Description

Technical Field

[0001] This invention relates to the field of board material testing equipment, specifically a testing device for preventing deformation during the processing of wooden door panels. Background Technology

[0002] After the production and processing of wooden door panels, they are prone to quality defects such as warping and denting due to factors such as the moisture content of raw materials, hot pressing process, and ambient temperature and humidity. Deformation of the panels will directly cause problems such as uneven gaps in subsequent door assembly and poor closure. Therefore, deformation detection of the panels before leaving the factory is a key quality control process in the production of wooden doors.

[0003] Currently, most of the industry's methods for detecting deformation of wooden door panels rely on manual methods combined with simple measuring tools. Operators manually measure multiple points on the panels using rulers and feeler gauges, and visually observe the defects of the panels. This method is not only inefficient, but also has large errors in manual readings. The quality of the tests is significantly affected by the operator's experience, resulting in poor consistency and the potential for blind spots. Furthermore, since wooden doors are double-sided, they need to be manually flipped, which is laborious and time-consuming. Summary of the Invention

[0015] Preferably, the tray in the bearing unit can be switched to be used individually to fit plates of different thicknesses and surfaces.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The flipping assembly adopts a rack and pinion transmission system, converting linear power into rotational power to flip the board. Relying on the mechanical characteristics of the rack and pinion, the transmission is self-locking, which can resist the overturning torque caused by the large weight of the wooden door board itself. It effectively avoids the board from tilting or shifting position after flipping, keeping the clamping posture stable. From a mechanical point of view, it ensures that the detection benchmark remains unchanged, reduces the error in detection data caused by the tilt of the board, and eliminates the need for additional complex locking components. The structure is simple and reliable. At the same time, the clamping structure has symmetrically arranged load-bearing units. The board is supported and clamped at the four corners through the switchable working mode of the upper and lower sides of the clamping plate. The board is evenly stressed and is not easy to loosen or shake during rotation, making the flipping operation safe and stable.

[0018] 2. The flipping structure allows for adjustment of the relative distance between the two sets of flipping components via the first electric slide rail, adapting to test plates of different widths; the clamping structure relies on the second electric slide rail to adjust the base spacing of the mounting base, and can also flexibly adjust the effective span of the clamping mechanism by increasing or decreasing the number of adapter arms and adapter rods, and locking them with mounting bolts and adapter bolts, adapting to wooden door panels and doors of different lengths; each component supports detachable assembly, allowing compatibility with various workpiece specifications without replacing the entire fixture, reducing fixture modification costs and improving the device's versatility.

[0019] 3. The workpiece reversal is achieved by using a flipping structure to drive the clamping structure, enabling double-sided, full-dimensional inspection without disassembling the sheet metal: the camera can determine double-sided appearance defects, and multiple laser rangefinders arranged in the housing can collect double-sided flatness data, effectively identifying deformation defects such as bending, warping, and unevenness of the sheet metal; a single clamping can complete the inspection of both sides, eliminating the need for manual disassembly, flipping, and re-clamping, avoiding positioning deviations caused by secondary clamping, and preventing missed inspections due to clamping components obstructing the inspection surface; in addition, the inspection execution components support quick replacement. After removing the laser rangefinder assembly and replacing it with the pressure arm, a compressive strength test can be carried out on the same clamping and positioning basis, testing the critical load of the sheet metal under compressive deformation, combining deformation detection and compressive strength testing functions, reducing equipment investment and minimizing time loss from multiple clamping operations.

[0020] In summary, this invention can complete multiple processes such as clamping, flipping, double-sided appearance inspection, double-sided flatness inspection, or pressure resistance testing of a workpiece in a single clamping, significantly reducing the workload of manual handling, flipping, and equipment changing; it uses cameras and laser rangefinders to achieve objective quantitative data collection, replacing manual visual observation and manual measurement, avoiding errors caused by human readings and subjective judgments, and making the test results more objective and accurate.

