[0045] The material sorting device of a vehicle production line is one of the key equipment in a vehicle production line. It can classify and transport various vehicle parts through assembly line operation. Since there are many kinds of parts transported by a vehicle production line, in order to save costs, there are usually multiple parts sharing one conveyor line, which makes it difficult to classify the parts when they need to be assembled or taken. Therefore, in order to solve the above problems, the present invention provides a material sorting device for a vehicle production line, such as Figure 1 and Figure 2 As shown, the vehicle production line material sorting device may include a first conveying component 10 , a transfer component 20 , a lifting component 30 , a first collecting component 40 , a second collecting component 50 and a third collecting component 60 .

[0046] In this embodiment, if Figure 1 As shown, the first conveying assembly 10 may include a first conveying frame 11 and a plurality of first rollers 12. The first conveying assembly 10 may be located at a first height. The first conveying frame 11 may be detachably connected to the plurality of first rollers 12. When the first conveying assembly 10 carries material, the plurality of first rollers 12 may rotate toward the transfer assembly 20 to convey the material to the transfer assembly 20.

[0047] like Figure 1 , Figure 2 As shown, the transfer assembly 20 may include a transfer frame 21 and a plurality of transfer rollers 22. The height of the transfer assembly 20 may be adjusted, and the transfer frame 21 may be detachably connected to the transfer rollers 22. The transfer assembly 20 may be adjusted to an appropriate height to convey the material according to the volume and weight of the material.

[0048] like Figure 5As shown, the lifting assembly 30 may include a first spring-lifting portion 31 and a second spring-lifting portion 32, and the heights of the first spring-lifting portion 31 and the second spring-lifting portion 32 may be adjusted. The transfer assembly 20 may also include a first portion 23, a second portion 24, and a sliding groove 25. The first portion 23 of the transfer assembly 20 may be rotatably connected to the first spring-lifting portion 31. The second portion 24 of the transfer assembly 20 may be rotatably connected to the second spring-lifting portion 32. The sliding groove 25 may be slidably connected to the first portion 23, so that the spacing between the first portion 23 and the second portion 24 may be adjusted. The first portion 23 and the second portion 24 may both be located at the bottom of the transfer assembly 20. The first spring-lifting portion 31 may be located on a side of the second spring-lifting portion 32 close to the first conveying assembly 10. The first spring-lifting portion 31 and the second spring-lifting portion 32 respectively apply an upward elastic force to the transfer assembly 20. Thus, when the material is located on the transfer assembly 20, the lifting assembly 30 has sufficient elastic force to support the transfer assembly 20. Furthermore, according to the weight and volume of the material on the transfer assembly 20 , the first elastic portion 31 and the second elastic portion 32 can cause a certain change in the height and the tilt angle of the transfer assembly 20 .

[0049] The first collecting assembly 40 is located at a first height. The first collecting assembly 40 can collect materials with a relatively light weight, such as packaging outer boxes, protective films, etc., conveyed by the first conveying assembly 10. The second collecting assembly 50 is located at a second height. The second collecting assembly 50 can collect materials with a relatively heavy weight and a relatively large volume, such as a subframe, a torsion beam, etc., conveyed by the first conveying assembly 10. The third collecting assembly 60 is located at a third height. Both the second height and the third height are lower than the first height, and the materials can be better classified. The first collecting assembly 40, the second collecting assembly 50, and the third collecting assembly 60 are distributed around the transfer assembly 20. The third collecting assembly 60 is located vertically below the first conveying assembly 10. The third collecting assembly 60 can collect materials with a relatively heavy weight and a relatively small volume, such as swing arms, steering knuckles, and brakes, etc., conveyed by the first conveying assembly 10. The lifting assembly 30 and the transfer assembly 20 can reasonably classify the materials by changing the height and inclination angle of the transfer assembly 20 according to the volume and weight of different materials. This can greatly improve the efficiency of material sorting, and does not require multiple transmission lines for sorting, thereby reducing the cost of the material sorting device of the vehicle production line.

