Description

Technical Field

[0001] The utility model relates to the technical field of electronic manufacturing, in particular to a BMU protection plate dispensing control and adjustment device. Background Art

[0002] In the battery manufacturing process, dispensing is an important step, which involves precisely applying glue or other adhesive materials to the designated position of the BMU protective plate to achieve the purpose of fixing, sealing or insulating between components.

[0003] During the glue dispensing process, after the BMU protection board leaves the glue dispenser, a thin line of glue forms at the end of the dispenser tube, the so-called "tailing". Due to glue tailing, the glue that should have been confined to the designated location will exceed the predetermined boundary, resulting in glue appearing in non-designated areas of the BMU protection board, forming glue overflow. This glue overflow may not only affect the appearance quality of the BMU protection board, but also have potential impacts on its performance and safety. Utility Model Content

[0004] The purpose of the present invention is to provide a BMU protection plate dispensing control and adjustment device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides a BMU protection plate dispensing control and adjustment device, including a dispensing device, a glue dripping tube and a BMU protection plate. A dust cleaning and anti-overflow glue component is arranged above the dispensing device. The dust cleaning and anti-overflow glue component includes a slide plate installed on the outer wall of the glue dripping tube. The slide plate is threadedly connected to a screw rod. A plurality of fan blades are installed at the bottom end of the screw rod. The outer wall of the screw rod is threadedly connected to a bracket. A protective frame is installed at one end of the bracket.

[0006] Furthermore, a gantry is installed on the top of the dispensing device, the screw rod is rotatably connected to the gantry, and the fan blades and the bracket are both located below the gantry.

[0007] Furthermore, the protective frame is hinged with a baffle, and an elastic rope is connected between the baffle and the gantry. The end of the elastic rope away from the gantry is located on the side of the baffle away from the protective frame. A connecting rod is installed on the outer wall of the protective frame, and a plurality of torsion springs are connected to the outer wall of the connecting rod. The torsion springs and the connecting rod are both located at the connection between the protective frame and the baffle.

[0008] Furthermore, an absorption pad is provided inside the baffle, and a plurality of through holes are opened on one side of the baffle, and the through holes correspond to the inside of the protective frame.

[0009] Furthermore, the baffle is provided with a cavity, the absorption pad is located inside the cavity, and the absorption pad is slidably connected to the inner wall of the cavity.

[0010] Furthermore, two L-shaped fixing rods are installed on the outer wall of the protective frame, a support rod is provided on one side of the protective frame, and one end of the L-shaped fixing rod away from the protective frame is connected to the outer wall of the support rod, and the outer wall of the elastic rope is against the outer wall of the support rod.

[0011] Furthermore, circular blocking plates are installed at both ends of the support rod, and the elastic rope is located between the two circular blocking plates.

[0012] Furthermore, a support rod is installed on the inner top wall of the gantry, and the bracket is slidably connected to the outer wall of the support rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the present invention, when the glue dripping tube moves downward for glue dispensing, it drives the slide plate to slide along the screw rod. The rotation of the screw rod drives the fan blades to rotate and blow off the dust on the surface of the BMU protection plate to ensure the accuracy of glue dispensing. At the same time, the bracket and the protective frame slide down with the rotation of the screw rod. The protective frame covers the glue dispensing area to avoid glue tailing and ensure that the glue is accurately applied to the predetermined position.

[0015] 2. In the present invention, when the protective frame moves downward, the elastic rope pulls the baffle away from its bottom. When the protective frame moves upward, the torsion spring bounces the baffle back to its original position, blocking the bottom of the protective frame and preventing the glue on the inner wall from flowing onto the BMU protection plate. In this way, the baffle effectively prevents the unexpected flow of glue and improves the accuracy of glue dispensing. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6 , the utility model provides a technical solution:

[0027] See Figures 1-6 As shown, a BMU protection plate dispensing control and adjustment device includes a dispensing device 1, a glue dripping tube 3 and a BMU protection plate 4. The BMU protection plate 4 is located below the glue dripping tube 3. A dust cleaning and anti-overflow glue component 2 is provided above the dispensing device 1. The dust cleaning and anti-overflow glue component 2 includes a slide plate 201 fixedly installed on the outer wall of the glue dripping tube 3. The slide plate 201 is threadedly connected to a screw rod 202. A plurality of fan blades 203 are fixedly installed on the bottom end of the screw rod 202. The outer wall of the screw rod 202 is threadedly connected to a bracket 204. A protective frame 205 is fixedly installed on the end of the bracket 204 away from the screw rod 202. The protective frame 205 is located directly below the glue dripping tube 3.

[0028] In the prior art, the BMU protection plate 4 is first transferred to the bottom of the glue dripping tube 3 by the transmission structure on the glue dispensing device 1. The glue dripping tube 3 in the glue dispensing device 1 moves downward when dispensing glue on the BMU protection plate 4 until the glue outlet at the bottom of the glue dripping tube 3 is close to the top of the BMU protection plate 4. Then, the glue in the glue dripping tube 3 can drip from the bottom end of the glue dripping tube 3 to a specific area on the top of the BMU protection plate 4. When the glue dripping tube 3 moves downward, it drives the slide 201 to slide along the screw rod 202.

