Technical Field

[0001] This utility model belongs to the field of motor production equipment, and relates to quick disassembly and assembly devices, particularly to an automatic material handling device for the production of automotive generator end caps. Background Technology

[0002] An end cover is a rear cover installed behind the housing of a motor or other machine. It is commonly known as an "end cover". A quick disassembly and assembly device is required when processing end covers.

[0003] For example, an automatic end cap feeding device disclosed in CN207580866U includes a vibrating feeding plate for feeding end caps and a material transfer mechanism. The material transfer mechanism includes a mounting plate; the mounting plate is equipped with an end cap positioning block that receives material from the discharge port of the vibrating feeding plate, an end cap distributing swing arm, and a stepper motor that drives the end cap distributing swing arm; a distributing vacuum suction cup is installed on the end cap distributing swing arm; a sensor for sensing end caps is installed on the end cap positioning block; after the sensor senses an end cap, it sends a signal to control the stepper motor to complete one material transfer action; after the vibrating feeding plate feeds the end caps, the end cap positioning block receives the material, and after the sensor senses an end cap, it sends a signal to control the stepper motor to drive the end cap distributing swing arm to rotate, and the distributing vacuum suction cup picks up the end cap and moves it out. The feeding and distributing speed is fast, which greatly improves production efficiency and saves labor.

[0004] The above structure uses a suction cup to pick up the end cap. However, since most end caps are irregularly shaped and have uneven textures on their surface, the suction cup may not be able to pick them up stably, which can lead to errors in picking up the end cap. Utility Model Content

[0005] This utility model provides an automatic material handling device for the production of automotive generator end caps, which can more stably grasp the end caps.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic material handling device for the production of automobile generator end caps, comprising a machine body, characterized in that a plurality of slide frames that can slide up and down are rotatably connected to the machine body, a plurality of main rods are rotatably connected to each slide frame, two fixed rods are fixedly connected to the bottom end of each main rod, and a claw is rotatably connected to the end of each fixed rod away from the main rod, and a magnetic sheet is fixedly connected to the opposite surface of each of the two claws. When the end cap is grasped, the claw abuts against the side wall of the end cap and the magnetic sheet attracts the end cap.

[0007] A further preferred embodiment of this invention is that the claw is hinged to the fixed rod via a pin.

[0008] A further preferred technical solution of this utility model is: a torsion spring for driving the jaws to rotate is sleeved on the pin shaft, and the torsion spring deforms when the distance between the two jaws decreases.

[0009] A further preferred technical solution of this utility model is as follows: an installation groove is provided in the main rod, and a pull rod is rotatably connected in the installation groove. The pull rod and the claw are connected by a pull rope. When the pull rod rotates, the pull rope wraps around the pull rod and the claw rotates inward toward the fixed rod.

[0010] A further preferred embodiment of this utility model is as follows: a motor is fixedly connected to the slide, and pulleys are fixedly connected to the output end of the motor and the top end of the pull rod, with the two pulleys connected by a transmission belt.

[0011] A further preferred embodiment of this utility model is: a groove is provided on the bottom surface of the fixing rod, and the pull rope slides within the groove.

[0012] A further preferred technical solution of this utility model is as follows: a sliding groove is provided on the bottom surface of the main rod, and a sensor connected to the pull rod is slidably connected in the sliding groove. When the claw needs to grab the end cap, the sensor abuts against the end cap, the sensor slides into the sliding groove and sends a signal to the pull rod to drive the pull rod to rotate.

[0013] A further preferred embodiment of this utility model is that a plurality of springs for pushing the sensing element to slide are fixedly connected between the sliding groove and the sensing element.

[0014] Compared with the prior art, this utility model includes a body with several main rods rotatably connected to it. Two fixed rods are fixedly connected to the bottom of the main rods. A claw is rotatably connected to the end of the fixed rod away from the main rod. Magnetic plates are fixedly connected to the opposite surfaces of the two claws. When gripping an end cap, the claws abut against the side wall of the end cap, and the magnetic plates attract the end cap. Therefore, when gripping an end cap, rotating the claws can firmly grip the end cap on the main rod, while the magnetic plates attract the end cap, preventing it from slipping. This further improves the stability of the claws gripping the end cap. Furthermore, this design is applicable to end caps of different shapes, has a wide range of applications, provides a stable grip, and is easy to use. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0020] Figures 1-6 As shown, an automatic material handling device for producing automobile generator end caps includes a body 8, on which several slides 1 are rotatably connected. The slides 1 can slide up and down to facilitate clamping the end caps. Several main rods 2 are fixedly connected to each slide 1. When the end cap is clamped on the main rod 2, the slide 1 rotates to move the end cap to the next processing point. Two fixing rods 3 are fixedly connected to the bottom of the main rod 2. A chuck 11 is rotatably connected to the end of the fixing rod 3 away from the main rod 2.

