Description

Technical Field

[0001] The present invention relates to the technical field of material taking of floodlights, and specifically to an automatic material taking device for floodlight processing. Background Art

[0002] As a core device in modern lighting projects, the optical performance of floodlights highly depends on the precision processing and assembly of lens components. As the core component for optical path control, the surface accuracy of the lens directly affects key technical indicators such as spot uniformity and glare control. Especially the wide application of arc-shaped lenses (such as aspherical lenses) poses higher requirements for the picking and placing operations during the processing - accurate positioning needs to be achieved while ensuring the integrity of the curved surface.

[0003] First of all, the traditional device for clamping lenses, the general mechanical claw, clamps the arc-shaped lens through point contact or line contact, which is prone to stress concentration at the contact points. When the rigid claw contacts the lens surface, the pressure in the contact area can reach 3 - 5 times the material yield strength. For lenses made of glass or resin, this local stress concentration will induce the propagation of microcracks;

[0004] Most existing mechanical claws adopt a fixed clamping angle design and are difficult to adapt to lenses with different curvature radii. When the deviation between the curvature of the clamping surface and the preset clamping trajectory exceeds 0.5 mm, the contact area decreases by more than 40%, resulting in significant fluctuations in the clamping force.

[0005] Secondly, when using vacuum adsorption, most existing vacuum suction cups are designed for flat surfaces. When applied to concave and convex curved surfaces, uneven adsorption force distribution is likely to cause detachment, and there may be residual particles on the adsorption contact surface, forming scratches on the optical surface of the lens;

[0006] When the suction cup contacts the curved surface, the edge sealing ring forms a discontinuous contact with the lens surface, resulting in an increase in the leakage rate of the negative pressure cavity;

[0007] When the suction cup material contacts the lens, interfacial friction will generate polymer debris with a particle size of 0.5 - 5 μm. These particles will scratch the coating layer during repeated clamping.

[0008] Based on the above problems, it is necessary to develop a new clamping mechanism for lens clamping equipment with adaptive curved surface fitting, stress uniform distribution characteristics, and reduced contact contamination. Summary of the Invention

[0009] The purpose of the present invention is to provide an automatic material taking device for floodlight processing to solve the problems raised in the above background art.

[0010] To solve the above technical problems, the present invention provides the following technical solution: An automatic material taking device for floodlight processing, comprising:

[0011] A housing with a limiting block fixed on its outer side. A limiting shaft is slidably arranged in the limiting block, and a second sensor is provided at the lower end of the limiting shaft;

[0012] A gas exchange tube integrally formed with the housing;

[0013] A negative pressure clamping part arranged in the gas exchange tube, including a negative pressure tube, a micro vacuum pump fixed on the negative pressure tube, and a suction cup arranged at the lower end of the negative pressure tube. A first sensor is provided at the lower end of the suction cup;

[0014] A first cover plate and a second cover plate arranged at the upper end of the housing. An air pressure control part is arranged between the two. The air pressure control part includes a servo motor and a rotatable control frame plate. An air exchange hole is opened on the control frame plate;

[0015] The first sensor is used to trigger the forward suction of the micro vacuum pump, and the second sensor is used to control the forward and reverse start and stop of the servo motor and the reverse suction of the micro vacuum pump.

[0016] Further, the micro vacuum pump has two independent pump chambers. The negative pressure tube is sleeved in the gas exchange tube, and its outer wall is closely attached to the inner wall of the gas exchange tube.

[0017] Further, the control frame plate is meshed with the gear of the servo motor. An air exchange hole is opened on the first cover plate. The coincidence or dislocation of the air exchange hole and the gas exchange hole is realized by the rotation of the control frame plate to adjust the air pressure in the gas exchange tube.

[0018] Further, the first cover plate is also provided with an electric AC hole and an air flow hole. A sealing block is embedded in the electric AC hole. An electric connection wire is fixed on the outer side of the micro vacuum pump. The electric connection wire penetrates through the sealing block and is connected to an external circuit. An air flow tube is fixed on the outer side of the micro vacuum pump. The air flow hole is communicated with the micro vacuum pump through the air flow tube.

