[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0022] First, refer to Figure 1 , a finished composite film is shown, which is composed of a conductive cloth 1 and a release film 2 transferred together, and a plurality of conductive cloths 1 arranged side by side are attached to the release film 2; wherein any one conductive cloth 1 extends along a first horizontal direction, and a plurality of conductive cloths 1 are spaced apart along a second horizontal direction.

[0023] Continue to refer to Figure 1 Along the second horizontal direction, a row of circular positioning holes 3 are respectively provided on both sides of the finished composite film, and any row includes three circular positioning holes 3. The three circular positioning holes 3 in one row are arranged at intervals along the first horizontal direction.

[0024] Continue to refer to Figure 1 The finished composite membrane is also provided with two vertical positioning holes 4, the two vertical positioning holes 4 are arranged at intervals along the first horizontal direction, and any one of the vertical positioning holes 4 is extended along the second horizontal direction.

[0025] It is easy to understand that in order to cut out the finished composite film of the required shape and size, and cut out the required number, shape and position of positioning holes on the membrane, it is necessary to calibrate the position of the membrane and the punching tool before cutting to ensure that the tool can accurately act on the preset position of the membrane.

[0026] To this end, the present application provides a composite film positioning mechanism 100, comprising: a substrate 110; multiple rows of limit assemblies, arranged on the substrate 110, any row of limit assemblies including multiple limit columns 121, multiple limit columns 121 in a row of limit assemblies are arranged at intervals along a first horizontal direction, and multiple rows of limit assemblies are arranged at intervals along a second horizontal direction; an outer shape punching die, arranged on the substrate 110, for cooperating with the punching tool to correct the outer shape and size of the diaphragm, and the limit assemblies are surrounded by the outer shape punching dies; a hole punching die, arranged on the substrate 110, for cooperating with the punching tool to punch out positioning holes on the diaphragm, and the hole punching die is distributed around the limit columns 121.

[0027] For details, please refer to Figure 2 In the illustrated embodiment, ten rows of limiting components are arranged on the substrate 110, and the ten rows of limiting components are arranged at intervals in the vertical direction. Any row of limiting components includes four limiting posts 121, and the four limiting posts 121 in the same row are arranged at intervals in the left-right direction. From top to bottom, the first and second rows of limiting components constitute a limiting groove, which can cooperate to limit a conductive cloth 1, and the third and fourth rows of limiting components constitute another limiting groove, which can cooperate to limit another conductive cloth 1... and so on, ten rows of limiting components can cooperate to limit five conductive cloths 2.

[0028] Continue to refer to Figure 2 In the illustrated embodiment, five conductive cloths 1 are arranged on the membrane, and the five conductive cloths 1 are arranged at intervals in the vertical direction, and any conductive cloth 1 extends in the horizontal direction. Before cutting and shaping, the membrane is placed in the composite membrane positioning mechanism 100; so that one side of the membrane with the conductive cloth 1 contacts the substrate 110. Since the limiting components are arranged corresponding to the position of the conductive cloth 1 on the composite membrane, the limiting grooves correspond to the conductive cloth 1 one by one; therefore, when the operator or handling equipment (such as a manipulator, a suction cup, etc.) places the membrane, it is ensured that each conductive cloth 1 enters a corresponding limiting groove, and the conductive cloth 1 and the limiting groove can limit each other.

[0029] It is easy to understand that, since the position of the conductive cloth 1 on the membrane is determined, when the position of the conductive cloth 1 on the substrate 110 is determined, the position of the membrane on the substrate 110 is also necessarily determined.

[0030] Therefore, when the limiting grooves correspond to the conductive cloth 1 one by one, the membrane carried by the substrate 110 must have a uniform position and state, so that the punching tool can perform uniform cutting and shaping.

[0031] It should be explained that if the diaphragm is placed directly on the substrate 110 and the punching tool acts on the diaphragm, it will inevitably cut the substrate 110, which is easy to damage the substrate 110 and affect the limiting effect of the substrate 110 on the diaphragm.

