Description

Technical Field

[0001] This utility model relates to the field of battery protection board production technology, and in particular to an automatic bending machine for battery protection boards. Background Technology

[0002] The battery protection board is a crucial safety and management component in lithium battery packs. It is mainly used to prevent abnormal conditions such as overcharging, over-discharging, overcurrent, and short circuits, so as to ensure the safety performance of the battery, extend its service life, and improve the reliability of the system.

[0003] Because the battery protection board needs to be compatible with the battery pack, it needs to be bent and shaped at a certain angle. Currently, battery protection boards are generally bent manually. However, since workers cannot be consistent in the bending position and dimensions, the bent and shaped battery protection boards cannot match the battery pack, resulting in scrapped battery protection boards and increased costs. Furthermore, the workload of bending battery protection boards is large, and prolonged bending can easily lead to fatigue, which greatly reduces the bending efficiency and affects the bending accuracy. Therefore, a fully automatic bending machine needs to be designed. Utility Model Content

Many specific details are set forth in the following description to provide a full understanding of this utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Please see Figure 1 and Figure 2An automatic bending machine for battery protection boards includes a frame platform 100, a material receiving station 200, a loading robot 300, a circular conveyor line 400, a bending station 500, an unloading robot 600, and a fixture return mechanism 700, all mounted on the frame platform 100. The loading robot 300 is located between the material receiving station 200 and the circular conveyor line 400. The bending station 500 is located on the side of the circular conveyor line 400. The unloading robot 600 is located between the circular conveyor line 400 and the fixture return mechanism 700. A clamp 800 is mounted on the circular conveyor line 400, which can drive the clamp 800 to move. The side of line 400 is also provided with an opening mechanism 900 that cooperates with the clamp 800. There are two sets of opening mechanisms 900, one set is close to the loading robot 300 and the other set is close to the unloading robot 600. The material receiving station 200 is used to place plastic trays. The loading robot 300 is used to transport the products in the plastic trays to the clamp 800. The opening mechanism 900 is used to open the clamp 800 so that products can be placed in or taken out of the clamp 800. The bending station 500 is used to install the bending module for bending the products. The unloading robot 600 is used to transport the bent products to the fixture return mechanism 700 for collection.

[0036] Specifically, when bending and shaping the battery protection board, a worker or robot places a plastic tray containing the battery protection board to be bent into the receiving station 200. The loading robot 300 then transports the battery protection board from the plastic tray to the clamp 800 of the circular conveyor line 400. During placement, the clamping mechanism 900 near the loading robot 300 acts on the clamp 800 to open it, facilitating the placement of the battery protection board into the clamp 800. After the battery protection board is placed, the circular conveyor line 400 drives the clamp 800 to move to the bending station 500. The bending station 500 is used to install the bending module. This bending module is modularly designed and can be disassembled and reassembled according to different bending angles of the battery protection board. Alternatively, when the fixture 800 moves to the bending station 500, the corresponding bending module bends and shapes the battery protection board in the fixture 800. After the battery protection board is bent and shaped, the circular conveyor line 400 will drive the fixture 800 to move again and move the fixture 800 to another set of clamping mechanisms 900. The clamping mechanism 900 will open the fixture 800 again. At this time, the unloading robot 600 will take out the bent battery protection board from the fixture 800 and place the taken-out battery protection board into the fixture tray of the fixture return mechanism 700 for collection. This realizes the automatic bending of the battery protection board. Automatic bending and shaping can improve the bending efficiency of the battery protection board and ensure the bending consistency of the battery protection board, thereby ensuring the bending quality of the battery protection board.

[0037] The loading robot 300, the circular conveyor line 400, the bending module, and the unloading robot 600 in this embodiment are all existing technologies, so they will not be described in detail here.

[0038] Of course, to ensure the bending quality of the battery protection board and to ensure smooth operation of the automatic bending machine, this embodiment also includes a first detection mechanism 1000 and a second detection mechanism 2000. Two sets of the first detection mechanism 1000 and the second detection mechanism 2000 are provided, and both are CCD vision detection systems operating along the bending direction of the battery protection board. One set of the first detection mechanism 1000 is located behind the material receiving station 200. This first detection mechanism 1000 is used to detect whether the loading robot 300 has picked up the battery protection board to be bent. The first detection mechanism 1000 is located in front of the fixture return mechanism 700. This first detection mechanism 1000 is used to detect whether the unloading robot 700 has picked up the bent battery protection board, to ensure that there are still battery protection boards in the fixture 800 that have not been removed, thereby ensuring that the automatic bending machine can work smoothly. The two second detection mechanisms 2000 are located on both sides of the bending station 500. This second detection mechanism 2000 is for offset detection, used to detect whether the position of the battery protection board in the fixture 800 is offset (displacement), thereby ensuring the bending accuracy of the battery protection board and improving the bending quality of the battery protection board.

