DETAILED DESCRIPTION

[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0028] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figures 1 to 6 As shown, an embodiment of the present invention provides a wire crimping device for processing LED light strips, comprising a workbench 1, a fixing frame 4 is fixedly mounted on the workbench 1, a lifting mechanism 3 is provided on the fixing frame 4, a wire crimping mechanism 2 is provided on the lifting mechanism 3, a wire crimping wheel 6 is rotatably mounted on the lower end of the wire crimping mechanism 2, a pneumatic clamping finger 5 is fixedly mounted on the lower surface of the workbench 1, and a splint 51 is fixedly connected to the pneumatic clamping finger 5.

[0031] Furthermore, a movable block 52 is fixedly connected to the lower surface of the clamping plate 51 , and the movable block 52 is slidably connected to a fixed rod 53 , and the fixed rod 53 is fixedly installed on the lower surface of the workbench 1 .

[0032] Specifically, the two grippers of the pneumatic clamping fingers 5 are fixedly connected with a clamping plate 51, the two clamping plates 51 are L-shaped and symmetrically arranged, the lamp line tube sleeve is placed between the two clamping plates 51, and the bottom of both ends of the two clamping plates 51 are fixedly connected with a movable block 52. When the clamping plate 51 moves under the drive of the pneumatic clamping fingers 5, the movable block 52 slides along the fixed rod 53, which limits the clamping plate 51, ensuring that the clamping plates 51 on both sides move in parallel, thereby ensuring stable clamping of the lamp line tube sleeve.

[0033] Furthermore, the lifting mechanism 3 includes a fixed box 31, which is fixedly installed in the middle of the upper end of the fixed frame 4. A motor 32 is fixedly installed on the upper end of the fixed box 31. A screw 33 is rotatably installed inside the fixed box 31. A screw seat 34 is threadedly connected to the screw 33, and the screw seat 34 is slidably connected to the inner wall of the fixed box 31.

[0034] Specifically, the lifting mechanism 3 is used to drive the wire pressing mechanism 2 to move up and down, so that the bottom of the two groups of support frames 22 of the wire pressing mechanism 2 are opened or closed, so that the two wire pressing wheels 6 move from the middle of the lamp wire to both sides at the same time, quickly pressing the lamp wire into the lamp wire tube sleeve, and driving the screw 33 to rotate by starting the motor 32, driving the screw seat 34 to slide along the inner wall of the fixed box 31, thereby driving the fixed shaft 23 to move synchronously.

[0035] Furthermore, the wire pressing mechanism 2 includes a fixed shaft 23, which is fixedly installed on one side of the screw seat 34. Two groups of support frames 22 are rotatably installed on the fixed shaft 23. The bottom of each group of support frames 22 is rotatably installed on the mounting frame 21. A sliding sleeve 24 is fixedly connected to one side of the mounting frame 21. The sliding sleeve 24 is slidably connected to the sliding rod 25. The two ends of the sliding rod 25 are respectively slidably connected to the side walls of the fixed frame 4 (can move up and down within a certain range).

[0036] In this application, the upper and lower ends of the support frames 22 are rotatably connected to the fixed shaft 23 and the mounting frame 21, respectively. When the fixed shaft 23 moves downward, the upper ends of the two sets of support frames 22 rotate around the fixed shaft 23, and the bottoms gradually open, causing the two mounting frames 21 to gradually move toward the ends of the lamp line tube sleeve. By providing a sliding sleeve 24 that slides along a slide rod 25 on one side of the mounting frame 21, it is possible to ensure horizontal movement of the mounting frame 21, realizing a quick operation of pressing the lamp line from the center to the sides, thereby improving the efficiency of the wire pressing. It should be noted that because the slide rod 25 is set horizontally, the two sets of support frames 22 can be tilted to the same degree (in opposite directions), thereby causing the two sets of mounting frames 21 to move in opposite directions and at equal distances.

