Description

Technical Field

[0001] The present invention relates to the technical field of electronic component detection, and in particular, to a control device for detecting the airtightness of an electronic component and a detection device. Background Art

[0002] A quartz crystal resonator is an oscillator with high precision and high stability, and is widely used in various oscillation circuits such as color TVs, computers, and remote controls. It can also generate clock signals for frequency generators and data processing devices in communication systems or provide reference signals for specific systems. Quartz crystal resonators are generally packaged in metal shells or ceramics. After packaging, the inside of the metal shell or ceramic package shell needs to be in a vacuum state or filled with nitrogen.

[0003] In the related art, after the quartz crystal resonator is processed, a pressure tank is required to detect the vacuum degree of the crystal oscillator product. During the detection process, first, the pressure tank is opened, the crystal oscillator product is placed in the pressure tank filled with a penetrant, then the pressure tank is filled with gas and pressurized for a certain period of time, and finally the crystal oscillator product is taken out for detection to detect whether the inside of the metal shell or ceramic package shell is in a completely sealed state. Currently, the inflation time is manually controlled, and there is uncertainty in the control of the pressurization time, which may cause the detection method for the airtightness of the crystal oscillator to fail. Summary of the Invention

[0004] In order to solve or improve the technical problem of uncertainty in manually controlling the pressurization time, an object of the present invention is to provide a control device for detecting the airtightness of an electronic component.

[0005] Another object of the present invention is to provide a detection device having the above control device for detecting the airtightness of an electronic component.

[0006] To achieve the above object, a first aspect of the present invention provides a control device for detecting the airtightness of an electronic component, including: an inflation valve for connecting to a pressure tank; a deflation valve for connecting to the pressure tank; a first time relay connected to the inflation valve, the first time relay being capable of controlling the inflation valve to pressurize the pressure tank, and the time for the inflation valve to pressurize the pressure tank being a first time threshold; a second time relay connected to the deflation valve, before or after the first time relay controls the inflation valve to pressurize the pressure tank, the second time relay being capable of controlling the deflation valve to relieve pressure on the pressure tank, and the time for the deflation valve to relieve pressure on the pressure tank being a second time threshold; an intermediate relay connected to the first time relay, the intermediate relay being connected to the second time relay, and the intermediate relay being selectively conductive with the first time relay or the second time relay.

[0007] According to an embodiment of the control device for detecting the sealing performance of electronic components provided by the present invention, on the one hand, automatic control is achieved, which is beneficial to reducing the labor intensity; on the other hand, by controlling the pressurization or depressurization time of the pressure tank through a time relay, the uncertainty of manual time control is solved, and the possibility of the failure of the crystal oscillator sealing performance detection means can be reduced to a great extent.

[0008] Specifically, the control device for detecting the sealing performance of electronic components includes an inflation valve, a deflation valve, a first time relay, a second time relay, and an intermediate relay. Among them, the inflation valve is connected to the pressure tank of the detection device, and the deflation valve is connected to the pressure tank of the detection device. The inflation valve is used to inflate and pressurize the pressure tank to detect the sealing performance of the component to be detected. The deflation valve is used to depressurize the pressure tank, which is convenient for opening and putting the component to be detected into the pressure tank or taking it out of the pressure tank.

[0009] Further, the first time relay is connected to the inflation valve. The first time relay can control the inflation valve to pressurize the pressure tank. The time for the inflation valve to inflate and pressurize the pressure tank is the first time threshold. Optionally, the first time threshold is 55 min to 65 min. Further, the second time relay is connected to the deflation valve. Before or after the first time relay controls the inflation valve to pressurize the pressure tank, the second time relay can control the deflation valve to depressurize the pressure tank. In other words, the control process specifically includes: the first step, the second time relay controls the deflation valve to depressurize the pressure tank, which is convenient for opening and putting the component to be detected into the pressure tank; the second step, the first time relay controls the inflation valve to pressurize the pressure tank to detect the component to be detected; the third step, the second time relay controls the deflation valve to depressurize the pressure tank, which is convenient for opening and taking the component to be detected out of the pressure tank. Further, the time for the deflation valve to depressurize the pressure tank is the second time threshold. Optionally, the second time threshold is 10 s to 14 s. A time relay is a relay whose output circuit needs to undergo a specified accurate time to produce a jump change (or contact action) after the input action signal is added (or removed). Time relays are usually applied to circuits with relatively low voltage or small current to connect or disconnect electrical components with relatively high voltage or large current. A time relay is a very important component in an electrical control system. In many control systems, a time relay is required to achieve delay control.

