Description

Technical Field

[0001] The present invention relates to the field of product detection, and in particular to a plate-shaped workpiece detection device and a detection method. Background Art

[0002] In the actual production process of thin and light plate-shaped workpieces, the plate surface of the thin and light plate-shaped workpieces is easily deformed, resulting in their shape contour accuracy being unable to meet the use requirements, and they can be regarded as scrap. However, some of the thin and light plate-shaped workpieces can be corrected by applying corrective force to their shape contours so that their shape contour accuracy meets the use requirements. Thin and light plate-shaped workpieces may have "fake scrap" situations where the shape contour accuracy cannot meet the use requirements but can be used normally after correction.

[0003] In order to recycle and reuse the thin and light plate-shaped workpieces that are fake scrap, in the prior art, the thin and light plate-shaped workpieces that have been determined to be deformed are often placed in a forming mold, and a corrective force is applied to the thin and light plate-shaped workpiece so that one plate surface of the thin and light plate-shaped workpiece is made to fit as closely as possible with the membrane surface of the forming mold, and a plug gauge is inserted into the fitting gap between the plate surface of the thin and light plate-shaped workpiece and the membrane surface of the forming mold. When the plug gauge can be inserted into the fitting gap, it can be considered that even after correction, the shape contour accuracy of the thin and light plate-shaped workpiece still cannot meet the use requirements, and it is real scrap and should be scrapped. When the plug gauge cannot be inserted into the fitting gap, it can be considered that after correction, the shape contour accuracy of the thin and light plate-shaped workpiece can meet the use requirements, and it is fake scrap and can be recycled. However, different correction forces will lead to different degrees of fit between the plate surface of the thin plate-shaped workpiece and the membrane surface of the forming mold, resulting in different detection and evaluation conclusions of the plug gauge for the fitting gaps generated by different correction forces, resulting in inaccurate detection and evaluation conclusions. At the same time, the plug gauge can only measure the edge of the fitting gap between the plate surface of the thin plate-shaped workpiece and the membrane surface of the forming mold, and the fitting conditions of other parts of the fitting gap cannot be detected and accurately evaluated at all. Summary of the invention

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature.

[0034] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] Figure 1 FIG. 1 shows a schematic structural diagram of a plate-shaped workpiece 100 provided in this embodiment. Figure 1 As shown, a plate-shaped workpiece 100 is placed in a forming mold, and a correction force is applied to the plate-shaped workpiece 100 so that one surface of the plate-shaped workpiece 100 is fitted as closely as possible to the forming mold. Different correction forces will result in different degrees of fit between the plate surface of the plate-shaped workpiece 100 and the film surface of the forming mold, resulting in different detection and evaluation conclusions of the plug gauge for the fitting gaps generated by different correction forces, and the detection conclusions are not accurate enough. Therefore, applying a set correction force to the plate-shaped workpiece 100 so that the outer contour of the plate-shaped workpiece 100 is corrected, and detecting the overall outer contour accuracy of the plate-shaped workpiece 100 after the plate-shaped workpiece 100 is corrected is the key to accurately evaluating whether the plate-shaped workpiece 100 is a fake scrap. The following is combined with Figures 1 to 5 The plate-shaped workpiece detection equipment and detection method provided by the present invention are introduced in detail.

