DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with specific implementation methods.

[0028] Battery insulation film spraying equipment such as Figure 1 As shown, it includes a battery loading device 1, a CCD detection device 2, a three-sided spray curing device 3 and an enhanced curing device 4 arranged from left to right. The spraying equipment also includes a battery conveying device (not shown in the figure). The battery conveying device includes a conveyor belt, a battery carrier mounted on the conveyor belt, and a conveying motor that drives the conveyor belt to move. The conveyor belt passes through the battery loading device 1, the CCD detection device 2, the three-sided spray curing device 3 and the enhanced curing device 4 from left to right.

[0029] like Figure 1 As shown, the battery loading device 1 is provided with a closable placement window 11. The operator opens the placement window 11 and sees Figure 2 , the lithium battery 100 (see Figure 3 , which is a rectangular parallelepiped) is loaded into the battery carrier 12 of the battery conveying device. Figure 3 and Figure 4As shown, the battery carrier 12 includes a carrier 120 and a battery clamp composed of a left and right clamping member 121. Since the sizes of lithium batteries 100 of different models are different, in order to be able to adaptively clamp lithium batteries of different sizes, the battery carrier 12 of this embodiment sets the left clamping member 121 to be fixed and the right clamping member 121 to be movable. Specifically: a slideway 127 is opened on the top of the carrier 120 along the length direction of the carrier 120, and the slideway 127 is parallel to the long side of the rectangular carrier 120. The battery carrier 12 also includes an adjustment motor 122 arranged below the slideway 127 and an adjustment screw rod 123 that is transmission-connected to the adjustment motor 122. The right clamping member 121 is arranged in the slideway 127, and the bottom is slidably connected to the above-mentioned adjustment screw rod 123. The operator can operate the adjusting motor 122 to drive the adjusting screw 123 to rotate and drive the right clamping member 121 to move to the right along the adjusting screw 123 according to the size of the lithium battery 100 to be sprayed and cured as needed, until the distance between the left and right clamping members 121 is slightly larger than the length of the lithium battery 100 (the length from the left end to the right end), and then place the lithium battery 100 between the left and right clamping members 121, and then operate the adjusting motor 122 to drive the adjusting screw 123 to rotate in the opposite direction, thereby driving the right clamping member 121 to move to the left along the adjusting screw 123 until the left and right clamping members 121 clamp the lithium battery 100 together. In this way, the distance between the left and right clamping members 121 can be dynamically adjusted, and lithium batteries of different sizes can be firmly clamped. In order to make the right clamp 121 move left and right stably, two guide rails 125 are respectively provided on the front and rear sides of the slide 127 in this embodiment, and the front and rear sides of the bottom of the right clamp 121 are respectively connected to the two guide rails 125 by two guide sliders 126. In this way, when the right clamp 121 is driven by the adjustment motor 122 to move left and right, it can move left and right more stably under the guidance of the guide rails 125. After placing the lithium battery 100, the operator closes the placement window 11. The spraying equipment includes a controller (not shown in the figure) and a control screen 5 connected to the controller. The controller is electrically connected to the battery conveying device, the CCD detection device 2, the three-sided spray curing device 3 and the enhanced curing device 4. The control screen 5 is arranged on the outer side of the CCD detection device 2 for the operator to input control instructions. After the operator installs the lithium battery 100, he inputs instructions through the control screen 5 to start the spraying equipment to execute the insulating film spraying process. After receiving the instructions, the controller executes the following insulating film spraying process:

