Description

Technical Field

[0001] The present invention relates to the technical field of cylindrical lithium battery processing, and more specifically, to an automatic unloading device for cylindrical lithium batteries. Background Art

[0002] According to the filling material, cylindrical lithium batteries can be divided into lithium iron phosphate batteries, lithium cobalt oxide batteries, lithium manganese oxide batteries and cobalt manganese mixed batteries. According to the shell type, there are steel shell lithium batteries and polymer shell lithium batteries. Common cylindrical lithium-ion batteries are composed of shells, caps, positive electrodes, negative electrodes, diaphragms and electrolytes. Generally, the battery shell is the negative electrode of the battery, the cap is the positive electrode of the battery, and the battery shell is made of nickel-plated steel. Cylindrical lithium batteries are widely used in mobile phone power supplies, digital cameras, MP3s, laptops, car starters, power tools and other portable electronic products.

[0003] There are two common ways to unload cylindrical lithium batteries in an orderly manner during the processing of cylindrical lithium batteries. One is to use a manipulator to place the cylindrical lithium batteries in a tray for transfer and unloading, which has a low unloading efficiency. The other is to push one or more cylindrical lithium batteries into a designated basket for transfer and unloading. Since lithium batteries are cylindrical and easy to roll, and multiple cylindrical lithium batteries can move with each other, they are easy to collide and rub with each other when pushed in, and they are also easy to shake after entering the basket. The stability is extremely poor, and it is easy for cylindrical lithium batteries to tip over, fall, and wear.

DETAILED DESCRIPTION

[0040] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Embodiment: A cylindrical lithium battery automatic unloading device, such as Figure 1-7 As shown, it includes a support platform 1, a roller conveyor 3, a sleeve frame 9, a pushing mechanism 5, a baffle 7, a driving mechanism 8, an inclined conveyor 10, a storage frame 11 and a material unloading frame 6. The roller conveyor 3 is arranged on the support platform 1 and is used to horizontally convey the cylindrical lithium battery 4. The roller conveyor 3 is a prior art, and its specific structure and working principle are not repeated here. A support leg 2 is arranged at the bottom of the support platform 1, and the support platform 1 is supported on the base plane by the support leg 2. The sleeve frame 9 is located on one side of the roller conveyor 3 and is placed on the support platform 1. The sleeve frame 9 is composed of a plurality of sleeve units 91 connected side by side, and the sleeve units 91 correspond one by one to the cylindrical lithium batteries 4 used for unloading on the roller conveyor 3.

[0042] Preferably, the sleeve frame 9 includes a sleeve unit 91 and a fixing plate 92. The sleeve unit 91 is used to fix the cylindrical lithium battery 4. A plurality of sleeve units 91 are arranged at equal intervals along the conveying direction of the roller conveyor 3, and the fixing plate 92 is fixed between adjacent sleeve units 91. The sleeve unit 91 includes a first sleeve ring 911, a second sleeve ring 912 and a connecting plate 913. The fixing plate 92 is fixed on the first sleeve ring 911 and the second sleeve ring 912 between adjacent sleeve units 91. The first sleeve ring 911 and the second sleeve ring 912 are both used to be sleeved on the circumferential surface of the cylindrical lithium battery 4. The connecting plate 913 is provided with a plurality of sleeve rings and is respectively connected between the first sleeve ring 911 and the second sleeve ring 912. The inner and outer diameters of the first sleeve ring 911 and the second sleeve ring 912 are the same. The inner diameters of the first sleeve ring 911 and the second sleeve ring 912 are slightly larger than the diameter of the cylindrical lithium battery 4, and the distance between the first sleeve ring 911 and the second sleeve ring 912 is less than the height of the cylindrical lithium battery 4. The first sleeve ring 911 and the second sleeve ring 912 are provided with a plurality of tightening protrusions 914 at equal intervals on the inner arc surface. The tightening protrusions 914 are used to tighten between the cylindrical lithium battery 4 and the first sleeve ring 911 or between the cylindrical lithium battery 4 and the second sleeve ring 912, so that after the cylindrical lithium battery 4 is inserted into the sleeve unit 91, the cylindrical lithium battery 4 can be tightened inside the first sleeve ring 911 and the second sleeve ring 912. The tightening protrusions 914 can be hemispherical rubber protrusions to prevent the surface of the cylindrical lithium battery 4 from being scratched, and can also be spring pieces or other forms.

