Description

Technical Field

[0001] The present application relates to the technical field of connector processing, and in particular to a connector pin insertion machine with short circuit detection. Background Art

[0002] Connectors, also known as connectors or connectors, are common components in electronic engineering and are used to establish circuit connections in electronic devices. The female end of the connector is equipped with one or more rows of copper pins for conducting electricity, and each pin is electrically connected to the corresponding conductive part on the male end of the connector.

[0003] The existing female end of the connector is usually processed by a pin insertion machine (for example: a connector automatic pin insertion machine disclosed in the Chinese invention patent with the public number CN103701007A), which can insert the pins one by one into the corresponding sockets on the plastic shell, and can realize automatic loading of the plastic shell and the pins, insert all the pins on the plastic shell, and bend the inserted pins according to the use requirements, thereby realizing the automated production of the female end of the connector.

[0004] In order to ensure the firmness of the pins inserted into the plastic shell, the pins are usually fitted with the sockets by interference fit. This causes a large scratch between the pin surface and the edge of the socket when the pins are inserted into the sockets. Some pins with less than smooth surfaces will produce copper wires extending outward after being scratched. The copper wires will pass through the sockets to one side of the plastic shell along with the pins. If the copper wires are attached to adjacent pins, the two pins will be short-circuited, affecting the use of the connector.

[0005] Therefore, in order to ensure the quality of connector female end products, a connector pin insertion machine with short circuit detection is urgently needed. Summary of the invention

[0014] By adopting the above technical scheme, the female end of the connector is obtained after the plastic shell pin is inserted and bent. During the process of the female end of the connector being transported and fed by the feeding device, the blowing component can blow air to it, effectively blow off and blow off the copper wire, so as to reduce the probability of short-circuiting the pins of the female end of the connector; the detection device then performs circuit detection on the pins of the female end of the connector to detect the quality of the female end of the connector; then the exclusion device screens the female end of the connector that still has a short-circuit phenomenon according to the detection result of the detection device and recycles it in a recycling box, and re-inspects the quality after subsequent processing; thereby, the probability of short-circuiting the pins of the female end of the connector after processing can be effectively reduced, and the quality of the female end of the connector can be effectively guaranteed.

The feeding track 41 is used to guide the plastic shell 11 or the female connector end 1 to move along a straight line for feeding; the feeding assembly 42 is used to control the plastic shell 11 or the female connector end 1 to move a certain distance at a certain interval in a certain number of groups.

[0059] Reference Figure 3 and Figure 4The track of the feed track 41 is a horizontal straight line. The two ends of the feed track 41 are a feed end 413 and a discharge end 414, respectively. The first channel 411 is provided inside the feed track 41 to match the plastic shell 11, and the extension track of the first channel 411 is the same as the track of the feed track 41. Both sides of the feed track 41 in the horizontal direction are provided with a clearance groove 412 for the end of the plug pin 12 to be exposed. The clearance groove 412 runs through one side of the feed track 41 and communicates with the first channel 411; the plastic shell 11 or the female end 1 of the connector is fed and moved in the first channel 411 in a position state that is horizontal to the width direction of the plastic shell 11 and perpendicular to the extension track of the first channel 411, and the end of the plug pin 12 to be bent and the end of the plug pin 12 after bending can both extend out of the corresponding clearance groove 412.

[0060] Reference Figure 2 and Figure 3 The feeding assembly 42 includes a frame 421 , a movable frame 422 , a movable rod 423 , a plurality of shifting blocks 424 , a plurality of fourth driving members 425 and a plurality of fifth driving members 426 .

[0061] The frame 421 is fixedly installed on the feeding track 41, the movable frame 422 is located above the feeding track 41 and is movably connected to the frame 421 along the vertical direction; the fourth driving member 425 is fixedly installed on the frame 421, and can drive the movable frame 422 to move relative to the frame 421; the movable rod 423 is movably connected to the movable frame 422 along a direction parallel to the trajectory of the feeding track 41, and the fifth driving member 426 is fixedly installed on the movable frame 422, and can drive the movable rod 423 to move relative to the movable frame 422; multiple shift blocks 424 are all fixedly installed on the movable rod 423, and are spaced apart along the moving direction of the movable rod 423.

