[0070] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any changes in mechanism, method, or function made by a person skilled in the art according to the embodiments are all within the protection scope of the present invention.

[0071] The terms used herein, such as "upper", "lower", "left", "right", "front", "back", etc., which indicate relative spatial positions, are used for the purpose of convenience to describe the relationship between one feature and another feature as shown in the accompanying drawings. It is understood that, depending on the placement of the product, the terms of relative spatial positions may be intended to include different orientations other than those shown in the drawings, and should not be construed as limitations on the claims. In addition, the descriptor "horizontal" used herein is not completely equivalent to being perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0072] like Figure 1-2 As shown, an embodiment of the present invention provides a product production system 100, which includes a transport unit 30 and a product processing device 20. The transport unit 30 is used to transport the product, for example, to transport the product to the product processing device 20 so that the product processing device 20 can process the product.

[0073] The product in this embodiment is a component for a car chassis, and the product processing equipment 20 is a welding device for welding the components of the car chassis. In other embodiments, the product may be other types of components, and the product processing equipment 20 may be a device for implementing other processes, which is not limited here.

[0074] The above-mentioned multiple products include a first product 41 and a second product 42. The handling unit 30 has multiple material taking structures, including a first material taking structure 321, a second material taking structure 322, and a third material taking structure 323. The product processing equipment 20 has multiple workstations for processing products, including a first workstation 21. It can be imagined that the product production system 100 also includes a driving unit 50 for driving the handling unit 30 to move. The driving unit 50 can be a driving device such as a manipulator.

[0075] The product production system 100 also includes a product storage rack 10, which is used to store a variety of products. The product storage rack 10 is also provided with a visual positioning unit 101 for locating the position of the product. The visual positioning unit 101 can obtain the position of the product on the product storage rack 10, and the transport unit 30 can accurately obtain the corresponding product according to the position of the product obtained by the visual positioning unit 101.

[0076] In this embodiment, the number of the product storage racks 10 is not limited to one. For example, two product storage racks 10 may be provided, and the two product storage racks 10 are arranged opposite to each other.

[0077] like Figure 3-18 As shown, the present invention further provides a product production method, which can be applied to the above-mentioned product production system 100, and the product production method includes the following steps:

[0078] S1, such as Figure 4 , 6 As shown, the first product 41 is obtained by the first material taking structure 321 of the transport unit 30 , and the second product 42 is obtained by the second material taking structure 322 of the transport unit 30 .

[0079] S2, such as Figure 7 As shown, the first semi-finished product 46 on the first workstation 21 is obtained by the third material taking structure 323 of the transport unit 30. The first semi-finished product 46 is obtained by the first product 41 and the second product 42 after at least a first processing process.

[0080] S3, such as Figure 8 As shown, the first product 41 obtained by the first material picking structure 321 and the second product 42 obtained by the second material picking structure 322 are placed in the first workstation 21, and then the first product 41 and the second product 42 on the first workstation 21 are processed using at least a first processing process to form a first semi-finished product 46 on the first workstation 21.

[0081] It should be noted that although the present application provides a flowchart and operating steps for the product production method, based on routine or no creative labor, for steps that do not have a necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the implementation mode of the present application.

[0082] The product production method provided in this embodiment is capable of being carried out in a cycle. In step S2, the "first semi-finished product 46 on the first station 21" in "obtaining the first semi-finished product 46 on the first station 21 through the third material picking structure 323 of the conveying unit 30" can be understood as the first semi-finished product 46 placed on the first station 21 by the conveying unit 30 during the last production cycle.

[0083] According to the above steps S1-S3, the transport unit 30 first obtains the first product 41 and the second product 42 from the product storage rack 10, and then moves to the product production equipment, takes out the first semi-finished product 46 on the first station 21, and then puts the first product 41 and the second product 42 into the first station 21. Since the first semi-finished product 46 is obtained by the first product 41 and the second product 42 after at least the first processing process, when the first product 41 and the second product 42 are put into the first station 21, the product production equipment will use the first processing process to process the first product 41 and the second product 42 on the first station 21, so that the first semi-finished product 46 is formed on the first station 21 again.