[0010] Further, the intermediate relay is connected to the first time relay and the second time relay. The intermediate relay can selectively conduct with the first time relay or the second time relay. It can be understood that the intermediate relay is used to switch the circuit to control the pressure relief or pressurization of the pressure tank. The intermediate relay is usually used to transmit signals and control multiple circuits simultaneously, and can also directly control small-capacity motors or other electrical actuating elements. When selecting an intermediate relay, the voltage level and the number of contacts are mainly considered. In fact, the intermediate relay is also a voltage relay. The difference from an ordinary voltage relay is that the intermediate relay has many contacts and the current allowed to flow through the contacts is relatively large, and it can disconnect and connect circuits with relatively large currents.

[0011] In the related art, after the quartz crystal resonator is processed, a pressure tank is required to detect the vacuum degree of the crystal oscillator product. During the detection process, first, the pressure tank is opened, the crystal oscillator product is placed in the pressure tank filled with penetrant, then the pressure tank is filled with gas and pressurized for a certain period of time, and finally the crystal oscillator product is taken out for detection to detect whether the metal shell or ceramic package shell is in a completely sealed state. Currently, the inflation time is manually controlled, and there is uncertainty in the control of the pressurization time, which may cause the crystal oscillator sealing detection method to fail.

[0012] In the technical solution defined by the present invention, on the one hand, automatic control is achieved, which is beneficial to reducing the labor intensity; on the other hand, the time for pressurizing or depressurizing the pressure tank is controlled by the time relay, solving the uncertainty of manual time control, and to a great extent, reducing the possibility of the crystal oscillator sealing detection method failing.

[0013] In addition, the above technical solution provided by the present invention may further have the following additional technical features:

[0015] In this technical solution, the control device for detecting the tightness of the electronic component further includes a start button. Specifically, the start button is connected to the intermediate relay. By operating the start button, the intermediate relay can be controlled to switch the circuit, that is, the intermediate relay can selectively conduct with the first time relay or the second time relay. Further, the start button is connected to the first time relay. By operating the start button, the first time relay can control the inflation valve to pressurize the pressure tank, and the pressurization time can also be set. Further, the start button is connected to the second time relay. By operating the start button, the second time relay can control the deflation valve to depressurize the pressure tank, and the pressure relief time can also be set.

[0016] In the above technical solution, it further includes: a counter, connected to the start button.

[0017] In this technical solution, the control device for detecting the sealing performance of the electronic component further includes a counter. Specifically, the counter is connected to the start button. By setting the counter, the start times of the start button can be counted. Counting is the simplest and most basic operation. A counter is a logic circuit that realizes this operation. In a digital system, a counter mainly counts the number of pulses to achieve functions such as measurement, counting, and control, and at the same time has a frequency division function. A counter is composed of basic counting units and some control gates, and the counting units are composed of a series of flip-flops with the function of storing information.

[0018] Optionally, the counter is used to count the pressurization times to more accurately understand the pressurization time, solve the uncertainty of manual time control, and greatly reduce the possibility of the failure of the crystal oscillator sealing detection means.

[0019] In the above technical solution, it further includes: a power supply, connected to the intermediate relay, and the intermediate relay is used to conduct the power supply to the first time relay or conduct the power supply to the second time relay.

[0020] In this technical solution, the control device for detecting the sealing performance of the electronic component further includes a power supply. Specifically, the power supply is connected to the intermediate relay. The intermediate relay is used to conduct the power supply to the first time relay or conduct the power supply to the second time relay. The intermediate relay can selectively conduct with the first time relay or the second time relay. It can be understood that the intermediate relay is used to switch the circuit to control the pressure relief or pressurization of the pressure tank.

