For example, it is impossible to feedback the torque data when the nut is locked in real time. It can only rely on the personal judgment and experience of employees to ensure the tightening quality, which is not convenient for later quality traceability. In addition, since employees need to lock more than 8,000 nuts every day, the work intensity is high, and long-term work is prone to the hidden danger of abnormal locking quality, which increases the risk of errors and leads to serious instability in locking quality.

DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0063] It should also be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0064] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0065] See also Figure 1The embodiment of the present invention provides an automatic locking system for compressor nuts, including: a conveyor line body 100, which is used to transport and position products to be processed; the conveyor line body 100 includes a cache position and a visual photography position; a code scanning mechanism 200, which is arranged near the cache position, and is used to scan and identify the products to be processed entering the cache position, and enter the barcode information of the products to be processed; a visual mechanism 300, which is arranged near the visual photography position, and is used to take a photo of the products to be processed entering the visual photography position to detect whether the products to be processed are qualified; a locking mechanism 400, which is arranged on the side of the conveyor line body 100, and is used to lock the nuts to the products to be processed whose detection results are qualified, and perform a locking check. If the locking check is qualified, the locking parameters are obtained and bound to the barcode information; a display mechanism 500, which is connected to the code scanning mechanism 200 and the locking mechanism 400, and is used to receive and display the barcode information sent by the code scanning mechanism 200 and the locking parameters sent by the locking mechanism 400.

[0066] In this embodiment, an automated, information-based and intelligent production method for nut locking is realized through the locking mechanism 400, the code scanning mechanism 200, the visual mechanism 300 and the display mechanism 500, thereby solving the problem of uncontrollable quality of manually locked nuts and inconvenience for subsequent quality traceability, improving the overall quality of the product, and realizing closed-loop quality control of the entire process, thereby ensuring product quality and improving the product qualification rate.

[0067] Specifically, Figure 1 and Figure 2 As shown, the locking mechanism 400 includes: a vibrating disk 401, which is used to screen and sort the nuts; a nut sorting detector 402, which is arranged at the output end of the vibrating disk 401, and is used to detect whether the nuts are in place; a divider, which is arranged at the output end of the vibrating disk 401, and is used to push the nuts on the output end of the vibrating disk 401 to the suction position.

[0068] In this embodiment, the vibration disk 401 can effectively arrange the nuts neatly through vibration and convey them one by one to the next link. The nut distributor detector 402 is arranged at the output end of the vibration disk 401. Its function is to detect whether the nuts have accurately arrived at the specified position; if the nuts fail to arrive on time, the entire locking process may be interrupted. The distributor is also located at the output end of the vibration disk 401, but its main task is to accurately push the nuts output by the vibration disk 401 to the suction position. This step ensures that the nuts can be accurately placed in the position where the locking mechanism 400 can absorb them, preparing for the subsequent locking operation.

[0069] In summary, through the coordinated work of the vibration plate 401, the nut distribution detector 402 and the distributor assembly, the locking mechanism 400 can efficiently and accurately complete the tasks of nut screening, distribution and suction, and prepare for subsequent nut locking operations.

[0070] Furthermore, the locking mechanism 400 also includes: a nut suction detector 403, which is arranged close to the suction position and is used to detect whether there is a nut on the suction position and whether the nut suction is qualified; a locking device 404, which is used to suck the nut and lock the nut to the product to be processed; a nut rejection device 405, which is used to reject unqualified nuts; a distance sensor 406, which is used to detect the locking depth of the nut.

[0071] In this embodiment, the nut suction detector 403 is mainly responsible for detecting whether there is a nut on the suction position and evaluating whether the nut is correctly sucked. This step is crucial to ensure that the nut can be accurately sucked by the locking mechanism 400 and placed on the product to be processed. The locking device 404 is the core component of the locking mechanism 400. The locking device 404 is not only responsible for sucking the nut, but also responsible for accurately locking the nut to the product to be processed. For those nuts that are judged to be unqualified due to various reasons (such as unqualified nut suction or nut size mismatch or damage, etc.), the nut rejection device 405 will be responsible for rejecting them to prevent them from having an adverse effect on product quality.

[0072] The distance sensor 406 is used to accurately measure the locking depth of the nut, thereby ensuring that each nut can be locked to the correct position to achieve the expected tightening effect. This not only further improves the automation and intelligence level of the locking mechanism 400, but also significantly enhances its control and guarantee capabilities for the locking quality.

