[0027] The solder-free crimping system includes an acquisition module, an analysis module, a control module and an alarm module.

The acquisition module is used to acquire images and pressure data after crimping, and feed them back to the analysis module. The analysis module includes a judgment unit and a counting unit. The judgment unit is used to judge abnormal crimping of connectors according to the pressure data collected by the acquisition module. The counting unit is used to count the pins 4 and connectors with abnormal pressure. The control module is electrically connected to the pressing mechanism 2 and the feeding mechanism 3. The control module is used to control the feeding of connectors and the crimping operation of connectors. The alarm module is used to analyze and judge the alarm prompts when abnormalities occur.

[0028] Solder-free crimping process of LRM module combined connector solder-free crimping device: Step 1: The control module controls the feeding mechanism 3 to feed the connector and the pressing mechanism 2 to clamp the connector and press the connector onto the circuit board.

[0029] Step 2: The acquisition module acquires the image and pressure data of the connector after crimping, and the analysis module determines the abnormality of the connector insertion.

[0030] Specifically, during crimping, the acquisition module collects pressure data detected by the pressure sensor 1 212 and the pressure sensor 2 223. The acquisition module records the actual pressure value detected by the pressure sensor 1 212 as Fi, where i is the number of pins 4 on the connector, and the actual pressure detected by the pressure sensor 2 223 as f'; The judgment unit of the analysis module is provided with a pressure interval (Fn, F+n) corresponding to the pressure detected by the pressure sensor 1 212 and a pressure interval (f-n', f+n') corresponding to the pressure detected by the pressure sensor 2 223. F is the standard pressure when the pressure sensor 1 212 detects, f is the standard pressure when the pressure sensor 2 223 detects, and n and n' are both allowable deviation coefficients of the actual pressure value when the pin 4 is crimped, which are set by the staff according to actual needs; A counting threshold A is set in the counting unit according to the number of pins 4 on the connector, and a counting threshold B is set according to the total number of connectors on the circuit board; In single crimping, only Fi∈(Fn, F+n) means the pressure of pin 4 is normal; In other cases, the pressure of pin 4 is abnormal.

[0031] When Fi≥F+n, the pressure value of pin 4 is large, and the counting unit counts the pin 4 with the large pressure value, and the count value is a; When Fi≤Fn, the pressure value of the pin 4 is small, and the counting unit counts the pins 4 with small pressure values, and the count value is a'.

[0032] When a+a'<A, the corresponding connector is crimped normally; When a+a'≥A, the corresponding connector crimping is abnormal, and the counting unit counts the abnormal connector continuously; Case 1: a≥1 / 2A and a'≥1 / 2A, the main reason for the abnormal crimping of the connector is the problem of the connector itself, and the count value is b1; Case 2: a≥1 / 2A>a' or a'≥1 / 2A>a, f'∈(f-n',f+n'), then the main reason for the abnormal crimping of the connector is the problem of the connector itself, and the count value is still b1; Case 3: a≥1 / 2A>a' but f'≥f+n', the main reason for the abnormal crimping of the connector is that the pressure of cylinder 3 26 is too large, causing the pin 4 to be pressed too hard, and the count value is b2; Case 4: a≥1 / 2A>a' but f'≤f-n', then the main reason for the abnormal crimping of the connector is that the position of pin 4 is offset during crimping, and the count value is b3; Case 5: a'≥1 / 2A>a but f'≥f+n', the main reason for the abnormal crimping of the connector is that the position of pin 4 is offset during crimping, and the count value is still b3; Case 6: a'≥1 / 2A>a but f'≤f-n', the main reason for the abnormal crimping of the connector is that the pressure of cylinder 3 26 is small, the force on pin 4 is small and it is not fully pressed in, and the count value is b4; At the same time, the acquisition module continues to collect images after each connector crimping is completed. When the judgment unit identifies that there is deformation at the plug-in position on the circuit board, it continues to judge that it is caused by the position offset of pin 4. The circuit board is deformed after plugging. The counting unit counts again and the count value is still b3. At the same time, when the control module controls cylinder 24 to drive the transverse seat 25 to carry the air claw 28 to clamp the connector, the judgment unit identifies the shape, size and spacing of the conductive holes on the circuit board, and compares them with the standard conductive holes set inside to ensure that there is no abnormality in the circuit board, which is beneficial to ensure the crimping quality of the connector.

[0033] When b1, b2, b3 and b4 do not reach B, it is a normal situation; When one of the count values ​​of b1, b2, b3, and b4 reaches B, it is fed back to the alarm module and the control module, and the alarm module issues an alarm prompt. When b1≥B, the control module controls the subsequent crimping work to stop, and the staff checks whether there is any abnormality in the batch of connectors; when b2≥B, the control module controls the cylinder three 26 to reduce the downward pressure; when b3≥B, the control module controls the subsequent crimping work to stop, and the staff checks whether there is any offset in the crimping position; when b4≥B, the control module controls the cylinder three 26 to increase the downward pressure.

[0034] Through the above steps, the situation after each crimping of the connector can be monitored, the connector with abnormal crimping can be discovered in time, and the accuracy and efficiency of solderless crimping can be improved.

10. The solder-free crimping process of the solder-free crimping device for the LRM module combined connector according to claim 9, characterized in that: The specific content of step 2 is: during crimping, the acquisition module acquires the pressure data detected by pressure sensor 1 (212) and pressure sensor 2 (223), the acquisition module records the actual pressure value detected by pressure sensor 1 (212) as Fi, i is the number of pins (4) on the connector, and the acquisition module records the actual pressure detected by pressure sensor 2 (223) as f'; The judgment unit of the analysis module is provided with a pressure interval (Fn, F+n) corresponding to the pressure detected by the pressure sensor 1 (212) and a pressure interval (f-n', f+n') corresponding to the pressure detected by the pressure sensor 2 (223), F is the standard pressure when the pressure sensor 1 (212) detects, f is the standard pressure when the pressure sensor 2 (223) detects, and n and n' are both allowable deviation coefficients of the actual pressure value when the pin (4) is crimped; A counting threshold value A is set in the counting unit according to the number of pins (4) on the connector, and a counting threshold value B is set according to the total number of connectors on the circuit board; In a single crimping, only Fi∈(Fn, F+n), the pressure of pin (4), is normal; In other cases, the pressure of the pin (4) is abnormal.
