Description

Technical Field

[0001] This invention belongs to the field of eyeglass case manufacturing equipment, and specifically relates to a riveting machine for eyeglass cases. Background Technology

[0002] During the production of eyeglass cases, hinges are used to connect the two halves of the eyeglass case lid. Each of the two hinge blades has a connecting through hole, and each adjacent side of the eyeglass case lid has a bendable sheet-like protrusion. The protrusions on the two eyeglass case lids are passed through the through holes on both sides of the hinge and then bent. The bent protrusions fix the hinge in place, thus allowing the two eyeglass case lids to be installed together.

[0003] When installing the hinge between the two eyeglass case lids, the process is complicated because the protrusion on the eyeglass case lid needs to pass through the through hole on the hinge and bend to press and fix the hinge. Therefore, currently the hinge is assembled to the two eyeglass case lids manually, which is time-consuming, labor-intensive and inefficient. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a riveting machine for eyeglass cases, so as to solve the problem of low work efficiency caused by the current method of manually installing hinges between two eyeglass case lids.

[0007] Furthermore, a box-feeding mechanism is provided in front of the human-shaped guide frame. The box-feeding mechanism includes two third pushers symmetrically arranged around the human-shaped guide frame. The third pushers are used to push the glasses case cover between the inclined push plate and the human-shaped guide frame.

[0008] Furthermore, the box feeding mechanism also includes limiting members and stops on both sides of the pushing end of the third pusher, with the stops positioned on the side of the inclined push plate away from the third pusher along the pushing direction of the third pusher.

[0009] Furthermore, a fixed frame is provided above the humanoid guide frame, and the abutment is fixedly connected to the bottom of the fixed frame. A fourth pusher is provided on the fixed frame. The pushing direction of the fourth pusher is parallel to the length direction of the humanoid guide frame. The pushing end of the fourth pusher is provided with a humanoid push plate that is adapted to the upper part of the humanoid guide frame. The fourth pusher is used to drive the humanoid push plate to move on the humanoid guide frame.

[0010] Furthermore, the frame is provided with a through groove located below the middle of the humanoid guide, the through groove is parallel to the length direction of the humanoid guide, the second pusher is set below the frame through the base plate, the guide column is vertically set between the base plate and the bottom of the frame, the lifting plate is set between the second pusher and the hinge placement frame, the lifting plate is provided with positioning holes that are slidably connected to the guide column, the lifting plate is provided with a fifth pusher for driving the hinge placement frame to move along the length direction of the through groove, and the through groove extends to the front of the humanoid guide.

[0011] Furthermore, the humanoid guide is provided with pressing positions on both sides. The two pressing positions are located on both sides of the pressing interface. The height of the pressing positions on both sides of the humanoid guide is adapted to the height of the first pusher pushing the inclined push plate onto the humanoid guide. The humanoid push plate is located on the side of the inclined push plate away from the pressing positions.

[0012] Furthermore, a pressure plate is provided on the side of the pressing position away from the human-shaped guide frame, and the pressure plate extends upward at an inclined angle along the side of the human-shaped guide frame.

[0013] Furthermore, both ends of the hinge holder are equipped with limiting protrusions.

[0014] Furthermore, a controller is installed on the rack, and the first pusher, second pusher, third pusher, fourth pusher and fifth pusher are all connected to the controller for control.

[0015] The significant advantages achieved by this invention are as follows: This application uses a case-feeding mechanism to deliver the eyeglass case lids to a case-joining mechanism, which then joins the two eyeglass case lids together.

