Description

Technical Field

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

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. Hinges are very common furniture door connectors. They use the principle of movable hinges to allow the door to open or close around an axis. In current hinge manufacturing, because they have many connecting parts, which require assembly methods such as riveting, plugging, and snapping, existing hinges are usually assembled using automatic assembly machines.

[0003] When using an automatic assembly machine to assemble door hinges, the use of a vibratory feeder eliminates the inconvenience of manual feeding in the traditional method. The vibratory feeder, through its own resonance and flat vibration, can arrange and transport the hinge parts in an orderly manner. However, the vibratory feeder generates a lot of noise during the vibration process, and coupled with the long processing time, the noise pollution is relatively long-lasting, which can be harmful to the health of workers in the production workshop.

[0004] In addition, during the material feeding process using a vibratory feeder, the lack of a corresponding reminder device means that after the hinge parts inside the vibratory feeder have been transferred, the operator cannot be promptly reminded to replenish the hinge parts. This results in the vibratory feeder performing ineffective transfer work, which further affects the normal processing of other parts of the automatic assembly machine, leading to low assembly efficiency. To address the above issues, we propose an automatic door hinge assembly machine. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the present invention discloses an automatic door hinge assembly machine to solve the problems mentioned in the background art.

A handle is fixedly installed on one side of the first and second soundproof covers. A warning light is mounted on the upper surface of the first soundproof cover.

[0010] The opening and closing mechanism includes a rotating rod, a gear, a first toothed plate, a second toothed plate, and an L-shaped plate. The rotating rod is rotatably connected to the side of the operating table. A gear is fixedly sleeved on the outer surface of one end of the rotating rod extending into the operating table. A connecting groove is formed on the upper surface of the operating table. The first toothed plate and the second toothed plate are slidably connected inside the connecting groove. One end of the first toothed plate is fixedly installed on the lower surface of the second soundproof cover. An L-shaped plate is fixedly installed on one side of the second toothed plate. One end of the L-shaped plate is fixedly installed on the lower surface of the first soundproof cover. Both the first toothed plate and the second toothed plate mesh with the outer surface of the gear.

[0011] Preferably, the outer surface of the rotating rod located outside the operating table has a threaded groove, and a fixing ring is fixedly installed on the side of the operating table, with a threaded groove on the inner surface of the fixing ring.

[0012] Preferably, a threaded block is threadedly fitted onto the outer surface of one end of the rotating rod where a threaded groove is provided, and a counter-rotating ring is fixedly installed on the outer surface of one end of the threaded block. Threaded strips are fitted onto both the inner and outer surfaces of the threaded block, and the outer surface of one end of the threaded block is threadedly inserted into the interior of the fixed ring.

[0013] Preferably, a connecting shell is fixedly installed on the upper surface of the first soundproof cover, the warning light is assembled on one side of the connecting shell, and a hole is opened in the inner top of the first soundproof cover, the hole being connected to the connecting shell.

[0014] Preferably, a controller is fixedly installed inside the connecting shell, a sensor is mounted on the upper surface of the controller, and an alert mechanism is mounted inside the connecting shell.

[0015] Preferably, the reminder mechanism includes a movable plate, a connecting plate, a connecting block, and a movable block. The movable plate is movably hinged inside the hole. Fixed grooves are provided on the inner sidewalls of both the connecting shell and the hole. A connecting block is slidably connected inside the fixed groove. A connecting plate is movably hinged between two sets of connecting blocks. The other end of the connecting plate is movably hinged to the side of the movable plate. A movable block is slidably connected to the upper end of the connecting block. A trigger is fixedly installed at the top of the movable block. The trigger and the sensor move against each other.

[0016] Preferably, a limiting groove is formed on the inner side wall of the fixing groove, and the two sets of connecting blocks are slidably connected inside the limiting groove.

[0017] Preferably, the limiting groove is slidably connected to a limiting block, and the two sets of limiting blocks are respectively fixedly installed on both sides of the moving block, with the two sets of limiting blocks located at the upper end of the connecting block.

[0018] This invention discloses an automatic door hinge assembly machine, which has the following beneficial effects:

[0019] 1. When the automatic assembly machine is in use, by installing a first soundproof cover and a second soundproof cover on the upper surface of the operating table equipped with a vibratory feeder, and installing sound insulation cotton inside the first soundproof cover and the second soundproof cover, the noise generated by the vibratory feeder during operation is isolated inside the first soundproof cover and the second soundproof cover. This can effectively reduce the noise generated during the vibration process of the vibratory feeder for a long time, thereby reducing the harm of noise pollution to the health of workers in the production workshop.

