[0044] Specifically, the tray 1 is located on the detection pipeline 5, and the second detection component 22 can detect whether the workpiece to be detected in the tray 1 is a qualified workpiece (such as whether the appearance of the workpiece to be detected is qualified, etc.); the tray 1 is located in the buffer pipeline 6, and the second detection component 22 can detect the position of the qualified workpiece to be detected in the tray 1 and the position of the empty first accommodation groove 11 in the tray 1; the tray 1 is located in the storage pipeline 7, and the second detection component 22 can detect the position of the empty first accommodation groove 11 in the tray 1, the position of the empty second accommodation groove 41 in the storage tray 4, and the position of the replacement part. In this embodiment, the structure of the second detection component 22 is simple and the manufacturing cost is low.

[0045] In one embodiment, as Figure 1 and Figure 4 shown, the material transfer mechanism 3 includes a third support frame 31, a third moving module 32, a third lifting module 33, and a material taking piece 34. The third support member straddles the detection pipeline 5, the buffer pipeline 6, and the storage pipeline 7; it can be understood that both the second support frame 221 and the third support frame 31 are gantry structures.

[0046] The third moving module 32 is installed on the third support frame 31, the third lifting module 33 is installed on the third moving module 32, and the material taking member 34 is installed on the third lifting module 33; the third moving module 32 is used to drive the third lifting module 33 and the material taking member 34 to move along the first direction, the third lifting module 33 is used to drive the material taking member 34 to move along the third direction, and the material taking member 34 is used to pick and place the parts to be detected.

[0047] In this embodiment, the third moving module 32 can drive the third lifting module 33 and the material taking member 34 to move above the detection production line 5, and the material taking member 34 can pick up the parts to be detected from the tray 1; the third moving module 32 can drive the third lifting module 33 and the material taking member 34 to move above the buffer production line 6, and the material taking member 34 can pick up the parts to be detected from the tray 1; the third moving module 32 can drive the third lifting module 33 and the material taking member 34 to move above the storage production line 7, and the material taking member 34 can pick up the replacement parts from the storage tray 4, or store the defective parts to be detected in the second receiving groove 41 of the tray 1. In this embodiment, the structure of the material transfer mechanism 3 is compact and occupies a small space.

[0048] Another embodiment of the present invention also provides a detection method, which is applied to the above-mentioned automatic detection device, and includes: S100, the tray 1 is conveyed onto the detection production line 5, and all the first receiving grooves 11 on the tray 1 are filled with parts to be detected or replacement parts; it can be understood that each first receiving groove 11 of the tray 1 contains a part to be detected or a replacement part, so that the tray 1 is in a full-load state.

[0049] S200, the first lifting driving member 52 drives the adsorption plate 53 to move upward, the convex blocks 531 are inserted into the first receiving grooves 11 one by one, and the convex blocks 531 adsorb and fix the parts to be detected or replacement parts in the first receiving grooves 11 through the adsorption holes 532; it can be understood that the convex blocks 531 can adsorb the parts to be detected or replacement parts in the first receiving grooves 11 from the top. Since the tray 1 is in a full-load state, no vacuum leakage accident will occur between the adsorption plate 53 and the tray 1, ensuring the stability of the parts to be detected stored in the tray 1.

[0050] S300. The detection mechanism 2 sequentially detects whether the workpieces to be detected located on the detection pipeline 5 are qualified workpieces. Understandably, the tray 1 is located on the detection pipeline 5, and the second detection member 224 on the detection mechanism 2 can move in the first direction, and the tray 1 can move in the second direction in the detection pipeline 5, so that the second detection member 224 can sequentially detect the workpieces to be detected in the tray 1.

