Description

Technical Field

[0001] The present invention relates to the technical field of servo driver testing, in particular to a servo driver testing device and a testing method thereof. Background Art

[0002] A servo drive is a controller used to control a servo motor. Its function is similar to that of a frequency converter on an ordinary AC motor and is part of a servo system. It is mainly used in high-precision positioning systems to control servo motors in three ways: position, speed, and torque, to achieve high-precision transmission system positioning.

[0003] Servo drives are usually equipped with a variety of interfaces, such as USB interface, RS485 / 232 interface, analog interface, digital interface, Ethernet interface, encoder interface, etc. The existence of these interfaces enables the servo drive to better meet the needs of the automation control system and improve the overall performance and stability of the system. In order to ensure that the servo drive can be used normally, it is necessary to test each interface on the servo drive during the production process.

[0004] The current testing method is to manually insert the connector of the test mechanism into the corresponding interface to check whether the signal can be transmitted correctly. However, the manual testing method has the problems of low work efficiency and high labor intensity of workers, which cannot meet the needs of automatic transmission and automatic testing of servo drives, and convenient collection of servo drives with abnormal tests. To this end, we propose a servo drive test device and a test method to solve the above drawbacks. Summary of the invention

[0021] Optionally, the flipping mechanism includes a rotating shaft rotatably connected to the hollow tube, both ends of the rotating shaft extend outside the hollow tube, and a second driving component for driving the rotating shaft to rotate is installed on the vertical plate;

[0022] Linkage rods are fixedly connected at both ends of the rotating shaft, and a fixed shaft is fixedly connected between each linkage rod and the support plate; arc-shaped slide grooves are fixedly connected to the front and rear sides of the vertical plate, and each fixed shaft slides in the corresponding arc-shaped slide groove, and the central axis of each arc-shaped slide groove coincides with the central axis of the rotating shaft.

[0023] Optionally, the projection of the support plate on the vertical plane is L-shaped, and the projection of the support plate on the horizontal plane is comb-shaped.

[0024] Optionally, the centering clamping mechanism includes a fixed shell fixed to the bottom of the support plate, with two iron blocks sliding in the fixed shell, and a clamping plate that movably extends to the outside of the fixed shell is fixedly connected to the side of the two iron blocks away from each other, and each clamping plate is L-shaped and is respectively located on the front and rear sides of the support plate; an electromagnet is installed in the fixed shell between the two iron blocks, and a reset spring is connected between the electromagnet and each iron block.

[0025] The present invention also provides a servo drive testing method, comprising the following steps:

[0026] Step 1: In the initial state, the two groups of movable conveying rollers are close to each other, and each movable conveying roller rotates synchronously with each fixed conveying roller to convey the servo drive placed horizontally on the conveying surface;

[0027] Step 2: When the horizontally placed servo drive is transported to the two sets of movable conveying rollers, each movable conveying roller and each fixed conveying roller stops rotating; the two sets of movable conveying rollers are controlled to move away from each other by the opening and closing control mechanism until a through hole is formed;

[0028] Step 3: The lifting plate is driven upward by the lifting mechanism until the support plate contacts the horizontal servo driver, and then the horizontal servo driver is clamped by the centering clamping mechanism;

When the test result is normal, the lifting plate moves downward, and the flipping mechanism drives the support plate to rotate 90° counterclockwise, and then the centering clamping mechanism releases the servo driver to place the erected servo driver horizontally on two sets of movable conveying rollers; then each movable conveying roller and each fixed conveying roller rotate synchronously to convey the horizontally placed servo driver to the next test process;

[0033] Step 8. When the test result is abnormal, the lifting plate moves downward, driving the erected servo driver to move downward and pass through the opening; then the flipping mechanism drives the support plate to continue to rotate counterclockwise until it reaches the limit position, so that the erected servo driver tilts; finally, the centering clamping mechanism releases the tilted servo driver, and the servo driver with abnormal test result can be removed for collection.

[0034] Compared with the prior art, the present invention provides a servo drive test device and a test method thereof, which have the following beneficial effects:

[0035] 1. The present invention provides movable conveying rollers and fixed conveying rollers. Since the movable conveying rollers and the fixed conveying rollers cooperate with each other to form a continuous conveying surface, the servo drive can be automatically conveyed.

[0036] 2. The present invention provides an opening and closing control mechanism and a through port. When the servo drive needs to be transported, the opening and closing control mechanism is used to bring the two groups of movable conveying rollers closer to each other, thereby allowing a larger contact area between the movable conveying rollers and the servo drive, thereby ensuring the stability of transportation.

