Description

Technical Field

[0001] This invention relates to the field of optoelectronic device manufacturing and packaging technology, and in particular to a nozzle assembly, assembly fixture and mounting equipment. Background Technology

[0002] In the packaging process of semiconductor lasers or other micro-optical systems, the precise mounting of tiny optical lenses, such as mirrors, beam splitters, or collimating lenses, into predetermined positions is one of the key steps determining the optical performance of the laser. The mounting equipment uses a vacuum suction nozzle to pick up the optical lenses from the cartridge, place them in pre-applied adhesive positions, and apply downward pressure to complete the mounting.

[0003] Existing mounting equipment typically employs an integrated nozzle structure, which includes an airflow channel connected to a vacuum generator.

[0004] During the optical lens mounting process, adhesive is pre-applied to predetermined locations. When the suction nozzle adsorbs the optical lens and presses it down onto the adhesive, excess adhesive at the lens edge is squeezed and overflows. Because the suction area is in close contact with the optical lens and maintains a continuous negative pressure, the overflowing adhesive easily enters the internal airflow channels along the suction area under the action of capillary action and negative pressure suction. After the adhesive cures, it can cause partial or complete blockage, affecting the adsorption function.

[0005] The optical lenses to be mounted are typically made of high-hardness glass or quartz. During the repeated alignment, contact, adsorption, and release processes between the suction area and the optical lens, the edges of the suction area will gradually wear down due to continuous friction, resulting in rounded corners or a blunted shape. This reduces the flatness of the adsorption surface, thereby reducing the positioning accuracy of the optical lens.

[0006] If the internal airway becomes blocked or the nozzle structure becomes worn, the entire nozzle needs to be scrapped and replaced with a new one. However, due to limitations in machining tolerances and installation repeatability accuracy, the height, level, and spatial coordinates of the new nozzle relative to the optical lens placement position need to be recalibrated and adjusted. This recalibration and adjustment process is time-consuming, reduces equipment efficiency, and increases labor costs. Summary of the Invention

[0007] One of the objectives of this invention is to provide a suction nozzle assembly to solve the technical problem that the integrated right-angle structure in the prior art is difficult to clean and replace.

[0008] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a suction nozzle assembly for adsorbing an element to be adsorbed, or for removing the element to be adsorbed from the suction nozzle assembly, the suction nozzle assembly comprising: The base has a first air passage inside, which is used to connect to the vacuum generating device. The first adsorption element is connected to the base; A second adsorption element is connected to the first adsorption element, and the first adsorption element and the second adsorption element are connected to form an adsorption head; the adsorption head forms a suction port area, and the suction port area is away from the base; The suction port area includes a suction port, a first adsorption surface and a second adsorption surface. The first adsorption surface is formed on the first adsorption element. The suction port is recessed from the first adsorption surface to the side away from the second adsorption surface.

The third contact surface and the fourth contact surface are in contact.

[0012] As a further improvement of one embodiment of the present invention, the first adsorption member and the protrusion are detachably connected by an adhesive layer, and / or the first adsorption member and the second adsorption member are detachably connected by an adhesive layer.

[0013] As a further improvement of one embodiment of the present invention, the second adsorption member includes a widened portion and a base. The widened portion is disposed at one end of the second adsorption member away from the base, and the base is located between the widened portion and the base. The second adsorption surface is formed on the end face of the widened portion away from the base. The width of the second adsorption surface along the width direction of the adsorption head is greater than the width of the first adsorption surface along the width direction of the adsorption head. The ratio of the width of the second adsorption surface along the width direction of the adsorption head to the width of the base along the width direction of the adsorption head is 1.5:1 to 2:1. The element to be adsorbed has a first dimension along the width direction of the adsorption head and a second dimension along the length direction of the adsorption head. The width of the widened portion is configured to be smaller than the first dimension, and the length of the suction port area along the length direction of the adsorption head is smaller than the second dimension. The suction head is used to enter between adjacent baffles of the optical device, and the suction head has a maximum width, which is smaller than the distance between the adjacent baffles.

[0014] As a further improvement of one embodiment of the present invention, the first adsorption member is provided with a uniform width along the length direction of the adsorption head, and the second adsorption member includes a base, the base being located between the widened portion and the base, the width of the base being equal to the width of the first adsorption member, the width of the widened portion gradually increasing along the direction toward the suction port area, the minimum width of the widened portion being equal to the width of the base, and the maximum width of the widened portion being configured to be the maximum width of the adsorption head; And / or, the material hardness of the second adsorbent is greater than that of fused silica or optical glass.

[0015] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides an assembly fixture for engaging the suction nozzle assembly as described in any of the above technical solutions, thereby assisting in the installation of the first suction member and / or the second suction member onto the base; The assembly fixture includes a first positioning groove and a second positioning groove, which are arranged along the length of the suction nozzle assembly. The shape of the first positioning groove matches at least a portion of the shape of the base, and the shape of the second positioning groove matches at least a portion of the shape of the suction head. The assembly fixture is configured such that, when the base and the suction head are connected, the first positioning groove receives and positions the base, and the second positioning groove receives and positions the suction head.

