Description

Technical Field

[0001] This invention relates to the field of visual inspection equipment technology, and more specifically, to a Lens miniature external power clamping device. Background Technology

[0002] In the process of visually inspecting the front and back of lens products, the size of the bowl light source is close to the size of the lens. The bowl light source needs to enclose the lens product within its bowl shape. The remaining space in the loading mechanism is too tight. Due to the limited space between the inside of the bowl light source and the lens, it is impossible to maintain the power supply after the electrostatic or adsorption mechanism rotates without interrupting the airflow. Therefore, external mechanical action is required to clamp the lens, and it is necessary to ensure that the mechanism does not protrude above the convex surface of the product. Traditional cylinder and electric actuator linkage mechanisms cannot meet the space requirements or ensure electrical retention after the product is flipped. Manual clamping of the lens's stepped surface using a knob or clamping mechanism is also possible, but manual clamping is too cumbersome and inconvenient. Summary of the Invention

[0003] To address the aforementioned shortcomings, this invention provides a Lens miniature external power clamping device, which is used for automatic clamping of various compact mechanisms, micro mechanisms, and mechanisms that cannot be powered or pneumatically operated, and has a very small and compact structure.

[0004] The Lens miniature external power clamping device includes: a base with upright plates on both sides and a mounting plate on the top of each upright plate; a push block disposed within the base, with an intermittent annular groove on its upper side; a long connecting rod assembly with a rotating shaft at one end, a pressure roller on the outer circumference of the rotating shaft, the pressure roller being slidably connected to the push block, the middle of the long connecting rod assembly being connected to the two upright plates via a first long pin, and the other end of the long connecting rod assembly being provided with a first short pin; a pressure plate disposed above the first short pin, the pressure plate being rotatably connected to the first short pin; a short connecting rod assembly with a second short pin at one end, the short connecting rod assembly being rotatably connected to the other side of the pressure plate via the second short pin, and the other end of the short connecting rod assembly being connected to the two upright plates respectively via a second long pin; and a pull rod with one end mounted on the base, the other end of the pull rod being slidably connected to the intermittent annular groove to facilitate sliding of the pull rod along the intermittent annular groove in one direction.

[0005] In one embodiment of the present invention, the bottom of the push block is provided with a groove, a compression spring is provided in the groove, and a spring seat assembly is provided at the bottom of the base. The spring seat assembly includes a base plate, a support plate and a limiting pin. The two sides of the base plate are connected to the base by screws. The support plate is perpendicularly connected to the base plate and extends into the groove. The limiting pin is perpendicularly connected to the support plate and extends into the compression spring.

[0006] In one embodiment of the present invention, a screw is provided at the end of the base away from the push block, and a spring is installed between the screw and the pressure plate.

[0007] In one embodiment of the present invention, the intermittent annular chute consists of an uphill section and multiple downhill sections connected in sequence.

[0008] In one embodiment of the present invention, the intermittent annular chute is composed of an uphill section, a first downhill stage, a second downhill stage, and a third downhill stage connected in sequence. The uphill section gradually rises from a trough to a peak. The height of the first downhill stage is lower than the height of the peak of the uphill section. The height of the second downhill stage is lower than the height of the first downhill stage. The height of the third downhill stage is lower than the height of the second downhill stage. The height of the third downhill stage is higher than the height of the trough of the uphill section.

[0009] In one embodiment of the present invention, an arc-shaped contact surface is provided on the upper side of one end of the push block, and a vertical direct contact surface is provided on the lower side of one end of the push block. The push block is slidably connected to the pressure roller through the arc-shaped contact surface and the vertical direct contact surface, respectively.

[0010] In one embodiment of the present invention, both the long connecting rod assembly and the short connecting rod assembly are H-shaped.

[0011] In one embodiment of the present invention, the short link assembly and the long link assembly are arranged in parallel.

[0012] In summary, the present invention provides a miniature external power clamping device for lenses. The beneficial effects of the present invention are:

[0013] The upper side of the push block of this invention adopts the intermittent annular groove locking principle. After the push block is pushed by external power, the pull rod moves in the intermittent annular groove to perform the locking action of pressing and opening. The push block pushes the pressure roller to drive the long connecting rod assembly and the short connecting rod assembly to perform the clamping or opening action, thereby realizing the automated action of clamping and opening of the pressure plate when the carrier itself cannot be powered or pneumatic. Due to the optical detection limitation, the entire mechanism cannot be higher than the convex surface of the lens. The convex surface of the lens is only 1.26mm higher than the carrier. After the highest surface of this device is pressed against the lens, it is flush with the carrier, which fully meets the inspection requirements.

[0014] Furthermore, the structure of this invention is very small and compact, and can be used in a variety of space-constrained situations. It is mainly used for automatic clamping of various compact mechanisms, micro mechanisms and mechanisms that cannot be powered or pneumatically operated.

[0015] Furthermore, the present invention can be self-powered or controlled by external power.

[0016] Furthermore, the stable intermittent mechanical mechanism of the present invention has the advantage of maintaining both states for a long time.

