Description

Technical Field

[0001] This invention relates to the field of automated guided vehicles (AGVs), and more specifically to a loading guide vehicle for a tempered glass production line. Background Technology

[0002] In the tempered glass production process, the loading stage usually relies on manual handling or semi-automated conveying equipment, which results in problems such as high labor intensity, low efficiency, and poor positioning accuracy. In particular, during the process of transferring glass from a fixed conveyor line to a mobile carrier (such as an AGV), existing technologies mostly use manual operation or simple mechanical pushing, which not only easily leads to scratches on the glass surface and damage to the edges and corners, but also poses safety hazards.

[0003] Furthermore, due to the large size, heavy weight, and high fragility of tempered glass, traditional transfer methods often fail to achieve a smooth, centered, and vibration-free connection, easily causing the glass to shift, collide, or even break during transfer, affecting production continuity and product yield. Currently, although some automation solutions attempt to use lifting and translation mechanisms, they still suffer from problems such as complex structures, poor adaptability, inconvenient centering adjustments, and poor integration with conveyor lines, failing to meet the high-efficiency, flexible, and highly reliable operational requirements of modern production lines. Therefore, there is an urgent need for a guiding system capable of automatically, smoothly, and accurately transferring tempered glass between conveyor lines and AGVs to improve the automation level and operational safety of the loading process. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tempered glass production line feeding guide vehicle to solve the problems existing in the background art.

[0006] The lifting mechanism includes a fixed frame and a cable tray. A guide block is fixedly connected to one end of the cable tray, and a strip plate is fixedly connected to the other end of the cable tray.

[0007] The transfer mechanism includes a stabilizing frame and a connecting frame. A sliding block is fixedly connected to one end of the connecting frame, and a positioning plate is fixedly connected to the other end of the connecting frame. A support strip is provided on the positioning plate.

[0008] Preferably, the fixing frame is fixedly installed on the AGV vehicle, and a guide groove is opened inside the fixing frame, and the guide block is slidably installed in the guide groove.

[0009] Preferably, a motor is fixedly installed on the top of the fixed frame, and a threaded rod with its axis arranged vertically is rotatably installed in the guide groove. The top end of the threaded rod passes through the top of the fixed frame and extends upward. The top end of the threaded rod is fixedly connected to the output end of the motor, and a guide block is threadedly installed on the surface of the threaded rod.

[0010] Preferably, multiple strip plates are provided, one of which is fixedly connected to the top of a guide plate. Two guide plates are symmetrically arranged, and the guide plates are divided into inclined sections and parallel sections. The spacing between the inclined sections decreases from left to right.

[0011] Preferably, the conveying mechanism includes a mounting frame on which a conveying roller is mounted, and a power device for providing rotational force to the conveying roller is also provided on the mounting frame.

[0012] Preferably, the mounting bracket has multiple clearance gaps for the cable tray to pass through.

[0013] Preferably, the stabilizing frame is fixedly installed on the AGV vehicle, and a rack and a sliding rod are fixedly installed on the stabilizing frame, with a sliding block sleeved on the surface of the sliding rod.

[0014] Preferably, a second motor is fixedly installed on the top of the sliding block, and a gear is fixedly connected to the output end of the second motor, with the gear meshing with the rack.

[0016] Preferably, each of the two support strips has a trigger ramp on one side close to the other, and a support plane is provided on the top of the support strip.

