Description

Technical Field

[0001] The present invention relates to the technical field of screen strength detection, and in particular to a strength detection device for an electronic product screen. Background Art

[0002] In daily life, people use mobile phones very frequently, but mobile phone screens are fragile items and are very easy to fall and break during use. Therefore, the mobile phone screens need to be strength tested during the production process to ensure the production quality of the mobile phone screens. At present, when testing the compression resistance of the screen, a press is usually used to push the top pin to squeeze the screen surface, and the deformation and breakage of the screen are observed in order to estimate the maximum pressure that the screen can withstand.

[0003] The existing patent (publication number: CN112924282A) discloses a detection device based on air pressure adjustment of screen resistance, including a frame, the top of the frame is movably connected with a ratchet plate, the ratchet plate is elastically connected with ratchet 1 inside, the top of the frame is movably connected with a plug body 1 inside, the top of the plug body 1 is fixedly connected with a pressure block, and the left and right ends of the pressure block are fixedly connected with ratchet 2. The detection device based on air pressure adjustment of screen resistance, by pressing the pressure block, the plug body 1 changes the volume in the pressurized chamber, so that the air pressure in the pressurized chamber increases, as the cam rotates and cooperates with the connecting rod 1 to drive the plug body 2 to push up and increase the pressure of the plug body 3, the rack 1 moves and cooperates with the connecting rod 2 to drive the movable frame up and down, when the lifting tension roller is against the screen surface, the lifting block pushes the toggle block to connect the pressurized chamber with the internal air path of the lifting block, and at this time, the gas pressure presses down the ejector pin for detection. The prior art has the following problems: when the prior screen detection is used, pressure is applied to the screen by pushing the ejector pin down to the screen surface through a pressure mechanism. This method can only detect one point on the screen at a time. If other points on the screen need to be detected, the pressure mechanism needs to drive the ejector pin to move up, and then use a cross slide to translate the ejector pin to other points on the screen. Then the pressure mechanism pushes the ejector pin down again to contact the screen. The operation process has many steps and the detection efficiency is low. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 13 The present invention provides a technical solution: a strength detection device for an electronic product screen, comprising a base 1, a gantry 2 is fixedly connected to the edge of the top surface of the base 1, a protective component 3 is provided in the middle of the base 1, a detection component 4 is provided on the bottom surface of the top plate of the gantry 2, connecting components 5 are fixedly connected to both sides of the detection component 4, a clamping component 6 is hinged at the bottom of the connecting component 5, and a cleaning component 7 is provided in the middle of the detection component 4.

