Specific embodiments

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] With reference to Figure 1 , Figure 3 and Figure 4 , the utility model provides an embodiment: a kind of self-adaptive frequency regulating mechanism of ultrasonic welding equipment, including support 13, the upper side of support 13 is fixedly connected with base 1, the inside of support 13 is equipped with control box 12, the upper side of base 1 is provided with welding assembly 2, welding assembly 2 includes support column 23, support column 23 is fixedly connected on base 1, the front side of support column 23 is equipped with welding shell 21, the lower side of welding shell 21 is equipped with welding head 22, support 13 is fixedly installed with fixed frame 7, fixed frame 7 is set at the left side of base 1, the lower side of fixed frame 7 is fixedly connected with spring 8, the side of spring 8 away from fixed frame 7 is fixedly connected with connecting plate 10, the lower side of connecting plate 10 is fixedly connected with pressure head 9, pressure head 9 is slidably connected on the upper side of base 1, the left side of connecting plate 10 is fixedly connected with rack 6, the right side of rack 6 is provided with gear 5, gear 5 is fixedly connected with rotating shaft 4, the front side of rotating shaft 4 is equipped with capacitor 3, gear 5 and rack 6 are engagedly connected, gear 5 is rotatably connected on the front side of capacitor 3, capacitor 3 is installed on the back of control box 12, capacitor 3 and control box 12 are electrically connected;

[0026] Specifically, when the welding device starts to work, the pressure head 9 is in close contact with the material to be welded under the elastic force of the spring 8. Due to the different thicknesses of the material to be welded, the pressure head 9 will be displaced upward or downward to a corresponding degree, and the displacement of the pressure head 9 will drive the connecting plate 10 connected thereto to move. During the movement of the connecting plate 10, the rack 6 connected thereto will slide along the predetermined track. Since the rack 6 is in meshing connection with the gear 5, the linear sliding of the rack 6 will inevitably drive the gear 5 to rotate around the rotating shaft 4. The capacitor 3 is installed on the front side of the rotating shaft 4, and the rotation of the gear 5 will drive the rotating shaft 4 to rotate synchronously, thereby changing the capacitance value of the capacitor 3. The capacitor 3 and the control box 12 are electrically connected through a circuit, so that the change of the capacitance value will be detected by the circuit in the control box 12 immediately. According to the detected capacitance value change, the control box 12 will accurately adjust the output frequency of the welding device through internal preset circuit logic operation, so as to realize the self-adaptive adjustment of the welding frequency according to the material thickness. After the frequency adjustment is completed, the welding device performs welding operation on the material to be welded through the welding head 22.

[0027] With reference to Figure 1 and Figure 2 , the right side of the support 13 is provided with a dust removal assembly 11. The dust removal assembly 11 comprises a collection box 111 installed on the right side of the support 13. A fan 113 is installed on the lower side of the collection box 111. A dust suction cover 112 is in communication with the upper side of the collection box 111. A drawer 114 is arranged in the collection box 111. The dust suction cover 112 is arranged on the right side of the base 1.

[0028] Specifically, before the welding process starts, the operator can start the fan 113. After the fan 113 is started, a strong suction force will be generated. Under the action of the suction force, the dust attached to the surface of the material to be welded is sucked into the dust suction cover 112. The dust enters the collection box 111, and gradually settles under the action of gravity and is stored in the drawer 114 in the collection box 111. When the dust in the drawer 114 accumulates to a certain degree and affects the dust collection effect, the drawer 114 can be pulled out of the collection box 111, and the dust in the drawer 114 can be cleaned. After cleaning, the drawer 114 is reinstalled into the collection box 111 to continue collecting dust and maintain the cleanliness of the welding environment.

[0029] Working principle: when the device is used, when the welding equipment works, the pressure head 9 is in contact with the material to be welded under the action of the spring 8, the different thickness of the material to be welded will make the pressure head 9 move upward or downward to different degrees, and then drive the connecting plate 10 to move, the connecting plate 10 drives the rack 6 to slide, because the rack 6 is meshed with the gear 5, the movement of the rack 6 will drive the gear 5 to rotate around the rotating shaft 4, and the capacitor 3 is installed on the front side of the rotating shaft 4, the rotation of the gear 5 drives the rotating shaft 4 to rotate, thereby changing the capacitance value of the capacitor 3, because the capacitor 3 is electrically connected with the control box 12, the change of the capacitance value will be detected by the circuit in the control box 12, the control box 12 adjusts the output frequency of the welding equipment according to the change of the capacitance value, realizes the self-adaptive adjustment of the welding frequency according to the thickness of the material, and then welds through the welding head 22 after adjustment.

[0030] Before the welding process, the fan 113 can be started, and strong suction will be generated, under the action of the suction of the fan 113, the dust generated on the surface of the material to be welded is sucked into the dust cover 112, and the dust enters the inside of the collecting box 111 through the dust cover 112, and the dust will settle in the collecting box 111 and be stored in the drawer 114, when the dust in the drawer 114 accumulates to a certain degree, the drawer 114 can be pulled out from the collecting box 111 for cleaning.

[0031] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
