Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly of touch switches, in particular to a spring sheet adsorption and fixing structure on an automatic assembly line of a touch switch. Background Art

[0002] A touch switch is generally composed of a plastic base, a metal spring, a button and a cover. When automatically assembled with automated equipment, these materials are automatically loaded and assembled in sequence through an automatic loading mechanism. In production, the metal spring is very thin and light, and the loading process is greatly affected by external factors, making it relatively difficult to position it: a small shape and position tolerance of the upper limit hole groove on the mounting seat is not conducive to the smooth loading of the spring, affecting production efficiency; a large shape and position tolerance cannot guarantee the position accuracy of the spring on the plastic base, and the position accuracy of the spring directly affects the control sensitivity and feel of the touch switch. Therefore, how to ensure the position accuracy of the metal spring is the focus and difficulty of the automatic assembly line of the touch switch.

[0003] At present, in the assembly flow channel of the automatic machine of the touch switch, the bottom magnetic suction method is generally used to assist the positioning of the metal sheet. However, in some touch switch products with relatively thick plastic bases, such as base thickness exceeding 0.5mm, the conventional unidirectional magnetic suction has a weak restraining force on the metal sheet, making it difficult to ensure that each metal sheet maintains a high position accuracy.

[0004] Therefore, the utility model improves the positioning structure on the automatic assembly flow channel of this type of product to enhance its constraint on the metal sheet and improve the position accuracy of the metal sheet in the automatic assembly process. Utility Model Content

[0005] In response to the problems existing in the above-mentioned prior art, the utility model provides a spring clip adsorption and fixing structure on an automatic assembly line of a touch switch, which can adsorb a metal spring clip centrally on a product base, ensuring that the metal spring clip maintains a high position accuracy on the product base, thereby improving the assembly quality of the touch switch.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is as follows:

[0007] A spring sheet adsorption and fixing structure on an automatic assembly line of a touch switch is installed on an assembly track of an automatic feeding line, the assembly track is provided with one or more loading seats extending along its extension direction, each of the loading seats is provided with two rows of magnetic parts extending along its extension direction, the magnetism of each row of the magnetic parts on each loading seat is the same, and the magnetic poles of the two rows of the magnetic parts on each loading seat are opposite; a row of product bases can be matched and installed in each loading seat, and every two adjacent magnetic parts with opposite magnetism on each loading seat can adsorb a metal spring sheet in one of the product bases.

[0008] As a further elaboration of the above technical solution:

[0009] In the above technical solution, two parallel installation grooves are provided on the assembly rail along its extension direction, and a loading seat is matched and installed in each of the installation grooves.

[0010] In the above technical solution, each of the loading seats is a U-shaped structure, and two rows of holes are arranged on the inner bottom. Each of the holes is adapted to a magnetic part, and the depth of each hole is less than or equal to the height of each magnetic part.

[0011] In the above technical solution, an adjustment groove parallel to the loading seat is provided on one side of each loading seat on the assembly rail.

[0012] In the above technical solution, a plurality of avoidance grooves are also provided on the assembly track.

[0013] Compared with the prior art, the beneficial effects of the utility model are: by embedding a number of loading seats on the assembly track and embedding two rows of magnetic parts with opposite polarities on each loading seat, a row of product bases can be embedded on each loading seat, and a metal spring can be centrally adsorbed on a product base, and the product base and the metal spring can be limited and adsorbed from multiple directions to ensure that the metal spring maintains a high position accuracy on the product base, thereby improving the assembly quality of the touch switch; by setting the adjustment groove, the collision and wear between the product base and the assembly track during the assembly process can be reduced, the position accuracy of the product base can be improved, and then the adsorption and positioning accuracy of the magnetic parts on the metal spring can be improved; by setting the avoidance groove, avoidance space is provided for other sensing components or mechanism actions during the assembly process, which is easy to use.

[0020] like Figure 1-3As shown, a spring piece adsorption and fixing structure on an automatic assembly line of a touch switch is installed on an assembly track 1 of an automatic feeding line, and the assembly track 1 is provided with one or more loading seats 2 extending along its extension direction, and each of the loading seats 2 is provided with two rows of magnetic parts 3 extending along its extension direction, and the magnetic properties of each row of the magnetic parts 3 on each loading seat 2 are the same, and the magnetic poles of the two rows of the magnetic parts 3 on each loading seat 2 are opposite; each loading seat 2 can be matched with a row of product bases 10, and every two adjacent magnetic parts 3 with opposite magnetic properties on each loading seat 2 can adsorb a metal spring piece 20 in one of the product bases 10.

[0021] Specifically, two parallel installation grooves 101 are provided on the assembly rail 1 along its extension direction, and one of the loading seats 2 is matched and installed in each of the installation grooves 101 .

[0022] Specifically, each of the loading seats 2 is a U-shaped structure, and two rows of holes 201 are arranged on the inner bottom thereof. Each of the holes 201 is adapted to a magnetic component 3 , and the depth of each of the holes 201 is less than or equal to the height of each magnetic component 3 .

[0023] Specifically, an adjustment slot 4 parallel to each loading seat 2 is provided on one side of the assembly rail 1 .

[0024] like Figure 2 As shown, in this embodiment, an adjustment groove 4 is provided on the side of each loading seat 2, and a thinner cantilever structure is formed at the end of each loading seat 2, which can reduce the collision and wear when the loading seat 2 is installed into the assembly rail 1 and the product base 10 is installed into the loading seat 2, thereby ensuring the position accuracy between the magnetic part 3 and the product base 10, and assisting in improving the adsorption and positioning accuracy of the magnetic part 3 on the metal spring 20.

[0025] Furthermore, a plurality of avoidance grooves 5 are provided on the assembly track 1 .

[0026] like Figure 2 , 3 As shown, in this embodiment, avoidance grooves 5 are provided on the assembly track 1 and each loading seat 2 to provide avoidance space for other inductive components or mechanism actions during the assembly process, which is convenient to use.

[0027] like Figure 1As shown, before use, two rows of magnetic bodies 3 with opposite magnetic poles are first embedded in each loading seat 2, and then the loading seat 2 is embedded in the mounting groove 101 of the assembly track 1; when working, the loading mechanism first inserts the product base 10 into the U-shaped groove at the upper end of the loading seat 2 for positioning, and then another loading mechanism loads the metal spring pieces 20 in sequence from the top; each metal spring piece 20 is adsorbed in a product base 10 by the two magnetic parts 3 below, and at the same time, since the magnetic parts 3 at the lower end of each product base 10 have opposite magnetic attraction, the two magnetic parts 3 will attract each other and move closer to the center of the product base 10, and then the metal spring piece 20 will be adsorbed in the center position of the product base 10, thereby improving the relative position accuracy of the metal spring piece 20 and the product base 20.

[0028] During use, the depth and tilt angle of the hole 201 can be adjusted according to the specific structure of the product base 10 so that two magnetic members 3 with opposite magnetic attraction can adsorb a metal spring 20 at a proper position of the product base 10 .

[0029] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
