[0027] like Figure 1-2 and Figure 6-8 As shown:

[0028] A battery manufacturing device includes a fixed frame 101 and a fixed part 201, a slide seat 102 is slidably connected to the fixed frame 101, an addition box 103 is fixedly connected to the slide seat 102, a nozzle is provided on the lower side of the addition box 103, a slide rod 301 is slidably connected to the fixed part 201, a triangular plate 302 is fixedly connected to the slide rod 301, a first compression spring is fixedly connected between the slide rod 301 and the fixed part 201, a first motor is fixedly connected to the fixed frame 101, a first lead screw is fixedly connected to the output shaft of the first motor, and the first lead screw is threadedly connected to the slide seat 102. When in use, the fixed frame 101 and the fixed part 201 are connected to a cylinder that can push the fixed frame 101 and the fixed part 201 to slide downward by tightening bolts, and a hose that can pass slurry is connected to the addition box 103, and the hose can deliver the slurry into the addition box 103.

[0029] By adjusting the telescopic rod of the cylinder, the fixed frame 101 and the fixed part 201 are moved to a suitable height, and the triangular plate 302 is moved to a position that can just contact the thickness of the substrate after coating, so that the substrate passes the lower side of the device from right to left at a uniform speed. During the movement of the substrate, different slurries are introduced into the adding box 103, and the slurry falls through the nozzle on the lower side of the adding box 103, and then falls on the moving substrate. During the movement of the substrate, the slide 102 slides back and forth on the fixed frame 101, so that multiple serrated slurry strips are dripped on the substrate. When the slurry strips move to the lower side of the triangular plate 302, they are moved along with the substrate. As the triangle plate 302 continues to move, it will scrape the serrated slurry belt, so that the slurry belt is evenly coated on the upper surface of the substrate, thereby achieving a uniform coating effect of the slurry. Due to the shape of the triangle plate 302, the excess slurry above the height to be coated will be automatically guided to both sides of the substrate by the triangle plate 302. The staff can place open containers on both sides of the substrate to collect the excess slurry, and then perform subsequent drying and curing operations on the coated substrate to achieve the coating effect. While being able to complete the efficient and uniform coating operation, the excess slurry can be automatically collected, which brings convenience to actual use.

[0030] In the actual coating process, if the substrate surface forms an abnormal protrusion due to insufficient forming effect, when the protrusion passes the position of the triangular plate 302, the triangular plate 302 that was originally used to scrape the coating will be pushed up, and then the forming effect of the substrate can be checked by monitoring the sliding condition of the slide bar 301, which further brings convenience to actual use;

[0031] A displacement sensor A can be connected to the fixed part 201 by tightening bolts on the fixed part 201, and the moving end of the displacement sensor is fixedly connected to the sliding rod 301. When the sliding rod 301 slides, the displacement sensor A receives the signal and converts the signal into an electrical signal for transmission, thereby completing the monitoring effect of the sliding condition of the sliding rod 301.

[0032] like Figure 6-8 As shown:

[0033] It also includes a matching frame 202 slidably connected to the fixed part 201 , an auxiliary rod 104 is connected to the slide seat 102 , the auxiliary rod 104 can contact the matching frame 202 , and a second compression spring is fixed between the matching frame 202 and the fixed part 201 .

[0034] The second compression spring forces the cooperating frame 202 to always press the upper side of the cooperating frame 202 against the auxiliary rod 104. In actual use, when the slide 102 slides left and right on the fixed frame 101, thereby leaving a serrated slurry strip on the substrate, the auxiliary rod 104 will always move synchronously with the fixed frame 101. Due to the shape of the cooperating frame 202, when the slide 102 moves, the cooperating frame 202 will overcome the elastic force of the second compression spring and slide adaptively on the fixed portion 201. By monitoring whether the cooperating frame 202 slides normally, it is possible to check whether the slide 102 slides normally on the fixed frame 101. In the actual operation of the equipment, when the power source driving the slide 102 to slide fails, the situation can be discovered in time, and the power source driving the slide 102 to slide can be repaired in time, thereby ensuring efficient and uniform subsequent coating.

[0035] A displacement sensor B can be connected to the fixed part 201 by tightening bolts on the fixed part 201. The moving end of the displacement sensor B is fixedly connected to the matching frame 202. When the matching frame 202 slides, the moving end of the displacement sensor can move accordingly, and then convert the situation into an electrical signal for transmission, thereby completing the monitoring effect of the matching frame 202.

[0036] like Figure 4 , Figure 5 and Figure 8 As shown:

[0037] It also includes a transverse rod 401 slidably connected to the slide rod 301, two sliding parts 402 are slidably connected to the transverse rod 401, each sliding part 402 is slidably connected to a connecting rod 404, each connecting rod 404 is connected to a scraper 405, a first electric push rod that can push the transverse rod 401 to slide is fixedly connected to the slide rod 301, and a third compression spring is fixedly connected between each sliding part 402 and the connecting rod 404.

[0038] In actual use, the transverse rod 401 can be operated regularly to slide in the direction of the slide rod 301 until both scrapers 405 are against the triangular plate 302, and then the two sliding parts 402 are operated to slide on the transverse rod 401 successively, and then the two scrapers 405 are used to scrape the surface of the triangular plate 302, so that the accumulated excessive slurry is uniformly scraped into the open containers on both sides, so as to avoid the slurry blocking each other and failing to automatically enter the container for storage;

[0039] The two third compression springs are provided so that during the scraping operation, the two connecting rods 404 can be subjected to the elastic force of the two third compression springs so that the two scraping plates 405 always rest against the triangular plate 302 for scraping, thereby ensuring the scraping effect.

