[0035] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The utility model provides an embodiment of a coil material preprocessing device, including a frame 7, a reeling mechanism (not shown in the figure) and a coil material label tearing mechanism arranged on the frame 7, the reeling mechanism is located on one side of the frame 7, the foil coil material is placed on the reeling mechanism, and the reeling mechanism is used to reel the coil material.

[0037] Specifically, the roll label tearing mechanism includes a positioning component 1, a support base 2, a linear guide rail 3 arranged on the support base 2 and a transverse movement component 5. The support base 2 is arranged on the frame, and the length direction of the linear guide rail 3 extends along the axial direction of the roll material. A plurality of adsorption components 4 are slidably connected to the linear guide rail 3. The positioning component 1 is used to locate the positions of a plurality of labels on the roll material, the adsorption component 4 is used to adsorb the labels on the roll material, and the transverse movement component 5 is used to drive the adsorption component 4 to move along the axial direction of the roll material.

[0038] Specifically, the transverse movement assembly 5 includes a linear module 51, a base plate 52 arranged on the linear module 51, and a plurality of clutches 53 arranged on the base plate 52. The linear module 51 is arranged on the support seat 2. The length direction of the linear module 51 is the same as the length direction of the linear guide rail 3. The plurality of clutches 53 are respectively used to lock or release a plurality of adsorption assemblies 4.

[0039] The clutch 53 includes a top block 531 and a first power member 532 . The first power member 532 is disposed on the bottom plate 52 . The top block 531 is disposed on the first power member 532 . The first power member 532 is used to drive the top block 531 to lock or release the adsorption component 4 .

[0040] Furthermore, the first power member 532 is a first cylinder, and the top block 531 is arranged at the telescopic end of the first cylinder.

[0041] More specifically, the adsorption assembly 4 includes a bracket 41, a second power member 42 and a suction cup 43. The bracket 41 is slidably connected to the linear guide rail 3, the second power member 42 is arranged on the bracket 41, and the suction cup 43 is arranged on the second power member 42. The second power member 42 is used to drive the suction cup 43 to approach or move away from the coil, and the first power member 532 is used to drive the top block 531 to lock or release the bracket 41.

[0042] Furthermore, the linear guide 3 includes a slide rail 32 and a plurality of sliders 31 , the sliders 31 are slidably connected to the slide rail 32 , the bracket 41 is disposed on the slider 31 , and a fixing member is disposed on the slider 31 , and the fixing member is used to fix the slider 31 to or release the slide rail 32 .

[0043] When the first power member 532 drives the top block 531 to release the bracket 41, the fixing member fixes the slider 31 on the slide rail, thereby fixing the bracket 41 to prevent the bracket 41 from shifting and ensuring that the suction cup 43 is accurately aligned with the label.

[0044] Specifically, the fixing member is an airbag. When the airbag is inflated, the airbag expands and squeezes the slide rail 32 to fix the slider 31 on the slide rail 32. When the airbag is deflated, the airbag shrinks and releases the slide rail 32 to allow the slider 31 to be slidably connected to the slide rail 32.

[0045] Furthermore, the second power member 42 is a second cylinder, and the suction cup 43 is arranged at the telescopic end of the second cylinder.

[0046] During operation, the positioning component 1 identifies and locates a plurality of labels on the coil, and the positioning component 1 transmits data to the transverse movement component 5. The plurality of first power members 532 respectively drive the top block 531 to press the bracket 41 tightly, so that the bracket 41 is connected to the bottom plate 52. The linear module 51 drives the bottom plate 52 and the plurality of clutches 53 to move along the axial direction of the coil, and then drives the plurality of adsorption components 4 to slide along the length direction of the linear guide 3. According to the label positions detected by the positioning component 1, the plurality of adsorption components 4 are moved to the positions corresponding to the plurality of labels in turn. Whenever an adsorption component 4 corresponds to the position of a label, the corresponding first power member 532 drives the top block 531 to press the bracket 41 tightly, so that the bracket 41 is connected to the bottom plate 52. The linear module 51 drives the bottom plate 52 and the plurality of clutches 53 to move along the axial direction of the coil, and then drives the plurality of adsorption components 4 to slide along the length direction of the linear guide 3. Component 532 drives top block 531 to release the corresponding bracket 41. At the same time, the air bag on the slider 31 corresponding to the bracket 41 is inflated to fix the slider 31 on the slide rail 32 to prevent the bracket 41 from shifting, so that each suction cup 43 corresponds to each label on the roll in turn. Then, the second power component 42 on the bracket 41 drives the suction cup 43 to approach the corresponding label, so that the suction cup 43 sucks the corresponding label. Then, the reel of the unwinding mechanism drives the roll to rotate. At the same time, several second power components 42 respectively drive several suction cups 43 to move away from the roll at the same time, so that several labels can be torn off the roll at the same time, thereby improving work efficiency.

