[0001] The present invention belongs to the field of gear processing, and particularly relates to an automatic sorting device for half-shaft gears. Background Art

[0002] The half-shaft gear has a shaft body and is in a "T" shape. During the automated processing, after its initial processing and before transportation, when multiple gears need to be transferred to a conveyor belt for transportation, it is usually done manually or by mechanical equipment.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. If not specifically specified, the technical means used in the embodiments are conventional means well known to those skilled in the art. Figures 1 - 6 In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0032] For example, an automatic sorting device for a differential side gear includes a first conveyor belt 1, a second conveyor belt, a detection table 4, a guide rail 5, and a grasping mechanism.

[0033] Such as Figure 1 A plurality of gears 8 are conveyed on the first conveyor belt 1. A turning member 101 is provided at the discharging end of the first conveyor belt 1. The turning member 101 is used to turn the gear 8 upside down. The second conveyor belt is provided at the output end of the turning member 101. The detection table 4 is provided between the first conveyor belt 1 and the second conveyor belt. The grasping mechanism is installed on the guide rail 5. The grasping mechanism is used to grasp the gears 8 on the first conveyor belt 1 and the second conveyor belt onto the detection table 4.

[0034] The grasping mechanism is used to grasp the gear 8 with the shaft body 802 facing upward on the first conveyor belt 1. After the gear 8 with the shaft body 802 facing downward passes through the turning member 101 and is turned over, it is grasped by the grasping mechanism on the second conveyor belt.

[0035] The grasping mechanism is used to grasp the gear 8 with the shaft body 802 facing upward on the first conveyor belt 1. After the gear 8 with the shaft body 802 facing downward passes through the turning member 101 and is turned over, it is grasped by the grasping mechanism on the second conveyor belt.

[0036] The conveying directions of the first conveyor belt 1 and the second conveyor belt are the same. The gear 8 is a prior art, i.e., a bevel gear. The gear 8 has a "T" - shaped structure, which includes a tooth part 801 and a shaft body 802. The inner end face of the tooth part 801 is fixedly connected to the shaft body 802. Teeth are provided on the outer end face of the tooth part 801, and the outer diameter of the tooth part 801 is greater than the outer diameter of the shaft body 802. It should be noted that when the gear 8 is stably placed, there are only two states: one is the state where the shaft body 802 faces upward, and the other is the state where the shaft body 802 faces downward. Due to the weight and geometric structure of the shaft body 802 itself, the gear 8 cannot be placed obliquely. In the present invention, after rough machining of the gear 8, it is adjusted to a unified state, and the placement states of each gear are adjusted and sorted to facilitate subsequent automated processing of the fixed posture of the gear 8. In the present invention, the state where the shaft body 802 faces upward is the target posture.

[0037] During specific implementation, workers or a conveying device place a plurality of gears 8 on the first conveyor belt 1. The gears 8 on the first conveyor belt 1 are in a disordered state with inconsistent postures. The grasping mechanism first grasps the gear 8 with the shaft body 802 facing upward on the first conveyor belt 1, and then places it on the detection table 4 for detection. The gears 8 that do not conform to the target posture, that is, the gears with the shaft body 802 facing downward, enter the flipping component 101 for flipping, and then are output from below the first conveyor belt 1. The output gears 8 have the shaft body 802 facing upward and conform to the target posture. Thus, these flipped gears 8 are continuously conveyed by the second conveyor belt and are grasped by the grasping mechanism and placed on the detection table 4 for detection. Compared with the prior art, the present invention can adjust the posture of the feeding process of the bevel gears after initial processing, adjust several bevel gears to a unified posture, and then perform subsequent detection, conveying, and processing, facilitating the design of automated operations and improving production efficiency.

[0038] The detection table 4 is a prior art, and it is provided with a detection device 401. The detection device 401 can be a weighing detection device, a dimension detection device, an infrared detection device, a phase adjustment device, etc. in the prior art, and can be freely customized according to different technological processes. The guide rail 5 is a prior art, and the guide rail slider 601 can move linearly. The top of the guide rail 5 can be fixed to the top bracket or ceiling of the factory building through a connecting rod. The guide rail 5, the first conveyor belt 1, and the second conveyor belt are parallel, and the length directions of the three are in the same plane.

