[0002] With the development of relevant technologies of smart factories, more and more equipment processing manufacturers choose to use spray robots to spray the exterior and interior surfaces of automobiles. Spray robots can effectively improve spraying efficiency, paint utilization, stabilize paint film quality, reduce sewage and paint residue treatment, and reduce environmental pollution.

[0003] In the process of building a smart factory, equipment manufacturers need to debug the spraying robot on site. Among them, the spray width of the spraying robot is one of the most important debugging aspects. For spray width debugging, it is generally done by placing a vertical plate on the production line, using the spraying robot to spray the plate, and then measuring the spray width, so as to debug the spray pressure or flow of the spraying robot based on the actual measurement data of the spray width.

[0004] However, the above spray width debugging method has at least the following problems: First, the above plate is difficult to be placed on the production line quickly and stably, and the debugging efficiency is low. Second, the above plate can generally only test the spray width of the spray robot's spray gun when spraying in a horizontal posture, and cannot test the spray width of the spray robot's spray gun when it is not horizontal (for example, tilted spraying or inverted spraying), resulting in the measured spray width being unable to fully reflect the spray width of the spray robot during actual work, which also leads to poor reliability of the debugging results.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0034] In the description of this application, it should be noted that the terms used, such as "top surface" and "bottom surface", refer to the fact that the debugging tool for the spray robot of this application in the use state has the top surface facing upward and the bottom surface facing downward; the terms used, such as "first" and "second", are only used to distinguish the expressions, and do not indicate or imply that they have a difference in importance or order. The use of the above terms is only to facilitate a clear and simple description of the technical solution of this application, and cannot be understood as a limitation of this application.

[0035] In order to facilitate relevant technical personnel to have a clearer and more accurate understanding of the technical solution of the present application, the test method of the spray width in the existing related technology is first described in more detail below.

[0036] In the process of equipment processing manufacturers building smart factories, for example, in the process of vehicle manufacturing companies building automatic spraying workshops, after the relevant infrastructure and equipment are installed, the spraying robot needs to be debugged. The spray width of the spraying robot is one of the most important debugging aspects.

[0037] In an automatic spraying workshop, a plate is generally placed in a vertical state on the spraying production line first. For example, the plate can be fixed on the production line by a clamp, a blocking block, etc., and then the spraying robot is controlled to spray the plate at a preset spraying distance. After the spraying is completed, the plate is removed and the spray width is measured according to the spraying conditions on the plate.

[0038] However, first, during the debugging process, the location of the fixtures, blocking blocks and other fixed structures needs to be set in combination with the form of the production line (or the actual structure). For example, on a track-type production line, it is generally necessary to place the fixture on the track or use the track to install the fixture. It is likely that the size of the track will not match the size of the fixture (or the track structure is not convenient for arranging the fixture). Therefore, the debugging personnel need to select appropriate fixtures according to the actual production line structure or use other methods (such as straps, blocking blocks, etc.) to fix the board. In this way, the placement process of the board is inconvenient, and it is difficult to quickly and stably place the board on the production line, resulting in low debugging efficiency.

[0039] Second, since the existing plate bodies are generally placed on the production line in a vertical form, the spray width of the spray gun of the spray robot can only be tested when spraying in a horizontal posture. And since the parts to be sprayed (for example, the body, the door, etc.) generally have multiple surfaces that need to be sprayed, for example, during the spraying process of the inner surface of the body, surfaces with various angles need to be sprayed, this requires the spray gun of the spray robot to spray in a non-horizontal posture (for example, tilted, inverted) during the normal spraying process. The spray width tested by the spray gun of the spray robot in a horizontal posture cannot guarantee that the spray gun of the spray robot can also have a corresponding spray width in other postures. For example, when the spray gun is rotated from a horizontal state to an inverted and slightly tilted state, its air pipe and paint liquid pipe may change to a certain extent (for example, bend, extend, etc.), so that its spray width changes. In other words, the existing debugging scheme only measures the spray width of the spray gun in a horizontal posture, and cannot guarantee that its debugging results can be reliably applied to spray guns in other postures.

[0040] In view of this, the present application provides a new solution, namely, a debugging tool for a spray robot of the present application. Through the debugging tool for a spray robot of the present application, not only can the debugging tool be quickly installed on the production line to improve the debugging efficiency, but also the spray width of the spray robot's spray gun in various working postures can be effectively measured, thereby effectively ensuring the reliability of the debugging results.

[0041] The technical solution of the present application is described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figures 1 to 6 As shown, this embodiment provides a debugging tool 100 for a spray robot, including a base plate 1 and a debugging component 2, the debugging component 2 includes a connecting member 21, a driving member 22 and a debugging spray plate 23, the two ends of the connecting member 21 are respectively connected to the base plate 1 and the driving member 22, and are installed on the base plate 1, the output end of the driving member 22 extends in a horizontal direction and is connected to the debugging spray plate 23, so as to drive the debugging spray plate 23 to rotate around the output end of the driving member 22.

