Description

Technical Field

[0001] This invention relates to the field of battery module welding technology, specifically to a material feeding and positioning mechanism for solid-state battery module welding. Background Technology

[0002] The positioning fixture for solid-state battery module welding is a clamp specifically designed for precise positioning of solid-state battery cells and connectors, ensuring that the position does not shift and the gap is uniform during welding, thereby improving welding accuracy and module consistency.

[0003] However, traditional positioning fixtures for solid-state battery module welding are prone to displacement during the feeding and conveying process, and require machine stoppage when reaching the welding station, affecting continuous production efficiency. At the same time, the clamping structure on the fixture is fixed, making it difficult to adapt to battery modules of different specifications and sizes, resulting in poor versatility. Furthermore, although some conveyor lines are equipped with lifting mechanisms to achieve welding without stopping the machine, the lifting height limit structure is of a fixed length and cannot be adjusted. When dealing with different lifting heights required for different specifications of modules, problems such as over-lifting or under-lifting are likely to occur. Summary of the Invention

[0004] The purpose of this invention is to provide a material feeding and positioning mechanism for solid-state battery module welding, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a material feeding and positioning mechanism for welding solid-state battery modules, comprising a frame, a pair of roller chain conveying modules symmetrically arranged on both sides of the frame, a baffle on one side of each of the two roller chain conveying modules, a tooling placed on the roller chain conveying module between the two baffles, a clamping component on the tooling, a blocking component inside the frame, and a lifting component on one side of the blocking component;

[0006] The clamping assembly includes a transverse plate disposed on a tooling, a pair of transverse clamps symmetrically disposed on both sides of the transverse plate, a pair of radial plates disposed on the tooling on both the front and rear sides of the transverse plate, and radial clamps disposed on several of the radial plates.

[0007] Using the above technical solution, the frame serves as the installation base for the entire device. The roller chain conveying modules on both sides of the frame are used to advance the tooling containing the battery module body to be welded without stopping the machine. The baffles on both sides of the frame can laterally limit the tooling during the conveying process to prevent deviation. The tooling provides an installation base for the clamping components and can stably clamp the battery module body. The roller chain conveying modules can operate without stopping the machine. The rollers rotate and form rolling friction with the bottom of the tooling, avoiding damage to the bottom of the tooling.

[0008] Preferably, two rows of mounting holes are provided on both the transverse plate and the radial plate, bolts are provided between the transverse clamp and the radial clamp and the transverse plate and the radial plate, and the battery module body is placed between the transverse clamp and the radial clamp.

[0009] Using the above technical solution, the transverse plate on the tooling provides the mounting base for the transverse clamp and the radial plate provides the mounting base for the radial clamp. The transverse clamp clamps the battery module body from the transverse direction and the radial clamp clamps from the radial direction. In addition, there are two rows of mounting holes on both the transverse plate and the radial plate. The mounting holes, together with bolts, can adjust the position of the transverse clamp and the radial clamp to adapt to battery module bodies of different specifications.

[0010] Preferably, the blocking assembly includes a laser rangefinder sensor mounted on a frame on one side of the roller chain conveyor module, and a mounting frame is provided at the bottom of the frame, with a telescopic cylinder at the bottom of the mounting frame.

[0011] Using the above technical solution, the laser rangefinder in the blocking component is used to detect the position of the tooling and output a signal to the controller. The controller determines whether it has reached the preset position. The mounting frame provides the mounting base for the telescopic cylinder and the connector.

[0012] Preferably, a connector is provided on a mounting bracket on one side of the telescopic cylinder, and a buffer block is movably provided on the connector. The top of the telescopic rod of the telescopic cylinder is connected to one end of the buffer block, and a pressure groove corresponding to the buffer block is provided at the front of the tooling.

[0013] Using the above technical solution, connector one provides an installation base for the buffer blocking block and allows the buffer blocking block to rotate a certain angle around connector one. When the tooling reaches the preset position, the telescopic rod of telescopic cylinder one extends, driving the buffer blocking block to rotate a certain angle around connector one. The buffer blocking block is then engaged in the pressure groove at the front of the tooling, achieving precise blocking and positioning of the tooling. At the same time, the buffer blocking block avoids rigid impact damage to the tooling through buffer contact.

