[0002] As a vital fastening element in mechanical and electronic equipment, screws are in great demand and have a wide range of applications. In many modern devices, the use of pre-assembled screws not only simplifies the assembly process, but also improves overall production efficiency. However, the current screw assembly relies on manual operation, which not only increases labor costs, but also limits the level of automation in production.

[0003] In order to solve the above technical problems, those skilled in the art often use a transport device to transport the screw to the assembly device side, and then the assembly device assembles the screw. However, the above technical solution does not take into account that because the screw assembly process requires the use of screws of various specifications and lengths, this complexity requires workers or assembly machines to select different types of screws during the assembly process, thereby reducing work efficiency. In addition, the existing screw transportation and feeding methods often make it difficult to ensure the consistency of the screw direction, which leads to the unsmoothness of the automatic assembly process.

[0004] Based on this, there is an urgent need for an automated conveying device for screw feeding to solve the above technical defects. Summary of the invention

Any technical personnel in this field may make several possible changes and modifications without departing from the concept of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims of the present application.

[0056] The present invention is further described in detail below in conjunction with specific implementation methods, but the embodiments of the present invention are not limited thereto.

[0057] Example 1

[0058] like Figure 1-2The structural schematic diagram of the screw 4 shown clearly shows the design features of the screw 4. One end of the screw 4 is designed as a plane, and the other end is specially configured with an opening for electric batch locking. These openings have various shapes, including but not limited to straight, cross, Mi-shaped, hexagonal and triangular. In this application, we will take the Mi-shaped opening as an example for detailed description. If the Mi-shaped screw 4 is not arranged in an orderly manner in a certain direction or is not arranged in a certain length and thickness during the assembly process, it may lead to a reduction in production efficiency during the actual production and assembly process, and may even cause mechanical failure or product quality problems. In order for the screw 4 assembly device 5 to use the screw 4 smoothly, the screw 4 provided by the screw 4 feeding device needs to ensure that the screw 4 is in the correct direction, with the flat end facing down and the open end facing up. Therefore, the feeding bin 21 needs to have the function of identifying the direction of the screw 4.

[0059] During the process of assembling the screw rods 4 by the assembling device 5, if there is no device of the present application to arrange the screw rods 4 in an orderly manner, the conveying of the screw rods 4 will become chaotic, seriously affecting the assembly efficiency and accuracy.

[0060] For this reason, Figure 1 As shown, in order to solve the problem that the existing screw 4 feeding device cannot arrange the screws 4 in an orderly manner and at the same time convey different types of screws 4 to the assembly equipment 5, the present application makes improvements to the existing screw 4 feeding transportation device. Specifically, the present application is an automatic conveying device 3 for screw 4 feeding, comprising: a support frame 1 and at least one automatic feeding device 2 fixed to the support frame 1 and a conveying device 3 connected to the automatic feeding device 2, wherein:

[0061] The automatic feeding device 2 includes a feeding bin 21 and a feeding assembly 22. The feeding assembly 22 is used to arrange the screws 4 in the feeding bin 21 in a consistent direction and convey them to the conveying device 3. The automatic feeding device 2 screens and orients the screws 4 in the feeding bin 21 to ensure the consistency and accuracy of the screws 4 during the conveying process. The conveying device 3 includes at least one conveying pipe 31 and a manifold 32 connected to the output end of the conveying pipe 31. The input end of the conveying pipe 31 is connected to the automatic feeding device 2 to convey the screws 4 arranged in the feeding assembly 22 to the manifold 32. The manifold 32 includes an inlet hole 321 and an output pipe 322. The inlet hole 321 is connected to the conveying pipe 31. The output pipe 322 is used to convey the screws 4 conveyed from the conveying pipe 31 to the manifold 32 to the assembly device 5. The assembly device 5 is used to assemble screws 4 of different models or screws 4 of the same model.

[0062] Specifically, the working principles of the automatic feeding device 2 and the conveying device 3 connected to the automatic feeding device 2 are as follows:

[0063] First, the screws 4 in the feeding bin 21 are screened and oriented by the feeding assembly 22 to ensure that all the screws 4 are in the same direction, thereby eliminating the confusion and disorder of the screws 4 during the conveying process. This step not only improves the efficiency of the screw 4 conveying, but also significantly reduces the assembly error rate caused by the inconsistent direction of the screw 4. Subsequently, the oriented and arranged screws 4 are fed into the conveying device 3 in an orderly manner. The conveying device 3 is composed of at least one conveying pipe 31, which are independent of each other or interconnected to meet the conveying requirements of screws 4 of different models or quantities. The interior of the conveying pipe 31 is designed with a smooth conveying surface to reduce the friction and resistance of the screw 4 during the conveying process, ensuring that the screw 4 can move forward smoothly and quickly.

