Description

Technical Field

[0001] This application relates to the field of composite membrane manufacturing technology, and in particular to a composite membrane preparation device. Background Technology

[0002] With the increasing demand for composite film products, the manual positioning, assembly, transfer, and cutting methods are gradually becoming inefficient and yield inconsistent results, failing to meet supply demands. Therefore, some semi-automatic transfer equipment has emerged, using manual feeding and pressure rollers to transfer the conductive fabric and release film. While this method improves transfer efficiency, it cannot guarantee the stable position of the conductive fabric, easily leading to problems such as skewing and misalignment during the transfer process. Furthermore, the die-cutting stage still relies on workers to feed the film to the die-cutting blade and manually calibrate the relative position of the film and the blade, resulting in persistent issues of low efficiency and inconsistent yield. Summary of the Invention

[0003] The purpose of this application is to overcome the shortcomings of the existing technology and provide a composite membrane preparation device.

[0004] To achieve the above technical objectives, this application provides a composite film preparation device, comprising: a transfer device for bonding a conductive fabric and a release film to obtain a composite film; and a die-cutting device located downstream of the transfer device for cutting the composite film; wherein the transfer device includes: a first pressure roller group, comprising a first roller and a second roller arranged vertically side-by-side, the conductive fabric and the release film passing between the first roller and the second roller, the first pressure roller group being capable of performing a first pressing on the conductive fabric and the release film; and a second pressure roller group located downstream of the first pressure roller group, comprising a third roller and a fourth roller arranged vertically side-by-side, the conductive fabric and the release film passing between the third roller and the fourth roller. The second pressure roller group passes between the first and fourth rollers, and can perform a second pressing of the conductive cloth and release film.

The second positioning fixture is located downstream of the second pressure roller group and is used to guide the conductive cloth out of the transfer device along a preset path. Among them, the third and fourth rollers are active rollers. During the transfer process, the third and fourth rollers rotate synchronously and in opposite directions, which can pull the conductive cloth and release film downstream. Since the position of the conductive cloth is limited by the first and second positioning fixtures, the composite film obtained by the transfer device can have a uniform and stable configuration.

[0005] The die-cutting device includes: a cutting mechanism, located downstream of the second positioning fixture, for cutting the composite film to obtain a film sheet; a punching mechanism, located downstream of the cutting mechanism, for shaping the film sheet to obtain a finished film of the required size and shape; and a die-cutting positioning fixture for receiving the shaped film sheet. The die-cutting positioning fixture is equipped with a limiting component, which is correspondingly set with the conductive cloth on the film sheet and can calibrate the position and state of the film sheet by limiting the conductive cloth.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] First, refer to Figure 1 The figure shows a finished composite film, which is composed of conductive cloth 1 and release film 2 bonded together. Multiple conductive cloths 1 are arranged side by side on the release film 2. Among them, any one of the conductive cloths 1 extends along a first horizontal direction, and the multiple conductive cloths 1 are spaced apart along a second horizontal direction.

[0028] Continue to refer to Figure 1 Along the second horizontal direction, a row of positioning holes 3 is opened on both sides of the finished composite film. Each row includes two positioning holes 3, and the two positioning holes 3 in a row are spaced apart along the first horizontal direction.

[0029] To prepare a finished composite film, this application provides a composite film preparation device, including: a transfer device 100 for bonding a conductive cloth 1 and a release film 2 to obtain a composite film; and a die-cutting device 200, located downstream of the transfer device 100, for cutting the composite film.

[0030] For details, please refer to Figure 2 In the illustrated embodiment, the transfer device 100 and the die-cutting device 200 are arranged sequentially in the left-right direction. The conductive cloth 1 and the release film 2 are carried from right to left and enter the transfer device 100. The transfer device 100 bonds the two together to form a composite film. The composite film is carried from right to left, leaves the transfer device 100, and enters the die-cutting device 200. The die-cutting device 200 can trim the long strip of composite film into a sheet-like finished film of the desired configuration.

[0031] Specifically, the transfer device 100 includes: a first pressure roller group 110, which includes a first roller 111 and a second roller 112 arranged vertically side by side, through which the conductive cloth 1 and the release film 2 pass, and the first pressure roller group 110 can perform a first pressing on the conductive cloth 1 and the release film 2; and a second pressure roller group 120, which is located downstream of the first pressure roller group 110, which includes a third roller 121 and a fourth roller 122 arranged vertically side by side, through which the conductive cloth 1 and the release film 2 pass, and the second pressure roller group 120 can perform a second pressing on the conductive cloth 1 and the release film 2.

[0032] For details, please refer to Figure 2 and Figure 3 In the illustrated embodiment, the first pressure roller group 110 and the second pressure roller group 120 are spaced apart in the left-right direction, and the conductive cloth 1 and the release film 2 are conveyed from right to left. The first pressure roller group 110 is located on the right, and the conductive cloth 1 and the release film 2 enter the first pressure roller group 110 to begin the transfer; the second pressure roller group 120 is located on the left, and the conductive cloth 1 and the release film 2 leave the second pressure roller group 120 to end the transfer.

[0033] Conductive cloth 1 and release film 2 enter the first pressure roller group 110. The first roller 111 and the second roller 112 can press the conductive cloth 1 and the release film 2 to promote their adhesion. Subsequently, the conductive cloth 1 and the release film 2 enter the second pressure roller group 120. The third roller 121 and the fourth roller 122 can press the conductive cloth 1 and the release film 2 again to strengthen their adhesion.

[0034] Furthermore, the transfer device 100 also includes: a first positioning fixture 130, located upstream of the first pressure roller group 110, for guiding the conductive cloth 1 into the transfer device 100 along a preset path; and a second positioning fixture 140, located downstream of the second pressure roller group 120, for guiding the conductive cloth 1 out of the transfer device 100 along a preset path.

[0035] by Figure 1 Taking the finished film shown as an example, in order to ensure that multiple conductive cloths 1 have the required relative positions and extension states of the finished product, during the transfer process, it is necessary to ensure that each conductive cloth 1 extends in a straight line along the first horizontal direction, and also to ensure that all conductive cloths 1 are arranged in parallel at a preset distance along the second horizontal direction.

[0036] The first positioning fixture 130 and the second positioning fixture 140 are used to calibrate the position and extension direction of each conductive cloth 1, as well as the relative position of all conductive cloths 1.

[0037] In one embodiment, reference is made to Figure 6 The first positioning fixture 130 or the second positioning fixture 140 includes a substrate 131, which is used to support the conductive cloth 1; the surface of the substrate 131 is provided with a plurality of guide grooves 130a, any one of the guide grooves 130a extends along a first horizontal direction, and the plurality of guide grooves 130a are spaced apart along a second horizontal direction; any one of the guide grooves 130a is used to accommodate a conductive cloth 1.

[0038] The first horizontal direction, the second horizontal direction, and the vertical direction are perpendicular to each other. In a specific embodiment, the first horizontal direction can be regarded as the length direction of the conductive cloth 1, and the second horizontal direction can be regarded as the width direction of the conductive cloth 1.

[0039] In this embodiment, the guide groove 130a can not only limit the position and extension direction of each conductive cloth 1, but also limit the movement direction of the conductive cloth 1, ensuring that each conductive cloth 1 can move towards the first pressure roller group 110 and the second pressure roller group 120 along the first horizontal direction.

[0040] In another embodiment, refer to Figure 8 The first positioning fixture 130 or the second positioning fixture 140 includes: a base plate 131; a plurality of limiting blocks 132 disposed on the base plate 131, wherein any one of the limiting blocks 132 extends along a first horizontal direction and the plurality of limiting blocks 132 are spaced apart along a second horizontal direction.

[0041] In this embodiment, a guide groove 130a is formed between any two adjacent limiting blocks 132. At this time, the two adjacent limiting blocks 132 cooperate to limit the position and extension direction of a conductive cloth 1; the cooperation of multiple limiting blocks 132 can limit the relative position of multiple conductive cloths 1, thereby ensuring that all conductive cloths 1 are transferred in a preset position, in a preset state, and along a preset direction.

