Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment, specifically a cutting module, a film strip cutting mechanism, and a film strip processing device. Background Technology

[0002] In the production of battery strings, membrane strips are required. Currently, a cutting assembly is generally used to cut the membrane sheets into strips. Existing cutting assemblies typically include a mounting base and multiple blades arranged side by side on it. To control the blade spacing (i.e., blade pitch), spacers are usually placed between the blades to maintain a certain spacing accuracy. However, due to manufacturing tolerances, the spacers themselves have certain dimensional errors. During actual assembly, the errors of multiple spacers gradually accumulate. Especially when the number of blades is large (e.g., 35 blades), the cumulative effect of errors is significant, leading to an increase in the overall blade pitch deviation. This reduces the cutting accuracy and consistency of the membrane strips, adversely affecting the final product quality of the battery strings. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a cutting assembly, the detailed technical solution of which is as follows:

[0004] A cutting tool assembly includes a mounting base, n blades, n clamping blocks, and a fixing member, wherein:

[0005] The mounting base is provided with n mounting slots spaced apart along a first direction. Each mounting slot extends along a second direction. Each mounting slot includes a vertical mounting surface and an inclined mounting surface arranged opposite each other along the first direction. The distance between the vertical mounting surface and the inclined mounting surface gradually decreases along the direction toward the bottom of the mounting base. The second direction is perpendicular to the first direction.

[0006] Each mounting slot is provided with a blade and a clamping block. The first side surface of the blade is in contact with the vertical mounting surface. The clamping block includes a vertical clamping surface and an inclined clamping surface arranged opposite each other along a first direction. The vertical clamping surface is in contact with the second side surface of the blade, and the inclined clamping surface is clamped to the inclined mounting surface.

[0007] The fasteners are fixedly installed on the mounting base to press each clamping block into its corresponding mounting groove;

[0008] n≥2.

[0009] This application achieves individual positioning and locking of each blade by independently setting a mounting groove for each blade on the mounting base, and setting the mounting groove as a wedge-shaped groove composed of a vertical mounting surface and an inclined mounting surface. A clamping block is used to cooperate with this groove, utilizing the inclined surface for clamping, thus achieving individual positioning and locking of each blade. By setting a fixing component, the clamping block is pressed and limited into the corresponding mounting groove, preventing the clamping block from loosening during blade operation. The mounting grooves on the mounting base can be machined in one piece with high precision, eliminating the error accumulation problem caused by traditional spacers, improving the accuracy of blade spacing, and ultimately enhancing the cutting consistency of the film strip.

[0010] In some embodiments, the mounting base includes a body, a first support bar, and a second support bar, wherein: the middle portion of the body has an upwardly protruding mounting portion extending along a first direction, and a mounting groove is formed on the mounting portion; the first support bar and the second support bar are fixedly connected to the body and located on both sides of the mounting portion along a second direction, and both the first support bar and the second support bar extend along the first direction; the two side edges of the fastener along the second direction are respectively supported and fixed on the first support bar and the second support bar.

[0011] The mounting base is designed as a split structure consisting of a main body, a first support bar, and a second support bar, which facilitates the machining and shaping of the mounting groove. Furthermore, the first and second support bars can be easily replaced after prolonged use and deformation, ensuring stable support for the fasteners.

[0012] In some embodiments, the fastener includes a fixing plate and n sets of clamping screws, wherein: the fixing plate is fixedly connected to the mounting base; the n sets of clamping screws are screwed onto the fixing plate at intervals along a first direction and correspond one-to-one with the clamping blocks, each set of clamping screws includes at least two clamping screws spaced apart along a second direction, and each set of clamping screws is used to clamp the corresponding clamping block; or, the fastener includes a fixing plate, the two ends of which are connected to the mounting base by fasteners, and the fixing plate is used to press down on each clamping block.

