Description

Technical Field

[0001] This utility model relates to the field of electronic device processing equipment technology, and in particular to an auxiliary cutting device for bridge-type electronic components. Background Technology

[0002] Bridge-type electronic components (such as bridge rectifiers) are fundamental power conversion elements widely used in various power modules and printed circuit boards (PCBs). These components typically come with relatively long standard leads to meet common mounting and heat dissipation requirements. However, in practical applications, different customers have significantly different PCB designs, with specific requirements for component mounting height, lead extension length, and molding style; therefore, the leads usually need to be customized according to customer specifications.

[0003] The common practice in the industry is that after components are marked with machine markings (i.e., laser marking or ink printing), operators manually shape and trim the leads. However, this method heavily relies on the operator's skill level and is inefficient, making it unsuitable for large-scale order fulfillment. Furthermore, manual trimming can easily lead to inconsistent lead lengths, affecting quality. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary lead-cutting device for bridge electronic components, which solves the technical problem of low lead-cutting efficiency in existing bridge electronic components.

[0005] This application discloses an auxiliary lead-cutting device for bridge electronic components, comprising: Workbench; A guide plate is installed on the workbench, and the guide plate is provided with shearing holes; A shearing mechanism is mounted on the worktable, and the direction of movement of the shearing mechanism is perpendicular to the guide plate, with the shearing end of the shearing mechanism facing the shearing hole; A clamping mechanism is mounted on the worktable, and the clamping end of the clamping mechanism cooperates with the guide plate; The clamping mechanism includes: Two clamping cylinders are respectively disposed on both sides of the guide plate; Two clamping plates are installed one-to-one on the piston rod end of the clamping cylinder, and multiple clamping slots are provided on the clamping plates.

[0006] This application includes a cutting mechanism and a clamping mechanism. The clamping mechanism and the cutting mechanism work together to remove the pins while ensuring the quality of the pin removal.

[0007] Based on the above technical solution, the present application can be further improved as follows: Furthermore, the shearing mechanism includes: Two shearing cylinders are installed at intervals on the worktable, and the shearing cylinders are located on both sides of the guide plate; Two cutters are installed one-to-one on the piston rod end of the shearing cylinder, and the cutters correspond to the shearing holes. The advantage of this step is that the shearing cylinder and the cutters work together to achieve stable cutting of the pin.

[0008] Furthermore, the clamping mechanism includes: Two sliding tables are installed at intervals on the worktable, and the sliding direction of the sliding tables is parallel to the guide plate. The sliding tables are located on both sides of the guide plate. The connecting plate has two ends connected to the movable ends of the slide table; A support plate is installed on the movable end of the slide, and the clamping cylinder is installed on the support plate. The advantage of this step is that the connecting plate and the slide can move back and forth, and the position of the clamping cylinder can be adjusted by combining the support plate.

[0009] Furthermore, the clamping mechanism also includes: A limiting plate is installed at the output end of any of the clamping cylinders, and the limiting plate moves away from or towards the guide plate under the drive of the clamping cylinder. The limiting plate has multiple limiting grooves on the side facing the guide plate. The advantage of this step is that the bridge electronic component can be clamped by the limiting plate, which facilitates the subsequent adjustment of the position of the bridge electronic component.

[0010] Furthermore, the limiting plate is located above the clamping plate. The advantage of this step is that by adjusting the position of the limiting plate, the clamping positions of the clamping plate and the limiting plate can be distinguished.

[0011] Furthermore, it also includes a cam mechanism, which is mounted on the worktable and the output end of the cam mechanism cooperates with the connecting plate. A spring is installed on the sliding guide column of the slide table, and the spring is used to realize the reset of the connecting plate. The beneficial effect of this step is that the reciprocating motion of the clamping mechanism can be realized by the cooperation of the cam mechanism and the spring.

These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "setup," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1: like Figure 1-2 As shown in the embodiment of this application, an auxiliary lead-cutting device for bridge electronic components is disclosed to cut the leads of bridge electronic components. Specifically, the device is clamped by a clamping mechanism and then pushed along a guide plate until it reaches the cutting hole to complete the lead cutting. After the cutting is completed, the bridge electronic component is transported to the next area.

[0021] The specific structure of this application includes: Workbench 1, which is an existing workbench on which other structures are integrated; A guide plate 2 is mounted on the workbench 1, and a shearing hole 3 is provided on the guide plate 2 to facilitate subsequent pin cutting. The two ends of the guide plate 2 are connected by mounting bases, so that there is a gap between the bottom surface of the guide plate 2 and the top surface of the workbench 1. This facilitates the installation of the subsequent shearing mechanism 4 and also avoids the pins of the bridge electronic component from contacting the upper surface of the workbench. The bridge electronic component moves along the guide plate 2, that is, the top of the bridge electronic component is located on the guide plate 2, and the pins are located on both sides of the guide plate 2. The shearing mechanism 4 is installed on the workbench 1, and the movement direction of the shearing mechanism 4 is perpendicular to the guide plate 2. The shearing end of the shearing mechanism 4 faces the shearing hole 3. When the pin moves to the shearing hole 3, the shearing mechanism 4 moves to complete the cutting off of the pin. A clamping mechanism 5 is installed on the workbench 1, and the clamping end of the clamping mechanism 5 cooperates with the guide plate 2. The clamping mechanism 5 is used to clamp and limit the pin, so that the cutting mechanism 4 can complete the pin cutting. The clamping mechanism 5 includes: Two clamping cylinders 501 are respectively disposed on both sides of the guide plate 2; Two clamping plates 502 are installed one-to-one with the piston rod end of the clamping cylinder 501, and multiple clamping slots 503 are provided on the clamping plates 502; the clamping mechanism 5 in this application only needs to include two power components to realize opposite movement, thereby completing the opposite clamping of the pins. At the same time, the clamping slots 503 can complete the clamping of the pins, which facilitates the limiting and thus completes the cutting off of the pins.

