Description

Technical Field

[0002] Roll-slitting is an essential step in lithium battery production. While this process is largely automated in traditional production, the resulting rolls need to be unloaded from the reel and then transported. This process often requires two to three people, including manual unloading and reel changing.

[0003] During the actual production process, it takes about 5 minutes for the slitting machine's winding mechanism to complete the unloading of one roll. Assuming that 4 rolls are wound, the unloading takes about 20 minutes. Adding the time for changing the rolls, it takes about 30 minutes to unload the slitting machine once. The time cost is high and the production efficiency is low, which greatly reduces the advantages brought by the technological improvement of the previous process. Summary of the Invention

[0070] The present invention discloses a loading device, a loading and unloading self-processing device provided with the loading device, and a slitting and unloading system provided with the loading and unloading self-processing device, which can replace the manual handling of empty barrels and further replace the manual handling of material rolls, which is beneficial to improving the degree of automation of the unloading process of the slitting machine, reducing labor costs and improving production efficiency.

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0072] First specific embodiment

[0073] See also Figure 1 and Figure 5 The first embodiment of the present invention provides a loading device, which includes a station conversion unit 101 and a winding unit 103.

[0074] The upper winding section 103 includes an upper winding core shaft 134, one end of which is connected to the station conversion section 101, and the other end of which can receive the empty barrel 143 by inserting and can be coaxially docked with the winding shaft 31 to push the empty barrel 143 onto the winding shaft 31;

[0075] The station conversion unit 101 can control the upper winding core shaft 134 to move to the upper winding position D, and can also control the upper winding core shaft 134 to move to the docking position A. When the upper winding core shaft 134 is at the upper winding position D, it can receive the empty barrel 143; when the upper winding core shaft 134 is at the docking position A, it can dock coaxially with the reel 31.

[0076] This loading device is suitable for the unloading process of a slitting machine. It can automatically install an empty barrel 32 onto the slitting machine's slip shaft 31, and then continue to wind the electrode sheets after roller slitting to form a roll 32. However, this is not limited to this application and can also be applied to other fields to achieve automatic roll loading. For ease of explanation, this article uses the auxiliary unloading of a lithium battery slitting machine as an example for specific description.

[0077] In this loading device, the station switching unit 101 can control the winding core shaft 134 to automatically switch between the docking position A and the winding position D, replacing the manual handling of the empty barrel 32. This helps to improve the automation level of the slitting machine unloading process, reduce labor costs, and improve production efficiency.

[0078] In a specific implementation, the upper roll portion 103 is further provided with a first connecting beam 133 and a first driving mechanism.

[0079] The first connecting beam 133 has two or more winding core shafts 134 arranged in sequence along its axial direction, forming an automatic coil feeding fork;

[0080] The first driving mechanism can control the first connecting beam 133 to rotate the upper winding core shaft 134 from the upper winding state to the lower winding state, and can control the first connecting beam 133 to rotate the upper winding core shaft 134 from the lower winding state to the upper winding state; when the upper winding core shaft 134 is in the upper winding state, it can receive the empty barrel 143; when the upper winding core shaft 134 is in the lower winding state, it can be coaxially docked with the winding shaft 31.

[0081] Specifically, see Figure 1 : When the upper winding part 103 is in the upper winding state, the multiple upper winding core shafts 134 are all located at the upper winding position D, and are basically at the same height, that is, they are arranged in parallel in the same horizontal plane, so as to facilitate the reception of the empty barrel 143; when the upper winding part 103 is in the lower winding state, the multiple upper winding core shafts 134 are all located at the docking position A, corresponding one by one to the multiple winding shafts 31 on the slitting machine, and are coaxially docked with them respectively, so that the empty barrel 143 can be moved to the winding shaft 31 respectively. At this time, the multiple upper winding core shafts 134 are generally arranged in parallel in the same vertical plane.

[0082] In specific implementation, the first driving mechanism generally includes a reducer (such as a rotary motor, a cylinder driven rotary structure), and a transmission mechanism thereof. For example, see Figure 1 The first driving mechanism includes a first motor 131 and a first driving shaft 132. The first driving shaft 132 is rotatably mounted on the turntable 113 of the station conversion part 101 through a tapered roller bearing and a support, and is transmission-connected to the first motor 131.

