Description

Technical Field

[0001] This utility model belongs to the field of battery packing technology, and in particular relates to a blue film buffering mechanism and a packing machine. Background Technology

[0002] In battery production lines, the processing speeds of the blue film unwinding mechanism and the coating mechanism are inconsistent. Directly connecting the blue film unwinding mechanism to the coating mechanism can easily lead to unstable blue film tension and a risk of film breakage. Therefore, a blue film buffer mechanism is needed between the unwinding and coating mechanisms to maintain blue film tension. However, existing blue film buffer mechanisms generally only have roller structures, which are prone to problems such as blue film slippage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a blue film buffering mechanism and a coating machine to address the technical problem that existing blue film buffering mechanisms are prone to blue film slippage.

[0004] To address the aforementioned technical problems, this utility model provides a blue film buffer mechanism, including a buffer mounting frame, a clamping structure, and a blue film traction assembly. The buffer mounting frame is sequentially arranged with an inlet position, a buffer position, and an outlet position along a first direction, through which the blue film can sequentially pass. The clamping structure is mounted on the buffer mounting frame and has a clamping state and a releasing state. In the clamping state, the clamping structure can clamp the blue film at the inlet position and / or the blue film at the outlet position; in the releasing state, the clamping structure can release the clamping of the blue film. The blue film traction assembly is disposed at the buffer position. The blue film traction assembly includes a buffer shaft, a traction frame, a traction shaft, and a traction drive structure. The buffer shaft is rotatably mounted on the buffer mounting frame.

In the second clamping state, the outlet clamping assembly can clamp the blue film at the outlet position. In the second releasing state, the outlet clamping assembly can release the clamping of the blue film, and the blue film can be conveyed to the outside of the blue film buffer mechanism through the outlet clamping assembly. When the inlet clamping assembly is in the first clamping state, and / or when the outlet clamping assembly is in the second clamping state, the clamping structure is in the clamping state; when the inlet clamping assembly is in the first releasing state and the outlet clamping assembly is in the second releasing state, the clamping structure is in the releasing state.

[0007] Optionally, the inlet clamping assembly includes a first rotating shaft and a first pressure plate.

[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1 to 4 As shown, the blue film buffer mechanism 100 provided in this embodiment of the present invention includes a buffer mounting frame 1, a clamping structure, and a blue film traction component 3. The buffer mounting frame 1 is sequentially provided with an inlet position 1a, a buffer position 1b, and an outlet position 1c along a first direction X. The blue film 200 can pass through the inlet position 1a, the buffer position 1b, and the outlet position 1c sequentially. The clamping structure is installed on the buffer mounting frame 1 and has a clamping state and a releasing state. In the clamping state, the clamping structure can clamp the blue film 200 at the inlet position 1a and / or the blue film 200 at the outlet position 1c. In the releasing state, the clamping structure can release the clamping of the blue film. The blue film traction assembly 3 is located at the buffer position 1b. The blue film traction assembly 3 includes a buffer shaft 31, a traction frame 32, a traction shaft 33, and a traction drive structure 34. The buffer shaft 31 is rotatably mounted on the buffer mounting frame 1. The traction drive structure 34 is mounted on the buffer mounting frame 1 and is used to drive the traction frame 32 to move along the second direction Z. The first direction X intersects the second direction Z. The traction shaft 33 is rotatably mounted on the traction frame 32. The blue film 200, located at the buffer position 1b, is wound around the buffer shaft 31 and the traction shaft 33.

[0023] For example, the traction drive structure 34 may adopt a drive structure of motor and lead screw to achieve stable drive of traction frame 32.

