In some embodiments, the loading device includes a lifter 350, a first conveying assembly 310, a flipping member 320, a first detecting member 330, and a first handling assembly 340. In the illustrated embodiment, the number of lifts 350, the first conveying assembly 310, the first detecting member 330, and the first handling assembly 340 is multiple (two in the illustrated embodiment) for improved efficiency.

The elevator 350 lifts the articles onto the first conveying assembly 310.

The first conveying assembly 310 is used to carry and convey articles.

In the illustrated embodiment, the first conveyor assembly 310 includes a first flat belt conveyor 311 and a second flat belt conveyor 312. The elevator 350 lifts the articles onto the first flat belt conveyor 311. The first flat belt conveyor 311 and the second flat belt conveyor 312 sequentially carry and convey articles. Specifically, the first detecting element 330 detects the article on the first flat belt conveyor 311, and the first conveying assembly 340 conveys the article on the first flat belt conveyor 311 to the second flat belt conveyor 312 according to the detection result. As described in detail below.

After the articles are lifted by the elevator 350 onto the first conveying assembly 310, there may be a stacking situation for which the loading apparatus further comprises a barrier 360. The barrier 360 is disposed above the first conveying assembly 310, and the gap between the barrier and the first conveying assembly 310 is greater than the height of the article and less than twice the height of the article. The blocking member 360 may be a brush to avoid damaging the article.

In some embodiments, the loading device further comprises a magazine 391. The magazine 391 is for receiving articles that are not timely carried away by the first carrier 340. Specifically, the magazine 391 is disposed at the end of the conveying path of the first flat belt conveyor 311, and is located below the first flat belt conveyor 311.

The start end 322 extends obliquely downward to one side with respect to the horizontal plane.

The guide passage 321 is upwardly opened within a predetermined range of the start end 322 in the extending direction. Specifically, the guide channel 321 opens upward within the H1 dimension of the start end 322 in the first direction D1, forming an open area P. When the object level is in the free fall of the open area P, the object can enter the guide channel 321 unobstructed.

The end 323 extends obliquely downward toward the other side, relative to the horizontal plane.

The distal end 323 is open to the extension direction and is located above the first conveying assembly 310. The articles can be deposited onto the first conveyor assembly 310 after sliding off the end 323, and in particular, in the illustrated embodiment, the articles can be deposited onto the second flat belt conveyor 312 after sliding off the end 323.

Referring to fig. 9, fig. 9 is a schematic view illustrating a process of sliding an article along the guide channel 321 of the flipping unit 320 shown in fig. 7.

The direction of extension of the start end 322 and the end 323 of the guide channel 321 is set as described above so that the article can be turned from bottom up to bottom down.

In some embodiments, the guide channel 321 extends from a start end 322 to a finish end 323, with a deflection angle of less than 180 °. Since the article slides down the guide path 321 by gravity, the smaller the deflection angle of the extending direction is, the lower the probability of the article getting stuck in the guide path 321 can be.

Specifically, in the embodiment shown in fig. 8, the starting end 322 extends along the first direction D1, and the angle A1 between the first direction D1 and the horizontal plane is 45 °. The tip 323 extends in a fourth direction D4, the fourth direction D4 being at an angle A4 of 22 ° to the horizontal. The guide channel 321 extends from a start end 322 to a finish end 323 at a deflection angle of 113 °.

In some embodiments, the feeding device is further provided with a detecting member (not shown) for detecting whether the article is jammed in the guiding channel 321.

In some embodiments, guide channel 321 extends a predetermined distance along gravitational direction D0 at least partially between start end 322 and end 323. The portion of the guide passage 321 extending in the gravitational direction D0 is a vertical section. The portion from the start end 322 to the vertical section extends in a constant direction. The portion of the vertical section to the tip 323 extends in at least two directions in sequence. Specifically, in the embodiment shown in fig. 8, the guide passage 321 extends in the first direction D1, the second direction D2, the third direction D3, and the fourth direction D4 in this order. The angle A1 between the first direction D1 and the horizontal plane is 45 °. The second direction D2 is the gravitational direction D0. The angle A3 between the third direction D3 and the horizontal plane is 63 °. The tip 323 extends in a fourth direction D4. The fourth direction D4 forms an angle A4 of 22 ° with the horizontal plane.

The first detecting member 330 is used for detecting whether the article is bottom-up. Specifically, the first detecting member 330 is for detecting whether the article on the downstream side of the blocking member 360 is bottom-up.

The first detecting member 330 is disposed corresponding to the conveying path of the first conveying assembly 310. Specifically, in the illustrated embodiment, the first detecting member 330 is disposed on the first flat belt conveyor 311 and is located directly above the first flat belt conveyor 311.

In some embodiments, the first detection member 330 may be a visual detection device, for example, including a CCD camera. In other embodiments, other means of detection may be employed, such as by a sensor to detect whether the article is bottom-up.

