Description

Technical Field

[0001] This utility model belongs to the field of varistor manufacturing technology, and in particular relates to a cutting mechanism for varistor manufacturing. Background Technology

[0002] A varistor is a semiconductor device used for overvoltage protection. It is mainly used for overvoltage protection, acting to protect semiconductor devices and electrical surge overvoltage protection. Its resistance value changes non-linearly with the applied voltage. It has the characteristics of wide voltage operating range, large non-linear coefficient, large current capacity, strong protection capability, and fast response time. Varistors play a vital role in circuits and are widely used in various power supplies, charging piles, automobiles, home appliances, communications, aerospace, and power energy.

[0003] However, existing varistors are usually produced using tape and reel, which arranges multiple varistors on a continuous tape. These tapes are relatively long and are more prone to knotting or tangling during handling. This not only increases the difficulty of handling but may also damage the tape and affect product quality. To address this, we propose a cutting mechanism for varistor production. Utility Model Content

[0004] The purpose of this invention is to provide a cutting mechanism for the production of varistors. By setting up a cutting component, it solves the problem that existing varistors are usually produced using tape and reel, where multiple varistors are arranged on a continuous tape. These tapes are relatively long and are more prone to knotting or tangling during handling. This not only increases the difficulty of handling but may also damage the tape and affect product quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a cutting mechanism for producing varistors, comprising an auxiliary component. A cutting component is disposed on the right side of the auxiliary component. The cutting component includes a cutting component housing, and a cutting platform is disposed at the center of the cutting component housing. The front and back of the cutting platform are fixedly connected to the inner surface of the cutting component housing. A threaded screw is rotatably connected to the top of the cutting component housing. The top of the threaded screw penetrates the outer surface of the top of the cutting component housing and extends outward. The threaded screw is rotatably connected to the top of the cutting component housing. A second motor is fixedly connected to the center of the top of the cutting component housing. The output end of the second motor is on the same horizontal line as the threaded screw. The output end of the second motor is fixedly connected to the top of the threaded screw through a coupling. A cutting blade is threadedly connected to the outer surface of the threaded screw. The cutting blade is driven to move downward through the outer surface of the threaded screw, thereby cutting the long braid of the varistor placed on the cutting platform.

[0007] Furthermore, the auxiliary component includes an auxiliary component housing, inside which are arranged two rotating rods. The two rotating rods are arranged in a horizontal array around the auxiliary component housing. The front and back of the two rotating rods penetrate the outer surface of the auxiliary component housing and extend outward. Both rotating rods are rotatably connected to the auxiliary component housing. Rollers are fixedly connected to the outer surface of the two rotating rods. The dimensions of the recesses of the two rollers are adapted to the dimensions of the tape of the varistor. The rollers can be rotated by rotating the rotating rods. During the rotation, the rollers rub against the tape of the varistor through the grooves, causing the varistor to move to the right. The movement range of the tape is also restricted within the grooves of the rollers to prevent the tape varistor from shifting during movement.

[0008] Furthermore, pulleys are fixedly connected to the front of both rotating rods, and belts are fitted onto the outer surfaces of the two pulleys. The two pulleys are connected by belt drive. A rectangular fixing plate is fixedly connected to the front of the left side of the auxiliary component housing. A motor is fixedly connected to the top of the rectangular fixing plate. The output end of the back of the motor is at the same horizontal height as the pulley on the right side. The output end of the back of the motor is fixedly connected to the front of the pulley on the right side through a coupling. The output end of the motor can drive the pulley on the right side to rotate. When the pulley on the right side rotates, it will drive the pulley on the left side to rotate through the belt, so that the two pulleys can be synchronized and the two rotating rods fixedly connected to the rear can also rotate synchronously.

