Description

Technical Field

[0001] This invention relates to the technical field of home hardware manufacturing, specifically to a hinge assembly method and the equipment used therein. Background Technology

[0002] Hinges are widely used opening and closing structures in home furnishing products, such as the connection between cabinet doors and cabinet bodies, and the connection between door bodies and door frames, to meet opening and closing needs.

[0003] Currently, existing hinges on the market have a simple structure, consisting of two blades and a pivot. The sides of the two blades are arranged with concave and convex surfaces and are alternately embedded. The pivot connects the alternately embedded parts of the two blades. However, in actual use, the alternating embedded parts of the two blades are in direct contact, leading to excessive wear on the surface coating. Furthermore, to ensure smooth rotation between the two blades, a very small assembly gap is required. Therefore, ensuring the assembly gap is crucial for the hinge's performance. Currently, there are two methods for assembling these hinges: one is to manually pass the pivot through the two blades and lock them together with a nut or riveting. The assembly gap is entirely determined visually, resulting in inconsistent gap sizes. The other method is to use a mold, where several placement slots are created. The two blades are placed in their corresponding slots before the pivot is inserted. However, because easy removal of the blades is necessary during assembly, a gap remains in the placement slots, causing the blades to wobble after placement and during the pivot insertion process. This also results in inconsistent assembly gap sizes, affecting the hinge's performance. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a hinge assembly method and the equipment used therein. The method involves placing pre-processed blades and nylon sleeves into corresponding placement slots on a mold, inserting a thin film pad between the blades and the nylon sleeve, and finally inserting a rotating shaft. The blades and nylon sleeve are then connected by threaded locking or riveting to complete the assembly operation. Furthermore, the method includes a material feeding assembly, a pad placement assembly, and a limiting assembly to place the blades and pads, respectively. Simultaneously, it achieves automatic placement of the thin film pad and completes the installation of the rotating shaft, meeting the hinge assembly requirements. The method features a simple structure and high assembly efficiency.

[0005] The specific technical solution is as follows: A hinge assembly method is provided for assembling a hinge including two blades, a nylon sleeve, and a pivot. Each of the two blades has a plurality of spaced-apart first and second protrusions on one side, which are alternately fitted together. A nylon sleeve is disposed between the first and second protrusions. The pivot passes through each first protrusion, second protrusion, and nylon sleeve. The method comprises the following steps: Step S1, component processing; The blades are stamped, ground, and powder-coated to obtain finished blades. At the same time, the shaft is machined. In addition, nylon sleeves and film pads are purchased. Step S2, assembly; The finished blade is placed in the corresponding mold slot. At the same time, the nylon sleeve is placed between the first and second protrusions of the finished blade. In addition, while the nylon sleeve is placed between the first and second protrusions, a thin film pad is set at one or both ends of the nylon sleeve. Then, the rotating shaft is passed through each first protrusion, second protrusion, nylon sleeve and thin film pad. Finally, the two ends of the rotating shaft are set to limit the assembly operation. Step S3, take the film pad; Remove the film pad from the hinge assembled in step S2 to obtain the finished hinge; Step S4, pack and store; Label the finished hinges obtained in step S3 and bag and box them.

The end limiting component is mounted on the frame and is symmetrically arranged with the through-rotating shaft about the mold. Furthermore, the end limiting component can move telescopically along the movement direction of the through-rotating shaft. The feeding assembly, the shim feeding assembly, and the limiting assembly all act on the same mold when the rotating frame rotates.

[0008] The device used in the above-mentioned hinge assembly method includes a rotating frame comprising a main drive shaft, a frame body, and a main rotary drive. The main drive shaft is a hollow shaft and is rotatably mounted on a platform. The main rotary drive is disposed on a frame and located below the platform. The lower end of the main drive shaft extends to the lower part of the platform and is poweredly connected to the main rotary drive. The upper end of the main drive shaft extends to the upper part of the platform. The frame body is disposed at the upper end of the main drive shaft and rotates with the main drive shaft. The mold is mounted on the frame body.

