Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, specifically to a visual inspection mechanism for surface-mount capacitor packaging. Background Technology

[0002] Surface mount capacitor packaging encapsulates capacitor chips, electrode leads, and other components in a miniaturized housing. It is widely used in various electronic devices to facilitate the later assembly and repair of electronic devices. In order to improve the quality of surface mount capacitor packaging, intelligent machine vision is used to replace human eyes for visual inspection, which can determine whether there are defects and integrity in the surface mount capacitor packaging.

[0003] For example, the patent disclosed in the prior art with publication number "CN211839082U" is entitled "A Visual Inspection Mechanism for Defective Capacitors." It discloses issuing corresponding commands to cause a rotating clamping mechanism to rotate accordingly, and then rotating with the turntable to the top visual inspection station. The visual camera at this station images the top of the solid-state capacitor and transmits the image to the visual processing system. Then, as the inspection turntable rotates, the solid-state capacitor sequentially passes through multiple side visual inspection stations. Each time it passes a side visual inspection station, the cylindrical surface of the solid-state capacitor actually rotates by 30°. Thus, after passing through multiple side visual inspection stations, the entire cylindrical surface of the solid-state capacitor can be captured by the visual cameras at each side visual inspection station, and the images are also transmitted to the visual processing system for analysis and comparison. Another example is the prior art... The patent disclosed in patent number "CN219745575U" is entitled "An Automatic Appearance Inspection Machine". It discloses that at least three sets of visual inspection mechanisms are set up. The three sets of visual inspection mechanisms are used to inspect the upper side, lower side and side of the product respectively. The visual inspection mechanism includes a CC camera and a light source. The CC camera and light source used to inspect the upper side are mounted on the slide of the Z-axis moving module. The CC camera and light source used to inspect the lower side are located on the side of the Y-axis module. The CC camera and light source used to inspect the side are located on the opposite side of the CC camera and light source used to inspect the lower side. In addition, the light source is equipped with a push cylinder for adjusting the position of the light source. By pushing the cylinder, the position of the light source can be adjusted, so that the CC camera can capture the appearance of the product more clearly, and the industrial control computer can make more accurate judgment of information.

[0004] In the aforementioned existing visual inspection mechanisms, the CC camera lens is exposed to the outside environment for extended periods, causing dust and impurities to accumulate on its surface. This dust and impurities interfere with image quality, thereby affecting the accuracy of subsequent visual inspections. Furthermore, it requires staff to periodically find and wipe the lens, increasing workload and slowing down the efficiency of the visual inspection mechanism. Therefore, we propose a surface-mount capacitor-encapsulated visual inspection mechanism to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a surface-mount capacitor-encapsulated vision inspection mechanism to solve the problems mentioned in the background art. In current vision inspection mechanisms on the market, the lens of the CC camera is exposed to the outside environment for a long time. As a result, dust and impurities will adhere to the surface of the CC camera lens, which will interfere with the image quality and affect the accuracy of subsequent vision inspection. In addition, the staff needs to find a wiping cloth regularly to wipe it, which increases the workload and makes the vision inspection mechanism inefficient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a visual inspection mechanism for surface mount capacitor packaging, comprising a support frame and two sets of sprocket assemblies mounted on its inner side via conveyor rollers, with a chain plate installed between the two sets of sprocket assemblies. A main support plate is fixed above the front side of the chain plate, and a second placement plate is installed on the rear side of the main support plate. A first placement plate is connected to the left side of the second placement plate. A first CCD industrial camera and a second CCD industrial camera are mounted sequentially from left to right above the support frame via a fixing bracket. A third CCD industrial camera is mounted on the rear side of the support frame via a fixing bracket. Protective components are attached to the lenses of the first, second, and third CCD industrial cameras. A first electric push rod is fixed to the right front side of the support frame, and a pusher plate is installed at the rear end of the first electric push rod.

[0007] Preferably, an auxiliary support plate is fixed to the left side of the main support plate, and the rubber pad above the auxiliary support plate is in contact with the bottom surface of the horizontal first placement plate.

