Description

Technical Field

[0001] The present invention belongs to the technical field of mobile automatic charging and discharging in a vacuum environment, and specifically relates to a movable automatic charging and discharging system. Background Art

[0002] During actual use, when the automatic charging and discharging system equipment moves to the preliminary position, the interfaces of the charging and discharging components are not necessarily corresponding to the designated interfaces at this time, and fine-tuning by the operator is required. However, since the equipment is installed on the flatbed trailer chassis, fine-tuning in the direction is not convenient, which is not conducive to improving the use efficiency. Moreover, during the use of the equipment, the entire flatbed trailer chassis needs to be lifted separately to ensure stability. Therefore, the overall operation is relatively complex and not conducive to improving efficiency.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

The return frame is connected to the side wall of the synchronous plate, and the return frame slides outside the guide roller;

[0009] The charging and exhausting assembly is installed on the carrier table.

[0010] As a preferred embodiment of the present invention, a pull rod is installed on the side wall of the frame frame. The pull rod is triangular, and an installation ring is welded at the end of the pull rod. A support leg is installed at the corner of the frame frame. The length of the support leg is less than the length of the lifting arm, and rollers are installed at the end of the support leg.

[0011] As a preferred embodiment of the present invention, a positioning bracket is installed on the outer shell of the dual-axis stepper motor. The positioning bracket is welded at the bottom of the substrate. A connecting seat is installed on the output shaft of the dual-axis stepper motor. The connecting seat is welded at the bottom of the substrate.

[0012] As a preferred embodiment of the present invention, a guiding slider is installed on the synchronous plate. The guiding slider slides on the surface of the lifting slot. The distance between the transposition slot and the outer shell of the dual-axis stepper motor is greater than the distance between the lifting slot and the outer shell of the dual-axis stepper motor, and the connection between the transposition slot and the lifting slot is chamfered.

[0013] As a preferred embodiment of the present invention, a pair of sliding plates are symmetrically installed on the fixed block. A limiting rod is movably installed through each pair of sliding plates. Limiting seats are installed at both ends of the limiting rod. The limiting seats are welded at the bottom of the substrate. A limiting spring is sleeved on the limiting rod. One end of the limiting spring is clamped on the limiting seat, and the other end is clamped on the side wall of the sliding plate.

[0014] As a preferred embodiment of the present invention, guiding wheels are installed at the end of each pair of lifting arms. The guiding wheels are placed at the bottom of the substrate. A synchronous shaft is installed at the rotation center of several pairs of lifting arms.

The lifting groove on the guiding roller can drive the synchronizing plate to slide horizontally. The synchronizing plate can drive the fixed block and the insertion rod to slide. The insertion rod pushes the rocker arm to swing, and the rocker arm drives the coaxial lifting arm to rotate downward. Finally, the entire device can be lifted as a whole to ensure the stability of the device. And during the sliding process of the synchronizing plate, the looped frame and the synchronizing rod on the synchronizing plate slide horizontally. Finally, the synchronizing rod can slide from the unlocking groove to the circular ring groove, thereby unlocking the carrier platform on which the charging and discharging assembly is installed. At this time, as the guiding roller continues to rotate, the rotating semi-gear and the positioning gear ring are engaged, driving the carrier platform on which the positioning gear ring is installed to rotate. Finally, the purpose of adjusting the direction of the charging and discharging assembly can be achieved. The present invention uses one driving source to lift the device as a whole to ensure the stability of the device. And during the lifting process of the device, the synchronizing rod slides in the unlocking groove, and can gradually unlock the charging and discharging assembly that needs to be rotated. After the unlocking is completed and the lifting is completed, the driving source can also adjust the direction of the charging and discharging assembly. The overall operation is relatively simple, which is convenient for improving the use efficiency.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0038] Embodiment 1: As shown in Figures 1 to 9As shown in the figure, a movable automatic charging and discharging system includes a support unit 100, a lifting unit 200, a commutation unit 300, and a charging and discharging assembly 400; the support unit 100 includes a vehicle frame 101, and a base plate 1011 is installed at the center of the vehicle frame 101 through bolts;

