Description

Technical Field

[0001] This invention relates to a processing equipment for battery bases of new energy vehicles, and more particularly to an automatic removal device and method for removing plugs during the processing of battery bases of new energy vehicles. Background Technology

[0002] New energy batteries are typically housed in a sturdy aluminum alloy protective casing, also known as a battery base. During the production process, the casing needs to be coated with waterproof and corrosion-resistant materials such as epoxy resin and graphite. Because the casing has multiple holes for subsequent wiring, these holes must be reliably covered before the waterproof material is applied to prevent it from entering the casing. Current methods involve attaching specially shaped stickers to the holes, which are then manually removed after coating. However, since the casing surface is completely covered by epoxy resin and graphite, workers must use a knife and experience to cut the edges of the sticker before peeling it off by hand. This process is highly dependent on worker experience, and the sticker's adhesion to the casing becomes strong after heating, making the operation difficult and the environment harsh. Summary of the Invention

The side removal mechanism includes a translation mechanism, a lifting mechanism, and a flat panel. The lifting mechanism is mounted on the translation mechanism and can be driven by the translation mechanism to translate to both sides of the plug removal mechanism. The flat panel is connected to the lifting mechanism and can be lifted and lowered by the lifting mechanism. A second slot is provided at the bottom of the flat panel.

[0005] The plug includes a plug body, a material-receiving rod, and a limiting ball.

[0006] The plug body includes a locking part that matches the shape of the corresponding opening of the battery base, and a top cover that extends uniformly outward from the edge of the locking part on the surface of the locking part, and the material picking rod is located on the front of the top cover.

[0007] The limiting ball is located on the side of the engaging part and extends outward relative to the side of the engaging part. A spring is provided between the bottom of the limiting ball and the engaging part.

[0008] As an improvement to the above solution, the transmission mechanism includes a transmission wheel, a transmission belt, a transmission shaft, and a transmission motor; the transmission belt has transmission wheels at both ends, the transmission shaft connects the transmission wheels on both sides, and the transmission motor is connected to the transmission shaft to drive the transmission shaft to rotate.

[0009] As an improvement to the above solution, the positioning mechanism includes a positioning slide rail, a positioning lifting cylinder, a positioning slide block, and a positioning rod. The positioning slide rail is vertically arranged, and the positioning slide block is sleeved on the positioning slide rail and can slide along the positioning slide rail. The top of the positioning slide block is provided with a lifting plate, and the positioning rod extends upward relative to the lifting plate. The top of the positioning rod is provided with a positioning tip. The positioning lifting cylinder is connected to the lifting plate and is used to drive the lifting plate to rise and fall.

[0010] As an improvement to the above solution, the rotating shaft is connected to the front and rear telescopic cylinders, which are used to drive the rotating shaft to rotate a predetermined angle; in the initial state, the end of the arc-shaped plate faces downward.

[0011] As an improvement to the above solution, the translation mechanism includes a lateral telescopic cylinder, a lateral slide rail, and a lateral slide block mounted on the top beam of the frame. The lateral telescopic cylinder is connected to the lateral slide block, and the lateral slide block is configured to cooperate with the lateral slide rail. The lifting mechanism includes a lifting cylinder connected to the lateral slide block, and the lifting cylinder is also connected to the flat plate.

[0012] As an improvement to the above solution, the planar plate has a lower end face at different heights, and the second slot extends upward from the lower end face.

[0013] As an improvement to the above solution, the engaging part is provided with clearance parts on both sides, and the surface of the clearance parts is arc-shaped; the end of the picking rod is provided with a blocking block, the blocking block is disc-shaped, and the diameter of the blocking block is larger than the diameter of the picking rod.

[0014] As an improvement to the above solution, the plug also includes a protective ring that covers the sides and bottom of the top cover.

[0015] Accordingly, this invention also provides a method for automatically removing the plugs from the battery base of a new energy vehicle, which uses the automatic plug removal equipment for the battery base of a new energy vehicle as described above, and includes the following steps:

[0016] S1. The transmission mechanism drives the battery base to the predetermined work position. The positioning lifting cylinder drives the positioning rod to rise. The positioning tip of the positioning rod contacts the reserved positioning hole at the bottom of the battery base, lifting and guiding the battery base.

[0017] S2. The rotating shaft of the front and rear removal mechanism drives the arc plate to swing downward, inserting the material-retrieving rod of the plug located below into the first slot. Then, the arc plate continues to rotate, pulling out the plug. The lifting mechanism of the side removal mechanism drives the flat plate to move downward, inserting the material-retrieving rod of the plug on both sides of the battery base into the second slot. Then, the translation mechanism drives the flat plate to move outward, pulling out the plug. The pulled-out plug falls into the collection container below under the action of gravity.

[0018] S3, the curved plate and flat panel are reset, and the battery base with the plug removed is sent out through the transmission mechanism.

