Abstract

The application discloses a tool for sealing lithium batteries, which comprises a base and a sealing machine arranged on the top of the base. The top of the base is provided with a placing device, which comprises a placing table, placing grooves, a pressing plate, connecting rods, springs and fasteners. The placing grooves, the pressing plate, the connecting rods, the springs and the fasteners are arranged in three groups, and the three groups of the placing grooves, the pressing plate, the connecting rods, the springs and the fasteners are arranged on the placing table in an array. The fasteners comprise clamping plates, and the clamping plates penetrate through the inner sides of the placing grooves on the top of the placing table and are connected with the placing table in a sliding mode. When the pressing plate is moved downward, the pressing plate can move to one side of the center of the placing groove by abutting the cross rod, the spring and the clamping plate through the supporting rod, so that the lithium battery is clamped and fixed. When the lithium battery is large, the clamping plate contacts the lithium battery, and the pressing plate continues to move downward. At this time, the cross rod and the clamping plate can extrude the spring, so that the normal downward movement of the pressing plate is not affected.

Description

Technical Field

[0001] This invention relates to the field of lithium battery sealing, and in particular to a tooling for sealing lithium batteries. Background Technology

[0002] With societal development, electronic products are widely used in daily life, and mobile devices such as cameras and mobile phones are rapidly becoming commonplace. The demand for these devices is increasing, and so are the requirements for rechargeable batteries. Lithium batteries, with their high capacity, long lifespan, safety, and eco-friendliness, have become the undisputed power source for these mobile devices. As the number of mobile devices grows, the demand for lithium batteries is also increasing, making the sealing process a crucial step in lithium battery production.

[0003] In existing technologies, when sealing lithium batteries, it is necessary to fix the lithium batteries to prevent leakage. However, current sealing machines can only fix lithium batteries of the same size and specifications, which has certain drawbacks. Moreover, the sealing effect is not good. Therefore, we propose a tooling for sealing lithium batteries. Summary of the Invention

[0004] The main objective of this invention is to provide a tooling for sealing lithium batteries, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a tooling for sealing lithium batteries, comprising a base and a sealing machine disposed on top of the base. A placement device is disposed on top of the base, and a limiting component is disposed inside the placement device. The placement device includes:

[0006] A placement platform, which is fixed to the top of the base, has a placement slot on its top;

[0007] A pressure plate, which penetrates the inner side of the placement groove at the top of the placement platform and is slidably connected to the placement platform;

[0008] A connecting rod is fixed to the bottom of the pressure plate. The connecting rod passes through the inner side of the placement groove at the top of the placement platform and is slidably connected to the placement platform.

[0009] Spring 1, a spring 1 is fixed on the inner wall of the placement platform;

[0010] Fasteners are provided inside the placement platform and on the inner side of the placement slot.

[0011] Optionally, the placement device includes a placement platform, a placement slot, a pressure plate, a connecting rod, a spring, and fasteners. The placement slot, pressure plate, connecting rod, spring, and fasteners are all provided in three sets, and the three sets of placement slots, pressure plates, connecting rods, springs, and fasteners are arranged in an array on the placement platform, so that three sets of lithium batteries can be sealed at one time.

[0012] Optionally, the fastener includes a clamping plate that penetrates the inner side of the placement slot at the top of the placement platform and is slidably connected to the placement platform. The clamping plate is penetrated by a crossbar and is slidably connected to the crossbar. A second spring is fixed to the side of the clamping plate away from the center of the placement slot. The end of the second spring away from the clamping plate is fixed to the crossbar. A support rod is hinged to the end of the crossbar away from the clamping plate. The end of the support rod away from the crossbar is hinged to the top of the pressure plate. When the pressure plate is pushed downward, the pressure plate can push the crossbar, the second spring, and the clamping plate towards the center of the placement slot through the support rod, thereby clamping and fixing the lithium battery. When the lithium battery is large, after the clamping plate contacts the lithium battery, the pressure plate continues to move downward. At this time, the crossbar and the clamping plate can squeeze the second spring without affecting the normal downward movement of the pressure plate.

[0013] Optionally, the limiting component includes a rectangular block, which is fixed to the bottom of the connecting rod. A groove is provided on the left side of the rectangular block, and a chuck is slidably installed on the inner side of the groove on the left side of the rectangular block. A spring is fixed on the right side of the chuck, and the end of the spring away from the chuck is fixed on the inner side of the groove on the left side of the rectangular block.

