Description

Technical Field

[0001] This utility model relates to the field of vacuum plugging machine technology, specifically to a main and auxiliary compartment separation mechanism for a vacuum plugging machine. Background Technology

[0002] Vacuum plugging machines are widely used in the field of precision vacuum machining. Their main chamber usually needs to maintain a constant vacuum environment to ensure machining accuracy, while the auxiliary chamber, as a workpiece transition area, requires frequent workpiece loading and unloading.

[0003] When the workpiece is being processed in the main compartment, the main compartment and the auxiliary compartment are connected and both need to be in a vacuum state. The top of the auxiliary compartment has a slot and the opening and closing are controlled by a sealing cover. The auxiliary compartment is equipped with a temporary storage platform driven by a lifting mechanism. After the workpiece is placed on the temporary storage platform through the slot, it is lowered by the lifting mechanism and then transferred to the main compartment for subsequent processing through the transfer mechanism in the auxiliary compartment. However, when placing workpieces to be processed onto the temporary storage platform in the auxiliary compartment, the slotted sealing cover on the upper part of the auxiliary compartment needs to be opened. However, traditional main and auxiliary compartments lack an effective separation mechanism, causing the external atmospheric pressure environment to directly connect with the auxiliary and main compartments when the sealing cover is opened. This forces the main compartment to be depressurized to atmospheric pressure before the sealing cover can be opened, and then re-vacuumed after the workpiece is placed. This results in frequent depressurization and vacuuming operations in the main compartment, making the overall operation time-consuming and labor-intensive, severely impacting production rhythm. Utility Model Content

[0004] In view of this, the present invention provides a main and auxiliary compartment separation mechanism for a vacuum plugging machine, which ensures that the main compartment remains in a vacuum state during the opening and closing of the sealing cover, eliminating the need for frequent depressurization and vacuuming operations in the main compartment, thereby making the workpiece processing process more time-saving and labor-saving, and improving the production pace.

[0005] To solve the above-mentioned technical problems, this utility model provides a main and auxiliary compartment separation mechanism for a vacuum plugging machine, including a main compartment and an auxiliary compartment that are interconnected. A slot is provided above the auxiliary compartment, and the slot's opening and closing are controlled by a sealing cover. The vacuum pump unit's extraction pipe passes through the sealing cover and extends to the space below it. A frame-shaped component is slidably fitted onto the inner wall of the slot. In the initial state, with the sealing cover detached from the slot, the lower end face of the frame-shaped component presses against the upper wall of the temporary storage platform. Due to the fit between the frame-shaped component and the temporary storage platform, a chamber isolated from the vacuum environment inside the auxiliary compartment is formed. This chamber is exposed to the outside and is under normal pressure, allowing the operator to place the workpiece on the temporary storage platform. After moving the sealing cover to close the slot, the chamber is extracted through the vacuum pump and extraction pipe. The air inside the chamber is purged until the main chamber and the auxiliary chamber reach the same vacuum level. At this point, the frame component can rise, and the lifting mechanism pushes the frame component upward, causing its lower end face to detach from the upper wall of the temporary storage platform. This connects the main chamber and the auxiliary chamber, placing them in the same vacuum environment. Finally, the workpiece on the temporary storage platform can be transferred to the main chamber for processing via a transfer mechanism. The design of the frame component allows for the formation of a controllable vacuum and atmospheric pressure chamber within the auxiliary chamber, enabling workers to place workpieces onto the temporary storage platform through the chamber. Since the main chamber remains in a vacuum state during the opening and closing of the sealing cover, frequent depressurization and vacuuming operations are unnecessary, making the workpiece processing more time-saving and labor-saving, and improving production speed.

