Description

Technical Field

[0001] This utility model relates to the field of insulating cover processing technology, specifically to a vacuum forming machine. Background Technology

[0002] The application of CCS (Compactor Controlled Busbar) insulating covers is mainly concentrated in lithium battery modules and energy storage fields. CCS, also known as "integrated busbar" or "wire harness board integration," is a new type of connector used in lithium battery modules. It is an integrated component consisting of multiple systems, including a metal electrical connection system, a signal sampling system, and an insulation system. CCS insulating covers are typically used as part of the insulation system to isolate and protect the electrical connections in the battery module, preventing safety issues such as short circuits and electric shocks.

[0003] In lithium battery modules, CCS thermoformed insulating covers are widely used in commercial vehicles, passenger vehicles, and other fields. They effectively isolate the positive and negative electrodes and signal lines within the battery module, preventing short circuits caused by contact between metal parts or intrusion of external objects.

[0004] The traditional production method of vacuum-formed insulation covers is as follows: S1. Vacuum forming process: Workers manually place the sheet insulation cover material in the vacuum forming area, and then use a heating device to heat the sheet insulation cover material until it softens. The forming device then adsorbs the softened sheet insulation cover material onto the surface of the forming device, forming the required shape. Afterwards, it is hardened and shaped by cooling or natural cooling to obtain a semi-finished insulation cover. S2. Punching process: The semi-finished insulation cover is manually transported by workers to the punching device, which punches out the specified shape and internal circular hole shape to obtain the finished insulation cover. S3. Appearance inspection process: The finished insulation cover is manually transported by workers to the appearance inspection area. The finished insulation cover is manually dusted and its appearance is visually inspected to determine if there are any defects. Finally, workers separate the finished insulation cover with appearance defects from those without.

[0005] However, manually placing the sheet-like insulating material into the vacuum forming area results in low production efficiency for insulating covers. Therefore, improving the production efficiency of insulating cover vacuum forming is a pressing technical problem that needs to be solved in this field. Utility Model Content

[0031] Finished insulating cover 3. Detailed Implementation

[0032] This utility model provides a vacuum forming machine that overcomes the shortcomings of manually placing sheet-shaped insulating cover material in the vacuum forming operation area in the prior art; it realizes the technical effect of continuously entering the vacuum forming operation area with roll-shaped insulating cover material, thereby improving the production efficiency of insulating cover vacuum forming.

[0033] The overall concept of the technical solution of this utility model embodiment is as follows:

[0034] The feeding device carries wound insulating cover material. This material moves from the feeding device to the vacuum forming area, where it is heated and softened to become a primary part. After being vacuum-formed, it becomes a secondary part, and after cooling and hardening, it becomes a tertiary part. A pulling robot then pulls the tertiary part from the vacuum forming area to the cutting area. Since the tertiary part is still connected to the insulating cover material at this point, it pulls the insulating cover material from the feeding device into the vacuum forming area. The cutting device cuts the tertiary part, thus separating it from the insulating cover material and creating a semi-finished insulating cover. In the vacuum forming area, the insulating cover material continues to be heated, softened, vacuum-formed, and cooled to harden. The semi-finished insulating covers are then placed one by one, orderly, by the pulling robot onto the first conveyor belt device.

[0035] The first conveyor belt transports the semi-finished insulating cover to the punching device of the punching machine. After punching, the semi-finished insulating cover obtains the specified shape and internal circular hole shape, becoming the finished insulating cover. The finished insulating cover is then conveyed by the second conveyor belt to the dust removal and appearance inspection area.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] See Figures 1 to 11 The preferred embodiment of this utility model.

[0038] A vacuum forming machine 1, comprising:

[0039] 11. Feeding device 12. Heating device 13. Forming device 14. Cooling device 15. Material pulling robot 16. Cutting device 17. and vacuum forming frame 18;

[0040] The vacuum forming frame 18 has a vacuum forming operation area. The feeding device 11 is located in front of the vacuum forming frame 18 and is equipped with wound insulating cover material. The material pulling robot 15 is located behind the vacuum forming frame 18. The cooling device 14 is fixedly installed on the vacuum forming frame 18 and is located above the vacuum forming operation area. The forming device 13 is slidably connected to the vacuum forming frame 18 vertically and is located below the vacuum forming operation area. The heating device 12 is slidably connected to the vacuum forming frame 18 horizontally and is located between the vacuum forming operation area and the cooling device 14. The cutting device 16 is slidably connected to the vacuum forming frame 18 horizontally and is located between the outlet of the vacuum forming operation area and the material pulling robot 15.

