Description

Technical Field

[0001] This utility model relates to the technical field of electronic component cutting, and in particular to an electronic component lead cutting machine. Background Technology

[0002] With the rapid development of the electronics industry, the demand for electronic components is increasing day by day, and pin processing of electronic components is an important part of the manufacturing process.

[0003] Currently, electronic component lead trimming equipment on the market is mainly divided into three types: manual, semi-automatic, and fully automatic. Manual operation is inefficient and prone to causing inconsistent lead lengths or component damage due to improper operation. Semi-automatic lead trimming machines improve efficiency to some extent, but require manual assistance for feeding and are difficult to achieve continuous production. Although fully automatic lead trimming machines have a high degree of automation, the equipment cost is expensive and has limited adaptability to the size of electronic components, making it difficult to meet diverse production needs.

[0004] The existing technical solutions have the following drawbacks: traditional electronic component lead cutting machines have poor precision and cannot meet the requirements for cutting electronic components of different sizes. Utility Model Content

[0005] The purpose of this invention is to provide an electronic component lead-cutting machine to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An electronic component lead-cutting machine includes a worktable and a first screw, a round rod, a crossbeam, and a crossbar disposed inside the worktable. Both ends of the first screw, round rod, crossbeam, and crossbar pass through the left and right ends of the worktable. The machine is characterized in that a ratchet device, a lead-cutting device, and a guide device are symmetrically arranged on the first screw, round rod, and crossbar.

[0008] The ratchet device is sleeved and installed in the middle of the first screw, the right end of the first screw extends to the outside of the right end of the worktable, and a manual crank is fixedly installed at the front end of the first screw. The ratchet device is used to transmit electronic components.

[0009] The cutting device is slidably mounted in the middle of the round rod, and the cutting device is spaced apart at the right end of the ratchet device. The cutting device is used to cut electronic components.

[0010] The guide device is slidably mounted on the left end of the ratchet device, and the guide device is used to guide electronic components into the ratchet device.

[0011] By adopting the above technical solution, the positions of the ratchet device, the cutting device, and the guide device are adjusted according to the size of the electronic components that need to be cut. After being adjusted to the appropriate position, they are fixed. Then, the rows of glued electronic components are fed into the guide device. Then, the manual crank is turned, and the cutting device cuts the two ends of the electronic components under the drive of the ratchet device.

[0012] In a further embodiment, the ratchet device includes a first ratchet and a second ratchet. The center hole of the second ratchet is provided with a thread. The first ratchet is spaced apart at the front end of the second ratchet. The first ratchet is fixedly mounted on the first screw, and the second ratchet is slidably mounted on the first screw. The center holes of the first ratchet and the second ratchet are both sleeved in the middle of the first screw.

[0013] By adopting the above technical solution, the second ratchet can be rotated according to the required length of the lead of the electronic component, thereby adjusting the distance between the second ratchet and the first ratchet. Then, the manual crank can be turned to drive the ratchet device on the first screw to rotate.

[0014] In a further embodiment, the clipping device includes:

[0015] A sleeve is slidably mounted on a round rod. The top of the inner ring of the sleeve is provided with a first threaded hole that runs vertically through the top and bottom. A first locking bolt is screwed into the first threaded hole.

[0016] A circular blade, which is fixedly installed at the front end of the sleeve;

[0017] The long blade is disposed inside the first ratchet and the second ratchet. The shearing surface of the long blade is higher than the bottom end of the round blade. An integrally formed ear plate is provided at the left end of the long blade. A through hole is provided at the top end of the ear plate. The ear plate is slidably mounted on the crossbeam. The front end and the rear end of the ear plate extend forward and backward, respectively. A second threaded hole is provided at the left end of the protrusion, and a second locking bolt is screwed into the second threaded hole.

[0018] By adopting the above technical solution, the ear plate on the crossbeam and the sleeve on the round rod are moved according to the required cutting length of the electronic component. When they are adjusted to the appropriate position, they are locked by the second locking bolt and the first locking bolt respectively, so as to realize the position adjustment of the round blade and the long blade, and meet the requirements of cutting both ends of electronic components of different sizes.

[0019] In a further embodiment, the guiding device includes a first guide plate and a second guide plate. The bottom left side of the first guide plate is provided with a downward second protrusion, which is slidably connected to a crossbar.

The top of the second guide plate is provided with a fourth threaded hole that passes through vertically. The third threaded hole and the fourth threaded hole are coaxially aligned, and a third locking bolt is screwed into the third threaded hole and the fourth threaded hole.

[0020] By adopting the above technical solution, rotating the third locking bolt can adjust the distance between the first guide plate and the second guide plate, enabling the cutting of both ends of electronic components of different heights. The design of the right end of the first guide plate extending to the bottom of the round rod is beneficial for transporting the electronic component group to the front of the cutting device, thus achieving precise cutting of the electronic components.

[0021] In a further embodiment, a second screw is also included, which is parallel to the first screw. A first blocking ring and a second blocking ring are screwed onto the second screw at intervals. An integrally formed vertical rod is provided at the front end of the second screw, and the vertical rod is screwed onto the outer wall of the right end of the worktable.

[0022] By adopting the above technical solution, the feeding position of electronic components in the lead-cutting machine can be restricted, making it easier for the electronic component group to enter the guiding device and ensuring that the lead-cutting length is consistent.

[0023] In a further embodiment, a drawer is slidably mounted on the inner top of the workbench.

[0024] By adopting the above technical solution, it is beneficial to collect the electronic components after the leads have been cut.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. By adjusting the positions of the ratchet device, the cutting device, and the guide device according to the size of the electronic components to be cut, and fixing them in the appropriate positions, the rows of glued electronic components are fed into the guide device.

