[0055] In order to make the technical problems to be solved, technical solutions and beneficial effects of the present application more clearly understood, the following will be further described in detail in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0056] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0057] It should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0058] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0059] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the following will be further described in detail in conjunction with the drawings and embodiments.

[0060] Please also refer to Figure 2 and Figure 3 This embodiment provides an automatic coil material feeder, including a material receiving and unloading module 1 and a material stripping module 2.

[0061] The following is a detailed description of the material receiving and unloading module 1 in conjunction with the accompanying drawings:

[0062] See also Figure 7 The material receiving and unloading module 1 includes an installation base plate 11, a material unloading mechanism 12 and two material receiving mechanisms 13. The material unloading mechanism 12 and the two material receiving mechanisms 13 are respectively detachably connected to the installation base plate 11. The material unloading mechanism 12 is used to realize the unwinding of the roll material 9. One of the material receiving mechanisms 13 is used to collect the cover tape 91, and the other material receiving mechanism 13 is used to collect the bottom paper 93.

[0063] Please also refer to Figure 7 and Figure 8 The unloading mechanism 12 includes a fixed shaft 121, a unloading shaft core 122 and a damper 123, wherein the fixed shaft 121 is fixed on the mounting base plate 11, the unloading shaft core 122 is sleeved on the outer wall of the fixed shaft 121, and the unloading shaft core 122 is rotatably connected to the fixed shaft 121 through a bearing. The unloading shaft core 122 is used to install the coil 9, and the damper 123 is used to connect the unloading shaft core 122 and the fixed shaft 121, so that the unloading shaft core 122 has a certain damping when rotating relative to the fixed shaft 121, thereby preventing the unloading shaft core 122 from causing the coil 9 to be discharged outward in advance due to inertia, that is, when the coil 9 is just discharged out, it can always maintain a certain tension with the unreleased part.

[0064] Please refer to the Figure 7 and Figure 8 The unloading mechanism 12 also includes a first baffle 124 and a second baffle 125. The first baffle 124 is fixed to the first end surface of one side of the unloading shaft core 122, and the second baffle 125 is fixed to the second end surface of the other side of the unloading shaft core 122. In actual use, the second baffle 125 can be removed, and the used coil 9 on the unloading shaft core 122 can be pulled outward along the axis of the unloading shaft core 122. The center hole of the new coil 9 is then inserted and fixed to the unloading shaft core 122. It is best to reinstall the second baffle 125 on one side of the unloading shaft core 122. The first baffle 124 and the second baffle 125 are used to limit the position of the coil 9, preventing the coil 9 from sliding out to the ends during unloading, thereby ensuring the reliability of the unloading operation.

[0065] Please also refer to Figure 8 and Figure 9The damper 123 includes a fixed member 1231, a rotating member 1232, a rotating shaft 1233, a butterfly spring 1234, and an adjusting nut 1235. The fixed member 1231 is fixed to the rotating shaft 1233. The rotating member 1232 and the butterfly spring 1234 are mounted together on the rotating shaft 1233. The rotating member 1232 can rotate along the outer wall of the rotating shaft 1233. The adjusting nut 1235 is threadedly connected to the rotating shaft 1233 and screwed onto the end of the rotating shaft 1233. When the adjusting nut 1235 abuts the butterfly spring 1234, the adjusting nut 1235 and the fixed member 1231 jointly clamp the butterfly spring 1234 and the rotating member 1232. The adjusting nut 1235 adjusts the resistance to relative rotation between the rotating member 1232 and the fixed member 1231 by changing the compression of the butterfly spring 1234, thus facilitating damping adjustment. The fixing member 1231 is fixed to the fixed shaft 121 , and the rotating member 1232 is fixed to the discharge shaft core 122 , so that the discharge shaft core 122 has a certain damping when rotating relative to the fixed shaft 121 .