[0039] As Figure 3 、 Figure 4 As shown in, the grasping mechanism includes a linear lifting device 602, a sleeve 607, and an electromagnet 608; the guide rail slider 601 of the guide rail 5 is fixedly connected to the top of the linear lifting device 602, the bottom of the linear lifting device 602 is connected to the sleeve 607, the sleeve 607 is provided with an installation cavity with an opening facing downward, and the electromagnet 608 is installed in the installation cavity;

[0040] The inner diameter of the installation cavity is adapted to the shaft body 802 and is used for inserting into the shaft body 802; the linear lifting device 602 is used for lifting the sleeve 607 so that the installation cavity is sleeved on the shaft body 802;

[0041] When the grasping mechanism performs grasping, for the two postures of the gear 8, there are the following two implementation manners:

[0042] When the shaft body 802 of the gear 8 faces upward, the sleeve 607 moves to the target grasping position, the installation cavity is sleeved on the shaft body 802, the end face of the sleeve 607 abuts against the inner end face of the tooth part 801, and there is a clearance distribution between the top end of the shaft body 802 and the electromagnet 608, and the electromagnet 608 can adsorb the gear 8; for example Figure 3 At this time, there is a small clearance between the electromagnet 608 and the end face of the shaft body 802. Under the action of the electromagnet 608, the gear 8 can be firmly adsorbed. When the electromagnet 608 is powered off, the action of putting down the gear 8 is performed.

[0043] When the shaft body 802 faces downward, the end face of the sleeve 607 abuts against the outer end face of the tooth part 801, the tooth part 801 and the electromagnet 608 are spaced apart, and the electromagnet 608 cannot adsorb the gear 8. For example Figure 4 At this time, the shaft body 802 is below the sleeve 607, and there is a large gap between the electromagnet 608 and the tooth part 801. Under the influence of this gap, the magnetic force of the electromagnet 608 cannot hold the gear 8.

[0044] Therefore, in the present invention, the grasping mechanism can only suck the gear 8 with the shaft body 802 facing upward, while the gear 8 with the shaft body 802 facing downward continues to be conveyed by the first conveyor belt 1, and after being flipped by the flipping member 101, finally the gears 8 on the first conveyor belt 1 and the second conveyor belt are all in the posture with the shaft body 802 facing upward. In addition, a detection component, such as a photoelectric sensor, a proximity switch, etc., can be arranged in the sleeve 607 to detect whether the shaft body 802 is in place. If the shaft body 802 is not adsorbed, it means that it is not the target posture, so the first conveyor belt 1 conveys the next gear 8 for grasping.

[0045] Furthermore, the sleeve 607 is made of non-magnetic materials such as plastics and non-ferromagnetic metals. The top of the sleeve 607 is fixedly connected to a slide rod 604. The slide rod 604 is slidably connected to a fixing plate 603. The fixing plate 603 is fixedly connected to the bottom of the linear lifting device 602. A spring 606 is sleeved on the slide rod 604. The two ends of the spring 606 respectively abut against the fixing plate 603 and the sleeve 607. As Figure 4 When the shaft body 802 of the gear 8 faces downward, the slide rod 604 moves upward and the spring 606 is compressed, which can prevent the gear 8 from being crushed.

[0046] A plurality of sliding rods 604 can be provided, and their tops slidably pass through the fixing plate 603 and are fixedly connected to the limiting blocks 605. If the linear lifting device 602 is designed with multiple strokes, it will cause the PLC automatic control part to be relatively complex. Therefore, in the present invention, the linear lifting device 602 is designed with two strokes. One is the maximum stroke, at this time the sleeve 607 is at the lowest height, and the operations of grasping and placing are carried out in this stroke; the other is the minimum stroke, at this time the sleeve 607 is at the highest height, and the operations of transferring and moving the guide rail slider 601 are carried out in this stroke.

[0047] Furthermore, the top of the electromagnet 608 is spaced from the top inner wall of the installation cavity. The top of the electromagnet 608 is fixedly connected to an adjusting bolt 609. The adjusting bolt 609 is threadedly connected to the top of the sleeve 607 for adjusting the height of the electromagnet 608. By adjusting the height of the electromagnet 608, the relative magnetic force can be adjusted.

