Description

Technical Field

[0001] The present invention relates to the technical field of invisible car cover production and processing, and more particularly to the technical field of invisible car cover detection, and specifically to a defect detector applied to car cover films. Background Art

[0002] Invisible car cover can improve the brightness of the car body. It can also prevent corrosion and scratches. It is equivalent to a transparent protective film that separates the car paint from the external environment and effectively protects the car paint from the damage of the external environment. At the same time, the invisible car cover has elastic self-repair function. Its raw material comes from TPU. This material has elastic memory repair function and can automatically repair scratches when encountering small scratches. During the production, processing and use of invisible car cover, it is generally necessary to test the invisible car cover to ensure that the invisible car cover is free of creases, bubbles, scratches and other defects to avoid affecting the quality of the car cover.

[0003] Current car cover inspection equipment, such as the patent with application number 202211147432.6, discloses an ultra-transparent car cover light transmission inspection device, including an inspection box, a placement rack, an inspection component and a sealing component. The placement rack is fixedly connected to the inspection box, and the sealing component includes a sealing cover, a fixing seat, a sliding block and a limit seat. The sealing cover is rotatably connected to the inspection box, the fixing seat is fixedly connected to the sealing cover, the sliding block is slidably connected to the fixing seat, and the limit seat is fixedly connected to the inspection box. The limit seat has a limit slot. The car cover is placed in the placement rack, the sealing cover is pulled to rotate the sealing cover relative to the inspection box, and the sealing cover is closed on the inspection box, the position of the sliding block is moved so that the sliding block is inserted into the limit slot, so that the fixing seat and the limit seat are locked, and then the position of the sealing cover is locked, and the inspection component is further enabled to inspect the car cover in a sealed environment to prevent external light from affecting the inspection results;

[0004] For another example, patent 202220355672.4 discloses a TPU film appearance detection device, comprising a base, wherein the top of the base is fixedly connected to a light source table, a first slide groove is provided on one side of the light source table, a second slide groove is provided on the inner wall of the side of the light source table away from the first slide groove, a first slide rod is slidably connected in the second slide groove, an end of the first slide rod away from the second slide groove passes through the first slide groove and is slidably connected, a thread is provided on the end of the first slide rod close to the first slide groove, and a first limiting ring is connected to the first slide rod through a thread. The utility model is provided with a rotatably adjustable positive positioning ring, which can keep the TPU film in the center position, and at the same time can adjust the range of illumination so that the TPU film can completely cover all light sources, preventing other light from being received by the light sensor, thereby improving the detection accuracy;

[0005] Considering the actual needs of invisible car cover during processing and use, the current defect detection equipment still has certain drawbacks, such as:

[0006] The structure is complex and the operation is cumbersome. It is not possible to quickly place and load the car cover, which is not conducive to quickly completing the car cover inspection work to improve the efficiency of car cover placement and use;

[0007] The car cover cannot be unfolded stably, which is not conducive to preventing the car cover from bending, causing damage to the car cover and affecting its use;

[0008] When inspecting the unfolded cover, the impact of the cover's natural curling caused by winding on defect detection cannot be reduced, which is not conducive to improving inspection accuracy;

[0029] 1. This solution is equipped with a clamping platform, a pressure plate, and a rubber pad. The pressure plate slides up and down on the inner side of the fixed plate to clamp the ends of the car cover. At the same time, rubber pads are installed on the opposing surfaces of the pressure plate and the clamping platform to prevent damage to the car cover and facilitate the unfolding and testing of the car cover.

[0030] Furthermore, the clamping platform, pressure plate and other structures can be directly replaced by a second unwinding rod, which is convenient for the unwinding and rewinding inspection of the garment;

[0031] 2. This solution is equipped with a flat roller, which can easily lift the part of the car cover that enters the top surface of the base plate, avoiding friction between the car cover and the base plate at the corners, thereby preventing the car cover from being damaged;

[0032] 3. This solution is provided with a first slide rail, a first fixed frame, and a first unwinding rod. The first slide rail can be used to slide the first fixed frame left and right using the first slider, thereby sliding the first unwinding rod provided on the outside of the first fixed frame. The first unwinding rod can directly insert and place the garment roll, making it convenient to unwind and detect the garment.

[0033] Furthermore, a driving motor, a shaft and a pressure roller are provided. The driving motor can rotate the entire structure of the connecting rod, the shaft and the first unwinding rod, so that the pressure roller arranged on the outer side of the shaft can be used to press the car cover downward to ensure that the car cover fits the surface of the base plate, thereby reducing warping and improving detection accuracy.

[0034] 4. This solution is provided with a support rod, a fixing sleeve, and a limiting rod. Through the rotational connection between the support rod and the shaft rod, the support rod can be rotated to the side of the first unwinding rod to facilitate garment loading. The bottom end of the support rod is rotated to align with the end of the first unwinding rod. By extending and retracting the limiting rod, the limiting rod is engaged with the bottom end of the support rod. The shaft rod, support rod, and first unwinding rod can be combined to enhance structural strength, maintain the parallelism between the pressure roller and the first unwinding rod, and prevent the garment from tilting and causing curling or even bending.

[0035] 5. This solution is provided with a limit ring, a clamping plate, and a pressure block. The pressure block can be pressed against the clamping plate, causing it to slide inward, causing it to lose its grip on the first unwinding rod, allowing the limit ring to slide. Simultaneously, the elastic action of the third and second springs allows the clamping plate to re-clamp the first unwinding rod via the clamping pad, thereby facilitating position detection for car covers of different widths.

[0036] 6. This solution is equipped with a mounting plate, a second slider, a mounting rod, and a light intensity sensing module. The mounting plate is fixed integrally to the first fixing frame, allowing the mounting rod and the light intensity sensing module to move with the first unwinding rod, facilitating the detection of car covers.

[0037] Furthermore, a sliding rod, a third slider and an extension rod are provided. The sliding structure of the second slider on the outer side of the sliding rod facilitates the second slider to slide to the right when the first unwinding rod moves to the leftmost side, thereby ensuring the movement of the first unwinding rod. At the same time, the third slider is fixed to limit the position of the second slider under the elastic action of the fourth spring, so that the light intensity sensing module can receive the refracted light for car clothing detection.

[0038] 7. This solution is equipped with a horizontal plate, a left mounting frame, a right mounting frame, and an adjustment block. The horizontal plate is integrally fixed to the first fixing frame, allowing the left and right mounting frames to move with the first unwinding rod. The adjustment block can be raised or lowered by rotating the adjustment rod to adjust the inclination angle of the left and right mounting frames. This facilitates the use of the light source module and the receiving module for light reflection detection of car covers of different thicknesses.

[0039] 8. This solution is equipped with a fan, a shaping tube and an air duct. The fan is used to blow air, so that the air can be blown to the car cover attached to the surface of the bottom plate through the air duct, which is conducive to ensuring that the car cover is laid flat and avoiding warping, thereby further improving the detection accuracy. At the same time, a honeycomb-shaped honeycomb panel is provided inside the air duct, which is conducive to ensuring that the air is blown out evenly and avoiding vibration of the car cover.
