[0014] A method for taking materials with a pressure-maintaining carrier uses a pressure-maintaining carrier material-taking device, and the specific steps are as follows:

[0015] First step: Place a plurality of empty trays in the material bin of the tray lifting mechanism in sequence. The material bin drives the plurality of trays to be placed on the material bin tray. After the second photoelectric sensor detects that the material bin is in place, the material blocking component limits the material bin, and the lifting drive mechanism drives the lifting plate to drive the material bin to lift to the tray conveying station.

[0016] Second step: The rodless cylinder of the tray conveying mechanism drives the slide cylinder to drive the third jaw cylinder to move to one side of the tray lifting mechanism. The slide cylinder drives the third jaw cylinder to move towards the tray, so that the third jaw cylinder drives the two third jaws to clamp the positioning groove of the tray bottom support.

[0017] Third step: The pressure-maintaining carrier conveying mechanism conveys the pressure-maintaining carrier carrying the product. When it is conveyed to the product discharging station, after the first photoelectric sensor detects that the pressure-maintaining carrier is in place, a blocking component blocks the pressure-maintaining carrier, the barcode scanner scans and transmits the two-dimensional code on the pressure-maintaining carrier, another blocking component blocks the next pressure-maintaining carrier, and the two limiting components respectively limit the two pressure-maintaining carriers.

[0018] Step 4: The disassembly and assembly mechanism of the material taking and disassembly mechanism clamps the cover plate of the pressure maintaining carrier located at the product blanking station, so that the cover plate is disassembled from the base of the pressure maintaining carrier. The material taking mechanism of the material taking and disassembly mechanism clamps the product in the base of the pressure maintaining carrier. The disassembly and assembly mechanism installs the clamped cover plate on the base of the pressure maintaining carrier. The empty pressure maintaining carrier is conveyed to the next workstation by the pressure maintaining carrier conveying mechanism;

[0019] Step 5: The material taking mechanism of the material taking and disassembly mechanism places the clamped product into the tray on the tray conveying mechanism. When the tray is full of products, the tray conveying mechanism transfers the tray to the bin of the tray lifting mechanism, and then the tray conveying mechanism removes the empty tray to the tray conveying station.

[0020] The beneficial effects of this application are as follows:

[0021] This application provides a pressure maintaining carrier material taking device. Through the cooperation of the pressure maintaining carrier conveying mechanism, the material taking and disassembly mechanism, the tray lifting mechanism and the tray conveying mechanism, the device realizes the conveying of the pressure maintaining carrier, the disassembly of the pressure maintaining carrier, the material taking of the product, the assembly of the pressure maintaining carrier, the blanking of the product and the conveying of the tray. The pressure maintaining carrier material taking device realizes the automatic material taking of the product, and also realizes the disassembly and assembly of the pressure maintaining carrier, greatly improving the material taking efficiency of the product, reducing the labor cost and ensuring the quality of the product.

[0022] The pressure maintaining carrier material taking device adopts a material taking and disassembly mechanism.

Cooperating with the material taking and disassembly mechanism, it greatly improves the material taking and disassembly efficiency.

[0024] The pressure maintaining carrier material taking device adopts a tray lifting mechanism to realize the loading and unloading operations of multiple trays, improving the loading and unloading efficiency of the trays.

[0025] The pressure maintaining carrier material taking device adopts a tray conveying mechanism to dock with the tray lifting mechanism to realize the conveying of the tray, and the tray is docked with the material taking and disassembly mechanism to blank the product, improving the blanking efficiency of the product.

[0034] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings.

[0035] As Figure 1 shown, an embodiment of the present invention provides a pressurized carrier material taking device, including a workbench 1. On the workbench 1, there are arranged a pressurized carrier conveying mechanism 2 for conveying the pressurized carrier, a material taking and disassembly / assembly mechanism 3 for disassembling, assembling, and taking materials of the pressurized carrier, a tray conveying mechanism 4 for conveying the tray 46, and a tray lifting mechanism 5 for loading and unloading the tray 46. The pressurized carrier conveying mechanism 2 and the tray conveying mechanism 4 are respectively installed at both ends of the workbench 1. The material taking and disassembly / assembly mechanism 3 is located above the pressurized carrier conveying mechanism 2 and the tray conveying mechanism 4. The tray lifting mechanism 5 is located at the side end of the workbench 1 and corresponds to the tray conveying mechanism 4.