[0030] The controller controls the conveyor motor to drive the conveyor belt to move rightward, driving the battery carrier 12 on the conveyor belt to move rightward, thereby driving the lithium battery 100 to move rightward to the detection station of the CCD detection device 2. Figure 5As shown, the CCD detection device 2 includes a group of top detection probe groups 21 located at the top and two groups of side detection probe groups 22 located below the top detection probe group 21 and separated on the front and rear sides. One group of top detection probe groups 21 includes 3 probes, and one group of side detection probe groups 22 includes 4 probes. The detection station is located directly below the top detection probe group 21 and between the two groups of side detection probe groups 22. After the lithium battery 100 arrives at the detection station, the controller sends an instruction to notify the CCD detection device 2 to detect the lithium battery 100. The CCD detection device 2 takes pictures of the lithium battery 100 through each group of detection probe groups 21 and 22 to obtain images of the top surface and the front and rear surfaces of the lithium battery 100, and performs image recognition based on the images to obtain the dimensions (length and width) of the top surface and the front and rear surfaces of the lithium battery 100 in the current placement state. In this embodiment, the CCD detection device 2 is used as the image detection device, which is not preferred. Other embodiments can be replaced by other image intelligent recognition devices. The CCD detection device 2 feeds back the measured dimensions of the top surface and the front and rear surfaces of the lithium battery 100 to the controller. After receiving the dimensions of the top surface and the front and rear surfaces of the lithium battery 100 , the controller controls the conveying motor to continue to drive the battery carrier to move rightward, thereby driving the lithium battery 100 to move rightward to the three-sided spray curing device 3 .

[0031] like Figure 6 As shown, the three-sided spraying and curing device 3 includes a top surface spraying module 31, a double side surface spraying module 32 and a pre-curing module 33 arranged from left to right. Figure 7 As shown, it includes a top spray head 311 (i.e., a first spray head) with a group of nozzles facing vertically downward (the nozzles of the top spray head 311 are not shown in the figure due to the viewing angle). Figure 8 As shown, it includes two groups of side nozzles 321 (i.e., second nozzles) separated at the front and rear sides and with nozzles facing each other laterally. The pre-curing module 33 is used as an insulating film curing device, such as Fig. 9 and Fig.10 As shown, it includes a top LED pre-curing light 331 (i.e., the second curing light) and two side LED pre-curing lights 332 (i.e., the first curing lights) located at the front and rear sides, and the top LED pre-curing light 331 is located above the two side LED pre-curing lights 332. Figure 8As shown, the double-side spraying module 32 also includes a bidirectional screw motor 324 as a spacing adjustment mechanism. The bidirectional screw motor 324 includes a motor body 322 and a screw 323 driven to rotate by the motor body. The two groups of side spray heads 321 are respectively connected to the two ends of the screw 323 through sliders. The top spraying module 31 is provided with two rows of top spray heads 311 arranged in a front-to-back direction, and each row has four top spray heads 311. Due to the different types of lithium batteries 100, the widths of the top and rear sides are different. If the front and rear width of the lithium battery 100 is small, only part of the two columns of top spray heads 311 is needed to cover the width of the area to be sprayed on the top surface of the lithium battery 100, for example, only the two top spray heads 311 on the front side of each column of top spray heads 311 are needed; if the front and rear width of the lithium battery 100 is large, more top spray heads 311 are needed to cover the width of the area to be sprayed on the top surface of the lithium battery 100, for example, three top spray heads 311 on the front side of each column of top spray heads 311 are needed. Therefore, the controller first determines the number of top spray heads 311 required to be activated by the top spray module 31 according to the width of the top surface of the lithium battery 100, and then determines the required spacing between the two groups of side spray heads 321 for spraying the front and rear sides of the lithium battery 100 according to the width of the top surface of the lithium battery 100 (i.e. the width of the front and rear sides), and accordingly starts the motor body 322 of the bidirectional screw motor 324 to rotate forward / reverse, and the screw 323 rotates to drive the two groups of side spray heads 321 to move relatively close / relatively away along the screw 323 synchronously until the spacing between the two groups of side spray heads 321 reaches the required spacing. Fig.11 As shown, the pre-curing module 33 is also provided with a bidirectional screw motor 335 like the double-side spraying module 32. The bidirectional screw motor 335 can adjust the distance between the two side LED pre-curing lamps 332 to adapt to lithium batteries 100 of different sizes. Specifically: before the lithium battery 100 is moved to the three-sided spray curing device 3, the controller determines the distance required for the two side LED pre-curing lamps 332 to pre-cure the front and rear sides of the lithium battery 100 according to the width of the top surface of the lithium battery 100 currently facing upward, and accordingly starts the motor body 334 of the bidirectional screw motor 335 to rotate forward / reverse, driving the screw 334 to rotate, thereby driving the two side LED pre-curing lamps 332 to move relatively close / relatively away from each other synchronously along the screw 334 until the distance between the two side LED pre-curing lamps 332 reaches the required distance. The enhanced curing device 4 acts as an insulating film curing device, such as Figures 12-14 As shown, it includes a top surface enhanced curing electrodeless lamp 41 (i.e., the second curing lamp) and two side enhanced curing electrodeless lamps 42 (i.e., the first curing lamp) separated at the front and rear sides. The top surface enhanced curing electrodeless lamp 41 is located above the two side enhanced curing electrodeless lamps 42. Similarly, Fig.15As shown, the enhanced curing device 4 is also provided with a bidirectional screw motor 43 like the double-side spraying module 32. The bidirectional screw motor 43 can adjust the distance between the two side enhanced curing electrodeless lamps 42 to adapt to lithium batteries 100 of different sizes. Specifically: the bidirectional screw motor 43 includes a motor body 431 and a screw 432. The tops of the two side enhanced curing electrodeless lamps 42 are slidably connected to the two ends of the screw 432 through connecting blocks 421 respectively. Before the lithium battery 100 is moved to the three-sided spraying and curing device 3, the controller also determines the distance required for the two side enhanced curing electrodeless lamps 42 to perform enhanced curing on the front and rear sides of the lithium battery 100 according to the width of the current upward top surface of the lithium battery 100. Based on this, the motor body 431 of the bidirectional screw motor 43 is started to rotate forward / reverse, driving the screw 432 to rotate, thereby driving the two side enhanced curing electrodeless lamps 42 to synchronously approach / move relatively closer along the screw 432 until the distance between the two side enhanced curing electrodeless lamps 42 reaches the required distance.

