Description

Technical Field

[0001] The present invention relates to a feeding device, and more particularly to an automatic screw sorting and feeding device. Background Art

[0002] In the current booming modern manufacturing industry, production efficiency and product quality have become the key factors for enterprises to gain a foothold in the market. This has made automated equipment in the production process increasingly important. As a basic part widely used in the assembly of various products, the efficient and accurate feeding of screws is directly related to the smoothness of the entire production process. However, the traditional screw feeding methods have many drawbacks and are no longer able to meet the needs of today's rapidly developing manufacturing industry. Manual feeding is a common traditional method. Workers need to manually pick up screws one by one and place them in the corresponding positions. This process is not only extremely inefficient and difficult to keep up with the rhythm of large-scale production, but also consumes a huge amount of physical strength of workers. Long-term operation is likely to cause worker fatigue, which may lead to operational errors. At the same time, manual operation is greatly affected by subjective factors and it is difficult to ensure the accuracy and consistency of each feeding. The situations of missing or misplacing screws often occur, which greatly affects the product quality and increases the production cost. Some enterprises use vibrating bowls for screw feeding. Although vibrating bowls can achieve a certain degree of automation to some extent, for screws, which have diverse specifications, similar shapes and small volumes, their sorting effect is not ideal. When the vibrating bowl is working, problems such as screws winding around each other and jamming of materials are likely to occur, resulting in the interruption of feeding and affecting the continuity of production. Moreover, the applicable range of the vibrating bowl is limited. When the specifications or shapes of the screws change, complex debugging or even replacement of the equipment is often required, which is costly and time-consuming. In addition, some existing simple feeding devices lack effective counting and quality inspection functions for screws, and cannot monitor the feeding process in real time, making it difficult to ensure the accuracy of the feeding quantity. Once the situation of insufficient or excessive feeding occurs, it will have a serious impact on the subsequent assembly work and may even lead to quality problems in the entire batch of products. The manufacturing industry has higher and higher requirements for the intelligence and automation of the production process, and the traditional screw feeding methods cannot meet this trend.

[0003] Therefore, those skilled in the art are committed to developing a feeding device that can automatically sort, feed efficiently and accurately, adapt to different specifications of screws, and has counting and quality inspection functions. Summary of the Invention

[0010] Further, the pressing component includes a feeding groove opened at the upper edge of the aggregate box body. Screws are conveyed to the feeding groove through the first feeding seat, and the screws in the screw feeding groove are conveyed towards the feeding component direction through a vibration mechanism.

[0011] Further, a fixing plate is arranged on the outer rear half section of the feeding groove. An air vent box is arranged inside the fixing plate.

[0012] Further, a second material return table is arranged inside the aggregate box body on one side of the aggregate table. A first material return table is arranged between the second material return table and the air vent box.

[0013] Further, the feeding component includes a mounting plate. The mounting plate is connected to the outer wall of the aggregate box body. A positioning frame is arranged at the upper end of the mounting plate. The upper end of the positioning frame has a long strip-shaped through opening.

The material limiting plate slidably passes through the positioning frame and is used for blocking the upper ends of the material conveying cylinders.

[0015] The beneficial effects of the present invention are as follows: 1. The power cylinder of the material storage mechanism drives the material storage seat to move up and down, so that the screws can quickly slide down to the aggregate assembly. With the inclined section design of the aggregate table, the screws can be quickly gathered. The lifting air cylinder of the feeding assembly pushes the first and second feeding seats and the material guiding table to move synchronously, and efficiently transfers the screws to the material conveying groove. The vibration mechanism and the air jet nozzles of the ventilation box cooperate with each other to prompt the screws to quickly move towards the material conveying assembly. In the material conveying assembly, the electric motor drives the screw rod to drive the sliding table for precise positioning, and the air inlet nozzle blows air for feeding. The whole process is closely coordinated, greatly shortening the feeding time and significantly improving the production efficiency.

[0016] 2. Through the inclined design of the aggregate table and the cooperation of the feeding seat and the material guiding table, the screws can be guided to move orderly, reducing chaos. The material blocking plate of the material conveying groove and the air jet nozzles of the ventilation box play a role in limiting the screws, preventing them from falling or shifting. The design of the material leakage opening, the blocking block and the limiting plate of the sliding table, combined with the precise control of the pushing air cylinder, ensures that only one screw falls into the material conveying cylinder each time. Cooperating with the counter for real-time counting, the feeding quantity is precisely controlled, ensuring the feeding accuracy and reducing the defective rate of the products.

