Description

Technical Field

[0001] The present invention relates to the technical field of colorimeters, and particularly to a colorimeter for detecting the printing of automobile interiors. Background Art

[0002] After the printing of automobile interiors, it is necessary to detect the color difference of the printed finished automobile interiors to determine whether the required quality is achieved. A colorimeter can be used to measure and display the color difference between the sample and the sample to be measured. Existing colorimeters are generally for handheld detection or sliding detection driven by equipment. However, due to the certain bending curvature of automobile interiors and their surfaces not being very flat, such as the panel of an automobile dashboard, when the colorimeter detects the printing quality, it cannot fit well with the interior panel for contact detection, reducing the detection quality and efficiency.

[0003] For example, a colorimeter for printing detection with the publication number CN210221294U includes a housing. The middle of the bottom end of the housing is fixedly connected with a detection disk. The middle of the housing is detachably connected with a battery box cover. A sliding mechanism is provided at the bottom end of the housing. The sliding mechanism includes a plurality of sliding columns. The sliding columns are arranged around the detection disk at the bottom end of the housing. A pulley is provided at the bottom end of the sliding column. A positioning ring is provided on the side of the sliding column away from the pulley. The positioning ring is located inside the housing. A return spring is symmetrically distributed at the top end of the positioning ring. Through the setting of the sliding mechanism, the practicability of the colorimeter is increased. Through the combined use of the sliding mechanism, when the colorimeter is used for detection, it can slide through the sliding columns at the bottom end, making the use of the colorimeter more convenient. At the same time, the sliding columns can be retracted into the inside of the housing without affecting the normal use of the colorimeter, reducing the situation where the detection disk is damaged. However, handheld detection is greatly affected by individual differences of operators. And when dealing with automobile interiors with curved surfaces, it is not convenient for the colorimeter to fit well with the interior panel for contact detection, reducing the detection quality and efficiency. Moreover, if there is dust and debris adhered to the surface of the interior panel, it will also affect the color difference detection.

[0004] Therefore, a colorimeter for detecting the printing of automobile interiors is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a colorimeter for detecting the printing of automobile interiors to solve the problem that when dealing with automobile interiors with curved surfaces, it is not convenient for the colorimeter to fit well with the interior panel for contact detection, reducing the detection quality and efficiency.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A colorimeter for detecting the printing of automobile interiors includes an operation tabletop, an automobile interior main body, a colorimeter main body, and side frames symmetrically and fixedly connected to both sides of the top of the operation tabletop. Electric push rods are symmetrically and fixedly installed in the middle of the top of the side frames.

[0007] It further includes:

[0008] A side block is fixedly connected to the sleeve part of the electric push rod, and the same cross plate is fixedly connected between the two side blocks. A detection component is arranged below the cross plate, and a pressing component is arranged inside the side frame. A detection end is fixedly installed at the bottom end of the color difference meter main body;

[0009] The detection component includes symmetrically arranged fixing plates. A linear guide rail is fixedly installed between the two fixing plates. The output end of the linear guide rail is fixedly installed with a moving seat. A hydraulic rod is fixedly installed at the bottom of the moving seat. The telescopic end of the hydraulic rod is fixedly connected with a moving plate, and a vertical plate is fixedly connected to one side of the moving plate;

[0010] A lower groove and an upper groove are formed inside the vertical plate. A vertical rod is slidably installed inside the vertical plate. The bottom end of the vertical rod is fixedly connected with a slider. A first spring is sleeved on the outer side of the vertical rod. One end of the slider is fixedly connected with a left clamping block, and a right clamping block is rotatably connected to the side of the left clamping block close to the slider;

[0011] A connecting plate is fixedly connected to the side of the vertical plate away from the moving seat. A positioning plate is slidably installed at the bottom of the connecting plate. One end of the positioning plate is fixedly connected with a second spring. The other end of the positioning plate is fixedly connected with a cross bar. The cross bar is slidably connected with the vertical plate, and the bottom of the cross bar away from the connecting plate is inclined.

