Description

Technical Field

[0001] This utility model relates to the field of plate material inspection technology, and more specifically, it relates to a plate warpage detection device. Background Technology

[0002] After the slab material is processed, the surface flatness and warpage inspection is an essential quality inspection step. This inspection can accurately identify deformation problems that may occur during processing such as cutting, stamping, and heat treatment, effectively prevent unqualified slabs from flowing into subsequent processes, ensure that the slabs meet the requirements for subsequent assembly and use, and guarantee the assembly accuracy and reliability of the final product.

[0003] In existing testing technologies, the flatness and warpage of slab surfaces are often detected by scanning and collecting data at the testing end of the testing equipment. For example, a dial indicator used with a support can directly contact the surface of the slab through the testing end to capture height changes at different points. Alternatively, devices such as laser displacement sensors and laser profile scanners can be used to quickly collect key information such as surface profile shape and height difference without contacting the slab.

[0004] When scanning and inspecting large slabs, the inspection device needs to move the inspection end relative to the slab so that the inspection end covers the entire inspection area of ​​the slab. However, the movement of the slab and the movement of the inspection end often require two independent drive systems. This not only increases the equipment structure, but may also affect the inspection accuracy due to the inconsistency in the coordination of the two drive systems.

[0005] Therefore, in order to solve the above problems, we propose a slab warpage detection device. Utility Model Content

[0008] Furthermore, the circulation mechanism also includes a support frame and a power output component. The power output component can drive the movable frame to reciprocate along the longitudinal direction of the support frame, thereby driving the detection component to detect the surface of the slab.

[0009] Furthermore, linear guide rails are formed on both sides of the support frame, and the movable frame is slidably disposed within the guide rails via guide wheels on both sides.

[0010] Furthermore, the power output assembly includes a pulley drive assembly and a lever. One end of the lever is connected to the drive belt of the pulley drive assembly, and the other end is inserted into a limiting groove opened on the surface of the movable frame.

[0011] Furthermore, the limiting groove is opened along the length direction of the movable frame, and the length of the limiting groove is greater than the distance between the two branches of the transmission belt of the pulley drive assembly.

[0012] Furthermore, the linkage includes a drive rod located on one side at the end of the travel of the moving frame. The moving frame drives the drive member to rotate the transmission shaft by pushing the drive rod at the end of the travel.

[0013] Furthermore, the driving component includes a driving disk connected to one end of the transmission shaft and a ratchet toothed disk that cooperates with the driving disk to realize unidirectional rotation of the transmission shaft.

[0014] Furthermore, the axis of the ratchet disc coincides with the axis of the drive disc, and the drive disc is provided with a pawl on the side near the ratchet disc, the pawl being embedded in the gap between the ratchet teeth of the ratchet disc.

[0016] Furthermore, a connecting frame is provided on one side of the transmission rod, the transmission rod is slidably connected to the connecting frame, and an elastic element is provided on the connecting frame to reset the transmission rod.

[0018] This invention employs a linkage design, enabling the detection end of the detection component to move backward along the slab surface under the drive of the circulation mechanism to complete the detection, while simultaneously moving the slab forward. This avoids the structural complexity issues associated with using two independent drive systems, effectively reducing equipment complexity, saving production costs, and lowering the difficulty of future maintenance. Furthermore, this linkage method ensures the coordination between the movement of the detection component and the slab, avoiding the problem of inconsistent coordination between the two drive systems affecting detection accuracy, thus improving the accuracy and reliability of the detection.

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Please see the appendix Figure 1-9 A slab warpage detection device includes a support frame 1 for supporting the slab. The support frame 1 includes bases on both sides and several drive shafts 101 located between the bases. The two ends of the drive shafts 101 are rotatably connected to the bases. A conveyor belt 102 is sleeved on the surface of the drive shafts 101. The slab is placed on the surface of the conveyor belt 102 and moved under its drive. A drive mechanism 3 is provided at the end of one of the drive shafts 101. A detection component 4 and a circulation mechanism 2 that can drive the detection component 4 to circulate back and forth along the surface of the slab being detected are provided on the top of the conveyor belt 102. The detection component 4 can use a dial indicator, which directly contacts the surface of the slab through its detection end, and captures the height changes at different points under the drive of the circulation mechanism 2. Alternatively, a laser displacement sensor can be used, which irradiates the surface of the slab with a laser beam emitted by the sensor and uses the reflected light to measure the distance from different points on the slab surface to the sensor, thereby obtaining the contour information of the slab surface. The collected information is finally processed and analyzed to determine the warpage of the slab.

[0034] like Figure 2 , 3 As shown, the circulation mechanism 2 includes a movable frame 201 connected to the detection component 4 and a support frame 202 located at the top of the support frame 1. The movable frame 201 drives the detection component 4 connected to its bottom end to reciprocate along the longitudinal direction of the support frame 202, thereby detecting the surface of the slab.

