Description
Technical Field
The invention relates to a jig and a method for auxiliary positioning, in particular to a vacuum auxiliary inspection jig with an adsorption function, which is applied to a camera module and related supporting industries, and a manufacturing and using method thereof.
Background
The camera module is widely applied to different products, such as mobile phone cameras, photographic equipment and the like, and the camera module is an indispensable part in various image acquisition devices.
Along with the requirement of image acquisition equipment to the image quality of gathering is higher and higher, the function and the precision degree of the module of making a video recording are also expanding and improving constantly. Generally, the function of the camera module is expanded or the precision is improved in not only two major aspects, but also brand new development of the components of the device itself, such as development of new materials and new structures; on the other hand, on the basis of the prior art, the accuracy of each part is improved, such as the yield of the parts, the matching relation among the parts and the like.
In both respects, the theoretical design is superior to the manufacturing technique due to the degree of development of the prior art. Many technologies, theoretical design has reached a very high level, and it is difficult to make a new breakthrough, and much perplexing is whether the manufacturing technology can accurately realize the designed device performance.
In the manufacturing process of the camera module and the related equipment, the detection process is one of the indispensable steps, and the detection accuracy directly affects the performance of the whole equipment after being applied to the image module equipment, so that one of the basic problems is how to ensure the rapidness and the accuracy of the detection.
For a general detection process, a basic detection environment is firstly provided, so that the product can truly reflect the characteristics of the product. If the basic detection environment is provided, the product can not accurately or quickly reflect the real self performance, on one hand, false detection can be caused to influence the overall detection rate, and on the other hand, the product can be detected by adjusting, so that more working hours are consumed certainly, and the production efficiency is reduced. It is therefore important to provide a basic detection environment that ensures accurate and rapid detection.
In the testing process of current module of making a video recording, to the part that need not seal the detection, generally all directly place in a dull and stereotyped tool, the main problem that exists to this kind of dull and stereotyped tool is exactly the fixed problem to the product. That is to say, after the product is placed on the tool that is located the below of check out test set, on the one hand, the roughness of product can't guarantee. As is well known, the flatness is visually important for the image imaging result, and affects whether the light irradiates the product and then reflects the light entering the detection device, thereby affecting whether the detection device can work normally or whether the detection device can collect the proper image information of the detected workpiece. In the prior art, due to the influence of flatness, a focusing knob of a detection lens needs to be adjusted for many times in the detection process so as to enable the imaging of a product to be clear. In the process, the detection conditions of the product are different due to the difference of adjustment, and the multiple adjustment processes require technical support and consume more time, so that the yield of the product, the detection of the product or the production efficiency are influenced.
Another aspect of the fixation problem is that the detection of the central position cannot be guaranteed. That is to say, after the detection workpiece is placed on the jig for plate alignment, it cannot be guaranteed whether the position to be detected and the relative position of the detection lens are proper or not, whether the horizontal direction has a deviation or not, and if the deviation exists, the position needs to be adjusted.
In addition, due to no fixing measures, the position of the product is easily influenced by external interference in the detection process, for example, workers touch the product by mistake in the operation process, so that the detection of the product is possibly influenced and is not easy to find.
In addition to the fixation problem, the convenience of the worker's operation is also an important aspect. In the production process of the lens module or the related components, many processes are in line. That is, after a process is finished, a worker may be required to quickly move a product to a position, so that the provided jig should facilitate manual operation, whereas most of the provided jigs in the prior art are only a flat plate and do not provide a position suitable for manual operation.

Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
The vacuum adsorption technology is that vacuum negative pressure is used to form pressure difference on two sides of workpiece so as to reach the aim of adsorbing and fixing the workpiece. The workpiece fixing device is mainly applied to the aspects of lifting, conveying and the like of workpieces, but generally applied parts are workpieces with larger volumes or workpieces with larger hardness, so that the adsorption force can not influence the fixed workpieces. The fixing problem in the field of designing precise elements such as camera modules always troubles the production detection process, but more requirements are provided for the fixing mode due to the precision of the camera modules.
Fig. 1 is a schematic diagram of a detection environment in the prior art. Briefly illustrating the detection environment provided by the prior art: a detection fixture 100 is placed on a working table 200, and a detection lens 300 is arranged above the detection fixture 100. In the detection process, a workpiece 1 to be detected is placed on the detection fixture 100, and the detection lens 300 acquires an image of the detected workpiece 1, so as to detect and judge the quality of the workpiece 1. After the workpiece 1 is qualified, a part 2, such as a mirror seat, is dipped in glue or other adhesive in a glue groove 3, so that the part 2 is fixed on the workpiece 1; after the component 2 is adhered, if necessary, the detection is continued through the monitoring lens, such as water wave, corner collapse, dirt and the like after the lens base is adhered. And after all the detection operations are finished, taking the workpiece 1 away by a worker, and continuously detecting the next workpiece 1.