In some embodiments, the first sensing element 330 is electrically connected to a controller (not shown). The controller is also electrically connected to the first handling assembly 340. The controller controls the first carrying assembly 340 to operate according to the detection result of the first detecting member 330.

The first carrying assembly 340 is configured to carry and release an article with an upward bottom to a position directly above the opening of the start end 322 of the guide channel 321, so that the article with the upward bottom falls into the guide channel 321, and further, the article with the upward bottom slides along the guide channel 321 under the action of self gravity, and slides out from the opening of the end 323 of the guide channel 321 after being turned over to the downward bottom in the sliding process, and falls onto the first conveying assembly 310.

Referring to fig. 10, fig. 10 is a schematic three-dimensional structure of a first handling assembly 340 in the loading apparatus shown in fig. 3.

Specifically, the first handling assembly 340 includes a base 341, a four-axis robot 342, a connector 343, two blade cylinders 344, and a sponge suction cup 345. The four-axis robot 342 is provided on the base 341. The connecting piece 343 is provided at the driving end of the four-axis robot 342. Two blade cylinders 344 are provided on the connector 343. The sponge sucker 345 is provided at the driving end of the blade cylinder 344. The four-axis robot 342 drives the blade cylinder 344 to a specified coordinate position. The blade cylinder 344 extends out to drive the sponge sucker 345 to suck the article. The sponge sucker 345 can stably suck the article without worrying about vacuum damage caused by the concave-convex structure of the surface of the article. Two blade cylinders 344 are arranged at the same time, so that the four-axis robot 342 can absorb two articles in a single cycle, and the efficiency is improved.

In the illustrated embodiment, if the first detector 330 detects that the first flat belt conveyor 311 is bottom down, the controller controls the first transfer assembly 340 to transfer the bottom down article onto the second flat belt conveyor. During this process, the orientation of the article is unchanged. If the first detecting member 330 detects that the bottom of the article on the first flat belt conveyor 311 is upward, the controller controls the first carrying assembly 340 to carry the article with the bottom upward to a position just above the opening of the start end 322 of the guide channel 321 and release the article, so that the article falls on the second flat belt conveyor 312 after being guided by the guide channel 321. During this process the article is turned 180 °, i.e. the article is turned bottom down. In the illustrated embodiment, the articles on the first flat belt conveyor 311 may have both a bottom up and a bottom down orientation, but the articles on the second flat belt conveyor 312 have only one bottom down orientation.

The limiting parts are in one-to-one correspondence with the bearing areas, and each limiting part is arranged in the corresponding bearing area and is used for being matched with the article to limit the position of the article in the process that the article falls in the corresponding bearing area. The limiting portion is, for example, a groove on the top surface of the carrying table 370, the shape of the groove is matched with the shape and size of the bottom of the article, and when the article is placed in the groove, the position of the article is limited. Alternatively, the limiting portion is a protruding column protruding from the top surface of the carrying platform 370, and the protruding column is matched with the positioning hole on the article to limit the position of the article.

The second carrying assembly 380 is used for carrying the articles on the downstream sides of the plurality of flipping members 320 to the plurality of carrying areas of the carrying table 370, and allowing each article to fall on one carrying area, so that the plurality of articles can be arranged on the carrying table 370 according to a predetermined rule. The second carrying assembly 380 is further configured to carry the plurality of articles onto the carrier 200 after the plurality of articles are placed in the plurality of carrying areas. After the plurality of articles are arranged on the carrying table 370 according to the predetermined rule, the second carrying assembly 380 carries the plurality of articles onto the carrier 200 simultaneously.

In some embodiments, the loading device further comprises a plurality of second detecting members (not identified in the figures).

Referring to fig. 15, fig. 15 is a schematic three-dimensional structure of a third detecting member 700 in the kit assembling apparatus shown in fig. 3.

To perform the function of the third sensing element 700, in some embodiments, the third sensing element 700 includes a mounting base 740, a moveable element 780, a sensor 720, and a second driver 790.

The movable member 780 is movably disposed on the mounting base 740 and can move relative to the mounting base 740 along a predetermined direction. Specifically, in the illustrated embodiment, the movable member 780 is slidably engaged with the mounting base 740 along the gravitational direction D0 and is movable relative to the mounting base 740 along the gravitational direction D0 or a direction opposite thereto. The predetermined direction is the reverse of the gravitational direction D0.

If the two ends of the bottom case 1 in the length direction are not inverted, the movable member 780 is located at the first position Q1 corresponding to the end of the bottom case 1. If the two ends of the bottom case 1 in the length direction are reversed, the movable member 780 faces one end of the bottom case 1 to correspond to the second position Q2. Since the first position Q1 and the second position Q2 are different in height, if the two ends of the bottom case 1 in the length direction are reversed, the movable member 780 moves a greater distance along the predetermined direction relative to the mounting seat 740, and thus triggers the sensor 720.
