Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and more specifically, to a circuit board manufacturing lead trimming device. Background Technology

[0002] Circuit boards are important electronic components, serving as the support for electronic components and the carrier for electrical connections. Manufactured using electronic printing techniques, they enable miniaturization and visualization of circuits, playing a crucial role in the mass production of fixed circuits and the optimization of electrical layout. After the integrated circuit board is soldered, a pin trimming process is required.

[0003] A search revealed a circuit board production lead-cutting device disclosed in Chinese Patent Publication No. CN 217591232 U. Although the device uses a first electric push rod to clamp the circuit board body with an elastic L-plate to prevent shaking, and a limiting plate to prevent the slip ring from falling off, and a third electric push rod to push the slide block to slide on the slide rod for lateral movement and cutting, this device cannot continuously cut leads on multiple circuit boards, increasing the amount of repetitive operation in the circuit board lead-cutting work, resulting in a relatively slow overall process speed and affecting the efficiency of circuit board lead-cutting. Based on this, this utility model designs a circuit board production lead-cutting device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board manufacturing lead-cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circuit board production lead-cutting device includes a workbench, a material holder, a top seat, and several pressure blocks. The material holder is fixedly mounted on the workbench via a lower column. The surface of the material holder has several equidistant grooves corresponding to the pressure blocks in a ring shape. The bottom of each groove has an opening. The top seat is fixedly mounted on the material holder via an upper column. A telescopic cylinder is fixedly mounted on the upper end of the top seat. A lifting seat is fixedly mounted on the telescopic end of the telescopic cylinder. An elastic component is provided between the lifting seat and the pressure blocks. A rotating shaft is rotatably connected to the workbench directly below the material holder. A carrier frame is fixedly mounted on the upper end of the rotating shaft. A shearing component is provided on one side of the carrier frame. An electric push rod is fixedly mounted on the right side of the workbench. A rack is fixedly mounted on the telescopic end of the electric push rod via a transmission seat. A toothed ring is fixedly sleeved on the outside of the rotating shaft. The rack meshes with the toothed ring.

[0008] As a preferred embodiment of this utility model, the shearing assembly includes a motor and a shearing blade. The motor is fixedly mounted on a carrier, and the shearing blade is fixedly connected to the drive shaft of the motor.

[0009] As a preferred embodiment of this utility model, a control panel is fixedly installed on the left side of the workbench, and the output end of the control panel is electrically connected to the input end of the telescopic cylinder, the electric push rod, and the motor.

[0010] As a preferred technical solution of this utility model, a guide block is fixedly connected to the side of the lifting seat, and the guide block is slidably sleeved on the outside of the upper column.

[0011] As a preferred embodiment of this utility model, the upper end of the loading groove is provided with a material taking groove on both sides, and the cross-sectional shape of the material taking groove is rectangular.

[0012] As a preferred embodiment of this utility model, a crossbar is fixedly installed on the workbench, and the transmission seat is slidably sleeved on the outside of the crossbar.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention involves placing circuit boards sequentially into the corresponding slots of a material holder, exposing the leads to be cut through the openings. A telescopic cylinder drives a lifting seat to descend, causing pressure blocks to press against the respective circuit boards. Springs contract, clamping and limiting the circuit boards in the slots. An electric push rod drives a rack to move, causing the rotating shaft and carrier to rotate one revolution. Simultaneously, the shearing assembly rotates, and a motor drives the shearing blades to rotate, allowing the shearing assembly to sequentially cut the leads of each circuit board. This facilitates continuous lead cutting of multiple circuit boards, reducing repetitive operations and accelerating the overall process, thus improving the efficiency of circuit board lead cutting.

[0020] 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.