[0019] Implementing the embodiments of the present invention has the following beneficial effects:

[0020] Using this plug, before spraying the anti-corrosion paint, simply select the corresponding plug according to the shape of each hole in the protective shell, insert its engaging part into the corresponding hole, and when the engaging part is in place, the limiting ball will just pass over the protective shell and reach the inside of the protective shell. The limiting ball will then pop out, and together with the top cover, fix the plug in the hole, making installation convenient. After the painting is completed, the material picking rod will remain extended outward. At this time, an automatic removal device can be used to clamp the material picking rod and pull the plug out of the hole, making disassembly convenient. After disassembly, the epoxy resin graphite adhering to the surface of the plug can be removed with organic solvents such as thinner, and after drying, it can be reused, which is energy-saving and environmentally friendly.

[0021] The automatic removal equipment has a compact structure, automatic positioning and plug removal functions, strong adaptability, high fault tolerance, and stable and reliable operation. The front and rear removal mechanisms target plugs at the front and rear of the battery base. Since the front and rear ends of the battery base are often uneven, the plugs are also at different angles. Through the design of the rotating shaft and arc plate, it can penetrate deep into the inclined surface. The rotation of the arc plate forms an arc-shaped movement trajectory, locking the first slot into the picking rod. The sides of the battery base are usually vertical planes. Through the translation mechanism, lifting mechanism, and flat panel of the side removal mechanism, plugs at different heights on the sides of the battery base can be pulled out uniformly. By replacing different flat plates, different battery bases can be matched. The structure is simple, the function is flexible, and it has strong adaptability. Attached Figure Description

It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0031] like Figures 1-6 As shown, the first embodiment of the present invention provides an automatic plug removal device for processing battery bases of new energy vehicles, including a transmission and positioning seat 100, a plug removal mechanism 200, and a plug 300; the transmission and positioning seat 100 includes a transmission mechanism 1 and a positioning mechanism 2, the transmission mechanism 1 is used to transmit the battery base to a predetermined area, and the positioning mechanism 2 is used to adjust and fix the position of the battery base that arrives at the predetermined area; the plug removal mechanism 200 includes a front and rear removal mechanism 3 and a side removal mechanism 4, the front and rear removal mechanism 3 includes a rotating shaft 31 and an arc plate 32 disposed on the rotating shaft 31, the arc plate 32 is provided with a first slot 33; the side removal mechanism 4 includes a translation mechanism 41, a lifting mechanism 42, and a flat plate 43, the lifting mechanism 42 is disposed on the translation mechanism 41 and can be driven by the translation mechanism 41 to translate to both sides of the plug removal mechanism 200; the flat plate 43 is connected to the lifting mechanism 42 and can be driven by the lifting mechanism 42 to rise and fall; the lower part of the flat plate 43 is provided with a second slot 44.

[0032] The plug 300 includes a plug body 5, a material-receiving rod 6, and a limiting ball 7.

[0033] The plug body 5 includes a locking part 51 that matches the shape of the corresponding opening of the battery base, and a top cover 52 that extends uniformly outward from the edge of the locking part 51 on the surface of the locking part 51. The material picking rod 6 is located on the front of the top cover 52.

[0034] The limiting ball 7 is located on the side of the engaging part 51 and extends outward relative to the side of the engaging part 51. A spring 8 is provided between the bottom of the limiting ball 7 and the engaging part 51.

[0035] The transmission mechanism 1 includes a transmission wheel 11, a transmission belt 12, a transmission shaft 13, and a transmission motor 14. The transmission belt 12 is provided with the transmission wheel 11 at both ends, the transmission shaft 13 is connected to the transmission wheel 11 on both sides, and the transmission motor 14 is connected to the transmission shaft 13 to drive the transmission shaft 13 to rotate.

[0036] Using this plug 300, before spraying the anti-corrosion paint, simply select the corresponding plug 300 according to the shape of each hole in the protective shell, and insert its engaging part 51 into the corresponding hole. When the engaging part 51 is in place, the limiting ball 7 will just pass over the shell of the protective shell and reach the inside of the protective shell. The limiting ball 7 will pop out, and together with the top cover 52, fix the plug 300 in the hole, making installation convenient. After the painting is completed, its picking rod 6 will remain extended outward. At this time, an automatic removal device can be used to clamp the picking rod 6 and pull the plug 300 out of the hole, making disassembly convenient. After disassembly, the epoxy resin graphite adhering to the surface of the plug 300 can be removed with organic solvents such as thinner. After drying, it can be reused, which is energy-saving and environmentally friendly.

[0037] The automatic removal equipment has a compact structure, automatic positioning and plug removal functions, strong adaptability, high fault tolerance, and stable and reliable operation. The front and rear removal mechanism 3 targets the plugs at the front and rear of the battery base. Since the front and rear ends of the battery base are often uneven, the plugs are also in a tilted state at different angles. Through the design of the rotating shaft 31 and the arc plate 32, it can penetrate deep into the tilted surface. The rotation of the arc plate 32 forms an arc-shaped movement trajectory, locking the first slot 33 into the picking rod 6. The sides of the battery base are usually vertical planes. Through the translation mechanism 41, lifting mechanism 42, and flat panel 43 of the side removal mechanism 4, plugs at different heights on the sides of the battery base can be pulled out uniformly. By replacing different flat plates 43, different battery bases can be matched. The structure is simple, the function is flexible, and the adaptability is strong.

