Description

Technical Field

[0001] This invention relates to the field of server chassis production loading and conveying equipment technology, specifically an automated guided vehicle for server chassis production. Background Technology

[0002] In the server chassis manufacturing process, the server chassis and its supporting tooling plates need to be precisely and efficiently transferred between multiple production processes such as stamping, assembly, testing, and packaging. Currently, the industry mostly uses manually pushed transfer vehicles or ordinary AGV transport vehicles for transfer operations. Manually pushed transfer vehicles are not only labor-intensive and inefficient, but also prone to damage to the server chassis due to human error. While ordinary AGV transport vehicles can reduce human intervention, existing technologies still have many significant shortcomings and cannot meet the transfer requirements of large-scale server chassis production, as detailed below: 1. The auxiliary support structure of ordinary AGV transport vehicles is mostly fixed and cannot be flexibly extended and adjusted according to the width of the transfer site and the load. When transferring heavy server chassis and tooling plates, the center of gravity is prone to shift, causing the AGV transport vehicle to shake, resulting in poor stability and safety hazards such as equipment damage and collisions with server chassis. In particular, when adapting to production channels of different widths, the fixed support structure cannot be flexibly adjusted and is prone to interference with surrounding equipment, further limiting the flexibility of transfer.

[0003] 2. Existing AGV transport vehicles are mostly single-carrying vehicles, either only capable of carrying their own cargo or only able to lift external load-bearing structures, resulting in poor adaptability. Regarding external load-bearing structures, the positioning connection between the load-bearing structure and the AGV body is not secure enough, making them prone to shifting during transport. Furthermore, the width of the auxiliary support cannot be flexibly adjusted according to the lifting load, leading to AGV body swaying during lifting and poor stability during the transport of server chassis and tooling plates.

[0004] Therefore, there is an urgent need for an automated guided vehicle for server chassis production that can balance the movement of its own load-bearing structure with the lifting and supporting structure, and improve the stability and efficiency of transportation. Summary of the Invention

[0005] The purpose of this invention is to provide an automated guided vehicle for server chassis production, in order to solve the problems mentioned in the background art, such as the inability of existing automated guided vehicles to simultaneously handle the movement of their own load and the lifting support structure, as well as the poor stability of the transfer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated guided vehicle (AGV) for server chassis manufacturing includes an AGV body assembly and further includes: Auxiliary wheel side extension drive assembly, wherein the auxiliary wheel side extension drive assembly is symmetrically arranged at both ends inside the AGV body assembly; An auxiliary side wheel assembly is connected to the auxiliary wheel side extension drive assembly and is installed on both sides of the AGV body assembly.

[0010] As a preferred embodiment of the automated guided vehicle for server chassis production according to the present invention, the auxiliary side wheel assembly includes a side wheel seat, a side extension traction arm, and a lifting part. The side wheel seat is disposed in the auxiliary side wheel mounting slot, the side extension traction arm is disposed at one end of the side wheel seat, and the lifting part is detachably mounted on the side wheel seat.

[0011] As a preferred embodiment of the automated guided vehicle for server chassis production described in this invention, the side wheel seat includes a side extension seat and a swivel wheel.

[0013] As a preferred embodiment of the automated guided vehicle for server chassis production described in this invention, the lifting unit includes an electric telescopic cylinder and a top plate. The electric telescopic cylinder is fixedly installed in the lifting mounting position, with its telescopic end facing upward and fixedly connected to the top plate.

[0014] As a preferred embodiment of the automated guided vehicle for server chassis production according to the present invention, the load-bearing frame includes a rack fence and a lower insertion positioning part, wherein the lower insertion positioning part is disposed at the lower end of the rack fence; The frame enclosure includes a vertical post, a lower panel, an upper panel, and a base support sleeve.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The auxiliary wheel side extension drive components are symmetrically built into the drive component installation compartment of the AGV body assembly.

The width of the auxiliary support can be precisely adjusted according to the load weight and the width of the transfer site for two working conditions: carrying its own cargo and moving the lifting load-bearing frame. With the coordinated rolling of the drive wheel and the omnidirectional wheel, it effectively avoids problems such as center of gravity shift, vehicle body swaying, and tipping that are prone to occur in existing fixed support structures, providing stable support for the transfer process.

