DETAILED DESCRIPTION

[0023] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "top", "bottom", etc. used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] like Figure 1 -2, a battery conveyor belt of a preferred embodiment of an embodiment of the present invention comprises a base 1, a plurality of parallel connecting shafts 2 and a plurality of conveying wheels 3, wherein the connecting shafts 2 are mounted on the base 1, and the conveying wheels 3 are mounted on the connecting shafts 2. When a battery 7 is placed on the conveying wheels 3, the conveying wheels 3 will accelerate to convey the battery 7 away.

[0026] To facilitate understanding of the inventive concept of the present invention, a section of the entire battery conveyor belt is cut off, such as Figure 1As shown, the battery conveyor belt is provided with an initial end 4 and an end 5, wherein the end 5 is the front and the initial end 4 is the rear. The initial end 4 is used to place the battery 7, and the end 5 is used to output the battery 7. The connecting shaft 2 extends in the horizontal direction, and the connecting shaft 2 is arranged at intervals from the initial end 4 to the end 5. The base 1 includes a pair of brackets, one end of the connecting shaft 2 is fixed to one of the brackets, and the other end of the connecting shaft 2 is fixed to the top bracket. The connecting shaft 2 cannot rotate relative to the bracket. Figure 1 As shown in Figure 4, the conveying wheel 3 includes a stator 31, a rotor 32, a coil 33, a pusher 34, a receiver 35, a control circuit 36 ​​and a hub 37. An annular fixing ring 38 is provided on the connecting shaft 2. The fixing ring 38 is sleeved outside the connecting shaft 2 and fixed to the connecting shaft 2 by screws. The stator 31 is annular and sleeved outside the connecting shaft 2. The stator 31 is located on one side of the fixing ring 38. The stator 31 is fixed to the fixing ring 38 by screws.

[0027] like Figure 1 As shown in FIG. 4 , the coil 33 is sleeved outside the stator 31, and the coil 33 is fixed relative to the stator 31. The rotor 32 is sleeved outside the coil 33, and a gap is left between the rotor 32 and the coil 33. When the coil 33 is energized, the rotor 32 can rotate around the stator 31 under the action of the coil 33. The hub 37 is sleeved outside the rotor 32, and a first bearing 323 is connected between the hub 37 and the rotor 32. The pusher 34 is connected to the hub 37 and the rotor 32 respectively. When the rotor 32 rotates, the rotor 32 drives the hub 37 to rotate through the pusher 34. The receiver 35 is located on the rotor 32, and the control circuit 36 ​​is electrically connected to the coil 33 and the receiver 35 respectively. When the battery 7 is placed on the hub 37, the pusher 34 applies pressure to the receiver 35. The battery conveyor belt also includes a uniform speed wheel 8, which is divided into at least two acceleration zones and at least two uniform speed zones. The acceleration zones and the uniform speed zones are alternately distributed along the transmission direction of the battery conveyor belt. Conveying wheels 3 are arranged on all rotating shafts in the acceleration zone, and uniform speed wheels 8 are arranged on all rotating shafts in the uniform speed zone. During normal operation, the rotation speed of the wheel surface of the uniform speed wheel 8 remains unchanged, wherein the length of the acceleration zone in the transmission direction of the battery conveyor belt is greater than the maximum length of the battery 7, and the length of the uniform speed zone in the transmission direction of the battery conveyor belt is greater than the maximum length of the battery 7. Through such a design, when multiple batteries 7 are placed in sequence on the battery conveyor, the battery 7 will be spaced apart from the battery 7 behind after passing through the acceleration zone, and after the battery 7 continuously and alternately passes through the acceleration zone and the uniform speed zone, the distance between each battery 7 and the battery 7 behind will become larger and larger, thereby realizing the interval sorting of multiple batteries 7.

