Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and more specifically, to a visual detection device for bottom positioning recognition points. Background Art

[0002] A visual detection device for bottom positioning recognition points is a device that uses machine vision technology to detect the bottom positioning recognition points of products. Its main purpose is to ensure that the position, shape, size, color and other characteristics of the bottom positioning recognition points of products meet the preset standards, so as to ensure the accuracy and stability of products in subsequent production, assembly or use processes.

[0003] At present, most detection devices use conveyor belts to transport the parts to be inspected and achieve automatic detection. Another method relies on manual visual observation of the recognition points to make judgments and detections. However, both of these methods have significant drawbacks. Although the conveyor belt transportation method improves the detection efficiency to a certain extent, in actual operation, it faces many problems. In order to ensure that the parts to be inspected can be in a suitable position during transportation for subsequent accurate detection, a large number of fine-tuning devices need to be operated complexly. This process is not only cumbersome but also time-consuming and laborious. Even after the position adjustment is completed, it is necessary to ensure that the parts to be inspected can accurately fall into the detection position. More importantly, this method relies on laser alignment of the recognition points. Once the parts to be inspected are misaligned, it will directly lead to serious errors in the detection data, affecting the accuracy and reliability of the detection results. The method of directly relying on human eyes for judgment is extremely inefficient. The inspectors need to concentrate on observing the recognition points for a long time, which not only consumes a lot of time but also places extremely high requirements on the recognition experience of the personnel. The experience levels of different personnel vary greatly, which easily leads to subjectivity and uncertainty in the detection results and is difficult to ensure the consistency of the detection quality. In view of this, we propose a visual detection device for bottom positioning recognition points. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention designs an adjustment component, a control component and a table component. Place the product to be detected above the table component, squeeze the control component to adjust the driving component of the adjustment component. At this time, several adjustment components will move towards each other, squeeze the product to be detected, and make it move to the central position above the table component. At the same time, the driving component and the driven component complete docking, trigger the starting device in the table component, and then start the regulator and the vision detector, so that the vision detector detects the product to be detected located at the central position. When using this device, just place the product above the table component and then squeeze the control component to complete the precise adjustment of the product position and start the device for detection at the same time. Compared with the existing detection technology, in terms of operation, this device only needs to place the product above the table component and squeeze the control component to complete the position adjustment and start the detection, eliminating the complex operations of a large number of fine-tuning devices in the conveyor belt conveying method, and greatly simplifying the process; in terms of positioning, the adjustment components squeeze towards each other to accurately center the product, avoiding incorrect detection data caused by misalignment, and ensuring the accuracy of the detection position and the reliability of the result; in terms of detection, this device relies on mechanical automation, is not affected by personnel experience, avoids subjectivity and uncertainty, and ensures the consistency of detection quality.

[0017] 2. The present invention also designs an adjustment component and a vision detector. Place the product to be detected in the placement groove, squeeze the knob, and the downward movement of the knob will drive the rotating rod, the bearing and the driving rod connected to another bearing to move downward together. When the driving rod moves downward, it will drive the piston plate to move downward through the positioning frame. At this time, the piston plate will squeeze the air in the sealed shell along the conduit into the elastic telescopic sleeve. The elastic telescopic sleeve expands due to inflation, and then drives the four push plates to move, making the four push plates move towards each other and push the product to be detected to the center of the placement groove. At the same time, during the downward movement of the driving rod, the trigger block at its bottom will squeeze the control switch, and this action will cause the regulator to push the vision detector downward and turn on the vision detector, thus completing the detection of the product to be detected. Through simple pressing steps, the positioning of the product to be detected can be completed, and during the positioning process, the regulator will drive the vision detector downward to complete the detection of the product. This method reduces the operation difficulty of the device and ensures that the position of the product to be detected can be accurately adjusted each time, avoiding errors in detection data caused by the deviation of the product position.

