Description

Technical Field

[0001] This invention relates to the field of battery component assembly technology, and in particular to a fully automated assembly equipment and method for battery cover plate components. Background Technology

[0002] The power battery system (power battery PACK, battery pack) is the core energy source that provides driving power for new energy vehicles and is one of the most critical components of new energy vehicles. The power battery system mainly consists of battery modules, electrical systems, thermal management systems, housings, and BMS, etc. The housing encapsulates the battery modules, electrical systems, thermal management systems, and BMS, forming the main body of the power battery system.

[0003] The battery system casing (battery case) serves as the carrier of the battery module, playing a crucial role in the stable operation and safety protection of the battery module. The battery cover is a core component of the battery case, and as shown in the figure, it generally includes the positive electrode assembly, negative electrode assembly, bracket, cover plate, and two clamping blocks. During assembly, the positive and negative electrode assemblies and bracket are assembled together, then the cover plate is assembled with the bracket. Finally, the two clamping blocks are respectively assembled onto the positive and negative electrode assemblies and riveted to secure the components.

[0004] Current technologies employ assembly lines where components are manually assembled according to a set process. However, due to the small size of the battery cover components, manual assembly is labor-intensive, time-consuming, and costly, and prone to errors. Therefore, large-scale, high-quality assembly of battery cover assemblies is currently difficult to achieve. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by designing a fully automated assembly equipment and method for battery cover components, which solves the problems of high cost and low efficiency in manual assembly of battery cover components.

[0006] The technical solution of the present invention to achieve the above objectives is a fully automatic assembly equipment for battery cover plate assemblies, comprising: A turntable, which is rotatable, is provided with a plurality of positioning fixtures distributed along the circumference, which are used to position the various components in the battery cover assembly. and arranged sequentially around the turntable: The first feeding mechanism and the second feeding mechanism are respectively used to place the positive electrode component and the negative electrode component onto the corresponding positioning fixtures on the turntable; The first leveling unit is used to flatten the positive electrode assembly and the negative electrode assembly placed on the positioning fixture. Support feeding unit, used to supply supports; A bracket gripping mechanism is used to grip the bracket and assemble it with the positive and negative components on the positioning fixture; Cover plate feeding unit, used to supply cover plates; A cover plate gripping mechanism is used to grip the cover plate and assemble it together with the bracket, positive electrode assembly and negative electrode assembly on the positioning fixture; The second leveling unit is used to flatten the cover plate placed on the positioning fixture. The first pressing block feeding unit and the second pressing block feeding unit are respectively used to place the positive electrode pressing block and the negative electrode pressing block onto the positive electrode assembly and the negative electrode assembly on the positioning fixture; A feeding and gripping mechanism is used to remove the assembled battery cover assembly from the positioning fixture.

[0007] Furthermore, a fixed plate is provided above the turntable. The fixed plate is non-rotatable and coaxial with the turntable. The bracket gripping mechanism and the cover plate gripping mechanism are fixedly installed on the fixed plate.

[0008] Furthermore, the bottom of the turntable is provided with a rotary device and a drive mechanism for driving the rotary device. The rotary device has a rotatable drive shaft and a non-rotatable fixed shaft. The drive shaft is a hollow shaft. The fixed shaft is located inside the drive shaft and the drive shaft is coaxial. The bottom of the turntable is connected to the drive shaft. The fixed shaft passes through the turntable and is connected to the bottom of the fixed turntable.

[0009] Furthermore, the first leveling unit includes two first positioning plates that can move towards or away from each other, two second positioning plates that can move towards or away from each other, and a pressure block that can be raised and lowered. The two first positioning plates and the two second positioning plates each have a positioning groove on their opposite sides. The positioning groove is used to position the rivets on the positive electrode assembly and the negative electrode assembly. The first positioning plates and the second positioning plates can move downward as the pressure block is pressed down and gradually contact the upper surface of the positioning fixture.

[0010] Furthermore, the support feeding unit includes a vibratory plate, a direct vibration component connected to the discharge port of the vibratory plate, and a feeding mechanism connected to the discharge port of the direct vibration component. The feeding mechanism includes a sliding plate that can move closer to or further away from the support gripping mechanism, and the sliding plate has a first positioning groove for positioning the support.

[0011] Furthermore, the bracket gripping mechanism includes a first forward and backward moving cylinder fixedly arranged horizontally, a cylinder fixing plate connected to the output end of the first forward and backward moving cylinder, a first lifting cylinder fixedly installed vertically on the cylinder fixing plate, a mounting block connected to the output end of the first lifting cylinder, and at least one suction cup disposed on the mounting block.

