Description

Technical Field

[0001] This invention belongs to the technical field of optical device clamping equipment, and in particular relates to an automatic optical device clamping equipment. Background Technology

[0002] Current optical devices require clamping during production, processing, or testing. Taking aging testing of optical devices as an example, before aging testing, the optical device needs to be clamped onto a fixture, then the entire fixture is placed in the aging area for aging. After aging is complete, the fixture is removed, and finally the optical device is taken off the fixture. However, optical devices are very small, and some are sheet-like structures with a surface area of ​​2mm*1mm, making them difficult to handle during clamping.

[0003] In existing technologies, operators need to use equipment such as microscopes for observation, use tweezers to place the optical devices onto the fixture, and then clamp the devices. A single fixture typically holds multiple optical devices, requiring each device to be placed and clamped securely. Because the optical devices are small and numerous, inaccurate placement is common, necessitating adjustments by the operator using tweezers. Therefore, existing methods for clamping optical devices are inefficient, significantly slowing down production. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic clamping device for optical devices, which solves the problem of low efficiency in the clamping of existing optical devices.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] An automatic clamping device for optical devices includes a planar moving structure, a clamping assembly, an adsorption assembly, and a first linear module. The first linear module is vertically arranged, and the adsorption assembly is connected to the first linear module. The first linear module controls the lifting and lowering of the adsorption assembly. The clamping assembly is mounted on the planar moving structure, and the adsorption assembly is located above the clamping assembly. The adsorption assembly is provided with a suction nozzle for adsorbing optical devices.

[0007] A first linear module controls the lifting and lowering of the adsorption assembly, while a planar moving structure controls the position of the clamping assembly. The cooperation of the first linear module and the planar moving structure allows the optical device adsorbed by the adsorption assembly to be placed at any clamping position on the clamping assembly. In other words, the combination of the planar moving structure and the first linear module enables the automatic placement of the optical device onto the clamping assembly, improving the clamping efficiency of the assembly.

[0008] The adsorption assembly also includes a servo motor, which is vertically arranged and whose output shaft is connected to the suction nozzle for controlling the rotation of the suction nozzle in the horizontal plane.

[0009] A servo motor controls the rotation of the suction nozzle, allowing adjustment of the angle at which the nozzle picks up the optical device. This rotates the optical device to match the angle of the clamping assembly, thus accelerating the efficiency of optical device angle adjustment.

[0010] The adsorption assembly also includes a buffer bracket, the suction nozzle is disposed at the bottom of the buffer bracket, and the servo motor is connected to the top of the buffer bracket.

[0011] The buffer bracket acts as a buffer to prevent excessive pressure between the nozzle and the clamping assembly or optical device, thus avoiding damage to the optical device, nozzle, or clamping assembly due to excessive pressure.

[0012] The buffer support includes a fixed support and a sliding support, which are slidably connected. The fixed support and the sliding support are provided with vertical springs. The fixed support is connected to the servo motor, and the suction nozzle is fixed to the bottom of the sliding support.

[0013] It also includes an upper-view lens and a controller. The upper-view lens is disposed on one side of the adsorption assembly and is used to capture the position of the clamping assembly. The signal output terminal of the upper-view lens is connected to the controller and is used to control the movement of the planar moving structure and the first linear module.

[0014] The horizontal position of the upper-level lens remains constant relative to the adsorption assembly, and it can capture the position of the clamping assembly in real time and send the image to the controller. With the cooperation of the upper-level lens and the controller, automatic position adjustment of the optical components can be achieved, improving the clamping position accuracy.

[0015] It also includes a lower-position lens, which is connected to the planar moving structure and is used to capture the angle of the light device adsorbed by the suction nozzle. The signal output terminal of the lower-position lens is connected to the controller and is used to control the movement of the servo motor.

[0016] The lower-position lens captures the angle of the optical device adsorbed by the suction nozzle. In conjunction with the controller, it can automatically adjust the angle of the optical device, thereby improving the clamping angle accuracy.

[0017] It also includes a locking assembly, which is connected to the first linear module. The bottom of the locking assembly is provided with an electric screwdriver for tightening the screws on the clamping assembly.

[0018] The locking structure enables automatic locking of the clamping assembly. After the optical device is placed, the planar moving structure moves the clamping assembly to the underside of the locking structure, whereby the locking structure secures the clamping assembly, improving the locking efficiency of the clamping assembly.

[0019] The electric screwdriver is equipped with buffers on both sides.

[0020] The buffer is used to prevent the electric screwdriver from making a rigid collision with the screw.

[0021] The locking assembly also includes a lifting fixed plate and a lifting sliding plate. The lifting sliding plate is slidably connected to the lifting fixed plate. A vertical spring is provided between the lifting fixed plate and the lifting sliding plate. The electric screwdriver is located at the bottom of the lifting sliding plate.

[0022] The lifting plate, lifting sliding plate, and spring provide a certain amount of pressure to the electric screwdriver, maintaining constant pressure between the screwdriver and the screw and preventing the screwdriver from disengaging. This ensures the stability of the screwdriver's tightening and loosening action.

