[0002] In the production process of socket products, it is usually necessary to assemble various parts. In some assembly processes, various types of socket products need to be pressed manually to ensure that the assembled parts and the socket product body are tight enough, thereby avoiding the production of socket products with loose structure or poor electrical properties.

[0003] However, since the pressing action is usually implemented manually, it is easy to miss pressing or not pressing the socket product to the right position, and such socket products are difficult to be controlled by subsequent visual inspection processes. Invention content

[0017] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0018] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0019] This application presents a socket pressing detection device according to a first embodiment. Please refer to [link / reference]. Figure 1 The socket press detection equipment includes:

[0020] The data acquisition device 10 is electrically connected to the input terminal of the analog-to-digital converter circuit 20. It is used to acquire the maximum pressure value applied to the preset socket 50 when the preset socket 50 is pressed, and output the corresponding pressure acquisition signal to the analog-to-digital converter circuit 20.

[0021] The analog-to-digital converter circuit 20 is also electrically connected to the input terminal of the main control circuit 30, and is used to convert the received pressure acquisition signal into a digital pressure signal and serially transmit the digital pressure signal to the main control circuit 30.

[0022] The main control circuit 30 is used to electrically connect to the communication terminal of the host computer 40. When the maximum pressure value corresponding to the digital pressure signal is detected to be not less than the preset pressure threshold corresponding to the pressure setting signal transmitted by the host computer 40, the main control circuit 30 feeds back a test qualified signal to the host computer 40.

[0023] It should be understood that, in this embodiment, the socket pressing detection device is applied to the production scenario of socket products, specifically to the production process of pressing socket products. The preset socket 50 is the semi-finished socket product to be produced. Components are mounted on the surface of the preset socket 50, and these components need to be pressed to ensure tight assembly between the components and the main body of the preset socket 50.

[0024] It should be noted that, in this embodiment, the pressure data acquisition device 10 is a device with pressure acquisition and pressure transmission functions. The user can press the area to be pressed on the preset socket 50 using the pressure data acquisition device 10. Since forces are mutual, the reaction force corresponding to the pressure applied to the preset socket 50 by the pressure data acquisition device 10 will be transmitted through its internal structure. Therefore, the pressure currently applied to the preset socket 50 can be determined by acquiring the reaction force transmitted through the internal structure. Correspondingly, the pressure data acquisition device 10 can generate a pressure acquisition signal with a corresponding voltage value based on the acquired pressure and transmit the pressure acquisition signal to the analog-to-digital conversion circuit 20.

[0025] It is easy to understand that the pressure acquisition signal is an analog electrical signal. In this embodiment, the voltage value of the generated pressure acquisition signal is directly proportional to the acquired pressure value; that is, the higher the pressure value, the higher the voltage value of the pressure acquisition signal. Therefore, when the voltage value of the pressure acquisition signal reaches its maximum, it can be considered that the currently acquired pressure has reached its maximum, i.e., the maximum pressure value mentioned above.

[0026] It should be noted that the digital pressure signal is a digital electrical signal. In this embodiment, the analog-to-digital converter 20 can digitize the pressure acquisition signal, converting the analog pressure acquisition signal into a digital pressure signal, and then serially transmitting the digital pressure signal to the main control circuit 30.

[0027] It should be understood that the pressure setting signal refers to a digital electrical signal generated by user-defined triggering. The digital quantity it expresses can be used to characterize a specific pressure value, namely the aforementioned preset pressure threshold. The preset pressure threshold is a set pressure value used to determine whether the preset socket 50 has been pressed into place. In this embodiment, the main control circuit 30 also communicates with the host computer 40, and the two can exchange information. Specifically, the host computer 40 can generate a pressure setting signal through user triggering and serially transmit the pressure setting signal to the main control circuit 30.

[0028] It should be noted that, in this embodiment, the main control circuit 30 can determine the digital value corresponding to the preset pressure threshold set by the user when it receives the pressure setting signal. Simultaneously, the main control circuit 30 can also determine the digital value of the maximum pressure currently applied to the preset socket 50 when it receives the digital pressure signal. Subsequently, the main control circuit 30 compares the digital value represented by the pressure setting signal with the digital value represented by the digital pressure signal to determine whether the pressure received by the preset socket 50 meets the pressing requirement, thereby determining whether the preset socket 50 has undergone an effective pressing process.

