Description

Technical Field

[0001] This utility model relates to the field of sealing mechanisms, and in particular to a glove box transition compartment sealing mechanism. Background Technology

[0002] The transition chamber isolates the internal gases of the glove box from the external gases. By sealing the transition chamber and evacuating it, gas is prevented from entering the glove box, thus achieving gas isolation. Currently, the glove box doors of lithium battery manufacturers have poor sealing performance, especially the seal between the bottom of the door and the bottom of the glove box. When transferring battery components (i.e., battery accessories) into the glove box, the incomplete seal between the bottom of the door and the bottom of the glove box allows air to easily enter, reducing the glove box's airtightness. Therefore, the industry urgently needs to develop a mechanism that can improve the overall airtightness of the glove box and ensure its good sealing performance. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a glove box transition compartment sealing mechanism.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the glove box transition chamber sealing mechanism includes a glove box, a transition chamber and a door sealing mechanism. The glove box is connected and installed to the transition chamber through the door sealing mechanism. A door clearance groove is provided at the bottom of the side of the glove box adjacent to the transition chamber. A lifting component is installed below the door clearance groove.

[0005] The hatch sealing mechanism includes a hatch, a lifting plate, a first hatch lifting and moving assembly, a second hatch lifting and moving assembly, at least two linear guide rods, and at least one hatch clamping drive device. The hatch is mounted on the first and second hatch lifting and moving assemblies via the lifting plate. The first and second hatch lifting and moving assemblies are respectively vertically and parallel to each other mounted on the inner wall of the glove box near the transition compartment. The lifting plate is movably mounted on the first and second hatch lifting and moving assemblies. At least two linear guide rods... The guide rods are horizontally mounted on the lifting plate. The hatch is movably mounted on the lifting plate via at least two linear guide rods. At least one hatch pressing drive device is horizontally mounted on the side of the lifting plate facing away from the transition compartment. The output end of the hatch pressing drive device passes through the lifting plate and is connected to the hatch. The hatch moves up and down on the inner wall of the glove box via the first hatch lifting and moving assembly and the second hatch lifting and moving assembly. The hatch pressing drive device drives the hatch to move laterally closer to or away from the lifting plate via the linear guide rods. A sealing strip is embedded on the edge of the hatch facing the transition compartment.

[0006] By adopting the above technical solution, in order to ensure that the bottom surface of the transition chamber is flush with the bottom surface of the glove box, and at the same time ensure the airtightness of the transition chamber, the glove box is connected to the transition chamber through a door sealing mechanism, and a door clearance groove is provided on the bottom of the side of the glove box adjacent to the transition chamber. The door clearance groove design expands the range of motion of the door, thereby sealing the entire transition chamber. The sealing strips arranged around the door of the transition chamber can improve the overall airtightness of the cavity inside the transition chamber and ensure its overall airtightness and sealing effect. This ensures that the glove box can achieve the required working conditions. It effectively solves the problem of poor airtightness and sealing effect of glove boxes on the market due to the unsatisfactory sealing effect between the bottom of the door and the bottom surface of the glove box.

[0007] Preferably, the first door lifting and moving assembly includes a linear guide rail, a door lifting drive device, a connecting plate, an upper limit plate, a lower limit plate, a lifting drive device mounting plate, a proximity switch mounting plate, and a proximity switch. The lifting plate is mounted on the linear guide rail. The output end of the door lifting drive device is connected to the lifting plate through the connecting plate. The upper limit plate and the lower limit plate are respectively mounted on the upper and lower sides of the connecting plate and mounted on the lifting plate. The door lifting drive device is mounted on the inner wall of the glove box through the lifting drive device mounting plate. The proximity switch is fixed inside the glove box through the proximity switch mounting plate.

[0008] Specifically, the structure and working principle of the second hatch lifting and moving assembly are the same as those of the first hatch lifting and moving assembly. The hatch lifting drive device drives the lifting plate to move up and down on the linear guide rails of the first and second hatch lifting and moving assemblies. Preferably, the lifting assembly is installed below the hatch clearance groove.

[0009] Preferably, the lifting assembly includes a top plate, a bottom plate, and at least two buffer guide rods. The at least two buffer guide rods are respectively longitudinally installed at both ends of the bottom plate, and the top plate is slidably mounted on the bottom plate via the at least two buffer guide rods.

[0010] Preferably, a door stop is provided on one side of the lower end of the linear guide rail, and the door stop is installed on the inner wall of the glove box through a stop mounting plate.