[0073] Furthermore, the automatic locking system of the compressor nut also includes: a product rejection mechanism 600, which is used to reject unqualified products to be processed; and an unqualified product line 700, which is used to cache unqualified products to be processed. In this embodiment, the product rejection mechanism 600 is used to reject products to be processed that are judged to be unqualified after being detected by the visual mechanism 300. Through accurate identification and rapid response, the product rejection mechanism 600 can effectively separate defective products from the production line to prevent them from continuing to enter the subsequent processing flow. In order to properly manage and handle the rejected unqualified products, the system has added an unqualified product line 700, which is responsible for receiving and caching all defective products (unqualified products to be processed) identified and rejected by the product rejection mechanism 600, so as to facilitate further analysis, repair or scrapping.

[0074] By adding a product rejection mechanism 600 and a defective product line 700, the automatic locking system of the compressor nuts not only achieves strict control of product quality, but also ensures the smooth progress of the production process, further enhancing its ability to control and ensure product quality.

[0075] See also Figure 3 , Figure 3A schematic flow chart of a method for automatically locking a compressor nut provided by an embodiment of the present invention, the method comprising steps S101 to S105:

[0076] S101, transporting the product to be processed to the cache position through the conveyor line;

[0077] S102, using the barcode scanning mechanism to scan and identify the product to be processed, inputting the barcode information of the product to be processed, and transmitting the barcode information to the display mechanism;

[0078] S103, conveying the product to be processed to a visual photography position through the conveyor line;

[0079] S104, using the visual mechanism to take a photo of the product to be processed on the visual photographing position to identify whether the product to be processed is qualified;

[0080] S105, locking the nut to the product to be processed with a qualified test result through the locking mechanism, and performing a locking verification. If the locking verification is qualified, the locking parameters are obtained and bound with the barcode information and transmitted to the display mechanism for display.

[0081] In this embodiment, first, the product to be processed is smoothly transported to a preset cache position (a work position in front of a work position, also called a waiting position) through a conveyor line. When the product to be processed arrives at the cache position, it is accurately scanned and identified by a barcode scanning mechanism. The barcode scanning mechanism reads and enters the barcode information of the product to be processed, and then transmits this information to the display mechanism in real time for display so that the operator can view and track it at any time. Next, the product to be processed is further transported to the visual photography position through the conveyor line. At the visual photography position, the product to be processed is photographed and identified by a visual mechanism, and the image analysis technology is used to detect whether the product to be processed is qualified. This step ensures that only qualified products will enter the subsequent lock and payment process.

[0082] Furthermore, for products with qualified test results, the locking mechanism will start to perform the locking operation of the nut. The locking mechanism will accurately absorb the nut and lock it to the specified position of the product to be processed. During the locking process, the locking mechanism will also perform a locking check to ensure that the nut is correctly and firmly locked. If the locking check is qualified, the locking mechanism will obtain and record the locking parameters, and then bind these parameters with the barcode information of the product and transmit them to the display mechanism for display.

[0083] This automatic locking method not only realizes the automation and intelligence of compressor nut locking, but also ensures the controllability and traceability of locking quality. This method greatly improves production efficiency, reduces the labor intensity of operators, and provides a strong guarantee for the standardization and high-quality production of compressor nut locking.

[0084] The barcode information of the product to be processed includes the product model, etc., and the locking parameters include locking depth, locking torque, time parameters and speed parameters, etc.

[0085] In one embodiment, if Figure 4 As shown, before the step S105, that is, before the step of locking the nut to the product to be processed with a qualified test result by the locking mechanism, steps S201 to S204 are included:

[0086] S201, screening and sorting nuts through a vibrating plate;

[0087] S202, detecting whether the nut is in place by a nut distribution detector;

[0088] S203, if it is detected that the nut is not in place, continue to screen and divide the materials;

[0089] S204: If it is detected that the nut is in place, the nut is pushed to the suction position through the distributor.

[0090] In this embodiment, the vibration plate is an automatic feeding device, which uses vibration and tilted plate surface to make the nuts move in a directional manner in the plate, so that the nuts can be transported to the next process in a specific direction and speed. In this process, the vibration plate also plays a screening role, which can remove defective nuts or nuts that do not meet the specifications. The nut distribution detector is usually a sensor or a photoelectric switch, so the nut distribution detector can also be a nut distribution detection photoelectric, which is used to detect whether the nut has reached the specified position. The suction position is a station set in the locking mechanism.

