[0046] Please see Figures 1 to 3 This application first provides an embodiment of an automatic folding device for U-shaped card products, which includes:

[0047] The assembly includes a frame assembly 01 and U-shaped card feeding assembly 02, U-shaped card folding assembly 03, U-shaped card transfer assembly 04, connecting card feeding assembly 05, connecting card folding assembly 06, connecting card transfer assembly 07, and assembly assembly 08, all mounted on the frame assembly 01. The U-shaped card feeding assembly 02 feeds unformed U-shaped cards from the hopper 09 to the U-shaped card folding assembly 03. The U-shaped card folding assembly 03 folds the unformed U-shaped cards into U-shaped cards. The U-shaped card transfer assembly 04 is used for... The folded U-shaped card is transferred from the U-shaped card folding assembly 03 to the installation station 10.

The connecting card folding assembly 06 is used to fold the connecting card in half to form a connecting card. The connecting card transfer assembly 07 is used to transfer the folded connecting card from the connecting card folding assembly 06 to the installation station 10. The assembly assembly 08 is used to assemble the connecting card on the installation station 10 with the U-shaped card.

[0048] The following is a detailed description of each component of the automatic folding device for U-shaped cards:

[0049] Rack assembly 01: Rack assembly 01 is the supporting structure of the entire equipment, providing the basic framework and stability required by the equipment.

[0050] U-shaped card feeding assembly 02: This assembly is responsible for feeding unformed U-shaped cards from the hopper 09 to the U-shaped card folding assembly 03. This may include a conveyor system, gripping device, or other suitable motion module to ensure that the raw materials can be smoothly introduced into the folding process.

[0051] U-shaped card folding assembly 03: U-shaped card folding assembly 03 is a key process unit used to precisely fold unformed U-shaped cards into U-shaped cards according to a predetermined folding method. This can be achieved through a dedicated folding mold, transmission device, and folding control system.

[0052] U-shaped card transfer assembly 04: The task of this transfer assembly is to transfer the folded U-shaped cards from the U-shaped card folding assembly 03 to the installation station 10. This may include a conveyor belt, robotic arm, or other suitable transfer device to ensure the product remains stable during transfer.

[0053] Connector Card Feeding Component 05: Connector Card Feeding Component 05 is responsible for feeding unformed connector cards to Connector Card Folding Component 06. This feeding component can be similar to the U-shaped card feeding component 02, which can also be achieved through a conveyor system, gripping device, or some motion module.

[0054] Connector Card Folding Component 06: This component is used to precisely fold unformed connector cards to form connector cards. This may include a dedicated folding mold, control system, motion module, etc., to ensure the folding quality of the connector cards.

[0055] Connector card transfer assembly 07: This assembly is responsible for transferring the folded connector cards from the connector card folding assembly 06 to the installation station 10. Similar to the U-shaped card transfer assembly 04, it may include a conveyor belt, a robotic arm, a motion module, and other devices.

[0056] Assembly Component 08: Assembly Component 08 is the final process unit of the equipment, and its task is to assemble the connecting clips and U-shaped clips on the installation station 10. This involves precision alignment devices, clamping devices, and other assembly tools.

[0057] Workflow:

[0058] Unformed U-shaped cards and connecting cards are fed from their respective hoppers 09 to the corresponding feeding components.

[0059] The U-shaped card feeding component 02 conveys the U-shaped card to the U-shaped card folding component 03, enabling automatic folding.

[0060] The folded U-shaped card is transferred to the installation station 10 via the U-shaped card transfer component 04.

[0061] At the same time, the connector card feeding component 05 transmits the connector card to the connector card folding component 06, completing the automatic folding.

[0062] The folded connector is transferred to the installation station 10 via the connector transfer component 07.

[0063] Assembly component 08 precisely assembles the connecting card and U-shaped card on the installation station 10.

[0064] The equipment provided in this application is used to produce U-shaped card products. These U-shaped card products are assembled from U-shaped cards and connecting cards. The assembly method for the U-shaped cards and connecting cards can be through slot installation. For example, the U-shaped card has a slot, and the connecting card is vertically inserted into the slot to achieve mutual fixation. One connecting card can connect multiple U-shaped cards simultaneously, such as 2, 3, 4, 5, or 6. The specific number can be determined according to the specifications of the actual product and is not limited here.

[0065] Advantages of this embodiment:

[0066] Fully automated operation: The equipment achieves fully automated operation of the entire production process through the coordinated operation of its various components, reducing the cost of manual operation.

[0067] Efficient folding and transfer: The design of each component enables efficient folding and transfer processes, improving production efficiency.

[0068] Consistent quality: The equipment ensures the consistency and stability of the folding quality of the U-shaped cards and connecting cards through a dedicated folding mold and control system.

[0069] Integration and assembly: The equipment efficiently assembles the connecting card and the U-shaped card together through assembly component 08, ensuring the high quality of the final product.

[0070] In this application, the connector card transfer component 07 is used to move the folded connector card from the connector card folding component 06 to the installation station 10 for further installation by the assembly component 08. The connector card transfer component 07 can be implemented by a robot, conveyor belt or some motion module, and the assembly component 08 can be implemented by an automated module such as a cylinder or robot. In practice, the connector card transfer component 07 and the assembly component 08 can be separate modules or integrated into one module.

