[0065] During the pole core press-assembly process, protective sheets are often placed on both sides of the pole core. The protective sheets are mainly used to protect the pole core from mechanical damage and ensure the stability and safety of the pole core during the assembly process.

[0066] Taking lithium-ion batteries as an example, the steps of pressing the pole core may be as follows: 1. Prepare the pole core: The pole core after winding or lamination is ready for pressing. 2. Place the protective sheet: Place the protective sheet on both sides of the pole core. 3. Position the pole core: Place the pole core with the protective sheet in the fixture and use the first and second limit parts of the fixture to position it. 4. Pressing: Use a pressing mechanism (such as a flattening piece) to press the pole core and the protective sheet from above to fix them in the correct position.

[0067] After the press-fitting is completed, the protection sheet can be removed from the pole core, so that the protection sheet can be reused.

[0068] In the related art, the equipment for removing the protection sheet has a complex structure, and the removal efficiency of the protection sheet is not high.

[0069] Based on this, the present invention proposes a pickup assembly 36 for removing the protective sheet 101 on the pole core 102 . The pickup assembly 36 can better remove the protective sheet 101 from the pole core 102 without damaging the pole core 102 .

[0070] Reference below Figure 2-Figure 8 A pickup assembly 36 according to an embodiment of the present invention is described.

[0071] like Figure 2-Figure 8 As shown, according to an embodiment of the present invention, the picking assembly 36 is used to remove the protective sheet 101 on the pole core 102. The picking assembly 36 includes a first mounting bracket 361, a picking piece 362 and a pressing block 363. The picking piece 362 is provided with at least one, and the picking piece 362 is installed on the first mounting bracket 361. The pressing block 363 is installed on the first mounting bracket 361. Exemplarily, at least two pressing blocks 363 are provided, and the two pressing blocks 363 are respectively located on both sides of the picking piece 362, and are used to press the edges on opposite sides of the protective sheet 101, wherein the pressing block 363 is used to press and warp the protective sheet 101 to separate part of the protective sheet 101 from the pole core 102, so that the picking piece 362 can smoothly pick up the protective sheet 101.

[0072] That is to say, the two pressing blocks 363 can be respectively installed on the first mounting bracket 361, and when the picking member 362 picks up the protective sheet 101, the two pressing blocks 363 can be respectively pressed on the edges on both sides of the protective sheet 101, so that the protective sheet 101 is bent, that is, the two pressing blocks 363 make the protective sheet 101 constructed as an arc with an opening away from the picking member 362, so that the middle area of ​​the protective sheet 101 is separated from the pole core 102, thereby, the picking member 362 can better remove the protective sheet 101 from the pole core 102, the structure is simple, and the operation is convenient, which can reduce the risk of damaging the pole core 102 when removing the protective sheet 101 on the pole core 102.

[0073] Exemplarily, one pressing block 363 may also be provided, and one pressing block 363 causes one side of the protection sheet 101 to tilt up, thereby separating part of the protection sheet 101 from the pole core 102 .

[0074] Exemplarily, three or more pressing blocks 363 may be provided. When three or more pressing blocks 363 are provided, the arrangement of the positions of the pressing blocks 363 is based on the core principle of being able to press on the outer periphery on both sides of the protective sheet 101. The multiple pressing blocks 363 on each side may be arranged at intervals or not, and this application does not impose any restrictions.

[0075] According to the picking component 36 of the embodiment of the present invention, the pressing block 363 can be pre-pressed on the protective sheet 101, so that the protective sheet 101 can be partially separated from the pole core 102 before being picked up, so that the picking member 362 can reduce the difficulty of picking up the protective sheet 101. In addition, when the picking member 362 picks up the protective sheet 101, the damage to the pole core 102 can also be reduced. Moreover, the picking component 36 of the present application has a simple structure and is easy to operate.

[0076] In some embodiments of the present invention, a plurality of picking members 362 are provided, and the length of the picking members 362 gradually increases in the direction from the picking members 362 to the pressing block 363 .