[0036] As Figure 2As shown in the figure, the material taking and disassembly mechanism 3 includes two symmetrically arranged material taking and disassembly components. The material taking and disassembly component includes a first support frame body 31, a three-axis driving mechanism 32, a fixing plate 33, a rotation driving mechanism 34, a connecting plate 35, a material taking mechanism 36 for taking materials from the products in the pressure maintaining carrier, and a disassembly and assembly mechanism 37 for disassembling and assembling the cover plate of the pressure maintaining carrier. The three-axis driving mechanism 32 is installed on the first support frame body 31, and the driving end of the three-axis driving mechanism 32 is connected to the fixing plate 33. The rotation driving mechanism 34 is installed on the fixing plate 33, and the driving end of the rotation driving mechanism 34 is connected to the connecting plate 35. The material taking mechanism 36 and the disassembly and assembly mechanism 37 are respectively installed on two surfaces of the connecting plate 35. The rotation driving mechanism 34 is used to drive the connecting plate 35 to drive the material taking mechanism 36 and the disassembly and assembly mechanism 37 to rotate and adjust the position.

[0037] Specifically, a plurality of empty trays 46 are sequentially placed in the bin 58 of the tray lifting mechanism 5, and then the bin 58 is placed on the bin tray 57 of the tray lifting mechanism 5. After the second photoelectric sensor 512 detects that the bin 58 is in place, the material blocking component 59 limits the bin 58. The lifting driving mechanism 52 drives the lifting plate 53 to drive the bin 58 to lift and lower, so that the topmost tray 46 is lifted and lowered to the tray 46 conveying station. The rodless cylinder 42 of the tray conveying mechanism 4 drives the slide cylinder 43 to drive the clamping cylinder to move to one side of the tray lifting mechanism 5. The slide cylinder 43 drives the clamping cylinder to move towards the tray 46, so that the clamping cylinder drives the two third clamping jaws 45 to clamp the positioning groove at the bottom of the tray 46. The slide cylinder 43 drives the clamping cylinder to drive the tray 46 to retract, and the rodless cylinder 42 and the slide cylinder 43 drive the tray 46 to move to the product feeding station. The pressure maintaining carrier conveying mechanism 2 conveys the pressure maintaining carrier carrying the product. When it is conveyed to the product discharging station, after the first photoelectric sensor 25 detects that the pressure maintaining carrier is in place, a blocking component 24 blocks the pressure maintaining carrier, the barcode scanner 26 scans and transmits back the two-dimensional code on the pressure maintaining carrier, and another blocking component 24 blocks the next pressure maintaining carrier. The two limiting components 27 respectively limit the two pressure maintaining carriers.

