[0021] like Figure 1 As shown, in this embodiment, the present invention includes a paddle-opening arm structure and a conveyor line. The paddle-opening arm structure is installed on the conveyor line and includes a V-shaped paddle 1, a plurality of support rods 2, and a mounting bracket 3. The plurality of support rods 2 are arranged parallel to the upper end of the mounting bracket 3. The V-shaped paddle 1 is installed on the plurality of support rods 2, and the tip of the V-shaped paddle 1 points opposite to the conveying direction of the conveyor line. The follow-up paddle-opening arm device is structurally different from previous electrical structures. It does not require electrical control. An external carrier passively opens the required arm through the V-shaped paddle 1 during conveyor belt transportation, thereby simplifying the structure and operation.

[0022] In this embodiment, the V-shaped paddle 1 includes a left paddle and a right paddle. One end of the left paddle and one end of the right paddle are connected to form the tip of the V-shaped paddle 1. The other ends of the left paddle and the other ends of the right paddle are both outwardly open. The opening angle between the left and right paddles is the deformation angle. The plurality of support rods 2 are each input from one end of the deformation angle of the V-shaped paddle 1 and output from the other end of the deformation angle of the V-shaped paddle 1. A compression spring 4 is disposed between the deformation angles of the V-shaped paddle 1 and is sleeved onto the support rods 2. The follower paddle arm opening device utilizes the compression spring 4 to generate elastic potential energy to open the external vehicle. The compression spring 4 is flexibly controlled to accommodate a variety of vehicles.

[0023] In this embodiment, a fixing nut 5 is provided on the outer side of the deformation angle of the V-shaped pick 1, the support rod 2 is a threaded rod, and the fixing nut 5 is threadedly connected to the support rod 2.

[0024] In this embodiment, the pick arm-opening structure further includes two magnets 6, which are attached to the outer sides of the deformed corner of the V-shaped pick 1. The magnets 6 attract the screws on the external carrier, allowing the pick 1 to simultaneously open the left and right arms of the external carrier.

[0025] In this embodiment, the conveyor line includes a conveying track and a conveying power mechanism; the conveying track includes a conveyor line bracket 7, a conveyor line sidewall 8 and two parallel carrier support bars 9, the two carrier support bars 9 are both arranged at the upper end of the conveyor line bracket 7, the conveyor line sidewall 8 is vertically arranged on the outside of the carrier support bar 9, the external carrier is placed on the two carrier support bars 9, the conveyor line sidewall 8 blocks the side of the external carrier, and the conveying power mechanism drives the external carrier to move on the carrier support bar 9.

[0026] In this embodiment, the conveying track also includes a carrier strip 10 arranged at the upper end of the conveying line sidewall 8. The carrier support bar 9, the conveying line sidewall 8, and the carrier strip 10 together form a concave slide, and one end of the external carrier is located in the concave slide.

[0027] In this embodiment, the conveying power mechanism includes a base plate 11 and several shift forks 13. An electric slide rail 14 is provided at the upper end of the base plate 11. A connecting plate 15 is provided on the slider of the electric slide rail 14. A conveying plate 16 is provided on the connecting plate. Several shift forks 13 are equidistantly arranged in the length direction of the conveying plate 16. The length direction of the conveying plate 16 is the same as the length direction of the carrier support bar 9. The conveying plate 16 is located between the two carrier support bars 9. The external carrier that needs to open its arms is grabbed from the previous automatic equipment station to the conveyor line. A conveyor line will have multiple external carriers. The fork 13 will move the external carrier to the position of the paddle opening arm structure. During this process, the electric slide 20 is a reciprocating mechanism. The electric slide 20 is a unidirectional movable component, which includes a movable claw 14 and a compression spring 15. When the electric slide 20 moves forward, the end face of the claw 14 will push the external carrier forward one station. When the fork 13 is reset, the compression spring 15 will be compressed, so the claw 14 will pass through the bottom of the external carrier and will not cause the external carrier to move. After the fork 13 is reset, the claw 14 has retreated to the tail of the external carrier, and the electric slide will move forward again, and the claw 14 will push the external carrier forward one station, thus realizing intermittent external carrier transportation.

[0028] In this embodiment, the conveying power mechanism further includes a plurality of brackets 12 , and the bottom of the conveying plate 16 is slidably connected to the upper ends of the plurality of brackets 12 .

[0029] In this embodiment, the fork 13 includes a claw 17, a return spring 18 and a base 19. One end of the claw 17 is hinged to the upper end of the base 19. The return spring 18 is arranged between one end of the claw 17 and the base 19. The end of the claw 17 supported by the return spring 18 is facing the conveying direction of the conveyor line.

[0030] In this embodiment, the paddle open arm structure is arranged at the input end, the middle part or the output end of the conveying line.

[0031] Working principle: The external carrier that needs to open its arms is grabbed from the previous automatic equipment station to the conveyor line, and the fork 13 will move the external carrier to the position of the paddle arm opening structure. During the movement, the magnet 6 on the paddle arm opening structure will first loosen the screws 17 on the left and right arms of the external carrier. During this process, the paddle 1 in the paddle arm opening structure a will pry the left arm 18 and right arm 19 of the external carrier apart. This is an action process.

[0032] The invention is applied to the technical field of open arm mechanisms.

[0033] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