[0028] The working process of the present invention is as follows: when the battery 7 passes the initial end 4, the battery 7 is transported toward the terminal 5 at a uniform speed under the action of the uniform wheel 8. When the battery 7 is against the upper surface of the conveying wheel 3, the battery 7 applies pressure to the wheel hub 37, the pusher 34 is affected and contacts the receiver 35, the pusher 34 and the receiver 35 send an electrical signal to the control circuit 36, the control circuit 36 ​​changes the current passing through the coil 33, the rotor 32 rotates faster, the rotor 32 pushes the wheel hub 37 through the pusher 34, the wheel hub 37 rotates faster, and the conveying wheel 3 accelerates to transport the battery 7, while the battery 7 still on the uniform wheel 8 at the back gradually pulls away from the battery 7 on the conveying wheel 3. Among them, the speed of each conveying wheel 3 has an upper limit, and it will not accelerate continuously due to the pressure of the battery 7. In this embodiment, the acceleration of the conveying wheel 3 closer to the terminal 5 will be greater, even if multiple batteries 7 are accelerated by the conveying wheel 3, the battery 7 at the front and the battery 7 at the back can be pulled away. Among them, in this embodiment, the receiver 35 is a sensor or an action switch, which uses the sensor or action switch to receive external pressure, so that the receiver 35 sends an electrical signal to the control circuit 36. The circuit structure in which the control circuit 36 ​​receives the electrical signal transmitted by the sensor and then changes the current of the coil 33 belongs to the prior art, and the present invention does not improve the circuit structure.

[0029] In summary, an embodiment of the present invention provides a battery conveyor belt, which has a receiver 35 disposed on the rotor 32. When the conveying wheel 3 is subjected to the pressure of the battery 7, the rotor 32 can accelerate the rotation of the hub 37, so that the battery 7 on the conveying wheel 3 is accelerated to throw away the battery 7 behind, thereby forming a gap between two rows of several batteries 7 on the battery conveyor belt, and completing the interval sorting of multiple batteries 7.

[0030] like Figure 1As shown in Figure 6, in this embodiment, the battery conveyor belt also includes an elastic member 6, and the elastic member 6 and the receiver 35 are both located in the opposite direction of the rotation direction of the pusher 34. The elastic member 6 is two springs, one end of the elastic member 6 is connected to the pusher 34, and the other end of the elastic member 6 is connected to the rotor 32. The receiver 35 is located between the two springs. The receiver 35 is an action switch, and the receiver 35 is located within the moving range of the pusher 34. When there is no battery 7 on the conveying wheel 3 and the rotor 32 rotates at a constant speed, the rotor 32 uses the two springs to push the pusher 34, and the pusher 34 drives the wheel hub 37 to rotate. At this time, the action switch does not contact the pusher 34. When the battery 7 is placed on the conveying wheel 3, the battery 7 applies pressure to the hub 37, and the hub 37 applies pressure to the first bearing 323, and the internal friction of the first bearing 323 increases. At this time, the rotor 32 still keeps rotating forward, and the hub 37 is unable to keep up with the rotor 32 due to the friction. The rotor 32 and the profile rotate relative to each other until the pusher 34 abuts against the receiver 35. The receiver 35 fixed on the rotor 32 pushes the hub 37 to rotate. The receiver 35 is closed, and the control circuit 36 ​​receives the electrical signal and changes the current of the coil 33, so that the rotor 32 rotates faster. The rotor 32 pushes the pusher 34 through the receiver 35, and the pusher 34 pushes the hub 37 to rotate faster.

[0031] In other embodiments, the receiver 35 is a pressure sensor, and the pressure sensor is located below the pusher 34. When the battery 7 is placed on the conveying wheel 3, the hub 37 applies pressure to the pusher 34, and the pusher 34 applies pressure to the pressure sensor. The pressure sensor sends an electrical signal to the control circuit 36. The control circuit 36 ​​changes the current of the coil 33, so that the rotor 32 accelerates its rotation. The rotor 32 pushes the pusher 34 through the receiver 35, and the pusher 34 pushes the hub 37 to accelerate its rotation.

