Description

Technical Field

[0001] The present application relates to the technical field of electrical connection structures, and in particular to a method for manufacturing a flexible electrical connection sheet, a manufacturing device and a storage medium. Background Art

[0002] In the electronic product manufacturing industry, flexible electrical connectors are widely used in various scenarios that require flexible connection and signal transmission, such as flexible display screens, wearable devices, and automotive electronics, due to their excellent flexibility and conductivity. However, in the production process of flexible electrical connectors, insulation treatment is a crucial link, which is directly related to the electrical safety, durability, and overall performance of the product.

[0003] In the traditional manufacturing process of flexible electrical connectors, insulation treatment is mostly done manually by putting an insulating tube on the conductive connection. This method has significant technical problems: first, it is inefficient, the manual tube-putting process is cumbersome and time-consuming, and it is difficult to meet the needs of large-scale production; second, it is difficult to ensure accuracy, especially when dealing with the corners between the connection parts. Due to the small space and inconvenient operation, it is often difficult to accurately and completely insert the insulating tube. In addition, since the structure of the flexible electrical connector usually includes multiple connection parts in different directions or angles, the use of a single long insulating tube often cannot fit the contours of each connection part tightly. Especially at the corners, the insulating tube is prone to wrinkles or gaps, which not only reduces the insulation effect, but may also damage the insulation layer due to stress concentration, thereby affecting the reliability and service life of the product. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a method for manufacturing a flexible electrical connection sheet, a manufacturing device and a storage medium, which can improve the efficiency of the bushing and improve the insulation effect of the bushing.

[0005] In a first aspect, the present application provides a method for manufacturing a flexible electrical connection sheet, which is applied to a manufacturing device for the flexible electrical connection sheet, wherein the manufacturing device comprises: a die-cutting device, a hot pressing device and a sleeve device, wherein the sleeve device comprises a folding module and a combination module;

[0006] The production method comprises:

[0007] A plurality of soft copper sheets are stacked and fed into a die-cutting device, and the die-cutting device is controlled to cut the multiple layers of the soft copper sheets to obtain a first semi-finished product; wherein the first semi-finished product comprises a first connecting portion, a second connecting portion and a third connecting portion that are not on the same straight line, two ends of the second connecting portion are respectively connected to one end of the first connecting portion and one end of the third connecting portion, and the lengths of the first connecting portion and the third connecting portion are less than the length of the second connecting portion;

[0008] Sending the other ends of the first connecting portion and the third connecting portion in the first semi-finished product into the hot pressing device to hot-press the multiple layers of the soft copper sheets in the other ends of the first connecting portion and the third connecting portion into contact pins, thereby forming a second semi-finished product;

Subsequently, the first connecting part is folded by a folding module so that it is in the same direction as the second connecting part, so that the combination module can directly penetrate the first insulating tube from one end of the first connecting part and push it to the second connecting part along a straight path without complicated corner operations. Through the folding design, the sleeve path becomes a straight line, and the combination module can more accurately control the sleeve position and depth of the insulating tube, which not only improves the efficiency of the sleeve, but also reduces the difficulty of operation and the error rate. After the first insulating tube is sleeved, the folding module is controlled to restore the first connecting part to the initial position, and then the second insulating tube and the third insulating tube are sleeved on the first connecting part and the third connecting part respectively in the control combination module to form a third semi-finished product. Finally, the third semi-finished product is heat-shrunk to obtain a flexible electrical connector.

DETAILED DESCRIPTION

[0062] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0063] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0064] In the description of this application, if there is a description of first or second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0065] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0066] In the electronic product manufacturing industry, flexible electrical connectors are widely used in various scenarios that require flexible connection and signal transmission, such as flexible display screens, wearable devices, and automotive electronics, due to their excellent flexibility and conductivity. However, in the production process of flexible electrical connectors, insulation treatment is a crucial link, which is directly related to the electrical safety, durability, and overall performance of the product.

