[0055] CombinationFigures 1-3 A water-cooled plate pre-assembly device, comprising:

[0056] Base 100;

[0057] The first adjustable frame includes a first lateral support frame and a second lateral support frame that are slidably connected to the base 100. The distance between the first lateral support frame and the second lateral support frame is adjustable to adapt to the length direction of the water-cooled plate.

[0058] A water-cooled plate conveyor line is located within a first adjustable frame. The water-cooled plate conveyor line includes at least two stepping tables slidably connected to a base 100. Each stepping table has multiple stations for conveying water-cooled plates. A drive assembly is provided between two adjacent stepping tables, which drives the stepping tables to move one station along the conveying direction of the water-cooled plate conveyor line. Each stepping table has a lifting drive source at both the starting and ending stations for lifting the water-cooled plates. The lifting drive source has two lifting strokes.

[0059] Multiple water-cooled plate clamping components 900 are disposed on the first adjustable frame and the water-cooled plate conveying line; at least two water-cooled plate clamping components 900 are used to clamp the water-cooled plates.

[0060] This embodiment provides a water-cooled plate pre-assembly device that is compatible with water-cooled plates of different sizes and specifications, such as water-cooled plates with a length of 800mm-1500mm and a width of 70mm-130mm. It has functions such as a protective sleeve for pulling out water nozzles, inserting water-cooling pipes, and detection, thereby improving production efficiency and reducing labor costs.

[0061] In this embodiment, the workstations along the conveying direction of the water-cooled plate conveyor line sequentially include a loading station 200, a cap removal station 300, a first inspection station 401, a tube insertion station 500, a second inspection station 402, a shaping station 600, and a unloading station 700. The water-cooled plate is placed at the loading station 200, which then conveys it to the cap removal station 300 via a stepper motor. After removing the protective sleeve from the water-cooled plate, the cap removal station 300 conveys it to the first inspection station 401 via a stepper motor. After the first inspection station 401 checks whether the protective sleeve of the water-cooled plate has been removed, the water-cooled plate is conveyed to the tube insertion station 500 by stepping. After the tube insertion station 500 inserts the pipe into the inlet and outlet of the water-cooled plate, the water-cooled plate is conveyed to the second inspection station 402 by stepping. After the second inspection station 402 checks whether the pipe of the water-cooled plate is assembled in place, the water-cooled plate is conveyed to the shaping station 600 by stepping. After the shaping station 600 corrects the water-cooled plate, the water-cooled plate is conveyed to the unloading station 700 by stepping.

[0062] Furthermore, both the loading station 200 and the unloading station 700 are equipped with two sets of water-cooled plate clamping components 900. One set of water-cooled plate clamping components 900 is fixed, while the other set is movable and can be raised and lowered. This design is mainly to allow two water-cooled plates to be placed at the same time. One set of water-cooled plate clamping components 900 is fixed, while the other set can be raised by a cylinder to achieve the height difference.

[0063] Preferably, a collection box for collecting the protective sleeves removed from the water nozzles of the water-cooling plate can also be installed at the cap removal station 300.

[0064] In this embodiment, as Figure 4 As shown, the first adjustable frame includes a base frame 101 and a connecting frame 102 disposed on the base frame 101. The connecting frame 102 is used to support the stepping platform. Specifically, the connecting frame 102 includes two parallel steel beams.

[0065] Furthermore, a second guide rail 108 is provided on the basic frame 101, and a first guide rail 107 is provided on the connecting frame 102, wherein the second guide rail 108 is arranged to avoid the first guide rail 107.

[0066] Preferably, limiting blocks 109 are provided at the extreme positions on both sides of the second guide rail 108 to limit

[0067] The distance between the first lateral shift support frame and the second lateral shift support frame is adjusted by a first drive assembly. Specifically, the first drive assembly includes a first motor 103, four lead screws 104, and a commutator 105. For ease of description, the four lead screws 104 are defined as the first lead screw, the second lead screw, the third lead screw, and the fourth lead screw, respectively. The first motor 103 has two opposing output ends, which are respectively connected to the first lead screw and the second lead screw. The third lead screw and the fourth lead screw are parallel to each other and both pass through the base frame 101. A commutator 105 is provided between the first lead screw and the third lead screw, and power is transmitted through the commutator 105. Similarly, a commutator 105 is provided between the second lead screw and the fourth lead screw, and power is transmitted through the commutator 105. Multiple nuts 106 are provided on both the third lead screw and the fourth lead screw, and the nuts 106 are connected to the first adjustable frame. The first lead screw 104 can be an integral structure or a segmented structure connected by a coupling.

