Technical Field

[0001] This utility model relates to the field of electronic component processing technology, specifically to an electronic component pin cutting mechanism. Background Technology

[0002] Electronic components often require lead trimming during manufacturing to meet mounting dimensions or soldering requirements. Traditional lead trimming methods rely heavily on manual operation or semi-automated equipment, resulting in low efficiency, poor accuracy, and difficulty in ensuring consistency. Especially as electronic components become smaller and denser, the lead pitch is decreasing, placing even higher demands on trimming precision.

[0003] Although there are some automated cutting devices in the existing technology, the following problems still exist: First, most devices lack an effective centering and clamping mechanism, which makes the components prone to displacement during the cutting process, affecting the cutting quality; Second, the cutting mechanism is mostly unidirectional or single-point force application, which can easily cause pin deformation or uneven cut surface; Third, the waste collection system is imperfect, and the waste after cutting is easy to accumulate inside the equipment, affecting the stability and service life of the equipment.

[0004] Therefore, there is an urgent need for a pin cutting mechanism that can achieve automatic centering, stable clamping, bidirectional collaborative cutting, and automatic waste collection to improve cutting accuracy, efficiency, and equipment reliability. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figure 1-7 As shown, this embodiment provides an electronic component lead cutting mechanism, including a fixed base 1. Two sets of corresponding cutting devices 2 are provided on the upper part of the fixed base 1, and a centering clamping device 4 and a positioning fixing device 5 are disposed between the two sets of cutting devices 2. The centering clamping device 4 and the positioning fixing device 5 are correspondingly arranged, and a reference block 6 for placing the electronic component 11 is provided between the centering clamping device 4 and the positioning fixing device 5. Through the coordinated layout of the cutting device 2, the centering clamping device 4, and the positioning fixing device 5, the automatic centering, fixing, and cutting of the electronic component 11 are integrated, improving cutting accuracy and efficiency. The reference block 6 ensures that the electronic component 11 has a stable positioning reference during the cutting process, avoiding uneven lead cutting caused by positional deviation.

[0023] The upper part of the fixed base 1 is equipped with a cutting transverse module 7 for driving the two sets of cutting devices 2 to move laterally relative to each other. The two sets of cutting devices 2 are connected to the cutting transverse module 7 through the mounting base 3 and are driven by the cutting transverse drive mechanism 8. The cutting transverse module drives the two sets of cutting devices to move laterally relative to each other, which can accommodate electronic components of different sizes and enhance the versatility and flexibility of the mechanism. By controlling the movement of the cutting devices 2 through the cutting transverse drive mechanism 8, precise position control is achieved and the repeatability of cutting is improved.

[0024] Please see Figures 4-5 As shown, the cutting device 2 includes an upper cutter 201 and a lower cutter 202 arranged opposite to each other. The upper cutter 201 and the lower cutter 202 are detachably connected to the upper cutter connecting block 203 and the lower cutter connecting block 204, respectively. The upper cutter connecting block 203 and the lower cutter connecting block 204 are connected to the cutting transverse movement module through the upper cutter holder 205 and the lower cutter holder 206, respectively, and are driven by the cutting drive mechanism 207. The symmetrical design of the upper and lower cutters enables bidirectional cutting, improving cutting efficiency and the flatness of the lead cut. The upper cutter 201 and the upper cutter connecting block 203, as well as the lower cutter 202 and the lower cutter connecting block 204, are all detachably connected by bolts. The detachable cutter connection method facilitates replacement and maintenance, reducing operating costs.

[0025] The upper cutter holder 205 and the lower cutter holder 206 are respectively connected to an upper transmission block 208 and a lower transmission block 209 on the side away from the upper cutter connecting block 203 and the lower cutter connecting block 204. The upper transmission block 208 and the lower transmission block 209 are hinged together, and the output end of the cutting drive mechanism 207 is connected to the upper transmission block 208. The hinged transmission structure realizes the synchronous movement of the upper and lower cutters, ensuring the balanced distribution of force during the cutting process and avoiding deformation or damage to the pins due to uneven force. The design of the transmission block enhances the rigidity and stability of the mechanism and improves the reliability of the cutting action.