[0012] Furthermore, the cover plate feeding unit includes a carrier plate, a hopper for storing stacked battery cover plates, and a pushing mechanism for pushing the battery cover plates at the bottom of the hopper one by one to the outside of the hopper. The cover plate gripping mechanism is located on the opposite side of the cover plate feeding unit. The cover plate gripping mechanism includes a second forward and backward moving cylinder fixedly arranged horizontally, a cylinder fixing plate connected to the output end of the second forward and backward moving cylinder, a second lifting cylinder fixedly installed vertically on the cylinder fixing plate, a T-shaped plate connected to the output end of the second lifting cylinder, and two finger cylinders respectively installed on both sides of the T-shaped plate. The finger cylinders are equipped with grippers.

[0013] Furthermore, two third positioning plates and two fourth positioning plates capable of moving towards or away from each other are respectively provided below the carrier plate and below the cover plate gripping mechanism. Positioning grooves are provided on opposite sides of the two third positioning plates and the two fourth positioning plates. The positioning grooves are used to position the rivets on the positive electrode assembly and the negative electrode assembly. The third positioning plates and the fourth positioning plates are configured to move away from the positive electrode assembly and the negative electrode assembly respectively when the cover plate gripping mechanism gradually moves the gripped cover plate closer to the positive electrode assembly and the negative electrode assembly.

[0014] Furthermore, the first pressing block feeding unit and the second pressing block feeding unit have the same structure. The first pressing block feeding unit includes a vibratory plate, a direct vibration component connected to the discharge port of the vibratory plate, a misalignment adjustment mechanism connected to the discharge port of the direct vibration component, and a pressing block gripping mechanism for gripping the pressing block from the misalignment adjustment mechanism and placing it on the positive or negative electrode component located on the positioning fixture. The misalignment adjustment mechanism is used to rotate and adjust the position of the pressing block.

[0015] This invention also proposes a battery cover assembly assembly method, applied to the fully automated battery cover assembly equipment described above. The assembly method includes the following steps: S1. The positive electrode component and the negative electrode component are placed on the positioning fixture for positioning by the first feeding mechanism and the second feeding mechanism respectively, and then the positive electrode component and the negative electrode component are flattened. S2. The bracket is picked up from the bracket feeding unit by the bracket gripping mechanism and placed on the positioning fixture in place, so that the bracket is assembled with the positive electrode component and the negative electrode component. S3. The cover plate is picked up from the cover plate feeding unit by the cover plate gripping mechanism and placed on the positioning fixture in place. Then the cover plate is flattened so that the cover plate is assembled with the bracket, positive electrode assembly and negative electrode assembly. S4. The positive electrode block and the negative electrode block are fed through the first pressing block feeding unit and the second pressing block feeding unit respectively, and the positive electrode block and the negative electrode block are placed on the positive electrode component and the negative electrode component located on the positioning fixture after being transferred to the position, thereby completing the assembly of the positive electrode block and the positive electrode component and the assembly of the negative electrode block and the negative electrode component, so as to obtain the assembled battery cover plate assembly. S4. The battery cover assembly, which has been transferred to the positioning fixture, is removed from the positioning fixture by the feeding and gripping mechanism.

[0016] Its advantages over existing technologies are: The battery cover assembly equipment provided in this invention has the advantages of high automation and high assembly accuracy. The equipment integrates functions such as automatic loading and unloading, automatic feeding, automatic gripping and assembly, which can meet the needs of large-scale assembly of battery cover assemblies and save labor costs.

[0017] The positioning fixture positions the various components of the battery cover assembly. During assembly, the positive and negative electrode components are first placed onto the positioning fixture by the first and second feeding mechanisms for positioning. Then, the positive and negative electrode components are flattened to ensure assembly accuracy. Next, the bracket gripping mechanism picks up the bracket from the bracket feeding unit and places it onto the positioning fixture in its proper position, assembling the bracket with the positive and negative electrode components. Then, the cover plate gripping mechanism picks up the cover plate from the cover plate feeding unit and places it onto the positioning fixture in its proper position, flattening the cover plate to align with the bracket, positive electrode component, and negative electrode assembly. The components are assembled together, and then flattened by the second leveling unit. Then, the positive and negative electrode blocks are fed by the first and second pressing block feeding units respectively, and placed on the positive and negative electrode components located on the positioning fixtures. This completes the assembly of the positive electrode block with the positive electrode component and the negative electrode block with the negative electrode component, thus obtaining the assembled battery cover assembly. Finally, the battery cover assembly located on the positioning fixture is removed from the positioning fixture by the unloading gripping mechanism. The empty positioning fixture will continue to circulate, thus realizing the connection between each process.

[0018] The equipment uses a circular turntable to realize the cyclical operation of the fixture, connecting each process. The overall spatial layout is compact, and the workstations are cleverly coordinated. The first and second leveling units are used to flatten the corresponding parts before connecting each process. This serves two purposes: first, to press the parts tightly together so that they can be assembled together; and second, to ensure that each part can be accurately positioned on the positioning fixture, which greatly improves the assembly accuracy and provides a guarantee for the final riveting.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] A preferred embodiment of the present invention provides a fully automated assembly equipment for battery cover components, which can automatically load and unload materials and automatically assemble them.

