Description

Technical Field

[0001] This application relates to the field of battery protection plate manufacturing technology, and in particular to a testing device for battery protection plate manufacturing. Background Technology

[0002] The primary driving energy for electric vehicles comes from the batteries inside the vehicle, which are mostly nickel-metal hydride (NiMH) and lithium-ion batteries. In existing technology, electric vehicle batteries are generally rigidly fitted with a protective plate, which is then used to fix them to the vehicle body. A drawback of this battery mounting structure is that the battery is easily damaged by impacts during driving, thus affecting its lifespan, necessitating the installation of a battery protection plate.

[0003] During the production of battery protection panels, they need to be tested by a testing device. However, ordinary testing devices cannot be flipped during operation to test the battery protection panels, and ordinary devices cannot meet the testing requirements of battery protection panels of different sizes. Therefore, we propose a testing device for battery protection panel production. Utility Model Content

[0007] A flipping mechanism is provided between the first and second transfer conveyor belts. The main body of the flipping mechanism is a cylindrical roller. The front and rear ends of the cylindrical roller are rotatably connected between the support frame via a rotating shaft. The outer side of the cylindrical roller has four transfer grooves arranged in a ring array. Several first rollers are evenly rotatably embedded in the support sidewalls of the transfer grooves.

[0008] Each of the four transfer troughs has an adjusting plate movably mounted on its inner side. Each adjusting plate has a pair of adjusting rods fixedly connected to its opposite cross-section. The opposite end faces of the adjusting rods are movably mounted on the outer side of the corresponding triangular adjusting plate. The inner ends of the triangular adjusting plates are fixedly connected to the outer side of the adjusting shaft. The adjusting shaft is movably inserted into the middle of the limiting connecting tube in the middle of the cylindrical roller. The forward displacement of the adjusting shaft drives the triangular adjusting plate to move, thereby driving each adjusting rod to move the corresponding adjusting plate outward to adjust the depth of the transfer trough.

[0009] Preferably, the cylindrical roller has a hollow cavity in the middle.

[0010] Preferably, a limiting connecting pipe is fixedly connected to the middle of the hollow cavity, and four displacement rectangular openings are formed in a ring array on both the front and rear sides of the limiting connecting pipe, and a triangular adjusting plate is movably inserted into the displacement rectangular opening.

[0011] Preferably, the inner side of the limiting connecting tube is provided with a first spring at the front end of the adjusting shaft.

[0012] Preferably, an adjusting screw is movably inserted into the rear side of the inner cavity of the limiting connecting tube. The adjusting screw is threaded through and inserted into the middle of the rear shaft of the cylindrical roller, and a positioning nut is sleeved on the outer side of the adjusting screw.

[0013] Preferably, the outer side of the adjusting rod is movably inserted into the outer wall of the hollow cavity, and spring seats are fixedly connected to opposite sides of the adjusting rod. A second spring is fixedly connected between the spring seats and the outer wall of the hollow cavity.

[0014] Preferably, the two opposite sections of the adjusting rod are rotatably connected to a second roller, and the second roller rotatably overlaps the inclined surface of the triangular adjusting plate.

[0016] Preferably, the width of the transfer trough is equal to the width of the first transfer conveyor belt.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] The structure provided in this application embodiment adjusts the depth of the transfer groove according to the length of the battery guard plate. Specifically, by manually rotating the adjusting screw, the screw is displaced towards the inside of the limiting connecting tube, thereby squeezing and forcing the adjusting shaft forward, causing the triangular adjusting plate to move forward. Under the pressure of the inclined surface of the triangular adjusting plate, the adjusting rod pushes the adjusting plate outward, thereby adjusting and changing the depth of the transfer groove, thus meeting the testing requirements of battery guard plates of different sizes.

[0029] like Figures 1-4 As shown in the figure, this application provides a testing device for battery guard plate production, including:

[0030] First transfer conveyor belt 2 and second transfer conveyor belt 1, the upper ends of the first transfer conveyor belt 2 and the second transfer conveyor belt 1 are fixedly connected to the opposite sides of the upper end of the two conveyor belts 4, the lower end of the support 4 is fixedly connected to the middle of the lower end of the support 4, the upper end of the support 4 is fixedly connected to the left side of the middle of the upper end of the support 4, and the lower end of the transmission plate of the adjustment screw 5 is fixedly connected to the infrared sensor 7.

[0031] The flipping mechanism is set between the first transfer conveyor belt 2 and the second transfer conveyor belt 1. The main body of the flipping mechanism is a cylindrical roller 3. The front and rear ends of the cylindrical roller 3 are rotatably connected between the support frame 10 through a rotating shaft. The outer side of the cylindrical roller 3 has four transfer grooves 8 arranged in a ring array. Several first rollers 12 are evenly rotatably embedded in the support sidewall of the transfer groove 8.

[0032] Each of the four transfer grooves 8 has an adjusting plate 11 movably mounted on its inner side. Each adjusting plate 11 has a pair of adjusting rods 14 fixedly connected to its opposite cross-section. The opposite end faces of the adjusting rods 14 are movably mounted on the outer side of the corresponding triangular adjusting plate 18. The inner ends of the triangular adjusting plates 18 are fixedly connected to the outer side of the adjusting shaft 17. The adjusting shaft 17 is movably inserted into the middle of the limiting connecting pipe 15 in the middle of the cylindrical roller 3. The adjusting shaft 17 moves forward to drive the triangular adjusting plate 18 to move, thereby driving each adjusting rod 14 to move the corresponding adjusting plate 11 outward to adjust the depth of the transfer groove 8.