[0037] The mounting frame 21 is fixedly connected to a mounting rod 26, and the crimping wheel 6 is rotatably mounted on the middle of the mounting rod 26. The crimping wheel 6 is mounted in the mounting frame 21 through the mounting rod 26. During operation, the crimping wheel 6 first moves downward synchronously with the fixed shaft 23 and the mounting frame 21, and then presses on the lamp wire. After the lamp wire is pressed into the lamp wire tube sleeve, the crimping wheel 6 no longer moves downward. As the fixed shaft 23 moves downward, the crimping wheel 6 rolls along the lamp wire and the lamp wire tube sleeve, the lower end of the support frame 22 gradually opens outward, and the mounting frame 21 moves outward. Compared with the traditional single-sided press-in, this design is more efficient. Both ends of the mounting rod 26 are provided with a movable plate 28 and a spring 27. The movable plate 28 is slidably connected to the mounting rod 26. The two ends of the spring 27 are fixedly connected to the side wall of the mounting frame 21 and one side of the movable plate 28 respectively. The upper end of the movable plate 28 is slidably connected to the limit rod 210, and the limit rod 210 is fixedly installed inside the mounting frame 21. The lower end plate body of the movable plate 28 is inclined and slidably connected to the upper end of the splint 51. The bottom of the movable plate 28 is rotatably installed with a wire harness shaft 29.

[0038] The movable plate 28 is slidably connected to the mounting rod 26. As the mounting frame 21 moves downward, the inclined plate at the lower end of the movable plate 28 contacts the upper end of the clamping plate 51 and gradually moves toward the direction close to the wire pressing wheel 6, driving the wire tie shaft 29 to move synchronously, so that the wire tie shaft 29 is close to the lamp wire and the lamp wire tube sleeve. The wire tie shaft 29 is set in front of the forward direction of the wire pressing wheel 6, which can effectively adjust the lamp wire to avoid the situation where the lamp wire is offset and the wire pressing is misplaced or even damaged. When the movable plate 28 moves, the spring 27 is stretched and lengthened. After the wire pressing is completed, the lifting mechanism 3 drives the wire pressing mechanism 2 to reset. The movable plate 28 gradually moves upward and resets under the elastic force of the spring 27, which is convenient for the next operation.

[0039] The specific implementation methods are as follows:

[0040] Equipment installation and debugging: Before using the wire crimping device for processing LED light strips, first place the workbench 1 on a stable ground to ensure that it is stable and does not shake. Place the lamp wire tube sleeve between the two L-shaped clamps 51, and adjust the pneumatic clamping fingers 5 so that they can stably clamp the lamp wire tube sleeve through the clamps 51. Check whether the sliding connection between the movable block 52 and the fixed rod 53 is smooth to avoid affecting the clamping effect due to jamming. Debug the lifting mechanism 3, start the motor 32, observe the rotation of the screw 33 and the sliding of the screw seat 34 on the inner wall of the fixed box 31, and ensure that the wire crimping mechanism 2 can be lifted and lowered normally. At the same time, check the sliding connection between the sliding sleeve 24 and the sliding rod 25 to ensure that the mounting frame 21 moves smoothly in the horizontal direction.

[0041] Lamp wire pressing operation: Place the lamp wire to be processed above the lamp wire tube sleeve, start the motor 32, and the motor 32 drives the screw 33 to rotate, driving the screw seat 34 to slide downward along the inner wall of the fixed box 31, thereby driving the fixed shaft 23 to move downward. As the fixed shaft 23 moves downward, the upper ends of the two sets of support frames 22 rotate around the fixed shaft 23, and the bottom gradually opens, so that the two mounting frames 21 gradually move horizontally toward the two ends of the lamp wire tube sleeve with the cooperation of the sliding sleeve 24 and the sliding rod 25. During this process, the pressing wheel 6 first moves downward synchronously with the fixed shaft 23 and the mounting frame 21. When the pressing wheel 6 contacts the lamp wire, it begins to press the lamp wire into the lamp wire tube sleeve. After the lamp wire is pressed into the lamp wire tube sleeve, the pressing wheel 6 no longer moves downward. As the fixed shaft 23 continues to move downward, the pressing wheel 6 rolls along the lamp wire and the lamp wire tube sleeve, and the lower end of the support frame 22 further opens outward. The mounting frame 21 continues to move outward until the lamp wire is completely pressed into the lamp wire tube sleeve from the middle of the lamp wire to both sides. During the downward movement of the mounting frame 21, the inclined plate at the lower end of the movable plate 28 contacts the upper end of the clamping plate 51 and moves toward the direction close to the wire pressing wheel 6, driving the wire bundle shaft 29 to move synchronously, so that the wire bundle shaft 29 is close to the lamp wire and the lamp wire tube sleeve, adjusting the lamp wire to prevent the lamp wire from deviating.