[0023] For details, see Figure 1 The equipment mainly includes a machine base 1, a turntable 2, a first feeding mechanism 4, a second feeding mechanism 5, a first leveling unit 6, a support feeding unit 7, a support gripping mechanism 8, a cover plate feeding unit 10, a cover plate gripping mechanism 11, a second leveling unit 12, a first pressing block feeding unit 13, a second pressing block feeding unit 14, a discharging gripping mechanism 15, and a discharging conveyor line 16. The turntable 2 is mounted on the machine base 1. The first feeding mechanism 4, the second feeding mechanism 5, the first leveling unit 6, the support feeding unit 7, the support gripping mechanism 8, the cover plate feeding unit 10, the cover plate gripping mechanism 11, the second leveling unit 12, the first pressing block feeding unit 13, the second pressing block feeding unit 14, the discharging gripping mechanism 15, and the discharging conveyor line 16 are distributed in a counter-clockwise direction along the circumference of the turntable 2.

[0024] The bracket gripping mechanism 8 and the cover plate gripping mechanism 11 are both installed in the circumferential direction of the fixed disk 9, and the bracket gripping mechanism 8 and the cover plate gripping mechanism 11 are respectively arranged opposite to the bracket feeding unit 7 and the cover plate feeding unit 10.

[0025] like Figures 2-3 As shown, the turntable 2 serves as a rotating conveyor component, and multiple positioning fixtures 3 are mounted on the turntable 2. These positioning fixtures 3 are evenly distributed along the circumference of the turntable 2. The positioning fixtures 3 are used to position the various components of the battery cover assembly, which includes a positive electrode assembly 25, a negative electrode assembly 26, a bracket 27, a cover 28, a positive electrode pressing block 29, and a negative electrode pressing block 30 (see...). Figure 24 ).

[0026] A rotary device 18 and a drive mechanism 19 are provided at the bottom of the turntable 2, and both the rotary device 18 and the drive mechanism 19 are mounted on the machine base 1.

[0027] See Figure 4 The rotary device 18 employs a cam divider. The cam divider has a worm gear 183, a drive shaft 181, and a fixed shaft 182. The cam (not shown) on the worm gear 183 meshes with the worm wheel (not shown) on the drive shaft 181. Rotation of the worm gear 183 drives the drive shaft 181 to rotate. Both ends of the worm gear 183 extend from the cam divider. The drive mechanism 19 uses a motor, which drives the worm gear 183 to rotate via a belt.

[0028] Specifically, pulleys are installed at both the output end of the motor and one end of the worm gear 183, and the two pulleys are connected by a belt.

[0029] In this embodiment, the drive shaft 181 is a hollow shaft, and the fixed shaft 182 is located inside the drive shaft 181 and is coaxial with it. The fixed shaft 182 is non-rotatable, while the drive shaft 181 can rotate relative to it. The upper end of the drive shaft 181 is connected to the center area of ​​the bottom of the turntable 2 via a flange, and the rotation of the drive shaft 181 can drive the turntable 2 to rotate. The upper end of the fixed shaft 182 passes through a through hole in the center of the turntable 2 and is connected to the center area of ​​the bottom of the fixed disk 9 located above the turntable 2 via a flange. The fixed disk 9 and the turntable 2 are separated by a certain distance, so the fixed disk 9 will not interfere with the rotation of the turntable 2.

[0030] See Figure 3 A disc 17 is mounted on the end of the worm gear 183 furthest from the synchronous pulley. A photoelectric sensor 20 is located below the disc 17 and is fixedly mounted on a support. Correspondingly, a notch is provided on the disc 17 to cooperate with the photoelectric sensor 20, and this notch is located between the transmitting end and the receiving end of the photoelectric sensor 20.

[0031] As the worm gear 183 rotates, the light emitted from the transmitting end of the photoelectric sensor 20 is blocked by the disk 17, and the receiving end cannot receive the signal. When the notch on the disk 17 rotates into the path of the light, the light passes through the notch and is received by the receiving end, thus triggering the signal of the photoelectric sensor 20. In this way, the number of rotations of the worm gear 183 can be calculated, thereby determining the rotational position of the turntable 2.

[0032] The positioning fixtures 3 on the turntable 2 are evenly distributed along the circumference. Therefore, the rotational distance between two adjacent positioning fixtures 3 is proportional to the integer number of rotations of the worm gear 183. For example, for every rotation of the worm gear 183, the turntable 2 will rotate by a certain angle, and the circumference length corresponding to this angle is the rotational distance between two adjacent positioning fixtures 3.

[0033] like Figure 5 As shown, the first feeding mechanism 4 and the second feeding mechanism 5 serve as the starting process for assembling the battery cover assembly. The two feeding mechanisms have the same structure and are used for feeding the positive electrode assembly 25 and the negative electrode assembly 26, respectively. Both the first feeding mechanism 4 and the second feeding mechanism 5 are fixedly mounted on the frame.