[0021] Figures 1-6 As shown, when it is necessary to clamp the end cap, slide the slide 1 so that the end cap is located between the two jaws 11. Then rotate the jaws 11 to clamp the end cap. Slide the slide 1 further upward to clamp the end cap. Then rotate the slide 1 to move the end cap to the next processing point. Slide the slide 1 downward and release the jaws 11 to place the end cap on the next processing point for easy processing. This design uses the jaws 11 to clamp the end cap, which can avoid the problem of uneven end cap surface affecting the clamping effect. At the same time, the jaws 11 can clamp end caps of different shapes and sizes, effectively improving the applicability of clamping end caps.

[0022] Figures 1-6 As shown, magnetic sheets 12 are fixedly connected to the opposite surfaces of the two claws 11. When gripping the end cap, the claws 11 abut against the side wall of the end cap and the magnetic sheets 12 are attracted to the end cap, which makes the claws 11 grip the end cap more firmly and effectively improves the gripping ability of the claws 11.

[0023] Figures 1-6 As shown, the claw 11 is hinged to the fixed rod 3 via a pin 15. A torsion spring 16 is sleeved on the pin 15 to drive the claw 11 to rotate. When the distance between the two claws 11 decreases, the torsion spring 16 deforms. The pin 15 can position the rotation of the claw 11 to prevent the claw 11 from shifting during rotation. When the claw 11 rotates, the torsion spring 16 deforms. After the action of gripping the end cap is completed, the deformed torsion spring 16 can drive the claw 11 to reset, which is convenient for the next gripping and improves the ease of use.

[0024] Figures 1-6 As shown, the main rod 2 has an installation groove, and a pull rod 13 is rotatably connected in the installation groove. The pull rod 13 is connected to the claw 11 by a pull rope 14. When the pull rod 13 rotates, the pull rope 14 is stretched and wrapped around the pull rod 13, and the claw 11 rotates into the fixed rod 3. The bottom surface of the fixed rod 3 has a groove 9, and the pull rope 14 slides in the groove 9. This design serves to hide the pull rope 14.

[0025] Figures 1-6 As shown, when it is necessary to grab the end cap, slide the slide 1 downwards. At this time, the end cap is located between the two claws 11. Then rotate the pull rod 13. As the pull rod 13 rotates, the pull rope 14 gradually wraps around the pull rod 13 and drives the two claws 11 to rotate towards the end cap until the claws 11 clamp the end cap. At this time, the end cap is attracted to the magnetic sheet 12. Slide the slide 1 upwards to clamp the end cap and rotate the slide 1 towards the next processing point. Figures 1-6 As shown, the above structure achieves the rotation of the claw 11 through the cooperation of the pull rod 13 and the pull rope 14, thereby completing the action of clamping the end cap. The operation is convenient, quick and easy to implement.

[0026] Figures 1-6 As shown, a motor 6 is fixedly connected to the slide 1. Pulleys 4 are fixedly connected to the output end of the motor 6 and the top end of the pull rod 13. The two pulleys 4 are connected by a transmission belt 5. When the pull rod 13 needs to rotate, the motor 6 is started. At this time, the output end of the motor 6 drives the pulley 4 fixedly connected to it to rotate. The transmission belt 5 slides as the pulley 4 on the output end of the motor 6 rotates, and at the same time, it drives the pulley 4 on the pull rod 13 to rotate, thereby driving the pull rod 13 to rotate. This design achieves the rotation of the pull rod 13.

[0027] Figures 1-6As shown, a sliding groove is provided on the bottom surface of the main rod 2. A sensor 7 connected to the pull rod 13 is slidably connected in the sliding groove. When the claw 11 needs to grab the end cap, the sensor 7 abuts against the end cap, slides into the sliding groove, and sends a signal to the motor 6 to drive the pull rod 13 to rotate.

[0028] Figures 1-6 As shown, when clamping the end cap, the main rod 2 is moved above the end cap, and the slide 1 continues to slide so that the sensor 7 comes into contact with the surface of the end cap. At this time, the sensor 7 sends a signal to the motor 6, and the motor 6 starts, driving the pull rod 13 to rotate, so that the claw 11 clamps the end cap. In this design, the sensor 7 plays the role of sensing the end cap and controlling the motor 6, while the slide groove can prevent damage to the sensor 7 caused by the continuous downward pressure of the slide 1 when clamping end caps of different sizes.

[0029] Figures 1-6 As shown, a number of springs 10 are fixedly connected between the slide and the sensing element 7 to push the sensing element 7 to slide. When the end cap is clamped and the sensing element 7 slides into the slide, the sensing element 7 is pushed out and reset, which facilitates the clamping of the end cap next time.