[0014] Preferably, the lifting assembly includes a pair of mounting brackets 2 disposed at the bottom of the frame, each mounting bracket 2 having a telescopic cylinder 2 at its bottom, each telescopic cylinder 2 having a displacement sensor embedded in its telescopic rod, each telescopic cylinder 2 having a lifting plate at its top, each lifting plate having a pair of guide posts at its bottom, and each mounting bracket 2 having a guide sleeve at the position corresponding to the guide posts.

[0015] Using the above technical solution, the mounting frame 2 in the lifting assembly provides the mounting base for the telescopic cylinder 2. The telescopic cylinder 2 drives the lifting plate to rise and fall through the telescopic rod. The displacement sensor embedded in the telescopic rod of the telescopic cylinder 2 can detect the lifting height in real time and feed it back to the controller. When the preset value is reached, the subsequent welding process is triggered. The lifting plate is used to lift the tooling, so that the tooling is lifted and separated from the roller chain conveyor module. The guide column at the bottom of the lifting plate cooperates with the guide sleeve on the mounting frame 2 to ensure the stability of the lifting plate during lifting.

[0016] Preferably, each of the two lifting plates is provided with a positioning pin at its top, and the bottom of the tooling is provided with a positioning groove corresponding to the position of the positioning pin.

[0017] Using the above technical solution, the positioning pins on the lifting plate are used to insert into the positioning slots at the bottom of the tooling to achieve further positioning of the tooling.

[0018] Preferably, each of the lifting plates is symmetrically provided with a pair of L-shaped limiting plates on both sides, and the bottom of both L-shaped limiting plates passes through the second mounting frame. Each of the second mounting frames is provided with a fixed limiting cylinder on both sides of its bottom. A lead screw is provided inside the fixed limiting cylinder through a support seat. A telescopic limiting rod is spirally sleeved on the outside of the lead screw. A guide rail is provided on the inner wall of the fixed limiting cylinder. The telescopic limiting rod is slidably mounted on the guide rail. A scale is provided on the outer wall of the telescopic limiting rod. A contact switch is provided at the bottom of the telescopic limiting rod.

[0019] Using the above technical solution, the L-shaped limiting plates on both sides of the lifting plate rise synchronously with the lifting plate. When they contact the telescopic limiting rod, they trigger a contact switch to limit the maximum lifting height and avoid over-lifting. The support seat in the fixed limiting cylinder provides support for the lead screw, ensuring the stability of the lead screw during rotation. When the lead screw rotates, it converts its own rotational motion into the linear motion of the telescopic limiting rod, causing the telescopic limiting rod to rise and fall along the guide rail on the inner wall of the fixed limiting cylinder. The telescopic limiting rod is used to cooperate with the L-shaped limiting plate to limit the maximum lifting height of the lifting plate, adapting to different specifications of battery modules. The scale on the outer wall of the telescopic limiting rod can intuitively display the height, facilitating quick and accurate adjustment.

[0020] Preferably, the bottom of the mounting bracket two on one side of the fixed limiting cylinder is provided with a square groove, and a rotating shaft is provided in the square groove through a bearing seat. A sprocket one is sleeved on the outside of the rotating shaft, and a sprocket two is sleeved on the outside of the lead screw. A chain is provided between the sprocket one and the sprocket two.

[0021] Using the above technical solution, the square groove at the bottom of the mounting bracket 2 provides a mounting base for the rotating shaft. When the rotating shaft rotates, it drives the sprocket 1 to rotate synchronously. The sprocket 1 transmits power to the sprocket 2 through the chain, and the sprocket 2 drives the lead screw to rotate.

[0022] Preferably, one end of the rotating shaft is provided with an operating handle, one side of the operating handle is provided with a mounting bracket three, a locking rod is provided through the mounting bracket three, one end of the locking rod is provided through the operating handle, a disc is provided on the outside of the locking rod, and a spring is provided between the disc and the mounting bracket three.

