Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of automatic sorting of parts, and particularly relates to an automatic sorting device and automatic sorting system for open structure parts. BACKGROUND
[0002] In the field of metal stamping processing, the opening size precision of U-shaped open structure parts directly affects the stability after assembly. Due to factors such as raw material thickness dispersion, cantilever length fluctuation of bending process, etc., such parts are prone to opening size out-of-tolerance (too large or too small) after stamping forming, leading to assembly looseness or inability to assemble, and causing customer complaints. The traditional solution is to rely on 100% manual inspection and sorting after die blanking, which has the following defects:
[0003] Low efficiency: manual sorting speed is difficult to match the high-speed stamping production rhythm, prolonging the production cycle;
[0004] High cost: additional sorting personnel need to be configured, increasing labor costs, and manual sorting error rate is high, which easily leads to unqualified products flowing into downstream processes or being delivered to customers;
[0005] Lack of automation: unable to form online linkage with die production, restricting the demand for intelligent manufacturing upgrade.
[0006] Therefore, a fully automatic sorting device is needed to realize online real-time sorting of opening size and improve production efficiency and product qualification rate. UTILITY MODEL CONTENTS
[0007] In view of the above technical problems existing in the prior art, the utility model provides an automatic sorting device and automatic sorting system for open structure parts, which realizes fully automatic sorting of open structure parts.
[0008] According to the first aspect of the utility model, an automatic sorting device for open structure parts is provided, which comprises a sorting rotary body. The open structure part is clamped and matched with the edge of the sorting rotary body through the clamping force of the opening part. During the rotation of the sorting rotary body, the open structure part is subjected to at least one sorting force which is opposite to the clamping force, so as to separate the open structure part with clamping force less than the sorting force from the sorting rotary body. The automatic sorting device uses the clamping force of the open structure part to fix the part, and the sorting force (which can be gravity, centrifugal force or external applied force) realizes dynamic sorting without manual intervention and without complex sensors or visual recognition. Only the balance of force is used for sorting, which reduces the equipment cost and maintenance difficulty.
[0009] In a specific embodiment, the edge thickness of the sorting rotary body is the standard opening width size of the open structure part. By physical size limitation, the parts with excessively large openings can be directly screened out.
[0010] In specific embodiments, the sorting rotary body is a vertically placed roller structure, the sorting force releasing mechanism is the body of the open structure part, and the sorting force is the gravity that the open structure part receives when rotating with the roller structure.

[0011] In specific embodiments, the sorting rotary body is a horizontally placed roller structure, and the sorting force releasing mechanism is a blowing structure directed at the bottom of the open structure part. Sorting is performed through the blowing structure, which can further improve the control of the sorting force.
[0012] According to a second aspect of the present application, an automatic sorting system for open structure parts is provided, which comprises the automatic sorting device described above, and further comprises a feeding mechanism and a receiving mechanism. The feeding mechanism is connected to the sorting rotary body, and the receiving mechanism comprises a qualified product receiving area and an unqualified product receiving area. The unqualified product receiving area corresponds to the open structure parts that are separated from the sorting rotary body due to the clamping force being less than the sorting force. The automatic sorting system can realize the full-process automation of discharging, sorting, and receiving, reducing manual handling.
[0013] In specific embodiments, the sorting rotary body changes the open structure part with the opening facing downward to the open structure part with the opening facing upward through rotation. The qualified product receiving area is arranged below the area after the bottom of the sorting rotary body in the rotation direction, and the unqualified product receiving area is arranged below the area before the bottom of the sorting rotary body in the rotation direction. By arranging the qualified product receiving area and the unqualified product receiving area, the classification of the sorted parts is ensured to be accurate, facilitating subsequent processing.
[0014] In specific embodiments, the automatic sorting device comprises a roller and a first driving mechanism. The first driving mechanism is connected to the roller, and the edge thickness of the roller matches the qualified opening size of the open structure part. The cooperation of the roller and the first driving mechanism ensures stable rotation of the roller, and the matching of the edge thickness and the opening width of the part further improves the sorting accuracy.
[0015] In specific embodiments, a poking device is further arranged above the qualified product receiving area. The poking device comprises a poking rod and a second driving mechanism. The second driving mechanism is connected to the poking rod to drive the rotation of the poking rod. The poking rod is in contact with the open structure part on the roller when rotating, and the clamping force of the open structure part on the roller is greater than the sorting force. The addition of the poking device ensures that the qualified parts are smoothly stripped from the roller and into the qualified product receiving area.