[0037] When the servo driver needs to be tested, the two groups of movable conveying rollers are moved away from each other to form a through opening through the opening and closing control mechanism, so that other components can pass through the through opening and drive the servo driver to move closer to the testing mechanism.

[0038] 3. The present invention arranges a lifting plate, a support plate, a flipping mechanism and a centering clamping mechanism. In a normal state, the lifting plate, the support plate, the flipping mechanism and the centering clamping mechanism are located below the conveying surface. When the servo driver needs to be tested, the lifting plate moves upward through the through opening, and the horizontally placed servo driver is erected through the cooperation of the support plate, the centering clamping mechanism and the flipping mechanism, so that the connector in the test mechanism can be inserted into the interface on the top surface of the erected servo driver, thereby automatically testing the servo driver.

[0039] When the test result is abnormal, the lifting plate moves downward, driving the erected servo driver to move downward through the through opening, and then tilting the erected servo driver, and finally releasing the tilted servo driver, the servo driver with the abnormal test result can be removed for collection.

[0040] 4. The present invention can automatically transport and test the servo drivers, and can conveniently collect the servo drivers with abnormal test results, thereby greatly improving the test speed of the servo drivers and reducing labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] Example 1: Please refer to Figures 1 to 10 , a test device for a servo drive, including a frame 1, which provides support and installation space for other components in the device. This embodiment also includes: two groups of movable conveying rollers 2, an opening and closing control mechanism 3, a plurality of fixed conveying rollers 4, a lifting plate 6, a support plate 8, a flipping mechanism 9, a centering clamping mechanism 10 and a testing mechanism 11, which are used for automatic conveying and automatic testing of the servo drive, and for facilitating the collection of servo drives with abnormal tests. Among them, the testing mechanism 11 includes a connecting seat and a tester, the connecting seat is L-shaped, the connecting seat is fixedly connected to the frame 1, the tester is arranged on the top wall of the connecting seat, and the connector of the tester is located on the lower surface of the top wall of the connecting seat, which is used to connect to the interface of the servo drive to test the function of the drive.

[0054] Two groups of movable conveying rollers 2 are distributed on the frame 1, and each group of movable conveying rollers 2 is composed of a number of movable conveying rollers 2 distributed at equal intervals. In this embodiment, a telescopic groove 12 is provided in the movable conveying roller 2, and a transmission shaft 13 that is movably inserted into the telescopic groove 12 is rotatably connected to the frame 1, and the movable conveying roller 2 can move along the axial direction of the transmission shaft 13, so as to adjust the spacing between the two groups of movable conveying rollers 2. A groove 14 is provided in the axial direction of the transmission shaft 13, and a convex rib 15 that is movably inserted into the groove 14 is fixedly connected to the movable conveying roller 2 in the axial direction. Through the cooperation of the groove 14 and the convex rib 15, the movable conveying roller 2 can only be telescopic along the axial direction of the transmission shaft 13, and cannot rotate relative to the transmission shaft 13. Therefore, when the transmission shaft 13 rotates, it can drive the movable conveying roller 2 in the contracted state or the expanded state to rotate synchronously.

[0055] The opening and closing control mechanism 3 is specifically introduced as follows:

[0056] The opening and closing control mechanism 3 is arranged on the frame 1, and is used to control the two groups of movable conveying rollers 2 to move away from and approach each other. Specifically, the opening and closing control mechanism 3 includes a bidirectional screw rod 301 that is rotatably connected to the frame 1 through a bearing and a shaft seat, and the bidirectional screw rod 301 is parallel to the movable conveying roller 2 and is located below the movable conveying roller 2. A first driving component 302 for driving the bidirectional screw rod 301 to rotate is arranged on the frame 1, and the first driving component 302 includes a servo motor installed on the frame 1, and the servo motor is connected to the bidirectional screw rod 301 through chain transmission, gear transmission or other transmission methods, so that the bidirectional screw rod 301 can be driven to rotate forward or reverse.