[0036] Figure 2 FIG. 2 shows a schematic diagram of the structure of the plate-shaped workpiece detection device provided in this embodiment. Figure 1 to Figure 2As shown, the plate-shaped workpiece detection device provided in this embodiment is used to detect the outer contour of the plate-shaped workpiece 100, and includes a frame 1, a thrust device 2 and an outer contour detector. During detection, the plate-shaped workpiece 100 is placed vertically, with the first plate surface 101 and the second plate surface 102 on both sides, and the top surface and the bottom surface on the top. The frame 1 includes a base 11 and a stand 12, and the two stands 12 are arranged on the base 11 at intervals along the first horizontal direction, and the stand 12 can support the bottom surface of the plate-shaped workpiece 100. The thrust device 2 includes a thrust assembly 21 and a support assembly 22, and a plurality of thrust assemblies 21 are arranged on the base 11 at intervals along the first horizontal direction, and the thrust assembly 21 can apply a set thrust to the first plate surface 101 of the plate-shaped workpiece 100. A plurality of support assemblies 22 are arranged on the base 11 at intervals along a first horizontal direction, and the support assemblies 22 can support the second plate surface 102 of the plate-shaped workpiece 100, wherein the first plate surface 101 and the second plate surface 102 are two opposite plate surfaces of the plate-shaped workpiece 100. The contour detector is detachably connected to the base 11, and can detect the contour of the plate-shaped workpiece 100. It should be noted that the contour detector can be a contour detection device such as a laser tracker, a three-dimensional coordinate detection machine, etc., which can establish a three-dimensional coordinate system of the plate-shaped workpiece 100. Of course, other contour detection devices are also within the protection scope of this embodiment, and will not be described one by one here. In addition, the plate-shaped workpiece 100 is not only easy to deform, but also if other components such as ribs and beams are arranged on its plate surface, the position accuracy of the above components can also affect the detection and evaluation conclusion of whether the plate-shaped workpiece 100 is a fake scrap. For example, T-shaped ribs are also arranged on the second plate surface 102 of the plate-shaped workpiece 100. Whether the position accuracy of the T-shaped ribs meets the use requirements directly affects the detection and evaluation results of the outer contour of the plate-shaped workpiece 100. The outer contour detector can establish a three-dimensional coordinate system of the plate-shaped workpiece 100, so as to determine whether the position accuracy of the T-shaped ribs on the second plate surface 102 meets the use requirements, thereby determining whether the plate-shaped workpiece 100 is a fake scrap.

[0037] The plate-shaped workpiece detection device in this embodiment supports the bottom surface of the plate-shaped workpiece 100 through the stand 12, so as to detect the contour of the plate surface of the plate-shaped workpiece 100; a plurality of thrust assemblies 21 are arranged on the base 11 at intervals along the first horizontal direction, and the thrust assemblies 21 apply a set thrust to the first plate surface 101 of the plate-shaped workpiece 100; a plurality of support assemblies 22 are arranged on the base 11 at intervals along the first horizontal direction, and the support assemblies 22 support the second plate surface 102 of the plate-shaped workpiece 100, so as to apply a set correction force to the plate-shaped workpiece 100, thereby When checking whether multiple plate-shaped workpieces 100 are fake scraps in turn, the plate surface of each plate-shaped workpiece 100 can be subjected to the same magnitude of correction force, so that the degree of correction of each plate-shaped workpiece 100 is consistent, so that a unified plate-shaped workpiece 100 outer contour detection standard can be established to improve the accuracy of the outer contour detection and evaluation results of the plate-shaped workpiece 100; the outer contour of the plate-shaped workpiece 100 is detected by the outer contour detector, so that the overall outer contour of the plate-shaped workpiece 100 can be detected, thereby further improving the accuracy of the outer contour detection and evaluation of the plate-shaped workpiece 100.

[0038] Figure 3 FIG. 2 shows a schematic diagram of the structure of the thrust assembly 21 provided in this embodiment. Figures 1 to 3 As shown, the thrust assembly 21 includes a fixed frame 211, a lead screw 212, a thrust piece 213 and a rotating handle 214. The rotating shaft of the lead screw 212 is rotatably connected to the fixed frame 211, the thrust piece 213 is threadedly connected to the lead screw 212, and the rotating handle 214 is coaxially connected to the lead screw 212 and can rotate the lead screw 212 to make the thrust piece 213 away from or close to the first plate surface 101, so that when checking whether a plurality of plate-shaped workpieces 100 are fake scraps in sequence, the moving distance of the thrust piece 213 is controlled by controlling the rotation amplitude of the rotating handle 214, so that when checking whether a plurality of plate-shaped workpieces 100 are fake scraps in sequence, the thrust piece 213 can move the same distance so that the same position of the plate surface of each plate-shaped workpiece 100 can be subjected to the same magnitude of correction force.

