Description

Technical Field

[0001] This utility model belongs to the field of glass screen printing, specifically, it relates to a pre-screening positioning and perforation detection structure. Background Technology

[0002] Before the glass enters the screen printing process, it needs to be drilled with laser drilling equipment to meet the requirements of subsequent processing, assembly and function. However, due to process fluctuations, some holes on the glass may not be completely drilled. Incompletely drilled holes are prone to puncturing the screen during the coating process, affecting the integrity and style of the screen printing pattern, speeding up the screen replacement frequency, increasing production costs and affecting glass processing efficiency.

[0003] To address the aforementioned issues, patent application number 2016205946781 discloses an automatic glass screen printing machine, comprising a base plate and a DDC controller. A first cylinder is mounted on the upper end of the base plate, and a mounting plate is mounted on the upper end of the telescopic shaft of the first cylinder. An operating table is mounted above the mounting plate via a support column. A second cylinder is mounted on the upper middle part of the mounting plate, and a top plate is mounted on the upper end of the telescopic shaft of the second cylinder. A top rod is provided on the upper end of the top plate. A hole for the top rod to pass through is opened in the base of the operating table. A screen is mounted above the operating table via a bracket. A third cylinder is mounted on the upper right side of the screen, and a scraper is mounted on the left end of the telescopic shaft of the third cylinder. The first, second, and third cylinders are all electrically connected to the DDC controller, but this design fails to solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a pre-screening positioning perforation detection structure is provided that can effectively prevent glass with incompletely perforated holes from flowing into the screen printing machine, reduce the risk of screen breakage, reduce the frequency of screen replacement, and help reduce production and labor costs.

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0027] Figure 1 This is a schematic diagram of the connection of the photoelectric sensor module in an embodiment of this utility model.

[0028] like Figure 1 As shown, the pre-screening positioning and perforation detection structure provided by this utility model includes a positioning bracket and a photoelectric sensor module 10 mounted on the positioning bracket. The positioning bracket includes a mounting base 20 and a bracket body 30 mounted on the mounting base 20. The mounting base 20 is mounted on the gantry crane beam. One end of the bracket body 30 is connected to the mounting base 20, and the other end of the bracket body 30 is connected to the photoelectric sensor module 10. The photoelectric sensor module 10 is aligned with the drilled hole on the glass through the positioning bracket, which facilitates the photoelectric sensor module to identify whether the hole is completely drilled. This effectively prevents glass with incompletely drilled holes from flowing into the screen printing machine, reduces the risk of screen breakage, reduces the frequency of screen replacement, and helps to reduce production and labor costs.

[0029] like Figure 1 As shown, the photoelectric sensor module 10 includes a photoelectric transmitter 11, a screen printing machine PLC assembly 12, a screen printing machine conveyor belt switch 13, and an alarm 14. The output terminal of the photoelectric transmitter 11 is connected to the screen printing machine PLC assembly 12 through a signal processing circuit. The screen printing machine conveyor belt switch 13 is connected to the screen printing machine PLC assembly 12. The alarm 14 is connected to the screen printing machine PLC assembly 12. The photoelectric receiver used in conjunction with the photoelectric transmitter 11 is located below the glass drilling hole and is connected to the screen printing machine PLC assembly 12.

[0030] The photoelectric transmitter 11 emits a detection parallel light. When the hole is completely drilled, the detection parallel light passes smoothly through the hole and reaches the photoelectric receiver, indicating that the hole is completely drilled. When the hole is not completely drilled, the detection parallel light is affected by the glass and deflected or blocked, so the photoelectric receiver cannot receive the detection parallel light, indicating that the hole is not completely drilled. At this time, the screen printing machine PLC assembly 12 receives the signals from the photoelectric transmitter 11 and the photoelectric receiver, closes the screen printing machine conveyor belt switch 13, stops the operation of the screen printing machine conveyor belt, and stops the glass conveying. This effectively prevents glass with incompletely drilled holes from flowing into the screen printing machine, reduces the risk of screen breakage, reduces the frequency of screen replacement, and helps to reduce production and labor costs. At the same time, the screen printing machine PLC assembly 12 controls the alarm 14 to work, reminding on-site personnel that the hole on the glass is not completely drilled.

[0031] Figure 2 This is a schematic diagram of the mounting base in an embodiment of this utility model.

[0032] like Figure 2 As shown, the mounting base 20 includes a mounting base plate 21 and mounting protrusions 22 disposed on the mounting base plate 21. The mounting base plate 21 has first mounting holes 211, which are evenly distributed on the mounting base plate 21. Screws are inserted through the first mounting holes 211 and into the gantry crane beam, thereby stably mounting the mounting base 20 onto the gantry crane beam and improving the stability of the photoelectric sensor module 10 during the detection process. The mounting protrusions 22 have second mounting holes 221, which are used to connect with the bracket body 30.

[0034] like Figure 3 , Figure 4 as well as Figure 5 As shown, the bracket body 30 includes a first support plate 31, and a first side plate 32 is connected to the first support plate 31. The first side plate 32 is connected to one side of the first support plate 31, so that the first support plate 31 and the first side plate 32 form an "L" shape. The first support plate 31 is provided with a first waist-shaped hole 311. Two first waist-shaped holes 311 are aligned with each other on the first support plate 31. The first side plate 32 is provided with a positioning hole 321. The positioning hole 321 is used to install and arrange the photoelectric transmitter 11. The photoelectric transmitter 11 is installed in the positioning hole 321 and is located above the glass drilling hole position, which facilitates the detection of the status of the glass drilling hole position.

The second side plate 34 is connected to one side of the second support plate 33, making the second support plate 33 and the second side plate 34 form an "L" shape. The second support plate 33 is provided with a second waist-shaped hole 331 and a wire hole 332. The two second waist-shaped holes 331 are aligned with each other on the second support plate 33. The second waist-shaped holes 331 correspond to the first waist-shaped holes 311. The first support plate 31 and the second support plate 33 are connected by bolts passing through the first waist-shaped holes 311 and the second waist-shaped holes 331. The positional relationship between the first support plate 31 and the second support plate 33 can be easily adjusted, and the position height of the photoelectric transmitter 11 can be easily adjusted along the direction of the first support plate 31, which improves the reliability of the structure. The wire hole 332 facilitates the arrangement of the signal processing circuit of the photoelectric transmitter 11. The second side plate 34 is provided with a third waist-shaped hole 341, and the two third waist-shaped holes 341 are aligned with each other on the second side plate 34.

[0038] like Figure 9 , Figure 10 as well as Figure 11 As shown, the bracket body 30 also includes a first connecting arm 35 and a second connecting arm 36. One end of the first connecting arm 35 is provided with a first connecting hole 351. The two first connecting holes 351 are located at the ends of the first connecting arm 35 and are adapted to the third oblong hole 341. Bolts are inserted through the first connecting holes 351 and the third oblong hole 341 to connect the first connecting arm 35 to the second side plate 34 and the second support plate 33.
