Description

Technical Field

[0001] This invention relates to the technical field of hardware processing, and in particular to a smart hinge nail-threading device. Background Technology

[0002] Cabinet hinges are installed between the cabinet body and the cabinet door of furniture, allowing the cabinet door to rotate relative to the cabinet body. A damping tube is installed inside the hinge; when the cabinet door is closed relative to the cabinet body, the damping tube acts as a buffer, allowing the cabinet door to close slowly onto the cabinet body. Hinges are often manufactured by assembling multiple parts into a finished hinge using automated hinge assembly machines. During the assembly process, a nailing process is required to allow the parts to hinge together and form the finished hinge. This nailing process includes the nailing of strip-shaped connecting nails and the nailing of U-shaped nails. The U-shaped nailing mechanism is the core execution unit of the U-shaped nailing process, mainly used to insert the two legs of the U-shaped nail axially into the hinge holes of the cup head and the star-shaped fitting. In the process of inserting a U-nail, the U-nail first passes through a vibratory feeder and a feeding track, then enters the nail carrier. The nail carrier is then driven to the nail pusher to hit the hinged semi-finished product. However, if the cup head and the plum blossom part or the cup head main body and the buffer assembly are misaligned, the U-nail may get stuck during insertion. That is, the U-nail gets stuck between the nail carrier and the hinge semi-finished product. As a result, it is necessary to remove the hinge semi-finished product being processed from the fixture and then remove the U-nail from the nail carrier and the hinge semi-finished product to pull out the U-nail and repeat the nail insertion process. The disassembly method is cumbersome and increases the workload. In order to avoid the need to remove the U-nail by disassembling the equipment, this invention provides an intelligent hinge nail insertion device. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that in the existing nail-threading mechanism for U-nails, when the U-nail is stuck between the nail carrier and the hinge semi-finished product, it is necessary to disassemble the hinge semi-finished product being processed from the fixture in order to remove the U-nail from the nail carrier and the hinge semi-finished product. The disassembly method is cumbersome and increases the workload. In order to avoid the need to remove the U-nail by disassembling the hinge semi-finished product, the present invention provides an intelligent hinge nail-threading device.

[0004] To achieve the above objectives, this invention discloses an intelligent hinge nail-threading device, comprising a base frame, a nail-carrying component, a nail-pushing component, a nail-pushing power component, and a support component. A U-shaped nail is placed on the nail-carrying component. The nail-pushing power component is installed on the base frame and drives the nail-pushing component. The nail-pushing component pushes the U-shaped nail toward the hinge semi-finished product, and the U-shaped nail passes through the nail hinge hole of the hinge semi-finished product. The nail-carrying component is slidably connected to the support component along the moving direction of the U-shaped nail. When the U-shaped nail is stuck in the hinge semi-finished product, the nail-carrying component slides backward to make room, so that the U-shaped nail is removed.

[0005] A further embodiment includes a nail-carrying power component, which is mounted on the base frame and drives the nail-carrying component to slide along the moving direction of the U-shaped nail.

[0006] A further embodiment includes a swing arm with a swing arm strip-shaped hole, a nail carrier with a nail carrier protrusion, the nail carrier protrusion being slidably and rotatably connected to the swing arm strip-shaped hole, the swing arm being hinged to the support member, the pushed swing arm rotating around the hinge axis, and the swing arm driving the nail carrier to slide through the swing arm strip-shaped hole.

[0007] A further embodiment is that the nail-carrying power component is vertically mounted on the base frame, and the telescopic component of the nail-carrying power component vertically drives the swing-linking component, which in turn pushes the swing-linking component to rotate around the hinge axis.

[0008] A further embodiment is that the pendulum member is provided with a pendulum protrusion, and the telescopic member is provided with a telescopic strip-shaped hole. The telescopic strip-shaped hole and the pendulum protrusion are rotatably connected, and the telescopic member drives the pendulum member to rotate around the hinge axis through the telescopic strip-shaped hole.

[0009] A further embodiment includes a lower locking member and an upper locking member. The lower locking member is installed on the upper end face of the telescopic member, and the upper locking member is lockably slidable on the lower locking member. The telescopic strip-shaped hole is formed in the upper locking member.

[0010] A further embodiment is that the upper locking member has an upper central hole, the lower locking member has a lower central hole, and the top of the telescopic member is provided with a bolt. The bolt passes through the lower central hole and the upper central hole in sequence and is screwed into the nut to lock the relative positions of the upper locking member and the lower locking member.

