Description

Technical Field

[0001] This invention relates to the field of lithium battery coating equipment, and particularly to a lithium battery coating equipment. Background Technology

[0002] In the processing of lithium batteries (specifically, rectangular lithium batteries as described in this application), in order to ensure the insulation between two lithium batteries, a layer of insulating varnish is sprayed onto their surface to ensure their insulation performance and corrosion resistance.

[0003] However, existing lithium batteries often experience ink splattering during the coating process, causing ink droplets to fall onto the track, affecting equipment operation and polluting the environment.

[0004] Meanwhile, existing rail transport of lithium batteries generally uses the reciprocating movement of linear guides to achieve processing. However, this production method has a time difference in slider reset and is mainly suitable for shorter production lines, but not for long production lines. Summary of the Invention

[0005] The main objective of this invention is to provide a lithium battery spraying device that enables rapid spraying of lithium batteries and produces a stable insulating layer structure after spraying.

[0006] To achieve the above objectives, the present invention provides a lithium battery spraying device, comprising:

[0007] The production line includes two spaced-apart first production line and second production line (which can be two parallel lines or located at the same horizontal line). The first production line and the second production line have the same structure. The first production line can transport lithium batteries from the front end to the back end, and the second production line can move lithium batteries from the back end to the front end.

[0008] The main transfer station is located at the rear end of the first production line and the rear end of the second production line. The main transfer station is used to move the lithium batteries at the rear end of the first production line to the rear end of the second production line. The main transfer station can also flip the lithium batteries to the uncoated surface.

[0009] The spraying module includes a first gantry frame, a transverse moving frame (which drives the spraying device to move laterally as a whole) mounted on the first gantry frame, a main vertical moving frame (which drives the spraying device to move vertically as a whole) mounted on the transverse moving frame, and an adjusting frame mounted on the main vertical moving frame. The adjusting frame is provided in at least two sets. The adjusting frame is used to install the spraying device. The adjusting frame can drive the spraying device to spray insulating paint on the left and right sides of the lithium battery.

[0010] The adjustment frame is also equipped with a preliminary curing device, which is used to pre-cur the insulating varnish surface.

[0011] The spraying module is provided in multiple sets and is arranged at intervals on the production line.

[0012] In the actual design of this invention, the spraying module and production line are modularized, thereby effectively saving production costs. That is, the production line can be designed with multiple spraying processes according to actual requirements, that is, set up corresponding spraying modules (preferably, the spraying module can spray three sides), and then continue to spray the other three sides in the next process, which makes the spraying structure simpler. Of course, in actual spraying, the paint thickness is sprayed layer by layer, so multiple sets of identical spraying modules can be set up on a single production line to spray the same surface layer by layer, thereby improving production efficiency (therefore, the insulating ink needs to be pre-cured at this time).

[0037] like Figures 1 to 11 As shown, a lithium battery spraying device includes:

[0038] The production line includes two spaced-apart first production line 101 and second production line 102 (which can be two parallel lines or located on the same horizontal line). The first production line 101 and the second production line 102 have the same structure. The first production line 101 can transport the lithium battery 100 from the front end to the rear end, and the second production line 102 can move the lithium battery 100 from the rear end to the front end.

[0039] The main transfer station 200 is located at the rear end of the first production line 101 and the rear end of the second production line 102. The main transfer station 200 is used to move the lithium battery 100 at the rear end of the first production line 101 to the rear end of the second production line 102. The main transfer station 200 can also flip the lithium battery 100 to the uncoated surface.

[0040] The spraying module 7 includes a first gantry frame, a transverse moving frame (which drives the spraying device to move laterally) on the first gantry frame, a main vertical moving frame (which drives the spraying device to move vertically) on the transverse moving frame, and an adjusting frame on the main vertical moving frame. The adjusting frame is provided in at least two sets. The adjusting frame is used to install the spraying device. The adjusting frame can drive the spraying device to spray insulating paint on the left and right sides of the lithium battery 100.

[0041] The adjustment frame is also equipped with a preliminary curing device, which is used to pre-cur the insulating varnish surface.

[0042] The spraying module 7 is provided in multiple sets and is arranged at intervals on the production line.

[0043] In the actual design, the spraying module 7 and the production line are modularized, thereby effectively saving production costs. That is, the production line can be designed with multiple spraying processes according to actual requirements, that is, set up corresponding spraying modules 7 (preferably, the spraying module 7 can spray 3 sides), and then continue to spray the other three sides in the next process, which makes the spraying structure simpler. Of course, in actual spraying, the paint thickness is sprayed layer by layer, so multiple sets of identical spraying modules 7 can be set up on a single production line to spray the same surface layer by layer, thereby improving production efficiency (therefore, the insulating ink needs to be pre-cured at this time).

[0044] Specifically, the first production line 101 and the second production line 102 are circular conveyor lines, and the circular conveyor line includes:

[0045] The frame 1 has a drive shaft 11 and a driven shaft 12 at its front and rear ends, and the drive shaft 11 is connected to the rotating device.

