Description

Technical Field

[0001] This invention relates to the field of battery production equipment technology, and in particular to a flat-lying puncture, vacuuming and packaging integrated machine and a battery processing equipment that is easy to maintain. Background Technology

[0002] During battery production, varying amounts of gas are generated during the battery formation process. When the soft-pack battery cells flow to the next process after formation, this gas can backflow into the cell, severely affecting its performance. Therefore, after initial sealing with electrolyte filling, the battery needs to undergo puncture, degassing, and resealing operations sequentially to ensure no gas remains inside. Patent application number 201821437211.1 discloses a battery packaging device. While it describes processing flat batteries, the gas bag portion of the battery is suspended during feeding, making it prone to drooping and bending, which can affect subsequent puncture, degassing, and resealing processes. This makes it difficult to guarantee the quality of battery processing. Furthermore, the packaging and pressing devices are located inside the main body of the casing, which is cramped, making maintenance difficult and increasing maintenance complexity. Therefore, the device has significant drawbacks, necessitating a solution. Summary of the Invention

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A horizontally oriented integrated puncture, vacuuming, and sealing machine includes a frame, a lower cavity mounted on the frame, an upper cover plate covering the top opening of the lower cavity, a feeding drive mechanism mounted on the frame, a side cover plate connected to the moving end of the feeding drive mechanism, a frame connected to the inner side of the side cover plate, a material fixing mechanism mounted on the frame, a puncture base plate mounted on the frame and located in front of the material fixing mechanism, a puncture knife assembly lifted and lowered on the bottom surface of the upper cover plate, an upper sealing head assembly disposed on one side of the puncture knife assembly, a pressure plate disposed on one side of the upper sealing head assembly, a lower sealing head assembly lifted and lowered in the lower cavity, a lower sealing drive mechanism mounted at the bottom of the lower cavity, an opening and closing drive mechanism connecting the upper cover plate and the lower cavity, a gas-liquid separation vacuuming device mounted in the lower cavity, and an upper sealing drive mechanism and a puncture drive mechanism respectively mounted on the top surface of the upper cover plate. The system includes a downward pressure drive mechanism, an upper sealing drive mechanism connected to the upper sealing head assembly, a piercing drive mechanism connected to the piercing knife assembly, a downward pressure drive mechanism connected to the pressure plate, and a lower sealing drive mechanism connected to the lower sealing head assembly. A sealing space is provided between the piercing base plate and the material-fixing mechanism. A vacuum chamber is provided inside the piercing base plate. Multiple piercing holes are provided on the top surface of the piercing base plate, and an air extraction hole is provided on the bottom surface. The air extraction hole and the multiple piercing holes are connected to the vacuum chamber. A gas-liquid separation vacuum device is detachably connected to the air extraction hole. The feeding drive mechanism drives the side cover plate to approach or move away from the side opening of the lower cavity. The side cover plate is used to close the side opening of the lower cavity. When the frame is located in the lower cavity, the piercing knife assembly is correspondingly positioned with the piercing base plate, and the upper sealing head assembly, sealing space, and lower sealing head assembly are correspondingly positioned. The pressure plate is located above the material-fixing mechanism.

[0006] Furthermore, the bottom surface of the upper cover is equipped with two guide frames. One end of the piercing knife assembly is detachably and slidably connected to one guide frame, while the other end of the piercing knife assembly is rotatably and slidably connected to the other guide frame.

[0007] Furthermore, the upper cover plate is provided with a pressure relief hole, and the upper cover plate is equipped with an opening and closing mechanism for opening or closing the pressure relief hole.

[0008] Furthermore, a top plate is installed in the lower cavity, which is positioned opposite to the pressure plate. An upper drive mechanism is installed on the bottom surface of the lower cavity, and the upper drive mechanism is connected to the top plate.

