Description

Technical Field

[0001] This utility model relates to the field of glass fiber warp tube processing technology, specifically to an automatic surface polishing device for glass fiber warp tubes. Background Technology

[0002] Fiberglass warp tubes are mostly produced using injection molding, which inevitably creates parting lines on the surface of the tube after molding. If these parting lines are not completely removed, they can easily cause yarn wear, tension fluctuations, and even yarn breakage during subsequent yarn winding, seriously affecting production efficiency and product quality. The current method for handling parting lines is mainly manual. The specific process is as follows: after the injection-molded warp tubes have cooled naturally, workers visually identify the position of the parting line and then manually cut off the excess parting line with a tool.

[0003] This traditional model has the following drawbacks: First, it requires high skill from workers, who need to accurately judge the position of the mold parting line and the cutting depth. Novice operators are prone to over-cutting, which can lead to the scrapping of the warp tube or leave mold parting lines that affect its use. Secondly, the rate of missed detection is high. Manual visual inspection is easily affected by factors such as fatigue and light, and it cannot guarantee that the parting lines of all warp tubes will be identified and processed. Third, it is inefficient, as a single person can only process one warp tube at a time, which is difficult to match the needs of mass production, and the labor cost remains high.

[0004] Therefore, there is an urgent need for a high degree of automation, stable processing effect, and batch operation capability for grinding mold lines to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an automatic surface polishing device for glass fiber warp tubes, which integrates air cooling, polishing, and post-polishing inspection into one unit. It requires no manual intervention, greatly reduces reliance on worker skills, avoids subjective errors in manual operation, and improves overall work efficiency, thus meeting the needs of mass production.

[0006] The purpose of this utility model is achieved as follows: An automatic surface polishing device for glass fiber warp tubes includes a frame with a conveyor line, a cooling box, a polishing station, and a testing station. The conveyor line is equipped with at least one positioning fixture for positioning the warp tubes, which keeps the warp tubes in a vertical position. The warp tubes produced from the injection molding machine are sequentially conveyed to the cooling box, the polishing station, and the testing station via the positioning fixture. The bottom of the polishing station and the testing station are equipped with a rotating lifting assembly.

[0007] Preferably, the positioning fixture includes a fixed clamping block and a movable clamping block. The fixed clamping block is fixed on the base, and the movable clamping block is connected to a guide shaft. The guide shaft is slidably mounted on a slide block, which is fixed on the base. A compression spring is sleeved on the guide shaft between the slide block and the movable clamping block.

[0008] Preferably, the rotary lifting assembly includes a rotary cylinder, an electric push rod, and a spindle profiler. The rotary cylinder is fixed on the frame, the rotating end of the rotary cylinder is connected to the electric push rod, the telescopic rod of the electric push rod is connected to the spindle profiler, the spindle profiler passes through the base to lift the warp tube, and the base has a through hole corresponding to the spindle profiler.

[0009] Preferably, the polishing station includes a polishing cover, a first positioning sensor, and a floating polishing head. The polishing cover is fixed on the frame, the first positioning sensor is fixed on the polishing cover, and the first positioning sensor is used to sense the position of the warp tube. The floating polishing head is fixed on a first transverse cylinder, and the first transverse cylinder is fixed on the vertical slider of the first linear module.

[0010] Preferably, the polishing station is further equipped with a dust collection hood, an air gun, and a pressing cylinder.

The pressing cylinder is used to return the warp tubes to their original position.

[0011] Preferably, the detection station includes a detection box, a second positioning sensor, a first industrial camera, a second industrial camera, and a gripper cylinder.

[0012] The beneficial effects of this utility model are: It achieves full automation from feeding, cooling, grinding to inspection and sorting, without the need for human intervention, greatly reducing reliance on worker skills, avoiding subjective errors in manual operation, and improving overall operational efficiency, which can meet the needs of mass production. Mechanical positioning and constant force grinding eliminate human interference, ensuring the consistency of the removal effect of the die-cutting line for each warp tube, and significantly improving the product yield. Using industrial cameras for 100% online inspection avoids the fatigue and negligence of manual visual inspection, fundamentally solving the problem of missed inspections and ensuring the quality of products leaving the factory. The entire process requires no manual intervention in grinding and testing, completely eliminating safety hazards posed by cutting tools and meeting the requirements of modern industrial safety production.

