Description

Technical Field

[0002] The battery is a highly efficient energy storage and conversion device. The battery will generate heat during the energy conversion process. Existing batteries are usually equipped with cooling tubes for heat exchange cooling. The cooling tube is in contact with the inner core of the battery. In order to reduce the corrosion of the cooling tube by the inner core of the battery, a protective layer is provided on the outer layer of the cooling tube. The protective layer is achieved by a spraying process. The production cost of the spraying process is high, but the uniformity of the protective layer on the surface of the cooling tube is affected by the operation level, and it is difficult to achieve uniformity and consistency, resulting in the protective layer formed by spraying not being resistant to high pressure and high resistance. Moreover, the spraying process is polluting to the environment and has poor environmental protection. For this reason, some batteries use a protective film to form a protective layer on the cooling tube. The protective film wraps around the cooling tube for more than one week, forming an overlap at the end to reduce the risk of the protective film warping and cracking. It is difficult to form a uniform attachment for the slender cooling tube, and it is easy to form defects such as wrinkles and bubbles; if artificial film is used, the efficiency is low and the consistency of the film is poor.

[0017] Beneficial effects of the present invention:

[0018] The cooling tube coating device provided by the present invention is used to coat the outer circumference of the cooling tube with a protective film. The protective film is arranged around the axial direction of the cooling tube and in the outer circumference of the cooling tube. The length of the protective film extends along the length direction of the cooling tube. The width of the protective film is greater than the cross-sectional circumference of the cooling tube.

The cooling tube coating device includes a clamping and flipping assembly and a roller coating assembly. The clamping and flipping assembly includes a clamping mechanism and a flipping mechanism. The clamping mechanism is used to clamp the cooling tube, and the flipping mechanism is used to flip the cooling tube around the axial direction of the cooling tube. The roller coating assembly is used to press the protective film onto the cooling pipe.

After each coating operation of the roller coating assembly is completed along the surface of the cooling tube, the flipping mechanism flips the cooling tube around the axial direction of the cooling tube, and each rotation turns the side to be coated toward the roller coating assembly. Since the rotation direction of the cooling tube is opposite to the coating direction of the roller coating assembly, for example, the flipping mechanism flips the cooling tube counterclockwise, and the roller coating assembly coats the protective film clockwise along the circumference of the cooling tube; the flipping mechanism flips the cooling tube clockwise, and the roller coating assembly coats the protective film counterclockwise along the circumference of the cooling tube, thereby forming a roller coating assembly that sequentially coats the first end face, the first side face, the second end face, the second side face and the first end face, ensuring that each coating action of the roller coating assembly can continue to coat the end of the previous coating action, thereby ensuring the continuity and uniformity of the coating of the protective film and reducing the risk of defects such as wrinkles and bubbles; moreover, the roller coating assembly coats the first end face twice at the beginning and the end to ensure the formation of an overlap portion located at the first end face, thereby reducing the risk of cracking and warping of the protective film. No manual operation is required during the protective film application process, which improves the efficiency of film application and provides better consistency. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cooling tube coating device, which is used to coat a protective film 200 on the outer periphery of a cooling tube 100. The protective film 200 is arranged around the axial direction of the cooling tube 100 on the outer periphery of the cooling tube 100. The length of the protective film 200 extends along the length direction of the cooling tube 100. The width of the protective film 200 is greater than the cross-sectional circumference of the cooling tube 100. Therefore, the first end 201 and the second end 202 of the protective film 200 are partially overlapped to form an overlapped portion (refer to Figure 4 ), the overlap portion extends along the length direction of the cooling tube 100. The cooling tube 100 includes a first end face 101 and a second end face 102 arranged opposite to each other, and a first side face 103 and a second side face 104 connected between the first end face 101 and the second end face 102. The overlap portion is located on the first end face 101, and the overlap portion can reduce the risk of cracking and warping of the protective film 200. The positional relationship between the first end face 101, the first side face 103, the second end face 102 and the second side face 104 is not limited to the drawings of this embodiment, and can be Figure 3 Taking the viewing angle as an example, the first side surface 103 may be located on the right side of the first end surface 101 , or may be located on the left side of the first end surface 101 .

