DETAILED DESCRIPTION

[0035] The application will be further described below in conjunction with the drawings and examples.

[0036] As Figures 1-8 shown: a diaphragm roll changing and carrying equipment for lithium battery diaphragm production line, the equipment includes translation chassis 1, driving side rotating arm 2, driven side rotating arm 3, transmission synchronization rod 4, driven synchronization rod 5, winding core bracket jig 6 and cantilever driving mechanism 8, wherein the driving side rotating arm 2 and the driven side rotating arm 3 are respectively arranged on the translation chassis 1 and can rotate relative to the translation chassis 1 under the action of the cantilever driving mechanism 8, at least one transmission synchronization rod 4 is connected between the driving side rotating arm 2 and the driven side rotating arm 3, and two driven synchronization rods 5 respectively fixedly provided with winding core bracket jigs 6 are connected, the cantilever driving mechanism 8 drives the driving side rotating arm 2 and the driven side rotating arm 3 to rotate in the same direction through the transmission synchronization rod 4, and the two driven synchronization rods 5 are reversely rotated synchronously, so that the winding core bracket jig 6 on the driven synchronization rod 5 always maintains a vertical upward state. The cantilever driving mechanism 8 inputs power from the driving side rotating arm 2, synchronously rotates the driven side rotating arm 3 through the transmission synchronization rod, exchanges the full winding winding core mother roll 61 and the empty winding winding core mother roll 61 on the winding core bracket jig 6 with each other, and simultaneously moves on the ground rail 7 through the translation chassis 1, so as to place the full winding winding core mother roll 61 and the empty winding winding core mother roll 61 on the corresponding equipment respectively, thereby realizing the functions of automatic roll changing and winding core carrying.

[0037] Due to the large weight of the take-up core roll 61, in order to ensure the space requirements for changing between a fully wound take-up core roll 61 and an empty take-up core roll 61, the active-side rotating arm 2 is driven by a drive motor 80 through a reducer 81 and various gear meshing for multi-stage reduction to ensure the torque requirements necessary for heavy-load operation. In this invention, the cantilever drive mechanism 8 uses multi-stage reduction transmission to drive the active-side planetary gear set inside the active-side rotating arm 2.

[0038] The following is an example of a three-stage reduction transmission: The cantilever drive mechanism 8 includes a drive motor 80, a reducer 81, a first transmission gear 83, a fourth transmission gear 86, a fifth transmission gear 87, and a sixth transmission gear 88. The reducer 81 is mounted on the active side bracket 11 via a reducer base 82. The reducer 81 is driven by the drive motor 80. The output shaft of the reducer 81 is equipped with a first transmission gear 83, which meshes with the fourth transmission gear 86. The fourth transmission gear 86 and the fifth transmission gear 87, which are coaxially arranged, rotate synchronously and are mounted on the active side fixed center shaft 20. The fifth transmission gear 87 meshes with the sixth transmission gear 88, which is located at the end of the transmission synchronizing rod 4. In the above structure, the reducer 81 is a first-stage reduction, the meshing transmission of the first transmission gear 83 and the fourth transmission gear 86 constitutes a second-stage reduction, and the meshing transmission of the fifth transmission gear 87 and the sixth transmission gear 88 constitutes a third-stage reduction.

[0039] like Figures 2-4 As shown, the following is an example of a four-stage reduction transmission: The cantilever drive mechanism 8 includes a drive motor 80, a reducer 81, a first transmission gear 83, a second transmission gear 84, a third transmission gear 85, a fourth transmission gear 86, a fifth transmission gear 87, and a sixth transmission gear 88. The reducer 81 is mounted on the active side bracket 11 via a reducer base 82. The reducer 81 is driven by the drive motor 80. A first transmission gear 83 is mounted on the output shaft of the reducer 81. The first transmission gear 83 meshes with the second transmission gear 84. The second transmission gear 84 and the third transmission gear 85, which are coaxially arranged, rotate synchronously. The third transmission gear 88... 5 meshes with transmission gear 4 86, and transmission gear 5 87, which are coaxially arranged, rotate synchronously and are mounted on the fixed central shaft 20 on the active side. Transmission gear 5 87 meshes with transmission gear 6 88, which is located at the end of transmission synchronizing rod 4. In the above structure, reducer 81 is a first-stage reducer, transmission gear 1 83 and transmission gear 2 84 mesh to form a second-stage reducer, transmission gear 3 85 and transmission gear 4 86 mesh to form a third-stage reducer, and transmission gear 5 87 and transmission gear 6 88 mesh to form a fourth-stage reducer.

