The lifting mechanism 200 is arranged in the outer frame 100, the positioning and lifting mechanism 300 is arranged in the bottom center of the lifting mechanism 200, the clamping and flipping mechanism 400 includes a frame 410, a side clamping assembly 420, a tooling plate clamping assembly 430 and a flipping assembly 440. The frame 410 is arranged in the top of the lifting mechanism 200 and is rotatably matched with the lifting mechanism 200. The side clamping assembly 420 is arranged in the frame 410, the tooling plate clamping assembly 430 is symmetrically arranged on the frame 410 along the longitudinal direction, and the flipping assembly 440 is installed on the top of the lifting mechanism 200 to provide power for the frame 410 to rotate. The battery pack is clamped from four sides by the side clamping assembly 420, and the tooling plate 700 is clamped by the tooling plate clamping assembly 430 and then flipped, which improves the stability of the flipping. Compared with clamping and flipping the battery pack and the tooling plate 700 as a whole, excessive clamping force is not required, thereby avoiding over-pressure damage to the battery pack.

[0040] Specifically, the middle parts of the left and right ends of the frame 410 are rotatably connected to the lifting frame 210 in the lifting mechanism 200 through rotating shafts respectively; the flipping assembly 440 includes a flipping motor and a reducer, and the output end of the flipping motor is connected to one of the rotating shafts through the reducer. This is the prior art and will not be described in detail here.

[0041] like Figure 2 As shown, the side clamping assembly 420 includes a long-side clamping group 421, a short-side clamping group 422 and a driving group 423. The long-side clamping group 421 is symmetrically arranged in the frame 410 along the longitudinal direction, and its left and right ends are respectively slidably connected to the frame 410. The short-side clamping group 422 is symmetrically arranged in the frame 410 along the transverse direction, and its front and rear ends are respectively slidably connected to the frame 410. The driving group 423 is installed on the frame 410 to provide power for the longitudinal movement of the long-side clamping group 421. Due to the sliding connection between the long-side clamping group 421 and the frame 410 and the sliding connection between the short-side clamping group 422 and the frame 410, fast cutting and pulling adjustments can be achieved for battery packs of different sizes, thereby improving compatibility, practicality and flipping efficiency.

[0042] like Figure 2 and Figure 3As shown, the long face clamping group 421 includes a crossbeam 4211, a clamping plate 4212 and a clamping block 4213. The left and right ends of the crossbeam 4211 are respectively slidably connected to the frame 410. The clamping plate 4212 is composed of a plurality of pieces, which are distributed on the inner side of the crossbeam 4211 in the transverse direction. The clamping block 4213 is composed of a plurality of pieces, which are arrayed on the inner side of the clamping plate 4212. The driving end of the driving group 423 is connected to the end of the crossbeam 4211. Specifically, the left and right ends of the crossbeam 4211 are respectively slidably connected to the frame 410 through an L-shaped plate; the driving group 423 can be an electric cylinder, and its driving end is connected to the L-shaped plate. The left and right ends of the crossbeam 4211 correspond to a group of driving groups 423.

[0043] like Figure 2 and Figure 4 As shown, the short-side clamping group 422 includes a longitudinal beam 4221, a protection box 4222, a clamping cylinder 4223 and a clamping plate 4224. The front and rear ends of the longitudinal beam 4221 are respectively slidably connected to the frame 410.

The clamping cylinder 4223 is transversely installed in the protection box 4222, and its driving end passes through the protection box 4222 and is connected to the clamping plate 4224. Specifically, the front and rear ends of the longitudinal beam 4221 are respectively installed with guide blocks, which are slidably connected to the guide rails on the inner side of the frame 410. The front and rear ends of the longitudinal beam 4221 are also respectively installed with pneumatic guide rail locks, which are connected to the guide rails. When the longitudinal beam 4221 moves to a predetermined position, the guide rail locks are locked with the guide rails.

[0044] like Figure 2 , Figure 5-Figure 7As shown, the tooling plate clamping assembly 430 includes a guide beam 431, a fixing plate 432, a fixing seat 433, a mounting block 434, a latch 435, a support block 436, an extension cylinder 437, a double-headed cylinder 438, a position block 439 and a driving member 4310. The guide beam 431 is vertically mounted on the outer side of the frame 410. The fixing plate 432 is composed of two pieces, which are respectively arranged above and below the edge of the frame 410. The fixing plate 432 is slidably connected to the guide beam 431. The fixing seats 433 are respectively mounted on the left and right ends of the fixing plate 432. One end of the mounting block 434 is connected to the bottom of the fixing seat 433. The top of the frame 410 is connected to the bottom of the latch 435, and the other end is connected to the bottom end of the latch 435. The support block 436 is slidably connected to the top of the fixed seat 433. The extending cylinder 437 is longitudinally installed on the top of the fixed seat 433, and its driving end extends into the fixed seat 433 and is connected to the support block 436. The double-headed cylinder 438 is transversely installed on the top of the fixed seat 433, and its driving end extends into the fixed seat 433 and is connected to the position block 439. The position block 439 corresponds to the position hole 4361 on the support block 436. The driving member 4310 is vertically installed on the outside of the frame 410, and its driving end is connected to the fixed plate 432. The setting of the double-headed cylinder 438 and the position block 439 limits the stroke of the support block 436 and accurately identifies the original position and working position of the extending cylinder 437. When clamping, the pin 435 is inserted into the socket at the corner of the tooling plate 700, and then the double-headed cylinder 438 drives the position block 439 to withdraw from the position hole 4361, and finally the extended cylinder 437 drives the support block 436 to extend out of the fixed seat 433 to achieve the clamping of the tooling plate 700. Specifically, the driving member 4310 can be an electric cylinder, and there are two driving members 4310, which respectively drive the two fixed plates 432 to move; the pin 435 and the support block 436 above the frame 410 are mirror images of the pin 435 and the support block 436 below the frame 410; the lifting plates 4311 are symmetrically arranged in the middle of the front and rear ends of the frame 410 to support the middle of the tooling plate 700.

