Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery processing, and in particular to a hot melt adhesive laminating device for new energy battery processing. Background Art

[0002] Hot melt adhesive is widely used in the production and processing of new energy batteries due to its advantages such as fast curing, solvent-free and environmentally friendly, reliable bonding, easy automation, good insulation, and excellent buffering and sealing performance.

[0003] At present, during the assembly and processing of battery packs, electrical connections usually use threaded connections to achieve rapid disassembly and assembly of modules. Compared with conventional welding, it is more convenient to replace faulty modules. However, battery packs usually apply hot melt glue to the wiring threads to achieve vibration and loosening resistance of the wiring parts during use. The packaging of the hot melt glue makes the subsequent disassembly and maintenance of the battery pack more difficult. In addition, the threaded wiring and hot melt glue bonding protection in the assembly and processing of battery packs are usually carried out separately, which will make the threaded wiring parts of the battery pack susceptible to contamination during transportation. At the same time, after the threaded wiring, the hot melt glue bonding protection can usually only be performed on the outside, and the inside of the thread is difficult to be penetrated by the glue. If the processing technology of applying glue first is adopted, it is easy to cause the glue to solidify prematurely, resulting in poor adhesion effect. Therefore, a hot melt glue bonding equipment for new energy battery processing is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to propose a hot melt adhesive bonding device for new energy battery processing.

Feed rails for distributing processed parts are provided on both the left and right sides of the limiting seat. The left feed rail is provided with an electrical connection assembly, and the right feed rail is provided with multiple positioning assemblies. Multiple adhesive laminating accessories are sleeved on the positioning assemblies. The adhesive laminating accessories consist of adhesive pads and stretchable overflow sleeves. An adjustment mechanical seat is hoisted in the processing table, and the adjustment mechanical seat is connected to two hydraulic push rods through a fixing plate. The hydraulic push rod is connected to a tightening motor through a fixing plate. The tightening motor is connected to a stretching assembly for pulling the stretching overflow rubber sleeve through a lifting push rod. A sealing glue pressure ring for limiting the pressure on the glue pad ring is provided below the stretching assembly. A plurality of elastic twisted edge poking feet arranged in a circumferential array are provided in the sealing glue pressure ring. A glue injection assembly is provided on the sealing glue pressure ring.

[0008] Preferably, a plurality of limit strips are fixedly connected to the outer wall of the positioning column, and the limit strips correspond one-to-one to the notch positions on the stretching overflow rubber sleeve. A plurality of feeding push rods are arranged outside the positioning column, and the feeding push rods are connected to a loading ring for pushing the glue-applying accessories upward, and the loading ring is slidably connected to the positioning column.

[0009] Preferably, the adjustment mechanical seat is connected to a rotating lifting mechanism via a retaining plate, and an output end of the rotating lifting mechanism is fixedly connected to an electromagnetic limiting seat for picking up the electrical foil.

[0010] Preferably, the output end of the hydraulic push rod is fixedly connected to the tightening motor via a fixing plate, and the output end of the tightening motor is fixedly connected to the tightening sleeve via a lifting push rod.

[0011] Preferably, the stretching assembly includes a stretching seat fixed on the output end of the lifting push rod, and the side wall of the stretching seat is connected to a plurality of electrically controlled rotating seats arranged in an array, and the electrically controlled rotating seat is rotatably connected to a plurality of stretching hooks through a pin shaft.

[0012] Preferably, the compensation component includes a spring compensation rod slidably arranged on the tightening sleeve, the bottom end of the spring compensation rod is fixedly connected to a limiting magnetic block, and the inner side wall of the tightening sleeve is adapted to the outer side wall of the wiring thread sleeve.

[0013] Preferably, the glue injection assembly includes a glue storage container fixed on a fixed plate, the glue storage container is connected to the bottom of the glue sealing pressure ring through a glue injection gun mechanism, the bottom end of the tightening sleeve is connected to the glue sealing pressure ring through multiple telescopic rods, the inner wall of the glue sealing pressure ring is arranged in a ladder shape, the glue sealing pressure ring is fixedly connected to the elastic twisted edge poking pin, and the elastic twisted edge poking pin is arranged inclined toward the axis of the glue sealing pressure ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution uses adhesive fittings to allow the stretched adhesive sleeve and the extruded hot melt adhesive to fuse together during electrical connection. During maintenance, the adhesive layer can be removed by peeling it off as a whole. Compared with traditional thread glue that requires solvent cleaning, this solution is more convenient. When removing, simply loosen the thread sleeve in reverse to drive the adhesive out, preserving the integrity of the thread.

[0015] 2.