[0077] like Figure 2 and Figure 8 In the example shown, the pressing block 363 is fixed on the first mounting bracket 361. In the direction from the first mounting bracket 361 to the protective sheet 101, the distance between the pressing block 363 and the protective sheet 101 is a first distance, and the distance between the picking member 362 and the protective sheet 101 is a second distance, and the first distance is smaller than the second distance. That is to say, the pressing block 363 is fixed after being installed on the first mounting bracket 361, and the external driving structure can drive the movement of the pressing block 363 by driving the movement of the first mounting bracket 361, that is, the first mounting bracket 361 can move toward the direction of the protective sheet 101, thereby driving the picking member 362 and the pressing block 363 to move toward the protective sheet 101 at the same time. Since the first distance is smaller than the second distance, the pressing block 363 will first contact the protective sheet 101. As the first mounting bracket 361 continues to move, the pressing block 363 pressed on the edges of both sides of the protective sheet 101 can cause the protective sheet 101 to bend, thereby separating the protective sheet 101 from the pole core 102. When the first mounting bracket 361 continues to move for a certain distance, the picking member 362 will contact the protective sheet 101 and pick up the protective sheet 101. According to the warping of the protection sheet 101 , the length of the picking member 362 near the pressing block 363 is longer than the length of the picking member 362 far from the pressing block 363 , so that the picking member 362 can better pick up the protection sheet 101 .

[0078] Exemplarily, the pressing block 363 can also be driven by a driving structure alone, that is, the driving structure can be installed on the first mounting bracket 361, and the pressing block 363 can be movably installed on the first mounting bracket 361, and then the driving structure can drive the pressing block 363 to move. This application does not impose any restrictions on this.

[0079] In some embodiments of the present invention, a plurality of picking members 362 are provided, and the distance between the picking member 362 and the pressing block 363 is inversely proportional to the length of the picking member 362. Figure 2 and Figure 8 As shown, a plurality of picking members 362 are provided, and in the direction from the central area to the edge area of ​​the protection sheet 101, the plurality of picking members 362 are configured to gradually decrease the distance between them and the protection sheet 101, so that when the protection sheet 101 is in a warped state, the plurality of picking members 362 are all in contact with the protection sheet 101.

[0080] That is to say, since the protective sheet 101 is warped, when multiple picking members 362 are provided, in order to better pick up the protective sheet 101, the multiple picking members 362 can be respectively provided at different positions. In this way, after the protective sheet 101 is warped, the multiple picking members 362 can better pick up the protective sheet 101.

[0081] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, the first mounting bracket 361 has a symmetry plane X, wherein the number of picking members 362 is an odd number, one of the plurality of picking members 362 is a first picking member, and the remaining picking members 362 are second picking members, the first picking member is located on the symmetry plane X, and the plurality of second picking members are symmetrically arranged along the symmetry plane X, or, the number of picking members is an even number, and the plurality of picking members are symmetrically arranged along the symmetry plane X.

[0082] For example, Figure 2 and Figure 8 As shown, the symmetric plane X of the first mounting bracket 361 is the symmetric plane X of the protective sheet 101, the protective sheet 101 in the warped state is symmetrical along the symmetric plane X, and the plurality of picking members 362 and the plurality of pressing blocks 363 are symmetrically arranged along the symmetric plane X. Thus, the plurality of pressing blocks 363 can make the warping of the protective sheet 101 more uniform, and the plurality of picking members 362 can also better pick up the protective sheet 101.

[0083] In some embodiments of the present invention, the picking member 362 includes a suction cup, whereby the suction cup can better absorb the protective sheet 101 through negative pressure after coming into contact with the protective sheet 101, and is not likely to cause damage to the protective sheet 101, thereby allowing the protective sheet 101 to be better reused.

[0084] Reference below Figure 1-Figure 6 A protection sheet removal mechanism 100 according to an embodiment of the present invention is described.

[0085] like Figure 1-Figure 6 As shown, according to the protective sheet removal mechanism 100 of an embodiment of the present invention, the protective sheet removal mechanism 100 is used to remove the protective sheet 101 on the pole core 102. The protective sheet removal mechanism 100 includes: a workbench 1 and a first picking structure 3. The workbench 1 is used to place the pole core 102 with the protective sheet 101. The first picking structure 3 is installed on the workbench 1. The first picking structure 3 is used to pick up the protective sheet 101 of the pole core 102.

[0086] Exemplarily, the workbench 1 is suitable for placing a plurality of pole cores 102 with protective sheets 101 . When there are a plurality of picking assemblies 36 , the plurality of picking assemblies 36 pick up the protective sheets 101 of the plurality of pole cores 102 in a one-to-one correspondence.