[0039] Please see Figures 3 to 8To facilitate the placement of the bent battery protection board into the fixture 800 and the removal of the bent battery protection board from the fixture 800, the fixture 800 in this embodiment includes a mounting plate 810, a main clamping plate 820, a fixed side plate 830, a movable side plate 840, and a movable end plate 850. The mounting plate 810 is connected to the circular conveyor line 400. The main clamping plate 820 is mounted on the mounting plate 810. The fixed side plate 830, movable side plate 840, and movable end plate 850 are respectively mounted on the main clamping plate 820, with the movable side plate 840 facing the fixed side plate 830. The movable end plate 850 is located at the ends of the fixed side plate 830 and the movable side plate 840. The end plates 850 are arranged together to form a placement space, and elastic members 860 are abutted against the back of both the movable side plate 840 and the movable end plate 850. Meanwhile, the clamping mechanism 900 includes a base 910, a lifting plate 920, a positioning unit 930, an X-axis drive unit 940, and a Y-axis drive unit 950. The base 910 is equipped with a lifting cylinder 960, and the lifting plate 920 is connected to the lifting cylinder 960. The positioning unit 930, the X-axis drive unit 940, and the Y-axis drive unit 950 are respectively installed on the lifting plate 920. The lifting cylinder 960 can drive the lifting plate 920 to move up and down, thereby driving the positioning unit 930, the X-axis drive unit 940, and the Y-axis drive unit 950 to move up and down and cooperate with the clamp 800.

[0040] When the loading robot 300 places the battery protection board to be bent onto the clamp 800, the lifting cylinder 960 on the base 910 drives the lifting plate 920 to rise. As the lifting plate 920 rises, it moves the positioning unit 930, the X-axis drive unit 940, and the Y-axis drive unit 950 upwards. After reaching the set position, the positioning unit 930 positions the main clamping plate 820 to ensure accurate positioning between the clamp 800 and the opening mechanism 900. Then, the X-axis drive unit 940 drives the movable side plate 840 and the movable end plate 850 to move outwards to open the placement space. As the movable side plate 840 and the movable end plate 850 move outwards, they compress the elastic element 860, which is a spring. At this time, the loading machine... The robotic arm 300 can easily place the battery protection board to be bent into the placement space of the clamp 800. After placement, the Y-axis drive unit 950 pushes and positions one end of the battery protection board in the placement space, while the X-axis drive unit 940 resets. The movable side plate 840 and movable end plate 850 are reset under the action of the elastic element 860, thereby positioning the other end and both sides of the battery protection board in the placement space. Finally, the fixed side plate 830, movable side plate 840, movable end plate 850, X-axis drive unit 940 and Y-axis drive unit 950 are used to position and clamp the battery protection board in the placement space, so as to facilitate subsequent bending and shaping of the battery protection board and ensure the precise positioning of the battery protection board, thereby ensuring the quality of battery bending and shaping.

[0041] In order to achieve the positioning of the main clamping plate 820, in this embodiment, a positioning hole 821 is provided in the main clamping plate 820, and a clearance hole 811 is provided in the mounting plate 810. The positioning unit 930 includes a positioning support plate 931 and a positioning post 932. The positioning support plate 931 is set on the lifting plate 920, and the positioning post 932 is set on the positioning support plate 931. The positioning post 932 corresponds to the positioning hole 821. When the lifting cylinder 960 drives the lifting plate 920 to rise, it will lift the positioning unit 930 along with it. The positioning post 932 on the positioning support plate 931 will pass through the clearance hole 811 of the mounting plate 810 and be inserted into the positioning hole 821 of the main clamping plate 820, thereby achieving the positioning of the main clamping plate 820. This ensures that the positions of the clamping mechanism 900 and the clamp 800 are accurate, and thus ensures the accurate placement of the battery protection board later.

[0042] Meanwhile, in order to drive the movable side plate 840 and the movable end plate 850 to move outward for easy placement of the battery protection board, a toggle groove 841 is provided at the bottom of the movable side plate 840, and a toggle part 851 is provided at the bottom of the movable end plate 850, with one side of the toggle part 851 being an inclined surface. The mounting plate 810 also has a first movable hole 812 and a second movable hole 813. The first movable hole 812 corresponds to the toggle groove 841, and the second movable hole 813 corresponds to the toggle groove 841. The two movable holes 813 correspond to the actuating part 851; the X-axis drive unit 940 includes an X-axis drive cylinder 941, an X-axis moving plate 942, an actuating column 943 and an actuating ring 944. The X-axis drive cylinder 941 is mounted on the lifting plate 920. The X-axis moving plate 942 is connected to the X-axis drive cylinder 941. The actuating column 943 and the actuating ring 944 are mounted on the X-axis moving plate 942 and cooperate with the actuating groove 841 and the actuating part 851 respectively.

