Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a material strip adsorption device and laser cutting equipment. Background Art

[0002] When the laser cutting machine cuts the pole piece strip, the fixing device located on the upper part of the pole piece strip will fix the pole piece strip for laser cutting. After the pole piece strip is cut, the adsorption device located at the lower part of the pole piece strip is used to adsorb and transport the pole piece strip after cutting, so that the pole piece body of the pole piece strip can be separated from the waste generated after cutting.

[0003] The existing adsorption device generally provides adsorption force for the pole piece strip through a negative pressure cavity. When the adsorption device at the bottom of the pole piece strip adsorbs the pole piece strip after cutting, the adsorption force of a single negative pressure cavity is easily insufficient. Under high-speed transportation, the pole piece strip cannot be stably adsorbed on the conveyor belt, resulting in jitter or deviation, causing the laser of the laser cutting machine to be unable to stably focus on the pole piece strip to cut the pole piece strip, affecting production efficiency.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Figure 1 It is a structural schematic diagram of an embodiment of the material belt adsorption device of the utility model; Figure 2 For this utility model Figure 1 The local enlarged image after removing the occlusion at point A in the middle; Figure 3 It is a schematic structural diagram of multiple conveyor belts of an embodiment of the material belt adsorption device of the utility model; Figure 4 1 is a partial structural diagram of an embodiment of the material belt adsorption device of the present utility model. In the embodiment of the present utility model, the material belt adsorption device 100 includes a conveying component 110 and an adsorption component 120.

[0032] The conveying assembly 110 includes multiple drive rollers and multiple conveyor belts 114 for conveying the cut electrode material strips. The outer peripheral surface of the drive roller has multiple limiting grooves 115 corresponding to the conveyor belts 114. The extension direction of the limiting grooves 115 is the same as the extension direction of the conveyor belts 114. The multiple conveyor belts 114 pass through multiple drive rollers and are limited in the corresponding limiting grooves 115, so that there are gaps between the multiple conveyor belts 114.

[0033] A plurality of transmission rollers are disposed around the circumference of the adsorption assembly 120, so that the plurality of conveyor belts 114 are moved around relative to the adsorption assembly 120. The adsorption assembly 120 includes a plurality of negative pressure cavities connected to the outside, and the plurality of negative pressure cavities provide adsorption force to the pole piece material belts at different positions of the conveyor belt 114, so that at least part of the pole piece material belts are adsorbed on the conveyor belt 114.

[0034] In an embodiment of the utility model, after the pole piece material strip is laser cut, the multiple negative pressure cavities of the adsorption assembly 120 respectively adsorb and fix the pole piece material strip at different positions of the conveyor belt 114, and can apply adsorption force to the pole piece material strip through the gaps between the multiple conveyor belts 114, so that the pole piece material strip is adsorbed on the conveyor belt 114.

[0035] In this embodiment, multiple negative pressure cavities provide adsorption force to the pole piece material belt on the conveyor belt 114 through the adsorption holes. Since multiple conveyor belts 114 pass through multiple transmission rollers and are limited in the limit grooves 115 of the transmission rollers, multiple conveyor belts 114 are spaced apart from each other, so that the negative pressure cavity can adsorb the pole piece material belt through the gaps between the conveyor belts 114, and ensure that the overall force of the pole piece material belt is uniform under the premise of sufficient adsorption force, so as to prevent the pole piece material belt from shaking or deviating under high-speed transportation, thereby affecting laser cutting.

[0036] Furthermore, the shape of the adsorption hole can be circular, square, elliptical or long, etc., and multiple adsorption holes are arranged at intervals to cooperate with the conveyor belt 114, so that the adsorption force of the negative pressure cavity can act on the electrode material belt located in the gap of the conveyor belt 114 through the adsorption holes, ensuring that the electrode material belt can always be subjected to the adsorption force from the negative pressure cavity when being transported on the conveyor belt 114.

[0037] The conveying component 110 of the material strip adsorption device 100 of the embodiment of the utility model is arranged around the adsorption component 120, so that the multiple negative pressure chambers of the adsorption component 120 can generate adsorption force to different positions of the conveyor belt 114, and the cut electrode material strips are adsorbed on the conveyor belt 114 through the gaps between the multiple conveyor belts 114, so as to fix the electrode material strips and prevent the electrode material strips from shaking or deviating during the conveying process, which affects the laser cutting.

