[0041] Such as Figures 2 to 5As shown in the figure, the present utility model provides a feeding and positioning system for materials, which includes a conveying chute 20, a material taking mechanism 30, a rotating seat 40, a positioning seat 50 and a pneumatic claw 60. Among them, the conveying chute 20 is used for conveying materials; the material taking mechanism 30 has a plurality of placement holes 31 for storing materials, and the material taking mechanism 30 is docked with the conveying chute 20 so that the materials conveyed by the conveying chute 20 enter each placement hole 31 one by one; a boss 41 for placing materials is provided on the rotating seat 40, and a scanning device 42 for scanning the shape of the material is provided on one side of the rotating seat 40. The scanning device 42 is connected to the rotating seat 40 to control the material to rotate to a predetermined direction according to the scanning result; a positioning hole 51 for placing materials is provided on the positioning seat 50; the pneumatic claw 60 is movably arranged between the material taking mechanism 30, the rotating seat 40 and the positioning seat 50 to clamp the material in the placement hole 31 onto the boss 41 or into the positioning hole 51.

[0042] In the feeding and positioning system for materials of the present utility model, rough positioning of the materials is carried out through their shapes in the conveying chute 20, fine positioning is carried out through the images and shapes of the materials on the rotating seat 40, and finally terminal positioning is carried out through the shapes of the materials on the positioning seat 50. Through the above three positioning processes carried out successively, the materials are conveyed to the next working station at a predetermined angle in the positioning seat 50, realizing the assembly or installation of the materials, and solving the problems of low positioning accuracy and low production efficiency at present.

[0043] The following will detail the specific structures of each part of the feeding and positioning system for materials of the present utility model, as well as the positions and connection relationships between each part.

[0044] First of all, the feeding and positioning system for materials of the present utility model is used for feeding and positioning of materials, especially suitable for special-shaped materials with high requirements for angular accuracy. The following will be described by taking the piercing member 10 for opening the sealing film in the bottle cap as an example, but not limited thereto. As Figure 1 shown, the piercing member 10 is a plastic ring, an external thread is provided on the outer side wall of the ring, a piercing protrusion and a notch 11 are formed on the top side wall of the ring, and a positioning groove 12 is opened on the bottom side wall of the ring.

[0045] The feeding and positioning system for materials of the present utility model has a conveying chute 20. As Figure 2 shown, the conveying chute 20 has a conveying long groove extending along the conveying direction of the piercing member 10, and each piercing member 10 is located in the conveying long groove. The piercing member 10 is conveyed forward under the action of aerodynamic force in the conveying long groove. In this embodiment, the conveying long groove is a straight groove, and each piercing member 10 is conveyed forward in a straight line; in other embodiments, according to the specific requirements of the conveying direction, the conveying long groove can also be set in other shapes, such as arc-shaped. As Figure 3As shown, the cross section of the conveying slot is a rectangular groove with an open top, and there is a gap between the two sides of the puncture member 10 and the side walls of the rectangular groove to reduce the resistance of the puncture member 10 when being conveyed in the conveying slot.

[0046] Better, such as Figure 2 and Figure 3 As shown, in order to preliminarily position the puncture member 10 in the conveying groove, a guide plate 21 is provided on one side of the top of the conveying groove. The guide plate 21 is installed on the top of one side of the rectangular groove, and the guide plate 21 extends a distance toward the rectangular groove to form a pressing portion. The pressing portion can be pressed on the notch 11 of the puncture member 10 to roughly position the puncture member 10. Since the puncture member 10 can rock in the conveying groove, the setting of the pressing portion on the guide plate 21 cannot accurately limit the direction of the puncture member 10, but only preliminarily limits its conveying angle to avoid large changes in the angle of the puncture member 10 during the gas conveying process.

[0047] The material feeding and positioning system of the present invention has a material taking mechanism 30, such as Figure 2 As shown, a plurality of placement holes 31 are spaced apart along the extending direction of the retrieving mechanism 30. The placement holes 31 are used to place the piercing members 10. The placement holes 31 are provided on the side of the retrieving mechanism 30 so that one side of the placement holes 31 is open. The retrieving mechanism 30 is connected to the conveying chute 20. That is, the outlet end of the conveying slot in the conveying chute 20 is connected to the opening of the placement holes 31 in the retrieving mechanism, so that the piercing members 10 in the conveying slot can enter the placement holes 31.

[0048] Furthermore, the retrieving mechanism 30 includes a drive structure (not shown) that drives it to reciprocate so that the openings of each placement hole 31 are sequentially aligned with the outlet end of the conveyor trough. The reciprocating direction of the retrieving mechanism 30 is perpendicular to the output direction of the outlet end of the conveyor trough. Each placement hole 31 can only accommodate one piercing member 10. When a piercing member 10 enters a placement hole 31, the retrieving mechanism 30 is driven by the drive structure to move to the next station, disengaging the placement hole 31 from the retrieving mechanism 30 and simultaneously aligning the opening of the next placement hole 31 with the outlet end of the conveyor trough.