[0034] See Figure 6 The first feeding mechanism 4 mainly consists of a hopper 42, a material box 43, and a multi-axis robot arm. The material box 43 is placed below the multi-axis robot arm 41, and the hopper 42 is located on one side of the material box 43. The discharge chute of the hopper 42 extends above the material box 43. The hopper 42 contains a positive electrode component 25 or a negative electrode component 26, which flows into the material box 43 along the discharge chute.

[0035] The multi-axis robotic arm 41 is a spider robotic arm, which is equipped with a suction cup 804. The spider robotic arm can control the suction cup 804 to move and rotate at any position. The suction cup 804 is connected to a negative pressure mechanism, which draws a vacuum through the adsorption mechanism and uses the suction cup 804 to pick up the positive electrode component 25 or the negative electrode component 26.

[0036] During loading, the multi-axis robot 41 in the first loading mechanism 4 first places the positive electrode component 25 onto the positioning fixture 3 on the turntable 2, which is directly opposite the first loading mechanism 4. Then, the turntable 2 rotates at an angle, causing the positioning fixture 3 to be rotated and conveyed to the position of the second loading mechanism 5. Next, the multi-axis robot 41 in the second loading mechanism 5 places the negative electrode component 26 onto the positioning fixture 3. The positioning fixture 3 has corresponding positioning grooves for positioning the positive electrode component 25 and the negative electrode component 26.

[0037] Once the positive electrode assembly 25 and the negative electrode assembly 26 are placed, the turntable 2 will rotate and transport the positioning fixture 3 to the location of the first leveling unit 6.

[0038] like Figure 7 and Figure 8 As shown, the first leveling unit 6 mainly includes a first support 601, a first pressing cylinder 603, a first pressure plate 604, a first left positioning mechanism 61, and a first right positioning mechanism 62. The first pressing cylinder 603 is a sliding cylinder, which is vertically arranged and fixedly mounted on the first support 601 by a cylinder fixing block 602. The first pressure plate 604 is connected to the output end of the first pressing cylinder 603, and the first pressing cylinder 603 controls the up and down movement of the first pressure plate 604.

[0039] Multiple round holes are provided on the first pressure plate 604. The positions of the round holes are adapted to the positions of the rivets on the positive electrode assembly 25 and the negative electrode assembly 26. The round holes make way for the rivets.

[0040] The first left positioning mechanism 61 and the first right positioning mechanism 62 are arranged opposite to each other. The first left positioning mechanism 61 is mounted on the first bracket 601, and the first right positioning mechanism 62 is mounted on the fixed plate 9.

[0041] The first left positioning mechanism 61 and the first right positioning mechanism 62 have identical structures. The first left positioning mechanism 61 consists of a first positioning cylinder 611, a first positioning plate 612, a connecting plate, and a guide block 613. The first positioning cylinder 611 is horizontally fixedly mounted on the support plate on the back of the first bracket 601. The connecting plate is connected to the output end of the first positioning cylinder 611, and the guide block 613 is fixed to the front end of the connecting plate. A clearance hole is provided on the first bracket 601 to facilitate the passage of the connecting plate.

[0042] Two first positioning plates 612 are provided, corresponding to the positive electrode assembly 25 and the negative electrode assembly 26 respectively. A through guide hole is formed in the guide block 613, allowing the two first positioning plates 612 to move vertically relative to the guide block 613 via guide rods. The guide rods are slidably connected to the guide holes. A spring (not shown in the figure) is fitted onto each guide rod, located between the first positioning plate 612 and the guide block 613. The spring applies a preload to the first positioning plate 612, ensuring it remains in its initial position when not under pressure.

[0043] The first right positioning mechanism 62 is composed of components such as the second positioning cylinder 621, the second positioning plate 622, the connecting plate, and the guide block 613. Its specific connection method is the same as that of the components of the first left positioning mechanism 61, so it will not be described in detail here.

[0044] The two first positioning plates 612 correspond one-to-one with the two second positioning plates 622 and are arranged opposite each other. The first positioning cylinder 611 and the second positioning cylinder 621 control the first positioning plates 612 and the second positioning plates 622 to move towards each other or away from each other.

[0045] Two second positioning grooves are formed on opposite sides of the first positioning plate 612 and the second positioning plate 622. These second positioning grooves are semi-circular, and their shape matches the shape of the two rivets on the positive electrode assembly 25 or the negative electrode assembly 26. When the first positioning block 1322 and the second positioning block 1322 move downwards and clamp the rivets on the positive electrode assembly 25 and the negative electrode assembly 26, the rivets will embed into the second positioning grooves, achieving positioning. This method can correct the position of the positive electrode assembly 25 and the negative electrode assembly 26 on the positioning fixture 3.

