[0037] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0038] As described in the background art, brushing material to perform welding inspection on a circuit board can easily cause physical damage to the circuit board surface, solder joints, or components.

[0039] In order to solve this technical problem, the present invention provides an electronic component visual inspection mechanism, which is applied to circuit board inspection.

[0040] Specifically, please refer to Figure 1-Figure 7 The electronic component visual inspection mechanism specifically includes: a base 1, a conveying device 101 provided on the base 1, and a clamping device 102 provided on the conveying device 101, further comprising a vibration mechanism 2 provided on the base 1 and a blowing mechanism 3 provided on the base 1, the clamping device 102 is used to clamp and fix the circuit board, and the conveying device 101 is used to drive the clamping device 102 to move;

[0041] The vibration mechanism 2 includes a support frame 201 provided on the base 1, a mounting base 202 provided on the support frame 201, a receiving base 203 provided on the support frame 201, a thimble 204 slidably provided on the receiving base 203, and an isolation component 212 provided on the receiving base 203;

[0042] The blowing mechanism 3 includes a microscope 301 arranged on the mounting base 202, a U-shaped tube 302 arranged on the mounting base 202, and an expansion component 306 arranged on the base 1. The microscope 301 is an existing 3D microscope 301, and the circuit board is flat-scanned and inspected through the microscope 301.

[0043] The electronic component visual inspection mechanism provided by the present invention solves the problem in the prior art that brushing material is used to perform welding inspection on a circuit board, which easily causes physical damage to the circuit board surface, solder joints or components. The present application provides a vibration mechanism 2 and a blowing mechanism 3. The vibration plate 208 is driven to vibrate by the ejector pin 204. The vibration generated by the vibration plate 208 is transmitted to the circuit board, so that parts with loose soldering on the circuit board are detached, thereby realizing non-contact welding inspection and preventing physical damage to parts.

[0044] By providing the vibration mechanism 2 and the blowing mechanism 3, and by cooperating with the receiving seat 203 and the vibration plate 208, all the parts dropped from the circuit board are collected together and cushioned when the parts fall, thereby reducing the damage rate of the parts and realizing the recycling of the parts, thus solving the problem of damage to the circuit board parts caused by detection in the prior art;

[0045] By setting up the vibration mechanism 2 and the blowing mechanism 3, compressed air is used to blow away the parts on the circuit board that are not firmly welded, so as to prevent the situation where local parts are not completely fallen off due to vibration. At the same time, in conjunction with the microscope 301, the condition of the parts on the circuit board can be observed in real time, solving the problem of whether the parts on the circuit board are firmly welded in the prior art.

[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0049] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , a visual inspection mechanism for electronic components, whose vibration mechanism 2 also includes a slide 205 arranged on the receiving seat 203, a push plate 206 is slidably arranged on the slide 205, and an ejector 204 is arranged on the ejector plate 206, and a spring 207 is arranged on the corresponding surfaces of the slide 205 and the ejector plate 206, and a vibration plate 208 is provided on the clamping device 102, and a plurality of protrusions 209 are provided on the vibration plate 208, and the plurality of protrusions 209 cooperate with the ejector 204. When the conveying device 101 drives the clamping device 102 to move, the clamping device 102 moves synchronously with the circuit board and the vibration plate 208, and the protrusion 209 on the vibration plate 208 first contacts the ejector 204, wherein the protrusion 209 is composed of multiple trapezoids. When the ejector 204 continuously contacts the protrusion 209, the ejector 204 passes Due to the elasticity of spring 1 207, ejector pin 204 first descends and then continuously moves up and down. At this time, the up and down displacement of ejector pin 204 contacts protrusion 209, causing protrusion 209 to vibrate continuously, thereby causing vibration plate 208 to vibrate synchronously. The vibration of vibration plate 208 is transmitted to clamping device 102, causing the circuit board to vibrate synchronously. The vibration of vibration plate 208 is transmitted to the circuit board, and then the microscope 301 is used for flat scanning inspection. When the circuit board is inspected for loosely welded parts, no physical damage to the circuit board is caused. The purpose of providing spring 1 207 is to drive vibration plate 208 and ejector pin 204 to reset. Vibration plate 208 slides downward along chute 205 and can be used to compress the air in the chute, wherein vibration plate 208 acts as a piston.

[0050] Furthermore, storage boxes 210 are provided on both sides of the receiving seat 203. The ends of the receiving seat 203 are arranged in a trapezoidal shape. Due to the trapezoidal shape of the receiving seat 203, when parts fall off the surface of the circuit board on the clamping device 102, the parts on the circuit board fall on the surface of the receiving seat 203 and slide from the surface of the receiving seat 203 to the storage box 210 for collection. If the parts fall off only due to loose welding and are not damaged, they can usually be used again after cleaning and re-welding. Collecting the parts helps to quickly locate the root cause of the problem. The purpose of providing the storage box 210 is to collect the fallen circuit board parts. By setting the end of the receiving seat 203 in a trapezoidal shape, the fallen circuit board parts can slide along the inclined surface through the trapezoidal slope, so that the slid circuit board parts can be gathered in the storage box 210.

