Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the invention provides an LED lamp angle forming device. The LED lamp angle forming device in this embodiment includes a positioning device 2, which is used to position the product; wherein, as... Figure 5 As shown, product 5 in this embodiment includes a central block 51 and a strip-shaped flexible circuit board 52 (wherein, the dotted line portion in the figure represents the state of the flexible circuit board before it is formed). An LED light 53 is installed at each end of the flexible circuit board 52. The flexible circuit board extends from the outside of the first sidewall of the central block, around the bottom of the central block, to the second sidewall opposite to the first sidewall. The LED lights at both ends of the flexible circuit board are tilted away from the central block, with the tilt angle required to be between 15° and 35°. That is, the ends of the LED lights and the connected flexible circuit board are tilted together towards the outside of the central block at a certain angle. It should be noted that the LED light angle forming device in this embodiment is used to attach the flexible circuit board to both sides of the central block, and the LED lights are tilted outward at the required angle to form the product. In the unformed state of the product, the flexible circuit board is located on the bottom side of the central block and is in a flattened state. In this embodiment, to improve the accuracy of the LED light tilt angle and the consistency of the LED tilt angle after the product is formed, this embodiment makes specific settings for the LED light angle forming device.

[0044] Among them, such as Figure 1 and Figure 2 As shown, the positioning device 2 includes: a positioning worktable 21; a platform 22 disposed on the positioning worktable 21, the platform 22 having a positioning area for placing products on its top side, the products being fixed in the positioning area; and the platform 22 being movably mounted on the positioning worktable 21 along a first direction perpendicular to the platform surface. Specifically, the platform 22 can be supported on the positioning worktable 21 by multiple springs, and a lifting device can be provided connected to the platform 22 to drive the platform 22 to rise or fall along the first direction. The lifting device may include a cylinder assembly connected to the platform 22, using the cylinder to drive the platform 22 to rise or fall. For the platform 22, there is a rising station when the platform 22 rises to a certain position and a falling station when the platform 22 falls to a certain position.

[0045] The positioning device 2 also includes a first side push rod 23 and a second side push rod 24 disposed on the positioning worktable 21 and located on opposite sides of the platform 22. When the platform 22 is in the rising position, the table surface corresponds to and cooperates with the top surfaces of the first side push rod 23 and the second side push rod 24 to form a bearing surface for supporting the product. The unformed product can be placed on the bearing surface. The central block can be placed in the positioning area of ​​the platform 22 and can be fixed on the platform 22 and move up and down with the platform 22. The flexible circuit board is located on both sides of the central block, with a portion of one side resting on the top surface of the first side push rod 23 and a portion of the other side resting on the top surface of the second side push rod 24. The first side push rod 23 is located on the top surface of the platform 22. The first push rod 23 is movably mounted on the positioning worktable 21 in a second direction parallel to the table surface. The second push rod 24 is movably mounted on the positioning worktable 21 in the second direction and can also move in the second direction, so that the first push rod 23 and the second push rod 24 move in opposite directions or away from each other in the second direction. When the first push rod 23 and the second push rod 24 are located at the first station, both the first push rod 23 and the second push rod 24 are close to the platform 22 to apply clamping pressure to the product on the platform 22. When the first push rod 23 and the second push rod 24 are located at the second station, both the first push rod 23 and the second push rod 24 are away from the platform 22.

