Description

Technical Field

[0001] The present disclosure relates to the field of detection technology, and in particular to a device for detecting plate materials. Background Art

[0002] In some assembly line operations, workpieces need to be turned over. For example, when conveying a sheet of material, the sheet needs to be turned over to perform operations on both sides, such as inspecting the surface quality.

[0003] Some panels are large and heavy, so one side can be worked on first, but working on the other side is inconvenient. Traditionally, this involves manual flipping or the use of equipment like cranes. Manual flipping is not only costly and difficult, but can also cause the panel to drop or dent during the flipping process, impacting the panel's quality.

[0004] It is hoped that at least one of the problems of traditional manual panel turning, such as high labor cost, inconvenient operation, and easy damage to the panel, can be solved. Summary of the Invention

[0005] An embodiment of the present disclosure provides an apparatus for detecting plates, the apparatus comprising: a flipping mechanism, the flipping mechanism comprising at least one clamping groove structure circumferentially arranged around a rotation axis, the two side wall portions of the clamping groove structure being suitable for placing the plate, the bottom wall portion of the clamping groove structure being used to press against the plate radially along the rotation axis, the clamping groove structure having a first horizontal position and a second horizontal position; two conveying mechanisms, the respective bearing surfaces of the two conveying mechanisms corresponding to the clamping groove structure in the first horizontal position and the clamping groove structure in the second horizontal position, respectively; and two identification platforms, respectively corresponding to the two conveying mechanisms, the identification platforms comprising a photographing device, the photographing device being used to photograph the surface of the plate on the corresponding bearing surface.

[0006] The device for inspecting sheet materials disclosed herein can flip a sheet material facing up from its first side to its second side during transport. The conveyor mechanism and the flipping mechanism securely interface, ensuring smooth sheet material transfer. The flipping mechanism's clamping grooves stably restrain the sheet material as it rotates between its first and second horizontal positions. The device can stably and reliably flip the sheet material. The device can also capture images of both sides of the sheet material to identify its surface condition, thereby facilitating sheet material sorting.

[0007] In some embodiments, the conveying direction of the conveying mechanism is perpendicular to the rotation axis.

[0008] With such an arrangement, the plate can be fed into the clamping groove structure of the flip mechanism more smoothly, and the plate can also be taken out from the clamping groove structure of the flip mechanism more smoothly.

[0009] In some embodiments, the clamping groove structures are spaced apart from the conveying mechanism along the conveying direction. When the clamping groove structures are in the first or second horizontal position, the spacing between the clamping groove structures and the corresponding conveying mechanism is less than the length of the sidewalls along the conveying direction. The spacing between the two sidewalls is configured to be 5 mm to 10 mm greater than the thickness of the plate when the clamping groove structures are in the second horizontal position. Exemplarily, the radial length of the sidewalls is 40% to 60% of the length of the plate. Exemplarily, the spacing between the two sidewalls is configured to be 10 mm to 15 mm.

[0010] This arrangement ensures reliable sheet material transfer and helps prevent bending. The clamping groove structure provides stable and reliable sheet material restraint. The length of the sidewall is roughly half the sheet material's dimension along the transfer direction, facilitating both transfer of sheets. The spacing between the two sidewalls effectively restrains the sheet material, preventing it from bumping during transfer and preventing scratches during transfer.

[0011] In some embodiments, the side wall portion of the clamping groove structure includes at least two clamping jaws spaced apart from each other. Exemplarily, along the rotation axis, the size of the bottom wall portion is 50% to 80% of the size of the plate.

[0012] With this arrangement, the clamping groove structure has a lighter weight, can reduce the contact area between the side wall and the plate, and can reduce the contact area between the bottom wall and the plate by configuring the bottom wall.

[0013] In some embodiments, there are multiple clamping groove structures; the flip mechanism includes multiple support rods, and the support rods are used to support two adjacent clamping groove structures.

[0014] This arrangement facilitates continuous and cushioned panel turnover and is easy to use. Multiple support rods enhance the structural strength of the clamping groove structure, making it more suitable for heavy panels and extending the service life of the equipment.

[0015] In some embodiments, the identification platform includes a slide rail and a shooting bracket, the shooting bracket is adjustably connected to the slide rail, the adjustment direction is perpendicular to the bearing surface, and the shooting device is connected to the shooting bracket.

[0016] With this arrangement, the position of the camera bracket along the slide rail can be adjusted according to the shooting requirements, thereby adjusting the distance between the camera and the supporting surface. The camera can take a good picture of the surface of the plate.

