Description

Technical Field

[0001] This utility model relates to the field of pressure plate warping monitoring technology, specifically a warping deformation detection device for pressure plate processing. Background Technology

[0002] Warpage occurs when a plastic part deviates from its designed shape and undergoes surface distortion. Warpage is caused by uneven shrinkage of the molded part. If the entire plastic part has a uniform shrinkage rate, the deformation will not result in warpage, but only in a reduction in size. However, due to the interaction of many factors such as molecular chain / fiber alignment, mold cooling, part design, mold design, and molding conditions, achieving low or uniform shrinkage is a very complex task.

[0003] The existing reference is Chinese utility model patent with announcement number CN220288458U, which discloses that this utility model belongs to the technical field and specifically relates to an online warping monitoring device for sheet metal, including a bow plate and two sensors. The two sensors are arranged on both sides of the bow plate, and a guide structure is provided below the bow plate. This utility model, through the design of the guide structure, allows the sheet metal to be tested to pass through the test area more easily under the action of external force, thus completing the test. The device has a simple structure, is easy to operate, and is conducive to promotion.

[0004] The aforementioned warpage monitoring device supports the board material through guide wheels at the bottom, facilitating its movement. When warpage occurs at either end of the board material perpendicular to the direction of movement, the center of the board material is supported by the guide wheels, and the force applied to the force-sensitive sensor on both sides is the same, affecting the detection results. At the same time, the weight between different areas of the board material during the detection process will affect the degree of warpage. When the concave part of the board material contacts the guide wheels, the warpage rate at both ends of the board material will change, affecting the detection. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a warping deformation detection device for pressure plate processing, which solves the problems that the weight of the plate itself affects the warping rate and that the detection results are prone to errors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A warping deformation detection device for wire pressing plate processing includes a support frame, and a detection mechanism is disposed above the support frame.

[0007] A conveying unit, which is disposed between support frames for conveying pressure plates;

[0008] The detection unit includes a rodless cylinder fixedly installed between support frames. A fixed frame is installed above the slider of the rodless cylinder and the support frame. A downward piston is fixedly installed below the fixed frame. A connecting pipe is fixedly installed at the bottom end of the downward piston on one side of the slider of the rodless cylinder. A pressure bearing is fixedly installed at the bottom end of the connecting pipe. A stepper motor is fixedly installed inside the connecting pipe. A pressure sensor is fixedly installed at the bottom end of the stepper motor shaft and the bottom end of the downward piston above the support frame. A limiting component for limiting the position of the pressure plate is installed below the pressure sensor.

[0009] Preferably, the conveying unit includes synchronous rollers that are inserted and installed at both ends of the support frame, and a synchronous belt is fitted and installed on the outer side of the synchronous rollers. The conveying unit also includes a support shaft that is equidistantly installed at the center of the support frame, and a drive motor is inserted and installed on one side of the left synchronous roller.

[0010] Preferably, the synchronous roller, the support shaft, and the support frame are all rotatably connected, the top of the synchronous roller is flush with the top of the support shaft, and the top of the side of the support shaft is in contact with the top of the inner side of the synchronous belt.

[0011] Preferably, the left and right ends of the rodless cylinder are fixedly connected to the two side support frames respectively, and there are a total of five downward pistons, with four of the downward pistons installed at both ends of the "T"-shaped structure at the top of the left and right side support frames respectively.

[0012] Preferably, the connecting pipe is cylindrical, with its top end fixedly connected to the bottom end of the piston on one side of the rodless cylinder slider, and the bottom end of the connecting pipe is rotatably connected to the pressure sensor through a pressure bearing.

[0013] Preferably, the limiting component includes a connecting frame fixedly installed at the bottom of the pressure sensor, a connecting bearing is fitted inside the connecting frame, and a guide wheel is inserted inside the connecting bearing.