[0006] The frame component includes a fixed frame fixed to the inner wall of the auxiliary compartment, with the inner sidewall of the fixed frame coplanar with the inner sidewall of the slot; it also includes a movable frame, which slides against the inner sidewall of the fixed frame via its outer sidewall. Initially, with the sealing cap detached from the slot, the bottom surface of the movable frame adheres to the upper wall of the temporary storage platform, forming a chamber isolated from the vacuum ring inside the auxiliary compartment. At this point, the workpiece can be placed on the upper wall of the temporary storage platform. Subsequently, the sealing cap is placed over the upper part of the slot to close it. Then, a vacuum pump is used to evacuate the air from the chamber, creating the same vacuum level as the auxiliary compartment. At this point, a lifting mechanism pushes the movable frame upwards and simultaneously pushes the temporary storage platform downwards, separating the movable frame and the temporary storage platform and connecting the chamber to the auxiliary compartment. Finally, a transfer mechanism transfers the workpiece from the temporary storage platform to the main compartment for processing.

[0007] The lifting mechanism includes four first cylinders fixedly mounted on the inner wall of the slot. The four first cylinders are grouped in pairs, with each pair fixed to two symmetrical inner sidewalls of the slot. The cylinder body of the first cylinder is fixed to the inner sidewall of the slot, and its telescopic end is fixed to the upper wall of the movable frame. The four first cylinders are synchronously controlled by an external control platform, enabling the movable frame to perform lifting operations. It also includes four second cylinders, whose cylinder bodies are fixed to the bottom surface of the auxiliary compartment, and their telescopic ends are fixed to the lower surface of the temporary storage platform. These four second cylinders are also synchronously controlled by an external control platform. When the chamber and the auxiliary compartment are at the same vacuum level... Then, the second and first cylinders are activated. The telescopic end of the first cylinder pushes the movable frame upward, and the telescopic end of the second cylinder pushes the temporary storage platform downward, thereby detaching the movable frame from the upper wall of the temporary storage platform and connecting the interior of the chamber and the auxiliary compartment. After the workpiece is processed and placed back on the temporary storage platform by the transfer mechanism, the first and second cylinders are activated again. The telescopic end of the first cylinder pushes the movable frame downward, and the second cylinder drives the temporary storage platform upward, so that the bottom surface of the movable frame abuts against the top surface of the temporary storage platform, thus isolating the chamber and the auxiliary compartment again. Then, the vacuum pump releases air into the chamber, bringing the chamber to normal atmospheric pressure. After that, the sealing cover can be opened for subsequent operations.

[0008] The lower end of the fixed frame extends inward to form an annular inner extension strip. When the first cylinder drives the movable frame to descend, the lower wall of the movable frame can first adhere to the upper wall of the inner extension strip. At this time, the first cylinder is closed, and the second cylinder pushes the temporary storage platform upward, so that the upper wall of the temporary storage platform adheres to the lower wall of the movable frame. The inner extension strip can limit the distance of the movable frame's descent, preventing the movable frame from falling too far and detaching from the fixed frame. Furthermore, the contact between the inner extension strip and the bottom surface of the movable frame further improves the sealing between the two, preventing air leakage from the chamber.

[0009] The frame component includes an isolation frame that slides against the four inner side walls of the slot. When the bottom of the isolation frame abuts against the upper wall of the temporary storage platform, its side walls remain in contact with the inner wall of the slot. The isolation frame and the temporary storage platform together form an isolation chamber. After the workpiece is placed on the temporary storage platform, the sealing cover is closed to seal the slot. Then, a vacuum pump is used to extract air from the chamber, bringing it to the same vacuum level as the auxiliary chamber. The isolation frame is then lifted by a lifting mechanism, and subsequently, a transfer mechanism transfers the workpiece to the main chamber for processing. Once processing is complete... Then, the workpiece is transferred to the temporary storage platform. The lifting mechanism lowers and resets the isolation frame, which then adheres to the upper wall of the temporary storage platform, thus re-isolating the chamber from the auxiliary chamber. Subsequently, a vacuum pump releases air into the chamber, bringing it to normal atmospheric pressure. At this point, the sealing cover can be opened, and the workpiece can be removed from the temporary storage platform in the chamber. After removal, the next workpiece to be processed can be placed for subsequent identical operations. Thus, during the process of removing and placing workpieces, the main chamber remains under vacuum, eliminating the need for frequent evacuation and venting of the main chamber, thereby saving operation time.