[0071] Here are some possible implementation methods:

[0072] The connector card transfer assembly 07 is a key component of this automatic folding device. Its task is to transfer the folded connector cards from the connector card folding assembly 06 to the installation station 10, so that the connector cards and U-shaped cards can be assembled subsequently by the assembly assembly 08. In practical applications, the connector card transfer module can be implemented using different technologies, among which possible implementations include:

[0073] Robotic Arm: The connector card transfer module can be equipped with a flexible robotic arm, which uses its gripping device to accurately move the folded connector card to the installation station 10. The robotic arm can have multiple degrees of freedom and can operate flexibly in three-dimensional space.

[0074] Conveyor Belt: The connector card transfer module can also use a conveyor belt system to smoothly transport the folded connector cards to the installation station 10. This method is suitable for scenarios requiring efficient and continuous transportation and can work in conjunction with other modules.

[0075] Motion Module: The connector card transfer component 07 can employ motion modules such as slide rails and guide rails to move the connector card to the installation station 10 by adjusting its position and orientation. This method is suitable for scenarios with limited space or requiring a specific motion trajectory.

[0076] In practical applications, the connector card transfer component 07 can be equipped with an automated control system that can sense the position and status of the connector card in real time and ensure that the connector card is not damaged during the transfer process and maintains stable transportation.

[0077] Assembly Component 08:

[0078] Assembly component 08 is another key module in this automatic folding device, its task being to assemble the connecting card and the U-shaped card. In practical applications, assembly component 08 can be implemented using various different technologies, among which possible implementations include:

[0079] Cylinder: Assembly component 08 can be equipped with a cylinder system. Through the extension and retraction of the cylinder, precise alignment and assembly of the connecting clip and the U-shaped clip are achieved. The cylinder system can provide greater force to ensure the stability of the assembly.

[0080] Robotic Arm: Similar to the connector card transfer module, assembly component 08 can also employ a robotic arm system. The robotic arm's gripping device precisely assembles the connector card and U-shaped card together. The robotic arm offers high flexibility during the assembly process.

[0081] See Figure 4 , 5In addition to the above, this application provides a preferred embodiment in which the connector card transfer assembly 07 and the assembly assembly 08 are integrated to a certain extent. In this embodiment, the connector card transfer assembly 07 includes a connector card transfer motion module 071, and the assembly assembly 08 includes an assembly cylinder module 081. The assembly cylinder module 081 is disposed on the slide of the connector card transfer motion module 071. The cylinder shaft of the assembly cylinder module 081 is provided with a clamping structure 082 and a rotating structure 083. The connector card transfer motion module 071 drives the clamping structure 082 to move to the connector card folding assembly 06. The clamping structure 082 clamps the connector card. The clamping structure 082 is connected to the cylinder shaft through the rotating structure 083. The rotating structure 083 drives the clamping structure 082 to rotate, thereby transferring the connector card from the connector card folding assembly 06 to the installation station 10.

[0082] In this embodiment, the connector card transfer motion module 071 is the core component of the integrated connector card transfer assembly 07. It may include components such as a slide table, guide rail system, and drive device, used to move and position the connector card within the device. This module can achieve accurate positioning and movement through an automated control system.

[0083] The assembly cylinder module 081 is a key component of the integrated assembly assembly 08. This module drives the movement of the clamping structure 082 through the telescopic movement of the cylinder shaft, thereby achieving the clamping and transfer of the connecting card.

[0084] The rotating structure 083 can be rotated via a gear or belt system by setting a rotating shaft. This shaft can be driven by a motor or a manual device. Through the engagement and rotation of the gears, the clamping structure can rotate around the shaft. This is a simple and reliable mechanical implementation. The main function of the rotating structure 083 is to drive the clamping structure to rotate.

[0085] Work process:

[0086] The connector card transfer motion module 071 operates first, moving the clamping structure 082 to the connector card folding assembly 06. The clamping structure 082 may include grippers, clamping arms, etc., to form a stable clamp on the connector card.

[0087] The clamping structure 082 is connected to the cylinder shaft via a rotating structure. Once the connector is clamped, the rotating structure 083 is activated, causing the clamping structure 082 to rotate. The purpose of this step is to transfer the connector from the connector folding assembly 06 to the installation station 10.

[0088] Through the action of the rotating structure 083, the clamping structure 082 transfers the connector card from the connector card folding assembly 06 to the installation station 10. The automated design of this process ensures the stability and accuracy of the connector card during transfer.

[0089] At installation station 10, the cylinder module 081 begins operation, extending and retracting the cylinder shaft and adjusting the position of the clamping structure 082 to ensure proper alignment of the connecting clip and the U-shaped clip. The clamping structure 082 holds the connecting clip to ensure secure installation. The entire process can be monitored and adjusted in real time by the automated control system.

[0090] In this embodiment, the integrated connector card transfer component 07 and assembly component 08 form a unified design, making the equipment structure more compact, occupying less space, and improving the overall efficiency of the production line. Through the precise positioning of the connector card transfer motion module and the rotation of the clamping structure 082, the connector card can be efficiently and stably transferred from the folding component to the installation station 10, reducing downtime in the production line. Precise adjustment of the assembly cylinder module 081 ensures high-quality assembly of the connector card and the U-shaped card, improving the stability and consistency of the final product. The automated control system enables intelligent monitoring and adjustment of the entire process, ensuring efficient and stable production operation of the equipment.