[0023] Using the above technical solution, the operating handle is manually rotated to adjust the height of the telescopic limit rod. Mounting bracket three provides a mounting base for the locking rod, which can be inserted into or removed from the locking hole of the limit plate to lock and unlock the rotating shaft, preventing the rotating shaft from rotating accidentally after adjustment. The disc provides a mounting base for the spring, which provides a restoring force for the locking rod, ensuring that it is stably inserted into the locking hole to fix the rotating shaft, or to stably engage the male and female buckles, avoiding affecting the rotation of the operating handle.

[0024] Preferably, a pair of male buckles are provided on the outer side of the locking rod on the side of the disc away from the spring, a female buckle is provided on the inner wall of the mounting bracket three, a cover plate is provided at the bottom of the mounting bracket two corresponding to the square groove, a limiting plate is provided at the bottom of the cover plate on the outer side of the rotating shaft, and several locking holes corresponding to the locking rod are opened at the bottom of the limiting plate, and a rubber layer is provided on the inner wall of each locking hole.

[0025] Using the above technical solution, the cover plate can protect the internal components of the square groove from external environmental interference, and the rubber layer on the inner wall of the locking hole on the limit plate can increase friction, improve the stability of the locking rod when locking, and prevent loosening.

[0026] Compared with the prior art, the beneficial effects of the present invention are: the solid-state battery module welding loading and positioning mechanism:

[0027] 1. The roller chain conveyor module operates continuously to transport the tooling containing the battery module body to be welded. The rollers rotate and create rolling friction with the bottom of the tooling, which can avoid damage to the bottom of the tooling and extend its service life. Secondly, the baffles on both sides of the frame can laterally limit the tooling, effectively preventing the tooling from shifting and ensuring the stability during transport. In addition, the tooling provides the mounting base for the clamping components and is used to hold the battery module body to be welded. The horizontal plate and radial plate provide the mounting base for the horizontal clamp and radial clamp, respectively. The horizontal clamp and radial clamp clamp the battery module body from different directions to center and fix it. At the same time, there are two rows of mounting holes on both the horizontal plate and the radial plate. With the help of bolts, the position of the horizontal clamp and radial clamp can be adjusted to adapt to battery module bodies of different specifications.

[0028] 2. The laser rangefinder in the blocking assembly can accurately detect the position of the tooling and output a signal to the controller to determine whether it has reached the preset position and achieve precise positioning. Secondly, when the tooling reaches the preset position, the telescopic rod of the telescopic cylinder one extends, driving the buffer blocking block to rotate around the connector one as the center and lock into the pressure groove at the front of the tooling to achieve precise blocking and positioning of the tooling. At the same time, the buffer contact can avoid rigid impact damage to the tooling.

[0029] 3. The telescopic cylinder two in the lifting assembly drives the lifting plate to rise and fall via the telescopic rod. The displacement sensor embedded in the telescopic rod can detect the lifting height in real time and provide feedback to the controller. When the preset value is reached, the subsequent welding process is triggered. Secondly, the positioning pin on the lifting plate inserts into the positioning groove at the bottom of the fixture, enabling further positioning of the fixture. The lifting plate can lift the fixture, causing it to detach from the roller chain conveyor module. The stability of the lifting plate during lifting is ensured by the cooperation between the guide post at the bottom of the lifting plate and the guide sleeve on the mounting frame two. Furthermore, the L-shaped limit plates on both sides of the lifting plate, in conjunction with the telescopic limit rods and contact switches on both sides of the bottom of the mounting frame two, limit the maximum lifting height, preventing over-lifting. When the height of the telescopic limit rods needs to be adjusted... During operation, the operator can first pull down the locking rod to remove it from the locking hole on the limit plate. When pulling it out, the disc compresses the spring. After rotating 90 degrees, the male buckle is engaged with the female buckle. The spring provides a restoring force to fix the position of the locking rod so as not to obstruct the rotation of the operating handle. The operator can then rotate the operating handle to drive the lead screw to rotate, converting the rotational motion of the lead screw into the linear motion of the telescopic limit rod. This causes the telescopic limit rod to rise and fall along the guide rail on the inner wall of the fixed limit cylinder. The scale on the outer wall of the telescopic limit rod helps the operator to accurately control and adjust the height. After adjustment, the operator can then insert the locking rod into the corresponding locking hole on the limit plate to fix the operating handle and the rotating shaft. The rubber layer on the inner wall of the locking hole on the limit plate further enhances the stability during locking. Attached Figure Description

