One end of the second rotation adjustment member is provided on the second operating table board, and the other end of the second rotation adjustment member is provided on the inner side wall of the cleaning liquid collection tank. The structure is simple, expandable, and easy to clean and disinfect. However, when detecting the color difference of paint spraying samples, the existing method of manually taking a spectrophotometric colorimeter for contact detection is not convenient for detecting a large number of paint spraying samples, with low detection efficiency, and it is not convenient to position the paint spraying samples during detection, reducing the accuracy of paint performance detection.

[0004] Therefore, an operating table for paint performance detection is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an operating table for paint performance detection to solve the problems of inconvenience in detecting the color difference of a large number of paint spraying samples, low detection efficiency, inconvenience in positioning the paint spraying samples during detection, and reduction in the accuracy of paint performance detection.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An operating table for paint performance detection, including a support table, a colorimeter main body, a sample main body, and a support backboard fixedly installed on one side of the top back of the support table. The top of the support backboard is fixedly connected with a top board; Further included are: On one side of the front of the top of the support table, a linear guide rail is fixedly installed. The output end of the linear guide rail is fixedly installed with a moving seat. The top of the moving seat is fixedly connected with a connecting plate. A detection component is arranged at the bottom of the top plate, and a positioning component is arranged at the top of the connecting plate; The positioning component includes a placement box fixedly installed on the connecting plate. On one side of the placement box close to the support back plate, a connecting sleeve is fixedly installed. Inside the connecting sleeve, a third spring is fixedly connected. One side of the third spring is fixedly connected with an arc-shaped convex block; The detection component includes a lifting unit and a docking unit. The color difference meter main body can be lifted up and down through the lifting unit. The docking unit includes a rack installed in a sliding manner and a gear installed in a rotating manner. By the extrusion of the arc-shaped convex block on the rack, the gear is driven to rotate, so as to facilitate the downward pressing and detection of the color difference meter main body through the lifting unit, improving the continuity and efficiency of detection.

[0007] Preferably, the detection component further includes a cross plate and a mounting plate fixedly installed on the top of the support table. The mounting plate is located between the linear guide rail and the support back plate. The rack and the gear are both installed on the outside of the mounting plate. One side of the cross plate is fixedly installed with a moving plate. The top of the mounting plate is fixedly connected with a vertical rod. The mounting plate is slidably connected with the vertical rod. The bottom of the top plate is symmetrically and fixedly connected with positioning rods. The number of positioning rods is not less than two. The cross plate is slidably connected with the positioning rods. The moving plate is located on the side of the cross plate close to the support back plate. A first spring is sleeved on the outside of the vertical rod. An inner groove is opened inside the mounting plate. A cross bar is fixedly connected horizontally inside the inner groove. A sliding block is slidably connected to the outside of the cross bar. The sliding block is fixedly connected with the rack.

[0008] By adopting the above technical solution, the arc-shaped convex block pushes the rack and the sliding block to move. The rack drives the gear to rotate. The gear drives the rotating shaft and the winding sleeve to rotate. The cross plate drives the color difference meter main body to descend, facilitating the color difference meter main body to descend to the maximum distance and contact and detect the top surface of the sample main body.

[0009] Preferably, on the upper part of one side of the front of the mounting plate, a rotating shaft is rotatably connected. The rotating shaft is fixedly connected with the gear. The end of the rotating shaft away from the gear is fixedly connected with a winding sleeve. A pulling rope is wound around the outside of the winding sleeve. The pulling rope passes through the mounting plate and is fixedly connected with the bottom of the moving plate.

[0010] By adopting the above technical solution, the sliding block slides on the cross bar and compresses the second spring. The rack drives the gear to rotate. The gear drives the rotating shaft and the winding sleeve to rotate. The winding sleeve winds up the pulling rope.

[0011] Preferably, both ends of the first spring are fixedly connected to the top of the mounting plate and the bottom of the moving plate respectively. A second spring is sleeved outside the cross bar, and both ends of the second spring are fixedly connected to the sliding block and the inner wall of the inner groove respectively. A side groove is formed in the lower part of one side of the front surface of the mounting plate, and the sliding block is slidably connected to the side groove.

[0012] By adopting the above technical solution, when the arc-shaped convex block is squeezed to the position on the side of the rack away from the mounting plate, the second spring drives the sliding block and the rack to reset, the gear rotates back, and the pulling rope pays out the line.

[0013] Preferably, two fixing plates are symmetrically and fixedly connected to the bottom of the cross plate, and the color difference meter main body is fixedly installed between the two fixing plates by bolts.

