The first figure is a control principle structure block diagram of an electronic device pin length measuring device provided in the first embodiment of the present invention, and the second figure is a measurement structure schematic diagram of an electronic device pin length measuring device provided in the first embodiment of the present invention. Referring to the first figure and the second figure, the electronic device pin length measuring device includes: a measurement sensing module 100, a motor 200, a first support frame 300, a second support frame 400, a control module 500, a display module 600 and an alarm module 700; wherein the motor 200, the measurement sensing module 100, the display module 600 and the alarm module 700 are all electrically connected to the control module 500; wherein the motor 200 is fixedly arranged on the first support frame 300. The electronic device 10 to be tested is fixedly arranged at a first preset position X1 of the first support frame 300; the motor 200 includes a motor output screw 201, and at least one second support frame 400 is horizontally fixedly arranged on the motor output screw 201; a measuring sensing module 100 is fixedly arranged at a second preset position X2 of the second support frame 400; wherein the orthographic projections of the first preset position X1 and the second preset position X2 in the vertical direction Y are overlapped; the electronic device 10 to be tested is fixedly arranged at a first preset position X1 of the first support frame 300; The pin of the electronic device 10 is located between the first preset position X1 and the second preset position X2 in the vertical direction Y; wherein the measuring sensing module 100 is used to feedback the position sensing signal to the control module 500 when the distance from the pin of the electronic device 10 to be tested is preset; the control module 500 is configured to: control the motor 200 to rotate according to the measurement start instruction to drive the measuring sensing module 100 to move from the initial position to the pin of the electronic device 10 to be tested; upon receiving the position sensing signal When the signal is received, the control motor 200 stops rotating to stop the measuring sensing module 100, and the stop position of the measuring sensing module 100 is obtained; the length of the pin of the electronic device 10 to be tested is determined according to the initial position and the stop position, and it is judged whether the length of the pin of the electronic device 10 to be tested meets the preset condition; if it meets the preset condition, the length of the pin of the electronic device 10 to be tested is sent to the display module 600 for display; if it does not meet the preset condition, an alarm signal is generated to the alarm module 700.

Referring to the first figure, the measuring sensing module 100, the motor 200, the display module 600 and the alarm module 700 are all electrically connected to the control module 500. Among them, the motor 200 can be a stepper motor or a servo motor, and accordingly, a stepper motor driver or a servo motor driver corresponding to the motor can be configured. The specific motor model and driver model can be set according to the actual situation and are not specifically limited here.

The control module 500 may be a single chip microcomputer, a PLC or other controller, and may be configured according to actual conditions, and is not specifically limited here.

The display module 600 may be a display device such as a human-machine interface, which is used to display information such as the measurement results of the electronic device to be tested, and to facilitate the user to set various parameters, etc. For example, a measurement start button may be provided on the human-machine interface, and the measurement start button is electrically connected to the control module 500. When the lead length measurement is required, the user may click the measurement start button on the human-machine interface, and after clicking, the control module 500 will receive the measurement start instruction and start the measurement operation according to the instruction.

Among them, the alarm module 700 can be a sound alarm, a sound and light alarm, a light alarm, etc., and can be set according to the actual situation, and no specific limitation is made here.

Referring to the second figure, the motor 200 is fixedly mounted on the first support frame 300, and the motor 200 includes a motor output screw 201, and the second support frame is horizontally fixedly mounted on the motor output screw 201. When the motor 200 rotates (forward or reverse), the motor output screw 201 is driven to rotate, and the second support frame 400 is driven to rise or fall accordingly. Since the measuring sensing module 100 is fixedly mounted at the second preset position X2 of the second support frame 400, the measuring sensing module 100 will also rise or fall along with the second support frame 400.

Continuing to refer to the second figure, the electronic device to be tested 10 is fixedly set at the first preset position X1 of the first support frame 300. When the measuring sensing module 100 moves upward along with the second support frame 400 (i.e., approaches the pins of the electronic device to be tested) and moves to a preset distance position from the pins of the electronic device to be tested, it will sense the pins of the electronic device to be tested 10. At this time, the measuring sensing module 100 will feedback the position sensing signal to the control module 500.

For example, referring to the second figure, the orthographic projections of the first preset position X1 and the second preset position X2 in the vertical direction Y overlap. The end of the pin of the electronic device 10 to be tested is located between the first preset position X1 and the second preset position X2 in the vertical direction Y.