[0019] Further, an annular inner cavity is arranged inside the suction cup, and its material can be deformed to fit the lens curved surface.

[0020] Further, the position of the limiting shaft on the limiting block is linked with the vertical movement of the gas exchange tube to fix the position of the negative pressure clamping part in the gas exchange tube.

[0021] Further, a plurality of first sensors are circumferentially distributed at the lower end of the suction cup, and all the plurality of first sensors need to be pressed before the micro vacuum pump can be triggered.

[0022] Further, the air flow tube is made of threaded elastic metal material.

[0023] Further, a controller is also installed on the outer side of the casing, and the first sensor, the second sensor, the micro vacuum pump and the servo motor are all signal-connected to the controller.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention realizes the dynamic matching of the contact surface and the lens curvature through the sliding freedom degree of multiple independent negative pressure clamping parts on the gas exchange pipe. At the same time, by controlling the amount of gas inside the gas exchange pipe, the multiple independent negative pressure clamping parts are limited at different positions, fixing the matching of the contact surface and the lens curvature, and effectively eliminating the risk of microcrack generation.

[0025] By using a micro vacuum pump and a suction cup, each micro vacuum pump has an adsorption effect, adsorbing different positions of the lens surface, which not only ensures the adsorption stability, but also avoids scratches on the lens surface caused by uneven and excessive adsorption pressure on the lens surface, and also avoids causing detachment. Even if there are residual particles on the adsorption contact surface, the damage to the lens surface will be minimized under the action of the suction cup.

[0026] The gas exchange pipe cooperates with the negative pressure clamping part, so that the negative pressure clamping part contacts the lens, and the negative pressure clamping part generates a relative upward movement along the gas exchange pipe, making there be a certain resistance to the upward movement of the negative pressure clamping part, realizing the suction cup fitting the lens, and the adsorption is faster and more reliable.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1-9 , the present invention provides a technical solution: The traditional device for clamping a lens is a general mechanical claw that clamps the arc lens through point contact or line contact, which is prone to stress concentration at the contact point, and this kind of local stress concentration will induce the expansion of microcracks; in addition, when using vacuum adsorption, most of the existing vacuum suction cups are designed for flat surfaces. When applied to concave and convex curved surfaces, the uneven distribution of the adsorption force is likely to cause detachment, and there may be residual particles on the adsorption contact surface, forming scratches on the optical surface of the lens. Based on this, an automatic material taking device for spotlight processing is proposed, including:

[0040] A housing 1, on the outside of which a limit block 7 is fixed. A limit shaft 8 is slidably arranged in the limit block 7. A second sensor 81 is provided at the lower end of the limit shaft 8. The limit shaft 8 can move along the limit block 7, and the position of the limit shaft 8 can be adjusted to correspond to different lenses, so as to realize the contact between the limit shaft 8 and the platform during clamping, and realize the limitation of the negative pressure clamping part 3;

[0041] A gas exchange pipe 2 integrally formed with the housing 1, and the gas exchange pipe 2 is located inside the housing 1;

[0042] A negative pressure clamping part 3 arranged in the gas exchange pipe 2, including a negative pressure pipe 31, a micro vacuum pump 32 fixed on the negative pressure pipe 31, and a suction cup 36 arranged at the lower end of the negative pressure pipe 31. A first sensor 362 is provided at the lower end of the suction cup 36;

[0043] The first cover plate 4 and the second cover plate 5 are arranged at the upper end of the housing 1. The first cover plate 4 is fixed on the housing 1, and the second cover plate 5 is fixed on the first cover plate 4. An air pressure control part 6 is arranged between them. The air pressure control part 6 includes a servo motor 61 and a rotatable control frame plate 62. An air exchange hole 63 is formed on the control frame plate 62. The servo motor 61 is detachably installed on the first cover plate 4, and the rotatable control frame plate 62 is clamped on the first cover plate 4.

