[0045] As Figure 1As shown in FIG. 2, the utility model provides a product production system 100, the product production system 100 includes a carrying unit 30. The carrying unit 30 is used for carrying products, for example, carrying products to a product processing device 20 to process the products by the product processing device 20.

[0046] The product in the embodiment is a part for an automobile chassis, and the product processing device 20 is a welding device used for welding the part for the automobile chassis. In other embodiments, the product can also be other kinds of parts, and the product processing device 20 can also be a device used for implementing other processes, which is not limited herein.

[0047] The carrying unit 30 includes a main body structure 31 and a plurality of material taking structures connected to the main body structure 31. The material taking structures are used for taking products, and the carrying unit 30 is provided with a plurality of material taking structures, that is, the carrying unit 30 can take a plurality of products at the same time to improve the efficiency of product production.

[0048] To drive the carrying unit 30 to move, the product production system 100 further includes a driving unit 50 used for driving the carrying unit 30 to move, which can be a mechanical hand or other driving device.

[0049] The product production system 100 further includes a product storage rack 10 used for storing a plurality of products.

[0050] In the embodiment, the number of the product storage racks 10 is not limited to one, for example, the product storage rack 10 can be provided with two product storage racks 10 arranged oppositely.

[0051] Continuously combining Figure 3 As shown in FIG. 7, the plurality of material taking structures include a first material taking structure 321, a second material taking structure 322 and a fifth material taking structure 325. The carrying unit 30 further includes a first swing arm 33 rotatably connected to the main body structure 31, a second swing arm 34 rotatably connected to the first swing arm 33, a first driving structure 35 used for driving the first swing arm 33 to rotate relative to the main body structure 31, and a second driving structure 36 used for driving the second swing arm 34 to rotate relative to the first swing arm 33.

[0052] The first swing arm 33 is capable of rotating relative to the main body structure 31 under the drive of the first drive structure 35, and the second swing arm 34 is capable of rotating relative to the first swing arm 33 under the drive of the second drive structure 36. In the embodiment, the first taking structure 321 and the second swing arm 34 are respectively connected to the two sides of the rotation axis of the first swing arm 33, and the second taking structure 322 and the fifth taking structure 325 are respectively located on the two sides of the rotation axis of the second swing arm 34.

[0053] When the product production system 100 is running, a plurality of products are needed, and the plurality of products include the first product 41, the second product 42, and the fifth product 45. With the above arrangement, when the carrying unit 30 obtains the products, the first taking structure 321 can be used to obtain the first product 41 first, then the first swing arm 33 is rotated by a preset angle (such as 180°), so that the positions of the second taking structure 322 and the fifth taking structure 325 are interchanged with the position of the first taking structure 321, then the fifth taking structure 325 is used to obtain the fifth product 45, then the second swing arm 34 is rotated by a preset angle (such as 180°), so that the positions of the fifth taking structure 325 and the second taking structure 322 are interchanged, and then the second taking structure 322 is used to obtain the second product 42.

[0054] It can be seen that the carrying unit 30 provided in the embodiment can flexibly grasp a plurality of products through the rotation of the first swing arm 33 and the second swing arm 34, thereby improving the product production efficiency.

[0055] In the embodiment, the length of the first swing arm 33 is greater than the length of the second swing arm 34. The first swing arm 33 is rotated in a large range, so that the positions of the second taking structure 322 and the fifth taking structure 325 can be interchanged with the position of the first taking structure 321, and the second swing arm 34 is rotated in a small range, so that the positions of the fifth taking structure 325 and the second taking structure 322 are interchanged.

[0056] The first taking structure 321 includes a first taking piece 3211 for obtaining a product, and a third drive structure 3212 connecting the first swing arm 33 and the first taking piece 3211, and the third drive structure 3212 is also used to drive the first taking piece 3211 to rotate relative to the first swing arm 33. The rotation axis of the first taking piece 3211 is perpendicular to the rotation axis of the first swing arm 33.

[0057] With the above arrangement, after the first taking piece 3211 obtains the product, the third drive structure 3212 can drive the first taking piece 3211 to rotate, so that the product obtained by the first taking piece 3211 can also rotate, thereby avoiding the interference between the product obtained by the first taking piece 3211 and the carrying unit 30 in the subsequent rotation process of the first swing arm 33.

[0058] The fifth taking structure 325 is used for taking the product in the form of a sleeve, which comprises a plurality of clamping claws 3251, a clamping claw driving member 3252 connecting the plurality of clamping claws 3251 and the second swing arm 34, the plurality of clamping claws 3251 being arranged along the circumferential direction of the clamping claw driving member 3252, and the clamping claw driving member 3252 being used for driving the plurality of clamping claws 3251 to move along the radial direction thereof.

[0059] When the fifth taking structure 325 takes the product, the plurality of clamping claws 3251 first extend into the product, and then the clamping claw driving member 3252 drives the plurality of clamping claws 3251 to move along the radial direction of the clamping claw driving member 3252 away from the axis of the clamping claw driving member 3252, so that the plurality of clamping claws 3251 abut against the product from the inside of the product, thereby being able to drive the product to move. When the second taking structure 322 needs to release the product, the clamping claw driving member 3252 drives the plurality of clamping claws 3251 to move along the radial direction of the clamping claw driving member 3252 close to the axis of the clamping claw driving member 3252.