[0040] In the multi-stage reduction mechanism of the cantilever driving mechanism 8, the number of teeth of the driving gear as the driving gear in each driving gear set is smaller than the number of teeth of the driving gear as the driven gear in each driving gear set, and the number of teeth of the driving gear as the driven gear in each driving gear set increases with the increase of the number of reduction stages. Like the present application Figures 2-4 In the four-stage reduction mechanism, the driving gear one 83 as the driving gear in the second-stage reduction mechanism is a 28-tooth involute straight gear, the number of teeth of the driving gear two 84 as the driven gear in the second-stage reduction mechanism, the number of teeth of the driving gear four 86 as the driven gear in the third-stage reduction mechanism, and the number of teeth of the driving gear six 88 as the driven gear in the fourth-stage reduction mechanism are all more than twice the number of teeth of the driving gear one 83 as the driving gear, and the number of teeth of the driving gear two 84 is smaller than the number of teeth of the driving gear four 86, and the number of teeth of the driving gear four 86 is smaller than the number of teeth of the driving gear six 88.

[0041] As shown in Figures 2-4 The driving side fixed central shaft 20 is provided with a rotating shaft sleeve 89, the driving gear four 86 and the driving gear five 87 are fixedly arranged at both ends of the rotating shaft sleeve 89, and the rotating arm central shaft sleeve 810 is sleeved on the rotating shaft sleeve 89 between the driving gear four 86 and the driving gear five 87. The end wall of the rotating arm central shaft sleeve 810 adjacent to the driving gear five 87 is fixedly provided with the outer wall of the box of the driving side rotating arm 2, so that the driving gear five 87 and the driving gear six 88 are located in the box of the driving side rotating arm 2. The driving side fixed central shaft 20 inside the driving gear five 87 is further provided with the driving side driving gear 21 in the driving side spur gear set, and the driving side driving gear 21 is further provided with the driving side driving gear A 22 in the driving side spur gear set on the driving synchronous rod 4 inside the driving gear six 88. The driving side driving gear A 22 is connected in meshing engagement with the driving side driving gear 21.

[0042] As shown in Figures 2-4As shown, the active side planetary gear set includes the same modulus and the same number of teeth of the active side toothed gear 21, the active side driving wheel A 22, the active side driven wheel B 23, the active side driving wheel C 24, and the active side driven wheel D 25. The active side toothed gear 21 is fixed on the active side fixed center shaft 20 and remains stationary. The active side driving wheel A 22, the active side driven wheel B 23, the active side driving wheel C 24, and the active side driven wheel D 25 rotate around the active side toothed gear 21 and can rotate by themselves. The rotation direction of the active side driving wheel A 22 and the active side driving wheel C 24 is opposite to that of the active side driven wheel B 23 and the active side driven wheel D 25. The active side driving wheel A 22 on the transmission synchronizing rod 4 rotates under the drive of the cantilever driving mechanism 8, drives the active side driven wheel B 23 engaged with it to rotate reversely and synchronously, and rotates around the active side toothed gear 21 to drive the active side rotating arm 2 to rotate. The active side rotating arm 2 drives the active side driven wheel B 23, the active side driving wheel C 24, and the active side driven wheel D 25 to rotate synchronously around the active side toothed gear 21. The active side driving wheel C 24 rotating around the active side toothed gear 21 keeps rotating by itself under the meshing action of the active side driving wheel C 24 and the active side toothed gear 21. The rotation of the active side driving wheel C 24 drives the active side driven wheel D 25 engaged with it to rotate reversely and synchronously. The active side driven wheel B 23 and the active side driven wheel D 25 keep rotating synchronously in the same direction.

