Description

Technical Field

[0002] Currently, automated handling equipment such as automatic guided vehicles (AGVs) have been widely used in warehousing, logistics and other fields to realize the automated transportation of goods.

[0003] An AGV consists of a chassis and various parts mounted on its top and bottom surfaces. During the installation of parts onto the chassis, the chassis's position needs to be adjusted (for example, the top surface of the chassis needs to be flipped) to facilitate the worker's installation operation.

[0004] In actual use cases, adjusting the chassis's posture often requires the cooperation of multiple people, making the assembly of automated guided vehicles (AGVs) significantly labor-intensive. Furthermore, it's often difficult for multiple workers to achieve a high degree of coordination and unity. If one person fails to perform the operation properly, it can pose a safety hazard to all the other workers involved in the assembly process. Furthermore, due to the limited order in which parts must be installed, the chassis's posture needs to be adjusted multiple times during the AGV assembly process, resulting in low assembly efficiency and significant safety risks.

[0076] To make the purpose, technical solutions, and advantages of this specification more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this specification and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0077] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0078] like Figures 1 to 15 As shown, this specification provides a partial structural schematic diagram of an automated guided vehicle assembly tool. The automated guided vehicle assembly tool may include: a base frame 1 and a bracket 2. The base frame 1 is used to at least support the bracket 2 and the chassis, parts, etc. of the automated guided vehicle placed on the bracket 2. The bracket 2 is used to at least place the chassis and provide an assembly space for the user to assemble the automated guided vehicle. The bracket 2 is mounted on the base frame 1, and the specific relative position of the bracket 2 and the base frame 1 can be customized according to the user's needs. For example, the bracket 2 can be mounted on the top of the base frame 1.

[0079] The two sides of the surface formed by the bracket 2 correspond to the preset first assembly positions (such as Figure 1 The bracket 2 can be turned relative to the base frame 1 to adjust the orientation of both sides of the bracket 2, so that the bracket 2 can be adjusted from the first assembly position to the second assembly position, and can be adjusted from the second assembly position to the first assembly position. Figure 1 For example, the assembly position may be parallel to the vertical direction; for another example, the angle between the planes formed by the first assembly position and the second assembly position is an acute angle.

[0080] Alternatively, as Figures 1 to 3d,as well as Figure 6 As shown, the bracket 2 can be a rectangular frame structure to support the chassis in the circumferential direction of the chassis. Furthermore, in order to strengthen the lifting capacity of the chassis, the automatic guided vehicle assembly tooling also includes a support beam 6 connected to the bracket 2 and extending within the plane formed by the bracket 2 (for example, within the plane formed by the bracket 2, extending toward the center of the bracket 2). The size of the support beam 6 in the direction of its extension is smaller than the size of the bracket 2 in this direction, so that the support beam 6 provides support for the chassis without occupying too much space of the bracket 2. The number of support beams 6 can be multiple, and multiple support beams 6 can be arranged along the circumference of the bracket 2.

[0081] Optionally, the chassis may have Figure 4 The structure shown.

[0082] like Figure 1 As shown, in the scenario where the bracket 2 can be set at the top of the base frame 1, the axial direction of the bracket 2 can be parallel to the horizontal plane when it is turned over. Then, when the bracket 2 is in the first assembly position, one side of the bracket 2 faces the top of the AGV assembly tool, so that one side of the chassis located on the bracket 2 also faces the top of the AGV assembly tool, which facilitates workers to perform assembly operations on that side of the chassis; when the bracket 2 is in the second assembly position, the other side of the bracket 2 faces the top of the AGV assembly tool, so that the other side of the chassis located on the bracket 2 also faces the top of the AGV assembly tool, which facilitates workers to perform assembly operations on the other side of the chassis.

[0083] Furthermore, the AGV assembly tool in this specification further includes a flip connection mechanism, which is at least used to achieve a flippable connection between the bracket 2 and the base frame 1 .