[0037] In this embodiment, Figure 1-7As shown, the detection component 4 includes a hydraulic rod 401 fixedly connected to the bottom surface of the top plate of the gantry 2, the output end of the hydraulic rod 401 is fixedly connected to the mounting plate 402, the bottom surface of the mounting plate 402 is fixedly connected to the vertical connecting rod 403, the bottom end of the vertical connecting rod 403 is welded with a fixing ring 404, the inner ring of the fixing ring 404 is integrally formed with a guide pin 405, the guide pin 405 extends to the inside of the spiral groove 406, the spiral groove 406 is arranged on the outside of the rotating column 407, the bottom surface of the rotating column 407 is fixedly connected to the cylinder 408, and the output end of the cylinder 408 is hinged An eccentric connecting rod 409 is provided, an eccentric ball 4010 is welded to the bottom end of the eccentric connecting rod 409, the eccentric ball 4010 is fixedly connected to the middle of the eccentric disk 4011, and the outer surfaces of the eccentric ball 4010 are respectively fitted with an upper limit ring 4012 and a lower limit ring 4013, the upper limit ring 4012 is fixedly connected to the top of a mounting frame 4014, the mounting frame 4014 is composed of a mounting ring and a mounting vertical rod, the mounting frame 4014 and the lower limit ring 4013 are both fixedly connected to the top surface of a fixed disk 4015, and a detection ejector pin 4016 is passed through the middle of the fixed disk 4015;There are two spiral grooves 406, and this structure can prevent the rotating column 407 from tilting under the reaction force when the cylinder 408 is extended. The eccentric ball 4010 is arranged between the upper limit ring 4012 and the lower limit ring 4013. The two limit rings can limit the eccentric ball 4010 to prevent the eccentric ball 4010 from escaping from between the two limit rings while allowing the eccentric ball 4010 to rotate. When it is necessary to perform strength testing on the electronic profile on the placement table 6010, the hydraulic rod 401 is extended and the rotating column 407 is pushed downward through the mounting plate 402. The rotating column 407 will drive the detection component 4 below to move downward synchronously until the bottom end of the detection ejector pin 4016 in the detection component 4 contacts the electronic profile. At this time, the pressure sensor will detect the pressure and transmit the data to the PLC controller. The PLC controller can be any one that can be purchased on the market. The PLC controller drives the cylinder 408 to extend. At the same time, the hydraulic rod 401 stops extending, and the cylinder 408 The extension changes the inclination angle of the eccentric disk 4011, thereby changing the length of the detection ejector pin 4016 being pressed down, so that the pressure between the detection ejector pin 4016 and the electronic screen changes. After that, the hydraulic rod 401 is started and extended again. At this time, the detection ejector pin 4016 has dropped to the lowest point and is blocked by the electronic screen. The hydraulic rod 401 pushes the fixed ring 404 to move downward, and the cooperation of the guide pin 405 and the spiral groove 406 on the inner ring of the fixed ring 404 is used to drive the rotating column 407 to rotate. The column 407 drives the eccentric disk 4011 to rotate eccentrically through the eccentric connecting rod 409, and squeezes down a number of detection ejector pins 4016 that penetrate the middle of the fixed disk 4015 in sequence. Since the spiral groove 406 rotates one circle, the eccentric disk 4011 also rotates one circle, ensuring that all the detection ejector pins 4016 are pressed down in sequence, realizing multi-point detection of the electronic screen, and this method does not need to lift the detection ejector pins 4016 to change the position of the ejector pins on the electronic screen, so the detection efficiency is improved. ;

[0038] In this embodiment, Figure 4 and Figure 6As shown, a limit plate 4016a is provided in the middle of the detection ejector pin 4016, and a spring 4016b is fixedly connected between the limit plate 4016a and the fixed disk 4015, and the top of the detection ejector pin 4016 is a spherical structure; a pressure sensor is provided at the bottom end of the detection ejector pin 4016, and the pressure sensor adopts the model DYHW-108. The pressure sensor can detect the pressure applied by the detection ejector pin 4016 to the electronic screen, and when the pressure sensor generates pressure as the detection ejector pin 4016 moves downward and contacts the top surface of the electronic screen, the data signal is sent to the PLC controller. The PLC controller is installed in the control box on the right side of the gantry 2. The PLC controller controls the cylinder 408 to extend or shorten to adjust the inclination angle of the eccentric disk 4011, and change the pressure applied by the detection ejector pin 4016 to the electronic screen to meet the different size types. The electronic screen strength test is performed by the eccentric disk 4011. When the eccentric disk 4011 rotates eccentrically, it will contact the spherical top of the detection ejector pin 4016 and squeeze the detection ejector pin 4016 downward, so that the bottom end of the detection ejector pin 4016 applies downward pressure to the electronic screen on the placement table 6010, so as to detect the electronic screen. When the high point of the eccentric disk 4011 contacts the detection ejector pin 4016, the spring 1 4016b will push the limit plate 4016a upward to reset the detection ejector pin 4016 upward. At this time, the bottom end of the detection ejector pin 4016 is separated from the electronic screen. It is worth noting that the fixed disk 4015 is fixedly connected to the lower connecting frame 505. When the fixed ring 404 drives the rotating column 407 to rotate, the height of the fixed disk 4015 remains unchanged, and the spring 1 4016b can be compressed, and then the subsequent rebound will reset the detection ejector pin 4016.