[0016] 3. This solution uses the setting of a stretchable overflow sleeve to generate radial extrusion force after being compressed, thereby increasing the friction resistance of the thread. At the same time, the hot melt adhesive squeezed out of the stretchable overflow sleeve forms a polymer adhesion layer after solidification, which resists vibration displacement, realizes a double anti-loosening design, and ensures long-term stability.

[0022] Example, see Figures 1 to 11A hot melt adhesive bonding device for processing new energy batteries includes a processing table 1 and a limiting seat 2 for placing a standard single battery 3. Feeding guides 4 for distributing processing parts are provided on both the left and right sides of the limiting seat 2. An electrical connection component is provided on the left feeding guide 4, and a plurality of positioning components are provided on the right feeding guide 4. A plurality of gluing accessories are sleeved on the positioning components. The gluing accessories are composed of a gluing ring 12 and a stretching overflow sleeve 13. Furthermore, the electrical connection assembly is composed of multiple electrical foils 6 and multiple wiring threaded sleeves 7. The inner side wall of the feeding guide rail 4 is slidably connected to the feeding seat 5. Multiple electrical foils 6 and wiring threaded sleeves 7 are positioned and placed on the feeding seat 5 on the left. The positioning assembly includes a positioning column 8 fixed on the feeding seat 5 on the right. The top of the stretching overflow glue sleeve 13 is arranged in a multi-notch shape. The bottom end of the glue pad ring 12 is provided with multiple overflow glue holes for communicating with the internal cavity of the glue pad ring 12 and the stretching overflow glue sleeve 13. The stretching overflow glue sleeve 13 is provided with multiple penetration micropores. A plurality of limiting strips 9 are fixedly connected to the outer side wall of the positioning column 8. The limiting strips 9 correspond one-to-one to the notch positions on the stretching overflow glue sleeve 13. A plurality of feeding push rods 10 are arranged outside the positioning column 8. The feeding push rod 10 is connected to a loading ring 11 for pushing the glue accessories upward, and the loading ring 11 is slidably connected to the positioning column 8. It should be noted that the electrical foil 6 is nickel-plated during the production process to ensure that the electrical foil 6 and the wiring threaded sleeve 7 can be picked up by magnetic suction during the subsequent processing. The glue ring 12 in the glue fitting is made of soft rubber material, and the stretchable glue sleeve 13 is made of stretchable film material. Before feeding the glue ring 12 and the stretchable glue sleeve 13, the notch on the stretchable glue sleeve 13 is aligned with the limit strip 9 on the positioning column 8. Multiple glue fittings are stacked in sequence to facilitate the removal of the glue fittings during the subsequent glue processing. An adjustment mechanical seat 14 is hoisted in the processing table 1. The adjustment mechanical seat 14 is connected to two hydraulic push rods 16 through a fixing plate 15. The hydraulic push rods 16 are connected to a tightening motor 17 through a fixing plate. The tightening motor 17 is connected to a stretching assembly for pulling the stretched rubber sleeve 13 through a lifting push rod 18. Furthermore, the adjustment mechanical seat 14 is connected to a rotating lifting mechanism through a retaining plate 15, and the output end of the rotating lifting mechanism is fixedly connected to an electromagnetic limit seat 29 for picking up the electrical foil 6. The output end of the hydraulic push rod 16 is fixedly connected to the tightening motor 17 through a fixed plate, and the output end of the tightening motor 17 is fixedly connected to the tightening sleeve 19 through a lifting push rod 18. The stretching assembly includes a stretching seat 20 fixed to the output end of the lifting push rod 18. The side wall of the stretching seat 20 is connected to a plurality of electrically controlled rotating seats 21 arranged in an array. The electrically controlled rotating seat 21 is rotatably connected to a plurality of stretching hooks 22 through a pin shaft. It should be noted that: when electrically connecting and assembling adjacent standard single cells 3, the rotating lifting mechanism under the retaining plate 15 is used to drive the electrical foil 6 to move and deflect, so that the inner walls of both ends of the electrical foil 6 are respectively sleeved on the poles of the adjacent standard single cells 3, and then the position of the tightening sleeve 19 is adjusted by the hydraulic push rod 16 so that the axis of the tightening sleeve 19 and the axis of the pole are located on the same vertical axis, and then the lifting push rod 18 is used to push the stretching seat 20 downward, so that the glue pad ring 12 and the stretching overflow rubber sleeve 13 are sleeved on the outer wall of the pole, and then the mechanical seat 14 is adjusted to make the two tightening sleeves 19 move at the same time. The elastic edge poking feet 26 in the sealing glue pressing ring 25 are pressed tightly against the glue pad ring 12. As the elastic edge poking feet 26 continue to press against the glue pad ring 12, the elastic edge poking feet 26 will be elastically deformed, and the bottom ends thereof will be offset toward the inclined part of the axis