DETAILED DESCRIPTION

[0034] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention. Example 1

[0035] A lithium battery packaging device, such as Figure 1 and Figure 2As shown, it includes a bracket 1, an electric push rod 2, a fixed rod 21, an extrusion plate 3, a placement box 4, a stabilizing mechanism 5 and a pressing mechanism 6. The left and right sides of the upper part of the bracket 1 are connected with the fixed rod 21, the electric push rod 2 is connected between the sides of the upper part of the fixed rod 21 that are close to each other, the lower side of the telescopic rod of the electric push rod 2 is connected with the extrusion plate 3, the upper part of the bracket 1 is connected with the placement box 4, and three placement grooves are evenly opened on the placement box 4. A stabilizing mechanism 5 is arranged between the fixed rods 21, and the stabilizing mechanism 5 is used to clamp the cap and the lithium battery front and back, and push the cap toward the center direction of the positive electrode of the lithium battery. A pressing mechanism 6 is arranged on the lower side of the extrusion plate 3, and the pressing mechanism 6 is used to rotate and press one circle with the pole on the cap as the center, so that the cap can be pressed and installed more smoothly.

[0036] Figure 1 , Figure 3 and Figure 4 As shown, the stabilizing mechanism 5 includes a first slide rail 51, a sliding frame 52, a sliding member 53, a first telescopic spring 54 and a first bidirectional screw 55. The first slide rail 51 is connected to the side close to each other at the lower part of the fixing rod 21. The first bidirectional screw 55 is rotatably connected in the first slide rail 51 on the left. The front and rear sides of the first bidirectional screw 55 are threadedly connected to the sliding frame 52. The sliding frames 52 are slidably connected to the first slide rail 51. The sliding frames 52 are symmetrically distributed front to back. Three sliding members 53 are evenly slidably connected to the side close to each other of the sliding frames 52. The sides close to each other of the sliding members 53 on different sliding frames 52 are all made of soft materials. The first telescopic spring 54 is connected between the lower side of the sliding member 53 and the adjacent sliding frame 52. The sliding member 53 cooperates with the sliding frame 52 to clamp the cap and the lithium battery front and back.

[0037] Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the pressing mechanism 6 includes an extrusion rod 61, a space cam 62, a telescopic member 63, a first roller 64, a second telescopic spring 65 and a fixing member 66. The lower side of the extrusion plate 3 is slidably connected with the telescopic member 63. The telescopic member 63 and the sliding member 53 are both extruded and matched. The left and right sides of the upper part of the telescopic member 63 and the extrusion plate 3 are both wound with a second telescopic spring 65. The second telescopic spring 65 is wound around the telescopic member 63. The lower part of the telescopic member 63 is evenly rotatably connected with three space cams 62. The lower part of the extrusion plate 3 is evenly connected with three The extrusion rods 61 are respectively located on the upper left side of the adjacent space cams 62, and the extrusion rods 61 and the adjacent space cams 62 are threadedly connected through a threaded groove. The lower part of the space cams 62 is connected with a fixing part 66, and the right side of the fixing part 66 is rotatably connected with a first roller 64. The extrusion rods 61 squeeze the space cams 62, so that the space cams 62 drive the fixing part 66 and the first roller 64 to rotate along the threaded groove, and the first roller 64 presses a circle of the cap to prevent the cap from tilting on one side.

