Description

Technical Field

[0001] This invention relates to the field of AGV transportation equipment technology, specifically to an AGV transport vehicle. Background Technology

[0002] AGV, also known as Automated Guided Vehicle, refers to a transport vehicle equipped with electromagnetic or optical automatic guidance devices. It can travel along a prescribed guidance path and has safety protection and various transfer functions. AGV transport vehicles are widely used in various fields, especially in the optoelectronic field, where they are often used to transport wafer carriers.

[0003] For example, CN118083007A discloses an AGV transport vehicle, including a transport vehicle. A support platform is fixedly installed on the top of the transport vehicle, and a support plate is fixedly installed on the top of the support platform. A top plate is rotatably connected to one end of the top of the transport vehicle. A pushing mechanism, including a push plate, is provided on the top of the support platform. A rectangular groove is formed on the other side of the top of the support platform. A flatbed cart is provided at the bottom of the rear of the transport vehicle. Sliding columns are fixedly installed on both sides of the top of the flatbed cart. A first connecting block is slidably connected to the top of each of the two sliding columns. Two second connecting blocks are fixedly installed at the rear of the transport vehicle. This invention, by setting up the flatbed cart, allows it to create an angle when the transport vehicle moves onto uneven surfaces. The rear of the transport vehicle is raised and lowered using structures such as rocker arms and pull plates, reducing the tilt angle of the transport vehicle on uneven surfaces.

[0004] Although the aforementioned AGV transport vehicles can transport goods, their turning flexibility is insufficient, resulting in low transport efficiency. Furthermore, it is difficult to monitor the horizontal stability of the vehicle body in real time during transport, leading to instability when transporting delicate goods. Additionally, the accuracy of positioning the loading and unloading of goods is also insufficient. Therefore, a new type of AGV transport vehicle is needed to address these problems. Summary of the Invention

[0005] The purpose of this invention is to provide an AGV transport vehicle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an AGV transport vehicle, comprising a protective outer shell for support, a power distribution shell disposed on the upper part of the protective outer shell, and a battery box disposed on the lower part of the protective outer shell. A three-color warning light is disposed on the upper end face of the power distribution shell. Two sets of linear slide rails are disposed on one side of the inner end face of the power distribution shell, and two sets of linear slide shafts are disposed on the other side of the inner end face of the power distribution shell. A lead screw module is disposed between the two sets of linear slide rails. A guide slide is disposed on the side of the lead screw module. Both the linear slide shafts and the linear slide rails are slidably engaged with the guide slide.

[0007] The transfer device is provided in two sets, and the two sets of transfer devices are respectively located at the front and rear of the inner end of the protective shell. The transfer device is used for transfer and steering.

[0008] The horizontal radar consists of four sets, which are respectively located at the four corners of the upper surface of the protective housing. The horizontal radar is used to ensure that the power distribution housing is in a horizontal state in real time.

[0009] A wafer feeding device is fixedly mounted on the upper end face of the guide slide. The wafer feeding device is used for feeding, positioning, and transferring / unloading wafers.

[0010] Preferably, the wafer feeding device includes a support base plate. Two sets of support plates are disposed near the center of the upper end face of the support base plate. Three sets of second photoelectric sensors are alternately arranged on the upper part of the support plates. Two sets of second synchronous belt modules are disposed near the interior of the side end face of the support base plate. A drive module for driving the two sets of second synchronous belt modules is disposed at the front of the lower end face of the support base plate. Two sets of first sliding cylinders are respectively disposed on the side of the upper end face of the support base plate. A guide slide is disposed at the output end of the first sliding cylinder on one side, and the output end of the first sliding cylinder on the other side... The upper end is provided with a guide clamp plate. Three sets of second photoelectric sensors are equidistantly arranged at the rear of the upper end face of the guide slide plate. A first photoelectric sensor is arranged at the middle of the upper end face of the guide slide plate. A fixed slide rail is arranged at the middle of the upper end face of the support base plate. A traction device is slidably arranged on the upper end face of the fixed slide rail. A first synchronous belt module for driving the traction device is arranged near the middle of the upper end face of the support base plate. A guide card seat is arranged on the upper part of the two sets of second synchronous belt modules. A protective card frame is arranged on the upper part of the guide card seat. Wafer carriers are equidistantly arranged on the inner end face of the guide card seat.

[0011] Preferably, the traction device includes a positioning slide, a second slide cylinder is provided at the middle of the upper end face of the positioning slide, and a cylinder guide is provided at the output end of the second slide cylinder. Two sets of guide rollers are provided on the front end face of the cylinder guide, two sets of positioning slide rails are provided on the front end face of the positioning slide, and linear sliders are slidably engaged on the front end face of both sets of positioning slide rails. Positioning plates are provided on the front end face of the two sets of linear sliders, and wedge-shaped guide blocks for guidance are provided on the lower end face of the positioning plates.

