Description

Technical Field

[0001] The utility model relates to the technical field of machinery, and more specifically to a lifting device for gluing a battery pack. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] With the continuous development of the new energy industry, higher requirements are also put forward for the production process of battery packs. Among them, glue coating is an important step in the current battery production and manufacturing process, and the accuracy of glue coating is crucial to the performance of the battery pack.

[0004] Since the current manual gluing is extremely inefficient, wastes a lot of manpower, and it is difficult to ensure the uniformity of the glue and the thickness of the colloid, most people use semi-automatic or fully automatic gluing methods. For some large and heavy battery packs, they are generally transported by a trolley. After arriving at the gluing station, some are directly glued on the trolley, and some are transported to the positioning fixture for gluing. The method of transporting the battery pack to the fixture for gluing is inconvenient and consumes manpower, affecting working hours. The direct gluing method is easy to affect the gluing accuracy due to the unevenness of the trolley's rollers or the ground. Both methods have disadvantages.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the utility model and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the utility model. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide a lifting device for gluing a battery pack, which effectively improves the gluing accuracy.

[0007] In order to solve the above-mentioned technical problems, the utility model provides a lifting device for battery pack gluing, which is arranged at the gluing station and is used to lift a material cart loaded with battery packs, wherein the material cart includes a platform for placing the battery packs and a frame for installing and / or supporting the platform, and the lifting device includes a limiting channel for limiting the left and right sides of the frame of the material cart and at least two lifting members, wherein the lifting member includes a push plate that is driven to rise and fall, and the push plate is used to abut against the lower surface of the platform to lift the material cart.

[0008] Preferably, it further comprises a support frame which is arranged symmetrically on both sides, on which two groups of blocking cylinders are mounted, wherein one group of blocking cylinders cooperates to limit the forward movement of the material cart, and the other group of blocking cylinders cooperates to limit the backward movement of the material cart.

[0009] Preferably, the limiting channel includes an upper channel and a lower channel, a first limiting component is installed on the inner side of the lower end of the support frame, and a second limiting component is installed on the inner side of the upper end of the support frame, each first limiting component includes a first elongated mounting plate, a plurality of guide rollers are arranged on the first elongated mounting plate, the two first elongated mounting plates and their guide rollers together form a lower channel for limiting the skeleton on the lower side of the material cart, and the second limiting component includes a second elongated mounting plate, a plurality of guide rollers are arranged on the second elongated mounting plate, the two second elongated mounting plates and their guide rollers together form an upper channel for limiting the skeleton on the upper side of the material cart.

[0010] Preferably, the limiting channel comprises a feed end and a discharge end, the upper channel and the lower channel both have trumpet-shaped openings at the feed end, and the upper channel is shorter than the lower channel.

[0011] Preferably, the lifting member is a lifting cylinder installed on a support frame, and the lifting members include four, which are arranged in one-to-one correspondence with the four corners of the platform.

[0012] Preferably, positioning columns are provided on the push plates of at least one pair of diagonally arranged lifting members, and positioning holes matched with the positioning columns are provided on the platform.

[0015] By means of the above technical solution, the beneficial effects of the utility model are as follows:

[0016] The utility model of the lifting device for gluing the battery pack effectively solves the heavy and inefficient problems of manual transportation to the gluing station by lifting the material cart, significantly reduces the investment in labor costs, and improves the automation of the operation process. By lifting the material cart, the flatness requirement at the roller that originally required strict control is converted into a guarantee of the flatness of the lifting platform. In view of the fact that the platform design already meets the high-precision flatness standard, this conversion strategy can significantly improve the positioning accuracy and stability during the gluing operation, thereby optimizing the gluing quality and achieving higher process accuracy requirements. The setting of the blocking cylinder not only significantly enhances the limiting stability of the material cart, but also ensures that the material cart can achieve initial positioning with the help of the blocking cylinders set in front and behind after entering the limiting channel. This link plays a vital role in the smooth progress of the subsequent lifting work. BRIEF DESCRIPTION OF THE DRAWINGS

The lifting member 3 includes a push plate 301 that is driven to rise and fall. The push plate 301 is used to abut against the lower surface of the platform 101 to lift the material cart 1. Because the platform 101 itself is flat, as long as the platform 101 is lifted, the platform 101 is used as a support surface to control the flatness of the platform 101.

[0027] In order to achieve complete positioning of the material cart 1, two groups of blocking cylinders 5 are preferably installed on the support frame 4, one group of blocking cylinders 5 cooperates to limit the forward movement of the material cart 1, and the other group of blocking cylinders 5 cooperates to limit the backward movement of the material cart 1. Specifically, when the material cart 1 is pushed over, the group of blocking cylinders 5 located at the rear extends out until it abuts against the side wall of the material cart 1. After abutting, the sensor of the blocking cylinder 5 located at the rear sends a signal, and the control unit controls the group of blocking cylinders 5 located at the front to be pushed out, so that the blocking cylinders 5 in the front and rear directions jointly limit the forward and backward movement of the material cart 1.

[0028] Specifically, in order to limit the material cart 1 at the upper and lower sides at the same time to prevent deflection, the limiting channel 2 preferably includes an upper channel 6 and a lower channel 7, and a first limiting component is installed on the inner side of the lower end of the support frame 4, and a second limiting component is installed on the inner side of the upper end of the support frame 4. Each first limiting component includes a first elongated mounting plate 701, and a plurality of guide rollers 602 are arranged on the first elongated mounting plate 701. The two first elongated mounting plates 701 and their guide rollers 602 jointly form a lower channel 7 for limiting the skeleton 102 on the lower side of the material cart 1. The second limiting component includes a second elongated mounting plate 601, and a plurality of guide rollers 602 are arranged on the second elongated mounting plate 601. The two second elongated mounting plates 601 and their guide rollers 602 jointly form an upper channel 6 for limiting the skeleton 102 on the upper side of the material cart 1.

[0029] In order to prevent the material cart 1 from getting stuck at the entrance, the present application preferably configures the limiting channel 2 to include a feed end and a discharge end, and the upper channel 6 and the lower channel 7 both have trumpet-shaped openings at the feed end, and the upper channel 6 is shorter than the lower channel 7, and the upper channel 6 is only provided at the feed end.

[0030] Specifically, the lifting member 3 of the present application is a lifting cylinder installed on a support frame 4. The lifting member 3 includes four lifting members 3, which are arranged one by one corresponding to the four corners of the platform 101. A positioning column 8 is provided on the push plate 301 of at least one pair of diagonally arranged lifting members 3, and a positioning hole 9 adapted to the positioning column 8 is provided on the platform 101.

[0031] In order to monitor the material vehicle 1 entering and exiting the limiting channel 2 , a barcode scanning gun 10 for detecting the material vehicle 1 is preferably installed on one of the support frames 4 .

[0032] The above-described embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in the technical field on the basis of the present utility model are all within the protection scope of the present utility model.
