Description

Technical Field

[0001] The invention relates to the field of transformer production, in particular to a transformer follow-up glue dispensing device. Background Art

[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to change AC voltage, current and impedance. It plays a vital role in power systems and electronic equipment.

[0003] Transformer glue dispensing is a key process in transformer production. By applying glue to specific parts, it can achieve functions such as structural fixation, vibration reduction and noise reduction, and insulation protection, which has a significant impact on the performance and reliability of the transformer.

[0004] Glue dispensing on transformers has the following functions: Fixing the magnetic core: The magnetic core of a high-frequency transformer usually consists of two parts (such as EE type, EI type, etc.). Glue dispensing can firmly bond the two parts to form a reliable magnetic circuit structure, maintain the stability of the inductance, and ensure the long-term normal operation of the transformer. Shock absorption and noise reduction: When the transformer is working, the core and winding will generate vibration noise due to the action of current and magnetic field. Filling the air gap by gluing the center column and using soft glue to absorb vibration can effectively reduce noise. Prevent displacement: Glue dispensing on the skeleton can fix the relative position of the skeleton and the core, prevent relative displacement between the coil and the core, and ensure the structural strength and reliability of the transformer. Prevent glue intrusion: Glue dispensing on the periphery fills soft glue between the transformer skeleton and the core, and between the skeletons, to prevent glue from entering the inside of the transformer when the end customer is gluing, thereby avoiding affecting the inductance.

[0005] In the existing transformer dispensing process, the transformer is first grabbed by a robot and placed on a pallet, and then the dispensing operation is performed sequentially.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] like Figure 1 As shown, a transformer follow-up glue dispensing device includes a conveyor belt 1 for conveying transformers, a positioning mechanism for locating the intervals between transformers on the conveyor belt 1, and a glue dispensing mechanism for dispensing glue on the transformers on the conveyor belt; like Figure 4 and Figure 5As shown, the dispensing mechanism includes a support platform 2 arranged on the side of the conveyor belt 1, a mobile frame 3 arranged on the support platform 2 and moving along the conveying direction of the conveyor belt 1, a lifting plate 4 arranged on the mobile frame 3 and raised and lowered on the mobile frame 3, and a dispensing gun 5 arranged on the lifting plate 4. The lifting plate 4 and the mobile frame 3 are connected by a guide rail slider. The lifting plate 4 is provided with a clamp for holding the dispensing gun 5. The mobile frame 3 is provided with a first drive mechanism to drive the lifting plate 4 up and down, and the support platform 2 is provided with a second drive mechanism to drive the mobile frame 3 to move. The conveyor belt 1 conveys the transformer and moves to the right in sequence. Under the action of the first drive mechanism, the dispensing gun 5 descends to cooperate with the transformer and dispenses glue to the transformer. At the same time, under the action of the second drive mechanism, the mobile frame 3 moves to the right, and the dispensing gun 5 moves right with the corresponding transformer, realizing non-stop follow-up dispensing and improving dispensing efficiency. After dispensing is completed, the first drive mechanism drives the dispensing gun 5 to move up, and the second drive mechanism drives the mobile frame 3 to move left. The dispensing gun 5 returns to its original position and dispenses glue to the next transformer.

[0024] like Figure 5 As shown, the first driving mechanism includes a first rotating shaft 6 arranged on the moving frame 3 and rotating on the moving frame 3, and a turntable 7 arranged at the front end of the first rotating shaft 6, the turntable 7 is provided with a guide groove 8, and the guide groove 8 is cam-shaped, and the upper end of the lifting plate 4 is provided with a first guide wheel 9 that cooperates with the guide groove 8; the moving frame 3 is provided with a vertical plate for supporting the first rotating shaft 6, the first rotating shaft 6 passes through the vertical plate and is rotatably connected to the vertical plate through a bearing, and when the first rotating shaft 6 rotates, it drives the turntable 7 to rotate, and under the action of the guide groove 8 and the first guide wheel 9, the lifting plate 4 rises and falls.

[0025] like Figure 3 As shown, the second driving mechanism includes a second rotating shaft 10 provided on the support platform 2 and rotating on the support platform 2, and a driving disk 11 provided at the end of the second rotating shaft 10. The driving disk 11 is connected to the mobile frame 3 at an eccentric position via a connecting rod 12. One end of the connecting rod 12 is connected to the eccentric position of the driving disk 11 for rotation, and the other end of the connecting rod 12 is connected to the mobile frame 3 for rotation. A motor for driving the second rotating shaft 10 to rotate is provided on the support platform 2. The motor drives the second rotating shaft 10 to rotate via a belt. Therefore, the second rotating shaft 10 is a driving shaft. The figure does not show this. This is prior art and will not be described in detail here. The second rotating shaft 10 drives the driving disk 11 to rotate. Under the action of the connecting rod 12, the mobile frame 3 continuously moves back and forth.

[0026] like Figure 4 As shown, a vertical plate 13 is provided at the front end of the support platform 2, and the movable frame 3 is connected to the vertical plate 13 via a guide rail slider.

The second rotating shaft 10 is connected to the first rotating shaft 6 via the No. 1 belt 16 and the No. 2 belt 17.

[0028] When the mobile frame 3 moves, it is necessary to ensure the synchronous rotation of the second rotating shaft 10 and the first rotating shaft 6. When the second rotating shaft 10 rotates, it drives the No. 1 belt 16 to move, and the No. 1 belt 16 drives the No. 2 belt 17 to move, thereby causing the first rotating shaft 6 to rotate accordingly. In this process, two coaxially arranged pulleys are fixed on the axle pin that hinges the No. 1 connecting rod 14 and the No. 2 connecting rod 15. One of the pulleys is connected to the second rotating shaft 10 through the No. 1 belt 16, and the other pulley is connected to the first rotating shaft 6 through the No. 2 belt 17.

Clamping blocks 27 are provided at the lower ends of the clamping plates 26. Guide plates 28 are provided at both ends of the portal frame 24, each with a guide hole 29 formed therein. The guide hole 29 comprises a vertical portion and an outwardly curved portion disposed at the lower end of the vertical portion. A second guide wheel 30 is provided at the upper end of the clamping plate 26, which engages with the guide hole 29. When the lifting frame 25 descends, the lower end of the clamping plate 26 swings inward under the action of the guide hole 29 and the second guide wheel 30, causing the clamping blocks 27 to clamp the transformer, thereby sequentially clamping and positioning the transformer and ensuring the transformer is transported at a constant distance on the conveyor belt.

[0033] A cylinder 31 for driving the lifting frame 25 to move up and down is provided at the upper end of the door-shaped frame 24 . The cylinder body end of the cylinder 31 is fixed on the door-shaped frame 24 , and the piston rod end of the cylinder 31 is connected to the lifting frame 25 .

[0034] The clamping plate 26 is a structure that is bent inward in the middle. A groove 32 is provided at the lower end of the door-shaped frame 24. The middle position of the clamping plate 26 is rotatably connected to the inner wall of the groove 32.
