Description

Technical Field

[0001] The present application relates to the field of electronic testing equipment, and in particular to a directional drop test equipment with adjustable release height. Background Art

[0002] After being manufactured, commonly used electronic products need to undergo a drop test to test the product's drop resistance and the extent of damage to the product's internal components.

[0003] The current drop test equipment fixes the photoelectric sensor at a single height, resulting in a fixed release height of the drop test equipment. If the height does not meet the standard requirements, the photoelectric sensor part needs to be disassembled and re-fixed.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the height of the drop test is fixed, which is not conducive to adjusting the height and cannot meet the requirements of various release heights. Summary of the invention

[0005] In order to change the release height of the drop test equipment in real time, the present application provides a directional drop test equipment with adjustable release height.

[0006] The present application provides a directional drop test device with adjustable release height, which adopts the following technical solution:

[0007] A directional drop test device with adjustable release height comprises a protection box and a controller, wherein a positioning mechanism that slides in a vertical direction and is used to clamp an object to be tested is arranged in the protection box, a lifting mechanism is arranged in the protection box and on one side of the positioning mechanism, the lifting mechanism is electrically connected to the controller, a photoelectric sensor is connected to the lifting mechanism, a baffle adapted to the photoelectric sensor is arranged on the positioning mechanism, and the positioning mechanism and the photoelectric sensor are both electrically connected to the controller.

[0008] By adopting the above technical solution, the photoelectric sensor and the baffle are adapted. When the baffle blocks the signal emitted by the photoelectric sensor, the photoelectric sensor transmits the blocking information to the controller. The controller can control the positioning mechanism to release, so that the object to be tested falls at a specified height. This process is controlled by the controller, so that the test results are more accurate, and the controller controls the lifting mechanism in real time, thereby changing the height of the photoelectric sensor, and then changing the height at which the positioning mechanism releases the object to be tested.

[0009] Preferably, the lifting mechanism includes a first lifting rod, a first driving assembly, a screw rod and a slider, the first lifting rod is connected in a protective box, the screw rod is rotatably connected to the first lifting rod, the first driving assembly is connected to the top of the first lifting rod, the first driving assembly is connected to the top of the screw rod and is used to drive the screw rod to rotate, the first driving assembly is electrically connected to the controller, the slider is connected to the screw rod, and the photoelectric sensor is connected to the slider.

[0010] By adopting the above technical solution, the lead screw rotates and the slider moves along the length direction of the lead screw, thereby changing the height of the photoelectric sensor and further changing the height at which the positioning mechanism releases the object to be measured.

[0011] Preferably, a first vertical lifting plate is connected to one side of the first lifting rod, the screw rod is located between the first lifting plate and the first lifting rod, and the top and bottom surfaces of the slider are penetrated at both ends of the first lifting plate.

[0012] By adopting the above technical solution, the first lifting plate further limits the position of the slider, so that the slider will not flip when moving along the length direction of the lead screw, thereby facilitating the movement of the slider.

[0013] Preferably, a side wall of the sliding block away from the first lifting rod is connected to a second lifting plate, and the photoelectric sensor is connected to the second lifting plate.

[0014] By adopting the above technical solution, the photoelectric sensor needs to be inspected when it is used for a long time, and it needs to be disassembled during the inspection. Since the photoelectric sensor needs to be installed with relevant wires for adaptation, the second lifting plate is directly disassembled together with the photoelectric sensor during the inspection to facilitate subsequent installation.

[0015] Preferably, a third lifting plate is connected to the side of the second lifting plate connected to the slider, and the blocking piece is arranged between the third lifting plate and the second lifting plate.

[0016] By adopting the above technical solution, a third lifting plate is added to limit the position where the baffle plate passes through, so that the movement path of the baffle plate is limited.

[0017] Preferably, a second lifting rod is provided in the protection box, and the first lifting rod is connected to the second lifting rod.

[0018] By adopting the above technical solution, the lifting mechanism needs to be inspected and repaired after being used for a period of time. It is troublesome to disassemble the lifting mechanisms one by one. The first lifting rod can be disassembled so that the lifting mechanisms can be removed simultaneously. The disassembly process will not affect the lifting mechanism, thereby reducing the possibility of damage to the lifting mechanism during the disassembly process.

