Description

Technical Field

[0001] The invention belongs to the technical field of electronic components, and in particular relates to a pin header connector production device. Background Art

[0002] Connectors usually consist of two parts: metal pins and plastic shells. According to the arrangement of the pins, pin header connectors can be divided into two types: straight-in type and right-angle type; according to the number of pins, it covers a variety of specifications from simple 2-pin to complex 40-pin and above; and according to the distance between the pins, the most common standard is a spacing of 0.1 inches (i.e. 2.54 mm). In order to ensure a close fit between the pins and the shell and sufficient mechanical strength, the manufacturing process of the pin header connector often adopts an injection molding process. Specifically, during the production process, the metal pins are first pre-placed inside the mold, and then the molten plastic material is injected. After it cools and solidifies, the metal pins are firmly wrapped in the plastic shell to form a complete pin header connector. Although this design can ensure the functionality, durability and reliability of the connector, it has the following problems in the actual application and production process:

[0003] First of all, in the production process of pin header connectors, the loading of metal pins is a key link; when dealing with the problem of loading metal pins of pin header connectors, the main challenge is due to the different shapes of the two ends of the metal pins. Specifically, one end is usually a flat head design, the purpose is to ensure good contact and welding quality with the printed circuit board (PCB); while the other end may be a pointed design, the purpose is to facilitate the insertion of the pin into another connector or socket. Therefore, in the process of automated loading, the two ends of the pin must be accurately distinguished, otherwise it is easy to cause installation errors, which will affect the performance and reliability of the final product. In addition, considering the diversity of pin header connectors, the number of metal pins required for a single connector can vary from a simple 2-pin to a complex 40-pin and above; this multi-specification production demand makes the batch loading of metal pins more complicated, making the metal pin loading of pin header connectors that need to be mass-produced more severe. In addition, in addition to the difference between flat heads and pointed heads, pins also have straight-in and right-angle design differences. These additional design differences further increase the complexity and precision requirements in the loading and assembly process.

[0004] Secondly, after solving the problem of feeding the metal pins, the next problem is the injection molding of the plastic shell. The injection molding process of the pin header connector shell usually includes multiple steps such as preheating, injection molding, cooling and demolding. These steps themselves constitute a relatively cumbersome process, which restricts the production efficiency of the pin header connector. Considering that the number of metal pins required for a single pin header connector can vary from a simple 2-pin to a complex 40-pin and above, coupled with the problem of feeding the metal pins themselves, these factors work together to further reduce the production efficiency of the pin header connector.

[0005] In summary, in the production process of the pin header connector in the prior art, there are at least problems of difficulty in feeding the metal pins and low efficiency in injection molding of the plastic shell. Summary of the invention

[0030] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left end", "above", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it will not be described in detail in this embodiment.

[0032] The pin header connector includes a metal pin and a plastic shell, the two ends of the pin are a head end and a tail end respectively, and the pin is divided into a straight-insert pin and a right-angle pin; the above is common knowledge of the pin header connector.

[0033] Embodiment 1

[0034] A pin header connector production device, the production device comprises a molding module 1 for producing the shell and an assembly module 2 for assembling the pins; this embodiment is mainly described with respect to the assembly module 2, specifically as follows:

[0035] See also Figure 1 , Figure 4The assembly module 2 includes a fixture 3, on which a groove 31 is provided, and the groove 31 is used to place the pin; the fixture 3 is provided with a groove 31 matching the metal pin to fix the pin to prevent it from shifting during transportation. The fixture 3 is equidistantly arranged on the transport mechanism 21 and is rotatably connected to the transport mechanism 21; the fixture 3 can switch between the detection state and the loading state on the transport mechanism 21; when the fixture 3 is in the detection state, the length direction of the pin on the fixture 3 is perpendicular to the transport direction of the transport mechanism 21; when the fixture 3 is in the loading state, the length direction of the pin on the fixture 3 is parallel to the transport direction of the transport mechanism 21; visual inspection mechanisms 22 and execution components are provided on both sides of the transport mechanism 21; the fixture 3 is in the detection state to facilitate the loading of the pin and the visual inspection mechanism 22 to detect and distinguish the two ends of the pin; the visual inspection technology is used to automatically identify the different features of the two ends of the pin, and the direction of the pin is automatically adjusted by the execution component, avoiding the tediousness and potential errors of manual correction. After detecting and distinguishing the two ends of the pin, the actuator rotates the fixture 3 from the detection state to the loading state, and at the same time makes the pin heads on the fixture 3 face the same direction. Through the two-way conversion mechanism of the fixture 3 (detection state and loading state), the direction of the pins is unified and quickly positioned, which improves the accuracy and efficiency of automated assembly.