For example, the motor 200 is a stepper motor and the display module 600 is a human-machine interface. In the technical solution of this embodiment, the implementation process of the electronic device lead length measuring device is as follows: In combination with the first figure and the second figure, when it is necessary to measure the lead length of the electronic device 10 to be tested, the user clicks the measurement start button of the human-machine interface. After clicking, the control module 500 receives the measurement start instruction and controls the motor 500 according to the measurement start instruction. The motor 200 rotates to drive the measuring sensing module 100 to move upward from the initial position (assuming that it is the x0 position in the second figure), that is, to move in the direction close to the pin (end) of the electronic device 10 to be tested. When the measuring sensing module 100 moves to a preset distance from the end of the pin of the electronic device 10 to be tested (such as the y1 position in the second figure), it will sense the pin of the electronic device 10 to be tested and at the same time feedback the position sensing signal to the control module 500. After receiving the position sensing signal, the control module 500 controls the motor 200 to stop rotating, so that the measuring sensing module 100 stops moving, and obtains the stop position of the measuring sensing module 100 (such as the x1 position in the second figure). Then, the control module 500 can calculate the length of the pin of the electronic device 10 to be tested according to the initial position x0, the stop position x1, the preset distance y1, and the fixed position x2 of the initial end of the pin of the electronic device to be tested (this is a known quantity, and the specific value can be determined according to the actual installation setting). After calculating the length of the pin of the electronic device 10 to be tested, it is determined whether the length of the pin of the electronic device 10 to be tested meets the preset conditions. If it meets the conditions, the length of the pin of the electronic device 10 to be tested is sent to the display module 600 for display, so as to facilitate the reference of relevant personnel. Otherwise, an alarm signal is generated and sent to the alarm module 700, and the alarm module 700 sends an alarm message to prompt relevant personnel to handle it. It can be seen that the electronic device lead length measuring device can realize automatic measurement of the length of the electronic device lead to be measured, and compared with the existing manual auxiliary instrument measurement method, it can avoid the problem of poor measurement accuracy caused by frequent manual caliper measurement that cannot be accurately controlled at all times. It can also greatly reduce the manual workload and load, ensure product quality and improve production efficiency.

In addition, the pin length measurement result of the electronic device 10 to be tested calculated by the control module 500 can also be bound to the MEMS system of the production line of the electronic device to be tested, that is, sent to the MEMS system. If the measurement result meets the requirements of the production line, the production of the next electronic device to be tested will continue. Otherwise, if it does not meet the requirements, it will be replaced.

The technical solution of this embodiment provides an electronic device lead length measuring device, which includes: a measuring sensing module, a motor, a first support frame, a second support frame, a control module, a display module and an alarm module; wherein the motor, the measuring sensing module, the display module and the alarm module are all electrically connected to the control module; wherein the motor is fixedly arranged on the first support frame; the electronic device to be measured is fixedly arranged at a first preset position of the first support frame; the motor includes a motor output screw, and at least one second support frame is horizontally fixedly arranged on the motor output screw; a measuring sensing module is fixedly arranged at a second preset position of the second support frame; wherein the orthographic projections of the first preset position and the second preset position in the vertical direction overlap; the pin of the electronic device to be measured is fixedly arranged at a first preset position of the first support frame; The measuring sensing module is located between a first preset position and a second preset position in the vertical direction; wherein the measuring sensing module is used to feed back a position sensing signal to the control module when the measuring sensing module is at a preset distance from the pin of the electronic device to be tested; the control module is configured to: control the motor to rotate according to a measurement start instruction to drive the measuring sensing module to move from an initial position to the pin of the electronic device to be tested; control the motor to stop rotating when receiving the position sensing signal to stop the measuring sensing module from moving, and obtain the stop position of the measuring sensing module; determine the length of the pin of the electronic device to be tested according to the initial position and the stop position, and judge whether the length of the pin of the electronic device to be tested meets the preset conditions; if so, send the length of the pin of the electronic device to be tested to the display module for display; if not, generate an alarm signal to the alarm module. It can be seen that the electronic device lead length measuring device can realize automatic measurement of the electronic device lead length, improve measurement accuracy and production efficiency, and reduce manual workload and costs.

On the basis of the above-mentioned technical implementation scheme, optionally, the control module is also configured to: when sending the length of the pin of the electronic device to be tested to the display module for display, it is also used to control the motor to rotate in the opposite direction to return the measuring sensing module to the initial position.

When the motor drives the second support frame to move upward (i.e., move toward the end of the pin of the electronic device to be tested), the motor can be set to rotate in the forward direction. Correspondingly, when the motor drives the second support frame to move downward (i.e., move away from the end of the pin of the electronic device to be tested), the motor can be set to rotate in the reverse direction. In addition, the reverse setting can also be made, which can be made according to the actual situation and is not specifically limited here.

Specifically, when the control module determines that the length of the pin of the electronic device to be tested meets the preset conditions, it will send the length of the pin of the electronic device to be tested to the display module for display, and at the same time control the motor to rotate in the opposite direction to drive the measuring sensing module to move downward (i.e., move away from the end of the pin of the electronic device to be tested), so that the measuring sensing module returns to the initial position and waits for the next measurement.

Optionally, the preset condition is: whether the length of the pin of the electronic device to be tested does not exceed the preset length range.