[0017] The beneficial effects of this invention are: In this invention, the coordinated operation of a lifting mechanism and a transfer mechanism enables automated, high-precision, and damage-free transfer of tempered glass between the conveying mechanism and the AGV (Automated Guided Vehicle), significantly improving the automation level and production continuity of the loading operation. The lifting mechanism uses a motor-driven threaded rod to raise and lower the guide block and bridge, allowing the strip plate to precisely enter the gap between the conveying rollers and lift the glass. The guide plate design automatically centers and corrects the glass, ensuring its upright position and uniform force during transfer, preventing jamming or breakage due to skewing. The transfer mechanism uses a rack and pinion drive to smoothly move the support strip. The support strip employs a trigger-activated inclined surface and a coiled spring reset structure, automatically unfolding and returning to support the glass during lifting, achieving seamless transfer of the glass from the strip plate to the support plane. The process is smooth and requires no manual intervention. The overall system is compact and coordinated, reducing manual labor intensity and operational risks, effectively minimizing vibration and collisions during glass transfer, improving product yield and overall production line efficiency, and is particularly suitable for large-scale, high-paced intelligent tempered glass production lines.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1 to 5 The present invention provides a material feeding guide vehicle for a tempered glass production line, including an AGV vehicle 1, which is equipped with a conveying mechanism 2, a lifting mechanism 3 and a transfer mechanism 4.

[0031] Reference Figures 1 to 7 The lifting mechanism 3 includes a fixed frame 31 and a cable tray 32. One end of the cable tray 32 is fixedly connected to a guide block 34, and the other end of the cable tray 32 is fixedly connected to a strip plate 33.

[0032] The fixed frame 31 is fixedly installed on the AGV vehicle 1. The fixed frame 31 has a guide groove 311 inside. The guide block 34 is slidably installed in the guide groove 311. The motor 36 is fixedly installed on the top of the fixed frame 31. The threaded rod 35 with its axis arranged vertically is rotatably installed in the guide groove 311. The top end of the threaded rod 35 passes through the top of the fixed frame 31 and extends upward. The top end of the threaded rod 35 is fixedly connected to the output end of the motor 36. The guide block 34 is threadedly installed on the surface of the threaded rod 35.

[0033] Multiple strip plates 33 are provided, and a guide plate 37 is fixedly connected to the top of one of the strip plates 33. Two guide plates 37 are symmetrically arranged. The guide plates 37 are divided into inclined sections 371 and parallel sections 372. The spacing of the inclined sections 371 decreases from left to right.

[0034] The conveying mechanism 2 includes a mounting frame 21, on which a conveying roller 22 is mounted. The mounting frame 21 is also provided with a power device 23 for providing rotational force to the conveying roller 22. Multiple clearance gaps 211 are provided on the mounting frame 21 for the passage of the bridge frame 32.

[0035] In summary, the lifting mechanism 3 and the conveying mechanism 2 together constitute the lifting and receiving subsystem for tempered glass from the conveyor line to the AGV vehicle 1. The two are highly coordinated in structure and action, realizing the smooth lifting and precise positioning of the glass.

[0036] The main body of the lifting mechanism 3 includes a fixed frame 31 and a bridge frame 32. The fixed frame 31 is fixed to the chassis of the AGV vehicle 1 by bolts or welding. The guide groove 311 inside the fixed frame 31 is vertical and is used to guide the lifting and lowering movement of the guide block 34. The guide block 34 is fixedly connected to one end of the bridge frame 32, and multiple parallel strip plates 33 are fixedly connected to the other end of the bridge frame 32. A motor 36 is installed on the top of the fixed frame 31. Its output shaft is connected to a threaded rod 35 through a coupling. The threaded rod 35 is vertically inserted into the guide groove 311 and threadedly engaged with the guide block 34. When the motor 36 is started, the threaded rod 35 rotates, driving the guide block 34 to move up and down along the guide groove 311, thereby driving the bridge frame 32 and the strip plates 33 to move up and down as a whole.

[0037] The conveying mechanism 2 includes a mounting frame 21 on which multiple parallel conveying rollers 22 are rotatably mounted. The conveying rollers 22 are driven to rotate by a power device 23 to achieve horizontal conveying of the glass. To cooperate with the lifting mechanism 3, the mounting frame 21 has multiple clearance gaps 211 corresponding to the position and width of the strip plate 33, so that the strip plate 33 can freely pass through the gaps between the conveying rollers 22 during the lifting process without interference.