[0039] The lifting unit 200 includes a double-shaft stepper motor 201. Guide rollers 202 are installed on the output shafts on both sides of the double-shaft stepper motor 201. Combination grooves are provided on the guide rollers 202, and the combination grooves include a lifting groove 2021 and a commutation groove 2022. The lifting groove 2021 and the commutation groove 2022 are connected end to end. The lifting groove 2021 is a spiral groove, and the commutation groove 2022 is an annular groove. A synchronous plate 203 is slidably installed on the lifting groove 2021. A connecting block 2032 is installed at the end of the synchronous plate 203. A fixing block 204 is installed on the connecting block 2032. A plug rod 205 is installed on the side wall of the fixing block 204. A number of pairs of lifting arms 206 are rotatably installed at the bottom of the vehicle frame 101, and a number of pairs of lifting arms 206 are in an inclined state. The rotation centers of a number of pairs of lifting arms 206 are on the same straight line, and a rocker arm 2052 is installed on the rotation center. The rocker arm 2052 is movably inserted with the plug rod 205; by driving the guide roller 202 at the end to rotate through the double-shaft stepper motor 201, the lifting groove 2021 on the guide roller 202 can guide the horizontal sliding of the synchronous plate 203. The synchronous plate 203 can drive the fixing block 204 and the plug rod 205 to slide. The plug rod 205 pushes the rocker arm 2052 to swing. The rocker arm 2052 drives the coaxial lifting arm 206 to rotate downward. The lifting arm 206 presses against the ground, and finally the entire device can be lifted as a whole to ensure the stability of the device;

[0040] The commutation unit 300 includes a carrier 301. A pair of unlocking grooves 303 are symmetrically formed at the bottom of the carrier 301. At the end of each of the pair of unlocking grooves 303, a circular groove 3031 is communicated. The circular groove 3031 is formed at the bottom of the carrier 301. A synchronous rod 3021 is slidably mounted on the unlocking groove 303. A return frame 302 is mounted at the bottom of the synchronous rod 3021. The return frame 302 is connected to the side wall of the synchronous plate 203. The return frame 302 slides outside the guide roller 202. During the horizontal sliding of the synchronous plate 203, the return frame 302 and the synchronous rod 3021 on the synchronous plate 203 slide horizontally. Finally, the synchronous rod 3021 can slide from the unlocking groove 303 into the circular groove 3031, thereby unlocking the carrier 301 on which the air charging and discharging assembly 400 is installed. The carrier 301 is rotatably mounted on the substrate 1011. A positioning gear ring 3012 is mounted at the bottom of the carrier 301. The positioning gear ring 3012 is adapted to a semi-gear 3013 mounted on the side wall of the guide roller 202. The central angle corresponding to the semi-gear 3013 is the same as the central angle corresponding to the transposition groove 2022. When the guide roller 202 drives the synchronous plate 203 to move to the transposition groove 2022, at this time, the lifting arm 206 stops moving, and the synchronous rod 3021 in the unlocking groove 303 is unlocked synchronously. As the guide roller 202 continues to rotate, at this time, the semi-gear 3013 and the positioning gear ring 3012 are engaged, driving the positioning gear ring 3012 to rotate, thereby driving the entire carrier 301 to rotate, achieving the purpose of adjusting the direction.

[0041] The air charging and discharging assembly 400 is installed on the carrier 301. The air charging and discharging assembly 400 is a prior art, and its working principle will not be elaborated here.

[0042] As Figures 1 to 9 shown, in the specific implementation manner, a pull rod 102 is mounted on the side wall of the frame frame 101. The pull rod 102 is triangular, and an installation ring 1021 is welded at the end of the pull rod 102. It is convenient to connect with other structures through the installation ring 1021. Support legs 103 are mounted at the corners of the frame frame 101. The length of the support legs 103 is less than the length of the lifting arm 206. Rollers 1031 are mounted at the ends of the support legs 103. It is convenient to move the entire structure later through the rollers 1031.

[0043] Embodiment 2: Different from Embodiment 1 and this embodiment: As Figures 1 to 9As shown, a positioning bracket 2011 is installed on the housing of the biaxial stepper motor 201, and the positioning bracket 2011 is in a mountain shape. The positioning bracket 2011 is welded to the bottom of the substrate 1011. The positioning bracket 2011 serves the purpose of positioning. A connecting seat 2012 is installed on the output shaft of the biaxial stepper motor 201, and the connecting seat 2012 is welded to the bottom of the substrate 1011. The operator can drive the guide roller 202 to rotate on both sides of the connecting seat 2012 through the biaxial stepper motor 201.

