Description

Technical Field

[0001] This utility model relates to the field of lithium battery filling port insertion pin technology, and in particular to a pipe-type insertion pin device. Background Technology

[0002] In lithium battery production and assembly, the pin insertion process is a key step to ensure the stability of electrode connections and the charging and discharging performance of the battery. The pins must be accurately inserted into the pre-set pin positions on the battery, and the insertion depth must be consistent and without deviation. This is to avoid battery contact failures or safety hazards caused by poor pin insertion. The performance of the pin insertion equipment directly affects the quality and efficiency of lithium battery production.

[0003] Current battery insertion equipment on the market has several shortcomings: First, the feeding method mostly relies on traditional vibratory feeders or manual assistance. Vibratory feeders are prone to jamming due to the shape of the rubber nails and friction in the material channel, requiring frequent shutdowns for cleaning. Manual feeding is inefficient and prone to errors in nail placement, affecting subsequent insertion. Second, the nail positioning and drive structure is imperfect. Most equipment relies on mechanical limits for rough positioning and lacks precise calibration components. Even slight battery misalignment can lead to nail deviation and inconsistent depth. Furthermore, the insertion mechanism is mostly driven by a single axial cylinder without rotational assistance. When encountering burrs or resistance on the inner wall of the insertion hole, rubber nails are prone to jamming or incomplete insertion, increasing the failure rate. Third, the nail inspection function is disconnected from the insertion process. Some equipment lacks integrated nail inspection components, requiring transfer to a separate station for inspection, increasing process complexity and inspection errors. Even with integrated inspection structures, they are mostly contact-based hard inspections, which can easily damage batteries or rubber nails. Defective products must be manually removed, which cannot be automatically and quickly processed, extending the production cycle time. Therefore, improvements are needed. Utility Model Content

[0004] The main purpose of this utility model is to provide a pipe-type nail insertion device, which aims to solve the problems of slow feeding of nail insertion equipment, poor nail insertion accuracy, and disconnection between nail inspection and nail insertion.

[0005] To achieve the above objectives, this utility model proposes a pipe-type insertion device for use on batteries, for inserting pins into the batteries. The insertion device includes: Mounting plate; A camera positioning component is disposed on the front of the mounting plate and is used to position the pins on the battery. A pin insertion component is disposed on the front side of the mounting plate and located on the side of the camera positioning component. The pin insertion component includes a pin feeding pipe, a blow pipe assembly, a material dispensing assembly, a drive assembly, and a pin insertion assembly. The blow pipe assembly is disposed on the path of the pin feeding pipe to accelerate the falling of the rubber pins in the pin feeding pipe. The material dispensing assembly is located on the side of the pin feeding pipe to limit the falling of the rubber pins in the pin feeding pipe. The pin insertion assembly is located below the pin feeding pipe. The drive assembly is electrically connected to the camera positioning component and drives the pin insertion assembly to insert the rubber pins into the pin insertion position. A nail detection component is disposed on the front side of the mounting plate and located on the side of the nail insertion component. The nail detection component includes a nail detection assembly and a nail removal assembly. The nail detection assembly determines whether the adhesive nail is properly inserted by the amount of displacement generated by contacting the nail. The nail removal assembly removes the unqualified adhesive nail from the corresponding battery.

[0006] The beneficial effects of this utility model are as follows: By integrating the camera positioning component, the insertion component, and the inspection component on the same front of the mounting plate, the structure is compact and the layout is reasonable, which can reduce the space occupied by the equipment and improve the coordination of the movement of each component. Among them, the nail feeding pipe of the insertion component, together with the blowing pipe component, can accelerate the falling of the glue nail and avoid the material loading jamming. The material distribution component can accurately limit the falling of the glue nail to ensure the orderly material loading. The drive component is electrically connected to the camera positioning component and can drive the insertion component to accurately insert the nail according to the insertion position determined by the camera positioning component, which can effectively improve the insertion accuracy. At the same time, the inspection component of the inspection component judges whether the insertion is qualified by the displacement generated by contact with the glue nail. The nail removal component can remove the unqualified glue nail in time, without the need to set up an additional inspection station and manual removal step. The overall structural design not only solves the problems of slow loading and poor positioning of traditional insertion equipment, but also realizes the synchronous and efficient operation of insertion and inspection, which significantly improves the production efficiency and yield of the battery insertion process.