[0066] Please refer to the Figure 8 and Figure 9 Preferably, the discharge mechanism 12 further includes an end cap 126 and a fastener 127. The second baffle 125 is provided with a through-hole 1251 to expose a portion of the end face of the discharge shaft core 122. At least a portion of the end cap 126 is inserted into the through-hole 1251. Furthermore, the end cap 126 connects the end face of the discharge shaft core 122 and the rotating member 1232. Specifically, the end cap 126 includes a main body 1261 and a raised portion 1262 connected to each other. The raised portion 1262 is provided with a limiting groove 12621 on the end face facing away from the main body 1261. The rotating member 1232 is inserted into the limiting groove 12621. The fastener 127 is a hand screw. The fastener 127 is screwed to the second baffle 125 and abuts against the outer wall of the raised portion 1262, so that the fastener 127, the end cap 126, and the second baffle 125 are connected as a whole. In addition, the end cover 126 is further provided with a raised positioning portion 1263 on the main body 1261 , and the positioning portion 1263 is inserted into the end surface of the discharge shaft core 122 , so that the end cover 126 and the discharge shaft core 122 are connected as one body.

[0067] Please also refer to Figure 7 and Figure 10The material collecting mechanism 13 comprises a middle shaft 131, a driver 132, a material collecting shaft core 133 and a ring 134. The middle shaft 131 and the driver 132 are both mounted on the mounting base plate 11. The middle part of the material collecting shaft core 133 is provided with a middle hole 1331. The middle shaft 131 is arranged in the middle hole 1331 and is rotatably connected with the material collecting shaft core 133 through a bearing. The central axis of the middle shaft 131 and the central axis of the material collecting shaft core 133 are both parallel to the central axis of the material feeding shaft core 122. The driver 132 is connected with the material collecting shaft core 133. The driver 132 is used to drive the material collecting shaft core 133 to rotate relative to the middle shaft 131. The ring 134 is an O-shaped rubber ring. The ring 134 is sleeved on the outer wall of the middle shaft 131 and abuts against the hole wall of the middle hole 1331 of the material collecting shaft core 133. When the material collecting shaft core 133 rotates relative to the middle shaft 131, the ring 134 can provide certain damping. In this way, the inertia of the material collecting shaft core 133 is not too large. The phenomenon that the cover tape 91 or the base paper 93 is pulled and broken can be avoided.

[0068] Please refer to Figure 7 and Figure 10 again. As preferred, the driver 132 comprises a gear motor 1321 and a transmission gear 1322. The gear motor 1321 is mounted on the mounting base plate 11. The transmission gear 1322 is sleeved on the material collecting shaft core 133. The gear motor 1321 and the transmission gear 1322 are in meshing transmission. When the gear motor 1321 is in a working state, the transmission gear 1322 will drive the material collecting shaft core 133 to rotate.

[0069] Please refer to Figure 7 and Figure 10 again. As preferred, the material collecting mechanism 13 further comprises a clamping rod 135. The clamping rod 135 comprises a plug-in part 1351, a bending part 1352 and a clamping part 1353 which are sequentially connected. The outer wall of the material collecting shaft core 133 is provided with a clamping groove 1332. The extending direction of the clamping groove 1332 is parallel to the central axis of the material collecting shaft core 133. The end surface of the material collecting shaft core 133 is provided with a mounting hole 1333. In use, the clamping rod 135 is taken out first. Then one end of the cover tape 91 or the base paper 93 on the roll material 9 is manually wound on the material collecting shaft core 133. After winding, the plug-in part 1351 of the clamping rod 135 is plugged into the mounting hole 1333. At the same time, the clamping part 1353 is plugged into the clamping groove 1332. At this time, the clamping part 1353 abuts against the groove wall of the clamping groove 1332 under the elastic force of the bending part 1352. The clamping part 1353 and the groove wall of the clamping groove 1332 jointly clamp the cover tape 91 or the base paper 93. In this way, one end of the cover tape 91 or the base paper 93 can be stably arranged on the material collecting shaft core 133. When the driver 132 drives the material collecting shaft core 133 to rotate, the material collecting shaft core 133 can receive the cover tape 91 or the base paper 93 in a winding manner.

