[0002] In the conventional glasses processing process, the glasses feet need to be processed, and when the glasses feet are processed, the hinge support rod needs to be inserted and fixed in the glasses feet.

[0003] When inserting the hinge rods into the temples of the glasses, the hinge rods need to be transported one by one, and then the feeding mechanism grabs the hinge rods. Since the hinge rods are small, they are easy to touch adjacent hinge rods when grabbing them, affecting the precise transportation of the hinge rods.

[0004] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Summary of the invention

[0005] The purpose of the present invention is to provide a hinge support rod conveying device in a spectacles pin insertion machine, which ensures that the hinge support rods are conveyed in a vertical state and facilitates the grasping structure to grasp them accurately one by one.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a hinge support rod conveying device in an eyeglass pin insertion machine, comprising a connecting frame, the connecting frame is provided with a conveying frame, the conveying frame is provided with a conveying channel for conveying hinge support rods in sequence, the conveying channel is inclined, and the hinge support rods are arranged in a vertical state, the conveying frame is provided with a moving component for moving the hinge support rods in the conveying channel a certain distance and facilitating grasping, and an anti-drop structure for preventing adjacent hinge support rods from falling after the hinge support rods move a certain distance.

[0007] The present invention is further configured as follows: the moving assembly includes a sliding frame horizontally slidably connected to the conveying frame, an abutment portion arranged on the sliding frame and abutted by the side wall of the hinge support rod, a clamping plate hinged to the sliding frame and clamping the hinge support rod with the abutment portion, a clamping portion arranged at the lower end surface of the clamping plate and corresponding to the abutment portion, and a clamping cylinder arranged on the sliding frame and driving the clamping plate to rotate, the clamping plate rotation axis is horizontally arranged and the hinge position with the sliding frame is located at the middle section of the clamping plate, the output shaft of the clamping cylinder extends and pushes the clamping portion to move toward the abutment portion so that the clamping portion and the abutment portion clamp the hinge support rod.

[0008] The present invention is further configured as follows: a torsion spring is provided at the hinged end between the clamping plate and the conveying frame for driving the clamping portion to rotate away from the abutting portion.

[0009] The present invention is further configured as follows: a limiting structure is provided between the clamping plate and the conveying frame to control the position of the clamping plate and facilitate the hinge support rod to move along the conveying channel to the abutment portion and the clamping portion.

[0010] The present invention is further configured as follows: the limiting structure includes a limiting groove opened at the end position of the conveying frame and for the clamp to be clamped into, an inclined guide surface arranged on the side wall of the limiting groove away from the conveying channel, and a guide wheel arranged on the clamp and abutting against the inclined guide surface, and the guide wheel is located below the hinged end of the clamp and the conveying frame.

[0011] The present invention is further configured as follows: the anti-drop structure includes a blocking cylinder arranged on the conveying frame, the blocking cylinder is horizontally arranged and blocks the conveying channel when the output shaft is extended, and the blocking cylinder is located at the discharge end of the conveying channel.

[0012] The present invention is further configured as follows: the connecting frame is provided with a vibration motor which drives the conveying frame to vibrate and causes the hinge support rod to move along the conveying channel toward the moving component.

[0013] In summary, the present invention has the following beneficial effects:

[0014] When in use, the sliding frame is close to the outlet end of the conveying channel of the conveying frame, and the abutting part and the clamping part are in contact with the two side walls of the outlet end of the conveying channel and are flush with the side walls of the conveying channel, so that only one hinge support rod can slide smoothly to be conveyed between the abutting part and the clamping part, and then the clamping plate is flipped by the clamping cylinder to make the clamping part close to abutting and clamping the hinge support rod, and the driving structure drives the sliding frame to move a certain distance away from the conveying channel, so that the hinge support rod is separated from the adjacent hinge support rod by a certain distance, which is convenient for the hinge support rod to be accurately grasped. In addition, when the hinge support rod is moved away, the anti-drop structure limits the hinge support rod in the conveying channel from continuing to move and prevents it from falling.

[0015] When the clamping part and the abutting part clamp and drive the hinge support rod to move, the clamping cylinder output shaft contracts, and the clamping plate is driven to quickly reset through the torsion spring, so that the clamping part flips away from the abutting part.

[0016] When the torsion spring drives the clamping plate to flip, the clamping part and the abutting part are in an open state. When the driving structure drives the sliding frame to reset, the guide wheel abuts against the inclined guide surface of the limit groove and slides along the inclined guide surface. The guide wheel slides and drives the clamping plate to flip toward the abutting part at a certain angle. When the sliding frame completes the movement toward the conveying channel, the clamping part follows the clamping plate to rotate flush with the side wall of the conveying channel, making it convenient for the next hinge support rod to enter between the clamping part and the abutting part.

