In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides an assembly fixture suitable for assembling vehicles, especially motorcycles. Furthermore, the assembly fixture of this embodiment, through its innovative structural design, enables automatic unlocking and clamping of the wheels, simplifies the operation process, and improves production efficiency.

[0032] In related technologies, vehicles, especially straddle-type vehicles, generally include various types of motorcycles, and their unloaded weight is generally heavy. Some heavy-duty models of straddle-type vehicles have an unloaded weight exceeding 400KG, which places higher demands on the assembly process. However, the traditional frame-lifting and conveying method used in straddle-type vehicle production lines is unsuitable for the assembly and assembly of heavy-duty straddle-type vehicles, potentially causing damage to vehicle structural components. While some straddle-type vehicle production lines now use wheel clamps, they typically suffer from cumbersome unlocking and locking mechanisms, hindering production efficiency.

[0033] In view of this, in order to overcome the shortcomings of related technologies, the assembly tooling in this embodiment combines... Figures 1 to 17 As shown, the overall design includes a base 100. A clamping assembly 200 includes two clamping members 201 slidably disposed on the base 100 along a first direction, the two clamping members 201 forming a clamping space for clamping the wheel. Two first driving units 300 are provided, each corresponding to one of the two clamping members 201, and the driving end of each first driving unit 300 is extendable and retractable along the first direction.

[0034] The first drive unit 300 consists of two units, each corresponding to one of the two clamping members 201. The drive end of each first drive unit 300 is extendable and retractable in a first direction. A locking unit 400 is located between each clamping member 201 and the base 100 to lock the clamping member 201 onto the base 100, forming a clamping space. The locking unit 400 can be driven by the drive end of the first drive unit 300 to release the locking of the clamping member 201. A traction unit 500 is located between the clamping member 201 and the drive end. The first drive unit 300 can pull the unlocked clamping member 201 to slide through the traction unit 500, thereby releasing the clamping of the wheel.

[0035] Therefore, by providing a clamping assembly 200 for forming a clamping space for holding the wheel on the base 100, and a first drive unit 300 corresponding to the clamping assembly 200, and further including a locking part 400 capable of locking the clamping member 201 on the base 100, and a traction part 500 provided between the clamping member 201 and the drive end, the first drive unit 300 can pull the unlocked clamping member 201 by the traction part 500 to release the clamping of the wheel. With this configuration, the assembly tool can automatically unlock and clamp the wheel, thereby simplifying the operation process and improving production efficiency.

[0036] Based on the above overview, specifically, refer to Figures 5 to 6 The clamping assembly 200 further includes a first guide rail 101 disposed on the base 100 and extending along a first direction. Multiple first guide rails 101 are spaced apart along a third direction. Preferably, there are two first guide rails 101. A base plate 102, which is elongated, extends along a third direction, and is slidable along the first direction, is disposed on the first guide rail 101. A mounting plate 103 is disposed on the base plate 102 for mounting the clamping member 201. The mounting plate 103 includes a main body portion 1031 extending along a second direction for connecting with the clamping member 201, and a subordinate portion 1032 disposed on the main body portion 1031 near the base plate 102, extending from the first direction away from the main body portion 1031, for connecting with the base plate 102. Multiple mounting plates 103 are disposed on the base plate 102 and spaced apart along a third direction.

[0037] It should be mentioned that the first direction in this embodiment is the width direction of the base 100, the second direction in this embodiment is the height direction of the base 100, and the third direction in this embodiment is the length direction of the base 100.

[0038] Combination Figure 5 as well as Figure 6As shown, in some exemplary embodiments, the locking part 400 includes a first wedge block 4021 slidably disposed on the base 100 along a first direction, a second wedge block 4011 adapted to the first wedge block 4021 and slidably disposed on the clamping member 201 along a second direction, a locking pin 4013 disposed on the second wedge block 4011, and a locking hole 104 disposed on the base 100. In the locked state, the locking pin 4013 is inserted into the locking hole 104, and the driving end of the first driving part 300 extends to push the first wedge block 4021 to slide, thereby driving the second wedge block 4011 to drive the locking pin 4013 to slide and disengage from the locking hole 104. The advantage of this arrangement is that it makes the locking part 400 structurally simple and reliable in locking. The design of the wedge block also facilitates the smooth disengagement of the locking pin 4013 during unlocking and enables automatic unlocking, thereby improving production efficiency.

