Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of battery film production technology, and more specifically, to a battery film roll transfer device. Background Technology

[0002] In the battery manufacturing industry, battery film is a key component, and its quality directly affects battery performance and safety. With the rapid development of the battery industry, the demand for battery film is constantly increasing, making the efficient and safe transfer of battery film rolls an important task in the production process.

[0003] Traditional battery film roll transfer methods primarily rely on manual labor or simple trolleys. However, the weight of battery film rolls makes manual handling extremely difficult, consuming significant manpower and time, resulting in low transfer efficiency, increasing worker fatigue, and posing safety hazards. Furthermore, manual or trolley handling is highly susceptible to damage such as wrinkles and scratches due to operational instability and a lack of professional protective measures. This damage can lead to a series of problems in subsequent battery production, such as affecting the internal structural stability of the battery and reducing its charge and discharge performance, ultimately resulting in decreased battery product quality and increased production costs. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a battery film roll transfer device, which solves the technical problems of the heavy weight of the battery film, low efficiency of manual handling, and easy damage to the battery film in the prior art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a battery film roll transfer device for transferring battery film located at a workstation, comprising:

[0006] Mobile frame;

[0007] A lifting frame is vertically slidably mounted on the movable frame, and the lifting frame has a channel; after the lifting frame slides down vertically, it approaches the workstation, allowing the battery film to pass through the channel;

[0008] The first clamping tooth is horizontally slidably disposed within the channel;

[0009] The second clamping tooth is horizontally slidably disposed within the channel; after the second clamping tooth and the first clamping tooth slide horizontally, they move closer to or further apart from each other, forming a clamping space between the second clamping tooth and the first clamping tooth; the battery film roll is located within the clamping space.

[0010] For example, in a battery film roll transfer device provided in at least one embodiment of this disclosure, the length directions of the first clamping tooth and the second clamping tooth are both parallel to the axis of the battery film roll.

[0011] For example, in a battery film roll transfer device provided in at least one embodiment of this disclosure, the number of the first clamping teeth and the number of the second clamping teeth are both several; the several second clamping teeth and the several first clamping teeth are distributed at intervals.

[0012] After the second tooth slides close to the first tooth, the second tooth enters the gap between two adjacent first teeth.

[0013] For example, in a battery film roll transfer device provided in at least one embodiment of this disclosure, the ends of the second clamping tooth and the first clamping tooth that are close to each other both have chamfers.

[0014] For example, in a battery film roll transfer device provided in at least one embodiment of this disclosure, the second gripping tooth has a first mounting portion near the end of the first gripping tooth, and the first gripping tooth has a second mounting portion near the end of the second gripping tooth, and further includes:

[0015] A plurality of abutting wheels are provided, and the plurality of abutting wheels are respectively rotatably disposed on the first mounting part and the second mounting part.

[0016] For example, in a battery film roll transfer device provided in at least one embodiment of this disclosure, both the second gripping tooth and the first gripping tooth have an abutting arc surface; the abutting arc surface is used to abut against the battery film.

[0017] For example, a battery film roll transfer device provided in at least one embodiment of this disclosure further includes:

[0018] A sliding frame is horizontally slidably disposed on the lifting frame and located within the channel; a plurality of second clamping teeth and first clamping teeth are respectively horizontally slidably disposed within the channel via two of the sliding frames.

[0019] For example, a battery film roll transfer device provided in at least one embodiment of this disclosure further includes:

[0020] A bidirectional lead screw is rotatably mounted on the lifting frame; the sliding frame is threadedly connected to the bidirectional lead screw.

[0021] A rotation drive component is provided on the lifting frame to drive the bidirectional lead screw to rotate, thereby causing the sliding frame to slide horizontally.

[0022] For example, a battery film roll transfer device provided in at least one embodiment of this disclosure further includes:

[0023] A lifting drive component is mounted on the movable frame and is used to drive the lifting frame to move up and down.

[0024] For example, a battery film roll transfer device provided in at least one embodiment of this disclosure further includes:

[0025] The casters are mounted on the lower surface of the mobile frame; the mobile frame moves on the ground via the casters.

