Description

Technical Field

[0001] The utility model relates to a spot welder for assembling optical lenses, belonging to the technical field of optical lens assembly. Background Art

[0002] Spot welding refers to a welding method in which columnar electrodes are used to form solder joints between the contact surfaces of two overlapping workpieces. During spot welding, the workpieces are first pressed together tightly, and then the current is switched on. Under the action of resistance heat, the contact part of the workpieces melts and forms a solder joint after cooling.

[0003] When assembling an optical lens, the optical lens is placed in a lens frame and then welded to fix the optical lens in the lens frame. However, during welding, generally only the lens or the lens frame is fixed. Therefore, the staff needs to hold the unfixed lens or lens frame, making the welding operation difficult.

[0004] The utility model proposes a new solution to the above problems. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a spot welder for assembling optical lenses to solve the problem that the staff needs to hold the unfixed lens or lens frame, making the welding operation difficult.

[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0007] A spot welder for assembling optical lenses includes an assembly table and a spot welder main body installed on the lower surface of the assembly table. A lens fixing mechanism and a lens frame fixing mechanism are fixedly connected to the upper surface of the assembly table. The lens fixing mechanism includes a fixing tube. An elastic pad is fixedly connected to the upper surface of the fixing tube. A through hole communicating with the inside of the fixing tube is opened on the upper surface of the elastic pad. A spring is sleeved inside the fixing tube. A connecting tube that is slidably connected to the inner wall of the fixing tube and slidably connected to the assembly table is provided. The bottom of the connecting tube is sealed. One end of the connecting tube is fixedly connected to a piston that is slidably connected to the fixing tube.

[0008] Preferably, there are three fixing tubes, and a connecting frame is fixedly connected to the bottoms of the connecting tubes on the three fixing tubes.

[0009] Preferably, an electric push rod is fixedly connected to the lower surface of the assembly table, and the output end of the electric push rod is fixedly connected to the connecting frame.

[0010] Preferably, the lens frame fixing mechanism includes a first cylinder, and the output end of the first cylinder is fixedly connected to a mounting seat.

[0011] Preferably, a second cylinder is fixedly connected to the upper surface of the mounting seat, and a connecting sleeve is inserted into the output end of the second cylinder.

[0012] Preferably, a clamping plate is fixedly connected to the surface of the connecting sleeve, and the corners of the side surface of the clamping plate are rounded.

[0013] Preferably, the four corners of the upper surface of the assembly table are rounded, and an anti-collision pad is fixedly connected to the side surface of the assembly table.

[0014] Preferably, a support leg is fixedly connected to the lower surface of the assembly table, and a connecting rib is fixedly connected to the surface of the support leg.

[0015] The beneficial technical effects of the present utility model: By placing the optical lens on the upper surface of the elastic pad and then pressing it tightly, the elastic pad is closely attached to the surface of the optical lens.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the technical solution of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and drawings. However, the implementation manners of the present utility model are not limited thereto.

[0023] As Figures 1-5 shown, a spot welder for assembling optical lenses provided in this embodiment includes an assembly table 1 and a spot welder main body 2 installed on the lower surface of the assembly table 1. A lens fixing mechanism and a frame fixing mechanism are fixedly connected to the upper surface of the assembly table 1. The lens fixing mechanism includes a fixing tube 3. An elastic pad 4 is fixedly connected to the upper surface of the fixing tube 3. A through hole 5 communicating with the inside of the fixing tube 3 is opened on the upper surface of the elastic pad 4. A spring 6 is sleeved inside the fixing tube 3. A connecting tube 8 that is slidably connected to the inner wall of the fixing tube 3 and slidably connected to the assembly table 1 is provided. The bottom of the connecting tube 8 is sealed. One end of the connecting tube 8 is fixedly connected to a piston 7 that is slidably connected to the fixing tube 3. The number of the fixing tubes 3 is three. A connecting frame 9 is fixedly connected to the bottom of the connecting tubes 8 on the three fixing tubes 3. An electric push rod 10 is fixedly connected to the lower surface of the assembly table 1. The output end of the electric push rod 10 is fixedly connected to the connecting frame 9. First, start the electric push rod 10. The electric push rod 10 drives the connecting tube 8 to move upward through the connecting frame 9, so that the piston 7 moves upward, thereby compressing the spring 6 and discharging the air inside the fixing tube 3 from the through hole 5. Then, place the optical lens on the upper surface of the elastic pad 4 and then press it tightly, so that the elastic pad 4 is in close contact with the surface of the optical lens. Close the electric push rod 10. Under the action of the elastic force of the spring 6, drive the piston 7 and the connecting tube 8 to move downward, so that the inside of the fixing tube 3 is in negative pressure, thereby sucking and fixing the optical lens.

[0024] In this embodiment, as Figure 1 and Figure 5 shown, the frame fixing mechanism includes a first cylinder 11. The output end of the first cylinder 11 is fixedly connected to a mounting seat 12. A second cylinder 13 is fixedly connected to the upper surface of the mounting seat 12. A connecting sleeve 15 is inserted into the output end of the second cylinder 13. A clamping plate 14 is fixedly connected to the surface of the connecting sleeve 15. The side corners of the clamping plate 14 are rounded. The four corners of the upper surface of the assembly table 1 are rounded. An anti-collision pad 16 is fixedly connected to the side surface of the assembly table 1. First, place the frame between the clamping plates 14, and then start the second cylinder 13. The second cylinder 13 drives the clamping plate 14 to move, and clamps the side surface of the frame through the clamping plate 14 to fix the frame. Then start the first cylinder 11. The first cylinder 11 drives the clamping plate 14 to move downward through the connecting seat 12, and then drives the frame to move downward, so as to place the optical lens into the frame, facilitating the welding operation.

[0025] In this embodiment, as Figure 1 shown, support legs 17 are fixedly connected to the lower surface of the assembly table 1. Connecting ribs 18 are fixedly connected to the surface of the support legs 17. The assembly table 1 is supported by the support legs 17.

[0026] In this embodiment, as Figures 1-5 shown, the working principle of a spot welder for assembling optical lenses provided in this embodiment is as follows:

[0027] First, start the electric push rod 10. The electric push rod 10 drives the connecting pipe 8 to move upward through the connecting frame 9, causing the piston 7 to move upward, thereby compressing the spring 6, discharging the air inside the fixed pipe 3 from the through hole 5. Then, place the optical lens on the upper surface of the elastic pad 4 and press it tightly so that the elastic pad 4 is in close contact with the surface of the optical lens. Close the electric push rod 10. Under the action of the elastic force of the spring 6, drive the piston 7 and the connecting pipe 8 to move downward, making the inside of the fixed pipe 3 in a negative pressure state, and then sucking and fixing the optical lens. Place the spectacle frame between the clamping plates 14, then start the second cylinder 13. The second cylinder 13 drives the clamping plates 14 to move, and clamps the side of the spectacle frame through the clamping plates 14 to fix the spectacle frame. Then start the first cylinder 11. The first cylinder 11 drives the clamping plates 14 to move downward through the connecting seat 12, and then drives the spectacle frame to move downward, placing the optical lens into the spectacle frame to facilitate the welding process.

[0028] As described above, it is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
