Detailed Implementation

[0033] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0034] Example 1

[0035] like Figure 1 and Figure 2As shown, a battery cell assembly transfer station includes a worktable 100 with a longitudinal hole 110 on its surface. It also includes a lifting and transfer mechanism 200 disposed within the worktable 100, two large sliding plates 300 symmetrically arranged laterally on both sides of the longitudinal hole 110 and slidably connected to the worktable 100, a power mechanism 400 mounted on the worktable 100 and driving the large sliding plates 300 to move laterally, an assembly mechanism 500 disposed in the middle of the two large sliding plates 300 and pressing double rows of battery cells, a shaping and positioning mechanism 600 mounted on the large sliding plates 300, and a terminal post pressing mechanism 700 mounted on the worktable 100 and spanning the middle of the two large sliding plates 300. The top of the lifting and transfer mechanism 200 protrudes from the longitudinal hole 110. Specifically, a coordinate measuring module 1000 is also installed on the worktable 100.

[0036] The large sliding plate 300 is driven laterally by the power mechanism 400 to achieve compatibility in the length direction of the battery cell. Combined with the shaping and positioning mechanism 600, compatibility in the width direction of the battery cell is achieved. This enables full compatibility without replacing any components, and the structure is simple, low-cost, and space-saving. Meanwhile, the grouping mechanism 500 and the terminal pressing mechanism 700 are both located in the middle of the two large sliding plates 300, concentrating them in one location for high integration and further reducing space requirements.

[0037] like Figure 2 and Figure 3 As shown, the lifting and transfer mechanism 200 includes a lower base plate 210, a transfer module 220, a mounting frame 230, a lifting plate 240, a lifting assembly 250, and a clamping assembly 260. The lower base plate 210 is longitudinally installed within the worktable 100. The transfer module 220 is longitudinally installed on the lower base plate 210. The bottom end of the mounting frame 230 is connected to the upper slider of the transfer module 220. The lifting plate 240 is positioned directly above the mounting frame 230. The lifting assembly 250 is vertically installed at the top center of the mounting frame 230. The drive end of the lifting assembly 250 is connected to the lifting plate 240. Several clamping assemblies 260 are arranged in an array at the top of the lifting plate 240. Specifically, the transfer module 220 is a linear module; the lifting assembly 250 is an electric cylinder lifter; four clamping assemblies 260 are arranged in pairs facing each other; the lifting and transfer mechanism 200 can transfer four sets of double-row battery cells at a time.

[0038] When transporting the double-row battery cells, the clamping component 260 clamps the double-row battery cells, the lifting component 250 drives the lifting plate 240 to rise and lift the double-row battery cells, and then the transfer module 220 drives the mounting frame 230 to move longitudinally to realize the longitudinal transport of the double-row battery cells.

[0039] like Figures 3-5As shown, the clamping assembly 260 includes a keel plate 261, a base frame 262, a fixed gripper 263, a movable gripper 264, a floating seat 265, a gasket 266, a floating shaft 267, a first floating component 268, and a driving component 269. The keel plate 261 is longitudinally mounted on the top of the lifting plate 240. There are two base frames 262, which are longitudinally spaced on the right side of the keel plate 261. The fixed gripper 263 is vertically mounted on the right end of the base frame 262. The movable gripper 264 is arranged opposite to the fixed gripper 263. The floating seat 265 is slidably connected to the keel plate 261. The bottom end of the movable gripper 264 is connected to the floating seat 265. The gasket 266 is mounted on... On the base frame 262, two floating seats 265 are connected by a floating shaft 267. The right end of the floating shaft 267 is connected to one floating seat 265, and the left end of the floating shaft 267 is slidably connected to the other floating seat 265 and extends into a stepped hole 2651 opened at the right end of the floating seat 265. A first floating member 268 is sleeved on the left end of the floating shaft 267. The left end of the first floating member 268 abuts against the step of the stepped hole 2651, and the right end of the first floating member 268 abuts against the flange on the floating shaft 267. A driving member 269 is longitudinally installed on the left side of the keel plate 261, and the driving end of the driving member 269 is connected to the other floating seat 265. Specifically, the first floating member 268 is a spring; the driving member 269 is a cylinder.

[0040] During operation, the battery cell is placed on the base frame 262. The drive unit 269 drives one floating seat 265 to move longitudinally, which in turn drives another floating seat 265 to move longitudinally via the floating shaft 267. This, in turn, moves the movable gripper 264 closer to the fixed gripper 263, thus clamping the battery cell. The effective stroke of the drive unit 269 is 100mm, ensuring compatibility in the battery cell thickness direction. A first floating element 268 is provided between the two floating seats 265 for floating connection to compensate for differences between individual battery cells of the same blueprint.

