A feed trough 73 and a blanking trough 71 are provided on the support 7 at intervals; the support 7 located at the end of the feed trough 73 is connected to the feed plate 5, and the feed plate 5 is provided with a material channel 51 connected to the feed trough 73; the support 7 located below the blanking trough 71 is connected to the blanking cylinder 2, and a deflection mechanism 8 is installed on the blanking cylinder 2; an end discrimination mechanism 3 is also installed on the support 7, and the end discrimination mechanism 3 and the feed plate 5 are arranged at the opposite ends of the support 7; and a material dividing mechanism 6 is also included.
[0037] During use, the pen barrel 10 is horizontally conveyed to the inner side of the feed trough 73 of the support 7 via the feed channel 51 of the feed plate 5. The end discrimination mechanism 3 performs end discrimination detection on the pen barrel 10 on the support 7 to determine the yaw direction of the yaw mechanism 8. The material distribution mechanism 6 moves the pen barrel 10 to above the blanking trough 71. The pen barrel 10 yaws and falls in the blanking cylinder 2 so that the preset end faces downward, thereby effectively ensuring that the ends of the pen barrel 10 are in the same direction.
[0038] In this embodiment, the end of the feeding plate 5 is connected to the discharge port of the vibration plate and the linear vibrator, and the pen barrels 10 are automatically and orderly arranged in the material channel 51 through the vibration plate and the linear vibrator.
[0039] The two side brackets 1 located above the support 7 are jointly mounted with an upper plate 4 , and the material distribution mechanism 6 is mounted on the bottom surface of the upper plate 4 , with the upper plate 4 constituting the structural support of the material distribution mechanism 6 .
[0040] A material receiving groove 621 is provided on the bottom surface of the material dividing plate 62 in the material dividing mechanism 6 . The material receiving groove 621 is aligned with one of the material feeding groove 73 and the material discharge groove 71 . The pen barrel 10 is passed through the material receiving groove 621 along the length direction.
[0041] During use, the pen body 10 extends into the material receiving groove 621 of the dividing plate 62 through the feeding groove 73. As the dividing plate 62 moves, the pen body 10 is pushed by the dividing plate 62 to move to the discharge groove 71 to achieve material separation.
[0042] A movable long slot 74 is provided on the support 7, and the length direction of the movable long slot 74 is consistent with the moving direction of the dividing plate 62, and the dividing plate 62 moves inside the movable long slot 74; the feeding slot 73 is vertically penetrated and opened on one side wall of the movable long slot 74, and the width dimension of the movable long slot 74 is not less than the length dimension of the pen body tube 10; as the dividing plate 62 moves and pushes, the pen body tube 10 moves a preset distance in the length direction of the movable long slot 74.
[0043] The structure of the material distribution mechanism 6 is as follows: it includes a material distribution cylinder 61 and a material distribution guide rail 63 arranged parallel to each other or along the same straight line. The output part of the material distribution cylinder 61 is installed with a material distribution plate 62, and the material distribution plate 62 is slidably assembled with the material distribution guide rail 63.
[0044] like Figure 4 As shown, the structure of the end discrimination mechanism 3 is as follows: it includes a support plate 33 installed on the end surface of the support 7, and an upper linear driving force 31 and a lower linear driving force 35 are installed at intervals on the same side of the support plate 33. The output part of the upper linear driving force 31 is installed with an upper pressing piece 32, and the output part of the lower linear driving force 35 is installed with a lower pressing piece 34. The upper pressing piece 32 and the lower pressing piece 34 are arranged opposite to each other in the upper and lower directions and are respectively provided with an inwardly concave arc structure 301 at the opposite ends; as shown Figure 5 As shown, a cavity 302 communicating with an external air source is provided inside the upper pressing piece 32 and the lower pressing piece 34 , and the cavity 302 has an opening in the middle of the concave arc structure 301 .
[0045] In this embodiment, when in use, the upper linear driving force 31 and the lower linear driving force 35 in the end determination mechanism 3 move toward each other, driving the upper pressing piece 32 to be press-fitted on the upper circumference of the pen barrel 10, and the lower pressing piece 34 to be press-fitted on the lower circumference of the pen barrel 10, in combination with a hole opened on the wall surface of one end of the pen barrel 10; if there is a hole at the end of the pen barrel 10 at the end determination mechanism 3, at least one of the upper pressing piece 32 or the lower pressing piece 34 will not be able to maintain pressure after being connected to the air source; if there is no hole at the end of the pen barrel 10 at the end determination mechanism 3, both the upper pressing piece 32 and the lower pressing piece 34 will maintain pressure after being connected to the air source, thereby effectively and reliably detecting the direction of the end of the pen barrel 10.
[0046] The concave arc structures 301 at the opposite ends of the upper pressing piece 32 and the lower pressing piece 34 are arranged around the circumference of the pen body tube 10, and thus are arranged around the outer wall surface of the pen body tube 10 from the same circumference to realize the determination of the hole position on the pen body tube 10.
[0047] The support 7 is provided with a through hole 72 for the downward pressing member 34 to pass upward. The through hole 72 corresponds to the feed slot 73 one by one and is located on the same straight line.

[0050] In this embodiment, the swinging direction of the pen body tube 10 when falling is guided by the deflection of the swinging member 81 located in the blanking cylinder 2, thereby effectively ensuring that the ends of the pen body tube 10 face in the same direction.
[0051] The usage of this utility model is:
[0052] The pen body tube 10 arranged horizontally in the material channel 51 of the feeding plate 5 enters the movable long groove 74 of the support 7 through the feeding groove 73, and the pen body tube 10 passes through the material receiving groove 621 located in the dividing plate 62; the end discrimination mechanism 3 works, the upper linear driving force 31 and the lower linear driving force 35 move toward each other, driving the upper pressing piece 32 and the lower pressing piece 34 to fit toward each other at the same circumference of the end of the pen body tube 10, and the air source connected to the cavity 302 works, through the inside of the cavity 302 The direction of the end of the pen body tube 10 is determined by the pressure maintenance condition; then the swing driving power 82 in the deflection mechanism 8 drives the swing member 81 to deflect, and the distribution cylinder 61 in the distribution mechanism 6 drives the distribution plate 62 to move, and the distribution plate 62 distributes the pen body tube 10 to the top of the blanking chute 71; the pen body tube 10 falls into the blanking cylinder 2, and the pen body tube 10 is guided by the swing member 81 and deflects in the vertical plane, so that the pen body tube 10 falls in a vertical state with the preset end facing downward.
[0053] The utility model effectively ensures that the ends of the pen body tubes face in the same direction, realizes accurate and smooth automatic loading, effectively guarantees subsequent automatic assembly, and has good practicality.
