[0002] Stamped terminals are metal electronic components processed by precision stamping machines. They are commonly used in connectors, wire harnesses, and other products. They are characterized by their compact structure and high precision requirements. Automatic receiving devices are auxiliary equipment used in conjunction with stamping machines. They are used to receive the stamped terminals and complete the automated process of sorting, counting, and transferring them to storage containers.

[0003] Existing automatic terminal receiving devices are prone to damage due to contact between terminals during receiving. In addition, the receiving tray cannot be quickly disassembled and installed after receiving, which affects receiving efficiency. Summary of the Invention

[0004] The technical problem this invention aims to solve is that contact friction damage easily occurs during the terminal winding process, and the low efficiency of disassembling and assembling the take-up tray affects continuous winding.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An automatic take-up device for stamped terminals is proposed in this utility model, comprising a base and a support plate vertically mounted on the base. A winding structure is horizontally arranged on the support plate, and two sets of auxiliary guide rollers and paper roll rollers are also arranged on one side of the support plate. The winding structure includes a mounting plate horizontally arranged in the middle of the support plate, a turntable rotatably mounted on the mounting plate, a rotary motor mounted on the other side wall of the mounting plate, and the motor's output shaft connected to the turntable. Two sets of winding assemblies are symmetrically arranged on the turntable.

Two sets of buffer sleeves are symmetrically arranged on the mounting seat, and a U-shaped frame is also included. A pressing roller rotates inside the U-shaped frame. Two sets of sliding columns are provided on the other side of the U-shaped frame, and the other end of the sliding column is slidably disposed in the buffer sleeve. Buffer springs are sleeved on the buffer sleeves and sliding columns. The two ends of the buffer springs are respectively connected to the side wall of the mounting seat and the U-shaped frame. A pressure sensor is also provided between the side wall of the mounting seat and the U-shaped frame.

[0008] Preferred technical solution 3: The support plate is also provided with a vision inspection module, which includes an industrial camera and a light source.

[0011] The present invention provides an automatic receiving device for stamped terminals, and the beneficial effects achieved by adopting the above structure are as follows: (1) By setting the paper roll roller to synchronously feed the isolation paper with the terminal, physical isolation between layers is achieved during the terminal winding process, which solves the problem of friction damage caused by direct contact between the terminals from the root. At the same time, an auxiliary pressing structure is provided. By utilizing the adaptive characteristics of the buffer spring and the dynamic pressure adjustment function of the electric telescopic rod, a constant pressing force can be maintained according to the change of winding diameter, avoiding deviation and wrinkles during terminal winding, further ensuring the integrity and shape accuracy of the terminal surface, and significantly improving the qualification rate of the finished terminal product. (2) The dual-set winding assembly is symmetrically designed and can be used with a rotary table driven by a rotary motor to achieve alternating winding, which effectively avoids downtime caused by changing the take-up tray of a single winding assembly and ensures continuous winding operation; the take-up tray is quickly positioned by positioning pins and positioning holes, and can be disassembled without tools by combining with threaded caps. Compared with the traditional bolt fixing or snap-fit ​​structure, the disassembly and assembly time of the take-up tray is greatly shortened, the equipment operation efficiency is improved, and it is suitable for the high-speed production rhythm of stamping processing. (3) The device integrates a vision inspection module, which can capture terminal images in real time to achieve accurate counting and detection of defects such as missing corners and deformation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0016] Example 1 like Figures 1-4As shown, the technical solution adopted by this utility model is as follows: An automatic take-up device for stamped terminals includes a base 1 and a support plate 2 vertically arranged on the base 1. A winding structure 3 is horizontally arranged on the support plate 2. Two sets of auxiliary guide rollers 4 and paper roll rollers 5 are also arranged on one side of the support plate 2. The paper roll rollers 5 are wound with isolation paper. The isolation paper and the terminals enter the winding structure 3 simultaneously to achieve isolation between terminals and avoid friction damage during the winding process. The winding structure 3 includes a mounting plate 6 horizontally arranged in the middle of the support plate 2. A turntable 7 is rotatably arranged on the mounting plate 6. A rotary motor 8 is arranged on the other side wall of the mounting plate 6 and the motor's output shaft is connected to the turntable 7. Two sets of winding components are symmetrically arranged on the turntable 7, which can be wound alternately to avoid machine stoppage. Four sets of moving wheels are evenly distributed at the four corners of the bottom of the base 1. The moving wheels have a self-locking function, which makes it easy to move to the side of the stamping machine for fixing.

[0017] like Figure 1 As shown, the winding assembly includes a motor frame 9 mounted on a turntable 7. A turntable 10 rotates on one side of the motor frame 9, and a mounting shaft 11 is mounted on the turntable 10. A winding motor 12 is mounted on the motor frame 9, and the motor's power output shaft is connected to the turntable 10. A winding reel 13 is detachably mounted on the mounting shaft 11. A positioning post is mounted on one side of the turntable 10, and a positioning hole corresponding to the positioning post is mounted on the winding reel 13. The other end of the mounting shaft 11 is provided with an internal thread. The assembly also includes a cover 14 that is threadedly connected to the mounting shaft 11. The cover 14 is threadedly connected to the mounting shaft 11 and can be axially locked after tightening. No tools are required for disassembly and assembly, and the winding reel 13 is easy and quick to disassemble and install.

