Description

Technical Field

[0002] Pin headers are generally widely used in the connection of PCB boards and are known as universal connectors. They are generally paired with female headers, wire terminals and other connectors. With the competition in the pin header connector market, some manufacturers now reduce costs by improving electroplating (imitation gold) and materials (green steel, alloy, etc.), but this also reduces the product's usability and lifespan. During the pin header processing process, the pin header production equipment inserts the plastic parts into the pin header, then punches them into a K shape, bends them, and finally inspects them to get a complete product.

[0003] Ordinary processing of needle arrangement is done by direct manual operation or segmented operation of equipment.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a pin header production device, which has the following beneficial effects:

[0018] 1. Before the needle insertion operation, a probe and a detection mechanism are set up to determine whether the needle body is missing a needle, so as to control the power supply of the needle insertion operation for manual troubleshooting and needle replenishment, which improves the feasibility of the fully automatic assembly line and greatly reduces the workload of manual troubleshooting.

[0019] 2. The needle row production equipment is provided with a connecting rod structure. During the operation of the pressing plate, the pressing plate rotates around the rotating shaft. Due to the existence of the movable opening, the second connecting shaft can move inside the movable opening to ensure that the rotation of the pressing plate is not affected. At the same time, the connecting rod rotates around the first connecting shaft. During this process, the connecting rods on both sides of the middle play a limiting role, further preventing the pressing plate from shifting on both sides during the rotation process, thereby strengthening the entire bending mechanism, making the structure less prone to dislocation and damage, and extending the service life.

[0020] 3. The needle row production equipment is provided with a movable pressure roller and a limit frame. When the movable pressure roller presses down from above the copper needle, the movable pressure roller can rotate on the inner side of the limit frame. When the movable pressure roller contacts the surface of the copper needle, the rotation of the movable pressure roller can reduce the friction between the copper needle and the surface of the copper needle, thereby effectively reducing the wear on the surface of the copper needle due to friction, which is beneficial to improving the quality of the product.

[0021] 4. The needle row production equipment has three groups of feeding ports opened on the movable plate of the counting and packaging mechanism. In the process of collecting products, the bag opening is turned outward and covered on the edge of the feeding port, and then the edge of the bag opening is fixed by the rubber block of the pressure block structure to complete the placement of the bag. The bags of the three groups of feeding ports are installed in sequence to facilitate the collection of products. The installation and arrangement of the bags are more convenient, which is convenient for collecting products.

[0022] 5. The needle row production equipment is provided with a pressing block structure. After loosening the upper nut and the lower nut, the upper pressing plate and the lower pressing plate can be separated from the connecting frame. Then the threaded rod can be moved up or down to adjust the height of the rubber block so as to apply appropriate pressure to the edge of the bag opening. Then the upper pressing plate and the lower pressing plate are fitted with the connecting frame, and then the upper nut and the lower nut are tightened to stabilize the position of the upper pressing plate and the lower pressing plate, thereby fixing the position of the rubber block. The degree of pressure on the rubber block used to clamp the bag opening can be adjusted, which is beneficial to the fixation of the bag opening. BRIEF DESCRIPTION OF THE DRAWINGS

The sliding match between the seat body 16 and the receiving mechanism 15 is opened and closed by the detection mechanism. When the detection mechanism detects that the number of the probe 22 and the needle body 21 is the same, it means that there is no shortage of needles. At this time, the detection mechanism starts the sliding match between the seat body 16 and the receiving mechanism 15. During the needle insertion operation, the needle body 21 is transported to the first groove 151 through the cooperation of the second vibration disk (not shown in the figure) and the feeding mechanism 19. The seat body 16 and the feeding mechanism 19 are installed on the workbench 14. The workbench 14 is also provided with a first vibration disk 10, a feeding track 12, a dotting mechanism 3, a rear insertion mechanism 4, a K-marking mechanism 5, a bending mechanism 6, a needle detecting mechanism 7, a waste discharge mechanism 8 and a counting and packaging mechanism 9 for forming an automated assembly line. The seat body 16, the material receiving mechanism 15 and the pushing block 17 are combined into the needle insertion mechanism 1. The specific process of the needle insertion operation is shown below.

