Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a production line of vehicle parts. BACKGROUND

[0002] Generally, in the production process of a vehicle door, a plurality of parts required for assembling the vehicle door are loaded into a full material box through a vehicle door build-up line. Then, the full material box is transferred to a vehicle door assembly line by manual or logistics vehicle. During the conveying of the full material box along the vehicle door assembly line, an assembly worker takes the parts in the material box in turn and assembles them to the vehicle door, thereby completing the production of the vehicle door. After that, the empty material box is transferred to the vehicle door build-up line by manual or logistics vehicle to perform the build-up process of the plurality of parts required for the vehicle door again. Here, the "build-up" refers to a logistics mode in which the parts are arranged according to the assembly sequence of the vehicle and sent to the assembly line in sequence within a specified time during the production process.

[0003] However, due to the long transfer distance of the full material box, the heavy weight, and the need for manual loading and unloading of the material box, the personnel operation intensity is high, the transfer time is long, and the overall production efficiency is low, which cannot meet the demand of fast production rhythm.

[0058] Generally, a semi-automatic door type conveying device uses an upper and lower layer to carry empty material boxes and full material boxes. Empty material boxes and full material boxes need to be put in and taken out alternately by manual operation, which cannot meet the demand of fast production rhythm, requires high man-machine combination, and has low production efficiency. Especially for the scene of putting in and taking out multiple material boxes in multiple assembly lines and sequential construction lines, the conveying form of the semi-automatic door type conveying device is single, and cannot meet the automation demand when multiple material boxes are put in synchronously.

[0059] To this end, some embodiments of the present application provide a production line. The production line is suitable for a production scene in which left and right doors (such as left and right front doors or left and right rear doors) of a vehicle are assembled simultaneously. The production line can realize automatic entry, automatic conveying, automatic sorting, automatic taking out, and automatic entry into left and right door assembly lines of multiple material boxes, thereby reducing the transfer time of the material boxes and the input of personnel and tools during the transportation of multiple material boxes, improving production efficiency, and greatly improving the reliability, universality, and automation of the production line.

[0060] Some embodiments of the present application are mainly described by taking the production line for assembling left and right doors of a vehicle as an example. It can be understood that the production line in some embodiments of the present application can also be applied to the production of other components in a vehicle, or the production of components in other equipment different from a vehicle, as long as the corresponding assembly lines are replaced according to the actual situation.

[0061] As shown in Figure 1 and Figure 2 , the production line 1 comprises an assembly line 10, an assembly line 20, and a plurality of carrying devices 30.

[0062] The assembly line 10 is a transport line of the material boxes 40. When the empty material boxes 40 are transported along the assembly line 10, the parts for door assembly are sequentially put into the material boxes 40. The assembly line 10 has an assembly line entrance 101 and an assembly line exit 102. The assembly line entrance 101 is used for putting in the empty material boxes 40, and the assembly line exit 102 is used for transporting out the full material boxes 40. The direction from the assembly line entrance 101 to the assembly line exit 102 is the transport direction of the assembly line 10, which can be parallel to the first direction X in Figure 1 .

[0063] The assembly line 20 is used for assembling doors. The assembly line 20 has an assembly entrance 201 and an assembly exit 202. The assembly entrance 201 is used for putting in the full material boxes 40, and the assembly exit 202 is used for transporting out the empty material boxes 40. The direction from the assembly entrance 201 to the assembly exit 202 is the transport direction of the assembly line 20, which can be parallel to the first direction X in Figure 1 , and the transport direction of the assembly line 20 can be opposite to the transport direction of the assembly line 10.

[0064] The plurality of carrying devices 30 are connected between the assembly line 10 and the assembly line 20, and are configured to transfer a plurality of groups of material boxes 40 in the assembly line 10 and the assembly line 20. Each group of material boxes 40 in the plurality of groups of material boxes 40 comprises two material boxes 40 arranged side by side, and the two material boxes 40 can be arranged along the second direction Y. The second direction Y is perpendicular to the first direction X.

[0065] For example, as shown in Figure 1 and Figure 2As shown, the plurality of conveying devices 30 includes a first conveying device 301 and a second conveying device 302. The first conveying device 301 connects the assembly outlet 102 and the assembly inlet 201, and the full material box 40 transported from the assembly outlet 102 is transferred to the assembly inlet 201 by the first conveying device 301 for door assembly. The second conveying device 302 connects the assembly outlet 202 and the assembly inlet 101, and the empty material box 40 transported from the assembly outlet 202 is transferred to the assembly inlet 101 by the second conveying device 302 for assembly of the door parts.

[0066] The main transportation direction of the plurality of conveying devices 30 can be the second direction Y in the assembly line 10. Figure 1 For example, the main transportation direction of the first conveying device 301 and the main transportation direction of the second conveying device 302 are parallel to the second direction Y and opposite to each other.

[0067] It can be understood that the transportation direction of the assembly line 10, the transportation direction of the assembly line 20, and the transportation direction of the conveying device 30 can also not be limited to straight lines, but can also be curves, broken lines, or other shapes, which can be adjusted according to actual needs. In addition, the assembly line 10, the assembly line 20, and the plurality of conveying devices 30 can simultaneously transport multiple groups of material boxes 40.

[0068] In some embodiments, as shown in Figure 1 and Figure 2 The assembly line 10 includes an assembly slide 110 and an assembly area 120. The assembly slide 110 can simultaneously transport two side-by-side material boxes 40 (i.e., a group of material boxes 40). For example, the assembly line 10 can include two assembly slides 110 arranged side by side for transporting two side-by-side material boxes 40. The assembly area 120 is located at least one side of the assembly slide 110.

[0069] When the two side-by-side material boxes 40 are transported along the assembly slide 110, a plurality of parts for the subsequent assembly line 20 (such as a plurality of parts in the assembly area 120) are sequentially put into the two material boxes 40.

[0070] For example, in the process of producing a door, the parts put into the material box 40 by the assembly line 10 can include at least one of the following: door glass, door wire harness, quarter window, door lock, horn, door handle, door rubber strip, and electronic control board. Of course, the types of parts put into the material box 40 by the assembly line 10 are not limited to this, and can be adjusted according to the actual assembly needs of the door.

[0071] It can be understood that the two assembly slides 110 can also be combined into one assembly slide 110, as long as the two side-by-side material boxes 40 can be used for assembly of the corresponding assembly area 120.

[0072] In some embodiments, as shown inFigure 1 and Figure 2 As shown in FIG. 1, the assembly line 20 includes a first sub-assembly line 210, a second sub-assembly line 220, a first assembly slide 230, and a second assembly slide 240.

[0073] The first assembly slide 230 and the second assembly slide 240 extend along a first direction X and are arranged side by side, for example, along a second direction Y. The first assembly slide 230 is configured to transport a first one of the set of material boxes 40. The second assembly slide 240 is configured to transport a second one of the set of material boxes 40.

[0074] The first sub-assembly line 210 is arranged at one side of the first assembly slide 230 and is used for assembly of a left door.

[0075] The second sub-assembly line 220 is arranged at one side of the second assembly slide 240 and is used for assembly of a right door.

[0076] Either of the first sub-assembly line 210 and the second sub-assembly line 220 can include a plurality of mounting areas 250. The plurality of mounting areas 250 are used for mounting of door parts, and different mounting areas 250 correspond to different parts to be mounted.

