If it is NG (No Good, unqualified), manual sorting is performed. This "semi-automatic" method still requires a certain amount of labor costs, and cannot meet the higher UPH (Units Per Hour) production indicators in terms of production efficiency.

[0016] When the deceleration photoelectric sensor senses the material tray, the line speed is reduced to a low speed;

[0017] When the photoelectric sensor senses the tray, the line stops and the tray is fixed and lifted.

[0018] The visual inspection module starts taking photos of the first material for a preset number of times and then inspects it. After the photos are taken, it moves to the next material and waits for the previous inspection result each time it takes a photo. At the same time, the inspection result data is stored and marked.

[0043] The equipment body controls the feed products to automatically pass through the code scanning position, detection position and picking position based on the control strategy, and performs efficient material detection in combination with the corresponding associated control process to achieve the replenishment of OK materials and the discharge of NG products.

[0044] In this embodiment, the host computer can be understood as a host computer control system, and the control strategy can be implemented using host computer software programming such as C#, C++ or other programming languages; it can also be implemented using PLC and other technologies, which is not limited here.

[0045] Reference Figure 2 In the example shown, the device body is also provided with a detection unit, a functional module, a material tray and a conveyor line body;

[0046] The detection unit includes a sensing device, a code scanning device and a detection device; the functional module includes a feed conveying module 10, a detection conveying module 11, an NG discharge conveying module 12, a discharge conveying module 13, an XZ axis module 14, a feed blocking cylinder, a position switching cylinder, a stop mechanism, a conveying line module, a vacuum platform lifting mechanism, a vacuum platform, a lifting cylinder, a visual detection module and an NG picking and feeding module; wherein the sensing device includes a feed sensing photoelectric, a deceleration photoelectric and an in-position photoelectric;

[0047] The material trays include a feed tray, a discharge tray, an OK tray and an NG tray.

[0048] It should be noted that the equipment body is also equipped with a loading product code reading camera 1, a loading tray code reading camera 2, a camera 2 light source, a mobile stop X-axis module, a tray conveyor belt, a mobile stop mechanism, a linear guide rail, a camera 1 position switching cylinder, a conveyor line width adjustment knob, an electronic pressure gauge, a vacuum solenoid valve, a Y-axis module, an NG / OK tray placement platform, a barcode scanner, a belt conveyor motor, an X-axis module, a Z-axis module, a forward detection camera 3, an oblique detection camera 4, a detection camera light source, a rotating R-axis motor module, a vision guidance camera 5 and a vacuum nozzle.

[0049] Furthermore, in order to realize the full-process automatic operation of the assembly line, when passing through the code scanning position, the corresponding associated control process specifically includes:

[0050] In the initial state, after the photoelectric induction of the feed is triggered, the feed tray is scanned;

[0051] Determine whether it is a positive detection. If so, move the material tray to the discharge area and wait after scanning the code;

[0052] After receiving the material request signal from the detection position, the line body rotates at high speed to deliver the material tray;

[0053] After sensing that the material tray has completely left, the code scanning position enters the initial state and enters the next round of process.

[0054] That is, the control process of the scanning position is to receive the incoming material tray and scan each material in the tray. Depending on the size of the material, the camera can scan 4 to 8 materials at a time. After each scan, the tray needs to move to the next scanning position. Take 3 scanning positions as an example:

[0055] In the initial state, after the feed induction photoelectric trigger, the feed blocking cylinder descends, the line body rotates, and the material tray enters the equipment line body;

[0056] After moving to the code scanning position 1, the cylinder fixes the tray and the camera scans the code;

[0057] After moving to the code scanning position 2, the cylinder fixes the material tray and the camera scans the code;

[0058] After moving to the code scanning position 3, the cylinder fixes the tray and the camera scans the code;

[0059] Move to the discharge waiting position;

[0060] After receiving the material request signal from the detection position, the line body rotates at high speed to send out the material tray;

[0061] After sensing that the material tray has completely left, the code scanning position enters the initial state and enters the next round of process.

[0062] The feed tray and discharge tray involved can be set independently based on the situation, or they can be the same tray, but the names of the trays are differentiated based on their different positions.

[0063] In this embodiment, when the detection bit is passed, the corresponding associated control process specifically includes:

[0064] In the initial state, when the material tray completely enters the detection position, the line speed is first reduced to medium speed;

[0065] When the deceleration photoelectric sensor senses the material tray, the line speed is reduced to a low speed;

[0066] When the photoelectric sensor senses the tray, the line stops and the tray is fixed and lifted.