[0048] Furthermore, one or two grasping mechanisms are provided;

[0049] When there is one, the grasping mechanism successively grasps the gears 8 on the first conveyor belt 1 and the second conveyor belt; and places them on the inspection table 4 for inspection. After the inspection of the gears 8, they are placed on the second conveyor belt by this grasping mechanism for conveying to the next process.

[0050] When there are two, the two grasping mechanisms are respectively used to grasp the gears 8 on the first conveyor belt 1 and the second conveyor belt.

[0051] Furthermore, when there are two grasping mechanisms, they are respectively the first grasping mechanism 61 and the second grasping mechanism 62; the first grasping mechanism 61 is used to grasp the gear 8 on the first conveyor belt 1, and the second grasping mechanism 62 is used to grasp the gear 8 on the second conveyor belt;

[0052] A baffle 10 is provided on the second conveyor belt. The front side of the baffle 10 is used to block the flipped gear 8, and the part of the second conveyor belt behind the baffle 10 is used to convey the gear 8; the gear 8 blocked by the baffle 10 is the gear 8 grasped by the second grasping mechanism 62; the second grasping mechanism 62 is used to grasp the gear 8 on the inspection table 4 to the back side of the baffle 10 and on the second conveyor belt.

[0053] It should be noted that the second conveyor belt conveys multiple gears 8. The multiple gears 8 are conveyed in a single row in a straight line on the second conveyor belt, which can be achieved by designing the width of the second conveyor belt and installing a flow guide plate 7 on the second conveyor belt. Therefore, when the gear 8 abuts against the front side of the baffle 10, a sliding friction is generated between the gear 8 and the second conveyor belt, and the gear 8 is positioned to facilitate the second grasping mechanism 62 to grasp it. If the grasping mechanism is designed as one, the grasping mechanism also grasps the gear 8 that abuts against the baffle 10.

[0054] Further, the second conveyor belt includes a first horizontal section 201, an inclined climbing section 202, and a second horizontal section 203 arranged in sequence; the height of the first horizontal section 201 is lower than that of the second horizontal section 203, and the bottom of the detection table 4 is fixedly connected to a bracket, and the bracket straddles the inclined climbing section 202; the first horizontal section 201 is located at the output end of the flipping member 101, and the baffle 10 is arranged on the second horizontal section 203.

[0055] The first horizontal section 201, the inclined climbing section 202, and the second horizontal section 203 can be an integral conveyor belt device or three separate conveyor belt devices. The height of the second horizontal section 203 is increased through the inclined climbing section 202, so that the height difference is relatively small when the grasping mechanism places the gear 8.

[0056] The second horizontal section 203 and the first conveyor belt 1 can be designed to be at the same height. In this case, the grasping mechanism only needs to be designed with two states, namely the maximum stroke and the minimum stroke. The second horizontal section 203 and the first conveyor belt 1 can also be designed to be at different heights. Then, the grasping mechanism needs to be designed with three strokes to correspond to the height of the first conveyor belt 1 (the first stroke), the height of the second horizontal section 203 (the second stroke), and the highest height when moving along with the guide rail slider 601 (the third stroke).

[0057] Further, the flipping member 101 includes a semi-circular housing. The end of the first conveyor belt 1 is arranged inside the semi-circular housing, and a limiting channel is formed between the end and the inner wall surface of the semi-circular housing; after the gear 8 passes through the limiting channel, it is located below the first conveyor belt 1 and completes an up-and-down flip; the bottom opening of the limiting channel is located directly above the first horizontal section 201.

[0058] The semi-circular housing can be fixed by a fixing frame, which wraps the end of the feeding end of the first conveyor belt 1. The width of the limiting channel is adapted to the gear 8 to prevent the axis of the gear 8 from shifting. The top of the limiting channel is the feeding inlet, and the bottom is the discharging opening. The gear 8 enters from the feeding inlet, is output from the discharging opening, and completes a 180° up-and-down flip to form an attitude with the shaft body 802 facing up. The gear 8 is distributed with a gap from the limiting channel, and the gear 8 moves downward under its own weight and the action of the first conveyor belt 1.

[0059] The bottom of the semi-circular housing forms a space for the gear 8 to pass through with the first horizontal section 201, and multiple gears 8 sequentially fall from the semi-circular housing onto the first horizontal section 201.