[0016] Furthermore, the bending mechanism moves the hinge and bends the protrusion on the eyeglass case lid to fix the hinge between the two eyeglass case lids, completing the work of installing the hinge on the eyeglass case lid.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figures 1-7 As shown, a riveting machine for eyeglass cases includes a frame 1, with a box-joining mechanism and a bending mechanism installed on the upper end of the frame 1. The box-joining mechanism includes a human-shaped guide frame 2, a first pusher 3, and a V-shaped abutment 4. There are two first pushers 3, which are located on both sides of the human-shaped guide frame 2. The push ends of the two first pushers 3 face the side of the human-shaped guide frame 2. The push ends of the two first pushers 3 are rotatably connected to inclined push plates 10. The two first pushers 3 push the inclined push plates 10 towards the middle human-shaped guide frame 2. Under the action of the push force, the inclined push plates 10 rise along the inclined surfaces on both sides of the human-shaped guide frame 2, thereby merging the two separate eyeglass case lids with the protruding side together. The V-shaped abutment 4 is fixed above the human-shaped guide frame 2 by a fixing bracket 14. The human-shaped guide frame 2 has a pressing interface 5 located below the abutment 4. The bending mechanism is located below the pressing interface 5.

[0026] After the two eyeglass case lids are joined together by the inclined surface of the human-shaped guide 2, the V-shaped sides of the abutment 4 can limit the two eyeglass case lids to form a V-shape, which facilitates the installation of the hinge.

[0027] The bending mechanism includes a V-shaped hinge holder 6 located below the pressure interface 5 and a second pusher 7 for pushing the V-shaped hinge holder 6 toward the abutment member 4. The lower V-shape of the abutment member 4 is adapted to the upper V-shape of the hinge holder 6. After the hinge is placed on the hinge holder 6, it forms a V-shape and is adapted to the lower V-shape of the abutment member 4. The hinge holder 6 has a groove adapted to the through hole on the hinge. One side wall of the groove has a bending protrusion for bending the protrusion on the eyeglass case lid. When the hinge is placed on the hinge... The rear bending protrusion on the mounting bracket 6 is located below the through hole of the hinge and leaves a gap for the protrusion on the eyeglass case lid to enter; when the two eyeglass case lids are joined together to form a V shape and are located above the pressure interface 5, the second pusher 7 drives the hinge mounting bracket 6, on which the hinge is placed, to rise toward the pressure interface 5. As the hinge mounting bracket 6 rises, the protrusions on the two eyeglass case lids respectively enter the hinge through hole on the hinge mounting bracket 6 and bend under the action of the bending protrusion to complete the fixation of the hinge, so that the two eyeglass case lids are connected together by the hinge rotation.

[0028] To facilitate streamlined processing, a case-feeding mechanism is installed in front of the humanoid guide frame 2. This mechanism pushes the eyeglass case lid between the inclined push plate 10 and the humanoid guide frame 2, allowing the lid to be pre-prepared for easier operation. The mechanism includes two symmetrical third pushers 11 centered on the humanoid guide frame 2. These third pushers 11 push the eyeglass case lid between the inclined push plate 10 and the side of the humanoid guide frame 2, facilitating the inclined push plate 10 to push the lid onto the humanoid guide frame 2.

[0029] The pushing direction of the third pusher 11 is parallel to the length direction of the human-shaped guide frame 2. In order to ensure that the glasses case cover moves between the inclined push plate 10 and the side of the human-shaped guide frame 2 under the push of the third pusher 11, the case feeding mechanism also includes limiting members and blocks 13 located on both sides of the pushing end of the third pusher 11. The blocks 13 are installed on the side of the inclined push plate 10 away from the third pusher 11 along the pushing direction of the third pusher 11. In this application, the limiting members include limiting strips 26 and sixth pushers 27. The limiting strips 26 are parallel to the length direction of the third pusher 11, and the pushing direction of the sixth pushers 27 is perpendicular to the length direction of the limiting strips 26. After the glasses case cover is placed in front of the pushing end of the third pusher 11, the sixth pushers 27 push the glasses case cover to make it parallel to the limiting strips 26 to facilitate the pushing of the third pusher 11. The blocks 13 are set to block the glasses case cover pushed by the third pusher component so that the glasses case cover is located between the inclined push plate 10 and the side of the human-shaped guide frame 2.

