Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to a glass bonding auxiliary device. Background Technology

[0002] Optical lenses are widely used in many optical devices such as cameras, telescopes, microscopes, and eyeglasses. Their performance directly affects the imaging quality of the devices. In order to meet the needs of different optical systems, it is often necessary to bond multiple lenses with specific optical parameters together to construct composite optical elements.

[0003] Current technologies are inadequate for large-scale production. Traditional processes typically involve applying adhesive individually to each lens on a workbench before placing it in the designated position for bonding. This process is not only cumbersome but also prone to lens misalignment due to repeated operations. Manual bonding of each lens, from adhesive application and alignment to initial fixation, takes at least several minutes. Furthermore, worker fatigue after prolonged work further reduces efficiency. Even with less automated bonding equipment, the hourly lens processing capacity is limited due to cumbersome procedures and slow response times. In today's booming optical product market, such production efficiency severely restricts capacity. Additionally, ordinary dispensing equipment struggles to precisely control the amount and uniformity of adhesive extrusion. Excessive adhesive overflows and contaminates other parts of the lens, affecting optical performance; insufficient adhesive results in weak bonding. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a glass bonding auxiliary device, comprising a base, a first baffle symmetrically connected to the base, and a second baffle mounted on the base. A glass body is disposed on the base, and an extrusion assembly is provided on the base. The extrusion assembly includes a support mechanism and a limiting mechanism.

[0005] The support mechanism includes a glue storage plate, a glue dispensing rod, and a drive cylinder. The glue storage plate is mounted on a first baffle plate, and multiple support plates are connected to the glue storage plate. The glue dispensing rod is mounted on the support plate. A push plate is also provided inside the glue storage plate, and a push rod is mounted on the push plate. The drive cylinder is mounted on the first baffle plate and its output end is connected to the push plate.

[0006] In a further technical solution, the multiple support plates are distributed in two groups, and both groups of support plates are composed of conical plates and rectangular plates, with the rectangular plates of the support plates being attached to the glass body.

[0007] In a further technical solution, the dispensing rod is composed of a slanted rod, a straight rod, and a tapered rod. The tapered rod is fixedly connected to the glue storage plate. The straight rod is located at the end face of the tapered rod away from the glue storage plate, and the slanted rod is located at the end face of the straight rod away from the tapered rod.

[0008] In a further technical solution, a piston push block is installed at the free end of the push rod away from the push plate, and the piston push block can be in contact with the straight rod.

[0009] In a further technical solution, the limiting mechanism includes a placement groove, a stop block, and a spring. The placement groove is symmetrically opened on the dispensing rod, the stop block is symmetrically arranged inside the dispensing rod, and the spring is compressed and arranged between the placement groove and the spring.

[0010] In a further technical solution, a large oblique surface corresponding to the piston pusher is provided on the surface of the stop block near the glue storage plate. The stop block is pushed by the piston pusher through the large oblique surface. A small oblique surface is provided on the surface of the stop block away from the glue storage plate.

[0011] In a further technical solution, the limiting mechanism also includes a blocking plate and a blocking pad. The blocking plate is hinged to the free end of the dispensing rod, and the blocking pad is installed on the blocking plate and fits against the dispensing rod.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a push plate and a drive cylinder to work together, the drive cylinder pushes the push plate, which in turn drives the piston push block to squeeze the glue in the glue storage plate into the glue dispensing rod. The special structure of the glue dispensing rod guides the glue between the glass bodies, achieving the effect of uniformly and stably squeezing the glue into the glass bonding area. At the same time, the piston push block pushes the large beveled surface of the stop block, causing the stop block to overcome the spring force and retract into the placement groove to make room. When the piston push block retracts, the spring resets the stop block, thus controlling the forward path of the piston push block during the glue extrusion process. Attached Figure Description

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figures 1-5 As shown, a glass bonding auxiliary device includes a base 1, a first baffle 2 symmetrically connected to the base 1, and a second baffle 3 installed on the base 1. A glass body is provided on the base 1, and an extrusion assembly 4 is provided on the base 1. The extrusion assembly 4 includes a support mechanism 40 and a limiting mechanism 41.

[0024] The support mechanism 40 includes a glue storage plate 401, a glue dispensing rod 403, and a drive cylinder 406. The glue storage plate 401 is mounted on the first baffle 2, and multiple support plates 402 are connected to the glue storage plate 401. The glue dispensing rod 403 is mounted on the support plates 402. The multiple support plates 402 are distributed in two groups, and both groups of support plates 402 are composed of conical plates and rectangular plates. The rectangular plates of the support plates 402 are in contact with the glass body. The glue dispensing rod 403 is composed of a diagonal rod, a straight rod, and a conical rod. The tapered rod and the glue storage plate 401 are fixedly connected. The straight rod is located at the end face of the tapered rod away from the glue storage plate 401, and the inclined rod is located at the end face of the straight rod away from the tapered rod. A push plate 404 is also provided inside the glue storage plate 401. A push rod 405 is installed on the push plate 404. A piston push block is installed at the free end of the push rod 405 away from the push plate 404. The piston push block can fit in contact with the straight rod. The drive cylinder 406 is installed on the first baffle 2 and its output end is connected to the push plate 404.