[0017] Furthermore, the inching operation mode of this invention is more energy-efficient than the traditional cylinder and electric actuator methods. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 4 An embodiment provides a Lens miniature external power clamping device, which includes: a base 1, a push block 2, a long connecting rod assembly 3, a pressure plate 4, a short connecting rod assembly 5, and a pull rod 6.

[0027] The base 1 has upright plates 11 on both sides, and an mounting plate 12 on the top of the upright plates 11.

[0028] Push block 2 is set inside base 1, and an intermittent annular groove is provided on the upper side of push block 2.

[0029] One end of the long connecting rod assembly 3 is provided with a rotating shaft 31, and a pressure roller 32 is provided on the outer periphery of the rotating shaft 31. The pressure roller 32 is slidably connected to the push block 2. The middle part of the long connecting rod assembly 3 is connected to the upright plate 11 through a first long pin 33. The other end of the long connecting rod assembly 3 is provided with a first short pin 34.

[0030] Furthermore, an arc-shaped contact surface is provided on the upper side of one end of the push block 2, and a vertical direct contact surface is provided on the lower side of one end of the push block 2. The push block 2 is slidably connected to the pressure roller 32 through the arc-shaped contact surface and the vertical direct contact surface, respectively.

[0031] The pressure plate 4 is located on the upper side of the first short pin 34 and is rotatably connected to the first short pin 34.

[0032] The short connecting rod assembly 5 is arranged in parallel with the long connecting rod assembly 3. One end of the short connecting rod assembly 5 is provided with a second short pin 52. The short connecting rod assembly 5 is rotatably connected to the other side of the pressure plate 4 through the second short pin 52. The other end of the short connecting rod assembly 5 is connected to the upright plate 11 through the second long pin 51.

[0033] Furthermore, both the long link assembly 3 and the short link assembly 5 are H-shaped.

[0034] One end of the pull rod 6 is mounted on the base 1, and the other end of the pull rod 6 is slidably connected to the intermittent annular slide groove to facilitate unidirectional sliding of the pull rod 6 along the intermittent annular slide groove. The upper side of the push block 2 adopts the intermittent annular slide groove locking principle. After the push block 2 is pushed by external power, the pull rod 6 moves in the slide groove to perform pressing and opening locking actions. The push block 2 pushes the pressure roller 32 to drive the long connecting rod assembly 3 to perform clamping or opening actions. The long connecting rod assembly 3 drives the pressure plate 4 to perform pressing or opening actions.

[0035] like Figure 3 , 4 As shown, one end of the pull rod 6 is inserted into the base, and the other end of the pull rod 6 slides freely in the intermittent annular groove.

[0036] The bottom of the push block 2 has a groove, in which a compression spring 8 is installed. The bottom of the base 1 has a spring seat assembly, which includes a base plate 91, a support plate 92, and a limiting pin 93. The base plate 91 is connected to the base 1 on both sides by screws. The support plate 92 is perpendicularly connected to the base plate 91 and extends into the groove. The limiting pin 93 is perpendicularly connected to the support plate 92 and extends into the compression spring 8. The spring seat assembly serves a limiting function.

[0037] A screw is provided at the end of the base 1 away from the push block 2, and a spring 7 is installed between the screw and the pressure plate 4. The spring 7 acts as a buffer during the opening of the Lens stage and pulls the pressure plate 4 back to its original position during the clamping process.

[0038] The intermittent annular chute consists of a sequentially connected uphill section 21 and multiple downhill stages. In this embodiment, as... Figure 5 As shown, the intermittent annular chute consists of an uphill section 21, a first downhill stage 22, a second downhill stage 23, and a third downhill stage 24 connected in sequence. The uphill section 21 gradually rises from a trough 211 to a peak 212. The height of the first downhill stage 22 is lower than the height of the peak 212 of the uphill section 21, the height of the second downhill stage 23 is lower than the height of the first downhill stage 22, and the height of the third downhill stage 24 is lower than the height of the second downhill stage 23, while the height of the third downhill stage 24 is higher than the height of the trough 211 of the uphill section 21. This allows the tie rod 6 to slide in one direction within the intermittent annular chute.

[0039] The working process of this embodiment is as follows: External power pushes the push block 2, and the pull rod 6 moves in the intermittent annular slide from the uphill section 21 to the first downhill stage 22, and then to the second downhill stage 23. The push block 2 pushes the pressure roller 32, and the pressure roller 32 drives the long connecting rod assembly 3 and the short connecting rod assembly 5 to open. The robot puts the Lens into the carrier, and then the compression spring 8 drives the push block 2 to return to its original position. The pull rod 6 moves in the intermittent annular slide from the second downhill stage 23 to the third downhill stage 24, and then to the trough of the uphill section 21. At the same time, the spring 7 drives the pressure plate 4 to return to its original position, realizing the pressure plate 4 to perform the clamping action. Thus, the clamping and opening action of the pressure plate 4 is realized when the carrier itself cannot be powered or pneumatic.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
