Description

Technical Field

[0002] During the production of battery circuit boards and substrates, nitrogen and dust are generated. These gases and dust need to be discharged through ventilation ducts, which require a certain air pressure to effectively extract them. Therefore, it is necessary to measure the air velocity in the ventilation system ducts and control it within a reasonable range to ensure safe production. Currently, an anemometer is used to measure the air velocity in the ventilation ducts of battery substrate production equipment. The anemometer is connected to two connecting pipes installed in the direction of fluid movement. The pressure difference generated between the two connecting pipes is used to measure the gas velocity, volume, and pressure.

[0003] Although the existing wind speed detectors can basically meet the wind speed measurement requirements of the ventilation ducts of battery base material production equipment, the following defects still exist: the circuit board of the existing wind speed detectors has low installation stability, and the components are prone to overheating during daily use in high-temperature environments, which leads to component damage, reduces product lifespan, and increases the cost of replacing circuit boards; in addition, the existing wind speed detectors have insufficient assembly sealing, which makes them prone to water leakage in open-air environments, leading to component damage.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] like Figure 1-4 As shown, a wind speed detection device is used in battery production equipment. This device is primarily used in battery production equipment where nitrogen and dust are generated during the processing of circuit boards and substrates. These nitrogen and dust are pumped out through pipeline G within the battery production equipment. Therefore, the wind speed detection device is needed to monitor the wind speed, airflow, and temperature of pipeline G in real time to ensure safe operation of the battery production equipment.

[0032] The wind speed detection device applied to battery production equipment includes a base 10, a cover 11, a connecting pipe 40, a pitot tube 41, a heat sink 12, and a control board 30. The base 10 has an integrally formed foot 106 at its bottom end, with an opening for easy installation. The base 10 has an upward-facing cavity 100. The outer wall of the base 10 has a positive end 101 and a negative end 102 for connecting the connecting pipe 40, with the positive and negative ends facing opposite directions. Both the positive and negative ends 101 and 102 have connecting holes 103 that connect to the cavity 100. The connecting pipe 40 can pass through the connecting holes 103 via an air pipe and connect to the cavity 100 of the base 10.

[0033] The other end of the connecting pipe 40 connected to the positive end 101 and the negative end 102 of the base 10 is connected to the Pitot tube 41 through the fixing sleeve 42. The Pitot tube 41 is inserted into the pipe G to detect the wind speed in the pipe G.

[0034] The outer wall of the base 10 is provided with a terminal 104 for connecting wires. The terminal 104 is connected to the cavity 100 through a wiring hole 105, so that the wire can be connected to the cavity 100 through the wiring hole 105.

[0035] The cover 11 has an internal thread, and the upper end of the seat 10 has an external thread. The cover 11 covers the opening of the cavity 100, and the cover 11 is threadedly connected to the upper end of the seat 10.

[0036] The inner wall of the cavity 100 is provided with a support block 13 extending toward the middle of the cavity 100. The support block 13 is also connected to the bottom of the cavity 100. The control board 30 and the heat sink 12 are installed inside the cavity 100. The control board 9 has a main control module 300 and a display module 305.

[0037] Specifically, the heat sink 12 has heat dissipation fins 120 in the middle, and the upper and lower ends of the heat sink 12 are connected to the display module 305 and the main control module 300 respectively. The display module 305 and the main control module 300 are arranged in parallel. The edges of the display module 305 and the main control module 300 are arc-shaped and match and fit against the inner wall of the base 10. Moreover, the main control module 300 is supported on the support block 13 on the inner wall of the cavity 100, thereby providing a stable assembly base for the control board 30 and the heat sink 12.

[0038] Both the support block 13 and the main control module 300 are provided with connection holes 130. When installing the main control module 300, the connection holes 130 of the main control module 300 are correspondingly set with the connection holes 130 of the support block 13 and connected by screws. Since the heat sink 12 is installed on the main control module 300, the main control module 300 and the heat sink 12 are thus stably installed in the cavity 100 of the base body 10.

[0039] The display module 305 is mounted on the heat sink 12. Both ends of the display module 305 are arc-shaped and can fit snugly against the inner wall of the cavity 100. Furthermore, the display module 305 does not protrude above the opening of the cavity 100 when installed inside the cavity 100. When installing the display module 305, both the heat sink 12 and the display module 305 have connection holes 130. The connection holes 130 of the heat sink 12 and the connection holes 130 of the display module 305 are correspondingly arranged and connected by screws, thereby fixing the display module 305 to the upper end of the heat sink 12.

[0040] The wires connected to the wiring holes 105 of the terminal block 104 of the base 10 can be connected to the electrical components on the display module 305 and the main control module 300, so that the heat generated by the electrical components on the display module 305 and the main control module 300 during operation can be conducted and dissipated through the heat dissipation fins 120 on the heat sink 12.

[0041] In this way, a heat sink 12 is provided inside the cavity 100 of the base 10. The main control module 300 and the display module 305 of the control board 9 are correspondingly connected to the upper and lower ends of the heat sink 12. Moreover, by setting the main control module 300 to be fixedly connected to the support block 13 on the inner wall of the cavity 100, the heat sink 12 and the display module 305 at its upper end can be stably installed inside the cavity 100. Furthermore, the main control module 300 and the display module 305 of the control board 30 can be efficiently cooled through the heat sink fins 120 of the heat sink 12 during operation. Compared with the previous wind speed detectors that lacked a heat dissipation structure, the service life of the control board 30 of this application is extended by at least 2 times. Moreover, the stable connection between the support block 16 and the control board 30 can prevent the control board 30, the heat sink 12, the display module 305 and other components from being damaged by collision inside the base 10.

