Description

Technical Field

[0001] This utility model relates to the field of screw machine technology, and more specifically, to a fastening module. Background Technology

[0002] In the process of fastening screws, there are usually two feeding methods: adsorption or blow-and-suction. Adsorption requires the screw to be adsorbed into the suction tube, while blow-and-suction uses compressed air to blow the screw into the clamp, and then the suction tube is extended to adsorb the screw for fastening. However, the blow-and-suction feeding method is not suitable for screws with a head diameter ratio of less than 1.2 (i.e., screws with large heads and short screw lengths). Therefore, screws with a head diameter ratio of less than 1.2 can only be fastened by adsorption: after the arranging machine feeds the screws, the robot moves to the picking point to adsorb and fasten them, and then repeats this cycle. However, this traditional fastening method greatly delays production efficiency, wastes time, and causes the production rhythm to fall behind, affecting the performance. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example

[0035] Reference Figures 1-6 This utility model provides a technical solution: a screw fastening module, including a base plate 1, a storage track mechanism 3, and a screw fastening mechanism 14. A hollow hopper 2 is installed on the upper surface of the base plate 1. The storage track mechanism 3 includes a conveying track 31, which is installed on the base plate 1. A limit plate 311 is installed above the conveying track 31. A matching storage track 312 is fixedly installed at one end of the conveying track 31. A sliding gate 32 is installed at one end of the storage track 312 to limit the screw. A first air pressure plate 33 is installed on the conveying track 31 to move the screw quickly and arrange it neatly. The screw fastening mechanism 14 includes a precision guide rail 141, which is set outside the sliding gate 32. A servo motor 1411 is set on the precision guide rail 141, and a screw fastening cylinder 1412 is installed outside the servo motor 1411. A screw suction cylinder 142 is installed at the telescopic end of the screw fastening cylinder 1412 to suction the screw.

[0036] The locking mechanism 14 in this device also includes a module base plate, on which a set of precision guide rails are mounted. The guide rails include two independent sliders that move along the Y-axis. A servo motor is mounted on the upper slider for tightening and loosening bolts, and a fixing plate and a vacuum suction tube 15 are mounted on the lower slider for adsorbing screws, facilitating their movement above the hole for anti-air locking. A set of combined cylinders is also provided, with the longer-stroke locking cylinder 1412 and the shorter-stroke screw-adsorbing cylinder 142 connected by a retractable spring bushing. The upper slider is fixedly connected to the locking cylinder 1412 via a fixing plate, which acts as a buffer. The suction cylinder 142 is fixed on the fixing plate below the base plate. A special guide copper sleeve is installed at the lower end of the servo motor. The vacuum suction tube passes through the guide copper sleeve and plays a role in fixing concentricity. When the locking cylinder 1412 drives the upper slider and the servo motor to press down, the vacuum suction tube extends out of the guide copper sleeve and engages with the tail of the screw to tighten and lock. A material storage track 312 is also installed below the module base plate and is stably connected to the module base plate via a fixing plate.

[0037] In a preferred embodiment, a roller 4 is installed inside the hollow chamber 2, and a motor 13 is installed outside the roller 4. The motor 13 drives the roller 4 to rotate. One end of the conveying track 31 is located inside the roller 4 for feeding screws. A hopper 5 is also provided inside the hollow chamber 2 for storing screws. In order to facilitate the movement of screws onto the conveying track 31, the device has a roller 4 installed inside the hollow chamber 2 and drives the roller 4 through the motor 13 to control the rotation of the roller 4. As the roller 4 rotates continuously, the screws will be wound into the inside of the roller 4 so that the screws can be moved inside the conveying track 31.

[0038] In a preferred embodiment, a vibrating seat 6 is fixedly installed inside the hollow hopper 2. The vibrating seat 6 is stably connected to the conveying track 31. This device conveys screws to the storage track 312. In order to ensure that the screws move in an orderly and stable manner on the storage track 312, a vibrating seat 6 is installed inside the hollow hopper 2. The vibrating seat 6 will vibrate the screws, so that the screws can move in a stable and orderly manner.

[0039] The hollow hopper 2 is also equipped with a screening brush 7, which is set above the conveying track 31 to remove excess screws and most screws with abnormal postures on the conveying track 31. A connecting plate 8 is fixedly installed on the outside of the storage track 312. A second air pressure plate 9 is stably installed on one side of the connecting plate 8. A full material detector 10 is installed at one end of the storage track 312. A cylinder 11 is installed on the outside of the storage track 312 to control the number of screws blown each time.

[0040] In actual use, screws are fed onto the storage track 312. Since the length of the storage track 312 is limited, it will eventually be filled with screws. In order to detect in time that the storage track 312 is full of screws, a full material detector 10 is set to detect the screws on the storage track 312, thereby stopping the roller 4 from rotating in time and stopping the feeding of screws onto the storage track 312.

[0041] An origin sensor 12 is fixedly installed on the outside of the storage track 312. A connecting block is installed on the outside of the sliding gate 32, with one end of the connecting block positioned inside the origin sensor 12 to detect the opening and closing of the gate. When the storage track 312 is full of screws, a sliding gate 32 is installed at one end of the storage track 312 to prevent the screws from falling off. The sliding gate 32 limits the screws and prevents them from falling off the storage track 312. When the screws are taken out, the sliding gate 32 can be pressed to move. After the sliding gate 32 is released, it will automatically return to its initial position to continue limiting the screws, which is convenient for use.

