Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to an adjustable positioning device for aligning the spare size of a battery and a heat shrink film. Background Technique

[0002] In the battery production process, a heat shrink film sleeve is put on the battery, and through heating, the heat shrink film tightly wraps the battery surface to form a protective film on the battery surface. Affected by the shrinkage rate of the heat shrink film, in order to ensure the wrapping effect of the heat shrink film, when the heat shrink film is put on the battery, the length of the heat shrink film should exceed the length of the battery. The extra part of the heat shrink film relative to the battery is the spare part. For batteries of different sizes and heat shrink films with different shrinkage rates, the sizes of the spare parts of the heat shrink film required are different.

[0003] At present, in the process of aligning the battery and the heat shrink film, usually, the operator determines the spare size distance from the heat shrink film to the battery through multiple attempts. Basically, it is judged whether the spare size is qualified through experience. Judging whether the spare size is qualified by the subjective consciousness of people will have certain errors, which will lead to problems such as poor appearance of the final product and low consistency. At the same time, the alignment speed by the subjective judgment of the operator is slow, which affects the alignment efficiency of the battery and the heat shrink film.

[0004] Therefore, it is necessary to design a device that can adapt to different sizes of batteries and can quickly align the spare sizes of the battery and the heat shrink film in the heat shrink film covering process to solve the problems of low consistency and efficiency of the current heat shrink film products.

[0029] The detailed implementation manners of the present utility model will be introduced with reference to the accompanying drawings.

[0030] Refer to Figure 1 , in the figure is a three-dimensional schematic diagram of the adjustable positioning device for aligning the spare size 103 of the battery 101 and the heat shrink film 102. The device is sequentially provided with a positioning rod 1, a positioning plate 2, a locking member 4 and a bottom plate 5 from top to bottom. The positioning rod 1 and the positioning plate 2 are respectively positioned with the battery 101 and the heat shrink film 102. The heat shrink film 102 is sleeved on the battery 101 and moves up and down along the battery 101 and the positioning rod 1, so as to align the spare size 103 of the battery 101 and the heat shrink film 102.

[0031] Refer to Figures 1 to 5, An adjustable positioning device for aligning the spare dimension 103 between the battery 101 and the heat shrink film 102, comprising a positioning rod 1 and a positioning plate 2. The positioning rod 1 vertically penetrates through the sliding hole 22 of the positioning plate 2. A locking member 4 cooperating with the positioning rod 1 is provided at the lower part of the positioning plate 2. The upper side end face of the positioning rod 1 is set as a first positioning surface 11 in contact with the end face of the battery 101, and the upper side plane of the positioning plate 2 is set as a second positioning surface 21 in contact with the end face of the heat shrink film 102. The height difference 3 between the first positioning surface 11 and the second positioning surface 21 is the spare dimension 103 of the heat shrink film 102 sleeve. In the adjustment state, the positioning rod 1 moves along the sliding hole 22 to adjust the height difference 3 between the first positioning surface 11 and the second positioning surface 21, and after the adjustment is completed, the positioning rod 1 and the positioning plate 2 are fixed by the locking member 4.

[0032] The adjustable positioning device for aligning the spare dimension 103 between the battery 101 and the heat shrink film 102 in the embodiment of the present application has a simple structure, is easy to install and maintain, and has strong alignment accuracy and stability. It can meet the assembly requirements of various different specifications of batteries 101 and heat shrink films 102, and quickly align the spare dimension 103 between the battery 101 and the heat shrink film 102; the distance between the first positioning surface 11 and the second positioning surface 21 is adjusted by the up and down movement of the positioning rod 1, so as to adapt to the sizes of different batteries 101 and heat shrink films 102, and after the alignment is completed, the positioning rod 1 and the positioning plate 2 are fixed by the locking member 4 to ensure the alignment accuracy and stability.

[0033] It should be further noted that referring to Figure 2 , there are spare dimensions 103 at both ends of the battery 101 for the heat shrink film 102. The two spare dimensions 103 can be the same or different. Whether the two spare dimensions 103 are the same or not, both of these two spare dimensions 103 should meet the heat shrinkage requirements of the heat shrink film 102.