[0013] This utility model provides a pipe-type nail insertion device. Please refer to [reference needed]. Figures 1-3 This device is used on batteries to insert pins. The pin insertion device includes a mounting plate 1, a camera positioning component 2, a pin insertion component 3, and a pin detection component 4. The camera positioning component 2 is located on the front of the mounting plate 1 to position the pins on the battery. The pin insertion component 3 is located on the front of the mounting plate 1 and to the side of the camera positioning component 2. The pin insertion component 3 includes a pin feeding pipe 31, a blowing pipe assembly 32, a material distribution assembly 33, a drive assembly 34, and a pin insertion assembly 35. The blowing pipe assembly 32 is located along the path of the pin feeding pipe 31 to accelerate the falling of the pins within the pipe and prevent jamming. The material distribution assembly 33 is located to the side of the pin feeding pipe 31 to limit the falling of the pins, ensuring orderly feeding. The pin insertion assembly 35 is located below the pin feeding pipe 31. The drive assembly 34... 4 is electrically connected to the camera positioning component 2, and drives the pin insertion assembly 35 to insert the adhesive pin into the pin position. In other words, the drive assembly 34 can drive the pin insertion assembly 35 to accurately insert the pin according to the pin position determined by the camera positioning component 2, effectively improving the pin insertion accuracy. As for the pin detection component 4, it is set on the front of the mounting plate 1 and located on the side of the pin insertion component 3. The pin detection component 4 includes a pin detection component 41 and a pin removal component 42. The pin detection component 41 determines whether the adhesive pin is inserted qualified by the displacement generated by contacting the pin. The pin removal component 42 removes the unqualified adhesive pin from the corresponding battery. The above overall structural design not only solves the problems of slow feeding and poor positioning of traditional pin insertion equipment, but also realizes the synchronous and efficient operation of pin insertion and pin detection, significantly improving the production efficiency and yield of the battery pin insertion process.

[0014] In this embodiment, the blowpipe assembly 32 includes a needle tube, an air tube (not shown), and an air source (not shown). The needle tube is connected to the air source through the air tube. An air inlet 311 is provided on the side of the nail feeding pipe 31 away from the mounting plate 1. The needle tube is inclined, and the needle tip faces the air inlet 311. This design allows the airflow generated by the air source to be stably delivered to the needle tube through the air tube. Combined with the air inlet 311 pre-set on the side of the nail feeding pipe 31 away from the mounting plate 1, and the inclined needle tube with the needle tip facing the air inlet 311, the airflow is accurately guided from the air inlet 311. Inside the feeding pipe 31, the airflow can directly act on the rubber nails inside the pipe. It can accelerate the speed at which the rubber nails fall along the feeding pipe 31 through the thrust of the airflow, solving the problem of rubber nails getting stuck due to insufficient gravity or pipe friction in the traditional feeding method. It can also avoid airflow turbulence affecting the conveying path of the rubber nails by utilizing the directionality of the inclined airflow. Furthermore, in conjunction with the limiting function of the material distribution component 33, it can further ensure the continuity and orderliness of the rubber nail feeding, providing a stable feeding foundation for the subsequent nail insertion component 35 to accurately connect the nails and for the drive component 34 to accurately insert the nails based on the camera positioning component 2. In this embodiment, please refer to Figure 1 The material distribution assembly 33 includes two material distribution drive elements 331 distributed vertically. Each material distribution drive element 331 has a limiting shaft 332 at its output end. The two limiting shafts 332 are arranged horizontally, and the end of the limiting shaft 332 away from the material distribution drive element 331 is located inside the nail feeding pipe 31. Specifically, the material distribution assembly 33, through the structure of the two material distribution drive elements 331 distributed vertically and the horizontal limiting shaft 332 at their output ends, utilizes the layout design of the limiting shaft 332 extending into the nail feeding pipe 31. The extension and retraction of the limiting shaft 332 can be achieved by the alternating drive of the material distribution drive elements 331.