[0030] After the two eyeglass case lids are connected by hinges, they need to be removed before further processing can proceed. To facilitate subsequent processing and removal of the installed eyeglass cases, a fixing frame 14 is installed above the humanoid guide frame 2. The abutment 4 is fixedly connected to the bottom of the fixing frame 14. A fourth pusher 15 is installed on the upper end of the fixing frame 14. The pushing direction of the fourth pusher 15 is parallel to the length direction of the humanoid guide frame 2. The pushing end of the fourth pusher 15 is equipped with a humanoid push plate 16 that fits with the upper part of the humanoid guide frame 2. The fourth pusher 15 is used to drive the human-shaped push plate 16 to move on the human-shaped guide frame 2. A gap is left between the human-shaped push plate 16 and the human-shaped guide frame 2 to avoid friction between the two affecting the movement of the human-shaped push plate 16. By installing the fourth pusher 15 and the human-shaped push plate 16 above the human-shaped guide frame 2, after the glasses case on the human-shaped guide frame 2 is installed, the fourth pusher 15 drives the human-shaped push plate 16 to move along the length of the human-shaped guide frame 2 to push the glasses case off the human-shaped guide frame 2, which is convenient for subsequent processing.

[0031] To facilitate the placement of hinges onto the hinge holder 6, the frame 1 has a through groove 17 located below the center of the human-shaped guide 2. The through groove 17 is parallel to the length of the human-shaped guide 2 and extends to the front of the human-shaped guide 2. The second pusher 7 is mounted on the base plate 1 below the frame 1, with the pushing end of the second pusher 7 facing the pressure interface 5. The base plate 1 is parallel to the frame 1, and its four corners are fixedly connected to the frame 1 by guide posts 1. A lifting plate 20 is provided between the second pusher 7 and the hinge holder 6. The lifting plate 20 has openings that connect with the guide posts 6. The positioning hole is slidably connected to the column 1. The lifting plate 20 is equipped with a fifth pusher 21 for moving the hinge placement rack 6 along the length direction of the through groove 17. When the hinge needs to be placed on the hinge placement rack 6, the hinge placement rack 6 moves along the through groove 17 away from the bottom of the human-shaped guide frame 2 and moves in front of the human-shaped guide frame 2 to facilitate the placement of the hinge. When the hinge needs to be connected to the glasses case cover, the hinge placement rack 6 is moved back to the bottom of the pressing interface 5 by the fifth pusher 21, and the pressing is completed by the upward push of the second pusher 7.

[0032] To facilitate the installation of the hinges onto the two eyeglass case lids and for continued processing, pressing positions 22 are installed on both sides of the humanoid guide frame 2. The pressing positions 22 are plates inclined along the sides of the humanoid guide frame 2. The two pressing positions 22 are located on both sides of the pressing interface 5. The height of the pressing positions 22 on both sides of the humanoid guide frame 2 is adapted to the height at which the first pushing member 3 pushes the inclined push plate 10 onto the humanoid guide frame 2. A pressure plate 23 is installed on the side of each pressing position 22 away from the humanoid guide frame 2. The pressure plate 23 extends upward along the inclined angle of the side of the humanoid guide frame 2, and the distance between the pressure plate 23 and the side of the humanoid guide frame 2 gradually increases. The humanoid push plate 16 is located on the inclined push plate 1. 0 is away from the side of the pressing position 22; the setting of the pressing position 22 can facilitate the first pusher 3 to merge the two glasses case lids together in advance. After the two first pushers 3 merge the two glasses case lids together through the inclined push plate 10, the fourth pusher 15 drives the human-shaped push plate 16 to move the glasses case lid located between the two inclined push plates 10 to the two pressing positions 22 along the human-shaped guide frame 2. At this time, the two glasses case lids are located below the abutment 4. The setting of the pressure plate 23 can limit the glasses case lids to avoid separation between the two glasses case lids, and facilitate the hinge placement frame 6 to rise and bend the protrusion on the glasses case lid through the pressing interface 5.

