[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] like Figure 1As shown, an automatic transfer module for a tray 4 of an appearance inspection device comprises a frame 1, on which a tray loading and unloading mechanism 2 and a tray transfer mechanism 3 are arranged, the tray loading and unloading mechanism 2 comprises a loading unit 21 and a unloading unit 22 of the same structure and arranged side by side, the loading unit 21 and the unloading unit 22 both comprise a roller conveyor line 23 and a tray lifting module 24 arranged at the end of the roller conveyor line 23, the roller conveyor line 23 is provided with a plurality of blocking cylinders 25, each of which is respectively connected to a block 26 capable of blocking the tray, the tray lifting module 24 comprises a lifting frame 27, on which a lifting linear module 28 is arranged, and the lifting linear module 28 is connected to a load-bearing lifting plate 29 capable of carrying the tray; the tray transfer mechanism 3 comprises a pair of slide rails 31 arranged on the frame 1, the pair of slide rails 31 are connected to a tray fixing stand 32 through a slider, the tray The tray fixing stand 32 is provided with a tray loading hole 33 and a tray unloading hole 34. The tray loading hole 33 is located directly above the tray lifting module 24 of the loading unit 21, and the tray unloading hole 34 is located directly above the tray lifting module 24 of the unloading unit 22. The tray fixing stand 32 is provided with fixed cylinders 35 on four sides of the tray loading hole 33 and the tray unloading hole 34, respectively. The fixed cylinders 35 are connected to abutment plates 36 that can abut against the tray. The frame 1 is provided with a tray transfer linear module 37 which can drive the fixed platform to move along the pair of slide rails 31. The tray transfer linear module 37 can drive the tray loading hole 33 to move to just above the tray lifting module 24 of the unloading unit 22. The tray fixed platform 32 is provided with a plurality of upper photoelectric sensors 38 at the tray loading hole 33 and the tray unloading hole 34 respectively, which can detect whether there is a tray in the tray loading hole 33 and the tray unloading hole 34.

[0015] The present scheme is an automatic transfer module for the tray 4 of an appearance inspection equipment. The tray loaded with materials is manually placed into the loading unit 21 of the tray loading and unloading mechanism 2, that is, the roller conveyor line 23 of the loading unit 21. If the equipment is already running and the previously placed tray is still on the load-bearing lifting plate 29, then the blocking cylinder 25 on the roller conveyor line 23 drives the block 26 to rise to block the newly placed tray. When the previous tray is used up, the blocking cylinder 25 drives the block 26 to descend, and the lifting linear module 28 drives the load-bearing lifting plate 29 to descend to the lowest point. At this time, the roller conveyor line 23 drives the newly placed tray to move to the load-bearing lifting plate 29, and then the lifting linear module 28 drives the load-bearing lifting plate 29 and the tray to rise to the tray transfer mechanism 3. The conveying direction of the roller conveyor line 23 of the unloading unit 22 is opposite to that of the roller conveyor line 23 of the loading unit 21. After a certain amount of material trays are received on the carrying conveying plate of the unloading unit 22, the carrying lifting plate 29 drives the material trays to descend, and the roller conveyor line 23 drives the material trays to move out. At this time, the blocking cylinder 25 of the unloading unit 22 drives the block 26 to rise and block the material trays until the material trays are taken away manually.

[0016] The tray transfer mechanism 3 is used to receive trays full of materials to be tested and to transfer empty trays. The tray loading hole 33 is located directly above the tray lifting module 24 of the loading unit 21. The full tray is lifted by the load-bearing lifting plate 29 of the loading unit 21. After the top tray is detected by the upper photoelectric sensor 38, the fixed cylinder 35 drives the abutment plate 36 to abut and fix the top A tray. After the A tray is fixed, the three-axis material transfer mechanism can take materials normally. When the material in the A tray is taken out, the transfer action begins. First, the fixed cylinder 35 located at the tray unloading hole 34 retracts the abutment plate 36, then the load-bearing lifting plate 29 of the unloading unit 22 drives the B tray at the tray unloading hole 34 to descend, and then the tray transfer linear module 37 drives the entire tray fixing stand 32 and the A tray to move along the slide rail 31, and the tray transfer linear module 37 can drive the A tray to move to just above the tray lifting module 24 of the unloading unit 22, then the fixed cylinder 35 at the tray loading hole 33 retracts the abutment plate 36, and the A tray falls onto the B tray, and then the tray transfer linear module 37 can drive the tray fixing frame to reset, and after the upper photoelectric sensor 38 on the tray fixing frame detects the A tray, the fixed cylinder 35 at the tray unloading hole 34 drives the abutment plate 36 to fix the A tray, and then the loading unit 21 drives the C tray to rise to the tray loading hole 33 again, and the fixing method is the same as that of the A tray, and the tray turnover is realized in this reciprocating manner.

[0017] Preferably, a baffle 210 is fixedly provided at the entrance of the roller conveyor line 23. The baffle 210 can prevent the stacked trays 4 from escaping from the roller conveyor line 23.

[0018] Preferably, the abutment plate 36 is in an L-shape capable of supporting the tray 4. This arrangement enables the abutment plate 36 to support the tray 4, resulting in a better fixing effect.

[0019] Preferably, the roller conveyor line 23 is provided with a lower photoelectric sensor 211 capable of detecting the tray 4. The lower photoelectric sensor 211 can stop the cylinder 25 from operating in time when the tray is manually placed on the roller conveyor line 23.

[0020] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
