[0062] Specifically, a first guide rail is provided on the worktable 100, which is arranged along a first direction. A first slider is slidably arranged on the first guide rail. The base plate 110 can be fixed on the first slider, so that the base plate 110 can move relative to the worktable 100 along the first direction.

[0063] A positioning block can be provided on the base plate 110, which can restrict the movement of the tooling assembly 200 relative to the base plate 110 in a first direction or a second direction. That is, after the tooling assembly 200 of this disclosure is placed on the base plate 110, it will not have any horizontal displacement relative to the base plate 110.

[0064] The tooling assembly 200 disclosed herein may also be configured as one, and the number of tooling assemblies 200 is not limited in this disclosure.

[0065] Structurally, the tooling assembly 200 disclosed herein includes a frame body 210 and a crossbar 220 disposed on the frame body 210; wherein, the crossbar 220 is used to form a positioning assembly, that is, the crossbar 220 can position the lens and store the lens in the positioning assembly.

[0066] Specifically, the cross bars 220 of the present disclosure can be arranged in multiple numbers, and two adjacent cross bars 220 can form a positioning assembly, whereby the positioning assembly can be arranged in at least one row. When there are multiple positioning assemblies (i.e. two or more positioning assemblies), the two or more positioning assemblies are arranged in parallel with each other, i.e. the cross bars 220 are arranged in parallel with each other.

[0067] The tool assembly 200 of the present disclosure further comprises a bottom positioning bar arranged on the frame body 210, and a positioning groove can be formed on the upper surface of the bottom positioning bar, at least part of the lens is arranged in the positioning groove of the bottom positioning bar, and the positioning of the lens is realized by the bottom positioning bar and the cross bar together.

[0069] The positioning assembly has a length direction, which can be the length direction of the cross bar 220. Moreover, the cross bar 220 is arranged substantially horizontally.

[0070] The lenses of the present disclosure can be arranged in parallel along the length direction of the positioning assembly, and the axis direction of the lenses is parallel or substantially parallel to the length direction of the positioning assembly. In order to accurately position the lenses, a plurality of positioning grooves can be formed on the cross bar 220 of the present disclosure, and the openings of the positioning grooves of the same positioning assembly are opposite, whereby the lenses can be held by the two opening-opposite positioning grooves. Moreover, since the positioning grooves are uniformly arranged along the length direction of the cross bar 220, the lenses can also be arranged at equal intervals along the length direction.

[0071] The clamping assembly 300 of the present disclosure is used to clamp the lens barrel. Specifically, after the clamping assembly 300 of the present disclosure clamps the lens barrel, the axis of the lens barrel can be arranged substantially vertically, whereby the lenses can be conveniently mounted on the lens barrel.

[0072] In a specific embodiment, as Figure 1 indicated, the clamping assembly 300 of the present disclosure can comprise a support frame 310 and a clamping jaw device 320. The support frame 310 is arranged on the workbench 100; for example, the support frame 310 can be fixed at the middle position of the workbench 100; the upper surface of the support frame 310 is provided with two second guide rails, and the two second guide rails are laid along the first direction (i.e. the horizontal direction perpendicular to the length direction of the positioning assembly).

[0073] The clamping jaw device 320 is slidably arranged on the support frame 310, wherein the clamping jaw device 320 moves relative to the support frame 310 along a first direction. Specifically, two second sliding blocks are arranged on each second guide rail, one end of the first sliding plate 330 is connected to one second sliding block arranged on one second guide rail, and the other end of the first sliding plate 330 is connected to another second sliding block arranged on another second guide rail; similarly, one end of the second sliding plate 340 is connected to another second sliding block arranged on one second guide rail, and the other end of the second sliding plate 340 is connected to another second sliding block arranged on another second guide rail; at this time, the first sliding plate 330 and the second sliding plate 340 are arranged substantially in parallel.

[0074] The clamping jaw device 320 includes a driving cylinder and two clamping jaws, wherein the cylinder body of the driving cylinder is fixed to the first sliding plate 330, and the piston rod of the driving cylinder is fixed to the second sliding plate 340, so that the driving cylinder of the present disclosure can move the first sliding plate 330 and the second sliding plate 340 closer to or farther away from each other when working.