[0011] A further embodiment is that the support member has a support groove, and the connecting member is hinged to the support member within the support groove.

[0012] A further embodiment is that the nail carrier is provided with a guide protrusion, and the support member is provided with a guide groove. The guide protrusion is slidably connected to the guide groove, so that the nail carrier is slidably connected to the support member along the moving direction of the U-shaped nail.

[0013] A further embodiment is that the nail carrier has a nail carrier hole, the U-shaped nail is placed in the nail carrier hole, and the nail pusher passes through the nail carrier hole to push the U-shaped nail to the hinge semi-finished product.

[0014] A further embodiment includes a receiving component, which is installed on the base frame. The receiving component has a receiving hole, the shape of which is adapted to the shape of the pusher. The pusher passes through the receiving hole and the nail-carrying hole in sequence.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: when the U-nail is stuck in the hinge semi-finished product, that is, when the U-nail is stuck between the carrier and the hinge semi-finished product, the carrier power component drives the carrier to slide backward, so that the carrier can slide backward to make way, and slide backward along the movement direction of the U-nail, so that the U-nail is separated from the carrier, thereby allowing the U-nail to be pulled out from the hinge semi-finished product, or the U-nail can fall off the hinge semi-finished product, avoiding the need to disassemble the equipment components to pull out the U-nail, and improving the convenience of removing the U-nail.

[0016] Specifically, when it is necessary to push the pin carrier closer to the hinge semi-finished product on the fixture, the telescopic component of the pin carrier power component extends vertically upward, driving the connecting cam to rotate through the telescopic strip hole. At the same time, the connecting cam also rotates around the hinge axis. The rotating connecting cam drives the pin carrier cam through the connecting strip hole, and the pin carrier cam then drives the pin carrier closer to the hinge semi-finished product. The pin pusher then pushes the U-pin onto the hinge semi-finished product. When it is necessary to make the pin carrier slide back, the telescopic component of the pin carrier power component retracts vertically, driving the connecting cam to rotate through the telescopic strip hole. At the same time, the connecting cam also rotates around the hinge axis. The rotating connecting cam drives the pin carrier cam through the connecting strip hole, and the pin carrier cam then drives the pin carrier away from the hinge semi-finished product, so that the pin carrier slides back.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the following will be combined with... Figure 1-8 The state shown is described in terms of orientation and structure.

[0020] The following will combine Figure 1-8 The invention will be further described in detail with reference to the accompanying drawings.

[0021] Reference Figure 1-8 As shown, a hinge intelligent nail-threading device includes a base frame 1, a nail-carrying component 2, a nail-pushing component 3, a nail-pushing power component 4, and a support component 5. The base frame 1 provides support. A U-nail 202 is placed on the nail-carrying component 2. The nail-pushing power component 4 is installed on the base frame 1 and drives the nail-pushing component 3. The nail-pushing component 3 pushes the U-nail 202 toward the hinge semi-finished product 201, and the U-nail 202 passes through the nail hinge hole of the hinge semi-finished product 201, thereby installing the U-nail 202 onto the hinge semi-finished product 201. The nail-carrying component 2 of the present invention moves along the U-nail 202. The U-nail 202 is slidably connected to the support member 5 in the direction of movement. When the U-nail 202 is stuck in the hinge semi-finished product 201, that is, when the U-nail 202 is stuck between the carrier member 2 and the hinge semi-finished product 201, the carrier member 2 can slide backward to make room, and slide backward along the direction of movement of the U-nail 202, so that the U-nail 202 is separated from the carrier member 2, thereby allowing the U-nail 202 to be pulled out from the hinge semi-finished product 201, or the U-nail 202 can fall off the hinge semi-finished product 201, improving the convenience of disassembling the U-nail 202.

[0022] This invention includes a turntable 17, a vibratory feeder 13, a feeding guide rail 14, a conveying cylinder 15, and a fixture 16. The turntable 17 is rotatably mounted on a base frame 1. Multiple sets of fixtures 16 are mounted on the turntable 17. The conveying cylinder 15 is mounted on the base frame 1 and drives the support member 5 to move. The U-nail 202 slides from the vibratory feeder 13 into the feeding guide rail 14. After the U-nail 202 enters the nail carrier 2 from the feeding guide rail 14, the conveying cylinder 15 drives the support member 5 and the nail carrier 2 on the support member 5 to a preset position for nail insertion, so that the nail pusher 3 can push the U-nail 202 on the nail carrier 2 to the hinge semi-finished product 201 on the fixture 16.

