Description

Technical Field

[0001] The utility model relates to the field of cavity closing and sealing machines, in particular to an automatic interlocking cavity closing and sealing mechanism. Background Art

[0002] Liquid injection is a key link in the lithium battery production process, which will directly affect the performance of lithium batteries. The poor sealing of the vacuum sealing environment during liquid injection and the slow penetration of electrolyte are still the main problems in the current lithium battery production. At present, the sealing equipment for battery liquid injection automatically transports the battery to the static station through the tray after the battery liquid injection is completed. It drives the static cavity downward through the drive unit to combine with the tray of the equipment for sealing. Since the drive unit is located above the static cavity, and the connection position between the drive unit and the static cavity deviates from the center of the static cavity, this can easily cause the sealing of the static cavity and the edge of the equipment tray to be inconsistent, which can easily cause a loose seal. Summary of the Invention

[0005] By adopting the above-mentioned technical solution, the driving unit drives the upper cavity to descend and combine with the lower cavity. When the upper cavity and the lower cavity combine, the connecting plate approaches the upper cavity, and the elastic member is deformed by the push of the connecting plate, so that the elastic force of the elastic member can act on the upper cavity, thereby further strengthening the sealing performance of the combination of the upper cavity and the lower cavity, so as to ensure the good sealing performance and sealing effect of the combination of the upper cavity and the lower cavity; at the same time, the downward-moving connecting plate can push the self-locking component to contact the roller bearing to achieve self-locking fixation of the upper cavity relative to the lower cavity, and when the locking devices on both sides of the upper cavity are extended, the upper cavity can be locked; when it needs to be unlocked, the locking devices on both sides of the upper cavity reset and retract to exit the lock on the upper cavity. When the driving unit drives the connecting plate to rise and reset, the raised connecting plate drives the self-locking component to reset and release the conflict with the roller bearing.

[0006] Preferably, the self-locking assembly includes a guide seat, a self-locking guide rod movably extending through the guide seat, a drive rod connected between one end of the self-locking guide rod and the connecting plate, and an inclined surface provided on the other end of the self-locking guide rod.

[0008] By adopting the above-mentioned technical solution, when the connecting plate pushes the self-locking guide rod to extend through the driving rod, the extended self-locking guide rod can push the roller bearing to roll on its inclined surface. The inclined surface of the self-locking guide rod is pushed downward by the roller bearing to generate downward pressure on the upper cavity, making the sealing of the combination of the upper cavity and the lower cavity more stable.

[0009] Preferably, the number of the self-locking components, roller bearings and drive rods is the same.

[0010] Preferably, there are two or more driving rods.

[0011] In one embodiment, when two driving rods are provided, the two driving rods are connected to two ends of the connecting plate.

[0017] In another embodiment, when four positioning rods are provided, the four positioning rods are respectively located on four sides of the upper cavity.

[0018] Preferably, there is more than one locking device.

[0019] Preferably, there are two or more guide rod and guide sleeve assemblies. When there are two guide rod and guide sleeve assemblies, the two guide rod and guide sleeve assemblies are symmetrically arranged on both sides of the driving unit.

[0020] By adopting the above-mentioned technical solution, the guide rod and guide sleeve assembly can guide the lifting and lowering movement of the upper cavity to avoid deviation in the lifting and lowering of the upper cavity, which ensures that the upper cavity can be accurately aligned with the lower cavity and closed, and avoids deviation between the upper cavity and the lower cavity after closing, which affects the sealing of the upper cavity and the lower cavity after closing.

[0021] Preferably, two or more self-locking assemblies are provided. When two self-locking assemblies are provided, the two self-locking assemblies are provided on both sides of the connecting plate; when four self-locking assemblies are provided, the four self-locking assemblies are provided at the four corners of the upper surface of the upper cavity. The above design can ensure a consistent sealing effect between the upper cavity and the lower cavity.

[0022] Preferably, there are two or more roller bearings. When there are two roller bearings, the two roller bearings are respectively mounted on the middle portions of the two positioning rods. When there are four roller bearings, a roller bearing is respectively mounted on both ends of each positioning rod.

[0023] By adopting the above technical solution, the design of the above number of self-locking components and roller bearings makes it possible to choose to self-lock the upper cavity from any two opposite sides according to production needs, or to self-lock the upper cavity from four sides at the same time, so as to ensure a good sealing effect between the upper cavity and the lower cavity.

