Description

Technical Field

[0001] The utility model relates to the technical field of coating detection, in particular to a multi-station powder coating performance detection device. Background Technique

[0002] It is indeed necessary to perform coating hardness detection on thermosetting powder after production. This is because coating hardness detection is to evaluate the hardness of the coating, test the ability of the coating to resist external force wear and shear force, and is an important parameter for evaluating the compressive capacity of thermosetting powder materials.

[0003] When our company is actually operating, a coating hardness detection device is used for hardness performance detection, and the following problems exist in its detection:

[0004] The lower end of the detection head of its device is a conical structure, and its contact with the thermosetting powder coating (the coating is attached to the carrier plate) is point contact. The point contact extrusion only tests the hardness of a very small point on the coating, which may lead to incomplete measurement results and cannot fully reflect the overall hardness condition of the coating. Therefore, it is necessary to detect each point of the coating. Generally, dozens or even hundreds of points need to be selected for detection, which is troublesome and time-consuming.

[0005] During each detection, it is necessary to manually move the carrier plate for point-changing detection, making the entire detection process rather troublesome and cumbersome.

[0006] It is not possible to detect the coatings on multiple carrier plates simultaneously, resulting in low detection efficiency.

[0007] Therefore, this application provides a multi-station powder coating performance detection device to meet the requirements. Content of the Utility Model

[0008] The purpose of this application is to provide a multi-station powder coating performance detection device for solving the technical problems raised in the above background.

[0009] To achieve the above object, the present application provides the following technical solution: A multi-station powder coating performance detection device, including a bottom plate rotatably arranged in a circle with no less than three carrier platforms. The upper ends of multiple said carrier platforms are all provided with circular grooves adapted to the carrier plates. A positioning magnet magnetically fixed to the carrier plate is installed at the bottom of the inner cavity of the circular groove. A driving motor is fixed at the center of the bottom plate through a mounting frame. A screw rod is installed on the output shaft of the driving motor, and a one-way gear is fixedly sleeved on the screw rod. The one-way gear is engaged with driving teeth circumferentially arranged on the outer walls of multiple said carrier platforms. A threaded tube is threadedly sleeved on the screw rod, and the threaded tube is fixedly embedded in a movable plate. The movable plate is slidably penetrated by multiple vertical rods installed at the lower end of the mounting frame. Multiple mounting plates are circumferentially arranged on the movable plate. A second magnet is fixed at the top of the mounting cavity of each mounting plate. A cross plate is arranged in the mounting cavity of each mounting plate, and a first magnet is installed at the upper end of the cross plate. The opposite ends of the first magnet and the second magnet have the same magnetic poles. A vertical plate is fixed at the lower end of the cross plate, and the vertical plate slidably penetrates the mounting plate. A pressing plate with a flat bottom is arranged at the lower end of the vertical plate;

[0010] A first baffle and a second baffle are installed in the inner cavity of the one-way gear. The first baffle is fixedly installed in the inner wall cavity of the inner ring of the one-way gear. The second baffle is fixed on the screw rod, and the upper and lower ends of the second baffle are slidably connected to the inner wall of the inner ring of the one-way gear;

[0011] The driving motor is electrically connected to a PLC controller arranged on the bottom plate.

[0012] As a preferred implementation manner in this embodiment, the pressing plate includes a first plate body in the middle and second plate bodies on both sides of the first plate body. The first plate body is fixedly installed with the vertical plate, and the two second plate bodies are detachably installed with the vertical plate.

[0013] As a preferred implementation manner in this embodiment, I-shaped cavities are arranged on both side walls of the vertical plate. T-shaped chutes are arranged on the outer walls of the two second plate bodies. Two T-shaped sliders are slidably arranged in the T-shaped chutes, and the two T-shaped sliders are fixedly connected to corresponding external hand-held blocks. The two hand-held blocks are respectively fixedly connected to the outer wall of the vertical plate through springs. An activity cavity adapted to the second plate body is arranged in the inner cavity of the vertical plate.

[0014] As a preferred implementation manner in this embodiment, a blanking opening is arranged on the circular groove.

