DETAILED DESCRIPTION

[0040] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] See also Figure 1-3A method for using an automatic flipping mechanism for a PACK battery comprises a frame 1, wherein the frame 1 is provided with a pair of left and right rotating wheels 2, an upper fixing plate 3 and a lower fixing plate 10 are fixed between the pair of rotating wheels 2, a guide member 4 is provided in the pair of rotating wheels 2, an upper clamping plate 5 and a lower clamping plate 6 are connected to the guide member 4, a plurality of product limiting columns 7 for fixing the PACK battery are fixed on the front and rear sides of the lower end of the upper clamping plate 5 and the front and rear sides of the upper end of the lower clamping plate 6, the upper clamping plate 5 and the lower clamping plate 6 are arranged between the upper fixing plate 3 and the lower fixing plate 10, and the upper clamping plate 5 and the lower clamping plate 6 are driven by a first driving device 8 to move toward each other; the pair of rotating wheels 2 are driven to rotate by a second driving device;

[0042] Step 1: manually or mechanically deliver the packed battery into the working area between the upper clamping plate 5 and the lower clamping plate 6;

[0043] Step 2: The upper clamping plate 5 and the lower clamping plate 6 are guided by the guide members on both sides and driven by the first driving device to open the upper clamping plate 5 and the lower clamping plate 6 to the maximum, and the Pack battery is placed in the working area;

[0044] Step 3: After the product is in place, the first drive device drives the upper clamping plate 5 and the lower clamping plate 6 to squeeze the battery pack towards each other, and the product limiting columns 7 limit the forward and backward displacement of the product, and the second drive device rotates the wheel to flip the product 180°;

[0045] Step 4: Automatically flip into place, the first driving device drives the upper clamping plate 5 and the lower clamping plate 6 to open to the maximum, at this time the Pack battery is removed, and the process is completed.

[0046] The product limiting column 7 is used to limit the forward and backward displacement of the product. After the upper and lower clamps are squeezed, the pack battery is used to limit the upward and downward displacement of the product to prevent the pack battery from shaking and moving during rotation.

[0047] See also Figure 4 In one embodiment of the present invention, the guide member 4 includes a transverse fixing plate 41 fixed to the middle of the rotating wheel 2, an upper guide rod 42 and a lower guide rod 43. The lower end of the upper guide rod 42 is fixed to the transverse fixing plate 41, and the other end is fixed to the rotating wheel 2. The upper guide rod 42 has an upper sliding sleeve 44, and the upper sliding sleeve 44 is fixedly connected to the upper clamping plate 5.

[0048] The upper end of the lower guide rod 43 is fixed on the horizontal fixing plate 41, and the other end is fixed on the rotating wheel 2. The lower guide rod 43 has a lower sliding sleeve 45, and the lower sliding sleeve 45 is fixedly connected to the lower splint 6; the guide member 4 of the present invention can assist the upper splint and the lower splint to perform opening and closing movements.

[0049] In addition, a position slot-type photoelectric device is provided beside the upper guide rod 42 and the lower guide rod 43 to detect whether the opening and closing strokes of the upper and lower splints have reached the preset value;

[0050] The in-place slot-type photoelectric device uses existing conventional technical components to detect the movement of the upper and lower clamps (using light as the sensing medium, and receiving and converting signals through infrared light between the light-emitting body and the light-receiving body, thereby achieving accurate detection of the object's position.).

[0051] In another embodiment of the present invention, a through-beam photoelectric sensor 11 is provided on the transverse fixing plate 41 .

[0052] Furthermore, pressure sensors are fixed on the upper and lower clamping plates. The pressure sensors and the through-beam photoelectric sensor 11 work together to determine whether the product is in place. When the upper and lower clamping plates are combined to compress the battery pack, the pressure sensors can perform corresponding detection. By setting the upper limit of the product pressure of the pressure sensor, excessive clamping force is prevented from damaging the product. When the pressure exceeds the preset value, the pressure sensor sends a signal to the electric screw 81 to stop working.

[0053] See also Figure 6-8 In one embodiment of the present invention, an automatic flipping in place detection mechanism is further included, which includes a cylinder 12 fixed on a side frame just below the rotating wheel, an extension and retraction proximity sensor 13 fixed to the top of the cylinder 12, a slot-shaped photoelectric 14 fixed to the top of the cylinder 12, and a latch 16 provided on the frame and cooperating with the telescopic end of the cylinder 12. Latch holes for cooperating with the latch 16 to realize rotation in place detection are provided just below and just above the rotating wheel. An induction sheet metal 15 is fixed on the rotating wheel to cooperate with the slot-shaped photoelectric 14 for detecting whether the rotating wheel has rotated into place.