[0009] The device used in the above-mentioned hinge assembly method includes a blade feeding section comprising a feeding guide groove, a feeding bracket, a vertical sliding member, a horizontal sliding member, an inclined telescopic actuator, and a suction cup. The feeding guide groove is mounted on the frame, with one end extending to the side of the rotating frame. The feeding bracket is mounted on the frame. The vertical sliding member is mounted on the feeding bracket and moves vertically up and down. The horizontal sliding member is mounted on the vertical sliding member and reciprocates between the feeding guide groove and the mold in one direction within the horizontal plane. The inclined telescopic actuator is mounted on the horizontal sliding member and arranged at an inclined angle to the vertical direction. Simultaneously, the telescopic shaft of the inclined telescopic actuator moves closer to or further away from the mold. The suction cup is mounted on the telescopic shaft of the inclined telescopic actuator.

[0010] The device used in the above-mentioned hinge assembly method includes a feeding bracket for one of the two sets of blade feeding sections, whose lower end passes through the hollow of the drive shaft and is fixedly connected to the frame.

[0011] The above-mentioned hinge assembly method and the equipment used therein, wherein the nylon sleeve feeding part includes a moving part, a guide tube and an opening and closing door. The moving part is installed on the feeding bracket and moves towards or away from the mold in one direction along the horizontal plane. Several guide tubes are installed on the moving part at intervals. Several nylon sleeves are stored in the guide tubes. At the same time, an opening and closing door is provided at the lower end of each guide tube. The opening and closing door opens or closes the lower end of the corresponding guide tube.

[0012] The equipment used in the above-mentioned hinge assembly method includes a gasket assembly comprising a gasket support, a gasket lifting drive, a guide plate, a film rotating frame, a pressure roller, an air nozzle, and an angle adjustment component. The gasket support is mounted on the frame and extends to the top of the mold. The gasket lifting drive is mounted on the gasket support and moves vertically. The guide plate is a strip plate and is mounted vertically on the lifting shaft of the gasket lifting drive. A film rotating frame is mounted at the upper end of the guide plate. The film gasket is rolled up and rotatably mounted on the film rotating frame. The angle adjustment component is located at the lower end of the guide plate. An air nozzle is mounted on the angle adjustment component and blows air vertically downwards. The pressure roller is rotatably mounted on the guide plate and located between the film rotating frame and the air nozzle. The end of the rolled-up film gasket passes through the pressure roller and extends to the air nozzle.

[0013] The device used in the above-mentioned hinge assembly method includes a shim placement assembly that further includes a cutting section. The cutting section has scissors, a telescopic slide, and a scissor telescopic actuator. The telescopic slide is mounted on the frame and located beside the table. The scissor telescopic actuator is mounted on the telescopic slide and arranged towards the guide plate. The scissors are mounted on the telescopic shaft of the scissor telescopic actuator. When the telescopic shaft of the scissor telescopic actuator drives the scissors to move towards the guide plate, the scissors move to the area below the guide plate and above the mold.

[0014] The device used in the above-mentioned hinge assembly method includes a rotating shaft portion comprising a rotating shaft groove, a rotating shaft push head, and a rotating shaft push driver. The rotating shaft groove is arranged along the direction in which the first and second protrusions on the blade are alternately embedded and is located on one side of the mold. The rotating shaft push driver is disposed on the side of the rotating shaft groove away from the mold. The rotating shaft push head is slidably disposed in the rotating shaft groove and connected to the push shaft of the rotating shaft push driver. The end limiting portion includes a nut sleeve, a nut rotation driver, and a nut push driver. The nut push driver is disposed on the side of the mold away from the rotating shaft groove. The nut rotation driver is disposed on the push shaft of the nut push driver. A nut sleeve is disposed on the drive shaft of the nut rotation driver. The nut sleeve has a receiving cavity for accommodating a nut that is threadedly connected to the end of the rotating shaft.

[0015] The device used in the above-mentioned hinge assembly method further includes a shim removal assembly. The shim removal assembly is disposed on the frame and located next to another mold of the rotating frame. The shim removal assembly includes a horizontal sliding frame, a vertical telescopic actuator, and a gripper. The horizontal sliding frame is placed horizontally above the rotating frame and moves towards or away from the mold in a horizontal direction. The vertical telescopic actuator is disposed on the horizontal sliding frame, and a gripper is installed on the telescopic shaft of the vertical telescopic actuator.

