Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a lead cutting machine for circuit board manufacturing. Background Technology

[0002] Circuit boards are the foundation of electronic products. Commonly used circuit boards include resistors, capacitors, inductors, potentiometers, and transformers. Circuit boards are mainly composed of pads, vias, mounting holes, wires, components, and connectors. However, during the production process of circuit boards, the length of the wires that make up the circuit board is usually slightly longer during installation, which is inconvenient for subsequent use. Therefore, it is necessary to cut off the excess length of the pins on the circuit board.

[0003] The prior art provides a lead-cutting machine for circuit board production (publication number CN219703337U). The two ends of the main rotating shaft and the two ends of multiple auxiliary rotating shafts are all rotating structures with respect to the processing table. The main rotating shaft and auxiliary rotating shafts are connected by belts. The top seat is fixed above the processing table by a support rod. A first motor is provided at the lower end of the top seat. Anti-slip blocks are provided in the middle part of the main rotating shaft and auxiliary rotating shafts. The circuit board to be cut is placed on the processing table, so that the two sides of the circuit board are inside the guide groove. At this time, the anti-slip blocks are squeezed. After the anti-slip blocks rotate, the circuit board can move in the empty groove. When the circuit board passes the cutter, the cutter can cut the lead on one side of the circuit board.

[0004] In actual use, the aforementioned patent involves placing the circuit board on a fixed-size processing table and directly cutting off excess leads with a cutter. However, the cut leads are scattered on the ground due to the lack of a collection structure, which increases the difficulty of subsequent cleaning. At the same time, the fixed worktable cannot flexibly adjust the cutting distance according to the production needs of circuit boards of different sizes, which limits the applicability of the equipment. Therefore, we need to propose a lead cutting machine for circuit board production. Utility Model Content

By setting up an adjustment mechanism and a collection mechanism, the adjustment mechanism can flexibly adjust the distance between the two sets of limit frames according to the size of the circuit board, thereby adapting to the cutting requirements of circuit boards of different sizes.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A lead-cutting machine for circuit board production includes a base plate 1, two sets of support plates 2, a cutter 3, and a U-shaped frame 4. The two sets of support plates 2 are symmetrically fixed on both sides of the base plate 1, and the cutter 3 is installed on the side of the two sets of support plates 2 facing each other. The U-shaped frame 4 is fixedly installed on the top of the two sets of support plates 2. Limiting frames 5 for placing circuit boards are respectively provided on the side of the two sets of support plates 2 facing each other. An adjustment mechanism 6 for adjusting the spacing between the two sets of limiting frames 5 is provided inside the U-shaped frame 4. A collection mechanism 7 for collecting the cut leads is installed on the top of the base plate 1.

[0025] With the setup of a base plate 1, two sets of support plates 2, a cutter 3, a crisscross frame 4, a limiting frame 5, an adjustment mechanism 6, and a collection mechanism 7, the base plate 1 serves as the overall support foundation. Two sets of support plates 2 are symmetrically installed on both sides of the base plate 1 to form a stable frame. The cutter 3 installed inside the support plate 2 can cut off excess pins on the circuit board. The crisscross frame 4 and the adjustment mechanism 6 provide installation space, while the limiting frame 5 is used to place the circuit board. The adjustment mechanism 6 inside the crisscross frame 4 can adjust the distance between the two sets of limiting frames 5 to adapt to the cutting requirements of circuit boards of different sizes. The collection mechanism 7 on the top of the base plate 1 is responsible for collecting the cut pins to prevent them from scattering and to keep the working environment clean.

[0026] The adjusting mechanism 6 includes a motor 61, a bidirectional threaded rod 62, and two sets of moving blocks 63. The motor 61 is fixedly installed on one side of the C-shaped frame 4, and the output end of the motor 61 is fixedly connected to one end of the bidirectional threaded rod 62 through a coupling. The bidirectional threaded rod 62 is rotatably installed inside the C-shaped frame 4. The two sets of moving blocks 63 are respectively threaded to the outside of the bidirectional threaded rod 62, and the bottom of the two sets of moving blocks 63 is respectively fixedly connected to the top of the two sets of limiting frames 5.

[0027] With the configuration of motor 61, bidirectional threaded rod 62 and two sets of moving blocks 63, motor 61 can be a 57 series two-phase hybrid stepper motor. When motor 61 is running, bidirectional threaded rod 62 rotates and drives two sets of moving blocks 63 to move synchronously in opposite directions, thereby driving limit frame 5 to achieve spacing adjustment. The adjustable spacing of limit frame 5 can meet the placement requirements of circuit boards of different sizes, thus greatly improving the versatility of the equipment.