[0029] It should be understood that, in this embodiment, during the pressing of the preset socket 50, in the initial stage of pressing the preset socket 50, since the installed component is not fully inserted into the body of the preset socket 50, the pressure applied to the preset socket 50 by the pressure data acquisition device causes the component to slide towards the body of the preset socket 50. At this time, the pressure on the preset socket 50 is approximately equivalent to the sliding friction between the component and the body of the preset socket 50, and the sliding friction is relatively small. However, in the completion stage of pressing the preset socket 50, since the component has been fully inserted into the body of the preset socket 50, the component can no longer slide into the body of the preset socket 50. Therefore, the pressure applied to the preset socket 50 by the pressure data acquisition device is equivalent to the reaction force fed back from the body of the preset socket 50 to the pressure data acquisition device, and the reaction force is relatively large.

[0030] It is easy to understand that a test pass signal is an electrical signal used to indicate that the maximum pressure value of the currently collected pressure exceeds a preset pressure threshold, while a test failure signal is an electrical signal used to indicate that the maximum pressure value of the currently collected pressure does not exceed the preset pressure threshold. In this embodiment, when the main control circuit 30 detects that the maximum pressure value corresponding to the currently received digital pressure signal is not less than the preset pressure threshold corresponding to the currently received pressure setting signal, it can determine that the current component has been tightly combined with the body of the preset socket 50, and then generates the corresponding test pass signal and transmits the test pass signal to the host computer 40 to indicate that the current preset socket 50 has been pressed into place; when the main control circuit 30 detects that the maximum pressure value corresponding to the currently received digital pressure signal is less than the preset pressure threshold corresponding to the currently received pressure setting signal, it can determine that the current component has not been tightly combined with the body of the preset socket 50, and then generates the corresponding test failure signal and transmits the test failure signal to the host computer 40 to indicate that the current preset socket 50 has not been pressed or has not been pressed into place. Users can easily and accurately determine whether the current preset socket 50 has been effectively pressed by checking whether the signal received by the host computer 40 is a test pass signal or a test failure signal, without any misjudgment.

[0031] It is worth noting that, in this embodiment, as a specific approach, to improve the accuracy of the test pass signal, the preset pressure threshold corresponding to the pressure setting signal should be much higher than the aforementioned sliding friction force. However, it should be noted that if the pressure applied to the preset socket 50 is too large, it may damage the hardware structure of the preset socket 50; therefore, the preset pressure threshold should not be set too high.

[0032] This application provides a socket pressing detection device, which includes a pressing data acquisition device, an analog-to-digital conversion circuit, and a main control circuit. The analog-to-digital conversion circuit is electrically connected to both the pressing data acquisition device and the main control circuit, and the main control circuit is also electrically connected to a host computer. In the pressing process of the socket production process, the user uses the pressing data acquisition device to press a preset socket. When pressing the preset socket, the pressing data acquisition device acquires the maximum pressure value applied to the preset socket, thereby generating a corresponding pressure acquisition signal. The analog-to-digital conversion circuit converts the pressure acquisition signal into an analog-to-digital signal and transmits the corresponding digital pressure signal to the main control circuit. When the maximum pressure value corresponding to the digital pressure signal is not less than the preset pressure threshold corresponding to the pressure setting signal transmitted by the host computer, the main control circuit feeds back a test pass signal to the host computer, indicating that the preset socket has undergone an effective pressing process.

[0033] Based on the first embodiment of the socket pressing detection device of this application, in the second embodiment of the socket pressing detection device of this application, the content that is the same as or similar to that in the first embodiment can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 The analog-to-digital converter circuit 20 includes: a first resistor R1, a second resistor R2, a first capacitor C1, and an analog-to-digital converter chip U1;

[0034] The first differential input pin of the analog-to-digital converter chip U1 is connected to the second end of the first resistor R1 and the first end of the first capacitor C1, respectively. The second differential input pin of the analog-to-digital converter chip U1 is connected to the second end of the second resistor R2 and the second end of the first capacitor C1, respectively. The first end of the first resistor R1 and the first end of the second resistor R2 are used to be electrically connected to the output end of the press data acquisition device 10.

[0035] The serial output pin and clock pin of the analog-to-digital converter chip U1 are used for electrical connection with the main control circuit 30.