[0032] like Figure 3As shown in Figure 6, a groove 321 is provided on the rotor 32, and the receiver 35 and the elastic member 6 are located in the groove 321. One end of the pusher 34 is fixed to the hub 37, and the other end of the pusher 34 extends into the groove 321. The groove 321 can accommodate the receiver 35 and the elastic member 6 and protect the receiver 35 and the elastic member 6. In other embodiments, the receiver 35 and the elastic member 6 can be directly arranged on the outer surface of the rotor 32, and the pusher 34 is still fixed on the hub 37. A slide rail 331 is provided on the coil 33, and the slide rail 331 forms a circle around the outer periphery of the coil 33 along the rotation direction of the rotor 32. A slip ring 322 is fixed on the rotor 32, and the slip ring 322 can slidably abut against the slide rail 331. The receiver 35 is electrically connected to the slip ring 322, and the slip ring 322 is electrically connected to the slide rail 331. The control circuit 36 ​​is electrically connected to the slide rail 331. The control circuit 36 ​​includes an annular circuit board fixed on one side of the stator 31. The circuit board is electrically connected to the slide rail 331 through a wire, and the slip ring 322 is electrically connected to the receiver 35 through the receiver 35 wire, so that when the rotor 32 rotates, the circuit board can remain electrically connected to the receiver 35 and can transmit electrical signals.

[0033] like Figure 3 As shown in Figure 4, a cavity 21 is provided in the connecting shaft 2, and a power supply line is provided in the cavity 21. A plurality of through holes 22 are opened on the connecting shaft 2, and the through holes 22 correspond to the conveying wheels 3 one by one. The through holes 22 are communicated with the cavity 21, and the through holes 22 are located directly below the conveying wheel 3. The power supply line passes through the through holes 22 and is electrically connected to the control circuit 36. Hiding the power supply line in the cavity 21 can reduce the space occupied by the power supply line, and the setting position of the through holes 22 can prevent the power supply line from being exposed from the conveying wheel 3, thereby ensuring the safety of the power supply line.

[0034] like Figure 1 As shown in Figure 5, the stator 31 is provided with an annular mounting groove, and the coil 33 is located in the mounting groove. A first bearing 323 is connected between the stator 31 and the rotor 32, and a second bearing 311 is connected between the hub 37 and the rotor 32. The coil 33 is installed in the mounting groove, and the mounting groove can be used to protect the coil 33. A circular baffle 39 is provided on the side of the circuit board facing away from the stator 31. The baffle 39 is fixed to the stator 31 by bolts. The baffle 39 can protect the circuit board and prevent the circuit board from detaching. A rubber sleeve 371 is provided on the hub 37, and the rubber sleeve 371 is sleeved outside the hub 37. When the battery 7 is placed on the conveying wheel 3, the rubber sleeve 371 can increase the friction between the conveying wheel 3 and the battery 7 to prevent the hub 37 from rotating too fast and slipping with the battery 7.

[0035] like Figure 1 As shown in Figure 2, a pair of side baffles 11 are provided on the base 1. The side baffles 11 are located above the conveying wheel 3. A conveying space 12 is left between the two side baffles 11. The side baffles 11 are used to prevent the battery 7 from falling from the side of the battery conveyor belt during the process of the conveying wheel 3 transmitting the battery 7, ensuring that the battery 7 can only be transmitted in the conveying space 12. The plate surfaces of the two side baffles 11 are arranged to be inclined to each other. The conveying space 12 is trapezoidal. The narrowest position of the conveying space 12 allows only one battery 7 to pass through, ensuring that the battery 7 will not come out side by side from the end 5 of the battery conveyor belt. A plurality of side pulleys 13 are provided on the side baffles 11. The wheel surface of the side pulley 13 is exposed in the conveying space 12. In addition to preventing the battery 7 from falling from the side of the battery conveyor belt, the side pulley 13 can also protect the battery 7 and prevent the battery 7 from scratching the side.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