[0018] Example 2 Based on Example 1, such as Figure 4 As shown, in order to ensure stable winding of the material and release paper during the winding process, an auxiliary pressing structure is also provided on the support plate 2. The auxiliary pressing structure includes a pressing support plate 15, an electric telescopic rod 16 at the bottom of the pressing support plate 15, and a mounting base 17 at the free end of the electric telescopic rod 16. Two sets of buffer sleeves 18 are symmetrically arranged on the mounting base 17. It also includes a U-shaped frame 19, in which a pressing roller 20 rotates. Two sets of sliding columns 21 are provided on the other side of the U-shaped frame 19, and the other end of the sliding column 21 is slidably disposed on the buffer sleeve 18. Inside, a buffer spring 22 is fitted on the buffer sleeve 18 and the slide column 21. The two ends of the buffer spring 22 are connected to the side wall of the mounting base 17 and the U-shaped frame 19, respectively. A pressure sensor is also installed between the side wall of the mounting base 17 and the U-shaped frame 19 to detect the holding force. During operation, the electric telescopic rod 16 drives the holding roller 20 to press down. The buffer spring 22 can adapt to the thickness changes of the terminal and the release paper to maintain constant pressure and avoid deviation or wrinkling. As the diameter increases after winding, the position of the holding roller 20 is adjusted by the electric telescopic rod 16 to achieve stable holding force.

[0019] The support plate 2 is equipped with a vision inspection module 23, which includes an industrial camera and a light source. The industrial camera is a Hikvision MV-CA013-20GM model with a resolution of 12 megapixels and a frame rate of ≥30fps. It is fixed by an adjustable bracket with an adjustment angle of ±30°, and the center of the lens is at the same height as the axis of the auxiliary guide roller 4. A strip LED light source is set 100-120mm below the lens. The light source is fixed to the support plate 2 by a bracket, and the light shines perpendicularly on the terminal surface. The industrial camera captures images of the terminals passing through the auxiliary guide roller 4, extracts terminal features, and performs counting. At the same time, it can detect whether there are defects such as missing corners or deformation of the terminals. The detection results are fed back to the controller 24 in real time. The side wall of the support plate 2 is also equipped with a controller 24. The rotary motor 8, the winding motor 12, the electric telescopic rod 16, and the vision inspection module 23 are all electrically connected to the controller 24. The controller 24 is also equipped with a touch screen for setting parameters such as winding length, counting threshold, and status display.

[0020] How to use the automatic stamping terminal receiving device Device positioning and fixing Push the self-locking movable wheel at the bottom of the base 1 to move the device to the side of the terminal output end of the stamping machine, ensuring that the winding structure 3 is aligned with the terminal output path of the stamping machine; lock the self-locking mechanism of the movable wheel to prevent the device from shifting during operation.

[0021] Installation of release paper and reel The release paper is pulled out from the paper roll 5, and the terminal output direction of the punching machine passes around the two sets of auxiliary guide rollers 4 in sequence. Finally, the release paper and the free end of the terminal material are pulled to the winding reel 13 of one of the winding components and wound and fixed. Align the positioning hole of the take-up reel 13 with the positioning post on the turntable 10, and fit the take-up reel 13 along the mounting shaft 11; take the cover 14 and screw it into the internal thread of the mounting shaft 11, and manually tighten it until the take-up reel 13 has no axial looseness and no tools are needed to complete the installation of one set of take-up reels; repeat the above operation for the other set of take-up assemblies to ensure that both sets of take-up reels are in the ready-to-work state.

[0022] Parameter setting and component inspection Start the controller 24 and enter the parameter setting interface through the matching touch screen: set the winding length threshold and the counting threshold, and confirm the parameters of the vision detection module 23; Synchronous startup operation The device automatically activates the take-up mode via the touchscreen of controller 24, and then automatically links with the stamping machine. After the stamping machine begins outputting terminals, controller 24 drives the take-up motor 12 of one of the take-up components to operate. Simultaneously, the electric telescopic rod 16 drives the pressure roller 20 to press down until the pressure sensor detects the target pressing force, completing the start-up. An industrial camera continuously captures images of the terminals passing through the auxiliary guide roller 4, extracting features such as terminal edges and holes, automatically counting the terminals, and displaying the cumulative number in real time on the controller's touchscreen. If defects such as missing corners, deformation, or surface scratches are detected in the terminals, the controller immediately issues an audible and visual alarm and pauses the take-up motor 12. After the operator investigates and resolves the cause of the defect, the take-up can be restarted via the touchscreen.

[0023] During the winding process, as the diameter of the upper terminal and the release paper of the winding reel 13 increases, the reaction force on the pressure roller 20 changes, and the pressure sensor transmits the pressure data to the controller in real time. If the pressure is greater than the target value, the controller drives the electric telescopic rod 16 to retract upward, reducing the downward pressure of the pressure roller 20. If the pressure is less than the target value, the electric telescopic rod 16 extends downward, increasing the downward pressure. At the same time, the buffer spring 22 adaptively absorbs thickness fluctuations.

[0024] winding component alternating switching phase When the currently operating take-up component reaches the set take-up length threshold or count threshold, the device automatically performs a switching operation: The controller 24 first pauses the current take-up motor 12, and at the same time drives the rotary motor 8 to run, causing the turntable 7 to rotate 180°, so that another empty take-up assembly is moved to the take-up station, and the original working assembly is moved to the disassembly station. After the rotation is in place, the controller immediately starts the take-up motor 12 of the new take-up assembly and adjusts the electric telescopic rod 16 to restore the pressure roller 20 to the target pressure force. During the operation of the new assembly, the operator can manually unscrew the cover 14, remove the fully wound take-up reel 13 on the disassembly station, and replace it with an empty take-up reel to prepare for the next switchover.
