Description

Technical Field

[0001] The utility model relates to the technical field of dispensing equipment, and particularly relates to an inclined dispensing mechanism. Background Art

[0002] In the manufacturing process of optical lenses, the dispensing process is a key technology, which is widely used for the fixation and sealing of lens components. The dispensing valve precisely extrudes the glue through the dispensing needle, and applies the glue to the element to be dispensed through the glue outlet, so as to realize the fixed connection between the elements. Especially when performing circular dispensing on the inner wall of holes of workpieces such as lens barrels, the accuracy and uniformity of the dispensing process have a crucial impact on the performance and reliability of the lens.

[0003] The existing dispensing technology mainly relies on a vertical dispensing gun, and completes circular dispensing by rotating the dispensing gun annularly along the inner wall of the hole of the workpiece (such as a lens barrel). However, this method has various difficulties and deficiencies in actual operation:

[0004] Uneven glue distribution: Since the glue is easily affected by gravity during vertical dispensing, the glue distribution is uneven during circular dispensing. This uneven glue distribution will affect the dispensing effect, thereby affecting the fixing strength and sealing performance between the elements.

[0005] Dispensing deviation: During vertical dispensing, the glue is prone to being dispensed crookedly and cannot accurately cover the entire circular area. This situation requires patching in subsequent processes, increasing the complexity and time cost of the operation.

[0006] Therefore, there is an urgent need for a dispensing device that can effectively solve the deficiencies in the existing technology. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0024] As shown Figure 1-2 in the figure, an inclined dispensing mechanism according to this embodiment includes a rotating assembly for rotating the dispenser 1 annularly and a fine displacement device for translating the dispenser 1; the output end of the rotating assembly is provided with the fine displacement device; the fine displacement device is connected to the dispenser 1 through a mounting plate 5; an angle adjusting mechanism for adjusting the inclination angle of the dispenser 1 is provided between the dispenser 1 and the mounting plate 5; the output end of the dispenser 1 rotates annularly around the rotation axis of the rotating assembly.

[0025] Due to the setting of the angle adjusting mechanism, the dispenser 1 vertically arranged in the prior art can be inclined so that the axis direction of the dispenser is inclined with respect to the rotation axis of the rotating assembly. After the dispenser is inclined by a certain angle, therefore, the glue outlet of the dispenser 1 can better fit the inner wall of the hole of the workpiece (such as a lens barrel), making the glue dispensing between the adhered workpieces (such as lenses) more uniform, with good dispensing effect and no need for rework. In addition, since the traditional dispenser 1 is directly connected to the output end of the rotating assembly, the position of the dispenser 1 is relatively fixed. Therefore, when facing products of different models that need to be dispensed, it is often necessary to adjust the position of the workpiece to be processed to cooperate with the dispensing head. For some small workpieces, high adjustment accuracy is required. By setting the fine displacement device, the dispenser 1 can be moved back and forth, left and right. Therefore, whether during debugging or actual production, the position of the dispenser 1 can be adjusted with high precision.

[0026] As shown Figure 1-2 in the figure, an inclined dispensing mechanism according to this embodiment, the fine displacement device includes a first fine adjustment mechanism for moving the dispenser 1 back and forth and a second fine adjustment mechanism for moving the dispenser 1 left and right; the first fine adjustment mechanism is connected to the second fine adjustment mechanism; the mounting plate 5 is arranged on the second fine adjustment mechanism.

[0027] The above setting can quickly adjust the position of the dispenser 1 in four directions, and the adjustment method is intuitive and fast.

[0028] As shown Figure 1-2 in the figure, an inclined dispensing mechanism according to this embodiment, the first fine adjustment mechanism includes a first locking assembly, a first fixing block 211 connected to the output end of the rotating assembly, and a first slider 212 slidably connected to the first fixing block 211; the first locking assembly is used to lock the first fixing block 211 and the first slider 212; the second fine adjustment mechanism includes a second fixing block 221 connected to the first slider 212 and a second slider 222 slidably connected to the second fixing block 221; the mounting plate 5 is arranged on the second slider 222.

[0029] Specifically, the mounting plate 5 and the second slider 222 can be integrally provided. A slide rail is provided between the first fixed block 211 and the first slider 212, and a slide rail is provided between the second fixed block 221 and the second slider 222. When it is necessary to move the dispenser 1 back and forth, first unlock the first locking assembly so that the first fixed block 211 and the first slider 212 can slide along the slide rail. Move the first slider 212. When the first slider 212 drives the dispenser 1 to reach the target position, lock the first locking assembly to fix the position of the dispenser 1 in the current direction. Similarly, a second locking assembly (not shown in the figure) for locking the second fixed block and the second slider can be additionally provided; the second locking assembly includes a second bolt, a second locking piece, and a second strip-shaped hole; the second strip-shaped hole is provided on the second locking piece; one end of the second bolt passes through the second strip-shaped hole and is threadedly connected to the second fixed block 221; similarly, by loosening or tightening the second bolt, the second slider 222 can be locked or unlocked. By unlocking or locking the second locking assembly and then moving the second slider 222, the position of the dispenser 1 in the current direction can be locked.