[0087] According to the protective sheet removal mechanism 100 of the embodiment of the present invention, by providing the pickup assembly 36 of the above embodiment, the protective sheet 101 on the pole core 102 can be removed well, the operation is simple and convenient, and it is not easy to cause damage to the pole core 102.

[0088] In some embodiments of the present invention, Figure 1 , Figure 2 , Fig.12 As shown, the first picking structure 3 also includes a first driving member 31, a picking assembly 36 and a movable member 35. The first driving member 31 is installed on the picking bracket 34. The movable member 35 is movably installed on the picking bracket 34 along a first direction. The first driving member 31 is used to drive the movable member 35 to move. At least one picking assembly 36 is installed on the movable member 35.

[0089] like Figure 2 , Fig.12 As shown, the first picking structure 3 also includes: a picking bracket 34 and a movable part 35, the movable part 35 is movably mounted on the picking bracket 34 along a first direction, the first driving part 31 is mounted on the picking bracket 34, and is used to drive the movable part 35 to move, and the first picking component 32 and the second picking component 33 are both mounted on the movable part 35.

[0090] That is to say, by installing both the first pickup component 32 and the second pickup component 33 on the movable part 35 and making the first driving part 31 drive the movable part 35 to move, the first pickup component 32 and the second pickup component 33 can be better controlled to move in the up and down directions at the same time, and the first pickup component 32 and the second pickup component 33 have good consistency when moving in the up and down directions. In addition, the driving method is simple, and only one driving part is required to simultaneously drive the first pickup component 32 and the second pickup component 33 to move in the up and down directions.

[0091] In some embodiments of the present invention, Fig. 9 , Fig.10 As shown, the first picking structure 3 also includes a pressing assembly 37, which includes: a pressing bracket 371, which is suitable for moving along the first direction, and is used to press on the outer periphery of the pole core 102 so that the picking assembly 36 can smoothly pick up the protective sheet 101.

[0092] In other words, the pressing bracket 371 can be driven to move through the driving structure. When the pressing bracket 371 is pressed on the outer periphery of the pole core 102 and the picking member 362 picks up the protective sheet 101, the position of the pole core 102 is relatively stable and is not easily moved by the movement of the protective sheet 101, thereby making it difficult for the pole core 102 to shift and be damaged.

[0093] In some embodiments of the present invention, Fig. 9 , Fig.10 As shown, the pressing bracket 371 is an annular frame surrounding the picking member 362 of the picking assembly 36, and the picking member 362 is suitable for passing through the middle channel 372 of the pressing bracket 371 to pick up the protection sheet 101. That is, after the pressing bracket 371 is pressed on the outer periphery of the pole core 102, the picking member 362 can pass through the middle channel 372 of the pressing bracket 371 to contact the protection sheet 101. When the picking member 362 picks up the protection sheet 101, both the picking member 362 and the protection sheet 101 can pass through the middle channel 372, thereby completing the removal of the protection sheet 101.

[0094] In some embodiments of the present invention, Fig. 9 , Fig.10 As shown, at least one buffer 373 is provided on the side of the pressing bracket 371 facing the workbench 1, and the buffer 373 can reduce the damage of the pressing bracket 371 to the pole core 102. Optionally, the buffer 373 includes a brush. Optionally, the buffer 373 can also be made of soft rubber material, which is not limited in this application.

[0095] Exemplarily, when the buffer member 373 is a brush, when the brush presses the pole core 102, it is not easy to attract the pole core 102, that is, when the brush is separated from the pole core 102, it is not easy to drive the pole core 102 to move, so that the pole core 102 is not easy to shift and thus not easy to be damaged.

[0096] In some embodiments of the present invention, Figure 1 , Figure 2 and Fig.11 As shown, the protective sheet removal mechanism 100 also includes a first flipping assembly 2, which is suitable for flipping the pole core 102 located at the first position and placing it at the second position, and the first picking structure 3 is suitable for picking up the protective sheet 101 of the pole core 102 at the first position and the protective sheet 101 of the pole core 102 at the second position.

[0097] For the convenience of description in the present invention, the protective sheets 101 on both sides of the pole core 102 are respectively referred to as the first protective sheet and the second protective sheet. The structure and size of the first protective sheet and the second protective sheet may be the same or different. The present invention does not make any limitation thereto. This is only for the convenience of describing the following schemes of the present invention.

