The swing block and the detection rod are in a disconnected state, and the detection signal line and the signal OV line are disconnected from communication. The controller determines that the component is inserted well, significantly improving the judgment of the goodness of the plug-in, thereby improving the quality of the plug-in and solving the problem in the prior art that the plug-in quality is poor due to forming a circuit through the plug-in head connecting the component pin and the base pin-cutting head to judge the goodness of the plug-in.

The detection base 31 is pin-connected to the output shaft of the driving cylinder 22, and the driving cylinder 22 drives the detection base 31 and the movable knife 51 to move together. The detection base 31 is provided with an installation groove 311. The detection rod 33 penetrates through the detection base 31 and is movably connected. The detection signal wire 35 is connected to the detection rod 33. The swing block 32 is rotatably connected to the end of the detection base 31 away from the driving mechanism 20, and the signal OV wire 36 is arranged on the detection base 31. The swing block 32 swings between a conducting position and a discontinuous position, and the conducting position is closer to the detection rod 33 than the discontinuous position.

[0043] Among them, please refer to Figure 9 , Figure 10 , the detection rod 33 includes a first connection section 331, a detection section 332 and a second connection section 333. The detection section 332 is located in the installation groove 311. One end of the detection section 332 is connected to one end of the first connection section 331, and the other end of the first connection section 331 penetrates through the detection base 31.

A card slot 335 is provided at the other end of the second connection section 333, and the detection signal wire 35 is clamped in the card slot 335, with a compact structure and cost savings. An adjustment groove 334 is provided at the other end of the second connection section 333, and the adjustment groove 334 is used to rotate the detection rod 33, which is convenient for adjustment and improves the operation efficiency.

[0044] The first connecting section 331, the second connecting section 333, and the detection section 332 are all set to be rod-shaped, and the diameter of the detection section 332 is smaller than the diameters of the first connecting section 331 and the second connecting section 333.

[0045] Please refer to Figure 9 、 Figure 11 , the swing block 32 includes a swing bar 321, a convex portion 322, and a contact portion 323. One end of the swing bar 321 is disposed close to the detection rod 33. The upper end of the swing bar 321 is connected to the convex portion 322, and the convex portion 322 is rotatably connected to the detection seat 31. The lower end of the other end of the swing bar 321 is connected to the contact portion 323, and the end of the other end of the swing bar 321 contacts the end of the movable knife 51. The end of the contact portion 323 close to the movable knife 51 protrudes from the end of the swing bar 321 and is in contact connection with the inner side wall of the groove 521, improving the efficiency of swinging.

[0046] A guiding inclined surface 324 is provided at the end of the other end of the swing bar 321 in the moving direction of the movable knife 51. The distance from the upper end of the guiding inclined surface 324 to the movable knife 51 is greater than the distance from the lower end of the guiding inclined surface 324 to the movable knife 51. The guiding inclined surface 324 contacts the end of the movable knife 51 and is used to transfer the reaction force when the movable knife 51 trims the leads to the swing block 32, causing the swing block 32 to rotate clockwise and improving the stability of the force transfer.

[0047] One end of the spring 34 passes through the detection seat 31 and is fixedly connected to the contact portion 323, and the other end of the spring 34 is fixedly connected to the driving mechanism 20, which is beneficial to protecting the device. At the same time, when the component 70 has no leads 71, it can prevent the movable knife 51 from driving the swing block to rotate.

[0048] In this embodiment, please refer to Figure 4 、 Figure 12 , the fixed knife mechanism 40 includes a fixed knife 41, a cover plate 42, and a recovery pipe 43. One end of the fixed knife 41 is fixedly connected to the conical end of the support seat 21, and a clearance groove 411 for placing the leads 71 of the component 70 is provided at the other end of the fixed knife 41. A recovery pipe 43 is provided below the clearance groove 411. The recovery pipe 43 is vertically arranged and is used to guide the trimmed leads 71 to the recovery position, which is beneficial to environmental protection and saves labor costs. The cover plate 42 is screwed to the fixed knife 41. A guiding groove 421 is provided below the cover plate 42, and the end of the movable knife 51 away from the detection seat 31 passes through the guiding groove 421, improving the stability of the movement of the movable knife 51.

