Description

Technical Field

[0001] The utility model relates to the technical field of connector assembly, in particular to a transmission line for connector assembly. Background Art

[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 electroplating (imitation gold) and materials (green steel, alloy, etc.), but this also reduces the product's use characteristics and life. This connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its role is to act as a bridge between blocked or isolated circuits in the circuit, and to take on the task of current or signal transmission. It is usually used in conjunction with female headers to form a board-to-board connection; or used in conjunction with electronic wiring harness terminals to form a board-to-wire connection; it can also be used independently for board-to-board connection.

[0003] The conveying lines of the connector bodies of the existing double-row press-pin connector assembly equipment are mostly composed of two tracks (or multiple tracks). When the connector body needs to be transferred between different tracks, it is generally clamped and transferred by a robotic arm. However, the installation space required for the robotic arm is large and the movements are more complicated, so the processing efficiency is low.

[0004] In view of this, there is an urgent need for a transmission line for connector assembly. Summary of the invention

[0008] The material track changing mechanism includes a mounting seat, a track changing plate slidably arranged on the mounting seat, and a first driving component. The mounting seat is arranged between the loading end of the processing track and the discharging end of the loading track.

[0012] The track-changing plate is provided with a baffle, and when the unloading end of the track-changing groove is aligned with the loading end of the processing track, the baffle is sealed at the unloading end of the loading track.

[0013] The limiting plate is provided with a limiting bolt for limiting the sliding of the limiting plate.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0033] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0034] The following is combined with Figure 2-10 This application is described in further detail.

[0035] refer to Figure 2-3 The double-row pin connector assembly equipment shown in the figure is characterized in that it includes: a machine table 1, on which a feeding track 2, a material track changing mechanism 3, a processing track 4, a material moving mechanism 5, two pin row installation mechanisms 6 and a pin row re-pressing mechanism 7 are arranged. The material track changing mechanism 3 is used to move the connector body at the feeding track 2 to the processing track 4, and the material moving mechanism 5 is used to move the connector body on the processing track 4. The two pin row installation mechanisms 6 and the pin row re-pressing mechanism 7 are sequentially arranged on one side of the conveying stroke of the processing track 4. The two pin row installation mechanisms 6 respectively press one end of the two rows of pins into the connector body, and the pin row re-pressing mechanism 7 is used to re-press the two rows of pins on the connector body. In this way, the connector body (such as Figure 1 As shown, the finished connector, including a connector body and two rows of pins, is transported to the material track changing mechanism 3. After the track changing of the material track changing mechanism 3, the connector body enters the processing track 4 (at this time, the pin side of the connector body faces the pin installation mechanism 6 and the pin re-pressing mechanism 7). The moving mechanism 5 moves the connector body on the processing track 4, so that the connector body passes through the two pin installation mechanisms 6 respectively, and is inserted into the two rows of pins respectively. Finally, it passes through the pin re-pressing mechanism 7 for re-pressing, and the two rows of pins are inserted to the specified depth of the connector body. In this process, the degree of automation is high, and there is no need to manually place the connector body at different assembly links. The assembled connector is transported from the processing track 4 to the specified collection position, which improves the assembly efficiency of the connector and reduces labor costs.

[0036] refer to Figure 3-5 As shown, a feeding trough 21 is provided at the top of the feeding track 2, and the extension direction is consistent with the extension direction of the feeding track 2. A third card slot 22 is provided at the bottom of the feeding trough 21. In actual use, the connector body is continuously transported to the feeding trough 21 on the feeding track 2 by a vibration plate arranged at the feeding end of the feeding track 2 (when the connector body is placed in the feeding trough 21, one side of the connector body is in a vertical state, and the one side of the connector body faces the side of the pin installation mechanism 6, and the protruding ring plate on the side of the connector body is clamped in the third card slot 22, ensuring stable transportation of the connector body), and the connector body is continuously supplied to the subsequent assembly link.

[0037] refer to Figure 3-7As shown, a conveying groove 41 is provided on one side of the processing track 4, and the top and bottom surfaces of the conveying groove 41 are both provided with a second clamping groove 42. A positioning groove 43 is provided on the processing track 4. The conveying groove 41 passes through both ends of the processing track 4. The loading end of the processing track 4 is arranged at the discharging end of the loading track 2. By providing the conveying groove 41 on one side of the processing track 4, the connector body slides in the conveying groove 41, and the second clamping groove 42 is adapted to the ring plate protruding from the side of the connector body, so that the connector body is clamped on the processing track 4, ensuring that the pin side of the connector body faces one side of the pin installation mechanism 6 and the pin re-pressing mechanism 7, which is convenient for inserting the pin, and the conveying groove 41 passes through both ends of the processing track 4, so that the assembled connector finally slides out of the conveying groove 41 from the suspended end of the processing track 4 to complete the unloading process.