[0042] In another embodiment, the first positioning fixture 130 or the second positioning fixture 140 includes: a base plate 131; multiple rows of wheel sets, which are disposed on the base plate 131 along a first horizontal direction, each row of wheel sets including multiple rollers 136, each roller 136 being rotatably disposed on the base plate 131, the multiple rollers 136 in one row of wheel sets being arranged along a second horizontal direction; along the second horizontal direction, each roller 136 having a retaining ring 137 at both ends; the multiple rows of wheel sets being arranged side by side, the rollers 136 being arranged in an array, and any row of rollers 136 being used to support a conductive cloth 1.

[0043] For details, please refer to Figure 7 In the illustrated embodiment, the substrate 131 is provided with five rows and six columns of rollers 136. Multiple rollers 136 in a row of rollers are connected in series on a linkage rod. In this way, a row of rollers 136 can rotate synchronously, thereby ensuring the uniformity of the conductive cloth 1's conveyor belt.

[0044] Continue to refer to Figure 7 The outer diameter of the retaining ring 137 is larger than the outer diameter of the roller 136. Each roller 136 is located between two retaining rings 137, and a guide groove 130a is formed between the roller 136 and the retaining ring 137.

[0045] Continue to refer to Figure 7 Any column of rollers 136 is arranged along the first horizontal direction and can cooperate to support a conductive cloth 1. When the conductive cloth 1 is on the rollers 136, the two sides of the conductive cloth 1 in the width direction are limited by the retaining rings 137, and the extension direction of the conductive cloth 1 is limited by a column of retaining rings 137.

[0046] In this embodiment, since each roller 136 can rotate, when the conductive cloth 1 is being fed, the roller 136 can also offset the friction between itself and the conductive cloth 1 through its own rotation, thereby promoting the downstream feeding of the conductive cloth 1.

[0047] This application does not limit the specific configuration of the first positioning fixture 130 and the second positioning fixture 140.

[0048] By positioning each conductive cloth 1 with the first positioning fixture 130 and the second positioning fixture 140, and ensuring that multiple conductive cloths 1 are transferred onto the release film 2 in the preset position and in the preset state, the constructed composite film can be guaranteed to meet the process requirements.

[0049] Furthermore, the third roller 121 and the fourth roller 122 are active rollers. During the transfer process, the third roller 121 and the fourth roller 122 rotate synchronously and in opposite directions, which can pull the conductive cloth 1 and the release film 2 downstream. Since the position of the conductive cloth 1 is limited by the first positioning fixture 130 and the second positioning fixture 140, the composite film obtained by the transfer device 100 can have a uniform and stable configuration.

[0050] For details, please refer to Figure 2 In the illustrated embodiment, from right to left, a first positioning fixture 130, a first pressure roller group 110, a second pressure roller group 120, a second positioning fixture 140, and a die-cutting device 200 are arranged sequentially. The first positioning fixture 130 is used to calibrate multiple conductive fabrics 1 so that they enter the first pressure roller group 110 and the second pressure roller group 120 from right to left in a preset position and in a preset state.

[0051] Combined with reference Figure 3 The third roller 121 and the fourth roller 122 are arranged side by side in the vertical direction. The third roller 121 is positioned at the top and rotates clockwise, while the fourth roller 122 is positioned at the bottom and rotates counterclockwise. During the transfer process, the third roller 121 and the fourth roller 122 clamp the conductive cloth 1 and the release film 2. The pressure of the third roller 121 and the fourth roller 122 can perform a second pressing on the conductive cloth 1 and the release film 2. At the same time, the synchronous and counterclockwise rotation of the third roller 121 and the fourth roller 122 can continuously pull the conductive cloth 1 and the release film 2 downstream. In this way, the second pressure roller group 120 can both promote the pressing of the conductive cloth 1 and the release film 2 and provide traction force for the conveyor belt of the conductive cloth 1 and the release film 2.

[0052] Continue to refer to Figure 3 The first positioning fixture 130 and the second positioning fixture 140 are arranged side by side in the left-right direction, which can ensure that the conductive cloth 1 is in a preset position and maintains a preset state before entering the two sets of positioning fixtures and after leaving the two sets of positioning fixtures. In this way, it is beneficial to ensure that the conductive cloth 1 has the posture required by the process during the transfer process, thereby ensuring the stability of the composite film construction and the yield.

[0053] Specifically, the die-cutting device 200 includes: a cutting mechanism 210, located downstream of the second positioning fixture 140, for cutting the composite film to obtain a film sheet; a punching mechanism 220, located downstream of the cutting mechanism 210, for shaping the film sheet to obtain a finished film of the required size and shape; and a die-cutting positioning fixture 230 for receiving the shaped film sheet.

[0054] For details, please refer to Figure 2 In the illustrated embodiment, from right to left, a transfer device 100, a cutting mechanism 210, and a punching mechanism 220 are arranged sequentially. The composite film produced by the transfer device 100 continues to move to the left and enters the cutting mechanism 210, where it is cut off. The cut-off portion is the film sheet. The die-cutting positioning fixture 230 is used to carry the film sheet and calibrate its position and state, thereby ensuring that the film sheet shaped by the punching mechanism 220 has a uniform posture, thus guaranteeing the accuracy of the shaping effect.

[0055] To improve production efficiency, the conductive fabric 1 and release film 2 are typically prepared in roll form, which is formed by winding long strips of material. Before entering the transfer device 100, the roll is released by the unwinding device; the material is pulled by the third roller 121 and the fourth roller 122 and transferred into a composite film by the transfer device 100. During operation, the transfer device 100 can continuously bond the conductive fabric 1 and release film 2 to form a long strip of composite film, while the cutting mechanism 210 can continuously cut out film sheets; the cut film sheets are sent to the punching mechanism 220 for shaping. Thus, the transfer device 100 and the die-cutting device 200 work together to automatically and efficiently realize the production line preparation of finished films.

[0056] Furthermore, the die-cutting positioning fixture 230 is provided with a limiting component 231, which is correspondingly set with the conductive cloth 1 on the diaphragm and can calibrate the position and state of the diaphragm by limiting the conductive cloth 1.

[0057] The limiting component 231 can be similar to the upper limiting structure of the first positioning fixture 130 and the second positioning fixture 140 (such as a groove that can accommodate the conductive cloth 1, a plate or block that can abut against the side of the conductive cloth 1, etc.), and will not be described in detail here.

[0058] It should be explained that, since the transfer device 100 is provided with a first positioning fixture 130 and a second positioning fixture 140, the relative positions of multiple conductive cloths 1 on the release film 2, as well as the position and extension direction of each conductive cloth 1 on the release film 2, are determined and uniform in the composite film made by the transfer device 100.

[0059] Therefore, a die-cutting positioning fixture 230 is configured such that the limiting position of the upper limit component 231 of the die-cutting positioning fixture 230 is consistent with the limiting position of the upper limit structure of the first positioning fixture 130 and the second positioning fixture 140. When the die-cutting positioning fixture 230 receives the film, it ensures that the conductive cloth 1 on the film is in the limiting position of the limiting component 231. The die-cutting positioning fixture 230 can therefore receive the film in a uniform position and give the film a uniform state. In this way, it is beneficial for the punching mechanism 220 to shape each film on the die-cutting positioning fixture 230 into a uniform finished film shape.

[0060] More specifically, during operation, the transfer device 100 constructs a composite film, the cutting mechanism 210 cuts the composite film to obtain a film sheet, the die-cutting positioning fixture 230 receives the film sheet and places it in a preset position and has a preset state, and the punching mechanism 220 punches the film sheet to shape it and form a finished film.

[0061] The composite film preparation equipment provided in this application, through the linear layout transfer device 100 and the cutting mechanism 210, can efficiently and reliably continuously prepare finished films. Through the first positioning fixture 130 and the second positioning fixture 140, the conductive cloth 1 flowing during the transfer process can be limited to the required preset position and have a uniform preset state, thereby ensuring the yield of composite film preparation. In addition, with the die-cutting positioning fixture 230, the conductive cloth 1 in the composite film can be used as a reverse positioning tool to ensure that the punching mechanism 220 accurately acts on the film, further ensuring the yield of finished film preparation.

