DETAILED DESCRIPTION

[0026] 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.

[0027] like Figures 1 to 6 As shown, the present invention proposes a hinge support rod heating guide device in an eyeglass pin insertion machine, comprising a frame 1, wherein the frame 1 is provided with a movable seat 2, a movable structure for driving the movable seat 2 to slide horizontally, a guide block 3 arranged on the movable seat 2 and for the hinge support rod to pass through, and a heating structure arranged on the movable seat 2 and used for heating the guide block 3 and the hinge support rod. The heating structure is located between the guide block 3 and the movable seat 2 and is used for heating the guide block 3. The heating structure can be a high-frequency heater, etc., which is a prior art. The movable structure can be a cylinder, etc., which drives the movable seat 2 to move horizontally. A penetration groove 4 is provided on the upper end surface of the guide block 3 for the hinge support rod to pass through. The length direction of the penetration groove 4 is perpendicular to the sliding direction of the movable seat 2, and the guide block 3 is provided with a guide mechanism for keeping the hinge support rod moving horizontally and linearly.

[0028] When the hinge support rod needs to be inserted into the temple of the glasses, the movable seat 2 is driven by the movable structure to move to the hinge support rod input position, and the hinge support rod is inserted into the insertion groove 4, and then the movable seat 2 is driven by the movable structure to move back until the hinge support rod and the temple of the glasses are in a straight line at the same level, and the pushing structure enters the insertion groove 4 and pushes the end of the hinge support rod, so that the hinge support rod is accurately inserted into the temple of the glasses, realizing high-precision automatic assembly.

[0029] The guide mechanism includes a plurality of rollers 5 arranged in the through groove 4, a connecting block 6 fixed to the guide block 3 and arranged vertically, and an extension groove 7 opened in the connecting block 6 and connected to the through groove 4. The side walls of the extension groove 7 and the through groove 4 are provided with guide grooves 8 for the roller 5 end to be inserted and guide the roller 5. After the roller 5 moves along the guide groove 8, it can move from the through groove 4 to the extension groove 7. In addition, in the present embodiment, a guide ring groove 9 for guiding the hinge support rod is opened in the middle of the side wall of the roller 5, and the guide ring grooves 9 of the plurality of rollers 5 are located in the same plane. The roller 5 is pushed by the hinge support rod and can move along the through groove 4 to the extension groove 7. The hinge support rod is partially penetrated between the roller 5 and the bottom surface of the through groove 4. When the hinge support rod is installed into the insertion groove 4, the tip of the hinge support rod is inserted between the roller 5 and the bottom surface of the insertion groove 4, and the hinge support rod is located at the guide ring groove 9 to realize the positioning of the hinge support rod; when the movable seat 2 moves and makes the hinge support rod and the eyeglass leg in a straight line, the end of the hinge support rod is pushed by the pushing structure to make the tip of the hinge support rod inserted into the eyeglass leg, and the end protrusion structure of the hinge support rod and the pushing structure resist the roller 5 pen shaft to drive the roller 5 to move synchronously relative to the insertion groove 4. When the hinge support rod is completely inserted into the eyeglass leg, the roller 5 enters the extension groove 7. When the pushing structure is separated from the insertion groove 4, the roller 5 is reset by gravity and slides into the insertion groove 4.

[0030] The movable seat 2 is provided with a disengagement component for facilitating the push structure to push the hinge support rod and then quickly disengage from the movable seat 2. The disengagement component includes an opening 10 opened on the side wall of the guide block 3 and for the push structure to move out of the through groove 4, a stopper 11 hinged on the side wall of the guide block 3 and covering the opening 10, and a first torsion spring 12 provided at the hinged end of the stopper 11 and the guide block 3 and driving the stopper 11 to cover the opening 10. The opening 10 is located at the connection position between the through groove 4 and the extension groove 7, the surface of the stopper 11 facing the through groove 4 is flush with the side wall of the through groove 4, the rotation axis of the stopper 11 is horizontally arranged and located at the lower end of the stopper 11, and after the push structure moves to the position of the opening 10, the stopper 11 is pushed and slides away from the through groove 4 from the opening 10. After the pushing structure pushes the hinge support rod to be inserted into the temple of the glasses, the pushing portion of the pushing structure is in the penetration groove 4 and is located at the opening 10. Then, when the moving structure drives the moving seat 2 to translate and receive the hinge support rod again, the pushing portion of the pushing structure abuts against the stopper 11 and flips the stopper 11, thereby achieving the goal of the pushing portion of the pushing structure being separated from the penetration groove 4.

