Description

Technical Field

[0001] This utility model relates to the field of equipment technology for manufacturing current collectors, and in particular to a terminal strip cutting device. Background Technology

[0002] Electrical connectors and terminal blocks are accessories used to achieve electrical connections. In industry, they are classified as electrical connectors. With the increasing level of industrial automation and the increasingly stringent and precise requirements of industrial control, the usage of terminal blocks is gradually increasing. With the development of the electronics industry, the application range of terminal blocks is expanding, and the types are also increasing. In addition to PCB board terminals, the most widely used types include hardware terminals, nut terminals, spring terminals, etc.

[0003] Currently, in the process of inserting terminal blocks into power connectors, it is necessary to first cut off the terminal blocks one by one from the terminal block strip, and then assemble them into the terminal block socket of the power connector by transferring, rotating horizontally, and flipping them vertically. For example, the patent with publication number CN201493533U discloses a terminal block cutting mechanism, which uses a cylinder to drive a cutter to cut off the terminal blocks one by one from the terminal block strip for subsequent insertion operations. However, in actual operation, it is found that the terminal block strip will shift during cutting, resulting in poor cutting accuracy and poor cutting effect. Utility Model Content

[0004] To address the issue of poor stability in existing cutting mechanisms, this invention provides a terminal strip cutting device. The device uses a clamping block above the terminal strip to fix the strip, and then uses the cooperation of a top rod and a cutting block to cut off the terminals on the fixed strip. The cutting is stable and the cutting effect is good.

[0005] This utility model provides a terminal strip cutting device, including a frame, a feeding platform, and a cutting section. The cutting section, mounted on the frame, is connected to the feeding platform. The cutting section includes a clamping block and a cutting block arranged opposite each other, with a cutting gap between the clamping block and the cutting block to accommodate the terminal strip. The clamping block can move longitudinally towards the cutting gap. The clamping block positions the terminal strip fed into the cutting gap, and then the cutting block cuts off the terminals from the terminal strip, ensuring stable cutting.

[0006] Furthermore, it also includes a drive unit one for driving the clamping block to move longitudinally and a drive unit two that cooperates with the cutting block. The clamping block is positioned above the terminal strip, and the cutting block is positioned below the terminal strip. The clamping block moves longitudinally via the drive unit one, while the cutting block completes the cutting via the drive unit two.

[0007] Furthermore, the drive unit includes a movable plate, a pressure rod, and a cylinder. The middle part of the pressure rod is rotatably connected to the frame, one end of the pressure rod is connected to the telescopic end of the cylinder, and the other end is connected to the movable plate. A clamping block is located at the bottom of the movable plate. The cylinder drives the end of the pressure rod to move, and the clamping block is moved downward using the lever principle to clamp the terminal strip.

[0008] Furthermore, the frame is equipped with a clamping rail that mates with the movable plate, allowing the movable plate to slide longitudinally along the clamping rail. The cooperation between the clamping rail and the movable plate ensures the stability of the clamping block's sliding motion.

[0009] Furthermore, a limiting block for positioning the pressure rod is provided at the top of the frame. One end of the limiting block is fixed on the frame, and the other end is inclined in the direction of rotation of the pressure rod.

[0010] Furthermore, the bottom of the clamping block is also equipped with positioning feet that are compatible with the terminal strip, and at least two positioning feet are provided. The positioning feet can extend into the chain hole to effectively position the strip.

[0011] Furthermore, the second drive unit includes a movable seat, a push rod, and a second cylinder. One end of the movable seat is connected to the telescopic end of the second cylinder, and the other end movably abuts against the push rod. The movable seat is driven by the second cylinder to raise the push rod and cooperate with the cutting block to complete the cutting.

[0012] Furthermore, the outer surface of the cutting block is the cutting surface, and the frame is equipped with a cutting track that cooperates with the push rod. The push rod can slide longitudinally along the cutting track and abut against the cutting surface. The push rod is slidably set outside the cutting surface, and cutting is performed through the abutment action between the push rod and the cutting surface.

[0013] Furthermore, the end of the movable seat furthest from the second cylinder is provided with a wedge surface, and the bottom of the push rod is provided with a roller that abuts against the wedge surface. Springs are also provided on both sides of the roller to ensure that the roller always abuts against the wedge surface. Through the height difference of the wedge surface and its cooperation with the roller, the push rod is driven to move longitudinally.