[0035] The drive mechanism 3 includes a drive component that drives the transmission shaft 101 to rotate in one direction and a linkage component located on one side of the moving frame 201 that cooperates with the drive component. In the working state, the moving frame 201 applies driving force to the linkage component by impact during the displacement stroke. Through the power transmission of the linkage component, the drive component drives the transmission shaft 101 on one side to rotate. The transmission shaft 101 located on one side of the drive component starts to rotate as the active shaft, causing the slab placed on the surface of the conveyor belt 102 to move forward and approach the detection component 4.

[0036] The drive mechanism 3 is preferably located on one side of the drive shaft 101 at one end of the support frame 1. The slab moves forward stably through the friction between the drive shaft 101 and the conveyor belt 102. To avoid slippage between the drive shaft 101 and the conveyor belt 102, anti-slip textures can be provided on the inner surface of the conveyor belt 102, or anti-slip protrusions can be provided on the surface of the drive shaft 101 to increase the friction between the two.

[0037] The relative movement between the detection component 4 and the slab is achieved by the driving force provided by the circulation mechanism 2, enabling the detection component 4 to detect different areas of the slab. While reducing the structure of the corresponding driving equipment, the linkage effect between the two allows the slab to move forward a certain distance in time after the detection component 4 completes one stroke driven by the circulation mechanism 2, so that the detection component 4 can perform the next detection. This avoids the possibility of missing some areas due to the inconsistency of the coordination between the two independent driving systems, thereby improving the accuracy of detection.

[0038] like Figure 5 As shown, the circulation mechanism 2 also includes a power output component that can drive the movable frame 201 to reciprocate along the longitudinal direction of the support frame 202. The power output component includes a pulley drive assembly 203 and a lever 205. The pulley drive assembly 203 consists of two drive wheels rotatably connected to the top wall of the support frame 202 and a drive belt sleeved on the surface of the two drive wheels. The shaft of one drive wheel is connected to an output motor, which drives the pulley drive assembly 203 through the output end of the output motor. One end of the lever 205 is connected to a branch on one side of the drive belt of the pulley drive assembly 203, and the other end is inserted into a limiting groove opened on the surface of the movable frame 201. The limiting groove is opened along the length of the movable frame 201, and the length of the limiting groove is greater than the distance between the two branches of the drive belt of the pulley drive assembly 203, so that the lever 205 can slide smoothly in the limiting groove under the drive of the drive belt.

[0039] When the pulley drive assembly 203 is running, the drive belt drives the actuating rod 205 to perform a circular reciprocating motion. Through the engagement of the actuating rod 205 with the limiting groove of the moving frame 201, the actuating rod 205, while completing the cyclic reciprocating motion, pushes the moving frame 201 to perform a reciprocating linear motion along the longitudinal direction of the support frame 202.

[0040] like Figure 4 As shown, linear guide rails are formed at the bottom of both side walls of the support frame 202. The movable frame 201 is slidably set in the guide rails by guide wheels on both sides. The length of the linear guide rails is greater than the width of the support frame 1, which is also greater than the width of the slab to be inspected. This avoids the situation where the moving range of the movable frame 201 cannot fully cover both sides of the slab, thus preventing the omission of the inspection area.

[0041] like Figure 6 , 7 As shown, the linkage includes a drive rod 302 located on one side of the stroke end of the movable frame 201. The drive rod 302 is vertically arranged, and its top end is located at the end of the reciprocating stroke of the movable frame 201. When the movable frame 201 moves to the side of the drive rod 302 under the drive of the pulley transmission group 203, it will push the drive rod 302. After the top of the drive rod 302 is pushed and squeezed, the drive member drives the transmission shaft 101 to rotate through power transmission.

[0042] like Figure 8 , 9 As shown, the driving component includes a driving disk 301 fixedly connected to one end of the transmission shaft 101 and a ratchet disk 309 that cooperates with the driving disk 301 to realize the unidirectional rotation of the transmission shaft 101. The axis of the ratchet disk 309 coincides with the axis of the driving disk 301. A pawl 305 is provided on the side of the driving disk 301 near the ratchet disk 309. There is a gap between the ratchet disk 309 and the driving disk 301. The two are in contact only through the pawls 305 on both sides of the driving disk 301. One end of the pawl 305 is connected to the driving disk 301 through a connecting rod. One end of the connecting rod is fixed to the surface of the driving disk 301, and the other end is rotatably connected to the pawl 305. The end of the pawl 305 away from the connecting rod is embedded in the ratchet gap of the ratchet disk 309, and an elastic component is provided on one side of the pawl 305 to make it fit against the surface of the ratchet disk 309.

[0043] When the ratchet disc 309 rotates clockwise, the pawl 305 will get stuck in the gap between the ratchet teeth of the ratchet disc 309, thereby driving the drive disc 301 and the transmission shaft 101 to rotate together. When the ratchet disc 309 rotates counterclockwise, the pawl 305 will slide on the ratchet teeth and will not drive the drive disc 301 to rotate, thus realizing the unidirectional rotation of the transmission shaft 101. The unidirectional rotation of the transmission shaft 101 makes the conveyor belt 102 and the slab always move in one forward direction.