[0032] The right end of the lithium battery 100 moves to the three-sided spray curing device 3, and the controller controls the top surface spraying module 31 to start the corresponding number of top spray heads 311 to spray downwards, and controls the double side spraying module 32 to start the front and rear two groups of side spray heads 321 to spray toward the middle, and turns on the three LED pre-curing lamps of the pre-curing module 33 at the same time. The lithium battery 100 moves from left to right, passing through the top surface spraying module 31, the double side spraying module 32 and the pre-curing module 33 in sequence, to achieve top surface spraying, front and rear double side spraying and pre-curing of these three surfaces, that is, to achieve three-sided spraying and pre-curing. The specific implementation process is as follows: the lithium battery 100 moves from left to right and passes directly below the top surface spraying module 31, and the top spray head 311 sprays downwards. The right end of the lithium battery 100 moves to the top spray head 311 first, so the right end of the top surface of the lithium battery 100 is sprayed first. Insulating paint is applied. In the process of the lithium battery 100 moving from left to right, the top surface of the lithium battery 100 is sprayed with insulating paint from right to left in sequence. When the leftmost end of the lithium battery 100 moves away, the top surface spraying module 31 completes the spraying of the entire top surface of the lithium battery 100; then the lithium battery 100 moves from left to right through the front and rear groups of side spray heads 321 of the double side spraying module 32, the front side spray head 321 sprays the front side of the lithium battery 100 backward, and the rear side spray head 321 sprays the front side of the lithium battery 100 forward. 00 is sprayed on the rear side. Since the right end of the lithium battery 100 is first moved between the two sets of side spray heads 321, the right end of the front and rear sides of the lithium battery 100 is first sprayed with insulating paint. In the process of the lithium battery 100 moving from left to right, the front and rear sides of the lithium battery 100 are sprayed with insulating paint from right to left in sequence. When the leftmost end of the lithium battery 100 moves away from the double-side spraying module 32, the spraying of the front and rear sides of the lithium battery 100 is completed; the lithium battery 100 continues to move to the right and passes through the pre-curing module 3 3. The top surface LED pre-curing lamp 331 irradiates downward to cure the insulating paint on the top surface of the lithium battery 100, the front side LED pre-curing lamp 332 irradiates backward to cure the insulating paint on the front side of the lithium battery 100, and the rear side LED pre-curing lamp 332 irradiates forward to cure the insulating paint on the rear side of the lithium battery 100. In this way, the top surface LED pre-curing lamp 331 and the two side LED pre-curing lamps 332 jointly pre-cure the top surface and the front and rear sides of the lithium battery 100 that have just been sprayed.After the lithium battery 100 has completed three-sided spraying and pre-curing, the controller controls the conveying motor to continue driving the conveyor belt to drive the lithium battery 100 to move right to the enhanced curing device 4 for enhanced curing. Specifically: the top surface enhanced curing electrodeless lamp 41 irradiates downward to cure the insulating paint on the top surface of the lithium battery 100, the front side enhanced curing electrodeless lamp 42 irradiates backward to cure the insulating paint on the front side of the lithium battery 100, and the rear side enhanced curing electrodeless lamp 42 irradiates forward to cure the insulating paint on the rear side of the lithium battery 100. In this way, the top surface enhanced curing electrodeless lamp 41 and the two side enhanced curing electrodeless lamps 42 jointly perform enhanced curing on the three surfaces of the lithium battery 100 that have just completed spraying and pre-curing.