[0042] The cavity 100 of the base 10 is provided with a plurality of support blocks 13, which are arranged circumferentially along the inner wall of the cavity 100. When the main control module 300 and the heat sink 12 are installed, the circumferential surface of the main control module 300 at the lower end of the heat sink 12 can be supported on the support blocks 13, thereby allowing the main control module 300 and the heat sink 12 to be installed flat. In addition, a reinforcing block 14 is provided on one side wall of the cavity 100 that connects to the connecting pipe hole 103. The two ends of the reinforcing block 14 extend toward the connecting pipe hole 103 of the two connecting pipes 40, and the reinforcing block 14 is approximately crescent-shaped or semi-circular. The reinforcing block 14 extends from the inner wall of the cavity 100 toward the middle of the cavity 100.

[0043] A support block 13 is provided on the side of the reinforcing block 14 away from the inner wall of the connecting cavity 100. The surface of the reinforcing block 14 is flush with the surface of the support block 13, so that the main control module 300 and the heat sink 12 can be supported on the reinforcing block 14 and the support block 13 at the same time. A support block 13 is also provided on one side wall of the cavity 100 that connects to the wiring hole 105, and the other side of the main control module 300 can be supported on the support block 13.

[0044] In this way, by setting the support block 13 on the reinforcing block 14 and using it together to support the main control module 300, the main control module 300 can be supported on the reinforcing block 14 and the support block 13 with a larger area, further improving the installation stability of the main control module 300 and the heat sink 12 and display module 305 installed on it. In addition, the air pipe connected to the cavity 100 through the connecting pipe hole 103 of the positive end 101 and the negative end 102 can also be placed on the reinforcing block 14, which facilitates the control board 30 to detect the airflow and air pressure of the connecting pipe 40.

[0045] The base 10 and the opening of the cavity 100 are provided with a lens 20, a locking ring 21, and a sealing ring 22 from top to bottom. Flat washers 23 are attached to the upper and lower surfaces of the lens 20, and the sealing ring 22 is fitted around the external thread at the upper end of the base 10. When the cover 11 is placed on the base 10, the cover 11 is threaded to the upper end of the base 10 and is sealed by the sealing ring 22, thus pressing them together to make the connection between the cover 11 and the base 10 more stable and the sealing performance better.

[0046] Furthermore, the inner side of the cover 11 and the opening of the cavity 100 can press the flat washers 23 on the upper and lower surfaces of the lens 20, thereby fixing the lens 20 between the cover 11 and the base 10. The flat washers 23 are made of plastic. By setting the flat washers 23 on the upper and lower surfaces of the lens 20, they have a buffering effect during the installation of the lens 20, preventing the lens 20 from being crushed.

[0047] Furthermore, the locking ring 21 secures the lens 20 and the flat washer 23 around its perimeter, preventing the lens 20 and flat washer 23 from becoming loose and affecting the assembly effect. This ensures that the lens 20 is installed more compactly and stably between the cover 11 and the base 10. Since the cover 11 has a cover hole 110 in the center, and when the cover 11 is placed on top of the base 10, its cover hole 110 corresponds to the lens 20, allowing the user to see the interior of the cavity 100 of the base 10 through the cover hole 110 and the lens 20.

[0048] The control board 30 is also equipped with a pressure module 301, a comparison module 302, a power supply module 303, and a temperature module 304 that are electrically connected to the main control module 300. The main control module 300 can be a microcontroller with an embedded control program. The main control module 300 obtains power through an electrical connection to the power supply module 303. After the main control module 300 is powered on, it can send commands to control the operation of functional modules such as the pressure module 301, the comparison module 302, the temperature module 304, and the display module 305.

[0049] In this application, the pressure module 301 can be a pressure sensor. The positive end 101 of the base 10 is connected to the connecting pipe 40 for air intake. The main control module 300 sends a command to control the pressure module 301 to detect the airflow in the connecting pipe 40 connected to the positive end 101 of the base 10 and obtain the total pressure signal. The negative end 102 of the base 10 is connected to the connecting pipe 40 for air outlet. The main control module 300 sends a command to control the pressure module 301 to detect the airflow in the connecting pipe 40 connected to the negative end 102 of the base 10 and obtain the static pressure signal.

[0050] The comparison module 302 of this application can be a comparator. The main control module 300 sends commands to control the comparison module 302 to compare and analyze the total pressure signal and static pressure signal acquired by the pressure module 301. The comparison module 302 outputs current and voltage signals based on the comparison and analysis results. The main control module 300 also sends commands to control the temperature module 304 to acquire the temperature value of the airflow in pipe G. In practical applications, total pressure minus static pressure equals dynamic pressure. The main control module 300 can calculate and analyze the dynamic pressure and obtain the wind speed and air volume values ​​of pipe G by embedding the Bernoulli equation. The specific calculation process is prior art and will not be described in detail here.

[0051] The wind speed, airflow, and temperature values ​​of the above-mentioned pipe G can be displayed by the display module 305 via commands sent by the main control module 300. Users can observe these data through the lens 20 via the cover hole 110 of the cover 11. In this way, the main control module 300 controls the pressure module 301, comparison module 302, and temperature module 304 to monitor and provide feedback on the airflow in pipe G in real time, keeping the wind speed in pipe G within a reasonable range and ensuring the safe operation of the battery production equipment.

[0052] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
