Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, and in particular to a vacuum degassing device for the production of automotive pressure sensors. Background Technology

[0002] On the pressure sensor production line, multiple unsealed sensors are placed on transport molds. The glue applicator on the production line applies glue to the inside of the sensors. After the glue application is completed, the glue needs to be degassed under vacuum.

[0003] On the production line, the transport mold carries the sensor into the degassing device. After vacuuming is completed, the mold is directly transported to the next station. At this time, the sealant is still in a flowing state and is not given time to stand and solidify. Therefore, during transportation, the uncured sealant on the surface is prone to re-entering air due to shaking, resulting in the failure of vacuum degassing. Utility Model Content

[0004] The purpose of this application is to provide a vacuum degassing device for the production of automotive pressure sensors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A vacuum degassing device for manufacturing automotive pressure sensors includes a bracket, a degassing chamber, and a degassing assembly mounted on the bracket. The degassing assembly includes a lifting plate and a functional plate. The lifting plate is movably mounted on the bracket, and the degassing chamber is located above the lifting plate. A vacuum port is opened above the degassing chamber. The functional plate is mounted above the bracket, and a suction pipe and an intake pipe are installed in pairs on the functional plate. The port of the suction pipe of the functional plate is adapted to the vacuum port on the degassing chamber. A fixing frame is fixedly mounted above the bracket, and the functional plate is movably mounted below the fixing frame.

[0007] Preferably, the top end of the suction pipe on the functional plate passes through the fixing frame, and the port of the suction pipe is connected to an external air pump pipe. A spring is installed between the functional plate and the fixing frame, and the spring is sleeved on the outside of the suction pipe. An mounting block is fixedly installed on the surface of the lifting plate. A groove is formed on the upper outer wall of the mounting block. The shape of the groove is adapted to the bottom shape of the degassing chamber, and the degassing chamber is fitted and placed on top of the mounting block.

[0008] Preferably, multiple guide rods are fixedly installed at the bottom of the lifting plate, and the guide rods are perpendicular to the lifting plate. Multiple fixing blocks are fixedly installed on the edge of the bracket, and the fixing blocks have round holes through which the guide rods pass. A cylinder is fixedly installed below the bracket, and the output end of the cylinder faces the lifting plate and is fixedly connected to the bottom surface of the lifting plate. The output direction of the cylinder is parallel to the guide rods.

[0009] The beneficial effects of this utility model are: by setting up a degassing component and using a degassing chamber transport sensor, a single degassing chamber can be transported to another location by a robotic arm after vacuum degassing treatment, and left to stand for a period of time to wait for the surface to solidify. During this process, other degassing chambers can continue to be placed on the support for processing without affecting work efficiency. At the same time, it gives the sealant time to solidify and avoids the situation of air being mixed in again. Attached Figure Description

[0015] like Figure 1-3 The vacuum degassing device for automotive pressure sensor production shown includes a bracket 1, a degassing chamber 5, and a degassing assembly mounted on the bracket 1. The degassing assembly includes a lifting plate 2 and a functional plate 4. The lifting plate 2 is movably mounted on the bracket 1, and the degassing chamber 5 is disposed above the lifting plate 2. A vacuum port is opened above the degassing chamber 5. The functional plate 4 is mounted above the bracket 1. A suction pipe 10 and an intake pipe 12 are mounted in pairs on the functional plate 4. The pipe opening of the suction pipe 10 of the functional plate 4 is adapted to the vacuum port on the degassing chamber 5. A fixing frame 3 is fixedly mounted above the bracket 1, and the functional plate 4 is movably mounted below the fixing frame 3.

[0016] The top end of the suction pipe 10 on the functional plate 4 passes through the fixing frame 3, and the end of the suction pipe 10 is connected to an external air pump pipe. A spring 11 is installed between the functional plate 4 and the fixing frame 3, and the spring 11 is sleeved on the outside of the suction pipe 10. A mounting block 6 is fixedly installed on the surface of the lifting plate 2. A groove is opened on the upper outer wall of the mounting block 6. The shape of the groove matches the bottom shape of the degassing chamber 5, and the degassing chamber 5 is fitted and placed on the mounting block 6.

[0017] Multiple guide rods 7 are fixedly installed at the bottom of the lifting plate 2, and the guide rods 7 are perpendicular to the lifting plate 2. Multiple fixing blocks 8 are fixedly installed on the edge of the bracket 1, and the fixing blocks 8 have round holes, through which the guide rods 7 pass. A cylinder 9 is fixedly installed below the bracket 1, with the output end of the cylinder 9 facing the lifting plate 2 and fixedly connected to the bottom surface of the lifting plate 2. The output direction of the cylinder 9 is parallel to the guide rods 7.

[0018] Example: An external robotic arm transports the degassing chamber 5 from the production line to the mounting block 6 of the lifting plate 2. As the cylinder 9 inside the bracket 1 is activated, the lifting plate 2 rises, which in turn moves the mounting block 6, which in turn moves the degassing chamber 5. The guide rod 7 slides inside the fixed block 8, providing movement guidance for the lifting plate 2. When the lifting plate 2 reaches a certain height, the vacuum port of the degassing chamber 5 aligns with the functional plate 4 below the fixed frame 3. The suction pipe 10 aligns with the vacuum port of the degassing chamber 5, and the spring 11 is compressed and deformed. Subsequently, the external air pump is activated to vacuum the interior of the degassing chamber 5. After vacuuming, a period of time is waited until the sealant on the sensor slightly solidifies. Then, the external robotic arm transports the degassing chamber 5 to the next workstation. The air inlet pipe 12 is connected to the external air pump, which pumps air into the degassing chamber 5 through the air inlet pipe 12. After pumping air, the degassing chamber 5 can be opened.
