Description

A chip mounter feeder calibration device Technical Field

[0001] This utility model relates to the field of chip mounter feeder calibration technology, specifically a chip mounter feeder calibration device. Background Technology

[0002] A pick-and-place machine is a device that uses a placement head to pick up materials from the feeder and automatically place them onto the circuit board. Due to the influence of the feeder's feeding stability, the relative position of the material and the placement head after the placement head picks up the material is uncertain, i.e., there is a picking error. If the material is placed directly without correction, the picking error will inevitably be carried into the placement position, affecting the placement accuracy. Therefore, it is necessary to move the placement head to a visual correction position before placement, take a picture of the material with a camera, calculate the picking error, and then compensate for the picking error at the placement position to improve the placement accuracy.

[0003] An existing patent (publication number: CN220092203U) discloses a visual correction position compensation device for a chip mounter, including a mounting box. A chassis is fixedly connected to the left side of the front of the mounting box. A servo motor is housed within the chassis, and a cam is fixedly connected to the output shaft of the servo motor. A telescopic rod is fixedly connected to the inner cavity of the chassis, and a baffle is fixedly connected to the output end of the telescopic rod. A micro motor is fixedly connected to the inner side of the baffle. This invention utilizes the cooperation of a servo motor, a cam, a telescopic rod, a baffle, a micro motor, a brush, a drive motor, a transmission mechanism, a rotating shaft, a mounting plate, and a limiting mechanism. The limiting mechanism fixes the CCD camera, the output shaft of the drive motor drives the mounting plate to rotate through the transmission mechanism and the rotating shaft, and then the output shaft of the servo motor drives the baffle to move through the cam, causing the brush to adhere tightly to the lens surface of the CCD camera. The output shaft of the micro motor drives the brush to rotate, cleaning the lens. This invention is highly practical.

[0004] The aforementioned patented technology cleans the lens by driving a brush to rotate using a micro motor. However, in actual use, dust can adhere to the brush, leaving dust and impurities on the lens. This prevents the dust and impurities from being completely removed and still affects the lens's performance. Therefore, a chip mounter feeder calibration device is proposed.

The CCD camera is fixedly installed on the bottom outer surface of the second threaded plate, and the side plate is fixedly connected to the side of the second threaded plate.

A mounting frame is fixedly connected to the bottom outer surface of the L-shaped plate 5. A second motor 9 is fixedly mounted on the outer surface of the mounting frame. The output end of motor 9 is fixedly connected to one of the rotating shafts 6. Specifically, when the CCD camera 2 needs to be cleaned, the first motor 3 works, driving the support shaft 4 to rotate, which in turn moves the L-shaped plate 5, causing the brush 7 to rotate to the bottom of the CCD camera 2. The second motor 9 works, driving the rotating shaft 6 connected to its output end to rotate. When the rotating shaft 6 rotates, it drives the brush 7 to rotate and clean the lens. The first motor 3 continues to work, rotating the cleaning cotton 10 to the position corresponding to the lens of the CCD camera 2, causing the cleaning cotton 10 to rotate and further clean the surface of the lens, thereby improving the cleaning effect on the lens of the CCD camera 2 and preventing it from affecting the use of the CCD camera 2.

[0023] In this embodiment, an L-shaped frame 13 is fixedly connected to the top outer surface of the mounting platform 1, and two support plates arranged symmetrically on the bottom outer surface of the L-shaped frame 13 are fixedly connected to the bottom outer surface. A first lead screw 14 is rotatably connected between the two support plates. A third motor 15 is fixedly installed on the outer surface of one of the support plates. The output end of the third motor 15 is fixedly connected to the first lead screw 14. A first threaded plate is threadedly connected to the outer surface of the first lead screw 14. Specifically, the first lead screw 14 is driven to rotate by the third motor 15, and the first lead screw 14 drives the first threaded plate to move, thereby adjusting the position of the CCD camera 2.

[0024] In this embodiment, an inverted U-shaped frame 16 is fixedly connected to the bottom outer surface of the first threaded plate. A second lead screw 17 is rotatably connected between the opposite outer surfaces of the front and rear sides of the inverted U-shaped frame 16. A fourth motor is fixedly installed on the outer surface of the inverted U-shaped frame 16. The output end of the fourth motor is fixedly connected to the second lead screw 17.

[0025] In this embodiment, a support frame is fixedly connected to the outer surface of the connecting plate on which the brush 7 is installed. A nozzle 8 is installed on the outer surface of the support frame. The nozzle 8 is connected to the output end of an external liquid pump through a telescopic hose. Specifically, the external liquid pump draws the cleaning liquid to the nozzle 8, and the nozzle 8 sprays the cleaning liquid onto the brush 7 to increase the cleaning effect of the brush 7.

[0026] In this embodiment, synchronous pulleys 11 are fixedly sleeved on the outer surfaces of both rotating shafts 6, and a synchronous toothed belt 12 is meshed between the two synchronous pulleys 11.

[0027] In this embodiment, sliding rods are fixedly connected between the two support plates and between the opposite outer surfaces of the front and rear sides of the inverted U-shaped frame 16. The first threaded plate and the second threaded plate 18 are respectively movably sleeved on the outer surfaces of the two sliding rods. Specifically, the sliding rods guide and limit the first threaded plate and the second threaded plate 18, so that the first threaded plate and the second threaded plate 18 can move in a stable linear motion.

[0028] Working Principle: In use, this invention uses a CCD camera 2 to capture images of the feeder and the material to be mounted, and adjusts and calculates the feeder's CPK value accordingly, achieving fully automatic feeder calibration. When the CCD camera 2 needs cleaning, the first motor 3 operates, driving the support shaft 4 to rotate, which in turn moves the L-shaped plate 5, causing the brush 7 to rotate below the CCD camera 2. Then, the second motor 9 operates, driving the rotating shaft 6 connected to its output end to rotate. As the rotating shaft 6 rotates, it causes the brush 7 to rotate, cleaning the lens and allowing the cleaning fluid to be transferred. The cleaning fluid is delivered to the nozzle 8 and sprayed onto the brush 7 to improve the cleaning effect of the brush 7. Then, the first motor 3 continues to work, rotating the cleaning cotton 10 to the position corresponding to the lens of the CCD camera 2. When the second motor 9 drives the rotating shaft 6 connected to its output end to rotate, it drives the synchronous pulley 11 on it to rotate. Under the action of the synchronous toothed belt 12, another rotating shaft 6 is rotated, thereby causing the cleaning cotton 10 to rotate and further clean the surface of the lens, thus improving the cleaning effect on the lens of the CCD camera 2 and avoiding affecting the use of the CCD camera 2.

[0029] In use, the first lead screw 14 can be driven to rotate by the third motor 15, and the first lead screw 14 can drive the first threaded plate to move. The second lead screw 17 can be driven to rotate by the fourth motor, and the second lead screw 17 can drive the second threaded plate 18 to move, thereby moving the inverted U-shaped frame 16, thereby adjusting the position of the X and Y axes of the CCD camera 2, so that the CCD camera 2 can accurately photograph the feeder and the material.

[0030] It is worth noting that the CCD camera 2's image capture and correction is existing technology and common knowledge in the field. We are only using it and not modifying it, so the control method, circuit connection and specific working method will not be described in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
