Technical Field

[0001] The utility model relates to a square lens adhesive backing positioning jig, belonging to the technical field of square lens processing. Background Art

[0002] When manufacturing optical components, two or more lenses need to be bonded together. At this time, the adhesive backing needs to be bonded to the lenses before bonding multiple lenses.

[0003] When bonding the adhesive backing to the lens, manual bonding is generally used. However, manual bonding requires extremely high manual skills and is difficult to position. It can easily cause the adhesive backing to deviate from the outer edge of the square lens and is inefficient.

[0004] Therefore, in order to solve the above problems and improve work efficiency, a square lens adhesive backing positioning fixture is urgently needed. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a square lens adhesive backing positioning jig. When positioning the square lens with adhesive backing, the upper cover plate, the adhesive backing plate and the bottom plate are first stacked in sequence from top to bottom. When stacking, it is necessary to ensure that the bonding position corresponds to the square receiving groove, so that the position of the lens can be controlled by the square receiving groove, so that all the lenses are attached to the bonding position, and rapid positioning can be achieved. Since a semicircular notch is provided on each square receiving groove, it is convenient to discharge the bottom air when the lens to be bonded is placed at the bonding position, thereby achieving a close fit between the bonding position and the lens.

[0006] In order to achieve the above purpose / solve the above technical problems, the present invention adopts the following technical solutions:

[0009] The length and width of the bottom plate and the upper cover plate are consistent;

[0010] During positioning, the upper cover plate, the adhesive-backed plate and the bottom plate are stacked in sequence from top to bottom.

[0011] Furthermore, the upper cover plate, the adhesive-backed plate and the bottom plate are all provided with pin holes for pins to penetrate.

[0012] Furthermore, the length of the adhesive-backed plate is consistent with that of the upper cover plate, and the width of the adhesive-backed plate is smaller than that of the upper cover plate.

[0013] Furthermore, it also includes grooves, which are opened on both sides of the middle part of the bottom plate.

[0014] Furthermore, the number of the bonding positions and the number of the square receiving grooves are both five.

[0015] Furthermore, the length and width of the square receiving groove are both 0.1 mm higher than the lens to be bonded.

[0016] Furthermore, the four corners of the square receiving groove are chamfered.

[0017] Furthermore, the bonding position includes a square groove and an adhesive edge, the square groove is adapted to the lens to be bonded, and the length of the square groove is consistent with the lens to be bonded, and the width is 0.1mm less than the product to be bonded, and the adhesive edge is bonded to the edge of the square groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The utility model provides a square lens adhesive backing positioning jig. When positioning the square lens for adhesive backing, the upper cover plate, the adhesive backing plate and the bottom plate are first stacked in sequence from top to bottom. When stacking, it is necessary to ensure that the bonding position corresponds to the square receiving groove, so that the position of the lens can be controlled by the square receiving groove, so that all the lenses are attached to the bonding position, and rapid positioning can be achieved. Since a semicircular notch is provided on each square receiving groove, it is convenient to discharge the bottom air when the lens to be bonded is placed on the bonding position, thereby achieving close adhesion between the bonding position and the lens.

[0028] like Figures 1 to 4 As shown, this embodiment provides a square lens adhesive backing positioning fixture, including an upper cover plate 1, an adhesive backing plate 2 and a bottom plate 3, wherein:

[0029] The adhesive backing plate 2 is provided with a plurality of bonding positions 4, and the upper cover plate 1 is provided with a square receiving groove 5 adapted to the bonding position 4, and semi-cylindrical notches 6 are provided on both sides of the square receiving groove 5;

[0030] The length and width of the bottom plate 3 and the upper cover plate 1 are consistent;

[0031] During positioning, the upper cover plate 1 , the adhesive-backed plate 2 and the bottom plate 3 are stacked in sequence from top to bottom.

[0032] In the above technical solution, when positioning the square lens with adhesive backing, the upper cover plate 1, the adhesive backing plate 2 and the bottom plate 3 are first stacked in sequence from top to bottom. When stacking, it is necessary to ensure that the bonding position 4 corresponds to the square receiving groove 5, so that the position of the lens can be controlled by the square receiving groove 5, so that all the lenses are attached to the bonding position 4, and rapid positioning can be achieved. Since a semicircular notch 6 is provided on each square receiving groove 5, it is convenient to discharge the bottom air when the lens to be bonded is placed at the bonding position 4, thereby achieving a close fit between the bonding position 4 and the lens. Example 2

[0033] The square lens adhesive backing positioning jig provided in this embodiment differs from the square lens adhesive backing positioning jig provided in Example 1 in that:

[0034] like Figures 2 to 4 As shown, in order to facilitate the positioning and fixing of the upper cover plate 1, the adhesive-backed plate 2 and the bottom plate 3 when they are stacked, the upper cover plate 1, the adhesive-backed plate 2 and the bottom plate 3 are all provided with pin holes 7 for pins to penetrate.

[0035] The length of the adhesive-backed plate 2 is consistent with that of the upper cover plate 1 , and the width of the adhesive-backed plate 2 is smaller than that of the upper cover plate 1 .

[0036] like Figure 4 As shown, in order to facilitate the subsequent disassembly of the stacked upper cover plate 1 , adhesive-backed plate 2 and bottom plate 3 , grooves 8 are also included. The grooves 8 are opened on both sides of the middle of the bottom plate 3 .

[0037] In this embodiment, the number of the bonding positions 4 and the square receiving grooves 5 are both five, which can complete the bonding of five lenses at the same time, but is not limited to this, and can also be other numbers, which can be adjusted according to actual conditions.

[0038] In order to facilitate the placement of the lens to be bonded through the square receiving groove 5, the length and width of the square receiving groove 5 are both 0.1 mm higher than the lens to be bonded.

[0039] In order to reduce the need for manual work and ensure that the lens is easily placed in place, the four corners of the square receiving groove 5 are chamfered.

[0040] like Figure 3 As shown, the bonding position 4 includes a square groove 9 and a back adhesive edge 10. The square groove 9 is adapted to the lens to be bonded, and the length of the square groove 9 is consistent with the lens to be bonded, and the width is 0.1mm lower than the product to be bonded. The back adhesive edge 10 is bonded to the edge of the square groove 9.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
