Abstract
Description
Technical Field
[0001] This utility model relates to the field of varistor production equipment, specifically to a varistor assembly cover plate and foot assembly device. Background Technology
[0002] In the manufacturing process of varistors, after quartz sand is added to the resistor's housing, a cover plate needs to be assembled onto the housing to seal it. The existing method of assembling the cover plate is done manually by holding the cover plate onto the housing. This manual assembly method is very slow and may result in some cover plates not being pressed into place, requiring rework. This method is costly and cannot meet the needs of automated production. Utility Model Content
[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a varistor assembly cover plate and a lead-aligning device, the specific technical solution of which is as follows:
[0004] A varistor assembly cover and pin-aligning device includes a material transfer track plate, a product transfer mechanism, a pin alignment mechanism, a cover plate pin insertion mechanism, a cover plate initial pressing mechanism, a cover plate secondary pressing mechanism, a pin secondary shaping mechanism, and a positioning mechanism. Two spaced-apart material transfer tracks are used. The varistor enters between the two tracks. The material transfer tracks extend from left to right. The product transfer mechanism drives the varistor to move from left to right, sequentially passing through the pin alignment mechanism, the cover plate pin insertion mechanism, the cover plate initial pressing mechanism, the cover plate secondary pressing mechanism, and the pin secondary shaping mechanism. The cover plate initial pressing mechanism, the cover plate secondary pressing mechanism, and the pin secondary shaping mechanism are all installed on the lifting plate. The pin alignment mechanism aligns and shapes the varistor pins to ensure subsequent cover plate insertion. The cover plate pin insertion mechanism drives the cover plate to insert into the varistor pins. The cover plate initial pressing mechanism drives the cover plate to initially press into the varistor housing. The cover plate secondary pressing mechanism drives the cover plate to press into place. The pin secondary shaping mechanism shapes the varistor pins after the cover plate is assembled. The positioning mechanism is located in front of the material transfer track plate and fixes the position of the varistor entering different workstations.
[0005] As a preferred embodiment of this utility model, the pin alignment mechanism includes left and right alignment components and front and rear alignment components. The left and right alignment components include a first lifting cylinder, left and right alignment cylinders, and alignment clamps. The first lifting cylinder drives the left and right alignment cylinders to lift and lower, and the left and right alignment cylinders drive the two alignment clamps to retract left and right so that the alignment grooves of the alignment clamps contact the varistor pins. The front and rear alignment components include a second cylinder, a rear positioning plate, and a front V-shaped clamp. The second cylinder drives the rear positioning plate to move forward, and the front V-shaped clamp is installed on the positioning mechanism. The forward movement of the rear positioning plate and the backward movement of the front V-shaped clamp cooperate to align the varistor pins.
[0006] As a preferred embodiment of this utility model, the cover plate insertion pin mechanism includes a vibratory feeder, a linear vibration track, a cover plate rotating cylinder, a cover plate moving module, a cover plate holding platform, and a cover plate clamping cylinder. The vibratory feeder drives the cover plates to enter the linear vibration track in an orderly manner. A linear vibrator is installed at the bottom of the linear vibration track. The linear vibration track and the cover plate holding platform approach the material transfer track plate from the rear in sequence. The cover plate rotating cylinder clamps the cover plate at the front end of the linear vibration track and rotates it 180° to change its position. The cover plate clamping cylinder clamps the cover plate in the cover plate holding platform and transfers it to insert the varistor pin. The cover plate rotating cylinder and the cover plate clamping cylinder are installed at the output end of the cover plate moving module. The cover plate moving module drives the cover plate rotating cylinder and the cover plate clamping cylinder to move back and forth and up and down.