[0015] In summary, the technical effects and advantages of the present utility model:

[0016] The structure of the utility model is reasonable, and it can detect the coatings on multiple carrier plates simultaneously, improving the detection efficiency. Moreover, it adopts surface contact extrusion detection. Surface extrusion can test the hardness of a larger area of the coating, which can better reflect the overall hardness of the coating, rather than being limited to the hardness of a small point and without the need for dozens or hundreds of detections. At the same time, surface contact can reduce the single-point hardness test error caused by the unevenness, impurities or micro-defects on the coating surface. After each detection, it automatically drives the carrier plate to rotate and change positions without manual operation, making the whole process convenient and fast;

[0017] In the utility model, the width of the adjustable extrusion plate can be adjusted, thereby changing the contact area with the coating to adapt to the properties, thickness of the coating material and the required test accuracy. At the same time, the overall weight of the vertical plate remains unchanged, so that the extrusion force acting on the coating remains unchanged, which is beneficial to improving the detection accuracy.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0026] Embodiment: Refer to Figures 1-5 A multi-station powder coating performance detection device shown in the figure, including a bottom plate 1 provided with no less than three carrier platforms 2 arranged to rotate circumferentially. Circular grooves adapted to the carrier plates are provided at the upper ends of the plurality of carrier platforms 2. A positioning magnet 17 magnetically fixed to the carrier plate is installed at the bottom of the inner cavity of the circular groove. A driving motor 4 is fixed at the axis of the bottom plate 1 through a mounting frame. A screw rod 7 is installed on the output shaft of the driving motor 4, and a one-way gear 8 is fixedly sleeved on the screw rod 7. The one-way gear 8 is engaged with driving teeth 3 arranged circumferentially on the outer walls of the plurality of carrier platforms 2. A threaded tube 9 is threadedly sleeved on the screw rod 7, and the threaded tube 9 is fixedly embedded in a movable plate 6. The movable plate 6 is slidably penetrated by a plurality of vertical rods 5 installed at the lower end of the mounting frame. A plurality of mounting plates 10 are arranged circumferentially on the movable plate 6. A second magnet 15 is fixed at the top of the mounting cavity of each mounting plate 10. A cross plate 11 is arranged in the mounting cavity of each mounting plate 10, and a first magnet 12 is installed at the upper end of the cross plate 11. The opposite ends of the first magnet 12 and the second magnet 15 have the same magnetic poles. A vertical plate 13 is fixed at the lower end of the cross plate 11, and the vertical plate 13 slidably penetrates the mounting plate 10. A pressing plate 14 with a flat bottom is arranged at the lower end of the vertical plate 13;

[0027] A first baffle 81 and a second baffle 82 are installed in the inner cavity of the one-way gear 8. The first baffle 81 is fixedly installed in the inner ring wall cavity of the one-way gear 8, and the second baffle 82 is fixed on the screw rod 7. The upper and lower ends of the second baffle 82 are slidably connected to the inner ring wall of the one-way gear 8;

[0028] The driving motor 4 is electrically connected to a PLC controller arranged on the bottom plate 1.

[0029] During use, the carrier plates with multiple thermosetting powder coatings of a certain thickness are respectively placed in the corresponding circular grooves, with the coated end facing upward. During operation, the driving motor 4 is controlled to rotate, and the screw 7 rotates. The mounting plate 10 is driven downward by the threaded tube 9 (at this time, the second baffle 82 provided on the screw 7 rotates and contacts the first baffle 81, but the one-way gear 8 cannot drive the stage 2 to rotate). When the lower end of the pressing plate 14 contacts the upper end surface of the coating, the mounting plate 10 continues to descend a distance L1. At this time, the distance between the two magnets changes, and the repulsive force generated between the two magnets (the magnitude of this repulsive force is the standard pressure that a qualified coating can withstand) acts to cause the lower end of the pressing plate 14 to press on the coating. After the pressing is completed, the driving motor 4 rotates in the reverse direction. When rotating in the reverse direction, the mounting plate 10 moves upward driven by the threaded tube 9, and at this time, the second contact plate 82 moves in the reverse direction. When the mounting plate 10 pushes the cross plate 11 upward for a short distance (i.e., the upper end of the pressing plate 14 contacts and separates from the upper end of the coating), at this time, the second baffle 82 moving in the reverse direction contacts the first baffle 81, and the one-way gear 8 drives the stage 2 to rotate. When the mounting plate 10 stops moving upward (i.e., when it moves to the initial position), the rotation of the stage 2 stops. At this time, the position of the pressing point of the coating changes. The driving motor 4 rotates forward, and the mounting plate 10 moves downward, causing the pressing plate 14 to press on the coating (after the pressing is completed, it can be observed whether an indentation is generated. If an indentation is generated, it proves that this coating is unqualified). Repeating this process, the coating can be detected at multiple points. Usually, it only needs to be detected at multiple points 4 to 8 times. Since surface contact pressing is adopted, surface pressing can test the hardness of a larger area of the coating, can better reflect the overall hardness condition of the coating, rather than being limited to the hardness of a small point and without the need for dozens or hundreds of detections. At the same time, surface contact can reduce the single-point hardness test error caused by the unevenness, impurities or micro-defects on the coating surface. After each detection, it automatically drives the carrier plate to rotate and change positions without manual operation, making the whole process convenient and fast. Moreover, multiple workstations are set up, and the coatings on multiple carrier plates can be detected simultaneously, improving the detection efficiency;

[0030] The positioning magnet 17 is set, and the carrier plate is magnetically fixed through the positioning magnet 17 to ensure the stability of the carrier plate 17.