[0077] For example, the plurality of mounting areas 250 in the first sub-assembly line 210 or the second sub-assembly line 220 are respectively used for at least one of the following: door frame trim mounting, bracket mounting, door lock mounting, door wire harness mounting, limiter mounting, glass adhesive tape mounting, window regulator mounting, door glass mounting, center pillar mounting, gluing, plastic cloth attachment, horn fixing, rear door adhesive tape mounting, and door panel mounting. Of course, the functions of the plurality of mounting areas 250 are not limited thereto and can be adjusted according to actual assembly requirements of the door.

[0078] It can be understood that the first assembly slide 230 and the second assembly slide 240 can also be the same slide, as long as the two side-by-side material boxes 40 can be used for assembly of the first sub-assembly line 210 and the second sub-assembly line 220, respectively.

[0079] In some embodiments, the handling device 30 includes a box separating device arranged close to the assembly entrance 201 or the sequential building entrance 101. The box separating device is configured to separate the two side-by-side material boxes 40 and respectively feed the separated two material boxes 40 into the two assembly slides (i.e., the first assembly slide 230 and the second assembly slide 240) or the two sequential building slides 110.

[0080] In some embodiments of the production line 1, the automatic entering, automatic carrying, automatic separating, automatic carrying out, automatic entering into the left and right door assembly lines of the material box 40 can be realized, the transfer time of the material box 40 is reduced, the personnel and tools in the transportation process of the material box 40 are reduced, the production efficiency is improved, and the reliability, universality and automation of the production line 1 are greatly improved.

[0081] The first carrying device 301 connected between the orderly building outlet 102 and the assembly inlet 201 will be taken as an example to describe the carrying device 30 in some embodiments of the present application in detail. It can be understood that the structure and function of the second carrying device 302 connected between the assembly outlet 202 and the orderly building inlet 101 are similar to those of the first carrying device 301 connected between the orderly building outlet 102 and the assembly inlet 201, and the present application will not be described again.

[0082] In some embodiments, as shown in Figure 1 and Figure 2 , the carrying device 30 comprises an input section 310, a first lifting section 320, a transfer section 330, a second lifting section 340, and a discharge section 350.

[0083] The input section 310 is connected between the orderly building line 10 (such as the orderly building outlet 102) and the first lifting section 320 and extends along the first direction X. The input section 310 is configured to separate the multiple groups of material boxes 40 transported out of the orderly building outlet 102 and sequentially input the separated multiple groups of material boxes 40 into the first lifting section 320.

[0084] For example, as shown in Figure 3 and Figure 4 , the input section 310 comprises an input chute 311 and a first stopper 312.

[0085] The input chute 311 is connected between the orderly building chute 110 and the first lifting section 320 and extends along the first direction X. The input chute 311 has an input waiting area 51, which is a part of the input chute 311 close to the first lifting section 320.

[0086] A plurality of first stoppers 312 are arranged along the second direction Y on the input chute 311, and at least part of the first stoppers 312 are located in the input waiting area 51. The plurality of first stoppers 312 are configured to control the multiple groups of material boxes 40 to be sequentially (such as according to a preset time interval) input into the first lifting section 320, thereby separating the multiple groups of material boxes 40.

[0087] In this way, by arranging the first stoppers 312, the automatic separation of the multiple groups of material boxes 40 can be realized, thereby improving the automation degree of the production line 1, reducing the labor cost, and improving the production efficiency.

[0088] In some embodiments, as shown inFigure 3 and Figure 4 As shown, the input slide 311 includes a first base 3111, a first support 3112, and a first roller conveyor 3113.

[0089] The first support 3112 is disposed on both sides of the first base 3111 in the second direction Y. The first roller conveyor 3113 is connected between the first supports 3112 on both sides of the first base 3111.

[0090] The first roller conveyor 3113 includes a plurality of first rollers. The plurality of first rollers are arranged along a first direction X and are rotatably connected between first supports 3112 on both sides of the first base 3111, so that multiple sets of material boxes 40 can move along the first roller conveyor 3113.

[0091] The plurality of first rollers can be driving rollers. Alternatively, the plurality of first rollers can also be driven rollers. Alternatively, some of the plurality of first rollers can be driving rollers and others can be driven rollers. In the case where the plurality of first rollers are driven rollers, the first roller conveyor 3113 can be an inclined roller conveyor so that the material box 40 on it slides along the first roller conveyor 3113 under its own gravity.

[0092] Here, "drive roller" refers to a roller that is directly driven by a power system (such as a motor and chain) and rotates actively to provide power. "Driven roller," in contrast to "drive roller," refers to a roller that has no power of its own and rotates passively by friction with an object or by contact with other drive rollers.

[0093] In some embodiments, the feed chute 311 may be part of the feed chute 110 to simplify the structure of the production line 1.

[0094] In some embodiments, such as Figure 3 and Figure 4 As shown, the first stopper 312 includes a first fixed base 3121, a first driving member 3122, a first transmission group 3123, a rotating base 3124, a first connecting rod 3125, a first limiting member 3126, and a second limiting member 3127.

[0095] The first fixed seat 3121 is located on the side of the first base 3111 away from the first roller conveyor 3113 (as shown below).

[0096] The first driving member 3122 is disposed on the first fixed base 3121 and configured to provide driving force. For example, the first driving member 3122 can be a cylinder, a hydraulic cylinder, an electric actuator, etc., and this application is not limited to these.

[0097] The rotating seat 3124 is disposed below the input chute 311. For example, the rotating seat 3124 is disposed on the side (e.g., the upper side) of the first base 3111 close to the first roller 3113 and below the first roller 3113.

[0098] The first connecting rod 3125 extends along the first direction X, and a center of the first connecting rod 3125 in the first direction X is rotatably connected with the rotating seat 3124.

[0099] The first end of the first transmission group 3123 is connected with the first driving member 3122, and the second end of the first transmission group 3123 is connected with the first end of the first connecting rod 3125 in the first direction X. For example, the first transmission group 3123 can include a plurality of hingedly connected connecting rods.

[0100] The first limiting member 3126 is disposed on the first end of the first connecting rod 3125 in the first direction X and extends towards the direction (e.g., upwards) close to the input chute 311. In the first direction X, the first limiting member 3126 can be located between the input waiting area 51 and the first lifting section 320. The first limiting member 3126 is configured to control the material box 40 in the input waiting area 51 to move out of the input waiting area 51.

[0101] It can be understood that, in the first direction X, the first limiting member 3126 can also be located in the input waiting area 51, as long as the first limiting member 3126 is close to the first lifting section 320 and can control the material box 40 in the input waiting area 51 to move out of the input waiting area 51.

[0102] The second limiting member 3127 is disposed on the second end of the first connecting rod 3125 in the first direction X and is located on the side (e.g., the upper side) of the first connecting rod 3125 close to the input chute 311. In the first direction X, the second limiting member 3127 can be located on the side of the input waiting area 51 away from the first lifting section 320. The second limiting member 3127 is configured to control the material box 40 outside the input waiting area 51 to enter the input waiting area 51 and to push the material box 40 in the input waiting area 51 to enter the first lifting section 320.

[0103] In some embodiments, the first stopper 312 has a first state and a second state.

[0104] In the first state, the first end of the first connecting rod 3125 is higher than the second end of the first connecting rod 3125, the first limiting member 3126 is raised to a position higher than the first conveying surface, and the second limiting member 3127 is lowered to a position lower than the first conveying surface. In this case, the material box 40 on the input chute 311 can enter the input waiting area 51.

[0105] In the second state, the first end of the first link 3125 is lower than the second end of the first link 3125, the first stopper 3126 is lowered to a position lower than the first conveying surface, and the second stopper 3127 is raised to a position higher than the first conveying surface. In this case, the second stopper 3127 can block the material box 40 outside the input waiting area 51 from entering the input waiting area 51, and the second stopper 3127 can also push the material box 40 inside the input waiting area 51 to enter the first lifting section 320.

