Description

Technical Field

[0001] The present invention relates to the technical field of battery coating, and in particular to an automatic blade battery coating device. Background Art

[0002] The traditional battery package blue film is also called the battery package film. It is generally produced by manual packaging, which leads to low production efficiency. In addition, fingerprints, sweat and other pollutants are easily left on the film, affecting the quality of the film.

[0003] Although the prior art proposes mechanized coating equipment that can automatically coat and improve coating efficiency, there are still certain usage defects. For example, in the battery coating device and coating equipment in patent number CN105514477B, a film pulling mechanism is provided to achieve the tensioning of the film, so that the film can be more effectively applied to the battery surface. However, the prior art directly pulls the film by moving the floating plate to achieve the tensioning of the film. However, the tensioned film is covered and attached to the battery, which easily produces large bubbles. Especially for blade batteries with a large area of ​​plane area, the bubbles generated during the coating process are more obvious, making the thickness of the blade battery after coating uneven, affecting subsequent processing. Therefore, there is an urgent need for a device that can coat blade batteries to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0040] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Reference Figure 1-Figure 6 The present invention provides an automated blade battery coating device, comprising:

[0043] Machine 1;

[0044] A feeding roller set for conveying blade batteries along the production line direction;

[0045] The film-drawing mechanism comprises a pair of clamping plates 4 arranged on the machine platform 1 and located at the rear end of the feeding roller group. The machine platform 1 is provided with a first driving assembly, and the driving end of the first driving assembly is connected to the pair of clamping plates 4 so that the pair of clamping plates 4 are close to or away from each other, and the pair of clamping plates 4 can be lifted and lowered in the vertical direction;

[0046] The coating roller group includes a pair of coating rollers 5 arranged on the side of the clamping plate 4 away from the feeding roller group. A second driving assembly is provided on the machine 1. The driving end of the second driving assembly is connected to the pair of coating rollers 5 so that the pair of coating rollers 5 can reciprocate along the width direction of the machine 1. The mutually approaching sides of the pair of coating rollers 5 have an elastic tendency in opposite directions, and the distance between the pair of coating rollers 5 is less than the thickness of the blade battery.

[0047] The present invention conveys the blade battery to between a pair of coating rollers 5 through a feeding roller group, and uses a pair of clamping plates 4 to pull the blue film 6 in the vertical direction to unfold the blue film 6, so that when the blade battery passes through the blue film 6, the blue film 6 directly coats the blade battery along the front and back sides of the blade battery. After the blue film 6 covers the front and back sides of the blade battery, the coating roller 5 reciprocates through the second driving component to unfold the blue film 6, and because the pair of coating rollers 5 have an elastic tendency to approach each other, the blue film 6 is squeezed to the surface of the blade battery, thereby realizing efficient and automated coating. In the coating process, the coating roller 5 reciprocates while squeezing to flatten the blue film 6 along the width direction of the blade battery. Compared with the traditional technology of directly covering the blue film 6 on the battery surface, the coating roller 5 reduces the contact end area of ​​the blue film 6 and the blade battery, and as the blade battery continues to move, the entire blade battery can be covered with the film, effectively reducing the situation of large bubbles appearing on the surface of the blade battery after filming, thereby realizing the improvement of coating efficiency and effect.

[0048] Specifically, the feed roller group includes a feed plate 3 fixedly connected to both sides of the machine 1, and a pair of feed rollers 2 are connected between the feed plates 3 in the vertical direction. A mechanical arm (not shown in the figure) is set at the front end of the machine 1 to grab the blade battery, and the blade battery is conveyed in the gap between the pair of feed rollers 2, so that the blade battery is moved horizontally to between a pair of coating rollers 5, and the blue film 6 is pulled by the clamping plate 4, so that the blue film 6 directly covers the front and back sides of the blade battery along one end of the blade battery, thereby improving the coating efficiency.

[0049] Furthermore, it also includes:

[0050] A pair of film-coating plates 7 are fixedly connected to two sides of the machine platform 1, and a pair of film-coating rollers 5 are connected between the pair of film-coating plates 7 along the vertical direction;

[0051] The reciprocating screw 8 is arranged between a pair of coating plates 7. The number of reciprocating screws 8 and coating rollers 5 is the same and they correspond one to one. The coating rollers 5 are threadedly sleeved on the reciprocating screw 8. The corresponding reciprocating screw 8 on the coating plate 7 is elastically slidably connected to the limit plate 9. The reciprocating screw 8 is fixedly connected to the limit plate 9. The two reciprocating screws 8 have an elastic tendency to move in opposite directions through the limit plate 9.

[0052] The coating roller 5 is rotatably supported by the coating plate 7, and the limiting plate 9 is elastically slidably connected to the coating plate 7. The reciprocating screw 8 is fixedly connected to the limiting plate 9, and the coating roller 5 is sleeved on the reciprocating screw 8, so as to realize the elastic connection between the pair of coating rollers 5. Moreover, under the driving force provided by the second driving component, the coating roller 5 rotates relative to the limiting plate 9, and the reciprocating screw 8 is fixedly connected to the limiting plate 9, so that the coating roller 5 threadedly sleeved on the reciprocating screw 8 can reciprocate.