[0023] A second linear module is also provided between the lifting and fixing plate and the first linear module, which is used to control the independent lifting and lowering action of the electric screwdriver.

[0024] The second module allows for independent raising and lowering of the locking component, ensuring that its movement is not obstructed or interfered with by the adsorption component. Even if the locking component is installed on the same side as the adsorption component, it can still raise and lower independently during operation, preventing the adsorption component from being simultaneously raised and lowered and supported on top of the clamping component, which would otherwise prevent the locking component from contacting the clamping component.

[0025] The present invention has the following beneficial effects:

[0026] This invention uses a suction nozzle to adsorb optical devices, and then combines a linear module and a planar moving structure to achieve automatic adsorption and placement of optical devices. No manual observation of placement is required, which greatly speeds up the clamping efficiency of optical devices and achieves the goal of improving production efficiency.

Detailed Implementation

[0051] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and through specific implementation methods of the embodiments of the present invention.

[0052] Please see Figures 1-3As shown, this invention is an automatic clamping device for optical devices, comprising a two-dimensional cross linear motor 1, an adsorption assembly 9, two locking assemblies 7, a clamping assembly 10, and a pressing assembly 5. The two-dimensional cross linear motor 1 is mounted on a platform, and a slide table 6 is fixed to the two-dimensional cross linear motor 1. The two-dimensional cross linear motor 1 controls the movement of the slide table 6 in a horizontal plane. The clamping assembly 10 and the pressing assembly 5 are mounted on the slide table 6. The slide table 6 includes an upper platform 601 and a lower platform 602. The clamping assembly 10 is fixed to the upper platform 601, and the pressing assembly 5 is fixed to the lower platform 602. The clamping assembly 10 is used to clamp optical devices. The adsorption assembly 9 is fixed to the platform and is equipped with a ceramic suction nozzle 905. The ceramic suction nozzle 905 is used to pick up the optical device and place it in the corresponding position on the clamping assembly 10. After the optical device is placed on the clamping assembly 10, the pressing assembly 5 presses down on the clamping assembly 10 to prevent it from loosening. The locking assembly 7 is fixed on the platform. The locking assembly 7 is provided with a Phillips head 704. The Phillips head 704 is used to tighten the screws on the clamping assembly 10 and lock the clamping assembly 10, so as to achieve complete clamping of the optical device by the clamping assembly 10.

[0053] In other embodiments, the two-dimensional cross linear motor 1, as a planar moving structure, can also be replaced by a vertically arranged lead screw and nut pair structure.

[0054] The platform is mounted on a vertical support 3, and a first linear module arranged vertically is fixed to the vertical support 3. A lifting and fixing plate 702 is mounted on the first linear module. The adsorption component 9 and the locking component 7 are both fixed to the lifting and fixing plate 702.

[0055] like Figure 4 As shown, the adsorption assembly 9 includes a servo motor 901 for controlling the rotation of the ceramic suction nozzle 905. The output shaft of the servo motor 901 is connected to a buffer bracket via a coupling, and the ceramic suction nozzle 905 is fixed to the bottom of the buffer bracket. Rotation of the servo motor 901 controls the rotation of the buffer bracket, and the axis of the ceramic suction nozzle 905 is coaxial with the output axis of the coupling. Therefore, when the servo motor 901 rotates, the ceramic suction nozzle 905 only rotates and does not translate.

[0056] The buffer support includes a fixed support 906 and a sliding support 902. The fixed support 906 and the sliding support 902 are connected by a slide rail, and the sliding support 902 can slide up and down relative to the fixed support 906. Four first guide rods 903 are also provided between the sliding support 902 and the fixed support 906. The four first guide rods 903 are vertically arranged and slidably connected to the sliding support 902. Each sliding rod is fitted with a first spring 904, and both ends of the first spring 904 are fixedly connected to the fixed support 906 and the sliding support 902, respectively. The first springs 904 can be connected by welding to fix both ends of the first springs 904. A pressure sensor is also provided on the fixed support 906, located on the upper side of the sliding support 902. The ceramic suction nozzle 905 is fixed to the bottom of the sliding support 902. A pressure rod is provided on the upper side of the sliding bracket 902. When the sliding bracket 902 moves upward, the pressure rod will approach the pressure sensor. When the pressure rod contacts the pressure sensor, it will transmit the pressure of the ceramic nozzle 905 to the pressure sensor. The signal output terminal of the pressure sensor is connected to a controller, which controls the operation of the first linear module according to the pressure signal from the pressure sensor.

