Technical Field

[0001] The present invention belongs to the technical field of connection by press fit equipment, and particularly relates to a wire pressing device for LED strip processing. Background Art

[0002] Under the background of the rapid development of LED lighting technology, LED strips are widely used in many fields such as decorative lighting, advertising signs, and automotive lighting due to their advantages of high brightness, low energy consumption, and long lifespan. In the processing and production process of LED strips, a wire pressing device is an indispensable key equipment, whose function is to press the lamp wire into the lamp tube sleeve. In the prior art, the patent with the publication number CN215589041U discloses a wire pressing device for an LED strip processing equipment, including a workbench and support legs. At both ends of the two sides at the bottom of the workbench, a group of support legs are respectively fixedly connected, and a top box is fixedly connected to the top of the workbench. This wire pressing device for the LED strip processing equipment is provided with a servo motor. The lamp wire is placed at the top of the lamp tube sleeve. The first cylinder at the top is started to drive the first telescopic rod to extend. The first telescopic rod drives the wire pressing wheel to press one side of the lamp wire into the inside of the sleeve. Then the servo motor at the top is started to drive the threaded shaft to rotate. While the threaded shaft rotates, it drives the external threaded sleeve to move to one side. The threaded sleeve then drives the first cylinder at the bottom to move to one side through the connecting sleeve plate, thereby driving the wire pressing wheel to slide to one side and pressing the whole lamp wire into the sleeve. The sliding rod limits the whole wire pressing mechanism through the connecting sleeve plate to ensure the stability of wire pressing, and solves the problem of being unable to automatically and quickly press the strip completely.

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

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

[0029] Embodiment 1

[0030] As Figures 1 to 6 shown, a wire pressing device for LED light strip processing provided by an embodiment of the present invention includes a workbench 1, a fixed frame 4 is fixedly installed on the workbench 1, a lifting mechanism 3 is arranged on the fixed frame 4, a wire pressing mechanism 2 is arranged on the lifting mechanism 3, a wire pressing wheel 6 is rotatably installed at the lower end of the wire pressing mechanism 2, a pneumatic finger 5 is fixedly installed on the lower surface of the workbench 1, and a clamping plate 51 is fixedly connected to the pneumatic finger 5.

[0031] Furthermore, a movable block 52 is fixedly connected to the lower surface of the clamping plate 51, 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, clamping plates 51 are fixedly connected to both clamping jaws of the pneumatic finger 5, the two clamping plates 51 are L-shaped and symmetrically arranged, the lamp tube sleeve is placed between the two clamping plates 51, movable blocks 52 are fixedly connected to the bottoms of both ends of the two clamping plates 51, and when the clamping plate 51 moves under the drive of the pneumatic finger 5, the movable block 52 slides along the fixed rod 53, playing a role in limiting the clamping plate 51 to ensure that the two clamping plates 51 move in parallel and guarantee the stable clamping of the lamp tube sleeve.

[0033] Furthermore, the lifting mechanism 3 includes a fixed box 31, the fixed box 31 is fixedly installed at the middle upper end of the fixed frame 4, a motor 32 is fixedly installed at the upper end of the fixed box 31, a screw 33 is rotatably installed inside the fixed box 31, a screw rod seat 34 is threadedly connected to the screw 33, and the screw rod 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 bottoms of the two sets 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. By starting the motor 32 to drive the screw 33 to rotate, the lead screw seat 34 is driven to slide along the inner wall of the fixed box 31, so as to drive the fixed shaft 23 to move synchronously.

[0035] Further, the wire pressing mechanism 2 includes a fixed shaft 23, the fixed shaft 23 is fixedly installed on one side of the lead screw seat 34, two sets of support frames 22 are rotatably installed on the fixed shaft 23, the bottom of each set of support frames 22 is rotatably installed on the mounting frame 21, and one side of the mounting frame 21 is fixedly connected with a sliding sleeve 24, the sliding sleeve 24 is slidably connected to the sliding rod 25, and both ends of the sliding rod 25 are slidably connected to the side walls at both ends of the fixed frame 4 (it can move up and down within a certain range).

