[0051] Embodiment 1:

[0052] Reference Figure 1-7A capsule battery jig comprises an upper capsule assembly and a lower capsule assembly, wherein the upper capsule assembly comprises a jig upper cover 11 and a jig cover 13 fixed at the upper end of the jig upper cover 11, the lower capsule assembly comprises a jig lower cover 12 and a jig bottom cover 14 fixed at the bottom of the jig lower cover 12, the jig upper cover 11 comprises an upper cover inner cavity 111, a liquid injection cup assembly 2 is arranged in the upper cover inner cavity 111, the jig lower cover 12 comprises a lower cover inner cavity 121, the lower cover inner cavity 121 is used to load a battery workpiece 9, a jig locking assembly is arranged between the jig upper cover 11 and the jig lower cover 12, and the jig locking assembly can detachably connect the jig upper cover 11 and the jig lower cover 12.

[0053] It should be noted that the capsule-type battery jig described in this patent application refers to a jig that is similar to a capsule in appearance and structure and consists of two detachably connected parts. Like a capsule, the two parts are connected to form a whole, and the two parts can be disassembled to form two independent parts. When assembled into a whole, the inside of the jig can also accommodate batteries like a capsule. The "capsule-type" battery jig essentially refers to a jig for transporting batteries that has a cavity for accommodating batteries and is composed of two detachably connected parts, which is different from a traditional open battery jig.

[0054] When in use, after unlocking the fixture locking assembly, separate the upper capsule assembly from the lower capsule assembly, put the battery workpiece 9 that needs to be injected into the fixture, and after the battery workpiece 9 is put into place in the battery fixture, assemble the upper capsule assembly and the lower capsule assembly, and use the fixture locking assembly to lock the fixture upper cover 11 and the fixture lower cover 12. In the fixture locked state, the battery workpiece 9 is injected with liquid through the injection cup assembly 2 in cooperation with the external battery liquid delivery device.

[0055] In this embodiment, the jig upper cover 11 is provided with a rod step mounting hole 112 which passes through the upper and lower parts, and the jig lower cover 12 is provided with an umbrella-shaped claw insertion hole 122 which passes through the upper and lower parts. The jig locking assembly includes a locking rod 31 which is installed in the rod step mounting hole 112 and can move axially, and an umbrella-shaped claw 32 which is movably sleeved on the lower end of the locking rod 31 and can be inserted into the umbrella-shaped claw insertion hole 122. The lower end of the locking rod 31 has a locking head 311. The locking head 311 can extend into the umbrella-shaped claw 32 and force the claw of the umbrella-shaped claw 32 to expand so that the locking rod 31 and the umbrella-shaped claw 32 are locked with each other, so that the upper cover 11 of the fixture and the lower cover 12 of the fixture are locked with each other; a rod compression spring 33 is arranged in the rod step mounting hole 112, one end of the rod compression spring 33 presses on the step position in the rod step mounting hole 112, and the other end of the rod compression spring 33 acts directly or indirectly on the locking rod. At the upper end of the pull rod 31, the pull rod compression spring 33 is used to elastically force the locking head 311 of the locking pull rod 31 to enter the claw space of the umbrella-shaped claw 32 so that the umbrella-shaped claw is locked; the umbrella-shaped claw insertion hole 122 is also provided with a retaining ring 34 and a claw protection tube 35 that match the umbrella-shaped claw 32. The claw of the umbrella-shaped claw 32 passes through the retaining ring 34 and extends into the claw protection tube 35. When the locking head 311 of the locking pull rod 31 enters the claw space of the umbrella-shaped claw 32, The claw of the umbrella-shaped claw 32 is expanded by the locking head 311 and clamped on the retaining ring 34; the upper end of the locking rod 31 is fixedly connected to the rod fixing rod 36, and the upper end of the rod fixing rod 36 extends upward and passes through the fixing rod through hole corresponding to the fixture cover 13. The rod fixing rod 36 has an annular protrusion, which is used to abut the upper end of the rod compression spring 33 and limit the rod fixing rod 36 and the locking rod 31 from sliding out of the rod step mounting hole 112.

[0056] In this embodiment, when the fixture locking assembly is working, after the battery workpiece 9 is placed inside the fixture, the fixture needs to be locked. First, the umbrella-shaped claw 32 sleeved on the lower end of the locking rod 31 is inserted into the umbrella-shaped claw insertion hole 122. While inserting the umbrella-shaped claw 32, a thrust is applied to the locking rod 31. The thrust pushes the locking rod 31 to move in the rod step mounting hole 112 in a direction away from the umbrella-shaped claw 32, so that the locking head 311 of the locking rod 31 comes out of the claw space of the umbrella-shaped claw 32, and the umbrella-shaped claw 32 is in an unexpanded state. At this time, the umbrella-shaped claw 32 and the locking rod 31 can be smoothly inserted into the umbrella-shaped claw insertion hole 122. When inserted into place, release the external thrust, and under the elastic force of the pull rod compression spring 33, the locking pull rod 31 moves upward, and synchronously, the locking head 311 enters the claw space inside the umbrella-shaped claw 32 and expands the claw of the umbrella-shaped claw 32. The expanded claw of the umbrella-shaped claw 32 is clamped in the retaining ring 34 and the umbrella-shaped claw 32 and the retaining ring 34 are locked with each other, thereby realizing the locking function of the jig upper cover 11 and the jig lower cover 12.

