[0002] In the automated production process of optical components, some workstations often use high-speed rotation to perform corresponding process processing on optical components. At this time, the optical components need to be clamped. The traditional low-speed rotation clamping method can adopt the method of clamping with air slip rings and pneumatic clamping claws, but the air slip ring cannot meet the clamping requirements during high-speed rotation. The traditional high-speed rotation clamping method generally adopts the method of manually placing the optical components into the positioning groove, and the side studs support the optical components to ensure that the optical components will not move or be thrown out. This method involves more actions during the clamping process, low efficiency, high labor costs, poor safety, many uncontrollable factors in manual clamping, and manual clamping can easily cause damage and destruction to the optical components. In order to solve the drawbacks of this clamping method, and to solve the problem of efficient and automatic clamping of optical components during high-speed rotation without being thrown out by centripetal force, the present invention adopts a new method to efficiently and stably complete the automatic clamping process.

[0028] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described in conjunction with specific embodiments and the accompanying drawings of the specification.

[0029] like Figure 1 and Figure 2 As shown, the technical solution of the present invention is a device clamping device, comprising a rotating spindle 4, a mounting base 1 fixedly mounted on the rotating spindle and driven by the rotating spindle and rotating around the axis of the rotating spindle 4, and a storage platform 2 and a clamping assembly 3 arranged on the mounting base 1. The clamping assembly 3 includes a plurality of clamping blocks 30, which are arranged outside the storage platform 2 and are centrally symmetrical with the axis of the rotating spindle 4.

[0030] like Figure 2 As shown, the side of the clamping block 30 facing the mounting base 1 is movably connected to the mounting base 1. A clamping shaft 31 perpendicular to the rotating main shaft 4 passes through the clamping block 30, and the clamping shaft 31 is fixedly installed with the mounting base 1.

[0031] The plane passing through the axis of the clamping shaft 31 and perpendicular to the rotating main shaft 4 is used as a dividing plane, and the dividing plane divides the clamping block 30 into a first part 32 and a second part 33, and the weight of the second part 33 is greater than the weight of the first part 32. The second part 33 is arranged close to the mounting base 1, and the first part 32 is located outside the placement surface 20 of the placement platform 2. The clamping block 30 rotates around the axis of the clamping shaft 31 as the mounting base 1 rotates, and the first part 32 and the second part 33 rotate close to and away from the placement platform 2 respectively.

[0032] Based on the above technical solution, in the automated production and processing of optical components, the optical components 100 to be processed are placed on the storage surface 20 of the storage platform, and then the driving device, such as a motor, is started to drive the rotating main shaft 4 to rotate, and the rotating main shaft 4 drives the mounting base 1 mounted thereon to rotate, and the mounting base 1 drives the storage platform 2 and the clamping assembly 3 mounted thereon to rotate synchronously around the axis of the rotating main shaft. After the clamping block 30 rotates, the clamping block 30 obtains centrifugal force (centrifugal force F=mω2r, m is the mass of the object, ω is the angular velocity, and r is the movement radius of the object). In addition, because the angular velocity and radius of rotation are fixed on the same clamping block, and the weight of the second part 33 is greater than the weight of the first part 32, the centrifugal force obtained by the first part is smaller than the centrifugal force obtained by the second part. In this way, the clamping block 30 can be regarded as a lever with the clamping shaft 31 as the fulcrum, and the force on the second part of the lever is greater than the force on the first part, so that the second part will move in the direction of the force, and the first part will move in the opposite direction of the force. Therefore, the first part 32 and the second part 33 rotate toward and away from the placement platform 2, respectively. According to the centrifugal force F=mω2r, that is, by adjusting the weight of the first part 32 or the second part 33, the clamping force of the first part 32 moving toward the placement platform 2 is adjusted, so that the first part 32 can be ensured to clamp the optical component 100 on the placement surface 20 of the placement platform 2. After the first part 32 moves toward the placement surface 20, the side of the optical component 100 applies an inward pressing force to the optical component, and the pressing forces of the symmetrically arranged first parts on the optical component are equal, so that the clamping of the optical component can be achieved and the balance of the optical component can be maintained.

