Description

Technical Field

[0001] This utility model relates to the field of screw fastening device technology, specifically a screw feeding device for a screw fastening machine. Background Technology

[0002] The screw feeding device for screw fastening machines is a specialized piece of equipment used to deliver screws to the machine during screw fastening operations. This device, through its screening structure, can filter screws during the feeding process, ensuring that screws meeting specifications are accurately delivered to the fastening area. This provides qualified screw raw materials for the stable operation of the screw fastening machine, guaranteeing the quality and efficiency of the fastening operation. It is suitable for various production scenarios requiring batch screw fastening.

[0003] Traditional screw feeding devices for screw fastening machines have several shortcomings. Most devices lack effective screening mechanisms, failing to identify and filter screws based on their connection style during transport. This results in non-compliant screws entering the fastening process, easily causing fastening quality problems and potentially damaging the screw fastening machine, affecting its stability and reliability. Furthermore, the existing devices have poorly designed conveying structures, making it difficult to guarantee the accuracy of screw delivery and further increasing the risk of unqualified screws participating in the fastening operation, failing to meet the high precision and efficiency requirements of modern production. In addition, some devices have poor screw guidance during transport, easily causing screw jamming and reducing feeding efficiency. Therefore, we propose a screw feeding device for screw fastening machines. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing screw fastening devices lack an effective screening mechanism, making it impossible to identify and filter screw connection patterns during transmission, resulting in unsuitable screws entering the fastening stage and affecting the stability and reliability of the equipment. To address the aforementioned technical problems, this application provides a screw feeding device for a screw fastening machine, comprising a bracket, a housing fixedly connected to the upper outer wall of the bracket, a driving device fixedly connected to one side of the upper outer wall of the housing, a transmission device connected to one side of the driving device, a limiting plate fixedly connected to one side of the upper outer wall of the housing, a connecting plate provided on one side of the limiting plate, a screw body movably connected to the upper outer wall of the connecting plate, a filter plate fixedly connected to one side of the outer wall of the limiting plate, a plurality of ball bearings connected to the side of the filter plate away from the limiting plate, a guide plate fixedly connected to one side of the inner wall of the housing, and a screw fastening machine body movably connected to the other side of the transmission device.

[0005] In some embodiments, a third inclined plate is fixedly connected to the upper end of the inner wall of the box, a cylinder is connected to the lower end of the third inclined plate, a crossbar is movably connected to the lower end of the cylinder, movable plates are movably connected to both sides of the crossbar, slide rails are fixedly connected to both outer walls of the movable plates, and a slide rod is slidably connected to one side of the inner wall of the slide rail.

[0006] In some embodiments, a first lifting plate is fixedly connected to one outer wall at the upper end of the movable plate, a second lifting plate is fixedly connected to one outer wall at the upper end of the movable plate, a third lifting plate is fixedly connected to one outer wall at the upper end of the movable plate, a first inclined plate is threadedly connected to one inner wall of the box, a second inclined plate is threadedly connected to one inner wall of the box, and a placement plate is threadedly connected to one inner wall of the box.

[0007] In some embodiments, a guide plate provided on one side of the inner wall of the box is correspondingly connected to a filter plate and a ball bearing provided on one side of the limiting plate.

[0008] In some embodiments, a placement plate provided on one side of the inner wall of the box is correspondingly connected to a guide plate provided on one side of the inner wall of the box.

[0009] In some embodiments, the first lifting plate, the second lifting plate, and the third lifting plate are fixedly connected to one side of the upper end of the movable plate in a three-level increment.

[0010] In some embodiments, the first inclined plate, the second inclined plate, and the third inclined plate are respectively connected to the outer wall of one side of the first lifting plate, the second lifting plate, and the third lifting plate, and are also threaded to one side of the inner wall of the box in a three-level increment.

[0011] In some embodiments, the lower end of the connecting plate is fixedly connected to the upper outer wall of the third inclined plate, and its upper outer wall is recessed inward.