during the deformation process, causing the glue pad ring 12 to be pulled and wrinkled, thereby opening the glue overflow hole at the bottom of the glue pad ring 12. Subsequently, the hot melt glue in the glue storage container 27 is injected into the sealing glue pressing ring 25 through the glue injection gun mechanism 28. The hot melt glue injection process is a prior art and will not be described in detail here. Based on the above advantages, as the hot melt adhesive is continuously injected, the internal cavities of the adhesive pad ring 12 and the stretching overflow adhesive sleeve 13 will be filled with hot melt adhesive, making it easier to subsequently adhere the hot melt adhesive to the inner wall of the wiring thread sleeve 7; A sealing ring 25 for pressing the adhesive pad 12 is provided below the stretching assembly. A plurality of elastic twisted edge protrusions 26 arranged in a circumferential array are provided in the sealing ring 25. A glue injection assembly is provided on the sealing ring 25. The fixed end of the lifting push rod 18 is connected to a tightening sleeve 19 through a plurality of fixing rods. A plurality of compensation components are provided in the tightening sleeve 19. Furthermore, the compensation component includes a spring compensation rod 23 slidably arranged on the tightening sleeve 19, the bottom end of the spring compensation rod 23 is fixedly connected to the limit magnetic block 24, the inner side wall of the tightening sleeve 19 is adapted to the outer side wall of the wiring threaded sleeve 7, and the glue injection component includes a glue storage container 27 fixed on the fixed plate, the glue storage container 27 is connected to the bottom of the sealing glue pressure ring 25 through the glue injection gun mechanism 28, the bottom end of the tightening sleeve 19 is connected to the sealing glue pressure ring 25 through a plurality of telescopic rods, the inner wall of the sealing glue pressure ring 25 is arranged in a ladder shape, the sealing glue pressure ring 25 is fixedly connected to the elastic twisted edge poking foot 26, and the elastic twisted edge poking foot 26 is inclined toward the axis of the sealing glue pressure ring 25; It should be noted that: the lifting push rod 18 is used to move up to drive the stretching seat 20 to move up, and then the stretching hook 22 is moved up to stretch the stretching overflow rubber sleeve 13. After the stretching overflow rubber sleeve 13 is stretched, the permeable micropores thereon will be opened, causing the hot melt adhesive in the internal cavity of the stretching overflow rubber sleeve 13 to slightly seep out, and then the tightening motor 17 is used to drive the tightening sleeve 19 to rotate, so that the wiring thread sleeve 7 rotates on the threaded pole of the standard single battery 3, so that the wiring thread sleeve 7 is continuously tightened, and the spring compensation rod 23 compensates for the displacement of the wiring thread sleeve 7 in this process, ensuring that the tightening sleeve 19 tightens the wiring thread sleeve 7 without deviation. In the process of tightening the wiring thread sleeve 7, the hot melt adhesive in the internal cavity of the stretching overflow rubber sleeve 13 is stretched. The glue will be continuously pressed out, so that the inside of the threaded connection will also be adhered with hot melt glue, and the stretched glue sleeve 13 is pressed tightly by the thread, so that the threaded connection between the wiring thread sleeve 7 and the battery terminal is not only bound by the adhesion of the hot melt glue, but also by the extrusion friction of the stretched glue sleeve 13, so that the connection of the wiring thread sleeve 7 to the inner wall is strengthened, thereby preventing the battery from loosening during use. At the same time, the stretched glue sleeve 13 and the hot melt glue pressed out therein are close to an integrated state. If the battery module in the battery pack is subsequently repaired and replaced, the integrated state of the stretched glue sleeve 13 and the hot melt glue will make the removal of the threaded connection part more convenient, and then the sealing glue pressure ring 25 moves upward to apply a uniform layer of hot melt glue on the battery terminal; The benefits mentioned above are: This allows the battery pack's electrical connection assembly and post-wiring gluing and packaging to be performed simultaneously, avoiding the situation where there is no strong internal binding due to electrical assembly first and then gluing, and the situation where glue solidifies and the bonding effect is poor due to gluing first and then electrical organization. Synchronous processing greatly improves the overall processing efficiency of the battery pack; When the present invention is in use, the standard single battery 3 that needs to be electrically assembled is placed in the limiting seat 2 in sequence, and then the two feeding seats 5 for conveying the electrical foil 6, the wiring thread sleeve 7 and the glue-applying accessories are moved to the set position in the processing table 1 through the feeding guide 4 and stopped. Then the mechanical seat 14 is controlled to move to the left, and the wiring thread sleeve 7 is magnetically picked up by the multiple limiting magnetic blocks 24 in the tightening sleeve 19. At the same time, the electrical foil 6 is magnetically picked up by the electromagnetic limiting seat 29. Then the mechanical seat 14 is moved to the right, and the wiring thread