[0048] See Figure 1 and 5 The present invention proposes a PVC spraying device for a power battery bottom guard plate, comprising:

[0049] At least two spraying platforms 10, which are spaced apart and used to place the power battery bottom guard plate 100 to be sprayed with PVC;

[0050] The spraying mechanism 20 spans above the at least two spraying platforms 10 . The spraying mechanism 20 can move relative to the at least two spraying platforms 10 to spray PVC on the power battery bottom guard plate 100 placed on the at least two spraying platforms 10 .

[0051] In this embodiment, at least two spraying platforms 10 are provided, and a power battery bottom guard plate 100 can be placed on each spraying platform 10. In this way, the power battery bottom guard plates 100 on at least two spraying platforms 10 can be sprayed with PVC simultaneously or separately by the spraying mechanism 20.

[0052] For example, the number of spraying platforms 10 is set to two, and the two spraying platforms 10 are spaced apart below the spraying mechanism 20. In this case, the number of spraying mechanisms 20 can be set to one or two. When the number of spraying mechanisms 20 is set to one, the spraying mechanism 20 first sprays PVC on the power battery bottom guard plate 100 on one of the spraying platforms 10. After the spraying is completed, the spraying mechanism 20 moves to the other spraying platform 10 to spray PVC on the power battery bottom guard plate 100 placed thereon. At the same time, the power battery bottom guard plate 100 that has been sprayed with PVC is unloaded. After unloading is completed, the power battery bottom guard plate 100 to be sprayed with PVC is placed on the spraying platform 10 to wait for the next PVC spraying. This cycle is repeated, thereby achieving non-stop operation of the spraying mechanism 20 and improving the processing efficiency of the power battery bottom guard plate 100.

[0053] When the number of spraying mechanisms 20 is set to two, the two spraying mechanisms 20 simultaneously perform PVC spraying on the power battery bottom guard plates 100 on the two spraying platforms 10. In this way, the PVC spraying operation of the two power battery bottom guard plates 100 can be completed at one time, thereby improving the processing efficiency of the power battery bottom guard plates 100.

[0054] Optionally, a material rack 30 is provided on one side of at least two spraying platforms 10 for stacking the power battery bottom guard plates 100 to be sprayed with PVC. That is, the power battery bottom guard plates 100 to be sprayed with PVC are stacked on the material rack 30 in advance. When the equipment is in operation, the power battery bottom guard plates 100 on the material rack 30 can be transferred by staff or a robot to the at least two spraying platforms 10 for PVC spraying by the spraying mechanism 20.

[0055] Furthermore, the spraying platform 10 may be a frame structure or a plate structure adapted to the size of the power battery bottom guard plate 100 , including but not limited to the above, and those skilled in the art may design it according to actual conditions.

[0056] In some embodiments, see Figures 2 to 4 The spraying mechanism 20 proposed in the embodiment of the present invention includes:

[0057] Frame 21;

[0058] A first driving module 22 is provided on the frame 21;

[0059] The spray head 23 is drivingly connected to the output execution end of the first driving module 22 , and the first driving module 22 drives the spray head 23 to move toward the at least two spraying platforms 10 .

[0060] In this embodiment, the spray head 23 is used to spray PVC. The output actuator end of the first drive module 22 is transmission-connected to the spray head 23 to drive the spray head 23 toward at least two spray platforms 10. The first drive module 22 includes an XYZ three-axis motion module to respectively drive the spray head 23 along the X-axis, Y-axis, and Z-axis.

[0061] Exemplarily, the frame 21 is arranged in a rectangular shape, an X-axis motion module and a Z-axis motion module are arranged on one long side of the frame 21, a Y-axis motion module is arranged on the two short sides of the frame 21, and at least two spraying platforms 10 are arranged at intervals in the rectangular frame 21.

[0062] In some embodiments, see Figure 4 The spraying mechanism 20 proposed in the embodiment of the present invention further includes:

[0063] The second driving module 24 is connected to the output execution end of the first driving module 22 and the spray head 23 respectively, and is used to drive the spray head 23 to rotate and spray PVC.