[0013] By using n sets of clamping screws on the fixing plate, each clamping block is independently clamped and fixed, ensuring that each clamping block can be pressed and held in its corresponding mounting slot. Using the fixing plate to clamp the blocks simplifies the structure of this application.

[0014] In some embodiments, the fixing plate is an integral structure, and the fixing plate is provided with n first clearance grooves corresponding one-to-one with the blades, and each blade passes through the corresponding first clearance groove.

[0015] The use of a single, integrated fixing plate to uniformly clamp all clamping blocks further simplifies the structure of this application.

[0016] In some embodiments, the fixing plate is composed of at least two unit plates arranged side by side along a first direction, and each unit plate is fixedly connected to the mounting base; each unit plate is provided with at least one second clearance groove, and there is a clearance gap between two adjacent unit plates; each second clearance groove and each clearance gap is provided with a corresponding blade.

[0017] Multiple unit plates are used to clamp n clamping blocks. When a blade needs to be replaced, only the corresponding unit plate needs to be disassembled and reassembled.

[0018] In some embodiments, each clamping block has a limiting block protruding from the vertical clamping surface on its vertical clamping surface, and the blade has a limiting hole that mates with the limiting block. The limiting block is used to be inserted into the limiting hole. The mounting base has a clearance channel for avoiding the limiting block at the location corresponding to each mounting groove.

[0019] Ensure the blade is contained between the clamping block and the vertical mounting surface of the mounting slot. This prevents the blade from falling out between the clamping block and the vertical mounting surface of the mounting slot even if the clamping block becomes loose.

[0020] In some embodiments, the mounting base is provided with n extension slots that correspond one-to-one with the mounting slots and pass through each other. The extension slots have vertical extension surfaces that are coplanar with the vertical mounting surfaces of the corresponding mounting slots.

[0021] By setting an extension groove located below the mounting groove and communicating with the mounting groove, the blade can be inserted into the mounting base to a deeper depth, thereby improving the installation stability of the blade.

[0022] In some embodiments, the extension slots extend through the mounting base, and the cutter assembly further includes a limiting plate disposed at the bottom of the mounting base, the limiting plate blocking the openings of each extension slot.

[0023] The limiting plate limits the blade and prevents it from passing through the extension slot and exiting the mounting base.

[0024] This application also provides a membrane strip cutting mechanism, which includes a drive unit and a cutter assembly as described in any of the above claims. The cutter assembly is connected to the drive unit for transmission. The drive unit is used to drive the cutter assembly to rise and fall and to translate along a second direction, so as to drive each blade to cut the membrane into membrane strips.

[0025] The membrane strip cutting mechanism provided in this application improves the consistency of membrane strip cutting due to the high precision of the blade spacing of the cutting assembly.

[0026] This application also provides a membrane strip processing device, including the above-mentioned membrane strip cutting mechanism and carrier, wherein: the carrier is used to support the membrane sheet to be cut; the membrane strip cutting mechanism is located above the carrier during use and is used to cut the membrane sheet located on the carrier into membrane strips.

[0027] Through the cooperation of the platform and the membrane strip cutting mechanism, the membrane strip processing device of this application realizes the bearing and cutting of the membrane sheet and improves the cutting consistency of the membrane strip. Attached Figure Description

[0047] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0048] In this specification, for ease of description and consistent understanding, the relative positional relationships of the components will be defined with reference to the directions shown in the accompanying drawings. For example, the use of directional terms such as "upper," "lower," "top," and "bottom" is generally based on the layout of the drawings. It should be understood that these directional terms are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In particular, in the actual application scenarios of the cutting blade assembly of this application, it may be installed and used in any spatial orientation, such as inverted installation (i.e., blade facing down). All directional descriptions in this specification should be understood as defining the structural relationships of the assembly itself, and should not be limited to a specific usage orientation.