[0024] Preferably, the driving unit and the locking device may each be a cylinder, but this is not a limitation, and all parts or components that can perform telescopic motion or push an object to perform linear reciprocating motion may be attempted.

[0025] Preferably, the elastic member is a spring.

[0026] It should be noted that the guide rod and guide sleeve assembly includes a guide sleeve and a guide rod passing through the guide sleeve.

The controller is a PLC programmable logic controller. The PLC programmable logic controller can be a programmable logic controller produced in Shenzhen and with model number XDS-40T-D, but is not limited to this.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: by providing a self-locking component on the upper cavity and designing the structure of the self-locking component, when the upper cavity is driven by the driving unit and closes with the lower cavity, the elastic member is compressed, the self-locking guide rod extends under the roller bearing, the roller bearing rolls on the inclined surface of the self-locking guide rod, and the inclined surface of the self-locking guide rod is pushed downward by the roller bearing, so that the sealing of the upper cavity and the lower cavity is further stabilized, the combination of the upper cavity and the lower cavity is tighter, and the combination of the upper cavity and the lower cavity is sealed. The effect is better; at the same time, it also provides locking devices on both sides or four sides of the upper cavity. When the locking devices are extended, the upper cavity can be limited to complete self-locking and interlocking, which makes the sealing of the upper cavity and the lower cavity more stable. The overall structural design enables the upper cavity and the lower cavity to have the advantages of precise positioning, more stable sealing and better sealing effect, so as to avoid the center deviation of the combination of the upper cavity and the lower cavity and avoid the problems of loose sealing and inconsistent sealing effect at the edge position of the combination of the upper cavity and the lower cavity.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] Reference Figures 1 to 2As shown, an automatic interlocking cavity sealing mechanism of the present invention includes a frame 1, a flange plate 2 is provided on the frame 1, a drive unit 3 is provided on the flange plate 2, a connecting plate 4 is provided on the output end of the drive unit 3, a guide rod and guide sleeve assembly 5 is respectively installed at both ends of the flange plate 2, the lower end of the guide rod and guide sleeve assembly 5 is connected to the upper cavity 6, the upper cavity 6 is lifted and lowered on the guide rod and guide sleeve assembly 5, a lower cavity 7 is provided below the upper cavity 6 for use with the upper cavity 6, and the connection plate 4 and the upper cavity 6 are connected. An elastic member 8 is connected in between, and a guide pin 9 is provided through the connecting plate 4. The connecting plate 4 moves up and down on the guide pin 9. The lower end of the guide pin 9 is connected and installed with the upper cavity 6. A self-locking component 10 is provided on the upper cavity 6. A positioning rod 11 is provided in the middle of the frame 1. A roller bearing 12 is provided on the positioning rod 11. The self-locking component 10 and the roller bearing 12 are arranged opposite to each other. A locking device 13 for locking the upper cavity 6 is provided at the lower end of the frame 1. The locking device 13 is fixed to the frame 1 through the mounting plate 18.

[0035] In one embodiment, the self-locking assembly 10 includes a guide seat 14, a self-locking guide rod 15 is movably provided through the guide seat 14, a driving rod 16 is connected between one end of the self-locking guide rod 15 and the connecting plate 4, and a slope 17 is provided on the other end of the self-locking guide rod 15.

[0036] In one embodiment, the self-locking assembly 10 , the roller bearing 12 , and the driving rod 16 are provided in the same number.

[0037] In one embodiment, one end of the driving rod 16 is axially connected to the self-locking guide rod 15 , and the other end of the driving rod 16 is axially connected to the connecting plate 4 .

[0038] In one embodiment, more than one guide pin 9 is provided.

[0039] In one embodiment, more than one positioning rod 11 is provided.

[0040] In one embodiment, more than one locking device 13 is provided.