The preset length range includes an upper limit value and a lower limit value. Exceeding the preset length range includes exceeding the upper limit value and the lower limit value. The specific upper and lower limits of the preset length range can be set according to actual conditions and are not specifically limited here.

Specifically, after calculating the pin length of the electronic device to be tested, the control module determines whether the length of the pin of the electronic device to be tested does not exceed the preset length range. If it does not exceed, the length of the pin of the electronic device to be tested is sent to the display module for display to facilitate the reference of relevant personnel. If it exceeds (it may exceed the upper limit or lower limit of the preset length range), an alarm signal is generated and sent to the alarm module, and the alarm module issues an alarm message to prompt relevant personnel to handle it.

Optionally, the pin type of the electronic device includes metal pins and non-metal pins; the measuring sensing module includes an inductive proximity switch sensor and a capacitive proximity switch sensor.

Among them, setting it not to directly contact the end of the pin of the electronic device to be tested can avoid damaging the end of the pin of the electronic device to be tested due to rising movement. Correspondingly, the preset distance can be set to 0, or it can be set to a value such as 2 mm, 5 mm, etc. Exemplarily, when the pin type of the electronic device to be tested is a metal pin, the preset distance can be set to 5 mm; when the pin type of the electronic device to be tested is a non-metallic pin, the preset distance can be set to 2 mm. Among them, the specific value of the preset distance can be set according to the actual situation, and no specific limitation is made here.

The third figure is a control principle structure block diagram of an electronic device lead length measuring device provided in the second embodiment of the present invention, and the fourth figure is a measurement structure schematic diagram of an electronic device lead length measuring device provided in the second embodiment of the present invention. Based on the above embodiment 1, optionally, referring to the third and fourth figures, at least two second support frames are horizontally fixedly arranged on the motor output screw 201, and the two second support frames are arranged at a preset angle in the same horizontal plane; a measurement sensing module is correspondingly arranged at the second preset position of each second support frame.

It should be noted that this embodiment can realize automatic measurement and judgment of the pin lengths of two electronic devices to be tested (including the same pin type and different pin types) at the same time. For example, taking the measurement of the pin length of a non-metallic pin type electronic device to be tested (the corresponding measurement sensing module is a capacitive proximity switch sensor) and a metallic pin type electronic device to be tested (the corresponding measurement sensing module is an inductive proximity switch sensor) as an example, in the technical solution of this embodiment, the implementation process of the electronic device pin length measuring device is as follows: in combination with the third figure and the fourth figure, when it is necessary to measure the pin length of the non-metallic pin type electronic device to be tested 11 and the metallic pin type electronic device to be tested 12, the user clicks the measurement start button on the human-machine interface. After clicking, the control module 500 receives the measurement start instruction. The control module 500 controls the motor 200 to rotate according to the measurement start command to drive the capacitive proximity switch sensor 101 and the inductive proximity switch sensor 102 to move upward from the initial position, that is, to move toward the pin ends of the non-metallic electronic device to be tested 11 and the metallic electronic device to be tested 12, respectively. When the capacitive proximity switch sensor 101 and the inductive proximity switch sensor 102 move to a preset distance from the pin ends of the non-metallic electronic device to be tested 11 and the metallic electronic device to be tested 12, respectively, they will sense the pins of their corresponding electronic devices to be tested and simultaneously feed back position sensing signals to the control module 500. After receiving the position sensing signal, the control module 500 controls the motor 200 to stop rotating, so that the capacitive proximity switch sensor 101 and the inductive proximity switch sensor 102 stop moving, and obtains the stop position of the capacitive proximity switch sensor 101 and the inductive proximity switch sensor 102. Then, the control module 500 can calculate the lengths of the pins of the two electronic devices to be tested according to the initial position, the stop position, the preset distance, and the fixed position of the initial end of each pin of the electronic device to be tested (this is a known quantity, and the specific value can be determined according to the actual installation setting). And after calculating the lengths of the pins of the two electronic devices to be tested, it is judged whether the lengths of the pins of the two electronic devices to be tested meet the preset conditions. If it is satisfied, the length of the pin of the electronic device to be tested is sent to the display module 600 for display, so as to facilitate the reference of relevant personnel. Otherwise, an alarm signal is generated and sent to the alarm module 700, and the alarm module 700 sends out an alarm message to prompt relevant personnel to handle it. It can be seen that the electronic device pin length measuring device can realize the automatic measurement of the lengths of the pins of two electronic devices to be tested at the same time, which can greatly improve the measurement efficiency, and compared with the existing manual auxiliary instrument measurement method, it can avoid the problem of poor measurement accuracy caused by the inability to accurately control the measurement at all times due to frequent manual caliper measurement. And it can greatly reduce the workload of manual work, reduce the load of manual work, ensure product quality and improve production efficiency.