[0057] When unlocking is required, a thrust is applied to the pull rod fixing rod 36, and the thrust overcomes the elastic force of the pull rod compression spring 33 and drives the locking pull rod 31 to move downward until the locking head 311 of the locking pull rod 31 slides out of the claw space inside the umbrella-shaped claw 32. After the locking head 311 leaves, the umbrella-shaped claw 32 uses its own elasticity to reset and shrink. The shrunk umbrella-shaped claw 32 and the retaining ring 34 are released from the locking state. At this time, the upper capsule assembly can be separated from the lower capsule assembly.

[0058] The above is the locking and unlocking process of the fixture, and the whole process is easy to operate.

[0059] The side of the jig cover 13 is provided with a first jig rolling bearing 51, and the side of the jig cover 13 and the jig bottom cover 14 is provided with a jig limiting block 53. The first jig rolling bearing 51 can realize the up and down sliding function of the jig, and the jig limiting block 53 can limit the jig.

[0060] The injection cup assembly 2 includes a injection cup 21 and a injection nozzle 22. The injection nozzle 22 is installed at the lower port of the injection cup 21 through an anti-slip ring 23. Sealing rings are provided between the fixture cover 13 and the fixture upper cover 11 and between the fixture lower cover 12 and the fixture bottom cover 14.

[0061] Based on the above-mentioned capsule battery fixture, the utility model also provides:

[0062] A liquid filling machine, comprising the capsule type battery fixture.

[0063] Embodiment 2:

[0064] Reference Figure 8-13 This embodiment is basically the same as Embodiment 1, except that:

[0065] The jig upper cover 11 is provided with an upper cover through hole 113 which passes through from top to bottom, and the jig lower cover 12 is provided with a lower cover through hole 123. The jig locking assembly comprises a lock tube sleeve 41 installed at the lower end of the upper cover through hole 113, and a lock rod tube 42, a lock rod 43, and a lock rod compression spring 44 installed in the lower cover through hole 123. The lock rod 43 has a hole which partially penetrates into the lock rod tube 42. The upper end of the lock rod tube 42 is provided with a plurality of lock bead mounting holes 421 which pass through along the thickness direction thereof. The lock bead mounting holes 421 are provided with lock bead mounting holes 421. 45, the upper end of the locking rod 43 extending into the locking rod tube 42 has a pointed structure 431, and the inner wall of the locking tube sleeve 41 has a locking position for matching the locking bead 45. The pointed structure 431 can force the locking bead 45 to slide outward in the locking bead mounting hole 421 under the elastic force of the locking rod compression spring 44 and make the locking bead 45 at least partially inserted into the locking position of the locking tube sleeve 41 to achieve mutual locking of the locking tube sleeve 41 and the locking rod 43, and finally make the upper cover 11 of the jig and the lower cover 12 of the jig locked with each other. The locking rod compression spring 44 is installed at the bottom of the lower cover through hole 123, and the lower end of the locking rod compression spring 44 is pressed against the surface of the jig bottom cover 14 or the corresponding step position inside the lower cover through hole 123, and the upper end of the locking rod compression spring 44 is pressed against the lower end of the locking rod 43, and the lower end of the locking rod 43 has an insertion portion, and the insertion portion is inserted into the upper end of the locking rod compression spring 44; the middle position of the locking rod 43 has a limiting step position, and the limiting step position is used to limit the locking rod 43 from sliding out of the locking rod tube 42, and the locking position inside the lock tube sleeve 41 is an annular recess, and an inclined structure is provided at the annular recess, through which the locking bead 45 can be easily introduced into the locking bead mounting hole 421 so as to realize the quick disassembly function of the jig upper cover 11 and the jig lower cover 12.

Under the pressure of the thimble, the locking rod 43 overcomes the elastic force of the locking rod compression spring 44 and moves downward, so that the upper end of the locking rod 43 slides out of the locking rod tube 42. At this time, the locking rod tube 42 can be inserted into the locking tube sleeve 41 and inserted into place. After the locking rod tube 42 is inserted into place, the external thimble is released, and under the elastic force of the locking rod compression spring 44, the pointed structure 431 on the upper part of the locking rod 43 is inserted into the position corresponding to the locking bead installation hole 421, and the pointed structure 431 forces the locking bead 45 to move outward, and the locking bead 45 has a partial structure that is inserted into the locking position inside the locking tube sleeve 41. At this time, the locking tube sleeve 41 and the locking rod tube 42 are locked with each other, thereby realizing the mutual locking of the jig upper cover 11 and the jig lower cover 12 .