[0014] By adopting the above technical solution, it is convenient for the installation, fixation, disassembly and maintenance of the color difference meter main body.

[0015] Preferably, a top groove is further formed in the top of the support platform. A limiting block is fixedly connected to the bottom of the moving seat. The limiting block is located inside the top groove, and the limiting block is slidably connected to the top groove.

[0016] By adopting the above technical solution, the linear guide rail drives the moving seat and the connecting plate to move, and the moving seat drives the limiting block to slide inside the top groove, improving the moving stability.

[0017] Preferably, the placement boxes are evenly arranged at equal distances, there are no less than three placement boxes, the elastic coefficient of the third spring is greater than the elastic coefficients of the first spring and the second spring, and the arc-shaped convex block is slidably connected to the connecting sleeve.

[0018] By adopting the above technical solution, it is convenient to place the sample main body on the top of the placement plate for fixed detection.

[0019] Preferably, a pressing plate is rotatably connected to one side of the top of the placement box away from the support back plate. A lead screw is rotatably connected to one side of the top of the front surface of the connecting plate, and a fixing piece is threadedly connected to the outside of the lead screw.

[0020] By adopting the above technical solution, when the lead screw is rotated, the auxiliary groove limits the fixing piece, so that the rotation of the lead screw will drive the fixing piece and the placement plate to move upward. The placement plate drives the sample main body to rise until the top surface of the sample main body abuts against the pressing plate, thus completing the positioning of the sample main body.

[0021] Preferably, an auxiliary groove is formed in one side of the placement box close to the lead screw. A placement plate is fixedly connected to one side of the fixing piece close to the connecting sleeve, and the placement plate is slidably connected to the placement box.

[0022] By adopting the above technical solution, the top surface heights of the sample main bodies are kept the same, which is convenient for the subsequent descent detection of the color difference meter main body.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: A detection component is provided. The operator places the sample body to be detected inside the placement box and keeps the top surfaces of all sample bodies tightly against the pressing plate for fixation. Connect the color difference meter body to the mobile phone via Bluetooth for easy viewing of the detection data. Then start the linear guide to work. The linear guide drives the moving seat and the connecting plate to move. The moving seat drives the limiting block to slide inside the top groove, and the connecting plate drives multiple placement boxes at the top to move. The placement box drives the connecting sleeve and the arc-shaped convex block to move. When the arc-shaped convex block contacts the left side of the rack, since the spring constant of spring three is greater than that of spring one and spring two, under the same force, spring one and spring two are compressed first. At this time, the arc-shaped convex block pushes the rack and the sliding block to move. The sliding block slides on the cross bar and compresses spring two. The rack drives the gear to rotate, and the gear drives the rotating shaft and the winding sleeve to rotate. The winding sleeve winds up the pulling rope. The pulling rope pulls the moving plate and the cross plate to descend. The moving plate compresses spring one. The cross plate drives the color difference meter body to descend. When the sliding block moves to the rightmost side of the side groove, the rack stops moving, and the color difference meter body descends to the maximum distance and contacts the top surface of the sample body for detection. The detection data is sent to the mobile phone via Bluetooth for easy reading by the operator. Then, the arc-shaped convex block is squeezed by the rack and will slide into the connecting sleeve and compress spring three. The placement box continues to move, so that the detected sample body is removed. When the arc-shaped convex block is squeezed to the position on the side of the rack away from the mounting plate, spring two drives the sliding block and the rack to reset. The gear rotates back, the pulling rope unwinds, and spring one drives the moving plate to reset. The moving plate drives the cross plate and the color difference meter body to move up and reset, facilitating the detection and use of the next sample body, thereby improving the continuity of detection, reducing the operator's hand-held operation, improving the detection efficiency, and solving the problem of inconvenient color difference detection of a large number of paint spraying samples and low detection efficiency; A positioning component is provided. When positioning the sample body, the operator rotates the pressing plate, places the sample body on the top of the placement plate, then rotates the pressing plate back, and then rotates the screw rod. The auxiliary groove limits the fixed piece, so that the rotation of the screw rod will drive the fixed piece to move up. The fixed piece slides in the auxiliary groove and drives the placement plate to move up. The placement plate drives the sample body to rise until the top surface of the sample body tightly abuts against the pressing plate, thus completing the positioning of the sample body and keeping the top surface heights of the sample bodies the same, facilitating the subsequent descent detection of the color difference meter body and improving the stability of detection.