[0041] The cooling pipe coating device includes a clamping and flipping assembly 1 and a roller coating assembly 2. The clamping and flipping assembly 1 includes a clamping mechanism 11 and a flipping mechanism 12. The clamping mechanism 11 is used to clamp the cooling pipe 100, and the flipping mechanism 12 is used to flip the cooling pipe 100 around the axial direction of the cooling pipe 100. The roller coating assembly 2 is used to press the protective film 200 onto the cooling pipe 100. The rotation direction of the cooling pipe 100 is opposite to the pressing direction of the roller coating assembly 2. The roller coating assembly 2 presses the first end face 101, the first side face 103, the second end face 102, the second side face 104 and the first end face 101 in sequence around the axial direction of the cooling pipe 100 to form an overlapped portion. Each time the roller coating assembly 2 completes a coating along the surface of the cooling tube 100, the flipping mechanism 12 flips the cooling tube 100 around the axial direction of the cooling tube 100, and each rotation faces the side to be coated toward the roller coating assembly 2. Since the rotation direction of the cooling tube 100 is opposite to the coating direction of the roller coating assembly 2, for example, the flipping mechanism 12 flips the cooling tube 100 counterclockwise, and the roller coating assembly 2 coats the protective film 200 along the circumference of the cooling tube 100 clockwise; the flipping mechanism 12 flips the cooling tube 100 clockwise, and the roller coating assembly 2 coats the protective film 200 along the circumference of the cooling tube 100 counterclockwise. 00, and then the roller coating assembly 2 is pressed on the first end face 101, the first side face 103, the second end face 102, the second side face 104 and the first end face 101 in sequence, ensuring that each pressing action of the roller coating assembly 2 can continue to coat the end of the previous coating action, ensuring the continuity and uniformity of the coating of the protective film 200, and reducing the risk of defects such as wrinkles and bubbles; moreover, the roller coating assembly 2 performs two pressings on the first end face 101 at the beginning and the end to ensure the formation of the overlapped part located at the first end face 101, reducing the risk of cracking and warping of the protective film 200. No manual operation is required during the coating process of the protective film 200, which improves the efficiency of the film coating and has good consistency.

[0042] It should be noted that the roller coating assembly 2 can only coat one surface or two adjacent surfaces each time it coats. Figure 4 As shown, in one embodiment, the roller coating assembly 2 only coats the first end surface 101 in the first coating operation, and coats two adjacent surfaces in the subsequent two coating operations, i.e., the first side surface 103 and the second end surface 102 are coated once, and the second side surface 104 and the first end surface 101 are coated once, thereby simplifying the operation. Figure 4 The middle arrow a indicates the first coating action of the roller coating assembly 2, the arrow b indicates the second coating action of the roller coating assembly 2, and the arrow c indicates the third coating action of the roller coating assembly 2, thereby completing the coating of one cooling tube 100.

[0043] Specifically, the cooling pipe coating device includes a support platform 3, and the clamping and flipping assembly 1 is arranged on the support platform 3. Figures 5 to 7 As shown, the roller coating assembly 2 includes a movable bracket 21 and a rotating roller 22 rotatably disposed on the movable bracket 21. The rotating roller 22 is parallel to the length direction of the cooling tube 100, and the length of the rotating roller 22 is equal to the length of the protective film 200. The entire circumferential film coating of the cooling tube 100 can be completed by rolling along the circumference once, thereby improving the coating efficiency.

[0044] The rotating roller 22 can roll against the cooling pipe 100 to reduce friction during rolling. The movable bracket 21 can move in the X direction and the Z direction, both of which are perpendicular to the length direction of the cooling pipe 100. The X direction is the width direction of the cooling pipe 100, and the Z direction is the vertical direction. When moving in the X direction, the rotating roller 22 rolls the surface in a horizontal state, and when moving in the Z direction, the rotating roller 22 rolls the surface in a vertical state.