[0038] Specifically, the positioning mechanism 2 includes a positioning slide rail 21, a positioning lifting cylinder 22, a positioning slide block 23, and a positioning rod 24. The positioning slide rail 21 is vertically arranged, and the positioning slide block 23 is sleeved on the positioning slide rail 21 and can slide along the positioning slide rail 21. The top of the positioning slide block 23 is provided with a lifting plate 25, and the positioning rod 24 extends upward relative to the lifting plate 25. The top of the positioning rod 24 is provided with a positioning tip 241. The positioning lifting cylinder 22 is connected to the lifting plate 25 and is used to drive the lifting plate 25 to rise and fall.

[0039] The rotating shaft 31 is connected to the front and rear telescopic cylinders 34, which are used to drive the rotating shaft 31 to rotate a predetermined angle. In the initial state, the end of the arc plate 32 faces downward so that the battery base can pass through.

[0040] The translation mechanism 41 includes a lateral telescopic cylinder 411, a lateral slide rail 412, and a lateral slide block 413 mounted on the top beam 9 of the frame. The lateral telescopic cylinder 411 is connected to the lateral slide block 413, and the lateral slide block 413 is configured to cooperate with the lateral slide rail 412. The lifting mechanism 42 includes a lifting cylinder 421 connected to the lateral slide block 413, and the lifting cylinder 421 is also connected to the flat plate 43. By mounting the lateral telescopic cylinder 411, the lateral slide rail 412, and the lateral slide block 413 on the top beam 9 of the frame, the space of the frame can be fully utilized, reducing the overall height of the frame. Moreover, the above mechanisms are directly connected by cylinders, which can reduce the overall weight of the translation mechanism 41, reduce energy consumption, reduce movement inertia, and make the operation more stable.

[0041] To accommodate plugs at different heights, the flat plate 43 has a lower end face at different heights, and the second slot 44 extends upward from the lower end face.

[0042] Combination Figure 8 As shown, preferably, the engaging portion 51 has clearance portions 53 on both sides, and the surface of the clearance portions 53 is arc-shaped; the end of the material-taking rod 6 has a blocking block 61, which is disc-shaped and has a diameter larger than that of the material-taking rod 6. The arc-shaped surface of the clearance portions 53 can reduce the possibility of interference between the engaging portion 51 and the internal structure of the protective shell, improve the adaptability of the plug, and increase the applicable occasions of the plug.

[0043] Combination Figure 7As shown, preferably, the plug 300 further includes a protective ring 54, which covers the side and bottom surfaces of the top cover 52. Cleaning the plug 300 after each use would significantly increase production costs. Therefore, in this embodiment, the top cover 52 has protective rings 54 on its side and back. The protective rings 54 are directly inserted into the top cover 52 from the engaging part 51. By adding the protective rings 54, they can be individually removed, replaced, and cleaned after each use, thus ensuring that the bottom surface of the top cover 52 in contact with the corresponding hole of the protective shell remains clean. The plug 300 can be cleaned after several uses, further improving production efficiency and reducing production losses.

[0044] Accordingly, the second embodiment of the present invention also provides a method for automatically removing the plugs in the processing of new energy vehicle battery bases, which uses the automatic plug removal equipment for new energy vehicle battery bases as described above, and includes the following steps:

[0045] S1. The transmission mechanism 1 drives the battery base to the predetermined work position. The positioning lifting cylinder 22 drives the positioning rod 24 to rise. The positioning tip 241 of the positioning rod 24 contacts the reserved positioning hole at the bottom of the battery base, lifting and guiding the battery base.

[0046] S2. The rotating shaft 31 of the front and rear removal mechanism 3 drives the arc plate 32 to swing downward, and insert the picking rod 6 of the plug 300 located below into the first slot 33. Then the arc plate 32 continues to rotate and pulls out the plug 300. The lifting mechanism 42 of the side removal mechanism 4 drives the flat plate 43 to move downward, and insert the picking rod 6 of the plug 300 on both sides of the battery base into the second slot 44. Then, the translation mechanism 41 drives the flat plate 43 to move outward and pull out the plug 300. The pulled-out plug 300 falls into the collection container below under the action of gravity.

[0047] S3, the arc plate 32 and the flat panel 43 are reset, and the battery base with the plug 300 pulled out is sent out through the transmission mechanism 1.

[0048] Using the above method, the plugs around the battery base can be automatically removed. The equipment has a high fault tolerance rate and is easy to maintain. The battery base is first supported and positioned by the positioning tip 241 of the positioning rod 24, which ensures that each battery base is in the same position and that the battery base will not move during the removal of the plugs 300. The plugs 300 in different parts of the battery base are removed uniformly by the arc plate 32 and the flat plate 43, which can adapt to the contour features of different surfaces of the battery base, making it highly targeted and reliable.

[0049] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