[0068] The first lateral shift support frame and the second lateral shift support frame have the same structure, specifically, as follows: Figure 5As shown, the first lateral shift support frame includes a third crossbeam 121, a third movable frame 123, and a fourth movable frame 124. Multiple connecting rods 122 connect the third crossbeam 121 and the third movable frame 123. The third movable frame 123 and the fourth movable frame 124 are flush and slidably connected to the second guide rail 108. When the first motor 103 is started, it drives the first, second, third, and fourth lead screws to rotate synchronously. This, in turn, causes the third movable frame 123 and the fourth movable frame 124 to move on the second guide rail 108 via a nut 106, thereby adjusting the distance between the first and second lateral shift support frames. The third crossbeam 121 is equipped with multiple water-cooled plate clamping components 900.

[0069] Furthermore, during the corresponding process operations at the cap removal station 300 and the tube insertion station 500, it is necessary to ensure the positioning accuracy of the water-cooled plate. Therefore, the first adjustable frame also includes a first adjustable component. The first adjustable component includes a fourth motor 801, a synchronous pulley assembly 802 connected to the output end of the fourth motor 801, and a transmission screw connected to the water-cooled plate clamping component 900. The transmission screw and the synchronous pulley assembly 802 are connected. The spacing between two adjacent water-cooled plate clamping components 900 along the conveying direction of the water-cooled plate conveying line is adjustable through the first adjustable component to adapt to the width direction of the water-cooled plate. Specifically, the synchronous pulley assembly 802 includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt tensioned on the first and second synchronous pulleys. The output end of the fourth motor 801 is connected to the first synchronous pulley, the rod of the transmission screw passes through the second synchronous pulley, and the water-cooled plate clamping components 900 set on the third crossbeam 121 are all connected to the nuts of the transmission screw. The fourth motor 801 drives the first synchronous pulley to rotate, and the first synchronous pulley transmits power to the second synchronous pulley, which drives the transmission screw to rotate, thereby adjusting the distance between two adjacent water-cooled plate clamping components 900 on the third crossbeam 121 to adapt to the width direction of the water-cooled plate.

[0070] In this embodiment, as Figure 6 As shown, there are two stepper stages, namely the first stepper stage and the second stepper stage.

[0071] Combination Figure 8 and Figure 9The first step of the platform includes a first crossbeam 111, a first load-bearing frame 112, a first support 113, a second support 114, and a first movable frame 115. The first movable frame 115 is slidably connected to a first guide rail 107. The first support 113 and the second support 114 are respectively located on both sides of the first movable frame 115 and support the first load-bearing frame 112. There are two first crossbeams 111, which are arranged parallel to each other on the first load-bearing frame 112. Multiple water-cooled plate clamping components 900 are provided on the first crossbeams 111, and the spacing between the two first crossbeams 111 is adjustable. A first double-stroke cylinder 201 is provided at the first support 113, and a second double-stroke cylinder 403 is provided at the second support 114. The working ends of the first double-stroke cylinder 201 and the second double-stroke cylinder 403 can pass through the two first crossbeams 111 to contact the water-cooled plates.

The second rack 301 and the third rack 303 are arranged opposite to each other. The second rack 301 and the third rack 303 are both meshed with the second gear 302. The second gear 302 is connected to the output end of the fifth motor. The fifth motor drives the second gear 302 to rotate. The second gear 302 and the second rack 301 mesh with the third rack 303 to drive the two first crossbeams 111 to move closer or further apart.

[0073] Combination Figure 10 and Figure 11 The second stepping platform includes a second crossbeam 116, a second supporting frame 117, a third support 118, a fourth support 119, and a second moving frame 120. The second moving frame 120 is slidably connected to the first guide rail 107. The third support 118 and the fourth support 119 are respectively located on both sides of the second moving frame 120 and support the second supporting frame 117. There are two second crossbeams 116, which are arranged parallel to each other on the second supporting frame 117. Multiple water-cooled plate clamping components 900 are provided on the second crossbeams 116, and the spacing between the two second crossbeams 116 is adjustable. A third double-stroke cylinder 501 is provided at the third support 118, and a fourth double-stroke cylinder 701 is provided at the fourth support 119. The working ends of the third double-stroke cylinder 501 and the fourth double-stroke cylinder 701 can pass through the two first crossbeams 111 to contact the water-cooled plates.

