Description

Technical Field

[0001] The utility model relates to the technical field of glass detection auxiliary equipment, in particular to a display screen carrier glass sampling inspection device. Background Art

[0002] Carrier glass is a thin glass sheet with a very flat surface. It is an upstream key material for the manufacture of OLED high-definition display panels. It is used in the production of flexible OLED panels and plays a bearing role in the panel manufacturing process. OLED high-definition display is more complex than other display industries, and has higher requirements for the quality of carrier glass.

[0003] Existing carrier glass is generally mass-produced in a production line. In order to ensure that each batch of carriers meets factory requirements, random inspection is required.

[0004] In the prior art, there is a patent document with a patent publication number of CN219161967U and a patent name of "A rapid detection device for carrier glass for display screens". In this patent, a detection platform and a detection camera are set on a support frame to quickly detect whether there are cracks in the carrier glass. In actual use, in order to ensure the accuracy of the detection, a certain number of samples to be tested are generally continuously drawn on the same production line, and then the drawn samples are moved to professional testing equipment for testing. However, this equipment can only detect one sample at a time and cannot ensure the accuracy of the detection. Some carrier glass is very thin and generally transparent, making it difficult to count with the naked eye. Therefore, when batch sampling is performed, it is easy to have too many or too few samples. Utility Model Content

[0005] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a display screen carrier glass sampling device, which sets a pressure sensor under the storage box to achieve the control of the number of samples to be tested without counting, making it easier to simplify the operation and improving the purpose of equipment automation.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a display screen carrier glass sampling device, comprising a bracket and a storage box; a connecting plate is fixedly provided on one side of the storage box, and a guide wheel for clamping the bracket is provided on the connecting plate, and a storage cavity is provided in the storage box; a limit block is also provided on the bracket, and a pressure push rod and a pressure sensor are provided on the top of the limit block, the pressure push rod is sleeved in a sleeve, and a pressure spring that always abuts against the pressure push rod is also provided in the sleeve, and the pressure sensor is electrically connected to an alarm device, and when the connecting plate contacts the pressure sensor, the alarm device is energized and an alarm is sounded.

[0007] Preferably, the bracket and the connecting plate are both provided with matching fixing pin holes, and limiting pins for fixing the connecting plate are inserted into the fixing pin holes.

[0008] Preferably, a carrying plate is provided in the storage cavity, and a plurality of the carrying plates are cross-placed in the storage cavity, and hoisting transfer holes for hoisting the carrying plates are provided in the middle of two of the carrying plates.

[0009] Preferably, one end of the storage cavity is open, and a pushing mechanism is provided away from the open end. The pushing mechanism comprises a pushing plate, and a telescopic cylinder is connected to the rear end of the pushing plate.

[0010] Preferably, two pressure push rods are respectively provided on both sides of each pressure sensor.

[0011] Preferably, the side wall of the sleeve is also provided with a plurality of adjustment holes for adjusting the elastic force of the pressure spring.

[0012] After adopting the above technical solution, the beneficial technical effects achieved by the utility model are:

[0013] 1. Due to the provision of a bracket and a storage box, a connecting plate is fixedly provided on one side of the storage box, a guide wheel for clamping the bracket is provided on the connecting plate, and a storage cavity is provided in the storage box, so that the storage box can move up and down. A limit block is also provided on the bracket, and a pressure push rod and a pressure sensor are provided on the top of the limit block. The pressure push rod is sleeved in a sleeve, and a pressure spring that always abuts against the pressure push rod is also provided in the sleeve. The pressure sensor is electrically connected to an alarm device. When the connecting plate contacts the pressure sensor, the alarm device is powered on and an alarm is sounded. When a certain number of glass samples to be tested are placed on the storage box, the storage box will exert a certain pressure on the pressure push rod downward, forcing the pressure push rod to move downward. When the connecting plate contacts the pressure sensor, the alarm is powered on and an alarm is sounded. The quality of each piece of glass to be tested is certain. When a certain number of glasses to be tested are placed on the storage box, the pressure generated is also fixed. In this way, there is no need to determine the number of glasses to be tested to ensure the accuracy of the number of tests.

[0014] 2. Since one side of the storage cavity is open and a push plate is provided on the side away from the opening, after weighing, the push plate can be used to directly push the carrier plate and the carrier glass to be tested above it onto the feeding trolley, avoiding manual handling and scratches. In addition to the push mechanism, the carrier plate of the utility model is also provided with a hoisting transfer hole, and the carrier glass with a volume smaller than the carrier plate can also be transported by hoisting.

