Description

Technical Field

[0001] The utility model relates to the technical field of screw feeding, in particular to an automatic feeding system for micro screws. Background Art

[0002] Screws are a common fastener, widely used in machinery, electrical appliances, and buildings. In modern production plants, where assembly is the main process, screws are used extensively as fixing parts. There are many types of screws, with commonly used ones including hexagon socket screws and cross-slot screws. Different types of the same screw differ not only in some basic dimensions, such as head width and head thickness, but also in the threaded portion. Based on the nominal diameter, they can be divided into various types, ranging from M0.6 to M20. Types M2 and below are generally considered micro screws. Due to their small diameter, they are tiny fasteners used to connect product materials. Although they are tiny in shape, they can play a key role in critical locations.

[0003] Due to the small size of micro screws, they are prone to inconvenience during storage and use. When using them, general staff need to find a sufficient number of micro screws from the material box and bring them to the assembly workshop. Manual search and transportation not only wastes time and affects processing efficiency, but also easily leads to loss during transportation. There are already fully automated nail supply systems in the existing technology, but when faced with such micro screws, track nail feeding is usually used in conjunction with a disc turntable to discharge and sort the screws. Because the screws are discharged by the turntable, the positioning accuracy is very poor, which affects the accuracy of nail removal and locking. Summary of the Invention

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0026] First, combine Figure 1 An automatic feeding system for micro screws according to an embodiment of the present invention is described, which is used for automatic feeding of micro screws and has a wide range of application scenarios.

[0027] like Figure 1 As shown, an automatic feeding system for micro screws according to an embodiment of the present invention comprises a base plate 1, a loading module, a nail feeding track, a vibrator 4, a rejection module and a feeding module.

[0028] Specifically, if Figure 1 As shown, the loading module is installed on the base plate 1 and is used to store and discharge screws. The loading module includes a belt conveyor 21, which is installed on the base plate 1 at an angle. The belt conveyor 21 is equipped with baffles 22 on the top three sides. The belt conveyor 21 and the baffles 22 on the top three sides form a loading hopper. The belt conveyor 21 automatically discharges the screws in the loading hopper.

[0029] Specifically, if Figures 1 and 2 As shown, the nail feeding track is set on one side of the loading module to receive the screws discharged by the loading module. The nail feeding track consists of a receiving section 31 and a discharge section 32. The input end of the discharge section 32 is connected to the receiving section 31, and the output end of the discharge section 32 is connected to the feeding module. The receiving section 31 is connected to the loading module. The discharge section 32 is equipped with a discharge trough 321 for placing screws in the correct posture.

[0030] Specifically, if Figures 1 and 2 As shown, the vibrator 4 is arranged on the base plate 1 and is connected to the nail feeding track, and is used to drive the screws on the nail feeding track to move forward in sequence, so as to realize the movement of the screws on the nail feeding track.

[0031] Specifically, if Figures 1 and 2 As shown, the rejection module is installed on the nail feeding track to remove screws with incorrect postures. The rejection module includes a nail blowing air pipe 51 and a detector 52. The nail blowing air pipe 51 is installed in the unloading section 32 to remove screws with incorrect postures on the nail feeding track; the detector 52 is installed in the unloading section 32 to detect the posture of the screws on the nail feeding track.

[0032] Further, if Figure 1 As shown, the rejection module further includes: a collection box 53, which is located on one side of the blanking section 32 and directly faces the nail blowing air pipe 51, and is used to collect the rejected screws.

[0033] Specifically, if Figure 1As shown, the feeding module is located on one side of the nail feed track, feeding screws from the track one by one in the correct position. The feeding module comprises a bracket 61, a cylinder 62, and a feeding block 63. Bracket 61 is mounted on the base plate 1; cylinder 62 is mounted on top of bracket 61; feeding block 63 is located at the output end of cylinder 62. A vacuum suction groove 631 is provided at the junction of feeding block 63 and the nail feed track.

[0034] Working principle:

[0035] After the screws are put into the loading bin, the belt conveyor 21 brings the screws to the receiving section 31 of the nail feeding track, and the vibrator 4 vibrates and drives the screws forward to the loading section. The screws in the unloading section 32 continue to move forward with the correct posture after being screened by the nail blowing air pipe 51, and the wrong ones will be blown to the collection box 53. The screws in the unloading section 32 continue to vibrate to the feeding block 63, where the external vacuum air source in the feeding block 63 will suck the screws into the vacuum nail suction groove 631, and at the same time, a signal will be given to the cylinder 62 after the vacuum value is met. The cylinder 62 will drive the feeding block 63 to send out a single nail, completing the separate feeding of the screw. After the external electric batch module is removed, the cylinder 62 can be retracted immediately, and the vibrator 4 will vibrate the waiting nail into the vacuum nail suction groove 631, and the next nail can be fed immediately to meet the high-speed feeding.

[0036] Above, refer to Figures 1 and 2 The present invention describes an automatic feeding system for micro screws according to an embodiment of the present invention. The system uses a belt to load the material, which is convenient for manual operation, saves time and effort, and adopts direct vibration conveying and air blowing screening to directly adjust the screw posture, and then uses vacuum adsorption to position the screw, and uses the cylinder 62 to cut out the screw, ensuring the feeding of a single screw, facilitating manual locking operations, and can solve the problem of low positioning accuracy caused by large deviation of the discharge position, while improving the positioning accuracy without affecting the production rhythm, and facilitating automatic material retrieval.