[0034] In order to stably connect the positioning rod 1 and the positioning plate 2, in this embodiment, referring to Figure 1 , a sliding sleeve 23 is provided along the sliding hole 22 on the lower side of the positioning plate 2. The locking member 4 is vertically arranged on the sliding sleeve 23. The locking member 4 includes a handle 41 and a screw rod 42. The screw rod 42 is threadedly connected to the sliding sleeve 23. One end of the screw rod 42 is fixed to the handle 41, and the other end is in contact with the outer side wall of the positioning rod 1 inside the sliding sleeve 23.

[0035] It can be understood that with such a setting, since the positioning rod 1 is a round rod, the positioning rod 1 can move up and down along the sliding hole 22 and the sliding sleeve 23 to adjust the height difference 3 between the first positioning surface 11 and the second positioning surface 21. After the adjustment is completed, the locking member 4 rotates the screw rod 42 through the handle 41, and the end face of the screw rod 42 will press against the positioning rod 1, so that the locking member 4 fixes the positioning rod 1 and the sliding sleeve 23.

[0036] In order to facilitate the adjustment of the height of the positioning rod 1 above the positioning plate 2, in this embodiment, referring to Figure 1 and Figure 3 , scale marks 12 indicating the height difference 3 between the first positioning surface 11 and the second positioning surface 21 are arranged at equal intervals along the axial direction on the outer side wall of the positioning rod 1, and the scale marks 12 start from the first positioning surface 11 of the positioning rod 1.

[0037] It can be understood that with such a setting, the scale marks 12 are used to indicate the height difference 3 between the first positioning surface 11 and the second positioning surface 21. The first positioning surface 11 serves as the starting point of the 0 scale mark 12, and each scale mark 12 represents 5 mm. Among them, the long scale marks 12 are marked with numbers, and several long scale marks 12 represent 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, and 70 mm respectively. By checking which scale mark 12 the second positioning surface 21 is located at, one can know what the height difference 3 between the first positioning surface 11 and the second positioning surface 21 is, and thus can accurately adjust the height difference 3 between the positioning rod 1 and the positioning plate 2 according to the remaining dimension 103 after the battery 101 and the heat shrink film 102 are aligned.

[0038] In order to ensure that the end face of the heat shrink film 102 can contact the second positioning surface 21, in this embodiment, referring to Figure 3 , the diameter of the positioning rod 1 is smaller than the diameter of the battery 101.

[0039] It can be understood that with such a setting, during the alignment process, the heat shrink film 102 is first put on the battery 101, and the battery 101 and the heat shrink film 102 are placed together on the positioning rod 1. The end face of the negative electrode of the battery 101 contacts the first positioning surface 11 of the positioning rod 1. Manually push the heat shrink film 102 downward. Since the diameter of the positioning rod 1 is smaller than the diameter of the battery 101, the end face of the heat shrink film 102 can contact the second positioning surface 21 downward.

[0040] In order to protect the battery 101, in this embodiment, referring to Figure 3 , a protective pad 14 is provided on the first positioning surface 11.

[0041] It can be understood that with such a setting, during the alignment process, the battery 101 is buffered by the protective pad 14, so that the battery 101 does not directly contact the positioning rod 1, avoiding the battery 101 from being knocked and damaged, thereby protecting the battery 101.

[0042] In order to avoid the first positioning surface 11 interfering with the positioning process of the battery 101 and the heat shrink film 102, in this embodiment, referring to Figure 1 and Figure 3 , the positioning rod 1 is provided with a round chamfer 13 at the edge of the first positioning surface 11.

[0043] It can be understood that with such a setting, the rounded chamfer 13 has two functions. The first function is to make the edge of the first positioning surface 11 transition smoothly, avoiding the edge of the first positioning surface 11 being too sharp. The second function is to guide the heat shrink film 102 to be pushed downward, preventing the first positioning surface 11 from blocking the downward movement of the heat shrink film 102 and achieving quick alignment.

[0044] In order to adapt to batteries 101 of more size models, in another embodiment, referring to Figure 4 and Figure 5 , a positioning sleeve 6 is sleeved on the upper end of the positioning rod 1, and the diameter of the positioning sleeve 6 is smaller than the diameter of the battery 101.

