Description

Technical Field

[0001] The invention relates to the technical field of motor production equipment, and in particular to an automatic feeding device for a motor housing. Background Art

[0002] The motor housing is an indispensable component of motor equipment. The motor housing wraps around the outside of the motor to prevent dust, dirt, moisture and other impurities from entering the motor, avoiding possible short circuits, corrosion or damage, and ensuring that the motor can maintain its performance stability and reliability in various harsh environments. The motor housing provides strong support for the various components inside the motor, ensuring that they will not be displaced or deformed when running at high speed or under load.

[0003] When assembling the motor, the manipulator grabs the motor housing in the tray for loading. In order to save costs, the tray is generally made of plastic. After long-term use, the tray is prone to deformation, which affects the placement of the motor housing in the tray, and then affects the gripping accuracy of the motor housing by the manipulator, which easily leads to deformation of the motor housing and the manipulator, affecting the normal production of the motor. Moreover, a small number of motor housings themselves may be defective due to transportation and other reasons, affecting the normal production of the motor. Therefore, if the deformation of the motor housing or the tray can be discovered in time when the motor housing is loaded, the maintenance frequency of the manipulator can be reduced, and the yield rate of the motor installation can be greatly improved. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the deficiency in the prior art that the deformation of the motor housing or the material tray cannot be discovered in time when the motor housing is loaded, the present invention provides an automatic loading device for the motor housing.

[0006] There are several motor housings to be processed in the material tray, and the conveyor belt is used to transport the material tray; when the conveyor belt transports the material tray to the end of the conveyor belt, it is limited by the limit assembly to make its position unique; the first driving assembly is used to drive the adjustment frame to move along the width direction of the conveyor belt, so that the position of the pneumatic clamp corresponds to the position of a row of accommodating cavities in the width direction of the material tray, which is convenient for the pneumatic clamp to descend under the drive of the first cylinder and take the motor housing out of the accommodating cavity; the second driving assembly is used to drive the slide to slide along the length direction of the conveyor belt, so that the pneumatic clamp can place each motor housing on the loading platform; the material tray is a plastic part, and the reference plate of the material tray cooperates with the limit assembly to correct the position of the material tray. Long-term extrusion of the limit assembly will cause local deformation of the reference plate. If the reference plate is deformed, the correction position of the tray will be inaccurate, and the center of the motor housing in the tray will be offset, and it will not be on the same vertical line as the center of the pneumatic clamp. A spring is set between the pneumatic clamp and the slide. After the pneumatic clamp clamps the motor housing, the spring bends, the pneumatic clamp will be center offset, and the infrared receiver will not receive the signal from the infrared transmitter. When the infrared receiver cannot receive the signal from the infrared transmitter, it sends a signal to the controller. After the controller sends an alarm, the staff checks whether the motor housing is deformed or the tray is deformed. If the tray is deformed, the relevant reference plate is replaced.

[0007] Furthermore, in order to correct the position of the material tray so that the position of the motor housing in the material tray corresponds to the position of the pneumatic clamping claw, the limit assembly includes a baffle, a limit claw and two clamping plates, the baffle is arranged at the end of the conveyor belt, the baffle is provided with a second cylinder for driving the baffle to rise and fall, the limit claw is arranged above the conveyor belt, the distance between the baffle and the limit claw is equal to the width of the frame plus the width of a reference plate, the limit claw is provided with a third cylinder for driving the limit claw to move closer to or away from the conveyor belt in the vertical direction, the two clamping plates are arranged on both sides of the conveyor belt, the two clamping plates are arranged between the baffle and the limit claw, the two clamping plates are provided with a fourth cylinder for driving the two clamping plates to move closer to or away from the conveyor belt, and the distance between the two clamping plates when extended is equal to the length of the material tray.

[0008] When the material tray is transported to the end of the conveyor belt, the conveyor belt pushes the material tray onto the baffle, and the reference plate close to the baffle cooperates with the baffle to initially limit the material tray, and then the two fourth cylinders push the two clamping plates to clamp the material tray, so that the material tray is in the middle position in the width direction of the conveyor belt; after the material tray is fixed, the third cylinder drives the limit claw to drop, and the limit claw and the outer wall of the frame are matched with each other, mainly to prevent the center of the motor housing in the material tray and the center of the pneumatic clamp from being on the same vertical line, and the pneumatic clamp supports the inner wall of the motor housing to drive the position of the material tray; when the motor housing in the working position material tray is loaded with materials, the second cylinder drives the baffle to drop, and the empty material tray continues to be transported downward with the conveyor belt. At this time, the limit claw can also block the subsequent material trays from entering the working position.

