DETAILED DESCRIPTION

[0019] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0020] Plywood, also known as multi-layer board or plywood, is made of multiple layers of thin wood sheets glued in the vertical direction of the fibers. It has the characteristics of stable structure, high strength, small deformation and easy processing. It is widely used in furniture, construction and packaging industries. In production, veneer quality control is crucial. After the logs are cut by a rotary cutter, qualified veneers need to be glued and hot-pressed for shaping, but log defects such as uneven edges, wormholes, and uneven board thickness will affect the quality of the finished product. At present, veneer detection mainly relies on visual or optical methods, and these methods will have certain problems during detection. First, for veneers with uneven thickness, the above-mentioned detection method cannot accurately detect them, resulting in veneers with uneven thickness being misjudged as qualified products. Secondly, the above-mentioned detection method also has the problem of obvious low efficiency. A veneer defect detection device is provided in the present invention to solve the above problems.

[0021] like Figure 1-Figure 4 As shown, in some embodiments, a single board defect detection device includes a transfer assembly 100 and a bearing assembly 300. Specifically, the transfer assembly 100 is arranged on the upper part of the bearing assembly 300 to achieve efficient transfer of the single board.

[0022] In particular, a loading area, a testing area and a picking area are respectively provided in the carrier assembly 300. The testing area is located between the loading area and the picking area, and a testing assembly is specially provided in the testing area, which detects the light transmittance of the single board and identifies defects in the single board, such as cracks, impurities and uneven thickness. In this way, qualified single boards are detected.

[0023] Specifically, the detection area includes a light-transmitting plate 800 and a light source mechanism 700. The light source mechanism 700 is located below the light-transmitting plate 800 and is responsible for emitting light to the single board to be detected placed on the upper part of the light-transmitting plate 800. In order to ensure that the light-transmitting plate 800 can effectively complete its task, it is made of transparent glass material. Such a design not only ensures the transparency of the light-transmitting plate 800, so that the light in the detection process can pass smoothly, but also ensures the strength and durability of the light-transmitting plate 800.

[0024] It is worth noting that by analyzing the light that passes through the veneer, its quality can be evaluated. Specifically, when the light source penetrates the veneer, defects on it, such as wormholes and cracks, will be clearly visible. In addition, by detecting the amount of light that passes through the veneer, it is possible to determine whether the thickness of the veneer is uniform. For veneers with uneven thickness, light spots will appear on their upper parts. Based on the size and distribution of the light spots, it is possible to further determine whether the thickness of the veneer meets the production standards. In this way, the detection accuracy of the veneer can be effectively improved.

[0025] In order to sort the veneers after inspection, a conveyor assembly 400 and a material picking assembly 500 are provided in the sorting area. The material picking assembly 500 is arranged above the conveyor assembly 400, and the veneers that fail the inspection are removed by the material picking assembly 500. In this way, the unqualified veneers are removed in time, and the veneers that pass the inspection continue to be processed or transported by the conveyor assembly 400.

[0026] It should be noted that the veneers that have been peeled and formed are neatly stacked in the loading area. The transfer component 100 is responsible for picking up these veneers one by one and transporting them to the inspection area so that they are laid flat on the light-transmitting plate 800. The light source mechanism 700 then emits strong light from the bottom of the veneer, and a collector is installed above the veneer to analyze the light transmittance of the veneer. In this way, the thickness and defect information of the veneer are fed back to the external processor. After the processor analyzes and processes these data, the subsequent components will perform corresponding processing on the inspected veneer according to the quality of the veneer. Specifically, the transfer component 100 will send the inspected veneers to the picking area, the picking component 500 will remove unqualified veneers, and the conveying component 400 will be responsible for outputting qualified veneers to the outside of the equipment.

[0027] In this process, the light-transmitting plate 800 and the light source mechanism 700 work together to provide accurate feedback on the defects of the single board, and judge the quality of the single board based on the light spots that appear on the single board, thereby improving the accuracy of single board detection. The conveying component 400 and the picking component 500 work together to achieve rapid selection of single boards, thereby improving single board detection efficiency.

[0028] Furthermore, in some embodiments, in order to achieve efficient veneer transportation, a plurality of clamping mechanisms 120 and driving mechanisms are provided in the transport assembly 100.

The driving mechanism is responsible for driving these clamping mechanisms 120 to ensure that the veneers can smoothly pass from the loading area through the testing area and finally reach the picking area during the testing process. In this way, the equipment can achieve continuous, efficient and accurate testing and transportation of veneers.

In particular, a first motor 130 is provided at one end of the transmission screw 140, and the first motor 130 is fixedly connected to one of the support plates 110 to ensure that the first motor 130 can output power stably.

[0030] Two connecting sliders 160 are arranged along the transmission screw 140, and the connecting sliders 160 are connected to the transmission screw 140 by threads, so as to ensure that the sliders can move smoothly along the screw. The two ends of the connecting slider 160 are respectively slidably connected to the two connecting polished rods 150, so that the connecting slider 160 can move freely on the connecting polished rods 150. The first motor 130 drives the transmission screw 140 to rotate, thereby driving the connecting slider 160 to move, thereby realizing precise control of the device.

[0031] In addition, the two ends of the connecting slider 160 are respectively provided with a clamping mechanism 120, and the clamping mechanism 120 is connected to the lower part of the connecting slider 160.

[0035] In particular, the carrier plate 320 is provided with a baffle 330, a detection trough 340, a discharge trough 360 and two guide troughs 370. Among them, the baffle 330 is arranged between the loading area and the detection area, and is fixed by a threaded connection to separate the two areas. The detection trough 340 is arranged in the detection area, and defects of the single board are detected in this area. The discharge trough 360 and the guide trough 370 are located in the picking area, which are used to unload and sort the single board after detection. The two guide troughs 370 are symmetrically arranged along the longitudinal center line of the carrier plate 320 to ensure that the material is stably transported out of the detection equipment. The discharge trough 360 is arranged on the upper part of the guide trough 370, so that unqualified single boards can be smoothly removed from the conveying component 400. The conveying component 400 is connected to the guide trough 370, and the picking component 500 corresponds to the discharge trough 360.