[0012] Preferably, the transfer device includes a support guide seat, three sets of buffer pads are symmetrically and equidistantly arranged on the upper end face of the support guide seat, and a support guide shaft is arranged on the upper end face of the buffer pads. Two sets of reducers are staggered on the inner end face of the support guide seat, a stepper motor is arranged at the input end of the reducer, and an ohmic wheel is arranged at the output end of the reducer.

[0013] Preferably, two sets of second synchronous belt modules drive the guide card seat to slide back and forth on the upper part of the support base plate, and three sets of staggered second photoelectric sensors perform real-time positioning detection of the guide card seat. The three sets of second photoelectric sensors can perform multiple positioning of the guide card seat through multiple preset points on the bottom of the guide card seat, which effectively improves the accuracy of subsequent material feeding positioning.

[0014] Preferably, the first slide cylinder drives the guide slide plate to guide the side of the guide plate seat, and the first slide cylinder on the other side limits the guide plate seat through the guide clamp plate. The guide clamp plate is provided with a limit hook block inside, which facilitates the limiting of the side of the guide plate seat and improves the accuracy of lateral pushing and positioning.

[0015] Preferably, a traction groove is provided at the bottom of the guide plate near the front. The second slide cylinder is adapted to the traction groove through the positioning plate, thereby driving the guide plate to move on the upper part of the support base plate. The traction groove can provide sufficient limiting foundation for the positioning plate to be inserted, so that the positioning plate can rigidly limit the bottom of the guide plate through the traction groove, thereby improving the stability of subsequent traction guidance.

[0016] Preferably, the second slide cylinder drives the wedge-shaped guide block and the positioning plate to lift synchronously through the cylinder guide seat. When unloading the wafer carrier, the cylinder guide seat moves forward under the drive of the second slide cylinder, which facilitates the traction operation of the cylinder guide seat driving the positioning plate to the bottom of the guide plate through the wedge-shaped guide block. This allows the guide plate to move stably under the drive of the positioning plate. The rigid limiting and guiding can effectively improve the stability of the guide plate's movement and facilitate subsequent unloading and docking.

[0018] 1. By setting up a transfer device, the present invention provides four sets of ohmic wheels inside the protective shell, each with an independent drive system. This allows the AGV to move and turn in various directions through various speed differences under the independent drive of the four sets of ohmic wheels, effectively improving the adaptability of the AGV to transport wafer trays.

[0019] 2. By setting up horizontal radar, the present invention enables four sets of horizontal radars to detect the horizontal status of the AGV in real time when transporting precision workpieces, preventing the precision workpieces inside from changing their transport status and improving the stability of AGV transportation.

[0020] 3. By setting up a transfer device and using multiple positioning detections by the first photoelectric sensor, the second photoelectric sensor, and the second photoelectric sensor, this invention can effectively improve the accuracy and automated transmission of the material guide card's loading and unloading positioning on the upper part of the support base plate. At the same time, the traction device and the second synchronous belt module can also improve the automation and convenience of loading and unloading the material guide card and wafer carrier.

Wafer carriers 28 are equidistantly arranged on the inner end face of the guide card holder 27.

[0043] like Figure 7 , Figure 8 and Figure 9 The traction device 22 includes a positioning slide 223. A second slide cylinder 224 is provided at the middle of the upper end face of the positioning slide 223. A cylinder guide 227 is provided at the output end of the second slide cylinder 224. Two sets of guide rollers 228 are provided on the front end face of the cylinder guide 227. Two sets of positioning slide rails 225 are provided on the front end face of the positioning slide 223. Linear sliders 222 are slidably engaged on the front end face of both sets of positioning slide rails 225. Positioning plates 221 are provided on the front end face of the two sets of linear sliders 222. A wedge-shaped guide block 226 for guidance is provided on the lower end face of the positioning plates 221.

[0044] like Figure 10 and Figure 11 The transfer device 3 includes a support guide 32. Three sets of buffer pads 33 are symmetrically and equidistantly arranged on the upper end face of the support guide 32. A support guide shaft 31 is arranged on the upper end face of the buffer pads 33. Two sets of reducers 36 are staggered on the inner end face of the support guide 32. A stepper motor 35 is arranged at the input end of the reducer 36, and an ohmic wheel 34 is arranged at the output end of the reducer 36.

[0045] like Figure 4Two sets of second synchronous belt modules 24 drive the guide plate 27 to slide back and forth on the upper part of the support base plate 215. Three sets of staggered second photoelectric sensors 216 perform real-time positioning detection on the guide plate 27. The three sets of second photoelectric sensors 216 can perform multiple positioning of the guide plate 27 through multiple preset points on the bottom of the guide plate 27, which effectively improves the accuracy of subsequent material feeding positioning.

