Detailed Description
The present invention is further described below in conjunction with the drawings and the embodiments so that those skilled in the art can better understand the present invention and can carry out the present invention, but the embodiments are not to be construed as limiting the present invention.
Referring to fig. 1, the method for pneumatically pressing a lens of the present invention to achieve alignment pressing of the lens and a lens includes the following steps:
the product with the lens is fixed on the mobile platform 1, when the mobile platform 1 bears the product, the position of the product relative to the mobile platform 1 is fixed, the product can move to drive the mobile platform 1 to move synchronously, and the mobile platform 1 can move in a self-adaptive mode in cooperation with the product.
The periphery of camera lens is pasted and is applied magnetic pole spacing piece 3, magnetic pole spacing piece 3 surround the camera lens seted up with the endocentric through-hole 31 of camera lens, refer to fig. 2 and show, the camera lens of this embodiment is circular camera lens, and according to the imaging principle, most of camera lenses all adopt circular camera lens, the selection requirement of magnetic pole spacing piece 3 is: the diameter of the through hole 31 is larger than that of the circular lens, and the magnetic pole limiting sheet 3 is pasted in the following way: the through hole 31 and the circular lens are concentrically applied, the center of the lens is the center of the through hole 31, and in order to ensure that the magnetic field distribution outside the magnetic pole limiting sheet 3 is the same, it is required to ensure that the areas of the magnetic pole limiting sheets 3 positioned in all directions outside the circular lens are the same, according to the requirements on the magnetic pole limiting sheets 3, the shape of the magnetic pole limiting sheet 3 preferably selected in the embodiment should be circular, one side surface of the magnetic pole limiting sheet 3 is a back adhesive surface, so that the magnetic pole limiting sheet 3 can be concentrically applied to the periphery of the lens, and the specific application mode can be manual application or automatic equipment application;
specifically, in the stamping process, in order to prevent the magnetic stamping head 24 from being pressed against the periphery of the magnetic pole limiting piece 3 under the action of repulsion force, the diameter of the magnetic pole limiting piece 3 needs to be 3-5 times of the diameter of the through hole 31.
Set up pneumatic press 2 that is used for punching press lens in the top of camera lens, the punching press head that sets up pneumatic press 2 be with the magnetic punching press head 24 of the spacing piece 3 with the magnetic pole of magnetic pole, promptly when the magnetic pole of the spacing piece 3 of magnetic pole is the N utmost point, magnetic punching press head 24 also sets up to the N utmost point, when the magnetic pole of the spacing piece 3 of magnetic pole is the S utmost point, magnetic punching press head 24 also sets up to the S utmost point.
The pneumatic press machine 2 drives the magnetic punch head 24 to move towards the lens, the magnetic punch head 24 and the magnetic pole limiting sheet 3 gradually approach to each other, in the approach process, the moving platform 1 is pushed to move horizontally through the magnetic force, the magnetic punch head 24 penetrates through the center of the through hole 31 of the magnetic pole limiting sheet 3, the magnetic punch head 24 abuts against the center of the lens, as shown in figure 3, the magnetic punch head 24 on the pneumatic press machine 2 is arranged above the lens, the position of the magnetic punch head 24 cannot exceed the periphery of the magnetic pole limiting sheet 3, the stress state when the magnetic punch head 24 and the magnetic pole limiting sheet 3 approach to each other is analyzed from one side, when the magnetic punch head 24 deviates from the center position above the magnetic pole limiting sheet 3 and abuts against the magnetic pole limiting sheet 3, due to the principle that like poles repel each other, in the process of approaching gradually, the repulsive force between the magnetic punch head 24 and the magnetic pole limiting sheet 3 gradually increases, the magnetic punching head 24 is prevented from approaching to the direction of the magnetic pole limiting sheet 3, but the horizontal position of the magnetic punching head 24 is not changed under the driving of the pneumatic press 2 and gradually approaches to the direction of the magnetic pole limiting sheet 3, therefore, in the process of approaching gradually, a part of the repulsive force is converted into a horizontal component force pushing the magnetic pole spacing sheet 3, because the magnetic pole spacing piece 3 is pasted on the product which is fixedly arranged on the moving platform 1, the horizontal component force can push the moving platform 1 to move, so that the magnetic pole spacing piece 3 moves in the direction far away from the magnetic punching head 24 in the horizontal direction, so that the magnetic punching head 24 is moved toward the center position of the pole-holding piece 3 with respect to the pole-holding piece 3, because the lens and the magnetic pole limiting sheet 3 are concentrically arranged in the above steps, the magnetic pole limiting sheet 3 moves to the central position of the lens relative to the lens;
after the magnetic stamping head 24 relatively moves to the central position of the lens, the distance between the magnetic stamping head 24 and the magnetic pole limiting sheet 3 in any direction is the same, so that the horizontal component force received by each position in the horizontal direction is the same, the directions are opposite, the magnetic pole limiting sheet 3 does not receive component force in the horizontal direction any more, the moving platform 1 stops moving, the magnetic stamping head 24 is driven by the pneumatic press machine 2 to penetrate through the center of the magnetic pole limiting sheet 3, the magnetic stamping head 24 is pressed at the center of the lens, and the accuracy of the pressing position is ensured.