[0009] Furthermore, the gas-liquid separation vacuum device is detachably and sealed to the air extraction port via a docking mechanism; the docking mechanism includes a pipe joint installed on the frame or piercing the bottom plate and communicating with the air extraction port, a lifting plate that is lifted and lowered in the lower cavity, a connecting pipe installed on the lifting plate and detachably and sealed to the pipe joint, and a docking drive mechanism installed in the lower cavity. The docking drive mechanism is driven to the lifting plate, and the connecting pipe is communicated with the gas-liquid separation vacuum device.

[0010] Furthermore, the inner wall of the lower cavity is equipped with a slot plate, and the side wall of the frame is equipped with a locking element, which engages with the slot plate.

[0011] Furthermore, the bottom wall of the vacuum chamber is provided with a guide slope, the slope of which is inclined toward the direction of the air extraction hole.

[0012] Furthermore, the material positioning mechanism includes a suction plate mounted on the frame, a baffle mounted on the front side of the suction plate, a positioning plate movably mounted on the rear side of the suction plate, and a positioning driver mounted on the outside of the side cover plate. The positioning driver is driven to connect with the positioning plate and is used to drive the positioning plate to move closer to or away from the baffle. The top surface of the suction plate is provided with multiple suction holes, and the inside of the suction plate is provided with a suction channel. The multiple suction holes are all connected to the suction channel, and the suction channel is connected to a vacuum alarm. The sealing space is located between the puncture base plate and the baffle.

[0013] The present invention also provides a battery processing equipment that is easy to maintain, characterized in that: it includes a machine base and the above-mentioned flat-lying puncture, vacuuming and packaging integrated machine, wherein the flat-lying puncture, vacuuming and packaging integrated machine is slidably connected to the machine base.

[0014] Furthermore, there are multiple horizontal puncture, vacuuming and packaging integrated machines, which are arranged in a row inside the machine.

[0015] The beneficial effects of this invention are as follows: In practical applications, the battery is placed flat on the feeding mechanism, which positions the battery body. The air bag portion of the battery protrudes outside the feeding mechanism, and the piercing bottom plate supports the air bag portion, preventing it from sagging or bending. The feeding drive mechanism drives the side cover plate and frame to move towards the lower cavity until the frame enters the lower cavity through the side opening. The side cover plate then closes the side opening of the lower cavity, sealing the connection between the side cover plate and the side opening. At this time, the piercing knife assembly is positioned above the air bag portion supported by the piercing bottom plate. The upper and lower sealing head assemblies are located above and below the air bag portion and the encapsulation space, respectively. The pressure plate is positioned above the battery body positioned by the feeding mechanism. The gas-liquid separation vacuum device is connected to the suction port. The downward pressure drive mechanism drives the pressure plate to press down on the battery body, and the piercing drive mechanism drives the piercing knife assembly to move downward, allowing the piercing knife assembly to engage with the multiple piercing holes of the piercing bottom plate to pierce the air bag. The gas-liquid separation vacuum device evacuates the punctured gas bag section and lower cavity of the battery through the air extraction port, vacuum chamber, and multiple puncture holes. Under the action of the pressure plate and vacuuming, the gas inside the battery body is extracted into the vacuum chamber. The gas will be mixed with a small amount of electrolyte. The gas and electrolyte are drawn into the vacuum chamber and discharged through the air extraction port. The gas-liquid separation vacuum device can separate the gas and electrolyte, avoiding electrolyte pollution of the environment and / or damage to the gas-liquid separation vacuum device. After the battery is vacuumed, the upper sealing drive mechanism drives the upper sealing head assembly to move down, and the lower sealing drive mechanism drives the lower sealing head assembly to move up, so that the upper sealing head assembly and the lower sealing head assembly are close to each other until the upper sealing head assembly and the lower sealing head assembly protrude into the sealing space to seal the gas bag section, thus completing the puncture, vacuuming and sealing of the flat battery. The feeding drive mechanism drives the side cover and frame and other structures to move away from the lower cavity to realize the discharge of the processed battery, which is convenient for battery replacement. When the machine needs to be disassembled or maintained, the opening and closing drive mechanism drives the upper cover and lower cavity to open, allowing the upper end cap assembly and piercing knife assembly to move out of the lower cavity and be exposed. Depending on the actual maintenance needs, the piercing knife assembly can also be moved downwards via the piercing drive mechanism, or the upper end cap assembly can be moved downwards via the upper sealing drive mechanism, causing the upper end cap assembly and piercing knife assembly to be misaligned. This facilitates maintenance personnel in maintaining and disassembling the upper end cap assembly, piercing knife assembly, and the lower end cap assembly within the lower cavity. This horizontal piercing, vacuuming, and sealing integrated machine enables the piercing, vacuuming, and sealing of horizontally lying batteries. The piercing base plate and the material-setting mechanism are integrated into the frame. The piercing base plate supports the air bag portion of the battery, improving the stability of battery transport and preventing the air bag portion from sagging and bending, which would affect subsequent piercing, vacuuming, and sealing processes, thus improving processing quality. Furthermore, the automatic opening and closing of the upper cover and lower cavity not only facilitates machine maintenance but also reduces the difficulty and labor intensity of maintenance.This easy-to-maintain battery processing equipment features a horizontal puncture, vacuuming, and encapsulation integrated machine that can be pulled out of the machine platform for easy maintenance. It is simple and convenient to operate. Attached Figure Description

