Description

Technical Field

[0001] This utility model relates to the technical field of battery insertion equipment, and in particular to a high-speed battery insertion machine. Background Technology

[0002] Due to their excellent electrical characteristics, lithium batteries are widely used in various industries. With the increasing attention given to new energy vehicles by consumers, their market share is rapidly rising, and the closely related power lithium battery manufacturing industry is also developing rapidly. During the manufacturing process of power batteries, sealing pins are needed to seal the battery's electrolyte filling port. To improve production efficiency, pin-inserting devices have emerged on the market to automate the sealing process of the battery's electrolyte filling port.

[0003] In related technologies, after liquid injection and before formation, vacuuming is required to plug the injection hole with a rubber nail. During the formation process, the rubber nail needs to be pulled out. After formation, vacuuming and inserting rubber nails are required. Therefore, inserting and removing nails is a necessary process. However, in traditional production processes, nail insertion is usually completed by a single gripper, which results in low nail insertion efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a high-speed battery insertion machine, which aims to solve the problem of low insertion efficiency of battery filling holes.

[0005] To achieve the above objectives, the present invention proposes a high-speed battery insertion machine, comprising:

[0006] The lower frame is equipped with a conveying roller mechanism and a vibrating plate. The conveying roller mechanism can hold a battery tray, and the outlet of the vibrating plate is connected to a material distribution seat.

[0007] The nail storage module includes multiple negative pressure nail suction components, a storage bracket, a linear guide rail, and a linear slide rail. The storage bracket is mounted on the lower frame, the linear guide rail is mounted on the storage bracket, and the linear slide rail is slidably connected to the linear guide rail. Multiple negative pressure nail suction components are mounted on the linear slide rail, so that the multiple negative pressure nail suction components sequentially pick up the glue nails output from the dispensing seat.

[0008] The insertion module includes a three-axis motion assembly, an insertion connecting plate, and multiple gripper assemblies mounted on the insertion connecting plate. The three-axis motion module drives the insertion connecting plate to move the multiple gripper assemblies, which are used to grasp the adhesive pins and insert them into the corresponding battery injection holes.

[0009] Furthermore, the pin module also includes a drive assembly. Each gripper assembly includes a gripper, a gripper rotation shaft, and a transmission component. The two ends of the gripper rotation shaft are respectively connected to the gripper and the transmission component. The drive assembly is used to drive the transmission component to rotate.

[0010] Furthermore, a bearing is provided on the pin connecting plate, and the bearing is sleeved on the outer periphery of the gripper rotating shaft.

[0011] Furthermore, the drive assembly includes a rack and a drive cylinder, the drive cylinder is mounted on the pin connecting plate, the drive cylinder drives the rack, the transmission component is a rotating gear, and the teeth of the rack mesh with the teeth of each of the rotating gears.

[0012] Furthermore, the pin module also includes a guide plate and multiple detection components disposed on the guide plate. The guide plate is vertically mounted on the pin connecting plate. The detection components include a slotted photoelectric sensor, a first guide rail, and a first slide rail. The first guide rail is fixed to the guide plate, and the first slide rail is slidably connected to the first guide rail. A hook is provided on one side of the first slide rail. When the hook blocks the light between the light emitter and receiver of the slotted photoelectric sensor, the slotted photoelectric sensor outputs a sensing signal.

[0013] Furthermore, the guide plate and the first slide rail are connected in a liftable manner via a guide post, and an elastic element is sleeved on the outer periphery of the guide post, the elastic element being disposed between the guide plate and the first slide rail.

[0014] Furthermore, the detection assembly also includes a second guide rail and a second slide rail. The second guide rail is fixed to the pin connecting plate, and the second slide rail is slidably connected to the second guide rail. The second slide rail is fixedly connected to the first slide rail. A lifting cylinder is installed on the pin connecting plate, and the telescopic rod of the lifting cylinder is connected to the column plate.

[0015] Furthermore, the negative pressure nail suction assembly includes a rotary cylinder and a negative pressure nail suction component. The negative pressure nail suction component is used to pick up glue nails from the dispensing seat. The rotary cylinder is mounted on the storage bracket. The rotary cylinder drives the negative pressure nail suction component, so that the negative pressure nail suction component faces upward for the gripper assembly to grasp.