[0021] In the above technical solution, it further includes: an air switch, connected to the power supply, and the air switch is connected to the intermediate relay.

[0022] In this technical solution, the control device for detecting the sealing performance of the electronic component further includes an air switch. Specifically, the air switch is connected to the power supply, and the air switch is connected to the intermediate relay. An air switch is also known as an air circuit breaker and belongs to a type of circuit breaker. An air switch is a switch that automatically disconnects as long as the current in the circuit exceeds the rated current. By adding an air switch, in addition to being able to complete the connection and disconnection of the circuit, it can also protect the circuit to avoid situations such as short circuit, serious overload, and undervoltage.

[0023] In the above technical solution, the first time threshold is 55 min to 65 min.

[0024] In this technical solution, by setting the first time threshold to 55 min to 65 min, that is, the time for the inflation valve to inflate and pressurize the pressure tank is 55 min to 65 min, and using the first time relay to control the pressurization time of the pressure tank, the uncertainty of manual time control is solved, and the possibility of the failure of the crystal oscillator sealing detection means can be reduced to a great extent. Optionally, the first time threshold is 60 min.

[0025] In the above technical solution, the second time threshold is 10 s to 14 s.

[0026] In this technical solution, by setting the second time threshold to 10 s to 14 s, that is, the time for the deflation valve to relieve the pressure of the pressure tank is 10 s to 14 s, and using the second time relay to control the pressure relief time of the pressure tank, the uncertainty of manual time control is also solved, which is beneficial to further reducing the possibility of the failure of the crystal oscillator sealing detection means. Optionally, the second time threshold is 12 s.

[0027] The second aspect of the present invention provides a detection device, including: a pressure tank; at least one control device for detecting the sealing of an electronic component in any one of the above embodiments, the inflation valve of the control device for detecting the sealing of the electronic component is connected to the pressure tank, and the deflation valve of the control device for detecting the sealing of the electronic component is connected to the pressure tank.

[0028] According to the embodiment of the detection device of the present invention, the detection device includes a pressure tank and at least one control device for detecting the sealing of an electronic component in any one of the above embodiments. Specifically, the inflation valve of the control device for detecting the sealing of the electronic component is connected to the pressure tank, and the inflation valve can pressurize the pressure tank. The deflation valve of the control device for detecting the sealing of the electronic component is connected to the pressure tank, and the deflation valve can relieve the pressure of the pressure tank. The control process specifically includes: the first step, the second time relay controls the deflation valve to relieve the pressure of the pressure tank, which is convenient to open and put the component to be detected into the pressure tank; the second step, the first time relay controls the inflation valve to pressurize the pressure tank to detect the component to be detected; the third step, the second time relay controls the deflation valve to relieve the pressure of the pressure tank, which is convenient to open and take out the component to be detected from the pressure tank.

[0029] It should be noted that the number of control devices for detecting the sealing of electronic components is at least one. Considering factors such as the occupied space size, the inflation and pressurization or deflation and pressure relief efficiency of the pressure tank, and other factors, the control devices for detecting the sealing of electronic components are flexibly set according to actual needs.

[0030] In the above technical solution, the number of control devices for detecting the sealing of electronic components is two.

[0031] In this technical solution, by setting the quantity to two, it can be understood that there are two groups of control systems in total, and the control methods are the same. While ensuring that the occupied space will not be too large, it is beneficial to improve the efficiency of inflating and pressurizing or deflating and depressurizing the pressure tank, and achieve precise control of the pressurizing and depressurizing time.

[0032] In the above technical solution, the pressure tank is used to place the workpiece to be detected.

Detailed Embodiments

[0040] In order to more clearly understand the above objects, features and advantages of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0041] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the embodiments of the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the limitations of the specific embodiments disclosed below.

[0042] The following refers to Figure 1 and Figure 2 describe a control device 100 and a detection device 200 for detecting the sealing performance of electronic components provided according to some embodiments of the present invention.