[0046] When the positioning fixture 3, carrying the positive electrode assembly 25 and the negative electrode assembly 26, is rotated and conveyed to the area below the first leveling unit 6, the first positioning cylinder 611 and the second positioning cylinder 621 control the first positioning plate 612 and the second positioning plate 622 to move towards each other. The first positioning plate 612 and the second positioning plate 622 clamp the rivets on the positive electrode assembly 25 or the negative electrode assembly 26. Then, the first pressing cylinder 603 controls the first pressing plate 604 to move downward. The first pressing plate 604 contacts the first positioning plate 612 and the second positioning plate 622, and then presses the first positioning plate 612 and the second positioning plate 622 downward. The positive electrode assembly 25 and the negative electrode assembly 26 also move downward as the first positioning plate 612 and the second positioning plate 622 move downward. When the first positioning plate 612 and the second positioning plate 622 contact the upper surface of the positioning fixture 3, it indicates that the positive electrode assembly 25 and the negative electrode assembly 26 are leveled in place and their heights are consistent.

[0047] After the initial leveling is completed, the positioning fixture 3 will rotate and be conveyed to the location of the support feeding unit 7.

[0048] like Figures 9-10 As shown, the support feeding unit 7 mainly consists of a vibratory plate 21, a linear vibration assembly 22, and a feeding mechanism 71. The discharge port of the vibratory plate 21 is connected to the linear vibration assembly 22, and the discharge port of the linear vibration assembly 22 is connected to the feeding mechanism 71.

[0049] Specifically, the feeding mechanism 71 consists of a fixed frame, a feeding cylinder 712, and a sliding plate 711. The feeding cylinder 712 is horizontally fixed to the fixed frame, and the bottom of the sliding plate 711 is horizontally slidably connected to the slide rail fixed to the fixed frame via a slide rail. The output end of the feeding cylinder 712 is connected to one side of the sliding plate 711. A first positioning groove is formed on the sliding plate 711, and the shape of the first positioning groove is adapted to the shape of the bracket 27.

[0050] One end of the first positioning groove extends to the side of the slide plate 711 closest to the direct vibration assembly 22. After the bracket 27 flows out from the discharge port of the direct vibration assembly 22, it flows into the first positioning groove from the side of the slide plate 711. Then, the feeding cylinder 712 pushes the slide plate 711 toward the side where the bracket gripping mechanism 8 is located, waiting for the bracket gripping mechanism 8 to grip the bracket 27 and place it on the corresponding positioning fixture 3.

[0051] A baffle 713 is provided on the side of the fixed frame near the support gripping mechanism 8. The baffle 713 is used to prevent the slide plate 711 from sliding out of the fixed frame.

[0052] A long plate 715 is provided on the side of the baffle 713 near the direct vibration component 22. As the slide plate 711 moves toward the position of the baffle 713, the long plate 715 always blocks the discharge port of the direct vibration component 22, preventing the bracket 27 from being exposed from the discharge port of the direct vibration component 22. This will prevent interference with the slide plate 711 returning to the docking position with the discharge port of the direct vibration component 22.

[0053] A push cylinder 714 is also provided on the baffle 713. The push cylinder 714 is horizontally fixed on the baffle 713. The output end of the push cylinder 714 is connected to the push rod. The moving direction of the push rod is consistent with the length direction of the first positioning groove. When the slide plate 711 moves into place and is blocked by the baffle 713, the push cylinder 714 will control the push rod to move. The push rod will gradually contact the bracket 27 and push the bracket 27 into the first positioning groove. This can reposition the bracket 27 so that the bracket gripping mechanism 8 can accurately grip the bracket 27.

[0054] Above the fixed frame, there is an upper limit plate 716, which is horizontally fixed to the fixed block. The fixed block is fixed to the side of the fixed frame away from the direct vibration assembly 22 by bolts. The upper limit plate 716 is directly opposite the discharge port of the direct vibration assembly 22, and the lower surface of the upper limit plate 716 is slightly higher than the upper surface of the slide plate 711.

[0055] When the first positioning groove on the slide plate 711 is connected to the discharge port of the direct vibration component 22, the direct vibration component 22 will vibrate the bracket 27 into the first positioning groove. At this time, as the bracket 27 gradually goes deeper into the first positioning groove, the upper limit plate 716 will limit the upper part of the bracket 27 to prevent the bracket 27 from tilting up or falling out of the first positioning groove.

[0056] like Figure 11 As shown, the support gripping mechanism 8 mainly includes a base frame, a first forward and backward moving cylinder 801, a cylinder fixing plate, a first lifting cylinder 802, a mounting block 803, and a suction cup 804. The first forward and backward moving cylinder 801 is horizontally fixed to the base frame, which is fixedly mounted on a fixed plate 9. The cylinder fixing plate is connected to the output end of the first forward and backward moving cylinder 801, and the first lifting cylinder 802 is vertically fixedly mounted on the cylinder fixing plate. The first lifting cylinder 802 is a sliding cylinder, and a fixing plate is mounted on the side of the first lifting cylinder 802. The mounting block 803 is fixedly mounted on the lower end of the fixing plate.