[0019] Preferably, the top of the first lifting rod is higher than the top of the second lifting rod, and there is a distance between the bottom of the first lifting rod and the bottom surface of the protection box.

[0020] By adopting the above technical solution, the first lifting rod is added to increase the height of the second lifting rod.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] The photoelectric sensor and the baffle are adapted. When the baffle blocks the signal emitted by the photoelectric sensor, the photoelectric sensor transmits the blocking information to the controller. The controller can control the positioning mechanism to release so that the object to be measured falls at a specified height. This process is controlled by the controller. The controller controls the lifting mechanism in real time to change the height of the photoelectric sensor, thereby changing the height of the positioning mechanism to release the object to be measured.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-8 This application is described in further detail.

[0034] The embodiment of the present application discloses a directional drop test device with adjustable release height.

[0035] Example 1

[0036] Reference Figure 1The directional drop test equipment with adjustable release height includes a protection box 6 and a controller. In the present embodiment, the protection box 6 includes a first protection plate 61 and a second protection plate 62 which are arranged opposite to each other in upper and lower directions. The first protection plate 61 and the second protection plate 62 are connected by four first protection rods 63, wherein a protection opening 64 is formed between adjacent first protection rods 63, and a third protection plate 65 is connected between the other adjacent first protection rods 63, that is, the number of the third protection plates 65 is three; in order to enhance the overall connection stability, a second protection rod 66 with a cross-shaped vertical section is fixed on the adjacent first protection rods 63 and corresponding to the third protection plate 65; in order to facilitate the observation of the test conditions in the protection box 6, the first protection plate 61, the second protection plate 62 and the third protection plate 65 are all transparent.

[0037] Reference Figure 1 In order to reduce the size of the protection opening 64, a fourth protection plate 67 is connected to the adjacent first protection rod 63 and corresponding to the protection opening 64. The fourth protection plate 67 is transparent. A protection door 68 is rotatably connected to the adjacent first protection rod 63 and corresponding to the protection opening 64. There is a gap between the top of the protection door 68 and the bottom of the fourth protection plate 67.

[0038] Reference Figure 1 The second protection plate 62 is connected with a positioning mechanism 7 which slides in the vertical direction and is used to clamp the object to be measured.

[0039] Reference Figure 1 and Figure 2The positioning mechanism 7 includes a first positioning plate 71 and a second positioning plate 72 which are arranged opposite to each other in the upper and lower directions. The first positioning plate 71 and the second positioning plate 72 are connected by four first positioning rods 721, wherein the spacing formed by two first positioning rods 721 and the protective opening 64 is greater than the spacing formed by the other two second positioning rods and the protective opening 64. The connecting lines of the connecting points of the four first positioning rods 721 and the second positioning plate 72 form an isosceles trapezoid. The two first positioning rods 721 near the protective opening 64 are slidably connected with first sliders 722 which are arranged in the upper and lower directions. The first positioning plate 71 and the second positioning plate 72 are connected with a second driving assembly 724 that drives the first slider 722 to move in the vertical direction. The second driving assembly 724 includes a third motor 725 and a second sprocket set 726. The third motor 725 is connected to the second positioning plate 72. The third motor 725 is electrically connected to the controller. The second sprocket set 726 is connected to the first positioning plate 71 and the second positioning plate 72. The second sprocket set 726 is connected to the first slider 722 so that the first slider 722 can move in the vertical direction. The first slider 722 is embedded with an electromagnet. When the first slider 722 is energized so that the electromagnet generates magnetism, the first slider 722 and the second slider 723 attract each other. During the test, the first slider 722 is energized so that the first slider 722 and the second slider 723 attract each other in order to provide acceleration for the second slider 723. When the first slider 722 moves to a specified height, the first slider 722 stops. Due to inertia, the first slider 722 and the second slider 723 may collide with each other. In order to reduce the degree of damage, the first slider 722 is immediately powered off after the first slider 722 stops, so that the first slider 722 and the second slider 723 are separated.