[0045] Since the length of the rotating roller 22 is relatively long, in order to keep the rotating roller 22 in a straight extension state along the entire length direction, thereby evenly applying roller pressure to the protective film 200, the roller coating assembly 2 further includes a plurality of pressing rollers 23. The pressing rollers 23 are rotatably arranged on the movable bracket 21, the pressing rollers 23 are located above the rotating roller 22, and the pressing rollers 23 can roll against the rotating roller 22. The plurality of pressing rollers 23 are arranged at intervals along the length direction of the rotating roller 22, and the positions of the pressing rollers 23 along the Z direction are adjustable. The pressing rollers 23 are used to squeeze the rotating roller 22 along the Z direction, so that the rotating roller 22 is kept in a straight extension state, and the middle part of the rotating roller 22 is prevented from bulging and failing to abut against the protective film 200. The position of the pressure roller 23 along the Z direction is adjustable, which is convenient for adjusting the distance between the axis of the rotating roller 22 and the rotating roller 22 in the Z direction, so as to obtain a suitable pressure for squeezing the rotating roller 22. A certain pressure along the Z direction can be applied to the rotating roller 22 to maintain the straight state of the rotating roller 22 so as to abut against the protective film 200 in the length direction, thereby ensuring the uniformity and consistency of the coating of the protective film 200 and reducing bubbles.

[0046] Optionally, two pressure rollers 23 are symmetrically arranged on both sides of the rotating roller 22 along the axial direction perpendicular to the rotating roller 22, so that the pressure applied to the rotating roller 22 is more balanced, avoiding the axial direction of the pressure roller 23 and the axial direction of the rotating roller 22 being not parallel to each other and affecting the normal rolling of the rotating roller 22.

[0047] In order to prevent the cooling pipe 100 from being damaged by excessive Z-direction pressure, an outer protective layer with a certain flexibility is mounted on the rotating roller 22. The outer protective layer has a buffering effect, so that the rotating roller 22 can withstand the pressure of the pressure roller 23 without completely transmitting the pressure to the cooling pipe 100.

[0048] The movable support 21 includes a support platform 211 and two mounting seats 212. The mounting seats 212 are constrained to be movable along the Z direction on the support platform 211. The two mounting seats 212 are respectively used to support both ends of the rotating roller 22. The rotating roller 22 is rotatably disposed on the mounting seats 212. The flip mechanism 12 can flip the cooling pipe 100 so that the first end face 101 and the second end face 102 are in a horizontal state. The rotating roller 22 moves along the X direction to roll the first end face 101 and the second end face 102. The rotating roller 22 moves along the Z direction to roll the first side face 103 and the second side face 104.

[0049] When the rotating roller 22 rolls the first end face 101 or the second end face 102, the rotating roller 22 is rotatably constrained between the cooling tube 100 and the pressing roller 23 to ensure that the cooling tube 100 can be rolled in the entire length direction; when the rotating roller 22 rolls the first side face 103 or the second side face 104, the mounting seat 212 moves along the Z direction to make the rotating roller 22 separate from the pressing roller 23. Because when the rotating roller 22 rolls the first side face 103 or the second side face 104 along the Z direction, the rotating roller 22 is still subjected to the pressure from the top to the bottom by the pressing roller 23, but there is no reaction force from the bottom to the top applied by the first end face 101 or the second end face 102. In the process of rolling along the first side face 103 or the second side face 104, the pressure of the pressing roller 23 will make the rolling resistance of the rotating roller 22 too large and unable to rotate during the movement, so sliding friction is formed between the rotating roller 22 and the first side face 103 or the second side face 104. Compared with rolling friction, the contact mode of sliding friction is more likely to form bubbles and wrinkles when pressing the protective film 200. Figure 7 As shown, by rotatably constraining the rotating roller 22 between the cooling tube 100 and the pressure roller 23, when the rotating roller 22 is on the first side 103 or the second side 104, it is driven by the mounting seat 212 to move along the Z direction and detach from the pressure roller 23, and then remains in a rolling state when rolling the first side 103 or the second side 104, thereby improving the appearance quality of the film.