[0046] For the initial positioning of the product, the platform 22 is adjusted to the rising position, and the first side push rod 23 and the second side push rod 24 are adjusted to the second position. Both the first side push rod 23 and the second side push rod 24 are moved away from the platform 22 by a certain distance, but not by a large gap. This distance is relative to when they are in the first position. At this time, the platform surface mates with the top surfaces of the first side push rod 23 and the second side push rod 24 to form a support surface for the product. The unformed product can be placed on the support surface, and the center block can be placed in the positioning area of ​​the platform 22 and fixed in place. As the platform 22 moves up and down, the flexible circuit board is located on both sides of the central block. Part of one side rests on the top surface of the first push rod 23, and part of the other side rests on the top surface of the second push rod 24. After the unformed product is placed, the platform 22 is adjusted to move downwards, and the product moves downwards with the platform 22. The flexible circuit board resting on the first push rod 23 and the second push rod 24 is upright relative to the bottom of the central block. When the platform 22 descends to the lowering position, the flexible circuit board resting on the first push rod 23 is upright between the first push rod 23 and the platform 22. Within the spacing, the LED light at this end of the flexible circuit board is located above the top surface of the first push rod 23. The top surface of the first push rod 23 has a certain fitting shape to facilitate the subsequent pressing and forming angle of the LED light. Similarly, the flexible circuit board resting on the second push rod 24 is erected within the spacing between the second push rod 24 and the platform 22, and the LED light at this end of the flexible circuit board is located above the top surface of the second push rod 24. The top surface of the second push rod 24 has a certain fitting shape to facilitate the subsequent pressing and forming angle of the LED light. Then, the first push rod 23 and the second push rod 24 are adjusted to switch to the first working position. Both the first side push rod 23 and the second side push rod 24 are close to the product, and they work together to clamp the outer side of the product. Specifically, the flexible circuit boards located on both sides of the central block are pressed onto the central block, thus completing the positioning of the product before pressing. In the above positioning, the distance between the first side push rod and the second side push rod and the product can be adjusted so that the first side push rod and the second side push rod have a relatively accurate position at the first station. This allows the first side push rod and the second side push rod to position the product with high precision, resulting in higher product positioning accuracy. This is beneficial for subsequent pressing operations and can improve the consistency of the forming angle of the subsequently pressed products.

[0047] Therefore, the above-mentioned LED lamp angle forming device can position the product with high precision, so that the LED forming angle in the product is within the required range, and the forming angle of the formed product is relatively consistent.

[0048] like Figure 1 and Figure 4As shown, regarding the positioning of the aforementioned product, in order to improve the positioning accuracy of the first side push rod 23 and the second side push rod 24 at the first station, this can be achieved by accurately measuring the distance between the first station of the first side push rod 23 and the second side push rod 24 and the product. Therefore, a first limiting mechanism 25 can be set. The first limiting mechanism 25 includes: a first limiting structure for limiting the distance of the first side push rod 23 from the product to limit the clamping pressure of the first side push rod 23 on the product; and a first fine-tuning device 255 for adjusting the limiting accuracy of the first limiting structure. The first fine-tuning device 255 can adjust the position of the first station of the first side push rod 23 relative to the product with high precision and adjust the limiting of the first limiting structure. The position is such that the first side push rod 23 has a suitable pressing distance on the product when it is in the first station; similarly, a second limiting mechanism 26 is provided, which includes: a second limiting structure for limiting the distance of the second side push rod 24 from the product to limit the clamping pressure of the second side push rod 24 on the product, and a second fine-tuning device 265 for adjusting the limiting accuracy of the second limiting structure; the second fine-tuning device 265 can adjust the position of the first station of the second side push rod 24 relative to the product with high precision, and adjust the limiting position of the second limiting structure so that the pressing distance of the second side push rod 24 on the product is suitable when it is in the first station, ensuring that the tilt angle of the LED is within the required angle when the pressure rod assembly 31 presses the LED;

[0049] For the movement of the first side push rod 23, the first side push rod 23 can be mounted on the positioning worktable 21 via a guide rail extending along the second direction, and a first drive device is provided that is pulsatorically connected to the first side push rod 23 and used to drive the first side push rod 23 to move. For the second side push rod 24, the second side push rod 24 can be mounted on the positioning worktable 21 via a guide rail extending along the second direction, and a second drive device is provided that is pulsatorically connected to the second side push rod 24 and used to drive the second side push rod 24 to move. As can be seen from the above, the first fine-tuning device and the second fine-tuning device can perform high-precision adjustments, which can further improve the positional accuracy of the first side push rod and the second side push rod relative to the product at the first station, that is, to further improve the product positioning accuracy, which is beneficial to the subsequent pressing operation, so that the forming angle of the subsequently pressed product is more consistent, and the adjustment method of the first side push rod and the second side push rod is simple and reliable, the overall structure is simple, and it is easy to set up.

