In view of the above, the present invention also provides an automatic rotary drop test machine. FIGS. 1 to 15 are specific embodiments of the automatic rotary drop test machine provided by the present invention.

The automatic rotary drop test machine 100 provided by the present invention is suitable for testing various types of products 200 to be tested, and is especially suitable for testing spherical products 200 to be tested. For a unified description, the following takes the spherical product 200 to be tested as an example to describe the automatic rotary drop test machine 100.

1 to 3, the automatic rotary drop test machine 100 includes a base 1, a rotating mechanism 2, a transfer mechanism 3, and a pickup mechanism 4. The base 1 has a rotating station 11 and a drop station 12 arranged at intervals; The rotating mechanism 2 is set on the machine base 1 to rotate the product 200 to be tested at the rotating station 11 to a desired angle; the transfer mechanism 3 is set on the machine base 1 to transfer the product 200 to be tested from the rotating station 11 To the drop station 12; the pick-up mechanism 4 is mounted on the machine base 1 so as to be lifted and lowered to pick up the product 200 to be tested from the drop station 12 and release it after being lifted to a desired height.

In the technical solution provided by the present invention, after the rotating mechanism 2 rotates the product 200 to be tested to a required angle, the transfer mechanism 3 transfers the product 200 to be tested to the drop station 12 for the picking mechanism 4 to pick up and lift it to the required height. Release, the test process is automatically completed by the rotating mechanism 2, the transfer mechanism 3, and the picking mechanism 4, without relying on manual operation, and has the advantages of accurate drop point and high efficiency, which helps to optimize the test effect.

It is understandable that the base 1 is used to connect and support the rotating mechanism 2, the transfer mechanism 3, and the pick-up mechanism 4, and may be embodied in a box shape or a rack shape, etc.; the base 1 may It is a monolithic structure, which can also be composed of a combination of multiple split components. The specific expressions such as the shape and size of each split component are adapted to the rotating mechanism 2, the transfer mechanism 3, and the pickup mechanism 4 at the corresponding position; more The separate components may be integrally formed and arranged, or they may be connected into one body by means such as welding, screw connection, or snap-fitting.

The rotating station 11 and the drop station 12 are arranged at intervals, and the rotating mechanism 2 is arranged at the rotating station 11, and the picking mechanism 4 is arranged at the drop station 12, so that the angle adjustment operation of the product under test 200 and the drop test operation are mutually exclusive The interference helps the angle adjustment operation of the automatic rotary drop test machine 100 and the drop test operation to be performed at the same time, thereby improving the test efficiency of the automatic rotary drop test machine 100. The transfer mechanism 3 transfers the product under test 200 from the rotating station 11 to the drop station 12 to realize the accurate connection between the angle adjustment operation and the drop test operation of the same product under test 200, which helps to eliminate the easy operation errors during manual operations. The problem.

Further, referring to FIGS. 4 and 5, in one embodiment, the rotating mechanism 2 includes two clamping parts 21, a first driver 22, and a second driver 23, wherein the two clamping parts 21 are separately provided in the rotating work The two opposite sides of the position 11 are movably arranged along the clamping direction close to and away from each other, and the clamping part 21 is rotatable along the axis of the clamping direction; the first driver 22 is used to drive the two clamping parts 21 along the clamping direction. The second driver 23 is used to drive the clamping portion 21 to rotate along the axis of the clamping direction, so as to drive the product 200 to be tested to rotate to a desired angle through the clamping portion 21. The first driver 22 can drive and connect one of the two clamping parts 21, and then control the clamping part 21 to approach the other clamping part 21, so as to realize the detection of the product 200 to be tested in the middle of the two clamping parts 21 Clamping fixed or unfixed; or, the first driver 22 may be provided with two corresponding to the two clamping parts 21, respectively driving the two clamping parts 21 to approach or move away from each other, so as to realize the alignment between the two clamping parts 21 The product 200 to be tested in the middle is clamped and fixed or unfixed. Among them, the first driver 22 may be a motor used in conjunction with a transmission component such as a lead screw, or may be directly constituted by, for example, a rodless cylinder alone. Similarly, the second driver 23 can drive to connect at least one of the two clamping parts 21. For example, the rotating mechanism 2 includes two bearing seats, and the two clamping parts 21 are respectively rotatably mounted on the two bearing seats via a rotating shaft. On; the second driver 23 is a servo motor, drivingly connected to one of the clamping parts 21, when the two clamping parts 21 clamp and fix the product under test 200, the product under test 200 realizes the connection of the two clamping parts 21, As a result, when the second driver 23 drives the clamping part 21 connected to it to rotate, the other clamping part 21 and the product to be tested 200 realize synchronous rotation.

It should be noted that the two clamping parts 21 in the rotating mechanism 2 are movably installed on the same installation platform of the machine base 1. At this time, the spherical product under test 200 is taken as an example, and the installation platform is taken as the reference plane. Optionally, the heights of the rotation axes of the two clamping parts 21 are equivalent, and the height of the rotation axes of the two clamping parts 21 is equivalent to the height of the sphere center of the spherical product 200 to be tested, so that when the two clamping parts 21 clamp When the product under test 200 is held fixed and rotated, the rotation of the product under test 200 can be roughly simulated, which helps to improve the accuracy of angle adjustment. Further, a frame may be provided around the rotation station 11 to restrict the spherical product 200 to be tested from rolling on the installation platform.