[0057] The mounting block 803 has multiple mounting holes, each of which is fitted with a suction cup 804, which is connected to a negative pressure mechanism. A groove is formed on the lower surface of the mounting block 803, and the suction end of the suction cup 804 extends into the groove.

[0058] When gripping the bracket 27, the first forward and backward moving cylinder 801 controls the suction cup 804 to move directly above the bracket 27. Then, the first lifting cylinder 802 controls the suction cup 804 to move downward, generating negative pressure inside the suction cup 804 to attract the bracket 27. The upper surface of the bracket 27 adheres to the lower surface of the mounting block 803, and the lower surface of the mounting block 803 pre-positions the bracket 27. Then, the first forward and backward moving cylinder 801 and the first lifting cylinder 802 control the suction cup 804 to move, placing the bracket 27 onto the corresponding positioning fixture 3.

[0059] The positive electrode component 25 and the negative electrode component 26 on the positioning fixture 3 will be exposed from the mounting holes on the bracket 27. Correspondingly, multiple through-holes are provided on the mounting block 803. These holes are used to avoid the rivets on the positive electrode component 25 and the negative electrode component 26.

[0060] After the bracket 27 is assembled, the positioning fixture 3 will be rotated and conveyed to the position of the cover plate feeding unit 10.

[0061] like Figures 12-16 As shown, the cover plate feeding unit 10 mainly consists of a fixed frame, a carrier plate 101, a hopper 103, and a pushing mechanism 102. The carrier plate 101 is fixedly installed on the top of the fixed frame, the pushing mechanism 102 is located below the carrier plate 101, and the hopper 103 is installed on the carrier plate 101.

[0062] The hopper 103 consists of two limiting blocks 1031. The two limiting blocks 1031 are arranged opposite each other and are vertically fixed on both sides of the carrier plate 101. A first limiting groove is formed on the opposite side of the two limiting blocks 1031. The first limiting groove is vertically continuous so that the cover plate 28 enters the first limiting groove from the upper end of the limiting block 1031 and then flows out from the bottom of the first limiting groove.

[0063] Several cover plates 28 are stacked between two limiting blocks 1031, and the two ends of the cover plates 28 are respectively embedded into the first limiting grooves on the two limiting blocks 1031.

[0064] See Figure 16 A second limiting groove 1011 is formed in the middle area of ​​the upper surface of the carrier plate 101. The width of the second limiting groove 1011 is adapted to the length of the cover plate 28, and the depth of the second limiting groove 1011 is adapted to the thickness of the cover plate 28. Two limiting blocks 1031 are respectively located above the two sides of the second limiting groove 1011. The cover plate 28 in the hopper 103 will fall downward into the second limiting groove 1011. Generally, the cover plate 28 at the bottom will fall into the second limiting groove 1011.

[0065] like Figure 14 As shown, the pushing mechanism 102 mainly consists of a pushing cylinder 1022, a fixing block, and a pushing block 1023. The pushing cylinder 1022 is horizontally fixedly installed at the bottom of the cylinder fixing seat 1021, which is fixed to the side of the carrier plate 101 away from the positioning fixture 3.

[0066] A slide rail is provided at the bottom of the carrier plate 101, and the fixing block is horizontally slidably connected to the slide rail via a slider. The output end of the pusher cylinder 1022 is connected to the fixing block. A pusher block 1023 is provided on each side of the fixing block, and the pusher block 1023 is fixedly connected to the fixing block by screws.

[0067] The pusher block 1023 extends upward and passes through the clearance hole on the carrier plate 101, extending into the second limiting groove 1011. However, the height of the upper surface of the pusher block 1023 does not exceed the height of the upper surface of the cover plate 28 located in the second limiting groove 1011. The extension direction of the clearance hole on the carrier plate 101 is consistent with the pushing direction of the pusher cylinder 1022.

[0068] The pusher cylinder 1022 controls the pusher block 1023 to move closer to or further away from the positioning fixture 3. When the pusher block 1023 moves, it will push the cover plate 28 located at the bottom of the hopper 103 out of the hopper 103 and move towards the positioning fixture 3, and finally be blocked by the blocking block 104.

[0069] The blocking block 104 is fixedly installed on the side of the carrier plate 101 near the positioning fixture 3 to prevent the cover plate 28 from sliding out of the second limiting groove 1011. The blocking block 104 will block the middle area on one side of the cover plate 28.

[0070] Once the cover plate 28 is in place, the cover plate gripping mechanism 11 will move into place and grip the cover plate 28, and then place the cover plate 28 onto the positioning fixture 3.