[0049] Better, such as Figure 2 and Figure 3As shown in the figure, in order to prevent the piercing member 10 in the placement hole 31 from falling, a baffle 32 capable of blocking the opening is provided on the opening side of the placement hole 31, and the baffle 32 extends along the reciprocating movement direction of the material taking mechanism 30. When the material taking mechanism 30 takes materials from a plurality of placement holes 31 in one direction, the placement hole 31 that has obtained the piercing member 10 will be disengaged from the conveying long groove. Since the baffle 32 is fixedly arranged, as the material taking mechanism 30 moves, the opening of the placement hole 31 that has obtained the piercing member 10 will be blocked by the baffle 32, thereby preventing the piercing member 10 from falling.

[0050] The feeding and positioning system for materials of the present utility model has a pneumatic claw 60. As Figure 2 shown, the pneumatic claw 60 is an inner-supporting pneumatic claw, which is arranged above the material taking mechanism 30, the rotating seat 40 and the positioning seat 50, and can move among the material taking mechanism 30, the rotating seat 40 and the positioning seat 50 to realize the transfer of the piercing member 10.

[0051] The feeding and positioning system for materials of the present utility model has a rotating seat 40. As Figure 2 and Figure 4 shown, the rotating seat 40 includes a body, and a servo motor is arranged inside the body. The output shaft of the servo motor is connected to the boss 41. The scanning device 42 has a scanning head capable of scanning the piercing member 10 placed on the boss 41. A laser displacement recognition sensor is built in the scanning head. The scanning head is arranged facing the boss 41 to obtain the notch position information of the piercing member 10. The servo motor is connected to the laser displacement recognition sensor to receive the notch position information, and drives the piercing member 10 to rotate according to the notch position information, so that the notch 11 or the positioning groove 12 of the piercing member 10 faces the predetermined direction. The above-mentioned notch position information may be the position information of the notch 11 or the positioning groove 12 on the piercing member 10.

[0052] The piercing member 10 in the placement hole 31 of the material taking mechanism 30 is placed on the boss 41 of the rotating seat 40 one by one through the pneumatic claw 60. The outer diameter of the boss 41 is slightly larger than the inner diameter of the piercing member 10, so that the piercing member 10 placed on the boss 41 forms a slight interference fit, preventing the piercing member 10 from rotating relative to the boss 41. Since the piercing member 10 is initially positioned on the conveying slideway 20, that is, the notch position (the notch 11 at the upper end or the positioning groove 12 at the lower end of the piercing member 10) on the piercing member 10 is roughly determined. When the piercing member 10 is placed on the boss 41 through the pneumatic claw 60, the notch position of the piercing member 10 faces the scanning head. The laser displacement recognition sensor recognizes the notch position information of the piercing member 10 through laser scanning and transmits a signal to the servo motor inside the body. After receiving the notch position information, the servo motor drives the boss 41 to drive the piercing member 10 to rotate, so that the notch 11 or the positioning groove 12 of the piercing member 10 faces the predetermined angle, and the precise positioning of the piercing member 10 can be completed.

[0053] The feeding and positioning system for materials of the present utility model has a positioning seat 50. As Figure 2 and Figure 5 shown, the positioning seat 50 is provided with a positioning hole 51 for placing the piercing member 10. At the bottom of the positioning hole 51, there is a positioning protrusion 52 that can be clamped into the positioning groove 12 on the piercing member 10. On the bottom wall of the positioning hole 51, there is a positioning ring. The piercing member 10 is sleeved on the positioning ring. The outer diameter of the positioning ring is larger than the inner diameter of the piercing member 10 to form a slight interference fit. The positioning protrusion 52 is arranged on the positioning ring.

[0054] After the fine positioning of the piercing member 10 is completed on the rotating seat 40, the piercing member 10 is taken out from the boss 41 by the air claw 60 and moved above the positioning seat 50, and the piercing member 10 is placed into the positioning hole 51 on the positioning seat 50. Since the piercing member 10 has been finely positioned, at this time, the angle of the positioning groove 12 on the piercing member 10 coincides with the angle of the positioning protrusion 52 in the positioning hole 51. Therefore, the piercing member 10 placed in the positioning hole 51 can achieve final positioning through the positioning protrusion 52 and the positioning groove 12. Then, the positioning seat 50 together with the piercing member 10 is conveyed to the next station to complete the assembly of the pierced bottle cap.

[0055] In the above specific embodiments, the purpose, technical solutions, and beneficial effects of the present utility model have been further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the protection scope of the present utility model.
