The terms used in the specification of this invention are only for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0041] As Figures 1 - 3 shown, the overall structure of the tactile switch includes: a leaf spring 01, a base 02 with a metal terminal 03, a cover 04 and a button 05. In some embodiments, they form a first combination 1 according to the combination of the leaf spring 01 and the base 02, the cover 04 and the button 05 form a second combination 2, then the two combinations are combined to form a semi-finished product 3, and finally, through hot pressing and riveting, Figure 4 the finished tactile switch shown is formed.

[0042] In some embodiments, a single-layer tactile switch automatic assembly machine is provided, which includes a frame 300 and a turntable mechanism 100 installed on the frame 300. The turntable mechanism 100 includes a turntable 101 and a fixed seat 102 disposed in the middle of the turntable 101. A number of carriers 103 are arranged at intervals on the turntable mechanism. A product slot 1030 is provided on the carrier 103. A base feeding mechanism 10 for feeding the base 02 into the product slot 1030 of the carrier, a leaf spring feeding mechanism 20 for feeding the leaf spring 01 into the product slot 1030 of the carrier, a sub-assembly mechanism 200 for feeding the second combination 2 of the button 05 and the cover 04 into the product slot 1030 of the carrier, and a general assembly mechanism 50 for hot pressing and riveting the first combination 1 and the second combination 2, that is, hot pressing and riveting between the cover 04 and the base 02, are installed on the frame 300. The base feeding mechanism 10, the leaf spring feeding mechanism 20, the sub-assembly mechanism 200 and the general assembly mechanism 50 are distributed in sequence along the turntable mechanism 100 corresponding to their respective workstations.

[0043] The base feeding mechanism 10 of a single-layer tactile switch automatic assembly machine is as Figures 7 - 9As shown, the base feeding mechanism 10 includes a base circular vibratory bowl 11, a base linear feeder 12, a base linear vibrator 13, and a base loading component 14. The base loading component 14 has a receiving plate 141, a first movable bearing 142, and a base loading cylinder 140. A receiving groove 1410 is provided on the receiving plate 141. The receiving groove 1410 is docked with the discharge port of the base linear feeder 12, and a through product dropping hole 1411 is provided in the direction of the product groove 1030 on the receiving groove 1410. The first movable bearing 142 is located between the product dropping hole 1411 and the product groove 1030, and has a product dropping channel 1420 for dropping the product (i.e., the base 02) in the product dropping hole 1411 into the product groove 1030. The movable end of the base loading cylinder 140 is provided with a base actuator 143 for driving the displacement of the first movable bearing 142, so that the product dropping channel 1420 corresponds to the product dropping hole 1411 and the product groove 1030 one by one.

[0044] In some embodiments, the base actuator 143 may include a push plate 1430 and a base actuating block 1431. The push plate 1430 is connected to the movable rod of the base loading cylinder 140. An installation groove for installing the base actuating block 1431 is provided on the push plate 1430, so that the base actuating block 1431 can be disassembled and replaced, improving the convenience during use. Specifically, as Figure 10 shown, the base actuating block 1431 has a connecting portion 14310 connecting to the installation groove, and a vertical portion 14311 and an inclined portion 14312 that cooperate with the first movable bearing 142. It can be understood that the base 02 in the base circular vibratory bowl 11 is sent to the receiving groove 1410 and the product dropping hole 1411 according to a preset orientation through the base linear feeder 12. When the carrier 103 reaches the base loading station, the base loading cylinder 140 is activated to drive the push plate 1430 and the base actuating block 1431 to move downward. During the downward movement, the base actuating block 1431 contacts the first movable bearing 142 and causes the first movable bearing 142 to move horizontally until the transition from the inclined portion 14312 to the vertical portion 14311. At this time, the channels of the product dropping channel 1420, the product dropping hole 1411, and the product groove 1030 are opened, and the base 02 falls into the bottom of the product groove 1030 through this channel, completing the loading of the base 02. In some embodiments, a plurality of sets of loading channels can be set at one time, enabling the loading of several bases 02 at one station to improve the operation efficiency.

[0045] As shown in Figure 10 the figure, the shrapnel feeding mechanism 20 of a single-layer tactile switch automatic assembly machine includes a shrapnel pulling mechanism 21 for pulling the tape, a shrapnel cutting mechanism 22 for cutting the tape, and a step conversion mechanism 23 for changing the feeding pitch of the shrapnel 01.

[0046] The sub - packaging mechanism 200 of a single - layer tactile switch automatic assembly machine is as follows Figures 11 - 14 shown. The sub - packaging mechanism 200 includes a lid feeding mechanism 40 for feeding the lid 04 to the first position of the combination station, a button feeding mechanism 30 for feeding the button 05 to the second position of the combination station, a pick - up mechanism that sucks up the lid 04 and the button 05 respectively at the first and second positions of the combination station, and that sucks up the lid 04 and the button 05 at the first and second positions of the combination station to form a second combination 2 and sends the second combination 2 into the carrier product slot 1030.