[0039] In this embodiment, Figure 2 and Figure 8-10As shown, the clamping assembly 6 includes a lifting block 601 hinged at the bottom of the connecting assembly 5, and a tilting connecting rod 602 is hinged in the middle of both sides of the lifting block 601. A mounting opening 603 is provided in the middle of the tilting connecting rod 602. A straight slot 604 is provided in the middle of one end of the tilting connecting rod 602 away from the lifting block 601. The middle of the straight slot 604 is penetrated by the connecting shaft in the middle of the hinge seat 605. A clamping claw 606 is rotatably connected between the inner walls of the mounting opening 603 through the connecting shaft. An arc groove 607 is provided in the middle of 606, and a fixing pin 608 runs through the middle of the arc groove 607. The fixing pin 608 is fixedly connected between the inner walls of the strip opening 609. The strip opening 609 is provided on both sides of the middle of the placing platform 6010. Four supporting columns 6011 are fixedly connected to the bottom surface of the placing platform 6010. The bottom ends of the four supporting columns 6011 are connected by a counterweight plate 6012. When the detection component 4 moves downward, it will drive the lifting block through the connecting component 5. When the lifting block 601 moves downward, the downward movement of the lifting block 601 will drive the tilting links 602 on both sides to move downward and move away from the lifting block 601, and the tilting links 602 will drive the clamping claws 606 to move synchronously. With the cooperation of the arc groove 607 and the fixing pin 608, the top of the clamping claw 606 will rotate toward the middle of the placement table 6010, and under the action of the tilting links 602, the clamping claw 606 will also move downward, so that the top of the clamping claw 606 will fix the electronic screen on the placement table 6010. This structure moves synchronously during the downward movement of the detection component 4, and automatically fixes the electronic screen to be inspected on the top surface of the placement table 6010. Conversely, when the detection is completed, when the detection component 4 moves upward, the hydraulic rod 401 will drive the lifting block 601 to move upward through the connecting component 5, so that the two clamping claws 606 automatically release the clamping fixation of the electronic screen, saving the time for fixing the electronic screen and further improving the detection speed of the electronic screen.

[0040] In this embodiment, Figure 8 As shown, the middle part of the placement table 6010 is hollowed out, and the hollowed-out part of the placement table 6010 is located directly below the detection ejector pin 4016, and the top surface of the hollow frame in the middle of the placement table 6010 is arc-shaped. This structure enables the detection ejector pin 4016 to perform strength detection on the electronic screen when it moves downward, and does not cause the detection ejector pin 4016 to be unable to press down due to the solid plate below the electronic screen, or the pressure sensor at the bottom of the detection ejector pin 4016 to detect inaccurate pressure due to the reaction force of the solid plate. The arc-shaped design of the top surface of the hollow frame can prevent glass fragments generated by the shattering of an unqualified electronic screen from remaining on the top surface of the hollow frame, causing squeezing or even shattering of the bottom surface of the next electronic screen to be inspected.

[0041] In this embodiment, Figure 1 , Figure 3 and Fig.13As shown, the protection assembly 3 includes two fixed side plates 301 fixedly connected to the top surface of the base 1 and two J-shaped rods 303 running through the middle of the base 1, the straight rod parts of the two J-shaped rods 303 are fixedly connected to the movable side plates 302, and the middle parts of the two J-shaped rods 303 are fixedly connected to the mounting plates 304, one side of the mounting plates 304 is provided with an arc spring 305, one end of the arc spring 305 away from the mounting plates 304 is connected to the bottom surface of the base 1, and the mounting plates 304 and the base 1 are connected by the arc spring 305. 05 constitutes an elastic structure, and the arc spring 305 is sleeved on the outer side of the bent rod part of the J-shaped rod 303, and the movable side plate 302 is composed of a horizontal plate and a vertical plate; when the clamping assembly 6 moves downward, the counterweight plate 6012 at the bottom thereof also moves downward, and when the counterweight plate 6012 contacts the bent rod part of the J-shaped rod 303, under the elastic force of the arc spring 305, the counterweight plate 6012 will stop moving downward, at this time, the lifting block 601 and the counterweight plate 6012 are relatively displaced, and the distance between the lifting block 601 and the counterweight plate 6012 The distance is shortened, and the tilting connecting rod 602 moves to both sides. When the straight slot 604 is close to the inner wall of one side of the lifting block 601 and contacts the connecting shaft in the middle of the hinge seat 605, the clamping claw 606 fixes the electronic screen on the top surface of the placement table 6010, and the lifting block 601 also drops to the lowest position. At this time, the lifting block 601 and the counterweight plate 6012 are relatively still, but the hydraulic rod 401 continues to extend, so the counterweight plate 6012 will squeeze the bent rod part of the J-shaped rod 303 downward, and the arc spring 305 will be stretched. The J-shaped rod 303 drives the movable side plate 302 to rotate with the center of the arc spring 305 as the midpoint until the horizontal plate parts of the two movable side plates 302 are parallel to the base 1. At this time, the outer ring of the fixed disk 4015 fits with the arc groove on the horizontal plate of the movable side plate 302, and cooperates with the two fixed side plates 301 to form a closed space, which will prevent the broken glass from splashing and injuring people during electronic profile detection. After the clamping assembly 6 clamps and fixes the electronic screen, the counterweight plate 6012 descends to drive the protective assembly 3 to close.

