Description

Technical Field

[0001] The utility model relates to the technical field of spraying detection equipment, in particular to a performance testing device for a spraying robot. Background Art

[0002] Paint spraying is a coating method that disperses the paint into a mist and sprays it onto the surface of an object. Spraying can form a uniform, smooth, and dense coating on the surface of various materials, thereby protecting, decorating, and providing special functions (such as insulation, waterproofing, and rust prevention) to the object. Robotic spraying has higher precision, better repeatability, and higher efficiency, especially in mass production. Testing the spraying effect is an important part of ensuring the quality and performance of the coating. At present, when performing performance testing on spraying, high-cost industrial camera modules are used; or only a single aspect is tested each time, and the overall testing time is longer.

[0003] The Chinese utility model patent with the name of "A spray coating detection device" and the publication number CN218066398U that has been published includes a positioning component and a fixing component. The positioning component includes: an elastic band, which is put on the outside of the spray object; a buckle, which is arranged on the elastic band for connection and fixation; a fixing plate, which is put on several elastic bands and is equipped with an electric buffer rod; a fixing pad, which is fixed on the movable end of the electric buffer rod; a fixing instrument, which is fixed on the inside of the fixing plate for detecting the coating. The fixing component is arranged on the fixing plate, including a connecting rod, which is inserted horizontally into the fixing plate. Through the positioning component, the device can uniformly fix each detection instrument on the spray object, without the need to hold the detection instrument in turn for detection. However, if it is fixed on the spray object and the spray object is rough and uneven, it will still affect the detection accuracy of each detection instrument. Utility Model Content

[0026] Example

[0027] Please refer to Figure 1-Figure 5 The utility model provides a spraying robot performance testing device, including a spraying structure and a detection component.

[0028] Furthermore, the spraying structure includes a base plate 1, a spraying plate 2, a marking line 3, a support seat 4, and a guide plate 5. The top surface of the base plate 1 is provided with a square groove, one side of the groove is open, and the groove is cooperated with the spraying plate 2 to be installed. The spraying plate 2 can slide into the groove from the opening of the groove of the base plate 1 for quick replacement. The top surfaces of the base plate 1 and the spraying plate 2 are located in the same horizontal plane without any height difference. At least two circles of marking lines 3 are provided in the center of the spraying plate 2. The marking lines 3 are waist-shaped colored marking lines. The thickness of the marking lines 3 can be ignored, and the spacing between two adjacent marking lines 3 is the same. The guide plate 5 is located directly above the marking lines 3 and is supported by the support seat 4 fixed on the base plate 1. The guide plate 5 is at a certain height from the marking lines 3, which is the normal spraying distance of the spraying robot during the spraying operation. There is a guide groove inside the guide plate 5 to guide the movement of the robot.

[0029] During spraying, the robot spray nozzle slides in the guide groove of the guide plate 5 to spray the top surface of the spray plate 2. The paint diffuses radially after being sprayed out, and the edge of the paint diffuses to different positions of the marking line 3. By observing whether the radiation range of the sprayed paint is uniform, the uniformity of the spray diffusion range is detected.

[0030] Furthermore, a spray robot performance testing device also includes a driving structure 6, in which a connecting column 605 is provided, and the connecting column 605 is fixedly connected to the detection component. The driving structure 6 drives the detection component to move, and the moving path is perpendicular to the movement path of the robot in the guide groove of the guide plate 5.

[0031] Furthermore, the detection component includes a mounting plate 7 and a blade scraper 701.

[0032] Specifically, the left and right sides of the mounting plate 7 are fixedly connected with connecting columns 605, and at least two slide grooves are arranged inside the mounting plate 7, and the shape of the slide groove matches the shape of the spray plate 2 of the mounting plate 70. The blade scraper 701 is slidably installed in the slide groove in the mounting plate 7, and at least two blade scrapers 701 are arranged on the mounting plate 7. The blade scraper 701 slides to the end of the slide groove, and the end of the slide groove has a positioning hole to prevent the blade scraper 701 from continuing to move after sliding into place. The bottom end of the blade scraper 701 is blade-shaped, and the bottom end is in sliding contact with the top surface of the spray plate 2. There is friction between the bottom end of the blade scraper 701 and the top surface of the spray plate 2, which scrapes off the paint layer on the top surface of the spray plate 2. The mounting plate 7 is at the projection position of the top surface of the base plate 1, and the base plate 1 is provided with a margin groove, so that when the blade scraper 701 on the mounting plate 7 is installed or replaced, it will not contact with the top surface of the base plate 1 to generate friction, thereby affecting the removal.