[0038] In operation, the AGV 1 travels to the side of the conveying mechanism 2 and precisely positions itself, aligning the strip plate 33 with the clearance gap 211. Motor 36 drives the strip plate 33 upwards, so that its top is slightly below the upper surface of the conveying roller 22. The conveying mechanism 2 operates, transporting the tempered glass to the area of ​​the strip plate 33. During this process, the guide plate 37 located at the top of a particular strip plate 33 plays a centering role; its symmetrically arranged inclined section 371 guides the glass to automatically center, while the parallel section 372 ensures the glass smoothly enters the lifting position. Subsequently, motor 36 continues to drive the strip plate 33 upwards, completely lifting the glass away from the conveying roller 22, completing the lifting action. Throughout the process, the lifting mechanism 3 and the conveying mechanism 2 achieve seamless connection from glass transport to lifting through spatial clearance and timing coordination, resulting in a compact structure and reliable operation.

[0039] Reference Figures 1 to 9The transfer mechanism 4 includes a stabilizing frame 41 and a connecting frame 42. A sliding block 43 is fixedly connected to one end of the connecting frame 42, and a positioning plate 45 is fixedly connected to the other end of the connecting frame 42. A support strip 46 is provided on the positioning plate 45.

[0040] The stabilizing frame 41 is fixedly installed on the AGV vehicle 1. A rack 411 and a sliding rod 412 are fixedly installed on the stabilizing frame 41. A sliding block 43 is sleeved on the surface of the sliding rod 412. A second motor 44 is fixedly installed on the top of the sliding block 43. A gear 441 is fixedly connected to the output end of the second motor 44. The gear 441 meshes with the rack 411.

[0041] Two support bars 46 are symmetrically arranged. One end of the support bar 46 is fixedly connected to a rotating shaft 47. The rotating shaft 47 is rotatably mounted on the positioning plate 45. A coil spring 471 is sleeved on the surface of the rotating shaft 47. Both support bars 46 are provided with triggering inclined surfaces 461 on the side close to each other. The top of the support bar 46 is provided with a support plane 462.

[0042] In summary, the transfer mechanism 4 is responsible for smoothly transferring the raised tempered glass from the docking position to the top of the AGV vehicle 1, or performing the reverse transfer process. Its structural design emphasizes stability, adaptability, and space utilization efficiency.

[0043] The transfer mechanism 4 mainly includes components such as a stabilizing frame 41, a connecting frame 42, a sliding block 43, a positioning plate 45, and a support strip 46. The stabilizing frame 41 is fixedly installed on the body of the AGV vehicle 1, serving as the basic support for the entire transfer mechanism 4. A rack 411 and at least one optical axis sliding rod 412 are horizontally arranged on it, and the two are arranged in parallel to guide the movement trajectory of the sliding block 43.

[0044] The sliding block 43 is fitted onto the sliding rod 412 through its internal channel, allowing it to slide axially and ensuring linear accuracy and low friction during movement. A second motor 44 is mounted on top of the sliding block 43. The gear 441 on its output shaft meshes with a rack 411 fixed to the stabilizer 41, forming a rack and pinion transmission pair. When the second motor 44 operates, the gear 441 rotates and "walks" on the rack 411, thereby precisely driving the sliding block 43 and its connecting components to perform linear reciprocating motion along the sliding rod 412.

[0045] The connecting frame 42 serves as a connecting component, with one end fixed to the sliding block 43 and the other end extending horizontally above the load-bearing area of ​​the AGV vehicle 1, connecting to the positioning plate 45. Two sets of rotatable support units are symmetrically mounted on the positioning plate 45. The core of each support unit is a support strip 46, one end of which is rotatably connected to the positioning plate 45 via a rotating shaft 47. A coil spring 471 is fitted onto the rotating shaft 47, providing an elastic torque in its natural state to keep the top support plane 462 horizontal and to give it an inward tendency to converge.