[0042] Specifically, the working process or principle of a screw fastening module is as follows: In the screw fastening process, there are usually two feeding methods: adsorption or blow-and-suction. Adsorption requires adsorbing the screw into the suction tube, while blow-and-suction uses compressed air to blow the screw into the clamp and then extends the suction tube to adsorb the screw for fastening. However, the blow-and-suction feeding method is not suitable for screws with a head diameter ratio of less than 1.2 (i.e., screws with large heads and short screw lengths). Therefore, screws with a head diameter ratio of less than 1.2 can only be fastened by adsorption: after the arranging machine feeds the screws, the robot moves to the picking point to adsorb and fasten them, and then repeats this cycle. However, this traditional fastening method greatly delays production efficiency, wastes time, and causes the production rhythm to fall behind, affecting the performance. Therefore, this device was designed to solve this problem.

[0043] This device can automatically and orderly convey screws in a certain form to ensure stable conveying. When the screws are conveyed to the end position, they can be directly taken out for use. The specific operation is as follows: connect an external power source, load screws into the hollow hopper 2 in batches, and put them into the hopper 5. Drive the roller 4 to rotate through the motor 13. As the roller 4 rotates continuously, the screws will be rolled into the roller 4. The rotation of the roller 4 will move the screws into the conveying track 31. Under the action of the first air pressure plate 33, the screws will be blown and moved on the conveying track 31.

[0044] The first air-blowing pressure plate 33 in this device uses compressed air as power to make the screws in the conveying track 31 move quickly and arrange neatly, thereby controlling the movement of the screws.

[0045] As the screws move continuously inside the conveyor track 31, they pass by the position of the screening brush 7. The screening brush 7 adjusts the screws and removes excess screws and most screws with abnormal postures from the conveyor track 31, ensuring that the screws can be conveyed in an orderly manner on the conveyor track 31 and then moved to the storage track 312.

[0046] Since a large number of screws will be conveyed to the storage track 312, when the storage track 312 is full of screws, the screws on the conveying track 31 will not be able to move to the storage track 312. The amount of screws can be detected by the full material detector 10. When the amount reaches a certain amount, the roller 4 needs to be controlled to stop rotating and stop the screws from being moved to the conveying track 31.

[0047] The full material detector 10 controls the number of screws fed into the storage track 312 by irradiating with optical fiber, and controls the roller 4 to stop rotating in time. When there is space in the storage track 312, it controls the screws on the conveying track 31 to move to the storage track 312 so that the screws can continue to be conveyed.

[0048] The screw is also moved on the storage track 312 by the second air pressure plate 9, allowing the screw to move continuously on the storage track 312. As the screw moves, it is controlled to move into the position of the sliding gate 32. The device is equipped with a spring on the sliding gate 32, which limits the screw and prevents it from easily falling off the storage track 312. When the screw is needed, the sliding gate 32 can be pressed to release the screw from its limit. After the screw is removed, the sliding gate 32 will be controlled by the spring to return to its initial position and continue to limit the screw, thus meeting the needs of use.

[0049] This device can both convey and fasten screws. The fastening mechanism 14 is also equipped with a feeding channel 19, a third air-blowing plate 20, and a dust collection box 21. The dust collection box 21 uses negative pressure to suck away dust and impurities from the screws, improving the product fastening yield. Screws installed below the feeding channel continuously move on the storage track 312, which will move the screws to the feeding channel 19. Under the blowing of the third air-blowing plate 20, the screws on the feeding channel 19 will be continuously blown to the moving plate 18. The dust and impurities generated by the screws during the movement of the screws in the feeding channel 19 will be blown off by the third air-blowing plate 20 and fall into the dust collection box 21.

[0050] During the screw fastening operation, the screw is delivered to the moving plate 18. At this time, the moving plate 18 is moved by the push cylinder 17, moving the moving plate 18 with the screw to the position of the guide copper sleeve 16. The fastening cylinder 1412 pushes the nail suction cylinder 142 to move downward. After the vacuum tube contacts the screw, a negative pressure is formed. After the negative pressure gauge outputs an OK signal, the fastening cylinder is released, causing it to extend and drive the servo motor and vacuum suction tube to reset upward. At the same time, the vacuum suction tube 15 moves downward. The vacuum suction tube 15 contacts the screw, and under the action of the nail suction cylinder 142, the screw is attracted to the vacuum suction tube 15. At the same time, the fastening cylinder 1412 fastens the screw.

[0051] To facilitate use, an adapter bracket is installed on the outside of the locking mechanism 14 for connecting external equipment to ensure stable operation of the locking mechanism 14. Additionally, an optical fiber head and an optical fiber amplifier are installed on the moving plate 18 to detect and determine the presence or absence of screws on the moving plate 18. An optical fiber amplifier is also installed on the side of the feeding channel 19 to detect the presence or absence of screws.

[0052] The full-load detector 10 in this device is a Huayifeng through-beam fiber optic FT-S10, which is used in conjunction with a Huayifeng fiber optic amplifier FR-J16. The origin sensor 12 is a Huayifeng miniature slotted photoelectric sensor LU-T45.

[0053] It should be noted that the motor 13 is a device or equipment existing in the prior art, or a device or equipment that can be implemented by the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail here.