[0033] Based on the above clamping method, there is no need to install clamps or perform locking operations during the clamping process. Clamping can be achieved after the storage platform is rotated, that is, automatic clamping and loosening are achieved. The clamping operation is simple and convenient, which effectively avoids tedious manual clamping operations and avoids problems such as insufficient clamping force followed by excessive clamping force due to manual operations.

[0034] Based on the above clamping method, based on the centrifugal force F=mω2r, after the weights of the first part and the second part are determined, and after the clamping block 30 is installed, the centrifugal force is proportional to the angular velocity ω of the rotation, that is, the faster the rotation, the greater the centrifugal force, that is, the greater the clamping force of the first part on the optical component 100. That is, when the rotation speed is high, the clamping is also reliable.

[0035] When the rotation stops, the rotation speed of the storage platform and the clamping block is slowly reduced to zero, so that the centrifugal force received by the clamping block is also slowly reduced, that is, the clamping force of the clamping block on the optical component is gradually reduced. Finally, the clamping block loses the centrifugal force because the rotation speed drops to zero, that is, the clamping block 30 is reset and loses the clamping force on the optical component, that is, the clamping block automatically relaxes the clamped optical component.

[0036] Based on the above technical solution, in the automated production and processing of optical components, the optical component 100 to be processed is placed on the placement surface 20 of the placement platform. The outer diameter of the placement surface 20 should be slightly smaller than the outer diameter of the optical component 100 placed thereon, so that the clamping block 30 can clamp the optical component 100, and avoid the problem that the clamping block 30 interferes with the outer edge of the placement surface 20 or is blocked by the placement surface 20 during clamping, resulting in the problem of being unable to clamp. The top surface of the clamping block 30 should be higher than the placement surface 20, and even higher than the top surface of the optical component 100, so as to avoid the problem that the optical component 100 moves due to inadequate clamping when the rotation is started, and the optical component 100 is not disengaged from the top of the clamping block.

[0037] Based on the above technical solution, the placement platform 2 can be rectangular or circular, and the optical component 100 placed on the placement platform 2 can be rectangular or circular. According to the calculation formula of centrifugal force F=mω2r, the weight (mass m) of the first part and the second part and the distance from the edge of the optical fiber component placed on the placement platform 2 are adaptively adjusted to adjust the size of the centrifugal force, so that the clamping force (extrusion force) of each clamping block on the optical component is equal, and the optical component can be clamped.

[0038] Based on the above technical solution, the best choice for the placement platform 2 and the optical component 100 is a circle, the axis of the rotating spindle 4 coincides with the axis of the placement platform 2, and each clamping block is installed at an equal distance outside the placement platform 2, making the overall device clamping device structure simpler.

[0039] In this technical solution, if Figure 2 As shown, the distance between the axis of the clamping shaft 31 and the side of the mounting base 1 facing the clamping block 30 is greater than the height of the second portion 33. A movable connection assembly is provided between the side of the clamping block 30 facing the mounting base 1 and the mounting base 1. The movable connection assembly realizes the movable connection of the clamping block 30, which facilitates the clamping block 30 to rotate around the clamping shaft 31 at an angle to achieve the clamping of the optical component 100. After the clamping shaft 31 is installed, the installation position of the clamping block 30 is determined, so that the movable support of the clamping block 30 is realized by the movable connection assembly, which facilitates the rotation of the clamping block 30 and avoids the problem of interference between the clamping block 30 and the side of the mounting base 1 facing the clamping block when the clamping block 30 rotates.

[0040] In this technical solution, if Figure 2As shown, the movable connection assembly includes a first connection hole 35 provided on the mounting base 1 and a connection pin 34 provided on the side of the second part 33 facing the mounting base 1. The connection pin 34 is parallel to the rotating spindle 4 and inserted into the first connection hole 35. The outer diameter of the connection pin 34 is smaller than the inner diameter of the first connection hole 35 and the connection pin 34 swings in the first connection hole 35 as the clamping block 30 rotates. The connection pin 34 will not interfere with the first connection hole 35, so that the clamping block 30 can rotate freely.

