[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a double-station lens coupling machine.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The lens cartridge is provided with a vision positioning through hole. The machine table is equipped with a reflection lens on one side of the lens cartridge, a lower vision camera below the vision positioning through hole, a first horizontal vision camera and a second horizontal vision camera on the other side of the lens cartridge. The second horizontal vision camera is arranged corresponding to the reflection lens, and the imaging light of the second horizontal vision camera is reflected by the reflection lens. The imaging light reflected by the reflection lens, the imaging light of the first horizontal vision camera and the imaging light of the lower vision camera are perpendicular to each other and converge at the same focus. Both the left coupling device and the right coupling device include an XYZ-axis driving mechanism installed on the machine table, an X-axis angular displacement platform connected to the driving end of the XYZ-axis driving mechanism, a Y-axis angular displacement platform connected to the output end of the X-axis angular displacement platform, a Z-axis angular displacement platform connected to the output end of the Y-axis angular displacement platform, a jaw mechanism installed on the output end of the Z-axis angular displacement platform, a light curing lamp installed on the output end of the Z-axis angular displacement platform and located on the side of the jaw mechanism, a mounting bracket installed on the output end of the XYZ-axis driving mechanism and located above the jaw mechanism, and a dispensing mechanism and an upper vision camera respectively installed on the mounting bracket. The jaw mechanism, the dispensing mechanism and the upper vision camera are arranged in a staggered manner.

[0006] Further, the XYZ-axis driving mechanism includes an X-axis moving module installed on the machine table, a Y-axis moving module installed on the moving end of the X-axis moving module, and a Z-axis moving module installed on the moving end of the Y-axis moving module.

[0009] Advantages of the present utility model: In practical applications, the circuit board is placed on the coupling positioning table. The lens cassette stores lenses. The left coupling device and the right coupling device respectively couple the lenses onto the circuit board. The left coupling device and the right coupling device work simultaneously without interfering with each other, improving the efficiency of lens coupling. The specific operations of the left coupling device and the right coupling device are as follows: Driven by the XYZ-axis drive mechanism, the jaw mechanism grabs the lens from the lens cassette and moves the lens above the vision positioning through-hole. The lower vision camera, the first horizontal vision camera, and the second horizontal vision camera identify the external shape features and coordinate positions of the lens from three axes. According to the recognition results, the X-axis angular displacement platform, the Y-axis angular displacement platform, and the Z-axis angular displacement platform work together to adjust the coupling angle and position of the lens. Then, driven by the XYZ-axis drive mechanism, the upper vision camera first performs vision positioning on the coupling position of the circuit board. The jaw mechanism pre-couples the lens onto the circuit board. After the pre-coupling operation is completed, the jaw mechanism removes the lens. The dispensing mechanism dispenses glue at the coupling position of the circuit board. The jaw mechanism then couples the lens onto the circuit board after dispensing glue. Finally, the light curing lamp cures the glue. The present utility model uses two coupling devices (the left coupling device and the right coupling device) to respectively couple lenses at different positions of the circuit board, greatly improving the coupling efficiency, and the coupling angle and position of the lens can be adjusted, improving the coupling quality.

