Description

Technical Field

[0001] This invention relates to the field of coating surface inspection technology, and in particular to a color difference detection device for zinc-plated coating surfaces. Background Technology

[0002] Electroplating, such as zinc plating, is typically used as the final treatment for metal surfaces. Color difference detection devices compare the product's color to a standard sample to determine if the product is up to standard. Currently, most color difference detection devices use handheld color difference meters for scanning.

[0003] Color difference detection on the coating surface of cylindrical metal bars requires holding the color difference detection device while simultaneously rotating the cylindrical metal bar for scanning. These cylindrical bars are heavy and numerous, increasing the workload and labor intensity of workers. Prolonged operation leads to hand fatigue, causing instability of the handheld color difference detection device and affecting detection accuracy. Furthermore, while some devices exist for detecting color difference in the coating of cylindrical bars, these devices are relatively limited in function, lacking features such as motorized feeding and the ability to separately transfer defective products. They typically require frequent manual handling of the bars, resulting in high manual labor intensity and low detection efficiency.

[0004] Therefore, this invention proposes a color difference detection device for the surface of a galvanized coating. Summary of the Invention

[0009] As a further description of the above technical solution: One end of the guide shaft is provided with a sliding hole. A guide tube is fixedly connected to the back of the pad and sleeved in the sliding hole. The guide tube and the sliding hole are slidably connected.

The first transmission belt can transport multiple bars through the partition. The lifting plate can lift one of the bars to the detection position. When the second transmission belt is running, it can transfer unqualified bars out of the detection station through the arc plate. That is to say, when detecting the color difference of the coating of a large number of bars, a row of bars is placed on the first transmission belt manually, and then the controller on this device is started to perform sequential color difference detection on the bars on the first transmission belt. This setup can greatly reduce the frequency and labor intensity of manual detection operations, while improving the efficiency of color difference detection.

[0015] 2. In this invention, a corrector is provided, which includes a push plate, a positioning seat, a wedge plate, a spring, and a transmission plate.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figure 1-6 A color difference detection device for galvanized coating surfaces includes a base plate 1 and a color difference detector 150. The color difference detector 150 is a common instrument in the field of visual inspection and visual measurement, specifically used for quantifying and measuring color differences. It converts color information into measurable and comparable digital data by simulating human visual perception, thereby achieving an objective assessment of product color quality. Its detection principle is that the light source on the color difference detector 150 illuminates the sample surface, and the light reflected from the sample surface is collected and decomposed by the optical collection system inside the instrument. Then, the analog signal processed by the signal conversion module is converted into a digital signal. The digital signal is then further processed for color, and the processing result is compared with a standard color sample to determine the color difference.

[0021] The top of the base plate 1 is connected to two parallel conveyors 1 via two vertical plates 2. Each conveyor 1 is a belt conveyor, comprising a horizontally distributed conveyor belt 3. The outer periphery of the conveyor belt 3 is fixedly connected to circumferentially spaced partitions 31. In use, bar stock is placed between the two partitions 31 on the two conveyor belts 3. When the two parallel conveyor belts 3 rotate, they cause the bar stock placed between adjacent partitions 31 to shift horizontally. The surface of this bar stock contains a galvanized layer. The top wall of the vertical plate 2 has a clearance groove 21, within which the conveyor 1 is located. A row of idlers 130 located within the conveyor belt 3 is installed in the clearance groove 21. The idlers 130 support the conveyor belt 3, and the clearance groove 21 limits the movement of the conveyor belt 3.

[0022] Two lifting plates 4 are respectively located on the outer sides of the two upright plates 2 above the base plate 1. The inner side of the lifting plate 4 is fixedly connected to the support plate 6 through the connecting plate 5. Two support wheels 7 are connected to one side of the support plate 6. The support wheels 7 are fixedly covered with protective rubber sleeves. Specifically, one side of the support plate 6 is rotatably connected to the wheel axle, and the wheel axle is fixedly connected to the middle of the support wheel 7. A servo motor 2 is fixedly installed on the other side of the support plate 6. The output shaft of the servo motor 2 is fixedly connected to one end of one of the wheel axles. When the bar stock mentioned above moves horizontally to the top of the support wheel 7, the two lifting plates 4 rise synchronously, and the support wheel 7 will vertically lift the bar stock.