[0016] The positive effects of the above technical solution are: The aforementioned hinge assembly method and the equipment used involve placing pre-processed blades and nylon sleeves into corresponding slots on a mold, inserting a thin film pad between the blades and the nylon sleeve, and finally inserting a rotating shaft. The blades and nylon sleeve are then connected by a threaded lock using the rotating shaft and nut, thus assembling the hinge. Furthermore, the assembly process utilizes equipment including a feeding assembly, a pad feeding assembly, and a limiting assembly to place the blades and pads, install the nylon sleeve and thin film pad, and lock them in place using the rotating shaft and nut. This method meets the hinge assembly requirements, and the equipment has a simple structure, high assembly efficiency, and is beneficial for hinge production. Attached Figure Description

[0019] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 7 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0020] Figure 1 This is a structural diagram of a hinge according to the present invention. Figure 1 As shown, the hinge to be assembled in this embodiment includes two blades 11, a nylon sleeve 12, and a pivot 13. Each of the two blades 11 has several spaced-apart first protrusions 111 and second protrusions 112 on one side. When the sides of the two blades 11 are hinged, the first protrusions 111 and second protrusions 112 are alternately embedded, ensuring uniform force distribution on the blades 11 and stability after installation. Simultaneously, a nylon sleeve 12 is provided between the first protrusions 111 and second protrusions 112. The nylon sleeve 12 compensates for machining errors during the processing of the blades 11 and assembly errors during assembly, reducing wear. The pivot 13 passes through each first protrusion 111, second protrusion 112, and nylon sleeve 12, and the end of the pivot 13 is locked with a nut.

[0021] Figure 2 This is a flowchart illustrating a hinge assembly method according to the present invention. Figure 2 As shown, the hinge assembly method provided in this embodiment is used to assemble the above-mentioned hinge. The assembly method includes the following steps: Step S1, component processing; The blade 11 is processed by stamping using a stamping machine, and then polished by a grinding machine to remove burrs. Next, the blade 11 undergoes powder coating to improve its corrosion and rust resistance. This yields the finished blade, ready for subsequent assembly. Simultaneously, the shaft 13 is machined by turning. Additionally, nylon sleeves 12 and thin-film pads 2 are procured and stored in rolls, also awaiting subsequent assembly.

[0022] Step S2, assembly; The finished blade is placed in the placement slot 331 of the corresponding mold 33 to accurately place the blade 11 at the corresponding assembly position. Simultaneously, a nylon sleeve 12 is placed between the first protrusion 111 and the second protrusion 112 of the finished blade; that is, a nylon sleeve 12 is provided between each first protrusion 111 and second protrusion 112. Furthermore, while placing the nylon sleeve 12 between the first protrusion 111 and the second protrusion 112, a thin film pad 2 is also provided at one or both ends of the nylon sleeve 12. The thickness of the thin film pad 2 limits the assembly gap between the nylon sleeve 12 and the corresponding first protrusion 111 or second protrusion 112, ensuring proper fit. Then, the rotating shaft 13 passes through each first protrusion 111, second protrusion 112, nylon sleeve 12, and thin film pad 2. Finally, limits are set at both ends of the rotating shaft 13 to complete the assembly operation.

[0023] Step S3, take film pad 2; Remove the film pad 2 from the hinge 1 assembled in step S2, so that the assembly gap between the nylon sleeve 12 and the first protrusion 111 or the second protrusion 112 is consistent with the thickness of the film pad 2. This ensures the uniformity of the installation gap and avoids the problem of distortion and wear caused by excessive installation gap, making the structural design more reasonable.

[0024] Step S4, pack and store; The finished hinges obtained in step S3 are labeled and bagged and boxed to realize the storage of finished hinges. It is worth noting that before labeling the finished hinges, quality inspection is required to observe quality problems such as paint peeling on the surface and whether the film pad 2 has been removed, to ensure that the labeled and bagged finished hinges are qualified products.

