Description

Technical Field

[0001] The utility model relates to the technical field of silica gel keypads, in particular to a high-efficiency silica gel keypad cutting device. Background Art

[0002] Silicone keys are one of the many keys of electronic products. Its main function is to achieve a conductive key through the conductive black substance of the glue. When the silicone key is pressed, the conductive rubber under the key can be electrically connected with the contact below. When the silicone key is released, the conductive rubber under the key bounces up and is not connected with the contact below, thereby achieving the effect of conduction and disconnection. Therefore, it is widely used in electronic calculators, remote controls, telephones, cordless phones, electronic toys, computer keyboards, learning machine keys, cipher keys, and digital product keys.

[0003] At present, the molding process of silicone buttons mainly involves injecting the prepared silicone raw material in liquid form into the molding mold, and evenly filling the silicone raw material into each cavity of the mold by extrusion or compression, and then demolding after cooling and solidification to obtain a whole page of silicone button products. Subsequently, in order to obtain a single silicone button, the molded whole page of silicone button products needs to be cut and trimmed.

[0004] As described in the published patent "A Silicone Button Quick and Accurate Cutting Structure" with announcement number CN211466596U, simple tools are commonly used for positioning and art blades are used for manual rough cutting. However, this cutting method is relatively primitive and cannot cut the silicone button in the middle. It is easy to cut it crookedly, which can easily cause work injuries. In addition, the cutting efficiency is low. Only one silicone button product can be cut at a time. There is no guarantee for accurate size measurement in the later stage, which reduces efficiency.

[0005] In summary, the current slitting of the entire page of key products after molding requires manual slitting with a blade one by one, which is time-consuming and labor-intensive, resulting in low slitting efficiency. In addition, the manual slitting process also has the disadvantage of low cutting accuracy, resulting in a high defect rate and easy occurrence of work-related injuries.

[0006] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution that can solve the problems of manual slitting, which is time-consuming, labor-intensive, low-efficiency, and low cutting precision resulting in a high defect rate.

[0008] To achieve the above object, the utility model provides the following technical solutions: An efficient slicing device for silicone buttons, comprising a positioning jig for positioning the product parts to be sliced, a transverse cutting assembly, and a vertical cutting assembly. Multiple transverse cutting grooves and vertical cutting grooves are formed on the positioning jig, and positioning blocks corresponding to individual product parts are formed at the intersections of the transverse cutting grooves and the vertical cutting grooves on the positioning jig;

[0009] The transverse cutting assembly includes a first bottom plate, a transverse cutting plate is arranged on the first bottom plate, first slide rails are installed on the front and rear sides of the upper end of the first bottom plate, both sides of the transverse cutting plate are slidably connected with the first slide rails in a matching manner, and a first cutting knife corresponding to the transverse cutting groove is installed at the lower end of the transverse cutting plate;

[0015] As a further scheme of the utility model: Two first limit columns are arranged at the four corners of the first bottom plate, the two first limit columns are respectively located on both sides of the first slide rail, and the first limit columns are screwed to the first bottom plate;

[0016] Two second limit columns are arranged at the four corners of the second bottom plate, the two second limit columns are respectively located on both sides of the second slide rail, and the second limit columns are screwed to the second bottom plate.
