Detailed implementation manners

[0063] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0064] Embodiment 1

[0065] An automatic pressing device for a PC lamp shade of a lighting fixture, as Figures 1-11 shown, includes a support frame 1. A conveyor assembly 2 is arranged on the upper part of the support frame 1. A mounting backplate 3 is installed at the rear of the support frame 1. A first cylinder 4 is arranged on the front side of the upper part of the mounting backplate 3. The telescopic rod of the first cylinder 4 is downwardly oriented. A pressing plate 5 is arranged on the telescopic rod of the first cylinder 4. The pressing plate 5 is used for pressing the PC lamp shade. It further includes: a clamping mechanism 6, which is arranged on the pressing plate 5 and is used for clamping and stabilizing the PC lamp shade; a positioning mechanism 7, which is arranged between the support frame 1 and the mounting backplate 3 and is used for centering the PC lamp shade to prevent the lamp shade from shifting; a buffer mechanism 8, which is arranged on the pressing plate 5 and is used for providing buffer protection for the PC lamp shade to prevent the lamp shade from being damaged.

[0066] It should be noted that during the process of pressing the PC lamp shade, this device can be used for operation assistance. First, place the lamp shade on the conveyor assembly 2, and then transport the lamp shade through the conveyor assembly 2 so that the lamp shade moves below the pressing plate 5. When the lamp shade approximately moves below the pressing plate 5, at this time, control the positioning mechanism 7 to push the lamp shade so that the lamp shade can be aligned with the pressing plate 5. Then control the telescopic rod of the first cylinder 4 to move so that the pressing plate 5 gradually approaches the lamp shade. After that, control the clamping mechanism 6 to clamp and stabilize the lamp shade. At the same time, as the pressing plate 5 moves downward, the buffer mechanism 8 will be automatically triggered to provide buffer protection for the upper part of the lamp shade being pressed.

[0067] The clamping mechanism 6 includes a driving motor 61. The driving motor 61 is installed inside the pressure plate 5. A gear 62 is installed on the output shaft of the driving motor 61. Four racks 63 are slidably connected inside the pressure plate 5. The racks 63 are meshed with the gear 62. First clamping plates 64 are connected to the outer sides of the racks 63. The first clamping plates 64 are all made of soft materials and are used to stably clamp the lamp cover.

[0068] It should be noted that as the pressure plate 5 moves downward, the rotation of the output shaft of the driving motor 61 is controlled, so that the gear 62 starts to rotate. During the rotation of the gear 62, the racks 63 will be driven to move, so that the first clamping plates 64 move synchronously until the first clamping plates 64 contact the outer edge of the lamp cover, then the driving motor 61 is turned off. The soft structure of the first clamping plates 64 is used to fit and clamp the lamp cover to ensure the stability of the lamp cover during the pressing process.

[0069] The positioning mechanism 7 includes a second cylinder 71. The second cylinder 71 is installed on the lower part of the mounting back plate 3 and the upper side of the front part of the support frame 1. The telescopic rods of the second cylinder 71 are all outward-facing. The telescopic rods of the second cylinder 71 are provided with a retraction distance. First sliding frames 72 are connected to the telescopic rods of the second cylinder 71. Positioning plates 73 are arranged inside the first sliding frames 72. The left sides of the positioning plates 73 are all inclined plane structures.

[0070] It should be noted that when the conveying assembly 2 conveys the lamp cover, the movement of the telescopic rods of the second cylinder 71 is controlled to make the first sliding frames 72 slide outward and unfold. When the lamp cover roughly moves below the pressure plate 5, the telescopic rods of the second cylinder 71 are controlled to contract and reset, so that the first sliding frames 72 drive the positioning plates 73 to move inward and reset, thereby pushing the lamp cover so that the lamp cover can be exactly below the pressure plate 5, preventing the lamp cover from shifting and reducing the pressing error rate.

[0071] It further includes a buffer mechanism 8. The buffer mechanism 8 includes a fixing plate 81. The fixing plate 81 is connected to both the front and rear sides of the pressure plate 5. Second sliding frames 82 are slidably connected to the outer ends of the fixing plates 81. The second sliding frames 82 are perpendicular to the adjacent fixing plates 81. Springs 83 are connected between the second sliding frames 82 and the adjacent fixing plates 81. Fixed seats 84 are installed on the upper sides of the fixing plates 81. Connecting rods 87 are rotatably connected to the fixed seats 84. The connecting rods 87 are rotatably connected to the adjacent second sliding frames 82. A lifting frame 85 is slidably connected inside the pressure plate 5. An airbag 86 is installed at the bottom of the lifting frame 85. The lifting frame 85 is rotatably connected to the adjacent connecting rod 87.