The mounting holes 55, together with the bolts, can adjust the position of the transverse clamp 52 and the radial clamp 54 to adapt to battery module bodies 56 of different specifications.

[0050] The blocking component 6 includes a laser range sensor 61 mounted on a frame 1 on one side of the roller chain conveyor module 2, a mounting bracket 62 at the bottom of the frame 1, and a telescopic cylinder 63 at the bottom of the mounting bracket 62.

[0051] A connector 64 is provided on the mounting bracket 62 on one side of the telescopic cylinder 63. A buffer block 65 is movably provided on the connector 64. The top of the telescopic rod of the telescopic cylinder 63 is connected to one end of the buffer block 65. A pressure groove 66 corresponding to the buffer block 65 is provided at the front of the tooling 4.

[0052] Referring to the attached diagrams in the instruction manual Figures 1-14 As shown, firstly, the laser rangefinder 61 in the blocking assembly 6 is used to detect the position of the tooling 4 and output a signal to the controller. The controller determines whether it has reached the preset position. The mounting bracket 62 provides the mounting base for the telescopic cylinder 63 and the connector 64. Secondly, the connector 64 provides the mounting base for the buffer blocking block 65 and allows the buffer blocking block 65 to rotate a certain angle around the connector 64. When the tooling 4 reaches the preset position, the telescopic rod of the telescopic cylinder 63 extends, driving the buffer blocking block 65 to rotate a certain angle around the connector 64. The buffer blocking block 65 is engaged in the pressure groove 66 at the front of the tooling 4, realizing the precise blocking and positioning of the tooling 4. At the same time, the buffer blocking block 65 avoids rigid impact damage to the tooling 4 through buffer contact.

[0053] The lifting assembly 7 includes a pair of mounting brackets 71 at the bottom of the frame 1. Each mounting bracket 71 has a telescopic cylinder 72 at its bottom. Each telescopic cylinder 72 has a displacement sensor embedded in its telescopic rod. Each telescopic cylinder 72 has a lifting plate 73 at its top. Each lifting plate 73 has a pair of guide posts 74 at its bottom. Each mounting bracket 71 has a guide sleeve 75 at the position corresponding to the guide posts 74.

[0054] The top of each of the two lifting plates 73 is provided with a positioning pin 76, and the bottom of the tooling 4 is provided with a positioning groove 77 corresponding to the position of the positioning pin 76.

[0055] Referring to the attached diagrams in the instruction manual Figures 1-14 As shown, firstly, the mounting bracket 71 in the lifting assembly 7 provides a mounting base for the telescopic cylinder 72. The telescopic cylinder 72 drives the lifting plate 73 to rise and fall through the telescopic rod. The displacement sensor embedded in the telescopic rod of the telescopic cylinder 72 can detect the lifting height in real time and feed it back to the controller. When the preset value is reached, the subsequent welding process is triggered. The lifting plate 73 is used to lift the fixture 4, so that the fixture 4 is lifted and separated from the roller chain conveying module 2. The guide post 74 at the bottom of the lifting plate 73 cooperates with the guide sleeve 75 on the mounting bracket 71 to ensure the stability of the lifting plate 73 when it rises and falls. Secondly, the positioning pin 76 on the lifting plate 73 is used to insert into the positioning groove 77 at the bottom of the fixture 4 to achieve further positioning of the fixture 4.