[0025] More specifically, the thin film pad 2 disposed between the nylon sleeve 12 and the corresponding first protrusion 111 or second protrusion 112 is arranged in a strip shape, that is, the thin film pad 2 has a certain length, providing conditions for subsequent roll storage and continuous processing. Furthermore, the thin film pad 2 has several strip-shaped holes 21 arranged in a dotted line along its length, making it easy for the thin film pad 2 to split open from the dotted line holes 21, facilitating both the passage of the rotating shaft 13 and the subsequent removal of the thin film pad 2, resulting in a more rational structural design.

[0026] Figure 3 This is a structural diagram of the equipment used in a hinge assembly method according to the present invention. Figure 3 As shown, the assembly equipment for the hinge 1 provided in this embodiment is used for processing in the above assembly method, and includes a frame 3, a feeding assembly 4, a shim feeding assembly 5, a limiting assembly 6, and a feeding assembly 4.

[0027] Specifically, the frame 3 is placed on the ground, and a platform 31 is installed on the frame 3 as the operator's operating platform. A rotating frame 32 is located in the middle of the platform 31, and two spaced-apart molds 33 are mounted on the rotating frame 32. The rotation of the rotating frame 32 allows the positions of the two ends of the molds 33 to be switched, facilitating the subsequent use of one mold 33 for installation and the other for removing the film pad 2. Furthermore, the molds 33 have placement slots 331 corresponding to the blades 11. These slots are used to place the hinge blades 11, nylon sleeves 12, and other structures, standardizing the position of each component before installation, resulting in more accurate positioning and better assembly.

[0028] Specifically, the feeding assembly 4 includes a blade feeding section 41 and a nylon sleeve feeding section 42. Two sets of blade feeding sections 41 are provided and spaced apart on both sides of the mold 33. The two blade feeding sections 41 respectively grasp the two blades 11 of the hinge 1 and place them into the corresponding placement slots 331. Simultaneously, each set of blade feeding sections 41 moves closer to or further away from the placement slots 331 of the mold 33, facilitating the subsequent grasping and placement of the transported blades 11 into the placement slots 331. Meanwhile, the nylon sleeve feeding part 42 is set on the frame 3 and located beside the blade feeding part 41 and the mold 33, which avoids mutual interference between the blade feeding part 41 and the nylon sleeve feeding part 42. At the same time, it also avoids the problem of being blocked when the mold 33 rotates. The nylon sleeve feeding part 42 moves closer to or further away from the placement groove 331 on the mold 33 in the horizontal direction, that is, the nylon sleeve 12 can transfer the transported nylon sleeve 12 to the corresponding placement groove 331 of the mold 33, thus meeting the automatic feeding requirements of the nylon sleeve 12.

[0029] Specifically, the pad placement assembly 5 is mounted on the frame 3 and located beside the feeding assembly 4, preventing mutual interference between the pad placement assembly 5 and the feeding assembly 4. Simultaneously, the pad placement assembly 5 moves vertically towards or away from the placement groove 331 on the mold 33. The pad placement assembly 5 places the film pad 2 into the gap between the nylon sleeve 12 and the blade 11 within the placement groove 331, ensuring that the installation gap between the first protrusion 111 or the second protrusion 112 on the nylon sleeve 12 and the blade 11 is consistent with the thickness of the film pad 2. Furthermore, the film pad 2, mounted on the pad placement assembly 5, moves towards or away from the placement groove 331 along with the pad placement assembly 5, i.e., the pad placement assembly 5 conveys the film pad 2 into the anti-interference groove, ensuring that the film pad 2 is positioned between the nylon sleeve 12 and the first protrusion 111 or the second protrusion 112.