[0038] In some embodiments, the conveying component 110 includes a first drive roller 111, the adsorption component 120 includes a first negative pressure cavity 121 and a plurality of first adsorption holes 124, the first adsorption holes 124 are connected to the first negative pressure cavity 121 and are located on the side wall of the first negative pressure cavity 121, and the openings of the first adsorption holes 124 face the conveyor belt 114; the first drive roller 111 is located on the side of the first negative pressure cavity 121 away from the ground, and the first negative pressure cavity 121 provides adsorption force to the pole piece belt through the first adsorption holes 124, so that at least part of the pole piece belt is adsorbed on the conveyor belt 114.

[0039] In this embodiment, the pole piece material strip after laser cutting will first be adsorbed on the conveyor belt 114 at the first transmission roller 111 by the adsorption force generated by the first negative pressure cavity 121. A plurality of first adsorption holes 124 are arranged on two adjacent side walls of the first negative pressure cavity 121 and face the conveyor belt 114, so as to ensure that the pole piece material strip after laser cutting can be stably adsorbed on the conveyor belt 114 when being transported at a high altitude by the conveyor belt 114, and prevent the pole piece material strip from shaking or deflecting.

[0040] Figure 2 for Figure 1 The local enlarged image after removing the occlusion at A in the middle is as follows Figure 2 As shown, in some embodiments, the conveying component 110 also includes a second drive roller 112, and the adsorption component 120 also includes a second negative pressure cavity 122 and an isolation plate 127, the isolation plate 127 forms a partial side wall of the second negative pressure cavity 122, and the isolation plate 127 has an adsorption port 1271, and the adsorption port 1271 is connected to the second negative pressure cavity 122 and faces the second drive roller 112; the second negative pressure cavity 122 can provide adsorption force to the pole piece material belt located at the second drive roller 112 through the adsorption port 1271, so that the pole piece body of the pole piece material belt is separated from the waste, and the waste is adsorbed on the conveyor belt 114.

[0041] In this embodiment, when the conveyor belt 114 transports the pole piece material strip to the position of the second drive roller 112, the second negative pressure cavity 122 provides adsorption force to the pole piece material strip located at the second drive roller 112 through the adsorption port 1271 on the isolation plate 127. The adsorption force of the second negative pressure cavity 122 on the pole piece material strip at the second drive roller 112 is controlled by setting the adsorption port 1271 on the isolation plate 127, so that the adsorption force on the pole piece material strip located at the second drive roller 112 is smaller than the adsorption force applied to the pole piece material strip by the multiple first adsorption holes 124, and the waste of the pole piece material strip is adsorbed on the conveyor belt 114, ensuring that the pole piece body and the waste can be separated smoothly.

[0042] Furthermore, the second negative pressure chamber 122 is located on the side of the first negative pressure chamber 121 close to the ground; the adsorption assembly 120 also includes a plurality of second adsorption holes 125, which are connected to the second negative pressure chamber 122 and are located on the side wall of the second negative pressure chamber 122, and the openings of the second adsorption holes 125 face the conveyor belt 114. The second negative pressure chamber 122 provides adsorption force to the waste on the conveyor belt 114 through the second adsorption holes 125, so that the waste is adsorbed on the conveyor belt 114.

[0043] In this embodiment, after the waste is adsorbed on the conveyor belt 114, the pole piece body is separated from the waste, and the conveyor belt 114 can transport the separated waste to the waste box 200. Since the second negative pressure cavity 122 is located on the side of the first negative pressure cavity 121 close to the ground and the second transmission roller 112 is located between the first negative pressure cavity 121 and the second negative pressure cavity 122, the second negative pressure cavity 122 will generate adsorption force to the waste on the conveyor belt 114 through the second adsorption hole 125, ensuring that the waste is adsorbed on the conveyor belt 114, so that the conveyor belt 114 can transport the waste to the waste box 200.

[0044] In some embodiments, the conveying component 110 also includes a third drive roller 113, and the adsorption component 120 also includes a third negative pressure cavity 123 and a plurality of third adsorption holes 126, the third adsorption holes 126 are connected to the third negative pressure cavity 123 and are located on the side wall of the third negative pressure cavity 123, and the opening of the third adsorption holes 126 faces the conveyor belt 114; the third drive roller 113 is located on the side of the third negative pressure cavity 123 close to the ground, and the third negative pressure cavity 123 provides adsorption force to the waste on the conveyor belt 114 through the third adsorption holes 126, so that the waste is adsorbed on the conveyor belt 114 and guided to the waste box 200.

[0045] In this embodiment, after the waste on the conveyor belt 114 passes through the second adsorption hole 125 of the second negative pressure cavity 122, the third adsorption hole 126 of the third negative pressure cavity 123 can replace the second adsorption hole 125 to provide adsorption force to the waste on the conveyor belt 114, so that the waste is adsorbed on the conveyor belt 114. When the waste is transported to the third transmission roller 113 by the conveyor belt 114, the waste will lose the adsorption force from the third negative pressure cavity 123 and fall into the waste box 200 located below the third negative pressure cavity 123.

