Description

Technical Field

[0001] This invention belongs to the field of battery production technology, specifically relating to a battery bottom box coating equipment for energy storage battery module production. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current.

[0003] A battery cell refers to a single electrochemical cell containing positive and negative electrodes, and is generally not used directly. This differs from a battery, which includes a protection circuit and a casing and can be used directly. A lithium-ion rechargeable battery consists of a battery cell and a protection circuit board. Removing the protection circuit board from the rechargeable battery leaves the battery cell. It is the energy storage component of the rechargeable battery. The quality of the battery cell directly determines the quality of the rechargeable battery.

[0004] In the battery manufacturing process, battery cells need to be installed inside the battery casing. The battery casing and cells are mostly fixed together with adhesive. Currently, adhesive is typically applied to the inner wall of the battery casing where the cells are installed using an adhesive applicator. However, during transportation and storage, dust easily adheres to the inner wall of the battery casing, affecting adhesive adhesion. Existing adhesive applicator equipment only has an adhesive application function, which leads to a decrease in adhesive adhesion at the connection between the battery cell and the battery casing due to dust on the casing, affecting the stability of the battery cell within the battery casing. Therefore, this application proposes an adhesive applicator for battery casings used in the production of energy storage battery modules. Summary of the Invention

[0005] The purpose of this invention is to provide a battery box adhesive coating equipment for the production of energy storage battery modules, in order to solve the problem mentioned in the background art that dust easily adheres to the inner wall of the battery box during transportation and storage, affecting the adhesion of adhesive. Existing adhesive coating equipment only has an adhesive coating function, which leads to the problem that dust on the battery box will reduce the adhesion of adhesive at the connection between the battery cell and the battery box, affecting the stability of the battery cell in the battery box.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery base box gluing equipment for energy storage battery module production, comprising a conveying device, a dust pump, a gluing mechanism, and a three-axis moving platform. The conveying device is used to transport the battery base box, and the three-axis moving platform can move along the X, Y, and Z axes. The adhesive application mechanism is used to apply adhesive to the inner wall of the battery box to fix the battery cells, and the three-axis moving platform is used to move the adhesive application mechanism to the inner wall of the battery box or to move the adhesive application mechanism away from the battery box. The three-axis moving platform is equipped with a suction pipe connected to a dust pump. When the dust pump is started, the dust on the inner wall of the bottom of the hole in the battery box used to install the battery cell can be sucked away through the suction pipe. The three-axis moving platform is equipped with a lifting plate for installing a dust pump and an adhesive applicator.

[0007] Preferably, the conveying device is provided with two baffles to prevent the battery base box from falling off the conveying device, and the two baffles are respectively located on both sides of the battery base box.

[0008] Preferably, a plurality of equally spaced bottom box guide mechanisms are provided on one side of the two baffles.

[0009] Preferably, the bottom box guiding mechanism includes a guide wheel abutting against the outer wall of the battery bottom box, a wheel frame rotatably cooperating with the guide wheel, a mounting seat mounted on the baffle and rotatably cooperating with the wheel frame, and an elastic component that allows the wheel frame to rotate around the mounting seat toward the side closer to the battery bottom box.

[0010] Preferably, the bottom box guide mechanism further includes a limiting plate disposed on the mounting base for limiting the rotation angle of the mounting base.

[0011] Preferably, the baffle is provided with a power bracket connected to the baffle by bolts, a clamping power unit mounted on the power bracket, and a clamping seat connected to the clamping power unit.

[0012] Preferably, the side of the clamping seat away from the clamping power unit mates with the outer wall of the battery base box.

[0013] Preferably, an intermediate plate is provided on the upper side of the conveying equipment, which is parallel to the conveying equipment. The intermediate plate is matched with the groove at the bottom of the battery box, and a heating unit is provided on the intermediate plate.

[0014] Preferably, the intermediate plate is provided with a plurality of storage slots for storing heating units.

[0015] Preferably, the conveying device is provided with two support frames located at both ends of the intermediate plate for fixing the intermediate plate.

[0016] Beneficial effects: I. The present invention provides a battery bottom box gluing device for energy storage battery module production. The outer wall of the dust suction pipe is spaced from the inner wall of the battery bottom box for installing battery cells. When the dust suction pump is started, the dust on the bottom inner wall of the battery bottom box for installing battery cells can be sucked away through the dust suction pipe. In this way, the dust adhering to the battery bottom box is removed in advance before the gluing mechanism applies the glue. Then, the glue is applied to the battery bottom box by the three-axis moving platform and the gluing mechanism. Then, the battery cells are pressed on the applied glue. After the glue cures, the battery cells can be fixed to the battery bottom box by the glue. The contact area between the fixed battery cells and the battery bottom box is large, and the cured battery cells are more stable.

