[0031] In order to make the personnel in the technical field better understand the present application scheme, the present application is further described in detail below in combination with the drawings.

[0032] The relational terms such as "first" and "second" and the like are merely used to distinguish one from another of similar names, and do not necessarily require or imply there is any such actual relationship or order between the parts.

[0033] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, Figure 1 is an axial side view of the material collecting device of the electrolytic copper foil in the embodiment of the present application, rear side view angle; Figure 2 is Figure 1 a side view; Figure 3 is an axial side view of the material collecting device of the electrolytic copper foil in the embodiment of the present application, front side view angle; Figure 4 is Figure 3 an enlarged schematic view of part of the structure in

[0034] The technical scheme of the present application provides a kind of electrolytic copper foil's material receiving equipment, electrolytic copper foil's material receiving equipment includes support 3, at least two material receiving assemblies 1, support 3 is used to support material receiving assembly 1;Each material receiving assembly 1 includes cutting part 10 and roll part 11, roll part 11 is arranged in material receiving position, cutting part 10 is used to cut copper foil 4.It also includes mechanical arm (not shown in the figure), mechanical arm is used to move copper foil 4 between two roll parts 11.It also includes at least two material changing assemblies 2, two material changing assemblies 2 correspond to two material receiving assemblies 1 one by one adaptation.Each material changing assembly 2 includes first driving part 21 and guide part 22, guide part 22 is connected with support 3, guide part 22 has first end 221 and end 222, end 222 is provided with material receiving position, under the action of first driving part 21, roll part 11 can move between first end 221 and end 222.

[0035] In actual operation process, two material receiving assemblies 1 can alternate work.After the roll part 11 of one material receiving assembly 1 is completed, after cutting copper foil 4 using cutting part 10, mechanical arm moves copper foil 4 to the roll part 11 of another material receiving assembly 1.The roll part 11 of another material receiving assembly 1 starts to run, so as to continue to roll copper foil 4.The roll part 11 stops running after rolling is completed, and the first driving part 21 drives the roll part 11 to the first end 221 from the end 222 of the guide part 22, and then the mechanical arm transfers the roll part 11 to the next process.The mechanical arm places the new roll part 11 at the first end 221 of the guide part 22, and the first driving part 21 pushes the new roll part 11 to the material receiving position at the end 222, waiting for the subsequent rolling of copper foil 4.The above operation is repeated, so that two material receiving assemblies 1 can alternate work to complete continuous rolling of copper foil 4 produced by the foil machine, and the production efficiency of copper foil 4 is improved.

[0036] In an optional example, the first driving part 21 includes a first driving unit, a screw connected with the first driving unit, two ball slides matched with the screw, and a push block provided on the ball slide and capable of abutting against the shaft 112 of the roll part 11 in the axial direction.The screw extends in the same direction as the guide part 22, and the roll part 11 is located between the two push blocks.In this way, the first driving part 21 can drive the roll part 11 to move along the extension direction of the guide part 22.

[0037] As a specific example, the guide part 22 is provided with a guide groove, and part of the roll part 11 can be located in the guide groove and move along the extension direction of the guide part 22 along the guide groove.Specifically, the bearing 112b provided on the roll part 11 can be located in the guide groove, and the two groove walls of the guide groove form a stop in the axial direction of the bearing 112b, and the bearing 112b can roll or slide relative to the guide groove.

[0038] Please continue to see Figures 1 to 3The two material receiving assemblies 1 are arranged above and below the height direction of the support 3. The two material receiving assemblies 1 are defined as a first material receiving assembly 1a and a second material receiving assembly 1b, respectively, and the first material receiving assembly 1a is arranged above the second material receiving assembly 1b.

[0039] The first material receiving assembly 1a comprises a first roller part 11a, and the second material receiving assembly 1b comprises a second roller part 11b. The first roller part 11a is arranged above the second roller part 11b. In this way, when the copper foil 4 is moved between the two material receiving assemblies 1, the robot only needs to move up and down, which simplifies the moving path of the robot.

[0040] In another optional embodiment, as shown in Figure 2 , the first roller part 11a has a first feeding side 11a-1, and the second roller part 11b has a second feeding side 11b-1. The first feeding side 11a-1 is arranged on the side of the first roller part 11a close to the second roller part 11b, and the second feeding side 11b-1 is arranged on the side of the second roller part 11b close to the first roller part 11a.