[0036] In this application, the upper and lower ends of the support frame 22 are respectively rotatably connected to the fixed shaft 23 and the mounting frame 21. 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 bottom gradually opens, so that the two mounting frames 21 gradually move towards both ends of the lamp wire tube sleeve. By providing a sliding sleeve 24 on one side of the mounting frame 21 that slides along the sliding rod 25, it can ensure the horizontal movement of the mounting frame 21, realize the quick operation of pressing the lamp wire from the middle to both sides, and improve the efficiency of wire pressing. It should be noted that since the sliding rod 25 is horizontally arranged, the inclination degrees of the two sets of support frames 22 can be the same (in opposite directions), so that the two sets of mounting frames 21 move in opposite directions at equal distances.

[0037] An installation rod 26 is fixedly connected inside the mounting frame 21, the wire pressing wheel 6 is rotatably installed in the middle of the installation rod 26, and the wire pressing wheel 6 is installed in the mounting frame 21 through the installation rod 26. During the working process, the wire pressing wheel 6 first moves down synchronously with the fixed shaft 23 and the mounting frame 21, and then presses on the lamp wire. After pressing the lamp wire into the lamp wire tube sleeve, the wire pressing wheel 6 no longer moves down. As the fixed shaft 23 moves down, the wire pressing wheel 6 rolls along the lamp wire and the lamp wire tube sleeve, and the lower ends of the support frames 22 gradually open outwards, and the mounting frame 21 moves outwards. This design is more efficient than the traditional single-side pressing. Both ends of the installation rod 26 are sleeved with a movable plate 28 and a spring 27. The movable plate 28 is slidably connected to the installation rod 26. Both 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 limiting rod 210. The limiting 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 clamping plate 51. A wire bundling shaft 29 is rotatably installed at the bottom of the movable plate 28.

[0038] The movable plate 28 is slidably connected to the mounting rod 26. As the mounting frame 21 moves downward, 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 in the direction close to the wire pressing wheel 6, driving the wire bundling shaft 29 to move synchronously, so that the wire bundling shaft 29 is close to the lamp wire and the lamp wire tube sleeve. The wire bundling shaft 29 is arranged in front of the advancing direction of the wire pressing wheel 6, which can effectively adjust the lamp wire and avoid the situation that the lamp wire is offset, resulting in misalignment of wire pressing or even damage to the lamp wire or the lamp wire tube sleeve. When the movable plate 28 moves, the spring 27 is stretched. 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 method is as follows:

[0040] Equipment installation and debugging: Before using the wire pressing device for LED light strip processing, first place the workbench 1 on a flat ground to ensure its stability without shaking. Place the lamp wire tube sleeve between the two L-shaped clamping plates 51, and adjust the pneumatic clamping fingers 5 so that it stably clamps the lamp wire tube sleeve through the clamping plates 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 rod 33 and the sliding of the screw rod seat 34 on the inner wall of the fixed box 31 to ensure that the wire pressing 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, the motor 32 drives the screw rod 33 to rotate, driving the screw rod seat 34 to slide downward along the inner wall of the fixed box 31, and then driving the fixed shaft 23 to move downward. As the fixed shaft 23 moves downward, the upper ends of the two support frames 22 rotate around the fixed shaft 23, and the bottom gradually opens, so that the two mounting frames 21 gradually move horizontally towards both ends of the lamp wire tube sleeve under the cooperation of the sliding sleeve 24 and the sliding rod 25. During this process, the wire pressing wheel 6 first moves downward synchronously with the fixed shaft 23 and the mounting frame 21. When the wire pressing wheel 6 contacts the lamp wire, it starts to press the lamp wire into the lamp wire tube sleeve. When the lamp wire is pressed into the lamp wire tube sleeve, the wire pressing wheel 6 no longer moves downward. As the fixed shaft 23 continues to move downward, the wire pressing wheel 6 rolls along the lamp wire and the lamp wire tube sleeve, the lower ends of the support frames 22 further open outward, and 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 body at the lower end of the movable plate 28 contacts the upper end of the clamping plate 51 and moves in the direction close to the wire pressing wheel 6, driving the wire bundling shaft 29 to move synchronously, so that the wire bundling shaft 29 is close to the lamp wire and the lamp wire tube sleeve, and adjusts the lamp wire to prevent the lamp wire from shifting.