[0064] When the screw rods 4 pass through the delivery pipe 31 and reach the confluence piece 32, they are further integrated and prepared to be delivered to the assembly device 5. The confluence piece 32 is a transition part 123 between the delivery device 3 and the assembly device 5, and its design is exquisite and its structure is compact. The inlet hole 321 is tightly connected to the delivery pipe 31 to ensure that the screw rods 4 can seamlessly transition to the inside of the confluence piece 32. At the same time, the guide structure inside the confluence piece 32 can guide the screw rods 4 to flow in a predetermined direction to avoid collision or blockage during the confluence process.

[0065] Finally, the screw rods 4 arranged by the manifold 32 are accurately transported to the assembly device 5 through the output tube 322. The assembly device 5 automatically selects and grabs the corresponding type of screw rods 4 for assembly according to production requirements. Since the screw rods 4 have been orderly arranged and accurately transported during the transportation process, the assembly process becomes more efficient, accurate and reliable.

[0066] In addition, the automatic conveying device 3 of the present application is also highly scalable and flexible. By adjusting the number and layout of the automatic feeding device 2 and the conveying device 3, it is easy to adapt to the conveying requirements of screws 4 of different sizes and models. At the same time, the device also supports seamless connection with other automated equipment, such as automated assembly lines, automated testing equipment, etc., thereby realizing the automation and intelligence of the entire production process. Example 2

[0067] like Figure 1-3 As shown, what is different from Example 1 is that: in order to improve the conveying capacity of the automated conveying device 3 for feeding the screw 4 of the present application to achieve the conveying capacity of different types of screws 4 that match the assembly method of the assembly equipment 5 for the purpose, further, the support frame 1 in the automated conveying device 3 for feeding the screw 4 of the present application includes a base 11 and a main body 12 arranged on the base 11, and the main body 12 includes a first fixed frame 121 and a second fixed frame 122 connected by a transition portion 123; wherein the base 11 serves as a support for the entire device, alleviates shaking during transportation, and improves the transportation efficiency of the device.

[0068] Furthermore, at least one mounting plate 1211 is fixed in the first fixing frame 121, and the mounting plate 1211 is used to fix the automatic feeding device 2, and the automatic feeding device 2 is arranged in sequence along the length direction of the mounting plate 1211; wherein the automatic feeding device 2 can be arranged in sequence on a mounting plate 1211 according to the length specifications of the screw rod 4 stored therein from large to small; at the same time, the present application is not limited to the design that the first fixing frame 121 only fixes a single mounting plate 1211; each different mounting plate 1211 can be independently assembled with an automatic feeding device 2 of different models (specifically involving materials, assembly positions, etc., not limited to length differences). On the same mounting plate 1211, screw rods 4 of the same specifications but different lengths can be reasonably distributed. This design innovatively realizes the precise transportation of screw rods 4 of specified models and lengths by accurately positioning the coordinates of each automatic feeding device 2 under the control of an external control system.

[0069] Furthermore, the second fixing frame 122 is used to fix the collector 32, and the projections of the first fixing frame 121 and the second fixing frame 122 in the height direction are parallel, and the distance between the projections of the first fixing frame 121 and the second fixing frame 122 in the height direction is the length of the transition portion 123. The above technical solution ensures the structural coordination and consistency of the first fixing frame 121 and the second fixing frame 122. The projection distance between the two in the height direction is exactly equal to the length of the transition portion 123. This design ensures that there is sufficient space for placing multiple (at least one in this application) conveying pipes 31 between the automatic feeding device 2 and the collector 32. At the same time, this design also reduces unnecessary space occupation and provides convenience for subsequent maintenance and maintenance work.

[0070] Furthermore, the collector 32 is provided with a collector groove 323 on one side along the thickness direction of the collector 32, and a cover plate 324 on the other side, and the cover plate 324 is fixed to the collector 32 by screws 325, wherein the cover plate 324 is fixed to one side of the collector 32 by screws 325, which not only plays a role of sealing and protection, but also can reduce the influence of external factors on the conveying process of the screw 4 inside the collector 32 to a certain extent. This design makes the entire conveying device 3 more compact and durable, and can operate stably in various complex working environments.

