[0040] Combine Figures 1 to 5 The embodiment of the present invention provides a feeding device for welding a glasses tripod, which is used to transport a hinge 5 to a welding station 4, and includes:

[0041] A feeding platform 1 having a conveying channel 11 for accommodating the hinge 5;

[0042] The vibration plate 2 is configured to convey the hinge 5 to the conveying channel 11 of the feeding platform 1 in a preset posture, and the conveying channel 11 is configured to maintain the posture of the hinge 5 unchanged during the conveying process in the conveying channel 11;

[0043] The pushing mechanism 3 is provided on one side of the vibration plate 2 and is configured to push the hinge 5 located in the conveying channel 11 to the welding station 4 .

[0044] In this embodiment, first, a pair of eyeglass frames is pre-placed on welding station 4. The frames can be loaded manually or automatically, such as by a robot. Second, welding station 4 is equipped with a welding head and a positioning mechanism for positioning the hinge 5, which is delivered to welding station 4 in a preset position, and the pre-loaded eyeglass frames. Finally, a welding head is positioned above welding station 4 to weld the frames to the hinge 5. The welding head can be a laser welder or an ultrasonic welder, with ultrasonic welders being preferred in this embodiment.

[0045] The working process is roughly as follows: the vibration plate 2 conveys the hinge 5 to the conveying channel 11 of the feeding table 1 in a preset posture, and the pushing mechanism 3 pushes the hinge 5 in the conveying channel 11 to move along the conveying channel 11 to the welding station 4 in the preset posture. At this time, the glasses tripod is pre-loaded on the welding station 4. When the hinge 5 arrives at the welding station 4, the hinge 5 can be directly conveyed to contact the surface to be welded of the glasses tripod, and then the positioning mechanism is activated to position the glasses tripod and the hinge 5, so that the hinge 5 can be accurately positioned at the welding position on the surface to be welded of the glasses tripod, and then the ultrasonic welding head performs ultrasonic welding on the hinge 5 and the glasses tripod. In this way, the automatic loading of the hinge 5 can be completed, which effectively improves efficiency compared to manual loading.

[0046] In one embodiment, the vibration plate 2 includes a vibration plate 2 body and a vibration trough 22 connected to the vibration plate 2 body, and an outlet end of the vibration trough 22 is connected to the conveying channel 11 .

[0047] Specifically, the feeding platform 1 includes a first material plate 12 and a second material plate 13 spaced apart from the first material plate 12 at a predetermined distance. The distance between the first material plate 12 and the second material plate 13 forms the conveying channel 11, and the distance is greater than the width of the hinge 5 and less than the length of the hinge 5. The first material plate 12 and the second material plate 13 are spaced apart to form the conveying channel 11 for conveying the hinge 5. In this embodiment, to simplify the structure of the feeding device, the first material plate 12 and the second material plate 13 are both straight plates, making the conveying channel 11 a linear channel, which facilitates the movement of the hinge 5 in the conveying channel 11. At the same time, by making the distance between the first material plate 12 and the second material plate 13 greater than the width of the hinge 5 and smaller than the length of the hinge 5, the hinge 5 can roughly maintain the above-mentioned preset posture in the conveying channel 11 after entering the conveying channel 11 from the outlet end of the vibrating material trough 22. Even when pushed by the pushing mechanism 3, it can still roughly maintain the preset posture and be conveyed, thereby ensuring the posture accuracy of the hinge 5 when it is conveyed to the welding station 4.

[0048] Furthermore, a hinge receiving opening 121 is provided on the side of the first material plate 12 facing the vibration disk 2, and the hinge receiving opening 121 is configured to receive the hinge 5 from the outlet end of the vibration trough 22. The vibration trough 22 has a trough width, and the hinge receiving opening 121 has a receiving width. The trough width of the vibration trough 22 is greater than the length of the hinge 5 and smaller than the receiving width of the hinge receiving opening 121. With such a design, the hinge 5 can be conveyed to the hinge receiving opening 121 of the first material plate 12 via the vibration trough 22, and pass through the hinge receiving opening 121 into the conveying channel 11. Since the distance between the first material plate 12 and the second material plate 13 is greater than the width of the hinge 5 and smaller than the length of the hinge 5, the hinge 5 can automatically form the above-mentioned preset posture after passing through the hinge receiving opening 121 and falling into the conveying channel 11.

