Problems solved by technology

At present, for the above-mentioned one-piece keyboard case, due to the lack of special devices, most of them manually assemble the middle plate, and then press down and assemble the key shafts one by one by the manipulator. However, the current operation will have the following problems: 1. The shaft usually has a key shaft housing and a trigger shaft body that moves up and down relative to the key shaft housing. In the process of assembling the key shaft, it is very easy to press down on the trigger shaft body, so it is easy to cause damage to the trigger shaft body
2. The PCBA board is installed on the middle board. During the process of inserting into the housing, manual operation will easily bring impurities into the housing and cover the trigger area on the PCBA board. In this way, it will affect the key shaft and the PCBA board. trigger fit

Embodiment 1

[0069] Such as Figure 1 to Figure 8 As shown, a feeder for key shafts, including a support base 1;

[0070] An upper positioning drive device is installed on the support base 1, and the output end of the upper positioning drive device is connected with a loading installation plate 2, and several feeding components are arranged on the loading installation plate 2;

[0071] The feeding assembly includes a feeding cylinder 3 and an upper adsorption member 7 detachably connected to the bottom of the feeding cylinder 3;

[0072] The feeding cylinder 3 has a feeding cavity, and the loading cylinder 3 is also provided with a sub-chamber plate 4, which divides the loading cavity into a loading and lower pressure chamber 5 and a lower pressure chamber located below the loading and lower pressure chamber 5. The feeding adsorption chamber 6, the sub-cavity plate 4 is provided with a plurality of sub-chamber communication ports 63 for connecting the feeding and lower pressure chamber 5 ...

Embodiment 2

[0081] This embodiment makes the following further limitations on the basis of Embodiment 1: the feeding assembly further includes a fixing rod 21 connected to the feeding installation plate 2, and an annular fixing groove 22 is opened on the outer surface of the fixing rod 21;

[0082] The feeding cylinder 3 also has a material feeding movable chamber located above the feeding cavity and sleeved on the fixed rod 21. The inner surface of the feeding movable chamber is provided with a ring that is inserted into the annular fixing groove 22 and can be connected with the annular ring. The fixed groove 22 moves up and down to match the annular movable ring 23;

[0083] The fixed rod 21 is also sleeved with an elastic member 24 of the upper material cylinder, and the elastic member 24 of the upper material cylinder acts on the annular movable ring 23, so that the annular movable ring 23 abuts against the bottom end of the annular fixed groove 22, and the active material feeding cavi...

Embodiment 3

[0089] This embodiment makes the following further limitations on the basis of Embodiment 1: the inner wall of the upper barrel 3 is also provided with a connecting assembly;

[0090] The connection assembly includes a connection support ring 25 located below the cavity plate 4 and a connection lock ring 26 between the cavity plate 4 and the connection support ring 25, the connection lock ring 26 can be opposite to the upper barrel 3 turn;

[0091] The middle part of the connecting support ring 25 has an insertion port 27, and the middle part of the connecting locking ring 26 has a locking port 28 with a non-circular section;

[0092] A rotating bar-shaped opening 29 is provided on the side wall of the upper barrel 3, and a locking handle 30 extending through the rotating bar-shaped opening 29 and capable of moving relative to the rotating bar-shaped opening 29 is extended on the connecting locking ring 26;

[0093] The outer surface of the upper end of the upper adsorption m...

Abstract

The invention discloses a feeder for a key shaft and an assembly mechanism with the feeder. The feeder comprises a supporting base; an upper positioning driving device is mounted on the supporting base, the output end of the upper positioning driving device is connected with a feeding mounting plate, and a plurality of feeding assemblies are arranged on the feeding mounting plate; the feeding assemblies comprise feeding cylinders and upper adsorption parts detachably connected to the bottom ends of the feeding cylinders; and the feeding cylinders are provided with air blowing connecting holescommunicating with feeding pressing cavities and positioned above pressing cylinders, and the feeding cylinders are also provided with air suction connecting holes communicating with feeding adsorption cavities. According to the feeder for the key shaft and the assembly mechanism with the feeder, through the arrangement of the feeding cylinders and the upper adsorption parts, not only can the maximum adsorption coverage range be achieved when the key shaft is transferred so as to ensure the adsorption stability, but also the function coverage range can be effectively reduced when the key shaftis assembled so as to protect a trigger shaft body from being impacted by airflow.

Description

technical field [0001] The invention relates to the technical field of keyboards, in particular to a feeder for key shafts and an assembly mechanism with the feeder. Background technique [0002] As an input tool, the keyboard is usually used in conjunction with a computer, and it has become an indispensable electronic product in people's daily life. Most of the existing keyboards include a shell, a middle plate with a PCBA board installed, a key shaft and a key cap assembled on the key shaft, and the shell is mostly composed of a lower cover and an upper cover detachably connected to the lower cover. During assembly, the middle plate is usually assembled on the lower cover first, and then the upper cover is assembled on the middle plate and fixedly connected with the lower cover. [0003] Since the separate design of the upper cover and the lower cover will complicate the components, some manufacturers have designed the shell as an integrated structure, such as Figure 12 ...