[0015] When the upper limiting shaft 332 extends, it can block the upper rubber nail from falling into the pipe, allowing only a single rubber nail to pass through. After the lower rubber nail is removed by the nail insertion assembly 35, the lower limiting shaft 332 extends to block subsequent rubber nails, while the upper limiting shaft 332 retracts to release the next rubber nail to the lower position. This mechanical limiting structure with upper and lower cooperation can accurately control the orderly falling of single rubber nails, avoiding multiple rubber nails from piling up and falling due to gravity or the airflow thrust of the blow pipe assembly 32. It works in coordination with the nail feeding pipe 31 and the blow pipe assembly 32 to further ensure the stability of the feeding rhythm. It also provides a reliable material supply guarantee for the nail insertion assembly 35 to accurately connect the nails and for the drive assembly 34 to accurately insert the nails. In this embodiment, please refer to Figure 1The pin assembly 35 includes a mounting base 351, a hollow rotating shaft 352, a clamping mechanism 353, and a clamping drive element 354 whose output end is connected to the clamping mechanism 353. The mounting base 351 is fixed to the front of the mounting plate 1, providing a stable mounting foundation for the entire assembly. The rotating shaft 352 passes through the mounting base 351 and is rotatably connected to it. The rotating shaft 352 is located below the pin feeding pipe 31 and its interior is connected to the pin feeding pipe 31. This achieves both the rotatability of the rotating shaft 352 and allows the glue pins in the pin feeding pipe 31 to accurately fall into the rotating shaft 352, providing a directional channel for glue pin delivery. The clamping mechanism 353 and the clamping drive element 354... All components 354 are disposed on the surface of the rotating shaft 352. The clamping mechanism 353 is driven by the clamping drive component 354 to clamp / release the glue nails that fall from the outlet end of the rotating shaft 352. It can not only stably clamp the glue nails while they are waiting to be inserted, preventing them from shifting or falling off, but also ensure that the glue nails rotate synchronously with the rotating shaft 352 when the drive component 34 drives the rotating shaft 352 to rotate. This achieves the rotating insertion action of the glue nails, effectively solving the problems of easy jamming and incomplete insertion of traditional axial nails. Together with the feeding of the nail feeding pipe 31 and the orderly feeding of the material distribution component 33, it provides key structural support for the accurate and stable insertion of glue nails into the battery nail position.

[0016] Specifically, the drive assembly 34 includes a belt drive mechanism. The driven pulley in the belt drive mechanism is connected to the end of the rotating shaft 352 near the nail feeding pipe 31 to drive the rotating shaft 352 to rotate. This design uses a belt drive mechanism, which has the characteristics of smooth transmission and shock absorption, ensuring that the rotating shaft 352 rotates at a uniform speed and reducing the impact of speed fluctuations on subsequent nail insertion. On the other hand, the power transmission path is short, which can reduce power loss and allow power to be efficiently converted into the rotational kinetic energy of the rotating shaft 352, so as to quickly realize the assembly of the glue nails. As for the specific structure of the belt drive mechanism, it includes a drive pulley, the aforementioned driven pulley, and a drive belt. In fact, the belt drive mechanism is existing technology, which should be known to those skilled in the art, and will not be described in detail here.

[0017] As for the clamping mechanism 353, in this embodiment, it is a gripper that can control the tightness, which is existing technology and will not be described in detail here.

[0018] In this embodiment, please refer to Figures 1-3The nail detection assembly 41 includes a buffer element 411, a displacement sensor 412, a detection base plate 413, and a detection guide shaft element 414. The buffer element 411 is disposed on the mounting plate 1. The displacement sensor 412, the detection base plate 413, and the detection guide shaft element 414 are disposed on the buffer element 411. When the adhesive head of the nail contacts the detection guide shaft element 414, it pushes the detection base plate 413 to move vertically. The displacement sensor 412 is disposed corresponding to the detection base plate 413 to sense its displacement and provide feedback on the nail insertion status. Specifically, the nail detection assembly 411 is constructed by placing the buffer element 411 on the mounting plate 1 and then... The structural layout of the displacement sensor 412, detection substrate 413, and detection guide shaft element 414 integrated into the buffer element 411 not only provides buffer protection for the detection component through the buffer element 411, avoiding hard contact damage to the glue nail or battery during detection, but also allows the detection guide shaft element 414 to directly translate the state of the glue nail after insertion into the vertical movement of the detection substrate 413 driven by the detection guide shaft element 414 through contact and cooperation with the glue nail head. At the same time, the displacement sensor 412 is set corresponding to the detection substrate 413, which can accurately sense the displacement of the detection substrate 413, and then convert the displacement signal into glue nail insertion status feedback. If the displacement is within the preset range, it means that the glue nail is inserted successfully; if the displacement is abnormal, it means that the insertion is unsuccessful. The above design does not require manual intervention and provides a basis for the subsequent nail removal component 42 to handle unsuccessful glue nails in a timely manner.