[0017] In some embodiments, the imaging device includes multiple line scan cameras or multiple area array cameras.

[0018] This setting can efficiently capture the plate and help identify defects in the plate in a targeted manner.

[0019] In some embodiments, the identification platform includes a plurality of adjustment legs connected to the slide rail.

[0020] With this arrangement, the horizontality of the entire photographing device relative to the conveying mechanism can be adjusted.

[0021] In some embodiments, the equipment for detecting the plate also includes a first drive device, a second drive device, a third drive device and a controller; the first drive device is used to drive the clamping groove structure to rotate from a first horizontal position to a second horizontal position; the second drive device and the third drive device are respectively used to drive the respective bearing surfaces of the two conveying mechanisms; the controller is used to control the first drive device, the second drive device and the third drive device.

[0022] With such an arrangement, the controller can be used to control each driving device, so that the equipment for detecting the plate can operate effectively and automatically, continuously and stably realize the turning over of the plate, and realize the processing of the plate.

[0023] In some embodiments, the shooting device includes multiple line scan cameras; the second drive device and the third drive device are stepper motors respectively, or the second drive device and the third drive device are respectively used to control the corresponding carrying surface movement speed to adapt to the line scan speed of the corresponding line scan camera.

[0024] Such a setting is conducive to the line scan camera capturing high-quality images and is beneficial for inspecting the plate.

[0025] In some embodiments, the device for detecting the plate also includes a sensing device, which is arranged in the corresponding clamping groove structure, and the sensing device can be triggered by the plate installed in the corresponding clamping groove structure; the controller is configured to: in response to the sensing device being triggered, control the first driving device to rotate the corresponding clamping groove structure around the rotation axis.

[0026] Such an arrangement helps to improve the flipping efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] See Figure 1 , Figure 1 The apparatus for detecting plate materials according to an embodiment of the present disclosure is shown. The apparatus 100 for detecting plate materials provided in the embodiment of the present disclosure includes a plate turning mechanism 1 and two conveying mechanisms 2. The apparatus 100 for detecting plate materials may include more conveying mechanisms 2 or more plate turning mechanisms 1.

[0044] Figure 1 The two conveying mechanisms 2 are connected by the plate turning mechanism 1 to form an assembly line. The device 100 for inspecting plates according to the embodiment of the present disclosure can be combined with other devices to realize a production line, an inspection line, or a screening line with richer functions.

[0045] Combine Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the flap mechanism 1 includes at least one clip groove structure 110, which is arranged circumferentially around the rotation axis. The clip groove 101 opens outward. The rotation axis of the clip groove structure 110 is parallel to the Y-axis. For example, the Z-axis is the vertical direction in space, and the XY plane is approximately horizontal. The rotation axis is arranged along the horizontal plane.

[0046] The clamping groove structure 110 rotates in the XZ plane. Along the X-axis direction, the clamping groove structure 110 can rotate from the right to the left, and also from the left to the right. Figure 1 From the perspective shown, the clamping groove structure 110 can rotate counterclockwise around the rotation axis. In other embodiments, the clamping groove structure 110 can rotate repeatedly in the upper semicircular area.

[0047] The clamping groove structure 110 has a first horizontal position and a second horizontal position. The clamping groove structure 110 in the first horizontal position can point to Figure 1 The right side of the clamping groove structure 110 in this state is directed to the right along the X-axis direction. The clamping groove structure 110 in the second horizontal position can point to Figure 1 In the left side of the figure, the clamping groove 101 of the clamping groove structure 110 in this state faces the left side along the X-axis direction.

[0048] The plate 200 is suitable for being placed between the two sidewalls 111 of the slot structure 110. Figure 1 and Figure 2, a clamping groove structure 110 is in an upper vertical position, and when the clamping groove structure 110 rotates from the first horizontal position on the right side to the upper vertical position, the right side wall portion 111 is used to press against the plate 200 along the circumferential direction. When the clamping groove structure 110 rotates from the upper vertical position to the second horizontal position on the left side, the left side wall portion 111 is used to press against the plate 200 along the circumferential direction. The bottom wall portion 120 of the clamping groove structure 110 is used to press against the plate 200 along the groove depth direction of the clamping groove 101. For example, the groove depth direction of the clamping groove 101 is radially along the axis of rotation. Since the clamping groove structure 110 can stably rotate around the axis of rotation, the plate 200 can be unrestricted on both sides of the clamping groove 101 along the Y-axis direction.

