[0002] With the rapid development of new energy technologies, solid-state batteries, as a new type of battery with high energy density and high safety performance, have received widespread attention. Through a separatorless stacked design, battery energy density can be further improved. In the production process of separatorless lithium-ion batteries, the coating effect of the positive electrode sheet is crucial; poor coating can cause short circuits. Current technologies typically involve applying adhesive to the edges of the positive electrode sheet.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Please refer to Figures 1-10 , Figure 1 This is a structural schematic diagram of an electrode lamination and bonding device provided by this utility model. Figure 1As shown, the electrode lamination and bonding equipment includes a feeding mechanism 1, a bonding mechanism 2, a stacking mechanism 3, and a conveying mechanism 4. The feeding mechanism 1 is used to place the battery electrodes 7. The electrodes 7 include positive and negative electrodes. There can be two feeding mechanisms 1, one for placing several positive electrodes and the other for placing several negative electrodes. The number of feeding mechanisms 1 can be selected as needed; one or more can be set. The bonding mechanism 2 includes a positioning platform 21 and a bonding device 22. The positioning platform 21 has a first station and a second station. The first station is the position where the positioning platform 21 feeds the electrodes 7 to be bonded, and the second station is the position where the positioning platform 21 unloads the bonded electrodes 7. Optionally, the first station is located at one end of the bonding mechanism 2 near the feeding mechanism 1, and it is used to place the positive or negative electrodes transferred from the feeding mechanism 1. The feeding mechanism 1 is located at one end of the bonding mechanism 2 at the first station. The second station is located at one end of the adhesive application mechanism 2 near the stacking mechanism 3, and is used to place the electrode sheet 7 with the adhesive tape 5 applied. During the movement of the positioning platform 21 from the first station to the second station, the adhesive application device 22 applies adhesive to the electrode sheet 7. The stacking mechanism 3 includes a stacking platform 31. The stacking platform 31 is used to sequentially place positive and negative electrode sheets to form a stacked battery cell. The conveying mechanism 4 includes a first transfer mechanism 41 and a second transfer mechanism 42. The first transfer mechanism 41 is used to pick up the electrode sheet 7 from the feeding mechanism 1 and convey it to the positioning platform 21 located at the first station. The second transfer mechanism 42 is used to pick up the positive and negative electrode sheets with the adhesive tape 5 applied from the positioning platform 21 located at the second station and stack them sequentially on the stacking platform 31.

[0034] The actual working process is as follows: The positive and negative electrode sheets are placed into their respective feeding mechanisms 1; the robotic arm 403 of the first transfer mechanism 41 places the electrode sheet 7 to be glued onto the positioning platform 21 at the first station of the gluing mechanism 2; the gluing mechanism 2 starts operating, and the positioning tray 202 of the positioning platform 21 moves forward, passing through the glue roller 222 of the gluing device 22 to apply the adhesive tape 5 onto the negative and positive electrode sheets; the positioning tray 202 of the positioning platform 21 continues to move forward, and when it reaches the second station, the robotic arm 403 of the second transfer mechanism 42 picks up the positive and negative electrode sheets with the adhesive tape 5 pasted on them, and stacks them sequentially on the stacking platform 31; during the stacking process, the first layer is the negative electrode sheet, then the positive electrode sheet, and so on, with the last layer being the negative electrode sheet, ultimately forming the stacked battery cell 8. When the last layer of negative electrode sheets passes through the gluing mechanism 2, the glue roller 222 is controlled to rise, so that the last layer of negative electrode sheets is not covered with adhesive tape 5.

[0035] This utility model provides an electrode lamination and bonding equipment, which has the advantages of simple operation and high practicality. This equipment enables large-scale mass production, improves bonding efficiency, ensures bonding quality, and saves on tooling and labor costs. It is understood that since each layer of electrode 7 is covered with adhesive tape, adjacent electrodes can be attached and fixed during lamination using the tape, thus eliminating the need for a diaphragm in the traditional lamination process and ensuring proper electrode misalignment.

[0036] like Figure 1 As shown, the electrode lamination and bonding equipment provided by this utility model also includes a base 6. The feeding mechanism 1, bonding mechanism 2, lamination mechanism 3, and conveying mechanism 4 are all fixedly installed on the base 6 and are generally arranged in a "U" shape. Optionally, there are two feeding mechanisms 1, namely a positive electrode feeding mechanism 11 and a negative electrode feeding mechanism 12. A first transfer mechanism 41 is fixedly installed on one side of the positive and negative electrode feeding mechanisms. A bonding mechanism 2 is fixedly installed on each side of the positive and negative electrode feeding mechanisms. The two bonding mechanisms 2 are the positive electrode bonding mechanism and the negative electrode bonding mechanism, respectively. The first station of the positioning platform 21 of the two bonding mechanisms 2 is close to the first transfer mechanism 41. A second transfer mechanism 42 is fixedly installed at the other end of the two bonding mechanisms 2. The lamination mechanism 3 is located between the two bonding mechanisms 2 and the second transfer mechanism 42. This fixed installation structure has the advantages of compact location and small space occupation, and can reduce the conveying stroke of the electrode 7, improving production efficiency.