[0010] The upper end of the isolation frame is provided with a radially extending extension strip, and the outer diameter of the extension strip is larger than the inner diameter of the slot. When the isolation frame rises, the extension strip rises with the isolation frame and detaches from the edge of the slot. When the bottom of the isolation frame abuts against the upper wall of the temporary storage platform, the extension strip can overlap the edge of the slot to form a gravity limit. This not only prevents the isolation frame from detaching from the slot due to excessive downward movement, but also further improves the sealing between the isolation frame and the slot, preventing air leakage from the chamber.

[0011] The lifting mechanism includes four third cylinders fixed on the outer extension bar. The four third cylinders are grouped in pairs, with each pair of third cylinders fixed on opposite sides of the upper part of the outer extension bar. The cylinder body of the third cylinder is fixed on the outer extension bar. By opening through holes in the outer extension bar, the telescopic end of the third cylinder passes through the through holes of the outer extension bar and is fixed to the upper wall of the auxiliary compartment. When the third cylinder is activated, the telescopic end extends outward, thereby pushing the cylinder body and the outer extension bar to rise. This causes the outer extension bar to drive the isolation frame to rise, thereby connecting the interior of the chamber and the auxiliary compartment.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The main chamber maintains a continuous vacuum environment. The frame components and temporary storage platform form switchable independent chambers. During the loading and unloading of workpieces, the main chamber does not need to be depressurized and always maintains a vacuum state, which completely solves the efficiency loss problem caused by frequent depressurization and vacuuming in the existing technology.

[0013] 2. Processing efficiency is significantly improved. The cycle of depressurization and vacuuming in the main chamber is eliminated. The local switching between atmospheric pressure and vacuum states is achieved directly through the chamber, which greatly shortens the workpiece transfer time and makes the production line cycle more compact.

[0014] 3. Reliable sealing: The precise sliding fit between the frame component and the inner wall of the groove, combined with the limiting and sealing design of the inner and outer extension strips, forms a multi-layer sealing structure, effectively preventing air leakage from the cavity.

[0015] 4. Cost optimization: By reducing the use of cylinders, production costs can be reduced during equipment manufacturing, and operational stability can be improved. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-8 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] Example 1: A 100-cell partition mechanism for the main and auxiliary compartments of a vacuum plugging machine, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: The system includes a main compartment 102, with a secondary compartment 100 fixed to one outer wall of the main compartment 102. The secondary compartment 100 and the main compartment 102 are interconnected via a connecting part. A slot 101 is provided above the secondary compartment 100, and a sealing cover 200 is provided on the slot 101. The sealing cover 200 can cover the slot 101 to achieve a sealed closure, or it can be removed from the slot 101 to expose the slot 101. The vacuum pump unit's extraction pipe passes through the sealing cover 200 and extends to the space below it. A frame-shaped component is slidably fitted onto the inner wall of the slot 101. according to Figure 3As shown, in the initial state, with the sealing cover 200 detached from the slot 101, the lower end face of the frame component presses against the upper wall of the temporary storage platform 400, and the outer wall of the frame component is always in close contact with the inner wall of the slot 101. Because the frame component and the temporary storage platform 400 are in close contact, a chamber isolated from the vacuum environment inside the auxiliary compartment 100 is formed. This chamber is exposed to the outside and is under normal pressure, allowing the operator to place the workpiece on the temporary storage platform 400. according to Figure 4 As shown, after the movable sealing cover 200 closes the slot 101, the operator uses a vacuum pump to extract air from the chamber through its extraction pipe until the chamber and the auxiliary chamber 100 reach the same vacuum level. At this time, the frame component can be raised. The lifting mechanism pushes the frame component to rise, so that the lower end face of the frame component is separated from the upper wall of the temporary storage table 400, thereby connecting the chamber and the auxiliary chamber 100 and placing them in the same vacuum environment. Finally, the workpiece on the temporary storage table 400 can be transferred to the main chamber 102 for processing through the transfer mechanism. By designing the frame-shaped components, a chamber with controllable vacuum and atmospheric pressure can be formed inside the auxiliary chamber 100, allowing workers to place workpieces onto the temporary storage table 400 through the chamber. Since the main chamber 102 is always in a vacuum state during the opening and closing of the sealing cover 200, there is no need for frequent depressurization and vacuuming operations on the main chamber 102, making the workpiece processing process more time-saving and labor-saving, and improving the production rhythm. Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the frame component includes a fixed frame 500 fixed to the inner wall of the sub-compartment 100, and the fixed frame 500 is located at the lower end edge of the slot 101, so that the inner side wall of the fixed frame 500 is coplanar with the inner side wall of the slot 101. It also includes a movable frame 300, and both the movable frame 300 and the fixed frame 500 are rectangular structures. The movable frame 300 is slidably fitted to the inner side wall of the fixed frame 500 through its outer side wall. In the initial state, with the sealing cover 200 disengaged from the slot 101, the bottom surface of the movable frame 300 is attached to the upper wall of the temporary storage platform 400 to form a chamber isolated from the vacuum ring in the auxiliary compartment 100. At this time, the workpiece can be placed on the upper wall of the temporary storage platform 400.

