Description

Technical Field

[0001] This invention relates to the field of lithium battery production technology, and more specifically to a lithium battery production assembly equipment and assembly method. Background Technology

[0002] Lithium-ion batteries are a type of secondary battery that uses lithium metal or lithium alloy as the negative electrode and a non-aqueous electrolyte solution. They are classified into various types according to their shape, including square, pouch, and cylindrical. Among them, cylindrical lithium-ion batteries are widely used in power battery packs and energy storage battery packs in new energy vehicles, energy storage systems, and consumer electronics due to their mature manufacturing process, good cell uniformity, high mechanical strength, excellent heat dissipation performance, and relatively low cost.

[0003] When assembling multiple cylindrical lithium battery cells into modules or battery packs, mechanical fixing is required to ensure positional stability between cells, resist vibration and impact, and meet welding precision requirements. Adhesive bonding is one of the widely used methods: compared to mechanical structures such as plastic brackets and metal clips, adhesive can effectively fill the line contact gaps between cylindrical cells, forming surface contact fixing and improving structural strength; at the same time, it eliminates the need for additional structural components, which helps to improve volumetric energy density, simplify module structure, reduce material costs, and allows for improved thermal management and insulation reliability through the selection of thermally conductive or insulating adhesives.

[0004] In existing technologies, the adhesive bonding of cylindrical lithium battery cells is mostly done manually or semi-automatically. This involves an operator using a hand-held adhesive applicator to apply adhesive to the side of the vertically or inclined cell and then bonding them one by one. This method has the following drawbacks: First, it is cumbersome and inefficient, making it difficult to meet the needs of mass production. Second, during adhesive application, the adhesive flows downwards along the cell surface due to gravity, easily causing unintended adhesion at the bottom, affecting subsequent installation. Third, during manual bonding, the pressing angle, force, and positioning reference are unstable, easily leading to misalignment between cells, such as non-parallel axes and inconsistent end-face heights, which in turn causes misalignment and reduced welding quality during subsequent busbar welding. Summary of the Invention

[0005] This invention provides a lithium battery production and assembly equipment and assembly method, which can solve the problems of cumbersome operation, low efficiency, glue dripping causing pollution, and bonding misalignment affecting welding quality in the prior art.

[0006] The objective of this invention can be achieved through the following technical solutions: The first aspect of this invention provides a lithium battery production and assembly equipment, including an assembly box.

The square tube is connected to the end of the support column, the inverted L-shaped column is slidably inserted into the square tube, the stop block is in contact with the bottom end of the square tube, and the stop block is connected to the bottom end of the inverted L-shaped column. The pressure block is fitted on the inverted L-shaped column near the top end, and the second spring is fitted on the inverted L-shaped column and installed between the square tube and the pressure block.

[0010] As a further aspect of the present invention: the positioning component includes an arc-shaped pressure plate and a strip roller. The arc-shaped pressure plate is connected to the end of the inverted L-shaped column and is located directly above the cylindrical battery. The strip roller is rotatably mounted on the top of the arc-shaped pressure plate.

[0011] As a further embodiment of the present invention: the lifting and traversing mechanism includes a gantry frame, an electric guide rail with a guide sleeve, an electric slider, an extension rod, a U-shaped frame, and a first cylinder. Two gantry frames are symmetrically installed on the top edge of the assembly box. The electric guide rail is slidably connected to the vertical part of the gantry frame through the guide sleeve. The U-shaped frame is installed between the two guide sleeves. The first cylinder is installed on the top of the gantry frame, and its output end is connected to the U-shaped frame. The electric slider is installed on the electric guide rail, and the extension rod is installed on one side of the electric slider.

[0012] As a further aspect of the present invention: the glue application mechanism includes a horizontal tube, a glue nozzle, and a flexible tube. The horizontal tube has a closed structure at both ends, and the ends of the horizontal tube are connected to an extension rod. The glue nozzle is connected to the bottom of the horizontal tube.

[0013] As a further aspect of the present invention: the driving component includes a housing and a driving roller, the housing is installed inside an assembly box, and a plurality of driving rollers are rotatably installed inside the housing, with the top end of the driving roller abutting against the bottom end of the cylindrical battery.