[0017] This invention enables diversified operation modes for the AGV body assembly itself carrying goods, the carrying frame independently carrying goods, and the AGV body assembly lifting and moving the carrying frame. The transfer mode can be flexibly switched according to production process requirements and goods specifications, without the need for additional auxiliary equipment. This effectively solves the problems of the single carrying mode and poor adaptability of existing automated guided vehicles, significantly improving production transfer cycle time. The traction transmission mechanism uses a servo motor and dual adjustable screws to achieve synchronous extension of the auxiliary side wheel assemblies on both sides, resulting in high adjustment efficiency and accuracy, eliminating the need for manual adjustment. The lifting unit and the auxiliary side wheel assemblies work together to achieve integrated operation of lifting and moving the carrying frame of the AGV body assembly, with a high degree of automation throughout the process, reducing manual intervention and further improving transfer efficiency.

[0018] By precisely inserting the positioning pins of the lower positioning part into the countersunk holes of the vehicle body load plate, and with the squeezing and pushing action of the airbag, the positioning connection between the load-bearing frame and the AGV vehicle body assembly is achieved, completely solving the problem of displacement of the existing load-bearing structure and the automated guided vehicle during movement, and ensuring that the load-bearing frame is stable and does not shift during the transfer process; when the AGV vehicle body assembly is carrying its own cargo, the vehicle body load plate is flat and firm, and can directly and stably support the server chassis and tooling plates.

Figure 2 - Figure 4 As shown, the AGV vehicle body assembly 100 includes a vehicle body mounting base 110, a drive wheel 120, and a vehicle body load plate 130; The vehicle body mounting base 110 has a drive component mounting compartment 111 inside, and auxiliary side wheel mounting slots 112 are symmetrically opened on both sides. The auxiliary side wheel mounting slots 112 have through slots 113, which are connected to the drive component mounting compartment 111. A hinged support 114 is fixedly welded inside the auxiliary side wheel mounting slots 112. The drive wheel 120 is rotatably mounted on both sides of the vehicle body mounting base 110; The vehicle body load plate 130 is detachably installed on the top of the vehicle body mounting base 110. Lifting clearance openings 131 are provided on both sides of the load plate 130. A positioning countersunk hole 132 is provided in the middle of the upper end face of the load plate 130. The positioning countersunk hole 132 is used to achieve positioning connection with the load-bearing railing 400. The lifting clearance opening 131 is used to avoid the lifting action of the auxiliary side wheel assembly 300.

[0024] In some embodiments of the present invention, reference is made to... Figure 5 - Figure 7 As shown, the auxiliary wheel side extension drive assembly 200 includes a base platform 210 and a traction transmission mechanism 220; The base platform 210 is a rectangular rigid base, which is fixedly assembled into the drive component mounting compartment 111 by bolts; The traction drive mechanism 220 is mounted on the base platform 210 and is used to connect with the auxiliary side wheel assembly 300.

[0025] The traction transmission mechanism 220 includes a servo motor 221, a coupling 222, an adjusting screw 223, a bearing seat 224, a screw nut seat 225, a connecting rod connector 226, and a guide assembly. The output end of the servo motor 221 is connected to the coupling 222, which is installed in the middle of the base platform 210. The adjusting screw 223 is installed on both sides of the coupling 222 and is connected to the coupling 222 for transmission. The two ends of the adjusting screw 223 are rotatably equipped with bearing seats 224, which are fixed on the base platform 210. The screw nut seat 225 is threaded onto the adjusting screw 223. The connecting rod connector 226 is detachably connected to both sides of the screw nut seat 225. The guide assembly includes a positioning sleeve 227, a guide post 228, and a guide post mounting base 229. The guide post mounting base 229 is installed on the side wall of the drive assembly mounting compartment 111. The guide post 228 is horizontally fixed between two guide post mounting bases 229. The positioning sleeve 227 is slidably sleeved on the guide post 228, and the positioning sleeve 227 is connected to the connecting rod connector 226 installed on the side of the lead screw nut seat 225 to provide smooth guidance for the movement of the lead screw nut seat 225.

[0026] The auxiliary wheel side extension drive assembly 200 is symmetrically built into the drive assembly installation compartment 111 of the AGV body assembly 100. This not only avoids the interference of debris and dust on the drive structure in the production site, but also enables the auxiliary side wheel assembly 300 to extend flexibly through the traction transmission mechanism 220. The width of the auxiliary support can be precisely adjusted according to the load weight and the width of the transfer site for two working conditions: its own load and the movement of the lifting load-bearing railing 400. With the coordinated rolling of the drive wheel 120 and the universal wheel 312, it effectively avoids the problems of center of gravity shift, vehicle body swaying, and tipping that are prone to occur in the existing fixed support structure, and provides stable support for the transfer process.

