Description

Technical Field

[0001] The present invention relates to the technical field of capacitor jigs, and particularly to a jig device for processing metallized film capacitors. Background Art

[0002] In the manufacturing process of metallized film capacitors, the jig device plays a crucial role. This device is not only used to fix the capacitor body but also often participates in the processing of capacitor pins, especially the pin bending process. Traditional capacitor processing jigs have various deficiencies, such as low automation, low processing efficiency, insufficient fixation of the capacitor body, and insufficient pin bending accuracy. Traditional processing methods often rely on manual operation, which not only increases labor costs but is also easily affected by human factors, resulting in unstable processing quality. Especially when bending capacitor pins, it is very difficult to ensure that the bending angles and positions of each capacitor pin are exactly the same by hand, which seriously affects the electrical performance and overall quality of the capacitor.

At the same time, when the capacitor body is processed by using the bending plate and the roller, the sliding frame can be straightened to ensure that the pressing piece accurately presses the capacitor body when the capacitor body is processed.

[0020] 3. By setting the support platform to be frustum-shaped, when the capacitor body needs to be discharged after processing, after the second spring returns to its initial state, the height of the outer wall of the top of the support platform is higher than the height of the outer wall of the top of the contact plate, ensuring that when the capacitor body is discharged after the sliding frame, the contact plate is prevented from blocking the capacitor body and causing the capacitor body to be unable to be discharged smoothly.

[0021] 4. Using the pneumatic method to realize the feeding of the capacitor body, so that a set of electric telescopic rods can be used to realize the feeding, bending processing and discharging of the capacitor body, which not only reduces the energy consumption during the processing, but also effectively reduces the occupied space of the device.

[0022] 5. By placing multiple capacitor bodies in the placing frame in a stacked manner and using the limiting frame to limit the capacitor bodies, it is ensured that the capacitor bodies do not displace during feeding, making the capacitor bodies more accurate during processing and reducing the defective rate.

[0035] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0036] Embodiment 1:

[0037] A fixture device for processing a metallized film capacitor, as Figures 1 to 8 shown, includes a base 1. A vertical plate 16 is fixed to the outer wall of the top of the base 1 by bolts. A placement frame 2 for placing the capacitor body 11 is welded between the two vertical plates 16. An extension plate 8 is fixed to the outer wall of one side of the placement frame 2 by bolts. An electric telescopic rod 3 is fixed to the outer wall of the top of the extension plate 8 by bolts. The output end of the electric telescopic rod 3 is fixed to an intermediate plate 12 by a pin. A pressing rod member is fixed to the bottom of the intermediate plate 12. A lining plate 22 is fixed to the outer wall of the top of the base 1 by bolts. An elastic rotating mechanism is rotatably connected between the two lining plates 22. A sliding frame 24 is fixed to the top of the rotating mechanism. A resisting plate 26 is welded to the inner walls on both sides of the sliding frame 24. An elastic plate member for supporting the capacitor body 11 is installed on the inner wall of the bottom of the sliding frame 24. Pressing plates 15 are welded to the outer walls on both sides of the sliding frame 24. An elastic rod member is fixed to the outer wall of the bottom of the intermediate plate 12. A backing plate 6 is fixed to the bottom of the elastic rod member. A bending plate 38 is fixed to one end of the backing plate 6. A roller 13 that cooperates with the pressing plate 15 is rotatably connected to the inner wall of the bending plate 38;

[0038] By providing a placement frame 2, the capacitor bodies 11 that need to be processed can be stacked, which is convenient for subsequent sequential processing of multiple capacitor bodies 11. When the capacitor body 11 needs to be processed, the capacitor body 11 can be supported by an elastic plate. At the same time, the sliding frame 24 and the contact plate 26 limit the capacitor body 11 to avoid lateral displacement of the capacitor body 11, thereby ensuring the accuracy after subsequent processing. During processing, the electric telescopic rod 3 is used to synchronously drive the elastic rod and the pressure rod to move downward. In the initial stage, the height of the roller 13 is lower than the height of the bottom of the pressure rod. The roller 13 gradually approaches the pressure plate 15 during the downward movement. In the initial stage, the elastic rotating mechanism and the horizontal plane are inclined at a certain angle. As the roller 13 gradually moves toward the pressure plate 15, when the roller 13 and the upper surface of the pressure plate 15 are in contact with each other, the roller 13 The pressure plate 15 is pressed, and after being pressed, the pressure plate 15 gradually changes from an inclined state to a vertical state. During this process, the sliding frame 24 moves synchronously with the pressure plate 15, so that the sliding frame 24 rotates to be perpendicular to the horizontal plane. At this time, as the electric telescopic rod 3 continues to drive the elastic rod and the pressure rod to move downward, the elastic rod gradually produces elastic deformation, and the pressure rod presses the capacitor body 11 on the elastic plate under the drive of the electric telescopic rod 3, thereby clamping and fixing the capacitor body 11. As the pressure rod continues to move downward, the capacitor body 11 gradually moves toward the side wall of the bending plate 38. When the pins of the capacitor body 11 contact the side of the bending plate 38, the bending plate 38 is used to limit the pins of the capacitor body 11, so that the pins of the capacitor body 11 are bent during the movement, thereby realizing the bending processing of the pins of the capacitor body 11.

