Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] refer to Figure 1-2 A positioning fixture for eyeglass eyeglasses adhesive includes: a base 1, a positioning mold 2, and a frame pressing assembly 3. The base 1 has a fixing groove 11. The positioning mold 2 is embedded in the fixing groove 11 and has a positioning groove 21 for positioning an eyeglass frame 6. The frame pressing assembly 3 has a pressing member 31 that is vertically adjustable on the base 1 and located above the positioning mold 2, for pressing the eyeglass frame 6 into the positioning groove 21. Several positioning molds 2 are prepared, and each positioning mold 2 has a different size positioning groove 21 to correspond to positioning eyeglass frames 6 of different sizes.

[0021] Understandably, base 1 is the supporting and mounting base component. The fixing groove 11 can be located in the middle of base 1 or on the top side of base 1. The positioning mold 2 and positioning groove 21 are fitted together, for example, they can be square or round, but are not limited to these shapes. Positioning groove 21 can position half of the eyeglass frame 6 or the entire eyeglass frame 6. The height adjustment of the pressing component 31 can be achieved using a screw for height adjustment, or by using a shaft hole structure for vertical guidance, combined with an elastic element to press down the pressing component 31. Alternatively, it can be automatically raised and lowered using a cylinder or electric push rod, but is not limited to these methods. The pressing component can be a rod or a plate, but is not limited to these methods.

[0022] With this setup, the eyeglass frame 6 can be positioned horizontally by embedding it into the positioning groove 21, which is more accurate than manual placement. The frame pressing component 3 can then press the eyeglasses together, ensuring the stability of the position of the eyeglass frame 6 and thus guaranteeing the accuracy and uniformity of the glue application for each eyeglass frame 6. Several positioning molds 2 are prepared, which can be replaced according to the size of the eyeglass frame 6, thus increasing the applicability. Moreover, the positioning molds 2 are embedded and positioned through the fixing groove 11, making replacement simple and convenient.

[0023] In some embodiments, the fixing groove 11 is provided on the top side of the base 1, forming an inlet 111 with the side of the base 1. With this configuration, when installing the positioning mold 2, the positioning mold 2 can be inserted into the fixing groove 11 through the inlet 111 for positioning, making installation more convenient.

[0024] Furthermore, the fixing groove 11 and the positioning mold 2 are respectively provided with positioning holes 4, and the positioning mold 2 is positioned by inserting a pin 5 into the positioning hole 4. Understandably, while the setting of the pin 111 makes the installation of the positioning mold 2 more convenient, it may cause the positioning mold 2 to move. The positioning hole 4 and the pin 5 cooperate to lock the positioning mold 2 and prevent it from shifting. Of course, the cooperation between the positioning hole 4 and the pin 5 can also be replaced by the cooperation between a threaded hole and a bolt 312.

[0025] In some embodiments, the positioning groove 21 is disposed on the top side of the positioning mold 2 to position the half-frame on the eyeglass frame 6. It is understandable that during the glue application process, only one side of the eyeglass frame 6 can be processed at a time, and the other side requires conversion of the eyeglass frame 6. Therefore, the positioning groove 21 only needs to position the half-frame of the eyeglass frame.

[0026] In some embodiments, the pressure frame assembly 3 includes a mounting base 32 and a lifting drive 33. The mounting base 32 is liftably mounted on the base 1 and located on one side of the positioning mold 2; the top of the mounting base 32 is provided with a plurality of mounting positions 321 arranged at intervals along the horizontal and vertical directions connecting the mounting base 32 and the positioning mold 2. The output end of the lifting drive 33 is connected to the mounting base 32 and is used to drive the mounting base 32 to rise and fall. The pressure member 31 is detachably mounted on one of the mounting positions 321.

[0027] It is understandable that the height-adjustable setting of the mounting base 32 can be directly raised and lowered by the lifting drive component 33, or it can be equipped with a shaft hole or slide rail for auxiliary guidance, but is not limited to these. The detachable setting of the mounting position 321 and the pressure component 31 can be achieved by threaded engagement of the threaded hole of the bolt 312 or by snap-fit ​​connection, but is not limited to these. The lifting drive component 33 can be fixedly mounted on the base 1, or it can be mounted on the body, ground, or other components outside of this utility model. The lifting drive component 33 can be a cylinder or an electric push rod, but is not limited to these.

[0028] With this configuration, the pressure member 31 can be installed in different mounting positions 321 as needed, thereby adjusting the position of the pressure member 31 pressing down on the eyeglass frame and ensuring the stability of pressing down on the eyeglass frame 6.

[0029] In some embodiments, reference Figure 1 and Figure 3 The base 1 has a guide hole 12, and the mounting base 32 is vertically guided by a guide rod 322 inserted into the guide hole 12. One or more guide holes 12 and guide rods 322 can be provided. This guiding engagement between the guide hole 12 and the guide rod 322 improves the stability of the mounting base 32 during lifting.

[0030] In some embodiments, the mounting position 321 is a threaded hole, and the clamping member 31 is fixed by a bolt 312 engaging with the threaded hole. Furthermore, the clamping member 31 has an elongated through groove 311, through which the bolt 312 passes and is locked in the threaded hole.

[0031] With this configuration, the engagement of the through groove 311 and the bolt 312 allows the pressure member 31 to be moved and rotated, thereby precisely adjusting the position of the pressure member 31 pressing down on the eyeglass frame 6.

[0032] In some embodiments, two frame pressing components 3 are provided, located on both sides of the positioning mold 2. Thus, two frame pressing components 3 provide two pressing members 31, which simultaneously press on the eyeglass frame 6, covering a wider area and providing more stable compression.

[0033] Furthermore, the two pressing pieces 31 press onto the adjacent edges of the eyeglass frame 6. Specifically, the two pressing pieces 31 press onto the two adjacent edges of the eyeglass frame 6 at the post position. Here, the adhesive application is located at the post position of the eyeglass frame 6, so pressing onto the two adjacent edges at the post position provides greater stability.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