[0031] In this embodiment, in order to ensure that the stopper 11 always covers the opening 10 and allows the roller 5 to slide relative to each other when the push structure pushes the hinge support rod, the guide block 3 is provided with a control structure for controlling the flipping of the stopper 11. The control structure includes a control member 13 that is rotatably connected to the guide block 3 and can abut against the side wall of the stopper 11 away from the guide block 3, a second torsion spring 14 provided at the hinged end of the control member and the guide block 3, a limiting block 15 that is rotatably connected to the guide block 3 and limits the rotation of the control member 13, and a third torsion spring 16 provided at the rotational connection end of the limiting block 15 and the guide block 3. The rotation axis of the control member 13 is horizontal and perpendicular to the length direction of the penetration groove 4. The rotational connection end of the control member 13 and the guide block 3 is located above the penetration groove 4. The rotation axis of the limiting block 15 is horizontal and parallel to the length direction of the penetration groove 4. The control member 13 is provided with a protrusion 17 that can abut against the side wall of the limiting block 15 and limit the downward flipping of the control member 13, and a protrusion 17 for the push structure to abut and drive the control member. 13 rotates the abutment 18, the third torsion spring 16 drives the limit block 15 to deflect downward, the stop block 11 is provided with a shift rod 19 abutting against the limit block 15 to deflect downward, and the contact position between the limit block 15 and the shift rod 19 is arranged in an arc shape, and it is convenient for the shift rod 19 to slide into and push the limit block 15 to flip upward. After the pushing structure moves to the position of the opening 10 and abuts the abutment 18, it drives the control member 13 to rotate and makes the protrusion 17 rotate to the side wall of the limit block 15, and when the stop block 11 turns away from the penetration groove 4, the shift rod 19 separates from the limit block 15, the limit block 15 deflects downward by a certain angle and blocks the protrusion 17, limiting the protrusion 17 from deflecting downward, and after the stop block 11 is reset and the shift rod 19 abuts and pushes the limit block 15 to move upward, the control member 13 deflects downward and resets.

[0032] When the pushing part of the pushing structure moves to the opening 10, the pushing part of the pushing structure contacts the abutment portion 18 and causes the control member 13 to deflect upward, and after the control member 13 deflects upward by a certain angle, it turns away from the surface of the stopper 11 away from the penetration groove 4, and facilitates the stopper 11 to flip outward, and at this time, after the moving seat 2 moves, the pushing part of the pushing structure contacts the stopper 11 and causes the stopper 11 to deflect, so that the gear lever 19 is separated from the limiting block 15, and the third torsion spring 16 drives the limiting block 15 to deflect downward, and the limiting block 15 is turned to After deflecting downward by a certain angle, the raised portion 17 of the control member 13 abuts against the side wall of the limiting block 15 and limits the downward deflection and restoration of the raised portion 17, thereby limiting the position of the control member 13 after deflection. When the stopper 11 is restored and covers the opening 10, the shift rod 19 abuts against the limiting block 15 and pushes the limiting block 15 to flip upward, thereby separating the raised portion 17 from the side wall of the limiting block 15, and then the second torsion spring 14 drives the control member 13 to flip downward, and drives the control member 13 to abut or fit the surface of the stopper 11 away from the through-groove 4.

[0033] The extension groove 7 is slidably connected with a counterweight 20 that pushes the roller 5 to move to the penetration groove 4. The upper end surface of the control member 13 is set in a pointed shape, and the lower end surface of the counterweight 20 is provided with a groove 21 corresponding to the upper end surface of the control member 13. The counterweight 20 is used to quickly drive the roller 5 to move downward and move into the penetration groove 4. In addition, the groove 21 of the counterweight 20 is engaged with the upper end surface of the control member 13 to prevent the control member 13 from turning over when the counterweight 20 is not moved upward.