[0008] Preferably, a first rotating rod is installed in a slot on the left side of the second placement plate, and the first placement plate is fixed through the outer side of the first rotating rod. The front end of the first rotating rod passes through the front side of the main support plate, and a second transmission gear is fixed to the outer side of the front end of the first rotating rod. A spiral spring is nested and connected to the outer side of the front end of the first rotating rod.

[0009] Preferably, a second rack assembly is fixed on the upper left side of the support frame, and the second rack assembly is meshed with a second transmission gear.

[0010] Preferably, the upper surface of the second placement plate has a slotted groove for a rotating plate and a rotating plate, and rotating plates are provided on both the front and rear sides of the rotating plate. The highest point of the rotating plate and the horizontally arranged rotating plate is flush with the highest point of the second placement plate. A vertical rod penetrating the bottom surface of the second placement plate is installed on the bottom surface of the rotating plate, and a first transmission gear is fixed on the lower outer side of the vertical rod.

[0011] Preferably, a second electric push rod is fixed to the rear side of the support frame and disposed below the front side of the third CCD industrial camera. The output end of the second electric push rod passes through the rear side of the support frame and is connected to the first rack assembly. The first rack assembly is connected to the first transmission gear at the corresponding position by moving back and forth.

[0012] Preferably, a second rotating rod is fixedly fixed inside the rotating plate, and the left end of the second rotating rod passes through the left side of the second placement plate and is connected to the outside of the first rotating rod through a bevel gear set.

[0013] Preferably, the outer sides of the lenses of the first CCD industrial camera, the second CCD industrial camera, and the third CCD industrial camera are all fitted with a sleeve plate, and one side of the sleeve plate is connected to an auxiliary sealing plate. A threaded rod is installed through the inside of the auxiliary sealing plate, and the other side of the auxiliary sealing plate is connected to the support frame. The protective component includes a cover wiping cloth that is in contact with the sleeve plate and is installed on the cover plate. A protrusion is fixed on the side of the cover plate away from the sleeve plate, and a protrusion is threaded through the outer side of the threaded rod. The width of the auxiliary sealing plate is equal to the width of the cover plate.

[0014] Preferably, a fixed frame is installed on the outer side of the auxiliary sealing plate, and an air storage bag and a compression plate are installed inside the fixed frame. A connecting frame is symmetrically installed on the outer side of the compression plate and is slidably connected to the through groove on the side of the fixed frame. The other end of the connecting frame is connected to the cover plate. A delivery pipe is symmetrically installed on the outer side of the air storage bag and is installed through the side of the fixed frame. One end of the delivery pipe is connected to an exhaust pipe installed in a groove on one side of the cover plate through a connecting hose. A row of inclined jet nozzles is installed on the outer side of the exhaust pipe.

[0015] Preferably, a photoelectric sensor is connected to the outer front end of the conveying roller.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the visual inspection mechanism with surface-mount capacitor encapsulation avoids external dust and impurities from adhering to the lens and interfering with image quality, thus avoiding affecting the accuracy of subsequent visual inspection. The specific details are as follows:

[0017] (1) By using the cover plate and the cover wiping cloth together, the lenses of the first CCD industrial camera, the second CCD industrial camera and the third CCD industrial camera can be sealed and covered when not in use, so as to avoid external dust and impurities from sticking to the lens and interfering with the image quality, and to avoid affecting the accuracy of the subsequent visual inspection, so that the first CCD industrial camera, the second CCD industrial camera and the third CCD industrial camera can perform visual inspection work well in the later stage. The rotation speed and stopping time of the conveyor roller can be determined by the photoelectric sensor. When the stopping time is longer than the preset time, the motor can be controlled by the microcontroller to drive the cover plate and the cover wiping cloth to move, so that the entire visual inspection mechanism can intelligently control the movement of the cover plate and the cover wiping cloth, eliminating the need for staff to regularly find the wiping cloth to wipe, reducing the workload and improving the efficiency of the visual inspection mechanism.

[0018] Furthermore, when the cover plate and the cover cleaning cloth move to seal and cover the lens, a row of inclined jet nozzles on the outside of the exhaust pipe can blow away impurities and dust on the lens surface, preventing more impurities and dust from sticking to the cover cleaning cloth, thus improving the recycling rate of the cover cleaning cloth.