[0046] Furthermore, the third negative pressure chamber 123 is located on a side of the second negative pressure chamber 122 close to the ground.

[0047] In this embodiment, the height of the third adsorption hole 126 of the third negative pressure cavity 123 relative to the ground is lower than the height of the second adsorption hole 125 of the second negative pressure cavity 122 relative to the ground. After the waste on the conveyor belt 114 passes through the second adsorption hole 125 of the second negative pressure cavity 122, the third adsorption hole 126 of the third negative pressure cavity 123 can continue to adsorb the waste on the conveyor belt 114 to prevent the waste from falling during the transportation process.

[0048] Figure 4 It is a partial structural schematic diagram of an embodiment of the material strip adsorption device of the utility model; Figure 5 This is a front view of the second negative pressure chamber and the third negative pressure chamber of an embodiment of the material strip adsorption device of the utility model. Figure 4As shown, in an embodiment of the utility model, the shape of the adsorption hole is circular or elongated, and a plurality of circular first adsorption holes 124 are arranged on the side wall and / or the top wall of the first negative pressure cavity 121. The first adsorption holes 124 located on the side wall of the first negative pressure cavity 121 face the conveyor belt 114 between the first transmission roller 111 and the second transmission roller 112, and the plurality of first adsorption holes 124 on the top wall face the conveyor belt 114 between the first transmission roller 111 and the adjacent fourth transmission roller 116, so that the pole piece material belt located before and after the first transmission roller 111 can be stably adsorbed on the conveyor belt 114.

[0049] like Figure 5 As shown, in an embodiment of the present utility model, the second adsorption hole 125 and the third adsorption hole 126 are in the shape of elongated strips, and a plurality of second adsorption holes 125 and a plurality of third adsorption holes 126 in the shape of elongated strips are respectively arranged on the side walls of the second negative pressure cavity 122 and the side walls of the third negative pressure cavity 123 for adsorbing waste.

[0050] In other embodiments, the first adsorption hole 124 may also be in the shape of an elongated strip. The first adsorption hole 124 in the shape of an elongated strip is arranged on the side wall and / or the top wall of the first negative pressure chamber 121. The first adsorption hole 124 located on the side wall of the first negative pressure chamber 121 faces the conveyor belt 114 between the first drive roller 111 and the second drive roller 112. The multiple first adsorption holes 124 on the top wall face the conveyor belt 114 between the first drive roller 111 and the adjacent fourth drive roller 116, so that the pole piece material belt located before and after the first drive roller 111 can be stably adsorbed on the conveyor belt 114. The multiple second adsorption holes 125 and the multiple third adsorption holes 126 in the shape of an elongated strip are respectively arranged on the side wall of the second negative pressure chamber 122 and the side wall of the third negative pressure chamber 123 for adsorbing waste.

[0051] The adsorption holes in the embodiment of the utility model can also be arranged in other shapes and layouts to adsorb the electrode strip onto the conveyor belt, and the utility model is not limited thereto.

[0052] In some embodiments, an extension direction of the plurality of conveyor belts 114 between the first transmission roller 111 and the second transmission roller 112 and an extension direction of the plurality of conveyor belts 114 between the second transmission roller 112 and the third transmission roller 113 form an angle.

[0053] Since waste will be generated after the pole piece strip is cut by laser, it is necessary to separate the pole piece body of the pole piece strip from the waste in order to carry out subsequent production and manufacturing.

[0054] In this embodiment, the second negative pressure chamber 122 is located on the side of the first negative pressure chamber 121 close to the ground, and the third negative pressure chamber 123 is located on the side of the second negative pressure chamber 122 close to the ground. The direction of movement of the conveyor belt 114 from the first transmission roller 111 to the second transmission roller 112, and then from the second transmission roller 112 to the third transmission roller 113 is roughly from the side of the material belt adsorption device 100 away from the ground to the side close to the ground.

[0055] When the pole piece material belt is transported from the first drive roller 111 to the second drive roller 112 by the conveyor belt 114, the pole piece body and the waste of the pole piece material belt are separated. Since the extension direction of the multiple conveyor belts 114 located between the first drive roller 111 and the second drive roller 112 has an angle with the extension direction of the multiple conveyor belts 114 located between the second drive roller 112 and the third drive roller 113, the conveyor belt 114 that changes the conveying direction can guide the waste adsorbed on the conveyor belt 114 into the waste box 200, while the pole piece body is still transported along the original direction.

