The controller controls the falling device 100 to move up and down, controls the sucker 111 to suck the tested device 300, controls the angle adjusting mechanism 120 to adjust the angle of the picking mechanism 110, and controls the picking mechanism 110 to fall. A sensor assembly detecting height information of the falling device, angle information of the pickup mechanism 110, and transmitting the height information and the angle information to the controller.

Hereinafter, the device under test 300 will be described by taking a mobile phone as an example.

The control device controls the suction cup 111 to suck the mobile phone, so that the falling device 100 is lifted to a specified height. The angle adjusting mechanism 120 drives the second adjusting part 122 to rotate through the power assembly 121, the second adjusting part 122 is in contact connection with the first adjusting part 112, the first adjusting part 112 is fixedly connected with the sucker 111, the sucker 111 rotates by a specified angle, when the sucker 111 is adjusted to rotate by the specified angle, the angle information of the picking mechanism 110 is detected through the sensor assembly, and after the mobile phone reaches an angle required by a test, the controller controls the picking mechanism 110 to be released, so that the picking mechanism 110 can freely fall with the mobile phone. The height of the picking mechanism 110 is detected through the sensor assembly, when the specified height of releasing the mobile phone is reached, the mobile phone is controlled to be released through the controller, so that the mobile phone freely falls at a position lower than the ground, the possibility that the angle of the mobile phone is changed in the air is reduced, and the accuracy of test data is ensured.

Through the drop test equipment of above-mentioned structure, the height that can adjust the cell-phone and the angle when the cell-phone falls, the contact position of cell-phone and bottom surface after guaranteeing to fall can acquire effectual test data.

Further, as shown in fig. 3, the picking mechanism 110 further includes: a vacuum generator 113, the suction cup 111 being in communication with the vacuum generator 113.

The gas inside the pickup mechanism 110 is drawn by the vacuum generator 113 so that the suction cup 111 sucks the hand phone. Releasing the handset is accomplished by releasing the vacuum within the pick-up mechanism 110. The angle of the suction cup 111 is adjusted by rotating the first adjusting part 112, so that the mobile phone is rotated to the angle required by the test.

Further, the picking mechanism 110 further includes: an aerator 114 in communication with the suction cup 111.

When the mobile phone is released, a period of time is required from the release of the vacuum state inside the picking mechanism 110 to the equalization of the internal air pressure and the external air pressure, which may cause the picking mechanism 110 not to release the mobile phone in time, cause impact on the mobile phone, and affect the accuracy of the mobile phone drop test data. Therefore, the inflator 114 is provided to release the vacuum state inside the pickup mechanism 110 and to fill the pickup mechanism 110 with gas, so that the gas pressures inside and outside the pickup mechanism 110 are balanced as soon as possible, thereby instantaneously releasing the cellular phone.

Further, the pickup mechanism 110 is connected to the angle adjustment mechanism 120 through an electromagnetic mechanism.

As an example, as shown in fig. 3 and 4, the electromagnetic mechanism is constituted by a first electromagnetic member 115 provided on the pickup mechanism 110 and a second electromagnetic member 123 provided on the angle adjusting mechanism 120 in correspondence with the first electromagnetic member 115. When the first adjusting member 112 and the second adjusting member 122 are in contact with each other, the contact may be not tight, which may cause a slip phenomenon or mutual interference when the adjusting member sets rotate relatively, resulting in inaccurate rotation angle of the mobile phone and affecting the accuracy of the test. Therefore, in the present embodiment, the strength of the contact of the pickup mechanism 110 and the angle adjustment mechanism 120 is strengthened by the electromagnetic mechanism.

Further, as shown in fig. 2, the fall device 100 further includes a connection mechanism 130, as shown in fig. 5, the connection mechanism 130 includes: a support bracket 133 and a telescopic bracket 132. The support bracket 133 is connected to the angle adjustment mechanism 120. The telescoping bracket 132 is connected to the support bracket 133 and detachably connected to the picking mechanism 110.

The supporting frame 133 has a fork-shaped structure, and supports the angle adjusting mechanism 120 through fork plates at both sides. The telescopic frame 132 supports the pickup mechanism 110 from below the pickup mechanism 110. As an example, the telescopic frame 132 may be implemented by a cylinder mechanism, and the piston is extended to support the picking mechanism 110, and the piston is retracted into the cylinder to release the picking mechanism 110 so as to be separated from the angle adjusting mechanism 120.