[0098] The protective sheet 101 includes a first protective sheet and a second protective sheet located on both sides of the pole core 102. The protective sheet removal mechanism 100 includes: a workbench 1, a first flipping component 2 and a first picking structure 3. The pole core 102 is placed on the workbench 1. The workbench 1 has a first position and a second position. The first flipping component 2 is suitable for flipping the pole core 102 located at the first position and placing it at the second position. The first picking structure 3 includes a first driving member 31, a first picking component 32 and a second picking component 33. The first driving member 31 is used to drive the first picking component 32 and the second picking component 33 to move along a first direction, so that the first picking component 32 picks up the first protective sheet of the pole core 102 at the first position, and the second picking component 33 picks up the second protective sheet of the pole core 102 at the second position.

[0099] Exemplarily, the first direction can be an up-and-down direction, and the pole core 102 with the first protective sheet and the second protective sheet can be placed at the first position of the workbench 1, and the first protective sheet is located above the pole core 102. The first picking structure 3 can drive the first picking component 32 to move in the up-and-down direction through the first driving member 31 to pick up the first protective sheet on the pole core 102. Then, the first flipping component 2 can flip the pole core 102 with only the second protective sheet, and the flipping angle can be 180°, and the pole core 102 with only the second protective sheet is placed at the second position of the workbench 1. At this time, the second protective sheet is located on the upper side of the pole core 102. At this time, the first driving member 31 can drive the second picking component 33 to move in the up-and-down direction to pick up the second protective sheet on the pole core 102.

[0100] Furthermore, when the first flipping component 2 flips the pole core 102 with only the second protective sheet and places the pole core 102 with only the second protective sheet at the second position of the workbench 1, the pole core 102 with the first protective sheet and the second protective sheet can continue to be placed at the first position of the workbench 1, and the first protective sheet is located above the pole core 102. At this time, the first driving member 31 can simultaneously drive the first picking component 32 and the second picking component 33 to move in the up and down directions, thereby respectively picking up the first protective sheet for the pole core 102 at the first position and picking up the second protective sheet for the pole core 102 at the second position. Therefore, the protective sheet removal mechanism 100 of the present invention can remove the protective sheets 101 from two different pole cores 102 at the same time, thereby better improving the removal efficiency of the protective sheets 101.

[0101] Exemplarily, the workbench 1 can have multiple first positions and multiple second positions at the same time, and the number of the multiple first positions is equal to the number of the multiple second positions and corresponds one to one, that is, each pole core 102 placed at the first position can be placed at the corresponding second position after being flipped by the first flipping assembly 2. Therefore, by constructing multiple first positions and multiple second positions on the workbench 1, the protective sheet removal mechanism 100 of the present invention can remove the protective sheets 101 from multiple pole cores 102 at the same time, thereby further improving the removal efficiency of the protective sheet 101.

[0102] Therefore, the protective sheet removal mechanism 100 according to the embodiment of the present invention can better remove the protective sheet 101 from two or more pole cores 102 by providing the first flip assembly 2 and the first pick-up structure 3, and can better improve the removal efficiency of the protective sheet 101. In addition, the protective sheet removal mechanism 100 of the present invention has a simple structure, is easy to operate, and has a low manufacturing cost.

[0103] Exemplarily, the first picking component 32 or the second picking component 33 may include a suction cup or a mechanical claw, which is not limited in the present invention.

[0104] In some embodiments of the present invention, Figure 2 , Fig.10 As shown, the workbench 1 includes a first workbench 11 and a second workbench 12 which are spaced apart, the first position is located on the first workbench 11, and the second position is located on the second workbench 12. That is to say, when the first picking structure 3 picks up the first protection sheet and the second protection sheet, the pole core 102 with the first protection sheet and the pole core 102 with the second protection sheet are respectively arranged on the two spaced apart first workbench 11 and second workbench 12, so that the first protection sheet and the second protection sheet can be picked up at the same time, which can improve the overall efficiency, and during the picking up action, the first picking component 32 and the second picking component 33, as well as the first protection sheet and the second protection sheet are not likely to interfere with each other, and the first picking structure 3 can also have better accuracy when the first picking component 32 and the second picking component 33 are simultaneously picking up, and confusion is not likely to occur. Therefore, the protection sheet removal mechanism 100 of the present invention has high control accuracy and is not likely to be confused.

[0105] In some embodiments of the present invention, the first workbench 11 and the second workbench 12 are spaced apart along the second direction, the first flip assembly 2 is located between the first workbench 11 and the second workbench 12, and the first direction and the second direction are perpendicular to each other.