[0045] like Figure 8 As shown, the positioning and lifting mechanism 300 is composed of two groups, which are symmetrically arranged in the longitudinal direction. The positioning and lifting mechanism 300 includes a base frame 310, a lifting assembly 320 and a positioning assembly 330. The lifting assembly 320 is arranged in the middle of the base frame 310, and the positioning assemblies 330 are respectively installed at the left and right ends of the base frame 310. The positioning assembly 330 positions the trolley 500, and then the lifting assembly 320 lifts the tooling plate 700 loaded with the battery pack on the trolley 500 for accurate clamping by the clamping and flipping mechanism 400.

[0046] like Figure 8-Figure 10As shown, the lifting assembly 320 includes a slope block 321, a connecting rod 322, a lifting cylinder 323, a lifting plate 324, a roller 325, a ball 326, a limit cylinder 327 and a limit pin 328. The slope block 321 is divided into two pieces, which are arranged in the middle of the base frame 310 along the lateral interval. The slope block 321 is slidably connected to the base frame 310, and the two slope blocks 321 are connected by a connecting rod 322. The lifting cylinder 323 is arranged in the middle of the base frame 310 horizontally, and its driving end It is connected to one of the slope blocks 321, the lifting plate 324 is arranged above the slope block 321 and is slidably connected to the base frame 310, the bottom end of the lifting plate 324 rolls with the slope block 321 through the roller 325, there are a plurality of balls 326, which are arranged at the top of the lifting plate 324 along the lateral intervals, the limit cylinder 327 is vertically installed at one end of the lifting plate 324, the limit pin 328 is installed at the driving end of the limit cylinder 327, and corresponds to the limit hole on the tooling plate 700. During lifting, the lifting cylinder 323 drives one of the slope blocks 321 to move horizontally, and then drives the other slope block 321 to move horizontally synchronously through the connecting rod 322. During the horizontal movement of the two slope blocks 321, the roller 325 rolls on the inclined surface of the slope block 321, thereby forcing the lifting plate 324 to rise until the ball 326 contacts the tooling plate 700. At the same time, the limit cylinder 327 drives the limit pin 328 to enter the limit hole of the tooling plate 700, thereby performing secondary positioning. Then the lifting cylinder 323 continues to drive the tooling plate 700 loaded with the battery pack to rise until it rises to the clamping position.

[0047] like Figure 8 As shown, the positioning assembly 330 includes a positioning cylinder 331, a rotating clamp 332 and a positioning block 333. The positioning cylinder 331 is longitudinally mounted on the base frame 310, and the positioning block 333 is connected to the driving end of the positioning cylinder 331 through the rotating clamp 332. The positioning cylinder 331 drives the rotating clamp 332 to rotate 90°, so that the positioning block 333 limits the trolley 500.

[0048] like Fig.11 As shown, the lifting mechanism 200 includes a lifting frame 210, a lifting electric cylinder 220 and a counterweight assembly 230. The lifting frame 210 is slidably installed in the outer frame 100. The lifting electric cylinder 220 is vertically arranged, and its driving end is connected to the lifting frame 210. The counterweight assembly 230 is respectively installed at the four corners of the outer frame 100 and connected to the lifting frame 210. Through the arrangement of the counterweight assembly 230, the lifting and lowering of the clamping and flipping mechanism 400 is more labor-saving and energy-saving, and has an anti-falling design to improve safety.

[0049] like Fig.11 and Fig.12As shown, the counterweight assembly 230 includes a guide shaft 231, a counterweight group 232, a guide wheel group 233, a double-row chain 234, an anti-fall group 235 and a buffer block 236. There are two guide shafts 231, which are vertically arranged on the outside of the outer frame 100. Both ends of the guide shaft 231 are connected to the outer frame 100 through angle plates 237 respectively. The counterweight group 232 is installed on the guide shaft 231 and slidably cooperates with the guide shaft 231. The guide wheel group 233 is installed at the top of the outer frame 100. One end of the double-row chain 234 is connected to the counterweight group 232 through the anti-fall group 235, and the other end thereof bypasses the guide wheel group 233 and is connected to the lifting frame 210. The buffer block 236 is installed on the angle plate 237. The provision of the buffer block 236 avoids a rigid collision between the counterweight group 232 and the angle plate 237.

