With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0089] Since soft-pack batteries are closed-mouth batteries, they cannot be evacuated during the formation process.

After formation, the air bag needs to be punctured and negative pressure needs to be extracted to discharge the gas in the air bag, and then the air bag needs to be re-sealed. At present, the puncturing, extraction of negative pressure and sealing of the air bag are all performed manually, and the efficiency of manual operation is low, resulting in low production efficiency of the current batteries.

The puncturing mechanism can puncture the workpiece in the accommodating cavity to release the gas in the workpiece. The negative pressure mechanism can draw negative pressure to the accommodating cavity, thereby extracting the gas in the punctured workpiece. The heat sealing mechanism can heat-seal the punctured workpiece again. The packaging device can automatically complete the puncturing, gas extraction and packaging of the workpiece with high efficiency and good quality.

[0102] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 4 A schematic diagram of the structure of the first positioning mechanism 200 provided for some embodiments of the present application. In some embodiments, the accommodating cavity 110 has a first opening 111. The first positioning mechanism 200 includes a movable component 210, and the movable component 210 has a first position and a second position. The movable component 210 includes a support member 212 and a blocking member 211, and the support member 212 is used to support a workpiece, and the support member 212 is connected to the blocking member 211. When the movable component 210 is located in the first position, the support member 212 is located outside the accommodating cavity 110, and the blocking member 211 opens the first opening 111. When the movable component 210 is located in the second position, the support member 212 is located inside the accommodating cavity 110, and the blocking member 211 blocks the first opening 111.

[0103] The accommodating chamber 110 has a first opening 111 , and the first opening 111 enables a workpiece to enter and leave the accommodating chamber 110 .

The movable assembly 210 includes a support member 212 and a blocking member 211, wherein the support member 212 can support the workpiece, and the blocking member 211 can open or block the first opening 111. When the blocking member 211 blocks the first opening 111, the accommodating chamber 110 is a closed space, so that negative pressure can be extracted from the accommodating chamber 110 by the negative pressure mechanism 400.

[0105] When the movable assembly 210 is located at the first position, the support member 212 is located outside the accommodating chamber 110, and the blocking member 211 opens the first opening 111. At this time, the support member 212 sends out the processed workpiece or is ready to receive the workpiece to be processed. When the movable assembly 210 is located at the second position, the support member 212 is located inside the accommodating chamber 110, the blocking member 211 blocks the first opening 111, and the workpiece is processed inside the accommodating chamber 110.

[0106] When the movable component 210 transfers the workpiece from the outside of the accommodating chamber 110 to the inside of the accommodating chamber 110, the blocking member 211 will gradually block the first opening 111. In this way, the action of transferring the workpiece to the accommodating chamber 110 and the action of blocking the first opening 111 are combined into one action, which is conducive to reducing the action time and improving efficiency. Similarly, when the movable component 210 transfers the workpiece from the inside of the accommodating chamber 110 to the outside of the accommodating chamber 110, the blocking member 211 will gradually open the first opening 111. In this way, the action of transferring the workpiece to the outside of the accommodating chamber 110 and the action of opening the first opening 111 are combined into one action, which is conducive to reducing the action time and improving efficiency.

[0110] By providing the positioning assembly 220 to position the workpiece, on the one hand, the risk of displacement of the workpiece during the movement of the movable assembly 210 is reduced. On the other hand, when the piercing mechanism 300, the negative pressure mechanism 400 and the heat sealing mechanism 500 process the workpiece, the workpiece is not easily deviated, which is conducive to improving the processing quality.

[0111] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the positioning assembly 220 includes a first positioning member 221, a second positioning member 222, and a third positioning member 223.

Along the second direction, the two ends of the workpiece form a second abutting side and a third abutting side respectively, and the second positioning member 222 and the third positioning member 223 abut against the second abutting side and the third abutting side of the workpiece respectively. The processing area of ​​the workpiece is vacated to facilitate puncturing by the puncturing mechanism 300.

[0114] When the workpiece is a battery, the processing area of ​​the workpiece is the side where the air bag of the battery is located.

[0117] The first driving member 224 is used to provide driving force for the first positioning member 221 , the second positioning member 222 and the third positioning member 223 , so that the first positioning member 221 , the second positioning member 222 and the third positioning member 223 are close to each other and cooperate to clamp the workpiece.

[0118] The transmission mechanism 225 is a structure that connects the first positioning member 221, the second positioning member 222, the third positioning member 223 and the first driving member 224. The transmission mechanism 225 transmits the power of the first driving member 224 to the first positioning member 221, the second positioning member 222 and the third positioning member 223, so as to drive the first positioning member 221, the second positioning member 222 and the third positioning member 223 to slide relative to the supporting member 212.

The second driving member 620 is used to drive the pressing plate 610 to approach the movable assembly 210 located at the second position to press the workpiece. The pressure detection mechanism 630 is used to detect the pressure of the pressing plate 610. The second driving member 620 responds to the pressure detection mechanism 630.

[0137] The pressing plate 610 is a component for directly contacting and pressing the workpiece in the accommodating chamber 110. The pressing plate 610 is a plate-shaped structure.

Along the third direction, the first receiving member 330 is disposed opposite to the bayonet assembly 310. The first receiving member 330 is used to receive liquid leaked from the workpiece.

[0147] Taking the workpiece as a battery as an example, after the air bag is punctured, the electrolyte in the battery may flow out from the punctured position. That is, when the workpiece is a battery, the liquid may be the electrolyte.

[0148] The first receiving member 330 is a structure for collecting liquid leaking from the punctured workpiece. The first receiving member 330 can be a box body, a cup body, a barrel body, etc.

[0149] Along the third direction, the first receiving piece 330 is disposed opposite to the bayonet assembly 310 , and the opening end of the first receiving piece 330 faces the bayonet assembly 310 , so as to receive the liquid leaked from the workpiece.

[0150] The first receiving member 330 is provided to receive the liquid leaking from the workpiece, thereby reducing the risk of the liquid dripping onto other functional components and causing the other functional components to rust, which is beneficial to improving the life of the packaging device 10 .

