Description

Technical Field

[0001] This utility model relates to the field of flat wire hair clips, specifically a flat wire hair clip insertion device. Background Technology

[0002] In the production of new energy vehicle motors, in order to improve the efficiency of motor products, flat wire hairpins have begun to be used instead of round electromagnetic wires. When the flat wire hairpins are assembled into the motor, they need to be inserted into the stator core of the motor in a specific way. In the actual production process, the flat wire hairpins are not directly inserted into the stator core, but need to be pre-inserted to form wire crowns, and then the whole assembly is transferred to the corresponding station for easy insertion into the stator core.

[0003] Flat wire hair clips are typically U-shaped, and most flat wire hair clips used in motors can be attracted by magnets. During the pre-insertion process of the flat wire hair clip to form the wire crown, a lifting assembly, a translating assembly, and a gripping assembly are used. After the gripping assembly grips and fixes the flat wire hair clip, the lifting assembly drives the gripping assembly to rise, the translating assembly drives the gripping assembly to move above the positioned workpiece, and the lifting assembly again drives the gripping assembly to descend, inserting the flat wire hair clip into the workpiece slot to complete the insertion action. However, existing gripping assemblies use gripping cylinders and two opposing grippers. The device consists of two gripping claws connected to the two piston rods of a gripping cylinder. When a flat wire clip needs to be gripped, the gripping cylinder drives the two gripping claws to approach each other and clamp the flat wire clip. However, the gripping claws can easily damage the flat wire clip when fixing it. Furthermore, after the flat wire clip is inserted, the gripping cylinder needs to be driven to operate the gripping claws to release the flat wire clip. This requires the two gripping claws to move horizontally, which inevitably causes the gripping claws to touch the already inserted flat wire clip, resulting in the inserted flat wire clip being deformed by force. Therefore, we propose a flat wire clip insertion device. Utility Model Content

[0004] The purpose of this utility model is to provide a flat wire hairpin insertion device, including a fixing box, a fixing groove inside the fixing box, the upper end of the fixing groove being U-shaped, an electromagnetic block one and a protective shell one fixedly connected to the outside of the fixing box, an electromagnetic block two and a protective shell two fixedly connected to the top of the fixing box, and an adjustment component fixedly connected to the top of the protective shell two. The angle of the fixed flat wire hairpin is adjusted by the adjustment component, the height is adjusted by the lifting component, and the horizontal position is adjusted by the horizontal displacement component.

[0005] Preferably, the first electromagnetic block is located inside the first protective shell, and the second electromagnetic block is located inside the second protective shell.

[0006] Preferably, the adjustment assembly includes an adjustment frame, on which a servo motor is fixedly mounted, and the drive end of the servo motor is fixedly connected to a protective shell.

[0007] Preferably, the lifting assembly includes a movable frame, on which a hydraulic cylinder is fixedly mounted, and the telescopic end of the hydraulic cylinder is fixedly connected to an adjusting frame.

[0008] Preferably, two sets of guide rods are fixedly connected to the top of the adjustment frame, and both sets of guide rods slide through the inside of the movable frame.

[0009] Preferably, the horizontal displacement assembly includes a displacement frame, on which a screw is rotatably mounted via bearings, and a second servo motor is fixedly mounted on the displacement frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses an electromagnetic block that generates strong magnetism when energized, which can firmly attract flat wire hair clips and avoid physical damage such as squeezing and scratches to the surface or structure of the flat wire hair clip when the mechanical claw clamps it. It is especially suitable for the fragile structure of U-shaped flat wire hair clips. This utility model uses an electromagnetic block that repels flat wire hair clips when energized, without the need for mechanical parts to move. This fundamentally avoids interference from the loosening action of the claw to the surrounding inserted workpieces and ensures the overall insertion accuracy of the wire crown.