The sizes of the lenses set for different products are slightly different, and for the lenses with different sizes, the diffusion distances of adhesive materials between the lenses are different, so that when the lenses with different sizes are pressed, the required pressing force is different, the lenses are easily damaged due to too large pressing force, the lenses are incompletely pressed due to too small pressing force, and the lenses fall off from the lenses, so that the pressing force of the pneumatic press machine 2 can be adjusted in the embodiment, and the pneumatic press machine 2 determines to adjust different pressing forces according to the sizes of the pressed lenses; moreover, according to different customer requirements, different viscous coefficients are caused by different viscous materials coated between the lens and the lens, namely, the time for bonding and cooling has a certain difference, so that when the lens made of different viscous materials is pressed, the required pressing time is different, the pressing time is too long, the production efficiency of the whole line is reduced, and the problems of incomplete pressing and falling of the lens from the lens occur in too long pressing time, therefore, the pressing time of the pneumatic press machine 2 arranged in the embodiment can be adjusted, and the pneumatic press machine 2 determines to adjust different stamping times according to the bonding materials of the lens and the lens.
Specifically, the required pressing force is specifically analyzed for the lens size of the product:
the pressing force is F:
F=(D/D0)F0
wherein D is0Base lens diameter, F0The pressing force of the diameter of the basic lens is used, and D is the actual diameter of the lens;
the specific analysis process is as follows: selecting a base lens diameter D0The lens is 1cm, the lens is pressed by different pressing forces, the pressing effect is tested after pressing is finished, and the critical point of the pressing force, namely the value that the lens and the lens cannot be separated after pressing, is determined through multiple pressing tests, and is the pressing force F of the diameter of the basic lens0；
Then, changing the diameter of the lens, pressing the lenses with different diameters, testing the pressing effect after the pressing is completed, measuring the values of critical points with different diameters, which can meet the pressing effect, and fitting and establishing a functional relation according to the values of the critical points and the diameters of the lenses to obtain a pressing force F:
F=(D/D0)F0
that is, the lens diameter and the pressing force are in a proportional relationship, and the pressing force required is larger as the lens diameter is larger.
Specifically, the stitching time required for specifically analyzing the magnitude of the viscosity coefficient of the viscous material is as follows:
the pressing time is T:
T=(K0/K)2T0
wherein, K0Based on the viscosity coefficient, T0The pressing time of the basic viscosity coefficient is taken as K is the viscosity coefficient;
the specific analysis process is as follows: selecting a basic viscosity coefficient as 1Pa s, stitching the lens by adopting different stitching time, testing the stitching effect after stitching is finished, and determining a critical point of the stitching time through a plurality of stitching tests, namely the value of the lens and the lens which are not separated after stitching, wherein the critical point is the stitching time of the basic viscosity coefficient;
then, carry out the pressfitting to the camera lens of the adhesive material laminating of different viscosity coefficients, test the effect of pressfitting after the pressfitting is accomplished, survey the value that the adhesive material of different viscosity coefficients can satisfy the critical point of pressfitting effect, establish the functional relation with the value fitting of different viscosity coefficients and critical point, obtain pressfitting time T:
T=(K0/K)2T0
that is, the larger the viscosity coefficient is in inverse relation to the press-fitting time, the shorter the press-fitting time is required, and according to the above relation, when the lens to be bonded with the material is pressed, the corresponding bonding coefficient can be input to obtain the required press-fitting time.