[0036] Specifically, the unloaded fixture 3 is moved from the molding module 1 area to the loading area by the transportation mechanism 21. At this time, the fixture 3 is in the detection state, that is, the groove 31 on the fixture 3 is perpendicular to the transportation direction, which is convenient for manual or mechanical arm to place the pins. The fixture 3 with the pins placed continues to move along the transportation mechanism 21 and enters the visual inspection area. The visual inspection mechanism 22 identifies the two ends of the pin through a camera or other optical sensor to distinguish between the head end and the flat end. After the inspection is confirmed, the execution component rotates the fixture 3 from the inspection state (perpendicular to the transportation direction) to the loading state (parallel to the transportation direction) according to the visual inspection results, and ensures that the head ends of all pins are in the same direction. The fixture 3 that has completed the rotation continues to move along the track to the vicinity of the molding module 1. At this time, the pins are ready to be assembled with the molding mold of the plastic shell. The shell is injection molded by the molding module 1 to complete the assembly of the pin connector.

[0037] See also Figure 4 , Figure 5, a reset spring is provided between the clamp 3 and the transport mechanism 21, under the action of the reset spring, the clamp 3 is in the detection state; the transport mechanism 21 is provided with a limit track 23, and the limit track 23 is divided into a vertical section 231 and a parallel section 232; the actuator is arranged at the junction of the vertical section 231 and the parallel section 232; the clamp 3 is in the detection state in the vertical section 231, and the clamp 3 is in the feeding state in the parallel section 232; a control block 32 is provided on the clamp 3, and when the clamp 3 is in the parallel section 232, the control block 32 cooperates with the limit track 23 to put the clamp 3 in the feeding state. Through the cooperation of the reset spring and the limit track 23, the clamp 3 automatically returns to the detection state without external force, and when it is in a specific position (parallel section 232), the control block 32 and the limit track 23 cooperate to maintain the feeding state. This method simplifies the equipment structure, reduces the demand for actuators, and reduces energy consumption and maintenance costs.

[0038] Specifically, after the detection and confirmation by the execution component, the clamp 3 reaches the junction of the vertical section 231 and the parallel section 232 of the limit track 23. The execution component overcomes the force of the reset spring according to the visual detection result, rotates the clamp 3 to the loading state (that is, the groove 31 on the clamp 3 is parallel to the transportation direction), and ensures that the head ends of all pins are in the same direction. As the clamp 3 enters the parallel section 232 of the limit track 23, the control block 32 cooperates with the limit track 23 to prevent the clamp 3 from returning to the detection state due to the action of the reset spring, thereby ensuring that the pin heads are in the same direction and the arrangement direction of the pins is parallel to the transportation direction.

[0039] See also Figure 4 , Figure 5 , Figure 6, the execution component includes a push block 24 and a control component 25; the push block 24 has a guide surface 241, when one end of the clamp 3 contacts the guide surface 241, the clamp 3 can be deflected and rotated from the detection state to the feeding state; the control component 25 is used to control whether the push block 24 contacts the clamp 3; the execution components located on both sides of the transportation mechanism 21 are respectively a first execution component 26 and a second execution component 27, when the visual inspection mechanism 22 detects that the head end of the pin is located on the side of the first execution component 26, the first execution component 26 contacts the clamp 3; when the visual inspection mechanism 22 detects that the head end of the pin is located on the side of the second execution component 27, the second execution component 27 contacts the clamp 3; when the clamp 3 rotates from the detection state to the feeding state, the head end of the pin is oriented in the same direction. By setting two execution components (a first execution component 26 and a second execution component 27), a suitable execution component is selected to contact the clamp 3 according to the result of visual inspection, so as to ensure that the head end of the pin is always oriented in the same direction, thereby avoiding the error of traditional manual adjustment.

[0040] Specifically, the pin is rotated to the correct direction: when the visual inspection mechanism 22 detects that the head end of the pin is located on the side of the first execution component 26, the control component 25 activates the first execution component 26, so that the push block 24 contacts the clamp 3. One end of the clamp 3 contacts the guide surface 241 on the push block 24, pushing the clamp 3 to deflect and rotate from the detection state to the feeding state. When the visual inspection mechanism 22 detects that the head end of the pin is located on the side of the second execution component 27, the control component 25 activates the second execution component 27, so that the push block 24 contacts the clamp 3. Similarly, one end of the clamp 3 contacts the guide surface 241 on the push block 24, pushing the clamp 3 to deflect and rotate from the detection state to the feeding state.

