[0012] like Figure 1 As shown, the circuit board in the current automobile sensor generally includes a chip 11, a ceramic sheet 12 and a side card 13. Glue is manually dispensed on the ceramic sheet 12, and then the chip 11 is correspondingly glued to the ceramic sheet 12. Finally, the side card 13 is correspondingly clamped between the chip 11 and the ceramic sheet 12 to form a circuit board, and the shell is subsequently installed manually.

[0013] like Figure 2 As shown, the present invention provides an edge card loading and cutting device, including a discharge roll 101, an adjustment component 102 and a cutting component 103 which are arranged in sequence, and a clamping component 104 located above the edge card discharge station. The edge card is discharged from the discharge roll 101 and fed into the adjustment component 102, and the adjustment component 102 drives the edge card to continue to move forward to the cutting component 103, and the cutting component 103 cuts the lower edge card 13 and feeds it onto the workpiece to clamp the chip 11 and the ceramic sheet 12.

[0014] Please focus on Figure 3 The adjustment component 102 includes a base plate 1022, a rotating wheel 1025 is movably mounted on the base plate 1022 through a motor three 1021, and a left track 1023 and a right track 1024 are respectively arranged on both sides of the rotating wheel 1025, and a back plate 1028 is mounted on the base plate 1022, a limit block 1027 is mounted on the back plate 1028, and a cover plate 1026 is installed on the left track 1023 and the right track 1024, the limit block 1027 and the cover plate 1026 are used to limit the movement of the side card 13; wherein a plurality of guide nails 1029 are evenly arranged on the rotating wheel 1025 around the axis of the rotating wheel 1025, and the guide nails 1029 are used to guide the movement of the side card 13 and correct the position of the side card 13 at the same time.

[0015] The side card 13 is fed into the right track 1024 by the discharge roll 101. When the side card 13 reaches the rotating wheel 1025, the guide nail 1029 hooks the hole on the side card 13. At the same time, the rotating wheel 1025 rotates, and the guide nail 1029 drives the side card 13 to move forward. At the same time, the subsequent holes of the side card 13 are hooked on the subsequent guide nails 1029, thereby guiding and correcting the position of the side card 13 to avoid the side card 13 from being skewed. Then, the rotating wheel 1025 feeds the side card 13 into the left track 1023.

[0016] Please focus on Figure 4 The cutting assembly 103 includes a bracket 3 1035, a base 2 1031 mounted on the bracket 3 1035, a top cover 1036 movably mounted on the base 2 1031 through a guide shaft 1032 and a cylinder 3 1034, a limiting step 1033 is provided on the guide shaft 1032, and the limiting step 1033 is used to limit the moving range of the top cover 1036, and support columns 1037 are symmetrically installed in the top cover 1036, and both ends of the moving block 1038 are placed on the steps 1039 of the support column 1037 through rollers 10310, and a cutting knife 10314 is installed on the moving block 1038, and a linear guide rail 10313 is installed in the base 2 1031. A receiving seat 10312 is installed on the linear guide rail 10313, and a rear track 10311 is installed on the base 1031. The end face of the receiving seat 10312 is lower than the end face of the rear track 10311. The rear track 10311 is used to receive the side card 13 sent from the left track 1023, and a positioning block 10315 is provided just above the end of the rear track 10311 close to the cutting knife 10314. The positioning block 10315 is installed on the moving block 1038. The bottom surface of the cutting knife 10314 is lower than the bottom surface of the positioning block 10315. At the same time, a cylinder five is installed at the rear of the base 1031, and the cylinder five is used to push the moving block 1038.

[0017] The side card 13 in the left track 1023 enters the rear track 10311. When the side card 13 moves to the receiving seat 10312, the cylinder three 1034 is turned on. Under the action of gravity, the positioning block 10315 presses the side card 13 on one side to limit the movement of the side card 13 on one side. At the same time, the cutting knife 10314 cuts the side card 13 on the other side. This device avoids the side card 13 being damaged by the direct force of the cylinder three 1034. By adjusting the weight of the moving block 1038, the side card 13 can be cut while avoiding damage.

[0018] At this time, the moving block 1038 falls on the linear guide rail 10313, and the cutting knife 10314 cooperates with the receiving seat 10312 to clamp the cut side card 13, and then the cylinder five is turned on. The cylinder five pushes the moving block 1038, and the moving block 1038 moves along the step 1039 through the roller 10310, driving the side card 13 to move forward. This device converts the moving friction into rolling friction, which not only reduces wear, but also makes the movement of the moving block 1038 very light and flexible.

[0019] Please focus on Figure 5 The clamping assembly 104 includes a bracket 1041, a connecting plate 1043 is movably mounted on the bracket 1041 through a cylinder 1042, a pressing pin 1044, a pressing block 1045 and a limiting block 1046 are installed on the connecting plate 1043, and a limiting groove 1047 is provided on the limiting block 1046.

[0020] When cylinder four 1042 is turned on, pressure pin two 1044 presses against tooling 14, and pressure block two 1045 presses against the workpiece. After cylinder five is turned on, cylinder five sends the edge card 13 clamped by the cutting knife 10314 and the receiving seat 10312 onto the workpiece along the limiting groove 1047 to ensure that the edge card 13 clamps the chip 11 and the ceramic sheet 12.

[0021] Motor three 1021, cylinder three 1034, cylinder five and cylinder four 1042 are communicatively coupled to the control panel.

[0022] The control panel contains a PLC controller, which can program the numerical control system. The PLC is used as the central control system, and the touch screen is used to realize the program input and operation control of the whole machine, so as to realize the full automation of the transportation process. The control system can be used as a system that connects various actuators to move according to the logical trajectory, and the actuators can be controlled by programming to run according to the required operation steps.

[0023] Based on the above device, the present invention also proposes an operating method using the above-mentioned edge card feeding and cutting device, comprising the following steps: Step 1: the side card is discharged from the discharge roll 101 and fed into the adjustment component 102. The adjustment component 102 drives the side card 13 to move forward and guides and corrects the position of the side card 13; Step 2: The adjustment component 102 drives the edge clamp to continue to move forward to the cutting component 103, and the pressing component 104 presses against the workpiece; Step 3: the cutting assembly 103 cuts the lower edge card 13, clamps the edge card 13 and sends it to the workpiece; Step 4: The edge card 13 clamps the chip 11 and the ceramic sheet 12.

[0024] This device realizes automatic cutting and loading of the edge card; at the same time, this device avoids the damage of the edge card 13 by directly applying force by the cylinder three 1034. By adjusting the weight of the moving block 1038, it can both cut the edge card 13 and avoid damaging the edge card, and convert the moving friction into rolling friction, which not only reduces wear, but also makes the movement of the moving block 1038 very light and flexible.