[0043] Embodiment 1

[0044] As Figure 1 shown, a control device 100 for detecting the sealing performance of electronic components provided by an embodiment of the present invention includes an inflation valve 110, a deflation valve 120, a first time relay 130, a second time relay 140, and an intermediate relay 150. Among them, the inflation valve 110 is connected to the pressure tank 210 of the detection device 200, and the deflation valve 120 is connected to the pressure tank 210 of the detection device 200. The inflation valve 110 is used to inflate and pressurize the pressure tank 210 to perform a sealing performance test on the test piece to be detected. The deflation valve 120 is used to relieve the pressure of the pressure tank 210 to facilitate opening and putting the test piece to be detected into the pressure tank 210 or taking it out of the pressure tank 210.

[0045] Further, the first time relay 130 is connected to the inflation valve 110. The first time relay 130 can control the inflation valve 110 to pressurize the pressure tank 210. The time for the inflation valve 110 to inflate and pressurize the pressure tank 210 is the first time threshold. Optionally, the first time threshold is 55 min to 65 min. Further, the second time relay 140 is connected to the deflation valve 120. Before or after the first time relay 130 controls the inflation valve 110 to pressurize the pressure tank 210, the second time relay 140 can control the deflation valve 120 to relieve the pressure of the pressure tank 210. In other words, the control process specifically includes: the first step, the second time relay 140 controls the deflation valve 120 to relieve the pressure of the pressure tank 210 to facilitate opening and putting the test piece into the pressure tank 210; the second step, the first time relay 130 controls the inflation valve 110 to pressurize the pressure tank 210 to test the test piece; the third step, the second time relay 140 controls the deflation valve 120 to relieve the pressure of the pressure tank 210 to facilitate opening and taking the test piece out of the pressure tank 210. Further, the time for the deflation valve 120 to relieve the pressure of the pressure tank 210 is the second time threshold. Optionally, the second time threshold is 10 s to 14 s. A time relay is a relay whose output circuit needs to undergo a specified accurate time to produce a jump change (or contact action) after the input action signal is added (or removed). Time relays are usually applied to circuits with lower voltage or smaller current to connect or disconnect electrical components with higher voltage or larger current. A time relay is a very important component in an electrical control system. In many control systems, a time relay is required to achieve delay control.

[0046] Further, the intermediate relay 150 is connected to the first time relay 130 and the intermediate relay 150 is connected to the second time relay 140. The intermediate relay 150 can be selectively conducted with the first time relay 130 or the second time relay 140. It can be understood that the intermediate relay 150 is used to switch the circuit to control the pressure relief or pressurization of the pressure tank 210. The intermediate relay 150 is usually used to transmit signals and control multiple circuits simultaneously, and can also directly control a small-capacity motor or other electrical actuators. When selecting the intermediate relay 150, the voltage level and the number of contacts are mainly considered. The intermediate relay 150 is actually also a voltage relay. The difference from an ordinary voltage relay is that the intermediate relay 150 has many contacts and the current allowed to flow through the contacts is relatively large, and it can disconnect and connect circuits with larger current.

[0047] In the related art, after the quartz crystal resonator is processed, a pressure tank 210 is required to detect the vacuum degree of the crystal oscillator product. During the detection process, first, the pressure tank 210 is opened, and the crystal oscillator product is placed into the pressure tank 210 filled with a penetrant. Then, the pressure tank 210 is filled with gas and pressurized for a certain period of time. Finally, the crystal oscillator product is taken out for detection to check whether the metal housing or the ceramic package housing is in a completely sealed state. Currently, the inflation time is manually controlled, and there is uncertainty in the control of the pressurization time, which may lead to the failure of the crystal oscillator sealing detection method.

[0048] In the technical solution defined by the present invention, on the one hand, automatic control is achieved, which is beneficial to reducing the labor intensity. On the other hand, the time relay is used to control the pressurization or pressure relief time of the pressure tank 210, solving the uncertainty of manual time control and greatly reducing the possibility of the failure of the crystal oscillator sealing detection method.