As an embodiment, as shown in fig. 4, the power assembly 121 of the angle adjusting mechanism 120 includes a motor and a transmission mechanism, the transmission mechanism may adopt any type of mechanism, taking a belt transmission mechanism as an example, a main shaft of the motor is connected with a driving wheel, the driving wheel and a driven wheel are connected through a transmission belt, and the second adjusting component 122 is coaxially connected with the driven wheel. During the test, if the angle adjusting mechanism 120 and the picking mechanism 110 fall together, the motor is impacted when the angle adjusting mechanism falls to the bottom, and the service life of the motor is shortened. Therefore, the angle adjusting mechanism 120 and the picking mechanism 110 are made into a split type, and only the picking mechanism carries the mobile phone to fall down, so that the damage of the motor can be avoided.

Further, as shown in fig. 1, the drop test device further includes a lifting device 200, which includes a transmission mechanism 210 and a guide mechanism 220. And a transmission mechanism 210 connected to the connection mechanism 130 for driving the connection mechanism 130 to move up and down. The guide mechanism 220, the angle adjusting mechanism 120 and the picking mechanism 110 are slidably disposed up and down on the guide mechanism 220.

Specifically, the transmission mechanism 210 includes a motor and a transmission assembly, and the transmission assembly may be any type of structure capable of transmitting power of the motor. The driving assembly is a belt driving assembly, and includes a driving belt, the connecting mechanism 130 is connected to the driving belt through a connecting member 131 disposed on the connecting mechanism 130, and the other end of the connecting member 131 is connected to the supporting frame 133 and the expansion bracket 132. When the connecting mechanism 130 connects the picking mechanism 110 and the angle adjusting mechanism 120 at the same time, the up-and-down movement can be realized by the driving of the transmission mechanism.

The guiding mechanism 220 may be a vertically arranged guiding rod, as shown in fig. 3 and 4, the picking mechanism 110 is provided with a first guiding tube 116, the angle adjusting mechanism 120 is provided with a second guiding tube 124, the first guiding tube 116 and the second guiding tube 124 are slidably sleeved on the outer circumferential surface of the guiding rod, and the guiding rod guides the up-and-down movement of the picking mechanism 110 and the angle adjusting mechanism 120.

Preferably, there are two guide rods arranged in parallel, and there are two corresponding first guide tubes 116 and second guide tubes 124.

The lifting device 200 further comprises a buffer 230 disposed below the falling device 100.

When the picking mechanism 110 falls to the bottom, an impact force is generated, and the buffer 230 is arranged at the bottom of the lifting device 200 to counteract the impact force, so that the picking mechanism 110 slowly falls, the picking mechanism 110 is prevented from being damaged, and the service life is prolonged.

As shown in fig. 6, a method for testing the damage degree of a tested device after falling through the falling test equipment comprises the following steps:

s100, forming a vacuum state in the picking mechanism by extracting gas in the picking mechanism, sucking the tested device through the picking mechanism, and lifting the tested device to a specified height;

s200, the power assembly drives the adjusting component group to rotate, so that the picking mechanism rotates by a specified angle to adjust the angle of the tested device;

s300, driving the tested device to fall in a free-fall state through a picking mechanism, detecting position information of the picking mechanism, and controlling the picking mechanism to release the tested device according to the position information when the position reaches a specified height;

and S310, releasing the vacuum state of the picking mechanism.

And S320, filling gas into the picking mechanism. When the mobile phone is released, gas is filled into the picking mechanism, and the mobile phone can be released by releasing the vacuum state because the interior of the picking mechanism is in the vacuum state.

S400, detecting the appearance of the tested device and the designated parameters, and judging the damage degree of the tested device.

In this embodiment, a mobile phone drop test is taken as an example. After the mobile phone is picked up, the height required by the test is raised, and the mobile phone is subjected to a drop test. When the mobile phone falls, the damage degree of the mobile phone after different parts of the mobile phone are landed needs to be tested, so that the mobile phone is adjusted to rotate to a specified angle. And after the height and the angle are adjusted, the drop test can be carried out. However, due to the position of the center of gravity, the angle of the mobile phone may change during the falling process of the mobile phone, that is, the mobile phone may not always fall at an angle. Therefore, the mobile phone needs to be released after dropping to a certain height in a state where the pickup mechanism picks up the mobile phone.

