Description

Technical Field

[0001] This utility model relates to the field of battery pack manufacturing technology, and in particular to a battery pack flipping device. Background Technology

[0002] During battery pack production, due to process requirements, after the inverted loading process, the battery pack needs to be quickly flipped 180° for subsequent processes such as upright pressurization and CCS welding. Alternatively, the battery pack may need to be flipped 180° a second time for packaging and shipping after production is complete. Therefore, a device for flipping battery packs is needed.

[0003] CN214732375U discloses a battery pack transfer device and its flipping mechanism. The flipping mechanism includes a support, an adapter, and a rotating support assembly. The rotating support assembly includes a first and a second intersecting support rod, with both ends of the first and second support rods respectively tractably mounted on the support and the adapter. The adapter is used to fixably connect to a carrier carrying the battery pack, and the adapter can rotate relative to the support under the action of the rotating support assembly and the driving component, thereby causing the carrier to flip. During the flipping process, the second and fourth hinge points connecting the first and second support rods to the adapter can both serve as fulcrums for the rotation of the adapter, and both the first and second support rods can rotate relative to the support, thus causing the height of the fulcrum of the adapter to change in real time. In this way, the middle area of ​​the carrier can continuously flip outward during rotation, while maintaining a roughly constant height, thereby facilitating manual operation of the middle area of ​​the battery pack. However, the battery pack in this patent is installed on the flipping mechanism by means of snap-fit ​​and threaded fastening. Although this installation method can prevent the battery pack from falling off during the flipping process, it takes a lot of time to install or remove, resulting in reduced production efficiency.

[0022] (3) When the first rodless cylinder drives the hook block forward to touch the outer wall of the hook opening, the hook block is squeezed and rotates downward around the hinge point to compress the spring. The compression spring has elastic force. The first rodless cylinder continues to drive the hook block forward. When the hook block reaches the hook opening, the elastic force of the compression spring drives the hook block to rotate upward around the hinge point, so that the hook block hooks the hook opening. Then the first rodless cylinder drives the hook block to move backward, so as to pull the tooling and the battery pack inside the tooling into the U-shaped seat.

[0023] This invention uses a pressure plate to press the battery pack firmly onto the first flow strip, facilitating subsequent flipping. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] like Figures 1-10 As shown, this utility model provides a first embodiment of a battery pack flipping device, including a base 1, a U-shaped seat 2 with an opening facing forward is provided above the base 1, the U-shaped seat 2 is driven to flip by a flipping component 3; a plurality of first support seats 4 are fixed on the inner bottom surface of the U-shaped seat 2, the top of the first support seat 4 has a first flow strip 5, which can play a supporting and guiding role in the process of the battery pack entering the U-shaped seat 2; two mounting plates 6 are provided above the first flow strip 5, the mounting plates 6 are driven by a lifting component 7; a pressure plate 8 for pressing the battery pack is fixed at the bottom of the mounting plate 6.

[0037] After the battery pack enters the U-shaped seat 2, the lifting component 7 drives the mounting plate 6 to move downward, thereby causing the pressure plate 8 to move downward to press the battery pack. The pressure plate 8 clamps the battery pack onto the first flow bar 5. Then, the flipping component 3 drives the U-shaped seat 2 to flip 180°, thereby realizing the flipping of the battery pack.

[0038] The inner top surface of the U-shaped seat 2 is fixed with a plurality of second support seats 9, and the bottom of the second support seat 9 has a second flow strip 10. After the flipping component 3 drives the U-shaped seat 2 to flip, the lifting component 7 retracts, causing the battery pack to move downward and fall onto the second flow strip 10. The second flow strip 10 can support the battery pack and also guide it when the battery pack is unloaded.

[0039] The lifting assembly 7 includes a hydraulic cylinder 71 fixed to the top of the U-shaped seat 2. The lower push rod of the hydraulic cylinder 71 penetrates the top of the U-shaped seat 2 and is fixedly connected to the top of the mounting plate 6. The hydraulic cylinder 71 can drive the mounting plate 6 to move up and down, thereby driving the pressure plate 8 to move up and down.

