Description

Technical Field

[0001] This utility model relates to the field of metal spring technology, and specifically to a metal spring assembly tool. Background Technology

[0002] Metal springs are an important electronic component used in switch buttons. Based on the elastic properties of metal springs, when subjected to external force, the center point of the metal spring will be concave, forming a circuit with the circuit on the circuit board, allowing current to pass through. When the external force is removed, the metal spring quickly returns to its original shape, waiting for the next press.

[0003] After the metal springs are mass-produced, they are guided by vibration and placed on a platform in a certain arrangement. Then, they are placed into the slots of buttons or switches using magnetic adsorption or clamping. The springs are then assembled through a connecting positioning mechanism. In common cases, clamping requires specially designed clamps with specific shapes and sizes, which is relatively troublesome. Therefore, magnetic adsorption is commonly used, with a structure at the magnetic end that fits the metal spring to ensure stable adsorption. However, the direction of magnetic adsorption is uncontrollable, which can cause the metal spring to deviate from the structure at the magnetic end, affecting the assembly efficiency of the metal springs.

[0004] According to Chinese Patent Publication No. CN218836694U, "A Metal Spring Assembly Tool", the main feature described is the use of a limiting device. When stamping the metal spring and spring, the limiting device can fix the position of the metal spring and spring, thereby ensuring that the connection point of the metal spring and spring will not be misaligned. This is beneficial for the stamping of the connection point by the stamping rod, and for accurately assembling the metal spring and spring together, thus improving the success rate of the assembly of the metal spring and spring. However, using magnetic adsorption will cause relative offset between the metal spring and the connecting structure on the magnetic end, thereby reducing the assembly efficiency of the metal spring.

[0005] Therefore, a metal spring assembly tool is proposed to solve the problem that the metal spring and the connection structure of the magnetic end will be relatively offset when using magnetic adsorption, which will reduce the assembly efficiency of the metal spring. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the connection structure between the metal spring and the magnetic end will be relatively offset when using magnetic adsorption, which will reduce the assembly efficiency of the metal spring. Therefore, a metal spring assembly tool is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is as follows: a metal spring assembly tool, including an operating table and a storage slot. A limiting slot is opened on one side of the operating table. A first motor is fixedly connected to the operating table on one side of the limiting slot. A first screw is fixedly connected to the output end of the first motor. A slider is threadedly connected to the first screw. A second motor is fixedly connected to the bottom side of the slider. A turntable is fixedly connected to the output end of the second motor. A bracket is fixedly connected to one side of the upper end of the turntable. A support plate is fixedly connected to the upper end of the bracket. A third motor is fixedly connected to one side of the upper end of the support plate. A second screw is fixedly connected to the output end of the third motor. A moving platform is threadedly connected to the second screw. A metal rod is fixedly connected to one end of the moving platform. A connecting plate is fixedly connected to one end of the metal rod. A metal plate is in contact with the bottom side of the connecting plate. A pressure groove is opened on the bottom side of the metal plate. A coil is in contact with the metal rod. A power source is fixedly connected to both ends of the coil. The power source is fixedly connected to the moving platform. A spring slot is opened on one side of the operating table.

[0008] As a preferred technical solution of this utility model, the operating table is fixedly connected to a bracket on one side of the spring slot, and a vertical plate is fixedly connected to one end of the bracket. A fourth motor is fixedly connected to one side of the vertical plate, and a third screw is fixedly connected to the output end of the fourth motor. A contact plate is threaded onto the third screw, and a pressing block is fixedly connected to one side of the contact plate. The pressing block corresponds to the spring slot. By setting the fourth motor to drive the third screw to rotate, the contact plate and the pressing block can be moved, so that the pressing block contacts the spring slot and pushes the spring body to the accurate position.

[0009] As a preferred technical solution of this utility model, the operating table has an extension groove in the spring slot. A displacement sensor is fixedly connected in the extension groove. The displacement sensor is connected to a controller via a wire. The controller is fixedly connected to the power supply side. A spring rod is fixedly connected in the extension groove. A pad is fixedly connected to the upper end of the spring rod. The upper side of the pad is flush with the upper side of the spring slot and has the same structure. By setting the displacement sensor in the extension groove, it will transmit an electrical signal to the controller when it receives sufficient pressure, thereby causing the metal rod and coil to have electromagnetic function, thereby generating adsorption.

[0010] As a preferred technical solution of this utility model, a pressure rod is fixedly connected to the center of the bottom end of the pad. The pressure rod corresponds to the position of the displacement sensor. By setting the pressure rod, the displacement sensor can be accurately positioned, thereby improving the accuracy of signal transmission.

[0011] As a preferred technical solution of this utility model, a positioning rod is threadedly connected to the metal plate, and the positioning rod is inserted into the connecting plate. By setting the positioning rod, the metal plate can be easily disassembled and replaced, thereby adapting to metal plates with different structures.