[0067] The visual inspection module starts taking photos of the first material for a preset number of times and then inspects it. After the photos are taken, it moves to the next material and waits for the previous inspection result each time it takes a photo. At the same time, the inspection result data is stored and marked.

[0068] This cycle completes the material inspection of the entire tray;

[0069] The tray is then lowered and released;

[0070] After receiving the material request signal from the picking position, the line body rotates at high speed to deliver the material tray;

[0071] After sensing that the material tray has completely left, the detection position enters the initial state and enters the next round of process.

[0072] The control process of the above detection position is to detect the glue type of each material in the material tray, and take photos of multiple glue parameters from at least two angles according to the equipment requirements. The specific process is as follows:

[0073] In the initial state, the material tray enters the detection position very quickly, so the line speed should be reduced to medium speed first;

[0074] When the deceleration photoelectric sensor senses the material tray, the line speed is reduced to a low speed;

[0075] When the photoelectric sensor senses the tray, the line stops and the tray is fixed and lifted.

[0076] The visual inspection module starts with taking photos of the first material and takes two inspections. After the image acquisition is completed, it moves to the next material (waiting for the previous inspection result each time it takes a photo); the system stores and identifies the inspection result data.

[0077] This cycle completes the material inspection of the entire tray;

[0078] The tray is then lowered and released;

[0079] After receiving the material request signal from the picking position, the line body rotates at high speed to send out the material tray;

[0080] After sensing that the material tray has completely left, the detection position enters the initial state and enters the next round of process.

[0081] When passing through the picking position, the corresponding associated control process specifically includes:

[0082] When the deceleration photoelectric sensor senses the material tray, the line speed is reduced to a low speed;

[0083] Receive the test results of all materials on the tray;

[0084] If all materials in the tray are not NG, they will be directly moved to the discharge tray position;

[0085] If there is, when the photoelectric sensor senses the tray, the line will stop and the tray will be fixed and lifted;

[0086] According to the detection results of all materials on the tray, the NG picking and replenishing module moves to the first NG material position for visual positioning, and adjusts the position according to the positioning compensation to absorb the NG material;

[0087] Move to the top of the empty position of the NG tray and take photos to detect whether there is material. If there is an empty position, move to the NG tray for visual positioning, and put the NG material into the NG tray after adjusting the position according to the positioning compensation; if there is material at this position, move to the next position and take photos for detection until all the trays are inspected; if no empty position is found, it means that the NG tray is full, the operation is paused and an alarm is prompted;

[0088] The NG picking and replenishing module moves to the position where the OK material is located for visual positioning, and adjusts the position according to the positioning compensation to absorb the OK material. It moves to the top of the barcode scanner to scan the QR code of the material, then moves the return tray to take out the empty space of the NG material for visual positioning, and adjusts the position according to the positioning compensation to put the OK material into the tray.

[0089] Repeat the above steps of replenishing OK materials and sucking out NG materials until all the NG materials in the tray are picked out and replenished with OK materials.

[0090] It should be noted that, since the control process of the picking position is to pick out the materials with NG test results in the tray and replace them with OK materials, the picking position also has an NG tray for storing NG materials and an OK tray for storing OK materials that replace NG materials. The specific process is as follows:

[0091] In the initial state, the material tray enters the picking position very quickly, so the line speed should be reduced to medium speed first;

[0092] Receive the test results of all materials on the tray;

[0093] When the deceleration photoelectric sensor senses the material tray, the line speed is reduced to a low speed;

[0094] If all materials in the tray are not NG, they will be directly moved to the discharge tray position;

[0095] When the photoelectric sensor senses the tray, the line stops and the tray is fixed and lifted.

[0096] According to the detection results of all materials on the tray, the NG picking and replenishing module moves to the first NG material position for visual positioning, and adjusts the position according to the positioning compensation to absorb the NG material;

[0097] Move to the top of the empty position of the NG tray and take photos to detect whether there is material. If there is an empty position, move to the NG tray for visual positioning, and put the NG material into the NG tray after adjusting the position according to the positioning compensation; if there is material at this position, move to the next position and take photos for detection until all the trays are inspected. If no empty position is found, it means that the NG tray is full, the operation is paused and an alarm is prompted;

[0098] After picking out NG materials, it is necessary to replenish the OK materials on the return tray; the NG picking and replenishing module moves to the material position on the OK tray for visual positioning, and adjusts the position according to the positioning compensation to absorb the OK materials, moves to the top of the barcode scanner to scan the material QR code, and then moves the return tray to take out the empty space of the NG materials for visual positioning, and adjusts the position according to the positioning compensation to put the OK materials into the tray;

[0099] Repeat the above steps of replenishing OK materials and sucking out NG materials until all NG materials in the tray are picked out and replenished with OK materials;

[0100] Then the tray is lowered and released, and moves to the position to be discharged;

[0101] After receiving the material feeding request signal from the next station equipment, the line body rotates at medium speed to send out the material tray;

[0102] After sensing that the material tray has completely left, the picking position enters the initial state and enters the next round of process.