[0049] As described in the background section, existing cutting assemblies typically use spacers between the blades to maintain a certain spacing accuracy in order to control the blade spacing (i.e., blade pitch). However, due to manufacturing tolerances, the spacers themselves have dimensional errors, which accumulate gradually during actual assembly. This cumulative error effect is particularly pronounced when the number of blades is large (e.g., 35 blades), leading to an overall increase in blade pitch deviation. This reduces the cutting accuracy and consistency of the membrane strips, negatively impacting the final battery string product quality.

[0050] In view of this, this application provides a cutting assembly that can eliminate the error accumulation problem caused by traditional spacers, improve the accuracy of blade spacing, and ultimately improve the cutting consistency of the membrane strip.

[0051] Figures 1 to 5 The structure of the cutter assembly in one embodiment of this application is shown. Figures 6 to 10 The structure of a cutter assembly in another embodiment of this application is shown.

[0052] like Figures 1 to 10 As shown, the cutter assembly provided in this application includes a mounting base 1, n blades 2, n clamping blocks 3, and a fixing member 4. Wherein, n ≥ 2, meaning the cutter assembly includes at least two blades.

[0053] The mounting base 1 has n mounting slots 16 spaced apart along a first direction (e.g., the X direction), and each mounting slot 16 extends along a second direction (e.g., the Y direction), which is perpendicular to the first direction. Each mounting slot 16 includes a vertical mounting surface and an inclined mounting surface arranged opposite each other along the first direction, and the distance between the vertical mounting surface and the inclined mounting surface gradually decreases along the direction toward the bottom of the mounting base 1.

[0054] Each mounting slot 16 is provided with a blade 2 and a clamping block 3, wherein the first side surface of the blade 2 is in contact with the vertical mounting surface. The clamping block 3 includes a vertical clamping surface and an inclined clamping surface arranged opposite each other along a first direction, wherein the vertical clamping surface is in contact with the second side surface of the blade 2, and the inclined clamping surface is clamped to the inclined mounting surface.

[0055] The fastener 4 is fixedly installed on the mounting base 1 and is used to press each clamping block 3 into the corresponding mounting groove 16.

[0056] The cutting blade assembly of this application achieves individual positioning and locking of each blade 2 by independently setting a mounting groove 16 for each blade 2 on the mounting base 1, and setting the mounting groove 16 as a wedge-shaped groove composed of a vertical mounting surface and an inclined mounting surface, and using a clamping block 3 that cooperates with it to clamp the blade 2 by means of inclined surface cooperation.

[0057] By setting the fixing component 4, the clamping block 3 is pressed and limited into the corresponding mounting groove 16, preventing the clamping block 3 from loosening during the operation of the blade 2. The mounting groove 16 on the mounting base 1 can be machined in one piece with high machining precision, eliminating the error accumulation problem caused by traditional spacer blocks, improving the accuracy of the blade 2 spacing, and ultimately improving the cutting consistency of the film strip.

[0058] like Figure 1 and Figure 5 As shown, in some embodiments, the mounting base 1 includes a body 11, a first support bar 12, and a second support bar 13, wherein: the middle portion of the body 11 has an upwardly protruding mounting portion 17 extending along a first direction, and a mounting groove 16 is formed on the mounting portion 17. The first support bar 12 and the second support bar 13 are fixedly connected to the body 11 and located on both sides of the mounting portion 17 along a second direction, and both the first support bar 12 and the second support bar 13 extend along the first direction.

[0059] The two sides of the fastener 4 along the second direction are respectively supported and fixed on the first support bar 12 and the second support bar 13.

[0060] The mounting base 1 is designed as a split structure consisting of the main body 11, the first support bar 12, and the second support bar 13, which facilitates the processing and forming of the mounting groove 16. In addition, the first support bar 12 and the second support bar 13 can be easily replaced after deformation due to long-term use, so as to ensure stable support for the fixing member 4.