[0067] In the traditional manufacturing process of flexible electrical connectors, insulation treatment is mostly done manually by putting an insulating tube on the conductive connection. This method has significant technical problems: first, it is inefficient, the manual tube-putting process is cumbersome and time-consuming, and it is difficult to meet the needs of large-scale production; second, it is difficult to ensure accuracy, especially when dealing with the corners between the connection parts. Due to the small space and inconvenient operation, it is often difficult to accurately and completely insert the insulating tube. In addition, since the structure of the flexible electrical connector usually includes multiple connection parts in different directions or angles, the use of a single long insulating tube often cannot fit the contours of each connection part tightly. Especially at the corners, the insulating tube is prone to wrinkles or gaps, which not only reduces the insulation effect, but may also damage the insulation layer due to stress concentration, thereby affecting the reliability and service life of the product.

[0068] In summary, the existing insulation processing technology in the production of flexible electrical connecting sheets has deficiencies in efficiency and precision, especially when processing complex structures (such as multi-directional connecting parts and corners). Therefore, a more efficient and accurate insulation processing method is urgently needed to improve the production efficiency and product quality of flexible electrical connecting sheets.

[0069] Based on this, the present application provides a method for manufacturing a flexible electrical connecting sheet, a manufacturing device and a storage medium to solve the above-mentioned technical problems. The technical solutions provided by the present application are described in detail one by one below.

[0070] Reference Figures 1 to 8 and Fig.10 In the first aspect, the present application provides a method for manufacturing a flexible electrical connection sheet, which is applied to a manufacturing device for the flexible electrical connection sheet, the manufacturing device comprising: a die-cutting device, a hot pressing device and a sleeve device, the sleeve device comprising a folding module and a combination module. The manufacturing method may include but is not limited to the following methods:

[0071] Step S110: stacking a plurality of soft copper sheets and feeding them into a die-cutting device, and cutting the plurality of layers of soft copper sheets by controlling the die-cutting device to obtain a first semi-finished product; wherein the first semi-finished product comprises a first connecting portion, a second connecting portion and a third connecting portion which are not on the same straight line, two ends of the second connecting portion are respectively connected to one end of the first connecting portion and one end of the third connecting portion, and the lengths of the first connecting portion and the third connecting portion are less than the length of the second connecting portion;

[0072] Step S120: sending the other ends of the first connecting part and the third connecting part in the first semi-finished product into a hot pressing device to hot press the multi-layer soft copper sheets in the other ends of the first connecting part and the third connecting part to form contact pins, thereby forming a second semi-finished product;

[0073] Step S130: conveying the second semi-finished product to the sleeve device, and controlling the folding module to fold the first connecting portion so that the first connecting portion and the second connecting portion are in the same direction;

[0074] Step S140: controlling the combined module to insert the first insulating tube from the first connecting portion and sleeve the first insulating tube on the second connecting portion;

[0075] Step S150: controlling the folding module to restore the first connecting portion to the initial position, and controlling the combining module to sleeve the second insulating tube and the third insulating tube on the first connecting portion and the third connecting portion respectively, to form a third semi-finished product;

[0076] Step S160: subjecting the third semi-finished product to a heat shrinking treatment to obtain a flexible electrical connecting sheet.

[0077] For specific steps, please refer to Figures 2 to 9 ,in Figure 2 This is a schematic diagram of a second semi-finished product after die cutting and hot pressing after step S110 and step S120. Figure 3 and Figure 4 is a schematic diagram of folding the first connecting portion in step S130, Figure 5 This is a schematic diagram of inserting the first insulating tube through the combined module in step S140. Figure 6 This is a schematic diagram of the first insulating tube being inserted onto the second connecting portion in step S140. Figure 7 is a schematic diagram of restoring the first connecting portion to the initial position in step S150, Fig.10 It is a schematic diagram of respectively sleeve-mounting the first insulating tube and the second insulating tube on the first connecting portion and the second connecting portion in step S150.