[0046] like Figure 4 The first slide cylinder 213 drives the guide slide plate 211 to guide the side of the guide plate 27. The first slide cylinder 213 on the other side limits the guide plate 27 through the guide clamp plate 25. The two sets of first slide cylinders 213 can adjust the guide plate 27 laterally through the guide slide plate 211 and the guide clamp plate 25. The two sets of second synchronous belt modules 24 can adjust the guide plate 27 longitudinally, so that the preset point at the bottom of the guide plate 27 can be positioned on the upper part of the second photoelectric sensor 216, improving the positioning accuracy. At the same time, the guide clamp plate 25 is provided with a limit hook block inside, which can limit the side of the guide plate 27 and improve the accuracy of lateral pushing and positioning.

[0047] like Figure 6 The bottom of the guide plate 27 is provided with a traction groove near the front. The second slide cylinder 224 is adapted to the traction groove through the positioning plate 221, thereby driving the guide plate 27 to move on the upper part of the support base plate 215. The traction groove can provide sufficient limiting foundation for the positioning plate 221 to be inserted, so that the positioning plate 221 can rigidly limit the bottom of the guide plate 27 through the traction groove, thereby improving the stability of subsequent traction guidance.

[0048] like Figure 7 and Figure 8 The second slide cylinder 224 drives the wedge-shaped guide block 226 and the positioning plate 221 to lift synchronously through the cylinder guide seat 227. When unloading the wafer carrier 28, the cylinder guide seat 227 moves forward under the drive of the second slide cylinder 224, which facilitates the traction operation of the cylinder guide seat 227 driving the positioning plate 221 to the bottom of the guide plate 27 through the wedge-shaped guide block 226. This allows the guide plate 27 to move stably under the drive of the positioning plate 221. The rigid limiting and guiding can effectively improve the stability of the displacement of the guide plate 27 and facilitate subsequent unloading and docking.

[0049] Working Principle: Before use, if the wafer carrier 28 needs to be transferred and transported, the power distribution and control module inside the power distribution housing 1 can start two sets of stepper motors 35. The battery box 4 can provide power to the two sets of stepper motors 35. Then, the two sets of stepper motors 35 can drive the two sets of ohmic wheels 34 to rotate through the torque increase of the reducer 36. Since the bottom of the protective housing 5 is independently driven by four sets of ohmic wheels 34, the four sets of ohmic wheels 34 can rotate and displace at any angle through the speed difference, thereby improving the convenience and stability of the subsequent transportation of the wafer carrier 28. At the same time, when transporting the wafer carrier 28, the four sets of horizontal radars 6 located on the upper part of the protective housing 5... It can detect the level of the vehicle body in real time, thereby improving the stability of transporting the wafer carrier 28. When loading the wafer carrier 28, the lead screw module 10 can drive the wafer guiding device 2 to adjust to a suitable height through the guide slide 7. Then, the external feeding module can synchronously guide the guide card 27 and the wafer carrier 28 to the upper part of the two sets of second synchronous belt modules 24. At this time, the drive module 210 is started, and the drive module 210 can synchronously drive the two sets of second synchronous belt modules 24 to rotate, so that the two sets of second synchronous belt modules 24 can drive the guide card 27 and the wafer carrier 28 to move back and forth on the support base plate 215. The multiple sets of second photoelectric sensors 216 arranged in an alternating manner can... The bottom of the guide plate 27 is detected and positioned in real time. When the guide plate 27 moves down in the reciprocating motion of the second synchronous belt module 24 and is longitudinally positioned to the preset position, the first slide cylinder 213 on one side can drive the guide clamp 25 to move inward. The guide clamp 25 is used to limit the side of the guide plate 27. At the same time, the first slide cylinder 213 on the other side can drive the guide slide plate 211 to guide the guide plate 27. The first photoelectric sensor 212 and the second photoelectric sensor 214 can detect and position the side of the guide plate 27 until the lateral and longitudinal positions of the guide plate 27 are aligned with the second photoelectric sensor 216, thus completing the loading and positioning operation. When the guide holder 27 and the wafer carrier 28 are unloaded, the second slide cylinder 224 can drive the cylinder guide 227 to move forward, so that the cylinder guide 227 can drive the wedge guide block 226 to rise through the guide roller 228. Then the wedge guide block 226 can be moved upward and limited to the traction groove at the bottom of the guide holder 27 through the positioning plate 221. Then the first synchronous belt module 23 is started, and the first synchronous belt module 23 can drive the traction device 22 to move forward as a whole. At the same time, the two sets of second synchronous belt modules 24 can assist the guide holder 27 to move forward until the guide holder 27 and the wafer carrier 28 are displaced to the external unloading position. At this time, the traction device 22 retracts and resets under the drive of the first synchronous belt module 23.