[0036] Example 1:

[0037] like Figures 1-4As shown, an electronic component lead-cutting machine includes a worktable 1 and a first screw 2, a round rod 3, a crossbeam 4, and a crossbar 5 disposed inside the worktable 1. Both ends of the first screw 2, round rod 3, crossbeam 4, and crossbar 5 pass through the left and right ends of the worktable 1. The worktable has a concave cross-section along the vertical direction. A ratchet device 6, a lead-cutting device 7, and a guide device 8 are symmetrically arranged on the first screw 2, round rod 3, and crossbar 5, respectively. The ratchet device 6 is sleeved and installed in the middle of the first screw 2. The right end of the first screw 2 extends to the outside of the right end of the worktable. A manual crank 11 is fixedly installed at the front end of the first screw 2. Device 6 is used to transport electronic components; a shearing device 7 is slidably installed in the middle of the round rod 3, and the shearing device 7 is spaced apart at the right end of the ratchet device 6, and the shearing device 7 is used to cut electronic components; a guide device 8 is slidably installed in the left end of the ratchet device 6, and the guide device 8 is used to guide electronic components into the ratchet device 6, and also includes a second screw 9, the screw 9 being parallel to the first screw 2, the second screw 9 having a first blocking ring and a second blocking ring screwed at intervals, the front end of the second screw 9 having an integrally formed vertical rod, the vertical rod being screwed to the outer wall of the right end of the workbench 1; a drawer 10 is slidably installed at the top of the inside of the workbench 1.

[0038] like Figure 2 As shown, the ratchet device 6 includes a first ratchet 61 and a second ratchet 62. The center hole of the second ratchet 62 is provided with a thread. The first ratchet 61 is spaced apart at the front end of the second ratchet 62. The first ratchet 61 is fixedly installed on the first screw 2, and the second ratchet 62 is slidably installed on the first screw 2. The center holes of the first ratchet 61 and the second ratchet 62 are both sleeved in the middle of the first screw 2.

[0039] like Figure 3 As shown, the shearing device 7 includes: a sleeve 71, which is slidably mounted on the round rod 3. The top of the inner ring of the sleeve 71 is provided with a first threaded hole that runs vertically through the top and bottom, and a first locking bolt is screwed into the first threaded hole; a round blade 72, which is fixedly mounted on the front end of the sleeve 71; and a long blade 73, which is disposed inside the first ratchet 61 and the second ratchet 62. The shearing surface of the long blade 73 is higher than the bottom end of the round blade 72. An integrally formed ear plate is provided at the left end of the long blade 73. A through hole that runs from front to back is provided at the top end of the ear plate. The ear plate is slidably mounted on the crossbeam 4. The front end and the rear end of the ear plate extend forward and backward, respectively. A second threaded hole that runs from left to right is opened at the left end of the protrusion, and a second locking bolt is screwed into the second threaded hole.

[0040] like Figure 4As shown: The guiding device 8 includes a first guiding plate 81 and a second guiding plate 82. The bottom left side of the first guiding plate 81 is provided with a downward second protrusion, which is slidably connected to the crossbar 5. The right end of the first guiding plate 81 extends to the bottom of the round rod 3. The second guiding plate 82 is spaced apart from the top of the first guiding plate 81. The top of the first guiding plate 81 is provided with a third threaded hole, which passes through the first guiding plate 81 and the second protrusion. The top of the second guiding plate 82 is provided with a fourth threaded hole that passes through from top to bottom. The third threaded hole and the fourth threaded hole are coaxially aligned, and a third locking bolt is screwed into the third threaded hole and the fourth threaded hole.

[0041] Specific implementation process: According to the size of the electronic component to be cut, rotate the third locking bolt to adjust the distance between the first guide plate 81 and the second guide plate 82 so that the opening height is slightly greater than the height of the two feet of the electronic component. Because the second protrusion at the bottom of the first guide plate 81 slides along the crossbar 5, the guide device 8 can be moved back and forth as a whole to ensure that the distance between the two guide devices 8 is greater than the width of the electronic component group, ensuring that the electronic component can smoothly enter the ratchet device 6. Because the first ratchet is fixedly installed on the first screw and the center hole of the second ratchet is threaded, the distance between the first ratchet 61 and the second ratchet 62 can be adjusted by rotating the second ratchet. The round blade 72 of the cutting device 7 is fixed to the round rod 3 by the sleeve 71. Loosening the first locking bolt allows the sleeve 71 to slide up and down, and loosening the second locking bolt allows the long blade 73 to move left and right. The position of the round blade 72 on the round rod 3 can be adjusted by sliding the sleeve 71, and the position of the long blade 73 on the crossbeam 4 can be adjusted by sliding the ear plate to accommodate electronic components of different widths. The machine performs lead cutting. Rotating the manual crank 11 drives the first ratchet 61 and the second ratchet 62 to move axially along the first screw 2. By rotating the first and second blocking rings on the second screw 9, the feeding position of the electronic component in the lead cutting machine can be restricted to ensure consistent lead cutting length. The vertical rod is used to fix the second screw 9 to prevent it from shifting. When the electronic component is fed into the worktable 1, the ratchet device 6 guides the component from the left to the lead cutting station on the right by rotating. The tooth groove design of the ratchet device 6 ensures stable component transmission and avoids deviation. For leads of different diameters, the cut leads fall into the drawer 10 at the bottom of the worktable 1. The manual crank 11 continues to rotate, driving the ratchet device 6 to push the electronic component forward. The leads are cut when they pass through the round blade 72 and the long blade 73. The cut electronic component is discharged from the right, completing the processing. This lead cutting machine can flexibly adapt to electronic components of different sizes, achieving efficient and precise lead cutting operations. After adjusting each device, the bolts need to be tightened to ensure stability and avoid deviation during the cutting process.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.