[0019] Furthermore, when the cover plate and the cover cloth are moved to a position where the lens is not sealed, the outer side of the cover cloth can be covered by the auxiliary sealing plate to prevent external dust and impurities from falling on the cover cloth. This further protects the cover cloth when it is not in use and further improves the recycling rate of the cover cloth.

[0020] (2) When the second transmission gear on the outside of the first rotating rod moves to mesh with the second rack assembly, the second transmission gear and the first rotating rod can be automatically driven to rotate through the second rack assembly, thereby causing the first rotating rod and the first placement plate to rotate. The inspection piece on the first placement plate can be tilted and moved to the second placement plate, so that the inspection piece can be automatically flipped over, so that the second CCD industrial camera can perform visual inspection on the lower surface of the inspection surface without the need for an additional power source.

[0021] Furthermore, when the first rotating rod rotates, it drives two second rotating rods to rotate via a bevel gear set. In turn, the two second rotating rods drive two rotating plates to rotate, which in turn assists in pushing and positioning the inspection piece on the second placement plate. This ensures that the inspection piece is at the center of the rotating plate, so that the rotating plate can drive the inspection piece to rotate later. This facilitates the second CCD industrial camera to perform visual inspection of the side of the inspection piece, thereby improving the efficiency of visual inspection. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-10 The present invention provides the following technical solution:

[0035] Example 1: The surface-mount capacitor-encapsulated vision inspection mechanism in this example can seal and cover the lenses of the first CCD industrial camera 10, the second CCD industrial camera 11, and the third CCD industrial camera 12 when they are not in use. This prevents external dust and impurities from adhering to the lenses and interfering with image quality, thereby improving the accuracy of subsequent vision inspection. For the specific structure, please refer to the attached diagram. Figure 1 and appendix Figures 5-7As shown, the system includes a support frame 1 and two sets of sprocket assemblies 2 mounted inside it via conveyor rollers 22. A chain plate 3 is installed between the two sets of sprocket assemblies 2. A main support plate 4 is fixed above the front side of the chain plate 3, and a second placement plate 8 is installed on the rear side of the main support plate 4. A first placement plate 7 is connected to the left side of the second placement plate 8. A first CCD industrial camera 10 and a second CCD industrial camera 11 are mounted sequentially from left to right on the top of the support frame 1 via a fixing frame 13. A third CCD industrial camera 10 is mounted on the rear side of the support frame 1 via a fixing frame 13. Machine 12, and protective components are attached to the lenses of the first CCD industrial camera 10, the second CCD industrial camera 11, and the third CCD industrial camera 12. A first electric push rod 5 is fixed to the front right side of the support frame 1. A pusher plate 6 is installed at the rear end of the first electric push rod 5. A sleeve plate 141 is fitted on the outer side of the lenses of the first CCD industrial camera 10, the second CCD industrial camera 11, and the third CCD industrial camera 12, and one side of the sleeve plate 141 is connected to the auxiliary sealing plate 14. A threaded rod is installed through the interior of the auxiliary sealing plate 14. 142. The other side of the auxiliary sealing plate 14 is connected to the support frame 1. The protective assembly includes a cover wiping cloth 161 that is in contact with the sleeve plate 141, and the cover wiping cloth 161 is installed on the cover plate 16. A protrusion 162 is fixed on the side of the cover plate 16 away from the sleeve plate 141, and the protrusion 162 is threaded through the outer side of the threaded rod 142. The width of the auxiliary sealing plate 14 is equal to the width of the cover plate 16. A fixing frame 15 is installed on the outer side of the auxiliary sealing plate 14, and an air storage bag 151 and a compression plate 15 are installed inside the fixing frame 15. 2. A connecting frame 153 is symmetrically installed on the outer side of the extrusion plate 152 and is slidably connected to the through groove on the side of the fixed frame 15. The other end of the connecting frame 153 is connected to the cover plate 16. A conveying pipe 17 is symmetrically installed on the outer side of the air storage bag 151 and is installed through the side of the fixed frame 15. One end of the conveying pipe 17 is connected to the exhaust pipe 18 installed in the groove on one side of the cover plate 16 through a connecting hose. A row of inclined jet nozzles is installed on the outer side of the exhaust pipe 18. A photoelectric sensor 222 is connected to the outer front end of the conveying roller 22.