[0064] In this embodiment, to improve the spraying quality, a second drive module 24 is provided between the first drive module 22 and the spraying mechanism 20. The second drive module 24 is used to drive the spray head 23 to rotate, thereby achieving rotary spraying of the power battery bottom guard plate 100. The rotary spraying of PVC can make the PVC sprayed on the surface of the power battery bottom guard plate more uniform and smooth, thereby achieving the purpose of improving the spraying quality.

[0065] Exemplarily, the second driving module 24 is a rotary cylinder, which is mounted on a mounting base connected to the output execution end of the first driving module 22 , and the piston cylinder of the rotary cylinder is connected to the spraying mechanism 20 to drive the spraying mechanism 20 to rotate.

[0066] In some embodiments, see Figure 1 and 2 The PVC spraying equipment for the power battery bottom guard plate proposed in the embodiment of the present invention also includes at least two conveying mechanisms 40, each of which is arranged corresponding to one of the spraying platforms 10, and the conveying mechanism 40 is used to convey the power battery bottom guard plate 100 in the loading area to the spraying area of ​​the spraying platform 10, and to convey the power battery bottom guard plate 100 in the spraying area to the unloading area.

[0067] In this embodiment, to further improve the processing efficiency of the power battery bottom guard plate 100, each spraying platform 10 is correspondingly provided with a conveying mechanism 40, so as to realize automatic conveying of the power battery bottom guard plate 100 through the conveying mechanism 40. Specifically, the PVC spraying equipment for the power battery bottom guard plate has a loading area, a spraying area, and a unloading area. The loading area is used to convey the power battery bottom guard plate 100 to be sprayed with PVC to a first position on the conveying mechanism 40. The spraying area is used to convey the power battery bottom guard plate 100 to be sprayed with PVC to a second position where at least two spraying platforms 10 are located. The unloading area is used to convey the power battery bottom guard plate 100 that has been sprayed with PVC to a third position in a predetermined area.

[0068] For example, the transport mechanism 40 may be an XYZ three-axis motion module or a multi-joint robotic arm, and those skilled in the art may design it according to actual conditions.

[0069] In some embodiments, see Figure 5 and 6 Each of the transport mechanisms 40 proposed in the embodiment of the present invention includes:

[0070] The translation assembly 41 is provided below the spraying platform 10 and can transport the power battery bottom guard plate 100 between the loading area, the spraying area and the unloading area of ​​the power battery bottom guard plate 100;

[0071] The lifting assembly 42 is in transmission connection with the translation assembly 41 and is used to drive the translation assembly 41 to move in the vertical direction.

[0072] In this embodiment, when the PVC spraying equipment for the power battery bottom guard plate is in operation, the translation assembly 41 moves to the loading area for loading. After loading is completed, the jacking assembly 42 lifts the translation assembly 41 so that the power battery bottom guard plate 100 is located above the spraying platform 10. Then, the translation assembly 41 moves the power battery bottom guard plate 100 to the spraying area, that is, the spraying platform 10. The jacking assembly 42 then drives the translation assembly 41 to move vertically downward so that the power battery bottom guard plate 100 is placed on the spraying platform 10. After the spraying mechanism 20 completes the PVC spraying of the power battery bottom guard plate 100, the translation assembly 41 moves the power battery bottom guard plate 100 to the unloading area. The spraying platform 10 is arranged in a frame structure. The translation assembly 41 can move below the spraying platform 10 and can place the power battery cover plate on the spraying platform 10 under the drive of the jacking assembly 42.

[0073] In some embodiments, see Figure 6 , the translation component 41 proposed in the embodiment of the present invention includes:

[0074] The transport rack 411 is formed with a plurality of placement positions for placing the power battery bottom guard plate 100;

[0075] The third driving module 412 has an output execution end connected to the transport frame 411 and is used to drive the transport frame 411 to move between the loading area, the spraying area and the unloading area of ​​the power battery bottom guard plate 100 .