[0044] As Figures 1 to 9 shown, in the specific implementation, a guide slider 2031 is installed on the synchronization plate 203. The guide slider 2031 is slidably arranged on the surface of the lifting groove 2021. The distance between the transposition groove 2022 and the housing of the biaxial stepper motor 201 is greater than the distance between the lifting groove 2021 and the housing of the biaxial stepper motor 201, and the connection between the transposition groove 2022 and the lifting groove 2021 is chamfered.

[0045] As Figures 1 to 9 shown, further, a pair of sliding plates 2041 are symmetrically installed on the fixed block 204. A limiting rod 2042 is movably installed through each pair of sliding plates 2041. Limiting seats 2043 are installed at both ends of the limiting rod 2042. The limiting seats 2043 are welded to the bottom of the substrate 1011. A limiting spring 2044 is sleeved on the limiting rod 2042. One end of the limiting spring 2044 is clamped on the limiting seat 2043, and the other end is clamped on the side wall of the sliding plate 2041. During the horizontal sliding of the guide slider 2031, the synchronization plate 203 on the side wall of the guide slider 2031 slides horizontally synchronously. At this time, the connecting block 2032 on the synchronization plate 203 drives the fixed block 204 to slide horizontally. The sliding plates 2041 on the fixed block 204 slide synchronously. The sliding plates 2041 slide on the surface of the limiting rod 2042 at this time, and the length of the sliding plates 2041 from the side wall of the limiting seat 2043 changes, thereby compressing the limiting spring 2044 between the two. It is convenient for the later reset operation through the limiting spring 2044.

[0046] As Figures 1 to 9As shown in the figure, further, a guide wheel 2061 is installed at the end of each pair of lifting arms 206. The guide wheel 2061 is oval-shaped and is placed at the bottom of the base plate 1011. A synchronous shaft 2062 is installed on the rotation centers of several pairs of lifting arms 206. Both ends of the synchronous shaft 2062 are rotatably connected to the inner side wall of the vehicle frame 101, and the rotation center of the synchronous shaft 2062 is connected to that of the rocker arm 2052. A strip-shaped groove 2053 is formed on the surface of the rocker arm 2052. The insertion rods 205 are placed on both sides of the rocker arm 2052, and a sliding rod 2051 is installed on the insertion rod 205. The sliding rod 2051 is slidably arranged in the strip-shaped groove 2053, and the width of the strip-shaped groove 2053 is adapted to the diameter of the sliding rod 2051. When the fixed block 204 slides, at this time, the insertion rods 205 on the side wall of the fixed block 204 slide on both sides of the rocker arm 2052, and the sliding rod 2051 on the insertion rod 205 slides on the side wall of the strip-shaped groove 2053 of the rocker arm 2052 at this time. Finally, the rocker arm 2052 can be pushed to swing. The synchronous shaft 2062 on the rocker arm 2052 can rotate on the vehicle frame 101 at this time. The synchronous shaft 2062 can drive the lifting arm 206 to rotate downward at this time. The lifting arm 206 presses against the ground, thereby lifting the entire device, thus ensuring the overall stability of the device.

[0047] Embodiment 3: The difference between this embodiment and Embodiment 2 is as follows: As Figures 1 to 9 shown in the figure, a guide ring 3011 is installed at the bottom of the bearing platform 301. The guide ring 3011 rotatably penetrates the base plate 1011. The bottom of the guide ring 3011 is connected to the positioning gear ring 3012. One-fourth of the number of teeth of the positioning gear ring 3012 is the same as the number of teeth on the half gear 3013. A positioning shaft 3014 is installed at the center position of the bottom of the bearing platform 301. The bottom of the positioning shaft 3014 is rotatably connected to the base plate 1011. As the guide roller 202 rotates, the half gear 3013 on the side wall of the guide roller 202 drives the positioning gear ring 3012 to rotate. Then, the guide ring 3011 connected to the positioning gear ring 3012 rotates at this time. The guide ring 3011 drives the bearing platform 301 to rotate. The bearing platform 301 rotates on the positioning shaft 3014, and the angle of the air charging and discharging assembly 400 installed on the bearing platform 301 changes, thereby achieving the purpose of adjusting the position of the air charging and discharging assembly 400.