[0015] 3. Since a plurality of adjustment holes for adjusting the elastic force of the pressure spring are provided on the side wall of the sleeve, the volume length of the compression spring in the sleeve can be adjusted through the adjustment holes, thereby changing its top force on the storage box, and it is easy to be applied to a variety of different types of carrier glass.

[0023] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] See also Figure 1-Figure 2The utility model provides a device for sampling inspection of display screen carrier glass, characterized in that it includes a bracket 1 and a storage box 2; a connecting plate 21 is fixedly provided on one side of the storage box 2, a guide wheel 22 for clamping the bracket 1 is provided on the connecting plate 21, and a storage cavity is provided in the storage box 2; a limit block 5 is also provided on the bracket 1, a pressure push rod 51 and a pressure sensor 52 are provided on the top of the limit block 5, the pressure push rod 51 is sleeved in a sleeve 53, and a pressure spring that always abuts against the pressure push rod 51 is also provided in the sleeve 53, and the pressure sensor 52 is electrically connected to an alarm device, and when the connecting plate 21 contacts the pressure sensor 52, the alarm device is powered on and an alarm is sounded. Affected by the processing technology and materials, it is impossible for any product to achieve a 100% qualified rate, so it is necessary to sample the product at regular intervals. There are also certain requirements for the number of samples sent for inspection of carrier glass, which is generally an integer, 5 or 10 pieces in most cases, and can be sampled continuously or randomly. First, remove the fixing pin in the fixing pin hole 211 so that the storage box 2 can slide up and down. Under the action of gravity, the storage box 2 will naturally fall and contact the pressure push rod 51. At this time, the pressure push rod 51 will be compressed to a certain extent, but it will not trigger an alarm. When a certain number of samples to be tested are placed on the storage box 2, the pressure increases. When the pressure reaches the preset value, the connecting plate 21 will contact the pressure sensor 52 and sound an alarm. If the specifications of the samples to be tested are the same, the number of samples to be tested on the storage box 2 is certain, and there is no need to count them manually, so the consistency of the number of samples sent for inspection each time can be guaranteed.

[0025] The bracket 1 and the connecting plate 21 of the utility model are both provided with matching fixing pin holes 211, and the fixing pin holes 211 are inserted with limit pins for fixing the connecting plate 21. When it is not necessary to detect the number of placements, the position of the storage box 2 is fixed by the limit pin to ensure that it exerts pressure on the pressure push rod 51. At this time, the storage box 2 is used as a temporary storage platform.

[0026] The storage cavity of the utility model is provided with a carrying plate 3, and a plurality of carrying plates 3 are cross-placed in the storage cavity, and two of the carrying plates 3 are provided with hoisting and transportation holes 31 in the middle for hoisting the carrying plates 3. For some samples with larger volumes to be tested, when the pusher plate 41 is used to move, it is easy to directly contact the samples to be tested. At this time, a crane or forklift is used to ensure that there is no interference with the samples to be tested during hoisting and transportation.

[0027] The storage cavity of the utility model is open at one end, and a pushing mechanism 4 is provided away from the open end, and the pushing mechanism 4 includes a pushing plate 41, and a telescopic cylinder 42 is connected to the rear end of the pushing plate 41. The telescopic cylinder 42 is generally a pneumatic cylinder or an electric cylinder, and the pushing plate 41 directly pushes the carrying plate 3 out of the storage box 2. Generally, a mobile trolley or other carrying equipment is placed on the opening side of the storage box 2.

[0028] Two pressure push rods 51 are respectively arranged on both sides of each pressure sensor 52 of the utility model. The two pressure push rods 51 are generally symmetrically installed on the left and right sides of the pressure sensor 52. The two pressure push rods 51 on each side jointly form a support, which makes the support effect of the storage box 2 more stable and not easy to tilt.

[0029] The side wall of the sleeve 53 of the utility model is also provided with a plurality of adjustment holes for adjusting the elastic force of the pressure spring. The adjustment holes are used to adjust the elastic force of the pressure spring to ensure that the alarm device can be triggered after a preset number of samples to be tested are placed on the storage box 2. Generally, a ball buckle is used to limit the position in the adjustment hole. This technology is a prior art and is widely used in umbrella frames. In addition to using the above-mentioned technical features, bolts can also be used to adjust the elastic force of the spring. Bolts to adjust the elastic force of the spring are a prior art and are widely used in vehicle shock absorption systems. The main purpose is to ensure that the pressure reaches a predetermined value and can trigger an alarm.

[0030] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