[0042] Device reset: After the wire pressing operation is completed, reverse-start the motor 32 to rotate the screw 33 in the reverse direction, driving the lead screw seat 34 to move upward, and then raising the wire pressing mechanism 2 to 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 are added to this device, such as position sensors and pressure sensors. 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 downward pressing position of the wire pressing wheel 6 to achieve precise control; the pressure sensor is installed on the wire pressing wheel 6 to monitor the pressure magnitude during the wire pressing process in real time. When the pressure exceeds the set value, the downward pressing action is automatically stopped to avoid damaging the lamp wire or the lamp wire tube sleeve due to excessive pressure, further improving the safety and reliability of the device.

[0044] Embodiment 2

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

[0046] Residue during processing: First, when the lamp wire is combined with the lamp wire tube sleeve, if glue is used for fixation (such as waterproof glue, thermal conductive glue), it may cause glue to stick to the surface of the wire pressing wheel due to excessive application or extrusion and overflow. Second, dust, metal debris (such as residues after cutting) on the surface of the lamp wire or particles generated by the wear of the insulating layer will gradually adhere during the wire pressing and rolling process.

[0047] Environmental factors: If the air in the processing workshop contains pollutants such as dust and oil stains, they may deposit on the surface of the wire pressing wheel during the operation of the equipment.

[0048] Material characteristics: Some lamp wire tube sleeves or lamp wire surfaces may be coated with lubricants (for easy wire pressing). After the lubricant contacts the air, it may adsorb impurities to form dirt.

[0049] To solve the above problems, the following settings are made:

[0050] Refer to Figures 1 - 8, the movable plate 28 includes a vertical portion 281, an inclined portion 282, a bottom portion 283, and a scraping portion 284; a threaded hole is formed in the vertical portion 281, and a threaded sleeve 285 is threadedly connected in the threaded hole. The threaded 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 snap-fitted 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. The wire bundling shaft 29 is installed on the upper surface of the bottom portion 283; the scraping portion 284 is fixedly connected to the upper end of the vertical portion 281. When the two movable plates 28 approach each other, the scraping portion 284 fits against the upper edge of the wire pressing wheel 6 for cleaning, preventing impurities on the wire pressing wheel 6 from being pressed into the light strip or scraping off the glue on the wire pressing wheel 6.

[0051] The mounting rod 26 includes an end shaft 261, a bending portion 262, and a bearing shaft 263 that are connected in sequence; the end shaft 261 is fixedly connected to the mounting frame 21, the bending portion 262 bends 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 bending portion 262 and the end shaft 261 is an arc structure, the connection between the bending portion 262 and the bearing shaft 263 is an arc structure, and the threaded sleeve 285 can move from the end shaft 261 to the bending portion 262.

[0052] When the threaded sleeve 285 slides to the bending portion 262, the threaded sleeve 285 bends and drives the entire movable plate 28 to tilt. On the one hand, the upper end of the wire bundling shaft 29 tilts towards the middle, and the lamp wire can be squeezed obliquely downward towards the middle, making it easier for the lamp wire to enter the pipe sleeve. And at the same time, the scraping portion 284 also tilts and fits more tightly against the wire pressing wheel 6, improving the ability to scrape off foreign objects. Further, when a cleaning layer 286 is provided in the middle of the lower side of the scraping portion 284, the cleaning layer 286 closely adheres to the wire pressing wheel 6, thereby cleaning the scraped impurities.