[0041] In a specific embodiment, the discharge end of the foil production machine is arranged on the right side of the material receiving device of the electrolytic copper foil. The first feeding side 11a-1 is arranged on the side of the first roller part 11a close to the bottom, and the second feeding side 11b-1 is arranged on the side of the second roller part 11b close to the top. In this way, the feeding sides of the two roller parts 11 are close to each other in the height direction.

[0042] In the present embodiment, the rotation directions of the first roller part 11a and the second roller part 11b are opposite, and the specific rotation directions are set with reference to the position of the foil production machine. For example, when the foil production machine is arranged on the right side in the figure, the first roller part 11a rotates in the clockwise direction in the figure, and the second roller part 11b rotates in the counterclockwise direction in the figure; conversely, when the foil production machine is arranged on the left side in the figure, the first roller part 11a can rotate in the counterclockwise direction, and the second roller part 11b can rotate in the clockwise direction.

[0043] In this way, the distance and time of the robot moving in the height direction can be reduced, and the material receiving efficiency is further improved.

[0044] Please refer to Figure 1 and Figure 2 , in some other embodiments in the present application, the first material receiving assembly 1a comprises a first cutting part 10a, and the second material receiving assembly 1b comprises a second cutting part 10b. As shown in Figure 1 , the first cutting part 10a and the second cutting part 10b are both provided with a cutter body (not shown in the figure) which can move axially along the roller part 11.

[0045] Specifically, the cutting part 10 comprises a slide cylinder 10a-1 and a support block 10a-2 for supporting the cutter body, the slide cylinder 10a-1 is capable of driving the support block 10a-2 to move reciprocally along the axial direction of the roller part 11, so as to drive the cutter body arranged on the support block 10a-2 to move reciprocally along the axial direction.

[0046] The first roller part 11a has a first feeding path 11a-2, the second roller part 11b has a second feeding path 11b-2, the cutter body of the first cutting part 10a is arranged towards the first feeding path 11a-2, and the cutter body of the second cutting part 10b is arranged towards the second feeding path 11b-2.

[0047] In actual operation, the first cutting part 10a and the second cutting part 10b need to avoid the first feeding path 11a-2 and the second feeding path 11b-2, so as to avoid interfering with the copper foil 4.

[0048] In the example as shown in the figure, the first feeding path 11a-2 is located on the upper side of the second feeding path 11b-2. The copper foil 4 passes through the discharge end of the foil machine, and is wound along the first feeding path 11a-2 with the first roller part 11a. Alternatively, the copper foil 4 passes through the discharge end of the foil machine, and is wound along the second feeding path 11b-2 with the second roller part 11b. After the corresponding roller part 11 completes the winding, the corresponding cutting part 10 is used to cut the copper foil 4.

[0049] Specifically, after the first roller part 11a completes the winding, the mechanical arm clamps both sides of the copper foil 4 in the width direction. The first cutting part 10a starts to operate to cut the copper foil 4. Then the mechanical arm drives the copper foil 4 to move downward to the second feeding side 11b-1, and the second roller part 11b continues to wind the copper foil 4.

[0050] In a specific example, the cutting part 10 further integrates an electromagnetic valve switch, and the cutter body adopts a special alloy blade, so as to complete the cutting operation of the copper foil 4 within 0.5 seconds.

[0051] In this way, the traditional manual cutting mode can be replaced, and the material collection efficiency is further improved.

[0052] In the above various embodiments, as shown in Figure 1 , Figure 4 and Figure 5 , Figure 5 is a partial structure enlarged view of Figure 1 . The material collection assembly 1 further comprises a locking piece 23 arranged on the support 3, the locking piece 23 can be switched between an open position and a closed position; in the closed position, the locking piece 23 can limit the roller part 11 in the material collection position. In this way, the position deviation of the roller part 11 from the support 3 during the winding process can be avoided.

[0053] In one specific embodiment, as shown in Figure 4 、 Figure 5 and Figure 6 , Figure 6 is a structural schematic diagram of the material receiving assembly in the embodiment of the present application. The roller part 11 comprises a roller body 111 and a rotating shaft 112 connected with the roller body 111, and the rotating shaft 112 is arranged at both ends of the roller body 111. The rotating shaft 112 is sleeved with a bearing 112b, and the inner ring of the bearing 112b is circumferentially stopped with the rotating shaft 112 to form a rotation.

