Description

Technical Field

[0001] The invention belongs to the technical field of electronic equipment detection, in particular to an electronic equipment detection device. Background Art

[0002] Electronic equipment is electronic products, which are related products that use electricity as the basis for their work, mainly including: watches, mobile phones, televisions, DVD players, video recorders, camcorders, radios, radio recorders, combination speakers, laser players, computers, game consoles, mobile communication products, etc.

[0003] Currently, mobile phones need to undergo a variety of tests before leaving the factory, among which the micro-drop test is one of the many tests. The micro-drop test is used to simulate the scene where a person places a mobile phone on a table.

[0004] The existing mobile phone micro-drop test machine mainly uses a suction cup that moves up and down to suck the mobile phone. When the mobile phone reaches a specified height, air is blown on the suction cup, and the mobile phone falls from the suction cup. The dropped mobile phone falls on the test bench, and then the suction cup is controlled to move down to suck the mobile phone again, and then released again, thereby realizing a cyclic micro-drop test of the mobile phone;

[0005] However, in order to better suck the mobile phone, the test bench will use evenly arranged baffles to block the mobile phone, thereby limiting the position where the mobile phone falls. At the same time, the fallen mobile phone will also hit the baffle. At the same time, because the suction cup is always facing downward, the mobile phone can only fall to the same position, resulting in the existing mobile phone micro-drop test machine being unable to simulate the scene where the mobile phone is actually placed on the table. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art and solve the above technical problems, the present invention proposes an electronic device detection device, which uses a cylinder to control the drop table to present different tilt states, so that when testing a mobile phone, a micro drop test can be performed on the mobile phone in different tilt states, so that when testing the mobile phone, it is more in line with the real simulation of the scene of the mobile phone being placed on the table. The specific structural design of the present invention is as follows:

[0007] An electronic equipment detection device includes a micro drop tester; the micro drop tester includes a test bench; a test mechanism is installed above the test bench;

[0008] The testing mechanism comprises a drop table; support plates are fixedly installed at the four corners of the drop table; cylinders are installed at the four corners of the testing table, and the elongated axes of the cylinders are spherically connected with the adjacent support plates;

[0009] A mounting tube is fixedly installed in the middle of the drop platform; a conduit is installed in the mounting tube, and the conduit is connected to an external air source through an air pipe;

[0010] A first suction cup is installed below the installation cylinder, and the first suction cup is connected to the conduit; the first suction cup is used to absorb the mobile phone to be tested;

[0011] The two sides of the installation tube are provided with cylindrical grooves in the drop platform; the opposite side of the cylindrical groove is provided with a column fixedly installed on the top of the drop platform;

[0012] A mounting plate is fixedly mounted on the top of the two columns; an electric telescopic rod is fixedly mounted on the top of the mounting plate; the extension axis of the electric telescopic rod extends to the bottom of the mounting plate;

[0013] The extension axis of the electric telescopic rod extends to one side below the mounting plate and is fixedly mounted with a mounting block; both side end surfaces of the mounting block facing the column are fixedly mounted with pull ropes;

[0014] The other ends of the pull ropes pass through the cylindrical grooves and extend to the bottom of the drop platform; the ends of the two pull ropes extending to the bottom of the drop platform are both fixedly connected to second suction cups. When testing the mobile phone, the mobile phone needs to be adsorbed on the two second suction cups first;

[0015] The lengths of the two pull ropes are greater than the distance from the first suction cup to the test bench.

[0016] Preferably, the two cylindrical grooves are both slidably connected with a wire barrel, and the wire barrel partly extends to below the drop platform; the pull rope passes through the wire barrel;

[0017] Support rings are fixedly installed on the outer ring surfaces of the two wire barrels; a spring is fixedly connected to the upper surface of the support ring, and the other end of the spring is fixedly connected to the lower surface of the drop platform;

[0018] Preferably, three evenly arranged extension rods are fixedly connected to the surface of the wire tube on one side of the wire tube facing the first suction cup; and the bottom ends of the extension rods are arc-shaped.