[0042] Equipment reset: After the wire pressing operation is completed, the motor 32 is started in the reverse direction, causing the screw 33 to rotate in the reverse direction, driving the screw seat 34 to move upward, and then the wire pressing mechanism 2 is raised and reset. During the reset process, the movable plate 28 gradually moves upward and returns to its initial position under the elastic force of the spring 27, waiting for the next wire pressing operation.

[0043] Furthermore, sensors such as position sensors and pressure sensors are added to the device. The position sensor is used to monitor the clamping position of the clamping plate 51, the moving position of the mounting bracket 21, and the pressing position of the wire crimping wheel 6, achieving precise control. The pressure sensor is installed on the wire crimping wheel 6 to monitor the pressure during the crimping process in real time. When the pressure exceeds the set value, the pressing action is automatically stopped to avoid damage to the lamp wire or lamp wire sleeve due to excessive pressure, further improving the safety and reliability of the device.

[0044] Example 2

[0045] During the processing, impurities or glue may adhere to the crimping wheel 6. The main reasons include:

[0046] Process residue: First, when the lamp cable is attached to the cable sleeve, if glue (such as waterproof glue or thermal adhesive) is used, excessive application or overflow from squeezing may cause the glue to stick to the crimping roller surface. Second, dust, metal debris (such as residue from cutting), or particles from insulation wear on the lamp cable surface can gradually adhere to the crimping roller during the crimping process.

[0047] Environmental factors: If the air in the processing workshop contains pollutants such as dust and oil, they may be deposited on the surface of the crimping wheel when the equipment is running.

[0048] Material characteristics: Some lamp cord sleeves or lamp cord surfaces may be coated with lubricant (to facilitate crimping). When the lubricant comes into contact with air, it may absorb impurities and form dirt.

[0049] To solve the above problem, make the following settings:

[0050] See Figures 1-8The movable plate 28 includes a vertical portion 281, an inclined portion 282, a bottom portion 283, and a scraper portion 284; a threaded hole is provided on the vertical portion 281, a screw sleeve 285 is threadedly connected to the threaded hole, and the screw sleeve 285 is slidably sleeved on the mounting rod 26; a notch is provided at the upper end of the vertical portion 281, and the notch is clamped to the limiting rod 210; the inclined portion 282 is fixedly connected to the lower end of the vertical portion 281; the bottom portion 283 is fixedly connected to the lower end of the vertical portion 281, and the bottom portion 283 is horizontally arranged, and the wire bundle shaft 29 is installed on the upper surface of the bottom portion 283; the scraper portion 284 is fixedly connected to the upper end of the vertical portion 281. When the two movable plates 28 are close to each other, the scraper portion 284 is attached to the upper edge of the wire pressing wheel 6 for cleaning. This prevents impurities on the wire pressing wheel 6 from being pressed into the light bar or scraping off the glue on the wire pressing wheel 6.

[0051] The mounting rod 26 includes an end shaft 261, a curved portion 262, and a bearing shaft 263 connected in sequence; the end shaft 261 is fixedly connected to the mounting frame 21, the curved portion 262 is bent downward, and the bearing shaft 263 is used to bear the wire pressing wheel 6; the end shaft 261 and the bearing shaft 263 are parallel, and the end shaft 261 is higher than the bearing shaft 263; the connection between the curved portion 262 and the end shaft 261 is an arc structure, and the connection between the curved portion 262 and the bearing shaft 263 is an arc structure, and the screw sleeve 285 can be moved from the end shaft 261 to the curved portion 262.

[0052] When the screw sleeve 285 slides to the curved portion 262, the screw sleeve 285 bends and causes the entire movable plate 28 to tilt. On the one hand, the upper end of the wire bundle shaft 29 tilts toward the middle, which can squeeze the lamp wire toward the middle and downward, making it easier for the lamp wire to enter the sleeve. At the same time, the scraper portion 284 also tilts, fitting more tightly with the wire pressing wheel 6, improving the ability to scrape away foreign matter. Furthermore, when a cleaning layer 286 is provided in the middle of the lower side of the scraper portion 284, the cleaning layer 286 is in close contact with the wire pressing wheel 6, thereby cleaning away the scraped impurities.

[0053] With this arrangement, the position of the screw sleeve 285 is adjusted by rotating the screw sleeve 285 . When the screw sleeve 285 reaches the curved portion 262 , the entire movable plate 28 can be tilted, thereby adjusting the degree of tilt.