[0023] The base plate 1 has a guide post 11 fixedly connected to its top. The lifting plate 4 is a tubular structure and is sleeved on the outside of the guide post 11. The lifting plate 4 and the guide post 11 are slidably connected. The two vertical plates 2 are laterally slidably connected to the outer sides of the two vertical plates 2. Specifically, the outer side of the vertical plates 2 is fixedly connected to a sliding sleeve sleeved on the outside of the transmission rod 104 through a positioning plate. The sliding sleeve and the transmission rod 104 are slidably connected. The inner side of the lifting plate 4 and near the top is fixedly connected to a connecting shaft 41. The connecting shaft 41 is hinged to one end of the transmission rod 104 through a connecting rod 140. The base 12 is fixedly connected to one end of the base plate 1. An electric push rod 105 is fixedly connected to one side of the base 12. The actuating end of the electric push rod 105 is fixedly connected to the other end of the transmission rod 104 through a connecting beam 1051. When the electric push rod 105 moves, it can drive the two transmission rods 104 to move horizontally through the connecting beam 1051. When the two transmission rods 104 move horizontally, they can drive the two lifting plates 4 to rise and fall synchronously through the connecting rod 140.

[0024] A crossbeam 8 is fixedly installed above the two lifting plates 4. Both ends of the crossbeam 8 are fixedly connected to the tops of two guide columns 11 via short rods. A cross plate 9 located above the support wheel 7 is fixedly connected to one side of the crossbeam 8 via a connecting frame. A color difference detector 150 is connected to the bottom of the cross plate 9 via a slider 101. A connecting sleeve is welded to the top of the slider 101 and fitted onto the outside of the cross plate 9. The connecting sleeve and the cross plate 9 are slidably connected. A lead screw is screwed through and connected to the slider 101. The two ends of the lead screw are rotatably connected to ear plates fixedly connected to the two ends of the cross plate 9. A servo motor is fixedly installed on the outer side of one of the ear plates. The output shaft of the servo motor is fixedly connected to one end of the lead screw. The servo motor provides driving force to the rotation of the lead screw. When the lifted bar is close to the bottom of the color difference detector 150, the slider 101 moves back and forth, which can drive the color difference detector 150 to move. When the color difference detector 150 moves, it can perform color difference detection on the upper surface of the bar. When a support wheel 7 on the control plate 6 is rotated, it can drive the bar to rotate, thereby enabling comprehensive color difference detection of the galvanized layer on the outer periphery of the bar.

[0025] A second conveyor is installed above the base plate 1. The second conveyor is also a belt conveyor. The function of the second conveyor is to transfer the bar stock with color difference away. The second conveyor includes a horizontally distributed conveyor belt 102 located diagonally below the color difference detector 150. The two sides of the frame on the second conveyor are fixedly connected to the top wall of the base plate 1 by L-shaped beams. The outer periphery of the second conveyor belt 102 is fixedly connected with circumferentially evenly distributed arc plates 1021. When the second conveyor belt 102 is running, it will transfer the bar stock with color difference after detection through one of the arc plates 1021.

[0026] The partition 31 has a trapezoidal cross-section with the smaller end facing outwards. Arc-shaped spring rods 311 are fixedly connected to both sides of the partition 31 and near the top. The free end of the arc-shaped spring rods 311 faces the bottom of the partition 31. The arc-shaped spring rods 311 are made of spring steel and are covered with protective rubber sleeves. The function of the arc-shaped spring rods 311 is to elastically limit the movement of bars with different outer diameters, so as to facilitate the stable transmission of bars by the conveyor belt 3.

[0027] Furthermore, a baffle 1022 is fixedly connected to the outer peripheral wall of the second transmission belt 102, located on one side of the arc plate 1021 and arranged along the length of the second transmission belt 102. The baffle 1022 prevents the bar material hooked by the arc plate 1021 from rolling freely. The baffle 1022 is made of rubber. A buffer pad 10211 is bonded to the inner side of the arc plate 1021. The buffer pad 10211 is used to buffer and protect the bar material.

[0028] In summary, the function of transmitter one is to feed the material, and the function of transmitter two is to transfer the bar stock with color difference problems to the outside. Together with the lifting function of lifting plate 4, the continuity of the detection of a large number of bar stock is greatly improved, thereby improving the detection efficiency.

[0029] A straightener is provided on the base plate 1, located on the outside of the two upright plates 2 and near one end. The function of the straightener is to straighten the row of bars placed on the conveyor belt 3, so that the row of bars is in a neat state. The straightener includes a push plate 103 that can move laterally. The push plate 103 is parallel to the upright plate 2. There is a push plate 103 on the outside of each of the two upright plates 2. When the two push plates 103 on the outside of the two upright plates 2 move in opposite directions, they can push the row of bars on the conveyor belt 3 to a neat state. This arrangement ensures that the bars subsequently lifted by the lifting plate 4 are within the detection range of the color difference detector 150 during reciprocating motion.