[0044] The material receiving mechanism 15 is provided with a first groove 151 for supporting the needle body 21 and a second groove 152 for the probe 22 to pass through. The first groove 151 and the second groove 152 are connected, and the end of the needle body 21 and the probe 22 are electrically connected in the second groove 152. The needle body 21 is limited in the first groove 151 by the cooperation of the push block 17 and the probe 22.

[0045] The probe 22 and the detection mechanism are fixedly assembled on the base body 16, and a first guide groove 161 is provided on one side of the base body 16. A first slider 153 adapted to the first guide groove 161 is provided at the bottom of the material receiving mechanism 15. The base body 16 and the material receiving mechanism 15 achieve sliding cooperation through the cooperation of the first guide groove 161 and the first slider 153. A first pushing mechanism 18 is provided on the workbench 14 to push the first slider 153, so that the material receiving mechanism 15 reciprocates up and down.

[0046] It includes a push block 17 for pushing the needle body 21. The material receiving mechanism 15 is provided with a second guide groove 154 for the push block 17 to reciprocate. The bottom of the push block 17 is provided with a second slider 171 adapted to the second guide groove 154. The needle body 21 is separated from the first groove 151 through the mutual cooperation of the push block 17, the second guide groove 154 and the second slider 171. A second pushing mechanism 174 is provided on one side of the push block 17, so that the push block 17 pushes the needle body 21 into the plastic part 23.

[0047] The push block 17 is provided with a protrusion 172 for blocking and pushing the needle body 21, and the material receiving mechanism 15 is provided with a third groove 155 adapted to the protrusion 172. The third groove 155 is connected to the second groove 152. The cooperation between the protrusion 172 and the third groove 155 makes the movement of the push block 17 smoother and more stable.

[0048] An elastic mechanism 173 forcing the protrusion 172 to move away from the needle body 21 is provided between the pushing block 17 and the material receiving mechanism 15 . The elastic mechanism 173 is preferably a spring.

[0049] The probe 22 is a PIN needle, and the present application preferably uses a PIN needle. The PIN needle is a metal material used in a connector to complete the transmission of electrical signals, and is a relatively mature technology on the market.

[0050] The detection mechanism is a logic controller that cooperates with the probe 22 to receive signals. The detection mechanism and the probe 22 are connected through a signal line (not shown in the figure). Whether the probe 22 detects anything is fed back to the PLC through this signal line. The PLC is a control unit of the equipment. If the needle body is not recognized, the PLC will notify other steps or even suspend the insertion process. An alarm sound can be set on the PLC, and a sound will be emitted when a needle is missing to remind manual intervention.

[0051] Insertion operation process:

[0052] First, the needle body 21 is transported to the first groove 151 through the first vibrating plate 10 and the feeding mechanism 19, and the needle body 21 is supported by the first groove 151. The protrusion 172 on the push block 17 limits the needle body 21, and one end of the needle body 21 is placed in the second groove 152 and electrically connected to the probe 22. At this time, if the number of needle bodies 21 and the number of probes 22 are consistent, an alarm is used to remind manual intervention. If the number of manual inspections is inconsistent, the detection mechanism will cut off the power supply to prevent interpolation. If the number of needle bodies 21 and the number of probes 22 are consistent, or after manual arrangement, When the conditions for needle replenishment are met after checking, the first pushing mechanism 18 pushes the receiving mechanism 15 upwards, the needle body 21 leaves the probe 22, and the needle body 21 corresponds to the plastic part 23 on the feed track 12, and then the second pushing mechanism 174 pushes the pushing block 17 toward the plastic part 23, and the needle body 21 is inserted into the plastic part 23 to complete the needle insertion operation. The pushing block 17 is reset in the opposite direction with the cooperation of the elastic mechanism 173, and the first pushing mechanism 18 moves the receiving mechanism 15 downward, waiting to re-accept the next batch of needle bodies 21, and the plastic part 23 that has completed the needle insertion passes through the feed track 12 to the next process.