[0106] When the first stopper 3126 is higher than the first conveying surface, the first stopper 3126 can abut against the material box 40 on the input chute 311 to block the material box 40 from continuing to advance. When the first stopper 3126 is lower than the first conveying surface, the first stopper 3126 cannot block the material box 40 on the input chute 311.

[0107] When the second stopper 3127 is higher than the first conveying surface, the second stopper 3127 can abut against the material box 40 outside the input waiting area 51 to block the material box 40 from continuing to advance, and can also abut against the material box 40 inside the input waiting area 51 to push the material box 40 inside the input waiting area 51 to move. When the second stopper 3127 is lower than the first conveying surface, the second stopper 3127 cannot block the material box 40 on the input chute 311.

[0108] Here, the "first conveying surface" can be understood as a plane (such as a plane formed by the contact surface between the plurality of first rollers in the input chute 311 and the material box 40) that is flush with the bottom surface of the material box 40 when the material box 40 is transported on the input chute 311.

[0109] It can be understood that the first driving member 3122 can drive the first link 3125 to rotate clockwise or counterclockwise around the rotating seat 3124 through the first transmission set 3123, so as to realize the first state and the second state of the first stopper 312.

[0110] In addition, since the input section 310 can simultaneously transport two side-by-side material boxes 40 (i.e., a group of material boxes 40), the input section 310 can include two first stoppers 312, as shown in Figure 4 The two first stoppers 312 can share a first fixed seat 3121, a first driving member 3122, and a first transmission set 3123, so as to simplify the structure of the input section 310.

[0111] In some embodiments, as shown in Figure 3As shown, the first limiting member 3126 can include a body 31261 and a first blocking portion 31262. The body 31261 is connected with the first end of the first connecting rod 3125 and protrudes upward. The first blocking portion 31262 is arranged on the side of the body 31261 close to the build line 10, and the first blocking portion 31262 can abut against the side of the material box 40 close to the first lifting section 320 in the input waiting area 51 to block the material box 40 in the input waiting area 51. For example, the first blocking portion 31262 can be an elastic member such as a rubber block or a spring to provide buffering and avoid the first limiting member 3126 and the material box 40 from colliding and causing damage to the material box 40 or the first limiting member 3126.

[0112] In some embodiments, as Figure 5 As shown, the second limiting member 3127 includes a supporting portion 31271, a transition portion 31272, and a connecting portion 31273.

[0113] The supporting portion 31271 is arranged at the second end of the first connecting rod 3125 and extends along a third direction Z. The supporting portion 31271 is configured to block the material box 40 outside the input waiting area 51 from entering the input waiting area 51. The third direction Z is perpendicular to the first direction X and the second direction Y, and the first direction X, the second direction Y, and the third direction Z in the present application are all bidirectional directions.

[0114] The transition portion 31272 is connected with the end of the supporting portion 31271 away from the first connecting rod 3125. The transition portion 31272 is in a circular arc shape to facilitate the separation of adjacent two material boxes 40 when the second limiting member 3127 is raised, and also to avoid damaging the material boxes 40 in the process of separating the material boxes 40.

[0115] The first end of the connecting portion 31273 is connected with the transition portion 31272, and the second end (i.e., the end of the connecting portion 31273 away from the transition portion 31272) of the connecting portion 31273 extends toward the first connecting rod 3125 away from the transition portion 31272 and is connected with the first connecting rod 3125. The connecting portion 31273 is configured to push the material box 40 in the input waiting area 51 to move.

[0116] When the second limiting member 3127 is raised, the connecting portion 31273 arranged obliquely can abut against the side of the material box 40 in the input waiting area 51 away from the first lifting section 320, and provide a pushing force to the material box 40 through the inclined surface thereof to move the material box 40 in the input waiting area 51 forward.

[0117] In this way, the stability and reliability of the input section 310 for transporting the material box 40 can be improved, and the plurality of first rollers in the input waiting area 51 do not need to be driven rollers, which simplifies the structure of the input slide 311 and reduces the cost.

[0118] The first stopper 312 in some embodiments of the present application can simultaneously act on multiple groups of material boxes 40 to achieve the separation of multiple groups of material boxes 40, thereby reducing the control components required for the separation of material boxes, reducing the cost of the production line 1, and improving the reliability of the production line 1.

[0119] In some embodiments, as shown in Figure 3 and Figure 4 , the feeding section 310 further comprises a plurality of first sensors 313. The plurality of first sensors 313 can be respectively arranged in the feeding waiting area 51 and outside the feeding waiting area 51. The plurality of first sensors 313 are configured to detect whether there is a material box 40 at the corresponding position.

[0120] For example, the plurality of first sensors 313 can be one or more of a travel switch, a photoelectric opposite switch, or a proximity switch, without limitation in the present application. For example, at least one of the plurality of first sensors 313 can be a travel switch. When the material box 40 moves to the travel switch, the material box 40 touches the travel switch, thereby triggering the first stopper 312 to switch the state, thereby controlling the separation and transportation of the material box 40 in the feeding section 310.

[0121] As shown in Figure 1 and Figure 2 , the first lifting section 320 is connected between the feeding section 310 and the transfer section 330, and is configured to transport the multiple groups of material boxes 40 transported from the feeding section 310 along the third direction Z.

[0122] For example, as shown in Figure 6 , the first lifting section 320 comprises a first lifting bracket 321, a first lifting driving assembly 322, and a first tray 323.

[0123] The first lifting bracket 321 extends along the third direction Z.

[0124] The first lifting driving assembly 322 is arranged on the first lifting bracket 321 and is in driving connection with the first tray 323. The first tray 323 is configured to move to a first position or a second position along the third direction Z under the driving of the first lifting driving assembly 322. The first position is lower than the second position.

[0125] The “first position” can be a position lower than or flush with the first transportation surface. When the first tray 323 is in the first position, a group of material boxes 40 in the feeding waiting area 51 can smoothly move onto the first tray 323.

[0126] The "second position" can be a position higher than or flush with the second conveying surface. When the first tray 323 is in the second position, the group of material boxes 40 on the first tray 323 can be smoothly moved to the transfer section 330. The transfer section 330 and the second conveying surface will be described later.

[0127] For example, when the first sensor 313 in the input waiting area 51 detects that there is a group of material boxes 40 in the input waiting area 51, the first lifting driving assembly 322 can be configured to drive the first tray 323 to move to the first position in the third direction Z.

[0128] The first tray 323 is configured to accommodate a group of material boxes 40. The first tray 323 is provided with a driving roller, which can rotate to carry the material boxes 40 on the first tray 323 out of the first tray 323.

[0129] It should be noted that when the first tray 323 is in the first position, the group of material boxes 40 in the input waiting area 51 enters the first tray 323 from the side of the first tray 323 close to the input waiting area 51 (i.e. the side of the first tray 323 in the first direction X). When the first tray 323 is in the second position, the group of material boxes 40 on the first tray 323 can be carried out of the first tray 323 from the side of the first tray 323 close to the transfer section 330 (i.e. the side of the first tray 323 in the second direction Y).

[0130] In some embodiments, the first lifting driving assembly 322 can include a motor, a plurality of chain wheels, a chain, and a guide rail. The motor is connected with the chain wheels for driving the chain wheels to rotate. The plurality of chain wheels are arranged on the first lifting support 321, and the plurality of chain wheels are connected by the chain. The first tray 323 is connected with the chain. Moreover, the first lifting support 321 includes a guide rail extending in the third direction Z, and the first tray 323 is slidably connected with the guide rail.