[0041] In this technical solution, if Figure 2 As shown, the clamping block 30 is provided with a second connection hole on the side facing the mounting base 1, and the connection pin 34 is placed in the second connection hole and is sleeved with a support spring 36. The other end of the support spring 36 extends into the second connection hole and abuts against the bottom of the second connection hole. The length of the connection pin is less than the sum of the depths of the first connection hole 35 and the second connection hole, and greater than the depth of the first connection hole 35, and the clamping shaft 31 is located between the support spring 36 and the storage platform. On the one hand, the clamping block 30 installed through the clamping shaft 31 is supported by the support spring 36, ensuring the balance of the clamping block, and preventing the clamping block from swinging or rotating outward at will when not clamped. On the other hand, the support spring applies a support force to the clamping block, so that when the clamping block is not rotating, the clamping block 30 will rotate around the clamping shaft 31 toward the storage platform side under the thrust of the support spring 36, so that the first part of the clamping block is close to the optical component, so as to effectively ensure the limit of the optical component, and avoid the problem of optical component offset or optical component movement during rotation. That is, when the speed of the clamping block is zero, the clamping block can also apply a certain clamping force to the optical components on the storage platform. When not rotating, the clamping block 30 will rotate around the clamping axis 31 toward the storage platform under the thrust of the support spring 36 to ensure that the components on the storage platform are clamped to a certain extent. After the rotation starts, the clamping block, under the joint action of the support spring and the centrifugal force, causes the first part to continue to move inward to achieve the clamping of the optical components, ensuring that the clamping block clamps the optical components smoothly. When the rotation starts or stops, due to the setting of the support spring 36, the first part maintains a certain clamping force and automatic limit on the optical components.

[0042] In this technical solution, a counterweight screw hole 37 is provided on the second part 33. A screw is screwed into the counterweight screw hole 37 to increase the weight of the second part, change the centrifugal force of the second part, and adjust the clamping force (extrusion force) of the optical component.

[0043] In the present technical solution, three clamping blocks 30 are provided, and are centrally symmetrically arranged with respect to the axis of the rotating spindle 4. The central angle between two adjacent clamping blocks 30 is 120°, and the clamping is reliable, avoiding the excessive number of clamping blocks 30 that would cause the device structure to be complicated, while ensuring effective clamping of the optical components.

[0044] In the present technical solution, the side of the clamping block 30 facing the placement platform 2 is set as a concave arc surface, and the contact surface between the concave arc surface and the optical component is increased to ensure effective clamping.

[0045] like Figure 1 and Figure 2 As shown, a device clamping method of the technical solution of the present invention adopts the aforementioned device clamping device for clamping. The device 100 to be clamped is placed on the placement surface 20 of the rotating placement platform 2; the placement platform 2 and the clamping block 30 rotate synchronously, the clamping block 30 obtains centrifugal force, the first part 32 and the second part 33 both rotate around the clamping axis 31, the second part 33 rotates away from the placement platform 2, and the first part 32 rotates close to the placement surface 20, clamping the device to be clamped on the placement surface 20.

[0046] like Figure 4 and Figure 5 As shown, a device installation apparatus of the technical solution of the present invention includes the aforementioned device clamping device, a pick-and-place robot for picking up and placing devices (optical components 100) on the storage platform 2, and an avoidance drive structure for driving the first part 32 of the clamping block 30 to move away from the storage platform 2.

[0047] like Figure 4 The pick-and-place robot comprises a Z-direction motion module 90 which is parallel to the rotating spindle 4 and moves along the axis direction of the rotating spindle 4, and an automatic robot assembly 91 arranged on the Z-direction motion module 90. The Z-direction motion module 90 is connected to an X / Y axis motion module, and the X / Y axis motion module drives the Z-direction motion module 90 and the automatic robot assembly 91 to move along the X / Y axis direction as a whole.

[0048] The avoidance driving structure includes a clamping block opening and closing pin 51 fixed on the side of the clamping block 30 away from the mounting base 1 and a push plate 92 that applies an outward thrust to the clamping block opening and closing pin 51. The push plate 92 is arranged parallel to the side of the clamping block 30 away from the mounting base 1 and is fixed to the front end of the Z-direction motion module 90 through a cylinder. A wedge groove 93 adapted to the clamping block opening and closing pin 51 is arranged on the side of the push plate 92 facing the clamping block 30. The wedge groove 93 includes a wedge surface 94 that pushes the clamping block opening and closing pin 51 outward.