[0062] Optionally, the transfer device 100 further includes a roller drive mechanism 150, which drives the third roller 121 and the fourth roller 122 to rotate synchronously and in opposite directions.

[0063] The roller drive mechanism 150 can be a motor, rotary cylinder or other drive component that can drive the roller to rotate.

[0064] In one specific embodiment, the roller drive mechanism 150 includes two sets of motors, which are used to drive the third roller 121 and the fourth roller 122 to rotate respectively. The output end of the motor is also provided with a gearbox, which is used to regulate the rotation speed of the rollers to ensure that the third roller 121 and the fourth roller 122 rotate stably, synchronously and in opposite directions.

[0065] Additionally, in the transfer device 100, only the third roller 121 and the fourth roller 122 can be configured as active rollers, relying solely on the traction of the third roller 121 and the fourth roller 122 to promote the conductive cloth 1 and the release film 2 to move along the first horizontal direction. Alternatively, the first roller 111 and the second roller 112 can also be configured as active rollers. In this case, the first roller 111 and the second roller 112 can pull the conductive cloth 1 and the release film 2 into the transfer device 100, while the third roller 121 and the fourth roller 122 can pull the conductive cloth 1 and the release film 2 out of the transfer device 100. The two sets of active rollers working together can enhance the traction force and improve the reliability of the movement of the conductive cloth 1 and the release film 2.

[0066] It should be noted that when the first roller 111 and the second roller 112, the third roller 121 and the fourth roller 122 are all active rollers, the traction speed of the two sets of active rollers needs to be consistent. Alternatively, the traction speed of the third roller 121 and the fourth roller 122, which are located downstream, should be slightly greater than the traction speed of the first roller 111 and the second roller 112. This is beneficial for the conductive cloth 1 and the release film 2 to maintain tension during the conveyor belt operation.

[0067] Furthermore, when the first roller 111 and the second roller 112, the third roller 121 and the fourth roller 122 are all active rollers, two sets of roller drive mechanisms 150 can be provided to realize the rotation of the two sets of active rollers respectively. Alternatively, the first roller 111 and the third roller 121, which are vertically arranged on the top, can be linked (e.g., connected by meshing gears, synchronous belts, chains, or other linkage components), and the third roller 121 and the fourth roller 122, which are vertically arranged on the bottom, can be linked. In this way, only one set of roller drive mechanisms 150 is required, which drives the first roller 111 and the second roller 112 to rotate synchronously and in opposite directions, or drives the third roller 121 and the fourth roller 122 to rotate synchronously and in opposite directions. Thus, the rotation of the two sets of active rollers can be realized through linkage.

[0068] Additionally, if necessary, the first pressure roller group 110 and / or the second pressure roller group 120 may include two or more groups of rollers, each group comprising a pair of rollers arranged vertically, each group capable of pressing the conductive cloth 1 and the release film 2 once. Increasing the number of roller groups helps to enhance the bonding effect between the conductive cloth 1 and the release film 2.

[0069] Optionally, the transfer device 100 further includes a roller pressure adjustment mechanism 160 for adjusting the vertical distance between the first roller 111 and the second roller 112, as well as the vertical distance between the third roller 121 and the fourth roller 122.

[0070] It is easy to understand that the closer the rollers are, the greater the pressure between them, and the greater the pressure on the conductive cloth 1 and release film 2 located between the two rollers.

[0071] The roller pressure adjustment mechanism 160 is set up to facilitate the adjustment of the distance between the two rollers used to press the conductive cloth 1 and the release film 2, ensuring that the two rollers can press the conductive cloth 1 and the release film 2 tightly to achieve the pressing effect. When the composite film preparation materials are replaced or added or removed in the future, adaptive adjustments can be made as needed.

[0072] The roller pressure adjustment mechanism 160 can use automatic driving components such as cylinders or electric cylinders, so that the automatic driving component is connected to at least one of the pair of rollers, so that the pair of rollers can move closer or further apart under the drive of the automatic driving component, thereby realizing the adjustment of the vertical distance between the rollers.

[0073] Alternatively, the roller pressure adjustment mechanism 160 can use a manual actuator such as a hand-adjusting screw, micrometer, or set screw, so that the manual actuator is connected to at least one of the pair of rollers, allowing the pair of rollers to move closer or further apart under the action of the manual actuator, thereby achieving the adjustment of the vertical distance between the rollers.

[0074] In one embodiment, the roller pressing adjustment mechanism 160 includes two sets of adjustment components, one set of adjustment components is used to adjust the vertical distance between the first roller 111 and the second roller 112, and the other set of adjustment components is used to adjust the vertical distance between the third roller 121 and the fourth roller 122.

[0075] In another embodiment, the first roller 111 and the third roller 121, which are vertically arranged on the top, are linked together, and the third roller 121 and the fourth roller 122, which are vertically arranged on the bottom, are linked together. In this case, a set of adjustment components can realize the synchronous movement of the two pairs of rollers.

[0076] In one specific embodiment, the first roller 111 and the third roller 121 are spaced apart along a first horizontal direction, and the second roller 112 and the fourth roller 122 are also spaced apart along the first horizontal direction. The transfer device 100 further includes: a first pressure belt 113, sleeved on the first roller 111 and the third roller 121; a second pressure belt 114, sleeved on the second roller 112 and the fourth roller 122; and conductive cloth 1 and release film 2 passing through the first pressure belt 113 and the second pressure belt 114.

[0077] For details, please refer to Figure 3In the illustrated embodiment, the first pressure roller group 110 and the second pressure roller group 120 are spaced apart in the left-right direction, with the first pressure roller group 110 located on the left and the second pressure roller group 120 located on the right. The conductive cloth 1 and the release film 2 travel from left to right. In the first pressure roller group 110, the first roller 111 is located on top and the second roller 112 is located on the bottom; in the second pressure roller group 120, the third roller 121 is located on top and the fourth roller 122 is located on the bottom. The first roller 111 and the third roller 121 are arranged side by side in the left-right direction, and the second roller 112 and the fourth roller 122 are also arranged side by side in the left-right direction. A first pressure belt 113 is sleeved on the first roller 111 and the third roller 121. The third roller 121 is the driving roller. When the third roller 121 rotates clockwise, it drives the first roller 111 to rotate clockwise synchronously through the first pressure belt 113. The second roller 112 and the fourth roller 122 are fitted with a second pressure belt 114. The fourth roller 122 is the driving roller. When the fourth roller 122 rotates counterclockwise, it drives the second roller 112 to rotate counterclockwise synchronously through the second pressure belt 114.

[0078] At this time, the rollers in the first pressure roller group 110 and the second pressure roller group 120 are both active rollers, which can provide stable and reliable traction force to facilitate the downstream movement of the conductive cloth 1 and the release film 2. Simultaneously, after the conductive cloth 1 and the release film 2 enter the transfer device 100, they are always positioned between the first pressure belt 113 and the second pressure belt 114. The second pressure belt 114 supports the conductive cloth 1 and the release film 2, preventing them from sagging during the conveying process and ensuring they remain flat. Furthermore, the first pressure belt 113 and the second pressure belt 114 also work together to compact the conductive cloth 1 and the release film 2, ensuring that the conductive cloth 1 and the release film 2 are constantly subjected to pressure during the conveying process, thereby further improving the yield of the composite film preparation.

[0079] Combined with reference Figure 4 The roller adjustment mechanism 160 includes: an upper support 161, in which a first roller 111 and a third roller 121 are rotatably mounted; a lower support 162, in which a second roller 112 and a fourth roller 122 are rotatably mounted; an adjustment support 163, in which a vertically extending adjustment guide rail 164 is provided, and the upper support 161 is slidably mounted on the adjustment guide rail 164; and a manual adjustment screw 165, rotatably mounted vertically in the adjustment support 163, with the upper support 161 threadedly connected to the manual adjustment screw 165 via a nut. When the vertical distance between the rollers needs to be adjusted, the operator rotates the manual adjustment screw 165, and the upper support 161 moves vertically along the adjustment guide rail 164.