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figures 1 to 6 As shown, the present invention provides a flat-lying piercing, vacuuming, and packaging integrated machine, which includes a frame 1, a lower cavity 2 mounted on the frame 1, an upper cover plate 3 covering the top opening of the lower cavity 2, a feeding drive mechanism 4 mounted on the frame 1, a side cover plate 5 connected to the moving end of the feeding drive mechanism 4, a frame 6 connected to the inner side of the side cover plate 5, a material fixing mechanism 7 mounted on the frame 6, a piercing bottom plate 8 mounted on the frame 6 and located in front of the material fixing mechanism 7, a piercing knife assembly 9 lifted and disposed on the bottom surface of the upper cover plate 3, and a piercing knife assembly 9 disposed on the bottom surface of the upper cover plate 3. The system includes an upper sealing head assembly 10 on one side, a pressure plate 11 on one side of the upper sealing head assembly 10, a lower sealing head assembly 12 that is lifted and lowered within the lower cavity 2, a lower sealing drive mechanism 13 installed at the bottom of the lower cavity 2, an opening and closing drive mechanism 14 connecting the upper cover plate 3 and the lower cavity 2, a gas-liquid separation vacuum device 15 installed in the lower cavity 2, and an upper sealing drive mechanism 16, a puncture drive mechanism 17, and a lower pressing drive mechanism 18 respectively installed on the top surface of the upper cover plate 3. The upper sealing drive mechanism 16 is drivenly connected to the upper sealing head assembly 10, and the puncture drive mechanism 17... The piercing blade assembly 9 is driven and connected to the pressing drive mechanism 18 and the pressure plate 11. The lower sealing drive mechanism 13 and the lower sealing head assembly 12 are driven and connected to each other. A sealing space 19 is provided between the piercing base plate 8 and the material fixing mechanism 7. A vacuum chamber is provided inside the piercing base plate 8. Multiple piercing holes 20 are provided on the top surface of the piercing base plate 8. An air extraction hole is provided on the bottom surface of the piercing base plate 8. The air extraction hole and the multiple piercing holes 20 are respectively connected to the vacuum chamber. The gas-liquid separation vacuum device 15 is detachably connected to the air extraction hole. The feeding drive mechanism 4 drives the side cover plate 5 to approach. Or away from the side opening of the lower cavity 2; the side cover plate 5 is used to cover the side opening of the lower cavity 2; when the frame 6 is located in the lower cavity 2, the piercing knife assembly 9 is correspondingly set with the piercing base plate 8, the upper end cap assembly 10, the encapsulation space 19 and the lower end cap assembly 12 are correspondingly set, and the pressure plate 11 is located above the material setting mechanism 7; the side cover plate 5 is detachably and sealingly connected to the side opening of the lower cavity 2 via the side sealing structure, and the upper cover plate 3 is detachably and sealingly connected to the top opening of the lower cavity 2 via the upper sealing structure. Both the side sealing structure and the upper sealing structure can be sealed with a sealing ring.

