Description

Technical Field

[0001] This utility model relates to the field of pick and place machines, and specifically to an anti-displacement pick and place device for SMT pick and place machines. Background Technology

[0002] SMT (Surface Mount Technology) placement machines are machines that accurately place SMD (Surface Mount Device) components onto corresponding pads on PCB circuit boards using a pick-and-place process. Surface mount components include capacitors, resistors, ICs, and other devices. These components can be placed quickly and accurately onto the circuit board using an SMT placement machine. However, as the placement board moves on the conveyor belt, it may shift due to inertia and other issues, resulting in deviations in the placement effect. Therefore, anti-displacement settings are required.

[0003] Among them, publication number CN221264116U discloses an anti-displacement placement device for an SMT pick-and-place machine. In this solution, the circuit board is limited during the transport process by limiting plates on both sides. Although this can move the circuit board to below the placement assembly, the gap between the circuit board and the limiting plates causes the circuit board to not be accurately positioned, thus reducing the accuracy of the circuit board placement. To address this, an anti-displacement placement device for an SMT pick-and-place machine is proposed. Utility Model Content

[0004] In view of the problems existing in the current SMT placement machine, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an anti-displacement placement device for SMT pick and place machines, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-displacement placement device for an SMT pick-and-place machine includes a conveyor frame, a conveyor belt, and a placement assembly. The conveyor belt is disposed inside the conveyor frame, and support seats are fixedly provided on both sides of the conveyor frame. The placement assembly is fixedly installed inside the support seats on both sides and is positioned across the top of the conveyor frame. A first limiting plate and a second limiting plate are fixedly provided on the inner walls of both sides of the conveyor frame above the conveyor belt, respectively. A cylinder is fixedly provided inside the first limiting plate, and a positioning plate is fixedly provided at the end of the piston rod of the cylinder. A positioning groove is provided on the side wall of the second limiting plate, and a pop-out plate is provided inside the positioning groove. An elastic telescopic rod is fixedly provided inside the second limiting plate, and one end of the elastic telescopic rod is fixedly connected to the side wall of the pop-out plate.

[0008] Preferably, the two sides of the positioning groove are arranged to expand to both sides, and the two ends of the positioning groove are V-shaped structures.

[0009] Preferably, both the interior of the first limiting plate and the interior of the second limiting plate are provided with recesses for placing the positioning plate and the ejector plate.

[0010] Preferably, the elastic telescopic rod includes a sleeve, a movable rod, and a spring. The movable rod is inserted into the inside of the sleeve and connected to the inner wall of the sleeve through the spring. The sleeve is fixedly connected to the second limiting plate, and the movable rod is fixedly connected to the ejector plate.

[0011] Furthermore, both the sidewalls of the first limiting plate and the sidewalls of the second limiting plate are provided with inclined guide surfaces.

[0012] Preferably, both the positioning plate and the ejector plate are located below the patch assembly.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model, through the provided cylinder, positioning plate and positioning groove, guides and limits the circuit board during the transportation process through the first limiting plate and the second limiting plate. When the circuit board moves to the position of the positioning plate, the cylinder is controlled to extend. The cylinder can drive the positioning plate to move and push the circuit board into the interior of the positioning groove, thereby fixing and clamping the circuit board, so that the surface mount assembly can accurately complete the surface mount operation and improve the quality of circuit board surface mount.

[0015] 2. In this utility model, by means of a pop-out plate and an elastic telescopic rod, when the circuit board is pushed and moved into the interior of the positioning groove, both the pop-out plate and the elastic telescopic rod are squeezed. After the circuit board is mounted, when the cylinder retracts, the elastic force of the elastic telescopic rod will pop out the pop-out plate and eject the circuit board from the interior of the positioning groove, so that the mounted circuit board can continue to be transported to the next process.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] The utility model provides Figure 1-3The illustrated anti-displacement placement device for an SMT pick-and-place machine includes a conveyor frame 1, a conveyor belt 2, and a placement assembly 3. The conveyor belt 2 is disposed inside the conveyor frame 1. Support seats 4 are fixedly provided on both sides of the conveyor frame 1. The placement assembly 3 is fixedly installed inside the support seats 4 on both sides and is positioned across the top of the conveyor frame 1. A first limiting plate 5 and a second limiting plate 6 are fixedly provided on the inner walls of both sides of the conveyor frame 1 above the conveyor belt 2, respectively. The side walls of the first limiting plate 5 and the second limiting plate 6 are provided with inclined guide surfaces 16. The circuit board is placed on the surface of the conveyor belt 2 and conveyed, so that the circuit board passes through the first limiting plate 5 and the second limiting plate 6 on both sides. Since the first limiting plate 5 and the second limiting plate 6 are provided with guide surfaces 16, the circuit board can be guided to move to the bottom of the patch assembly 3. A cylinder 7 is fixedly installed inside the first limiting plate 5, and a positioning plate 8 is fixedly installed at the end of the piston rod of the cylinder 7. A positioning groove 9 is opened on the side wall of the second limiting plate 6, and a pop-out plate 10 is provided inside the positioning groove 9. An elastic telescopic rod 11 is fixedly installed inside the second limiting plate 6. Furthermore, one end of the elastic telescopic rod 11 is fixedly connected to the side wall of the pop-out plate 10. Both the positioning plate 8 and the pop-out plate 10 are located below the patch assembly 3. When the circuit board moves to the position of the positioning plate 8, the control cylinder 7 extends. The cylinder 7 can drive the positioning plate 8 to move and push the circuit board into the positioning groove 9. The two sides of the positioning groove 9 are set to expand to both sides, and the two ends of the positioning groove 9 are V-shaped structures. During the process of the circuit board being pushed into the positioning groove 9 by the positioning plate 8, even if the circuit board cannot move precisely into the positioning groove 9, the positioning cylinder 7 can still move the circuit board into the positioning groove 9. The inclined surfaces on both sides of the positioning slot 9 can accurately push and position the circuit board, thereby firmly positioning and clamping the circuit board, enabling the surface mount assembly 3 to accurately mount the board, improving the quality of the board mounting. When the circuit board is pushed and moved into the positioning slot 9, the ejector plate 10 and the elastic telescopic rod 11 are both squeezed. After the board mounting is completed and the cylinder 7 retracts, the elastic force of the elastic telescopic rod 11 will eject the ejector plate 10 and eject the circuit board from the positioning slot 9, so that the mounted circuit board can continue to be transported to the next process.

[0025] like Figure 2-3 As shown, both the interior of the first limiting plate 5 and the interior of the second limiting plate 6 are provided with relief grooves 12 for placing the positioning plate 8 and the ejector plate 10. The relief grooves 12 can provide placement space for the positioning plate 8 and the ejector plate 10, so as to avoid affecting the conveying effect of the circuit board on the surface of the conveyor belt 2.

[0026] like Figure 2-4As shown, the elastic telescopic rod 11 includes a sleeve 13, a movable rod 14, and a spring 15. The movable rod 14 is inserted into the inside of the sleeve 13 and connected to the inner wall of the sleeve 13 through the spring 15. The sleeve 13 is fixedly connected to the second limiting plate 6. The movable rod 14 is fixedly connected to the pop-out plate 10. When the pop-out plate 10 is squeezed, the movable rod 14 retracts into the inside of the sleeve 13 and compresses the spring 15, so that the pop-out plate 10 has a tendency to extend elastically.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
