Description

Technical Field

[0001] This utility model relates to the field of connector manufacturing technology, and in particular to an automated PIN pin pressing device. Background Technology

[0002] In the fields of electronics, communications, aerospace, and industrial equipment, connectors are core components for connecting circuits or mechanical parts, and their performance directly affects system reliability. PIN pins (or insertion pins, conductive terminals), as key components for transmitting current or signals in connectors, typically need to be installed within the connector's insulating body (such as a plastic housing) according to specific spacing, angles, and depths. In the existing technology, the installation methods of PIN pins mainly include manual pressing, semi-automatic mechanical assembly, and fully automatic assembly line operation. Among them, manual pressing is not only inefficient but also prone to low product quality and poor product consistency due to human error. Semi-automatic mechanical assembly improves the installation efficiency to some extent, but still requires manual operation. Existing automated pressing devices, such as the Chinese invention patent with application number "2020113533673" entitled "Device and Method for Automatic Feeding and Insertion of Double PIN Pins into PCB", use a double PIN pin blowing mechanism to transfer PIN pins. However, the gap between the PIN pin and the mounting hole is often very small. It uses an insertion method to drop the PIN pin into the mounting hole, and the accuracy of insertion is difficult to control, which poses a risk of insertion failure. When the PIN pin is pressed in the hole, it relies solely on the pressing of the upper and lower cylinders, which cannot guarantee that the PIN pin remains in a neutral position throughout the pressing process, thus leading to deviations in PIN pin pressing. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an automated PIN pin pressing device with a high degree of automation and good pressing accuracy.

[0004] This utility model discloses an automated PIN pin pressing device, which is used to press PIN pins onto a connector on a carrier. The carrier is mounted on a rotating station.

[0009] In one or more embodiments of this utility model, the transfer assembly is provided in multiple sets, arranged in a circular pattern and installed on the turntable.

[0010] In one or more embodiments of this utility model, the transfer assembly includes a vacuum suction rod, a first fixing member, and a first spring.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] It should be noted that, unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] As described in the background section, existing automated PIN press-fit devices have difficulty controlling the accuracy of PIN insertion, which poses a risk of insertion failure. When the PIN is pressed into the hole, the pressing is done solely by the cylinders at the top and bottom positions, which cannot guarantee that the PIN remains in a neutral position throughout the pressing process, thus leading to deviations in the PIN pressing accuracy.

[0031] For the above issues, please refer to the appendix. Figures 1-3 As shown, this utility model provides an automated PIN pin pressing device, which is used to press PIN pins onto connector bases on a carrier 300. In this embodiment, the carrier 300 is mounted on a rotary station 800, which is also equipped with other devices for processing connectors. This utility model mainly describes the pressing device in detail. The pressing device includes a base 100 and a pressing cylinder 20 mounted on the base 100, as well as a feeding assembly 40, a rotating assembly 50, a transferring assembly 60, and a lifting assembly 70. The feeding assembly 40 is used to receive PIN pins blown out from a vibratory feeder. In this embodiment, the pressing device can be used for pressing at least two types of PIN pins. The transfer component 60 is used to pick up the PIN pin on the feeding component 40 and, together with the rotating component 50, transfer the PIN pin to the carrier 300. At this time, the end of the pressing cylinder 20 moves downward along the third direction Z and pushes the upper part of the transfer component 60 downward. The end of the lifting component 70 moves upward and pushes the lower part of the carrier 300, thereby pressing the PIN pin onto the connector of the carrier 300. A second sensor 900 is provided on the rotating station 800. The second sensor 900 is used to detect the connector on the carrier 300.

[0032] In a further embodiment, see Appendix Figures 3-4As shown, the base 100 includes a support rod 10 and a first base plate 11 mounted on the support rod 10. A transfer assembly 40 is mounted on the first base plate 11. The transfer assembly 40 includes a second base plate 41, a feeding cylinder 42, a push rod 43, a fixing block 44, a first sensor 45, a feeding component 46, a feeding hole 461, a slider 47, a lifting cylinder 48, and a lifting rod 49. The second base plate 41 is fixedly mounted on the mounting plate 55. The feeding cylinder 42 is mounted on the second base plate 41. The movable end of the feeding cylinder 42 is connected to the push rod 43, and the other end of the push rod 43 is connected to the slider 47. A hollow fixing block 44 is also provided on the second base plate 41. The movement stroke of the slider 47 is inside the fixing block 44. The upper part of the fixing block 44 is provided with a feeding component 46. The other end of the feeding component 46 is connected to a vibratory feeder via a pipe to receive PIN needles. The middle of the feeding component 46... A feed hole 461 is provided, and a storage hole 471 is provided in the middle of the slider 47. When the PIN needle is conveyed to the feed hole 461 of the feeder 46 by the vibratory feeder, the storage hole 471 of the slider 47 is coaxially positioned with the feed hole 461, and the PIN needle enters the storage hole 471 of the slider 47. At least three sets of first sensors 45 are provided on both sides of the fixing block 44. The first sensors 45 are used to detect the type of PIN needle in the storage hole 471. The lifting cylinder 48 is installed at the bottom of the first base plate 11. The end of the lifting cylinder 48 is provided with a lifting rod 49. The first base plate 11 and the second base plate 41 have through holes at the projection position of the movable end of the lifting cylinder 48. When the slider 47 drives the PIN needle to move above the movable end of the lifting cylinder 48, the movable end of the lifting cylinder 48 pushes out the PIN needle in the storage hole 471 to facilitate the transfer component 60 to pick it up.