[0026] In practical applications, the battery is placed flat on the feeding mechanism 7, which positions the battery body. The air bag portion of the battery protrudes outside the feeding mechanism 7 and pierces the bottom plate 8 to support the air bag portion, preventing it from sagging or bending. The feeding drive mechanism 4 drives the side cover plate 5, along with the frame 6 and other structures, to move towards the lower cavity 2 until the frame 6 enters the lower cavity 2 through the side opening. The side cover plate 5 then closes the side opening of the lower cavity 2, creating a sealed connection between the side cover plate 5 and the side opening of the lower cavity 2. At this time, the piercing knife assembly 9 is located above the air bag portion supported by the piercing base plate 8. The upper end cap assembly 10 and the lower end cap assembly 12 are located above and below the air bag portion and the encapsulation space 19, respectively. The pressure plate 11 is located above the battery body positioned by the material fixing mechanism 7. The gas-liquid separation vacuum device 15 is connected to the air extraction hole. At this time, the downward pressure drive mechanism 18 drives the pressure plate 11 to press down on the battery body, and the piercing drive mechanism 17 drives the piercing knife assembly 9 to move downward, so that the piercing knife assembly 9 cooperates with the multiple piercing holes 20 of the piercing base plate 8 to pierce the air bag. In the battery's gas bag section, the gas-liquid separation vacuum device 15 evacuates the punctured gas bag section and lower cavity 2 through the air extraction port, vacuum chamber, and multiple puncture holes 20. Under the action of the pressure plate 11 and the vacuuming, the gas inside the battery body is extracted into the vacuum chamber. The gas may contain a small amount of electrolyte, causing both gas and electrolyte to be drawn into the vacuum chamber and discharged through the air extraction port. The gas-liquid separation vacuum device 15 can separate the gas and electrolyte, preventing electrolyte from polluting the environment and / or damaging the gas-liquid separation vacuum device 15. After the battery is evacuated, the upper sealing drive mechanism 16 drives the upper sealing head assembly 10 to move downward, and the lower sealing drive mechanism 13 drives the lower sealing head assembly 12 to move upward, so that the upper sealing head assembly 10 and the lower sealing head assembly 12 approach each other until the upper sealing head assembly 10 and the lower sealing head assembly 12 protrude into the encapsulation space 19 to encapsulate the air bag part, so as to complete the puncture, vacuuming and encapsulation of the flat battery. The feeding drive mechanism 4 drives the side cover and frame 6 and other structures to move away from the lower cavity 2 so as to discharge the processed battery and facilitate battery replacement. When the machine needs to be disassembled or maintained, the opening and closing drive mechanism 14 drives the upper cover plate 3 and the lower cavity 2 to open, so that the upper end cap assembly 10 and the piercing knife assembly 9 move out of the lower cavity 2 and are exposed. Depending on the actual maintenance situation, the piercing knife assembly 9 can also be driven down by the piercing drive mechanism 17 or the upper end cap assembly 10 can be driven down by the upper sealing drive mechanism 16, so that the upper end cap assembly 10 and the piercing knife assembly 9 are misaligned, which makes it easier for maintenance personnel to maintain and disassemble the upper end cap assembly 10, the piercing knife assembly 9 and the lower end cap assembly 12 in the lower cavity 2.This flat-lying puncture, vacuuming, and packaging integrated machine enables the puncture, vacuuming, and packaging of flat-lying batteries. The puncture base plate 8 and the material-fixing mechanism 7 are integrated on the frame 6. The puncture base plate 8 supports the air bag part of the battery, improving the stability of battery transportation and preventing the air bag part from sagging and bending, which would affect subsequent puncture, vacuuming, and packaging processes, thus improving the processing quality. It can also automatically open and close the upper cover plate 3 and the lower cavity 2, which not only facilitates maintenance personnel in maintaining the machine but also reduces the difficulty and labor intensity of maintenance.