[0026] The beneficial effects of the embodiments disclosed herein are as follows:

[0027] This disclosure utilizes the mobility of the mobile frame, the lifting function of the lifting frame, and the cooperation between the second and first clamping teeth to quickly and accurately complete the clamping, lifting, and transfer operations of the battery film roll. This significantly shortens the transfer time of the battery film roll between different workstations, improving the efficiency of the entire battery production process while reducing unnecessary contact and collisions with external objects. This effectively reduces the risk of battery film damage, ensures battery film quality, and ultimately improves the pass rate and performance stability of battery products.

[0033] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

Therefore, they should not be construed as limitations on this disclosure.

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] like Figures 1-3The diagram illustrates a battery film roll transfer device according to an embodiment of the present disclosure, used to transfer a battery film roll 2 located at workstation 1. The device includes a movable frame 3; a lifting frame 4 vertically slidably disposed on the movable frame 3, the lifting frame 4 having a channel 401; the lifting frame 4 slides vertically down and approaches workstation 1, allowing the battery film roll 2 to pass through the channel 401; a first clamping tooth 5 is horizontally slidably disposed within the channel 401; a second clamping tooth 6 is horizontally slidably disposed within the channel 401; the second clamping tooth 6 and the first clamping tooth 5 slide horizontally and then approach or move away from each other, forming a clamping space between the second clamping tooth 6 and the first clamping tooth 5; the battery film roll 2 is located within the clamping space.

[0040] For example, such as Figure 1 As shown, the movable frame 3 is a trolley-like frame structure that can move freely on the workshop floor. The lifting frame 4 is vertically slidably connected to the movable frame 3 via vertical guide rails. The channel 401 inside the lifting frame 4 is a space that runs through the frame, and its size and shape allow the battery film roll 2 to pass through smoothly.

[0041] Both the first clamping tooth 5 and the second clamping tooth 6 are slidably installed inside the channel 401 via a horizontal guide rail and slider mechanism, and can slide freely in the horizontal direction.

[0042] Specifically, when the battery film roll 2 located at workstation 1 needs to be transferred within the workshop, the operator first pushes the movable frame 3 to the side of workstation 1 and aligns the lifting frame 4 with the battery film roll 2. Next, the operator drives the lifting frame 4 to slide vertically down the guide rail on the movable frame 3, approaching the battery film roll 2 at workstation 1, until the battery film roll 2 completely passes through the channel 401 of the lifting frame 4. Afterwards, the operator controls the first clamping tooth 5 and the second clamping tooth 6 to slide in opposite directions along the horizontal guide rail. As the first clamping tooth 1 and the second clamping tooth 6 move, the distance between them gradually decreases, ultimately securing the battery film roll 2 stably.

[0043] After confirming that the battery film roll 2 is securely clamped, the operator raises the lifting frame 4. During the raising process, the battery film roll 2 moves away from the workstation 1 along with the movement of the lifting frame 4. Then, the operator pushes the movable frame 3 to move the device clamping the battery film roll 2 to the target position, completing the position transfer of the battery film roll 2.

[0044] Once the battery film roll 2 is moved to the designated position, the lifting frame 4 is lowered first, so that the battery film roll 2 is close to another station 1 on the ground. Then, the first clamping tooth 5 and the second clamping tooth 6 slide horizontally in opposite directions to move away from each other, so that the battery film roll 2 is removed from the transfer equipment. Finally, the lifting frame 4 is raised to complete the transfer of the battery film roll 2.

[0045] The advantage lies in the fact that, compared to traditional manual handling methods, the mobility of the mobile frame 3, the lifting function of the lifting frame 4, and the cooperation between the second clamping tooth 6 and the first clamping tooth 5 enable the clamping, lifting, and transfer operations of the battery film roll 2 to be completed quickly and accurately. This significantly shortens the transfer time of the battery film roll 2 between different workstations 1, improving the efficiency of the entire battery production process while reducing unnecessary contact and collisions with external objects. This effectively reduces the risk of damage to the battery film roll 2, ensures its quality, and ultimately improves the pass rate and performance stability of battery products.

[0046] In some examples, the length directions of the first tooth 5 and the second tooth 6 are both parallel to the axis of the battery film roll 2.