[0051] Furthermore, a wedge-shaped groove 211 is provided on the side of the vibration plate 208 away from the protrusion 209. When a component on the circuit board falls due to vibration, the component will first fall on the vibration plate 208 and then be buffered by the wedge-shaped groove 211 on the vibration plate 208. The component slides along the direction of the wedge-shaped groove 211 and falls to the surface of the receiving seat 203, thereby preventing the component from falling directly on the receiving seat 203 and being damaged. The wedge-shaped groove 211 is used to receive the fallen circuit board component, allowing the fallen circuit board component to slide along the wedge-shaped groove 211 and finally transfer the circuit board component to the receiving seat 203, thereby providing secondary buffering for the fallen circuit board component and reducing damage to the circuit board component.

[0052] Furthermore, the isolation component 212 includes a rotating shaft 2121 rotatably arranged in the storage box 210, an isolation plate 2122 is provided on the rotating shaft 2121, an adjustment block 2123 is slidably arranged on the outer side of the rotating shaft 2121, a guide column 2124 is provided on the storage box 210, the adjustment block 2123 is slidably arranged on the guide column 2124, a spiral groove 2125 is provided in the isolation plate 2122, and a push column 2126 is provided on the rotating shaft 2121. The push column 2126 and the spiral groove 2125 are adapted to each other. When the storage box 210 is matched with the isolation plate 2122, the parts in the storage box 210 can be isolated from the outside world, thereby reducing the situation where the fallen parts become wet or contaminated with dust. The guide column 2124 is used to adjust the adjustment block 2123. 123 is guided to prevent the adjustment block 2123 from rotating. When the vibration plate 208 contacts the adjustment block 2123 and pushes it, the adjustment block 2123 moves along the rotation axis 2121. The spiral groove 2125 on the adjustment block 2123 squeezes the push column 2126, causing the push column 2126 to rotate synchronously with the rotation axis 2121. The rotation of the rotation axis 2121 drives the isolation plate 2122 to rotate synchronously, causing the isolation plate 2122 to rotate and expand. At this time, all the parts that fall from the circuit board will fall into the storage box 210 for collection. If there are fallen parts in the storage box 210, it can be intuitively seen that the inspected circuit board has defects. On the contrary, if there are no fallen circuit board parts in the storage box 210, the circuit board can be processed for the next step.

[0053] The clamping device 102 is vibrated by the vibration mechanism 2, and the vibration of the clamping device 102 is transmitted to the circuit board, and then the microscope 301 is used for flat scanning inspection, so that when the circuit board is inspected for parts with loose soldering, no physical damage will occur to the circuit board. At the same time, the fallen parts are automatically collected and the damage rate of the fallen parts is reduced, which helps to quickly locate the root cause of the problem. At the same time, the undamaged parts can continue to be used.

[0054] Example 2 further optimizes the electronic component visual inspection mechanism provided in Example 1. Specifically, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the blowing mechanism 3 also includes a plurality of discharge holes 303 provided on the U-shaped tube 302, and a retaining ring 304 is rotatably provided on the mounting seat 202. The retaining ring 304 is provided on the outside of the U-shaped tube 302, and the U-shaped tube 302 is connected to the slide groove 205. The discharge holes 303 on the U-shaped tube 302 are arranged at an angle. Compared with the vertical design, the vertical air jet cannot effectively blow off the parts that are not firmly welded. The inclined air jet is conducive to blowing off the parts that are not firmly welded. The retaining ring 304 is used to block the discharge hole 303. When the vibration plate 208 moves and squeezes the ejector pin 204, the ejector pin 204 first moves downward and then moves up and down. Displacement, wherein the upward displacement of the ejector pin 204 does not return to the initial position, but only moves upward a short distance of the inclined surface of the protrusion 209. As a result, when the vibration plate 208 contacts the ejector pin 204, the ejector pin 204 and the ejector plate 206 move downward, so that the air in the multiple inclined grooves is compressed into the U-shaped tube 302, causing the pressure in the U-shaped tube 302 to gradually increase. When the retaining ring 304 rotates and releases the blockage of the discharge hole 303, the compressed air in the U-shaped tube 302 is ejected from the discharge hole 303, and the ejected air blows away the loosely soldered parts of the circuit board, causing the blown-off parts to fall onto the vibration plate 208;

[0055] Furthermore, an extension portion 305 is provided at the end of the retaining ring 304, and the extension portion 305 is adapted to the discharge hole 303. The extension portion 305 is tilted on the retaining ring 304, so that the discharge hole 303 is less blocked, thereby reducing the loss of the discharged air from the discharge hole 303. Figure 7 As shown, when the baffle ring 304 rotates and releases the blockage of the discharge hole 303, the extension portion 305 rotates synchronously, partially blocking the air discharged from the discharge hole 303 through the extension portion 305, so that the direction of the discharged air is constantly changing. The direction of air discharge is controlled by the rotation of the baffle ring 304 and the extension portion 305;

[0056] Furthermore, the unfolding component 306 includes pulleys 3061 respectively arranged on the outer sides of the rotating shaft 2121 and the retaining ring 304. The two pulleys 3061 are connected by a conveyor belt 3062. When the rotating shaft 2121 rotates, the pulley 3061 on the rotating shaft 2121 drives the conveyor belt 3062 to rotate synchronously, and the conveyor belt 3062 drives the pulley 3061 on the retaining ring 304 to rotate synchronously, thereby causing the retaining ring 304 to rotate and release the blockage of the discharge hole 303.

