Description

Technical Field

[0001] The present invention relates to the technical field of motor core detection, and in particular to an automatic grasping and detecting device. Background Art

[0002] The fixed part of the motor is called the stator, on which pairs of DC-excited stationary main magnetic poles are installed; the rotating part, the rotor, is called the iron core, on which the armature winding is installed. Usually, the iron core is a cylindrical structure formed by stacking several silicon steel sheets with the same cross-sectional shape, and there are several through slots on the inner wall of the iron core for installing the armature winding.

[0003] In the production of motor cores, various tests need to be carried out on the finished motor cores. During the test, the motor cores need to be grabbed by a robotic arm to the specified position. Generally, multiple motor cores are placed in batches on the core placement plate and transported to the test area. Then the motor cores on the core placement plate are grabbed by the robotic arm to the specified position. However, the mechanical claws on the robotic arm are generally fixed, or need to be manually disassembled and replaced. In the process of grabbing and testing the motor core, in addition to using the pneumatic triangular claw to grab the motor core, the core placement plate where the motor core is placed needs to be transferred. However, the pneumatic triangular claw cannot grab the core placement plate. Therefore, two different robotic arms usually need to be set up, but this method requires an increase in the investment cost of the robotic arm. Summary of the Invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] An automatic grasping and detecting device includes a rotating robotic arm 1. The robotic arm 1 adopts the robotic arm 1 used in the industry in the prior art and can rotate freely 360 degrees. The grasping end of the robotic arm 1 is provided with a connecting seat 47. A sensor 9 is provided on one side of the connecting seat 47. The sensor 9 adopts the existing technology and is used to sense the position of the motor core to be grasped. The robotic arm 1 is surrounded by a core frame, a detection frame and a gripper frame 7.

The pneumatic triangular claw 8 adopts the existing technology. The pneumatic triangular claw 8 is used to grab the motor core, and the vacuum adsorption plate 10 is used to grab the core placement plate 2. The upper ends of the pneumatic triangular claw 8 and the vacuum adsorption plate 10 are provided with a connection structure that can be detachably connected to the connecting seat 47, which facilitates the replacement of the connecting seat 47 between the pneumatic triangular claw 8 and the vacuum adsorption plate 10.

[0029] When it is necessary to grab the motor core, the robot arm 1 rotates, and the connecting seat 47 is connected to the pneumatic triangular claw 8 through the connecting mechanism. The pneumatic triangular claw 8 grabs the motor core from the core placement plate 2 and takes it to the detection device for detection, or places the motor core to other required positions; the connecting seat 47 is connected to the vacuum adsorption plate 10 through the connecting structure, and the core placement plate 2 can be grabbed by vacuum adsorption for transfer. In this way, only one robot arm 1 is needed, and the purpose of grabbing the motor core and the core placement plate 2 can be achieved by replacing the gripper, which reduces the setting of the robot arm 1.

[0030] The preferred technical solution is that the connecting structure includes a first connecting head 14 fixedly set on the pneumatic triangular claw 8 and the upper end of the vacuum adsorption plate 10, the upper end surface of the first connecting head 14 is smoothly and flatly set, and a positioning hole 15 is provided in the center of the upper end surface of the first connecting head 14, and the connecting seat 47 includes a mounting seat fixedly connected to the robotic arm 1, and a positioning column matching the positioning hole 15 is provided in the center of the mounting seat, and a plurality of first vacuum adsorption holes are provided around the positioning column on the mounting seat, and the plurality of first vacuum adsorption holes correspond to the upper end surface of the connecting head, and a first vacuum tube connected to the first vacuum adsorption hole is provided on the side wall of the mounting seat, and the first vacuum tube is used to connect to an external vacuum generator.

In this way, it can be quickly connected and disassembled, and is convenient for replacement at any time.

[0032] The preferred technical solution is that the vacuum adsorption plate 10 includes a substrate 13, and the lower surface array of the substrate 13 is provided with a plurality of rubber covers 16, and the connecting structure is provided on the upper surface of the substrate 13, and the upper surface of the substrate 13 is provided with a second connecting head 17, and the second connecting head 17 is provided with a slot 24, and the inner wall of the second connecting head 17 is provided with a vacuum cavity, and the side wall of the second connecting head 17 is provided with a first connecting tube 23 connected to the vacuum cavity, and the first connecting tube 23 is connected one by one with the plurality of rubber covers 16 through a plurality of second connecting tubes 26, and the connecting seat 47 is provided with a plug matching the slot 24, and the plug is provided with a second vacuum tube, and after the plug is inserted into the slot 24, the second vacuum tube is connected to the vacuum cavity, and the second vacuum tube is connected to an external vacuum generator.

[0033] When the vacuum adsorption plate 10 grabs the iron core placement plate 2, several rubber covers 16 are pressed tightly against the substrate 13 of the iron core placement plate 2, and then negative pressure is generated through an external vacuum generator. The rubber cover 16 is made to have negative pressure through the second vacuum tube, vacuum chamber, first connecting tube 23 and second connecting tube 26, thereby adsorbing the iron core placement plate 2. The flexible rubber cover 16 can ensure easier sealing contact with the substrate 13 and is not easy to damage the surface of the substrate 13.

[0034] The preferred technical solution is that a plurality of cannulas 25 connected to the vacuum chamber are protruding from the slot 24, and the end face of the plug inserted into one end of the slot 24 has a plurality of sockets matching the cannulas 25, and the plurality of cannulas 25 correspond one-to-one to the plurality of sockets, and the plurality of sockets are connected to the second vacuum tube.