[0039] In a specific implementation, the locking part 400 of this embodiment includes a vertical plate 401 extending along a second direction on the side wall of the base plate 102, and a flat plate 402 extending along a first direction at the bottom of the vertical plate 401 along the second direction. A first wedge block 4021 is slidably disposed on the flat plate 402 along the first direction, and a second wedge block 4011 is slidably disposed on the vertical plate 401 along the second direction. The top of the second wedge block 4011 is also provided with a connecting block 4012 extending along a third direction, and both ends of the connecting block 4012 are provided with locking pins 4013. The flat plate 402 is also provided with a clearance through hole 4022 for avoiding the locking pins 4013. The locking pins 4013 can pass through the clearance through hole 4022 and be inserted into the locking hole 104, thereby achieving locking.

[0040] Furthermore, in this embodiment, the first wedge block 4021 is also provided with a push post 4023. The push post 4023 is located on the side wall of the first wedge block 4021 away from the second wedge block 4011 and extends in the first direction away from the first wedge block 4021. The extended drive end of the first drive unit 300 can push the push post 4023 to make the first wedge block 4021 slide, thereby driving the second wedge block 4011 to slide in the second direction, which in turn can drive the locking pin 4013 to slide in the second direction, so that the locking pin 4013 can disengage from the locking hole 104, thereby completing the unlocking. It is worth mentioning that in this embodiment, the two sides of the connection portion 20272 between the vertical plate 401 and the flat plate 402 are also provided with reinforcing ribs 403 to improve the structural strength of the connection between the vertical plate 401 and the flat plate 402.

[0041] Continue to combine Figures 5 to 6As shown, in some exemplary embodiments, the traction unit 500 includes an adsorption plate 502 slidably disposed on the clamping member 201 along a first direction, an elastic member 503 disposed between the adsorption plate 502 and the clamping member 201, and a magnet 3021 disposed on the driving end of the first driving unit 300. The adsorption plate 502, attracted by the magnet 3021, drives the clamping member 201 to slide along the first direction with the driving end of the first driving unit 300. This configuration allows the elastic member 503 to buffer impacts, ensuring smooth sliding of the clamping member 201. It also simplifies the structure of the traction unit 500, enabling a reliable connection between the adsorption plate 502 and the driving unit, thereby improving the motion reliability of the traction unit 500.

[0042] In specific implementation, in detail, it is also combined with Figure 5 and Figure 6 As shown, the aforementioned adsorption plate 502 is disposed on the flat plate 402, including a vertical plate 501 disposed at one end of the flat plate 402 away from the vertical plate 401, and a weight reduction groove 5011 is provided in the middle of the vertical plate 501.

[0043] The adsorption plate 502 is connected to a first guide post 5021 at one end near the upright plate 501. Multiple first guide posts 5021 are spaced apart along the length of the adsorption plate 502 and extend towards one side of the upright plate 501. The upright plate 501 has a first guide hole 5012 for the first guide post 5021 to pass through. The other end of the first guide post 5021 also has a limiting protrusion 20222, the diameter of which is larger than the diameter of the first guide hole 5012. This allows the adsorption plate 502 to slide along a first direction. The elastic member 503 is sleeved on the first guide post 5021 and positioned between the upright plate 501 and the adsorption plate 502. A transmission column 5022 is also provided between the adsorption plate 502 and the flat plate 402. One end of the transmission column 5022 abuts against the adsorption plate 502 and is fixedly connected to the adsorption plate 502, and the other end can abut against the flat plate 402 to transmit the power of the first driving part 300. The top of the upright plate 501 in this embodiment is also provided with a limiting bolt 5013 for limiting the adsorption plate 502. Its related structure can refer to the existing limiting bolt 5013.

[0044] Furthermore, in specific implementation of this embodiment, the first driving unit 300 includes a mounting base 301 and a first cylinder 302 mounted on the mounting base 301, capable of extending and retracting in a first direction. A magnet 3021 is mounted on the driving end of the first cylinder 302. The driving end also has a striking pin block 3022 for pushing against the push post 4023, with the striking pin block 3022 correspondingly positioned to push against the post 4023. The driving end also has protective posts 3023 for protecting the magnet 3021, located on both sides of the magnet 3021, and their length should exceed the thickness of the magnet 3021. This prevents the magnet 3021 from breaking due to impact, thus improving the reliability of the assembly fixture. The mounting base 301 also has a photoelectric switch 303 for detecting the position of the driving end. It should be noted that the first driving unit 300 in this embodiment can be a cylinder with a guide rod; its related structure can refer to existing cylinders with guide rods.

