It can be understood that, by the detection mechanism 3000, the automatic detection of the parts is realized, and the circular motion of the jig 3300 makes the detection process of the parts smoother.

In order to orderly convey the trays 4000, referring to fig. 5, the tray storage module further includes a supporting component 2270, the supporting component 2270 is disposed above the first horizontal conveying component 2260, the supporting component 2270 includes a supporting driving component 2271 and a supporting block 2272, the supporting block 2272 is used for supporting the trays 4000, and the supporting driving component 2271 is in driving connection with the supporting block 2272 and is used for moving the supporting block 2272 to the position below the trays 4000 or away from the position below the trays 4000.

It is understood that in the tray module for storing full-loaded trays 4000, a plurality of stacked trays 4000 are held in the corresponding holding module 2270, and when it is desired to place a full-loaded tray 4000 on the corresponding first horizontal transport module 2260, the holding driver 2271 drives the holding block 2272 away from the position under the full-loaded tray 4000, so that the full-loaded tray 4000 falls onto the first horizontal transport module 2260, and after one full-loaded tray 4000 falls onto the first horizontal transport module 2260, the holding driver 2271 drives the holding block 2272 back to the position under the next full-loaded tray 4000, so as to re-hold the stacked trays 4000. It can be understood that, through the supporting component 2270, the stacked trays 4000 can be transported to the first horizontal transport component 2260 one by one, so that the trays 4000 can be transported in order, and the transport efficiency is improved, and in addition, the utilization rate of the longitudinal space can be improved by the stacking mode of the trays 4000.

In this embodiment, in order to enable the full-loading tray 4000 to stably fall to the first horizontal transport assembly 2260, referring to fig. 5, the tray storage module further includes a first lifting assembly 2280, the first lifting assembly 2280 includes a first lifting driving member 2281 and a first lifting block 2282, the first lifting driving member 2281 is disposed below the first horizontal transport assembly 2260, and the first lifting driving member 2281 is drivingly connected to the first lifting block 2282 for moving the first lifting block 2282 in the vertical direction.

It can be understood that when a full tray 4000 needs to fall from the support assembly 2270 onto the first horizontal transport assembly 2260, first, the first lifting driving member 2281 drives the first lifting block 2282 to the bottom surface of the full tray 4000 located at the lowest position in the stacked tray 4000, the support driving member 2271 drives the support block 2272 to leave the position below the full tray 4000, the full tray 4000 falls above the first lifting block 2282, and the first lifting driving member 2281 drives the first lifting block 2282 to descend until the height of the first lifting block 2282 is lower than the upper end surface of the first horizontal transport assembly 2260, so that the full tray 4000 on the first lifting block 2282 falls onto the first horizontal transport assembly 2260. In addition, in order to stack the empty trays 4000, the above operations may be performed in a reverse direction, specifically, in the tray storage module for storing the empty trays 4000, the corresponding first lifting block 2282 moves upward to drive the empty trays 4000 on the first horizontal transfer assembly 2260 to lift, so that the lower end surfaces of the empty trays 4000 move to a height corresponding to the support block 2272, and then the first support driving part 2271 drives the support block 2272 to move below the empty trays 4000.

It will be appreciated that the cooperation of the racking assembly 2270 and the first lift assembly 2280 allows for the individual discharge of stacked full trays 4000 and the recovery stacking of empty trays 4000.

In other embodiments, it is also possible to have the distance between the holding block 2272 and the first horizontal transport assembly 2260 equal to the height of one tray 4000, so that when the holding block 2272 leaves under a full tray 4000, the stacked full tray 4000 will fall entirely to the first horizontal transport assembly 2260, the holding block 2272 is then repositioned, at which point the holding block 2272 will move under the next tray 4000 and after the full tray 4000 under it has been transported away by the first horizontal transport assembly 2260, the holding block 2272 will again hold the stack of trays 4000.

In order to improve the stability of the stacked trays, the tray storage module further comprises a support frame 2290, and the support frame 2290 is arranged around the upper portion of the support block 2272.

It will be appreciated that the support 2290 can surround the trays when the trays 4000 are stacked on the support 2272 to prevent the stacked trays 4000 from collapsing.

In order to ensure that when the material taking module 2100 takes materials, the positions of parts on the second horizontal transmission assembly 2230 are accurate, referring to fig. 6 and 7, the tray 4000 switching module further includes a first positioning assembly 2240, where the first positioning assembly 2240 is disposed on the second horizontal transmission assembly 2230 and is used for positioning the tray 4000 transferred to the second horizontal transmission assembly 2230.

In order to avoid that the first positioning assembly 2240 obstructs the tray 4000 from entering or exiting the second horizontal transfer assembly 2230, a form interval is formed between the first positioning assembly 2240 and the second horizontal transfer assembly 2230, the second horizontal transfer assembly 2230 is used for inputting or outputting the tray 4000 through the interval, the tray 4000 switching module further comprises a second lifting assembly 2250, the second lifting assembly 2250 comprises a second lifting driving part 2251 and a second lifting block 2252, the second lifting driving part 2251 is arranged below the second horizontal transfer assembly 2230, and the second lifting assembly 2250 is in driving connection with the second lifting block 2252 for driving the second lifting block 2252 to move in the vertical direction.

It can be understood that the tray 4000 can enter the second horizontal transfer assembly 2230 from the interval, when the tray 4000 moves to the second horizontal transfer assembly 2230, the second lifting driving member 2251 drives the second lifting block 2252 to ascend, the second lifting block 2252 drives the tray 4000 to move to the first positioning assembly 2240, and the first positioning assembly 2240 positions the tray 4000; after the material taking module 2100 finishes taking the parts, the second lifting block 2252 descends to return the empty tray 4000 to the second horizontal transfer assembly 2230; after the second horizontal transfer assembly 2230 is docked with the first horizontal transfer assembly 2260, the empty tray 4000 is separated from the second horizontal transfer assembly 2230 from the gap.

It can be appreciated that by providing the spacing and cooperation of the second lift assembly 2250, the tray 4000 is allowed to be transported normally within the tray 4000 switching module.

For the specific structure of first positioning component 2240, referring to fig. 7, first positioning component 2240 includes first positioning driving piece 2241, a plurality of locating pieces 2242, and locating piece 2242 encloses to close and forms the fixed position, and first positioning driving piece 2241 drives connection locating piece 2242.

It can be understood that the second lifting assembly 2250 lifts the tray 4000 to the fixed position, the first positioning driving member 2241 drives the positioning block 2242 to approach the tray 4000, and the positioning block 2242 abuts against the side surface of the tray 4000, thereby positioning the tray 4000. In addition, in this embodiment, the positioning block 2242 may be in an L-shaped structure to match with the corner end of the tray 4000 to position the tray 4000.