[0044] The first sensor 362 is used to trigger the forward suction of the micro vacuum pump 32, and the second sensor 81 is used to control the forward and reverse start and stop of the servo motor 61 and the reverse suction of the micro vacuum pump 32. When clamping, the first sensor 362 drives the micro vacuum pump 32 to work, so that the negative pressure clamping part 3 presents a negative pressure to adsorb the lens. The second sensor 81 will contact the plane where the lens is placed, drive the servo motor 61 to work in the forward direction, and make the control frame plate 62 rotate, so that the air exchange hole 63 is misaligned with the gas exchange hole 43, so as to fix the position of the negative pressure clamping part 3 and avoid up and down telescoping. When unloading, the second sensor 81 will contact the plane where the lens is placed again, drive the servo motor 61 to work in the reverse direction, and realize the communication between the air exchange hole 63 and the gas exchange hole 43, so that multiple negative pressure clamping parts 3 move downward under the action of gravity and are in the same horizontal state, so as to realize subsequent clamping. In addition, the reverse suction of the micro vacuum pump 32 is used to separate the lens from the suction cup 36.

[0045] Specifically, the automatic material taking device for floodlight processing includes a housing 1, a gas exchange pipe 2 and a negative pressure clamping part 3. When the suction cup 36 of the negative pressure clamping part 3 contacts the lens, multiple first sensors 362 are pressed, triggering the micro vacuum pump 32 to pump air to form negative pressure adsorption. Then, the second sensor 81 at the lower end of the limit shaft 8 will contact the platform. The air pressure control part 6 at the upper end of the housing 1 drives the control frame plate 62 to rotate through the servo motor 61, so that the air exchange hole 63 is misaligned with the gas exchange hole 43 to close the gas exchange pipe 2, maintaining the stability of the negative pressure clamping part 3, making the relative height positions of different negative pressure clamping parts 3 different, and the lower suction cup 36 fitting the lens. When discharging, after the second sensor 81 at the lower end of the limit shaft 8 contacts the platform, the servo motor 61 drives the control frame plate 62 to rotate in the reverse direction, the air exchange hole 63 is communicated with the gas exchange hole 43, and the gas exchange pipe 2 can intake and exhaust air, and the micro vacuum pump 32 inflates in the reverse direction to unload the lens.

[0046] The micro vacuum pump 32 has two independent pump cavities. The negative pressure pipe 31 is sleeved inside the gas exchange pipe 2, and its outer wall is closely attached to the inner wall of the gas exchange pipe 2.

[0047] Specifically, the double independent pump chambers of the micro vacuum pump 32 are internally connected to the negative pressure pipe 31, enabling air intake and exhaust. When the negative pressure pipe 31 moves up and down along the gas exchange pipe 2, it can intake and exhaust air from the space at the upper end of the negative pressure pipe 31 through the gas exchange holes 43. In the case where the gas exchange holes 43 are blocked, the position of the negative pressure pipe 31 is also limited. When the automatic lens feeding device for spotlight processing transports the lens, multiple negative pressure clamping parts 3 are at different heights to fit the lens, and the multiple negative pressure clamping parts 3 are kept fixed, so that each of the multiple negative pressure clamping parts 3 has the force to transport the lens, realizing the application of the force to transport the lens at multiple points. The suction cup 36 has a relatively large adsorption force area when adsorbing the lens, ensuring that the adsorption force is evenly distributed and easy to avoid causing detachment. Even if there are residual particles on the adsorption contact surface, the large adsorption area will not form scratches on the optical surface of the lens.

[0048] The control frame plate 62 meshes with the gear of the servo motor 61. Gas exchange holes 43 are provided on the first cover plate 4. The coincidence or misalignment of the ventilation holes 63 and the gas exchange holes 43 is realized by the rotation of the control frame plate 62 to adjust the air pressure in the gas exchange pipe 2, so that the gas exchange pipe 2 is in a closed or open state.