[0020] Then, the sealing cap 200 is placed over the upper part of the slot 101 to close the slot 101. The air in the chamber is then extracted by a vacuum pump to form the same vacuum level as that in the auxiliary chamber 100. At this point, the movable frame 300 is pushed up by the lifting mechanism, and the temporary storage platform 400 is pushed down at the same time to separate the movable frame 300 and the temporary storage platform 400, thereby connecting the interior of the chamber and the auxiliary chamber 100. Finally, the workpiece on the temporary storage platform 400 is transferred to the main chamber 102 for processing by the transfer mechanism.

[0021] Specifically, according to Figure 3 and Figure 4 As shown, the lifting mechanism includes four first cylinders 301 fixedly installed on the inner wall of the slot 101. The four first cylinders 301 are grouped in pairs, and each pair of first cylinders 301 is fixed on two symmetrical inner side walls of the slot 101. The cylinder body of the first cylinder 301 is fixed on the inner side wall of the slot 101, and its telescopic end is fixed on the upper wall of the movable frame 300. The four first cylinders 301 are synchronously controlled by an external control platform, so that the movable frame 300 can be lifted and lowered by the four first cylinders 301. It also includes four second cylinders 401, which are distributed at the four corners of the bottom of the temporary storage platform 400. The cylinders 401 are fixed to the bottom surface of the auxiliary compartment 100 within their cylinder bodies, and their telescopic ends are fixed to the lower surface of the temporary storage platform 400. The four second cylinders 401 are synchronously controlled by an external control platform. When the sealing cover 200 closes the slot 101 and evacuates the air from the chamber, until the chamber and auxiliary compartment 100 reach the same vacuum level, the second cylinders 401 and the first cylinder 301 are activated. The telescopic end of the first cylinder 301 pushes the movable frame 300 upward, and the telescopic end of the second cylinders 401 pushes the temporary storage platform 400 downward. The movable frame 300 is lowered, thus detaching from the upper wall of the temporary storage platform 400, connecting the interior of the chamber and the auxiliary compartment 100. After the workpiece is processed and placed back on the temporary storage platform 400 via the transfer mechanism, the first cylinder 301 and the second cylinder 401 are activated again. The telescopic end of the first cylinder 301 pushes the movable frame 300 down, and the second cylinder 401 drives the temporary storage platform 400 up, so that the bottom surface of the movable frame 300 abuts against the top surface of the temporary storage platform 400, thus isolating the chamber and the auxiliary compartment 100 again. Then, the vacuum pump releases air into the chamber, bringing the chamber to normal atmospheric pressure. After that, the sealing cover 200 can be opened for subsequent operations.