[0038] The three-axis drive mechanism 32 of the material taking and disassembling mechanism 3 drives the fixed plate 33 to drive the rotary drive mechanism 34 and the disassembling mechanism 37 to move above the pressure maintaining carrier. The first lifting cylinder 371 of the disassembling mechanism 37 drives the first mounting plate 372 to move towards the pressure maintaining carrier, so that the two first clamping jaws 374 are located on the front and rear sides of the cover plate of the pressure maintaining carrier, and the two pressing heads 376 are located on the left and right sides of the cover plate of the pressure maintaining carrier. The first clamping jaw cylinder 373 drives the two first clamping jaws 374 to clamp the front and rear ends of the cover plate, and the two cover opening cylinders 375 drive the two pressing heads 376 to press the buckles on the left and right ends of the cover plate, so that the two buckles of the cover plate are released from the base of the pressure maintaining carrier. Then, the first lifting cylinder 371 drives the first mounting plate 372 to drive the cover plate to move upward. The rotary drive mechanism 34 drives the connecting plate 35 to drive the disassembling mechanism 37 and the material taking mechanism 36 to rotate, so that the material taking mechanism 36 is located above the base of the pressure maintaining carrier. The second lifting cylinder 361 of the material taking mechanism 36 drives the second mounting plate 362 to drive the profiling pressing block 365 and the second clamping jaw cylinder 363 to move towards the base of the pressure maintaining carrier, so that the profiling pressing block 365 presses the product. After pressing down to the specified pressure, the second clamping jaw cylinder 363 drives the two second clamping jaws 364 to clamp the product, and the second lifting cylinder 361 drives the second mounting plate 362 to drive the product to move upward. The rotary drive mechanism 34 drives the connecting plate 35 to drive the disassembling mechanism 37 and the material taking mechanism 36 to rotate, so that the disassembling mechanism 37 and the cover plate are located above the base of the pressure maintaining carrier. The first lifting cylinder 371 drives the cover plate to move towards the base of the pressure maintaining carrier. When the cover plate is installed on the base of the pressure maintaining carrier, the two cover opening cylinders 375 drive the two pressing heads 376 to release the two buckles of the cover plate, so that the cover plate is buckled on the base of the pressure maintaining carrier. The first clamping jaw cylinder 373 drives the two first clamping jaws 374 to release the cover plate, and the first lifting cylinder 371 drives the first mounting plate 372 to drive the first clamping jaw cylinder 373 and the two cover opening cylinders 375 to move upward. Then, the three-axis drive mechanism 32 drives the fixed plate 33 to drive the material taking mechanism 36 and the product to move above the tray conveying mechanism 4 of the tray 46. The second lifting cylinder 361 moves the product downward and places it in the tray 46. When the tray 46 is full of products, the tray conveying mechanism 4 transfers the tray 46 into the tray lifting mechanism 5. The tray lifting mechanism 5 drives the next empty tray 46 to move to the tray 46 conveying station, and then the tray conveying mechanism 4 transfers the tray 46 to the product discharging station. This pressure maintaining carrier material taking device is a double-station device, and the working principle of the other station is the same as the above working principle.

[0039] In the above structure, through the mutual cooperation of the three-axis drive mechanism 32, the rotary drive mechanism 34, the material taking mechanism 36 and the disassembly and assembly mechanism 37, the cover plate of the pressure maintaining carrier carrying the product is disassembled and assembled, and the product on the base of the pressure maintaining carrier is taken and transferred. The material taking, disassembly and assembly mechanism 3 greatly improves the material taking efficiency of the product, and also improves the disassembly and assembly efficiency of the cover plate of the pressure maintaining carrier. It does not require manual material taking of the product, ensuring the quality and integrity during the product material taking process.

[0040] Such as Figure 3As shown, in one of the embodiments, the disassembly and assembly mechanism 37 of the pressure-holding carrier material taking device includes a first lifting cylinder 371, a first mounting plate 372, a first jaw cylinder 373, two first jaws 374, two cover opening cylinders 375, and two pressing heads 376. The first lifting cylinder 371 is mounted on the connecting plate 35, and the driving end of the first lifting cylinder 371 is connected to the first mounting plate 372. The first jaw cylinder 373 is mounted on the top surface of the first mounting plate 372, and the two driving ends of the first jaw cylinder 373 are respectively connected to the two first jaws 374. The first jaw cylinder 373 is used to drive the two first jaws 374 to clamp the front and rear sides of the cover plate of the pressure-holding carrier. The two cover opening cylinders 375 are respectively mounted on the bottom surface of the first mounting plate 372, and the driving ends of the two cover opening cylinders 375 are respectively connected to the two pressing heads 376. The two cover opening cylinders 375 are used to drive the two pressing heads 376 to open the buckles on the left and right sides of the cover plate of the pressure-holding carrier. Two elastic pressing block assemblies 377 for positioning the cover plate of the pressure-holding carrier are symmetrically arranged on the bottom surface of the first mounting plate 372. When the pressure-holding carrier conveying mechanism 2 transfers the pressure-holding carrier carrying the product to the product blanking station, the three-axis driving mechanism 32 of the material taking and disassembly and assembly mechanism 3 drives the fixing plate 33 to drive the rotary driving mechanism 34 and the disassembly and assembly mechanism 37 to move above the pressure-holding carrier. The first lifting cylinder 371 of the disassembly and assembly mechanism 37 drives the first mounting plate 372 to move towards the pressure-holding carrier, so that the elastic pressing block assemblies 377 are pressed against the cover plate of the pressure-holding carrier to buffer and position the cover plate. The two first jaws 374 are located on the front and rear sides of the cover plate of the pressure-holding carrier, and the two pressing heads 376 are located on the left and right sides of the cover plate of the pressure-holding carrier. The first jaw cylinder 373 drives the two first jaws 374 to clamp the front and rear ends of the cover plate, and the two cover opening cylinders 375 drive the two pressing heads 376 to press the buckles on the left and right ends of the cover plate, so that the two buckles of the cover plate are loosened from the base of the pressure-holding carrier. Then, the first lifting cylinder 371 drives the first mounting plate 372 to drive the cover plate to move upward. After the material taking mechanism 36 clamps the product in the pressure-holding carrier, the rotary driving mechanism 34 drives the connecting plate 35 to drive the disassembly and assembly mechanism 37 and the material taking mechanism 36 to rotate, so that the cover plate on the disassembly and assembly mechanism 37 is located above the base of the pressure-holding carrier. The first lifting cylinder 371 drives the cover plate to move towards the base of the pressure-holding carrier. When the cover plate is installed on the base of the pressure-holding carrier, the two cover opening cylinders 375 drive the two pressing heads 376 to loosen the two buckles of the cover plate, so that the cover plate is buckled on the base of the pressure-holding carrier. The first jaw cylinder 373 drives the two first jaws 374 to loosen the cover plate, and the first lifting cylinder 371 drives the first mounting plate 372 to drive the first jaw cylinder 373 and the two cover opening cylinders 375 to move upward. The setting of this disassembly and assembly mechanism 37 greatly improves the efficiency of disassembling and assembling the cover plate of the pressure-holding carrier, and also improves the accuracy of disassembly and assembly.

