Description

Technical Field

[0001] The utility model relates to a turnover conveying line for cylindrical battery shells, belonging to the technical field of automatic shell conveying. Background Art

[0002] Cylindrical batteries are divided into lithium cobalt oxide, lithium manganese oxide, ternary materials, etc. The three material system batteries have different advantages, and the batteries are widely used in: electric vehicles, laptops, digital cameras, lighting fixtures, toy products, power tools, portable mobile energy and other fields.

[0003] After the cylindrical battery shell is produced and formed, it needs to be tested before battery assembly. Testing and assembly generally require the design of an automated production line to meet the automated transportation of the cylindrical battery shell. The cylindrical battery shell generally includes a tubular body, one end of the tubular body is a closed end, and the other end is a ring end.

[0004] After the cylindrical battery shell is formed, it is conveyed in an axially vertical state. When entering the automated testing equipment or assembly equipment, the fed cylindrical battery shell is required to be in a fixed orientation. Therefore, it is necessary to flip the cylindrical battery shell 180° during the conveying process.

[0005] In the prior art, a robotic arm is generally used to perform the corresponding shell picking and then turning, or a flipping mechanism is used to perform the flipping operation after picking up. Among them, the cost of the robotic arm is relatively high, and its stroke control is relatively difficult, and the debugging cost is also relatively high. The flipping mechanism generally adopts the operation of clamping the outer wall of the shell and then flipping. The clamping can easily cause damage to the outer wall of the shell. At the same time, it requires the conveyor line to provide clamping space. When the clamping space requirement is met, the side stop of the conveyor line will inevitably be too low, which will affect the automatic transportation of the battery shell. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] The utility model provides a cylindrical battery shell turning conveyor line, such as Figures 1 to 6 As shown, it includes a feeding conveyor line 1 and a discharging conveyor line 2. The discharging end of the feeding conveyor line 1 is provided with a column supply part 3, and the feeding end of the discharging conveyor line is provided with a column receiving part 4 arranged parallel to the column supply part. A material turning and transferring device is provided between the column supply part and the column receiving part.

[0035] The material flipping and transferring device includes a lifting and picking mechanism 5 with lifting displacement located at the top of the entire supply section, a material discharge and picking mechanism 6 with lifting displacement located at the top of the entire material receiving section, and a shell flipping and transferring mechanism 7 for switching displacement between the lifting and picking mechanism and the material discharge and picking mechanism.

[0036] The lifting and picking mechanism 5 includes a plurality of lifting and picking parts 50 facing the aligned supply part, and the unloading and picking mechanism 6 includes a plurality of unloading and picking parts 60 facing the aligned receiving part.

[0037] The shell flip transfer mechanism 7 includes a switching displacement carrier 71 and a flip carrier 72 with a flip stroke of at least 180° arranged on the switching displacement carrier. A plurality of shell positions 73 are arranged on the flip carrier 72. The shell positions 73 include an arc-shaped groove 731 that matches the outer peripheral wall of the cylindrical battery shell and at least one negative pressure adsorption end 732 arranged in the arc-shaped groove.

[0038] Specific implementation process and principle description:

[0039] First, the feeding conveyor line 1 conveys the vertically placed cylindrical battery shells to the column supply part 3. At this time, the lifting and picking part 50 of the lifting and picking mechanism 5 picks up the cylindrical batteries thereon in batches by using the end face top suction method. Then, the flip carrier 72 on the switching displacement carrier 71 is horizontally displaced toward the lifting and picking mechanism 5. The cylindrical battery shells on the lifting and picking part 50 are displaced one by one into the arc groove 731. The outer peripheral wall of the cylindrical battery shell is attached to the arc groove 731 and is sucked by the negative pressure suction end 732. After the material is adsorbed and fixed, the switching displacement carrier 71 is translated and separated from the lifting and picking mechanism 5. After separation, the flip carrier 72 is flipped 180° and then translated to be relative to the material discharge and picking mechanism 6. At this time, the flipped cylindrical battery shell is located at the bottom of the material discharge and picking part 60. At this time, the material discharge and picking part 60 adsorbs the end face of the cylindrical battery shell. After adsorption, the shell flip transfer mechanism 7 is reset. At this time, the material discharge and picking mechanism 6 descends, and the flipped cylindrical battery shell is placed on the entire row of material receiving parts 4, and then output by the material discharge conveyor line 2.

[0040] In a specific embodiment, Figure 6 As shown, the alignment supply part 3 includes an alignment positioning mechanism 8 for aligning and positioning the cylindrical battery shells supplied by the feeding conveyor line. The alignment positioning mechanism 8 includes a first rib 81 and a second rib 82 respectively arranged on both sides of the discharge end, and a limit stop part 83 arranged at the end of the discharge end. The first rib and the second rib have relative opening and closing displacement.