[0014] Beneficial effects

[0015] This invention provides a warping deformation detection device for wire pressing plate processing. Compared with the prior art, it has the following advantages:

[0016] (1) The warping deformation detection device for the pressure plate processing, through the setting of the pressure sensor, the bottom end of the rodless cylinder is connected to the pressure sensor through the connecting pipe and the pressure bearing. The stepper motor inside the rodless cylinder can adjust the orientation of the bottom guide wheel shaft. The position of the bottom guide wheel is adjusted by the downward piston so that the guide wheel contacts the pressure plate and the pressure sensor is kept consistent. If the pressure plate warps, the detection value of the pressure sensor will change when passing the bottom guide wheel of the pressure sensor. The detection accuracy is improved by the pressure sensor installed in a five-point layout. At the same time, after the axial direction of the lower guide wheel is adjusted by the stepper motor, the drive motor stops. The warping of the plate in the front and rear directions can be detected by the downward piston driven by the rodless cylinder, thereby improving the detection accuracy.

[0017] (2) The warping deformation detection device for the pressure plate processing, through the setting of the pressure piston, can adjust the position of the guide wheel. During the detection process, the guide wheel always presses the pressure plate on the upper surface of the synchronous belt above the support shaft. The synchronous roller is driven by the drive motor to rotate, so that the synchronous belt outside the synchronous roller rotates to transport the pressure plate. The position between the synchronous belt and the pressure plate contact surface is restricted by the support shaft below the synchronous belt to prevent the synchronous belt from deforming under pressure. Due to the five-point installation method of the guide wheel, a downward force can be applied to the pressure plate at the center and four corners. When the pressure plate warps, the detection data of the five pressure sensors cannot be consistent. This method can make the pressure plate tend to be flat during the detection process. The reaction force applied by the warped part of the pressure plate to the guide wheel when the pressure plate is pressed reflects whether the pressure plate warps. This avoids the situation where the weight of the pressure plate affects the warping rate and affects the detection accuracy. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a warping deformation detection device for wire pressing plate processing, including a support frame 1, and a detection mechanism 2 is arranged above the support frame 1.

[0025] The conveying unit 21 is disposed between the support frames 1 for conveying the pressure plate. The conveying unit 21 includes synchronous rollers 211 inserted and installed at both ends of the support frame 1. A synchronous belt 212 is fitted and installed on the outer side of the synchronous rollers 211. The conveying unit 21 also includes a support shaft 213 installed at equal distances on the left and right sides at the center of the support frame 1. A drive motor 214 is inserted and installed on one side of the left synchronous roller 211. The synchronous rollers 211, the support shaft 213 and the support frame 1 are all rotatably connected. The top of the synchronous rollers 211 is flush with the top of the support shaft 213. The top side of the support shaft 213 contacts the top inner side of the synchronous belt 212.

[0026] Specifically, the support frame 1 can limit the position of the synchronous roller 211. The synchronous roller 211 is driven to rotate by the drive motor 214, which causes the synchronous belt 212 on the outside of the synchronous roller 211 to rotate, so as to transport the pressure plate. The support shaft 213 is located below the synchronous belt 212 to limit the position between the synchronous belt 212 and the contact surface of the pressure plate, so as to prevent the synchronous belt 212 from being deformed by pressure.

[0027] The detection unit 22 includes a rodless cylinder 221 fixedly installed between the support frames 1. A fixed frame 222 is installed above the slider of the rodless cylinder 221 and the support frame 1. A pressing piston 223 is fixedly installed below the fixed frame 222. A connecting pipe 224 is fixedly installed at the bottom end of the pressing piston 223 on one side of the slider of the rodless cylinder 221. A pressure bearing 225 is fixedly installed at the bottom end of the connecting pipe 224. A stepper motor 226 is fixedly installed inside the connecting pipe 224. A pressure sensor 227 is fixedly installed at the bottom end of the shaft of the stepper motor 226 and at the bottom end of the pressing piston 223 above the support frame 1. A limiter for limiting the position of the pressure plate is installed below the pressure sensor 227. The left and right ends of the rodless cylinder 221 are fixedly connected to the two side support frames 1 respectively. There are five downward pistons 223. Four downward pistons 223 are installed at the two ends of the "T"-shaped structure at the top of the left and right side support frames 1 respectively. The connecting pipe 224 is cylindrical. Its top end is fixedly connected to the bottom end of the downward piston 223 on the slider side of the rodless cylinder 221. The bottom end of the connecting pipe 224 is rotatably connected to the pressure sensor 227 through the pressure bearing 225. The limiting component 228 includes a connecting frame 2281 fixedly installed at the bottom of the pressure sensor 227. A connecting bearing 2282 is fitted inside the connecting frame 2281. A guide wheel 2283 is inserted inside the connecting bearing 2282.