[0029] Since the connection between the slide plate 201 and the screw rod 202 is provided with a thread, and the thread inside the slide plate 201 is adapted to the screw rod 202, the screw rod 202 will rotate when the slide plate 201 moves downward along the outer wall of the screw rod 202. After the screw rod 202 rotates, it drives the fan blades 203 to rotate. The wind generated by the rotation of the fan blades 203 will blow the surface of the BMU protection plate 4, blowing off the dust on the surface of the BMU protection plate 4. The presence of dust particles will interfere with the accuracy of glue dispensing, resulting in uneven glue distribution or offset of the glue dispensing position. The fan blades 203 blowing off the dust can eliminate this interference, ensuring that the glue can be accurately applied to the predetermined position on the top of the BMU protection plate 4.

[0030] As the screw rod 202 rotates, the bracket 204 will also slide downward along the outer wall of the screw rod 202 until the bottom of the protective frame 205 is close to the top of the BMU protection plate 4. Then the glue dripping tube 3 drips glue to the BMU protection plate 4, so that the glue falls into the protective frame 205 and then reaches the top of the BMU protection plate 4. The protective frame 205 covers the specific area on the top of the BMU protection plate 4 to prevent the BMU protection plate 4 from dripping to other areas close to the specific part due to the tailing of glue after leaving the glue dripping tube 3. The tailing part of the glue is intercepted by the protective frame 205 and the glue is adhered to the inner wall of the protective frame 205.

[0031] See Figure 2-Figure 3 A gantry 6 is fixedly installed on the top of the dispensing device 1 , the screw rod 202 is rotatably connected to the gantry 6 , and the fan blades 203 and the bracket 204 are both located below the gantry 6 .

[0032] The gantry 6 supports the screw rod 202, so that when the slide 201 slides downward along the screw rod 202, the screw rod 202 can only rotate but not move. The fan blade 203 is located below the gantry 6, which is convenient for approaching the BMU protection plate 4 and cleaning the dust particles on the top of the BMU protection plate 4. The bracket 204 and the protective frame 205 are located below the gantry 6, which is convenient for the protective frame 205 to approach the top of the BMU protection plate 4.

[0033] See Figure 2-Figure 6 The protective frame 205 is hinged with a baffle 8, and an elastic rope 7 is fixedly connected between the baffle 8 and the gantry 6. The end of the elastic rope 7 away from the gantry 6 is located on the side of the baffle 8 away from the protective frame 205. A connecting rod 9 is fixedly installed on the outer wall of the protective frame 205, and a plurality of torsion springs 10 are connected to the outer wall of the connecting rod 9. The torsion springs 10 and the connecting rod 9 are both located at the connection between the protective frame 205 and the baffle 8.

[0034] In order to prevent the trailing glue from flowing along the inner wall of the protective frame 205 to the top of the BMU protection plate 4, the bottom of the protective frame 205 is blocked by the baffle 8. When the protective frame 205 moves downward, the baffle 8 is farther and farther away from the top of the gantry 6, so the elastic rope 7 will pull one side of the baffle 8 upward, so that the baffle 8 leaves the bottom of the protective frame 205. When the protective frame 205 moves upward, the elastic rope 7 will release the pull on the baffle 8, and then the multiple torsion springs 10 will bounce the baffle 8 back to the bottom of the protective frame 205. At this time, the baffle 8 blocks the bottom of the protective frame 205, preventing the glue stuck on the inner wall of the protective frame 205 from flowing to the top of the BMU protection plate 4.

[0035] See Figure 5-Figure 6 An absorbent pad 12 is provided inside the baffle 8 , and a plurality of through holes 13 are opened on one side of the baffle 8 , and the through holes 13 correspond to the inside of the protective frame 205 .

[0036] If the glue on the inner wall of the protective frame 205 slides directly to the top of the baffle 8, then after the baffle 8 tilts, the glue may slide along the outer wall of the baffle 8 and fall onto the BMU protective plate 4. Therefore, through holes 13 are opened and an absorption pad 12 is set. When the glue on the inner wall of the protective frame 205 flows to the top of the baffle 8, the glue will enter the interior of the baffle 8 along multiple through holes 13, and then the glue will flow onto the absorption pad 12. The absorption pad 12 can quickly absorb part of the solvent or moisture in the glue, causing the glue to solidify or become more viscous, thereby enhancing the adhesion between the glue and the absorption pad 12, so that the glue will not slide from the absorption pad 12, so as to prevent the glue from sliding onto the BMU protective plate 4.

[0037] See Figure 5 The baffle 8 defines a chamber 11 , and the absorbent pad 12 is located inside the chamber 11 . The absorbent pad 12 is slidably connected to the inner wall of the chamber 11 .