[0033] To prevent the hinge from moving freely when the hinge holder 6 moves, limiting protrusions are provided at both ends of the hinge holder 6 along its length. Both limiting protrusions are higher than the top surface of the groove. The limiting protrusions are used to limit the hinge and prevent it from moving freely on the hinge holder 6. The height difference between the top surface of the limiting protrusion and the top surface of the groove is the thickness of the hinge.

[0034] For ease of operation, a controller 25 is installed on the rack 1. The first pusher 3, the second pusher 7, the third pusher 11, the fourth pusher 15, the fifth pusher 21, and the sixth pusher 27 are all connected to the controller 25. The controller 25 is used to control the actions of the first pusher 3, the second pusher 7, the third pusher 11, the fourth pusher 15, the fifth pusher 21, and the sixth pusher 27. The controller 25 is configured to perform automated operation. The controller 25 is equipped with start and stop buttons.

[0035] In this embodiment, the first pusher 3, the second pusher 7, the third pusher 11, the fourth pusher 15, the fifth pusher 21, and the sixth pusher 27 are all cylinders, but they can also be telescopic components such as electric cylinders or electric push rods. Since the pushing distance of the fourth pusher 15 and the fifth pusher 21 is relatively long, parallel guide rails are provided on one side of the fourth pusher 15 and the fifth pusher. The frame 1 is provided with a sliding groove that matches the guide rail. The stable operation of the fourth pusher 15 and the fifth pusher 21 can be ensured by the setting of the guide rail and the sliding groove.

[0036] In operation, the operator places the two eyeglass case lids in front of the pushing ends of the two third pushers 11, with the raised sides of the two eyeglass case lids facing each other. The hinge is then placed on the hinge holder 6 located in front of the humanoid guide frame 2. The start button on the controller 25 is pressed, and the sixth pusher 27 pushes the eyeglass case lids until they are parallel to the limit strip 26, then returns to its original position. After the eyeglass case lids are parallel to the limit strip 26, the two third pushers 11 push the eyeglass case lids between the inclined push plate 10 and the humanoid guide frame 2, then return to their original positions. Simultaneously, the fifth pusher 21 moves the hinge holder 6 back below the pressing interface 5 to await pressing. The two first pushers 3 then use the inclined push plate 10 to merge the eyeglass case lids together along the two sides of the humanoid guide frame 2. Finally, the fourth pusher 15 moves the humanoid push plate 16 towards the pressing position 22. Since the human-shaped push plate 16 is located on the upper part of the human-shaped guide frame 2, and the two eyeglass case covers are merged on the human-shaped guide frame 2, when the human-shaped push plate 16 moves, it will push the two merged eyeglass case covers to the pressing position 22. After the human-shaped push plate 16 moves the eyeglass case covers to the two pressing positions 22, it returns to its original position. The protrusions on the opposite sides of the eyeglass case covers are just above the pressing interface 5. The pushing end of the second pusher 7 moves towards the pressing interface 5, thereby causing the lifting plate 20, the fourth pusher 15 and the hinge placement frame 6 to rise. As the hinge placement frame 6 rises, the protrusions on the two eyeglass case covers enter the through hole on the hinge and bend under the action of the bending protrusion to fix the hinge, thus completing the installation of the two eyeglass case covers and the hinge. After the human-shaped push plate 16 pushes the eyeglass case covers to the pressing position 22, the first pusher 3 drives the inclined push plate 10 to return to its original position to wait for the third pusher component to push the subsequent eyeglass case covers.

[0037] In summary, this application uses a case-feeding mechanism to deliver the eyeglass case lids to a case-merging mechanism, which merges the two eyeglass case lids together. A bending mechanism moves the hinge and bends the protrusions on the eyeglass case lids to fix the hinges between the two lids, thus completing the hinge installation on the eyeglass case lids. The entire process is automated, convenient, and quick, requiring no manual operation. This effectively solves the problem of low work efficiency caused by manually installing the hinges between the two eyeglass case lids.