Referring to fig. 2 to 10, the present invention provides a vacuum auxiliary inspection jig, which can be connected to a vacuum generator 400 to adsorb and fix a workpiece 1 to the vacuum auxiliary inspection jig. The vacuum auxiliary inspection jig comprises a jig body 10, wherein the jig body 10 is provided with at least one vacuum suction hole 11, and each vacuum suction hole 11 can be communicated with the vacuum generator 400 so as to adsorb and fix the workpiece 1 on the jig body 10.
It should be noted that the vacuum generator 400 may be any device capable of assisting the vacuum auxiliary inspection jig in working, so that when the workpiece 1 is placed on the vacuum auxiliary inspection jig, the inner side and the outer side of the workpiece 1 above the position of the vacuum suction hole 11 generate air pressure difference.
It should be further appreciated by those skilled in the art that the vacuum generator 400 can assist the vacuum-assisted inspection tool in generating a vacuum absorption effect. It is worth mentioning that the vacuum referred to herein is only a certain vacuum level, and a differential pressure vacuum can be generated, and an absolute vacuum is not required.
The vacuum auxiliary inspection jig further comprises a cover plate 20, the cover plate 20 is connected below the jig body 10 and forms a communicating chamber 30 with the jig body 10, and the communicating chamber 30 is communicated with each vacuum suction hole 11. That is, the communication chamber 30 communicates with the external space through each of the vacuum suction holes 11.
The jig body 10 has a groove 12, the groove 12 is disposed at the bottom of the jig body 10, that is, at a position opposite to each vacuum suction hole 11, and the cover plate 20 is accommodated in the groove 12. The jig body 10 further includes a set of connection bosses 13, the set of connection bosses 13 are oppositely disposed in the groove 12, and the cover plate 20 is connected to the connection bosses 13 to form the communication chamber 30. That is, the cover plate 20 is received in the connecting boss 13 fixed in the groove 12 at the bottom of the jig body 10, so that the communication chamber 30 is formed between the cover plate 20 and the bottom of the jig body 10, and each vacuum suction hole 11 is communicated with the communication chamber 30.
Further, the cover plate 20 may be fixedly connected to the connection boss 13, and the connection boss 13 forms a square boss structure along the inner wall of the groove 12 of the jig body 10. According to a preferred embodiment of the present invention, it is implemented that the cover plate 20 is fixedly connected to the square connection boss 13 by means of glue bonding, the connection boss 13 forms the communication chamber 30 with a sealed bottom, and the upper part of the communication chamber 30 is in gas communication with the external space through the vacuum suction hole 11.
Further, the size of the cover plate 20 matches the size of the opening of the recess 12 so that the cover plate 20 is received within the recess 12. It should be noted that according to a preferred embodiment of the present invention, the depth of the groove 12 is greater than the sum of the thickness of the cover plate 20 and the thickness of the connection boss 13. That is to say, after the cover plate 20 is connected to the connecting boss 13, the groove 12 has a remaining space, and when the vacuum auxiliary inspection jig is placed on a working table, a predetermined distance is provided between the bottom of the cover plate 20 and the working table, so that the cover plate 20 does not directly contact with the placed working table, thereby reducing the friction area between the vacuum auxiliary inspection jig and the working table, and reducing the friction dust generation in the process of taking and placing the vacuum auxiliary inspection jig.
It is worth mentioning that in the process of manufacturing the camera module industry and related products, due to the requirements of manufacturing precision and special performance of the camera module industry and the related products, the production environment is very important to the production process, and some dust-free environments are definitely specified, so that the friction area is reduced, dust generated in the friction process is reduced, and the beneficial effect is achieved on ensuring the production environment, and the detection and production process of workpieces is ensured.
The jig body 10 further comprises a set of support ribs 19, and the set of support ribs 19 is located at the bottom of the jig body 10 and is used for supporting the vacuum auxiliary inspection jig. That is to say, when the vacuum auxiliary inspection tool is placed on the worktable, the supporting ribs 19 are in direct contact, so that the group of supporting ribs 19 reduces the contact area between the vacuum auxiliary inspection tool and the worktable, thereby reducing the friction area in the process of taking and placing the vacuum auxiliary inspection tool, enabling the worker to take and place the vacuum auxiliary inspection tool more conveniently, reducing dust generated due to friction, and ensuring a good detection environment. Furthermore, the supporting ribs 19 may be disposed at the edge of the bottom of the jig body 10, that is, the supporting ribs 19 protrude from the bottom of the jig body 10, so that a concave space is formed inside the supporting ribs 19, and the bottom of the jig body 10 inside the supporting ribs 19 does not directly contact the working table, thereby reducing the friction area between the vacuum auxiliary inspection jig and the working table, and reducing the dust generated by friction.