[0038] The chamber 11 provides a space for placing the absorbent pad 12 , and the absorbent pad 12 can be pulled out from the chamber 11 , which facilitates the replacement of the absorbent pad 12 and ensures the glue absorbing effect of the absorbent pad 12 .

[0039] See Figure 6 Two L-shaped fixing rods 14 are fixedly installed on the outer wall of the protective frame 205, and a support rod 15 is provided on one side of the protective frame 205. The end of the L-shaped fixing rod 14 away from the protective frame 205 is fixedly connected to the outer wall of the support rod 15, and the outer wall of the elastic rope 7 is against the outer wall of the support rod 15.

[0040] The L-shaped fixing rod 14 fixes the support rod 15 on one side of the protective frame 205. The support rod 15 supports the elastic rope 7 so that the elastic rope 7 will not directly contact the protective frame 205. The elastic rope 7 can be kept away from the protective frame 205, thereby preventing the glue from contacting the elastic rope 7 when the glue is being dispensed by the glue tube 3, and also preventing the elastic rope 7 from contacting the protective frame 205 and generating friction.

[0041] See Figure 6 Circular blocking plates 16 are fixedly installed at both ends of the support rod 15, and the elastic rope 7 is located between the two circular blocking plates 16.

[0042] The circular blocking plate 16 limits the two sides of the support rod 15 to prevent the elastic rope 7 from sliding off the outer wall of the support rod 15, so that the elastic rope 7 can maintain contact with the support rod 15.

[0043] See Figure 2-Figure 3 The inner top wall of the gantry 6 is fixedly mounted with a support rod 5, and the bracket 204 is slidably connected to the outer wall of the support rod 5.

[0044] The support rod 5 guides and limits the bracket 204. When the bracket 204 moves up and down, it will slide along the outer wall of the support rod 5. The support rod 5 not only supports the bracket 204, but also enables the bracket 204 to slide vertically, ensuring the accurate position of the protective frame 205 and avoiding the deviation of the protective frame 205.

[0045] Working principle:

[0046] In the prior art, the BMU protection plate 4 is first transferred to the bottom of the glue dripping tube 3 by the transmission structure on the glue dispensing device 1. The glue dripping tube 3 in the glue dispensing device 1 moves downward when dispensing glue on the BMU protection plate 4 until the glue outlet at the bottom of the glue dripping tube 3 is close to the top of the BMU protection plate 4. Then, the glue in the glue dripping tube 3 can drip from the bottom end of the glue dripping tube 3 to a specific area on the top of the BMU protection plate 4. When the glue dripping tube 3 moves downward, it drives the slide 201 to slide along the screw rod 202.

[0047] Since the connection between the slide plate 201 and the screw rod 202 is provided with a thread, and the thread inside the slide plate 201 is adapted to the screw rod 202, the screw rod 202 will rotate when the slide plate 201 moves downward along the outer wall of the screw rod 202. After the screw rod 202 rotates, it drives the fan blades 203 to rotate. The wind generated by the rotation of the fan blades 203 will blow the surface of the BMU protection plate 4, blowing off the dust on the surface of the BMU protection plate 4. The presence of dust particles will interfere with the accuracy of glue dispensing, resulting in uneven glue distribution or offset of the glue dispensing position. The fan blades 203 blowing off the dust can eliminate this interference, ensuring that the glue can be accurately applied to the predetermined position on the top of the BMU protection plate 4.

[0048] As the screw rod 202 rotates, the bracket 204 will also slide downward along the outer wall of the screw rod 202 until the bottom of the protective frame 205 is close to the top of the BMU protection plate 4. Then the glue dripping tube 3 drips glue to the BMU protection plate 4, so that the glue falls into the protective frame 205 and then reaches the top of the BMU protection plate 4. The protective frame 205 covers the specific area on the top of the BMU protection plate 4 to prevent the BMU protection plate 4 from dripping to other areas close to the specific part due to the tailing of glue after leaving the glue dripping tube 3. The tailing part of the glue is intercepted by the protective frame 205 and the glue is adhered to the inner wall of the protective frame 205.

[0049] In order to prevent the trailing glue from flowing along the inner wall of the protective frame 205 to the top of the BMU protection plate 4, the bottom of the protective frame 205 is blocked by the baffle 8. When the protective frame 205 moves downward, the baffle 8 is farther and farther away from the top of the gantry 6, so the elastic rope 7 will pull one side of the baffle 8 upward, so that the baffle 8 leaves the bottom of the protective frame 205. When the protective frame 205 moves upward, the elastic rope 7 will release the pull on the baffle 8, and then the multiple torsion springs 10 will bounce the baffle 8 back to the bottom of the protective frame 205. At this time, the baffle 8 blocks the bottom of the protective frame 205, preventing the glue stuck on the inner wall of the protective frame 205 from flowing to the top of the BMU protection plate 4.