[0028] On the front side of the top of the support table 1, a linear guide rail 4 is fixedly installed. The model of the linear guide rail 4 is a ball guide rail. The output end of the linear guide rail 4 is fixedly installed with a moving seat 10, and the top of the moving seat 10 is fixedly connected to a connecting plate 5.

[0029] At the bottom of the top plate 3, a detection component 6 is provided. The detection component 6 includes a lifting unit and a docking unit. The color difference meter main body 8 can be lifted up and down through the lifting unit. The docking unit includes a slidably installed rack 613 and a rotatably installed gear 615, which facilitates the lifting unit to press down on the color difference meter main body 8 for detection, improving the continuity and efficiency of detection.

[0030] The detection component 6 further includes a cross plate 62 and a mounting plate 65 fixedly installed on the top of the support table 1. The mounting plate 65 is located between the linear guide rail 4 and the support back plate 2. Both the rack 613 and the gear 615 are installed on the outside of the mounting plate 65. On one side of the cross plate 62, a moving plate 64 is fixedly installed. The top of the mounting plate 65 is fixedly connected to a vertical rod 66, and the mounting plate 65 is slidably connected to the vertical rod 66.

[0031] On the bottom of the cross plate 62, two fixing plates 63 are symmetrically and fixedly connected. The color difference meter main body 8 is fixedly installed between the two fixing plates 63 by bolts.

[0032] On the bottom of the top plate 3, positioning rods 61 are symmetrically and fixedly connected. There are no less than two positioning rods 61. The cross plate 62 is slidably connected to the positioning rods 61. The moving plate 64 is located on the side of the cross plate 62 close to the support back plate 2. A first spring 67 is sleeved outside the vertical rod 66. An inner groove 68 is opened inside the mounting plate 65. A cross bar 69 is horizontally and fixedly connected inside the inner groove 68. A sliding block 610 is slidably connected to the outside of the cross bar 69. The sliding block 610 is fixedly connected to the rack 613.

[0033] On the upper part of the front side of the mounting plate 65, a rotating shaft 614 is rotatably connected. The rotating shaft 614 is fixedly connected to the gear 615. The end of the rotating shaft 614 away from the gear 615 is fixedly connected to a winding sleeve 616. A pull rope 617 is wound around the outside of the winding sleeve 616. The pull rope 617 passes through the mounting plate 65 and is fixedly connected to the bottom of the moving plate 64.

[0034] One end of the first spring 67 is fixedly connected to the top of the mounting plate 65 and the other end is fixedly connected to the bottom of the moving plate 64. A second spring 611 is sleeved outside the cross bar 69. Two ends of the second spring 611 are fixedly connected to the sliding block 610 and the inner wall of the inner groove 68 respectively. A side groove 612 is formed in the lower part of the front side of the mounting plate 65. The sliding block 610 is slidably connected to the side groove 612.

[0035] A top groove 11 is further formed in the top of the support platform 1. A limiting block 12 is fixedly connected to the bottom of the moving seat 10. The limiting block 12 is located inside the top groove 11 and is slidably connected to the top groove 11.

[0036] Example 1: As Figures 5-10 shown, the operator places the sample body 9 to be detected inside the placement box 71 and keeps the top surfaces of all the sample bodies 9 tightly pressed against the pressing plate 75 for fixation. Connect the color difference meter body 8 to the mobile phone Bluetooth for easy viewing of the detection data. Then start the linear guide rail 4 to work. The linear guide rail 4 drives the moving seat 10 and the connecting plate 5 to move. The moving seat 10 drives the limiting block 12 to slide inside the top groove 11. The connecting plate 5 drives a plurality of placement boxes 71 on the top to move. The placement box 71 drives the connecting sleeve 72 and the arc-shaped convex block 74 to move. When the arc-shaped convex block 74 contacts the left side of the rack 613, since the elastic coefficient of the third spring 73 is greater than that of the first spring 67 and the second spring 611, under the same force, the first spring 67 and the second spring 611 are compressed first.

[0037] At this time, the arc-shaped convex block 74 pushes the rack 613 and the sliding block 610 to move. The sliding block 610 slides on the cross bar 69 and compresses the second spring 611. The rack 613 drives the gear 615 to rotate. The gear 615 drives the rotating shaft 614 and the winding sleeve 616 to rotate. The winding sleeve 616 winds up the pull rope 617. The pull rope 617 pulls the moving plate 64 and the cross plate 62 to descend. The moving plate 64 compresses the first spring 67. The cross plate 62 drives the color difference meter body 8 to descend. When the sliding block 610 moves to the rightmost side of the side groove 612, the rack 613 stops moving. The color difference meter body 8 descends to the maximum distance and contacts the top surface of the sample body 9 for detection. The detection data is sent to the mobile phone via Bluetooth for easy reading by the operator.

