Description

Technical Field

[0001] The utility model relates to the technical field of key assembly production, in particular to a five-way key pressing device. Background Art

[0002] In the prior art, the key plate and key cap of the five-way key are assembled by manual pressing, and the current operation method cannot ensure that the key cap is pressed with a force in a vertical direction. Summary of the invention

[0003] The utility model aims to overcome the deficiencies of the prior art and provide a five-way key pressing device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A five-way key pressing device comprises a machine table, a jig plate and a pressing plate, wherein the jig plate is fixed on the table top of the machine table, and a plurality of assembly positions arranged at intervals are arranged on the jig plate, and each assembly position comprises a key cap positioning groove arranged at the bottom and a key plate positioning groove arranged above the key cap positioning groove; the pressing plate is located directly above the jig plate and is driven to rise and fall by a cylinder fixed above the machine table; three vertically arranged pressing rods are fixed to the bottom of the pressing plate corresponding to each assembly position, one of the pressing rods is arranged corresponding to the center of the key cap positioning groove, and the other two pressing rods are arranged corresponding to the two ends of the key plate positioning groove.

[0006] Furthermore, the four top corners of the bottom of the pressing plate are respectively provided with guide columns arranged vertically, and the four top corners of the top of the fixture plate are respectively provided with guide sleeves slidably matched with the corresponding guide columns.

[0007] Furthermore, two sides of the keypad positioning groove are respectively provided with clearance grooves for taking and placing the keypad.

[0008] Furthermore, a plurality of assembly positions are arranged in a matrix on the fixture plate.

[0009] The utility model adopts the above technical solution, and has the following beneficial effects:

[0010] 1. Use a jig plate to pre-position the key cap and key plate. When the pressing plate is pressed down, the edges of both ends of the key plate and the center of the key cap are simultaneously stressed vertically. The cylinder presses to ensure that the pressure on the key plate remains constant each time it is pressed, thereby effectively improving the reliability of the assembly of the key cap and key plate;

[0011] 2. Use the pressure rod to accurately press the center of the button cap to achieve uniform and stable force. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0013] Figure 1 It is an overall schematic diagram of the utility model;

[0014] Figure 2 Schematic diagram of the jig plate and the pressing plate. DETAILED DESCRIPTION

[0015] like Figure 1-2 As shown, the five-way key pressing device of the utility model includes a machine table 1, a jig plate 2 and a pressing plate 3. The jig plate 2 is fixed on the table top of the machine table 1. The jig plate 2 is provided with a plurality of assembly positions arranged at intervals. Preferably, the plurality of assembly positions are arranged in a matrix on the jig plate 2. Each assembly position includes a key cap positioning groove 4 arranged at the bottom and a key board positioning groove 5 arranged above the key cap positioning groove 4. The two sides of the key board positioning groove 5 are respectively provided with a clearance groove 6 for taking and placing the key board. The pressing plate 3 is located directly above the jig plate 2 and is driven to rise and fall by a cylinder fixed above the machine table 1. Three vertically arranged pressing rods 7 are respectively fixed to the bottom of the pressing plate 3 corresponding to each assembly position, one of the pressing rods 7 is arranged corresponding to the center of the key cap positioning groove 4, and the other two pressing rods 7 are respectively arranged at the two ends of the key board positioning groove 5.

[0016] In order to achieve stable downward pressing of the pressing plate 3 in the direction perpendicular to the plate surface, a guide structure is provided between the pressing plate 3 and the jig plate 2. The specific structure is as follows: vertically arranged guide columns 31 are respectively provided at the four top corners of the bottom of the pressing plate 3, and guide sleeves 21 that slide with the corresponding guide columns 31 are respectively provided at the four top corners of the top of the jig plate 2.

[0017] The working principle of the utility model is as follows: first, a key cap and a key plate are placed in each assembly position, and then the cylinder drives the pressing plate 3 to press down, and the three pressing rods 7 corresponding to each assembly position are pressed down synchronously, so that the edges at both ends of the key plate and the center of the key cap are simultaneously subjected to vertical force, and the cylinder pressing is realized to ensure that the pressure on the key plate is kept constant each time it is pressed, thereby effectively improving the stability of the assembly. Moreover, the center of the key cap is accurately pressed by the pressing rod 7 in the middle, so that the force is uniform and stable.

[0018] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
