Description

Technical Field

[0002] Electric vehicle film capacitors are an electronic component used in electric vehicles (especially the drive system and energy recovery system of new energy vehicles). They use organic films (such as polypropylene, polyester, etc.) as the medium and metallized film layers as electrodes, and are made by winding and packaging. They have the characteristics of high voltage resistance, low loss, high ripple current tolerance, and long life. They are mainly used for DC support, filtering, energy storage and release, etc., and are one of the key components to ensure the stable operation of electric vehicle power electronic systems.

[0003] Synchronous double-sided electrode attachment is a key process in the production of film capacitors. By spraying a metal layer on both end surfaces of the film, electrode lead-out terminals are formed to ensure electrode conductivity and consistency. In the existing technology, since a single film capacitor core is relatively small, it is difficult to achieve continuous and stable feeding during the electrode attachment process, which will cause the electrode attachment position to shift or tilt, resulting in overlapping, vacancies, uneven thickness, edge leakage or over-spraying of the metal layer on the end surface of the film, affecting the electrode conductivity and lead-out effect, and reducing the qualified rate.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] In this embodiment, when in use, the electric vehicle film capacitor core that needs to be attached to the electrode is first placed in the placement frame 104, and then the placement frame 104 filled with the film capacitor core is placed vertically so that it is placed in the slide 103. Then, the placement frame 104 can be controlled to move. When it moves to the bottom of the threaded barrel 405, the threaded rod 402 rotates. While the threaded rod 402 is rotating, since the threaded barrel 405 does not have any limit, the threaded barrel 405 can be driven to rotate by the threaded rod 402. At this time, the hook assembly on the threaded barrel 405 rotates synchronously, so that the hook assembly can be used to complete the connection with the handle 105 on the placement frame 104. At this time, the threaded barrel 405 produces a limit. Under the effect of the threaded connection, the threaded barrel 405 can be moved along the threaded rod 402. After the placement frame 104 is moved to the top of the spraying table 6, the electrode attachment operation of the film capacitor core can be realized by controlling the up and down reciprocating movement of the spraying part 608 and the spray gun 609. The provided material pipe 610 can realize the material transportation.

[0024] It should be noted that spray parts 608 and spray guns 609 are provided on both sides of the placement frame 104, which can achieve the effect of double-sided electrode attachment and enhance the spraying effect. In this application, the overall processing effect of the film capacitor core is improved by realizing orderly conveying and feeding of materials; the spray gun 609 can send the pure aluminum wire with positive and negative electrodes to a fixed position through the material pipe 610 for instant short circuit and melting, and then blow it to the two end faces of the capacitor core through negative ion high-pressure air. When it is cold, it solidifies into a metal dielectric layer. Each end face is sprayed four times with different particle sizes by four spray guns to make the metal dielectric layer reach a certain thickness, thereby realizing the function of synchronously attaching electrodes to the two end faces of the capacitor core.

[0029] In this embodiment, after the placement frame 104 is placed in the slide 103, the control screw 202 is rotated. It should be noted here that an output motor (not shown in the figure) is provided on the outer wall of the fixed block 2, which is used to control the rotation of the screw 202. When the screw 202 rotates, it will drive the T-block 203 to move, thereby driving the pull plate 204 connected to the T-block 203 to move, and then driving the dial plate 205 to move. The dial plate 205 corresponds to the position of the placement frame 104, so it can pull the placement frame 104 to move, and under the action of the slide column 106, it can improve the movement effect, reduce friction, and facilitate use.

[0030] When the first gear 305 is in the unlocking state, the second gear 306 is locked and the second gear 306 is unlocked, so that the second gear 306 is locked and the second gear 306 is unlocked.

[0031] When the dial plate 205 drives the placement frame 104 to move to the bottom of the threaded barrel 405, the pressure block 206 connected to the pull plate 204 will contact the pressure switch 209 on the vertical block 208, and the pressure block 206 will squeeze the pressure switch 209. The pressure switch 209 is connected to the output motor and the stepper motor 401 for signals. When the pressure switch 209 is squeezed, the output motor is turned off and the stepper motor 401 is started, thereby driving the threaded rod 402 to rotate.

[0033] Example 3: Reference Figures 1-13, a device for synchronously attaching electrodes on both sides of a film capacitor core, including a fixedly connected conveying platform 101 and a spraying platform 6, and also including a slide 103, fixedly connected to the conveying platform 101, a placement frame 104 is slidably connected in the slide 103, a film capacitor core is placed in the placement frame 104, a handle 105 is provided on the placement frame 104, a baffle 3 is fixedly connected to the conveying platform 101, and an opening is provided on the baffle 3; it also includes a threaded rod 402 rotatably arranged on the baffle 3 and an arc-shaped plate 403 fixedly arranged on the baffle 3, a threaded cylinder 405 is threadedly connected to the threaded rod 402, and a hook assembly is provided on the outer wall of the threaded cylinder 405, when the placement frame 104 moves to the bottom of the threaded cylinder 405, the threaded rod 402 rotates so that the hook assembly is engaged with the handle 105; a spraying part 608 is provided for reciprocating movement on the spraying platform 6, the spraying part 608 is provided with a spray gun 609, and the spraying part 608 is also provided with a material pipe 610.

[0034] The hook assembly includes a connecting block 409 fixedly connected to the outer wall of the threaded barrel 405, and the bottom of the connecting block 409 is fixedly connected to the hook plate 5 and the limit plate 502. The bottom of the hook plate 5 is provided with an arc section 501, and the limit plate 502 is rotatably connected to the locking plate 503 through a pin shaft. The limit plate 502 is also provided with a limit block 505 corresponding to the locking plate 503.

