Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly of hardware hinges, in particular to an eccentric wheel automatic feeder for a hinge automatic production line. Background Art

[0002] With the continuous improvement of market requirements for product functions and quality, hinges, as a basic mechanical component, are widely used in equipment fields such as doors and windows to realize the relative rotational movement between two components. In a traditional hinge production line, there is often a turntable for rotating the processed hinge and a jig for clamping and fixing the processed hinge. The processed hinge is sequentially fed into different processing stations by the rotation of the turntable to complete assembly processes including eccentric wheel feeding and hinge assembly. The function of the eccentric wheel is to adjust the position or tension of the hinge to meet the requirements of different usage environments. In the automated production lines of the prior art, a robotic arm is often used for the feeding operation to pick up and install the eccentric wheel. During the automatic feeding process, the eccentric wheels need to be separated one by one from the batch supply and accurately aligned for installation. Traditional separation devices rely on separators or optical sensors, and these methods are prone to misoperations during high-speed operation, resulting in easy detachment during the separation process of the eccentric wheels, or inaccurate installation positioning of the separated eccentric wheels, thus causing jamming or incorrect installation of the eccentric wheels, affecting the assembly quality of the hinges, increasing the maintenance frequency and calibration cost of the equipment. Therefore, it is necessary to make further improvements to it. Summary of the Utility Model

[0004] The purpose of the utility model is achieved in the following way: An eccentric wheel automatic feeder for a hinge automatic production line includes a turntable assembly and a plurality of jig assemblies annularly and arrayedly distributed above it. The hinge to be processed is clamped in the jig assembly. A vibrating disc assembly is arranged on one side of the turntable assembly.

The bottoms of the first clamping seat and the second clamping seat are concave to form clamping grooves. The clamping cylinders drive the first clamping seat and the second clamping seat to move relative to each other, clamping the eccentric wheel to be loaded in the clamping grooves.

[0012] Fixing plates are arranged outside the first clamping seat and the second clamping seat. A positioning seat protrudes from one side of the fixing plate. The positioning seat extends into the space between the first clamping seat and the second clamping seat and is connected to a top rod placed between two sliding seats. The eccentric wheel to be loaded is pressed below the top rod. The bottom of the clamping cylinder is connected to a sliding groove, and the sliding seats are slidably clamped in the sliding groove.

The guiding groove is a waist-shaped groove extending axially.

[0014] A spring is sleeved outside the ejector rod. One end of the spring abuts against the lower part of the movable cavity, and the other end abuts against the ejector rod. The spring generates a thrust force to push the ejector rod downward, forcing the eccentric wheel to be connected to the ejector rod to press downward.

[0035] The following further specifically describes the present invention with reference to the drawings. An eccentric wheel automatic feeder for a hinge automatic production line includes a turntable assembly 11 and a plurality of fixture assemblies 13 annularly and arrayedly distributed above it. The hinge 1 to be processed is clamped in the fixture assembly 13. A vibrating bowl assembly 12 is arranged on one side of the turntable assembly 11. The eccentric wheel 10 is built in the vibrating bowl assembly 12 and is transported to the feeding mechanism by the conveying rail 14. The turntable assembly rotates to drive the hinge 1 to be processed into the working range of the feeding mechanism for the eccentric wheel 10 feeding process.

[0036] The feeding mechanism includes a feeding device and a separating device. A frame 15 is installed on one side of the turntable assembly 11. The feeding device is connected to the frame 15 through a longitudinal moving mechanism 6 and a transverse moving mechanism 5. The transverse moving mechanism 5 drives the feeding device to move horizontally, and the longitudinal moving mechanism 6 drives the feeding device to move vertically, realizing the movement of the feeding device in the horizontal and vertical directions.