[0062] In the process that the fourth driving member 425 drives the movable frame 422 to move and the fifth driving member 426 drives the movable rod 423 to move, the multiple shifting blocks 424 all move on the side of the clearance groove 412 on the feeding track 41 where the pin 12 passes through. When the fourth driving member 425 drives the movable frame 422 to move upward to the limit position, the height position of the shifting block 424 will be higher than the clearance groove 412; when the fourth driving member 425 drives the movable frame 422 to move downward to the limit position, the height position of the shifting block 424 is aligned with the clearance groove 412 in the horizontal direction. When the fourth driving member 425 drives the movable frame 422 to move downward to the limit position, in the process that the fifth driving member 426 drives the movable rod 423 to move from one limit position to another limit position, the multiple shifting blocks 424 can drive multiple groups of plastic shells 11 or connector female ends 1 to move a certain distance toward the discharge end 414, and the moving distance is equal to the distance that the fifth driving member 426 drives the movable rod 423 to move.

[0063] The fourth drive member 425 and the fifth drive member 426 are connected by signals to form a match. When the feeding assembly 42 is in the initial state, the movable frame 422 is in a position state where it moves upward to the limit position, and the movable rod 423 is in a position state where it moves toward the direction close to the feeding end 413 to the limit position. At this time, the fourth drive member 425 first drives the movable frame 422 to move downward to the limit position, and then the fifth drive member 426 drives the movable rod 423 to move toward the direction close to the discharging end 414 to the limit position, and then the fourth drive member 425 drives the movable frame 422 to move upward to the limit position, and finally the fifth drive member 426 drives the movable rod 423 to move toward the direction close to the feeding end 413 to the limit position, so that the feeding assembly 42 returns to the initial state. In this cycle, the feeding assembly 42 can realize continuous control of the plastic shell 11 or the female end 1 of the connector to move a certain distance at a certain interval in a group of a certain number.

In this embodiment, since the pin insertion device 2 and the bending device 3 are both existing technologies in the field, they are not described here in detail, and they are only briefly shown in the drawings.

[0066] Reference Figure 5 and Figure 6 The cleaning device 5 is located on the side of the feeding track 41 away from the bending device 3, and includes a blowing assembly 51 and a third driving member 52. The blowing assembly 51 includes a seat body 511, an air pump 512, a plurality of air pipes 514 and a plurality of air nozzles 513.

[0067] The seat body 511 is aligned with the feeding track 41 in the horizontal direction, the seat body 511 can move relative to the feeding track 41 in a direction parallel to the track of the feeding track 41, and the third driving member 52 can drive the seat body 511 to move relative to the feeding track 41. In this embodiment, the third driving member 52 is preferably a servo cylinder; since the servo cylinder is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0068] The air pump 512 is fixedly mounted on the seat body 511, and a plurality of air nozzles 513 are fixedly mounted on one side of the seat body 511 close to the feeding track 41, and the blowing direction of the air nozzles 513 is toward the adjacent clearance groove 412. A plurality of air pipes 514 correspond to a plurality of air nozzles 513 one by one, and the two ends of the air pipes 514 are respectively connected and communicated with the air pump 512 and the corresponding air nozzles 513. When the air pump 512 is in operation, the gas can be delivered to the corresponding air nozzles 513 through the plurality of air pipes 514, and then blown out by the air nozzles 513, and the blown gas can blow off the copper wire in the groove 111, separate it from the pin 12, and blow it out of the groove 111. In this embodiment, the blowing assembly 51 preferably includes three air nozzles 513 and three air pipes 514; and the blowing direction of the air nozzles 513 is preferably horizontal and perpendicular to the track of the feeding track 41; since the air pump 512 is a common prior art, it will not be described in detail here, and it is only briefly indicated in the attached drawings.

[0069] When the third driving member 52 is in operation, it can drive the seat body 511 to reciprocate, so that the blowing assembly 51 can remove the copper wires on the same group of multiple connector female ends 1 through the three air nozzles 513 .