[0026] The lower cutter connecting block 204 has a collection box 210 for collecting waste material connected to its upper part, and an outlet pipe 211 connected to its lower part. The lower cutter connecting block 204 also has a through groove connecting the collection box 210 and the outlet pipe 211. The design of the collection box 210 and the outlet pipe 211 enables automatic collection and discharge of waste material during the cutting process, preventing waste accumulation from affecting cutting accuracy or equipment operation. The through groove design ensures that waste material smoothly enters the outlet pipe 211 and is discharged.

[0027] Please see Figures 6-7 As shown, the centering clamping device 4, the positioning and fixing device 5, and the reference block 6 are all mounted on a mounting frame 9. The centering clamping device 4 includes a first telescopic drive mechanism 401 mounted on the mounting frame 9. The output end of the first telescopic drive mechanism 401 is connected to a first transmission block 402, and a clamping assembly is mounted on the first transmission block 402. The first telescopic drive mechanism 401 is a cylinder, responsible for the feeding and retraction of the entire clamping assembly, realizing automated switching of the clamping station. The first transmission block ensures that the driving force can be evenly transmitted to the clamping assembly, avoiding uneven loading and making the operation smooth and reliable.

[0028] The clamping assembly includes a left gripper 403 and a right gripper 404 arranged opposite to each other. The left gripper 403 and the right gripper 404 are connected to the gripper lateral movement module through a left gripper connecting block 405 and a right gripper connecting block 406, respectively, and are driven by a gripper drive mechanism 407. The gripper drive mechanism 407 is mounted on the first transmission block 402 via a pad 408. The gripper drive mechanism 407 is a cylinder that drives the left and right grippers to move synchronously in opposite directions, realizing the automatic centering function of electronic components and ensuring that the component body is always located in the center position of the reference block 6, which is a key prerequisite for ensuring consistent cutting lengths in subsequent processes. The gripper lateral movement module and the gripper drive mechanism 407 provide precise clamping force control, avoiding excessively tight or loose clamping.

[0029] The positioning and fixing device 5 includes a second telescopic drive mechanism 501 mounted on the mounting bracket 9. The output end of the second telescopic drive mechanism 501 is connected to a second transmission block 502. A pin mounting block 503 is mounted on the second transmission block 502, and a pin 504 is mounted on the pin mounting block 503. The second telescopic drive mechanism 501 drives the pin 504 forward, pushing the aligned electronic component 11 towards the positioning part 601. This eliminates any small gaps that may exist in the component after the alignment grippers are released, achieving final precise positioning and ensuring that it does not shift during the cutting process. The second telescopic drive mechanism 501 is a cylinder, providing stable thrust and ensuring the reliability and consistency of the positioning.

[0030] The reference block 6 is mounted on the mounting bracket 9 via the pad 10. The top side of the reference block 6 is provided with a positioning part 601 that is opposite to the ejector pin 504. The electronic component 11 is limited on one side by the fixed positioning part 601 and pushed on the other side by the movable ejector pin 504, thereby ensuring that each component is fixed in the designated position before cutting and ensuring its stability during the cutting process.

[0031] The working process of this utility model is as follows: The operator or robot places the electronic component 11 on the reference block 6. The first telescopic drive mechanism 401 drives the clamping assembly to move towards the reference block 6, and the gripper drive mechanism 407 drives the left gripper 403 and the right gripper 404 to jointly clamp the electronic component 11, so that the electronic component 11 is centered on the reference block 6. Then, the second telescopic drive mechanism 501 drives the ejector pin 504 to move forward, pushing the electronic component 11 to fit against the positioning part 601, completing the precise positioning. Subsequently, the gripper releases and retracts, and the cutting transverse drive mechanism 8 drives the two sets of cutting devices 2 to move relative to each other to the cutting position. The cutting drive mechanism 207 drives the upper cutter 201 and the lower cutter 202 to move synchronously to complete the cutting of the pin 12. The cut waste falls into the collection box 210 and is discharged through the outlet pipe 211. After the cutting device 2 exits, the mechanism resets and enters the next working cycle.