[0027] In some embodiments of the present invention, reference is made to... Figure 5 - Figure 7 As shown, the auxiliary side wheel assembly 300 includes a side wheel seat 310, a side extension traction arm 320, and a lifting part 330. The side wheel seat 310 is disposed in the auxiliary side wheel mounting slot 112, the side extension traction arm 320 is disposed at one end of the side wheel seat 310, and the lifting part 330 is detachably mounted on the side wheel seat 310.

[0028] The side wheel seat 310 includes a side extension seat 311 and a caster wheel 312. The side extension seat 311 is a rigid structure, with one end connected to the connecting arm 323 and the bottom of the other end equipped with a caster wheel 312. The side extension seat 311 also has a lifting mounting position 313 for installing the lifting part 330.

[0029] The lateral extension traction arm 320 includes an arm body connecting end 321, a transverse traction rod 322, and a connecting arm 323. The arm body connecting end 321 is fixedly welded to one end of the lateral extension seat 311 and is hinged to the hinge support 114. One end of the transverse traction rod 322 is hinged to the arm body connecting end 321, and the other end is fixedly connected to the connecting arm 323 by bolts. The other end of the connecting arm 323 is connected to the connecting rod connector 226 on one side of the screw nut seat 225.

[0030] The lifting unit 330 includes an electric telescopic cylinder 331 and a top plate 332. The electric telescopic cylinder 331 is fixedly installed in the lifting installation position 313, with its telescopic end facing upward and fixedly connected to the top plate 332. The top plate 332 is a non-slip rigid plate used to lift the load-bearing railing 400.

[0031] In some embodiments of the present invention, reference is made to... Figure 8 - Figure 9 As shown, the load-bearing frame 400 includes a frame fence 410 and a lower insertion positioning part 420, which is disposed at the lower end of the frame fence 410; The frame enclosure 410 includes a vertical post 411, a lower panel 412, an upper panel 413, and a foot support sleeve 414. The lower panel 412 and the upper panel 413 are respectively horizontally fixed to the lower and upper parts of the vertical post 411, and the foot support sleeve 414 is fixedly installed at the bottom of the vertical post 411.

[0032] This invention enables diversified operation modes for the AGV body assembly 100 to carry goods itself, the carrying frame 400 to carry goods independently, and the AGV body assembly 100 to lift and move the carrying frame 400. The transfer mode can be flexibly switched according to production process requirements and cargo specifications, without the need for additional auxiliary equipment. This effectively solves the problems of single cargo-carrying modes and poor adaptability of existing automated guided vehicles, significantly improving production transfer cycle time. The traction transmission mechanism 220 is driven by a servo motor 221 and dual adjusting screws 223, enabling the synchronous extension of the auxiliary side wheel assemblies 300 on both sides. This provides high adjustment efficiency and precision, eliminating the need for manual adjustment. The lifting part 330 works in conjunction with the auxiliary side wheel assemblies 300 to achieve integrated operation of lifting and moving the carrying frame 400 from the AGV body assembly 100. This highly automated process reduces manual intervention and further improves transfer efficiency.

[0033] The lower positioning part 420 includes a guide post 421, a tray 422, an airbag 423, and a positioning pin 424. The guide post 421 is vertically fixed to the lower end face of the lower panel 412. The tray 422 is parallel to the lower end of the lower panel 412, and the four corners of the tray 422 are slidably engaged with the guide post 421. The airbag 423 is fixedly installed on the lower end face of the lower panel 412. The positioning pin 424 is assembled in the middle of the airbag 423. The tray 422 has a center for positioning. The positioning post 424 has a clearance hole for making way. A return spring 425 is fitted on the positioning post 424. The upper end of the return spring 425 is connected to the upper end of the positioning post 424, and the lower end of the return spring 425 is connected to the tray 422. The lifting part 330 lifts the tray 422, and the tray 422 compresses the airbag 423. The airbag 423 presses down on the positioning post 424, and the positioning post 424 is positioned and inserted into the positioning countersunk hole 132.

[0034] The positioning pin 424 of the lower positioning part 420 is precisely inserted into the positioning countersunk hole 132 of the vehicle body load plate 130. With the squeezing and pushing action of the airbag 423, the positioning connection between the load-bearing frame 400 and the AGV vehicle body assembly 100 is realized. This completely solves the problem of displacement of the existing load-bearing structure and the automated guided vehicle during movement, ensuring that the load-bearing frame 400 is stable and does not shift during the transfer process. When the AGV vehicle body assembly 100 is carrying its own cargo, the vehicle body load plate 130 is flat and firm, and can directly and stably support the server chassis and tooling plate.

