Description

Technical Field

[0001] The utility model belongs to the technical field of battery manufacturing, and in particular relates to a discharge safety lock structure. Background Art

[0002] The pole piece is one of the core parts of lithium-ion batteries. It is mainly made through processes such as coating, rolling and slitting. Among them, the slitting operation is to cut the pole piece into strips of various specifications by a slitting machine for subsequent winding or stacking. After the pole piece is slit, the strip is usually wound on a reel. The pole piece is rolled into a roll. In the actual production process, due to the large number and high quality of the rolls, and the high position of the reel, it is difficult for operators to unload the rolls manually. The rolls are generally unloaded by unloading devices.

[0003] The existing unloading device usually includes a vehicle body, on which is provided an unloading arm for hanging the material roll. When unloading the material roll, the operator moves the vehicle body to one side of the winding shaft so that the unloading arm docks with the winding shaft, and the material roll moves from the winding shaft to the unloading arm. The operator can transfer the material roll by pushing the vehicle body.

[0004] However, when the mass of the material roll is large, there is still a risk that the material roll will slip from the unloading arm, which can easily cause damage to the electrode and may cause a safety accident in which the material roll slips and injures the operator. Utility Model Content

[0005] In order to solve the shortcomings of the prior art, the utility model provides a discharge safety lock structure. When the lock tongue drives the latch to enter the discharge arm, the material roll can be discharged from the reel shaft to the discharge arm, and the material roll can be conveniently transported. When the lock tongue drives the latch to penetrate the discharge arm, the latch can prevent the material roll from sliding off, which is conducive to reducing the risk of the material roll sliding off, and reducing the situation of damage to the pole piece and safety accidents caused by the material roll sliding off and the operator being injured by the impact.

[0006] The technical effects to be achieved by the utility model are achieved through the following technical aspects:

[0007] In the first aspect, the utility model provides a unloading safety lock structure, including a latch for blocking a material roll from sliding off, the latch being passed through a unloading arm and slidably connected to the unloading arm; a first pair of joints being provided on the unloading arm, a receiving hole being provided on the first joint; and a locking tongue, a rotating shaft being provided between the locking tongue and the hole wall of the receiving hole, the locking tongue being rotatably provided in the receiving hole around the rotating shaft, wherein the connecting end is rotatably provided on the latch and is used for the sliding of the latch, and a resetting member for driving the locking tongue to return to its original position after rotation is provided between the locking tongue and the first pair of joints.

[0008] In some implementations, the locking tongue is provided with a sliding hole on the connecting end, the latch pin is inserted into the sliding hole, and the latch pin is provided with an anti-detachment component for limiting the latch pin from detaching from the sliding hole.

[0009] In some implementations, the latch includes a material blocking end for preventing the material roll from sliding off, and the anti-slip assembly includes a limiting rod and a limiting ring respectively arranged on both sides of the locking tongue, and the limiting ring is located between the material blocking end and the locking tongue.

[0010] In some implementations, an elastic member is sleeved on the latch pin, and the elastic member is located between the limiting ring and the locking tongue, and abuts against the limiting ring and the locking tongue respectively.

[0011] In some implementations, the limiting ring is a retaining spring, and the retaining spring is clamped on the latch.

[0012] In some implementations, the locking tongue includes a rotating end, and when the locking tongue rotates, the rotating end extends out of or enters the receiving hole.

[0013] In some implementations, the rotating end includes a guide surface, the second pair of joints pushes the rotating end along the guide surface, and the guide surface is a curved surface.

[0014] In some implementations, a second pair of joints is further included, wherein the second pair of joints is disposed on the reel, and when unloading, the second pair of joints is connected to the first pair of joints.

[0015] In some implementations, a docking groove is formed on the second docking head, a hooking portion is formed on the first docking head, and the second docking head is engaged with the hooking portion in the docking groove.

[0016] In some implementations, a guide sleeve is provided on the outer side of the latch, the guide sleeve is provided on the discharge arm, and the latch is slidably provided in the guide sleeve.

[0017] In summary, the utility model has at least the following benefits:

[0018] The utility model provides a unloading safety lock structure, in which a pole piece is wound around a reel to form a material roll. When the unloading arm approaches the reel for unloading, the lock tongue is rotated, and the lock tongue rotates around the rotating shaft, and the connecting end drives the latch to remain retracted into the unloading arm, and the material roll is translated from the reel to the unloading arm. The lock tongue is released, and the reset member drives the lock tongue to rotate and reset. The lock tongue drives the latch at the connecting end to pass through the unloading arm. The end of the latch passes through the unloading arm and protrudes from the surface of the unloading arm to prevent the material roll from sliding off, and the material roll is unloaded. The unloading arm can block the material roll through the latch, so as to solve the problem that the existing material roll is easy to slide off the unloading arm during transportation, thereby reducing the situation of damage to the pole piece due to the slipping of the material roll, and the safety accident of the material roll falling and injuring the operator, thereby improving the convenience of material roll unloading and transportation operations.