[0070] The stripping module 2 is described in detail below with reference to the accompanying drawings:

[0071] Please also refer to Figure 3 and Figure 4 The stripping module 2 includes a mounting base 21, a stripping knife mechanism 22 and a pulling module 23. The stripping knife mechanism 22 and the pulling module 23 are detachably connected to the mounting base 21 respectively. In addition, the mounting base 21 and the above-mentioned mounting substrate 11 are detachably connected.

[0072] Please also refer to Figure 4 and Figure 5 The mounting base 21 includes a mounting side plate 211, a mounting bottom plate 212, a connecting plate 213, and an adsorption member 214. The mounting side plate 211 is fixed to one side of the mounting bottom plate 212, the connecting plate 213 connects the mounting bottom plate 212 and the mounting side plate 211, and two guide rails 215 are mounted on the mounting side plate 211. The length directions of the two guide rails 215 are parallel to the first direction (i.e., the X-axis direction). The adsorption member 214 is connected to the connecting plate 213, and the top surface of the adsorption member 214 is provided with an adsorption surface 2141.

[0073] Please also refer to Figure 3 、 Figure 4 、 Figure 11 and Figure 16 The peeling mechanism 22 is arranged between the adsorption surface 2141 and the material receiving and unloading module 1. The peeling mechanism 22 has a supporting top surface 226 for carrying the bottom paper 93 and the material 92, so that the bottom paper 93 and the material 92 can be transported together along the positive direction of the X-axis.

[0074] Specifically, the stripping mechanism 22 includes a base 221, a stripping blade 222, a stripping rod 223, a motor 224, and a rotating gear (not shown). The base 221 is slidably connected to the two guide rails 215 and can move linearly along the guide rails 215 in the positive or negative direction of the X-axis. The stripping blade 222 is mounted on the end of the base 221 near the suction surface 2141. The support top surface 226 includes the top surface of the stripping blade 222 and the top surface of the base 221. The end of the stripping blade 222 near the suction surface 2141 is provided with an inclined surface 2221, which is inclined downward and away from the suction surface 2141. The stripping rod 223 is mounted on the base 221 via a bearing and is located below the stripping blade 222. The stripping rod 223 is rotatable relative to the base 221 and is used to pull a portion of the backing paper 93. The motor 224 is fixed to the base 221, and the rotating gear is fixed to the output shaft of the motor 224. In addition, a rack 218 is also fixed to the mounting side plate 211. The length direction of the rack 218 is parallel to the X-axis direction. The rack 218 is located above the rotating gear to prevent dust from accumulating on the rack 218 due to gravity. The rack 218 and the rotating gear are meshed for transmission. During operation, the output shaft of the motor 224 rotates, and the rotating gear moves along the length direction of the rack 218, that is, the peeling mechanism 22 moves as a whole along the positive direction or reverse direction of the X-axis. When the peeling mechanism 22 moves along the positive direction of the X-axis to the position closest to the adsorption surface 2141, it is defined as the first position of the peeling mechanism 22. When the peeling mechanism 22 moves along the reverse direction of the X-axis to the position farthest from the adsorption surface 2141, it is defined as the second position of the peeling mechanism 22. Figures 2 to 3 These are all structural diagrams when the peeling knife mechanism 22 is in the second position. Figure 16 This is a schematic diagram of the structure when the stripping knife mechanism 22 is in the first position and only the stripping knife 222 and the stripping rod 223 are shown. Moreover, when the stripping knife mechanism 22 switches between the first position and the second position, the support top surface 226 and the above-mentioned adsorption surface 2141 are always parallel, the adsorption surface 2141 is higher than the support top surface 226, and the difference between the adsorption surface 2141 and the support top surface 226 is the thickness of one base paper 93. In addition, please refer to Figure 16 When the stripping mechanism 22 is in the first position, the shortest distance D between the support top surface 226 and the suction surface 2141 along the first direction is smaller than the dimension of the material 92 in the first direction (i.e., the X-axis direction), so that a portion of the bottom surface of the material 92 can fall onto the suction surface 2141. When the stripping mechanism 22 moves from the first position to the second position, the stripping rod 223 pulls a portion of the backing paper 93 in a direction opposite to the first direction (i.e., opposite to the X-axis direction), so that the backing paper 93 can be separated from the material 92 that has fallen onto the suction surface 2141.