[0044] The linkage also includes a transmission rod 304 that transmits the driving force from the drive rod 302 to the ratchet gear 309. A connecting frame 303 is provided on one side of the transmission rod 304. The connecting frame 303 is fixedly connected to the support frame 1. The transmission rod 304 is slidably connected to the connecting frame 303. A first gear 310 is fixedly connected to the bottom end of the drive rod 302 near the transmission rod 304. The first gear 310 is rotatably connected to the connecting frame 303 through a mounting seat. A second gear 307 is fixedly connected to the ratchet gear 309 near the transmission rod 304 through a coupling shaft. The coupling shaft passes through the second gear 307 and is rotatably connected to the connecting frame 303 through the mounting seat. A number of equidistantly distributed limiting grooves are opened on the transmission rod 304 near the second gear 307 and the first gear 310, respectively. The first gear 310 and the second gear 307 respectively mesh with the limiting grooves opened on the transmission rod 304.

[0045] When the moving frame 201 pushes the drive rod 302 to rotate at the end of its stroke, the drive rod 302 drives the first gear 310 to rotate. Since the first gear 310 meshes with the transmission rod 304, the rotation of the first gear 310 will cause the transmission rod 304 to slide downward along the connecting frame 303. During the downward sliding process, the transmission rod 304 will drive the second gear 307 meshed with it to rotate clockwise. The clockwise rotation of the second gear 307 will drive the ratchet disc 309 to rotate synchronously. Through the cooperation of the ratchet disc 309 and the pawl 305 on the drive disc 301, the drive disc 301 drives the transmission shaft 101 to rotate synchronously, and finally the conveyor belt 102 drives the slab to move forward.

[0046] When the moving frame 201 moves away from the drive rod 302, in order to reset the drive rod 302 and the transmission rod 304, an elastic element 311 is provided on the connecting frame 303 to reset the transmission rod 304 and the drive rod 302. A baffle is provided at the bottom end of the connecting frame 303 where the transmission rod 304 passes through the baffle. A limit ring is fixed to the outer wall of the transmission rod 304. The elastic element 311 is a spring sleeved on the outer wall of the transmission rod 304. The two ends of the spring abut against the limit ring and the bottom wall of the connecting frame 303, respectively. In the initial state, under the action of the elastic force of the elastic element 311, the limit ring is in contact with the baffle. At this time, the transmission rod 304 is at its highest position. When the moving frame 201 pushes the drive rod 302 to make the transmission rod 304 slide down, the elastic element 311 is compressed. When the moving frame 201 moves away from the drive rod 302 and no longer applies a pushing force to it, the elastic element 311 releases its elastic potential energy, pushing the limit ring to move upward, thereby causing the transmission rod 304 to slide upward and reset. At the same time as the transmission rod 304 resets, the first gear 310 and the second gear 307 meshing with it will also rotate in opposite directions at a certain angle, so that the drive rod 302 also resets and returns to its initial state, preparing for the next push by the moving frame 201.

[0047] Working principle: First, the slab is placed on the conveyor belt 102. Then, the output motor is started. The output end of the output motor drives the pulley transmission group 203 to run. The transmission belt of the pulley transmission group 203 drives the moving frame 201 to reciprocate linearly along the longitudinal direction of the support frame 202 through the actuating rod 205. The moving frame 201 drives the detection component 4 connected to its bottom end to detect the surface of the slab. When the moving frame 201 moves to the side of the drive rod 302 under the drive of the pulley transmission group 203, it will push the drive rod 302. After the top of the drive rod 302 is pushed and squeezed, it drives the first gear 310 to rotate. The rotation of the first gear 310 causes the transmission rod 304 to slide down along the connecting frame 303. During the downward sliding process, the transmission rod 304 drives the second gear 307 meshed with it to rotate clockwise. The clockwise rotation of the second gear 307 drives the ratchet disc 309 to rotate synchronously. The rotation, through the ratchet gear 309 engaging with the pawl 305 on the drive disc 301, causes the drive disc 301 to drive the transmission shaft 101 to rotate synchronously, ultimately causing the conveyor belt 102 to move the slab forward a certain distance. When the moving frame 201 moves away from the drive rod 302, the elastic element 311 releases its elastic potential energy, pushing the limit ring upward, thereby causing the transmission rod 304 to slide upward and reset. At the same time as the transmission rod 304 resets, the first gear 310 and the second gear 307 meshing with it will also rotate in opposite directions at a certain angle, causing the drive rod 302 to also reset and return to its initial state, preparing for the next push of the moving frame 201. This cycle repeats, and after the detection component 4 completes one stroke under the drive of the circulation mechanism 2, the slab can move forward a certain distance in time so that the detection component 4 can perform the next detection, until the warpage and surface flatness of the entire slab are detected.
