Description

Technical Field

[0001] This utility model relates to a manufacturing equipment for LED strip products, specifically to a distance measuring device for processing LED strips with LED beads. Background Technology

[0002] The light strip includes a wire with LED beads mounted on it. The diameter of the LED beads is larger than that of the wire. During the injection molding and other post-processing of the light strip, the light strip needs to be continuously supplied, and the length of the supplied light strip needs to be set according to the needs. Therefore, it is necessary to measure the distance of the light strip during processing. At the same time, it is also necessary to avoid damaging the LED beads during the post-processing of the light strip. Utility Model Content

[0003] The main purpose of this utility model is to provide a distance measuring device for LED strip processing, so as to provide a distance measuring device that can measure the length of LED strips during LED strip processing.

[0004] This utility model provides a distance measuring device for LED strip processing. The LED strip includes a circuit and LED beads, the diameter of which is larger than the diameter of the circuit. The device includes a detection box containing an LED strip movement detector. The detector includes a fixed plate and a detection plate on one side of the fixed plate. The detection plate has a driving force to move towards the fixed plate. The LED strip passes through the gap between the detection plate and the fixed plate. When the LED beads are located in the gap between the detection plate and the fixed plate, they push the detection plate to move away from the fixed plate. A detection plate displacement sensor is provided on one side of the detection plate to detect the reciprocating motion of the detection plate.

[0005] Preferably, the displacement sensor of the detection piece is an electrical connection switch, and when the detection piece moves toward or away from the fixed plate, it forms a closed circuit with the electrical connection switch; the detector is also provided with a counter for counting the number of electrical connections.

[0006] Preferably, the displacement sensor of the detection piece is a distance sensor located at the rear of the detection piece, and the distance sensor detects the number of times the distance between the detection piece and the detection piece changes.

[0007] Preferably, the LED beads of the light strip are evenly distributed, and the displacement sensor of the detection sheet is also provided with a signal transmitter. The signal transmitter sends a control signal when it senses that the LED beads are located in the gap between the detection sheet and the fixing plate.

[0008] Preferably, the light strip is processed by mold processing, and the light beads should be avoided being located at the narrow diameter of the mold groove. When some of the light beads are located at the narrow diameter of the mold groove, the light beads remain in the gap between the detection plate and the fixing plate.

[0009] Preferably, a rubber block is provided at the rear of the mold groove, and when the LED bead is located at the corresponding position of the rubber block, the LED bead stays in the gap between the detection plate and the fixing plate.

[0010] Preferably, the detection piece is connected to a spring, and the spring drives the detection piece to move toward the fixed plate.

[0011] Preferably, the detection piece is an elastic piece, and the detection piece is close to the fixing plate.

[0012] Preferably, the front and rear sides of the detection plate are respectively provided with bending plates, and the bending plates extend at an angle away from the fixed plate.

[0013] Compared with the prior art, the luminous vine manufacturing equipment provided by this utility model has the following advantages:

[0014] In practical use, the aforementioned LED strip processing distance measuring device requires the LED strip to be pulled into subsequent processing devices such as injection molding. When the LED strip is supplied, it passes through the detection box and through the gap between the detection plate and the fixing plate. When the circuit of the LED strip passes through, the circuit diameter is small, and the detection plate moves towards the fixing plate under the action of driving force. When the LED beads pass through, due to the larger diameter of the LED beads, the LED beads will drive the detection plate away from the fixing plate. That is, the detection plate moves away from the fixing plate. The number of displacements of the detection plate can be detected by the detection plate displacement sensor, and then the number of LED beads passing through can be obtained. Since the LED beads in the LED strip are generally evenly distributed, the distance the LED strip has traveled can be obtained by counting the number of LED beads that have passed through.

[0015] When further processing of the LED strip is required, the LED strip moves toward the processing device as processing progresses. The detection box, as the path point of the LED strip, can detect the distance the LED strip travels, thereby providing data support for the supply of LED strips. Attached Figure Description

[0028] Example 1

[0029] This embodiment provides a light strip processing distance measuring device. The light strip includes a circuit 1 and LED beads 2. The circuit 1 generally consists of two wires, and the diameter of the LED beads 2 is larger than the diameter of the circuit 1. When further processing the light strip through injection molding or other processes, a continuous supply of light strips is required. The light strips are continuously fed into the light strip processing device via a light strip drive device through pulling or other means. However, during the input of the light strips, the distance of the input light strips needs to be detected and controlled. To achieve this detection and control, the light strip processing distance measuring device of this embodiment is provided. This device includes a detection box 3, which is located at the path of the light strip. A light strip movement detector is installed inside the detection box 3. The detector includes a fixed plate 4 and a detection piece 5 on one side of the fixed plate 4. The detection piece 5 has a driving force to move towards the fixed plate 4, that is, the detection piece 5 moves towards the fixed plate 4 under the action of elasticity or other driving forces. The light strip passes through the gap between the detection piece 5 and the fixing plate 4; when the LED bead 2 is located in the gap between the detection piece 5 and the fixing plate 4, it pushes the detection piece 5 to move away from the fixing plate 4. A displacement sensor for the detection piece 5 is provided on one side of the detection piece 5, and the displacement sensor for the detection piece 5 is used to detect the reciprocating motion of the detection piece 5.