[0153] The fourth driving member 340 is provided to drive the first receiving member 330 to move along the third direction, and the position of the first receiving member 330 in the third direction is adjusted so that the first receiving member 330 can be close to the workpiece, thereby reducing the risk of liquid splashing onto other functional components.

[0154] Please refer to Figure 5 and Figure 6 , Figure 6 A schematic diagram of the structure of a packaging device 10 (the back plate 130 opens the second opening 112) provided in some embodiments of the present application. In some embodiments, the first housing 100 includes a frame 120 and a back plate 130, and the accommodating cavity 110 is formed in the frame 120. The accommodating cavity 110 has a first opening 111 and a second opening 112 opposite to each other, and the first opening 111 is used for a workpiece to enter the accommodating cavity 110. The back plate 130 is movably connected to the frame 120, and the back plate 130 is used to open or close the second opening 112.

[0155] The frame 120 may be a square frame or a round frame. The hollow space of the frame 120 forms the aforementioned accommodating chamber 110. The accommodating chamber 110 has a first opening 111 and a second opening 112 opposite to each other. The first opening 111 and the second opening 112 may also be understood as openings at both ends of the frame 120.

[0156] The back plate 130 is movably connected to the frame 120, and the back plate 130 can move relative to the frame 120 to open or close the second opening 112. When the packaging device 20 is working, the back plate 130 closes the second opening 112 to seal the accommodating chamber 110, so that the negative pressure mechanism 400 can extract negative pressure from the accommodating chamber 110. When the packaging device 10 fails, the back plate 130 can be adjusted so that the back plate 130 opens the second opening 112 to facilitate maintenance of the packaging device 10.

[0157] By movably connecting the back plate 130 and the frame 120 , the back plate 130 can open or close the second opening 112 . Thus, when the packaging device 10 fails, the second opening 112 can be opened for maintenance, which is more convenient.

[0158] Please refer to Figure 5 and Figure 6 In some embodiments, the back plate 130 is rotatably disposed on the frame 120 , and the puncturing mechanism 300 is disposed on the back plate 130 .

[0159] “The back plate 130 is rotatably disposed on the frame 120 ” means that the back plate 130 is rotatably connected to the frame 120 . The back plate 130 can rotate relative to the frame 120 to open or close the second opening 112 .

[0160] The puncturing mechanism 300 is connected to the back plate 130 , and when the back plate 130 opens the second opening 112 , the puncturing mechanism 300 can be exposed.

[0161] By disposing the puncturing mechanism 300 on the back plate 130 , when the back plate 130 opens the second opening 112 , the puncturing mechanism 300 can be exposed, so that the puncturing mechanism 300 can be easily maintained.

[0162] In some embodiments, the packaging device 10 includes a first adjustment mechanism, which connects the frame 120 and the back plate 130 , and is used to drive the back plate 130 to rotate relative to the frame 120 .

[0163] The first adjustment mechanism may be a manual adjustment mechanism. For example, the first adjustment mechanism includes an adjustment hand wheel, and the back plate 130 is driven to rotate relative to the frame 120 by rotating the adjustment hand wheel.

[0164] The first adjustment mechanism may also be an automatic adjustment mechanism. For example, the first adjustment mechanism includes a motor, and the motor drives the back plate 130 to rotate relative to the frame 120 .

[0165] By providing the first adjustment mechanism to drive the back plate 130 to open or close the first opening 111 , it is helpful to control the opening angle of the back plate 130 .

[0166] Please refer to Figure 5 and Figure 6 In some embodiments, the heat sealing mechanism 500 includes a first sealing knife 510, a first sealing knife driving member 520, a second sealing knife 530, and a second sealing knife driving member 540. The first sealing knife 510 and the second sealing knife 530 are arranged opposite to each other along the third direction. The first sealing knife driving member 520 is connected to the first housing 100 and the first sealing knife 510, and the first sealing driving member is used to drive the first sealing knife 510 to move along the third direction. The second sealing knife driving member 540 is connected to the first housing 100 and the second sealing knife 530, and the second sealing knife driving member 540 is used to drive the second sealing knife 530 to move along the third direction. The first sealing knife 510 and the second sealing knife 530 are used to cooperate in heat sealing a workpiece.

[0167] Optionally, along the first direction, the heat sealing mechanism 500 is located between the puncturing mechanism 300 and the blocking member 211. Taking a battery as an example, the workpiece includes a body and an air bag. Along the first direction, the puncturing mechanism 300 can puncture an end of the air bag away from the body, and the heat sealing mechanism 500 can heat seal the portion of the air bag between the puncturing position and the body, that is, the heat sealing mechanism 500 can heat seal an end of the air bag close to the body.

[0168] Please refer to Figure 7 , Figure 7A schematic diagram of the structure of a packaging device 20 provided in some embodiments of the present application. The present application also provides a packaging device 20, which includes the above-mentioned packaging device 10, a weighing device 700, a cutting device 800 and a transfer mechanism 900, wherein the weighing device 700 is used to weigh the workpiece, the cutting device 800 is used to cut the workpiece, and the transfer mechanism 900 is used to realize the switching of the workpiece between the packaging device 10, the weighing device 700 and the cutting device 800.

[0169] The weighing device 700 is a structure for weighing the workpiece to analyze and determine whether the workpiece meets the requirements. In the production process, the workpiece can be weighed once before entering the packaging device 10 to determine whether it meets the requirements. After the workpiece leaves the packaging device 10, the workpiece is weighed again to determine whether it still meets the requirements after being processed by the packaging device 10, so as to eliminate defective products processed by the packaging device 10.

[0170] The cutting device 800 is a structure for cutting a workpiece. When the workpiece is a battery, the cutting mechanism 810 can be used to cut the punctured part of the airbag.

[0171] The transfer mechanism 900 is a structure for realizing the switching of the workpiece between the packaging device 10, the weighing device 700 and the cutting device 800. For example, the transfer mechanism 900 may include a loading mechanism 920, a picking mechanism 910, a unloading mechanism 930 and the like.