[0018] 3. The present invention also designs a driven component and a connection component. After the extrusion knob pushes the product to be inspected to the center of the placement groove, the knob is rotated clockwise by 90 degrees. The rotation of the knob will drive the rotating rod, and then the transmission wheel will drive the driving rod to rotate synchronously. Since the driving rod has moved downward with the rotating rod before, at this time, the first gear and the second gear are engaged. In this state, the driving rod will drive multiple limit telescopic rods and the lead screw to rotate at the same time. During the rotation of the lead screw, it will move downward under the influence of the internal thread of the nut. Since the product to be inspected is located at the center inside the placement groove at this time, it is difficult for external air to enter the inner cylinder blocked by the product to be inspected. Therefore, when the sealing plate moves downward, a negative pressure will be formed between the blocked inner cylinder and the product to be inspected, thereby adsorbing the product to be inspected and further fixing it. This can avoid the position deviation of the product to be inspected due to external forces during the detection process, and further ensure the accuracy of the detection data of the device.

Among them, the vision detector 23 is located at the bottom of the regulator 22. By designing the adjusting assembly 12, the control assembly 15, and the table body assembly 11, the product to be detected is placed above the table body assembly 11, and the control assembly 15 is squeezed to adjust the driving assembly 17 of the adjusting assembly 12. At this time, several adjusting assemblies 12 will move towards each other, squeezing the product to be detected and moving it to the central position above the table body assembly 11. At the same time, the driving assembly 17 and the driven assembly 18 complete docking, triggering the starting device within the table body assembly 11, and then starting the regulator 22 and the vision detector 23, enabling the vision detector 23 to detect the product to be detected located at the central position. When using this device, just place the product above the table body assembly 11 and then squeeze the control assembly 15 to complete the precise adjustment of the product position and simultaneously start the device for detection. Compared with the existing detection technology, in terms of operation, this device only needs to place the product above the table body assembly 11 and squeeze the control assembly 15 to complete the position adjustment and start the detection, eliminating the complex operations of a large number of fine-tuning devices in the conveyor belt conveying method, and greatly simplifying the process; in terms of positioning, the adjusting assemblies 12 squeeze towards each other to accurately center the product, avoiding incorrect detection data caused by misalignment, and ensuring the accuracy of the detection position and the reliability of the results; in terms of detection, this device relies on mechanical automation, is not affected by personnel experience, avoids subjectivity and uncertainty, and ensures the consistency of the detection quality.

[0022] In an embodiment of the present invention, the upper part of the table component 11 is fixedly connected to four adjusting components 12, and the bottom ends of the four adjusting components 12 pass through the table component 11 and are connected to the same pressure component 13 in communication. The pressure component 13 is fixedly connected to the table component 11, the table component 11 is fixedly connected to the driving component 17, the inner wall of the table component 11 is fixedly connected to the mounting component 14, the inner wall of the mounting component 14 is fixedly connected to a plurality of driven components 18, the table component 11 is fixedly connected to the control component 15, the control component 15 is connected to the driving component 17 through the connecting component 16. The upper part of the detection frame 21 is fixedly connected to the regulator 22, the bottom end of the regulator 22 passes through the detection frame 21 and is fixedly connected to the vision detector 23, and the bottom end of the detection frame 21 is fixedly connected to the upper part of the table component 11. By designing the adjusting component 12 and the vision detector 23, the product to be detected is placed in the placement groove 112, and the knob 154 is squeezed. When the knob 154 moves downward, it will drive the rotating rod 152, the bearing 143 and the driving rod 171 connected to another bearing 143 to move downward together. When the driving rod 171 moves downward, it will drive the piston plate 132 to move downward through the positioning frame 133. At this time, the piston plate 132 will squeeze the air in the sealing shell 131 along the conduit 124 into the elastic telescopic sleeve 122. The elastic telescopic sleeve 122 expands due to inflation, and then drives the four push plates 123 to move, so that the four push plates 123 move towards each other, and the product to be detected is pushed to the center of the placement groove 112. At the same time, during the downward movement of the driving rod 171, the trigger block 172 at its bottom will squeeze the control switch 114. This action will cause the regulator 22 to push the vision detector 23 downward and turn on the vision detector 23, so as to complete the detection of the product to be detected. Through simple pressing steps, the positioning of the product to be detected can be completed, and during the positioning process, the regulator 22 will drive the vision detector 23 to move downward to complete the detection of the product. This method reduces the operation difficulty of the device, and at the same time ensures that the position of the product to be detected can be accurately adjusted each time, avoiding errors in detection data caused by the deviation of the product position.