[0030] In practical use, the aforementioned LED strip processing distance measuring device requires the LED strip to be pulled into subsequent processing devices such as injection molding. At this time, the LED strip passes through the detection box 3 and through the gap between the detection piece 5 and the fixing plate 4. When the circuit 1 of the LED strip passes through, the diameter of the circuit 1 is small, and the detection piece 5 moves closer to the fixing plate 4 under the action of driving force. When the LED bead 2 passes through, because the diameter of the LED bead 2 is larger, the LED bead 2 will drive the detection piece 5 away from the fixing plate 4. That is, the detection piece 5 moves away from the fixing plate 4. The displacement of the detection piece 5 can be detected by the displacement sensor of the detection piece 5, and then the number of LED beads 2 passing through can be obtained. Since the LED beads 2 in the LED strip are generally evenly distributed, the distance the LED strip passes through can be obtained by the number of LED beads 2 passing through. Meanwhile, the above-mentioned detection box 3 can also be configured such that when the lamp bead 2 is located in the gap between the detection piece 5 and the fixing plate 4, the lamp bead 2 at other positions of the light strip should be located or not located in a certain position: if the lamp bead 2 is not located in the gap between the detection piece 5 and the fixing plate 4, the lamp bead 2 is also not located in a position that is easily squeezed and damaged in the subsequent processing device of the light strip.

[0031] When further processing of the LED strip is required, the LED strip moves toward the processing device as processing progresses. The detection box 3, as the path point of the LED strip, can detect the distance the LED strip passes through, thereby providing data support for the supply of LED strips.

[0032] Specifically, in this embodiment, the displacement sensor of the detection piece 5 is an electrical connection switch. When the detection piece 5 moves toward or away from the fixed plate 4, it forms a closed circuit with the electrical connection switch. The detector is also equipped with a counter for counting the number of electrical connections. When the detection piece 5 moves closer to or away from the fixed plate 4, the electrical connection is opened or closed. The number of times the detection piece 5 moves is calculated by counting the number of electrical connections, thereby determining the number of LED beads 2 that have passed through.

[0033] Specifically, in this embodiment, the displacement sensor of the detection piece 5 is a distance sensor 6 located at the rear of the detection piece 5. The distance sensor 6 detects the number of distance changes between itself and the detection piece 5. The number of displacements of the detection piece 5, i.e., the number of LED beads 2 passing through, is obtained from the number of distance changes.

[0034] Specifically, in this embodiment, the LED beads 2 of the light strip are evenly distributed. The displacement sensor of the detection plate 5 is also equipped with a signal transmitter. The signal transmitter sends a control signal when it senses that the LED beads 2 are located in the gap between the detection plate 5 and the fixing plate 4. The above-mentioned light strip processing ranging device should be equipped with a controller. The controller receives the signal and processes the signal. After processing, it sends a signal to continue inputting the light strip or to stop inputting the light strip based on the processing result. Alternatively, when the light strip is located in the gap between the detection plate 5 and the fixing plate 4, the LED beads 2 in the light strip may be located in a position that is easily squeezed and damaged. The signal emitted by the signal transmitter can prevent the light strip processing device from entering the working state, such as stopping the injection molding. Of course, it can also be operated in reverse. For example, only when the LED beads 2 of the light strip are located in the gap between the detection plate 5 and the fixing plate 4, and the LED beads 2 of the light strip in the processing device are located in a preset position, will the processing device be started.

[0035] More specifically, in this embodiment, the LED strip processing is mold processing. The LED beads 2 should be avoided being located at the narrow diameter of the mold groove. When some of the LED beads 2 are located at the narrow diameter of the mold groove, the LED beads 2 will remain in the gap between the detection piece 5 and the fixing plate 4. That is, when the LED beads 2 are located in the gap between the detection piece 5 and the fixing plate 4, regardless of whether the LED beads 2 are located at the narrow diameter of the mold groove, if mold processing is performed at this time, the LED beads 2 will be damaged. Therefore, when the LED beads 2 are located in the gap between the detection piece 5 and the fixing plate 4, mold processing should be stopped. After the LED strip continues to move, a judgment on whether to perform mold processing should be made.

[0036] More specifically, in this embodiment, when injection molding is performed between molds, the front of the mold can be blocked by a section of the LED strip that has already been injection molded, while the rear of the mold only has two thin wires. To prevent the injection-molded thermoplastic material from being squeezed out from the rear, a rubber block is provided at the rear of the mold groove. Since the LED bead 2 has a large diameter and is relatively fragile, it is easily damaged by the rubber block. Therefore, when the LED bead 2 is at the corresponding position of the rubber block, the LED bead 2 stays in the gap between the detection piece 5 and the fixing plate 4. At this time, the signal emitted by the LED bead 2 at the gap between the detection piece 5 and the fixing plate 4 can be regarded as the LED bead 2 being located at the rear of the mold groove, thus leading to the judgment that mold processing is prohibited and processing should be carried out after the LED strip is adjusted, so as to avoid the rubber block damaging the LED bead 2.

[0037] More specifically, this embodiment also provides an implementation method for the driving force of the detection piece 5: the detection piece 5 is connected to a spring, and the spring drives the detection piece 5 to move towards the fixed plate 4.

[0038] More specifically, this embodiment also provides another implementation of the driving force of the detection piece 5: the detection piece 5 is an elastic piece, and the detection piece 5 is close to the fixing plate 4, that is, the detection piece 5 can elastically move towards the fixing plate 4.

[0039] Specifically, in this embodiment, to facilitate the entry and exit of the light strip into and out of the gap between the detection piece 5 and the fixing plate 4, bending plates 7 are respectively provided on the front and rear sides of the detection piece 5, and the bending plates 7 extend obliquely away from the fixing plate 4. Of course, it should be noted that the detection piece 5 can also be connected to a connecting plate 8 to install the detection piece 5 inside the detection box 3.

[0040] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