[0014] 2. This utility model is equipped with electromagnetic block one (for adsorption) and electromagnetic block two (for auxiliary release). When the flat wire hair clip moves down to the workpiece slot, electromagnetic block one is de-energized and loses its magnetism. At the same time, electromagnetic block two generates a repulsive force by reversing the current direction (switching the N / S poles), pushing the flat wire hair clip to slide down from the fixed slot, ensuring that the flat wire hair clip is fully inserted into the workpiece slot, avoiding jamming problems caused by residual adsorption force, and improving the insertion success rate. Compared with mechanical clamping, electromagnetic control has a faster response speed (adsorption / release can be achieved by turning on and off the power), without waiting for the cylinder to extend or the claw to move, shortening the single insertion cycle, and adapting to the needs of automated production lines for motor production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 - Figure 5 This utility model discloses a flat wire hairpin insertion device, comprising a fixing box 1, a fixing groove 2 inside the fixing box 1, the upper end of the fixing groove 2 being U-shaped, an electromagnetic block 3 and a protective shell 4 fixedly connected to the outside of the fixing box 1, an electromagnetic block 5 and a protective shell 6 fixedly connected to the top of the fixing box 1, and an adjustment component 7 fixedly connected to the top of the protective shell 6. The angle of the fixed flat wire hairpin is adjusted by the adjustment component 7. The adjustment component 7 adjusts the height under the action of the lifting component 8, and adjusts the horizontal position under the action of the horizontal displacement component 9.

[0023] Electromagnetic block 3 is located inside the protective shell 4, and electromagnetic block 5 is located inside the protective shell 6. Protective shell 4 is bolted to the outside of the fixed box 1, isolating electromagnetic block 3 from the outside and protecting it. Protective shell 6 is bolted to the top of the fixed box 1, isolating electromagnetic block 5 from the outside and protecting it. The parts of the fixed box 1 that contact electromagnetic block 3 and electromagnetic block 5 are made of iron, which can be attracted by the magnetic blocks. The other parts of the fixed box 1 are made of an alloy, which cannot be attracted by the magnetic blocks. Electromagnetic block 3 is a device that uses the magnetic effect of current to achieve magnetic control. It can flexibly generate or lose magnetism by switching on and off power. Its core function is to attract and push ferromagnetic materials. By changing the direction of the current at both ends of the coil (such as reversing the positive and negative terminals of the power supply), the N and S poles of the electromagnetic block can be reversed, thus achieving "attraction" or "repulsion". Switching; When using electromagnetic block 1 3 and electromagnetic block 2 5, each needs to be connected to a suitable external power supply in conjunction with its dedicated controller, and the operation is controlled by its controller.

[0024] The adjustment component 7 includes an adjustment frame 701, on which a servo motor 702 is fixedly mounted. The drive end of the servo motor 702 is fixedly connected to the protective housing 6. In use, starting the servo motor 702 will drive the protective housing 6 to rotate, and the rotation of the protective housing 6 will drive the fixed box 1 to rotate. A servo motor is a type of motor that can accurately respond to control signals to achieve precise control of speed, position, and torque. Its core advantage is "closed-loop feedback + high-precision following". It is widely used in automation scenarios that require dynamic adjustment and precise positioning. The servo motor 702 is a servo motor with a self-locking structure. When using the servo motor 702, it needs to be paired with a corresponding servo driver. The connection between the servo motor 702 and the feedback device (encoder) needs to be kept away from strong interference sources (such as frequency converters and high-voltage lines) to avoid positioning deviation caused by feedback signal errors. The servo motor 702 needs to be connected to a suitable external power supply.

[0025] The lifting assembly 8 includes a movable frame 801, on which a hydraulic cylinder 802 is fixedly mounted. The telescopic end of the hydraulic cylinder 802 is fixedly connected to an adjusting frame 701. In use, starting the hydraulic cylinder 802 will drive the adjusting frame 701 to move up and down, and the up and down movement of the adjusting frame 701 will drive the fixed box 1 to move up and down. It should be noted that the hydraulic cylinder 802 needs to be used in conjunction with a hydraulic pump, hydraulic pipeline, etc., and the hydraulic pump and its controller need to be connected to a suitable external power supply.