[0050] Specifically, an adjustment hole is provided on the support platform 211, and an adjustment rod 213 is connected to the mounting seat 212. The adjustment rod 213 can be slidably inserted into the adjustment hole, and the end of the adjustment rod 213 is locked by a nut to limit the moving distance of the mounting seat 212. When the rotating roller 22 rolls the first end face 101 or the second end face 102, the height position of the rotating roller 22 is adjusted by moving the mobile support 21 along the Z direction to ensure that the rotating roller 22 abuts against the first end face 101 or the second end face 102, and the rotating roller 22 is constrained between the cooling pipe 100 and the pressure roller 23, and the adjustment rod 213 does not slide up and down. When the rotating roller 22 rolls the first side face 103 or the second side face 104, the rotating roller 22 is no longer subjected to the bottom-up reaction force exerted by the first end face 101 or the second end face 102, and the adjustment rod 213 slides downward in the adjustment hole, so that the distance between the rotating roller 22 and the pressure roller 23 becomes larger.

[0051] The cooling pipe coating device further includes a transfer assembly 4, which is movably disposed on the support platform 3, and includes a transfer suction cup 41, which is used to absorb the protective film 200. The transfer assembly 4 can move the protective film 200 along the X direction and the Z direction, and place the protective film 200 on the cooling pipe 100. In the initial state, the first end surface 101 faces upward to facilitate receiving the protective film 200.

[0052] like Fig. 9 and Fig.10As shown, the cooling tube coating equipment also includes a first shielding platform 5 and a second shielding platform 6, both of which are located above the cooling tube 100, and the first shielding platform 5 and the second shielding platform 6 are spaced apart along the X direction and are respectively located on both sides of the rotating roller 22, the first end 201 of the protective film 200 is located above the first shielding platform 5, the second end 202 of the protective film 200 is located on the second shielding platform 6, and part of the protective film 200 abuts the cooling tube 100, the shielding effect of the first shielding platform 5 and the second shielding platform 6 can prevent the two ends of the protective film 200 from abutting the cooling tube 100 in advance, and in the absence of the rolling effect of the rotating roller 22, the premature bonding of the protective film 200 will cause wrinkles, bubbles and other poor appearance in the subsequent rolling process. By adjusting the first shielding platform 5 and the second shielding platform 6, the protective film 200 that partially abuts the cooling tube 100 is located at the edge of the first end surface 101 close to the first side surface 103, so that it is convenient for the rotating roller 22 to start rolling from the edge of the first end surface 101 close to the first side surface 103, and move to the middle position on the first end surface 101 until it rolls to the first end 201 of the protective film 200. In the above process, the rotating roller 22 moves in a direction away from the second shielding platform 6 to roll the protective film 200 and press the first end 201 onto the first end surface 101. At the same time, the first shielding platform 5 moves in a direction away from the second shielding platform 6 to avoid the rotating roller 22.

[0053] After the first end 201 of the protective film 200 is attached to the first end surface 101, the flipping mechanism 12 can continuously flip the cooling tube 100, and make the second end surface 102 and the first end surface 101 face upward in sequence. For example, after the first flipping of the flipping mechanism 12, the second end surface 102 faces upward, and the rotating roller 22 rolls the first side surface 103 and the second end surface 102 in sequence; after the second flipping of the flipping mechanism 12, the first end surface 101 faces upward again, and the rotating roller 22 rolls the second side surface 104 and the first end surface 101 in sequence. In the above process, the cooling tube 100 rotates counterclockwise, and the rotating roller 22 rolls each surface clockwise to ensure the continuity of rolling.