[0016] Furthermore, the three-axis motion assembly includes an X-axis guide rail, a Y-axis guide rail, and a Z-axis guide rail. The X-axis guide rail is slidably connected to the Y-axis guide rail, the Z-axis guide rail is mounted on the X-axis guide rail, and the pin connecting plate is mounted on the Z-axis guide rail.

[0017] Furthermore, the number of the plurality of negative pressure suction nail components, the plurality of gripper assemblies, and the plurality of negative pressure suction nail components are the same, and the spacing between each pair of adjacent negative pressure suction nail components, the spacing between each pair of adjacent negative pressure suction nail components, and the spacing between each pair of adjacent grippers are consistent.

[0018] Compared with existing technologies, in operation, the vibratory feeder vibrates the glue nails to the distribution seat. These nails slide on a linear guide rail, and multiple negative pressure nail-suction assemblies arranged in a straight line on the storage bracket sequentially engage with the distribution seat to pick up the glue nails. Once each negative pressure nail-suction assembly is full, the three-axis motion assembly moves, driving the nail insertion connecting plate and the gripper assembly to move as well. This aligns the gripper assemblies with each glue nail, and then drives the nail insertion connecting plate to descend. At this point, each gripper assembly can directly grab the glue nail from the corresponding negative pressure nail-suction assembly, move it directly above the battery, and then descend to insert the glue nail directly into the battery's electrolyte filling hole, completing the battery insertion. This setup allows for synchronous nail suction and insertion using multiple gripper assemblies and multiple negative pressure nail-suction assemblies in a single device, significantly improving the efficiency of inserting glue nails into the battery's electrolyte filling hole.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 8 This utility model proposes a high-speed battery insertion machine.

[0030] The high-speed battery insertion machine includes a lower frame 100, a battery storage module 200, and a battery insertion module 300. The lower frame 100 is equipped with a conveying roller mechanism 110 and a vibratory feeder 120. The conveying roller mechanism 110 can hold a battery tray 130, and the outlet of the vibratory feeder 120 is connected to a distribution seat 121. The battery storage module 200 includes multiple negative pressure battery suction components 210, a storage bracket 220, a linear guide rail 230, and a linear slide rail 240. The storage bracket 220 is mounted on the lower frame 100, the linear guide rail 230 is mounted on the storage bracket 220, and the linear slide rail 240... The 0 is slidably connected to the linear guide rail 230. Multiple negative pressure nail suction components 210 are all installed on the linear guide rail 240, so that the multiple negative pressure nail suction components 210 sequentially pick up the glue nails 122 output from the dispensing seat 121; the nail insertion module 300 includes a three-axis motion component 310, a nail insertion connecting plate 320 and multiple gripper components 330 installed on the nail insertion connecting plate 320. The three-axis motion module drives the nail insertion connecting plate 320 to move the multiple gripper components 330. The multiple gripper components 330 are used to grab the glue nails 122 and insert them into the corresponding liquid injection holes of the battery 131.

[0031] Specifically, the conveying roller mechanism 110 can receive the battery tray 130 flowing in from the external logistics line. The battery tray 130 can hold multiple rows of batteries 131. For example, if the number of multiple gripper assemblies 330 and multiple negative pressure suction nail assemblies 210 is three, then the battery tray 130 can hold three rows of batteries 131. The vibratory feeder 120 vibrates the glue nails 122 to the distribution seat 121. The glue nails 122 slide on the linear guide rail 230 via the linear slide rail 240. Multiple negative pressure suction nail assemblies 210 arranged in a straight line on the storage bracket 220 sequentially connect to the distribution seat 121 to pick up the glue nails 122. When each negative pressure suction nail assembly 210 is full of glue nails 122, the three-axis motion assembly 310 moves to drive the nail insertion connecting plate 320 and the gripper assembly 330 to move, so that multiple gripper assemblies 330 correspond one-to-one with each glue nail 122. Then, the nail insertion connecting plate 320 drives the gripper assembly 330 to descend. At this time, each gripper assembly 330 can directly grab the glue nail 122 on the corresponding negative pressure suction nail assembly 210, and then move directly to the battery 131. Then, it descends and directly inserts the glue nail 122 into the electrolyte injection hole of the battery 131 to complete the insertion of the battery 131. With this configuration, multiple gripper assemblies 330 and multiple negative pressure nail suction assemblies 210 of a single device can achieve synchronous nail suction and insertion, greatly improving the nail insertion efficiency of the battery 131 liquid injection hole.