[0017] II. The present invention provides a battery base box gluing device for energy storage battery module production. When the clamping power unit is activated, it can drive the clamping seat to move. When the two clamping power units located on the two baffles are activated, they can drive the two clamping seats to move closer or further apart. When the two clamping seats move closer together, they can clamp the battery base box. This can stabilize the position of the battery base box when the dust pump and gluing mechanism perform dust suction and gluing operations on the battery base box, and avoid collisions between the dust pump, gluing mechanism and other components and the battery base box. After being fixed by the clamping seats and other components, the battery base box is stable in position during gluing, the accuracy of the gluing mechanism is improved, and the battery cell installation is more secure.

[0020] 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.

[0021] Example 1

[0022] like Figure 1-4 As shown, a battery base box gluing equipment for energy storage battery module production includes a conveying device 1, a dust pump 9, a gluing mechanism 11, and a three-axis moving platform 12. The conveying device 1 is used to transport the battery base box 2, and the three-axis moving platform 12 can move along the X, Y, and Z axes. The adhesive application mechanism 11 is used to apply adhesive to the inner wall of the battery base box 2 for fixing the battery cells. The three-axis moving platform 12 is used to move the adhesive application mechanism 11 to the inner wall of the battery base box 2 or to remove the adhesive application mechanism 11 from the battery base box 2. The adhesive application mechanism 11 applies adhesive to the battery base box 2, and then presses the battery cells onto the applied adhesive. After the adhesive cures, the battery cells are fixed to the battery base box 2. After the adhesive cures, it can conduct heat, which can transfer the heat generated by the battery cells during operation to the battery base box 2. The heat transfer is completed through the interaction between the battery base box 2 and the outside air.

[0023] The three-axis moving platform 12 is equipped with a suction pipe 8 connected to the suction pump 9. When the suction pump 9 is started, the dust on the bottom inner wall of the hole in the battery box 2 used for installing the battery cell can be sucked away through the suction pipe 8. The three-axis moving platform 12 is equipped with a lifting plate 10 for installing the suction pump 9 and the glue application mechanism 11.

[0024] Example 2

[0025] Based on Embodiment 1, an intermediate plate 13 is provided on the upper side of the conveying device 1, which is parallel to the conveying device 1. The intermediate plate 13 is matched with the groove at the bottom of the battery base box 2. Several storage slots for storing heating units 15 are provided in the intermediate plate 13. Two support frames 14 are provided on the conveying device 1, which are located at both ends of the intermediate plate 13 to fix the intermediate plate 13. The heating unit 15 adopts a heating resistance wire structure. When the heating unit 15 is activated, it can heat the battery base box 2, thereby keeping the glue applied to the inner wall of the battery base box 2 in a liquid state, thus delaying the curing time of the glue and facilitating the subsequent assembly of the battery cells.

[0026] Example 3

[0027] like Figures 1-8 As shown in the figure, an embodiment of the present invention provides a battery bottom box gluing equipment for energy storage battery module production, including a conveying device 1, a dust pump 9, a gluing mechanism 11, and a three-axis moving platform 12. The conveying device 1 is used to transport the battery bottom box 2. The conveying device 1 adopts a belt conveyor with a frame. The three-axis moving platform 12 can adopt a common three-axis robot, which can perform movement in three directions: X, Y, and Z. It is mainly used to drive the dust pump 9 and the gluing mechanism 11 to move.

[0028] Specifically, the glue application mechanism 11 is used to apply glue to the inner wall of the battery base box 2 to fix the battery cells, and the three-axis moving platform 12 is used to move the glue application mechanism 11 to the inner wall of the battery base box 2 or to remove the glue application mechanism 11 from the battery base box 2.

[0029] In order to prevent the battery base box 2 from detaching from the conveying equipment 1, two baffles 3 are provided at the conveying equipment 1 to prevent the battery base box 2 from falling off the conveying equipment 1. The two baffles 3 are located on both sides of the battery base box 2, and several base box guide mechanisms 4 are provided on the opposite side of the two baffles 3.

[0030] For details, please refer to Figure 5 The bottom box guide mechanism 4 includes a guide wheel 401 abutting against the outer wall of the battery bottom box 2, a wheel frame 402 rotatably cooperating with the guide wheel 401, a mounting seat 403 mounted on the baffle 3 and rotatably cooperating with the wheel frame 402, and an elastic component 404 that allows the wheel frame 402 to rotate around the mounting seat 403 toward the side closer to the battery bottom box 2. The wheel frame 402 is tilted to one side and tilted toward the side of the battery bottom box 2 traveling direction. The elastic component 404 can be a common torsion spring or spring.

