Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing, and particularly relates to a battery module self-heating glue curing follow-up device. Background Art

[0002] In the process of battery module production, in order to ensure the structural stability and heat dissipation performance of the module, a bonding process of applying glue to the side plates is often adopted. The glue application quality between the module side plates and the battery cells directly affects the later use performance of the battery module. Glue is applied between the side plates and the battery cells in the module to enhance the bonding strength. In order to prevent the side plates from detaching, a detachable pressing tooling needs to be added to press the side plates, and it is disassembled after the glue is solidified.

[0003] However, at present, after the tooling is disassembled, it is equipped with a separate line body to convey it to the installation station, which is costly and cumbersome to operate. At the same time, for side plate glue heating, a heating room needs to be configured to heat the production line trays as a whole, which occupies a large area. And the trays are continuously heated for about 30 minutes, affecting the production rhythm and being costly. Moreover, the existing heating method often uses infrared heating, and the heating speed is slow.

[0004] For example, in the existing patented technology with the patent publication number CN117199483A and the patent name of a heating, pressurizing and cooling system and method for a battery module, it is disclosed that "the system includes a cooling and standing warehouse, a running trolley, a heating and pressurizing device and a tray assembly. The heating and pressurizing device includes a table board, a side plate heating and pressurizing unit, an end plate fixing unit and a battery cell pole column pressurizing unit. When performing operations, the battery module is limited and fixed on the tray assembly; the running trolley is accurately docked with the heating and pressurizing device, and the tray assembly is pushed to smoothly transition to the table board and locked, so that the battery module can quickly and accurately reach the designated position for heating and pressurizing operations". In this technology, a separate area designated for heating and pressurizing operations is set up, and it is conveyed by a running trolley, which is costly and cumbersome to operate, and setting up a separate heating and pressurizing area occupies a large area.

[0005] For example, in the existing patented technology with the patent publication number CN116689259A and the patent name of a pressing, heating and standing device and method for side plate glue application of a lithium battery module, it is disclosed that "it includes a double-station elevator and a heating and standing machine. The double-station elevator includes an elevator frame, two lifting components symmetrically arranged on the left and right, and a plurality of pressing units. The heating and standing machine includes an electric cabinet, a frame formed by a plurality of heating and standing stations, and a plurality of heating units. The two lifting components are respectively connected to the elevator frame, and each lifting component is provided with a pressing unit. The lithium battery module is placed on the pressing unit and pressed by it. The pressing unit and the lithium battery module are moved into the heating and standing station together. Each heating and standing station is provided with a heating unit, and the electric cabinet is electrically connected to the heating unit". In this technology, a separate heating area is also set up, and it is moved into the heating area by an elevator. At the same time, this technology uses infrared heating, and the heating speed is slow. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: how to solve the problems of cumbersome glue coating and heating operations and high costs for the side plates of battery modules at present.

[0007] To solve the above technical problems, the present invention provides the following technical solutions:

[0008] A self-heating glue curing follow-up device for a battery module, including a line body, on which a self-heating tray is installed, and several groups of lifting positioning charging mechanisms are installed below the line body. When the self-heating tray moves directly above the lifting positioning charging mechanism, it can be charged.

[0009] A bottom plate is installed on the top of the self-heating tray, and a heating pressing mechanism and a workpiece end pressing part are installed on the outside of the bottom plate; a battery assembly is provided at the bottom of the self-heating tray, and a lifting plate and a charging part installed on the lifting plate are provided at the top of the lifting positioning charging mechanism. The lifting plate can lift the charging part to connect it to the battery assembly.

[0010] In this application, a self-heating tray that can move along with the line body is set on the line body, and several groups of lifting positioning charging mechanisms are set at the bottom of the line body to supplement heating power for the self-heating tray moving on the line body, so that the battery module can complete self-heating on the line body without affecting the simultaneous progress of other processes on the line body. The self-heating tray in this application has a built-in heating system during the moving operation, and there is no need to specially configure a heating room. The tray is heated by a thermocouple, which ensures the process temperature. Driving by the line body greatly shortens the drying time of the battery module and reduces the operation process.

[0011] As a further solution of the present invention: the lifting plate and the charging part are integrated on a bottom frame located below the line body, and a driving part for driving the lifting plate to lift towards the self-heating tray directly above is installed on the bottom frame.