[0033] During the inspection, the mounting plate 7 is driven by the driving structure 6 to slide on the top surface of the spray plate 2. The friction force generated by the blade-shaped bottom end of the blade scraper 701 sliding on the top surface of the spray plate 2 scrapes off the paint layer sprayed on the spray plate 2. After the blade scraper 701 moves over the top surface of the spray plate 2, the exposure degree of the upper surface of the spray plate 2 is observed to detect the uniformity of the spraying; if the surface distribution of the exposed spray plate 2 is relatively uniform, the inspection is qualified; if the surface distribution of the exposed spray plate 2 is relatively random and uneven, the inspection is unqualified.

[0034] Furthermore, the detection component also includes a particle size detection structure 8 , and the particle size detection structure 8 includes a cavity plate 801 , an ink storage box 802 , a marking head 803 , and an ink absorbing plate 804 .

[0035] Specifically, the left and right sides of the cavity plate 801 are fixedly connected with connecting columns 605, the top of the cavity plate 801 is threadedly installed with an ink cartridge 802, the ink cartridge 802 stores ink, the cavity plate 801 is provided with a cavity and an ink channel, the ink cartridge 802 is connected with the cavity, and the ink enters the ink channel from the ink cartridge 802 through the cavity; the bottom of the cavity plate 801 is fixedly provided with a marking head 803, at least two marking heads 803 are provided, and are evenly arranged along the movement direction of the robot in the guide groove of the guide plate 5, the marking head 803 is connected with the ink channel of the cavity plate 801, and the marking head 803 is connected with the ink channel of the cavity plate 801, and the marking head 803 is connected with the ink channel of the cavity plate 801. There is an ink outlet at the bottom of the head 803. When the marking head 803 moves, the ink flows out from the ink outlet to draw an ink trajectory line on the top surface of the spray plate 2. The particle size detection structure 8 is at the projection position of the top surface of the bottom plate 1. The bottom plate 1 is provided with an ink collecting groove to collect the ink dripping from the marking head 803. An ink absorbing plate 804 is fixedly installed in the ink collecting groove near the spray structure. There are fine hairs on the ink absorbing plate 804. When the particle size detection structure 8 moves to perform the detection function, the ink outlet at the bottom of the marking head 803 passes through the fine hairs of the ink absorbing plate 804 to prevent the accumulated ink at the ink outlet of the marking head 803 from dripping onto the top surface of the spray plate 2 in a spherical form when moving. (The ink should drip onto the spray plate in a linear form)

[0036] During the inspection, the particle size detection structure 8 is driven by the driving structure 6 to slide on the top surface of the spray plate 2 and slide into the spray structure. The ink flows out from the bottom end of the marking head 803 and displays the movement trajectory of the marking head 803 on the top surface of the spray plate 2. The moving trajectory of the marking head 803 is observed to see whether it touches the large particles of paint agglomerates produced by spraying. The particle size of the spray material is detected by the partially bent trajectory at the ink outlet of the marking head 803 due to the obstruction of the agglomerates. If the particle size during spraying is qualified, the trajectory traces drawn by the moving marking head 803 will not show the phenomenon of bent line segments.

[0037] Furthermore, the detection component also includes a thickness detection structure 9, and the thickness detection structure 9 includes a slide plate 901, a slide plate 902, a thickness measuring block 903, and an elastic telescopic structure.

[0038] Specifically, two slide plates 901 are provided, which are symmetrically distributed on the left and right. The tops of the two slide plates 901 are fixed together by a connecting plate, and the symmetrically distributed outer wall surfaces are fixedly connected with connecting columns 605. The inner walls of the slide plates 901 are provided with slide grooves, and the slide plate 902 slides in the slide grooves of the two slide plates 901. The sliding path is perpendicular to the movement path of the robot in the guide groove of the guide plate 5, and it will slide in the direction away from the spraying structure during detection. A thickness measuring block 903 is fixedly installed at the bottom of the slide plate 902. The bottom surface of the thickness measuring block 903 is spaced from the top surface of the bottom plate 1 by a fixed height, and the height is the height distance of the qualified spraying material layer; an elastic telescopic structure is provided between an inner side end of the slide groove of the slide plate 901 away from the spraying structure and the slide plate 902;