[0047] For example, such as Figure 2 As shown, the length directions of the first clamping tooth 5 and the second clamping tooth 6 are both parallel to the axis of the battery film roll 2, making the spatial layout of the clamping structure more reasonable.

[0048] The advantages are that the spatial layout of the clamping structure is optimized, the potential obstruction of the clamping process by the moving frame 3 is avoided, the clamping action is smoother, the stability and reliability of the clamping are improved, and the possibility of damage to the battery film roll 2 during transportation is reduced.

[0049] In some examples, there are several first teeth 5 and several second teeth 6; several second teeth 6 and several first teeth 5 are distributed at intervals; after the second teeth 6 and the first teeth 5 slide close together, the second teeth 6 enter the gap between two adjacent first teeth 5.

[0050] For example, such as Figure 2 As shown, multiple first clamping teeth 5 and second clamping teeth 6 are set and arranged in an alternating pattern.

[0051] Specifically, when the lifting frame 4 slides down and the battery film roll 2 passes through the channel 401, the second clamping tooth 6 and the first clamping tooth 5 are controlled to slide horizontally in opposite directions, so that the second clamping tooth 6 and the first clamping tooth 5 move closer to each other. The second clamping tooth 6 will be embedded in the gap between the adjacent first clamping tooth 5. As the two move closer, the bottom of the battery film roll 2 is gradually clamped, so as to completely support the bottom.

[0052] The advantage is that it increases the contact area with the battery film roll 2, making the clamping force distribution more uniform, avoiding damage to the battery film roll 2 due to excessive local force, improving the reliability and stability of the clamp, and better protecting the quality of the battery film roll 2.

[0053] In some examples, the ends of the second tooth 6 and the first tooth 5 that are close to each other are chamfered.

[0054] For example, such as Figure 3 As shown, the ends of the second tooth 6 and the first tooth 5 that are close to each other are chamfered.

[0055] The advantages are that it improves the smoothness of the clamping process, reduces wear between the clamping teeth, extends the service life of the clamping teeth, reduces the risk of damage to the battery film roll 2 during clamping, and ensures the quality of the battery film roll 2.

[0056] In some examples, the second tooth 6 has a first mounting portion 601 near the end of the first tooth 5, and the first tooth 5 has a second mounting portion 501 near the end of the second tooth 6. It also includes abutting wheels 7, and there are several abutting wheels 7. The several abutting wheels 7 are respectively rotatably disposed on the first mounting portion 601 and the second mounting portion 501.

[0057] For example, such as Figure 3 As shown, by opening mounting holes in the first mounting part 601 and the second mounting part 501, the abutment wheel 7 is mounted on the mounting part using a pin, so that the abutment wheel 7 can rotate around its own axis.

[0058] Specifically, when the second clamping tooth 6 slides towards the first clamping tooth 5 to clamp the battery film roll 2, the abutting wheel 7 contacts the surface of the battery film roll 2. During the clamping process, the abutting wheel 7 rotates with the slight movement of the battery film roll 2, reducing the relative sliding friction between it and the battery film roll 2.

[0059] The advantage is that it further reduces frictional damage to the battery film roll 2 during the clamping process, protects the surface integrity of the battery film roll 2, and improves the safety of transportation.

[0060] In some examples, both the second tooth 6 and the first tooth 5 have an abutting arc surface 602; the abutting arc surface 602 is used to abut against the battery film roll 2.

[0061] For example, such as Figure 3 As shown, the portions of the second clamping tooth 6 and the first clamping tooth 5 that contact the battery film roll 2 are designed as abutting arc surfaces 602. The clamping teeth can be molded or machined to form a suitable abutting arc surface 602 according to the common shape of the battery film roll 2.

[0062] The advantage is that it increases the contact area between the clamping teeth and the battery film roll 2, making the clamping force distribution more uniform, avoiding damage to the battery film roll 2 caused by local pressure concentration, improving the stability and reliability of the clamping, and protecting the quality of the battery film roll 2.

[0063] In some examples, a sliding frame 8 is also included, which is horizontally slidably mounted on the lifting frame 4 and located within the channel 401; a plurality of second clamping teeth 6 and first clamping teeth 5 are respectively horizontally slidably mounted within the channel 401 via two sliding frames 8.