[0027] In this embodiment, two guide frames 22 are installed on the bottom surface of the upper cover plate 3. One end of the piercing knife assembly 9 is detachably and slidably connected to one guide frame 22, and the other end of the piercing knife assembly 9 is rotatably and slidably connected to the other guide frame 22. The piercing drive mechanism 17 drives the piercing knife assembly 9 to rise and fall, so that both ends of the piercing knife assembly 9 slide up and down along the two guide frames 22 respectively, improving the stability of the piercing knife assembly 9. When it is necessary to disassemble or maintain the piercing knife assembly 9 and / or the upper end cap assembly 10, one end of the piercing knife assembly 9 is detached from the corresponding guide frame 22, so that the piercing knife assembly 9 can rotate outward around the other guide frame 22, thereby making the piercing knife assembly 9 and the upper end cap assembly 10 fully exposed. There is sufficient maintenance space between the piercing knife assembly 9 and the upper end cap assembly 10, which further facilitates maintenance personnel to maintain the piercing knife assembly 9 and the upper end cap assembly 10.

[0028] In this embodiment, the upper cover plate 3 is provided with a pressure relief hole 23, and the upper cover plate 3 is equipped with an opening and closing mechanism 24, which is used to open or close the pressure relief hole 23. After the battery in the lower cavity 2 is processed, the opening and closing mechanism 24 opens the pressure relief hole 23 to break the vacuum in the lower cavity 2. When it is necessary to evacuate the lower cavity 2, the opening and closing mechanism 24 closes the pressure relief hole 23 to prevent vacuum leakage.

[0029] Specifically, the opening and closing mechanism 24 includes a cylinder installed on the top surface of the upper cover plate 3 and a plug installed on the piston rod of the cylinder. The cylinder drives the plug to open or close the pressure relief hole 23.

[0030] In this embodiment, a top plate is vertically mounted inside the lower cavity 2, and the top plate is positioned opposite to the pressure plate 11. An upper push drive mechanism 26 is installed on the bottom surface of the lower cavity 2, and the upper push drive mechanism 26 is drivenly connected to the top plate. When the pressure plate 11 presses down on the battery body, the upper push drive mechanism 26 drives the top plate to move upward until the top plate abuts against the bottom surface of the frame 6 and / or the material fixing mechanism 7, so as to provide support force to the frame 6 and / or the material fixing mechanism 7, reduce the load that the frame 6 and / or the material fixing mechanism 7 needs to bear, and play a protective role for the frame 6 and / or the material fixing mechanism 7.

[0031] In this embodiment, the gas-liquid separation vacuum device 15 is detachably and sealed to the air extraction port via a docking mechanism. The docking mechanism includes a pipe joint 27 installed on the frame 6 or piercing the bottom plate 8 and communicating with the air extraction port, a lifting plate 28 that is raised and lowered in the lower cavity 2, a connecting pipe 29 installed on the lifting plate 28 and detachably and sealed to the pipe joint 27, and a docking drive mechanism 30 installed in the lower cavity 2. The docking drive mechanism 30 is driven to connect with the lifting plate 28, and the connecting pipe 29 is communicated with the gas-liquid separation vacuum device 15.

[0032] In practical applications, when it is necessary to evacuate the punctured air bag, the docking drive mechanism 30 drives the lifting plate 28, along with the connecting pipe 29, to move upward until the connecting pipe 29 and the pipe connector 27 are sealed together. The gas-liquid separation vacuum device 15 then evacuates the air bag and the lower cavity 2. After vacuuming, the docking drive mechanism 30 drives the lifting plate 28, along with the connecting pipe 29, to move downward until the connecting pipe 29 separates from the pipe connector 27, allowing the frame 6 to move away from the lower cavity 2. This structural design allows for detachable docking of the pipe connector 27 and the connecting pipe 29, facilitating easy assembly and disassembly. Compared to using a direct air pipe to the evacuation port and the gas-liquid separation vacuum device 15, this application reduces the amount of air pipe used and avoids problems such as tangling of the air pipe during the reciprocating movement of the frame 6.