[0057] like Figure 1 and Figure 7 As shown, the lower platform 602 is also fixed with a lower-position lens 4, and the vertical bracket 3 is fixed with an upper-position lens 2. The horizontal position of the upper-position lens 2 is the same as that of the adsorption assembly 9. The upper-position lens 2 is used to capture the position of the clamping assembly 10 and transmit the captured image to the controller. The controller identifies and controls the movement of the ceramic suction nozzle 905, so that the optical device on the ceramic suction nozzle 905 is placed in the designated position of the clamping assembly 10. The lower-position lens 4 is used to capture the angle of the optical device from below. After the ceramic suction nozzle 905 adsorbs the optical device, the two-dimensional cross linear motor 1 controls the slide table 6 to move, moving the lower-position lens 4 to the lower side of the optical device. The lower-position lens 4 transmits the captured data to the controller, and the controller identifies the angle of the optical device. If the angle of the optical device does not meet the requirements, the buffer bracket is rotated by the servo motor 901 to make the angle of the optical device meet the requirements. After meeting the requirements, the two-dimensional cross linear motor 1 moves the clamping assembly 10 to the lower side of the optical device. The upper-position lens 2 is used to capture the position of the clamping assembly 10 and transmit the captured image to the controller. The controller recognizes and controls the slide 6 to adjust its horizontal position, and then controls the first linear module to descend so that the optical device on the ceramic nozzle 905 is placed on the designated position of the clamping assembly 10.

[0058] The upper platform 601 is also equipped with an optical device placement assembly. The optical device placement assembly includes a placement tray 8 and a placement slot 11. The placement slot 11 is used to position the placement tray 8, which is used to hold the optical devices. When processing is required, the operator places the placement tray 8 containing the optical devices into the placement slot 11. The bottom of the placement slot 11 is provided with suction holes for fixation by vacuum suction. The slide table 6 moves the placement tray 8 to the underside of the ceramic suction nozzle 905, which then suctions the optical devices and places them into the clamping assembly 10. Conversely, when the ceramic suction nozzle 905 removes the optical devices from the clamping assembly 10, they are also placed into the corresponding placement tray 8 for easy removal by the operator.

[0059] like Figure 5 and Figure 6 As shown, the locking assembly 7 includes a lifting structure, a lifting fixed plate 702, a lifting sliding plate 705, a Phillips head 704, a motor for driving the Phillips head 704, and a buffer 703. The lifting structure is fixed to the vertical support 3, and the lifting fixed plate 702 is fixedly connected to the lifting structure, with the lifting structure controlling the raising and lowering of the lifting fixed plate. A slide rail is provided between the lifting fixed plate 702 and the lifting sliding plate 705, allowing the lifting sliding plate 705 to slide up and down relative to the lifting fixed plate 702. A second guide rod 707 is provided between the lifting sliding plate 705 and the lifting fixed plate 702, and the second guide rod 707 is slidably connected to the lifting sliding plate 705. A second spring 706 is also provided on the second guide rod 707. The second spring 706 between the lifting fixed plate 702 and the lifting sliding plate 705 provides an initial pressure to the Phillips head 704, ensuring that the Phillips head 704 remains connected to the screw and preventing separation of the Phillips head 704 from the screw. The motors driving the Phillips head 704 are all fixed on the lifting sliding plate 705. The output shaft of the motor is vertically arranged and faces downward. The output shaft is equipped with a coupling. The Phillips head 704 is connected to the connecting shaft and located below the coupling, used to tighten or loosen the screw below. There are two buffers 703, located on both sides of the Phillips head 704. When the Phillips head 704 descends, the buffers 703 act as a buffer to prevent the Phillips head 704 from rigidly colliding with the screw. When the Phillips head 704 moves downward to tighten or loosen the clamping assembly 10, the buffers 703 first contact the clamping assembly 10, decelerating the Phillips head 704. Subsequently, the buffers 703 are gradually compressed, and the Phillips head 704 contacts the screw and begins to tighten it. The buffer 703 can be a pneumatic buffer 703 or a hydraulic buffer 703. Both pneumatic buffer 703 and hydraulic buffer 703 have the characteristic of long compression distance and will not obstruct the lifting and lowering of the Phillips head 704.

[0060] When the clamping assembly 10 is secured with a slotted screw, the other locking assembly 7 can secure the slotted screwdriver bit.

[0061] like Figure 15-21 As shown, the clamping assembly 10 includes an elastic clamp and a positioning structure. The elastic clamp is used to clamp and fix the optical device, including a base 1002 and a pressure block 1001. The pressure block 1001 is detachably mounted on the base 1002 by screws. The Phillips head screwdriver bit 704 is used to tighten and loosen the screws between the pressure block 1001 and the base 1002. The base 1002 is provided with several fixing slots 1003 for placing optical devices. A sliding groove 1007 is provided at one corner of any fixing slot 1003, and the sliding groove 1007 communicates with the side of the fixing slot 1003. Several elastic pressure plates 1004 are provided between the pressure block 1001 and the base 1002, and each sliding groove 1007 corresponds to one elastic pressure plate 1004. The elastic pressure plate 1004 abuts against the bottom surface of the pressure block 1001 from below, with the lower end of the elastic pressure plate 1004 located within the sliding groove 1007. As the pressure block 1001 presses down until its bottom surface contacts the top surface of the base 1002, all the elastic pressure plates 1004 deform under the action of the pressure block 1001. When the elastic pressure plate 1004 deforms, its bottom end slides into the fixing groove 1003, pressing the optical device placed in the fixing groove 1003 from the side.

