Description

Technical Field

[0001] The utility model belongs to the technical field of camera module manufacturing, and particularly relates to a device for scraping residual glue of a camera module. Background Art

[0002] In the production process of a camera module, a relatively important link is the AA (Active Alignment) process of the camera module, which not only affects the assembly stability of the camera module but also affects the lens yield during the finished product test. When problems occur in the produced module and subsequent repair is required, the removed lens and the lens holder will be adhered with residual AA glue at the connection, and it will not be possible to put it into production again, which wastes the production resources of the lens and increases the manufacturing cost of the module.

[0003] In view of the above problems, the existing solutions generally adopt manual scraping or physical methods for removal. However, the manual scraping method greatly increases the cost of removing residual glue and the labor intensity of workers, and cannot guarantee the product yield after scraping; while the physical method for removal generally uses special tooling fixtures, such as using a crank-slider mechanism to pull the handle to push the blade on the slider to remove the residual glue on the lens holder. However, most of the common physical glue removal tooling fixtures on the market are often two different machines for scraping the lens holder and the lens, and cannot adapt to camera modules of different models. Especially for the residual glue on the lens, the problem of avoiding damage to the lens during the glue removal process needs to be considered. Therefore, a device for scraping residual glue of a camera module that can be compatible with scraping the lens holder and the lens and can ensure the glue removal quality is proposed.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field of the present application. The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0031] As Figures 1-5 shown, a device for scraping residual glue of a camera module is applied to a camera module. The camera module includes a lens and a lens holder. The device for scraping residual glue of the camera module includes a base 1, a linear motion unit, a scraping unit 3, and a rotating clamping unit 5, where:

[0032] The scraping unit 3 includes a support base 31, an adjusting unit, and a tool 34. The support base 31 is installed on the base 1. The adjusting unit is installed on the support base 31 and is used to achieve the Y-direction and Z-direction adjustment of the tool 34. The tool 34 is used to remove glue from the sample 6 to be degummed. The sample 6 to be degummed is a lens or a lens holder.

[0033] The rotating clamping unit 5 includes a rotating support base 51, a turntable sleeve 52, a turntable 53, and a clamp 54. The rotating support base 51 is installed on the base 1. The turntable sleeve 52 is connected to the rotating support base 51. The turntable 53 is connected to the turntable sleeve 52 and is used to drive the clamp 54 to rotate around the X-axis. The clamp 54 is used to clamp the sample 6 to be degummed.

[0034] The linear motion unit is installed on the base 1 and is used to achieve the X-direction movement of the support base 31, so as to make the tool 34 abut against the sample 6 to be degummed or move away from the sample 6 to be degummed.

[0035] The above orientations are only for easy understanding and description and are not specifically limited. For example, the X-direction is the left-right direction, the Y-direction is the front-back direction, and the Z-direction is the up-down direction.

[0036] As Figure 1As shown in the figure, the device mainly consists of three parts: the glue scraping part (scraping unit 3), the linear reciprocating part (linear motion unit), and the rotating clamping part (rotating clamping unit 5). Through the cooperation of these three parts, the removal of residual glue on the lens or lens holder is achieved. The glue scraping part is responsible for removing the residual glue; and in cooperation with the linear reciprocating part, it is responsible for the compatibility with lens holders or lenses of different sizes; the rotating clamping part is responsible for providing the power for rotation.

[0037] As Figure 4 shown, the turntable sleeve 52 is a ring structure. There is a sunk groove on the rotating support base 51. The turntable sleeve 52 is located in the sunk groove. There are also two bosses on the outer wall of the turntable sleeve 52. It is fixedly connected to the rotating support base 51 by screws passing through the bosses, which is convenient for disassembly, installation, and maintenance. The rotating support base 51 and the turntable sleeve 52 can also be integrally designed. The rotating support base 51 is installed on the base 1 with bolts. The rotating support base 51 is parallel to the support base 31.

[0038] The cutter 34 moves closer to or away from the sample 6 to be degummed along the linear motion unit. During degumming, the lens holder or lens clamped by the fixture 54 is driven by the turntable 53 to rotate around the X-axis, and the cutter 34 contacts the residual glue on the lens holder or lens to remove the residual glue.