[0080] Furthermore, by using the roller pressure adjustment mechanism 160 to keep the first roller 111 and the second roller 112 away from each other, and the third roller 121 and the fourth roller 122 away from each other, it is also convenient to thread and change the conductive cloth 1 and the release film 2.

[0081] Optionally, the rollers in the first pressure roller group 110 and the second pressure roller group 120 are rubber rollers, and the surface of the rollers is covered with flexible materials (such as rubber, plastic, etc.). Since the flexible materials have a certain elasticity, when the rollers cooperate to press against the conductive cloth 1 and the release film 2, the roller surfaces can be deformed, thus ensuring pressure while avoiding rigid damage.

[0082] Optionally, the surfaces of the first pressure band 113 and / or the second pressure band 114 are provided with pressure strips, the positions of which correspond to the conductive cloth 1; when the conductive cloth 1 is between the first pressure band 113 and the second pressure band 114, the pressure strips press against the conductive cloth 1.

[0083] For example, in the composite film, eight conductive cloth strips 1 are attached to the release film 2. Correspondingly, the first pressure strip 113 and / or the second pressure strip 114 are provided with eight pressure strips on the surface of the conductive cloth 1 to press against it. After the conductive cloth 1 enters the first pressure strip 113 and the second pressure strip 114, it can be pressed against by the pressure strips.

[0084] Because the pressure strip at the location of the pressure strip is thick, the conductive cloth 1 and release film 2, which are pressed between the two sets of pressure strips, are further restricted by the pressure strip, resulting in a better pressing effect and making it easier for the conductive cloth 1 and release film 2 to bond together.

[0085] Optionally, the pressure strip is made of a flexible material (such as rubber, plastic, etc.). In this way, the pressure strip can easily change direction with the pressure belt, and the pressure strip can also be deformed under pressure during extrusion and apply the pressure in the opposite direction to the conductive cloth 1 and the release film 2, thereby promoting the bonding of the two.

[0086] Optionally, the transfer device 100 further includes a release film unwinding mechanism 170, located upstream of the first pressure roller group 110, for releasing the release film 2.

[0087] Specifically, the release film unwinding mechanism 170 includes a rotatable drum. A strip of release film 2 material is rolled into a roll, which is then fitted onto the drum. The free end of the roll passes through the transfer device 100 and is pressed by the first pressure roller group 110 and the second pressure roller group 120. During operation, the third roller 121 and the fourth roller 122 rotate synchronously and in opposite directions, pulling the release film 2 along the conveyor belt. The drum rotates, continuously releasing the release film 2.

[0088] In this system, the material cylinder can rotate passively; when the release film 2 is pulled, the pulling force acts in the opposite direction on the material roll, causing the material roll to drive the material cylinder to rotate and release the force. The material cylinder can also rotate actively, for example, by setting a drive mechanism such as a motor or magnetic powder box to drive the material cylinder to rotate; the active rotation of the material cylinder releases the release film 2, which is coordinated with the conveyor belt operation of the release film 2.

[0089] To facilitate the expansion and tightening of the material roll in the barrel, and thus enable rotational unwinding, the barrel can be made of an air-expanding shaft or a slip shaft.

[0090] Optionally, the transfer device 100 further includes a conductive cloth unwinding mechanism located upstream of the first pressure roller group 110 for releasing the conductive cloth 1.

[0091] The structure of the conductive fabric unwinding mechanism is similar to that of the release film unwinding mechanism 170, and will not be described in detail here. It should be noted that, since the composite film requires multiple conductive fabrics to be bonded to a single release film, the conductive fabric unwinding mechanism includes multiple rotatable cylinders, any one of which is used to rotate and release a roll of conductive fabric 1.

[0092] Optionally, the transfer device 100 also includes an auxiliary feeding plate 180, which is located upstream of the first positioning fixture 130 and is used to support the conductive cloth 1. The surface of the auxiliary feeding plate 180 that contacts the conductive cloth 1 is a smooth surface.

[0093] For details, please refer to Figure 2 In the illustrated embodiment, an auxiliary feeding plate 180 is located on the right side of the first positioning fixture 130. The conductive cloth 1 is laid flat on the auxiliary feeding plate 180 and travels from right to left along the first horizontal direction. The auxiliary feeding plate 180 can support the conductive cloth 1 and ensure that the conductive cloth 1 enters the first positioning fixture 130 in a flat state. At the same time, the upper surface of the auxiliary feeding plate 180 is a smooth surface, so the friction between the conductive cloth 1 and the auxiliary feeding plate 180 is minimal when the cloth travels. The smooth surface of the auxiliary feeding plate 180 can also promote the travel of the conductive cloth 1.

[0094] Optionally, Teflon tape is adhered to the auxiliary feeding plate 180. The smooth adhesive side of the Teflon tape effectively reduces the friction of the conductive cloth 1 during transport.

[0095] Optionally, the transfer device 100 further includes an auxiliary positioning fixture 191, which is disposed on the first positioning fixture 130 or the second positioning fixture 140 and is used to block the top opening of the guide groove 130a; the conductive cloth 1 and the release film 2 pass through the auxiliary positioning fixture 191 and the first positioning fixture 130. The auxiliary positioning fixture 191 can both confine the conductive cloth 1 in the guide groove 130a and pre-apply the conductive cloth 1 and the release film 2.

[0096] Taking the example of an auxiliary positioning fixture 191 on the first positioning fixture 130, it is easy to understand that the first positioning fixture 130 is mainly used to limit the horizontal position of the conductive cloth 1. When the conductive cloth 1 travels along the guide groove 130a, vertical displacement may occur.

[0097] To this end, an auxiliary positioning fixture 191 is added to the guide groove 130a so that the conductive cloth 1 passes between the first positioning fixture 130 and the auxiliary positioning fixture 191. The guide groove 130a can limit the horizontal position and direction of movement of the conductive cloth 1, and the auxiliary positioning fixture 191 can limit the vertical range of movement of the conductive cloth 1 and prevent the conductive cloth 1 from vertically shifting or even leaving the guide groove 130a.

[0098] During the transfer process, the conductive cloth 1 is placed in the guide groove 130a and moves along the guide groove 130a in the first horizontal direction. The top of the conductive cloth 1 is always blocked by the auxiliary positioning fixture 191, so that the conductive cloth 1 can be stably held in the guide groove 130a.

[0099] In one embodiment, the first positioning fixture 130 includes a base plate 131, the surface of which is provided with a plurality of guide grooves 130a, and the auxiliary positioning fixture 191 is arranged in the shape of an elongated strip and extends along the second horizontal direction on the base plate 131 and is mounted above all the guide grooves 130a.

[0100] In other embodiments, the auxiliary positioning fixture 191 may also be configured as a cover, covering the first positioning fixture 130, for limiting the conductive cloth 1; or, the auxiliary positioning fixture 191 may also be configured as a plug, capable of being inserted into the guide groove 130a, thereby limiting the vertical movement range of the conductive cloth 1 by reducing the height of the guide groove 130a.

[0101] This application does not limit the specific configuration of the auxiliary positioning fixture 191.

[0102] Figure 6 In the embodiment shown, the auxiliary positioning fixture 191 is generally in the shape of a bridge, including a crossbar extending along the second horizontal direction and supports at both ends of the crossbar. The supports are fixed to the first positioning fixture 130, so that the crossbar can block the top opening of the first positioning fixture 130, block all the top openings of the guide groove 130a, and hinder the vertical movement of the conductive cloth 1.

[0103] Furthermore, before the release film 2 enters the first pressure roller group 110, it first passes through the auxiliary positioning fixture 191. See reference [link / reference needed] for details. Figure 2 and Figure 3 In the illustrated embodiment, the release film unwinding mechanism 170 is located above the first pressure roller group 110. The release film 2 extends downwards from left to right, passes around the auxiliary positioning fixture 191, and then enters the first pressure roller group 110 along the second horizontal direction. At this time, the auxiliary positioning fixture 191 can support, tension, and guide the release film 2. Simultaneously, as the release film 2 passes through the auxiliary positioning fixture 191 and the first positioning fixture 130 together with the conductive cloth 1, the auxiliary positioning fixture 191 can also press against the conductive cloth 1 and the release film 2, thus playing a pre-applied role.

