Description

Technical Field

[0001] The invention belongs to the field of printed surface detection, and in particular relates to a device and a method for detecting the printed surface in a product material tube. Background Art

[0002] During the production process, electronic components such as network transformers and power transformers will be printed on their surfaces as a mark. The printed surface needs to ensure the integrity and integrity of the content, so the printed surface needs to be inspected. At present, the printed surface inspection is generally carried out one by one, and the good and bad products are manually classified. Equipment with a higher degree of automation also has a mechanism for automatically classifying good and bad products. However, this inspection method is still inefficient. If a large number of inspections are encountered, it will take a lot of time. Therefore, it is necessary to conduct an overall inspection of the printed surface of the material tube.

[0003] Since traditional testing is performed one by one, the corresponding feeding mechanism of the testing equipment also feeds one by one. If the entire material pipe needs to be fed, the existing feeding mechanism cannot meet the demand. At the same time, the traditional feeding mechanism does not have a mechanism to block the material at the feeding end. If the testing equipment does not operate smoothly or the feeding mechanism has problems, it is easy to cause product accumulation at the feeding end.

[0004] The detection mechanism is the core mechanism in the process of printing surface detection. The existing detection mechanism is generally fixed. During the detection process, the product to be detected is transported to the bottom of the detection component by a conveyor belt or the detection component is moved for detection. The method of transporting the product to be detected by a conveyor belt is inefficient and cannot meet the requirements of overall material tube detection. The detection method of moving the detection component will shake the detection component product because the detection component moves left and right, thereby affecting the detection effect.

[0005] The transport mechanism is a component used to transport the inspected material tubes during the printing surface inspection process and to classify the good or bad products. Most of the existing transport components have complex structures and unstable transport, which easily leads to deviations in the transport results. Therefore, it cannot meet the needs of overall transport of the material tubes. Summary of the invention

[0018] Step 2: The test starts. The feeding stopper assembly opens the feeding chute. The feeding translation cylinder drives the pushing plate through the pushing support vertical plate to push the corresponding material tube to be tested out of the feeding chute.

[0054] When the material tube feeding mechanism 2 is working, the material tube to be tested is placed between the material blocking space 20403 formed between the mounting plate 20401 and the two material blocking plates 20402, waiting for feeding. By adjusting the width of the mounting plate 20401, the number of material tubes in a row can be adjusted; if the width of the mounting plate 20401 is adjusted, the size of the connecting plate 203 used to install the mounting plate 20401 needs to be adaptively adjusted. When the mechanism is in the non-feeding state, the piston rod end of the material blocking cylinder 2061 is in an extended state, and the material feeding blocking block 2063 blocks the front of the feeding trough 205 to block the position of the material tube. After the material loading starts, the piston rod end of the material stopper cylinder 2061 retracts, pulling the connecting block 2062 to move upward; since the material loading stopper block 2063 is connected to the inner wall of the mounting groove 204021 and the connecting groove 20621 through the first rotating shaft 2064 and the second rotating shaft 2065, respectively, during the upward movement, the second connecting section 20633 of the material loading stopper block 2063 cannot be displaced, and will rotate relative to the first rotating shaft 2064, and the first connecting section 20632 of the material loading stopper block 2063 will also rotate relative to the second rotating shaft 2065, thereby driving the material stopper section 20631 to rotate away from the material loading trough 205. The material loading translation cylinder 208 works, driving the push plate 210 to move through the push support vertical plate 209, pushing the material pipe located at the bottom layer toward the material loading trough 205, and finally pushing a row of material pipes out of the material loading trough 205 to achieve material loading. During the pushing process of the push plate 210, the material tube on the upper layer will fall onto the push plate 210. After the pushing is completed, the piston rod end of the feeding lifting cylinder 207 extends to lift the material tube on the pushing plate 210; the feeding translation cylinder 208 works to drive the pushing plate 210 back to the initial position; the piston rod end of the feeding lifting cylinder 207 retracts, and the material tube naturally falls to the lowest layer of the vertical plate assembly 204, and the entire mechanism returns to the initial position.

[0055] When the moving detection mechanism 3 is working, the material tube moving detection panel 306 needs to be moved to the side of the material feeding trough 205 of the material tube feeding mechanism 2 . The material tube to be inspected pushed out by the feeding trough 205 of the material tube feeding mechanism 2 is displaced toward the material tube moving detection panel 306, and the material tube to be inspected pushes the check block 30672 of the check assembly 3067 to rotate in the check installation slot 30671, and rotates to the inside of the check installation slot 30671; after the material tube to be inspected is translated between the fixed stop block 3063, the movable stop block 3064 and the edge stop block 3066, the check block 30672 rotates in the check installation slot 30671, and the check block 30672 is re-installed outside the check installation slot 30671 to block the material tube to be inspected, and the stop block driving cylinder 3065 drives the movable stop block 3064 to displace, and the material tube is positioned by the fixed stop block 3063, the movable stop block 3064, the edge stop block 3066 and the check assembly 3067. Subsequently, the material tube moving detection panel 306 is moved to between the CCD detection components 303 through the moving detection horizontal moving module 302, and the piston rod end of the translation stopper cylinder 3042 of the moving detection stopper component 304 is extended to perform secondary positioning of the material tube to be detected; the detection light source 30326 of the light source component 3032 is turned on, and the detection camera 30315 is turned on to detect the material tube to be detected. After the detection, the material tube is transported to the subsequent process.