[0039] Preferably, the thrust assembly 21 also includes a thrust detection member 216, which is fixedly connected to the thrust member 213 and can directly detect the thrust provided by the thrust member 213, thereby obtaining the correction force borne by the plate-shaped workpiece 100 undergoing contour correction, so that when checking whether multiple plate-shaped workpieces 100 are fake scraps in sequence, the correction force borne by a specific position of the plate-shaped workpiece 100 can be fed back and adjusted in real time, so that the same position of the plate surface of each plate-shaped workpiece 100 can be subjected to the same magnitude of correction force. Specifically, the thrust detection member 216 is a thrust sensor with a digital display, which can directly detect the thrust provided by the thrust member 213. Other detection elements that can measure and obtain the correction force borne by the plate-shaped workpiece 100 are also within the protection scope of this embodiment, and will not be described one by one here.

[0040] Continue as Figures 1 to 3 As shown, the thrust assembly 21 also includes a driving member 215, which is fixedly connected to the base 11, and the output end of the driving member 215 is connected to the fixed frame 211 and is used to drive the fixed frame 211 to move along the second direction, wherein the second direction is perpendicular to the first direction and parallel to the first plate surface 101 and the second plate surface 102, that is, the vertical direction, so that the position of the thrust member 213 in the second direction can be changed according to the actual deformation position of the plate-shaped workpiece 100, thereby adjusting the force position of the plate-shaped workpiece 100, so as to better correct the outer contour of the plate-shaped workpiece 100, so as to improve the accuracy of the outer contour detection and evaluation results of the plate-shaped workpiece 100. Specifically, the driving member 215 is a screw lifting platform with a rotating handle, and the staff can rotate the rotating handle to adjust the spatial position of the thrust member 213 in the second direction.

[0041] Continue as Figures 1 to 3As shown, the thrust assembly 21 includes at least two thrust pieces 213, and the at least two thrust pieces 213 are arranged at intervals along the second direction, so as to increase the contact area between the thrust assembly 21 and the second plate surface 102, that is, increase the contact area between the correction force and the second plate surface 102. When targeting a large-sized plate-shaped workpiece 100, a thrust assembly 21 with multiple thrust pieces 213 can be selected to better correct the outer contour of the plate-shaped workpiece 100 of the large gear. It is worth noting that the number of thrust pieces 213 possessed by the thrust assembly 21 can be 1, 2, 3, or even more. The staff can reasonably choose to use thrust assemblies 21 with different numbers of thrust pieces 213 according to the actual local deformation and size of the plate-shaped workpiece 100. That is, when correcting a plate-shaped workpiece 100, for a local position with a larger size of the plate-shaped workpiece 100, a thrust assembly 21 with 3 thrust pieces 213 can be selected, for a local position with a moderate size of the plate-shaped workpiece 100, a thrust assembly 21 with 2 thrust pieces 213 can be selected, and for a local position with a smaller size of the plate-shaped workpiece 100, a thrust assembly 21 with only 1 thrust piece 213 can be selected. To correct a plate-shaped workpiece 100, thrust assemblies 21 with 1, 2, 3, or even more thrust pieces 213 can be used simultaneously, as long as the thrust pieces 213 can reasonably correct the outer contour of the plate-shaped workpiece 100.