[0037] In one specific implementation, such as Figure 1 As shown, the adhesive application mechanism 2 includes a positive electrode adhesive application mechanism and a negative electrode adhesive application structure arranged parallel to each other along a first direction. The feeding mechanism 1 and the stacking mechanism 3 are located between the positive electrode adhesive application mechanism and the negative electrode adhesive application structure. A first transfer mechanism 41 and a second transfer mechanism 42 are arranged parallel to each other along a second direction. The first transfer mechanism 41 reciprocates between the feeding mechanism 1 and the first workstation, and the second transfer mechanism 42 reciprocates between the stacking mechanism 3 and the second workstation. The first direction is parallel to the tape conveying direction of the adhesive application mechanism 2, and the second direction is perpendicular to the tape conveying direction.

[0038] In one specific implementation, such as Figure 2As shown, the feeding mechanism 1 includes a support block 101, a vertical moving platform 102, an electrode tray 103, and a lifting tray 104. The electrode tray 103 and the lifting tray 104 are drivenly connected to the vertical moving platform 102. The vertical moving platform 102 controls the lifting tray 104 to rise or fall. The lifting tray 104 is used to place positive and negative electrode sheets. A motor or cylinder (not shown) is installed on the lifting tray 104 to control its movement. Several limiting posts (or fences) extend from the periphery of the electrode tray 103, and the lifting tray 104 is located within these limiting posts (or fences). These limiting posts (or fences) guide and limit the lifting tray 104 and the electrode sheets 7 placed on it, preventing misalignment. The electrode tray 103 can be fixed, while the lifting tray 104 is located inside the electrode tray 103 and can move up and down to ensure that the topmost electrode 7 placed on the lifting tray 104 always maintains the same height position, so as to facilitate the robotic arm to grasp the electrode 7. It should be understood that the feeding mechanism 1 is not limited to the above structure, and can also be other common feeding devices, which can be selected and used by those skilled in the art as needed.

[0039] Figure 3 The diagram shows the structure of the adhesive application mechanism 2 in the electrode lamination equipment. Figures 3-6 As shown, the adhesive applicator 2 includes a positioning platform 21 and an adhesive applicator 22. The positioning platform 21 includes a support frame 201, a positioning tray 202, and a tray movement control device 203. The positioning tray 202 is slidably mounted on the support frame 201 via a slide rail 204. The tray movement control device 203 is mounted below the positioning tray 202 and fixed to the support frame 201. The tray movement control device 203 is used to control the positioning tray 202 to move from a first station to a second station. The tray movement control device 203 uses a motor and a lead screw to control the movement of the positioning tray 202. The tray movement control device 203 can also use other drive methods, such as cylinders. Optionally, the tray movement control device 203 uses a high-precision stepper motor to more accurately control the movement of the positioning tray 202.

[0040] In one specific implementation, see also Figure 8The positioning platform 21 also includes an electrode carrier plate 205. The electrode carrier plate 205 is detachably mounted on the positioning tray 202. The electrode carrier plate 205 and the positioning tray 202 can be installed using bolts, snap-fit ​​fasteners, adhesive bonding, or other methods. The electrode carrier plate 205 has an electrode receiving position 206, which is used to place the electrode 7 and limit and fix its position. A vacuum hole 207 is provided at the electrode receiving position 206. By drawing a vacuum through the vacuum hole 207, a negative pressure is created, which adsorbs and fixes the electrode 7, preventing displacement of the electrode 7 during the application of the adhesive tape 5 and ensuring consistent tape adhesion. To reduce device cost and simplify the manufacturing process, the electrode carrier plate 205 adopts a split-type structural design.

[0041] Specifically, such as Figure 8 As shown, the electrode carrier 205 includes a base plate and a support carrier. The support carrier is fixedly mounted on the base plate. Several vacuum holes 207 are provided on the support carrier. A vacuum chamber is provided inside the base plate, and support blocks are provided at the edges or corners of the vacuum chamber. The support blocks support the support carrier, forming a vacuum chamber between the bottom surface of the support carrier and the inner surface of the base plate. A vacuum extraction port 208 is provided on the side of the base plate, communicating with the vacuum chamber. All the vacuum holes 207 are connected to the vacuum chamber, and the vacuum extraction port 208 can be connected to external vacuum equipment, such as a vacuum pump. Of course, the electrode carrier 205 can also adopt other methods or structures to achieve its fixation of the electrode 7.