[0050] The aforementioned LED lamp angle forming device also includes a pressure rod mechanism 3, which corresponds to the positioning device 2 and works with the positioning device 2 to press the product to form the product. The pressure rod mechanism and the positioning device can be installed on a main worktable. After the product is positioned, the pressure rod mechanism 3 is used to press and form the LED lamp on the product. Specifically, the pressure rod mechanism 3 includes: a pressure rod assembly 31 located on the side of the table surface of the carrier 22 away from the positioning worktable 21 and used to press and form the product; and a third driving device for driving the pressure rod assembly 31 to move in a direction perpendicular to the table surface of the carrier 22. Under the drive of the third driving device, the pressure rod assembly 31 can press the LED on the product, causing the LED lamp to tilt outward at a certain angle relative to the central block. Due to the high positioning accuracy, the tilt angle of the LED is within the required range. And when the first station position of the first side push rod 23 and the second side push rod 24 is determined by high-precision micro-adjustment, the forming angle of the product formed by pressing and forming using this LED lamp angle forming device is highly consistent.

[0051] Specifically, in combination Figure 1 ,like Figure 3 As shown, in the above-mentioned LED lamp angle forming device, the first limiting mechanism 25 includes: a first limiting member 251, a first support 253, and a first limiting rod 254 installed on the first support 253 and cooperating with the first limiting member 251. The first limiting member 251 is fixed to the positioning worktable 21 and is located on the side of the platform 22 away from the second side push rod 24. The surface of the first limiting member 251 on the side away from the platform 22 forms a first limiting surface 252. The first support 253 is fixed to the first side push rod 23. The first limiting rod 254 is adjustablely installed on the first support 253 along the second direction and is used to cooperate with the first limiting surface 252 to limit the position of the first side push rod 23 at the first station. The structure is simple and the device can stably limit the position.

[0052] Combination Figure 1 ,like Figure 2 and Figure 4 As shown, the second limiting mechanism 26 includes: a second limiting member 261, a second support, and a second limiting rod 264 mounted on the second support 263 and cooperating with the second limiting member 261. The second limiting member 261 is fixed to the positioning worktable 21 and located on the side of the platform 22 away from the first side push rod 23. The surface of the second limiting member 261 on the side away from the platform 22 forms a second limiting surface 262. The second support 263 is fixed to the second side push rod 24. The second limiting rod 264 is adjustablely mounted on the second support 263 along the second direction and is used to cooperate with the second limiting surface 262 to limit the position of the second side push rod 24 at the first work station. The structure is simple and the device can be stably limited.

[0053] Specifically, in the aforementioned LED lamp angle forming device, the first fine-tuning device 255 may include a first micrometer. The frame of the first micrometer is used to be fixedly installed on the first support 253. The axis of the micrometer screw of the first micrometer is parallel to the second direction, and the measuring end face of the micrometer screw of the first micrometer is used to cooperate with the first limiting surface 252 to adjust the position of the first side push rod 23 at its first station. The micrometer can achieve micron-level adjustment, and the adjustment accuracy of the first side push rod 23 is extremely high, ensuring the consistency of the angle formed by the product. Moreover, the micrometer adjustment method is simple and reliable, ensuring high adjustment efficiency.

[0054] Specifically, the first micrometer is detachably connected to the first support 253. When the first micrometer is used to adjust the position of the first side push rod 23 at its first working position and the first limiting structure is adjusted to the limiting position, the first micrometer can be disassembled and stored. This is beneficial for maintaining the first micrometer, ensuring the adjustment accuracy of the first micrometer, and thus ensuring the adjustment accuracy when the first side push rod 23 is adjusted next time.

[0055] Specifically, in the aforementioned LED lamp angle forming device, the second fine-tuning device 265 includes a second micrometer. The frame of the second micrometer is fixedly mounted on the second support 263. The axis of the micrometer screw of the second micrometer is parallel to the second direction, and the measuring end face of the micrometer screw is used to cooperate with the second limiting surface 262. The micrometer can achieve micron-level adjustment, providing extremely high adjustment accuracy for the second side push rod 24, ensuring the consistency of the angle formed by the product. Furthermore, the micrometer adjustment method is simple and reliable, ensuring high adjustment efficiency.

[0056] Specifically, the second micrometer is detachably connected to the second support 263. When the second micrometer is used to adjust the position of the second side push rod 24 at its first working position and the second limiting structure is adjusted to the limiting position, the second micrometer can be disassembled and stored. This is beneficial for the maintenance of the second micrometer, ensuring the adjustment accuracy of the second micrometer, and thus ensuring the adjustment accuracy when adjusting the second side push rod 24 the next time the second micrometer is used.

