Detailed Implementation

[0025] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0026] like Figures 1 to 6 As shown, this embodiment designs a feeding mechanism for the temple 1 of an eyeglasses, including a conveyor rail, a connecting frame 5, a linear vibrator 6, a pressing mechanism, a blocking mechanism, a first detector 9, and a second detector 10.

[0027] The conveyor rail is provided with a conveying channel for the temple 1 to pass through. The conveying channel includes a straight section 14 and a curved section 15 arranged along its conveying direction. The straight section 14 and the curved section 15 intersect, allowing the temple 1 in the straight section 14 to enter the curved section 15. The curvature angle of the curved section 15 in the horizontal direction is 90°±5°. The width of the conveying channel is greater than the thickness of the main body of the temple 1, and the thickness of the hinge end of the temple 1 is greater than the width of the conveying channel, so that the hinge end of the temple 1 is supported by the conveyor rail, and the main body of the temple 1 hangs down naturally.

[0028] The conveyor rail includes a U-shaped connector 2 and two parallel conveyor side plates 3 and 4. The U-shaped connector 2 connects the first and second conveyor side plates 3 and 4 at their ends and is used to fix their relative positions. The gap between the first and second conveyor side plates 3 and 4 forms the conveying channel. Under the vibration of the linear vibrator 6, the temple 1 can move along the conveying channel and continuously enter the curved section 15, so that subsequent process equipment can grasp the temple 1 at the curved section 15.

[0029] The upper edge of the second conveying side plate 4 is higher than the upper edge of the first conveying side plate 3. Under the vibration of the conveying rail frame, when the hinge end of the eyeglass temple 1 comes into contact with the second conveying side plate 4, the eyeglass temple 1 can be horizontally rotated, so that the hinge end of the eyeglass temple 1 can fall to the upper edge of the first conveying side plate 3.

[0030] The linear vibrator 6 can be a commercially available product. It can be a permanent magnet linear motor and linear vibrator disclosed in CN117566349A, or a structure disclosed in CN103056096A or CN103056096A. Details are not provided here.

[0031] The connecting frame 5 connects the conveyor rail frame and the linear vibrator 6, and is used to fix the two together and transmit vibration. The shape of the connecting frame 5 can be various, which will not be described in detail here. It can be adapted to the connection between the conveyor rail frame and the linear vibrator 6.

[0032] A pressing mechanism is located at the intersection of the straight section 14 and the curved section 15, and is used to release or block the temple 1. The pressing mechanism includes a pressing telescopic cylinder 7 and a pressing head. The pressing telescopic cylinder 7 is fixed on the conveyor rail frame, and a through hole perpendicular to the conveyor channel is provided on the side wall of the conveyor channel. The pressing head is located in the through hole and connected to the pressing telescopic cylinder 7. The pressing head is used to press against the temple 1 in the conveyor channel. The pressing telescopic cylinder 7 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0033] The blocking mechanism is also located at the intersection of the straight section 14 and the curved section 15. The pressing mechanism and the blocking mechanism are used to release or block different temples 1, so that the temples 1 enter the curved section 15 one by one. The blocking mechanism includes a blocking rod 12, a blocking frame 11, and a blocking telescopic cylinder 8. The blocking telescopic cylinder 8 is fixed on the conveyor rail. The blocking rod 12 is connected to the telescopic end of the blocking telescopic cylinder 8 through the blocking frame 11. Two blocking frames 11, one above the other, can be set on the blocking frame 11 to block the upper and lower parts of the temples 1. The blocking rod 12 can extend into the conveying channel to block the temples 1. The blocking telescopic cylinder 8 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0034] A baffle 13 is provided at the end of the curved section 15 to prevent the temple of the glasses 1 from falling out of the conveying channel. A second detector 10 is provided at the end of the curved section 15. The first detector 9 can be an infrared detection sensor, and the second detector 10 is used to detect whether there is a temple of the glasses 1 at the baffle 13.

[0035] The connecting frame 5 is fixed above the linear vibrator 6, and the upper part of the connecting frame 5 is fixedly connected to the conveyor rail frame.

[0036] The first detector 9 is located at the end of the straight section 14. The first detector 9 can be an infrared detection sensor. The first detector 9 is used to detect whether there is a temple 1 at the stop bar 12.

[0037] like Figure 1As shown, when the two eyeglass temple 1 feeding mechanisms are installed side by side, the curved segments 15 of the two eyeglass temple 1 feeding mechanisms bend towards each other, so that the two eyeglass temple 1s are fed separately by the two eyeglass temple feeding mechanisms, thereby meeting the assembly requirements of one eyeglass with two eyeglass temple 1s.

[0038] When the eyeglass temple feeding mechanism in this embodiment is in use:

[0039] When the eyeglass temple 1 enters the straight section 14 from its beginning, it moves along the conveying channel towards the curved section 15 under the vibration of the linear vibrator 6. When it reaches the intersection of the straight section 14 and the curved section 15, the blocking mechanism's blocking telescopic cylinder 8 controls the blocking rod 12 to extend, thereby blocking the eyeglass temple 1. Then, the pressing head of the pressing mechanism extends to press the second eyeglass temple 1 in the conveying direction, and then retracts the blocking rod 12, allowing the first eyeglass temple 1 in the conveying direction to enter the curved section 15, where it is gripped by subsequent process equipment at the baffle 13. After the eyeglass temple 1 in the curved section 15 is gripped, the blocking rod 12 extends and the pressing head retracts, causing the second eyeglass temple 1 to be blocked by the blocking rod 12. This process is repeated, allowing the eyeglass temples 1 to enter the curved section 15 one by one and be gripped.

[0040] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