[0043] As shown, Figures 5-6 The driven side planetary gear set includes the same modulus and the same number of teeth of the driven side toothed gear 31, the driven side driving wheel A 32, the driven side driven wheel B 33, the driven side driving wheel C 34, and the driven side driven wheel D 35. The driven side toothed gear 31 is fixed on the driven side fixed center shaft 30 and remains stationary. The driven side driving wheel A 32, the driven side driven wheel B 33, the driven side driving wheel C 34, and the driven side driven wheel D 35 rotate around the driven side toothed gear 31 and can rotate by themselves. The rotation direction of the driven side driving wheel A 32 and the driven side driving wheel C 34 is opposite to that of the driven side driven wheel B 33 and the driven side driven wheel D 35. The driven side driving wheel A 32 rotates under the transmission action of the transmission synchronizing rod 4, drives the driven side driven wheel B 33 engaged with it to rotate reversely and synchronously, and rotates around the driven side toothed gear 31 to drive the driven side rotating arm 3 to rotate. The driven side rotating arm 3 drives the driven side driven wheel B 33, the driven side driving wheel C 34, and the driven side driven wheel D 35 to rotate synchronously and around the driven side toothed gear 31. The driven side driving wheel C 34 rotating around the driven side toothed gear 31 keeps rotating by itself under the meshing action of the driven side driving wheel C 34 and the driven side toothed gear 31. The rotation of the driven side driving wheel C 34 drives the driven side driven wheel D 35 engaged with it to rotate reversely and synchronously. The driven side driven wheel B 33 and the driven side driven wheel D 35 keep rotating synchronously in the same direction.

[0044] In the design provided by the present application, the driving side transmission wheel C24 is supported in the box of the driving side rotating arm 2 by a driving side gear shaft 26, and the driven side transmission wheel C34 is supported in the box of the driven side rotating arm 3 by a driven side gear shaft 36; in the production practice, a synchronous rod can also be used as needed, for example, the driving side transmission wheel C24 and the driven side transmission wheel C34 are connected by the same transmission synchronous rod 4, and the transmission synchronous rod 4 can support the driving side transmission wheel C24 and the driven side transmission wheel C34 in the corresponding driving side rotating arm 2 box and the driven side rotating arm 3 box, respectively.

[0045] As shown in Figures 1-7 , the transmission synchronous rod 4 and the driven synchronous rod 5 of the present application both adopt the synchronous rod structure of the shaft coupling structure, which can adjust the width between the driving side rotating arm 2 and the driven side rotating arm 3 according to the length of the winding core mother roll 61. As shown in Figure 1 , Figure 7 , the winding core bracket jig 6 adopts a bearing type structure, and the empty or full winding core mother roll 61 is horizontally placed on the winding core bracket jig 6, and the upper surface of the winding core bracket jig 6 is embedded with anti-slip engineering plastic 60 to ensure that the winding core mother roll 61 will not move axially.

[0046] As shown in Figure 1 , the translation chassis 1 is driven to travel on the ground rail 7 by a chassis driving mechanism, and the driving side support 11 and the driven side support 12 are respectively arranged at both ends of the translation chassis 1, the driving side support 11 is used to install and support the cantilever driving mechanism 8 and the driving side rotating arm 2, and the driven side support 12 is used to install and support the driven side rotating arm 3. As shown in Figure 8 , the ground rail 7 is a common groove-shaped anti-overturning rail, and the rolling wheels of the translation chassis 1 are clamped in the groove-shaped area of the ground rail 7, and the anti-overturning design ensures the stability during the equipment carrying process; the chassis driving mechanism of the translation chassis 1 can drive a pair of gear and rack by a servo motor, that is, the servo motor drives the translation chassis 1 to move on the ground rail 7 through the transmission of the gear and rack; in addition, a protective sleeve is arranged on the ground rail 7.

[0047] In the present application, the space positions of the full winding core mother roll 61 and the empty winding core mother roll 61 are exchanged by the roll changing mechanism and the translation mechanism, the full winding core mother roll 61 and the empty winding core mother roll 61 are always balanced during the roll changing process by the planetary gear, and the gears used are all involute spur gears; the translation mechanism uses a gear and rack to drive the translation by a servo motor.

[0048] In order to explain the space roll changing principle of the present application, the space roll changing principle of the present application is provided Figure 9 andFigure 10 Explain. To ensure that the empty and full roll always maintain not falling and not overturning when space exchange, the roll changing mechanism adopts the following planetary gear set principle: the gears B, A, O, C, D arranged in the rotating arm box are sequentially meshed, when the driving gear A rotates clockwise by a certain angle, the whole rotating arm will rotate clockwise by the same angle, and then drive gear C to rotate clockwise by the same angle, while gear B and gear D will rotate counterclockwise by the same angle; similarly, when the driving gear A rotates counterclockwise by a certain angle, the whole rotating arm will rotate counterclockwise by the same angle, and then drive gear C to rotate counterclockwise by the same angle, while gear B and gear D will rotate clockwise by the same angle. If the roll core bracket jig 6 is horizontally fixed on the synchronous rod corresponding to the rotation center axis of gear B and gear D and the installation direction is vertically upward, then no matter how much the rotating arm rotates, the roll core bracket jig 6 can always keep vertical upward.
