Description

Technical Field

[0001] This utility model belongs to the field of screw feeding technology, and in particular relates to a screw aligning and feeding device. Background Technology

[0002] In the process of industrial automation production, screws are key fasteners, and their efficient and precise feeding is crucial to ensuring the smoothness of the production process and the stability of product quality.

[0003] Current screw feeding equipment on the market has many shortcomings in the screw alignment process. Some machines fail to achieve good alignment during screw conveying, making it difficult for screws to be arranged in a predetermined orderly manner. Screw misalignment, overlap, and directional confusion frequently occur. This not only hinders subsequent assembly processes and reduces assembly efficiency, but also may affect the overall performance and quality of the product due to improper screw assembly, increasing the defect rate. Utility Model Content

[0008] Furthermore, the scraping assembly includes a vertical plate installed at the front end of the hopper, a pair of sliding rods above the vertical plate, a break below the vertical plate, and conveying guide rails located within the break. A scraping plate is provided on the sliding rods, and a conveying port is provided at the bottom of the scraping plate directly opposite each conveying guide rail. A scraping cylinder is provided on the vertical plate, and the drive shaft of the scraping cylinder is connected to the scraping plate.

[0017] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figures 1-4As shown, the screw aligning and feeding device includes a machine base 1. The machine base 1 is equipped with a linear vibrator 2 and a hopper 3 at the front and rear, respectively. The linear vibrator 2 is equipped with several conveying guide rails 4. The hopper 3 is equipped with a bottom plate 5 that is inclined downwards and forwards. The bottom plate 5 has a notch 6 corresponding to each conveying guide rail. The machine base 1 is also equipped with a slide 7. The slide 7 is equipped with a slide plate 8. The slide plate 8 is equipped with a push plate 9 facing the notch. The top surface of the push plate 9 is inclined downwards and forwards. The top surface of the push plate 9 has a support groove 10 facing downwards. The machine base 1 is also equipped with a push cylinder 11. The drive shaft of the push cylinder 11 is connected to the push plate 9. The front end of the hopper 3 is equipped with a scraping assembly.

[0021] When using this device, a certain number of screws are first placed in the hopper. Guided by the inclined angle of the base plate, the screws converge towards the notch in the base plate under gravity, preparing for subsequent material distribution. Next, the push cylinder drives the slide plate to move upwards along the slide frame. The push plate moves synchronously with the slide plate, and the support groove on the top surface of the push plate extends into the hopper through the notch. A single screw falls into the support groove, with the screw head engaged and the rod facing downwards. Subsequently, the push cylinder continues to drive the push plate upwards, and the push plate, carrying the screws, exits from the notch and moves to the slot at the end of the conveyor rail. The front end of the top surface of the push plate aligns with the end of the rail, and the screw slides onto the conveyor rail.

[0022] When the linear vibrator operates, it moves the screw forward along the conveyor rail. At the same time, the scraper assembly also starts working. With the cooperation of the scraper assembly, the screw with its head facing forward and in the correct posture passes through and moves smoothly forward along the conveyor rail. Excess screws or screws with incorrect posture are pushed back into the hopper.

[0023] In this structure, such as Figure 2 The front end of the hopper 3 has several slots 12, the tail end of the conveying guide rail 4 is located inside the slots, and the inner wall of the front end of the hopper 3 has downward-facing slopes 13 on both the left and right sides of the slots.

[0024] The front end of the hopper has several slots, and the tail end of the conveyor rail is located inside the slots. This allows the screws to enter the conveyor rail more smoothly from the hopper. At the same time, the sloping design helps to push excess or incorrectly positioned screws back into the hopper by the scraping component.

[0025] As a preferred structure, combined with Figures 2-3 The scraping assembly includes a vertical plate 14 installed at the front end of the hopper 3. A pair of sliding rods 15 are provided above the vertical plate 14. A break 16 is opened at the bottom of the vertical plate 14, and the conveying guide rails 4 are all located within the break. A scraping plate 17 is provided on the sliding rods 15. The bottom of the scraping plate 17 is opened with a conveying port 18 facing each conveying guide rail. A scraping cylinder 19 is provided on the vertical plate, and the drive shaft of the scraping cylinder 19 is connected to the scraping plate 17.

[0026] When using this device, the scraper cylinder drives the scraper to reciprocate along the slide bar. The scraper can scrape excess or irregularly arranged screws on the conveyor rail back into the hopper, ensuring the orderly arrangement of screws on the conveyor rail.

[0027] In addition, such as Figure 1 The machine base 1 is equipped with a connecting frame 20, and the connecting frame 20 has guide bars 21 facing each conveying guide rail. The screws are conveyed forward along the conveying guide rails under the action of the linear vibrator. The guide bars further constrain and guide the conveying direction and position of the screws to ensure that the screws are accurately conveyed to the subsequent assembly station.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