[0084] like Figures 1 to 3d ,as well as Figure 5a and Figure 5b As shown, the flip connection mechanism in this specification includes: a shaft 31 and a shaft seat provided on the base frame 1. One end of the shaft 31 is provided in the seat hole 326 of the shaft seat, and the other end of the shaft 31 is connected to the bracket 2. The end of the shaft 31 that cooperates with the shaft seat can be embedded in the seat hole 326 in the shape of a groove 521; or it can pass through the seat hole 326 in the shape of a through hole. This specification does not impose specific restrictions on the cooperation method between the shaft 31 and the shaft seat. The following is an example of the end of the shaft 31 that cooperates with the shaft seat and passes through the seat hole 326 in the shape of a through hole. In addition, the connection between the other end of the shaft 31 and the bracket 2 can be a direct connection or an indirect connection achieved through other components.

[0085] In addition, the automatic guided vehicle assembly tool in this specification also includes a flip locking mechanism, which is at least used to lock the relative position between the bracket 2 and the base frame 1.

[0086] For example, Figures 2 to 3d ,as well as Figure 6 and Figure 7 As shown, the flip locking mechanism includes: a lock pin 41 (as shown Figure 13 As shown in the figure, and the locking fitting 42 fixedly connected to the shaft 31, when the bracket 2 is flipped over, the locking fitting 42, the shaft 31 and the bracket 2 are flipped over together. The locking fitting 42 and the shaft seat are respectively provided with matching lock holes. The "matching" method can be that the lock hole 421 of the locking fitting 42 and the lock hole 324 of the shaft seat are axially colinear. When the bracket 2 is flipped over to a preset assembly position relative to the base frame 1, the lock hole 421 of the locking fitting 42 and the lock hole 324 of the shaft seat are opposite to each other along the axial direction of the lock holes, so that the locking pin 41 can pass through the lock holes 324 respectively provided on the locking fitting 42 and the shaft seat.

[0087] like Figures 2 to 3d As shown, the locking fitting 42 can be connected to the one end of the shaft 31 on the side of the shaft seat away from the bracket 2. Figure 7 As shown, at least a portion of the locking member 42 is plate-shaped or rod-shaped, and the size or axial dimension of one side of the locking member 42 is larger than the radial dimension of the seat hole 326, so that the locking member 42 cannot pass through the seat hole 326. Therefore, the locking member 42 can not only be used to lock the relative position between the bracket 2 and the base frame 1, but also be used to limit the position between the bracket 2 and the base frame 1 in the axial direction of the shaft 31.

[0088] It should be noted that the aforementioned connection method and relative position relationship between the locking fitting 42 and the shaft 31 are only examples. In an optional embodiment of the present invention, the locking fitting 42 can also be connected to the shaft 31 between the two ends of the shaft 31, so that the locking fitting 42 is located between the shaft seat and the bracket 2.

[0089] Alternatively, as Figures 2 to 3d As shown, the axial directions of the locking hole 421 of the locking fitting 42 and the axial directions of the locking hole 324 of the shaft seat are both parallel to the axial direction of the shaft 31. When the relative position between the bracket 2 and the base frame 1 is locked, the locking pin 41 can be inserted into the locking hole 421 of the locking fitting 42 and the locking hole 324 of the shaft seat along the axial direction of the shaft.

[0090] And / or, the locking fitting may be an annular structure that, in the radial direction of the seat hole, shields at least a portion of the shaft seat along the outer circumference of the shaft seat. The axial directions of the locking hole of the shaft seat and the locking fitting are both arranged along the radial direction of the seat hole. The bracket is then flipped. When the bracket is flipped relative to the base frame to a predetermined assembly position, the locking holes provided in the locking fitting and the shaft seat are axially opposed to each other, allowing the locking pin to penetrate the locking holes provided in the locking fitting and the shaft seat.

[0091] As can be seen, the axle seat of the automated guided vehicle assembly tooling described in this specification is not only used to establish a reversible connection between the bracket 2 and the base frame 1; it is also used to achieve locking and positioning between the bracket 2 and the base frame 1 when the bracket 2 is flipped to the preset assembly position. This requires that the axle seat described in this specification not only meet certain functional requirements but also have corresponding flexibility.

[0092] To achieve this goal, Figure 5a and Figure 5b As shown, in an optional embodiment of the present specification, the shaft seat includes a first shaft seat component 321 and a second shaft seat component 322 that are arranged to be snap-fitted along the radial direction of the shaft 31 .