[0014] As a further aspect of the present invention: the extrusion mechanism includes a sliding frame, a support column, and a second cylinder. The sliding frame has a U-shaped structure and is slidably sleeved with the housing. The support column is connected to the bottom of the sliding frame and is slidably connected to the bottom of the assembly box. The second cylinder is installed at the end of the assembly box, and its output end is connected to the sliding frame.

[0015] A second aspect of the present invention provides a lithium battery production and assembly method, applied to the aforementioned lithium battery production and assembly equipment, comprising the following steps: S1. Push the cylindrical batteries to be bonded one by one into the corresponding carrier through the arc-shaped opening until they can no longer be pushed; S2. Start the lifting and lateral movement mechanism to drive the glue application mechanism to move downward, thereby pressing down the positioning part connected to the elastic support, which can press and position the cylindrical battery. S3. The lifting and traversing mechanism is used to drive the coating mechanism to move along the length of the cylindrical battery, so that the glue discharged by the coating mechanism is applied to the curved side wall of the cylindrical battery along the length. S4. Start the drive unit to rotate the cylindrical battery under the pressure state, so that the glued part on the cylindrical battery is at the same height as its axis. Then start the extrusion mechanism to make the carriers at both ends slide towards each other, so that multiple glued cylindrical batteries are bonded together. Finally, push out the bonded cylindrical batteries through the arc-shaped opening.

[0016] The beneficial effects of this invention are: 1. In this invention, by setting multiple carriers for placing cylindrical batteries inside the assembly box, and installing extrusion mechanisms at both ends of the assembly box to drive the carriers at both ends to slide towards each other, and cooperating with the sliding reset components installed between the carriers and the assembly box, the automatic pressing and bonding of multiple cylindrical batteries after adhesive application and the automatic reset after bonding are realized, replacing the traditional manual one-by-one bonding operation method, and effectively solving the problems of cumbersome and inefficient manual operation in the prior art.

[0017] 2. In this invention, by setting a positioning component for pressing the cylindrical battery above the assembly box, and installing an elastic support component between the positioning component and the bearing component, and cooperating with the driving component installed inside the assembly box for rotating the cylindrical battery after it is pressed, the cylindrical battery is stably pressed and positioned before the adhesive is applied. After the adhesive is applied, the driving component drives the cylindrical battery to rotate, rotating the adhesive part to the same height as the axis. This avoids the adhesive from dripping down the battery surface to the end under the action of gravity, thereby solving the problem of adhesive dripping causing contamination of the bottom of the battery, affecting subsequent installation, and posing safety hazards in the prior art.

[0018] 3. In this invention, a lifting and traversing mechanism is set up to connect the gluing mechanism and the top of the assembly box. When the gluing mechanism is pressed down by the lifting and traversing mechanism, the positioning component is driven to press the cylindrical battery. Under the pressing state, the gluing mechanism is driven to move along the length of the cylindrical battery to complete linear gluing. Then, the position of the gluing surface is adjusted by the rotation of the driving component and the extrusion mechanism is used to make the carrier components slide towards each other to complete the bonding. Throughout the process, the cylindrical battery is always stably constrained by the positioning component, avoiding the relative displacement caused by unstable pressing during manual bonding. This ensures the positional accuracy of the battery module after bonding and solves the problem of welding quality affected by misalignment during subsequent busbar welding.

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] like Figures 1-9As shown, the present invention is a lithium battery production and assembly equipment, including an assembly box 100. The assembly box 100 contains multiple support members 200 for placing cylindrical batteries 10, and a sliding reset member 300 is installed between the support members 200 and the assembly box 100. An arc-shaped opening 101 for the cylindrical batteries 10 to slide out is provided on the top side wall of the assembly box 100. A positioning member 400 for pressing the cylindrical batteries 10 is provided above the assembly box 100. An elastic support member 500 is installed between the positioning member 400 and the support members 200. An adhesive application mechanism 600 is provided above the positioning member 400. A lifting and traversing mechanism 700 is installed between the adhesive application mechanism 600 and the top of the assembly box 100. A driving member 800 is installed inside the assembly box 100 to drive the cylindrical batteries 10 to rotate after being pressed. Extrusion mechanisms 900 are installed at both ends of the assembly box 100 to drive the support members 200 at both ends to slide towards each other.