[0062] The length direction of the slide groove 1007 and the length direction of the elastic pressure plate 1004 are in the same vertical plane. When the elastic pressure plate 1004 deforms, it will slide along the length direction of the slide groove 1007. The fixing groove 1003 is a rectangular groove with its opening facing upwards. The slide groove 1007 is inclined relative to the fixing groove 1003, and the connection point between the slide groove 1007 and the fixing groove 1003 is located at one corner of the fixing groove 1003. When the elastic pressure plate 1004 deforms and slides into the fixing groove 1003, it will enter the fixing groove 1003 from one corner.

[0063] like Figure 16 As shown, the pressure block 1001 has fixing grooves 1003 on both sides, and the fixing grooves 1003 on both sides of the pressure block 1001 are symmetrical with respect to the center of the pressure block 1001. When the pressure block 1001 is pressed down, the pressure on both sides of the pressure block 1001 is balanced, and the elastic pressure plates 1004 located on both sides are also balanced. The balanced force on the elastic pressure plates 1004 ensures that the optical device is fixed with balanced force, making the fixation of the optical device more stable.

[0064] The base 1002 includes a fixing block, a pad 1009, a perforated plate 1011, and a base plate 1012, which are stacked vertically. The perforated plate 1011 is located above the base plate 1012, the pad 1009 is located above the perforated plate 1011, and the fixing block is located above the pad 1009. A base plate 1010, which is connected to the elastic pressure plate 1004, is provided between the perforated plate 1011 and the pad 1009. The pressure block 1001, base plate 1010, fixing block, pad 1009, perforated plate 1011, and base plate 1012 are provided with positioning holes for positioning and fixing, and bolts or positioning pins are used to engage with the positioning holes for fixing and positioning.

[0065] The base 1002 has a chamfered corner 1015 structure at one corner, meaning that the fixing block, pad 1009, perforated plate 1011, and base plate 1012 all have chamfered corner 1015 structures at corresponding positions. The chamfered corner 1015 structure is used to fix the mounting positions of the fixing block, pad 1009, perforated plate 1011, and base plate 1012. The base plate 1010 is disposed between the pad 1009 and the perforated plate 1011, and a chamfered corner 1015 structure is also provided at the corresponding position on the base plate 1010.

[0066] like Figure 18 As shown, after removing the pressure block 1001, the fixing block is H-shaped, and the pressure block 1001 is connected to the middle of the fixing part. The thickness of the fixing block at the corresponding position of the pressure block 1001 is less than the thickness at both ends of the fixing block, and steps of different thicknesses are formed at the connection between the two ends and the middle of the fixing block. Positioning grooves 1005 and first positioning blocks 1006 of corresponding dimensions are machined at the connection between the steps and the fixing block. The positioning grooves 1005 and the first positioning blocks 1006 are used to position the pressure block 1001 and the fixing block in the horizontal plane. Positioning holes are provided at the corresponding positions of the pressure block 1001 and the fixing block, and the positions of the pressure block 1001 and the fixing block are fixed through the positioning holes.

[0067] like Figure 19 As shown, several elastic pressure plates 1004 are connected to a substrate 1010, and the elastic pressure plates 1004 and the substrate 1010 are integrally formed. That is, the elastic pressure plates 1004 are machined from both sides of the substrate 1010. The relative position of the machined elastic pressure plates 1004 and the substrate 1010 is accurate and reliable, and will not deform during use. The substrate 1010 is provided with positioning holes, and the positioning holes on the substrate 1010 correspond to those on the base plate 1012. When installing the elastic pressure plates 1004, it is only necessary to place the substrate 1010 in the corresponding position and use bolts and positioning pins for positioning. Therefore, the installation of the elastic pressure plates 1004 is faster and simpler, and can be completed in one operation.

[0068] A pad 1009 covers the substrate 1010. The pad 1009 is disposed on the upper side of the substrate 1010, and a perforated plate 1011 is disposed on the lower side. When the elastic pressure plate 1004 is deformed under pressure, the substrate 1010 will not deform along with the elastic pressure plate 1004 under the pressing action of the pad 1009 and the perforated plate 1011. The pad 1009 has an opening at the position corresponding to the elastic pressure plate 1004, so that the elastic pressure plate 1004 directly contacts the pressure block 1001.

[0069] The elastic pressure plate 1004 has an arc-shaped structure that curves upward in the middle. During the pressing process of the pressure block 1001, the bottom of the pressure block 1001 will contact the middle of the elastic pressure plate 1004. The pressure block 1001 presses the middle of the elastic pressure plate 1004, causing the lower end of the elastic pressure plate 1004 to slide into the fixing groove 1003 along the direction of the slide groove 1007, and press the optical device in the fixing groove 1003 tightly.

