Description

Technical Field

[0001] This invention relates to the technical field of glass fiber polyurethane sheet conveying and testing, specifically to an automatic centering conveying and testing device and method for glass fiber polyurethane sheets. Background Technology

[0002] Fiberglass polyurethane panels (also known as fiberglass reinforced polyurethane composites) are high-performance composite materials made of glass fiber as reinforcement and polyurethane resin as matrix, typically formed through processes such as pultrusion. They possess excellent properties such as lightweight, high strength, energy efficiency, thermal insulation, fire resistance, and weather resistance. Initially widely used in the automotive, wind power, and aerospace industries, they are now becoming an ideal material for energy-efficient building doors, windows, and curtain walls.

[0003] After production and molding, fiberglass polyurethane sheets need to undergo conveying and quality inspection. Because the sheets are lightweight, high-strength, and easy to protect, roller conveyor lines are usually used to complete the transfer operation. While the sheets are being transported smoothly, visual inspection, dimensional measurement, and density uniformity testing equipment can be used to accurately screen the surface defects, specifications, and physical properties of the sheets during the conveying process. This avoids surface damage caused by friction and improves the efficiency of integrated inspection and conveying, ensuring the quality stability of the sheets leaving the factory.

[0004] In the continuous production of fiberglass polyurethane sheets, maintaining precise alignment and stable posture of the sheets during the conveying process is a key prerequisite for ensuring the quality of subsequent testing, processing and other processes; especially when facing the trend of multi-specification and small-batch production, higher requirements are placed on the flexibility and intelligence of the conveyor line.

[0005] However, in actual production scenarios, the feed width of traditional roller conveyor lines often relies on manual operation or pre-setting, making it difficult to quickly and accurately adapt to different widths of sheet metal without stopping the machine. On the other hand, the deviation and skew caused by uneven friction or slight changes in force during long-distance conveying of sheet metal lack real-time correction methods. If the deviation or skewed sheet metal is not corrected in time and directly enters the subsequent inspection stage, it will cause the shooting area of ​​the inspection camera to deviate from the preset reference position, resulting in distortion of inspection data such as dimensional measurement and surface defect identification, and reducing the accuracy and reliability of the inspection results. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic centering, conveying, and testing device and method for glass fiber polyurethane sheets, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic centering conveying and inspection device for fiberglass polyurethane sheets includes a roller conveyor line and a support frame connected to the top of the roller conveyor line. A support base and a motor are connected to the bottom of the support base at the bottom of the roller conveyor line. A deflection shaft and a deflection plate fixedly sleeved on the deflection shaft are connected to the output shaft of the motor. The deflection plate is slidably engaged with a limiting mechanism connected to the top of the support base. A dragging mechanism is rotatably connected to the deflection plate. Two centering push plates are connected to the dragging mechanism. The centering push plates are provided with multiple sets of rollers and a sliding cavity opened in the middle section of the centering push plates. A sliding component is connected to the bottom of the support frame, and a correction mechanism for aligning the sheets is connected to the top of the support frame. A visual inspection device for inspecting the sheets is provided at the rear end of the roller conveyor line.

[0009] An automatic centering, conveying, and testing device for fiberglass polyurethane sheets, as described above, includes a limiting mechanism comprising a limiting base connected to the support seat and two arc-shaped grooves formed on the limiting base. The bottom of the deflection plate is connected to two fixing rods, which are slidably mounted on the two arc-shaped grooves.

[0010] An automatic centering, conveying, and testing device for fiberglass polyurethane sheets, as described above, includes a dragging mechanism comprising a first slide rail connected to both ends of the support base and a sliding plate slidably mounted on the first slide rail, with a connecting arm rotatably connected to one end of each of the two sliding plates.

[0011] An automatic centering conveying and testing device for fiberglass polyurethane sheets, as described above, comprises two connecting arms rotatably connected to both ends of a deflection plate, and two centering push plates connected to the tops of two sliding plates.

[0012] An automatic centering, conveying, and testing device for fiberglass polyurethane sheets, as described above, includes a sliding assembly comprising a limiting frame connected to the support base and sliding blocks slidably mounted at both ends of the limiting frame, with an abutment plate connected to the bottom of the sliding blocks.

[0013] An automatic centering conveying and testing device for fiberglass polyurethane sheets, as described above, comprises two abutment plates that are slidably installed on the sliding cavities in the middle sections of two centering push plates. Springs are fixedly installed inside the two sliding cavities, and the two springs abut against one end of the two abutment plates respectively.

[0014] An automatic centering conveying and testing device for fiberglass polyurethane sheets, as described above, has slots on both abutment plates and two centering push plates, and one end of each abutment plate is connected to a first beveled edge.

[0015] An automatic centering and conveying inspection device for fiberglass polyurethane sheets as described above: the correction mechanism includes a camera connected to the top of the support base and a cylinder that communicates remotely with the camera for control. The bottom of the cylinder is connected to a support member, and two second slide rails are slidably installed at both ends of the support member. The two second slide rails are respectively connected to both ends of the support base.