[0033] The battery conveyor drives the lithium battery 100 to move from the battery loading device 1 to the right to the CCD detection device 2, the three-sided spraying and curing device 3, and the enhanced curing device 4 in sequence, which is one round of conveyance. The battery conveyor performs the first round of conveyance on the lithium battery 100 as described above, and only completes the spraying and curing of the three sides of the lithium battery 100 (i.e., the first round of spraying and curing). The rectangular lithium battery 100 has six sides, so the lithium battery 100 needs to be conveyed in the second round for the second round of spraying and curing. The remaining three sides of the lithium battery 100 are sprayed and cured, and the specific process is as follows:

[0034] After the three sides of the lithium battery 100 have completed enhanced curing, that is, after the first round of spraying and curing is completed, the controller controls the conveying motor to drive the conveyor belt to reverse, driving the lithium battery 100 back to the starting point, that is, back to the battery loading device 1. Since the top surface and the front and rear two side surfaces of the lithium battery 100 in the original placement state have completed spraying and curing, the remaining bottom surface and the left and right two side surfaces need to be sprayed and cured. Considering that the positions of the three-sided spraying and curing device 3 and the enhanced curing device 4 are fixed, the lithium battery 100 needs to be turned upside down and rotated horizontally by ninety degrees, so that the orientation of the remaining three surfaces is changed to adapt to the three-sided spraying and curing device 3 and the enhanced curing device 4. To this end, the spraying equipment of this embodiment is provided with a manipulator (not shown in the figure) as a flipping mechanism in the battery loading device 1. After the lithium battery 100 is returned to the battery loading device 1, the controller controls the manipulator to flip the lithium battery 100. Specifically, the manipulator takes out the lithium battery 100 from the battery carrier, turns the lithium battery 100 upside down and rotates it horizontally by ninety degrees, and then reloads it into the battery carrier. Not preferably, other embodiments can be changed to an operator replacing the manipulator as a flipping mechanism, reaching into the placement window 11, and manually flipping the lithium battery 100. After the lithium battery 100 is flipped, its original bottom surface is switched to the top surface, and the original left and right sides are switched to the front and back sides. In this state, the controller controls the conveying motor to drive the conveyor belt for the second round of transmission. The second round of transmission process is consistent with the first round of transmission process, and will not be repeated. The specific process is referred to above. After completing the second round of spraying and curing, the controller controls the conveying motor to drive the conveyor belt to reverse, driving the lithium battery 100 that has completed six-sided spraying and curing to return to the battery loading device 1. The operator opens the placement window 11 and then takes out the lithium battery 100 that has completed spraying and curing from the battery carrier. The battery insulation film spraying equipment provided in this embodiment can perform three-sided spraying and curing in each round, and only needs to perform two rounds, each round performs two spraying and two curing, and only needs to perform four spraying and four curing in total to complete six-sided spraying and curing, which is highly efficient, and the equipment structure is simple and the manufacturing cost is low. In addition, the spraying equipment is provided with a spacing adjustment mechanism to adjust the spacing between the two groups of side nozzles 321, which can adapt to batteries of different sizes.

