Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, specifically to a transducer housing and a transducer. Background Technology

[0002] Ultrasonic welding utilizes high-frequency vibration waves (typically exceeding 15kHz) transmitted to the surfaces of two workpieces to be welded. Under pressure, the surfaces of the two workpieces rub against each other, forming a fusion between molecular layers. This welding method requires no solder or external heat source and has advantages such as high efficiency, environmental friendliness, high welding strength, and low welding cost, thus it is widely used in automobile manufacturing, packaging processing, and electronic product manufacturing.

[0003] An ultrasonic transducer (hereinafter referred to as the transducer) is one of the core components of ultrasonic welding equipment. It is responsible for converting the electrical energy output from the ultrasonic generator into mechanical vibrations of the same frequency to achieve welding of the workpiece. Transducers typically have high requirements for their working environment; they should avoid contact with dust and other impurities during operation. On the one hand, dust accumulation on the ceramic plate of the transducer can easily lead to short circuits and sparking; on the other hand, dust accumulation on the transducer can also affect its heat dissipation. To solve this problem, related technologies usually use a transducer housing to prevent the transducer from being bumped during use and to reduce contamination from various dust impurities. However, in actual use, operators have found that a small amount of dust can still enter the transducer from the gap between the housing and the transducer, causing short circuits and damage.

[0004] Therefore, there is an urgent need for a transducer housing to solve the above problems. Utility Model Content

In addition, the transducer housing can also protect the transducer body, preventing it from being bumped during operation, thereby ensuring the surface quality of the transducer body. By setting a first mounting port on the housing body that can be connected to an external air source, compressed air can be introduced into the accommodating cavity through the first mounting port, making the air pressure in the accommodating cavity higher than the external air pressure, thereby further isolating external dust and impurities from entering the accommodating cavity from the connection points of the various structures of the transducer housing, thereby further ensuring the sealing performance of the entire transducer housing.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0043] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0044] In this invention, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0048] Figure 1 A schematic diagram of the transducer provided in this embodiment is shown from one viewpoint. Figure 2A cross-sectional schematic diagram of the transducer provided in this embodiment is shown. Figures 1-2 As shown, this embodiment provides a transducer including a transducer body 200 and a transducer housing 100, with a portion of the transducer body 200 disposed within the transducer housing 100. The transducer housing 100 serves to protect the transducer body 200 from impacts during use and to reduce contamination from various dust and impurities. It should be noted that this embodiment does not limit the specific structure of the transducer body 200. Any transducer body 200 used in ultrasonic welding equipment to convert the electrical energy output from an ultrasonic generator into mechanical vibrations of the same frequency is within the scope of this embodiment.

[0049] During actual use, operators have found that a small amount of dust can still enter the interior of the transducer housing 100 through the gap between the transducer housing 100 and the transducer body 200, which can easily cause short circuit damage to the transducer body 200 and affect its service life. To solve this problem, this embodiment also provides a transducer housing 100 that can prevent dust from entering through the gap between the transducer housing 100 and the transducer body 200, thereby preventing transducer damage caused by dust accumulation on the surface of the transducer body 200.

[0050] Specifically, such as Figures 1-2 As shown, the transducer housing 100 includes a housing body 110 and a first sealing member 121. The housing body 110 has a receiving cavity 1101 for accommodating part of the transducer body 200. The first sealing member 121 is disposed between the transducer body 200 and the cavity wall of the receiving cavity 1101. By setting the first sealing element 121, a seal can be formed between the transducer housing 100 and the transducer body 200 to prevent dust from entering the receiving cavity 1101 through the gap between the transducer housing 100 and the transducer body 200 and accumulating on the surface of the transducer body 200, thereby preventing damage to the transducer body 200, ensuring the performance and efficiency of the transducer body 200, and extending the service life of the transducer body 200. In addition, the transducer housing 100 can also protect the transducer body 200 from impacts during operation, thereby ensuring the surface quality of the transducer body 200.

[0051] In this embodiment, the first sealing element 121 is a rubber sealing ring, which has a good sealing effect, is easy to install, and has a low cost. To prevent the first sealing element 121 from falling off or shifting during the operation of the transducer, a first mounting groove 1122 for installing the first sealing element 121 is also provided on the cavity wall of the accommodating cavity 1101, so as to realize the positioning and installation of the first sealing element 121 and ensure its installation stability.