[0024] It should be noted that, firstly, the cylindrical batteries 10 to be bonded are pushed one by one into the corresponding carriers 200 inside the assembly box 100 through the arc-shaped opening 101 on the top side wall of the assembly box 100, until the cylindrical batteries 10 can no longer be pushed. At this point, the cylindrical batteries 10 are placed on the carriers 200. Then, the lifting and traversing mechanism 700 is activated, which drives the adhesive application mechanism 600 to move downward. During the downward movement, the adhesive application mechanism 600 contacts and presses down on the positioning member 400. The positioning member 400 overcomes the elastic force of the elastic support member 500 and moves downward until the cylindrical batteries 10 are pressed and positioned between the carriers 200 and the positioning member 400. Next, the lifting and traversing mechanism 700 drives the adhesive application mechanism 600 to move downward. The 00 moves along the length of the cylindrical battery 10, causing the adhesive coating mechanism 600 to evenly apply adhesive to the curved sidewalls of the cylindrical battery 10 along its length. After the adhesive coating is completed, the drive component 800 is activated. The drive component 800 drives the cylindrical battery 10 to rotate while the cylindrical battery 10 is being pressed, so that the coated part on the cylindrical battery 10 rotates to the same height as its axis. Subsequently, the extrusion mechanisms 900 at both ends of the assembly box 100 are activated. The extrusion mechanisms 900 drive the carriers 200 at both ends to slide towards each other, so that multiple coated cylindrical batteries 10 are brought closer together and pressed and bonded together. Finally, after bonding is completed, the bonded cylindrical batteries 10 are pushed out through the arc-shaped opening 101, completing the entire assembly process.

[0025] like Figures 3-4 As shown, the support member 200 includes an arc plate 201, an end plate 202, a U-shaped column 203, and a column 204. The end plate 202 is installed between the inner walls of the two arc plates 201 near their ends, and the two arc plates 201 are symmetrically arranged. The U-shaped column 203 is installed on the lower surface of the end of the arc plate 201, and the column 204 is installed at the bottom of the U-shaped column 203.

[0026] It should be noted that two symmetrically arranged arc-shaped plates 201 form an arc-shaped surface supporting the cylindrical battery 10. The end plate 202 limits the end of the cylindrical battery 10. The arc-shaped plates 201 are slidably connected to the assembly box 100 via the U-shaped column 203 and the column 204. In this embodiment, the height of the top of the arc-shaped plate 201 is lower than the height of the axis of the cylindrical battery 10, so that when two adjacent support members 200 approach each other under the drive of the extrusion mechanism 900, the side walls of the two cylindrical batteries 10 will preferentially contact and adhere to each other. After the cylindrical batteries 10 are attached, the two arc-shaped plates 201 remain spaced apart and do not contact each other, thereby avoiding structural interference.

[0027] like Figure 2 and Figure 4 As shown, the sliding reset component 300 includes a protrusion 301, a guide rod 302, and a first spring 303. The protrusion 301 is installed on the side of the column 204 near the inner wall of the assembly box 100, and a first through groove 102 for the protrusion 301 to slide is provided on the side wall of the assembly box 100. The guide rod 302 is installed in the first through groove 102, and the protrusion 301 and the guide rod 302 are slidably connected. The first spring 303 is sleeved on the guide rod 302, and the first spring 303 is installed between the end of the protrusion 301 and the first through groove 102.

[0028] It should be noted that when the protrusion 301 slides along the column 204, it moves along the guide rod 302 in the first through groove 102 and compresses or releases the first spring 303. The sliding reset members 300 on the left and right sides are staggered to avoid interference between the two in the middle when they slide towards each other. In the initial state, the protrusion 301 is attached to the end of the first through groove 102 so that the first spring 303 is kept in a stored state, ensuring that the spring force can immediately push the protrusion 301 to drive the bearing member 200 to automatically reset after the extrusion mechanism 900 is reset.

