Description

A smart cleaning device for skids in a painting workshop Technical Field

[0001] This utility model relates to the field of automobile production technology, and in particular to an intelligent cleaning device for skids in a painting workshop. Background Technology

[0002] In painting workshops, roller lathe skids, as the core carriers for conveying workpieces, are key hubs for the efficient operation of the process. Their use and maintenance quality directly affect production efficiency and product quality. However, the traditional skid maintenance mode in painting workshops mainly relies on manual inspection and cleaning, which exposes significant shortcomings in terms of efficiency, quality, and environmental compliance.

[0003] On the one hand, manual cleaning presents significant challenges in terms of efficiency and cleanliness: manual cleaning of a single skid takes a very long time and is difficult to thoroughly remove paint residue, adhesive residue, and other contaminants from complex structures; on the other hand, manual intervention disrupts the skid management order: manual intervention in skid movement may lead to chaos in the skid buffer area, affecting the stability of the conveying system and consequently impacting the production cycle. Summary of the Invention

[0004] The main technical problem to be solved by this utility model is to provide an intelligent cleaning device for skids in painting workshops, which realizes real-time linkage between skid cleaning machine and conveyor line as well as automated status detection and cleaning, thereby improving the efficiency and quality of skid cleaning.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A smart cleaning device for skids in a painting workshop includes a skid conveyor line, a skid cleaning machine, and a linkage detection and control system;

[0007] The linkage detection and control system includes a control module and an identification and detection module, and the control module and the identification and detection module are connected to a network module.

[0008] The skid conveyor line includes a buffer area, a detection area, and a cleaning area. The identification and detection module is located in the detection area, and the skid cleaning machine is located in the cleaning area.

[0009] The following are further optimizations of the above technical solution by this utility model:

[0010] The identification and detection module includes a visual recognition unit and a weight detection unit. The visual recognition unit is used to identify and compare the shape of the skid, and the weight detection unit is used to detect and judge the weight of the skid. Both the visual recognition unit and the weight detection unit are electrically connected to the network module.

[0011] Further optimization: The control module includes a conveyor controller and a cleaning controller. The conveyor controller is electrically connected to the network module and the skid conveyor line. The cleaning controller is electrically connected to the network module, the conveyor controller, and the skid cleaning machine.

[0012] Further optimization: The network module is also electrically connected to a field operation station.

[0013] Further optimization: The network module includes multiple interconnected switches.

[0014] The present invention adopts the above technical solution and has the following beneficial effects:

[0015] 1. This utility model adopts the above-mentioned technical solution, which is ingenious in conception and reasonable in structure. It realizes the fully automatic operation of skid cleaning work through the dual guarantee of visual and weight detection. The real-time linkage between the skid cleaning machine and the conveyor line replaces the traditional manual inspection and cleaning of skids, thereby improving the efficiency and quality of skid cleaning.

[0016] 2. The fully automated skid status monitoring and cleaning mode reduces manual intervention, making the entire skid conveying and cleaning system operate more systematically and orderly.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As shown in Figures 1 and 2, a smart cleaning device for skids in a painting workshop includes a skid conveyor line 1, a skid cleaning machine 2, and a linkage detection and control system.

[0023] In this embodiment, both the skid conveyor line 1 and the skid cleaning machine 2 are commercially available models and belong to the prior art, which are well known to those skilled in the art, and will not be described in detail here.

[0024] The linkage detection and control system includes a control module 3 and an identification and detection module 4, which are connected to a network module 5.

[0025] In this embodiment, the present invention uses information technology to avoid the chaos and conveying blockage in the buffer area 101 caused by manual intervention in the movement of the skid 6, making the operation of the entire skid 6 more orderly and efficient, and ensuring the production cycle.

[0026] At the same time, it avoids operators from staying in confined spaces and humid environments for extended periods, reducing the risk of operators coming into contact with chemicals and thus ensuring the occupational safety of operators. This, in turn, allows the skid 6 to clean faster and with higher quality, ensuring production safety.

[0027] As shown in Figure 1, the skid conveyor line 1 includes a buffer area 101, a detection area 102 and a cleaning area 103. The identification and detection module 4 is set in the detection area 102 and the skid cleaning machine 2 is set in the cleaning area 103.

[0028] As shown in Figures 1 and 2, the identification and detection module 4 includes a visual identification unit 401 and a weight detection unit 402. The visual identification unit 401 is used to identify and compare the shape of the skid 6, and the weight detection unit 402 is used to detect and judge the weight of the skid 6. Both the visual identification unit 401 and the weight detection unit 402 are electrically connected to the network module 5.

[0029] In this embodiment, the shape of the skid 6 is identified by the visual recognition unit 401, and the weight of the skid 6 is detected by the weight detection unit 402. The state of the skid 6 is detected by both detections. Then, a signal indicating whether to clean is required is transmitted to the cleaning controller 302 via a network electrical connection. The cleaning controller 302 then issues a cleaning command to the skid cleaning machine 2 to complete the automated detection and cleaning process of the skid 6.