[0091] In this embodiment, the rotation of the clamping structure 082 driven by the rotating structure 083 can be within a range of 180 degrees. In this way, connecting card folding assemblies 06 can be provided on both sides of the installation station 10. The clamping structure 082 is located above the installation station 10. The clamping structure 082 can clamp and transfer the connecting card on the left connecting card folding assembly 06 to the installation station 10 by rotation, and it can also clamp and transfer the connecting card on the right connecting card folding assembly 06 to the installation station 10 by rotation. The rotation angle between the clamping structure 082 and the connecting card folding assembly 06 from the installation station 10 can be 90 degrees. Through this structure, the clamping structure 082 can rotate periodically and intermittently according to a certain pattern, realizing the alternating feeding of the connecting card folding assemblies 06 on both sides to the installation station 10 for installation.

[0092] In this application, the U-shaped card folding component 03 is used to fold an unformed U-shaped card into a U-shaped card. The unformed U-shaped card is a flat card shape, and the folded U-shaped card presents a "U" shape. In practice, the U-shaped card folding component 03 can have multiple implementations. The following are some possible implementations:

[0093] Contouring folding mold:

[0094] Using a specially designed contour-folding die, the flat card can be folded according to the shape of the U-shaped card. The contour-folding die ensures that the folded U-shaped card is accurate in shape and can control the card to prevent it from springing back after going over 90 degrees during the folding process.

[0095] Roller or roller pressing:

[0096] By using a set of rollers or rollers, a flat card can be gradually rolled into a U-shape during the folding process. This method may require the coordinated work of multiple rollers or rollers to ensure accurate folding and shape control of the card.

[0097] Bending and forming machinery:

[0098] Using bending forming machinery, flat cards are bent into a U-shape by applying bending force at specific locations.

[0099] Cylinder and clamping system:

[0100] The cylinder and clamping system can apply appropriate force to the U-shaped card during the folding process to help complete the folding.

[0101] See Figure 7 , 8 9, 10 and Figure 11 ;

[0102] This application provides a preferred embodiment of a U-shaped card folding assembly 03, which includes:

[0103] The U-shaped card folding assembly 03 includes an upper mold 031, a lower mold 032, an upper lifting cylinder 033, a lower lifting cylinder 034, and a clamping cylinder 035. The upper mold 031 is connected to the cylinder shaft of the upper lifting cylinder 033, and the upper lifting cylinder 033 drives the upper mold 031 to move up and down. The lower mold 032 is connected to the cylinder shaft of the lower lifting cylinder 034, and the clamping cylinder 035 is connected to the cylinder shaft of the lower lifting cylinder 034, and the lower lifting cylinder 034 drives the lower mold 032 to move up and down. During folding, the clamping cylinder 035 drives the lower mold 032 to clamp the two sides of the U-shaped card, and the upper mold 031 cooperates with the lower mold 032 to compress the U-shaped card to form a U-shape.

[0104] The following is a detailed description of embodiment 03 of the U-shaped card folding component:

[0105] Upper mold 031: The upper mold 031 is one of the key components of the U-shaped card folding assembly 03. It is connected to the cylinder shaft of the upper lifting cylinder 033, and its up-and-down movement is achieved through the movement of the upper lifting cylinder 033. The shape and size design of the upper mold 031 are matched to the folding requirements of the U-shaped card.

[0106] Lifting cylinder 033: The lifting cylinder 033 is a power device used to control the up and down movement of the upper mold 031. Through the cylinder shaft connection of the lifting cylinder 033, the lifting cylinder 033 can accurately control the position of the upper mold 031, ensuring the precision of the folding process.

[0107] Lower mold 032: The lower mold 032 is another key part of the U-shaped card folding assembly 03. It is connected to the cylinder shaft of the lower lifting cylinder 034, and its up-and-down movement is achieved through the movement of the lower lifting cylinder 034. The shape and size design of the lower mold 032 are matched to the folding requirements of the U-shaped card.

[0108] Lower lifting cylinder 034: The lower lifting cylinder 034 is a power device used to control the up and down movement of the lower mold 032. Through the cylinder shaft connection of the lower lifting cylinder 034, the lower lifting cylinder 034 can accurately control the position of the lower mold 032, ensuring the precision of the folding process.

[0109] Clamping cylinder 035: Clamping cylinder 035 is a key component used to clamp the U-shaped card during folding. Clamping cylinder 035 is connected to the cylinder shaft of the lower lifting cylinder 034. Through the movement of the lower lifting cylinder 034, clamping cylinder 035 drives the lower mold 032 to clamp both sides of the U-shaped card, so as to better complete the folding work and make the U-shaped card fully folded between the upper mold 031 and the lower mold 032.

[0110] Work process:

[0111] Before folding begins, the U-shaped card folding assembly 03 is in its initial position. The upper mold 031 and the lower mold 032 are in their predetermined positions, and the clamping cylinder 035 is in the released state.

[0112] First, the lifting cylinder 033 is activated, causing the upper mold 031 to move downwards, providing space for the folding of the U-shaped card. After the upper mold 031 moves downwards, it can just fix the card between the upper mold 031 and the lower mold 032. Then, the lower mold 032 moves upwards to complete the folding of the card.

[0113] The clamping cylinder 035 is activated, clamping both sides of the U-shaped card. This action ensures that the U-shaped card remains stably clamped during folding.

[0114] The lower lifting cylinder 034 is activated, causing the lower mold 032 to move upward. Under the combined action of the upper mold 031 and the lower mold 032, the U-shaped card gradually folds to form a U-shape.

[0115] When the upper mold 031 and the lower mold 032 come together completely, the folding process is complete. The U-shaped card takes on a "U" shape, and the clamping cylinder 035 releases its grip, ready to transfer the folded U-shaped card to the next workstation or assembly station.