[0023] In order to enable the nail carrier 2 to slide automatically and improve the degree of automation, the present invention includes a nail carrier power component 6. The nail carrier power component 6 is installed on the base frame 1 and drives the nail carrier 2 to slide along the moving direction of the U-nail 202. The nail carrier power component 6 can be a linear motor or a cylinder. By setting the nail carrier power component 6, the nail carrier power component 6 drives the nail carrier 2 to slide backward so as to pull the U-nail 202 out of the hinge semi-finished product 201.

[0024] To facilitate the arrangement of various components, this invention provides an arrangement structure for vertically mounting the nail-carrying power component 6. Specifically, this invention includes a swing-linking component 7, which has a swing-linking strip-shaped hole 71. The nail-carrying component 2 has a nail-carrying protrusion 21, which is slidably and rotatably connected to the swing-linking strip-shaped hole 71. The swing-linking component 7 is hinged to the support component 5. The nail-carrying power component 6 is vertically mounted on the base frame 1. The telescopic component 61 of the nail-carrying power component 6 vertically pushes the swing-linking component 7. The pushed swing-linking component 7 rotates around the hinge axis 72. The swing-linking component 7 carries the nail through the swing-linking strip-shaped hole 71. When the moving nail 2 slides, and it is necessary to push the nail 2 closer to the hinge semi-finished product 201 on the fixture 16, the telescopic part 61 of the nail-carrying power component 6 extends vertically upward, driving the swing member 7 to rotate around the hinge axis 72. The rotating swing member 7 drives the nail-carrying protrusion 21 through the swing strip hole 71. The nail-carrying protrusion 21 then drives the nail 2 closer to the hinge semi-finished product 201. The nail pusher 3 then pushes the U-nail 202 to the hinge semi-finished product 201. Conversely, when it is necessary to make the nail 2 slide back, the telescopic part 61 of the nail-carrying power component 6 retracts vertically.

[0025] The swing member 7 is provided with a swing protrusion 73, and the telescopic member 61 is provided with a telescopic strip hole 611. The telescopic strip hole 611 and the swing protrusion 73 are slidably and rotatably connected. The telescopic member 61 drives the swing member 7 to rotate around the hinge axis 72 through the telescopic strip hole 611. With the above configuration, when it is necessary to push the nail carrier 2 close to the hinge semi-finished product 201 on the fixture 16, the telescopic member 61 of the nail carrier power member 6 extends vertically upward, drives the swing protrusion 73 to rotate through the telescopic strip hole 611, and at the same time, the swing member 7 also rotates around the hinge axis 72. The rotating swing member 7 passes through the swing strip hole. 71 drives the nail carrier cam 21, which in turn drives the nail carrier 2 to approach the hinge semi-finished product 201. The nail pusher 3 then pushes the U-nail 202 to the hinge semi-finished product 201. When it is necessary to retract the nail carrier 2, the telescopic member 61 of the nail carrier power member 6 retracts vertically. At the same time, it drives the swing arm 73 to rotate through the telescopic strip hole 611. Simultaneously, the swing arm 7 also rotates around the hinge axis 72. The rotating swing arm 7 drives the nail carrier cam 21 through the swing strip hole 71. The nail carrier cam 21 then drives the nail carrier 2 away from the hinge semi-finished product 201, so that the nail carrier 2 can retract and slide.

[0026] Since the thickness of the connecting member 7 can be adjusted according to actual needs, adjusting the thickness of the connecting member 7 requires adjusting the position of the telescopic member 61 of the carrier pin power member 6 to adapt it to the connecting member 7. However, this adjustment method is too cumbersome. In order to solve the above problems, the present invention includes a lower locking member 8 and an upper locking member 9. The lower locking member 8 is fixedly installed on the upper end face of the telescopic member 61. The upper locking member 9 can be locked and slides along the axial direction of the telescopic strip hole 611 on the lower locking member 8. The telescopic strip hole 611 is opened in the upper locking member 9. When adjusting the thickness of the connecting member 7, the upper locking member 9 can be adjusted to adapt to the connecting member 7 of different thicknesses by adjusting the relative position of the upper locking member 9 on the lower locking member 8.

[0027] It should be noted that, in order to better illustrate the mechanism of the present invention, the turntable 17 and the base frame 1 in the accompanying drawings have been cross-sectionally processed.