[0051] S400. After the adsorption holes 532 release the adsorption force on the workpiece to be detected or the replacement part, the material transfer mechanism 3 transfers the qualified workpieces to be detected in the detection pipeline 5 to the tray 1 located on the buffer pipeline 6. Understandably, after the adsorption holes 532 release the adsorption force, the workpiece to be detected or the replacement part is in a movable state in the first accommodation groove 11, and the material transfer mechanism 3 can transfer the qualified workpieces to be detected in the tray 1 on the detection pipeline 5 to the tray 1 on the buffer pipeline 6.

[0052] S500. The material transfer mechanism 3 transfers the unqualified workpieces to be detected in the detection pipeline 5 to the tray 1 located on the storage pipeline 7. Understandably, after the adsorption holes 532 release the adsorption force, the material transfer mechanism 3 can transfer the unqualified workpieces to be detected in the tray 1 on the detection pipeline 5 to the tray 1 on the storage pipeline 7; if there are replacement parts in the tray 1 on the detection pipeline 5, the material transfer mechanism 3 can transfer the replacement parts in the tray 1 on the detection pipeline 5 to the storage tray 4.

[0053] In the present invention, the material transfer mechanism 3 can fill the qualified workpieces to be detected or the workpieces to be detected into the empty first accommodation grooves 11, so as to ensure that the tray 1 located on the detection pipeline 5 is in a full-load state. When the adsorption plate 53 adsorbs the workpieces to be detected in the tray 1, no vacuum leakage accident will occur between the adsorption plate 53 and the tray 1, ensuring the stability of the workpieces to be detected stored in the tray 1, and thus ensuring the accuracy and stability of the detection mechanism 2 to sequentially detect the workpieces to be detected in the tray 1.

[0054] In an embodiment, as Figure 1 shown, before the tray 1 is transported to the detection pipeline 5 and all the first accommodation grooves 11 of the tray 1 are filled with workpieces to be detected or replacement parts (that is, before step S100), it further includes: After the detection mechanism 2 detects whether there are empty first accommodation grooves 11 on the tray 1, the tray 1 is transported to the detection pipeline 5. Understandably, the tray 1 is on the transfer pipeline 8, and the first detection component 21 can detect whether there are empty first accommodation grooves 11 in the tray 1 and can also detect whether the workpieces to be detected in the tray 1 are qualified.

[0055] If the material tray 1 has an empty first receiving slot 11; the material transfer mechanism 3 transfers the replacement parts in the material storage tray 4 to the empty first receiving slot 11, or transfers the good parts to be detected on the buffer line 6 to the empty first receiving slot 11, until all the first receiving slots 11 of the material tray 1 on the detection line 5 are stored with parts to be detected or replacement parts; it can be understood that after the material tray 1 is detected by the transfer line 8 to see whether it has an empty first receiving slot 11, the transfer line 8 can transport the material tray 1 on it to the detection line 5. If the material tray 1 has an empty first receiving slot 11, the material transfer mechanism preferentially removes the good parts to be detected from the buffer line 6 and places them in the empty first receiving slot 11; if the good parts to be detected in the material tray 1 on the buffer line 6 are insufficient, the material transfer mechanism removes the replacement parts from the material tray 1 on the storage line 7 and places them in the empty first receiving slot 11.

[0056] If there are replacement parts stored in the material tray 1 on the inspection line 5, after the inspection mechanism 2 inspects one by one whether the parts to be inspected on the inspection line 5 are qualified parts, it also includes: The material transfer mechanism transfers the replacement parts on the inspection line 5 to the storage tray 4; and the material transfer mechanism 3 transfers the good parts to be inspected in the inspection line 5 to the material tray 1 located on the buffer line 6, and the material transfer mechanism 3 transfers the defective parts to be inspected in the inspection line 5 to the material tray 1 located on the storage line 7.

[0057] To further explain, regardless of whether there are replacement parts in the material tray 1 on the inspection line 5, the material transfer mechanism 3 will transfer the good parts to be inspected in the inspection line 5 to the material tray 1 on the buffer line 6, and the material transfer mechanism 3 will transfer the defective parts to be inspected in the inspection line 5 to the material tray 1 on the storage line 7.