[0036] The rear ends of the two parallel threaded rods 142 can be connected via a chain assembly. This allows one threaded rod 142 to be connected to an external motor, and the threaded rod 142 next to the third CCD industrial camera 12 to the same external motor. A microcontroller controls the motor at the rear end of the threaded rod 142 to start, causing the motor to rotate the threaded rod 142. When the threaded rod 142 rotates, it moves the outer threaded protrusion 162 backward. This protrusion 162 then moves the cover plate 16 and the cover wiping cloth 161 backward. The cover plate 16 then moves the connecting frame 153 and the extrusion plate 152 backward. At this time, the external air supply mechanism supplies air to the air storage bladder 151 through a pipe above the air storage bladder 151. The pipe above the air storage bladder 151 and the exhaust... One-way valves are installed inside the air tubes 18. After the cover plate 16 and the cover wiping cloth 161 move backward, the lenses of the first rack assembly 91, the first CCD industrial camera 10, the second CCD industrial camera 11, and the third CCD industrial camera 12 are exposed, so that the first rack assembly 91, the first CCD industrial camera 10, the second CCD industrial camera 11, and the third CCD industrial camera 12 can be used for visual inspection in conjunction with the light source. After the cover wiping cloth 161 moves backward, it is always in sealed contact with the auxiliary sealing plate 14, so as to prevent external dust and impurities from falling on the cover wiping cloth 161 when it is not in use. This further protects the cover wiping cloth 161 when it is not in use and further improves the recycling rate of the cover wiping cloth 161.

[0037] After the entire visual inspection is completed, when the photoelectric sensor 222 detects that the stopping time of the conveyor roller 22 is longer than the preset time (photoelectric sensor 222 is existing technology and will not be described in detail here), the photoelectric sensor 222 transmits this signal to the microcontroller. The microcontroller controls the motor to rotate in the opposite direction, causing the motor to drive the threaded rod 142 to rotate in the opposite direction, as shown above. This drives the cover plate 16 and the cover wiping cloth 161 to move forward. At the same time, the cover plate 16 drives the connecting frame 153 and the extrusion plate 152 to move forward, so that the extrusion plate 152 extrudes the air storage bag 151. At this time, the gas in the air storage bag 151 is transported to the exhaust pipe 18 through the conveying pipe 17 and the connecting hose. The outer row of the exhaust pipe 18 is inclined. The air jet head blows air onto the lens surface, removing impurities and dust, preventing excessive accumulation of these substances on the cover cloth 161. This increases the reusability of the cover cloth 161. The cover cloth 161 then fits tightly against the underside of the sleeve plate 141, sealing the lens when not in use. This prevents the lens from coming into contact with external dust and impurities, which could affect the image quality later. This allows for intelligent control of the movement of the cover plate 16 and the cover cloth 161 within the entire vision inspection mechanism, eliminating the need for staff to periodically search for and wipe the cloth, reducing workload and improving the efficiency of the vision inspection mechanism. The material of the cover cloth 161 is the same as that of existing lens cleaning cloths.