[0071] Further, the confluence groove 323 is connected with the inlet hole 321; a plurality of branch grooves 3231 are also provided on both sides of the confluence groove 323, and the branch grooves 3231 are all connected with the inlet hole 321; the side of the confluence groove 323 away from the inlet hole 321 is connected with the output pipe 322. Through the design of the confluence groove 323 in the confluence piece 32 and the layout of the branch grooves 3231, the automatic conveying device 3 of the present application can further optimize the conveying process of the screw 4. Specifically, when the screw 4 enters the confluence piece 32 from the conveying pipe 31, they first enter the confluence groove 323, which serves as a collection and temporary storage area for the screw 4. The design of the confluence groove 323 ensures that the screw 4 can smoothly transition here, reducing the loss caused by direct impact or collision. At the same time, a plurality of branch grooves 3231 are provided on both sides of the confluence groove 323, and these branch grooves 3231 are connected with the inlet hole 321, providing more conveying path options for the screw 4. Such a design not only improves the conveying flexibility of the screw 4, but also can balance the number of screws 4 on each conveying path to a certain extent, thereby avoiding blockage or failure of certain paths due to excessive load.

[0072] Furthermore, in the confluence groove 323, the screw 4 will continue to move forward according to the preset path and speed until it reaches the side of the confluence groove 323 away from the inlet hole 321. At this time, the screw 4 has completed the transition from the delivery pipe 31 to the confluence groove 323 and is ready to enter the final output pipe 322. As the end point of the screw 4 delivery, the output pipe 322 is also designed to focus on stability and smoothness. The output pipe 322 is connected to the confluence groove 323 to ensure that the screw 4 can enter smoothly and continue to be transported forward. At the other end of the output pipe 322, the screw 4 will be accurately transported to the assembly equipment 5 to complete the entire delivery process.

[0073] Furthermore, a first control device 326 for controlling the conduction of the confluence groove 323 is provided on one side of the confluence member 32; the first control device 326 includes a first cylinder 3261 fixed to the confluence member 32 and a slider 3262 driven by the cylinder, the slider 3262 is provided with a blocking portion 3263, and the cylinder drives the slider 3262 to drive the blocking portion 3263 to block the confluence groove 323 from passing through. The first control device 326 can realize effective control of the conveying process of the screw 4.

[0074] Furthermore, a first optical fiber 3264 is installed above the end of the slider 3262 corresponding to the bottom of the confluence groove 323. The first optical fiber 3264 is used to detect the number of screws 4 that fall on the slider 3262 during the process of transporting the screw 4 in the confluence groove 323. Specifically, when the number of screws 4 that fall on the slider 3262 detected by the first optical fiber 3264 reaches a certain level, the first optical fiber 3264 will immediately send a signal to the control system, and the control system will then start the first cylinder 3261 in the first control device 326. The first cylinder 3261 responds quickly, driving the slider 3262 and the blocking portion 3263 thereon to move forward, accurately blocking the through portion of the confluence groove 323. This action effectively prevents subsequent screws 4 from continuing to enter the confluence groove 323, thereby avoiding the blockage problem caused by excessive accumulation of screws 4. At the same time, the control system will also intelligently adjust the feeding speed of the automatic feeding device 2 and the conveying efficiency of the conveying pipe 31 according to the received information on the number of screws 4, to ensure the balance and stability of the entire conveying process.

[0075] Furthermore, the confluence groove 323 is provided with at least one blowing groove 3232, and the blowing groove 3232 is located between the first control device 326 and the output pipe 322; the blowing groove 3232 and the blowing interface 3233 are connected, and the gas is blown into the confluence groove 323 through the blowing interface 3233 to blow the screw 4 between the first control device 326 and the output pipe 322 into the output pipe 322. This design effectively alleviates the problem of the screw 4 in the confluence piece 32 being blocked.

[0076] The rest is the same as in Example 1 and will not be described in detail herein.

[0077] like Figure 1-7 As shown, the difference from Example 1 is that: in order to further improve the accuracy and flexibility of the present application in sorting the screws 4, specifically, the automatic feeding device 2 also includes a base plate 23, and the feeding bin 21 and the feeding assembly 22 are both fixed to the base plate 23;

[0078] The feeding bin 21 includes: a front side plate 211, which is fixedly connected to the mounting plate 1211 on one side along its thickness direction and fixedly connected to the base plate 23 on one side along its length direction; a rear side plate 212, which is arranged parallel to the front side plate 211 and fixedly connected to the base plate 23 on one side along its thickness direction; a bottom plate 213, which is respectively fixedly connected to the front side plate 211 and the rear side plate 212 on both sides along its length direction and is spaced apart from the base plate 23 by a spacing groove.

[0079] Furthermore, the feeding assembly 22 includes a first feeding piece 221 and a second feeding piece 222; the first feeding piece 221 lifts the screw 4 in the feeding bin 21 through the spacing groove, and slides the screw 4 into the top of the second feeding piece 222; the second feeding piece 222 is used to push the screw 4 sliding into its top to the entrance of the conveying pipe 31, and the screw 4 is transported by the conveying pipe 31.