[0131] In this way, the first tray 323 can slide along the guide rail in the third direction Z under the driving of the chain, so as to move to the first position or the second position.

[0132] Of course, the first lifting driving assembly 322 can also adopt other structures with lifting function (such as a scissor mechanism), and the present application is not limited thereto.

[0133] In some embodiments, the first lifting section 320 can further include a first group of sensors and a second group of sensors.

[0134] The first group of sensors are arranged on the first lifting support 321 and correspond to the first position. The first group of sensors are configured to detect whether the first tray 323 moves to the first position, and to detect whether there are material boxes 40 on the first tray 323.

[0135] The second set of sensors is disposed on the first lifting bracket 321 and corresponds to the second position. The second set of sensors is configured to detect whether the first tray 323 moves to the second position and whether there is a group of material boxes 40 on the first tray 323.

[0136] For example, when the first set of sensors detects that the first tray 323 moves to the first position, the first lifting driving assembly 322 is closed to stop the movement of the first tray 323. When the second set of sensors detects that the first tray 323 moves to the second position, the first lifting driving assembly 322 is closed to stop the movement of the first tray 323.

[0137] When the first set of sensors detects that there is a group of material boxes 40 on the first tray 323, the first lifting driving assembly 322 can drive the first tray 323 to move to the second position in the third direction Z.

[0138] When the second set of sensors detects that the first tray 323 moves to the second position and there is a group of material boxes 40 on the first tray 323, the driving roller on the first tray 323 can rotate to drive the group of material boxes 40 to move to the transfer section 330.

[0139] When the second set of sensors detects that there is no material box 40 on the first tray 323 in the second position, and the first sensor 313 in the input waiting area 51 detects that there is a group of material boxes 40 in the input waiting area 51, the first lifting driving assembly 322 can drive the first tray 323 to move to the first position in the third direction Z to transport the material boxes 40.

[0140] The first set of sensors and the second set of sensors can be one or more of a travel switch, a photoelectric opposite switch, or a proximity switch, which is not limited in the present application. The first set of sensors or the second set of sensors can include a plurality of photoelectric sensors to realize a plurality of functions such as position detection, speed detection, and limit alarm.

[0141] As shown in Figure 1 and Figure 2 The transfer section 330 is connected between the first lifting section 320 and the second lifting section 340 and extends in the second direction Y. The transfer section 330 is configured to transport a plurality of groups of material boxes 40 transported from the first lifting section 320 in the second direction Y.

[0142] For example, as shown in Figure 7 The transfer section 330 includes a transfer slide 331, a second stopper 332, and a third stopper 333.

[0143] The transfer chute 331 is connected between the first lifting section 320 and the second lifting section 340 and extends along the second direction Y. The transfer chute 331 has a transfer waiting area 52, which is a portion of the transfer chute 331 close to the second lifting section 340.

[0144] The second stopper 332 is disposed on the transfer chute 331 and located between the transfer waiting area 52 and the second lifting section 340. The second stopper 332 is configured to control a group of the material boxes 40 in the transfer waiting area 52 to enter the second lifting section 340.

[0145] The third stopper 333 is disposed on the transfer chute 331 and located on a side of the transfer waiting area 52 away from the second lifting section 340. The third stopper 333 is configured to control a group of the material boxes 40 outside the transfer waiting area 52 to enter the transfer waiting area 52.

[0146] In some embodiments, the transfer chute 331 can include a second bracket 3311 and a second roller way 3312.

[0147] The second bracket 3311 extends along the second direction Y, and the second roller way 3312 is connected with the second bracket 3311. The second roller way 3312 includes a plurality of second rollers arranged along the second direction Y and rotatably disposed on the second bracket 3311. The plurality of second rollers can be driving rollers, and the material boxes 40 on the transfer chute 331 can be driven by the plurality of second rollers to move along the second direction Y.

[0148] In some embodiments, the transfer section 330 has a third state, a fourth state, and a fifth state.

[0149] In the third state, the second stopper 332 is open, and the third stopper 333 is closed. In this case, the first group of the material boxes 40 transported from the first lifting section 320 can enter the transfer waiting area 52 and be blocked by the second stopper 332, thereby stopping in the transfer waiting area 52.

[0150] In the fourth state, the second stopper 332 is open, and the third stopper 333 is open. In this case, the second group of the material boxes 40 transported from the first lifting section 320 are blocked by the third stopper 333 outside the transfer waiting area 52.

[0151] In the fifth state, the second stopper 332 is closed, and the third stopper 333 is open. The first group of the material boxes 40 in the transfer waiting area 52 enters the second lifting section 340, and the second group of the material boxes 40 outside the transfer waiting area 52 remains stationary.

[0152] It can be understood that, since the transfer section 330 can simultaneously transport two side-by-side material boxes 40, the transfer section 330 can include two second stoppers 332 spaced apart along the first direction X and two third stoppers 333 spaced apart along the first direction X.

[0153] In some embodiments, as shown in Figure 8 and Figure 9 The second stopper 332 includes a second fixed seat 3321, a second driving member 3322, a second transmission group 3323, a second connecting rod 3324, and a second blocking part 3325.

[0154] The second fixed seat 3321 is arranged below the transfer chute 331. For example, the second fixed seat 3321 is arranged on the second support 3311 and below the second roller track 3312.

[0155] The second driving member 3322 is arranged on the side (e.g., the upper side) of the second fixed seat 3321 away from the transfer chute 331 (e.g., the second roller track 3312). The second driving member 3322 is configured to provide a driving force. For example, the second driving member 3322 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, without being limited thereto.

[0156] The first end of the second connecting rod 3324 is rotatably connected to the side (e.g., the upper side) of the second fixed seat 3321 close to the transfer chute 331 (e.g., the second roller track 3312), and the second end of the second connecting rod 3324 extends towards the direction close to the transfer chute 331 (e.g., upwards).

[0157] For example, as shown in Figure 9 The second connecting rod 3324 includes a first extension 33241, a second extension 33242, and a third extension 33243 connected in sequence. The first extension 33241 extends along the third direction Z and is rotatably connected to the second fixed seat 3321. The second extension 33242 extends along the second direction Y, and the third extension 33243 extends along the third direction Z.

[0158] The second transmission group 3323 is rotatably arranged on the second fixed seat 3321, the first end of the second transmission group 3323 is connected to the second driving member 3322, and the second end of the second transmission group 3323 is connected to the second connecting rod 3324. For example, the second transmission group 3323 can include a plurality of hingedly connected connecting rods, and the second end of the second transmission group 3323 is connected between the second extension 33242 and the third extension 33243.

[0159] The second blocking part 3325 is arranged at the second end of the second connecting rod 3324 and faces the first lifting section 320. The second blocking part 3325 is configured to abut against the material boxes 40 in the transfer waiting area 52 to block a group of the material boxes 40 in the transfer waiting area 52. For example, the second blocking part 3325 can be an elastic member such as a rubber block or a spring to provide buffering and avoid damage to the material boxes 40 caused by impact.

[0160] When the second stopper 332 is closed, the second blocking part 3325 is lower than the second conveying surface. In this case, a group of the material boxes 40 in the transfer waiting area 52 can be transported out of the transfer waiting area 52.

[0161] When the second stopper 332 is opened, the second blocking part 3325 is higher than the second conveying surface. In this case, the second blocking part 3325 abuts against the side of the material boxes 40 in the transfer waiting area 52 close to the second lifting section 340 to prevent the material boxes 40 from being transported out of the transfer waiting area 52.