[0041] That is, the supply material is stopped by the limit stop part 83, and the position of the entire row of materials is corrected by the relative clamping of the first side guard 81 and the second side guard 82, so that its position is accurate and meets the relative position accuracy requirements of the lifting and picking part 50.

[0042] In a specific embodiment, the first rib 81 is a fixed rib, the second rib 82 has a relative linear displacement toward the first rib, and a plurality of material sensors 84 are disposed on the fixed rib.

[0043] Specifically, the number of cylindrical battery shells can be monitored through the material sensor 84. When the required number and alignment accuracy are reached, the second rib 82 is driven for relative displacement, thereby making the guidance more accurate and reliable.

[0044] In a specific embodiment, Figure 2 As shown, the lifting and picking mechanism 5 includes a lifting support carrier 51 and a lifting platform 52 with guided lifting displacement arranged on the lifting support carrier 51, and a plurality of lifting and picking parts are arranged at the bottom of the lifting platform, and the lifting and picking parts are lifting negative pressure picking ends.

[0045] Generally, the lifting and picking part is a picking mechanism used for clamping, negative pressure adsorption, magnetic adsorption and the like. When the clamping design is adopted, it is necessary to provide a space design to avoid the arc-shaped groove 731, so as to meet the material changeover coordination requirements. In the preferred embodiment, the negative pressure adsorption method is adopted. The negative pressure adsorption does not require a space avoidance design and has no requirements on materials. Of course, structures adopting clamping, magnetic adsorption and the like are also within the protection scope of this case.

[0046] In a specific embodiment, Figure 4 As shown, the material discharging and picking mechanism 6 includes a material discharging support carrier 61 and a material discharging lifting platform 62 with guided lifting displacement arranged on the material discharging support carrier 61, and a plurality of material discharging and picking parts 60 are arranged at the bottom of the material discharging and picking parts are negative pressure picking ends for discharging.

[0047] The discharge picking mechanism 6 is similar to the lifting picking mechanism 5 in structure and operation principle, and will not be described in detail here. The difference between the two is that the control and adjustment of the lifting displacement are different. The lifting picking mechanism 5 lifts and docks after picking up the material, while the discharge picking mechanism 6 places the material after docking.

[0048] In a specific embodiment, Figure 5 As shown, the shell flip transfer mechanism 7 includes a rack 9 for bridging the switching displacement carrier, and a linear displacement driving source 90 is provided on the rack 9 and is transmission-connected to the switching displacement carrier.

[0049] The rack 9 is used to carry the shell flip transfer mechanism 7 to perform linear displacement switching. It can be a single-track or double-track rack design. The rack structure belongs to the existing technology and will not be described in detail here.

[0050] In a specific embodiment, the switch displacement carrier 71 is provided with two spaced-apart pivot coupling positions 711, and the two ends of the flip carrier are respectively rotatably coupled to the pivot coupling positions. A rotation driving source 712 drivingly connected to the flip carrier is provided at any pivot coupling position.

[0051] That is, the rotational displacement drive of the flip carrier is realized by the rotation driving source 712. Generally, the rotation stroke of the flip carrier is one circle, which meets the adjustment requirement of covering a 180° stroke and does not affect its connection to the air source pipeline.

[0052] In a specific embodiment, the material turning and transferring device includes a mounting base 10 for mounting a lifting and picking mechanism, a material placing and picking mechanism, and a shell turning and transferring mechanism.

[0053] By mounting the base 10 , it is easy to realize the mounting and coordinated construction of the lifting and picking mechanism, the material placing and picking mechanism, and the shell flipping and transferring mechanism to form an integrated operating device.

[0054] In a specific embodiment, the feed conveyor line and the discharge conveyor line respectively include a conveyor line carrier and a supporting conveyor chain belt arranged on the conveyor line carrier, and shell ribs are respectively provided on both sides of the supporting conveyor chain belt.

[0055] The structure of the conveyor line carrier belongs to the existing technology, which is mainly used for conveying cylindrical battery shells in a row vertically in the axial direction. The shell ribs can limit the side position of the shells, and the shell ribs will not limit or interfere with the picking and placing strokes of the lifting and picking mechanism 5 and the material placing and picking mechanism 6 of this case, and the cooperation is smoother and more stable.

[0056] From the above description, it can be found that the utility model adopts the method of setting translation and flipping between lifting and discharging to achieve smooth flipping material transfer, thereby avoiding the sidewall of the conveyor line, so that the operation is reliable and stable. The turnover alignment is accurate, and the shell handover docking is stable and smooth, ensuring the continuity and reliability of flipping transportation. The structure is ingenious and the operation is efficient and smooth, which is suitable for construction on cylindrical battery assembly production lines.

[0057] The term "comprise" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that includes a list of elements includes not only those elements but also other elements not expressly listed, or also includes elements inherent to such process, method, article, or apparatus / device.

[0058] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