[0093] The first shaft seat 321 and the second shaft seat 322 are respectively provided with notches at positions opposite to each other, that is, Figure 5a As shown in FIG, the notch 321a of the first shaft seat 321 and the notch 322a of the second shaft seat 322 are of the same shape and size. Optionally, the notch 321a of the first shaft seat 321 and the notch 322a of the second shaft seat 322 have the same shape and size and are both semicircular. After the first shaft seat 321 and the second shaft seat 322 are fastened together, the notch 321a of the first shaft seat 321 and the notch 322a of the second shaft seat 322 together form the seat hole 326 of the shaft seat.

[0094] Then, after the locking fitting 42 is connected to the shaft 31, the shaft 31 is placed in the notch 321a of the first shaft seat 321 or the notch 322a of the second shaft seat 322, and then the locking fitting 42 is connected to the shaft 31. Figure 5a In the direction C shown, the first shaft seat member 321 and the second shaft seat member 322 are buckled together along the radial direction of the seat hole 326. When the shaft 31 and the shaft seat are assembled in this specification, there will be no instability caused by the locking fitting 42 connected as one body with the shaft 31.

[0095] Optionally, the first shaft seat component 321 includes a first shaft seat component connecting hole 321b extending axially in the direction of the fastening, and the second shaft seat component 322 includes a second shaft seat component connecting hole 322b extending axially in the direction of the fastening. The axial direction of the first shaft seat component connecting hole 321b and the axial direction of the second shaft seat component connecting hole 322b are collinear. After the first shaft seat component 321 and the second shaft seat component 322 are fastened together, the shaft seat connector 323 can be inserted into the first shaft seat component connecting hole 321b and the second shaft seat component connecting hole 322b to connect the first shaft seat component 321 and the second shaft seat component 322 together. Optionally, the shaft seat connector 323 is a threaded pin, and threads that mate with the threaded pin are provided circumferentially of the first shaft seat component connecting hole 321b and the second shaft seat component connecting hole 322b.

[0096] Furthermore, in order to improve the processing accuracy and reduce the processing difficulty, the lock hole on the shaft seat can also have a similar structure to the seat hole 326. Specifically, Figure 5a and Figure 5b As shown, the first and second axle base members 321, 322 are each provided with a gap at a position opposite to each other, so that when the first and second axle base members 321, 322 are engaged, the gaps provided on the first and second axle base members 321, 322 together form the axle seat's locking hole 324. If the locking pin 41 is found to be stuck in the locking hole during use, the locking hole 324 of the axle seat can be disassembled by removing the first and / or second axle base members 321, 322, to facilitate removal of the locking pin 41.

[0097] This specification does not restrict the relative positions of the first axle seat component 321 and the second axle seat component 322 with respect to the base frame 1. During assembly of the axle seat, if the first axle seat component 321 and the second axle seat component 322 are engaged in a direction parallel to the plane of the assembly position (e.g., horizontally), both the first axle seat component 321 and the second axle seat component 322 can be connected to the base frame 1. After the axle seat is assembled, the base frame 1 can provide positioning for the connection between the first axle seat component 321 and the second axle seat component 322 in the engaging direction.

[0098] In addition, if Figures 2 to 3d As shown, when assembling the axle seat, if the first axle seat member 321 and the second axle seat member 322 are buckled in a direction perpendicular to the plane where the assembly position is located (for example, a vertical direction), the first axle seat member 321 can be connected to the base frame 1, and the second axle seat member 322 is positioned with the base frame 1 through the first axle seat member 321. Figure 5a and Figure 5bAs shown, the first axle seat member 321 includes a first axle seat member positioning hole 321c, and the base frame 1 includes an axle seat positioning and mating hole 11 that mates with the first axle seat member positioning hole 321c. The axial direction of the first axle seat member positioning hole 321c is collinear with the axial direction of the first axle seat member positioning hole 321c, and the axial direction of the first axle seat member positioning hole 321c and the axial direction of the first axle seat member positioning hole 321c can be parallel to the vertical direction. After the first axle seat member 321 is placed at the corresponding position on the base frame 1, the first axle seat member 321 and the base frame 1 can be positioned by the axle seat positioning member 325 that passes through the first axle seat member positioning hole 321c and the axle seat positioning and mating hole 11.

[0099] For ease of description, the following description will be made by taking as an example the case where the first shaft seat member 321 and the second shaft seat member 322 are buckled together in a direction perpendicular to the plane where the assembly position is located.

