Description

Technical Field

[0001] This utility model relates to the field of electronic component processing technology, specifically to a component lead cutting device. Background Technology

[0002] Electronic components are widely used in consumer products across various sectors of society. Most electronic components with pins need to be shaped before they can be soldered onto PCBAs. A key shaping step is the cutting of the pins, which is currently mainly done using cutting equipment with cutting blades.

[0003] For example, the electronic component pin cutting device disclosed in document CN206854544U consists of a frame, a shaping and cutting device, a control box, a movable cylinder, a positioning fixture, and a start switch. The movable cylinder is fixed to the frame, the shaping and cutting device is mounted on the movable cylinder, and the positioning fixture is located below the shaping and cutting device to provide positioning for the electronic component to be cut. By pressing the start switch, the movable cylinder can drive the shaping and cutting device to cut the pins of the electronic component in the positioning fixture.

[0004] Although existing lead cutting devices can cut the leads of electronic components, the lead is prone to bending and deformation under the pressure of the cutting blade during the falling process, which requires further trimming of the lead and causes inconvenience to the reshaping of the lead.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] To address the technical problem that components are prone to bending and deformation during the cutting process in the prior art, this utility model provides a component lead cutting device that limits the lead during the cutting process to prevent the lead from bending and deforming.

[0036] This utility model provides a component lead trimming device, such as... Figure 1-3 As shown, the device includes a cutting frame 10, a clamping module 20, a limiting block 30, a tension spring 40, and a cutting module 50. The clamping module 20 is disposed on the cutting frame 10 and is used to clamp the electronic component 10a to be cut. The limiting block 30 is slidably connected to the cutting frame 10 along the height direction of the cutting frame 10. The limiting block 30 is provided with a plurality of limiting holes 31, each limiting hole 31 being used for the insertion of the pins of the electronic component 10a. The two ends of the tension spring 40 are respectively connected to the cutting frame 10 and the limiting block 30, and are used to pull the limiting block 30 along the height direction of the cutting frame 10, providing the elastic force for the limiting block 30 to return to its original position. The cutting module 50 is mounted on the cutting frame 10 and is used to cut the pins of the electronic component 10a that protrude from the limiting block 30.

[0037] Specifically, the component lead trimming device comprises a trimming frame 10, a clamping module 20, a limiting block 30, a tension spring 40, and a trimming module 50. The clamping module 20 is mounted on the trimming frame 10 and can clamp the electronic component 10a to be trimmed. The limiting block 30 is slidably connected to the trimming frame 10 along its height direction and is provided with several limiting holes 31. When installing the electronic component 10a, the leads to be trimmed on the electronic component 10a are first inserted into the limiting holes 31 of the limiting block 30, and then the limiting block 30 is controlled to slide, so that the clamping module 20 can clamp the electronic component 10a. The electronic component 10a is clamped and fixed. By sliding the limiting block 30, the electronic component 10a of different sizes can be installed. After the electronic component 10a is clamped and fixed, the pins of the electronic component 10a extending out of the limiting block 30 can be cut by the cutting module 50. The pins are inserted into the limiting holes 31 to further limit the electronic component 10a. The tension spring 40 is connected to the limiting block 30 and can pull the limiting block 30 upward to prevent the limiting block 30 from sliding downward under the action of the pin during the cutting process, thereby stabilizing the pin and preventing the pin from bending and deforming during the cutting process of the cutting module 50.

[0038] In this embodiment, as Figure 1-2As shown, the cutting frame 10 is provided with a first sliding channel 11, and the limiting block 30 is slidably connected to the first sliding channel 11. Specifically, the limiting block 30 is slidably connected to the cutting frame 10 through the first sliding channel 11, and the limiting block 30 is not obstructed by any other objects on its front and rear sides. Therefore, the pins of the electronic component 10a can be inserted into the front side of the limiting block 30, and the pins can be cut on the rear side of the limiting block 30.

[0039] In some embodiments, such as Figure 1-2 As shown, the first sliding channel 11 has sliding grooves 111 on both sides, and the limiting block 30 has sliding protrusions 32 that are adapted to the sliding grooves 111. The sliding protrusions 32 are slidably connected to the sliding grooves 111. Specifically, through the cooperation of the sliding protrusions 32 and the sliding grooves 111, the limiting block 30 can be stably slid along the first sliding track.

[0040] In one embodiment, such as Figure 1 As shown, the clamping module 20 includes a fixed clamping seat 21 and a movable clamping seat 22. The fixed clamping seat 21 is fixed to the cutting frame 10 and located below the limiting block 30. The movable clamping seat 22 is disposed opposite to the fixed clamping seat 21 and is slidably connected to the cutting frame 10 along the width direction of the cutting frame 10. The movable clamping seat 22 can clamp the electronic component 10a with the fixed clamping seat 21 by sliding towards the fixed clamping seat 21. Specifically, when clamping the electronic component 10a, the movable clamping seat 22 is first slid away from the fixed clamping seat 21 by sliding the movable clamping seat 22. Then, the electronic component 10a is placed between the fixed clamping seat 21 and the movable clamping seat 22. The movable clamping seat 22 is then slid towards the fixed clamping seat 21, so that the fixed clamping seat 21 and the movable clamping seat 22 clamp and fix the electronic component 10a, thereby realizing the clamping of the electronic component 10a.