[0049] The push plate 92 is also provided with an avoidance groove 95 facing the storage platform 2, and the radius of the avoidance groove 95 is greater than the distance from the inner side of the clamping block 30 to the axis of the rotating spindle 4. The automatic manipulator assembly 91 extends from the avoidance groove 95 to pick and place the device on the storage platform 2.

[0050] Based on the above technical solution, the X / Y axis motion module, the Z direction motion module 90 and the automatic manipulator assembly 91 can adopt any structure in the prior art that can meet the requirements of the technical solution. The specific structure is not explained and limited here. The specific structure of the X / Y axis motion module, the Z direction motion module 90 and the automatic manipulator assembly 91 is not the technical core of the technical solution. The general automatic manipulator assembly 91 has several basic actions of opening and clamping, and is driven by the Z direction motion module 90 to move along the Z direction. The X / Y axis motion module drives the Z direction motion module 90 and the automatic manipulator assembly 91 to move along the X axis or Y axis as a whole.

[0051] The device installation apparatus in this technical solution has the following installation process:

[0052] In the first step, the X / Y axis motion module works to move the Z direction motion module 90 and the automatic manipulator assembly 91 to the material picking position; then the Z direction motion module 90 works to extend the automatic manipulator assembly 91 from the avoidance groove 95 of the push plate 92 and clamp it to the device to be installed (the optical component 100 to be installed), and then the X / Y axis motion module works to drive the Z direction motion module 90 and the automatic manipulator assembly 91 to move to the position facing the storage platform. Then the cylinder 96 connected to the Z direction motion module 90 works, and the cylinder 96 drives the push plate 92 to be pushed out along the Z direction until the push plate position exceeds the position of the automatic manipulator assembly 91, and then the cylinder stops working, as shown in FIG. Figure 4 shown.

[0053] In the second step, the Z-direction motion module 90 works, driving the cylinder 96, the push plate 92, the automatic manipulator assembly 91, and the device to be installed clamped on the automatic manipulator assembly 91 to move along the Z direction. First, the push plate 92 presses against the clamping block 30. At this time, the wedge groove 93 on the push plate 92 presses against the clamping block opening and closing pin 51 on the clamping block 30. As the Z-direction motion module 90 continues to work, first the first part 32 of the clamping block 30 rotates outward, and at the same time moves along the Z direction toward the fixed base side. As the push plate moves, the clamping block 30 first opens into place to expose the placement surface, and then the Z-direction motion module 90 drives the push plate 92 and the automatic manipulator assembly 91 to continue to move. The clamping block, the movable base, and the limit block 61 are continued to be pushed by the push plate until the optical component 100 to be installed clamped on the automatic manipulator assembly 91 reaches the placement surface 20. Then the Z-direction motion module 90 stops working. Figure 5 shown.

[0054] In the third step, the automatic robot assembly 91 is opened, and the optical component 100 to be mounted, which is clamped by the automatic robot assembly 91 , is placed on the placement surface 20 .

[0055] In the fourth step, the Z-direction motion module 90 drives the push plate 92 and the automatic manipulator assembly 91 to reset along the Z direction. During the reset process of the push plate 92, as the push plate retracts, the movable base and the limit block 61 are first lifted and reset to the highest position, and then the push plate continues to retract, the clamping block opening and closing pin 51 on the clamping block gradually disengages from the wedge groove 93 on the push plate 91, and the clamping block 30 moves toward the side of the placement surface 20 along the Z direction, that is, the clamping block 30 is reset to the outside of the placement surface 20. When the push plate 92 completely withdraws from the clamping block opening and closing pin 51, the clamping block 30 rotates and resets to clamp the optical components on the placement surface 20. At this time, the clamping block has an initial clamping force on the optical components on the placement surface 20 to prevent the optical components on the placement surface 20 from being offset or falling out.

