Description

TECHNICAL FIELD

[0001] The application relates to the technical field of lenses, in particular to a lens array assembly structure. BACKGROUND

[0002] A lens is an optical element made of transparent material (such as glass, crystal, etc.), the surface of which is a part of a spherical surface, or is composed of a spherical surface and a plane. A lens array is an array composed of a series of micro-lenses, the shape, focal length, arrangement structure and duty cycle of which can be adjusted to achieve specific optical functions.

[0003] The dispensing process in the lens array assembly is a key step, which involves the fixation and sealing between lens units, and is crucial to the overall performance and stability of the lens array.

[0004] For example, the patent with the publication number CN208873763U discloses an ultraviolet LED quartz lens assembly structure. The patent uses a jig array arrangement and a die bonder to complete the assembly operation, and the suction nozzle on the die bonder is made of hard plastic with a conical hole opening, thereby increasing the contact surface with the lens and having sufficient adsorption capacity.

[0005] However, in actual implementation, the glue is dropped onto the substrate support, and in the initial stage of dispensing, the glue may accumulate on the substrate support due to gravity, resulting in uneven distribution of the glue. If the glue is not evenly distributed or the coating thickness is inconsistent, it may cause the adhesion between the lens array and the assembly structure to decrease, which may cause loosening or falling off when used for a long time or subjected to external forces.

[0006] Therefore, it is necessary to provide a lens array assembly structure to solve the above problems.

[0007] It should be noted that the above information disclosed in this background section is only used to understand the background technology of the concept of the application, and therefore, it can contain information that does not constitute prior art. SUMMARY

DETAILED DESCRIPTION

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0037] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0038] As Figures 1-2As shown, the present application provides a lens array assembly structure, which comprises a bracket 1 and a mounting plate 4 fixedly arranged at the upper end of the bracket 1, and the mounting plate 4 is used for mounting various components;

[0039] Meanwhile, a clamping mechanism 2 is fixedly arranged on the mounting plate 4, and the clamping mechanism 2 is used for clamping and fixing other parts, so that the dispensing operation can be smoothly carried out;

[0040] The clamping mechanism 2 comprises a connecting block 211 fixedly arranged at the lower end of the mounting plate 4, a gas cylinder 210 fixedly arranged on the connecting block 211, a support block 212 vertically arranged at the output end of the gas cylinder 210, a guide groove 5 formed in the mounting plate 4, and a double-shaft gas cylinder 213 vertically penetrating through the guide groove 5 and fixedly connected to the support block 212;

[0041] The output ends of the double-shaft gas cylinder 213 on both sides are fixedly provided with fixed blocks 214, and the fixed blocks 214 are used for directly contacting with the fixed components, so that the double-shaft gas cylinder 213 can drive the two fixed blocks 214 to move away from or close to each other, thereby achieving the purpose of clamping;

[0042] When it is necessary to fix, the gas cylinder 210 pushes the support block 212 to move along the guide groove 5 until the two fixed blocks 214 touch the components to be fixed and stop, at which time the double-shaft gas cylinder 213 drives the two fixed blocks 214 to move close to each other, so that the fixed blocks 214 clamp the components, and vice versa;

[0043] Meanwhile, the two groups of fixed blocks 214 clampingly fix a base plate 215, and the base plate 215 is used for placing lenses, and a plurality of mounting cavities (not marked in the figure) are formed in the base plate 215, and the mounting cavities are used for mounting and positioning lenses, and mounting rings 216 are fixedly arranged in the mounting cavities, and the mounting rings 216 form a step in the mounting cavities, and the step is used for directly contacting with the lenses;

[0044] When the clamping mechanism 2 is used to fix the base plate 215, the lenses can be placed into the mounting cavities on the base plate 215, so that the mounting is completed;

[0045] As shown in Figure 1 and Figures 3-4 In order to stably install the lenses on the base plate 215, it is necessary to perform dispensing operation on each mounting cavity on the base plate 215, so that the lenses can be stably adhered to the base plate 215, and a displacement mechanism 3 is fixedly arranged at the upper end of the mounting plate 4, and the displacement mechanism 3 is used for moving the dispensing equipment, so that the dispensing operation can be performed on each mounting cavity;

[0046] The displacement mechanism 3 adopts a three-axis screw transmission mechanism commonly used in the prior art and suitable for the present embodiment, and a motor 30 is fixedly installed at the output end of the displacement mechanism 3, so that the motor 30 can be arbitrarily moved in the X / Y / Z three directions under the driving of the displacement mechanism 3;

[0047] In order to prevent the glue from flowing downward due to gravity and causing uneven distribution of the glue on the substrate 215 in the initial stage of dispensing, and to avoid poor use effect after lens installation, a dispensing assembly 31 is fixedly arranged at the output end of the motor 30, and the dispensing assembly 31 is used for dispensing operation on the inner wall of the installation cavity;

[0048] The dispensing assembly 31 includes a fixed seat 310 fixedly arranged at the output end of the motor 30, an adjusting piece 311 fixedly arranged on the fixed seat 310, a sliding groove 312 formed on the adjusting piece 311, and a sliding block 314 slidably arranged on the sliding groove 312. A fixing screw (not shown in the figure) is threadedly arranged on the sliding block 314, and is used for locking or unlocking the sliding block 314. When the fixing screw is rotated to be close to the sliding block 314, the sliding block 314 is locked, so as to prevent displacement during dispensing. When the fixing screw is rotated to be away from the sliding block 314, the sliding block 314 is unlocked, so that the operator can move the sliding block 314 to slide along the sliding groove 312 on the adjusting piece 311;

[0049] Meanwhile, the glue valve 313 is arranged on the sliding block 314, and is used for uniformly extruding the glue. The glue valve 313 is driven to rotate by the motor 30, so as to coat the glue on the inner wall of the installation cavity. A glue head 315 is fixedly arranged at the output end of the glue valve 313, and the output end of the glue head 315 is obliquely cut. The oblique surface of the glue head 315 is matched with the inner wall of the installation cavity, so as to further uniformly coat the glue on the inner wall of the installation cavity;

[0050] It should be noted that the output end of the glue head 315 is provided with an oblique surface, and the oblique surface is matched with the inner wall of the installation cavity on the substrate 215. The oblique surface can more closely contact the surface of the assembly structure, reduce the loss and accumulation of the glue during the flow process, and at the same time, the inner wall of the installation cavity can provide a stable support surface, so that the glue is not easy to deviate or deform during the coating process due to the influence of gravity;

[0051] In addition, the glue can be uniformly coated on the inner wall of the installation cavity in a relatively consistent manner by rotating the dispensing assembly, so as to avoid excessive accumulation of the glue in a certain area of the installation cavity or lack of the glue in another area, and to alleviate the uneven phenomenon of the glue to different degrees;

[0052] And the position and angle of the glue valve 313 can be adjusted by sliding the slider 314 along the sliding groove 312 on the adjusting sheet 311, so as to adapt to various installation cavities;

[0053] Before the glue dispensing starts, the staff can adjust the position of the glue valve 313 on the adjusting sheet 311 according to different sizes of the installation cavities, until the bevel surface of the glue head 315 can be fitted with the inner wall of the installation cavity, so that the glue can be further uniformly coated on the inner wall;

[0054] When the glue dispensing starts, the motor 30 drives the glue valve 313 to rotate along the inner wall of the installation cavity, so that the glue can be uniformly coated on the inner wall of the installation cavity, that is, the glue dispensing operation is completed.

[0055] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