[0032] Please see Figure 3 and Figure 7To improve the stability of the insertion of the adhesive nail 122 into the electrolyte filling hole of the battery 131, the nail insertion module 300 further includes a drive assembly 340. Each gripper assembly 330 includes a gripper 331, a gripper 331 rotating shaft, and a transmission component. The two ends of the gripper 331 rotating shaft are connected to the gripper 331 and the transmission component, respectively. The drive assembly 340 is used to drive the transmission component to rotate. Thus, the gripper 331 is rotatable, and the gripper 331 can grip the adhesive nail 122 and rotate it to insert it into the electrolyte filling hole of the battery 131, making the insertion of the adhesive nail 122 into the electrolyte filling hole of the battery 131 more tight and ensuring the quality of the insertion. The drive assembly 340 can take various forms, and the transmission component can also take various forms, as long as it is ensured that the transmission component can drive the gripper 331 rotating shaft and the gripper 331 to rotate.

[0033] Please see Figure 3 and Figure 7 Furthermore, a bearing 333 is provided on the pin connecting plate 320, and the bearing 333 is sleeved on the outer periphery of the rotating shaft of the gripper 331. Specifically, the bearing 333 can support the rotating shaft of the gripper 331, reduce friction and transmit load, and ensure the service life of the rotating function of the gripper 331.

[0034] Please see Figure 3 and Figure 7 Furthermore, the drive assembly 340 includes a rack 341 and a drive cylinder 342. The drive cylinder 342 is mounted on the pin connecting plate 320 and drives the rack 341. The transmission component is a rotating gear 334, with the teeth of the rack 341 meshing with the teeth of each rotating gear 334. Specifically, the drive cylinder 342 drives the rack 341 to move, and the rack 341 drives each rotating gear 334 to rotate. This causes the rotating gears 334 to drive the rotating shaft of the gripper 331 and the gripper 331 to rotate, making the insertion of the adhesive pin 122 into the battery 131 fluid filling hole smoother and ensuring the stability of the insertion. In this way, a single rack 341 can drive all the rotating gears 334 to rotate, achieving synchronous rotation of multiple grippers 331 during pin insertion, ensuring pin insertion quality and efficiency.

[0035] It is understandable that during the insertion process, the insertion position of the adhesive pin 122 may be misaligned or inaccurate. To facilitate checking whether the adhesive pin 122 is properly inserted into the electrolyte filling hole of the battery 131, please refer to [link to relevant documentation]. Figures 5 to 6Furthermore, the pin module 300 also includes a guide plate 350 and multiple detection components 360 disposed on the guide plate 350. The guide plate 350 is vertically mounted on the pin connecting plate 320. The detection component 360 includes a slotted photoelectric sensor 361, a first guide rail 352 and a first slide rail 363. The first guide rail 352 is fixed to the guide plate 350, and the first slide rail 363 is slidably connected to the first guide rail 352. A hook 364 is provided on one side of the first slide rail 363. When the hook 364 blocks the light between the light emitter and the receiver of the slotted photoelectric sensor 361, the slotted photoelectric sensor 361 outputs a sensing signal. Thus, during the process of the gripper 331 inserting the adhesive pin 122 into the electrolyte filling hole of the battery 131, if the bottom of the first slide rail 363 is subjected to the reaction force of the adhesive pin 122, causing the first slide rail 363 to slide on the first guide rail 352 and drive the hook 364 to move upward, when the hook 364 moves to block the light between the light emitter and receiver of the slotted photoelectric sensor 361, it is determined that the adhesive pin 122 is inserted into the electrolyte filling hole of the battery 131 in place; if the bottom of the first slide rail 363 is not subjected to the reaction force of the adhesive pin 122, and the hook 364 on the first slide rail 363 does not block the sensing part of the slotted photoelectric sensor 361, it is determined that the adhesive pin 122 is not inserted into the electrolyte filling hole of the battery 131.

