Description

Technical Field

[0001] This utility model relates to the field of pick and place machine technology, specifically to a multi-head high-speed scanning mirror for pick and place machines. Background Technology

[0002] As electronic products become increasingly miniaturized and high-density, the requirements for the precision and speed of pick-and-place machines are becoming increasingly stringent. Traditional pick-and-place machines, using single-head or dual-head placement, are inefficient and cannot meet the demands of modern production. Our existing multi-head flying alignment technology for pick-and-place machines is no longer sufficient to meet the current high-end market demands, necessitating the rapid development of a high-efficiency, relatively low-cost flying alignment technology.

[0003] However, in actual use, existing equipment requires each head to be equipped with a camera and lens alignment module for single-head flight alignment, which is relatively expensive and difficult to improve efficiency; in view of this, we propose a multi-head high-speed scanning lens for chip mounters. Utility Model Content

[0004] The purpose of this invention is to provide a multi-head high-speed scanning mirror for a chip mounter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-head high-speed scanning mirror for a chip mounter, comprising a vertical plate of the machine head, a scanning mirror assembly provided on the outer wall of the vertical plate of the machine head, the scanning mirror assembly including a motor, the motor being fixedly connected to the outer wall of the vertical plate of the machine head, the output end of the motor being fixedly connected to a drive pulley through the vertical plate of the machine head, a synchronous belt being drivenly connected to the outer wall of the drive pulley, a driven pulley being rotatably mounted on the outer wall of the vertical plate of the machine head, a lifting plate being fixedly connected to the outer wall of the synchronous belt, a vacuum pump assembly being fixedly connected to the outer wall of the lifting plate, and a lifting tube being rotatably mounted on the lower end of the lifting plate;

[0006] The suction nozzle is fixedly connected to the end of the lifting tube. A high-precision linear slide rail is fixedly connected to the inner wall of the vertical plate of the machine head. A rotating pulley is rotatably installed on the inner wall of the vertical plate of the machine head. A second synchronous belt is drivenly connected to the outer wall of the rotating pulley. A movable frame is fixedly connected to the outer wall of the second synchronous belt. A scanning mirror module is provided on the outer wall of the movable frame. A motor mounting port is provided on the outer wall of the vertical plate of the machine head.

[0007] Preferably, the outer wall of the movable frame is slidably connected to the inner wall of the vertical plate of the machine head, so that the movable frame can move smoothly.

[0008] Preferably, the number of motors is several, and the several motors are arranged in a linear array on the outer wall of the vertical plate of the machine head.

[0009] Preferably, the centerline of the driving pulley and the centerline of the driven pulley are both on the same plane.

[0010] Preferably, the outer wall of the vertical plate of the machine head is provided with a rotating adsorption assembly, the rotating adsorption assembly includes a second motor, the second motor is fixedly connected to the outer wall of the vertical plate of the machine head, the output end of the second motor passes through the vertical plate of the machine head and is fixedly connected to a second drive pulley, the outer wall of the second drive pulley is driven by a third synchronous belt, the outer wall of the vertical plate of the machine head is rotatably mounted with a second driven pulley, and the inner wall of the second driven pulley is fixedly connected to a transmission sleeve.

[0011] Preferably, the inner wall of the transmission sleeve is fitted onto the outer wall of the lifting tube, so that the transmission sleeve can drive the lifting tube to rotate and move when it rotates.

[0012] Preferably, the outer wall of the lifting tube is slidably connected to the inner wall of the transmission sleeve, so that the lifting tube can move smoothly when lifting.

[0013] Compared with the prior art, this utility model provides a multi-head high-speed scanning mirror for a pick-and-place machine, which has the following beneficial effects:

[0014] 1. This pick-and-place machine features a multi-head high-speed scanning lens. The starting motor drives the first drive pulley to rotate, which in turn displaces the first synchronous belt. This displacement of the first synchronous belt then moves the lifting plate, ultimately allowing the vacuum pump unit to move vertically up and down with the lifting plate. This ensures the nozzle can more accurately attach to the placed components. Meanwhile, the motor mounted at the motor mounting port drives the rotating pulley to rotate, which in turn moves the scanning lens module on the moving frame via the second synchronous belt. The machine then captures multiple Z-axis images of the components at high speed for software processing and analysis, achieving instantaneous imaging during flight.

[0015] 2. This pick-and-place machine features a multi-head high-speed scanning lens. When starting motor one and the motor mounted on the motor mounting port, motor two can be started, causing motor two to drive the active pulley two to rotate. This, in turn, forces the driven pulley two to rotate through the transmission of synchronous belt three. As the driven pulley two rotates, it drives the transmission sleeve to rotate. When the transmission sleeve rotates, the protrusions on the inner wall of the transmission sleeve and the grooves on the outer wall of the lifting tube transmit power. Ultimately, this allows the lifting tube to rotate smoothly with the transmission sleeve while moving up and down. This ensures that when the rotary nozzle is adsorbing objects, the suction force is evenly distributed across the entire contact surface through rotational motion. This helps to better adsorb irregularly shaped objects and avoids objects falling off due to insufficient local adsorption force, thus further improving the overall stability and practicality.