[0040] Reference Figure 1 and Figure 3 The second slider 723 is connected to a horizontally arranged first limit plate 73 on the side wall near the protective opening 64, and a first limit groove 731 is opened on the side wall of the first limit plate 73 near the protective opening 64. Two oppositely arranged second limit plates 74 are slidably connected to the first limit plate 73, one end of the second limit plate 74 extends into the first limit groove 731, and the other end extends out of the first limit groove 731. The top of the first limit plate 73 is connected to a first pin 741 for limiting the position of the second limit plate 74.

[0041] Reference Figure 3 Two third limiting plates 75 arranged opposite to each other are slidably connected to the first limiting plate 73 , one end of the third limiting plate 75 extends into the first limiting groove 731 , and the other end extends out of the first limiting groove 731 . The two third limiting plates 75 are located between the two second limiting plates 74 .

[0042] Reference Figure 4The second limiting plate 74 is connected to a third cylinder 742 for driving the corresponding third limiting plate 75 to slide. The output end of the third cylinder 742 is connected to the side wall of the third limiting plate 75 close to the corresponding second limiting plate 74, and the third cylinder 742 is electrically connected to the controller.

[0043] Reference Figure 4 The sides of the two third limiting plates 75 that are close to each other are connected to the fourth limiting plates 76, and the sides of the two fourth limiting plates 76 that are close to each other are connected to the fifth limiting plates 77. The side walls of the fifth limiting plates 77 away from the fourth limiting plates 76 are provided with second limiting grooves 771. The second limiting grooves 771 can be horizontal grooves or grooves with angles. In this embodiment, the angle of one of the second limiting grooves 771 is 3° and the angle of the other second limiting grooves 771 is 5°, so as to control the angle of the object to be tested when it falls.

[0044] Reference Figure 4 When clamping, in order to protect the object to be measured, the bottom of the fourth limit plate 76 is rotatably connected to the third rotation shaft, the bottom of the fourth limit plate 76 is flush with the bottom of the fifth limit plate 77, and the side wall of the third rotation shaft is connected to the sixth limit plate 761, the length of the sixth limit plate 761 is equal to the length of the fourth limit plate 76, and the third rotation shaft is close to the protection port 64 (refer to Figure 1 ) is connected to the end of the first disc 762, and the first disc 762 and the fourth limiting plate 76 are plugged with a second latch 763. When the sixth limiting plate 761 is in a vertical shape, the sixth limiting plate 761 and the fourth limiting plate 76 are located on the same vertical plane. When the sixth limiting plate 761 is in a horizontal shape, the sixth limiting plate 761 and the fourth limiting plate 76 are in a right angle shape. The side wall of the sixth limiting plate 761 abuts against the bottom surface of the fifth limiting plate 77. At this time, the distance between the two sixth limiting plates 761 is smaller than the distance between the two fifth limiting plates 77. The sixth limiting plate 761 plays a supporting role for the object to be tested. Before the test, it is necessary to adjust the rotation angle of the sixth limiting plate 761 so that the sixth limiting plate 761 and the fourth limiting plate 76 are located on the same vertical plane to prevent the sixth limiting plate 761 from hindering the object to be tested from falling.

[0045] Reference Figure 4The falling angle of some objects to be tested needs to be limited, so the clamping angle of the objects to be tested needs to be adjusted. The side wall of the fourth limiting plate 76 away from the fifth limiting plate 77 is connected to a seventh limiting plate 764 with a fan-shaped vertical section, and the seventh limiting plate 764 is connected to an eighth limiting plate 765. One end of the eighth limiting plate 765 is connected to a third latch 766 and the other end is connected to a fifth latch 767. The third latch 766 penetrates the fourth limiting plate 76 and extends out of the side wall of the fifth limiting plate 77. The eighth limiting plate 765 is connected to a fourth latch abutting against the outer wall of the third latch 766. The third latch 766 and the fifth latch 767 are connected to the fourth limiting plate 76 and extend out of the side wall of the fifth limiting plate 77. The eighth limiting plate 765 is connected with a sixth latch 769 that abuts against the outer side wall of the fifth latch 767. The fourth limiting plate 76 and the fifth limiting plate 77 are both provided with an arc hole 772 for the fifth latch 767 to penetrate and slide. The eighth limiting plate 765 and the seventh limiting plate 764 are connected with a seventh latch 78 for limiting the rotation angle of the eighth limiting plate 765. When the falling angle of the object to be measured needs to be adjusted, the third latch 766 and the fifth latch 767 extend out of the side wall of the fifth limiting plate 77. When the falling angle of the object to be measured is horizontal, the third latch 766 and the fifth latch 767 are retracted into the side wall of the fifth limiting plate 77, so as not to affect the clamping of the object to be measured.