[0012] This utility model has at least the following beneficial effects: 1. In use, this utility model demonstrates outstanding performance in ensuring conveying quality through its screening structure comprised of a filter plate, ball bearings, and guide plates. One side of the filter plate has a slanted section and multiple ball bearings, positioned precisely at the top of the normal connection height between the screw body and the connecting plate. When a screw with a non-standard connection pattern moves to the side of the filter plate during conveying, it is blocked by the filter plate and guided to the guide plate on the inner wall of the housing, eventually returning to the housing for refeeding. Screws with a standard connection pattern, however, can pass smoothly through the filter plate and be conveyed to the locking area for operation. This screening mechanism effectively avoids quality problems and device damage risks caused by unqualified screws entering the locking process, ensuring the stability and reliability of subsequent locking operations.

[0013] 2. In use, the lifting and conveying structure, composed of a cylinder, a crossbar, a movable plate, a first lifting plate, a second lifting plate, a third lifting plate, a first inclined plate, a second inclined plate, and a third inclined plate, plays a crucial role in improving conveying efficiency. The cylinder drives the movable plate through the crossbar, causing the three lifting plates to rise synchronously, and these lifting plates and their corresponding inclined plates all have progressively increasing inclination angles. When the screw body is placed on the placement plate inside the housing, it first gathers on the first lifting plate, is then lifted by it, and is conveyed along the first inclined plate to the second lifting plate. Next, it is lifted by the second lifting plate and conveyed along the second inclined plate to the third lifting plate. Finally, it is lifted by the third lifting plate and conveyed along the third inclined plate to the connecting plate, forming an orderly stepped conveying path. This design greatly accelerates the conveying speed of the screw from the bottom of the housing to the connecting plate, significantly improving the overall conveying efficiency.

[0014] 3. In use, the recessed design of the upper outer wall of the connecting plate, which makes the middle part lower than the sides, can guide the screw body to gather well on the connecting plate. Together with the transmission device at the lower end, it further ensures the orderly movement of the screw during the conveying process, and provides support for efficient and high-quality feeding operations.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 1-3 This utility model provides a technical solution: a screw feeding device for a screw fastening machine, including a bracket 1, a housing 2 fixedly connected to the upper outer wall of the bracket 1, a driving device 3 fixedly connected to one side of the upper outer wall of the housing 2, a transmission device 4 connected to one side of the driving device 3, a limiting plate 5 fixedly connected to one side of the upper outer wall of the housing 2, a connecting plate 6 provided on one side of the limiting plate 5, a screw body 7 movably connected to the upper outer wall of the connecting plate 6, a filter plate 8 fixedly connected to one side of the limiting plate 5, a plurality of balls 9 connected to the side of the filter plate 8 away from the limiting plate 5, a guide plate 10 fixedly connected to one side of the inner wall of the housing 2, the guide plate 10 provided on one side of the inner wall of the housing 2 correspondingly connected to the filter plate 8 and the balls 9 provided on one side of the limiting plate 5, and a screw machine body 11 movably connected to the other side of the transmission device 4.

[0019] In this embodiment, a bracket 1 is designed, and a box 2 is fixedly connected to the upper end of the bracket 1. The screw body 7 can be placed inside the box 2. A drive device 3 is fixedly connected to the outer wall of the upper end of the box 2. A transmission device 4 is connected to one side of the drive device 3. The transmission device 4 is located on the outer wall of the upper end of the box 2. A limit plate 5 is fixedly connected to the upper end of the box 2. A connecting plate 6 is fixedly connected to the outer wall of the upper end of the box 2. The connecting plate 6 is located on the upper end of the transmission device 4. The screw body 7 can be connected to the middle of the upper outer wall of the connecting plate 6 on one side of the limit plate 5. Therefore, the screw body 7 can be conveyed to the upper end of the connecting plate 6 through the lifting mechanism, and then transmitted through the drive device 3 and the transmission device 4, thereby completing the feeding operation. However, existing methods mostly use vibration transmission to convey the screw body 7. During the lifting process, in order to limit the screw body 7, the upper outer wall of the connecting plate 6 is concave, that is, the middle is lower than the two sides. The screw body 7 can be well gathered on the connecting plate 6 and transmitted through the transmission device 4 at the lower end of the connecting plate 6. During the feeding process, the screw body 7 will accumulate in different ways on the upper end of the connecting plate 6 and the transmission device 4. If it is not transmitted in the specified way, quality problems will occur during the locking operation, which will lead to damage to the device. Therefore, a filter plate 8 is fixedly connected to one side of the outer wall of the limiting plate 5. The filter plate 8 has a beveled section on one side and multiple balls 9 are provided on one side of the beveled section. The height of the filter plate 8 is just at the top of the normal connection height between the screw body 7 and the connecting plate 6. Therefore, when the screw body 7 of other connection types moves to the side of the filter plate 8, it will be guided by the filter plate 8 to the guide plate 10 provided on the inner wall of the box 2 and then return to the box 2 for the feeding operation to be repeated. The screw body 7 of the normal connection type will be transmitted to the screw machine body 11 on the side of the box 2 for the locking operation.