[0012] In this application, a lifting plate, a charging part and a driving part are set on the lifting positioning charging mechanism. The driving part drives the lifting plate to lift, and then the charging part on the lifting plate is driven by the lifting plate to contact the self-heating tray to realize charging. In this design, when not in use, the lifting plate, the charging part and the driving part are integrated below the line body, which does not affect the normal progress of other processes on the line body. At the same time, the space below the line body is reasonably utilized, and the integration degree is high without occupying extra space; at the same time, the driving part is convenient to drive, and the lifting plate and the charging part can be lifted at any time to supply power to the tray to ensure continuous operation.

[0013] As a further solution of the present invention: the driving part includes a sliding plate, several groups of pushing blocks are installed on the sliding plate, and a cylinder for driving the sliding plate to move horizontally is set on the bottom frame. When the cylinder pushes the sliding plate to move, it can drive the pushing blocks to squeeze the lifting plate to lift.

[0014] In this application, a cylinder is used to push a sliding plate, which in turn drives a pushing block to move. While the pushing block is moving, it squeezes and lifts a lifting plate upwards, thereby lifting it. This lifting method is relatively gentle compared to directly using a cylinder or hydraulic lifting, providing a certain degree of protection for the subsequent connection of the charging male head and the charging female head, enabling the subsequent flexible contact between the charging male head and the charging female head.

[0015] As a further solution of the present invention: The pushing block has a triangular structure, and the surface in contact with the lifting plate is an inclined surface.

[0016] In this application, the pushing block is set to have a triangular structure, and the surface in contact with the upper part of the lifting plate is an inclined surface. Therefore, when the triangular pushing block moves forward or backward, it can push the lifting plate in contact with its inclined surface to move up or down. This lifting method is suitable for the connection of charging plugs, with a gentle insertion that will not damage the charging plugs.

[0017] As a further solution of the present invention: A sliding table parallel to the sliding plate is provided on the bottom frame and below the sliding plate, and a slider capable of sliding on the sliding table is provided at the lower part of the sliding plate.

[0018] In this application, a sliding table is provided below the sliding plate, and the sliding table is parallel to the sliding plate. When the cylinder pushes the sliding plate, it can move along the direction of the sliding table to ensure the stability of the sliding table movement, and further ensure that the pushing block can accurately push the roller below the lifting plate, improving the lifting accuracy.

[0019] As a further solution of the present invention: The lifting plate includes a lifting plate. The bottom of the lifting plate is installed on the bottom frame through a telescopic rod, and a positioning column cooperating with the self-heating tray is installed at the top of the lifting plate; rollers cooperating with the driving member are provided at the bottom of the lifting plate.

[0020] In this application, telescopic rods are provided at the four corner positions at the bottom of the lifting plate and are connected to the bottom frame through the telescopic rods. The lifting direction of the lifting plate is along the telescopic direction of the telescopic rods. The setting of the telescopic rods can ensure the accurate lifting of the lifting plate in height.

[0021] As a further solution of the present invention: A tray positioning block cooperating with the lifting and positioning charging mechanism is installed at the bottom of the self-heating tray, and a charging female head cooperating with the charging male head in the charging member is also installed at the bottom of the self-heating tray.

[0022] In this application, a tray positioning block is provided at the bottom of the self-heating tray. The tray positioning block is used for positioning with the lifting and positioning charging mechanism to ensure the precise cooperation between the lifting and positioning charging mechanism and the tray positioning block, and further achieve the precise connection of the charging male head and the charging female head.

[0023] As a further solution of the present invention: the heating and pressing mechanism includes a positioning plate installed on the self-heating tray, a slide rail is installed on the positioning plate, a moving bracket is slidably connected to the slide rail, a pressing seat and a thermocouple are sequentially installed on the moving bracket in the direction towards the battery module, and a temperature control member is further provided on the moving bracket; an elbow clamp for driving the moving bracket to move towards the battery module is further provided on the positioning plate; a spring-back assembly is arranged on one side of the positioning plate and located on the moving bracket.

[0024] The tray of this application is equipped with a side plate pressing mechanism, which does not require tooling installation and disassembly, and the mechanism does not need to be equipped with a return wire; the manual elbow clamp is convenient to use and has a low investment; the elbow clamp has a dead point self-locking in the working posture and can automatically maintain the working posture; this application adopts a paste heating mode, and the heat transfer speed of direct heating is fast.