[0041] The beneficial effects of this utility model are as follows: through the cooperation of the material pulling robot 15 and the cutting device 16, the roll-shaped insulating cover raw material is continuously fed into the vacuum forming operation area, and after heating, forming, cooling and cutting, the semi-finished insulating cover is obtained in an orderly manner, thereby improving the vacuum forming production efficiency of the insulating cover.

[0042] The insulating cover material is moved from the feeding device 11 to the vacuum forming area. After being heated and softened by the heating device 12, it becomes a primary material. After being adsorbed and formed by the forming device 13, it becomes a secondary material. After being cooled and hardened by the cooling device 14, it becomes a tertiary material. The pulling robot 15 pulls the tertiary material from the vacuum forming area to the cutting area. Since the tertiary material is connected to the insulating cover material at this time, the tertiary material pulls the insulating cover material located in the feeding device 11 to the vacuum forming area. The cutting device 16 cuts the tertiary material, so that the tertiary material is disconnected from the insulating cover material and becomes a semi-finished insulating cover.

[0043] The insulating cover material located in the feeding device 11 is a roll of plastic film. The feeding device 11 includes a feeding shaft 111 and an auxiliary guiding mechanism 112. The insulating cover material is wound around the feeding shaft 111 and passes between the pinch rollers of the auxiliary guiding mechanism 112 before entering the thermoforming area. Feeding the insulating cover material in roll form helps the material to continuously enter the thermoforming area, improving production efficiency.

[0044] The heating device 12, forming device 13, cooling device 14, and cutting device 16 work together in an orderly manner. The heating device 12 first moves between the vacuum forming area and the cooling device 14 to heat the insulating cover material; after heating is completed, the heating device 12 withdraws from between the vacuum forming area and the cooling device 14 to avoid interfering with the air blowing cooling of the cooling device 14.

[0045] Furthermore, the vacuum forming machine 1 also includes a positioning device 17, which includes a cover frame 171, a slide rod 172, and a drive block 173. The cover frame 171 is fixedly disposed at the upper end of the slide rod 172, and the drive block 173 is fixedly disposed at the lower end of the slide rod 172. The slide rod 172 is also slidably connected to the vacuum forming frame 18. A material inlet positioning port is formed between the cover frame 171 and the front end of the vacuum forming frame 18, and a material outlet positioning port is formed between the cover frame 171 and the rear end of the vacuum forming frame 18. The middle of the cover frame 171 is the vacuum forming operation area.

[0046] The beneficial effects of this technical solution are as follows: The insulating cover material enters the vacuum forming operation area through the inlet positioning port and then reaches the outlet positioning port; the drive block 173 lowers the cover frame 171 via the slide rod 172 to press and position the insulating cover material; then the insulating cover material is sequentially heated and softened, adsorbed and shaped, and cooled and hardened to obtain a three-stage material; finally, the drive block 173 raises the cover frame 171 via the slide rod 172 to release the three-stage material. The gripper of the pulling robot 15 clamps the three-stage material from the outlet positioning port and pulls the three-stage material to the cutting operation area, where the cutting device 16 cuts the three-stage material and the insulating cover material.

[0047] Furthermore, the heating device 12 is a heating furnace.

[0048] Furthermore, the forming device 13 is a vacuum suction mold. The vacuum suction mold is a mold that generates suction through vacuum, and suction holes are distributed on the forming surface of the mold. The vacuum suction mold moves upwards to the vacuum forming area, the suction holes hold the primary material, and the primary material is adsorbed onto the forming surface of the mold to form the desired shape, resulting in the secondary material; then the suction holes release the secondary material, and the vacuum suction mold moves downwards to detach from the secondary material.

[0049] Furthermore, the cooling device 14 is a blower.

[0050] Furthermore, the cutting device 16 is a cutting blade.

[0051] Specific application description of the vacuum forming machine 1 of this utility model in the vacuum forming process:

[0052] The insulating cover material is fed into the vacuum forming machine 1, which includes a feeding device 11, a heating device 12, a forming device 13, a cooling device 14, a material pulling robot 15, and a cutting device 16.

