DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] like Figure 1-Figure 5 As shown, a lithium battery flipping mechanism proposed in one embodiment of the present application includes:

[0028] A workbench 1 is provided with a rotating rod 2 rotatably mounted thereon, a columnar block 3 is mounted on the rotating rod 2, a receiving groove 4 for receiving lithium batteries is provided on the peripheral side of the columnar block 3, the receiving groove 4 extends toward the middle of the columnar block 3, and there are a plurality of receiving grooves 4 in a circular array along the axis of the columnar block 3. It should be specifically stated that the number of receiving grooves 4 is four, and when a lithium battery enters one of the receiving grooves 4, the rotating rod 2 can drive the lithium battery to turn upward by 90 degrees. At this time, the lithium battery is not easy to move due to the resistance of the groove wall of the receiving groove 4, and the other receiving groove 4 can also continue to receive the lithium battery, and the lithium battery inside it is gradually turned over as the rotating rod 2 rotates;

[0029] Two belt-wheel conveying assemblies 5, the belt-wheel conveying assemblies 5 are prior art, and include a rotating roller connected in a transmission manner and a belt sleeved on the rotating roller, both of which are installed on the workbench 1, and the two belt-wheel conveying assemblies 5 are connected in a transmission manner so that their conveying directions are consistent, and are arranged on both sides of the columnar block 3, and the lithium battery is transported by the belt-wheel conveying assemblies 5. When the columnar block 3 rotates, when the receiving groove 4 and the belt of the belt-wheel conveying assembly 5 are in a parallel state, the groove wall of the receiving groove 4 located at the lower part is coplanar with the top of the belt of the belt-wheel conveying assembly 5, so that the lithium battery can enter the receiving groove 4 under the transportation of the belt-wheel conveying assembly 5;

[0030] The pushing mechanism is arranged on the workbench 1 and is used to push the lithium battery out of the receiving slot 4. After the rotating rod 2 rotates 180 degrees, the lithium battery in the receiving slot 4 can be turned over. Then, the pushing mechanism can push the turned lithium battery out of the receiving slot 4 so that it can be moved to the belt wheel conveying assembly 5 on the other side of the columnar block 3.

[0031] The driving member 6 is a motor, which is installed on the workbench 1 and is connected to the rotating rod 2 through an intermittent motion mechanism. The intermittent motion mechanism is designed so that the rotating rod 2 is prohibited for a period of time after rotating ninety degrees, so that the lithium battery can enter the receiving slot 4;

[0032] The present application adopts the design of a columnar block 3. When the lithium battery enters one of the receiving grooves 4 on the side of the columnar block 3 under the transportation of the pulley conveyor assembly 5, the driving member 6 can drive the rotating rod 2 to rotate intermittently through the intermittent motion mechanism, so that the lithium battery on the pulley conveyor assembly 5 can enter the remaining receiving grooves 4 in turn. After the rotating rod 2 rotates one hundred and eighty degrees, the lithium battery located inside the receiving groove 4 is flipped, and then the pushing mechanism can push the flipped lithium battery out of the receiving groove 4, so that it can be moved to the pulley conveyor assembly 5 on the other side of the columnar block 3. Compared with the prior art, the device has a smaller movement amplitude when flipping the flipped lithium battery, and the flipping speed of the lithium battery is faster, thereby improving the production efficiency of the lithium battery.

[0033] like Figure 3 As shown, in some embodiments, the notches of the receiving slots 4 are each configured with a guide surface 7 , and the guide surface 7 is used to guide the movement of the lithium battery so as to facilitate the lithium battery to enter the receiving slots 4 .

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, arc plates 8 are connected to both sides of the workbench 1, the columnar block 3 is located between the two arc plates 8, and the arc diameter of the arc plate 8 is larger than the outer diameter of the columnar block 3. When the receiving groove 4 is flipped to be perpendicular to the table surface of the workbench 1, the lithium battery inside it is not easy to move toward the two sides of the receiving groove 4 due to the restriction of the arc plates 8.