[0020] 2. When using the automatic assembly machine, pull the handle installed on one side of the first or second soundproof cover, and then move the first or second soundproof cover. This causes the toothed plates installed on the lower surface of the first and / or second soundproof covers to move. Under the action of the two sets of toothed plates and the gears meshing between the two sets of toothed plates, the first and second soundproof covers move simultaneously toward the middle or simultaneously to both sides, so that the vibrating discs located inside the two sets of soundproof covers are covered or exposed, thereby controlling the machine to perform noise reduction operation on the vibrating discs.

[0021] 3. When the automatic assembly machine is in use, after the hinge parts inside the vibratory feeder have been transferred, the pushing force on one end of the moving plate disappears, causing the pushing force of the moving plate and connecting plate on the moving block to disappear as well. This allows the moving block and the trigger mounted on its top to slide downwards under their own weight, causing the trigger to come into contact with the sensor. This triggers the controller connected to the warning light to activate the warning light, causing it to flash continuously and emit a sound. This promptly reminds the operator to add hinge parts inside the vibratory feeder, reducing the impact on the production efficiency of the automatic assembly machine. Attached Figure Description

[0032] This invention discloses an automatic door hinge assembly machine, such as... Figure 1-9 As shown, the assembly includes an operating table 1, with a vibratory plate 2 mounted on the upper surface of the operating table 1. A conveying channel 3 is mounted on one side of the vibratory plate 2. The two parts that make up the hinge are placed inside the two sets of vibratory plates 2 respectively. Then, through the resonance and flat vibration of the vibratory plate 2 itself, the hinge parts assembled inside it are conveyed to other processing parts of the assembly machine through the conveying channel 3.

[0033] See attached document Figure 1-2As shown, a first soundproof cover 4 and a second soundproof cover 5 are slidably connected to the upper surface of the operating table 1. The inner surfaces of the first soundproof cover 4 and the second soundproof cover 5 are equipped with sound insulation cotton 7. A connection port 8 is opened on one side of the first soundproof cover 4 and the second soundproof cover 5. Two sets of conveying channels 3 are movably locked inside the connection port 8. Two sets of vibrating plates 2 are located inside the first soundproof cover 4 and the second soundproof cover 5. A handle 6 is fixedly installed on one side of the first soundproof cover 4 and the second soundproof cover 5. A warning light 14 is installed on the upper surface of the first soundproof cover 4. By installing two sets of soundproof covers on the upper surface of the operating table 1 where the vibrating plates 2 are set, the sound insulation cotton 7 installed inside the soundproof cover can isolate the noise generated during the vibration of the vibrating plates 2, thereby reducing noise pollution during the processing.

[0034] See attached document Figure 3-4 As shown, the opening and closing mechanism 10 includes a rotating rod 101, a gear 102, a first gear plate 103, a second gear plate 104, and an L-shaped plate 105. The rotating rod 101 is rotatably connected to the side of the operating table 1. A gear 102 is fixedly sleeved on the outer surface of one end of the rotating rod 101 extending into the operating table 1. A connecting groove 9 is provided on the upper surface of the operating table 1. The first gear plate 103 and the second gear plate 104 are slidably connected inside the connecting groove 9. One end of the first gear plate 103 is fixedly installed on the lower surface of the second soundproof cover 5. An L-shaped plate 105 is fixedly installed on one side of the second gear plate 104. One end of 5 is fixedly installed on the lower surface of the first soundproof cover 4. The first toothed plate 103 and the second toothed plate 104 are both meshed on the outer surface of the gear 102. By pulling the handle 6 installed on one side of the first soundproof cover 4 or the second soundproof cover 5, and then pulling the first soundproof cover 4 or the second soundproof cover 5 to one side, a set of toothed plates is moved. Under the action of the gear 102 meshing with it and another set of toothed plates meshing with the gear 102, the first soundproof cover 4 and the second soundproof cover 5 are moved to both sides or to the middle at the same time, so that the vibrating plate 2 located inside the two sets of soundproof covers is exposed or blocked.