[0038] Example 2: The visual inspection mechanism for surface-mount capacitor packages in this example, based on Example 1, can flip the inspection piece without using an additional power source. Furthermore, it can assist in positioning the inspection piece during flipping, facilitating subsequent rotational inspection and thus improving the overall efficiency of the visual inspection. See attached diagram for the specific structure. Figures 1-4 and appendix Figures 8-10As shown, an auxiliary support plate 41 is fixed to the left side of the main support plate 4, and the rubber pad above the auxiliary support plate 41 is in contact with the bottom surface of the horizontal first placement plate 7. A first rotating rod 20 is installed in a slot on the left side of the second placement plate 8, and the first placement plate 7 is fixed through the outer side of the first rotating rod 20. The front end of the first rotating rod 20 passes through the front side of the main support plate 4, and a second transmission gear 201 is fixed to the outer side of the front end of the first rotating rod 20. A spiral spring 202 is nested and connected to the outer side of the front end of the first rotating rod 20. A second rack assembly 19 is fixed to the upper left side of the support frame 1, and the second rack assembly 19 is meshed with the second transmission gear 201. A rotating plate 81 and a rotating plate 21 are provided in a slot inside the upper surface of the second placement plate 8, and the front and rear sides of the rotating plate 81 are provided with There is a rotating plate 21, a rotating plate 81, and the highest point of the horizontally arranged rotating plate 21 is flush with the highest point of the second placement plate 8. A vertical rod 82 is installed on the bottom surface of the rotating plate 81, penetrating the bottom surface of the second placement plate 8. A first transmission gear 83 is fixed on the lower outer side of the vertical rod 82. A second electric push rod 9 is fixed on the rear side of the support frame 1 below the front side of the third CCD industrial camera 12. The output end of the second electric push rod 9 penetrates the rear side of the support frame 1 and is connected to the first rack assembly 91. The first rack assembly 91 is connected to the first transmission gear 83 at the corresponding position by moving back and forth. A second rotating rod 211 is fixed through the inside of the rotating plate 21. The left end of the second rotating rod 211 penetrates the left side of the second placement plate 8 and is connected to the outer side of the first rotating rod 20 through a bevel gear set.

[0039] A robotic arm places the inspection piece onto the leftmost first placement plate 7. Then, a first CCD industrial camera 10 photographs the upper surface of the inspection piece. The image analysis module within the vision inspection mechanism then determines whether defects such as cracks or bubbles exist on the upper surface. Since this part is existing technology, it will not be described in detail here. Next, a motor drives the conveyor roller 22 to rotate, which in turn moves the sprocket assembly 2 and the chain plate 3. The chain plate 3 moves the first placement plate 7 to the right. When the second transmission gear 201 engages with the second rack assembly 19, the second rack assembly 19 drives the second transmission gear 201 and the first rotating rod 20 to rotate. At this time, the spiral spring 202 stores energy, and the first rotating rod 20 rotates the first placement plate 7 90°. The first placement plate 7 flips the inspection piece onto the second placement plate 8, thus automatically... The inspection piece is flipped over. Simultaneously, the first rotating rod 20 rotates, driving the second rotating rod 211 to rotate via two sets of bevel gears. The second rotating rod 211 drives the rotating plate 21 to rotate, and the rotating plate 21 rotates 90° to assist in positioning the inspection piece, so that the inspection piece is at the center of the rotating plate 81. When the second placement plate 8 moves directly below the second CCD industrial camera 11, the rotation of the sprocket assembly 2 stops. At this time, the second transmission gear 201 separates from the second rack assembly 19, and the first placement plate 7 is rotated in the opposite direction to reset by the stored force of the spiral spring 202. At this time, the rubber pad on the upper surface of the auxiliary support plate 41 is in contact with the bottom surface of the reset first placement plate 7, which ensures the stability of the reset first placement plate 7. The rotating plate 21 also rotates in the opposite direction to reset. Then, the second CCD industrial camera 11 performs visual inspection on the lower surface of the inspection piece.

[0040] Then, when the second placement plate 8 moves to the front of the third CCD industrial camera 12, the operation of the sprocket assembly 2 stops, and the second electric push rod 9 is activated. The second electric push rod 9 drives the first rack assembly 91 to move forward. The first rack assembly 91 drives the first transmission gear 83, the vertical rod 82, and the rotating plate 81 to rotate slowly. The rotating plate 81 drives the inspection piece above to rotate slowly. Then, the third CCD industrial camera 12 performs visual inspection of the side of the inspection piece. Next, when the second placement plate 8 moves to the rear of the first electric push rod 5, if the inspection piece on the second placement plate 8 is a qualified product, the second placement plate 8 continues to move to the right, causing the qualified product on the second placement plate 8 to fall onto the collection plate on the right. If the inspection piece on the second placement plate 8 is a defective product, the first electric push rod 5 is activated. The output end of the first electric push rod 5 drives the pusher plate 6 to move backward. The pusher plate 6 pushes the defective product on the second placement plate 8 onto the collection plate on the rear side. This operation is repeated to perform continuous visual inspection work, thereby completing a series of tasks.