[0016] In specific embodiments, the poking rod is arranged in a pair, corresponding to the open structure parts on both sides of the roller, and the rotation direction of the poking rod is consistent with the rotation direction of the roller.

The feeding mechanism cooperates with the vibrating device to effectively arrange the parts, avoid stacking or jamming of the parts, provide stable feeding for the sorting process, and ensure overall operation efficiency.
[0018] In specific embodiments, a transmission mechanism is further arranged between the feeding mechanism and the automatic sorting device, the transmission mechanism transfers the open-structure parts on the feeding mechanism to the roller and clamps the open-structure parts to the edge of the roller. The addition of the transmission mechanism realizes automatic transfer of the parts from the feeding track to the sorting device.

[0022] The automatic sorting device of the utility model realizes automatic sorting of parts through the balance between clamping force and sorting force when the sorting rotary body rotates. This method discards traditional visual recognition and complex mechanical detection, reduces equipment cost, and greatly improves sorting efficiency. The sorting force can directly come from gravity or rotational inertia, without additional power driving, greatly reducing energy consumption, and continuously rotating the sorting method to improve production efficiency.

[0027] The present application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.
[0028] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and embodiments.
[0029] The above describes the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
[0030] Figure 1 Fig. 1 shows a structural schematic diagram of an automatic sorting device of open-structured parts according to an embodiment of the present application; Figure 1As shown, the main structure of the automatic sorting device is a sorting rotary body, and further comprises a sorting force releasing mechanism. In one specific example, the sorting rotary body is a roller 1, and the open structure part 2 is a U-shaped structure which is clamped and matched by the clamping force between the open part and the edge of the roller 1. The edge thickness of the roller 1 is set as the standard opening width of the open structure part (the standard opening width can be a range of required sizes). The roller 1 can rotate around the central axis, and the sorting force releasing mechanism releases the sorting force of the open structure part 1 which is opposite to the clamping force, so as to separate the open structure part 2 with clamping force smaller than the sorting force from the sorting rotary body, that is, to separate the unqualified parts. In one specific application example, the roller 1 is vertically placed, and the sorting force releasing mechanism is the open structure part 2 itself. At this time, the sorting force of the open structure part 2 is its own gravity, and when the open structure part 2 rotates with the roller 1, the opening direction of the open structure part 2 will change, for example Figure 1 When the open structure part 2 rotates from above the roller 1 to below, the opening direction of the open structure part 2 changes from downward opening to upward opening. At this time, for the open structure part 2 of the lower half of the roller 1, if the clamping force between the open structure part 2 and the roller 1 is smaller than the gravity, the open structure part 2 will fall off from the roller 1, so as to achieve the sorting effect. Although Figure 1 The rotation direction of the roller 1 shown in the figure is counterclockwise, but it should be recognized that the reverse clockwise rotation can also achieve the corresponding sorting effect.
[0031] In some other embodiments, the sorting force can also include the centrifugal force generated by the rotation of the roller 1, or the acting force applied by other devices, for example: the roller 1 is horizontally placed, and the sorting force releasing mechanism can be a blowing structure arranged in the roller 1. The blowing structure points to the bottom of the open structure part 2 at the edge of the roller 1, and blows out the defective products with clamping force not meeting the requirements by the air flow force, which can also achieve the technical effect of sorting out the parts with too large opening size, and can control the sorting force by the control precision of the air flow force, thereby improving the sorting precision.
[0032] According to another aspect of the present application, Figures 2a-2c The structure diagram of the automatic sorting system of the open structure part according to one embodiment of the present application is shown in the figure, and the automatic sorting system is shown in the front view of the automatic sorting system. Figure 2a The front view of the automatic sorting system is shown in the figure, and the automatic sorting system is shown in the front view of the automatic sorting system. Figure 1The automatic sorting device shown in the base further comprises a feeding mechanism and a receiving mechanism. The feeding mechanism comprises a feeding track 3 and a vibrating device 4. The open structure parts 2 are arranged upside down on the feeding track 3. The vibrating device 4 is arranged below the feeding track 3. The vibrating device 4 drives the open structure parts to be evenly distributed and transported forward. The receiving mechanism comprises an unqualified product receiving area 7 and a qualified product receiving area 8. The unqualified product receiving area 8 corresponds to the open structure parts 2 separated from the roller 1 due to the clamping force being less than the sorting force. In this embodiment, the roller 1 is vertically arranged. The qualified product receiving area 7 is arranged below the area after the bottom of the roller 1 in the rotating direction. The unqualified product receiving area 8 is arranged below the area before the bottom of the roller 1 in the rotating direction. In this way, the classification of the sorted parts is accurate, and the subsequent process is facilitated.