[0033] In a further embodiment, see Appendix Figures 3-4 As shown, the rotating assembly 50 includes a column 51 and a hollow rotating table 52 mounted on the column 51. The hollow rotating table 52 can be of model KTN130-10K. A turntable 53 is mounted on the hollow rotating table 52. The upper part of the turntable 53 is connected to the bottom of the first base plate 11 through a rotary joint 54 to enhance the stability during rotation. A mounting plate 55 is fixedly mounted on the side of the column 51, and a feeding mechanism 40 is mounted on the mounting plate 55. The turntable 53 is provided with multiple sets of transfer components 60. In this embodiment, there are two types of transfer components 60. Each transfer component 60 has two sets. Each type of transfer component 60 is arranged alternately and installed on the turntable 53 in a circumferential array. The number of transfer components 60 can be adjusted according to the production cycle.

[0034] For further implementation, please refer to the appendix. Figure 5As shown, the transfer assembly 60 includes a vacuum suction rod 61, a first fixing member 62, and a first spring 63. The first fixing member 62 is mounted on the turntable 53, and the vacuum suction rod 61 is slidably mounted in the first fixing member 62. A cavity is formed between the first fixing member 62 and the first spring 63, and the first spring 63 for resetting the vacuum suction rod 61 is installed in the cavity.

[0035] In a further embodiment, see Appendix Figures 6-8 As shown, the lifting assembly 70 includes a pad 71, a transverse cylinder 72, a sliding block 73, a first fixing member 74, a lifting block 75, an end cap 76, and a second spring 77. The transverse cylinder 72 is installed on the upper part of the pad 71, and the movable end of the transverse cylinder 72 is connected to the sliding block 73. The sliding block 73 and the lifting block 75 are in contact, and the contact surface between them is inclined. The first fixing member 74 is sleeved on the outer side of the lifting block 75 and is installed on the pad 71. The top of the first fixing member 74 is provided with an end cap 76, and the end cap 76 has an opening on the projection of the first fixing member 74. When the transverse cylinder 72 pushes the sliding block 73 close to the lifting block 75, the lifting block 75 passes through the opening at the top of the end cap 76 to press against the bottom of the carrier 300, thereby cooperating with the pressing cylinder 20 to complete the PIN pin pressing onto the connector of the carrier 300.

[0036] Workflow: When the PIN pin is blown into the storage hole 471 by the vibratory feeder, the feeding cylinder 42 pushes the slider 47 to the bottom of the transfer assembly 60, and the lifting cylinder 48 pushes the lifting rod 49 to move upward in the first direction to push the PIN pin out of the storage hole 471. Then, the transfer assembly 60 picks up the PIN pin through the vacuum suction rod 46. The hollow rotating platform 52 drives the turntable 53 to rotate, thereby moving the transfer assembly 60 with the picked-up PIN pin to the top of the carrier 300. At the same time, another set of transfer assemblies 60 rotates to the suction position. For the transfer assembly 60 above the carrier 300, the pressing cylinder 20 moves downward to squeeze the vacuum suction rod 61. The vacuum suction rod 61 releases the PIN pin at this time, thereby pressing the PIN pin onto the connector. To ensure the stability of the pressing, while the pressing cylinder 20 moves downward, the lateral cylinder 72 pushes the sliding block 73 close to the lifting block 75. The lifting block 75 protrudes from the opening at the top of the end cover 76 to press against the bottom of the carrier 300.

[0037] This utility model integrates a feeding component 40, a rotating component 50, and a transfer component 60. The feeding component 40 can automatically store and transport PIN pins, and the transfer component 60 can automatically pick up and transfer PIN pins. It does not require a lot of manual intervention, reduces manpower input, improves production efficiency, and effectively solves the problem of low efficiency in manual pressing and semi-automatic assembly.

[0038] Through a reasonable structural design, the transfer component 60 can accurately transfer the PIN pins, and the lifting component can stably hold the bottom of the carrier. Together with the pressing cylinder, it ensures that the PIN pins are in a neutral position during the pressing process, avoiding pressing deviations. This solves the problems of difficulty in controlling the accuracy of existing automated equipment and easy pressing deviations, thereby improving product quality and consistency.

[0039] The feeding assembly 40 is equipped with multiple sets of first sensors 45, which can detect the status of pin height, etc. The rotary station 800 is equipped with a second sensor 900, which can detect the connector on the carrier, so as to facilitate the timely detection of abnormalities, ensure the smooth progress of the pressing process, and improve production reliability.

[0040] The hollow rotating table and turntable structure of the rotating component 50 allow the transfer component 60 to be arranged and installed in a circular pattern, enabling multi-angle transfer operations. The design of the slider 47 and storage hole 471 in the feeding component 40, as well as the inclined contact sliding block and lifting block in the lifting component 70, not only ensure the functionality of each component, but also make the overall structure compact, stable in operation, and flexible in adjustment and configuration according to different production needs.

[0041] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
