Description

Technical Field

[0001] The invention relates to the technical field of lithium battery production and manufacturing, and in particular to a lithium battery dry gel buffer machine. Background Art

[0002] Lithium batteries are generally composed of battery cells, battery protection circuit boards, output terminals and plastic battery casings. The battery cells contain positive and negative electrodes, diaphragms and electrolytes, and are packaged in metal casings. At present, as electronic devices are becoming thinner and smaller, lithium batteries as power sources must also adapt to the development requirements of these devices, and further reduce the size of the battery while keeping the capacity unchanged.

[0003] In order to reduce the volume of the battery, a lithium battery structure without a battery shell is now basically adopted. The structure is to add end caps and bottom films to the front and rear ends of the battery cell respectively. The end caps are made by integral glue injection or glue point bonding, while the rear end of the battery cell and the plastic battery bottom film are only made by glue point bonding. After glue point bonding, the lithium battery needs to be dry glue treated.

[0047] Working principle of the present invention:

[0048] As shown in the figure, in this embodiment, the double-layer flow channel device 2 can accommodate 10 material box mechanisms 4 at a time, and each material box mechanism 4 can accommodate 16 brackets 43 (the brackets 43 have lithium batteries with glue applied inside); 5 upper flow channel mechanisms 21 are arranged (the 5 material box mechanisms 4 contain a number of brackets 43, and the brackets 43 have lithium batteries with glue applied inside, that is, the 5 material box mechanisms 4 on the upper flow channel mechanism 21 are used for dry glue work on lithium batteries, and the dry glue standing time is 15 minutes, that is, 80 lithium batteries can be dry glued at one time, with high working efficiency), and the lower flow channel mechanism 22 is also arranged with 5 material box mechanisms 4 (the 5 material box mechanisms 4 are empty for easy recycling), and at the same time, the first material box ejection mechanism 12 also places an extra material box mechanism 4 as a backup, that is, the whole set of dry glue cache machine can accommodate 11 material box mechanisms 4 at a time; in addition, the working principle of the loading device 1 is similar to that of the unloading device 3, and the working principle of the upper loading device 1 is mainly explained below.

[0049] During operation, the current working state as shown in the figure is used for explanation. After all the lithium batteries in the five material box mechanisms 4 on the upper flow channel mechanism 21 have completed the drying work (after standing for 15 minutes), the loading translation module 141 (including the linear motor module) and the loading lifting module 142 (including the linear motor module) cooperate with each other to drive the suction cup module (including the suction cup body for sucking the bracket 43 and the suction cup cylinder for driving the suction cup body to work) to carry the bracket 43 carrying the lithium batteries after dispensing glue from the upper workbench, and place them one by one in the material box mechanism 4 located at the top of the first material box ejection mechanism 12 at this time (for the convenience of explanation, the material box mechanism 4 is named the first material box mechanism 4, and this name is used instead in the following description). The material storage rack 42 of the material box mechanism 4 is provided with a horizontal clamping position to facilitate the placement of the bracket 43. The rack 43 is provided with isolation columns to ensure that adjacent racks 43 will not come into direct contact with each other; when the storage rack 42 of the first material box mechanism 4 is filled with 16 racks 43, at this time, the first lifting cylinder 125 located below the base 41 of the first material box mechanism 4 drives its cylinder shaft to be inserted into the first limiting hole corresponding to it (the first limiting hole is located at the bottom of the base 41), which can ensure that the first material box mechanism 4 will not slide along the first guide rail 124 via the first roller 44 at will, thereby improving the stability of the first material box mechanism 4, and then, the first motor 132 drives the first screw module 131 via the first ejection seat 121 (the outer side of the first ejection seat 121 is drivingly connected to the first screw module 131) to drive the first material box mechanism 4 to rise until the first guide rail 124 is level with the second guide rail 211 located at the top of the runner rack 23.

