[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0032] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0033] A stirrup stripping mechanism, such as Figure 1 The structure shown includes a stripping mechanism base 1 for fixing on the ground, and also includes:

[0034] Two mirror-symmetrically arranged peeling components, such as Figure 1 and Figure 4 In the structure shown, each peeling assembly includes a main frame 2 detachably mounted on a peeling mechanism base 1 , and two peeling units detachably mounted on the main frame 2 via a slider mounting plate 17 .

[0035] In this embodiment, the stripping unit is as follows Figure 2 and Figure 3 The stripping unit includes a telescopic arm body 6 arranged outside a slider mounting plate 17, and the slider mounting plate 17 is fixedly mounted on a Figure 1 On the main frame 2 of the mechanism shown, two linear rails 21 are installed on the corresponding sides of the telescopic arm body 6 and the slider mounting plate 17, and the slider body 20 is slidably installed on the two linear rails 21, and the slider body 20 is detachably installed on the slider mounting plate 17, that is, the telescopic arm body 6 installed with the linear rails 21 can be reciprocated by the slider body 20.

[0036] It should be noted that if Figure 1 and Figure 2 In the structure shown, a bolt-type roller needle bearing 4 is installed on the main frame 2 of the mechanism through a supporting bearing mounting seat 3, and the bolt-type roller needle bearing 4 can support the telescopic arm body 6.

[0037] Specifically, in order to realize the automatic reciprocating movement, a rack 22 is fixedly installed on the telescopic arm body 6 and between the two linear rails 21. Figure 3 In the structure shown, a transmission gear 25 is meshed and installed at the rack 22. It should be noted that because the telescopic arm body 6 has been fixed by the slider body 20, the transmission gear 25 is connected to the output shaft of the servo motor 18 installed on the slider mounting plate 17, so that the transmission gear 25 can always be meshed and transmitted with the rack 22, thereby realizing the reciprocating movement of the telescopic arm body 6; and in order to avoid derailment, as Figure 3 In the position shown, limit blocks 23 for preventing the transmission gear 25 from derailing are installed at both ends of the telescopic arm body 6.

[0038] In order to improve the accuracy of the moving position, the servo motor 18 installed on the slider mounting plate 17 is used as a power source in this embodiment. The output shaft of the servo motor 18 is coaxially connected with the transmission gear 25. At the same time, a reducer body 19 is installed on the slider mounting plate 17 through the reducer mounting plate 24. The reducer body 19 is used to be installed at the output shaft of the servo motor 18, which can maintain the stability of the movement and stop, and is conducive to improving the accuracy.

[0039] like Figure 2 and Figure 3In the structure shown, a drag chain body 5 is installed on the telescopic arm body 6, and one end of the drag chain body 5 is detachably installed on the mechanism main frame 2 through the drag chain mounting plate 16; it should be noted that a first mounting seat 7 is installed at one end of the telescopic arm body 6, and a first three-axis cylinder 8 and a second three-axis cylinder 14 are detachably installed on the first mounting seat 7, and a second mounting seat 9 is installed at the output shaft of the first three-axis cylinder 8, and a finger cylinder 10 is installed on the second mounting seat 9, and a stirrup clamp 15 is installed on the finger cylinder 10; in addition, a sensing seat 13 is installed at the output shaft of the second three-axis cylinder 14, and a mounting base block 11 is provided on the sensing seat 13, and an infrared photoelectric switch 12 is detachably installed on the mounting base block 11.

[0040] It should be noted that the working principle of the stirrup stripping mechanism of the present invention is as follows: first, before working, the stripping mechanism base 1 is fixed to the ground by expansion bolts. Figure 4 The mirror-symmetrical setting structure shown in the figure can drive the telescopic arm body 6 to move through four groups of servo motors 18, reducer body 19, transmission gear 25, and rack 22; at the same time, the second three-axis cylinder 14 can drive the sensing seat 13, the mounting base block 11, and the infrared photoelectric switch 12 to extend. When the telescopic arm body 6 continues to move, when any group of infrared photoelectric switches 12 senses the stirrups, the first three-axis cylinder 8 will drive the second mounting seat 9, the finger cylinder 10, and the stirrup clamp 15 to extend;

[0041] By using the mounting base block 11 and the stirrup clamp 15, the horizontal movement direction of one set of stirrups can be restricted. The working principles of the other three sets of telescopic arm bodies 6 are the same. After the four sets of telescopic arm bodies 6 respectively sense the stirrups and restrict their horizontal movement directions, the frontmost set of telescopic arm bodies 6 is used as a reference, and the other three sets of telescopic arm bodies 6 are all moved forward to align with it; at the current position, the four sets of finger cylinders 10 are clamped inwards, and the stirrups are clamped by using the mounting base block 11 and the stirrup clamp 15. At this time, the four sets of telescopic arm bodies 6 move forward at the same time, move to the handover station, and stop, waiting for handover;

[0042] During the handover, the four groups of finger cylinders 10 are first released, and then the first three-axis cylinder 8 drives the clamping claw cylinder mounting seat, the finger cylinder 10, and the stirrup clamping claw 15 to move in the opposite direction, and then the telescopic arm body 6 moves forward 3-5cm again. After the stirrup is out of the range of the mounting base block 11, the second three-axis cylinder 14 drives the sensing base 13, the mounting base block 11, and the infrared photoelectric switch 12 to move in the opposite direction;

[0043] After the handover is completed, the four groups of telescopic arm bodies 6 move away from the handover at the same time, and the second three-axis cylinder 14 drives the sensing seat 13, the mounting base block 11, and the infrared photoelectric switch 12 to extend and start the next cycle; in this embodiment, the support bearing mounting seat 3 and the bolt-type roller needle bearing 4 play a reinforcing role. When the telescopic arm body 6 extends forward too far, the horizontal movement of the telescopic arm body 6 can be maintained, and the load on the servo motor 18, the reducer body 19, the transmission gear 25 and the rack 22 when the front end of the telescopic arm body 6 droops, thereby avoiding damage to the telescopic arm body 6 during long-term reciprocating motion, which is beneficial to ensuring stable operation of the equipment; it should be noted that the two stripping assemblies arranged in a mirror-symmetrical manner can provide four stripping units for stripping stirrups, which is beneficial to improving the efficiency and quality of stirrup stripping, and can avoid deformation, residue or incomplete stripping of stirrups during stripping, which is beneficial to improving the qualified rate of products.

[0044] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