[0019] Following on from the above, please refer to... Figure 3 In this embodiment, the detection guide shaft element 414 includes a first reset spring 4141, a first guide shaft 4142, and a nail detection head 4143. The first guide shaft 4142 is externally sleeved with a reset spring, its bottom is fixed to the nail detection head 4143, and its top is connected to the detection substrate 413 through a bearing. When the bottom surface of the nail detection head 4143 contacts the rubber head of the nail, the first guide shaft 4142 pushes the detection substrate 413 to move upward. The displacement sensor 412 can accurately sense the displacement of the detection substrate 413. When the nail detection head 4143 no longer contacts the rubber head of the nail, the guide shaft returns to its initial position under the action of the compressed reset spring, ready for subsequent detection.

[0020] For further details, please refer to... Figure 2 and Figure 3The buffer element 411 includes a connecting plate 4111, a floating plate 4112, and a limiting sub-element 4113. The connecting plate 4111 is fixed vertically to the surface of the mounting plate 1 to provide stable mounting support for the entire buffer assembly. The floating plate 4112 is slidably disposed on the connecting plate 4111, so that when the detection guide shaft element 414 is pushed by the glue pins to move the detection substrate 413, the floating plate 4112 can slide vertically along the connecting plate 4111 synchronously with the detection substrate 413. The buffering effect is achieved through sliding displacement, avoiding damage to the glue pins or detection pin assembly from hard impacts during detection. As for component 41, the limiting sub-element 4113 is disposed on the surface of the connecting plate 4111 and located on the top of the floating plate 4112. The limiting sub-element 4113 restricts the sliding distance of the floating plate 4112 on the connecting plate 4111, thereby preventing the detection substrate 413, the detection guide shaft element 414 and other components from colliding due to excessive sliding of the floating plate 4112. At the same time, it avoids the displacement sensor 412 from making a false judgment due to sensing a displacement amount exceeding the range, further ensuring the stability and accuracy of the detection action of the nail detection assembly 41, and providing structural protection for the reliable determination of the nail insertion status.

[0021] Following the above, in this embodiment, please refer to Figure 2 and Figure 3 The limiting sub-element 4113 includes a limiting block 41131, a second return spring 41132, and a second guide shaft 41133. The limiting block 41131 is fixed to the connecting plate 4111, and the second guide shaft 41133 is movably inserted into the limiting block 41131 and is arranged in a vertical direction. The bottom of the limiting screw contacts and abuts against the top of the floating plate 4112. The second return spring 41132 is sleeved on the outside of the second guide shaft 41133. The second return spring 41132 is mainly set to assist the floating plate 4112 in returning to its initial position. Specifically, by setting the limiting block 41131 and the second guide shaft 41133, on the one hand, the moving direction of the floating plate 4112 can be stabilized and it can prevent the floating plate 4112 from rising excessively, thus avoiding damage to other structures on the mounting plate 1.

[0022] In this embodiment, the connecting plate 4111 is provided with a guide rail slider 41111, and the floating plate 4112 is provided with a groove 41121 that cooperates with the guide rail slider 41111, thereby realizing the sliding of the floating plate 4112 on the connecting plate 4111. In fact, in other embodiments, the connecting plate 4111 may also be provided with a groove 41121, and the floating plate 4112 may be provided with a guide rail slider 41111 that cooperates with the groove 41121, depending on the application environment of the overall device.

[0023] In this embodiment, please refer to Figure 2 and Figure 3The nail-removing assembly 42 is fixed to the floating plate 4112 via the connecting block 43, realizing a linkage layout with the nail detection assembly 41. When the floating plate 4112 slides with the detection action, the nail-removing assembly 42 can adjust its position synchronously to accurately align with the defective nails to be processed. The nail-removing assembly 42 is located on the side of the detection substrate 413 away from the connecting plate 4111 to avoid spatial interference with components such as the detection guide shaft element 414 and the displacement sensor 412. The nail-removing assembly 42 includes a nail-removing drive element 421 and a gripper 422 connected to the output end of the nail-removing drive element 421. The gripper 422 picks up the defective nails and moves them to the next structure. The above design not only ensures the accuracy and timeliness of the nail-removing action, but also forms a continuous process of "detection-judgment-rejection" with the nail detection assembly 41, which significantly improves the automation level and production efficiency of the nail insertion process.