[0035] In this embodiment, the top surface spraying module 31 for spraying from top to bottom is used as the first spraying module (or single-sided spraying module), and the double-sided spraying module 32 for spraying from front to back is used as the second spraying module (or double-sided spraying module). In other embodiments, the first spraying module (or single-sided spraying module) is changed to a bottom surface spraying module for spraying from bottom to top, and the second spraying module (or double-sided spraying module) is changed to a double-sided spraying module for spraying from left to right. Correspondingly: one of the three LED pre-curing lamps of the pre-curing module 33 is set below the lithium battery moving route as the bottom surface LED pre-curing lamp, and the other two are separated on the left and right sides as the side LED pre-curing lamps; one of the three electrodeless lamps of the enhanced curing device is set below the lithium battery moving route as the bottom surface enhanced curing lamp, and the other two are separated on the left and right sides as the side enhanced curing lamps; the battery conveying device is changed to inverted; the double-sided spraying module, the pre-curing module, and the enhanced curing device are all changed to be vertically movable to avoid the battery conveying route. In this way, the same technical effect as that of the present embodiment can be achieved. In addition, in the present embodiment, the double side spraying module 32 is arranged on the right side of the top surface spraying module 31, and the top surface spraying module 31 and the double side spraying module 32 correspond to different spraying stations respectively, so that the lithium battery 100 is first moved to the top surface spraying station for top surface spraying, and then moved to the double side spraying station for double side spraying. Other embodiments can be changed to merge the spraying stations of the top surface spraying module 31 and the double side spraying module 32 together, that is, the two side spray heads 321 of the double side spraying module 32 are arranged on both sides directly below the top surface spraying module 31, and the above two are located in the same vertical plane, so that the lithium battery 100 can be simultaneously sprayed on the top surface and sprayed on the double sides at one station.

[0036] This embodiment realizes six-sided spraying of the lithium battery 100 by using two rounds of CCD detection device 2, three-sided spraying and curing device 3 and enhanced curing device 4. The non-preferred embodiment can be changed to set one more set of CCD detection device 2, three-sided spraying and curing device 3 and enhanced curing device 4, and the manipulator as the flipping mechanism is changed to be set in the two sets of devices. The controller controls the battery conveying device to drive the lithium battery 100 to move through the first set of CCD detection device 2, three-sided spraying and curing device 3 and enhanced curing device 4, and after spraying and curing three of the surfaces of the lithium battery 100, the controller controls the manipulator to turn the lithium battery upside down and rotate it horizontally by ninety degrees, and then controls the battery conveying device to continue to drive the lithium battery 100 to move through the second set of CCD detection device 2, three-sided spraying and curing device 3 and enhanced curing device 4, and spraying and curing the remaining three surfaces of the lithium battery 100.