The method ensures that the mobile phone can carry out a drop test at a specified height and a specified angle, ensures the contact position of the mobile phone and the ground after the drop, and can acquire effective test data.

In the test process, the picking mechanism picks up the mobile phone in various ways, for example, a clamping tool can be used for clamping the mobile phone, but if the clamping tool is not tightly clamped, the mobile phone falls off when the picking mechanism does not reach the height for releasing the mobile phone, so that the test result is inaccurate. If the clamping is too tight, the appearance of the mobile phone is damaged or internal components are damaged, so that the true cause of the damage cannot be judged, and the result of inaccurate test result is also brought.

Therefore, in the present embodiment, it is preferable to adopt a manner in which the pickup tool sucks the mobile phone. The air in the picking mechanism is pumped out, the mobile phone is sucked, the mobile phone can be firmly picked, and damage of the mobile phone caused by picking can be avoided.

As an embodiment, the first adjusting member 112 may be a first friction roller, and the second adjusting member 122 may be a second friction roller.

A first friction roller is arranged on the picking mechanism 110, a second friction roller is arranged on the power assembly 121, and the power assembly 121 drives the second friction roller to rotate. The first friction roller is in flexible contact with the second friction roller, so that the first friction roller rotates along with the second friction roller, and the function of adjusting the rotation of the pickup mechanism 110 to a specified angle is realized.

First friction gyro wheel and second friction gyro wheel all adopt flexible gyro wheel, increase the area of contact between first friction gyro wheel and the second friction gyro wheel, increase frictional force, for the line contact between the rigidity friction gyro wheel can more effectively rotate through the first friction gyro wheel of frictional force drive, realize the regulation to picking up the angle of mechanism 110.

The first friction roller and the second friction roller may be integrally formed as a flexible roller, for example, made of rubber, or the roller shaft may be a rigid shaft, which may increase the rigidity of the friction roller, and a flexible sleeve, for example, a rubber tube, may be sleeved on the outer circumferential surface of the rigid shaft.

The drop test equipment can be used for carrying out drop tests on products such as mobile phones, tablet computers, notebook computers and displays, the angles of lighter products such as mobile phones and the like can be adjusted through the roller group, and when the products such as the displays and the like are subjected to drop tests, the slipping phenomenon is easy to occur when the angles are adjusted through the friction roller group. Therefore, as another embodiment, the first adjustment component 112 may be a first gear, and the second adjustment component 122 may be a second gear, and after the two gears are meshed, the first gear is driven by the second gear to rotate, so as to achieve the angle adjustment.

When the two gears are meshed, the possibility of mutual interference of gear teeth exists, therefore, when the angle adjusting mechanism 120 and the picking mechanism 110 are connected through the connecting mechanism 130, the meshing condition of the two gears is detected through the sensor, meshing information is transmitted to the processor, a required rotating angle for ensuring that the second gear and the first gear can be meshed is calculated, a command for rotating the corresponding angle of the second gear is transmitted to the controller, and after the second gear rotates the required angle, the angle adjusting mechanism 120 and the picking mechanism 110 are connected through the connecting mechanism 130.

The height of the released mobile phone is not too high easily, so that the situation that the angle of the mobile phone is changed in the falling process is avoided, and the mobile phone is released after the picking mechanism is lowered to a certain height in the state of sucking the mobile phone. The mobile phone can be released by releasing the vacuum state in the picking mechanism, after the vacuum state is released, the air pressure in the picking mechanism gradually reaches the balance with the external atmospheric pressure, and at the moment, the mobile phone continues to freely fall to the ground under the action of self weight.

However, the process of releasing the vacuum state requires a certain time, and instantaneous release cannot be achieved. The height of the mobile phone released by the picking mechanism is low, so that the picking mechanism and the mobile phone are easily lowered to the bottommost part together, the impact of the picking mechanism and the ground on the mobile phone is caused, and the test data is inaccurate. In order to avoid the situation that the mobile phone is still kept in a state that the picking mechanism sucks the mobile phone when the mobile phone falls to the ground, the vacuum state is relieved, and meanwhile, gas is filled into the picking mechanism, so that the picking mechanism can quickly release the mobile phone.