[0044] Through the above technical solution, on the one hand, the debugging tool 100 for the spraying robot of the present application can be installed and placed at any position of the production line through the base plate 1 quickly and stably, so that the setting of the debugging spray plate 23 can be realized quickly and stably, and the debugging efficiency can be effectively improved. On the other hand, the debugging spray plate 23 set in the present application can rotate around the output end of the driving member 22, so that the debugging spray plate 23 can have a surface of various angles to fit the surface of various angles that the spraying robot needs to spray in the actual spraying work, and the spray width of the spray gun of the spraying robot can be measured separately in various working postures, so that the reliability of the debugging structure can be effectively guaranteed.

[0045] In one embodiment of the present application, Figure 1 and Figure 3 As shown, the base plate 1 of the present application can be formed into a U-shaped structure, and the base plate 1 includes a first plate body 11 and a second plate body 12 that are relatively arranged, and a third plate body 13 connected between the first plate body 11 and the second plate body 12, and the connecting member 21 is connected to the third plate body 13 away from the side of the first plate body 11 and the second plate body 12; wherein the first plate body 11 and the second plate body 12 are used to be clamped by a clamp, or the first plate body 11 and the second plate body 12 are used to move on a track.

[0046] In this way, the third plate body 13 configured in this way can facilitate the stable and reliable installation of the connecting part 21, so that the debugging spray plate 23 can be stably and reliably installed on the production line, thereby facilitating the spray width debugging. At the same time, the first plate body 11 and the second plate body 12 configured in this way can be used as the clamping part of the clamp, and can also be used as a movable basic structure (for example, the first plate body 11 and the second plate body 12 are provided with moving wheels or connected to a moving device), so that it can be adapted to production lines of various sizes and forms, which is beneficial to improving the installation efficiency of the debugging spray plate 23, and then improving the spray width debugging efficiency.

[0047] In one embodiment of the present application, the connector 21 of the present application can be set as a telescopic rod. In this way, the setting height of the debugging spray plate 23 can be adjusted by adjusting the telescopic length of the connector 21, so as to be applicable to various spraying robots (for example, a spraying robot for spraying structures with smaller height space dimensions such as vehicle doors and vehicle chassis, and a spraying robot for spraying structures with larger height space dimensions such as vehicle bodies), thereby effectively improving the versatility of the debugging tool 100 for spraying robots of the present application.

[0048] It is understandable that the telescopic rod of the present application can be electrically controlled, hydraulically or pneumatically driven, or a mechanical telescopic structure, and the present application does not make any specific limitations on this.

[0049] In one embodiment of the present application, Figure 1 , Figure 4 and Figure 5 As shown, the driving member 22 of the present application may include a driving device 221 and a rotating rod 222, wherein the driving device 221 is connected to the rotating rod 222 to drive the rotating rod 222 to rotate, and the debugging spray plate 23 is connected to the rotating rod 222. In this way, by connecting the debugging spray plate 23 to the rotating rod 222, the connection difficulty of the driving member 22 and the debugging spray plate 23 can be effectively reduced.

[0050] In one embodiment of the present application, Figures 4 to 6 As shown, the rotating rod 222 of the present application may include a rod body 2221, a limit block 2222 and a locking block 2223, the limit block 2222 is fixedly arranged on the rod body 2221, the debugging spray plate 23 is sleeved on the rod body 2221, both ends of the rod body 2221 protrude from the debugging spray plate 23, one end of the rod body 2221 is connected to the driving device 221, and the other end of the rod body 2221 is provided with an external thread section, the locking block 2223 is formed into an annular structure, and an internal thread matching the external thread is formed on the inner wall of the locking block 2223; the debugging tool 100 for the spray robot includes a locking state, in which the two ends of the debugging spray plate 23 are respectively against the limit block 2222 and the locking block 2223.

[0051] In this way, through the rotating rod 222 set in this way, not only can the debugging spray plate 23 and the rod body 2221 rotate synchronously to adjust the angle of the debugging spray plate 23, but it is also beneficial to facilitate the disassembly of the debugging spray plate 23, so that the debugging spray plate 23 can be easily installed, disassembled and replaced.

[0052] In one embodiment of the present application, Figure 6 As shown, the locking block 2223 of the present application may include a buffer section 2223a and a locking section 2223b connected to each other, the buffer section 2223a is set as a flexible structure, and the inner wall of the locking section 2223b is provided with an internal thread; in the locked state, the debugging spray plate 23 and the buffer section 2223a abut against each other. In this way, the buffer section 2223a can not only reduce the wear between the locking section 2223b and the debugging spray plate 23, so that the locking block 2223 of the present application can be reused many times, but also help to improve the friction between the locking block 2223 and the debugging spray plate 23, so as to ensure the installation stability of the debugging spray plate 23.

