Description

Technical Field

[0001] This utility model relates to the field of nailing machine technology, and in particular to a magnet mechanism for a nailing machine. Background Technology

[0002] In the process of mounting the back panel of the automotive display screen, the vacuum nozzle at the end of the machine is used to pick up the cylindrical screws from the vibratory plate mounting mechanism. Then, the robotic arm smoothly transports the cylindrical screws into the designated nail holes on the back panel according to the preset path. The product with nails is transported to the riveting mechanism by the action of the transport guide rail. The riveting mechanism firmly rivets the cylindrical screws to the back panel of the automotive display screen.

[0003] However, in the above process, the back panel of the automotive display screen needs to be sent to the next processing point for riveting along the transport guide rail with the movement of the chain. However, due to the vibration that the chain set on the transport guide rail may generate during operation, the cylindrical screw and the back panel are prone to relative movement. In fact, when the vibration of the chain reaches a certain level, the cylindrical screw may even fall out of the pre-drilled hole. This not only interrupts the riveting process, but may also cause missing screws in the product, which seriously affects the subsequent riveting operation and the quality of the final product. Therefore, a magnet mechanism for the riveting machine is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem of missing nails caused by the chain vibration of cylindrical screws in the existing technology, and to propose a magnet mechanism for nailing machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnet mechanism for a nailing machine includes a main support. A robotic arm is fixedly connected to the top of the main support, and a vacuum pump is fixedly connected to the end of the robotic arm. Multiple guide rail brackets are fixedly connected to the top of the main support. A transport guide rail is fixedly connected between two of the guide rail brackets. A drive motor is fixedly connected to the top of the main support. The two transport guide rails are connected to the drive motor via transmission. A tooling base plate is slidably arranged between the two transport guide rails. A product support plate is installed on the top of the tooling base plate. A back plate is provided on the product support plate. A limit fixing assembly is provided between the tooling base plate and the product support plate. The limit fixing assembly is used to keep the cylindrical screw stable during transportation. The limit fixing assembly includes a positioning post installed between the tooling base plate and the product support plate, multiple magnetic components installed inside the positioning post, and a positioning head fixedly connected to the top of the positioning post.

[0007] The above technical solution further includes:

[0008] The tooling base plate has multiple mounting holes that are fixedly connected to the positioning posts. The product support plate is slidably connected to the positioning posts. The positioning head passes through the product support plate and is provided with a cylindrical screw at one end near the back plate.

[0009] The limiting and fixing assembly also includes a fixing cylinder that is slidably disposed inside the positioning post, and the fixing cylinder and the positioning post are connected by a plurality of fixing bolts through a common thread.

[0010] The positioning post is slidably connected to a spring and a telescopic slide rod on its inner side. The telescopic slide rod is located inside the spring, and a base is fixedly connected to both the telescopic slide rod and the spring.

[0011] The magnetic components are arranged in a circumferential array, and the end of the positioning post near the positioning head has multiple slots. The number of slots is consistent with the number of magnetic components, and the magnetic components slide relative to the slots.

[0012] The base slides relative to the inner side of the positioning post, and a plurality of magnetic components are disposed on the top of the base.

[0013] The positioning head has a recessed groove that slides on its inner side, and a limiting head is rotatably connected to the inner side of the positioning head. The limiting head and the recessed groove slide relative to each other.

[0014] An electric telescopic rod is fixedly connected to the inner top of the positioning column. The telescopic end of the electric telescopic rod is fixedly connected to the notch, and the telescopic end of the electric telescopic rod slides relative to the positioning head.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the detachable magnetic component in the limiting and fixing assembly can tightly attract the cylindrical screw and effectively prevent the screw from falling off. The detachable magnetic component allows maintenance personnel to easily replace the demagnetized magnetic component without having to disassemble the entire fixing assembly in a complicated manner, which greatly reduces the maintenance difficulty and time cost.

[0017] 2. In this utility model, by using the set limiting head and notch, the cylindrical screw can be limited and fixed from the inside when it is fitted onto the positioning head. Combined with the adsorption effect of the magnetic component, the probability of the cylindrical screw falling off is further reduced, ensuring production. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figures 1-7As shown, the present invention proposes a magnet mechanism for a nailing machine, including a main support 1, a mechanical arm 2 fixedly connected to the top of the main support 1, a vacuum pump 3 fixedly connected to the end of the mechanical arm 2, multiple guide rail fixing frames 8 fixedly connected to the top of the main support 1, a transport guide rail 5 fixedly connected between two guide rail fixing frames 8, a drive motor 4 fixedly connected to the top of the main support 1, a transmission connection between two transport guide rails 5 and the drive motor 4, a tooling base plate 6 slidably arranged between two transport guide rails 5, a product support plate 7 installed on the top of the tooling base plate 6, a back plate 9 provided on the product support plate 7, a limit fixing component provided between the tooling base plate 6 and the product support plate 7, the limit fixing component is used to keep the cylindrical screw 10 stable during transportation, the limit fixing component includes a positioning post 11 installed between the tooling base plate 6 and the product support plate 7, multiple magnetic parts 16 installed inside the positioning post 11, and a positioning head 13 fixedly connected to the top of the positioning post 11;

[0029] First, the multi-directional movement capability of the robotic arm 2 is utilized, while the vacuum pump 3 picks up the cylindrical screw 10 from the vibratory plate nailing mechanism and places the cylindrical screw 10 on the multiple positioning holes on the back plate 9. The cylindrical screw 10 is then fixed by the limiting and fixing components to ensure stable operation during transportation and prevent it from falling off the positioning head 13 due to vibration generated during the operation of the transport guide rail 5.