[0030] Specifically, the limiting component 6 includes a shaft-penetrating part 61 and an end limiting part. The shaft-penetrating part 61 is mounted on the frame 3 and moves horizontally along the direction in which the first protrusion 111 and the second protrusion 112 on the blade 11 alternately engage. That is, when the shaft 13 passes through the first protrusion 111 and the second protrusion 112, the axial direction of the shaft 13 is the direction in which the first protrusion 111 and the second protrusion 112 alternately engage, making the movement direction of the shaft-penetrating part 61 the axial direction of the shaft 13. This provides the conditions for subsequently passing the shaft 13 through the first protrusion 111 and the second protrusion 112. Furthermore, the end limiting part is mounted on the frame 3 and symmetrically arranged with the shaft-penetrating part 61 about the mold 33. That is, the end limiting part can cooperate with the shaft-penetrating part 61 to act on both ends of the shaft 13, providing the conditions for subsequently limiting the ends of the shaft 13. Furthermore, the end limiting part can extend and retract along the movement direction of the through-rotating shaft part 61, so that the movement direction of the end limiting part is consistent with the axial direction of the rotating shaft 13, which facilitates the subsequent installation of the limiting structure at the end of the rotating shaft 13, and the structural design is more reasonable.

[0031] It is worth noting that the feeding assembly 4, the padding assembly 5, and the limiting assembly 6 act on the same mold 33 when the rotating frame 32 rotates, so that the assembly of the blade 11, nylon sleeve 12, film pad 2, and rotating shaft 13 and other structures can be carried out in the same mold 33, making the operation more convenient and the arrangement of each structural component more concentrated, which is conducive to the miniaturization design of the device.

[0032] More specifically, the rotating frame 32 rotatably mounted on the platform 31 includes a main drive shaft 321, a frame 322, and a main rotary actuator 323. In this case, the main drive shaft 321 is designed as a hollow shaft, allowing for installation space for subsequent structures. Furthermore, the main drive shaft 321 is rotatably mounted on the platform 31, satisfying the rotational requirements of the rotating frame 32. Additionally, the main rotary actuator 323 is positioned on the frame 3 and below the platform 31, avoiding the problem of the main rotary actuator 323 occupying a large amount of space on the platform 31. Furthermore, the lower end of the main drive shaft 321 extends to the bottom of the platform 31 and is powered by the main rotary drive 323, that is, the main drive shaft 321 is driven to rotate by the main rotary drive 323. At the same time, the upper end of the main drive shaft 321 extends to the top of the platform 31. The frame 322 is set on the upper end of the main drive shaft 321 and rotates with the main drive shaft 321. The frame 322 expands the mounting carrier of the upper end of the main drive shaft 321. In addition, the mold 33 is mounted on the frame 322, realizing the movement of the mold 33 on the platform 31.

[0033] Figure 4 This is a structural diagram of the blade feeding section according to a preferred embodiment of the present invention. Figure 3 and Figure 4As shown, the blade feeding section 41 in the feeding assembly 4 includes a feeding guide 411, a feeding bracket 412, a vertical sliding member 413, a horizontal sliding member 414, a tilting telescopic driver 415, and a suction cup 416. The feeding guide 411 is mounted on the frame 3, and the other end of the feeding guide 411 is connected to a feeding structure such as a vibrating feeding tray, so that the blade 11 can be transported to the table 31 through the feeding guide 411. At the same time, one end of the feeding guide 411 extends to the side of the rotating frame 32, so that the blade 11 transported through the feeding guide 411 can be transferred to the placement slot 331 of the mold 33. Furthermore, the feeding bracket 412 is set on the frame 3, and the vertical sliding member 413 is set on the feeding bracket 412 and moves up and down in the vertical direction. At the same time, the horizontal sliding member 414 is set on the vertical sliding member 413. The horizontal sliding member 414 moves back and forth between the feeding guide 411 and the mold 33 in one direction in the horizontal plane. This allows the horizontal sliding member 414 to move up and down in the vertical direction under the action of the vertical sliding member 413, and also to move back and forth in the horizontal plane. This provides the conditions for subsequently moving back and forth between the feeding guide 411 and the mold 33 to pick up the blade 11 and place the blade 11 in the placement slot 331. Meanwhile, the tilting telescopic actuator 415 is mounted on the horizontal sliding member 414 and arranged at an angle to the vertical direction. This allows its telescopic shaft to extend obliquely when the tilting telescopic actuator 415 is in motion. Specifically, when the telescopic shaft of the tilting telescopic actuator 415 is in a higher position, it can move away from the mold 33, providing movement and working space for other structural components. When the telescopic shaft of the tilting telescopic actuator 415 is in a lower position, it can move closer to the mold 33, facilitating the placement of the gripped blade 11 into the placement slot 331 of the mold 33. Simultaneously, as the telescopic shaft of the tilting telescopic actuator 415 moves closer to or further away from the mold 33, a suction cup 416 is mounted on the telescopic shaft of the tilting telescopic actuator 415. This allows the suction cup 416 to move along with the telescopic shaft of the tilting telescopic actuator 415, enabling it to perform vertical lifting, horizontal reciprocating movement, and oblique movement. This satisfies the requirement of picking up the blade 11 from the feeding guide 411, transferring it to the mold 33, and placing it into the placement slot 331 of the mold 33. It is worth noting that the vertical sliding member 413, the horizontal sliding member 414, and the tilting telescopic device include, but are not limited to, cylinders, as long as they can achieve linear reciprocating movement, and will not be described in detail here.