[0041] The power mechanism 400 includes a lead screw, a lead screw nut, and a power assembly. The lead screw is horizontally mounted on the worktable 100. The lead screw nut is threaded onto the lead screw. The top of the lead screw nut is connected to the bottom of the large slide plate 300. The power assembly is connected to the lead screw for transmission. This is existing technology, and its working principle will not be described in detail here.

[0042] like Figure 1 and Figure 6 As shown, the grouping mechanism 500 includes a reference assembly 510 and a pressurizing assembly 520, which are mounted opposite each other in the middle of two large sliding plates 300. When the dual-row cells are grouped, the reference assembly 510 provides reference-side support, and the pressurizing assembly 520 provides pressurizing force.

[0043] like Figure 6 and Figure 7As shown, the reference assembly 510 includes a reference base 511, a reference component 512, a transition plate 513, a load cell 514, a reference plate 515, and a guide group 516. The reference base 511 is vertically mounted in the middle of a large sliding plate 300. The reference component 512 is horizontally mounted on the reference base 511. The transition plate 513 is mounted on the drive end of the reference component 512. The reference plate 515 is located on the side of the transition plate 513 away from the reference component 512. The reference plate 515 is connected to the transition plate 513 via the guide group 516. The load cell 514 is located between the transition plate 513 and the reference plate 515 for pressure monitoring. Specifically, the reference component 512 is a cylinder; the guide group 516 includes a guide shaft and a bushing, which is prior art.

[0044] like Figure 6 and Figure 8 As shown, the pressurizing assembly 520 includes a pressurizing base 521, a pressurizing component 522, a pressurizing plate 523, and a first pressure-reducing valve 524. The pressurizing base 521 is vertically mounted in the middle of another large sliding plate 300. The pressurizing component 522 is horizontally mounted on the pressurizing base 521. The pressurizing plate 523 is mounted on the driving end of the pressurizing component 522. The first pressure-reducing valve 524 is mounted on the pressurizing base 521 and is used to adjust the pressurizing pressure. Specifically, the pressurizing component 522 is a cylinder.

[0045] When assembled, the pressure component 522 drives the pressure plate 523 to move towards the reference plate 515, squeezing the double-row cells from the length direction, and the small faces of the double-row cells are put together.

[0046] like Figure 1 , Figure 2 and Figure 6 As shown, the shaping and positioning mechanism 600 includes an outer shaping component 610 and a middle shaping component 620. Multiple outer shaping components 610 are installed longitudinally at intervals at opposite ends of two large sliding plates 300. Multiple middle shaping components 620 include a longitudinal beam 621 and a middle shaping group 622. The longitudinal beam 621 is positioned between the two large sliding plates 300, with both ends connected to the worktable 100. Multiple middle shaping groups 622 are installed longitudinally at intervals on the longitudinal beam 621. Specifically, the structures of the outer shaping components 610 and the middle shaping groups 622 are the same as those of the clamping components 260. Both the outer shaping components 610 and the middle shaping groups 622 consist of three groups, with the middle group corresponding to the grouping mechanism 500. The middle shaping components 620 are positioned between the two opposing clamping components 260. The pads 266 in the outer shaping assembly 610 and the middle shaping assembly 622 ensure the flatness of the bottom after the battery cells are assembled.

[0047] like Figure 1 and Figure 9As shown, the pole pressing mechanism 700 includes a gantry frame 710, a pressing member 720, an adapter plate 730, a pressing block 740, a guide assembly 750, a second floating member 760, and a second pressure reducing valve 770. The gantry frame 710 is mounted on the workbench 100 and spans the middle of two large sliding plates 300. The pressing member 720 is vertically mounted in the middle of the gantry frame 710. The adapter plate 730 is mounted on the driving end of the pressing member 720. The pressing block 740 is located directly below the adapter plate 730 and is connected to the adapter plate 730 via the guide assembly 750. The second floating member 760 is located between the adapter plate 730 and the pressing block 740. One end of the second floating member 760 abuts against the adapter plate 730, and the other end of the second floating member 760 abuts against the pressing block 740. The second pressure reducing valve 770 is mounted on the gantry frame 710 and is used to adjust the magnitude of the pole pressing pressure. Specifically, the pressing component 720 uses a cylinder; a proximity sensor is installed on the adapter plate 730; the pressing block 740 is made of urethane (Shore hardness A90) to ensure that the battery cell will not be damaged during pressing; and the second floating component 760 uses a spring. When the pressing component 720 drives the pressing block 740 to press against the battery cell terminal surface, the second floating component 760 compresses the proximity sensor and receives a signal, at which point the pressing is complete.