[0033] Specifically: the infrared sensor 7 adopts a sensor that is already available on the market. The infrared sensor 7 is connected to an external data processing device that receives data via wires and is also connected to a controller; the adjusting screw 5 can be manually rotated to adjust the position of the infrared sensor 7, thereby meeting the detection requirements of battery protection plates of different sizes.

[0034] like Figure 2 As shown, the cylindrical roller 3 has a hollow cavity 13 in the middle.

[0035] like Figure 3 and Figure 4 As shown, a limiting connecting pipe 15 is fixedly connected to the middle of the hollow cavity 13. The front and rear sides of the limiting connecting pipe 15 are arranged in a ring array with four displacement rectangular openings 19. A triangular adjusting plate 18 is movably inserted into the displacement rectangular openings 19.

[0036] Specifically: the triangular adjustment plate 18 moves back and forth inside the displacement rectangular opening 19.

[0037] like Figure 1 As shown, a first spring 16 is provided on the inner side of the limiting connecting tube 15 at the front end of the adjusting shaft 17.

[0038] Specifically: the first spring 16 is always in a compressed state, so that the end of the adjusting shaft 17 is pressed against the end of the adjusting screw 20.

[0039] like Figure 3 As shown, an adjusting screw 20 is movably inserted into the rear side of the inner cavity of the limiting connecting pipe 15. The adjusting screw 20 is threaded through and inserted into the middle of the rear shaft of the cylindrical roller 3, and a positioning nut 21 is sleeved on the outer side of the adjusting screw 20.

[0040] Specifically: the adjusting screw 20 can be turned in both directions to adjust the position of the adjusting shaft 17, and the positioning nut 21 can lock the position of the adjusting screw 20.

[0041] like Figure 3 and Figure 4 As shown, the outer side of the adjusting rod 14 is movably inserted into the outer wall of the hollow cavity 13. Spring seats 23 are fixedly connected to opposite sides of the adjusting rod 14. A second spring 22 is fixedly connected between the spring seat 23 and the outer wall of the hollow cavity 13.

[0042] Specifically: the second spring 22 is always in a compressed state, so that the second roller 24 is in contact with the inclined surface of the triangular adjustment plate 18.

[0043] like Figure 3 and Figure 4 As shown, the two sides of the adjusting rod 14 are rotatably connected to the second roller 24, and the second roller 24 rotatably overlaps the inclined surface of the triangular adjusting plate 18.

[0044] Specifically, the second roller 24 enables the adjusting rod 14 to move up and down more smoothly.

[0045] like Figure 1 As shown, the front end shaft of the cylindrical roller 3 is fixedly connected to a drive motor 9, and the drive motor 9 is fixedly connected to the front end of the support frame 10.

[0046] Specifically: The drive motor 9 uses an existing motor on the market, which is a current technology. The drive motor 9 is equipped with a dedicated controller to control the drive motor 9 to rotate 90 degrees each time.

[0047] like Figure 1 As shown, the width of the transfer trough 8 is equal to the width of the first transfer conveyor belt 2.

[0048] Specifically: The inside of the transfer groove 8 can transfer and flip the battery guard plate, thereby enabling the sampling and testing of both sides of the battery guard plate.

[0049] Principle: When the equipment is in use, the battery guard plate is transferred from the first transfer conveyor belt 2 to the left, flipped by the cylindrical roller 3, and transferred to the upper end of the second transfer conveyor belt 1 to the left. Then, the qualified products are separated from the unqualified products by the external robotic arm.

[0050] Furthermore, the drive motor 9 is connected to an external controller, which controls the drive motor 9 to rotate 90 degrees each time. This ensures that after each rotation, the new transfer groove 8 faces the upper end of the first transfer conveyor belt 2, so that the battery guard plate transferred at the upper end of the first transfer conveyor belt 2 can be transferred and inserted into the corresponding transfer groove 8.

[0051] Before use, the depth of the transfer groove 8 is adjusted according to the length of the battery guard plate. This is achieved by manually rotating the adjusting screw 20 to move it towards the inside of the limiting connecting pipe 15, thereby squeezing and forcing the adjusting shaft 17 forward, causing the triangular adjusting plate 18 to move forward. Under the pressure of the inclined surface of the triangular adjusting plate 18, the adjusting rod 14 pushes the adjusting plate 11 outward, thereby adjusting and changing the depth of the transfer groove 8. This allows the battery guard plate to be tested for different sizes, so that when the battery guard plate is flipped and transferred, it can extend a portion of the battery guard plate out of the transfer groove 8. After the battery guard plate is flipped, it can be moved to the upper end of the second transfer conveyor belt 1 for transfer by the transmission of the second transfer conveyor belt 1.

[0052] During the testing process, the first transfer conveyor belt 2 transports the battery cover to the left. After the infrared sensor 7 on the upper left side of the first transfer conveyor belt 2 detects that the battery cover has moved to the set position, the high-definition camera 6 is activated to take multiple pictures for sampling. The battery cover is then transferred to the transfer trough 8, where the drive motor 9 rotates 90 degrees to transfer the battery cover to another transfer trough 8 for retesting. The drive motor 9 then rotates 90 degrees again, flipping the battery cover from the first test and transporting it to the upper end of the second transfer conveyor belt 1 for leftward transport. After the infrared sensor 7 on the upper end of the second transfer conveyor belt 1 detects that the battery cover has moved to the set position, the high-definition camera 6 on the upper end of the second transfer conveyor belt 1 is activated to take multiple pictures for sampling. This samples the image of the back of the battery cover, and the two sets of images are uploaded to an external image processing device for surface integrity analysis, thereby detecting defective products.

[0053] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
