Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to an assembly equipment for lithium batteries. Background Technology

[0002] In the production process of lithium batteries, the packaging process is crucial. While existing lithium battery packaging technologies are constantly evolving, there are still some problems to be solved.

[0003] For example, Chinese utility model CN201720141770.7 discloses a lithium battery packaging device, which sets a spring at the bottom of the lifting plate, which to some extent solves the problem of lithium battery deformation and damage caused by excessive sensing pressure. However, this solution has obvious limitations. It can only press and package one lithium battery at a time and cannot package multiple battery packs at the same time. As the application of lithium batteries becomes more and more widespread, the market has put forward higher requirements for the output and efficiency of lithium batteries. In large-scale production, the method of packaging individual batteries one by one is inefficient and cannot meet the growing market demand.

[0004] Therefore, how to simultaneously encapsulate multiple batteries or battery packs while avoiding damage to lithium batteries due to excessive pressure has become a technical problem to be solved in the current field of lithium battery packaging equipment. In view of this, we propose an assembly equipment for lithium batteries that solves the above problem. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figures 1-6A lithium battery assembly device includes a base, a central control panel (not shown) on the side wall of the base, which is electrically connected to various electronic control components in the device. A slide rail 2 is provided on the top of the base 1, and a battery tray 3 is slidably connected to the slide rail 2. Multiple battery placement slots 4 are provided on the top of the battery tray 3. The battery tray 3 moves laterally along the slide rail 2 to sequentially move the battery placement slots 4 under a pressing mechanism 8 for sealing. A first sliding mechanism 5 is provided between the battery tray 3 and the base 1, which can drive the battery... The tray 3 slides on the slide rail 2. A support base 6 is fixedly connected to the top of the slide rail 2 on one side. A displacement groove 7 perpendicular to the slide rail 2 is provided on the bottom surface of the support base 6 above the slide rail 2. A displacement block 10 is slidably connected in the displacement groove 7. The displacement groove 7 provides guidance for the longitudinal movement of the displacement block 10. A second sliding mechanism 9 is provided inside the support base 6. The second sliding mechanism 9 is used to drive the displacement block 10 to move in the displacement groove 7. A pressing mechanism 8 is provided at the bottom of the displacement block 10. The pressing mechanism 8 is used to press and seal the lithium battery in the battery placement slot 4.

[0026] Specifically, on the top of the battery tray, eight battery placement slots 4 are evenly distributed in a direction parallel to the slide rail 2, and two battery placement slots 4 are evenly distributed in a direction perpendicular to the slide rail 2, so that the equipment can simultaneously and orderly encapsulate multiple lithium batteries, thereby improving encapsulation efficiency.

[0027] The first sliding mechanism 5 includes a mounting groove 52 set on the top of the base 1. A first motor 53 is installed in the mounting groove 52. A gear 54 is fixedly connected to the output shaft of the first motor 53. A rack 51 is meshed with one side of the gear 54. The rack 51 is fixedly connected to the bottom of the battery tray and parallel to the slide rail 2. The first motor 53 drives the gear 54 to rotate. Through the meshing transmission between the gear 54 and the rack 51, the rotational motion of the motor is converted into the lateral linear motion of the battery tray 3 on the slide rail 2, thereby achieving precise displacement of the battery tray 3 and moving the battery placement slot 4 sequentially below the pressing mechanism 8.

[0028] Furthermore, the support base 6 has an "L" shaped structure. The support base 6 includes a horizontal support part 61 and a vertical support part 62. The support part 62 is fixedly connected to the top of the slide rail base 1, and the horizontal support part 61 is fixedly connected to the top of the vertical support part 62. The horizontal support part 61 is located above the slide rail 2. The displacement groove 7 is set at the bottom of the horizontal support part 61 to ensure that the pressing mechanism 8 can move above the battery tray 3 to realize the encapsulation operation of lithium batteries in battery placement slots 4 at different positions.