[0025] As a further solution of the present invention: the spring-back assembly includes a movable block installed on the moving bracket and a fixed block installed on the positioning plate. The movable block and the positioning plate are connected by a stud, and a second spring is sleeved outside the stud located between the movable block and the positioning plate.

[0026] The pressing mechanism of this application is equipped with a spring-back assembly with a fixed position, which can reduce the risk of spring-back operation; it has a simple structure, low equipment configuration, low cost, convenient maintenance, and wide applicability.

[0027] As a further solution of the present invention: the charging member adopts a flexible joint mechanism, which includes a movable mounting plate and a lower mounting plate. The movable mounting plate is slidably connected to the lower mounting plate through a rod, and a first spring is sleeved outside the rod. A charging male head is installed on the top of the movable mounting plate.

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0048] Embodiment 1

[0049] Referring to Figure 1 and Figure 2 , a self-heating glue curing follow-up device for a battery module includes a self-heating tray 1, a lifting positioning charging mechanism 2, a workpiece 3, a heating and pressing mechanism 4, and a line body 5. The self-heating tray 1 is installed on the line body 5, and the line body 5 is an assembly line for battery module processing. The self-heating tray 1 can move to the corresponding process following the drive of the line body 5. During this process, the workpiece 3 is placed on the self-heating tray 1, and the workpiece 3 can be heated to achieve glue curing while the line body 5 drives it to move; several groups of lifting positioning charging mechanisms 2 can be set and installed at intervals under the line body 5. When the self-heating tray 1 moves directly above the lifting positioning charging mechanism 2, it can be charged through the lifting positioning charging mechanism 2; and the heating and pressing mechanism 4 is installed on the self-heating tray 1 to realize the heating and fixing of the battery module.

[0050] Referring to Figure 3 and Figure 4 , a bottom plate 12, a workpiece end pressing member 11, and a heating and pressing mechanism 4 are installed on the self-heating tray 1. The workpiece end pressing members 11 are installed on the left and right sides of the top of the bottom plate 12 respectively, and the heating and pressing mechanisms 4 are installed on the front and back sides of the top of the bottom plate 12 respectively; it should be noted that here, the front, back, left, and right are based on Figure 3 as a reference; the workpiece 3 (i.e., the battery module) is installed on the bottom plate 12. The two workpiece end pressing members 11 can press and position the workpiece 3 from the left and right directions, and the two heating and pressing mechanisms 4 can heat and fix the workpiece 3 from the front and back directions and realize glue curing.

[0051] Furthermore, a plurality of tray positioning blocks 13 are installed at the bottom of the self-heating tray 1. The tray positioning blocks 13 are used to engage with the positioning posts 22 on the lifting positioning charging mechanism 2 to play a role in limiting (referring to Figure 4 and Figure 10) Note that the tray positioning block 13 corresponds to the positioning post 22 in position. When the self-heating tray 1 moves to directly above the lifting and positioning charging mechanism 2, the tray positioning block 13 and the positioning post 22 can cooperate, and the number of the tray positioning block 13 and the positioning post 22 is the same. The specific number is determined according to the actual situation and is not limited in this application. A battery 15 and a charging female head 14 are arranged at the bottom of the self-heating tray 1 and on one side of a plurality of tray positioning blocks 13. The charging female head 14 is connected to the battery 15, and the charging female head 14 can be connected to the charging male head 261 on the lifting and positioning charging mechanism 2 to charge the battery 15.

[0052] Refer to Figure 10 and Figure 11 , the lifting and positioning charging mechanism 2 includes a bottom frame 27. An installation plate 28 is arranged at the top of the bottom frame 27. Two groups of lifting plates 21 are installed at the top of the installation plate 28. The two groups of lifting plates 21 have the same structure. Four corner positions at the bottom of the lifting plate 21 are detachably connected with telescopic rods through bolts or pins, and the bottom of the telescopic rods is detachably connected to the installation plate 28 through bolts or pins. Therefore, the lifting of the lifting plate 21 is carried out in the vertical direction along the telescopic rods. Four corner positions at the top of the two groups of lifting plates 21 are all installed with positioning posts 22, and the positioning posts 22 are used to engage with the tray positioning blocks 13 to achieve positioning. A flexible joint mechanism 26 is also arranged on the two groups of lifting plates 21 to charge the battery 15.