[0116] Furthermore, in order to better complete the folding of the U-shaped card, the upper mold 031 can be provided with a slanted surface, so that the folding angle of the U-shaped card exceeds 90 degrees when folding, so as to leave a certain margin for the card's rebound.

[0117] Specifically, the bottom of the upper mold 031 is provided with a mold bottom surface 0311, and the two sides are provided with mold inclined surfaces 0312. The upper ends of the mold inclined surfaces 0312 tend to move closer to each other, and the lower ends tend to move further apart from each other.

[0118] In this improved embodiment, the design of the upper mold 031 is further optimized to better complete the folding of the U-shaped card and reserve a certain amount of leeway for the card's rebound. Specifically, the bottom of the upper mold 031 is provided with a mold bottom surface 0311, and the two sides are provided with mold inclined surfaces 0312. The design of the mold inclined surfaces 0312 has a tendency for their upper ends to approach each other and a tendency for their lower ends to move away from each other.

[0119] In this embodiment, the bottom of the upper mold 031 is provided with a flat mold bottom surface, which is used to support the bottom of the U-shaped card to form a flat bottom edge during the folding process.

[0120] The inclined surfaces 0312 of the mold are located on both sides of the upper mold 031, with their upper ends tending to move closer together and their lower ends tending to move further apart. The upper ends of the inclined surfaces tend to move closer together, causing the upper sides of the U-shaped card to gradually approach each other during folding, creating an effect where the flip angle exceeds 90 degrees. This design helps to provide allowance for the card's rebound during folding.

[0121] The lower ends of the mold slope 0312 tend to move away from each other. This design helps to ensure that the bottom two sides of the U-shaped clip can be stably kept at a certain distance after folding, forming a U-shape.

[0122] The shape of the lower mold 032 can match that of the upper mold 031. Specifically, the lower mold 032 includes sub-molds 0320 arranged symmetrically on both sides. The bottom of the sub-mold 0320 is provided with a pressing bottom surface 0321, and the inner side is provided with a pressing inclined surface 0322. The pressing inclined surface 0322 is parallel to the mold inclined surface 0312, and the pressing bottom surface 0321 is parallel to the mold bottom surface 0311.

[0123] In this improved embodiment, the design of the lower mold 032 matches that of the upper mold 031, including sub-molds 0320 arranged symmetrically on both sides. Each sub-mold 0320 has a pressing bottom surface on its bottom and a pressing slope on its inner side.

[0124] In this embodiment, the lower mold 032 consists of two sub-molds 0320 arranged symmetrically on both sides to ensure that the U-shaped card can be subjected to force evenly during the folding process.

[0125] Each sub-mold 0320 has a flat, pressed bottom surface to support the bottom of the U-shaped card, forming a flat bottom edge during folding.

[0126] Each sub-mold 0320 has a pressing slope on its inner side, which is parallel to the mold slope of the upper mold 031. This design helps guide the upper part of the U-shaped card to gradually move closer together during folding, forming a flipping angle.

[0127] The pressing bottom surface is parallel to the bottom surface of the upper mold 031, and the pressing inclined surface is parallel to the inclined surface of the upper mold 031. This design ensures the mutual matching of the upper mold 031 and the lower mold 032, so that the U-shaped card can be stably stressed during the folding process and ensures that the U-shaped card formed after folding is accurate in shape.

[0128] The equipment provided in this application is used to produce U-shaped card products. These U-shaped card products are assembled from U-shaped cards and connecting cards. The assembly method for the U-shaped cards and connecting cards can be through slot installation. For example, the U-shaped cards have slots, and the connecting cards are vertically inserted into the slots to achieve mutual fixation. One connecting card can connect multiple U-shaped cards simultaneously, such as 2, 3, 4, 5, or 6. When the number of U-shaped cards exceeds two, multiple U-shaped card folding components 03 can be provided simultaneously. Folding can be achieved simultaneously through multiple U-shaped card folding components 03, which further enables synchronized loading and unloading operations. For example:

[0129] See Figure 11 , 12 13, 14, 15, and 16, N U-shaped card folding assemblies 03 are installed on one side of the installation station 10, where N is an integer greater than or equal to 2. One or all of the U-shaped card transfer assembly 04 or the U-shaped card loading assembly 02 adopt the following structure:

[0130] The structure includes: a U-shaped card transfer motion module 021, a U-shaped card feeding cylinder 022, a U-shaped card feeding groove plate 023, and N feeding claws 024. The U-shaped card feeding groove plate 023 has a U-shaped card feeding groove 025. The N feeding claws 024 are all connected to the cylinder shaft of the U-shaped card feeding cylinder 022. The U-shaped card feeding cylinder 022 is fixed on the slide table of the U-shaped card transfer motion module 021. When loading or unloading, the U-shaped card feeding cylinder 022 drives the feeding claws 024 to extend from the U-shaped card feeding groove 025 and hook the U-shaped card. The U-shaped card transfer motion module 021 drives the feeding claws 024 to push the U-shaped card to load or unload.

[0131] In another optional embodiment, the U-shaped card feeding assembly 02 may also be provided with an auxiliary pressure roller 12. The auxiliary pressure roller 12 may be provided on both sides of the U-shaped card feeding groove 025 and located above the U-shaped card feeding groove plate 023, with a certain gap between it and the U-shaped card feeding groove plate 023. The function of the auxiliary pressure roller 12 is to assist in feeding the U-shaped card. When the U-shaped card moves on the feeding groove plate for feeding, the U-shaped card passes through the gap between the auxiliary pressure roller 12 and the U-shaped card feeding groove plate 023.