[0106] For example, the second direction can refer to the attached Figure 2In the left-right direction shown, the first workbench 11 and the second workbench 12 are spaced apart in the left-right direction, and the first flipping assembly 2 is located between the first workbench 11 and the second workbench 12, so that the first flipping assembly 2 can better pick up the pole core 102 with only the second protective sheet on the first workbench 11, and after the first flipping assembly 2 flips the pole core 102 with only the second protective sheet, it can also better place the pole core 102 on the second workbench 12.

[0107] Exemplarily, the first workbench 11 and the second workbench 12 are symmetrically arranged along the rotation axis of the first flipping assembly 2. In this way, after the first flipping assembly 2 flips the pole core 102 having only the second protective sheet, the pole core 102 can be directly placed on the second workbench 12, which can improve the working efficiency of the first flipping assembly 2.

[0108] In some embodiments of the present invention, Figure 2 As shown, the first flipping assembly 2 includes: a flipping bracket 21, a clamping member 22, a second driving member 23 and a third driving member 24. The clamping member 22 is rotatably mounted on the flipping bracket 21 around a first rotation axis. The second driving member 23 is used to drive the clamping member 22 to rotate around the first rotation axis. The third driving member 24 is used to drive the clamping member 22 to clamp the pole core 102 or release the clamping action of the pole core 102.

[0109] That is to say, when the pole core 102 in the first position needs to be flipped, the third driving member 24 can drive the clamping member 22 to clamp the pole core 102, and then the second driving member 23 can drive the clamping member 22 to rotate 180°, so that the second protective sheet is above the pole core 102. At this time, the pole core 102 can be located in the second position, and the third driving member 24 drives the clamping member 22 to release the pole core 102, thereby completing the flipping of the pole core 102 and completing the transportation of the pole core 102 from the first position to the second position. The structure is simple and the operation is convenient.

[0110] Exemplarily, the clamping member 22 may include a first clamping jaw and a second clamping jaw, and the third driving member 24 may drive the first clamping jaw and the second clamping jaw to move closer to or away from each other, thereby achieving the clamping work of the clamping member 22 on the protective member.

[0111] In some embodiments of the present invention, the protective sheet removal mechanism 100 further includes a driving assembly 30, and the first picking structure 3 is mounted on the driving assembly 30, and the driving assembly 30 is used to drive the first picking structure 3 to move along a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0112] Exemplarily, the first direction is the up and down direction, and the second direction is the left and right direction. After the first picking structure 3 picks up the protective sheet 101, the driving component 30 can drive the first picking structure 3 to move along the left and right direction. When the first picking structure 3 is moved to the next workstation, the first picking structure 3 can place the protective sheet 101 at the next workstation.

[0113] Exemplarily, the driving component 30 can drive the first picking structure 3 to move in the left-right direction to above the protective sheet conveying mechanism 200, and then the first picking structure 3 can drive the first picking component 32 and the second picking component 33 in the up-down direction, so that the first protective sheet picked up by the first picking component 32 and the second protective sheet picked up by the second picking component 33 are placed on the conveying component 4 of the protective sheet conveying mechanism 200.

[0114] In the related art, after the protective sheet 101 is removed from the pole core 102, the protective sheet 101 is often placed in a material box. The protective sheets 101 are also prone to friction with each other during the collection process of the material box, which may cause foreign matter to be generated on the protective sheet 101, thereby increasing the quality risk when the protective sheet 101 is reused.

[0115] Based on this, the present invention also proposes a protective sheet conveying mechanism 200, after the protective sheet removing mechanism 100 removes the protective sheet 101 from the pole core 102, the protective sheet 101 can be placed on the protective sheet conveying mechanism 200, thus eliminating the use of a material box, so that the protective sheet 101 can be directly transported to the next station for use, avoiding damage caused by mutual friction of the protective sheet 101 in the material box, and reducing foreign matter on the protective sheet 101. Thus, when the protective sheet 101 is reused, the quality risk is reduced.