[0103] In this embodiment, the visual inspection part involved uses AI technology, and the recognition accuracy is greatly improved by pre-training with glue sample pictures; at the same time, the system can also set different mode parameters to be compatible with different detection requirements of customers, and can also create and use multiple tray recipes, so that the compatibility and efficiency of the equipment are greatly improved; in addition, the system can connect to the signals of the front-end dispensing equipment and the back-end glue curing equipment to realize the full-automatic operation of the whole assembly line, saving labor costs;

[0104] The labor cost has been greatly reduced. Currently, each device of the same type needs to be equipped with a quality inspector to re-inspect and perform operations such as refilling. After applying this solution, multiple devices can now be equipped with one person to replace NG material trays with OK material trays, and the labor cost can be reduced by about 80%. In addition, a single device can operate continuously, and the production capacity has also been greatly improved, which is about four times that of existing similar equipment.

[0105] The above solution drives the equipment body to automatically detect glue on the product tray online through the control strategy, and realizes the discharge of NG materials and the replenishment of OK materials based on the detection results, realizing fully automatic operation of the entire assembly line, and upgrading the existing "semi-automatic" to "fully automatic" mode, effectively improving production efficiency and reducing labor costs.

8. The method according to claim 7, characterized in that When the code scanning bit is passed, the corresponding associated control flow specifically includes: In the initial state, after the photoelectric induction of the feed is triggered, the feed tray is scanned; Determine whether it is a positive detection. If so, move the material tray to the discharge area and wait after scanning the code; After receiving the material request signal from the detection position, the line body rotates at high speed to deliver the material tray; After sensing that the material tray has completely left, the code scanning position enters the initial state and enters the next round of process.

9. The method according to claim 8, characterized in that When the detection bit is passed, the corresponding associated control flow specifically includes: In the initial state, when the material tray completely enters the detection position, the line speed is first reduced to medium speed; When the deceleration photoelectric sensor senses the material tray, the line speed is reduced to a low speed; When the photoelectric sensor senses the tray, the line stops and the tray is fixed and lifted. The visual inspection module starts taking photos of the first material for a preset number of times and then inspects it. After the photos are taken, it moves to the next material and waits for the previous inspection result each time it takes a photo. At the same time, the inspection result data is stored and marked. This cycle completes the material inspection of the entire tray; The tray is then lowered and released; After receiving the material request signal from the picking position, the line body rotates at high speed to deliver the material tray; After sensing that the material tray has completely left, the detection position enters the initial state and enters the next round of process.

10. The method according to claim 9, characterized in that When passing through the picking position, the corresponding associated control process specifically includes: When the deceleration photoelectric sensor senses the material tray, the line speed is reduced to a low speed; Receive the test results of all materials on the tray; If all materials in the tray are not NG, they will be directly moved to the discharge tray position; If there is, when the photoelectric sensor senses the tray, the line will stop and the tray will be fixed and lifted; According to the detection results of all materials on the tray, the NG picking and replenishing module moves to the first NG material position for visual positioning, and adjusts the position according to the positioning compensation to absorb the NG material; Move to the top of the empty position of the NG tray and take photos to detect whether there is material. If there is an empty position, move to the NG tray for visual positioning, and put the NG material into the NG tray after adjusting the position according to the positioning compensation; if there is material at this position, move to the next position and take photos for detection until all the trays are inspected; if no empty position is found, it means that the NG tray is full, the operation is paused and an alarm is prompted; The NG picking and replenishing module moves to the position where the OK material is located for visual positioning, and adjusts the position according to the positioning compensation to absorb the OK material. It moves to the top of the barcode scanner to scan the QR code of the material, then moves the return tray to take out the empty space of the NG material for visual positioning, and adjusts the position according to the positioning compensation to put the OK material into the tray. Repeat the above steps of replenishing OK materials and sucking out NG materials until all the NG materials in the tray are picked out and replenished with OK materials.