[0024] The blue film buffer mechanism 100 provided in this embodiment of the utility model can first adjust the clamping structure to the released state when it is necessary to buffer the blue film 200, so that the blue film 200 can pass through the inlet position 1a, the buffer position 1b and the outlet position 1c in sequence, and be buffered by the blue film traction component 3. During the buffering process, the traction drive structure 34 can drive the traction frame 32 to move along the second direction Z to adjust the distance between the buffer shaft 31 and the traction shaft 33 on the traction frame 32, thereby adjusting the buffering amount (i.e., the length of the buffered blue film 200). For example, the greater the distance between the buffer shaft 31 and the traction shaft 33 on the traction frame 32, the greater the buffering amount. The smaller the distance between the buffer shaft 31 and the traction shaft 33 on the traction frame 32, the smaller the buffering amount. When the buffering amount reaches the preset value, the clamping structure is adjusted to the clamping state, thereby fixing the blue film 200 in the blue film buffer mechanism 100 and stabilizing the tension of the blue film 200 to reduce the risk of the blue film 200 slipping.

[0025] In one embodiment, such as Figures 1 to 4 As shown, the clamping structure includes an inlet clamping assembly 2 and an outlet clamping assembly 4. The inlet clamping assembly 2 is located at the inlet position 1a and has a first clamping state and a first releasing state. In the first clamping state, the inlet clamping assembly 2 can clamp the blue film 200 at the inlet position 1a. In the first releasing state, the inlet clamping assembly 2 can release the clamping of the blue film 200, and the blue film 200 can be conveyed to the buffer position 1b via the inlet clamping assembly 2.

[0026] The outlet clamping assembly 4 is located at the outlet position 1c. The outlet clamping assembly 4 has a second clamping state and a second releasing state. In the second clamping state, the outlet clamping assembly 4 can clamp the blue film 200 at the outlet position 1c. In the second releasing state, the outlet clamping assembly 4 can release the clamping of the blue film 200, and the blue film 200 can be conveyed to the outside of the blue film buffer mechanism 100 via the outlet clamping assembly 4.

[0027] When the inlet clamping assembly 2 is in the first clamping state and / or the outlet clamping assembly 4 is in the second clamping state, the clamping structure is in a clamping state. When the inlet clamping assembly 2 is in the first loosening state and the outlet clamping assembly 4 is in the second loosening state, the clamping structure is in a released state.

[0028] For example, "the inlet clamping component 2 is in a first clamping state, and / or the outlet clamping component 4 is in a second clamping state" means: the inlet clamping component 2 is in a first clamping state; or the outlet clamping component 4 is in a second clamping state; or the inlet clamping component 2 is in a first clamping state and the outlet clamping component 4 is in a second clamping state.

[0029] When buffering of the blue membrane 200 is required, the outlet clamping component 4 at the outlet position 1c can be adjusted to the second clamping state to fix the head end of the blue membrane 200. At the same time, the inlet clamping component 2 at the inlet position 1a can be adjusted to the first loosening state, allowing the blue membrane 200 to be conveyed to the buffering position 1b and buffered by the blue membrane traction component 3. When the buffering amount reaches the preset value, the inlet clamping component 2 at the inlet position 1a can be adjusted to the first clamping state.

[0030] When applying the battery film, the outlet clamping component 4 at the outlet position 1c can be adjusted to the second loose state first. Then, the traction drive structure 34 drives the traction frame 32 to move along the second direction Z, so that the distance between the buffer shaft 31 and the traction shaft 33 on the traction frame 32 gradually decreases, so as to release the blue film 200. After the buffer amount has been conveyed by the outlet clamping component 4 to the outside of the blue film buffer mechanism 100, the inlet clamping component 2 at the inlet position 1a can be adjusted to the first loose state, so that the blue film 200 is sent out sequentially through the inlet clamping component 2 at the inlet position 1a, the blue film traction component 3 at the buffer position 1b and the outlet clamping component 4 at the outlet position 1c.

[0031] It should be noted that this is only one of the working processes of the blue film buffer mechanism 100 when applying battery film. In actual applications, when only a portion of the buffer amount is transported outside the blue film buffer mechanism 100 by the outlet pressing component 4, the inlet pressing component 2 at the inlet position 1a can be adjusted to the first loose state. However, the driving of the traction drive structure 34 on the traction frame 32 must be stopped to maintain the tension of the blue film 200.

