Description

Technical Field

[0001] The present invention relates to the technical field of hinge assembly, and particularly to an intelligent hinge production device. Background Art

[0002] Hinges are usually formed by riveting or screwing multiple components such as arm bodies, bases, cup heads, four-hole parts, etc. There are also tiny parts such as torsion springs, plastic round tubes, U nails, etc. at the joints of each component. For hinges with a buffering function, an inner strip assembly containing a buffer oil pipe needs to be further installed. During the overall assembly of the hinge, the connection holes of each component need to be aligned for assembly. However, the hinge components are fragmented and irregular, and usually require manual adjustment and positioning, resulting in low production efficiency, long production cycles, low positioning accuracy, and difficulty in ensuring the yield rate. Since the plastic round tubes are too small, it is difficult for manual workers to grasp them. When placed on ordinary carriers for assembly, due to their too light weight, they are prone to roll off with slight vibration. Other components also have problems such as irregular shapes, small sizes, and light weights, making it difficult to automatically feed them. Currently, manual positioning and feeding and machine nail insertion are mostly used.

[0003] Currently, the carriers on the conveyor line go through several workstations for feeding or assembly, etc., and finally produce finished products at the end of the conveyor line, but several problems are brought: 1. In the existing hinge assembly production line, internal parts of the hinge such as plastic round tubes and inner strip assemblies are assembled last with the arm body. During the production process, the carrier is used as the carrier for placing the internal parts of the hinge. Different parts need to be set with different accommodation positions and each position needs to be accurately positioned. Therefore, when assembling different types of hinges or improving the hinges on the existing production line, all the carriers on the entire production line need to be redesigned, which is time-consuming and laborious; 2. Once a problem occurs at a certain workstation, the corresponding processed semi-finished product becomes a defective product. If the subsequent workstations still continue to feed or assemble the defective product, not only the final output will be defective, but also many workstations after the problem workstation may be damaged. All the workstations after the problem workstation are doing useless work, resulting in serious waste; 3. There are many workstations, making it difficult to use software programs to coordinately control all workstations, with high costs and poor software stability; 4. Currently, most of them automatically alarm when a problem occurs at a workstation, pause all workstations on the entire production line, and then manual workers handle it, with very low efficiency; 5. There are also cases where each carrier is coded, and by recording the code of the problem carrier, subsequent each workstation receives an instruction not to perform the next feeding or assembly on the semi-finished product on that carrier. This method has a high cost.

[0004] A patent application filed by the present applicant on January 12, 2021, with the patent application number 2021100405722 and the title "An Automatic Assembly Device for Hinges". In this device, positioning surfaces are provided for the carriers of each component of the hinge to place and position them. After positioning, the connection holes on each component are automatically aligned, and connection and assembly can be achieved simply by inserting pins. It can effectively solve the problems in the prior art that the pins are prone to skew during insertion, resulting in assembly failure or damage to the workpiece. For other components such as plastic round tubes, they are too small for manual grasping. When placed on ordinary carriers for assembly, due to their light weight, they are easily rolled off by slight vibration. Other components also have problems such as irregular shapes, small sizes, and light weights, making it difficult to automatically load materials. However, there is still room for optimization: when assembling different types of hinges or improving the hinges on the existing production line, the carriers need to be adjusted, and the efficiency is not high. In view of this, the existing production devices for hinges still need further improvement. Summary of the Invention

The top surface of the base carrier has a convex position matching the shape of the base bottom surface, and the convex position is used for placing the base. The bases are slidably arranged in the base slideway 102. The base jaw 104 picks up the base from the base slideway 102 and transports it to the convex position of the base carrier staying below it. Then the base rotating disk 101 rotates, and the base carrier with the base rotates to below the arm body jaw 105. The arm bodies are slidably arranged in the arm body slideway 103.

The first and second staple parts 301 and 302 fix the inner strip assembly and the triangular piece on the arm body with high positioning accuracy, facilitating the passing of the connecting nails through the arm body, plastic round tube, and inner strip assembly; several stoppers 303 are arranged at the top of one side of the base 301, and the stoppers 303 have notches. The core holes of the nail holes on the arm body respectively face the notches on the stoppers 303. The stoppers 303 can assist in fixing the connecting nails, and the connecting nails are not easily detached before riveting; the positioning posts 304 are arranged in the middle of the groove, and the positioning posts 304 match the positioning holes on the arm body, with high inclusiveness for the same type of hinge, and there is no need to replace the vehicle for different hinges; the reading rod 305 is slidably inserted at the rear end of the base 301, and both ends of the reading rod 305 have limit blocks. The assembly vehicle 30 is positioned by fitting the entire outer wall of the arm body, making the opening of the arm body face upward, facilitating the placement of the inner strip assembly into the arm body through the opening of the arm body for installation. The first and second staple parts 301 and 302 on the assembly vehicle 30 pass through the nail holes and enter the arm body to fix the inner strip assembly placed inside the arm body.

[0051] As Figure 1 shown, the assembly vehicle 30 moves on the conveyor device 40 and first passes through the four-hole part and torsion spring feeding mechanism 50. The four-hole part and torsion spring feeding mechanism 50 are arranged on one side of the conveyor device 40. The four-hole part and torsion spring feeding mechanism 50 includes: a torsion spring slideway 501, a four-hole part slideway 502, a four-hole part feeding jaw 503, and a torsion spring feeding jaw 504; the torsion springs are slidably arranged in the torsion spring slideway 501; the four-hole parts are slidably arranged in the four-hole part slideway 502; the four-hole part feeding jaw 503 first grabs the four-hole part from the four-hole part slideway 502 and transports it to the assembly vehicle 30 and is not fixedly connected to the front end of the arm body; then the torsion spring feeding jaw 504 grabs the torsion spring from the torsion spring slideway 501 and transports it to the assembly vehicle 30. The connection holes of the torsion spring are aligned with the connection holes of the arm body and the four-hole part, and the first nail inserting machine 601 inserts the connecting nails into the connection holes of the four-hole part, torsion spring, and arm body.