[0084] It can be seen that the product production method provided in this embodiment can flexibly grab a variety of products according to demand, improve the efficiency of product production, and reduce the labor cost of product production.

[0085] The above-mentioned multiple products also include a third product 43 and a fourth product 44. The multiple material taking structures also include a fourth material taking structure 324. The multiple workstations also include a second workstation 22. The product production method also includes the following steps:

[0086] S4, such as Fig. 9 As shown, the third product 43 is obtained by the first material taking structure 321 , and the fourth product 44 is obtained by the second material taking structure 322 .

[0087] In other embodiments, in step S4 , the third product 43 may be obtained through the second material taking structure 322 , and the fourth product 44 may be obtained through the first material taking structure 321 .

[0088] S5, such as Fig.10 As shown, the second semi-finished product 47 on the second workstation 22 is obtained by the fourth material taking structure 324 of the transport unit 30, and 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.

[0089] S6, such as Fig.11 As shown, the third product 43 obtained by the first material picking structure 321 and the fourth product 44 obtained by the second material picking structure 322 are placed in the second workstation 22, and then the third product 43 and the fourth product 44 on the second workstation 22 are processed using at least a second processing process to form a second semi-finished product 47 on the second workstation 22.

[0090] As described above, the product production method provided in this embodiment can be carried out in a cycle. In step S5, the "second semi-finished product 47 on the second station 22" in "obtaining the second semi-finished product 47 on the second station 22 through the fourth material picking structure 324 of the conveying unit 30" can be understood as the second semi-finished product 47 placed on the second station 22 by the conveying unit 30 during the last production cycle.

[0091] Similar to the above steps S1-S3, the above steps S4-S6 are adopted, the transport unit 30 first obtains the third product 43 and the fourth product 44 from the product storage rack 10, and then the transport unit 30 moves to the product production equipment, takes out the second semi-finished product 47 on the second station 22, and then puts the third product 43 and the fourth product 44 into the second station 22. Since the second semi-finished product 47 is obtained by the third product 43 and the fourth product 44 after at least the second processing process, when the third product 43 and the fourth product 44 are placed in the second station 22, the product production equipment will use the second processing process to process the third product 43 and the fourth product 44, so that the second semi-finished product 47 will be formed on the second station 22.

[0092] After the above steps S1-S6, the handling unit 30 obtains the first semi-finished product 46 and the second semi-finished product 47, and places the first product 41 and the second product 42 into the first station 21, and places the third product 43 and the fourth product 44 into the second station 22. In this way, a new first semi-finished product 46 will be formed on the first station 21, and a new second semi-finished product 47 will be formed on the second station 22, thereby realizing the continuous production of multiple products.

[0093] In this embodiment, the first semi-finished product 46 and the second semi-finished product 47 are two mirror-symmetrical parts. Of course, the first semi-finished product 46 and the second semi-finished product 47 can also be two identical parts, which is not specifically limited here.

[0094] In this embodiment, both the first processing process and the second processing process are welding processes, that is, the first semi-finished product 46 is formed by welding the first product 41 and the second product 42, and the second semi-finished product 47 is formed by welding the third product 43 and the fourth product 44. The specific content of the first processing process is determined according to the welding requirements of the first product 41 and the second product 42, and the specific content of the second processing process is determined according to the welding requirements of the third product 43 and the fourth product 44.

[0095] The plurality of workstations mentioned above further include a third workstation 23, and the product production method further includes the following steps:

[0096] S7, such as Fig.12As shown, the first total finished product 48 on the third workstation 23 is obtained by a certain material picking structure on the transport unit 30 except the third material picking structure 323 and the fourth material picking structure 324. The first total finished product 48 is obtained by the second semi-total finished product 47 after at least the third processing process.

[0097] In the above step S7, since the third material picking structure 323 has been used to obtain the first semi-finished product 46, and the fourth material picking structure 324 has been used to obtain the second semi-finished product 47, in order to obtain the first finished product 48 on the third workstation 23, only one material picking structure other than the third material picking structure 323 and the fourth material picking structure 324 can be used.