[0057] The two threaded sleeves 303 are respectively screwed together on the two threaded sections with different rotation directions of the bidirectional screw rod 301, and a connecting plate 304 is fixedly connected to the top of each threaded sleeve 303. When the bidirectional screw rod 301 rotates forward or reversely, the two connecting plates 304 can be driven to approach or move away from each other through the threaded sleeve 303. The two connecting plates 304 are respectively located below the two groups of movable conveying rollers 2, and a connecting sleeve 305 is rotatably connected to each movable conveying roller 2. The movable conveying roller 2 can rotate in the connecting sleeve 305, while the connecting sleeve 305 does not rotate. A connecting rod 306 is fixedly connected between each connecting sleeve 305 and the corresponding connecting plate 304. When the bidirectional screw rod 301 rotates forward or reversely, the two threaded sleeves 303 are made to approach or move away from each other, thereby driving the two connecting plates 304 to approach or move away from each other, and then driving the two groups of movable conveying rollers 2 to approach or move away from each other through the cooperation of the connecting rod 306 and the connecting sleeve 305.

[0058] It should be noted that an annular notch 16 is provided at the end of the movable conveying roller 2 close to the transmission shaft 13, and the connecting sleeve 305 is rotatably connected to the annular notch 16 so that the outer surface of the connecting sleeve 305 is lower than the outer surface of the movable conveying roller 2, so that the servo drive placed horizontally on the conveying surface is not easy to contact with the connecting sleeve 305, and thus is not easy to affect the normal conveying of the servo drive.

[0059] In this embodiment, a plurality of fixed conveying rollers 4 are mounted on the frame 1 and are evenly distributed on the front and rear sides of the two groups of movable conveying rollers 2. Each group of movable conveying rollers 2 and each fixed conveying roller 4 cooperate with each other to form a continuous conveying surface. It should be supplemented that each fixed conveying roller 4 and each movable conveying roller 2 can use chain drive, belt drive or gear drive to achieve power transmission, so that each fixed conveying roller 4 and each movable conveying roller 2 can run synchronously. This is a prior art and will not be repeated here. When the two groups of movable conveying rollers 2 move away from each other to the limit position, a through hole 5 is formed between the two groups of movable conveying rollers 2. The horizontal length of the servo drive placed horizontally on the conveying surface is greater than the horizontal length of the through hole 5, so the horizontal servo drive cannot pass through the through hole 5 normally.

[0060] A lifting mechanism 7 is connected between the lifting plate 6 and the frame 1. In this embodiment, the lifting plate 6 includes a vertical plate 601 arranged in the vertical direction, a horizontal plate 602 arranged in the horizontal direction is fixedly connected to the top of the vertical plate 601, a hollow tube 603 is fixedly connected to the side of the horizontal plate 602 away from the vertical plate 601, and the support plate 8 is hinged to the hollow tube 603. The lifting plate 6 adopts this structure, which is convenient for connection with other components in the equipment. The lifting mechanism 7 includes a cylinder installed on the frame 1, and the output end of the cylinder is fixedly connected to the vertical plate 601. When the cylinder is working, it can drive the vertical plate 601 to move upward or downward. A receiving groove 17 adapted to the cylinder is provided on the vertical plate 601. Under normal conditions, the cylinder shrinks into the receiving groove 17, thereby avoiding the excessive size of the equipment due to the extra space occupied.

[0061] It should be noted that the support plate 8 is hinged on the lifting plate 6, so the support plate 8 can rotate along the hinge. The projection of the support plate 8 on the vertical plane is L-shaped. When the support plate 8 is turned over, the bottom of the erected servo drive can be lifted by the L-shape. The projection of the support plate 8 on the horizontal plane is comb-shaped, which is convenient for passing through the gap between the movable conveying rollers 2.

[0062] The flipping mechanism 9 is specifically introduced as follows:

[0063] The flip mechanism 9 is arranged on the lifting plate 6, and is used to flip the support plate 8 along the hinge. Specifically, the flip mechanism 9 includes a rotating shaft 901 rotatably connected to the hollow tube 603, and both ends of the rotating shaft 901 extend outside the hollow tube 603. A second driving component 902 for driving the rotating shaft 901 to rotate is installed on the vertical plate 601. The structure of the second driving component 902 is the same as that of the first driving component 302, and is used to drive the rotating shaft 901 to rotate forward and reverse.

[0064] Linkage rods 903 are fixedly connected at both ends of the rotating shaft 901, and fixed shafts 904 are fixedly connected between each linkage rod 903 and the support plate 8; arc-shaped slide grooves 905 are fixedly connected to the front and rear sides of the vertical plate 601, and each fixed shaft 904 slides in the corresponding arc-shaped slide groove 905, and the central axis of each arc-shaped slide groove 905 coincides with the central axis of the rotating shaft 901. When the second driving component 902 drives the rotating shaft 901 to rotate, the linkage rod 903 can drive the fixed shaft 904 to slide in the arc-shaped slide groove 905; because the fixed shaft 904 is fixed to the support plate 8, it can drive the support plate 8 to flip, and then the servo drive placed horizontally on the support plate 8 can be flipped and erected, or the erected servo drive can be tilted.