[0023] In an embodiment of the present invention, the table component 11 includes a detection table 111. A placement groove 112 is formed above the detection table 111. A reinforcing rib 113 is fixedly connected below the detection table 111. A control switch 114 is arranged at the middle position of the reinforcing rib 113. A through hole 115 is formed below the inner wall of the placement groove 112. The upper part of the detection table 111 is fixedly connected to the bottom end of the detection frame 21. The installation component 14 is fixedly connected in the through hole 115. The control switch 114 is electrically connected to the regulator 22 and the vision detector 23. The adjustment component 12 includes a fixed frame 121. An elastic telescopic sleeve 122 is fixedly connected inside the fixed frame 121. One end of the elastic telescopic sleeve 122 is fixedly connected to a push plate 123. By designing the driven component 18 and the connection component 16, after the inspection product to be inspected is pushed to the center of the placement groove 112 by squeezing the knob 154, the knob 154 is rotated clockwise by ninety degrees. The rotation of the knob 154 will drive the rotating rod 152, and then the transmission wheel 163 will synchronously drive the driving rod 171 to rotate. Since the driving rod 171 has moved downward with the rotating rod 152 before, at this time, the first gear 173 and the second gear 187 are engaged. In this state, the driving rod 171 will drive a plurality of limit telescopic rods 186 and the lead screw 184 to rotate at the same time. During the rotation of the lead screw 184, it will move downward under the influence of the internal thread of the nut 185. Since the inspection product to be inspected is located at the center inside the placement groove 112 at this time, it is difficult for external air to enter the inner cylinder 181 blocked by the inspection product to be inspected. Therefore, when the sealing plate 182 moves downward, a negative pressure will be formed between the blocked inner cylinder 181 and the inspection product to be inspected, thereby adsorbing the inspection product to be inspected and further fixing the inspection product to be inspected. This can avoid the position deviation of the inspection product to be inspected due to external force during the detection process, and further ensure the accuracy of the detection data of the device; The other end of the elastic telescopic sleeve 122 passes through the fixing frame 121 and is connected to the conduit 124. The lower part of the fixing frame 121 is fixedly connected to the upper part of the detection platform 111. The other end of the conduit 124 is connected to the pressure component 13. The push plate 123 is located in the placement groove 112. The pressure component 13 includes a sealing shell 131. A piston plate 132 is slidably connected in the sealing shell 131. A positioning frame 133 is fixedly connected above the piston plate 132. The sealing shell 131 is fixedly connected above the reinforcing rib 113. The sealing shell 131 is connected to four conduits 124. After the inspection is completed, the hand holding the knob 154 is released while keeping the pressure on the knob 154. The knob 154 will rotate on the coil spring. 153 rotates and resets under the action of the elastic force. At this time, the sealing plate 182 in the inner cylinder 181 will also reset accordingly, releasing the adsorption and fixation of the product. Subsequently, the squeezing of the knob 154 is released, and the elastic telescopic sleeve 122 will gradually reset and return the air inside it to the sealing shell 131. During this process, the positioning frame 133 will push the driving rod 171 and the rotating rod 152 to reset. In this way, when using the device, it is only necessary to simply keep the knob 154 in the position for 1 to 3 seconds after the detection is completed, and then release the knob 154 to take out the detected product for subsequent detection. This method reduces the difficulty of using the device and effectively improves the detection efficiency through the automatic reset mechanism.

The sleeve 151 is fixedly connected above the detection platform 111, and the rotating rod 152 is transmission-connected to the driving assembly 17 through the connecting assembly 16. By arranging multiple inner cylinders 181 in the outer cylinder 141, when detecting irregular products, only the parts of the inner cylinder 181 completely covered by the products can be adsorbed and fixed, and the multiple inner cylinders 181 do not interfere with each other, so that the device can effectively fix and detect products of different specifications and sizes, thereby improving the applicability of the device.