[0098] Specifically, in step S7 , the “certain material picking structure” in “obtaining the first total finished product 48 on the third workstation 23 through a certain material picking structure other than the third material picking structure 323 and the fourth material picking structure 324 on the transport unit 30 ” is the first material picking structure 321 .

[0099] S8, such as Fig.13 As shown, the second semi-finished product 47 obtained by the fourth material taking structure 324 is placed in the third work station 23, and then the second semi-finished product 47 on the third work station 23 is processed using at least a third processing process to form a first finished product 48 on the third work station 23.

[0100] In step S7, the "first total finished product 48 on the third workstation 23" in "obtaining the first total finished product 48 on the third workstation 23 through a material picking structure other than the third material picking structure 323 and the fourth material picking structure 324 on the conveying unit 30" can be understood as the first total finished product 48 on the third workstation 23 placed by the conveying unit 30 during the last production cycle.

[0101] According to the above steps S7-S8, the transport unit 30 first obtains the first finished product 48 from the third station 23, and then the transport unit 30 puts the second semi-finished product 47 obtained previously into the third station 23. Since the first finished product 48 is obtained by subjecting the second semi-finished product 47 to at least the third processing process, when the second semi-finished product 47 is placed in the third station 23, the product production equipment will process the second semi-finished product 47 using the third processing process, so that the first finished product 48 is formed on the third station 23 again.

[0102] The plurality of products further include a fifth product 45. To transform the second semi-finished product 47 into the first finished product 48, the fifth product 45 needs to be loaded into the second semi-finished product 47. For this purpose, the plurality of material taking structures further include a fifth material taking structure 325. The product production method further includes the following steps:

[0103] Sa, such as Figure 5 As shown, the fifth product 45 is obtained by the fifth picking structure 325 of the transport unit 30 .

[0104] After "putting the second semi-finished product 47 obtained by the fourth material taking structure 324 into the third workstation 23" in step S8, the following steps are also included:

[0105] S9, such as Fig.14 As shown, the fifth product 45 obtained by the fifth material taking structure 325 is loaded into the second semi-finished product 47 on the third workstation 23.

[0106] It should be noted that the above step Sa can be performed before the step of "obtaining the first semi-finished product 46 on the first workstation 21 through the third material taking structure 323 of the transport unit 30" in step S2.

[0107] The plurality of workstations mentioned above further includes a fourth workstation 324, and the product production method further includes the following steps:

[0108] S10, such as Fig.15 As shown, the second total finished product 49 on the fourth workstation 324 is obtained by a certain material taking structure on the transport unit 30 except for the material taking structure that obtains the first total finished product 48 and the third material taking structure 323. The second total finished product 49 is obtained by the first half total finished product 46 after at least the fourth processing process.

[0109] For step S10, it should be noted that the "certain material picking structure" in "obtaining the second total finished product 49 on the first workstation 21 through a certain material picking structure on the conveying unit 30 other than the material picking structure that obtains the first total finished product 48 and the third material picking structure 323" is the fourth material picking structure 324.

[0110] S11, such as Fig.16 As shown, the first half of the finished product 46 obtained by the third material taking structure 323 is placed in the fourth station 324, and then the first half of the finished product 46 on the fourth station 324 is processed using at least a fourth processing process to form a second finished product 49 on the fourth station 324.

[0111] In step S10, the "second total finished product 49 on the fourth station 324 is obtained by a material picking structure on the conveying unit 30 other than the material picking structure that obtains the first total finished product 48 and the third material picking structure 323" can be understood as the second total finished product 49 on the fourth station 324 placed by the conveying unit 30 during the last production cycle.

[0112] According to the above steps S10-S11, the transport unit 30 first obtains the second finished product 49 from the fourth station 324, and then the transport unit 30 puts the first semi-finished product 46 obtained previously into the fourth station 324. Since the second finished product 49 is obtained by the second semi-finished product 47 after at least the fourth processing process, when the first semi-finished product 46 is put into the fourth station 324, the product production equipment will use the fourth processing process to process the first semi-finished product 46, so that the second finished product 49 will be formed on the fourth station 324.