[0054] The movable plate 28 is a key component in the wire pressing device, and a multi-dimensional adjustment function is achieved through a special design: the functions of the vertical part 281 are as follows: First, a threaded hole is opened and a screw sleeve 285 is installed to achieve a sliding connection with the mounting rod 26. Second, the upper end notch is engaged with the limit rod 210 to ensure that the movable plate moves along the preset trajectory. Third, a connection basis is provided with the inclined part 282, the bottom 283 and the scraper part 284. The inclined part 282 is used to guide the movable plate 28 to generate a horizontal component of force when moving in the vertical direction. The bottom 283 is set horizontally to ensure the stability of the installation of the wire bundle shaft 29. The scraper part 284 is an arc-shaped design that fits the upper edge of the wire pressing wheel 6 (or at least when the movable plates 28 are close to each other, the scraper part 284 can fit the upper edge of the wire pressing wheel 6), and a cleaning layer can be configured (silicone or soft rubber material is recommended).

[0055] The special shape of the mounting rod 26 is the basis for the tilting function of the movable plate 28: the fixed connection between the end shaft 261 and the mounting bracket 21 (using a dual fixation of threaded connection and positioning pins). The curvature radius of the arc transition structure of the curved portion 262 must ensure a smooth transition of the threaded sleeve 285.

[0056] The specific working principle of this embodiment is as follows:

[0057] When the screw sleeve 285 moves on the mounting rod 26:

[0058] Horizontal movement phase:

[0059] The screw sleeve 285 is located in the area of ​​the end shaft 261;

[0060] The movable plate 28 remains in a vertical state;

[0061] The wire harness shaft 29 provides preliminary guidance for the lamp wire;

[0062] The scraper portion 284 maintains slight contact with the pressing wheel 6.

[0063] Tilt adjustment stage:

[0064] The screw sleeve 285 enters the curved portion 262 area;

[0065] The movable plate 28 tilts around the limiting rod 210;

[0066] The angle of the bundle axis 29 changes, forming an extrusion force diagonally downward in the middle;

[0067] The scraper portion 284 fits more closely with the crimping wheel 6, thereby improving the cleaning capability.

[0068] Working principle of the present invention:

[0069] When in use, place the lamp wire tube sleeve between the two clamping plates 51, start the pneumatic clamping fingers 5 to drive the clamping plates 51 on both sides to move inward, clamp the lamp wire tube sleeve, press the middle of the lamp wire into the middle of the lamp wire tube sleeve, then start the motor 32 to drive the fixed shaft 23 and the wire pressing wheel 6 to move downward, when the wire pressing wheel 6 is pressed on the lamp wire tube sleeve, the upper end of the support frame 22 rotates with the fixed shaft 23 as the center, and the lower end opens, and the wire pressing wheel 6 rolls along the lamp wire tube sleeve, gradually pressing the lamp wire into the lamp wire tube sleeve from the middle to both sides, and moves under the mounting frame 21 During the process, the sliding sleeve 24 drives the sliding rod 25 to slide downward along the two side walls of the fixed frame 4, and the movable plate 28 moves downward synchronously. The inclined plate body at the lower end of the movable plate 28 contacts the upper end of the clamping plate 51 and gradually moves toward the direction close to the wire pressing wheel 6, driving the wire bundle shaft 29 to move synchronously, so that the wire bundle shaft 29 is close to the lamp wire and the lamp wire tube sleeve. During the forward movement of the wire pressing wheel 6, the wire bundle shaft 29 can effectively adjust the lamp wire to avoid the situation where the lamp wire is offset and the wire pressing is misplaced or even damaged. The processing quality is improved.

[0070] To sum up: this kind of wire pressing device for processing LED light strips, by setting two groups of support frames 22 and wire pressing wheels 6, makes it gradually move to both sides under the drive of the lifting mechanism 3, and can quickly press the light wire from the middle to both sides, thereby improving the efficiency of wire pressing. By setting a wire bundle shaft 29 in front of the forward direction of the wire pressing wheel 6, as the movable plate 28 moves downward and gradually approaches the light wire and the light wire tube sleeve, the light wire can be effectively adjusted to avoid the situation where the light wire is offset, resulting in wire pressing dislocation or even damage to the light wire or the light wire tube sleeve.