[0043] When the battery protection board to be bent needs to be placed in the placement space of the clamp 800, the lifting cylinder 960 drives the lifting plate 920 to rise upwards. After rising to the set position, the actuating pin 943 in the X-axis drive unit 940 passes through the first movable hole 812 and is placed in the actuating groove 841, while the actuating ring 944 passes through the second movable hole 813 and cooperates with the actuating part 851. Then, the X-axis drive cylinder 941 drives the X-axis moving plate 942 to move, and the X-axis moves... When the movable plate 942 moves, it moves the actuating column 943 and the actuating ring 944. The actuating column 943 acts on the actuating groove 841 of the movable side plate 840, pushing the movable side plate 840 outwards. Simultaneously, the actuating ring 944 acts on the inclined surface of the actuating part 851 of the movable end plate 850, squeezing the movable end plate 850 outwards, thus opening the placement space and facilitating the loading robot 300 to place the battery protection board in the placement space. Similarly, after the battery protection board on the fixture 800 is bent, the X-axis drive unit 940 also pushes the movable side plate 840 and the movable end plate 850 outwards to open the placement space, thus facilitating the unloading robot 600 to remove the battery protection board from the placement space of the fixture 800.

[0044] In this embodiment, the left and right sides of the battery protection board can be positioned by the fixed side plate 830 and the movable side plate 840. To position the two ends of the battery protection board, the movable end plate 850 and the Y-axis drive unit 950 can be used in conjunction. The Y-axis drive unit 950 includes a Y-axis drive cylinder 951, a Y-axis moving plate 952, a push plate 953, and a top-mounting platform 954. The Y-axis drive cylinder 951 and the top-mounting platform 954 are respectively mounted on the lifting plate 920, and the top-mounting platform 954 is located in the driving direction of the Y-axis drive cylinder 951. The Y-axis moving plate 952 is connected to the Y-axis drive cylinder 951, and the push plate 953 is located on the Y-axis moving plate 952. The Y-axis drive cylinder 951 can drive the Y-axis moving plate 952 to move, so as to push the push plate 953 toward the top-mounting platform 954.

[0045] When the battery protection board is placed into the placement space of the fixture 800, the actuating ring 944 in the X-axis drive unit 940 will push the movable end plate 850 outward. After the battery protection board is placed, one end will be in the placement space, and the bottom of the other end will be supported by the top platform 954 to prevent it from falling due to its own weight. At this time, the Y-axis drive cylinder 951 will drive the Y-axis moving plate 952 to move, so that the push plate 953 moves towards the top platform 954, and the push plate 953 will push the end of the battery protection board. The device moves and pushes the battery protection board to the set position. Then, the X-axis drive unit 940 resets, and the movable end plate 850 resets under the action of the elastic element 860, positioning and clamping the other end of the battery protection board. At the same time, the fixed side plate 830 and the movable side plate 840 position and clamp the two sides of the battery protection board. Finally, the two sides and two ends of the battery protection board are positioned to ensure that the battery protection board is accurately positioned after being placed in the placement space of the fixture 800. This facilitates the subsequent bending and shaping of the battery protection board and ensures the consistency of the bending of the battery protection board.

[0046] Please see Figure 9After the battery protection board is bent and shaped, it needs to be unloaded and placed in a jig tray for collection. To achieve automatic unloading and collection, the jig return mechanism 700 in this embodiment includes an upper conveyor line 710, a lower conveyor line 720, and a lifting conveyor unit 730. The upper conveyor line 710 and lower conveyor line 720 are arranged vertically, and the lifting conveyor unit 730 is located at the ends of the upper conveyor line 710 and lower conveyor line 720. The lower conveyor line 720 is used to transport the empty jig tray to the lifting conveyor unit 730. The conveying unit 730 is used to lift the empty fixture tray and then convey it to the upper conveyor line 710. The lifting and conveying unit 730 includes a lifting control box 731, a lifting plate 732 and a lifting conveyor line 733. The lifting plate 732 is connected to the lifting control box 731, and the lifting conveyor line 733 is set on the lifting plate 732. The lifting control box 731 is equipped with a motor and a lead screw module. The motor and lead screw module can drive the lifting plate 732 to move up and down, thereby making the lifting conveyor line 733 flush with the upper conveyor line 710 or the lower conveyor line 720.

[0047] An empty jig tray is placed on the lower conveyor line 720 by a robotic arm or manually. The lower conveyor line 720 then transports the empty jig tray to the lifting conveyor line 733 in the lifting conveyor unit 730. The lifting control box 731 then drives the lifting plate 732 to move upward, thereby lifting the lifting conveyor line 733 upward until it is flush with the upper conveyor line 710. At this point, the lifting conveyor line 733 transports the empty jig tray to the upper conveyor line 710, which then transports the empty jig tray and... Once the device reaches the designated position, the unloading robot 600 picks up the bent battery protection board and places it into an empty jig tray for automatic collection. When the empty jig tray is full, the upper conveyor line 710 moves the jig tray again for subsequent removal. The empty jig tray is then placed back into the lower conveyor line 720, and this cycle continues. Ultimately, by automatically conveying and returning the jig trays, the labor intensity of workers can be effectively reduced, and the bending efficiency of the battery protection board can be improved.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