[0038] The lithium battery cap is composed of a pole and an annular covering member, and the pole is located in the middle area of ​​the annular covering member, so that the cap forms a shape with a middle bulge and four sides being flat. When the lithium battery packaging device is used to complete the packaging of the lithium battery, the lithium battery is first placed in the placement groove of the placement box 4, and the positive electrode of the lithium battery is facing upward, and then the cap is placed on the positive electrode, so that the annular covering member of the cap is located on the positive electrode and the pole in the cap is facing upward, and then the first bidirectional screw 55 is rotated to move the sliding frame 52 to the side close to each other, driving the sliding member 53 to move to the side close to each other, so that the lithium battery and the cap can be clamped front and back by the two sliding members 53 facing each other on the front and back sides, and the cap can be moved to the center of the positive electrode of the lithium battery by the sliding member 53. The electric push rod 2 is pushed in the center direction, so that the cap can just cover the positive electrode of the lithium battery, preventing the cap from being tilted and causing poor packaging effect of the subsequent lithium battery. Since the sliding members 53 on different sliding frames 52 are close to each other on both sides, they are made of soft materials. Therefore, when the sliding members 53 contact and clamp the lithium battery, they can be deformed appropriately to better adapt to lithium batteries of different sizes. After adjusting the position of the lithium battery, the electric push rod 2 is started, and the telescopic rod of the electric push rod 2 extends downward, driving the extrusion plate 3 to move downward. The extrusion plate 3 will drive the extrusion rod 61 and the telescopic member 63 to move downward, so that the space cam 62 drives the fixing member 66 and the first roller 64 to move downward. Since the elastic force of the second telescopic spring 65 is greater than the elastic force of the first telescopic spring 54, Therefore, when the telescopic member 63 contacts the sliding member 53, the telescopic member 63 will squeeze the sliding member 53 downward, while the telescopic member 63 is not greatly affected, and the first telescopic spring 54 is compressed. When the space cam 62 contacts the pole on the cap, the left side of the fixing member 66 surrounds the pole, and the first roller 64 contacts the annular covering member on the cap, and the extrusion plate 3 continues to move downward, and the space cam 62 will apply a downward squeezing force to the pole in the cap, and the fixing member 66 and the first roller 64 will also apply a downward squeezing force to the annular covering member in the cap, and the space cam 62 will squeeze the pole downward, and the fixing member 66 and the first roller 64 will also squeeze the annular covering member downward, so that the pole and the annular covering move downward. The first roller 64 is also blocked by the annular covering member and cannot move downward. At this time, the space cam 62, the telescopic member 63 and the first roller 64 are moved upward relative to the extrusion plate 3. The second telescopic spring 65 is compressed, and the extrusion rod 61 will squeeze the space cam 62, so that the space cam 62 rotates 180° along the thread groove, driving the fixing member 66 to drive the first roller 64 to rotate 180°, that is, the fixing member 66 and the first roller 64 will press and rotate on the annular covering member.When the first roller 64 rotates, it will rotate itself under the action of friction. In this way, the fixing member 66 and the first roller 64 will press around the annular covering member with the pole as the rotation center, so that the annular covering member can be pressed flat, thereby preventing one side from tilting when the cap is packaged. In this way, the packaging effect of the cap is better, thereby improving the quality of the lithium battery. When the lithium battery is packaged, the telescopic rod of the electric push rod 2 is controlled to retract and reset upward, driving the extrusion plate 3 to move upward and reset, which will cause the second telescopic spring 65 to gradually stretch and reset. When the second telescopic spring 65 is fully stretched and reset, the extrusion rod 61, the telescopic member 63, the space cam 62, the fixing member 66 and the first roller 64 will move upward and reset under the drive of the extrusion plate 3, and the space cam 62 will drive the fixing member 66 and the first roller 64 to rotate in the opposite direction along the threaded groove to reset, and the sliding member 53 will not After the telescopic member 63 is squeezed, it will move upward and reset under the action of the first telescopic spring 54, and the first bidirectional screw 55 will be rotated in the opposite direction, so that the sliding frame 52 drives the sliding member 53 to move to the side away from each other and reset, close the electric push rod 2, and then take out the packaged lithium battery. In summary, people can rotate the first bidirectional screw 55 to make the sliding frame 52 drive the sliding member 53 to move to the side close to each other, so as to clamp and limit the lithium battery and the cap, and can also push the cap toward the center direction of the positive electrode of the lithium battery through the sliding member 53 to prevent the cap from shifting and offsetting, and squeeze the space cam 62 through the squeezing rod 61, so that the space cam 62 drives the fixing member 66 and the first roller 64 to rotate 180° along the threaded groove, and press the cap by the first roller 64 to prevent one side of the cap from tilting, so that the packaging effect of the lithium battery is better, that is, the quality of the lithium battery can be better. Example 2