[0078] In step S110 to step S160, a die-cutting device is used to cut a plurality of superimposed soft copper sheets into a first semi-finished product including a first connection part, a second connection part and a third connection part on non-colinear lines. Subsequently, the multi-layer soft copper sheets at the other end of the first connection part and the third connection part in the first semi-finished product are hot pressed together to form contact pins. Subsequently, the first connection part is folded by the folding module so that it is in the same direction as the second connection part, so that the combination module can directly penetrate the first insulating tube from one end of the first connection part and push it to the second connection part along a straight path without complicated corner operations. Through the folding design, the sleeve path becomes a straight line, and the combination module can more accurately control the sleeve position and depth of the insulating tube, which not only improves the efficiency of the sleeve, but also reduces the difficulty of operation and the error rate. After the first insulating tube is sleeved, the folding module is controlled to restore the first connection part to the initial position, and then the second insulating tube and the third insulating tube are sleeved on the first connection part and the third connection part respectively in the control combination module to form a third semi-finished product. Finally, the third semi-finished product is heat-shrunk to obtain a soft electrical connection sheet. In addition, the insulating tube in the present application can be segmented and the length and position of the insulating hose can be adjusted according to the actual size and shape of the connecting piece, thereby avoiding the problem that a single long insulating tube is difficult to fit a complex structure and improving the insulation effect.

[0079] It should be noted that in step S130, in addition to controlling the folding module to fold the first connection part, the folding module can also be controlled to fold the third connection part so that the third connection part and the second connection part are in the same direction. Therefore, in step S140, the first insulating tube is introduced from the third connection part and can be sleeved on the second connection part. Here, the first connection part can be the third connection part, that is, the steps performed on the first connection part are also applicable to the steps performed on the third connection part.

[0080] It is understandable that the sleeve device further includes an image recognition module; in step S130, the following steps may be included but not limited to:

[0081] Step S210: controlling the image recognition module to collect first image information of the second semi-finished product;

[0082] Step S220: determining a first folding line between the first connecting portion and the second connecting portion according to the first image information;

[0083] Step S230: According to the first folding line, controlling the folding module to fold the first connection portion along the first folding line toward the second connection portion;

[0084] Step S240: controlling the image recognition module again to collect second image information of the second semi-finished product;

[0085] Step S250: determining a second folding line on the first connecting portion according to the second image information;

[0086] Step S260: According to the second folding line, control the folding module to fold the first connection portion along the second folding line toward the outside of the second connection portion, so that the first connection portion and the second connection portion are in the same direction.

[0087] In step S210 to step S260, when the second semi-finished product is transferred to the sleeve device, the image recognition module is first started to capture the current state of the second semi-finished product and form the first image information. Subsequently, according to the first image information, the positions of the first connection part and the second connection part are identified by image processing technology, and according to the positional relationship between the two connection parts, the first folding line is calculated, and the first folding line indicates the path or direction in which the first connection part needs to be folded to approach the second connection part. The folding module is controlled to fold the first connection part toward the second connection part according to the calculated first folding line. After the initial folding, the image recognition module is started again to collect the second image information of the folded second semi-finished product, and the second folding line that needs to be further folded on the first connection part is determined by analyzing the second image information. The folding module is controlled to fold the first connection part further toward the outside of the second connection part according to the second folding line until the two are in the same direction, thereby ensuring the consistency of the first connection part and the second connection part in subsequent operations, and facilitating the subsequent sleeve processing.

[0088] In the above steps, by introducing the image recognition module, the automatic recognition and analysis of the state of the second semi-finished product is realized, thereby reducing manual intervention and improving the automation of the production line. And by folding, the first connection part and the second connection part are in the same direction, so the combination module can directly insert the first insulating tube from one end of the first connection part and push it to the second connection part along a straight path without complicated corner operations. Through the folding design, the sleeve path becomes a straight line, and the combination module can more accurately control the insertion position and depth of the insulating tube, which not only improves the efficiency of the sleeve, but also reduces the difficulty of operation and the error rate.

[0089] Reference Figure 3 It is understandable that step S220 may include but is not limited to the following steps:

[0090] Step S310: determining first edge information of the second semi-finished product according to the first image information;

[0091] Step S320: determining a first intersection point and a second intersection point of two edges of the first connecting portion and the second connecting portion according to the first edge information;

[0092] Step S330: determining a first folding line between the first connecting portion and the second connecting portion according to the first intersection point and the second intersection point.