[0014] Optionally, a fixing rod is fixed on the inner wall of the placement platform, a locking block is fixed on the top of the fixing rod, the fixing rod passes through the slider and is slidably connected to the slider, and a spring is fixed at the bottom of the slider, with the end of the spring away from the slider fixed to the fixing rod.

[0015] Optionally, one end of the spring away from the placement platform is fixed to the top of the rectangular block.

[0016] Optionally, the bottom of the locking block has a groove that matches the slider. When the pressure plate is pushed downwards, the pressure plate moves downwards along with the connecting rod and the rectangular block. The rectangular block moves downwards along with the locking knife and the spring. After the locking knife moves downwards a certain distance, it is pushed by the locking block, causing it to move to the right. When the locking knife reaches the bottom of the locking block, it pops out and blocks against the bottom of the locking block under the action of the spring, thus limiting the pressure plate. When the pressure plate is pushed downwards again, the pressure plate moves downwards along with the connecting rod and the rectangular block. The rectangular block moves downwards along with the locking knife and the spring. The chuck moves downwards and is pushed to the right by the slider. When the chuck reaches the bottom of the slider, it pops out and rests against the bottom of the slider under the action of spring three. At this point, no downward pressure is applied to the pressure plate. Under the action of spring one, the pressure plate, connecting rod, and rectangular block move upwards. The rectangular block moves upwards along with the chuck and spring three. The chuck moves upwards against the slider. When the slider is embedded in the groove at the bottom of the chuck block, the slider and the chuck block form a whole. The slider and the chuck block move the chuck block to the right, causing the chuck block to separate from the slider and the chuck block, thereby releasing the limit on the pressure plate.

[0017] Optionally, the sealing machine is provided with a rotating compaction assembly, which includes a cylinder that passes through the pressure head of the sealing machine. The top of the cylinder is penetrated by a rotating rod and slidably connected to the rotating rod. The top of the rotating rod is rotatably mounted on the inner wall of the pressure head of the sealing machine. A spring is fixed to the top of the cylinder, and the end of the spring away from the cylinder is fixed to the rotating rod. A sliding rod is fixed on the inner wall of the pressure head of the sealing machine.

[0018] Optionally, the surface of the cylinder is provided with an arc-shaped groove, and the end of the slide rod away from the sealing machine pressure head is slidably installed on the inner side of the arc-shaped groove on the surface of the cylinder. When the slide rod slides up and down in the arc-shaped groove on the surface of the cylinder, the cylinder can be rotated.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) When the pressure plate is pushed down, it can move to the side of the center of the placement slot by pushing the crossbar, spring 2 and clamping plate through the support rod, so as to clamp and fix the lithium battery. When the lithium battery is large, after the clamping plate contacts the lithium battery, the pressure plate continues to move down. At this time, the crossbar and clamping plate can squeeze the spring 2, which will not affect the normal downward movement of the pressure plate.

[0021] (2) When the sealing machine is started, the sealing machine presses down as a whole. When the cylinder contacts the top of the lithium battery, the cylinder is pushed and cannot move. At this time, the sealing machine continues to move down, and the slide bar slides down the arc groove on the surface of the cylinder, causing the cylinder to rotate. This, together with the pressure head of the sealing machine, better seals the lithium battery.

[0022] (3) The sealing tool for the lithium battery is used to start the sealing machine to move upward and reset after sealing. The lithium battery is no longer pressed down. Under the action of spring one, the pressure plate pushes the lithium battery upward and pops it out, making it convenient for staff to take the lithium battery out. Attached Figure Description

[0036] Reference Figures 1 to 7 The present invention proposes a tooling for sealing lithium batteries, including a base 1 and a sealing machine 2 disposed on the top of the base 1. A placement device 3 is disposed on the top of the base 1, and a limiting component 4 is disposed inside the placement device 3.

[0037] In this embodiment of the invention, the placement device 3 includes:

[0038] Placement platform 31 is fixed to the top of base 1, and placement slot 32 is provided on the top of placement platform 31;

[0039] Pressure plate 33 penetrates the inner side of the placement groove 32 at the top of the placement platform 31 and is slidably connected to the placement platform 31;

[0040] The bottom of the pressure plate 33 is fixed with a connecting rod 34. The connecting rod 34 passes through the inside of the top placement groove 32 of the placement platform 31 and is slidably connected to the placement platform 31.