[0060] In the embodiment, the first driving structure 35 comprises a first driving member 351, a first transmission wheel 352 and a second transmission wheel 353 rotationally connected to the main body structure 31, and a transmission member 354 transmissionally connecting the first transmission wheel 352 and the second transmission wheel 353, one of the first transmission wheel 352 and the second transmission wheel 353 being synchronously rotationally arranged with the first swing arm 33, and the other being rotationally driven by the first driving member 351.

[0061] Supposing that the first driving member 351 drives the first transmission wheel 352 to rotate, the first transmission wheel 352 rotates, and the second transmission wheel 353 is also driven to rotate by the transmission member 354, the second transmission wheel 353 rotates, and the first swing arm 33 also rotates, so that the rotation of the first swing arm 33 can be controlled by controlling the first driving member 351.

[0062] The first driving member 351 can specifically comprise a servo motor 3511 and a speed reducer 3512 connected to the output end of the servo motor 3511, and the output end of the speed reducer 3512 is connected to the first transmission wheel 352. The servo motor 3511 can be used to accurately control the rotation angle of the first swing arm 33, and the speed reducer 3512 can be used to increase the output torque of the servo motor 3511.

[0063] Further, the carrying unit 30 further comprises a tensioning mechanism 37 connected to the main body structure 31, which is used for tensioning the transmission member 354, so as to ensure the friction between the transmission member 354 and the first transmission wheel 352 and the second transmission wheel 353.

[0064] The transmission member 354 comprises a first contact section 3541 in contact with the first transmission wheel 352, a second contact section 3542 in contact with the second transmission wheel 353, a first connecting section 3543 and a second connecting section 3544 connecting the first contact section 3541 and the second contact section 3542, and the first connecting section 3543 and the second connecting section 3544 are non-crossed. The tensioning mechanism 37 comprises a tensioning wheel 371 in contact with a side of the first connecting section 3543 away from the second connecting section 3544, and an adjusting structure for driving the tensioning wheel 371 to approach and move away from the second connecting section 3544. Under the action of the adjusting structure 372, the tensioning wheel 371 can adjust the tightness of the transmission member 354.

[0065] In the embodiment, the tensioning wheel 371 is located on the outside of the transmission member 354, i.e., the tensioning wheel 371 contacts the side of the first connecting section 3543 away from the second connecting section 3544. In other embodiments, the tensioning wheel 371 can also be located on the inside of the transmission member 354, i.e., the tensioning wheel 371 contacts the side of the first connecting section 3543 toward the second connecting section 3544.

[0066] In the embodiment, the carrying unit 30 further comprises a third picking structure 323 and a fourth picking structure 324, the third picking structure 323 and the fourth picking structure 324 are fixedly arranged relative to the main body structure 31, the third picking structure 323 and the fourth picking structure 324 enable the carrying unit 30 to carry more products, the manner in which the carrying unit 30 carries multiple products can also become more flexible, and the working efficiency of the carrying unit 30 is generally improved.

[0067] In the embodiment, the third picking structure 323 and the fourth picking structure 324 are arranged opposite to each other in the width direction of the main body structure 31, and the first swing arm 33 is rotationally connected to one side of the main body structure 31 in the length direction, i.e., the third picking structure 323, the fourth picking structure 324, and the first swing arm 33 are respectively located on different sides of the main body structure 31, so that the third picking structure 323, the fourth picking structure 324, and the first picking structure 321, the second picking structure 322, and the fifth picking structure 325 on the first swing arm 33 can obtain products on different sides of the main body structure 31, and the working manner of the carrying unit 30 is more flexible.

[0068] The length direction of the main body structure 31 and the width direction of the main body structure 31 are two perpendicular directions. Specifically, the length direction of the main body structure 31 is the up-down direction when the main body structure 31 is in the state shown in FIG. 1, and the width direction of the main body structure 31 is the left-right direction when the main body structure 31 is in the state shown in FIG. 1. Figure 6 Figure 6

[0069] ​​The main body structure 31 comprises a main body part 311, a first connecting arm 312 connected to one side of the main body part 311 in the length direction, a second connecting arm 313 and a third connecting arm 314 connected to the two sides of the main body part 311 in the length direction respectively.

[0071] The first connecting arm 312, the second connecting arm 313 and the third connecting arm 314 are in an elongated shape, so that the first taking structure 321, the second taking structure 322 and the fifth taking structure 325 on the first swing arm 33, and the third taking structure 323 on the second connecting arm 313 and the fourth taking structure 324 on the third connecting arm 314 can all extend into a narrow space to grab products.

The first taking part 3211, the second taking part 3221, the third taking part 3231 and the fourth taking part 3241 are all magnetic parts, and all acquire products by magnetic attraction.

[0073] Acquiring products by magnetic attraction, when acquiring products, only the product has an iron part that can be attracted by magnetism, and is not limited by the specific shape of the product, so that a variety of products can be compatibly grabbed.