[0093] In step S310 to step S330, the image recognition module first processes the first image information and uses the edge detection algorithm to identify the first edge information in the second semi-finished product. Through edge detection, the system can extract key edge information such as contour lines and dividing lines in the second semi-finished product, especially the edges related to the first connecting part and the second connecting part. Through image processing techniques such as comparison and matching, the system can determine the first intersection point and the second intersection point between the two edges of the first connecting part and the second connecting part, thereby obtaining the first folding path. The first folding line is the shortest path or the optimal path from the first intersection point to the second intersection point. It indicates the direction and degree to which the first connecting part needs to be folded so that it is in the same direction as the second connecting part. In the above method, the folding operation can be automatically completed by simply placing the semi-finished product in the specified position and starting the equipment without complicated settings and adjustments.

[0094] Reference Figure 4 It is understandable that step S250 may include but is not limited to the following steps:

[0095] Step S410: determining second edge information of the second semi-finished product after the first connecting portion is folded along the first folding line according to the second image information;

[0096] Step S420: determining a third intersection point on the first fold line and a first sideline on the first connection portion according to the second edge information; wherein the third intersection point is an end point of the first fold line close to the third connection portion, and the first sideline is a sideline on the first connection portion corresponding to an end point of the first fold line away from the third connection portion;

[0097] Step S430: determining a second folding line located at the first connecting portion according to the third intersection point and the first sideline; wherein the second folding line is a line segment passing through the third intersection point and perpendicular to the first sideline.

[0098] In step S410 to step S430, in order to enable the first insulating tube to be completely sleeved on the position of the second connection part, after the first connection part is folded along the first folding line, the system starts the image recognition module again to collect the second image information at this time, and extracts the second edge information of the second semi-finished product after the folding from the second image information through image processing techniques such as edge detection. Subsequently, the third intersection point and the first edge line are obtained by analyzing the second edge information, wherein the third intersection point is the same point as the first intersection point mentioned above. The second folding line is determined to further adjust the position or shape of the first connection part so that the first connection part and the second connection part are still maintained in the same direction, and the first connection part can also cover the least area in the second connection part.

[0099] Reference Figure 8 and Fig.10 It can be understood that the second insulating tube includes a first insulating tube and a second insulating tube, and the third insulating tube includes a third insulating tube and a fourth insulating tube. In step S150, the following steps may be included but are not limited to:

[0100] Step S510: controlling the folding module to restore the first connection part to the initial position, and controlling the combining module to sleeve the first insulator tube and the third insulator tube on the first connection part and the third connection part respectively; wherein one end of the first connection part and the third connection part away from the second connection part is exposed from the second insulating tube and the third insulating tube respectively;

[0101] Step S520: Control the combination module to respectively sleeve the second insulator tube and the fourth insulator tube on the corner between the first connection part and the second connection part and the corner between the third connection part and the second connection part to form a third semi-finished product; wherein the two ends of the second insulator tube are respectively sleeved on the first insulating tube and the first insulator tube, and the two ends of the fourth insulator tube are respectively sleeved on the first insulating tube and the third insulator tube.

[0102] In step S510 to step S520, the second insulating tube is divided into two sections, namely the first insulating tube and the second insulating tube, and the third insulating tube includes two sections, namely the third insulating tube and the fourth insulating tube. The insulating tube is sheathed in sections, and the length and position of the insulating hose can be adjusted according to the actual size and shape of the connecting piece, thereby avoiding the problem that a single long insulating tube is difficult to fit a complex structure, and improving the insulation effect. In addition, the control combination module sheaths the second insulating tube and the fourth insulating tube at the corner between the first connecting part and the second connecting part, and at the corner between the third connecting part and the second connecting part, respectively, and the two ends of the second insulating tube are sheathed on the first insulating tube and the first insulating tube, respectively, and the two ends of the fourth insulating tube are sheathed on the first insulating tube and the third insulating tube, respectively. The second insulating tube and the fourth insulating tube are sheathed on the existing insulating tube to form a stable support system, which helps to resist external mechanical stress and environmental changes and prevent the connection from loosening or deformation.