[0022] Furthermore, according to Figure 3 and Figure 4 As shown, the lower end of the fixed frame 500 extends inward to form an annular inner extension strip 501, and the inner diameter of the inner extension strip 501 is smaller than the outer diameter of the movable frame 300. The outer diameter of the temporary storage platform 400 is smaller than the inner diameter of the inner extension strip 501 and larger than the inner diameter of the movable frame 300. When the first cylinder 301 drives the movable frame 300 to descend, the lower wall of the movable frame 300 can first adhere to the upper wall of the inner extension strip 501. At this time, the first cylinder 301 is closed, and the second cylinder 401 pushes the temporary storage platform 400 to rise, so that the upper wall of the temporary storage platform 400 adheres to the lower wall of the movable frame 300, and the upper surface of the temporary storage platform 400 is also at the same horizontal line position as the upper surface of the inner extension strip 501. The inner extension strip 501 can limit the falling distance of the movable frame 300, preventing the movable frame 300 from falling too far and detaching from the fixed frame 500. Furthermore, the contact between the inner extension strip 501 and the bottom surface of the movable frame 300 further improves the sealing between the two, preventing air leakage from the chamber.

[0023] It is worth mentioning that the upper surface of the inner extension strip 501 is provided with a rubber pad. The contact between the rubber pad and the lower wall of the movable frame 300 further improves the sealing between the two and prevents air from flowing out from the gap where the inner extension strip 501 and the movable frame 300 are in contact.

[0024] Example 2: like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the difference from Embodiment 1 is that the lifting and lowering of the isolation frame is controlled by the cylinder in the auxiliary compartment 100, instead of controlling the lifting and lowering of the temporary storage platform 400. Furthermore, the isolation frame directly slides into the slot 101, which is more stable than the fixed frame 500 and movable frame 300 in Embodiment 1. It also reduces the number of cylinders. Compared with the four first cylinders 301 and four second cylinders 401 in Embodiment 1, the isolation connection can be controlled by four third cylinders in this embodiment, reducing production costs.

[0025] Preferred, according to Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the frame-shaped component includes an isolation frame that slides with the four inner sidewalls of the slot 101. The four outer sidewalls of the isolation frame are respectively attached to the four inner sidewalls of the slot 101 and can slide vertically up and down along the slot 101. A support column 402 is fixedly provided at the bottom of the temporary storage platform 400, and the support column 402 is fixedly provided on the bottom surface of the auxiliary compartment 100. When the bottom of the isolation frame abuts against the upper wall of the temporary storage platform 400, its sidewalls can always contact the inner wall of the slot 101. The isolation frame and the temporary storage platform 400 are spliced ​​together to form a chamber isolated from the auxiliary compartment 100. After the workpiece is placed on the temporary storage platform 400, the sealing cover 200 is closed to close the slot 101. Then, the air in the chamber is extracted by a vacuum pump to make the chamber a vacuum state with the same vacuum degree as the auxiliary compartment 100. Then, the lifting mechanism can be used to... The isolation frame is moved upward, causing its bottom to detach from the upper wall of the temporary storage platform 400, thus connecting the chamber and the auxiliary chamber 100. The workpiece is then transferred to the main chamber 102 for processing via a transfer mechanism. After processing, it is transferred back to the temporary storage platform 400. The isolation frame is then lowered and reset via a lifting mechanism, fitting against the upper wall of the temporary storage platform 400, thus re-isolating the chamber from the auxiliary chamber 100. Subsequently, a vacuum pump is used to release air into the chamber, bringing it to normal atmospheric pressure. At this point, the sealing cover 200 can be opened, and the workpiece can be removed from the temporary storage platform 400 in the chamber. After removal, the next workpiece to be processed can be placed for subsequent identical operations. Thus, during the process of removing and placing workpieces, the main chamber 102 remains under vacuum, eliminating the need for frequent evacuation and venting of the main chamber 102, thereby saving operation time.