[0040] The flipping assembly 3 includes two arc-shaped seats 31 fixed to the outside of the U-shaped seat 2. A first chain 32 is fixed to the outside of the arc-shaped seat 31. A motor 33 is fixed on the base 1. A second sprocket 34 is fixed on the output shaft of the motor 33. A drive shaft 36 is connected to the base 1 behind the motor 33 via a first bearing 35. A third sprocket 37 is fixed on the drive shaft 36. The second sprocket 34 is connected to the third sprocket 37 via a second chain 38.

[0041] Both ends of the drive shaft 36 are fixed with first sprockets 39 that cooperate with the first chain 32. The drive shaft 36 is also equipped with first rollers 310 that contact the arc-shaped seat 31. The top front end of the base 1 is connected to driven shafts 312 on both the left and right sides via second bearings 311. The driven shafts 312 are equipped with second rollers 313 that contact the arc-shaped seat 31.

[0042] Motor 33 drives the second sprocket 34 to rotate, which in turn drives the second chain 38, which in turn drives the third sprocket 37 to rotate. The third sprocket 37 then drives the drive shaft 36 to rotate, which in turn drives the two first sprockets 39 to rotate. The two first sprockets 39 then drive the two first chains 32, which in turn cause the U-shaped seat 2 to rotate. During the rotation process, the first roller 310 and the second roller 313 provide support and guidance.

[0043] In this embodiment, two support columns 11 can be fixed at both the front and rear ends of the top of the base 1. When the U-shaped seat 2 is at 0°, the tops of the two support columns 11 at the front end are in contact with the bottom of the U-shaped seat 2. When the U-shaped seat 2 is at 0° and 180°, the tops of the two support columns 11 at the rear end are in contact with the bottom of the U-shaped seat 2, which is used to support the U-shaped seat 2.

[0044] Based on the first embodiment, this utility model provides a second embodiment of a battery pack flipping device. A guide shaft 72 is fixed at both the front and rear ends of the top of the mounting plate 6. The upper end of the guide shaft 72 is connected to the U-shaped seat 2 via a linear bearing 73. The guide shaft 72, in cooperation with the linear bearing 73, can provide a limiting and guiding function when the mounting plate 6 moves up and down. Proximity switches 75 are fixed to the sides of the two guide shafts 72 on the front side of the top of the U-shaped seat 2 via a first mounting bracket 74. A sensing ring 76, cooperating with the proximity switch 75, is fixed to the top of the guide shaft 72. When the guide shaft 72 rises and the proximity switch 75 senses the sensing ring 76, the hydraulic cylinder 71 stops, preventing the mounting plate 6 from hitting the inner top surface of the U-shaped seat 2.

[0045] In this embodiment, the diameter of the sensing ring 76 is larger than the outer diameter of the linear bearing 73, so that the sensing ring 76 can block the upper end of the linear bearing 73, thereby preventing the guide shaft 72 from completely disengaging from the linear bearing 73.

[0046] Based on any of the above embodiments, the present invention provides a third embodiment of a battery pack flipping device, wherein a first rodless cylinder 121 is fixed at both the left and right ends of the inner bottom surface of the U-shaped base 2, a feeding plate 122 is fixed on the slide of the first rodless cylinder 121, and a pull hook 13 is provided at both the left and right ends of the bottom of the feeding plate 122 via a first connecting plate 123.

[0047] In this embodiment, the battery pack is disposed in a fixture 14, which has a hook opening 141 for the pull hook 13 to engage. By engaging the hook opening 141 with the pull hook 13, the first rodless cylinder 121 can pull the fixture 14 and the battery pack inside the fixture 14 into the U-shaped seat 2. During the pulling process, the first flow strip 5 plays a supporting and guiding role.