[0065] The following is a detailed introduction to the centering clamping mechanism 10:

[0066] The centering clamping mechanism 10 is arranged on the support plate 8 and is used to clamp the servo drive. Specifically, the centering clamping mechanism 10 includes a fixed shell 1001 fixed to the bottom of the support plate 8, two iron blocks 1002 are slidably arranged in the fixed shell 1001, and a clamping plate 1003 that is movably extended to the outside of the fixed shell 1001 is fixedly connected to the side where the two iron blocks 1002 are far away from each other, and each clamping plate 1003 is L-shaped and is respectively located on the front and rear sides of the support plate 8; an electromagnet 1004 located between the two iron blocks 1002 is installed in the fixed shell 1001, and a reset spring 1005 is connected between the electromagnet 1004 and each iron block 1002. When the electromagnet 1004 is energized, a magnetic attraction is generated, thereby driving the two iron blocks 1002 to approach the electromagnet 1004, and then driving the two clamping plates 1003 to approach each other, so as to center and clamp the servo drive. When the electromagnet 1004 is powered off, each iron block 1002 is reset under the action of the reset spring 1005, so that the clamping plate 1003 can release the servo driver.

[0067] Embodiment 2: The present invention further proposes a servo drive test method, which is applicable to the servo drive test device in Embodiment 1, and comprises the following steps:

[0068] Step 1: In the initial state, the two groups of movable conveying rollers 2 are close to each other, and each movable conveying roller 2 rotates synchronously with each fixed conveying roller 4 to convey the servo drive placed horizontally on the conveying surface. Figure 1 As shown; at this time, the structure of the conveying surface is as follows Figure 5 As shown;

[0069] Step 2: When the horizontal servo drive is transported to the two sets of movable conveying rollers 2, each movable conveying roller 2 and each fixed conveying roller 4 stops rotating; the two sets of movable conveying rollers 2 are controlled to move away from each other by the opening and closing control mechanism 3 until a through hole 5 is formed. At this time, the structure of the conveying surface is as follows: Figure 6 As shown;

[0070] Since the horizontal length of the through opening 5 is smaller than the horizontal length of the servo drive placed horizontally, the servo drive can always be located on the conveying surface.

[0071] Step 3: Use the lifting mechanism 7 to drive the lifting plate 6 to move upward until the support plate 8 contacts the horizontal servo driver, and then clamp the horizontal servo driver through the centering clamping mechanism 10. Figure 2 As shown;

[0072] Step 4: The lifting plate 6 continues to move upward, and at the same time, the flip mechanism 9 drives the support plate 8 to rotate 90° clockwise to stand up the horizontally placed servo drive;

[0073] Step 5: The lifting plate 6 continues to move upward so that the connector in the test mechanism 11 is inserted into the interface on the top surface of the erected servo drive. Figure 3 As shown;

[0074] Step 6: Testing by the testing agency 11;

[0075] Step 7, when the test result is normal, the lifting plate 6 moves downward, and at the same time, the flip mechanism 9 drives the support plate 8 to rotate 90° counterclockwise, and then the centering clamping mechanism 10 releases the servo driver to place the erected servo driver horizontally on the two sets of movable conveying rollers 2; then each movable conveying roller 2 and each fixed conveying roller 4 rotate synchronously to convey the horizontally placed servo driver to the next test process;

[0076] Step 8: When the test result is abnormal, the lifting plate 6 moves downward, driving the erected servo driver to move downward through the opening 5; then the flip mechanism 9 drives the support plate 8 to continue to rotate counterclockwise until it reaches the limit position, so that the erected servo driver tilts, as shown in FIG. Figure 4 As shown; finally, the centering clamping mechanism 10 releases the tilted servo drive, and the servo drive with abnormal test results can be removed and collected.

[0077] It should be added that when the interface on the top surface of the servo driver in the horizontal state needs to be tested, the horizontal servo driver can be directly driven to move upward without turning the servo driver over. When the test result is abnormal, the horizontal servo driver is then stood up so that the servo driver with the abnormal test result can pass through the opening 5.

[0078] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0079] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
