Description

Technical Field

[0001] This invention belongs to the field of hinge assembly technology, and specifically relates to an automatic hinge assembly device. Background Technology

[0002] Hinges, also known as hinges, are usually two-fold hinges. Common hinges are found on cabinet doors, windows, and doors. They are components that connect two parts of an object and allow them to move, and are used to open cabinet doors to a certain angle.

[0003] Currently, most hinges on the market are ordinary hinges. Ordinary hinges have a simple structure, typically consisting of a pair of metal blades connected by a pin. In use, the shaft is inserted into the pivot hole to allow the hinge to rotate, and then flat ends are pressed into both ends. However, because the shaft and pivot hole are in direct contact, and the pivot holes of the two blades are distorted due to the manufacturing process and the physical properties of metal springback, significant friction is generated when the hinge rotates. This affects the smoothness of the hinge's rotation and, over time, greatly impacts its lifespan. To eliminate this friction and extend the hinge's lifespan, there are generally two methods: one is to add resistance oil to the shaft of the ordinary hinge before inserting it into the pivot hole, using the lubrication of the resistance oil to eliminate friction; the other is to add a damping sleeve or plastic sleeve at the hinge shaft position to reduce the friction generated by the hinge's rotation and protect the hinge. However, hinges themselves do not have the property of relieving friction. If too much resistance oil is added, it will flow out of the hinge. If too little resistance oil is added or it is not added in time, the hinge will still be subject to friction when rotating, which will cause wear on the hinge.

[0004] Therefore, existing technologies tend to favor the second method for further protection of the hinge structure. However, regardless of whether it's a damping sleeve or a plastic sleeve, both need to be installed before the hinge is put into use. Most installations on the market are done manually, which, due to the instability of manual work, easily leads to product inconsistencies, causing rework and significantly reducing production efficiency. Summary of the Invention

[0005] In view of this, the present invention provides an automatic hinge assembly device, which can solve the problem of installing the hinge plastic sleeve and realize the automatic assembly of the hinge, thereby effectively improving production efficiency.

[0006] This invention is achieved through the following technical solutions:

[0007] An automatic hinge assembly device includes a worktable, a feeding mechanism, a pressing mechanism, a pressing mechanism, a transfer mechanism, and a control mechanism. The worktable includes a housing, a rotating mechanism, and two rotating platforms. The rotating mechanism is located at the top of the housing, and the two rotating platforms are symmetrically and parallelly arranged above the housing via the rotating mechanism. Tooling mechanisms for clamping leaf blades are provided at the edges of the top surfaces of the two rotating platforms. The two tooling mechanisms can be rotated to face each other via the rotating platforms to complete the hinge assembly. The feeding mechanism includes a frame, a vibrating plate for adhesive particles, and an adhesive particle installer. The frame is located around the housing, and the vibrating plate for adhesive particles is placed on the frame with its opening aligned with the edge of the rotating platform. The adhesive particle installer is fixed to the housing and installed around the opening of the vibrating plate for adhesive particles. When the rotating platform drives the tooling mechanisms to rotate to face each other... When the vibrating disc for the rubber particles opens, the installation and fixing of the rubber particles on the blades is automatically completed; the pressing shaft mechanism is set on the housing, and its open end is aligned with the middle position between the two rotating platforms. When the rotating platform rotates to the point where the two tooling mechanisms are opposite each other, the installation of the hinge shaft core is completed; the pressing plate mechanism is set on the housing and aligned with the pressing shaft mechanism; the transfer mechanism includes a translation mechanism, an lifting mechanism, and a lowering mechanism. The translation mechanism is set on the housing, the lifting mechanism is set on the top of the translation mechanism near the pressing plate mechanism, and the lowering mechanism is set on the end of the translation mechanism near the rotating platform and placed below the tooling mechanism. It is used to support the hinge with the shaft core installed; the control mechanism is electrically connected to the rotating mechanism, the feeding mechanism, the pressing shaft mechanism, the pressing plate mechanism, and the transfer mechanism respectively, and controls the operation of the control device.

[0008] Compared with the prior art, the present invention has at least the following technical effects:

[0009] This invention, through the coordinated arrangement of multiple components such as a rotating platform, a feeding mechanism, a pressing shaft mechanism, and a pressing plate mechanism, allows the hinge to be automatically assembled after being processed by each component. The hinge is then moved by a transfer mechanism, and the control mechanism regulates the entire device to achieve automatic assembly of the hinge. This transforms manual assembly into a more relaxed, fully automated mechanical production process. It features a high degree of mechanization, fast assembly speed, and high product quality stability, effectively improving production efficiency while significantly reducing production costs, making it suitable for widespread use.