[0020] Example 2: Please refer to Figure 1-4A third inclined plate 22 is fixedly connected to the upper end of the inner wall of the housing 2. The lower end of the connecting plate 6 is fixedly connected to the upper outer wall of the third inclined plate 22, and its upper outer wall is concave inward. A cylinder 12 is connected to the lower end of the third inclined plate 22. A crossbar 13 is movably connected to the lower end of the cylinder 12. Movable plates 14 are movably connected to both sides of the crossbar 13. Slide rails 15 are fixedly connected to both outer walls of the movable plates 14. A slide rod 16 is slidably connected to one side of the inner wall of the slide rails 15. A first lifting plate 17 is fixedly connected to one side of the upper outer wall of the movable plate 14. A second lifting plate 18 is fixedly connected to one side of the upper outer wall of the movable plate 14. A third lifting plate is fixedly connected to one side of the upper outer wall of the movable plate 14. 19. The first lifting plate 17, the second lifting plate 18, and the third lifting plate 19 are fixedly connected to one side of the upper end of the movable plate 14 in a three-level increment. The first inclined plate 20 is threadedly connected to one side of the inner wall of the box body 2, and the second inclined plate 21 is threadedly connected to one side of the inner wall of the box body 2. The first inclined plate 20, the second inclined plate 21, and the third inclined plate 22 are respectively connected to the outer wall of one side of the first lifting plate 17, the second lifting plate 18, and the third lifting plate 19, and are also threadedly connected to one side of the inner wall of the box body 2 in a three-level increment. The placement plate 23 is threadedly connected to one side of the inner wall of the box body 2, and the placement plate 23 provided on one side of the inner wall of the box body 2 is correspondingly connected to the guide plate 10 provided on one side of the inner wall of the box body 2.

[0021] In this embodiment, a third inclined plate 22 is connected to the upper end of the inner wall of the housing 2, and a cylinder 12 is connected to the lower end of the third inclined plate 22. The lower end of the cylinder 12 is movably connected to a movable plate 14 via a crossbar 13. The cylinder 12 has a certain tilt angle. Slide rails 15 and slide rods 16 are respectively connected to the outer walls on both sides of the movable plate 14. The slide rods 16 are fixedly connected to one side of the inner wall of the housing 2, and the slide rails 15 are fixedly connected to one side of the outer wall of the movable plate 14. A first lifting plate 17, a second lifting plate 18, and a third lifting plate 19 are respectively fixedly connected to the upper end of the movable plate 14. A first inclined plate 20, a second inclined plate 21, and a third inclined plate 22 are respectively connected to one side of the inner wall of the housing 2. The first lifting plate 17 is connected to the first inclined plate 20, the second lifting plate 18 is connected to the second inclined plate 21, and the third lifting plate 19 is connected to the third inclined plate 22. Therefore, when the cylinder 12 is started, the cylinder 12 will move through the crossbar 13. 3. The drive plate 14 is lifted, which in turn lifts the first lifting plate 17, the second lifting plate 18, and the third lifting plate 19 simultaneously. The first lifting plate 17, the second lifting plate 18, the third lifting plate 19, the first inclined plate 20, the second inclined plate 21, and the third inclined plate 22 all have an inclination angle and are connected in ascending order. Therefore, when the screw body 7 is placed on the placement plate 23 provided on the inner wall of the housing 2, some of the screw body 7 will gather on the first lifting plate 17. At this time, the first lifting plate 17 will be lifted and the screw body 7 will be transferred along the first inclined plate 20 to the second lifting plate 18. Then the second lifting plate 18 will be lifted and the screw body 7 will be transferred along the second inclined plate 21 to the third lifting plate 19. Finally, the third lifting plate 19 will be lifted and the screw body 7 will be transferred along the third inclined plate 22 to the connecting plate 6, and then the subsequent transfer operation will be carried out. This method greatly improves the transfer efficiency.