[0162] Here, the "second conveying surface" can be understood as a plane that is flush with the bottom surface of the material boxes 40 when the material boxes 40 are transported on the transfer slide 331 (e.g., a plane formed by the contact surfaces of the plurality of second rollers in the transfer slide 331 and the material boxes 40).

[0163] It can be understood that the second driving member 3322 can pull the second connecting rod 3324 to rotate by a first preset angle around the first direction X as the rotation axis through the second transmission group 3323, so as to realize the opening and closing of the second stopper 332.

[0164] In some embodiments, as shown in FIG. 3B, the third stopper 333 includes a third fixed seat 3331, a third driving member 3332, a third transmission group 3333, a third connecting rod 3334, and a first guide member 3335. Figure 10

[0165] The third fixed seat 3331 is arranged below the transfer slide 331. For example, the third fixed seat 3331 is arranged on the second support 3311 and located below the second roller way 3312.

[0166] The third driving member 3332 is arranged on the third fixed seat 3331 and is configured to provide a driving force. For example, the third driving member 3332 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, and the present application is not limited thereto.

[0167] The first guide member 3335 is arranged on the third fixed seat 3331 and located at the side (e.g., the upper side) of the third driving member 3332 close to the transfer slide 331 (e.g., the second roller way 3312).

[0168] The third transmission group 3333 can include a plurality of interconnected connecting rods.​

[0169] The third link 3334 extends in the third direction Z and is slidably disposed on the first guide member 3335. The first end of the third link 3334 is connected to the third drive member 3332 via the third transmission assembly 3333, and the second end of the third link 3334 passes through the first guide member 3335. The second end of the third link 3334 is adapted to abut against the material box 40 outside the transfer waiting area 52 to prevent the material box 40 from entering the transfer waiting area 52. For example, the second end of the third link 3334 is provided with a notch 3336 to facilitate abutment against the bottom edge of the material box 40 to prevent the material box 40 from entering.

[0170] When the third stopper 333 is closed, the second end of the third link 3334 is lower than the second transport surface. In this case, a set of material boxes 40 outside the transfer waiting area 52 can enter the transfer waiting area 52.

[0171] When the third stopper 333 is opened, the second end of the third link 3334 is higher than the second transport surface. In this case, the second end of the third link 3334 abuts against the side of the material box 40 outside the transfer waiting area 52 that is close to the transfer waiting area 52, so as to prevent the material box 40 from entering the transfer waiting area 52.

[0172] It is understandable that the third drive unit 3332 can drive the third link 3334 to retract or extend through the third transmission group 3333, so as to realize the opening and closing of the third stop 333.

[0173] In some embodiments, such as Figure 7 As shown, the transfer section 330 also includes multiple second sensors 334. These second sensors 334 can be respectively located within the transfer waiting area 52 and outside the transfer waiting area 52. The multiple second sensors 334 are configured to detect the presence of a material box 40 at a corresponding location.

[0174] For example, the multiple second sensors 334 can be one or more of limit switches, photoelectric switches, or proximity switches, and this application does not impose any restrictions on this. The relevant content of the second sensor 334 is similar to that of the first sensor 313, and will not be repeated here.

[0175] like Figure 1 and Figure 2 As shown, the second lifting section 340 is connected between the transfer section 330 and the discharge section 350, and is configured to transport multiple sets of material boxes 40 transported from the transfer section 330 along the third direction Z.

[0176] For example, the second lifting section 340 includes a second lifting bracket, a second lifting drive assembly, and a second tray.

[0177] The structure and function of the second lifting section 340 are similar to those of the first lifting section 320, and thus are not described herein again.

[0178] When the second tray is in the second position, a group of material boxes 40 in the transfer waiting area 52 can enter the second tray from the side of the second tray close to the transfer waiting area 52, i.e., the side of the second tray in the second direction Y. When the second tray is in the first position, a group of material boxes 40 on the second tray are transferred out of the second tray from the side of the second tray close to the outfeed section 350, i.e., the side of the second tray in the second direction Y.

[0179] As shown in Figure 1 and Figure 2 , the outfeed section 350 is connected between the second lifting section 340 and the assembly line 20, such as the assembly inlet 201, and extends along the second direction Y. The above-described box separating device is provided in the outfeed section 350, which is configured to transport the groups of material boxes 40 transferred out of the second lifting section 340 along the second direction Y.

[0180] For example, as shown in Figure 11 , the outfeed section 350 includes an outfeed chute 351, a box stopper 352, a box blocker 353, and a turning conveyor 354. The above-described box separating device includes the box stopper 352 and the box blocker 353.

[0181] The outfeed chute 351 is connected between the second lifting section 340 and the two assembly chutes and extends along the second direction Y. The outfeed chute 351 has an outfeed waiting area 53, which is a portion of the outfeed chute 351 close to the assembly inlet 201.

[0182] The box stopper 352 is provided in the outfeed chute 351 and located outside the outfeed waiting area 53. The box stopper 352 is configured to separate two material boxes 40 in a group of material boxes 40. For example, when a first material box 40 in a group of material boxes 40 passes the box stopper 352, the box stopper 352 is opened to stop a second material box 40 in the group of material boxes 40 from moving on, so that the two material boxes 40 in the group of material boxes 40 are separated. The structure and function of the box stopper 352 are the same as those of the third stopper 333 described above, and thus are not described herein again.

[0183] The box blocker 353 is provided in the outfeed chute 351 and located in the outfeed waiting area 53. The box blocker 353 divides the outfeed waiting area 53 into a first sub-waiting area 531 and a second sub-waiting area 532. The box blocker 353 is configured to separate two material boxes 40 in the outfeed waiting area 53 by a preset distance, so that the two material boxes 40 are respectively fed into the first assembly chute 230 and the second assembly chute 240.

[0184] The transfer conveyor 354 is located below the outfeed chute 351 in the outfeed waiting area 53, and is configured to transport two material boxes 40 in the outfeed waiting area 53 to the assembly line 20 along the first direction X.

[0185] In some embodiments of the present application, by providing the box separation stopper 352 and the box separation blocker 353, two side-by-side material boxes 40 (such as the material boxes 40 located on the left and right sides) can be separated, so that the two material boxes 40 can be simultaneously fed to the corresponding assembly line 20 for assembly, thereby reducing manual feeding and improving production efficiency.

[0186] In some embodiments, as shown in Figure 12 The outfeed chute 351 includes a second base 3511, a third support 3512, and a third roller bed 3513.

[0187] The third support 3512 is arranged on both sides of the second base 3511 in the first direction X, and the third roller bed 3513 is connected between the third supports 3512 on both sides of the second base 3511. As shown in Figure 11 The third roller bed 3513 includes a first sub-roller bed 3514 and a second sub-roller bed 3515.

[0188] The first sub-roller bed 3514 and the second sub-roller bed 3515 each include a plurality of third rollers. The plurality of third rollers in the first sub-roller bed 3514 are driving rollers to actively transport the material boxes 40 on the first sub-roller bed 3514. The plurality of third rollers in the second sub-roller bed 3515 are driven rollers, and the outfeed waiting area 53 is located on the second sub-roller bed 3515.

[0189] In this way, when the first sub-roller bed 3514 transports the material boxes 40 to the second sub-roller bed 3515, the material boxes 40 can stop in the outfeed waiting area 53 under the action of frictional resistance.

[0190] In some embodiments, as shown in Figure 13 The box separation blocker 353 includes a first mounting seat 3531, a second mounting seat 3532, a fixed plate 3533, a box separation driving member 3534, a transmission member 3535, and two blocking members 3536.