[0049] Embodiment 2

[0050] As Figure 1 shown, the control device 100 for detecting the sealing of electronic components further includes a start button 160. Specifically, the start button 160 is connected to the intermediate relay 150. By operating the start button 160, the switching of the intermediate relay 150 can be controlled, that is, the intermediate relay 150 can be selectively conducted with the first time relay 130 or the second time relay 140. Further, the start button 160 is connected to the first time relay 130. By operating the start button 160, the first time relay 130 can be enabled to control the inflation valve 110 to pressurize the pressure tank 210, and the pressurization time can also be set. Further, the start button 160 is connected to the second time relay 140. By operating the start button 160, the second time relay 140 can be enabled to control the deflation valve 120 to relieve the pressure of the pressure tank 210, and the pressure relief time can also be set.

[0051] In another embodiment, the control device 100 for detecting the sealing of electronic components further includes a counter 170. Specifically, the counter 170 is connected to the start button 160. By setting the counter 170, the start times of the start button 160 can be counted. Counting is the simplest basic operation. The counter 170 is a logic circuit that realizes this operation. The counter 170 mainly counts the number of pulses in the digital system to achieve the functions of measurement, counting, and control, and also has a frequency division function. The counter 170 is composed of basic counting units and some control gates, and the counting unit is composed of a series of flip-flops with the function of storing information.

[0052] Optionally, the counter 170 is used to count the number of pressurization times to more accurately understand the pressurization time, solve the uncertainty of manual time control, and can largely reduce the possibility of the failure of the crystal oscillator sealing detection means.

[0053] Embodiment III

[0054] As Figure 1 shown, the control device 100 for detecting the sealing performance of electronic components further includes a power supply 180. Specifically, the power supply 180 is connected to the intermediate relay 150. The intermediate relay 150 is used to conduct the power supply 180 to the first time relay 130 or conduct the power supply 180 to the second time relay 140. The intermediate relay 150 can selectively conduct to the first time relay 130 or the second time relay 140. It can be understood that the intermediate relay 150 is used to switch the circuit to control the pressure relief or pressurization of the pressure tank 210.

[0055] Furthermore, the control device 100 for detecting the sealing performance of electronic components further includes an air switch 190. Specifically, the air switch 190 is connected to the power supply 180, and the air switch 190 is connected to the intermediate relay 150. The air switch 190 is also known as an air circuit breaker and belongs to a type of circuit breaker. The air switch 190 is a switch that automatically disconnects as long as the current in the circuit exceeds the rated current. By adding the air switch 190, in addition to being able to complete the contact and disconnection of the circuit, it can also protect the circuit to avoid situations such as short circuit, serious overload, and undervoltage.

[0056] Embodiment IV

[0057] The first time threshold is 55 min to 65 min, that is, the time for the inflation valve 110 to inflate and pressurize the pressure tank 210 is 55 min to 65 min. Using the first time relay 130 to control the pressurization time of the pressure tank 210 solves the uncertainty of manual time control and can largely reduce the possibility of the failure of the crystal oscillator sealing detection means.

[0058] In another embodiment, the second time threshold is 10 s to 14 s, that is, the time for the deflation valve 120 to relieve the pressure of the pressure tank 210 is 10 s to 14 s. Using the second time relay 140 to control the pressure relief time of the pressure tank 210 also solves the uncertainty of manual time control and is beneficial to further reducing the possibility of the failure of the crystal oscillator sealing detection means.

[0059] Embodiment V

[0060] As Figure 1 and Figure 2As shown in the figure, a control device 100 for detecting the sealing performance of electronic components according to an embodiment of the present invention is composed of a start button 160, an air switch 190, an intermediate relay 150, a counter 170, a time relay, an inflation valve 110, and a deflation valve 120. The air switch 190 independently controls the power supply 180, the intermediate relay 150 switches auxiliary functions, the time relay controls the pressurization, inflation, and deflation time each time, the inflation valve 110 controls the inflation of the pressurization tank 210 in one direction each time, and the deflation valve 120 deflates in one direction after the pressurization time has elapsed. By controlling the pressurization time and automatically inflating and deflating through the time relay, the inflation valve 110, and the deflation valve 120, the stability of detecting the sealing performance of the crystal oscillator under pressure is improved, and the negligence of manual control is reduced.

