Description

Technical Field

[0001] This utility model relates to the field of lens processing testing technology, and specifically discloses a lens processing testing device that is easy to adjust. Background Technology

[0002] In the optical lens manufacturing process, the inspection of lens surface quality, thickness uniformity, and curvature accuracy is a key step to ensure product qualification.

[0003] Existing easily adjustable lens processing inspection devices primarily rely on manual operation: operators must manually place the lens on the inspection table, manually adjust its position, roughly fix it with clamps, and then use laser inspection equipment to measure point by point. This method has significant drawbacks:

[0004] (1) Poor positioning accuracy: When the lens is placed manually, its geometric center is difficult to coincide with the focal point of the detection head, which leads to the deviation of the measurement position, especially for aspherical lenses, which will introduce curvature measurement error;

[0005] (2) Low efficiency: Each lens needs to be individually loaded, positioned, inspected and unloaded, which takes a long time on average and cannot meet the needs of mass production. Therefore, a lens processing inspection device that is easy to adjust is needed to solve the above problems. Utility Model Content

[0006] This invention proposes a conveniently adjustable lens processing inspection device, which improves positioning accuracy and production efficiency through the cooperation of a centering clamping mechanism and an automatic loading and unloading mechanism.

[0007] This invention is implemented as follows: a conveniently adjustable lens processing inspection device includes a support, with a centering clamping mechanism and an automatic loading / unloading mechanism disposed above the support.

[0008] The centering clamping mechanism includes a support platform disposed above the bracket. Four first electric actuators arranged in a circular array are installed above the support platform. The output ends of the four first electric actuators are all fixedly connected to arc-shaped clamps. A circular hole is opened through the upper end of the support platform.

[0009] The automatic loading and unloading mechanism includes a column fixedly connected to the rear end of the support frame, a U-shaped frame fixedly connected to the front end of the column, a lead screw rotatably connected inside the U-shaped frame, a slider threadedly connected to the outer wall of the lead screw, a support plate fixedly connected to the front end of the slider, a laser detection head installed at the lower end of the support plate, a second electric push rod installed at the upper end of the support plate, the output end of the second electric push rod passing through the support plate and fixedly connected to a mounting plate, and a suction cup installed at the lower end of the mounting plate.

[0010] A third electric actuator is installed at the bottom of the bracket. The output end of the third electric actuator passes through the bracket and is fixedly connected to a push plate. A storage bin is placed at the top of the bracket, and a disc is slidably connected inside the storage bin.

[0011] As a preferred embodiment of the lens processing testing device of this utility model, which is easy to adjust, a motor with its output end fixedly connected to the lead screw is installed at the left end of the U-shaped frame.

[0012] As a preferred embodiment of the lens processing testing device of this utility model, which is easy to adjust, an air pump is installed at the lower end of the support plate, and the suction cup is connected to the air pump through an air pipe.

[0013] As a preferred embodiment of the lens processing testing device of this utility model, which is easy to adjust, an alarm is installed at the upper end of the support plate and a controller is installed at the rear end of the column.

[0014] As a preferred embodiment of this utility model of a conveniently adjustable lens processing testing device, a conveyor is provided at the left end of the bracket.

[0015] As a preferred embodiment of the lens processing testing device of this utility model, which is easy to adjust, the upper end of the bracket is fixedly connected to an arc-shaped positioning plate.

[0016] As a preferred embodiment of the lens processing testing device of this utility model, which is easy to adjust, the rear end of the slider abuts against the inner wall of the U-shaped frame.

[0017] As a preferred embodiment of the lens processing testing device of this utility model, which is easy to adjust, multiple fixed columns are fixedly connected between the support platform and the bracket.

[0018] As a preferred embodiment of the present invention, a conveniently adjustable lens processing testing device, the upper end of the bracket is provided with a groove.

[0019] The beneficial effects of this utility model are:

[0020] This invention significantly improves operational accuracy and stability through the coordinated action of a four-jaw synchronous clamping mechanism and a lifting guide assembly: the four arc-shaped clamping plates driven by the first electric push rods are evenly distributed around the circumference at 90°, ensuring uniform clamping force distribution and aligning the geometric center of the lens with the axis of the circular hole in the support platform. This eliminates the need for repeated manual adjustment of the lens position and completely solves the problem of low accuracy in manual positioning.

[0021] The integrated detection-removal module significantly reduces the operation cycle: the laser detection head and the suction cup are fixed to the same support plate, and only a single lead screw is needed to quickly switch between detection positioning and removal positioning. The second electric push rod vertically drives the suction cup to rise and fall, avoiding interference with the laser scanning path and achieving non-destructive picking and placing. Combined with the automatic sorting of the conveyor, the efficiency is improved compared with manual operation, while reducing labor intensity and the risk of human error.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-4 A conveniently adjustable lens processing inspection device includes a support 1, with a centering clamping mechanism and an automatic loading and unloading mechanism disposed above the support 1.

[0030] The centering clamping mechanism includes a support platform 3 set above the bracket 1. Four first electric push rods 14 arranged in a circular array are installed above the support platform 3. The output ends of the four first electric push rods 14 are all fixedly connected to arc-shaped clamping plates 5. A circular hole is opened through the upper end of the support platform 3.