[0104] Optionally, the auxiliary positioning fixture 191 is detachably mounted on the first positioning fixture 130.

[0105] For example, one of the auxiliary positioning fixture 191 and the first positioning fixture 130 is provided with a magnet and the other is provided with a metal material. In this way, the auxiliary positioning fixture 191 and the first positioning fixture 130 can be connected by magnetic attraction to overcome magnetic force, and the connection between the auxiliary positioning fixture 191 and the first positioning fixture 130 can be easily released.

[0106] For example, one of the auxiliary positioning fixture 191 and the first positioning fixture 130 is provided with a locking block and the other is provided with a locking slot. When the locking block is inserted into the locking slot, the auxiliary positioning fixture 191 and the first positioning fixture 130 can be connected. When the locking block is disengaged from the locking slot, the connection between the auxiliary positioning fixture 191 and the first positioning fixture 130 can be released.

[0107] For example, one of the auxiliary positioning fixture 191 and the first positioning fixture 130 is provided with a hook and the other is provided with a buckle. When the buckle is engaged in the hook, the auxiliary positioning fixture 191 and the first positioning fixture 130 can be connected. When the buckle is disengaged from the hook, the connection between the auxiliary positioning fixture 191 and the first positioning fixture 130 can be released.

[0108] The auxiliary positioning fixture 191 and the first positioning fixture 130 are detachably connected. The auxiliary positioning fixture 191 can be selected as needed. When it is necessary to re-thread the conductive cloth 1, the auxiliary positioning fixture 191 can be removed to facilitate the placement of the conductive cloth 1 in the first positioning fixture 130. The relative position of the auxiliary positioning fixture 191 and the first positioning fixture 130 can be adjusted, or the number of auxiliary positioning fixtures 191 placed on the first positioning fixture 130 can be increased or decreased, depending on the conveyor speed and other factors, to meet more diverse positioning needs.

[0109] Optionally, the auxiliary positioning fixture 191 includes an elastic pressure conductive cloth 1 and a release film 2.

[0110] For example, the auxiliary positioning fixture 191 has an elastic pressure block on one side for pressing the conductive cloth 1. The elastic pressure block can be made of elastic materials such as rubber and plastic, or it can have the characteristics of force displacement by connecting elastic elements such as springs and spring sheets.

[0111] This allows the auxiliary positioning fixture 191 to elastically press against the conductive cloth 1 and the release film 2, ensuring the pre-attached pressure without hindering the conveying of the conductive cloth 1 and the release film 2.

[0112] Optionally, the auxiliary positioning fixture 191 is provided with multiple rollers on the side facing the conductive cloth 1. The rollers are arranged one-to-one with the guide grooves 130a and are used to press against the conductive cloth 1. The rollers can press the conductive cloth 1 and the release film 2 against the first positioning fixture 130. When the conductive cloth 1 and the release film 2 are conveyed, the rollers can also offset the friction force and promote the conveying by rolling.

[0113] Optionally, the first positioning fixture 130 is provided with two sets of auxiliary positioning fixtures 191, which are spaced apart along the first horizontal direction. The release film 2 extends around the first set of auxiliary positioning fixtures 191 and toward the second set of auxiliary positioning fixtures 191, which is located at the discharge end of the first positioning fixture 130.

[0114] For details, please refer to Figure 3 In the illustrated embodiment, two sets of auxiliary positioning fixtures 191 are spaced apart along the left-right direction on the first positioning fixture 130. The first set of auxiliary positioning fixtures 191 is located on the right, near the feed end of the first positioning fixture 130; the second set of auxiliary positioning fixtures 191 is located on the left, near the discharge end of the first positioning fixture 130. The release film unwinding mechanism 170 is located on the upper left of the first positioning fixture 130. The release film 2 extends downwards from left to right, passes around the first set of auxiliary positioning fixtures 191, and then extends horizontally from right to left into the second set of auxiliary positioning fixtures 191.

[0115] Two sets of auxiliary positioning fixtures 191 are set up so that the conductive cloth 1 can be vertically limited when it enters the first positioning fixture 130 and can also be vertically limited when it leaves the first positioning fixture 130. The two sets of auxiliary positioning fixtures 191 work together to ensure that the section of conductive cloth 1 on the first positioning fixture 130 has a reliable restricted state, thereby ensuring the restricted effect of the conductive cloth 1.

[0116] When the auxiliary positioning fixture 191 is detachably mounted on the first positioning fixture 130, multiple sets of auxiliary positioning fixtures 191 can be prepared. The number of auxiliary positioning fixtures 191 on the first positioning fixture 130 can be increased or decreased, and the position of the auxiliary positioning fixtures 191 can be changed according to actual production needs, thereby optimizing the limiting effect.

[0117] For example, the auxiliary positioning fixture 191 is attached to the first positioning fixture 130 by a magnet. When in use, the auxiliary positioning fixture 191 can be installed, removed or moved as needed to easily adjust its position and effect.

[0118] It should be added that an auxiliary positioning fixture 191 can also be set on the second positioning fixture 140, the details of which will not be elaborated here. In this case, the auxiliary positioning fixture 191 can also maintain the transfer effect of the composite film.

[0119] Optionally, the transfer device 100 further includes a corner buffer block 192. When the release film 2 passes around the auxiliary positioning fixture 191, the corner buffer block 192 is located between the release film 2 and the auxiliary positioning fixture 191 and can contact the side edge of the release film 2.

[0120] For details, please refer to Figure 2 and Figure 3In the illustrated embodiment, the first positioning fixture 130 is provided with two sets of auxiliary positioning fixtures 191, which are spaced apart in the left-right direction. The first set of auxiliary positioning fixtures 191 is located on the right, and the second set of auxiliary positioning fixtures 191 is located on the left. A corner buffer block 192 is provided above the first set of auxiliary positioning fixtures 191. When the release film 2 extends from left to right and tilts downward toward the first set of auxiliary positioning fixtures 191, the corner buffer block 192 is located between the release film 2 and the first set of auxiliary positioning fixtures 191. The right end of the corner buffer block 192 can abut against the release film 2, and the upper surface of the corner buffer block 192 can support the side of the release film 2 in the width direction, thereby playing a certain buffering role and preventing the release film 2 from being worn by the auxiliary positioning fixtures 191 due to the change in direction of the traction force during the process of passing around the auxiliary positioning fixtures 191.

[0121] Optionally, the corner buffer block 192 is made of a flexible material, which can prevent the release film 2 from being damaged when it changes direction.

[0122] The flexible material can be foam, sponge, rubber, etc. Flexible materials possess excellent stress deformation characteristics, serving both as shock absorbers and buffers without damaging the release film 2 or hindering its conveying. Furthermore, as the release film 2 roll is continuously released and its size decreases, the angle at which the release film 2 extends towards the auxiliary positioning fixture 191 changes. The flexible material can adapt to these positional changes through its own deformation, ensuring the buffering effect is achieved.

[0123] Optionally, the corner buffer block 192 is detachably mounted on the auxiliary positioning fixture 191.

[0124] For example, the corner buffer block 192 is magnetically attached to the auxiliary positioning fixture 191 by a magnet.

[0125] For example, the corner buffer block 192 is screwed onto the auxiliary positioning fixture 191 by screws and screw holes.

[0126] For example, the corner buffer block 192 is clamped onto the auxiliary positioning fixture 191 by a chuck.

[0127] By detachably connecting the corner buffer block 192 to the auxiliary positioning fixture 191, the corner buffer block 192 can be easily replaced after wear. Different configurations of the corner buffer block 192 can also be used depending on the angle at which the release film 2 extends toward the auxiliary positioning fixture 191.

[0128] Optionally, the corner buffer block 192 is configured as an inclined surface near the upper surface of the release film 2, and the inclined surface is in the same direction as the extension direction of the release film 2. The inclined surface can support the release film 2.