[0016] As a further improvement of one embodiment of the present invention, the second positioning groove includes a first space and a second space, the first space and the second space are arranged along the thickness direction of the adsorption head, the first space has a limiting inner wall surface, the limiting inner wall surface matches the outer contour of the first adsorption member; the second space has a limiting space, the shape of the limiting space matches the shape of the widened part of the second adsorption member.

[0017] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a mounting device for assembling optical lenses onto optical equipment. The mounting device includes a nozzle assembly and a suction rod according to any one of the above technical solutions. The suction rod has an internal airflow channel that is connected to a vacuum generator. The base is fixed to the suction rod. A first air passage is connected to the airflow channel. After the first adsorption element and / or the second adsorption element are removed from the base and replaced, the spatial position of the suction port area relative to the suction rod remains unchanged. The optical device includes a mounting space for placing multiple elements to be adsorbed. The maximum width of the adsorption head is configured to allow the adsorption head to adsorb the elements to be adsorbed and enter the mounting space together, and to allow the adsorption head to move between adjacent elements to be adsorbed.

[0018] Compared with the prior art, the present invention provides a suction nozzle assembly with a right-angle structure formed by assembly. This overcomes the limitation of one-piece processing in forming right-angle structures, achieving a precise right-angle shape and avoiding the difficulties in cleaning the root and stress concentration problems associated with one-piece right-angle structures in the suction port area. The first and second adsorption surfaces are planes, and the suction port is exposed on the right-angle structure formed by assembly on the plane and is used to generate negative pressure. This facilitates the adhesion between the suction port area and the plane of the element to be adsorbed, forming a right-angle-within-a-right-angle adhesion adsorption, thus enhancing the adsorption effect. The first adsorption element and the base are assembled and connected, and the first adsorption element and the second adsorption element are also assembled and connected, which facilitates the individual replacement of the first adsorption element or the second adsorption element. The adsorption head is assembled and connected to the base as a whole, which facilitates the individual replacement of the adsorption head from the base, reducing costs and reducing equipment setup time. The suction port area is formed by assembling the first adsorption element and the second adsorption element, and can be disassembled, which facilitates the cleaning of overflow colloids that overflow to the suction port and / or the first adsorption surface and / or the second adsorption surface, reducing the residue of overflow colloids. The assembly connection is more prone to separation and breakage under external force, and the force transmission is preferentially interrupted at the assembly connection, thereby protecting the equipment.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0030] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," "third," "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] The terms “connection,” “connected to,” or any other variations are intended to encompass various relative positions where a connection exists, including both direct and indirect connections. A direct connection can be formed through a pneumatic conduit, while an indirect connection can be formed through devices such as valves or sensors, through pneumatic components such as brake control units, or through any other medium such as air.

[0032] Please see Figure 1 This is a schematic diagram of the structure of a suction nozzle assembly 100 provided in an embodiment of the present invention. The suction nozzle assembly 100 is used to adsorb an element 200 to be adsorbed, or to remove the element 200 to be adsorbed from the suction nozzle assembly, so as to move the element 200 to be adsorbed to a predetermined position by adsorption.

[0033] In one specific embodiment, the suction nozzle assembly 100 is used to cooperate with an optical device. The element to be suctioned 200 is an optical lens. The suction nozzle assembly 100 is used to suction the optical lens and move the optical lens to a predetermined position of the optical device. The predetermined position is pre-set with adhesive, solder or other bonding layer. The optical lens is attached to the predetermined position through the bonding layer.

[0034] The nozzle assembly 100 includes: a base 10, a first suction element 30, and a second suction element 50.

[0035] The base 10 has a first air passage 11 inside, which is used to connect to the vacuum generating device.

[0036] The first adsorption element 30 is connected to the base 10.

[0037] The second adsorption element 50 is connected to the first adsorption element 30, and the first adsorption element 30 and the second adsorption element 50 are connected to form an adsorption head 20; the adsorption head 20 forms a suction port area 21, which is away from the base 10.

[0038] The suction area 21 includes a suction port 312, a first adsorption surface 32, and a second adsorption surface 510. The first adsorption surface 32 is formed on the first adsorption member 30. The suction port 312 is recessed from the first adsorption surface 32 towards the side opposite to the second adsorption surface 510. The suction port 312 connects to the first air passage 11 to generate negative pressure. The second adsorption surface 510 is formed on the second adsorption member 50. The first adsorption surface 32 and the second adsorption surface 510 are planar. The first adsorption surface 32 and the second adsorption surface 510 are spliced ​​to form a right-angle structure. The suction port 312 is exposed in the right-angle structure. The right-angle structure is used to adapt to the edge corner of the element to be adsorbed, which is convenient for fitting and adsorbing the edge corner of the element to be adsorbed 200 and for maintaining the nozzle assembly 100. The fact that the suction port 312 is exposed in the right-angle structure means that the suction port 312 can connect to the outside and the first air passage 11.

