[0002] In the traditional hinge installation process, users usually need to hold the hinge with one hand and the screw with the other hand for installation and fixation, which is inefficient, time-consuming and laborious. Moreover, it is particularly inconvenient in narrow spaces or when installing at a high position, and it is easy to cause insecure installation or operation errors. To solve the above drawbacks, the Chinese patent with the application number CN202222961154.X, which is a patent for a rear screw quick-installation bracket of a sliding hinge, discloses that the manufacturer pre-installs the rear bracket during hinge production and presets screws on the rear bracket. When the user installs the hinge, they only need to align the hinge with the installation hole position to easily perform the installation connection, simplifying the installation steps and improving the installation efficiency.

[0003] However, new problems have emerged. The installation of the rear bracket in the prior art still relies on manual operation, and workers need to manually install the rear bracket onto the hinge. Due to manual connection and installation, assembly errors are likely to occur in mass production, resulting in unstable product quality, affecting the assembly quality of the hinge, increasing the maintenance frequency and calibration cost of the hinge to a certain extent, and the production efficiency is difficult to meet the requirements of modern industrial automation and large-scale production.

[0041] The following further specifically describes the present utility model with reference to the accompanying drawings. A rear bracket installation mechanism for an automatic hinge production line includes a turntable assembly 10 and a plurality of fixture assemblies annularly and arrayedly distributed thereon. The hinge 1 to be processed is clamped in the fixture assembly. A vibrating disk assembly 11 is arranged on one side of the turntable assembly 10. The rear bracket 12 is placed in the vibrating disk assembly 11 and is transmitted to the loading mechanism by a conveying rail 13. The turntable assembly 10 rotates to drive the hinge 1 to be processed into the working range of the loading mechanism for the rear bracket 12 loading process;

[0042] The feeding mechanism includes a feeding device 3 and a guiding device 2. A frame 16 is installed on one side of the turntable assembly 10. The feeding device 3 can move horizontally and longitudinally relative to the frame 16.

[0043] The guiding device 2 is connected to the end of the conveying rail 13 to guide and limit the rear bracket 12 transmitted into its working range. The rear bracket 12 enters the working range of the feeding device 3 driven by the conveying rail 13. The feeding device 3 transfers the rear bracket 12 to the fixture assembly, and the fixture assembly pushes the rear bracket 12 to be assembled into the hinge 1 to be processed.

[0044] The hinge to be processed is clamped and fixed in the fixture assembly and is sequentially conveyed by the turntable assembly into the working range of the feeding mechanism. At this time, the rear bracket built in the vibrating disk assembly enters the working range of the feeding mechanism through the vibration orientation of the vibrating disk and the conveying of the conveying rail, waiting for the guiding separation and feeding operation of the feeding mechanism. Immediately afterwards, after the feeding mechanism and the fixture assembly cooperate to complete the installation process of the rear bracket, the turntable assembly continues to rotate, and the next hinge to be processed enters the feeding station, repeating the above operations such as guiding, limiting, grasping, and installing. The whole process is automatically intelligent, significantly reducing manual operations and improving the feeding production efficiency of the rear bracket. At the same time, the process functions of the turntable assembly, vibrating disk assembly, feeding mechanism, fixture assembly, etc. are modularized, optimizing the production rhythm, suitable for large-scale mass production, and facilitating the design, manufacture, and maintenance of this automated production line.

[0045] Among them, the feeding mechanism includes a guiding device and a feeding device. The guiding device positions and clamps the rear bracket. At the same time, the feeding device can move in the horizontal and vertical directions relative to the frame to complete the grasping and feeding processes of the rear bracket.

[0046] The top of the conveying rail 13 is recessed downward to form a conveying groove 14. The end of the conveying groove 14 extends and is provided with a deformation groove 141 that expands outward in a shape of an eight-character. One end of the deformation groove 141 away from the conveying groove 14 is connected to a limiting platform 15.

[0047] The setting of the conveying groove further defines the role of the conveying rail in transmission, guiding the rear bracket to move along a fixed path. At the same time, the deformation groove is designed at the end of the conveying groove and expands outward in a shape of an eight-character. When the rear bracket passes through this deformation groove, the deformation groove provides sufficient deformation space for the grasping of the feeding device.