[0103] Reference Fig. 9 It is understandable that the manufacturing device also includes a cutting device, and before step S520, it also includes but is not limited to the following steps:

[0104] Step S610: respectively obtaining the widths of the first connection portion, the second connection portion, and the third connection portion;

[0105] Step S620: determining a first arc radius between the first connection portion and the second connection portion according to the maximum value of the width of the first connection portion and the width of the second connection portion, and determining a second arc radius between the second connection portion and the third connection portion according to the width of the second connection portion and the width of the third connection portion;

[0106] Step S630: According to the first arc radius, with the inner intersection of the first connection part and the second connection part as the center of the circle, control the cutting device to perform arc cutting on the corner of the first connection part and the second connection part; and, according to the second arc radius, with the inner intersection of the second connection part and the third connection part as the center of the circle, control the cutting device to perform arc cutting on the corner of the second connection part and the third connection part.

[0107] In step S610 to step S630, because the overall radial width of the intersection of the first connection part and the second connection part is large, it is easy to cause unnecessary expansion of the second insulator tube. In addition, the sharp corner at the intersection of the first connection part and the second connection part is also easy to puncture the second insulator tube, thereby reducing the life of the flexible electrical connection piece. Therefore, in the above steps, the first arc radius at the corner between the first connection part and the second connection part is determined according to the maximum value of the width of the first connection part and the second connection part. The wider connection part may require a larger radius when bending to avoid material stress concentration or damage. Similarly, the second arc radius at the corner between the second connection part and the third connection part is determined according to the width of the second connection part and the third connection part. The intersection of the inner side of the first connection part and the second connection part is determined as the center of the circle for cutting the first arc, and the intersection of the inner side of the second connection part and the third connection part is determined as the center of the circle for cutting the second arc. According to the calculated first arc radius and the position of the center of the circle, the cutting device is controlled to perform precise arc cutting on the corners of the first connection part and the second connection part. Similarly, according to the second arc radius and the position of the center of the circle, arc cutting is performed on the corners of the second connection part and the third connection part. It should be noted that the cutting device can be a laser cutting machine, a robotic arm with a cutting head, etc., which is not limited in the present application. By cutting an arc transition that meets the width of the material, the stress concentration phenomenon caused by the right-angle or sharp-angle transition of the connection part during the bending process can be significantly reduced, thereby improving the overall durability and reliability of the flexible electrical connection piece. The arc transition makes the connection part smoother when bending, reduces the bending resistance caused by right angles or sharp angles, and makes the flexible electrical connection piece more flexible and easy to install in application scenarios with complex shapes.

[0108] It is understandable that the manufacturing equipment also includes a heating device, and the first insulating tube, the second insulating tube, and the third insulating tube are heat shrink tubes; the heat shrink tube is a special polyolefin heat shrink tube. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is composited with hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, and wear resistance, and the inner layer has the advantages of low melting point, waterproof sealing, and high adhesion. In this regard, in step S160, the following steps may be included but not limited to:

[0109] Step S710: Control the heating device to blow out a constant temperature vortex hot air flow at the top and bottom of the third semi-finished product; wherein a certain inclination angle is formed between the constant temperature vortex hot air flow and the third semi-finished product;

[0110] Step S720: Blowing a constant temperature vortex hot air flow to the third semi-finished product for a preset first time, so that the first insulating tube, the second insulating tube, and the third insulating tube are respectively tightened with the surface of the soft copper sheet to form a soft electrical connecting sheet.

[0111] In step S710 to step S720, the heating device is controlled to blow out a constant temperature vortex hot air flow at the top and bottom of the third semi-finished product. This airflow is constant temperature, and its temperature is precisely controlled to avoid overheating and damaging the material. At the same time, the vortex design helps the airflow to cover the entire heating area more evenly, thereby improving the heating efficiency. A certain inclination angle is formed between this airflow and the third semi-finished product, so that the constant temperature vortex hot air flow can better penetrate into the tiny gap between the insulating tube and the soft copper sheet, thereby heating more evenly and promoting the shrinkage of the insulating tube. The heating device blows out a constant temperature vortex hot air flow to the third semi-finished product for a preset first time. The setting of the first time is based on the material, thickness and required shrinkage degree of the insulating tube to ensure that the insulating tube can fully and evenly shrink and fit closely with the surface of the soft copper sheet. After the above heating process, the first insulating tube, the second insulating tube, and the third insulating tube are tightened with the surface of the soft copper sheet respectively, forming a soft electrical connection sheet with a compact structure and good insulation performance.