[0037] The separating device includes a separating bit 4 axially connected to the eccentric wheel 10. An axial cylinder 41 and a transverse cylinder 42 are installed below the separating bit 4. The axial cylinder 41 drives the separating bit 4 to rise and be axially connected to the eccentric wheel 10, and the transverse cylinder 42 drives the separating bit 4 to disengage from the conveying rail 14 and enter the working range of the feeding device.

[0038] The feeding device includes a first driving arm and a second driving arm that move synchronously. A rotating device 3 is installed at the top of the first driving arm, and the rotating device 3 drives the first driving arm to rotate. The feeding device takes out the eccentric wheel 10 from the separating device and installs it into the hinge 1 to be processed.

[0039] As Figure 2-3 shown, the hinge to be processed is clamped and fixed in the fixture assembly and is sequentially rotated and conveyed by the turntable assembly to the working range of the feeding mechanism. At this time, the eccentric wheel built in the vibrating disk assembly has been positioned and placed in the working range of the feeding mechanism through the vibration orientation of the vibrating disk and the transmission of the conveying rail, waiting for the separation and feeding operations of the feeding mechanism. After the feeding mechanism completes the feeding process, the turntable assembly continues to rotate, and the next hinge to be processed enters the feeding station, repeating the above processes of separation, grasping, positioning, installation, etc. automatically and intelligently, significantly reducing manual operations and improving the feeding production efficiency of the eccentric wheel. At the same time, the process functions of the turntable assembly, vibrating disk assembly, feeding mechanism, etc. are modularized, facilitating the design, manufacturing, and maintenance of this automated production line.

[0040] Among them, when the eccentric wheel reaches the end of the conveying rail, the separating device starts to work at this time. The axial cylinder drives the separating bit to rise and be axially connected to the eccentric wheel to separate the eccentric wheel. At this time, the transverse cylinder drives the separating bit to move horizontally, so that the separated eccentric wheel disengages from the conveying rail and enters the working range of the feeding device, ensuring that the eccentric wheel is always stably fixed during the separation and transmission processes, avoiding falling off, and improving the continuity and safety of the feeding operation.

[0041] Immediately afterwards, the feeding device starts. A rotating device is installed at the top of the first driving arm. The first driving arm first extracts the separated eccentric wheel, rotates the eccentric wheel in a certain direction through the rotating device, rotates the eccentric wheel to the required installation angle, and transports it to the hinge to be processed for installation. The second driving arm and the first driving arm perform relative movements and cooperate with each other to grab the eccentric wheel from the separating bit head, providing a certain production basis for subsequent more complex coordinated cooperation or assembly line operations.

[0042] Furthermore, at the feeding device end, it is connected to the machine frame through a longitudinal moving mechanism and a transverse moving mechanism. The transverse moving mechanism drives the feeding device to move in the transverse direction, and the longitudinal moving mechanism drives the feeding device to move in the longitudinal direction. The two perform movements in the transverse and longitudinal directions of the entire feeding device, and the eccentric wheel can ensure accurate positioning above the hinge to be processed, meeting the installation production requirements of different workstations and hinges.

[0043] The separating device further includes a transfer seat 43 located in front of the separating bit head 4. The first driving arm extracts the eccentric wheel 10 to be loaded from the separating bit head 4 and transports it into the transfer seat 43, waiting for the second driving arm to extract it.

[0044] As Figure 8 shown, a transfer seat is designed in the separating device. After the first driving arm extracts the eccentric wheel from the separating bit head, the first driving arm moves into the transfer seat and places the eccentric wheel. At this time, the second driving arm extracts the eccentric wheel from the transfer seat and then moves it to the hinge to be processed for loading operation. The introduction of the transfer seat component enables partial synchronous operation of the loading operations of the first driving arm and the second driving arm. When the second driving arm performs the installation movement, the first driving arm can extract the eccentric wheel from the separating bit head in advance and place it in the transfer seat. The two driving arms are decoupled and combined through the transfer seat, and the movement control of the two driving arms is more independent, shortening the overall production loading cycle time and improving production efficiency.