[0012] Preferably, the telescopic end of the electric push rod is fixedly connected with the side frame. There are not less than two electric push rods. The number of side blocks is the same as that of the electric push rods. The side blocks are fixedly connected with the cross plate. The vertical plate is in contact with the moving seat. A cleaning ring is fixedly installed at the bottom of the color difference meter main body.

[0013] By adopting the above technical solution, when the moving seat moves linearly, it will drive the vertical plate to move. The cleaning ring first wipes and cleans the detection position of the car interior main body. At the same time, when the arc becomes convex, the positioning plate presses and fixes the color difference meter main body.

[0014] Preferably, the lower groove penetrates through one side of the front surface of the vertical plate. The upper groove is located above the lower groove. The first spring is located inside the lower groove. The top end of the first spring is fixedly connected with the inner top surface of the lower groove. The bottom end of the first spring is fixedly connected with the top of the slider.

[0015] By adopting the above technical solution, when the arc becomes convex, the detection end and the color difference meter main body will be forced to move upward. The color difference meter main body drives the slider to move upward through the left clamping block. The slider compresses the first spring, so that the color difference meter main body and the detection end always press and detect the surface of the car interior main body.

[0016] Preferably, the left clamping block is located outside the vertical plate, a bolt is installed at the end of the right clamping block, and the right clamping block can be fixedly connected to the left clamping block through the bolt.

[0017] By adopting the above technical solution, the color difference meter main body is installed between the left clamping block and the right clamping block and is locked and fixed by bolts.

[0018] Preferably, a fixing strip is fixedly connected to one side of the bottom of the connecting plate. The side of the second spring away from the positioning plate is fixedly connected to the fixing strip. The positioning plate is located outside the vertical plate. The top of the positioning plate is in contact with the bottom of the connecting plate. The positioning plate is located between the color difference meter main body and the vertical plate.

[0019] By adopting the above technical solution, when the slider drives the vertical rod to move upward, the vertical rod presses the inclined surface of the cross rod, the cross rod drives the positioning plate to move, the positioning plate cooperates with the fixing strip to compress the second spring, and the positioning plate presses and fixes the color difference meter main body.

[0020] Preferably, the pressing assembly includes symmetrically arranged screw rod parts. The two screw rod parts are respectively located on the far sides of the two side frames. The bottom end of the screw rod part is rotatably connected to the operation table surface. A cross bar is threadedly connected to the outside of the screw rod part. A double-headed screw rod is horizontally rotatably connected inside the cross bar.

[0021] By adopting the above technical solution, the double-headed screw rod fits against the inner wall of the side frame and does not affect the up and down adjustment.

[0022] Preferably, one end of the double-headed screw rod fits against the back of the inner side wall of the side frame. A vertical groove is opened on one side of the front of the side frame. The double-headed screw rod is slidably connected to the vertical groove. Mounting blocks are symmetrically threadedly connected to the outside of the double-headed screw rod.

[0023] By adopting the above technical solution, the rotation of the double-headed screw rod makes the front and rear two mounting blocks approach each other longitudinally. The mounting blocks on both sides move synchronously. The two mounting blocks on the transverse direction drive the inner pressing plate to move, so as to realize the adjustment of the mutual approach of the two pressing plates, which is convenient for adapting to the pressing of the front and rear positions of the automotive interior main body.

[0024] Preferably, a pressing plate is fixedly connected between the two mounting blocks on the transverse direction. A pressing rod part is fixedly connected to the middle of the bottom of the pressing plate. Side plates are symmetrically fixedly connected to the bottom of the pressing plate.

[0025] By adopting the above technical solution, the cross bar drives the double-headed screw rod, the mounting block and the pressing plate to move downward. The downward movement of the pressing plate makes the pressure roller contact the automotive interior main body first.