[0039] The pressure rod member includes a vertical rod 32 and a pressure plate 33. The vertical rod 32 is fixed to the bottom outer wall of the middle plate 12 by bolts, and the pressure plate 33 is welded to the bottom outer wall of the vertical rod 32.

[0040] The capacitor body 11 on the elastic plate can be pressed by providing the pressing sheet 33 , and the capacitor body 11 moves downward along the sliding frame 24 after being pressed.

[0041] The elastic plate includes a support platform 25 and a second spring 28, the bottom of the second spring 28 is clamped to the bottom inner wall of the sliding frame 24, and the support platform 25 is slidably connected to the inner wall of the sliding frame 24, and the top of the second spring 28 and the bottom of the support platform 25 are clamped and fixed;

[0042] In this embodiment, the support platform 25 is a prism-shaped support platform 25, which is used to support the capacitor body 11 that needs to be bent. When the middle plate 12 is pressed against the top of the capacitor body 11, the deformation of the spring 28 is used to allow the capacitor body 11 to move up and down along the sliding frame 24.

[0043] The elastic rod member includes a first air cylinder 7 and a second piston rod 34. The first air cylinder 7 is fixed to the outer wall of the bottom of the middle plate 12 by screws. The second piston rod 34 is slidably connected to the inner wall of the through hole formed at the bottom of the first air cylinder 7. A second piston plate 31 is fixed to the top of the second piston rod 34. A third spring 35 is clamped between the top of the second piston plate 31 and the inner wall of the top of the first air cylinder 7. The bottom of the second piston rod 34 is fixedly connected to the top of the cushion plate 6.

[0044] When the roller 13 presses the pressing plate 15 during the downward movement, as the electric telescopic rod 3 drives the vertical rod 32 and the pressing piece 33 to move downward to press the capacitor body 11 on the top of the support table 25, the elastic deformation of the third spring 35 enables the first air cylinder 7 to slide relative to the second piston rod 34, so as to ensure that the pressing piece 33 bends the capacitor body 11 after pressing and then uses the bending plate 38 for bending.

[0045] The elastic rotating mechanism includes a lining plate 22 and a limiting piece 21. Both lining plates 22 are welded to the outer wall of the top of the base 1, and the limiting piece 21 is welded to the outer wall of one side of the two lining plates 22. A rotating shaft 39 is rotatably connected to the through holes formed in the side walls of the two lining plates 22. A rotating block 27 is fixed to the outer circumference of the rotating shaft 39 by a pin. The top of the rotating block 27 is fixedly welded to the bottom of the sliding frame 24. A torsion spring 14 is clamped between the outer circumference of the rotating shaft 39 and one side of one of the lining plates 22.

[0046] In the initial stage, the torsion of the torsion spring 14 makes the sliding frame 24 incline at a certain angle with the horizontal plane. When the roller 13 moves down to the surface of the pressing plate 15 and presses the roller 13, the sliding frame 24 gradually rotates from the inclined state to the vertical state. The limiting piece 21 limits the maximum rotation angle of the sliding frame 24. The bottom of the rotating block 27 is of an arc structure to prevent the rotating block 27 from getting stuck during rotation.

[0047] When the pins of the capacitor body 11 are bent and the roller 13 disengages from the pressing plate 15, at this time, the sliding frame 24 is driven by the restoring force of the torsion spring 14 to incline again. The purpose is to make the processed capacitor body 11 slide down along the support table 25 under its own gravity, realizing the blanking of the processed capacitor body 11.

[0048] In this embodiment, the elastic coefficient of the third spring 35 is greater than that of the torsion spring 14, that is, when the roller 13 presses the pressing plate 15 during the downward movement, the deformation degree of the third spring 35 is lower than that of the torsion spring 14. Thus, it is ensured that the torsion spring 14 first deforms to make the sliding frame 24 change from the inclined state to the vertical state, and then the third spring 35 deforms to a greater extent under the drive of the electric telescopic rod 3 after the roller 13 is limited by the pressing plate 15.

