[0001] This utility model relates to the field of automatic feeding technology, and in particular to an automatic feeding device for fasteners. Background Technology

[0002] An automatic fastener feeding device is a piece of equipment that can automatically complete the fastener feeding operation. It is mostly used in the assembly process of industrial production. It consists of a storage, conveying, separation and orientation, and detection and control mechanism. It can orderly deliver screws and nuts from the storage point to the assembly position through the conveying mechanism. The separation and orientation mechanism ensures that they are arranged in a specific direction, and the detection and control mechanism ensures that the whole process is accurate and stable, which can improve production efficiency and reduce labor costs.

[0003] Automatic fastener feeding devices are designed and optimized for specific specifications and types of fasteners, but their compatibility with fasteners of different sizes, shapes, and materials is limited. They need to handle fasteners of various specifications, requiring frequent replacement of feeding tracks and sorting mechanism components. The adjustment process is complex and time-consuming, sometimes even necessitating redesign and modification of the equipment. When facing small-batch, multi-variety production tasks, the advantages of automatic feeding devices are difficult to fully realize because frequent product model changes require extensive parameter adjustments and settings, leading to long production preparation times and reduced production efficiency. They are less flexible than manual feeding. Existing technologies have designed feed track modules that can be quickly replaced, but in actual use, frequent feed track replacements during production still require time, further reducing production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic fastener feeding device, which aims to improve the problem of reduced production efficiency caused by the need for frequent changes of the feeding track during production and the time required for quick changes of the feeding track.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic fastener feeding device, including a fixed frame, a feeding box provided on the front side of the fixed frame, slide rails fixedly connected to the left and right sides of the inside of the feeding box, sliders slidably connected between adjacent slide rails, a feeding plate fixedly connected between adjacent sliders, a fixed plate fixedly connected to the bottom of the inside of the feeding box, a multi-stage telescopic rod fixedly connected to the top of the fixed plate, a diagonal support frame fixedly connected to the top of the fixed frame, a clamping plate provided inside the diagonal support frame, a bolt threadedly connected to the left side of the diagonal support frame, a discharge port opened on the right side of the diagonal support frame, and an installation mechanism provided on the front side of the fixed frame for fixing the feeding box.

[0006] As a further description of the above technical solution:

[0007] The installation mechanism includes a connecting block, the front side of which is fixedly connected to the rear side of the feeding box. The front side of the fixing frame has a groove. The right side of both the fixing frame and the connecting block has two round holes. The inside of each of the two round holes is fixedly connected to a connecting rod. The top left and right sides of the outer walls of the two connecting rods have slots. The inside of each of the slots is slidably connected to a locking strip.

[0008] As a further description of the above technical solution:

[0009] Each of the two adjacent slide rails is fixedly connected to a baffle at its top, and both baffles are of a smooth design.

[0010] As a further description of the above technical solution:

[0011] The four corners of the bottom of the fixed frame are all fixedly connected to support columns, and the bottoms of the multiple support columns are all fixedly connected to anti-slip sleeves.

[0012] As a further description of the above technical solution:

[0013] A connecting plate is fixedly connected to the top of each of the two card strips, and a pull ring is fixedly connected to the top of each of the two connecting plates.

[0014] As a further description of the above technical solution:

[0015] The bottom of the feeding box is fixedly connected to a cover plate, and a handle is fixedly connected to the bottom front side of the cover plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when encountering fasteners of different specifications, the size of the clamp can be adjusted by adjusting the bolt on the left side of the diagonal brace. After loosening the bolt, the clamp is moved to a suitable position, which is determined according to the actual size of the fastener. Then, the bolt is tightened to fix the clamp. At this time, the size of the clamp is adapted to the current fastener and will slide out from the discharge port on the right side of the diagonal brace, thereby realizing precise adjustment of fasteners of different specifications and improving production efficiency.