[0083] Furthermore, the upper winding section 103 is further provided with a clamping jaw 135 and a first control mechanism. The clamping jaw 135 can clamp the empty barrel 143 to position the empty barrel 143 on the upper winding core shaft 134 to prevent the empty barrel 143 from accidentally falling off or shaking. The first control mechanism can control the opening and closing of the clamping jaw 135.

[0084] Furthermore, the upper winding portion 103 is further provided with a second control mechanism, which can control the axial movement of the clamping jaws 135 along the upper winding core shaft 134. Thus:

[0085] When the upper winding section 103 receives an empty barrel 143 at the upper winding position D, the second control mechanism controls the clamping jaws 135 to move to the outer end of the upper winding core shaft 134 away from the station conversion section 101, where they clamp the empty barrel 143. The empty barrel 143 is then moved axially along the upper winding core shaft 134, allowing the empty barrels 143 to be fitted one by one onto the appropriate position on the upper winding core shaft 134. Furthermore, the first and second control mechanisms can be used to adjust the specific position of the empty barrel 143 on the upper winding core shaft 134.

[0086] When the upper winding part 103 rotates to the docking position A, the second control mechanism can clamp the empty barrels 143 one by one and push them to the outer end of the upper winding core shaft 134, and transfer them to the specified position on the winding shaft 31 (i.e., the slip shaft) in the slitting machine equipment, and then the clamping jaws 135 are released and retracted.

[0087] For specific implementation, see Figure 1 The clamping jaws 135 are a clamping mechanism similar to a scissors structure, which can clamp the empty barrel 143 and stably mount it on the upper winding core shaft 134. The first control mechanism can be a cylinder or a motor or other driving device that can control the degree of opening of the clamping jaws.

[0088] Furthermore, the second control mechanism includes a screw 139, a carriage 137, and a second drive mechanism 136. Screw 139 is rotatably mounted on first connecting beam 133, parallel to upper winding core shaft 134. Second drive mechanism 136 is used to drive screw 139 to rotate about its own axis. Slide 137 is used to mount jaws 135 and is provided with a threaded hole that mates with screw 138.

[0089] Specifically, the carriage 137 is provided with a first limiting hole that can be fitted over the upper winding core shaft 134, and the diameter of the first limiting hole is larger than that of the upper winding core shaft 134. Furthermore, a guide rod 138 is provided on the first connecting beam 133, and the carriage 137 is provided with a second limiting hole that can be fitted over the guide rod 138, and the diameter of the second limiting hole is larger than that of the guide rod 138. Thus, when the second driving mechanism 136 drives the screw rod 139 to rotate, the carriage 137 moves the clamping jaws 135 axially, thereby controlling the clamping jaws 135 to move to a specific position and then clamp the empty barrel 32 at that position, or controlling the clamping jaws 135 to move axially with the clamped empty barrel 32 to a specific position on the upper winding core shaft 134.

[0090] Specifically, see Figure 1The second drive mechanism 136 includes a drive motor, a drive wheel mounted on the output shaft of the drive motor, a driven wheel coaxially mounted on one end of a lead screw 139, and a transmission belt sleeved over the drive wheel and the driven wheel. However, this is not limiting. In other embodiments, the movement of the clamping jaw 135 can be controlled by other drive mechanisms, such as a linear cylinder, a linear motor, or a linear guide.

[0091] In order to further optimize the above technical solution, Figure 1 and Figure 5 As shown in FIG, the loading device further includes a roll feeding device 104, i.e., a roll core feeding device. The roll feeding device 104 includes a housing 141 and a roll feeding mechanism. The housing 141 can accommodate empty rolls 143 (including empty rolls 143 recovered by the AGV). The roll feeding mechanism can push the empty rolls 143 located at a target position in the housing 141 onto the upper roll core shaft 134.

[0092] Specifically, the roll-feeding mechanism includes a push cylinder 142 and a push mechanism that controls the axial movement of the push cylinder 142. On either side of the target location, the housing 141 has an inlet for the push cylinder 142 and an outlet for the empty roll 143. The push cylinder 142, the inlet, and the outlet are coaxially arranged. Thus, when the push mechanism controls the push cylinder 142 to extend into the housing inlet, it pushes the empty roll 143 at that location onto the winding core shaft 134.

