Description

Technical Field

[0001] This utility model belongs to the field of electronic components and equipment, and in particular relates to a tape and reel resistor forming machine. Background Technology

[0002] Currently, resistors, as an indispensable electronic component in the electronics industry, are widely used in the production of various electronic products. During the production process, when resistors are packaged in batches, they are arranged in parallel. The resistor leads are laid out horizontally and aligned with the resistor body. Each resistor is arranged in parallel, and adhesive tape is wrapped around the outside of the leads to allow the resistor strip to be wound.

[0003] Before resistors can be installed on a circuit board, they usually need to be cut and bent, which requires the use of a resistor forming machine.

[0004] A novel resistance forming machine is disclosed in Chinese utility model patent with announcement number CN202171990U, which includes a control device and a mechanical transmission device. The control device includes a control cabinet, control buttons and a keyboard on the control cabinet, an LED display, and a control microcontroller circuit board, relays, thermal protection circuit breakers, stepper motors and their driving devices located in the control cabinet. The mechanical transmission device includes a feeding mechanism, a transmission mechanism, a shearing mechanism and a forming mechanism respectively connected to the machine frame, and a roll-up mechanism.

[0005] In existing technologies, similar to the resistor forming machine described above, the resistor strip is usually guided by a guide block when cutting resistor elements. However, in actual use, it has been found that when the resistor strip passes through the guide block, the guide block will jam the resistor strip when it bends. Moreover, the contact area between the resistor strip and the guide block is large, which causes the resistor strip to jam and not pass smoothly through the guide block, affecting the processing efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a tape and reel resistor forming machine to solve the problem of resistance tape getting stuck and not flowing smoothly through the guide block, which affects processing efficiency.

[0010] A cutting mechanism is mounted on the frame and located on one side of the feeding mechanism;

[0011] The guiding mechanism includes a support beam, guide blocks, and rollers. The support beam is fixedly connected to the frame and is located on the side of the feeding mechanism away from the cutting mechanism. Two parallel guide blocks are provided on the support beam, and guide grooves are provided on the guide blocks. Multiple rollers are provided on the upper and lower surfaces of the guide grooves.

[0014] As a further description of the above technical solution:

[0036] Please see Figure 1-3 This utility model provides a tape and reel resistance forming machine, which includes:

[0037] Rack 1;

[0038] Feeding mechanism 2, which is mounted on the frame 1;

[0039] A cutting mechanism 3 is mounted on the frame 1 and is located on one side of the feeding mechanism 2.

[0040] The guiding mechanism includes a supporting beam 4, a guide block 5, and rollers 6. The supporting beam 4 is fixedly connected to the frame 1 and is located on the side of the feeding mechanism 2 away from the cutting mechanism 3. Two parallel guide blocks 5 are provided on the supporting beam 4, and guide grooves 7 are provided on the guide blocks 5. Multiple rollers 6 are provided on the upper and lower surfaces of the guide grooves 7.

[0041] The roller 6 is rotatably connected to the roller frame 8, which is connected to the guide block 5 via a screw 9. A fastening nut 10 is mounted on the screw 9. A first spring 11 is positioned between the guide block 5 and the roller frame 8, passing through the screw 9. When the roller is subjected to a large force, the roller frame can move up and down due to the presence of the first spring, providing space for deformation. This, in turn, allows the resistance band to deform, preventing damage in case of jamming.

[0042] A sliding ring 12 is provided on the guide block 5, and the sliding ring 12 is slidably connected to the support beam 4. A plum blossom knob 13 on the guide block 5 passes through the guide block 5, and the sliding ring 12 abuts against the support beam 4. By rotating the plum blossom knob, the sliding ring can be tightened or loosened, thereby adjusting the distance between the two guide blocks to accommodate different resistance molding processes.

[0043] The feeding mechanism 2 includes a drive shaft 21 rotatably connected to the frame 1. Four gears 22 are mounted on the drive shaft 21, with gaps between them. The teeth of the four gears sequentially engage with each resistive element on the resistance strip, pulling the resistance strip forward.

[0044] One end of the drive shaft extends out of the frame 1 and connects to the rotating handle 14.

[0045] The cutting mechanism 3 includes a connecting shaft 31 mounted on a frame 1. Two cutters 32 are mounted on the connecting shaft 31, and a retaining ring 33 is also mounted on the connecting shaft 31. The two cutters are located between the two retaining rings 33, and a second spring 15 is positioned between the retaining rings 33 and the cutters 32. The cutters are circular and coaxially mounted with the connecting shaft. There is a gap between the two cutters, and the opposing sidewalls of the two cutters are in contact with the opposite side of the gear, ensuring that the resistance band is cut off by the cutters after being pulled by the gear.

[0046] The frame 1 is equipped with a receiving box 16, and the bottom of the receiving box 16 is provided with ball bearings, which are rotatably connected to a sliding groove 17 on the frame 1. The ball bearings and sliding groove facilitate the pulling out of the receiving box, thereby making it convenient to pick up materials.

[0047] Working principle: By setting rollers in the guide groove of the guide block, the resistance strip can make rolling contact with the guide block, and at the same time, the contact area between the resistance strip and the guide block can be reduced, so that the resistance strip can move more smoothly in the guide block.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
