Description

Technical Field

[0002] With the development of science and technology, the improvement of electronic technology, and the miniaturization of electronic products, the further improvement of performance and reliability, electronic components have developed from large, heavy and thick to small, light and thin, and chip components and surface mounting technology have emerged. Chip electronic components are new types of tiny components without leads or with short leads.

[0003] When making chip electronic components, it is necessary to first place the electronic component patches into the mold holes of the printing template, and then drip solder paste into the mold holes to solder the patches together to make chip electronic components. After the electronic components are made, the excess solder paste on their surfaces needs to be cut off. Currently, the cutting work is done by handheld knives. The handheld knives cannot ensure that the cutters always keep horizontal movement during cutting, which easily leads to uneven cutting of the component surface, making the quality of the manufactured chip electronic components poor. To this end, we provide a chip electronic component printing template. Utility Model Content

[0024] A fixing groove 11 is provided between the inner and outer walls on the right side of the fixing frame 1 , and sliding grooves 12 are provided on both the left and right sides of the inner wall of the fixing frame 1 .

[0025] Specifically, the inner cavity of the fixed groove 11 is provided with a ball screw 5, and the ball screw 5 includes a threaded rod 51. The outer ring of the threaded rod 51 is provided with a movable nut 52. The back of the threaded rod 51 is rotatably connected to the back of the inner wall of the fixed groove 11. The front of the threaded rod 51 passes through the front of the inner wall of the fixed groove 11 and is provided with a crank 8. When in use, the crank 8 is turned clockwise to drive the threaded rod 51 to rotate clockwise to make the movable nut 52 move forward. If the crank 8 is turned counterclockwise, the threaded rod 51 can be driven to rotate counterclockwise to make the movable nut 52 move backward.

[0026] Furthermore, a cutter 4 is provided on the top of the printed board 2, and a slide bar 41 is provided on the left and right sides of the cutter 4. The slide bar 41 is slidably engaged in the inner cavity of the slide groove 12, and the slide bar 41 corresponds to the slide groove 12 one by one. The right side of the slide bar 41 on the right side passes through the right side of the inner wall of the slide groove 12 and is fixedly connected to the left side of the movable nut 52. After the chip electronic components are welded, the crank 8 can be rotated to drive the threaded rod 51 to rotate along the pointer and move the movable nut 52 forward. At the same time, the slide bar 41 slides back and forth in the slide groove 12, which can drive the cutter 4 to move back and forth. The cutter 4 can cut off the excess solder paste overflowing the mold hole 21 to keep the surface of the electronic components smooth.

[0027] Specifically, a base plate 3 is provided directly below the fixed frame 1, and a plurality of top blocks 31 are provided on the top of the base plate 3. The top of the top block 31 fits with the bottom of the mold hole 21, and the top block 31 corresponds to the mold hole 21 one by one. After the excess solder paste on the surface of the chip electronic component is cut off, the fixed frame 1 can be pushed downward. At this time, the top block 31 is inserted upward into the mold hole 21 to eject the electronic components therein. This structure can eject all the electronic components at the same time, which not only saves time and effort, but also improves the production efficiency of electronic components.

[0028] Furthermore, support rods 6 are provided at the four corners of the bottom of the fixed frame 1, the bottom of the support rods 6 passes through the top of the bottom plate 3, the outer ring of the support rods 6 is provided with a spring 7, the top of the spring 7 is fixedly connected to the bottom of the fixed frame 1, and the bottom of the spring 7 is fixedly connected to the top of the bottom plate 3.

After the electronic components are ejected, the fixed frame 1 is released, the spring 7 returns to its original state and drives the fixed frame 1 to move upward. At this time, the ejection block 31 returns to the bottom of the mold hole 21. During this process, the support rods 6 can keep the fixed frame 1 moving smoothly.