It should be noted that the supporting ribs 19 may be implemented to be continuously distributed at the bottom of the jig body 10, alternatively, the supporting ribs 19 may be distributed at intervals at the bottom of the jig body 10, so as to reduce the contact area between the supporting ribs 19 and the working table while stably supporting the vacuum auxiliary inspection jig.
The jig body 10 further has a vacuum groove through hole 14, and the vacuum groove through hole 14 is communicated between the communicating chamber 30 and an external space, that is, the communicating chamber 30 can be in gas communication with the outside through the vacuum groove through hole 14. Further, the inner end of the vacuum groove through hole 14 communicates with the communicating chamber 30, and the outer end of the vacuum groove through hole 14 is adapted to be connected to the vacuum generator 400. When the vacuum generator 400 operates, the vacuum generator 400 sucks the gas in the communicating chamber 30 through the vacuum groove through-hole 14.
The jig body 10 further has an air pipe interface 141, the air pipe interface 141 is suitable for communicating with the vacuum generator 400, and the air pipe interface 141 is communicated with the vacuum groove through hole 14, so that the vacuum groove through hole 14 is in air communication with the vacuum generator 400.
It is noted that the vacuum slot through hole 14 may be a through channel, such that the gas on both sides of the vacuum slot through hole 14 may be communicated through the through channel of the vacuum slot through hole 14. Correspondingly, the two sides of the vacuum groove through hole 14 can respectively correspond to one air pipe joint hole 141, so that the two sides of the vacuum groove through hole 14 can be connected to the vacuum generator 400, thereby facilitating the communication of the vacuum generator 400 at different positions in different working environments, and improving the gas extraction speed when the two ends are simultaneously connected to the vacuum generator 400. Alternatively, either side of the vacuum vessel through-hole 14 may be blocked off the air connector hole 141 with a first blocking member so that only one end of the air connector hole 141 may be connected to the vacuum generator 400. The first blocking element can be embodied as a blocking screw.
Referring to fig. 8, which is a schematic view illustrating an adsorption unit of the vacuum auxiliary inspection jig according to a preferred embodiment of the present invention, each of the vacuum suction holes 11 of the jig body 10 is communicated with the communication chamber 30 to form an adsorption unit, and the communication chamber 30 is communicated with the vacuum generator 400 through the vacuum groove through hole 14, thereby forming an adsorption structure. When the workpiece 1 is placed on the jig body 10, the vacuum generator 400 sucks the gas, so that the gas in the vacuum groove through hole 14 and the communicating chamber 30 communicated with the vacuum groove through hole is reduced, a pressure difference is formed between the upper side and the lower side of the workpiece 1 corresponding to the position of each vacuum sucking hole 11, and a negative pressure difference is formed between the gas pressure P1 on the upper side of the workpiece 1 and the gas pressure P2 on the lower side of the workpiece 1. That is, a negative pressure is formed at the lower side of the workpiece 1 through the vacuum suction hole 11, thereby sucking the workpiece 1 to the jig body 10. When the gas in the through hole 14 of the vacuum tank and the outside are restored to balance, the pressures on the inner side and the outer side of the workpiece 1 are restored to balance, and the adsorption force applied to the workpiece 1 disappears. In the processes of adsorption and desorption, acting force generated by gas has small influence on the workpiece 1. That is, neither the suction nor the suction releasing process affects the relative position of the workpiece 1 on the jig body 10.
Furthermore, the plurality of vacuum suction holes 11 of the jig body 10 are uniformly distributed in the jig body 10, so that the workpiece 1 is uniformly adsorbed in the adsorption process, and the workpiece 1 can be flatly adsorbed and fixed on the jig body 10. More specifically, the size of the vacuum suction hole 11 is set to a predetermined size so that the work 1 can be smoothly sucked and fixed during the suction process without causing deformation of the work 1 due to excessive suction force or unstable fixation or other adverse factors due to insufficient suction force. The aperture size of the vacuum suction hole 11 may be determined according to the performance of inspecting the workpiece 1.
The jig body 10 is further provided with a vacuum hole 15, and the vacuum hole 15 is communicated with the vacuum groove through hole 14 and used for forming or releasing the adsorption effect of the vacuum suction hole 11. That is, the vacuum hole 15 is in gas communication with the adsorption structure, when adsorption needs to be generated, the vacuum releaser 400 operates and simultaneously needs to seal the vacuum hole 15, and when adsorption fixation needs to be released, the vacuum hole 15 is opened, so that the vacuum hole 15 is in gas communication with the outside, and adsorption can be released. In other words, the vacuum hole 15 has the function of controlling the operation of the adsorption structure, and has the effect of opening and closing.