[0100] The AGV assembly tooling of the aforementioned embodiment can be used to perform the chassis flipping operation when assembling an AGV. To further improve the safety and stability of the flipping operation and to provide a stable assembly working environment for workers after the AGV assembly tooling is adjusted to the assembly position, the chassis 1 of the AGV assembly tooling in this specification is provided on two opposite sides of the bracket 2, such as Figure 1 As shown, they are respectively connected to the bracket 2 in a flippable manner through the flip connection mechanism.

[0101] In order to prevent the chassis from sliding off the bracket 2 when the bracket 2 and the chassis placed on the bracket 2 are turned over, the automatic guided vehicle assembly tool in this specification also includes: a press 5 for fixing the chassis of the automatic guided vehicle on the bracket 2, such as Figures 8 to 12b shown.

[0102] The press 5 includes a support portion 51 and a connecting portion 52 that forms an angled structure with the support portion 51. The support portion 51 is detachably connected to the bracket 2. The end of the support portion 51, distal from the bracket 2, is connected to the connecting portion 52. The connecting portion 52 can extend parallel to the surface defined by the bracket 2. The space defined between the surface defined by the connecting portion 52 and the surface defined by the bracket 2 can accommodate at least a portion of the chassis of the automated guided vehicle.

[0103] In such Figure 1 In the first assembly position shown, the bracket 2 supports the chassis from the bottom side, and the connection portion 52 of the hold-down tool 5 engages with the chassis above the chassis edge. In the second assembly position, the bracket 2 holds the chassis in place from the top side, and the connection portion 52 of the hold-down tool 5 engages with the chassis below the chassis edge to support the chassis.

[0104] To enhance the ability of the hold-down tool 5 to retain the chassis in the thickness direction, this specification further designs the connection portion 52 of the hold-down tool 5. Specifically, the connection portion 52 comprises a first screw hole 522 extending in the normal direction of the surface defined by the bracket 2, and a first threaded pin 523 threadedly connected to the first screw hole 522. After the chassis is placed on the bracket 2, the relative position of the first threaded pin 523 and the first screw hole 522 can be adjusted in the normal direction to adjust the hold-down tool 5's ability to retain the chassis in that direction.

[0105] For example, the first screw hole 522 and the first threaded pin 523 are respectively provided with matching threads. The first threaded pin 523 is rotated to adjust the relative position of the first threaded pin 523 and the first screw hole 522 in the normal direction of the surface formed by the bracket 2 (which can be the axial direction of the first threaded pin 523).

[0106] Optionally, the first screw holes 522 and the first threaded pins 523 may be provided in corresponding groups.

[0107] Furthermore, to enhance the ability of the press 5 to position the chassis parallel to the plane defined by the bracket 2, this specification further designs the support portion 51 of the press 5. Specifically, the support portion 51 comprises a second screw hole 511 extending axially along the shaft 31 and a second threaded pin 512 threadedly connected to the second screw hole 511. After the chassis is placed on the bracket 2, the relative position of the second threaded pin 512 and the second screw hole 511 can be adjusted axially along the shaft 31 (which can be the axial direction of the second threaded pin 512) to adjust the press 5's ability to hold the chassis in the axial direction of the second threaded pin 512.

[0108] Optionally, there are multiple press tools 5, with at least two of the multiple press tools 5 being respectively disposed on two opposite sides of the bracket 2. Then, the relative positions of the second threaded pin 512 and the second screw hole 511 are adjusted to adjust the holding capacity of the press tools 5 disposed on the two opposite sides of the bracket 2 on the chassis.

[0109] In order to improve the stability of the connection between the connecting portion 52 and the chassis, a groove 521 and / or a protrusion for connecting with the chassis of the automatic guided vehicle is provided on the side of the connecting portion 52 facing the surface formed by the bracket 2. Figures 8 to 12b As shown, the following description will be made by taking the example of the connection portion 52 being clamped to the chassis through the groove 521 .

[0110] In actual use, a plurality of pressers 5 with different extending directions of the grooves 521 can be prepared in advance. The extending direction of the grooves 521 can be as follows: Figure 8The illustrated extension direction is along the side where the bracket 2 is connected to the pressing tool 5, and may also be at a certain angle to the extension direction of the side. When matching different models of chassis or different positions of the chassis, a pressing tool 5 that matches the position of the chassis can be selected.

