[0025] Generally in artificial loading, in order to improve the work efficiency, the tray full of parts is stacked and placed on the tray rack, and then conveyed to the loading station, so the support column 14 is arranged at the four corners of the tray 13, the limit hole is arranged at the corresponding position of the lower part of the tray and the support column 14, and the recess corresponding to the clamping jaw is arranged at both sides of the tray 13, so that when the plurality of trays are stacked, the support column 14 of the next layer is inserted into the limit hole of the previous layer, preventing the previous layer of tray from directly pressing on the parts of the next layer of tray, and ensuring the stability of the stacking.

[0026] When the plurality of trays are stacked, the height of each stacking is different, which leads to that the loading robot can realize different height picking, and this requirement will increase the cost of the loading device, so the lifting device capable of lifting can be arranged at the loading position, so that the same height loading is realized through the adjustment of the lifting device, specifically, the middle part of the tray rack 2 is hollow, the inner wall of the hollow part is provided with a boss, when the plurality of trays are placed on the tray rack, the lowermost tray is placed on the boss in the hollow part, the hollow shape is the same as the outer shape of the tray, which can effectively prevent the tray from shaking on the tray rack, the lifting device is arranged on the machine table 1, specifically including the support plate 10, the guide column 11 and the through type lead screw motor 12, the support plate 10 is arranged on the upper part of the machine table 1, the through type lead screw motor 12 is arranged on the lower part of the machine table 1, the lead screw of the through type lead screw motor 12 penetrates the machine table 1 and is connected with the lower part of the support plate 10 through the guide column 11, the support plate 10 is lifted by the through type lead screw motor 12, and when the support plate 10 is lifted, the support plate 10 is lifted from the hollow part in the middle of the tray rack 2, when the stacking height is lower than the preset height of the loading, the bottom through type lead screw motor 12 lifts the tray to a high position, when the stacking height is higher than the preset height of the loading, the bottom through type lead screw motor 12 drives the tray to shrink and lower, at the same time, when the holding fork is used to convey an empty tray to the material receiving position, the loading position must be lower than the preset height, at this time, it also needs to be lifted, based on the same principle, the corresponding lifting device is arranged at the material receiving position, which is used to adjust the height of the other tray rack.

[0027] The specific working principle is as follows: when feeding, the operator first adjusts the supporting plate 10 at the feeding position to the lowest position, transports the tray rack 2 to a position convenient for feeding through the second rodless cylinder 9, and then places the stacked tray on the tray rack. At this time, it is necessary to ensure that the height of the uppermost layer is lower than the preset height corresponding to the feeding mechanical arm at the feeding position. When the second rodless cylinder 9 transports the stacked tray to the feeding position, the lifting device below the feeding position lifts the tray to the preset height. At this time, the feeding to the processing equipment is completed. At the same time, an empty tray needs to be placed at the discharging position, and the lifting device at the discharging position is used to lift the empty tray to the specified receiving height. At this time, normal feeding and discharging can be carried out. When all the parts on a tray at the feeding position are completely fed, the empty tray is transported to the discharging position by the first rodless cylinder 5 and the clamp 6, and is stacked with the tray at the discharging position. The subsequent receiving is placed on the tray, and the tray at the discharging position is lowered by the lifting device, and the tray at the feeding position is lifted by the corresponding lifting device. When the tray at the receiving position cannot be lowered in height due to continuous stacking, the tray on the tray rack 2 is transported to a position convenient for taking off by the second rodless cylinder 9 at the receiving position, and the tray is taken off.