[0025] The working principle of the above technical solution is as follows:

[0026] The glass body is placed on the base 1, and the first baffle 2 and the second baffle 3 initially limit and fix the glass body, placing it in a suitable bonding position. At this time, the glue storage plate 401 stores glue for glass bonding;

[0027] By activating the drive cylinder 406, the output end of the drive cylinder 406 pushes the push plate 404 to move within the glue storage plate 401. The push plate 404 drives the connected push rod 405 and piston push block to move together. Since the piston push block is in contact with the straight rod of the glue dispensing rod 403, when the push plate 404 is pushed, the piston push block will squeeze the glue in the glue storage plate 401 into the glue dispensing rod 403. The glue first enters the conical rod fixedly connected to the glue storage plate 401. The structure of the conical rod can play a certain role in converging and guiding the glue, making the glue flow more smoothly to the straight rod. At the same time, the conical rod prevents the piston push block from directly inserting into the straight rod, which would result in insufficient glue introduction. Then the glue flows through the straight rod... When the rod reaches the inclined rod position, due to the certain inclination of the inclined rod, under the combined action of gravity and extrusion force, the glue will gradually flow out along the inclined rod and into the gap between the glass bodies, completing the glue extrusion process. The support plate 402 is composed of a conical plate and a rectangular plate, and the rectangular plate is attached to the glass body. During the glue extrusion process, the support plate 402 can support the gap between the glass bodies, ensuring the relative position stability of the glass bodies, which is conducive to the glue being evenly filled between the glass bodies and improving the bonding effect. At the same time, it can prevent the two bonded glass bodies from colliding and breaking when the support plate 402 moves out from between the glass bodies.

[0028] By setting the push plate 404 and the drive cylinder 406 to cooperate with each other, the drive cylinder 406 pushes the push plate 404, which in turn drives the piston push block to squeeze the glue in the glue storage plate 401 into the glue dispensing rod 403. The glue dispensing rod 403 uses a special structure of inclined rod, straight rod and conical rod to guide the glue between the glass bodies, thus achieving the effect of uniformly and stably squeezing the glue into the glass bonding part.

[0029] In another embodiment, such as Figure 4 and Figure 5 As shown, the limiting mechanism 41 includes a placement groove, a stop block 410, and a spring 411. The placement groove is symmetrically opened on the dispensing rod 403. The stop block 410 is symmetrically arranged inside the dispensing rod 403. The spring 411 is compressed between the placement groove and the spring 411. The stop block 410 has a large beveled surface corresponding to the piston push block at the surface position near the glue storage plate 401. The stop block 410 is pushed by the piston push block through the large beveled surface. The stop block 410 has a small beveled surface at the surface position away from the glue storage plate 401. The limiting mechanism 41 also includes a blocking plate 412 and a blocking pad 413. The blocking plate 412 is hinged to the free end of the dispensing rod 403. The blocking pad 413 is installed on the blocking plate 412 and fits against the dispensing rod 403.

[0030] When the drive cylinder 406 pushes the push plate 404, thereby causing the piston pusher to move within the dispensing rod 403, the piston pusher will first contact the large beveled surface of the stop block 410 near the surface of the glue storage plate 401. Due to the presence of the large beveled surface, the pushing of the piston pusher will cause the stop block 410 to be subjected to a component force perpendicular to the direction of the large beveled surface. This component force will cause the stop block 410 to overcome the elastic force of the spring 411 and retract into the placement groove. At this time, the spring 411 is further compressed, and the stop block 410 makes way, allowing the piston pusher to continue to move forward and squeeze the glue into the subsequent part of the dispensing rod 403.

[0031] When the glue reaches the free end of the dispensing rod 403 under the push of the piston pusher, the glue will exert a certain pressure on the baffle plate 412. Since the baffle plate 412 is hinged to the free end of the dispensing rod 403, under the action of the glue pressure, the baffle plate 412 will rotate and open around the hinge point, so that the glue can be smoothly squeezed into the glass body. When the glue extrusion stops, the pressure inside the dispensing rod 403 decreases. Under the action of its own weight and the friction generated by the baffle pad 413 and the dispensing rod 403, the baffle plate 412 will return to the position of being in contact with the dispensing rod 403, blocking external dust, impurities and other objects from entering the dispensing rod 403. When the drive cylinder 406 drives the piston pusher to retract, the stop block 410 loses the pushing force of the piston pusher on the large bevel surface. At this time, the compressed spring 411 will restore its elastic deformation, pushing the stop block 410 out of the placement groove, so that it returns to the initial position, ready for the next glue extrusion.

[0032] Furthermore, during the retraction of the piston pusher block driven by the drive cylinder 406, the stop block 410, through the small oblique cut on the other side, can contact the small cut surface on the piston pusher block surface. Because the cut surface is small and there is a contact surface between the two small cut surfaces, the piston pusher block can cooperate with the contact surface of the stop block 410 to pull the glue storage plate 401 backward. During the backward movement of the glue storage plate 401, the support plate 402 gradually moves out of the gap between the two glass bodies. Simultaneously, the support... Plate 402 can work with the conical plate to gradually bring the two glass bodies closer together, avoiding large gaps when directly pulled out, which could cause the glass bodies to collide, resulting in cracks and damage. When the piston pusher moves the glue storage plate 401 to the pusher plate 404 and the glue storage plate 401 is in contact, the pulling force remains unchanged, and the pusher plate 404 cannot move, which allows the small cut surface between the stop block 410 and the piston pusher to gradually fit together. At this time, the piston pusher can be pulled out from the straight rod and the conical rod, and then cooperate with the next glass body bonding.

[0033] By setting up a stop block 410, a spring 411, and a placement groove to cooperate with each other, the piston push block pushes the large oblique surface of the stop block 410, so that the stop block 410 overcomes the elastic force of the spring 411 and retracts into the placement groove to make room. When the piston push block retracts, the spring 411 resets the stop block 410. This achieves the effect of controlling the forward passage of the piston push block during the extrusion process and maintaining a certain structural stability inside the dispensing rod 403 in the non-extrusion state.

[0034] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