[0042] In this embodiment, Figure 2 , Figure 8 and Fig. 9 As shown, the connecting component 5 includes an upper connecting frame 501 welded to the outer ring of the fixing ring 404, the bottom end of the upper connecting frame 501 is fixedly connected with an inner rod 502, the inner rod 502 is slidably connected to the inside of the outer rod 503, a spring 2 504 is provided at the inner bottom of the outer rod 503, and the outer rod 503 is fixedly connected to the top of the lower connecting frame 505; the connecting component 5 is used to connect the detection component 4 and the clamping component 6, so that when the detection component 4 descends, it can simultaneously drive the lifting block 601 in the clamping component 6 to rise and fall, thereby driving the entire clamping component 6 to automatically fix the electronic screen to be inspected on the placement table 6010.

[0043] In this embodiment, Figure 2 , Figure 8 and Fig. 9 As shown, the upper connecting frame 501 and the lower connecting frame 505 are both "L"-shaped structures, and the bottom end of the inner rod 502 is connected to the top end of the second spring 504; when the two movable side plates 302 in the protective component 3 are closed, the bottom end of the lowest detection pin 4016 in the detection component 4 also contacts the top surface of the electronic screen to be inspected, and the strength of the contact point is tested. Then the hydraulic rod 401 continues to extend to make the eccentric disk 4011 rotate eccentrically, thereby driving all the detection pins 4016 to contact the electronic screen in turn for strength testing. During this process, in order to ensure that the clamping component 6 does not continue to apply pressure to the electronic screen and cause damage to the electronic screen, the two movable side plates 302 in the protective component 3 cannot continue to move closer, and the second spring 504 will be compressed by the inner rod 502, that is, the upper connecting frame 501 continues to move downward with the fixing ring 404, while the lower connecting frame 505 remains stationary.

[0044] In this embodiment, Figure 1 , Fig.11 and Fig.12 As shown, the cleaning component 7 includes a lifting ring 701 slidably connected to the middle part of the vertical rod of the mounting frame 4014, the outer ring of the lifting ring 701 is provided with a dust collecting chamber 702, the interior of the dust collecting chamber 702 is movably connected with a filter layer 703, the middle part of the outer ring of the dust collecting chamber 702 is connected with a vacuum fan 704, the bottom of the dust collecting chamber 702 is connected with the top of the dust suction pipe 705, and the bottom end of the dust suction pipe 705 is connected with a dust suction nozzle 706, a spring 707 is provided between the lifting ring 701 and the fixed plate 4015, and two lifting forks 708 are integrally formed on both sides of the lifting ring 701; when a detection ejector pin 4016 located at the bottom of the detection component 4 contacts the top surface of the screen to be tested, the dust suction nozzle 706 is not in contact with the placement table 601 at this time 0 top surface, then, as the hydraulic rod 401 continues to extend, it will drive the eccentric disk 4011 to rotate so that each detection ejector pin 4016 will perform strength detection on multiple points on the screen to be tested in turn. During this process, the upper connecting frame 501 will descend and contact the top surface of the lifting fork 708, pressing the lifting fork 708 downward. The descent of the lifting fork 708 will drive the dust suction nozzle 706 to descend through the lifting ring 701, the dust collecting chamber 702 and the dust suction pipe 705. When the last detection ejector pin 4016 contacts the electronic screen, the dust suction nozzle 706 just contacts the top surface of the placement table 6010. At this time, the vacuum fan 704 can be started to suck the glass fragments on the placement table 6010 into the dust collecting chamber 702, thereby completing the cleaning of the placement table 6010.