[0129] For details, please refer to Figure 2 In the illustrated embodiment, the right side of the corner buffer block 192 is an inclined surface sloping downwards from left to right. The corner buffer block 192 is positioned above the auxiliary positioning fixture 191 and inserted between the release film 2 and the auxiliary positioning fixture 191. The release film unwinding mechanism 170 is located above the left side of the first positioning fixture 130, and the release film 2 extends downwards from left to right. Before winding around the auxiliary positioning fixture 191, the release film 2 adheres to the inclined surface of the corner buffer block 192. In this way, the corner buffer block 192 can effectively support the release film 2 and ensure the conveyor position and conveyor stability of the release film 2.

[0130] To improve the applicability of the positioning fixture, in one embodiment, the first positioning fixture 130 or the second positioning fixture 140 includes: a base plate 131; a plurality of limiting blocks 132 disposed on the base plate 131, wherein any one of the limiting blocks 132 extends along a first horizontal direction, the plurality of limiting blocks 132 are spaced apart along a second horizontal direction, and a guide groove 130a is formed between any two adjacent limiting blocks 132; wherein the spacing between the limiting blocks 132 is adjustable along the second horizontal direction.

[0131] This increases the spacing between the limiting blocks 132 and the width of the guide groove 130a between two adjacent limiting blocks 132, so as to limit the conductive cloth 1 with a wider width; similarly, it decreases the spacing between the limiting blocks 132 and the width of the guide groove 130a, so as to limit the conductive cloth 1 with a narrower width.

[0132] Therefore, by setting the spacing of the limiting blocks 132 to be adjustable, the positioning fixture can limit the conductive cloth 1 of more specifications, thereby meeting the transfer needs of more composite films.

[0133] In one embodiment, the first positioning fixture 130 or the second positioning fixture 140 further includes an attachment block. The attachment block can be detachably attached to the side wall of the limiting block 132 by means of snap-fit, insertion, adhesion, adsorption, etc. After the attachment block is installed, the wall thickness of the limiting block 132 increases and the width of the guide groove 130a decreases. By stacking different numbers of attachment blocks, the width of the guide groove 130a can be changed.

[0134] In other embodiments, the limiting block 132 can be movably disposed on the substrate 131, and the width of the guide groove 130a can be adjusted by moving the limiting block 132 and changing the position of each limiting block 132.

[0135] In one specific embodiment, the first positioning fixture 130 or the second positioning fixture 140 further includes: a guide rod 133, which is connected between any two adjacent limiting blocks 132, the guide rod 133 extending along a second horizontal direction, and the limiting blocks 132 slidably disposed on the guide rod 133; and a limiting sleeve 134, which is disposed on any guide rod 133, and is located between two adjacent limiting blocks 132; the limiting blocks 132 are pulled apart by the guide rod 133, and the distance between the limiting blocks 132 is the farthest when the two adjacent limiting blocks 132 move to the extreme positions at both ends of the guide rod 133 between them; the limiting blocks 132 are pushed closer by the guide rod 133, and the distance between the limiting blocks 132 is the shortest when the two adjacent limiting blocks 132 move to press against the limiting sleeve 134 between them.

[0136] For details, please refer to Figure 8 In the illustrated embodiment, the substrate 131 is provided with five limiting blocks 132, and the five limiting blocks 132 form four guide grooves 130a. A guide rod 133 is slidably connected between any two adjacent limiting blocks 132; each limiting block 132 is provided with a sliding sleeve 135, which is sleeved on the guide rod 133 and can move along the guide rod 133 in the second horizontal direction. Each guide rod 133 is also sleeved with a limiting sleeve 134; two adjacent limiting blocks 132 approach each other and eventually abut against the limiting sleeve 134, clamping the limiting sleeve 134 between the two limiting blocks 132.

[0137] Continue to refer to Figure 8 The first limiting block 132 on the right is a fixed block and will not move along the second horizontal direction. The other limiting blocks 132 are slidably mounted on the base plate 131, which also has guide grooves and guide rails for guiding components. The other limiting blocks 132 are slidably mounted on the guide components and, restricted by the guide components, can only move along the second horizontal direction. This causes the last limiting block 132 on the left to translate, changing the width of the guide groove 130a through a linkage mechanism.

[0138] Continue to refer to Figure 8 When each limiting block 132 is at the end of the guide rod 133, and two adjacent limiting blocks 132 are at the two ends of the same guide rod 133, the distance between the limiting blocks 132 is the largest.

[0139] Continue to refer to Figure 8 Push the last limiting block 132 from left to right. With the linkage of the guide rod 133 and the limiting action of the sliding sleeve 135, each limiting block 132 will eventually abut against the sliding sleeve 135, and each sliding sleeve 135 will be sandwiched between two limiting blocks 132. At this time, the distance between the limiting blocks 132 is the smallest.

[0140] Since the maximum distance is limited by the guide rod 133 and the minimum distance is limited by the sliding sleeve 135, in this embodiment, the limiting block 132 has two reliable preset distances, and the positioning fixture can be used to limit the conductive cloth 1 of two specifications.

[0141] To facilitate the movement of the limit block 132, automatic driving components such as cylinders and electric cylinders can be set up so that the automatic driving components are connected to the last limit block 132 set on the left, and the distance is adjusted by the active translation of the last limit block 132 in conjunction with other limit blocks 132.

[0142] Alternatively, a screw, micrometer, or other manual actuator can be used to connect the manual actuator to the last limit block 132 located on the left, so that the limit block 132 can be manually moved along the second horizontal direction.

[0143] This allows the limiting block 132 to translate and change the width of the guide groove 130a without changing the interval between two adjacent guide grooves 130a, thus adapting to processes where only the width specification of the conductive cloth 1 is adjusted without adjusting the arrangement of the conductive cloth 1.

[0144] In one embodiment, after the transfer device 100 prepares the composite film, the operator pulls the free end of the composite film to the cutting station of the cutting mechanism 210; after a film is cut off, the operator sends it into the die-cutting positioning fixture 230; at the same time, the operator can pick up the free end of the composite film again, and in accordance with the transfer speed of the composite film, pull the composite film to the cutting station to wait for the next cutting.

[0145] To improve production efficiency, in another embodiment, the cutting mechanism 210 includes: a traction assembly 211 for pulling the composite film to the cutting station; and a cutter 212 disposed at the cutting station for cutting the composite film to obtain a film sheet.

[0146] Optionally, the traction assembly 211 includes: a traction member for picking up the free end of the composite film; and a traction drive member for driving the traction member to reciprocate along a first horizontal direction. The traction member can be any structure that conveniently picks up the free end of the composite film, such as a gripper or suction cup; the traction drive member can be a drive structure that conveniently drives the traction member to reciprocate, such as a cylinder or electric cylinder.

[0147] For details, please refer to Figure 2 and Figure 5In the illustrated embodiment, conductive cloth 1 and release film 2 are conveyed from right to left, passing through transfer device 100 to form a composite film; traction component 211 is located on the left side of transfer device 100; during operation, the traction component picks up the free end of the composite film and moves from right to left in accordance with the production speed of the composite film; the traction component 211 can continuously pull the composite film towards the cutting station while ensuring the tension of the conveyor belt. After the composite film is pulled to the cutting station, the cutter 212 cuts the composite film, and the cut piece is the film sheet. At this time, the traction component 211 can continue to pull the film sheet to the left and send the film sheet into the die-cutting positioning fixture 230, or the film sheet can be taken away by a worker or other transfer mechanism (such as a robot, overhead crane, etc.); after the cutting station is vacant, the traction component moves from left to right and picks up the free end of the composite film again.

[0148] Thus, the composite film is transferred from the transfer device 100 to the cutting mechanism 210 by the picking and pulling of the traction component 211.

[0149] Optionally, the cutting mechanism 210 includes two sets of traction components 211. The first set of traction components 211 travels back and forth between the pick-up station and the cutting station, and the second set of traction components 211 travels back and forth between the cutting station and the die-cutting positioning fixture 230.