[0031] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1:

[0034] Please refer to the attached Figure 1 The utility model provides a discharge safety lock structure, comprising a first pair of joints 2, which are arranged on a discharge arm 5. Specifically, the discharge arm 5 is arranged horizontally, and the first pair of joints 2 are located at one end of the discharge arm 5 along the horizontal direction. In a preferred embodiment, the first pair of joints 2 and the discharge arm 5 are detachably connected. Furthermore, the first pair of joints 2 and the discharge arm 5 are preferably, but not limited to, assembled by bolts.

[0035] A receiving hole 21 is formed through the first pair of joints 2 on one side away from the discharge arm 5. The first pair of joints 2 is connected to the inside of the discharge arm 5 at the receiving hole 21. The first pair of joints 2 is rotatably provided with a locking tongue 3 in the receiving hole 21. The locking tongue 3 is specifically L-shaped. A rotating shaft 12 is provided between the locking tongue 3 at the bend and the hole wall of the receiving hole 21. The locking tongue 3 is rotatably connected to the first pair of joints 2 through the rotating shaft 12. The locking tongue 3 includes a connecting end 31, and the connecting end 31 is located inside the discharge arm 5.

[0036] A reset member 32 is provided between the lock tongue 3 and the first pair of joints 2 for driving the lock tongue 3 to reset after rotation. In a preferred embodiment, the reset member 32 is a torsion spring, which is respectively connected to the lock tongue 3 and the hole wall of the accommodating hole 21, and pushes the lock tongue 3 to rotate around the rotating shaft 12. The torsion spring can drive the lock tongue 3 to reset to the initial state.

[0037] The locking tongue 3 is provided with a latch 1 at the connection end 31, and the latch 1 is rotatably connected to the locking tongue 3. The end of the latch 1 away from the connection end 31 passes through the discharge arm 5 and is slidably connected to the discharge arm 5. The latch 1 is specifically arranged vertically. In a preferred embodiment, a mounting seat 14 is arranged between the latch 1 and the discharge arm 5. The mounting seat 14 is mounted on the discharge arm 5. A guide sleeve 13 is penetrated in the mounting seat 14. The guide sleeve 13 is a vertically arranged cylinder. The latch 1 is penetrated in the guide sleeve 13 and is slidably connected to the guide sleeve 13. The latch 1 can slide into or out of the interior of the discharge arm 5 along the guide sleeve 13. When the latch 1 passes through the guide sleeve 13 to slide out of the interior of the discharge arm 5, it can prevent the material roll 7 from sliding off.

[0038] When the material roll 7 is unloaded, the unloading arm 5 is connected with the reel shaft 6, pushing the lock tongue 3 to rotate around the rotating shaft 12 in the accommodating hole 21, and the rotation of the lock tongue 3 drives the latch 1 to slide in the guide sleeve 13 to penetrate into the interior of the unloading arm 5, and the material roll 7 wound at the reel shaft 6 can move parallel to the unloading arm 5. When the unloading arm 5 carries the material roll 7 for turnover, the lock tongue 3 is released, and the lock tongue 3 is reset to the initial state through the reset member 32. The lock tongue 3 rotates and drives the latch 1 to slide out of the interior of the unloading arm 5 in the guide sleeve 13. The latch 1 blocks the material roll 7 from sliding, thereby improving the safety of the unloading of the material roll 7 and solving the problem of damage to the pole piece caused by the sliding of the material roll 7 and the problem of the material roll 7 falling and injuring the operator.

[0039] Embodiment 2:

[0040] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the latch 1 of the utility model, see Figure 2 .

[0041] The locking tongue 3 of this embodiment is provided with a sliding hole 311 on the connecting end 31 . Specifically, the sliding hole 311 is a waist-shaped hole. The latch pin 1 is inserted into the sliding hole 311 and can slide along the sliding hole 311 .

[0042] The latch 1 includes a material blocking end 114, which slides in the guide sleeve 13. When the material blocking end 114 slides out of the guide sleeve 13 to the outside of the discharge arm 5, the latch 1 blocks the material roll 7 from sliding off at the material blocking end 114. The latch 1 is provided with an anti-slip assembly. In a preferred embodiment, the anti-slip assembly includes a limit rod 111. Specifically, the limit rod 111 is a horizontally arranged round rod and is provided with two. The two limit rods 111 are symmetrically distributed on both sides of the latch 1 along the axis direction of the latch 1. It can be understood that this is not a limitation on the specific number of limit rods 111, and technicians in the relevant field can replace them on this basis. The limit rod 111 is located at the bottom of the lock tongue 3. When the lock tongue 3 drives the latch 1 to slide into the discharge arm 5 through the guide sleeve 13, the lock tongue 3 presses down the limit rod 111, and the limit rod 111 can limit the latch 1 from disengaging from the slide hole 311.