[0039] The right-angle structure formed by assembling the first adsorption surface 32 and the second adsorption surface 510 can overcome the limitation of the difficulty in forming a right-angle structure in one-piece processing, and obtain a precise right-angle shape. This avoids the problem of one-piece processing producing right-angle structures, which are prone to rounded corner residues or burrs, and the stress concentration that is prone to occur in one-piece angled structures. The first adsorption surface 32 and the second adsorption surface 510 are flat, and the suction port 312 is exposed to the right-angle structure formed by assembling the flat surface and is used to generate negative pressure. This is conducive to the flat contact between the suction port area 21 and the element to be adsorbed 200, forming a right-angle-within-a-right-angle contact adsorption, which enhances the adsorption effect.

[0040] The angles of the right-angle structure are adapted to the angles of the edge corners, meaning that the angles of the right-angle structure and the angles of the edge corners are approximately equal, facilitating a close fit and adhesion. Specifically, combined with... Figure 2 , Figure 5 and Figure 6 As shown, the suction port area 21 is a right-angled space, and the edge corner of the element 200 to be adsorbed is also a right-angled edge corner, resulting in a better adsorption effect between the suction port area 21 and the edge corner. The suction port area 21 can be used for optical lenses with right-angled edge corners, such as cuboid or cube-shaped reflective lenses and beam splitters.

[0041] It should be noted that the right-angle structure is an exact 90°, unlike the integrated right-angle structure which may have issues such as rounded corners and angle deviations due to difficulties in cleaning the root. The first adsorption surface 32 and the second adsorption surface 510 can be precisely assembled through grinding to form a 90° right angle, and the process is simple.

[0042] The first adsorption surface 32 and the second adsorption surface 510 are independent planes, which facilitates flat adhesion. The higher the flatness of the connection between the suction port area 21 and the element to be adsorbed 200, the better the vacuum adsorption. The plane of the first adsorption surface 32 is adapted to the first plane surface of the element to be adsorbed 200, and the plane of the second adsorption surface 510 is adapted to the second plane surface of the element to be adsorbed. The first plane surface and the second plane surface are adjacent and connected to form an edge corner. The first adsorption surface 32 and the second adsorption surface 510 are flatly attached to the first plane surface and the second plane surface of the element to be adsorbed 200, which enhances the adhesion and adsorption effect between the suction port area 21 and the element to be adsorbed 200.

[0043] In one specific embodiment, the element to be adsorbed 200 may include various types of optical lenses such as mirrors, beam splitters, collimating lenses, polarizers, or filters. These optical lenses are manufactured using materials such as fused silica and optical glass. While optical lenses have high hardness, they have low fracture toughness and are prone to cracking and shattering under external force. Mechanical grippers hold the edges of the optical lenses, and the concentrated clamping force easily creates stress concentration at the edges. Furthermore, the mechanical grippers can easily rub against the optical lenses, and the resulting friction particles can contaminate them.

[0044] The first air passage 11 of the base 10 is connected to the vacuum generator, providing a negative pressure channel for the nozzle assembly 100 to achieve adsorption-type mounting. The negative pressure causes the surface of the element to be adsorbed 200 to be uniformly stressed, avoiding the element to be adsorbed 200 from breaking or generating micro-cracks, and ensuring the cleanliness of the element to be adsorbed 200.

[0045] The nozzle assembly 100 is used to attach the element 200 to be attached, such as an optical lens, to an optical device or optical system, such as a laser, optical module, optical sensor, fiber optic coupling system, beam shaping system, optical imaging system, etc. The optical lens needs to be precisely mounted to a predetermined position in the optical device or optical system. This predetermined position is typically treated with adhesive dispensing. The optical lens is fixedly mounted at the predetermined position to form a predetermined optical path, enabling light processing such as reflection, deflection, focusing, collimation, or beam splitting of incident light, thereby achieving the predetermined optical function of the optical device or optical system.

[0046] During the process of adsorbing optical lenses and attaching them to predetermined positions, the suction port area 21 of the nozzle assembly 100 is prone to wear and dulling. In addition, glue or solder is usually placed at the predetermined positions, which can easily be sucked in and cause blockage. The complete scrapping and replacement of the nozzle assembly 100 will cause the optical equipment to be shut down for a long time and readjusted.

[0047] In one specific embodiment, the adsorption head 20 and the base 10 are connected by assembly, which makes it easy to replace the adsorption head 20 separately from the base 10. The base 10 does not need to be disassembled and can remain in the same position. Only the adsorption head 20 needs to be replaced. There is no need to readjust and calibrate the position of the nozzle assembly 100, which reduces the equipment adjustment time and improves the placement efficiency.