[0048] The hook 13 includes a U-shaped block 131 fixed on the first connecting plate 123. A hook block 132 is provided in the opening of the U-shaped block 131. The front end of the hook block 132 is hinged to the U-shaped block 131. The rear side of the bottom surface of the hook block 132 has a telescopic groove 133. The telescopic groove 133 is connected to the U-shaped block 131 by a compression spring 134.

[0049] When the first rodless cylinder 121 moves the hook block 132 forward to touch the outer wall of the hook opening 141, the hook block 132 is compressed and flips downward around the hinge point, compressing the compression spring 134. The compression spring 134 has elastic force. The first rodless cylinder 121 continues to move the hook block 132 forward. When the hook block 132 reaches the hook opening 141, the elastic force of the compression spring 134 causes the hook block 132 to flip upward around the hinge point, so that the hook block 132 hooks the hook opening 141. Then the first rodless cylinder 121 moves the hook block 132 backward, pulling the tooling 14 and the battery pack inside the tooling 14 into the U-shaped seat 2.

[0050] The U-shaped base 2 has two ends of its inner top surface fixed with second rodless cylinders 151. A feeding plate 152 is fixed on the slide of the second rodless cylinder 151, and a pusher block 153 is fixed at the bottom of the feeding plate 152. When the U-shaped base 2 is rotated 180°, the lifting assembly 7 moves down, so that the fixture 14 and the battery pack inside the fixture 14 fall onto the second flow bar 10. Then, the second rodless cylinder 151 drives the pusher block 153 to push the fixture 14 and the battery pack inside the fixture 14 backward for feeding.

[0051] Based on the third embodiment, this utility model provides a fourth embodiment of a battery pack flipping device. The inner bottom surface of the U-shaped base 2 is located outside the first rodless cylinder 121 and is fixed with a feeding stop 125 via a third support base 124. The inner top surface of the U-shaped base 2 is located outside the second rodless cylinder 151 and is fixed with a discharging stop 155 via a fourth support base 154. The feeding stop 125 serves to limit the movement of the battery pack as the first rodless cylinder 121 pulls it into the U-shaped base 2, preventing the battery pack from falling off the sides of the U-shaped base 2. Similarly, the discharging stop 155 serves to limit the movement of the battery pack as the second rodless cylinder 151 pushes it out of the U-shaped base 2, preventing the battery pack from falling off the sides of the U-shaped base 2.

[0052] Based on any of the above embodiments, the present invention provides a fifth embodiment of a battery pack flipping device, wherein a first spinning cylinder 161, a first hydraulic buffer 162, a third flow bar 163 and a first through-beam sensor 164 are fixed on one side of the front end of the base 1, and the same components are symmetrically fixed on the other side.

[0053] The second spinning cylinder 171, the second hydraulic damper 172, the fourth flow bar 173, and the second through-beam sensor 174 are fixed on one side of the rear end of the base 1, and the second spinning cylinder 171, the second hydraulic damper 172, the fourth flow bar 173, and the second through-beam sensor 174 are symmetrically fixed on the other side.

[0054] It also includes a loading trolley 18 and a unloading trolley 19. The loading trolley 18 is used to transport the battery pack to the front side of the U-shaped seat 2, and the unloading trolley is used to transport the flipped battery pack away.

[0055] When the loading trolley 18 delivers the battery pack to the front of the U-shaped seat 2, the light from the first through-beam sensor 164 is blocked. At this time, the first spinning cylinder 161 is activated, causing its pressure rod to engage with the back of the limiting block 181 of the loading trolley 18, thus limiting the loading trolley 18 and facilitating the loading of the battery pack. The first hydraulic buffer 162 acts as a buffer during this process, and the third flow bar 163 acts as a guide.

[0056] When the unloading trolley moves to the rear of the U-shaped seat 2, the light from the second through-beam sensor 174 is blocked. At this time, the second spinning cylinder 171 is activated, causing its pressure rod to engage with the back of the unloading trolley's limiting block 191, thus limiting the unloading trolley and facilitating the unloading of the battery pack. The second hydraulic buffer 172 acts as a buffer during this process, and the fourth flow bar 173 acts as a guide.

[0057] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