[0042] Figure 4 FIG. 2 shows a schematic diagram of the structure of the support assembly 22 provided in this embodiment. Figure 4 Combination Figure 1 to Figure 2 As shown, the support assembly 22 includes a base 221 and a support member 222, one end of the support member 222 is rotatably connected to the base 221, and the support member 222 can switch between a support position in which it supports the second plate surface 102 and an open position away from the second plate surface 102, so that when the support member 222 is located in the open position away from the second plate surface 102, the plate-shaped workpiece 100 can be quickly installed on the frame 1, so that the stand 12 can support the bottom surface of the plate-shaped workpiece 100, and then when the support member 222 switches to the support position, it can reliably support the second plate surface 102 of the plate-shaped workpiece 100, and when the outer contour detection of multiple plate-shaped workpieces 100 is performed in sequence, the plate-shaped workpiece 100 can be quickly disassembled and assembled to improve the work efficiency of the outer contour detection and evaluation of the plate-shaped workpiece 100.

[0043] continue Figure 4 Combination Figure 1 to Figure 2As shown, the support assembly 22 also includes a first positioning member 223, the first positioning member 223 is fixedly connected to the support member 222, and the second plate surface 102 is provided with a second positioning member 103. When the support member 222 is in the supporting position, the first positioning member 223 and the second positioning member 103 are positioned and matched, so that the relative position of the plate-shaped workpiece 100 relative to the plate-shaped workpiece detection device can be determined, so as to obtain a measurement reference, thereby improving the accuracy of the contour detection of the plate-shaped workpiece 100. Specifically, the first positioning member 223 has a pin hole, and the second positioning member 103 can be a pin hole, and the positioning pin can be inserted into the two pin holes at the same time to ensure the coaxiality of the two pin holes, so that the relative position of the plate-shaped workpiece 100 relative to the support member 222 can be determined, and then the relative position of the plate-shaped workpiece 100 relative to the plate-shaped workpiece detection device can be determined, so as to improve the detection accuracy of the contour of the plate-shaped workpiece 100. It is worth noting that the first positioning member 223 and the second positioning member 103 provided in this embodiment are not limited to pin hole positioning. Any other positioning methods that can determine the relative position of the plate-shaped workpiece 100 relative to the plate-shaped workpiece detection equipment are within the protection scope of this embodiment. For example, the first positioning member 223 is a positioning block, and the second positioning member 103 is a positioning groove. The positioning block and the positioning groove cooperate to determine the relative position of the plate-shaped workpiece 100 relative to the plate-shaped workpiece detection equipment, which will not be described one by one here.

[0044] Continue as Figure 4 Combination Figure 1 to Figure 2 As shown, the support assembly 22 further includes a locking member 224. When the support member 222 is in the supporting position, the locking member 224 can lock the relative position between the base 221 and the support member 222. The water curtain tube 21 is maintained in the supporting position to reliably support the second plate surface 102 of the plate-shaped workpiece 100. Specifically, the locking member 224 is a quick-release bolt. The base 221 is provided with a threaded hole. The quick-release bolt can pass through the support member 222 and be screwed into the threaded hole, thereby fixing the support member 222 and the base 221.

[0045] Continue as Figure 4 Combination Figure 1 to Figure 2As shown, the support assembly 22 also includes a limit member 225, which is fixed on the base 11 and can limit the maximum rotation angle of the support member 222 relative to the base 221, so that when the support member 222 is in the open position, the support member 222 can remain stationary at the maximum rotation angle position relative to the base 221, so that when the staff installs the plate-shaped workpiece 100 on the stand 12, the support member 222 is prevented from colliding with other components of the plate-shaped workpiece detection equipment, thereby preventing the support member 222 from being deformed due to the collision, resulting in it being unable to reliably support the plate-shaped workpiece 100, thereby reducing the difficulty for the staff to disassemble and assemble the plate-shaped workpiece 100, and correspondingly reducing the difficulty of detecting the outer contour of the plate-shaped workpiece 100. Specifically, the limiting member 225 is a support frame with a limiting groove. When the support member 222 is in a free position, it can be accommodated in the limiting groove of the support frame, thereby limiting the maximum rotation angle of the support member 222 relative to the base 221, so that the support member 222 remains stationary at the maximum rotation angle position relative to the base 221.