[0054] The locking part 23 comprises a rotating arm 231 which is generally in a u-shaped structure. In the locking position, part of the bearing 112b is located in the rotating arm 231. One end of the rotating arm 231 is directly or indirectly hinged with the support 3. The rotating arm 231 can rotate around the rotating axis parallel to the support 3 to switch between the open position and the closed position. In the open position, the locking part 23 forms an opening for the bearing 112b to enter on the side of the guide part 22.

[0055] The other end of the rotating arm 231 is provided with a locking bolt 232 which can move along the radial direction of the bearing 112b. In the closed position, the locking bolt 232 presses the outer ring of the bearing 112b against part of the wall of the rotating arm 231 along the radial direction of the bearing 112b. Thus, in the closed position, the bearing 112b can be clamped between the rotating arm 231 and the locking bolt 232 in a direction generally parallel to the support 3, so that the roller part 11 can be locked while the roller part 11 can rotate relative to the support 3.

[0056] Of course, in addition to the structure of the locking part 23 in the present embodiment, those skilled in the art can also use other structures of the locking part 23, which can be selected by those skilled in the art as needed.

[0057] The way in which the roller part 11 can rotate relative to the support 3 will be described below.

[0058] As shown in Figure 1 and Figure 6 , each material receiving assembly 1 comprises a second driving part 12 which comprises a transmission part 121 capable of moving along the axial direction of the roller part 11 between the locking position and the disengaging position. The end of each rotating shaft 112 is further provided with an adapter 112a. In the disengaging position, the transmission part 121 is disengaged from the adapter 112a. In the locking position, the transmission part 121 forms circumferential rotation with the adapter 112a.

[0059] Specifically, the transmission part 121 rotates with the power output shaft 122 of the second driving part 12, and the transmission part 121 can also move along the axial direction of the power output shaft 122 to be inserted into the adapter 112a to form circumferential rotation, or to be away from the adapter 112a.

[0060] In the specific operation process, when the new roller part 11 needs to be replaced, the locking part 23 is first operated to the open position, and at the same time, the second driving part 12 needs to be operated to disengage the transmission part 121 from the adapter part 112a. At this time, the completed roller part 11 can be moved along the guide part 22.

[0061] Conversely, when the new roller part 11 moves to the end 222 of the guide part 22, the second driving part 12 is operated to move the transmission part 121 axially and engage with the adapter part 112a to complete the circumferential rotation stop, and at the same time, the locking part 23 is operated to the closed position to lock the new roller part 11 in the material collecting position.

[0062] In one example, the bearing 112b is axially located between the adapter part 112a and the roller body 111. In this way, the roller part 11 can be connected to the second driving part 12 while being locked in the material collecting position.

[0063] In one example, one of the transmission part 121 and the adapter part 112a is a gear, and the other is a tooth sleeve capable of accommodating the gear, and the gear can be engaged with the inner wall of the tooth sleeve to form a circumferential rotation stop.

[0064] In one specific example, as shown in Figure 6 The transmission part 121 is sleeved on the outside of the power output shaft 122 and connected with the power output shaft 122 through the key 123 extending in the axial direction. The transmission part 121 and the power output shaft are connected through the key 123 to realize rotation with the power output shaft 122 while extending in the axial direction of the power output shaft 122.

[0065] In other embodiments, the driving mode of the transmission part 121 moving in the axial direction is further described.

[0066] As shown in Figure 4 and Figure 6 The material collecting equipment of the electrolytic copper foil further comprises a third driving part 13 in transmission connection with the transmission part 121 to drive the transmission part 121 to move in the axial direction of the power output shaft 122 to the disengagement position and the locking position.

[0067] Specifically, the third driving part 13 comprises an operating end 131 hinged to the support 3, which can rotate around a first rotation axis perpendicular to the support 3. The operating end 131 is further hinged with a roller 132, which can rotate around a second rotation axis perpendicular to the support 3, and the first rotation axis and the second rotation axis are arranged in a spaced manner.

[0068] The side of the transmission part 121 away from the adapter part 112a is provided with a groove around the power output shaft 122, and the roller 132 is located in the groove.

[0069] The driving operation end 131 drives the roller 132 to move axially, and the roller 132 can also move radially relative to the power output shaft 122. In the movement of the roller 132, the roller 132 can abut against the groove wall, and in the abutting process, the transmission member 121 can be driven to move axially. Such a structure can realize the axial movement of the transmission member 121 while reducing the cost of the equipment.

[0070] The principles and implementation manners of the present application are described by using specific examples in the present application, and the above examples are only used to help understand the core idea of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