[0093] In specific implementation, the pushing mechanism is a long-stroke servo push rod mechanism, which generally includes a push rod and a servo motor for controlling the movement stroke of the push rod. It can cooperate with the rotating mechanism of the work station conversion part 101 and the upper winding core shaft 134 to push the empty barrel 143 one by one to move to the upper winding core shaft 134 and maintain a fixed spacing.

[0094] Alternatively, in other specific embodiments, the pushing mechanism may employ a push rod and a cylinder for controlling the push rod's travel. Alternatively, the pushing mechanism may employ a gear transmission mechanism for driving the axial movement of the push cylinder 142, wherein the outer side of the push cylinder 142 is provided with a rack structure that meshes with the gear. In specific implementations, the pushing mechanism may be a drive mechanism capable of automatically controlling the travel, or a drive mechanism capable of manually controlling the travel. Those skilled in the art may design the mechanism based on actual needs.

[0095] Preferably, if Figure 2 As shown in FIG, a ramp structure 1411 is provided within the housing 141 to automatically move the empty barrel 143 to the target position (i.e., between the aforementioned inlet and outlet). Thus, when the empty barrel 143 at the target position within the housing 141 is pushed out by the pushing mechanism and the pushing mechanism returns to its position outside the housing, another empty barrel 143 automatically moves to the target position under the action of gravity, waiting to be pushed for reeling.

[0096] Alternatively, in other specific embodiments, an elastic mechanism (or a clip mechanism) may be provided within the housing 141 to automatically push the empty cartridge 143 to the target position. When the empty cartridge 143 at the target position within the housing 141 is pushed out by the pushing mechanism and returned to its position outside the housing, another new empty cartridge 143 is automatically pushed to the target position by the elastic mechanism to be rolled up.

[0097] It can be seen that the collection of the empty barrels 143 can be achieved through the coil supply device 104, and the empty barrels 143 can also be automatically filled. When the loading and unloading self-processing device is on standby, the empty barrels 143 can be automatically loaded onto the upper coil core shaft 134.

[0098] In specific implementation, the station conversion unit 101 in the loading device includes a linear drive mechanism and a rotation mechanism. Figure 1 :

[0099] The linear drive mechanism can control the material receiving portion 102 or the upper winding portion 103 to move linearly from the intermediate position C to the material receiving position A to approach the winding shaft 31, and can control the material receiving portion 102 or the upper winding portion 103 to move in the opposite direction from the material receiving position A to the intermediate position C to move away from the winding shaft 31;

[0100] The rotating mechanism can control the upper roll portion 103 to rotate horizontally, so as to control the upper roll portion 103 to switch between the intermediate position C and the upper roll position D.

[0101] Specifically, the above-mentioned linear drive mechanism includes a linear guide rail 11 and a slide 112. The slide 112 can be relatively slidably arranged on the linear guide rail 114 and can move horizontally along the linear guide rail 114; the rotating mechanism includes a turntable 113 and a power mechanism 111. The turntable 113 can be relatively rotatably arranged on the slide 112. The power mechanism 111 can drive the turntable 113 to rotate horizontally. The material receiving part 102 and the upper rolling part 103 are both arranged on the turntable 113 to control the rotation switching station through the turntable 113.

[0102] During specific implementation, the power mechanism 111 can adopt a rotary reducer, which is connected to the unloading rotary drive shaft, and the unloading rotary drive shaft is connected to the turntable 113, which can drive the turntable 113 to rotate horizontally to control the material receiving part 102 to transfer from the docking position A to the unloading position B, or control the material receiving part 102 to transfer from the unloading position B to the docking position A.

[0103] In a specific embodiment, the turntable 113 and the slide 112 are rotatably connected via a cross-cylindrical roller turntable bearing. The cross-cylindrical roller turntable bearing is located between the upper seat of the blanking rotary bearing and the base of the blanking rotary bearing. Alternatively, in other specific embodiments, a tapered roller bearing may be used.

[0104] In a preferred embodiment, a height adjustment mechanism is provided at the bottom of the workstation conversion portion 101 , so that the horizontal height of the workstation conversion portion 101 relative to the ground can be adjusted through the height adjustment mechanism.