[0070] like Figure 17 and Figure 20 As shown, the bottom end of the elastic pressure plate 1004 is provided with a notch 1008. The notch 1008 has two mutually perpendicular sides, that is, two right-angled sides. The elastic pressure plate 1004 squeezes the optical device from the side through the two right-angled sides. Because the elastic pressure plate 1004 squeezes at an angle relative to the optical device, there will be significant pressure on both right-angled sides, squeezing and fixing the optical device from two directions.

[0071] The elastic pressure plate 1004 has two narrow portions 1013. The narrow portions 1013 are smaller in size compared to other locations on the elastic pressure plate 1004. For example, the width or thickness of the narrow portions 1013 is smaller than other locations. The substrate 1010 and the notch 1008 are located at opposite ends of the elastic pressure plate 1004, while the narrow portions 1013 are located near the substrate 1010 and near the notch 1008, respectively. The smaller size of the narrow portions 1013 makes them more prone to deformation under pressure, thus increasing elasticity.

[0072] like Figure 21As shown, the perforated plate 1011 has several through holes. When the perforated plate 1011 is connected to the base plate 1012, the bottom of the through holes is closed by the base plate 1012, thereby forming a fixing groove 1003 and a sliding groove 1007. In other words, the combination of the perforated plate 1011 and the base plate 1012 forms the fixing groove 1003 and the sliding groove 1007. By processing the through holes on different perforated plates 1011 into different shapes, replacing the perforated plate 1011 can form fixing grooves 1003 and sliding grooves 1007 of different shapes with the base plate 1012, thus adapting to optical devices of different sizes. The thickness of the perforated plate 1011 is the same as the depth of the fixing groove 1003 and the sliding groove 1007, and the thickness of the perforated plate 1011 is less than the thickness of the base plate 1012. Compared to directly processing the fixing groove 1003 and the sliding groove 1007 on the base plate 1012, the thickness of the perforated plate 1011 is thinner. When it is necessary to replace the fixed groove 1003 and the sliding groove 1007, replacing the orifice plate 1011 has the advantages of lower material cost and smaller size.

[0073] like Figures 10-14 As shown, the positioning structure includes a carrier disk 1018, a second positioning block 1016, an adsorption structure, and a platform plate. The carrier disk 1018 is used to fix a clamp, and the clamp is used to clamp optical devices. The adsorption structure is fixed to the bottom surface of the platform plate. The second positioning block 1016 is fixed to the top surface of the platform plate. The second positioning block 1016 has two mutually perpendicular right-angled surfaces, and the two right-angled surfaces are located on the side of the second positioning block 1016. The carrier disk 1018 is placed on the platform plate, and one corner of the carrier disk 1018 is in contact with the two right-angled surfaces of the second positioning block 1016. The corner where the carrier disk 1018 connects to the second positioning block 1016 is provided with a chamfer 1015. The second positioning block 1016 is provided with a fiber optic sensor 1017, which is used to detect the distance of the chamfer 1015 surface. A controller is also included. The output signal of the fiber optic sensor 1017 is transmitted to the controller, which identifies and processes the signal.

[0074] Each optical device corresponds to a specific fixture, and each fixture corresponds to a specific carrier disk 1018. The chamfer 1015 on each carrier disk 1018 has a different size. When the carrier disk 1018 is in contact with the two right-angled surfaces of the second positioning block 1016, the fiber optic sensor 1017 detects the distance of the chamfer 1015 and determines the optical device model corresponding to the carrier disk 1018 based on this distance. If the optical device model corresponding to the carrier disk 1018 matches, an electrical signal is sent indicating that the optical device model corresponding to the carrier disk 1018 is correct; if the optical device model corresponding to the carrier disk 1018 does not match, another electrical signal is sent indicating that the optical device model corresponding to the carrier disk 1018 is incorrect. The fiber optic sensor 1017 sends the electrical signal to the controller, which recognizes the electrical signal and controls whether the equipment for processing or gripping the optical device is started. When the optical device model corresponding to the carrier disk 1018 is correct, the processing or gripping equipment will be started; when the optical device model corresponding to the carrier disk 1018 is incorrect, the processing or gripping equipment will not be started.

[0075] The processing or gripping equipment may be a suction nozzle for absorbing light and other structures for controlling the movement of the suction nozzle. The controller may be a PLC or a microcontroller.

[0076] In another embodiment, an infrared sensor is used instead of the fiber optic sensor 1017 to measure the spacing of the chamfer 1015.

[0077] The top of the carrier tray 1018 is provided with a groove for placing elastic clamps and a locking screw for fixing the clamps. The locking screws pass through the side of the groove and tighten the clamps from the side. The top of the carrier tray 1018 is provided with multiple elastic clamps, which increases the number of optical devices that can be clamped at one time.