[0034] More specifically, since the two sets of blade feeding sections 41 are located on both sides of the mold 33, the feeding brackets 412 of the two sets of blade feeding sections 41 are different. The lower end of the feeding bracket 412 of one of the blade feeding sections 41 passes through the hollow of the drive shaft and is fixedly connected to the frame 3. This ensures both the stable connection between the feeding bracket 412 and the frame 3 and the free rotation of the rotating frame 32, making the structural design more reasonable.

[0035] Figure 5 This is a structural diagram of the nylon sleeve feeding section according to a preferred embodiment of the present invention; as shown. Figure 3 and Figure 5 As shown, the nylon sleeve feeding section 42 in the feeding assembly 4 includes a moving part 421, a guide tube 422, and an opening / closing door 423. The moving part 421 is mounted on the feeding bracket 412 and moves towards or away from the mold 33 along a horizontal direction. When a nylon sleeve 12 needs to be placed onto the mold 33, the moving part 421 can move to a position close to the mold 33, and after placement, it moves away from the mold 33, providing space for the operation of other structural components. Furthermore, the moving part 421 is equipped with several spaced guide tubes 422, allowing the guide rails to follow the movement of the moving part 421. Simultaneously, several nylon sleeves 12 are stored within the guide tubes 422, providing conditions for the nylon sleeves 12 inside the guide tubes 422 to fall into the placement cavity of the mold 33 when the guide tubes 422 approach the mold 33. Moreover, the multiple guide rails allow for the simultaneous feeding of multiple nylon sleeves 12, resulting in higher efficiency. Meanwhile, each conduit 422 is equipped with an opening / closing door 423 at its lower end. The opening / closing door 423 opens or closes the lower end of the corresponding conduit 422. When the opening / closing door 423 is opened, the lower end of the corresponding conduit 422 opens, and the nylon sleeve 12 stored in the conduit 422 falls from the opened lower end into the placement cavity of the mold 33. After one nylon sleeve 12 falls, the opening / closing door 423 closes to prevent other nylon sleeves 12 from falling out of the conduit 422. The structural design is more reasonable. It is worth noting that the moving part 421 can be a cylinder, and the opening / closing door 423 can be a structure with a baffle mounted on the telescopic shaft of the cylinder. As long as it can achieve movement, it is widely used. Therefore, its specific structure will not be described in detail here.