[0010] Furthermore, the pressing mechanism includes a shaft frame and a pushing cylinder. The pushing cylinder is fixed on the housing and aligned with the center position between the two rotating platforms. The shaft frame is arranged around the pushing cylinder and provides the hinge shaft core.

[0011] Furthermore, the tablet pressing mechanism includes a flat-head vibrating plate and a sealing cylinder. The sealing cylinder is fixed on the housing, and its opening is linearly aligned with the push-shaft cylinder. The flat-head vibrating plate is arranged around the sealing cylinder and has two outlet ends. The two outlet ends are arranged opposite to each other and are flush with the opening surface of the sealing cylinder.

[0012] Furthermore, the control mechanism includes a motor and a control panel. The motor is disposed inside the housing, and the control panel is vertically disposed on the housing and electrically connected to the motor. The motor and the control panel are respectively electrically connected to the rotating mechanism, the feeding mechanism, the pressing shaft mechanism, the pressing plate mechanism, and the transfer mechanism.

[0013] Furthermore, the device also includes a feeding mechanism, which comprises a feeding robot and a conveyor belt, arranged around the tableting mechanism.

[0025] Please see Figure 1-3 This embodiment provides an automatic hinge assembly device, including a worktable, a feeding mechanism, a pressing mechanism, a pressing mechanism, a transfer mechanism, and a control mechanism;

[0026] Specifically, the workbench includes a housing 1, two rotating mechanisms 2, and two rotating platforms 3. The two rotating mechanisms 2 are respectively located on opposite sides of the top of the housing 1, with one end inside the housing 1 and the other end protruding from the top surface of the housing 1. Both rotating platforms 2 are circular plates. The bottom surface of the rotating platform 3 is fixed on the corresponding rotating mechanism 2, and the rotating platform 3 is then arranged parallel above the housing 1. A tooling mechanism 4 is provided at the top edge of the rotating platform 3. The rotating platform 2 drives the rotating platform 3 to rotate, so that the tooling mechanisms 4 on the two rotating platforms 3 can correspond to each other. The tooling mechanism 4 is provided with a clamping component, which can clamp the hinge blades. The two rotating mechanisms 3 are fixed at the top of the housing 1 so that after the two rotating platforms 3 rotate, the distance between the two opposite tooling mechanisms 4 is exactly the width of the hinge.

[0027] Specifically, the feeding mechanism includes a frame 18, a granule vibrating plate 5, and a granule installation machine 6; the frame 18 is set on both sides of the housing 1, the granule vibrating plate 5 is placed on the frame 18, and the opening of the granule vibrating plate 5 is aligned with the edge of the rotating platform 3; granules are provided to the tooling mechanism 4; the granule installation machine 6 is installed and fixed on the housing 1 around the opening of the granule vibrating plate 6, and when the rotating platform 3 drives the tooling mechanism 4 to rotate to align with the opening of the granule vibrating plate 5, the granule installation machine 6 automatically completes the installation of the hinge blade granules;

[0028] Specifically, the pressing mechanism includes a shaft frame 8 and a pushing cylinder 7. The function of the pushing cylinder 7 is to push the shaft core into the already assembled hinge blades. The pushing cylinder 7 is fixed on the housing 1 and aligned with the middle position between the two rotating platforms 3. When the rotating platform 3 rotates to the point where the two tooling mechanisms 4 are opposite each other, the blades on the two tooling mechanisms 3 are assembled. After the assembly is completed, the pushing cylinder 7 pushes the shaft core in to obtain the hinge. The shaft frame 8 is used to store the hinge shaft core, and the shaft cores are automatically arranged in the shaft frame 8 and sorted and sent to the hinge to be installed one by one. The shaft frame 8 is set above the position between the pushing cylinder 7 and the two rotating platforms 3, and its opening is on the plane of the opening end of the pushing cylinder 7, so that the pushing cylinder 7 can directly push the shaft core.

[0029] Specifically, the tablet pressing mechanism includes a flat-head vibrating plate 10 and a sealing cylinder 9; the sealing cylinder 9 is used to seal the two ends of the hinge, it is fixed on the housing 1 and linearly aligned with the push-shaft cylinder 9; the flat-head vibrating plate 10 is located near the sealing cylinder 9, it has two opposing openings, the bottom of the openings are horizontally set on the opening end plane of the sealing cylinder 9, and the distance between the two openings is slightly greater than the length of the hinge.

