Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of plate edge sealing defect detection, and in particular to a plate edge sealing defect detection device. BACKGROUND

[0002] In the process of edge sealing by using an edge sealing machine, the edge sealing effect may be poor or the plate may be damaged due to factors such as equipment debugging, thereby causing defects in the furniture after edge sealing, affecting product quality. Currently, the plate edge sealing defects caused by abnormal conditions of the edge sealing machine during production are mainly detected by manual online inspection or manual inspection. In the case of automatic production without manual inspection, plate edge sealing defects may be caused by machine failure. If the defects are not discovered in time, defective products may be continuously produced. When the defects are discovered in the downstream process, the defective products can only be reworked or discarded, resulting in waste of materials and labor and causing losses.

[0003] According to the plate edge sealing defect monitoring mechanism disclosed in the patent document with the publication number CN209911246U, it includes a fixed frame, two visual detection devices, two partitions and two light source assemblies. The two partitions are located on the fixed frame, and a transmission channel is formed between the two partitions for transmitting plates. The first installation chamber and the second installation chamber are formed by connecting the two partitions to the fixed frame. The first installation chamber and the second installation chamber are located on both sides of the transmission channel. The two visual detection devices are located in the first installation chamber and the second installation chamber, respectively. The two light source assemblies are located in the first installation chamber and the second installation chamber, respectively. The light source assembly is located on one side of the visual detection device. In use, the transmission device in the transmission channel transports the plate. The transmission device can be a conveyor belt. The two light source assemblies in the embodiment cooperate with the visual detection devices located in the same chamber to provide sufficient shooting light for the visual detection devices, so that the visual detection devices work in a better shooting environment. For the above technical solution, although the visual detection device is provided with a better working environment, the plate cannot be fixed and adjusted at the same time.