[0026] Preferably, a fixing rod is fixedly connected between the adjacent side plates. Rotating sleeves are symmetrically and rotatably installed inside the fixing rod. A strip plate is fixedly connected to the bottom of the rotating sleeve. A pressing roller is rotatably installed at the bottom end of the strip plate. An inner strip is fixedly connected to the middle of the strip plate. A third spring is fixedly connected between two adjacent inner strips.

[0027] By adopting the above technical solution, when the pressing rod part presses on the automotive interior main body, the elastic force of the third spring makes the strip plate and the pressing roller also tightly press on the surface of the automotive interior main body, thereby realizing the stable positioning of the automotive interior main body.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: A detection component is provided. When the operator starts the electric push rod, the linear guide rail and the hydraulic rod, the electric push rod synchronously drives the side block and the cross plate to rise and fall, thereby initially adjusting the position of the color difference meter main body. The hydraulic rod drives the moving plate and the vertical plate to rise and fall for adjustment, facilitating the fine adjustment of the height of the color difference meter main body; When the moving seat moves linearly, it will drive the vertical plate to move. The cleaning ring first wipes and cleans the detection position of the automotive interior main body. At the same time, when the arc becomes convex, the positioning plate tightly presses and fixes the color difference meter main body, thereby reducing the displacement of the color difference meter main body during detection and improving the detection accuracy of the color difference meter main body;

[0029] A detection component is provided. The main body of the color difference meter is installed between the left clamping block and the right clamping block and is locked and fixed by bolts. The operator first places the printed automotive interior main body on the top of the operating table surface so that the detection position is flush with the main body of the color difference meter. The automotive interior main body is clamped and fixed by the pressing component. Then, the electric push rod, linear guide rail, and hydraulic rod are started. The electric push rod synchronously drives the side block and the cross plate to lift, thereby initially adjusting the position of the main body of the color difference meter. The linear guide rail drives the moving seat to adjust the horizontal position, facilitating the moving detection of the color difference by the main body of the color difference meter. Moreover, the hydraulic rod drives the moving plate and the vertical plate to lift and adjust, facilitating the fine adjustment of the height of the main body of the color difference meter. Then, when detecting the automotive interior main body with a surface arc, when the moving seat moves linearly, it will drive the vertical plate to move. The vertical plate drives the left clamping block and the main body of the color difference meter to move through the slider, so that the detection end contacts the automotive interior main body. The main body of the color difference meter drives the cleaning ring to move, facilitating the cleaning ring to first wipe and clean the detection position of the automotive interior main body, reducing the influence of dust on the surface of the automotive interior main body. At the same time, when the arc becomes convex, the detection end and the main body of the color difference meter will be forced to move upward. The main body of the color difference meter drives the slider to move upward through the left clamping block. The slider compresses the first spring. The elastic force of the first spring reacts on the slider, so that the main body of the color difference meter and the detection end always tightly press the surface of the automotive interior main body for detection. Moreover, the slider will drive the vertical rod to move upward. The vertical rod presses the inclined surface of the cross bar, so that the cross bar slides outwards. The cross bar drives the positioning plate to move. The positioning plate cooperates with the fixed strip to compress the second spring, and the positioning plate tightly presses and fixes the main body of the color difference meter, thereby reducing the displacement of the main body of the color difference meter during detection, improving the detection accuracy of the main body of the color difference meter, and being more suitable for detecting the automotive interior main body with a surface arc, solving the problem that when dealing with the automotive interior with a curved surface, the color difference meter is not convenient to fit and contact with the interior panel well, reducing the detection quality and detection efficiency.

