Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a switch button welding device comprises a jig 1, an objective lens 2, a plastic film 3, a switch contact point 4 and a plastic button 5, wherein a through hole 11 is formed in the middle of the jig 1, the objective lens 2 is fixedly installed in the through hole 11, the plastic film 3 is arranged between the objective lens 2 and the plastic button 5, a groove 51 is formed in one side, adjacent to the plastic film 3, of the plastic button 5, the switch contact point 4 is placed in the groove 51, the jig 1 does up-and-down reciprocating motion under the action of external force, and the jig 1 drives the plastic film 3 to abut against the plastic button 5. Specifically, in this embodiment, when plastic button 5 passes through from objective 2 below, tool 1 begins to move, and specifically, can use cylinder or pneumatic cylinder drive tool 1 to do up-and-down reciprocating motion, drives tool 1 and is close to plastic button 5. When objective 2 promoted plastic film 3 and the limit portion butt of plastic button 5, laser emitter (not shown in the figure) began the motion, and the laser that jets out passes through objective 2 after, pierces through plastic film 3, melts the limit portion of plastic button 5, and then is integrative with plastic film 3 and plastic button 5 welding. When needing to explain, switch contact 4 is directly placed in the recess 51 of plastic button 5, consequently, in order to prevent switch contact 4 displacement in welding process, this technical scheme uses cylinder drive tool 1 moving as a whole, and displacement plastic button 5 is moved from top to bottom, avoids switch contact 4 to receive the displacement of shaking. According to the technical scheme, the penetrating type welding process of the plastic button 5 and the plastic film 3 is realized, the plastic film 3 is pressed on the plastic button 5 through the objective lens 2 capable of moving up and down, the surface of the welding position of the plastic film 3 and the plastic button 5 is smooth, the welding is firm, and the plastic film is not easy to fall off.

As shown in fig. 1-2, a blind hole 21 is formed on one side of the objective lens 2 adjacent to the plastic button 5. In particular, in the present embodiment, the blind hole 21 is used for accommodating the switch contact 4, and collision of the surface of the objective lens 2 with the switch contact 4 is avoided.

As shown in fig. 1-2, a convex edge 22 is disposed on one side of the objective lens 2 away from the plastic button 5, and the convex edge 22 is connected with the inner baffle 12 at the end of the jig 1. Specifically, objective 2 is cylindricly, is provided with chimb 22 at objective 2 limit portion, utilizes chimb 22 cooperation internal baffle 12 card main objective 2, prevents that objective 2 is not hard up when following the upper and lower displacement of tool 1.

As shown in fig. 1-2, a protrusion 31 is disposed on the plastic film 3 corresponding to the switch contact point. Specifically, the protrusion 31 is arranged on the plastic film 3, and the switch contact point 4 is covered by the protrusion 31, so that the plastic film 3 is prevented from being punctured by the switch contact point 4 when the plastic film 4 is pressed down along with the objective lens 2.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