[0046] Reference Figure 2 A lifting mechanism 8 is connected to the top surface of the second protection plate 62 and located on one side of the first positioning rod 721 .

[0047] Reference Figure 2 and Figure 3 The lifting mechanism 8 is connected to a photoelectric sensor 81, and the side wall of the second slider 723 close to the lifting mechanism 8 is connected to a blocking piece 727 adapted to the photoelectric sensor 81, and the photoelectric sensor 81 is electrically connected to the controller.

[0048] Reference Figure 5 and Figure 6 The lifting mechanism 8 includes a first lifting rod 82, a first driving assembly 83, a screw rod 84 and a slider 85. The first lifting rod 82 is vertically arranged, the first lifting rod 82 is connected to the top surface of the second protective plate 62, the screw rod 84 is rotatably connected to the first lifting rod 82, the top surface of the first lifting rod 82 is connected with a first cross plate 821, the first driving assembly 83 is connected to the first cross plate 821, the first driving assembly 83 is connected to the top of the screw rod 84 and is used to drive the screw rod 84 to rotate, the slider 85 is connected to the screw rod 84, the photoelectric sensor 81 is connected to the slider 85, the first driving assembly 83 is driven to make the screw rod 84 rotate, and the slider 85 moves along the length direction of the screw rod 84.

[0049] Reference Figure 5 and Figure 6The first driving assembly 83 includes a second motor 831 and a first sprocket set. The second motor 831 is connected to the bottom surface of the first horizontal plate 821 and is located on one side of the first lifting rod 82. The second motor 831 is connected to the controller. The first sprocket set is connected to the first horizontal plate 821 and is connected to the output shaft of the second motor 831. The top end of the screw rod 84 is connected to the first sprocket set.

[0050] Reference Figure 5 and Figure 6 In order to further limit the sliding position of the slider 85, the side wall of the first lifting rod 82 is connected to a horizontal second cross plate 822, and the first cross plate 821 and the second cross plate 822 are connected to a vertical first lifting plate 823. The screw rod 84 is located between the first lifting plate 823 and the first lifting rod 82. The top and bottom surfaces of the slider 85 are penetrated at both ends of the first lifting plate 823, and the slider 85 slides along the first lifting plate 823.

[0051] Reference Figure 6 The side wall of the slider 85 away from the first lifting rod 82 is connected to the second lifting plate 851, the second lifting plate 851 is vertically arranged, the side where the second lifting plate 851 and the slider 85 are connected is connected to the third lifting plate 852, the photoelectric sensor 81 is connected to the second lifting plate 851 and the third lifting plate 852, the baffle 727 (refer to Figure 3 ) is arranged between the third lifting plate 852 and the second lifting plate 851.

[0052] Reference Figure 6 The top surface of the second protective plate 62 is connected to the second lifting rod 86, the first lifting rod 82 is connected to the second lifting rod 86, the top of the first lifting rod 82 is higher than the top of the second lifting rod 86, and there is a gap between the bottom of the first lifting rod 82 and the top surface of the second protective plate 62.

[0053] Reference Figure 1 The two first protection rods 63 located on the protection opening 64 are connected with infrared sensors 631. The infrared sensors 631 are located between the protection door 68 and the fourth protection plate 67. The infrared sensors 631 are electrically connected to the controller. During the test, when the two infrared sensors 631 sense that objects from the outside have entered the protection box 6, the infrared sensors 631 can transmit signals to the control box, and the control box immediately suspends the test to ensure the safety of the operation and the safety of the experimenter.