[0031] It should be noted that: First, the distance of L1 of this device can also be set according to the control of the PLC controller. When changing positions and detecting each time as needed, the distance of L1 can be controlled to increase continuously to detect the ultimate pressure that the coating can withstand. Second, L1 should not be too large. If it is too large, when the extrusion plate 14 contacts the coating and the mounting plate 10 moves upward, the situation that the carrier table 2 rotates relative to the extrusion plate 14 is likely to occur, which is likely to cause scratches on the surface of the coating. To avoid this situation, when the mounting plate 10 moves upward, after the mounting plate 10 drives the cross plate 11 to move upward, that is, after the lower end of the extrusion plate 14 contacts and separates from the coating, the second baffle 82 contacts the first baffle 81 to rotate the carrier table 2. Third, the first magnet 12 and the second magnet 15 can be magnets, electromagnets, or a combination of both. Fourth, the cooperation of the one-way gear 8 and the driving gear 3 makes the power source consistent with the power source for the rotation of the screw 7, reducing the number of power sources, that is, the number of driving motors 4, which can reduce costs and reduce the equipment maintenance frequency. Fifth, balls can be arranged at the upper and lower ends of the second baffle 82 to reduce the friction with the one-way gear 8. Sixth, the lower ends of multiple vertical rods 5 are fixedly connected to a reinforcing ring arranged outside the screw 7, which can connect multiple vertical rods 5 into a whole and increase the structural strength.

[0032] As a preferred implementation manner in this embodiment, as Figure 4 shown, the extrusion plate 14 includes a first plate body 141 located in the middle and second plate bodies 142 located on both sides of the first plate body 141. The first plate body 141 is fixedly installed with the vertical plate 13, and the two second plate bodies 142 are detachably installed with the vertical plate 13.

[0033] The extrusion plate 14 is composed of a first plate body 141 and two second plate bodies 142. According to needs, the width of the extrusion plate 14 is adjusted (one or two second plate bodies 142 are removed), and thus the contact area with the coating is changed (the adjustable contact area allows the tester to select an appropriate contact area according to the properties, thickness of the coating material, and the required test accuracy, which enables the surface contact extrusion method to adapt to different types of coating materials, whether it is a thin coating or a thick coating, and can conduct effective tests).

[0034] As a preferred implementation manner in this embodiment, as Figure 4 shown, I-shaped cavities 145 are arranged on both side walls of the vertical plate 13. T-shaped chutes are arranged on the outer walls of the two second plate bodies 142, and two T-shaped sliders 144 are slidably arranged in the T-shaped chutes. The two T-shaped sliders 144 are fixedly connected to corresponding external hand-held blocks 143, and the two hand-held blocks 143 are respectively fixedly connected to the outer wall of the vertical plate 13 through springs 146. An activity cavity adapted to the second plate body 142 is arranged in the inner cavity of the vertical plate 13.

[0035] When adjusting the contact area of the extrusion plate 14, pinch the two hand-holding blocks 143 with fingers and make the two hand-holding blocks 143 move relatively to compress the spring 146. After the hand-holding block 143 moves out of the lower bayonet of the I-shaped cavity 145, move the second plate body 142 upward. After moving in place, release the fingers. Under the elastic force of the spring 146, the hand-holding block 143 moves into the upper bayonet. When pressing down, the lower end of the second plate body 142 will not be in contact with the coating. At the same time, since the weight of the second plate body 142 still acts on the vertical plate 13, after the adjustment is completed, the overall weight of the vertical plate 13 remains unchanged, so that the extrusion force acting on the coating remains unchanged, which is beneficial to improving the detection accuracy.

[0036] As a preferred implementation manner in this embodiment, as Figure 1 shown, a blanking opening 16 is provided on the circular groove.

[0037] The operator can put his hand into the blanking opening 16 to facilitate the fingers to support the bottom of the carrier plate, and then it is convenient to remove the carrier plate from the circular groove.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