[0033] Specifically, the gas-liquid separation vacuum device 15 includes a connecting pipe 31, a liquid storage tank 32, a valve body 33, an on / off actuator 34, and a vacuum pump. One end of the connecting pipe 31 is connected to the connecting pipe 29, and the other end of the connecting pipe 31 is connected to the air inlet of the liquid storage tank 32. The valve body 33 is installed at one end of the liquid storage tank 32, and the on / off actuator 34 is installed on the valve body 33. The valve body 33 is provided with an air inlet and an air outlet. One end of the air inlet is connected to the air outlet of the liquid storage tank 32, and the other end of the air inlet is connected to one end of the air outlet via the on / off actuator 34. The other end of the air outlet is connected to the vacuum pump. The on / off actuator 34 is used to cut off or open the air inlet and the air outlet.

[0034] In practical applications, when the vacuum pump is activated, the on / off end of the on / off actuator 34 retracts, connecting the inlet and outlet channels. The vacuum pump evacuates the punctured gas bag and lower cavity 2 via the outlet channel, inlet channel, liquid tank 32, connecting pipe 31, connecting pipe 29, pipe joint 27, evacuation port, vacuum chamber, and multiple puncture holes 20. Gas and electrolyte mixed with gas enter the liquid tank 32 through the puncture holes 20, vacuum chamber, evacuation port, pipe joint 27, and connecting pipe 29. The electrolyte falls to the bottom of the liquid tank 32 under gravity, separating the gas from the electrolyte. The gas is discharged through the inlet channel, outlet channel, and vacuum pump. When it is necessary to stop vacuuming, the on / off end of the on / off actuator 34 extends, disconnecting the inlet and outlet channels, facilitating vacuum control. Because the gas and electrolyte are separated, the electrolyte will not pollute the environment or damage the vacuum pump, and it is also easy to collect the electrolyte.

[0035] Specifically, a drain switch 35 is provided at the bottom of the storage tank 32. When it is necessary to clean the electrolyte in the storage tank 32, simply open the drain switch 35 to drain the electrolyte in the storage tank 32. The operation is simple and convenient, making it easy to clean the electrolyte.

[0036] In this embodiment, the inner wall of the lower cavity 2 is equipped with a slot plate 36, and the side wall of the frame 6 is equipped with a locking member 37. The locking member 37 engages with the slot plate 36. The locking member 37 can be a roller, ball, rotating ball, or bearing, etc. During the process of the frame 6 moving into the lower cavity 2, when the locking member 37 engages with the slot plate 36, it indicates that the frame 6 has moved into place, thereby positioning the frame 6. The slot plate 36 supports the locking member 37, reducing the load that the frame 6 needs to bear and protecting the frame 6.

[0037] In this embodiment, the bottom wall of the vacuum chamber is provided with a guide slope, the slope of which is inclined towards the evacuation port. The guide slope guides the gas and electrolyte, improving the efficiency of gas and electrolyte flow to the evacuation port, thereby improving the efficiency and quality of vacuuming and reducing the probability of electrolyte residue in the vacuum chamber.

[0038] In this embodiment, the material positioning mechanism 7 includes a suction plate 38 mounted on the frame 6, a baffle 39 mounted on the front side of the suction plate 38, a positioning plate 40 movably mounted on the rear side of the suction plate 38, and a positioning driver 41 mounted on the outside of the side cover plate 5. The positioning driver 41 is drivenly connected to the positioning plate 40. The positioning driver 41 is used to drive the positioning plate 40 to move closer to or away from the baffle 39. The top surface of the suction plate 38 is provided with a plurality of suction holes 42. The inside of the suction plate 38 is provided with a suction channel. The plurality of suction holes 42 are all connected to the suction channel. The suction channel is connected to a vacuum alarm. The vacuum alarm is mounted on the side wall of the suction plate 38. The encapsulation space 19 is located between the piercing bottom plate 8 and the baffle 39. The positioning driver 41 can be a cylinder.