[0053] Further, the second driving component includes:

[0054] The second motor 11 is fixedly connected to the outer wall of the limit plate 9. The output shaft of the second motor 11 is fixedly connected to a driving gear 12. The driving gear 12 is meshed with a driven gear 13. The driven gear 13 is coaxially sleeved on the reciprocating screw 8. The driven gear 13 is transfer-connected to the reciprocating screw 8.

[0055] A plurality of connecting rods 14 are axially and evenly spaced through the coating roller 5 . The two ends of the connecting rods 14 are respectively fixedly connected to two oppositely distributed driven gears 13 . The connecting rods 14 are in sliding connection with the coating roller 5 .

[0056] The second motor 11 rotates the driving gear 12, and the driving gear 12 drives the driven gear 13 to rotate. The driven gear 13 drives the coating roller 5 to rotate through the connecting rod 14. Since the connecting rod 14 is slidingly connected to the coating roller 5, and the driven gear 13 is coaxially connected to the reciprocating screw 8, when the coating roller 5 rotates, the reciprocating screw 8 drives the coating roller 5 to reciprocate, thereby fully tensioning the blue film 6, and as the blade battery moves, the coating roller 5 rolls in contact with the blade battery, and the tensioned blue film 6 is directly wrapped on the surface of the blade battery, thereby improving the coating effect.

[0057] Furthermore, the coating plate 7 is provided with two slide grooves in the vertical direction, and limiting grooves are provided on opposite sides of the inner wall of the slide groove. The limiting plate 9 is slidingly connected in the slide groove, and the two ends of the spring 10 are fixedly connected between the two ends of the limiting plate 9 and the inner wall of the adjacent slide groove.

[0058] By opening a limit groove, the limit plate 9 is stably slidably connected with the slide groove, and by fixing the spring 10 at the top and bottom ends of the limit plate 9, the limit plate 9 is elastically connected with the slide groove, and under the action of the spring 10, the pair of coating rollers 5 have an elastic tendency in opposite directions, so that the pair of coating rollers 5 can form a clamping rolling contact with the blade battery, so that the blue film 6 can effectively fit the surface of the blade battery.

[0059] Furthermore, it also includes:

[0060] Film feeding roller group: a support plate 18 is fixedly connected to one side of the machine 1, and the film feeding roller group is transferred to the support plate 18;

[0061] A pair of film-drawing plates 19 are relatively fixedly connected to two sides of the machine platform 1. A guide roller group is arranged at the top of the film-drawing plates 19. The film-feeding roller group is used to transport the blue film 6 along the direction of the guide roller group.

[0062] Specifically, the film feeding roller group includes a first film feeding roller 15, a second film feeding roller 16 and a third film feeding roller 17 connected to a support plate 18. The blue film 6 is sleeved on the first film feeding roller 15 and is transported successively through the second film feeding roller 16 and the third film feeding roller 17 along the direction of the guide roller group.

[0063] The blue film 6 is guided in the vertical direction by the guide roller group, so that a pair of clamps 4 can pull the blue film 6 in the vertical direction with the guide roller group as the starting point, forming an obstruction on the moving path of the blade battery. When the blade battery continues to move, the blue film 6 can cover the front and back sides of the blade battery to achieve film packaging.

[0064] Furthermore, the first driving component includes:

[0065] The lifting plate 20 is slidably connected between a pair of film drawing plates 19. A plurality of first cylinders 21 are fixedly connected to opposite sides of the lifting plate 20. A groove is provided at the top of the lifting plate 20. A pair of clamping plates 4 are relatively slidably connected in the groove. The piston end of the first cylinder 21 is fixedly connected to the adjacent clamping plates 4.

[0066] The lifting member is arranged on the film drawing plate 19 , and the lifting end of the lifting member is connected to the lifting plate 20 .

[0067] The first cylinder 21 is used to control a pair of clamping plates 4 to move closer to or farther from each other, thereby clamping the blue film 6. The clamping plates 4 are driven by the lifting member to stretch the blue film 6 in the vertical direction.

[0068] Furthermore, the lifting member includes a first linear guide rail 22, and a pair of membrane pulling plates 19 have empty grooves on their mutually adjacent sides. The first linear guide rail 22 is fixed in the empty grooves along the vertical direction. A first slider 23 is slidably connected to the first linear guide rail 22, and the first slider 23 is fixed to both ends of the lifting plate 20 respectively.

[0069] The first linear guide rail 22 moves the first slider 23 , and the first slider 23 drives the lifting plate 20 to move up and down.

[0070] Furthermore, the guide roller group includes a guide plate 24 fixedly connected to the top of the film drawing plate 19, a guide groove is opened in the center of the guide plate 24, motor plates 25 are respectively fixedly connected to the two sides of the top surface of the guide plate 24, a guide roller 26 is transferred between the two relatively arranged motor plates 25, two guide rollers 26 are symmetrically arranged along the center of the guide groove, a first motor 27 is fixedly connected to the outer wall of the motor plate 25, and the output shaft of the first motor 27 is coaxially fixed to the guide roller 26.