[0111] Alternatively, the press can further include a mating portion that can be disposed on the chassis and engage with the groove of the connecting portion. The mating portion includes a clamping head disposed at one end and a rib disposed at the other end. The rib can then be engaged with the mating groove of the connecting portion, and the clamping head can then be clamped onto the chassis to achieve positioning of the press on the chassis.

[0112] Because the edge of the chassis is not smooth before assembly, and the thickness of each position of the chassis edge is not uniform, it is possible to prepare multiple presses 5 with support parts 51 of different sizes in advance. At the position where the chassis is thicker, a press 5 with a larger support part 51 (hereinafter referred to as the second press, such as Figures 8 to 9b ,as well as Figure 12a As shown, optionally, the size of the second press along the normal direction of the plane formed by the bracket 2 is larger than the size of the first press along the same direction). At the position where the thickness of the chassis is smaller, a press 5 with a smaller support portion 51 (hereinafter referred to as the first press, as shown) can be used. Figures 10 to 11c ,as well as Figure 12b shown).

[0113] In actual use, if the required press 5 is the first press, the space provided by the support portion 51 of the first press may not be sufficient to set the second screw hole 511 and the second threaded pin 512; or in order to avoid the second screw hole 511 and the second threaded pin 512 from affecting the use of the groove 521 of the connecting portion 52. In order to solve this problem, this specification provides a boss 58 protruding along the plane where the bracket 2 is located on one side of the support portion 51 extending radially along the shaft 31 for the first press. The second screw hole 511 and the second threaded pin 512 can be set on the boss 58, as shown in FIG. Figures 8 to 9b ,as well as Figure 12a shown.

[0114] In actual use, to match the chassis structure, the bracket 2 is often configured with a contour that matches the chassis at the point where it contacts the chassis. This increases the risk of an unstable connection between the press 5 and the bracket 2. Therefore, the press 5 described herein may further include a spacer 53 disposed between the support portion 51 and the bracket 2. The spacer 53 is an angled or arc-shaped structure that matches at least a portion of the bracket 2's contour.

[0115] like Figures 7 to 12bAs shown, to achieve the connection between the support portion 51 and the cushion block 53, the cushion block 53 in this specification is provided with a cushion block connection hole 531, and the support portion 51 is provided with a support portion connection hole 56 that cooperates with the cushion block connection hole 531. After adjusting the support portion 51 and the cushion block 53 so that the cushion block connection hole 531 and the support portion connection hole 56 are axially aligned, the presser connector 54 can be inserted into the cushion block connection hole 531 and the support portion connection hole 56 to achieve the connection between the support portion 51 and the cushion block 53. Optionally, the presser connector 54 is threadedly connected to the cushion block connection hole 531 and the support portion connection hole 56, respectively.

[0116] There may be multiple groups of presser connectors 54 , pad connection holes 531 and support portion connection holes 56 .

[0117] like Figures 7 to 12b As shown, in order to achieve the positioning between the press 5 and the bracket 2, the pad 53 in this specification is further provided with a pad positioning hole 532, the support portion 51 is further provided with a press positioning hole 57, and the bracket 2 is provided with an auxiliary positioning hole (not shown in the figure). After adjusting the support portion 51 and the pad 53 until the pad positioning hole 532, the press positioning hole 57 and the auxiliary positioning hole are axially aligned, the press positioning member 55 (as shown in FIG. Figure 14 As shown in the figure, the pressing tool 5 is inserted into the pad block positioning hole 532, the pressing tool positioning hole 57 and the auxiliary positioning hole to achieve positioning between the pressing tool 5 and the bracket 2.

[0118] When installing components such as the hold-down tool 5 on the bracket 2, the position of the hold-down tool 5 on the bracket 2 is typically determined based on the actual connection point between the hold-down tool 5 and the chassis. This results in a certain degree of instability in the relative position of the bracket 2 and chassis 1 before the two are locked. Ignoring the actual installation position of the hold-down tool 5 on the bracket 2 may exacerbate this instability, potentially creating a safety hazard due to the shaking of the bracket 2 before the worker locks it.