[0041] Spring 35 is fixed on the inner wall of the placement platform 31;

[0042] Fastener 36 is provided inside the placement platform 31 and on the inner side of the placement slot 32.

[0043] Specifically, the placement device 3 includes a placement platform 31, a placement groove 32, a pressure plate 33, a connecting rod 34, a spring 35, and a fastener 36. The placement groove 32, pressure plate 33, connecting rod 34, spring 35, and fastener 36 are all provided in three sets, and the three sets of placement groove 32, pressure plate 33, connecting rod 34, spring 35, and fastener 36 are arranged in an array on the placement platform 31, so that three sets of lithium batteries can be sealed at one time.

[0044] In one embodiment of the present invention, the fastener 36 includes a clamping plate 361, which penetrates the inner side of the placement groove 32 at the top of the placement platform 31 and is slidably connected to the placement platform 31. A crossbar 362 penetrates the clamping plate 361 and is slidably connected to it. A second spring 363 is fixed to the side of the clamping plate 361 away from the center of the placement groove 32. The end of the second spring 363 away from the clamping plate 361 is fixed to the crossbar 362. A support rod 364 is hinged to the end of the crossbar 362 away from the clamping plate 361. One end of the crossbar 362 is hinged to the top of the pressure plate 33. When the pressure plate 33 is pushed down, it can move towards the center of the placement slot 32 by pushing the crossbar 362, spring 363, and clamping plate 361 through the support rod 364, thereby clamping and fixing the lithium battery. When the lithium battery is large, after the clamping plate 361 contacts the lithium battery, the pressure plate 33 continues to move down. At this time, the crossbar 362 and clamping plate 361 can squeeze the spring 363 without affecting the normal downward movement of the pressure plate 33.

[0045] Please continue reading. Figure 1-7 The limiting component 4 includes a rectangular block 41, which is fixed to the bottom of the connecting rod 34. A groove is provided on the left side of the rectangular block 41. A chuck 42 is slidably installed on the inner side of the groove on the left side of the rectangular block 41. A spring 43 is fixed on the right side of the chuck 42. The end of the spring 43 away from the chuck 42 is fixed to the inner side of the groove on the left side of the rectangular block 41. A fixing rod 44 is fixed on the inner wall of the placement platform 31. A chuck 45 is fixed on the top of the fixing rod 44. The fixing rod 44 passes through the slider 46 and is slidably connected to the slider 46. A spring 47 is fixed on the bottom of the slider 46. The end of the spring 47 away from the slider 46 is fixed to the fixing rod 44.

[0046] In addition, the end of spring 35 away from the placement platform 31 is fixed to the top of rectangular block 41.

[0047] To release the limiting effect on the pressure plate 33, the bottom of the locking block 45 has a groove that matches the slider 46. When the pressure plate 33 is pushed downwards, it moves downwards along with the connecting rod 34 and the rectangular block 41. The rectangular block 41 moves downwards along with the chuck 42 and the spring 43. After the chuck 42 moves downwards a certain distance, it is pushed by the locking block 45, causing it to move to the right. When the chuck 42 reaches the bottom of the locking block 45, it pops out and presses against the bottom of the locking block 45 under the action of the spring 43, thus limiting the pressure plate 33. When the pressure plate 33 is pushed downwards again, it moves downwards along with the connecting rod 34 and the rectangular block 41. The rectangular block 41 moves downwards along with the chuck 42 and the spring 43. Moving downwards, the chuck 42 moves downwards and is pushed to the right by the slider 46. When the chuck 42 moves to the bottom of the slider 46, under the action of the spring 33, the chuck 42 pops out and presses against the bottom of the slider 46. At this time, no downward pressure is applied to the pressure plate 33. Under the action of the spring 1 35, the pressure plate 33, the connecting rod 34 and the rectangular block 41 move upwards. The rectangular block 41 moves upwards with the chuck 42 and the spring 33. The chuck 42 presses against the slider 46 and moves upwards. When the slider 46 is embedded in the groove at the bottom of the chuck block 45, the slider 46 and the chuck block 45 form a whole. The slider 46 and the chuck block 45 move the chuck 42 to the right, so that the chuck 42 separates from the slider 46 and the chuck block 45, thereby releasing the limit on the pressure plate 33.