[0071] like Figure 17 As shown, the cover plate gripping mechanism 11 mainly consists of a fixed frame, a second forward and backward moving cylinder 111, a cylinder fixing plate, a second lifting cylinder 112, a T-shaped plate 114, and two finger cylinders 113. The second forward and backward moving cylinder 111 is horizontally fixedly mounted on the fixed frame, and its output end is connected to the cylinder fixing plate. The second lifting cylinder 112 is vertically fixedly mounted on the cylinder fixing plate.

[0072] The second lifting cylinder 112 is a sliding cylinder. The T-shaped plate 114 is fixedly mounted on the sliding cylinder, and the sliding cylinder controls the up and down movement of the T-shaped plate 114. Two finger cylinders 113 are vertically fixed on both sides of the T-shaped plate 114, and each finger cylinder 113 has two grippers for gripping the cover plate 28. The two finger cylinders 113 control the grippers to grasp the parts of the cover plate 28 near both ends.

[0073] The second forward and backward moving cylinder 111 controls the finger cylinder 113 to extend forward and move to directly above the cover plate 28 to be grasped on the carrier plate 101. Then, the second lifting cylinder 112 controls the two finger cylinders 113 to move downward. The finger cylinders 113 control the two grippers to close and grasp the cover plate 28. The clearance holes on the carrier plate 101 will provide clearance for the grippers, making it easier for the grippers to clamp the sides of the cover plate 28.

[0074] After the cover plate 28 is grasped, the cover plate grasping mechanism 11 will move the cover plate 28 directly above the positioning fixture 3.

[0075] A second left positioning mechanism 23 and a second right positioning mechanism 24 are respectively provided below the cover plate feeding unit 10 and below the cover plate gripping mechanism 11. Before the cover plate 28 is placed on the positioning fixture 3, the second left positioning mechanism 23 and the second right positioning mechanism 24 will position the positive electrode component 25 and the negative electrode component 26.

[0076] like Figure 12As shown, the structures of the second left positioning mechanism 23 and the second right positioning mechanism 24 are identical. This embodiment uses the left positioning mechanism as an example.

[0077] See Figure 13 The second left positioning mechanism 23 consists of a third positioning cylinder 231, a Y-shaped plate 232, and two third positioning plates 233. The third positioning cylinder 231 is horizontally positioned. The third positioning cylinder 231 in the left positioning mechanism is fixedly mounted on a support plate below the carrier plate 101. The output end of the third positioning cylinder 231 is connected to the Y-shaped plate 232, and the two third positioning plates 233 are horizontally fixed on both sides of the top of the Y-shaped plate 232. The two third positioning plates 233 correspond to the positive electrode assembly 25 and the negative electrode assembly 26, respectively.

[0078] Similarly, the second right positioning mechanism 24 has two fourth positioning plates, and their connection method is the same as that of the second left positioning mechanism 23. The third positioning plate 233 and the fourth positioning plate correspond one-to-one and are arranged opposite each other.

[0079] Two semi-circular third positioning grooves are provided on the opposite sides of the third positioning plate 233 and the second positioning plate 622 (see...). Figure 18 The positioning plates in the second left positioning mechanism 23 and the second right positioning mechanism 24 are at the same horizontal height, and their height is adapted to the height of the rivets on the positive electrode assembly 25 and the negative electrode assembly 26 on the positioning fixture 3. The shape of the third positioning groove is adapted to the shape of the rivet.

[0080] The positioning cylinders in the second left positioning mechanism 23 and the second right positioning mechanism 24 control the third positioning plate 233 and the fourth positioning plate to move towards each other, approaching the rivet, and then clamping the rivet, which will be embedded into the third positioning groove. The semi-circular third positioning groove is used to fine-tune and position the positive electrode component 25 and the negative electrode component 26 relative to the positioning fixture 3, so that the cover plate gripping mechanism 11 can accurately place the cover plate 28 onto the positioning fixture 3, while ensuring that the positive electrode component 25 and the negative electrode component 26 can accurately pass through the mounting holes on the cover plate 28.

[0081] When the cover plate 28 approaches the positive electrode assembly 25 and the negative electrode assembly 26, and the positive electrode assembly 25 and the negative electrode assembly 26 partially pass through the mounting holes on the cover plate 28, the second left positioning mechanism 23 and the second right positioning mechanism 24 will respectively control the third positioning plate 233 and the fourth positioning plate to return to their original positions and move away from the rivets, so that the cover plate 28 can fall onto the positioning fixture 3, and the positive electrode assembly 25 and the negative electrode assembly 26 can completely pass through the mounting holes on the cover plate 28, thus completing the loading and assembly of the cover plate 28.

[0082] After the cover plate 28 is assembled, the positioning fixture 3 will be rotated and conveyed to the location of the second leveling unit 12.

[0083] like Figure 19 As shown, the structure of the second leveling unit 12 is roughly the same as that of the first leveling unit 6, except that it lacks the first left positioning mechanism 61 and the second left positioning mechanism 23. The second leveling unit 12 controls the second pressure plate 123 to move downward through the second pressing cylinder 122, thus flattening the cover plate 28. A circular hole is provided on the second pressure plate 123, and the position of the circular hole is adapted to the position of the rivets on the positive electrode assembly 25 and the negative electrode assembly 26. The circular hole serves to make way for the rivets.