[0150] Specifically, during operation, the first traction component 211 grasps the free end of the composite film at the pick-up station and moves along the first horizontal direction, pulling the composite film to the cutting station. The second traction component 211 picks up the free end of the composite film at the cutting station. The first traction component 211 releases the composite film and returns to the pick-up station, fixing the composite film at the pick-up station. In this way, both ends of the composite film to be cut are simultaneously fixed by the first and second traction components 211, which is beneficial for the cutter 212 to accurately and efficiently cut the composite film. After the film is cut, the second traction component 211 carries the film towards the die-cutting positioning fixture 230, while the part fixed by the first traction component 211 during the cutting process becomes the new free end of the composite film, and the first traction component 211 can carry the free end directly to the cutting station.

[0151] In this way, the two sets of traction components 211 reciprocate and cooperate to quickly achieve the positioning and traction of the composite membrane, and at the same time achieve the transfer of the membrane sheet.

[0152] Optionally, the cutting mechanism 210 also includes a cutting drive, which can be a cylinder, electric cylinder or other driving mechanism. The cutting drive is used to drive the cutter 212 to move closer to or away from the composite film.

[0153] Specifically, after the composite film is pulled to the cutting station, the cutting drive causes the cutter 212 to approach and cut the composite film. After cutting, the cutting drive causes the cutter 212 to move away from the composite film to facilitate the transfer of the film sheet and the composite film.

[0154] Optionally, the cutting mechanism 210 also includes a cutting adjustment component 213 for adjusting the position of the cutter 212 so that the cutter 212 can cut films of different lengths.

[0155] It should be explained that the cutting mechanism 210 is used for rough cutting of the composite film; for example, the final required finished film is a square structure with a length of Acm and a width of Bcm, and the composite film prepared by the transfer device 100 has a width of B+1cm; the traction component 211 pulls the composite film to the cutting station, and the film sheet cut by the cutter 212 has a length of A+1cm and a width of B+1cm; the film sheet is sent to the punching mechanism 220, which is used for fine cutting of the composite film, and finally the film sheet is trimmed into a square structure with a length of Acm and a width of Bcm.

[0156] Before fine cutting, the composite film is coarsely cut by the cutting mechanism 210, which can quickly cut the composite film into strips, obtain the film sheet for easy die-cutting positioning fixture 230 to calibrate the position, and the fine cutting mechanism 220 to cut the film.

[0157] It is easy to understand that the required membrane size will vary depending on the process and the desired size of the finished product. In this case, by changing the position of the cutter 212 through the cutting adjustment component 213, the distance between the cutting position of the cutter 212 and the free end of the composite membrane can be changed, thus cutting membranes of different lengths.

[0158] The cutting and adjusting component 213 can be an automatic drive component such as a cylinder or an electric cylinder. The automatic drive component drives the cutter 212 to move along the first horizontal direction, thereby changing the position of the cutter 212 in cutting the composite film so that the cutter 212 can cut film sheets of different lengths.

[0159] Alternatively, the cutting adjustment component 213 can be a manually adjustable component such as a screw, micrometer, or set screw. By manually adjusting the component, the cutter 212 can move along the first horizontal direction, thereby changing the position of the cutter 212 in cutting the composite film, so that the cutter 212 can cut film sheets of different lengths.

[0160] This application does not limit the specific configuration of the trimming and adjustment component 213.

[0161] Optionally, the cutting mechanism 210 also includes a transfer component 214 for receiving the diaphragm and transferring the diaphragm to the die-cutting positioning fixture 230.

[0162] The transmission component 214 can be a structure that facilitates the acquisition and transfer of the diaphragm, such as a conveyor belt, a transmission platform, a suction cup, or an overhead crane.

[0163] In one embodiment, the cutting mechanism 210 includes a traction component 211, a cutter 212, and a transmission component 214. The traction component 211 travels back and forth between the pick-up station and the cutting station, and the transmission component 214 travels back and forth between the cutting station and the die-cutting positioning fixture 230. After the traction component 211 picks up the free end of the composite film at the pick-up station, it can pull the composite film to the cutting station so that the cutter 212 can cut out the film sheet. After obtaining the film sheet, the traction component 211 returns to the pick-up station to pick up the free end of the composite film again, while the transmission component 214 can take away the film sheet and send it into the die-cutting positioning fixture 230.

[0164] In one embodiment, the punching mechanism 220 includes: a receiving platform 221 for mounting the die-cutting positioning fixture 230; a punching drive assembly for driving the receiving platform 221 to move back and forth between the loading / unloading station and the punching station; and a punching die, located at the punching station, for punching the film and achieving shaping.

[0165] For details, please refer to Figure 6 In the illustrated embodiment, the punching mechanism 220 also includes a housing, in which the punching die is suspended; the receiving platform 221 can move in and out of the housing under the drive of the punching drive assembly. In this way, the housing can both hide and protect the punching die, and also avoid the safety hazards of the punching die being exposed to the outside.

[0166] The punching drive assembly can be driven by pneumatic cylinders, electric cylinders, or other similar components.

[0167] During punching, the punching drive assembly drives the receiving table 221 to leave the machine housing and pick up the film at the loading and unloading station; after the film is placed in the die-cutting positioning fixture 230, the punching drive assembly drives the receiving table 221 to return to the machine housing and accept the punching die at the punching station.

[0168] Furthermore, the die-cutting positioning fixture 230 is also equipped with a punching die, which is used to shape the film in conjunction with the punching die.

[0169] For example, in a punching die and a punching tool, one is a die cavity and the other is a punch. During the punching process, the punch is inserted into the die cavity to cut the diaphragm. Alternatively, the punching die and the punching tool may be tangent blades. During the punching process, the corresponding blades move closer together until they are tangent to each other, thus cutting the diaphragm.

[0170] By setting up a punching die in conjunction with a punching die, the film can be shaped. This not only improves cutting efficiency and ensures cutting effect, but also plays a certain role in limiting and calibrating. Before punching, it is confirmed that the punching die is aligned with the corresponding punching die. During punching, it is confirmed that the punching die and the corresponding punching die interact with each other. This is conducive to the reliability and accuracy of shaping.

[0171] In one embodiment, the punching die includes: four punching blades 222, which are arranged along the four sides of a square and are used to punch the film into a square of a preset size; a plurality of punching posts 223, which are disposed within the square frame formed by the four punching blades 222 and are used to punch positioning round holes in the film; the punching die includes: four blade dies 232, which are arranged along the four sides of a square, a limiting component 231 disposed within the square frame formed by the four blade dies 232, and the blade dies 232 are correspondingly disposed to the punching blades 222; a plurality of round hole dies 233, which are distributed around the limiting component 231 and are correspondingly disposed to the punching posts 223.

[0172] For details, please refer to Figure 10 In the illustrated embodiment, four cutting blades 222 are arranged in a square, with their ends close together. Correspondingly, four blade dies 232 are also arranged in a square, with their ends close together. The size of the diaphragm is larger than the size of the square formed by the blades and dies. When the die-cutting positioning fixture 230 supports the diaphragm, the projection of the diaphragm onto the die-cutting positioning fixture 230 completely covers the square formed by the blade dies 232. During cutting, the cutting blades 222 and blade dies 232 are aligned one-to-one. The cutting blades 222 are inserted into the blade dies 232, which trims the four sides of the diaphragm, adjusting the size of the diaphragm to the square size required for the finished film.

[0173] Continue to refer to Figure 10 Four cutting blades 222 form a square, within which two rows of cutting posts 223 are arranged at intervals along a second horizontal direction. Each row includes four cutting posts 223 arranged at intervals along a first horizontal direction. Correspondingly, the die-cutting positioning fixture 230 has two rows of round hole dies 233, the number and position of which correspond one-to-one with the cutting posts 223. During cutting, the cutting blades 222 are inserted into the blade dies 232, and the cutting posts 223 are inserted into the round hole dies 233. The cutting posts 223 can punch two sets of positioning round holes 3 on both sides of the diaphragm.