[0022] 2. In this utility model, when the feeding box is to be connected to the fixed frame, the connecting block is inserted into the groove on the front side of the fixed frame.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 and Figure 4This utility model provides an embodiment of an automatic fastener feeding device, including a fixed frame 1. A feeding box 3 is provided on the front side of the fixed frame 1 for storing fasteners. Slide rails 4 are fixedly connected to the left and right sides of the inside of the feeding box 3. Sliding sliders 5 are slidably connected between adjacent slide rails 4, allowing the sliders 5 to slide on the slide rails 4. A loading plate 6 is fixedly connected between adjacent sliding sliders 5. A fixed plate 7 is fixedly connected to the bottom inner side of the feeding box 3. A multi-stage telescopic rod 8 is fixedly connected to the top of the fixed plate 7. The multi-stage telescopic rod 8 extends and retracts, pushing the loading plate 6 to slide on the slide rails 4 via the sliders 5. When the loading plate 6 slides down, the fasteners... The material will flow into the loading plate 6. The top of the fixed frame 1 is fixedly connected to the inclined support frame 9, which is higher on the left than on the right. The inside of the inclined support frame 9 is provided with a clamping plate 10, which forms a groove 201 with the inclined support frame 9. The fastener will enter the groove 201 and be stuck on the top of the clamping plate 10 and the inclined support frame 9. The left side of the inclined support frame 9 is threaded with a bolt 11. By moving the clamping plate 10 to a suitable position and tightening the bolt 11, the size of the clamping opening can be adjusted according to the size of the fastener. The right side of the inclined support frame 9 is provided with a discharge port 12, from which the fastener slides out. The front side of the fixed frame 1 is provided with an installation mechanism 2, which is used to fix the feeding box 3.

[0032] Specifically, on the front side of the mounting bracket 1, there is a dedicated storage box 3 for storing firmware. Slide rails 4 are fixedly installed on both the left and right sides inside the storage box 3. These two slide rails 4 provide a sliding track for the slider 5, allowing the slider 5 to slide freely on the slide rails 4. A loading plate 6 is fixedly connected between the two sliders 5. A mounting plate 7 is also fixedly connected to the bottom inner side of the storage box 3, and a multi-stage telescopic rod 8 is installed on its top. When the multi-stage telescopic rod 8 extends or retracts, it pushes the loading plate 6 to slide on the slide rails 4 with the help of the slider 5. When the loading plate 6 slides down, the firmware will flow into the loading plate 6. At the top of component 1, a diagonal brace 9, which is higher on the left than on the right, is fixedly connected. Inside the diagonal brace 9, there is a clamping plate 10. The clamping plate 10 and the diagonal brace 9 together form a groove 201. The incoming fasteners will enter the groove 201 and be stuck on the top of the clamping plate 10 and the diagonal brace 9. The left side of the diagonal brace 9 is connected to a bolt 11 by a thread. By moving the clamping plate 10 to a suitable position and then tightening the bolt 11, the size of the clamping opening can be flexibly adjusted according to the size of the fastener. The right side of the diagonal brace 9 has a discharge port 12. The fasteners that have been adjusted and fixed will slide out smoothly from here so that they can enter the subsequent processing process.

[0033] Reference Figure 5The installation mechanism 2 includes a connecting block 202. The front side of the connecting block 202 is fixedly connected to the rear side of the feeding box 3. The front side of the fixing frame 1 has a groove 201. The connecting block 202 can be inserted into the groove 201. The right side of the fixing frame 1 and the connecting block 202 each has two round holes 203. The round holes 203 penetrate the fixing frame 1 and the connecting block 202. The inside of the two round holes 203 is fixedly connected to the connecting rod 204. The top left and right sides of the outer wall of the two connecting rods 204 each have a slot 205. The inside of the multiple slots 205 is slidably connected to the locking strip 206. The connecting rod 204 is inserted into the round hole 203 on the right side of the fixing frame 1 and the connecting block 202. The locking strip 206 is inserted into the slot 205 at the top of the two connecting rods 204 to lock them in place.

[0034] Specifically, the front side of the connecting block 202 is fixed to the rear side of the feeding box 3, while the front side of the fixing frame 1 is pre-grooved with a groove 201, into which the connecting block 202 can be precisely inserted, thus initially achieving the positioning connection between the two. To further stabilize the connection, two round holes 203 are opened on the right side of both the fixing frame 1 and the connecting block 202. The round holes 203 penetrate through these two components, and the connecting rod 204 is fixed in the two round holes 203 respectively. On the top left and right sides of the outer wall of the connecting rod 204, there are slots 205. The locking strip 206 is slid into the multiple slots 205 for locking, so that there will be no loosening, displacement or other issues affecting operation.

[0035] Reference Figure 1 and Figure 2 Each of the two adjacent slide rails 4 is fixedly connected to a baffle 13 at the top. Both baffles 13 are rounded to prevent the slider 5 from sliding out of the slide rail 4. Each of the four corners at the bottom of the fixing frame 1 is fixedly connected to a support column 14. Each of the support columns 14 is fixedly connected to an anti-slip sleeve 15 at the bottom to prevent the device from moving. Each of the two clips 206 is fixedly connected to a connecting plate 16 at the top. Each of the two connecting plates 16 is fixedly connected to a pull ring 17 at the top to facilitate pulling the clips 206.