[0172] Please refer to Figure 7 In some embodiments, the packaging equipment 20 includes a second adjustment mechanism 140, which is connected to the packaging device 10, and the second adjustment mechanism 140 is used to adjust the tilt angle of the packaging device 10 to adjust the tilt angle of the workpiece.

[0173] The second adjustment mechanism 140 may be a manual adjustment mechanism. For example, the second adjustment mechanism 140 includes an adjustment hand wheel, and the tilt angle of the packaging device 10 is adjusted by rotating the adjustment hand wheel.

[0174] The second adjustment mechanism 140 may also be an automatic adjustment mechanism. For example, the second adjustment mechanism 140 includes a motor, and the tilt angle of the packaging device 10 is adjusted by the motor.

[0175] Since the workpiece is positioned by the first positioning mechanism 200 , when the packaging device 10 is tilted as a whole, the workpiece positioned by the first positioning mechanism 200 will also tilt.

[0176] Taking the workpiece as a battery as an example, the battery contains electrolyte. By tilting the workpiece upward, the outflow of electrolyte from the punctured air bag can be reduced.

[0177] By providing the second adjustment mechanism 140 to adjust the tilt angle of the packaging device 10 , the workpiece can be tilted upward, thereby reducing the risk of liquid leakage in the workpiece.

[0178] Please refer to Figure 7 and Figure 8 , Figure 8 A schematic diagram of the structure of a weighing device 700 provided in some embodiments of the present application. In some embodiments, the weighing device 700 includes a tray 710, a weighing mechanism 720 and a lifting mechanism 730. The tray 710 is used to support a workpiece, and the weighing mechanism 720 is arranged below the tray 710. The lifting mechanism 730 includes a movable member 731 that can move along the lifting direction of the lifting mechanism 730. Along the lifting direction, the tray 710 is movably arranged on the movable member 731. A limiting member 732 is arranged on the movable member 731. The limiting member 732 is used to support the tray 710 and drive the tray 710 to rise when the movable member 731 rises. The limiting member 732 is also used to separate from the tray 710 when the movable member 731 falls, so that the tray 710 falls on the weighing mechanism 720, so that the weighing mechanism 720 weighs the workpiece and the tray 710.

[0179] Please refer to Figure 8 , the lifting direction of the lifting mechanism 730 may be the C direction shown in the figure. Optionally, the lifting direction of the lifting mechanism 730 is the same as the third direction, that is, Figure 6 The Z direction shown in Figure 8 The C direction shown in is the same direction.

[0180] In some embodiments, the third direction and the lifting direction of the lifting mechanism 730 are both the direction of gravity.

[0181] The tray 710 is a component for supporting the workpiece. The tray 710 may be a disk-shaped structure or other structures. For example, please refer to Figure 8 , Figure 8 The tray 710 shown in FIG. 7 is a rectangular plate-shaped structure.

[0182] The weighing mechanism 720 is a structure for weighing the workpiece. The weighing mechanism 720 is disposed below the tray 710. The weighing mechanism 720 can weigh the tray 710 and the workpiece as a whole, thereby calculating the weight of the workpiece. The weighing mechanism 720 can be a weighing sensor, an electronic scale, or the like.

[0183] The lifting mechanism 730 is a mechanism for driving the tray 710 to rise and fall. The lifting mechanism 730 includes a fixed part and a movable part 731, wherein the fixed part is fixed in position, and the movable part 731 is movably arranged on the movable part 731 along the lifting direction of the lifting mechanism 730. For example, the lifting mechanism 730 can be a cylinder. In this case, the fixed part is the cylinder barrel of the cylinder. The movable part 731 is the piston rod of the cylinder.

[0184] The tray 710 is movably arranged on the movable member 731 along the lifting direction of the lifting mechanism 730. The movable member 731 is provided with a limit member 732, and the limit member 732 rises and falls with the lifting and lowering of the movable member 731. When the tray 710 contacts the weighing mechanism 720, the limit member 732 separates from the tray 710. At this time, the limit member 732 is located below the tray 710. When the movable member 731 rises, the limit member 732 gradually approaches the tray 710, and finally contacts the tray 710 and drives the tray 710 to rise, so that the tray 710 is separated from the weighing mechanism 720, so that the tray 710 can receive the workpiece or send the workpiece out.

[0185] The tray 710 can support the workpiece, and the workpiece will not directly contact the weighing mechanism 720, which reduces the risk of the workpiece damaging the weighing mechanism 720 and helps to extend the life of the weighing mechanism 720. The tray 710 is movably arranged on the movable member 731. When the movable member 731 rises, the limiter 732 on the movable member 731 can contact the tray 710 and drive the tray 710 to rise, so that the tray 710 can receive the workpiece provided by the transfer mechanism 900. When the movable member 731 descends, the tray 710 descends accordingly until the tray 710 falls on the weighing mechanism 720, and the limiter 732 separates from the tray 710. In this way, the lifting mechanism 730 will not affect the weighing of the weighing mechanism 720, and the weighing mechanism 720 can weigh the tray 710 and the workpiece as a whole, thereby obtaining the weight of the workpiece, so as to judge whether the workpiece meets the requirements.

[0186] Please refer to Figure 7 and Figure 8 In some embodiments, the packaging device 20 includes a second housing 740, the second housing 740 includes a weighing cavity, and the top of the weighing cavity has a third opening 741 for allowing the workpiece to enter the weighing cavity.

The tray 710 and the weighing mechanism 720 are both arranged in the weighing cavity.

[0188] By arranging the tray 710 and the weighing mechanism 720 in the weighing chamber, external interference is reduced, which is beneficial to improving the weighing accuracy of the weighing mechanism 720.

[0189] Please refer to Figure 7 and Figure 8In some embodiments, the weighing device 700 includes a blocking mechanism 750 , and the blocking mechanism 750 is used to open or close the third opening 741 .

[0190] When the blocking mechanism 750 opens the third opening 741, the workpiece can enter or leave the weighing chamber through the third opening 741. When the blocking mechanism 750 closes the third opening 741, the weighing chamber is a closed chamber. The weighing mechanism 720 in the weighing chamber is not easily disturbed by the outside world, which is conducive to improving the weighing accuracy of the weighing mechanism 720.

