DETAILED DESCRIPTION

[0025] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0026] The terms "top surface", "bottom surface" and "underside" are based on the normal use state of the ultrasonic welding machine and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0027] like Figure 2-8 As shown, an ultrasonic welding machine for antenna shell welding includes a machine base 1 and a welding head 7 which is lifted and arranged directly above the machine base 1. A positioning seat 3 is arranged on the top surface of the machine base 1 directly opposite to the welding head 7. The top surface of the positioning seat 3 has a limiting groove 301 for accommodating the antenna shell 2. A ventilation mechanism connected to the limiting groove 301 is provided inside the positioning seat 3. The ventilation mechanism is connected to an air pump 4 through an air pipe 6.

[0028] When the above-mentioned ultrasonic welding machine is used, the antenna shell 2 to be welded is placed inside the limiting groove 301 for positioning, and the welding head 7 is lowered to weld the antenna shell 2. After the welding is completed, the air pump 4 is started, and the air flow inside the air pipe 6 is driven by the air pump 4, so that the air flow inside the ventilation mechanism and the limiting groove 301 is achieved. Since the ventilation mechanism is arranged inside the positioning seat 3, the heat on the antenna shell 2 and the positioning seat 3 can be taken away by the air flow, and the antenna shell 2 and the positioning seat 3 can be quickly cooled, thereby shortening the cooling time of the antenna shell 2, improving the efficiency of the ultrasonic welding machine in welding the antenna shell 2, and at the same time reducing the probability of the operator's hands being burned, thereby improving the safety of the equipment.

[0029] Compared with the prior art, the ultrasonic welding machine can control the ventilation mechanism to absorb the air inside the limiting groove 301 or inject air into the limiting groove 301 by controlling the forward and reverse rotation of the air pump 4. When the air inside the limiting groove 301 is absorbed, a negative pressure can be generated inside the limiting groove 301, thereby generating suction to fix the antenna housing 2, thereby improving the stability of the antenna housing 2 and further improving its welding accuracy; when air is injected into the limiting groove 301, the air pressure inside the limiting groove 301 can be increased, thereby pushing the antenna housing 2 out from the limiting groove 301, facilitating the grabbing of the antenna housing 2 and improving the convenience of using the equipment.

[0030] A further improvement is, Figure 4 and 6 As shown, the ventilation mechanism includes ventilation holes 306 vertically opened at the bottom of the limiting groove 301, and a main ventilation channel 303 opened inside the positioning seat 3, and the ventilation holes 306 are connected to the air pipe 6 through the main ventilation channel 303. When the ultrasonic welding machine is used, the number of ventilation holes 306 can be set according to demand, and the air pump 4 is connected to each ventilation hole 306 through the air pipe 6 and the main ventilation channel 303. When the air pump 4 is running, an airflow is generated at the ventilation hole 306 to blow into the limiting groove 301, and the antenna housing 2 is quickly cooled by the airflow; and when the airflow passes through the main ventilation channel 303, it can also take away the heat on the positioning seat 3, and at the same time realize the cooling of the positioning seat 3, reducing the probability of burns to the operator.

[0031] A further improvement is, Figure 7 As shown, a plurality of branch ventilation channels 304 are provided inside the positioning seat 3, one end of the branch ventilation channel 304 is connected to the main ventilation channel 303, and the other end of the branch ventilation channel 304 is connected to the outside of the positioning seat 3. When the ultrasonic welding machine is in use, the provision of the branch ventilation channel 304 can extend the distance of the airflow flowing inside the positioning seat 3, and improve the heat dissipation effect of the positioning seat 3; and the branch ventilation channel 304 can play a role in pressure relief, preventing excessive or insufficient air pressure from being generated inside the limiting groove 301, reducing the probability of the antenna housing 2 being affected by air pressure during welding or taking and placing, and improving the convenience of using the equipment.

[0032] When the above ultrasonic welding machine is used, if the antenna housing 2 is cooled during the welding process, the welding quality of the antenna housing 2 will be affected, and energy loss will be caused, and the production cost will be increased. For this reason, a further improvement is as follows: Figure 3 and 4 As shown, the end of the ventilation hole 306 is covered with a top plate 5, and the top plate 5 is connected to the bottom surface of the limiting groove 301 through an elastic member.

[0033] When the ultrasonic welding machine is in use, during the welding process, the welding head 7 presses the antenna housing 2 downward, thereby pressing the top plate 5 downward through the antenna housing 2, and covering the ventilation hole 306 through the top plate 5, so that when the welding head 5 welds the antenna housing 2, the airflow inside the ventilation hole 306 will not enter the inside of the limiting groove 301, so that the antenna housing 2 can be quickly heated up to complete the welding; after the welding is completed, the welding head 7 rises, and the pressure of the welding head 7 on the antenna housing 2 disappears, then the top plate 5 is pushed upward by the elastic member, and at this time the ventilation hole 306 is opened and connected to the inside of the limiting groove 301, then the airflow inside the ventilation hole 306 enters the inside of the limiting groove 301, and the antenna housing 2 is cooled down, so that the welding efficiency and cooling efficiency of the antenna housing 2 can be improved, and the production efficiency of the ultrasonic welding machine can be further improved.

[0034] A further improvement is, Figure 4 and 8 As shown, a guide hole 307 is coaxially provided in the ventilation hole 306, and a guide rod 502 is coaxially slidably provided in the guide hole 307, and the guide rod 502 is fixedly connected to the top plate 5. The guide rod 502 slides along the guide hole 307, and the guide hole 307 realizes the limiting and guiding effect on the guide rod 502, and the top plate 5 is guided by the guide rod 502, thereby improving the stability of the top plate 5.

[0035] A further improvement is, Figure 3-6 As shown, the bottom surface of the limiting groove 301 is provided with a groove 305 for accommodating the top plate 5, and the depth of the groove 305 is greater than or equal to the thickness of the top plate 5. The setting of the groove 305 can be used to accommodate the top plate 5, realize the storage of the top plate 5, and reduce the occupation of the internal space of the limiting groove 301 by the top plate 5; when the top plate 5 is completely stored in the groove 305, the top surface of the top plate 5 is flush with the bottom surface of the limiting groove 301, which can reduce the impact on the antenna housing 2 and improve the positioning accuracy of the antenna housing 2.

[0036] A further improvement is, Figure 3 As shown, at least one side wall of the limiting groove 301 is provided with a notch 302. The notch 302 is provided so that the operator's finger can be inserted, so that the operator can grasp the antenna housing 2 with his finger, and the convenience of grasping the antenna housing 2 is improved; and when the airflow inside the vent 306 enters the limiting groove 301, the airflow can flow out from the notch 302, so that the airflow can contact the side of the antenna housing 2, and the cooling speed of the antenna housing 2 can be improved, and the cooling speed of the grasping part of the antenna housing 2 can be improved, and the production efficiency and safety of the ultrasonic welding machine are improved.

[0037] A further improvement is, Figure 4As shown, the elastic member is a spring 501, and the diameter of the spring 501 is smaller than the diameter of the ventilation hole 306, and larger than the diameter of the guide hole 307. In the ultrasonic welding machine, the spring 501 can be accommodated inside the ventilation hole 306, reducing the occupation of the spring 501 in the internal space of the limiting groove 301, making the device structure more compact and more convenient to use.
