[0002] Surface mount technology, or SMT for short, as a new generation of electronic assembly technology has penetrated into various fields. SMT products have the advantages of compact structure, small size, vibration resistance, shock resistance, good high-frequency characteristics, and high production efficiency. SMT has taken a leading position in the circuit board assembly process. Pins refer to the wiring from the internal circuit of the integrated circuit (chip) to the peripheral circuit. The pins constitute the interface of this chip. According to the function, the pins of AT89S52 can be divided into four categories: main power supply, external crystal or oscillator, multi-function I / O port, and control, strobe and reset.

[0003] In the process of processing some electronic circuit components, the circuit pins of some electronic components are relatively long during production. Due to the design of different circuit boards, when using universal electronic components, the length of the pins may not completely match the circuit board, so cutting is required. The existing processing equipment is generally large and cannot be used for convenient operation and shearing tests. In addition, it cannot be replaced to cut different electronic components. Based on this, we propose a universal small trimming machine for surface mount circuit pin size control. Utility Model Content

[0020] The working principle of the above technical solution is as follows: when in use, the user places the electronic components to be trimmed on the top of the cutting bottom mold 17, and then holds the pressure rod 11 and pulls it down, slides on the outside of the pressure rod 11 through the movable ring 13, and drives the hinged rotating connecting ring 12 to move, and applies a downward force to the top of the pressure plate 16 through the connecting ring 12, and drives the cutting top mold 21 to move downward through the pressure plate 16 to match the cutting bottom mold 17, and cuts off the pins exposed on the outside of the cutting bottom mold 17. After cutting, release the pressure rod 11, and the pressure plate 16 rebounds and resets under the action of the telescopic rod 14 and the spring 15.

[0021] In another embodiment, Figure 1-Figure 4 As shown, the top end of the spring 15 is fixedly mounted on the bottom of the top plate 8 , and the bottom end of the spring 15 is fixedly mounted on the top of the pressure plate 16 .

[0022] The spring 15 is the telescopic rod 14 and the outer elastic force is convenient to cooperate with the telescopic rod 14 to form a stable elastic force, which is convenient for auxiliary operation and makes the overall structure stable.

[0023] In another embodiment, Figure 1-Figure 4 As shown, the pressure plate 16 is movably sleeved on the outer side of the sliding column 4.

[0024] The pressing plate 16 slides under the limit of the sliding column 4, so that the pressing plate 16 can slide along the predetermined track of the sliding column 4, which is convenient for stabilizing and balancing the structural moment.

[0025] In another embodiment, Figure 1-Figure 4 As shown, the four second magnetic rings 19 are all movably sleeved on the outside of the sliding column 4, the four first magnetic rings 5 ​​are all sleeved on the outside of the sliding column 4, and the opposite sides of the first magnetic rings 5 ​​and the second magnetic rings 19 are arranged in the same level and repel each other.

[0026] When the first magnetic ring 5 and the second magnetic ring 19 move downward on the pressure plate 16, the repulsive force between the first magnetic ring 5 and the second magnetic ring 19 rebounds, adding a reverse elastic force to avoid rigid collision, thereby indirectly protecting the stability of the cutting bottom mold 17 and the cutting top mold 21 when cutting pins.

[0027] In another embodiment, Figure 1-Figure 4 As shown, the specifications and dimensions of the cutting bottom mold 17 are compatible with the specifications and dimensions of the mounting grooves 6 , the specifications and dimensions of the cutting bottom mold 17 are compatible with the specifications and dimensions of the cutting top mold 21 , and the number and positions of the mounting grooves 6 correspond to the number and positions of the mounting plates 20 .

[0029] In another embodiment, Figure 1-Figure 4 As shown, the connecting ring 12 is movably sleeved on the outer side of the sliding column 4.

[0030] The connecting ring 12 slides outside the sliding column 4 to facilitate the transmission of the downward force of the movable ring 13, thereby stabilizing the moment of the steel structure and making the overall structure stable.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