[0070] Furthermore, preferably, the three air nozzles 513 are evenly spaced on the seat body 511 along the moving direction of the seat body 511, and the spacing between adjacent air nozzles 513 is greater than the length of the plastic shell 11. When the three air nozzles 513 move back and forth with the movable seat to remove the copper wires from a group of multiple female connector ends 1, each female connector end 1 is only cleaned by air blowing from one air nozzle 513 at the same time, so as to improve the cleaning effect of the female connector end 1.

The two detection members 61, two movable blocks 62 and two first driving members 63 are symmetrically distributed on both sides of the feeding track 41, and the detection member 61 is aligned with the feeding track 41 in the horizontal direction.

[0072] The movable block 62 can move relative to the feeding track 41 in a direction horizontal and perpendicular to the track of the feeding track 41, and the first driving member 63 can drive the corresponding movable block 62 to move. In this embodiment, the first driving member 63 is preferably a servo cylinder; since the servo cylinder is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0073] The detection member 61 has a plurality of probes 611 at one end close to the feeding track 41. When the movable block 62 moves to the extreme position in the direction close to the feeding track 41, the plurality of probes 611 can respectively contact and abut against the ends of the plurality of pins 12 on the same side of the same group of plurality of connector female ends 1.

[0074] The other end of the detection member 61 extends outward with a conductive line, and the ends of the two detection members 61 away from the corresponding probes 611 are connected to a device with a current detection function, and the ends of the two detection members 61 away from the corresponding probes 611 also form a circuit connection. In this embodiment, since the above-mentioned configuration in the detection device 6 is a common prior art, it is not described here, and the lines and the device with a current detection function are omitted in the drawings.

[0075] The multiple probes 611 on the detection parts 61 located on both sides of the feeding track 41 are staggered along the track of the feeding track 41. When the two detection parts 61 are moved to the extreme position in the direction close to the feeding track 41, the multiple probes 611 on the two detection parts 61 respectively contact and abut against different pins 12 on the same group of multiple connector female ends 1.

[0076] When the multiple probes of the two detection components 61 are in contact with and abut against the ends of different pins 12 on the same group of multiple connector female ends 1, at this time, if the copper wire formed on a pin 12 in the groove 111 overlaps with the adjacent pin 12 to form a circuit connection, a connected circuit will be formed between the two detection components 61 through the above-mentioned two pins 12 and the overlapping copper wire. At this time, it means that the corresponding connector female end 1 has a short circuit phenomenon, that is, the connector female end 1 is a defective product.

[0077] Reference Figure 2 and Figure 5 The removal device 7 is located at one end of the feeding track 41 close to the discharge end 414, and the removal device 7 includes a movable track 71, a second driving member 72, and a recovery box 73.

[0078] The movable track 71 can move relative to the feed track 41 in a horizontal direction and perpendicular to the track of the feed track 41, and the second driving member 72 can drive the movable track 71 to move. In this embodiment, the second driving member 72 is preferably a servo cylinder; since the servo cylinder is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0079] During the movement of the movable track 71 , its length direction is kept parallel to the track of the feeding track 41 , and the movable track 71 has a second channel 711 inside that is matched with the first channel 411 .

[0080] When the movable track 71 moves to the extreme position in the direction close to the feeding track 41, one end of the movable track 71 in the length direction is connected to the discharge end 414 of the feeding track 41, the first channel 411 is the same as the second channel 711, and the connector female end 1 can maintain the same position state and enter the second channel 711.

[0081] A downwardly inclined discharge hopper 8 is fixedly installed on one side of the movable track 71 away from the feeding track 41 for discharging the connector female ends 1 passing through the second channel 711, and a container for collecting the connector female ends 1 that have passed the inspection is placed at the lower end of the discharge hopper 8.

[0082] When the movable track 71 moves to the extreme position in the direction away from the feeding track 41 , the movable track 71 is separated from the feeding track 41 , and the female connector end 1 leaving the first channel 411 will fall directly downward.