[0048] In an embodiment of the present invention, a rotating compaction assembly 5 is provided on the sealing machine 2. The rotating compaction assembly 5 includes a cylinder 51, which passes through the pressure head of the sealing machine 2. The top of the cylinder 51 is penetrated by a rotating rod 52 and is slidably connected to the rotating rod 52. The top of the rotating rod 52 is rotatably mounted on the inner wall of the pressure head of the sealing machine 2. A spring 53 is fixed on the top of the cylinder 51. The end of the spring 53 away from the cylinder 51 is fixed to the rotating rod 52. A sliding rod 54 is fixed on the inner wall of the pressure head of the sealing machine 2.

[0049] In an embodiment of the present invention, an arc-shaped groove is provided on the surface of the cylinder 51, and the end of the slide rod 54 away from the pressure head of the sealing machine 2 is slidably installed on the inner side of the arc-shaped groove on the surface of the cylinder 51. When the slide rod 54 slides up and down in the arc-shaped groove on the surface of the cylinder 51, the cylinder 51 can be rotated.

[0050] In this invention, when in use, the lithium battery that needs to be sealed is placed into the placement slot 32 at the top of the placement platform 31, and the lithium battery is pressed down. The lithium battery moves downward against the pressure plate 33. The pressure plate 33 can move towards the center of the placement slot 32 by the support rod 364 against the cross bar 362, the second spring 363, and the clamping plate 361, thereby clamping and fixing the lithium battery. When the lithium battery is large, after the clamping plate 361 contacts the lithium battery, the pressure plate 33 continues to move downward. At this time, the cross bar 362 and the clamping plate 361 can squeeze the second spring 363 without affecting the normal downward movement of the pressure plate 33.

[0051] When the pressure plate 33 is pushed downward, the pressure plate 33 moves downward along with the connecting rod 34 and the rectangular block 41. The rectangular block 41 moves downward along with the chuck 42 and the spring 43. After the chuck 42 moves downward a certain distance, it is pushed by the chuck block 45, causing the chuck 42 to move to the right. When the chuck 42 moves to the bottom of the chuck block 45, under the action of the spring 43, the chuck 42 pops out and pushes against the bottom of the chuck block 45, thereby limiting the pressure plate 33.

[0052] When the sealing machine 2 is started, the sealing machine 2 presses downward as a whole. When the cylinder 51 contacts the top of the lithium battery, the cylinder 51 is pushed and cannot move. At this time, the sealing machine 2 continues to move downward, and the slide bar 54 slides down the arc-shaped groove on the surface of the cylinder 51, causing the cylinder 51 to rotate. This, together with the pressure head of the sealing machine 2, better seals the lithium battery.

[0053] At this time, the sealing machine 2 pushes the lithium battery downward a certain distance, the lithium battery pushes the pressure plate 33 downward, the pressure plate 33 moves downward with the connecting rod 34 and the rectangular block 41, the rectangular block 41 moves downward with the cutter 42 and the spring 43, the cutter 42 moves downward and is pushed to the right by the slider 46. When the cutter 42 moves to the bottom of the slider 46, under the action of the spring 43, the cutter 42 pops out and pushes against the bottom of the slider 46. At this time, no downward pressure is applied to the pressure plate 33. Under the action of the spring 35, the pressure plate 33, the connecting rod 34 and the rectangular block 41 move upward. The rectangular block 41 moves upward with the cutter 42 and the spring 43, the cutter 42 pushes against the slider 46 and moves upward. When the slider 46 is embedded in the groove at the bottom of the cutter 45, the slider 46 and the cutter 45 form a whole. The slider 46 and the cutter 45 move the cutter 42 to the right, so that the cutter 42 separates from the slider 46 and the cutter 45, thereby releasing the limit on the pressure plate 33.

[0054] After sealing is completed, start the sealing machine 2 to move upward and reset. The lithium battery is no longer pressed down. Under the action of spring 35, the pressure plate 33 pushes the lithium battery upward and pops it out, making it convenient for staff to take the lithium battery out.

[0055] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
