When the piston rod of the side pushing cylinder 104 is retracted, the notch 122 on the pushing platform 121 is just opposite to the feeding groove 115, and when the piston rod of the side pushing cylinder 104 is extended, the notch 122 on the pushing platform 121 is just below the first jaw 119.

[0058] A photoelectric detection mechanism 103 is arranged at the outlet end of the feeding groove 115, which is used to detect the forward or reverse position of the workpiece, and control whether the rotary cylinder 113 rotates according to the signal. The axis of the feeding groove 115 is perpendicular to the axis of the chute 102. The vibration mechanism 116 is connected to the base 118 through a damping mechanism at the bottom, and the damping mechanism is four damping columns 117 arranged in a rectangular shape. The vertical column 101 comprises two vertical columns arranged in parallel, a cross beam 124 is arranged on the vertical column 101, and the cylinder body of the side pushing cylinder 104 and the chute 102 are mounted on the cross beam 124 through a positioning plate 125.

[0059] A proximity switch 114 is arranged above the feeding groove 115, which is used to detect the loading amount of the workpiece. The inlet end of the feeding groove 115 is connected with the circular vibration feeding table 14.

[0060] The lifting cylinder 109 is installed on the mounting platform 123 arranged at the top of the translation support 108.

[0061] The horizontal guide rail 105 slider mechanism comprises matched horizontal guide rail 105 and horizontal slider 107, the horizontal guide rail 105 is installed on the fixed support one 106, and the horizontal slider 107 is installed on the translation support one 108; the longitudinal guide rail 111 slider mechanism comprises matched longitudinal guide rail 111 and longitudinal slider, the longitudinal guide rail 111 is installed on the translation support one 108, and the longitudinal slider is installed on the lifting support one 112.

[0062] The working principle of the station is as follows: multiple hoop shells 18 (workpieces) can be simultaneously fed into the feeding groove 115, the two ends of the hoop shell 18 are connected in a head-to-tail manner and closely arranged in the feeding groove 115, the vibration mechanism 116 vibrates to drive the hoop shell 18 to move towards the discharge end, when the piston rod of the side pushing cylinder 104 is retracted, the notch 122 on the pushing platform 121 is just opposite to the feeding groove 115, at this time, the frontmost hoop shell 18 enters the pushing platform 121 from the notch 122, then the piston rod of the side pushing cylinder 104 is extended to push the pushing platform 121 forward, so that the hoop shell 18 loaded on the pushing platform 121 is located directly below the first clamping jaw 119, the first clamping jaw 119 moves downward to the height of the hoop shell 18 under the action of the lifting cylinder one 109, and clamps the hoop shell 18 from the front and rear end surfaces of the hoop shell 18, if necessary, the rotary cylinder one 113 is actuated to rotate the first clamping jaw 119 by 180°, so as to ensure that the hoop shell 18 is always fed in a forward direction, then the hoop shell 18 is moved to the position of the clamp 13 on the multi-station turntable 12 under the joint action of the lifting cylinder one 109 and the translation cylinder one 110, the clamp 13 clamps the hoop shell 18 to perform subsequent assembly in multiple stations, the first clamping jaw 119 retreats to the original position to wait for the next feeding, and the side pushing cylinder 104 retreats to make room for the next hoop shell 18 to enter the notch 122 of the pushing platform 121. Compared with the prior art, the beneficial effects of the present application are as follows: the side pushing cylinder 104 pushes the hoop shell 18 away from the position of the feeding groove 115, so that the first clamping jaw 119 can clamp the hoop shell 18 from the front and rear end surface direction of the hoop shell 18, the front and rear end surfaces of the hoop shell 18 are the passageway for subsequent assembly, when the clamp 13 on the turntable 12 is converted, the clamp 13 clamps the hoop shell 18 from the two sides of the hoop shell 18, and the first clamping jaw 119 releases the hoop shell 18, which can just make room for the passageway for subsequent assembly of the hoop shell 18, so that the subsequent assembly of the hoop shell 18 is more convenient. In addition, since the side pushing cylinder 104 pushes the hoop shell 18 away from the position of the feeding groove 115, the first clamping jaw 119 can rotate after clamping the hoop shell 18, so that the hoop shell 18 can always be fed in a forward direction, avoiding assembly errors in the reverse direction, and there is no need to pre-adjust the direction of the hoop shell 18 before the feeding groove 115.

