Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a circuit board lead trimming machine. Background Technology

[0002] In the circuit board manufacturing process, to meet installation requirements, long leads are usually reserved at the edge of the board. These leads need to be trimmed before subsequent assembly. Traditional trimming methods mostly rely on manual operation or fixed fixtures, which are inefficient and have poor precision. At the same time, due to the diverse sizes and specifications of circuit boards, existing equipment cannot quickly adapt to boards of different widths, resulting in cumbersome adjustments, limited applicability, and affecting overall processing efficiency and quality. Utility Model Content

[0003] To solve the above problems, this technical solution provides a circuit board lead cutting machine.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A circuit board lead trimming machine, comprising

[0006] A frame on which a motor is mounted, and a mounting base located on the output end of the motor for fixing the saw blade;

[0007] The feeding mechanism includes a first longitudinal rail and a second longitudinal rail, and a first slide groove and a second slide groove respectively disposed on the first longitudinal rail and the second longitudinal rail; an installation space for placing a circuit board is formed between the first slide groove and the second slide groove; the first slide groove and the second slide groove are used to support the circuit board and allow the circuit board to slide towards the fixed base;

[0008] The adjusting mechanism includes a first movable seat located at both ends of the first longitudinal rail, a second movable seat located at both ends of the second longitudinal rail, and a lead screw threadedly engaged with the first movable seat and the second movable seat; the lead screw rotates to bring the first movable seat and the second movable seat closer to or further away from each other, thereby reducing or increasing the width of the installation space.

[0009] The circuit board lead cutting machine described above further includes a synchronization mechanism, which includes a drive wheel and a hand crank on one end of the lead screw, and a driven wheel on the other end of the lead screw. The drive wheel and the driven wheel are driven by a belt, so that the hand crank simultaneously drives the two lead screws to rotate.

[0010] As described above, in a circuit board lead trimming machine, the synchronization mechanism further includes an adjusting wheel mounted on the frame, wherein the adjusting wheel, the driving wheel, and the driven wheel jointly adjust the tension of the belt.

[0011] As described above, in a circuit board lead cutting machine, a material collection tray is provided below the feeding mechanism, and a material outlet is provided on the material collection tray. The material collection tray is used to collect and guide the leads that have been cut to be discharged to the material outlet.

[0012] The circuit board lead trimming machine described above also includes a shaking mechanism for shaking the collection tray so that the leads are discharged from the outlet.

[0013] As described above, a circuit board lead trimming machine includes a vibrating disc mechanism comprising a pressure block disposed on the first movable seat and the second movable seat, a wave-shaped protrusion disposed on the collection disc, and an elastic support leg disposed between the frame and the collection disc. When the first movable seat and the second movable seat move, they drive the pressure block to press against the protrusion, thereby causing the collection disc to vibrate up and down repeatedly.

[0014] As described above, in a circuit board lead trimming machine, the elastic support includes a main support on the frame, a secondary support sleeved on the main support and connected to the collection tray, and a spring between the main support and the secondary support.

[0019] Figure 2 yes Figure 1 A sectional view. Detailed Implementation

[0020] To make the technical problems solved, technical solutions, and beneficial effects 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.

[0021] A circuit board lead trimming machine, comprising

[0022] A frame 1 is provided with a motor 11 and a mounting base 12 located on the output end of the motor 11 for fixing the saw blade.

[0023] The feeding mechanism 2 includes a first longitudinal rail 21 and a second longitudinal rail 22, and a first slide groove 23 and a second slide groove 24 respectively disposed on the first longitudinal rail 21 and the second longitudinal rail 22; an installation space 25 for placing the circuit board is formed between the first slide groove 23 and the second slide groove 24; the first slide groove 23 and the second slide groove 24 are used to support the circuit board 7 and allow the circuit board to slide towards the fixed base 12;

[0024] The adjusting mechanism 3 includes a first movable seat 31 located at both ends of the first longitudinal rail 21, a second movable seat 32 located at both ends of the second longitudinal rail 22, and a lead screw 33 threadedly engaged with the first movable seat 31 and the second movable seat 32; the lead screw 33 rotates to bring the first movable seat 31 and the second movable seat 32 closer to or further away from each other, thereby reducing or increasing the width of the installation space 25.

[0025] This utility model provides a circuit board lead cutting machine that precisely and smoothly adjusts the distance between the first and second longitudinal rails through a lead screw drive, enabling it to quickly adapt to circuit boards of different widths. It is highly versatile and ensures the stability and centering of the circuit board during the cutting process.

[0026] Furthermore, as a preferred embodiment of this solution, and not a limitation thereof, a synchronization mechanism 4 is also included. This mechanism includes a drive wheel 41 and a hand crank 42 located at the end of one of the lead screws 33, and a driven wheel 43 located at the end of the other lead screw 33. The drive wheel 41 and the driven wheel 43 are driven by a belt, so that the hand crank 42 simultaneously drives both lead screws 33 to rotate. By using a single hand crank, the lead screws on both sides can be driven synchronously, ensuring the synchronous opposite or reciprocating movement of the first and second longitudinal rails. This avoids problems such as jamming or track misalignment during adjustment, making the width adjustment operation simpler and more reliable.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, the synchronization mechanism 4 also includes an adjusting wheel 44 mounted on the frame 1. The adjusting wheel 44, the driving wheel 41, and the driven wheel 43 jointly adjust the belt tension. By maintaining appropriate belt tension through the adjusting wheel, slippage or detachment of the belt during transmission is effectively prevented, ensuring the reliability and stability of the synchronization mechanism transmission, thereby guaranteeing the accuracy of the pitch adjustment process.

[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, a collection tray 5 is provided below the feeding mechanism 2, and the collection tray 5 is provided with a discharge port 51. The collection tray 5 is used to collect and guide the metal leads cut by the magnetic cutting to be discharged through the discharge port 51. This can collect the metal leads generated during the cutting process and discharge them centrally through the discharge port, avoiding the leads from scattering inside the equipment or in the working area, facilitating cleaning and recycling, maintaining a clean working environment, and reducing safety hazards.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, a shaking mechanism 6 is also included, which is used to shake the collection tray 5 so that the pins are discharged from the discharge port 51. By shaking the collection tray, small pins can be prevented from accumulating in the tray or blocking the discharge port, promoting the smooth movement of the pins towards the discharge port and their discharge, realizing automatic and continuous cleaning of the pins and reducing manual intervention.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the shaking mechanism 6 includes a pressure block 61 disposed on the first movable seat 31 and the second movable seat 32, a wave-shaped protrusion 62 disposed on the collection tray 5, and an elastic support leg disposed between the frame 1 and the collection tray 5. When the first movable seat 31 and the second movable seat 32 move, they drive the pressure block 61 to press against the protrusion 62, thereby causing the collection tray 5 to vibrate up and down reciprocally. The movement of the adjusting mechanism itself is cleverly utilized as a power source. When the movable seat moves, the pressure block and the wave-shaped protrusion interact, and in conjunction with the elastic support leg, convert the horizontal movement into the up and down vibration of the collection tray. This design requires no additional power unit, has a simple and compact structure, and achieves the linkage between the adjusting distance and the cleaning function, making it energy-saving and highly efficient.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the elastic support includes a main support 63 mounted on the frame 1, a secondary support 64 sleeved on the main support 63 and connected to the collection tray 5, and a spring 65 between the main support 63 and the secondary support 64. This elastic support structure not only provides stable elastic support for the collection tray, allowing it to vibrate smoothly up and down, but also reduces the impact of vibration on the frame due to the buffering effect of the spring, improving the stability of equipment operation and service life.

[0032] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