[0049] The two transmission mechanisms 2 are connected to the flap mechanism 1 respectively. Figure 6 The carrying surface 201 of the conveyor mechanism 2 can be substantially parallel to the XY plane. The carrying surface 201 can move along the X-axis to transport and transfer the plate 200. The plate 200 can be placed on the carrying surface 201 with the plate thickness direction along the Z-axis. Exemplarily, the carrying surface 201 is the top surface of the conveyor belt.

[0050] like Figures 1 to 3 As shown, in the embodiment of the present disclosure, the two conveying mechanisms 2 may include a first conveying mechanism 21 and a second conveying mechanism 22. The first conveying mechanism 21 is located on the right side of the flipping mechanism 1, and the first conveying mechanism 21 may be connected to the upstream of the flipping mechanism 1. The second conveying mechanism 22 is located on the left side of the flipping mechanism 1, and the second conveying mechanism 22 may be connected to the downstream of the flipping mechanism 1. The bearing surface 201 of the first conveying mechanism 21 corresponds to the clamping groove structure 110 in the first horizontal position, so as to transfer the plate 200 on the bearing surface 201 to the clamping groove structure 110 in the first horizontal position. The bearing surface 201 of the second conveying mechanism 22 corresponds to the clamping groove structure 110 in the second horizontal position, so as to take out and convey the plate 200 in the clamping groove structure 110 in the second horizontal position.

[0051] The apparatus 100 for inspecting a plate material according to an embodiment of the present disclosure is capable of conveying a plate material 200, and during the conveying process, different sides of the plate material 200 can be directed upward. The apparatus 100 for inspecting a plate material facilitates performing operations on a first side of the plate material 200 from above, and also facilitates performing operations on a second side of the plate material 200 from above.

[0052] The apparatus 100 for inspecting a plate according to the embodiment of the present disclosure further includes two identification platforms 3. The apparatus 100 for inspecting a plate can be used to identify surface defects of the plate.

[0053] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 6, two recognition platforms 3 correspond to two conveying mechanisms 2 respectively. More recognition platforms 3 can be provided, for example, multiple recognition platforms 3 correspond to one conveying mechanism 2. For example, the first recognition platform 31 corresponds to the first conveying mechanism 21, and the second recognition platform 32 corresponds to the second conveying mechanism 22.

[0054] The identification platform 3 includes a photographing device 310. The photographing device 310 is used to photograph the surface of the plate 200 on the corresponding supporting surface 201. The photographing device 310 of the first identification platform 31 can photograph the plate 200 transferred by the first conveying mechanism 2, for example, photograph the first side of the plate 200. After the first side of the plate 200 is photographed, the plate 200 is conveyed to the flipping mechanism 1 by the first conveying mechanism 2. The flipping mechanism 1 flips the plate 200 and also transfers the plate 200 to the second conveying mechanism 2. When the plate 200 is on the second conveying mechanism 2, its second side faces upward. The photographing device 310 of the second identification platform 32 can photograph the second side. The device 100 for detecting plates can photograph both sides of the plate 200 to identify the surface state of the plate 200; this then helps to classify the plate 200.

[0055] After being manufactured, the sheet material 200 may have surface defects. The apparatus 100 for inspecting sheet materials provided in the disclosed embodiments can identify one side of the sheet material 200 and conveniently identify the other side. This apparatus 100 for inspecting sheet materials helps address the high cost and operational difficulties of manual identification. This apparatus 100 also helps address the potential for subjective misjudgment.

[0056] For example, the conveying direction of the conveying mechanism 2 is perpendicular to the axis of rotation. Specifically, the conveying direction of the conveying mechanism 2, which is also the direction of movement of its supporting surface 201, is parallel to the X-axis and perpendicular to the Y-axis, enabling smooth transfer of the sheet 200. The conveying mechanism 2 is reliably docked with the flipping mechanism 1. The bottom wall 120 of the flipping mechanism 1 can face the sheet 200; when either clamping groove structure 110 of the flipping mechanism 1 rotates between the first and second horizontal positions, the sheet 200 can be stably restrained and subsequently flipped.

[0057] The device 100 for inspecting plates can smoothly deliver the plates 200 into or take them out of the clamping groove 101 . The plate 200 is subjected to force in the XZ plane, avoiding force along the Y-axis direction.

[0058] In other embodiments, the conveying direction of the conveying mechanism may intersect with the rotation axis, and the clamping groove structure may be able to adapt to the posture of the plate.

[0059] For example, the bearing surface 201 of the conveying mechanism 2 can be continuous or discontinuous. The bearing surface 201 is used to support the bottom surface of the plate 200 and can provide a driving force, such as friction, to the plate 200.