[0049] In this embodiment, please refer to Figure 8 , Figure 12 , Figure 13 . The movable knife mechanism 50 includes a movable knife 51, a fixed block 52 and a rotating rod 53. One end of the movable knife 51 is drivingly connected to the other end of the swing block 32. The movable knife 51 moves between a position to be cut and a cutting position. The cutting position is closer to the avoidance groove 411 than the position to be cut, and the cutting position is used for trimming the legs of the component 70.

[0050] The structure of the fixed block 52 is similar to that of the swing block 32. The fixed block 52 is provided with a supporting portion, and the supporting portion is pin-connected to the end of the movable knife 51. The end of the movable knife 52 is thickened, which can improve the bearing strength of the movable knife 52 and extend its service life. The fixed block 52 is located in the mounting groove 311. The fixed block 52 is provided with a groove 521, and the swing block 32 is located in the groove 521, making reasonable use of space. One end of the rotating rod 53 sequentially passes through the detection seat 31, the fixed block 52 and the swing block 32. Both the fixed block 52 and the swing block 32 are rotatably connected to the detection seat 31 through the rotating rod 53. One end of the fixed block 52 away from the detection rod 33 is pin-connected to the end of the movable knife 51, and the diameter of the hole of the movable knife 51 for sleeving the pin is larger than the diameter of the pin, that is, there is a gap between the end of the movable knife 51 and the pin, which is convenient for transmitting the reaction force of the movable knife 51 to the swing block 32. One end of the swing block 32 away from the detection rod 33 protrudes from the groove 521 and contacts the end of the movable knife 51, which is convenient for the movable knife 51 to drive the swing block 32 to rotate, with a compact structure and cost savings.

[0051] The controller is electrically connected to the detection signal line 35 and is used to receive the signal of the detection signal line 35 and judge whether the component 70 is inserted properly.

[0052] Initially, the swing block 32 is located at the discontinuous position, the movable knife 51 is located at the position to be cut, the detection signal line 35 is disconnected from the signal OV line 36, and the controller does not receive the signal of the detection signal line 35. When the swing block 32 is located at the conduction position, one end of the swing block 32 close to the driving mechanism 20 is in contact connection with the detection rod 33, the detection signal line 35 is conducted with the signal OV line 36, the movable knife 51 is located at the cutting position, and the controller receives the signal of the detection signal line 35. When the swing block 32 is located at the discontinuous position, the movable knife 51 is located at the cutting position, there is a gap between the swing block 32 and the detection rod 33, the detection signal line 35 is disconnected from the signal OV line 36, and the controller does not receive the signal of the detection signal line 35 and alarms to indicate that the component 70 is inserted poorly.

[0053] The horizontal plug-in shear pin missing component detection device 10 drives the swing block 32 to swing through the reaction force of the movable knife 51 shearing the pin 71, and then contacts and connects with the detection rod 33, so that the detection signal line 35 and the signal OV line 36 are connected, thereby judging that the component 70 is well inserted. When the movable knife 51 moves to the cutting position, the component 70 is not inserted well, and the movable knife 51 has no reverse force to prompt the swing block 32 to swing. The swing block 32 and the detection rod 33 are in a disconnected state, and the detection signal line 35 and the signal OV line 36 are disconnected. The controller judges that the component 70 is not inserted well, which significantly improves the judgment of the good situation of the plug-in, thereby improving the quality of the plug-in.

[0054] The principle of the present invention is described in detail below.

[0055] During installation, first pass the detection rod 33 through the detection seat 31, then combine the fixed block 52 and the swing block 32 and install them into the detection seat 31, and fix them with the rotating rod 53 passing through the center hole. Press the limit pin of the movable knife 51 into the fixed block 52, then screw the spring 34 into the detection seat 31 with a top screw, and just support the combination of the fixed block 52 and the swing block 32, and lock the spring 34 with a top screw. Connect the assembled assembly to the output shaft of the driving cylinder 22 through the connecting pin of the driving cylinder 22 and fix it with screws. Install the movable knife 51 on the pin of the movable knife 51, and combine it with the fixed knife 41 to form a cutting knife structure. Connect the signal 0V line 36 and the detection signal line 35, adjust the gap between the swing block 32 and the detection rod 33, and the assembly of the present invention is completed.