Next, in this embodiment, at least two rotating mechanisms 2 are provided, and the two clamping directions of the two rotating mechanisms 2 are arranged crosswise; taking the two rotating mechanisms 2 as an example, the two rotating mechanisms 2 The two clamping directions can be set approximately vertically, and the four clamping parts 21 of the two rotating mechanisms 2 are arranged at intervals along the circumference of the rotating station 11, which helps increase the angular adjustment range of the product 200 to be tested, thereby increasing The practicality of the automatic rotating drop test machine 100.

In actual operation, in order to distinguish, define two rotation mechanisms 2 including a first rotation mechanism and a second rotation mechanism. After the product 200 to be tested is placed on the rotation station 11, first operate the two clamps of the first rotation mechanism. The holding parts 21 are close to each other to clamp and fix the product 200 to be tested, and rotate around the clamping direction of the first rotating mechanism to a required first angle; then, the two holding parts 21 of the second rotating mechanism are operated to each other Close to clamp and fix the product 200 under test, the two clamping parts 21 of the first rotating mechanism are far away from each other and make way to avoid interference with the two clamping parts 21 of the second rotating mechanism, and then operate the second rotating mechanism 2 The two clamping parts 21 rotate around the clamping direction of the second rotating mechanism to the required second angle; finally, the first angle and the second angle are algorithmically compounded to obtain the product under test 200 in the space Angle adjustment on the top.

When the product 200 to be tested is spherical, the clamping surface 211 of the clamping portion 21 is set in a concave arc shape, which helps to expand the contact area between the clamping surface 211 and the outer wall surface of the product 200 to be tested. In addition, the rotation axis of the clamping portion 21 is aligned with the center of the sphere of the product 200 to be tested, thereby improving the accuracy of rotation adjustment.

The two pulleys are arranged at intervals along the extending direction of the first guide rail. The first timing belt 32 It is wound on two pulleys, and the base 31 is fixedly installed on a belt surface of the first timing belt 32. The third driver 33 is, for example, a servo motor, and the power output end of the servo motor is drivingly connected to one of the two pulleys. Specifically, when the power output shaft of the servo motor rotates forward, the pulley connected to it is driven to rotate forward, and the base 31 and the rotating mechanism 2 on the base 31 are driven to move from the rotation station 11 to the drop station through the first timing belt 32.

Among them, there may be multiple specific solutions for the connecting piece, for example, the connecting piece may be rotatably arranged. The screw connection parts are respectively threaded with the two threaded holes provided on the two splints, and the spiral directions of the two threaded holes are set in opposite directions. At this time, the fourth driver 43 can be a motor, and the forward and reverse rotation of the motor drives the screw. The positive and negative rotation of the connecting piece is realized so that the two splints are close to each other to pick up the product 200 to be tested, and the two splints are moved away from each other to release the product 200 to be tested; in addition, in one embodiment, the connecting piece may also be connected to the first The four drivers 43 are integrally arranged. At this time, the fourth driver 43 is, for example, a two-way air cylinder. Of course, the first pick-up part 41 may also have other structures, such as a manipulator, which will not be described in detail here. The setting of the second timing belt 42 is the same as that of the first timing belt 32, and the setting of the fifth driver 44 is the same as that of the third driver 33, and will not be repeated here.

At this time, the above-mentioned pickup mechanism 4 can be used for a free fall drop test of the product 200 to be tested. Specifically, when the transfer mechanism 3 moves the product 200 to be tested from the rotating station 11 to the drop station 12, the fifth driver 44 drives the first After the second timing belt 42 rotates forward and drives the first pick-up part 41 to move down to the drop station 12 in the vertical direction, the fourth driver 43 drives the first pick-up part 41 to pick up the product 200 to be tested; then, the fifth driver 44 After driving the second timing belt 42 to reverse, and driving the first pick-up part 41 to move up to the required height in the vertical direction, the fourth driver 43 drives the first pick-up part 41 to release the product under test 200, so that the product under test 200 is Free fall drop test at a specified height.

Specifically, for example, the electromagnetic attraction member 46 is arranged on the fixing seat 45. When the control circuit controls the electromagnetic attraction member 46 to be energized, the electromagnetic attraction member 46 generates an adsorption force to adsorb and fix the first pickup part 41 on the fixing seat 45. When the control circuit controls the electromagnetic attraction member 46 to lose power, the electromagnetic attraction member 46 cancels the adsorption force, and realizes the separation of the first picking portion 41 and the fixing seat 45. There are many specific technical solutions for the sensor, such as a travel switch or a photoelectric sensor, etc., which will not be repeated here.

At this time, the aforementioned pickup mechanism 4 can be used for the free fall drop test and the directional drop test of the product 200 to be tested. The free fall drop test can refer to the above, and will not be repeated here. The directional drop test process includes: when the transfer mechanism 3 is ready When the test product 200 moves from the rotating station 11 to the drop station 12, the fifth driver 44 drives the second timing belt 42 to rotate forward, and drives the fixing seat 45 and the first picking part 41 to move down in the vertical direction to the drop station. After bit 12, the fourth driver 43 drives the first pick-up part 41 to pick up the product 200; then, the fifth driver 44 drives the second timing belt 42 to reverse, and drives the fixing seat 45 and the first pick-up part 41 in the vertical direction After moving up to the required height, the control circuit controls the electromagnetic attraction member 46 to lose power, so that the first pick-up part 41 is separated from the fixing base 45 and slides down. When the first pick-up part 41 slides down to the position of the sensor After the sensor is triggered to send out the sensing signal, the control circuit controls the fourth driver 43 to drive the first pickup 41 to release the product under test 200 according to the received sensing signal, so as to realize the directional drop test of the product under test 200.