[0039] In an embodiment, the fixture 54 includes a clamping main body 541, a first clamping plate 542, a second clamping plate 543, a limiting plate 544, and two springs. Both the first clamping plate 542 and the second clamping plate 543 are slidably connected to the clamping main body 541. The limiting plate 544 is connected to the clamping main body 541 and is provided with two limiting grooves 546. There are also limiting bosses 545 on each clamping plate. The limiting bosses 545 are inserted into the limiting grooves 546. The springs are respectively located in the limiting grooves 546 and their two ends are respectively connected to the limiting grooves 546 and the limiting bosses 545. The clamping main body 541 is connected to the turntable 53 and is provided with a groove for matching and positioning the sample 6 to be degummed. Through the elastic action of the springs, the relative movement or reverse movement of the first clamping plate 542 and the second clamping plate 543 is realized, so as to realize the blocking and fixing or loosening of the sample 6 to be degummed.

[0040] As Figure 5As shown, the fixture 54 is preferably a special fixture for the lens holder. There is a groove on the clamping body 541 that adapts to the bottom shape of the lens holder. The lens holder is placed on the groove to complete the initial positioning of the lens holder; the first clamping plate 542 and the second clamping plate 543 are installed on the installation groove of the clamping body 541 for fixing the lens holder; the limiting plate 544 is fixed on the side of the clamping body 541, and the limiting groove 546 on the limiting plate 544, the limiting boss 545 on the clamping plate and the spring are used to realize the limiting of the corresponding clamping plate. The spring is preferably a compression spring. During operation, the limiting boss 545 on the corresponding clamping plate is pushed to push open the clamping plate, the spring is compressed, the groove on the clamping body 541 is exposed, the lens holder is placed on the groove, the limiting boss 545 is released, and the spring resets, driving the corresponding clamping plate to reset to complete the fixing of the lens holder.

[0041] It is easy to understand that the fixture 54 can also be adaptively adjusted according to the sample 6 to be degummed, such as adjusting the shape and size of the groove on the clamping body 541 that adapts to the shape of the sample 6 to be degummed, or replacing the entire fixture 54 to be compatible with the lenses and lens holders of different models of camera modules.

[0042] In one embodiment, the linear motion unit is a lead screw nut mechanism;

[0043] Or the linear motion unit includes a guiding unit 2 and a locking unit 4, where:

[0044] The guiding unit 2 is used to guide the X-direction movement of the support base 31 to enable the tool 34 to approach or move away from the sample 6 to be degummed; the locking unit 4 is used to realize the locking and limiting of the support base 31 when the tool 34 degums the sample 6 or to realize the loosening adjustment of the support base 31 after degumming.

[0045] Among them, the tool 34 can be directly driven and adjusted by a lead screw nut mechanism, such as the lead screw being a T-shaped lead screw or a ball screw. Or the linear motion unit composed of the guiding unit 2 and the locking unit 4 respectively performs the guiding and locking functions. For example, the tool 34 approaches or moves away from the sample 6 to be degummed along the guiding unit 2, and the locking and limiting or loosening adjustment are carried out through the locking unit 4. During degumming, the lens holder or lens clamped by the fixture 54 is driven by the turntable 53 to rotate around the X-axis, and the tool 34 contacts the residual glue on the lens holder or lens to remove the residual glue.

[0046] In one embodiment, the guiding unit 2 includes a plurality of parallel optical rods 21 and at least one fixed seat 22. The fixed seat 22 is installed on the base 1, the optical rod 21 passes through the support base 31, and one end is connected to the fixed seat 22 and the other end is connected to the rotating support seat 51.

[0047] In one embodiment, the locking unit 4 includes two lock heads, and the lock heads pass through any one of the optical rods 21 and are respectively located on both sides of the support base 31.

[0048] The linear reciprocating part consists of a guiding unit 2 and a locking unit 4, including two optical rods 21, two fixed seats 22, and two lock heads, as Figure 2 shown. One end of the optical rod 21 is fixed to the base 1 through the fixed seat 22, and the other end is threaded and fixed to the threaded hole of the rotating support seat 51. The optical rod 21 also passes through the through hole on the support seat 31. The lock heads are respectively installed on the same optical rod 21 and are located on both sides of the support seat 31. One side of the lock head restricts the distance between the tool 34 and the sample 6 to be de-glued, and the other side of the lock head restricts the movement of the tool 34, so as to remove the residual glue for mirror bases or lenses of different sizes. The lock head is a prior art structure, such as a quick lock head for optical rods of the FL series selected.