[0031] The following will refer to the appendices in the embodiments of the present invention. Figures 1-9 For further details:

[0032] This invention provides a technical solution: a testing device for preventing deformation in the processing of wooden door panels, comprising a base 1, a flipping structure 2 fixedly disposed at the middle of the left end of the base 1, a pair of clamping structures 3 symmetrically disposed on the flipping structure 2, and a detection structure 4 disposed on the upper wall of the right end of the base 1; the flipping structure 2 is used to adjust the relative spacing and drive the clamping structures 3 to flip, facilitating double-sided detection, the clamping structures 3 are used to fix the panels and can accommodate reversal and unobstructed detection, and the detection structure 4 is used to detect flatness and appearance, and can perform pressure resistance testing.

[0033] As a preferred embodiment, the flipping structure 2 includes a base 21, a first electric slide rail 22, and a pair of flipping components 23. The base 21 is fixedly disposed at the middle of the left end of the base 1, and the first electric slide rail 22 is disposed on the right side of the base 21. The slider on the first electric slide rail 22 is on the same horizontal plane as the base 21. The pair of flipping components 23 are respectively disposed on the first slider of the base 21 and the first electric slide rail 22, and the relative spacing of the flipping components 23 can be adjusted. The base 21 serves as the installation reference for one side of the flipping component 23, and the other side of the flipping component 23 is mounted on the slider of the first electric slide rail 22. The first electric slide rail 22 drives the slider to move linearly, causing the two sets of flipping components 23 to move closer or further apart, thereby adjusting the center distance between the two sets of flipping components 23 to adapt to test plates or doors of different widths. The slider and the base 21 are kept on the same horizontal plane to ensure that the two sides of the flipping components 23 are coaxial and at the same height, providing an installation reference for the smooth flipping of the subsequent clamping structure 3.

[0034] More specifically, by flexibly adjusting the relative spacing of the two sets of flipping components 23, the device can be adapted to wooden door panels of different widths, thus improving its versatility. By ensuring that the slider on the first electric slide rail 22 is on the same horizontal plane as the base 21, the installation positions of the two flipping components 23 are at the same height, avoiding misalignment of the panels due to height differences and jamming during flipping. The two sets of flipping components 23 independently support the two ends of the clamping structure 3, dispersing the force and ensuring good overall structural stability during flipping operations.

[0035] As a preferred embodiment, the tilting assembly 23 includes a tilting frame 231, a cylinder base 232, a first hydraulic cylinder body 233, a limiting frame 234, a rack 235, a drive shaft 236, and a gear 237. One end of the tilting frame 231 is fixedly mounted on the base 21, and a bearing is embedded in the middle of the other end of the tilting frame 231. A lifting groove 6 is symmetrically opened on the other end of the tilting frame 231. The cylinder base 232 is fixedly mounted on the side wall of the tilting frame 231 and close to the other end. The first hydraulic cylinder body 233 is fixedly mounted on the cylinder base 232. Both ends of the limiting frame 234 are movably inserted into the lifting groove 6 at the other end of the tilting frame 231, and the limiting frame 234 is located below the bearing. One end of the rack 235 is fixedly mounted on the limiting frame 234, and one end of the rack 235 is connected to the telescopic end of the first hydraulic cylinder body 233. The other end of the rack 235 is provided with teeth and is located in front of the bearing. Shaft 236 is fixedly inserted through the middle of the bearing, and the drive shaft 236 is located on the flipping frame 231 and can rotate. Gear 237 is fixedly installed on one end of the drive shaft 236, and gear 237 meshes with rack 235. The cylinder seat 232 provides mounting support for the body 233 of the first hydraulic cylinder. The body 233 of the first hydraulic cylinder extends and retracts, driving the limit frame 234 to make linear reciprocating motion along the lifting groove 6 of the flipping frame 231. The limit frame 234 synchronously drives the rack 235 to move linearly. The rack 235 meshes with gear 237, converting the linear motion of the hydraulic cylinder into the rotational motion of gear 237 and drive shaft 236. The drive shaft 236 passes through the bearing to achieve rotation, thereby driving the clamping structure 3 installed on the drive shaft 236 to rotate as a whole, completing the flipping of the plate. The lifting groove 6 guides and constrains the limit frame 234, ensuring that the rack 235 and gear 237 are always reliably meshed.