[0048] During operation, the ungrouped double-row cells are placed on the outer shaping assembly 610 and the middle shaping assembly 622 at the front of the large sliding plate 300 using a one-grab-two-release method by a small unit gripper (not shown in the figure). This is the upper wire position. The outer shaping assembly 610 and the middle shaping assembly 622 compress and shape the double-row cells in the width direction. The lifting and transfer mechanism 200 lifts and transports the shaped double-row cells to the outer shaping assembly 610 and the middle shaping assembly 622 in the middle of the large sliding plate 300. This is the grouping position. 622 further extrudes and shapes the double-row battery cells. The terminal pressing mechanism 700 presses down on the terminal surfaces of the double-row battery cells, while the grouping mechanism 500 extrudes and groups the double-row battery cells. The lifting and transfer mechanism 200 lifts and transports the grouped double-row battery cells to the outer shaping assembly 610 and the middle shaping assembly 622 at the rear of the large sliding plate 300, i.e., the unloading position. The outer shaping assembly 610 and the middle shaping assembly 622 extrude and shape the double-row battery cells again. The small unit gripper transfers the grouped double-row battery cells to the conveyor belt using a one-grab-two-release method. It should be noted that sensors for detecting battery cell position, battery cell over-height, and battery cell over-width are installed at the upper and lower loading positions.

[0049] Example 2

[0050] like Figure 1 and Figure 2As shown, this embodiment adds a clamping fixture 800 and a transfer mechanism 900 to embodiment 1. The clamping fixture 800 is slidably mounted on the worktable 100, and the transfer mechanism 900 is mounted on the worktable 100 to drive the clamping fixture 800 to move longitudinally. Specifically, two clamping fixtures 800 are provided to form a dual-station, improving work efficiency; the transfer mechanism 900 adopts a linear module. The arrangement of the clamping fixture 800 and the transfer mechanism 900 meets the production requirements of a single row of modules, thereby improving the compatibility and practicality of the equipment.

[0051] like Figure 1 and Figure 10 As shown, the clamping fixture 800 includes a movable plate 810, a central partition assembly 820, a fixed support block 830, a movable support block 840, a first movable assembly 850, a side baffle 860, a side pressure plate 870, and a second movable assembly 880. The movable plate 810 is slidably mounted on the worktable 100 and connected to the drive end of the transfer mechanism 900. Two sets of central partition assemblies 820 are installed laterally at intervals in the middle of the movable plate 810. The fixed support block 830 and the side baffle 860 are both mounted on the worktable 100. The clamping fixture 800 is longitudinally positioned on both sides of the partition assembly 820, the side baffle 860 is transversely positioned on one side of the partition assembly 820, the movable support block 840 is positioned on the side of the fixed support block 830 away from the partition assembly 820, the bottom end of the movable support block 840 is connected to the movable plate 810 through the first movable component 850, and the side pressure plate 870 is transversely positioned opposite the movable support block 840, positioned above the first movable component 850, and connected to the movable plate 810 through the second movable component 880. Specifically, the clamping fixture 800 can hold four battery cells simultaneously; the movable support block 840 is L-shaped.

[0052] The first moving component 850 drives the moving support block 840 to move towards the central partition component 820, and the second moving component 880 drives the side pressure plate 870 to move towards the moving support block 840, thus satisfying full blueprint compatibility.

The lifting component 821 is vertically mounted at the bottom of the moving plate 810, and the partition stop 822 is positioned above the moving plate 810. The driving end of the lifting component 821 passes through the moving plate 810 and connects to the bottom of the partition stop 822. Specifically, the lifting component 821 is a cylinder. The lifting component 821 drives the partition stop 822 to achieve lifting and lowering, meeting the conditions for grabbing the battery cell off the production line.

[0054] like Figure 10 and Figure 11As shown, the first moving component 850 includes a first support plate 851, a first adjusting handle 852, a first toothed block 853, a first elastic element 854, and a first rack 855. The top end of the first support plate 851 is connected to the moving support block 840, and the bottom end of the first support plate 851 is slidably connected to the moving plate 810. The first adjusting handle 852 extends vertically through the first support plate 851. The first toothed block 853 is installed at the bottom end of the first adjusting handle 852. The first elastic element 854 is sleeved on the first adjusting handle 852. The top end of the first elastic element 854 abuts against the first support plate 851, and the bottom end of the first elastic element 854 abuts against the first toothed block 853.