[0050] Among them, the transfer component 20 may include a first state, a second state and a third state.

[0051] like Figure 2As shown, the first state may include: the transfer assembly 20 is in a horizontal state. The transfer assembly 20 is at a first height. The first conveying assembly 10, the transfer assembly 20 and the first collection assembly 40 are connected in sequence. When the weight of the material conveyed by the first conveying assembly 10 to the transfer assembly 20 is relatively light, the transfer assembly 20 may be in the first state, and the inertial force conveyed by the first conveying assembly 10 may directly convey the material to the first collection assembly 40.

[0052] like Figure 3 As shown, the second state may include: the transfer component 20 is in a horizontal state. The transfer component 20 is at a second height. The transfer component 20 is connected to the second collection component 50. When the material transported to the transfer component 20 by the first conveying component 10 is heavy and large in volume, due to the elastic force of the lifting component 30, the heavy and large material can press the transfer component 20 down to the second height and connect with the second collection component 50, that is, the transfer component 20 is in the second state. Thus, the heavy and large material is transported to the second collection component 50. Then, due to the upward elastic force of the lifting component 30, the transfer component 20 can be restored to the first height to prepare for subsequent material classification, thereby improving the efficiency of material sorting.

[0053] like Figure 4 As shown, the third state may include: the transfer assembly 20 is in an inclined state, one side of the transfer assembly 20 is tilted downward to a third height and connected with the third collection assembly 60. When the material conveyed by the first conveying assembly 10 is heavy and small in volume, the side of the transfer assembly 20 close to the first conveying assembly 10 may be tilted downward to the third height and connected with the third collection assembly 60, so that the heavy and small material can slide into the third collection assembly 60. Then, due to the upward elastic force of the lifting assembly 30, the transfer assembly 20 can be restored to the first height to prepare for subsequent material sorting, thereby improving the efficiency of material sorting.

[0054] The first state of the transfer component 20 can be connected to the first collection component 40, the second state of the transfer component 20 can be connected to the second collection component 50, and the third state of the transfer component 20 can be connected to the third collection component 60. Therefore, the materials can be transported to the corresponding first collection component 40, the second collection component 50, and the third collection component 60 through the adjustment of the transfer component 20 to complete the classification of the materials. That is, the height and inclination angle of the transfer component 20 can be changed according to the weight and volume of the materials to complete the classification of the materials, and there is no need to use multiple transmission lines to classify the materials, and only one transmission line is needed to complete the classification of the materials. Thereby reducing the cost of the material sorting device of the vehicle production line and greatly improving the efficiency of material sorting.

[0055] In some embodiments, the first collection component 40, the second collection component 50 and the third collection component 60 can be components such as conveyor lines and collection boxes. That is, the first collection component 40, the second collection component 50 and the third collection component 60 can be collection storage boxes or transmission tracks. The transmission tracks can transport the sorted materials to the corresponding workstations. The vehicle production line material sorting device can include a second conveying component 90, which is located on the side of the transfer component 20 close to the first collection component 40. Figure 1 As shown, the second conveying assembly 90 may include a second conveying frame 91 and a second roller 92. The second conveying assembly 90 may be connected with the transfer assembly 20 and the first collecting assembly 40. The second conveying assembly 90 may prevent the materials in the first collecting assembly 40 from affecting the materials to be transported later because the first collecting assembly 40 is parallel to the transfer assembly 20 after the materials are transported to the first collecting assembly 40, and the second roller 92 may rotate toward the first collecting assembly 40 to increase the conductive force of the materials toward the first collecting assembly 40, thereby enabling the vehicle production line material sorting device to accurately classify the materials.