The lens cartridge 3 is provided with a vision positioning through hole 6. The machine table 1 is installed with a reflection lens 7 on one side of the lens cartridge 3, a lower vision camera 8 below the vision positioning through hole 6, a first horizontal vision camera 9 and a second horizontal vision camera 10 on the other side of the lens cartridge 3. The second horizontal vision camera 10 is correspondingly arranged with the reflection lens 7. The imaging light of the second horizontal vision camera 10 is reflected by the reflection lens 7. The imaging light reflected by the reflection lens 7, the imaging light of the first horizontal vision camera 9, and the imaging light of the lower vision camera 8 are perpendicular to each other and converge at the same focus; both the left coupling device 4 and the right coupling device 5 include an XYZ-axis driving mechanism 11 installed on the machine table 1, an X-axis angular displacement platform 12 connected to the driving end of the XYZ-axis driving mechanism 11, a Y-axis angular displacement platform 13 connected to the output end of the X-axis angular displacement platform 12, a Z-axis angular displacement platform 14 connected to the output end of the Y-axis angular displacement platform 13, a jaw mechanism 15 installed on the output end of the Z-axis angular displacement platform 14, a light curing lamp 16 installed on the output end of the Z-axis angular displacement platform 14 and located on the side of the jaw mechanism 15, a mounting bracket 17 installed on the output end of the XYZ-axis driving mechanism 11 and located above the jaw mechanism 15, and a dispensing mechanism 18 and an upper vision camera 19 respectively installed on the mounting bracket 17. The jaw mechanism 15, the dispensing mechanism 18, and the upper vision camera 19 are arranged in a staggered manner. Specifically, the X-axis angular displacement platform 12 can provide rotational movement around the X axis. The Y-axis angular displacement platform 13 is a Y-axis angular displacement slide table that can provide rotational movement around the Y axis. The Z-axis angular displacement platform 14 is a Z-axis angular displacement slide table that can provide rotational movement around the Z axis; the first horizontal vision camera 9 and the second horizontal vision camera 10 are arranged in parallel, and the included angle between the reflection lens 7 and the imaging light of the second horizontal vision camera 10 is 45°.

[0018] In practical applications, the circuit board is placed on the coupling positioning table 2. The lens cartridge 3 stores lenses. The left coupling device 4 and the right coupling device 5 respectively couple the lenses onto the circuit board. The left coupling device 4 and the right coupling device 5 work simultaneously without affecting each other, improving the efficiency of lens coupling. The specific operations of the left coupling device 4 and the right coupling device 5 are as follows: Driven by the XYZ-axis drive mechanism 11, the jaw mechanism 15 picks up the lens from the lens cartridge 3 and moves the lens above the vision positioning through hole 6. The lower vision camera 8, the first horizontal vision camera 9, and the second horizontal vision camera 10 identify the shape features and coordinate positions of the lens from three axes. According to the recognition results, the X-axis angular displacement platform 12, the Y-axis angular displacement platform 13, and the Z-axis angular displacement platform 14 work together to adjust the coupling angle and position of the lens. Then, driven by the XYZ-axis drive mechanism 11, the upper vision camera 19 first performs vision positioning on the coupling position of the circuit board. The jaw mechanism 15 pre-couples the lens onto the circuit board. After the pre-coupling operation is completed, the jaw mechanism 15 removes the lens. The dispensing mechanism 18 dispenses glue at the coupling position of the circuit board. The jaw mechanism 15 then couples the lens onto the circuit board after dispensing glue. Finally, the light curing lamp 16 cures the glue. In this utility model, two coupling devices (the left coupling device 4 and the right coupling device 5) respectively couple lenses at different positions of the circuit board, greatly improving the coupling efficiency, and the coupling angle and position of the lens can be adjusted, improving the coupling quality.

One end of the swing arm 26 away from the rotating plate 25 is rotatably connected to the slider 28. The Y-axis angular displacement platform 13 is installed on the rotating plate 25.

[0021] In practical applications, the Y-axis moving mechanism 24 drives the vertical guide rail 27 to reciprocate along the Y-axis. The reciprocating vertical guide rail 27 drives the slider 28 to slide up and down along the vertical guide rail 27, and the swing arm 26 rotates relative to the slider 28. The rotating swing arm 26 drives the rotating plate 25 to rotate around the X-axis, thereby driving the Y-axis angular displacement platform 13 to rotate around the X-axis, and further adjusting the angle of the lens clamped by the clamping jaw mechanism 15.

In practical applications, the motor 29 drives the lead screw 30 to rotate, and the rotating lead screw 30 drives the moving nut 31 to move along the axial direction of the lead screw 30. The moving moving nut 31 drives the translation seat 32 and the vertical guide rail 27 to translate.