[0191] The first mounting seat 3531 and the second mounting seat 3532 are respectively arranged on both sides of the outfeed chute 351 in the first direction X. For example, the first mounting seat 3531 and the second mounting seat 3532 are respectively connected with the third supports 3512 on both sides of the second base 3511.

[0192] The fixed plate 3533 is connected between the first mounting seat 3531 and the second mounting seat 3532, and extends along the first direction X.

[0193] The bin driving member 3534 is arranged on the first mounting base 3531 and is configured to provide a driving force. For example, the bin driving member 3534 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, and the present application is not limited thereto.

[0194] The transmission member 3535 is in transmission connection with the bin driving member 3534, and the transmission member 3535 is slidably arranged between the first mounting base 3531 and the second mounting base 3532. The transmission member 3535 is movable along the first direction X and is arranged in spaced apart relation with the fixed plate 3533.

[0195] The two blocking members 3536 are arranged in spaced apart relation along the first direction X. Each blocking member 3536 extends substantially along the third direction Z (e.g., upwardly) and is rotatably connected with the fixed plate 3533. A first end (e.g., lower end) of the blocking member 3536 along the third direction Z is connected with the transmission member 3535, and a second end (e.g., upper end) of the blocking member 3536 along the third direction Z is adapted to abut against the material bin 40 in the discharge waiting area 53, so as to stop the material bin 40 in the second sub-waiting area 532.

[0196] The blocking member 3536 can rotate a second preset angle about the second direction Y as the rotation axis, with the position where the blocking member 3536 is connected with the fixed plate 3533 as the center, under the driving of the bin driving member 3534.

[0197] The bin blocking device 353 has a first blocking state and a second blocking state.

[0198] In the first blocking state, the second ends of the two blocking members 3536 are lower than the discharge conveying surface. In this case, the material bin 40 can enter the first sub-waiting area 531 through the bin blocking device 353.

[0199] In the second blocking state, the second ends of the two blocking members 3536 are higher than the discharge conveying surface. In this case, the two blocking members 3536 can abut against the material bin 40 to block the material bin 40 from moving along the second direction Y, so as to stop the material bin 40 in the second sub-waiting area 532.

[0200] Here, the “discharge conveying surface” can be understood as a plane (e.g., a plane formed by the contact surface between the plurality of third rollers in the discharge chute 351 and the material bin 40) that is flush with the bottom surface of the material bin 40 when the material bin 40 is conveyed on the discharge chute 351.

[0201] It can be understood that the bin driving member 3534 can drive the two blocking members 3536 to rotate a second preset angle through the transmission member 3535, so as to change the second ends of the blocking members 3536 from being lower than the discharge conveying surface to being higher than the discharge conveying surface or from being higher than the discharge conveying surface to being lower than the discharge conveying surface.

[0202] In some embodiments, as shown in FIG. 3A, the bin blocking device 353 can be arranged on the discharge chute 351. Figure 14As shown, the blocking member 3536 includes a first sub-blocking part 35361 and a second sub-blocking part 35362.

[0203] The first sub-blocking part 35361 is rotatably disposed on the fixed plate 3533. The first end of the first sub-blocking part 35361 is connected to the transmission member 3535, and the second end of the first sub-blocking part 35361 is connected to the second sub-blocking part 35362.

[0204] The second sub-blocking part 35362 extends along a third direction Z, and the extension direction of the second sub-blocking part 35362 (such as the third direction Z) forms a preset angle with the extension direction of the first sub-blocking part 35361. The second sub-blocking part 35362 can abut against the side wall of the material box 40.

[0205] In this way, by setting up the bent blocking member 3536, the two material boxes in the discharge waiting area 53 can be spaced at a preset distance, while buffering the impact force when the blocking member 3536 comes into contact with the material box 40, avoiding damage to both and improving the reliability of the box divider blocking device 353.

[0206] In some embodiments, such as Figure 15 and Figure 16 As shown, the steering conveyor 354 includes a third mounting base 3541, a support assembly 3542, a conveying drive component 3543, a lifting base 3544, a power transmission assembly 3545, multiple mounting brackets 3546, and multiple conveying assemblies 3547.

[0207] The third mounting base 3541 is located below the discharge chute 351 within the discharge waiting area 53.

[0208] A support assembly 3542 is disposed on the third mounting base 3541 and connected between the lifting base 3544 and the third mounting base 3541. The support assembly 3542 is used to support the lifting base 3544. For example, the support assembly 3542 may include a plurality of connecting columns or connecting seats that are hinged to each other.

[0209] The lifting seat 3544 is located on the side of the support assembly 3542 away from the third mounting seat 3541 (as above), and is configured to move along the third direction Z under the drive of an external force.

[0210] Multiple mounting brackets 3546 are arranged on the side of the lifting base 3544 away from the third mounting base 3541 (as shown above).

[0211] Multiple conveying assemblies 3547 are arranged at intervals along the second direction Y and are respectively mounted on multiple mounting frames 3546. Any one of the conveying assemblies 3547 extends along the first direction X. The multiple conveying assemblies 3547 are configured to transport two material boxes 40 in the discharge waiting area 53 along the first direction X.

[0212] The conveying drive 3543 is disposed on one side (e.g., the lower side) of the lifting seat 3544 close to the third mounting seat 3541, and is drivingly connected to the plurality of conveying assemblies 3547 through a power transmission assembly 3545. The conveying drive 3543 is configured to provide driving force to drive the plurality of conveying assemblies 3547 to convey the material boxes 40 through the power transmission assembly 3545. For example, the conveying drive 3543 can be an electric motor, but the present application is not limited thereto.

[0213] The conveying device 354 has a first conveying state and a second conveying state.

[0214] In the first conveying state, the conveying drive 3543 is off, the lifting seat 3544 is in the first lifting position, and the plurality of conveying assemblies 3547 are below the outfeed transport surface. In this case, the two material boxes 40 in the outfeed waiting area 53 are stationary.

[0215] In the second conveying state, the conveying drive 3543 is on, the lifting seat 3544 is moved to the second lifting position along the third direction Z (e.g., upward), the second lifting position is higher than the first lifting position, and at least part of the plurality of conveying assemblies 3547 are above the outfeed transport surface. In this case, the plurality of conveying assemblies 3547 lift the two material boxes 40 in the outfeed waiting area 53, so that the two material boxes 40 on the plurality of conveying assemblies 3547 can be moved to the assembly line 20 along the first direction X under the driving of the conveying drive 3543.

[0216] It should be noted that the lifting seat 3544 can be lifted by a linear driving element such as a hydraulic rod, an air cylinder, etc., so as to switch between the first lifting position and the second lifting position. Of course, the lifting seat 3544 can also be lifted by a motor cooperating with a screw mechanism or a cam structure, but the present application is not limited thereto.

[0217] In some embodiments, as shown in Figure 16 The plurality of conveying assemblies 3547 can include four conveying assemblies 3547. Each two conveying assemblies 3547 correspond to one material box 40 in a set of material boxes 40.

[0218] As shown in Figure 15As shown, each conveying assembly 3547 includes a plurality of transmission wheels 35471 and a belt 35472. The plurality of transmission wheels 35471 are spaced apart along the first direction X on the mounting frame 3546, and the belt 35472 is sleeved on the plurality of transmission wheels 35471. In this case, the conveying drive 3543 is in transmission connection with the plurality of transmission wheels 35471 through the power transmission assembly 3545. In this way, the conveying drive 3543 can drive the plurality of transmission wheels 35471 to rotate through the power transmission assembly 3545, so as to drive the belt 35472 to rotate, thereby driving the material box 40 on the belt 35472 to move along the first direction X.

