[0038] See also Figures 1 to 5 The embodiment of the present invention provides a spring sorting device, which is used in an automated assembly system involving spring assembly to achieve the purpose of automatic spring sorting. The spring sorting device includes a frame 10, a silo 20, a material taking mechanism 30 and a screening mechanism 40.

[0039] The frame 10 is a mounting carrier for the silo 20, the screening mechanism 40 and the material taking mechanism 30, and mainly plays a supporting role. The frame 10 includes a base 11, a first support member 12, a second support member 13 and a third support member 14. The base 11 is arranged horizontally or approximately in a horizontal direction. The base 11 can be a plate-like member or a frame structure. For example, the base 11 is a rectangular plate structure. The first support member 12 is relatively arranged on the edge of one side of the base 11, and the second support member 13 is relatively arranged on the edge of the other side of the base 11. The base 11, the first support member 12 and the second support member 13 are enclosed together to form a three-dimensional support frame.

[0040] The first support member 12 , the second support member 13 and the third support member 14 are all profiles.

[0041] The silo 20 is provided on the frame 10 for storing the springs to be sorted. The silo 20 is a funnel-shaped structure, with a feeding port formed at the top of the silo 20 and a material removal port 21 formed at the bottom of the silo 20, which is arranged opposite to the feeding port.

[0042] Among them, the silo 20 can be fixed on the frame 10 by a support or a mounting component, the mounting component may include a mounting plate and a support plate, the mounting plate is fixed to the second support member 13 by bolts, screws and other structures, the support plate is fixed to the mounting plate by bolts, screws and other structures, and a mounting groove for installing the silo 20 is set on the mounting plate, and the silo 20 is installed in the mounting groove of the support plate.

[0043] The material picking mechanism 30 includes a material picking drive assembly 31, a material picking assembly 32 and a material channel assembly 33. The material picking assembly 32 extends into the interior of the silo 20 from the material picking port 21. The material channel assembly 33 is arranged on one side of the material picking assembly 32 and cooperates with the material picking assembly 32 to pick up materials. The material picking drive assembly 31 is arranged on the frame 10, and is used to drive the material picking assembly 32 to rotate to pick up materials, that is, the material picking assembly 32 can move in a circle under the action of the material picking drive assembly 31, and pick up the springs to be sorted stored in the silo 20 to the material channel assembly 33.

[0044] The screening mechanism 40 includes a screening component 41 and a feed pipe 42. The screening component 41 is rotatably disposed on the frame 10 and is suitable for switching between a first position and a second position. When in the first position, the screening component 41 is connected to the discharge port of the material channel component 33. At this time, spring screening can be performed normally, so that the screened qualified products enter the feed pipe 42; when in the second position, the screening component 41 is tilted downward to move away from the material channel component 33. At this time, the defective products screened out by the screening component 41 can be collected.

[0045] It can be understood that the spring sorting device provided in the embodiment of the present invention is provided by arranging a material bin 20, a material picking mechanism 30 and a screening mechanism 40 on the frame 10. The material picking mechanism 30 includes a material picking drive assembly 31, a material picking assembly 32 and a material channel assembly 33. The material picking assembly 32 extends into the interior of the material bin 20 from the material picking port 21. The material channel assembly 33 is arranged on one side of the material picking assembly 32 and cooperates with the material picking assembly 32 to pick up materials. The material picking drive assembly 31 is arranged on the frame 10, and is used to drive the material picking assembly 32 to rotate to pick up materials.

[0046] Furthermore, the screening mechanism 40 includes a screening component 41 and a feeding pipe 42. The screening component 41 is rotatably arranged on the frame 10 and is suitable for switching between a first position and a second position. When in the first position, the screening component 41 is connected to the discharge port of the material channel component 33. At this time, the spring screening can be performed normally, so that the screened qualified products enter the feeding pipe 42. When in the second position, the screening component 41 tilts downward to be away from the material channel component 33, and the defective products screened out by the screening component 41 can be collected. In this way, by improving the structure of the material taking mechanism 30 and the screening mechanism 40 to replace the flexible vibration disk or centrifuge and other equipment in the related technology, it can not only reduce the production cost of the device and simplify the control process, but also reduce the volume of the device and improve the space utilization rate of the device.