[0060] As Figure 5 , two guiding plates 7 are fixedly arranged on the first conveyor belt 1, and a passage for only one gear 8 to pass through is formed between the two guiding plates 7. The end of the guiding plate 7 abuts against the limiting plate 9. The limiting plate 9 is connected to the pushing device 902. The limiting plate 9 blocks the passage, and the pushing device 902 is used to push the limiting plate 9 to open the passage. The pushing device 902 is fixedly connected to the fixing plates on both sides of the first conveyor belt 1. The output end of the pushing device 902 is fixedly connected to the extension rod 901, and the extension rod 901 is fixedly connected to the limiting plate 9.

[0061] As Figure 6 , a feed bin 3 is arranged at the input end of the first conveyor belt 1. The feed bin 3 includes a hopper 301, a guiding bin 303, a switch plate 304 and a driving device 305; the hopper 301 is used to put multiple gears 8 into it.

[0062] The bottom of the hopper 301 is arranged in the guiding bin 303. The guiding bin 303 is provided with a blanking port 306 for only one gear 8 to pass through. The outside of the blanking port 306 is attached to the switch plate 304. The switch plate 304 is connected to the driving device 305 and is used to open the blanking port 306. The hopper 301 is fixedly connected to the column 302 to achieve the supporting function. The blanking port 306 is located directly above the input end of the first conveyor belt 1. The driving device 305 is fixed on the guiding bin 303. The inner bottom surface of the guiding bin 303 is arc-shaped to achieve the function of guiding to the blanking port 306.

[0063] The driving device 305, the linear lifting device 602 and the pushing device 902 are all prior arts, such as air cylinders, electric cylinders, hydraulic cylinders, etc.

[0064] Specifically, the implementation process is as follows:

[0065] When the switch board 304 opens the blanking port 306, multiple gears 8 pass through the blanking port 306 in sequence and are output onto the first conveyor belt 1. Then they are guided by the diversion plate 7 and accumulate. The limiting plate 9 blocks the channel and abuts against the gear 8, and the gear 8 slides against the first conveyor belt 1 within the channel. Then the switch board 304 closes the blanking port 306. The first conveyor belt 1 stops, and the grasping mechanism grasps the gear 8 that abuts against the limiting plate 9. If it fails to be grasped, it grasps the next adjacent gear 8, and the grasped gear 8 is directly placed on the inspection table 4. During this process, the guide rail slider 601 moves at the same interval as the grasping mechanism in sequence, and the interval length is the axial distance between two adjacent gears 8. When grasping, the total length of the movement of the guide rail slider 601 is less than the length of the channel. That is to say, after the gears 8 in the channel are grasped, the limiting plate 9 opens the channel, and the first conveyor belt 1 moves a length of one channel. The gears 8 that do not meet the posture requirements are input into the flipping component 101 for flipping. Then the limiting plate 9 closes the channel, the blanking port 306 opens for replenishing materials, and then the above-mentioned grasping process is repeated again.

[0066] When the grasping mechanism is designed as one, after the grasping mechanism places the gear 8 on the inspection table 4, it waits for the inspection to be completed, then grasps the inspected gear 8, moves it to the rear side of the baffle 10, places the gear 8 on the rear side of the baffle 10, and the second horizontal section 203 conveys the inspected gear 8. Then the grasping mechanism grasps the gear 8 that abuts against the baffle 10 onto the inspection table 4 and conveys it to the rear side of the baffle 10 after the inspection is completed. Therefore, when the grasping mechanism is designed as one, the grasping mechanism alternately grasps the gears 8 on the first and second conveyor belts.

[0067] When the grasping mechanism is designed as two, such as Figure 2 , the two grasping mechanisms respectively grasp the gears 8 on the first and second conveyor belts, and after the inspection is completed, the second grasping mechanism 62 places the gear 8 on the rear side of the baffle 10.

[0068] In the present invention, both the baffle 10 and the limiting plate 9 realize the functions of positioning and accumulating the gears 8. And the second conveyor belt not only realizes the function of transporting the gears 8 with the target posture, but also can continue to convey the gears 8 to the next process after the inspection is completed. When grasping on the second conveyor belt, it is preferably in a stopped state.

[0069] In addition, the present invention can also use other means to transfer the gears 8 on the inspection table 4, such as manually removing them, using a conveyor belt, etc. If this method is adopted, the baffle 10 can be cancelled and the length of the second horizontal section 203 can be shortened.

[0070] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, variations, modifications, and substitutions made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