[0036] Specifically, baffles 13 are fixedly connected to the top of both slide rails 4. The baffles 13 have a smooth design and can effectively prevent the slider 5 from sliding out of the slide rail 4. Support columns 14 are firmly fixed at the four corners of the bottom of the fixing frame 1. The bottom of the support columns 14 is connected to anti-slip sleeves 15 to prevent the device from moving during operation. The tops of the two locking strips 206 are connected to connecting plates 16, and the top of each connecting plate 16 has a pull ring 17, which makes it convenient for the operator to pull the locking strips 206, making the operation process more convenient and efficient.

[0037] Reference Figure 2 and Figure 3The bottom of the material box 3 is fixedly connected to a cover plate 18. The bottom front side of the cover plate 18 is fixedly connected to a handle 19 for easy opening and removal of the fastener. The rear side of the cover plate 18 is fixedly connected to two hinges 20. The top of the two hinges 20 is fixedly connected to the bottom rear side of the material box 3 for easy opening and closing of the cover plate 18. The bottom front side of the material box 3 is fixedly connected to a buckle fastener 21. The bottom front side of the cover plate 18 is fixedly connected to a pipe clamp 22 for fixing the cover plate 18.

[0038] Specifically, the bottom of the material box 3 is equipped with a practical cover plate 18. For easy operation, a handle 19 is installed on the front bottom of the cover plate 18, which allows the operator to easily pull open the cover plate 18 and remove the fastener. The rear side of the cover plate 18 is connected to two hinges 20. The top of the hinges 20 is fixed to the rear bottom of the material box 3 to ensure that the cover plate 18 can open and close smoothly. The front bottom of the material box 3 is provided with a buckle fastener 21, and the front bottom of the cover plate 18 is equipped with a pipe clamp 22. The two work together to effectively fix the cover plate 18 and prevent it from opening accidentally.

[0039] Working principle: A feeding box 3 is fixed to the front of the fixed frame 1. When the device starts working, the multi-stage telescopic rod 8 at the top of the fixed plate 7 extends and retracts. When the multi-stage telescopic rod 8 extends, it pushes the feeding plate 6 to slide upward along the slide rail 4 with the help of the slider 5. At this time, the feeding plate 6 is in a higher position, waiting to receive the fasteners put in from above. When it is necessary to send the fasteners out of the feeding box 3, the multi-stage telescopic rod 8 shortens, the feeding plate 6 slides down, and the fasteners originally placed in the feeding box 3 will flow into the feeding plate 6. After the fasteners flow into the feeding plate 6, they will be conveyed to the inclined support frame 9 at the top of the fixed frame 1. The inclined support frame 9 is in the shape of being higher on the left and lower on the right. The internal clamping plate 10 and the inclined support frame 9 together form a groove 201. When the fasteners on the loading plate 6 are fed to the inclined support frame 9, they will slide into the groove 201 due to gravity and the tilt angle of the inclined support frame 9, and get stuck on the top of the clamping plate 10 and the inclined support frame 9. When encountering fasteners of different specifications, the clamping size can be adjusted by adjusting the bolt 11 on the left side of the inclined support frame 9. After loosening the bolt 11, move the clamping plate 10 to a suitable position, which is determined according to the actual size of the fastener. Then tighten the bolt 11 to fix the clamping plate 10. At this time, the clamping size is adapted to the current fastener. After adjustment and fixation, the fastener will slide out from the discharge port 12 on the right side of the inclined support frame 9 and smoothly enter the subsequent processing flow, thereby realizing the feeding and precise adjustment of fasteners of different specifications.

[0040] Furthermore, when connecting the feeding box 3 to the fixed frame 1, the connecting block 202 precisely engages with the groove 201 on the front side of the fixed frame 1. This initial positioning step determines the position of the feeding box 3 on the fixed frame 1, ensuring that the relative positions of the two in the horizontal direction are accurate. On the right side of both the fixed frame 1 and the connecting block 202, there are two through round holes 203. The connecting rod 204 is inserted into these round holes 203 to further fix the two in the horizontal direction, restricting the relative movement in the left and right directions. The top left and right sides of the outer wall of the connecting rod 204 have slots 205. By sliding the locking strip 206 into the slots 205, the vertical locking is achieved. This locking action prevents the fixed frame 1 and the feeding box 3 from separating or shifting in the vertical direction. The feeding box 3 and the fixed frame 1 are stably connected. During the operation of the device, failures caused by loose connections or displacement are effectively avoided, ensuring the stable operation of the entire device.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
