Description

Technical Field

[0001] This invention relates to the field of material stripping technology, specifically to a stripping system for steel coils. Background Technology

[0002] In the modern 3C industry, many contact points in the casing need to be fitted with small steel sheets to increase the conductivity of the contacts. However, because the small steel sheets are very small, usually only 1.6mm×1.3mm, and these small auxiliary material rolls are supplied in multiple rows, that is, a roll of auxiliary material contains multiple small steel sheets.

[0003] Currently, in order to peel the small steel sheet from the auxiliary material roll, a peeling mechanism is usually used to peel the small steel sheet. The existing peeling mechanism uses vacuum suction to peel the small steel sheet from the auxiliary material roll. That is, the vacuum nozzle is facing the small steel sheet, and the negative pressure is used to make the small steel sheet detach from the auxiliary material roll to complete the peeling.

[0004] Because the auxiliary material roll is long and narrow, the beginning and end of the roll need to be compacted when peeling off the small steel sheets to prevent it from detaching from the conveying equipment. However, a large negative pressure can easily cause the steel sheets to deform when they are adsorbed. Alternatively, a certain threshold of negative pressure can be used for peeling to avoid this situation. However, this value of negative pressure can only peel off small steel sheets with stable adhesion and low viscosity. Therefore, existing peeling equipment cannot completely peel off all the small steel sheets from the auxiliary material roll, resulting in material waste. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a stripping system for steel sheet coils, so as to solve the technical problem in the prior art that existing stripping equipment is difficult to completely strip all small steel sheets from the auxiliary material coil, resulting in material waste.

[0006] The present invention provides a stripping system for steel sheet coils, including a support, a transmission device disposed on the support for transmitting the steel sheet coil, a detection device, and a stripping device;

[0007] Both the detection device and the stripping device are located on the transport path of the steel sheet roll. The detection device is used to detect the number of steel sheets on the steel sheet roll.

[0008] The peeling device includes a peeling plate and a telescopic adsorption machine. The peeling plate is movably connected to the support. By adjusting the tilt angle of the peeling plate, at least one edge of the peeling plate abuts against a portion of the steel sheet roll, so that a portion of the steel sheet roll is transported in at least one tilt direction during transmission, causing a portion of the steel sheets on the steel sheet roll to be lifted according to the tilt direction.

[0009] The telescopic adsorption machine and the detection device are electrically connected. The telescopic adsorption machine drives the suction nozzle on the telescopic adsorption machine to telescopically move according to the number of steel sheets. The suction nozzle is used to squeeze a part of the raised steel sheets, so that another part of the steel sheets are raised with the edge of the peeling plate as the fulcrum. Then, the suction nozzle adsorbs the two raised parts of steel sheets, so that the steel sheets are peeled off from the steel sheet roll.

[0010] Furthermore, the stripping system also includes a vacuum adsorption device, which is located on the steel roll transport path and before the stripping device. The vacuum adsorption device is used to adsorb the transported steel roll, so that the portion of the steel roll before the stripping device is transported without bending.

[0011] Furthermore, the support is also provided with a slide rail for the vacuum adsorption device to slide, and the vacuum adsorption device slides along the length direction of the slide rail to adjust the position of the vacuum adsorption device relative to the steel sheet roll.

[0012] Furthermore, the stripping system also includes a counterweight device, which is used to apply pressure to the vacuum adsorption device, so that when the vacuum adsorption device adsorbs the steel roll, the vacuum adsorption device applies a tensile force in the opposite direction of the transport of the steel roll, thereby straightening the steel roll.

[0013] Furthermore, the counterweight device includes a counterweight block, a flexible connector, and at least one steering component;

[0014] The steering component is mounted on the connecting component. One end of the flexible connecting component is connected to the counterweight, and the other end is connected to the vacuum adsorption device after being turned by the steering component, so that the counterweight can apply a pulling force to the vacuum adsorption device.

[0015] Furthermore, multiple steering components are provided, and these steering components are staggered on the bracket, so that the flexible connector can be connected to the vacuum adsorption device after multiple steering maneuvers.

[0016] Furthermore, the support includes a support frame and a material rack rotatably connected to the support frame;

[0017] The transmission device, the detection device, the peeling device, and the vacuum adsorption device are all mounted on the support frame, and the steel sheet is rolled on the material rack.

[0018] Furthermore, the transmission device includes multiple drive rollers, all of which are mounted on the support to transmit the steel sheet roll via the multiple drive rollers.

[0019] Furthermore, the transmission device also includes a telescopic component;

[0020] In this configuration, at least two of the multiple drive rollers are arranged opposite each other, and one of the two oppositely arranged drive rollers is connected to a telescopic member. The telescopic member drives one of the drive rollers to telescopically move, thereby adjusting the distance between the two oppositely arranged drive rollers to compact a portion of the steel sheet coil.

