Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic equipment processing technology, specifically to a novel tension spring mechanism. Background Technology
[0002] In small electronic devices and automated control components, the tension spring mechanism is a key actuator and is widely used in the triggering control of micro switches. Its core function is to drive the micro switch spring to complete the mechanical triggering action through the extension and contraction of the tension spring, so as to realize the switching of the circuit.
[0003] The existing novel tension spring mechanism mainly consists of a tension spring, a micro switch spring, and a mounting base. During assembly, both ends of the tension spring need to be hooked onto the hooks on the base and the attachment points of the micro switch spring, respectively. However, in actual mass production, due to limitations in existing assembly processes, the installation of the micro switch spring and the tension spring is prone to deviation. Specifically, due to stamping precision or assembly positioning errors, the attachment point of the micro switch spring is prone to shifting. At the same time, during manual or semi-automatic attachment operations, it is difficult to accurately align the tension spring with the attachment point, leading to tension spring attachment failure or misalignment. Summary of the Invention
[0004] The purpose of this invention is to provide a novel tension spring mechanism to solve the problems mentioned in the background art.
[0005] This novel tension spring mechanism includes a frame, a first electric push rod disposed on one side of the frame, a movable plate keyed to the output end of the first electric push rod (activating the first electric push rod causes its output end to push the movable plate laterally), a mounting bracket slidably disposed on one side of the movable plate, a second electric push rod disposed on one side of the movable plate with its output end keyed to the mounting bracket (activating the second electric push rod causes its output end to push the mounting bracket longitudinally), and a connecting bracket disposed on the mounting plate. On one side of the mounting frame, there is a second clamping spring cylinder, which is located on one side of the connecting frame; a fourth electric push rod, which is located on one side of the connecting frame; a push plate, which is keyed to the output end of the fourth electric push rod; a first clamping spring cylinder, which is located on one side of the push plate; the first and second clamping spring cylinders will simulate manual assembly to improve product yield; and a third electric push rod, which is located on one side of the push plate, and the output end of the third electric push rod is keyed to one side of the first clamping spring cylinder.

[0011] By adopting the above technical solution, the yield rate of tension springs can be improved by simulating manual assembly.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel tension spring hanging mechanism, through the cooperation between the first tension spring clamping cylinder and the second tension spring clamping cylinder, after the first tension spring clamping cylinder and the second tension spring clamp the two ends of the tension spring respectively, the displacement of the first tension spring clamping cylinder will cause the tension spring to be quickly stretched, and the longitudinal movement of the first tension spring clamping cylinder and the second tension spring clamping cylinder will cause the tension spring to be quickly installed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0018] Please see Figure 1-10This utility model provides a technical solution: a novel tension spring mechanism, including a frame 1 and a clamp 5. Two sets of first slide rails 8 are fixedly connected to one side of the frame 1. A mounting platform 25 is provided inside the clamp 5, which is located on one side of the frame 1. A first electric push rod 2 is fixedly connected to one side of the frame 1. The output end of the first electric push rod 2 is keyed to a moving plate 9, which is slidably connected to the outside of the two sets of first slide rails 8. Two sets of second slide rails 10 are also fixedly connected to one side of the moving plate 9. A second electric push rod 4 is fixedly connected to one side of the moving plate 9. The output end of the second electric push rod 4 is keyed to a mounting bracket 11, which is slidably connected to... On the outer side of the two sets of second slide rails 10, a connecting frame 15 is fixedly connected to one side of the mounting frame 11. A second clamping spring cylinder 14 is fixedly connected to one side of the connecting frame 15. A fourth electric push rod 16 is fixedly connected to the side of the connecting frame 15 away from the second clamping spring cylinder 14. A push plate 12 is keyed to the output end of the fourth electric push rod 16. A third electric push rod 6 is fixedly connected to one side of the push plate 12. A first clamping spring cylinder 13 is keyed to the output end of the third electric push rod 6. The first clamping spring cylinder 13 is slidably connected to one side of the push plate 12. The first clamping spring cylinder 13 and the second clamping spring cylinder 14 are parallel. A conveying device 3 is provided on one side of the frame 1.
[0019] A support plate 18 is fixedly connected to one side of the frame 1, and a fifth electric push rod 19 is fixedly connected to one side of the support plate 18. A baffle 17 is keyed to the output end of the fifth electric push rod 19, and the baffle 17 is engaged inside the conveying device 3. After the fifth electric push rod 19 is turned on, its output end will push the baffle 17 to move laterally. After the baffle 17 is disengaged from the conveying device 3, the tension spring inside the conveying device 3 is no longer blocked. However, after the baffle 17 is engaged in the conveying device 3, the tension spring inside the conveying device 3 will be blocked and cannot disengage from the conveying device 3.
