Description

Technical Field

[0001] This utility model relates to the technical field of visual inspection, and in particular to a focusing device for a visual inspection equipment. Background Technology

[0002] With the continuous advancement of optical technology, autofocus devices are increasingly widely used in optical equipment such as cameras and microscopes. The key task of autofocus is to ensure that the lens remains in sharp focus during shooting or observation, thus guaranteeing image quality and observation accuracy. However, with increased usage frequency, dust, contamination, or damage can accumulate on the lens surface, affecting the performance of the device.

[0003] Traditional methods of cleaning and replacing lenses in optical equipment typically rely on manual disassembly, cleaning, or replacement, which is complex and can damage optical components. For example, some equipment uses lens-fixing structures that require the disassembly of numerous components during lens cleaning, making the process inconvenient and prone to causing scratches and contamination. For lenses that cannot be directly touched or disassembled, the cleaning process is even more cumbersome and requires specialized tools and skills, increasing the maintenance costs of optical equipment.

[0023] Example 1

[0024] Reference Figures 1 to 4 A schematic diagram of the overall structure of a focusing device for a visual inspection device is provided. The focusing device for a visual inspection device includes a lens barrel 100, a lens 101 disposed at one end of the lens barrel 100, a floating lens 102 slidably disposed in the lens barrel 100, a lifting assembly 103 for controlling the movement of the floating lens 102, and an offset assembly 104 for controlling the floating lens 102 to deviate from the lens barrel 100. The lifting assembly 103 controls the position of the floating lens 101 in the lens barrel 100 to achieve focusing. The offset assembly controls the floating lens 101 to deviate from the lens barrel 100 to achieve cleaning and replacement of the floating lens 102.

[0025] Furthermore, the lifting assembly 103 includes a mounting platform 103a connected to one side of the lens barrel 100, a driver 103b disposed on the mounting platform 103a, a first bevel gear 103c connected to a power source, a sliding shaft 103d disposed on the mounting platform 103a, a lead screw 103e disposed within the sliding shaft 103d, a second bevel gear 103f disposed at one end of the lead screw 103e, a threaded sleeve 103g disposed between the sliding shaft 103d and the lead screw 103e, and a sleeve formed on the sliding shaft 103d. The system includes a vertical slide groove 103h, a sliding block 103i connected to a threaded sleeve 103g through the vertical slide groove 103h, a connecting rod 103j disposed above the sliding block 103i, a shock-absorbing component 103k connected to the end of the connecting rod 103j, and a lens frame 103l disposed at the end of the shock-absorbing component 103k; a floating lens 102 disposed in the lens frame 103l; a first bevel gear 103c meshing with a second bevel gear 103f; and the outer wall of the threaded sleeve 103g abutting against the inner wall of the sliding shaft 103d. The driver 103b drives the lead screw 103e and the threaded sleeve 103g by controlling the meshing of the first bevel gear 103c and the second bevel gear 103f, thereby controlling the movement of the sliding block 103i in the vertical slide groove 103h, ultimately causing the connecting rod 103j and the lens frame 103l to move up and down, achieving focusing. The floating lens 102 is set in the lens frame 103l and moves up and down within the lens barrel 100 as the connecting rod 103j moves, thus completing the focusing process.

[0026] Furthermore, the offset assembly 104 includes a mounting screw 104a for fixing the sliding block 103i and the connecting rod 103j, and a transverse groove 104b formed on the vertical groove 103h; the ends of the vertical groove 103h and the transverse groove 104b are connected through each other; the offset assembly 104 causes the floating lens 102 to deviate from the lens barrel 100 via the driver 103b. Specifically, when the lens frame 103l is driven upward by the driver 103b and moves out of the lens barrel 100, the sliding block 103i slides from the vertical groove 103h to the transverse groove 104b. The driver 103b continues to operate, changing the vertical sliding of the sliding block 103i to a circular rotation, causing the lens frame 103l to rotate along with the sliding block 103i, thereby causing the floating lens 102 to deviate from the lens barrel 100.

[0027] Furthermore, the lifting assembly 103 drives the first bevel gear 103c, the second bevel gear 103f, the lead screw 103e, the threaded sleeve 103g, the sliding block 103i, the connecting rod 103j, and the lens frame 103l via the driver 103b, thereby controlling the up and down movement of the floating lens 102 to achieve the focusing function; the driver 103b includes a stepper motor.

[0028] Furthermore, the seismic damping component 103k includes a sliding rod 103k-1 slidably disposed at one end of the connecting rod 103j, a spring protrusion 103k-2 sleeved on the sliding rod 103k-1, an adjusting knob 103k-3 disposed at one end of the sliding rod 103k-1, and a compression spring 103k-4 disposed between the connecting rod 103j and the spring protrusion 103k-2; the adjusting knob 103k-3 and the sliding rod 103k-1 are connected by threads. Rotation of the adjusting knob 103k-3 can adjust the compression of the spring protrusion 103k-2, thereby adjusting the seismic damping effect.

[0029] Furthermore, the lifting assembly 103 is controlled by a central control system to adjust the position of the lens; the control system includes a position sensor and a control circuit, which is used to provide real-time feedback on the position information of the floating lens 102 and adjust the driver 103b to achieve focusing.

[0030] Furthermore, the cleaning and replacement of the floating lens 102 is performed by the control system. According to the cleaning cycle or user command, the control system drives the electric starter to shift the offset component 104 to shift the floating lens 102, so as to facilitate lens replacement or cleaning.

[0031] Operation process: Start the driver 103b, which drives the lifting assembly 103. The lifting assembly 103, based on the input target parameters, drives the meshing between the first bevel gear 103c and the second bevel gear 103f, pushing the lead screw 103e and the threaded sleeve 103g to rotate, causing the sliding block 103i to move up and down in the vertical slide groove 103h. Due to the movement of the sliding block 103i, the connecting rod 103j causes the lens frame 103l to move up and down, and the floating lens 102 subsequently adjusts its focus within the lens barrel 100. When the floating lens 102 is aligned with the target and a clear image is obtained, the control system stops the focusing process.

[0032] The actuator 103b moves the lens frame 103l upward. After the lens frame 103l is removed from the lens barrel 100, the sliding block 103i slides from the vertical slide groove to the horizontal slide groove 104b, thereby causing the floating lens 102 to shift out of the lens barrel 100 and ensuring that the floating lens 102 is removed from the lens barrel 100. After the floating lens 102 is removed from the lens barrel 100, the user can easily perform cleaning or replacement operations.

[0033] Beneficial effects: The driver 103b and the precise lifting assembly 103 enable precise up-and-down movement of the floating lens 102, automatically completing the focusing process. The offset assembly 104 allows the floating lens 102 to be offset from within the lens barrel 100, facilitating lens cleaning and replacement. Automated focusing, cleaning, and replacement functions reduce manual operation and improve overall work efficiency.