[0032] In one embodiment, such as Figures 1 to 4 As shown, the cache mounting bracket 1 includes a first mounting plate 11 and a second mounting plate 12, which are spaced apart along a third direction Y. The first direction X and the second direction Z are perpendicular to each other along the third direction Y. For example, the second direction Z is the height direction.

[0033] The inlet clamping assembly 2, the blue film traction assembly 3, and the outlet clamping assembly 4 are all installed between the first mounting plate 11 and the second mounting plate 12.

[0034] In one embodiment, such as Figures 1 to 4 As shown, the cache mounting bracket 1 may also include a connecting plate 13, which is connected between the first mounting plate 11 and the second mounting plate 12 to enhance the stability of the cache mounting bracket.

[0035] In one embodiment, such as Figure 2 and Figure 4As shown, the inlet clamping assembly 2 includes a first rotating shaft 21 and a first pressure plate 22. The first rotating shaft 21 is rotatably mounted on the buffer mounting frame 1, and the blue membrane 200 at the inlet position 1a is wound around the first rotating shaft 21. The first pressure plate 22 is movably mounted on the buffer mounting frame 1 along the second direction Z, and the first pressure plate 22 can move closer to or further away from the first rotating shaft 21 when it moves along the second direction Z.

[0036] In the first clamping state, the first pressure plate 22 is close to the first rotating shaft 21 and can cooperate with the first rotating shaft 21 to clamp the blue film 200 on the first rotating shaft 21. In the first releasing state, the first pressure plate 22 is away from the first rotating shaft 21.

[0037] By adjusting the distance between the first pressure plate 22 and the first rotating shaft 21 along the second direction Z, the clamping or unclamping of the blue film 200 can be achieved.

[0038] In one embodiment, such as Figure 2 and Figure 4 As shown, the inlet clamping assembly 2 also includes a first clamping driver 23, which is mounted on the buffer mounting bracket 1. The output end of the first clamping driver 23 is connected to the first pressure plate 22, and the first clamping driver 23 is used to drive the first pressure plate 22 to move along the second direction Z.

[0039] For example, the first clamping driver 23 may be a first linear drive cylinder, or it may be a first linear motor.

[0040] The first pressure plate 22 is driven to move along the second direction Z by the first pressure driver 23, so that the first pressure plate 22 can move closer to or away from the first rotating shaft 21 along the second direction Z.

[0041] In one embodiment, such as Figure 2 and Figure 4 As shown, the inlet clamping assembly 2 also includes a first pressure plate mounting bracket 24, which is slidably connected to the buffer mounting bracket 1 along the second direction Z. The output end of the first clamping driver 23 is connected to the first pressure plate mounting bracket 24, and the first clamping driver 23 is used to drive the first pressure plate mounting bracket 24 to move along the second direction Z. The first pressure plate 22 is connected to the first pressure plate mounting bracket 24.

[0042] For example, in order to make the movement of the first pressure plate mounting bracket 24 more stable, a first slide rail structure 25 can be provided. The first slide rail structure 25 is installed between the first pressure plate mounting bracket 24 and the buffer mounting bracket 1, and the sliding guide of the first pressure plate mounting bracket 24 is realized through the first slide rail structure 25.

[0043] The first clamping driver 23 drives the first pressure plate mounting bracket 24 to move along the second direction Z, thereby causing the first pressure plate 22 connected to the first pressure plate mounting bracket 24 to move along the second direction Z.

[0044] In one embodiment, such as Figure 2 and Figure 4 As shown, the blue film traction assembly 3 also includes a traction fixing seat 35, which is mounted on the buffer mounting frame 1. The traction drive structure 34 is mounted on the traction fixing seat 35, so that the traction drive structure 34 can be indirectly mounted on the buffer mounting frame 1 through the traction fixing seat 35.

