[0062] Furthermore, as Figure 4 、 7 shown, in this embodiment, the first positioning mechanism 4 includes: a first positioning plate 41, a first driving block 42, a first bearing 43 and a first slide rail 44;

[0063] The first positioning plate 41 is connected to the first driving block 42, and a first positioning groove 411 is provided thereon. The arc of one side of the first positioning groove 411 is larger than that of the other side. The first positioning groove 411 can be coupled with the second arc portion 832 of the bottom cover 83. Due to the different sizes of the first arc portion 831 and the second arc portion 832 and the different arc sizes of the two sides of the first positioning groove 411, when the first arc portion 831 enters the first positioning groove 411, the bottom cover 83 can rotate. When the second arc portion 832 enters the first positioning groove 411, the position of the bottom cover 83 is determined, so as to achieve the positioning of the bottom cover 83.

[0064] The first positioning plate 41 is arranged between the dial 35 and the first support disk 36;

[0065] The first driving block 42 is slidably connected to the first slide rail 44;

[0067] The first slide rail 44 is arranged on the second rotating disk 37; the first bearing 43 can drive the first driving block 42 to move along the first slide rail 44, and the first positioning plate 41 moves along with the first driving block 42.

[0068] Furthermore, as shown in Figures 1-2 Figures 4 to 6, in this embodiment, the second positioning mechanism 5 includes: a first support 51, a first driving rod 52, a first spring 53, a second bearing 54, a first pressing rod 55, a first gear 56, and a first pressing head 57;

[0069] The first support 51 is connected to the first rotating disk 33;

[0070] The first driving rod 52 is hinged to the first support 51;

[0071] The second bearing 54 is arranged at one end of the first driving rod 52 and is slidably connected to the first cam track 321 and can move along the first cam track 321;

[0072] One end of the first spring 53 is connected to the first driving rod 52, and the other end is connected to the first support 51. In the initial state, the first spring 53 is in a compressed state, so that the first bearing 43 always closely adheres to the first cam track 321;

[0073] The first pressing rod 55 is rotatably arranged at the other end of the first driving rod 52;

[0074] The first gear 56 is arranged at the upper end of the first pressing rod 55 and meshes with the output end of the first driving mechanism 6, and can drive the first pressing rod 55 to rotate;

[0075] The first pressing head 57 is arranged at the lower end of the first pressing rod 55 and can rotate along with the first pressing rod 55; the first pressing head 57 is provided with a tapered portion 571, and the tapered portion 571 can be inserted into the bottom cover 83 to contact the bottom cover 83; when the first pressing head 57 rotates, it can drive the bottom cover 83 to rotate through the frictional force between the tapered portion 571 and the bottom cover 83 until the second arc portion 832 enters the first positioning groove 411 and is limited by the first positioning groove 411, and the frictional force between the tapered portion 571 and the bottom cover 83 is not sufficient to drive the bottom cover 83 to rotate.

[0076] Furthermore, in this embodiment, a first limiting hole (not shown in the figure) is arranged on the first support 51, and the lower end of the first spring 53 is connected to the first support 51 through the first limiting hole.

[0077] Furthermore, as shown in Figure 2 Figures 4 4 to 5, in this embodiment, the first driving mechanism 6 includes: a second positioning plate 61 and a gear driving assembly 62;

[0078] The second positioning plate 61 is connected to the first fixing plate 31;

[0079] One end of the gear driving assembly 62 is connected to the second positioning plate 61 , and the other end is meshed with the first gear 56 .

[0080] Further, if Figure 2 , 4 As shown in Figure 5, in this embodiment, the gear drive assembly 62 includes: a plurality of first drive members 621, a second spring 622, and a second slide rail 623; the plurality of first drive members 621 are arranged adjacent to each other in sequence, one end of the first drive member 621 is provided with gear teeth, which can mesh with the first gear 56; the other end is connected to the second positioning plate 61 through the second spring 622; the second slide rail 623 is connected to the first fixed disk 31, and the top of the first drive member 621 is slidably connected to the first fixed disk 31 through the second slide rail 623. When the first gear 56 at the upper end of the driving rod meshes with the gear teeth on the front end of the first drive member 621 for the first time, the first drive member 621 can retreat a certain distance to make the entire meshing process smoother; the second spring 622 acts as a buffer for the first drive member 621.

[0081] Further, if Figure 5 As shown, in this embodiment, a first limiting member 624 is provided at one end of the second slide rail 623 away from the second positioning plate 61 for limiting the position of the first driving member 621 .

[0082] Further, if Figure 1 , 4 As shown, in this embodiment, a material blocking cylinder 71 and a position sensor 72 are provided at the output end of the conveyor 7; the position sensor 72 is used to detect the position of the first downward pressure rod 55, so as to determine whether the turret mechanism 2 is working. The blocking rod of the material blocking cylinder 71 is extended to block the bottom cover 83. When the cover is fed continuously normally, the material blocking cylinder 71 does not work.

[0083] Further, if Figure 1 , 7 As shown, in this embodiment, a section of arc-shaped limiting plate 38 is further provided on one side of the dial 35 , and the arc-shaped limiting plate 38 is connected to the fixing frame 1 to prevent the bottom cover 83 from being separated from the corresponding dial slot 351 .

[0084] Working principle: The turret rotates, driving the first rotating disk 33 and the second rotating disk 37 to rotate. The first bearing 43 rotates along the first cam track 321 at the lower end of the first cam disk 32, and the second bearing 54 rotates within the second cam track 341 within the second fixed disk 34. The conveyor 7 transports the bottom cover 83 into the dial groove 351 of the dial 35, and the bottom cover 83 rotates with the dial 35. Then, under the action of the first spring 53 and the first cam track 321, the second bearing 54 drives one end of the first driving rod 52 to rotate upward, and the other end of the first driving rod 52 drives the first pressing rod 55 to move downward, causing the tapered portion 571 of the first pressing head 57 to insert into the bottom cover 83. The first gear 56 meshes with the teeth of the first driving member 621, and the first pressing head 57 drives the bottom cover 83 to rotate until the second arc portion 832 enters the first positioning groove 411. The first bearing 43 drives the first positioning plate 41 to move towards the corresponding bottom cover 83 under the action of the second cam track 341, causing the bottom cover 83 to contact the first positioning groove 411 and the arc-shaped limiting plate 38. When the bottom cover 83 disengages from the arc-shaped limiting plate 38, the first positioning plate 41 pushes the bottom cover 83 onto the positioning fixture of the cover assembling machine and returns to the initial position.

[0085] As described above, with reference to Figures 1-9 the bottom cover conveying device according to the embodiment of the present invention is described, ensuring the positioning during the bottom cover conveying process, enabling the bottom cover to enter the cover assembling machine at a specific position, greatly improving the cover assembling efficiency and the qualified product rate, and reducing the cover assembling cost.