[0116] like Figure 1 and Figure 7 As shown, the protective sheet conveying mechanism 200 according to an embodiment of the present invention can be used to convey the protective sheet 101, and the protective sheet conveying mechanism 200 includes: a conveying component 4 and a second picking structure 5, the conveying component 4 is suitable for conveying the protective sheet 101, the second picking structure 5 is suitable for picking up the protective sheet 101 on the conveying component 4, and is suitable for transporting the protective sheet 101 along the conveying direction; wherein, the protective sheet conveying mechanism 200 also includes: a cleaning component 6, a detection component 7, a waste discharge bin 8 and a replenishing bin 9 which are arranged in sequence along the conveying direction, the cleaning component 6 is suitable for cleaning the protective sheet 101 on the second picking structure 5, the detection component 7 is suitable for detecting the protective sheet 101 on the second picking structure 5, the second picking structure 5 is suitable for placing the defective protective sheet 101 on the second picking structure 5 in the waste discharge bin 8, the replenishing bin 9 stores the good protective sheet 101, and the second picking structure 5 which places the defective protective sheet 101 in the waste discharge bin 8 is suitable for picking up the good protective sheet 101 in the replenishing bin 9.

[0117] For example, Figure 7 As shown, after the protective sheet removal mechanism 100 places the protective sheet 101 on the conveying component 4, the conveying component 4 can convey the protective sheet 101 in the front-to-back direction. After the protective sheet 101 is conveyed to the next workstation, the second picking structure 5 can pick up the protective sheet 101 on the conveying component 4, and the second picking structure 5 can continue to transport the protective sheet 101 in the front-to-back direction after picking up the protective sheet 101, and in the conveying direction of the second picking structure 5, the protective sheet 101 can be cleaned by the cleaning component 6 in turn to remove foreign matter on the surface of the protective sheet 101, and the detection component 7 can detect the cleaned protective sheet 101 to determine whether there are still foreign matter remaining on the protective sheet 101, or whether the protective sheet 101 is a defective product that has been deformed or even broken.

[0118] Furthermore, if the protection sheet 101 is a good product, the second picking structure 5 can continue to move along the conveying direction to place the good protection sheet 101 on the conveying component 4 .

[0119] If the protection sheet 101 is a defective product, the second picking structure 5 can place the protection sheet 101 in the waste discharge bin 8 when transporting the protection sheet 101 to the top of the waste discharge bin 8. At this time, the second picking structure 5 can continue to move along the conveying direction to the top of the replenishment bin 9, and then pick up the good protection sheet 101 from the replenishment bin 9. Then, the second picking structure 5 can continue to move along the conveying direction and place the good protection sheet 101 on the conveying component 4. The conveying component 4 can then convey the good protection sheet 101 to the next operating station, so that the protection sheet 101 can be used directly. Moreover, even if the protection sheet 101 is defective, it can be directly replenished with good protection sheets 101, which will not affect the use of the protection sheet 101 at the next operating station.

[0120] Therefore, according to the protective sheet conveying mechanism 200 of the embodiment of the present invention, by placing the protective sheet 101 on the conveying component 4, the use of the material box can be eliminated, so that the protective sheet 101 can be directly transported to the next station for use, which can avoid damage caused by mutual friction between the protective sheets 101 in the material box, and reduce foreign matter on the protective sheet 101. Thereby, when the protective sheet 101 is reused, the quality risk is reduced. In addition, the protective sheet conveying mechanism 200 of the present invention can detect the protective sheet 101. Even if the protective sheet 101 is defective, it can be directly supplemented with a good protective sheet 101, which does not affect the use demand of the protective sheet 101 of the next operating station.

[0121] In some embodiments of the present invention, the second picking-up structure 5 includes a plurality of picking-up portions, each of which is suitable for picking up a protective sheet 101. Figure 7As shown, the second picking structure 5 includes a third picking component 51 and a fourth picking component 52. The second picking structure 5 also includes a second mounting bracket 53 and a movable bracket 54. The movable bracket 54 can be movably mounted on the second mounting bracket 53 along the conveying direction of the conveying component 4. The third picking component 51 and the fourth picking component 52 are mounted on the movable bracket 54. The third picking component 51 and the fourth picking component 52 are respectively suitable for picking up a protective sheet 101.