[0048] Assembly joints are more prone to separation and breakage under external forces. The force transmission is preferentially interrupted at these joints to protect the equipment. Specifically, when replacing the adsorption head 20 alone, a strong external force, such as a machine impact, is required to separate the adsorption head 20 from the base 10. When the adsorption head 20 and base 10 are not integrally formed but assembled, the assembly joint will preferentially break, protecting other components besides the adsorption head 20, such as the base 10 and the equipment.

[0049] The first adsorption component 30 is replaceable relative to the base 10, and the second adsorption component 50 is replaceable relative to the first adsorption component 30. The first adsorption component 30 and the second adsorption component 50 are also assembled and connected, facilitating the individual replacement of the first adsorption component 30 and / or the second adsorption component 50, thus reducing costs. In practical applications, the specific components requiring replacement may vary depending on the specific problems encountered. For example, if the second adsorption component 50 is severely worn and needs to be replaced separately, it can be directly removed from the base 10 and replaced with a new one.

[0050] In one specific embodiment of this application, when replacing the first adsorption element 30 separately, the adsorption head 20 needs to be completely disassembled, and then the first adsorption element 30 and the second adsorption element 50 need to be disassembled. It is understood that in other embodiments, the first adsorption element 30 can also be disassembled independently from the base 10, simplifying the replacement process of the first adsorption element 30.

[0051] The suction port area 21 is assembled from the first adsorption element 30 and the second adsorption element 50, and can be disassembled to facilitate cleaning of the overflow colloid that overflows to the suction port 312 and / or the first adsorption surface 32 and / or the second adsorption surface 510, thereby reducing the residue of the overflow colloid.

[0052] Understandably, if a certain amount of adhesive is pre-installed at a predetermined location, when the element to be adsorbed 200 is pressed down to bond with the adhesive, the adhesive will overflow along the edge of the element to be adsorbed 200 under the pressing action. Both the first adsorption surface 32 and the second adsorption surface 510 are in contact with and adsorb the element to be adsorbed 200. Under the action of capillary action and negative pressure adsorption, the overflowing adhesive can easily diffuse to the first adsorption surface 32 and / or the second adsorption surface 510 in a very small gap, and finally enter the suction port 312. The outer space of the suction port 312 can be used to accommodate the adhesive.

[0053] The suction port 312 can accommodate a small amount of overflowing glue without affecting the adsorption function. In actual field, it is necessary to clean the overflowing glue in the suction port area 21 in time to prevent excessive accumulation from clogging the suction port 312, reducing the flatness of the first adsorption surface 32 and the second adsorption surface 510, and thus affecting the stable adsorption of the optical lens 200. Therefore, when the first adsorption surface 32 and the second adsorption surface 510 are spliced ​​together, it is easy to clean the overflowing glue.

[0054] In one specific embodiment, the first adsorption member 30 includes a groove 31 that extends along the length of the first adsorption member. The groove 31 includes a long groove 311. When the base 10 and the adsorption head 20 are connected, the long groove 311 is closed to form a second air passage. The suction port 312 constitutes part of the groove 31 and is connected to the outside. The second air passage connects the suction port 312 and the first air passage 11 to form a complete negative pressure channel.

[0055] Combination Figure 3 , Figure 4 As shown, the first adsorption element 30 is elongated, and the groove 31 is also elongated. The groove 31 is formed on the side surface facing the second adsorption element 50. The groove 31 includes an elongated groove 311 and a suction port 312. One end of the elongated groove 311 is aligned with the first air passage 11, and the suction port 312 is located at the end of the elongated groove 311 away from the first air passage 11. When the elongated groove 311 is covered, a sealed second air passage can be formed, which provides negative pressure to the suction port 312.

[0056] The first adsorption element 30 protrudes a distance beyond the second adsorption element 50 along the length of the adsorption head, thereby forming the suction port area 21, and the suction port 312 is exposed outward.

[0057] The width of the suction port 312 along the width direction of the first adsorption element is greater than the width of the long groove 311 along the width direction of the first adsorption element; the length of the suction port 312 along the length direction of the first adsorption element is less than the length of the long groove 311 along the length direction of the first adsorption element; it can be seen that the long groove 311 mainly extends along the length direction of the first adsorption element, and the suction port 312 mainly extends along the width direction of the first adsorption element.

[0058] Understandably, the wider sides of the suction port 312 than the long groove 311 can accommodate overflowing glue without affecting the generation of negative pressure. The suction port 312 is relatively short but slightly wider. The size of the suction port 312 cannot be too small, otherwise it will affect the adsorption capacity of the optical lens; the size of the suction port 312 cannot be too large either, otherwise the flatness requirement of the optical lens 200 will be too high. If the flatness of the element to be adsorbed 200 does not meet the standard, it is easy to leak air and cause loss of vacuum.