[0036] It should be noted that in this embodiment, the analog-to-digital converter chip U1 may have a differential input structure, receiving analog pressure acquisition signals from the pressure data acquisition device through a first differential input pin and a second differential input pin. Specifically, the first resistor R1 and the second resistor R2 serve as current-limiting resistors for the two differential input pins, preventing excessive current from damaging the pins; the first capacitor C1 serves as a filter capacitor between the two differential input pins, filtering out differential-mode interference in the transmission line to ensure more accurate pressure values ​​are acquired.

[0037] It is easy to understand that in this embodiment, the analog-to-digital converter chip U1 integrates a clock unit, which can operate based on the clock provided by the clock unit. The analog-to-digital converter chip U1 can convert the received differential pressure acquisition signal into a serial digital signal, namely the aforementioned digital pressure signal. Subsequently, the analog-to-digital converter chip U1 can transmit its internal clock to the main control circuit 30, enabling data transmission between the two circuits and allowing the digital pressure signal to be serially output to the main control circuit 30 in a specific timing sequence. As a specific embodiment, the analog-to-digital converter chip U1 can be an HX711 chip.

[0038] Furthermore, in this embodiment, the analog-to-digital conversion circuit 20 further includes: a third resistor R3 to a fifth resistor R5, a second capacitor C2 to a fifth capacitor C5, a first inductor L1, and a first P-type transistor Qp1;

[0039] The second end of the third resistor R3 is connected to the voltage regulation control pin of the analog-to-digital converter chip U1. The first end of the third resistor R3 is connected to the base of the first P-type transistor Qp1. The collector of the first P-type transistor Qp1 is connected to the first end of the second capacitor C2 and the second end of the first inductor L1. The second end of the second capacitor C2 is grounded. The emitter of the first P-type transistor Qp1 is connected to the analog power supply pin of the analog-to-digital converter chip U1, the first end of the fourth resistor R4, and the first end of the third capacitor C3. The feedback input pin of the analog-to-digital converter chip U1, the second end of the fourth resistor R4, the first end of the fifth resistor R5, the second end of the third capacitor C3, and the first end of the fourth capacitor C4 are grounded. The second end of the fifth resistor R5 is connected to the analog ground pin of the analog converter chip. The second end of the fourth capacitor C4 is connected to the voltage regulation output pin of the analog-to-digital converter chip U1. The first end of the first inductor L1 is connected to the digital power supply pin of the analog-to-digital converter chip U1, the first end of the fifth capacitor C5, and the preset power supply VDD. The second end of the fifth capacitor C5 is grounded.

[0040] It should be noted that, in this embodiment, to ensure the operational stability of the analog-to-digital converter chip U1, a linear voltage regulator unit is also provided inside the chip. This linear voltage regulator unit further constructs a feedback circuit through a third resistor R3, a fourth resistor R4, a fifth resistor R5, a second capacitor C2, a third capacitor C3, a fourth capacitor C4, a fifth capacitor C5, a first inductor L1, and a first P-type transistor Qp1. This enhances the analog-to-digital converter chip U1's ability to suppress power supply noise, ensuring the output of a high-precision, stable digital pressure signal.

[0041] It is easy to understand that in this embodiment, the first inductor L1 and the second capacitor C2 are connected in series between the preset power supply VDD and the ground line to form an LC filter network. This network is used to prevent high-frequency noise provided by the preset power supply VDD from flowing into the feedback circuit, thereby improving the circuit's electromagnetic interference resistance. The third resistor R3 is placed between the base of the first P-type transistor Qp1 and the voltage regulation control pin of the analog-to-digital converter chip U1 to limit current and protect the pin and the first P-type transistor Qp1 from damage due to excessive current. The fourth resistor R4 and the fifth resistor R5 form a series voltage divider structure to form a feedback sampling network. This network can provide the feedback voltage formed by the voltage divider to the feedback input pin of the analog-to-digital converter chip U1, so that the error amplifier inside the analog-to-digital converter chip U1 compares it with an extremely stable reference voltage generated internally (corresponding to the voltage provided by the voltage regulation output pin of the analog-to-digital converter chip U1), thereby adaptively adjusting the voltage at the voltage regulation control pin. In this way, the operating voltage received by the analog power input pin can be dynamically adjusted by adjusting the amplification gain of the first P-type transistor Qp1, thereby ensuring the stability of the operating voltage and thus ensuring the operating stability of the analog-to-digital converter chip U1.