[0030] A pressing component is provided. The operator first rotates the double-headed lead screws on both sides. The double-headed lead screws are in contact with the inner wall of the side frame and do not affect the up and down adjustment. When the double-headed lead screws rotate, the front and rear two mounting blocks move longitudinally closer to each other. The two mounting blocks on both sides move synchronously. The two transverse mounting blocks drive the inner pressing plate to move, thereby realizing the adjustment of the two pressing plates approaching each other, facilitating the pressing of the front and rear positions of the automotive interior main body. After adjustment, the operator loosens the double-headed lead screws and then rotates the two screw parts. When the screw parts rotate, the cross bar moves downward. The double-headed lead screws slide inside the vertical slots. The cross bar drives the double-headed lead screws, mounting blocks, and pressing plates to move downward. When the pressing plate moves downward, the pressure roller first contacts the automotive interior main body. The pressure roller drives the strip board to tilt and deflect. The strip board drives the rotating sleeve to rotate on the outside of the fixed rod, realizing the separation of the two strip boards in a V shape. The strip board drives the inner strip to move. The two inner strips stretch the third spring. Until the pressing rod part presses on the automotive interior main body, the elastic force of the third spring makes the strip board and the pressure roller also tightly press the surface of the automotive interior main body, thereby realizing the stable positioning of the automotive interior main body and facilitating subsequent color difference detection.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1 - 12 , the present invention provides a technical solution: a color difference meter for detecting automobile interior printing, including an operating tabletop 1, an automobile interior main body 8, a color difference meter main body 9, and side frames 2 symmetrically and fixedly connected to both sides of the top of the operating tabletop 1. Electric push rods 3 are symmetrically and fixedly installed in the middle of the top of the side frames 2.

[0047] A detection component 6 is arranged below the cross plate 5. The detection component 6 includes symmetrically arranged fixed plates 61. A linear guide rail 62 is fixedly installed between the two fixed plates 61. The output end of the linear guide rail 62 is fixedly installed with a moving seat 63. A hydraulic rod 64 is fixedly installed at the bottom of the moving seat 63. The telescopic end of the hydraulic rod 64 is fixedly connected with a moving plate 65. One side of the moving plate 65 is fixedly connected with a vertical plate 66.

[0048] The interior of the vertical plate 66 is provided with a lower groove 67 and an upper groove 68. A vertical rod 69 is slidably installed inside the vertical plate 66. The bottom end of the vertical rod 69 is fixedly connected with a slider 610. A first spring 611 is sleeved outside the vertical rod 69. One end of the slider 610 is fixedly connected with a left clamping block 612. A right clamping block 613 is rotatably connected to the side of the left clamping block 612 close to the slider 610.

[0049] The lower groove 67 penetrates through one side of the front surface of the vertical plate 66. The upper groove 68 is located above the lower groove 67. The first spring 611 is located inside the lower groove 67. The top end of the first spring 611 is fixedly connected with the inner top surface of the lower groove 67. The bottom end of the first spring 611 is fixedly connected with the top of the slider 610.

[0050] The left clamping block 612 is located outside the vertical plate 66. A bolt is installed at the end of the right clamping block 613. The right clamping block 613 can be fixedly connected with the left clamping block 612 through the bolt.

[0051] One side of the vertical plate 66 away from the moving seat 63 is fixedly connected with a connecting plate 614. A positioning plate 617 is slidably installed at the bottom of the connecting plate 614. One end of the positioning plate 617 is fixedly connected with a second spring 616. The other end of the positioning plate 617 is fixedly connected with a cross bar 618. The cross bar 618 is slidably connected with the vertical plate 66. The bottom of the side of the cross bar 618 away from the connecting plate 614 is inclined.

[0052] One side at the bottom of the connecting plate 614 is fixedly connected with a fixing strip 615. The side of the second spring 616 away from the positioning plate 617 is fixedly connected with the fixing strip 615. The positioning plate 617 is located outside the vertical plate 66. The top of the positioning plate 617 is in contact with the bottom of the connecting plate 614. The positioning plate 617 is located between the color difference meter body 9 and the vertical plate 66.

