Description

Technical Field

[0001] The utility model relates to the technical field of glass detection, and more specifically, to a glass substrate foreign matter detection device. Background Art

[0002] On the glass production line, annealed molten glass flows continuously and at a uniform speed. Molding equipment then uses this naturally overflowing molten glass to combine into ultra-thin glass ribbons to create raw ultra-thin glass sheets. The glass then needs to be cut. After cutting, the edges and corners of the glass substrates need to be ground to improve edge strength. After each processing step, the glass substrates need to be inspected for foreign matter, including but not limited to dust, glass shavings, grease, and particulate matter. If any foreign matter is present, it needs to be cleaned. Only after cleaning can the cleaned glass substrates proceed to the next process and be packaged for transportation.

[0003] Existing glass substrate foreign body detection devices typically place a glass substrate flat on a testing table and use a laser to scan and detect it. When the laser beam hits the surface of the glass substrate, the foreign body will appear as a distinct dark spot or bright spot in the grayscale image due to varying degrees of reflection. By analyzing these dark spots or bright spots using image processing technology, the location and size of the foreign body can be determined. However, existing glass substrate foreign body detection devices typically require a worker to lift the glass substrate again, flip it over, and inspect the other side after inspecting one side of the glass substrate. This increases the worker's workload, reduces the efficiency of glass substrate foreign body detection, and increases labor costs. Utility Model Content

[0004] In order to solve the above problems in the prior art, the utility model provides a glass substrate foreign matter detection device.

[0005] According to one aspect of the present invention, a glass substrate foreign matter detection device is provided, comprising a support frame, a rotating rod rotatably mounted on the support frame, a connecting block fixedly mounted on the inner side of the rotating rod, connecting rods fixedly mounted on both sides of the connecting block, and the other end of the connecting rod is connected to a fixing device, which is used to fix the glass substrate between the support frames.

[0006] Through this solution, the glass substrate is installed between the two support frames through the fixing device, and the rotating rod is rotated to drive the rotation of the connecting block, thereby driving the fixing device to clamp the glass substrate and rotate it, so that the glass substrate can be quickly turned over, which greatly improves the efficiency of glass substrate turning over, reduces labor costs, and ensures the smooth progress of glass substrate foreign body detection work.

[0007] Preferably, the connecting rod comprises a first connecting rod and a second connecting rod, one end of the first connecting rod is fixedly connected to the connecting block, and the other end is sleeved on the second connecting rod and slidably connected to the second connecting rod.

[0008] Through this solution, the second connecting rod is slidably connected to the first connecting rod, and the position of the fixing device can be adjusted at any time according to glass substrates of different widths, meeting the clamping and fixing requirements of glass substrates of different widths, and has a wide range of applications.

[0010] With this solution, when the four corners of the glass substrate need to be clamped and fixed, the second connecting rod is pulled outward to fix the fixing device at the four corners of the glass substrate. At this time, the spring will exert an inward pulling force on the second connecting rod, thereby achieving a better clamping effect on the glass substrate. The provision of the positioning rod can play a good guiding role, enhance the rigidity of the connection between the second connecting rod and the first connecting rod, and prevent the second connecting rod from being separated from the first connecting rod, thereby affecting the clamping and fixing effect of the glass substrate.

The fixing block is fixedly connected to the second connecting rod. The front end of the fixing block is provided with the slot, and the slot is adapted to be engaged with the right-angled edge of the glass substrate. The tightening bolt passes through the groove wall at the top of the slot to press the glass substrate.

[0012] Through this solution, the four right-angled sides of the glass substrate are clamped with the corresponding clamping slots, and then the tightening bolts are used to further fix the glass substrate, which has a good fixing effect and enhances the stability of the glass substrate during detection.

[0013] Preferably, the transverse cross-section of the slot is L-shaped.

[0014] Through this solution, the L-shaped design fits in with the right-angled side of the glass substrate, which can better fix the four corners of the glass substrate and has a good fixing effect.

[0015] Preferably, a handle is vertically fixedly mounted on the outer end of the rotating rod, and a limiting component for limiting the position of the glass substrate is mounted on the handle.

[0016] According to this solution, when the glass substrate needs to be flipped, the handle is turned. After the glass substrate is flipped, the position of the handle is fixed by the limiting component, thereby completing the fixation of the position of the glass substrate. The operation method is simple and practical.

[0017] Preferably, the limiting component includes a limiting rod and a limiting hole, the supporting frame is respectively provided with the limiting holes directly above and directly below the rotating rod, and the limiting rod passes through the handle and is inserted into the corresponding limiting hole.

[0018] Through this solution, when the handle is rotated to the position of the corresponding limiting hole, the limiting rod is inserted into the limiting hole to perform the limiting operation, thereby quickly completing the limitation of the position of the glass substrate, so that the glass substrate is always on the horizontal plane before and after flipping, which is convenient for detecting foreign objects on the glass substrate.

[0019] Preferably, limit blocks are fixedly mounted on the limit rods on both sides of the handle.

[0020] Through this solution, the setting of the limit block can prevent the limit rod from being separated from the handle, thereby affecting the smooth progress of the limit work.

[0033] Example

[0034] like Figures 1 to 3 As shown, the glass substrate foreign matter detection device in this embodiment includes a support frame 1, and the number of the support frames 1 is two. A rotating rod 2 is rotatably installed on each of the two support frames 1. A connecting block 3 is fixedly installed on the inner side of the rotating rod 2. Connecting rods 4 are fixedly installed on both sides of the connecting block 3. The other end of the connecting rod 4 is connected to a fixing device 5, and the fixing device 5 is used to fix the glass substrate 6 between the support frames 1.