[0105] In a specific implementation, the linear guide rail 114 is fixedly mounted on the base 1145. Two linear guide rails 114 are generally arranged in parallel on the base 1145. In addition, a plurality of height adjustment mechanisms are arranged side by side on both sides of the base 114.

[0106] Specifically, see Figure 3 The height adjustment mechanism includes a first mounting seat 1141 and a second mounting seat 1142 located below the first mounting seat 1141. The second mounting seat 1142 is anchored to the ground via multiple long bolts 1143. The first mounting seat 1141 is provided with one or more adjustment bolts 1144, the bottom of each adjustment bolt 1144 abutting against the second mounting seat 1142. Thus, the height of the first mounting seat 1141 can be adjusted by adjusting the bolts 1144, thereby adjusting the height of the workstation conversion unit 101 relative to the ground. This allows the height of the upper winding core shaft 134 to align with the outlet of the target position of the box 141, accurately receiving the empty barrel 143 and accurately docking it with the slitting machine reel 31. Furthermore, this height adjustment mechanism also allows the height of the material receiving unit 102, described below, to be adjusted, allowing it to accurately dock with the slitting machine reel 31.

[0107] The first embodiment of the present invention provides a self-handling device for loading and unloading materials, comprising the loading device described above, and a material receiving portion 102. Specifically, the self-handling device for loading and unloading materials comprises a material receiving portion 102, a coiling portion 103, and a station conversion portion 101. Specifically,

[0108] The material receiving portion 102 can move to the docking position A to receive the material roll 32 on the reel 31;

[0109] The upper winding portion 103 can be moved to the docking position A to provide an empty barrel 143 for the reel 31. The empty barrel 143 is a core shaft for winding the material roll 32.

[0110] The station conversion unit 101 can control the material receiving unit 102 to switch between the docking position A and the material unloading position B, and can control the winding unit 103 to switch between the docking position A and the winding position D.

[0111] Specifically:

[0112] The linear drive mechanism in the work station conversion part 101 can control the material receiving part 102 / upper winding part 103 to move linearly from the middle position C to the material receiving position A to approach the winding shaft 31, and can control the material receiving part 102 / upper winding part 103 to move in the opposite direction from the material receiving position A to the middle position C to move away from the winding shaft 31.

[0113] The rotating mechanism in the work station conversion part 101 can control the horizontal rotation of the material receiving part 102 and the upper rolling part 103 to control the material receiving part 102 to switch between the middle position C and the material unloading position B, or control the upper rolling part 103 to switch between the middle position C and the upper rolling position D.

[0114] Specifically, when the material roll 32 on the reel 31 of the slitting machine is formed and needs to be unloaded, the work station conversion unit 101 controls the material receiving unit 102 to move to the docking position A to receive the material roll 32 on the reel 31, and controls the material receiving unit 102 to transfer from the docking position A to the unloading position B, so as to facilitate the AGV (automatic guided vehicle) or other unloading device at this position to unload or manually unload; after unloading is completed, the work station conversion unit 101 controls the material receiving unit 102 to return from the unloading position B to the docking position A to continue unloading or wait for unloading.

[0115] In addition, after the work station conversion part 101 controls the material receiving part 102 to transfer from the docking position A to the material unloading position B to complete the unloading, it also controls the upper winding part 103 to move to the docking position A to provide an empty barrel 143 for the winding shaft 31 for forming the next batch of material rolls 32; after the winding is completed, the work station conversion part 101 controls the upper winding part 103 to move to the upper winding position D to prepare the next batch of empty barrels 143.

[0116] It can be seen that in the material loading and unloading self-processing device, the material roll 32 on the winding shaft 31 is received through the material receiving part 102, the empty material barrel 143 is provided for the winding shaft through the winding part 103, and the work station conversion part 101 automatically switches the work station between the material receiving part 102 and the winding part, thereby eliminating the need for manual handling and unloading of materials and manual handling of winding, which is conducive to realizing automatic winding and unloading, reducing labor costs and improving production efficiency.