[0041] As Figure 3As shown, in one of the embodiments, the material taking mechanism 36 of the pressure maintaining carrier material taking device includes a second lifting cylinder 361, a second mounting plate 362, a second jaw cylinder 363, two second jaws 364, a profiling block 365, a spring 366, and a pressure sensor 367. The second lifting cylinder 361 is installed on the connecting plate 35, the driving end of the second lifting cylinder 361 is connected to the second mounting plate 362, the second jaw cylinder 363 is installed on the second mounting plate 362, and the two driving ends of the second jaw cylinder 363 are respectively connected to the two second jaws 364. The top of the profiling block 365 is connected to one end of the spring 366, the other end of the spring 366 is connected to one end of the pressure sensor 367, the other end of the pressure sensor 367 is connected to the top of the second mounting plate 362, and the side end of the profiling block 365 is slidably matched with the second mounting plate 362. The two second jaws 364 are respectively located on both sides of the profiling block 365. When the disassembly and assembly mechanism 37 clamps the cover plate of the pressure maintaining carrier, the rotation driving mechanism 34 drives the connecting plate 35 to drive the disassembly and assembly mechanism 37 and the material taking mechanism 36 to rotate, so that the material taking mechanism 36 is located above the base of the pressure maintaining carrier. The second lifting cylinder 361 of the material taking mechanism 36 drives the second mounting plate 362 to drive the profiling block 365 and the second jaw cylinder 363 to move towards the base of the pressure maintaining carrier, so that the profiling block 365 presses the product. The profiling block 365 is stressed to compress the spring 366, and the spring 366 compresses the pressure sensor 367. When the specified pressure is reached, the second jaw cylinder 363 drives the two second jaws 364 to clamp the product, and the second lifting cylinder 361 drives the second mounting plate 362 to drive the product to move upward. The setting of the material taking mechanism 36 not only improves the material taking efficiency and material taking accuracy of the product, but also facilitates the control of the pressure value of the product.

[0042] As Figure 2As shown, in one embodiment, the three-axis drive mechanism 32 of the pressure-holding vehicle material taking device includes a first linear module 321 that moves in the X-axis direction, a second linear module 322 that moves in the Y-axis direction, and a third linear module 323 that moves in the Z-axis direction. The first linear module 321 is installed at one end of the first support frame 31. The driving end of the first linear module 321 is connected to one end of the second linear module 322. The other end of the second linear module 322 is slidably engaged with the other end of the first support frame 31. The driving end of the second linear module 322 is connected to the third linear module 323. The driving end of the third linear module 323 is connected to the fixing plate 33.