[0035] See attached document Figure 2 , 5As shown, the outer surface of the rotating rod 101 located outside the operating table 1 has a threaded groove. A fixing ring 11 is fixedly installed on the side of the operating table 1. The inner surface of the fixing ring 11 has a threaded groove. A threaded block 12 is threadedly sleeved on the outer surface of the rotating rod 101 located outside the threaded groove. A counter-rotating ring is fixedly installed on the outer surface of one end of the threaded block 12. Threaded strips are fitted on both the inner and outer surfaces of the threaded block 12. The outer surface of one end of the threaded block 12 is threadedly inserted into the inside of the fixing ring 11. The gear 102 is fixedly sleeved on the outer surface of the rotating rod 101. At this time, by rotating the threaded block 12 threadedly sleeved on the outer surface of the rotating rod 101 located outside the operating table 1, the threaded block 12 gradually moves into the inside of the fixing ring 11 fixedly installed on the side of the operating table 1 until the outer surface of the threaded block 12 is threadedly inserted into the inside of the fixing ring 11. This makes the rotating rod 101 and the gear 102 installed on its outer surface in a fixed state, thereby making the first soundproof cover 4 and the second soundproof cover 5 connected to the gear 102 through the gear plate in a fixed state.

[0036] See attached document Figure 6 , 7 As shown, a connecting shell 13 is fixedly installed on the upper surface of the first soundproof cover 4, and a warning light 14 is mounted on one side of the connecting shell 13. A hole is opened in the top inner part of the first soundproof cover 4, and the hole is connected to the connecting shell 13. A controller 16 is fixedly installed inside the connecting shell 13, and a sensor 17 is mounted on the upper surface of the controller 16. A reminder mechanism 15 is mounted inside the connecting shell 13. Through the function of the warning light 14, a reminder operation can be performed after the hinge parts added inside the vibratory feeder 2 have been transferred, so as to prevent the vibratory feeder 2 from continuing to operate after the hinge parts have been transferred.

[0037] See attached document Figure 7-9As shown, the reminder mechanism 15 includes a movable plate 151, a connecting plate 152, a connecting block 153, and a moving block 154. The movable plate 151 is hinged to the inside of the hole. Fixed grooves 20 are provided on both the connecting shell 13 and the inner sidewall of the hole. Connecting blocks 153 are slidably connected inside the fixed grooves 20. Connecting plates 152 are hinged between two sets of connecting blocks 153. The other end of the connecting plate 152 is hinged to the side of the movable plate 151. The moving block 154 is slidably connected to the upper end of the connecting block 153. A trigger 18 is fixedly installed on the top of the moving block 154. The movable plate 151 is made of rubber and is movably inserted into the inside of the conveyor channel 3. When the hinge part moves to the next processing part through the conveyor channel 3, it will first contact the movable plate 151 and push the movable plate 151 to rotate. This will cause the connecting plate 152 hinged to one side of the movable plate 151 to push the moving block 154 inside the connecting shell 13 to move. This will allow control of the connection state between the trigger 18 installed at the top of the moving block 154 and the sensor 17 inside the connecting shell 13, so as to control the state of the warning light 14.

[0038] See attached document Figure 8-9 As shown, a limiting groove 21 is provided on the inner side wall of the fixed groove 20. Two sets of connecting blocks 153 are slidably connected inside the limiting groove 21. A limiting block 19 is slidably connected inside the limiting groove 21. The two sets of limiting blocks 19 are respectively fixedly installed on both sides of the moving block 154. The two sets of limiting blocks 19 are located at the upper end of the connecting block 153. Through the action of the limiting groove 21 and the limiting block 19, the moving block 154 is limited to slide inside the connecting shell 13. Under the action of the limiting groove 21 and the connecting block 153, one end of the connecting plate 152 is always connected to the limiting groove 21.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings and through embodiments.

[0040] Working principle:

[0041] Before the device is used, the first soundproof cover 4 or the second soundproof cover 5 is located at both ends of the upper surface of the operating table 1, and the two sets of vibrating plates 2 inside the first soundproof cover 4 or the second soundproof cover 5 are exposed. At this time, the two parts that make up the hinge can be placed inside the two sets of vibrating plates 2 respectively.

[0042] Furthermore, after the hinge parts are added to the inside of the vibratory plate 2, the threaded block 12, which is threaded on the outer surface of the rotating rod 101 located outside the operating table 1, can be rotated first. This causes the threaded block 12 to gradually move towards the outside of the fixing ring 11 fixedly installed on the side of the operating table 1, so that the threads on the outer surface of the threaded block 12 separate from the fixing ring 11. This makes the rotating rod 101 and the gear 102 installed on its outer surface in an active state, thereby making the first soundproof cover 4 or the second soundproof cover 5, which is connected to the gear 102 through the tooth plate, in an active state.