[0078] like Figure 12 As shown, the second positioning block 1016 is L-shaped, and the carrier plate 1018 is attached to the two inner sides of the L-shaped second positioning block 1016. The fiber optic sensor 1017 is disposed at the included angle of the second positioning block 1016. A first fixing hole 1022 for fixing the fiber optic sensor 1017 is provided at the included angle of the second positioning block 1016, and the fiber optic sensor 1017 is inserted into the hole. The second positioning block 1016 has a locking hole 1023, the axis of which is perpendicular to and intersects the axis of the first fixing hole 1022. The fiber optic sensor 1017 can be fixed by using a locking screw to engage with the locking hole 1023. The second positioning block 1016 is fixed to the platform plate by bolts or screws or other fasteners.

[0079] The included angle between the fiber optic sensor 1017 and the second positioning block 1016 corresponds, and the chamfer 1015 on the carrier disk 1018 is located at the connection point of the two sides that are in contact with the second positioning block 1016. The two sides of the carrier disk 1018 are in contact with the second positioning block 1016, and the fiber optic sensor 1017 detects the spacing of the chamfers 1015 on the carrier disk 1018. Increasing the dimensional difference of the chamfers 1015 on different carrier disks 1018 can reduce the required detection accuracy of the fiber optic sensor 1017, ensuring that even if there is a certain error in the detection result of the fiber optic sensor 1017, it will not affect the overall detection result.

[0080] In another embodiment, the chamfer 1015 can be replaced by a countersunk hole. Compared to machining a countersunk hole, the chamfer 1015 is easier to machine, and the machining process and cost of the carrier 1018 are lower.

[0081] like Figure 10 and Figure 13 As shown, the adsorption structure is an electromagnetic chuck assembly, and the carrier plate 1018 is made of a metal material that can be magnetically attracted, such as an iron carrier plate 1018. After the carrier plate 1018 is positioned with the second positioning block 1016, the electromagnetic chuck assembly is energized. The electromagnetic chuck assembly attracts and fixes the carrier plate 1018, accelerating the fixing speed of the carrier plate 1018. When it is necessary to remove the carrier plate 1018, the electromagnetic chuck assembly is de-energized, causing the electromagnetic chuck assembly to stop attracting. The electromagnetic chuck assembly has the advantages of high fixing efficiency and fast response speed, which can improve the fixing and disassembly efficiency of the carrier plate 1018. The electromagnetic chuck assembly is fixed to the bottom surface of the platform plate by fasteners such as bolts or screws. The magnetic force of the electromagnetic chuck assembly attracts the carrier plate 1018 through the platform plate. Setting the electromagnetic chuck assembly at the bottom of the platform plate can avoid the installation or removal of the electromagnetic chuck assembly affecting the accuracy of the top of the platform plate. The platform board has high precision at the top and the carrier plate 1018, which can ensure the positional accuracy of the fixture and the optical components on the fixture.

[0082] like Figures 13 to 14As shown, the electromagnetic chuck assembly includes a chuck bracket, an adjusting block 1019, and an electric chuck 1021. The adjusting block 1019 is mounted on the chuck bracket and has screws. The electric chuck 1021 has screw holes, and the screws engage with the screw holes. The electric chuck 1021 is fixedly connected to the adjusting block 1019 by screws. A stepped structure 1014 is provided in the middle between the chucks. The top of the stepped structure 1014 fits against the bottom of the platform plate, and the stepped structure 1014 is used to limit the position of the chuck bracket. The stepped structure 1014 is fixed to the platform plate by screws. The stepped structure 1014 increases the installation space for the adjusting column and the electric chuck 1021, and can effectively control the distance between the adjusting block 1019 and the carrier plate 1018.

[0083] The adjusting block 1019 is cylindrical in shape, and the suction cup bracket has an adjusting hole, within which the adjusting block 1019 is located. The suction cup bracket is equipped with a locking screw, and a locking screw hole 1026 is formed on the side wall of the adjusting hole. The locking screw engages with the locking screw hole 1026. The end of the locking screw presses against the adjusting block 1019 from the side, thus fixing the adjusting block 1019. Each adjusting hole has two locking screw holes 1026, and the axes of the two locking screw holes 1026 are perpendicular to each other. The two locking screws press against the adjusting block 1019 from both perpendicular sides, making the clamping effect more stable. When the locking screws are not tightened, the adjusting block 1019 can slide slidably connected to the adjusting hole. The electric suction cup 1021 is fixedly connected to the adjusting block 1019. Changing the position of the adjusting block 1019 along the axis of the adjusting hole changes the distance between the electric suction cup 1021 and the carrier plate 1018. The suction force of the electric suction cup 1021 on the carrier plate 1018 is controlled by adjusting the distance between the electric suction cup 1021 and the carrier plate 1018. When installing the adjusting block 1019, it can be inserted through the lower side of the adjusting hole and then fixed. The diameter of the electric suction cup 1021 is smaller than the diameter of the adjusting block 1019. Therefore, the electric suction cup 1021 and the adjusting block 1019 can be installed after the suction cup bracket is installed. After the suction cup bracket is installed, there is a more accurate reference point when installing the electric suction cup 1021 and the adjusting block 1019, making the installation and adjustment efficiency of the electric suction cup 1021 and the adjusting block 1019 higher. When using the electromagnetic chuck assembly, if one of the electric suction cups 1021 is damaged, the electric suction cup 1021 and the adjusting block 1019 can be removed from the lower side of the adjusting hole for replacement without disassembling the suction cup bracket, facilitating the maintenance of the electromagnetic chuck assembly.