[0075] Please also refer to Figure 3 and Figure 5 A first wiring channel 2111 is provided on the mounting side plate 211, and a second wiring channel 2121 is provided on the mounting base plate 212. The first wiring channel 2111 and the second wiring channel 2121 are connected. A first connector 216 is installed on the connecting plate 213. The wires of the drivers 132 in the two material receiving mechanisms 13 are connected to the first connector 216 after passing through the first wiring channel 2111 and the second wiring channel 2121. At the same time, the wires on the motor 224 in the stripping mechanism 22 are also connected to the first connector 216 after passing through the first wiring channel 2111 and the second wiring channel 2121.

[0076] Please refer to the Figure 3 and Figure 5 The mounting base 21 also includes a quick-change base 217. The quick-change base 217 includes a connected quick-change bottom plate 2171 and a panel 2172. The quick-change bottom plate 2171 and the mounting bottom plate 212 are slidably connected along the X-axis, and a quick-release mechanism 2173 is connected between the quick-change bottom plate 2171 and the mounting bottom plate 212. The panel 2172 is used to install a second connector 2174. The second connector 2174 and the above-mentioned first connector 216 are plugged into each other. The panel 2172 is also used to cover the outward end surface of the connecting plate 213 and the outward side surface of the mounting side plate 211 to enhance the aesthetics of the product.

[0077] Please also refer to Figure 5 and Figure 6 The quick-release mechanism 2173 includes a mounting shaft 21731, a torsion spring 21732, and a buckle 21733. The mounting shaft 21731 is fixed to the mounting base 212, while the torsion spring 21732 and buckle 21733 are respectively mounted on the mounting shaft 21731. A slot 21711 is defined on the quick-change base 2171, and the buckle 21733 is engaged within the slot 21711 by the torsion force of the torsion spring 21732. To remove the quick-change base 2171, simply press the buckle 21733 until it is completely disengaged from the slot 21711. The quick-change base 2171 can then be pulled outward along the positive direction of the X-axis.

[0078] Please also refer to Figure 12-15 The traction module 23 includes a traction component 231 and a pressing component 232 .

[0079] Among them, the traction assembly 231 includes a mounting frame 2311, an active roller 2312 and a driving mechanism 2313. The two ends of the active roller 2312 are respectively mounted on the mounting frame 2311 through bearings to realize the rotational connection between the active roller 2312 and the mounting frame 2311. The driving mechanism 2313 connects the mounting frame 2311 and the active roller 2312. The driving mechanism 2313 is used to drive the active roller 2312 to rotate relative to the mounting frame 2311. The rotation of the active roller 2312 can pull the material belt for transportation. The active roller 2312 is a steel roller with high rigidity. Moreover, the outer wall of the active roller 2312 is provided with a mesh pattern. This pattern can increase the friction between the active roller 2312 and the material belt, so that the material belt will not slip on the active roller 2312, ensuring that the material belt can be reliably transported in the specified direction under the rotation of the active roller 2312.

[0080] In addition, the traction assembly 231 also includes at least one winding rod 2314 for winding the material. The winding rod 2314 can properly tension the base paper 93. The mounting frame 2311 includes a fixed side plate 23111, a supporting side plate 23112, and a support rod 23113. The support rod 23113 connects the fixed side plate 23111 and the supporting side plate 23112. One end of the driving roller 2312 and one end of the winding rod 2314 are respectively rotatably connected to the fixed side plate 23111, and one end of the driving roller 2312 and the other end of the winding rod 2314 are respectively rotatably connected to the supporting side plate 23112. The provision of the fixed side plate 23111 and the supporting side plate 23112 ensures that both ends of the driving roller 2312 and the winding rod 2314 are supported, preventing large radial runout of the driving roller 2312 and the winding rod 2314 during transport of the material strip.