[0049] Specifically, the control frame plate 62 is rotatably installed at the upper end of the first cover plate 4. The servo motor 61 can be controlled by the second sensor 81 to rotate in the forward and reverse directions, realizing the coincidence or misalignment of the ventilation holes 63 and the gas exchange holes 43. When clamping the lens, the second sensor 81 controls the servo motor 61 to rotate forward, realizing the misalignment of the ventilation holes 63 and the gas exchange holes 43. When placing the lens, the second sensor 81 controls the servo motor 61 to rotate in reverse, realizing the coincidence of the ventilation holes 63 and the gas exchange holes 43, so as to complete the contact between the multiple negative pressure clamping parts 3 and the lens with different arc surfaces. After the lens is clamped and lifted, each negative pressure clamping part 3 has a pulling force, and the force applied to clamp the lens is uniform.

[0050] The first cover plate 4 is also provided with an electric AC hole 41 and an air flow hole 42. A sealing block 35 is embedded in the electric AC hole 41. An electric connection wire 34 is fixed on the outside of the micro vacuum pump 32. The electric connection wire 34 penetrates through the sealing block 35 and is connected to an external circuit. An air flow pipe 33 is fixed on the outside of the micro vacuum pump 32. The air flow hole 42 is connected to the micro vacuum pump 32 through the air flow pipe 33;

[0051] Specifically, the electric AC hole 41 is used for the penetration of the electric connection wire 34, enabling the micro vacuum pump 32 to operate. The sealing block 35 blocks the electric AC hole 41 to ensure that the inside of the gas exchange pipe 2 can be in a closed state. The air flow pipe 33 is connected to the micro vacuum pump 32, and the outer end of the air flow pipe 33 is fixed to the first cover plate 4, so that the gas generated by the operation of the micro vacuum pump 32 can be exhausted or introduced, changing the air pressure inside the negative pressure clamping part 3 to realize the picking and placing of the lens.

[0052] The suction cup 36 is fixed to the lower end of the negative pressure tube 31. An annular inner cavity 361 is provided inside the suction cup 36, and its material can be deformed to fit the lens surface. The suction cup 36 is fixedly arranged with the negative pressure tube 31, and when the lower end of the suction cup 36 is squeezed, it will deform.

[0053] Specifically, before clamping, the negative pressure clamping part 3 moves down to the lowest end along the gas exchange tube 2 under the action of gravity. After that, when clamping the lens, it is located at the upper end of the lens and presses the lens downward. The aperture of the gas exchange hole 43 is relatively small, which affects the discharge of the gas in the gas exchange tube 2. Therefore, when the negative pressure clamping part 3 clamps downward, while moving upward, a certain pressure is applied to the lens to realize the extrusion between the suction cup 36 and the lens. At the same time, due to the provision of the annular inner cavity 361, the annular inner cavity 361 deforms under force, ensuring that the suction cup 36 uniformly fits the lens surface, ensuring that the sealing ring at the edge of the suction cup 36 forms continuous contact with the lens surface, avoiding the leakage of the gas inside the negative pressure tube 31, completing the clamping. At the same time, the suction cup 36 is prone to deformation, and it also reduces the probability of the suction cup 36 particles scratching the coating layer during repeated clamping. The annular inner cavity 361 enables the suction cup 36 to adapt to the lens curvature and avoid local stress concentration.

[0054] The position of the limit shaft 8 on the limit block 7 is linked to the vertical movement of the gas exchange tube 2 to fix the position of the negative pressure clamping part 3 inside the gas exchange tube 2.

[0055] Specifically, when clamping the lens, the second sensor 81 will contact the platform, causing the air exchange hole 63 to be misaligned with the gas exchange hole 43, realizing the fixation of the position of the negative pressure clamping part 3. When unloading the lens, the second sensor 81 will also contact the platform, causing the air exchange hole 63 to communicate with the gas exchange hole 43, enabling the negative pressure clamping part 3 to slide downward along the gas exchange tube 2, and at the same time driving the reverse intake of the micro vacuum pump 32 to make the gas enter the negative pressure clamping part 3 to unload the lens.