[0119] To avoid this phenomenon, the first pressing tool in this specification has a pad 53 (such as Figure 7 The pad connection hole 531 and the pad positioning hole 532 on the pad 53 are both arranged on the left or right side of the center line of the pad 53. The center line is: in the plane formed by the bracket 2, the center line of the pad 53 perpendicular to the extension direction of the side of the bracket 2 and the pad 53. The support part 51 and the connection part 52 of the first press are both biased to the left or right side of the pad 53 and connected to the pad 53. That is, the center of gravity of the first press is biased to the left or right side of the first press. Then, the point of action of the gravity of the first press on the bracket 2 can be adjusted without affecting the connection position of the first press and the chassis.

[0120] Furthermore, the second pressing tool in this specification has a pad 53 (such as Figure 7 The pad connection holes 531 and pad positioning holes 532 on the pad 53 (shown in area G) are evenly distributed on the pad 53 relative to the centerline of the pad 53. The centerline is the centerline of the pad 53, perpendicular to the extending direction of the side of the bracket 2 that mates with the pad 53, within the plane formed by the bracket 2. The connection position of the connecting portion 52 of the second hold-down tool to the chassis is farther from the bracket 2, primarily to improve the stability of the second hold-down tool in limiting the chassis.

[0121] The parts required to be assembled on both sides of the chassis of an automated guided vehicle are often different. According to the requirements of the assembly environment, providing each side of the chassis with an appropriate assembly height when assembling the parts on both sides of the chassis will help improve the assembly efficiency of the automated guided vehicle.

[0122] Therefore, the flip connection mechanism of the automatic guided vehicle assembly tool in this specification further includes: a height adjustment member 33.

[0123] like Figures 1 to 3a ,as well as Figure 6 and Figure 7 As shown, the shaft 31 and the bracket 2 are respectively connected to the two ends of the height adjustment member 33. The line between the two ends of the height adjustment member 33 extends along the radial direction of the shaft 31. Optionally, the difference between the height of the bracket 2 from the ground when it is in the first assembly position and the height of the bracket 2 from the ground when it is in the second assembly position is twice the length of the line between the two ends of the height adjustment member 33. If the first assembly position and the second assembly position have different heights relative to the ground (the height of the first assembly position can be greater than the height of the second assembly position, or the height of the second assembly position can be greater than the height of the first assembly position), the different assembly height requirements on both sides of the chassis can be met.

[0124] In order to facilitate the workers to assemble the automatic guided vehicle, the automatic guided vehicle assembly tool further includes: an auxiliary frame 7 arranged on the base frame 1, such as Figure 4 The auxiliary frame 7 includes a plurality of auxiliary holes 71 and / or auxiliary slots for placing and / or hanging tools and / or parts required for assembling the automatic guided vehicle.

[0125] In addition, the automatic guided vehicle assembly tool also includes: a caster 8 provided at the bottom end of the chassis 1, such as Figure 15 As shown. This allows workers to adjust the automated guided vehicle assembly tooling between different workstations when assembling the automated guided vehicle. Optionally, the caster 8 includes a wheel body 82 and a brake member 81, and the brake member 81 can be used to limit the rotation of the wheel body 82.

[0126] Based on the same idea, the embodiment of this specification also provides a corresponding automatic guided vehicle assembly process, some steps of the automatic guided vehicle assembly process are as follows: Figure 16 shown.

[0127] Figure 16 The automatic guided vehicle assembly process provided in the embodiments of this specification may specifically include the following steps:

[0128] S160: Turn over the bracket 2 to a preset first assembly position.

[0129] The first assembly position can be an assembly position closer to the ground. After the chassis is placed on the bracket 2, the sum of the distance from the first assembly position to the ground and the thickness of the chassis can provide workers with a suitable installation height on the upward side of the chassis.

[0130] After the bracket 2 is flipped to the preset first assembly position, the axial direction of the locking hole 421 of the locking fitting 42 and the axial direction of the locking hole 324 of the shaft seat are collinear.

[0131] S162: The locking pin 41 is passed through the locking holes 324 respectively provided on the locking fitting 42 and the shaft seat to lock the relative positions of the bracket 2 and the base frame 1.

[0132] In this step, the locking pin 41 is inserted into the locking hole 421 of the locking fitting 42 and the locking hole 324 of the axle seat along the axial direction of the locking hole. While locking the relative position between the locking fitting 42 and the axle seat, the locking between the bracket 2 connected to the locking fitting 42 and the base frame 1 connected to the axle seat is achieved, so that the bracket 2 remains in the first assembly position.

