Description

Technical Field

[0001] This utility model relates to the field of LED bracket processing equipment technology, and in particular to a high-precision bending processing mechanism for LED brackets. Background Technology

[0002] With the increasing maturity of LED technology, LED products are widely used in outdoor lighting, enabling them to achieve both aesthetic appeal and effective illumination. Most LED chips are mounted within LED brackets. Currently, the manufacturing process of LED brackets often involves bending sheet metal using stamping. However, for thin or thick sheet metal LED brackets, the high stamping speed and short duration can lead to inaccurate bending angles (springback), material damage or breakage at the bending points, and especially when processing materials of varying thicknesses, it is difficult to accurately adjust the stamping pressure. This results in a lower yield rate for the produced LED brackets, frequently requiring rework and hindering production efficiency. Furthermore, the lack of real-time monitoring and adjustment mechanisms makes it difficult to maintain consistent bending quality throughout the production process.

[0003] Therefore, it is necessary to propose a high-precision bending processing mechanism for LED brackets to improve the yield rate of LED brackets during bending processing, thereby improving production efficiency. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a high-precision bending processing mechanism for LED brackets to improve the yield rate of LED brackets during bending processing, thereby increasing production efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a high-precision bending processing mechanism for LED brackets, including a pushing bending mechanism, a bonding and pressing mechanism, and a CCD vision inspection component. The pushing bending mechanism and the bonding and pressing mechanism form a mold connection. The pushing bending mechanism is provided with a material groove for placing the LED bracket. The bonding and pressing mechanism is provided with a clearance groove and a viewing groove. The clearance groove and the viewing groove are connected. The viewing groove is away from the material groove and aligned with the material groove. The CCD vision inspection component is adjustablely connected to the bonding and pressing mechanism and faces the viewing groove. When the pushing bending mechanism pushes and bends the LED bracket, the CCD vision inspection component can perform CCD vision inspection on the bent part of the LED bracket that bends from the clearance groove into the viewing groove.

[0007] Furthermore, the CCD vision inspection component includes an adjustment frame and a CCD camera. The CCD camera is fixedly connected to one end of the adjustment frame and faces the viewing slot. The other end of the adjustment frame forms an adjustable sliding connection with the fitting and pressing mechanism.

[0008] Furthermore, one end of the adjustment frame is provided with two sliding plates, and the fitting and pressing mechanism is provided with two sliding connecting parts. The two sliding plates correspond one-to-one with the two sliding connecting parts, and the sliding plates and the sliding connecting parts form an adjustable sliding connection.

[0009] Furthermore, the sliding connection includes a connecting square tube and a knob. The sliding plate is inserted into the connecting square tube and slidably connected to it. The knob is threaded to one side of the connecting square tube and abuts against the sliding plate.

[0010] Furthermore, the sliding plate has a scale on one side, and the pressing mechanism has an indicator mark facing the scale.

[0011] Furthermore, the CCD vision inspection component also includes a ring light, which is fixedly connected to the adjustment frame and located on the outer periphery of the CCD camera, with the ring light facing the viewing slot.

[0012] Furthermore, the pushing bending mechanism includes a die blank, at least one pushing component, and a fixed frame. The die blank is fixedly connected to one end of the fixed frame, one end of all the pushing components is fixedly connected to the fixed frame, and the other end of all the pushing components is slidably connected to the die blank. The material groove is located on the upper surface of the die blank.

[0013] Furthermore, the pushing component includes a stepper motor, a connecting frame, and two push rods. The stepper motor is fixedly connected to the fixed structure. One end of the connecting frame is connected to the rotating shaft of the stepper motor as a lead screw. The other end of the connecting frame is fixedly connected to one end of each of the two push rods. The other ends of the two push rods are slidably connected to the mold blank and aligned with the clearance groove.

[0014] Furthermore, the mold blank is provided with a through groove, which is connected to the material groove, and one end of the push rod is received in the through groove.

[0015] Furthermore, the bottom of the mold blank is provided with the same number of contact switches as the pushing components, and the contact switches are aligned with the connecting frame.

[0016] The beneficial effects of this utility model are:

[0017] This invention employs a push-bending mechanism and a pressing mechanism for mold cooperation. The LED bracket is placed and fixed in the material groove. Simultaneously, the push-bending mechanism clamps and pushes the LED bracket to bend it. While the push-bending mechanism is bending the LED bracket, a CCD vision inspection component can perform CCD vision inspection on the bent part of the LED bracket from the clearance groove into the viewing groove. If the bending is not in place, the push-bending mechanism continues to push to ensure that the pushing distance of the push-bending mechanism is in place and that the bent part of the LED bracket is completely bent at the preset angle, thereby improving the yield rate of bending processing. In summary, this high-precision bending processing mechanism for LED brackets can effectively improve the yield rate of LED brackets during bending processing, thereby improving production efficiency.