[0053] With this setting, by rotating the threaded sleeve 285 to adjust the position of the threaded sleeve 285, when the threaded sleeve 285 reaches the bending portion 262, the entire movable plate 28 can tilt, so that the degree of tilt can be adjusted.

[0054] The movable plate 28 is a key component in the wire pressing device, and realizes multi-dimensional adjustment functions through 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 socket connection with the mounting rod 26. Second, the upper end notch is clamped with the limiting rod 210 to ensure that the movable plate moves along a preset track. Third, it provides a connection basis for the inclined part 282, the bottom part 283 and the scraping part 284. The inclined part 282 is used to guide the movable plate 28 to generate a horizontal component force when moving in the vertical direction. The bottom part 283 is horizontally arranged to ensure the stability of the installation of the wire bundling shaft 29. The scraping part 284 is an arc design that fits the upper edge of the wire pressing wheel 6 (or at least when the movable plates 28 approach each other, the scraping part 284 can fit the upper edge of the wire pressing wheel 6), and a cleaning layer can be configured (it is recommended to use silica gel or soft rubber material).

[0055] The special shape design of the mounting rod 26 is the basis for realizing the inclination function of the movable plate 28: The fixed connection method of the end shaft 261 and the mounting frame 21 (using double fixation of threaded connection and positioning pins). The curvature radius of the arc transition structure of the bending part 262 needs to ensure smooth transition of the screw 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 stage:

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

[0060] The movable plate 28 remains vertical;

[0061] The wire bundling shaft 29 conducts preliminary guiding on the lamp wire;

[0062] The scraping part 284 keeps slight contact with the wire pressing wheel 6.

[0063] Inclination adjustment stage:

[0064] The screw sleeve 285 enters the area of the bending part 262;

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

[0066] The angle of the wire bundling shaft 29 changes, forming a squeezing force obliquely downward towards the middle;

[0067] The scraping part 284 fits more closely with the wire pressing wheel 6, and the cleaning ability is improved.

[0068] The working principle of the present invention:

[0069] During use, place the lamp tube sleeve between the two clamping plates 51. Start the pneumatic clamping fingers 5 to drive the two side clamping plates 51 to move inward, clamping and fixing the lamp tube sleeve. Press the middle part of the lamp wire into the middle part of the lamp 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 presses on the lamp tube sleeve, the upper end of the support frame 22 rotates around the fixed shaft 23 as the center, and the lower end opens. The wire pressing wheel 6 rolls along the lamp tube sleeve, gradually pressing the lamp wire into the lamp tube sleeve from the middle to both sides. During the downward movement of the mounting frame 21, 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 in the direction close to the wire pressing wheel 6, driving the wire bundling shaft 29 to move synchronously, so that the wire bundling shaft 29 is close to the lamp wire and the lamp tube sleeve. During the forward movement of the wire pressing wheel 6, the wire bundling shaft 29 can effectively adjust the lamp wire, avoiding the situation of wire pressing misalignment or even damage to the lamp wire or the lamp tube sleeve caused by the deviation of the lamp wire, and improving the processing quality.

[0070] In summary, for this wire pressing device for LED light strip processing, by setting two groups of support frames 22 and wire pressing wheels 6, which gradually move to both sides under the drive of the lifting mechanism 3, the lamp wire can be quickly pressed from the middle to both sides, improving the efficiency of wire pressing. By setting the wire bundling shaft 29 in front of the forward movement direction of the wire pressing wheel 6, and gradually approaching the lamp wire and the lamp tube sleeve as the movable plate 28 moves downward, the lamp wire can be effectively adjusted, avoiding the situation of wire pressing misalignment or even damage to the lamp wire or the lamp tube sleeve caused by the deviation of the lamp wire.
