Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an automatic lamp holder return device. Background Technology
[0002] An automatic lamp head repositioning device is a mechanical device that uses the elastic potential energy of a spring to automatically reset the lamp head. It stores the deformation energy under external force through a spring assembly, releasing the energy after the force disappears, causing the lamp head to return to its initial position along a preset trajectory. This is an automated piece of equipment used in lamp production lines. Its main function is to automatically adjust the position and angle of the lamp head during assembly and inspection processes, ensuring its precise return to a preset workstation and guaranteeing stable and efficient operation of subsequent processes. It typically combines mechanical transmission, sensor detection, and a spring-assisted repositioning structure. When the lamp head has moved or shifted after a previous process, the device uses sensors to identify the positional deviation, drives mechanical components to adjust the lamp head's posture, and simultaneously utilizes the elastic potential energy of the spring to assist the lamp head in quickly resetting to the standard position, improving the automation level and assembly accuracy of the production line.
[0003] The automatic spring-loaded return device for adjusting items has a core structure including a spring assembly, a guide and limit structure, an adjustment component, and a transmission component. When the lamp head is transported to the device station along the assembly line, the sensor detects its positional deviation, and the drive unit adjusts the angle and position of the lamp head through a push rod or rotation mechanism. At the same time, the spring assembly stores potential energy during the adjustment process. When the lamp head reaches the standard position, the drive unit releases the force, and the spring releases energy to help the lamp head accurately lock into the positioning groove, completing the return.
[0004] However, in the existing technology, the automatic lamp holder return device uses springs for a long time, which can lead to insufficient spring tension and the need to replace the springs, significantly increasing capital investment. Adjusting the connection method between lamp holder components makes the product assembly too cumbersome, seriously affecting the quick replacement and application of the automatic lamp holder return device. Therefore, an automatic lamp holder return device is proposed to solve the above problems. Utility Model Content

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.
[0012] Reference Figures 1 to 3An embodiment of this utility model provides an automatic lamp head repositioning device, including a base plate 1, which is mainly used to support the entire structure. A fixing column 2 is fixedly connected to the top of the base plate 1, and a main support column 4 is fixedly connected to the top of the base plate 1. The main support column 4 is used to support the upper part of the structure. A side plate 7 is fixedly connected to the front side of the main support column 4. When the side plate 7 rotates, important components can better enable the entire structure to rotate. A replacement mechanism 3 is fixedly connected to the right side of the side plate 7. The replacement mechanism 3 mainly stores a structure that can easily disassemble the entire component. An adjustment rod 5 is fixedly connected to the top of the main support column 4, and a disassembly mechanism 6 is fixedly connected to the top of the adjustment rod 5. The replacement mechanism 3 includes two guide posts 31, which are fixedly connected to the right side of the side plate 7. The guide posts 31 are used to guide the upper part of the nut into place, making the structure more stable. Two clamps 32 are fixedly connected to the outside of each guide post 31. The clamps 32 are mainly used to clamp the nut cylinder in the guide post 31 to create a fixation. Moving plates 33 are fixedly connected to the far sides of the multiple clamps 32. The moving plates 33 are mainly connected to the multiple clamps 32 to make the clamps 32 move. A stop plate 34 is slidably connected to the near side of the two moving plates 33. The stop plate 34 transmits the force brought by the control post 35. The control post 35 is fixedly connected to the far side of the two stop plates 34. The control post 35 receives the operation required in the whole structure. A button 36 is fixedly connected to the far side of the two control posts 35. A protective component 37 is slidably connected to the outside of the control post 35.
[0013] Reference Figures 2 to 4 The disassembly mechanism 6 includes a plug rod 61, which ensures the integrity of the entire internal structure. The plug rod 61 is fixedly connected to the bottom of the adjusting rod 5 at the top. A concave plate 62 is slidably connected to the outside of the plug rod 61. Multiple abutments 63 are fixedly connected to the outside of the plug rod 61. The abutments 63 are used to fix the inserted part. A convex plate 64 is fixedly connected to the bottom of the plug rod 61. When disassembly is required, the convex plate 64 can make the abutments 63 move and retract. A spring 65 is fixedly connected to the outside of each of the multiple abutments 63. The spring 65 mainly makes the abutments 63 move inward to fix the internal structure. A support column cover 66 is fixedly connected to the bottom of the convex plate 64. A support column 67 is fixedly connected to the outside of the support column cover 66. A spring 68 is slidably connected inside the support column 67.
[0014] Reference Figures 3 to 6The protective assembly 37 includes two housings 371, which protect the internal components from weathering and wear, as well as dust ingress. The right sides of the two housings 371 are fixedly connected to the left side of the side plate 7. Abutments 372 are fixedly connected to both sides of the two housings 371. The abutments 372 on both sides are mainly to ensure the clamping force applied by the two moving plates 33 in the middle, preventing the nuts in the guide posts 31 from slipping and causing machine damage. The outer side of the support cover 66 is fixedly connected to the inner wall of the support post 67. The bottom of the support cover 66 is fixedly connected to the top of the second spring 68. The second spring 68 mainly ensures that the mechanism does not fall during machine operation, preventing automatic detachment and thus avoiding structural damage. The bottom of the concave plate 62 is slidably connected to the outside of multiple abutments 63. The concave plate 62 is mainly used to move the convex plate 64 upwards when pressed down and then lifted, allowing the entire structure to be removed. The top of the convex plate 64 is slidably connected to the bottom of the abutments 63, securing the convex plate 64 to prevent the structure from falling off. The two control posts 35 are slidably connected to the inner walls of the two housings 371 at their far ends. Multiple housings 371 protect the sliding stability of the two control posts 35. Multiple abutment posts 372 are fixedly connected to the far ends of multiple movable plates 33 at their near ends. The two buttons 36 are slidably connected to the far ends of the two housings 371 at their near ends. The outer side of the guide post 31 is fixedly connected to the inside of the housing 371. The left side of the fixed post 2 is fixedly connected to the right side of the housing 371. The outer side of the movable plate 33 is slidably connected to the inner wall of the housing 371. The movable plate 33 is on the inner wall of the housing 371 to ensure accurate sliding and prevent it from shifting and falling off.
[0015] Working principle: When the spring tension is insufficient and the spring needs to be replaced, press the buttons 36 at both ends inward. When pressed, the buttons 36 fix the control column 35 and move it. The control column 35 is connected to the abutment plate 34 and squeezes inward. At the same time, it squeezes the moving plates 33 on both sides and moves them to both sides. Along with the moving plates 33 and the clamp 32, they move to both sides. At the same time, the clamp 32 loosens the nut in the guide column 31 and removes the nut. The spring can be easily removed. After replacement, the clamp 32 is inserted again. The abutment column 372 on both sides has elasticity to squeeze the two moving plates 33 to clamp the nut, thereby achieving the purpose of quickly replacing the spring.
[0016] When the upper part of the disassembly mechanism 6 is damaged, the disassembly mechanism 6 can be pressed down to move the insertion rod 61 downward, causing the concave plate 62 sliding on the insertion rod 61 to move downward. As the concave plate 62 is pulled upward by the abutment tooth 63, it connects with the convex plate 64 and passes through the abutment post 372 together. After replacing the part, press down once to make the convex plate 64 pass through the abutment tooth 63. The abutment tooth 63 is stuck between the concave plate 62 and the convex plate 64 and is supported by the support post 67 to prevent downward movement. When it is stuck, the entire insertion rod 61 cannot be pulled out, which can fix the top part, thereby achieving the purpose of quick replacement.
[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