[0011] Preferably, a controller or control system is provided for signal control of components such as the first door lifting and moving assembly, the second door lifting and moving assembly, and the proximity switch. The controller is a PLC programmable logic controller, and the PLC programmable logic controller can be a programmable logic controller of model XDS-40T-D, but is not limited thereto.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0013] 1. The glove box is connected to the transition compartment via a door sealing mechanism. The door can move up and down on the inner wall of the glove box via the first and second door lifting and moving components. Under the drive of the door pressing drive device, the door can press against the hatch of the transition compartment to achieve automatic closing and opening of the transition compartment. This not only ensures good sealing after the transition compartment is closed, but also has the advantages of high efficiency and good effect in closing and opening the door.

[0014] 2. By providing a door clearance groove at the bottom of the side adjacent to the glove box and the transition chamber, it ensures that the bottom surface of the transition chamber is flush with the bottom surface of the glove box, while also ensuring the airtightness of the transition chamber. The door clearance groove design expands the range of motion of the door, making the transition chamber sealed all around. The sealing strips arranged around the door of the transition chamber can improve the overall airtightness of the internal cavity of the transition chamber and ensure good overall airtightness and sealing effect, thereby ensuring that the glove box can achieve the required working conditions. This solves the problem of poor airtightness and sealing effect of existing glove boxes on the market due to the unsatisfactory sealing effect between the bottom of the door and the bottom surface of the glove box.

[0015] 3. By providing a lifting component stop above one end of the door clearance groove to limit the lifting component, it ensures that the bottom surface of the glove box, the upper surface of the lifting component, and the bottom surface of the transition compartment are flush, thus preventing the top of the lifting component from protruding from the bottom surface of the glove box and obstructing the battery components from entering the glove box from the transition compartment.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] Reference Figures 1 to 3 As shown, this utility model discloses a glove box transition compartment sealing mechanism, comprising a glove box 1, a transition compartment 2, and a door sealing mechanism 3. The glove box 1 is connected and installed to the transition compartment 2 via the door sealing mechanism 3. A door clearance groove 4 is provided at the bottom of the side of the glove box 1 adjacent to the transition compartment 2, and a lifting assembly 12 is installed below the door clearance groove 4. The door sealing mechanism 3 includes a door 5, a lifting plate 6, a first door lifting and moving assembly 7, a second door lifting and moving assembly 8, at least two linear guide rods 9, and at least one door pressing drive device 10. The door 5 is installed on the first door lifting and moving assembly 7 and the second door lifting and moving assembly 8 via the lifting plate 6. The first door lifting and moving assembly 7 and the second door lifting and moving assembly 8 are respectively installed vertically and parallel to each other on the glove box 1 near the transition compartment. On the inner wall of one side of compartment 2, a lifting plate 6 is movably mounted on the first door lifting assembly 7 and the second door lifting assembly 8. At least two linear guide rods 9 are horizontally mounted on the lifting plate 6. The door 5 is movably mounted on the lifting plate 6 via the at least two linear guide rods 9. At least one door pressing drive device 10 is horizontally mounted on the side of the lifting plate 6 facing away from the transition compartment 2. The output end of the door pressing drive device 10 passes through the lifting plate 6 and is connected to the door 5. The door 5 moves up and down on the inner wall of the glove box 1 via the first door lifting assembly 7 and the second door lifting assembly 8. The door pressing drive device 10 drives the door 5 to move laterally closer to or away from the lifting plate 6 via the linear guide rods 9. A sealing strip 11 is embedded on the edge of the door 5 facing the transition compartment 2. The transition compartment 2 is externally connected to a vacuum system capable of evacuating it.

[0024] By adopting the above technical solution, the first hatch lifting and moving assembly 7 and the second hatch lifting and moving assembly 8 jointly drive the hatch 5 to descend until it is flush with the inner bottom surface of the glove box 1 and the inner bottom surface of the transition compartment 2, so that the hatch 5 fits and seals with the hatch opening of the transition compartment 2; when the hatch pressing drive device 10 drives the hatch 5 to approach the transition compartment 2, it presses the hatch 5 against the hatch opening of the transition compartment 2, making the transition compartment 2 more airtight and with a better sealing effect; when the hatch pressing drive device 10 drives the hatch 5 away from the transition compartment 2, it resets. Furthermore, when the hatch 5 closes, the sealing strip 11 further seals the transition compartment 2, ensuring that the airtightness of the transition compartment 2 reaches its optimal state. After the battery components are placed into the transition chamber 2, the door of the transition chamber 2 that is open to the outside is closed (that is, the door through which the battery components are placed into the transition chamber). The vacuum system evacuates the transition chamber 2. After the transition chamber 2 is evacuated, the door 5 is opened and the battery components are pulled into the glove box 1 for battery assembly production. At the same time, the door 5 is closed so that the glove box 1 can be kept in a vacuum state, which ensures that the glove box 1 has a good sealing effect and good airtightness.