[0133] S164: Place the chassis of the automatic guided vehicle on the bracket 2, and assemble at least some of the parts on the chassis.

[0134] In this step, the chassis is placed on the bracket 2 so that the chassis is in the first assembly position, so that a worker can assemble at least part of the parts to the chassis at the first assembly position.

[0135] Because the flip locking mechanism has locked the bracket 2 to the chassis 1, the bracket 2 has sufficient stability in the first assembly position to meet assembly requirements. To further improve the positioning capability of the AGV assembly tool for the chassis, after the chassis is placed on the bracket 2, a press 5 can be installed on the bracket 2 to position the chassis using the space defined between the surface formed by the connecting portion 52 of the press 5 and the surface formed by the bracket 2.

[0136] S166: Remove the locking pin 41 placed in the locking hole, and flip the bracket 2 to a preset second assembly position.

[0137] After at least some of the components are assembled onto the chassis, the other side of the chassis can be assembled. In this step, the locking pin 41, located in the locking hole, is first removed to unlock the lock between the bracket 2 and the chassis 1. The bracket 2 is then flipped over to the second assembly position.

[0138] S168: The locking pin 41 is again passed through the locking holes respectively provided on the locking fitting 42 and the axle seat to lock the relative positions of the bracket 2 and the base frame 1, and at least part of the remaining parts are assembled to the chassis.

[0139] In this step, the locking pin 41 is inserted into the locking hole 421 of the locking fitting 42 and the locking hole 324 of the shaft seat along the axial direction of the locking hole. This locks the relative position between the locking fitting 42 and the shaft seat, and simultaneously locks the bracket 2 connected to the locking fitting 42 and the base frame 1 connected to the shaft seat, so that the bracket 2 remains in the second assembly position. The worker can then assemble at least some of the remaining parts onto the upward side of the chassis.

[0140] Afterwards, if there are still parts that need to be installed on the chassis under the condition that the chassis is in the first assembly position, the locking pin 41 placed in the lock hole can be removed again, and the bracket 2 can be flipped to the preset first assembly position. After locking the relative position of the bracket 2 and the chassis 1 by the flipping locking mechanism, continue to assemble parts on the chassis in the first assembly position.

[0141] As can be seen, thanks to the automated guided vehicle assembly tool and automated guided vehicle assembly method provided in this specification, when assembling an automated guided vehicle, one need only place the chassis of the automated guided vehicle on bracket 2 of the automated guided vehicle assembly tool. By flipping bracket 2 mounted on the chassis 1, the chassis can be adjusted between various preset assembly positions. This reduces the manpower and material resources consumed in adjusting the chassis's position, improves operational efficiency, and mitigates operational safety hazards.

[0142] The order processing process in a warehouse typically involves two steps: picking and sorting. Picking primarily involves using automated guided vehicles (AGVs) to remove the goods involved in multiple orders from various storage areas within the warehouse and transport them to designated sorting locations. Sorting, on the other hand, involves sorting the goods required for each order from the goods carried by the AGVs and transporting them to the corresponding containers. The AGV assembly tooling and AGV assembly method described in this manual refer to the tooling required for assembling AGVs.

[0143] During the sorting process, the goods carried by the automated guided vehicle are usually picked up manually and placed in the containers corresponding to each order. This is not only inefficient, but also prone to workers placing goods in containers corresponding to other orders. When an automated guided vehicle assembled using the automated guided vehicle assembly tooling and the automated guided vehicle assembly method described in this specification is used in the order processing process of a warehouse, it is only necessary to place the goods to be transported on the handling equipment. The control center can determine the target assembly container to which the goods carried by the handling equipment need to be delivered based on the identification information of the handling equipment obtained, the identification information of the goods carried by the handling equipment, and the stored multiple corresponding relationships. Then, by sending a handling instruction to the handling equipment, the handling equipment is instructed to go to the location of the target assembly container and deliver the carried goods to the target assembly container. This not only effectively ensures that each goods are accurately delivered to the corresponding assembly container, but also effectively improves the sorting efficiency of goods sorting.

[0144] In a warehouse environment, automated guided vehicles can perform sorting and / or picking operations for goods under the control of a goods picking system.