[0049] When this embodiment is in use, the capacitor body 11 to be processed is stacked in the placement frame 2. The capacitor body 11 is preliminarily positioned in the placement frame 2. Subsequently, driven by the electric telescopic rod 3, the middle plate 12 and the pressing rod and elastic rod below it start to move downward. In the initial stage, the height of the roller 13 is lower than the height of the bottom of the pressing rod. As the roller 13 moves downward, it gradually approaches the pressing plate 15. The torsion spring 14 in the elastic rotation mechanism keeps a certain inclination angle between the sliding frame 24 and the horizontal plane in the initial stage. When the roller 13 fits on the upper surface of the pressing plate 15, the roller 13 exerts pressure on the pressing plate 15, causing the pressing plate 15 and the sliding frame 24 connected to it to start changing from the inclined state to the vertical state. The sliding frame 24 and the capacitor body 11 inside it are limited, avoiding lateral displacement and ensuring the processing accuracy. As the electric telescopic rod 3 continues to drive, the elastic rod slides relative to the air cylinder 1 7 under the action of the spring three 35. At the same time, the pressing rod presses the capacitor body 11 on the elastic plate. After the capacitor body 11 is pressed, it moves downward along the sliding frame 24 until its pins contact the side surface of the bending plate 38. The bending plate 38 limits the pins of the capacitor body 11 and bends them. After the pins of the capacitor body 11 are bent, the electric telescopic rod 3 retracts, and the roller 13 disengages from the pressing plate 15. The sliding frame 24 tilts again under the action of the resilience of the torsion spring 14. This tilt causes the processed capacitor body 11 to slide down along the support table 25 under its own gravity, realizing the blanking of the processed capacitor body.

[0050] Embodiment 2:

[0051] A fixture device for processing metallized film capacitors, as Figures 1 to 8 shown. To facilitate the automatic feeding of the capacitor body 11; the following supplements are made to this embodiment on the basis of Embodiment 1: An embedding plate 20 is welded between the two vertical plates 16. A through hole opened on the surface of the embedding plate 20 embeds an air cylinder 2 36. A piston rod 1 19 is slidably connected to a through hole opened at one end of the air cylinder 2 36. A piston plate 1 23 is fixed to one end of the piston rod 1 19. A spring 1 17 is clamped between the outer wall of one side of the piston plate 1 23 and the inner wall of one side of the air cylinder 2 36. A push plate 9 is fixed to the top of the piston rod 1 19. An insertion plate 37 is fixed to one end of the push plate 9. A sponge layer 40 is bonded to the bottom of the insertion plate 37. A jack adapted to the outer diameter of the push plate 9 is opened on the side wall of the placement frame 2;

[0052] After one of the capacitor bodies 11 is processed, in order to facilitate the processing of the remaining capacitor bodies 11 stacked in the placement frame 2, at the initial stage, the push plate 9 and the insertion plate 37 are located outside the placement frame 2. When it is necessary to load the capacitor bodies 11 in the placement frame 2, by pushing the piston rod one 19 along the air cylinder two 36, the push plate 9 and the insertion plate 37 push the lowermost capacitor body 11 after being inserted into the insertion holes. After being pushed, the capacitor body 11 moves towards the support table 25. At the initial stage, the height of the outer wall at the top of the support table 25 is higher than the height of the bottom of the capacitor body 11, so that when the capacitor body 11 is pushed above the support table 25, it first squeezes the inclined surface of the support table 25. During this process, the spring two 28 is compressed downward by a certain length. When the end of the capacitor body 11 abuts against the abutting plate 26, since the abutting plate 26 limits the capacitor body 11, the push plate 9 and the insertion plate 37 cannot continue to push the capacitor body 11, thereby limiting the position of the capacitor body 11 in the horizontal direction to ensure that the subsequent pressing piece 33 accurately presses down on the capacitor body 11. The insertion plate 37 can limit the capacitor body 11 in the longitudinal direction, and the sponge layer 40 protects the capacitor body 11 when it is pushed.

[0053] By setting the support table 25 as a frustum shape, when it is necessary to unload the capacitor body 11 after processing, after the spring two 28 returns to its initial state, the height of the outer wall at the top of the support table 25 is higher than the height of the outer wall at the top of the abutting plate 26, so as to ensure that when the capacitor body 11 slides out of the sliding frame 24 for unloading, the abutting plate 26 does not block the capacitor body 11 and cause the capacitor body 11 to be unable to be unloaded smoothly.

[0054] A limiting frame 10 is welded to the outer wall of one side of the extension plate 8;

[0055] By providing the limiting frame 10, the stacked multiple capacitor bodies 11 can be limited in the horizontal direction. A gap equal to the thickness of the push plate 9 is reserved between the bottom of the limiting frame 10 and the inner wall of the top of the placement frame 2, so as to ensure that only one capacitor body 11 is pushed by the push plate 9 and the insertion plate 37 when the capacitor body 11 needs to be loaded.