[0038] Subsequently, the arc-shaped convex block 74 is squeezed by the rack 613, slides into the connecting sleeve 72 and compresses the third spring 73. The placement box 71 continues to move, causing the detected sample body 9 to be removed. When the arc-shaped convex block 74 is squeezed to the side of the rack 613 away from the mounting plate 65, the second spring 611 drives the sliding block 610 and the rack 613 to reset. The gear 615 rotates, the pulling rope 617 pays out the line, and the first spring 67 drives the moving plate 64 to reset. The moving plate 64 drives the cross plate 62 and the color difference meter body 8 to move upward and reset, facilitating the detection and use of the next sample body 9, thereby improving the continuity of detection, reducing the manual operation of the operator, improving the detection efficiency, and solving the problem of inconvenient color difference detection for a large number of paint spraying samples and low detection efficiency.

[0039] A positioning component 7 is arranged on the top of the connecting plate 5. The positioning component 7 includes a placement box 71 fixedly installed on the connecting plate 5. A connecting sleeve 72 is fixedly installed on one side of the placement box 71 close to the support back plate 2. A third spring 73 is fixedly connected inside the connecting sleeve 72. One side of the third spring 73 is fixedly connected with an arc-shaped convex block 74.

[0040] The placement boxes 71 are evenly arranged at equal distances, and there are no less than three placement boxes 71. The elastic coefficient of the third spring 73 is greater than the elastic coefficients of the first spring 67 and the second spring 611. The arc-shaped convex block 74 is slidably connected with the connecting sleeve 72.

[0041] One side of the top of the placement box 71 away from the support back plate 2 is rotatably connected with a pressing plate 75. One side of the front of the top of the connecting plate 5 is rotatably connected with a lead screw 76. A fixing piece 77 is threadedly connected to the outside of the lead screw 76.

[0042] An auxiliary groove 78 is opened on one side of the placement box 71 close to the lead screw 76. One side of the fixing piece 77 close to the connecting sleeve 72 is fixedly connected with a placement plate 79. The placement plate 79 is slidably connected with the placement box 71.

[0043] Embodiment 2: As Figures 3-4 and Figures 11-13 shown, when positioning the sample body 9, the operator rotates the pressing plate 75, places the sample body 9 on the top of the placement plate 79, then rotates the pressing plate 75 back, and then rotates the lead screw 76. The auxiliary groove 78 limits the fixing piece 77, so that the rotation of the lead screw 76 will drive the fixing piece 77 to move upward. The fixing piece 77 slides in the auxiliary groove 78 and drives the placement plate 79 to move upward. The placement plate 79 drives the sample body 9 to rise until the top surface of the sample body 9 abuts against the pressing plate 75, thereby completing the positioning of the sample body 9 and keeping the top surface height of the sample body 9 the same, facilitating the subsequent downward detection of the color difference meter body 8 and improving the stability of detection.

[0044] Working principle: When using this device, first, as Figures 1-13As shown, the operator places the sample body 9 on the top of the placement plate 79, then rotates the pressing plate 75. The placement plate 79 drives the sample body 9 to rise until the top surface of the sample body 9 abuts against the pressing plate 75, completing the positioning of the sample body 9. Then, the linear guide rail 4 is started to work. The linear guide rail 4 drives the moving seat 10 and the connecting plate 5 to move. The connecting plate 5 drives a plurality of placement boxes 71 on the top to move. The arc-shaped convex block 74 pushes the rack 613 and the sliding block 610 to move. The cross plate 62 drives the color difference meter body 8 to descend. When the sliding block 610 moves to the rightmost side of the side groove 612, the rack 613 stops moving. The color difference meter body 8 descends to the maximum distance and contacts the top surface of the sample body 9 for detection. Then, the arc-shaped convex block 74 is squeezed by the rack 613 and will slide into the connecting sleeve 72 and compress the spring three 73. The placement box 71 continues to move, removing the detected sample body 9. When the arc-shaped convex block 74 is squeezed to the position on the side of the rack 613 away from the mounting plate 65, the spring two 611 drives the sliding block 610 and the rack 613 to reset. The gear 615 rotates, the pulling rope 617 pays out the line, and the spring one 67 drives the moving plate 64 to reset. The moving plate 64 drives the cross plate 62 and the color difference meter body 8 to move up and reset, facilitating the detection and use of the next sample body 9.