[0035] When the robot arm 1 grabs the vacuum adsorption plate 10, the plug is inserted into the slot 24, and the multiple inserts 25 are inserted into the multiple holes one by one. In this way, the negative pressure chamber and the second vacuum tube are connected. This structure can improve the sealing and avoid pressure release.

[0036] The preferred technical solution is that the upper end of the placement rack 12 is provided with two first support columns 18 and two second support columns 19, the two first support columns 18 are arranged at intervals, and the two second support columns 19 are arranged at intervals, the midpoint of the line connecting the two first support columns 18 coincides with the midpoint of the line connecting the two second support columns 19, and the line connecting the two first support columns 18 intersects the line connecting the two second support columns 19 vertically, the substrate 13 is supported on the upper ends of the two first support columns 18 and the two second support columns 19, the intersection of the line connecting the two first support columns 18 and the line connecting the two second support columns 19 is located below the center of the substrate 13, the upper end of the first support column 18 is protruded with a limit column 20, the size of the limit column 20 is smaller than the size of the first support column 18, and the substrate 13 has two limit holes 27 that match the two limit columns 20 respectively, and the limit column 20 is inserted into the limit hole 27.

[0037] The vacuum adsorption plate 10 is supported by the two first support columns 18 and the second support columns 19 , and the limiting columns 20 are inserted into the limiting holes 27 to prevent the vacuum adsorption plate 10 from sliding and falling.

[0038] The preferred technical solution is that three support rods 22 are extended outward from the upper side wall of the pneumatic triangular claw 8, and the angle between the three support rods 22 is 120°. The placement rack 12 is provided with three support vertical plates 21, and the three support vertical plates 21 correspond to the three support rods 22 respectively. The upper ends of the support vertical plates 21 have card slots matching the support rods 22, and the three support rods 22 are respectively inserted into the three card slots to support the pneumatic triangular claw 8. The outer wall of the pneumatic triangular claw 8 has a third vacuum tube connected to the cylinder in the pneumatic triangular claw 8, and the third vacuum tube is used to connect to an external vacuum generator.

[0039] The pneumatic triangular claw 8 is supported by three supporting uprights 21 and is locked in a slot by a supporting rod 22 to prevent the pneumatic triangular claw 8 from sliding and falling.

[0040] The preferred technical solution is that the detection device includes a size detection device, an end face detection device and a side wall detection device. The size detection device is used to detect the size of the motor core. The size detection device includes a cylindrical bracket 5 arranged horizontally on the detection table 4. One end of the cylindrical bracket 5 is connected to the visual detection system 6. The motor core is inserted into the cylindrical bracket 5 horizontally from the other end of the cylindrical bracket 5. The visual detection system 6 detects the external size of the motor core from one end of the motor core.

[0041] A mounting bracket 28 is fixedly provided in the detection table 4, and a vertically movable lifting plate 29 is provided in the mounting bracket 28. A vertically arranged connecting rod is fixedly provided at the lower end center of the lifting plate 29. A lifting cylinder 44 is installed at the lower end of the mounting bracket 28. The telescopic rod of the lifting cylinder 44 is connected to the lower end of the connecting rod by a rotating connector. A plurality of detection cleaning rods 30 are vertically provided on the lifting plate 29. The cross-sectional shape of the detection cleaning rods 30 matches the through-grooves of the motor core. A plurality of detection cleaning rods 30 are arranged around a circle and correspond one to one with the plurality of through-grooves on the motor core. A plurality of detection cleaning rods 30 are provided above the mounting bracket 28. A supporting plate 35 is mounted on the test table 4. A first rotating disk 38 is rotatably mounted on the supporting plate 35. The first rotating disk 38 is driven by a rotation drive mechanism.

[0042] The motor core is transferred to the placement slot 43 by the robot arm 1, and the motor core is rotated so that the plurality of through slots on the motor core are aligned. The lifting cylinder 44 drives the lifting plate 29 to rise, driving a plurality of detection cleaning rods 30 to rise and insert into and pass through the through slots. Since the motor core is composed of a plurality of stacked silicon steel sheets, if any silicon steel sheet is not completely overlapped when stacked and deviates, it will form an obstruction in the through slot.

[0044] The lower end of the pull rod of the first displacement sensor 40 descends and rests on the upper end face of the motor core, and one end of the second displacement sensor 41 rests on the side wall of the motor core. The first rotating disk 38 drives the motor core to rotate, and the pull rod of the first displacement sensor 40 slides on the upper end face of the motor core as the motor core rotates. During this process, whether the first displacement sensor 40 detects a displacement change is used to determine whether the height of the end face of the motor core is consistent in the circumferential direction. The pull rod of the second displacement sensor 41 slides on the side wall of the motor core as the motor core rotates. During this process, whether the second displacement sensor 41 detects a displacement change is used to determine whether the thickness of the side wall of the motor core is consistent in the circumferential direction.

The first displacement sensor 40 is installed on the movable frame 46.

[0046] The cylinder drives the movable frame 46 to move, thereby driving the first displacement sensor 40 to move. When placing or removing the motor core, the first displacement sensor 40 moves away from the placement slot 43 to avoid obstruction.

[0047] According to the preferred technical solution, the supporting plate 35 is slidably mounted on the inspection platform 4 through two guide rails 34.
