Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically an automatic cutting device for terminal strips. Background Technology

[0002] Electrical connectors are widely used in various electronic devices to enable electrical connections between electronic components. They consist of several terminals and a plastic body for inserting the terminals. The terminals are mainly used to transmit signals or current. The plastic body is injection molded, while the terminals are usually manufactured by stamping metal strips. This involves stamping a roll of metal strip into a roll of terminal strip, then cutting it to the required terminal length, and finally installing the cut terminals into the plastic body to form the desired electrical connector.

[0003] In the process of manufacturing electrical connectors, multiple terminal modules need to be cut off from the material strip. After cutting, the material strip is cut into segments for easy recycling. This is usually done manually. During the cutting of terminal modules, the material strip may spring back, causing deviation in the position of the material strip, which in turn leads to damage to the material strip in subsequent processing and affects processing efficiency. To address this, we propose an automatic cutting device for terminal material strips. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cutting device for terminal strips.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cutting device for terminal strips, comprising a base, a support frame connected to the top left side of the base, a drive cylinder connected to the top center of the support frame, a connecting member connected to the drive end of the drive cylinder, a movable frame connected to the bottom end of the connecting member, positioning posts slidably connected to the middle of the front and rear sides of the movable frame, the top end of the positioning posts connected to the inner wall of the top side of the support frame, and a cutting table connected to the bottom end of the positioning posts, the bottom side of the cutting table connected to the base. On the top left outer wall, the cutting table is located inside the support frame. A connecting rod is connected to the middle of the bottom side of the movable frame. The bottom end of the connecting rod is connected to the cutting head. Extension frames are connected to both sides of the connecting rod. Sliding rods are slidably connected to the ends of the two extension frames that are far apart from each other. A pressure plate is connected to the bottom end of the sliding rod. A second spring is connected to the top end of the sliding rod. The bottom side of the second spring is connected to the top side of the extension frame through a fixed plate. A material strip is provided in the middle of the interior of the cutting table. The material strip is located below the cutting head.

[0006] As a further embodiment of this utility model: two vertical rods are connected to the middle of the top right side of the base, and a movable block is slidably connected inside each of the two vertical rods. Two tension rollers are rotatably connected to the side of the two movable blocks that are close to each other, and the tension rollers on the bottom side are located inside the right side of the base.

[0007] As a further embodiment of this utility model: an electric push rod is connected to the inner bottom side of the front vertical rod, and the driving end of the electric push rod is connected to the bottom end of the front moving block.

[0008] As a further embodiment of this utility model: a spring is provided on the outer side of each of the two positioning columns, the top end of the spring is connected to the bottom outer wall of the movable frame, and the bottom end of the spring is connected to the top outer wall of the cutting table.

[0009] As a further embodiment of this utility model: the distance between the two pressure plates and the cutting table is less than the distance between the cutting head and the cutting table, and the two pressure plates are at the same horizontal height.

[0010] As a further embodiment of this utility model: each of the two moving blocks has a movable groove on the top of its side that is close to each other, and the movable groove and the top tensioning roller are arranged accordingly.

[0011] As a further embodiment of this utility model: each of the two vertical rods is provided with a sliding groove adapted to the tension roller on the side that is close to each other, and the width of the sliding groove is smaller than the width of the moving block.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model uses a drive cylinder to move the movable frame on the connecting part downward, so that the cutting head moves downward synchronously to perform the cutting operation. During this process, the sliding rod is limited by the setting of the extension frame on both sides, so that the pressure plate below the sliding rod can move up and down with the sliding rod. Since the height of the pressure plate from the ground is less than the height of the cutting head from the ground, the pressure plate contacts the material strip first. During the continuous downward pressing, the second spring is stretched until the cutting is completed. The cutting head first disengages from the material strip, and then the pressure plate is reset by the spring. This avoids the material strip from rebounding during and after cutting, and avoids damage to the material strip in subsequent processing.