[0009] Furthermore, a downward sliding block is provided on one side of the two rotating rods that are close to each other. A sliding rod is fixedly connected to the top of the downward sliding block. The sliding rod extends outward through the center of the top of the auxiliary component housing and is slidably connected to the center of the top of the auxiliary component housing. A central protrusion is fixedly connected to the top of the sliding rod. A spring is sleeved on the outer surface of the sliding rod. The top of the spring is fixedly connected to the inner bottom surface of the auxiliary component housing, and the bottom of the spring is fixedly connected to the top of the downward sliding block. A conveyor belt is provided below the downward sliding block. The front and back of the conveyor belt are fixedly connected to the inner surface of the auxiliary component housing. By setting the downward sliding block, the varistor can be squeezed to prevent the varistor from shaking up and down during movement, thus ensuring the stability of the cutting component.

[0010] Furthermore, the threaded screw is provided with slide rods 2 on both the front and back sides. The top of the slide rods 2 is fixedly connected to the bottom inner surface of the cutting assembly housing. The bottom of the cutting assembly housing is fixedly connected to the top of the cutting platform. The cutting blade is provided with circular grooves on both the front and back sides. The inner surface of the circular grooves of the cutting blade is slidably connected to the outer surface of the slide rods 2. When the threaded screw drives the cutting blade to move up and down, the cutting blade will move up and down along the slide rods 2 through the circular grooves on the front and back sides, preventing the cutting blade from deflecting during movement.

[0011] Furthermore, irregular grooves are formed on both the front and back sides of the inner surface of the cutting component housing. The irregular grooves of the cutting component housing extend from the top inner wall of the cutting component housing to the top of the cutting platform. Irregular sliders are fixedly connected to both the front and back sides of the cutting blade. The irregular sliders of the cutting blade are adapted to the irregular grooves of the cutting component housing. The irregular sliders of the cutting blade and the irregular grooves of the cutting component housing are configured so that the cutting blade can move along the irregular grooves of the cutting component housing through the irregular sliders when moving up and down, further restricting the movement of the cutting blade and preventing the cutting blade from deflecting.

[0012] Furthermore, a rectangular slot is provided on the top of the cutting platform, and the tip of the cutting blade is inserted into the rectangular slot of the cutting platform. A triangular wedge is fixedly connected to the right side of the cutting platform. The front and back of the triangular wedge are fixedly connected to the inner surface of the cutting assembly housing. By setting the rectangular slot of the cutting platform, the cutting blade can move into the rectangular slot of the cutting platform to completely cut the long braid of the varistor. The setting of the triangular wedge allows the cut varistor to slide out of the equipment.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model sets up a cutting component, specifically starting a second motor. The output end of the second motor drives a threaded screw to rotate through a coupling. When the threaded screw rotates, it drives the cutting blade downward through the outer surface, cutting the tape of the varistor that is conveyed to the top of the cutting platform. This cuts a long tape into several small segments, preventing damage caused by knotting during the transportation of the tape varistor.

[0015] 2. This utility model incorporates an auxiliary component, specifically a starting motor. The motor drives a rotating rod via a pulley. As the rotating rod rotates, it moves the tape of the varistor to the right via the groove of a roller. The roller also restricts the movement of the tape varistor, preventing it from moving back and forth and failing to accurately reach the cutting component for cutting.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The roller 122 can limit the movement of the tape of the varistor, preventing the varistor from moving back and forth and failing to move accurately to the cutting component 2 for cutting.

[0028] Both rotating rods 121 are fixedly connected to pulleys 131 on their front sides. The outer surfaces of the two pulleys 131 are fitted with belts 132.

[0034] Next, the conveyor belt 17 and the motor 14 are started. The conveyor belt 17 will drive the tape varistor to move to the left, while the motor 14 will drive the right pulley 131 to rotate through the output terminal on the back. The right pulley 131 will drive the left pulley 131 to rotate through the belt 132, causing the rotating rod 121 fixedly connected to the back to rotate.

When the tip of the cutting blade 22 is inserted into the rectangular groove of the cutting platform 24, the tape varistor will be cut. Then, the cut tape varistor will slide along the inclined plane of the triangular wedge 26 and eventually leave the equipment. Then, rotate the threaded screw 231 in the opposite direction to drive the cutting blade 22 upward for the next round of cutting.