[0052] To facilitate the insertion of the transducer body 200 into the housing body 110, the housing body 110 includes a housing 111 and a retaining ring 112. The housing 111 has a hollow structure, and one end of the housing 111 has a first opening 1102 communicating with the cavity of the housing 111. The retaining ring 112 is installed at the first opening 1102. The housing 111 and the retaining ring 112 form the aforementioned receiving cavity 1101, and the retaining ring 112 has a clearance hole 1121 for avoiding the transducer body 200. When assembling the transducer body 200 and the housing body 110, the transducer body 200 can be inserted into the cavity of the housing 111 through the first opening 1102, and then the retaining ring 112 is installed in the first opening 1102 of the housing 111, with the end of the transducer body 200 able to pass through the clearance hole 1121. The first mounting groove 1122 is formed on the inner wall of the retaining ring 112.

[0053] To prevent external dust from entering the receiving cavity 1101 through the gap between the housing 111 and the retaining ring 112 and accumulating on the surface of the transducer body 200, a second seal 122 is provided between the housing 111 and the retaining ring 112 to ensure the sealed installation of the housing 111 and the retaining ring 112.

[0054] In this embodiment, the second seal 122 is a rubber sealing ring, which provides good sealing performance, is easy to install, and has low cost. To prevent the second seal 122 from falling off or shifting during transducer operation, a second mounting groove 1123 for installing the second seal 122 is also provided on the outer wall of the retaining ring 112, so as to achieve the positioning and installation of the second seal 122 and ensure its installation stability. Of course, in other embodiments, the second mounting groove 1123 can also be provided on the inner wall of the housing 111, which can achieve the same effect.

[0055] The housing 111 and the retaining ring 112 are fixedly connected by a first fastener 141. The first fastener 141 passes through the housing 111 and is connected to the retaining ring 112 to achieve a stable connection between the housing 111 and the retaining ring 112. Optionally, the first fastener 141 is a bolt, which has the advantages of being secure and easy to install and remove. In this embodiment, there are three first fasteners 141, which are spaced apart circumferentially along the housing 111 to further improve the stability of the connection between the housing 111 and the retaining ring 112. Of course, in other embodiments, the number of first fasteners 141 can be two, four, five, six, or even more, and this embodiment does not limit this.

[0056] Figure 3 A schematic diagram of the transducer provided in this embodiment is shown from another perspective. For example... Figure 3 and combined Figure 2 As shown, the housing 111 includes a housing body 1111 and a rear cover 1112. The housing body 1111 is a cavity structure with openings at both ends. One end of the housing body 1111 forms the aforementioned first opening 1102, and the other end forms a second opening 1103. The rear cover 1112 is installed at the second opening 1103, and a third sealing element 123 is provided between the housing body 1111 and the rear cover 1112 to ensure a sealed installation of the housing body 1111 and the rear cover 1112, preventing external dust from entering the accommodating cavity 1101 through the gap between the housing body 1111 and the rear cover 1112. It should be explained that the cavity wall of the accommodating cavity 1101 includes the inner wall of the rear cover 1112, the inner wall of the housing body 1111, and the inner wall of the retaining ring 112.

[0057] In this embodiment, the third seal 123 is a rubber sealing ring, which provides good sealing performance, is easy to install, and has low cost. To prevent the third seal 123 from falling off or shifting during transducer operation, a third mounting groove 11121 for installing the third seal 123 is also provided on the outer wall of the rear cover 1112, so as to achieve the positioning and installation of the third seal 123 and ensure its installation stability. Of course, in other embodiments, the third mounting groove 11121 can also be provided on the inner wall of the shell body 1111, which can achieve the same effect.

[0058] The shell body 1111 and the rear cover 1112 are fixedly connected by a second fastener 142. The second fastener 142 passes through the shell body 1111 and is connected to the rear cover 1112 to achieve a stable connection between the shell body 1111 and the rear cover 1112. Optionally, the second fastener 142 is a bolt, which has the advantages of a tight connection and easy assembly and disassembly. In this embodiment, there are three second fasteners 142, which are spaced apart circumferentially along the shell body 1111 to further improve the stability of the connection between the shell body 1111 and the rear cover 1112. Of course, in other embodiments, the number of second fasteners 142 can be two, four, five, six, or even more, and this embodiment does not limit this.

