[0052] A preparation process for a cabin upper bracket production device comprises the following steps:

[0053] S1. Loading:

[0054] S11. Debugging:

[0055] With the help of an overhead crane, the bundled aluminum profiles with packaging bags entering the factory are lifted and transferred to the bundle placement platform. One side of the bundled aluminum profile is fitted with the baffle. The horizontal linear module of the bag breaking and feeding device is opened to drive the cutter to move horizontally until the cutter is aligned with the gap between two adjacent aluminum profiles, and then the debugging is stopped.

[0056] S12, broken bag:

[0057] With the help of an overhead crane, the bundled aluminum profiles with packaging bags entering the factory are lifted and transported to the bundle placement platform. At this time, the laser emitted by the first laser sensor is blocked and then reflected. After receiving the reflected laser signal, the first laser sensor transmits the signal to the controller. The controller turns on the first longitudinal linear module and the first cylinder of the bag breaking and feeding device. The first cylinder of the bag breaking and feeding device drives the cutting knife to move downward a set distance. At the same time, the first longitudinal linear module drives the cutting knife to move toward the bundled aluminum profile through the first cylinder until the cutting knife extends into the gap between the two aluminum profiles and continues to move along the gap. The packaging bags at the gap are separated by the cutting knife, and the bundled aluminum profile loses the restraint of the packaging bag and spreads out, rolling down along the inclined unloading platform.

[0058] S13, material division:

[0059] The aluminum profiles roll down onto the material distribution platform, and the material distribution wheel rotates under the action of the material distribution drive motor. At this time, the material distribution plate outside the material distribution wheel transfers multiple aluminum profiles in sequence to the side of the material distribution platform away from the inclined unloading platform;

[0060] In this process, since the length of the longitudinally placed aluminum profile is less than the distance between the toggle plate and the material distribution platform, it touches the bottom end of the toggle plate and is changed from longitudinal placement to transverse placement under the action of the toggle plate;

[0061] S2, cutting and punching:

[0062] After receiving the signal from the aluminum profile passing through the material distribution wheel, the infrared receiver sends a signal to the cutting and punching device. First, the transfer unit of the cutting and punching device starts to move, and the swing drive motor drives the swing connecting rod to rotate, and the swing connecting rod drives the swing plate to swing back and forth. In this process, the aluminum profile on the material distribution platform is transferred to the bearing assembly with the help of the transfer positioning frame until the pressure sensors in multiple bearing assemblies collect pressure signals, and then the material distribution drive motor and the swing drive motor are turned off. At the same time, the push clamping unit is opened, and the second longitudinal linear module drives the rotating chuck to move toward the bearing unit until the rotating chuck is crimped with the end of the aluminum profile, triggering the limit switch. The limit switch opens the rotating chuck, and clamps one end of the aluminum profile with the help of the rotating chuck. Under the action of the second longitudinal linear module, the rotating chuck moves forward and rotates until the other end of the aluminum profile is aligned with the laser cutting unit. At this time, the third laser sensor collects the aluminum profile in place signal and transmits this signal to the controller. The controller turns on the laser cutting unit, uses the built-in program of the laser cutting unit to punch the aluminum profile, and cuts off the aluminum profile after the set length. The cut aluminum profile falls onto the transmission roller group of the burr removal device;

[0063] S3. Deburring:

[0064] After the fourth laser sensor collects the signal that the aluminum profile is in place, the abrasive impact unit is turned on. First, the second cylinder drives the synchronous lower pressure plate to move downward a set distance. At this time, the nozzle is aligned with one end of the aluminum profile, and then the second cylinder is closed, and the third longitudinal linear module is opened. The third longitudinal linear module drives the nozzle to move in the direction of the aluminum profile until the nozzle is inserted into the aluminum profile. After the piezoelectric switch on the nozzle senses the insertion signal, the third longitudinal linear module is closed, the normally closed contactor is triggered, the normally closed contactor is opened, the annular electromagnet loses power, and the second lower pressure plate presses the surface of the aluminum profile under the action of the first compression spring. Then, the slurry pump is turned on to extract the abrasive stored in the abrasive storage box and spray it into the interior of the aluminum profile through the nozzle. The burrs are removed by the friction between the abrasive and the aluminum profile. The abrasive containing burrs falls back into the abrasive storage box under the action of gravity, and is sprayed into the interior of the aluminum profile again along the feeding pipe and the nozzle after being filtered by the burr filtering component. After the delay setting time, the normally closed contactor is closed, the annular electromagnet is energized, and the magnetic force is generated by magnetoelectricity to re-adsorb the second lower pressure plate, relieve the pressure on the outside of the aluminum profile, and at the same time, the slurry pump is turned off, and the abrasive impact unit is reset to prepare for the next deburring.