[0071] The guide roller 26 is rotated by the first motor 27, and the pair of guide rollers 26 rotate toward the guide groove, so that the blue film 6 led out from the film feeding roller can naturally hang down along the guide groove, which is convenient for the clamping plate 4 to clamp the end of the blue film 6 along the guide groove.

[0072] Furthermore, rubber pad layers 28 are respectively fixed to the mutually adjacent sides of the pair of clamping plates 4 .

[0073] The contact friction is increased by the rubber pad layer 28 , thereby increasing the clamping stability of the blue film 6 .

[0074] Furthermore, it also includes:

[0075] The bracket 29 is arranged on the side of the coating roller 5 away from the clamping plate 4. The bracket 29 is fixedly connected to the machine platform 1. The top of the bracket 29 extends horizontally to the top of the coating roller 5.

[0076] The cutter 31 is arranged at the bottom of the top of the bracket 29. The bottom of the top of the bracket 29 is provided with a mounting groove. A support plate 30 is slidably connected in the mounting groove. A second cylinder 32 is fixedly connected to the top of the bracket 29. The piston rod of the second cylinder 32 is fixedly connected to the support plate 30. A second linear guide rail 33 is fixedly connected to the bottom end of the support plate 30. A second slider 34 is slidably connected to the second linear guide rail 33. The bottom end of the second slider 34 is fixedly connected to the cutter 31.

[0077] The conveyor belt 35 for conveying the blade batteries out of the machine 1 is movably engaged with the side of the cutter 31 away from the coating roller 5 .

[0078] The cutter 31 is moved by the second linear guide rail 33 to cut the blue film 6 along the width direction of the machine 1, so that the size of the blue film 6 wrapped on the blade battery reaches an appropriate size, which satisfies the requirement of fully covering the battery surface without excessive waste. The second cylinder 32 is used to drive the support plate 30 to rise and fall, so as to ensure that the cutter 31 can cut the surface of the blue film 6. Finally, the coated blade battery is conveyed out of the machine 1 from the conveyor belt 35.

[0079] The working principle of the automatic blade battery coating device of the present invention is as follows:

[0080] The blade battery with an insulating layer on the surface is grabbed by a robot arm and passed into the machine 1 between a pair of feed rollers 2 in the horizontal direction, and one end of the blue film 6 is pulled out from the first film feed roller 15 in the machine 1 in advance, and is transported by the second film feed roller 16 and the third film feed roller 17 to make the blue film 6 pass through the guide roller 26 and pass into the guide groove, and the blue film 6 is clamped and fixed by the clamping plate 4, and the first linear slide rail moves downward in the vertical direction to stretch the blue film 6 into a barrier surface in the vertical direction.

[0081] At this time, the blade battery passing through the feeding roller 2 contacts the blue film 6 from the middle, and the blue film 6 covers the top and bottom surfaces of the blade battery until the blade battery enters between a pair of coating rollers 5. Since the spacing between the coating rollers 5 is smaller than the thickness of the blade battery, and supported by the spring 10 and the limit plate 9, the pair of coating rollers 5 squeeze and contact the blade battery from beginning to end. During the process, the first motor 27 drives the driving gear 12 to rotate, so that the driven gear 13 rotates a number of connecting rods 14, and the coating rollers 5 are driven by the connecting rods 14 to rotate around the reciprocating screw 8, and the connecting rods 14 are slidably connected to the coating rollers 5, so that the coating rollers 5 rotate and reciprocate at the same time, thereby unfolding the blue film 6, and the unfolded area can directly fit with the surface of the blade battery under the action of the spring 10, thereby improving the effect of the blade battery coating and effectively reducing the generation of large bubbles.

[0082] After the blade battery continuously moves through the coating roller 5, the blue film 6 effectively and directly coats the front and back of the blade battery, and the coated blade battery moves directly to the top surface of the conveyor belt 35. At this moment, the blue film 6 on the rear end of the blade battery is connected to the clamp plate 4 and the guide roller 26 respectively, and the two layers of blue film 6 overlap. The cutter 31 is driven down by the second cylinder 32, and the second linear guide rail 33 moves the cutter 31 to one side of the blue film 6 and moves the cutter 31 along the width direction of the machine 1. The cutter 31 directly cuts the blue film 6 to complete the coating operation of the blade battery. Finally, the first cylinder 21 drives the clamp plates 4 away from each other, so that the cut part of the blue film 6 directly falls into the waste trough opened on the top surface of the machine 1, and the blue film 6 of the guide roller 26 also extends out of the guide groove under the pulling of the blade battery. After cutting, part of the blue film 6 naturally hangs down. By lifting the clamp plate 4 to repeatedly clamp and stretch the blue film 6, a large number of blade batteries can be repeatedly coated, thereby improving the coating efficiency.