[0030] Specifically, the orthotic device includes a positioning seat 106, a wedge plate 107, a spring 108, and a transmission plate 109. The positioning seat 106 is fixedly mounted on the upper surface of the base plate 1, and a support plate 1061 is fixedly connected to its top. A guide shaft 1031, which passes through the support plate 1061, is fixedly connected to the back of the push plate 103. The guide shaft 1031 and the support plate 1061 are slidably connected. When the guide shaft 1031 moves axially, it can drive the push plate 103 to move. A pad 10311 is provided at one end, and a spring 108 is sleeved on the guide shaft 1031 between the pad 10311 and the support plate 1061. The spring 108 serves to reset the guide shaft 1031. Specifically, when the guide shaft 1031 is pushed to move the push plate 103 towards the adjacent vertical plate 2, the spring 108 will compress, releasing the thrust on the guide shaft 1031. After that, the spring 108 will push the guide shaft 1031 back to its original position through the pad 10311. A wedge plate 107 is located on one side of the pad 10311 and is slidably connected to the support plate 1061. Specifically, a sleeve 10611 is fixedly connected to one side of the support plate 1061 through a limiting plate, and a guide plate 1071 sleeved in the sleeve 10611 is fixedly connected to the bottom wall of the wedge plate 107 through an ear plate. One end of the wedge plate 107 is hinged to one side of the adjacent lifting plate 4 via the transmission plate 109. The inclined surface on the wedge plate 107 is opposite to the pad plate 10311. Thus, when the lifting plate 4 rises, the transmission plate 109 pulls the wedge plate 107. When the wedge plate 107 moves, it uses the inclined surface to push the pad plate 10311, which in turn drives the guide shaft 1031 to move.

[0031] Furthermore, a sliding hole 1032 is provided at one end of the guide shaft 1031. A guide tube 103111 fitted inside the sliding hole 1032 is fixedly connected to the back of the pad 10311. The guide tube 103111 and the sliding hole 1032 are slidably connected. An adjusting shaft 110 is provided through the pad 10311. The adjusting shaft 110 and the pad 10311 are rotatably connected. A baffle 10321 near the bottom end is fixedly connected to the inner wall of the sliding hole 1032. The baffle 10321 and the adjusting shaft 110 are screwed together. When the adjusting shaft 110 rotates, it can adjust the distance between the pad 10311 and the guide shaft 1031. The purpose of this arrangement is to facilitate the adjustment of the position of the push plate 103 according to the length of the bar stock. A handle is welded to one end of the adjusting shaft 110 on one side of the baffle 10321. The adjusting shaft 110 can be easily rotated through the handle.

[0032] In this embodiment, a roller 120 adapted to the inclined plane is provided on the front side of the pad 10311. The roller 120 can eliminate the friction between the inclined plane and the pad 10311.

[0033] Working principle: In use, multiple bars to be tested for color difference are placed on the conveyor belt 3 between the partitions 31 near one end. The conveyor belt 3 supports the bars. When the conveyor is started, the conveyor belt 3 is driven to rotate, and a row of bars will be moved horizontally. When the foremost bar is directly above the two adjacent support wheels 7, the electric push rod 105 is activated. When the electric push rod 105 moves, it drives the transmission rod 104 to move. When the transmission rod 104 moves, it drives the two lifting plates 4 to rise synchronously through the connecting rod 140. The support wheels 7 rise to contact and lift the bars above them, and the bars rise to the color difference detection position. After the color difference detector 150 is positioned below, the servo motor fixedly installed at one end of the support plate 6 is started. The servo motor drives the lead screw to rotate. Under the transmission of the lead screw, the slider 101 moves and drives the color difference detector 150 to move laterally, thereby realizing the color difference detection of the coating on the top wall of the bar. Then, the second servo motor fixedly installed on the outside of one of the support plates 6 is started. The second servo motor drives one of the support wheels 7 to rotate. When the support wheel 7 rotates, it uses friction to drive the bar on it to rotate a certain angle. Then, the lead screw is controlled to reverse, and the color difference detector 150 moves and performs color difference detection on the top wall of the bar. This cycle can be repeated to fully detect the coating on the outer wall of the bar. It should be noted that when the lifting plate 4 rises, it pulls the wedge plate 107 to move via the transmission plate 109. When the wedge plate 107 moves horizontally, it uses the inclined roller 120 on it to push the guide shaft 1031 axially. The axial movement of the guide shaft 1031 drives the push plate 103 to move, which in turn pushes one end of the bar stock on the first transmission belt 3, aligning the bar stock on the first transmission belt. When a bar stock with a color difference is detected, the second transmission device is activated, and the second transmission belt 102 starts operating. The second transmission belt 102 drives one of the arc-shaped plates 1021 to rise from below the bar stock with the color difference. The arc-shaped plate 1021 hooks the bar stock with the color difference onto the second transmission belt 102, and then transports it to a position away from the color difference detector 150, thus transferring the bar stock with the color difference.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