[0030] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0031] Please refer to Figures 1-7 This utility model proposes a high-precision bending processing mechanism for LED brackets, including a pushing bending mechanism 1, a bonding and pressing mechanism 2, and a CCD vision inspection component 3. The pushing bending mechanism 1, the bonding and pressing mechanism 2, and the CCD vision inspection component 3 are electrically connected to an external controller. Workers can issue corresponding operating commands to the pushing bending mechanism 1, the bonding and pressing mechanism 2, and the CCD vision inspection component 3 through the external controller to make them operate. The pushing bending mechanism 1 and the bonding and pressing mechanism 2 form a mold connection. The pushing bending mechanism 1 is provided with a material groove 11 for placing the LED bracket 4, and the bonding and pressing mechanism 2 is provided with an avoidance groove 21 and a viewing groove 22. The slot 21 is connected to the viewing slot 22. The viewing slot 22 is away from the material slot 11 and aligned with the material slot 11. The CCD vision inspection component 3 is adjustablely connected to the pressing mechanism 2 and faces the viewing slot 22. The image range acquired by the CCD vision inspection component 3 is the entire range of the viewing slot 22. When the bending mechanism 1 pushes the LED bracket 4 to bend, the CCD vision inspection component 3 can perform CCD vision inspection on the bent part 41 of the LED bracket 4 that bends from the clearance slot 21 into the viewing slot 22. At the same time, the CCD vision inspection component 3 can also increase the recognition conditions of mold damage or wear, which is beneficial for correcting or maintaining the mold when it is worn.

[0032] In this embodiment, the bending mechanism 1 is driven by a servo motor, and the thrust is dynamically adjusted according to the material thickness (e.g., the thrust is set to 50N±2N when the thickness is 0.2mm). The bending speed is reduced to 3-5mm / s to ensure that the material undergoes sufficient plastic deformation. The bending mechanism 1 is located below the bonding and pressing mechanism 2 and is pushed upwards. Alternatively, the bending mechanism 1 can be located above the bonding and pressing mechanism 2 and is pushed downwards. The CCD vision inspection component 3 is located at the top of the bonding and pressing mechanism 2. Before bending the LED bracket 4, the LED bracket 4 can be pre-bent at the part to be bent using an external pre-pressing device. If the LED bracket 4 is thin, pre-bending is not necessary. Then, the LED bracket 4 needs to be placed in the material tank 11. The bending mechanism 1 and the bonding and pressing mechanism 2 are then engaged in mold cooperation, so that the LED bracket 4 is clamped and fixed in the material tank 11. The bending mechanism 1 then pushes the LED bracket 4 to bend the preset part. When the LED bracket 4 is pushed and bent, its preset part is gradually pushed and bent into the clearance groove 21 by the pushing and bending mechanism 1, forming a bent part 41. The bent part 41 can be 30 to 90 degrees, and the specific degree range depends on the pushing and bending mechanism 1's push distance. The CCD vision inspection component 3 can perform CCD vision inspection on the bent part 41 of the LED bracket 4 from the clearance groove 21 into the viewing groove 22. The CCD vision inspection component 3 can detect the bending angle of the bent part 41 and the distance from the bending height, and then determine whether the bent part 41 is bent in place. For example, the CCD vision inspection component 3 determines the bending angle of the bent part 41 by recognizing the brightness ratio of the image of the bent part 41. If the bending is not in place, the pushing and bending mechanism 1 continues to push, or retreats a preset distance and then continues to push, to ensure that the pushing distance of the pushing and bending mechanism 1 is in place and the bent part 41 of the LED bracket 4 is completely bent at the preset angle, thereby improving the yield of the LED bracket 4 during bending processing.

[0033] The principle of CCD visual inspection of the bent part 41 of LED bracket 4 is as follows: First, the unbent LED bracket 4 is placed in the material tank 11. Then, the bending mechanism 1 is pushed to cooperate with the pressing mechanism 2 to form a mold. The bending mechanism 1 is also pushed into the relief groove 21. That is, the bending step is repeated once to ensure that the LED bracket 4 is completely bent. Then, the video is used as a comparison video and saved. At the same time, the image of the bent part 41 of LED bracket 4 is captured as a comparison image and saved. When performing subsequent bending processes, the comparison video and the comparison image are compared to determine whether the bending is qualified.

[0034] In summary, this high-precision bending processing mechanism for LED brackets can effectively improve the yield rate of LED brackets during bending processing, thereby increasing production efficiency.

[0035] In this embodiment, the CCD vision inspection component 3 includes an adjustment frame 31 and a CCD camera 32. The CCD camera 32 is fixedly connected to one end of the adjustment frame 31 and faces the viewing slot 22. The other end of the adjustment frame 31 forms an adjustable sliding connection with the bonding and pressing mechanism 2. The adjustment frame 31 is used to provide a stable support structure for the CCD camera 32. During installation, the bottom of the adjustment frame 31 is installed on the upper surface of the bonding and pressing mechanism 2. After installation, the adjustment frame 31 can be raised and lowered to manually adjust the image acquisition range of the CCD camera 32.

[0036] In this embodiment, one end of the adjustment frame 31 is provided with two sliding plates 311, and the pressing mechanism 2 is provided with two sliding connecting parts 23. The two sliding plates 311 correspond one-to-one with the two sliding connecting parts 23, and the sliding plates 311 and the sliding connecting parts 23 form an adjustable sliding connection. When installing the adjustment frame 31, the two sliding plates 311 are inserted into the two sliding connecting parts 23 respectively, which is convenient and quick. This allows the CCD vision inspection component 3 to be changed to different styles according to the position of the component to be inspected by CCD, which is convenient and quick.