[0028] The present invention also provides a method for locking the relative positions of the upper locking member 9 and the lower locking member 8. Specifically, the upper locking member 9 of the present invention has an upper central hole, which is strip-shaped and extends along the axial direction of the connecting strip hole 71. The lower locking member 8 has a lower central hole. The top of the telescopic member 61 is provided with a bolt 612. The bolt 612 passes through the lower central hole and the upper central hole in sequence and is screwed to the nut 10 to lock the relative positions of the upper locking member 9 and the lower locking member 8. When it is necessary to adjust the relative positions of the upper locking member 9 and the lower locking member 8 to adapt to the connecting members 7 of different thicknesses, the nut 10 is loosened and the upper locking member 9 is adjusted along the axial direction of the connecting strip hole 71. At the same time, the bolt 612 also moves relative to the connecting strip hole 71. After the adjustment is completed, the nut 10 is locked again to lock the upper locking member 9 and the lower locking member 8 relative to each other.

[0029] In order to improve the stability of the connection between the connecting member 7 and the support member 5, the support member 5 of the present invention has a support groove 51, the connecting member 7 is hinged to the support member 5 in the support groove 51, and part of the side of the connecting member 7 to the side of the support groove 51 is hollowed out to provide space for the upper locking member 9 to be connected to the connecting member 7.

[0030] To improve the stability of the relative sliding between the nail carrier 2 and the support member 5, the nail carrier 2 of the present invention is provided with a guide protrusion 22, and the support member 5 is provided with a guide groove 52. The shape of the guide protrusion 22 and the shape of the guide groove 52 are adapted to each other. The guide protrusion 22 is slidably connected to the guide groove 52 so that the nail carrier 2 is slidably connected to the support member 5 along the moving direction of the U-shaped nail 202. When the nail carrier 2 is slidably connected to the support member 5 along the moving direction of the U-shaped nail 202, the guide groove 52 and the guide protrusion 22 play a guiding role, thereby improving the stability of the relative sliding between the nail carrier 2 and the support member 5.

[0031] The nail carrier 2 of the present invention is provided with a nail carrier hole 23. The U-nail 202 is placed in the nail carrier hole 23. The nail pusher 3 passes through the nail carrier hole 23 to push the U-nail 202 to the hinge semi-finished product 201. With the above arrangement, when it is necessary to push the U-nail 202 to the hinge semi-finished product 201, the nail pusher 4 extends into the nail carrier hole 23 and pushes the U-nail 202 in the nail carrier hole 23 onto the hinge semi-finished product 201 so that the U-nail 202 passes through the hinge semi-finished product 201.

[0032] When the pusher 3 extends into the nail-carrying hole 23, a portion of the pusher 3 protrudes between the nail-carrying member 2 and the pusher 4. To make the process of the pusher 3 penetrating into the nail-carrying hole 23 more stable, the present invention also includes a receiving member 11. The receiving member 11 is installed on the base frame 1 and has a receiving hole 111. The shape of the receiving hole 111 is adapted to the shape of the pusher 3. The pusher passes through the receiving hole 111 and the nail-carrying hole 23 in sequence. With the above arrangement, when the pusher 3 needs to push the U-nail 202, the pusher 4 drives the pusher 3 to pass through the receiving hole 111 and then extend into the nail-carrying hole 23 to push the U-nail 202. The receiving hole 111 serves to receive the pusher 3.

[0033] The pusher component 4 is a pusher cylinder, which can provide greater driving force for the pusher component 3 to drive the U-nail 202.

[0034] The nail-carrying power component 6 is a nail-carrying cylinder, which can therefore provide a greater driving force for the sliding of the nail-carrying component 2 relative to the support component 5.

[0035] Since the nail-carrying power component 6 needs to move synchronously with the support component 5, the present invention also includes an assembly plate 12. The assembly plate 12 is installed on the support component 5, and the cylinder 62 of the nail-carrying power component 6 is installed on the assembly plate 12. When the U-shaped nail 202 of the feeding guide rail 14 enters the nail-carrying component 2, the conveying cylinder 15 drives the support component 5 and the nail-carrying component 2 to move to the position of the nail-pushing component 3. The nail-carrying power component 6 moves synchronously with the support component 5 through the assembly plate 12, thereby realizing the synchronous movement of the nail-carrying power component 6 and the nail-carrying component 2.

[0036] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They cannot be used to limit the scope of protection of the present invention. All modifications made according to the spirit of the main technical solution of the present invention should be covered within the scope of protection of the present invention.