[0054] The implementation principle of Example 1 is as follows: before the test, first adjust the position of the first limit plate 73 so that the position of the corresponding second limit plate 74 changes, then rotate the sixth limit plate 761 to make it horizontal, and control the second cylinder 33 through the controller, so that the two fourth limit plates 76 clamp the object to be tested, and then rotate the sixth limit plate 761 to make it vertical. The controller controls the height of the photoelectric sensor 81, and the second sprocket group 726 drives the first slider 722 to move so that the second slider 723 moves synchronously. When the baffle 727 passes through the photoelectric sensor 81 and blocks the signal sent by the photoelectric sensor 81, the first slider 722 is powered off. At this time, the first slider 722 and the second slider 723 are separated, and the two sixth limit plates 761 are loosened at the same time, and the object to be tested falls. The second motor 831 can be controlled in real time by the controller to change the position of the slider 85, that is, the height of the photoelectric sensor 81 changes.

[0055] Example 2

[0056] Reference Figure 7 and Figure 8 The difference between this embodiment and embodiment 1 is that a receiving plate 2 is slidably connected on the second protective plate 62 and below the fifth limiting plate 77, a flipping mechanism 3 is connected at the center of the top surface of the receiving plate 2, a receiving frame 4 is connected to the flipping mechanism 3, and the cross-section of the receiving frame 4 is in the shape of a U-shaped letter "U". The flipping mechanism 3 is used to drive the receiving frame 4 to flip so that the receiving frame 4 adapts to the falling position of the object to be tested.

[0057] Reference Fig. 9 A soft first test board 41 is fixed on the inner side of the receiving frame 4, and a second test board 42 and a third test board 43 are respectively connected to the inner side of the receiving frame 4 and located on both sides of the first test board 41. The receiving frame 4 is connected to a plurality of clamping mechanisms 5 for clamping the first test board 41 and the second test board 42.

[0058] Reference Figure 7 and Fig. 9In order to facilitate pushing the receiving plate 2, the first protective plate 61 is connected with a first cylinder 1 that pushes the receiving plate 2 to slide along the top surface of the first protective plate 61. The first cylinder 1 is electrically connected to the controller. The first test plate 41 or the second test plate 42 or the third test plate 43 is located below the object to be tested by the pushing of the first cylinder 1. According to actual needs, the flip mechanism 3 is adjusted so that the third test plate 43 or the second test plate 42 faces the object to be tested. During normal testing, the third test plate 43 and the second test plate 42 are arranged relative to each other. During abnormal testing, that is, when a height adjustment error occurs or the clamping position of the object to be tested is exceeded, the third test plate 43 and the second test plate 42 are arranged relative to each other. When there is a problem such as an error in the placement and needs to be retested, the clamping mechanism 5 is adjusted so that the second test board 42 or the third test board 43 facing the first protection plate 61 falls onto the receiving plate 2, the clamping mechanism 5 resumes the clamping state, and the flipping mechanism 3 moves so that the first test board 41 faces the object to be tested, and the object to be tested directly falls onto the soft first test board 41, which has a protective effect on the object to be tested, and then the test is re-performed to reduce the waste of resources. In fact, the device will set an emergency stop mechanism to immediately cut off the power and shut down the entire device, but repeated shutdown operations will cause irreversible damage to the components, so the above structure is proposed for protection.