[0030] Multiple mounting holes 12 are provided through the tooling base plate 6. The mounting holes 12 are fixedly connected to the positioning post 11. The product support plate 7 is slidably connected to the positioning post 11. A cylindrical screw 10 is provided at the end of the positioning head 13 that passes through the product support plate 7 and is close to the back plate 9.

[0031] During operation, the back plate 9 is placed on the product support plate 7 by passing through the positioning head 13 and using the positioning column 11 and positioning head 13, which facilitates the subsequent placement of the cylindrical screw 10 on the vacuum pump 3.

[0032] The limiting and fixing assembly also includes a fixing cylinder 20 that is slidably disposed inside the positioning post 11, and the fixing cylinder 20 and the positioning post 11 are connected by a plurality of fixing bolts 14 through a common thread.

[0033] A spring 19 and a telescopic slide rod 18 are slidably connected to the inner side of the positioning post 11. The telescopic slide rod 18 is located inside the spring 19, and a base 15 is fixedly connected between the telescopic slide rod 18 and the spring 19.

[0034] The magnetic components 16 are arranged in a circumferential array. The positioning post 11 has multiple slots 17 at one end near the positioning head 13. The number of slots 17 is the same as that of the magnetic components 16. The magnetic components 16 slide relative to the slots 17.

[0035] The base 15 slides relative to the inner side of the positioning post 11, and multiple magnetic components 16 are disposed on the top of the base 15;

[0036] First, when installing the magnetic component 16, place the multiple magnetic components 16 into the designated slots 17, then press down on the magnetic component 16. The magnetic component 16 will contact the base 15. As the magnetic component 16 moves down, it will cause the base 15 to move synchronously, compressing the spring 19. At the same time, the telescopic slide rod 18 will shorten. During the downward movement of the base 15, the fixing cylinder 20 will move closer to and contact the inner bottom of the positioning post 11. Then, using the multiple fixing bolts 14, the fixing cylinder 20 and the positioning post 11 will be fixed together. When it is necessary to replace the magnetic component 16, release the threaded connection between the fixing bolts 14 and the fixing cylinder 20 and the positioning post 11. The magnetic component 16 will automatically pop out, making it convenient to replace the demagnetized magnetic component 16.

[0037] The inner side of the positioning head 13 is provided with a notch 22, and the inner side of the positioning head 13 is rotatably connected to a limiting head 23, and the limiting head 23 and the notch 22 slide relative to each other.

[0038] An electric telescopic rod 21 is fixedly connected to the top inner side of the positioning column 11. The telescopic end of the electric telescopic rod 21 is fixedly connected to the notch 22. The telescopic end of the electric telescopic rod 21 slides relative to the positioning head 13.

[0039] When the cylindrical screw 10 is placed on the positioning post 11, it is attracted by multiple magnetic components 16 to prevent it from falling off the positioning head 13. At the same time, the electric telescopic rod 21 is driven to move the notch 22 upward. During the upward movement of the notch 22, the head of the limiting head 23 rotates on the positioning head 13, so that the tail end of the positioning head 13 slides on the notch 22. The squeezing force of the limiting head 23 on the cylindrical screw 10 further prevents the cylindrical screw 10 from falling off.

[0040] In this embodiment, multiple magnetic components 16 are placed in the slots 17. Pressing down the magnetic components 16 causes the base 15 to move synchronously, compressing the spring 19. The base 15 moves down, causing the fixing cylinder 20 to move down. Rotating the fixing bolt 14 fixes the fixing cylinder 20 and the positioning post 11 together. When it is necessary to replace the magnetic component 16, the threaded connection between the fixing bolt 14, the fixing cylinder 20, and the positioning post 11 is released, and the magnetic component 16 automatically pops out, making it convenient to replace the demagnetized magnetic component 16. When the cylindrical screw 10 is placed on the positioning post 11, it prevents the cylindrical screw 10 from falling off the positioning head 13. At the same time, the electric telescopic rod 21 drives the notch 22 to move up, causing the limiting head 23 to contact the cylindrical screw 10 and generate a squeezing force, further preventing the cylindrical screw 10 from falling off. When the cylindrical screw 10 is riveted in the subsequent process, the electric telescopic rod 21 resets, driving the limiting head 23 to reset as well.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