[0043] In the above technical solution, the sleeve rack 9 can fix multiple cylindrical lithium batteries 4 in rows, so that the independently dispersed cylindrical lithium batteries 4 are locked in the sleeve unit 91 on the sleeve rack 9, and the cylindrical lithium batteries 4 fixed in the same sleeve rack 9 are a group. After the cylindrical lithium batteries 4 are fixed in the sleeve rack 9, the unloading and subsequent operations can be performed according to each group of cylindrical lithium batteries 4, which greatly improves the work efficiency, and can prevent the cylindrical lithium batteries 4 from shaking, falling, tilting, etc., facilitates orderly production, reduces damage to the cylindrical lithium batteries 4, and makes unloading more convenient and orderly.

[0044] Preferably, a groove 16 for accommodating the sleeve rack 9 is provided on the support platform 1. An arc groove 17 adapted to the outer arc surface of the first sleeve ring 911 and the second sleeve ring 912 is provided at the bottom of the groove 16. The arc groove 17 is used for positioning so that the cylindrical lithium battery 4 corresponds to the sleeve unit 91 one by one, which is convenient for the insertion of the cylindrical lithium battery 4. A plurality of arc grooves 17 are arranged at equal intervals along the length direction of the sleeve rack 9. The arc grooves 17 correspond to the positions of the sleeve units 91 one by one, so that each sleeve unit 91 falls into the arc groove 17. Limiting plates 15 are provided at both ends of the groove 16. The limiting plates 15 are located at both ends of the sleeve rack 9 and are used to limit the sleeve rack 9 from moving out of the two ends of the groove 16. The groove 16 passes through the outer side of the support platform 1 away from the roller conveyor 3, so that the sleeve rack 9 can be pushed out of the groove 16.

[0045] Reference Figure 1-7 , the baffle 7 is located on the other side of the sleeve frame 9 relative to the roller conveyor 3 and is used to prevent the sleeve frame 9 from moving when the cylindrical lithium battery 4 is inserted into the sleeve frame 9. The pushing mechanism 5 is located on the other side of the roller conveyor 3 relative to the sleeve frame 9. The pushing mechanism 5 is used to push the cylindrical lithium battery 4 used for unloading on the roller conveyor 3 into the sleeve unit 91. The inclined conveyor 10 is close to one side of the support platform 1 and is used to convey the storage frame 11 obliquely downward. The storage frame 11 is a square or rectangular basket with an opening at the top. When the storage frame 11 is conveyed by the inclined conveyor 10, the opening of the storage frame 11 faces the support platform 1. The inclined conveyor 10 can be a slope belt conveyor, a chain conveyor or other, and the specific type is not limited. The driving mechanism 8 is arranged on the support platform 1 and is used to drive the baffle 7 to rotate, so that the baffle 7 is obliquely overlapped between the support platform 1 and the storage frame 11, so that the cylindrical lithium battery 4 inserted into the sleeve unit 91 can slide into the storage frame 11 along the baffle 7. The cylindrical lithium batteries 4 entering the storage frame 11 will be placed in the storage frame 11 in rows along the oblique downward conveying direction of the storage frame 11, realizing orderly unloading. After the cylindrical lithium batteries 4 are fixed by the sleeve frame 9, the unloading is more stable and not easy to loosen. It is also more convenient and quick to perform secondary transfer after entering the storage frame 11.

[0046] Preferably, the driving mechanism 8 includes a motor 81, a rotating shaft 82, a first connecting rod 83, a fixing block 84, a second connecting rod 85 and a fixing seat 86. The motor 81, the fixing block 84 and the fixing seat 86 are all fixed on the supporting platform 1. One end of the rotating shaft 82 is connected to the output shaft of the motor 81, and the other end passes through the fixing block 84 and is inserted into the fixing seat 86. The axial direction of the rotating shaft 82 is consistent with the conveying direction of the roller conveyor 3. One end of the first connecting rod 83 is fixed to the rotating shaft 82, and the other end is rotatably connected to the second connecting rod 85. One end of the second connecting rod 85 is rotatably connected to the first connecting rod 83, and the other end is rotatably connected to the side of the baffle 7 away from the sleeve frame 9. Specifically, a mounting plate is fixed to the side of the baffle 7 away from the sleeve frame 9, and the mounting plates are located on opposite sides of the baffle 7. The second connecting rod 85 is rotatably connected to the mounting plate. The baffle plate 7 contacts the outer side of the blanking frame 6, and the lower side of the baffle plate 7 is rotatably connected to the support platform 1. The height position of the rotating shaft 82 is lower than the height position of the rotatably connected part of the baffle plate 7 and the support platform 1, so that when the rotating shaft 82 drives the baffle plate 7 to rotate, the baffle plate 7 can tilt downward toward the storage frame 11, so that the sleeve rack 9 can smoothly fall into the storage frame 11 along the baffle plate 7.