[0035] Specific usage of this invention: I. AGV vehicle body assembly 100 self-carrying mode: Adjust the extension width of the auxiliary side wheel assembly 300 according to the width of the transfer site and the weight of the load. Start the servo motor 221, which drives the adjusting screws 223 on both sides to rotate synchronously through the coupling 222. The screw nut seat 225 moves linearly along the adjusting screw 223, causing the connecting rod connector 226 and the positioning sleeve 227 to slide along the guide post 228. The connecting rod connector 226 drives the arm connecting end 321 to rotate around the hinge support 114 through the connecting arm 323 and the transverse traction rod 322, thereby causing the side wheel seat 310 to extend horizontally until the universal wheel 312 reaches the appropriate support position. Then, turn off the servo motor 221 to complete the width adjustment of the auxiliary side wheel assembly 300. At this time, the lifting part 330 remains in the retracted state, and the top plate 332 is located below the lifting clearance opening 131, which does not affect the load on the vehicle body load plate 130.

[0036] Place the server chassis and tooling plate directly on the vehicle body load plate 130, ensuring that the placement is stable and without deviation; start the drive wheel 120 of the AGV vehicle body assembly 100 to move the entire equipment. According to the preset transfer route, the equipment automatically travels to the designated process position.

[0037] II. Load-bearing frame with 400 independent cargo capacity + AGV body assembly with 100 lifting and moving mode: The load-bearing frame 400 is placed independently on the ground and its stability is ensured by the foot support sleeve 414. The server chassis and tooling plate are placed on the lower plate 412 and upper plate 413 of the load-bearing frame 400 to complete the independent loading of the load-bearing frame 400.

[0038] Start the AGV body assembly 100 and control it to move to the lower end of the ground-mounted load-bearing frame 400. Adjust the position of the AGV body assembly 100 so that the lifting parts 330 on both sides are aligned with the tray 422 at the lower end of the load-bearing frame 400, ensuring that the top plate 332 is aligned with the tray 422. According to the weight and size of the load-bearing frame 400, start the servo motor 221 and adjust the auxiliary side wheel assembly 300 to extend appropriately, thereby improving the support stability of the AGV body assembly 100 and adapting to the lifting and load-bearing requirements.

[0039] Activate the electric telescopic cylinder 331. The telescopic end of the electric telescopic cylinder 331 extends upward, driving the top plate 332 to move upward. The top plate 332 passes through the lifting clearance port 131 and contacts the pallet 422, and continues to lift the pallet 422. The pallet 422 slides upward along the guide column 421, compressing the airbag 423. After being compressed, the airbag 423 pushes the positioning pin 424 downward, so that the positioning pin 424 passes through the clearance hole of the pallet 422 and is accurately inserted into the positioning countersunk hole 132 of the vehicle body load plate 130, realizing the positioning connection between the load-bearing railing 400 and the AGV vehicle body assembly 100. Continue to control the electric telescopic cylinder 331 to extend, so that the load-bearing railing 400 is lifted off the ground and the foot support sleeve 414 is lifted off the ground by a certain distance. Then close the electric telescopic cylinder 331.

[0040] Start the drive wheel 120 of the AGV body assembly 100 to move the entire equipment. According to the preset transfer route, the equipment will automatically travel to the designated process position.

[0041] After the equipment reaches the designated position, the drive of the drive wheel 120 is stopped, and the electric telescopic cylinder 331 is activated, causing the telescopic end of the electric telescopic cylinder 331 to retract downwards. The top plate 332 moves downwards, and the load-bearing frame 400 falls down until the foot support sleeve 414 contacts the ground and is stably placed on the ground. The electric telescopic cylinder 331 continues to retract, and the tray 422 slides downwards along the guide column 421 under its own weight. The airbag 423 is decompressed and returns to its original state. The compressed return spring 425 returns to its original state and drives the positioning pin 424 to move upwards and reset. The positioning pin 424 is pulled out from the positioning countersunk hole 132, and the positioning connection between the load-bearing frame 400 and the AGV body assembly 100 is released. The AGV body assembly 100 is controlled to withdraw from the lower end of the load-bearing frame 400, completing the unloading of the load-bearing frame 400.

[0042] Once the load-bearing frame 400 is moved to the designated position, it can carry loads independently.