[0043] Furthermore, pull the handle 6 installed on one side of the first soundproof cover 4 or the second soundproof cover 5, and then push the first soundproof cover 4 or the second soundproof cover 5 towards the middle, so that the toothed plates installed on the lower surface of the first soundproof cover 4 and / or the second soundproof cover 5 move. Under the action of the two sets of toothed plates and the gears 102 meshing between the two sets of toothed plates, the first soundproof cover 4 and the second soundproof cover 5 move towards the middle at the same time, so that the vibrating plate 2 located inside the two sets of soundproof covers is blocked. At this time, the transmission channel 3 installed on one side of the vibrating plate 2 is engaged with the connection port 8 opened on the side of the first soundproof cover 4 or the second soundproof cover 5.

[0044] Furthermore, by rotating the threaded block 12, which is threaded onto the outer surface of the rotating rod 101 located outside the operating table 1, the threaded block 12 gradually moves into the inside of the fixing ring 11 fixedly installed on the side of the operating table 1, until the outer surface of the threaded block 12 is threaded into the inside of the fixing ring 11. This makes the rotating rod 101 and the gear 102 installed on its outer surface in a fixed state, thereby making the first soundproof cover 4 and the second soundproof cover 5, which are connected to the gear 102 through the gear plate, in a fixed state.

[0045] In addition, when the first soundproof cover 4 and the second soundproof cover 5 isolate the two sets of vibrating discs 2 inside, one end of the movable plate 151 installed at the top of the first soundproof cover 4 is inserted into the inside of the conveying channel 3. At this time, when the reminder mechanism 15 is in the initial state, the trigger 18 installed at the top of the moving block 154 abuts against the sensor 17 installed inside the connecting shell 13, so that the reminder mechanism 15 is triggered, and the warning light 14 installed on one side of the connecting shell 13 is turned on.

[0046] Furthermore, the switch of the vibratory feeder 2 is turned on, so that the two sets of vibratory feeders 2 can operate. At this time, through the resonance and flat vibration of the vibratory feeder 2 itself, the hinge parts assembled inside are transported to other processing parts of the assembly machine through the conveyor channel 3. At this time, the first soundproof cover 4, the second soundproof cover 5 and the soundproof cotton 7 installed inside them can reduce the noise during the vibration of the vibratory feeder 2.

[0047] Furthermore, when the hinge component moves to the next processing section through the conveyor channel 3, the hinge component first contacts the movable plate 151, which is inserted into the conveyor channel 3 at one end, and pushes the bottom end of the movable plate 151 to rotate. This causes the movable plate 151 to push the connecting plate 152, which is hinged to one side, to move. At this time, the end of the connecting plate 152 with the connecting block 153 installed slides upward along the fixed groove 20 under the action of the thrust, so that the end of the connecting plate 152 abuts against the lower surface of the moving block 154, which is slidably connected inside the fixed groove 20. Then, the moving block 154 and the trigger 18 installed at its top can be pushed upward to slide, so that the trigger 18 installed at the top of the moving block 154 separates from the sensor 17 inside the connecting shell 13, so that the warning light 14 is in the off state, thereby prompting the staff that the hinge component is being transmitted stably.

[0048] Furthermore, after the hinge parts inside the vibratory feeder 2 have been transferred, the pushing force on one end of the movable plate 151 disappears, causing the pushing force of the movable plate 151 and the connecting plate 152 on the moving block 154 to disappear. This causes the moving block 154 and the trigger 18 installed on its top to slide downwards under its own gravity, thereby causing the trigger 18 to abut against the sensor 17. This causes the controller 16 connected to the warning light 14 to activate the warning light 14, causing the warning light 14 to flash continuously and emit a sound. This can promptly remind the staff to add hinge parts inside the vibratory feeder 2, reducing the impact on the production efficiency of the automatic assembly machine.

[0049] Finally, after completing the assembly, the control switch of the vibratory feeder 2 can be turned off, so that the device is in the off state, and the external control switch of the warning light 14 can be turned off, so that the vibratory feeder 2 can be in the off state in the initial state when it stops running.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