[0021] Furthermore, the telescopic component is located at the end of the steel sheet roll transport path.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] In the steel sheet roll peeling system provided by this invention, a peeling device is set on a support. This peeling device includes a peeling plate movably connected to the support. By adjusting the tilt angle of the peeling plate, at least one edge of the peeling plate abuts against a portion of the steel sheet roll. That is, by utilizing the material characteristic that the steel sheet itself has a certain hardness, adjusting the angle of the peeling plate allows a portion of the steel sheet on the steel sheet roll to be lifted off the roll during transport. Then, the suction nozzle on the telescopic suction machine in the peeling device performs a telescopic movement, causing another portion of the steel sheet to be lifted off the edge of the peeling plate. The suction nozzle then adsorbs the two lifted portions of the steel sheet, allowing the steel sheet to be completely peeled off the roll. Compared to the direct vacuum suction method in the prior art, this invention, during the transport of the steel sheet roll, first uses an tilted peeling plate to lift two parts of the steel sheet, and then uses a suction nozzle to pick them up. This achieves the peeling process with a smaller suction force, solving the technical problems of difficulty in peeling due to the inability to adjust the appropriate negative pressure and the unstable adhesive of the steel sheet backing in the prior art. This results in a stable and reliable peeling effect on the steel sheet. Attached Figure Description

Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Please see Figures 1 to 2 The figure shows a stripping system for steel sheet coils in one embodiment of the present invention, including a support 100, a transmission device 200 disposed on the support 100 for transmitting the steel sheet coils, a detection device 300, and a stripping device 400.

[0031] Both the detection device 300 and the stripping device 400 are located on the transport path of the steel sheet roll. The detection device 300 is used to detect the number of steel sheets on the steel sheet roll.

[0032] The peeling device 400 includes a peeling plate 410 and a telescopic adsorption machine 420. The peeling plate 410 is movably connected to the support 100. By adjusting the tilt angle of the peeling plate 410, at least one edge of the peeling plate 410 abuts against a portion of the steel sheet roll, so that a portion of the steel sheet roll is transported in at least one tilt direction during transmission, causing a portion of the steel sheets on the steel sheet roll to be lifted according to the tilt direction.

[0033] The telescopic adsorption machine 420 and the detection device 300 are electrically connected. The telescopic adsorption machine 420 drives the suction nozzle 430 on the telescopic adsorption machine 420 to telescopically move according to the number of steel sheets. The suction nozzle 430 is used to squeeze a part of the raised steel sheets, so that another part of the steel sheets are raised with the edge of the peeling plate 410 as the fulcrum. Then, the suction nozzle 430 adsorbs the two parts of raised steel sheets so that the steel sheets are peeled off from the steel sheet roll.

[0034] In other words, by setting a peeling device 400 on the support 100, the peeling device 400 includes a peeling plate 410 movably connected to the support 100. By adjusting the tilt angle of the peeling plate 410, at least one edge of the peeling plate 410 abuts against a portion of the steel sheet roll. That is, by utilizing the material property that the steel sheet itself has a certain hardness, adjusting the angle of the peeling plate 410 can cause a portion of the steel sheet on the steel sheet roll to be lifted off the roll during transport. Subsequently, the suction nozzle 430 on the telescopic suction machine 420 in the peeling device 400 performs a telescopic movement, thereby allowing another portion of the steel sheet to be lifted off the roll. After the sheet is lifted up using the edge of the peeling plate 410 as a fulcrum, the suction nozzle 430 adsorbs the two lifted parts of the steel sheet to completely peel the steel sheet off the steel sheet roll. Compared with the direct vacuum suction method in the prior art, the present invention first uses the inclined peeling plate 410 to lift up the two parts of the steel sheet during the transport of the steel sheet roll, and then uses the suction nozzle 430 to pick it up. This achieves the peeling process of the steel sheet with a smaller suction force, which solves the technical problems of the prior art, such as the inability to adjust the appropriate negative pressure and the unstable adhesive of the steel sheet, which makes the peeling difficult. This results in a stable and reliable peeling effect on the steel sheet.

[0035] It should be noted that the bracket 100 is provided with an arc-shaped or irregularly shaped through hole for the peeling plate 410 to move. In some actual situations, in order to ensure that the peeling plate 410 is fixed on the bracket 100, it can be fixed by external bolts, which will not be specifically explained here.

[0036] In some preferred embodiments, the stripping system further includes a vacuum adsorption device 500, which is located on the steel roll transport path and before the stripping device 400. The vacuum adsorption device 500 is used to adsorb the transported steel roll, so that the portion of the steel roll before the stripping device 400 is transported without bending.

[0037] It should be noted that the vacuum adsorption device 500 in this embodiment is conventional prior art in the field and will not be described in detail here.

[0038] Furthermore, the support 100 is also provided with a slide rail 600 for the vacuum adsorption device 500 to slide. The vacuum adsorption device 500 slides along the length of the slide rail 600 to adjust the position of the vacuum adsorption device 500 relative to the steel roll. In other words, by adjusting the position of the vacuum adsorption device 500, the steel roll can be located at the front end of the steel roll during the transmission process, so that the steel roll is in a straight state during the transmission process.