[0084] like Figure 13As shown, four electric suction cups 1021 are provided, each corresponding to an adjusting block 1019. The four electric suction cups 1021 are evenly distributed on both sides of the stepped structure 1014. When the electromagnetic adsorption assembly 9 is working, the force on both sides of the step is uniform. A hole is provided on the side of each electric suction cup 1021, into which a limiting rod 1024 is inserted. When the electric suction cup 1021 rotates, the limiting rod 1024 rotates with it. When the end of the limiting rod 1024 rotates to the position of the stepped structure 1014, the end of the limiting rod 1024 will abut against the side of the stepped structure 1014, preventing the electric suction cup 1021 from rotating, thus limiting the rotation angle of the electric suction cup 1021. When the electric suction cup 1021 and the adjusting block 1019 are connected by screws, the limiting rod 1024 provides a reaction force to the electric suction cup 1021, allowing the screws to fix the adjusting block 1019 to the electric suction cup 1021. The limiting rod 1024 also prevents the electric suction cup 1021 from rotating and falling off during operation, ensuring that the electric suction cup 1021 is stably fixed to the adjusting block 1019.

[0085] In another embodiment, the adsorption structure can be a vacuum suction cup, with a vacuum pump connected to the vacuum suction cup via a pipe, the vacuum pump providing negative pressure to the vacuum suction cup. The vacuum suction cup is positioned on the upper side of the platform plate, directly adsorbing and fixing the bottom surface of the carrier plate 1018.

[0086] Compared to vacuum chucks, electromagnetic chuck assemblies have the advantages of requiring fewer parts and having a simpler structure. The adsorption effect of vacuum chucks is affected by airtightness; when there is air leakage at the connection between the vacuum chuck and the carrier plate 1018, the adsorption and fixation effect cannot be achieved. Therefore, the adsorption structure using electromagnetic chuck assemblies also has the advantage of higher stability.

[0087] The platform plate has a groove 1020 on its top surface, and the position of the groove 1020 corresponds to the position of the carrier plate 1018. The second positioning block 1016 is located on one side of the groove, and the two right-angled surfaces on the inner side of the second positioning block 1016 are respectively located in the same plane as the two side walls of the groove 1020. A suction cup through-hole is provided at the bottom of the groove 1020, and the top of the electric suction cup 1021 is located within the suction cup through-hole.

[0088] In another embodiment, the platform plate is a metal plate, and the magnetic force of the electromagnetic chuck assembly can be transmitted to the carrier plate 1018 through the platform plate, so that the carrier plate 1018 is stably connected to the platform plate.

[0089] like Figures 7-9As shown, the pressing assembly 5 includes a pressing arm 501, a steering cylinder 502, and an electric displacement stage 504. The electric displacement stage 504 has a vertical displacement direction and is used to control the raising and lowering of the pressing arm 501. A transition block is fixed to the lifting portion of the electric displacement stage 504, and the steering cylinder 502 is fixed to the transition block. One end of the pressing arm 501 is connected to the rotating portion of the steering cylinder 502. The rotating portion of the steering cylinder 502 rotates in the horizontal plane, and when the rotating portion of the steering cylinder 502 rotates, the pressing arm 501 also rotates accordingly.

[0090] In another embodiment, the electric displacement stage 504 can also be replaced by a lead screw and nut pair, with the pressure arm 501 fixed on the nut pair, and the rise and fall of the nut pair can be controlled by rotating the lead screw.

[0091] like Figure 7 As shown, the pressure arm 501 is located on the upper side of the elastic clamp. When it is necessary to clamp the elastic clamp to hold the product, the electric displacement stage 504 moves downward, and the pressure arm 501 presses down onto the pressure block 1001 of the elastic clamp, thereby clamping the pressure block 1001 of the elastic clamp. After the elastic clamp is clamped, it can be fixed with fasteners such as screws. When it is necessary to remove the product clamped on the elastic clamp, first remove the fasteners such as screws, then loosen the elastic clamp. The electric displacement stage 504 moves upward, and the pressure of the pressure arm 501 on the elastic clamp gradually decreases. Finally, the pressure arm 501 disengages from the elastic clamp and no longer exerts pressure on it. When the fasteners on the elastic clamp are removed, the pressure arm 501 remains pressed on the elastic clamp. Therefore, the elastic clamp will not bounce under the action of elastic force, nor will the product fall and be damaged due to the release of elastic force. The upward movement of the pressure arm 501 is a process of slow release of the elastic force of the elastic clamp. This allows the accumulated elastic force of the elastic clamp to be released slowly during the upward movement of the pressure arm 501, solving the problem of the pressure block 1001 bouncing due to the rapid release of elastic force when the elastic clamp is released. The elastic clamp and the electric displacement stage 504 are respectively fixed on two platforms. The elastic clamp is located on the upper platform 601, while the electric displacement stage 504 is fixed on the lower platform 602.