[0054] In the process of the flipping mechanism 12 continuously flipping the cooling tube 100, the second shielding platform 6 is always located beside the cooling tube 100, and the second end 202 of the protective film 200 can be located on the second shielding platform 6. In the process of the rotating roller 22 rolling the first side surface 103 and the second end surface 102 in sequence, or rolling the second side surface 104 and the first end surface 101 in sequence, the second shielding platform 6 can lift the second end 202 of the protective film 200 to prevent the second end 202 of the protective film 200 from abutting the cooling tube 100 in advance. When the rotating roller 22 rolls the protective film 200 on the first side surface 103 or the second side surface 104 and moves in the direction close to the second shielding platform 6, the second shielding platform 6 moves in the direction away from the first shielding platform 5 to avoid the rotating roller 22, so as to prevent the second shielding platform 6 and the rotating roller 22 from colliding.

[0055] The second shielding platform 6 has a plurality of vacuum adsorption holes 61, such as Figure 8 The vacuum adsorption hole 61 is used to adsorb the second end 202 of the protective film 200. The vacuum adsorption hole 61 has an adsorption state and a non-adsorption state. When the rotating roller 22 moves in a direction away from the second shielding platform 6 and rolls the protective film 200, the vacuum adsorption hole 61 is in the adsorption state. When the flip mechanism 12 flips the cooling tube 100, the vacuum adsorption hole 61 is in the non-adsorption state. In order to achieve a better bonding effect at the first end 201 of the protective film 200, the first pressing of the rotating roller 22 on the first end surface 101 starts with the protective film 200 being rolled at a position on the first end surface 101 away from the first side surface 103, and this position is also the edge of the first end surface 101 close to the first side surface 103; during this process, the rotating roller 22 moves in a direction away from the second shielding platform 6. In order to prevent the second end 202 of the protective film 200 from moving during the rolling process of the rotating roller 22 and causing the protective film 200 to be misplaced on the cooling tube 100, the second shielding platform 6 is configured to have a vacuum adsorption hole 61, which can adsorb the second end 202 of the protective film 200 to ensure that the protective film 200 will not shift during the rolling process of the rotating roller 22.

[0056] refer to Figure 4 , the arrow a in the figure is the first pressing of the rotating roller 22 on the first end surface 101, and its arrow direction is different from the arrow b and arrow c, that is, arrow a is the trajectory of the rotating roller 22 moving from the edge of the first end surface 101 close to the first side surface 103 toward the direction of rolling the first end 201. It should be noted that the rotation direction of the cooling tube 100 is opposite to the pressing direction of the roller coating assembly 2, and the arrow a in the figure has a different direction from the arrow b and arrow c, which is not contradictory, because the pressing direction of the roller coating assembly 2 refers to the order in which it rolls several surfaces in sequence around the circumference of the cooling tube 100.

[0057] The rotating roller 22 can reciprocate along the X direction on the first end face 101 or the second end face 102 to the edge of the first end face 101 or the second end face 102 close to the second shielding platform 6. In order to further avoid the rotating roller 22, the upper surface of the second shielding platform 6 close to the rotating roller 22 is recessed downward to form an avoidance portion 62, and the avoidance portion 62 is used to avoid the rotating roller 22. The avoidance portion 62 is an arc-shaped surface to adapt to the cross-sectional shape of the rotating roller 22. In this way, the distance between the second shielding platform 6 and the rotating roller 22 can be smaller, and the second shielding platform 6 has a larger lifting area for the second end 202 of the protective film 200. Only the protective film 200 in the area near the rolling of the rotating roller 22 will abut against the cooling pipe 100, and the film pasting quality is better.

[0058] like Fig.11 As shown, the cooling pipe coating device also includes an unwinding component 7, which includes a film drawing component 71, a reel 72, an unwinding adsorption platform 73 and a cutting knife 74. The protective film 200 is wound on the reel 72, and the reel 72 is used to unwind the protective film 200. The film drawing component 71 is used to clamp the free end of the protective film 200 and pull the free end so that the protective film 200 extends from one end of the unwinding adsorption platform 73 to the other end. The unwinding adsorption platform 73 is used to adsorb the protective film 200. The cutting knife 74 is arranged between the reel 72 and the unwinding adsorption platform 73. The cutting knife 74 is used to cut the protective film 200 to form a protective film 200 size that meets the length requirement of the cooling pipe 100.