[0022] To ensure stability during shearing, this application designs a shearing mechanism 4, wherein the shearing mechanism 4 includes: Two shearing cylinders 401 are installed at intervals on the worktable 1, and the shearing cylinders 401 are located on both sides of the guide plate 2; Two cutters 402 are installed one-to-one with the piston rod end of the shearing cylinder 401, and the cutters 402 correspond to the shearing holes 3. This application provides two shearing cylinders 401, which are spaced apart. By using the opposite arrangement of the shearing cylinders 401, the opposite movement of the piston rods pushes the cutters 402 to move in opposite directions. Since the cutters 402 correspond to the shearing holes 3, the pins can be cut off.

[0023] The clamping mechanism 5 in this application not only has a clamping function, but also drives the bridge electronic component to move along the guide plate 2 during the clamping process. This movement extends beyond the shearing point; after shearing, the component is transported to the next area. Specifically, the clamping mechanism 5 includes: Two slides 504 are installed at intervals on the worktable 1, and the sliding direction of the slides 504 is parallel to the guide plate 2. The slides 504 are located on both sides of the guide plate 2. Each slide 504 includes a sliding guide post and a slider. The sliding guide post is parallel to the guide plate 2, and the slide 504 can slide along the sliding guide post, thereby realizing the sliding of the slider (the movable end of the slide 504 refers to the slider). A connecting plate 505 is installed on the movable end (slider) of the slide table 504, and the connecting plate 505 subsequently cooperates with the cam mechanism. A support plate 509 is installed on the movable end (slider) of the slide table 504, and the clamping cylinder 501 is installed on the support plate 509. The clamping mechanism 5 in this application includes a sliding part, that is, the movement of the connecting plate 505 drives the slide table 504 to move, thereby driving the support plate 509 to move, which in turn drives the clamping cylinder 501 to move. The direction of movement is parallel to the guide plate 2, so that after clamping the bridge electronic component, it can continue to move along the guide plate 2.

[0024] To achieve stable movement of the bridge electronic components, the clamping mechanism 5 further includes: A limiting plate 506 is installed at the output end of any of the clamping cylinders 501, and the limiting plate 506 moves away from or towards the guide plate 2 under the drive of the clamping cylinders 501. The limiting plate 506 has multiple limiting grooves 507 on the side facing the guide plate 2. The limiting plate 506 and one of the clamping plates 502 move synchronously to achieve clamping and limiting of the bridge electronic component. When the slide table 504 is pushed to move, it can drive the connecting plate 505 to move, thereby driving the electronic component to move along the guide plate 2.

[0025] In order for the limiting plate 506 to hold the top of the bridge electronic component, the limiting plate 506 is located above the clamping plate 502, so that the clamping plate 502 can hold the bottom of the bridge electronic component.

[0026] The slide table 504 in this application can be driven by a cylinder or by a cam mechanism 6. That is, this application also includes a cam mechanism 6. The cam mechanism 6 is mounted on the worktable 1, and the output end of the cam mechanism 6 cooperates with the connecting plate 505. A spring 508 is installed on the sliding guide column of the slide table, and the spring 508 is used to reset the connecting plate 505.

[0027] Specifically, the cam mechanism 6 includes a drive motor and a cam. The drive motor is installed inside the worktable 1, and the cam is installed at the output end of the drive motor. At the same time, the outer edge of the cam contacts the connecting plate 505, pushing the connecting plate 505 to move downward, while the spring pushes the connecting plate 505 to move upward, so as to realize the reset of the slide table, thereby realizing the reciprocating motion of the clamping mechanism 5.

[0028] Further explanation is provided regarding this application: This application is for implementing a lead-cutting aid for bridge electronic components, which can be installed on a continuous processing machine for easy processing.

[0029] During processing, the bridge-type electronic component slides down along the guide plate 2. After reaching the corresponding position, the clamping mechanism 5 performs processing. At this time, the clamping groove 503 clamps the pin portion, and the limiting plate 506 limits the top of the electronic component. Driven by the cam mechanism 6, the electronic component can move down along the guide plate 2 until the pin moves to the shearing hole 3. Then the cutter moves toward the shearing hole 3 to complete the cutting of the pin. Then the cam mechanism continues to move, moving the electronic component down along the guide plate 2 until it leaves the guide plate 2.