[0048] The guiding device 2 includes a first clamp seat 21 and a second clamp seat 22 that move relative to each other. The two clamp seats are distributed oppositely, and a guiding groove 24 is formed at an interval at the top. The rear bracket 12 is clamped in the guiding groove 24. The guiding groove 24 is located above the deformation groove 141.

[0049] The guide device 2 further includes a guide clamping cylinder 23 , which is connected to the first clamping seat 21 and the second clamping seat 22 . The guide clamping cylinder 23 drives the first clamping seat 21 and the second clamping seat 22 to move relative to each other, thereby adjusting the width of the guide groove 24 .

[0050] The guiding device includes a first clamping seat and a second clamping seat that move relative to each other. The tops of the two clamping seats are spaced apart to form a guiding groove. The top of the rear bracket that enters the deformation groove is restricted, and the rear bracket can only move in the guiding groove, thereby achieving the guidance and limitation of the rear bracket. The vibration plate assembly continuously vibrates the rear bracket, and the rear bracket is continuously transmitted to the conveying rail. The rear bracket at the rear continuously pushes the rear bracket in the front, forcing the rear bracket restricted in the guide groove to continue moving forward until it is stuck on the limit table of the conveying groove. At this time, the rear bracket stops moving and waits to be grabbed by the feeding device. The design of the guide groove ensures that the grabbing position and direction of the rear bracket are correct, provides preparation for the subsequent feeding device, reduces position errors, and accurately positions.

[0051] The width of the guide groove can be adjusted by driving the first clamping seat and the second clamping seat to move relative to each other through the guide clamping cylinder. When the rear bracket needs to be extracted, the guide groove is opened. After the rear bracket is extracted, the guide groove is reset to continue to provide guidance and limit for the next rear bracket.

[0052] The feeding device 3 includes an insert rod 31 and a material ejection barrel 32 sleeved on the outer cylindrical surface of the insert rod. The cylindrical surface of the insert rod 31 is penetrated by an elastic groove 311 . The rear bracket 12 is sleeved outside the cylindrical surface of the insert rod 31 and is located below the material ejection barrel 32 .

[0053] When the rear bracket enters the working range of the feeding device, the insertion rod moves downward under the drive of the longitudinal moving mechanism and is plugged into the shaft hole of the rear bracket. The insertion rod slightly supports the rear bracket. At this time, the deformation groove provides enough space for the deformation of the external support, avoiding the situation where the rear bracket is clamped due to the conventional straight groove. In order to strengthen the connection between the insertion rod and the rear bracket, an elastic groove is provided on the cylindrical surface of the insertion rod. The insertion rod has a certain elasticity. When the rear bracket is inserted into the outer cylindrical surface of the insertion rod, the elastic groove can assist the insertion rod to firmly clamp the rear bracket, enhance the clamping force of the insertion rod, and ensure the stability of the rear bracket during the subsequent movement and assembly process. The ejection barrel is sleeved outside the insertion rod. When the feeding device moves to the top of the hinge to be processed, the ejection barrel pushes out the rear bracket.

[0054] The feeding device 3 also includes a driving platform 34 installed on the outer cylindrical surface of the material withdrawal barrel 32, and the material withdrawal cylinder 33 is connected to one side of the driving platform 34. The material withdrawal cylinder 33 pushes the material withdrawal barrel 32 to extend downward through the driving platform 34, forcing the rear bracket 12 at the bottom of the material withdrawal barrel 32 to separate from the insertion rod 31 and fall into the fixture assembly;

[0055] A pressure plate 35 is installed on the side wall of the driving platform 34, and the rear bracket 12 bears under the pressure plate 35.

[0056] A driving platform is installed and connected to the outer cylindrical surface of the material ejection cylinder, and the driving platform is driven by a material ejection cylinder. When the feeding device moves above the hinge to be processed, the material ejection cylinder pushes the material ejection cylinder to move downward along the insertion rod. The rear bracket bearing on the bottom of the material ejection cylinder is pushed out and detached from the insertion rod under the downward thrust of the material ejection cylinder, and falls into the fixture assembly. In order to further improve the material ejection efficiency, a pressure plate is also installed on the side wall of the driving platform. The rear bracket also bears under the pressure plate. When the material ejection cylinder moves downward, it synchronously drives the pressure plate to move downward, and simultaneously applies a downward pressure to the rear bracket to assist the rear bracket to smoothly detach from the insertion rod. The material ejection cylinder and the pressure plate cooperate to ensure that the rear bracket can accurately detach from the insertion rod and fall into the fixture assembly, improve the assembly efficiency, and realize the automatic and intelligent material ejection operation.