[0059] In one specific embodiment, the suction port 312 is a circular or elliptical groove. In the field process, machining and cutting are usually done in the form of cylindrical grooves. Therefore, the suction port 312 is easy to process into a circular or elliptical shape, and can increase the cross-sectional area of ​​the negative pressure output by the suction port 312. In other words, it increases the negative pressure action area of ​​the adsorption element 200.

[0060] It is understandable that the second air passage formed by the long groove 311 is relatively straight, narrow and long in order to adapt to the actual application scenario, in which the suction nozzle assembly 100 needs to be inserted into the specific optical equipment and the material box storing the optical lens to pick up and transfer the element 200 to be adsorbed.

[0061] Combination Figure 9 , Figure 10 As shown, the mounting space inside the laser 1000 and the storage space of the material box are limited. The adsorption head 20 needs to be made thin and long to enter the laser 1000 and the material box. Furthermore, if the adsorption head 20 is too large, it will also occupy observation space. When the adsorption head 20 places the element 200 to be adsorbed into the predetermined position, space also needs to be reserved for observing the state of the element 200. The long groove 311 has a slender structure, and a certain thickness of sidewall needs to be reserved on the outer periphery of the long groove 311 to ensure the structural stability of the first adsorption element 30.

[0062] In one specific embodiment, taking the smallest size element to be adsorbed 200 that the suction nozzle assembly 100 needs to adsorb as an example, the element to be adsorbed is stored in the receiving groove of the material box. The width of the receiving groove is adapted to the width of the element to be adsorbed 200. The width of the first adsorption member 30 is slightly smaller than the width of the receiving groove, so that the part of the suction port area 21 formed by the first adsorption member 30 can extend into the receiving groove until the second adsorption surface abuts against the second surface of the optical lens. The second adsorption surface can play a limiting role in the adsorption process.

[0063] Understandably, the width of the first adsorption member 30 is configured to be slightly smaller than the width of the receiving groove of the smallest size adsorption element 200. This allows the first adsorption member 30 to accommodate receiving grooves of larger sizes of adsorption elements 200, enabling the partial suction area 21 formed by the first adsorption member 30 to adsorb elements 200 of more specifications. The preset interval between two adjacent adsorption elements 200 is greater than the thickness of the first adsorption member 30.

[0064] The base 10 includes a protrusion 12; the protrusion 12 has a first contact surface 121 facing the first adsorption member 30, and the second adsorption member 50 has a second contact surface 52 facing the first adsorption member 30. The first contact surface 121 is aligned with the second contact surface 52 along the length direction of the adsorption head. The first contact surface 121 and the second contact surface 52 are respectively in contact with the first adsorption member 30 to jointly seal the long groove 311. The suction port 312 is exposed at the end of the long groove 311 away from the base 10.

[0065] Combination Figure 3 , Figure 4 As shown, the base 10 includes a main body 14, which is used to fix the suction rod of the mounting device. In order to facilitate the connection between the suction head 20 and the base 10, the base 10 is provided with a protrusion 12, which is parallel to the suction head 20. The first air passage 11 passes through the connecting end face 141, and the protrusion 12 extends from the first air passage 11.

[0066] It is understandable that without the protrusion 12, the adsorption head 20 can only be connected to the connecting end face 141 of the base 10 through the end face with a small cross-sectional area. The connection area is too small, which can easily lead to an unstable connection between the adsorption head 20 and the base 10, resulting in air leakage.

[0067] The protrusion 12 extends from the connecting end face 141 and covers the first adsorption member 30 for a distance along the length direction of the adsorption head 20, thereby increasing the contact area between the protrusion 12 and the first adsorption member 30, which is beneficial to the stable connection between the adsorption head 20 and the base 10.

[0068] The protrusion 12 has a third contact surface 122 facing the second adsorption member 50. The second adsorption member 50 has a fourth contact surface 53 facing the protrusion 12. The third contact surface 122 and the fourth contact surface 53 are parallel and in contact with each other, and are used to jointly close the long groove 311.

[0069] Combination Figure 1 , Figure 4 As shown, along the length of the first adsorption member 30, the protrusion 12 and the second adsorption member 50 are also closely connected to each other to jointly cover the long groove 311. The sum of the lengths of the protrusion 12 and the second adsorption member 50 is equivalent to the length of the long groove 311.

[0070] In a specific application scenario, the suction nozzle assembly 100 is used to adsorb optical lenses 200 in a vertical direction. The length direction of the suction head 20 is parallel to the vertical direction. The first contact surface 121 and the second contact surface 52 are vertical planes. The side surface of the groove 31 of the first suction member 30 is also a vertical plane. The third contact surface 122 and the fourth contact surface 53 are horizontal planes.

