Description
Technical Field
[0001] This utility model relates to the technical field of LED bulb production equipment, specifically to a bending edge mechanism suitable for automated production of LED bulbs. Background Technology
[0002] LED bulbs are common lighting fixtures, mainly composed of a lamp holder, lamp housing, bulb, and LED board. For example, in the production process of LED bulbs using E27 Edison screw-type lamp holders, before installing the E27 Edison screw-type lamp holder, it is necessary to pre-assemble the LED bulb body (such as the lamp housing and LED board) into a semi-finished product. Figure 3 As shown, after assembly on the LED bulb assembly line, the semi-finished bulb housing has two outward-extending power lines from its screw base. One is longer than the other; the longer power line is generally called the "center line," and the shorter one is called the "side line." Before installing the lamp holder, the side line needs to be bent to the screw base, and the excess length is cut off so that it fits precisely between the lamp holder and the screw base after installation. However, currently, the bending and cutting of the side line are done manually during production, resulting in a large number of workers, low efficiency, and difficulty in achieving automated production. Therefore, a device capable of automating the bending of the side line is needed. Summary of the Invention
[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a bending edge mechanism suitable for the automated production of LED bulbs, which can enable LED bulbs to achieve automatic bending of edges and improve the automation rate of LED bulb production.
[0004] To solve the aforementioned technical problems, this application adopts the following technical solution: A bending edge mechanism suitable for automated production of LED bulbs includes a clamping device for fixing the lamp housing, a positioning device for closing and limiting the long and short power lines extending from the screw hole of the lamp housing, and a bending device for directional bending of the closed and limited short power lines. After the housing with the LED light board is fixed by the clamping device, the long and short power lines are closed to the center position of the lamp housing by the positioning device, and finally the bending device bends the short power lines to form the edge.
[0005] Preferably, the clamping device includes a first fixing rod, a clamping cylinder disposed on the first fixing rod, and two lamp housing clamps disposed on the clamping cylinder. The two lamp housing clamps are opened and closed by the clamping cylinder, and the lamp housing is clamped and fixed by the two lamp housing clamps.
[0006] Preferably, the clamping cylinder is a Y-type pneumatic finger cylinder, and the two lamp housing clamps are respectively mounted on the two jaws of the clamping cylinder.
[0007] Preferably, the positioning device includes two symmetrically arranged wire clamps, which are respectively disposed on two lamp housing clamps and controlled by the clamping cylinder. The gap between the two wire clamps in the clamping state is located in the middle of the lamp housing opening.
[0008] Preferably, the bending device includes a second fixed rod, a lifting cylinder mounted on the second fixed rod, and a bending cylinder mounted on the lifting cylinder. The piston rod of the bending cylinder is provided with a right-angle push block, the top of the right-angle push block is provided with a pressing cylinder, and the piston rod of the pressing cylinder is provided with a bending slider, which is located inside the right-angle push block.
[0009] Preferably, the curved slider has a right-angle structure, and the curved slider in the retracted state is located inside the right-angle push block.
[0010] Preferably, the right-angle push block has two limiting blocks on its inner side, and a groove is formed between the right-angle push block and the limiting blocks, and the curved slider slides in the groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the short power cord extending from the screw hole of the lamp housing containing the LED light panel needs to be bent, the housing containing the LED light panel is fixed by a clamping device, and then the protruding power cords of both lengths are brought together to the center of the lamp housing by a positioning device. Finally, a bending device bends one of the power cords to form the edge line. By adding an edge-bending mechanism, the short power cord can be automatically bent to the outside of the screw hole of the lamp housing during the LED bulb production process. This achieves automatic edge-bending, increases the automation rate of LED bulb production, eliminates the manual bending step, reduces production costs, and improves work efficiency.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0016] like Figures 1-3 As shown, a bending edge mechanism suitable for automated production of LED bulbs mainly bends the short power lines 4 on the LED bulb semi-finished product. The LED bulb semi-finished product includes a housing, an LED light board disposed within the housing, a center line (long power line) and an edge line (short power line) disposed on the back of the LED light board. One end of the center line and the edge line protrudes through the screw hole of the housing. The bending edge mechanism includes a clamping device 2 for fixing the bulb housing 1, a positioning device 3 for closing and limiting the long and short power lines 4 extending from the screw hole of the bulb housing 1, and a bending device 5 for directional bending of the closed and limited short power lines 4. After the housing with the LED light board is fixed by the clamping device 2, the positioning device 3 closes the extended long and short power lines 4 to the center position of the bulb housing 1. Finally, the bending device 5 bends one of the short power lines to form an edge line.
[0017] In actual production, after the LED bulb semi-finished product is assembled, it is moved to the edge bending mechanism via a conveyor belt or turntable. Then, the clamping device 2 clamps and fixes the bulb housing 1 as a whole. Simultaneously, the positioning device 3 gathers and limits the lengths of the power cables 4, ensuring their extension lengths are within a specific area, typically the center of the screw thread on the bulb housing 1. Finally, the bending device 5 bends the shorter power cable 4 outwards from the screw thread to form an edge. This allows the bulb head to be easily inserted or screwed into the screw thread during subsequent assembly. By adding the edge bending mechanism during the bending of the shorter power cable, the LED bulb can automatically bend its edge to the outside of the screw thread on the bulb housing 1 during production. This achieves automatic edge bending, increases the automation rate of LED bulb production, eliminates the manual bending step, reduces production costs, and improves work efficiency.