[0056] In this embodiment, if Figure 2 As shown, the conveying direction of the material by the first conveying assembly 10 is perpendicular to the conveying direction of the material by the transfer assembly 20. Thus, when the transfer assembly 20 is in the second state, since the conveyed material is large in volume and heavy in weight, the transfer roller 22 of the transfer assembly 20 can rotate toward the second collection assembly 50, so that the material can have sufficient conduction force to be conveyed to the second collection assembly 50, and the large and heavy material can be prevented from stagnating in the transfer assembly 20. In this way, it is not necessary to set a rotating mechanism to allow the transfer assembly 20 to rotate and then convey the material to the second collection assembly 50, thereby simplifying the structure of the vehicle production line material sorting device and making the operation more stable.

[0057] In this embodiment, if Figure 4 As shown, the second spring-lifting part 32 is located at the middle of the transfer component 20, away from the side of the first conveying component 10. There can be two second spring-lifting parts 32. When the transfer component 20 is in the third state, the conveyed material is small in volume and heavy in weight, and the length of the material is less than the distance between the first end and the second spring-lifting part 32, so that the end of the transfer component 20 close to the first conveying component 10 can be more easily tilted toward the third collection component 60, so that the small and heavy material can slide into the third collection component 60. In this way, the vehicle production line material sorting device can classify the material more accurately.

[0058] In this embodiment, if Figure 1As shown, the first end of the transfer assembly 20 can point to the first conveying assembly 10 in the first state. The second end of the transfer assembly 20 can point to the first collecting assembly 40 in the first state. The distance between the first end and the second end is the length of the transfer assembly 20.

[0059] The distance from the first spring-lifting portion 31 to the first end portion is 20% to 40% of the length of the transfer assembly 20. The distance from the second spring-lifting portion 32 to the second end portion is 30% to 45% of the length of the transfer assembly 20. By controlling the first spring-lifting portion 31 and the second spring-lifting portion 32 within the above range, materials with larger volume and heavier weight can be pressed down smoothly on the transfer assembly 20, and materials with smaller volume and heavier weight can more easily press the transfer assembly 20 down to the third state. This allows the vehicle production line material sorting device to accurately classify materials.

[0060] In this embodiment, if Figure 3 As shown, the vehicle production line material sorting device may further include an auxiliary component 70. The auxiliary component 70 may include two guides 72. There is a spacing between the two guides 72. When the transfer component 20 is at the second height, it is located between the two guides 72. In this way, when the material with a large volume and a heavy weight presses the transfer component 20 down to the second height, the material can be transported to the second collection component 50 along the space between the two guides 72 to prevent the material from sliding out from the side of the transfer component 20. In this way, the material with a large volume and a heavy weight can be accurately transported to the second collection component 50.

[0061] In this embodiment, if Figure 3 As shown, the second height is lower than the third height, and when a large and heavy material is located on the transfer assembly 20, the material can be prevented from being conveyed to the third conveying assembly, and the second collection assembly 50 and the third collection assembly 60 can be prevented from interfering with each other. Thus, the material can be accurately classified.

[0062] In this embodiment, if Figure 3 As shown, the auxiliary component 70 may further include a limit portion 71. The limit portion 71 may be located vertically below the transfer component 20, and the transfer component 20 may abut against the top of the limit portion 71 when it descends to the second height. In this way, when a material with a large volume and a heavy weight is located on the transfer component 20, the transfer component 20 is pressed down to the second height, and the limit portion 71 may support the transfer component 20. This can prevent the height of the transfer component 20 from being lower than the second height due to the excessive weight of the material, and being unable to connect with the second collection component 50. This allows the vehicle production line material sorting device to accurately classify the materials.

[0063] In this embodiment, if Figure 1As shown, the vehicle production line material sorting device may further include an identification component 80, and the identification component 80 may include a weighing platform 81 and a depth camera 82. The weighing platform 81 may be used to detect the weight of the material, and the depth camera 82 may be used to detect the size of the material, and then the manipulator may grab the detected material to the first conveying component 10. The identification component 80 may make a judgment on the material to be classified, so that the first conveying component 10 and the transfer component 20 are adjusted to the corresponding parameters, and thus the vehicle production line material sorting device may accurately classify the material.