[0075] One clamping jaw is arranged on the first sliding plate 330, and another clamping jaw is arranged on the second sliding plate 340, and a V-shaped block 350 is arranged on each clamping jaw, and the openings of the two V-shaped blocks 350 are opposite, so that the lens barrel can be clamped and positioned by the two V-shaped blocks 350, and the axis of the lens barrel can be kept arranged vertically.

[0076] The carrying assembly 400 of the present disclosure is arranged on the workbench 100 through the motion platform 500, wherein the carrying assembly 400 is used to take out the lens from the tool assembly 200 and move the lens to the vicinity of the lens barrel to install the lens on the lens barrel.

[0077] The structure of the carrying assembly 400 and the motion platform 500 will be described in detail below in combination with the drawings.

[0078] Specifically, the motion platform 500 of the present disclosure includes a rotating assembly 510, a first translation assembly 520, and a second translation assembly 530, etc.

[0079] The carrying assembly 400 is connected to the rotating assembly 510, and the axis of the lens is rotated from parallel to the workbench 100 to perpendicular to the workbench 100 through the rotating assembly 510, so that the lens can be located below the carrying assembly 400. In a specific embodiment, the carrying assembly 400 includes a vacuum suction head, which is used to suck the lens and align the central axis of the lens with the central axis of the vacuum suction head.

[0080] The rotating assembly 510 is mounted to the first translation assembly 520, which is used to drive the rotating assembly 510 to move in a direction perpendicular to the workbench 100; that is, the first translation assembly 520 of the present disclosure is a vertical moving platform, which can drive the rotating assembly 510 to move in the vertical direction. In a preferred embodiment, the first translation assembly 520 can be a linear motion mechanism such as a slide cylinder.

[0081] The first translation assembly 520 is arranged on the second translation assembly 530, which is used to drive the first translation assembly 520 to move in a second direction parallel to the workbench 100, wherein the second direction is a horizontal direction perpendicular to the first direction, and the first direction is also a horizontal direction. That is, the second translation assembly 530 of the present disclosure can drive the first translation assembly 520 to move in the horizontal direction, and through the action of the second translation assembly 530, the handling assembly 400 can take out all the lenses from the tool assembly 200 one by one.

[0082] The second translation assembly 530 of the present disclosure can be realized by a linear driving mechanism such as a slide cylinder or an electric cylinder, and the second translation assembly 530 is arranged on the cross beam 540, and the two ends of the cross beam 540 are fixed to the workbench 100 through the stand column 550, so that the moving platform 500 can be mounted on a gantry structure.

[0083] The lens mounting device of the present disclosure can realize automatic mounting of lenses, that is, it can automatically complete the operations of lens grabbing, positioning, mounting, etc., improve the precision and stability of lens mounting, and has the characteristics of high efficiency, precision and stability. Specifically, the lens mounting device can improve the mounting efficiency, improve the production efficiency; reduce the labor operation cost; it can also guarantee the mounting precision and ensure the product quality, realize the automation and rapidization of field lens mounting.

[0084] When the lens mounting device of the present disclosure is used, the operator installs the tool assembly 200 loaded with the cleaned lens to the workbench 100, and makes the tool assembly 200 slide relative to the workbench 100. Then fix the lens barrel on the clamping assembly 300, and control the handling assembly 400 to approach the lens, and control the moving platform 500 to act, so that the handling assembly 400 approaches and adsorbs the lens. Specifically, by controlling the position of the first translation assembly 520 and the position of the tool assembly 200, the axis of the handling assembly 400 can be made to coincide with the center axis of the lens.

[0085] Next, the second translation component 530 is controlled to move, and thus the carrying component 400 approaches the lens, contacts the lens, tightly adsorbs the lens, and then moves out of the area of the tool component 200 upwardly and rightwardly together with the lens. After moving out of the area, the carrying component 400 rotates 90 degrees together with the lens to make the center line of the lens and the carrying component 400 perpendicular to the workbench 100. After being perpendicular, the carrying component 400 is automatically positioned to a position concentric with the lens barrel center, and the carrying component 400 slowly moves downwardly to move the lens adsorbed thereon to a corresponding position in the lens barrel. After the system detects that the lens is installed to the correct position, the carrying component 400 stops adsorption, and then exits upwardly to outside of the lens barrel, repositions to the starting position, and rotates the carrying component 400 to restore to the initial position, to complete the installation of the lens.
