Description

Technical Field

[0001] The invention is applied to the technical field of product assembly, and in particular relates to a balancing seat assembly device. Background Art

[0002] At present, the space bar, enter key and other keys on the mechanical keyboard are too long, so they need to use a balance seat. The balance seat is an auxiliary structure that can make the keycap pressed smoothly. The keycap installed on the balance seat can avoid the problem of the keycap tilting left and right during typing, ensuring that the user can trigger the key by tapping any position of the keycap.

[0003] The balancing seat includes a balancing shaft, two seat cores and two bases. The balancing shaft includes a transverse shaft and two plug-in shafts. The two plug-in shafts are arranged in parallel on the transverse shaft. During the assembly process of the balancing seat, the two seat cores are first assembled into the mounting holes of the two bases respectively, and then the two plug-in shafts of the balancing shaft are respectively inserted into the two plug holes of the bases, and finally the transverse shaft of the balancing shaft is pressed to position the transverse shaft in the clamping hole of the base, thereby completing the entire assembly process. However, the traditional assembly method is all carried out manually, which has high labor intensity and low work efficiency. It is not suitable for mass production in factories, is prone to fatigue, cannot guarantee the assembly quality of the balancing seat, and has low reliability.

[0004] There is a patent with publication number CN206194592U that provides a keyboard key balance bar assembly machine and a keyboard key balance bar and key cap assembly machine with compact structure, convenient disassembly and assembly, easy production, safety and reliability, and strong practicality. Although the assembly machine has high production efficiency, saves manpower, and overcomes the randomness of manual assembly, the balance bar is not oiled before being assembled on the keyboard aluminum plate, and the smoothness of the key cap pressing cannot be guaranteed, which easily leads to the problem of key jamming. If a balance seat assembly device with high automation and smooth key cap pressing can be designed, the above problems can be well solved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a balance seat assembly device which has a high degree of automation and can ensure smooth keycap pressing.

[0006] The technical solution adopted by the present invention is: the present invention includes an axle seat loading mechanism, a balancing shaft loading mechanism, a balancing seat unloading mechanism, a first turntable mechanism, a second turntable mechanism, an oiling mechanism and a shaft inserting mechanism. The axle seat loading mechanism loads the axle seat onto the first turntable mechanism, the balancing shaft loading mechanism loads the balancing shaft onto the second turntable mechanism, the oiling mechanism oils the balancing shaft, the shaft inserting mechanism assembles the balancing shaft after oiling onto the axle seat, and the balancing seat unloading mechanism unloads the assembled balancing seat.

[0007] It can be seen from the above scheme that the shaft seat feeding mechanism loads the shaft seat onto the first turntable mechanism, and the first turntable mechanism drives the shaft seat to the shaft insertion station under the intermittent rotation action of the first turntable mechanism, and the balancing shaft feeding mechanism loads the balancing shaft onto the second turntable mechanism, and the second turntable mechanism drives the balancing shaft to the oiling station under the intermittent rotation action of the second turntable mechanism, and the oiling mechanism first oils the balancing shaft, and then drives the oiled balancing shaft to the shaft insertion station under the rotation of the second turntable mechanism, and the shaft insertion mechanism assembles the oiled balancing shaft to the shaft seat, and finally, under the rotation of the first turntable mechanism again, drives the assembled balancing seat to the unloading station, and the balancing seat unloading mechanism unloads the assembled balancing seat, and the cycle is repeated in sequence. Under the intermittent rotation action of the first turntable mechanism and the second turntable mechanism, the balancing shaft and the shaft seat are continuously loaded, and then the balancing shaft is assembled on the shaft seat, and finally the assembled balancing seat is unloaded. Therefore, the present invention realizes the automatic assembly of the balance seat, greatly improves the assembly efficiency of the balance seat, avoids the problem of manual assembly errors, and after the balance shaft is oiled, the balance shaft is assembled to the shaft seat, which ensures that the keycap can be pressed smoothly after being assembled on the balance seat, avoids the problem of key jamming, and greatly improves the reliability, which is suitable for large-scale production in factories.
