Description

Technical Field

[0001] The present application relates to the technical field of automated devices, and in particular to an automatic cleaning tray device. Background Art

[0002] A pallet is a carrier for the circulation of workpieces, and its surface is provided with one or more grooves for placing workpieces.

[0003] For precision workpieces, in order to ensure the cleanliness of the workpieces, when the pallet needs to be circulated, the dust and other debris in the groove of the pallet needs to be removed first. At present, the commonly used method is to use an air gun connected to a compressed air source to blow air into the groove of the pallet to blow out the dust and other debris in the groove.

[0004] However, when using an air gun to blow away dust and other debris in the groove, the dust and other debris are easily blown into the air, causing the air quality in the working area to deteriorate, so there is room for improvement. Utility Model Content

[0005] The present application provides an automatic tray cleaning device to reduce the probability of dust flying in the air and causing poor air quality when cleaning the tray.

[0007] This automatic tray cleaning device places the tray to be cleaned on the mounting member, and then blows air into the groove of the tray through the first air jet assembly to achieve the effect of cleaning the tray. The cleaned tray is driven to the removal area by the driving member, which is conducive to reducing the possibility of dust re-contamination in the tray placement area, thereby facilitating improving the cleaning efficiency of the tray.

[0009] In this implementation, when the first air jet assembly blows air into the groove of the tray, the air extraction assembly extracts air into the placement area, and dust flying in the space of the placement area can be extracted synchronously, thereby facilitating the cleanliness of the placement area and reducing the possibility of the tray being contaminated again. In addition, the air extraction assembly can also extract air into the placement area and the removal area at the same time, so as to simultaneously extract dust and other debris leaked into the removal area, thereby facilitating the cleanliness of the removal area and further reducing the possibility of the tray being contaminated again.

[0014] In a possible implementation, the automatic cleaning tray device further includes a partition, which is connected to the sealed box and separates the loading area from the taking-out area.

[0015] In this implementation, the partition can separate the loading area and the unloading area to reduce the probability of dust flowing from the loading area to the unloading area, thereby facilitating the cleanliness of the unloading area and reducing the possibility of the cleaned tray being contaminated again.

[0016] In one possible implementation, the first jet assembly includes two groups of jet heads, which are provided with jet ports that allow gas to be ejected, and the normal directions of the jet ports of each group of jet heads are consistent; the normal directions of the jet ports of the two groups of jet heads are respectively a first direction and a second direction that are different directions, the direction in which the mounting part moves from the placement area to the removal area is a third direction, the angle between the first direction and the third direction is an acute angle, and the angle between the second direction and the third direction is an obtuse angle.

[0017] In this implementation, the two groups of nozzles are arranged to be inclined relative to each other, so that the gas ejected from the nozzles can be blown toward the root of the groove of the tray to fully clean all parts of the groove, thereby facilitating improving the cleaning effect on the tray.

[0019] In this implementation, the inclination angle of the spray head can be adjusted by rotating the connecting column to adapt to the cleaning of grooves of different shapes, thereby facilitating the improvement of the scope of application.

[0020] In one possible implementation, the sealed box body is provided with an inlet and a removal outlet, the inlet is configured for placing the tray to be cleaned in the inlet area, and the removal outlet is configured for taking out the tray from the removal area; the automatic cleaning tray device also includes a cover plate, which is configured to cover the inlet and the removal outlet.

[0021] In this implementation, the tray to be cleaned can be placed into the placement area through the placement entrance; after the tray is cleaned, the tray can be taken out through the removal exit, which has a simple structure and is easy to operate.

[0022] In one possible implementation, the insertion port and / or the removal port includes an insertion portion and a clearance portion, wherein the clearance portion is communicated with the insertion portion; the insertion portion is configured to allow the tray to pass through, and the clearance portion is configured to allow the hand holding the tray or the structural member holding the tray to pass through.

[0024] In a possible implementation, the mounting member is provided with a fixing groove for inserting one side of the tray.

[0025] In this implementation, the tray is inserted into the fixing groove, so that the tray can be connected to the mounting member, which has a simple structure and is convenient for placing or taking out the tray. BRIEF DESCRIPTION OF THE DRAWINGS