[0056] A plurality of first sensors 362 are circumferentially distributed at the lower end of the suction cup 36, and the micro vacuum pump 32 can be triggered only after all the plurality of first sensors 362 are pressed. The plurality of first sensors 362 are embedded in the lower end of the suction cup 36 to avoid affecting the generation of a gap between the suction cup 36 and the lens. The second sensor 81 is also embedded in the lower end of the limit shaft 8 to enable the second sensor 81 to make sensitive contact.

[0057] Specifically, when all the first sensors 362 of the suction cup 36 detect the contact pressure, the double-pump chamber micro vacuum pump 32 works, avoiding directly making the micro vacuum pump 32 work when the suction cup 36 is not adsorbed, resulting in wasted work and reducing energy consumption to a certain extent.

[0058] The air flow pipe 33 is made of threaded elastic metal. The air flow pipe 33 is located inside the gas exchange pipe 2. Since the inside of the gas exchange pipe 2 needs to be in a closed or open state, it is easy for the air flow pipe 33 to be deformed under the influence of the internal air pressure of the gas exchange pipe 2. Therefore, setting the metal material can avoid deformation. The metal material is copper or stainless steel. The threaded and elastic air flow pipe 33 can cause the air flow pipe 33 to deform. When the negative pressure pipe 31 moves up and down along the gas exchange pipe 2, it ensures that the air flow pipe 33 remains stable and avoids breakage.

[0059] A controller is also installed on the outer side of the housing 1. The first sensor 362, the second sensor 81, the micro vacuum pump 32 and the servo motor 61 are all signal-connected to the controller;

[0060] Specifically, a controller is fixed on the outer side of the housing 1. When the first sensor 362 and the second sensor 81 are subjected to pressure, they will both pass through the controller. The controller realizes the control of the operation of the micro vacuum pump 32 and the servo motor 61. When the micro vacuum pump 32 and the servo motor 61 are operating, they are triggered and then operate for a period of time, and then stop.

[0061] The working principle of the present invention: When the device picks up the lens, at least three steps are required. First, adsorb the lens. Second, carry the adsorbed lens and keep the lens stable. Third, remove the carried lens.

[0062] First, when adsorbing the lens, the air exchange hole 63 of the control rack 62 coincides with the gas exchange hole 43, so that gas can enter the gas exchange pipe 2. Under the action of the self-weight of the negative pressure clamping part 3, it will slide down along the gas exchange pipe 2. When multiple negative pressure clamping parts 3 contact the arc surface of the lens, different negative pressure clamping parts 3 can be located at different positions of the gas exchange pipe 2. Multiple negative pressure clamping parts 3 fit the surface of the lens. The first sensor 362 on the suction cup 36 is squeezed, driving the micro vacuum pump 32 to evacuate the gas in the negative pressure pipe 31, and adsorbing the lens by negative pressure. Then, when the second sensor 81 at the lower end of the limit shaft 8 contacts the platform for placing the lens, the servo motor 61 takes effect, driving the control rack 62 to rotate, so that the air exchange hole 63 is misaligned with the gas exchange hole 43, and the gas inside the gas exchange pipe 2 remains unchanged. Thus, after multiple negative pressure clamping parts 3 adsorb the lens, the position remains unchanged, realizing the handling of lenses with different arcs;

[0063] Second, the carried lens needs to be removed. When removing, first make the second sensor 81 at the lower end of the limit shaft 8 contact the platform for placing the lens, then drive the servo motor 61 to move in the reverse direction, so that the air exchange hole 63 coincides with the gas exchange hole 43, and also make the micro vacuum pump 32 inject gas into the negative pressure pipe 31 to realize the removal of the lens.

[0064] In addition, when the device adsorbs the lens, the device needs to move downward to make the negative pressure clamping part 3 contact the lens, and make the negative pressure clamping part 3 move relatively upward along the gas exchange pipe 2. Since the aperture of the air flow hole 42 is limited, the speed of the outward movement of the gas exchange pipe 2 is limited. Therefore, there is a certain resistance to the upward movement of the negative pressure clamping part 3, enabling the suction cup 36 to fit the lens more quickly and firmly.