[0056] Furthermore, a plurality of conveyor belts 114 located between the first transmission roller 111 and the second transmission roller 112 extend in a direction substantially perpendicular to the ground.

[0057] In this embodiment, the extension direction of the multiple conveyor belts 114 located between the second drive roller 112 and the third drive roller 113 has an angle with the direction approximately perpendicular to the ground, so that the pole piece body will continue to be transported to the subsequent processing position along the direction approximately perpendicular to the ground, and the waste is separated from the pole piece body and guided into the waste box 200 by the conveyor belt 114.

[0058] In some embodiments, the material strip adsorption device 100 also includes a first negative pressure pipe 130, a second negative pressure pipe 140 and a third negative pressure pipe 150 connected to the outside, the first negative pressure pipe 130 is also connected to the first negative pressure cavity 121, the second negative pressure pipe 140 is also connected to the second negative pressure cavity 122, and the third negative pressure pipe 150 is also connected to the third negative pressure cavity 123.

[0059] In this embodiment, the first negative pressure pipe 130 provides negative pressure to the first negative pressure cavity 121, the second negative pressure pipe 140 provides negative pressure to the second negative pressure cavity 122, and the third negative pressure pipe 150 provides negative pressure to the third negative pressure cavity 123. Each negative pressure pipe applies negative pressure to a negative pressure cavity separately, so that each negative pressure cavity can apply sufficient adsorption force to different positions of the conveyor belt 114, thereby preventing a single negative pressure cavity from having insufficient adsorption force, causing the pole piece material belt to shake or deviate.

[0060] In some embodiments, the material strip adsorption device 100 also includes at least one fourth transmission roller 116, the second transmission roller 112 is located on one side of the adsorption component 120, and the fourth transmission roller 116 is located on the other side of the adsorption component 120 and has a plurality of limiting grooves 115. By surrounding the plurality of transmission rollers around the adsorption component 120, the conveyor belt 114 can make a circular motion relative to the adsorption component 120, continuously adsorbing and separating the cut electrode material strips and directing the separated waste to the waste box 200.

[0061] The present invention further provides a laser cutting device, wherein the main laser cutting device comprises the material strip adsorption device 100 and a cutting device according to any of the aforementioned embodiments of the present invention.

[0062] The material strip adsorption device 100 is arranged on one side of the cutting device. The cutting device can generate laser and control the laser to cut the pole piece material strip. The pole piece material strip after being cut can be adsorbed on the conveying component 110 by the adsorption component 120 of the material strip adsorption device 100 .

[0063] The material strip adsorption device 100 includes a conveying assembly 110 and an adsorption assembly 120. The conveying assembly 110 includes a plurality of transmission rollers and a plurality of conveyor belts 114 for conveying the cut electrode strips. The outer peripheral surface of the transmission roller has a plurality of limiting grooves 115 corresponding to the conveyor belts 114. The extending direction of the limiting grooves 115 is the same as the extending direction of the conveyor belts 114. The plurality of conveyor belts 114 pass through the plurality of transmission rollers and are limited in the corresponding limiting grooves 115, so that there are gaps between the plurality of conveyor belts 114.

[0064] A plurality of transmission rollers are disposed around the circumference of the adsorption assembly 120, so that the plurality of conveyor belts 114 are moved around relative to the adsorption assembly 120. The adsorption assembly 120 includes a plurality of negative pressure cavities connected to the outside, and the plurality of negative pressure cavities provide adsorption force to the pole piece material belts at different positions of the conveyor belt 114, so that at least part of the pole piece material belts are adsorbed on the conveyor belt 114.

[0065] In this embodiment, the laser generated by the cutting device can cut the pole piece strip. After the cutting is completed, pole piece waste will be generated. The cut pole piece strip is adsorbed to the first transmission roller 111 by the strip adsorption device 100 and transported by the conveyor belt 114. In the subsequent transportation process, the waste is smoothly separated from the pole piece body through the adsorption force of multiple negative pressure cavities for subsequent production and manufacturing.

[0066] The laser cutting equipment of the embodiment of the utility model includes a material belt adsorption device 100, and the conveying component 110 of the material belt adsorption device 100 is arranged around the adsorption component 120, so that the multiple negative pressure chambers of the adsorption component 120 can generate adsorption force to different positions of the conveyor belt 114, and the cut pole piece material belt is adsorbed on the conveyor belt 114 through the gaps between the multiple conveyor belts 114, so as to fix the pole piece material belt and prevent the pole piece material belt from shaking or deviating during the transportation process, which affects the laser cutting, so that the laser cutting equipment can avoid the problem of laser defocusing caused by the shaking of the pole piece material belt.