[0029] like Figure 2 and Figure 5 As shown, the elastic support 500 includes a support column 501, a square tube 502, a second spring 503, a stop block 504, and an inverted L-shaped column 506 with a pressure block 505. The support column 501 is installed on the side of the U-shaped column 203 near the inner wall of the assembly box 100, and a second through groove 103 for sliding of the support column 501 is provided on the side wall of the assembly box 100. The square tube 502 is connected to the end of the support column 501, and the inverted L-shaped column 506 is slidably inserted into the square tube 502. The stop block 504 is attached to the bottom end of the square tube 502 and is connected to the bottom end of the inverted L-shaped column 506. The pressure block 505 is fitted on the inverted L-shaped column 506 near the top end. The second spring 503 is fitted on the inverted L-shaped column 506 and is installed between the square tube 502 and the pressure block 505.

[0030] It should be noted that when the support column 501 slides along the second through groove 103 with the U-shaped column 203, the square tube 502 is connected to the end of the support column 501, and the inverted L-shaped column 506 is slidably inserted into the square tube 502 and its bottom end is limited by the stop block 504. When the lifting and traversing mechanism 700 presses down the positioning member 400, the positioning member 400 drives the inverted L-shaped column 506 to slide downward relative to the square tube 502, so that the pressure block 505 fitted on the inverted L-shaped column 506 compresses the second spring 503, thereby forming an elastic compression on the cylindrical battery 10. When the positioning member 400 releases the pressure, the second spring 503 releases the elastic force to push the inverted L-shaped column 506 to reset. During the sliding process of the bearing member 200, the inverted L-shaped column 506 can move synchronously with the bearing member 200 and maintain a continuous compression state on the cylindrical battery 10.

[0031] like Figure 1 and Figure 5 As shown, the positioning component 400 includes an arc-shaped pressure plate 401 and a strip roller 402. The arc-shaped pressure plate 401 is connected to the end of the inverted L-shaped column 506 and is located directly above the cylindrical battery 10. The strip roller 402 is rotatably mounted on the top of the arc-shaped pressure plate 401.

[0032] It should be noted that the arc-shaped pressure plate 401 is connected to the end of the inverted L-shaped column 506 and located directly above the cylindrical battery 10. It is used to move downward with the inverted L-shaped column 506 when the lifting and traversing mechanism 700 is pressed down, and to press and position against the curved side wall of the cylindrical battery 10. The strip roller 402, which is rotatably mounted on the top of the arc-shaped pressure plate 401, comes into contact with it after the glue application mechanism 600 is pressed down. When the glue application mechanism 600 moves along the length of the cylindrical battery 10 to apply glue, the top part of the glue application mechanism 600 and the top part of the strip roller 402 slide relative to each other, thereby reducing the friction by reducing the contact area. When the carrier 200 moves the cylindrical battery 10 to bond, the strip roller 402 and the glue application mechanism 600 roll relative to each other, further reducing the friction to avoid motion interference.

[0033] like Figures 6-7 As shown, the lifting and traversing mechanism 700 includes a gantry frame 701, an electric guide rail 703 with a guide sleeve 702, an electric slider 704, an extension rod 705, a U-shaped frame 706, and a first cylinder 707. Two gantry frames 701 are symmetrically installed on the top edge of the assembly box 100. The electric guide rail 703 is slidably connected to the vertical part of the gantry frame 701 through the guide sleeve 702. The U-shaped frame 706 is installed between the two guide sleeves 702. The first cylinder 707 is installed on the top of the gantry frame 701, and its output end is connected to the U-shaped frame 706. The electric slider 704 is installed on the electric guide rail 703, and the extension rod 705 is installed on one side of the electric slider 704.

[0034] It should be noted that the first cylinder 707 is installed on the top of the gantry 701 and drives the U-shaped frame 706 connected to its output end to rise and fall. The U-shaped frame 706 drives the guide sleeves 702 on both sides to slide along the vertical part of the gantry 701, thereby enabling the electric guide rail 703 connected to the guide sleeves 702 to achieve the rising and falling movement. The electric slider 704 installed on the electric guide rail 703 drives the extension rod 705 to move laterally along the electric guide rail 703, thereby driving the glue application mechanism 600 to perform a compound movement of rising and falling in the vertical direction and moving laterally in the horizontal direction through the extension rod 705.