[0056] An air hole one is opened at the top of the air cylinder one 7, an air hole two is opened on the side wall of the air cylinder two 36, and the top of the air cylinder one 7 and the side wall of the air cylinder two 36 are connected by a hose 18. A waist-shaped hole 29 is opened on the side wall of the air cylinder one 7, and a sealing plate 4 is fixed to the outer circumference of the piston rod two 34 by screws, and a moving hole 5 matching the waist-shaped hole 29 is opened on the side wall of the sealing plate 4. A one-way valve 30 is threadedly connected to the side wall of the air cylinder one 7;

[0057] For the convenience of automatically loading the capacitor body 11, at the initial stage, after the roller 13 and the pressing plate 15 are in surface contact to straighten the sliding frame 24, as the electric telescopic rod 3 continues to drive the pressing piece 33 downward, the air cylinder 7 moves downward relative to the piston rod 34, causing the piston plate 31 to move towards the inner wall of the top of the air cylinder 7. During this process, the piston plate 31 squeezes the air in the chamber between it and the inner wall of the top of the air cylinder 7. The squeezed air enters the air cylinder 36 through the hose 18. The air entering the air cylinder 36 pushes the piston plate 23, causing the piston plate 23 and the piston rod 19 to drive the push plate 9 and the insertion plate 37 to move into the insertion holes on the placement frame 2. Furthermore, during the movement of the push plate 9 and the insertion plate 37, the capacitor body 11 is pushed. After being pushed, the capacitor body 11 moves to the top of the support table 25. As the air cylinder 7 continues to slide downward along the piston rod 34, a relative opening degree gradually occurs between the waist-shaped hole 29 and the moving hole 5. At this time, the air pressure inside and outside the air cylinder 7 is balanced, causing the piston rod 19 and the piston plate 23 to drive the push plate 9 and the insertion plate 37 to reset under the resilience of the spring 17. After the push plate 9 and the insertion plate 37 are reset, it is convenient to push and load the unprocessed capacitor body 11 again later. A rubber pad is fixed on the inner surface of the sealing plate 4 to ensure the sealing performance between it and the circumferential outer wall of the air cylinder 7. When the air cylinder 7 needs to reset relative to the piston rod 34, when the piston plate 31 moves away from the inner wall of the top of the air cylinder 7, negative pressure is used to suck the outside air into the chamber between the piston plate 31 and the inner wall of the top of the air cylinder 7 through the one-way valve 30, thereby realizing the processing and loading of the capacitor body 11 by means of pneumatic drive.

[0058] In the use of this embodiment, in the initial state, the waist-shaped hole 29 and the moving hole 5 are relatively closed to maintain the air pressure in the first air cylinder 7. When it is necessary to load the capacitor body 11 in the placement frame 2, the electric telescopic rod 3 drives the pressing piece 33 to move downward. During the downward movement of the pressing piece 33, the sliding frame 24 is straightened and continues to move downward through the roller 13 and the pressing plate 15. As the pressing piece 33 and the electric telescopic rod 3 continue to move downward, the first air cylinder 7 moves downward relative to the second piston rod 34, and the piston plate 31 squeezes the air between the top of the first air cylinder 7 and the piston plate 31. The squeezed air enters the second air cylinder 36 through the hose 18, pushing the piston plate 23 and the first piston rod 19 to move towards the placement frame 2. The first piston rod 19 drives the push plate 9 and the insertion plate 37 to insert into the insertion hole of the placement frame 2 to push the lowermost capacitor body 11. The capacitor body 11 is pushed towards the support platform 25, first squeezing the inclined surface of the support platform 25, compressing the second spring 28. The capacitor body 11 moves to the contact plate 26 and is limited. The push plate 9 and the insertion plate 37 stop pushing. As the first air cylinder 7 continues to slide downward along the second piston rod 34, the relative opening between the waist-shaped hole 29 and the moving hole 5 increases, and the internal and external air pressures of the first air cylinder 7 are balanced. Under the resilience of the first spring 17, the first piston rod 19 and the piston plate 23 drive the push plate 9 and the insertion plate 37 to reset outside the placement frame 2. When the first air cylinder 7 needs to reset relative to the second piston rod 34, when the piston plate 31 moves away from the inner wall of the top of the first air cylinder 7, it inhales external air through the one-way valve 30 into the chamber between the piston plate 31 and the top of the first air cylinder 7 to prepare for the next loading. After the capacitor body 11 is processed, the second spring 28 returns to the initial state, and the height of the outer wall of the top of the support platform 25 is higher than that of the contact plate 26, ensuring that the capacitor body 11 can smoothly slide out from the rear of the sliding frame 24 and avoiding the blockage of the contact plate 26.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