[0060] Exemplarily, the bearing surface 201 of the conveying mechanism 2 may be wider than the clamping groove 101 ; or narrower.

[0061] In the exemplary embodiment, the clamping groove structure 110 is spaced apart from the conveying mechanism 2 along the conveying direction. When in the first or second horizontal position, the distance between the clamping groove structure 110 and the conveying mechanism 2 is less than the length of the sidewall portion 111. Specifically, the distance between the notch of the clamping groove 101 and the supporting surface 201 of the conveying mechanism 2 is less than the depth of the clamping groove 101. This ensures that the sheet material 200 can be reliably conveyed, helps prevent bending of the sheet material 200, and stably and reliably restrains the sheet material 200.

[0062] refer to Figure 5 , the length of the side wall portion 111 refers to the distance from its outermost end point for contacting the plate 200 to the bottom of the groove, i.e., the bottom limit block 1210, or the effective contact length. The portion of the side wall portion 111 that contacts the plate 200 can be in continuous contact or intermittent contact. The two side wall portions 111 can be of equal length or of unequal length. In the clamping groove structure 110, the length of the shorter side wall portion 111 (either one when equal length) can be considered to be equivalent to the groove depth of the clamping groove 101. The groove depth of the clamping groove 101 refers to the distance from the groove mouth to the bottom of the groove, i.e., the bottom limit block 1210.

[0063] The groove depth of the clamping groove structure 110 can be 40% to 60% of the dimension of the plate 200 along the transfer direction. Figure 5 In the upper clamping groove structure 110 along the Z-axis, the length of the sidewall portion 111 along the Z-axis is 40% to 60% of the length of the plate 200. For example, if the plate 200 measures 900 mm x 900 mm, the length of the plate 200 along the conveying direction can be considered to be 900 mm, and the width of the plate 200 along the direction perpendicular to the conveying direction can be considered to be 900 mm. The depth of the clamping groove 101 can be less than 450 mm, and the distance between the notch of the clamping groove 101 and the supporting surface 201 of the conveying mechanism 2 can be less than 450 mm.

[0064] The groove depth or the radial dimension of the sidewall portion 111 of the clamping groove 101 along the rotation axis is less than 50% of the length of the plate 200, causing the plate 200 to be tilted radially relative to the rotation axis within the clamping groove structure 110. Because the plate 200 is thinner than the clamping groove 101, the end of the plate 200 located outside the clamping groove 101, i.e., the end away from the rotation axis, will tilt downward. This position facilitates the transport of the plate 200 by the plate inspection device 100 and helps prevent scratches between the plate inspection device 100 and the plate 200.

[0065] In some embodiments, the two sidewalls 111 of the clamping groove structure 110 can move, for example, rotate circumferentially or slide approximately tangentially, to narrow the clamping groove 101. For example, the clamping groove structure 110 can clamp the plate 200, which helps prevent the plate 200 from moving or bumping when flipping.

[0066] For example, the distance between the two sidewalls 111 is configured to be 5 mm to 10 mm greater than the thickness of the sheet 200 when the clamping groove structure 110 is in the second horizontal position. In other embodiments, the distance between the two sidewalls 111 is configured to be 5 mm to 10 mm greater than the thickness of the sheet 200 when the clamping groove structure 110 is in the first horizontal position. This distance between the two sidewalls 111 effectively restrains the sheet 200, preventing scratches during transfer and bumps during flipping.

[0067] For example, the distance between the two sidewalls 111 is configured to be 10 mm to 15 mm. The apparatus 100 for inspecting a plate material can be used to convey and flip a plate material 200 having a thickness of 5 mm.

[0068] In some embodiments, when the clamping groove structure 110 is in the first horizontal position, the two sidewall portions 111 are opposite to each other along the Z-axis. The lower sidewall portion 111 is flush with or lower than the supporting surface 201 of the first conveying mechanism 21. The upper sidewall portion 111 can be flush with or higher than the top surface of the plate 200.

[0069] In some embodiments, when the clamping groove structure 110 is in the second horizontal position, the two side wall portions 111 are opposite to each other along the Z-axis direction. During the process of the clamping groove structure 110 rotating from the first horizontal position to the second horizontal position, the plate 200 can be overlapped on the supporting surface 201 of the second conveying mechanism 22. The lower side wall portion 111 is flush with or lower than the supporting surface 201 of the second conveying mechanism 22; the lower side wall portion 111 can also be slightly higher than the supporting surface 201 of the second conveying mechanism 22. The upper side wall portion 111 is higher than the top surface of the plate 200. Exemplarily, the upper side wall portion 111 is higher than the supporting surface 201 of the second conveying mechanism 22 by one plate thickness.