[0017] 3. The device realizes the automatic operation of screw feeding. Workers only need to put the screws into the material storage box body, and subsequent sorting, conveying, feeding and other links are all automatically completed by the equipment, greatly reducing the operation steps and physical consumption of workers, reducing the labor intensity, and avoiding operation mistakes caused by manual fatigue.

[0018] 4. The structural design of parts such as the material storage mechanism, the feeding assembly, and the material conveying assembly is relatively flexible. Relevant parameters can be set through the operation display panel, and the lifting height of the material storage seat, the vibration frequency of the vibration mechanism, the moving speed of the sliding table, etc. can be adjusted according to the characteristics of different specifications of screws, such as size and weight, so that the equipment can adapt to the feeding requirements of various specifications of screws, improving the versatility and applicability of the equipment.

[0019] 5. The device is equipped with a counter, which can count the feeding quantity in real time, providing accurate data for production management and facilitating the enterprise to reasonably arrange the production plan. The stop air cylinder and the material limiting plate can flexibly control the feeding of the material conveying cylinder, facilitating the suspension or adjustment of the feeding process in cases such as equipment maintenance and material replenishment, improving the convenience and flexibility of production management.

[0043] The pressing component 33 includes a screw conveying groove 35 opened at the upper edge of the aggregate box body 3. Screws are conveyed to the screw conveying groove 35 through the first feeding seat 18, and the screws in the screw conveying groove 35 are conveyed towards the feeding component 6 through a vibration mechanism. The vibration mechanism is a prior art, such as an electromagnetic vibration mechanism, an eccentric wheel vibration mechanism, etc. For example, the electromagnetic vibration mechanism generates vibration through the periodic change of electromagnetic force, has the advantages of stable vibration frequency and easy control, and is suitable for occasions with high requirements for vibration precision; the eccentric wheel vibration mechanism has a simple structure and low cost, but relatively poor vibration stability, and is suitable for general feeding scenarios with not particularly high requirements for precision.

[0044] The vibration mechanism is arranged on the aggregate box body 3. A baffle 36 is arranged on the outer side of the front half section of the screw conveying groove 35 to prevent the screws accumulated in the screw conveying groove 35 from falling.

[0045] A fixing plate 37 is arranged on the outer side of the rear half section of the screw conveying groove 35. An air vent box 38 is arranged inside the fixing plate 37.

[0047] The feeding component 6 includes a mounting plate 56, which is connected to the outer wall of the aggregate box body 3. A positioning frame 57 is provided at the upper end of the mounting plate 56.

A guide rail 60 is provided in the positioning frame 57 and is arranged at the upper end of the mounting plate 56. A plurality of sliding platforms 61 are slidably arranged on the guide rail 60. A material leakage opening 62 is arranged on the inner side of each sliding platform 61. A baffle 63 is arranged in the lower half of the material leakage opening 62. A plurality of feeding cylinders 65 that cooperate with the respective material leakage openings 62 are arranged on the mounting plate 56. Each feeding cylinder 65 extends downward and has an air inlet nozzle 66 in the lower half. The lower end of the feeding cylinder 65 is connected to the assembly unit of the next process through a connecting pipe.

The middle sections of the sliding platforms 61 are simultaneously threaded through a screw rod 67. The two ends of the screw rod 67 are rotatably connected to the positioning frame 57. A motor 68 for driving the screw rod 67 to rotate is arranged on the outer side of the positioning frame 57. A limiting plate 69 is slidably arranged at the upper end of the sliding platform 61.

The propulsion cylinder 71 is connected to the rear end of the sliding platform 61 through a mounting frame 72.

[0048] A counting support 73 is arranged on the outer side of the long strip-shaped through opening 58. The counting support 73 is in a Z shape.

The material limiting plate 76 slidably passes through the positioning frame 57 and is used to block the upper ends of the respective feeding cylinders 65.