[0050] At this time, the cylinder shaft of the first limiting cylinder 212 located on one side of the material box mechanism 4 at the top of the runner frame 23 near one end of the unloading device 3 is in an extended state. At the same time, the cylinder shaft of the second lifting cylinder 213 located below the material box mechanism 4 at the other end of the runner frame 23 is inserted into the corresponding first limiting hole of the material box mechanism 4 (that is, the five material box mechanisms 4 located at the top of the runner frame 23 are limited between the first limiting cylinder 212 and the second lifting cylinder 213;). In this way, the material box mechanisms 4 at both ends can be fixed on the second guide rails 211, thereby ensuring the stability of the five material box mechanisms 4. When the first guide rail 124 under the first material box mechanism 4 rises to a position flush with the second guide rail 211, the first limiting cylinder 212 located at one end of the top of the runner frame 23 first drives its cylinder shaft to be retracted, and then the second lifting cylinder 213 drives its cylinder shaft to be retracted from the first limiting hole, and then the first translation cylinder 123 drives the first material box mechanism 4 to slide along the first guide rail 124 toward the second guide rail 211 (at this time, the cylinder shaft of the first lifting cylinder 125 is inserted into the first limiting hole of the first material box mechanism 4, so it can drive the first material box mechanism 4 to slide When the first roller 44 of the first material box mechanism 4 contacts the second guide rail 211, the first lifting cylinder 125 drives its cylinder shaft to retract from the first limiting hole, and then the first material box mechanism 4 continues to slide along the second guide rail 211 driven by the inertial force. At this time, the five material box mechanisms 4 located on the second guide rail 211 are pushed by the first material box mechanism 4 to slide along the second guide rail 211 to the lower feeding device 3; at the same time, the second lifting mechanism has driven the second material box pushing mechanism to rise to a position flush with the upper flow channel mechanism 21, so the material box mechanism 4 close to the lower feeding device 3 (for the convenience of explanation) , the material box mechanism 4 is named as the second material box mechanism 4, and this name is used instead in the following descriptions) continues to slide along the third guide rail to the second material box pushing mechanism under thrust (at this time, the first limiting cylinder 212 drives its cylinder shaft to extend, blocking the next material box mechanism 4 from continuing to slide). At the same time, the first material box mechanism 4 has slid to the top of one end of the upper channel mechanism 21, and the second lifting cylinder 213 at one end of the upper channel mechanism 21 drives its cylinder shaft to be inserted into the first limiting hole of the corresponding first material box mechanism 4 to ensure the stability of the 5 material box mechanisms 4 located on the upper channel mechanism 21 at this time.

[0051] When the second material box mechanism 4 is at the top of the second ejection seat of the second material box ejection mechanism, the third lifting cylinder located at the top of the second sliding module drives its cylinder shaft to be inserted into the first limit hole of the second material box mechanism 4 to prevent the second material box mechanism 4 from sliding along the third guide rail; then, the unloading translation module (including the linear motor module) and the unloading lifting module (including the linear motor module) cooperate with each other to drive the unloading suction cup module (including the suction cup body for sucking the bracket 43 and the suction cup cylinder driving the suction cup body to work) to move the bracket 43 in the second material box mechanism 4 (the lithium battery in the bracket 43 has completed the drying glue work) to the next workbench one by one; when all the brackets 43 in the second material box mechanism 4 are completely moved out, the second motor drives the second screw rod module (the second screw rod module is drivingly connected to the second ejection seat) to drive the second material box ejection mechanism and the second material box mechanism 4 to do a downward movement until the third guide rail is reached. The rail is level with the second guide rail 211 located on the inner side of the bottom plate of the runner frame 23, and the second translation cylinder drives the second material box mechanism 4 to slide along the third guide rail toward the second guide rail 211 through the second sliding module and the third lifting cylinder. When the first roller 44 of the second material box mechanism 4 contacts the second guide rail 211, the third lifting cylinder drives its cylinder shaft to be retracted from the first limiting hole of the second material box mechanism 4. Therefore, the second material box mechanism 4 continues to slide along the second guide rail 211 under the drive of inertia. At this time, the first limiting cylinder 212 located at one end of the lower runner mechanism 22 close to the feeding device 1 drives its cylinder shaft to be retracted. At the same time, the second lifting cylinder 213 at the other end of the lower runner mechanism 22 is retracted from the first limiting hole of the corresponding material box mechanism 4. Therefore, the 5 empty material box mechanisms 4 on the lower runner mechanism 22 continue to slide along the second guide rail 211 under the push of the second material box mechanism 4.

[0052] At this time, the first lifting mechanism 13 has driven the first material box ejection mechanism 12 to descend to a position flush with the lower flow channel mechanism 22, so the material box mechanism 4 on the lower flow channel mechanism 22 close to the loading device 1 can be moved to the first material box ejection mechanism 12, and the second material box mechanism 4 can be moved to the lower flow channel mechanism 22. At the same time, the first limiting cylinder 212 located at one end of the lower flow channel mechanism 22 drives its cylinder shaft to extend to prevent the next material box mechanism 4 from continuing to slide, and the second lifting cylinder 213 drives its cylinder shaft to be inserted into the first limiting hole of the corresponding second material box mechanism 4 to ensure the stability of the 5 empty material box mechanisms 4 located in the lower flow channel mechanism 22 at this time; repeat the above steps to realize the drying of the lithium batteries in the new 5 material box mechanisms 4 and the repeated recycling of the material box mechanisms 4.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