[0046] Figure 5 Shows Figure 1 A local enlarged schematic diagram of the middle point. Figure 5 Combination Figure 1 to Figure 2 As shown in FIG. 1 , the stand 12 includes a first support arm 121 and a second support arm 122. The first support arm 121 is fixed on the base 11, and contacts the bottom surface of the plate-shaped workpiece 100 to support the plate-shaped workpiece 100, so as to support the plate-shaped workpiece 100 to be in the position to be detected. The second support arm 122 is vertically connected to the first support arm 121, and the second support arms 122 of the two stands 12 respectively contact the two side surfaces of the plate-shaped workpiece 100 to limit the movement of the plate-shaped workpiece 100 in the first direction, thereby preventing the plate-shaped plate from moving in the first direction during the shape contour detection process of the plate-shaped workpiece 100, affecting the shape contour detection evaluation result of the plate-shaped workpiece 100, thereby improving the shape contour evaluation accuracy of the plate-shaped workpiece detection equipment.

[0047] Optionally, a gasket 123 of a certain thickness is sandwiched between the second support arm 122 and the side surface of the plate-shaped workpiece 100 with which it contacts. Therefore, when the distance between the two second support arms 122 is too large to reliably limit the movement of the plate-shaped workpiece 100 in the first direction, a gasket 123 of a certain thickness can be placed according to the gap between the second support arm 122 and the side surface of the plate-shaped workpiece 100 with which it contacts, so that the plate-shaped workpiece 100 is limited in position in the second direction and cannot move.

[0048] In some embodiments, the plate-shaped workpiece detection device further includes a target support 31, which is fixedly connected to the base 11 and serves as a measurement reference point. The contour detector can be detachably connected to the target support 31 so that when detecting different plate-shaped workpieces 100, the measurement reference points are the same, so that the detection variables of the contour can be better unified to improve the detection accuracy of the plate-shaped workpiece detection device. It is worth noting that at least two target supports 31 are provided on the base 11, so that multiple measurement reference points can be established to facilitate the contour detector to detect the contour of the plate-shaped workpiece 100. The number of target supports 31 can be 1, 2, 3, or even more, and the staff can reasonably set it according to the actual needs of the contour detection of the plate-shaped workpiece 100, which is not limited here. As for the specific position of the target support 31, the staff can reasonably set it according to the actual needs of the contour detection of the plate-shaped workpiece 100, as long as the contour of the plate-shaped workpiece 100 can be accurately detected, and it will not be repeated here.

[0049] This embodiment also provides a plate-shaped workpiece 100 detection method. Based on the plate-shaped workpiece detection device provided in this embodiment, the plate-shaped workpiece 100 detection method includes the following steps: S100, the plate-shaped workpiece 100 is placed vertically, and the bottom surface of the plate-shaped workpiece 100 is supported by the stand 12. S200, the support assembly 22 supports the second plate surface 102 of the plate-shaped workpiece 100, and the thrust assembly 21 applies a set thrust to the first plate surface 101 to correct the plate-shaped workpiece 100, wherein the first plate surface 101 and the second plate surface 102 are two opposite plate surfaces of the plate-shaped workpiece 100. S300, the outer contour detector is used to detect the outer contour of the plate-shaped workpiece 100. Through the above method, a set thrust can be applied to the plate-shaped workpiece 100, so that the plate surface of each plate-shaped workpiece 100 can be subjected to the same correction force. Therefore, when checking whether multiple plate-shaped workpieces 100 are fake scraps in turn, the correction degree of each plate-shaped workpiece 100 is consistent, so that a unified standard for detecting the outer contour of the plate-shaped workpiece 100 can be established, and the overall outer contour of the plate-shaped workpiece 100 can be detected, thereby further improving the accuracy of the outer contour detection and evaluation of the plate-shaped workpiece 100.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