[0047] The pick - up mechanism includes a combined cylinder 70. The combined cylinder has a first combined cylinder 71, a second combined cylinder 72, and a third combined cylinder 73. A pick - up part 80 is arranged at the driving end of the combined cylinder 70, as Figure 3 , Figure 6 , Figure 21 shown. A transfer groove 801 is arranged on the pick - up part 80. A convex column 802 is arranged on the transfer groove 801. Air holes 803 for sucking the lid 04 and the button 05 are respectively arranged on the transfer groove 801 and the convex column 802. The pick - up part 80 is respectively controlled by the first combined cylinder 71, the second combined cylinder 72, and the third combined cylinder 73. In some embodiments, the pick - up part 80 can be a vacuum suction head.

[0048] In some embodiments, the lid feeding mechanism 40 includes a lid circular vibrator 41, a lid linear feeder 42, a lid linear vibrator 43, and a lid dispensing cylinder 44. A dispensing plate 45 is connected to the push rod of the lid dispensing cylinder 44. A convex platform 450 extends upward from the end of the dispensing plate 45. A dispensing groove 4501 connecting to the discharge port of the lid linear feeder 42 is arranged on the convex platform 450. Under the action of the linear vibrator, the lid 04 falls into the dispensing groove 4501, and then is conveyed to the first position of the combination station, that is: directly below the pick - up part 80, by the drive of the lid dispensing cylinder 44. Then, under the action of the first combined cylinder 71, the pick - up part 80 moves downward to make the transfer groove 801 cooperate with the lid 04 to suck up the lid 04, and then the dispensing plate 25 retreats.

[0049] In some embodiments, the button feeding mechanism 30 includes a button circular vibrator 31, a button linear feeder 32, a button linear vibrator 33, and a button sorting cylinder 34; among them, the process of feeding the button 05 to the combination station is basically the same as the process of conveying the lid 04, which will not be repeated here. When the button 05 is conveyed to the combination station, that is: when the button 05 is conveyed to the exact lower end of the picking part 80, the picking part 80 is controlled by the second combination cylinder 72. Under the drive of the second combination cylinder 72, the convex column 802 on the picking part 80 cooperates with the button 05 to suck the button 05 and move it to a certain position so that the lid 04 and the button 05 are combined to form the second combination 2. Finally, under the action of the third combination cylinder 73, the second combination 2 is conveyed to the product slot 1030 of the carrier to complete the assembly; it should be noted that the convex column 802 extends out of the mounting hole 401 (see Figure 14 and 15 ) of the lid 04 to pick up the material.

[0050] The general assembly mechanism 50 of a single-layer tactile switch automatic assembly machine is as shown in Figures 16 - 17 . The general assembly mechanism 50 is for the assembly of the first combination 1 and the second combination 2, that is, for riveting between the lid 04 and the base 02. The general assembly mechanism 50 includes a riveting cylinder 51 and a hot pressing die core 52 connected to the output shaft of the riveting cylinder 51. After the carrier 103 is in place for this process, under the drive of the riveting cylinder 51, the hot pressing die core 52 descends for hot pressing and riveting, and finally enters the next station.

[0051] The discharging mechanism 60 of a single-layer tactile switch automatic assembly machine is as shown in Figures 18 - 20 . The discharging mechanism 60 is arranged on the frame 300 and is used to move the assembled tactile switch finished product out of the carrier 103. Specifically, the discharging mechanism 60 includes a discharging cylinder 61 and a movable plate 62 connected to the driving end of the discharging cylinder 61. An ejection punch 63 and an actuating block 64 are arranged on the movable plate 62. A carrier 103 and a discharge port 1010 are arranged on the rotary table 101. A second movable bearing 104 is arranged on the carrier 103. The second movable bearing 104 passes through the inside of the carrier 103 and has a discharging channel for dropping the product in the product slot 1030 out of the discharge port 1010; that is, when the carrier 103 reaches the discharging station, the discharging cylinder 61 is started, and its actuating block 64 pushes the second movable bearing 104 to displace horizontally, so that the discharging channel corresponds to the product slot 1030 and the discharge port 1010 one by one. When pushing down further, the ejection punch 63 pushes the finished product in the product slot 1030 out of the discharge port 1010.

[0052] In some embodiments, the discharging mechanism 60 further has a guiding mechanism 65 and a collection box 66. The guiding mechanism 65 is connected to the discharging port 1010, and the collection box 66 is connected to the guiding mechanism 65 to centrally collect the assembled tactile switch finished products.

[0053] In some embodiments, the structure of the actuating block 64 is the same as that of the base actuating block 1431.

[0054] Compared with the prior art, the automatic assembly machine of the present application uses a turntable divided into two parts for assembly, with high utilization rate of each spare part, good stability, high qualification rate and high production efficiency of the assembled products, and is simple to operate and convenient to maintain.

[0055] The technical invention is not limited to the above embodiments, and as long as the solutions mentioned in the specification fall within the protection scope of the present invention.

[0056] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art of the present invention, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