[0113] The product production system 100 also includes a material unloading conveyor line 60. After the above step S11, the transport unit 30 obtains the first total finished product 48 and the second total finished product 49. Thereafter, the transport unit 30 can place the first total finished product 48 and the second total finished product 49 into the material unloading conveyor line 60. The material unloading conveyor line 60 can transport the first total finished product 48 and the second total finished product 49 to a designated position for unloading.

[0114] The unloading conveyor line 60 may also be provided with a coding machine 61 for coding the first master finished product 48 and the second master finished product 49. After the first master finished product 48 and the second master finished product 49 are coded, it is easy to identify each first master finished product 48 and each second master finished product 49.

[0115] In this embodiment, the third processing and the fourth processing are welding processes, that is, the first overall finished product 48 is made by welding the second semi-overall finished product 47, and the second overall finished product 49 is made by welding the first semi-overall finished product 46. The specific content of the third processing is determined according to the welding requirements of the second semi-overall finished product 47, and the specific content of the fourth processing is determined according to the welding requirements of the first semi-overall finished product 46.

[0116] In order to transform the first semi-finished product 46 into the second semi-finished product 49, the fifth product 45 needs to be loaded into the first semi-finished product 46. By comparison, the product production method further includes the following steps after "putting the first semi-finished product 46 obtained by the third material taking structure 323 into the fourth workstation 324" in step S11:

[0117] Sb, such as Fig.17 As shown, the fifth product 45 is obtained by the fifth material taking structure 325 of the transport unit 30.

[0118] S12, such as Fig.18 The fifth product 45 obtained by the fifth material taking structure 325 is loaded into the first semi-finished product 46 on the fourth station 324 .

[0119] like Figure 2As shown, the transport unit 30 includes a main structure 31, a first swing arm 33 rotatably connected to the main structure 31, a second swing arm 34 rotatably connected to the first swing arm 33, a first driving structure 35 for driving the first swing arm 33 to rotate relative to the main structure 31, and a second driving structure 36 for driving the second swing arm 34 to rotate relative to the first swing arm 33.

[0120] Driven by the first driving structure 35, the first swing arm 33 can rotate relative to the main structure 31, and driven by the second driving structure 36, the second swing arm 34 can rotate relative to the first swing arm 33. In this embodiment, the first material picking 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 material picking structure 322 and the fifth material picking structure 325 are respectively located on the two sides of the rotation axis of the second swing arm 34.

[0121] like Figure 4-6 As shown, the step of “obtaining the first product 41 through the first material-retrieving structure 321 of the transport unit 30, and obtaining the second product 42 through the second material-retrieving structure 322 of the transport unit 30” and step Sa, obtaining the fifth product 45 through the fifth material-retrieving structure 325 of the transport unit 30 are specifically as follows:

[0122] Obtain the first product 41 through the first material taking structure 321 of the transport unit 30;

[0123] After the first swing arm 33 rotates by a preset angle, the fifth product 45 is obtained by the fifth material taking structure 325;

[0124] After the second swing arm 34 rotates by a preset angle, the second product 42 is obtained by the second material taking structure 322 .

[0125] When the transport unit 30 obtains the first product 41, the second product 42 and the fifth product 45, the first material-retrieving structure 321 can be used to obtain the first product 41, and then the first swing arm 33 rotates a preset angle (such as 180°) to interchange the positions of the second material-retrieving structure 322 and the fifth material-retrieving structure 325 with the first material-retrieving structure 321, and then the fifth material-retrieving structure 325 obtains the fifth product 45, and then the second swing arm 34 rotates a preset angle (such as 180°) to interchange the positions of the second material-retrieving structure 322 and the fifth material-retrieving structure 325, and then the second material-retrieving structure 322 obtains the second product 42. With the above arrangement, the transport unit 30 can flexibly obtain a variety of products according to demand.

[0126] In the above steps, the transport unit 30 sequentially obtains the first product 41, the fifth product 45, and the second product 42. It is conceivable that the order in which the transport unit 30 sequentially obtains the products can be changed in permutations and combinations. For example, the order in which the products are obtained can also be the first product 41, the second product 42, the fifth product 45, or the fifth product 45, the second product 42, the first product 41, or the second product 42, the fifth product 45, the first product 41.