[0028] Specifically, the adjustment mechanism 6 also includes a slider 64 and a slide groove 65; the top of the two sets of moving blocks 63 are respectively fixedly installed with sliders 64, and the inner top of the shaped frame 4 is provided with two sets of slide grooves 65 for the sliders 64 to slide.

[0029] By setting up slider 64 and slide groove 65, slider 64 slides within slide groove 65, restricting the horizontal freedom of moving block 63, so that moving block 63 can only move in a straight line along slide groove 65, effectively preventing moving block 63 from shifting or shaking during movement, ensuring the accuracy and stability of the spacing adjustment of limit frame 5, and thus ensuring the precision of circuit board in the lead cutting process.

[0030] In a further preferred embodiment, the collection mechanism 7 includes a collection box 71, two sets of limiting blocks 72 and two sets of limiting grooves 73; the collection box 71 is installed on the top of the base plate 1 and is located below the cutter 3; the two sets of limiting blocks 72 are symmetrically fixedly installed on the bottom of the collection box 71; and the top of the base plate 1 has two sets of limiting grooves 73 symmetrically arranged for the limiting blocks 72 to engage.

[0031] With the arrangement of the collection box 71, two sets of limiting blocks 72, and two sets of limiting grooves 73, the collection box 71 is installed on the top of the base plate 1 and located below the cutter 3. It can directly receive the pins cut by the cutter 3 and achieve centralized collection. The two sets of limiting blocks 72 symmetrically fixed at the bottom of the collection box 71 are engaged with the two sets of limiting grooves 73 symmetrically opened at the top of the base plate 1. This engagement method not only makes the collection box 71 stable and prevents it from moving or shaking during the collection of pins, but also makes it very convenient to disassemble when the collection box 71 needs to be cleaned. Simply pull the collection box 71 outward to make the limiting blocks 72 disengage from the limiting grooves 73, which facilitates the processing of the collected pins and improves work efficiency.

[0032] Specifically, two sets of sliding rods 8 are symmetrically fixedly installed on the side of the limiting frame 5 near the support plate 2, and two sets of through holes 9 are symmetrically opened inside the support plate 2 for the sliding rods 8 to slide.

[0033] With the sliding rod 8 and the through hole 9, the sliding rod 8 slides in the through hole 9 of the support plate 2, which plays a limiting and guiding role in the movement of the limiting frame 5, ensuring the straightness of the limiting frame 5 when it moves. At the same time, the symmetrically arranged sliding rods 8 ensure the stability of the limiting frame 5 when it moves.

[0034] Among them, a limiting plate 10 is fixedly installed at the end of the slide bar 8 away from the limiting frame 5, and the diameter of the limiting plate 10 is larger than the diameter of the through hole 9.

[0035] By setting the limiting plate 10, the diameter of the limiting plate 10 at the end of the slide rod 8 is larger than that of the through hole 9, forming a mechanical limit, which can prevent the slide rod 8 from accidentally coming out.

[0036] Specifically, the inner bottom and inner top of the limiting frame 5 are provided with multiple sets of balls 11, and the multiple sets of balls 11 are arranged in a rectangular array.

[0037] With the setting of the ball bearing 11, when the circuit board is pushed, the circuit board contacts the ball bearing 11. The rolling characteristics of the ball bearing 11 allow the circuit board to slide easily within the limit frame 5, making the operation more convenient and labor-saving. At the same time, it reduces the scratches or damage that may be caused by friction on the surface of the circuit board, ensuring the quality of the circuit board and improving the efficiency and quality of the cutting operation.

[0038] The bottom inner part of the limiting frame 5 is provided with a groove 12 for the cutter 3 to pass through.

[0039] By setting the groove 12, during the adjustment of the limiting frame 5, the groove 12 can avoid direct contact and friction between it and the cutter 3, effectively preventing damage to the cutting edge of the cutter 3 and wear on the surface of the limiting frame 5, and extending the service life of both.

[0040] Working principle: When using this utility model, firstly, start the motor 61 according to the size of the circuit board to be processed. The motor 61 drives the bidirectional threaded rod 62 to rotate through the coupling, which drives the two sets of moving blocks 63 to move synchronously in opposite directions along the slide groove 65, thereby accurately adjusting the working distance of the limit frames 5 on both sides.

[0041] After adjustment, the circuit board is placed in the limiting frame 5. With the assistance of the ball bearing 11, the circuit board can be easily moved. The cutter 3 precisely cuts the protruding pins of the circuit board. The cut pins fall into the collection box 71 below under the action of gravity for centralized recycling. The collection box 71 is easy to disassemble and assemble through the quick-connect structure between the bottom limiting block 72 and the limiting groove 73 of the bottom plate 1, which facilitates regular cleaning and maintenance.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