[0065] S4. Welding:

[0066] The staff takes out the aluminum profile after the burrs are removed, and places it under the first clamping assembly when the aluminum profile is a side beam, and places it under the second clamping assembly when the aluminum profile is a connecting beam, until the upper bracket of the cabin is formed; open the first clamping assembly and the second clamping assembly on the welding device, wherein the synchronous drive motor of the first clamping assembly drives the bottom rotating section to rotate through the synchronous transmission chain and the synchronous transmission sprocket, and the bottom rotating section drives the coaxially connected top threaded section to rotate, and with the cooperation of the thread inside the guide column, the top threaded section shrinks into the bottom rotating section, driving the horizontal longitudinal pressure rod to rotate toward the direction of the side beam and descend at the same time, until the horizontal longitudinal pressure rod presses the top of the side beam; at the same time, the third cylinder of the second clamping assembly extends, driving one end of the lever to rotate upward, and under the action of the support, the other end of the lever rotates downward until the horizontal transverse pressure rod presses the top of the connecting beam;

[0067] Then the fourth cylinder is turned on, and the fourth cylinder drives the top swing platform to rotate toward the welding robot until it reaches a set distance and then closes. At this time, the top swing platform tilts toward the welding robot, and then the welding robot is turned on for front welding;

[0068] After the front welding is completed, turn off the welding device, take out the upper bracket of the cabin, and put it back on the top swing platform with the back facing up, and start the welding device again. Similarly, weld the back of the upper bracket of the cabin;

[0069] S5. Transshipment:

[0070] Turn on the vacuum adsorption transfer device, and the fourth longitudinal linear module drives the vacuum adsorption unit above the welding device to move until the second laser sensor on the top swing platform detects a signal in place, and turns on the sixth cylinder and the vacuum pump. The sixth cylinder drives the transfer plate and the suction head downward until the upper bracket of the cabin is adsorbed. The vacuum adsorption transfer device runs in the reverse direction, driving the upper bracket of the cabin to move toward the shaping device until the second laser sensor on the top of the shaping platform detects a signal in place, and the vacuum adsorption transfer device places the upper bracket of the cabin between the two shaping units of the shaping platform;

[0071] S6, Plastic surgery:

[0072] The shaping unit is opened, and the fifth cylinder drives the trapezoidal block to extend. Under the action of the bevel, the shaping block is driven to move toward the side crossbeam of the upper bracket of the cabin, and the end of the upper bracket of the cabin is squeezed and shaped;

[0073] S7. After the shaping is completed, the vacuum adsorption transfer device is opened again, and the vacuum adsorption unit above the shaping unit takes out the shaped upper bracket of the cabin, and at the same time, the vacuum adsorption unit above the welding device transfers the next upper bracket of the cabin to be shaped to the shaping platform.

[0074] The present invention has the following beneficial effects:

[0075] 1. By setting up a feeding device, the bundled aluminum profiles can be opened mechanically, which improves processing efficiency and reduces labor intensity;

[0076] 2. The layout of the production line only requires one staff member to operate, which reduces labor costs and improves production efficiency.

No improvement is made to them. The principle of controlling the running direction of the motor and the cylinder through sensors is common knowledge in the field, so it will not be elaborated here.