[0037] Considering that the spraying module may fail after a period of use, in order to facilitate maintenance, the top spraying module 31 and the double side spraying module 32 are designed as detachable independent modules in this embodiment. Figure 7As shown, a group of sliders are respectively provided on the left and right sides of the top of the top surface spraying module 31, and each group of sliders includes three sliders 312 ( Figure 7 Only the three sliders 312 of the left slider group are shown, and the sliders on the right are not shown due to the viewing angle. The spraying equipment is provided with two slide rails 313 corresponding to the left and right slider groups above the top spraying module. The two slide rails 313 and the two slider groups serve as sliding mechanisms. The slider 312 of the slider group on the left side of the top of the top spraying module 31 is installed on the slide rail 313 on the left, and the slider 312 of the slider group on the right side of the top surface of the top spraying module 31 is installed on the slide rail 313 on the right. The top spraying module 31 can slide along the slide rail 313 through the slider 312. A handle 314 is provided on the front side panel of the top spraying module 31. If the user needs to repair the top spraying module 31, he / she just holds the handle 314 on the front side panel of the top spraying module 31 and pulls it outward, so that the top spraying module 31 slides along the slide rail 313 and moves out of the spraying equipment for easy maintenance. The same is true for the double-side spraying module 32. Figure 8 As shown, there is a group of sliders on the left and right sides of the top, each of which includes three sliders 325 ( Figure 8 Only three sliders 325 of the left slider group are shown in the figure, and the sliders on the right side are not shown due to the viewing angle. The spraying equipment is provided with two slide rails 326 corresponding to the left and right slider groups respectively above the double-side spraying module 32. The two slide rails 326 and the two slider groups serve as sliding mechanisms. The slider 325 of the slider group on the left side of the top of the double-side spraying module 32 is mounted on the left slide rail 326, and the slider 325 of the slider group on the right side of the top of the double-side spraying module 32 is mounted on the right slide rail 326. The double-side spraying module 32 can slide along the slide rail 326 through the slider 325. A handle 327 is provided on the front side panel of the double-side spraying module 32. If the user needs to repair the double-side spraying module 32, he / she can hold the handle 327 of the front side panel of the double-side spraying module 31 and pull it outward, so that the double-side spraying module 32 slides along the slide rail 326 and moves out of the spraying equipment, which is convenient for maintenance.

[0038] Considering that the insulating film formed by spraying of the lithium battery 100 may not meet the standards, for example, some areas may not be sprayed, the insulating film thickness may not be enough, etc., in this embodiment, preferably, Figure 1 As shown, a CCD detection device 6 (not shown, hereinafter referred to as the second CCD detection device) is added between the three-side spray curing device 3 and the enhanced curing device 4. The second CCD detection device 6 has the same structure as the CCD detection device 2 mentioned above. Please refer to Figure 5, the second CCD detection device 6 includes a group of top detection probes and a group of side detection probes distributed on the front and rear sides, and the top detection probe group is located above the two groups of side detection probes. After three of the surfaces of the lithium battery 100 have been sprayed and pre-cured, the controller controls the conveyor motor to drive the conveyor belt to move rightward, driving the lithium battery 100 to continue to move rightward to the second CCD detection device 6. The second CCD detection device 6 takes pictures of the three surfaces of the lithium battery 100 that have been sprayed and pre-cured through the top detection probe group and the side detection probe group, and detects whether the insulating film sprayed on these three surfaces of the lithium battery 100 meets the standards. If not, the controller controls the conveyor motor to drive the conveyor belt to retreat, driving the lithium battery 100 back to the battery loading device 1, and the operator takes out the lithium battery from the placement window 11 for defective processing. If the insulating film sprayed on these three surfaces of the lithium battery 100 meets the standards, the controller controls the conveyor motor to drive the conveyor belt to continue to move rightward, driving the lithium battery 100 to move to the enhanced curing device 4 for enhanced curing. Other embodiments Preferably, when it is determined that the three surfaces of the lithium battery 100 that have been sprayed and pre-cured do not meet the standards, the lithium battery 100 is not driven back to the battery loading device 1, but is instead driven back to the three-side spraying and curing device 3 for supplementary spraying (secondary spraying). After the supplementary spraying is completed, the controller controls the conveying motor to drive the conveyor belt to move right, driving the lithium battery 100 to continue to move right to the second CCD detection device. The second CCD detection device uses the detection probe to take pictures of the three surfaces of the lithium battery 100 that have been sprayed and pre-cured again. If the insulating film formed by the spraying of the three surfaces of the lithium battery 100 meets the standards, then the controller controls the conveying motor to drive the conveyor belt to continue to move right, driving the lithium battery 100 to move to the enhanced curing device 4 for enhanced curing.