[0032] Therefore, an outer shape punching die and a hole punching die are provided on the substrate 110. When cutting and shaping, the punching tool can be inserted into the outer shape punching die and the hole punching die, so that the substrate 110 can be protected, the action position of the punching tool can be limited, the action accuracy of the punching tool can be improved, and the reliability and flatness of cutting can be improved.

[0033] In one embodiment, the outer shape punching die or the hole punching die adopts a concave die, and the punching tool is a convex die with a blade end. When cutting and shaping, the convex die is inserted into the corresponding concave die to achieve cutting of the membrane.

[0034] In another embodiment, the punching tool is a punch with a blade end, and the outer shape punching die or the hole punching die has an oblique surface that can be tangent to the blade end of the punching tool. When cutting and shaping, the punching tool is tangent to the oblique surface and cooperates to cut the film.

[0035] The present application does not limit the specific configuration of the shape punching die and the hole punching die.

[0036] It should also be explained that the size of the membrane before shaping is usually larger than the size of the finished composite membrane.

[0037] For example, the final finished composite membrane is a square structure with a length of A cm and a width of B cm, and the membrane sheet to be shaped is a structure with a length greater than A cm and a width greater than B cm.

[0038] The shape punching die can cooperate with the punching tool to trim the shape and size of the diaphragm, so that the diaphragm is finally cut into a square structure with a length of Acm and a width of Bcm.

[0039] The punching die is used to cooperate with the punching tool to punch out positioning holes on the diaphragm. According to the requirements of subsequent processes and use, the positioning holes can be of any shape (such as the circular positioning holes and vertical positioning holes mentioned above), any number, and distributed at any position of the diaphragm.

[0040] In summary, the composite film positioning mechanism 100 provided in the present application sets multiple rows of limit components on the substrate 110, and utilizes the mutual limitation between the limit components and the conductive cloth 1, so that the film received by the composite film positioning mechanism 100 has a uniform posture, thereby ensuring the uniformity and accuracy of cutting and shaping; in conjunction with the shape punching die and the hole punching die, it can improve the cutting efficiency and ensure the cutting effect, and can also play a certain limit calibration role, thereby ensuring the reliability and accuracy of the film shaping.

[0041] Optionally, any two adjacent rows of limiting components are arranged staggered along the first horizontal direction.

[0042] For details, please refer to Figure 2In the illustrated embodiment, from top to bottom, the first, third, and fifth rows of odd-numbered position limiting components are arranged side by side, the second, fourth, and sixth rows of even-numbered position limiting components are arranged side by side, and the position limiting components adjacent to the first row, the second row, the third row, and the fourth row are arranged in a staggered manner. Among them, the position limiting components in the even-numbered rows are to the left of the position limiting components in the odd-numbered rows.

[0043] Continue to refer to Figure 2 When the first and second rows of limiting components cooperate to clamp the conductive cloth 1, the upper side of the conductive cloth 1 is supported by the first row of limiting components, and the lower side is supported by the second row of limiting components. Since the two rows of limiting components have different supporting positions, more positions on a conductive cloth 1 are limited. This is conducive to ensuring the limited stability of the conductive cloth 1 and further avoiding displacement or deformation of the membrane during the cutting and shaping process.

[0044] Optionally, a plurality of mounting holes are provided on the substrate 110, and any mounting hole is used to set a limiting column 121; the composite film positioning mechanism 100 also includes a plurality of elastic members 111, and an elastic member 111 is provided in any mounting hole, and one end of any elastic member 111 is connected to the mounting hole and the other end is connected to the limiting column 121.

[0045] The elastic member 111 may be made of elastic structures such as springs and spring sheets, or may be made of elastic materials such as rubber and plastic. The elastic member 111 has the characteristics of deformation upon force and recovery upon force release.