[0053] The insulating cover material is first wound and installed on the feeding device 11, and then moved from the feeding device 11 to the thermoforming operation area;

[0054] The heating device 12 heats the insulating cover material in the vacuum forming area, and the insulating cover material softens due to heating and becomes a primary material.

[0055] The forming device 13 adsorbs the primary material in the vacuum forming operation area. The primary material becomes a secondary material because it is adsorbed on the surface of the forming device 13. The forming device 13 then detaches from the secondary material.

[0056] The cooling device 14 cools the secondary material in the thermoforming area, and the secondary material hardens due to cooling, becoming a tertiary material;

[0057] The material pulling robot 15 pulls the third-level material from the vacuum forming operation area to the cutting operation area, and at the same time, the third-level material pulls the insulating cover material located in the feeding device 11 to the vacuum forming operation area.

[0058] The cutting device 16 cuts the third-level material in the cutting operation area, and the third-level material becomes a semi-finished insulation cover because it is disconnected from the insulation cover raw material.

[0059] The function of the vacuum forming machine 1: The vacuum forming machine 1 heats the plastic roll material through the heating device 12 to soften it, making it easier for subsequent forming operations. At the same time, it uses the vacuum suction mold to adsorb the softened plastic roll material onto the forming surface of the mold to form the required shape. Afterwards, the plastic is hardened and shaped by the cooling device 14 or by natural cooling.

[0060] Specifically, the insulating cover material is fed from the feeding shaft 111, passes through the auxiliary guiding mechanism 112, and arrives above the vacuum suction mold. During vacuum forming, the heating furnace moves between the vacuum forming area and the blower to heat the insulating cover material (usually for 10-15 seconds) to soften it and make it formable, thus obtaining the primary part. After heating, the heating furnace returns to its original position, and the vacuum suction mold rises to the height of the primary part. Then, the primary part is adsorbed onto the forming surface of the vacuum suction mold (usually for 7-10 seconds). After the vacuum forming process is complete, the vacuum suction mold descends, thus completing the demolding process and obtaining the secondary material. Simultaneously, a blower rapidly cools the secondary material (typically for 5-8 seconds), causing it to harden and become the tertiary material. The material-pulling robot 15 moves and approaches the tertiary material, its grippers clamping it and pulling it from the vacuum forming area to the cutting area. At this point, the cutter cuts the tertiary material from the insulating cover material, obtaining a semi-finished insulating cover. The material-pulling robot then places the semi-finished insulating cover on the first conveyor belt device 21. This completes the entire process.

[0061] The following is an explanation of how the semi-finished insulating cover is transformed into finished insulating cover 3 through a punching process:

[0062] The semi-finished insulating cover is fed into the punching machine 2, which includes a first conveyor belt device 21, a feeding robot 22, a punching device 23, a discharging robot 24, and a second conveyor belt device 25.

[0063] The material pulling robot 15 places the semi-finished insulating cover onto the first conveyor belt device 21;

[0064] The first conveyor belt device 21 transports the semi-finished insulating cover to the handling area of ​​the loading robot 22;

[0065] The loading robot 22 transfers the semi-finished insulating cover from the first conveyor belt device 21 to the punching device 23;

[0066] The punching device 23 punches the product shape of the insulation cover semi-finished product, and the insulation cover semi-finished product becomes the insulation cover finished product 3.

[0067] The unloading robot 24 transfers the finished insulating cover 3 from the punching device 23 to the second conveyor belt device 25;

[0068] With the cooperation of the first conveyor belt device 21 and the loading robot 22, the semi-finished insulation cover is automatically transported to the punching device 23 to achieve automated punching and obtain the finished insulation cover 3. Then, with the cooperation of the second conveyor belt device 25 and the unloading robot 24, the finished insulation cover 3 is taken away. The finished insulation cover 3 is sent to the dust removal and appearance inspection area by the second conveyor belt device 25.

[0069] Furthermore, the punching device 23 includes a base 231, a top seat 232, a die 233, and an insulating cover placement platform 234. The top seat 232 is vertically connected to the base 231, the die 233 is fixedly connected to the top seat 232, the area below the die 233 is the punching operation area, and the insulating cover placement platform 234 is slidably connected to the base 231. The insulating cover placement platform 234 can enter and exit the punching operation area.