[0092] After the pressure arm 501 rises and disengages from the elastic clamp, the steering cylinder 502 begins to operate, moving the pressure arm 501 away from the upper side of the elastic clamp, allowing workers or other equipment to grip or place the elastic clamp and product from above. The rotating cylinder prevents the pressure arm 501 from obstructing the upper side of the elastic clamp. Since the rotating cylinder is located on one side of the elastic clamp, the rotation angle of the pressure arm 501 only needs to be controlled at approximately 90°. Therefore, a 90° steering cylinder 502 can be directly purchased.

[0093] like Figure 8As shown, the connecting block 503 has a symmetrical structure, with an upper connecting plate on the upper side for fixing the steering cylinder 502 and a lower connecting plate on the lower side for connecting the electric displacement stage 504. The upper connecting plate and the steering cylinder 502 can be fixedly connected by bolts or screws, and the lower connecting plate and the electric displacement stage 504 can be fixedly connected by bolts or screws. The cross-sectional dimension of the middle part of the connecting block 503 is smaller than the dimensions of the upper and lower connecting plates. That is to say, there is space for mounting screws on both the lower and upper sides of the upper connecting plate, which facilitates the connection of the upper connecting plate to the steering cylinder 502 and the lower connecting plate to the electric displacement stage 504.

[0094] like Figure 9 As shown, the pressure arm 501 includes a boom 507 and a urethane pressure block 1001. The urethane pressure block 1001 is elongated and fixed to the boom 507. The bottom of the urethane pressure block 1001 passes through the boom 507 and extends to the lower side of the boom 507. Therefore, when the pressure arm 501 presses down on the elastic clamps, the urethane pressure block 1001 comes into contact with the elastic clamps. The urethane pressure block 1001 deforms under pressure. When the pressure arm 501 needs to press down and position multiple parallel elastic clamps, even if the dimensional accuracy of the multiple parallel elastic clamps deviates, only the urethane pressure block 1001 will deform differently. Therefore, by setting the urethane pressure block 1001, the urethane pressure block 1001 can press and position multiple parallel elastic clamps, ensuring the stability of the pressing effect of the pressure arm 501 on multiple elastic clamps.

[0095] like Figure 9 As shown, the urethane pressure block 1001 has a raised structure 508 at its bottom, which passes through the middle of the arm 507. The bottom of the raised structure 508 passes through the arm 507 and protrudes from the bottom of the arm 507. When the pressure arm 501 presses down on the elastic clamps, the raised structure 508 contacts the elastic clamps. That is, when the pressure arm 501 presses down on the elastic clamps, the raised structure 508 is the contact point and the force point. The raised structure 508 is part of the urethane pressure block 1001, so the raised structure 508 will deform under force. When each elastic clamp is pressed into place, even if the height of the elastic clamps is different, it can be compensated by the deformation of the raised structure 508. Even if the height of the elastic clamps is different, under the sufficient pressure provided by the electric displacement stage 504, the raised structure 508 at the bottom of the pressure arm 501 can also press all the elastic clamps together by deformation.

[0096] In another embodiment, the urethane block 1001 can also be replaced by a rubber block.

[0097] like Figure 9As shown, a boss is provided at the end of the boom 507, and a second fixing hole 505 is provided at the boss. The boom 507 is connected to the rotating part of the steering cylinder 502 by a screw passing through the second fixing hole 505. When the urethane pressure block 1001 is fixed to the upper side of the boom 507, the top height of the urethane pressure block 1001 is the same as the height of the boss. The boss increases the axial length of the second fixing hole 505, increases the connection area with the rotating cylinder, and increases the stability of the connection between the boom 507 and the rotating cylinder. The top of the urethane pressure block 1001 is flush with the boss, making the shape of the pressure arm 501 more aesthetically pleasing.

[0098] The boom 507 has a slotted hole, the length of which is along the length of the boom 507. Screw holes for fixing urethane pressure blocks 1001 are provided at both ends of the slotted hole, allowing the two ends of the urethane pressure blocks 1001 to be fixed to the boom 507 with screws. When subjected to force, the portion of the urethane pressure block 1001 passing through the slotted hole can bend upwards at its center, increasing its deformability. The slotted hole, in conjunction with the urethane pressure block 1001, reduces the overall thickness of the boom 501. If urethane pressure blocks 1001 of the same thickness were directly stacked and fixed to the boom 507, the support provided by the boom 507 would reduce the deformability of the urethane pressure blocks 1001, increasing the overall thickness of the boom 501 and the space required for the entire device.
