[0036] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] See also Figures 1 to 11 , is a key automatic assembly device according to an embodiment of the present invention, comprising a carrier assembly 10, a first positioning assembly 20 evenly spaced and installed on the carrier assembly 10, a second positioning assembly 30 installed above the first positioning assembly 20, and a power assembly 40 located on one side of the first positioning assembly 20. The first positioning assembly 20 is used to position the base 51, and the second positioning assembly 30 is used to position the key cap 52; the power assembly 40 is used to drive the first positioning assembly 20 to rotate, so that the first positioning assembly 20 and the second positioning assembly 30 rotate relative to each other, thereby realizing the automatic assembly of the base 51 and the key cap 52.

[0040] The carrier assembly 10 includes a bottom plate 11, a carrier frame 12 mounted on the bottom plate 11, and a plurality of sensors 13 evenly spaced and mounted on one side of the top surface of the carrier frame 12. The carrier frame 12 is evenly spaced along its length and is provided with a plurality of through holes 120, which are used to accommodate and install the first positioning assembly 20.

[0041] In this embodiment, the sensor 13 is a slot-type photoelectric switch for detecting the rotation of the first positioning component 20 .

[0042] The first positioning assembly 20 includes a bearing 21 mounted on the carrier 12, a suction nozzle 22 coaxially connected to the inner ring of the bearing 21, and a fixture 23 mounted on the top of the suction nozzle 22; the bearing 21 is correspondingly mounted inside the through hole 120, and the bottom end of the suction nozzle 22 is externally connected to the vacuum pump.

[0043] A boss 231 is protruding upward from the middle of the top surface of the fixture 23, and positioning pins 232 are connected to the opposite ends of the top surface of the boss 231. The boss 231 is provided with air extraction holes 233 on the inner side corresponding to each positioning pin 232, and the air extraction holes 233 penetrate the entire boss 231 and are connected to the suction nozzle 22 downward. The boss 231 and the positioning pin 232 are used to position the base 51, and the base 51 is used to cover the air extraction holes 233. The suction nozzle 22 can be used to vacuum the base 51 to achieve the positioning of the base 51. In actual use, it is also possible to judge whether the base 51 is placed on the fixture 23 by the air extraction state of the suction nozzle 22.

[0044] Furthermore, if Figure 4 and Figure 5 As shown, a rocker arm 24 is connected to one side of the bottom end of the nozzle 22, and the rocker arm 24 is used to connect the power assembly 40. A sensing sheet 25 is connected to one side of the top end of the nozzle 22, and the sensing sheet 25 corresponds to the sensor 13 one by one. Specifically, the sensing sheet 25 is used to pass through the notch of the sensor 13 to detect the rotation of the first positioning assembly 20.

[0045] The second positioning assembly 30 includes a support plate 31 connected to the carrier frame 12, and a positioning plate 32 connected to the top of the support plate 31; the positioning plate 32 is located above the fixture 23. The positioning plate 32 is evenly spaced along its length and has a plurality of through slots 33, which penetrate the positioning plate 32 and correspond to the fixture 23 one by one. The through slots 33 are used to position the key cap 52.

[0046] like Figures 7 and 8 As shown, supporting steps 34 are respectively protruded inwardly on the inner walls on the two opposite sides of the bottom of each through slot 33 , and arc-shaped limiting recesses 35 are respectively provided on the inner walls on the two opposite sides of the top of each through slot 33 corresponding to the upper sides of each supporting step 34 .

[0047] like Figures 9 to 11 As shown, the boss 231 and the positioning pin 232 extend into the middle of the through slot 33. The base 51 has protrusions 510 on opposite sides, and the protrusions 510 are located above the supporting step 34. The supporting step 34 is used to support the key cap 52, and the limiting recess 35 is used to limit the opposite ends of the key cap 52. The opposite ends of the key cap 52 are respectively provided with a card slot 520, and the card slot 520 is used to accommodate the corresponding protrusion 510. When assembling, as shown in FIG. Fig.10 and Fig.11 As shown, the power assembly 40 is used to drive the first positioning assembly 20 and the second positioning assembly 30 to rotate relative to each other, so that the base 51 and the keycap 52 rotate relative to each other, and the protrusion 510 rotates and embeds into the interior of the slot 520, automatically buckling the base 51 and the keycap 52 together to complete the assembly action.

[0048] The power assembly 40 includes a pushing element 41 located on one side of the carrier 12, and a resetting element 42 located on one side of the carrier 12; the pushing element 41 and the resetting element 42 are both used to connect the suction nozzle 22, wherein the pushing element 41 is used to drive the suction nozzle 22 to rotate, and the resetting element 42 is used to drive the suction nozzle 22 to reset after rotating.

[0049] In this embodiment, the pushing element 41 is a cylinder, which is connected to a push rod 411. A plurality of rollers 412 are evenly spacedly mounted on the push rod 411. The rollers 412 correspond to the rocker arms 24 one by one. The rollers 412 are used to abut against the rocker arms 24 to push the nozzle 22 to rotate.

[0050] In this embodiment, the reset element 42 is a tension spring, one end of the reset element 42 is connected to the bottom plate 11, and the other end of the reset element 42 is connected to the rocker arm. When the pushing element 41 retracts, the reset element 42 pulls the suction nozzle 22 to reset.

[0051] During actual operation, the pushing element 41 extends, pushing the suction nozzle 22 and the fixture 23 to rotate synchronously until the center line of the two positioning pins 232 coincides with the center line of the two limiting recesses 35. At this position, the base 51 is placed on the fixture 23 to ensure accurate positioning. Then, the pushing element 41 retracts, and the reset element 42 pulls the suction nozzle 22 and the fixture 23 to rotate in the opposite direction. At this time, the center line of the two positioning pins 232 is staggered with the center line of the two limiting recesses 35, making room for placing the keycap 52. The keycap 52 is placed between the two limiting recesses 35 to ensure that the card slot 520 of the keycap 52 is at the same horizontal position as the protrusion 510 of the base. Then, the pushing element 41 extends again, pushing the suction nozzle 22 and the fixture 23 to rotate synchronously. Since the keycap 52 is fixed, the base 51 rotates with the fixture 23, so that the protrusion 510 rotates and embeds into the inside of the card slot 520, achieving automatic buckling. Finally, the finished key is taken out. Repeat the above steps, put in a new base 51, and continue the next assembly cycle. Repeat this process to achieve the automatic assembly of the key.

[0052] The above-mentioned automatic key assembly device has a simple structure and is easy to use. The first positioning component 20 is used to position the base 51, and the second positioning component 30 is used to position the keycap 52. The power component 40 is used to drive the first positioning component 20 to rotate, and the first positioning component 20 and the second positioning component 30 rotate relative to each other, thereby realizing automatic assembly of the base 51 and the keycap 52, eliminating manual operation and greatly improving assembly efficiency and assembly quality.
