly b to rotate. At the same time, the semi-circular slider assembly a and the semi-circular slider assembly b move the rotary pressure roller assembly to press the material. The back box contains a control box, which controls the operation of the lead screw module motor and the servo motor meshing assembly.

[0007] Preferably, the double-sided feeding mechanism includes a vertical pole, feeding rack a and feeding rack b, feeding rack a and feeding rack b are installed opposite each other on one side of the vertical pole, feeding rack a and feeding rack b are close to semi-circular slider assembly a and semi-circular slider assembly b, and feeding rack a and feeding rack b have the same structure.

[0008] Preferably, the feeding rack a includes a material rack and a rotating roller a, with the rotating roller a mounted on the material rack and both ends of the rotating roller a mounted on the material rack by screws.

[0009] Preferably, the ramp platform includes a support frame a, a support frame b, a rotating roller b, and a conveyor belt. The rotating roller b is installed on both the support frame a and the support frame b, and the conveyor belt is fitted on the rotating roller b. The height of the support frame b is higher than that of the support frame a.

[0010] Preferably, the semi-circular slider assembly a includes a round rod a, a semi-circular rod a, a gear a, and a semi-circular sleeve a. One end of the round rod a is provided with a semi-circular rod a, the other end of the round rod a is provided with a gear a, the semi-circular sleeve a is fitted on the semi-circular rod a, and a magnet a is embedded in the semi-circular rod a.

[0011] Preferably, the semicircular slider assembly b includes a semicircular rod b, a protrusion and a semicircular sleeve b. The protrusion is provided at one end of the semicircular rod b, and the protrusion is close to the circular rod a. The semicircular sleeve b is fitted on the semicircular rod b, and a magnet b is embedded in the semicircular rod b. The magnet a and the magnet b are attracted to each other by opposite poles.

[0012] Preferably, the rotating pressure roller assembly includes a sleeve rod, a counterweight plate, an inclined plate, a bearing a, and a flattening roller. The sleeve rod is installed inside the back box, the inclined plate is sleeved on the sleeve rod and rotates on the sleeve rod through the bearing a, the counterweight plate is provided below the inclined plate, and the flattening roller is installed on the inclined plate.

[0013] Preferably, the servo motor meshing assembly includes a servo motor body and a gear b, with the gear b disposed on the rotating shaft of the servo motor body.

[0014] In summary, the present invention has the following beneficial effects:

[0015] The device uses the cross arrangement of strip-shaped and oblique through-slots to enable two semi-circular slider assemblies to slide synchronously along different trajectories under the same drive source, and automatically combine into a cylinder at the end of the stroke by the attraction of opposite magnetic poles, without the need for additional alignment mechanisms, thus reducing the number of actuators and control logic.

[0016] The lead screw module motor drives the lever to simultaneously push the two semi-circular slider assemblies to move. After they are engaged, the servo motor meshing assembly automatically drives them to rotate. At the same time, the semi-circular slider assembly moves the counterweight plate during rotation, causing the flattening roller to press down on the material. This achieves continuous and automated pushing, engaging, rotating and pressing actions. The actions are closely connected, reducing waiting time and auxiliary actions, and significantly increasing the number of coatings per unit time.

[0017] In the double-sided feeding mechanism, feeding racks a and b, which are installed opposite to each other, output two layers of film-coated tape respectively. The adhesive surfaces are opposite to each other. The two semi-circular slider assemblies clamp the battery tabs between the two layers of tape while pulling the tape, thus completing the double-sided coating in one go.

[0018] The rotating pressure roller assembly applies pressure synchronously during the conveyor belt's movement, resulting in a more secure application and eliminating the need for a separate subsequent pressing process. Semicircular sleeves A and B are detachably mounted on the semicircular rod and can be removed along with the finished product for vacuum packaging after winding, facilitating material transfer and storage. The inclined platform utilizes a conveyor belt structure with one end higher than the other, allowing the battery tabs to slide naturally into the application area under gravity, reducing the need for additional feeding mechanisms and improving overall work efficiency.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0028] Example

[0029] like Figure 1As shown, a battery tab bonding device includes a base plate 1 and a back box 2. The base plate 1 serves as the base of the entire device, and the back box 2 is fixedly mounted on the base plate 1. The base plate 1 is also provided with a double-sided feeding mechanism 3 and a ramp platform 4. The double-sided feeding mechanism 3 is used to place the upper and lower layers of film-coated tape, and the ramp platform 4 is used to prevent the tabs from falling after the lower layer of film-coated tape is placed.

