Description

An automated dispensing device with rapid positioning Technical Field

[0001] This utility model relates to the field of hot melt machines, and in particular to an automatic dispensing device that can be quickly positioned. Background Technology

[0002] SMT (Surface Mount Technology) production lines, also known as surface mount technology, are a new generation of electronic assembly technology developed from hybrid integrated circuit board technology. Characterized by surface mounting of components and reflow soldering, it has become a next-generation assembly technology in electronic product manufacturing. The main equipment in an SMT production line includes: printers, pick-and-place machines, reflow soldering machines, through-hole soldering machines, wave ovens, and testing and packaging equipment. The widespread application of SMT has promoted the miniaturization and multi-functionality of electronic products, providing conditions for mass production and low-defect production. The most common piece of equipment in an SMT production line is the dispensing machine, which applies adhesive to the circuit board.

[0003] However, traditional dispensing machines, such as the one protected by the patent application number CN202121588803.5, entitled "Positioning Device for Quickly Dispensing Wire Harness Tape," require manual feeding and unloading. The dispensing machine is slow in locking the integrated circuit board to be dispensed, which seriously affects the production efficiency of the dispensing machine. Summary of the Invention

[0004] Therefore, it is necessary to provide an automatic dispensing device that can quickly position itself, addressing the technical problems of traditional dispensing machines requiring manual loading and unloading and slow speed in locking the integrated circuit board to be dispensed.

[0005] An automatic dispensing device capable of rapid positioning includes: a dispensing mechanism, a dispensing mechanism, a belt conveyor, two positioning mechanisms, and a control mechanism.

[0006] The dispensing mechanism includes an XYZ moving platform, a drive board, an industrial camera, a connecting column, and a dispensing nozzle; the XYZ moving platform is connected to an external connecting frame, and the drive end of the XYZ moving platform is connected to the drive board; the industrial camera is mounted on the drive board, and the dispensing nozzle is connected to the drive board through the connecting column;

[0007] The glue delivery mechanism includes a glue tank, a glue pump, and a glue delivery hose; the glue pump is located inside the glue tank and is connected to the glue nozzle through the glue delivery hose.

[0008] The belt conveyor is located below the drive plate, and limit plates are provided on both sides of the belt conveyor; a compression notch is provided in the middle area of ​​the two limit plates; a support plate is provided on the bracket of the belt conveyor.

[0009] Two positioning mechanisms are symmetrically arranged on both sides of the belt conveyor and are both connected to the support plate. Each positioning mechanism includes a drive cylinder, a drive plate, a push cylinder, and an L-shaped extrusion plate. The drive cylinder is connected to the support plate. The drive cylinder is driven by the push cylinder through the drive plate. The drive cylinder drives the push cylinder to move up and down through the drive plate. The push cylinder is driven by the L-shaped extrusion plate. The push cylinder drives the L-shaped extrusion plate to insert into or withdraw from one of the extrusion notches.

[0010] The XYZ mobile platform, the industrial camera, the glue extraction pump, the belt conveyor, the two drive cylinders, and the two push cylinders are all electrically connected to the control mechanism.

[0011] In one embodiment, anti-slip pads are provided on both inner walls of the L-shaped extrusion plate.

[0012] In one embodiment, the anti-slip pad is a soft silicone pad.

[0013] In one embodiment, the anti-slip pad is a soft rubber pad.

[0014] In one embodiment, the anti-slip mat is a soft plastic mat.

[0015] In one embodiment, the drive plate is a circular plate structure.

[0016] In one embodiment, the drive board is a rectangular plate structure.

[0017] In one embodiment, the connecting column is a cylindrical structure.

[0018] In one embodiment, the connecting post is a quadrangular prism structure.

[0019] In one embodiment, the drive carrier plate is a rectangular plate structure.

[0020] During the operation of the aforementioned rapid-positioning automatic dispensing device, it should be noted that the integrated circuit board to be dispensed needs to be placed in the carrier tray before dispensing. A belt conveyor transports the carrier tray carrying the integrated circuit board to be dispensed. The carrier tray moves to two L-shaped extrusion plates in the two positioning mechanisms. An industrial camera captures images of the integrated circuit board to be dispensed and transmits the captured images to the control mechanism. The control mechanism compares the images with images in the image library to determine the position and orientation of the integrated circuit board to be dispensed. After the orientation of the integrated circuit board to be dispensed is correct, a push cylinder drives the L-shaped extrusion plate to insert into the extrusion notch, coordinating with another L-shaped extrusion plate to extrude and fix the carrier tray. The drive cylinder, through the drive plate, drives the push cylinder to move upward, thereby driving the carrier tray upward through the L-shaped extrusion plates, disengaging it from the belt conveyor. The XYZ moving platform, through the drive plate and connecting column, drives the dispensing nozzle to move above the integrated circuit board to be dispensed. During this process, the glue pump delivers the adhesive from the glue bucket to the dispensing nozzle through the glue delivery hose, thus performing the dispensing operation on the integrated circuit board to be dispensed. After dispensing is complete, the drive cylinder, via the drive plate and push cylinder, drives the L-shaped extrusion plate downwards, thereby causing the carrier plate to move downwards. Ultimately, the carrier plate abuts against the belt conveyor, and the push cylinder drives the L-shaped extrusion plate away from another L-shaped extrusion plate. This allows the belt conveyor to transport the carrier plate containing the dispensed integrated circuit board to other workstations. This rapidly positioning automatic dispensing device can perform loading and unloading operations, quickly fix the integrated circuit board, and achieve automatic dispensing with high efficiency and stability.

[0029] Please refer to Figures 1 to 3. This utility model provides an automatic dispensing device 10 with rapid positioning. The automatic dispensing device 10 with rapid positioning includes: a dispensing mechanism 100, a dispensing mechanism 200, a belt conveyor 300, two positioning mechanisms 400 and a control mechanism 500.