[0019] Preferably, the outer ring surface of the column is a smooth surface; a slip ring is slidably connected to the column, and the slip ring itself has a certain weight;

[0020] The pull rope passes through the slip ring; the side of the pull rope passing through the slip ring is fixedly connected inside the slip ring;

[0021] Preferably, the pull rope is fixedly connected with evenly arranged counterweight blocks;

[0022] Preferably, the counterweight is a round ball, and the surface of the round ball is smooth;

[0023] Preferably, a guide bin is fixedly connected to the top of the drop platform above the cylindrical groove; the side of the guide bin facing the column is of open design;

[0024] Preferably, a semicircular notch is formed on a side of the wire tube away from the first suction cup; and the semicircular notch is located below the support ring.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The electronic device detection device described in the present invention uses a cylinder to control the drop table to present different tilt states. When testing the mobile phone, a micro-drop test can be performed on the mobile phone in different tilt states, so that when testing the mobile phone, it is more in line with the real simulation of the scene of the mobile phone being placed on the table. At the same time, the mobile phone is sucked by two second suction cups, the suction cups are fixed by a pull rope, and the baffle that blocks the mobile phone in the prior art is abandoned. It can prevent the mobile phone from hitting the baffle when it falls at an angle, thereby affecting the normal falling trajectory of the mobile phone. At the same time, it can prevent the mobile phone from sliding when testing in different tilt states. When the mobile phone slides, the pull rope can be used to pull the mobile phone, so that there is no need to manually adsorb the mobile phone on the first suction cup.

[0027] 2. The electronic device detection device described in the present invention has a semicircular groove on the side of the wire tube away from the first suction cup. Therefore, part of the pull rope that falls into the wire tube will slide out of the semicircular groove and extend to the outside under the gravity of the counterweight. Then, when the first suction cup releases the mobile phone for testing, the mobile phone will fall downward under its own gravity. Since part of the pull rope extends to the outside through the semicircular groove, the pull rope will also fall downward and gradually unfold under the gravity of the counterweight during the falling process of the mobile phone. Therefore, during the falling process of the mobile phone, it can be avoided that the pull rope needs to be pulled downward when the mobile phone falls, which will affect the falling speed of the mobile phone and make it impossible to truly simulate the scene of the mobile phone being placed on the table.

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] Embodiment 1:

[0043] like Figures 1 to 10 As shown, an electronic equipment detection device according to the present invention comprises a micro drop test machine; the micro drop test machine comprises a test bench 1; a test mechanism is installed above the test bench 1;

[0044] The test mechanism comprises a drop table 2; support plates 21 are fixedly installed at the four corners of the drop table 2; cylinders 11 are installed at the four corners of the test table 1, and the elongated axes of the cylinders 11 are spherically connected to the adjacent support plates 21;

[0045] A mounting tube 22 is fixedly installed in the middle of the drop platform 2; a conduit 23 is installed in the mounting tube 22, and the conduit 23 is connected to an external air source through an air pipe;

[0046] A first suction cup 24 is installed below the installation tube 22, and the first suction cup 24 is connected to the conduit 23; the first suction cup 24 is used to absorb the mobile phone to be tested;

[0047] The two sides of the installation tube 22 are provided with cylindrical grooves 3 in the drop platform 2; the opposite side of the cylindrical groove 3 is provided with a column 25 fixedly installed on the top of the drop platform 2;

[0048] A mounting plate 4 is fixedly mounted on the top of the two uprights 25; an electric telescopic rod 41 is fixedly mounted on the top of the mounting plate 4; the elongated axis of the electric telescopic rod 41 extends to the bottom of the mounting plate 4;

[0049] The extension axis of the electric telescopic rod 41 extends to one side below the mounting plate 4 and is fixedly mounted with a mounting block 42; both side end surfaces of the mounting block 42 facing the column 25 are fixedly mounted with pull ropes 43;

[0050] The other ends of the pull ropes 43 pass through the cylindrical grooves 3 and extend to the bottom of the drop platform 2; the ends of the two pull ropes 43 extending to the bottom of the drop platform 2 are both fixedly connected to the second suction cups 44. When testing the mobile phone, the mobile phone needs to be adsorbed on the two second suction cups 44 first;

[0051] The length of the two pull ropes 43 is greater than the distance from the first suction cup 24 to the test bench 1;

[0052] Specifically, before performing a micro drop test on a mobile phone, the staff first adsorbs the two second suction cups 44 on the mobile phone, and at the same time, it is necessary to reserve an area between the two second suction cups 44 for the first suction cup 24 to adsorb, and then start the micro drop test machine. When the micro drop test machine is started, the electric telescopic rod 41 will be controlled to shrink. When the electric telescopic rod 41 shrinks, it will drive the mounting block 42 to gradually move upward. In the process of the mounting block 42 moving upward, the two pull ropes 43 on both sides of the mounting block 42 will be driven to gradually move upward. In the process of the pull rope 43 moving upward, the pull rope 43 gradually passes through the cylindrical groove 3. At the same time, the pull rope 43 will pull the two second suction cups 44 to gradually move upward, and the two second suction cups 44 will drive the mobile phone to move upward, and the mobile phone that moves upward will gradually approach the first suction cup 24. When the mobile phone is in contact with the first suction cup 24, the electric telescopic rod 41 drives the mounting block 42 to move upward to the limit position. At this time, the pull rope 43 is also in a tightened state. Then, the trachea is used to evacuate the conduit 23, so that the gas inside the first suction cup 24 can be extracted. When the gas in the first suction cup 24 is extracted, the mobile phone will be adsorbed on the first suction cup 24, and then a micro drop test can be performed;