[0046] For details, please refer to Figure 3 In the illustrated embodiment, two rows of mounting holes are arranged on the substrate 110 in a direction perpendicular to the paper plane, and each row includes four mounting holes arranged at intervals in the left-right direction; the mounting holes are arranged in a one-to-one correspondence with the limiting columns 121, and an elastic member 111 is arranged in any mounting hole; the bottom end of the elastic member 111 is fixedly connected to the bottom of the mounting hole, and the top end is fixedly connected to the limiting column 121. When the limiting column 121 is subjected to force, the elastic member 111 is compressed, and the limiting column 121 can offset the pressure by entering and exiting the mounting hole to avoid rigid contact with the tool and the diaphragm.

[0047] Continue to refer to Figure 3 , the head of the limiting column 121 is protruding outside the mounting hole. When the composite film positioning mechanism 100 receives the film, the conductive cloth 1 is inserted into the limiting groove formed by the two rows of limiting columns 121. Ideally, the thickness of the conductive cloth 1 is not less than the groove height of the limiting groove, so that when the composite film positioning mechanism 100 receives the film, the conductive cloth 1 can fall onto the substrate 110, and the substrate 110 fully supports the film.

[0048] However, in actual production, factors such as material tolerance and equipment operation tolerance may cause the conductive cloth 1 to enter the limiting groove and fail to contact the substrate 110. At this time, the diaphragm is supported by the limiting pillars 121 and suspended on the substrate 110. In this case, if the cutting is performed directly by a punching tool, problems such as cutting position deviation and diaphragm deformation are likely to occur.

[0049] The elastic member 111 is provided so that the limiting column 121 can move elastically. When the diaphragm is supported by the limiting column 121 and suspended on the substrate 110, the punching tool can contact and press down the diaphragm. At this time, the limiting column 121 is compressed, and the pressure causes the elastic member 111 to be compressed and deformed, and the limiting column 121 is received in the mounting hole so that the diaphragm falls on the substrate 110. The diaphragm is supported by the substrate 110, which can ensure 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 member 111 is compressed and deformed, its elastic force can also act in the opposite direction on the diaphragm to ensure that the diaphragm is compressed between the tool and the substrate 110, further optimizing the shaping effect of the diaphragm.

[0050] In other embodiments, the head of the limiting column 121 for contacting the diaphragm can be made of elastic material, or the limiting column 121 can be provided with two elastically connected parts (one part is fixed on the substrate 110, and the other part is elastically connected to the fixed part through elastic parts such as springs). These methods can achieve elastic contact between the limiting column 121 and the diaphragm.

[0051] Optionally, the limiting column 121 is configured to be tapered, and the closer to the substrate 110 , the larger the outer diameter of the limiting column 121 .

[0052] For details, please refer to Figure 3 In the illustrated embodiment, the head of the limiting pillar 121 away from the substrate 110 is arranged in a frustum shape, and the outer diameter of the head of the limiting pillar 121 increases gradually from top to bottom. In this way, when the limiting groove formed by two rows of limiting pillars 121 is used to accommodate the conductive cloth 1, the top opening of the limiting groove is large, which can facilitate the entry of the conductive cloth 1. As the opening of the limiting groove gradually shrinks, the limiting groove can introduce the conductive cloth 1 into the bottom of the groove, so that the conductive cloth 1 is restricted between the limiting pillar 121 and the substrate 110.

[0053] Optionally, a plurality of limiting posts 121 are arranged in an array; along the second horizontal direction, the spacing between the limiting posts 121 is adjustable.

[0054] For details, please refer to Figure 2 In the illustrated embodiment, ten rows and eight columns of limiting posts 121 are provided on the substrate 110 , and along the first horizontal direction, any two adjacent columns of limiting posts 121 are arranged in a staggered manner.

[0055] Continue to refer to Figure 2, along the second horizontal direction, the first row and the second row of limiting components are brought closer to each other, and the width of the limiting groove formed by the two is reduced, so as to limit the conductive cloth 1 with a smaller width; the first row and the second row of limiting components are moved away from each other, and the width of the limiting groove formed by the two is increased, so as to limit the conductive cloth 1 with a larger width.