[0074] The above-mentioned variety of products includes a first product 41, a second product 42, a third product 43, a fourth product 44 and a fifth product 45, and the product processing equipment 20 has a plurality of stations for processing products, and the plurality of stations include a first station 21, a second station 22, a third station 23 and a fourth station 24. The working process of the product production system 100 provided in this embodiment is as follows:

[0075] S1, as shown in Figure 8 , 10 The first product 41 is acquired by the first taking structure 321 of the carrying unit 30, and the second product 42 is acquired by the second taking structure 322 of the carrying unit 30.

[0076] S2, as shown in Figure 11As shown, the first half assembly product 46 on the first station 21 is obtained by the third picking structure 323 of the carrying unit 30, and the first half assembly product 46 is made of the first product 41 and the second product 42 after at least the first processing process.

[0077] S3、as Figure 12 As shown, the first product 41 obtained by the first picking structure 321 and the second product 42 obtained by the second picking structure 322 are placed in the first station 21, and then the first product 41 and the second product 42 on the first station 21 are processed by at least the first processing process to form the first half assembly product 46 on the first station 21.

[0078] The working process of the product production system 100 provided by the embodiment can be cyclically performed. In step S2, the first half assembly product 46 on the first station 21 in the step of “obtaining the first half assembly product 46 on the first station 21 by the third picking structure 323 of the carrying unit 30” can be understood as the first half assembly product 46 placed on the first station 21 by the carrying unit 30 in the last production cycle.

[0079] Before the step of “obtaining the first half assembly product 46 on the first station 21 by the third picking structure 323 of the carrying unit 30” in step S2, the process Sa of “obtaining the fifth product 45 by the fifth picking structure 325 of the carrying unit 30” is further included.

[0080] As shown, the first product 41 obtained by the first picking structure 321 and the second product 42 obtained by the second picking structure 322 are placed in the first station 21, and then the first product 41 and the second product 42 on the first station 21 are processed by at least the first processing process to form the first half assembly product 46 on the first station 21. Figure 8 As shown in -10, the steps of “obtaining the first product 41 by the first picking structure 321 of the carrying unit 30, and obtaining the second product 42 by the second picking structure 322 of the carrying unit 30” and the process Sa of “obtaining the fifth product 45 by the fifth picking structure 325 of the carrying unit 30” are specifically:

[0081] The first product 41 is obtained by the first picking structure 321 of the carrying unit 30;

[0082] After the first swing arm 33 rotates by a preset angle, the fifth product 45 is obtained by the fifth picking structure 325;

[0083] After the second swing arm 34 rotates by a preset angle, the second product 42 is obtained by the second picking structure 322.

[0084] When the handling unit 30 acquires the first product 41, the second product 42, and the fifth product 45, the first picking structure 321 can first acquire the first product 41. Then, the first swing arm 33 rotates by a preset angle (e.g., 180°), causing the positions of the second picking structure 322 and the fifth picking structure 325 to interchange with those of the first picking structure 321. Next, the fifth picking structure 325 acquires the fifth product 45. Then, the second swing arm 34 rotates by a preset angle (e.g., 180°), causing the positions of the second picking structure 322 and the fifth picking structure 325 to interchange. Finally, the second picking structure 322 acquires the second product 42. Using this configuration, the handling unit 30 can flexibly acquire multiple products according to requirements.

[0085] The workflow of the product manufacturing system 100 provided in this embodiment also includes:

[0086] S4, such as Figure 13 As shown, the third product 43 is obtained through the first material handling structure 321, and the fourth product 44 is obtained through the second material handling structure 322. Step S4 specifically involves:

[0087] The third product 43 is obtained through the first material handling structure 321 of the handling unit 30;

[0088] After the first swing arm 33 rotates to a preset angle, the fourth product 44 is obtained through the second material handling structure 322.

[0089] With the above configuration, when the conveying unit 30 acquires the third product 43 and the fourth product 44, the first picking structure 321 can acquire the third product 43 first, and then the first swing arm 33 can rotate a preset angle (e.g., 180°) to exchange the positions of the second picking structure 322 and the first picking structure 321. Then, the second picking structure 322 can acquire the fourth product 44.

[0090] S5, such as Figure 14 As shown, the second semi-finished product 47 on the second station 22 is obtained by the fourth material handling structure 324 of the handling unit 30. The second semi-finished product 47 is obtained by the third product 43 and the fourth product 42 after at least the second processing process.

[0091] As described above, the workflow of the product manufacturing system 100 provided in this embodiment is cyclical. In step S5, "the second semi-finished product 47 on the second station 22 is obtained by the fourth material picking structure 324 of the conveying unit 30" can be understood as the product placed on the second station 22 by the conveying unit 30 during the last production cycle.

[0092] S6, such as Figure 15As shown, the third product 43 obtained by the first picking structure 321 and the fourth product 44 obtained by the second picking structure 322 are placed in the second station 22, and then the third product 43 and the fourth product 44 on the second station 22 are processed by using at least a second processing process, so as to form a second half assembly product 47 on the second station 22.
