Further, in order to ensure that the angle of the to-be-detected sample when the clamping portion 32 is transferred does not change in the clamped process, and the to-be-detected sample can be in a stable state, referring to fig. 3, in this embodiment, an elastic pad 2113 is disposed on a side where the two clamping arms 2112 are close to each other, and the elastic pad 2113 may be made of rubber, silica gel, or an EVA material (shore a30 ± 5 degrees), so that when the to-be-detected sample is clamped by the pickup portion 211, the elastic pad 2113 is elastically deformed, so that the to-be-detected sample can be attached to the elastic pad 2113, and the friction resistance during clamping is increased, thereby preventing the two clamping arms 2112 and the to-be-detected sample from slipping or slightly changing in posture (angle) in the lifting process.

Specifically, after being released, the sample to be tested collides with the ground or a falling plate arranged on the ground, and the sample to be tested is subjected to a reverse acting force from the ground and bounces to a certain height. The stroke can be selected as required, the pressure bearing areas of the two sides of the piston of the double-rod double-acting air cylinder are equal, and the movement speeds and the strokes of the two sides are the same, so that the balance of the clamping forces applied to the two sides of the sample to be detected is ensured, the mutual distance speed of the two clamping arms 2112 is higher, and the probability that the sample to be detected bounces and collides with the two clamping arms 2112 is reduced.

Specifically, referring to fig. 1 and fig. 4, in this embodiment, the pickup mechanism 21 further includes a fixing seat 212 disposed on the slide rail 22, and a positioning element 213 for connecting the fixing seat 212 and the pickup portion 211, wherein the positioning element 213 and the fixing seat 212 can be disposed in a clutch manner, so that the pickup portion 211 can be disposed in a clutch manner relative to the fixing seat 212, the pickup mechanism 21 further includes a sensor, the sensor is disposed on the slide rail 22 at an interval, and is triggered when the pickup portion 211 approaches, and the pickup mechanism 21 further includes a control circuit electrically connected to the sensor and the first driver 25, so as to control the first driver 25 to release the sample to be tested when the pickup portion 211 slides downward to trigger the sensor. Specifically, the fixing seat 212 may be arranged to be vertically adjustably mounted on the slide rail 22, and the timing belt 24 is connected to the fixing seat 212; the positioning member 213 may be disposed on one of the fixed base 212 and the pickup portion 211, and the body of the other of the fixed base 212 and the pickup portion 211 itself or a structure cooperating with the positioning member 213 may be disposed on the body. It should be noted that the control circuit is electrically connected to the sensor and the first driver 25 in the above description, respectively, so as to implement the free falling of the sample to be measured at the first height of the specified height or the directional falling of the sample to be measured when the sample is released at the second height.

Specifically, the positioning element 213 is disposed on the fixing base 212, and when the control circuit controls the positioning element 213 to be powered on, the positioning element 213 generates an adsorption force to adsorb and fix the pickup portion 211 on the fixing base 212; when the control circuit controls the positioning element 213 to lose power, the positioning element 213 cancels the suction force, so as to separate the pickup portion 211 from the fixing base 212. There are various specific technical solutions for the sensor, such as a travel switch or a photoelectric sensor, which are not described herein again.

Further, referring to fig. 4, in this embodiment, the falling device 2 further includes a buffer 4 disposed on the base 1, the buffer 4 is located below the pickup portion 211 and is disposed corresponding to the pickup portion 211, the pickup portion 211 falls downward to avoid an accident, and the buffer 4 below the pickup portion 211 can play a role in protection.

The specific test steps of the drop test apparatus 100 are:

if the set detection mode is random falling, the six-axis robot randomly picks up one sample to be detected at the feeding station a and conveys the sample to the falling station b; after the six-axis robot finishes conveying the samples to be detected on the falling station b, another sample to be detected is randomly picked up to another falling station b at the feeding station a again. Then, after the falling device 2 receives the sample to be detected conveyed by the six-axis robot, the power output shaft of the servo motor rotates forward to drive the belt wheel 23 connected with the power output shaft to rotate forward, the electromagnetic attraction component is electrified, the electromagnetic attraction component attracts the pickup part 211, the electromagnetic attraction component arranged on the fixed seat 212 is driven by the synchronous belt 24, so that the pickup part 211 is driven by the electromagnetic attraction component to move upwards along the slide rail 22, and when the pickup part 211 is conveyed to a set first height, the servo motor stops rotating; then, the first driver 25 drives the two clamping arms 2112 to separate, and the sample to be tested is no longer clamped, so that the sample falls downward from the first height free fall, completing a complete random drop test.

If when the detection mode that sets for falls for the orientation, six robots are in material loading station a department picks up one at random the sample that awaits measuring, six robots are adjusting the angle in the transportation process, make the sample that awaits measuring adjusts to required angle that awaits measuring, will adjust the angle the sample that awaits measuring transports to fall station b, likewise, work as six robots accomplish to this fall and transport on the station b the sample that awaits measuring after, again material loading station a picks up another at random the sample that awaits measuring to another fall station b department. Then, repeating the above steps, and when the sample to be measured is conveyed to a set height by the pick-up portion 211 with a set angle, the servo motor stops rotating; then, the electromagnetic attraction piece loses power, the pickup portion 211 is no longer attracted, so as to clamp the sample to be tested and fall downwards, because in the process of falling downwards, the pickup portion 211 abuts against the slide rail 22, the slide rail 22 gives a certain supporting force to the main body piece 2111 of the pickup portion 211, the pickup portion 211 does not turn over randomly or falls at a set angle, in order to avoid that the test result is influenced by the simultaneous falling of the pickup portion 211 and the sample to be tested, when the pickup portion 211 falls to the set second height, it can be understood that the second height is lower than the first height, and in order to enable the sample to be tested to keep the set angle as much as possible, the second height is arranged close to the ground, at this time, at the second height, the two clamping arms 2112 of the pickup portion 211 are released, and the sample to be tested collides with the ground at a set angle to complete one-time complete directional drop test.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention, which are made by using the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