[0047] Reference Figure 3 In some preferred embodiments, a push plate 54 is further provided on the bottom plate 52. The push plate 54 is located on one side of the clutch 53. The push plate 54 extends to one side of the adsorption component 4. After a number of labels are torn off the roll, the linear module 51 drives the push plate 54 to move in the opposite direction. The push plate 54 moves a number of adsorption components 4 on the linear guide rail 3 to a standby position on one side. There is no need for a number of clutches 53 on the bottom plate 52 to align a number of adsorption components 4 on the linear guide rail 3 one by one, thereby further improving work efficiency.

[0048] Reference Figure 4 In some preferred embodiments, the top block 531 is a conical block, and the bracket 41 is provided with a conical hole 411. When the clutch 53 moves to a position corresponding to the bracket 41, the second power member 42 drives the conical block to insert into the conical hole 411. The conical hole 411 has a guiding effect on the conical block, thereby ensuring that the position of the adsorption component 4 is aligned with the position of the clutch 53, and then ensuring that the suction cup 43 can be aligned with the label on the roll.

[0049] Furthermore, a photoelectric baffle 55 is also provided on the bottom plate 52, and a groove-type photoelectric sensor 44 is provided on one side of the plurality of brackets 41. When the second power member 42 drives the conical block to insert into the conical hole 411, the groove-type photoelectric sensor 44 corresponds to the photoelectric baffle 55, and the linear module 51 drives the bottom plate 52 to move, thereby driving the bracket 41 to move to the position of the label. Then, the second power member 42 drives the conical block to exit the conical hole 411, so that the clutch 53 is separated from the adsorption component 4, and then, the linear module 51 drives the bottom plate 52 to continue to move. At this time, the groove-type photoelectric sensor 44 on the bracket 41 is separated from the photoelectric baffle 55, and the groove-type photoelectric sensor 44 receives a signal change. If the groove-type photoelectric sensor 44 does not receive a signal change, the clutch 53 and the adsorption component 4 are at corresponding positions, thereby being able to detect whether the clutch 53 is separated from the adsorption component 4, further ensuring that the suction cup 43 in the adsorption component 4 can be aligned with the label on the roll.

[0050] Reference Figure 2 In some preferred embodiments, the positioning component 1 includes a CCD visual detector 11 and a color mark sensor 12. The CCD visual detector 11 is used to identify the position of the label on the coil, and the color mark sensor 12 is used to identify the edge of the foil material head of the calibration coil. The CCD visual detector 11 can be fixed on the top of the coil by a fixing frame (not shown in the figure), and the color mark sensor 12 is fixed on the bottom plate 52 by a fixing seat 121. When the CCD visual detector 11 identifies the position of the label on the coil, the lateral movement component 5 drives the plurality of adsorption components 4 to move to the plurality of The label is at the corresponding position on the axial direction of the coil, and then the reel of the unwinding mechanism drives the coil to rotate. When the color mark sensor 12 identifies the position of the edge of the foil material head of the coil, the color mark sensor 12 transmits a signal to the unwinding mechanism, and the reel of the unwinding mechanism stops rotating, so that the several suction cups 43 in the adsorption component 4 correspond to the several labels on the coil one by one, thereby accurately identifying the position of the label on the coil, and providing sufficient preparation time for the several suction cup 43 components to move to the corresponding positions of the several labels on the axial direction of the coil, thereby improving work efficiency.

[0051] Furthermore, it also includes a belt pressing assembly 6, which is arranged on the support seat 2 and located above the linear guide rail 3. The belt pressing assembly 6 is used to press the foil material head of the coil, thereby preventing the foil material from unrolling after the label is torn off.

[0052] Furthermore, the belt pressing assembly 6 includes a pressing roller 61 and a third power member 62. The axial direction of the pressing roller 61 is the same as the axial direction of the coil. The third power member 62 is arranged on the support seat 2. The third power member 62 is used to drive the pressing roller 61 to approach or move away from the coil.

[0053] Reference Figure 2 , Figure 5 and Figure 7 Specifically, there are two third power members 62, which are third cylinders. An adapter plate 63 is provided at the telescopic end of the third cylinder. A bearing fixing seat 64 and a self-aligning ball bearing 65 are provided on the adapter plate 63. An oil nozzle 66 is provided on the bearing fixing seat 64. The oil nozzle 66 provides lubricating oil for the self-aligning ball bearing 65. The two ends of the pressure roller 61 are respectively sleeved on the inner rings of the two self-aligning ball bearings 65. The two ends of the pressure roller 61 are respectively rotatably connected to the two adapter plates 63. The self-aligning ball bearings 65 can compensate for the errors caused by eccentricity and shaft deflection. When the pressure roller 61 is pressed on the surface of the coil, the coil drives the pressure roller 61 to rotate in the opposite direction, thereby ensuring the normal rotation of the coil.

[0054] More specifically, the pressure roller 61 is an anti-sticking rubber roller, which can prevent the adhesive material on the coil from adhering to the surface of the pressure roller 61 .