The setting of this three-axis drive mechanism 32 facilitates driving the material taking mechanism 36 and the disassembly and assembly mechanism 37 to move in three-axis directions.

[0043] As Figure 4As shown, in one of the embodiments, the pressure-holding carrier conveying mechanism 2 of the pressure-holding carrier material-taking device includes two symmetrically arranged pressure-holding carrier conveying components. The pressure-holding carrier conveying component includes a conveying line support frame 21, an upper conveying line component 22 for conveying the pressure-holding carrier, and a lower conveying line component 23 for docking with other workstations. The upper conveying line component 22 and the lower conveying line component 23 are installed in parallel on the conveying line support frame 21. The upper conveying line component 22 is located above the lower conveying line component 23. On the upper conveying line component 22, there are two blocking components 24 for blocking and separating the pressure-holding carrier, a first photoelectric sensor 25 for detecting whether the pressure-holding carrier moves in place, a barcode scanner 26, and two limiting components 27 for limiting the pressure-holding carrier. The blocking component 24 includes a blocking cylinder and a blocking block. The driving end of the blocking cylinder is connected to the blocking block. The blocking cylinder is used to drive the blocking block to block the pressure-holding carrier. The limiting component 27 includes two limiting cylinders and two limiting claws. The two limiting cylinders are symmetrically installed at both ends of the upper conveying line component 22. The driving ends of the two limiting cylinders are respectively connected to the two limiting claws. The two limiting cylinders are used to drive the two limiting claws to limit the pressure-holding carrier. The first photoelectric sensor 25 and the barcode scanner 26 are respectively located on one side of the blocking component 24. The upper conveying line component 22 conveys the pressure-holding carrier carrying the product. When it is conveyed to the product blanking station, after the first photoelectric sensor 25 detects that the pressure-holding carrier is in place, the blocking cylinder of one blocking component 24 drives the blocking block to block the pressure-holding carrier, and the barcode scanner 26 scans and transmits back the two-dimensional code on the pressure-holding carrier. The blocking cylinder of the other blocking component 24 drives the blocking block to block the next pressure-holding carrier. The limiting cylinders of the two limiting components 27 respectively limit the two pressure-holding carriers with the limiting claws. When the product in the pressure-holding carrier is transferred, the upper conveying component transfers the empty pressure-holding carrier to the next station. The lower conveying line component 23 is docked with other workstations to convey the pressure-holding carrier. The setting of this pressure-holding carrier conveying component facilitates the conveying, blocking, and limiting of the pressure-holding carrier, and cooperates with the material-taking disassembly and assembly mechanism 3, greatly improving the material-taking and disassembly and assembly efficiency.

[0044] As Figure 4As shown, in one embodiment, the upper conveyor line assembly 22 and the lower conveyor assembly of the pressure-holding carrier material-taking device both include a conveyor frame body 201, a stepping motor 202, a synchronous belt drive assembly 203, and a conveyor line 204. The stepping motor 202 is installed on the conveyor frame body 201. The driving end of the stepping motor 202 is connected to one end of the synchronous belt drive assembly 203, and the other end of the synchronous belt drive assembly 203 is connected to the conveyor line 204. The stepping motor 202 is used to drive the synchronous belt rotating assembly to drive the conveyor line 204 to rotate. The stepping motor 202 drives the synchronous belt drive assembly 203 to rotate, the synchronous belt drive assembly 203 drives the conveyor line 204 to rotate, and the conveyor line 204 conveys the pressure-holding carrier. This setting facilitates the conveyance of the pressure-holding carrier.