[0042] It should be noted that in this embodiment, the fifth capacitor C5 is connected between the preset power supply VDD and the ground line, which also serves to filter the input power supply and prevent high-frequency noise provided by the preset power supply VDD from flowing into the digital power supply pin of the analog-to-digital converter chip U1; the third capacitor C3 can be used as a filter capacitor between the analog power supply pin and the analog ground pin, and can also provide transient current to the linear voltage regulator unit inside the analog-to-digital converter chip U1 when it is operating and performing high-speed switching, so as to make it work stably; the fourth capacitor C4 is a decoupling capacitor set between the voltage regulator output pin and the ground line, which is used to ensure that the reference voltage provided by the voltage regulator output pin remains stable, so as to ensure the working stability of the internal linear voltage regulator unit, and thus ensure the working stability of the entire analog-to-digital converter chip U1.

[0043] Furthermore, in this embodiment, the main control circuit 30 includes: a control chip U2 and a serial communication circuit 31;

[0044] The input terminal of the control chip U2 is electrically connected to the output terminal of the analog-to-digital converter circuit 20, and the communication terminal of the control chip U2 is electrically connected to the first terminal of the serial communication circuit 31. The second terminal of the serial communication circuit 31 is used to electrically connect to the communication terminal of the host computer 40.

[0045] The serial communication circuit 31 is used to serially transmit the pressure setting signal provided by the host computer 40 to the control chip U2 after level conversion;

[0046] The control chip U2 is used to send a test pass signal to the serial communication circuit 31 when the maximum pressure value corresponding to the digital pressure signal is not less than the preset pressure threshold corresponding to the pressure setting signal.

[0047] The serial communication circuit 31 is used to serially transmit the test pass signal to the host computer 40 after level conversion.

[0048] It should be noted that, in this embodiment, the control chip U2 can specifically be a microcontroller with multiple interfaces such as I / O ports and serial ports, such as the ATMEGA2560 chip. It can be electrically connected to the analog-to-digital converter circuit 20 through a pair of communication interfaces with clock transmission function, and can communicate with the serial communication circuit 31 through another pair of serial ports.

[0049] In this embodiment, the serial communication circuit 31 converts the pressure setting signal provided by the host computer 40 into an electrical signal whose voltage can be recognized by the control chip U2, and then transmits it serially to the control chip U2. Upon receiving the pressure setting signal after level conversion, the control chip U2 determines the digital value of the preset pressure threshold corresponding to the pressure setting signal. Simultaneously, the control chip U2 can also directly receive the digital pressure signal provided by the analog-to-digital converter 20 and determine the digital value of the maximum pressure value corresponding to the digital pressure signal. Subsequently, the control chip U2 compares the two data values, and when it detects that the digital value of the maximum pressure value corresponding to the digital pressure signal is not less than the digital value of the preset pressure threshold corresponding to the pressure setting signal, it generates a test pass signal indicating that the current preset socket 50 has undergone a valid pressing process, and transmits it to the serial communication circuit 31. The serial communication circuit 31 performs level conversion on the test pass signal, converting it into an electrical signal whose voltage can be recognized by the host computer 40, and then transmits it serially to the host computer 40.

[0050] Furthermore, in this embodiment, the serial communication circuit 31 includes: a sixth capacitor C6, a seventh capacitor C7, an eighth capacitor C8, and a serial port chip U3.

[0051] The first power supply pin of serial port chip U3 is connected to the first terminal of the sixth capacitor C6 and the preset power supply VDD, respectively. The ground pin of serial port chip U3 and the second terminal of the sixth capacitor C6 are grounded. The second power supply positive pin of serial port chip U3 is connected to the preset power supply VDD and the first terminal of the seventh capacitor C7, respectively. The second terminal of the seventh capacitor C7 is grounded. The second power supply negative pin of serial port chip U3 and the second terminal of the eighth capacitor C8 are grounded. The first terminal of the eighth capacitor C8 is connected to the preset power supply VDD.

[0052] The first communication group pin of serial port chip U3 is connected to the communication terminal of control chip U2, and the second communication group pin of serial port chip U3 is connected to the communication terminal of host computer 40.