[0056] During the insertion, the present invention forms a pin shearing detection for a pair of pins 71 of the component 70. When the pins are sheared, the output shaft of the driving cylinder 22 extends to drive the detection mechanism 30 and the movable knife 51 to move forward. When the movable knife 51 contacts the pins 71 of the component 70, the pins 71 of the component 70 hit the fixed knife 41. Since there is a gap between the movable knife 51 and the pins of the movable knife 51, they are momentarily blocked and paused. The fixed block 52 and the swing block 32 continue to move forward in combination. The swing block 32 hits the movable knife 51 and then swings. The other end of the swing block 32 contacts the detection rod 33, and at the same time pushes the movable knife 51 forward to complete the pin shearing. The detection signal line 35 is connected to the signal 0V line 36 to complete the pin shearing detection.

[0057] When the pin 71 is not cut, the swing block 32 does not swing due to the elastic force of the spring 34, and the other end of the swing block 32 does not contact the detection rod 33. The controller does not detect the output of the conduction signal, indicating that the component 70 is not inserted properly, and the controller warns that the component 70 is not inserted properly. The structure is exquisitely designed, and the detection function is realized by using the reaction force, which is suitable for high-speed operation occasions and is not affected by the product PCB copper coating process.

[0058] Due to the adoption of the above horizontal plug-in and pin-cutting missing component detection device, compared with the prior art, the beneficial effects of the present invention are as follows: The present invention relates to a horizontal plug-in and pin-cutting missing component detection device, which includes a driving mechanism, a detection mechanism, a fixed knife mechanism, a movable knife mechanism and a controller. The detection mechanism includes a detection seat, a swing block, a detection rod, a detection signal line and a signal OV line. The detection seat is connected to the driving mechanism, and the driving mechanism drives the detection seat to move. The detection rod penetrates through the detection seat and is movably connected, and the detection signal line is connected to the detection rod. The swing block is rotatably connected to one end of the detection seat away from the driving mechanism, and the signal OV line is arranged on the detection seat. The swing block swings between a conduction position and an interruption position, and the conduction position is closer to the detection rod than the interruption position. The fixed knife mechanism includes a fixed knife, one end of the fixed knife is fixedly connected to the driving mechanism, and the other end of the fixed knife is used to fix the component. The movable knife mechanism includes a movable knife, one end of the movable knife is connected to the other end of the swing block, and the movable knife moves between a position to be cut and a cutting position, and the cutting position is closer to the component than the position to be cut, and the cutting position is used for cutting the pins of the component. The controller is electrically connected to the detection signal line and is used to receive the signal of the detection signal line and judge whether the component is missing pins. Initially, the swing block is located at the interruption position, the movable knife is located at the position to be cut, the detection signal line and the signal OV line are disconnected, and the controller does not receive the signal of the detection signal line. When the swing block is located at the conduction position, the end of the swing block close to the driving mechanism is in contact connection with the detection rod, the detection signal line and the signal OV line are conducted, the movable knife is located at the cutting position, and the controller receives the signal of the detection signal line. When the swing block is located at the interruption position, the movable knife is located at the cutting position, there is a gap between the swing block and the detection rod, the detection signal line and the signal OV line are disconnected, and the controller does not receive the signal of the detection signal line and alarms to indicate that the component is missing pins. The horizontal plug-in and pin-cutting missing component detection device drives the swing block to swing and then contact and connect with the detection rod through the reaction force of the movable knife cutting the pins, so that the detection signal line and the signal OV line are conducted, thereby judging that the component is inserted well. When the movable knife moves to the cutting position, the component is inserted poorly, and there is no reverse force to prompt the swing block to swing, the swing block and the detection rod are in a disconnected state, the detection signal line and the signal OV line are disconnected from communication, and the controller judges that the component is inserted poorly, significantly improving the judgment of the good condition of the plug-in, thereby improving the quality of the plug-in, and solving the problem that in the prior art, the quality of the plug-in is poor due to judging the good condition of the plug-in by forming a path through the plug-in head to connect the component pins and the base pin-cutting head.

[0059] In summary, although the present invention has been disclosed above with the preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those of ordinary skill in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