[0036] More specifically, the linear driving force is converted into rotational power through the transmission of the first hydraulic cylinder body 233, rack 235, and gear 237, realizing the automatic flipping of the clamping structure 3 and the board without manual disassembly and flipping. The lifting groove 6 limits and guides the limit frame 234 and rack 235, ensuring the meshing accuracy of the gear 237 and rack 235, avoiding transmission tooth disengagement, and making the flipping action smooth. After the action stops, it can realize mechanical self-locking, which can withstand the large weight of the wooden door board and prevent the board from rotating or tilting due to gravity. It ensures the stability of the board posture after flipping, which is beneficial to subsequent inspection. The bearing supports the rotation of the drive shaft 236, reducing rotational friction resistance and making the flipping process smooth.

[0037] As a preferred embodiment, the clamping structure 3 includes a second electric slide rail 31, a pair of mounting seats 32, mounting bolts 33, several adapter arms 34, several adapter rods 35, several adapter bolts 36, a pair of docking arms 37, and a pair of bearing units 38; the outer shell of the second electric slide rail 31 is fixedly mounted on the other end of the drive shaft 236, and the two ends of the second electric slide rail 31 are symmetrically provided with relatively movable second sliders. The pair of mounting seats 32 are respectively disposed on the second sliders of the second electric slide rail 31 and can move relative to or in opposite directions. Each mounting base 32 has a rectangular mounting opening 7 in the middle. Mounting bolts 33 are screwed onto the middle of the mounting base 32, and the mounting bolts 33 communicate with the mounting opening 7. Several adapter arms 34 have one end that can be connected to each other, and each adapter arm 34 has a pair of adapter holes 8 on its sidewalls at both ends. One end of one adapter arm 34 is inserted into the mounting opening 7 and fixed by the mounting bolts 33. Several adapter rods 35 have both ends inserted into the adapter holes 8 between the adapter arms 34 for connection. Several adapter bolts 36 are screwed onto the adapter... The connecting bolts 36 and connecting rods 35 are tightly fixed to the inner ends of the arm 34. One end of a pair of connecting arms 37 is connected to the connecting arm 34 via the connecting rods 35 and connecting bolts 36, and the other end of each connecting arm 37 is symmetrically screwed with mounting bolts 33. A pair of bearing units 38 are detachably placed on the other end of the connecting arm 37 and fixed by mounting bolts 33. The clamping structure 3 rotates synchronously with the drive shaft 236. The second electric slide rail 31 drives the second sliders on both sides, causing the two mounting seats 32 to move towards or in opposite directions. The clamping base span can be adjusted; the adapter arm 34 is inserted into the mounting port 7 of the mounting base 32 and locked in place by the mounting bolt 33; multiple adapter arms 34 are spliced ​​by inserting adapter rods 35 into the adapter holes 8, and then locked by tightening the adapter rods 35 with adapter bolts 36. The overall extension length can be adjusted by increasing or decreasing the number of adapter arms 34; the docking arm 37 connects the adapter arm 34 and the bearing unit 38. The bearing unit 38 is detachably fixed to the end of the docking arm 37 by the mounting bolts 33, thus completing the assembly of the entire clamping frame to adapt to plates of different lengths and widths.