[0076] In this embodiment, the transport rack 411 is arranged in the shape of a long rectangular strip, and a plurality of crossbeams 413 are arranged at intervals in the length direction thereof, and a plurality of crossbeams 413 form a group to form a placement position for the bottom guard plate 100 of the power battery. Exemplarily, six crossbeams 413 are arranged on the transport rack 411, of which three crossbeams 413 form a group to form a placement position for the bottom guard plate 100 of the power battery, and two groups of crossbeams 413 are arranged at intervals. The third drive module 412 is connected to the translation assembly 41 in a transmission manner, and is used to drive the translation assembly 41 to move along the Y-axis, so that the translation assembly 41 moves between the loading area, the spraying area and the unloading area. Among them, the third drive module 412 can be a Y-axis motion module, that is, a motor + linear module.

[0077] In some embodiments, see Figure 6 The lifting assembly 42 proposed in the embodiment of the present invention includes:

[0078] A lifting plate 421 connected to the translation assembly 41 and used to lift the translation assembly 41 in a vertical direction;

[0079] The fourth driving module 422 has an output execution end connected to the lifting plate 421 and is used to drive the lifting plate 421 to move in the vertical direction.

[0080] In this embodiment, the fourth drive module 422 can be driven by a motor or a linear cylinder. When driven by a motor, the fourth drive module 422 includes not only the power source motor but also a linear module for converting rotational motion into linear motion. Specifically, the fourth drive module 422 includes both the motor and the linear module, and the lift plate 421 is connected to the output actuator end of the linear module. When driven by a linear cylinder, the linear cylinder is arranged vertically, with its piston rod facing and connected to the lift plate 421.

[0081] In some embodiments, see Figure 1 and 2 The PVC spraying equipment for the power battery bottom guard plate proposed in the embodiment of the present invention also includes:

[0082] The unloading machine 50 is located at one end of the translation assembly 41 close to the unloading area, and is used to dock with the translation assembly 41 to transfer the power battery bottom guard plate 100 carried by the translation assembly 41 to a preset position.

[0083] In this embodiment, to further improve the processing efficiency of the power battery bottom guard plate 100, a blanking machine 50 is provided in the blanking area for automatically blanking the PVC-coated power battery bottom guard plate 100. Specifically, when the translation assembly 41 transports the PVC-coated power battery bottom guard plate 100 to the blanking area, the blanking machine 50 docks with the translation assembly 41 to transfer the power battery bottom guard plate 100 onto the blanking machine 50 and transport it to a predetermined area.

[0084] In some embodiments, see Figure 7 The PVC spraying equipment for the power battery bottom guard plate proposed in the embodiment of the present invention further includes a baking oven (not shown) provided on one side of the blanking machine 50, and the blanking machine 50 includes:

[0085] Two bearing members 51 are both extended along the movement direction of the translation assembly 41 and are spaced apart to carry the power battery bottom guard plate 100 that has been sprayed with PVC;

[0086] The transfer module 52 is provided between the two supporting members 51 and can lift the power battery bottom guard plate 100 in the vertical direction and transfer the power battery bottom guard plate 100 to the oven for baking;

[0087] The fifth driving module 53 is used to drive the two supporting members 51 and the transfer module 52 to move between the at least two transport mechanisms 40 .

[0088] In this embodiment, the unloader 50 comprises a rectangular frame for carrying the PVC-coated power battery bottom guard plate 100 and for mounting the transfer module 52. The frame comprises two spaced-apart supporting members. When the power battery bottom guard plate 100 is transported, it is first supported by the two supporting members 51 and then carried by the transfer module 52 and transported to the oven for baking.

[0089] Specifically, when the translation assembly 41 transports the power battery bottom guard plate 100 that has been sprayed with PVC to the unloading area, that is, when the translation assembly 41 carries one end of the power battery bottom guard plate 100 that has been sprayed with PVC and moves it between the two bearings 51, the jacking assembly 42 drives the translation assembly 41 to descend to place the power battery bottom guard plate 100 on the two bearings 51. It should be noted that when the translation assembly 41 transports the power battery bottom guard plate 100 to the unloading area, the translation assembly 41 and the power battery bottom guard plate 100 are still in the jacking state, and the power battery bottom guard plate 100 is located above the two bearings 51. Then, the transfer module 52 starts to operate, first rising in the vertical direction to receive the power battery bottom guard plate 100, and then driving the power battery bottom guard plate 100 in the horizontal direction toward the oven to transport it into the oven for baking.

