[0058] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.
[0059] The present embodiment provides a drop test device for drop testing a product to be tested.
[0060] In the present embodiment, the product to be tested is specifically an electronic watch. In other embodiments, the product to be tested can also be a mobile phone, a tablet computer, a smart head-mounted product, etc.
[0061] Please refer to Figures 1 to 7The falling test equipment comprises a turnover device 1, a falling impact seat 2, a first mechanical arm 3 and a falling grabbing assembly 4. The turnover device 1 is configured to turn over the product to be tested. The falling grabbing assembly 4 can grab or release the product to be tested. The falling grabbing assembly 4 is in transmission connection with the first mechanical arm 3. The first mechanical arm 3 drives the falling grabbing assembly 4 to move in space so that the falling grabbing assembly 4 has a first position above the positioning mechanism 11 and a second position above the falling impact seat 2. When the falling grabbing assembly 4 is in the first position, the falling grabbing assembly 4 is configured to grab the product to be tested supported by the positioning mechanism 11. When the falling grabbing assembly 4 is in the second position, the falling grabbing assembly 4 is configured to release the product to be tested. The falling test equipment provided in the embodiment can drive the falling grabbing assembly 4 to move to the first position and grab the product to be tested positioned by the positioning mechanism 11 through the first mechanical arm 3 during the falling test. Then, the falling grabbing assembly 4 is driven to move to the second position through the first mechanical arm 3, and the falling grabbing assembly 4 is released. The product to be tested freely falls and collides with the falling impact seat 2 below to simulate the falling of the electronic product in use and complete the falling test.
[0062] The falling test equipment can turn over the product to be tested through the turnover device 1, and adjust the posture of the product to be tested through the relative movement of each joint of the first mechanical arm 3 to make the product to be tested collide with the falling impact seat 2 below in different surfaces and postures, so as to ensure the comprehensiveness of the test. In addition, the product to be tested is positioned by the positioning mechanism 11 first, and then grabbed by the falling grabbing assembly 4, so as to ensure the accurate relative position between the product to be tested and the falling grabbing assembly 4, and further improve the falling test precision.
[0063] It should be noted that the material of the falling impact seat 2 can be selected according to actual needs. For example, cement material, marble material, wood material, asphalt material and the like can be used.
[0064] In some embodiments, please refer to Figure 5 The first mechanical arm 3 adopts a six-axis mechanical arm. The first mechanical arm 3 can make the product to be tested grabbed by the falling grabbing assembly 4 to assume various postures through the relative rotation of each joint. In other embodiments, the first mechanical arm 3 can also adopt a three-axis mechanical arm, a four-axis mechanical arm and the like.
[0065] In the related art, the position stability of the turnover device when turning over the product to be tested is poor, which leads to poor position precision of the product to be tested turned over by the turnover device, and further affects the position precision of the mechanical arm when clamping the product to be tested, thereby affecting the test precision.
[0066] For this purpose, please refer to Figures 1 to 4In this embodiment, the flipping device 1 includes a positioning mechanism 11, a flipping mechanism 12, and a lifting drive component 13. The flipping device 1 includes a first positioning component 111, a second positioning component 112, and a support base 113. The support base 113 is configured to support the product to be tested, and the first positioning component 111 is configured to position the product to be tested in a first direction (e.g., ...). Figure 1 The second positioning component 112 is configured to clamp or release the two ends of the product under test in the second direction (as indicated by the middle arrow ab), and is configured to position the product under test in the second direction (e.g., the direction indicated by the middle arrow ab). Figure 1 The two ends of the direction indicated by the middle arrow (cd) are clamped or loosened, the first direction and the second direction form an angle, and both the first direction and the second direction are perpendicular to the vertical direction (such as...). Figure 1 (The direction indicated by the arrow ef) is perpendicular; the flipping mechanism 12 includes a flipping drive 121 and a flipping gripping assembly 122 that is pulsatorically connected to the flipping drive 121. The flipping drive 121 drives the flipping gripping assembly 122 to rotate, and the flipping gripping assembly 122 is configured to grip or release the product under test; the lifting drive 13 is used to drive one of the positioning mechanism 11 and the flipping mechanism 12 to move closer to or further away from the other in a vertical direction. With this configuration, during the flipping of the product under test, after the product under test is placed on the support base 113, the first positioning assembly 111 clamps the product under test in a first direction, and the second positioning assembly 112 clamps the product under test in a second direction, which can accurately position the product under test. Therefore, after the flipping gripping assembly 122 clamps the product under test, the relative position between the product under test and the flipping gripping assembly 122 can be ensured to be accurate, thereby ensuring the positional accuracy of the product under test after the flipping gripping assembly 122 flips. In this embodiment, the lifting drive 13 is exemplarily connected to the tilting mechanism 12, and the tilting mechanism 12 is driven to move closer to or away from the positioning mechanism 11 in the vertical direction. In other embodiments, the lifting drive 13 may also be connected to the positioning mechanism 11, and the positioning mechanism 11 may be driven to move closer to or away from the tilting mechanism 12 in the vertical direction.