[0047] Continue reading Figure 3 and Figure 4 In some embodiments of the present invention, the material taking assembly 32 includes a material taking ring 321 and at least one magnetic member 322 . The material taking ring 321 extends from the material taking port 21 into the interior of the silo 20 , and the magnetic member 322 is arranged on the material taking ring 321 .

[0048] When the picking ring 321 moves in a circle under the action of the picking drive assembly 31, the magnetic part 322 on the picking ring 321 rotates synchronously. When the magnetic part 322 rotates to the inside of the silo 20, it adsorbs the spring in the silo 20, and then drives the adsorbed spring to rotate with the picking ring 321 to the position of the material channel assembly 33 for interception, thereby realizing the transfer of the spring from the silo 20 to the material channel assembly 33.

[0049] In the embodiment of the present invention, at least one magnetic member 322 is arranged on the material taking ring 321. The magnetic member 322 takes out the spring stored in the silo 20 and feeds it into the material channel assembly 33 through its own magnetic force. When one magnetic member 322 is arranged on the material taking ring 321, it is equivalent to the material taking ring 321 rotating one circle to complete one material taking. When multiple magnetic members 322 are arranged on the material taking ring 321, the multiple magnetic members 322 are arranged in an array along the circumferential direction of the material taking ring 321, which is equivalent to the material taking ring 321 rotating one circle, and multiple material taking can be completed synchronously.

[0050] The magnetic part 322 can be a permanent magnet or an electromagnet. When the magnetic part 322 is a permanent magnet, the permanent magnet is a columnar structure and can be embedded in the feeding ring 321, that is, a receiving groove is opened in the feeding ring 321, and the permanent magnet is interference fit in the receiving groove.

[0051] In addition, a material taking claw and other structures can be provided on the material taking ring 321, so that when the material taking claw moves with the material taking ring 321, the spring stored in the material bin 20 can be grabbed into the material channel assembly 33. That is, when the material taking claw rotates into the material bin 20 with the material taking ring 321, the material taking claw grabs the spring, and when the material taking claw rotates to the position of the material channel assembly 33 with the material taking ring 321, the material taking claw releases the spring to make it fall into the material channel assembly 33. Among them, the material taking claw is equivalent to a micro-manipulator structure.

[0052] Continue reading Figure 3 and Figure 4 In some embodiments of the present invention, the material picking drive assembly 31 includes a gear 311, a rack 312 and a material picking drive cylinder 313. The gear 311 is coaxially arranged with the material picking ring 321. The rack 312 is guided on the frame 10. The rack 312 is meshed with the gear 311. The material picking drive cylinder 313 is arranged on the frame 10. The output end of the material picking drive cylinder 313 is connected to the rack 312 for driving the rack 312 to perform linear reciprocating motion.

[0053] Specifically, to ensure the stable rotation of the material picking ring 321, the gear 311 is nested on the gear rotating shaft 316 through a flange bearing, the gear rotating shaft 316 is mounted on the mounting base plate 317, the mounting base plate 317 is fixed on the frame 10, and the rack 312 is fixed on the rack mounting plate 318. The material picking drive cylinder 313 is mounted on the cylinder drive seat 319, and the cylinder drive seat 319 is mounted on the mounting base plate 317.

[0054] A linear guide 314 is provided on one of the mounting substrate 317 and the rack mounting plate 318, and a slider 315 is provided on the other of the mounting substrate 317 and the rack mounting plate 318, and the linear guide 314 and the slider 315 are slidably matched. For example, the linear guide 314 is provided on the mounting substrate 317, and the slider 315 is provided on the rack mounting plate 318.

[0055] When the material picking drive cylinder 313 works to perform linear reciprocating motion, it drives the rack mounting plate 318 to perform linear reciprocating motion along the linear guide rail 314, so that the rack 312 and the gear 311 engage to produce relative motion, and then drives the material picking ring 321 to perform circular motion along the gear rotating shaft 316 to achieve the purpose of material picking.