[0025] As another embodiment of the present invention, the connection assembly 16 includes two limit sleeves 161 and two transmission wheels 163. The two limit sleeves 161 are fixedly connected through a connecting plate 162, and the two transmission wheels 163 are drivingly connected through a transmission belt 164.

The inner cylinder 181 is fixedly connected inside the outer cylinder 141. Since the lower part of the first gear 173 is a bevel surface and the upper part of the second gear 187 is a bevel surface, the first gear 173 can be stably docked with the second gear 187 after moving downward, avoiding the situation that the first gear 173 and the second gear 187 are difficult to mesh due to misalignment, which affects the use efficiency.

[0026] Working principle: This embodiment provides a bottom positioning recognition point vision detection device. When in use, the product to be detected is placed above the table body assembly 11, and the control assembly 15 is squeezed to adjust the driving assembly 17 of the adjusting assembly 12. At this time, several adjusting assemblies 12 will move towards each other and squeeze the product to be detected, so that it moves to the central position above the table body assembly 11. At the same time, the driving assembly 17 and the driven assembly 18 are docked, triggering the starting device in the table body assembly 11, and then starting the regulator 22 and the vision detector 23, so that the vision detector 23 detects the product to be detected located at the central position. When using this device, just place the product above the table body assembly 11 and then squeeze the control assembly 15 to complete the precise adjustment of the product position and start the device to detect the product at the same time; During detection, place the product to be detected into the placement groove 112, and squeeze the knob 154. When the knob 154 moves downward, it will drive the rotating rod 152, the bearing 143, and the driving rod 171 connected to the other bearing 143 to move downward together. When the driving rod 171 moves downward, it drives the piston plate 132 to move downward through the positioning frame 133. The piston plate 132 squeezes the air in the sealing shell 131 into the elastic telescopic sleeve 122 along the conduit 124. The elastic telescopic sleeve 122 expands due to inflation, and then drives the four push plates 123 to move towards each other, pushing the product to be detected to the center of the placement groove 112. At the same time, during the downward movement of the driving rod 171, the trigger block 172 at its bottom will squeeze the control switch 114, causing the regulator 22 to push the vision detector 23 downward and turn it on, thus completing the detection of the product to be detected; After squeezing the knob 154 to push the product to be detected to the center of the placement groove 112, rotate the knob 154 clockwise by 90 degrees. The rotation of the knob 154 drives the rotating rod 152, and then the transmission wheel 163 synchronously drives the driving rod 171 to rotate. Since the driving rod 171 has moved downward with the rotating rod 152 before, at this time, the first gear 173 and the second gear 187 are engaged. In this state, the driving rod 171 drives a plurality of limit telescopic rods 186 and the lead screw 184 to rotate simultaneously. During the rotation of the lead screw 184, it moves downward under the influence of the internal thread of the nut 185. At this time, the product to be detected is located in the center of the placement groove 112, and it is difficult for external air to enter the inner cylinder 181 blocked by it. Therefore, when the sealing plate 182 moves downward, a negative pressure will be formed between the blocked inner cylinder 181 and the product to be detected, thereby adsorbing the product to be detected; After the detection is completed, while maintaining the pressure on the knob 154, release the hand holding the knob 154. The knob 154 will rotate and reset under the action of the elastic force of the coil spring 153. At this time, the sealing plate 182 in the inner cylinder 181 resets, releasing the adsorption and fixation of the product. Subsequently, release the squeeze on the knob 154, and the elastic telescopic sleeve 122 will gradually reset and return the air inside it to the sealing shell 131, and then push the driving rod 171 and the rotating rod 152 to reset through the positioning frame 133. In this way, when using this device, only need to simply hold the position of the knob 154 for 1 - 3 seconds after the detection is completed, and then release the knob 154, then the detected product can be taken out for subsequent detection.
