Abstract
Description
Technical Field
[0001] This utility model relates to the field of power battery technology, and in particular to a power battery pack assembly tooling. Background Technology
[0002] An existing patent (publication number: CN218461300U) discloses a power battery pack assembly tooling. This utility model can fix the battery pack by setting a fixing component, a controller, a rotating component, and a driving component, and can automatically flip the battery pack during the welding of the positive and negative terminals and copper sheets, greatly reducing manual workload and improving work efficiency. However, in practical applications, the rotating component structure in the above-mentioned technical solution is complex, which is not conducive to later maintenance. Moreover, the utility model has limited uses and poor functionality in the assembly process, which is not conducive to battery pack assembly. Therefore, we propose a power battery pack assembly tooling. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a power battery pack assembly fixture.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] Design a power battery pack assembly fixture, including a base plate with support frames fixed at both ends. A turntable connected to a servo motor via a drive shaft is mounted on the support frame. A limiting groove 1 is detachably connected between the turntables. A limiting groove 2 is provided above the limiting groove 1 and docks with it. Both limiting groove 1 and limiting groove 2 have a through-hole. An electric push rod with its stroke end connected to the limiting groove 2 is mounted on the base plate. Both limiting groove 1 and limiting groove 2 have a detachable filling frame. A pushing mechanism is movably mounted above the limiting groove 2. The pushing mechanism includes a pressure plate docking with the processing port.
[0006] In the above scheme, the servo motor is disposed at the end of the base plate, and pulleys are installed on both the drive shaft and the output shaft of the servo motor, and a belt is connected between the pulleys.
[0007] In the above scheme, the servo motor is provided with a protective cover that is fixed to the base plate.
[0008] In the above scheme, a connecting component is provided between the turntable and the limiting groove. The connecting component includes a connecting shaft fixed to the limiting groove. A sleeve is movably provided on the connecting shaft. A locking cylinder is fixed on the turntable and sleeved on the sleeve. A locking block is fixed on the side wall of the sleeve. A locking groove matching the locking block is provided on the locking cylinder.
[0009] In the above scheme, a first claw is fixed on the filling frame, and a second claw that matches the first claw is fixed on the first limiting groove and the second limiting groove.
[0010] In the above scheme, the pushing mechanism also includes a column fixed on the base plate, a rotating plate connected to the top of the column via a rotating shaft, a cylinder installed at the end of the rotating plate away from the rotating shaft, and the stroke end of the cylinder connected to the pressure plate.
[0011] In the above scheme, the bottom of the pressure plate is covered with a buffer layer.
[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a support frame, drive shaft, pulley, and servo motor, the support frame provides sufficient support for the turntable. Compared with the prior art, the structure is simple and facilitates the maintenance of the transmission parts, mainly the pulley, by the staff, thus improving practicality. At the same time, it improves the stability of the turntable during rotation. The pulley transmission technology used in this application is quite mature and fully ensures stable operation. By setting up a limiting groove one, a filling frame, and a limiting groove two, the filling frame increases the friction between the upper and lower covers of the battery pack. The upper and lower covers of the battery pack are then placed in limiting groove two and limiting groove one, respectively. The battery module is filled into the lower cover. After that, by moving limiting groove two downward, the upper cover can be placed on the lower cover, thus initially completing the assembly of the battery pack. Compared with the prior art, it can effectively assemble the smallest battery unit and expand the scope of use. By setting up a pushing mechanism, after the battery module is filled, the pressure plate is moved downward by controlling the cylinder, thereby disengaging the upper cover located in the filling frame from limiting groove two and pressing it against the lower cover, thus promoting the completion of battery pack assembly.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0020] Please see Figure 1-4 This utility model provides a technical solution: a power battery pack assembly tooling, including a base plate 1 with support frames 21 fixed at both ends, a turntable 2 connected to a servo motor 7 via a drive shaft 3 on the support frame 21, and a limit groove 5 detachably connected between the turntables 2, with the limit groove 5 eccentrically connected to the turntable 2.