[0035] The glass substrate 6 is installed between the two support frames 1 through the fixing device 5, and the rotating rod 2 is rotated to drive the rotation of the connecting block 3, thereby driving the fixing device 5 to clamp the glass substrate 6 and rotate, which can quickly realize the turning operation of the glass substrate 6, greatly improving the efficiency of the glass substrate turning, reducing labor costs, and ensuring the smooth progress of the glass substrate foreign body detection work.

[0036] Furthermore, the connecting rod 4 includes a connecting rod 1 41 and a connecting rod 2 42 , one end of the connecting rod 1 41 is fixedly connected to the connecting block 3 , and the other end is sleeved on the connecting rod 2 42 and slidably connected to the connecting rod 2 42 .

[0037] The second connecting rod 42 is slidably connected to the first connecting rod 41, and the position of the fixing device 5 can be adjusted at any time according to the glass substrates 6 of different widths, meeting the clamping and fixing requirements for glass substrates 6 of different widths, and has a wide range of applications.

[0038] Furthermore, a slide groove 7 is opened inside the connecting rod 1 41, and the connecting rod 2 42 is inserted into the slide groove 7. A spring 8 is fixedly installed between the bottom of the slide groove 7 and the connecting rod 2 42. A positioning rod 9 is fixedly installed on the connecting rod 2 42, and the positioning rod 9 passes through the spring 8 and extends to the bottom of the spring 8.

[0039] When it is necessary to clamp and fix the four corners of the glass substrate 6, the second connecting rod 42 is pulled outward to fix the fixing device 5 at the four corners of the glass substrate 6. At this time, the spring 8 will apply an inward pulling force to the second connecting rod 42, thereby achieving a better clamping effect on the glass substrate 6; the setting of the positioning rod 9 can play a good guiding role, enhancing the rigidity of the connection between the second connecting rod 42 and the first connecting rod 41, and preventing the second connecting rod 42 from being separated from the first connecting rod 41, thereby affecting the clamping and fixing effect on the glass substrate 6.

[0040] Furthermore, the fixing device 5 is installed at the four corners of the glass substrate 6. The fixing device 5 includes a fixing block 51, a slot 52 and a tightening bolt 53. The fixing block 51 is fixedly connected to the second connecting rod 42. The front end of the fixing block 51 is provided with the slot 52. The slot 52 is adapted to be engaged with the right-angled edge of the glass substrate 6. The tightening bolt 53 passes through the groove wall at the top of the slot 52 to press the glass substrate 6.

[0041] The four right-angled sides of the glass substrate 6 are clamped with the corresponding clamping grooves 52, and then the tightening bolts 53 are used to further fix the glass substrate 6. The fixing effect is good, and the stability of the glass substrate 6 during the inspection process is enhanced.

[0042] Furthermore, the transverse cross-section of the locking groove 52 is an L-shaped structure, which fits in with the right-angled side of the glass substrate 6 , and can better fix the four corners of the glass substrate 6 , with a good fixing effect.

[0043] Furthermore, a handle 10 is vertically fixedly mounted on the outer end of the rotating rod 2 , and a limiting component 11 for limiting the position of the glass substrate 6 is mounted on the handle 10 .

[0044] When the glass substrate 6 needs to be flipped, the handle 10 is rotated. After the glass substrate 6 is flipped over, the position of the handle 10 is fixed using the limiting component 11, thereby completing the fixation of the position of the glass substrate 6. The operation method is simple and practical.

[0045] Furthermore, the limiting component 11 includes a limiting rod 111 and a limiting hole 112. The supporting frame 1 is provided with the limiting holes 112 directly above and directly below the rotating rod 2. The limiting rod 111 passes through the handle 10 and is inserted into the corresponding limiting hole 112.

[0046] When the handle 10 is rotated to the position of the corresponding limiting hole 112, the limiting rod 111 is inserted into the limiting hole 112 to perform a limiting operation, thereby quickly completing the limitation of the position of the glass substrate 6, so that the glass substrate 6 is always on a horizontal plane before and after flipping, which is convenient for detecting foreign objects on the glass substrate 6.

[0047] Furthermore, limit blocks 12 are fixedly mounted on the limit rods 111 on both sides of the handle 10 .

[0048] The setting of the limiting block 12 can prevent the limiting rod 111 from being separated from the handle 10, thereby affecting the smooth progress of the limiting work.

[0049] The working principle of this embodiment is as follows:

[0050] The second connecting rod 42 is pulled outward so that the slot 52 on the fixing block 51 at the end of the second connecting rod 42 is engaged with the right-angled edge of the glass substrate 6 , and then the tightening bolt 53 is rotated to further fix the glass substrate 6 .

[0051] After the laser scan of the glass substrate 1 on that side is complete, the limiting rod 111 is pulled outward, disengaging the limiting hole 112. The handle 10 is then rotated, driving the rotating rod 2 to rotate. The rotation of the rotating rod 2 drives the rotation of the connecting block 3, which in turn drives the rotation of the connecting rods 4 on both sides of the connecting block 3, ultimately completing the flipping of the glass substrate 6. After the glass substrate 6 is flipped, the limiting rod 111 is inserted into the corresponding limiting hole 112 to define the position.

[0052] The technical effect of the embodiment of the utility model is that the glass substrate foreign body detection device can quickly turn over the glass substrate without manually lifting the glass substrate again for the flipping operation. The operation method is simple, which greatly improves the efficiency of glass substrate flipping, saves labor costs, and ensures the smooth progress of glass substrate foreign body detection work.