[0035] There are two threaded barrels 405 , a connecting rod 406 is fixedly connected between the two threaded barrels 405 , a first stopper 407 and a second stopper 408 are fixedly connected to the two threaded barrels 405 , and the first stopper 407 and the second stopper 408 are respectively arranged on both sides of the arc plate 403 .

[0036] Two vertical plates 601 are fixedly connected to the spraying table 6, and long grooves 604 are provided on both vertical plates 601. Support plates 602 are fixedly connected to both vertical plates 601, and corresponding sensors 603 are provided on the support plates 602. A fixed frame 605 is provided at the bottom of the spraying table 6, and a linear motor 606 is provided in the fixed frame 605. A moving platform 607 is provided at the output end of the linear motor 606, and a spraying part 608 is fixedly set on the moving platform 607.

[0037] It also includes a shell 1, the conveying platform 101 and the spraying platform 6 are fixedly connected in the shell 1, an L-plate 404 is fixedly connected to the outer wall of the shell 1, a stepper motor 401 is provided on the outer wall of the shell 1 away from the L-plate 404, a threaded rod 402 is arranged at the output end of the stepper motor 401, and the other end of the threaded rod 402 is rotatably set on the L-plate 404.

[0038] In this embodiment, starting the stepper motor 401 can drive the threaded rod 402 at the output end to rotate. When the threaded rod 402 rotates, since the threaded barrel 405 is not restricted at this time, it will rotate along with the threaded rod 402, thereby rotating the hook assembly and connecting it with the handle 105 to transport the placement frame 104 to move onto the spraying table 6 for electrode attachment operation. When the hook assembly rotates, the handle 105 will first touch the locking plate 503 on the limit plate 502, thereby rotating the locking plate 503 inward. After the handle 105 moves to the inside of the hook plate 5 and is no longer in contact with the locking plate 503, the locking plate 503 can automatically reset under the action of gravity and be in a vertical state again. At this state, the lock The tightening plate 503 can limit the handle 105 and prevent the locking plate 503 from falling out, and the set limit block 505 can block the locking plate 503 from rotating outward, so that the handle 105 will not fall off from the hook plate 5 at this time. The arc segment 501 set on the hook plate 5 can create a certain buffer space for the handle 105 when moving, making it more convenient to move. Secondly, in special usage occasions, a torsion spring 504 can be provided on the pin shaft, and the two ends of the torsion spring 504 are respectively connected to the pin shaft and the limit plate 502, so as to assist the locking plate 503 to rebound after the locking plate 503 rotates. In normal use, the torsion spring 504 is not needed, and the locking plate 503 can be reset by gravity alone.

[0039] When the hook assembly is connected to the handle 105, the first stopper 407 will rotate synchronously with the threaded barrel 405 until it abuts against the outer wall of the arc plate 403. At this time, the arc plate 403 will form a limit for the first stopper 407, so that the threaded barrel 405 cannot be rotated again. Therefore, under the action of the threaded connection, the threaded barrel 405 will move on the threaded rod 402, so that the hook assembly drives the placement frame 104 to move. When the threaded barrel 405 moves to the position of the sensor 603, the sensor 603 will detect the threaded barrel 405 and send a signal, so that the stepping motor 401 is turned off and the linear motor 606 is started at the same time. When the stepping motor 401 is turned off, the placement frame 104 can be placed between the two vertical Between the plates 601, the position of the film capacitor core in the frame 104 can correspond to the position of the long slot 604. After the linear motor 606 is started, it will drive the moving platform 607 at the output end to start working, thereby further moving the spray part 608 and the spray gun 609 to spray, and the movement mode of the linear motor 606 is a reciprocating linear motion up and down, which can enable the spray gun 609 to perform reciprocating spraying, making the spraying more uniform. The material pipe 610 is connected to the spray gun 609, and the other end passes through the shell 1 to be connected to the external material tank, which can facilitate feeding, and a telescopic tube for protecting the linear motor 606 is also provided between the moving platform 607 and the spraying platform 6 to prevent residual materials or dust during spraying from affecting the normal use of the linear motor 606.

[0040] A protective tube 4 is further provided on the outer wall of the housing 1 , which wraps around the outer wall of the stepper motor 401 , thereby protecting the stepper motor 401 and preventing workers from touching the stepper motor 401 during work.

[0041] The shell 1 is provided with a discharge port 107, the bottom of the conveying platform 101 is provided with a support leg 102, and the fixed block 2 is also provided with a groove 210, a convex plate 211 is slidably connected in the groove 210, a clamping block 212 is provided on the convex plate 211, and a slope is provided on the clamping block 212. An elastic member 213 is provided between the convex plate 211 and the inner wall of the groove 210.

[0042] In this embodiment, after spraying is completed, the stepper motor 401 is started, which can move the placement frame 104 out of the discharge port 107 on the shell 1, and then the worker can take it off, and then control the stepper motor 401 to reverse. At this time, the threaded barrel 405 located on the threaded rod 402 will first rotate with the threaded rod 402 when reversing. When the second stop block 408 and the other side of the arc plate 403 are lateral, the threaded barrel 405 will be limited again, and then move in the opposite direction under the action of the threaded connection, thereby completing the reset operation. At this time, the next material conveying work can be carried out, and the support leg 102 provided can support the end of the conveying platform 101 extending out of the shell 1.

[0043] When the pressure block 206 moves to cooperate with the pressure switch 209, the provided block 212 can also block the placement frame 104 and limit the placement frame 104 to a certain extent. When the threaded rod 402 drives the placement frame 104 to move, the placement frame 104 will generate a large moving force, thereby squeezing the smooth inclined surface on the block 212, so that the block 212 moves into the groove 210, allowing the placement frame 104 to pass through easily. Under the action of the elastic member 213, the block 212 can be automatically reset, which is convenient for repeated use. The elastic member 213 can specifically be a spring or a spring.