Detailed Implementation

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a multi-head high-speed scanning mirror for a chip mounter, including a vertical plate 1 for the machine head, a scanning mirror assembly 2 on the outer wall of the vertical plate 1, the scanning mirror assembly 2 including a motor 201, the motor 201 being fixedly connected to the outer wall of the vertical plate 1, the output end of the motor 201 being fixedly connected to a drive pulley 202 through the vertical plate 1, a synchronous belt 203 being drivenly connected to the outer wall of the drive pulley 202, a driven pulley 204 being rotatably mounted on the outer wall of the vertical plate 1, a lifting plate 205 being fixedly connected to the outer wall of the synchronous belt 203, a vacuum pump assembly 206 being fixedly connected to the outer wall of the lifting plate 205, and a lifting tube 207 being rotatably mounted on the lower end of the lifting plate 205.

[0024] Furthermore, the suction nozzle 208 is fixedly connected to the end of the lifting tube 207, a high-precision linear slide rail 209 is fixedly connected to the inner wall of the head vertical plate 1, a rotating pulley 210 is rotatably installed on the inner wall of the head vertical plate, a synchronous belt 211 is connected to the outer wall of the rotating pulley 210, a movable frame 212 is fixedly connected to the outer wall of the synchronous belt 211, a scanning mirror module 213 is provided on the outer wall of the movable frame 212, and a motor mounting port 214 is provided on the outer wall of the head vertical plate 1.

[0025] In an embodiment of this utility model, the outer wall of the movable frame 212 is slidably connected to the inner wall of the vertical plate 1 of the machine head, so that the movable frame 212 can move smoothly. The number of motors 201 is several, and the several motors 201 are arranged in a linear array on the outer wall of the vertical plate 1 of the machine head. The center line of the driving pulley 202 and the center line of the driven pulley 204 are both on the same plane.

[0026] Furthermore, a rotating adsorption assembly 3 is provided on the outer wall of the vertical plate 1 of the machine head. The rotating adsorption assembly 3 includes a second motor 301, which is fixedly connected to the outer wall of the vertical plate 1 of the machine head. The output end of the second motor 301 passes through the vertical plate 1 of the machine head and is fixedly connected to a second drive pulley 302. The outer wall of the second drive pulley 302 is driven by a third synchronous belt 303. A second driven pulley 304 is rotatably installed on the outer wall of the vertical plate 1 of the machine head. A transmission sleeve 305 is fixedly connected to the inner wall of the second driven pulley 304. The inner wall of the transmission sleeve 305 is sleeved on the outer wall of the lifting tube 207, so that the transmission sleeve 305 can drive the lifting tube 207 to rotate and move when rotating. The outer wall of the lifting tube 207 is slidably connected to the inner wall of the transmission sleeve 305, so that the lifting tube 207 can move smoothly when lifting.

[0027] In this invention, during daily use, the motor 201 and the motor mounted on the motor mounting port 214 are started, causing the motor 201 to drive the drive pulley 202 to rotate, which in turn causes the synchronous belt 203 to move. This movement of the synchronous belt 203 causes the lifting plate 205 to move as well, ultimately allowing the vacuum pump unit 206 to move vertically up and down with the lifting plate 205 during operation. This allows the nozzle 208 to be more accurately attached to the placed components. The motor mounted on the motor mounting port 214 drives the rotating pulley 210 to rotate, which in turn causes the synchronous belt 211 to move the scanning mirror module 213 on the moving frame 212. This module then captures multiple Z-axis images of the components at high speed for software processing and analysis, achieving instantaneous imaging during flight. Based on the MARK point position, high-resolution images of the components on the nozzle 208 are accurately captured. The precise placement position of each component is calculated by the software algorithm, thereby controlling the placement head to move at high speed to complete the component placement.

[0028] When starting motor 201 and the motor mounted on motor mounting port 214, motor 301 can be started, which drives the drive pulley 302 to rotate. This, in turn, forces the driven pulley 304 to rotate through the transmission of the synchronous belt 303. As the driven pulley 304 rotates, it drives the transmission sleeve 305 to rotate. When the transmission sleeve 305 rotates, it transmits power through the protrusions on the inner wall of the transmission sleeve 305 and the grooves on the outer wall of the lifting tube 207. This allows the lifting tube 207 to rotate smoothly with the transmission sleeve 305 while moving up and down. This ensures that when the rotating nozzle 208 is adsorbing objects, the suction force can be evenly distributed across the entire contact surface through rotational motion. This helps to better adsorb irregularly shaped objects and avoids objects falling off due to insufficient local adsorption force, thereby further improving the overall stability and practicality.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