[0132] In this optional embodiment, the auxiliary pressure rollers 12 are positioned on both sides of the U-shaped card feeding groove 025, above the U-shaped card feeding groove plate 023, to provide auxiliary support for feeding the U-shaped cards. This helps ensure the stability and smoothness of the U-shaped cards during the feeding process.

[0133] In the aforementioned embodiments, the U-shaped card product is assembled from U-shaped cards and connecting cards using a slot installation method. The U-shaped card has a slot, and the connecting card is vertically inserted into the slot to secure them together. One connecting card can connect to multiple U-shaped cards simultaneously, with the number of connections being 2, 3, 4, 5, 6, etc. Furthermore, to improve production efficiency, multiple U-shaped card folding components 03 can be configured to enable synchronized loading and unloading operations.

[0134] In this embodiment, a U-shaped card feeding groove 025 is provided on the U-shaped card feeding groove plate 023, and N feeding claws 024 are connected to the cylinder shaft of the U-shaped card feeding cylinder 022. Each feeding claw 024 is responsible for hooking and fixing a U-shaped card.

[0135] During the loading or unloading process, the U-shaped card feeding cylinder 022 and the U-shaped card transfer motion module 021 work together to enable the feeding claw hook 024 to extend from the U-shaped card feeding slot 025 and hook the U-shaped card. Finally, the U-shaped card transfer motion module 021 pushes the U-shaped card to load or unload. The following are the detailed steps of this process:

[0136] Initial position:

[0137] The U-shaped card folding assembly 03 is in the ready state, and the U-shaped card feeding cylinder 022 and the U-shaped card transfer motion module 021 are both in the initial position.

[0138] Feeding process:

[0139] When material needs to be fed, the U-shaped card feeding cylinder 022 is activated.

[0140] The material feeding claw 024 extends out from the U-shaped material feeding groove 025.

[0141] After the material feeding claw hook 024 successfully hooks the U-shaped card, the U-shaped card feeding cylinder 022 maintains this state.

[0142] U-shaped card transfer:

[0143] At the same time, the U-shaped card transfer motion module 021 is activated.

[0144] The drive claw hook 024 carries the U-shaped card and begins to move, moving the U-shaped card folding assembly 03 out along the feeding groove.

[0145] Push it to the loading position:

[0146] The U-shaped card transfer motion module 021 pushes the U-shaped card carried by the feeding claw hook 024 to the feeding position.

[0147] In this position, the U-shaped card can be used for subsequent processes, such as assembly after folding.

[0148] Similarly, the U-shaped card transfer assembly 04 can also use the same structure, and its unloading process can be as follows:

[0149] Material feeding process:

[0150] When it is necessary to unload materials, first ensure that the loading process has been completed.

[0151] The U-shaped card feeding cylinder 022 is activated again, causing the feeding claw hook 024 to hook the U-shaped card that has been folded.

[0152] The U-shaped card transfer motion module 021 is activated, and continues to push the U-shaped card carried by the material feeding claw hook 024 to the installation station 10.

[0153] At this position, the U-shaped card can be removed or used for the next step of processing or assembly.

[0154] This embodiment mentions that multiple U-shaped card folding components 03 can be set up to perform multiple U-shaped card loading and unloading operations at the same time, thereby further improving the efficiency of the entire production line. Furthermore, since one U-shaped card feeding cylinder 022 is equipped with N feeding claws 024 simultaneously, meaning the number of feeding claws 024 corresponds to the number of U-shaped card folding components 03, multiple U-shaped card folding components 03 can be loaded and unloaded using a single U-shaped card feeding cylinder 022, greatly improving the compactness and coordination of the structure.

[0155] In this application, the function of the connecting card folding component 06 is to fold the connecting card in half to form a connecting card. There are multiple ways to implement the structure of the connecting card folding component 06. The following are some possible implementations:

[0156] Cylinder-based folding mechanism:

[0157] This implementation may include one or more cylinders, whose extension and retraction movements fold the connecting card in half. The cylinder's movement can be precisely controlled by a control system to ensure the accuracy and stability of the folding process.

[0158] Folding mechanism based on swing arm:

[0159] The connector card folding assembly 06 can be designed with a swing arm structure, which allows the connector card to be folded in half by swinging the arm.

[0160] Roller-based folding mechanism:

[0161] Using a roller or pulley system, the connection card can be folded by adjusting the position and trajectory of the rollers. This design may require a sophisticated trajectory control system to ensure the accuracy of the folding.

[0162] Folding mechanism based on contour mold:

[0163] Using a specially designed contour-following mold, the connector can be folded precisely according to its shape. This mold design ensures that the connector does not deform or get damaged during the folding process.

[0164] Folding mechanism based on servo motor:

[0165] By utilizing a servo motor and related transmission system, the connection card can be precisely folded by controlling the rotation of the motor.

[0166] See Figure 17 , 19 20 and 21, this application provides a preferred embodiment of a connector card folding assembly 06, which includes:

[0167] An X-axis folding cylinder 061, a Y-axis folding cylinder 062, and an L-shaped folding plate 063 are connected. The X-axis folding cylinder 061 is connected to the cylinder shaft of the Y-axis folding cylinder 062, and the L-shaped folding plate 063 is connected to the cylinder shaft of the X-axis folding cylinder 061. The X-axis folding cylinder 061 and the Y-axis folding cylinder 062 cooperate to drive the L-shaped folding plate 063 to move, so as to fold the connecting card in half.