[0030] As Figure 1-2 shown, in an inclined dispensing mechanism of this embodiment, the first locking assembly includes a first bolt 213, a first locking piece 214, and a first strip-shaped hole 215; the first locking piece 214 is provided on the first slider 212; the first strip-shaped hole 215 is provided on the first locking piece 214; one end of the first bolt 213 passes through the first strip-shaped hole 215 and is threadedly connected to the first fixed block 211.

[0031] When it is necessary to unlock the first slider 212, only need to loosen the first bolt 213, and the first slider 212 can be moved back and forth to the specified position; the first strip-shaped hole 215 is used to limit the moving distance of the first slider 212 to prevent the first slider 212 from slipping; when it is necessary to lock the first slider 212, only need to tighten the first bolt 213.

[0032] As Figure 1-2 shown, in an inclined dispensing mechanism of this embodiment, a first differential head 216 is provided on the first fixed block 211; the movable end of the first differential head 216 is connected to the first slider 212; a second differential head 223 is provided on the second fixed block 221; the movable end of the second differential head 223 is connected to the second slider 222.

[0033] The first differential head 216 and the second differential head 223 can precisely adjust the position of the dispenser 1, which is applicable when processing small workpieces or workpieces with high precision requirements. Specifically, by turning the fixed end of the first differential head 216, its movable end can drive the first slider 212 to move forward and backward with high precision correspondingly. By turning the fixed end of the second differential head 223, its movable end can drive the second slider 222 to move forward and backward with high precision correspondingly.

[0034] As Figure 1-2 shown, an inclined dispensing mechanism of this embodiment, the angle adjustment mechanism includes a rotating plate 31, a rotating shaft 32 and a third bolt 33; the rotating plate 31 is rotatably connected to the mounting plate 5 through the rotating shaft 32; the dispenser 1 is arranged on the rotating plate 31; an arc-shaped hole 34 is further arranged on the rotating plate 31; the third bolt 33 passes through the arc-shaped hole 34 and is threadedly connected to the mounting plate 5.

[0035] Specifically, the rotating shaft 32 and the third bolt 33 are both installed on the mounting plate 5; when the position of the dispenser 1 needs to be adjusted, loosen the third bolt 33 so that the rotating plate 31 can swing along the rotating shaft 32, thereby driving the dispenser 1 to swing by a certain angle, and then tighten the third bolt 33 to fix the dispenser 1 at the current position, and the arc-shaped hole 34 can limit the rotation amplitude of the rotating plate 31.

[0036] As Figure 1-2 shown, an inclined dispensing mechanism of this embodiment, a tension spring 35 is arranged between the mounting plate 5 and the dispenser 1.

[0037] Specifically, one end of the tension spring 35 can be arranged on the dispenser 1, and the other end of the tension spring 35 can be arranged on the mounting plate 5, which is used to reset the dispenser 1 and prevent the dispenser 1 from falling.

[0038] As Figure 1-3 shown, an inclined dispensing mechanism of this embodiment, the rotating assembly includes a hollow rotating table 41, a connecting block 42 and a driving member 43; the driving member 43 is used to drive the output end of the hollow rotating table 41 to rotate; the connecting block 42 is installed on the output end of the hollow rotating table 41; the micro-displacement device is installed on the connecting block 42; a fixed air pipe 44 is arranged in the middle through hole of the hollow rotating table 41; an L-shaped air pipe 45 is arranged in the connecting block 42; one end of the L-shaped air pipe 45 is communicated with the fixed air pipe 44; the other end of the L-shaped air pipe 45 is connected to the dispenser 1 through a connecting pipe.

[0039] Specifically, the connecting block 42 is connected to the first fixing block 211. Since the trachea of the dispenser 1 is easily entangled with parts when the dispenser 1 rotates annularly for dispensing, a through hole is provided in the middle of the hollow rotary table 41, and then the fixed trachea 44 is placed in the through hole for connecting to the external trachea. Therefore, the gas of the external trachea can pass through the fixed trachea 44, the L-shaped trachea 45, and the connecting pipe in sequence to reach the dispenser 1. During operation, the driving member 43 drives the hollow rotary table 41 to drive the connecting block 42 to rotate. Since the L-shaped trachea 45 is arranged in the connecting block 42, when the connecting block 42 rotates, it drives the micro-displacement device and the dispenser 1 to rotate together. The L-shaped trachea 45 and the connecting pipe (not shown in the figure) are relatively stationary and no trachea torsion problem will occur.

[0040] As Figure 1-2 shown, in an inclined dispensing mechanism of this embodiment, a bushing (not shown in the figure) is provided between the rotating plate 31 and the rotating shaft 32; a washer 36 is provided between the third bolt 33 and the rotating plate 31.

[0041] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structures, features, and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
