Description

Technical Field

[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout.

[0003] During the processing of circuit boards, a series of processing processes such as drilling, developing, stamping, testing and trepanning are required to complete the processing of the circuit boards.

[0004] When trepanning a circuit board, the circuit board is moved to the bottom of the trepanning die by a transmission mechanism, and the circuit board is pushed into contact with the trepanning die by a cylinder to perform trepanning. In the prior art, the position of the circuit board is transmitted to the specified position by a transmission mechanism, and the program sets the moving distance to position the circuit board. During the transmission of the circuit board, if the circuit board shakes, it will cause a deviation between the circuit board and the trepanning die. When the deviation is large, the trepanning will fail, causing damage to the circuit board, resulting in an increase in the processing defect rate, which is not conducive to online production. Therefore, we propose a feeding and receiving device for automatic alignment of circuit boards. Utility Model Content

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] The embodiment of the present application provides a feeding and receiving device for automatic alignment of circuit boards, which solves the problem that when the circuit board shakes during the transmission of the circuit board by the transmission mechanism 4, it will cause deviation between the circuit board and the trepanning die 301. When the deviation is large, it will cause trepanning failure, resulting in damage to the circuit board and an increase in the processing defect rate. The embodiment of the present application solves the problem that the circuit board is placed on the placement seat 5, and when the placement seat 5 drives the circuit board to move upward and contact the trepanning die 301, the circuit board is trepanned. When the placement seat 5 moves upward, it drives the extrusion seat 6 and the positioning seat 601 to move toward each other, contact and extrude the circuit board for positioning, and align the circuit board, so that the trepanning die 301 can easily trepan the circuit board, thereby avoiding inaccurate positioning and the increase in the processing defect rate.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] The embodiment of the utility model discloses a feeding and receiving device for automatic alignment of circuit boards.

[0028] According to the attached Figure 1-5 As shown, it includes an automatic trepanning machine 1, a transmission mechanism 4 is installed inside the automatic trepanning machine 1, and the transmission mechanism 4 is used to drive the circuit board for transmission. A support frame 3 is installed inside the automatic trepanning machine 1, and a trepanning mold 301 is slidably connected to the support frame 3. A placement seat 5 is provided directly below the trepanning mold 301, and the placement seat 5 is provided with:

[0029] Two groups of positioning units, the positioning unit includes an extrusion seat 6 and multiple positioning seats 601, the positioning seat 601 is fixedly connected to the extrusion seat 6, the extrusion seat 6 is slidably connected to the placement seat 5, and the positioning unit positions the circuit board through the extrusion seat 6 and the positioning seat 601, by placing the circuit board on the placement seat 5, when the placement seat 5 drives the circuit board to move upward and contact the hole-making mold 301, the circuit board is holed, and when the placement seat 5 moves upward, it drives the extrusion seat 6 and the positioning seat 601 to move toward each other, contact and extrude the circuit board for positioning, and align the circuit board, so that the hole-making mold 301 can make holes on the circuit board, avoiding inaccurate positioning and increasing the processing defect rate.

[0030] The main cover plate 2 and the side cover plate 201 are rotatably connected to the automatic trepanning machine 1. By opening the main cover plate 2 and the side cover plate 201, the trepanning process can be observed.

[0031] A cylinder 501 is installed inside the automatic trepanning machine 1. The output end of the cylinder 501 is fixedly connected to the placement seat 5. The cylinder 501 is started to drive the placement seat 5 to move upward, so that the placement seat 5 pushes the circuit board to contact the trepanning mold 301 for trepanning.

[0032] A positioning frame 302 is provided above the placement seat 5 , and the positioning frame 302 is fixedly connected to the bottom end surface of the hole forming die 301 .

[0033] A sliding rod 603 is slidably connected to the inner wall of the placement seat 5 , and a sleeve rod 602 is sleeved on the outer peripheral wall of the sliding rod 603 .

[0034] The sleeve rod 602 is connected to the sliding rod 603 by a bolt, and the sleeve rod 602 is fixedly connected to the extrusion seat 6. When the cylinder 501 drives the placement seat 5 to move upward, the placement seat 5 drives the extrusion seat 6 to move. When the extrusion seat 6 moves, the inclined surface of the extrusion seat 6 contacts and squeezes the positioning frame 302.

[0035] At this time, the extrusion seat 6 pushes the sliding rod 603 to slide along the placement seat 5, driving the positioning seat 601 to move. The positioning seats 601 contact the four corners of the circuit board to position the circuit board, making it easier for the trepanning die 301 to trepan the circuit board, avoiding inaccurate positioning that leads to an increase in the processing defect rate.

[0036] By removing the sleeve rod 602, different extrusion seats 6 and positioning seats 601 can be replaced, which facilitates positioning of circuit boards of different sizes.

[0037] One end of the sliding rod 603 inside the placement seat 5 is fixedly connected to the sliding seat 604 , and the sliding seat 604 is slidably connected to the inner wall of the placement seat 5 .

[0038] The end of the sliding seat 604 is fixedly connected to a spring 605, which is fixedly connected to the placement seat 5. When the extrusion seat 6 moves, it pushes the sliding seat 604 to move and compress the spring 605. When the placement seat 5 moves downward and separates from the positioning frame 302, the spring 605 rebounds, pushing the extrusion seat 6 and the positioning seat 601 to move in the opposite direction and separate from the circuit board.

[0039] When the circuit board falls onto the conveying mechanism 4, the conveying mechanism 4 drives the processed circuit board to move, and at the same time conveys the new circuit board to between the placement seat 5 and the trepanning die 301 for trepanning.