[0056] When removing the optical components from the storage platform 20, the operation process is basically the opposite of the above installation process. First, the cylinder pushes the push plate 92 to the bottom position of the automatic manipulator assembly 91, and then the Z-direction motion module 90 drives the push plate and the automatic manipulator assembly 91 to move along the Z direction as a whole. When the push plate moves to the clamping block 30, the wedge surface 94 pushes the clamping block opening and closing pin 51 to move outward, and the clamping block 30 leaves the storage surface along the Z direction, and the first part 32 rotates outward at the same time, exposing the optical components 100 on the storage surface 20 of the storage platform 2. Then, the Z-direction motion module 90 drives the push plate and the automatic manipulator assembly 91 to continue to move along the Z direction as a whole until the automatic manipulator assembly 91 contacts the optical components on the storage surface. The Z-direction motion module 90 stops, and then the automatic manipulator assembly 91 clamps the optical components 100 on the storage surface 20. After that, the Z-direction motion module 90 drives the automatic manipulator assembly 91 and the push plate 92 to reset along the Z direction as a whole and evacuate the storage platform.

[0057] Based on the above technical solution, by providing the push plate 92 and the clamping block opening and closing pin 51, the clamping block 30 is automatically opened, the operation is simple and reliable, and the fully automated operation of optical component installation is realized.

[0058] In this technical solution, if Figure 2As shown, the mounting base 1 includes a fixed base 11 fixedly connected to the rotating main shaft 4 and a movable base 12 sleeved on the outside of the storage platform 2. The fixed base 11 and the movable base 12 are arranged along the axial direction of the rotating main shaft 4. The fixed base 11 and the movable base 12 are connected by a Z-direction T-shaped guide column 13. The Z-direction T-shaped guide column 13 is fixedly connected to the fixed base 11 by a connecting screw 14, and the large end of the Z-direction T-shaped guide column 13 passes through the movable base 12. On the one hand, the Z-direction T-shaped guide column 13 realizes the relative fixation of the fixed base 11 and the movable base 12, avoiding the relative rotation between the movable base 12 and the fixed base 11 when the mounting base 1 rotates, that is, avoiding the movable base 12 from spinning; on the other hand, the Z-direction T-shaped guide column 13 also realizes the guidance and limitation of the movable base in the Z-direction movement. The clamping assembly 3 is placed on the side of the movable base 12 away from the fixed base 11.

[0059] like Figure 2 A Z-direction guide shaft 15 coaxial with the rotating main shaft is fixedly connected to the fixed base 11, the movable base 12 is sleeved on the Z-direction guide shaft 15, and a Z-direction guide sleeve 16 is provided between the movable base 12 and the Z-direction guide shaft 15. The movable base 12 is fixedly connected to the Z-direction guide sleeve 16, and both slide along the Z-direction guide shaft driven by the push plate 92.

[0060] In this technical solution, if Figure 3 As shown, the avoidance driving structure that drives the first part 32 of the clamping block 30 to move away from the storage platform 2 also includes a clamping block moving component. The clamping block moving component is arranged between the sides opposite to the movable base 12 and the fixed base 11. The clamping block moving component includes a guide column 83 that is parallel to the rotating main shaft 4 and fixedly connected to the fixed base 11. The top of the guide column 83 penetrates the movable base 12, and a movable telescopic spring 82 is sleeved on the guide column 83. The movable telescopic spring 82 is placed between the movable base 12 and the fixed base 11 to achieve the reset of the movable base 12. A guide hole 81 is arranged on the side of the movable base facing the fixed base. The movable telescopic spring 82 and the guide column 83 both extend into the guide hole 81. When the push plate pushes the clamping block 30 downward, the movable base 12 compresses the movable telescopic spring 82 to move. After the push plate is withdrawn, the movable telescopic spring 82 is reset, pushing the movable base 12 to reset, that is, the clamping block 30 is reset.

[0061] In this technical solution, if Figure 3As shown, a limit block 61 is provided between two adjacent clamping blocks 30, and the limit block 61 is fixed on the side of the movable base 12 away from the fixed base 11. The side of the limit block 61 facing the storage platform 2 is located at the rear side of the side of the first part 32 facing the storage platform 2, and an axial hole 71 is provided on the side of the limit block 61 facing the clamping block 30, and the two ends of the clamping shaft 31 are respectively inserted into the axial holes 71 on the limit block 61. The setting of the limit block 61, on the one hand, facilitates the installation of the clamping shaft 31, that is, facilitates the installation of the clamping block 30, and on the other hand, provides a limit for the optical components placed on the storage platform 2 to prevent the optical components from falling off the storage platform when the clamping block fails. When the push plate 92 pushes the clamping block to move along the Z direction, the limit block 61 moves synchronously with the movable base 12 fixed to the clamping block 30.