[0030] like Figure 1 , Figure 3 , Figure 4 As shown, a strip-shaped through groove 5, an oblique through groove 6, and an arc-shaped through groove 7 are respectively formed on the side wall of the back box 2. The strip-shaped through groove 5 extends horizontally to the right, and the oblique through groove 6 is set at an angle relative to the strip-shaped through groove 5. Finally, the strip-shaped through groove 5 and the oblique through groove 6 intersect and connect with each other. An arc-shaped through groove 7 is provided on the strip-shaped through groove 5 near the connecting end. A semi-circular slider assembly a8 is slidably installed in the strip-shaped through groove 5, and a semi-circular slider assembly b9 is slidably installed in the oblique through groove 6. The semi-circular slider assembly a8 and the semi-circular slider assembly b9 can slide in their respective through grooves, and they can approach and contact each other when they slide to the connecting end.

[0031] The back box 2 is equipped with a rotary pressure roller assembly 10, which is rotatably mounted on the inner wall of the back box 2. The rotary pressure roller assembly 10 can move in an arc around the center of the arc-shaped through groove 7 within the trajectory range of the arc-shaped through groove 7, thereby realizing the pressing action of the coating material.

[0032] like Figure 4 , Figure 5 , Figure 6 As shown, the back box 2 also houses a lead screw module motor 11 and a meshing motor assembly 12. A lever 13 is fixedly connected to the moving block of the lead screw module motor 11. When the lead screw module motor 11 starts, the moving block drives the lever 13 to gradually approach the end where the strip groove 5 and the oblique groove 6 intersect and connect. During the movement, the lever 13 simultaneously abuts against the semi-circular slider assembly a8 and the semi-circular slider assembly b9 and pushes them to slide towards the connecting end until the semi-circular slider assembly a8 and the semi-circular slider assembly b9 are magnetically attracted together. At this time, the semi-circular slider assembly a8 and the meshing motor assembly 12 form a meshing engagement. After the meshing motor assembly 12 starts, it drives the semi-circular slider assembly a8 and the semi-circular slider assembly b9 to rotate together. At the same time, the semi-circular slider assembly a8 and the semi-circular slider assembly b9 will actuate the rotating pressure roller assembly 10 during rotation, causing the rotating pressure roller assembly 10 to swing downward and press the material passing through it. The back box 2 is also equipped with a control box 14, which is electrically connected to the lead screw module motor 11 and the meshing motor assembly 12 respectively, and is used to control the start-stop and action sequence of the two.

[0033] like Figure 1 , Figure 2As shown, the specific structure of the double-sided feeding mechanism 3 includes a vertical rod 30, a feeding rack a31, and a feeding rack b32. Feeding racks a31 and b32 are mounted opposite each other on the same side of the vertical rod 30, and their positions are near the initial positions of the semi-circular slider assemblies a8 and b9. Feeding racks a31 and b32 have identical structures to facilitate the loading of the upper and lower coated adhesive tapes respectively. The two feeding racks are arranged opposite each other so that the adhesive surfaces of the two layers of tape face each other.

[0034] Furthermore, the feeding rack a31 includes a rack 34 and a rotating roller a35. The rotating roller a35 is mounted on the rack 34, and both ends of the rotating roller a35 are fixed between the two side plates of the rack 34 by screws. The coated tape roll is sleeved on the rotating roller a35.

[0035] like Figure 1 , Figure 3 As shown, the ramp platform 4 includes a support frame a40, a support frame b41, rotating rollers b42, and a conveyor belt 43. Rotating rollers b42 are respectively installed on support frame a40 and support frame b41, and the conveyor belt 43 is fitted onto the two rotating rollers b42 to form a conveying plane. The height of support frame b41 is higher than that of support frame a40, causing the conveyor belt 43 to be in an inclined state. This facilitates the sliding of the battery tabs along the ramp platform into the bonding area under the assistance of gravity. Alternatively, a simple ramp platform can achieve the same effect.