[0040] like Figure 6-8 As shown:

[0041] The auxiliary rod 104 is slidably connected to the slide seat 102 , and a second electric push rod capable of pushing the auxiliary rod 104 to slide is fixedly connected to the slide seat 102 . A fourth compression spring is fixedly connected between each sliding portion 402 and the transverse rod 401 .

[0042] When it is necessary to use two scrapers 405 to complete the active scraping operation of excess slurry, the auxiliary rod 104 can be operated to slide between the two connecting rods 404, and then the slide 102 can be operated normally to slide, and then the auxiliary rod 104 can be used to move one of the two connecting rods 404 to complete the subsequent active scraping operation, and then the slide 102 can be operated to slide in the opposite direction to actively scrape the other side. The two fourth compression springs can enable the two sliding parts 402 to actively reset to the initial position after scraping, which is convenient for multiple scraping operations.

[0043] like Figure 5 As shown:

[0044] Each of the connecting rods 404 is fixedly connected with an inclined plate 403 .

[0045] The setting of the two oblique plates 403 ensures that when it is necessary to drive the two connecting rods 404 to slide and then slide the auxiliary rod 104, the auxiliary rod 104 will contact the two connecting rods 404, thereby being smoothly inserted between the two oblique plates 403, and then sliding the slide seat 102 to successfully complete the subsequent active movement of the scraper 405 to perform the scraping operation.

[0046] like Figure 5 As shown:

[0047] The two scrapers 405 are detachably connected to the two connecting rods 404 via bolts.

[0048] In actual use, when the device is in an idle state, the two scrapers 405 can be removed for cleaning or replacement by loosening the bolts, thereby maintaining the cleanliness of the two scrapers 405 for a long time, bringing convenience for subsequent long-term use.

[0049] like Figure 6 As shown:

[0050] A plurality of transmission arc blocks 203 are fixedly connected to the matching frame 202, and the vertical heights of the plurality of transmission arc blocks 203 gradually increase from the middle to both sides.

[0051] When the slide 102 slides, the auxiliary rod 104 passes through the positions of the multiple transmission arc blocks 203, which causes the matching frame 202 to slide downward for a distance. When the auxiliary rod 104 completely passes through the transmission arc block 203, the matching frame 202 is quickly slid upward and reset by the elastic force of the second compression spring, so that when the slide 102 slides, the matching frame 202 can slide up and down on the fixed part 201 for multiple times with gradually increasing sliding amplitudes, which further facilitates the accurate measurement of whether the slide 102 is in a normal sliding state through the displacement sensor B, and further ensures the accuracy of the inspection result;

[0052] When the auxiliary rod 104 needs to slide from both sides of the matching frame 202 to the center of the matching frame 202, the auxiliary rod 104 is slid on the adding box 103 until the auxiliary rod 104 and the multiple transmission arc blocks 203 are staggered, and then the slide 102 is slid to avoid interference.

[0053] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown:

[0054] The fixed part 201 is slidably connected with the telescopic part 204, the triangular plate 302 is fixedly connected with the knocking plate 303, the fixed part 201 is fixedly connected with a third electric push rod capable of pushing the telescopic part 204 to slide, and the fixed part 201 is fixedly connected with an electromagnetic block capable of adsorbing and fixing the sliding rod 301.

[0055] The electromagnetic block is started, and then the electromagnetic block is used to adsorb and fix the slide bar 301. Then, when the two scrapers 405 are used to actively scrape the surface of the triangular plate 302, the telescopic part 204 can be slid to a position where it can contact the knocking plate 303. At this time, the elastic force of the second compression spring on the matching frame 202 will press the telescopic part 204 against the knocking plate 303. Then, the slide 102 is operated to slide. At this time, when the slide 102 passes through the positions of multiple transmission arc blocks 203 in sequence, the matching frame 202 will slide up and down on the fixed part 201 for multiple times, and then the telescopic part 204 is used to knock the knocking plate 303 for multiple times, so that the triangular plate 302 vibrates as a whole for multiple times, so as to facilitate the slurry adhering to the triangular plate 302 to be shaken off, and the shaken slurry is stored in the open container, so as to ensure the long-term scraping effect of the triangular plate 302.

[0056] The plurality of transmission arc blocks 203 whose vertical heights gradually increase from the middle to both sides can ensure that the auxiliary rod 104 can always contact with the transmission arc block 203 and achieve the toggling effect, thereby ensuring that subsequent processing operations proceed normally.

[0057] A battery manufacturing process, using the battery manufacturing equipment:

[0058] Step 1, by adjusting the telescopic rod of the cylinder to move, the fixing frame 101 and the fixing part 201 move;

[0059] Step 2: Make the substrate pass through the lower side of the device from right to left at a uniform speed, and inject the homogenized slurry into the adding box 103;

[0060] Step 3, operating the slide 102 to slide back and forth on the fixed frame 101, and making the slurry fall continuously from the nozzle;

[0061] Step 4: placing open containers on both sides of the substrate to collect excess slurry;

[0062] Step 5, regularly operate the auxiliary rod 104 to slide on the slide seat 102 until the auxiliary rod 104 is inserted between the two connecting rods 404;

[0063] Step 6: Slide the two connecting rods 404 in sequence, and use the scraper 405 to complete the scraping operation on the triangular plate 302;

[0064] Step seven, the coated substrate is subsequently dried, rolled, slit, baked, wound, shelled, injected and sealed to form a finished battery.

[0065] A battery, the magnetic material comprises the following raw materials in parts by weight: 45 parts of lithium cobalt oxide, 25 parts of natural graphite and 23 parts of organic electrolyte.
