[0028] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0029] Embodiment 1: The structure of the conveying mechanism provided by the embodiment of the present utility model is as Figures 1 to 3 shown. It includes a front conveying unit 2, a transfer unit 20, a rear conveying unit 3, and a grasping and loading unit 6 in sequence along the front-back direction. A baffle plate 7 is provided at the rear end of the front conveying unit 2. A number of temporary storage positions 4 and a turning position 5 are provided at intervals along the front-back direction below the transfer unit. By setting the turning position 5 at the transfer unit 20 in this conveying mechanism, when the product passes through the turning position 5 during the conveying process, the turning position 5 controls the product to adjust its direction, so as to better meet the production needs. When the conveying mechanism is actually used, the front conveying unit 2 receives the products provided by the previous station at the front end and conveys them backward until they are blocked by the baffle plate 7. The transfer unit 20 takes the products one by one from the baffle plate 7 and places them on the temporary storage positions 4 and the turning position 5 in sequence, and at the same time takes the products on the temporary storage positions 4 / turning position 5 and places them on the rear conveying unit 3. The rear conveying unit 3 conveys the products backward, and finally the grasping and loading unit 6 takes the products and places them on the material tray (the material tray is provided by the material tray conveying mechanism 8). The front-back order of the turning position 5 and the temporary storage positions 4 and the number of the temporary storage positions 4 can be flexibly set. For example, the number of the temporary storage positions 4 can be set to two, three, or four.

[0030] Further optimize the structure of the transfer unit 20. Specifically, refer to Figures 4 to 6As shown in the figure, the transfer unit 20 includes a mechanism frame 21, a driving unit 22, a driving arm 23, a cross frame 24, a first suction nozzle 26 and a driving shaft 27. The mechanism frame 21 is fixed on the machine table 1. The driving unit 22 is fixed on the mechanism frame 21. A vertical guide rail 28 is fixed on the mechanism frame 21. A slider 29 is slidably provided on the vertical guide rail 28 in the up and down direction. A horizontal guide rail 210 is fixed on the cross frame 24. The horizontal guide rail 210 forms a front and rear sliding fit with the slider 29. A plurality of first suction nozzles 26 are installed on the cross frame 24 at intervals in the front and rear directions. The first suction nozzles 26 are connected to a suction pipeline through air pipes. When the first suction nozzles 26 inhale air, they adsorb the products. The cross frame 24 is fixedly connected to the driving shaft 27. A U-shaped sliding hole 211 is provided on the front surface of the mechanism frame 21. The driving arm 23 is driven by the driving unit 22 to rotate forward and backward at a specific angle in the vertical plane. A long strip-shaped driving hole 231 is provided on the driving arm 23. The driving shaft 27 extends into the driving hole 231 and the sliding hole 211. When the driving arm 23 rotates, it drives the driving shaft 27 to move along the sliding hole 211, thereby driving the cross frame 24 to move up and down and back and forth at the same time. Through the cooperation of the vertical guide rail 28, the slider 29 and the horizontal guide rail 210, the cross frame 24 is restricted to move in the up and down and front and rear directions. During operation, the driving unit 22 drives the driving arm 23 to rotate. When rotating, the driving hole 231 on it pushes the driving shaft 27 to rise first and then fall in the up and down direction along the sliding hole 211, and at the same time, a displacement occurs in the front and rear directions. During this process, the cross frame 24 and the first suction nozzles 26 fixed to it are driven to displace, so as to transfer the products from front to back. By driving the driving arm 23 to continuously rotate forward and backward by the driving unit 22, the purpose of backwardly transferring the products is achieved.

[0031] See Figure 6 As shown in the figure, in order to reduce the friction force between the driving shaft 27 and the driving hole 231 and the sliding hole 211, a freely rotatable first roller 271 and a second roller 272 are sleeved on the driving shaft 27. The outer peripheral wall of the first roller 271 contacts the side wall of the driving hole 231, and the outer peripheral wall of the second roller 272 contacts the side wall of the sliding hole 211. Thus, the first roller 271 can roll along the side wall of the driving hole 231, and the second roller 272 can roll along the side wall of the sliding hole 211. The friction force is small and the movement is smooth.

[0032] Further, set the specific angle to be 120 degrees to 180 degrees, specifically, it can be set to 120 degrees, 150 degrees or 180 degrees, and preferably set to 180 degrees; position sensors 212 are respectively provided at the front and rear ends and the upper end positions of the sliding hole 211 on the mechanism frame 21, a trigger member 270 is provided on the drive shaft 27, and the position sensors 212 are located on the movement track of the trigger member 270, so that when the drive shaft 27 moves along the sliding hole 211 to the corresponding position, the position sensors 212 at the corresponding positions are triggered by the trigger member 270, and the position signals are transmitted to the control system of the automatic loading machine.

[0033] To improve the structural stability, as Figure 1 shown, the number of vertical guide rails 28 is set to two, and the two vertical guide rails 28 are respectively fixed on both sides of the front part of the mechanism frame 21, and the two vertical guide rails 28 provide effective guiding and limiting functions for the slider 29; in this embodiment, the driving unit 22 is set as a motor, and in actual operation, the driving unit 22 can also be set as a rotary cylinder.

[0034] As Figure 4 shown, a connecting plate 25 is fixed on the upper part of the cross frame 24, and the upper end of the connecting plate 25 is fixedly connected to the drive shaft 27. Such a setting can reduce the height position of the cross frame 24 and avoid position interference.

[0035] As Figure 2 shown, the temporary storage position 4 includes a base A41 fixed on the machine table 1 and a tray A42 fixed on the base A41. A product cavity A43 for placing products is provided on the tray A42, and the suction nozzle 26 places the products in the product cavity A43 for temporary storage to meet the intermittent transfer needs of the products.

[0036] As Figure 3 shown, the turning position 5 includes a base B51 fixed on the machine table 1, a rotary steering cylinder 52 fixed on the base B51, and a tray B53 driven by the rotary steering cylinder 52. A product cavity B54 for placing products is provided on the tray B53, and the rotary steering cylinder 52 drives the tray B53 to rotate a certain angle to realize the commutation of the products.

[0037] In this embodiment, the front transfer unit 2 and the rear transfer unit 3 are set as belt transfer mechanisms powered by a motor; the belt transfer mechanism includes a driving wheel and a driven wheel arranged opposite to each other and at intervals, and a transfer belt connecting the driving wheel and the driven wheel. The driving wheel is driven by the motor to rotate and drives the transfer belt to drive.

[0038] As Figure 1As shown in the figure, the grasping and loading unit 6 includes a mounting plate 61 arranged in the front-rear direction, a plurality of second suction nozzles 62 fixedly spaced in the front-rear direction on the mounting plate 61, and a two-dimensional driving mechanism 63 for driving the mounting plate 61 to move in the up-down direction and the front-rear direction; the two-dimensional driving mechanism 63 drives the mounting plate 61 and the second suction nozzles 62 thereon to move, so as to pick up the products at the rear end of the rear conveying unit 3 and place them on the material tray; the second suction nozzles 62 are connected to the suction pipeline through air pipes, and the products are tightly sucked when the second suction nozzles 62 suck air. The above two-dimensional driving mechanism 63 is composed of a first driving mechanism arranged in the front-rear direction and a second driving mechanism arranged in the up-down direction. The first driving mechanism and the second driving mechanism can adopt a lead screw driving mechanism or a cylinder driving mechanism, and their structures are prior arts and will not be elaborated in this embodiment.