[0081] In this embodiment, the driving mechanism 2313 preferably includes a motor 23131, a driving gear 23132 and a driven gear 23133, wherein the motor 23131 is fixed on the mounting frame 2311, the driving gear 23132 and the output shaft of the motor 23131 are fixed coaxially, the driven gear 23133 is sleeved on the end of the active roller 2312 and fixedly connected to the active roller 2312, the driven gear 23133 and the driving gear 23132 are engaged for transmission, and when the output shaft of the motor 23131 rotates, the rotation of the driving gear 23132 drives the rotation of the driven gear 23133, and then drives the rotation of the active roller 2312.

[0082] The pressing assembly 232 includes a mounting base 2321, a swing arm 2322, and a pressure roller 2323. The mounting base 2321 further includes a fixed base 23211 and a rotating shaft 23212. The rotating shaft 23212 is rotatably connected to the fixed base 23211 at both ends via bearings. The swing arm 2322 further includes an operating rod 23221 and a swing arm 23222. The operating rod 23221 is fixed to one end of the rotating shaft 23212, and the swing arm 23222 is fixed to the other end of the rotating shaft 23212, allowing both the operating rod 23221 and the swing arm 23222 to rotate relative to the fixed base 23211. The pressure roller 2323 is mounted on the operating rod 23221 at one end via a bearing, and on the swing arm 23222 at the other end via a bearing, allowing both the operating rod 23221 and the swing arm 23222 to rotate relative to the fixed base 23211.

[0083] The fixed base 23211 is provided with a blocking portion 232111 . The blocking portion 232111 is provided on a rotation path of the operating rod 23221 relative to the fixed base 23211 . The blocking portion 232111 is used to limit the rotation angle of the operating rod 23221 .

[0084] See also Figure 12 , Figure 12 The figure shows the state where the active roller 2312 and the pressure roller 2323 are not pressed against each other. At this time, there is no interaction force between the material strip and the active roller 2312, and the material strip will not be pulled and transported by the active roller 2312. Figure 13 The operating lever 23221 can be manually moved toward the active roller 2312 so that the operating lever 23221 contacts the blocking portion 232111. At this time, the active roller 2312 and the pressure roller 2323 are in a mutually pressed state. At this time, the pressure roller 2323 and the active roller 2312 jointly clamp the material strip. When the active roller 2312 rotates, the active roller 2312 can pull the material strip forward. Furthermore, because the pressure roller 2323 is exerted by the active roller 2312, the operating lever 23221 is tightly contacted with the blocking portion 232111. Therefore, when the material strip is transported, the pressure roller 2323 and the active roller 2312 are always pressed against each other, and the pressure roller 2323 will not spontaneously leave the active roller 2312. The pressure roller 2323 is a rubber roller with an elastic outer wall. When the material strip does not need to be pulled for transportation, the operating lever 23221 can be manually pulled away from the active roller 2312. At this time, the operating lever 23221 will be away from the blocking portion 232111, and the pressure roller 2323 will also return to the Figure 12 Compared with the conventional technical solution in which the pressure roller 2323 and the active roller 2312 are driven by a cylinder, the pressing effect of the pressure roller 2323 and the active roller 2312 pressed together in the technical solution of this embodiment is more reliable and has lower cost.

[0085] As a preferred embodiment of this embodiment, when the pressure roller 2323 and the active roller 2312 abut against each other and press together, the force exerted on the pressure roller 2323 by the active roller 2312 can be divided into a first component in the horizontal direction and a second component in the vertical downward direction. During assembly, the pressure assembly 232 can be assembled first, followed by the assembly of the traction assembly 231. Finally, the traction assembly 231 can be installed from top to bottom to a preset position. After the traction assembly 231 is installed, the active roller 2312 in the traction assembly 231 directly exerts a vertical downward force component on the pressure roller 2323 in the pressure assembly 232. Therefore, since the force exerted on the pressure roller 2323 by the active roller 2312 is configured to include a second component in the vertical downward direction, modular assembly of the traction assembly 231 and the pressure assembly 232 can be facilitated, providing the advantages of easy disassembly and maintenance.