[0036] Figure 6 This is a structural diagram of a gasket assembly according to a preferred embodiment of the present invention. Figure 3 and Figure 6As shown, the pad placement assembly 5 includes a pad support 51, a pad lifting drive 52, a guide plate 53, a film rotating frame 54, a pressure roller 55, an air nozzle 56, and an angle adjustment component 57. The pad support 51 is mounted on the frame 3 and extends above the mold 33 to avoid obstructing its rotation. The pad lifting drive 52 is mounted on the pad support 51 and moves vertically. The guide plate 53 is a strip-shaped plate with a certain length. It is mounted vertically on the lifting shaft of the pad lifting drive, allowing it to move vertically with the drive, thus providing conditions for the lower end of the guide plate 53 to move closer to or further away from the mold 33. The upper end of the guide plate 53 is equipped with a film rotating frame 54. The film pad 2 is rolled up and rotatably mounted on the film rotating frame 54, allowing it to rotate on the guide plate 53 for release. Meanwhile, an angle adjustment component 57 is positioned at the lower end of the guide plate 53, and an air nozzle 56 is mounted on the angle adjustment component 57 and blows air vertically downwards. The angle adjustment component 57 adjusts the direction of air blowing from the air nozzle 56, providing a basis for adjusting the force of the air nozzle 56 blowing the film pad 2. That is, when the film pad 2 needs to be placed between the nylon sleeve 12 and the first protrusion 111 or the second protrusion 112, airflow can be blown out through the air nozzle 56, which drives the film pad 2 to be inserted between the nylon sleeve 12 and the first protrusion 111 or the second protrusion 112, thus meeting the installation requirements of the film pad 2. In addition, the pressure roller 55 is rotatably mounted on the guide plate 53 and located between the film rotating frame 54 and the air nozzle 56. The end of the rolled-up film pad 2 extends to the air nozzle 56 after passing through the pressure roller 55. That is, the release length of the rolled-up film pad 2 is achieved by controlling the rotation of the pressure roller 55, preventing the film pad 2 from being over-released under the action of the air nozzle 56, making the structural design more reasonable. It is worth noting that the pressure roller 55 has its own rotary motor, allowing it to rotate independently and preventing interference with the release length of the film pad 2. Furthermore, the lifting driver can be a cylinder capable of lifting and lowering. The angle adjustment component 57 consists of a rotating rod and a locking nut. The rotating rod is rotatably mounted on the guide plate 53, and a locking nut is located at the end of the rod. Tightening the locking nut locks and unlocks the rotating rod, thus meeting the requirements for fixed operation during adjustment and use.

[0037] Figure 7 This is a structural diagram of the shear portion according to a preferred embodiment of the present invention. Figure 3 and Figure 7As shown, the pad assembly 5 is also provided with a cutting section 58. The cutting section 58 includes scissors 581, a telescopic carriage 582, and a scissor telescopic actuator 583. The telescopic carriage 582 is mounted on the frame 3 and located beside the table 31. The scissor telescopic actuator 583 is mounted on the telescopic carriage 582 and positioned towards the guide plate 53, allowing the telescopic shaft of the scissor telescopic actuator 583 to move closer to or further away from the guide plate 53. Simultaneously, the scissors 581 are mounted on the telescopic shaft of the scissor telescopic actuator 583. The scissors 581 are positioned such that they follow the telescopic shaft of the scissor telescopic actuator 583. When the telescopic shaft of the scissor telescopic actuator 583 moves the scissors 581 towards the guide plate 53, the scissors 581 moves below the guide plate 53 and above the mold 33. This prevents the scissors 581 from impacting the mold 33 while simultaneously cutting the film pad 2 located between the mold 33 and the guide plate 53. It also ensures that the cut film pad 2 retains a certain end, facilitating its subsequent removal. It is worth noting that the scissor telescopic actuator 583 can be a cylinder capable of telescopic movement, and the scissors 581 can be a blade capable of cutting the film pad 2. Therefore, the specific structures of the scissor telescopic actuator 583 and the scissors 581 will not be described in detail here.

[0038] More specifically, the shaft-penetrating portion 61 in the limiting component 6 includes a shaft groove, a shaft push head, and a shaft push driver. The shaft groove is arranged along the direction in which the first protrusion 111 and the second protrusion 112 on the blade 11 are alternately embedded and is located on one side of the mold 33, so that the arrangement direction of the shaft groove is consistent with the axial direction of the subsequently installed shaft 13, facilitating the subsequent insertion of the shaft 13. Furthermore, the shaft push driver is located on the side of the shaft groove away from the mold 33, and the push shaft of the shaft push driver reciprocates along the arrangement direction of the shaft groove. Simultaneously, the shaft push head is slidably placed in the shaft groove, so that when the shaft push head slides within the shaft groove, it can push the shaft 13 placed within the shaft groove to move, thereby allowing the shaft 13 to pass through the first protrusion 111 and the second protrusion 112. Moreover, the shaft push head is connected to the push shaft of the shaft push driver, meaning the shaft push driver provides power for the movement of the shaft push head.