[0056] Continue reading Figure 3 and Figure 4In some embodiments of the present invention, the channel assembly 33 includes a channel body 331, which is obliquely mounted on the above-mentioned mounting substrate 317. The channel body 331 is a sheet metal part, and the channel is constructed inside the channel body 331 along its length direction, that is, the channel is formed by bending the sheet metal part. A material blocking port 3311 is provided on the channel body 331, and the material blocking port 3311 allows the material taking ring 321 to pass through, and can intercept the spring adsorbed on the material taking ring 321, so that the spring can smoothly enter the channel to take the material.

[0057] In the embodiment of the present invention, the blocking opening 3311 is equivalent to a notch provided on the material channel body 331, that is, a notch is provided on the side of the material channel body 331 facing the material taking ring 321, through which the material taking ring 321 can pass. When the magnetic member 322 attracts the spring and passes through the notch, the spring is intercepted by the material channel body 331, and only the material taking ring 321 is allowed to pass through the notch.

[0058] In some embodiments of the present invention, the material channel assembly 33 also includes a first material stopper 332 and a second material stopper 333, which are relatively arranged on one side of the material channel body 331, and the material blocking opening 3311 is formed by the gap between the first material stopper 332 and the second material stopper 333.

[0059] Equivalently, the material blocking opening 3311 is a gap between the material blocking members additionally arranged on the material channel body 331, that is, a gap is formed between the first material blocking member 332 and the second material blocking member 333, which can not only ensure the passage of the material taking ring 321, but also intercept the spring adsorbed on the material taking ring 321, so that the spring can smoothly enter the material channel. When the magnetic member 322 adsorbs the spring through this gap, the spring is intercepted by the first material blocking member 332 or the second material blocking member 333 and falls on the material channel body 331.

[0060] Continue reading Figure 3 and Figure 4 In some embodiments of the present invention, in order to prevent the spring that enters the material channel from the material blocking port 3311 from popping out of the material channel, the material channel assembly 33 also includes a third material stopper 334, which is relatively arranged on both sides of the material channel body 331 to increase the depth of the material channel and prevent the spring from popping out of the material channel.

[0061] Figure 6 Schematic diagram of the structure of the screening mechanism 40 in the spring sorting device provided in an embodiment of the present invention.

[0062] See also Figure 6In some embodiments of the present invention, the screening assembly 41 includes a screening body 411 and a screening drive cylinder 412, and the screening body 411 is also a sheet metal part. The inside of the screening body 411 is constructed with a screening channel along its length direction, and the screening body 411 is provided with a screening hole 4131, and the screening hole 4131 is connected to the screening channel. The screening hole 4131 allows only one spring to pass through at a time, and the spring that does not pass through the screening hole 4131 is intercepted in the screening channel. Therefore, the size of the screening hole 4131 is adapted to the spring.

[0063] The screening drive cylinder 412 is arranged on the frame 10, and the driving end of the screening drive cylinder 412 is rotatably connected to the screening body 411, and is used to drive the screening body 411 to switch between the first position and the second position. When in the first position, the screening body 411 is connected to the discharge port of the material channel assembly 33. At this time, spring screening can be carried out normally, so that the screened qualified products enter the conveying pipe 42; when in the second position, the screening body 411 tilts downward to move away from the material channel assembly 33, and the defective products screened out by the screening hole 4131 can be collected.

[0064] In some embodiments of the present invention, the screening component 41 further includes a screening plate 413 , which is fixed to the screening body 411 , and the screening holes 4131 are provided on the screening plate 413 .

[0065] In other words, the screening component 41 is composed of two parts: a screening body 411 and a screening plate 413. The screening plate 413 can be rotatably mounted on a mounting seat 417. The screening plate 413 is connected to the screening body 411 by fasteners such as screws.