[0061] Figures 1 to 5 In the illustrated embodiment, the fixing member 4 includes a fixing plate 41 and n sets of clamping screws 42, wherein: the fixing plate 41 is fixedly connected to the mounting base 1. The n sets of clamping screws 42 are screwed onto the fixing plate 41 at intervals along a first direction and correspond one-to-one with the clamping blocks 3. Each set of clamping screws 42 includes at least two clamping screws 42 spaced apart along a second direction, and each set of clamping screws 42 is used to clamp the corresponding clamping block 3.

[0062] By setting n sets of clamping screws 42 on the fixed plate 41 to independently clamp and fix each clamping block 3, it is ensured that each clamping block 3 can be effectively clamped by the corresponding clamping screw 42, thereby keeping it in the corresponding mounting groove 16.

[0063] like Figure 2 As shown, the fixing plate 41 is provided with two screw mounting holes 43 at the positions corresponding to each clamping block 3, that is, each group of clamping screws 42 includes two screws, and the two clamping screws 42 are screwed onto the fixing plate 41 through one screw mounting hole 43, with the end of the clamping screw 42 pressing against the corresponding clamping block 3. The clamping force can be adjusted by turning the clamping screws 42. Of course, in other embodiments, each group of clamping screws 42 can also be set to include three, four, or other numbers of clamping screws 42.

[0064] In some embodiments, bolt mounting holes 44 are provided at both ends of the fixing plate 41, and the fixing plate 41 is screwed onto the mounting base 1 by fixing bolts 5 passing through the bolt mounting holes 44.

[0065] Figures 6 to 10 In the illustrated embodiment, the fixing member 4 only includes a fixing plate 41. The two ends of the fixing plate 41 are connected to the mounting base 1 by fasteners. The fixing plate 41 is used to press down on each clamping block 3. That is, after the two ends of the fixing plate 41 are connected to the mounting base 1 by fasteners, the fixing plate 41 abuts against all the clamping blocks 3 on the surface of the mounting base 1, thereby pressing down on all the clamping blocks 3.

[0066] Similarly, the fastener can be a fixing bolt 5, and bolt mounting holes 44 are provided at corresponding positions at both ends of the fixing plate 41. The fixing bolt 5 passes through the bolt mounting holes 44 and is screwed and fixed on the mounting base 1.

[0067] like Figure 2 and Figure 7 As shown, in some embodiments, the fixing plate 41 is composed of at least two unit plates 411 arranged side by side along a first direction, and each unit plate 411 is fixedly connected to the mounting base 1. Each unit plate 411 is provided with at least one second clearance groove 412, and there is a clearance gap 413 between two adjacent unit plates 411. Each second clearance groove 412 and each clearance gap 413 is provided with a corresponding blade 2.

[0068] Multiple unit plates 411 are used to press n clamping blocks 3. When a certain blade 2 needs to be replaced, only the corresponding unit plate 411 needs to be disassembled and installed. There is no need to disassemble and install other unit plates 411, thereby reducing the workload.

[0069] In some embodiments, n unit plates 411 corresponding one-to-one with the clamping block 3 can be provided, that is, each clamping block 3 is independently clamped by a unit plate 411.

[0070] Of course, in other embodiments, the fixing plate 41 can also be a one-piece structure, with n first clearance grooves corresponding one-to-one with the blades 2 on the fixing plate 41, and each blade 2 protruding from the corresponding first clearance groove. Using a single one-piece fixing plate 41 to uniformly press all the clamping blocks 3 makes the structure of the cutting assembly of this application simpler and more compact.

[0071] like Figures 8 to 10 As shown, in some embodiments, each clamping block 3 has a limiting block 31 protruding from the vertical clamping surface, and the blade 2 has a limiting hole 21 that mates with the limiting block 31. The limiting block 31 is used to be inserted into the limiting hole 21. The mounting base 1 has a clearance channel 14 for avoiding the limiting block 31 at the corresponding position of each mounting groove 16.