[0168] This preferred embodiment employs a combination of an X-axis folding cylinder 061, a Y-axis folding cylinder 062, and an L-shaped folding plate 063. Through their coordinated action, the connecting card is folded in half. The following is a detailed description of this embodiment:

[0169] X-axis folding cylinder 061 and Y-axis folding cylinder 062:

[0170] The X-axis folding cylinder 061 and the Y-axis folding cylinder 062 can be controlled independently, moving in the horizontal and vertical directions respectively. This design provides precise control over the folding process of the connector card in multiple directions.

[0171] L-shaped folding plate 063:

[0172] The L-shaped folding plate 063 is connected to the cylinder shaft of the X-axis folding cylinder 061. The design of the L-shaped folding plate 063 allows it to fold under the control of the X and Y axes, thereby achieving the folding of the connecting card. The "L" shape of this folding plate enables continuous actions such as "hooking," "pushing," and "pressing" on the connecting card, thus forming a fold.

[0173] Collaborative working mechanism:

[0174] The X-axis folding cylinder 061 and the Y-axis folding cylinder 062 work together, connecting the L-shaped folding plate 063 via their cylinder shafts. The X-axis folding cylinder 061 controls the horizontal folding of the connecting card, while the Y-axis folding cylinder 062 controls the vertical folding. Their coordinated movement enables omnidirectional folding of the connecting card.

[0175] By adjusting the movement trajectory and speed of the X-axis folding cylinder 061 and the Y-axis folding cylinder 062, precise control of the folding process can be achieved. This design makes the folding process of the connector card more controllable and adaptable to connector cards of different sizes and shapes.

[0176] The connector card feeding component 05 in this application is used to feed unformed connector cards from the hopper 09 to the connector card folding component 06. The connector card feeding component 05 can be implemented through various automated structures.

[0177] Pneumatic suction cup feeding system:

[0178] Using a pneumatic suction cup feeding system, the connector card is picked up from the hopper 09 and moved to the connector card folding assembly 06 by the suction cup.

[0179] Conveyor belt feeding mechanism:

[0180] Using a conveyor belt, connector cards are transported from hopper 09 along a specific path to connector card folding assembly 06. The speed and direction of the conveyor belt can be precisely adjusted by the control system to meet the requirements of the production line.

[0181] Roller conveyor system:

[0182] A roller conveyor system is used to transport the connection card to the connection card folding assembly 06 via a series of rollers.

[0183] Robotic arm loading system:

[0184] Using a robotic arm, grippers, suction cups, and other tools, connector cards are picked up from the hopper 09 and placed into the connector card folding assembly 06. The robotic arm system is highly flexible and precise, and is suitable for connector cards of different shapes and sizes.

[0185] See Figure 17 , 18 19 and 20; This application also provides a preferred embodiment of a connector card feeding assembly 05, wherein the structure of the connector card feeding assembly 05 in this embodiment can be implemented by a combination of a cylinder and a motion module, and this embodiment includes:

[0186] The system includes a connector card transfer motion module 051, a connector card feeding cylinder 052, a connector card feeding groove plate 053, and a feeding fork 054. The feeding fork 054 is connected to the cylinder shaft of the connector card feeding cylinder 052. The connector card feeding cylinder 052 is fixed on the slide table of the connector card transfer motion module 051. The connector card feeding groove plate 053 is provided with a connector card feeding groove 055. The connector card is placed on the connector card feeding groove plate 053. During feeding, the connector card feeding cylinder 052 drives the end of the feeding fork 054 to pass through the connector card feeding groove 055. The connector card transfer motion module 051 drives the feeding fork 054 to push the connector card to the connector card folding assembly 06.

[0187] The preferred embodiment of the connector card feeding assembly 05 is described in detail below:

[0188] In this preferred embodiment, the connector card feeding assembly 05 adopts a combination of cylinder and motion module to achieve automatic feeding of connector cards.

[0189] Connector card transfer motion module 051:

[0190] The connector card transfer motion module 051 is a motion control component that may include elements such as guide rails and sliders to ensure accurate transfer of the connector card. This motion module can be an electrically driven lead screw module. The main function of the connector card transfer module is to transfer the connector card to the connector card folding assembly 06 for folding.

[0191] Connecting Card Feeding Cylinder 052:

[0192] The connecting card feeding cylinder 052 is a pneumatic component connected to the feeding fork 054 via a cylinder shaft. This cylinder controls the movement of the feeding fork 054, thereby realizing the feeding action of the connecting card.

[0193] Connecting card feeding slot plate 053:

[0194] The connector card feeding slot plate 053 is a platform that holds connector cards and has connector card feeding slots 055 on it. Connector cards are placed on the feeding slot plate during loading to facilitate subsequent feeding operations.

[0195] Feeding fork 054:

[0196] The feeding fork 054 is the end tool of the connecting card feeding cylinder 052, and can be a fork-shaped structure. During feeding, the end of the feeding fork 054 passes through the connecting card feeding groove 055, clamps the connecting card, and pushes it to the connecting card folding assembly 06.

[0197] Material loading process:

[0198] When the feeding process begins, the connector card feeding cylinder 052 starts working, causing the end of the feeding fork 054 to extend out of the connector card feeding slot 055. The connector card transfer motion module 051 then starts working, pushing the connector card on the feeding fork 054 to the position of the connector card folding assembly 06.