[0053] More specifically, when performing a micro drop test, the electric telescopic rod 41 is first controlled to extend to the limit position, thereby driving the mounting block 42 and the pull rope 43 to move downward. When the pull rope 43 is connected to the mounting block 42 and moves downward together, the pull rope 43 is in a relaxed state. Then, the trachea is controlled to blow air into the conduit 23, and the gas enters the first suction cup 24. When the gas enters the first suction cup 24, the first suction cup 24 no longer adsorbs the mobile phone, so the mobile phone will fall downward onto the test bench 1, thereby simulating a scene where the mobile phone is placed on a table. Then, the electric telescopic rod 41 is controlled to extend and retract again, and the pull rope 43 is pulled upward. At the same time, the pull rope 43 pulls the second suction cup 44 and the mobile phone upward, so that the mobile phone is adsorbed on the first suction cup 24 again, and then the micro drop test can be performed again.

[0054] Furthermore, in order to more realistically simulate the scene of placing a mobile phone on the table, the staff can arbitrarily control the two cylinders 11 on one side to extend a certain distance. After the two cylinders 11 on one side are extended, the mounting plate 4 ball-connected with the cylinder 11 will be driven to move up. Since the cylinder 11 is ball-connected with the mounting plate 4, the drop platform 2 can be tilted as a whole. When the drop platform 2 is tilted, the mobile phone adsorbed on the first suction cup 24 is also tilted, and then the mobile phone can be subjected to a micro-drop test. Since the four mounting plates 4 on the drop platform 2 are ball-connected with the cylinders 11, when the two cylinders 11 on the left side of the drop platform 2 are controlled to extend, the drop platform 2 is in an inclined state with the left side higher and the right side lower. When the two cylinders 11 on the right side of the drop platform 2 are extended, the drop platform 2 is in an inclined state with the right side higher and the left side lower. When the two cylinders 11 on the rear side of the drop platform 2 are extended, the drop platform 2 is in an inclined state with the rear side higher and the front side lower. When the two cylinders 11 on the front side of the drop platform 2 are extended, the drop platform 2 is in an inclined state with the front side higher and the back side lower. Therefore, when the two cylinders 11 on different sides are extended, the inclination direction of the drop platform 2 can be changed. Therefore, the mobile phone can be subjected to a micro-drop test in different inclination states. Compared with the existing method that can only simulate the scene of the mobile phone being placed on the table in one way, the micro-drop test machine can more realistically simulate the scene of the mobile phone being placed on the table in different states.

[0055] Therefore, by using the cylinder 11 to control the drop table 2 to present different tilt states, the mobile phone can be subjected to a micro-drop test in different tilt states during the mobile phone test, so that when testing the mobile phone, it is more in line with the real simulation of the scene of the mobile phone being placed on the table. At the same time, by using two second suction cups 44 to suck the mobile phone, using the pull rope 43 to fix the suction cups, and abandoning the baffle that blocks the mobile phone in the prior art, the mobile phone can be prevented from hitting the baffle when it falls at an angle, thereby affecting the normal falling trajectory of the mobile phone. At the same time, the mobile phone can be prevented from sliding when tested in different tilt states. When the mobile phone slides, the pull rope 43 can be used to pull the mobile phone, so that the mobile phone does not need to be manually adsorbed on the first suction cup 24.

[0056] Embodiment 2:

[0057] The two cylindrical grooves 3 are both slidably connected with a wire barrel 31, and the wire barrel 31 partially extends to the bottom of the drop platform 2; the pull rope 43 passes through the wire barrel 31;

[0058] A support ring 32 is fixedly installed on the outer ring surface of the two wire tubes 31; a spring is fixedly connected to the upper surface of the support ring 32, and the other end of the spring is fixedly connected to the lower surface of the drop platform 2;

[0059] In this embodiment, three evenly arranged extension rods 33 are fixedly connected to the surface of the wire tube 31 on one side of the wire tube 31 facing the first suction cup 24; the bottom end of the extension rod 33 is arc-shaped;

[0060] Specifically, when the pull cord 43 pulls the second suction cup 44 and the mobile phone to move upward, the pull cord 43 connected to the second suction cup 44 will gradually approach the wire barrel 31. When the distance between the second suction cup 44 and the wire barrel 31 gradually approaches, the wire barrel 31 can restrict the pull cord 43, thereby reducing the shaking amplitude of the second suction cup 44 and the mobile phone, and preventing the mobile phone from shaking too much and failing to be attached to the first suction cup 24.

