[0024] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0026] It can be understood that a conveyor is provided on the frame of the grinding machine, and the conveyor is a belt mechanism or a roller, and the conveying direction and length direction of the belt mechanism or the roller are the front-to-back direction, and the width direction of the belt mechanism or the roller is the left-to-right direction. The online thickness measuring device is arranged between the front and rear belts or between the front and rear rollers on the roller.
[0027] Reference Figures 1 to 3 The utility model discloses an online thickness measuring device, including a pad 100, a supporting plate 200, a supporting plate 300, a pressing plate 400 and an in-position sensor 500. The pad 100 is used to be connected to the frame of the grinder. The length direction of the pad 100 is the left-right direction and is perpendicular to the conveying direction of the conveying path of the grinder. The upper end surface of the pad 100 is not lower than the conveying plane of the conveying path; the supporting plate 200 can be lifted and lowered in front of the pad 100, and the upper end surface of the supporting plate 200 is a lower inclined surface with a lower front and a higher rear. 210, the lower inclined surface 210 is used to lift the rear end of the substrate so that the substrate can be moved to the upper end surface of the pad 100; the support plate 300 is connected to the frame and is located above the pad 100; the pressing plate 400 can be raised and lowered on the support plate 300 and is located directly above the pad 100, the pressing plate 400 can be lowered to press the substrate against the pad 100, and the in-position sensor 500 is connected to the support plate 300, and the in-position sensor 500 is located directly above the pad 100 to detect the thickness of the substrate on the pad 100.
[0028] When the conveyor conveys the substrate from front to back, the rear end of the substrate will be against the lower inclined surface 210, and then the support plate 200 rises to lift the rear end of the substrate. Under the guidance of the lower inclined surface 210, the rear end of the substrate straddles the pad 100, and then the pressing plate 400 descends and presses the substrate against the pad 100. The pressing plate 400 and the pad 100 clamp the substrate, and then the in-position sensor 500 detects the thickness of the substrate on the pad 100. Due to the arrangement of the support plate 200 and the lower inclined surface 210, the collision between the substrate and the pad 100 can be avoided, and the risk of damage to the substrate and the pad 100 can be reduced. The pressing plate 400 and the pad 100 can smoothly clamp the substrate, and the stopped moving substrate is conducive to improving the accuracy of thickness measurement.
[0029] It is understandable that the length direction of the pad 100, the pallet 200 and the support plate 300 are all left-right directions, and the two side surfaces of the pad 100 / pallet 200 / support plate 300 are respectively arranged forward and backward. There are multiple numbers of the pressing plates 400 and the in-place sensors 500, and one pressing plate 400 and one in-place sensor 500 form a group. The thickness measuring device has multiple groups of pressing plates 400 and in-place sensors 500, and the multiple groups of pressing plates 400 and in-place sensors 500 are distributed on the support plate 300 along the left-right direction, so that the thickness of multiple areas of the substrate can be measured synchronously.
[0030] The common components of the in-place sensor 500 on the market are not described in detail here.
[0031] See also Figure 2In some of the embodiments, the front end of the lower end surface of the pressing plate 400 is an upper inclined surface 410 which is higher at the front and lower at the back. The upper inclined surface 410 has a guiding function. The upper inclined surface 410 can guide the substrate with the rear end facing upward to the bottom of the pressing plate 400, thereby pressing the substrate against the upper end surface of the pad 100.
[0032] The rear end of the lower end surface of the pressing plate 400 is parallel to the upper end surface of the pad 100. The lower end surface of the pressing plate 400 is used to press the substrate against the upper end surface of the pad 100. The contact area between the rear end of the lower end surface of the pressing plate 400, the upper end surface of the pad 100 and the substrate is large, so that the pressing plate 400 and the pad 100 can clamp the substrate more stably.