[0117] Moreover, when using the self-handling device for loading and unloading, the self-handling device for loading and unloading is located between the slitting machine reel 31 and the AGV, and can transfer the material roll 32 on the reel 31 to the unloading position B for the AGV to automatically unload. Since the position of the unloading position B is fixed, it is convenient for the AGV to capture and receive the material, which is conducive to reducing the difficulty of unloading and improving the efficiency and accuracy of unloading.

[0118] The loading and unloading self-handling device can be used for auxiliary unloading of lithium battery slitting machines, ensuring accurate docking of coils with AGVs and achieving smooth unloading. It is also conducive to realizing automated unloading, reducing labor costs and improving production efficiency.

[0119] See Figure 1In a specific implementation, the material receiving unit 102 uses a material receiving mandrel 124 to receive the material roll 32. One end of the material receiving mandrel 124 is mounted on the turntable 113 of the station conversion unit 101, and the other end is coaxially connected to the reel 31 to receive the material roll 32 that is moved down from the reel 31. The material roll 32 can be moved down from the reel 31 by the slitting fork 33, or manually or by other means.

[0120] Furthermore, in order to ensure that the material roll 32 can be stably sleeved on the material splicing core shaft 124, an elastic latch is provided at the outer end of the material splicing core shaft 124 close to the reeling shaft 31 to prevent the material roll 32 from falling off.

[0121] For example, see Figure 4 The elastic latch includes a limiting portion 1241, a control portion, and an elastic portion 1243. The limiting portion 1241 is retractably disposed within a first mounting hole on the circumferential side wall of the splicing core shaft 124; the control portion is capable of controlling the limiting portion 1241 to retract into the first mounting hole; and the elastic portion 1243 is capable of controlling the limiting portion 1241 to extend out of the first mounting hole.

[0122] Preferably, the control portion of the elastic latch is a wedge-shaped piece 1242 ′, and the limiting portion 1241 is provided with an adjustment position adapted to the wedge-shaped piece 1242 ′ (eg, a wedge-shaped hole with a larger radial size, or other structures).

[0123] When the material splicing core shaft 124 is coaxially docked with the winding shaft 31, the wedge 1242' is gradually pressed into the material splicing core shaft 124 along the axial direction by the winding shaft 31, so that the limiting portion 1241 is gradually retracted into the material splicing core shaft 124, so that the material roll 32 on the winding shaft 31 can be smoothly transferred to the material splicing core shaft 124.

[0124] When the slide 112 moves along the linear guide rail 114 to move the material receiving core shaft 124 away from the winding shaft 31, the material receiving core shaft 124 moves away from the winding shaft 31. Figure 5 When the docking position A in the middle reaches the middle position C, under the action of the elastic portion 1243, the limiting portion 1241 automatically pops out to axially limit the material roll 32 on the docking material core shaft 124 to prevent it from accidentally falling off.

[0125] It should be noted that, please refer to Figure 4When the material splicing core shaft 124 gradually approaches the winding shaft 31, the end of the winding shaft 31 axially squeezes the wedge 1242', and the wedge 1242' moves to the left under the action of the axial force F1, and squeezes the adjustment position of the limiting portion 1241 (for example, the lower side slope of the wedge-shaped hole). As a result, the limiting portion 1241 gradually retracts into the material splicing core shaft 124 under the action of the radial force F2, so that the side wall of the material splicing core shaft 124 has a smooth surface, which facilitates the smooth transfer of the material roll 32 from the winding shaft 31 to the material splicing core shaft 124. When the material splicing core shaft 124 gradually moves away from the winding shaft 31, under the restoring force of the elastic part 1243 (generally a spring), the wedge 1242' moves to the right, and the limiting part 1241 gradually extends out of the material splicing core shaft 124 along the radial direction of the core shaft, thereby playing an axial limiting role on the material roll 32 on the material splicing core shaft 124, preventing the material roll 32 from accidentally falling off the material splicing core shaft 124.

[0126] See Figure 1 In a specific embodiment, the material receiving section 102 further includes a second connecting beam 123 and a third drive mechanism. The second connecting beam 123 includes two or more material receiving mandrels 124 arranged axially in sequence. Each material receiving mandrel 124 is perpendicularly connected to the second connecting beam 123, forming an automatic material receiving fork. The third drive mechanism can control the second connecting beam 123 to rotate the material receiving mandrels 124 from the receiving state to the unloading state, and can also control the second connecting beam 123 to rotate the material receiving mandrels 124 from the unloading state to the receiving state. When in the receiving state, the material receiving mandrel 124 can coaxially dock with the reel 31. When in the unloading state, the material receiving mandrel 124 can unload the material roll 32, for example, by an AGV.

