Description

Technical Field

[0001] This invention relates to the field of automotive battery connector manufacturing, and in particular to an automotive battery connector stamping apparatus. Background Technology

[0002] Car batteries vary slightly depending on the type of electric vehicle. In pure electric vehicles equipped only with a battery, the battery is the sole power source for the vehicle's drive system. In hybrid electric vehicles equipped with both a traditional engine and a battery, the battery can act as either the primary or auxiliary power source for the drive system. When the vehicle starts or travels at low speeds, the battery acts as the primary power source; during full-load acceleration, the battery acts as an auxiliary power source; and during normal driving, deceleration, or braking, the battery stores energy. The battery connector refers to the connection point between the car battery and the external electrical system; it is a crucial component of the car battery.

[0003] However, the production process of automotive battery connectors requires the use of a stamping device to stamp the raw material plate. Traditional stamping equipment, such as the technical solution protected by the patent application number CN201420373193.0, entitled "Stamping Machine", may cause material damage due to changes in the position of the plate during the stamping process.

[0022] Please refer to the following: Figures 1 to 3 The present invention provides an automotive battery connector stamping device 10, which includes: a receiving platform 100, a connecting platform 200, a stamping mechanism 300, two fixing mechanisms 400 and a control mechanism 500.

[0023] The connecting platform 200 is set on the receiving platform 100.

[0024] The stamping mechanism 300 includes a hydraulic cylinder 310, an upper support plate 320, an upper stamping die 330, a lower support plate 340, and a lower stamping die 350. The hydraulic cylinder 310 is connected to the end of the connecting platform 200 away from the receiving platform 100, and the driving end of the hydraulic cylinder 310 is connected to the upper support plate 320. The upper stamping die 330 is disposed on the side of the upper support plate 320 facing away from the hydraulic cylinder 310. The lower support plate 340 is disposed on the receiving platform 100, and the lower stamping die 350 is disposed on the side of the lower support plate 340 facing away from the receiving platform 100. The hydraulic cylinder 310 drives the upper stamping die 330 to move closer to or further away from the lower stamping die 350 via the upper support plate 320.

[0025] Two fixing mechanisms 400 are symmetrically arranged at both ends of the lower stamping die 350. Each fixing mechanism 400 includes a fixing platform 410, a fixing support plate 420, a rotating rod 430, a rotating handle 440, and a limiting assembly 450. The fixing platform 410 is connected to the lower support plate 340, and the fixing support plate 420 is connected to the fixing platform 410. The fixing support plate 420 has a threaded hole 401. The rotating rod 430 has an external thread and is inserted into the threaded hole 401 and screwed to the fixing support plate 420. The rotating handle 440 is connected to one end of the rotating rod 430. A rotating groove 402 is formed at the end of the rotating rod 430 away from the rotating handle 440. A rotating cavity 403 is formed at the bottom of the rotating groove 402, and the size of the rotating cavity 403 is larger than that of the rotating groove 402. The limiting assembly 450 includes a rotating plate 451, a rotating column 452, and a limiting plate 453. The limiting plate 453 is connected to the rotating plate 451 via the rotating column 452. The rotating column 452 is adapted to the rotating groove 402, is inserted into the rotating groove 402, and is rotatably connected to the rotating rod 430. The rotating plate 451 is adapted to the rotating cavity 403, is inserted into the rotating cavity 403, and is rotatably connected to the rotating rod 430. The limiting plate 453 can move back and forth above the lower stamping die 350.

[0026] The hydraulic cylinder 310 is electrically connected to the control mechanism 500. It should be noted that in this embodiment, the control mechanism 500 is a lower-level machine, specifically a PLC. In another embodiment, the control mechanism 500 is a microcontroller. In other embodiments, the control mechanism 500 includes a higher-level machine and a lower-level machine, which are electrically connected.

[0027] To increase the operational stability of the stamping mechanism 300, please also refer to... Figure 1 and Figure 2In one embodiment, the stamping mechanism 300 further includes two limiting slide rods 360, which are cylindrical in shape. In another embodiment, the limiting slide rods 360 are quadrangular prisms. The two limiting slide rods 360 are respectively disposed on both sides of the receiving platform 100 and perpendicularly connected to the receiving platform 100. Sliding grooves 301 are provided at both ends of the upper receiving plate 320, which are adapted to the limiting slide rods 360. Each limiting slide rod 360 is correspondingly inserted into the sliding groove 301 and slidably connected to the upper receiving plate 320. Further, a linear bearing 321 is provided in each sliding groove 301 of the upper receiving plate 320. The linear bearing 321 is adapted to the limiting slide rod 360, and each limiting slide rod 360 is correspondingly inserted into the linear bearing 321. In this way, the two limit slides 360 prevent the upper support plate 320 from shaking during longitudinal movement, thereby increasing the working stability of the stamping mechanism 300.

[0028] To increase the operational stability of the fixing mechanism 400, in one embodiment, the rotating handle 440 and the rotating rod 430 are integrally formed, thereby increasing the structural strength and stability of the fixing mechanism 400. The rotating handle 440 is provided with anti-slip texture to increase its anti-slip performance, thus increasing the friction between the rotating handle 440 and the hand. In another embodiment, the rotating handle 440 is provided with an anti-slip pad, which increases the anti-slip performance of the rotating handle 440 while also protecting the hand. The anti-slip pad is a soft rubber pad, which has a certain degree of elasticity, good toughness, and excellent anti-slip performance. In another embodiment, the anti-slip pad is a soft silicone pad. This increases the operational stability of the fixing mechanism 400.

