Description

Technical Field

[0001] The present invention relates to the field of production devices for tactile switches, and particularly to an automated production device for leveling, detecting, and taping tactile switches. Background Art

[0002] Tactile switches are widely used due to their small size, convenient and flexible operation, etc. There is a huge demand for tactile switches in the market. Although semi-automatic or fully automatic assembly production of tactile switches has been realized, most tactile switch manufacturers use sampling inspection to control quality. Inevitably, there will be omissions. The sampling inspection results only have reference value and cannot fully and truly reflect the actual production situation of the products. Moreover, during the sampling inspection process, the products need to be transferred through multiple processes, consuming a large amount of time and manpower. Therefore, a device capable of online automated detection of tactile switch products is needed to meet the product quality inspection requirements. To meet the above needs, we propose an automated production device for leveling, detecting, and taping tactile switches. Summary of the Invention

[0011] Preferably, a pressing plate is provided at the end of the piston rod of the second pushing cylinder, and first elastic pieces are symmetrically arranged on both sides of the pressing plate. One ends of the two groups of first elastic pieces are both provided with first wiring terminals.

[0012] Preferably, the insulation detection mechanism is provided with a third pushing cylinder, a third material blocking cylinder and a third photoelectric on the side of the slide rail. Both the third pushing cylinder and the third material blocking cylinder are perpendicular to the side wall of the slide rail.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figures 1 - 8 , an automatic production device for flattening and testing braiding of a touch switch, comprising a vibration plate 1 for feeding the touch switch and a baler 9 for packaging the touch switch, a slide rail 2 is connected between the discharge port of the vibration plate 1 and the feed port of the baler 9, a flattening mechanism 3, a function detection mechanism 4, an insulation detection mechanism 5 and a CCD visual detection mechanism 6 are sequentially arranged along the slide rail 2, and a blowing mechanism 7 for rejecting defective products is arranged between the function detection mechanism 4 and the insulation detection mechanism 5, between the insulation detection mechanism 5 and the CCD visual detection mechanism 6, and between the CCD visual detection mechanism 6 and the baler 9, the flattening mechanism 3, a function detection mechanism 4, an insulation detection mechanism 5 and a CCD visual detection mechanism 6 are arranged between the insulation detection mechanism 5 and the CCD visual detection mechanism 6, and between the CCD visual detection mechanism 6 and the baler 9. The mechanism 3, the function detection mechanism 4 and the insulation detection mechanism 5 are all cylinder combination structures. A slide groove 201 is provided at the top of the slide rail 2 along its length direction. The device connects the discharge port of the vibration plate 1 and the feed port of the baler 9 through the slide rail 2, and integrates the leveling mechanism 3, the function detection mechanism 4, the insulation detection mechanism 5, the CCD visual detection mechanism 6 and the blowing mechanism 7 along the slide rail 2. The equipment structure is simple and clear, and it can realize automatic pin leveling, function detection and insulation detection of the finished micro switches produced, and remove defective products through CCD visual inspection re-inspection, which effectively improves the detection efficiency of the micro switches.

[0033] The leveling mechanism 3 is provided with a first pushing cylinder 301, a braking cylinder 304, a first material blocking cylinder 305 and a first photoelectric sensor 306 on one side of the slide rail 2. The first pushing cylinder 301, the braking cylinder 304 and the first material blocking cylinder 305 are all perpendicular to the side wall of the slide rail 2. The braking cylinder 304 and the first material blocking cylinder 305 are distributed on both sides of the first pushing cylinder 301. The end of the piston rod of the first pushing cylinder 301 is provided with an inner support plate 302. The top of the inner support plate 302 is provided with a finger cylinder 303. The clamping blocks of the finger cylinder 303 are distributed on both sides of the inner support plate 302 with a gap left therebetween.

[0034] As Figure 3 and Figure 4 shown, the microswitch is pushed forward by the airflow ejected from the feeding air pipe 8. When the first photoelectric sensor 306 detects the microswitch, the braking cylinder 304 and the first material blocking cylinder 305 eject. The microswitch at the front end is blocked by the piston rod of the first material blocking cylinder 305. The first pushing cylinder 301 pushes the inner support plate 302 to insert between the two pins of the microswitch. The clamping blocks of the finger cylinder 303 act to clamp the pins once. The pins are flattened by the clamping blocks of the finger cylinder 303 and the inner support plate 302. After completion, except for the braking cylinder 304, other cylinders return to the zero position. The microswitch with flattened pins is pushed into the function detection mechanism 4 by the airflow. When the second photoelectric sensor 406 detects the pins, the braking cylinder 304 releases, and the above process is repeated.

[0035] As Figure 5 shown, the function detection mechanism 4 is provided with a second pushing cylinder 401, a second material blocking cylinder 405 and a second photoelectric sensor 406 on the side of the slide rail 2. The second pushing cylinder 401 and the second material blocking cylinder 405 are both perpendicular to the side wall of the slide rail 2. The function detection mechanism 4 is vertically provided with a trigger cylinder 407 at the bottom end of the slide rail 2. The end of the piston rod of the second pushing cylinder 401 is provided with a pressing plate 402. The two sides of the pressing plate 402 are symmetrically provided with first elastic pieces 403. One ends of the two groups of first elastic pieces 403 are both provided with first connection terminals 404.