[0080] Specifically, it can be seen from the above technical solution that in the present application, the substrate 23 is installed on the mounting plate 1211, the substrate 23 forms an angle a with the vertical plane, the material bin forms an angle b with the horizontal plane, and the top surfaces of the first feeding member 221 and the second feeding member 222 form an angle c with the vertical plane of their front faces. In the present application, when the angle c is greater than the angle a, the top surfaces of the first feeding member 221 and the second feeding member 222 are tilted upward relative to the horizontal after installation, so that the screw 4 can lie on the top of the first feeding member 221 and the second feeding member 222 and be close to the substrate 23. When the first feeding member 221 descends to the bottom plate 213 and then rises again, the screw 4 in the feeding bin 21 that is parallel to the top surface of the push plate and close to the substrate 23 can be pushed up by the sliding push plate of the first feeding member 221. Due to the existence of the angle a, the screws 4 that are erected, tilted, and stacked in the material bin will automatically fall back into the material bin during the rising process of the sliding push plate of the first feeding member 221. When the sliding push plate of the first feeding member 221 is raised to the top and the sliding push plate of the second feeding member 222 is lowered to the bottom (as shown in the state), due to the existence of angle b, the screw 4 at the top of the sliding push plate of the first feeding member 221 can slide onto the top of the sliding push plate of the second feeding member 222. Figure 4 ) is blocked, and only one screw rod 4 can slide to the top of the sliding push plate of the second feeding member 222.

[0081] Furthermore, the substrate 23 is provided with a detection device 231 corresponding to the highest position of the second feeding member 222 in the length direction thereof, and the detection device 231 includes: a direction identification optical fiber 2311 for detecting the direction of the screw 4; a rotating stopper 2312, and the rotating stopper 2312 can make the end of the screw 4 flush with the top of the second feeding member 222;

[0082] The back-blowing device 2313 is electrically connected to the direction identification optical fiber 2311, and back-blown the screw 4 with arrangement position failure identified by the direction identification optical fiber 3211 back to the feeding bin 21. In the specific implementation process, the back-blowing device 2313 also includes a back-blowing mechanism that cooperates with the direction identification optical fiber 2311 to realize the back-blowing of the screw 4 with arrangement position failure back to the feeding bin 21; the back-blowing mechanism specifically includes a blowing hole and a blowing interface 3233 connected to the back-blowing hole, and blowing air from the blowing interface 3233 can blow the screw 4 located on the sliding push plate of the first feeding member 221 down from the side, drop it onto the return guide sheet fixed on the top of the rear side plate 212, and slide along the guide sheet back to the chamber of the feeding bin 21.

[0083] Furthermore, the above mechanism can accurately identify the screw 4 with incorrect direction, and blow it back to the feed bin 21 through high-pressure gas or mechanical device, so as to ensure that only the screw 4 with the correct direction is sent to the subsequent conveying process. This design not only improves the accuracy of the arrangement of the screw 4, but also reduces the production failure and waste caused by the wrong direction. In addition, in order to further improve the intelligence level of the conveying device 3, the present application also introduces an intelligent control system. The system can monitor various parameters in the conveying process, such as the number, speed, position, etc. of the screw 4 in real time, and automatically adjust the working state of the conveying device 3 according to the preset algorithm. For example, when the system detects that there are too many screws 4 on a certain conveying path, it will automatically adjust the conveying speed of other paths to achieve load balancing; when it is detected that the direction of the screw 4 is wrong, the backblowing device 2313 will be immediately triggered to correct it. This intelligent control method not only improves the conveying efficiency, but also greatly reduces the need for manual intervention.

[0084] Furthermore, a full-fill sensing optical fiber 311 and a blocking device 312 electrically connected to the full-fill sensing optical fiber 311 are provided at the input end of the conveying tube 31; the full-fill sensing optical fiber 311 is used to detect whether there is already a screw 4 at the input end of the conveying tube 31; the blocking device 312 blocks other screws 4 from entering the input end of the conveying tube 31 after receiving the information that the input end of the full-fill sensing optical fiber 311 is full of material transmitted by the full-fill sensing optical fiber 311.

[0085] In the specific implementation process, the blocking device 312 includes a blocking electromagnet and a pressing electromagnet to achieve its blocking effect. When the blocking electromagnet is not energized, it can block the input end of the conveying pipe 31 through the opening on the wall of the conveying pipe 31; when the blocking electromagnet is energized, the iron core retracts to make the conveying pipe 31 unobstructed. When the pressing electromagnet is not energized, its iron core does not contact the screw 4 in the conveying pipe 31. When energized, its iron core extends out and can press the second screw 4 near the outlet in the conveying pipe 31. At the same time, there are multiple installation positions on the electromagnet mounting seat, and there are multiple openings on the wall of the conveying pipe 31. The pressing electromagnet can be installed in different positions to adapt to screws 4 of different lengths and specifications, so that it can press the second screw 4 in the conveying pipe 31.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
