Description

Technical Field

[0001] The invention relates to the technical field of optical detection, in particular to a quilt surface detection device. Background Art

[0002] During the production process, quilts go through a quilting process to sew the cotton core and the quilt shell together so that the cotton core and the quilt shell can be tightly fixed to ensure that the cotton core can be evenly arranged in the quilt shell. After the quilt is quilted, it is necessary to inspect the surface for defects to determine whether there are any excess threads or oil stains. However, the current inspection method is for workers to observe the surface of the quilt with their naked eyes to see if there are any defects. This inspection method is not only inefficient, but also workers are prone to fatigue during long-term operations, resulting in missed inspections.

[0003] In the prior art, the surface of the quilt is scanned by some camera acquisition and infrared scanning methods to detect whether there are stains and protrusions that do not meet the production standards. In this process, the quilt needs to be spread out flat. In order to prevent the quilt from having wrinkles that affect the detection results, some clamps are needed to clamp and fix the quilt to spread the quilt flat. Therefore, it takes a lot of time to fix the structure when sending the quilt in and out of the detection table, resulting in low quilt detection efficiency. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a quilt surface detection device to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. After the quilt is received on the outside of the detection table by the unfolding component, the quilt is unfolded by the driving component and then sent back to the inside of the detection table. The top of the quilt is flattened by two groups of pressure rollers and fixed at the two side edges of the quilt to prevent the quilt from moving and preventing the quilt from being uneven and wrinkled. The camera device and the infrared switch are used to detect whether there is dirt on the surface of the quilt and whether there are any raised and uneven positions. After the detection is completed, the quilt is slid out of the detection table by the pallet.

[0009] Furthermore, the driving assembly also includes a tooth plate, and the outer sides of the two gears are meshed with tooth plates. The support plate is fixed with a limit frame corresponding to the position of the tooth plate, and the tooth plate slides along the limit frame. A transmission belt is installed at the center of the gear, and the pulley at the other end of the transmission belt is connected to the rotating shaft of the skateboard and the extension plate through a telescopic connecting rod.

[0010] Furthermore, a moving opening is fixed on the top of the tooth plate, and a card block is slidably connected in the moving opening, the card block has a notch facing outward, an insert plate is fixed to one end of the pressure roller corresponding to the card block, and the insert plate is inserted into the inside of the card block opening, a second spring is fixed on the top of the moving opening, and the other end of the second spring is fixedly connected to the card block.

[0015] Beneficial effects of the present invention:

[0016] 1. Before the support plate is sent in, the present invention needs to rotate the unfolding plate into a flat state through the driving assembly. At this time, the plane of the unfolding plate is flush with the top of the support plate and higher than the detection table. The bottom of the unfolding plate is in sliding contact with the detection table and will not collide with the detection table, making it convenient to send the unfolded quilt into the interior of the detection table.

[0017] 2. In the present invention, the lifting and lowering movement of the tooth plate is guided and limited by the limit frame. The two sets of baffles on the support plate can adjust their positions according to the width of the quilt and are kept squeezed on the two ends of the quilt by the first spring. At the same time, the extension plate and the slide plate can slide along the moving groove of the unfolding plate to maintain the connection between the baffle and the unfolding plate. The rotation connection between the extension plate and the slide plate is connected to the transmission belt pulley through a telescopic connecting rod, that is, the telescopic rod-style connecting piece connects the pulley of the transmission belt and the rotation connection between the extension plate and the slide plate, so that the rotation of the gear can drive the flipping of the unfolding plate. At the same time, no movement interference will occur when the position of the baffle changes, and the connection is always maintained.

[0018] 3. The present invention uses the transmission belt to drive the extension plate and the slide plate to rotate, and then the unfolding plate is transformed from a flat shape to a vertical shape. The gears are meshed with the toothed plate to drive the pressure roller to rise, making it convenient for people to put the quilt on the support plate in a drying manner. Then, through the meshing of the gears and the transmission of the rotating belt, as well as the movement of the toothed plate, the unfolding plate rotates to unfold the quilt, and the pressure roller squeezes the top of the quilt. The other end of the pressure roller moves up and down and slides along the vertical plate. When the pressure roller descends to squeeze the top of the quilt, the block and the plug plate slide along the moving opening according to the thickness of the quilt to compress the second spring. Therefore, the quilt can be used for detecting quilts of different thicknesses.

[0019] 4. The present invention is connected by a telescopic connecting frame, and the infrared switch slides synchronously along the inside of the first sliding frame to detect the flatness of the top of the quilt. The first sliding frame is driven by an electric push rod to move corresponding to the bottom position of the pressure roller, so that it is suitable for detecting quilts of different thicknesses.

[0020] 5. Compared with the prior art, the present invention receives the quilt outside the inspection table through the unfolding component, unfolds the quilt through the driving component, and then sends it back to the inside of the inspection table. Two sets of pressure rollers flatten the top of the quilt and fix it on the two side edges of the quilt to prevent the quilt from moving and preventing it from being uneven and wrinkled. The camera device and the infrared switch are used to detect whether the surface of the quilt is dirty and whether there are any raised and uneven positions. After the detection is completed, it is slid out of the inspection table through the pallet. In the whole process, the quilt is more convenient to send in and out, which improves the detection efficiency of the quilt. BRIEF DESCRIPTION OF THE DRAWINGS

The technical principle of the camera device 3 is the same as the working principle of the CCD camera in the patent CN219475426U, and the surface photos of the quilt located in the detection space are taken. The computer compares the taken photos with the pre-set standard photos to determine whether there are defects and oil stains on the surface of the quilt. When using the device, the unfolding component 4 is moved out of the detection table 1, the quilt is placed on the detection table 1, and the quilt is unfolded by the driving component 5. After the two sides of the quilt are pressed, it is sent back to the detection table 1. The defects, stains and whether there are protrusions on the surface of the quilt are detected by the camera device 3 and the infrared switch 34 in the detection table 1. After the detection is completed, the quilt is sent out by the unfolding component 4.

The knob (not shown in the figure) provided on the gear 53 on one side is turned. The two gears 53 are rotated, and the extension plate 49 and the slide plate 47 are rotated through the transmission of the transmission belt 54, so that the unfolding plate 45 is changed from a flat shape to a vertical shape. The gear 53 is meshed with the tooth plate 55 to drive the roller 46 to rise, so that it is convenient for people to put the quilt on the support plate 41 in a drying manner. Then, through the meshing of the gear 53 and the transmission of the rotating belt, as well as the movement of the tooth plate 55, the unfolding plate 45 is rotated to unfold the quilt, and the roller 46 squeezes the top of the quilt.