[0026] Two sets of guide rods 10 are fixedly connected to the top of the adjustment frame 701. Both sets of guide rods 10 slide through the inner side of the movable frame 801. The guide rods 10 enable the adjustment frame 701 to move stably up and down.

[0027] The horizontal displacement assembly 9 includes a displacement frame 901, on which a screw 902 is rotatably mounted via bearings. A servo motor 903 is fixedly mounted on the displacement frame 901, and the drive end of the servo motor 903 is fixedly connected to the screw 902 via a coupling. Two sets of sliders on electric slide rails 904 are fixedly connected to both ends of the displacement frame 901 respectively. In use, starting the servo motor 903 will drive the screw 902 to rotate. A servo motor is a type of motor that can precisely control control signals to achieve precise control of speed, position, and torque. Its core advantage is "closed-loop feedback +..." "High-precision following" is widely used in automation scenarios requiring dynamic adjustment and precise positioning. Servo motor 903 is selected with a self-locking structure. Servo motor 903 requires a corresponding servo driver and its connection to the feedback device (encoder) must be kept away from strong interference sources (such as frequency converters and high-voltage lines) to avoid positioning deviations caused by feedback signal errors. Servo motor 903 requires an external power supply. During use, activating two sets of electric slide rails 904 simultaneously will move the displacement frame 901. One set of electric slide rails 904 is designated as the "active rail" and the other as the "passive rail". The active rail runs according to instructions, and its driver or motor feedback signal (such as encoder data) serves as the "target signal" for the passive rail. The passive rail follows the running state of the active rail in real time and corrects its own deviation. Both sets of electric slide rails 904 need to be paired with motors with feedback functions (such as servo motors or stepper motors + encoders), and the driver must support "master-slave mode". Both sets of electric slide rails 904 require an external power supply.

[0028] The screw 902 is threadedly connected to the inner side of the movable frame 801, and the upper end of the movable frame 801 is slidably connected to the displacement frame 901; the rotation of the screw 902 will drive the movable frame 801 to move back and forth along the displacement frame 901.

[0029] The two sets of electric slide rails 904 are respectively fixedly installed on the top of the two sets of support frames 11, and the two sets of support frames 11 are fixedly installed on the top of the workbench 12; thus making the installation structure of the device stable.

[0030] The working principle of this utility model is as follows: When in use, the electromagnetic block 3 is energized to generate strong magnetism. The upper end of the flat wire hair clip enters the fixing groove 2 and is firmly attracted. Then, the servo motor 903 is started, which drives the screw 902 to rotate. The rotation of the screw 902 will drive the moving frame 801 to move back and forth along the displacement frame 901. At the same time, the two sets of electric slide rails 904 are started, which will drive the displacement frame 901 to move. The movement of the displacement frame 901 will drive the moving frame 801 to move, thereby moving the moving frame 901 to a suitable horizontal position in all directions, so that the flat wire hair clip attracted by the fixing box 1 is above the inserted workpiece.

[0031] Then, starting the hydraulic cylinder 802 will cause the adjusting frame 701 to move down. The downward movement of the adjusting frame 701 will cause the fixing box 1 to move down. The downward movement of the fixing box 1 will cause the flat wire hair clip to move down and insert into the workpiece. Then, the electromagnetic block 3 will be de-energized and lose its strong magnetism, so that the flat wire hair clip cannot be attracted into the fixing groove 2. Then, the electromagnetic block 5 will be energized. Here, it is necessary to pay attention to the current direction at both ends of the coil (reverse the positive and negative terminals of the power supply). The N and S poles of the electromagnetic block can be reversed, so that the energization of the electromagnetic block 5 will repel the flat wire hair clip below it. Since the upper end of the flat wire hair clip is slidably inserted into the fixing groove 2, at this time, the flat wire hair clip will slide down out of the fixing groove 2 and insert into the workpiece under the repulsion of the electromagnetic block 5, thus preventing the flat wire hair clip from getting stuck in the fixing groove.

[0032] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