[0083] The recovery box 73 is fixedly installed between the discharge hopper 8 and the feeding track 41, and the height position is lower than the movable track 71. The recovery box 73 has a recovery space 731 inside for recovering the connector female end 1 that fails the inspection (i.e., defective products). The connector female end 1 that leaves the first channel 411 can directly fall into the recovery space 731 for recovery. After the recovered connector female end 1 is processed for copper wire overlap, a qualified connector female end 1 can be obtained and put into use again.

[0084] Furthermore, in order to facilitate the elimination device 7 to eliminate the corresponding defective products according to the detection results of the detection device 6, the elimination device 7 preferably also includes a movable part 74, a material removal part 75, a sixth driving part 76 and a seventh driving part 77. The above structures are all installed on the same side of the feeding track 41 and are located on the same side of the feeding track 41 as the bending device 3.

[0085] The movable member 74 can move relative to the feed track 41 in a direction parallel to the track of the feed track 41, and the sixth driving member 76 can drive the movable member 74 to move. The material-pickup member 75 is movably connected to the movable member 74, and the material-pickup member 75 is aligned with the feed track 41 in the horizontal direction. The moving direction of the material-pickup member 75 is horizontal and perpendicular to the moving direction of the movable member 74; the seventh driving member 77 is fixedly mounted on the movable member 74, and can drive the material-pickup member 75 to move relative to the movable member 74. In this embodiment, it is preferred that the sixth driving member 76 and the seventh driving member 77 are both servo cylinders; since the servo cylinder is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0086] When the connector female end 1 moves to the limit position along the feed track 41 toward the discharge end 414 under the action of the feed assembly 42, the same group of multiple connector female ends 1 can be controlled to move by the material-displacing member 75. When the material-displacing member 75 is in the state of being close to the limit position of the feed track 41, the movable member 74 can move to drive the material-displacing member 75 to contact the end of the pin 12 on the connector female end 1, thereby driving the same group of multiple connector female ends 1 to move.

[0087] The detection device 6 is connected to the exclusion device 7 by signal. When the detection device 6 does not detect a short circuit in the connector female end 1, the movable track 71 will maintain an extreme position state close to the feeding track 41; at this time, the sixth drive member 76 and the seventh drive member 77 will cooperate to drive the same group of multiple connector female ends 1 to enter the second channel 711 through the first channel 411, and discharge them into the discharge hopper 8 through the second channel 711.

[0088] When the detection device 6 detects that the connector female end 1 has a short circuit, the sixth driving member 76 and the seventh driving member 77 cooperate to drive the connector female end 1 that has passed the detection in the same group of multiple connector female ends 1 to pass through the first channel 411 and enter the second channel 711, and then stop driving the remaining multiple connector female ends 1 in the same group to move; then the second driving member 72 drives the movable track 71 to move and separate from the feeding track 41, and then the sixth driving member 76 and the seventh driving member 77 cooperate to drive the connector female end 1 that has failed the detection (i.e., defective products) to leave the feeding track 41 through the first channel 411 and fall into the recovery box 73, and then continue to stop driving the remaining multiple connector female ends 1 in the same group to move; then the second driving member 72 drives the movable track 71 to move and reset, and then the sixth driving member 76 and the seventh driving member 77 cooperate to drive the connector female end 1 that has passed the detection to move; this cycle is repeated until all defective products in the same group of multiple connector female ends 1 are excluded and recovered in the recovery box 73.

[0089] The implementation principle of a connector pin insertion machine with short circuit detection in the embodiment of the present application is as follows:

[0090] Under the action of the feeding device 4, the pin device 2 and the bending device 3 work together to complete the insertion of multiple pins 12 and the bending of the pins 12 after the insertion on the plastic shell 11 before the feeding track 41 is close to the feed end 413, so as to obtain the connector female end 1 that has been preliminarily processed; then the cleaning device 5 blows air to the connector female end 1 through the blowing component 51, so that the copper wire formed during the insertion of the pins 12 is blown off and blown off; then the detection device 6 performs circuit detection on the connector female end 1 to detect whether there is a short circuit in the connector female end 1; then the exclusion device 7 screens the connector female end 1 according to the detection result of the detection device 6, and the connector female ends 1 that pass the detection are collected after being discharged, while the connectors that fail the detection will be recycled in the recycling box 73 and will be discharged and used again after further processing.