[0056] Each lifting plate 73 has a pair of L-shaped limiting plates 728 symmetrically arranged on both sides. The bottom of both L-shaped limiting plates 728 passes through the mounting frame 71. Each mounting frame 71 has a fixed limiting cylinder 78 on both sides of its bottom. A lead screw 79 is installed inside the fixed limiting cylinder 78 through a support seat. A telescopic limiting rod 710 is spirally sleeved on the outside of the lead screw 79. A guide rail 711 is provided on the inner wall of the fixed limiting cylinder 78. The telescopic limiting rod 710 is slidably mounted on the guide rail 711. A scale 712 is provided on the outer wall of the telescopic limiting rod 710. A contact switch is provided at the bottom of the telescopic limiting rod 710.

[0057] A square groove 713 is provided at the bottom of the mounting bracket 2 71 on one side of the fixed limiting cylinder 78. A rotating shaft 714 is provided in the square groove 713 through a bearing seat. A sprocket 1 715 is sleeved on the outside of the rotating shaft 714. A sprocket 2 716 is sleeved on the outside of the lead screw 79. A chain 717 is provided between the sprocket 1 715 and the sprocket 2 716.

[0058] An operating handle 718 is provided at one end of the rotating shaft 714. A mounting bracket 719 is provided on one side of the operating handle 718. A locking rod 720 is provided through the mounting bracket 719. One end of the locking rod 720 passes through the operating handle 718. A disc 721 is provided on the outside of the locking rod 721. A spring 722 is provided between the disc 721 and the mounting bracket 719.

[0059] A pair of male buckles 723 are provided on the outer side of the locking rod 720 on the side of the disc 721 away from the spring 722. A female buckle 724 is provided on the inner wall of the mounting bracket three 719. A cover plate 727 is provided at the bottom of the mounting bracket two 71, corresponding to the position of the square groove 713. A limit plate 725 is provided at the bottom of the cover plate 727 on the outer side of the rotating shaft 714. Several locking holes 726 corresponding to the locking rod 720 are opened at the bottom of the limit plate 725. A rubber layer is provided on the inner wall of each locking hole 726.

[0060] Referring to the attached diagrams in the instruction manual Figures 1-14As shown, firstly, the L-shaped limiting plates 728 on both sides of the lifting plate 73 rise synchronously with the lifting plate 73. When they contact the telescopic limiting rod 710, they trigger a contact switch to limit the maximum lifting height and prevent over-lifting. The support seat in the fixed limiting cylinder 78 provides support for the lead screw 79, ensuring the stability of the lead screw 79 during rotation. When the lead screw 79 rotates, it converts its rotational motion into the linear motion of the telescopic limiting rod 710, causing the telescopic limiting rod 710 to rise and fall along the guide rail 711 on the inner wall of the fixed limiting cylinder 78. The telescopic limiting rod 710 is used to cooperate with the L-shaped limiting plates 728 to limit the maximum rising height of the lifting plate 73, adapting to different specifications of battery modules. The scale 712 on the outer wall of the telescopic limiting rod 710 can intuitively display the height, facilitating quick and accurate adjustment. Secondly, the square groove 713 at the bottom of the mounting bracket 71 provides an installation base for the rotating shaft 714. When the rotating shaft 714 rotates, it drives the sprocket 715 to rotate synchronously. The sprocket 715 passes through... Power is transmitted to sprocket 716 via chain 717, which drives screw 79 to rotate. Additionally, operating handle 718 allows manual rotation to adjust the height of telescopic limit rod 710. Mounting bracket 719 provides a mounting base for locking rod 720, which can be inserted into or removed from locking hole 726 of limit plate 725 to lock and unlock shaft 714, preventing accidental rotation of shaft 714 after adjustment. Disc 721 provides a mounting base for spring 722, which provides restoring force to locking rod 720, ensuring stable insertion into locking hole 726 to fix shaft 714, or to stably engage male and female buckles 723 and 724, preventing interference with operating handle 718 rotation. Finally, cover plate 727 protects internal components of square groove 713 from external environmental interference. Rubber layer on the inner wall of locking hole 726 on limit plate 725 increases friction, improving the stability of locking rod 720 during locking and preventing loosening.