[0041] See also Figure 1 , Figure 4 , Figure 5 , the transport mechanism 21 is a feeding belt or a reciprocating feeding mechanism, the visual inspection mechanism 22 is a CMOS visual inspection mechanism 22 or a CCD visual inspection mechanism 22, and the control component 25 is a slide, a telescopic component or a swing arm mechanism. The fixture 3 is in a detection state, and the length direction of the pins on the fixture 3 is perpendicular to the transport direction of the transport mechanism 21, so that the visual inspection mechanism 22 can detect and distinguish the two ends of the pins; through the detection and distinction results of the visual inspection mechanism 22, the execution component makes the head ends of the pins on the fixture 3 face the same direction, and rotates the fixture 3 from the detection state to the feeding state and enters the parallel section 232 of the limit track 23; when in the feeding state, when moving from the parallel section 232 of the limit track 23 to the vertical section 231, under the action of the reset spring, the fixture 3 is switched to the detection state.

[0042] Specifically, after completing a round of loading, the clamp 3 is in the loading state in turn. At this time, when the clamp 3 in the loading state moves from the parallel section 232 of the limiting track 23 to the vertical section 231, under the action of the reset spring, the clamp 3 automatically switches back to the detection state and prepares for the next cycle.

[0043] See also Figure 6 , Figure 7 , the pins are divided into straight-in pins and right-angle pins; the fixture 3 also includes: a base 33, the base 33 is fixedly arranged on the transport mechanism 21; a vertical rod 34, the vertical rod 34 is rotatably arranged on the base 33, the reset spring acts between the vertical rod 34 and the base 33, and an adjustment block 35 is slidably arranged on the vertical rod 34; a support plate 36, the groove 31 is opened on the support plate 36; the support plate 36 is divided into a first support plate and a second support plate, the first support plate and the second support plate are both rotatably arranged on the vertical rod 34 On the rod 34, both bottom ends are provided with connecting ears 37; a transmission rod 38, the two ends of the transmission rod 38 are rotatably connected to the connecting ears 37 and the adjusting block 35; the first support plate and the second support plate can be adjusted to a parallel state and a vertical state through the adjusting block 35, the connecting ears 37 and the transmission rod 38; when the first support plate and the second support plate are in a parallel state, direct-insert pins can be placed; when the first support plate and the second support plate are in a vertical state, right-angle pins can be placed. Through the design of the adjusting block 35, the connecting ears 37 and the transmission rod 38, the clamp 3 can adapt to different types of pins (direct-insert and right-angle), which improves the versatility and flexibility of the device.

[0044] Specifically, the fixture 3 can be adjusted according to the type of pins to be loaded: if a straight-in pin needs to be placed, the position of the adjustment block 35 is adjusted so that the first support plate and the second support plate are in a parallel state, and the length direction of the pin is parallel to the transportation direction, which is suitable for the placement of straight-in pins. If a right-angle pin needs to be placed, the position of the adjustment block 35 is adjusted so that the first support plate and the second support plate are in a vertical state, and the length direction of the pin is perpendicular to the transportation direction, which is suitable for the placement of right-angle pins.

[0045] The comparison between the assembly module 2 in this embodiment and the conventional pin processing technology is as follows:

[0046] In the traditional pin processing process, the vibration screening tray technology is usually used. It mainly uses vibration to achieve large-scale automatic arrangement of pins. When the pins are placed on the vibration screening tray, the tray vibrates at a set frequency so that the pins can be arranged in a certain direction. However, at this stage, the two ends of the pins are not distinguished, that is, the pins have not been arranged in a directional manner. In order to further ensure that all pins have a uniform direction, a technical solution combining a visual recognition system and a blowing device is usually used. First, the visual recognition system scans the pins on the vibration screening tray and determines the direction of each pin through image analysis technology. Once pins with different orientations are detected, the system triggers the corresponding blowing device. At this time, the blowing device accurately aligns those pins whose orientation does not meet the standard and blows them off from the arranged queue through precisely controlled airflow, thereby unifying the direction of all pins. Although the vibration screening tray can achieve preliminary arrangement, since the initial orientation of the pins is random, additional steps are required to ensure the consistency of the orientation of the pins, which affects the overall production efficiency. Furthermore, since the orientation of the pins is random when they enter the vibration screening plate, this means that even after a second vibration arrangement, the orientation of the pins may not be consistent, which will seriously affect the overall production efficiency of the pin connector.

[0047] In contrast, by directly identifying both ends of the pin through the visual detection mechanism 22 and combining with the execution component for instant adjustment, the uniform direction arrangement of all pins can be quickly achieved, which reduces unnecessary repeated operations and significantly improves production efficiency. In traditional technology, for different types of pins (such as straight-in and right-angle types), it is necessary to replace different screening trays or adjust equipment parameters, which increases the complexity of operation. In the embodiment, through the design of the fixture 3, different types of pins can be easily adapted without frequent replacement of equipment or adjustment of parameters, which improves the flexibility and adaptability of the production line.