[0048] As Figures 1 to 9 shown in the figure, in the specific implementation manner, a through groove 3023 is formed on the base plate 1011. The through groove 3023 and the unlocking groove 303 are in the same plane, and the specifications of the unlocking groove 303 and the through groove 3023 are adapted to each other. The synchronous rod 3021 movably penetrates the through groove 3023. A guide rod 3022 is movably penetrated and installed inside the synchronous rod 3021. Both ends of the guide rod 3022 are respectively connected to the side wall of the through groove 3023. The connected synchronous rod 3021 can only slide horizontally through the guide rod 3022 and the through groove 3023.

[0049] The implementation principle of a movable automatic charging and discharging system of the present invention is as follows:

[0050] When the device moves to the approximate position, the operator first starts the dual-axis stepper motor 201. The dual-axis stepper motor 201 drives the guide rollers 202 on both sides to rotate on both sides of the connecting seat 2012. A combined groove is provided on the connecting seat 2012. At this time, the lifting groove 2021 and the transposition groove 2022 in the combined groove rotate synchronously. When the lifting groove 2021 rotates, the lifting groove 2021 can drive the guide slider 2031 to slide horizontally. When the guide slider 2031 slides to the surface of the transposition groove 2022, the half gear 3013 on the guide roller 202 just meshes with the positioning gear ring 3012 at this time.

[0051] During the horizontal sliding of the guide slider 2031, the synchronous plate 203 on the side wall of the guide slider 2031 slides horizontally synchronously. At this time, the connecting block 2032 on the synchronous plate 203 drives the fixed block 204 to slide horizontally, and the sliding plate 2041 on the fixed block 204 slides synchronously. The sliding plate 2041 slides on the surface of the limiting rod 2042 at this time, and the length of the sliding plate 2041 from the side wall of the limiting seat 2043 changes, thereby compressing the limiting spring 2044 between the two, which facilitates the later reset operation through the limiting spring 2044.

[0052] When the fixed block 204 slides, the insertion rod 205 on the side wall of the fixed block 204 slides on both sides of the rocker arm 2052, and the sliding rod 2051 on the insertion rod 205 slides on the side wall of the strip-shaped groove 2053 of the rocker arm 2052 at this time, and finally can push the rocker arm 2052 to swing. The synchronous shaft 2062 on the rocker arm 2052 can rotate on the vehicle frame 101 at this time, and the synchronous shaft 2062 can drive the lifting arm 206 to rotate downward at this time. The lifting arm 206 presses against the ground, thereby lifting the entire device and ensuring the overall stability of the device.

[0053] During the horizontal sliding of the synchronous plate 203, the return frame 302 on the synchronous plate 203 slides on the side wall of the guide roller 202, and the synchronous rod 3021 on the return frame 302 slides in the through groove 3023 at this time. The synchronous rod 3021 slides along the penetrated guide rod 3022 to achieve the purpose of guiding. The top of the synchronous rod 3021 finally slides along the unlocking groove 303 and finally can slide into the circular ring groove 3031, that is, the limit of the bearing platform 301 is unlocked.

[0054] When the guiding slider 2031 slides into the transposition groove 2022, the half gear 3013 and the positioning gear ring 3012 are engaged at this time. As the guiding roller 202 continues to rotate, the above-mentioned jacking and unlocking operations stop synchronously. However, with the rotation of the guiding roller 202, the half gear 3013 on the side wall of the guiding roller 202 drives the positioning gear ring 3012 to rotate. Furthermore, the guiding ring 3011 connected to the positioning gear ring 3012 rotates at this time, and the guiding ring 3011 drives the bearing platform 301 to rotate. The bearing platform 301 rotates on the positioning shaft 3014, and the angle of the air charging and discharging assembly 400 installed on the bearing platform 301 changes, thus achieving the purpose of adjusting the position of the air charging and discharging assembly 400.

[0055] The operator starts the air charging and discharging assembly 400 at this time. The air charging and discharging assembly 400 is a prior art, and its working principle will not be elaborated here.