[0031] The automatic loading and unloading mechanism includes a column 4 fixedly connected to the rear end of the support 1, a U-shaped frame 23 fixedly connected to the front end of the column 4, a lead screw 6 rotatably connected inside the U-shaped frame 23, a slider 8 threadedly connected to the outer wall of the lead screw 6, a support plate 9 fixedly connected to the front end of the slider 8, a laser detection head 22 installed at the lower end of the support plate 9, a second electric push rod 10 installed at the upper end of the support plate 9, the output end of the second electric push rod 10 passes through the support plate 9 and is fixedly connected to a mounting plate 13, and a suction cup 12 is installed at the lower end of the mounting plate 13.

[0032] A third electric actuator 18 is installed at the bottom of the bracket 1. The output end of the third electric actuator 18 passes through the bracket 1 and is fixedly connected to a push plate 20. A storage bin 17 is placed at the top of the bracket 1. A disc 19 is slidably connected inside the storage bin 17.

[0033] In this embodiment: multiple lenses are stacked in the storage bin 17 in advance and supported by the bottom disc 19. The third electric push rod 18 at the bottom of the bracket 1 pushes the push plate 20 and the disc 19 to move upward, lifting the uppermost lens to the clamping position of the support platform 3. The four first electric push rods 14 synchronously drive the circumferentially distributed arc-shaped clamping plates 5 to move relative to each other and clamp the edge of the lens to achieve automatic centering.

[0034] Subsequently, the lead screw 6 inside the U-shaped frame 23 drives the slider 8 to move horizontally, causing the laser detection head 22 under the support plate 9 to be positioned directly above the center of the lens for scanning and detection. After the detection is completed, the lead screw 6 continues to adjust the position of the slider 8 so that the suction cup 12 is aligned with the center of the lens. The second electric push rod 10 pushes the mounting plate 13 down, the suction cup 12 adsorbs the lens, and at the same time the arc-shaped clamp 5 is released. Finally, the lens is transferred to the conveyor 16 for sorting and unloading through the lead screw 6, completing the fully automatic cycle operation.

[0035] As a technical optimization of this utility model, a motor 7 with its output end fixedly connected to the lead screw 6 is installed at the left end of the U-shaped frame 23.

[0036] In this embodiment, the lead screw 6 can be driven to rotate by the motor 7.

[0037] As a technical optimization of this utility model, an air pump 11 is installed at the lower end of the support plate 9, and the suction cup 12 is connected to the air pump 11 through an air pipe.

[0038] In this embodiment: when the air pump 11 is started, it generates a strong negative pressure airflow, which is transmitted to the suction cup 12 through the air pipe, so that the suction cup 12 and the lens surface form a vacuum sealing area, generating an adsorption force to ensure that the lens is firmly gripped.

[0039] As a technical optimization of this utility model, an alarm is installed at the upper end of the support plate 9, and a controller is installed at the rear end of the column 4.

[0040] In this embodiment, the controller is electrically connected to multiple first electric actuators 14, second electric actuators 10, third electric actuators 18, an alarm, a laser detection head 22, and a motor 7, so that the controller can control the operation of multiple first electric actuators 14, second electric actuators 10, third electric actuators 18, an alarm, a laser detection head 22, and a motor 7.

[0041] As a technical optimization of this utility model, a conveyor 16 is provided at the left end of the support 1.

[0042] In this embodiment, the inspected lens can be transported by the conveyor 16.

[0043] As a technical optimization of this utility model, an arc-shaped positioning plate 15 is fixedly connected to the upper end of the bracket 1.

[0044] In this embodiment, the position of the storage bucket 17 can be positioned by the arc-shaped positioning plate 15.

[0045] As a technical optimization of this utility model, the rear end of the slider 8 abuts against the inner wall of the U-shaped frame 23.

[0046] In this embodiment, the rear end of the slider 8 abuts against the inner wall of the U-shaped frame 23, which can prevent the slider 8 from rotating axially.

[0047] As a technical optimization of this utility model, multiple fixed columns 2 are fixedly connected between the support platform 3 and the bracket 1.

[0048] In this embodiment, the support platform 3 can be supported and fixed by multiple fixed columns 2.

[0049] As a technical optimization of this utility model, the upper end of the bracket 1 is provided with a groove 21.

[0050] In this embodiment, the groove 21 can be used to store the push plate 20.

[0051] The working principle and usage process of this utility model are as follows: In use, multiple lenses are stacked in the storage bin 17 and supported by the bottom disc 19. The storage bin 17 is placed on the upper end of the support 1, so that the outer wall of the storage bin 17 abuts against the inner wall of the arc-shaped positioning plate 15. The controller causes the third electric push rod 18 at the bottom of the support 1 to push the push plate 20 and the disc 19 upward, lifting the uppermost lens to the clamping position of the support platform 3. The four first electric push rods 14 synchronously drive the circumferentially distributed arc-shaped clamping plates 5 to move relative to each other and clamp the edge of the lens, thereby achieving automatic centering.

[0052] Subsequently, motor 7 drives lead screw 6 to rotate, and lead screw 6 drives slider 8 to move horizontally, causing the laser detection head 22 under support plate 9 to be positioned directly above the center of the lens for scanning and detection. After the detection is completed, lead screw 6 continues to adjust the position of slider 8 so that suction cup 12 is aligned with the center of the lens. Second electric push rod 10 pushes mounting plate 13 down, suction cup 12 picks up the lens, and arc clamp 5 is released at the same time. Finally, the lens is transferred to conveyor 16 for sorting and unloading through lead screw 6, completing the fully automatic cycle operation. The controller can be set to move the third electric push rod 18 upwards by the same distance each time.