[0056] The material tube handling mechanism 4 is used to classify the material tubes that have been inspected into good and bad products. Before classification, the material tubes that have been inspected will be transported to the bottom of the material tube handling mechanism 4 by the mobile inspection mechanism 3. When the mechanism is working, the material tube handling horizontal moving module 403 and the material tube handling vertical moving module 405 are displaced in the lateral and longitudinal directions, thereby driving the material tube clamping jaws 410 to move above the material tube that has been inspected. The clamping jaw cylinder 409 is a double-headed cylinder. When the clamping jaw cylinder 409 works, it drives the two material tube clamping jaws 410 to move in opposite directions. When the material tube handling vertical moving module 405 is running, it drives the two material tube clamping jaws 410 to move to both sides of the material tube that has been inspected. When the clamping jaw cylinder 409 works, it drives the two material tube clamping jaws 410 to move in opposite directions to clamp the material tube that has been inspected. Subsequently, the material tube transporting horizontal moving module 403 and the material tube transporting vertical moving module 405 drive the clamped material tube that has completed the inspection to move to the top of the defective material tube receiving mechanism 5 or the good material tube conveying mechanism 6, and put down the material tube, thus completing the classification and transportation of the material tube.

[0057] The good material tube conveying mechanism 6 of the present invention drives the conveying roller 603 to rotate through the roller drive motor 605, thereby driving the conveying belt to run to complete the conveying of the good material tube.

[0058] The first photoelectric sensor 3069, the second photoelectric sensor 607 and the material feeding detection optical fiber 211 provided in the detection device of the present invention are used to detect whether there is a material tube at each position. If combined with the automatic control program, automatic operation of each position can be realized.

[0059] The present invention also discloses a method for detecting the printed surface inside a product material tube, which is implemented by the product material tube printed surface detection device, and comprises the following steps:

[0060] Step 1: Place the material tube to be inspected between the two sets of the vertical plate assemblies 204, close the material feeding chute 205 by the material feeding stop assembly 206, and move the material tube movement detection panel 306 to one end close to the material tube feeding mechanism 2 by moving the detection horizontal moving module 302;

[0061] Step 2: Testing starts. The material loading and blocking assembly 206 opens the material loading chute 205. The material loading translation cylinder 208 drives the material pushing plate 210 to push the corresponding material tube to be tested out of the material loading chute 205 through the material pushing support vertical plate 209.

[0062] Step 3, the material tube to be tested pushed out by the loading chute 205 is displaced toward the material tube moving detection panel 306, the material tube to be tested pushes the check block 30672 of the check assembly 3067 to rotate in the check installation slot 30671, the material tube to be tested is translated to between the fixed material block 3063, the movable material block 3064 and the edge material block 3066, the check block 30672 rotates in the check installation slot 30671, and the check block 30672 is extended to the outside of the check installation slot 30671 to block the material tube to be tested, the material block driving cylinder 3065 drives the movable material block 3064 to move, and the material tube is positioned by the fixed material block 3063, the movable material block 3064, the edge material block 3066 and the check assembly 3067;

[0063] Step 4: The material tube moving detection panel 306 is moved to between the CCD detection components 303 through the moving detection horizontal moving module 302, the moving detection material blocking component 304 performs secondary positioning on the material tube to be detected, the detection light source 30326 of the light source component 3032 is turned on, and the detection camera 30315 is turned on to detect the material tube to be detected;

[0064] Step 5. After the inspection is completed, the material tube clamping claw 410 of the material tube transporting mechanism 4 is moved to the top of the material tube that has been inspected through the material tube transporting horizontal moving module 403 and the material tube transporting vertical moving module 405, and the claw cylinder 409 drives the two material tube clamping claws 410 to open. After clamping the material tube that has been inspected, the material tube clamping claw 410 is closed. If the material tube is a defective product, the material tube clamping claw 410 is moved to the defective material tube receiving mechanism 5 under the action of the material tube transporting horizontal moving module 403 and the material tube transporting vertical moving module 405 and the material tube is placed in the defective material tube receiving mechanism 5. If the material tube is a good product, the material tube clamping claw 410 is moved to the top of the good material tube conveying mechanism 6 under the action of the material tube transporting horizontal moving module 403 and the material tube transporting vertical moving module 405, and the good material tube conveying mechanism 6 runs to convey the material tube to the subsequent process.

[0065] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