[0091] Embodiment 2:

[0092] Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 lies in the cleaning device 5.

[0093] Reference Figure 7 and Figure 8 The cleaning device 5 also includes a plurality of connecting components 53 , a guide rail 54 , an intercepting net 55 and a chip collecting box 56 .

[0094] A plurality of connection components 53 correspond to a plurality of air nozzles 513 one by one, and the air nozzles 513 are connected to the seat body 511 through the corresponding connection components 53. The connection components 53 include a connection head 531 and a connection rod 532, wherein the connection rod 532 is located on a side of the seat body 511 close to the feeding track 41, and one end of the connection rod 532 in the length direction is fixedly connected to the seat body 511, and the length direction thereof is horizontal and perpendicular to the moving direction of the seat body 511; a connection portion is extended outwardly from one end of the connection head 531, and the connection portion is rotatably connected to the end of the corresponding connection rod 532 away from the seat body 511, and the rotation axis is parallel to the moving direction of the seat body 511; the air nozzle 513 is fixedly installed at one end of the connection head 531 away from the connection portion, and the blowing direction of the air nozzle 513 is also toward the direction away from the connection portion.

[0095] The guide track 54 is fixedly installed on one side of the seat body 511 close to the feeding track 41. The overall extension direction of the guide track 54 is parallel to the movement direction of the movable seat, and the guide track 54 is a serpentine track. The connector 531 has a spherical structure, and the spherical structure of the connector 531 rotates with the guide track 54. During the movement of the movable seat, it can drive a number of connectors 531 to move along the serpentine track of the guide track 54. During this process, the height position of the air nozzle 513 will continue to change, and the blowing direction of the air nozzle 513 will also continue to change. The gas blown by the air nozzle 513 will continue to blow toward the groove 111, so as to improve the blowing and clearing effect of the blowing component 51 on the copper wire on the female end 1 of the connector.

[0096] Furthermore, in order to reduce the probability of the copper wire falling around after being blown away from the connector female end 1, the copper wire is intercepted by an interception net 55 and collected by a chip collection box 56.

[0097] The interception net 55 is fixedly mounted on one side of the guide track 54 close to the feeding track 41, and the interception net 55 is located between the gas nozzle 513 and the feeding track 41. The mesh holes on the interception net 55 can allow gas to pass through and can intercept the copper wire at the same time.

[0098] The chip collecting box 56 is fixedly installed between the feeding track 41 and the intercepting net 55, and is located below the feeding track 41. After the copper wire intercepted by the intercepting net 55 falls under the action of gravity, it can fall into the chip collecting box 56 for collection.

[0099] The implementation principle of a connector pin insertion machine with short circuit detection in the embodiment of the present application is as follows:

[0100] During the process of the cleaning device 5 performing air blowing to clean the copper wires on the female end 1 of the connector, the third driving member 52 drives the seat body 511 to reciprocate and drives the plurality of air nozzles 513 to perform reciprocating sweeping and blowing on the plurality of female ends 1 of the connector, and during the process of the connector 531 moving along the guide track 54, the position of the air nozzles 513 for blowing and cleaning the female end 1 of the connector continuously changes, so as to improve the effect of the cleaning device 5 for blowing and cleaning the copper wires on the female end 1 of the connector;

[0101] After the copper wire is blown away and leaves the female end 1 of the connector, it will be intercepted by the interception net 55 and fall into the chip collection box 56 under its own gravity for collection, which is convenient for subsequent staff to handle the copper wire and can reduce the pollution caused by the copper wire falling everywhere.

[0102] Embodiment 3:

[0103] Reference Figure 6 and Fig. 9 The difference between this embodiment and the first embodiment is that the detection device 6 and the detection member 61 have a plurality of conductive wires 612 at the ends of the plurality of probes 611 for contacting the ends of the pins 12 .

[0104] The conductive wire 612 is soft and has a certain elastic deformation ability. When the conductive wire 612 is not in contact with the end of the pin 12, the length direction of the plurality of conductive wires 612 is parallel to the length direction of the probe 611, and the plurality of conductive wires 612 together form a cylindrical whole. In this embodiment, the conductive wire 612 is preferably a copper wire.