[0127] Specifically, the third driving mechanism includes a second driving shaft 122 and a second motor 121. The second driving shaft 122 is vertically connected to the second connecting beam 123; the second motor 121 can drive the second driving shaft 122 to rotate around its own axis, thereby controlling the second connecting beam 123 to rotate with the material receiving core shaft 124 in a vertical plane through the second driving shaft 122. For example, Figure 1 As shown in the figure, when receiving the material, the second connecting beam 123 is in the receiving state, that is, the vertical state, so that the multiple receiving core shafts 124 correspond one to one with the multiple winding shafts 31 and are coaxially docked; when unloading the material, the second connecting beam 123 is in the unloading state, that is, the horizontal state, to facilitate the AGV car to receive and transport the material rolls.

[0128] In specific implementation, the second motor 121 may also adopt other driving devices, such as a cylinder driven rotating structure. The second drive shaft 122 is rotatably mounted on the turntable 113 through a tapered roller bearing and a support, and is in transmission connection with the second motor 121.

[0129] In a preferred embodiment, Figure 1 and Figure 2 As shown in , the loading and unloading positions D and B are located on either side of the workstation conversion unit 101. Furthermore, the loading and unloading positions D, docking position A, and unloading position B are arranged circumferentially around the rotation center of the workstation conversion unit 101, with their circumferential angles all being 90°. As a result, the process of the material receiving unit 102 receiving the material roll at docking position A and the process of the loading and unloading unit 103 receiving the empty barrel 143 at the loading and unloading position D do not affect each other and can proceed simultaneously. Furthermore, the process of the material receiving unit 102 unloading the material at the unloading position B and the process of the loading and unloading unit 103 loading the empty barrel 143 onto the take-up shaft 31 at docking position A do not affect each other and can proceed simultaneously. This helps reduce production time and improve production efficiency.

[0130] It should be noted that the driving devices used in this article can all be electric cylinders, pneumatic cylinders, or hydraulic cylinders; the reducer can be a pneumatic cylinder rotation mechanism or a hydraulic cylinder rotation mechanism; the core shaft can be a pneumatic shaft or an ordinary hollow shaft with automatic limit.

[0131] In summary, the loading and unloading self-handling device provided in the first embodiment of the present invention can realize the following working process:

[0132] Splicing roll: the slide 112 moves along the positive direction of the x-axis to the receiving roll 31 (3s to 7s, preferably 5s), and the slitting machine fork 33 shifts the roll 32 to the splicing core shaft 124 (8s to 12s, preferably 10s);

[0133] Roll core feeding: Slide 112 moves back along the x-axis, turntable 113 rotates 90° clockwise around the z-axis, material receiving unit 102 (with material roll 32) rotates 90° around the x-axis, and the upper roll unit (with upper roll core shaft 134) rotates 90° around the y-axis; (13s to 17s, preferably 15s)

[0134] Upper winding core: The slide 112 moves in the positive direction along the x-axis and docks with the differential shaft (3s to 7s, preferably 5s). The clamp 135 pushes the empty barrel 143 to the differential shaft of the slitter at one time (5s to 30s, preferably 20s / 10s). The slide 112 moves back in the reverse direction along the x-axis (3s to 7s, preferably 5s).

[0135] The above 3 steps take about 55 seconds in total;

[0136] Unloading coils: The coils can be unloaded automatically by means of a material fork, which pushes the coils 32 to the AGV in sequence (one coil at a time, for example, three times in total); or the coils can be unloaded by an external AGV;

[0137] Mandrel preparation: The turntable 113 rotates 90° counterclockwise around the z-axis, and the pusher pushes the empty material barrels 143 onto the upper winding mandrel 134 in sequence (for example, 3 times in total).

[0138] At this point, the loading and unloading self-handling device has completed unloading and is ready for use.