[0018] A further improvement is made to the clamping device 2, which includes a first fixing rod 21, a clamping cylinder 22 mounted on the first fixing rod 21, and two lamp housing clamps 23 mounted on the clamping cylinder 22. The two lamp housing clamps 23 are opened and closed by the clamping cylinder 22, and the lamp housing 1 is clamped and fixed by the two lamp housing clamps 23. The clamping cylinder 22 is a Y-type pneumatic finger cylinder, and the two lamp housing clamps 23 are respectively mounted on the two jaws of the clamping cylinder 22.
[0019] The clamping device 2 consists of a first fixed rod 21 installed beside the conveyor line, a clamping cylinder 22 installed on the first fixed rod 21, and two lamp housing clamps 23 installed on the clamping cylinder 22. The two lamp housing clamps 23 can be opened and closed by the clamping cylinder 22. When clamping and fixing the lamp housing 1 on the conveyor line, the two lamp housing clamps 23 are unfolded by the clamping cylinder 22, which can prevent the lamp housing clamps 23 from obstructing the products on the conveyor line. When it is necessary to clamp the lamp housing 1, the clamping cylinder 22 controls the two lamp housing clamps 23 to clamp relative to each other, so that the outer wall of the lamp housing 1 is clamped and fixed by the two lamp housing clamps 23, thereby ensuring the positional accuracy of the lamp housing 1 and avoiding the problem of the lamp housing 1 moving during bending operations. The clamping cylinder 22 is a Y-type pneumatic finger cylinder. Two lamp housing clamps 23 are respectively mounted on the two jaws of the clamping cylinder 22. The operation of unfolding and clamping the lamp housing clamps 23 is simple and convenient, and the jaws can achieve a maximum unfolding of 180° without affecting the normal conveyor belt transport of products. The inner side of the lamp housing clamp 23 has an arc-shaped structure, the curvature of which matches the curvature of the area to be clamped on the lamp housing 1. When clamping the lamp housing 1, it can form a ring-shaped clamping fixation, resulting in better stability. Especially when the clamping point of the lamp housing clamp 23 is at the screw thread position of the lamp housing 1, it can achieve full clamping with a smaller area.
[0020] A further improvement is made to the positioning device 3, which includes two symmetrically arranged wire clamps 31. The two wire clamps 31 are respectively disposed on the two lamp housing clamps 23 and controlled by the clamping cylinder 22. The gap between the two wire clamps 31 in the clamping state of the clamping cylinder 22 is located in the middle of the screw opening of the lamp housing 1.
[0021] The cable clamp 31 consists of two sheet-like plates. The cable clamp 31 is directly mounted on top of the sheet-like lamp housing clamp 23, with a close-fitting connection between the two. This connection method is simple, provides good stability after installation, and eliminates the need for additional driving force to drive the cable clamp 31, resulting in higher control costs and better synchronization. When the jaws are closed, the two cable clamps 31 form a gap slightly wider than the outer diameter of the power cord 4, with a maximum gap not exceeding twice the outer diameter of the power cord 4. During clamping, the gap between the two cable clamps 31, clamped by the clamping cylinder 22, is located in the middle of the housing. This ensures that both long and short power cords 4 are in the middle position, allowing for simultaneous clamping and repositioning of the power cord 4, preventing the power cord 4 from being unable to be gripped when bent.
[0022] Based on the above technical solution, the bending device 5 is further improved as follows: the bending device 5 includes a second fixed rod 55, a lifting cylinder 54 disposed on the second fixed rod 55, and a bending cylinder 53 disposed on the lifting cylinder 54. The piston rod of the lifting cylinder 54 is provided with a right-angle push block 51, the top of the right-angle push block 51 is provided with a pressing cylinder 52, the piston rod of the pressing cylinder 52 is provided with a bending slider 56, and the bending slider 56 is located inside the right-angle push block 51.
[0023] The bending device 5 is generally installed on the other side of the conveyor line via the second fixed rod 55. The lifting cylinder 54 is vertically installed on the second fixed rod 55 and is used to control the bending cylinder 53 and the right-angle push block 51 up and down. When it is necessary to bend the edge of the clamped lamp housing 1, the bending cylinder 53 first controls the right-angle push block 51 to extend forward, pushing the long power line apart to form a gap with the short power line. Then, the retraction of the upper and lower cylinders 54 drives the right-angle push block 51 to descend. At this time, the right-angle push block 51 is positioned between the long and short power lines. Then, the bending cylinder 53 retracts, simultaneously bending the short power line outward for the first time. Next, the pressing cylinder 52 extends, driving the bending slider 56 to press down, bending the edge line that has already been bent once again. This realizes the function of automatically bending the edge line. The bending operation of the power line 4 is simple, convenient, and easy to implement.
[0024] A further improvement is made in that the curved slider 56 has a right-angle structure, and the curved slider 56 in the retracted state is located inside the right-angle push block 51; the inner side of the right-angle push block 51 is provided with two limiting blocks 57, and a groove is formed between the right-angle push block 51 and the limiting blocks 57, and the curved slider 56 slides in the groove.
[0025] The bending slider 56 adopts a right-angle structure, which, after assembly, is similar to the structure of the right-angle push block 51, allowing them to form a tight stack after installation. During the second bend, the right-angle push block 51 can press the top of the lamp housing 1 firmly, while ensuring that the short power line 4 of the second bend is connected to the screw hole of the lamp housing 1 in an n-shape. Two limiting blocks 57 are installed on the inner side of the right-angle push block 51, forming a groove between the right-angle push block 51 and the limiting blocks 57. This allows the bending slider 56 to slide within the groove, preventing wobbling when the bending slider 56 moves up and down or presses the line.
[0026] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
