[0002] The keyboard base plate is inside the keyboard used to install the switches that correspond to the keys. Made of metal, it is stamped using a stamping machine. Due to its thinness, residual stress remains after stamping, affecting its physical properties and lifespan. Furthermore, the stamped base plate may have some curvature; an uneven plate can prevent the switches from being installed or cause poor contact between the keys and switches. Therefore, it is necessary to reshape the stamped keyboard base plate to eliminate residual stress and ensure its flatness.

However, it is difficult to control the pressure on the keyboard base plate, and it is easy to apply too much or too little pressure, resulting in poor alignment effect. In addition, the edges and corners of the keyboard base plate are easily damaged during the pressure application. Its practical performance needs to be improved. Therefore, it is necessary to provide a keyboard base plate alignment device to solve the above technical problems. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0020] Example 1: As Figures 1-4As shown, this utility model provides a keyboard base plate calibration device, comprising: a calibration unit, the calibration unit including: a pair of cavity plates 1, the cavity plates 1 being made of stainless steel, possessing excellent strength and excellent thermal conductivity; a material cavity 2 being provided between the pair of cavity plates 1; and heat-conducting oil 3 being provided inside the cavity plates 1. The heat-conducting oil 3 is a synthetic heat-conducting oil, specifically T66 from Solutia International, USA, with an operating temperature reaching 345℃. Of course, the heat-conducting oil 3 can also be other types of heat-conducting oil, the specific type of heat-conducting oil 3 is not specifically limited, as long as it meets the usage requirements; and a high-temperature resistant valve structure and a high-temperature resistant pressure relief valve structure are provided on the rear surface of the cavity plates 1, the former being used to inject the heat-conducting oil 3 into the cavity plates 1. The latter not only prevents overpressure damage to equipment but also reduces the risk of fire, meeting safety regulations. Furthermore, the outlet of the pressure relief valve is fitted with a high-temperature resistant hose structure, the other end of which is connected to the high-temperature resistant container, providing a flow guiding effect during pressure relief. A heat insulation layer 4 is fixedly fitted onto the outer side of the cavity plate 1. The heat insulation layer 4 is a ceramic heat insulation plate, which can effectively slow down heat loss to the outside. A metal plate 5 is connected to the side of the heat insulation layer 4 away from the cavity plate 1. The metal plate 5 is a low-carbon steel plate (such as Q235 or A3 steel) with a coating (such as a zinc coating), possessing high magnetic permeability, easy magnetization, and high magnetic attraction strength. A substrate 6 is provided on the side of the metal plate 5 away from the heat insulation layer 4, and the inner wall of the substrate 6 is... An electromagnet 7 is included. The outer wall of the electromagnet 7's casing is fitted with a base plate 6 with a clearance. The power cord of the electromagnet 7 is connected to an external power supply device to provide the electrical energy required for its operation. The working principle of the electromagnet 7 is that a conductive winding is wound around the outside of an iron core. When current passes through the coil, a magnetic field is generated around the coil, thus forming an electromagnet. The electromagnet can attract magnetic materials. The electromagnet 7 is attracted and connected to the metal plate 5. A mounting plate 8 is fixed to one side of the electromagnet 7. First bolts 9 are inserted into the four corners of the mounting plate 8. The first bolts 9 pass through the mounting plate 8 and are threadedly connected to the base plate 6. Connectors 10 are fixed to the four corners of the side of the base plate 6 away from the metal plate 5. Multiple connectors 10 fixed to the two base plates 6 are used to connect the two base plates 6. The heat insulation layer 4 is fixedly installed on the surface of the external fixed workbench and the output end of the telescopic device. Handles 11 are fixed on both sides of the heat insulation layer 4. The handles 11 make it easy for the operator to apply force to the heat insulation layer 4 and provide some convenience when disassembling and replacing it. Electric heating rods 12 are provided on both sides of the inside of the material cavity 2. The electric heating rods 12 are connected to the cavity plate 1. The power cord of the electric heating rods 12 is connected to the external power supply device, which can provide the required power for the operation of the electric heating rods 12. The electric heating rods 12 convert electrical energy into heat energy through the Joule heating effect (resistance heating). Its core structure is a resistance wire (heating element). When current passes through, the resistance wire generates heat due to resistance and transfers the heat to the surrounding medium (such as water, oil, etc.) through thermal conduction.