[0219] In some embodiments, as shown, Figure 15 The turning conveyor 354 further includes a third limiting piece 3548. The third limiting piece 3548 is arranged between the lifting seat 3544 and the third mounting seat 3541, and is configured to abut against one side (e.g., the lower side) of the lifting seat 3544 in the third direction Z when the turning conveyor 354 is in the first conveying state, so as to limit the lifting seat 3544 in the third direction Z.

[0220] In some embodiments, as shown, Figure 15 The turning conveyor 354 further includes a fourth limiting piece 3549. The fourth limiting piece 3549 is arranged on the third mounting seat 3541, and is close to one end (e.g., the end close to the assembly line 20) of the third mounting seat 3541 in the first direction X. The fourth limiting piece 3549 is configured to abut against one end of the lifting seat 3544 in the first direction X when the turning conveyor 354 is in the first conveying state, so as to limit the lifting seat 3544 in the first direction X.

[0221] In some embodiments, the discharging section 350 further includes a third sensor, a fourth sensor, and a fifth sensor.

[0222] The third sensor is arranged close to the box stopping device 352, and is configured to detect whether there is a material box 40 passing through the box stopping device 352.

[0223] The fourth sensor is arranged in the first sub-waiting area 531, and is configured to detect whether there is a material box 40 in the first sub-waiting area 531.

[0224] The fifth sensor is arranged in the second sub-waiting area 532, and is configured to detect whether there is a material box 40 in the second sub-waiting area 532.

[0225] The third sensor, the fourth sensor, and the fifth sensor can be one or more of a travel switch, a photoelectric opposite-acting switch, or a proximity switch, and the present application does not limit the same. The third sensor, the fourth sensor, and the fifth sensor are similar to the first sensor 313, and will not be described here again.

[0226] In some embodiments, as shown in FIG. 35, the discharge section 350 further comprises a plurality of fourth stoppers 357. The plurality of fourth stoppers 357 are respectively arranged on both sides of the discharge chute 351 in the first direction X, and are configured to control the distance between two adjacent groups of material boxes 40 to prevent collision between the two groups of material boxes 40. Figure 11

[0227] As shown in FIG. 36, the fourth stopper 357 comprises a fourth fixed seat 3571, a fourth driving member 3572, a fourth transmission group 3573, a fourth connecting rod 3574, and a second guide 3575. Figure 12

[0228] The fourth fixed seat 3571 is arranged on one side of the discharge chute 351.

[0229] The fourth driving member 3572 is arranged on the fourth fixed seat 3571 and is configured to provide a driving force. For example, the fourth driving member 3572 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod, without being limited thereto.

[0230] The second guide 3575 is arranged on the fourth fixed seat 3571 and is located on the side of the fourth driving member 3572 close to the discharge chute 351.

[0231] The fourth transmission group 3573 can comprise a plurality of interconnected connecting rods.

[0232] The fourth connecting rod 3574 extends in the first direction X and is slidably arranged on the second guide 3575. The first end of the fourth connecting rod 3574 is connected to the fourth driving member 3572 through the fourth transmission group 3573, and the second end of the fourth connecting rod 3574 passes through the second guide 3575. The fourth connecting rod 3574 is movable in the first direction X, so that the second end of the fourth connecting rod 3574 can abut against the material box 40 on the discharge chute 351 to block the material box 40 from continuing to advance.

[0233] The fourth stopper 357 comprises a sixth state and a seventh state.

[0234] In the sixth state, the fourth driving member 3572 is closed, and the fourth connecting rod 3574 is retracted. In this case, the fourth connecting rod 3574 is misaligned with the material box 40 on the discharge chute 351, and the material box 40 on the discharge chute 351 can pass through the fourth stopper 357.

[0235] ​​In the seventh state, the fourth driving member 3572 is activated, and the fourth connecting rod 3574 moves away from the middle of the discharge chute 351. In this case, the fourth connecting rod 3574 can abut against the group of material boxes 40 on the discharge chute 351 to prevent the group of material boxes 40 on the discharge chute 351 from moving in the second direction Y. In this way, the two groups of material boxes 40 on the discharge chute 351 can be separated to facilitate subsequent sorting.

[0236] It can be understood that the fourth driving member 3572 can drive the fourth connecting rod 3574 to slide in the first direction X through the fourth transmission group 3573.

[0237] The process of transporting the material boxes 40 by the first conveying device 301 in some embodiments of the present application is described in detail below.

[0238] First, the two groups of material boxes 40 that have completed the construction work enter the input section 310 from the construction outlet 102. The first stopper 312 is in the first state. At this time, the first limiting member 3126 in the first stopper 312 rises to a position higher than the first conveying surface, and the second limiting member 3127 descends to a position lower than the first conveying surface. The first limiting member 3126 blocks the first group of material boxes 40 from entering the first lifting section 320. At this time, the first group of material boxes 40 is in the input waiting area 51.

[0239] Then, the first stopper 312 switches to the second state. At this time, the first limiting member 3126 in the first stopper 312 descends to a position lower than the first conveying surface, and the second limiting member 3127 rises to a position higher than the first conveying surface. The first limiting member 3126 no longer blocks the first group of material boxes 40, and the first group of material boxes 40 slides into the first tray 323 (which is in the first position at this time) of the first lifting section 320 under the action of gravity and the pushing of the second limiting member 3127. The second limiting member 3127 blocks the second group of material boxes 40 behind the first group of material boxes 40, preventing the second group of material boxes 40 from entering the first lifting section 320 along with the first group of material boxes 40, thereby completing the sorting operation of the two groups of material boxes 40 at the input section 310 and achieving automatic sorting.

[0240] After the first group of sensors in the first lifting section 320 detects that the first group of material boxes 40 slides into the first tray 323, the first tray 323 rises towards the second position. At this time, the first stopper 312 can switch to the first state, and the second group of material boxes 40 can enter the input waiting area 51.

[0241] When the second group of sensors in the first lifting section 320 detects that the first tray 323 is raised to the second position, the first tray 323 stops rising, and the drive rollers in the first tray 323 operate to move the first group of material boxes 40 from the first tray 323 to the transfer section 330. The second rollers on the transfer slide 331 operate to move the first group of material boxes 40 toward the transfer waiting area 52. In this process, the second group of material boxes 40 can repeat the above-mentioned transport process of the first group of material boxes 40 to move to the transfer section 330.

[0242] When the first group of material boxes 40 moves toward the transfer waiting area 52, the transfer section 330 switches to the third state. The second stopper 332 is opened, and the third stopper 333 is closed. The second stopper 332 blocks the first group of material boxes 40 from entering the second lifting section 340, and the first group of material boxes 40 stops at the transfer waiting area 52.

[0243] After the first group of material boxes 40 enters the transfer waiting area 52, the transfer section 330 switches to the fourth state. The third stopper 333 is opened to block the second group of material boxes 40 behind the first group of material boxes 40, achieving automatic sorting. At this time, the second tray of the second lifting section 340 is raised.

[0244] When the second group of sensors in the second lifting section 340 detects that the second tray is raised to the second position, the second tray stops rising, and the transfer section 330 switches to the fifth state. The second stopper 332 is closed, and the second rollers on the transfer slide 331 operate to move the first group of material boxes 40 in the transfer waiting area 52 into the second tray.

[0245] After the second group of sensors detects that the first group of material boxes 40 enters the second tray, the second tray descends toward the first position. In this process, the transfer section 330 can switch to the third state. The second stopper 332 is opened, and the third stopper 333 is closed, so that the second group of material boxes 40 enters the transfer waiting area 52.