[0116] A preparation process of a cabin upper bracket 9 production device comprises the following steps:

[0117] S1. Loading:

[0118] S11. Debugging:

[0119] The bundled aluminum profiles 1 with packaging bags entering the factory are lifted and transferred to the bundle placement platform 22 by means of an overhead crane. One side of the bundled aluminum profiles 1 is fitted with the baffle 221. The transverse linear module 241 of the bag breaking and feeding device 2 is opened to drive the cutting knife 244 to move transversely until the cutting knife 244 is aligned with the gap between two adjacent aluminum profiles, and the debugging is stopped.

[0120] S12, broken bag:

[0121] With the help of an overhead crane, the bundled aluminum profiles 1 with packaging bags entering the factory are lifted and transported to the bundle placement platform 22. At this time, the laser emitted by the first laser sensor is blocked and then reflected. After receiving the reflected laser signal, the first laser sensor transmits the signal to the controller, and the controller turns on the first longitudinal linear module 242 and the first cylinder 243 of the bag breaking and feeding device 2. The first cylinder 243 of the bag breaking and feeding device 2 drives the cutter 244 to move downward by a set distance. At the same time, the first longitudinal linear module 242 drives the cutter 244 to move toward the bundled aluminum profile 1 through the first cylinder 243, until the cutter 244 extends into the gap between the two aluminum profiles and continues to move along the gap. The packaging bags at the gap are separated by the cutter 244, and the bundled aluminum profiles 1 lose the restraint of the packaging bags and spread out, and roll down along the inclined unloading platform 23;

[0122] S13, material division:

[0123] The aluminum profiles roll onto the material distribution platform 21, and the material distribution wheel 211 rotates under the action of the material distribution drive motor. At this time, the material distribution plate outside the material distribution wheel 211 sequentially transfers multiple aluminum profiles to the side of the material distribution platform 21 away from the inclined unloading platform 23;

[0124] In this process, since the length of the longitudinally placed aluminum profile is less than the distance between the toggle plate 212 and the material distribution platform 21, it touches the bottom end of the toggle plate 212 and is changed from longitudinal placement to transverse placement under the action of the toggle plate 212;

[0125] S2, cutting and punching:

[0126] After receiving the signal from the infrared receiver, the infrared receiver sends a signal to the cutting and punching device 3 after the aluminum profile passes through the material distribution wheel 211. First, the transfer unit 33 of the cutting and punching device 3 starts to move, and the swing drive motor drives the swing connecting rod 333 to rotate, and the swing connecting rod 333 drives the swing plate 332 to swing back and forth. In this process, the aluminum profile on the material distribution platform 21 is transferred to the bearing component with the help of the transfer positioning frame 331, until the pressure sensors in multiple bearing components all collect pressure signals, turn off the material distribution drive motor and the swing drive motor, and open the push clamping unit 31 at the same time, and the second longitudinal linear module 313 drives the rotating chuck 311 to move in the direction of the bearing unit 32 , until the rotating chuck 311 is crimped with the end of the aluminum profile, triggering the limit switch, the limit switch opens the rotating chuck 311, and with the help of the rotating chuck 311, one end of the aluminum profile is clamped, and under the action of the second longitudinal linear module 313, the rotating chuck 311 moves forward and rotates at the same time, until the other end of the aluminum profile is aligned with the laser cutting unit 34, at this time, the third laser sensor collects the aluminum profile in place signal, and transmits this signal to the controller, the controller turns on the laser cutting unit 34, and uses the built-in program of the laser cutting unit 34 to punch the aluminum profile, and cuts the aluminum profile after the set length, and the cut aluminum profile falls onto the driving roller group of the burr removal device 4;

[0127] S3. Deburring:

[0128] After the fourth laser sensor collects the signal that the aluminum profile is in place, the abrasive impact unit 41 is turned on. First, the second cylinder 412 drives the synchronous lower pressure plate 413 to move downward a set distance. At this time, the nozzle 415 is aligned with one end of the aluminum profile. Then the second cylinder 412 is closed, and the third longitudinal linear module 411 is opened. The third longitudinal linear module 411 drives the nozzle 415 to move in the direction of the aluminum profile until the nozzle 415 is inserted into the aluminum profile. After the piezoelectric switch on the nozzle 415 senses the insertion signal, the third longitudinal linear module 411 is closed, the normally closed contactor is triggered, the normally closed contactor is opened, the annular electromagnet 4163 loses power, and the second lower pressure plate 4165 is under the action of the first compression spring 4161 The surface of the aluminum profile is pressed down, and then the slurry pump is turned on to extract the abrasive stored in the abrasive storage box 43 and spray it into the interior of the aluminum profile through the nozzle 415. The burrs are removed by the friction between the abrasive and the aluminum profile. The abrasive containing the burrs falls back into the abrasive storage box 43 under the action of gravity, and is sprayed into the interior of the aluminum profile again along the feeding pipe 417 and the nozzle 415 after being filtered by the burr filtering component 44. After the delay setting time, the normally closed contactor is closed, the annular electromagnet 4163 is energized, and the magnetic force is generated by magnetoelectricity to re-adsorb the second lower pressure plate 4165, thereby relieving the pressure outside the aluminum profile. At the same time, the slurry pump is turned off, and the abrasive impact unit 41 is reset to prepare for the next deburring.

[0129] After working for a period of time, the burr removal device 4 is closed, and the extrusion screw 441 is rotated. With the cooperation of the thread of the adjusting screw sleeve, the extrusion screw 441 drives the third lower pressure plate 442 downward to press down the burrs between the primary filter screen 444 and the secondary filter screen 443. The downward pressure is continued to drive the clamping plate 445 downward, open the burr discharge channel 447, and discharge the burrs from here. The extrusion screw 441 is rotated in the opposite direction to drive the third lower pressure plate 442 upward. The clamping plate 445 is reset under the action of the second clamping spring 446, and the burr discharge channel 447 is closed again.

[0130] S4. Welding:

[0131] The staff takes out the aluminum profile after the burrs are removed, and when the aluminum profile is a side beam, it is placed under the first clamping assembly 542, and when the aluminum profile is a connecting beam, it is placed under the second clamping assembly 541 until the upper bracket 9 of the cabin is formed; the first clamping assembly 542 and the second clamping assembly 541 on the welding device 5 are opened, wherein the synchronous drive motor 562 of the first clamping assembly 542 drives the bottom rotating section 5421 to rotate through the synchronous transmission chain 561 and the synchronous transmission sprocket 563, and the bottom rotating section 5421 drives the coaxially connected top threaded section 5422 rotates, and with the cooperation of the threads inside the guide column 5423, the top threaded section 5422 shrinks into the bottom rotating section 5421, driving the horizontal longitudinal pressure rod 5424 to rotate toward the side beam and descend at the same time, until the horizontal longitudinal pressure rod 5424 presses the top of the side beam; at the same time, the third cylinder 5414 of the second clamping assembly 541 extends, driving one end of the lever 5412 to rotate upward, and under the action of the support 5413, the other end of the lever 5412 rotates downward, until the horizontal transverse pressure rod 5411 presses the top of the connecting beam;

[0132] Then, the fourth cylinder 551 is turned on, and the fourth cylinder 551 drives the top swing platform 52 to rotate toward the welding robot 51 until it reaches a set distance and then is closed. At this time, the top swing platform 52 is tilted toward the welding robot 51, and then the welding robot 51 is turned on to perform front welding;

[0133] After the front welding is completed, the welding device 5 is turned off, and the upper bracket 9 of the cabin is taken out and placed backside up on the top swing platform 52, and the welding device 5 is started again, and the backside of the upper bracket 9 of the cabin is welded in the same way;

[0134] S5. Transshipment:

[0135] The vacuum adsorption transfer device 8 is turned on, and the fourth longitudinal linear module 82 drives the vacuum adsorption unit 81 above the welding device 5 to move until the second laser sensor on the top swing platform 52 detects a signal in place, and the sixth cylinder and the vacuum pump are turned on. The sixth cylinder drives the transfer plate and the suction head downward until the upper bracket 9 of the cabin is adsorbed. The vacuum adsorption transfer device 8 runs in the reverse direction, driving the upper bracket 9 of the cabin to move toward the shaping device 6, until the second laser sensor at the top of the shaping platform 61 detects a signal in place, and the vacuum adsorption transfer device 8 places the upper bracket 9 of the cabin between the two shaping units of the shaping platform 61;