[0045] In one embodiment, such as Figures 1 to 4 As shown, the traction frame 32 is slidably connected to the traction fixing seat 35 along the second direction Z.

[0046] For example, in order to make the movement of the traction frame 32 more stable, a traction slide rail structure 36 can be provided. The traction slide rail structure 36 is installed between the traction frame 32 and the traction fixed seat 35, and the sliding guide of the traction frame 32 is realized through the traction slide rail structure 36.

[0047] In one embodiment, such as Figure 4 As shown, multiple buffer shafts 31 are provided, and the multiple buffer shafts 31 are spaced apart along the first direction X. Along the first direction X, at least one traction shaft 33 is provided between every two adjacent buffer shafts 31, and each traction shaft 33 is rotatably mounted on the traction frame 32.

[0048] For example, such as Figure 4 In the illustrated embodiment, three buffer axes 31 are provided, and two traction axes 33 are provided. For easy distinction, the three buffer axes 31 can be labeled as the first buffer axis 31a, the second buffer axis 31b, and the third buffer axis 31c, respectively, and the two traction axes 33 can be labeled as the first traction axis 33a and the second traction axis 33b, respectively. The first traction axis 33a is located between the first buffer axis 31a and the second buffer axis 31b, and the second traction axis 33b is located between the second buffer axis 31b and the third buffer axis 31c.

[0049] By setting multiple buffer axes 31 and ensuring that at least one traction axis 33 is provided between every two adjacent buffer axes 31, the buffer capacity of the blue film 200 can be increased. Specifically, the more buffer axes 31 and traction axes 33 there are, the larger the buffer capacity; the fewer buffer axes 31 and traction axes 33 there are, the smaller the buffer capacity.

[0050] In one embodiment, such as Figure 1 and Figure 4 As shown, the outlet clamping assembly 4 includes a second rotating shaft 41 and a second pressure plate 42. The second rotating shaft 41 is rotatably mounted on the buffer mounting frame 1, and the blue membrane 200 at the outlet position 1c is wound around the second rotating shaft 41. The second pressure plate 42 is movably mounted on the buffer mounting frame 1 along the second direction Z, and the second pressure plate 42 can move closer to or further away from the second rotating shaft 41 when moving along the second direction Z.

[0051] In the second clamping state, the second pressure plate 42 is close to the second rotating shaft 41 and can cooperate with the second rotating shaft 41 to clamp the blue film 200 on the second rotating shaft 41. In the second releasing state, the second pressure plate 42 is away from the second rotating shaft 41.

[0052] By adjusting the distance between the second pressure plate 42 and the second rotating shaft 41 along the second direction Z, the clamping or unclamping of the blue film 200 can be achieved.

[0053] In one embodiment, such as Figure 1 and Figure 4 As shown, the outlet clamping assembly 4 also includes a second clamping driver 43, which is mounted on the buffer mounting bracket 1. The output end of the second clamping driver 43 is connected to the second pressure plate 42, and the second clamping driver 43 is used to drive the second pressure plate 42 to move along the second direction Z.

[0054] For example, the second clamping actuator 43 may be a second linear drive cylinder, or it may be a second linear motor.

[0055] The second pressure plate 42 is driven to move along the second direction Z by the second pressure driver 43, so that the second pressure plate 42 can move closer to or away from the second rotating shaft 41 along the second direction Z.

[0056] In one embodiment, such as Figure 1 and Figure 4 As shown, the outlet clamping assembly 4 also includes an adjusting plate 44, which is slidably connected to the buffer mounting bracket 1 along the first direction X. The second rotating shaft 41 is rotatably mounted on the adjusting plate 44. The second pressure plate 42 is movably mounted on the adjusting plate 44 along the second direction Z. The second clamping driver 43 is mounted on the adjusting plate 44.

