[0002] The coil former is the core structure of electromagnetic components such as inductor, transformer, and the assembly quality and efficiency of its pin directly affect the electrical performance and production cost of components. At present, the assembly of coil former pin in the industry mainly adopts step-by-step automatic assembly mode: some automatic equipment on the market, its process flow is mostly completed separately or step by step.
[0003] The common practice is: first, the straight pin is inserted into the former through the feeding mechanism such as vibration disc; after completing the pin insertion of a batch of former, the whole workpiece is transferred to the next independent work station for unified bending, which is specially used for bending. This step-by-step automatic scheme has the following inherent defects: the whole production line needs two or more sets of independent equipment and control system for insertion and bending, which occupies a large area, has high equipment cost, and the material transfer between different work stations increases the production rhythm, which limits the further improvement of overall efficiency. The workpiece needs to be transferred and repositioned between the insertion station and the bending station, which may produce cumulative error, resulting in inaccurate bending position and affecting product consistency. During the transfer process, the straight pin that is only inserted but not fixed may be loose or fall off, which affects the yield of subsequent bending process.
[0004] In summary, the existing technology, whether it is pure manual or step-by-step automatic mode, has the problems of low production efficiency, poor product consistency and complicated process flow. Therefore, there is an urgent need in the field for a high-efficiency automatic assembly scheme that can realize the integration of pin insertion and bending and continuous completion, so as to fundamentally overcome the above-mentioned defects.

This time sequence logic of "first positioning, then insertion, and then bending" avoids the risk of interference and collision, ensuring the stability and reliability of the bending process and the repeatability precision.

DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0023] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, the term "installation", "set with", "connection" and so on, should do broad sense understanding, for example "connection", can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through intermediate medium, can be two elements inside the communication.For the ordinary skill in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.
[0024] As Figures 1-5 The utility model discloses a coil former pin insertion mechanism, including frame 1, be equipped with on frame 1: the positioning fixture 2 for fixing coil former 5, the feeding track 3 for conveying pin 6, and its export is opposite the insertion hole 4 of coil former 5, linear pusher mechanism 7 is set up in the feeding track 3 relative positioning side of tool, for pin 6 is pushed into the insertion hole 4 of coil former 5, the bending assembly 8 is located below the positioning fixture 2, including the inclined arrangement push plate 9 and the linear driver 10 of driving push plate 9, push plate 9 is equipped with the receiving part 11 for receiving the inner end of pin 6, when pin 6 is pushed into the insertion hole 4, and its inner end is located in the receiving part 11, and linear driver 10 drives push plate 9 to extend, and the inner end of pin 6 is realized bending by the receiving part 11 resistance and extrusion.
[0025] The key improvement of the application is the cooperation and timing logic between the two processes of insertion and bending, which is not dependent on complex programmed electric control system, but realized by the inherent properties of the spatial layout and mechanical configuration of the mechanism itself. Specifically, the push plate 9 is driven by its linear driver 10 and can be moved and stabilized in the "waiting position" in advance. At this position, the spatial coordinates of the receiving part 11 (such as the bending mouth 14) on the push plate 9 correspond to the final inner end position of the pin 6 after being pushed by the linear pusher mechanism 7. When the linear pusher mechanism 7 performs its single linear push-in action, the inner end of the pin 6 will inevitably be sent into the pre-set receiving part 11.
[0026] The two key processes of pin insertion and bending are integrated on one equipment to be completed continuously and automatically. Through the cooperative action of the linear pusher mechanism 7 and the bending assembly 8, the full-process automation from feeding, accurate insertion to immediate bending is realized, greatly shortening the production rhythm of single product and improving the assembly efficiency. Since the coil former 5 only needs to be clamped and positioned once on the positioning fixture 2, the insertion and bending can be completed in turn, avoiding the cumulative error caused by the transfer of workpieces between different stations. This ensures the accuracy and consistency of the insertion depth, bending angle and position of the pin 6, effectively improving the yield and reliability of the product.
[0027] The push plate 9 is arranged at an acute angle with the horizontal plane; the linear driver 10 drives the push plate 9 to reciprocate along the inclined direction. The bottom of the frame 1 is provided with a support frame 12 with an inclined support surface 13, the linear driver 10 is fixed on the support surface 13, and the inclination angle of the support surface 13 is the same as that of the push plate 9. The push plate 9 of the bending assembly 8 is arranged at an inclination, and the linear driver 10 driving the push plate 9 is installed through the support frame 12 with the same inclination angle. This design makes the thrust direction of the driver completely parallel to the movement path of the push plate 9, realizes direct power transmission without component wear and loss, reduces component wear, and enhances the movement stability of the push plate 9.
[0028] The receiving part 11 of the push plate 9 is a bending opening 14 opened on the side wall of the side facing the pin 6; before the linear pushing mechanism 7 acts, the bending opening 14 has moved to a predetermined position corresponding to the insertion path of the pin 6. Before the linear pushing mechanism 7 of the bending assembly 8 acts, the push plate 9 has been moved in advance and positioned on the movement path of the inner end of the pin 6. This design makes the inner end of the pin 6 accurately and without interference into the receiving part 11 after insertion, and then performs the bending action. This time sequence logic of "first positioning, then inserting, and then bending" avoids the risk of interference and collision, and ensures the stability and repeatability of the bending process.
[0029] Two track grooves 15 for accommodating the pins 6 are arranged side by side on the feeding track 3; the driving end of the linear pushing mechanism 7 is fixedly connected with two insertion plates 16 which are in one-to-one correspondence with the two track grooves 15, so as to synchronously push the pins 6 in the two track grooves 15.
[0030] The linear pushing mechanism 7 in the embodiment is a linear driving element, which is one of a pneumatic cylinder, a hydraulic cylinder, an electric push rod or a linear motor. The linear driver 10 is one of a pneumatic cylinder, a hydraulic cylinder, an electric push rod or a linear motor.
[0031] The basic principle, main features and advantages of the present application have been shown and described. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