[0042] like Figure 4 and Figure 5 As shown, the adhesive applicator 22 includes an adhesive feeding roller 221, an adhesive pressure roller 222, an adhesive take-up roller 223, and an adhesive pressure roller adjusting device 224. The adhesive feeding roller 221 and the adhesive take-up roller 223 are used to wind and place the adhesive tape 5. The height of the adhesive feeding roller 221 and the adhesive take-up roller 223 is slightly higher than the height of the adhesive pressure roller 222. The adhesive pressure roller adjusting device 224 is used to adjust the position of the adhesive pressure roller 222 so that the adhesive tape 5 is squeezed and bonded to the positive and negative electrode sheets. Both the adhesive feeding roller 221 and the adhesive take-up roller 223 are equipped with a drive motor 225, and the two drive motors 225 are used to drive the adhesive feeding roller 221 and the adhesive take-up roller 223 to rotate respectively. Optionally, the adhesive feeding roller 221 and the adhesive take-up roller 223 can also share a single drive motor. When the drive motor 225 operates, the tape 5 moves position as the dispensing roller 221 and the receiving roller 223 rotate. When it moves below the pressure roller 222, it contacts the electrode 7 on the electrode carrier plate 205. At this time, due to the pressure of the pressure roller 222, the tape 5 adheres to the surface of the electrode 7. In this invention, the tape 5 is an annular tape, which can be adhered to the periphery of the positive or negative electrode. The tape 5 has an annular frame, and when the adhesive applicator 2 applies adhesive to the electrode 7, the inner edge of the annular frame partially overlaps with the outer edge of the electrode 7.

[0043] like Figure 9 As shown, the stacking mechanism 3 includes a stacking platform 31 and a lifting device 32. The lifting device 32 uses a motor or cylinder to drive the stacking platform 31 to move up and down, thereby controlling the height of the stacking platform 31. The height of the stacking platform 31 is coordinated with the height of the robotic arm of the second transfer mechanism 42. After stacking is completed, the stacking platform 31 can be raised by the lifting device 32 to facilitate the removal of the stacked battery cells 8. Optionally, a stacked battery cell support platform is provided on the stacking platform 31. The stacked battery cell support platform has vacuum holes to limit and fix the stacked battery cells 8 through vacuum adsorption. Its specific structure is similar to that of the aforementioned electrode carrier plate 205.

[0044] like Figure 10 As shown, the first transfer mechanism 41 and the second transfer mechanism 42 have similar structures, differing only in their installation positions. Both the first transfer mechanism 41 and the second transfer mechanism 42 include a transfer platform 401, a robotic arm moving device 402, and a robotic arm 403. The robotic arm moving device 402 controls the position of the robotic arm 403, enabling it to move. Optionally, the first transfer mechanism 41 is located at one end of the adhesive application mechanism 2 at the first station, offset from the feeding mechanism 1. The second transfer mechanism 42 is located at the other end of the adhesive application mechanism 2 at the second station, offset from the stacking mechanism 3. The robotic arm moving device 402 uses a motor and lead screw structure to drive the robotic arm 403. It should be understood that the robotic arm moving device 402 can also use other driving methods, such as cylinders. The robotic arm 403 includes a cylinder 404 and a suction cup 405. The robotic arm 403 uses the suction cup 405 to pick up and place the electrode sheet 7.

[0045] This utility model also provides a stacked battery cell, suitable for preparation using the electrode lamination and bonding equipment described above. The stacked battery cell includes at least one positive electrode coated with a solid electrolyte and at least one negative electrode coated with a solid electrolyte; wherein the positive and negative electrode sheets are alternately stacked. During the stacking process, the first layer is a negative electrode sheet, followed by a positive electrode sheet, and so on, until the last layer is a negative electrode sheet. When the last negative electrode sheet passes through the bonding mechanism 2, the adhesive roller 222 is raised to prevent the adhesive tape 5 from being applied to the last negative electrode sheet; after the electrode stacking is completed, the stacked battery cell 8 is obtained.

[0046] This utility model provides an electrode lamination and stacking equipment that can significantly improve the consistency of adhesive application and stacking, and increase adhesive application efficiency to meet mass production requirements. The equipment has a simple structure, is easy to operate, and is highly practical, saving on tooling and labor costs.

[0047] The stacked battery cells produced by the equipment provided by this utility model have the advantages of consistent adhesive application and stacking, as well as high quality.