[0030] The dispensing mechanism 100 includes an XYZ moving platform 110, a drive board 120, an industrial camera 130, a connecting post 140, and a dispensing nozzle 150. The XYZ moving platform 110 is connected to an external connecting frame, and the drive end of the XYZ moving platform 110 is connected to the drive board 120. In this embodiment, the drive board 120 is a circular plate structure. In another embodiment, the drive board 120 is a rectangular plate structure. The industrial camera 130 is mounted on the drive board 120, and the dispensing nozzle 150 is connected to the drive board 120 via the connecting post 140. In this embodiment, the connecting post 140 is a cylindrical structure. In another embodiment, the connecting post 140 is a quadrangular prism structure.

[0031] The glue dispensing mechanism 200 includes a glue tank 210, a glue pump 220, and a glue dispensing hose 230. The glue pump 220 is installed inside the glue tank 210 and is connected to the dispensing nozzle 150 through the glue dispensing hose 230.

[0032] The belt conveyor 300 is positioned below the drive plate 120, and limit plates 310 are provided on both sides of the belt conveyor 300. A compression notch 301 is provided in the middle area of ​​the two limit plates 310. A support plate 320 is provided on the bracket of the belt conveyor 300.

[0033] Two positioning mechanisms 400 are symmetrically arranged on both sides of the belt conveyor 300 and are both connected to the support plate 320. Each positioning mechanism 400 includes a drive cylinder 410, a drive carrier plate 420, a push cylinder 430, and an L-shaped extrusion plate 440. The drive cylinder 410 is connected to the support plate 320. The drive cylinder 410 is driven by the push cylinder 430 via the drive carrier plate 420. The drive cylinder 410 drives the push cylinder 430 to move up and down via the drive carrier plate 420. In this embodiment, the drive carrier plate 420 is a rectangular plate structure. The push cylinder 430 is driven by the L-shaped extrusion plate 440. The push cylinder 430 drives the L-shaped extrusion plate 440 to insert into or withdraw from an extrusion notch 301.

[0034] The XYZ mobile platform 110, industrial camera 130, glue pump 220, belt conveyor 300, two drive cylinders 410, and two push cylinders 430 are all electrically connected to the control mechanism 500. It should be noted that in this embodiment, the control mechanism 500 is a lower-level machine, specifically a PLC. In another embodiment, the control mechanism 500 is a microcontroller. In other embodiments, the control mechanism 500 includes a higher-level machine and a lower-level machine, which are electrically connected. The control mechanism 500 can coordinate the operation of the XYZ mobile platform 110, industrial camera 130, glue pump 220, belt conveyor 300, two drive cylinders 410, and two push cylinders 430 to ensure the stable operation of the automatically dispensing device 10, which can be quickly positioned.

[0035] To increase the operational stability of the positioning mechanism 400, in one embodiment, anti-slip pads are provided on both inner walls of the L-shaped extrusion plate 440. The anti-slip pads increase the friction between the L-shaped extrusion plate 440 and the support plate 600 carrying the integrated circuit board 700 to be dispensed. This prevents direct, rigid contact between the L-shaped extrusion plate 440 and the support plate 600, thus avoiding mutual wear. In this embodiment, the anti-slip pad is a soft silicone pad. In another embodiment, the anti-slip pad is a soft rubber pad. In yet another embodiment, the anti-slip pad is a soft plastic pad. Thus, the anti-slip pads provided on both inner walls of the L-shaped extrusion plate 440 increase the operational stability of the positioning mechanism 400.

[0036] During operation of the aforementioned rapid-positioning automatic dispensing device 10, it should be noted that the integrated circuit board 700 to be dispensed needs to be placed in the carrier tray 600 before dispensing. The belt conveyor 300 transports the carrier tray 600 carrying the integrated circuit board 700. The carrier tray 600 moves onto the two L-shaped extrusion plates 440 of the two positioning mechanisms 400. The industrial camera 130 captures an image of the integrated circuit board 700 and transmits the captured image to the control mechanism 500. The control mechanism 500 compares the image with images in the image library to determine the position and orientation of the integrated circuit board 700. Once the orientation of the integrated circuit board 700 is correct... The push cylinder 430 drives the L-shaped extrusion plate 440 to insert into the extrusion notch 301, and in conjunction with another L-shaped extrusion plate 440, extrudes and fixes the carrier plate 600. The drive cylinder 410 drives the push cylinder 430 to move upward through the drive plate 420, thereby driving the carrier plate 600 to move upward through the L-shaped extrusion plate 440, disengaging it from the belt conveyor 300. The XYZ mobile platform 110 drives the dispensing nozzle 150 to move above the integrated circuit board 700 to be dispensed through the drive plate 120 and the connecting column 140. During this process, the glue pump 220 transfers the adhesive in the glue tank 210 to the dispensing nozzle 150 through the glue delivery hose 230, thereby performing the dispensing operation on the integrated circuit board 700 to be dispensed. After dispensing is complete, the drive cylinder 410 drives the L-shaped extrusion plate 440 downward via the drive carrier plate 420 and the push cylinder 430, thereby causing the carrier plate 600 to move downward. Finally, the carrier plate 600 abuts against the belt conveyor 300, and the push cylinder 430 drives the L-shaped extrusion plate 440 away from the other L-shaped extrusion plate 440. This allows the belt conveyor 300 to transport the carrier plate 600, which holds the dispensed integrated circuit board 700, to other workstations. The aforementioned automatic dispensing device 10, capable of rapid positioning, can perform loading and unloading operations, quickly fix the integrated circuit board 700, and achieve automatic dispensing with high efficiency and stability.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