[0039] In practical applications, the battery is placed flat on the suction plate 38, with the battery body positioned between the baffle 39 and the positioning plate 40. The air pocket of the battery protrudes beyond the baffle 39 and pierces the bottom plate 8 to support the air pocket. Then, the positioning driver 41 drives the positioning plate 40 to move closer to the baffle 39, pushing the rear of the battery body until the front of the battery body contacts the baffle 39. The baffle 39 and the positioning plate 40 clamp the battery body, thus positioning it. At this time, the multiple suction holes 42 on the suction plate 38 firmly hold the battery body, ensuring the battery's positional accuracy and stability on the suction plate 38. When a vacuum leak occurs, the vacuum alarm will sound, allowing maintenance personnel to perform timely maintenance; for example, if the battery shifts position, causing the multiple suction holes 42 to fail to hold the battery body firmly.

[0040] Specifically, an elastic buffer 43 is provided between the driving end of the positioning driver 41 and the positioning plate 40. Preferably, the elastic buffer 43 is a spring. When the positioning plate 40 abuts against the rear side of the battery body, the elastic buffer 43 plays a buffering and protective role, avoiding hard impact collisions between the positioning plate 40 and the battery body, reducing noise, and also preventing excessive pressure from the positioning plate 40 and the baffle 39 on the battery body, which could damage the battery body, thus protecting the battery.

[0041] Specifically, the upper cover plate 3 and the lower cavity 2 are detachably connected via a locking structure; by adding a locking structure, the upper cover plate 3 can be more securely fitted onto the lower cavity 2.

[0042] Preferably, the locking structure includes a locking seat 44 installed on the side wall of the lower cavity 2, a threaded sleeve 45 rotatably connected to the locking seat 44, a bolt 46 threadedly connected to the threaded sleeve 45, and a groove 47 recessed in the upper cover plate 3, wherein the bolt 46 can be engaged in the groove 47. When the locking structure is in the locked state, the bolt 46 is engaged in the groove 47. Tightening the bolt 46 causes it to move down along the threaded hole of the threaded sleeve 45 until the nut of the bolt 46 locks the upper cover plate 3 onto the lower cavity 2. When it is necessary to separate the upper cover plate 3 and the lower cavity 2, loosening the bolt 46 causes the nut of the bolt 46 to separate from the upper cover plate 3. The bolt 46, along with the threaded sleeve 45, rotates outward toward the groove 47 until the bolt 46 disengages from the groove 47. Driven by the opening and closing drive mechanism 14, the upper cover plate 3 can then be opened relative to the lower cavity 2.

[0043] This invention also includes a battery processing device that is easy to maintain, comprising a machine base 48 and the aforementioned flat-lying puncture, vacuuming, and encapsulation integrated machine. The flat-lying puncture, vacuuming, and encapsulation integrated machine is slidably connected to the machine base 48. The machine base 48 is rotatably connected to an opening and closing door 49, which is correspondingly configured with the flat-lying puncture, vacuuming, and encapsulation integrated machine. During processing, the opening and closing door 49 is closed, and the flat-lying puncture, vacuuming, and encapsulation integrated machine operates within the machine base 48. When maintenance is required, the opening and closing door 49 is opened, and the flat-lying puncture, vacuuming, and encapsulation integrated machine is pulled out of the machine base 48, allowing for easy maintenance of the machine outside the machine base 48. The operation is simple and convenient.

[0044] In this embodiment, there are multiple horizontal puncture, vacuuming, and packaging integrated machines and multiple opening / closing doors 49. These multiple horizontal puncture, vacuuming, and packaging integrated machines are arranged within the machine base 48, with each opening / closing door 49 corresponding to one horizontal puncture, vacuuming, and packaging integrated machine. This structural design allows multiple horizontal puncture, vacuuming, and packaging integrated machines to operate simultaneously, improving the efficiency of battery processing. When one of the horizontal puncture, vacuuming, and packaging integrated machines requires maintenance, simply open the corresponding opening / closing door 49 and pull the corresponding horizontal puncture, vacuuming, and packaging integrated machine out of the machine base 48. Maintenance is convenient, and the remaining horizontal puncture, vacuuming, and packaging integrated machines continue to operate normally without interfering with each other.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