[0067] Specifically, in the embodiment, when the product to be tested is flipped, the product to be tested is first positioned by the first positioning assembly 111 and the second positioning assembly 112, then the product to be tested is grabbed by the flipping grabbing assembly 122 while the first positioning assembly 111 and the second positioning assembly 112 are loosened, then the flipping mechanism 12 and the product to be tested as a whole are separated from the positioning mechanism 11 by the lifting drive 13, then the flipping grabbing assembly 122 and the product to be tested as a whole are driven to have a certain angle of flip by the flipping drive 121, then the flipping mechanism 12 and the product to be tested as a whole are repositioned with the positioning mechanism 11 by the lifting drive 13, and the flipping grabbing assembly 122 is loosened to allow the product to be tested to be supported on the support seat 113 again, and the product to be tested is repositioned by the first positioning assembly 111 and the second positioning assembly 112 for grabbing by the falling grabbing assembly 4. In this way, the product to be tested is positioned by the positioning mechanism 11 before being flipped to ensure that the position of the product to be tested grabbed by the flipping grabbing assembly 122 is accurate, and the product to be tested is also positioned by the positioning mechanism 11 after being flipped to ensure that the position of the product to be tested grabbed by the falling grabbing assembly 4 is accurate.
[0068] In some embodiments, the flipping grabbing assembly 122 can flip the product to be tested by 180°. In other embodiments, the flipping grabbing assembly 122 can also flip the product to be tested by other angles.
[0069] In addition, it should be noted that, according to the actual test working condition, the product to be tested needs to be flipped in some working conditions, and the product to be tested does not need to be flipped in some working conditions. When the product to be tested does not need to be flipped, the product to be tested can be positioned by the first positioning assembly 111 and the second positioning assembly 112 after being placed on the support seat 113, and the positioned product to be tested can be grabbed by the falling grabbing assembly 4.
[0070] In some embodiments, the first direction is perpendicular to the second direction. In other embodiments, the included angle between the first direction and the second direction can also be set according to the actual situation of the product to be tested.
[0071] In some embodiments, the flipping device 1 further comprises a flipping workbench 14, and the positioning mechanism 11 and the lifting drive 13 are both mounted on the flipping workbench 14.
[0072] In some embodiments, please refer to Figure 3 and Figure 4 , the lifting drive 13 is a single-acting cylinder. In other embodiments, the lifting drive 13 can also be set as an electric push rod or a hydraulic cylinder, etc.
[0073] In some embodiments, please refer to Figure 3 and Figure 4The turnover driving member 121 is a rotary cylinder. In other embodiments, the turnover driving member 121 can also be a turnover motor or the like.
[0074] In some embodiments, referring to Figure 3 and Figure 4 The first positioning assembly 111 comprises a first driving member 1111 and two first clamping jaws 1112, the two first clamping jaws 1112 are in driving connection with the first driving member 1111, and the two first clamping jaws 1112 are spaced apart along a first direction. The first driving member 1111 is used to drive the two first clamping jaws 1112 to move close to or away from each other along the first direction. In this way, under the driving of the first driving member 1111, the two first clamping jaws 1112 can simultaneously clamp the product to be tested along the first direction, which can improve the positioning efficiency of the product to be tested.