[0049] In a further embodiment, the pushing mechanism 3 includes a linear drive 31 and a pushing member 32 .

[0050] Specifically, the linear drive 31 is configured to have a waiting position for waiting for the hinge 5 to enter the conveying channel 11 and a pushing position for pushing the hinge 5 to the welding station 4; one end of the pushing member 32 is connected to the output end of the linear drive 31, and the other end extends into the conveying channel 11, and is configured to push the hinge 5 located in the conveying channel 11 to the welding station 4, and the pushing member 32 is configured so that when the linear drive 31 is located in the pushing position, the pushing member 32 at least partially blocks the hinge receiving opening 121. In this embodiment, the linear drive 31 can be a cylinder or a linear motor, and the pushing member 32 can be a thin plate member that can move in the conveying channel 11, and when the cylinder or linear motor is in the pushing position, the thin plate member can at least partially block the hinge receiving opening 121 to prevent the hinge 5 waiting on the vibrating trough 22 from entering the conveying channel 11.

[0051] With this design, the cylinder or linear motor can drive the thin plate to push the hinge 5 located in the conveying channel 11 to the welding station 4, and prevent the hinge 5 waiting in the vibrating trough 22 from entering the conveying channel 11 during the pushing process.

[0052] In order to further ensure that the linear drive 31 moves into position, a corresponding detection switch is provided to detect whether the linear drive 31 moves into position.

[0053] Specifically, the pushing mechanism also includes a waiting position detection switch and a pushing position detection switch. The waiting position detection switch is disposed on the linear actuator 31 and is configured to detect whether the linear actuator 31 has returned to the waiting position. The pushing position detection switch is disposed on the linear actuator 31 and is configured to detect whether the linear actuator 31 has advanced to the pushing position. With this design, when the waiting position detection switch detects that the linear actuator 31 is in position, the system determines that the pushing member 32 has returned to the waiting position. After a preset waiting time, the linear actuator 31 activates again, driving the pushing member 32 to push the hinge 5 to the welding station 4. When the pushing position detection switch detects that the linear actuator 31 is in position, the system determines that the pushing member 32 has advanced to the pushing position, and the hinge 5 is pushed to the eyeglass tripod on the welding station 4. The system then controls the linear actuator 31 to return, causing the pushing member 32 to return to the waiting position to push the next hinge 5. Furthermore, when the waiting position detection switch or the pushing position detection switch detects that the linear actuator 31 is not in position, an alarm signal is issued. In this way, the accuracy of the hinge 5 conveying can be guaranteed, and at the same time, the material scrapping caused by the misalignment of the hinge 5 due to the failure of the linear drive 31 to move into place can be avoided.

[0054] Furthermore, the hinge 5 includes a hinge body 51 and a lap joint 52 having a hinge 5 hole. The end of the pusher 32 that contacts the hinge 5 is provided with a groove 321. The groove 321 is configured to accommodate the lap joint 52 of the hinge 5 and abuts the connection between the hinge body 51 and the lap joint 52 during the pushing process of the hinge 5. With this design, the groove 321 on the pusher 32 can serve to position the hinge 5, allowing the hinge 5 to be pushed to the welding station 4 with a certain degree of accuracy, which facilitates the positioning of the positioning mechanism on the welding station 4.

[0055] Furthermore, the pusher 32 includes a main body 322 and a pressure member 323 connected to an end of the main body 322 away from the linear actuator 31. The pressure member 323 is configured to at least partially restrict the height movement of the hinge 5 during the pushing process of the hinge 5. The pressure member 323 can limit the vibration of the hinge 5 during the conveying process, making the conveying of the hinge 5 more stable and improving the conveying accuracy of the hinge 5.

[0056] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
