Description

Technical Field

[0001] The utility model relates to the technical field of optical detectors, in particular to a transport mechanism of an automatic optical detector. Background Art

[0002] Optical inspection instrument, referred to as AOI, is a device that detects common defects encountered in welding production based on optical principles. The AOI software has a comprehensive verification function that can reduce false positives during inspections and ensure that the inspection process is defect-free.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0036] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] When using the automatic optical inspection instrument, the user can take the test sample to the optical inspection instrument, and by controlling the switch of the inspection instrument, the inspection instrument automatically scans the PCBA product through the high-definition CCD camera, collects images, and compares the test points with the qualified parameters in the database. After image processing, the defects on the target product are checked and displayed / marked through the display or automatic marking for maintenance personnel to repair and SMT engineering personnel to improve the process.

[0038] In the related art, the existing optical detectors require the user to manually carry the detector to the place of use, or to push the detector on flat ground by installing moving wheels at the bottom of the detector. However, during the transportation process, the detector is easily tipped over due to the high center of gravity, and after reaching the location, the detector is difficult to fix under the movement of the moving wheels.

[0039] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a transport mechanism of an automatic optical detector. When the optical detector body 12 needs to be moved, it is only necessary to turn on the motor 21. The output end of the motor 21 drives the screw 22 to rotate. The screw 22 causes the slider 221 to move through a threaded connection. At the same time, the slider 221 drives another slider 221 sliding on the slide bar 223 to move synchronously through the connecting rod 224. By setting two sliders 221, the connecting rod 224 is subjected to balanced force at both ends when pressing the push rod 222, thereby improving the working stability of the component. The connecting rod 224 presses the push rod 222 to rotate and tilt downward, and the lifting plate 23 connected to the other end of the push rod 222 is pressed and rotated to slide downward inside the base 11, so that the four bottom ends of the lifting plate 23 are The universal wheel assembly 25 is exposed from the through slot 26, and the base 11 and the optical detector body 12 are lifted up. At this time, the user can push the entire detector assembly 1 to move. After moving to the specified position, the motor 21 is controlled to rotate in the opposite direction to retract the universal wheel assembly 25 to make the base 11 contact the ground to increase the friction and prevent the base 11 from shifting. After placement, the user can take the test sample to the optical detector body 12, and by controlling the detector switch, the detector automatically scans the PCBA product through the high-definition CCD camera, collects images, and compares the test points with the qualified parameters in the database. After image processing, the defects on the target product are checked, and the defects are displayed / marked through a display or automatic marking for maintenance personnel to repair and SMT engineering personnel to improve the process.

[0040] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0041] Combination Figure 1-Figure 4The embodiment of the present application provides a transport mechanism of an automatic optical detector, including a detector assembly 1; the detector assembly 1 includes: an optical detector body 12 is arranged on the top of a base 11; a transport assembly 2 is arranged on the detector assembly 1, and the transport assembly 2 includes: a motor 21 is arranged on the outer wall of the base 11, and the output end of the motor 21 passes through the base 11 and is fixedly connected with a screw 22, a slider 221 is threadedly arranged on the screw 22, and the slider 221 is slidably connected to the base 11; a slide bar 223 is arranged inside the base 11, a slide bar 221 is slidably arranged on the slide bar 223, a connecting rod 224 is arranged between the slide bars 221, and a top rod 222 is rotatably arranged on the connecting rod 224; a lifting plate 23 is slidably arranged on the inner wall of the base 11, and the lifting plate 23 and the other end of the top rod 222 are rotatably connected; a universal wheel assembly 25 is symmetrically arranged at the bottom of the lifting plate 23; a through groove 26 is arranged at the bottom of the base 11.

[0042] When the optical detector body 12 needs to be moved, it is only necessary to turn on the motor 21. The output end of the motor 21 drives the screw rod 22 to rotate. The screw rod 22 makes the slider 221 move through the threaded connection. At the same time, the slider 221 drives another slider 221 sliding on the slide rod 223 to move synchronously through the connecting rod 224. By setting two sliders 221, the connecting rod 224 is subjected to balanced force at both ends when pressing the push rod 222, thereby improving the working stability of the component. The connecting rod 224 presses the push rod 222 to rotate and tilt downward, and the lifting plate 23 connected to the other end of the push rod 222 is pressed and rotated to slide downward inside the base 11, so that the four universal wheel assemblies 25 at the bottom of the lifting plate 23 are exposed from the through groove 26, and the base 1 1 and the optical detector body 12 are lifted up. At this time, the user can push the entire detector assembly 1 to move. After moving to the specified position, the motor 21 is controlled to rotate in the opposite direction to retract the universal wheel assembly 25 to make the base 11 contact with the ground to increase the friction and prevent the base 11 from shifting. After placement, the user can take the test sample to the optical detector body 12, and by controlling the detector switch, the detector automatically scans the PCBA product through the high-definition CCD camera, collects images, and compares the test points with the qualified parameters in the database. After image processing, the defects on the target product are checked, and the defects are displayed / marked through a display or automatic marking for maintenance personnel to repair and SMT engineering personnel to improve the process.

[0043] In some embodiments, a protective cover 211 is disposed outside the motor 21. The protective cover 211 can protect the motor 21 to prevent water from entering the motor 21 or dust from covering the motor 21.

[0044] In some embodiments, a limit block 232 is disposed on the inner side wall of the base 11, and the limit block 232 is disposed above the lifting plate 23. The limit block 232 is helpful to prevent the lifting plate 23 from over-rising and colliding with the slider 221, causing damage to the components.

[0045] In some embodiments, an anti-skid pad is provided at the bottom of the base 11. The anti-skid pad is made of rubber material and has a large friction force, which is beneficial to improving the stability of the entire device when it is stationary.

[0046] In some embodiments, a spring hydraulic rod 24 is disposed inside the base 11. The spring hydraulic rod 24 includes a damping spring and a hydraulic rod, and can reduce the force through the deformation characteristics of the hydraulic rod and the damping spring, thereby improving the stability of the lifting plate 23 during movement.

[0047] In some embodiments, the universal wheel assembly 25 includes: a connecting plate 251 disposed at the bottom of the lifting plate 23, a connecting shaft 252 rotatably disposed on the connecting plate 251, a mounting plate 253 disposed on the connecting shaft 252, a damping spring rod 254 disposed on the mounting plate 253, a fixing member 256 disposed at the other end of the damping spring rod 254, and the fixing member 256 disposed on the tire 255. During the movement, the entire universal wheel assembly 25 is subjected to the pressure of the top base 11 and the friction during the movement, which will produce a large vibration, affecting the stability of the optical detector body 12 during the movement. By arranging a plurality of damping spring rods 254 on the mounting plate 253, the vibration can be reduced through the deformation principle of the damper and the spring, thereby improving the stability of the entire device during the movement.

[0048] In some embodiments, the mounting plate 253 is polygonal in shape. The polygonal design is conducive to adding more damping spring rods 254 to improve the shock absorption effect.

[0049] In some embodiments, the tire 255 is provided with a tread groove 257. The irregular design of the tread groove 257 is conducive to increasing the friction between the tire 255 and the ground, and improving the stability of the entire device during movement.