[0046] The transmission chain 2 is arranged in a closed loop. The drive shaft 11 and the driven shaft 12 are respectively provided with drive gear 13 and driven gear 14 that cooperate with the two ends of the inner circumference of the transmission chain 2. The transmission chain 2 is composed of multiple chain plates that are pivotally connected to each other.

[0047] The chain plate is provided with a carrier plate 6, which is used to place the lithium battery 100. The diameter of the carrier plate 6 is larger than the diameter of the chain plate and can extend out of both sides of the frame 1.

[0048] Upper covers 31 are provided on both sides of the upper transmission chain 2, and the upper wall of the chain plate is higher than the upper wall of the upper cover 31.

[0049] In the actual design, the carrier is set as a universal structure for two or more batteries. When using a smaller battery, the smaller battery can be placed directly on the positioning seat 62, and the suction cup 63 can directly adsorb and fix the smaller battery. The first and second paper boxes are located on the periphery of the smaller battery, so that the ink on the periphery of the lithium battery 100 can be received.

[0050] When transporting large-sized lithium batteries 100, the lithium batteries 100 are placed vertically, with the periphery of the lithium batteries 100 located between the first and second cardboard boxes, and the middle position of the lithium batteries 100 facing the suction cup 63, thus achieving a good adsorption and fixation effect.

[0051] The equipment achieves versatility, while the design of the first and second paper boxes facilitates ink reception and avoids contaminating the equipment.

[0052] Specifically, the frame 1 is provided with a support frame 32 on the inner side of the transmission chain 2. The support frame 32 and the upper cover 31 form a guide groove 3 for the transmission chain 2. The frame 1 is provided with an I-beam 4 in the middle. The support frame 32 is provided with the upper end and the lower end of the I-beam 4. The guide groove 3 plays a supporting and guiding role, ensuring the stable operation of the transmission chain 2.

[0053] More specifically, a pivot 22 is provided between the two chain plates, with both ends of the pivot 22 abutting against the end faces of the support frame 32; the width of the pivot 22 is adapted to the width of the guide groove 3; a first arc-shaped portion 51 extends from the lower part of one end of the chain plate, and a second arc-shaped portion 52, which cooperates with the first arc-shaped portion 51, extends from the upper part of the other end. The pivot 22 allows the upper cover 31 to limit and support the chain plate, ensuring the stable operation of the transmission chain.

[0054] The carrier plate 6 includes:

[0055] The base 61 has an upwardly extending positioning seat 62 in the middle, and the positioning seat 62 has a plurality of spaced suction cups 63.

[0056] The base 61 has upwardly extending positioning strips 64 on both longitudinal sides, and the positioning strips 64 and the positioning seat 62 form a first slot, which is used to install the first cardboard box.

[0057] The base 61 has detachable second cardboard boxes on both sides of its lateral direction.

[0058] In this invention, the width of the lithium battery 100 is smaller than the spacing between the positioning strips 64; the length of the lithium battery 100 is smaller than the maximum length of the two second paper boxes; the upper end of the positioning strip 64 and the upper end of the positioning seat 62 are respectively provided with opposing baffles 65, and the first paper box can be placed inside the baffles 65; the second paper box is a hollow cuboid shape.

[0059] Specifically, the spraying device includes a top spraying device 71 and a side spraying device, wherein the top spraying device 71 is mounted on the main vertical moving frame (the main vertical slider).

[0060] The side spraying device is located on both sides of the main vertical moving frame and has branch vertical moving frames (i.e., the structure of vertical guide rail, vertical slider and telescopic motor or vertical screw pair). The side spraying device is set on the branch vertical moving frame. The top spraying device 71 has a top spraying surface, which is set downward. The top spraying device 71 is used to spray the top surface of the lithium battery 100.

[0061] In this embodiment of the invention, the side spraying device 72 includes a branch transverse moving seat disposed on a branch moving frame. The branch transverse moving seat is provided with two seats and a rotating seat is installed on each seat. The side spraying device is disposed on the rotating seat, that is, the two side spraying devices can move between positions close to each other and positions far apart from each other, and can swing relative to each other. That is, when the spraying surface is facing down, the nozzle is cleaned, and when the two spraying surfaces are facing each other, insulating paint is sprayed onto the side wall of the lithium battery 100.

[0062] Specifically, the main transfer station 200 includes a second gantry 201, a horizontal transfer frame 202 disposed on the second gantry, a vertical transfer frame 203 disposed on the horizontal transfer frame, a horizontal transfer rotating device 204 disposed on the vertical transfer frame, a clamping seat 205 disposed on the horizontal transfer rotating device, and two spaced-apart axis rotating devices 206 disposed on the clamping seat, wherein the axis rotating device is provided with grippers 207.

[0063] The vertical moving frame of the horizontal moving frame adopts the existing drive method of guide rail, slider and lead screw pair, while the horizontal rotating device and the circumferential rotating device adopt the drive method of rotary motor with pivot hole and rotating shaft connected to rotating shaft, thus realizing multiple flips in a single workstation.

[0064] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