[0199] Through the coordinated operation of the connector card feeding cylinder 052 and the connector card transfer motion module 051, this embodiment achieves a stable and efficient feeding process for connector cards. This structural design is flexible and controllable, suitable for connector cards of different sizes and shapes, and improves production efficiency.

[0200] In another optional embodiment, the connector card feeding assembly 05 may also be provided with an auxiliary pressure roller 12. The auxiliary pressure roller 12 may be provided on both sides of the connector card feeding groove 055 and located above the connector card feeding groove plate 053, with a certain gap between them. The function of the auxiliary pressure roller 12 is to assist in feeding the connector card. When the connector card moves on the feeding groove plate for feeding, the connector card passes through the gap between the auxiliary pressure roller 12 and the connector card feeding groove plate 053.

[0201] In this optional embodiment, the auxiliary pressure rollers 12 are positioned on both sides of the connector card feeding slot 055, above the connector card feeding slot plate 053, to provide auxiliary support for feeding the connector cards. This helps ensure the stability and smoothness of the connector card feeding process.

[0202] In this application, the installation station 10 is set on the frame assembly 01. The installation station 10 is used to carry the folded connecting card and U-shaped card and to provide space for assembly. In one embodiment, the U-shaped card and connecting card are unloaded at different positions of each folding assembly. Therefore, the U-shaped card and connecting card need to be moved to the same position before assembly.

[0203] Based on this, please refer to Figures 22 to 24This application provides a preferred embodiment of an installation station 10. In this embodiment, the installation station 10 is provided with an installation slot plate 101, and an installation slot 102 is provided on the installation slot plate. Below the installation slot plate, a U-shaped card pushing motion module 103, a double-headed pushing motion module 104, and a pushing gripper 105 are provided. The double-headed pushing motion module is provided with two slides, and the pushing gripper 105 is provided on each of the two slides. The double-headed pushing motion module 104 is located on the slide of the U-shaped card pushing motion module 103. The pushing gripper 105 protrudes from the installation slot 102. The double-headed pushing motion module 104 drives the pushing gripper 105 on the two slides to clamp the U-shaped card on the installation station 10. The U-shaped card pushing motion module 103 drives the pushing gripper 105 to move, so that the U-shaped card is transported to the assembly component 08.

[0204] In this preferred embodiment, the installation station 10 is designed to move the folded connector and U-shaped card to the same position for assembly. The following is a detailed description of this embodiment:

[0205] Mounting slot 101:

[0206] The mounting plate 101 is set on the mounting station 10 as a platform to support the assembled parts. The mounting plate has a mounting slot 102 for moving the U-shaped clip.

[0207] U-shaped card pusher motion module 103:

[0208] The U-shaped card pushing motion module 103 is a module for controlling the movement of the U-shaped card, and may include an electrically driven guide rail and a slide table. The module is designed to allow the U-shaped card to push material at the mounting station 10.

[0209] Dual-head pusher motion module 104:

[0210] The dual-head pusher motion module 104 includes two slides, each equipped with a pusher gripper 105. The purpose of this module is to grip the U-shaped card, ensuring it remains in a stable position and stable during the pusher motion.

[0211] Pusher gripper 105:

[0212] The pusher gripper 105 is a mechanical gripper used to hold the U-shaped card, and is set on the slide of the double-head pusher motion module 104. These grippers can extend out of the mounting slot plate 101 to hold the U-shaped card.

[0213] Material pushing operation process:

[0214] At the start of the feeding process, the dual-head feeding motion module 104 starts working, causing the feeding gripper 105 to clamp the U-shaped card. Then, the U-shaped card feeding motion module 103 works, pushing the U-shaped card to the position of the assembly component 08.

[0215] U-shaped clamps for holding and transporting:

[0216] The pusher jaws 105 on the two slides of the dual-head pusher motion module 104 hold the U-shaped card to ensure its stability. Then, the U-shaped card pusher motion module 103 drives the pusher jaws 105 and the U-shaped card to move together, transporting the U-shaped card to the assembly component 08.

[0217] Through this design, the embodiment of installation station 10 enables the U-shaped cards to be pushed from different positions to the same assembly position, ensuring that the U-shaped cards and connecting cards can be assembled smoothly. This structural design aims to improve assembly efficiency, ensure assembly accuracy, and adapt to changes in the position of different folding components.

[0218] It is worth noting that the structure provided in the above embodiments, in addition to moving the U-shaped card to the position of the assembly component 08, is also applicable to scenarios where multiple U-shaped cards are assembled. For example, when multiple U-shaped cards cut from the U-shaped card folding component 03 are placed on the installation station 10, the pusher gripper 105 is driven to move by the double-head pusher motion module 104, which can close and clamp all the U-shaped cards on the installation station 10 together. Then, the pusher gripper 105 and the U-shaped card are driven to move together by the U-shaped card pusher motion module 103, which transports the U-shaped card to the assembly component 08. In this way, when the assembly component 08 assembles the connecting card later, it can directly assemble the connecting card with all the U-shaped cards. Therefore, this structure can realize the closing and movement of the U-shaped cards at the same time.

[0219] Based on the above embodiments, it may further include a gripper drive cylinder 106, which is disposed on the slide of the dual-head pusher motion module 104. The pusher gripper 105 is fixed on the cylinder shaft of the gripper drive cylinder 106, and the gripper drive cylinder 106 drives the pusher gripper 105 to extend out of the mounting groove 102.