[0035] like Figure 1-Figure 3 As shown, in some embodiments, an annular groove 9 is opened in the middle of the columnar block 3, the annular groove 9 is located on the outer peripheral side of the columnar block 3, and the distance between the inner annular surface of the annular groove 9 and the axis of the rotating rod 2 is smaller than the distance between the end of the accommodating groove 4 and the axis of the rotating rod 2. The design of the annular groove 9 can reduce the overall volume of the columnar block 3, thereby reducing the production cost of the device.

[0036] like Figure 2As shown, in some embodiments, the pushing mechanism includes a mounting plate 10 mounted on the workbench 1, the mounting plate 10 is close to the bottom of one of the pulley conveying components 5, and a sliding plate 11 is slidably matched at its bottom, the sliding direction of the sliding plate 11 is consistent with the conveying direction of the pulley conveying component 5, the end of the sliding plate 11 is vertically connected to a push plate 12, the push plate 12 is connected to the top of the sliding plate 11, the end of the push plate 12 is inserted into the annular groove 9, the push plate 12 is close to the inner side of the annular groove 9, and it does not contact the columnar block 3, the lithium battery is non-contacting with the end of the push plate 12 during rotation, an electric push rod 13 is installed on the mounting plate 10, and the movable end of the electric push rod 13 is connected to the sliding plate 11, after the lithium battery completes the flipping, the electric push rod 13 drives the sliding plate 11 to slide, so that the lithium battery can be pushed through the push plate 12 to make it detach from the receiving groove 4 and fall on another pulley conveying component 5.

[0037] like Figure 2 As shown, in some embodiments, a pad 14 is installed on the contact surface between the push plate 12 and the lithium battery. The pad 14 has toughness, and the arc plate 8 is a rubber block. Such a design can reduce the impact force generated when the push plate 12 contacts the lithium battery, thereby protecting the lithium battery from damage.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the intermittent motion mechanism includes a circular plate 15 installed on the output end of the driving member 6. When the driving member 6 is working, the circular plate 15 can be driven to rotate. A cylindrical block 16 is constructed in the middle of the circular plate 15. A cylindrical pin 17 is arranged on one side of the cylindrical block 16. An arc groove 18 is opened on the circumference of the cylindrical block 16, and the arc groove 18 is close to the cylindrical pin 17. A cam 19 is installed on the end of the rotating rod 2. A plurality of slots 20 and arc grooves 21 are opened on the circumference of the cam 19 in an interval and staggered manner. The arc diameter of the arc groove 18 is equal to the arc diameter of the arc groove 21, and the two are used to accommodate the cylindrical pin 17 and the cylindrical block 16 respectively, and the cylindrical pin 17 is tangent to the inner wall of the slot 20 when the circular plate 15 rotates. The arc groove 21 rotates, and the arc groove 21 cannot rotate due to the restriction of the cylindrical block 16. When the arc groove 18 of the cylindrical block 16 rotates to the direction of the arc groove 21, the cylindrical pin 17 can enter the notch of the slot 20 and conflict with the inner wall of the slot 20. At this time, the cylindrical pin 17 can move inside the slot 20 and drive the cam 19 to rotate. When the cylindrical pin 17 continues to rotate and disengages from the slot 20, the cylindrical block 16 can be accommodated by the arc groove 21, and the cam 19 stops rotating until the cylindrical pin 17 enters the next slot 20. It should be specifically noted that the number of arc grooves 21 and the slot 20 is the same as the number of accommodating slots 4, which are all four. The cam 19 can stop for a period of time after rotating ninety degrees.

[0039] like Figure 4 and Figure 5 As shown, in some embodiments, a sleeve 22 is rotatably mounted on the cylindrical pin 17, and the sleeve 22 is slidably tangent to the inner wall of the slot 20, so that the sliding friction resistance generated by the movement of the cylindrical pin 17 in the slot 20 can be converted into a rolling friction resistance between the sleeve 22 and the inner wall of the slot 20, thereby reducing the resistance encountered by the cylindrical pin 17 when moving, making it easier for the cylindrical pin 17 to move in the slot 20.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