[0061] Further, the air switch 190 independently controls the power supply 180, and the coil of the time relay is energized. The delayed opening contact works. Among them, the coil of the deflation valve 120 is energized for deflation for 12 seconds, and it resets after 12 seconds. By deflating at startup, it can ensure that the pressurization tank 210 can be opened normally. The counter 170 counts the number of pressurizations, and it accumulates once each time the start button 160 is pressed. The intermediate relay 150 switches the auxiliary function to a 220v intermediate relay 150. The coil of the intermediate relay 150 is energized, the normally closed contact opens for protection, and the deflation part does not work. The normally open contact is self-locked. The time relay controls the pressurization and inflation each time. The time relay is energized, and the delayed opening contact works, starting to count for 1 hour. Among them, the inflation valve 110 is energized and the inflation indicator light comes on. The time relay controls the pressurization, inflation, and deflation time each time. The first time relay 130 controls the pressurization and inflation time, and the second time relay 140 controls the deflation time. After 1 hour, the delayed contact opens, disconnecting the coil of the intermediate relay 150, the normally open contact opens, the self-locking is released, and the normally closed contact closes. The time relay coil's delayed opening contact works. After the coil of the deflation valve 120 is energized, it deflates the pressurization tank 210 for 12 seconds, and it resets after 12 seconds. There are a total of two groups of control devices 100 for detecting the sealing performance of electronic components, and the control methods are the same. The specific steps of the control method are as follows: First step, the second time relay 140 controls the deflation valve 120 to relieve the pressure of the pressurization tank 210, which is convenient for opening and placing the component to be detected into the pressurization tank 210; Second step, the first time relay 130 controls the inflation valve 110 to pressurize the pressurization tank 210 to detect the component to be detected; Third step, the second time relay 140 controls the deflation valve 120 to relieve the pressure of the pressurization tank 210, which is convenient for opening and taking out the component to be detected from the pressurization tank 210.

Specifically, the inflation valve 110 of the control device 100 for detecting the airtightness of an electronic component is connected to the pressure tank 210, and the inflation valve 110 can pressurize the pressure tank 210. The deflation valve 120 of the control device 100 for detecting the airtightness of an electronic component is connected to the pressure tank 210, and the deflation valve 120 can relieve the pressure of the pressure tank 210. The control process specifically includes: First step, the second time relay 140 controls the deflation valve 120 to relieve the pressure of the pressure tank 210, which is convenient for opening and putting the component to be detected into the pressure tank 210; Second step, the first time relay 130 controls the inflation valve 110 to pressurize the pressure tank 210 to detect the component to be detected; Third step, the second time relay 140 controls the deflation valve 120 to relieve the pressure of the pressure tank 210, which is convenient for opening and taking out the component to be detected from the pressure tank 210.

[0064] It should be noted that the number of the control devices 100 for detecting the airtightness of an electronic component is at least one. Considering factors such as the occupied space size, the efficiency of inflating / pressurizing or deflating / relieving the pressure of the pressure tank 210, and other factors, the control devices 100 for detecting the airtightness of an electronic component are flexibly set according to actual needs. The pressure tank 210 is used to place the component to be detected.

[0065] In another embodiment, the number of the control devices 100 for detecting the airtightness of an electronic component is two. By setting the number to two, it can be understood that there are two sets of control systems in total, and the control methods are the same. While ensuring that the occupied space will not be too large, it is beneficial to improve the efficiency of inflating / pressurizing or deflating / relieving the pressure of the pressure tank 210, and achieve precise control of the pressurizing and pressure-relieving times.

[0066] According to the embodiments of the control device and the detection device for detecting the airtightness of an electronic component of the present invention, on the one hand, automatic control is realized, which is beneficial to reducing the labor intensity; on the other hand, the time for pressurizing or relieving the pressure of the pressure tank is controlled by a time relay, which solves the uncertainty of manual time control, and to a great extent, can reduce the possibility of the failure of the crystal oscillator airtightness detection means.