[0057] A guiding platform 36 is sleeved outside the material ejection cylinder 32. A vertically extending guiding hole 361 is provided through the guiding platform 36. The material ejection cylinder 32 is inserted and connected in the guiding hole 361, and the material ejection cylinder 33 pushes the material ejection cylinder 32 to slide axially up and down along the guiding hole 361.

[0058] A guiding platform is provided outside the material ejection cylinder to limit the movement trajectory of the material ejection cylinder, ensuring that the material ejection cylinder can only slide along a specific movement path, ensuring the stability of the movement direction of the material ejection cylinder, avoiding the deviation of the material ejection cylinder during the movement process, improving the positioning accuracy of the rear bracket, and enhancing the assembly accuracy of the hinge.

[0059] A transverse movement mechanism 4 and a longitudinal movement mechanism 5 are installed between the feeding device 3 and the frame 16; the transverse movement mechanism 4 includes a transverse slider 41 fixedly connected above the frame 16 and a transverse slide rail 42 assembled with it. The transverse driving cylinder 43 drives the transverse slide rail 42 to slide along the transverse slider 41 to realize the movement of the feeding device 3 in the transverse direction;

[0060] The transverse movement mechanism 4 further includes a transverse connecting plate 44 located in front of the transverse slide rail 42, and the longitudinal movement mechanism 5 is installed on the transverse connecting plate 44.

[0061] A transverse movement mechanism is provided between the feeding device and the frame. Using the simple sliding structure of the transverse slide rail and the transverse slider, it ensures a stable and reliable sliding process, significantly reducing the influence brought by the vibration during the movement process. The transverse driving cylinder provides efficient driving force to quickly adjust the transverse position of the feeding device, improving the production efficiency, realizing high-precision and repetitive transverse positioning, and meeting the accuracy requirements of the automated production line.

[0062] The longitudinal movement mechanism 5 includes a longitudinal slider 51 installed in front of the transverse connecting plate 44 and a longitudinal slide rail 52 assembled therewith. The longitudinal driving cylinder 53 drives the longitudinal slide rail 52 to slide along the longitudinal slider 51, realizing the movement of the feeding device 3 in the longitudinal direction;

[0063] The longitudinal movement mechanism 5 further includes a longitudinal connecting plate 54 located in front of the longitudinal slide rail 52, and the feeding device 3 is installed on the longitudinal connecting plate 54.

[0064] A longitudinal movement mechanism is also provided between the feeding device and the frame. By using the simple sliding structure of the longitudinal slide rail and the longitudinal slider, the sliding process is ensured to be stable and reliable, significantly reducing the influence brought by the vibration during the movement process. The longitudinal driving cylinder provides efficient driving force to quickly adjust the longitudinal position of the feeding device, improving production efficiency, achieving high-precision and repetitive longitudinal positioning, and meeting the accuracy requirements of the automated production line.

[0065] The fixture assembly includes a fixture 6 and its driving device 7. One side of the fixture 6 is slidably connected with a guide seat 61, and the rear bracket 12 falls into the guide seat 61;

[0066] The fixture assembly further includes a push rod 62 inserted across the bottom of the guide seat 61. A chute 63 extending along the length direction of the hinge 1 to be processed is provided through the fixture 6, and the push rod 62 is inserted and connected in the chute 63; A spring 65 is arranged between the push rod 62 and the fixture 6. The bottom of the push rod 62 extends out and is connected with a spring column 67. The fixture 6 is provided with a spring hole 66. One end of the spring 65 extends and is installed in the spring hole 66, and the other end of the spring 65 is hooked on the spring column 67;

[0067] Rollers 64 are rotatably installed at both ends of the push rod 62 in a protruding manner, and the driving device 7 is in contact with the rollers 64.