Referring to fig. 9, it is worth mentioning that the vacuum hole 15, the communication chamber 30 and the vacuum groove through hole 14 are in gas communication with each other to form a gas passage, so that the gas in the communication chamber 30 is in gas communication with the outside air through the vacuum hole 15 and the vacuum groove through hole 14. It is understood that the position of the vacuum hole 15 may be set at any position communicating with the communication chamber 30 and/or the vacuum groove through hole 14 according to the requirement, and is not limited to the position and communication manner shown in the figure. When the component 1 is placed on the vacuum auxiliary inspection jig, the vacuum broken hole 15 is blocked, and the gas in the communication chamber 30 is only in gas communication with the vacuum generating device 400, so that the vacuum adsorption effect can be generated; when the vacuum hole 15 is opened, the gas in the communication chamber 30 is simultaneously communicated with the vacuum generator 400 and the external gas, and the vacuum suction effect cannot be obtained.
According to a preferred embodiment of the present invention, the vacuum groove through hole 14 is disposed at an edge position convenient for manual operation, when the workpiece 1 is placed on the jig body 10 in a state of being adsorbed, a worker manually plugs the vacuum hole 15, so that air in the communicating chamber 30 is not communicated with outside air, and when the vacuum generator 400 sucks gas, negative pressure is formed at the inner side and the outer side of the workpiece 1, and the workpiece 1 is adsorbed and fixed; when the detection is finished and the workpiece 1 does not need to be adsorbed, the worker releases his hand, so that the gas in the vacuum groove through hole 40 is communicated with the external gas through the vacuum broken hole 15, the gas in the communication chamber 30 is balanced with the air above the workpiece 1, and the adsorption effect on the workpiece 1 is eliminated. It can also be seen that the worker can complete the processes of adsorption fixation and release fixation of the workpiece only by simple operation, for example, placing a finger at the opening position of the vacuum broken hole 15, and plugging the finger, so that the operation is simple, and the working efficiency is improved.
It should be noted that the blocking manner of the vacuum hole 15 is not limited to the manual blocking manner, and may be implemented as a second blocking element 151, the second blocking element 151 is adapted to block the opening position of the vacuum hole 15, when the workpiece 1 needs to be fixed by suction, the second blocking element 151 blocks the vacuum hole 15, and when the fixing needs to be released, the second blocking element 151 is removed.
The jig body 10 further comprises at least one blocking table 16, and the blocking table 16 is arranged above the jig body 10, is located at the side position of the vacuum suction hole 11, and is used for blocking the workpiece 1. That is, the blocking table 16 protrudes from the fixture body 10 to form a limiting groove with the fixture body 10, and when the workpiece 1 is placed along the fixture body 10, the workpiece 1 is blocked at the position of the blocking table 16, so that the workpiece 1 is placed at a desired position at one time, and the detection position of the workpiece 1 is determined, and meanwhile, the workpiece 1 is prevented from further unnecessary movement.
It should be noted that according to a preferred embodiment of the present invention, the position of the blocking platform 16 can be set as required, for example, for the convenience of the worker, the blocking platform 16 is set in the right hand direction of the worker according to the setting of the working position. That is, in the operation process, the worker puts in the workpiece 1 from the left side, the workpiece 1 is blocked at the blocking table 16, and after the detection is finished, the worker takes the workpiece 1 from the right side, so that the operation is more convenient, and the operation is suitable for the flow line operation.
When the vacuum auxiliary inspection jig is applied to the working environment shown in fig. 1, a worker places the workpiece 1 on the vacuum auxiliary inspection jig along the stop table 16 of the jig body 10 and a limit groove formed by the jig body 10, and the stop table 16 is arranged so that the position of the workpiece 1 corresponds to the position of the detection lens 300, thereby reducing the movement of the workpiece 1. The vacuum generator 400 works, the workpiece 1 is adsorbed and fixed on the jig body 10 by each adsorption unit, and the adsorption force enables the workpiece 1 to be flatly fixed on the vacuum auxiliary inspection jig, so that the detection lens 300 can quickly and accurately acquire the detection information of the workpiece 1 without adjusting the detection lens 300 for many times. Meanwhile, after the workpiece 1 is adsorbed and fixed on the vacuum auxiliary inspection jig, the workpiece 1 is prevented from being unnecessarily moved in the detection process of the detection lens 300.
The jig body 10 further comprises a glue groove portion 17, wherein the glue groove portion 17 is arranged at the side edge position of the jig body 10 and used for containing an adhesive, so that a worker can conveniently adhere the component 2 to the workpiece 1. It is worth mentioning that the arrangement of the glue groove part 17 facilitates the staff to obtain the adhesive, and facilitates the continuous working operation, thereby improving the working efficiency. The glue groove portion 17 has at least one glue groove 171, and the glue groove 171 is used for accommodating an adhesive, such as glue or a fixing member.