[0045] The separating device further includes a fixed frame 44 distributed in front of the machine frame 15. A transverse driving plate 45 is inserted and installed in the fixed frame 44. The transverse driving plate 45 is connected to a transverse air cylinder 42. The transverse air cylinder 42 drives the transverse driving plate 45 to slide horizontally in the fixed frame 44, driving the separating bit head 4 to perform a transverse movement.

[0046] As Figure 8As shown, one end of the transverse cylinder is connected to the transverse drive plate. A fixed frame is installed in front of the frame, and the transverse drive plate is slidably inserted in the fixed frame. The fixed frame serves as a guide rail for the transverse drive plate. The transverse cylinder drives the transverse drive plate to move in the transverse direction along the fixed frame, providing a stable and precise guide for the transverse movement of the separation head, ensuring the stability of the transverse movement of the separation head and the precise positioning. The two cooperate with each other to improve the carrying capacity of the separation head. At the same time, the transverse cylinder directly acts on the transverse drive plate, and the transmission chain and movement path are clear and simple, which is convenient for the control and maintenance of the separation head.

[0047] The separation device further comprises a mounting tube 46 sleeved on the outside of the separation bit 4, the outer ring of the mounting tube 46 is connected with an axial guide plate 47, and the axial guide plate 47 is connected to the transverse drive plate 45 through an axial connecting plate 48;

[0048] The separating bit 4 is connected to the axial cylinder 41 via the mounting tube 46 , and the axial cylinder 41 drives the separating bit 4 to move in the axial direction.

[0049] like Figure 8 As shown, the axial cylinder is connected to the separation bit through the mounting tube, and the axial cylinder operates to achieve axial docking and separation of the eccentric wheel. An axial guide plate is connected to the outer ring of the mounting tube. The axial guide plate serves as a guide component of the mounting tube. The axial cylinder drives the mounting tube to move axially along the axial guide plate, providing a stable and precise guide for the axial movement of the separation bit, ensuring the stability of the axial movement and precise positioning of the separation bit. The cooperation between the two can also improve the carrying capacity of the separation bit. At the same time, the transverse cylinder directly acts on the transverse drive plate, and the transmission chain and movement path are clear and simple, which is convenient for the control and maintenance of the separation bit.

[0050] The first driving arm and the second driving arm both include a clamping cylinder 21, and the clamping cylinder 21 is connected to a first clamping seat 22 and a second clamping seat 23. The bottoms of the first clamping seat 22 and the second clamping seat 23 are concave to form a clamping groove 24. The clamping cylinder 21 drives the first clamping seat 22 and the second clamping seat 23 to move relative to each other, and clamps the eccentric wheel 10 to be loaded in the clamping groove 24.

[0051] like Figure 7 As shown, the first driving arm and the second driving arm both include a clamping cylinder, and the first clamping seat and the second clamping seat are connected and installed at the ends of the clamping cylinder as the gripping parts for the eccentric wheel. When the clamping cylinder is in operation, the first clamping seat and the second clamping seat are driven to move relative to each other, and the eccentric wheel is clamped and placed in the clamping groove formed by the two. By the ventilation or air-off operation of the clamping cylinder, the first clamping seat and the second clamping seat are driven to move relatively close to or separate from each other, so as to realize the gripping or release of the eccentric wheel.

[0052] A fixing plate 25 is disposed outside the first clamping seat 22 and the second clamping seat 23. A positioning seat 26 protrudes from one side of the fixing plate 25. The positioning seat 26 extends into the space between the first clamping seat 22 and the second clamping seat 23 and is connected to a push rod 28 disposed between two sliding seats 27. The eccentric wheel 10 to be loaded is pressed below the push rod 28. The bottom of the clamping cylinder 21 is connected to a sliding groove 29, and the sliding seats 27 are slidably clamped in the sliding groove 29.