[0053] Further, refer to Figure 12 , the flexible joint mechanism 26 includes a charging male head 261, a movable installation plate 262, a rod 263, a first spring 264, a retaining piece 265 and a lower installation plate. The movable installation plate 262 is located directly above the lower installation plate, and both sides of the movable installation plate 262 are movably connected with the rod 263. The bottom of the rod 263 is connected to the lower installation plate through the retaining piece 265. A first spring 264 is sleeved on the outer side of the rod 263. A charging male head 261 is arranged at the middle position at the top of the movable installation plate 262, and the charging male head 261 can be connected to the charging female head 14 to charge the battery 15.

[0054] Refer to Figure 10 and Figure 11, a sliding plate 29 is provided at the top of the mounting plate 28 and below two sets of lifting plates 21. A cylinder 23 capable of driving the sliding plate 29 to move is installed on the bottom frame 27. The cylinder 23 can push the sliding plate 29 to move horizontally. A sliding table 210 is installed at the bottom of the sliding plate 29 and on the top of the bottom frame 27. A slider 211 slidably connected to the sliding table 210 is provided at the bottom of the sliding plate 29. When the cylinder 23 pushes the sliding plate 29 to move, the slider 211 can be driven to slide along the sliding table 210. It should be noted that in this application, a groove for the sliding plate 29 is reserved on the mounting plate 28, and the slider 211 passes through the groove and is slidably connected to the sliding plate 29. At the same time, a groove for installing the cylinder 23 is also reserved on the mounting plate 28.

[0055] Referring to Figure 10 and Figure 11 , four sets of pushing blocks 24 are provided at the top of the sliding plate 29 directly below each lifting plate 21; rollers 25 cooperating with the four pushing blocks 24 are provided at the bottom of each lifting plate 21. The pushing block 24 has a triangular structure, and the surface contacting the roller 25 is an inclined surface. Therefore, when the triangular pushing block 24 moves forward or backward under the drive of the sliding plate 29, the roller 25 contacting the inclined surface of the pushing block 24 can be pushed to move up or down. This lifting method is suitable for the connection of the charging plug, and the plugging is gentle and will not cause damage to the charging plug; during this process, since the moving direction of the sliding plate 29 is restricted by the sliding table 210, it can be ensured that the pushing block 24 can accurately contact the roller 25 when moving forward or backward, thereby ensuring the lifting or lowering of the lifting plate 21; it should be noted that the height of the inclined surface of the pushing block 24 is the same as the height of the lifting of the lifting plate 21. In actual operation, the height of the pushing block 24 can be designed according to the required lifting height of the lifting plate 21.

[0056] Referring to Figure 5 , during use, the workpiece 3 is installed on the bottom plate 12, and the workpiece 3 is positioned by two sets of workpiece end pressing members 11 and two sets of heating and pressing mechanisms 4; the workpiece 3 includes a stacked battery cell 31 composed of a plurality of battery cells. The number of battery cells is not limited in this application. Side plates 32 are installed on both sides of the stacked battery cell 31 through glue 33. The two sets of heating and pressing mechanisms 4 are in direct contact with the side plates 32 and are used to cure the glue 33 at the side plates 32.

[0057] Referring to Figure 6 , Figure 7 , Figure 8 and Figure 9, The two groups of heating and pressing mechanisms 4 are symmetrically arranged and have the same structure. The heating and pressing mechanism 4 includes a positioning plate 410 installed on the self-heating tray 1. On both sides of the top of the positioning plate 410, slide rails 48 are installed. A slider is slidably connected to the slide rails 48. Above the two groups of sliders, a moving bracket 43 is installed. In the direction of the workpiece 3, a pressing seat 44 and a thermocouple 45 are successively installed on the moving bracket 43. On the side of the thermocouple 45 facing the workpiece 3, a contact plate 46 is provided. A temperature sensor 47 is provided on the contact plate 46. At the same time, a temperature controller 42 is installed on the moving bracket 43.

[0058] Furthermore, an elbow clamp 41 is also provided on the positioning plate 410 and between the two groups of slide rails 48. When the elbow clamp 41 is in the working posture, it can be self-locked at the dead point to realize the automatic maintenance of the working posture.

