Abstract
Description
Technical Field
[0001] This utility model relates to capacitor manufacturing equipment, and more particularly to a coating mechanism for capacitor production. Background Technology
[0002] The capacitor core is formed by layering and winding an anode foil strip, electrolytic paper, and a cathode foil strip. To improve the bonding strength of the lamination and winding, it is generally necessary to coat the surface of at least one of the anode foil strip, electrolytic paper, and cathode foil strip with adhesive.
[0003] Existing glue-applying mechanisms only have a single glue-applying wheel, and use a glue-dispensing conduit to directly apply glue to the surface of the wheel. The glue distribution on the wheel is uneven, and it is impossible to spread the glue evenly, which easily leads to uneven material feeding and affects the glue-applying quality. Utility Model Content
[0004] To address the shortcomings of the prior art, this invention provides a coating mechanism for capacitor production, which can improve coating uniformity.
[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:
[0006] A coating mechanism for capacitor production includes:
[0007] Glue applicator;
[0008] A glue container is provided on the glue applicator and is used to hold glue.
[0009] A glue-applying roller is mounted on the glue-applying frame, with part of its circumference inside the glue-holding box and part of its circumference outside the glue-holding box.
[0010] The first glue-applying roller is disposed on the glue-applying frame, and its circumference abuts against the circumference of the glue-applying roller located outside the glue-holding box;
[0011] The second glue-applying wheel is disposed on the glue-applying frame and is disposed opposite to the first glue-applying wheel;
[0012] A glue-applying drive mechanism is disposed on the glue-applying frame and is connected to drive the glue-applying wheel, the first glue-applying wheel and the second glue-applying wheel to rotate. The glue-applying wheel and the first glue-applying wheel rotate in opposite directions, and the first glue-applying wheel and the second glue-applying wheel rotate in opposite directions.
[0013] Furthermore, there is a gap between the circumference of the first coating wheel and the circumference of the second coating wheel.
[0014] Furthermore, the circumference of the first coating wheel abuts against the circumference of the second coating wheel.
[0015] Furthermore, the glue application drive mechanism includes a glue application motor, a drive gear, a glue application gear, a first glue application gear, a second glue application gear, and a transmission belt. The drive gear is coaxially connected to the output shaft of the glue application motor, the glue application gear is coaxially connected to the glue application wheel, the first glue application gear is coaxially connected to the first glue application wheel, and the second glue application gear is coaxially connected to the second glue application wheel. The glue application motor is connected to the drive gear, the glue application gear, the first glue application gear, and the second glue application gear via the transmission belt.
[0016] Furthermore, the glue application drive mechanism also includes a glue application rotating shaft, a first glue application rotating shaft, and a second glue application rotating shaft, all of which are rotatably mounted on both sides of the glue application frame. One end of each of the glue application rotating shafts, the first glue application rotating shaft, and the second glue application rotating shaft on the first side of the glue application frame is coaxially and fixedly connected to the glue application wheel, the first glue application wheel, and the second glue application wheel, respectively, and the other end of each of the glue application rotating shafts on the second side of the glue application frame is coaxially and fixedly connected to the glue application gear, the first glue application gear, and the second glue application gear, respectively. The glue application motor is located on the second side of the glue application frame.
[0017] Furthermore, both the inner and outer surfaces of the transmission belt have transmission teeth. The transmission teeth on the inner surface mesh with the drive gear, the glue-applying gear, and the second glue-applying gear, while the transmission teeth on the outer surface mesh with the first glue-applying gear.
[0018] Furthermore, the glue application mechanism also includes a glue application scraper, which is disposed on the glue application frame and corresponds to the glue application wheel; the glue application scraper includes a scraping groove, and the circumference of the glue application wheel extends into the scraping groove of the glue application scraper.
[0019] Furthermore, the glue application mechanism also includes a first glue application scraper, which is disposed on the glue application frame and corresponds to the first glue application wheel; the first glue application scraper includes a scraping groove, and the circumference of the first glue application wheel extends into the scraping groove of the first glue application scraper.
[0020] Furthermore, the glue application mechanism also includes a second glue application scraper, which is disposed on the glue application frame and corresponds to the second glue application wheel; the second glue application scraper includes a scraping groove, and the circumference of the second glue application wheel extends into the scraping groove of the second glue application scraper.