[0012] This utility model has the following advantages: by setting a movable stage that can rotate and adjust the height, the metal plate is driven into the spring slot and the storage slot. Then, the metal plate squeezes the pad, causing the displacement sensor to transmit an electrical signal to the controller. The electrical signal causes the metal plate to magnetically attract the metal spring, thereby installing the metal spring in the switch, thus improving the assembly efficiency and assembly accuracy.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-3The illustrated metal spring assembly tool includes an operating table 1 and a storage slot 2. A switch or button is placed into the storage slot 2. A limit groove 3 is formed on one side of the operating table 1. A first motor is fixedly connected to the operating table 1 on one side of the limit groove 3. The first motor drives a first screw 4 to rotate, allowing a slider 5 to move within the limit groove 3. The output end of the first motor is fixedly connected to the first screw 4, and the slider 5 is threaded onto the first screw 4. A second motor is fixedly connected to the bottom side of the slider 5. The second motor can drive a turntable 6 to rotate, allowing adjustment of the angle of a moving platform 9. The output end of the second motor is fixedly connected to the turntable 6. A bracket is fixedly connected to one side of the upper end of the turntable 6. A support plate 7 is fixedly connected to the upper end of the bracket. A third motor is fixedly connected to one side of the upper end of the support plate 7. The third motor drives a second screw 8 to rotate, allowing the height of the moving platform 9 to change. The output end of the third motor is fixedly connected to the turntable 6. A second screw 8 is fixedly connected, and a movable platform 9 is threaded onto the second screw 8. A metal rod 10 is fixedly connected to one end of the movable platform 9, and a connecting plate 11 is fixedly connected to one end of the metal rod 10. A metal plate 12 is in contact with the bottom side of the connecting plate 11, and a coil 15 is in contact with the metal rod 10. A power supply 14 is fixedly connected to both ends of the coil 15 and is fixedly connected to the movable platform 9. A spring slot 16 is provided on one side of the operating table 1. The positive and negative terminals of the power supply 14 are connected to the coil 15. At the same time, the coil 15 is wound around the metal rod 10. A resistor is set on one side of the power supply 14, and the resistor is connected in series with the coil 15. The power supply 14 supplies power through the coil 15, generating a magnetic field that makes the metal rod 10, the connecting plate 11, and the metal plate 12 magnetic. When the metal plate 12 contacts the metal spring (the metal spring is not shown in the figure, but is located in the spring slot 16), an adsorption effect is generated.

[0020] The spring slot 16 corresponds to the extrusion block 25. The extrusion block 25 is fixedly connected to one side of the contact plate 24. A third screw 22 is threaded onto the contact plate 24. The third screw 22 is fixedly connected to the output end of the fourth motor. The fourth motor is fixedly connected to one side of the vertical plate 23. A bracket is fixedly connected to the vertical plate 23. The bracket is fixedly connected to one side of the operating table 1 and is close to the operating table 1. By setting the fourth motor to drive the third screw 22 to rotate, the contact plate 24 and the extrusion block 25 can be made to enter the spring slot 16, thereby extruding the side of the metal spring and accurately positioning the position of the metal spring.

[0021] The pad 19 is fixedly connected to the upper end of the spring rod 18, which is fixedly connected to the extension groove 17. The controller is fixedly connected to the power supply 14, and the controller is connected to the displacement sensor 21 through a wire. The displacement sensor 21 is fixedly connected to the extension groove 17, which is located on the bottom side of the spring plate groove 16 and on the side of the operating table 1. The upper side of the pad 19 is flush with the upper side of the spring plate groove 16 and has the same structure. When the pad 19 is squeezed, it will move down and squeeze the displacement sensor 21. Then the displacement sensor 21 transmits a signal to the controller on the power supply 14 side. The controller controls the power supply 14 to transmit power through the coil 15, which then causes the metal rod 10 to generate magnetic force and transmits it synchronously to the connecting plate 11 and the metal plate 12, thereby generating magnetic force to attract and attract the metal spring plate.

[0022] The positions of the displacement sensor 21 and the pressure rod 20 can also be changed. The pressure rod 20 is fixedly connected to the center of the bottom end of the pad 19. By setting the pressure rod 20, the displacement path is reduced, making the signal transmission more efficient.

[0023] The connecting plate 11 is fitted with a positioning rod 13, which is threaded onto the metal plate 12. By setting the positioning rod 13, it is easy to disassemble and replace metal plates 12 of different specifications.

[0024] Working principle: The switch or button is placed into the storage slot 2, and the metal spring is placed into the spring slot 16. The fourth motor drives the contact plate 24 and the pressing block 25 to move into the spring slot 16, pressing the metal spring so that it gradually rests on the pad 19. Then, through the cooperation of the first screw 4 and the second screw 8, the metal plate 12 aligns with the metal spring. At this time, the second screw 8 rotates, causing the moving platform 9 to move downwards. Then, the metal plate 12 presses the metal spring and transmits force to the pad 19, causing the spring rod 18 on the bottom side of the pad 19 to retract. At this time, the pressure rod 20 contacts the displacement sensor 21, and the displacement sensor 21 transmits an electrical signal to the controller under force. The controller controls the power supply 14 to transmit power to the coil 15, and then the current passes through the coil 15, making the metal rod 10 magnetic, and simultaneously conducting it to the connecting plate 11 and the metal plate 12, so that the metal plate 12 has an adsorption effect, and then adsorbs the metal spring piece. Subsequently, through the action of the first screw 4 and the second screw 8, the metal spring piece on the bottom side of the metal plate 12 is pressed into the switch or button in the storage slot 2. At this time, the power supply 14 stops supplying power.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