[0016] An automatic centering conveying and testing device for fiberglass polyurethane sheets as described above: both ends of the support member are slidably mounted with lifting plates and second inclined edge members connected to one side of the lifting plates. The two second inclined edge members are respectively squeezed into the two first inclined edge members. The bottom of the lifting plate is connected with an insertion rod, which is inserted into the slots on the abutment plate and the centering push plate.

[0017] The inspection method using an automated centering and conveying inspection device for fiberglass polyurethane sheets as described above includes the following steps:

[0018] Step 1: During operation, the motor is started to drive the deflection shaft and deflection plate to deflect slightly. During the process, the deflection plate will pull the sliding plate through the connecting arms on both sides, and simultaneously drive the centering push plate to move in the center or expand outward.

[0019] Step 2: During the conveying process, the camera captures and identifies the conveying posture of the board in real time. When a slight tilt of the board is detected, an execution signal is sent to the cylinder, at which point the support component moves the two lifting plates.

[0020] Step 3: At the same time, the insertion rod separates from the slots on the abutment plate and the centering push plate, the lifting plate continues to rise, and the second inclined piece on one side squeezes the first inclined piece;

[0021] Step 4: The two contact plates move inward to correct the posture of the board on both sides. Finally, the board is transported to the visual inspection equipment for inspection.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By symmetrically setting centering push plates on both sides of the conveyor frame and linking them with the same transmission mechanism, the synchronous and precise adjustment of the centering amplitude is achieved. This allows for rapid adaptation to plates of different widths, ensuring that they are always in the centered reference position on the conveying path. At the same time, the system integrates a real-time correction unit based on vision detection. When the camera detects a slight tilt of the plate during its movement, it can immediately drive the abutment plates on both sides to perform fine-tuning actions, dynamically straightening the plate's posture. This design enables the plate to automatically reach and maintain a centered and straight state before entering the inspection station.

[0024] This invention effectively solves the problems of poor adaptability of traditional conveyor lines and easy deviation and skewing of plates, which leads to a decrease in detection accuracy, and improves the continuity and reliability of the conveying and detection process.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Please see Figures 1-14 As an embodiment of the present invention, the automatic centering conveying and testing equipment for fiberglass polyurethane sheets includes a roller conveyor line 1 and a support frame 2 connected to the top of the roller conveyor line 1. The bottom of the roller conveyor line 1 is connected to a support base 3 and a motor 4 connected to the bottom of the support base 3. The output shaft of the motor 4 is connected to a deflection shaft 5 and a deflection plate 6 fixedly sleeved on the deflection shaft 5. The deflection plate 6 is slidably engaged with a limiting mechanism connected to the top of the support base 3. A dragging mechanism is rotatably connected to the deflection plate 6. Two centering push plates 11 are connected to the dragging mechanism. The centering push plates 11 are provided with multiple sets of rollers 12 and a sliding cavity 13 opened in the middle section of the centering push plates 11. The bottom of the support frame 2 is connected to a sliding component. The top of the support frame 2 is connected to a correction mechanism for aligning the sheet. A visual inspection device 26 for inspecting the sheet is provided at the rear end of the roller conveyor line 1.

[0042] In this embodiment, two sets of centering push plates 11 are symmetrically arranged on both sides of the conveyor frame. A linkage dragging mechanism is configured between the two sets of centering push plates. The dragging mechanism enables the synchronous and same-width spacing adjustment of the two sets of centering push plates 11, thereby flexibly adapting to fiberglass polyurethane sheets of different widths. During the conveying process, the conveying posture of the sheet is collected and identified in real time through the built-in system of the correction mechanism. When a slight tilt of the sheet is detected, the correction mechanism can act synchronously on both sides of the sheet to accurately correct its posture. Ultimately, it ensures that the sheet remains centered and aligned with the conveyor frame throughout the entire conveying process and enters the subsequent inspection station in a straight posture.

[0043] Both centering push plates 11 are rotatably equipped with rollers 12 for rolling cooperation with the edge of the plate, which can guide and adjust the position when in contact with the plate.

[0044] As a further embodiment of the present invention, the limiting mechanism includes a limiting base 7 connected to the support base 3 and two arc-shaped grooves formed on the limiting base 7. The bottom of the deflection plate 6 is connected to two fixing rods, which are slidably mounted on the two arc-shaped grooves respectively.

[0045] In this embodiment, two arc-shaped grooves are provided on the limiting chassis 7, and two fixing rods are fixed to the bottom of the deflection plate 6 at the top. The two fixing rods are slidably installed on the two arc-shaped grooves to limit the deflection angle of the deflection plate 6.

[0046] As a further embodiment of the present invention, the dragging mechanism includes a first slide rail 9 connected to both ends of the support base 3 and a sliding plate 10 slidably mounted on the first slide rail 9, with a connecting arm 8 rotatably connected to one end of each of the two sliding plates 10.

[0047] In this embodiment, a sliding plate 10 is slidably mounted on the first slide rail 9 so that it can slide smoothly.

[0048] As a further embodiment of the present invention, the two connecting arms 8 are rotatably connected to the two ends of the deflection plate 6, and the two centering push plates 11 are respectively connected to the top of the two sliding plates 10.

