Technical Field

[0001] The invention relates to the technical field of silicone product processing equipment, and in particular to a silicone key switch post-lamination vacuum baking equipment. Background Art

[0002] Silica gel is a highly active adsorption material and an amorphous substance. It does not react with any substance except strong alkali and hydrofluoric acid, is insoluble in water and any solvent, is non-toxic and odorless, and has stable chemical properties. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.

[0032] Specifically, before putting the silicone into the device, after releasing the lock of the contactless unlocking module 9 on the mounting plate 10, the spring 1 803 will push the slide bar 802 out of the slide rail 801. During the movement of the slide bar 802, the curved plate 1 805 connected to the slide bar 802 will compress the strip groove 804 so that the air in the strip groove 804 is transported into the air bag 2 811 through the air duct 812.

[0035] Specifically, when it is necessary to place the silica gel on the uniformly heated module 7, lightly step on the pedal 910 with your foot. After the pedal 910 rotates and contacts the pressure plate 907, it presses the locking plate 902 connected to the narrow groove 901 to move downward in the narrow groove 901, so that the locking plate 902 releases the lock on the mounting plate 10, so that the mounting plate 10 can be moved out of the box body 1. After placing the silica gel, lightly push the mounting plate 10 to push the mounting plate 10 into the box body 1. Under the push of the spring 2 906, the locking plate 902 re-enters the slot 903 to lock the mounting plate 10.

[0036] In specific application scenarios, the contactless unlocking module 9 is mainly suitable for the contactless unlocking link in the contactless unlocking process, that is, the contactless unlocking module 9 uses the pedal 910 and the locking plate 902 to enable the operator to complete the operation without direct contact with the high-temperature objects in the device when the silicone needs to be removed after the silicone is baked, thereby avoiding the risk of burns to personnel and improving safety.

[0037] The working principle of the present invention is as follows: before starting the vacuum baking, open the box door 2, and lightly step on the pedal 910 with your foot. The pedal 910 rotates and contacts the pressing plate 907, and then presses the locking plate 902 connected to the narrow groove 901 to move downward in the narrow groove 901, so that the locking plate 902 releases the lock on the mounting plate 10, so that the mounting plate 10 can be moved out of the box body 1. After placing the silica gel on 705, lightly push the mounting plate 10 to push the mounting plate 10 into the box body 1. Under the push of the spring 2 906, the locking plate 902 re-enters the locking groove 903 to lock the mounting plate 10. During the movement of 10, spring 1 803 will push the slide bar 802 out of the slide rail 801. During the movement of the slide bar 802, the curved plate 1 805 connected to the slide bar 802 will compress the strip groove 804 so that the air in the strip groove 804 is transported into the air bag 2 811 through the air guide tube 812. The knob 815 is turned so that the knob 815 can move on the fixed interface 814, so that the fixed interface 814 tightens or loosens the control of the cross-sectional area of ​​the air guide tube 812, thereby changing the air delivery amount, so that the slide bar 802 can slide out of the slide rail 801 at a uniform speed, and the start The driving motor 715 drives the gear 2 725 meshing with the gear 1 716 to rotate, so that the belt 721 drives the rotating roller 720 to rotate, and the rotating roller 720 drives the steering wheel 722 and the connecting rod 723 on the movable shaft 719 to rotate. The upper limit rod 724 of the connecting rod 723 is bound by the side groove 713 when rotating, so that the limit rod 724 pushes the inner wall of the side groove 713 to make the star-shaped member 711 drive the support plate 701 to rotate. When the limit rod 724 moves to the curved corner on the central groove 712, the steering wheel 722 will contact the curved corner of the contact member 714. The edge is fitted and the base plate 701 stops rotating as the limiting rod 724 rotates from the curved corner to the straight edge, so that the silicone on the tray 705 is heated for a period of time. After the limiting rod 724 turns the curved corner and moves to the edge groove 713 of the straight edge, the base plate 701 will continue to rotate a quarter of the circumference, and so on. The rotating base plate 701 drives the main gear 709 to engage and rotate with the slave gear 706, so that the slave gear 706 rotates the same circumference in the process of engaging with the rack 707, so that different parts of the silicone on the tray 705 can be baked.