[0086] Please also refer to Figure 3 and Figure 16 The automatic coil material feeder of this embodiment further includes a plurality of winding rotating rods 3, which are rotatably connected to the mounting substrate 11 or the mounting base 21.

[0087] See also Figure 16 After the cover tape 91 is passed around the first winding rotating rod 3, it is fixed on the receiving shaft core 133 of the upper receiving mechanism 13. Then, one end of the bottom paper 93 on the coil 9 is manually pulled out, so that one end of the bottom paper 93 passes around the inclined surface 2221 on the stripping knife 222 and rests on the outer wall of the stripping rod 223 facing the unloading shaft core 122. Then, the bottom paper 93 is manually passed between the active roller 2312 and the pressure roller 2323. Finally, one end of the bottom paper 93 is manually fixed on the receiving shaft core 133 of the receiving mechanism 13 below. After the initial work preparation is completed, part of the bottom paper 93 and the material 92 are in contact with the supporting top surface 226 of the stripping knife mechanism 22.

[0088] See also Figure 16, when working, the stripping knife mechanism 22 is in the first position, the stripping knife 222 is in the position closest to the adsorption surface 2141, and under the drive of the traction module 23, the coil 9 is gradually discharged from the discharge shaft core 122 in the discharge mechanism 12. At the same time, the collection shaft core 133 in the upper collection mechanism 13 is also running. The collection shaft core 133 in the upper collection mechanism 13 collects the discharged cover tape 91, and the discharged base paper 93 and material 92 will be transported along the support top surface 226 in the first direction (i.e., the positive direction of the X axis). When the material 92 comes to the adsorption surface 2141, the material 92 is sucked by the adsorption surface 2141, and then the stripping knife mechanism 22 is moved from the first position along the first direction The stripping mechanism 22 moves in the opposite direction of the X-axis (i.e., the opposite direction of the X-axis) to the second position. At this time, the stripping knife 222 and the stripping rod 223 both move in the opposite direction of the X-axis. The stripping rod 223 pulls the bottom paper 93 to move in the opposite direction of the X-axis. The bottom paper 93 will be separated from the material 92 located on the adsorption surface 2141. After the material 92 located on the adsorption surface 2141 is taken out by the external robot, the stripping knife 222 of the stripping mechanism 22 is reset from the second position to the first position, waiting for the next material 92 to arrive at the adsorption surface 2141. At the same time, the bottom paper 93 moves to the receiving mechanism 13 below under the traction of the traction module 23, and the receiving shaft core 133 of the receiving mechanism 13 below collects the bottom paper 93.

[0089] See also Figure 2 The automatic roll material feeder of this embodiment also includes a vacuum platform 4, which is mounted on the mounting base 21 and detachably connected to the mounting base 21, and the vacuum platform 4 is arranged between the stripping knife mechanism 22 and the material receiving and unloading module 1. The top surface of the vacuum platform 4 is provided with a plurality of suction holes 41, and the top surface of the vacuum platform 4 is parallel to and coplanar with the above-mentioned support top surface 226. Before the stripping knife 222 is reset from the first position to the second position, the vacuum platform 4 is used to suck part of the bottom paper 93 at the front end of the stripping knife 222 to prevent the bottom paper 93 from being greatly deviated in the Y-axis direction when the stripping rod 223 is pulled. That is, the vacuum platform 4 is used to ensure that the bottom paper 93 will not be greatly deviated in the Y-axis direction relative to the stripping knife 222 after the stripping knife 222 switches between the first position and the second position, thereby ensuring the reliability of the stripping operation.

[0090] In summary, the automatic coil feeder of this embodiment can automatically feed material 92 from coil 9 while also collecting cover tape 91 and backing paper 93, significantly improving the feeding efficiency of coil 9 and paving the way for fully automated production. Furthermore, the automatic coil feeder of this embodiment employs a modular design, offering advantages such as ease of assembly, disassembly, and maintenance.