[0049] In one embodiment, the adjusting unit includes a sliding seat 32 and an adjusting seat 33. A sliding groove is provided on the support seat 31 along the Y direction. A sliding rail is provided on the sliding seat 32 and is slidably connected to the sliding groove. A plurality of kidney-shaped holes are provided on the adjusting seat 33, and the adjusting seat 33 is connected to the sliding seat 32 through screws passing through the kidney-shaped holes.

[0050] As Figure 3 shown, a sliding groove is provided on the support seat 31, and the sliding rail is slidably connected to the sliding groove (such as a T-shaped groove) to achieve Y-direction adjustment. The adjusting seat 33 installed with the tool 34 is fixed to the sliding seat 32 through screws. A plurality of kidney-shaped holes are provided on the adjusting seat 33 to achieve Z-direction adjustment of the tool 34. By adjusting the Y-direction and Z-direction movement of the tool 34, the working radius of the tool 34 is adjusted so that it can scrape the residual glue on mirror bases and lenses of different sizes. It is easy to think that the adjusting unit can also be replaced with a biaxial moving mechanism in the prior art.

[0051] In one embodiment, the tool 34 is detachably connected to the adjusting seat 33. The tool 34 is prone to damage or glue cleaning, and the detachable connection facilitates replacement and maintenance.

[0052] In one embodiment, the adjusting unit further includes a limiting unit for limiting the Y-direction movement of the sliding seat 32. The working stability of the tool 34 is ensured through the limiting unit.

[0053] In one embodiment, the limiting unit includes two screws, and the two screws respectively abut against both ends of the sliding rail and are connected to the support seat 31. Or it can also be replaced by other simple structures that are easy to think of by those skilled in the art, such as limiting through a set screw passing through the sliding seat 32 or limiting by a linear guide rail with a locking function.

[0054] In one embodiment, the rotating clamping unit 5 further includes a crank 55 and a bearing. The bearing is coaxially arranged between the turntable 53 and the turntable sleeve 52, and the turntable 53 is driven to rotate by the crank 55. The bearing helps to reduce friction and facilitate the rapid rotation of the turntable 53. The crank 55 and the clamp 54 are respectively located on both sides of the turntable 53. Rotating the crank 55 causes the turntable 53 and the clamp 54 connected thereto to rotate together. The clamp 54 drives the clamped lens holder or lens to rotate, and the tool 34 contacts the residual glue on the lens holder or lens to remove the residual glue. It is easy to think that the crank 55 can also be replaced by a motor drive or the like.

[0055] Working principle:

[0056] The locking unit 4 is loosened, and the support base 31 is pushed away from the rotating clamping unit 5. By pushing the limit boss 545 on the corresponding clamping plate, the clamping plate is pushed open, the spring is compressed, and the groove on the clamping main body 541 is exposed. The sample 6 to be degummed is placed on the groove. After loosening the limit boss 545, the spring resets to drive the corresponding clamping plate to reset, completing the fixation of the sample 6 to be degummed. After the support base 31 is pushed close to contact the sample 6 to be degummed, it is locked and fixed by the locking unit 4. Rotating the crank 55 causes the turntable 53 to rotate and drive the clamp 54 to rotate, thereby driving the sample 6 to be degummed to rotate. The tool 34 contacts the residual glue on the sample 6 to be degummed to remove the residual glue. After degumming is completed, the locking unit 4 loosens the support base 31, and the support base 31 is pushed away from the rotating clamping unit 5. By pushing the limit boss 545 on the corresponding clamping plate, the clamping plate is pushed open, the spring is compressed, and the groove on the clamping main body 541 is exposed. The sample 6 to be degummed is taken out and a new sample 6 to be degummed is put in. Repeating the above operations can complete the degumming operation of different samples 6 to be degummed.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0058] The above-described embodiments only represent the embodiments of the present application that are described more specifically and in detail, but should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