[0039] When the thickness detection structure 9 slides above the spray plate 2 driven by the driving structure 6, if the sprayed paint layer is within the qualified thickness, the thickness measuring block 903 will not contact the paint layer on the top surface of the spray plate 2, and will not be elastically expanded or contracted due to its resistance, and an alarm signal will be issued through the elastic expansion structure; if the sprayed paint layer exceeds the qualified thickness or the thickness of each part is inconsistent, the thickness measuring block 903 will contact the excess end of the paint layer on the top surface of the spray plate 2, and will be elastically expanded or contracted due to its resistance. The expansion amount has a expansion range. If the expansion amount is small, it means that the excess thickness is within the qualified range, and the elastic expansion structure still will not issue an alarm signal. If the expansion amount is large, it means that the excess thickness exceeds the specified qualified range, and the elastic expansion structure will issue an alarm signal.

[0040] Furthermore, the elastic telescopic structure includes a spring 904 , a first contact column 905 , a second contact column 906 , and a signal light 907 .

[0041] Specifically, a second contact post 906 is installed on the inner wall of the slide groove of the slide groove plate 901, and a first contact post 905 is fixedly installed on one end face of the slide plate 902 close to the second contact post 906. The first contact post 905 is coaxial with the second contact post 906, and a spring 904 is provided on its outer sleeve. The two ends of the spring 904 are respectively fixed on the inner wall of the slide groove of the slide groove plate 901 and the end face of the second contact post 906. When the slide plate 902 slides in the slide groove of the slide groove plate 901, it will be subjected to the elastic force applied by the spring 904. The signal lamp 907 is fixedly installed on the outside of the slide groove plate 901, and is connected to the second contact post 906 circuit. There is an electrical signal inside the first contact post 905.

[0042] During the detection, when the slide plate 902 slides, the spring 904 is forced to expand and contract, and the first contact column 905 and the second contact column 906 are relatively close. The two distance ranges from close to contact are the expansion and contraction range of the elastic expansion and contraction structure. When the first contact column 905 is close to the second contact column 906 but not in contact, a closed circuit is not formed, the thickness test is qualified, and the elastic expansion and contraction structure does not generate an alarm signal. When the first contact column 905 contacts the second contact column 906, a closed circuit is formed, the thickness test fails, the electrical signal of the first contact column 905 is transmitted to the circuit of the second contact column 906, the signal light 907 receives the electrical signal and emits an alarm buzzer, and the elastic expansion and contraction structure generates an alarm signal.

[0043] The first contact post 905 and the second contact post 906 are made of metal. The second contact post 906 is connected to the signal light 907. The first contact post 905 is connected to a battery. When the first contact post 905 and the second contact post 906 are in contact, a closed loop is formed so that the signal light 907 works to alarm.

[0044] In some embodiments, a spray robot performance testing device also includes a drive structure 6, wherein the drive structure 6 includes a motor 601, a threaded shaft 602, a threaded block 603, a support plate 604, a connecting column 605, a support block 606, and a linear slide rail 607.

[0045] Furthermore, a motor 601 is fixedly arranged on the left end of the base plate 1, and a threaded shaft 602 is connected to the driving shaft of the motor 601 and rotates coaxially. A threaded block 603 is fixedly installed on the base plate 1, and both ends of the threaded shaft 602 are supported to ensure its rotation. A support plate 604 is coaxially arranged on the threaded shaft 602, and the threaded shaft 602 and the support plate 604 are matched by a threaded connection. The support plate 604 is fixedly connected to one end of a connecting column 605 on the inner side, and the connecting column 605 is connected to fix the detection component and connects the various structures in the detection component to move together in series. The other end of the connecting column 605 is fixedly connected to the inner side of the support block 606. The support block 606 is located at the right end of the base plate 1, and a linear slide rail 607 is fixedly installed on the right end of the base plate 1. The mounting plate 7 of the drive structure 6 thickness detection structure 9 consists of a rail and a slider. The slider slides freely on the rail, and the sliding direction is consistent with the movement direction of the drive structure 6. The bottom of the support block 606 is installed on the slider of the linear slide rail 607.

[0046] When conducting inspection, the motor 601 is started, and the threaded shaft 602 drives the support plate 604 to move toward the spray structure through the threaded transmission, and drives the inspection component to move together through the connecting column 605. The other end of the connecting column 605 is assisted by the linear slide rail 607 for support and sliding, so that the inspection component can perform spray performance inspection on the spray surface on the spray structure.