[0045] In addition, it is worth mentioning that the elastic element 503 and the magnet 3021 in this embodiment can be springs and electromagnets 3021, which are well known to those skilled in the art. Of course, they can also be buffer rubber, etc., as long as they can buffer the impact, achieve smooth movement, and attract the adsorption plate 502. They will not be described in detail here.

[0046] Combination Figure 2 as well as Figure 4 As shown, in some exemplary embodiments, the base 100 is provided with a first lifting part 105, and the lifting end of the first lifting part 105 is provided with a fixing part 109 for fixing the engine, and clamping members 201 are provided on two opposite sides of the lifting part.

[0047] In this way, the height adjustment of the lifting unit facilitates the production of straddle-type vehicles, improves the adaptability of assembly tooling, reduces adjustment costs caused by vehicle or component changes, facilitates the installation of engines and wheels, simplifies the assembly process, and helps improve overall production efficiency.

[0048] In specific implementation, the first lifting part 105 of this embodiment can be a scissor lift platform well known to those skilled in the art. Of course, it can also be other lifting mechanisms, as long as they can meet the height adjustment requirements, which will not be elaborated here.

[0049] Combination Figures 1 to 4 ,as well as Figures 11 to 13As shown, in some exemplary embodiments, the base 100 has a receiving cavity 106 and a cover 107 that covers the receiving cavity 106 and can be opened and closed. A lifting unit is located within the receiving cavity 106. The advantage of this arrangement is that it allows vehicles to travel out of the production line via a platform, which is beneficial for both improving product quality and increasing production efficiency.

[0050] In specific implementation, in detail, combined with Figure 2 , Figure 3 ,as well as Figures 11 to 13 As shown, the openable and closable cover 107 includes guide rail assemblies 108 on both side walls along the length of the receiving cavity 106, a positioning post 1071 on one end along the width of the cover 107, and a pulley assembly 1072 on the other end along the width of the cover 107. The guide rail assembly 108 includes a guide rail body and a slide rail 1081 on the side wall away from the base 100. The pulley assembly 1072 can cooperate with the slide rail 1081, allowing the cover 107 to slide to both sides along the width of the base 100, thereby achieving opening and closing. The end of the slide rail 1081 is also provided with a limiting stop 1082 to limit the pulley assembly 1072 and prevent it from dislodging from the slide rail 1081, thus affecting production safety.

[0051] In addition, the slide rail 1081 assembly is provided with limiting grooves 1083 at both ends, which cooperate with the positioning post 1071. The positioning post 1071 can be driven into or out of the limiting groove 1083 by external force. The opening of the limiting groove 1083 is also provided with a through hole 1084. The limiting pin 1092 can pass into the through hole 1084 and block the opening of the limiting groove 1083 to prevent the positioning post 1071 from leaving the limiting groove 1083. This achieves the positioning of the cover plate 107.

[0052] In practical operation, when it is necessary for the cover plate 107 to no longer obstruct the receiving cavity 106, simply pull out the limiting pin 1085 and slide the positioning post 1071 out of the limiting groove 1083. The cover plate 107 can then slide along the guide of the slide rail 1081, i.e., in the width direction of the base 100. When the pulley assembly 1072 abuts against the limiting stop 1082, the cover plate 107 is in the open state. At this time, simply let the cover plate 107 hang down naturally under gravity, and the cover plate 107 will fold onto the side of the base 100. Insert the limiting pin 1085 back into the through hole 1084 to complete the opening step. When it is necessary for the cover plate 107 to obstruct the receiving cavity 106, simply refer to the above steps, which will not be repeated here.

[0053] In addition, it is worth mentioning that the cover plate 107 includes a panel and a reinforcing beam 1073 located on the side of the panel near the base 100. The reinforcing beam 1073 is in the form of a grid to improve the overall structural strength of the cover plate 107, so that it can bear the weight of the straddle-type vehicle when it is off the production line, thereby facilitating the vehicle to be off the production line and improving the overall production efficiency.