[0054] Specifically, the upper and lower pin holes are divided into an upper pin hole 23 and a lower pin hole 22;

[0055] In the present invention, there are two detections for rotation into position. The first is that the cylinder 12 on the side will push out the pin 16. After the pin 16 is pushed into the pin hole, it will be retracted and the proximity sensor 13 will feedback that the sensing is complete. The second detection is the detection of the position plus forward and reverse rotation. A long and a short sensing sheet metal 15 and a fixed slot-shaped photoelectric 14 are installed at the upper and lower positions of the rotating disk for detection.

[0056] The aforementioned components such as the extending and retracting proximity sensor 13 and the slot-shaped photoelectric sensor 14 are all existing components, and their working principles are well known to those skilled in the art.

[0057] See also Figure 5In one embodiment of the present invention, it also includes an anti-fall ratchet mechanism 17, which includes a pair of ratchet fixing plates 171, a locking block 172 and a spring self-resetting cylinder 173. The upper splint or the lower splint is fixed with the pair of ratchet fixing plates 171, and the ratchet fixing plates 171 are provided with ratchets 174. The locking block 172 and the spring self-resetting cylinder 173 are fixed on the upper and lower fixing plates. The middle part of the locking block 172 has a card hole that cooperates with the spring self-resetting cylinder 173; the ratchets on a pair of ratchet fixing plates 171 face different directions, such as Figure 5 As shown in the figure, one direction is obliquely upward and the other is obliquely downward, which can protect the first drive device and the corresponding upper and lower fixing plates before and after flipping to prevent falling.

[0058] See also Figure 2 and Figure 9 In one embodiment of the present invention, rotation limit blocks 18 are fixed to the upper and lower ends of the inner side of the rotating wheel 2, and a limit block 24 for limiting the rotation limit block 18 is provided on the frame 1 beside the lower end of the rotating wheel 2 to prevent over-rotation and 180° hard limit.

[0059] See also Figure 1 and Figure 3 In one embodiment of the present invention, the first driving device 8 is an electric screw 81, which is arranged on the upper fixed plate 3 and the lower fixed plate 10. The electric screw 81 has multiple ends, and the telescopic end of the electric screw 81 on the upper fixed plate 3 is fixedly connected to the upper clamping plate 5, and the telescopic end of the electric screw 81 on the lower fixed plate 10 is fixedly connected to the lower clamping plate 6.

[0060] See also Figure 2 In one embodiment of the present invention, the second driving device 9 includes a motor 91, a large gear 92 and a small gear 93. The large gear 92 is driven to rotate by the motor 91, the large gear 92 is engaged with the small gear 93, and the small gear 93 is engaged with the rotating wheel 2 to rotate.

[0061] See also Figure 2 In one embodiment of the present invention, a passive wheel assembly is further included, and the passive wheel assembly includes an auxiliary passive gear 19 meshing with the rotating wheel 2 to provide support. An automatic oil injection pump 20 is provided next to the auxiliary passive gear 19.

[0062] See also Figure 1 In one embodiment of the present invention, a quick-install connecting plate 21 is fixed to the bottom of the rack, and a plurality of threaded holes are opened on the quick-install connecting plate 21 to provide a connection method for subsequent customized connecting components.

[0063] In summary, in a preferred embodiment of the present invention, the implementation scheme of the present invention is as follows:

[0064] Step 1: Send the packed battery into the working area between the upper and lower clamping plates manually or mechanically;

[0065] Step 2: The upper and lower clamping plates are driven by the guides on both sides and the electric screw to open to the maximum. After the positioning is sensed by the photoelectric in-position slot, the battery is automatically forked and placed on the product limit column, then descends and exits the working range.

[0066] Step 3: After the through-beam photoelectric sensor and pressure sensor determine that the product is in place, the electric screw drives the upper and lower clamps to squeeze and clamp the battery up and down. After the in-place slot photoelectric and pressure sensors make multiple judgments, the motor drives the reducer to rotate the large gear and the small gear, and the small gear drives the rotating wheel to flip 180 degrees.

[0067] Step 4: Automatic flipping into position is double-detected by the slot-type photoelectric and cylinder latch components. If the extended proximity sensor sensing and the cylinder latch components are in place, the electric screw drives the upper and lower splints to open to the maximum, and the battery pack is removed at this time.

[0068] In one embodiment of the present invention, it also includes power-off and air-off protection for the rotating mechanism: the motor adopts a brake motor to complete the power-off and air-off maintenance of the mechanism; power-off and air-off protection for the lifting mechanism: the screw lifting platform drive motor adopts a brake motor and is equipped with 2 sets of anti-fall quick tooth components. No matter it is rotated upward or downward, it can provide anti-fall protection. After the spring self-reset cylinder is cut off, the cylinder automatically extends into the card hole of the locking block and gets stuck to prevent the mechanism from falling.