[0026] Specifically, according to Figure 7 and Figure 8 As shown, the upper end of the isolation frame is provided with radially extending extension strips. Since the isolation frame is a rectangular structure with four sides, the number of extension strips is also four, corresponding to the four sides of the upper end face of the isolation frame, and the outer diameter of the extension strips is larger than the inner diameter of the slot 101. When the isolation frame rises, the outer extension strip rises with the isolation frame and disengages from the edge of the slot 101; When the bottom of the isolation frame abuts against the upper wall of the temporary storage platform 400, the outer extension strip can overlap the edge of the slot 101 to form a gravity limit, which can not only prevent the isolation frame from falling off the slot 101 due to excessive downward movement, but also further improve the sealing between the isolation frame and the slot 101 and prevent air leakage from the chamber.

[0027] It is worth mentioning that the bottom of the isolation frame is equipped with a rubber pad. When the bottom of the isolation frame abuts against the top of the temporary storage platform 400, the rubber pad can improve the sealing between the two and prevent air leakage.

[0028] Furthermore, according to Figure 7 and Figure 8As shown, the lifting mechanism includes four third cylinders fixed on the outer extension bar. The four third cylinders are grouped in pairs, with each pair of third cylinders fixed on opposite sides of the upper part of the outer extension bar. The cylinder body of the third cylinder is fixed on the outer extension bar. By opening through holes in the outer extension bar, the telescopic end of the third cylinder passes through the through holes of the outer extension bar and is fixed to the upper wall of the auxiliary compartment 100. When the third cylinder is started, the telescopic end extends outward, thereby pushing the cylinder body and the outer extension bar to rise, causing the outer extension bar to drive the isolation frame to rise, thereby connecting the interior of the chamber and the auxiliary compartment 100.

[0029] It is worth mentioning that the sealing cover 200 is controlled by a linear slide to move linearly, and a device such as a cylinder is provided in the linear slide to drive the sealing cover 200 to rise and fall. The sealing cover 200 is moved above the slot 101 by the linear slide, and then the lifting device presses the sealing cover 200 to cover the slot 101 and keep it sealed. How to use this utility model: First, it needs to be clarified that this utility model relates to a vacuum plugging machine, mainly used for partitioning the main chamber 102 within the equipment. It should be noted that the vacuum pump unit and transfer mechanism are existing technologies, specifically adopting the structure in the invention patent with authorization announcement number CN119284512B. Since this utility model mainly solves the partitioning problem of the main chamber 102, the mechanisms inside the auxiliary chamber 100 and the main chamber 102 are all existing technologies and are not the innovations of this utility model. Therefore, no model is specified here, nor are the structure, working principle, and operation process described in detail. Only the usage method and installation position of the frame component are explained in detail. Initially, the sealing cover 200 does not close the slot 101. At this time, the outer extension of the isolation frame will overlap the outer edge of the slot 101, and the bottom of the isolation frame will be in close contact with the upper wall of the temporary storage platform 400. The isolation frame and the temporary storage platform 400 will form a chamber isolating the workpiece from the auxiliary compartment 100 and the main compartment 102. The operator can place the workpiece on the temporary storage platform 400, and then cover the slot 101 with the sealing cover 200 to close the slot 101, sealing the chamber. The operator starts the external vacuum pump unit and extracts the air from the chamber through the suction pipe installed on the sealing cover 200 until the chamber and the auxiliary chamber 100 reach the same vacuum level. Since the auxiliary chamber 100 and the main chamber 102 are internally connected, the chamber, auxiliary chamber 100, and main chamber 102 are all at the same vacuum level. At this point, the third cylinder can be activated, causing the telescopic end of the third cylinder to extend outward, thereby pushing the cylinder body and the outer extension bar upward. This causes the outer extension bar to drive the isolation frame upward, which in turn causes the lower end face of the isolation frame to... After detaching from the upper wall of the temporary storage platform 400, the main chamber and auxiliary compartment 100 are in a connected vacuum state. The workpiece can then be transferred from the temporary storage platform 400 to the main compartment 102 for further processing via a transfer mechanism. After processing, the workpiece is transferred back to the temporary storage platform 400 via the transfer mechanism. Then, the cylinder is activated, causing the telescopic end of the cylinder to retract, thereby driving the extension strip and the isolation frame to descend, so that the bottom of the isolation frame is in close contact with the upper wall of the temporary storage platform 400. At this time, the main chamber and auxiliary compartment 100 are isolated again. The operator then releases air into the chamber using a vacuum pump, so that the chamber returns to normal atmospheric pressure. At this time, the sealing cover 200 can be opened normally. Finally, the processed workpiece can be removed from the temporary storage platform 400. Through the design of the isolation frame, the main compartment 102 is always in a vacuum state during the opening and closing of the sealing frame. Only the chamber needs to be evacuated and vented, thus eliminating the need for frequent depressurization and vacuuming operations in the main compartment 102, making the workpiece processing more time-saving and labor-saving, and improving the production rhythm.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.