Detailed Implementation

[0019] See Figure 1-5 This utility model relates to an automatic surface polishing device for glass fiber warp tubes, including a frame 1. The frame 1 is equipped with a conveyor line 2, a cooling box 3, a polishing station 4, and a testing station 5. The conveyor line 2 is equipped with at least one positioning fixture 7 for positioning the warp tube 6. The positioning fixture 7 keeps the warp tube 6 in a vertical state. The warp tube 6 produced from the injection molding machine is sequentially conveyed to the cooling box 3, the polishing station 4, and the testing station 5 via the positioning fixture 7. The top surface and both sides of the cooling box 3 are equipped with axial flow fans to uniformly and rapidly force-cool the high-temperature warp tube 6, causing its temperature to drop rapidly and providing a stable workpiece state for subsequent polishing operations.

[0020] The positioning fixture 7 includes a fixed clamping block 7.1 and a movable clamping block 7.2. The fixed clamping block 7.1 is fixed on the base 7.3, and the movable clamping block 7.2 is connected to a guide shaft 7.4. The guide shaft 7.4 is slidably mounted on a slide block 7.5, which is fixed on the base 7.3. A compression spring 7.6 is sleeved on the guide shaft 7.4 between the slide block 7.5 and the movable clamping block 7.2. When the warp tube 6 is placed on the positioning fixture 7, the bottom of the warp tube 6 pushes the movable clamping block 7.2 away from the fixed clamping block 7.1, compressing the compression spring and fixing the position of the warp tube 6.

[0021] Both the grinding station 4 and the inspection station 5 are equipped with a rotary lifting assembly 8 at their bottom. The rotary lifting assembly 8 includes a rotary cylinder 8.1, an electric push rod 8.2, and a spindle profiler 8.3. The rotary cylinder 8.1 is fixed on the frame 1. The rotating end of the rotary cylinder 8.1 is connected to the electric push rod 8.2. The telescopic rod of the electric push rod 8.2 is connected to the spindle profiler 8.3. The spindle profiler 8.3 passes through the base 7.3 to lift the warp tube 6. The base 7.3 has a through hole corresponding to the spindle profiler 8.3.

[0022] The polishing station 4 includes a polishing cover 4.1, a first positioning sensor 4.2, and a floating polishing head 4.3. The polishing cover 4.1 is fixed on the frame 1, and the first positioning sensor 4.2 is fixed on the polishing cover 4.1. The first positioning sensor 4.2 is used to sense when the warp tube reaches the designated polishing position. Then, the electric push rod 8.2 is raised, causing the spindle profile 8.3 to insert into the inner hole of the warp tube and push it away from the positioning fixture. The rotary cylinder 8.1 then drives the warp tube to rotate at a uniform speed. The floating polishing head 4.3 is fixed on the first horizontal cylinder 4.4, which is fixed on the vertical slider of the first linear module 4.5. The floating polishing head 4.3 is driven by a servo motor. The control system presets the size parameters of different types of warp tubes and controls the floating polishing head 4.3 to accurately remove the parting line and gate on the outer wall of the rotating warp tube.

[0023] The polishing station 4 is also equipped with a dust collection hood 4.6, an air gun, and a pressing cylinder 4.7. The dust collection hood 4.6 is connected to an external vacuum cleaner via a pipe to collect dust generated during the polishing process. The air gun is used to blow air through the polished warp tubes to prepare for subsequent inspection and improve the accuracy of the inspection. The pressing cylinder 4.7 is used to return the warp tubes to their original position. The pressing cylinder 4.7 presses down on the end of the warp tube, driving the warp tube back between the two clamping blocks of the positioning fixture.

[0024] The inspection station 5 includes an inspection housing 5.1, a second positioning sensor 5.2, a first industrial camera 5.3, a second industrial camera 5.4, and a gripper cylinder 5.5. The first industrial camera 5.3 and the second industrial camera 5.4 are respectively mounted on the side and top surfaces of the inspection housing 5.1. The gripper cylinder 5.5 is used to return the warp tube to its original position after inspection. The gripper cylinder 5.5 is connected to a second transverse cylinder 5.6, which is connected to the vertical slider of the second linear module 5.7. The second positioning sensor 5.2 is used to sense the position of the warp tube. The first industrial camera 5.3 is used to photograph the outer contour of the warp tube, and its surface contour dimensions and the smoothness of the polished area are analyzed through image processing. The second industrial camera 5.4 is used to photograph vertically downwards, and its circular runout accuracy is detected by analyzing the image runout of the warp tube end face.

[0025] The warp tubes coming out of the inspection station are removed from the conveyor line by a material unloading robot (not shown in the figure). The material unloading robot stores qualified and unqualified products separately according to the inspection results.

[0026] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