[0059] like Figure 1 and Figure 2 As shown, the transducer housing 100 also includes a silicone connector 130. The housing body 110 also has a second mounting port communicating with the receiving cavity 1101. The silicone connector 130 is installed in the second mounting port and used for cable routing. The cable passes through the second mounting port and is electrically connected to the transducer body 200 to supply power to the transducer body 200. By providing the silicone connector 130, the aperture of the silicone connector 130 in its natural state is slightly smaller than the outer diameter of the cable. When the cable is routed through the silicone connector 130, the silicone connector 130 can tightly wrap the cable under its own elasticity, thereby achieving a sealing effect to prevent external dust from entering the receiving cavity 1101 from the gap between the second mounting port and the cable, further ensuring the sealing performance of the entire transducer housing 100.

[0060] Continue as Figure 1 and Figure 2 As shown, the housing body 110 is also provided with a first mounting port that communicates with the accommodating cavity 1101. The first mounting port is connected to an external air source for introducing compressed air into the accommodating cavity 1101. By introducing compressed air into the accommodating cavity 1101, the air pressure in the accommodating cavity 1101 can be made greater than the external air pressure, thereby further isolating external dust and impurities from entering the accommodating cavity 1101 from the connection positions of the various structures of the transducer housing 100, so as to further ensure the sealing performance of the entire transducer housing 100.

[0061] Figure 4 This is a structural schematic diagram of the quick-connect coupling 150 provided in an embodiment of this utility model. (See attached diagram.) Figure 4 and combined Figure 1As shown, the first mounting port is connected to the connecting pipe of an external air source via a quick-connect coupling 150. Specifically, the first end 151 of the quick-connect coupling 150 is provided with an external thread, the second end 152 of the quick-connect coupling 150 is inserted into the connecting pipe of the external air source, and the first end 151 is threadedly connected to the first mounting port, thereby achieving a sealed installation between the quick-connect coupling 150 and the first mounting port, preventing external dust and impurities from entering the receiving cavity 1101 through the gap between the quick-connect coupling 150 and the first mounting port.

[0062] like Figure 2 and Figure 3 As shown, a silencer 300 is also provided at the end of the housing body 110 away from the first mounting port, and the compressed air in the accommodating cavity 1101 can be discharged from the silencer 300. It should be explained that the compressed air introduced into the accommodating cavity 1101 can cool the transducer body 200 when the transducer is working, so as to prevent the transducer body 200 from overheating and being damaged. The air after heat exchange with the transducer body 200 can be discharged from the silencer 300. At this time, the silencer 300 can also play a role in noise reduction, thereby avoiding the loud noise pollution caused by the compressed air being discharged.

[0063] In the prior art, the transducer housing 100 is typically made of black, opaque engineering plastic, making it impossible for operators to directly observe the transducer body 200 from the outside. Furthermore, the retaining ring 112 needs to be removed, which is inconvenient. To solve this problem, in this embodiment, at least a portion of the housing body 110 is made of a transparent material, allowing operators to easily observe the current state of the transducer body 200 through the transparent portion of the housing body 110 without needing to remove the retaining ring 112, thereby reducing the workload of the operator.

[0064] In one embodiment, the entire housing body 110 is made of transparent acrylic material to facilitate observation of the transducer body 200 by operators from multiple angles. In another embodiment, only the housing body 1111 may be made of transparent acrylic material, achieving the same effect.

[0065] In another embodiment, an observation port can be opened on the housing body 1111, and an observation window made of transparent acrylic material can be installed at the observation port, allowing the operator to observe the current state of the transducer body 200 through the observation window. However, with this arrangement, a gap will still exist between the observation port and the observation window. The operator needs to install a fourth sealing element between the observation port and the observation window to prevent external dust and impurities from entering the receiving cavity 1101 through the gap between the observation port and the observation window, so as to ensure the sealing performance of the entire transducer housing 100.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