[0021] Furthermore, a connecting assembly 4 is provided between the turntable 2 and the limiting groove 5. The connecting assembly 4 includes a connecting shaft 41 fixed to the limiting groove 5, and a sleeve 42 movably mounted on the connecting shaft 41. The radius of the connecting shaft 41 near the sleeve 42 is larger than that of the other end. A locking cylinder 43 is fixed on the turntable 2 and sleeved on the sleeve 42. A locking block 44 is fixed to the side wall of the sleeve 42. The locking cylinder 43 is provided with a locking groove 45 that matches the locking block 44. Figure 3 As shown, the locking groove 45 is L-shaped. By moving the sleeve 42 and rotating the sleeve 42, the locking cylinder 43 and the sleeve 42 can be locked, which is convenient for disassembly and assembly.
[0022] Above the limiting groove 5, there is a limiting groove 9 that connects with it. Both the limiting groove 5 and the limiting groove 9 have a through-hole 14. The processing port 14 can be used to weld the positive and negative electrodes and copper sheets. An electric push rod 13 with its stroke end connected to the limiting groove 9 is vertically mounted on the substrate 1. The electric push rod 13 is located at the four corners of the limiting groove 9. Both the limiting groove 5 and the limiting groove 9 have a detachable filling frame 10. The filling frame 10 is made of EVA foam, which not only has a cushioning effect, but also uses the friction between it and the battery pack cover to limit the battery pack cover.
[0023] Furthermore, such as Figure 2As shown, a first claw 11 is fixed on the filling frame 10, and a second claw 12 that fits with the first claw 11 is fixed on the first limiting groove 5 and the second limiting groove 9. The first claw 13 is Z-shaped. The first claw 11 and the second claw 12 are used to facilitate disassembly and assembly.
[0024] Specifically, by setting a limiting groove 5, a filling frame 10, and a limiting groove 9, the filling frame 10 increases the friction with the upper and lower covers of the battery pack. Then, the upper and lower covers of the battery pack are placed in the limiting groove 9 and the limiting groove 5, respectively. The battery module is filled in the lower cover. After that, by moving the limiting groove 9 downward, the upper cover can be placed on the lower cover, thus initially completing the assembly of the battery pack. Compared with the existing technology, this method can effectively assemble the smallest battery unit and expand the scope of application.
[0025] Furthermore, the servo motor 7 is located at the end of the base plate 1, and pulleys 6 are mounted on both the drive shaft 3 and the output shaft of the servo motor 7. A belt is connected between the pulleys 6. Power is provided by the servo motor 7, and the drive shaft 3 is rotated under the action of the pulleys 6 and the belt, which in turn causes the turntable 2 to rotate.
[0026] Furthermore, the servo motor 7 is provided with a protective cover 8 that is fixed to the base plate 1; the protective cover 8 is used to protect the servo motor 7.
[0027] Specifically, by setting up a support frame 21, a drive shaft 3, a pulley 6, and a servo motor 7, the support frame 21 provides sufficient support for the turntable 2. Compared with the prior art, the structure is simple, which makes it easier for staff to maintain the transmission parts, mainly the pulley 6, in the later stages, thus improving practicality. At the same time, it improves the stability of the turntable 2 when rotating. The pulley 6 transmission technology used in this application is quite mature and fully ensures stable operation.
[0028] A pushing mechanism is provided above the limiting groove 2 9. The pushing mechanism includes a pressure plate 18 that is connected to the processing port 14.
[0029] Furthermore, the pushing mechanism also includes a column 15 fixed on the base plate 1. The top of the column 15 is connected to a rotating plate 17 via a rotating shaft 16. A cylinder 20 is vertically mounted on the end of the rotating plate 17 away from the rotating shaft 16. The stroke end of the cylinder 20 is connected downward to the pressure plate 18. By moving the pressure plate 18 downward, the upper cover located in the filling frame 10 is disengaged from the limiting groove 2 9.
[0030] Furthermore, the bottom of the pressure plate 18 is covered with a buffer layer 19, which is made of rubber. The buffer layer 19 is used to prevent the battery pack cover from being damaged by the pressure plate 19.
[0031] Specifically, by setting up a pushing mechanism, after the battery module is filled, the cylinder 20 is controlled to move the pressure plate 18 downward, thereby disengaging the upper cover located in the filling frame 10 from the limiting groove 2 9 and pressing it against the lower cover to promote the battery pack to complete assembly.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