[0070] The beneficial effects of this technical solution are as follows: When the insulating cover placement platform 234 exits the punching operation area, the loading robot 22 places the insulating cover semi-finished product on the insulating cover placement platform 234. The loading robot 22 does not need to enter the punching operation area, thus improving loading efficiency. The insulating cover placement platform 234 transports the insulating cover semi-finished product into the punching operation area, and the die 233 descends to punch out the required shape and internal circular hole shape on the insulating cover semi-finished product. Then, the insulating cover placement platform 234 transports the insulating cover finished product 3 out of the punching operation area, and the unloading robot 24 takes the insulating cover finished product 3 from the insulating cover placement platform 234. The unloading robot 24 does not need to enter the punching operation area, thus improving unloading efficiency.

[0071] Both the loading robot 22 and the unloading robot 24 are equipped with suction cups.

[0072] Furthermore, the punching device 23 also includes a support plate 235 and a guide rail 236. The guide rail 236 is fixedly mounted on the base 231 and is located within the punching operation area. The insulating cover placement platform 234 slides along the guide rail 236. The support plate 235 is fixedly mounted on the base 231 and is located outside the punching operation area. When the insulating cover placement platform 234 exits the punching operation area, the lower surface of the insulating cover placement platform 234 contacts the support plate 235.

[0073] The beneficial effects of this technical solution are: when the insulating cover placement platform 234 is outside the punching operation area, the support plate 235 improves the stability of the insulating cover placement platform 234 when transferring materials.

[0074] Furthermore, the punching device 23 also includes a hydraulic cylinder 237, a first column 238, a second column 239, a first rotating shaft 2391, a second rotating shaft 2392, a first angle plate 2393, a second angle plate 2394, a connecting rod 2395, a first adapter block 2396, and a second adapter block 2397. The upper end of the first column 238 is fixedly disposed at the front end of the top seat 232, and the lower end of the first column 238 is fixedly disposed at the first adapter block 2396. The first column 238 is also vertically disposed at the front end of the base 231. The upper end of the second column 239 is fixedly disposed at the rear end of the top seat 232, and the lower end of the second column 239 is fixedly disposed at the second adapter block 2397. The second column 239 is also vertically disposed at the front end of the base 231. At the rear end of 31, the cylinder body of the hydraulic cylinder 237 is fixedly mounted on the base 231. The telescopic end of the hydraulic cylinder 237 is fixedly connected to the first adapter block 2396. The middle part of the first angle plate 2393 is fixedly connected to the first rotating shaft 2391. The front end of the first angle plate 2393 is hinged to the first adapter block 2396. The rear end of the first angle plate 2393 is hinged to the front end of the connecting rod 2395. The middle part of the second angle plate 2394 is fixedly connected to the second rotating shaft 2392. The front end of the second angle plate 2394 is hinged to the rear end of the connecting rod 2395. The rear end of the second angle plate 2394 is hinged to the second adapter block 2397. The first rotating shaft 2391 and the second rotating shaft 2392 are both rotatably connected to the base 231.

[0075] The beneficial effects of this technical solution are as follows: When the hydraulic cylinder 237 drives the first transition block 2396 to rise and fall, the second transition block 2397 is raised and lowered synchronously with the help of the first corner plate 2393, the second corner plate 2394, and the connecting rod 2395. Then, through the first column 238 and the second column 239, the front and rear ends of the top seat 232 are raised and lowered synchronously, thereby improving the punching stability of the die 233.

[0076] The function of punching machine 2 is to shear and punch the semi-finished insulating cover using the pressure of die 233 and hydraulic cylinder 237. The loading robot 22 and unloading robot 24 are mainly used to automate loading and unloading.

[0077] Specifically, the punching device 23 punches out the desired shape and internal circular hole shape. First, the semi-finished insulating cover delivered by the first conveyor belt device 21 is picked up by the loading robot 22 and placed on the insulating cover placement platform 234 of the punching device 23. The insulating cover placement platform 234 is equipped with auxiliary positioning points. The platform slides into the punching device 23 via a slide rail and is positioned below the die 233. The die 233 is locked to the top seat 232 by clamping blocks. Then, the top seat 232, carrying the die 233, punches downwards. Guided by four columns and hydraulic cylinders 237, significant pressure is generated to punch and shape the insulating cover, resulting in the finished insulating cover 3. After punching, the insulating cover placement platform 234 moves outwards, while the die 233 rises back to its original position. This completes the entire operation.