[0091] When the nut is transported by the vibrating plate to the vicinity of the detector, the nut distribution detector will send a signal indicating that the nut is in place. If the nut distribution detector does not detect that the nut is in place, it means that the nut may still be in the vibrating plate or there is a delay in the transportation process. At this time, the system will automatically continue the screening and distribution process of the vibrating plate until the nut is successfully delivered. When the nut distribution detector confirms that the nut is in place, the system will trigger the distributor to act. The distributor is a mechanical device used to push the nut from the current position to the suction position of the next process. The nut is sucked in the suction position and is ready to be placed on the product to be processed for locking.

[0092] In one embodiment, if Figure 5As shown, before the step S105, that is, before the step of locking the nut to the product to be processed with a qualified test result by the locking mechanism, steps S301 to S305 are also included:

[0093] S301, detecting whether there is a nut on the suction position by the nut suction detector;

[0094] S302, if it is detected that there is a nut on the suction position, the nut on the suction position is sucked by the locking device;

[0095] S303, detecting whether the nut suction on the locking device is qualified by the nut suction detector;

[0096] S304, if the nut suction is unqualified, the corresponding nut is transported to the nut rejection device for rejection through the locking mechanism;

[0097] S305: If the nut is qualified for suction, the corresponding nut is transported to the locking waiting position through the locking device.

[0098] In this embodiment, the nut suction detector is a high-precision sensor or photoelectric switch. Therefore, the nut suction detector can also be a nut suction detection photoelectric, which is used to detect whether there is a nut on the suction position. The detector can accurately determine whether the nut has been successfully placed on the suction position. Once the nut suction detector confirms that there is a nut on the suction position, the locking device will accurately move to the suction position and firmly adsorb the nut on the suction position through vacuum suction. After the nut is sucked by the locking device, the system will use the nut suction detector again to detect whether the nut is correctly sucked. This step can ensure that the nut will not fall off or be damaged during transportation, thereby avoiding problems during the locking process. If the nut suction detector finds that the nut is not correctly sucked (for example, due to insufficient suction, incorrect nut position, etc.), the system will trigger the locking mechanism to transport the nut to the nut rejection device. The nut rejection device removes unqualified nuts from the production line to avoid interference with subsequent processes. If the nut suction detector confirms that the nut has been correctly sucked, the locking device will transport the nut to the locking waiting position.

[0099] The locking waiting position is a temporary storage point set in the locking mechanism for storing nuts that are ready for locking. In this position, the nuts will wait for subsequent locking operations.

[0100] In one embodiment, in step S105, the lock payment verification includes step S401:

[0101] S401, detecting the locking depth of the nut by means of a distance sensor, and detecting the locking torque, time parameter and speed parameter by means of a locking device.

[0102] In this embodiment, the distance sensor can measure and control the locking depth of the nut in real time. In practical applications, the distance sensor is usually installed near the locking device or the nut installation position, and the locking depth is determined by measuring the distance the nut moves. A torque sensor is provided on the locking device for real-time measurement and monitoring of the torque generated during the locking process. The torque sensor can accurately measure the torque value required when the nut is tightened, thereby ensuring that the locking torque of the nut meets the preset requirements, which is crucial to prevent the nut from loosening and ensuring the fastening performance of the product. By monitoring the time parameters, abnormal situations in the locking process can be discovered and resolved in a timely manner. For example, too long locking time may mean that the nut is stuck or other problems. The speed parameter can reflect the working efficiency and performance of the locking device.

[0103] In summary, by accurately controlling the locking process of the nut through the distance sensor and the locking device, it can be ensured that the locking depth, locking torque, time parameters and speed parameters of the nut meet the preset requirements, thereby improving the assembly quality and consistency of the product.

[0104] In one embodiment, if Figure 6 As shown, in the step S105, the lock payment verification also includes steps S501 to S502:

[0105] S501, judging whether the locking depth, locking torque, time parameter and speed parameter are qualified;

[0106] S502. If one or more of the locking depth, locking torque, time parameter and speed parameter are unqualified, the locking verification is determined to be unqualified; if all of the locking depth, locking torque, time parameter and speed parameter are qualified, the locking verification is determined to be qualified.

