It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0038] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1 As shown, a silicone keyboard surface screen printing device provided by an embodiment of the utility model, the silicone keyboard surface screen printing device comprises:

[0040] Shell 1;

[0041] A conveying mechanism, mounted on the housing 1, for conveying the silicone keyboard;

[0042] A lifting mechanism is arranged in the housing 1, a lifting platform 2 is arranged on the lifting mechanism, and a support rod 21 is arranged on the lifting platform 2;

[0043] The screen printing mechanism is arranged on the support rod 21, and the support rod 21 is arranged across the conveying mechanism so that the conveying mechanism is between the lifting platform 2 and the screen printing mechanism;

[0044] A driving motor 22 is arranged on the lifting platform 2;

[0045] A gear rod 23 is provided on the lifting platform 2. A first driving gear 24 is provided at one end of the gear rod 23, and a second driving gear 25 is provided at the other end. The gear rod 23 can rotate under the drive of the driving motor 22.

[0046] The first transmission mechanism is connected to the first driving gear 24 and the transmission mechanism. The driving motor 22 drives the gear rod 23 to rotate, so that the first driving gear 24 rotates, and then the transmission mechanism is operated through the first transmission mechanism.

[0047] The second transmission mechanism is connected to the screen printing mechanism. When the lifting mechanism drives the lifting platform 2 to descend, the first driving gear 24 is separated from the first transmission mechanism to stop the transmission mechanism. The second driving gear 25 is connected to the second transmission mechanism to operate the screen printing mechanism to perform screen printing on the silicone keyboard on the transmission mechanism. After the screen printing is completed, the lifting mechanism drives the lifting platform 2 to rise, the second driving gear 25 is separated from the second transmission mechanism to stop the screen printing mechanism, and the first driving gear 24 is reconnected to the first transmission mechanism to operate the transmission mechanism.

[0048] In this embodiment, the housing 1 includes a main housing 1 and a sub-housing 1.

[0049] In this embodiment, a plurality of support rods 21 may be provided on the lifting platform 2, and each support rod 21 jointly lifts the screen printing mechanism to form an arch bridge structure, and the transmission mechanism is in the "arch" of the arch bridge structure; the first transmission mechanism includes a first transmission gear 3, and in the initial state, the first drive gear 24 is meshed with the first transmission gear 3, and under the drive of the drive motor 22 and the transmission of the gear rod 23, the first drive gear 24 and the first transmission gear 3, the transmission mechanism moves to transmit the silicone keyboard, and due to the lifting of the support rods 21, the screen printing mechanism and the transmission mechanism are separated by a certain distance, so that the silicone keyboard can move smoothly on the transmission mechanism without being hindered; when the silicone keyboard moves to the bottom of the screen printing mechanism, the user can adjust the lifting mechanism to lower the lifting platform 2, thereby making the first transmission gear 3 and the second transmission gear 3 move downward. A driving gear 24 is separated from the first transmission mechanism, causing the transmission mechanism to stop running. At the same time, the second driving gear 25 is connected to the second transmission mechanism to operate the screen printing mechanism to screen print the silicone keyboard on the transmission mechanism. After the screen printing is completed, the lifting mechanism drives the lifting platform 2 to rise, and the second driving gear 25 is separated from the second transmission mechanism to stop the screen printing mechanism. The first driving gear 24 is reconnected with the first transmission mechanism to operate the transmission mechanism; in the present application, through the coordinated cooperation of the first transmission mechanism and the second transmission mechanism, it can be ensured that when the screen printing mechanism is working, the transmission mechanism stops moving in coordination. After the screen printing mechanism stops working, the transmission mechanism randomly transmits, that is, the screen printing mechanism and the transmission mechanism work in coordination, which avoids the silicone keyboard being removed before the screen printing is completed, thereby ensuring the quality of the product.