[0053] In one embodiment of the present application, Figure 1 and Figure 4 As shown, the debugging spray plate 23 of the present application can be formed into a square plate structure. In this way, the debugging spray plate 23 of the square plate structure has a large surface area, and can perform multiple spray width adjustments during one debugging process. At the same time, it has a relatively regular structure and can be easily and stably connected to the driving member 22.

[0054] In the actual debugging process, the spray flow debugging of the spray robot is also an important debugging aspect. In the existing debugging process, the spray robot is generally controlled to spray paint liquid into the measuring tool within a few seconds, so as to calculate the spray flow according to the sprayed volume and time, and then the spray flow is debugged according to the calculated spray flow. However, the existing spray flow debugging needs to be tested separately, that is, the spray flow debugging will be carried out after (or before) completing other debugging processes. This is because the existing spray robots are generally set in automatic spray workshops. During the operation of the automatic spray workshop, according to safety regulations, operators can only operate in the external control room and cannot enter the automatic spray workshop. In this way, it is necessary for the operator to enter the automatic spray workshop to install and place the corresponding measuring tools before or after the start of other debugging processes. In other words, the existing spray flow debugging needs to be carried out separately, which is inconvenient, resulting in low debugging efficiency.

[0055] In view of this, in one embodiment of the present application, Figure 1 and Figure 2As shown, the debugging tool 100 for a spraying robot of the present application may further include a measuring cup 3, and the top surface of the base plate 1 is recessed inward to form a placement cavity 14 for placing the measuring cup 3; wherein the placement cavity 14 is formed as a hemispherical structure, and the measuring cup 3 includes a cup body 31 and a cup bottom 32 that are interconnected, and the cup bottom 32 is formed as a hemispherical structure that matches the placement cavity 14, and the cup body 31 is formed as a circular ring structure, and the cup body 31 and the cup bottom 32 together form a holding cavity for holding the paint liquid.

[0056] In this way, the present application provides a placement cavity 14 for placing the measuring cup 3 on the bottom plate 1, so that the spray flow rate can be adjusted while the spray width is being adjusted (or before the spray width is adjusted, or after the spray width is adjusted), which can effectively improve the efficiency of the entire adjustment process. In addition, the placement cavity 14 and the cup bottom 32 provided in this way can make the measuring cup 3 be placed on the bottom plate 1 more stably and reliably, and at the same time facilitate the removal and placement of the measuring cup 3.

[0057] Taking a specific implementation as an example, for example, a certain spray robot needs to test its spray width in horizontal posture, inclined posture and inverted posture, and also needs to test its spray flow in horizontal posture, inclined posture and inverted posture. The spray gun of the spray robot can be adjusted to a horizontal posture first, and at the same time, the debugging spray plate 23 is adjusted to a vertical state. At this time, the debugging of the spray width and spray flow in the horizontal posture can be completed in succession, and then the spray gun of the spray robot can be adjusted to an inclined posture, and at the same time, the debugging spray plate 23 is adjusted to an inclined state. At this time, the debugging of the spray width and spray flow in the inclined posture can be completed in succession. Then, the spray gun of the spray robot can be adjusted to an inverted posture, and at the same time, the debugging spray plate 23 is adjusted to a horizontal state. At this time, the debugging of the spray width and spray flow in the inverted posture can be completed.

[0058] Compared with the existing related technologies, the debugging tool 100 for the spray robot itself can complete the relevant debugging process of the spray width and the spray flow rate more quickly and conveniently, and can more effectively improve the debugging efficiency.

[0059] In one embodiment of the present application, Figure 1 As shown, the placement chamber 14 and the measuring cup 3 of the present application are respectively provided in plurality, and the plurality of placement chambers are arranged at intervals on the bottom plate 1. In this way, multiple spray flow rate adjustments can be performed during one adjustment process (for example, during one adjustment process, the spray flow rate of the spray robot in various working postures can be adjusted), which is convenient for improving the adjustment efficiency.

[0060] Since there are usually multiple spraying robots, it is convenient to spray the parts to be sprayed more quickly and at multiple angles. For example, in the vehicle mid-coating process, there are usually four spraying robots, two of which spray the sides of the vehicle, and the other two spray the engine hood, roof, tailgate, etc.

[0061] In view of this, in one embodiment of the present application, Figure 1 As shown, the debugging assembly 2 of the present application can be set to two, and the two debugging assemblies 2 are arranged at intervals on the bottom plate 1. In this way, the two debugging assemblies 2 set can debug the spraying robots on both sides of the production line at the same time, which can further improve the debugging efficiency.

[0062] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