[0053] An activity cavity 262 is disposed through the positioning seat 26, and the push rod 28 is slidably inserted into the activity cavity 262. A sliding rod is connected across the activity cavity 262. The sliding rod sequentially passes through a guiding groove 261 of the positioning seat 26 and is connected to a mounting hole 281 of the push rod 28. The guiding groove 261 is a waist-shaped groove extending axially.

[0054] A spring 8 is sleeved outside the push rod 28. One end of the spring 8 abuts against the lower part of the activity cavity 262, and the other end abuts against the push rod 28. The spring 8 generates a thrust force to push the push rod 28 to extend downward, forcing the eccentric wheel 10 to be loaded and connected to be pressed downward, and the eccentric wheel 10 is always locked in the hinge 1 to be processed.

[0055] As Figure 7 shown, a fixing plate is provided to connect and fix the positioning seat. The positioning seat extends into the middle of the two clamping seats and is connected to the push rod disposed therein, restricting the lateral movement and rotational movement of the push rod, and allowing the push rod to slide axially up and down in the guiding groove of the positioning seat. When the second driving arm moves the eccentric wheel to be loaded above the hinge to be processed and descends for installation, the clamping groove is responsible for clamping and positioning the eccentric wheel, and the spring sleeved outside the push rod applies a continuous downward thrust force to the push rod, pushing the push rod to always extend downward. When the fixture is released, this downward thrust force presses the eccentric wheel into the installation hole position of the hinge and locks it, ensuring that the eccentric wheel is accurately positioned within the clamping seat. The spring provides a flexible pressure to press and lock the eccentric wheel, avoiding the problem that mechanical hard alignment is likely to cause damage to components.

[0056] Furthermore, the sliding seat and its assembled sliding groove are used to slidably connect the clamping seat, enabling the two clamping seats to perform clamping or releasing operations smoothly without hindrance, ensuring the function of the clamping seat. The above-mentioned spring is integrally combined with the clamping seat, with a compact structure and no need to add additional external components. During the entire loading and installation process of the eccentric wheel, the push rod continuously applies pressure to the eccentric wheel until the eccentric wheel is released, ensuring the stability of the eccentric wheel before loading and installation.

[0057] The rotating device 3 is installed on the top of the first driving arm. The rotating device 3 includes a rotating cylinder 31 and a rotating shaft 32 installed on the top of the first driving arm. A driving gear 33 is installed outside the rotating shaft 32.

[0058] The described rotating device 3 further includes a rack 34 meshing with the driving gear 33. The rotating cylinder 31 is connected to one side of the rack 34. The rotating cylinder 31 drives the rack 34 to slide, and drives the rotating shaft 32 to rotate through the driving gear 33, realizing the rotation of the first driving arm.

[0059] As Figure 9 As shown, the rotating device is provided with a rotating cylinder. A rack is connected to one side of the rotating cylinder. At the same time, it also includes a driving gear axially connected to the rotating shaft, and the driving gear is meshed and assembled with the rack. The rotating cylinder drives the rack to perform linear sliding, pushing the rack to slide linearly back and forth. The linear motion of the rack is converted into the rotation of the driving gear, thereby realizing the rotation of the first driving arm. It provides a rotating function for the first driving arm, enabling the first driving arm to perform more complex operations, such as adjusting the installation angle of the eccentric wheel to adapt to the hinge assembly, or converting the angle between the extraction point and the placement point. The structure is simple, the transmission is reliable, it is convenient for users to control and maintain, and the cylinder structure provides sufficient driving force to drive the driving arm and the load to rotate.

[0060] The described lateral moving mechanism 5 includes a lateral sliding rail 51 fixed above the frame 15 and a lateral slider 52 assembled with it. The lateral driving motor 53 drives the lateral slider 52 to slide along the lateral sliding rail 51, realizing the movement of the feeding device in the lateral direction; the longitudinal moving mechanism 6 is connected to the lateral slider 52.

