Description

Technical Field

[0001] This utility model relates to a battery processing device, specifically a bending device. Background Technology

[0002] The casing of a dry cell battery is usually made of aluminum alloy, which is mainly used to protect the battery cell and electrochemical components inside the dry cell battery, and also has multiple functions such as conductivity, thermal conductivity and corrosion resistance.

[0003] In the process of manufacturing the aluminum casing for dry cell batteries, the top cover of the battery casing needs to be bent and then fixed to the opening of the battery casing. Currently, the bending of the top cover is usually done manually by machine. However, the manual bending process is obviously less efficient. During the bending process, since the manually operated machine completes the bending in one go, improper operation, such as bending too fast or too slow, or even a slight misalignment of the top cover, can damage the top cover, greatly increasing the probability of waste. Utility Model Content

[0004] The purpose of this utility model is to provide a bending device that, by setting up four sets of upper bending components and four sets of lower bending components in cooperation, performs four bends on the top cover of the battery aluminum shell, realizing fully mechanized bending processing, eliminating the trouble of manual operation, improving processing efficiency, and because fully mechanized processing can avoid improper manual operation, improve the yield rate and reduce the probability of material scrap.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending device, comprising a support frame and a bending frame disposed on one side of the support frame, wherein an upper bending assembly and a lower bending assembly are disposed on the bending frame, the upper bending assembly comprising an upper support arm and an upper attachment plate fixed to the upper support arm, an upper positioning plate being fixed to one end of the upper attachment plate near the upper support arm, a second cylinder being fixed to one end of the upper positioning plate away from the upper attachment plate, the output end of the second cylinder being connected to an upper moving rod, and an upper bending plate being fixed to the bottom of the upper moving rod. The lower bending assembly includes a lower support arm and a lower attachment plate fixed to the lower support arm. A third cylinder is fixed to the end of the lower attachment plate away from the lower support arm. The output end of the third cylinder is connected to a lower moving rod. A lower bending plate is fixed to the top of the lower moving rod. An upper bending plate is located above the lower bending plate, and the upper bending plate cooperates with the lower bending plate to bend the top cover of the battery. After bending, the top cover is pressed into the opening of the aluminum shell of the battery to seal the aluminum shell of the battery. The top cover of the battery is a cavity structure with an opening at one end and a hollow interior.

[0006] Preferably, a support assembly is provided on the support frame. The support assembly includes a mounting plate and a first cylinder fixed to the lower end face of the mounting plate. The mounting plate is fixed to one end of the support frame near the bending frame.

[0007] Preferably, the output end of the first cylinder is fixedly connected to a storage seat, the top of which is arc-shaped and positioned above the mounting plate.

[0008] Preferably, both the upper support arm and the lower support arm are fixed on the bending machine frame, and multiple upper support arms and multiple lower support arms are provided.

[0009] Preferably, both the second and third cylinders are inclined, with the second cylinder positioned above the third cylinder.

[0010] Preferably, the upper moving rod is slidably mounted on the upper positioning plate, and the lower moving rod is slidably mounted on the sliding sleeve, which is fixed to the upper end face of the lower positioning plate.

[0011] Preferably, a positioning groove is provided at one end of the lower bending plate near the upper bending plate, and the positioning groove is inclined.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the cooperation of four sets of upper bending components and four sets of lower bending components, performs four bending processes on the top cover of the battery aluminum shell, and finally bends the top cover into shape and presses it into the opening of the battery aluminum shell, thus completing the fully mechanized automatic processing of the battery aluminum shell, eliminating manual operation and improving processing efficiency.

[0014] 2. This utility model, because this device realizes the fully mechanized automatic processing of the battery aluminum shell top cover, effectively avoids the problems of improper bending rate and top cover position deviation caused by manual operation, reduces the probability of the top cover being damaged and scrapped during bending, and greatly improves the yield of battery aluminum shell top cover bending.

The mounting plate 31 is fixed to one end of the support frame 1 near the bending frame 2. The output end of the first cylinder 32 is fixedly connected to a placement seat 33. The top of the placement seat 33 is arc-shaped and is located above the mounting plate 31, so that the battery aluminum shell can be fixed on the placement seat 33.

The lower bending assembly 5 includes a lower support arm 51 and a lower attachment plate 52 fixed to the lower support arm 51.

[0028] Please see Figures 3 to 4 An upper positioning plate 43 is fixed to one end of the upper attachment plate 42 near the upper support arm 41. A second cylinder 44 is fixed to one end of the upper positioning plate 43 away from the upper attachment plate 42. The output end of the second cylinder 44 is connected to an upper moving rod 45. A third cylinder 53 is fixed to one end of the lower attachment plate 52 away from the lower support arm 51. The output end of the third cylinder 53 is connected to a lower moving rod 55. A lower bending plate 56 is fixed to the top of the lower moving rod 55. The upper bending plate 46 is located above the lower bending plate 56. The upper bending plate 46 and the lower bending plate 56 cooperate to bend the top cover of the battery and press the top cover into the opening of the battery aluminum shell after bending to seal the battery aluminum shell. The top cover of the battery is a cavity structure with an opening at one end and a hollow interior.

[0029] Please see Figure 5 The bottom of the upper moving rod 45 is fixed with an upper bending plate 46, and the top cover of the battery aluminum shell is located below the upper bending plate 46. The top cover is bent into a V shape.

[0030] Please see Figure 6 The second cylinder 44 and the third cylinder 53 are both inclined, with the second cylinder 44 located above the third cylinder 53.

[0032] Please refer to the following: Figures 1 to 7 In the operation of this utility model, the first robotic arm places the aluminum battery casing on the seat 33 of the first set of support components 3. The second robotic arm moves the top cover of the aluminum battery casing to the opening of the aluminum battery casing, which is located between the first set of upper bending plates 46 and the first set of lower bending plates 56. The first set of second cylinders 44 is driven to move the upper moving rod 45 downward, causing the upper bending plate 46 to move downward and contact the top cover. At the same time, the first set of third cylinders 53 is driven to drive the lower moving rod 55 upward, causing the lower bending plate 56 to move to the bottom of the top cover, so that the top cover is placed on the bottom of the top cover. Within the positioning slot 561, the upper bending plate 46 and the lower bending plate 56 work together to bend the top cover once. Subsequently, the upper bending plate 46 and the lower bending plate 56 release the top cover from its fixation, and the first robotic arm delivers the battery aluminum shell to the next placement seat 33. The second robotic arm then delivers the top cover to the next set of upper bending components 4 and lower bending components 5 for a second bend. Through the cooperation of four sets of support components 3, four sets of upper bending components 4, and four sets of lower bending components 5, the top cover is bent four times, achieving fully mechanized automatic bending, which is beneficial to improving processing efficiency and yield. The structure of the robotic arm is existing technology and will not be described in detail here.