[0191] Optionally, the sealing mechanism 750 includes a sealing member 752 and a sealing driving member 751, wherein the sealing member 752 is slidably disposed on the second shell 740, the sealing driving member 751 connects the second shell 740 and the sealing member 752, and the sealing driving member 751 is used to drive the sealing member 752 to slide relative to the second shell 740 so that the sealing member 752 opens or closes the third opening 741.

[0192] The blocking mechanism 750 can open the third opening 741 to allow the workpiece to enter or leave the weighing chamber. The blocking mechanism 750 can close the third opening 741 so that the weighing mechanism 720 can weigh the workpiece in a closed environment, which is beneficial to improving the weighing accuracy of the weighing mechanism 720.

[0193] Please refer to Figure 7 and Figure 8 In some embodiments, the weighing device 700 includes a second receiving member 760, which is disposed in the weighing cavity and is used to receive liquid leaking from the workpiece.

When the tray 710 contacts the weighing mechanism 720, the second receiving member 760 is located below the tray 710 along the lifting direction of the lifting mechanism 730. The second receiving member 760 may also be movably connected to the second housing 740 along the lifting direction. The second receiving member 760 is always located below the tray 710 and rises and falls with the tray 710.

[0197] The second receiving member 760 is provided to receive the liquid leaking from the workpiece, thereby reducing the risk of the liquid dripping onto other functional components and causing the other functional components to rust, which is beneficial to improving the life and accuracy of the weighing device 700.

When the second positioning mechanism 820 is in the fourth position, the workpiece is arranged relative to the cutter 812 along the fourth direction, so that the cutting mechanism 810 can cut the workpiece.

[0204] It should be noted that “when the second positioning mechanism 820 is in the fourth position, the workpiece is arranged relative to the cutter 812 along the fourth direction” means that when the second positioning mechanism 820 is in the fourth position, the position of the workpiece to be cut is arranged relative to the cutter 812.

The detection block 842 has a first abutting surface 8421 and a second abutting surface 8422. Along the fourth direction, the first abutting surface 8421 is higher than the second abutting surface 8422. Along the fifth direction, the first abutting surface 8421 is closer to the second positioning mechanism 820 than the second abutting surface 8422.

[0216] The first over-push detection mechanism 840 is a mechanism for detecting whether the workpiece positioned by the second positioning mechanism 820 is over-pushed. Taking the workpiece as a battery as an example, "over-pushing" means that the second positioning mechanism 820 exceeds the fourth position during the process of moving from the third position to the fourth position along the fifth direction, so that the body of the workpiece is opposite to the cutter 812 along the fourth direction, rather than the air bag being opposite to the cutter 812 along the fourth direction.

[0219] Optionally, the first block and the second block are formed into an "L" shaped structure.

[0220] The sixth driving member 841 is a driving structure for driving the positioning block 842 to move along the fourth direction so that the positioning block 842 approaches or moves away from the second positioning mechanism 820, and the positioning block 842 contacts the workpiece positioned by the second positioning mechanism 820. When the workpiece positioned by the second positioning mechanism 820 is not over-pushed, the first abutting surface 8421 of the positioning block 842 can abut against the workpiece, and the second abutting surface 8422 of the positioning block 842 cannot abut against the workpiece. When the workpiece positioned by the second positioning mechanism 820 is over-pushed, the first abutting surface 8421 of the positioning block 842 cannot abut against the workpiece, and the second abutting surface 8422 of the positioning block 842 can abut against the workpiece.

[0221] The detection unit 843 can be directly electrically connected to the cutting mechanism 810, or can be electrically connected to the cutting mechanism 810 through an intermediate component. For example, the intermediate component can be a controller. The controller is electrically connected to the detection unit 843 and the cutting mechanism 810. When the detection unit 843 detects that the second abutting surface 8422 is in contact with the workpiece, the controller controls the cutting mechanism 810 to prevent cutting the workpiece.

[0222] The detection block 842 is used to detect whether the workpiece positioned by the second positioning mechanism 820 is over-pushed. When the workpiece is not over-pushed, the first abutting surface 8421 can abut against the workpiece, the second abutting surface 8422 does not abut against the workpiece, and the cutter 812 can cut the workpiece normally. When the workpiece is over-pushed, the first abutting surface 8421 cannot abut against the workpiece, and the second abutting surface 8422 abuts against the workpiece. At this time, the cutter 812 should be prevented from cutting the workpiece to reduce the risk of the cutter 812 damaging the workpiece.

[0223] Please refer to Fig. 9 and Fig.10In some embodiments, the detection unit 843 includes a first laser emitter 8431 and a first laser receiver 8432, and the first laser emitter 8431 is arranged opposite to the first laser receiver 8432. The first over-thrust detection mechanism 840 also includes a shielding member 844, which is connected to the position detection block 842, and the shielding member 844 is configured to leave between the first laser emitter 8431 and the first laser receiver 8432 when the second abutting surface 8422 contacts the workpiece, so that the first laser receiver 8432 can receive the laser emitted by the first laser emitter 8431, and the cutting mechanism 810 responds to the first laser receiver 8432.

[0224] The first laser emitter 8431 is used to emit laser light, and the first laser receiver 8432 is used to receive the laser light emitted by the first laser emitter 8431. The first laser emitter 8431 generates a first electrical signal when it is able to receive the laser light emitted by the first laser emitter 8431, and generates a second electrical signal when it is unable to receive the laser light emitted by the first laser emitter 8431, and the first electrical signal and the second electrical signal are different.

[0225] The shielding member 844 is connected to the detection block 842, and can move along the fourth direction driven by the detection block 842. Optionally, the cutting device 800 includes a mounting seat 847, and the mounting seat 847 is connected to the sixth driving member 841. The detection block 842 is movably arranged on the mounting seat 847 along the fourth direction. The mounting seat 847 includes a fifth position and a sixth position, and the sixth driving member 841 is used to drive the mounting seat 847 to switch between the fifth position and the sixth position. When the mounting seat 847 is in the fifth position, the detection block 842 is separated from the workpiece positioned by the second positioning mechanism 820. When the mounting seat 847 is in the sixth position, the first abutment surface 8421 or the second abutment surface 8422 contacts the workpiece positioned by the second positioning mechanism 820.