[0139] In summary, please see Figure 5 and Figure 6 The first embodiment of the present invention further provides a slitting and unloading self-processing system, which includes a slitting machine 3 and the above-mentioned loading and unloading self-processing device 1. The slitting machine 3 is a roller-pressed slitting machine that can automatically unwind, rewind, and cut the tape, and is used in the lithium battery electrode slitting process.

[0140] Specifically, the slitting machine 3 is provided with a winding shaft 31 and a fork 33. The winding shaft 31 can wind the slit electrodes to obtain a material roll 32, and the fork 33 is used to control the axial movement of the material roll 32; the docking position A of the loading and unloading self-processing device 1 is located on the axial outside of the winding shaft 31.

[0141] In specific implementation, a set of loading and unloading self-processing device 1 can be used in conjunction with two or more roller-pressing and slitting machines for production (laying ground rails). Moreover, in specific implementation, the material can be automatically unloaded by the material fork, or the external AGV can grab and unload the material. Figure 6 As shown in FIG, each set of roller-pressing and slitting machines is provided with, in addition to the slitting machine 3, a roller-pressing main machine 4, an unwinding mechanism 5, a first vacuum cleaner 6, a hydraulic station 7, an electric cabinet 8, and a second vacuum cleaner 9. A roller-changing trolley 2 is provided between the roller-pressing main machines 4 of the two roller-pressing and slitting machines.

[0142] During the actual production process, the roller-pressing and slitting integrated machine is responsible for unfolding the coated material roll, rolling it to the process thickness, slitting it to the process width, and winding it neatly on two axes. After the roll is wound into place, it is automatically cut and the tail is manually glued to complete the winding of the electrode; the loading and unloading self-handling device 1 cooperates with the winding shaft 31 inside the slitting machine 3 to automatically collect the wound and cut material roll 32 to the material receiving part 101, and after completing the pushing of the empty barrel 143, the slitting machine 3 can continue production. The whole process takes 1 minute, and the efficiency is increased by 30 times.

[0143] In specific implementation, the equipment height of the above-mentioned slitting and unloading self-processing system is about 4.6m, and the recommended ceiling height is 5.5m.

[0144] Second specific embodiment

[0145] The second embodiment of the present invention provides a feeding device, which is different from the feeding device in the first embodiment only in the specific structure of the clamping claw 135. Figure 7 The clamping jaw 135 can be opened and closed by a cylinder.

[0146] Third specific embodiment

[0147] The third embodiment of the present invention provides a self-handling device for loading and unloading materials, which differs from the self-handling device for loading and unloading materials in the first embodiment only in that: Figure 8 In order to enhance the bending strength of the splicing core shaft 124 , two or more second connecting beams 123 are arranged side by side at its connecting end.

[0148] Fourth specific embodiment

[0149] The fourth embodiment of the present invention provides a self-handling device for loading and unloading materials, which differs from the self-handling device for loading and unloading materials in the first embodiment only in that: Figure 9 In the elastic latch arranged at the outer end of the material receiving core shaft 124, the control part is a smooth protrusion 1242", and the smooth protrusion 1242" is telescopically arranged in the second mounting hole of the circumferential side wall of the material receiving core shaft 124, and the end of the winding shaft 31 is provided with a tapered end hole 311 for squeezing the smooth protrusion 1242".

[0150] That is, the elastic latch includes a limiting portion 1241, a smooth protrusion 1242" and an elastic portion 1243. When the material splicing core shaft 124 gradually approaches the winding shaft 31, the side wall of the end hole 311 of the winding shaft 31 squeezes the smooth protrusion 1242", so that it is gradually hidden in the material splicing core shaft 124 in the radial direction, thereby causing the limiting portion 1241 to gradually retract into the material splicing core shaft 124, so that the side wall of the material splicing core shaft 124 has a smooth surface, which facilitates the smooth transfer of the material roll 32 from the winding shaft 31 to the material splicing core shaft 124. When the material splicing core shaft 124 gradually moves away from the winding shaft 31, under the restoring force of the elastic portion 1243 (generally a spring), the smooth protrusion 1242" and the limiting portion 1241 gradually extend out of the material splicing core shaft 124 in the radial direction, thereby axially limiting the material roll 32 on the material splicing core shaft 124 to prevent the material roll 32 from accidentally falling off the material splicing core shaft 124.