[0136] S6, Plastic surgery:

[0137] The shaping unit is opened, and the fifth cylinder 62 drives the trapezoidal block 63 to extend, and under the action of the bevel, drives the shaping block 64 to move toward the position of the side beam of the cabin upper bracket 9, and squeezes and shapes the end of the cabin upper bracket 9;

[0138] S7. After the shaping is completed, the vacuum adsorption transfer device 8 is opened again, and the vacuum adsorption unit 81 above the shaping unit takes out the shaped cabin upper bracket 9. At the same time, the vacuum adsorption unit 81 above the welding device 5 transfers the next cabin upper bracket 9 to be shaped to the shaping platform 61.

[0139] In this embodiment, the upper bracket 9 of the cabin taken out from the shaping device 6 can be transferred to the collection box 7 for centralized placement.

8. The manufacturing process of the cabin upper bracket production equipment according to claim 7, characterized in that: The following steps are involved: S1. Loading: S11. Debugging: With the help of an overhead crane, the bundled aluminum profiles with packaging bags entering the factory are lifted and transferred to the bundle placement platform. One side of the bundled aluminum profile is fitted with the baffle. The horizontal linear module of the bag breaking and feeding device is opened to drive the cutter to move horizontally until the cutter is aligned with the gap between two adjacent aluminum profiles, and then the debugging is stopped. S12, broken bag: With the help of an overhead crane, the bundled aluminum profiles with packaging bags entering the factory are lifted and transported to the bundle placement platform. At this time, the laser emitted by the first laser sensor is blocked and then reflected. After receiving the reflected laser signal, the first laser sensor transmits the signal to the controller. The controller turns on the first longitudinal linear module and the first cylinder of the bag breaking and feeding device. The first cylinder of the bag breaking and feeding device drives the cutting knife to move downward a set distance. At the same time, the first longitudinal linear module drives the cutting knife to move toward the bundled aluminum profile through the first cylinder until the cutting knife extends into the gap between the two aluminum profiles and continues to move along the gap. The packaging bags at the gap are separated by the cutting knife, and the bundled aluminum profile loses the restraint of the packaging bag and spreads out, rolling down along the inclined unloading platform. S13, material division: The aluminum profiles roll down onto the material distribution platform, and the material distribution wheel rotates under the action of the material distribution drive motor. At this time, the material distribution plate outside the material distribution wheel transfers multiple aluminum profiles in sequence to the side of the material distribution platform away from the inclined unloading platform; In this process, since the length of the longitudinally placed aluminum profile is less than the distance between the toggle plate and the material distribution platform, it touches the bottom end of the toggle plate and is changed from longitudinal placement to transverse placement under the action of the toggle plate; S2, cutting and punching: After receiving the signal from the aluminum profile passing through the material distribution wheel, the infrared receiver sends a signal to the cutting and punching device. First, the transfer unit of the cutting and punching device starts to move, and the swing drive motor drives the swing connecting rod to rotate, and the swing connecting rod drives the swing plate to swing back and forth. In this process, the aluminum profile on the material distribution platform is transferred to the bearing assembly with the help of the transfer positioning frame until the pressure sensors in multiple bearing assemblies collect pressure signals, and then the material distribution drive motor and the swing drive motor are turned off. At the same time, the push clamping unit is opened, and the second longitudinal linear module drives the rotating chuck to move toward the bearing unit until the rotating chuck is crimped with the end of the aluminum profile, triggering the limit switch. The limit switch opens the rotating chuck, and clamps one end of the aluminum profile with the help of the rotating chuck. Under the action of the second longitudinal linear module, the rotating chuck moves forward and rotates until the other end of the aluminum profile is aligned with the laser cutting unit. At this time, the third laser sensor collects the aluminum profile in place signal and transmits this signal to the controller. The controller turns on the laser cutting unit, uses the built-in program of the laser cutting unit to punch the aluminum profile, and cuts off the aluminum profile after the set length. The cut aluminum profile falls onto the transmission roller group of the burr removal device; S3. Deburring: After the fourth laser sensor collects the signal