[0220] Based on the above embodiments, the further introduction of the gripper drive cylinder 106 is an optimized design. This design provides more precise and controllable gripper movements, enhancing the flexibility and efficiency of the feeding process.

[0221] The gripper drive cylinder 106 is mounted on the slide of the double-headed pusher motion module 104, serving as the power source for pushing the pusher gripper 105. This cylinder design makes the gripper's movement more precise and controllable.

[0222] The function of the gripper drive cylinder 106 is to control the pusher gripper 105 to extend out of the mounting slot 102. By regulating the air pressure of the cylinder, the gripper can be precisely extended, ensuring accurate clamping of the U-shaped card. After the U-shaped card is moved to the position of the assembly component 08, the gripper drive cylinder 106 can drive the pusher gripper 105 to retract, and the U-shaped card pusher motion module 103 resets to prepare for the next round of action.

[0223] See Figure 23 and 24 In an optional embodiment, the installation station 10 is provided with an installation and fixing assembly 11. The installation and fixing assembly 11 includes a fixing cylinder 111 disposed on both sides of the installation station 10 and a fixing part 112 connected to the cylinder shaft of the fixing cylinder 111. The end of the fixing part is provided with a trapezoidal part 113. During installation, the fixing cylinder 111 drives the fixing part 112 to move, so that the narrower end of the trapezoidal part 113 is embedded in the U-shaped clip to fix the U-shaped clip.

[0224] In this optional embodiment, a mounting and fixing assembly 11 is introduced, which is designed to secure the U-shaped clip more firmly and reliably through the structure of the fixing cylinder 111 and the trapezoidal portion 113.

[0225] In this embodiment, the fixing cylinders 111 are arranged on both sides of the installation station 10. When the connecting card is assembled onto the U-shaped card, the fixing cylinders 111 on both sides move, driving the movement of the fixing part 112, so that the trapezoidal part 113 can be embedded in the U-shaped card, thus fixing the U-shaped card. This fixing method is more secure than the traditional clamping, which helps to ensure the stability of the U-shaped card during the assembly process.

[0226] The trapezoidal part 113's structure allows for a tighter fit into the U-shaped clip during installation, enhancing its secure hold. This design helps prevent the U-shaped clip from shifting or loosening during assembly.

[0227] By embedding the trapezoidal part 113 into the U-shaped card, a firm fixation is formed for the U-shaped card, ensuring that the U-shaped card will not cause assembly errors or quality problems due to loosening in subsequent assembly stages.

[0228] See Figure 24 and Figure 15 In an optional embodiment, a U-shaped card positioning assembly 13 is provided on the installation station 10. The U-shaped card positioning assembly 13 includes positioning cylinders 131 disposed on both sides of the installation groove, and positioning strips 132 connected to the cylinder shafts of the positioning cylinders 131. The positioning cylinders 131 drive the positioning strips 132 to move, thereby aligning and positioning the U-shaped cards on the installation station 10.

[0229] In this embodiment, a U-shaped card positioning component 13 is introduced. The positioning cylinders 131 on both sides drive the positioning strip 132 to move, which can position the U-shaped card on the installation station 10 to a precise position, so that the U-shaped card pushing motion module can move the U-shaped card to the position of the assembly component 08.

[0230] In this optional embodiment, a U-shaped card positioning component 13 is introduced to ensure that the U-shaped card on the installation station 10 can be accurately and precisely positioned at the designated location.

[0231] In this embodiment, positioning cylinders 131 are disposed on both sides of the mounting groove. The position of positioning strip 132 can be controlled by the movement of the cylinders. Positioning strip 132 is connected to the cylinder shaft of positioning cylinder 131. When positioning cylinder 131 is driven, positioning strip 132 moves accordingly. This structure allows for bilateral positioning of the U-shaped card, ensuring that the U-shaped card can be accurately placed on the mounting station 10.

[0232] The presence of the U-shaped card positioning component 13 provides an accurate starting point for the U-shaped card pushing motion module 103. Once the U-shaped card is positioned correctly, the U-shaped card pushing motion module 103 can push it to the assembly component 08 to complete the entire assembly process. By introducing the U-shaped card positioning component 13, the accuracy of the entire assembly process is improved, ensuring that the U-shaped card can be accurately assembled with the connecting card, avoiding assembly deviations caused by inaccurate positioning.

[0233] Based on this embodiment, it further includes a linear guide rail 133, a guide block 134, and a connecting frame 135. The positioning strip 132 is connected to the guide block 134 through the connecting frame 135, and the guide block 134 slides linearly through the linear guide rail 133.

[0234] In this further embodiment, the U-shaped card positioning assembly 13 incorporates a linear guide rail 133, a guide block 134, and a connecting frame 135 to further improve the accuracy and stability of the positioning.

[0235] The linear guide 133 is a mechanical element for linear motion, introduced to provide linear movement of the positioning plate 132 in the horizontal direction. This guide design ensures smooth and accurate movement.

[0236] The guide block 134 slides linearly via the linear guide rail 133, a design that allows the guide block 134 to slide stably in the horizontal direction. This plays a crucial role in the accuracy and stability of the positioning strip 132.

[0237] The positioning strip 132 is connected to the guide block 134 via a connecting bracket 135, which serves as both a connector and support throughout the positioning process. This structure ensures that the positioning strip 132 remains stable during movement and responds accurately to the control of the positioning cylinder. The addition of the linear guide rail 133 and the connecting bracket 135 enhances the overall structural stability. This is crucial for maintaining the accuracy and reliability of the positioning components during production line operation.

[0238] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