[0053] It should be noted that the serial communication circuit 31 is specifically a serial communication circuit 31 capable of implementing the RS232 communication protocol, and its internal serial port chip U3 can specifically be a MAX232IDR chip. In this embodiment, the serial port chip U3 includes a first communication group pin and a second communication group pin, which are respectively used to connect the communication terminal of the control chip U2 and the communication terminal of the host computer 40. The serial port chip U3 can also perform level conversion. For the control chip U2 side, the first power supply pin of the serial port chip U3 can be connected to a preset power supply VDD that can provide a recognizable voltage for the control chip U2; for the host computer 40 side, the second power supply positive pin of the serial port chip U3 is connected to the preset power supply VDD, and the second power supply negative pin is connected to ground. Based on the above structure, the voltage of the signal transmitted between the host computer 40 and the control chip U2 can always be within the voltage range recognizable by the receiver after level conversion.

[0054] It is easy to understand that in this embodiment, the sixth capacitor C6 is located between the first power supply pin and the ground pin of the serial port chip U3, and is used to filter the power input on the control chip U2 side; the seventh capacitor C7 is located between the second power supply positive pin and the ground line, and the eighth capacitor C8 is located between the second power supply negative pin and the preset power supply VDD, and the two are used together to filter the power input on the host computer 40 side.

[0055] Based on the first and / or second embodiments of the socket pressing detection device of this application, in the third embodiment of the socket pressing detection device of this application, the content that is the same as or similar to the above-described embodiments one and two can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 In this embodiment, the socket press detection device further includes a display device 60;

[0056] The display device 60 is electrically connected to the main control circuit 30;

[0057] The main control circuit 30 is also used to transmit the received digital pressure signal to the display device 60 so that the display device 60 displays the corresponding maximum pressure value;

[0058] The main control circuit 30 is also used to transmit the received pressure setting signal to the display device 60 so that the display device 60 displays the corresponding preset pressure threshold.

[0059] It should be noted that, in this embodiment, the display device 60 can be any one of a digital tube display screen, a liquid crystal display screen, or other electronic products capable of displaying numerical values.

[0060] It is easy to understand that in this embodiment, the main control circuit 30 can directly transmit the pressure setting signal provided by the host computer 40 or the digital pressure signal provided by the analog-to-digital conversion circuit 20 to the display device 60. The display device 60 can display the digital value of the maximum pressure corresponding to the digital pressure signal when it receives the digital pressure signal, and it can also display the digital value of the preset pressure threshold corresponding to the pressure setting signal when it receives the pressure setting signal. This configuration facilitates the operator's confirmation of whether the pressing process on the preset socket 50 is effective, that is, whether the action on the preset socket 50 is in place.

[0061] Furthermore, in this embodiment, the pressure data acquisition device 10 includes: a pressure sensor 11 and a triggering mechanism for triggering the pressure sensor 11;

[0062] The triggering mechanism includes: a pressure rod 12, a first fixing structure 13, a second fixing structure 14, and a housing 15;

[0063] The pressure bar 12 is disposed inside the outer shell 15. The first end of the outer shell 15 is provided with a first fixing structure 13, and the second end of the outer shell 15 is provided with a second fixing structure 14.

[0064] The first end of the pressure bar 12 has an exposed area, which is exposed through the first fixing structure 13, and the end of the exposed area is used to press the preset socket 50.

[0065] The first fixing structure 13, the second fixing structure 14, and the outer shell 15 are used to limit the movement range of the pressure bar 12 so that the non-exposed area of ​​the pressure bar 12 can move between the first fixing structure 13 and the second fixing structure 14.

[0066] The pressure sensor 11 is disposed on the pressure bar 12 or the second fixed structure 14, and is located between the pressure bar 12 and the second fixed structure 14, and is electrically connected to the input terminal of the analog-to-digital conversion circuit 20.

[0067] It should be noted that, in this embodiment, specific reference is made. Figure 4 , Figure 4The electrical connections of the pressure sensor 11 are not shown, but it should be understood that the pressure sensor 11 is electrically connected to the input terminal of the analog-to-digital converter. The pressure data acquisition function of the pressure data acquisition device 10 can be realized through the pressure sensor 11, while the pressure transmission function of the pressure data acquisition device 10 can be realized through a trigger mechanism physically connected to the pressure sensor 11.

[0068] It is readily understood that, in this embodiment, specific references are made. Figure 4 The triggering mechanism is mainly composed of a first fixing structure 13, a housing 15, and a second fixing structure 14, and its overall shape can be pen-shaped. The first fixing structure 13 can be fixed to the first end of the housing 15, and the second fixing structure 14 can be fixed to the second end of the housing 15. Inside these three structures is a movable pressure rod 12. The first fixing structure 13 has holes, allowing a portion of the pressure rod 12 to pass through and be exposed. Therefore, the pressure rod 12 can also be divided into an exposed area that can be exposed to the housing 15, the first fixing structure 13, and the second fixing structure 14, and a non-exposed area that cannot be exposed.