[0007] As a preferred embodiment of this utility model, the initial pressing mechanism of the cover plate includes a first pressing cylinder, a vertical positioning strip for the material shell, and a U-shaped pressing block. When the pressure-sensitive resistor reaches the first pressing position of the cover plate, the vertical positioning strip for the material shell presses against the material shell, and the first pressing cylinder drives the U-shaped pressing block to extend into the cover plate. The secondary pressing mechanism of the cover plate includes a second pressing cylinder and a U-shaped pressing block. When the pressure-sensitive resistor reaches the secondary pressing position of the cover plate, the second pressing cylinder drives the U-shaped pressing block to extend into the cover plate.
[0008] As a preferred embodiment of this utility model, the pin secondary shaping mechanism includes a shaping cylinder, a wedge block, and an opening and closing clamp. The shaping cylinder drives the wedge block to move up and down, and the wedge block drives the opening and closing clamp to open and close, thereby clamping the lead wire.
[0009] As a preferred embodiment of this utility model, the positioning mechanism includes a swing rod, a connecting rod, a front and rear moving plates, and a positioning plate. A cam mechanism drives the swing rod to swing. The connecting rod is connected above the swing rod, and the front and rear moving plates are connected behind the connecting rod. The front and rear moving plates are located in front of the material transfer track plate. Multiple positioning plates are installed above the front and rear moving plates. The positioning plates are provided with positioning grooves, and the openings of the positioning grooves are widened.
[0010] Beneficial effects: When the varistor assembly cover plate and pin-aligning device of this utility model is working, the product moving mechanism drives the varistor to move from left to right, passing through the pin alignment mechanism, the cover plate pin insertion mechanism, the cover plate initial pressing mechanism, the cover plate secondary pressing mechanism, and the pin secondary shaping mechanism. The pin alignment mechanism aligns and shapes the varistor pins to ensure subsequent cover plate insertion. The cover plate pin insertion mechanism drives the cover plate to insert into the varistor pins. The cover plate initial pressing mechanism drives the cover plate to initially press into the varistor housing. The cover plate secondary pressing mechanism drives the cover plate to press into place. The pin secondary shaping mechanism shapes the varistor pins after the cover plate is assembled. This replaces manual operation, realizes automated cover plate assembly, has a fast production speed, and has high cover plate installation accuracy, reducing rework rate, which is conducive to improving product quality and reducing production costs.

[0020] like Figure 1 and 2As shown, a varistor assembly cover plate and pin-aligning device includes a material transfer track plate 1, a product transfer mechanism 2, a pin alignment mechanism 3, a cover plate pin insertion mechanism 4, a cover plate initial pressing mechanism 5, a cover plate secondary pressing mechanism 6, a pin secondary shaping mechanism 7, and a positioning mechanism 8. The material transfer track plate 1 consists of two spaced-apart pieces. The varistor 9 enters between the two moving track plates 1. The material transfer track plate 1 extends from left to right. The product transfer mechanism 2 drives the varistor 9 to move from left to right, sequentially passing through the pin alignment mechanism 3, the cover plate pin insertion mechanism 4, the cover plate initial pressing mechanism 5, the cover plate secondary pressing mechanism 6, and the pin secondary shaping mechanism 7 to achieve different processes. The product transfer mechanism 2 can be implemented using a chain drive mechanism, a conveyor belt drive mechanism, or a stepping mechanism. This is a mechanical... The specific structure is not described further as it is a conventional technology in the field and is not the focus of this invention. The cover plate initial pressing mechanism 5, the cover plate secondary pressing mechanism 6, and the pin secondary shaping mechanism 7 are all installed on the lifting plate 10. The lifting plate 10 can be driven by a cylinder, a hydraulic cylinder, or a cam transmission mechanism to move up and down. The pin guiding mechanism 3 guides and shapes the pins of the varistor to ensure the subsequent insertion of the cover plate. The cover plate pin insertion mechanism 4 drives the cover plate to insert into the pins of the varistor. The cover plate initial pressing mechanism 5 drives the cover plate to initially press into the varistor housing. The cover plate secondary pressing mechanism 6 drives the cover plate to press into place. The pin secondary shaping mechanism 7 shapes the pins of the varistor after the cover plate is assembled. The positioning mechanism 8 is located in front of the material transfer track plate 1. The positioning mechanism 8 fixes the position of the varistor entering different workstations.