[0028] Specifically, the pressing piston 223 is mounted on both ends of the "T"-shaped structure at the top of the support frame 1 and on one side of the slider of the rodless cylinder 221 via the fixing bracket 222, thereby limiting the position of the bottom guide wheel 2283 of the pressing piston 223. The bottom end of the rodless cylinder 221 is rotatably connected to the pressure sensor 227 via the connecting pipe 224, the pressure bearing 225, and the stepper motor 226 inside the rodless cylinder 221 can adjust the orientation of the bottom guide wheel 2283 axle. When the conveying unit 21 moves the pressure plate, the orientation of the bottom guide wheel 2283 axle of the rodless cylinder 221 is consistent with the orientation of the guide wheel 2283 axle below the support frame 1, which is adjusted by the pressing piston 223. The position of the bottom guide wheel 2283 ensures that it contacts the pressure plate and maintains consistent pressure on the pressure sensor 227. If the pressure plate warps, the pressure sensor 227 will change its reading when passing through the bottom guide wheel 2283. The pressure sensor 227 is installed in a five-point layout to improve detection accuracy. After adjusting the axial direction of the lower guide wheel 2283 by the stepper motor 226, the rodless cylinder 221 can drive the lower piston 223 to move and detect warping in the front-to-back direction of the plate. All contents not described in detail in this specification are prior art known to those skilled in the art.

[0029] During operation, the bottom end of the rodless cylinder 221 is rotatably connected to the pressure sensor 227 via the connecting pipe 224, pressure bearing 225, and connecting pipe 224. The stepper motor 226 inside the rodless cylinder 221 adjusts the orientation of the bottom guide wheel 2283's axle. The position of the bottom guide wheel 2283 is adjusted by the pressing piston 223, ensuring contact between the guide wheel 2283 and the pressure plate, and maintaining consistent pressure on the pressure sensor 227. If the pressure plate warps, the pressure sensor 227's reading will change as it passes the bottom guide wheel 2283. The five-point arrangement of the pressure sensor 227 improves detection accuracy. Simultaneously, after adjusting the axial direction of the lower guide wheel 2283 via the stepper motor 226, the drive motor 214 stops. The rodless cylinder 221 then moves the pressing piston 223 to detect warping in the front-to-back direction of the plate, further improving detection accuracy. 3. The position of the guide wheel 2283 can be adjusted so that during the detection process, the guide wheel 2283 always presses the pressure plate against the upper surface of the synchronous belt 212 above the support shaft 213. The synchronous roller 211 is driven to rotate by the drive motor 214, which in turn causes the synchronous belt 212 outside the synchronous roller 211 to rotate, thereby transporting the pressure plate. The position between the synchronous belt 212 and the pressure plate contact surface is restricted by the support shaft 213 below the synchronous belt 212 to prevent the synchronous belt 212 from deforming under pressure. Due to the five-point installation method of the guide wheel 2283, a downward force can be applied to the pressure plate at the center and four corners. When the pressure plate warps, the detection data of the five pressure sensors 227 cannot be consistent. This method can make the pressure plate tend to be flat during the detection process. The reaction force exerted by the warped part of the pressure plate on the guide wheel 2283 when the pressure plate is pressed reflects whether the pressure plate has warped, avoiding the situation where the weight of the pressure plate affects the warping rate and thus affects the detection accuracy.