[0075] In the embodiment, the first driving member 1111 is a double-rod cylinder. In other embodiments, the first driving member 1111 can also comprise a first motor and a first bidirectional screw rod in driving connection with the first motor. The first bidirectional screw rod is provided with a first forward thread and a first reverse thread. The two first clamping jaws 1112 are screwed to the forward thread and the reverse thread, respectively. The two first clamping jaws 1112 are in sliding connection with the support seat 113 along the first direction. When the first motor drives the first bidirectional screw rod to rotate, the first bidirectional screw rod drives the two first clamping jaws 1112 to move close to or away from each other.
[0076] As one of the alternative solutions, the first positioning assembly 111 comprises a first positioning driving member, a first positioning reference block and a first movable block. The first reference block is fixedly arranged on the support seat 113. The first movable block is slidingly arranged on the support seat 113. The first positioning driving member is in driving connection with the first movable block. The first positioning driving member can drive the first movable block to move close to or away from the first reference block along the first direction, which can also achieve clamping or loosening of the product to be tested.
[0077] In some embodiments, referring to Figure 3 and Figure 4 The first clamping jaw 1112 comprises a first base plate 1113 in driving connection with the first driving member 1111, and two first clamping blocks 1114 fixedly connected with the first base plate 1113. The two first clamping blocks 1114 are spaced apart along a second direction and form a first empty slot 1115. In this way, the first clamping jaw 1112 can clamp the product to be tested through the two first clamping blocks 1114, which can ensure stable positioning effect and can avoid the local structure of the product to be tested through the first empty slot 1115. In addition, only the two first clamping blocks 1114 of the first clamping jaw 1112 need to be finished during processing, which reduces the processing difficulty.
[0078] In some embodiments, please refer to Figure 4 The first substrate 1113 and the two first clamping blocks 1114 are integrally formed in some embodiments. In other embodiments, the first substrate 1113 and the two first clamping blocks 1114 can also be separately arranged.
[0079] In some embodiments, please refer to Figure 3 and Figure 4 The turnover grabbing assembly 122 can rotate under the driving of the turnover driving member 121 to have an initial position and a turnover position. The turnover grabbing assembly 122 includes a grabbing driving member 1221 and two grabbing clamps 1222. The two grabbing clamps 1222 are arranged at intervals and are in transmission connection with the grabbing driving member 1221. When the turnover grabbing assembly 122 is located at the initial position, the two grabbing clamps 1222 are arranged at intervals along the first direction, and the grabbing driving member 1221 can drive the two grabbing clamps 1222 to enter the two first empty slots 1115 along the first direction respectively to clamp the product to be tested. When the turnover grabbing assembly 122 moves from the initial position to the turnover position, the two grabbing clamps 1222 are arranged at intervals along the first direction, and the grabbing driving member 1221 can drive the two grabbing clamps 1222 to exit the two first empty slots 1115 along the first direction respectively to separate from the product to be tested. In this way, the first empty slot 1115 can also be used for avoiding position when the grabbing clamp 1222 grabs the product to be tested, which improves the compactness of the turnover mechanism 12. In other embodiments, the grabbing clamp 1222 in the turnover grabbing assembly 122 can also be replaced by a vacuum suction cup.
[0080] It should be noted that in the present embodiment, the turnover grabbing assembly 122 can drive the grabbing driving member 1221 to turn 180°, so that the two grabbing clamps 1222 are arranged at intervals along the first direction when the turnover grabbing assembly 122 is located at the initial position and the turnover position.
[0081] In the present embodiment, the grabbing driving member 1221 is a double-rod cylinder. In other embodiments, the grabbing driving member 1221 can also include a second motor and a second bidirectional screw rod in transmission connection with the second motor. The second bidirectional screw rod is provided with a second forward thread and a second reverse thread. The two grabbing clamps 1222 are screwed to the forward thread and the reverse thread respectively, and the two grabbing clamps 1222 can slide relative to the shell of the lifting driving member 13. When the second motor drives the second bidirectional screw rod to rotate, the second bidirectional screw rod drives the two grabbing clamps 1222 to move closer to or farther away from each other. Optionally, the turnover grabbing assembly 122 further includes a connecting block 1223. The grabbing driving member 1221 is connected with the turnover driving member 121 through the connecting block 1223. The turnover driving member 121 drives the connecting block 1223 to rotate to drive the grabbing driving member 1221 to rotate synchronously, so as to switch the turnover grabbing assembly 122 between the initial position and the turnover position.