[0112] It is understandable that step S110 may include but is not limited to the following steps:

[0113] Step S810: stacking a plurality of soft copper sheets together, and stacking a layer of protective metal sheet on the topmost layer and the bottommost layer of the plurality of soft copper sheets respectively, to form a raw material;

[0114] Step S820: Feed the raw material into the die-cutting device, and control the die-cutting device to cut the raw material according to a preset shape, and control the cutting depth of the die-cutting device to cut off the protective metal sheet on the second connecting part, the first connecting part, and the protective metal sheet on the partial area of ​​the third connecting part close to the second connecting part, to form a first semi-finished product.

[0115] In step S810 to step S820, the hardness of the protective metal sheet is greater than the hardness of the soft copper sheet. Before die-cutting, a protective metal sheet is stacked on the top and bottom layers of the multiple soft copper sheets. The main function of these protective metal sheets is to prevent the edges or specific areas of the soft copper sheets from being mechanically damaged or deformed during the subsequent die-cutting process. Subsequently, the cutting depth of the die-cutting device is also controlled to cut off the protective metal sheet on the second connection part, the first connection part, and the protective metal sheet on the partial area of ​​the third connection part close to the second connection part, in order to retain most of the protective metal sheet on the first connection part and the third connection part, because in subsequent use, the ends of the first connection part and the third connection part need to be used as two connecting pins of the flexible electrical connection piece, so the protective metal sheet can increase the hardness of the pin position at the first connection part and the third connection part, and improve the stability of the flexible electrical connection piece when in use.

[0116] Reference Fig.11It is understandable that the manufacturing device also includes a bending device and a punching device; after step S150, it may also include but not limited to the following steps:

[0117] Step S810: controlling the bending device to bend the portion of the first connecting portion exposed from the second insulating tube and the portion of the third connecting portion exposed from the third insulating tube to form a first contact portion and a second contact portion respectively;

[0118] Step S820: Controlling the punching device to punch holes on the first contact portion and the second contact portion respectively, thereby forming a first fixing hole on the first contact portion and forming a second fixing hole on the second contact portion.

[0119] In step S810 to step S820, the first connection part and the third connection part are bent by a bending device to form a first contact part and a second contact part. Such a design can greatly increase the stability and reliability of the connection with the external electrical device. The bent contact part can be more firmly fixed to the connection point of the external electrical device, reducing the problem of poor contact or falling off caused by vibration or external force. Holes are punched on the first contact part and the second contact part to form a first fixing hole and a second fixing hole respectively. This step facilitates the subsequent fixed installation. By using screws, rivets or other fasteners to pass through these fixing holes, the flexible electrical connector can be easily fixed to the external electrical device, which simplifies the installation process and improves the installation efficiency.

[0121] In the manufacturing equipment, a plurality of superimposed soft copper sheets are cut into a first semi-finished product including a first connection part, a second connection part and a third connection part on non-colinear lines by a die-cutting device, and then the multi-layer soft copper sheets at the other end of the first connection part and the third connection part in the first semi-finished product are hot pressed together to form a contact pin. Then, the first connection part is folded by a folding module so that it is in the same direction as the second connection part, so that the combination module can directly penetrate the first insulating tube from one end of the first connection part and push it to the second connection part along a straight path without complicated corner operations. Through the folding design, the sleeve path becomes a straight line, and the combination module can more accurately control the sleeve position and depth of the insulating tube, which not only improves the efficiency of the sleeve, but also reduces the difficulty of operation and the error rate. After the first insulating tube is sleeved, the folding module is controlled to restore the first connection part to the initial position, and then the second insulating tube and the third insulating tube are sleeved on the first connection part and the third connection part respectively by controlling the combination module to form a third semi-finished product. Finally, the third semi-finished product is heat-shrunk to obtain a soft electrical connection sheet. In addition, the insulating tube in the present application can adjust the length and position of the insulating hose according to the actual size and shape of the connecting piece by means of segmented sleeves, thereby avoiding the problem that a single long insulating tube is difficult to fit a complex structure, thereby improving the insulation effect.