[0024] In this embodiment, please refer to Figure 2 and Figure 3 The pin insertion device also includes an external robotic arm shaft assembly 5. The back of the mounting plate 1 is slidably connected to the external robotic arm shaft assembly 5. This design enables the overall structure of the mounting plate 1 to rise and fall to cooperate with the pin insertion part 3 in inserting the pin at the battery pin position, and to cooperate with the pin detection assembly 41 to sense and detect the displacement of the substrate 413. As for the buffer limiting assembly 6 provided between the top of the mounting plate 1 and the external robotic arm shaft assembly 5, the buffer limiting assembly 6 is used to buffer and limit the vertical sliding of the mounting plate 1 to prevent the mounting plate 1 from rising or falling excessively and causing damage to the battery or the pin.

[0025] Following the above, in this embodiment, the buffer limiting component 6 includes a third guide shaft 62 and a third reset spring 61. Its structural principle is the same as that of the aforementioned limiting element, the only difference being the elasticity of the spring. It is mainly to prevent the entire mounting plate 1 structure from rising or falling too much, causing damage to the corresponding structure.

[0026] In this embodiment, the camera positioning component 2 includes a camera body 21, a light source 22, and an adjustment bracket 23. The adjustment bracket 23 is fixed to the front of the mounting plate 1 and forms a compact integrated layout with the pin insertion component 3 and the pin detection component 4. The camera body 21 and the light source 22 are respectively connected to the adjustment bracket 23 through sliding connectors. The sliding connectors can slide along the length direction of the adjustment bracket 23 to adjust the position of the camera body 21 and the light source 22, thereby accurately capturing the pin insertion position on the battery and providing a unique positioning reference for subsequent pin insertion actions, ensuring pin insertion accuracy from the source.

[0027] Regarding the working principle of this nail insertion device: First, the external vibrating plate feeds the rubber nails into the nail feeding pipe 31. The blowing pipe assembly 32 accelerates the falling of the rubber nails, and the distributing assembly 33 controls the rubber nails to fall one by one into the rotating shaft 352 of the nail insertion assembly 35. The clamping mechanism 353 clamps the rubber nails. During this process, the camera positioning component 2 accurately captures the battery nail position and transmits the information to the drive assembly 34. The external robotic arm shaft assembly 5 moves the mounting plate 1 downward, causing the nail insertion assembly 35 to insert the rubber nail into the battery's insertion position. Then, the drive assembly 34 drives the rotating shaft 352 to rotate, thus rotating the rubber nail into the battery and clamping it. The tightening mechanism 353 loosens the adhesive nail; at the same time as the above working process, after the external robotic arm shaft assembly 5 drives the mounting plate 1 to move down, the bottom of the connecting plate 4111 in the nail detection assembly 41 abuts against the battery or other structures, so that the nail detection head 4143 contacts the adhesive head of another adhesive nail. Then, the displacement sensor 412 senses the displacement of the detection substrate 413 to determine whether the adhesive nail is qualified. If it is not qualified, the nail removal assembly 42 clamps it. Then the mounting plate 1 is driven to rise again by the external robotic arm shaft assembly 5, thereby removing the unqualified adhesive nail. After that, each reset spring drives the component to reset, and the nail insertion-nailing inspection is completed synchronously.

[0028] It should be noted that the process of the external robotic arm shaft assembly 5 driving the mounting plate 1 to move downwards simultaneously enables the insert pin 3 to insert the glue pin into the battery's insertion position and the bottom of the connecting plate 4111 to abut against the battery or other structures. As for the process of the external robotic arm shaft assembly 5 driving the mounting plate 1 to move upwards, it simultaneously enables the insert pin 3 to release the screwed glue pin and the gripper 422 to pick up unqualified glue pins (qualified ones are not picked up) and detach them from the battery.

[0029] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