[0057] For example, in order to make the movement of the adjustment plate 44 more stable, an adjustment slide rail structure 47 can be provided. The adjustment slide rail structure 47 is installed between the adjustment plate 44 and the buffer mounting bracket 1, and the sliding guide of the adjustment plate 44 is realized by adjusting the slide rail structure 47.

[0058] By sliding the adjustment plate 44 along the first direction X to the buffer mounting bracket 1, the positions of the second pressure plate 42 and the second rotating shaft 41 can be adjusted in the first direction X to adapt to different working conditions.

[0059] In one embodiment, such as Figure 1 and Figure 4As shown, the outlet clamping assembly 4 also includes a second pressure plate mounting bracket 45, which is slidably connected to the adjusting plate 44 along the second direction Z. The output end of the second clamping driver 43 is connected to the second pressure plate mounting bracket 45, and the second clamping driver 43 is used to drive the second pressure plate mounting bracket 45 to move along the second direction Z. The second pressure plate 42 is connected to the second pressure plate mounting bracket 45.

[0060] For example, in order to make the movement of the second pressure plate mounting bracket 45 more stable, a second slide rail structure 46 can be provided. The second slide rail structure 46 is installed between the second pressure plate mounting bracket 45 and the adjusting plate 44, and the sliding guide of the second pressure plate mounting bracket 45 is realized through the second slide rail structure 46.

[0061] The second clamping driver 43 drives the second pressure plate mounting bracket 45 to move along the second direction Z, thereby causing the second pressure plate 42 connected to the second pressure plate mounting bracket 45 to move along the second direction Z.

[0062] In one embodiment, such as Figures 1 to 4 As shown, the blue film buffer mechanism 100 also includes an electrostatic elimination component 5, which is used to eliminate static electricity on the blue film 200 on the blue film buffer mechanism 100 to avoid electrostatic interference.

[0063] In one embodiment, such as Figures 1 to 4 As shown, the static elimination component 5 includes a first static eliminator 51 and a second static eliminator 52. The first static eliminator 51 is disposed at the inlet position 1a. The first static eliminator 51 is used to eliminate static electricity on the blue film 200 at the inlet position 1a, so as to eliminate the static electricity of the blue film 200 entering the inlet position 1a.

[0064] The static elimination component 5 includes a second static eliminator 52, which is disposed at the outlet position 1c. The second static eliminator 52 is used to eliminate static electricity from the blue film 200 at the outlet position 1c, so as to eliminate the static electricity of the blue film 200 sent out through the outlet position 1c.

[0065] In one embodiment, such as Figures 1 to 4 As shown, the connecting plate 13 is located at the inlet position 1a, and the first static eliminator 51 is installed on the connecting plate 13 to realize the installation of the first static eliminator 51.

[0066] The second static eliminator 52 is installed between the first mounting plate 11 and the second mounting plate 12 to realize the installation of the second static eliminator 52.

[0067] In other embodiments not shown in the figure, only a first static eliminator or only a second static eliminator may be provided, which can be adjusted according to actual needs.

[0068] This utility model embodiment also provides a coating machine, which includes the above-mentioned blue film buffer mechanism 100.

[0069] The coating machine provided in this embodiment of the utility model has a blue film buffer mechanism 100. When buffering the blue film 200 is required, the clamping structure can be adjusted to the released state, allowing the blue film 200 to pass through the inlet position 1a, buffer position 1b, and outlet position 1c in sequence, and be buffered by the blue film traction component 3. During the buffering process, the traction drive structure 34 can drive the traction frame 32 to move along the second direction Z, thereby adjusting the distance between the buffer shaft 31 and the traction shaft 33 on the traction frame 32, thus adjusting the buffer amount (i.e., the length of the buffered blue film 200). When the buffer amount reaches the preset value, the clamping structure is adjusted to the clamping state, thereby fixing the blue film 200 in the blue film buffer mechanism 100 and stabilizing the tension of the blue film 200 to reduce the risk of the blue film 200 slipping.

[0070] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