[0049] In this embodiment, connecting arms 8 are rotatably mounted on both ends of the deflection plate 6. The rotation of the deflection plate 6 drives the connecting arms 8 to move, and the connecting arms 8 pull the sliding plate 10, which can drive the two sliding plates 10 to move synchronously.

[0050] As a further embodiment of the present invention, the sliding component includes a limiting frame 14 connected to the support base 3 and sliding blocks slidably installed at both ends of the limiting frame 14, with the bottom of the sliding blocks connected to an abutment plate 15.

[0051] In this embodiment, two sliding blocks are slidably mounted on the limiting frame 14, and the bottom of the sliding blocks is connected to the abutment plate 15.

[0052] As a further embodiment of the present invention, two abutment plates 15 are slidably mounted on the sliding cavities 13 in the middle section of the two centering push plates 11, and springs 16 are fixedly installed inside the two sliding cavities 13, with the two springs 16 abutting against one end of the two abutment plates 15 respectively.

[0053] In this embodiment, a connecting rod is provided at one end of the abutment plate 15. The connecting rod of the abutment plate 15 is slidably mounted on the sliding cavity 13 in the middle section of the centering push plate 11. At the same time, the spring 16 abuts against the connecting rod. When the abutment plate 15 slides outward, it will compress the spring 16.

[0054] As a further embodiment of the present invention, slots 18 are provided on both abutment plates 15 and two centering push plates 11, and one end of the abutment plate 15 is connected to a first inclined edge member 17.

[0055] In this embodiment, slots 18 are provided on both the centering push plate 11 and the abutment plate 15. The slots on the abutment plate 15 completely penetrate the slots, and the top of the abutment plate 15 is connected to the first beveled edge 17.

[0056] As a further embodiment of the present invention, the correction mechanism includes a camera 20 connected to the top of the support base 3 and a cylinder 19 remotely communicating with the camera 20 for control. The bottom of the cylinder 19 is connected to a support member 21. Both ends of the support member 21 are slidably mounted with second slide rails 22, and the two second slide rails 22 are respectively connected to both ends of the support base 3.

[0057] In this embodiment, the camera 20 can scan the position of the conveyed plate based on visual detection. When the camera 20 detects that the plate is slightly tilted during the process, it sends an execution signal to the cylinder 19. The cylinder 19 can drive the support member 21 to move up and down. The second slide rail 22 supports the movement of the support member 21. The support member 21 is an elliptical tube.

[0058] As a further embodiment of the present invention, both ends of the support member 21 are slidably mounted with lifting plates 23 and second inclined edge members 24 connected to one side of the lifting plate 23. The two second inclined edge members 24 are respectively squeezed into the two first inclined edge members 17. The bottom of the lifting plate 23 is connected with a plug rod 25, and the plug rod 25 is inserted into the slot 18 on the abutment plate 15 and the centering push plate 11.

[0059] In this embodiment, during operation, the starting motor 4 drives the deflection shaft 5 and the deflection plate 6 to deflect slightly. During this process, the deflection plate 6 pulls the sliding plate 10 through the connecting arms 8 on both sides, and simultaneously drives the centering push plate 11 to move in center or expand outward to adjust the spacing. During the conveying of the plate, the camera 20 collects and identifies the conveying posture of the plate in real time. When a slight tilt of the plate is detected, an execution signal is sent to the cylinder 19. At this time, the support member 21 drives the two lifting plates 23 to move, and the insertion rod 25 separates from the slot 18 on the abutment plate 15 and the centering push plate 11, so that the fixing of the abutment plate 15 and the centering push plate 11 is canceled. Then the lifting plate 23 continues to rise, and the second inclined edge member 24 on one side squeezes the first inclined edge member 17, thereby driving the two abutment plates 15 to move inward, thereby accurately correcting the posture of the two sides of the moving plate, and finally ensuring that the plate remains centered and aligned with the conveyor frame throughout the entire conveying process.

[0060] The inspection method using an automated centering and conveying inspection device for fiberglass polyurethane sheets as described above includes the following steps:

[0061] Step 1: During operation, the motor 4 drives the deflection shaft 5 and the deflection plate 6 to deflect slightly. During the process, the deflection plate 6 will pull the sliding plate 10 through the connecting arms 8 on both sides, and simultaneously drive the centering push plate 11 to move in the center or expand outward.

[0062] Step 2: During the conveying process, the camera 20 collects and identifies the conveying posture of the board in real time. When a slight tilt of the board is detected, an execution signal is sent to the cylinder 19. At this time, the support 21 drives the two lifting plates 23 to move.

[0063] Step 3: At the same time, the insertion rod 25 separates from the slot 18 on the abutment plate 15 and the centering push plate 11, the lifting plate 23 continues to rise, and the second inclined piece 24 on one side squeezes the first inclined piece 17.

[0064] Step 4: The two abutment plates 15 move inward to correct the posture of both sides of the board. Finally, the board is transported to the visual inspection equipment 26 for inspection.

[0065] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