[0014] Furthermore, an adjusting rail is provided at the bottom of the frame, with the frame slidingly engaging with the adjusting rail. A limiting seat for frame positioning is also provided at the end of the adjusting rail. The distance between the cutting device and the feeding platform is adjusted via the adjusting rail.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides a terminal strip cutting device, which fixes the strip by a clamping block set above it, and then uses the cooperation between the top rod and the end face of the cutting block to cut the terminals on the strip. The cutting is stable and the cutting effect is good. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] To achieve stability in the cutting of terminal strip 8, a terminal strip cutting device is designed, such as... Figure 1 As shown, the system includes a frame 6, a feeding platform 7, and a cutting section. The cutting section, mounted on the frame 6, is connected to the feeding platform 7. The cutting section includes a clamping block 1 and a cutting block 2 arranged opposite each other. A cutting gap 3 is formed between the clamping block 1 and the cutting block 2 to accommodate the terminal strip 8. The clamping block 1 can move longitudinally toward the cutting gap 3. When the terminal strip 8 is fed to the cutting gap 3, the clamping block 1 moves down, causing its bottom positioning foot 11 to abut into the strip hole, positioning the terminal strip 8. At the same time, the top rod 52, which is opposite to the cutting point of the terminal strip 8, rises to abut against the cutting surface 21 of the cutting block 2, thereby smoothly cutting the terminal off the strip and completing the cutting of the terminal strip 8.

[0025] To facilitate the collection of waste strips, a waste bin 9 is provided at the end of the terminal strip 8 in the conveying direction. The waste bin 9 is fixed to the frame 6 by bolts, and the cut strips fall into the waste bin 9.

[0026] To facilitate the adjustment of the position of the frame 6, an adjustment rail 63 is provided at the bottom of the frame 6. The frame 6 and the adjustment rail 63 are slidably engaged. The end of the adjustment rail 63 is also provided with a limit seat for positioning the frame 6. The limit seat can prevent the frame 6 from sliding excessively.

[0027] like Figure 2 As shown, it also includes a drive unit 4 for driving the clamping block 1 to move longitudinally and a drive unit 5 that cooperates with the cutting block 2. The clamping block 1 is disposed above the terminal strip 8, and the cutting block 2 is disposed below the terminal strip 8. The clamping block 1 is driven to slide longitudinally by the drive unit 4, and the terminal is cut off from the strip by the longitudinally sliding drive unit 5 cooperating with the cutting block 2.

[0028] Specifically, the drive unit 4 includes a movable plate 41, a pressure rod 42, and a cylinder 43. The middle part of the pressure rod 42 is rotatably connected to the frame 6. One end of the pressure rod 42 is connected to the telescopic end of the cylinder 43, and the other end is connected to the movable plate 41. The clamping block 1 is located at the bottom of the movable plate 41. When the telescopic end of the cylinder 43 extends, it drives the rear end of the pressure rod 42 to lift, and the other end of the pressure rod 42 connected to the movable plate 41 will move down, causing the clamping block 1 at the bottom of the movable plate 41 to clamp and position the terminal material strip 8.

[0029] To ensure the stable sliding of the movable plate 41, the frame 6 is provided with a clamping rail 61 that cooperates with the movable plate 41, and the movable plate 41 can slide longitudinally along the clamping rail 61.

[0030] To prevent the pressure rod 42 from rotating excessively, a limiting block 44 for positioning the pressure rod 42 is provided on the top of the frame 6. One end of the limiting block 44 is fixedly set on the frame 6, and the other end is tilted in the direction of rotation of the pressure rod 42. After the rear end of the pressure rod 42 is raised at a certain angle, it is blocked by the limiting block 44.

[0031] To ensure the effective clamping and positioning of the terminal strip 8, the bottom of the clamping block 1 is also provided with positioning feet 11 that are adapted to the terminal strip 8. At least two positioning feet 11 are provided. The positioning feet 11 extend into the strip hole to prevent the strip from shifting horizontally.

[0032] Specifically, the second drive unit 5 includes a movable seat 51, a push rod 52, and a second cylinder 53. One end of the movable seat 51 is connected to the telescopic end of the second cylinder 53, and the other end is movably abutted against the push rod 52. The movable seat 51, driven by the second cylinder 53, drives the push rod 52 to slide longitudinally.

[0033] like Figure 3 and 4As shown, the outer side of the cutting block 2 is the cutting surface 21. The frame 6 is provided with a cutting track 62 that cooperates with the push rod 52. The push rod 52 can slide longitudinally along the cutting track 62 and abut against the cutting surface 21. There is a cutting point between the terminal and the material strip 8. When the cutting point of the material strip is moved to directly above the push rod 52, the push rod 52 is raised by the action of the movable seat 51 to abut against the cutting surface 21, thereby smoothly cutting the terminal off the material strip.

[0034] To enable the push rod 52 to reciprocate up and down within a certain range, the movable seat 51 has a wedge surface 511 at the end away from the cylinder 53. The bottom of the push rod 52 has a roller 54 that abuts against the wedge surface 511. Springs 55 are also provided on both sides of the roller 54 to keep the roller 54 abutting against the wedge surface 511. The wedge surface 511 has a height difference. When the roller 54 is in the lower position of the wedge surface 511, the push rod 52 does not contact the cutting surface 21. When the roller 54 is in the higher position of the wedge surface 511, the push rod 52 abuts against the cutting surface 21 to cut the terminal material strip 8.

[0035] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