[0035] like Figure 1 and Figure 6 As shown, the glue application mechanism 600 includes a horizontal tube 601, a glue nozzle 602, and a flexible tube 603. The horizontal tube 601 has a closed structure at both ends, and the ends of the horizontal tube 601 are connected to the extension rod 705. The glue nozzle 602 is connected to the bottom of the horizontal tube 601.

[0036] It should be noted that the end of the horizontal tube 601 is connected to the extension rod 705, and moves up and down and laterally with the lifting and lateral movement mechanism 700. The hose 603 is connected to the external glue dispensing equipment to deliver glue into the horizontal tube 601 which is closed at both ends. The glue is evenly discharged through the glue outlet 602 connected to the bottom of the horizontal tube 601. In this embodiment, the number of glue outlets 602 is one less than the total number of cylindrical batteries 10, that is, no glue outlet 602 is provided above the cylindrical battery 10 at one end, so that the cylindrical battery 10 at that end does not need to be glued during the glue application process, thus avoiding glue waste.

[0037] like Figure 3 and Figures 8-9 As shown, the drive unit 800 includes a housing 801 and a drive roller 802. The housing 801 is installed inside the assembly box 100, and a plurality of drive rollers 802 are rotatably installed inside the housing 801, with the top end of the drive roller 802 abutting against the bottom end of the cylindrical battery 10.

[0038] It should be noted that in this embodiment, the multiple drive rollers 802 inside the housing 801 can rotate synchronously through sprockets and chains, and one of the drive rollers 802 is driven by a stepper motor whose rotation angle can be controlled. When the cylindrical battery 10 is pressed, the stepper motor starts, driving the drive roller 802 to rotate, and then drives all the drive rollers 802 to rotate synchronously through the sprockets and chains, thereby driving all the cylindrical batteries 10 to rotate synchronously to a preset angle, so that the glued part is at the same height as the axis.

[0039] like Figure 3 and Figures 8-9As shown, the extrusion mechanism 900 includes a sliding frame 901, a support column 902, and a second cylinder 903. The sliding frame 901 has a U-shaped structure and is slidably sleeved with the housing 801. The support column 902 is connected to the bottom of the sliding frame 901 and is slidably connected to the bottom of the assembly box 100. The second cylinder 903 is installed at the end of the assembly box 100, and its output end is connected to the sliding frame 901.

[0040] It should be noted that the sliding frame 901 has a U-shaped structure and is slidably sleeved with the housing 801. The support column 902 is connected to the bottom of the sliding frame 901 and is slidably connected to the bottom of the assembly box 100, which plays a supporting and guiding role in the movement of the sliding frame 901. The second cylinder 903 is installed at the end of the assembly box 100, and its output end is connected to the sliding frame 901. When the second cylinder 903 extends, it drives the sliding frame 901 to slide inward to the inside of the assembly box 100. The sliding frame 901 drives the multiple carriers 200 connected to it to move synchronously towards each other, so that the cylindrical batteries 10 on each carrier 200 approach each other and are pressed and bonded together.

[0041] This invention provides a lithium battery production and assembly method, comprising the following steps: S1. Push the cylindrical batteries 10 to be bonded one by one into the corresponding carrier 200 through the arc-shaped opening 101 until they can no longer be pushed. S2. Start the lifting and horizontal movement mechanism 700 to drive the glue application mechanism 600 to move downward, thereby pressing down the positioning part 400 connected to the elastic support 500, so as to press and position the cylindrical battery 10. S3. Using the lifting and traversing mechanism 700, the glue application mechanism 600 is moved along the length of the cylindrical battery 10, so that the glue exported by the glue application mechanism 600 is applied to the curved side wall of the cylindrical battery 10 along the length. S4. Start the drive unit 800 to rotate the cylindrical battery 10 under the pressure state, so that the glued part on the cylindrical battery 10 is at the same height as its axis. Then start the extrusion mechanism 900 to make the carriers 200 at both ends slide towards each other, so that multiple glued cylindrical batteries 10 are bonded together. Finally, push out the bonded cylindrical batteries 10 through the arc-shaped opening 101.

[0042] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