[0071] Combination Figure 4 As shown, the first contact surface 121 of the protrusion 12 is provided with a recessed groove 124. The recessed groove 124 and the long groove 311 together form part of the second air passage. The second contact surface 52 of the second adsorption member 50 is a complete plane without a recessed groove. The depth and width of the long groove 311 are consistent, so that the cross-sectional area of ​​the second air passage in the corresponding section of the protrusion 12 is smaller than the cross-sectional area of ​​the second air passage in the corresponding section of the second adsorption member 50, thereby enhancing the suction force near the suction port 312.

[0072] The first adsorption member 30 and the protrusion 12 are connected by an adhesive layer, and / or the first adsorption member 30 and the second adsorption member 50 are connected by an adhesive layer. In this application, the assembly connection of the first adsorption member 30 and the base 10 via an adhesive layer means that the first adsorption member 30 and the protrusion 12 are detachably connected. The assembly connection of the second adsorption member 50 and the first adsorption member 30 via an adhesive layer means that the second adsorption member 50 can be detached separately from the first adsorption member 30, or it can be detached from the base 10 together with the first adsorption member 30.

[0073] It should be noted that the adhesive layer connection method in this application is interpreted as a detachable connection, meaning the adhesive layer can be released from its bonded state under external force. The first adsorption member 30 can be first connected to the second adsorption member 50, and then the first adsorption member 30 can be connected to the protrusion 12 of the base 10; alternatively, the first adsorption member 30 can be first connected to the protrusion 12 of the base 10, and then the second adsorption member 50 can be connected to the first adsorption member 30. The second adsorption member 50 is connected to the base 10 through the first adsorption member 30; in other words, there is no detachable connection structure between the second adsorption member 50 itself and the base 10.

[0074] When the adsorption head 20 needs to be replaced, the first adsorption component 30 and the protrusion 12 can be debonded under external force, or the adhesive layer between the first adsorption component 30 and the protrusion 12 can be melted by heating or light, thereby removing the adsorption head 20. The new adsorption head 20 is then bonded to the protrusion 12 with adhesive. After the adhesive cures, the adsorption head 20 and the base 10 are assembled.

[0075] This application allows for the separate replacement of the second adsorption element 50. Similarly, the second adsorption element 50 can be separated from the first adsorption element 30 by external force, heating, or light exposure, which is equivalent to separating it from the base 10. The replaced second adsorption element 50 is bonded to the first adsorption element 30 with adhesive. After the adhesive cures, the second adsorption element 50, the first adsorption element 30, and the protrusion 12 are assembled.

[0076] The second adsorption element 50 is made of a material with a hardness greater than that of fused silica or optical glass, making it less prone to wear and passivation. When the adsorption element 200 is an optical lens, the mainstream material for optical lenses is fused silica or optical glass. The material of the second adsorption element 50 is harder than that of the optical lens, and can specifically be made of zirconia ceramic. During repeated adsorption processes with multiple optical lenses, it is less likely to be worn by the optical lenses, reducing replacement costs.

[0077] The second adsorption member 50 includes a widened portion 51 and a base 54. The widened portion 51 is located at one end of the second adsorption member 50 away from the base 10, and the base 54 is located between the widened portion 51 and the base 10. The second adsorption surface 510 is formed on the end face of the widened portion 51 away from the base 10. The width of the second adsorption surface 510 along the width direction of the adsorption head is greater than the width of the first adsorption surface 32 along the width direction of the adsorption head. The ratio of the width of the second adsorption surface 510 along the width direction of the adsorption head to the width of the base along the width direction of the adsorption head is 1.5:1 to 2:1. In other words, the width ratio of the second adsorption surface 510 to the first adsorption surface 32 is 1.5:1 to 2:1, which increases the contact area with the element to be adsorbed 200, which is beneficial to the stability and balance of the adsorption action.

[0078] The element to be adsorbed 200 has a first dimension along the width direction of the adsorption head and a second dimension along the length direction of the adsorption head. The width of the second adsorption surface 510 is configured to be smaller than the first dimension, and the length of the suction port area 21 along the length direction of the adsorption head is smaller than the second dimension. The element to be adsorbed 200 is wider than the second adsorption surface 510, and its bottom needs to protrude from the suction port area 21. In actual scenarios, it is used for dispensing. The element to be adsorbed 200 has various specifications. The adsorption head 20 is made according to the smallest specification, while being compatible with other larger specifications.

[0079] The adsorption head 20 is used to enter between adjacent baffles of the optical device. The adsorption head 20 has a maximum width that is smaller than the distance between adjacent baffles to allow the adsorption head 20 to enter.

[0080] The first adsorption element 30 is provided with a uniform width along the length direction of the adsorption head. The width of the base 54 is equal to the width of the first adsorption element 30. Along the direction toward the suction port area 21, the width of the widening part 51 gradually increases. The minimum width of the widening part 51 is equal to the width of the base 54. The maximum width of the widening part 51 is configured to be the maximum width of the adsorption head 20, which is beneficial for the adsorption head 20 to adsorb the element 200 to be adsorbed into a limited predetermined position.