[0039] Based on Example 1, Figure 1 and Figure 8 As shown, it also includes a clamping mechanism 7, which includes a clamping frame 71, a second bidirectional screw 72 and a connecting rod 73. The front upper part of the placement box 4 is rotatably connected with three second bidirectional screws 72, the left side of the second bidirectional screw 72 is connected with a handle, the left side of the second bidirectional screw 72 is connected with a connecting rod 73, the middle second bidirectional screw 72 is connected with a connecting rod 73, and the middle second bidirectional screw 72 is connected with a connecting rod 73. The connecting rods 73 are all rotatably connected to the placement box 4, and the left and right sides of the second bidirectional screw 72 are both threadedly connected with clamping frames 71 for clamping and limiting lithium batteries on the left and right sides, and the two clamping frames 71 located on the same second bidirectional screw 72 correspond to the position of each placement slot respectively, and the clamping frames 71 are all slidably connected to the placement box 4.

[0040] Lithium batteries of different sizes are also different in size. Therefore, when lithium batteries of different sizes are placed in the placement slot, the lithium battery may not completely fill the placement slot, that is, the lithium battery still has space to move, so the lithium battery may not be placed in the middle of the placement slot, which will cause the cap to be unable to be located directly below the space cam 62, and the first roller 64 may not be able to press around the annular covering member with the pole as the center, resulting in the cap being tilted sideways during press-fitting. Therefore, after putting the lithium battery into the placement slot, people can turn the handle to drive the second bidirectional screw 72 on the left, and use the connecting rod 73 to make all the second bidirectional screws 72 rotate together, so that The two clamping frames 71 located on the same second bidirectional screw 72 move toward the side close to each other, so that the lithium battery can be pushed to the middle position of the placement slot by the clamping frames 71, and the lithium battery can also be clamped and limited to the left and right by the clamping frames 71 to prevent the lithium battery from shifting when it is squeezed later, thereby achieving a better packaging effect for the lithium battery and thus improving the quality of the lithium battery. When the lithium battery is packaged, the second bidirectional screw 72 on the left is rotated in the opposite direction by the handle, and all the second bidirectional screws 72 are rotated in the opposite direction by the connecting rod 73, so that the two clamping frames 71 located on the same second bidirectional screw 72 are moved to the side away from each other and reset.

[0041] Figure 1 , Fig. 9 and Fig.10 As shown, a reinforcement mechanism 8 is also included, and the reinforcement mechanism 8 includes a second slide rail 81, a third telescopic spring 82 and a clamping member 83. The lower part of the telescopic member 63 is evenly connected with three groups of second slide rails 81, each group of second slide rails 81 has four, and each group of second slide rails 81 is distributed with two on the left and two on the right. The two second slide rails 81 on the left side of each group are slidably connected with a clamping member 83, and the two second slide rails 81 on the right side of each group are also slidably connected with a clamping member 83. The clamping member 83 is used to limit the left and right positions of the cap and the lithium battery to prevent them from shifting during packaging, and a third telescopic spring 82 is connected between the clamping member 83 and the adjacent second slide rail 81.

[0042] When the telescopic member 63 moves downward, the second slide rail 81 and the clamping member 83 are also driven to move downward. When the clamping member 83 contacts the cap and the lithium battery, the two clamping members 83 in the same group of second slide rails 81 move away from each other, the third telescopic spring 82 is compressed, and the third telescopic spring 82 on the left side applies a rightward squeezing force to the left clamping member 83, and the third telescopic spring 82 on the right side applies a leftward squeezing force to the right clamping member 83, so that the clamping member 83 can be clamped between the cap and the lithium battery. The left and right sides of the cap and the lithium battery are further limited to prevent them from being displaced during the packaging process, which can also make the packaging effect of the lithium battery better, thereby making the quality of the lithium battery better. When the lithium battery packaging is completed, the telescopic member 63 will move upward and reset, driving the second slide rail 81 and the clamping member 83 to move upward and reset. After the clamping member 83 is away from the packaged lithium battery, the two clamping members 83 in the same group of second slide rails 81 will move and reset to the side close to each other under the action of the third telescopic spring 82.