[0033] In specific embodiments, in combination with Figure 2b the perspective view of the automatic sorting system, and Figure 2c the top view of the automatic sorting system, the automatic sorting device comprises a roller 1 and a first driving mechanism 11. The first driving mechanism 11 is connected with the roller 1 to ensure stable rotation of the roller. The edge thickness of the roller 1 matches the qualified opening size of the open structure parts 2. A transmission mechanism 5 is further arranged between the feeding mechanism and the automatic sorting device. The transmission mechanism 5 is a belt transmission mechanism. The transmission mechanism 5 is used to transfer the open structure parts 2 on the feeding track 3 to the roller 1 and clamp the open structure parts 2 on the edge of the roller 1. The transmission mechanism 5 specifically comprises a third driving mechanism 51, a driving wheel 52, a driven wheel 53, a belt 54 and a pressing wheel 55. The third driving mechanism 51 is connected with the driving wheel 52. The belt 53 is arranged on the driving wheel 52 and the driven wheel 53. The belt 54 is in contact with the top surface of the inverted open structure parts 2. The belt 54 is used to transfer the open structure parts 2 from the feeding track 3 to the roller 1. The pressing wheel 55 is arranged between the driving wheel 52 and the driven wheel 53. The pressing wheel 55 presses the belt 54 towards the roller 1 to ensure effective clamping of the parts with the roller 1.
[0034] In specific embodiments, a poking device 6 is arranged above the qualified product receiving area 8. The poking device 6 comprises a poking rod 61 and a second driving mechanism 62. The second driving mechanism 62 is connected with the poking rod 61 to drive the poking rod 61 to rotate. The poking rod 61 is in contact with the qualified open structure parts 2 (i.e. the open structure parts 2 with the clamping force greater than the sorting force) on the roller 1 when the poking rod 61 rotates. The qualified parts move with the roller 1 to the area of the poking rod 61 due to the clamping force being greater than the sorting force. The poking rod 61 peels off the qualified parts by synchronous rotation to avoid stagnation. Preferably, the poking rod 61 is arranged in pairs and corresponds to the open structure parts 2 on both sides of the roller 1. The rotation direction of the poking rod 61 is consistent with the rotation direction of the roller 1 to ensure that the qualified parts can be effectively peeled off from the roller 1.
[0035] In specific embodiments, the automatic sorting system described above can be arranged on a frame base, and the frame base is provided with adjustable supporting legs and walking wheels, which can be transferred to the mold production line as needed to realize online sorting, and the height of the supporting legs is adjusted to make the automatic sorting system stable. In this scenario, the discharge part 9 of the mold is connected with the feeding track 3, and the parts discharged from the mold are transferred through the feeding track 3 to the sorting device area, realizing online sorting. The qualified product receiving area 8 is connected with the conveying mechanism 10 to convey the sorted qualified parts to the next process (such as the downstream packaging or assembly process), forming a complete automatic production process.
[0036] In specific embodiments, a wireless sensor is arranged on the feeding mechanism, which will abnormally alarm and stop when the opening of the opening structure part 2 is too small. At the same time, a sensor can also be set on the sorting device, which can alarm the punch to remind the staff to adjust the opening size when consecutive unqualified products are sorted out, avoiding a large number of defective products from flowing out. The online sorting system can ensure that the opening size is qualified, and at the same time, it can avoid the appearance of defective products due to mold problems.
[0037] The utility model provides a kind of automatic sorting device and automatic sorting system of opening structure part, and high-efficiency sorting is realized by the synergistic effect of the rotary motion of sorting rotary body (such as roller) and clamping force-sorting force.It has high sorting precision: physical size matching and mechanics balance are combined to avoid misjudgment;Efficiency is improved: machine is connected with mold synchronously, and it is suitable for high-speed production;Cost is reduced: manual sorting is cancelled, and defective product flow is reduced;And compact and reliable structure: modular design is suitable for space limited scene etc. Advantageous effect, effectively solve the pain points of traditional sorting, such as relying on manual, low efficiency and high miss rate.