[0014] 2. This utility model uses an electric push rod to drive a moving block on one side to move within a vertical rod, causing the two tensioning rollers connected to the moving block to move up and down synchronously. This causes the material strip located between the two tensioning rollers to move accordingly, thereby allowing the overall tension of the material strip to be changed according to the actual situation, avoiding excessive tightness or looseness from affecting the cutting operation.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see the appendix Figure 1 -Appendix Figure 5This utility model discloses an automatic cutting device for terminal strips, comprising a base 1, a support frame 2 connected to the top left side of the base 1, a drive cylinder 3 connected to the top center of the support frame 2, a connector 4 connected to the drive end of the drive cylinder 3, a movable frame 5 connected to the bottom end of the connector 4, and positioning posts 6 slidably connected to the middle of the front and rear sides of the movable frame 5. The top end of the positioning post 6 is connected to the inner wall of the top side of the support frame 2, and the bottom end of the positioning post 6 is connected to a cutting table 15. The bottom side of the cutting table 15 is connected to the outer wall of the top left side of the base 1. Inside the support frame 2, a connecting rod 8 is connected to the middle of the bottom side of the movable frame 5. The bottom end of the connecting rod 8 is connected to the cutting head 9. Extension frames 10 are connected to both the left and right sides of the connecting rod 8. Sliding rods 11 are slidably connected to the ends of the two extension frames 10 that are far apart from each other. A pressure plate 12 is connected to the bottom end of the sliding rod 11. A spring 13 is connected to the top end of the sliding rod 11. The bottom side of the spring 13 is connected to the top side of the extension frame 10 through a fixed plate 14. A material strip 16 is provided in the middle of the inside of the cutting table 15. The material strip 16 is located below the cutting head 9.

[0025] In embodiment 1, two vertical rods 17 are connected to the middle of the top right side of the base 1. The interior of each vertical rod 17 is slidably connected to a movable block 18. The sides of the two movable blocks 18 that are close to each other are rotatably connected to two tension rollers 20. The bottom tension roller 20 is located inside the right side of the base 1. The bottom of the interior of the front vertical rod 17 is connected to an electric push rod 19. The drive end of the electric push rod 19 is connected to the bottom end of the front movable block 18. The top of the sides of the two movable blocks 18 that are close to each other is provided with a movable groove 21. The movable groove 21 and the top tension roller 20 are correspondingly arranged. The sides of the two vertical rods 17 that are close to each other are provided with a sliding groove that matches the tension roller 20. The width of the sliding groove is smaller than the width of the movable block 18.

[0026] Specifically, the electric push rod 19 drives the moving block 18 on one side to move within the vertical rod 17, causing the two tension rollers 20 connected to the moving block 18 to move up and down synchronously. This causes the material strip 16 located between the two tension rollers 20 to move along with it, thereby changing the overall tension of the material strip 16 according to the actual situation, avoiding excessive tightness or looseness from affecting the cutting operation.

[0027] In embodiment 2, spring 7 is provided on the outer side of each of the two positioning columns 6. The top end of spring 7 is connected to the bottom outer wall of the movable frame 5, and the bottom end of spring 7 is connected to the top outer wall of the cutting table 15. The distance between the two pressure plates 12 and the cutting table 15 is less than the distance between the cutting head 9 and the cutting table 15. The two pressure plates 12 are at the same horizontal height.

[0028] Specifically, the sliding rod 11 is limited by the extension brackets 10 on both sides, so that the pressure plate 12 below the sliding rod 11 can move up and down with the sliding rod 11. Since the height of the pressure plate 12 from the ground is less than the height of the cutting head 9 from the ground, the pressure plate 12 first contacts the material strip 16. During the continuous downward pressure, the second spring 13 is stretched until the cutting is completed. The cutting head 9 first disengages from the material strip 16, and then the pressure plate 12 is reset by the spring 13. This avoids the material strip 16 from rebounding during and after cutting. During the cutting process, the downward pressure is reduced to a certain extent by the first spring 7 on both sides.

[0029] Working principle:

[0030] In use, firstly, one end of the material strip 16 is passed between the two tension rollers 20 and conveyed by the conveying device. Then, the electric push rod 19 drives the moving block 18 on one side to move within the vertical rod 17, causing the two tension rollers 20 connected to the moving block 18 to move up and down synchronously. This causes the material strip 16 located between the two tension rollers 20 to move accordingly, thus allowing the overall tension of the material strip 16 to be adjusted according to the actual situation, avoiding excessive tightness or looseness that could affect the cutting operation. After completion, the drive cylinder 3 drives the moving frame 5 on the connecting piece 4 to move down, causing the cutting head 9 to move down synchronously for the cutting operation. During this process, the material strip 16 is conveyed by extending from both sides. The frame 10 limits the sliding rod 11, allowing the pressure plate 12 below the sliding rod 11 to move up and down with it. Since the height of the pressure plate 12 from the ground is less than that of the cutting head 9, the pressure plate 12 first contacts the material strip 16. During the continuous downward pressure, the second spring 13 is stretched until the cutting is completed. Then, the cutting head 9 first separates from the material strip 16, and the pressure plate 12 is reset by the spring 13. This prevents the material strip 16 from rebounding during and after cutting, thus preventing damage to the material strip 16 in subsequent processing. The entire operation is carried out with the material strip 16 fixed. Thus, the entire workflow is completed.