[0033] See also Figure 2 In some of the embodiments, a avoidance hole is provided in the middle of the rear end of the lower end surface of the pressing plate 400, and the sensing end of the in-place sensor 500 faces downward and passes through the avoidance hole. The substrate is pressed down by the pressing plate 400 on the peripheral side of the area corresponding to the in-place sensor 500, so that the substrate is more stable in the area corresponding to the in-place sensor 500, which is conducive to the in-place sensor 500 to measure the thickness of the substrate.
[0034] The online thickness measuring device further includes a first lifting drive mechanism 600, which is connected to the support plate 300 or the frame, and the output end of the first lifting drive mechanism 600 is connected to the pressing plate 400, and the first lifting drive mechanism 600 drives the pressing plate 400 to rise and fall, and the first lifting drive mechanism 600 drives the pressing plate 400 to descend, so that the pressing plate 400 can press the substrate against the pad 100; the first lifting drive mechanism 600 drives the pressing plate 400 to rise, and the pressing plate 400 releases the substrate. The first lifting drive mechanism 600 can be a first cylinder.
[0035] See also Figure 1 and Figure 3 In some of the embodiments, a sliding plate 700 that can slide in the left and right directions is provided on the support plate 300, and the pressing plate 400 and the in-place sensor 500 are connected to the support plate 300 through the sliding plate 700. When the sliding plate 700 moves, the sliding plate 700 carries the pressing plate 400 and the in-place sensor 500 in a certain direction in the left and right directions to adjust the left and right positions of the pressing plate 400 and the in-place sensor 500, so that the pressing plate 400 and the in-place sensor 500 correspond to basically different areas, so that the pressing plate 400 can press down different areas of the substrate, and the in-place sensor 500 detects the thickness of different areas of the substrate.
[0036] In some of the embodiments, a guide rail 320 extending in the left-right direction is provided on the support plate 300 , and the sliding plate 700 is provided on the guide rail 320 . The guide rail 320 serves to limit and guide the sliding plate 700 .
[0037] See also Figure 2 A driving member 310 is also provided on the support plate 300, and the driving member 310 is connected to the sliding plate 700. The driving member 310 drives the sliding plate 700 to slide in the left and right directions, thereby adjusting the left and right positions of the sliding plate 700, the pressure plate 400 and the in-place sensor 500.
[0038] In some embodiments, the driving member 310 is a screw rod, which is rotatably disposed on the support plate 300 and is threadedly connected to the sliding plate 700. When the screw rod is rotated, the screw rod drives the sliding plate 700 to move in the left and right directions.
[0039] Specifically, a bearing seat is provided on the support plate 300, a bearing is provided on the bearing seat, and a screw is connected to the bearing seat through the bearing. The length direction of the screw is the left-right direction, a threaded seat is provided on the sliding plate 700, a threaded hole is provided on the threaded seat, the axial direction of the threaded hole is the left-right direction, one end of the screw is matched with the threaded hole, and the other end of the screw is provided with a handle, and the screw can be easily rotated by the handle.
[0040] See also Figure 2 and Figure 3 In some embodiments, a locking mechanism 800 is connected to the sliding plate 700. When the sliding plate 700, the pressure plate 400 and the in-place sensor 500 are moved to appropriate positions, the locking mechanism 800 locks the sliding plate 700 on the support plate 300, thereby fixing the positions of the sliding plate 700, the pressure plate 400 and the in-place sensor 500.
[0041] In some embodiments, the support plate 300 is provided with a guide hole 330, the length of the guide hole 330 extends in the left-right direction, the sliding plate 700 is provided on the front side of the support plate 300, and the locking mechanism 800 is slidably penetrated in the guide hole 330. When the sliding plate 700 carries the locking mechanism 800 and slides in the left-right direction, the locking mechanism 800 slides in the guide hole 330. The length of the guide hole 330 is the sliding stroke of the sliding plate 700 and the locking mechanism 800. The guide hole 330 defines the leftmost position and the rightmost position of the sliding plate 700 and the locking mechanism 800. When the sliding plate 700, the pressure plate 400 and the in-position sensor 500 are moved to a suitable position, the locking mechanism 800 is fixedly connected to the side wall of the guide hole 330, so that the locking mechanism 800 can closely attach the sliding plate 700 to the front side of the support plate 300.