[0049] To ensure the long-term stable operation of the screw automatic sorting and feeding device, regular maintenance is required. The door sealing rubber strip of the storage box body should be regularly inspected. If it is aged or damaged, it needs to be replaced in time to prevent dust from entering the box body and contaminating the screws. The piston rod surfaces of the power cylinder and the lifting cylinder should be regularly lubricated to ensure smooth movement and extend the service life of the cylinder. The air inlet and the long strip-shaped jet nozzle of the ventilation box are easily blocked by dust and should be cleaned weekly to ensure the jetting effect. The connection between the motor and the screw rod should be regularly inspected for tightness to avoid looseness affecting the movement accuracy of the sliding platform. At the same time, a comprehensive inspection and debugging of the equipment should be carried out every six months to ensure that the performance of each component is in the best state.

[0050] The optimal working principle of the present invention is as follows: The automatic screw sorting and feeding device mainly consists of a storage mechanism, an aggregate component, an aggregate box body, a feeding component, a pressing component, and a feeding component. Each component works together to achieve automatic screw sorting and feeding. The specific working principle is as follows: The screws to be fed are directly placed on the storage seat 12 in the storage box body 7. The operation display panel 11 can be used to set relevant parameters and control the operation of the power cylinder 16. The power cylinder 16 drives the storage seat 12 to move up and down along the guide rod 15. When the storage seat 12 rises, the screws approach the long strip-shaped discharge port 9 and slide down along the guide plate 10 under the action of gravity to the aggregate table 31 of the aggregate component 2. When feeding is not required, the storage seat 12 can be controlled to descend. The first aggregate inclined section 31a at the upper end of the first half of the aggregate table 31 and the second aggregate inclined section 32a at the upper end of the second half are helpful for the collection of screws. Under the action of the inclined surface, the screws roll and gather towards the position where the second feeding seat 19 is located; the lifting cylinder 29 in the driving mechanism 23 works to push the lifting plate 28 upward. The lifting plate 28 drives the first feeding seat 18 and the second feeding seat 19 to rise synchronously. The state after rising is as Figure 5 shown. The first inclined surface 20 of the first feeding seat 18, the second inclined surface 21 of the second feeding seat 19, and the third inclined surface 27 of the guide table 26 have the same inclined direction. During the rising process, the screws on the aggregate table slide upward along these inclined surfaces and enter the guide table 26 between the first feeding seat 18 and the second feeding seat 19. Repeating this process, the first feeding seat 18 transfers the screws on the guide table 26 to the feeding chute 35. The first feeding seat 18 conveys the screws to the feeding chute 35. The vibration mechanism provided on the aggregate box body 3 is prior art, and any prior art that can achieve this function can be started to make the screws in the feeding chute 35 convey towards the feeding component 6. The baffle 36 on the outer side of the first half of the feeding chute 35 prevents the screws from falling; the ventilation box 38 is connected to the blower through a hose. The blower inputs air from the air inlet 39 into the ventilation box 38, and the air is ejected from the long strip-shaped nozzle 50 to apply a force to the screws in the feeding chute 35, assisting the screws to move towards the feeding component 6 and limiting them at the same time to prevent the screws from sliding out of the feeding chute 35 due to the vibration brought by the vibration mechanism. One end of the ventilation box 38 adopts an arc transition, which can effectively avoid the screws from getting stuck; The screw at the output end of the material feeding chute 35 enters the long strip-shaped through hole 58 through the feeding notch 59 on the positioning frame 57. The counter 77 is installed on the counting bracket 73 to count the screws passing through the feeding notch 59. The motor 68 drives the screw 67 to rotate, and the screw 67 drives the sliding table 61 to slide on the guide rail 60. When the material leakage port 62 on the sliding table 61 moves to align with the feeding notch 59, the screw is supported by the material blocking port 70. Subsequently, when the sliding table 61 is driven by the screw 67 to move to the corresponding material conveying cylinder 65, the limiting plate 69 is pushed backward by the propulsion cylinder 71. The material blocking port 70 is smaller than the material leakage port 62, so that the screw falls into the material leakage port 62. The air inlet nozzle 66 inputs air into the material conveying cylinder 65 to blow the screws entering the material conveying cylinder 65 towards the connecting pipe and convey them to the assembly unit of the next process. The material blocking cylinder 75 on the outer wall of the aggregate box body 3 can control the limiting plate 76 to block the upper end of the material conveying cylinder 65 to realize the control of the material feeding process.

[0051] During the entire feeding process, some screws may not enter the material feeding assembly 6 smoothly. These screws will fall into the first return material table 55 and the second return material table 53 in the aggregate box body 3 for subsequent feeding operations.

[0052] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