[0037] In this embodiment, the sliding connection part 23 includes a connecting square tube 231 and a knob 232. The sliding plate 311 is inserted into the connecting square tube 231 and slidably connected to the connecting square tube 231. The knob 232 is threadedly connected to one side of the connecting square tube 231 and abuts against the sliding plate 311. After the sliding plate 311 is inserted into the connecting square tube 231, the height of the adjusting frame 31 can be adjusted. After the height of the adjusting frame 31 is adjusted to a suitable height, the knob 232 can be tightened so that the knob 232 abuts against the sliding plate 311 to fix the adjusting frame 31 at the adjusted height.

[0038] In this embodiment, a scale 3111 is provided on one side of the sliding plate 311, and an indicator 24 is provided on the pressing mechanism 2, with the indicator 24 facing the scale 3111. After the height of the adjusting frame 31 is properly adjusted, the scale 3111 can be used to determine whether the sliding plates 311 on both sides are at the same height, so as to level the CCD camera 32.

[0039] In this embodiment, the CCD visual inspection component 3 also includes a ring light 33, which is fixedly connected to the adjustment frame 31 and located on the outer periphery of the CCD camera 32. The ring light 33 faces the viewing slot 22 and is used to provide supplementary lighting to the viewing slot 22 to improve the clarity of the CCD visual inspection.

[0040] In this embodiment, the bending mechanism 1 includes a die blank 12, at least one pushing component 13, and a fixing frame 14. The die blank 12 is fixedly connected to one end of the fixing frame 14, one end of all pushing components 13 is fixedly connected to the fixing frame 14, and the other end of all pushing components 13 is slidably connected to the die blank 12. The material groove 11 is located on the upper surface of the die blank 12. The die blank 12 provides a stable placement structure for the LED bracket 4, so that when the LED bracket is pushed and bent, the die blank 12 can provide effective planar support for the parts that do not need to be bent. The fixing frame 14 provides a stable mounting structure for the pushing components 13 and the die blank 12, so that... The pushing component 13 pushes the LED bracket. When bending the LED bracket, the pushing component 13 extends towards the material tank 11 to push out the part of the LED bracket 4 that needs to be bent. The bending part 41 can be bent at 30 to 90 degrees. The specific degree range depends on the pushing distance of the pushing component 13. Since the pressing mechanism 2 presses the LED bracket, the part of the LED bracket 4 that needs to be bent will be pushed and bent around the wall of the avoidance groove 21 as the axis of rotation. Finally, the bent part 41 is received in the viewing groove 22. This bending process is acquired and detected by the CCD vision inspection component 3.

[0041] In this embodiment, the pushing component 13 includes a stepper motor 131, a connecting frame 132, and two push rods 133. The stepper motor 131 is fixedly connected to the fixed frame 14. One end of the connecting frame 132 is connected to the rotating shaft of the stepper motor 131 as a lead screw. The other end of the connecting frame 132 is fixedly connected to one end of each of the two push rods 133. The other ends of the two push rods 133 are slidably connected to the mold blank 12 and aligned with the clearance groove 21. When bending the LED bracket, the stepper motor 131 rotates forward at a preset speed, and the lead screw rotates forward at a preset speed, driving the connecting frame 131. 2. Push the two push rods 133 towards the material trough 11, thereby pushing the two push rods 133 towards the material trough 11. Finally, the two push rods 133 will push out the part of the LED bracket that needs to be bent from the material trough 11, so that it is bent. During this process, the pushing force is released slowly and will not cause damage to the bent part. After the bending is completed, the stepper motor 131 reverses and resets the connecting frame 132 and the two push rods 133. The bending part 41 can be bent at 30 to 90 degrees. The specific degree range depends on the pushing distance of the push rods 133 driven by the stepper motor 131.

[0042] In this embodiment, the mold blank 12 is provided with a through groove 121, which is connected to the material groove 11. One end of the push rod 133 is received in the through groove 121. The through groove 121 provides a sliding space for the push rod 133 and also provides a guiding space for the push rod 133 to push accurately toward the material groove 11.

[0043] In this embodiment, the bottom of the mold blank 12 is provided with the same number of contact switches 122 as the pushing components 13. The contact switches 122 correspond one-to-one with the pushing components 13. The contact switches 122 are electrically connected to an external controller and are aligned with the connecting frame 132. In order to ensure that the pushing components 13 can automatically stop when pushed to the end, the contact switches 122 are set to work together with the pushing components 13. The contact switches 122 are installed at the bottom of the mold blank 12. During the process of the stepper motor 131 driving the connecting frame 132 to push towards the material trough 11, the connecting frame 132 will move towards the contact switch 122. When the connecting frame 132 contacts the contact switch 122, it means that the push rod 133 has been aligned to the end, the stepper motor 131 does not need to perform forward rotation, and the pushing components 13 can be reset.

[0044] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