[0045] As Figure 5 As shown, in one embodiment, the tray lifting mechanism 5 of the pressure-holding carrier material-taking device includes two symmetrically arranged tray 46 lifting assemblies. The tray 46 lifting assembly includes a second support frame body 51, a lifting drive mechanism 52, a lifting plate 53, a guide post assembly 54, a lifting lead screw assembly 55, a mounting plate 56, and a magazine tray 57 for placing the tray 46. The lifting drive mechanism 52 is installed on the second support frame body 51. The driving end of the lifting drive mechanism 52 is connected to one end of the lifting lead screw assembly 55. The lifting lead screw assembly 55 is connected to the lifting plate 53 through a lead screw nut. The other end of the lifting lead screw assembly 55 is connected to the middle part of the mounting plate 56. One end of the guide post assembly 54 is connected to the top of the second support frame body 51. The guide post assembly 54 is connected to the lifting plate 53 through a linear bearing. The other end of the guide post assembly 54 is connected to both ends of the mounting plate 56. The bottom of the magazine tray 57 is connected to the lifting plate 53 through a connecting column. A magazine 58 for stacking and placing a plurality of trays 46 is provided on the magazine tray 57. A material blocking assembly 59 for blocking the magazine 58 is provided on one side of the magazine 58. The lifting lead screw assembly 55 includes two lifting lead screws. The guide post assembly 54 includes four guide posts. The material blocking assembly 59 includes a material blocking cylinder and a limit block. The lifting drive mechanism 52 drives the two lifting lead screws to rotate. The lifting lead screws rotate, causing the lead screw nut to drive the lifting plate 53 to move up and down along the lifting lead screws. The four end corners of the lifting plate 53 move up and down along the four guide posts respectively. The movement of the lifting plate 53 drives the magazine tray 57 to move up and down. The magazine tray 57 drives the magazine 58 and a plurality of trays 46 to move up and down, so that the topmost tray 46 is located at the tray 46 conveying station and is docked with the tray conveying mechanism 4. When the tray 46 is filled with products, the lifting drive mechanism 52 drives the magazine tray 57 to move upward, so that the empty storage position of the magazine 58 corresponds to the tray conveying mechanism 4. The tray conveying mechanism 4 transfers the tray 46 filled with products to the empty storage position of the magazine 58. This setting facilitates driving the magazine tray 57 to drive the magazine 58 and the tray 46 to lift, improving the loading and unloading efficiency of the tray 46.

[0046] As Figure 6 shown, in one embodiment, a dust cover 510 for dust prevention and an opposed photoelectric sensor 511 for safety protection are provided at one end of the tray lifting mechanism 5 of the pressure-holding carrier material taking device. A second photoelectric sensor 512 for detecting whether the magazine 58 is in place is provided on the mounting plate 56. The lifting drive mechanism 52 includes a lifting motor 521 and a synchronous pulley drive assembly 522. The lifting motor 521 is installed on the second support frame 51. The drive end of the lifting motor 521 is connected to one end of the synchronous pulley drive assembly 522, and the other end of the synchronous pulley drive assembly 522 is connected to the lifting lead screw assembly 55. The lifting motor 521 is used to drive the synchronous pulley drive assembly 522 to drive the lifting lead screw assembly 55 to rotate. When the magazine 58 is manually transferred onto the magazine tray 57, the opposed photoelectric sensor 511 emits a non-start signal to ensure the safety of personnel. The dust cover 510 plays a role in dust prevention for the tray lifting mechanism 5. The lifting motor 521 drives the synchronous pulley drive assembly 522 to rotate, and the synchronous pulley drive assembly 522 drives the two lifting lead screws to rotate, so that the lifting plate 53 drives the magazine tray 57 to move up and down. The setting of the lifting drive mechanism 52 facilitates driving the magazine tray 57 to drive the magazine 58 and the tray 46 to move up and down. The setting of the second photoelectric sensor 512 facilitates detecting whether the magazine 58 is placed in place. After being placed in place, the stop air cylinder drives the limit block to limit the magazine 58. This setting facilitates the detection and limitation of the magazine 58.