[0042] See also Figure 2 and Figure 3 It can be imagined that the locking mechanism 800 is a second cylinder, one of the cylinder body of the second cylinder and the piston rod of the second cylinder passes through the guide hole 330 and is connected to the sliding plate 700, and the other abuts against the rear side of the support plate 300.
[0043] Specifically, the second cylinder is arranged at the rear of the support plate 300, and the cylinder body of the second cylinder is connected to multiple connecting rods 810. All the connecting rods 810 can be slidably passed through the guide holes 330 and connected to the sliding plate 700. All the connecting rods 810 are provided with the same pressure plate 820 that can move in the front and rear directions. The pressure plate 820 is arranged at the rear of the support plate 300, and the piston rod of the second cylinder can be against the pressure plate 820.
[0044] When it is necessary to lock the sliding plate 700, the second cylinder extends the piston rod, and the piston rod presses on the pressure plate 820, and the pressure plate 820 presses on the rear side of the support plate 300, so that the cylinder body retreats, and the cylinder body pulls the sliding plate 700 backward through the connecting rod 810, and the pressure plate 820 and the sliding plate 700 clamp the support plate 300, and the sliding plate 700 is tightly attached to the front side of the support plate 300; when it is not necessary to lock the sliding plate 700, the second cylinder retracts the piston rod, and the pressure plate 820 and the sliding plate 700 will no longer clamp the support plate 300, and the connecting rod 810 can continue to slide in the guide hole 330, that is, the sliding plate 700, the pressure plate 400 and the in-position sensor 500 can continue to slide in the left and right directions.
[0045] See also Figure 2 The guide rail 320 includes two limit plates, which are arranged on the front side of the support plate 300. The lengths of the two limit plates extend in the left-right direction. The two limit plates are arranged one above and one below. The front ends of the two opposite sides of the two limit plates are provided with flanges. Slide grooves are formed between the two flanges and the front side of the support plate 300, and the upper and lower ends of the sliding plate 700 extend into the two slide grooves.
[0046] In some of the embodiments, a guide member 110 is provided on the backing plate 100 , and the support plate 200 is connected to the backing plate 100 via the guide member 110 , and the guide member 110 is used to guide the support plate 200 to rise and fall.
[0047] Specifically, the guide member 110 is a bolt structure, and the guide member 110 has a nut, a plain rod and a threaded rod connected in sequence. A stepped through hole is opened on the support plate 200, and the length of the stepped through hole is in the up and down direction. The stepped through hole has a connected large end and a small end, and the large end and the small end are respectively arranged on the front side and the rear side of the support plate 200. The nut and the plain rod are respectively inserted into the large end and the small end, and the threaded rod is threadedly connected to the pad 100.
[0048] In some of the embodiments, the online thickness measuring device further comprises a second lifting drive mechanism 900, the second lifting drive mechanism 900 is connected to the frame or the backing plate 100, the output end of the second lifting drive mechanism 900 is connected to the support plate 200, and the second lifting drive mechanism 900 drives the support plate 200 to rise and fall. The second lifting drive mechanism 900 is a third cylinder.
[0049] It is understandable that the support plate 300 is connected to a guide plate 340 , which is located behind the pressing plate 400 , and the front end of the guide plate 340 is upturned, and the guide plate 340 can transfer the substrate with the upturned rear end downward.
[0050] The online thickness measuring device also includes a rotary encoder, which is connected to the roller of the conveyor to detect the rotation angle of the roller, thereby detecting the movement amount of the substrate conveyed by the conveyor, that is, detecting the distance of the substrate across the pad 100. When the distance of the substrate across the pad 100 reaches the thickness measuring position, the conveyor stops conveying the substrate, and the online thickness measuring device basically measures the thickness, detects the movement amount of the substrate conveyed by the conveyor, and then controls the start and stop of the conveyor, thereby realizing the control of the distance of the substrate across the pad 100.
[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0052] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention.