[0021] Furthermore, the glue application mechanism also includes a translation drive mechanism, which drives the glue application frame to translate.
[0022] This invention has the following beneficial effects: The glue-applying mechanism of this invention utilizes the glue-applying wheel to apply glue to the glue-receiving wheel. The glue-applying wheel is located on a portion of the circumference inside the glue-receiving box, where it can pick up the glue contained in the glue-receiving box and carry the picked-up glue away from the glue-receiving box through rotation. The glue-applying wheel is located on a portion of the circumference outside the glue-receiving box, where it can abut against the circumference of the first glue-applying wheel to apply the picked-up glue to the circumference of the first glue-applying wheel. As the number of rotations increases, the glue on the first glue-applying wheel can be distributed more evenly under the centrifugal force and the friction of the glue-applying wheel. During glue application, the material to be glued is fed between the first glue-applying wheel and the second glue-applying wheel, so that the second glue-applying wheel presses the material to be glued against the first glue-applying wheel, allowing the glue on the first glue-applying wheel to be evenly applied to the material to be glued, thereby improving the uniformity of glue application.

[0030] Example 1
[0031] like Figure 1 As shown, a coating mechanism for capacitor production includes:
[0032] Glue applicator 1;
[0033] The glue container 2 is disposed on the glue applicator 1 and is used to hold glue.
[0034] The glue-applying roller 3 is mounted on the glue-applying frame 1, with part of its circumference inside the glue-holding box 2 and part of its circumference outside the glue-holding box 2.
[0035] The first glue-applying roller 4 is disposed on the glue-applying frame 1, and its circumference abuts against the circumference of the glue-applying roller 3 located outside the glue-holding box 2;
[0036] The second glue-applying wheel 5 is disposed on the glue-applying frame 1 and is disposed opposite to the first glue-applying wheel 4;
[0037] The glue application drive mechanism 6 is disposed on the glue application frame 1 and is connected to drive the glue application wheel 3, the first glue application wheel 4 and the second glue application wheel 5 to rotate. The glue application wheel 3 and the first glue application wheel 4 rotate in opposite directions, and the first glue application wheel 4 and the second glue application wheel 5 rotate in opposite directions.
[0038] The gluing mechanism of this invention utilizes the gluing roller 3 to apply glue to the glue container 2. The gluing roller 3 is located on a portion of the circumference inside the glue container 2, where it can pick up the glue contained in the container 2 and rotate to carry the picked-up glue away from the container 2. The gluing roller 3 is located on a portion of the circumference outside the container 2, where it can abut against the circumference of the first gluing roller 4 to apply the picked-up glue to the circumference of the first gluing roller 4. As the number of rotations increases, the glue on the first gluing roller 4 can be distributed more evenly under the centrifugal force and the friction of the gluing roller 3. During gluing, the material to be coated is fed between the first gluing roller 4 and the second gluing roller 5, so that the second gluing roller 5 presses the material to be coated against the first gluing roller 4, allowing the glue on the first gluing roller 4 to be evenly coated onto the material to be coated, thereby improving the uniformity of gluing.
[0039] If the glue-applying mechanism only needs to apply glue to one side of the strip to be coated, there is a gap between the circumference of the first glue-applying wheel 4 and the circumference of the second glue-applying wheel 5, and the size of the gap is adapted to the thickness of the strip to be coated.
[0040] If the gluing mechanism needs to apply glue to both sides of the strip to be coated simultaneously, the circumference of the first gluing wheel 4 and the circumference of the second gluing wheel 5 abut against each other, so that during the gluing stage, the glue on the circumference of the first gluing wheel 4 can be applied to the circumference of the second gluing wheel 5. During the gluing stage, the second gluing wheel 5 applies the glue on its circumference to the other surface of the strip to be coated by rolling the strip.
[0041] Preferably, the glue application mechanism further includes a glue application scraper 7, which is disposed on the glue application frame 1 and corresponds to the glue application wheel 3; the glue application scraper 7 includes a scraping groove, and the circumference of the glue application wheel 3 extends into the scraping groove of the glue application scraper 7.