[0246] When the first group of sensors in the second lifting section 340 detects that the second tray is lowered to the first position, the second tray stops descending. The drive rollers in the second tray operate to move the first group of material boxes 40 from the second tray to the discharge section 350. After the first group of material boxes 40 is transferred to the discharge section 350, the subsequent second group of material boxes 40 can repeat the above-mentioned transport process of the first group of material boxes 40 to move to the discharge section 350.

[0247] When the first set of material boxes 40 moves from the second tray to the discharge section 350, the first sub-roller 3514 in the discharge chute 351 drives the first set of material boxes 40 towards the discharge waiting area 53. When the third sensor detects that the first material box 40 in the first set of material boxes 40 has passed the third sensor, the box-separating stop 352 opens to block the second material box 40 in the first set of material boxes 40, allowing the first material box 40 to enter the discharge waiting area 53 (such as the first sub-waiting area 531). When the fourth sensor detects that the first material box 40 has entered the discharge waiting area 53, the box-separating stop 352 closes, allowing the second material box 40 in the first set of material boxes 40 to enter the discharge waiting area 53. At this time, the box-separating blocker 353 located in the discharge waiting area 53 switches from the first blocking state to the second blocking state to block the second material box 40, so that the first material box 40 and the second material box 40 in the first set of material boxes 40 are separated by a preset distance.

[0248] When the fifth sensor detects that the second material box 40 in the first group of material boxes 40 has entered the discharge waiting area 53 (such as the second sub-waiting area 532), the steering conveyor 354 switches from the first conveying state to the second conveying state, the lifting seat 3544 rises, and multiple conveying components 3547 lift the first group of material boxes 40. Finally, the conveying drive component 3543 drives the belt 35472 to rotate, so that the two material boxes 40 of the first group of material boxes 40 enter the two assembly slides respectively for the assembly of the left and right doors.

[0249] In some embodiments, such as Figure 17 As shown, production line 1 also includes a controller 70, a first sub-controller 81, a second sub-controller 82, and multiple third sub-controllers 83. The controller 70, the first sub-controller 81, the second sub-controller 82, and the third sub-controller 83 can be programmable controllers (PLCs) or PLC control cabinets.

[0250] The controller 70 is a core control component and is configured to perform overall control of production line 1. For example, the controller 70 can send a control signal to the input section 310 to start the input section 310.

[0251] The controller 70 may be equipped with alarm indicator lights and buttons. Single-action operation can be performed by pressing the button. Here, "single-action operation" means that by continuously pressing and holding a button or switch, the equipment or actuator (such as a cylinder or motor) will continue to operate, and the operation will stop immediately when the button or switch is released.

[0252] The first sub-controller 81 is communicatively connected with the controller 70 and configured to receive control signals from the controller 70 to provide power (e.g., electricity) to at least one transport section (e.g., the input section 310, the first lifting section 320, the transfer section 330, the second lifting section 340, and the output section 350) in the production line 1.

[0253] The second sub-controller 82 is communicatively connected with the controller 70 and configured to receive control signals from the controller 70 to control the operation of at least one transport section in the production line 1. For example, the second sub-controller 82 can control the start and stop of a specific component (e.g., the first stopper 312, the second stopper 332, the third stopper 333, the bin stopper 352, or the fourth stopper 357) in the transport section.

[0254] The third sub-controller 83 is communicatively connected with the controller 70 or the second sub-controller 82 and configured to receive control signals from the controller 70 to control the operation of at least one transport section in the production line 1. Moreover, the third sub-controller 83 is further away from the controller 70 than the second sub-controller 82. For example, the third sub-controller 83 can control the start and stop of a specific component (e.g., the first stopper 312, the second stopper 332, the third stopper 333, the bin stopper 352, or the fourth stopper 357) in the transport section.

[0255] Since the third sub-controller 83 is further away from the controller 70 than the second sub-controller 82, the third sub-controller 83 can be referred to as a remote controller, and the second sub-controller 82 can be referred to as a near-end controller.

[0256] In some embodiments, as shown in FIG. 1, the controller 70 and the second sub-controller 82 can include remote I / O modules and be communicatively connected with the corresponding sub-controllers through the remote I / O modules. Figure 17

[0257] For example, the controller 70 is communicatively connected with the first sub-controller 81, the second sub-controller 82, and at least one third sub-controller 83 of the plurality of third sub-controllers 83 through the remote I / O modules. The second sub-controller 82 can be communicatively connected with other third sub-controllers 83 of the plurality of third sub-controllers 83 through the remote I / O modules to transmit control signals from the controller 70 to the third sub-controllers 83 that are further away from the controller 70, thereby improving the stability and reliability of signal transmission.

[0258] In some embodiments of the present application, since the distance between the first lifting section 320 and the second lifting section 340 is too large, control signals and data can be transmitted through the remote I / O modules. In this way, the controller 70 and the plurality of sub-controllers can remotely receive control signals and data, thereby improving the reliability and stability of the operation of the production line 1. ​

[0259] It should be noted that the production line 1 can further comprise a safety relay, which can be used in cooperation with at least one of the controller 70, the first sub-controller 81, the second sub-controller 82, and the plurality of third sub-controllers 83, so as to improve the reliability of the production line 1.

[0260] In some embodiments of the present application, the production line 1 can realize automatic entering, automatic carrying, automatic boxing, automatic carrying out, automatic entering into the left and right door assembly lines of the material box 40, reduce the transfer time of the material box 40, reduce the input of personnel and tools during the transportation of the material box 40, improve the production efficiency, and greatly improve the reliability, universality and automation of the production line 1.

[0261] In addition, by arranging a plurality of driving rollers at a plurality of transportation sections of the production line 1, the impact force of the material box 40 on the related stoppers or blockers can be reduced, the equipment can be prevented from being damaged, and the reliability and service life of the production line 1 and the material box 40 can be improved.

[0262] In order to facilitate the blocking or boxing of the material box 40 by each stopper in the present application, in some embodiments, as shown in FIGS. Figure 18 and Figure 19 The material box 40 comprises a box body 401 and a base 402. The box body 401 is arranged on the base 402. The base 402 is rectangular and is provided with a plurality of recesses 403 arranged at four sides of the base 402.

[0263] For example, the recess 403 can be a groove, which is recessed from one side of the base 402 to the inside of the base 402 in the first direction X or the second direction Y.

[0264] In this way, by arranging corresponding recesses 403 at the bottom of the material box 40, the first stopper 312, the second stopper 332, the third stopper 333, the boxing stopper 352, and the fourth stopper 357 in the carrying device 30 can be facilitated to block or box the material box 40, and the stability and reliability of the production line 1 can be improved.

[0265] In some embodiments, the box body 401 and the base 402 can be an integral piece to improve the strength of the material box 40. Alternatively, the box body 401 and the base 402 can be separate pieces to facilitate the installation and replacement of the base 402.

[0266] It can be understood that the production line 1 for the door in some embodiments of the present application can also be applied to the production of other components in the vehicle, as long as the corresponding sequential line 10 and the assembly line 20 are replaced. The door production line in some embodiments of the present application can be flexibly adapted to changes in later vehicle models and changes in production lines according to the actual production line, and has strong universality.

[0267] Also, the production line 1 in some embodiments of the present application can also simultaneously input three, four, or more side-by-side material boxes 40, as long as the corresponding components for blocking and boxing are added, and the present application is not limited thereto.

[0268] In the description of the embodiments of the present application, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0269] The above merely describes specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