[0053] The telescopic end of the electric push rod 3 is fixedly connected with the side frame 2. There are no less than two electric push rods 3. The number of side blocks 4 is the same as that of the electric push rods 3. The side blocks 4 are fixedly connected with the cross plate 5. The vertical plate 66 is in contact with the moving seat 63. A cleaning ring 619 is fixedly installed at the bottom of the color difference meter body 9.

[0054] Example 1: As Figures 1 - 9As shown, the color difference meter main body 9 is installed between the left clamping block 612 and the right clamping block 613 and is fixed by bolts. The operator first places the printed automotive interior main body 8 on the top of the operation table 1 so that the detection position is flush with the color difference meter main body 9. The automotive interior main body 8 is fixed by pressing through the pressing assembly 7. Then, the electric push rod 3, the linear guide rail 62 and the hydraulic rod 64 are started. The electric push rod 3 synchronously drives the side block 4 and the cross plate 5 to move up and down, thereby initially adjusting the position of the color difference meter main body 9. The linear guide rail 62 drives the moving seat 63 to adjust the horizontal position, which is convenient for the color difference meter main body 9 to move for color difference detection. And the hydraulic rod 64 drives the moving plate 65 and the vertical plate 66 to move up and down for fine adjustment of the height of the color difference meter main body 9.

[0055] Then, the automotive interior main body 8 with a surface curvature is detected. When the moving seat 63 moves linearly, it will drive the vertical plate 66 to move. The vertical plate 66 drives the left clamping block 612 and the color difference meter main body 9 to move through the slider 610, so that the detection end 91 contacts the automotive interior main body 8. The color difference meter main body 9 drives the cleaning ring 619 to move, which is convenient for the cleaning ring 619 to first wipe and clean the detection position of the automotive interior main body 8, reducing the influence of dust on the surface of the automotive interior main body 8. At the same time, when the curvature becomes convex, the detection end 91 and the color difference meter main body 9 will be forced to move up. The color difference meter main body 9 drives the slider 610 to move up through the left clamping block 612, and the slider 610 compresses the first spring 611. The elastic force of the first spring 611 acts on the slider 610 in the opposite direction, so that the color difference meter main body 9 and the detection end 91 always press against the surface of the automotive interior main body 8 for detection.

[0056] And the slider 610 will drive the vertical rod 69 to move up. The vertical rod 69 squeezes the inclined surface of the cross bar 618, so that the cross bar 618 slides outwards. The cross bar 618 drives the positioning plate 617 to move. The positioning plate 617 cooperates with the fixed strip 615 to compress the second spring 616, and the positioning plate 617 presses and fixes the color difference meter main body 9, thereby reducing the displacement of the color difference meter main body 9 during detection, improving the detection accuracy of the color difference meter main body 9, and being more suitable for detecting the automotive interior main body 8 with a surface curvature, solving the problem that when dealing with automotive interiors with a curved surface, the color difference meter is not convenient to fit and contact the interior panel well, reducing the detection quality and detection efficiency.

[0057] A pressing assembly 7 is arranged inside the side frame 2. The pressing assembly 7 includes symmetrically arranged lead screw parts 71. The two lead screw parts 71 are respectively located on the two sides of the two side frames 2 away from each other. The bottom end of the lead screw part 71 is rotatably connected to the operation table 1. A cross bar 72 is threadedly connected to the outside of the lead screw part 71. A double-headed lead screw 73 is horizontally rotatably connected inside the cross bar 72.

[0058] One end of the double-headed lead screw 73 is in contact with the back surface of the inner side wall of the side frame 2. A vertical groove 74 is provided on one side of the front surface of the side frame 2. The double-headed lead screw 73 is slidably connected to the vertical groove 74. Mounting blocks 75 are symmetrically threadedly connected to the outside of the double-headed lead screw 73.

[0059] A pressing plate 76 is fixedly connected between the two horizontally arranged mounting blocks 75. A pressing rod portion 77 is fixedly connected to the middle of the bottom of the pressing plate 76. Side plates 78 are symmetrically fixedly connected to the bottom of the pressing plate 76.