[0050] like Figure 12-14 As shown, the anti-fall group 235 includes a U-shaped seat 2351, a bayonet 2352, a locking head 2353, a spring sleeve 2354, an ejector pin 2355, an ejector spring 2356 and a clamping strip 2357. The U-shaped seat 2351 is installed at the top of the weight group 232. The middle part of the bayonet 2352 is rotatably connected to the top of the U-shaped seat 2351, and its top is connected to one end of the double-row chain 234 through the locking head 2353. The spring sleeve 2354 is longitudinally arranged Installed on one side of the bottom of the U-shaped seat 2351, the ejector pin 2355 is slidably installed in the spring sleeve 2354, and its end close to the U-shaped seat 2351 extends out of the spring sleeve 2354 and conflicts with the bottom of the bayonet 2352, the ejector spring 2356 is arranged in the spring sleeve 2354, and conflicts with the end of the ejector pin 2355 away from the U-shaped seat 2351, and the clamping strip 2357 is vertically installed on the outside of the outer frame 100 and corresponds to the bayonet 2352. Under normal circumstances, under the dual effects of the tension of the double-row chain 234 and the gravity of the counterweight group 232, the latch 2352 overcomes the elastic force of the ejection spring 2356 and is in a vertical state. At this time, the bottom end of the latch 2352 is not stuck in the tooth groove of the clamping strip 2357; when an unexpected fall occurs, the tension of the double-row chain 234 disappears, and the elastic force of the ejection spring 2356 drives the latch 2352 to rotate, so that the bottom end of the latch 2352 is stuck in the tooth groove of the clamping strip 2357, thereby realizing the anti-fall function.

[0051] During operation, an unloaded tooling plate 700 is clamped by the latch 435 and the support block 436 above the frame 410, and then the tooling plate 700 loaded with the battery pack is automatically transported by the trolley 500 to the positioning and lifting mechanism 300, the positioning component 330 limits the trolley 500, and the lifting component 320 lifts the tooling plate 700 loaded with the battery pack on the trolley 500 to the clamping position, and the lifting mechanism 200 drives the clamping and flipping mechanism 400 to descend to the clamping position. At this time, the latch 435 below the frame 410 is inserted into the socket of the tooling plate 700 loaded with the battery pack, and the support block 436 below the frame 410 extends out to clamp the tooling plate 700, and the driving member 4310 drives the fixed plate 432 above the frame 410 to descend, thereby driving the unloaded tooling plate 700 to descend and to contact the battery pack At the same time, the driving group 423 drives the long-side clamping group 421 to approach the battery pack to clamp the long side of the battery pack. The clamping cylinder 4223 drives the clamping plate 4224 to approach the battery pack to clamp the short side of the battery pack. Then the lifting mechanism 200 drives the clamping flipping mechanism 400 to rise to the flipping position. The flipping assembly 440 drives the frame 410 to flip 180° to flip the battery pack and its upper and lower tooling plates 700. Finally, the lifting mechanism 200 drives the clamping flipping mechanism 400 to descend to the clamping position again. The battery pack and the tooling plate 700 fall onto the jacking assembly 320. The jacking assembly 320 descends until the battery pack and its lower tooling plate 700 fall onto the trolley 500 and are transported away by the trolley 500. The lifting mechanism 200 drives the tooling plate 700 above the battery pack to rise and reset. In this application, the trolley 500 is used for automatic loading. Compared with the existing manual lifting and loading, it has a higher degree of automation and higher safety.

[0052] Example 2

[0053] like Figure 1 As shown, this embodiment adds a detection mechanism 600 on the basis of implementation 1 to detect the battery packs transported by the trolley 500, thereby avoiding ineffective flipping of unqualified battery packs and further improving the flipping efficiency.

[0054] like Fig.15 and Fig.16As shown, the detection mechanism 600 includes a bottom beam 610, a gantry 620, a rack 630, a motor 640, a gear 650, a linear module 660, a lifting module 670 and a camera assembly 680. There are two bottom beams 610, which are symmetrically arranged on the front and rear sides of the positioning and lifting mechanism 300. The bottom end of the gantry 620 is slidably connected to the top of the bottom beam 610 through a slider 690. The rack 630 is horizontally installed on the top surface of the bottom beam 610 and is located below the slider 690. The motor 640 is vertically installed on the slider 690, and its output end is connected to the gear 650. The gear 650 is meshed with the rack 630. There are two groups of linear modules 660, which are installed at the top of the gantry 620. The lifting module 670 is vertically installed on the slide of the linear module 660. The camera assembly 680 is installed on the slide of the lifting module 670.

[0055] During the inspection, the motor 640 drives the gear 650 to rotate. Due to the meshing of the gear 650 and the rack 630, the slider 690 is forced to move laterally along the bottom beam 610, thereby driving the gantry 620 to move laterally. At the same time, the linear module 660 and the lifting module 670 drive the camera assembly 680 to move longitudinally and vertically, so as to achieve the battery pack inspection without blind spots. The battery packs that fail the inspection are directly discharged from the trolley 500 without the flipping process.

[0056] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