[0081] The nozzle assembly 100 is used to attach the element 200 to be adsorbed to a predetermined position in the optical device. The internal space of the optical device and the accommodating space of the material box are limited, and it is impossible to accommodate a large-sized adsorption head 20. By appropriately widening one end of the second adsorption member 50, it can not only improve the stability and balance of the adsorption action, but also take into account the space limitations inside the optical device.

[0082] Specifically, combined Figure 4 , Figure 5 As shown, the first adsorption member 30 has a consistent width along the length of the adsorption head, and the protrusion 12 also has a consistent width along the length of the adsorption head. The second adsorption member 50 is flat, and its main body width is the same as the width of the protrusion 12 and the width of the first adsorption member 30. The width of the widened portion 51 is greater than the base width of the second adsorption member 50, and the width of the widened portion 51 along the width direction of the adsorption head is greater than the width of the first adsorption member 30 along the width direction of the adsorption head, and also greater than the width of the protrusion 12. The width of the widened portion 51 gradually increases, reaching its maximum at the second adsorption surface 510.

[0083] Specifically, the maximum width below the widened portion 51 is 5.6 mm, and the width of the base 54 is 3.6 mm. The ratio of the maximum width of the widened portion 51 to the width of the base 54 should be 1.56:1. Therefore, the width of the second adsorption surface 510 is 5.6 mm, the width of the first adsorption surface 32 is 3.6 mm, and the ratio of the width of the second adsorption surface 510 to the width of the first adsorption surface 32 is 1.56:1.

[0084] It should be noted that the suction nozzle assembly 100 of this application preferably does not include other clamping structures. The element to be adsorbed 200 is fixed by the adsorption of the suction port area 21. Except for the limitation of the first adsorption surface 32 and the second adsorption surface 510, the element to be adsorbed 200 is not subject to other limitations or positioning. The suction port area 21 can accommodate more types and larger sizes of elements to be adsorbed 200.

[0085] Combination Figure 7 , Figure 8 As shown, this application also protects an assembly fixture 400, which is used to cooperate with the nozzle assembly 100 in any of the above technical solutions to assist the first suction member 30 and / or the second suction member 50 in being installed on the base 10, or to assist the nozzle assembly 100 in being aligned and installed with the mounting equipment.

[0086] In one application scenario, the base 10 is fixed to the suction rod of the mounting equipment. After the first suction component 30 and / or the second suction component 50 are removed from the base 10 and replaced, the spatial position of the suction port area 21 relative to the suction rod remains unchanged. When the first suction component 30 and / or the second suction component 50 need to be replaced on-site, the assembly fixture 400 precisely limits and guides the first suction component 30 and / or the second suction component 50, ensuring the consistency of coaxiality, end face height, and planar fit between the first suction component 30 and / or the second suction component 50 and the base 10. This eliminates manual alignment errors and ensures that the replacement of the first suction component 30 and / or the second suction component 50 in mass production does not require complex machine adjustment work, improving the convenience of maintenance and replacement and production efficiency.

[0087] In another application scenario, the nozzle assembly 100 needs to be installed as a whole onto the placement equipment, and the assembly fixture 400 is used to assist in the precise alignment of the nozzle assembly 100 and the placement equipment.

[0088] The assembly fixture 400 includes a first positioning groove 410 and a second positioning groove 420, which are arranged along the length of the nozzle assembly 100. The shape of the first positioning groove 410 at least matches the shape of a portion of the base 10, and the shape of the second positioning groove 420 at least matches the shape of a portion of the suction head 20. The assembly fixture 400 is configured such that, when the base 10 and the suction head 20 are connected, the first positioning groove 410 receives and positions the base 10, and the second positioning groove 420 receives and positions the suction head 20.

[0089] The shape of the first positioning groove 410 matches the shape of a portion of the base 10 to limit or position the base 10 within the first positioning groove 410, and the shape of the second positioning groove 420 matches the shape of a portion of the suction head 20 to limit or position the suction head 20 within the second positioning groove 420.

[0090] In one application scenario, the base 10 is fixed to the suction rod of the mounting equipment. The suction head 20 needs to be reassembled with the base 10. The suction head 20 is positioned in the second positioning groove 420. Then, the assembly fixture 400 and the suction head 20 cooperate with the base 10. The base 10 enters the first positioning groove 410. The suction head 20 and the protrusion 12 are aligned and bonded, completing the precise alignment and connection between the suction head 20 and the base 10.

[0091] In another application scenario, the nozzle assembly 100 is positioned in the assembly fixture 400 and aligned with the suction rod of the mounting equipment. After precise alignment, the base 10 is fixedly connected to the suction rod.

[0092] The second positioning groove 420 includes a first space 421 and a second space 422. The first space 421 and the second space 422 are arranged along the thickness direction of the adsorption head. The first space 421 has a limiting inner wall surface that matches the outer contour of the first adsorption member 30. The second space 422 has a limiting space whose shape matches the shape of the widened portion 51 of the second adsorption member 50, so as to position or limit the first adsorption member 30 and the second adsorption member 50 respectively.