[0054] Combination Figure 1 , Figure 4 as well as Figure 10 As shown, in some exemplary embodiments, the fixing part 109 includes two fixing posts 1091 disposed opposite to each other, and each fixing post 1091 is provided with a fixing hole 109121 for fixing the engine. The fixing post 1091 is rotatably mounted on the lifting end of the first lifting part 105, and the lifting end of the first lifting part 105 is provided with a limiting pin 1092 detachably inserted into the fixing post 1091, the limiting pin 1092 being able to restrict the rotation of the fixing post 1091.

[0055] This design simplifies the structure of the fixing part 109, ensures reliable positioning, and facilitates the storage of the fixing column 1091 within the receiving cavity 106. This facilitates the formation of a passage platform, which in turn facilitates the off-line production of straddle-type vehicles. This benefits both product quality and production efficiency.

[0056] In specific implementation, in detail, combined with Figure 4 As shown, the fixing post 1091 in this embodiment includes a connecting section 10911 extending along the height direction of the base 100, and a fixing section 10912 extending away from the connecting section 10911 along the length direction of the base 100. Two fixing holes 109121 are spaced apart on the fixing section 10912 along the length direction of the base 100. The connecting section 10911 also has two limiting holes 109111 for engaging with the limiting pin 1092, spaced apart along the height direction of the base 100. Of course, the specific number or spacing of the fixing holes 109121 and the limiting holes 109111 can be adjusted adaptively, as long as the reliability of engine fixing and the rotatable mounting of the fixing post 1091 on the lifting end of the first lifting part 105 are satisfied.

[0057] The fixing part 109 in this embodiment further includes a base 1093 fixed to the lifting end, and a connector 1094 provided on the base 1093 for connecting the base 1093 and the fixing post 1091. The connector 1094 has a receiving groove 10941. The connecting section 10911 of the fixing post 1091 is provided in the receiving groove 10941. Limiting through holes 10942 are provided on both sides of the receiving groove 10941 to match the limiting holes 109111. The limiting pin 1092 can pass through the limiting through hole 10942 into the limiting hole 109111, thereby restricting the rotation of the fixing post 1091. When it is necessary to store the fixing post 1091, it is only necessary to pull out the limiting pins 1092 that are set along the height direction of the base 100 except for the bottommost limiting pin 1092, so that the fixing post 1091 can rotate relative to the first lifting part 105. This makes it easier to house the fixed column 1091 into the receiving cavity 106, and facilitates the formation of the platform.

[0058] Combination Figure 5 , Figure 9 as well as Figure 10 As shown, in some exemplary embodiments, the clamping member 201 includes a fixing plate 2021 slidably disposed on the base 100 along a first direction, a clamping plate 2022 slidably disposed on the fixing plate 2021 along the first direction, and a push rod 2023 screwed onto the fixing plate 2021. The clamping plate 2022 is used to clamp the wheel, and the push rod 2023 is used to push the clamping plate 2022. Operating the push rod 2023 can adjust the distance between the clamping plates 2022 in the two clamping members 201. This configuration is simple in structure, easy to design and implement, and easy to adjust, allowing the clamping member 201 to be applicable to wheels of different sizes. This improves production efficiency and the versatility of the assembly tooling, which is beneficial for production cost control.

[0059] In specific implementation, one end of the push rod 2023 can abut against the clamping plate 2022. The fixing plate 2021 has a first clearance hole 20211. The threaded sleeve 20212 is coaxially arranged with the first clearance hole 20211. The push rod 2023 is screwed to the threaded sleeve 20212. The end of the threaded sleeve 20212 away from the fixing plate 2021 is provided with a fastening nut 2024 to lock the push rod 2023 and prevent the clamping plate 2022 from moving. When it is necessary to adjust the position of the clamping plate 2022, simply loosen the fastening nut 2024, and then rotate the push rod 2023. The push rod 2023 will then push the clamping plate 2022, making it closer to or away from the wheel. Then, tighten the fastening nut 2024 again to complete the adjustment.