[0036] After the second photoelectric sensor 406 detects the microswitch, the piston rod of the second material blocking cylinder 405 extends to block the microswitch. The second pushing cylinder 401 pushes out the pressing plate 402 and the first elastic pieces 403. Here, the detection circuit in the electrical cabinet needs to be connected to the first connection terminal 404 through a cable. The first elastic piece 403 contacts the pins of the microswitch. The piston rod of the trigger cylinder 407 pushes up the button part of the microswitch to trigger the opening or closing of the microswitch once, providing detection conditions for the detection circuit of the electrical cabinet. After the detection is completed, the second material blocking cylinder 405 retracts, enabling the microswitch to enter the insulation detection mechanism 5.

[0037] AsFigure 6 As shown, the insulation detection mechanism 5 is provided with a third pushing cylinder 501, a third material blocking cylinder 505 and a third photoelectric sensor 506 on the side of the slide rail 2. The third pushing cylinder 501 and the third material blocking cylinder 505 are both perpendicular to the side wall of the slide rail 2. The end of the piston rod of the third pushing cylinder 501 is provided with two groups of partition plates 504. A pressing piece 502 is arranged between the partition plates 504. Second elastic pieces 503 are arranged on both sides of the partition plates 504 away from each other. Second connection terminals 507 and third connection terminals 508 are respectively arranged at one ends of the second elastic piece 503 and the pressing piece 502;

[0038] The insulation detection mechanism 5 of this device is similar to the function detection mechanism 4. The difference is that the resistance value between the pin of the microswitch and the housing is detected through the second elastic piece 503 and the pressing piece 502 to judge the insulation safety of the microswitch.

[0039] As Figure 7 , Figure 8 As shown, the CCD vision detection mechanism 6 is provided with a bracket 601 on one side of the slide rail 2. The top of the bracket 601 is provided with a CCD camera 602. The blowing mechanism 7 includes a main air pipe 701. The top of the main air pipe 701 is communicated with the chute 201. A branch pipe 702 is arranged on one side of the main air pipe 701. The top of the branch pipe 702 is provided with a side blowing pipe 703. The side blowing pipe 703 is U-shaped. A feeding blowing air pipe 8 is arranged on one side of the slide rail 2. The feeding blowing air pipe 8 is distributed along the length direction of the slide rail 2;

[0040] The basic working principle of CCD vision detection is to pre-store the external shape photos of qualified microswitches, and then take pictures of the products online through the CCD camera 602 for identification. If the similarity is lower than the safety value, it is judged as unqualified, otherwise it is qualified;

[0041] The above-mentioned function detection mechanism 4, insulation detection mechanism 5 and CCD vision detection mechanism 6 are all equipped with a blowing mechanism 7. The unqualified microswitches are blown up through the upward main air pipe 701, and the unqualified microswitches are blown away from the slide rail 2 through the side blowing pipe 703.

[0042] Working principle: The microswitch is pushed forward by the airflow ejected from the feeding air pipe 8 of the vibrating bowl 1. When the first photoelectric sensor 306 detects the microswitch, the brake cylinder 304 and the first material blocking cylinder 305 eject. The microswitch at the front end is blocked by the piston rod of the first material blocking cylinder 305. The first pushing cylinder 301 pushes the inner support plate 302 to insert between the two pins of the microswitch. The clamping block of the finger cylinder 303 acts to clamp the pins once, and the pins are flattened by the clamping block of the finger cylinder 303 and the inner support plate 302. After completion, except for the brake cylinder 304, other cylinders return to the zero position. The microswitch with flattened pins is pushed into the function detection mechanism 4 by the airflow. When the second photoelectric sensor 406 detects the pins, the brake cylinder 304 releases. The piston rod of the second material blocking cylinder 405 extends to block the microswitch. The second pushing cylinder 401 pushes out the pressing plate 402 and the first elastic sheet 403. Here, the detection circuit in the electrical cabinet needs to be connected to the first terminal 404 through a cable. The first elastic sheet 403 contacts the pins of the microswitch, and the piston rod of the trigger cylinder 407 pushes up the button part of the microswitch to trigger the opening or closing of the microswitch once, providing detection conditions for the detection circuit of the electrical cabinet. After the detection is completed, the second material blocking cylinder 405 retracts, causing the microswitch to enter the insulation detection mechanism 5. The insulation detection mechanism 5 of this device is similar to the function detection mechanism 4, detecting the feeding through the third photoelectric sensor 506 and triggering the detection action. The difference is that the resistance value between the pins and the housing of the microswitch is detected through the second elastic sheet 503 and the pressing piece 502 to judge the insulation safety of the microswitch. Subsequently, the microswitch enters the CCD vision detection mechanism 6. Its basic working principle is to pre-store the external shape photos of qualified microswitches, and then the product is photographed and recognized online by the CCD camera 602. If the similarity is lower than the safety value, it is judged as unqualified, otherwise it is qualified. The function detection mechanism 4, the insulation detection mechanism 5, and the CCD vision detection mechanism 6 are all equipped with blowing mechanisms 7. The unqualified microswitches are blown up by the main air pipe 701 upward, and the unqualified microswitches are blown off the slide rail 2 by the side blowing pipe 703, so that the qualified microswitches finally fall into the packing machine 9 for packing.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