[0074] The adjustable spacing between the two second crossbeams 116 is as follows: the bottom of the two second crossbeams 116 is provided with a third connecting plate and a fourth connecting plate, the bottom of the third connecting plate is provided with a fourth rack 601, and the bottom of the fourth connecting plate is provided with a fifth rack 603. The fourth rack 601 and the fifth rack 603 are arranged opposite to each other. The fourth rack 601 and the fifth rack 603 are both meshed with the third gear 602. The third gear 602 is connected to the output end of the sixth motor. The sixth motor drives the third gear 602 to rotate. The fourth rack 601 and the fifth rack 603 mesh with the third rack 603 to drive the two second crossbeams 116 closer to or further apart.

[0075] In this embodiment, as Figure 12 As shown, the insertion station 500 is equipped with a clamping mechanism (not shown) and / or a positioning mechanism, which are used to restrict the movement of the water-cooling plate. Preferably, the insertion station 500 is equipped with both a clamping mechanism and a positioning mechanism. The clamping mechanism includes a lifting cylinder and a pressure plate connected to the working end of the lifting cylinder. The retraction of the working end of the lifting cylinder can drive the pressure plate to clamp the water-cooling plate. The positioning mechanism includes a third motor 502, a pushing cylinder 503, a sliding plate 504, and a positioning block 505. The output end of the third motor 502 is connected to the sliding plate 504. The pushing cylinder 503 is mounted on the sliding plate 504, and the working end of the pushing cylinder 503 is connected to the positioning block 505. The positioning block 505 and the sliding plate 504 are slidably connected. The positioning block 505 has at least two U-shaped grooves of different sizes. The third motor 502 drives the slide plate 504 to move along the conveying direction of the water-cooled plate conveyor line. After the slide plate 504 reaches the designated position, it pushes the cylinder 503 to push the positioning block 505 close to the water-cooled plate. According to the size of the water nozzle of the water-cooled plate, the corresponding U-shaped groove is selected so that the water nozzle of the water-cooled plate is inserted into the U-shaped groove of the positioning block 505, so as to prevent the water-cooled plate from shifting during the water pipe insertion process, which would result in unqualified pipe insertion.

[0076] In this embodiment, combined with Figure 6 and Figure 7 The drive assembly includes a second motor 110, a first rack 125, and a first gear 126. The second motor 110 is located between the first step feed stage and the second step feed stage and is mounted on the support plate. The output end of the second motor 110 is connected to the first gear 126, and the first gear 126 and the first rack 125 mesh and drive each other. The two sides of the support plate are respectively connected to the first step feed stage and the second step feed stage.

[0077] The working principle of this embodiment is as follows:

[0078] Adjust the spacing between the first and second lateral shift support frames according to the length of the water-cooled plate to be transported;

[0079] The lifting drive source lifts the first stroke, the water-cooled plate clamping component 900 clamps the water-cooled plate, the lifting drive source lifts the second stroke, the drive component drives the stepping table to move one station along the conveying direction of the water-cooled plate conveying line, and conveys the water-cooled plate from the loading station 200 to the cap removal station 300 for the removal of the protective sleeve.

[0080] When the lifting drive source descends to the first stroke, the water-cooled plate clamping component 900 is released, the lifting drive source descends to the initial state, and the drive component drives the stepping table to return to the loading station 200 along the conveying direction of the water-cooled plate conveyor line, completing one stepping cycle.

[0081] Similarly, the transfer of water-cooled plates between the cap removal station 300 and the first inspection station 401, between the first inspection station 401 and the tube insertion station 500, between the tube insertion station 500 and the second inspection station 402, between the second inspection station 402 and the shaping station 600, and between the shaping station 600 and the unloading station 700 all follow the above-mentioned stepping cycle, which will not be described in detail here.

[0082] This embodiment also provides a battery production line, including the water-cooled plate pre-assembly device as described above.

[0083] It should be noted that the main design feature of this invention is the structure of the water-cooled plate pre-assembly device. The mechanical structure and processes of other assembly stations in the battery production line, such as the cell assembly station and the module assembly station, will not be described in detail.