[0060] Furthermore, the aforementioned clamping components include a front wheel clamping component 201 and a rear wheel clamping component 201, both of which include the aforementioned fixing plate 2021, clamping plate 2022, and other components. They also have a guiding assembly and a pad 2025 disposed on the clamping plate 2022 near the wheel. Specifically, the guiding assembly includes a second guide post 20221 fixed to the clamping plate 2022, with the second guide post 20221 disposed on both sides of the clamping plate 2022. The fixing plate 2021 has a second guide through hole 20213 that cooperates with the second guide post 20221, and a guide sleeve 20214 coaxially disposed with the second guide through hole 20213. The second guide post 20221 can pass through the second guide through hole 20213 and into the guide sleeve 20214, thereby guiding the movement of the clamping plate 2022. The second guide post 20221 is also provided with a limiting protrusion 20222 at the end away from the clamping plate 2022. The diameter of the limiting protrusion 20222 is larger than the diameter of the second guide post 20221, so as to prevent the second guide post 20221 from coming out of the guide sleeve 20214.

[0061] The aforementioned pad 2025 is typically made of nylon material well known to those skilled in the art to prevent scratches on the tires or rims. Of course, it can also be made of other flexible materials well known to those skilled in the art.

[0062] The difference between the front wheel clamping component 201 and the rear wheel clamping component 201 lies in that the aforementioned front wheel clamping assembly is further provided with a protective cover 2026. The aforementioned fixing plate 2021 is also provided with support columns 20215 for mounting the protective cover 2026. The support columns 20215 are located at the end of the fixing plate 2021 away from the base 100, and are spaced apart along the length of the fixing plate 2021, extending away from the wheel. The protective cover 2026 is provided on the support columns 20215 and covers the aforementioned screw and guide assembly to prevent them from deforming or being damaged by external forces, resulting in unstable clamping force or injury to personnel. Of course, the aforementioned rear wheel clamping component 201 can also be provided with a protective cover 2026; this is only a preferred embodiment and is not intended to limit the rear wheel clamping component 201 or the front wheel clamping assembly.

[0063] The aforementioned rear wheel clamping member 201 has clearance notches in the middle of the fixing plate 2021, clamping plate 2022, and pad 2025 to avoid wheel hubs and vehicle drive components. The fixing plate 2021 also has an extension section 20216 extending along the length direction of the base 100, which is inclined from bottom to top away from the fixing plate 2021. At the same time, the rear wheel clamping member 201 also has limiting baffles 2027 at both ends in the length direction to restrict the movement of the rear wheels of the vehicle in the length direction of the base 100. The limiting baffles 2027 include a baffle body 20271 extending along the width direction of the base 100, and a connecting portion 20272 located at the end of the baffle body 20271 near the fixing plate 2021 and extending in the length direction of the base 100. The connecting portion 20272 is screwed to the extension section 20216. Thus, by setting the limit baffle 2027, the clamping reliability of the rear wheel clamp 201 can be improved, thereby enhancing the safety of the clamping component.

[0064] In some exemplary embodiments, the base 100 is an automated guided vehicle (AGV). This arrangement offers the advantage of increased production line flexibility and automation, facilitating the removal of straddle-type vehicles from the production line and thus contributing to further improvements in production efficiency.

[0065] In specific implementation, the automated guided vehicle of this embodiment also includes a pathfinding component, a power component, etc. Other related components not mentioned herein can be found in existing automated guided vehicles and will not be described in detail here.

In the locked state, the locking pin 4013 is inserted into the locking hole 104, and the driving end of the first driving part 300 extends to push the first wedge block 4021 to slide, thereby driving the second wedge block 4011 to drive the locking pin 4013 to slide and disengage from the locking hole 104. The traction part 500 includes an adsorption plate 502 slidably disposed on the clamping member 201 along a first direction, an elastic member 503 disposed between the adsorption plate 502 and the clamping member 201, and a magnet 3021 disposed on the driving end of the first driving part 300. The adsorption plate 502 can drive the clamping member 201 to slide along the first direction with the driving end of the first driving part 300 under the attraction of the magnet 3021.

[0068] The base 100 is provided with a first lifting part 105, and the lifting end of the first lifting part 105 is provided with a fixing part 109 for fixing the engine.

The fixing part 109 includes two fixing posts 1091 arranged opposite to each other, and each fixing post 1091 is provided with a fixing hole 109121 for fixing the engine. The fixing post 1091 is rotatably mounted on the lifting end of the first lifting part 105, and a limiting pin 1092 is provided on the lifting end of the first lifting part 105 and is detachably inserted into the fixing post 1091. The limiting pin 1092 can restrict the rotation of the fixing post 1091.