[0127] The above step S4, obtaining the third product through the first material taking structure 321, and obtaining the fourth product 44 through the second material taking structure 322 is specifically as follows:

[0128] Obtain the third product 43 through the first material taking structure 321 of the transport unit 30;

[0129] After the first swing arm 33 rotates by a preset angle, the fourth product 44 is obtained by the second material taking structure 322 .

[0130] With the above arrangement, when the transport unit 30 acquires the third product 43 and the fourth product 44, the first material picking structure 321 can first acquire the third product 43, and then the first swing arm 33 rotates a preset angle (for example, 180°) to interchange the positions of the second material picking structure 322 and the first material picking structure 321, and then the second material picking structure 322 acquires the fourth product 44.

[0131] It is conceivable that when the transport unit 30 obtains the third product 43 and the fourth product 44 , the second material-grabbing structure 322 may first obtain the fourth product 44 , and then the swing arm rotates to enable the first material-grabbing structure 321 to obtain the third product 43 .

[0132] In this embodiment, the product production system 100 also includes a memory and a processor. The memory stores a computer program that can be run on the processor. When the processor executes the computer program, the steps of any one of the above-mentioned product production methods are implemented.

[0133] like Figure 2 , 19 As shown in Figure 23, in this 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 rotates within a large range, so that the positions of the second material-retrieving structure 322 together with the fifth material-retrieving structure 325 and the first material-retrieving structure 321 can be interchanged, and the second swing arm 34 rotates within a first small range, so that the positions of the fifth material-retrieving structure 325 and the second material-retrieving structure 322 can be interchanged.

[0134] The first material picking structure 321 includes a first material picking member 3211 for picking up products, and a third driving structure 3212 connecting the first swing arm 33 and the first material picking member 3211. The third driving structure 3212 is used to drive the first material picking member 3211 to rotate relative to the first swing arm 33. The rotation axis of the first material picking member 3211 is perpendicular to the rotation axis of the first swing arm 33.

[0135] With the above arrangement, after the first material picking member 3211 picks up the product, the third driving structure 3212 can drive the first material picking member 3211 to rotate, so that the product picked up by the first material picking member 3211 can also rotate with it. In this way, interference between the product picked up by the first material picking member 3211 and the transport unit 30 can be avoided during the subsequent rotation of the first swing arm 33.

[0136] The fifth material picking structure 325 is used to obtain the product in the shape of a tube sleeve (i.e., the fifth product 45), which includes a plurality of claws 3251, a claw driving member 3252 connecting the plurality of claws 3251 and the second swing arm 34, the plurality of claws 3251 are arranged along the circumferential direction of the claw driving member 3252, and the claw driving member 3252 is used to drive the plurality of claws 3251 to move along its radial direction.

[0137] When the second material-retrieving structure 322 retrieves the product, the plurality of claws 3251 first extend into the product, and then the claw driving member 3252 drives the plurality of claws 3251 to move in the radial direction of the claw driving member 3252 away from the axis of the claw driving member 3252, so that the plurality of claws 3251 press against the product from the inside of the product, thereby driving the product to move. When the second material-retrieving structure 322 needs to release the product, the claw driving member 3252 drives the plurality of claws 3251 to move in the radial direction of the claw driving member 3252 close to the axis of the claw driving member 3252.

[0138] In this embodiment, the first driving structure 35 includes a first driving member 351, a first transmission wheel 352 and a second transmission wheel 353 rotatably connected to the main structure 31, and a transmission member 354 transmission-connected to the first transmission wheel 352 and the second transmission wheel. One of the first transmission wheel 352 and the second transmission wheel 353 is arranged to rotate synchronously with the first swing arm 33, and the other is driven to rotate by the first driving member 351.

[0139] Assume that the first driving member 351 drives the first transmission wheel 352 to rotate. When the first transmission wheel 352 rotates, the second transmission wheel 353 can also be driven to rotate through the transmission member 354. When the second transmission wheel 353 rotates, the first swing arm 33 will also rotate accordingly. In this way, by controlling the first driving member 351, the first swing arm 33 can be controlled to rotate.