[0056] Similarly, by making the third and fourth rows of limiting components, the fifth and sixth rows of limiting components, etc., which are used to form the limiting grooves, closer to or farther away from each other, the width of the limiting grooves can be changed, so that the composite membrane positioning mechanism 100 can limit composite membrane diaphragms of different specifications.

[0057] Continue to refer to Figure 2 , along the second horizontal direction, the second row and the third row of limiting components, the fourth row and the fifth row of limiting components... and other two rows of limiting components that are not used to form the limiting grooves are close to or away from each other, and the limiting structure of the composite film positioning mechanism 100 can be adjusted accordingly according to the spacing between two adjacent conductive cloths 2 in the diaphragm to be positioned.

[0058] Therefore, the spacing between the limiting posts 121 and the limiting posts 121 in the second horizontal direction is adjustable, which can improve the applicability of the composite film positioning mechanism 100. Specifically, before the composite film positioning mechanism 100 receives films of different specifications, the relative position of each row of limiting posts 121 in the second horizontal direction is adjusted first, so that the readjusted limiting grooves can still accurately accommodate each conductive fabric 1.

[0059] In one embodiment, the limiting pillar 121 and the base plate 110 are connected by magnetic attraction.

[0060] For example, a magnet is provided in the substrate 110, and the limiting column 121 is made of metal material; at this time, the limiting column 121 is placed at a suitable position on the substrate 110, and the limiting column 121 can be fixed on the substrate 110 by magnetic attraction, and the relative positions of the limiting columns 121 and the limiting columns 121 meet the usage requirements.

[0061] For another example, the base plate 110 is provided with a plurality of mounting holes, and a suitable mounting hole is selected to install the limiting column 121, so that the relative positions of the limiting columns 121 and the limiting columns 121 can meet the use requirements.

[0062] For example, a plurality of slide grooves are provided on the base plate 110, any one of the slide grooves extends along the second horizontal direction, and a plurality of slide grooves are arranged at intervals along the first horizontal direction; a row of limit columns 121 are slidably set in a slide groove; after the limit column 121 is slid to the desired position, the limit column 121 is fixed by screwing, clamping, etc., so that the relative positions of the limit columns 121 and the limit columns 121 can meet the use requirements.

[0063] The present application does not limit the specific method of adjusting the position of the limiting column 121.

[0064] In a specific embodiment, the composite film positioning mechanism 100 provided in the present application also includes multiple groups of linkage components, any group of linkage components can be linked to a row of limit columns 121; the linkage components include: a connecting rod 151, a connecting rod 151 is connected between any two adjacent limit columns 121 in the same row, the connecting rod 151 is extended along the second horizontal direction, and the limit columns 121 are slidably set on the connecting rod 151; a guide sleeve 152, a guide sleeve 152 is slidably set on any connecting rod 151, and any guide sleeve 152 is between two adjacent limit columns 121; the limit columns 121 are pulled apart by the connecting rod 151, and when the two adjacent limit columns 121 move to the extreme positions at both ends of the connecting rod 151 between the two, the distance between the limit columns 121 is the farthest; the limit columns 121 are pushed closer by the connecting rod 151, and when the two adjacent limit columns 121 move to press against the guide sleeve 152 between the two, the distance between the limit columns 121 is the shortest.

[0065] For details, please refer to Figure 4 and Figure 5 In the illustrated embodiment, a plurality of rows of limiting posts 121 are provided on the base plate 110, and one row includes five limiting posts 121 spaced apart along the second horizontal direction. In one row of limiting posts 121, a connecting rod 151 is connected between any two adjacent limiting posts 121, and the limiting posts 121 are sleeved on the connecting rod 151 and can slide along the connecting rod 151; baffles 153 are provided at both ends of any connecting rod 151, and the baffles 153 can prevent the limiting posts 121 from sliding off the connecting rod 151. A guide sleeve 152 is sleeved on any connecting rod 151, and the guide sleeve 152 can also slide along the connecting rod 151.