[0072] By providing a limiting block 31 on the vertical clamping surface of the clamping block 3, it can be ensured that the blade 2 can be limited between the clamping block 3 and the vertical mounting surface of the mounting groove 16. In this way, even if the clamping block 3 becomes loose, the blade 2 will not fall out from between the clamping block 3 and the vertical mounting surface of the mounting groove 16.

[0073] By providing clearance channels 14 at the locations of the mounting base 1 corresponding to each mounting slot 16, clearance of the limiting block 31 is achieved, thereby allowing the clamping block 3 to smoothly enter and exit the mounting slot 16.

[0074] like Figure 8As shown, in some embodiments, the mounting base 1 is provided with n extension slots 15 that correspond one-to-one with the mounting slots 16 and pass through each other. The extension slots 15 have vertical extension surfaces, and the vertical extension surfaces are coplanar with the vertical mounting surfaces of the corresponding mounting slots 16.

[0075] By providing an extension groove 15 located below and communicating with the mounting groove 16, the blade 2 can be inserted deeper into the mounting base 1, thereby improving the installation stability of the blade 2.

[0076] like Figure 8 As shown, in some embodiments, the extension groove 15 penetrates the mounting base 1. The cutting blade assembly of this application also includes a limiting plate 6 disposed at the bottom of the mounting base 1. The limiting plate 6 is used to block the openings of each extension groove 15, thereby limiting the blade 2 and preventing the blade 2 from passing through the extension groove 15 and exiting the mounting base 1.

[0077] This application also provides a membrane strip cutting mechanism, such as... Figure 11 As shown, the film strip cutting mechanism of this application includes a drive unit 20 and a cutter assembly 10 provided in any of the above embodiments.

[0078] The cutter assembly 10 is connected to the drive unit 20 for transmission. The drive unit 20 is used to drive the cutter assembly 10 to rise and fall and to translate along the second direction, so as to drive each blade 2 of the cutter assembly 10 to cut the film into film strips.

[0079] The membrane strip cutting mechanism provided in this application improves the consistency of membrane strip cutting due to the high precision of the blade spacing of the cutting assembly 10.

[0080] The drive unit 20 can adopt any existing drive structure that can drive the cutter assembly 10 to move. In some embodiments, the drive unit 20 includes a lifting module 201 and a translation module 202, wherein the lifting module 201 is connected to the movable part of the translation module 202, the cutter assembly 10 is connected to the movable part of the lifting module 201, the lifting module 201 is used to drive the cutter assembly 10 to move up and down, and the translation module 202 is used to drive the cutter assembly 10 to translate along the second direction.

[0081] Continue to refer to Figure 11 As shown, this application also provides a membrane strip processing apparatus, including the aforementioned membrane strip cutting mechanism and a platform 30, wherein: the platform 30 is used to support the membrane sheet to be cut. During use, the membrane strip cutting mechanism is located above the platform 30 and is used to cut the membrane sheet located on the platform 30 into membrane strips.

[0082] Through the cooperation of the stage 30 and the membrane strip cutting mechanism, the membrane strip processing device of this application realizes the carrying and cutting of the membrane sheet.

[0083] The stage 30 can adopt any existing stage structure that can support the diaphragm. For example, the stage 30 is provided with adsorption holes, which can adsorb the diaphragm onto the bearing surface of the stage 30. The bearing surface of the stage is also provided with clearance grooves for avoiding the blades in the cutting assembly. The blades slide along the clearance grooves to cut the diaphragm into strips.

[0084] This application provides a sufficiently detailed and specific description. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within its protection scope. The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments. Without contradiction, some optional components in one embodiment can also be used in another embodiment, and some preferred structures of the same component in one embodiment are also applicable to another embodiment. Furthermore, there may be slight differences in the wording of the names of certain components in different embodiments; these slight differences will not affect the understanding of the technical solution of the present invention by those skilled in the art.