[0090] After completing the transfer of the power battery bottom guard plate 100 on the current translation assembly 41, the fifth driving module 53 drives the two carriers 51 and the transfer module 52 to move to another translation assembly 41, and repeats the above actions to transfer the other power battery bottom guard plate 100 to the oven for baking.

[0091] Exemplarily, the oven is set at one end of one of the translation components 41. When the unloading machine 50 transfers the power battery bottom guard plate 100, it needs to drive the two supporting parts 51 and the transfer module 52 to move to the oven through the fifth driving module 53.

[0092] In some embodiments, see Figure 8 The transfer module 52 proposed in the embodiment of the present invention includes:

[0093] The conveying mechanism 521 is used to convey the power battery bottom guard plate 100 after PVC spraying toward the oven;

[0094] One end of the scissor mechanism 522 is connected to the conveying mechanism 521 and is used to drive the conveying mechanism 521 to move vertically.

[0095] In this embodiment, the conveyor mechanism 521 can employ either a synchronous pulley or roller structure, and those skilled in the art can design the mechanism based on practical needs. The conveyor mechanism 521 is used to receive the power battery bottom guard plate 100 located on the two support members 51 and to transport the power battery bottom guard plate 100 horizontally into the oven. One end of the scissor mechanism 522 is connected to a power source, such as a motor, and the other end is in driving connection with the bottom of the conveyor mechanism 521 to drive the conveyor mechanism 521 vertically.

[0096] The working principle of the PVC spraying equipment for the power battery bottom guard plate proposed by the present invention is as follows:

[0097] The power battery bottom guard plates 100 to be sprayed with PVC are stacked on the unloading rack 30. During PVC spraying, the third drive module 412 first drives the transport frame 411 to the bottom of the unloading rack 30, where it receives the power battery bottom guard plates 100. After the unloading is complete, the fourth drive module 422 drives the lifting plate 421 upward, lifting the transport frame 411 to a first predetermined position. At this point, the power battery bottom guard plates 100 are positioned above the spraying platform 10. The third drive module 412 then drives the transport frame 411 to the spraying platform 10. After the power battery has reached the second predetermined position on the spraying platform 10, the fourth drive module 422 drives the lifting plate 421 downward, driving the transport frame 411 and the power battery bottom guard plates 100 downward, thereby placing the power battery bottom guard plates 100 on the spraying platform 10. When the power battery bottom guard plate 100 is located on the spraying platform 10 , the spraying mechanism 20 starts to operate to perform PVC rotary spraying on the surface of the power battery bottom guard plate 100 .

[0098] After spraying is completed, the fourth drive module 422 drives the lifting plate 421 to drive the transport frame 411 upward, so that the transport frame 411 docks with the bottom of the power battery bottom guard plate 100 to receive it. Then, the third drive module 412 drives the transport frame 411 and the power battery bottom guard plate 100 to move above the two supporting members 51. After the transport frame 411 and the power battery bottom guard plate 100 are above the two supporting members 51, the fourth drive module 422 drives the transport frame 411 and the power battery bottom guard plate 100 to descend, so that the power battery bottom guard plate 100 is placed on the two supporting members 51. Then, the third drive module 412 drives the transport frame 411 to return to its original position.

[0099] When the power battery bottom guard plate 100 is placed on the two supporting members 51, the scissor mechanism 522 drives the conveying mechanism 521 to rise to receive the power battery bottom guard plate 100 from below the two supporting members 51. At the same time, the fifth driving module 53 drives the two supporting members 51, the scissor mechanism 522 and the conveying mechanism 521 to move to dock with the oven, and then the power battery bottom guard plate 100 is transported to the oven for baking through the conveying mechanism 521.

[0100] It is understood that the above description is the operating principle of one group of spray platforms 10, transport mechanism 40, and unloader 50. The operating principle of the other group is consistent with the above description and will not be repeated here. While the power battery bottom guard plate 100 on one group of spray platforms 10 is being sprayed with PVC, the other group of spray platforms 10 is simultaneously performing other operations, such as loading and unloading.

[0101] Those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples without mutual contradiction.

[0102] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. Any equivalent structural transformation made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields, is included in the scope of protection of the present invention.