[0029] During operation, the aforementioned automotive battery connector stamping device 10 places the sheet metal to be stamped onto the lower stamping die 350. Both ends of the sheet metal protrude from the lower stamping die 350. The rotating handle 440 rotates the rotating rod 430, causing it to move closer to the sheet metal. This movement, along with the rotating plate 451 and rotating column 452, drives the limiting plate 453 to move closer to the sheet metal. Two fixing mechanisms 400 work together to limit the position of the sheet metal. The hydraulic cylinder 310, via the upper receiving plate 320, drives the upper stamping die 330 closer to the lower stamping die 350 to perform the stamping process. During the stamping process, the automotive battery connector stamping device 10 fixes the position of the sheet metal, increasing the stability of the stamping process and improving the production yield of automotive battery connectors.

[0030] To enhance the safety performance of the stamping mechanism 300, please refer to one embodiment as well. Figure 1 and Figure 2The stamping mechanism 300 also includes an industrial camera 370, which is connected to the side of the connecting table 200 facing the lower stamping die 350. The industrial camera 370 is electrically connected to the control mechanism 500. The industrial camera 370 can capture images of the space above the lower stamping die 350. When a foreign object is detected in the space above the lower stamping die 350, the control mechanism 500 controls the hydraulic cylinder 310 to stop working to avoid a safety accident. In this way, the industrial camera 370 increases the safety performance of the stamping mechanism 300.

[0031] To avoid placing two stacked sheet metal pieces onto the lower stamping die 350 during the feeding process, please refer to the following: Figure 1 , Figure 2 and Figure 4 In one embodiment, the automotive battery connector stamping device 10 further includes a double-sheet detection mechanism 600. The double-sheet detection mechanism 600 is mounted on the receiving platform 100. The double-sheet detection mechanism 600 includes a vertical connecting plate 610, a lead screw motor 620, a drive cylinder 630, an L-shaped connecting plate 640, and a contact-type single-probe metal double-sheet detector 650. The vertical connecting plate 610 is vertically connected to the receiving platform 100. The lead screw motor 620 is connected to the vertical connecting plate 610 and is driven by the drive cylinder 630. The drive cylinder 630 drives the contact-type single-probe metal double-sheet detector 650 to move closer to or further away from the lower stamping die 350 via the L-shaped connecting plate 640. When the sheet metal to be stamped is placed on the lower stamping die 350, the lead screw motor 620 and the drive cylinder 630 work in coordination to drive the contact-type single-probe metal double-sheet detector 650 to abut against the sheet metal to be stamped, performing double-sheet detection on the sheet metal. The lead screw motor 620, drive cylinder 630, and contact-type single-probe metal double-sheet detector 650 are all electrically connected to the control mechanism 500. The control mechanism 500 controls the lead screw motor 620, drive cylinder 630, contact-type single-probe metal double-sheet detector 650, and hydraulic cylinder 310 to work in a coordinated manner, thereby increasing the working stability of the automotive battery connector stamping device 10 and preventing two stacked sheets to be stamped from being placed on the lower stamping die 350 during the feeding process.

[0032] To prevent the stamped sheet metal from sticking to the upper stamping die 330 after the stamping mechanism 300 has stamped it, please refer to the following: Figure 2 and Figure 4The automotive battery connector stamping device 10 also includes an anti-sticking mechanism 700, which includes a blower 710, a blower hose 720, and several anti-sticking components 730. The blower 710 is mounted on the receiving platform 100, and its output end is connected to the input end of the blower hose 720. Each anti-sticking component 730 is evenly distributed on the upper stamping die 330. The upper stamping die 330 has several sliding tracks 302 on its side facing the lower stamping die 350, and a sliding cavity 303 is provided in the middle area of ​​each sliding track 302. A venting channel 304 is provided inside the upper stamping die 330, and each sliding track 302 is connected to the venting channel 304. Each anti-sticking component 730 includes a sliding tube 731, a sliding disc 732, and a compression spring 733. The sliding disc 732 is located in the middle area of ​​the sliding tube 731. The sliding disc 732 is adapted to the sliding cavity 303, and is inserted into the sliding cavity 303 and slidably connected to the upper stamping die 330. The sliding tube 731 is adapted to the sliding track 302, and is inserted into the sliding track 302 and slidably connected to the upper stamping die 330. The compression spring 733 is adapted to the sliding cavity 303, with one end of the compression spring 733 connected to one end of the sliding cavity 303 and the other end connected to the sliding disc 732. During the stamping process of the stamping mechanism 300, after the sliding tube 731 comes into contact with the sheet metal to be stamped, it moves along the sliding track 302 and retracts into the sliding track 302. During this process, the sliding disc 732 moves along the sliding cavity 303 and compresses the compression spring 733. After the stamping mechanism 300 has stamped the sheet metal, the compression spring 733 returns to its elastic deformation, driving the sliding tube 731, exposed outside the upper stamping die 330, via the sliding disc 732 to remove the sheet metal adhered to the upper stamping die 330. Simultaneously, the blower 710 introduces air into the ventilation channels 304 through the blower hose 720. The air is guided into each ventilation channel 304 and discharged through the sliding tube 731, further facilitating the removal of the sheet metal adhered to the upper stamping die 330. On the other hand, it also discharges hot air from the ventilation channels 304, cooling the upper stamping die 330. Thus, the anti-sticking mechanism 700 prevents the stamped sheet metal from sticking to the upper stamping die 330 after the stamping mechanism 300 has stamped the sheet metal. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