[0068] The feeding device installs the rear bracket into the guide seat of the fixture assembly. At this time, the driving device descends and the driving device is away from the push rod. Since a spring is arranged between the push rod and the fixture, the fixed end of the spring extends into the spring hole provided in the fixture for fixation, and the free end of the spring is hooked on the spring column at the bottom of the push rod. The spring always generates a pulling force on the push rod in the direction of the hinge to be processed. After the push rod loses the driving force of the driving device, the pulling force of the spring pulls the push rod and the guide seat forward in the direction of the hinge to be processed, driving the rear bracket located on the guide seat to move forward synchronously, so that the elastic buckle at the front end of the rear bracket is buckled onto the pin shaft at the tail of the hinge to be processed, realizing the assembly of the rear bracket and the hinge to be processed. Among them, in order to improve the assembly accuracy requirements, a chute extending along the length direction of the hinge to be processed is provided through the fixture, and the push rod is inserted into the chute to guide and limit the movement of the push rod.

[0069] The driving device 7 includes a driving cylinder 71 and a pushing platform 72 connected to the top thereof. The top of the pushing platform 72 is inclined to form a driving inclined surface. The roller 64 is pressed on the driving inclined surface. The driving cylinder 71 drives the pushing platform 72 to lift, driving the pushing rod 62 to slide away from the end of the hinge 1 to be processed along the chute 63, and the guide base 61 resets, waiting for the feeding device 3 to feed the rear bracket 12.

[0070] The pushing platform is arranged with an inclined top to form a driving inclined surface. The rollers at both ends of the pushing rod are press-connected to the driving inclined surface. When the driving cylinder drives the pushing platform to rise, the rollers slide along the driving inclined surface, converting the axial movement of the pushing platform into the lateral movement of the pushing rod, causing the pushing rod to slide away from the hinge to be processed, driving the guide base to reset, and waiting for the feeding device to perform the feeding operation of the next rear bracket. When the driving cylinder drives the pushing platform to descend, the pushing rod is separated from contact with the pushing platform. At this time, under the pulling force of the above spring, the pushing rod drives the rear bracket to be assembled with the hinge to be processed.

[0071] In summary, in this case, the hinge to be processed is fixed on the turntable assembly through the fixture assembly. The turntable assembly rotates, and the hinge to be processed is successively fed into the working range of the feeding mechanism for the rear bracket assembly operation. At the same time, after the rear brackets are sorted by the vibrating disk assembly, they are sent to the feeding device and the guiding device through the conveying rail. The guiding device guides and positions the rear brackets, and the feeding device extracts the rear brackets within its working range and transfers them to the fixture assembly. The fixture assembly feeds and assembles the rear brackets that fall into it. During the entire feeding process of the rear brackets, no manual intervention is required, eliminating the cumbersome steps of traditional manual assembly, improving the production speed and efficiency. The continuous design of the turntable assembly further ensures the seamless connection of the processing process and optimizes the overall process of the production line.

[0072] Through the fully automatic processes of conveying, grasping, positioning and guiding, and installation, the manual intervention is minimized, thereby reducing the assembly inconsistency or quality problems caused by human operation errors, and further improving the reliability and consistency of production.

[0073] At the same time, a deformation groove is provided at the end of the above-mentioned conveying rail. The cooperation between the deformation groove and the limiting platform initially grabs and positions the rear bracket and provides space for the deformation during later grabbing. The guiding groove formed by the guiding device guides and positions the rear bracket entering the deformation groove to ensure that the inserting rod can accurately insert into the rear bracket, ensuring that the rear bracket is in the correct position before insertion, improving the assembly accuracy, reducing the assembly error, and enhancing the stability of the product quality. The guiding groove is designed as an adjustable structure to adapt to the assembly of rear brackets and hinges of various different specifications and sizes, enhancing the application potential of the production line and having high versatility.

[0074] Furthermore, as the main material discharging component, the material discharging cylinder of the feeding device is provided with a pressure plate as an auxiliary material discharging component. The two cooperate with each other to ensure that the rear bracket can smoothly disengage from the insertion rod, ensuring the stability and reliability of the feeding process, reducing assembly defects caused by incomplete disengagement, and ensuring the stability of the production line operation. Therefore, it can be widely promoted.

[0075] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