[0047] Preferably, side plates 14 are fixed on opposite sides of the baffle 7, and the two side plates 14 are respectively located outside the two ends of the sleeve frame 9 and respectively contact the outer surfaces of the opposite sides of the blanking frame 6. The provision of the side plates 14 can, on the one hand, prevent the sleeve frame 9 from moving toward the two ends when in the groove 16, and on the other hand, prevent the sleeve frame 9 from sliding off the two sides of the baffle 7 when the baffle 7 is tilted.

[0048] In order to allow the sleeve rack 9 with the cylindrical lithium battery 4 inserted to fall smoothly into the storage frame 11 along the inclined direction of the baffle 7 and to enable the sleeve unit 91 to correspond one-to-one with the arc groove 17, preferably, a roller 915 is provided on the outer surface of the first ring 911 and the second ring 912, and the roller 915 is used to contact the bottom of the arc groove 17 on the support platform 1.

[0049] Reference Figure 1-7 A connecting column 13 is fixed on the support platform 1, and a top plate 12 is fixed on the top of the connecting column 13. The top plate 12 is located above the roller conveyor 3. The bottom surface of the top plate 12 is close to the top surface of the cylindrical lithium battery 4 on the roller conveyor 3, so that the cylindrical lithium battery 4 on the roller conveyor 3 is pushed away by the pushing mechanism 5 along the width direction of the roller conveyor 3. The unloading frame 6 is opened at the top and bottom. The unloading frame 6 is located on one side of the roller conveyor 3 and fixed on the support platform 1. Specifically, a connecting column 13 is fixed on the top plate 12, and the unloading frame 6 is fixed to the top plate 12 through the connecting column 13, so that the unloading frame 6 is suspended above the groove 16. A plurality of sleeve racks 9 are stacked up and down in the unloading frame 6, and a gap is left between the bottom surface of the unloading frame 6 and the support platform 1 for the sleeve rack 9 to pass through, and the gap width is slightly larger than the outer diameter of the first ring 911 and the second ring 912.

[0050] Preferably, the pushing mechanism 5 includes a push plate 51, a cylinder 52 and a base 53. The cylinder 52 is fixed on the supporting platform 1 through the base 53, and the cylinder 52 is used to drive the push plate 51 to move horizontally back and forth along the width direction of the roller conveyor 3. The push plate 51 is located on the other side of the roller conveyor 3 relative to the sleeve frame 9. The push plate 51 is used to push the cylindrical lithium battery 4 for unloading on the roller conveyor 3 into the sleeve frame 9 and to push the sleeve frame 9 equipped with the cylindrical lithium battery 4 onto the baffle 7 after being inclined.

[0051] In the present invention, when unloading, the sleeve racks 9 are placed one by one into the unloading frame 6 with the roller 915 facing downward, so that the unloading frame 6 is filled with sleeve racks 9 from top to bottom. At this time, the lowest sleeve rack 9 will fall into the gap between the unloading frame 6 and the support platform 1. With the cooperation of the groove 16, the arc groove 17, the roller 915 and the limit plate 15, the lowest sleeve rack 9 is precisely positioned so that the central axis of the first ring 911 and the second ring 912 coincides with the central axis of the cylindrical lithium battery 4 to be inserted. When the rollers of the roller conveyor 3 are full of cylindrical lithium batteries 4 and reach the specified position, the roller conveyor 3 stops and the cylinder 52 starts. At this time, the push plate 51 will push the cylindrical lithium batteries 4 to be unloaded on the roller into the first ring 911 and the second ring 912. After the cylindrical lithium batteries 4 are inserted into the first ring 911 and the second ring 912, the cylinder 52 stops and the motor 81 starts. With the cooperation of the first connecting rod 83 and the second connecting rod 85, the baffle 7 will gradually rotate from a vertical state to a direction close to the storage frame 11 until the baffle 7 is tilted downward and the lower end is close to or located at the opening of the storage frame 11. After the baffle 7 is overlapped between the support platform 1 and the storage frame 11, the motor 81 stops and the cylinder 52 starts, so that the push plate 51 continues to push forward, thereby pushing the sleeve rack 9 with the cylindrical lithium battery 4 inserted onto the baffle 7. At this time, the sleeve rack 9 with the cylindrical lithium battery 4 inserted will automatically fall into the storage frame 11 along the baffle 7, and then the push plate 51 is gradually withdrawn, the baffle 7 will also gradually return to its original position, and the storage frame 11 will also be transported downward for a certain distance to allow the sleeve rack 9 with the cylindrical lithium battery 4 to continue to fall in. After the push plate 51 is withdrawn from the bottom of the unloading frame 6, the sleeve rack 9 at the bottom of the unloading frame 6 will automatically fall into the groove 16, so that other cylindrical lithium batteries 4 can continue to be unloaded.

[0052] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