[0226] In some embodiments, the cutting device 800 includes a guide post 846 , one end of the guide post 846 is connected to the positioning block 842 , the other end of the guide post 846 is connected to the shielding member 844 , and the guide post 846 is passed through the mounting seat 847 .

[0227] When the workpiece positioned by the second positioning mechanism 820 has not been over-pushed, the first abutment surface 8421 of the positioning block 842 contacts the workpiece, and the shielding member 844 blocks the first laser emitter 8431 and the first laser receiver 8432. The first laser receiver 8432 cannot receive the laser emitted by the first laser emitter 8431, and the first laser receiver 8432 generates a second electrical signal. The cutting mechanism 810 responds to the second electrical signal, causing the cutting mechanism 810 to start cutting the workpiece. When the workpiece positioned by the second positioning mechanism 820 is over-pushed, the second abutment surface 8422 of the positioning block 842 contacts the workpiece, and the positioning block 842 moves upward along the fourth direction relative to the mounting seat 847, and drives the shielding member 844 to move upward along the fourth direction, thereby causing the shielding member 844 to leave from between the first laser emitter 8431 and the first laser receiver 8432. The first laser receiver 8432 can receive the laser emitted by the first laser emitter 8431, and the first laser receiver 8432 generates a first electrical signal. The cutting mechanism 810 responds to the first electrical signal to prevent the cutting mechanism 810 from cutting the workpiece.

[0228] When the workpiece is not over-pushed, the first abutting surface 8421 contacts the workpiece, the position of the positioning block 842 will not move upward, and will not drive the shielding member 844 to leave between the first laser emitter 8431 and the first laser receiver 8432. The shielding member 844 blocks the laser emitted by the first laser emitter 8431, so that the first laser receiver 8432 cannot receive the laser emitted by the first laser emitter 8431. When the workpiece is over-pushed, the second abutting surface 8422 contacts the workpiece, the position of the positioning block 842 will move upward, and drive the shielding member 844 to leave between the first laser emitter 8431 and the first laser receiver 8432. The shielding member 844 no longer blocks the laser emitted by the first laser emitter 8431, so that the first laser receiver 8432 can receive the laser emitted by the first laser emitter 8431, and the cutting mechanism 810 responds to the first laser receiver 8432 to prevent the cutter 812 from cutting the workpiece.

[0229] Please refer to Fig. 9 and Fig.10In some embodiments, the cutting device 800 further includes an elastic element 845, which is disposed between the mounting seat 847 and the detection block 842. Optionally, the elastic element 845 is a spring, which is sleeved on the guide column 846, one end of the spring abuts against the mounting seat 847, and the other end of the spring abuts against the detection block 842. By arranging the elastic element 845 between the mounting seat 847 and the detection block 842, the detection block 842 can only overcome the elastic force of the elastic element 845 and move upward when the workpiece positioned by the second positioning mechanism 820 is over-pushed, thereby reducing the risk of misjudgment of the detection block 842 caused by other factors, reducing the risk of misjudgment of the first over-pushing detection mechanism 840, and improving the accuracy of the detection by the first over-pushing detection mechanism 840. In addition, under the elastic force of the elastic element 845, the detection block 842 can also play a role in assisting the positioning of the workpiece, so that the workpiece that has not been over-pushed is less likely to shift during the cutting process.

[0230] Please refer to Fig. 9 and Fig.10 In some embodiments, the cutting device 800 includes a second over-push detection mechanism 850 and a first alarm. The second over-push detection mechanism 850 is used to detect the position of the workpiece positioned by the second positioning mechanism 820. The first alarm responds to the second over-push detection mechanism 850.

[0231] The second over-push detection mechanism 850 is also a mechanism for detecting whether the workpiece positioned by the second positioning mechanism 820 is over-pushed. The first over-push detection mechanism 840 and the second over-push detection mechanism 850 cooperate to achieve double detection.

[0232] The first alarm is a product that reminds or warns the staff to take certain actions in the form of sound, light, air pressure, etc., in order to prevent or prevent the consequences of a certain event. The first alarm can be directly electrically connected to the second over-push detection mechanism 850, or it can be electrically connected to the second over-push detection mechanism 850 through an intermediate component. For example, the intermediate component can be a controller. The controller is electrically connected to the first alarm and the second over-push detection mechanism 850. When the second over-push detection mechanism 850 detects that the workpiece is over-push, the controller controls the first alarm to alarm.

[0233] The second over-pushing detection mechanism 850 can detect whether the workpiece is over-pushed. When the workpiece is not over-pushed, the first alarm does not sound an alarm. When the workpiece is over-pushed, the first alarm sounds an alarm, thereby reducing the risk of the cutter 812 damaging the workpiece.

[0234] Please refer to Fig. 9 and Fig.10In some embodiments, the second over-thrust detection mechanism 850 includes a second laser emitter 851 and a second laser receiver 852, and the second laser emitter 851 is arranged opposite to the second laser receiver 852. The second laser receiver 852 is used to receive the laser emitted by the second laser emitter 851, and the first alarm responds to the second laser receiver 852.

[0235] The second laser emitter 851 is used to emit laser light, and the second laser receiver 852 is used to receive the laser light emitted by the second laser emitter 851. The second laser emitter 851 generates a third electrical signal when it is able to receive the laser light emitted by the second laser emitter 851, and generates a fourth electrical signal when it is unable to receive the laser light emitted by the second laser emitter 851, and the third electrical signal and the fourth electrical signal are different.