[0174] In other embodiments, an arc-shaped blade and a corresponding die can be provided to punch rounded corners at the four corners of the membrane; different shaped punching dies and corresponding shaped punching molds can also be provided to punch holes of different shapes on the membrane to meet different membrane process requirements.

[0175] Optionally, the limiting component 231 includes: a base plate; and multiple rows of limiting structures disposed on the base plate, wherein each row of limiting structures includes multiple limiting posts, the multiple limiting posts in a row of limiting structures are spaced apart along a first horizontal direction, and the multiple rows of limiting structures are spaced apart along a second horizontal direction.

[0176] The limiting post can be any structure that can conveniently hold the conductive cloth 1, such as a rod or block.

[0177] For details, please refer to Figure 9 In the illustrated embodiment, the base plate is provided with ten rows of limiting structures, which are spaced apart in the vertical direction. Each row of limiting structures includes four limiting posts, and the four limiting posts in the same row are spaced apart in the horizontal direction. Specifically, from top to bottom, the first and second rows of limiting structures form a limiting groove, which can cooperate to limit one conductive cloth 1; the third and fourth rows of limiting structures form another limiting groove, which can cooperate to limit another conductive cloth 1, and so on. The ten rows of limiting structures can cooperate to limit five conductive cloths 2.

[0178] Continue to refer to Figure 9 In the illustrated embodiment, the membrane has five conductive cloth strips 1, which are spaced apart vertically, and any one of the conductive cloth strips 1 extends horizontally. Before cutting and shaping, the membrane is placed into the die-cutting positioning fixture 230, so that the side of the membrane with the conductive cloth strip 1 contacts the base plate. Since the limiting structure is arranged according to the position of the conductive cloth strip 1 on the composite membrane, the limiting groove corresponds one-to-one with the conductive cloth strip 1. Therefore, when the operator or handling equipment (such as a robot, suction cup, etc.) places the membrane, it is ensured that each conductive cloth strip 1 enters the corresponding limiting groove, and the conductive cloth strip 1 and the limiting groove can limit each other.

[0179] It is easy to understand that since the position of the conductive cloth 1 on the diaphragm is determined, when the position of the conductive cloth 1 on the die-cutting positioning fixture 230 is determined, the position of the diaphragm on the die-cutting positioning fixture 230 must also be determined.

[0180] Therefore, when the limiting groove and the conductive cloth 1 are in a one-to-one correspondence, the diaphragm carried by the die-cutting positioning fixture 230 must have a uniform position and state so that the punching mechanism 220 can perform uniform punching and shaping.

[0181] Optionally, any two rows of adjacent limiting structures are staggered along the first horizontal direction.

[0182] For details, please refer to Figure 9 In the illustrated embodiment, from top to bottom, the odd-numbered rows of limiting structures (first, third, fifth, etc.) are arranged side by side, while the even-numbered rows of limiting structures (second, fourth, sixth, etc.) are arranged side by side. The limiting structures adjacent to the first, second, third, and fourth rows are staggered. The even-numbered rows of limiting structures are positioned to the left compared to the odd-numbered rows.

[0183] Continue to refer to Figure 9When the first and second rows of limiting structures cooperate to clamp the conductive cloth 1, the upper side of the conductive cloth 1 is supported by the first row of limiting structures, and the lower side is supported by the second row of limiting structures. Because the supporting positions of the two rows of limiting structures are different, more positions on a conductive cloth 1 are subject to the limiting effect. In this way, it is beneficial to ensure the constrained stability of the conductive cloth 1 and further avoid the film from being displaced or deformed by force during the cutting and shaping process.

[0184] Optionally, the limiting post is flexibly set on the base plate.

[0185] For example, the base plate of the die-cutting positioning fixture 230 has multiple rows and columns of mounting holes. Each mounting hole is used to install a limiting post. The limiting component 231 also includes an elastic element, which can be made of elastic materials such as rubber or plastic, or it can be an elastic structure such as a spring or sheet. The elastic element is located in the mounting hole, with one end connected to the limiting post and the other end connected to the base plate. The elastic element has the characteristics of deformation under force and recovery after unloading force. This allows the limiting post to be elastically set on the base plate. When the diaphragm is supported by the limiting post and suspended on the base plate, the punching tool can contact and press down on the diaphragm. At this time, the limiting post is compressed, and the pressure causes the elastic element to compress and deform. The limiting post retracts into the mounting hole so that the diaphragm can fall onto the base plate. With the diaphragm supported by the base plate, it can be ensured that the tool accurately and stably cooperates with the shape punching die and the hole punching die to achieve cutting and shaping. In addition, when the elastic element is compressed and deformed, it can also prevent the punching die from rigidly colliding with the die-cutting positioning fixture 230, thereby preventing the diaphragm set on the limiting component 231 from being damaged by impact; at the same time, the elastic element has the tendency to return to its original shape, and its elastic force can press the diaphragm against the punching die in the opposite direction, thereby ensuring that the punching die acts on the diaphragm and further optimizing the shaping effect of the diaphragm.

[0186] In other embodiments, the head of the limiting post that contacts the diaphragm may be made of an elastic material, or the limiting post may be configured as two elastically connected parts (one part is fixedly mounted on the base plate, and the other part is elastically connected to the fixed part by an elastic element such as a spring).

[0187] Optionally, multiple limiting posts are arranged in an array; the spacing between the limiting posts is adjustable along the second horizontal direction.

[0188] The method for adjusting the spacing between the limit pins is similar to that for adjusting the spacing between the limit blocks 132, and will not be described in detail here.

[0189] This allows the spacing of the limiting posts to be adjusted so that the die-cutting positioning fixture 230 can be used to position and support diaphragms of different specifications.

[0190] Optionally, the die-cutting positioning fixture 230 is also provided with a limiting strip 234, which is used to limit the position of the die-cutting positioning fixture 230 receiving the film.

[0191] As mentioned above, the size of the diaphragm is larger than the square formed by the blade die 232. Therefore, although the die-cutting positioning fixture 230 can limit the position of the conductive cloth 1 through the limiting component 231, it cannot guarantee that the diaphragm will cover the blade die 232. If one side of the diaphragm does not completely cover the blade die 232, the punching mechanism 220 will not be able to cut the diaphragm on that side during cutting and shaping, which will inevitably result in the final product not meeting the process requirements.

[0192] Therefore, by adding a limiting strip 234 to the die-cutting positioning fixture 230, the limiting strip 234 can be used as the edge limiting strip of the diaphragm, ensuring that the conductive cloth 1 on the diaphragm is limited in the limiting component 231 and the side of the diaphragm abuts against the limiting strip 234, so that the diaphragm can be quickly and accurately confirmed to be placed in place.

[0193] The die-cutting positioning fixture 230 can be provided with four limiting strips 234. The four limiting strips 234 are respectively located on the four sides of the diaphragm. When the diaphragm is in place, the four limiting strips 234 can cooperate to limit the diaphragm within them.

[0194] Alternatively, two limiting strips 234 can be provided on the die-cutting positioning fixture 230. The two limiting strips 234 are arranged adjacent to each other. One limiting strip 234 is used to limit the long side of the diaphragm, and the other limiting strip 234 is used to limit the short side of the diaphragm. When the diaphragm is in place, one corner of the diaphragm is restricted by the two limiting strips 234. Since the diaphragm is square, when one corner of the diaphragm is restricted, the diaphragm will necessarily be in the preset position.

[0195] Optionally, the position of the limiting strip 234 on the die-cutting positioning fixture 230 is adjustable to limit films of different sizes.

[0196] It is easy to understand that this makes the position of the limiting strip 234 on the die-cutting positioning fixture 230 adjustable, so that the position of the limiting strip 234 can be adjusted according to the specifications of the diaphragm, thereby improving the applicability of the die-cutting positioning fixture 230.

[0197] The limiting strip 234 can be detachably connected to the die-cutting positioning fixture 230 by means of screwing, snap-fitting, magnetic attraction, etc., and multiple connection points are arranged accordingly. The limiting strip 234 can be installed at the appropriate connection point as needed to meet the limiting requirements of diaphragms of different specifications.

[0198] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