[0036] Please see Figures 5 to 7 Furthermore, the guide post 365 and the first slide rail 363 are vertically connected via a guide post 365. An elastic element 362 is sleeved on the outer periphery of the guide post 365 and is located between the guide post 350 and the first slide rail 363. Specifically, the elastic element 362 can be a spring or other elastic structure to ensure that the pressure head at the bottom of the first slide rail 363 can be buffered and reset by the reaction force of the rubber nail 122. Thus, when the bottom of the first slide rail 363 is subjected to the reaction force of the rubber nail 122, the elastic element 362 compresses, and the first slide rail 363 gradually slides upward, causing the hook 364 to block the light between the light emitter and receiver of the photoelectric sensor, triggering the slotted photoelectric sensor 361. After the insertion action is completed, as the first slide rail 363 moves upward with the entire insertion assembly, it resets under the elastic force of the elastic element 362, and the hook 364 moves downward to retract the area blocking the light between the light emitter and receiver of the photoelectric sensor.

[0037] Please see Figures 5 to 7Furthermore, the detection component 360 also includes a second guide rail 366 and a second slide rail 367. The second guide rail 366 is fixed to the pin connecting plate 320, and the second slide rail 367 is slidably connected to the second guide rail 366. The second slide rail 367 is fixedly connected to the first slide rail 363. A lifting cylinder 368 is installed on the pin connecting plate 320, and the telescopic rod of the lifting cylinder 368 is connected to the through plate 350. Thus, during the process of the gripper 331 inserting the adhesive nail 122 into the electrolyte filling hole of the battery 131, the lifting cylinder 368 can drive the through plate 350 to rise and fall, causing the second slide rail 367 to slide on the second guide rail 366. Consequently, the through plate 350 can drive each first slide rail 363 to press down as a whole, so that the first slide rail 363 can be subjected to the reaction force of the adhesive nail 122. This allows the hook 364 to cover the slotted photoelectric sensor 361, thereby determining whether the adhesive nail 122 has been inserted into the electrolyte filling hole of the battery 131.

[0038] Please see Figures 1 to 4 Furthermore, the negative pressure nail suction assembly 210 includes a rotary cylinder 211 and a negative pressure nail suction component 212. The negative pressure nail suction component 212 is used to pick up the glue nails 122 from the dispensing seat 121. The rotary cylinder 211 is mounted on the storage bracket 220. The rotary cylinder 211 drives the negative pressure nail suction component 212, so that the negative pressure nail suction component 212 faces upward for the gripper assembly 330 to grasp. Specifically, the rotary cylinder 211 can drive the negative pressure nail suction component 212 to rotate. After the negative pressure nail suction component 212 picks up the glue nail 122, the rotary cylinder 211 drives the negative pressure nail suction component 212 to rotate, so that the negative pressure nail suction component 212 faces upward, making it convenient for the gripper 331 to directly descend and grasp the glue nail 122.

[0039] Please see Figures 1 to 3 Furthermore, the three-axis motion assembly 310 includes an X-axis guide rail 311, a Y-axis guide rail 312, and a Z-axis guide rail 313. The X-axis guide rail 311 is slidably connected to the Y-axis guide rail 312, the Z-axis guide rail 313 is mounted on the X-axis guide rail 311, and the pin insertion connecting plate 320 is mounted on the Z-axis guide rail 313. Thus, through the X-axis guide rail 311, the Y-axis guide rail 312, and the Z-axis guide rail 313, the gripper 331 can move in the X, Y, and Z directions to complete the pin picking and insertion actions.

[0040] Please see Figures 1 to 7Furthermore, the number of multiple negative pressure suction nail components 212, multiple gripper assemblies 330, and multiple negative pressure suction nail components 212 are the same, and the spacing between each pair of adjacent negative pressure suction nail components 212, the spacing between each pair of adjacent negative pressure suction nail components 212, and the spacing between each pair of adjacent grippers 331 are consistent. With this configuration, when the multiple negative pressure suction nail components 212 move in cooperation with the linear guide rail 230 and the linear slide rail 240, they sequentially pick up the adhesive nails 122. At the same time, when the nail insertion connecting plate 320 drives the multiple grippers 331 to descend, the multiple grippers 331 can grasp the adhesive nails 122 that have been grasped by the negative pressure suction nail components 212 at once, and the multiple grippers 331 can insert the adhesive nails 122 into the liquid injection holes of the multiple batteries 131 at once, improving the grasping efficiency.