[0038] More specifically, the second electric slide rail 31 drives the mounting base 32 to slide, enabling electric adjustment of the clamping distance and quick adaptation to the width of the plate. The modular splicing structure of the adapter arm 34 and adapter rod 35 allows for flexible changes in the length of the clamping frame by adding or removing splicing sections, adapting to various length specifications of plates. Multiple bolt-type locking fixation points facilitate easy assembly and disassembly, and the components are detachable for easy maintenance and replacement. The entire clamping structure 3 is mounted on the drive shaft 236 of the flipping structure 2 and can rotate as a whole with the drive shaft 236. The clamping state of the plate will not change during flipping, meeting the clamping requirements for double-sided inspection. The frame-type clamping layout reduces obstruction of the plate inspection surface and lowers the blind spot in the inspection.

[0039] As a preferred embodiment, the bearing unit 38 includes a bearing column 381, a clamping plate 382, ​​a pair of support plates 383, and a pair of electric push rods 384. One end of the bearing column 381 is detachably inserted into the other end of the docking arm 37 and fixed by mounting bolts 33. The clamping plate 382 is fixedly disposed in the middle at the other end of the bearing column 381, and trapezoidal sleeve blocks 9 are symmetrically arranged at both the upper and lower ends of the clamping plate 382. The pair of support plates 383 are both rectangular, and each end of them has a groove that fits into the sleeve block 9. One end of each pair of support plates 383 is movably fitted onto the sleeve block 9 and can slide at the upper limit of the clamping plate 382. The pair of support plates 383 are symmetrically located at the upper and lower ends of the clamping plate 382. One end of each pair of electric push rods 384 is disposed on the clamping plate 382. The sidewalls are symmetrically positioned near the top and bottom ends, with the telescopic ends of a pair of electric push rods 384 connected to the other end of the support plate 383. The bearing column 381 is detachably mounted on the end of the docking arm 37 via mounting bolts 33. The clamping plate 382 is positioned by the bearing column 381, and the support plate 383 is fitted onto the trapezoidal sleeve block 9 of the clamping plate 382 via a sleeve groove, and can slide along the sleeve block 9. The upper and lower sets of electric push rods 384 of the clamping plate 382 output telescopic power, respectively driving the corresponding support plate 383 to slide, and relying on the upper and lower support plates 383 to lift and clamp the edge of the plate. One set of electric push rods 384 can be driven independently to enable a single support plate 383 to work independently, thereby supporting the plate or the lower wall of the door and achieving unobstructed detection of the upper wall.

[0040] More specifically, the bearing column 381 is bolted and detachable, facilitating the disassembly, assembly, maintenance, and replacement of the bearing unit 38; the trapezoidal sleeve block 9 cooperates with the sleeve groove to limit and guide the support plate 383, ensuring smooth sliding of the support plate 383 and preventing the support plate 383 from shifting or falling out; the electric push rod 384 drives the support plate 383 to automatically clamp the plate, automating the clamping action; it supports simultaneous operation of the upper and lower support plates 383, and can also use a single set of support plates 383 independently, adapting to different thicknesses of plates. The clamping method can also be switched when the plate is flipped, reducing the blind spot on the upper wall during inspection and ensuring the normal operation of laser and camera inspection.