[0072] It should be noted that as the pressure plate 5 starts to move downward, the second sliding frame 82 will also move downward synchronously. As the second sliding frame 82 comes into contact with the conveying component 2, the second sliding frame 82 will slide upward. At this time, the springs 83 will all be compressed under force. When the second sliding frame 82 slides upward, the connecting rods 87 will all be pulled by the adjacent second sliding frames 82 and thus turn inward. During this process, the inner sides of the connecting rods 87 will all push the lifting frame 85 downward. At this time, the lifting frame 85 drives the airbag 86 to move downward, and relies on the airbag 86 to contact the upper side of the lamp cover to buffer and protect the lamp cover being pressed, avoiding direct contact between the pressure plate 5 and the lamp cover, which may cause damage and breakage of the lamp cover. After the pressing is completed and the pressure plate 5 moves upward to reset, the second sliding frame 82 gradually disengages from the conveying component 2. Under the action of the springs 83, the second sliding frames 82 will all slide downward to reset, so that the connecting rods 87 pull the lifting frame 85 to slide upward to reset, and further the airbag 86 disengages from the lamp cover.

[0073] Embodiment 2

[0074] On the basis of Embodiment 1, it further includes a detection mechanism 9. The detection mechanism 9 includes a fixed frame 91. Two adjacent fixed frames 91 are connected to the right part of the support frame 1. Detection components 92 are installed on the fixed frames 91. The detection components 92 are used to detect the pressing effect of the lamp cover. The detection components 92 adopt the method of visual detection. Third cylinders 93 are connected to the upper parts of the fixed frames 91. Moving frames 96 are connected to the telescopic rods of the third cylinders 93. Fourth cylinders 94 are installed on the moving frames 96. The fourth cylinders 94 have a double telescopic rod structure. The detection components 92 are electrically connected to the corresponding third cylinders 93 and fourth cylinders 94. Second clamping plates 95 are connected to the telescopic rods of the fourth cylinders 94. The second clamping plates 95 are all slidably connected to the adjacent moving frames 96.

[0075] It should be noted that the pressed lamp cover will continue to move to the right through the conveying component 2. When the lamp cover moves below the detection component 92, the pressing effect of the lamp cover is visually detected by the visual detection method. If it is found that the pressing of the lamp cover is abnormal, the third cylinder 93 will be automatically started at this time, so that the moving frame 96 moves downward to place the lamp cover between the inner sides of the corresponding second clamping plates. Then, control the movement of the telescopic rod of the fourth cylinder 94 so that the second clamping plates can clamp the lamp cover that has not been successfully pressed. Then, control the telescopic rod of the third cylinder 93 to contract upward and reset to clamp the lamp cover upward, avoiding defective products from entering the subsequent production line.

[0076] It further includes a pushing mechanism 10. The pushing mechanism 10 includes a mounting frame 101. Six groups of symmetrically arranged front and rear mounting frames 101 are connected to the upper side of the left part of the support frame 1. Adjusting lead screws 102 are rotatably connected to the mounting frames 101. Lifting plates 103 are threadedly connected to the adjusting lead screws 102. The lifting plates 103 are slidably connected to the adjacent mounting frames 101. Roller wheels 104 are rotatably connected to the inner sides of the lifting plates 103. The roller wheels 104 are all used to assist the movement of the auxiliary lamp shade.

[0077] It should be noted that when placing the lamp shade, first, the adjusting lead screw 102 needs to be rotated according to the height of the lamp shade to adjust the height position of the lifting plate 103. After the adjustment is completed, the lamp shade is placed so that the lamp shade can pass under the roller wheels 104. During the movement of the lamp shade, on the one hand, the roller wheels 104 are relied on to push the lamp shade to move, and on the other hand, the roller wheels 104 are relied on to limit the position of the lamp shade to prevent the lamp shade from deviating significantly.

[0078] It further includes a synchronization mechanism 11. The synchronization mechanism 11 includes a latch member 111. Latch members 111 are connected to the outer sides of the first clamping plates 64. Adaptor members 112 are connected to the outer sides of the positioning plates 73. The latch members 111 can be engaged with the corresponding adaptor members 112.

[0079] It should be noted that when the pressure plate 5 moves downward, the pressure plate 5 will drive the first clamping plate 64 to move downward, so that the latch member 111 is engaged with the corresponding adaptor member 112. Then, as the first clamping plate 64 moves, the latch member 111 will pull the adaptor member 112 to move, thereby finely adjusting the position of the positioning plate 73 to make the positioning plate 73 fit the lamp shade more closely.

[0080] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