[0122] Exemplarily, the protective sheet 101 picked up by the third picking component 51 is the first protective sheet, and the protective sheet 101 picked up by the fourth picking component 52 is the second protective sheet. The first protective sheet and the second protective sheet are a pair placed on both sides of the pole core 102. In this way, when the second picking structure 5 picks up the protective sheet 101 on the conveying component 4, the first protective sheet and the second protective sheet can be picked up at the same time by the third picking component 51 and the fourth picking component 52. Then, the first protective sheet and the second protective sheet are cleaned by the cleaning component 6 and inspected by the inspection component 7, and the first protective sheet or the second protective sheet of the defective product is replaced. Then, they can be directly placed in the conveying component 4 and conveyed to the next workstation. The next workstation can directly obtain two protective sheets 101. When the two protective sheets 101 are placed on both sides of the pole core 102, since the next workstation obtains two protective sheets 101 each time, it can play a certain anti-fool effect and can better reduce the risk of misplacing or missing the protective sheet 101.

[0123] In some embodiments of the present invention, Figure 7 As shown, the protection sheet conveying mechanism 200 further includes: a second flipping assembly 10 , which is suitable for receiving the protection sheet 101 on the second picking structure 5 and flipping the protection sheet 101 to place the flipped protection sheet 101 on the conveying assembly 4 .

[0124] Exemplarily, the second picking structure 5 is located above the conveying component 4, and the second picking structure 5 can control the third picking component 51 and the fourth picking component 52 to move in the up and down directions, while the cleaning component 6 and the detection component 7 both clean and detect the lower side of the first protective sheet and the second protective sheet. Here, for the sake of convenience, the surface of the protective sheet 101 after cleaning and detection is called the working surface, that is, the surface facing the pole core 102. In order to prevent the second picking structure 5 from turning the working surface of the good protective sheet 101 toward the conveying component 4, the protective sheet 101 can be flipped 180° by the second flipping component 10, so that after the protective sheet 101 is placed on the conveying component 4, the working surface of the protective sheet 101 faces upward, thereby effectively reducing the risk of the working surface being affected by foreign objects on the conveying component 4.

[0125] In some embodiments of the present invention, Figure 7As shown, the conveying component 4 includes a first conveying component 41 and a second conveying component 42. In the direction from the first conveying component 41 to the second conveying component 42, the cleaning component 6, the detection component 7, the waste discharge bin 8 and the replenishing bin 9 are arranged in sequence. The first conveying component 41 and the second conveying component 42 both extend along the third direction and are spaced apart along the third direction.

[0126] Exemplarily, the third direction is the front-to-back direction, and the first conveying component 41, the cleaning component 6, the detection component 7, the waste discharge bin 8, the replenishing bin 9 and the second conveying component 42 are arranged in sequence, that is, the first conveying component 41, the cleaning component 6, the detection component 7, the waste discharge bin 8, the replenishing bin 9 and the second conveying component 42 are all located on the same straight line. Therefore, the reasonable arrangement of the positions of each component can improve the efficiency of the entire production line, and the position and configuration can be flexibly adjusted as needed to facilitate maintenance and upgrading.

[0127] Exemplarily, the conveying assembly 4 may be a belt conveying assembly 4 . The belt conveying assembly 4 can not only transport the protection sheet 101 well, but also is not easy to damage the protection sheet 101 due to the flexibility of the belt.

[0128] Exemplarily, the cleaning component 6 may be a brush or a hair dryer, etc., but the present invention is not limited thereto.

[0129] Exemplarily, the detection component 7 may be an infrared detection component 7 or a camera, etc., and the present invention does not limit this.

[0130] Exemplarily, the third pickup component 51 or the fourth pickup component 52 may be a suction cup or a mechanical clamp, which is not limited in the present invention.

[0131] The present invention further proposes a protection sheet removal and conveying system 1000 having the protection sheet removal mechanism 100 of the above embodiment and the protection sheet conveying mechanism 200 of the above embodiment.

[0132] like Figure 1-Figure 7 As shown, the protection sheet removal and conveying system 1000 according to the embodiment of the present invention includes a protection sheet removal mechanism 100 and a protection sheet conveying mechanism 200 , and the first picking structure 3 is used to place the picked-up protection sheet 101 on the conveying component 4 .

[0133] According to the protective sheet removal and conveying system 1000 of the embodiment of the present invention, by providing the protective sheet removal mechanism 100 of the above embodiment and the protective sheet conveying mechanism 200 of the above embodiment, the protective sheet 101 can be better removed from the pole core 102, and the removed protective sheet 101 can also be better conveyed to the predetermined work station, thereby eliminating the use of material boxes and improving the overall production efficiency.

[0134] Other structures and operations of the protection sheet removal mechanism 100 , the protection sheet conveying mechanism 200 and the protection sheet removal and conveying system 1000 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail herein.
