Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of egg processing, in particular to an automatic optical inspection device for egg product processing. Background Art
[0002] The eggs in the factory are processed in an automated manner. They need to go through three major steps: cleaning, grading and packaging. The grading and screening process includes multiple screening methods such as optical inspection and weighing. Among them, optical inspection is the most mature detection method. An optical inspection lamp is used to illuminate the eggs on the conveyor belt from below, and the image acquisition system above is used to perform real-time analysis on the collected image information to detect whether the eggshell is damaged, whether the eggs are fresh, whether the eggs are fertilized, and other issues.
[0003] Currently, there are various optical inspection equipments for eggs. However, unqualified eggs are usually removed manually after the optical inspection, which is time-consuming and labor-intensive. In addition, manual removal may easily lead to mistaken removal or missed removal.
[0004] After searching, a Chinese patent with patent number CN202222686194.8 discloses an automatic egg screening device. After analyzing the patent, in the optical inspection and screening process of eggs, the device first needs to drive the vertical wall bracket to move horizontally through the straight-moving motor, and use the hydraulic cylinder to extend and retract up and down to grab the abnormal eggs, and then use the straight-moving motor to drive the vertical wall bracket to move horizontally, and move the grabbed eggs to the top of the rubber slide. Finally, the hydraulic cylinder is extended and retracted up and down to place the eggs in the rubber slide for discharge. The operation of this device is relatively cumbersome. Due to the long moving path, the overall optical inspection efficiency is low, and in the process of discharging abnormal eggs, if the conveying mechanism at the bottom continues to run, it is easy to cause the abnormal eggs below to be missed, and then cause the abnormal eggs to be discharged into qualified eggs, affecting the quality. Utility Model Content
[0005] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides an automatic optical inspection device for egg product processing. The automatic optical inspection device facilitates the diversion and transportation of unqualified eggs and qualified eggs through a rejection mechanism movably arranged at the end of the conveyor belt, thereby achieving the purpose of rejection. The device can effectively prevent unqualified eggs from being missed, and the overall optical inspection efficiency is high.
[0006] The utility model is realized by constructing an automatic optical inspection device for egg product processing, comprising a plurality of conveyor belts which are arranged in parallel in a frame body and are kept tensioned for conveying;
[0007] The unloading mechanism is arranged on the top of one side of the frame above the conveyor belt and is used to evenly roll the egg products to the gap between the conveyor belts for transportation;
[0008] The optical inspection device is arranged on the frame at the lower end of the conveyor belt to facilitate the optical inspection of the eggs transported on the conveyor belt;
[0009] The rejecting mechanism is movably arranged on a frame at the end of the conveyor belt to facilitate diversion and transport of eggs transported on the conveyor belt to reject unqualified eggs detected by optical inspection.
[0010] Specifically, the unloading mechanism includes a unloading hopper and a slide plate, wherein the slide plate is arranged on the side of the unloading hopper and is connected to the interior of the unloading hopper, an inclined receiving groove is provided on the top of the slide plate, and the top of the receiving groove is close to the side of the unloading hopper, and a plurality of guide plates are provided in the receiving groove of the slide plate, and the eggs are directly guided from the receiving groove of the slide plate to the gap between the conveyor belts through the guide plates.
[0011] Specifically, the optical inspection and irradiation device includes a mounting slot plate and an irradiation lamp tube arranged in the mounting slot plate. The mounting slot plate is fixed to the bottom of the frame between the unloading mechanism and the rejection mechanism and keeps the mounting direction perpendicular to the conveying direction of the conveyor belt. The irradiation lamp tube is installed in the mounting slot plate to keep the irradiation direction vertically upward to irradiate the conveyor belt and the gap between the conveyor belts.
[0012] Specifically, a cover is installed on the frame just above the light inspection and irradiation device.
[0013] Specifically, the rejection mechanism includes a fixed rod, which is arranged between the frames at the ends of the conveyor belt and is kept perpendicular to the conveying direction of the conveyor belt;
[0014] A plurality of reject plates are rotatably disposed on the fixed rod and correspond to the gaps between the conveyor belts;
[0015] Several driving devices are arranged below the conveyor belt and keep the telescopic ends connected to the bottom of each reject plate through connecting rods, so as to realize the rotation and fixation of the reject plate.
[0016] Specifically, two parallel sliding bars are arranged at the end of the rejection plate close to the conveyor belt, and when the rejection plate rotates, the sliding bars can rotate into the gap between the conveyor belts.
[0017] The utility model has the following beneficial effects:
[0018] Firstly, the automatic optical inspection device sets up several parallel conveyor belts and combines the feeding mechanism to facilitate the eggs to fall one by one and evenly in the gaps between the conveyor belts for automatic transportation, so that the optical inspection irradiation device set under the conveyor belts can irradiate the eggs to detect unqualified eggs, and a rejection mechanism is movably set at the end of the conveyor belt to facilitate the diversion and transportation of qualified eggs and unqualified eggs, so as to realize the automatic rejection of unqualified eggs. The entire device has high optical inspection efficiency and can more accurately reject unqualified eggs.
[0019] Secondly, the automatic optical inspection device sets the shape of the rejection plate in the rejection mechanism so that the eggs between the conveyor belts can be smoothly transferred to the rejection plate and then diverted and transported out, thereby preventing the eggs from colliding and breaking.
[0020] Finally, the automatic optical inspection device facilitates the egg products to be evenly rolled into the gaps between the conveyor belts for transportation by reasonably setting the unloading mechanism, thereby preventing the egg products from falling onto the conveyor belts and affecting the optical inspection.

The irradiation lamp 11 is installed in the mounting slot plate 6 to keep the irradiation direction vertically upward to irradiate the conveyor belt 2 and the gap between the conveyor belts 2.
[0038] Specifically, a cover body 7 is installed on the frame body 1 just above the light inspection and irradiation device.
