Problems solved by technology

The assembly of the keycaps is generally achieved by pressing. If the position of the balance bar and the shaft bracket is not accurate, or the shaft bracket is not in the pop-up state, the installation of the keycap will be defective, such as the buckle on the keycap is deformed or damaged. The ribs on the cap become white due to stress deformation, which affects the strength and appearance

Embodiment

[0022] Please refer to Figure 1-Figure 3 , the present embodiment is a tooling structure 4 for keyboard assembly, which includes a bearing base plate 41 and a pressing plate 42 for flattening the base plate, and the base plate 41 is provided with a base plate receiving groove 43 . The substrate receiving groove 43 is provided with an installation auxiliary mechanism for limiting the installation of the balance bar and the keycap of the special function key. A magnetic block 431 , an elastic thimble 432 for pushing up the rotating shaft bracket in the base plate, a limiting block 433 for limiting the end of the balance bar, and a pressure supporting block 436 for supporting the rotating shaft bracket.

[0023] The limiting block 433 is provided with a limiting groove 434 that limits the depth of the end of the balance bar inserted into the mounting buckle of the substrate.

[0024] The first magnetic block 431 is arranged along the balance bar, which can ensure that the balan...

Abstract

The invention discloses a tooling structure for keyboard assembly, including a bearing base plate, A pressure plate which flattens the substrate, A substrate receive groove is arranged on that load-bearing bottom plate, the base plate receiving groove is provided with a mounting auxiliary mechanism for limiting the mounting of a balance bar and a key cap of a special function key, The mounting auxiliary mechanism comprises a first magnetic block embedded in the bearing bottom plate and attracting the balance bar downward, an elastic ejector pin lifting the rotating shaft bracket in the base plate upward, and a limiting clip block for limiting the position of the end of the balance bar. The invention can precisely limit the end of the balance bar and ensure that the key cap can be loaded smoothly.

Description

【Technical field】 [0001] The invention belongs to the technical field of assembly line tooling, in particular to a tooling structure for keyboard assembly. 【Background technique】 [0002] The keyboard is an indispensable part of computer equipment. The keyboard includes a circuit board, an elastic pressing head arranged on the circuit board, a shaft bracket, and a keycap. There is also a balance bar to ensure the balance of the keycap when the key is pressed. Due to the complex key structure of the keyboard, the installation method of the balance bar and the keycap becomes particularly important. The special function button area on the circuit board will be provided with mounting buckles for hanging on both ends of the balance bar. The openings in the mounting buckle are generally After the end of the balance bar is inserted into the bar-shaped opening, it can move forward, backward, left, and right. There are some buckles on the inner surface of the keycap that hold the ba...