[0105] When the end of the probe 611 contacts the end of the pin 12 through multiple conductive wires 612, the conductive wire 612 in direct contact with the pin 12 will bend and deform while avoiding the end of the pin 12. The bent and deformed conductive wire 612 maintains contact with the end of the pin 12 under the tendency of its own elastic deformation recovery, so as to ensure the reliability of the detection device 6 in short-circuit detection of the connector female end 1.

[0106] At the same time, replacing the end of the probe 611 with a plurality of conductive wires 612 to directly contact and abut the end of the pin 12 can effectively reduce the degree of damage to the end of the pin 12 of the connector female end 1 during the short circuit detection process, thereby effectively ensuring the quality of the final connector female end 1 product.

[0107] The implementation principle of a connector pin insertion machine with short circuit detection in the embodiment of the present application is as follows:

[0108] During the process of the detection device 6 performing short-circuit detection on the connector female end 1, after the first driving member 63 drives the detection member 61 to move towards the direction close to the feeding track 41, the multiple conductive wires 612 located at the end of the probe 611 will replace the end of the probe 611 to contact and abut against the end of the pin 12, so as to reduce the wear on the pin 12 during the short-circuit detection process, thereby ensuring the quality of the final connector female end 1 product.

[0109] Embodiment 4:

[0110] Reference Figure 5 and Fig.10 The difference between this embodiment and embodiment 1 lies in the exclusion device 7. The recovery box 73 is also fixedly provided with a plurality of baffles 78 in the recovery space 731 for reducing the damage caused by the direct fall and collision of the connector female end 1 that fails the inspection, and a cover plate 79 is provided at the bottom of the recovery box 73 for controlling the discharge of defective products in the recovery space 731.

[0111] The baffle 78 is an elastic rectangular plate-shaped structure as a whole, and is fixedly installed in the recovery box 73, and is installed in a position state inclined in the length direction. The bottom of the baffle 78 is its own inclined lower end, and both ends of the baffle 78 in the width direction are fixedly connected to the inner wall of the recovery space 731. In this embodiment, the baffle 78 is preferably made of rubber material.

[0112] The inclined upper end of the baffle 78 is fixedly connected to the inner wall of the recovery space 731, and a through hole 781 for defective products to pass through is formed between the inclined lower end of the baffle 78 and the inner wall of the adjacent recovery space 731. The space above the baffle 78 in the recovery space 731 and the space below it will communicate through the corresponding through hole 781. At this time, the multiple baffles 78 form a recovery channel 732 in the recovery space 731 for defective products to move downward in an orderly manner.

[0113] The bottom of the recovery box 73 is provided with a discharge port 733 for discharging defective products. The discharge port 733 is connected to the bottom of the recovery channel 732, and can discharge multiple defective products at the same time. The cover plate 79 is movably installed at the bottom of the recovery box 73, and can control the opening and closing of the discharge port 733. After the cover plate 79 closes the discharge port 733, it can maintain the current position state. In this embodiment, the cover plate 79 is preferably rotatably connected to the recovery box 73, and the cover plate 79 and the recovery box 73 are preferably connected by a corresponding lock to realize the above function; since the cover plate 79 with the above function and the lock with the above function are both common existing technologies, they are not described here in detail. The cover plate 79 is only briefly indicated in the accompanying drawings, and the lock is omitted.

[0114] The implementation principle of a connector pin insertion machine with short circuit detection in the embodiment of the present application is as follows:

[0115] After the rejection device 7 causes the defective products to fall into the recovery space 731, the defective products will first contact the baffle 78, and then move downward along the recovery channel 732 to gradually accumulate in the recovery space 731, which can effectively reduce the collision damage caused by the direct fall of the defective products, so as to ensure the quality of the defective products and facilitate the subsequent separate processing of the defective products to obtain qualified connector female end 1 products;

[0116] After a certain amount of defective products in the recovery space 731 is recovered, the staff can open the cover 79 to discharge the defective products in the recovery space 731 and take out the defective products in the recovery space 731.

[0117] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