[0039] In addition, to ensure the stability of the steel sheet roll during transmission, the stripping system also includes a counterweight device 700. The counterweight device 700 is used to apply pressure to the vacuum adsorption device 500, so that when the vacuum adsorption device 500 adsorbs the steel sheet roll, the vacuum adsorption device 500 applies a tensile force in the opposite transmission direction to the steel sheet roll, thereby straightening the steel sheet roll. Specifically, in some embodiments, the counterweight device 700 includes a counterweight block 710, a flexible connector 720, and at least one steering member 730. The steering member 730 is disposed on the connector. One end of the flexible connector 720 is connected to the counterweight block 710, and the other end is connected to the vacuum adsorption device 500 after being turned by the steering member 730, so that the counterweight block 710 applies a tensile force to the vacuum adsorption device 500.

[0040] It should be noted that the flexible connector 720 can be made from ropes using existing technology.

[0041] In some other embodiments, multiple steering components 730 are provided, and the multiple steering components 730 are staggered on the bracket 100, so that the flexible connector 720 is connected to the vacuum adsorption device 500 after multiple steering.

[0042] Furthermore, the support frame 100 includes a support frame 110 and a material rack 120 rotatably connected to the support frame 110;

[0043] Specifically, the conveying device 200, the detection device 300, the peeling device 400, and the vacuum adsorption device 500 are all mounted on the support frame 110, and the steel sheet roll is mounted on the material rack 120.

[0044] Specifically, in this embodiment, the support 100 includes a support frame 110 and a material rack 120 rotatably connected to the support frame 110. The conveying device 200, the detection device 300, and the peeling device 400 are all mounted on the support frame 110, and the steel sheet is rolled on the material rack 120.

[0045] Specifically, the transmission device 200 includes multiple drive rollers and telescopic components 2100. The multiple drive rollers are all mounted on the support 100 to transmit the steel sheet rolls.

[0046] Among them, at least two drive rollers are arranged opposite each other on the multiple drive rollers, and one of the two drive rollers arranged opposite each other is connected to the telescopic member 2100. The telescopic member 2100 drives one drive roller to telescopically move, thereby adjusting the distance between the two drive rollers arranged opposite each other, so as to compact part of the steel sheet roll.

[0047] The telescopic component 2100 is located at the end of the steel sheet roll transport path.

[0048] Please see Figure 1 As shown, to facilitate understanding of this case, the transmission path of the steel sheet coil is explained by way of example. The transmission device 200 includes a first transmission roller 210, a second transmission roller 220, a third transmission roller 230, a fourth transmission roller 240, a fifth transmission roller 250, a sixth transmission roller 260, a seventh transmission roller 270, an eighth transmission roller 280, and a ninth transmission roller 290.

[0049] First, the steel strip coil needs to be installed on the material rack 120. The sequence of the feeding action is as follows: the steel strip first comes down from the material rack 120 and passes through the first drive roller 210, the detection device 300 and then reaches the vacuum adsorption device 500. Then the steel strip passes through the second drive roller 220 and reaches the stripping plate 410. Then the steel strip passes around the third drive roller 230 and the fourth drive roller 240, as well as the fifth drive roller 250 and the sixth drive roller 260, and reaches between the seventh drive roller 270 and the eighth drive roller 280. Finally, the steel strip passes through the seventh drive roller 270 and the eighth drive roller 280 and is wound onto the ninth drive roller 290.

[0050] It should be noted that the telescopic component 2100 is connected to the eighth transmission roller 280, and the seventh transmission roller 270 and the eighth transmission roller 280 are arranged opposite to each other. The telescopic component 2100 can be a cylinder. By controlling the movement of the telescopic component 2100, the eighth transmission roller 280 is pushed to press the steel strip between the seventh transmission roller 270.

[0051] In summary, the steel sheet stripping system of one embodiment of this invention has at least the following advantages compared to the existing steel sheet stripping methods:

[0052] In the steel sheet roll peeling system provided by the present invention, a peeling device 400 is provided on the support 100. The peeling device 400 includes a peeling plate 410 movably connected to the support 100. By adjusting the tilt angle of the peeling plate 410, at least one edge of the peeling plate 410 abuts against a portion of the steel sheet roll. That is, by utilizing the material characteristic that the steel sheet itself has a certain hardness, adjusting the angle of the peeling plate 410 can cause a portion of the steel sheet on the steel sheet roll to be lifted off the roll during the transmission process. Subsequently, the suction nozzle 430 on the telescopic suction machine 420 in the peeling device 400 performs a telescopic movement, thereby allowing the remaining steel sheet to be lifted off the roll. After a portion of the steel sheet is lifted up using the edge of the peeling plate 410 as a fulcrum, the suction nozzle 430 adsorbs the two lifted portions of the steel sheet to completely peel the steel sheet off the steel sheet roll. Compared with the direct vacuum suction method in the prior art, this invention first uses the inclined peeling plate 410 to lift up two parts of the steel sheet during the transport of the steel sheet roll, and then uses the suction nozzle 430 to pick it up. This achieves the peeling process of the steel sheet with a smaller suction force, solving the technical problems of difficulty in peeling due to the inability to adjust the appropriate negative pressure and the unstable adhesive of the steel sheet backing in the prior art, and achieving a stable and reliable peeling effect on the steel sheet.