[0059] Even further, referring to Figure 7 and Figure 9 , on one side of the moving bracket 43, a rebound assembly 49 is also installed. The rebound assembly 49 includes a movable block 491, a second spring 492, a fixed block 493 and a stud 494. The movable block 491 is fixed on the moving bracket 43, and the fixed block 493 is fixed on the positioning plate 410. There is a certain gap between the movable block 491 and the fixed block 493, and the two are connected by the stud 494. One end of the stud 494 is fixed to the movable block 491, and the other end slides through the fixed block 493. And a second spring 492 is sleeved on the outer side of the stud 494 between the movable block 491 and the fixed block 493.

[0060] The specific operation principle of this application is as follows:

[0061] During use, the workpiece 3 is installed and fixed on the self-heating tray 1, and is pressed and heated by the heating and pressing mechanism 4. The self-heating tray 1 operates at each station along the line body 5. Each station is equipped with a lifting and positioning charging mechanism 2, and the battery 15 of the self-heating tray 1 can be charged simultaneously during operation.

[0062] The workpiece 3 on the self-heating tray 1 is placed on the bottom plate 12. The workpiece end pressing member 11 presses both ends of the workpiece 3, and the heating and pressing mechanism 4 presses and heats both sides of the workpiece 3.

[0063] When operating the processes above and below the line body 5, the tray positioning block 13 is lifted and positioned by the positioning post 22 on the lifting and positioning charging mechanism 2. After the charging female head 14 and the charging male head 261 on the flexible joint mechanism 26 are docked, the battery 15 is charged.

[0064] The heating and pressing mechanism 4 is used to press the side plate 32 on the workpiece 3 and heat the glue 33 to quickly solidify. The elbow clamp 41 is manually pressed, and the movable bracket 43 carries the pressing seat 44, the thermocouple sheet 45, and the contact plate 46 to press the side plate 32. The thermocouple sheet 45 is used for heating. The temperature sensor 47 is used to detect the temperature uniformity of six positions on the contact plate 46. The temperature controller 42 is used to heat the feedback temperature and control the upper and lower limits of the temperature.

[0065] The contact plate 46 and the side plate 32 are in direct contact and pressed, and the temperature sensor 47 provides feedback of the temperature; the elbow clamp 41 has a dead point limiter. When the elbow clamp 41 is not in place, the spring 492 on the stud 494 between the movable block 491 and the fixed block 493 will rebound the movable bracket 43 out of the contact position;

[0066] When the lifting and positioning charging mechanism 2 is used for station operation, the cylinder 23 pushes the push block 24 to move linearly, and the roller 25 pushes the lifting plate 21 upward along the slope of the push block 24, and the positioning column 22 contacts the tray positioning block 13 to realize the positioning of the self-heating tray 1. The flexible joint mechanism 26 contacts the charging female connector 14 to charge the battery 15; the movable mounting plate 262 makes the charging male connector 261 flexibly contact the charging female connector 14 to charge the battery 15 through the spring 264 on the rod 263;

[0067] The workpiece 3 is mounted on the self-heating tray 1 , and the space between the stacked battery cells 31 and the side panels 32 is filled with glue 33 . The side panels 32 need to be pressed and heated to facilitate rapid solidification of the glue 33 .

[0068] The self-heating tray 1 of the present invention is provided with a heating and pressing mechanism 4, and the pressing by the elbow clamp 41 is convenient, and the heating and pressing mechanism 4 does not need to be disassembled; the heating and pressing mechanism 4 and the self-heating tray 1 flow together and do not need to be refluxed;

[0069] The self-heating tray 1 of the present application utilizes the existing assembly line 5 for operation, has its own heating function, and flows along with the assembly line operation, without the need for a specially configured heating room; the present application adopts a direct heating mode of application, and the heating speed is fast.

[0070] Example 2

[0071] The rest is the same as in the first embodiment, but the difference is that the second embodiment can replace the toggle clamp 41 with an automatic workpiece extrusion device, such as an air pump or a hydraulic rod, to achieve automatic extrusion.

[0072] Example 3

[0073] The rest is the same as in Example 1, but different therefrom in that the self-heating tray 1 in Example 3 may be selected to be without a battery, and when the self-heating tray 1 is moved to be directly above the lifting and positioning charging mechanism 2, it can be powered on for heating.

[0074] Example 4

[0075] Other aspects are the same as those of Embodiment 1. The difference is that in Embodiment 4, the thermocouple sheet 45 is replaced with other types of heating devices such as silicone rubber plates for heating.

[0076] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