[0059] The flipping mechanism 3 includes a rack 31, a first gear 32 and a second cylinder 33. The rack 31 is slidably connected to the top surface of the receiving plate 2. The sliding direction of the rack 31 is parallel to the sliding direction of the receiving plate 2. The second cylinder 33 is connected to the top surface of the receiving plate 2 and is connected to the rack 31. The second cylinder 33 is electrically connected to the controller. A vertical first connecting plate 34 is connected to the top surface of the receiving plate 2 and is located between the rack 31 and the first positioning rod 721. A horizontal first rotating shaft 35 is rotatably connected to the first connecting plate 34. The length direction of the first rotating shaft 35 is perpendicular to the length direction of the rack 31. The first gear 32 is connected to the first rotating shaft 35 and meshes with the rack 31. A first bevel gear 36 is connected to the first rotating shaft 35, and a second connecting plate 37 is connected to the first rotating shaft 35 and located between the first gear 32 and the first bevel gear 36. The second connecting plate 37 is L-shaped, and the end of the second connecting plate 37 away from the first rotating shaft 35 is rotatably connected to the second rotating shaft 38. Both ends of the second rotating shaft 38 extend out of the side walls of the second connecting plate 37, and one end of the second rotating shaft 38 is connected to the second bevel gear 39 meshing with the first bevel gear 36, and the receiving frame 4 is connected to the second rotating shaft 38. According to actual needs, the second cylinder 33 is driven to move the rack 31, and the rack 31 pushes the first gear 32 to rotate, which drives the second connecting plate 37 to flip, and the first bevel gear 36 and the second bevel gear 39 cooperate to flip the receiving frame 4. The axis direction formed by the flipping of the second connecting plate 37 is perpendicular to the axis direction formed by the flipping of the receiving frame 4. When the second connecting plate 37 flips to a horizontal state, the first test plate 41 is horizontal. When the second connecting plate 37 is tilted, the first test plate 41 is tilted, and its tilt faces two directions, so that it corresponds to certain special road surface structures. In the actual installation process, the third test plate 43 and the second test plate 42 themselves are heavy, and the position of the device is uncontrollable. The receiving frame 4 can be flipped to a place away from the wall for installation through the flipping mechanism 3.

[0060] Reference Figure 8 and Fig. 9The clamping mechanism 5 includes a first clamping rod 51, two elastic ropes 52, two springs 53 and two second clamping rods 54. The first clamping rod 51 is rotatably connected to the side of the receiving frame 4. The length direction of the first clamping rod 51 is parallel to the length direction of the first rotating shaft 35. The two springs 53 are connected to the receiving frame 4 and are located above and below the corresponding first clamping rod 51. The length direction of the connecting line of the two springs 53 is parallel to the thickness direction of the receiving frame 4. The second clamping rod 54 is L-shaped, and one end of the second clamping rod 54 is connected to the corresponding elastic rope 52. The spring 53 is close to the end of the first clamping rod 51, and the second clamping rod 54 extends out of the end of the receiving frame 4 to adapt to the corresponding second test plate 42 and the third test plate 43. One end of the elastic rope 52 is connected to the first clamping rod 51, and the other end is connected to the corresponding second clamping rod 54. The two second clamping rods 54 of the same group clamp the second test plate 42 and the third test plate 43 in the receiving frame 4, and the receiving frame 4 is connected to the first motor 55. The output shaft of the first motor 55 is connected to the first clamping rod, and the first motor 55 is electrically connected to the controller. During normal testing, the first motor 55 drives the elastic rope 52 to tighten so that the two second clamping rods 54 of the same group clamp the second test plate 42 and the third test plate 43; when a fault occurs during the testing process, the first test plate 41 needs to be directed toward the object to be tested, and the first motor 55 drives the elastic rope 52 to loosen, and the spring 53 causes the two second clamping rods 54 of the same group to move away from each other. At this time, the second test plate 42 or the third test plate 43 located below falls onto the receiving plate 2, and then the flipping mechanism 3 is controlled to make the first test plate 41 face the object to be tested, and the object to be tested falls onto the first test plate 41 without causing damage.

[0061] The implementation principle of Example 2 is as follows: according to actual needs, the flipping mechanism 3 is adjusted so that the second test plate 42 or the third test plate 43 faces the object to be tested, and then a drop test is performed; when a failure occurs in the test, the clamping mechanism is adjusted so that the second test plate 42 or the third test plate 43 falls onto the receiving plate 2, and the flipping mechanism 3 is adjusted so that the first test plate 41 faces the object to be tested, and the object to be tested falls onto the soft first test plate 41, which protects the object to be tested, and then the test is performed again to reduce waste of resources.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