sleeve 7 is magnetically picked up by the electromagnetic limiting seat 29. The lifting push rod 18 moves the stretching seat 20 to the top of the positioning column 8, and then synchronously controls the electric control rotating seat 21 on the stretching seat 20 to rotate, so that the electric control rotating seat 21 drives the stretching hook 22 to rotate. The rotation of the stretching hook 22 will hook the non-notched parts of the top of the stretching overflow rubber sleeve 13 one by one. Then the lifting push rod 18 drives the stretching seat 20 to move upward to complete the material collection of the glue-attached accessories. After the material is collected, the feeding push rod 10 will push the feeding ring 11, so that the top stretching overflow rubber sleeve 13 moves to the set height, which is convenient for the next material collection. After the material is taken, when the adjacent standard single cells 3 are electrically connected and assembled, the rotating lifting mechanism under the retaining plate 15 is used to drive the electrical foil 6 to move and deflect, so that the inner walls of the two ends of the electrical foil 6 are respectively sleeved on the poles of the adjacent standard single cells 3, and then the position of the tightening sleeve 19 is adjusted by the hydraulic push rod 16, so that the axis of the tightening sleeve 19 and the axis of the pole are located on the same vertical axis, and then the lifting push rod 18 is used to push the stretching seat 20 downward, so that the glue pad ring 12 and the stretching overflow sleeve 13 are sleeved on the outer wall of the pole, and then the mechanical seat 14 is adjusted to make the two tightening sleeves 19 move downward synchronously, thereby driving the sealing pressure ring 25 to move downward, so that the multiple sealing pressure rings 25 are located in the sealing pressure ring 25. The elastic twisted edge protruding foot 26 is pressed tightly against the adhesive pad ring 12. As the elastic twisted edge protruding foot 26 continues to press tightly against the adhesive pad ring 12, the elastic twisted edge protruding foot 26 will undergo elastic deformation, and its bottom end will deviate toward the axial inclination during the deformation process, causing the adhesive pad ring 12 to be pulled and wrinkled, thereby opening the glue overflow hole at the bottom of the adhesive pad ring 12. Subsequently, the hot melt adhesive in the glue storage container 27 is injected into the sealing glue pressure ring 25 through the glue injection gun mechanism 28. The hot melt adhesive injection process is a prior art and will not be described in detail here. As the hot melt adhesive is continuously injected, the internal cavities of the adhesive pad ring 12 and the stretched glue overflow sleeve 13 will be filled with hot melt adhesive, which is convenient for the subsequent adhesion of the hot melt adhesive to the inner wall of the wiring threaded sleeve 7. When making electrical connections and assembling between battery packs, first use the lifting push rod 18 to move up to drive the stretching seat 20 to move up, and then move the stretching hook 22 up to stretch the stretching overflow glue sleeve 13. After the stretching overflow glue sleeve 13 is stretched, the permeable micropores on it will be opened, so that the hot melt glue in the internal cavity of the stretching overflow glue sleeve 13 will seep out slightly, and then use the tightening motor 17 to drive the tightening sleeve 19 to rotate, so that the wiring thread sleeve 7 rotates on the threaded pole of the standard single battery 3, so that the wiring thread sleeve 7 is continuously tightened, and the spring compensation rod 23 compensates for the displacement of the wiring thread sleeve 7 in this process to ensure that the tightening sleeve 19 tightens the wiring thread sleeve 7 without deviation. In the process of tightening the wiring thread sleeve 7, the hot melt glue in the internal cavity of the stretching overflow glue sleeve 13 will be continuously squeezed out, so that the inside of the threaded wiring will also be fitted with hot melt glue, and the stretching overflow glue sleeve 13 is pressed by the thread, so that the wiring thread sleeve The threaded connection between the threaded sleeve 7 and the battery terminal is bound by the adhesion of the hot melt adhesive and the extrusion friction of the stretched glue sleeve 13, so that the connection of the wiring threaded sleeve 7 to the inner wall is strengthened to prevent loosening during the use of the battery. At the same time, the stretched glue sleeve 13 and the hot melt adhesive squeezed out of it are close to an integrated state. If the battery module in the battery pack is subsequently repaired and replaced, the integrated state of the stretched glue sleeve 13 and the hot melt adhesive will make the removal of the threaded wiring part more convenient. Subsequently, the upward movement of the sealing pressure ring 25 will apply a uniform layer of hot melt adhesive to the battery terminal, so that the electrical connection assembly of the battery pack and the glue packaging after wiring can be carried out simultaneously, avoiding the situation where there is no strong internal constraint due to electrical assembly first and then glue, and the situation where the glue solidifies and the adhesion effect is poor due to electrical organization after glue. The synchronous processing greatly improves the overall processing efficiency of the battery pack.