[0036] like Figure 7 As shown, the semi-circular slider assembly a8 includes a round rod a81, a semi-circular rod a82, a gear a83, and a semi-circular sleeve a84. One end of the round rod a81 is coaxially connected to the semi-circular rod a82, and the cross-section of the semi-circular rod a82 is semi-circular. The gear a83 is fixedly mounted on the other end of the round rod a81. The semi-circular sleeve a84 is fitted around the semi-circular rod a82, and the shape of the semi-circular sleeve a84 matches that of the semi-circular rod a82. A magnet a85 is embedded inside the semi-circular rod a82.

[0037] The semi-circular slider assembly b9 includes a semi-circular rod b91, a protrusion 92, and a semi-circular sleeve b93. One end of the semi-circular rod b91 has the protrusion 92 to prevent it from dislodging from the inclined through groove 6. The protrusion 92 is positioned close to one end of the circular rod a81. The semi-circular sleeve b93 is fitted over the semi-circular rod b91, and a magnet b94 is embedded inside the semi-circular rod b91. Magnet a85 and magnet b94 are configured with opposite magnetic poles facing each other, generating a magnetic force that attracts them when they are close together. When the semi-circular slider assemblies a8 and b99 are moved to the connecting end by the lever 13, magnet a85 and magnet b94 are attracted, combining the two semi-circular slider assemblies into a complete cylindrical structure.

[0038] like Figure 4 , Figure 6As shown, the rotary pressure roller assembly 10 includes a sleeve rod 20, a counterweight plate 21, an inclined plate 22, a bearing a23, and a flattening roller 24. The sleeve rod 20 is fixedly installed inside the back box 2. The inclined plate 22 is sleeved on the sleeve rod 20 and rotates relative to the sleeve rod 20 through the bearing a23. The counterweight plate 21 is fixedly connected to the lower part of the inclined plate 22. The counterweight plate 21 is used to contact the semi-circular slider assembly a8 and transmit power. The flattening roller 24 is installed at the upper end of the inclined plate 22. The flattening roller 24 rises and falls with the swing of the inclined plate 22 to press the material.

[0039] The servo motor engagement assembly 12 includes a servo motor body 25 and a gear b26, with the gear b26 fixedly mounted on the rotation shaft of the servo motor body 25. When the semi-circular slider assembly a8 moves into position, the gear a83 meshes with the gear b26, and the power of the servo motor body 25 is transmitted to the gear a83 through the gear b26, thereby driving the semi-circular slider assembly a8 and the semi-circular slider assembly b9 that it engages with to rotate together.

[0040] Working principle of the invention:

[0041] Workers install coated adhesive tape on the feeding racks a31 and b32 of the double-sided feeding mechanism 3, with the adhesive surfaces facing each other. They separate the semi-circular slider assemblies a8 and b9, and move them closer to the double-sided feeding mechanism 3. A semi-circular sleeve a84 is fitted onto the semi-circular rod a82, and a semi-circular sleeve b93 is fitted onto the semi-circular rod b91. One end of the coated adhesive tape on feeding rack a31 is attached to the semi-circular sleeve a84, and one end of the coated adhesive tape on feeding rack b32 is also attached to the semi-circular sleeve b93. Simultaneously, the lever 13 on the screw module motor 11 pushes the semi-circular slider assemblies a8 and b9 to the right. (See reference...) Figure 1 and Figure 6 The external robotic arm regularly places the cut battery tabs on the film-coated tape of the feeding rack b32. As it moves to the right, the semi-circular slider assembly a8 and the semi-circular slider assembly b9 eventually stick together. At the same time, the semi-circular slider assembly a8 engages with the servo motor engagement assembly 12.

[0042] Servo motor engagement assembly 12 drives semi-circular slider assembly a8 and semi-circular slider assembly b9 to rotate. Semi-circular slider assembly a8 moves counterweight plate 21, causing flattening roller 24 to press down on the material. Rotating pressure roller assembly 10 presses the material, which is then wound up by semi-circular slider assembly a8 and semi-circular slider assembly b9. Semi-circular sleeve a84 and semi-circular sleeve b93 can be removed, and the wound battery tabs are vacuum-packed with film.

[0043] The control box 14 controls the coordinated operation of the lead screw module motor 11 and the meshing motor assembly 12 according to the preset program, so as to realize the automatic cycle of each action.