[0045] In this embodiment, Fig.11 and Fig.12As shown, two lifting forks 708 are located directly below the upper connecting frame 501, there are four dust suction nozzles 706, and the four dust suction nozzles 706 are divided into two groups, and the coverage area of ​​the two groups of dust suction nozzles 706 is the outer area of ​​the hollow part in the middle of the placement table 6010, and the two groups of dust suction nozzles 706 are symmetrically distributed about the clamping claw 606, and the dust suction nozzles 706 do not contact the clamping claw 606, and the bottom surface height of the dust suction nozzles 706 is higher than the bottom end height of the detection ejector pin 4016; the dust suction pipe 705 runs through the edge of the fixed plate 4015 and is slidably connected to the fixed plate 4015, and the outer ring of the dust collecting chamber 702 is provided at both ends. The two doors can be opened to clean the impurities accumulated inside the dust collecting chamber 702, and the filter layer 703 in the dust collecting chamber 702 can also be replaced. The four dust nozzles 706 cover the area outside the hollow part of the placement table 6010 in order to absorb the glass fragments remaining on the placement table 6010 and suck the fragments into the dust collecting chamber 702 to achieve automatic cleaning of the glass placement table 6010. Because the top surface of the hollow part in the middle of the placement table 6010 is an upwardly protruding arc design, the debris will naturally slide down. Therefore, the dust nozzle 706 does not need to cover the hollow part of the placement table 6010.

[0046] The use method and advantages of the present invention: When the strength detection device of the electronic product screen is used, the working process is as follows:

[0047] First, place the electronic screen to be tested on the placement table 6010, then start the hydraulic rod 401 to push the detection component 4 downward. During the downward movement of the detection component 4, the connecting component 5 will be driven to move downward synchronously through the fixing ring 404, and the downward movement of the connecting component 5 will drive the clamping component 6 to descend. When the counterweight plate 6012 in the clamping component 6 contacts the J-shaped rod 303 in the protection component 3, the height of the clamping component 6 will not continue to decrease temporarily, but the lifting block 601 in the clamping component 6 begins to descend, so that the clamping claw 606 fixes the electronic screen. During the descent of the lifting block 601, the detection ejector pin 4016 continues to move downward until The detection ejector pin 4016 comes into contact with the electronic profile, and the clamping jaw 606 also fixes the electronic screen at this time. When the detection ejector pin 4016 comes into contact with the electronic screen, the pressure sensor transmits data to the PLC controller, and the PLC controller starts the cylinder 408 to extend, and changes the angle of the eccentric disk 4011, so as to squeeze the lowest detection ejector pin 4016 downward to apply downward pressure to the electronic screen, and complete the strength detection of a point on the electronic screen. Since the elastic force of the spring 2 504 is equal to the downward pressure required by the guide pin 405 to drive the rotating column 407, which is greater than the elastic force of the arc spring 305, the clamping jaw 606 is fixed to the electronic screen. After the fixation is completed, the clamping assembly 6 moves downward as a whole and presses the J-shaped rod 303 downward, driving the two movable side plates 302 in the protective assembly 3 to move closer to the fixed disk 4015, until the movable side plates 302 fit the fixed disk 4015, and the electronic screen is enclosed in the interior of the protective assembly 3 to prevent the glass fragments generated by the electronic screen breaking during the detection from splashing and injuring people. After that, the hydraulic rod 401 continues to push the fixed ring 404 downward, and the guide pin 405 on the inner ring of the fixed ring 404 drives the rotating column 407 to rotate, thereby rotating the eccentric disk 4011, and sequentially squeezing the detection ejector pin 4016 to perform strength detection on multiple points on the electronic screen, and in the fixed ring When the rotating column 407 is rotated by moving downward, the fixing ring 404 will also squeeze the lifting fork 708 in the cleaning assembly 7 downward through the upper connecting frame 501. When the rotating column 407 rotates one circle, all the detection pins 4016 have completed the strength test. At this time, the dust suction nozzle 706 contacts the top surface of the placement table 6010 under the downward pressure of the lifting fork 708, and then the vacuum fan 704 is started to suck the glass fragments on the placement table 6010 into the dust collecting chamber 702 for collection, thereby completing the automatic cleaning of the placement table 6010 and preventing the remaining glass fragments on the placement table 6010 from squeezing and damaging the next electronic screen to be tested.
