[0024] In order to make the purpose, technical scheme and advantages of the implementation mode of the utility model clearer, the technical scheme in the implementation mode of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation mode of the utility model. Obviously, the described implementation mode is a part of the implementation mode of the utility model, not all of the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the implementation mode of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected implementation mode of the utility model. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Depend on Figures 1 to 7As shown, an embodiment of the utility model provides a spring insertion mechanism, including a lifting and positioning mechanism 1, a magnetic circuit product 2, a normally closed static spring 3 and a tool 4 for placing the magnetic circuit product 2. The tool 4 is located above the output end of the lifting and positioning mechanism 1 and can be placed on a workbench or a transmission device. The lifting drive cylinder and the positioning pin of the lifting and positioning mechanism 1 pass through the workbench to position the tool 4. In this application, it has been determined that the magnetic circuit product 2 is at the required positioning position to insert the normally closed static spring 3, so no further details are given here.

[0026] Among them, the spring insertion mechanism includes a dynamic spring lifting mechanism 5 and a static spring insertion mechanism 6; the static spring insertion mechanism 6 is arranged on one side of the lifting and positioning mechanism 1, and the dynamic spring lifting mechanism 5 is arranged on the lifting and positioning mechanism 1; it can effectively utilize the space to make the whole device more compact.

[0027] At this time, since the positioning pin of the lifting and positioning mechanism 1 is inserted into the tooling 4 to complete the positioning, the plug-in interface 7 of the magnetic circuit product 2 located on the tooling 4 is just aligned with the output direction of the output end of the static spring insertion mechanism 6, and, at the same time, the output end of the dynamic spring lifting mechanism 5 is located below the dynamic spring 8 of the magnetic circuit product in the plug-in interface 7, and the bottom of the plug-in interface 7 is also opened. Next, when the dynamic spring lifting mechanism 5 lifts the dynamic spring 8 of the magnetic circuit product, the static spring insertion mechanism 6 pushes the normally closed static spring 3 located on the output end of the static spring insertion mechanism 6 into the plug-in interface 7, and extends from below the dynamic spring 8 of the magnetic circuit product for assembly.

[0028] Preferably, the static spring insertion mechanism 6 includes an insertion drive cylinder 9, a slide rail 10, a mounting seat slider group 11, a guide groove slider group 12 and a driving spring 13; the mounting seat slider group 11 and the guide groove slider group 12 are respectively arranged on the slide rail 10; the two ends of the driving spring 13 are respectively connected to the mounting seat slider group 11 and the guide groove slider group 12; the output end of the insertion drive cylinder 9 is connected to the mounting seat slider group 11; the upper end of the guide groove slider group 12 is provided with a guide groove 14 suitable for placing the normally closed static spring 3, and the normally closed static spring 3 and the guide groove 14 can slide smoothly relative to each other; the mounting seat slider group 11 is provided with a push rod 15 for pushing the normally closed static spring 3 from the guide groove 14 into the insertion interface 7. Among them, when the plug-in drive cylinder 9 drives the mounting seat slider group 11 to move forward on the slide rail 10, the drive spring 13 will first push the guide groove slider group 12 to move forward. Since the magnetic circuit product 2 has been positioned, the opening at the front end of the guide groove slider group 12 can be aligned with the magnetic circuit product 2 and adapted to play a secondary positioning role after being close. At this time, after plugging, it is aligned with the port of the guide groove 14, and the guide groove slider group 12 stops moving at this time. As an implementation method, it can be limited by the limit screw 16 installed on one side against the workbench. Further, when the guide groove slider group 12 stops moving, the mounting seat slider group 11 compresses the drive spring 13 and continues to move forward, so that the push rod 15 gradually pushes the normally closed static spring 3 on the guide groove 14 toward the port of the guide groove 14.

[0029] Among them, as a preferred embodiment, the dynamic spring lifting mechanism 5 includes a track plate driving block 17, a lifting track plate 18 and a lifting block 19; the lifting and positioning mechanism 1 is provided with a slide groove 20 suitable for the lifting track plate 18 to move forward and backward; one end of the track plate driving block 17 is installed on the mounting seat slider group 11, and the other end is connected to the lifting track plate 18, which is used to drive the lifting track plate 18 to move forward and backward; the lifting and positioning mechanism 1 is also provided with a through groove 21 suitable for the lifting block 19 to pass through in the longitudinal direction, the lower end of the lifting block 19 is against the lifting track plate 18, and the upper end passes through the tooling 4 and is located below the dynamic spring 8 of the magnetic circuit product, which is used to lift the dynamic spring 8 of the magnetic circuit product.

[0030] It should be noted that, at the same time, in the process of the mounting seat slider group 11 moving and pushing the normally closed static spring 3, the track plate drive block 17 is driven forward at the same time, and the lifting track plate 18 is driven to move forward in the slide groove 20. The bottom end of the lifting block 19 is pushed by the slope of the lifting track plate 18. The lifting block 19 is radially restricted in the through groove 21 and moves upward along the slope in the longitudinal direction. The end passes through the tooling 4 and lifts the magnetic circuit product dynamic spring 8 from the bottom of the plug-in interface 7. At the same time, the push rod 15 synchronously pushes the normally closed static spring 3 to complete the insertion. When the insertion drive cylinder 9 drives the mounting seat slider group 11 to move backward, the lifting block 19 falls down to complete the assembly.

[0031] Among them, it can be known that the lifting block 19 can be set to be arc-shaped at the bottom to contact the slope. As a preferred embodiment, a follower bearing 22 can be installed at the lower end of the lifting block 19 to roll relative to the slope, making it smoother when rising or falling.

[0032] Furthermore, a downward slot hole can be provided in the through slot 21, and a return spring 23 can be provided between the lifting block 19 and the slot top. The return spring 23 can generate a downward force on the lifting block 19, thereby helping the lifting block 19 to be quickly retracted when it returns to the lower end of the lifting track plate 18.

[0033] It can be known that when the lifting and positioning mechanism 1 completes the positioning of the tooling 4, it will drive the internal dynamic spring lifting mechanism 5 to move upward in advance. At this time, the end of the lifting block 19 will not extend into the plug-in port 7, but will be just below the dynamic spring 8 of the magnetic circuit product for waiting, thereby reducing the lifting stroke of the dynamic spring lifting mechanism 5 and improving efficiency. Furthermore, since the lifting track plate 18 will move in the longitudinal direction, the track plate driving block 17 and the lifting track plate 18 are connected by longitudinal plug-in, so that they can limit the radial position and drive the movement while not affecting each other in the longitudinal direction.

[0034] Preferably, it also includes a detection photoelectric device 24 and an insertion-in-place detection piece 25 for detecting whether the normally closed static spring 3 is successfully installed. The detection photoelectric device 24 and the insertion-in-place detection piece 25 are installed on one side of the static spring insertion mechanism 6 to detect whether the magnetic circuit product 2 after plug-in assembly is successfully assembled.

[0035] The present application also provides a reed assembly machine, including the reed insertion mechanism described above. After positioning is completed, the dynamic spring 8 of the magnetic circuit product is first lifted up, and then the normally closed static spring 3 is inserted to complete efficient automated installation, with higher precision, compact overall structure, lower cost and higher quality of the assembled product.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