[0057] Furthermore, a second spring 307 is provided on the corresponding surface of the adjustment block 2123 and the storage box 210. When the clamping device 102 is reset, the adjustment block 2123 is driven to reset by the second spring 307.

[0058] Furthermore, a fixed plate 308 is provided on the guide column 2124, and a rope 309 is slidably provided on the fixed plate 308. One end of the rope 309 is connected to the vibration plate 208, and the other end is connected to the adjustment block 2123. When the conveying device 101 drives the clamping device 102 to fully reset, the vibration plate 208 on the clamping device 102 pulls the rope 309, and the rope 309 pulls the adjustment block 2123. The adjustment block 2123 slides along the direction of the rotating shaft 2121, so that the spiral groove 2125 on the adjustment block 2123 squeezes the push column 2126, causing the rotating shaft 2121 to rotate. At this time, the isolation plate 2122 rotates and expands, which makes it easier for the staff to take out the parts that have fallen into the storage box 210.

[0059] The air is compressed by the displacement of the ejector plate 206, so that the compressed air is gathered in the U-shaped tube 302. The blowing mechanism 3 drives the retaining ring 304 to rotate and releases the blockage of the discharge hole 303, so that the compressed air in the U-shaped tube 302 is discharged from the discharge hole 303, and the discharged air is used to blow the parts of the circuit board that are not firmly welded to the vibration plate 208. The degree of blockage of the discharge hole 303 by the retaining ring 304 can control the flow rate of the air discharge, and the direction of the air discharge is controlled by the extension part 305. It is suitable for different types of circuit board inspections.

[0060] The use process of the electronic component visual inspection mechanism provided by the present invention is as follows:

[0061] During use, the conveying device 101 drives the clamping device 102 to move, and the clamping device 102 moves synchronously with the circuit board and the vibration plate 208. The protrusion 209 on the vibration plate 208 first contacts the ejector pin 204, wherein the protrusion 209 is composed of multiple trapezoids. When the ejector pin 204 continuously contacts the protrusion 209, the ejector pin 204 is elastically moved downward and then up and down by the spring 1 207. The upward displacement of the ejector pin 204 does not return to the initial position, and the upward displacement is only a short distance from the inclined surface of the protrusion 209. At this time, the up and down displacement of the ejector pin 204 collides with the protrusion 209, causing the protrusion 209 to vibrate continuously, thereby causing the vibration plate 208 to vibrate synchronously. The vibration of the vibration plate 208 is transmitted to the clamping device 102, causing the circuit board to vibrate synchronously. Then, the microscope 301 is used for flat scanning inspection, so that when the circuit board is inspected for loosely welded parts, no physical damage to the circuit board is caused. The ejector pin 204 and the ejector plate 206 move downward, so that the air in the multiple inclined grooves is compressed into the U-shaped tube 302. Since there are multiple ejector pins 204 and the ejector plate 206, the pressure in the U-shaped tube 302 gradually increases. When the vibration plate 208 contacts the adjustment block 2123 and pushes it, the adjustment block 2123 moves along the rotating shaft 2121, and the spiral groove 2125 on the adjustment block 2123 squeezes the push column 2126. , so that the pushing column 2126 rotates synchronously with the rotating shaft 2121, and the rotating shaft 2121 rotates and drives the isolation plate 2122 to rotate synchronously, so that the isolation plate 2122 rotates and expands, and the pulley 3061 on the rotating shaft 2121 drives the conveyor belt 3062 to rotate synchronously, and the conveyor belt 3062 drives the pulley 3061 on the retaining ring 304 to rotate synchronously, thereby causing the retaining ring 304 to rotate and release the blockage of the discharge hole 303, and the compressed air in the U-shaped tube 302 is ejected from the discharge hole 303, and the ejected air blows away the parts of the circuit board that are not firmly soldered, so that the blowing and vibration cause the fallen parts to detach, and the detached parts first fall onto the vibration plate 208, and then pass through The wedge-shaped groove 211 on the vibration plate 208 acts as a buffer, and the parts slide along the direction of the wedge-shaped groove 211 and onto the surface of the receiving seat 203. Eventually, all the parts that fall off the circuit board will fall into the storage box 210 for collection. When the clamping device 102 is reset, the vibration plate 208 on the clamping device 102 pulls the rope 309, and the rope 309 pulls the adjustment block 2123. The adjustment block 2123 slides along the direction of the rotating shaft 2121, so that the spiral groove 2125 on the adjustment block 2123 squeezes the push column 2126, causing the rotating shaft 2121 to rotate. At this time, the isolation plate 2122 rotates and expands, which makes it convenient for the staff to take out the parts that fall into the storage box 210.