that the aluminum profile is in place, the abrasive impact unit is turned on. First, the second cylinder drives the synchronous lower pressure plate to move downward a set distance. At this time, the nozzle is aligned with one end of the aluminum profile, and then the second cylinder is closed, and the third longitudinal linear module is opened. The third longitudinal linear module drives the nozzle to move in the direction of the aluminum profile until the nozzle is inserted into the aluminum profile. After the piezoelectric switch on the nozzle senses the insertion signal, the third longitudinal linear module is closed, the normally closed contactor is triggered, the normally closed contactor is opened, the annular electromagnet loses power, and the second lower pressure plate presses the surface of the aluminum profile under the action of the first compression spring. Then, the slurry pump is turned on to extract the abrasive stored in the abrasive storage box and spray it into the interior of the aluminum profile through the nozzle. The burrs are removed by the friction between the abrasive and the aluminum profile. The abrasive containing burrs falls back into the abrasive storage box under the action of gravity, and is sprayed into the interior of the aluminum profile again along the feeding pipe and the nozzle after being filtered by the burr filtering component. After the delay setting time, the normally closed contactor is closed, the annular electromagnet is energized, and the magnetic force is generated by magnetoelectricity to re-adsorb the second lower pressure plate, relieve the pressure on the outside of the aluminum profile, and at the same time, the slurry pump is turned off, and the abrasive impact unit is reset to prepare for the next deburring. S4. Welding: The staff takes out the aluminum profile after deburring, and places it under the first clamping assembly when the aluminum profile is a side beam, and under the second clamping assembly when the aluminum profile is a connecting beam, until the upper bracket of the cabin is formed; Open the first clamping assembly and the second clamping assembly on the welding device, wherein the synchronous drive motor of the first clamping assembly drives the bottom rotating section to rotate via the synchronous transmission chain and the synchronous transmission sprocket, and the bottom rotating section drives the coaxially connected top threaded section to rotate, and with the cooperation of the thread inside the guide column, the top threaded section shrinks into the bottom rotating section, driving the horizontal longitudinal pressure rod to rotate toward the direction of the side cross beam and descend at the same time, until the horizontal longitudinal pressure rod presses the top of the side cross beam; at the same time, the third cylinder of the second clamping assembly extends out, driving one end of the lever to rotate upward, and under the action of the support, the other end of the lever rotates downward until the horizontal transverse pressure rod presses the top of the connecting beam; Then the fourth cylinder is turned on, and the fourth cylinder drives the top swing platform to rotate toward the welding robot until it reaches a set distance and then is closed. At this time, the top swing platform tilts toward the welding robot, and then the welding robot is turned on for front welding; After the front welding is completed, turn off the welding device, take out the upper bracket of the cabin, and put it back on the top swing platform with the back facing up, and start the welding device again. Similarly, weld the back of the upper bracket of the cabin; S5. Transshipment: Turn on the vacuum adsorption transfer device, and the fourth longitudinal linear module drives the vacuum adsorption unit above the welding device to move until the second laser sensor on the top swing platform detects a signal in place, and turns on the sixth cylinder and the vacuum pump. The sixth cylinder drives the transfer plate and the suction head downward until the upper bracket of the cabin is adsorbed. The vacuum adsorption transfer device runs in the reverse direction, driving the upper bracket of the cabin to move toward the shaping device until the second laser sensor on the top of the shaping platform detects a signal in place, and the vacuum adsorption transfer device places the upper bracket of the cabin between the two shaping units of the shaping platform; S6, Plastic surgery: The shaping unit is opened, and the fifth cylinder drives the trapezoidal block to extend. Under the action of the bevel, the shaping block is driven to move toward the side crossbeam of the upper bracket of the cabin, and the end of the upper bracket of the cabin is squeezed and shaped; S7. After the shaping is completed, the vacuum adsorption transfer device is opened again, and the vacuum adsorption unit above the shaping unit takes out the shaped upper bracket of the cabin, and at the same time, the vacuum adsorption unit above the welding device transfers the next upper bracket of the cabin to be shaped to the shaping platform.