[0061] Working principle: When using the solid-state battery module welding loading and positioning mechanism, first, according to the specifications and dimensions of the battery module body 56, adjust the positions of the horizontal clamp 52 and radial clamp 54 through the two rows of mounting holes 55 on the horizontal plate 51 and radial plate 53 of the tooling 4, and use bolts to ensure that the horizontal clamp 52 and radial clamp 54 stably center and clamp the battery module body 56. The roller chain conveyor module 2 conveys the tooling 4 carrying the battery module body 56, and the baffles 3 on both sides limit the movement of the tooling 4. To prevent deviation during transport, when the laser rangefinder 61 on the frame 1 detects that the fixture 4 has reached the preset position, the controller controls the telescopic rod of the telescopic cylinder 63 to extend and push the buffer block 65 to rotate at a certain angle around the connector 64, so that the buffer block 65 is engaged in the pressure groove 66 at the front of the fixture 4, thereby achieving precise blocking and positioning of the fixture 4. The roller chain conveying module 2 does not stop, and the rotation of the rollers causes rolling friction between the roller chain conveying module 2 and the fixture 4, which can avoid damage to the fixture 4.

[0062] Meanwhile, the telescopic rods of the two telescopic cylinders 72 on both sides of the lifting assembly 7 extend, driving the lifting plate 73 to rise. The guide post 74 at the bottom of the lifting plate 73 cooperates with the guide sleeve 75 on the mounting bracket 71 to ensure the stability of the lifting plate 73 when it rises. The positioning pin 76 on the lifting plate 73 is precisely inserted into the positioning groove 77 at the bottom of the tooling 4 to complete the secondary positioning of the tooling 4. When the lifting plate 73 rises, it will also drive the L-shaped limit plates 728 on both sides to rise synchronously. When the L-shaped limit plate 728 contacts the bottom of the telescopic limit rod 710 and triggers the contact switch, the controller controls the telescopic rod of the two telescopic cylinders 72 to stop extending further to avoid over-lifting. The displacement sensor embedded in the telescopic rod of the two telescopic cylinders 72 monitors the lifting height in real time. When the height preset by the controller is reached, the subsequent welding process can be triggered.

[0063] When it is necessary to adjust the extension length of the telescopic limit rod 710 to adapt to battery module bodies 56 of different specifications and sizes, the locking rod 720 can be pulled down first, so that the locking rod 720 exits the locking hole 726 on the limit plate 725. The disc 721 compresses the spring 722, and after rotating 90 degrees, the male buckle 723 on the locking rod 720 is engaged with the female buckle 724 on the inner wall of the mounting bracket three 719. The spring 722 provides a restoring force for the disc 721 and the locking rod 720 to ensure that the male buckle 723 and the female buckle 724 are stably engaged, thereby temporarily fixing the locking rod 720 to avoid obstructing the rotation of the operating handle 718. The operator rotates the operating handle 718, which drives the rotating shaft 714 to rotate synchronously. The rotating shaft 714 drives the first sprocket 715 to rotate synchronously. The first sprocket 715 transmits power to the second sprocket 716 through the chain 717. This drives the lead screw 79 inside the fixed limiting cylinder 78 to rotate, converting the rotational motion of the lead screw 79 into the linear motion of the telescopic limiting rod 710. This causes the telescopic limiting rod 710 to rise and fall along the guide rail 711 on the inner wall of the fixed limiting cylinder 78. The scale 712 on the outer wall of the telescopic limiting rod 710 helps the operator quickly adjust its height. After adjustment, pull the locking rod 720 down again, causing the male buckle 723 to disengage from the female buckle 724. After reversing 90 degrees, align the locking rod 720 with the locking hole 726 on the limiting plate 725 and insert it. Under the restoring force of the spring 722, the locking rod 720 is firmly inserted into the locking hole 726. At the same time, the rubber layer on the inner wall of the locking hole 726 further enhances the locking stability, thus fixing the telescopic limiting rod 710. After adjusting the preset lifting height of the controller's lifting plate 73, the entire device can be operated.