[0084] After the cover plate 28 completes the second leveling, the positioning fixture 3 will be rotated and conveyed to the positions of the first pressing block feeding unit 13 and the second pressing block feeding unit 14.

[0085] like Figure 20 As shown, the first pressing block feeding unit 13 and the second pressing block feeding unit 14 have the same structure and are arranged side by side, respectively for feeding the positive electrode pressing block 29 and the negative electrode pressing block 30.

[0086] See Figure 21 The first pressing block feeding unit 13 mainly includes a vibratory feeder 21, a direct vibration assembly 22, a misalignment adjustment mechanism 132, and a pressing block gripping mechanism 131. The direct vibration assembly 22 is connected to the discharge port of the vibratory feeder 21, the misalignment adjustment mechanism 132 is connected to the discharge port of the direct vibration assembly 22, and the pressing block gripping mechanism 131 is located on one side of the misalignment adjustment mechanism 132. After the pressing block 1324 is conveyed from the vibratory feeder 21, it falls onto the direct vibration assembly 22, and then the direct vibration assembly 22 conveys it to the misalignment adjustment mechanism 132. The misalignment adjustment mechanism 132 rotates and adjusts the placement angle of the pressing block 1324, and then the pressing block gripping mechanism 131 grips it and places it onto the positive electrode assembly 25 or the negative electrode assembly 26 on the positioning fixture 3. The positive electrode assembly 25 and the negative electrode assembly 26 have grooves, and the pressure block 1324 is embedded in the grooves. The rivet passes through the pressure block 1324 upward and is finally riveted to the pressure block 1324.

[0087] like Figure 22 As shown, the misalignment adjustment mechanism 132 mainly consists of a support base, a rotary cylinder 1321, a feed block 1323, a positioning block 1322, and a limiting member 1324. The rotary cylinder 1321 is fixedly installed on the top of the support base, and its output end is connected to the bottom of the positioning block 1322. The rotary cylinder 1321 controls the positioning block 1322 to rotate in the horizontal plane. The feed block 1323 is fixedly installed on the body of the rotary cylinder 1321.

[0088] See Figure 23A circular clearance hole is located in the center of the feed block 1323, and the positioning block 1322 is also circular and is located within the clearance hole. A guide groove 13231 is provided on the feed block 1323, extending from one side of the feed block 1323 into the clearance hole. The guide groove 13231 will connect with the discharge port of the direct vibration assembly 22. A limiting member 1324 is fixed above the guide groove 13231 to prevent the pressure block 1324 from tilting upward and detaching from the guide groove 13231.

[0089] Correspondingly, a feeding groove 13221 is provided on the positioning block 1322, the shape of which is adapted to the shape of the pressing block 1324. Circumvention grooves are provided on both sides of the feeding groove 13221 to facilitate the pressing block gripping mechanism 131 gripping the pressing block 1324.

[0090] Before feeding, the feeding trough 13221 will dock with the feeding trough 13231, and the pressing block 1324 will be guided by the guide trough 13231 and conveyed to the feeding trough 13221 on the positioning block 1322. Then the rotary cylinder 1321 will control the positioning block 1322 to rotate and adjust the angle of the positioning block 1322. Then the pressing block gripping mechanism 131 will grip the pressing block 1324.

[0091] like Figure 21 As shown, the block gripping mechanism 131 includes two grippers that are controlled to open and close by finger cylinders 113. The finger cylinders 113 are controlled to move horizontally and vertically by a horizontally set cylinder and a vertically set cylinder, respectively. Then, the two grippers are controlled to open and close to grip the block 1324 and place the block 1324 on the positive electrode assembly 25 or the negative electrode assembly 26.

[0092] The two pressing and gripping mechanisms 131 correspond to the positive electrode component 25 and the negative electrode component 26 on the positioning fixture 3, respectively.

[0093] like Figure 20 As shown, a cover plate front and back detection mechanism 31 is also provided on the fixed plate 9. The cover plate front and back detection mechanism 31 is located between the two pressing block gripping mechanisms 131 and is located directly above the corresponding positioning fixture 3.

[0094] The cover plate front and back detection mechanism 31 uses camera vision to detect whether the front and back of the cover plate 28 on the positioning fixture 3 are correctly placed.

[0095] like Figure 1 As shown, after the positive electrode block 29 and the negative electrode block 30 are assembled, the positioning fixture 3 will be rotated and conveyed to the bottom of the unloading gripping mechanism 15.

[0096] The unloading conveyor line 16 is located on one side of the machine 1. The finally assembled battery cover assembly will be picked up by the unloading gripping mechanism 15 and placed on the unloading conveyor line 16 below to complete the unloading.

[0097] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