[0047] As Figure 5As shown, in one of the embodiments, the tray conveying mechanism 4 of the pressure-holding carrier material taking device includes two symmetrically arranged tray conveying components. Each tray conveying component includes a conveying support base 41, a rodless cylinder 42, a slide cylinder 43, a third jaw cylinder 44, and two third jaws 45. The rodless cylinder 42 is installed on the conveying support base 41. The driving end of the rodless cylinder 42 is connected to the slide cylinder 43. The driving end of the slide cylinder 43 is connected to the third jaw cylinder 44. The driving end of the third jaw cylinder 44 is connected to the two third jaws 45. The third jaw cylinder 44 is used to drive the third jaws 45 to clamp the positioning groove of the bottom tray of the tray 46. The two ends of the bottom tray of the tray 46 are slidably matched with the inner side of the conveying support base 41. After the tray lifting mechanism 5 drives the empty tray 46 at the top to the in-place position, the rodless cylinder 42 drives the slide cylinder 43 to drive the third jaw cylinder 44 to move to one side of the tray lifting mechanism 5. The slide cylinder 43 drives the third jaw cylinder 44 to move towards the tray 46, so that the third jaw cylinder 44 drives the two third jaws 45 to clamp the positioning groove of the bottom tray of the tray 46. The slide cylinder 43 drives the third jaw cylinder 44 to drive the tray 46 to retract. The rodless cylinder 42 and the slide cylinder 43 drive the tray 46 to move to the product loading and unloading station, so that the material taking mechanism 36 of the material taking and disassembling mechanism 3 places the product in the tray 46. When the tray 46 is full of products, the rodless cylinder 42 drives the slide cylinder 43 to drive the third jaw cylinder 44 to transfer the tray 46 to the empty storage position of the storage bin 58, and then moves the empty tray 46 out to the tray 46 conveying station. This setting facilitates the conveying of the tray 46 and improves the loading and unloading efficiency of the product.

[0048] As Figure 1 shown, an embodiment of the present invention also provides a method for taking materials with a pressure-holding carrier, using a pressure-holding carrier material taking device. The specific steps are as follows:

[0049] First step: Place a plurality of empty trays 46 in the storage bin 58 of the tray lifting mechanism 5 in sequence. The storage bin 58 drives the plurality of trays 46 to be placed on the storage bin tray 57. After the second photoelectric sensor 512 detects that the storage bin 58 is in place, the material blocking component 59 limits the storage bin 58, and the lifting drive mechanism 52 drives the lifting plate 53 to drive the storage bin 58 to lift to the tray 46 conveying station;

[0050] Second step: The rodless cylinder 42 of the tray conveying mechanism 4 drives the slide cylinder 43 to drive the third jaw cylinder 44 to move to one side of the tray lifting mechanism 5. The slide cylinder 43 drives the third jaw cylinder 44 to move towards the tray 46, so that the third jaw cylinder 44 drives the two third jaws 45 to clamp the positioning groove of the bottom tray of the tray 46. The slide cylinder 43 drives the third jaw cylinder 44 to drive the tray 46 to retract. The rodless cylinder 42 and the slide cylinder 43 drive the tray 46 to move to the product loading and unloading station;

[0051] Step 3: The pressure-holding carrier conveying mechanism 2 conveys the pressure-holding carrier carrying the product. When it is conveyed to the product blanking station, after the first photoelectric sensor 25 detects that the pressure-holding carrier is in place, a blocking component 24 blocks the pressure-holding carrier. The code scanning gun 26 scans and transmits the two-dimensional code on the pressure-holding carrier, and another blocking component 24 blocks the next pressure-holding carrier. Two limiting components 27 limit the two pressure-holding carriers respectively;

[0052] Step 4: The disassembly and assembly mechanism 37 of the material taking and disassembly mechanism 3 clamps the cover plate of the pressure-holding carrier located at the product blanking station, so that the cover plate is disassembled from the base of the pressure-holding carrier. The material taking mechanism 36 of the material taking and disassembly mechanism 3 clamps the product in the base of the pressure-holding carrier. The disassembly and assembly mechanism 37 installs the clamped cover plate on the base of the pressure-holding carrier. The empty pressure-holding carrier is conveyed to the next station by the pressure-holding carrier conveying mechanism 2;

[0053] Step 5: The material taking mechanism 36 of the material taking and disassembly mechanism 3 places the clamped product into the tray 46 on the tray conveying mechanism 4. When the tray 46 is full of products, the tray conveying mechanism 4 transfers the tray 46 to the storage bin 58 of the tray lifting mechanism 5, and the tray conveying mechanism 4 then moves the empty tray 46 out to the tray 46 conveying station.

[0054] This method for taking materials from the pressure-holding carrier disassembles and assembles the cover plate of the pressure-holding carrier carrying the product, and takes and transfers the product on the base of the pressure-holding carrier. This method for taking materials from the pressure-holding carrier greatly improves the material taking efficiency of the product, and also improves the disassembly and assembly efficiency of the cover plate of the pressure-holding carrier. It does not require manual material taking for the product, ensuring the quality and integrity during the product material taking process.

[0055] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
