[0001] The utility model relates to a key ring device, in particular to a key ring machine with an automatic positioning structure. Background Art
[0002] Generally, padlocks are equipped with several keys. In order to better store the several keys of the same padlock in a unified manner, the manufacturer will string these keys together. The traditional key stringing machine is similar to the key stringing machine disclosed in ZL201220369557.9. It realizes the stacking of multiple keys by cooperating with the key drop groove and the key stringing groove; and then cooperates with the lead mechanism to pass the wire through the stringing holes at the handle end of multiple stacked keys during the process of bending the wire into a ring, so as to realize the key stringing operation. However, in this type of key stringing machine, in order to allow the key to stably fall into the key stringing groove after being guided by the key drop groove, the key stringing groove will be slightly larger than the key, which will cause the keys in the key stringing groove to be stacked unevenly, and the wire will easily hit the key during the bending process, making it impossible to string the keys together.
[0003] Therefore, the existing key ring machine has the problem of poor neatness when ringing keys. Utility Model Content

[0023] The bottom of the placement groove 9 is a support plate 14 horizontally slidably connected to the placement block 7, and a string ring groove 15 is provided on the support plate 14 at the open position corresponding to the placement groove 9; a No. 3 telescopic cylinder 16 facing the placement groove 9 is connected between the support plate 14 and the placement block 7; the wire bending mechanism includes a wire guide driving wheel 17 rotatably connected to the wire guide mounting block 2, and a motor 25 is connected to the wire guide driving wheel 17, and a wire guide driven wheel 18 rotatably connected to the wire guide mounting block 2 is closely arranged on one side of the wire guide driving wheel 17; a wire guide fixed on the wire guide mounting block 2 is arranged above the position where the wire guide driven wheel 18 and the wire guide driving wheel 17 are closely attached Block 19, a vertical wire guide hole 20 is provided in the wire guide block 19; a mounting hole 21 is provided on the wire guide mounting block 2 at a position corresponding to the top of the wire guide block 19, and a bending guide block 22 is inserted in the mounting hole 21; a bending guide groove 23 is provided on the bending guide block 22, one end of the bending guide groove 23 is connected to the top of the wire guide hole 20, and the other end of the bending guide groove 23 is a wire outlet; the bending guide block 22 is provided with a plurality of bending guide grooves 23 distributed along the axial direction of the bending guide block 22; the wire guide mounting block 2 is connected to a stabilizing block 24 which is clamped and sleeved on the top of the wire guide block 19, and the top surface of the stabilizing block 24 is tightly arranged on the bottom surface of the bending guide block 22.
[0024] Working principle: The robot grabs the processed key to the top of the placement slot 9 and releases it, and the key falls into the area between the V-shaped limit groove 12 and the block 10 in the placement slot 9; when a certain number of keys are stacked and placed in the placement slot 9, the robot suspends the key loading operation.
[0025] Subsequently, the No. 1 telescopic cylinder 8 on the feeding mounting block 3 drives one side of the placement block 7 into the make way groove 4, so that the open end of the placement groove 9 is aligned with the wire outlet of the wire bending mechanism; then, the No. 2 telescopic cylinder 13 on the placement block 7 drives the limit block 11 to move toward the clamping block 10, and clamps the key between the V-shaped limit groove 12 and the clamping block 10; because the V-shaped limit groove 12 cooperates with the key tooth end, and the horizontal plane of the key handle end cooperates with the plane on the clamping block 10, the stacked keys are limited front, back, left and right to achieve neat arrangement.
[0026] The motor 25 on the guide wire installation block 2 drives the guide wire driving wheel 17 to rotate, and the iron wire clamped between the guide wire driving wheel 17 and the guide wire driven wheel 18 is sent into the guide wire hole 20 in the guide wire block 19. After being sent out from the guide wire hole 20, the iron wire enters the round guide groove 23 on the round guide block 22; the iron wire is sent out from the wire outlet after being rounded through the round guide groove 23, and then the iron wire passes through the stringing holes at the handle ends of multiple stacked keys during the ring forming process, and the multiple stacked keys are stringed together. After the iron wire stringing is completed, the motor 25 stops, and the cylinder 5 on the guide wire installation block 2 drives the cutting block 6 to cut the iron wire at the wire outlet.
[0027] The third telescopic cylinder 16 on the feeding mounting block 3 drives the support plate 14 to retract from the bottom of the placement groove 9 into the placement block 7, and the multiple keys that have been strung together fall from the placement groove 9 under their own gravity to complete the unloading operation.
[0028] Since the portion of the support plate 14 corresponding to the opening of the placement groove 9 for stringing the rings is provided with a stringing groove 15, the wire will not string the support plate 14 in during the wire bending and stringing process, and when the No. 3 telescopic cylinder 16 drives the support plate 14 to retract into the placement block 7, the process will not be blocked.
[0029] The bending guide block 22 is provided with a plurality of bending guide grooves 23 distributed at intervals along the axial direction of the bending guide block 22, and the bending guide block 22 is inserted into the mounting hole 21. When the outermost bending guide groove 23 is worn, a certain length of the bending guide block 22 can be pulled out (after the bending guide block 22 is inserted into the mounting hole 21, the fixing rod threadedly connected on the guide wire mounting block 2 will be tightened to fix the bending guide block 22. When the bending guide block 22 needs to be pulled out later, the fixing rod needs to be loosened first) to align the next bending guide groove 23 with the guide wire hole 20. The bending guide block 22 does not need to be replaced until all the bending guide grooves 23 are worn, and the durability is high; the stabilizing block 24 fixed on the guide wire mounting block 2 can clamp the top end of the guide wire block 19 stably and stably support the bending guide block 22, which greatly strengthens the wire bending part and improves the wire bending effect.