[0067] When unlocking is required, the upper end of the locking rod 43 is pressed by a pin, and the locking rod 43 overcomes the elastic force of the locking rod compression spring 44 and moves downward. After moving into position, the pointed structure 431 of the locking rod 43 leaves the position corresponding to the locking bead mounting hole 421. At this time, under the action of the inclined structure, the locking bead 45 will enter the locking bead mounting hole 421, and the locking tube sleeve 41 and the locking rod tube 42 will be released from the locking tube sleeve 41. The locking rod tube 42 can be smoothly pulled out of the locking tube sleeve 41, thereby realizing the unlocking and separation of the jig upper cover 11 and the jig lower cover 12.

[0069] Embodiment 3:

[0070] Reference Figure 14-19 This embodiment is basically the same as Embodiment 1, except that:

[0071] The capsule-type jig described in this embodiment is used in the application scenario of blade-shaped batteries. Specifically, in this embodiment, the jig upper cover 11 and the jig cover 13 are integrally formed parts, and a through hole 114 is provided on the jig upper cover 11, and a buckle mounting hole is provided on the jig lower cover 12. The jig locking assembly includes a locking pin 510 provided in the through hole 114 and a locking plug 520 sleeved on the lower end of the locking pin 510.

[0076] Embodiment 4:

[0077] Reference Figure 20-25 This embodiment is basically the same as Embodiment 1, except that:

[0078] The capsule-type jig described in this embodiment is used in the application scenario of square shell batteries. Specifically, in this embodiment, the jig locking assembly includes a steel ball buckle 61 installed on the jig upper cover 11 and a steel ball fixing sleeve 62 and a pull rod guide sleeve 63 arranged on the jig lower cover 12. The steel ball fixing sleeve 62 has a plurality of steel ball mounting holes arranged on it, and a locking steel ball 64 is arranged at the steel ball mounting hole. A steel ball push rod 65 is movably inserted in the steel ball fixing sleeve 62, and a push rod pull rod 66 is movably arranged in the pull rod guide sleeve 63. The outer sleeve of the steel ball push rod 65 is provided with a push rod compression spring 67 for forcing the steel ball push rod 65 to push toward the locking steel ball 64. The aperture of the steel ball mounting hole is smaller than the diameter of the locking steel ball 64, so that the locking steel ball 64 will not fall out of the steel ball mounting hole. When the push rod compression spring 67 drives the end of the steel ball push rod 65 to be inserted into the steel ball fixing sleeve 62 and exceeds the preset depth, the steel ball push rod 65 can force part of the structure of the positioning steel ball 64 to protrude along the steel ball mounting hole to the outside of the steel ball fixing sleeve 62 and be clamped on the steel ball buckle 61 through the protruding part of the positioning steel ball 64 to realize the mutual locking function of the jig upper cover 11 and the jig lower cover 12.

[0079] A battery clamp 8 is disposed inside the jig lower cover 12 , and the battery clamp 8 is used to clamp the battery workpiece 9 .

[0080] In this embodiment, the jig upper cover 11 and the jig sealing cover 13 are integrally formed, and the jig lower cover 12 and the jig bottom cover 14 are integrally formed parts.

[0081] In specific applications, when the jig upper cover 11 and the jig lower cover 12 need to be locked, the push rod pull rod 66 is pulled, and the steel ball push rod 65 is pulled by the push rod pull rod 66 to move, so that the steel ball push rod 65 and the positioning steel ball 64 are separated from each other. After the steel ball push rod 65 and the positioning steel ball 64 are separated from each other, the positioning steel ball 64 can be retracted along the steel ball installation hole, and will not hinder the steel ball fixing sleeve 62 from being inserted into the steel ball buckle 61. At this time, the steel ball fixing sleeve 62 is inserted into the corresponding opening on the steel ball buckle 61 and passes through the opening. After the position corresponding to the positioning steel ball 64 passes over the opening on the steel ball buckle 61, the push rod pull rod 66 is loosened. Under the elastic force of the push rod compression spring 67, the steel ball push rod 65 moves toward the positioning steel ball 64. When the steel ball push rod 65 moves to the preset position, the end of the steel ball push rod 65 forces part of the structure of the positioning steel ball 64 to protrude along the steel ball mounting hole to the outside of the steel ball fixing sleeve 62, and the protruding part of the positioning steel ball 64 is clamped on the steel ball buckle 61, thereby realizing the mutual locking function of the jig upper cover 11 and the jig lower cover 12.