[0041] As a preferred embodiment, the detection structure 4 includes a third electric slide rail 41, a detection frame 42, a fourth electric slide rail 43, a second hydraulic cylinder body 44, a lifting column 45, a lifting frame 46, a camera 47, several sets of boxes 48, several series frames 49, and several laser rangefinders 40. The third electric slide rail 41 is fixedly mounted on the right end of the base 1 and is perpendicular to the first electric slide rail 22. One end of the detection frame 42 is fixedly mounted on the third slider of the third electric slide rail 41, and the other end of the detection frame 42 is located above the middle of a pair of clamping structures 3. The detection frame 42 can move to the rear side of the clamping structure 3. The fourth electric slide rail 43... 3. Fixedly mounted on the other end of the detection frame 42, and the fourth slider on the fourth electric slide rail 43 is located below and moves left and right. One end of the second hydraulic cylinder body 44 is fixedly mounted on the fourth slider of the fourth electric slide rail 43. One end of the lifting column 45 is fixedly mounted on the fourth slider and located on the front side of the second hydraulic cylinder body 44. The lifting frame 46 is Z-shaped, with one end fixedly mounted on the telescopic end of the second hydraulic cylinder body 44, and the other end of the lifting frame 46 is movably fitted onto the lifting column 45. The camera 47 is fixedly mounted on the lower wall of one end of the lifting frame 46 and located on the rear side of the second hydraulic cylinder body 44. Several sets of boxes 48 can be connected in series. The components are interconnected and can be arranged alternately. One housing 48 is detachably mounted on the other end of the lifting frame 46. Several series frames 49 are connected at both ends to the housings 48 and are fixed by a third bolt. Several laser rangefinders 40 are detachably mounted inside the housings 48, with the camera direction of the laser rangefinders 40 facing downwards and opposite to the clamping structure 3. The third electric slide rail 41 is perpendicular to the first electric slide rail 22, which drives the detection frame 42 to move back and forth, allowing the detection frame 42 to move above or behind the clamping structure 3. The fourth electric slide rail 43 drives the fourth slider to achieve the lateral movement of the detection component. The movement increases the detection range; the second hydraulic cylinder body 44 drives the Z-shaped lifting frame 46 to move vertically up and down along the lifting column 45, and the lifting column 45 guides and limits the lifting frame 46; the lifting frame 46 is equipped with a camera 47 and multiple sets of boxes 48 assembled by splicing the series frame 49, and a laser rangefinder 40 is installed inside the box 48; the boxes 48 can be arranged in a straight line or staggered front and back to adjust the spacing of each laser rangefinder 40; the camera 47 and the laser rangefinder 40 follow the detection frame 42 and the lifting frame 46 to complete multi-dimensional displacement, and collect appearance images and flatness distance data of the plate clamped below.

[0042] More specifically, the detection mechanism achieves two-dimensional movement in both forward and backward and left and right directions through the third electric slide rail 41 and the fourth electric slide rail 43, and achieves vertical lifting and lowering in conjunction with the second hydraulic cylinder body 44. The detection actuator has a high degree of freedom of movement and can traverse the entire surface of the board. The Z-shaped lifting frame 46, guided by the lifting column 45, ensures smooth lifting and lowering, avoids swaying during the lifting process, and ensures the stability of the detection benchmark of the camera 47 and the laser rangefinder 40, thereby improving the accuracy of the detection data. The housing 48 can be flexibly spliced ​​with the help of the series frame 49, supporting straight or staggered arrangement, and can freely adjust the spacing of the laser rangefinder 40 points, taking into account the needs of large-area rapid scanning and high-density measurement point detection in local areas. The camera 47 and the laser rangefinder 40 are integrated on the same lifting frame 46, and the appearance photography and flatness detection are completed simultaneously in one movement. The detection frame 42 can be moved to the rear of the clamping structure 3 to adapt to the double-sided detection operation after the board is flipped.

[0043] As a preferred option, the other end of the lifting frame 46 can also be detachably fitted with a lower pressure arm 5 for pressure resistance testing; the housing 48 can be arranged alternately in front and behind or in a straight line to adjust the spacing of the laser rangefinder 40, thereby increasing the density of the detection points; the spacing of the bearing units 38 can be adjusted by connecting the adapter arm 34 and the adapter rod 35, thereby adjusting the detection length or width; the tray 383 in the bearing unit 38 can be switched to be used alone to fit different thicknesses of plates and surfaces.

[0044] Working principle:

[0045] The equipment uses base 1 as the mounting base for all components. A flip structure 2 is arranged on the left end of base 1. The base 21 is fixed on base 1. One side flip component 23 is installed on base 21, and the other side flip component 23 is installed on the slider of the first electric slide rail 22. The distance between the two sets of flip components 23 is adjusted by sliding the first electric slide rail 22, so as to adapt to wooden door panels of different widths.