[0063] As Figures 11-14As shown, in the second station, the steel strip feeding mechanism 2 comprises a first translational feeding mechanism and a second translational feeding mechanism, characterized in that: the first translational feeding mechanism comprises a first support plate 210 capable of translational movement, a rotary cylinder 207 is fixed on the first support plate 210, a rotary arm 208 is connected to the output shaft end of the rotary cylinder 207, and a third gripper 209 is installed on the rotary arm 208; the second translational feeding mechanism comprises a fixed plate 201, a second support plate 203 capable of translational movement is arranged on the fixed plate 201, a second gripper 206 is hinged to the second support plate 203, and a swing cylinder 205 is arranged on the second support plate 203, with the piston rod extension end of the swing cylinder 205 being connected to the second gripper 206; the translational movement directions of the first translational feeding mechanism and the second translational feeding mechanism are parallel, the output shaft axis of the rotary cylinder 207 is perpendicular to the translational movement direction of the first translational feeding mechanism, and the second gripper 206 is located in the travel direction of the third gripper 209.

[0064] The first translational feeding mechanism comprises a servo motor 214, the output shaft of the servo motor 214 is in transmission connection with a guide rail sliding block assembly 213, and the sliding block of the guide rail sliding block assembly 213 is connected to the first support plate 210.

[0065] The second translational feeding mechanism comprises a servo motor 204, the output shaft of the servo motor 204 is in transmission connection with a guide rail sliding block assembly 215, and the sliding block of the guide rail sliding block assembly 215 is connected to the second support plate 203.

[0066] The fixed plate 201 is provided with two synchronous pulleys 217, one end of the shaft of the servo motor 204 is connected to one of the synchronous pulleys 217, a synchronous belt 216 is wound around the synchronous pulleys 217, and the synchronous belt 216 is connected to the second support plate 203.

[0067] A drag chain 202 is arranged on an upper portion of the fixed plate 201, and one end of the drag chain 202 is connected to the second support plate 203.

[0068] The fixed plate 201 is fixed on a base 212 through a second stand.

[0069] Its working principle: The third gripper 209 grasps the stamped steel strip 17, and the rotating cylinder 207 and rotating arm 208 rotate the steel strip 17 180°. Because the stainless steel strip 17 stamped by the traditional hose clamp steel strip mold is always tail-forward and front-facing, but in actual assembly, the head-forward and back-facing are required, this invention can use the existing combination of two sets of robotic arms to clamp the stainless steel strip out of the mold and rotate it 180 degrees, thus achieving both flipping and reversing, which is the shortest time and has high production efficiency; then it is fed to the second gripper 206 by the translation feeding mechanism, and the second gripper 206 is located at the first In the traveling direction of the three grippers 209, the steel strip 17 fed by the third gripper 209 is moved to the position of the hoop housing via the translational feeding mechanism 2. Then, the swing cylinder 205 is activated, causing the steel strip 17 to swing at an angle to ensure that the steel strip 17 with the forming hole end can be inserted into the reserved socket on the hoop housing 18. After the steel strip 17 is inserted into the socket on the hoop housing 18, the swing cylinder 205 returns to its original position, completing one lateral assembly of the hoop housing 18 and the steel strip 17 of the hose clamp. At other stations on the turntable 12, the steel strip and the hoop housing 18 are pressed and locked, then rolled and screws are installed, thus completing the assembly of the entire hose clamp. The use of the swing cylinder 205 to swing the steel strip 17 at an angle allows the steel strip with the protruding head to be smoothly inserted into the reserved socket on the hoop housing 18. After insertion, the steel strip can be stably placed in the socket for subsequent processing, which allows the steel strip to be better positioned and improves the assembly accuracy of the hose clamp.