[0057] Specifically, in the aforementioned first limiting structure, the first limiting rod 254 is a cylindrical limiting rod with an external thread on its outer circumferential surface. The axis of the first limiting rod 254 is parallel to the second direction. One end of the first limiting rod 254 is opposite to the first limiting surface 252 and can cooperate with the first limiting surface 252 to play a limiting role. The first support 253 is provided with a first threaded hole for the first limiting rod 254 to pass through and cooperate with the first limiting rod 254. The first limiting rod 254 and the first threaded hole are threadedly engaged, which has good stability and a simple and reliable adjustment method.

[0058] Specifically, in the aforementioned second limiting structure, the second limiting rod 264 is a cylindrical limiting rod with external threads on its outer circumferential surface. The axis of the second limiting rod 264 is parallel to the second direction. One end of the second limiting rod 264 is opposite to the second limiting surface 262 and can cooperate with the second limiting surface 262 to provide a limiting function. The second support 263 is provided with a second threaded hole for the second limiting rod 264 to pass through and cooperate with the second limiting rod 264. The first limiting rod 254 is threadedly engaged with the first threaded hole, providing good stability and a simple and reliable adjustment method.

[0059] Specifically, for the first and second limiting structures mentioned above, a limiting bracket can be fixedly installed on the positioning worktable 21. One side of the limiting bracket is located between the first support 253 and the platform 22, and this side faces the first support 253, thus forming the first limiting surface 252. The other side of the limiting bracket is located between the second support 263 and the platform 22, and this side faces the second support 263, thus forming the second limiting surface 262. The first limiting member 251 and the second limiting member 261 are formed on an integral structure. In addition, the first limiting member 251 and the second limiting member 261 can also be other structures, which are not limited in this embodiment.

[0060] Specifically, such as Figure 2 As shown, the pressure rod assembly 31 includes a first pressure rod 311 corresponding to the first side push rod 23 and a second pressure rod 312 corresponding to the second push rod. When the first side push rod 23 and the second side push rod 24 are located at the first working position, the free end of the first pressure rod 311 facing the first side push rod 23 cooperates with the top surface of the first side push rod 23 to press the LED on one side of the product, so that the LED tilts at a certain angle towards the outside of the central block. The free end of the second pressure rod 312 facing the second push rod cooperates with the top surface of the second side push rod 24 to press the LED on the other side of the product, so that the LED tilts at a certain angle towards the outside of the central block.

[0061] Specifically, corresponding to the mechanism of the aforementioned pressure rod assembly 31, the third driving device includes a first driving mechanism that is tractively connected to the first pressure rod 311 and drives the first pressure rod 311 to move up and down along the first direction; it also includes a second driving mechanism that is tractively connected to the second pressure rod 312 and drives the second pressure rod 312 to move up and down along the first direction.

[0062] Specifically, in the above-mentioned LED lamp angle forming device, the positioning worktable 21 of the positioning device 2 is movably installed on the main worktable 1 along a third direction that is parallel to the table surface of the platform 22 and perpendicular to the second direction; in the direction perpendicular to the table surface of the platform 22, the pressure rod assembly 31 corresponds to a part of the moving trajectory of the positioning device 2. When positioning the product, the positioning device 2 can be moved to a position away from the pressure rod assembly 31 to avoid the pressure rod assembly 31 from obstructing the placement of the product above the positioning device 2, as well as to adjust the accuracy of the positioning device 2. When the product positioning is completed, the positioning device 2 can be moved along the third direction to the position corresponding to the pressure rod assembly 31, and the product can be aligned with the pressure rod assembly 31. Then, the pressure rod assembly 31 can be moved to press and form the product.

[0063] Specifically, such as Figure 1 As shown, the aforementioned LED lamp angle forming device also includes an irradiation device 4 for irradiating the forming part of the product with ultraviolet light. Specifically, the irradiation device can be installed on the main workbench 1, and the irradiation device 4 includes an irradiation tube 41 with an opening opposite to the forming part of the product. Ultraviolet light can be emitted from the opening of the irradiation tube 41 through the irradiation tube and irradiate at least the forming part of the product, that is, the position where the LED lamp and flexible circuit board contact and bond with the side of the central block. This position is coated with UV adhesive. The ultraviolet light is directly transmitted to the side of the LED lamp and flexible circuit board bonded with the central block through the irradiation tube, providing sufficient ultraviolet light irradiation, which greatly reduces the rate of product delamination after bonding, even to below 0.1%. Specifically, the central block in the aforementioned product can be a lens barrel.

Therefore, if these modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