[0030] In this embodiment, the visual recognition unit 401 can be a visual camera that is available on the market, such as the MVGL-AC192G-40UC industrial area array camera produced by Dakang Industrial (Shenzhen) Co., Ltd.

[0031] The visual recognition unit 401 captures images using a camera and compares the captured images with the standard skid 6 shape.

[0032] In this embodiment, the weight detection unit 402 can use a commercially available weighing sensor, such as the CD-GD-GW model weighing module manufactured by TransPower Electronics Inc.

[0033] The weight detection unit 402 is used to detect the weight of the skid 6 and determine whether its weight is within the standard weight range.

[0034] In this embodiment, the shape of the skid 6 may vary depending on the different workpieces, and information such as the shape of different types of skids 6 can be recorded in the visual recognition unit 401.

[0035] Similarly, the corresponding weight range can be set on the controller according to different types of skis 6.

[0036] As shown in Figure 2, the control module 3 includes a conveying controller 301 and a cleaning controller 302.

[0037] In this embodiment, the conveyor controller 301 also has equipment monitoring function, which includes the entire working process of the skid conveyor line 1 and the skid cleaning machine 2 in real time monitoring. When an abnormality is detected, an alarm mechanism will be automatically triggered and corresponding recovery measures will be taken to ensure the operational stability of the entire intelligent cleaning device.

[0038] The conveyor controller 301 is electrically connected to the network module 5 and the skid conveyor line 1, and the cleaning controller 302 is electrically connected to the network module 5, the conveyor controller 301 and the skid cleaning machine 2.

[0039] In this embodiment, both the conveying controller 301 and the cleaning controller 302 are commercially available PLC controllers, such as the Siemens S7-1200 model PLC controller.

[0040] In this embodiment, the entire cleaning process of the skid 6 is fully automated by using both visual and weight detection. Each time the skid 6 enters the buffer area 101, it can promptly select the skids that need to be cleaned and transport them to the cleaning area 103 for cleaning.

[0041] This invention not only replaces the traditional manual inspection and cleaning mode, improving the efficiency and quality of cleaning work, but also avoids the problem of damage to the roller bed and workpiece caused by the long-term use of the abnormal skid 6, thus facilitating the maintenance of the skid 6 and the entire conveying system.

[0042] The network module 5 is also electrically connected to a field operation station 7.

[0043] In this embodiment, the on-site operation station 7 can manually control the skid conveyor line 1, the skid cleaning machine 2, and the entire linkage detection and control system, realizing a combination of manual and automatic control, which improves the stability of the entire process operation and the flexibility of control.

[0044] The network module 5 includes multiple interconnected switches 501.

[0045] In this embodiment, the painting information production workshop of an automobile company is usually equipped with multiple switches 501, which are connected by optical fibers to form a workshop network ring network.

[0046] In this embodiment, the setup of the workshop network ring network enables the formation of information transmission channels between various devices within the workshop.

[0047] In this embodiment, the conveying controller 301, the cleaning controller 302, the vision recognition unit 401, the weight detection unit 402, and the field operation station 7 all communicate with the switch 501.

[0048] Furthermore, this utility model can also be manually controlled through the on-site operation station 7, realizing a combination of manual and automatic operation, making the operation of this utility model more flexible and versatile, which not only greatly improves the stability of production, but also reduces the failure rate and maintenance costs of the equipment.

[0049] The process for automating the inspection and cleaning of the skid 6 using this invention is as follows:

[0050] In the first step, the skid conveyor line 1 transports the skid 6 in the buffer area 101 to the detection area 102. After the skid 6 arrives at the automatic detection station, the conveyor controller 301 receives the signal that the skid 6 has arrived and transmits the arrival signal to the vision recognition unit 401 and the weight detection unit 402 through the network module 5.

[0051] The second step is for the visual recognition unit 401 to take a picture of the skid 6 at the automatic detection station, compare the captured image with the standard shape in the database, and output the result.

[0052] If the shape of the skid 6 is abnormal from the standard shape, the visual recognition unit 401 sends an abnormal state signal to the cleaning controller 302.

[0053] The third step is for the weight detection unit 402 to weigh the slide 6 at the automatic detection station, detect the weight change of the slide 6 caused by the adhesion of the sprayed material, compare the weighed weight data with the standard weight range, and output the results.

[0054] If the weight of the skid 6 exceeds the standard weight range, the weight detection unit 402 sends an abnormal status signal to the cleaning controller 302.

[0055] Fourth, after receiving the data sent by the vision recognition unit 401 and the weight detection unit 402, the cleaning controller 302 determines whether to issue a cleaning instruction to the conveying controller 301 based on the transmitted data information.

[0056] Fifth step: After receiving the cleaning command from the cleaning controller 302, the conveyor controller 301 transfers the skid 6 to be cleaned to the cleaning area 103 via the skid conveyor line 1 to complete the cleaning.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