[0066] Continue to refer to Figure 4 and Figure 5 The linkage assembly also includes a linkage drive 154. The linkage drive 154 can adopt a driving structure such as a cylinder or an electric cylinder that can drive the limit column 121 to translate along the second horizontal direction. In the illustrated embodiment, the first limit column 121 arranged on the left is fixedly arranged on the substrate 110 and will not move along the second horizontal direction. The other limit columns 121 are all slidably arranged on the substrate 110. The substrate 110 is also provided with a guide groove, a guide rail and a guide member. The other limit columns 121 are slidably arranged on the guide member and are restricted by the guide member and can only move along the second horizontal direction. The last limit column 121 arranged on the right is connected to the linkage drive 154 and can actively translate under the drive of the linkage drive 154.

[0067] Reference Figure 4When each limiting column 121 is located at the end of the connecting rod 151 and two adjacent limiting columns 121 are located at the two ends of the same connecting rod 151 , the distance between the limiting columns 121 is the largest.

[0068] Combined with reference Figure 5 , so that the linkage driving member 154 pushes the last limiting column 121 from right to left. Under the linkage of the connecting rod 151 and the limiting action of the guide sleeve 152, finally, each limiting column 121 abuts against the guide sleeve 152, and two adjacent limiting columns 121 abut against the same guide sleeve 152. At this time, the distance between the limiting columns 121 and the limiting columns 121 is the smallest.

[0069] Since the maximum distance is limited by the connecting rod 151 and the minimum distance is limited by the guide sleeve 152, in this embodiment, any row of limit posts 121 has two reliable preset distances through a set of linkage components, and the composite membrane positioning mechanism 100 can be used to limit membranes of two specifications.

[0070] By means of the linkage assembly, the spacing between two adjacent limiting grooves will not be changed while the spacing between one row of limiting posts 121 is changed.

[0071] In a specific embodiment, the shape punching die includes four blade dies 131 , the four blade dies 131 are arranged along the four sides of a square, and the limiting assembly is arranged in a frame formed by the four blade dies 131 .

[0072] For details, please refer to Figure 2 In the illustrated embodiment, four blade dies 131 are arranged end to end in a square shape.

[0073] Combined with reference Figure 3 The blade die 131 is a concave die with a chamfered surface inside, and the punching tool adopts a convex die with a blade end; when cutting and shaping, the punching tool can be inserted into the blade die 131, and the blade end is tangent to the chamfered surface.

[0074] More specifically, the size of the film is larger than the size of the square formed by the four blade dies 131. When the composite film positioning mechanism 100 supports the film, the projection of the film on the composite film positioning mechanism 100 can completely cover the square formed by the four blade dies 131. When cutting and shaping, the punching tool and the blade die 131 are made to correspond one to one. The punching tool is inserted into the blade die 131 to trim the four sides of the film, so that the size of the film is adjusted to the size of the square, and the size of the square is the size of the required finished film.

[0075] In other embodiments, the shape punching die also includes an arc corner punching die, and the arc corner punching die can cooperate with the punching tool to punch out rounded corners at the four corners of the diaphragm.

[0076] In a specific embodiment, the hole punching die includes: two rows of circular hole punches 141, the two rows of circular hole punches 141 are arranged at intervals along the second horizontal direction, and the limiting assembly is arranged between the two rows of circular hole punches 141; two vertical hole punches 142, the two vertical hole punches 142 are arranged at intervals along the first horizontal direction between the limiting assemblies.

[0077] For details, please refer to Figure 2 In the illustrated embodiment, four blade punches 131 form a square, in which two rows of round hole punches 141 are arranged, one row of round hole punches 141 is arranged near the upper side of the square, and the other row of round hole punches 141 is arranged near the lower side of the square. Any row includes four round hole punches 141 arranged at intervals in the left-right direction.

[0078] The circular hole punching die 141 is provided with a cylindrical hole, and correspondingly, the punching tool includes a cylindrical punching column for inserting into the circular hole punching die 141. When cutting and shaping, the cylindrical punching column can be inserted into the circular hole punching die 141, thereby flushing away the part of the diaphragm located on the circular hole punching die 141 and punching a circular hole on the diaphragm.