[0021] like Figure 3 and 4 As shown, the pin alignment mechanism 3 includes left and right alignment components and front and rear alignment components. The left and right alignment components include a first lifting cylinder 31, left and right alignment cylinders 32, and alignment clamps 33. The first lifting cylinder 31 drives the left and right alignment cylinders 32 to rise and fall, and the left and right alignment cylinders 32 drive the two alignment clamps 33 to retract left and right so that the alignment grooves of the alignment clamps 33 contact the varistor pins. The front and rear alignment components include a second cylinder 34, a rear positioning plate 35, and a front V-shaped clamp 36. The second cylinder 34 drives the rear positioning plate 35 to move forward, and the front V-shaped clamp 36 is installed on the positioning mechanism 8. The forward movement of the rear positioning plate 35 and the backward movement of the front V-shaped clamp 36 cooperate to align the varistor pins. The varistor pins are first aligned from the left and right by the left and right alignment components, and then aligned from the front and rear by the front and rear alignment components, ensuring that the pins are straight for easy subsequent cover plate insertion.
[0022] like Figure 5As shown, the cover plate insertion pin mechanism 4 includes a vibratory feeder (not shown), a linear vibration track 42, a cover plate rotating cylinder 43, a cover plate moving module 44, a cover plate holding platform 45, and a cover plate clamping cylinder 46. The vibratory feeder drives the cover plates to enter the linear vibration track 42 in an orderly manner. A linear vibrator 47 is installed at the bottom of the linear vibration track 42. The linear vibrator 47 drives the cover plates entering the linear vibration track 42 to move forward. The linear vibration track 42 and the cover plate holding platform 45 approach the material transfer track plate 1 from the rear in sequence. The cover plate rotating cylinder 43 clamps the cover plate at the front end of the linear vibration track and rotates it 180° to change its position. The cover plate clamping cylinder clamps the cover plate in the cover plate holding platform and transfers it to insert the varistor pin. The cover plate rotating cylinder and the cover plate clamping cylinder are installed at the output end of the cover plate moving module. The cover plate moving module drives the cover plate rotating cylinder and the cover plate clamping cylinder to move back and forth and up and down.
[0023] like Figure 6 As shown, the initial pressing mechanism 5 of the cover plate includes a first pressing cylinder 51, a vertical positioning strip 52 for the material shell, and a U-shaped pressing block 53. When the varistor reaches the first pressing position, the vertical positioning strip 52 presses against the varistor material shell, and the first pressing cylinder 51 drives the U-shaped pressing block 53 to extend into the cover plate. The secondary pressing mechanism 6 of the cover plate includes a second pressing cylinder and a U-shaped pressing block 62. When the varistor reaches the secondary pressing position, the second pressing cylinder drives the U-shaped pressing block 62 to extend into the cover plate 1. The U-shaped pressing block 62 can avoid the two leads. In addition, the secondary shaping mechanism 7 of the leads includes a shaping cylinder 71, a wedge block 72, and an opening and closing clamp 73. The shaping cylinder drives the wedge block to move up and down, and the wedge block drives the opening and closing clamp to open and close, clamping the lead wire.
[0024] like Figure 2 As shown, the positioning mechanism 8 includes a swing rod 81, a connecting rod 82, a front and rear moving plate 83, and a positioning plate 84. The cam mechanism drives the swing rod 82 to swing. The connecting rod 82 is connected above the swing rod 81, and the front and rear moving plate 83 is connected behind the connecting rod 82. The front and rear moving plate 83 is located in front of the material transfer track plate 1. Multiple positioning plates 84 are installed above the front and rear moving plate 83. The positioning plate 84 is provided with a positioning groove, and the opening of the positioning groove is widened to facilitate the entry of the product.
[0025] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