[0059] The unwinding adsorption platform 73 can be raised and lowered along the Z direction to avoid the film-pulling member 71. In this way, the free end of the protective film 200 pulled by the film-pulling member 71 can be moved along the length direction of the cooling tube 100 until the length of the protective film 200 unwound by the reel 72 meets the requirements. Then, the unwinding adsorption platform 73 rises along the Z direction until it abuts against the protective film 200. The unwinding adsorption platform 73 has an adsorption state and a non-adsorption state. Before the cutting knife 74 is actuated, the unwinding adsorption platform 73 is lifted along the Z direction to abut against the protective film 200, and is converted from the non-adsorption state to the adsorption state, so that the cutting knife 74 can cut the protective film 200. After the protective film 200 is cut, the unwinding adsorption platform 73 is converted to the non-adsorption state, and the protective film 200 on the unwinding adsorption platform 73 is adsorbed by the transfer component 4, and then the transfer component 4 transfers the protective film 200 to the cooling tube 100.

[0060] The film-pulling member 71 can reciprocate along the length direction of the cooling tube 100, and the unloaded unwinding adsorption platform 73 descends to avoid the film-pulling member 71. The film-pulling member 71 moves in the opposite direction and pulls the free end of the protective film 200 on the winding wheel 72 after cutting, preparing for the next unwinding and cutting.

[0061] When the cooling tube 100 is heated to a certain temperature, the coating effect of the protective film 200 is smoother. Therefore, the cooling tube coating equipment also includes a heating platform 81, which is used to carry the cooling tube 100. The heating platform 81 can heat the cooling tube 100 to raise it to a more suitable temperature. Furthermore, the heating platform 81 has a positioning mechanism 811, which is used to position the cooling tube 100 along the length direction of the cooling tube 100. The positioning mechanism 811 is two relative positioning surfaces arranged at both ends of the length direction of the cooling tube 100, and is also beneficial to the positioning step at the end of the cooling tube 100. The positioning step fits the positioning surface to complete the positioning of the cooling tube 100 in the length direction.

[0062] The clamping mechanism 11 includes a first clamping jaw 111 and a second clamping jaw 112 which are arranged opposite to each other. The first clamping jaw 111 and the second clamping jaw 112 are respectively located at two ends of the heating platform 81. The first clamping jaw 111 and the second clamping jaw 112 are respectively used to clamp two ends of the cooling pipe 100. The first clamping jaw 111 and the second clamping jaw 112 have clamping positions, which can be formed by clamping grooves in the first clamping jaw 111 and the second clamping jaw 112. The first shielding platform 5 or the second shielding platform 6 can push against the cooling pipe 100 along the X direction, and move the cooling pipe 100 from the heating platform 81 to the clamping position of the first clamping jaw 111 and the second clamping jaw 112, so as to realize the width direction positioning of the cooling pipe 100. The positioning method of the cooling pipe 100 is relatively simple. Therefore, the cooling pipe 100 can be loaded manually to save equipment space. The operator places the cooling pipe 100 on the heating platform 81 to determine the position of the cooling pipe 100 in the height direction; at the same time, the positioning mechanism 811 is used to position the cooling pipe 100 in the length direction; then, the first shielding platform 5 or the second shielding platform 6 can push the cooling pipe 100 along the X direction to position the cooling pipe 100 in the width direction.

[0063] Optionally, in one embodiment, the end of the avoidance portion 62 of the second shielding platform 6 forms a tube pushing surface 63 . Due to the existence of the avoidance portion 62 , the tube pushing surface 63 has a slightly smaller area and is a planar structure, which is more suitable for pushing the cooling tube 100 .

[0064] In one embodiment, after the protective film 200 is wrapped around the outer circumference of the cooling tube 100, the cooling tube 100 is hot-pressed by the hot-pressing platform 82, so that the protective film 200 has better reliability, is less prone to bulging and bubbling, and extends its service life.

[0065] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