[0020] A placement frame 20 is fixedly connected to one side of the frame 1. A connecting shaft 26 is rotatably installed inside the placement frame 20. One end of the connecting shaft 26 passes through the placement frame 20 and is keyed to the fixed frame. A third clamping spring cylinder 22 is fixedly connected to one side of the fixed frame. A gear 21 is keyed to the outer side of the output end of the connecting shaft 26. A rack 23 is slidably connected inside the placement frame 20, and the rack 23 meshes with the gear 21. An operating block 24 is fixedly connected to the outer side of the rack 23. A fixing hole is opened on one side of the operating block 24. One side of the frame 1 is fixed. A rotary cylinder 7 is connected. When the connecting shaft 26 rotates, it will drive the fixed frame to rotate. The rotation of the fixed frame will drive the third clamping spring cylinder 22 to rotate. After the rotary cylinder 7 is turned on, the output end of the rotary cylinder 7 will drive the gear 21 to rotate by driving the operating block 24 to move laterally. The rotation of the gear 21 will drive the third clamping spring cylinder 22 to rotate by driving the connecting shaft 26 to rotate. Thus, the tension spring clamped by the third clamping spring cylinder 22 is located below the first clamping spring cylinder 13 and the second clamping spring cylinder 14.
[0021] Two sets of fiber optic detection sensors are installed on one side of the frame 1, and the two sets of fiber optic detection sensors correspond to the first clamping spring cylinder 13 and the second clamping spring cylinder 14 and the outlet of the conveying device 3, respectively. A controller is installed inside the frame 1, and the controller is connected to the first electric push rod 2, the second electric push rod 4, the third electric push rod 6, the rotary cylinder 7, the first clamping spring cylinder 13, the second clamping spring cylinder 14, the fourth electric push rod 16, the fifth electric push rod 19 and the third clamping spring cylinder 22, respectively.
[0022] In operation, the fiber optic sensor detects the tension spring at the outlet of the conveyor 3 and transmits a signal to the controller. The controller then activates the fifth electric push rod 19, causing its output to move the baffle 17. The baffle 17 then disengages from the conveyor 3 and no longer obstructs the tension spring. The controller then activates the third tension spring cylinder 22 to clamp the tension spring at the outlet of the conveyor 3. The rotary cylinder 7 then activates, causing its output to push the rack 23 laterally via the operating block 24. The movement of the rack 23 drives the gear 21 to rotate, which in turn drives the connecting shaft 26, causing the third tension spring cylinder 22 to rotate. The tension spring clamped by the third tension spring cylinder 22 is located below the first tension spring cylinder 13 and the second tension spring cylinder 14. The second electric push rod 4 then activates, causing its output to push the mounting bracket 11 downwards, which in turn pushes the connecting bracket 15 downwards. The downward movement of the connecting bracket 15 causes the first tension spring cylinder 13 and the second tension spring cylinder 14 to rotate. Contact both ends of the tension spring. At this time, activate the first tension spring clamping cylinder 13 and the second tension spring clamping cylinder 14, so that both ends of the tension spring are clamped by the first tension spring clamping cylinder 13 and the second tension spring clamping cylinder 14 respectively. Then, activate the third electric push rod 6 to push the first tension spring clamping cylinder 13 to move longitudinally. At this time, the tension spring is kept at one side high and the other side low for easy installation. At the same time, activate the fourth electric push rod 16 to push the first tension spring clamping cylinder 13 to move laterally by pushing the push plate 12. At this time, the tension spring is opened. Then, activate the first electric push rod 2 so that its output end pushes the first tension spring clamping cylinder 13 and the second tension spring clamping cylinder 14 to move by pushing the moving plate 9. Position the first tension spring clamping cylinder 13 and the second tension spring clamping cylinder 14 above the mounting platform 25. After the output end of the second electric push rod 4 continues to descend, the tension spring between the first tension spring clamping cylinder 13 and the second tension spring clamping cylinder 14 will be quickly and stably installed onto the micro switch on the mounting platform 25, completing the installation of the tension spring.
[0023] This novel tension spring hanging mechanism, through the cooperation between the first tension spring clamping cylinder 13 and the second tension spring clamping cylinder 14, allows the tension spring to be quickly stretched by the displacement of the first tension spring clamping cylinder 13 after the two clamping cylinders 13 and 14 clamp the two ends of the tension spring respectively. The longitudinal movement of the first tension spring clamping cylinder 13 and the second tension spring clamping cylinder 14 allows the tension spring to be quickly installed. This device can improve the product yield by simulating manual assembly and avoid the situation where it is difficult to accurately align the spring clip hanging point, resulting in tension spring hanging failure or misalignment.