[0017] When the output shaft of the blocking cylinder is extended, it blocks and abuts the hinge support rod, restricting the movement of the hinge support rod. When the output shaft of the blocking cylinder is contracted, the hinge support rod can move normally along the conveying channel to between the clamping part and the abutting part.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0026] like Figures 1 to 6 As shown, the present invention proposes a hinge support rod conveying device in a spectacles pin insertion machine, comprising a connecting frame 1, the connecting frame 1 is provided with a conveying frame 2, the conveying frame 2 is provided with a conveying channel 3 for the hinge support rods to be arranged and conveyed in sequence, the conveying channel 3 is inclined, and the hinge support rods are arranged in a vertical state, that is, the lower part of the conveying channel 3 is open, and the tip of the hinge support rod is located below the conveying channel 3 and is exposed. The conveying frame 2 is provided with a moving component for moving the hinge support rod in the conveying channel 3 to move a certain distance and facilitate grasping, and an anti-drop structure for preventing the adjacent hinge support rod from falling after the hinge support rod moves a certain distance, and the connecting frame 1 is provided with a vibration motor 4 for driving the conveying frame 2 to vibrate and move the hinge support rod along the conveying channel 3 toward the moving component.

[0027] The moving assembly includes a sliding frame 5 horizontally slidably connected to the conveying frame 2, an abutment portion 6 arranged on the sliding frame 5 and abutted by the side wall of the hinge support rod, a clamping plate 7 hinged to the sliding frame 5 and clamping the hinge support rod with the abutment portion 6, a clamping portion 8 arranged at the lower end surface of the clamping plate 7 and corresponding to the abutment portion 6, and a clamping cylinder 9 arranged on the sliding frame 5 and driving the clamping plate 7 to rotate. The clamping portion 8 and the abutment portion 6 are respectively arranged on both sides of the hinge support rod, and the rotation axis of the clamping plate 7 is horizontally arranged and the hinged position with the sliding frame 5 is located in the middle section of the clamping plate 7. The output shaft of the clamping cylinder 9 is extended and pushes the clamping portion 8 to move toward the abutment portion 6 so that the clamping portion 8 and the abutment portion 6 clamp the hinge support rod, and the conveying frame 2 is provided with a driving structure for driving the sliding frame 5 to move, and the driving structure can be a cylinder, etc. When in use, the sliding frame 5 is close to the outlet end of the conveying channel 3 of the conveying frame 2, and the abutting part 6 and the clamping part 8 are in contact with the two side walls of the outlet end of the conveying channel 3 and are flush with the side walls of the conveying channel 3, so that only one hinge support rod can slide smoothly to be conveyed between the abutting part 6 and the clamping part 8, and then the clamping cylinder 9 pushes the clamping plate 7 to flip, so that the clamping part 8 is close to abutting and clamping the hinge support rod, and the driving structure drives the sliding frame 5 to move a certain distance away from the conveying channel 3, so that the hinge support rod is separated from the adjacent hinge support rod by a certain distance, which is convenient for the hinge support rod to be accurately grasped. In addition, when the hinge support rod is moved away, the anti-drop structure limits the hinge support rod in the conveying channel 3 from continuing to move and prevents it from falling.

[0028] In order to facilitate the clamping plate 7 to quickly flip in the opposite direction and allow the hinge support rod to fall off when the output shaft of the clamping cylinder 9 contracts, a torsion spring 10 is provided at the hinged end of the clamping plate 7 and the conveying frame 2 to drive the clamping part 8 to rotate away from the abutment part 6. That is, when the clamping part 8 and the abutment part 6 clamp and drive the hinge support rod to move, the output shaft of the clamping cylinder 9 contracts, and the clamping plate 7 is driven to quickly reset through the torsion spring 10, so that the clamping part 8 flips away from the abutment part 6.

[0029] A limiting structure is provided between the clamping plate 7 and the conveying frame 2 to control the position of the clamping plate 7 and facilitate the hinge support rod to move along the conveying channel 3 to the abutment portion 6 and the clamping portion 8. The limiting structure includes a limiting groove 11 opened at the end position of the conveying frame 2 and for the clamping plate 7 to be inserted into, an inclined guide surface 12 provided on the side wall of the limiting groove 11 away from the conveying channel 3, and a guide wheel 13 provided on the clamping plate 7 and abutting against the inclined guide surface 12, and the guide wheel 13 is located below the hinged end of the clamping plate 7 and the conveying frame 2. When the torsion spring 10 drives the clamping plate 7 to flip, the clamping portion 8 and the abutting portion 6 are in an open state. When the driving structure drives the sliding frame 5 to reset, the guide wheel 13 abuts against the inclined guide surface 12 of the limiting groove 11 and slides along the inclined guide surface 12. The guide wheel 13 slides and drives the clamping plate 7 to flip toward the abutting portion 6 at a certain angle. After the sliding frame 5 completes its movement toward the conveying channel 3, the clamping portion 8 follows the clamping plate 7 to rotate to be flush with the side wall of the conveying channel 3, making it convenient for the next hinge support rod to enter between the clamping portion 8 and the abutting portion 6.

[0030] The anti-drop structure includes a blocking cylinder 14 arranged on the conveying frame 2, the blocking cylinder 14 is arranged horizontally and blocks the conveying channel 3 when the output shaft is extended, and the blocking cylinder 14 is located at the discharge end of the conveying channel 3. The output end of the blocking cylinder 14 is located below the conveying channel 3 and can block the protruding and exposed part of the hinge support rod. When the output shaft of the blocking cylinder 14 is extended, it blocks and abuts the hinge support rod, restricting the movement of the hinge support rod. When the output shaft of the blocking cylinder 14 is retracted, the hinge support rod can move normally along the conveying channel 3 to between the clamping part 8 and the abutting part 6.