[0236] When the workpiece positioned by the second positioning mechanism 820 is not over-pushed, the workpiece positioned by the second positioning mechanism 820 will not block the laser emitted by the second laser emitter 851, the second laser receiver 852 can receive the laser emitted by the second laser emitter 851, the second laser receiver 852 generates a third electrical signal, and the first alarm responds to the third electrical signal without sounding an alarm. When the workpiece positioned by the second positioning mechanism 820 is over-pushed, the workpiece positioned by the second positioning mechanism 820 will block the laser emitted by the second laser emitter 851, the second laser receiver 852 cannot receive the laser emitted by the second laser emitter 851, the second laser receiver 852 generates a fourth electrical signal, and the first alarm responds to the fourth electrical signal and sounds an alarm.

[0237] When the workpiece is not over-pushed, the second laser receiver 852 can receive the laser emitted by the second laser emitter 851. When the workpiece is over-pushed, the workpiece will block the laser emitted by the second laser emitter 851. At this time, the second laser receiver 852 cannot receive the laser emitted by the second laser emitter 851, and the first alarm sounds.

[0238] Please refer to Fig.11 and Fig.12 , Fig.11 A schematic diagram of the structure of a picking mechanism 910 provided in some embodiments of the present application. Fig.12 for Fig.11 The transfer mechanism 900 includes a multi-axis manipulator 911, a suction member 912 and a clamping member 913, and the suction member 912 and the clamping member 913 are both arranged at the output end of the multi-axis manipulator 911. The suction member 912 is used to suction the workpiece, and the clamping member 913 is used to clamp the workpiece.

[0239] The adsorbing member 912 is a structure for adsorbing a workpiece. For example, the adsorbing member 912 may be a magnet. For another example, the adsorbing member 912 may be a suction cup.

[0240] The clamping member 913 is a structure for clamping a workpiece and includes at least two clamping jaws, which cooperate to clamp the workpiece.

[0241] The suction member 912 and the clamping member 913 are both arranged at the output end of the multi-axis manipulator 911. When the transfer mechanism 900 transfers the workpiece, the suction member 912 and the clamping member 913 act on the workpiece at the same time to transfer the workpiece together.

[0242] When the multi-axis manipulator 911 picks up a workpiece, the suction member 912 can suction the workpiece, and the clamping member 913 can clamp the workpiece, which helps to reduce the risk of the workpiece falling.

[0243] Please refer to Fig.13 , Fig.13 A schematic diagram of the structure of a waste box 940 provided for some embodiments of the present application. In some embodiments, the packaging device 20 includes a waste box 940, which is used to accommodate workpieces. The waste box 940 includes a box body 941 and a partition 942, and one end of the box body 941 along the sixth direction has a fourth opening 943 for the workpiece to enter. A plurality of slots 9411 are provided on the inner wall of the box body 941, and the plurality of slots 9411 are arranged along the seventh direction. The plurality of slots 9411 are selectively matched with the partition 942, and the sixth direction intersects with the seventh direction.

[0244] Please refer to Fig.13 , the sixth direction is the H direction shown in the figure, and the seventh direction is the I direction shown in the figure. The angle between the sixth direction and the seventh direction can be an acute angle or a right angle. Please refer to Fig.12 and Fig.13 , in the figure, the sixth direction and the seventh direction are perpendicular.

[0245] Optionally, the third direction, the lifting direction of the lifting mechanism 730, the fourth direction and the sixth direction are all the same, that is, Figure 6 The Z direction shown in Figure 8 The C direction shown in is the same direction. Fig. 9 The D direction and Fig.13 The H direction shown is the same.

[0246] The waste box 940 is a structure for accommodating workpieces that do not meet the requirements. For example, when the weighing result of the weighing device 700 on the workpiece does not meet the requirements, the transfer mechanism 900 can transfer the workpiece that does not meet the requirements to the waste box 940 in response to the weighing device 700.

[0247] The box body 941 is the main structure of the waste box 940, which is mainly used to realize the storage function of the waste box 940. The waste box 940 has a fourth opening 943 at one end along the sixth direction, and the fourth opening 943 is used for the workpiece to enter or leave the waste box 940. A plurality of slots 9411 are provided on the inner wall of the box body 941, and the plurality of slots 9411 are arranged at intervals along the seventh direction.

[0248] The partition 942 is used to be inserted into the slot 9411. When the partition 942 is inserted into different slots 9411, the size of the space divided in the box body 941 is also different to adapt to the size of the workpiece. Therefore, the partition 942 can be selected to be inserted into the appropriate slot 9411 according to the size of the workpiece.

[0249] By setting a plurality of slots 9411 on the inner wall of the box body 941, the partition 942 is inserted into the appropriate slot 9411 according to the different workpiece models, so that the isolated space matches the size of the workpiece, thereby improving the adaptability of the waste box 940 to different types of workpieces.

[0250] Please refer to Fig.13 In some embodiments, the packaging device 20 includes a material level detection mechanism 944 and a second alarm. Along the sixth direction, the material level detection mechanism 944 is used to detect the material level of the workpiece in the waste box 940. The second alarm responds to the material level detection mechanism 944.

[0251] The material level detection mechanism 944 is a detection structure for detecting the material level of the workpieces in the waste box 940. When the material level of the workpieces in the waste box 940 reaches a threshold value, the second alarm sounds an alarm, thereby reminding the staff to handle it.

[0252] Optionally, the material level detection mechanism 944 includes a third laser transmitter 9441 and a third laser receiver 9442, and the third laser transmitter 9441 is arranged opposite to the third laser receiver 9442. The third laser receiver 9442 is used to receive the laser emitted by the third laser transmitter 9441, and the second alarm responds to the third laser receiver 9442.

[0253] The third laser emitter 9441 is used to emit laser light, and the third laser receiver 9442 is used to receive the laser light emitted by the third laser emitter 9441. The third laser emitter 9441 generates a fifth electrical signal when it is able to receive the laser light emitted by the third laser emitter 9441, and generates a sixth electrical signal when it is unable to receive the laser light emitted by the third laser emitter 9441, and the fifth electrical signal and the sixth electrical signal are different.