[0145] Specifically, the cargo picking system includes: an automatic guided vehicle, a remotely located controller, an inventory area, and a picking workstation. The inventory area contains multiple shelves or inventory racks similar to shelves, and various inventory goods are placed on the inventory racks, or inventory containers are placed on the inventory racks, and various inventory goods are contained in the inventory containers. Multiple inventory racks form a group, and different groups are arranged in an array.

[0146] A staff member operates the controller through an operating console. The controller communicates wirelessly with the self-propelled mobile robot, and the automated guided vehicle performs the handling task under the control of the controller. For example, based on inventory information, the controller selects an inventory rack or an inventory container on the inventory rack for an order. The inventory rack or the inventory container contains the ordered goods for the order. In addition, the controller selects a picking workstation and an automated guided vehicle for the order and plans a navigation path for the automated guided vehicle from the original position to the picking workstation. The automated guided vehicle travels along the empty space in the inventory rack array (part of the automated guided vehicle passage) according to the navigation path. To facilitate the planning of the navigation path for the automated guided vehicle, the working area of ​​the automated guided vehicle (which includes at least the inventory area and the area where the picking workstation is located) can be pre-divided into several sub-areas (i.e., cells). The automated guided vehicle moves in each sub-area to form a motion trajectory.

[0147] The compartments on the inventory rack can be loaded with inventory containers such as bins or pallets. The bins can hold individually disassembled inventory items (e.g., cans of cola), and the pallets can hold entire pallets of inventory items (e.g., boxes of cola). The automated guided vehicle can transport the entire inventory rack to a picking station for goods picking operations, or it can grab an inventory container (e.g., a bin or pallet) on the inventory rack and transport the inventory container to a picking station for goods picking operations. Of course, the inventory rack can also use other suitable loading methods to load bins, pallets, or other types of inventory containers, all of which are within the scope of protection of this application.

[0148] Taking the example of an automated guided vehicle transporting a shelf, the automated guided vehicle may include a drive mechanism, through which the automated guided vehicle can move within the workspace. The automated guided vehicle may also include a lifting mechanism for transporting the shelf. The automated guided vehicle can move to the bottom of the shelf, use the lifting mechanism to lift the shelf, and transport it to the assigned picking workstation. When the lifting mechanism is raised, the entire shelf is lifted from the ground so that the automated guided vehicle can transport the shelf. When the lifting mechanism is lowered, the shelf is placed on the ground. The target recognition component (for example, a camera) on the automated guided vehicle can effectively identify the shelf when the automated guided vehicle lifts the shelf.

[0149] In addition, if the AGV is based on visual marker navigation, it also includes a navigation recognition component for identifying markers laid on the ground (such as QR codes). In addition to visual marker navigation, the AGV can also use other navigation methods, such as inertial navigation and SLAM (Simultaneous Localization And Mapping) navigation. It can also combine two or more navigation methods simultaneously, such as QR code navigation and inertial navigation, SLAM navigation and QR code navigation, etc. Of course, the AGV also includes a control module that controls the entire AGV to achieve functions such as movement and navigation.

[0150] In one example, the automatic guided vehicle includes at least two cameras, one facing upward and one facing downward, which can capture information of a QR code mark (or other ground mark) based on the downward camera and move forward, and can move to the bottom of the shelf prompted by the controller according to the navigation path determined by the controller. For example, goods can be stored directly on the shelf, and of course the goods can also be stored in inventory containers, such as bins or pallets. In a specific embodiment, the shelf includes a plurality of compartments stacked in a vertical direction, and each compartment can accommodate multiple goods. A QR code mark is provided in the center of the bottom of the shelf. When the automatic guided vehicle drives under the shelf, the QR code mark is correctly captured by the upward camera to ensure that the automatic guided vehicle is located directly under the shelf, thereby ensuring that the automatic guided vehicle can smoothly lift and carry the shelf, and the shelf includes one or more support parts. In addition, in a specific embodiment, the goods can also be hung from hooks or rods inside or on the shelf. The goods on the shelf can be placed on the inside or outside surface of the shelf in any appropriate manner.

[0151] After the automated guided vehicle transports the shelf to the picking workstation, workers performing picking operations or automated equipment (such as robotic arms) pick the goods from the shelf and place them in turnover boxes on the seed wall to wait for further operations, such as packaging.

[0152] The above process is the picking stage of the order processing flow in the warehouse. After the picking stage is completed, the packaged parcels need to be sorted and finally shipped by express delivery.

[0153] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.

[0154] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