[0009] Furthermore, in order to drive the adjustment frame to move along the width direction of the conveyor belt, the first driving assembly includes a first guide rail, a second guide rail and a transmission rack, the first guide rail and the transmission rack are arranged at the upper end of the bracket along the width direction of the conveyor belt, the second guide rail is arranged on the side wall of the bracket along the width direction of the conveyor belt, the adjustment frame is provided with a slider that cooperates with the first guide rail and the second guide rail, the adjustment frame is provided with a servo motor, and the output end of the servo motor is provided with a gear that meshes with the transmission rack.

[0012] Furthermore, the loading platform is provided with a plurality of limiting grooves which cooperate with the motor housing.

[0013] The beneficial effects of the present invention are as follows: the present invention provides an automatic feeding device for motor casings, which adopts a spring arranged on the pneumatic clamp so that the position of the pneumatic clamp can be offset to a certain extent.

[0023] Working process: The conveyor belt 2 transports the material tray 3 toward the pneumatic clamp 11, and the second cylinder 18 drives the baffle 15 to rise. When the material tray 3 is transported to the end of the conveyor belt 2, the conveyor belt 2 pushes the material tray 3 onto the baffle 15, and the baffle 15 cooperates with the reference plate 303 to limit the material tray 3, and then the two fourth cylinders 20 push the two clamping plates 17 to clamp the reference plates 303 on both sides of the material tray 3 to fix the position of the material tray 3; after the material tray 3 is fixed, the third cylinder 19 drives the limit claw 16 to descend, and the limit claw 16 cooperates with the gap between the outer wall of the frame 301 and prevents subsequent material trays 3 from entering the working position.

[0024] The adjusting frame 7 is slidably connected with the bracket 6 through the first guide rail 21 and the second guide rail 22, and the gear at the output end of the servo motor 25 cooperates with the transmission rack 23 to drive the adjusting frame 7 to move along the width direction of the conveyor belt 2, so that the position of the pneumatic clamp 11 corresponds to the position of a row of accommodating cavities 302 in the width direction of the material tray 3, which facilitates the pneumatic clamp 11 to descend under the drive of the first cylinder 9; when the pneumatic clamp 11 descends to the inside of the motor housing 4, the pneumatic clamp 11 is propped up. If the pneumatic clamp 11 and the motor housing 4 are on the same vertical line, the infrared receiver 14 can receive the infrared transmitter 13 signal, the first cylinder 9 can shrink normally to grab the motor housing 4; if the pneumatic clamp 11 and the motor housing 4 are not on the same vertical line, after the pneumatic clamp 11 clamps the motor housing 4, the spring 12 bends, and the pneumatic clamp 11 will be offset from the center, then the infrared receiver 14 cannot receive the signal from the infrared transmitter 13. When the infrared receiver 14 cannot receive the signal from the infrared transmitter 13, it sends a signal to the controller. After the controller sends out an alarm, the staff checks whether the motor housing 4 or the material tray 3 is deformed. If the material tray 3 is deformed, the relevant reference plate 303 is replaced.

[0025] After the three pneumatic clamps 11 grab a row of three motor housings 4 in the material tray 3, the first cylinder 9 contracts to grab the motor housings 4, the servo motor 25 starts, drives the adjustment frame 7 to move the pneumatic clamps 11 to the top of the loading platform 5, and the first cylinder 9 cooperates with the driving motor to place the motor housings 4 one by one into the limiting grooves 501 on the loading platform 5.

[0026] After one group of motor housings 4 are loaded, the servo motor 25 drives the pneumatic clamp 11 to move to the top of the next row of motor housings 4 on the tray 3 to prepare for loading the next group of motor housings 4 .

[0027] After all the motor housings 4 in the tray 3 are loaded, the two fourth cylinders 20 contract, the two clamping plates 17 release the tray 3, the output end of the second cylinder 18 contracts, the baffle 15 and the guide plate 28 drop in position, and the empty tray 3 continues to be transported along the conveyor belt 2, and slides onto the return plate 27 through the guide plate 28. At this time, the limit claw 16 can also block the subsequent tray 3 from entering the working position. After the empty tray 3 is conveyed to the return plate 27, the output end of the second cylinder 18 extends out, the baffle 15 and the guide plate 28 rise, and the empty tray 3 slides down along the return plate 27. Then the output end of the third cylinder 19 contracts, and the next tray 3 equipped with a motor housing 4 enters the working position, ready for the next round of loading.