[0039] More specifically, the end limiting part in the limiting component 6 includes a nut sleeve, a nut rotation driver, and a nut push driver. In this case, the nut push driver is positioned on the side of the mold 33 opposite to the rotating shaft groove, meaning the nut push driver and the rotating shaft push driver are located on opposite sides of the mold 33, providing conditions for subsequent action on both ends of the rotating shaft 13. Simultaneously, the nut rotation driver is mounted on the push shaft of the nut push driver, allowing the nut rotation driver to perform telescopic movements following the nut push driver. Furthermore, a nut sleeve is mounted on the drive shaft of the nut rotation driver, allowing the nut sleeve to rotate along with the drive shaft of the nut rotation driver; that is, the nut sleeve can both telescopically move and rotate. Furthermore, the nut sleeve has a receiving cavity to accommodate a nut that is threadedly connected to the end of the rotating shaft 13. Specifically, after the rotating shaft 13 is inserted into the first protrusion 111 and the second protrusion 112 via the rotating shaft push driver, the operator places the nut 131 into the nut sleeve and controls the operation of the nut push driver and the nut rotation driver to tighten the nut 131 onto the end of the rotating shaft 13. It is worth noting that the end of the rotating shaft 13 pushed by the rotating shaft push head itself has a protruding limiting part, eliminating the need for subsequent installation of a limiting part. Also, for aesthetic purposes, the limiting part of the rotating shaft 13 itself has the same shape as the subsequently installed nut 131. Moreover, the nut push driver can be a cylinder, and the nut rotation driver can be a pneumatic motor, resulting in low cost and mature technology.

[0040] More specifically, such as Figure 3 As shown, a pad removal assembly 7 is also provided on the frame 3. At this time, the pad removal assembly 7 is provided on the frame 3 and located next to another mold 33 of the rotating frame 32, so that the hinge 1 after being assembled by the feeding assembly 4, the pad feeding assembly 5 and the limiting assembly 6 can enter and rotate to the pad removal assembly 7, waiting for the subsequent removal of the film pad 2. Furthermore, the gasket removal assembly 7 includes a horizontal sliding frame 71, a vertical telescopic actuator 72, and a gripper 73. The horizontal sliding frame 71 is positioned horizontally above the rotating frame 32 and moves towards or away from the mold 33 in a horizontal direction. Simultaneously, the vertical telescopic actuator 72 is mounted on the horizontal sliding frame 71, and a gripper 73 is installed on the telescopic shaft of the vertical telescopic actuator 72. This gripper 73 can move vertically up and down with the vertical telescopic actuator 72, and also reciprocate horizontally under the action of the horizontal sliding frame 71. This allows the gripper 73 to clamp the end of the film pad 2, pulling the film pad 2 out of the gap between the nylon sleeve 12 and the first protrusion 111 or the second protrusion 112. It is worth noting that both the horizontal sliding frame 71 and the vertical telescopic actuator 72 can be cylinders, sufficient to meet the telescopic movement requirements; therefore, their specific structures will not be described in detail here.

[0041] The hinge assembly method and equipment provided in this embodiment include step S1, component processing; step S2, assembly; step S3, removing the film pad; and step S4, storage and packaging. The assembly is performed using equipment including a feeding assembly 4, a pad feeding assembly 5, and a limiting assembly 6. This method allows for the placement of pre-processed blades 11 and nylon sleeves 12 into corresponding placement slots 331 on the mold 33, the insertion of a film pad 2 between the blades 11 and nylon sleeves 12, and finally, the insertion of a rotating shaft 13. The blades 11 and nylon sleeves 12 are then connected by a threaded lock between the rotating shaft 13 and a nut, thus assembling the hinge 1. Furthermore, the assembly process is automated, meeting the assembly requirements of the hinge 1. The equipment has a simple structure, higher assembly efficiency, and is beneficial for the production, manufacturing, and application of the hinge 1.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