[0041] In one embodiment, such as Figure 1-2 As shown, the cutting frame 10 is also provided with a second sliding channel 12, which extends along the width direction of the cutting frame 10. The movable clamping seat 22 is mounted on the second sliding channel 12 and slidably connected to the second sliding channel 12. Specifically, by being mounted on the second sliding channel 12, the movable clamping seat 22 can achieve stable sliding along the width direction of the cutting frame 10.

[0042] In one embodiment, such as Figure 1-2As shown, the component lead cutting device also includes a compression spring 60. The two ends of the compression spring 60 abut against the cutting frame 10 and the movable clamping seat 22, respectively, to drive the movable clamping seat 22 to slide towards the fixed clamping seat 21. Specifically, the compression spring 60 can generate a driving force acting on the movable clamping seat 22 towards the fixed clamping seat 21, thereby increasing the clamping force of the movable clamping seat 22 and the fixed clamping seat 21, achieving stable clamping of the electronic component 10a.

[0043] In this embodiment, under normal circumstances, the movable clamping seat abuts against the fixed clamping seat under the elastic force of the compression spring 60. When clamping the electronic component 10a, the spring force must be overcome first to drive the movable clamping seat away from the fixed clamping seat. Then, the electronic component 10a is installed on the movable clamping seat. Then, the limiting block 30 is slid to make the limiting hole 31 of the limiting block 30 align with the pin of the electronic component 10a. Then, the movable clamping seat is slowly slid towards the fixed clamping seat. While the movable clamping seat clamps the electronic component 10a with the fixed clamping seat, it drives each pin of the electronic component 10a to be inserted into each limiting hole 31 of the limiting block 30, thereby realizing the clamping of the electronic component 10a.

[0044] In this embodiment, the structures of the opposite sides of the movable clamping base 22 and the fixed clamping base 21 can be adapted to the shape of the end of the electronic component 10a to be clamped.

[0045] In one embodiment, such as Figure 1 As shown, the movable clamping base 22 is provided with a pin slot 221, which is used to mount the lower pin of the electronic component 10a. Specifically, the pin slot 221 can be used to mount the electronic component 10a, which also has pins at its lower end. The movable clamping base and the fixed clamping base fix the electronic component 10a by clamping the lower pin of the electronic component 10a.

[0046] In this embodiment, the lower pin of the electronic component 10a is a bent structure. When the movable clamp moves toward the fixed clamp, it will cause the lower pin of the electronic component 10a to adhere to the lower surface of the fixed clamping base 21. Thus, by limiting the bent pin, the electronic component 10a is clamped. During the cutting process of the cutting module 50, the part of the pin that extends out of the fixed clamping base 21 can be cut together, and the cutting of two sets of pins can be achieved at the same time.

[0047] In one embodiment, such as Figure 1-3 As shown, the limiting block 30 is provided with a limiting port 33, which is used for inserting one end of the setting pin of the electronic component 10a. Specifically, by inserting one end of the setting pin of the electronic component 10a into the limiting port 33, the limiting block 30 can further limit the electronic component 10a.

[0048] In one embodiment, such as Figure 2 As shown, the cutting module 50 includes a cylinder 51 and a cutting blade 52. The cutting blade 52 cuts into the cutting frame 10 and is flush with the side of the pin extending from the limiting block 30. The cylinder 51 is fixed to the cutting frame 10 and connected to the cutting blade 52 to drive the cutting blade 52 to move up and down against the cutting frame 10 to cut the pin extending from the limiting block 30. Specifically, when cutting the pin, the cylinder 51 drives the cutting blade 52 to descend, cutting the part of the upper pin extending from the limiting block 30 and the part of the lower pin extending from the fixing clamp 21, ultimately achieving the cutting of the pin of the electronic component 10a.

[0049] In this embodiment, as Figure 2 As shown, the cutting frame 10 is also provided with a cutting slide 13, and the cutting blade 52 is slidably connected to the cutting slide 13.

[0050] In one embodiment, such as Figure 1-2 As shown, the cutting frame 10 is also provided with a discharge port 14, which is located below the limiting block 30. The component lead cutting device also includes a discharge drawer 70, which is removably mounted on the cutting frame 10 and located below the discharge port 14. Specifically, the material residue formed during the lead cutting process will fall from the discharge port 14 into the discharge drawer 70 for subsequent unified processing.

[0051] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail as follows: Before cutting the pins of electronic component 10a, electronic component 10a is clamped. During the clamping process, the spring force is first overcome, and the movable clamping seat is driven away from the fixed clamping seat. Then, the lower bent pins of electronic component 10a are installed in the pin groove 221 of the movable clamping seat. Then, the limiting block 30 is slid to make the limiting hole 31 of the limiting block 30 align with the upper pins of electronic component 10a. Then, the movable clamping seat... Slowly slide the movable clamp towards the fixed clamping seat. While the movable clamping seat clamps the electronic component 10a with the fixed clamping seat, it drives the pins at the upper end of the electronic component 10a to be inserted into the limiting holes 31 of the limiting block 30, thereby realizing the clamping of the electronic component 10a. After the clamping is completed, the cylinder 51 drives the cutting blade 52 to descend, cutting the part of the upper pin that extends out of the limiting block 30 and the part of the lower pin that extends out of the fixed clamping seat 21. The material residue formed by cutting falls into the material drawer 70 through the material discharge port 14. After the cutting is completed, control the movable clamping seat to slide away from the fixed clamping seat and take out the electronic component 10a.

[0052] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