[0066] Specifically, one end of the screening body 411 is connected to the screening plate 413, and the other end of the screening body 411 is connected to the cylinder adapter block through the flip shaft, and the cylinder adapter block is connected to the movable end of the screening drive cylinder 412, and the screening drive cylinder 412 is hinged to the cylinder mounting seat through the hinge shaft, and the cylinder mounting seat is fixed on the frame 10. The screening plate 413 is connected to the mounting seat 417 through the rotating shaft, and the mounting seat 417 is fixed on the frame 10.

[0067] Of course, the screening body 411 may also be an integrally formed groove-shaped structure, and the screening hole 4131 is provided on the end wall of the screening body 411 .

[0068] In some embodiments of the present invention, the screening component 41 further includes a blowing component 414. A material guide block 418 is provided at the end of the material delivery pipe 42. The blowing component 414 is connected to the material guide block 418 to supply air to the screening channel.

[0069] In the embodiment of the present invention, the air blowing assembly 414 is provided to supply air to the screening channel, so that the spring entering the material guide block 418 can smoothly enter the material delivery pipe 42 under the push of the high-pressure gas, thereby avoiding material blockage.

[0070] In some embodiments of the present invention, the screening assembly 41 further includes a blocking plate 415, which is disposed on the blowing assembly 414. When the screening driving cylinder 412 drives the screening body 411 to rotate to the first position, the blocking plate 415 covers the top of the screening channel to prevent the spring in the screening channel from popping out.

[0071] The blowing assembly 414 includes a blowing block and an air nozzle. The blowing block is connected to the material guide block 418. The air nozzle is connected to the blowing block. The air nozzle is connected to an external gas source capable of supplying high-pressure gas.

[0072] In some embodiments of the present invention, the screening assembly 41 further includes a material receiving box 416. The material receiving box 416 is a box body structure, and the material receiving box 416 is connected to the third support member 14 of the frame 10 through a hanging plate.

[0073] If the spring entering the screening body 411 can pass through the screening hole 4131, it will enter the material guide block 418, and under the push of the high-pressure gas, the screened spring will enter the material delivery pipe 42. If the spring entering the screening body 411 cannot pass through the screening hole 4131, it will be blocked inside the screening body 411. At this time, when the screening drive cylinder 412 works to perform linear reciprocating motion, it drives the cylinder adapter block to move, and then drives the screening body 411 to perform circular motion around the rotation axis, so that the screening body 411 is located in the second position, and the screening body 411 is tilted downward to move away from the material channel assembly 33. At this time, the defective products screened out by the screening hole 4131 can be poured into the receiving box 416 for collection.

[0074] In the case where the receiving box 416 is not provided, a movable cart may be placed under the frame 10 to collect defective products.

[0075] See also Figure 1 and Figure 2 In some embodiments of the present invention, in order to prevent the springs from scattering on the outside of the receiving box 416, a material blocking plate 419 is provided above the receiving box 416. The material blocking plate 419 can be provided around the receiving box 416 or on both sides of the receiving box 416 relatively.

[0076] Continue reading Figure 1 and Figure 2 In some embodiments of the present invention, the spring sorting device further includes a first material detection component 50 and a second material detection component 60.

[0077] The first material detection component 50 and the second material detection component 60 are both mounted on the frame 10 through a sensor mounting plate, and the first material detection component 50 and the second material detection component 60 are spaced apart on the material conveying pipe 42 for detecting the material condition in the material conveying pipe 42 .

[0078] When there is no spring in the feeding pipe 42 or the spring stock is insufficient, that is, the second material detection component 60 does not detect a signal, the upper material taking mechanism 30 starts to work, and the screening mechanism 40 works synchronously. The material taking mechanism 30 continues to take materials until the spring stock in the feeding pipe 42 reaches the position where the first material detection component 50 is located, that is, when the first material detection component 50 detects a signal, the material taking mechanism 30 and the screening mechanism 40 both stop working, and work in a cycle according to this logic.

[0079] It should be noted that there is a certain distance between the first material detection component 50 and the second material detection component 60. Under the above-mentioned material taking logic, there will always be sufficient springs in the material conveying pipe 42 for use by the rear-end assembly equipment.

[0080] The present invention also provides an assembly system, comprising any one of the spring sorting devices described.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