[0042] The glue scraper 7 is used to smooth the glue on the circumference of the glue roller 3. At the same time, through the groove design, the glue scraper plates located on both sides of the glue scraping groove remove the residual glue on the inner and outer sides of the glue roller 3.
[0043] Preferably, the glue application mechanism further includes a first glue application scraper 8, which is disposed on the glue application frame 1 and corresponds to the first glue application wheel 4; the first glue application scraper 8 includes a scraping groove, and the circumference of the first glue application wheel 4 extends into the scraping groove of the first glue application scraper 8.
[0044] The first glue-applying scraper 8 is used to smooth the glue on the circumference of the first glue-applying wheel 4. At the same time, through the groove design, the scraper plates located on both sides of the scraper groove remove the residual glue on the inner and outer sides of the first glue-applying wheel 4.
[0045] If the coating mechanism needs to coat both sides of the strip to be coated with adhesive at the same time, the coating mechanism further includes a second coating scraper 9, which is disposed on the coating frame 1 and corresponds to the second coating wheel 5; the second coating scraper 9 includes a scraping groove, and the circumference of the second coating wheel 5 extends into the scraping groove of the second coating scraper 9.
[0046] Similarly, the second glue-applying scraper 9 is used to smooth the glue on the circumference of the second glue-applying wheel 5, and at the same time, through the groove design, the scraper plates located on both sides of the scraper groove remove the residual glue on the inner and outer sides of the second glue-applying wheel 5.
[0047] like Figure 2 As shown, the glue application drive mechanism 6 includes a glue application motor 61, a drive gear 62, a glue application gear 63, a first glue application gear 64, a second glue application gear 65, and a transmission belt 66. The drive gear 62 is coaxially connected to the output shaft of the glue application motor 61, the glue application gear 63 is coaxially connected to the glue application wheel 3, the first glue application gear 64 is coaxially connected to the first glue application wheel 4, and the second glue application gear 65 is coaxially connected to the second glue application wheel 5. The glue application motor 61 is connected to the drive gear 62, the glue application gear 63, the first glue application gear 64, and the second glue application gear 65 via the transmission belt 66.
[0048] In this embodiment, the glue application drive mechanism 6 further includes a glue application rotating shaft 67, a first glue application rotating shaft 68, and a second glue application rotating shaft 69. The glue application rotating shaft 67, the first glue application rotating shaft 68, and the second glue application rotating shaft 69 are rotatably disposed on both sides of the glue application frame 1. One end of the glue application rotating shaft 67, the first glue application rotating shaft 68, and the second glue application rotating shaft 69 on the first side of the glue application frame 1 is coaxially and fixedly connected to the glue application wheel 3, the first glue application wheel 4, and the second glue application wheel 5, respectively. The other end of the glue application rotating shaft 67 on the second side of the glue application frame 1 is coaxially and fixedly connected to the glue application gear 63, the first glue application gear 64, and the second glue application gear 65, respectively. The glue application motor 61 is disposed on the second side of the glue application frame 1.
[0049] The inner and outer surfaces of the transmission belt 66 are both equipped with transmission teeth. The transmission teeth on the inner surface mesh with the drive gear 62, the glue-applying gear 63, and the second glue-applying gear 65, while the transmission teeth on the outer surface mesh with the first glue-applying gear 64.
[0050] Example 2
[0051] As an optimization of Embodiment 1, in this embodiment, such as Figure 3 As shown, the glue application mechanism also includes a translation drive mechanism 10, which drives the glue application frame 1 to translate.
[0052] Preferably, the translation drive mechanism 10 is parallel to the feeding direction of the adhesive strip to be coated, so as to assist in the coating by driving the gluing wheel 3, the first gluing wheel 4 and the second gluing wheel 5 to translate relative to the adhesive strip along the feeding direction.
[0053] The translation drive mechanism 10 includes a translation motor 101, a lead screw guide rail 102, and a translation mounting base 103. The translation mounting base 103 is movably mounted on the lead screw guide rail 102. The translation motor 101 drives the threaded lead screw in the lead screw guide rail 102 to rotate, and then drives the translation mounting base 103 to translate on the lead screw guide rail 102 through the nut on the threaded lead screw. The glue applicator 1 is mounted and fixed on the translation mounting base 103.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