[0060] A fixing rod 79 is fixedly connected between adjacent side plates 78. Rotating sleeves 710 are symmetrically rotatably mounted on the inner side of the fixing rod 79. A strip plate 711 is fixedly connected to the bottom of the rotating sleeve 710. A pressing roller 712 is rotatably mounted at the bottom end of the strip plate 711. An inner strip 713 is fixedly connected to the middle of the strip plate 711. A third spring 714 is fixedly connected between two adjacent inner strips 713.

[0061] Embodiment 2: As Figures 10 - 12 shown, the operator first rotates the double-headed lead screws 73 on both sides. The double-headed lead screws 73 are in contact with the inner wall of the side frame 2 and do not affect the up and down adjustment. When the double-headed lead screws 73 rotate, the front and rear mounting blocks 75 move longitudinally closer to each other. The mounting blocks 75 on both sides move synchronously. The two horizontally arranged mounting blocks 75 drive the inner pressing plate 76 to move, so as to realize the adjustment of the two pressing plates 76 approaching each other, which is convenient for adapting to the front and rear positions of the automotive interior main body 8 and pressing.

[0062] After adjustment, the operator loosens the double-headed lead screws 73 and then rotates the two screw rod portions 71. When the screw rod portions 71 rotate, the cross bar 72 moves downward. The double-headed lead screw 73 slides inside the vertical groove 74. The cross bar 72 drives the double-headed lead screw 73, the mounting blocks 75 and the pressing plate 76 to move downward. When the pressing plate 76 moves downward, the pressing roller 712 first contacts the automotive interior main body 8. The pressing roller 712 drives the strip plate 711 to tilt and deflect. The strip plate 711 drives the rotating sleeve 710 to rotate on the outside of the fixing rod 79, realizing the separation of the two strip plates 711 in a V shape. The strip plate 711 drives the inner strip 713 to move. The two inner strips 713 stretch the third spring 714. When the pressing rod portion 77 presses on the automotive interior main body 8, the elastic force of the third spring 714 makes the strip plate 711 and the pressing roller 712 also press the surface of the automotive interior main body 8, thus realizing the stable positioning of the automotive interior main body 8, which is convenient for subsequent color difference detection.

[0063] Working principle: When using this device, first, as Figures 1 - 12As shown, the color difference meter main body 9 is installed between the left clamping block 612 and the right clamping block 613 and is fixed by bolts. The operator first places the printed automotive interior main body 8 on the top of the operation table 1 so that the detection position is flush with the color difference meter main body 9. The operator first rotates the double-headed lead screws 73 on both sides to move the two pressure plates 76 closer to each other. The operator loosens the double-headed lead screws 73 and then rotates the two screw rod parts 71. The cross bar 72 drives the double-headed lead screws 73, the mounting block 75, and the pressure plate 76 to move downward. When the pressure rod part 77 presses on the automotive interior main body 8, the elastic force of the third spring 714 causes the strip plate 711 and the pressure roller 712 to also tightly press the surface of the automotive interior main body 8, thus realizing the stable positioning of the automotive interior main body 8. Then, the electric push rod 3, the linear guide rail 62, and the hydraulic rod 64 are started. When the moving seat 63 moves linearly, it will drive the vertical plate 66 to move, and the color difference meter main body 9 drives the cleaning ring 619 to move, facilitating the cleaning ring 619 to first wipe and clean the detection position of the automotive interior main body 8. At the same time, when the arc becomes convex, the detection end 91 and the color difference meter main body 9 will be forced to move upward. The color difference meter main body 9 drives the slider 610 to move upward through the left clamping block 612, and the elastic force of the first spring 611 acts on the slider 610 in the opposite direction, so that the color difference meter main body 9 and the detection end 91 always tightly press the surface of the automotive interior main body 8 for detection, and the positioning plate 617 tightly presses and fixes the color difference meter main body 9, thereby reducing the displacement of the color difference meter main body 9 during detection.