[0046] When the flipping assembly 23 is working, the flipping frame 231 provides a mounting base for the other parts. The cylinder seat 232 fixes the first hydraulic cylinder body 233 to the side wall of the flipping frame 231. The first hydraulic cylinder body 233 outputs power to drive the limit frame 234 to make linear reciprocating motion along the lifting groove 6 opened in the flipping frame 231. The limit frame 234 synchronously drives the rack 235 to move. The rack 235 and the gear 237 mesh with each other, converting the linear driving force of the first hydraulic cylinder body 233 into rotational power. The gear 237 drives the drive shaft 236 to rotate in the bearing of the flipping frame 231. The drive shaft 236 outputs rotational power, driving the entire clamping structure 3 to complete the flipping action and realize the plate reversal.

[0047] The clamping structure 3 is assembled on the output end of the drive shaft 236 and rotates with the drive shaft 236. The housing of the second electric slide rail 31 is fixed on the drive shaft 236. The second electric slide rail 31 drives the second sliders on both sides, causing a pair of mounting seats 32 to move in opposite directions to adjust the clamping base spacing. The adapter arm 34 is inserted into the mounting port 7 of the mounting seat 32 and locked by tightening the mounting bolt 33. Multiple adapter arms 34 are connected by the adapter rod 35 passing through the adapter hole 8. The adapter bolt 36 is then tightened to press the adapter rod 35 to achieve splicing and fixation. The extension length of the clamping frame can be changed by increasing or decreasing the number of spliced ​​adapter arms 34. The docking arm 37 connects the adapter arm 34 and the bearing unit 38. The bearing unit 38 is detachably fixed to the end of the docking arm 37 by means of the mounting bolt 33.

[0048] During the operation of the bearing unit 38, the bearing column 381 serves as a connecting carrier, and the clamping plate 382 is fixed to the end of the bearing column 381. The trapezoidal sleeve block 9 set on the clamping plate 382 cooperates with the sleeve groove of the support plate 383 to form a sliding limit for the support plate 383. The electric push rods 384 symmetrically arranged on the upper and lower sides of the clamping plate 382 drive the support plate 383 to slide along the sleeve block 9. It is possible to select two sets of support plates 383 to operate simultaneously or to use a single set of support plates 383 to lift and clamp the edge of the plate. The clamping force is applied through the clamping plate 382 to complete the positioning and fixing of the plate. During the flipping operation, the plate clamping state is kept stable and the support plate 383 can be interchanged for bearing.

[0049] A detection structure 4 is set at the right end of the base 1. The third electric slide rail 41 is arranged perpendicularly to the first electric slide rail 22, driving the detection frame 42 to move back and forth. The detection frame 42 can move to the top of the plate for detection or to the rear of the clamping structure 3 to achieve comprehensive detection along plates of different lengths. The fourth electric slide rail 43 on the detection frame 42 drives the slider to achieve the left and right lateral movement of the detection component. The fourth slider is equipped with the second hydraulic cylinder body 44 and the lifting column 45. The second hydraulic cylinder body 44 drives the Z-shaped lifting frame 46 to achieve vertical lifting along the lifting column 45. The lifting column 45 guides and constrains the lifting frame 46. A camera 47 is installed on the lower side of the lifting frame 46. The other end of the lifting frame 46 can be detachably equipped with a matching box 48. Multiple boxes 48 are assembled in series by the connecting frame 49 and the third bolt. The boxes 48 can be arranged in a straight line or staggered front and back to achieve the detection spacing and range, and cooperate with the fourth electric slide rail 43 to achieve comprehensive detection without blind spots.

[0050] A laser rangefinder 40 is installed inside the housing 48; the entire testing system can perform multi-dimensional movements in front and back, left and right, and lifting. The camera 47 collects images of the board's appearance, and the laser rangefinder 40 measures downwards to collect data on the board's flatness. When a pressure test is required, the housing 48 and the laser rangefinder 40 are removed, and a lower pressure arm 5 is installed on the lifting frame 46. The lower pressure arm 5 presses down with the lifting frame 46 to apply pressure to the already fixed board and test the board's deformation under pressure.