[0043] A limiting ring 112 is sleeved on the latch 1. In a preferred embodiment, the limiting ring 112 is a retaining spring, which is clamped on the latch 1 and located between the material blocking end 114 and the lock tongue 3, so as to facilitate disassembly and assembly. The limiting ring 112 is located at the top of the lock tongue 3. When the lock tongue 3 drives the material blocking end 114 to slide out of the discharge arm 5 through the guide sleeve 13, the lock tongue 3 pushes the limiting ring 112 upward, and the limiting ring 112 can limit the latch 1 from being separated from the slide hole 311. In some specific embodiments shown, an elastic member 113 is provided between the limiting ring 112 and the lock tongue 3. The elastic member 113 is preferably, but not limited to, a spring. The elastic member 113 is sleeved on the latch 1, and one end of the elastic member 113 along the compression direction abuts against the limiting ring 112, and the other end abuts against the corresponding end of the lock tongue 3. When the locking tongue 3 drives the material blocking end 114 to slide out to the outside of the unloading arm 5 through the guide sleeve 13, the elastic member 113 is in a compressed state, and the limiting ring 112 abuts against the corresponding side of the guide sleeve 13. The elastic member 113 has a certain auxiliary rebound effect and can reduce the influence of the angle change between the locking tongue 3 and the latch 1 on the lifting and lowering movement of the latch 1.

[0044] After the lock tongue 3 rotates, it presses down the limit rod 111, and the lock tongue 3 drives the material blocking end 114 to enter the guide sleeve 13. After the lock tongue 3 is reset by the reset member 32, the lock tongue 3 pushes up the elastic member 113 and the limit ring 112, the elastic member 113 is compressed, and the material blocking end 114 slides out of the guide sleeve 13 to the outside of the unloading arm 5. The pin 1 blocks the sliding material roll 7, which is conducive to improving the convenience of installation.

[0045] Embodiment 3:

[0046] The difference between this embodiment and embodiment 1 is that the unloading safety lock structure of the utility model further includes a second pair of joints 4, which are installed on the reel 6 and are arranged corresponding to the first pair of joints 2. When unloading, the second pair of joints 4 fit with the corresponding surface of the first pair of joints 2 to achieve docking. See Figure 3 and Figure 4 .

[0047] The second pair of joints 4 is provided with a docking groove 41, specifically, the docking groove 41 is an annular groove, and the first pair of joints 2 is provided with a hooking portion 22, which is adapted to the docking groove 41, so that the hooking portion 22 is engaged with the second pair of joints 4 in the docking groove 41. During unloading, the vehicle body easily drives the unloading arm 5 to move backward, and the first pair of joints 2 is engaged with the docking groove 41 of the second pair of joints 4 through the hooking portion 22, and the unloading arm 5 and the winding shaft 6 are mutually engaged, ensuring that the unloading arm 5 will not move backward during the unloading process, and further ensuring the safety of unloading when the winding shaft 6 is high.

[0048] The lock tongue 3 includes a rotating end 33, which is located at the opening of the receiving hole 21. When the lock tongue 3 rotates, the rotating end 33 enters or leaves the receiving hole 21. The lock tongue 3 is connected to the reset member 32 at the rotating end 33. When the lock tongue 3 is in the initial state, the rotating end 33 protrudes to one side of the first pair of joints 2. When the second pair of joints 4 is docked with the first pair of joints 2, the first pair of joints 2 moves upward through the discharge arm 5, and the second pair of joints 4 pushes the rotating end 33 into the receiving hole 21, so that the lock tongue 3 can rotate automatically.

[0049] In a preferred embodiment, the rotating end 33 of the locking tongue 3 includes a guide surface 331, which is an arc surface. The second pair of joints 4 moves along the guide surface 331 to push the rotating end 33 into the accommodating hole 21, which is beneficial to improve the smoothness of the rotation of the locking tongue 3.

[0050] When the material roll 7 is unloaded onto the unloading arm 5, the first pair of joints 2 moves away from the second pair of joints 4, the rotating end 33 disengages from the limit of the second pair of joints 4, the reset member 32 drives the rotating end 33 to rotate and leave the accommodating hole 21, and the locking tongue 3 at the connecting end 31 drives the blocking end 114 of the latch 1 to pass through the guide sleeve 13 to the outside of the unloading arm 5, and the latch 1 extends out of the guide sleeve 13 to prevent the material roll 7 from sliding off.

[0051] When the second pair of joints 4 and the first pair of joints 2 move relative to each other, the second pair of joints 4 pushes the rotating end 33 to move, and the reset member 32 drives the lock tongue 3 to reset, so that the bolt 1 achieves self-locking, which is beneficial to improving the convenience of operation.