The first guide rods 7031 can pass through the second clearance hole 7011, thereby guiding the movement of the drive plate 703. A first limiting ring 7032 is also provided at the end of the first guide rod 7031 away from the drive plate 703. The diameter of the first limiting ring 7032 is larger than the diameter of the second clearance hole 7011 to prevent the first guide rod 7031 from dislodging from the second clearance hole 7011.

[0075] Combination Figure 17 As shown, it also includes a third drive unit 800 fixed to one side of the base 100 in a third direction, and a stop member 803 provided at the drive end of the third drive unit 800. The third drive unit 800 can drive the stop member 803 to extend and retract in a third direction. The advantage of this arrangement is that it ensures that the automated guided vehicle will not shift when it leaves the production line, which helps to further improve the safety of the production line.

[0076] In specific implementation, the third drive unit 800 includes a mounting base 801, a third cylinder 802 mounted on the mounting base 801, and a hinge connecting plate 804 located at the cylinder's extended end. It also includes a first hinge mounting rod 805, one end of which is fixed to the mounting base 801 and located on both sides of the third cylinder 802, and a second hinge mounting rod 806, one end of which is fixed to a stop member 803 and correspondingly located to the first hinge mounting rod 805.

The second guide rods 8031 ​​can pass through the third clearance hole 8011, thereby guiding the movement of the stop member 803. The end of the second guide rod 8031 ​​away from the clamping plate 2022 is also provided with a second limiting ring 8032. The diameter of the second limiting ring 8032 is larger than the diameter of the third clearance hole 8011 to prevent the second guide rod 8031 ​​from dislodging from the third clearance hole 8011.

[0078] In detail, during the actual off-line process, after the automated guided vehicle (AGV) carries the assembled and visually inspected motorcycle to the off-line equipment marker, the rear anti-intrusion barrier 1100 is raised. After the photoelectric switch 303 determines that the AGV is in the correct parking position and there are no obstacles in front or behind, and the laser scanner 1200 determines that there are no obstacles or operators on the left or right sides of the AGV, the control center commands the AGV to enter a dormant state and executes the next step, the second lifting unit 600 lowers, so that the upper surface of the AGV is parallel to the ground, and the pedal 704 extends to ensure that there is no danger to the operator between the sides of the AGV and the off-line equipment.

[0079] After pedal 704 is in position, all detection switches are in normal position, and the tri-color light 900 flashes green, indicating that the operator can enter the off-line equipment. The operator rides the motorcycle, and after confirming that both legs are on the ground and that the motorcycle will not tip over, the operator presses the release button 1000. The first drive unit 300 unlocks the locking unit 400, and the clamping assembly 200 is opened through the traction unit 500. The operator then starts the motorcycle and rides it off the line.

[0080] When a person accelerates forward on a motorcycle, it will exert a backward force on the automated guided vehicle below. At this time, the stop 803 that blocks the automated guided vehicle will take effect, ensuring that the automated guided vehicle will not reverse.

[0081] After the operator has completely driven the automated guided vehicle (AGV), photoelectric switch 303 detects no obstacles in front and behind, laser scanner 1200 detects no obstacles to the left and right, photoelectric switch 303 at the first drive unit 300 confirms that the device has not extended, stop 803 reaches the origin position, and the second lifting unit 600 automatically rises. When the lifting end of the second lifting unit 600 is level with the ground, the position switch is triggered, the control center commands the AGV to change from sleep mode to normal working mode, and issues a release command. After the AGV drives out, the anti-intrusion barrier 1100 lowers, waiting for the next AGV to enter the workstation.

[0082] Related devices not mentioned in the offline structure of this embodiment, such as the anti-intrusion baffle 1100 and the laser scanner 1200, can all be referred to the related structures of the anti-intrusion baffle 1100 and the laser scanner 1200 that are well known to those skilled in the art, and will not be described in detail here.

[0083] The vehicle off-line device of this embodiment, by setting a second lifting part 600 in the pit and the assembly fixture described in any one of the above, and the assembly fixture being set at the lifting end of the second lifting part 600, can save ground space and facilitate worker operation, thereby improving production efficiency.

[0084] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