[0107] In this embodiment, in this step, the system automatically collects and compares the locking parameters (including locking depth, locking torque, time parameters and speed parameters) generated during the locking process with the preset qualified standards. The system uses a built-in logical judgment mechanism to check whether these parameters meet the preset qualified thresholds one by one. For each parameter, the system will independently evaluate and record the evaluation results.

[0108] Based on the evaluation results of various parameters collected in step S501, the system will perform an overall lock verification determination.

[0109] If one or more of the locking depth, locking torque, time parameters and speed parameters are unqualified: the system will determine that the locking verification is unqualified. This means that there are abnormalities or non-standard conditions in the locking process, which may cause insufficient tightening performance of the nut or damage the product. At this time, the system may trigger an alarm mechanism and stop the current locking operation so that the operator can check and correct it. If all of the locking depth, locking torque, time parameters and speed parameters are qualified: the system will determine that the locking verification is qualified. This means that the locking process of the nut meets the preset standards and the tightening performance of the nut is guaranteed.

[0110] Through this process, the automatic locking system of the compressor nut can achieve precise control and verification of the locking quality, ensuring the assembly quality and safety of the product. At the same time, this also provides strong support for quality control and traceability during the production process.

[0111] In one embodiment, if Figure 7 As shown, the automatic locking method of the compressor nut also includes steps S601 to S603;

[0112] S601, if the locking check fails, the nut is transported to the nut rejecting device through the locking device;

[0113] S602, removing the nuts by the nut removing device;

[0114] S603, the product to be processed after the nuts are removed is removed to the unqualified product line through the product removal mechanism.

[0115] In this embodiment, when the locking inspection result shows unqualified, the system will automatically trigger the locking device to act, which is responsible for transporting the unqualified nut from the current position (which may be the locking waiting position or the locking completion position) to the nut removal device. This step ensures that the unqualified nut can be identified and removed in time to avoid interference with subsequent processes.

[0116] Nut rejection devices can use a variety of methods to reject nuts, such as mechanical clamping or magnetic attraction. No matter which method is used, the goal of the nut rejection device is to ensure that unqualified nuts can be removed quickly and accurately, and avoid contamination or damage to other products on the production line.

[0117] Furthermore, after the nuts are removed, the product to be processed (which is now lacking the correct nut fastening) needs to be identified and removed from the normal production line. This is achieved through a product rejection mechanism, which is responsible for transporting the product to be processed after the nuts are removed from the current location to the unqualified product line.

[0118] like Figure 8As shown, it is a schematic diagram of the fully closed-loop process of the automatic locking method of the compressor nuts. The product to be processed is transported to the cache position through the conveyor line body, the scanning mechanism scans the code of the product to be processed to identify the model, and transmits the acquired barcode information to the display mechanism for storage, and at the same time, the nuts are screened and divided by the vibration plate, and then the nut dividing detection photoelectric is used to detect whether there are nuts. If there are no nuts, the vibration plate continues to screen the nuts and divide them; if nuts are detected, the nuts are pushed to the suction position through the divider (such as the dividing cylinder), and the locking device starts to absorb the nuts required by the corresponding model. After the absorption is completed, the locking device moves up, and the nut absorption detection photoelectric is used to detect whether the absorbed nuts are qualified; if unqualified, the nuts are transported to the nut rejection device for nut rejection through the locking device; if the absorption is qualified, the nuts are transported to the locking waiting position through the locking device; then, the product to be processed is transported to the visual mechanism for shooting. Photograph the position for identification. If the photo is unqualified, the unqualified products to be processed will be transported to the product rejection mechanism, and then the unqualified products to be processed will be rejected to the unqualified product line for manual inspection; if the photo is qualified, the locking device will start the locking action. During the locking process, the locking depth will be detected by the distance sensor, and the locking torque, time parameters and speed parameters will be monitored and determined by the locking device at the same time. If one or more of the judgment results are unqualified, the nuts will be transported to the nut rejection device for nut rejection through the locking device, and the unqualified products to be processed will be transported to the unqualified product line for manual inspection through the product rejection mechanism; if all the judgment results are qualified, the locking parameters will be obtained, and then the locking parameters in the locking process will be bound to the barcode information obtained by the aforementioned scanning mechanism and stored on the display mechanism, so that employees can conduct quality traceability inquiries later. Through the closed-loop quality monitoring of the entire process, the equipment quality is guaranteed and the qualified rate of products is improved.