[0061] More specifically, when the mobile phone gradually approaches the wire barrel 31, the extension rod 33 fixed to the wire barrel 31 will first contact the mobile phone. When the extension rod 33 contacts the mobile phone, it can rest on the mobile phone, thereby limiting the position of the mobile phone and preventing it from shaking. As the second suction cup 44 gradually moves upward, the mobile phone will push the extension rod 33 upward, and at the same time, the extension rod 33 will drive the wire barrel 31 to slide upward in the cylindrical groove 3, and the support ring 32 will squeeze the spring. Then the mobile phone will fit with the first suction cup 24 and be adsorbed on the first suction cup 24. In this process, the mobile phone is limited by the wire barrel 31 and the extension rod 33, so that the mobile phone can be better adsorbed on the first suction cup 24, and at the same time, the position of the first suction cup 24 adsorbed on the mobile phone can be ensured to be relatively uniform.

[0062] Embodiment three:

[0063] The outer ring surface of the column 25 is a smooth surface; the column 25 is slidably connected with a slip ring 26, and the slip ring 26 itself has a certain weight;

[0064] The pull rope 43 passes through the slip ring 26; the side of the pull rope 43 passing through the slip ring 26 is fixedly connected to the slip ring 26;

[0065] In this embodiment, the pull rope 43 is fixedly connected with evenly arranged counterweight blocks 45;

[0066] In this embodiment, the counterweight 45 is a round ball, and the surface of the round ball is smooth;

[0067] In this embodiment, a guide bin 34 is fixedly connected to the top of the drop platform 2 above the cylindrical groove 3; the side of the guide bin 34 facing the column 25 is an open design;

[0068] In this embodiment, a semicircular notch 35 is formed on a side of the wire tube 31 away from the first suction cup 24; and the semicircular notch 35 is located below the support ring 32;

[0069] Specifically, since the column 25 is slidably connected with the slip ring 26, and the pull rope 43 is fixedly connected to the slip ring 26, when the installation block 42 drives the pull rope 43 to move upward, the pull rope 43 will drive the slip ring 26 to move upward along the column 25, so the slip ring 26 can limit the pull rope 43, so that the pull rope 43 below the slip ring 26 is in line with the wire barrel 31. When the installation block 42 moves down, the installation block 42 no longer pulls the pull rope 43. At this time, the slip ring 26 will slide downward along the column 25 under its own gravity, and will drive the pull rope 43 to move downward. Since the pull rope 43 is fixedly connected with the evenly arranged counterweight blocks 45, when the slip ring 26 moves downward, the pull rope 43 also moves downward under the gravity of the counterweight blocks 45. Since the slip ring 26 limits the pull rope 43, the pull rope 43 moving downward will move downward along the wire barrel 31. 6 The distance that the pull rope 43 is driven to move downward gradually increases, and the pull rope 43 that falls into the wire barrel 31 gradually increases. Since a semicircular notch 35 is provided on the side of the wire barrel 31 away from the first suction cup 24, part of the pull rope 43 that falls into the wire barrel 31 will slide out of the semicircular notch 35 and extend to the outside under the gravity of the counterweight 45. Then, when the first suction cup 24 releases the mobile phone for testing, the mobile phone will fall downward under its own gravity. Since part of the pull rope 43 extends to the outside through the semicircular notch 35, during the process of the mobile phone falling, the pull rope 43 also falls downward and gradually unfolds under the gravity of the counterweight 45. Therefore, during the process of the mobile phone falling, it can be avoided that the pull rope 43 needs to be pulled downward when the mobile phone falls, which will affect the falling speed of the mobile phone and make it impossible to truly simulate the scene of the mobile phone being placed on the table.

[0070] More specifically, since the counterweight 45 is a round ball and the surface of the round ball is smooth, when the pull rope 43 drives the round ball to move down into the wire tube 31, the friction between the round ball and the wire tube 31 is small, so that the round ball can slide better in the wire tube 31 and the pull rope 43 can slide out of the semicircular groove 35 better. Since a guide bin 34 is provided above the cylindrical groove 3, the existence of the guide bin 34 can guide the pull rope 43 and allow the pull rope 43 to be introduced into the wire tube 31.

[0071] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