[0021] Example 2: The electromagnet 7 is located at the center of the substrate 6. The center points of the electromagnet 7 and the metal plate 5 are both located on the same horizontal and vertical line. This arrangement allows the attraction force generated by the electromagnet 7 on the metal plate 5 to act evenly on the metal plate 5 during operation.

[0022] Example 3: The metal plate 5 is connected to the heat insulation layer 4 through a connecting unit. The connecting unit includes multiple vertical slots 13, which are respectively opened at the four corners of the side of the metal plate 5 facing the substrate 6. A second bolt 14 is inserted into the bottom of the inside of the vertical slot 13. A threaded cylinder 15 is threadedly connected to the outer wall of the second bolt 14. The threaded cylinder 15 is fixedly connected to the heat insulation layer 4. A rod 16 is provided inside the vertical slot 13. The rod 16 is fixedly connected to the substrate 6. Two rods 16 are respectively inserted into the inside of two vertical slots 13. Due to the insertion relationship between the rods 16 and the vertical slots 13, the metal plate 5 and the cavity plate 1 can be quickly aligned and installed with the substrate 6.

[0023] Example 4: Multiple balls 17 are slidably engaged on the outer wall of the insertion rod 16. The balls 17 are in contact with the inner wall of the vertical groove 13. The balls 17 can roll, but cannot be separated from the insertion rod 16, which can reduce the frictional resistance between the insertion rod 16 and the inner wall of the vertical groove 13.

[0024] Example 5: The end of the insertion rod 16 away from the substrate 6 is tapered, which makes it easier for the insertion rod 16 to be inserted into the vertical groove 13 more quickly.

[0025] In use, firstly, the two base plates 6 need to be fixed to the surface of the external fixed workbench and the output end of the telescopic device respectively through the connector 10. Then, the cavity plate 1 needs to be installed between the base plates 6, and the metal plate 5 needs to be attached to the surface of the heat insulation layer 4. Next, the second bolt 14 is threaded to the threaded cylinder 15, and then the metal plate 5 can be attached to the base plate 6. During this process, the two insert rods 16 need to be inserted into the two vertical slots 13 respectively. Due to the insertion relationship between the insert rods 16 and the vertical slots 13, the metal plate 5 and the cavity plate 1 can be quickly aligned and installed with the base plate 6. At this time, the electromagnet 7 is activated to fully attract and position the metal plate 5, and the installation between the cavity plate 1 and the base plate 6 is completed. Then, the keyboard base plate to be shaped can be placed between the two cavity plates 1. The external telescopic device is driven to make the two cavity plates 1 fit together. During this process, the inner wall of the material cavity 2 will fully fit with the keyboard base plate. At this time, while maintaining the applied pressure, the heating rod 12 is powered. After the heating rod 12 is powered, it can be evenly transferred to the inner wall of the material cavity 2 through the heat transfer oil 3, which can heat the keyboard base plate in the pressed state. During this process, the keyboard base plate to be shaped is heated to the tempering temperature. Combined with the flattening force of the inner wall of the material cavity 2 on the keyboard base plate, the keyboard base plate can be shaped relatively quickly and with high quality. The keyboard base plate will not be damaged during the shaping process. In addition, the user can control whether the electromagnet 7 is running to control whether the base plate 6 is connected to the metal plate 5. The cavity plates 1 can be disassembled and replaced relatively quickly, and the cavity plates 1 of different shapes of material cavities 2 can be replaced more conveniently and quickly.

[0026] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