[0029] The second sliding mechanism 9 includes a drive chamber 96 disposed inside the horizontal bearing part 61 and connected to the limiting groove 97. A cam 93 is rotatably connected inside the drive chamber 96. The rotating shaft of the cam 93 passes through the inner wall of the drive chamber 96 and is connected to a second motor 92. The arc surface of the cam 93 is rolled in contact with a U-shaped wheel frame 94. A push rod 95 is fixedly connected to the side wall of the U-shaped wheel frame 94 away from the cam 93. One end of the push rod 95 away from the cam 93 is fixedly connected to the side wall of the displacement block 10. When the second motor drives the cam 93 to rotate, the cam 93 pushes the U-shaped wheel frame, which in turn pushes the cylinder 81 to move in the displacement groove 7 through the push rod 95, so that the pressing mechanism 8 is displaced above the battery placement slots 4 of different rows. A return spring 91 is fixedly connected between the side wall of the displacement block 10 away from the cam 93 and the inner wall of the displacement groove. When the cam 93 rotates back to the initial position, the return spring 91 can pull the displacement block 10, the push rod 95 and the U-shaped wheel frame back to the initial position, preparing for the next packaging operation.

[0030] The inner walls on both sides of the displacement groove 7 are provided with limiting grooves 97, and sliders 98 are movably connected in the limiting grooves 97. The two sliders 98 are fixedly set on both sides of the displacement block 10. The sliders 98 cooperate with the limiting grooves 97 so that the displacement block 10 can slide stably in the displacement groove 7, thereby ensuring the accuracy and stability of the movement of the pressing mechanism 8.

[0031] The pressing mechanism 8 includes a cylinder 81, which is fixedly connected to the bottom of the displacement block 10. A pressing mold 82 is fixedly connected to the bottom of the cylinder 81. The cylinder 81 can drive the pressing mold 82 to move downward to press and seal the lithium battery in the battery placement slot.

[0032] Both ends of the slide rail 2 are movably connected to limit blocks 21. The limit blocks 21 are used to limit the sliding range of the battery tray 3 and prevent the battery tray 3 from sliding off the slide rail 2.

[0033] Working principle: After the equipment is started, the first motor 53 starts working, driving the gear 54 at the output end to rotate. Since the gear 54 is meshed with the rack 51 set at the bottom of the battery tray 3 and parallel to the slide rail 2, the battery tray 3 is driven to move laterally on the slide rail 2 through the transmission of the gear 54 and the rack 51. When the first battery placement slot 4 is below the pressing mechanism 8, the first motor 53 stops. At this time, the pressing mechanism 8 presses and seals the battery in the first battery placement slot 4. The pressing mechanism 8 includes a cylinder 81. The pressing mold 82 at the bottom of the cylinder 81 presses the battery under the drive of the cylinder 81. After the battery in the first battery placement slot 4 is pressed and sealed, the first motor 53 starts again and moves the second battery placement slot 4 to below the pressing mechanism 8. The lateral movement stops again, and the pressing mechanism 8 presses and seals the battery in the second battery placement slot 4. This process is repeated until all the batteries in the first row of horizontal battery placement slots 4 are pressed and sealed.

[0034] Next, the second motor 92 rotates, driving the cam 93 to rotate. The cam 93, through rolling contact with the U-shaped wheel frame 94, pushes the push rod 95 at the front end of the U-shaped wheel frame 94, thereby pushing the displacement block 10 to move in the displacement groove 7. After the pressing mechanism 8 is moved above the longitudinal second row of battery placement slots 4, the second motor 92 stops rotating and self-locks. Then, the first motor 53 moves in the opposite direction intermittently, moving the second row of battery placement slots 4 sequentially below the pressing mechanism 8 to perform the pressing and sealing operation.

[0035] After the second row of batteries is pressed and sealed, the second motor 92 continues to rotate, and the cam 93 returns to its initial position and locks itself. During this process, the reset spring 91 plays a role in pulling the displacement block 10, push rod 95 and U-shaped wheel frame 94 back to their initial positions, preparing for the next sealing operation.

[0036] Throughout the entire process, the coordinated operation of various components enables the simultaneous pressing and packaging of multiple lithium batteries, greatly improving production efficiency and packaging quality.