[0064] In this embodiment, if Figure 6 As shown, a vehicle production line material sorting method includes:

[0065] Step S10, based on the image information taken by the depth camera 82 and the weighing result of the weighing platform 81, the sensor detects that there is material on the first conveyor line, and the type of material on the first conveyor line and the status of the transfer component 20 can be obtained.

[0066] Step S20, based on the fact that the type of material on the first conveyor line is first-class material, such as packaging boxes, protective films, etc., and the transfer component 20 is in the first state. The first conveyor line can be controlled to convey the first-class material toward the transfer component 20, and the conveying speed is greater than the first preset speed, and the weight of the first-class material is less than the preset weight. The preset weight is less than or equal to the sum of the elastic forces of the first elastic part 31 and the second elastic part 32 in the first state. In this way, the transfer component 20 can be located at a first height, arranged horizontally, and can be connected with the first collection component 40. Since the first-class material is lighter in weight and the first preset speed is faster, when the first-class material is conveyed at the first preset speed, the first-class material can directly reach the first collection component 40 by inertia. Thereby, the classification of the first-class material can be completed.

[0067] In this embodiment, the vehicle production line material sorting method further includes steps S30 to S40, and steps S30 to S50 may be described in detail below.

[0068] Step S30, based on the fact that the type of material on the first conveyor line is the second type of material, such as a subframe, a torsion beam, etc., and the transfer assembly 20 is in the first state, the first conveyor line can be controlled to convey the second type of material toward the transfer assembly 20, and the conveying speed is less than the second preset speed. Therefore, after the second type of material is conveyed to the transfer assembly 20, the second type of material has a smaller inertia and a larger friction force, so that it can stagnate on the transfer assembly 20, preventing the second material from being conveyed to the first collection assembly 40.

[0069] The weight of the second type of material is greater than the preset weight. The length of the second type of material is the size of the second type of material along the conveying direction of the first conveying component 10. In the first state, the end of the transfer component 20 close to the first conveying component 10 is the first end. The length of the second type of material is greater than the distance between the first end and the second elastic lifting part 32. The second preset speed is less than the first preset speed. In this way, the second type of material can stagnate on the transfer component 20, and the stability of the transfer component 20 can be guaranteed.

[0070] Step S40, based on the arrival of the second type of materials at the transfer component 20, the status of the transfer component 20 is obtained.

[0071] Step S50, since the second type of materials are large in size and heavy in weight, the transfer assembly 20 can be pressed down to be in the second state, that is, the transfer assembly 20 is at the second height, in a horizontal state, and connected with the second collection assembly 50. Then the transfer assembly 20 can be controlled to convey the second type of materials toward the second collection assembly 50. Thus, the classification of the second type of materials is completed. Then, due to the upward elastic force of the lifting assembly 30, the transfer assembly 20 can be restored to the first height to prepare for the subsequent material classification.

[0072] In this embodiment, the vehicle production line material sorting method may further include step S60, and step S60 may be described in detail below.

[0073] Step S60, based on the type of the material on the first conveying line being the third type of material, such as a swing arm, a steering knuckle, and a brake, and the transfer assembly 20 being in the first state, the first conveying line can be controlled to convey the third type of material toward the transfer assembly 20, and the conveying speed is less than the third preset speed, so that the third type of material can be located at a distance between the first end of the transfer assembly 20 and the second spring-lifting portion 32.

[0074] Among them, the weight of the third type of material is greater than the elastic force of the first elastic part 31 in the first state. The length of the third type of material is the size of the third type of material along the conveying direction of the first conveying component 10. The length of the third type of material is less than the distance between the first end and the second elastic part 32. Since the length of the third type of material is less than the distance between the first end and the second elastic part 32, the transfer component 20 is in the third state, that is, the transfer component 20 is tilted toward one end of the first conveying component 10 and connected with the third collection component 60. Therefore, the third type of material can rely on the tilt of the transfer component 20 to slide into the third collection component 60, thereby completing the classification of the third type of material. Then, due to the upward elastic force of the lifting component 30, the transfer component 20 can be restored to the first height to prepare for subsequent material classification.