[0031] It should be noted that the bottom box guide mechanism 4 also includes a limiting plate 405 set on the mounting base 403 to limit the rotation angle of the mounting base 403. The limiting plate 405 is a straight plate and is located on the rotation path of the wheel frame 402. It can prevent the rotation angle between the wheel frame 402 and the mounting base 403 from being too large, so that the wheel frame 402 is always tilted towards the side of the battery bottom box 2 in the direction of travel.

[0032] To prevent dust on the inner wall of the battery box 2 from affecting the adhesion of the adhesive, a suction pipe 8 connected to the suction pump 9 is provided at the three-axis moving platform 12. There is a gap between the outer wall of the suction pipe 8 and the inner wall of the hole in the battery box 2 used for installing the battery cell. When the suction pump 9 is started, the dust on the bottom inner wall of the hole in the battery box 2 used for installing the battery cell can be sucked away through the suction pipe 8.

[0033] Specifically, the three-axis moving platform 12 is equipped with lifting plates 10 for mounting the dust pump 9 and the glue application mechanism 11, which can be referred to as... Figure 7 .

[0034] In order to keep the position of the battery base box 2 stable when using the vacuum pump 9 and the glue application mechanism 11, a power bracket 6 connected to the baffle 3 by bolts, a clamping power unit 5 installed on the power bracket 6, and a clamping seat 7 connected to the clamping power unit 5 are provided at the baffle 3. The side of the clamping seat 7 away from the clamping power unit 5 cooperates with the outer wall of the battery base box 2.

[0035] When the clamping power unit 5 is activated, it can drive the clamping seat 7 to move. The two clamping power units 5 located on the two baffles 3 are activated, which can drive the two clamping seats 7 to move closer or further apart. When the two clamping seats 7 move closer together, they can clamp the battery base box 2. This can stabilize the position of the battery base box 2 when the vacuum pump 9 and the glue application mechanism 11 are performing vacuuming and glue application operations on the battery base box 2, and prevent the vacuum pump 9, the glue application mechanism 11 and other components from colliding with the battery base box 2, or the battery base box 2 from shifting during glue application, which would cause the glue application point to change, and thus prevent the battery cells from making sufficient contact with the glue during subsequent installation, resulting in the battery cells not being installed securely.

[0036] To prevent the adhesive applied by the coating mechanism 11 from curing before the battery cells are installed, an intermediate plate 13 is provided on the upper side of the conveying equipment 1, parallel to the conveying equipment 1. The intermediate plate 13 fits into the groove at the bottom of the battery base box 2. The intermediate plate 13 has several storage slots for storing the heating unit 15. The conveying equipment 1 has two support frames 14 located at both ends of the intermediate plate 13 for fixing the intermediate plate 13. The heating unit 15 adopts a heating resistance wire structure. When the heating unit 15 is activated, it can heat the battery base box 2, thereby keeping the adhesive applied to the inner wall of the battery base box 2 in a liquid state, thus delaying the curing time of the adhesive and facilitating the subsequent assembly of the battery cells.

[0037] In summary, this invention provides a battery base box gluing device for energy storage battery module production. The outer wall of the suction pipe 8 is spaced from the inner wall of the battery base box 2 where the cells are installed. When the suction pump 9 starts, the suction pipe 8 removes dust from the bottom inner wall of the cells in the battery base box 2. This removes dust adhering to the battery base box 2 before the gluing mechanism 11 applies the glue. Then, the three-axis moving platform 12 and the gluing mechanism 11 apply the glue to the battery base box 2. The cells are then pressed onto the applied glue. After the glue cures, the cells are fixed to the battery base box 2. This results in a larger contact area between the fixed cells and the battery base box 2, making the cured cells more stable.

[0038] When the clamping power unit 5 is activated, it can drive the clamping seat 7 to move. The two clamping power units 5 located on the two baffles 3 are activated, which can drive the two clamping seats 7 to move closer or further apart. When the two clamping seats 7 move closer together, they can clamp the battery base box 2. This can stabilize the position of the battery base box 2 when the vacuum pump 9 and the glue application mechanism 11 are performing vacuuming and glue application operations on the battery base box 2, and prevent the vacuum pump 9, the glue application mechanism 11 and other components from colliding with the battery base box 2. After being fixed by the clamping seats 7 and other components, the battery base box 2 is stable in position during glue application, the glue application accuracy of the glue application mechanism 11 is improved, and the battery cell installation is more secure.

[0039] When the heating unit 15 is activated, it can heat the battery base box 2, thereby keeping the adhesive applied to the inner wall of the battery base box 2 in a liquid state, thus delaying the curing time of the adhesive and facilitating the subsequent assembly of the battery cells.

[0040] 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.