When the sealing cover (200) closes the slot (101) and draws out the air in the chamber, forming the same vacuum level as the sub-compartment (100), the lifting mechanism in the sub-compartment (100) can push the movable frame (300) upward and simultaneously push the temporary storage platform (400) downward, so that the movable frame (300) and the temporary storage platform (400) can be separated from each other, realizing the internal communication between the chamber and the sub-compartment (100).

3. The main and auxiliary compartment (100) partition mechanism of a vacuum plugging machine as described in claim 2, characterized in that: The lifting mechanism includes a plurality of first cylinders (301) fixedly installed on the inner wall of the slot (101). The telescopic end of the first cylinder (301) is fixed to the upper wall of the movable frame (300). The first cylinder (301) can drive the movable frame (300) to perform lifting operations. It also includes a second cylinder (401), and multiple second cylinders (401) are fixed at the bottom of the sub-compartment (100). The telescopic end of the second cylinder (401) is fixed to the lower surface of the temporary storage platform (400). The temporary storage platform (400) can be raised and lowered by the second cylinder (401).

4. The main and auxiliary compartment (100) partition mechanism of a vacuum plugging machine as described in claim 2, characterized in that: The lower end of the fixed frame (500) extends inward to form an annular inner extension strip (501); When the movable frame (300) descends, its bottom simultaneously presses against the upper wall of the inner extension strip (501) and the temporary storage platform (400).

5. The main and auxiliary compartment (100) partition mechanism of a vacuum plugging machine as described in claim 1, characterized in that: The frame component is an isolation frame that slides with the inner wall of the slot (101). When the bottom of the isolation frame abuts against the upper wall of the temporary storage platform (400), it forms a chamber isolated from the sub-compartment (100). When air is drawn out of the chamber and brought to the same vacuum level as the auxiliary compartment (100), the lifting mechanism can drive the isolation frame to rise and detach from the temporary storage platform (400).

6. The main and auxiliary compartment (100) partition mechanism of a vacuum plugging machine as described in claim 5, characterized in that: The upper end of the isolation frame is provided with a radially extending extension strip; When the bottom of the isolation frame abuts against the upper wall of the temporary storage platform (400), the extension strip can overlap the edge of the slot (101) to form a gravity limit; As the isolation frame rises, the extension strip rises with the isolation frame and disengages from the edge of the slot (101).

7. The main and auxiliary compartment (100) partition mechanism of a vacuum plugging machine as described in claim 5 or 6, characterized in that: The lifting mechanism includes multiple third cylinders fixed on the extension strip. The cylinder bodies of the multiple third cylinders are respectively fixed on the extension strip, and their telescopic ends pass through the extension strip and are fixed to the upper wall of the auxiliary compartment (100).