[0021] like Figures 1 to 4 As shown, this utility model provides a circuit board lead trimming device, including a workbench 1, a material holder 2, a top seat 3, and several pressure blocks 5. The material holder 2 is fixedly installed on the workbench 1 by a lower column 101. The surface of the material holder 2 is provided with several loading grooves 201 corresponding to the pressure blocks 5 in an annular pattern. The bottom of the loading grooves 201 is provided with an opening 202. The top seat 3 is fixedly installed on the material holder 2 by an upper column 301. A telescopic cylinder 302 is fixedly installed on the upper end of the top seat 3. A lifting seat 4 is fixedly installed on the telescopic end of the telescopic cylinder 302. An elastic component is provided between the lifting seat 4 and the pressure blocks 5. 6. A rotating shaft 102 is rotatably connected to the workbench 1 directly below the material holder 2. A carrier frame 103 is fixedly installed on the upper end of the rotating shaft 102. A shearing assembly 7 is provided on one side of the carrier frame 103. An electric push rod 8 is fixedly installed on the right side of the workbench 1. A rack 802 is fixedly installed on the telescopic end of the electric push rod 8 through a transmission seat 801. A toothed ring 104 is fixedly sleeved on the outside of the rotating shaft 102. The rack 802 meshes with the toothed ring 104, so that when the electric push rod 8 drives the rack 802 to move, it can drive the rotating shaft 102 and the carrier frame 103 to rotate. At the same time, the shearing assembly 7 rotates accordingly.

[0022] Among them, such as Figure 2 As shown, the elastic component 6 includes a guide rod 601 and a spring 602. The guide rod 601 slides through the lifting seat 4, and the spring 602 is fixedly connected between the lifting seat 4 and the pressure block 5.

[0023] Among them, such as Figure 3 As shown, the shearing assembly 7 includes a motor 701 and a shearing blade 702. The motor 701 is fixedly mounted on the carrier 103, and the shearing blade 702 is fixedly connected to the drive shaft of the motor 701.

[0024] Among them, such as Figure 2 As shown, a control panel 105 is fixedly installed on the left side of the workbench 1. The output end of the control panel 105 is electrically connected to the input end of the telescopic cylinder 302, the electric push rod 8 and the motor 701.

[0025] Among them, such as Figure 3 As shown, a guide block 401 is fixedly connected to the surface of the lifting seat 4. The guide block 401 is slidably sleeved on the outside of the upper column 301, which achieves the purpose of providing a good guiding effect for the lifting seat 4.

[0026] Among them, such as Figure 4 As shown, material picking slots 203 are provided on both sides of the upper end of the carrier slot 201. The cross-sectional shape of the material picking slot 203 is rectangular, which facilitates the picking and placing of the circuit board 9 in the carrier slot 201.

[0027] Among them, such as Figure 4 As shown, a crossbar 106 is fixedly installed on the workbench 1, and the transmission seat 801 is slidably sleeved on the outside of the crossbar 106, which achieves the purpose of providing a good guiding effect for the transmission seat 801.

[0028] The working principle of this utility model:

[0029] During use, circuit boards 9 are placed sequentially into the corresponding slots 201 of the material holder 2, so that the pins to be cut on the circuit boards 9 are exposed through the openings 202. The telescopic cylinder 302 drives the lifting seat 4 to descend, causing the pressure block 5 to press against each circuit board 9. The spring 602 contracts, and the circuit boards 9 in the slots 201 are pressed and limited. The electric push rod 8 drives the rack 802 to move to one side, causing the rotating shaft 102 and the carrier 103 to rotate one revolution in the forward direction. At the same time, the shearing assembly 7 rotates accordingly, and the motor 701 drives the shearing blade 702 to rotate, so that the shearing assembly 7 can sequentially cut off the pins of each circuit board 9, completing the cutting of multiple circuit boards 9. After continuous lead cutting is completed, the lifting seat 4 is raised and reset using the telescopic cylinder 302 to remove the circuit board 9. The next batch of circuit boards 9 are then placed in the corresponding slots 201 of the material holder 2, so that the leads to be cut off on the circuit board 9 are exposed through the through-hole 202. The lifting seat 4 is lowered using the telescopic cylinder 302, and the circuit boards 9 in the slots 201 are pressed and limited. The rack 802 is moved to the other side and reset using the electric push rod 8, which causes the rotating shaft 102 and the carrier 103 to rotate in opposite directions for one revolution. At the same time, the cutting component 7 rotates accordingly, so that the cutting component 7 can cut off the leads of each circuit board 9 in sequence. The circuit board 9 is then removed, and the above operation is repeated.