[0079] Continue to refer to Figure 2 Eight rows of limiting columns 121 are arranged in the frame formed by four blade punches 131. From left to right, a vertical hole punch 142 is arranged in the second and third rows of limiting columns 121, and another vertical hole punch 142 is arranged in the sixth and seventh rows of limiting columns 121. The two vertical hole punches 142 are arranged side by side in the left-right direction, and any vertical hole punch 142 is extended in the up-down direction.

[0080] Combined with reference Figure 3 The vertical hole punching die 142 is a concave die and is arranged in a long strip shape. Correspondingly, the punching tool includes a rectangular punching block for inserting into the vertical hole punching die 142. When cutting and shaping, the rectangular punching block can be inserted into the vertical hole punching die 142, thereby punching away the part of the diaphragm located on the vertical hole punching die 142 and punching out a long strip hole on the diaphragm.

[0081] In other implementations, the hole punching die may also be provided in various shapes such as a triangle and an arc, so as to punch holes of different shapes on the membrane to meet different membrane process requirements.

[0082] Optionally, the composite film positioning mechanism 100 provided in the present application further includes a limiting bar 160 , which is disposed on the substrate 110 and is used to limit the position of the composite film positioning mechanism 100 to receive the film.

[0083] As can be seen from the above, the size of the diaphragm is larger than the size of the square formed by the outer shape punching die. Therefore, although the composite film positioning mechanism 100 can limit the position of the conductive cloth 1 through the limit assembly, it cannot ensure that the diaphragm covers the outer shape punching die. If one side of the diaphragm does not completely cover the outer shape punching die, the cutter cannot cut the diaphragm on this side during cutting and shaping, which will inevitably make the final product fail to meet the process requirements.

[0084] Therefore, a limiting strip 160 is added to the substrate 110, and the limiting strip 160 is used to limit the edge of the diaphragm to ensure that the conductive cloth 1 on the diaphragm is confined in the limiting groove, and the side of the diaphragm is against the limiting strip 160, so that the diaphragm can be quickly and accurately confirmed to be placed in place.

[0085] Among them, four limiting bars 160 can be arranged on the composite film positioning mechanism 100, and the four limiting bars 160 are arranged at the four sides of the membrane. When the membrane is in place, the four limiting bars 160 can cooperate to limit the membrane therein.

[0086] Alternatively, two limit bars 160 can be provided on the composite membrane positioning mechanism 100, and the two limit bars 160 are arranged adjacent to each other, one limit bar 160 is used to limit the long side of the diaphragm, and the other limit bar 160 is used to limit the short side of the diaphragm; when the diaphragm is in place, one corner of the diaphragm is limited by the two limit bars 160. Since the diaphragm is square, when one corner of the diaphragm is limited, the diaphragm must be in a preset position.

[0087] The present application also provides a punching device, including the above-mentioned composite film positioning mechanism 100, and also includes: a material receiving table 210, the composite film positioning mechanism 100 is arranged on the material receiving table 210; a punching drive assembly 220, used to drive the material receiving table 210 to and from the loading and unloading station and the punching station; a punching tool 230, which is arranged at the punching station and is used to punch the film.

[0088] For details, please refer to Figure 6 In the illustrated embodiment, the punching device further includes a chassis, and the punching tool 230 is suspended in the chassis; the receiving platform 221 can enter and exit the chassis under the drive of the punching drive assembly 220. In this way, the chassis can not only hide and protect the punching tool 230, but also prevent the punching tool 230 from being exposed to the outside and posing a safety hazard.

[0089] The punching drive assembly 220 may be a cylinder, an electric cylinder, or other drive components. The punching tool 230 is provided corresponding to the shape punching die and the hole punching die, and the details can be referred to above, which will not be described here.

[0090] During punching, the punching drive component 220 drives the receiving table 221 to leave the chassis and receive the film at the loading and unloading station; after the film is placed in the composite film positioning mechanism 100, the punching drive component 220 drives the receiving table 221 to return to the chassis and receive the operation of the punching tool 230 at the punching station.

[0091] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