[0045] It can be understood that with such a setting, in order to adapt to batteries 101 with different diameters, multiple positioning sleeves 6 with different diameters can be set. For a battery 101 whose diameter is much larger than the diameter of the positioning rod 1, a corresponding-sized positioning sleeve 6 can be sleeved on the positioning rod 1. The size of the positioning sleeve 6 should be slightly smaller than the diameter of the battery 101. A groove 61 for clamping with the upper end of the positioning rod 1 is provided at the lower end of the positioning sleeve 6. When the positioning sleeve 6 is clamped on the positioning rod 1, the contact area between the positioning rod 1 and the battery 101 can be increased, enabling the positioning rod 1 to place a battery 101 of the corresponding size during the alignment process. Among them, when the positioning sleeve 6 is sleeved on the positioning rod 1, the end face of the positioning sleeve 6 is the first positioning surface 11. Due to the influence of the thickness of the positioning sleeve 6, the first positioning surface 11 is raised compared to the state without the positioning sleeve 6. In order to facilitate the adjustment of the height difference 3, the thicknesses of all the positioning sleeves 6 can be set to a fixed value, and it is set that the height of the first positioning surface 11 is correspondingly raised by 5 mm when the positioning sleeve 6 is sleeved.

[0046] In order to be stably placed on the workbench 7, in this embodiment, referring to Figure 4 , it further includes a bottom plate 5 connected to the external workbench 7. The bottom plate 5 is vertically fixed to the lower end of the positioning rod 1, and the area of the bottom plate 5 is larger than the area of the positioning plate 2.

[0047] It can be understood that with such a setting, the bottom plate 5 serves as a load-bearing plate to bear the weight of the entire device, enabling the entire device to be stably placed on the workbench 7. A bottom plate 5 with a larger area is used to ensure the stability of the entire device and prevent the entire device from tipping over.

[0048] In addition to the placement method through the bottom plate 5, in another embodiment, referring to Figure 5 , the positioning plate 2 is placed in the card slot 71 of the external workbench 7.

[0049] It can be understood that with such a setting, by connecting the positioning plate 2 to the workbench 7, the positioning rod 1 moves up and down relative to the positioning plate 2 to adjust the height difference 3 between the first positioning surface 11 and the second positioning surface 21. The positioning plate 2 is clamped in the card slot 71, enabling the positioning plate 2 and the workbench 7 to complete positioning.

[0050] The working process of the adjustable positioning device for the alignment of the spare dimension 103 between the alignment battery 101 and the heat shrink film 102 in the embodiment of the present application is as follows: First, confirm the spare dimension 103 between the battery 101 and the heat shrink film 102 according to the dimensions of the battery 101, the dimensions of the heat shrink film 102 and the heat shrinkage rate. Adjust the positions of the positioning rod 1 and the positioning plate 2 according to the spare dimension 103. Turn the handle 41 to loosen the screw rod 42 from the positioning rod 1. The positioning rod 1 moves up and down along the sliding hole 22 and the sliding sleeve 23 to the proper position, and adjust the height difference 3 between the first positioning surface 11 of the positioning rod 1 and the second positioning surface 21 of the positioning plate 2 to be the same as the spare dimension 103. Then, tighten the screw rod 42 through the handle 41. When in use, first put the heat shrink film 102 on the battery 101, place the battery 101 and the heat shrink film 102 together on the positioning rod 1. The negative end face of the battery 101 contacts and aligns with the first positioning surface 11 of the positioning rod 1. Push the heat shrink film 102 downward so that the end face of the heat shrink film 102 contacts the second positioning surface 21 of the positioning plate 2, thereby aligning the spare dimension 103 between the battery 101 and the heat shrink film 102. After the alignment is completed, pull out the heat shrink film 102 together with the battery 101 from the positioning rod 1.

[0051] The embodiment of the present application can be adjusted according to different sizes of the battery 101 and the heat shrink film 102, and can well adapt to the alignment operation of the spare dimensions 103 of different sizes of the battery 101 and the heat shrink film 102. The alignment is accurate, improving the production efficiency and the qualified product rate.

[0052] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