[0254] When the material level of the workpiece in the waste box 940 does not reach the threshold value, the workpiece will not block the laser emitted by the third laser emitter 9441, the third laser receiver 9442 can receive the laser emitted by the third laser emitter 9441, the third laser receiver 9442 generates a fifth electrical signal, and the second alarm responds to the fifth electrical signal without sounding an alarm. When the material level of the workpiece in the waste box 940 does not reach the threshold value, the workpiece will block the laser emitted by the third laser emitter 9441, the third laser receiver 9442 cannot receive the laser emitted by the third laser emitter 9441, the third laser receiver 9442 generates a sixth electrical signal, and the second alarm responds to the sixth electrical signal and sounds an alarm.

[0255] By setting up the material level detection mechanism 944, the material level detection mechanism 944 can detect the material level of the workpieces in the waste box 940. When the material level of the workpieces in the waste box 940 reaches a threshold value, the second alarm sounds an alarm to remind the staff to handle it.

[0256] Please refer to Fig.13 In some embodiments, the waste box 940 is slidably disposed on the frame, and the waste box 940 has a working position and a discharge position. The waste box 940 can slide relative to the frame to switch between the working position and the discharge position. The packaging device 20 also includes an in-place detection mechanism 945, which is used to detect whether the waste box 940 has reached the working position. By setting the in-place detection mechanism 945 to detect whether the waste box 940 has reached the working position, the accuracy of the transfer mechanism 900 transferring the workpiece to the waste box 940 is improved.

[0257] The in-position detection mechanism 945 can be an in-position switch, a laser beam sensor, etc.

[0258] Please refer to Fig.14 , Fig.14 A schematic diagram of the structure of a feeding mechanism 920 provided in some embodiments of the present application. In some embodiments, the transfer mechanism 900 includes a feeding mechanism 920 and a lifting mechanism 960, wherein the feeding mechanism 920 is used to transport the silo 950 to the top of the lifting mechanism 960, and the lifting mechanism 960 is used to lift a stack of workpieces in the silo 950, so that the top workpiece in the stack is located at the discharge port of the silo 950, so as to facilitate the picking mechanism 910 to pick up.

[0259] Optionally, the feeding mechanism 920 may be a conveyor belt mechanism, a pull belt mechanism, etc.

[0260] In some embodiments, the size of the silo 950 can be adjusted to accommodate workpieces of different sizes.

[0261] Please refer to Fig.15 , Fig.15This is a schematic block diagram of a packaging method 30 provided in some embodiments of the present application. The present application also provides a packaging method 30, which is based on the packaging device 20 described above, and includes:

[0262] Step S1: weighing the workpiece once by the weighing device 700;

[0263] Step S2: Puncture, evacuate and package the workpiece that meets the one-time weighing requirement by the packaging device 10;

[0264] Step S3: performing secondary weighing on the packaged workpiece by means of the weighing device 700;

[0265] Step S4: cutting the workpieces that meet the secondary weighing requirements by the cutting device 800.

[0266] According to some embodiments of this application, please refer to Figure 1 to Figure 7 .

[0267] The embodiment of the present application provides a packaging device 10, which includes a first shell 100, a first positioning mechanism 200, a puncturing mechanism 300, a negative pressure mechanism 400 and a heat sealing mechanism 500. The first shell 100 has a receiving cavity 110. The first positioning mechanism 200 is connected to the first shell 100, and the first positioning mechanism 200 is used to position the workpiece and transfer the workpiece into the receiving cavity 110. The puncturing mechanism 300 is connected to the first shell 100, and the puncturing mechanism 300 is used to puncture the workpiece located in the receiving cavity 110. The negative pressure mechanism 400 is in communication with the receiving cavity 110, and the negative pressure mechanism 400 is used to extract negative pressure for the receiving cavity 110. The heat sealing mechanism 500 is connected to the first shell 100, and the heat sealing mechanism 500 is used to heat-seal the workpiece punctured by the puncturing mechanism 300. The first positioning mechanism 200 of the packaging device 10 can position the workpiece and transfer the workpiece from outside the accommodating cavity 110 to inside the accommodating cavity 110. The puncturing mechanism 300 can puncture the workpiece located in the accommodating cavity 110 to release the gas in the workpiece. The negative pressure mechanism 400 can draw negative pressure to the accommodating cavity 110, thereby extracting the gas in the punctured workpiece. The heat sealing mechanism 500 can heat-seal the punctured workpiece again. The packaging device 10 can automatically complete the puncturing, exhaustion and packaging of the workpiece with high efficiency and good quality.

[0268] The accommodating chamber 110 has a first opening 111. The first positioning mechanism 200 includes a movable component 210, and the movable component 210 has a first position and a second position. The movable component 210 includes a support member 212 and a blocking member 211, and the support member 212 is used to support the workpiece, and the support member 212 is connected to the blocking member 211. When the movable component 210 is located at the first position, the support member 212 is located outside the accommodating chamber 110, and the blocking member 211 opens the first opening 111. When the movable component 210 is located at the second position, the support member 212 is located inside the accommodating chamber 110, and the blocking member 211 blocks the first opening 111. In the process of the movable component 210 transferring the workpiece from outside the accommodating chamber 110 to inside the accommodating chamber 110, the blocking member 211 will gradually block the first opening 111. In this way, the action of transferring the workpiece into the accommodating chamber 110 and the action of blocking the first opening 111 are combined into one action, which is conducive to reducing the action time and improving efficiency. Similarly, when the movable assembly 210 transfers the workpiece from the accommodating cavity 110 to the outside of the accommodating cavity 110, the blocking member 211 gradually opens the first opening 111. In this way, the action of transferring the workpiece to the outside of the accommodating cavity 110 and the action of opening the first opening 111 are combined into one action, which is conducive to reducing the action time and improving efficiency.

[0269] The piercing mechanism 300 includes a bayonet assembly 310 and a third driving member 320, wherein the bayonet assembly 310 is located in the accommodating chamber 110, and the third driving member 320 connects the first housing 100 and the bayonet assembly 310, and the third driving member 320 is used to drive the bayonet assembly 310 to move along the third direction to pierce the workpiece. The third driving member 320 can drive the bayonet assembly 310 to move along the third direction so as to adjust the position of the bayonet assembly 310, thereby piercing the workpiece. In this way, for workpieces of different models, the bayonet assembly 310 can be adjusted to different positions for piercing, thereby improving the adaptability of the packaging device 10 to workpieces of different models.