[0043] Figure 1 , Fig.11 and Fig.12 As shown, it also includes a friction reduction mechanism 9, which includes a fixed block 91, a second roller 92 and a conveyor belt 93. The two clamping members 83 located in the same group of second slide rails 81 are connected to the side close to each other with four fixed blocks 91, and the four fixed blocks 91 are distributed in two upper sides and two lower sides. The two fixed blocks 91 located on the upper side of the same clamping member 83 are rotatably connected to the second roller 92, and the two fixed blocks 91 located on the lower side of the same clamping member 83 are also rotatably connected to the second roller 92. A conveyor belt 93 is wound between the two adjacent second rollers 92, and the conveyor belt 93 rotates under the action of friction, so as to reduce the friction between the clamping member 83 and the cap and the lithium battery when moving, thereby preventing the cap and the lithium battery from being worn.

[0044] When the clamping member 83 moves downward, it will also drive the fixing block 91 to move downward, so that the second roller 92 and the conveyor belt 93 also move downward. When the conveyor belt 93 contacts the cap and the lithium battery and moves downward, the conveyor belt 93 will rotate under the action of friction, driving the second roller 92 to rotate. In this way, the conveyor belt 93 can reduce the friction between the clamping member 83 and the cap and the lithium battery when it moves downward, thereby preventing the cap and the lithium battery from being worn, so that the packaged lithium battery will not be worn, and the quality of the lithium battery can be better. When the clamping member 83 moves upward and resets, the fixing block 91, the second roller 92 and the conveyor belt 93 will also move upward and reset, and the conveyor belt 93 will rotate in the opposite direction, causing the second roller 92 to rotate in the opposite direction accordingly.

[0045] Figure 1 , Fig.13 and Fig.14 As shown, it also includes a pop-up mechanism 10, which includes a fourth telescopic spring 101, a third roller 102, a pull rope 103, a pop-up frame 104 and a fourth roller 105. The middle side of the second bidirectional screw 72 is connected to the third roller 102, and the front lower side of the placement box 4 is evenly rotatably connected to three fourth rollers 105, and the fourth rollers 105 are respectively located below the adjacent third rollers 102. The rear side of the upper inner part of the placement box 4 is slidably connected to the pop-up frame 104 for automatically pushing the packaged lithium batteries upward, and the fourth telescopic spring 101 is connected between the rear lower side of the pop-up frame 104 and the placement box 4. The pull rope 103 is wound around the third roller 102, and the other end of the pull rope 103 is connected to the adjacent fourth roller 105 and the adjacent pop-up frame 104.

[0046] In the initial state, the ejection rack 104 is located at the inner upper part of the placement groove, and the pull rope 103 is in a relaxed state. When people put the lithium battery into the placement groove, that is, the lithium battery will be placed on the ejection rack 104, the ejection rack 104 will move slightly downward under the gravity of the lithium battery, and the fourth telescopic spring 101 will be slightly compressed. When people rotate the second bidirectional screw 72, the third roller 102 will also be driven to rotate, so that the pull rope 103 is gradually tightened, and the fourth roller 105 will rotate under the action of the pull rope 103, and the ejection rack 104 will also be gradually pulled downward under the action of the pull rope 103, and the fourth telescopic spring 101 will be compressed, driving the lithium battery to move gradually downward. When the lithium battery is packaged, the second bidirectional screw 72 will be rotated in the opposite direction, driving the third roller 102 to rotate in the opposite direction, so that the pull rope 103 is gradually released, and the ejection rack 104 will gradually move upward and reset under the action of the fourth telescopic spring 101, so that the lithium battery can be gradually pushed upward through the ejection rack 104, so that it is more convenient for people to take out the packaged lithium battery.