[0041] In one embodiment, the structural design principle of the automatic interlocking cavity sealing mechanism is as follows: a flange plate 2 is provided on a frame 1, a drive unit 3 is provided on the flange plate 2, and a guide rod and guide sleeve assembly 5 is installed at each end of the flange plate 2. The lower end of the guide rod and guide sleeve assembly 5 is connected to the upper cavity 6, so that the upper cavity 6 can move up and down along the guide rod and guide sleeve assembly 5 under the drive of the drive unit 3. The guide rod and guide sleeve assembly 5 guides the lifting and lowering movement of the upper cavity 6 to prevent the movement of the upper cavity 6 from being offset. When the drive unit 3 drives the upper cavity 6 to move downward to combine with the lower cavity 7, the upper cavity 6 is guided by the guide rod and guide sleeve assembly 5 to improve the accuracy of its combination and positioning with the lower cavity 7, thereby improving the sealing degree of the combination between the upper cavity 6 and the lower cavity 7.

[0042] An elastic part 8 is connected between the connecting plate 4 and the upper cavity 6. When the driving unit 3 drives the connecting plate 4 to approach the upper cavity 6, the elastic part 8 will be deformed by the push of the connecting plate 4. The elastic force generated by the deformed elastic part 8 can act on the upper cavity 6, thereby further enhancing the sealing performance of the combination of the upper cavity 6 and the lower cavity 7.

[0043] The invention provides one or more self-locking components 10 on the upper cavity 6, and connects one end of the self-locking guide rod 15 in the self-locking component 10 to the connecting plate 4 with a driving rod 16, and the other end of the self-locking guide rod 15 is provided with an inclined surface 17. At the same time, the positioning rod 11 in the frame 1 is provided with a roller bearing 12, and the self-locking component 10 is arranged opposite to the roller bearing 12; when the driving unit 3 drives the self-locking guide rod 15 in each self-locking component 10 to extend toward the roller bearing 12 through the connecting plate 4 and the driving rod 16 in turn, the driving unit 3 generates a driving force. The power will drive the roller bearing 12 to come into contact with the inclined surface 17 on the self-locking guide rod 15 and then roll on the inclined surface 17 of the self-locking guide rod 15. At this time, the inclined surface 17 of the self-locking guide rod 15 is pushed downward by the roller bearing 12 to drive the upper cavity 6 to move further downward and tightly combine with the lower cavity 7, thereby realizing self-locking fixation of the upper cavity 6 relative to the lower cavity 7. The structural design of the self-locking component 10 ensures that the sealing effect of the edge combination position of the upper cavity 6 and the lower cavity 7 can remain consistent, and the sealing of the joint between the upper cavity 6 and the lower cavity 7 is more stable and the sealing effect is better.

[0044] It also has a locking device 13 at the lower end of the frame 1 for locking the upper cavity 6, and there is more than one locking device 13. When each locking device 13 extends toward the upper cavity 6, it can lock and limit the upper cavity 6 to avoid center deviation in the combination of the upper cavity 6 and the lower cavity 7, which affects the sealing performance and sealing effect. When it needs to be unlocked, each locking device 13 retreats and resets in the direction away from the upper cavity 6 to exit or release the lock on the upper cavity 6. At the same time, the drive unit 3 drives the connecting plate 4 to rise and reset, and the connecting plate 4 pulls the self-locking guide rod 15 of the self-locking assembly 10 to retract and reset through the drive rod 16 to exit or release the conflict with the roller bearing 12, so that the self-locking assembly 10 releases the self-locking of the upper cavity 6.

[0045] Its overall structural design realizes that the upper cavity 6 can be precisely combined with the lower cavity 7 through the cooperation of the guide rod guide sleeve assembly 5 and the self-locking assembly 10, so as to avoid the deviation of the combination of the upper cavity 6 and the lower cavity 7. When the guide rod guide sleeve assembly 5, the self-locking assembly 10 and the locking device 13 are used in conjunction with each other, not only can the upper cavity 6 and the lower cavity 7 automatically complete the combination, self-locking and interlocking, but it also makes the upper cavity 6 and the lower cavity 7 have the advantages of precise combination positioning, more stable combination sealing and better combination sealing effect. It effectively solves the current problem of battery filling sealing equipment, in which the connection position of the driving unit and the static cavity deviates from the center of the static cavity, resulting in loose sealing, inconsistent sealing and poor overall sealing effect at the connection position of the static cavity and the edge of the equipment tray.

[0046] The above embodiment is only an example of the present invention and is not intended to limit the implementation and scope of rights of the present invention. Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