[0069] It should be noted that in this embodiment, the non-exposed area of ​​the pressure bar 12 is wider than the exposed area and cannot pass through the aforementioned hole. Therefore, the first fixing structure 13 and the second fixing structure 14 can ensure that the non-exposed area of ​​the pressure bar 12 cannot move to the outside, thereby restricting the movement range of the non-exposed area of ​​the pressure bar 12, so that the entire pressure bar 12 can only move in a straight line in the straight line direction formed by the first fixing structure 13 and the second fixing structure 14, and the non-exposed area is always located between the two.

[0070] It is readily understood that, in this embodiment, the pressure sensor 11 can be specifically disposed at the end of the non-exposed area of ​​the pressure bar 12 or on the side of the second fixing structure 14 near the pressure bar 12. Thus, when the user controls the pressure data acquisition device 10 to press the preset socket 50, the preset socket 50 will apply an equal-value reaction force to the pressure bar 12. This reaction force is transmitted through the pressure bar 12 to the pressure sensor 11, thereby allowing the pressure applied to the preset socket 50 to be collected.

[0071] Furthermore, to achieve the above objectives, embodiments of this application also propose a socket press detection system, such as... Figure 5 As shown, the socket press detection system includes: a host computer 40 and all embodiments of the aforementioned socket press detection equipment.

[0072] Furthermore, in this embodiment, the socket press detection system also includes a barcode scanning device 70;

[0073] The barcode scanning device 70 is electrically connected to the host computer 40;

[0074] The barcode scanning device 70 is used to collect the preset product code of the preset socket 50 and send the corresponding product code signal to the host computer 40.

[0075] The host computer 40 is used to bind the preset product code with the press test qualified mark when it receives the product code signal and the test qualified signal sent by the socket press test device.

[0076] It should be understood that the preset product code is the production number of the preset socket 50. The two correspond one-to-one and are mainly used to trace its production process. They can also be used to identify production information such as the manufacturer.

[0077] It is easy to understand that the press test pass indicator is a corresponding indicator generated by the host computer 40 based on the received test pass signal, and the press test failure indicator is a corresponding indicator generated by the host computer 40 based on the received test failure signal. In this embodiment, after each preset socket 50 completes the press test, the socket press detection device will output a test pass signal (when the maximum pressure value corresponding to the detected data pressure signal is not less than the preset pressure threshold corresponding to the pressure setting signal) or a test failure signal (when the maximum pressure value corresponding to the detected data pressure signal is less than the preset pressure threshold corresponding to the pressure setting signal).

[0078] It should be noted that in this embodiment, the host computer 40 may also be equipped with a barcode scanning device 70. Before pressing any preset socket 50, the barcode scanning device 70 can collect the preset product code corresponding to a preset socket 50, generate a corresponding digital product code signal, and transmit it to the host computer 40. After receiving the product code signal, the host computer 40 can confirm which preset socket 50 is currently being pressed. Subsequently, the socket pressing detection device normally determines the result of the current pressing test, i.e., whether it received a test pass signal or a test failure signal. If the host computer 40 receives a test pass signal, it will bind the preset product code of the current preset product with the pressing test pass identifier corresponding to the test pass signal to indicate that the preset product has undergone a valid pressing process; if the host computer 40 receives a test failure signal, it will bind the preset product code of the current preset product with the pressing test failure identifier corresponding to the test failure signal to indicate that the preset product has not undergone a valid pressing process, i.e., there is a possibility that the pressing is incomplete, and the pressing process needs to be repeated.

[0079] This design allows for the direct determination of whether the current preset socket 50 has undergone a valid pressing process by reading the preset product code of the preset socket 50 during subsequent production processes. This automatically determines whether the preset socket 50 needs to be reworked, effectively preventing defective products from being released. It also reduces the time required for subsequent rework (the earlier the process of identifying defective products is initiated, the fewer rework processes are required, and the less time is spent on rework).

[0080] The beneficial effects of the socket pressing detection system provided in this application embodiment are the same as those of the socket pressing detection device provided in the above embodiment, and can solve the technical problem of how to accurately determine whether the socket has undergone an effective pressing process during the production process.

[0081] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent scope of this application.