[0052] As Figure 6 、 7 As shown in Figures 8, etc., subsequently, the assembly vehicle 30 passes through the inner strip assembly and round tube feeding mechanism 70. The inner strip assembly and round tube feeding mechanism 70 includes an inner strip assembly feeding slideway 701, an inner strip jaw 702, a round tube feeding slideway 703, a round tube jaw 704, a combined rotating disk 705, a combined jaw 706, and a compression torsion spring block 707. As Figure 9As shown in the figure, the inner strip feeding chute includes a bottom supporting strip and several top pressing strips. The inner strip assemblies are arranged in a sliding manner between the bottom supporting strip and the top pressing strips. The top pressing strips respectively match at least two recesses of the inner strip assemblies to limit and align the inner strip assemblies; the inner strip gripper 702 is arranged above the end of the inner strip assembly feeding chute 701, and clamps the inner strip assembly located at the end of the inner strip assembly feeding chute 701 onto the combined rotating disk 705. The inner strip gripper 702 includes a first and a second finger that move closer or farther apart, and a second clamping groove. On the opposite end faces of the first and second fingers, there are also left and right concave surfaces respectively for clamping the oil pipes of the inner strip assembly. The second clamping groove has magnetism, and the second clamping groove sucks the laminations of the inner strip assembly from the front and the rear. As Figure 10 As shown in the figure, the round pipe feeding chute 703 includes a first and a second round pipe chute. The plastic round pipes are respectively arranged in a sliding manner within the first and second round pipe chutes. The ends of the first and second round pipe chutes are aligned in height and are close to each other. The ends of the first and second round pipe chutes respectively have notches, and the core holes of the plastic round pipes face the notches; the round pipe gripper 704 includes a left and a right finger that move closer or farther apart. On the left and right fingers, there are respectively opposite first and second pins for passing through the notches and inserting into the core holes of the plastic round pipes located at the ends of the first and second round pipe chutes, and clamping them onto the combined rotating disk 705. As Figure 11 As shown in the figure, on the combined rotating disk 705, there is a material waiting tool 7051 that can accommodate the inner strip assembly and the plastic round pipe. Figure 12 As shown in the figure, the combined gripper 706 is arranged between the assembly carrier 30 and the combined rotating disk 705. The combined gripper 706 clamps the inner strip assembly and the plastic round pipe on the combined rotating disk 705 onto the assembly carrier 30; the combined gripper 706 includes an oil pipe limiting block, a plastic gripper, and a first clamping groove. The oil pipe limiting block includes four limiting blocks that move closer or farther apart.

As Figure 13 As shown in the figure, the compression torsion spring block 707 is arranged above the assembly carrier 30. The compression torsion spring block 707 presses down the end of the torsion spring and jacks up the lamination of the inner strip assembly, making the end of the torsion spring lower than the plastic round pipe. The connection holes on the lamination are aligned with the connection holes of the plastic round pipe and the hinge arm body. The second riveting machine 602 inserts the connecting rivets into the connection holes on the hinge arm body, the plastic round pipe, and the lamination of the inner strip assembly.

[0053] As Figure 14 As shown in the figure, then the assembly carrier 30 passes through the pressing mechanism 80. The pressing mechanism 80 includes two pressing blocks 90. The two pressing blocks 90 successively press down the oil pipe and the lamination of the inner strip assembly, and then the assembly carrier 30 passes through the riveting mechanism 60.

[0054] As Figure 15As shown in the figure, each working station of the conveying device 40 is equipped with a working station detection device for detecting whether the working station has been successfully operated. The working station detection device is set according to different requirements of different working station processes. For example, an infrared ranging sensor is used to detect whether the position of the component is at the specified position. The working station detection device is communicatively connected to the marking device 100; the marking device 100 includes a push block telescopically arranged on one side of the assembly carrier 30 at the same initial position as the reading rod 305. When the push block extends, it pushes the reading rod 305 to slide, causing the reading rod 305 to deflect to the other side of the assembly carrier 30 opposite to the initial position of the reading rod 305; the marking detection device 11 is arranged on the other side of the assembly carrier 30 opposite to the initial position of the reading rod 305. The marking detection device 11 is used to detect whether the reading rod 305 deflects to the other side of the assembly carrier 30 opposite to the initial position of the reading rod 305. The marking detection device 11 is communicatively connected to each working station. The reset device 12 is arranged on the other side of the carrier opposite to the initial position of the reading rod 305. The assembly carrier 30 passes through the reset device 12 only after passing through all the working stations. When the carrier passes through the reset device 12, the position of the reading rod 305 is restored; during assembly, the reading rod 305 is pushed to deflect to the specified side of the assembly carrier 30 to mark whether the workpiece on the carrier is qualified. The structure is simple and reliable, with high stability. By setting a simple optical head, it can be detected whether the slider deflects to one side, thereby determining whether the parts on the assembly carrier are qualified. When each working station detects a mark, the assembly carrier 30 is automatically skipped, so there is no need to pause the entire production line, and the efficiency is higher. A recycling device is arranged at the end of the conveying device 40, and the recycling device recycles the workpieces on the carrier.

[0055] As Figure 16 As shown in the figure, the rivet mechanism 13 includes a rivet carrier 131, a plurality of riveting machines 132 and a fixing machine 133.