[0270] The embodiment of the present application further provides a packaging device 20, which includes the packaging device 10, a weighing device 700, a cutting device 800 and a transfer mechanism 900. The weighing device 700 is used to weigh the workpiece, and the cutting device 800 is used to cut the workpiece. The transfer mechanism 900 is used to switch the workpiece between the packaging device 10, the weighing device 700 and the cutting device 800.

[0271] The weighing device 700 includes a tray 710, a weighing mechanism 720 and a lifting mechanism 730. The tray 710 is used to support the workpiece, and the weighing mechanism 720 is arranged below the tray 710. The lifting mechanism 730 includes a movable member 731 that can move along the lifting direction of the lifting mechanism 730. The tray 710 is movably arranged on the movable member 731 along the lifting direction. A limiting member 732 is arranged on the movable member 731. The limiting member 732 is used to support the tray 710 and drive the tray 710 to rise when the movable member 731 rises. The limiting member 732 is also used to separate from the tray 710 when the movable member 731 falls, so that the tray 710 falls on the weighing mechanism 720, so that the weighing mechanism 720 weighs the workpiece and the tray 710. The tray 710 can support the workpiece, and the workpiece will not directly contact the weighing mechanism 720, which reduces the risk of the workpiece damaging the weighing mechanism 720 and is conducive to extending the life of the weighing mechanism 720. The tray 710 is movably arranged on the movable member 731. When the movable member 731 rises, the stopper 732 on the movable member 731 can contact the tray 710 and drive the tray 710 to rise, so that the tray 710 can receive the workpiece provided by the transfer mechanism 900. When the movable member 731 descends, the tray 710 descends accordingly until the tray 710 falls on the weighing mechanism 720, and the stopper 732 is separated from the tray 710. In this way, the lifting mechanism 730 will not affect the weighing of the weighing mechanism 720, and the weighing mechanism 720 can weigh the tray 710 and the workpiece as a whole, thereby obtaining the weight of the workpiece, so as to judge whether the workpiece meets the requirements.

[0272] The cutting device 800 includes a cutting mechanism 810 and a second positioning mechanism 820, wherein the cutting mechanism 810 includes a cutter 812 moving along a fourth direction, and the cutter 812 is used to cut a workpiece. The second positioning mechanism 820 is used to position the workpiece, and the second positioning mechanism 820 has a third position and a fourth position. The second positioning mechanism 820 can move along a fifth direction to switch between the third position and the fourth position. When the second positioning mechanism 820 is in the third position, the second positioning mechanism 820 receives the workpiece provided by the transfer mechanism 900. When the second positioning mechanism 820 is in the fourth position, the workpiece is arranged relative to the cutter 812 along the fourth direction, and the fourth direction intersects with the fifth direction. When the second positioning mechanism 820 is in the third position, the second positioning mechanism 820 can receive the workpiece provided by the transfer mechanism 900. When the second positioning mechanism 820 is in the fourth position, the workpiece is arranged relative to the cutter 812 along the fourth direction, so that the cutter 812 cuts the workpiece. After the workpiece is cut, the second positioning mechanism 820 can return to the third position to facilitate sending out the cut workpiece and receiving a new workpiece to be cut.

[0273] The cutting device 800 includes a first over-push detection mechanism 840, which includes a detection block 842, a sixth driving member 841 and a detection unit 843. The detection block 842 has a first abutting surface 8421 and a second abutting surface 8422. Along the fourth direction, the first abutting surface 8421 is higher than the second abutting surface 8422. Along the fifth direction, the first abutting surface 8421 is closer to the second positioning mechanism 820 than the second abutting surface 8422. The sixth driving member 841 is connected to the detection block 842, and the sixth driving member 841 is used to drive the detection block 842 to approach or move away from the second positioning mechanism 820 along the fourth direction. The detection unit 843 is electrically connected to the cutting mechanism 810, and when the detection unit 843 detects that the second abutting surface 8422 is in contact with the workpiece, the cutter 812 is prevented from cutting the workpiece. The detection block 842 is used to detect whether the workpiece positioned by the second positioning mechanism 820 is over-pushed. When the workpiece is not over-pushed, the first abutting surface 8421 can abut against the workpiece, the second abutting surface 8422 does not abut against the workpiece, and the cutter 812 can cut the workpiece normally. When the workpiece is over-pushed, the first abutting surface 8421 cannot abut against the workpiece, and the second abutting surface 8422 abuts against the workpiece. At this time, the cutter 812 should be prevented from cutting the workpiece to reduce the risk of the cutter 812 damaging the workpiece.

[0274] The detection unit 843 includes a first laser emitter 8431 and a first laser receiver 8432, and the first laser emitter 8431 is arranged opposite to the first laser receiver 8432. The first over-thrust detection mechanism 840 also includes a shielding member 844, which is connected to the position detection block 842, and the shielding member 844 is configured to leave between the first laser emitter 8431 and the first laser receiver 8432 when the second abutting surface 8422 contacts the workpiece, so that the first laser receiver 8432 can receive the laser emitted by the first laser emitter 8431. The cutting mechanism 810 responds to the first laser receiver 8432. When the workpiece is not over-pushed, the first abutting surface 8421 contacts the workpiece, the position of the positioning block 842 will not move upward, and will not drive the shielding member 844 to leave between the first laser emitter 8431 and the first laser receiver 8432. The shielding member 844 blocks the laser emitted by the first laser emitter 8431, so that the first laser receiver 8432 cannot receive the laser emitted by the first laser emitter 8431. When the workpiece is over-pushed, the second abutting surface 8422 contacts the workpiece, the position of the positioning block 842 will move upward, and drive the shielding member 844 to leave between the first laser emitter 8431 and the first laser receiver 8432. The shielding member 844 no longer blocks the laser emitted by the first laser emitter 8431, so that the first laser receiver 8432 can receive the laser emitted by the first laser emitter 8431, and the cutting mechanism 810 responds to the first laser receiver 8432 to prevent the cutter 812 from cutting the workpiece.