[0030] Specifically, the transfer mechanism includes a translation mechanism 11, an lifting mechanism 13, and a lowering mechanism 12. The translation mechanism 11 is mounted on the housing 1 and installed between the push-shaft cylinder 7 and the sealing cylinder 9, with its two ends facing the push-shaft cylinder 7 and the sealing cylinder 9 respectively. The function of the translation mechanism 11 is to transfer the position of the hinge to complete the sealing of the hinge end. The lowering mechanism 12 is located at one end of the translation mechanism 11 near the top surface of the rotating platform 3 and below the corresponding two tooling mechanisms 4, supporting... The hinge; the lifting mechanism 13 is installed at the top of the translation mechanism 11 near the opening of the sealing cylinder 9; after the hinge completes the shaft installation, the lower support mechanism 12 moves down, the hinge enters the translation mechanism 11, is carried by the translation mechanism 11 to the other end, slides into the upper support mechanism 13, and is lifted by the upper support mechanism 13 to the opening surface of the sealing cylinder 9. At this time, the two ends of the hinge are aligned with the two openings 101 of the flat-head vibrating plate 10, and the sealing cylinder 9 presses the flat head into the port of the hinge to complete the sealing of the hinge.

[0031] Specifically, the control mechanism includes a motor and a control panel 16. The motor is installed inside the housing 1, and the control panel 16 is vertically installed on the housing 1. The motor and the control panel are electrically connected to the rotating mechanism, the tooling mechanism 4, the granule vibrating plate 5, the granule installation machine 6, the shaft frame 8, the push shaft cylinder 7, the flat-head vibrating plate 10, the sealing cylinder 9, the translation mechanism 11, the lifting mechanism 13, and the lowering mechanism 12, respectively. At the same time, the control panel 16 is electrically connected to the motor. A PLC controller is installed in the control panel 16 to set parameters and control the operation of the entire device.

[0032] In this embodiment, as Figure 2 As shown, four tooling mechanisms 4 are evenly arranged around the top edge of the rotating platform 3, which can meet the assembly of four hinges at one time.

[0033] In this embodiment, a feeding robot 14 and a conveyor belt 15 are also provided near the tableting mechanism. The feeding robot 14 and the conveyor belt 15 are electrically connected to the motor and the control panel 16, respectively. The feeding robot 14 picks up the assembled hinges and puts them onto the conveyor belt 15 for transport to the next process.

[0034] Based on the above scheme, the assembly process of this device is as follows:

[0035] First, the operator places the two hinge blades onto the tooling mechanisms 4 of the two rotating platforms 3 and clamps them. After clamping, the motor is started, and the rotating platforms 3 begin to rotate, moving the tooling mechanisms 4 to the corresponding positions of the feeding mechanism. The adhesive installation machine 6 automatically picks up the material and installs it. After installation, the rotating platforms 3 continue to rotate. When the two tooling mechanisms 4 are facing each other, the tooling mechanisms 4 push the blades horizontally out, and the two blades are joined together by the lower support mechanism 12. After joining, the push shaft cylinder 7 automatically pushes the shaft core into place. At the hinge joint, the lower support mechanism 12 moves down, and the hinge flows to the translation mechanism 11. The translation mechanism 11 moves to the other end face, and the hinge slides to the lifting mechanism 13. The lifting mechanism 13 lifts the hinge to the port face of the sealing cylinder 9. The translation mechanism 11 returns to perform the operation of the next hinge. At the same time, the sealing cylinder 7 pushes the flat head to press into the port of the hinge, completing the sealing of a hinge. Finally, the lifting mechanism 13 moves down, driving the assembled hinge down. The unloading robot 14 grabs the hinge and places it on the conveyor belt 15 to enter the next process.

[0036] Therefore, the automatic hinge assembly device provided by this invention achieves automatic hinge assembly through the cooperation of multiple components such as a rotating platform 3, a feeding mechanism, a pressing shaft mechanism, a pressing plate mechanism, and a control mechanism. The entire assembly process only requires one person to operate, transforming manual assembly into a more relaxed fully automated mechanical production. The assembly speed is fast, with an average of 4 seconds to complete the assembly of one hinge. The product quality is highly stable. At the same time, multiple tooling mechanisms 4 are set on the rotating platform 3, and multiple feeding mechanisms are set up to support multi-station synchronous operation. In addition, the feeding mechanism uses a vibrating plate 5 to achieve automatic directional feeding, which has a high degree of mechanization and can greatly reduce labor costs.

[0037] In one embodiment, the control panel 16 is equipped with a reminder system and an alarm system to monitor the operation of the device and prevent errors from occurring.

[0038] In one embodiment, such as Figure 1 As shown, both the bottom of the housing 1 and the frame 18 are equipped with support legs for easy movement of the subsequent devices.

[0039] The various technical features in the above embodiments can be combined arbitrarily, as long as there is no conflict or contradiction between the combinations of features. However, due to space limitations, they are not described one by one.

[0040] The above description is only a part of the embodiments of the present invention, and is not intended to limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the content of the present invention specification should be included within the protection scope of the present invention.