[0140] The first driving member 351 may specifically include a servo motor 3511 and a reducer 3512 connected to the output end of the servo motor 3511, wherein the output end of the reducer 3512 is connected to the first transmission wheel 352. The servo motor 3511 can accurately control the rotation angle of the first swing arm 33, and the reducer 3512 can increase the output torque of the servo motor 3511.

[0141] Furthermore, the transport unit 30 also includes a tensioning mechanism 37 connected to the main structure 31 , and the tensioning mechanism 37 is used to tension 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 .

[0142] The transmission member 354 includes 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 includes a tensioning wheel 371 in contact with the side of the first connecting section 3543 facing away from the second connecting section 3544, and an adjustment structure for driving the tensioning wheel 371 to approach and move away from the second connecting section 3544. Under the action of the adjustment structure 372, the tensioning wheel 371 can adjust the tightness of the transmission member 354.

[0143] In this embodiment, the tension wheel 371 is located on the outside of the transmission member 354, that is, the tension wheel 371 contacts the side of the first connecting section 3543 facing away from the second connecting section 3544. In other embodiments, the tension wheel 371 can also be located on the inside of the transmission member 354, that is, the tension wheel 371 contacts the side of the first connecting section 3543 facing the second connecting section 3544.

[0144] In this embodiment, the fourth material-grabbing structure 324 and the fifth material-grabbing structure 325 are fixedly arranged relative to the main structure 31, and the fourth material-grabbing structure 324 and the fifth material-grabbing structure 325 are arranged relatively in the width direction of the main structure 31, and the first swing arm 33 is rotatably connected to one side in the length direction of the main structure 31. The fourth material-grabbing structure 324, the fifth material-grabbing structure 325 and the first swing arm 33 are respectively located on different sides of the main structure 31, so that the fourth material-grabbing structure 324, the fifth material-grabbing structure 325 and the first material-grabbing structure 321, the second material-grabbing structure 322, and the third material-grabbing structure 323 on the first swing arm 33 can grab products on different sides of the main structure 31, making the working mode of the transport unit 30 more flexible.

[0145] The length direction of the main structure 31 and the width direction of the main structure 31 are two perpendicular directions. Specifically, the length direction of the main structure 31 is the width direction of the main structure 31. Fig. 22The vertical direction of the main structure 31 is the vertical direction of the main structure 31 in the state shown. Fig. 22 Left and right direction in the displayed state.

[0146] The main structure 31 includes a main body 311 , a first connecting arm 312 connected to one side of the main body 311 in the length direction, and a second connecting arm 313 and a third connecting arm 314 respectively connected to both sides of the main body 311 in the length direction.

[0147] The first swing arm 33 is rotatably connected to the side of the first connecting arm 312 away from the main body 311 , the third material picking structure 323 is connected to the side of the second connecting arm 313 away from the main body 311 , and the fourth material picking structure 324 is connected to the side of the third connecting arm 314 away from the main body 311 .

[0148] The first connecting arm 312, the second connecting arm 313 and the third connecting arm 314 are slender, so that the first picking structure 321, the second picking structure 322, the fifth picking structure 325 on the first swing arm 33, the third picking structure 323 on the second connecting arm 313, and the fourth picking structure 324 on the third connecting arm 314 can all extend into a narrow space to grab products.

The first material picking member 3211, the second material picking member 3221, the third material picking member 3231, and the fourth material picking member 3241 are all magnetic members, and all obtain products by magnetic attraction.

[0150] The products are obtained by magnetic attraction. When obtaining the products, only the iron parts on the products that can be attracted by the magnets are needed. It is not limited by the specific shape of the products. Therefore, a variety of products can be grabbed compatibly.

[0151] To sum up, in the product production method and product production system 100 provided by the present invention, the transport unit 30 has multiple material picking structures, which can flexibly obtain or method multiple products according to needs to achieve continuous transportation of multiple products, improve the efficiency of product production, and reduce the labor cost of product production.