[0070] refer to Figure 1 、 Figure 3 and Figure 5 In some embodiments, the sidewall portion 111 of the clamping groove structure 110 includes at least two spaced apart clamping jaws 1110 , which reduces the weight of the clamping groove structure 110 . The spaced apart clamping jaws 1110 can reduce the contact area between the sidewall portion 111 and the plate 200 .

[0071] refer to Figure 5 Along the rotation axis, the size of the bottom wall portion 120 is 50% to 80% of the size of the plate 200, which helps ensure the accurate posture of the plate 200 and prevents it from deflecting. For example, the bottom wall portion 120 includes at least two bottom stoppers 1210 spaced apart along the Y-axis. The bottom stoppers 1210 can be fixed to the clamping jaws 1110.

[0072] In some embodiments, multiple clamping groove structures 110 are provided to facilitate continuous and buffered panel flipping. For example, the panel flipping mechanism 1 includes four clamping groove structures 110, with the angle between two adjacent clamping groove structures 110 being 90° along the circumference of the rotation axis. One clamping groove structure 110 is in a first horizontal position; another clamping groove structure 110 loaded with a plate 200 is in an upper vertical position; another clamping groove structure 110 loaded with a plate 200 is in a second horizontal position and is ready to be unloaded; and a fourth clamping groove structure 110 may be in a lower vertical position, having previously unloaded a plate 200 and ready to be rotated to the first horizontal position in the next step.

[0073] Exemplarily, the flap mechanism 1 includes a flap support 150. Each clamping groove structure 110 can be rotatably connected to the flap support 150 via a rotating shaft. The flap support 150 can be configured to adjust or control the position of the clamping groove structure 110 in a horizontal position relative to the bearing surface 201 of the conveying mechanism 2.

[0074] In some embodiments, the flap mechanism 1 includes a first drive device 130. The first drive device 130 can be a drive motor. The fixed end of the first drive device 130 can be fixed to the flap support 150, and the drive end is used to drive the clamping groove structure 110 to rotate. For example, a driven wheel is provided on the rotating shaft, such as a pulley or a gear, and the drive end of the first drive device 130 is connected to the driven wheel through a transmission chain, which can be a belt or a toothed belt, and then the power is connected to the clamping groove structure. The first drive device 130 moves smoothly and can also stop at a specified angle to ensure that the clamping groove structure 110 stops in a horizontal position or other position.

[0075] In other embodiments, the rotation axis can serve as the bottom wall of the clamping groove structure. In other embodiments, the clamping groove structure deviates from the rotation axis along the Z-axis direction when in a horizontal position.

[0076] Exemplarily, the flap mechanism 1 may further include a flap platform on which the flap support 150 and the first drive device 130 may be mounted.

[0077] Illustratively, the plate flipping mechanism 1 includes a plurality of support rods 140. The support rods 140 are used to support two adjacent clamping groove structures 110. The plurality of support rods 140 can enhance the structural strength of the clamping groove structure 110, making it more suitable for heavy plates and also increasing the service life of the device 100 for detecting plates.

[0078] The apparatus 100 for inspecting a plate according to the embodiment of the present disclosure can be used to transfer a nickel plate.

[0079] Nickel plate can be manufactured through nickel electrolytic deposition. Nickel electrolytic deposition involves using an insoluble anode and direct current to deposit nickel ions from a nickel sulfate or nickel chloride solution onto the cathode of an electrolytic cell as metallic nickel. During the production process in nickel electrolytic plants, defects such as porosity, granulation, ablation, and resolvation can occur on the nickel plates due to uneven metal concentrations in the electrolyte, poor metal contact leading to conductivity fluctuations, and impurities in the electrolyte. After the nickel plates leave the electrolytic cell, the plant requires manpower to classify the plates, categorizing them into Class I, Class II, and Class III based on surface defects. Nickel is a nonferrous metal with a silvery-white background. Consequently, nickel plate defects are numerous and randomly distributed, making identification challenging. Due to the diverse and uneven distribution of surface defects, manual classification is the primary method used in the industry. This process can be prone to subjective misjudgment and high labor costs.

[0080] In some embodiments, the identification platform 3 includes a slide rail 320 and a photographing bracket 330. The photographing bracket 330 is adjustably connected to the slide rail 320, and the adjustment direction is perpendicular to the supporting surface 201. The photographing device 310 is connected to the photographing bracket 330.