[0064] For example, such as Figure 2As shown, the sliding frame 8 is installed in the channel 401 of the lifting frame 4 via a horizontal guide rail, and multiple second clamping teeth 6 and first clamping teeth 5 are respectively installed on two sliding frames 8. For example, bolts are used to fix the first clamping teeth 5 and the second clamping teeth 6 to the two sliding frames 8 respectively, ensuring that the first clamping teeth 5 and the second clamping teeth 6 can move synchronously with the two sliding frames 8 respectively.

[0065] The advantage is that it ensures that multiple first clamping teeth 5 and second clamping teeth 6 can move synchronously and in coordination, improving the consistency and stability of the clamping action.

[0066] In some examples, a bidirectional lead screw 9 is also included, which is rotatably mounted on the lifting frame 4; a sliding frame 8 is threadedly connected to the bidirectional lead screw 9; and a rotation drive 10 is mounted on the lifting frame 4 to drive the bidirectional lead screw 9 to rotate, so that the sliding frame 8 slides horizontally.

[0067] For example, such as Figure 2 As shown, the bidirectional lead screw 9 is rotatably mounted on the lifting frame 4. The bidirectional lead screw 9 has two sections of threads with the same pitch but opposite directions. Two sliding brackets 8 are respectively connected to the two sections of threads of the bidirectional lead screw 9. The rotation drive component 10 is connected to the bidirectional lead screw 9. For example, a motor can be used as the rotation drive component 10, and the motor shaft can be connected to the bidirectional lead screw 9 through a coupling to realize power transmission.

[0068] Specifically, the rotating drive 10 drives the bidirectional lead screw 9 to rotate. Since the two sliding frames 8 are respectively connected to the bidirectional threaded connection of the bidirectional lead screw 9, the rotation of the bidirectional lead screw 9 is converted into the two sliding frames 8 sliding in opposite directions, thereby driving the second clamping tooth 6 and the first clamping tooth 5 to move closer or further apart, realizing the clamping or releasing operation of the battery film roll 2.

[0069] The advantage is that it can precisely control the moving distance and speed of the first clamping tooth 5 and the second clamping tooth 6, realize the precise adjustment of the clamping force of the battery film roll 2, improve the accuracy and reliability of clamping, and reduce the risk of damage to the battery film roll 2 due to improper operation.

[0070] In some examples, a lifting drive 11 is also included, which is mounted on the movable frame 3 and is used to drive the lifting frame 4 to rise and fall.

[0071] For example, such as Figure 1 As shown, the lifting drive component 11 is connected to the lifting frame 4. For example, a cylinder or electric push rod can be used as the lifting drive component 11, which is connected to the lifting frame 4 through a piston rod to realize the transmission of lifting power.

[0072] Specifically, when it is necessary to lower the lifting frame 4 to approach the battery film roll 2 or raise it to take the battery film roll 2 away from the workstation 1, the operator controls the lifting drive component 11, which drives the lifting frame 4 to rise or fall along the guide rail on the movable frame 3.

[0073] The advantage is that it enables the automatic lifting of the lifting frame 4, improves the convenience and efficiency of operation, precisely controls the position of the lifting frame 4, ensures that the battery film roll 2 can be smoothly clamped and transferred, and reduces manual operation errors and labor intensity.

[0074] In some examples, casters 12 are also included, which are disposed on the lower surface of the movable frame 3; the movable frame 3 moves on the ground via the casters 12.

[0075] For example, such as Figure 1 As shown, casters 12 are installed on the lower surface of the mobile frame 3. For example, polyurethane casters 12 with brakes are selected, and the casters 12 are installed on the four corners of the mobile frame 3 with bolts to ensure that the mobile frame 3 can move flexibly.

[0076] Specifically, the operator pushes the mobile frame 3 and uses the omnidirectional wheels 12 to easily move the device to the workstation 1 to perform the clamping operation of the battery film roll 2, and then moves it to the target position for placement.

[0077] The advantage is that it greatly enhances the mobility and flexibility of the mobile frame 3, enabling the device to move quickly and conveniently between different workstations 1 in the workshop, reducing transfer time losses, improving transfer efficiency, and reducing the labor intensity of operators.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