[0046] The support strips 46 are designed for connection, with trigger ramps 461 positioned on one side of each other. When the lifting mechanism 3 lifts the glass upwards, the glass edge contacts the trigger ramps 461. Under the action of the ramps, the two support strips 46 are pushed outwards and rotate around the rotating shaft 47. At this time, the coil spring 471 is twisted and stores energy. When the bottom surface of the glass completely passes the trigger ramps 461, the pushing force on the support strips 46 disappears, the coil spring 471 releases its elasticity, and drives the support strips 46 to quickly rotate back to their original position, so that the bottom surface of the glass rests smoothly on the support planes 462 of the two support strips 46, completing the automatic connection. Afterwards, the motor 44 drives the entire support assembly, along with the glass, to move to the designated position on the AGV vehicle 1.

[0047] The transfer mechanism 4 has a robust structure and precise transmission. Through ingenious mechanical design, it automates and flexibly handles the glass transfer process, effectively preventing the glass from bumping or slipping during the transfer, thus ensuring the safety of the transfer and the integrity of the glass.

[0048] The working principle of this invention is as follows: When it is necessary to transfer tempered glass from the conveying mechanism 2 to the AGV vehicle 1, the AGV vehicle 1 moves to the side of the conveying mechanism 2, so that the bridge frame 32 and the strip plate 33 move to the bottom of the conveying roller 22. Then, the motor 36 drives the threaded rod 35 to rotate around its own axis. The threaded rod 35 rotates and drives the guide block 34 to move vertically upward synchronously along the guide groove 311. The bridge frame 32 and the strip plate 33 also move upward synchronously. The bridge frame 32 passes upward through the clearance gap 211, and the strip plate 33 moves to the area between two adjacent conveying rollers 22.

[0049] The power unit 23 drives the conveyor roller 22 to rotate around its own axis. While the conveyor roller 22 rotates, it conveys the tempered glass. During the movement of the tempered glass, the tempered glass first contacts the inclined section 371 of the guide plate 37. The guide plate 37 aligns and calibrates the position of the tempered glass. Under the guidance of the guide plate 37, the tempered glass passes through the parallel section 372 and falls to the top of the strip plate 33.

[0050] Afterwards, motor 36 drives threaded rod 35 to rotate around its own axis again, and strip plate 33 continues to move vertically upward. Strip plate 33 lifts tempered glass upward. During this process, tempered glass first contacts the triggering inclined surface 461 of support bar 46. Under the pressure of tempered glass, support bar 46 rotates upward around the axis of rotation 47. Coil spring 471 gradually tightens and the elastic force increases. When tempered glass separates from triggering inclined surface 461, the elastic force of coil spring 471 is released and drives support bar 46 back to the initial position. At this time, tempered glass falls to the top of support plane 462.

[0051] Afterwards, motor 1 36 drives threaded rod 35 to rotate in the opposite direction around its own axis, strip plate 33 moves vertically downward and returns to the bottom of conveyor roller 22, motor 2 44 drives gear 441 to rotate around its own axis, gear 441 rotates synchronously along the length direction of rack 411, during this process, sliding block 43 slides synchronously along sliding rod 412, connecting frame 42, positioning plate 45 and support strip 46 also move synchronously with sliding block 43, and the tempered glass on top of support strip 46 gradually moves to the top of AGV vehicle 1.

[0052] When it is necessary to transfer tempered glass from AGV vehicle 1 to conveyor mechanism 2, AGV vehicle 1 moves to the side of conveyor mechanism 2, so that bridge 32 and strip plate 33 move to the bottom of conveyor roller 22. Similarly, motor 2 44 drives support bar 46 and tempered glass as a whole to move from the top of AGV vehicle 1 to the top of conveyor roller 22.

[0053] Then, motor 36 drives threaded rod 35 to rotate around its own axis, strip plate 33 moves vertically upward, strip plate 33 lifts tempered glass upward, and tempered glass separates from the supporting plane 462 at the top of supporting strip 46.

[0054] Afterwards, motor 2 44 drives the support bar 46 through the bottom of the strip plate 33 and back to the top of the AGV vehicle 1. Motor 1 36 drives the strip plate 33 down to the initial position through the threaded rod 35. During this process, the tempered glass falls back to the top of the conveyor roller 22.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