[0093] The assembly fixture 400 is configured such that, in the connected state, the first adsorption member 30 and the protrusion 12 of the base 10 are received and positioned in the first space 421, and the second adsorption member 50 is received and positioned in the second space 422.

[0094] Specifically, the first space 421 is rectangular, and its length and width are adapted to the length and width of the first adsorption member 30 to confine the first adsorption member 30 within it. The second space 422 is connected to the first space 421, and the width of the second space 422 is equal to the width of the first space 421. One end of the second space 422 is provided with a trapezoidal limiting space, which exactly matches the widened part 51 to confine the second adsorption member 50 entirely within it.

[0095] In one application scenario, the second adsorption component 50 needs to be replaced separately. The assembly fixture 400 is first aligned and engaged with the base 10 and the first adsorption component 30. Then, the second adsorption component 50 is installed into the second space 422 to complete the precise alignment of the second adsorption component 50, the first adsorption component 30, and the protrusion 12.

[0096] The length and width of the second positioning groove 420 are perfectly matched to the first adsorption member 30. However, the second positioning groove 420 is deep enough to accommodate both the first adsorption member 30 and the second adsorption member 50 at the same time. This results in the lower space and the upper space of the second positioning groove 420 forming a first space 421 and a second space 422. The second space 422 includes a positioning space for the widened part 51, thereby achieving an independent positioning function for the second adsorption member 50.

[0097] This application also protects a mounting device for assembling a component 200 to be adsorbed onto an optical device. The mounting device includes a nozzle assembly 100 and a suction rod according to any of the above technical solutions. The suction rod has an airflow channel connected to a vacuum generator. A base 10 is fixed to the suction rod, and a first air passage 11 is connected to the airflow channel. In actual field, the base 10 is fixed relative to the suction rod, so that after the first adsorption component 30 and / or the second adsorption component 50 are replaced, the spatial position of the suction port area 21 relative to the suction rod remains unchanged, and there is no need to readjust the nozzle assembly 100.

[0098] The optical device includes a mounting space for placing multiple elements 200 to be adsorbed. The maximum width of the adsorption head 20 is configured to allow the adsorption head 20 to adsorb the elements 200 to be adsorbed together to enter the mounting space and to allow the adsorption head to move between adjacent elements 200 to be adsorbed. The maximum width of the adsorption head 20 means the maximum width of the widening portion 51. The size design of the widening portion 51 takes into account the limited internal space of the optical device and the limited capacity of the material box.

[0099] Combination Figure 9 , Figure 10 As shown, the optical device is a laser 1000. The mounting equipment is used to assemble the laser 1000. More specifically, it is used to adsorb the optical lenses stored in the material box one by one to the predetermined positions of the laser 1000 and perform downward mounting. The predetermined positions of the laser 1000, such as the bottom wall of the laser 1000, have pre-applied adhesive. The size of the adsorption head 20 needs to consider not only the strength of the suction force but also the limitations of the mounting space of the laser 1000 and the capacity of the material box, so that the adsorption head 20 can enter the material box to pick up the optical lenses and move together with the adsorbed optical lenses into the limited mounting space within the laser 1000.

[0100] The beneficial effects of this invention are as follows: the right-angle structure is assembled, which overcomes the limitation of one-piece processing making it difficult to form a right-angle structure, and obtains a precise right-angle shape, avoiding the problems of difficult root cleaning and stress concentration in the one-piece angled structure of the suction port area; the first adsorption surface 32 and the second adsorption surface 510 are planes, and the suction port is exposed on the plane to form a right-angle structure and is used to generate negative pressure, which is conducive to the plane contact between the suction port area 21 and the adsorption element 200, forming a right-angle-within-a-right-angle contact adsorption, enhancing the adsorption effect; the first adsorption element 30 and the base 10 are assembled and connected, and the first adsorption element 30 and the second adsorption element 50 are assembled together. The connection facilitates the individual replacement of the first adsorption element 30 or the second adsorption element 50, reducing costs and equipment setup time. The adsorption head 20 is assembled and connected to the base 10 as a whole, facilitating the individual replacement of the adsorption head 20 from the base 10, reducing costs and equipment setup time. The suction port area 21 is formed by assembling the first adsorption element 30 and the second adsorption element 50 and can be disassembled, facilitating the cleaning of overflow colloids that overflow to the suction port 312 and / or the first adsorption surface 32 and / or the second adsorption surface 510, reducing the residue of overflow colloids. The assembly connection is more prone to separation and breakage under external force, and the force transmission is preferentially interrupted at the assembly connection, thereby protecting the equipment.

[0101] This can be formed by referring to any of the technical solutions provided above, and will not be elaborated here.

[0102] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0103] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