[0025] In this embodiment, the door clamping drive device 10 is configured as a cylinder.

[0026] Reference Figure 2 As shown, the first door lifting and moving assembly 7 includes a linear guide rail 71, a door lifting drive device 72, a connecting plate 73, an upper limit plate 74, a lower limit plate 75, a lifting drive device mounting plate 76, a proximity switch 77, and a proximity switch mounting plate 78. The lifting plate 6 is mounted on the linear guide rail 71. The output end of the door lifting drive device 72 is connected to the lifting plate 6 through the connecting plate 73. The upper limit plate 74 and the lower limit plate 75 are respectively mounted on the upper and lower sides of the connecting plate 73 and mounted on the lifting plate 6. The door lifting drive device 72 is mounted on the inner wall of the glove box 1 through the lifting drive device mounting plate 76, and there is more than one lifting drive device mounting plate 76. The proximity switch 77 is fixed inside the glove box 1 through the proximity switch mounting plate 78.

[0027] By adopting the above technical solution, the proximity switch 77 is used to sense the lifting plate 6 descending to a predetermined position to determine whether the hatch 5 has reached the predetermined position, and the lifting stroke of the hatch 5 is limited by the stroke of the hatch lifting drive device 72, which ensures that the hatch 5 can be adapted to close with the transition chamber 2, so that the sealing of the transition chamber 2 after vacuuming is guaranteed.

[0028] In this embodiment, the door lifting drive device 72 is configured as a rodless cylinder.

[0029] Specifically, the structure and working principle of the second door lifting and moving assembly 8 are the same as those of the first door lifting and moving assembly 7. The door lifting drive device 72 drives the lifting plate 6 to move up and down on the linear guide rails 71 of the first door lifting and moving assembly 7 and the second door lifting and moving assembly 8.

[0030] Reference Figure 1 and Figure 4 As shown, the lifting assembly 12 includes a top plate 121, a bottom plate 122 and at least two buffer guide rods 123. The at least two buffer guide rods 123 are respectively longitudinally installed at both ends of the bottom plate 122. The top plate 121 is slidably mounted on the bottom plate 122 via the at least two buffer guide rods 123.

[0031] By adopting the above technical solution, when the hatch 5 is lowered to the upper surface of the top plate 121, the hatch 5 will press against the top plate 121. The buffer guide rod 123 buffers the lowering of the hatch 5. The travel of the hatch 5 is limited by the travel of the hatch lifting drive device 72, which ensures that the hatch 5 can be adapted to and closed with the transition compartment 2, thereby ensuring good sealing of the transition compartment 2 after the hatch 5 is closed and a vacuum is drawn.

[0032] Reference Figure 1 As shown, a lifting component block 13 is provided above one end of the door clearance groove 4 to limit the lifting component 12, and the lifting component block 13 is installed on the bottom surface inside the glove box 1.

[0033] By adopting the above technical solution, the lifting component stop 13 limits the lifting component 12 to ensure that the bottom surface of the glove box 1, the upper surface of the lifting component 12 and the bottom surface of the transition chamber 2 are flush. This prevents the top of the lifting component 12 from protruding from the bottom surface of the glove box 1, thus preventing battery components or battery accessories from entering the glove box 1 from the transition chamber 2.

[0034] Reference Figure 1 As shown, a door stop 14 is provided on one side of the lower end of the linear guide rail 71. The door stop 14 is installed on the inner wall of the glove box 1 through a stop mounting plate 15.

[0035] By adopting the above technical solution, the hatch stop 14 blocks and limits the descent of the hatch 5 to prevent the descending hatch 5 from colliding with the bottom of the glove box 1.

[0036] Its overall structural design enables automatic closing and opening of the transition chamber 2, and has the advantage of high efficiency in closing and opening. In order to ensure that the inner bottom surface of the transition chamber 2 is flush with the inner bottom surface of the glove box 1, and at the same time ensure the airtightness of the transition chamber 2, the glove box 1 is connected and installed to the transition chamber 2 through the door sealing mechanism 3. The door avoidance groove 4 is provided on the bottom of the side of the glove box 1 adjacent to the transition chamber 2. The design of the door avoidance groove 4 expands the range of motion of the door 5, thereby sealing the entire transition chamber 2. The sealing strips 11 arranged around the door 5 can improve the overall airtightness of the inner cavity of the transition chamber 2 and ensure its overall airtightness and sealing effect. This ensures that the glove box 1 can achieve the required working conditions. It effectively solves the problem of poor airtightness and sealing effect of the glove box 1 in the current market due to the unsatisfactory sealing effect between the bottom of the door 5 and the bottom surface of the glove box 1.

[0037] The above embodiments are merely examples of this utility model and are not intended to limit the implementation and scope of this utility model. All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