[0061] As Figure 6 As shown, the structure and movement mode of the lateral moving mechanism are defined. The lateral sliding rail is used for movement guiding, and the lateral slider is used for movement operation. The two are in sliding fit, and under the drive of the lateral driving motor, the lateral slider moves laterally along the lateral sliding rail, thereby realizing the movement of the feeding device in the lateral direction.

[0062] The simple sliding structure of the lateral sliding rail and the lateral slider ensures the smooth and reliable sliding process, significantly reducing the influence of the vibration during the movement on the concentricity. The lateral driving motor provides efficient driving force, quickly adjusts the lateral position of the feeding device, improves production efficiency, realizes high-precision and repetitive lateral positioning, and meets the accuracy requirements of the automated production line.

[0063] The described longitudinal moving mechanism 6 includes a longitudinal sliding rail 61 connected to the outside of the lateral slider 52 and a longitudinal slider 62 assembled with it. The longitudinal driving cylinder 63 drives the longitudinal slider 62 to slide along the longitudinal sliding rail 61, realizing the movement of the feeding device in the longitudinal direction; the feeding device is connected to the longitudinal slider 62 through the mounting plate 7.

[0064] As Figure 6As shown, the structure and motion mode of the longitudinal moving mechanism are defined. The longitudinal slide rail is used for motion guiding, and the longitudinal slider is used for motion operation. The two are in sliding fit, and driven by the longitudinal driving cylinder, the longitudinal slider moves longitudinally along the longitudinal slide rail, thereby realizing the motion of the feeding device in the longitudinal direction.

[0065] The simple sliding structure of the longitudinal slide rail and the longitudinal slider ensures a stable and reliable sliding process, significantly reducing the influence of vibration during the motion on the concentricity. The longitudinal driving cylinder provides efficient driving force, quickly adjusts the longitudinal position of the feeding device, improves production efficiency, realizes high-precision and repetitive longitudinal positioning, and meets the accuracy requirements of the automated production line.

[0066] 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 eccentric wheel feeding operation. At the same time, after the eccentric wheels are sorted by the vibrating bowl, they are sent to the separation device through the conveying rail. The separation device uses the axial cylinder to drive the separation chuck to rise, dock with the axis of the eccentric wheel at the end of the conveying rail, and then is driven by the transverse cylinder to horizontally move the separation chuck with the eccentric wheel out of the conveying rail.

[0067] At the same time, the first driving arm of the feeding device moves to the separation device. The first driving arm first removes the eccentric wheel from the separation chuck and places it on the transfer seat, and then the second driving arm takes the material from the transfer seat. The first driving arm can adjust the installation angle or direction of the eccentric wheel by using the rotating device at its top.

[0068] The above-mentioned feeding device is installed on an X-Y two-dimensional motion platform composed of a transverse moving mechanism and a longitudinal moving mechanism. According to the program instruction, the feeding device is driven to accurately move to the directly above of the current hinge to be processed. After positioning, the second driving arm descends, aligns the eccentric wheel with the installation position of the hinge. The second driving arm releases the eccentric wheel. Further, the ejector rod built into the clamp seat exerts a continuous downward pressure on the eccentric wheel under the action of the spring, ensuring that the eccentric wheel is firmly and correctly pressed into the hinge. After the installation and feeding operation is completed, the feeding device retracts and returns to its original position, the turntable assembly rotates, and the next hinge enters the working range of the feeding mechanism, repeating the above feeding steps to realize continuous and automated eccentric wheel feeding operation.

[0069] Through the delicate mechanical structure design and the combination of pneumatic and electric drives, a high degree of automation, high efficiency and high precision in the eccentric wheel feeding process in hinge production are achieved. Feeding, separation, transfer, grasping, two-dimensional positioning, rotation, pressing and installation are clearly divided and work in coordination. The positioning is flexible and accurate, the separation is reliable and stable, significantly improving the production efficiency and assembly quality, reducing the labor cost and labor intensity, and the positioning is flexible and accurate, so it can be widely promoted.

[0070] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