[0038] refer to Figure 3-6 As shown, when the connector body needs to be transferred on the feeding track 2 and the processing track 4, it is currently mostly transferred by a robot arm. The robot arm transfer has many movements and is relatively expensive. Therefore, a material track changing mechanism 3 is used to connect the connector body at the end of the feeding track 2 to the processing track 4. The installation space is small, the movements are few, and the transfer is stable and efficient. The specific structure of the material track changing mechanism 3 includes a mounting seat 31, a track changing plate 32 slidably arranged on the mounting seat 31 (a limiting groove is arranged at the top of the mounting seat 31, and the track changing plate 32 is clamped in the limiting groove) and a first driving component (the first driving component is a first cylinder, and the track changing plate 32 is installed at the output end of the first cylinder). The mounting seat 31 is arranged between the feeding end of the processing track 4 and the discharging end of the feeding track 2. A track changing groove 321 is arranged on one side of the track changing plate 32, and the top and bottom surfaces of the track changing groove 321 are both provided with a first clamping groove 32 2. The track changing groove 321 and the conveying groove 41 are on the same side of the processing track 4. The first driving component is used to drive the track changing plate 32 to slide on the mounting seat 31, so that the loading end of the track changing groove 321 is aligned with the unloading end of the loading track 2 or the unloading end of the track changing groove 321 is aligned with the loading end of the processing track 4. In this way, the first driving component drives the track changing plate 32 to slide on the mounting seat 31. When receiving materials, the loading end of the track changing groove 321 is aligned with the unloading end of the loading track 2. At this time, the connector body on the loading track 2 slides into the track changing groove 321, and then the unloading end of the track changing groove 321 is aligned with the loading end of the processing track 4. At this time, the connector body in the track changing groove 321 slides into the conveying groove 41 of the processing track 4, and so on and so forth, continuously transferring the connector body on the loading track 2 to the processing track 4, so that the connector body changes from being exposed on one side of the annular surface to being exposed on one side of the pin, which is convenient for subsequent pin assembly.

[0039] refer to Figure 4-6As shown, the mounting seat 31 is provided with a slide rail 33 in the direction opposite to the track changing slot 321, and a limit plate 34 is provided on the slide rail 33. The extension direction of the slide rail 33 is consistent with the extension direction of the track changing slot 321. When the feeding end of the track changing slot 321 is aligned with the unloading end of the feeding track 2, the end of the limit plate 34 is located in the track changing slot 321, and a limit bolt 36 is provided on the limit plate 34 for limiting the sliding of the limit plate 34. In order to prevent the connector body in the feeding track 2 from directly sliding off the end of the track changing slot 321 away from the feeding track 2 (and to limit the position of the connector body in the track changing slot 321 to ensure that the connector body is in the same position each time it slides into the track changing slot 321), by setting the limit plate 34, when the track changing slot 321 is aligned with the feeding slot 21, the end of the limit plate 34 is placed in the track changing slot In 321, the end position of the connector body is restricted to ensure the consistency of position and facilitate subsequent processing and assembly, and the limiting plate 34 is slidably clamped on the slide rail 33, so that the position of the limiting plate 34 can be adjusted to adapt to the positioning of connector bodies of different specifications, and the limiting bolt 36 passes through the limiting plate 34, so that the limiting bolt 36 can be rotated to fix the position of the limiting plate 34, and in order to prevent the connector body located at the end of the loading trough 21 from sliding directly after the track changing groove 321 leaves the loading trough 21, a baffle 35 is set on the track changing plate 32, when the unloading end of the track changing groove 321 is aligned with the loading end of the processing track 4, the baffle 35 is blocked at the unloading end of the loading track 2, and when the track changing groove 321 leaves the loading trough 21, the baffle 35 moves to the end of the loading trough 21 to block the loading trough 21.

[0040] refer to Figure 3 , Figure 8 and Fig. 9As shown, the needle row installation mechanism 6 includes a needle row feeding plate 61, a needle row receiving plate 62, a top plate 63, a second driving assembly (the second driving assembly is a second cylinder) and a third driving assembly (the third driving assembly is a third cylinder). One end of the needle row feeding plate 61 is located below the processing track 4. A plurality of first needle row grooves 611 are arranged in parallel on the top surface of the needle row feeding plate 61. The end of the needle row feeding plate 61 is externally connected to a vibrating feeding device, which continuously vibrates the needle row onto the needle row feeding plate 61 through vibration, and the needle row that falls into the first needle row groove 611 is transported to the needle row receiving plate 62. The top surface of the receiving plate 62 is provided with a plurality of second needle row grooves 621 corresponding to the first needle row grooves 611 in parallel, and the top plate 63 is provided on the top surface of the needle row receiving plate 62, and the needle row receiving plate 62 is provided in the direction opposite to the conveying groove 41; the second driving component is used to drive the needle row receiving plate 62 to do lifting movement (the needle row mounting mechanism 6 also includes a base 64 provided on the machine table 1, and a guide rail 65 is vertically provided on the base 64, and the needle row receiving plate 62 is slidably provided on the guide rail 65, and the lifting and lowering of the needle row receiving plate 62 is guided by the guide rail 65 to improve the processing accuracy ), the third driving assembly is used to drive the top plate 63 to slide on the top surface of the pin row receiving plate 62 toward one side of the processing track 4, so that the pins on the pin row receiving plate 62 are synchronously pushed toward one side of the processing track 4. In this way, when the connector body is placed at the pin row mounting mechanism 6, the second driving assembly drives the pin row receiving plate 62 to descend to align with the pin row loading plate 61, so that the pins on the pin row loading plate 61 are moved to the pin row receiving plate 62 (in order to facilitate the positioning of the pins, a second pin row groove 621 is provided on the pin row receiving plate 62, and a first pin row groove is provided on the pin row loading plate 61 611, the needle on the corresponding first needle row groove 611 moves to the corresponding second needle row groove 621, at this time, the part of the needle row protrudes from the top surface of the needle row material plate 62, and then the second driving component drives the needle row material plate 62 to move upward to the height of the needle row pin insertion, and the third driving component drives the top plate 63 to slide on the top surface of the needle row material plate 62 toward one side of the processing track 4, so that the needle row located on the needle row material plate 62 is synchronously pushed toward one side of the processing track 4 until it is inserted into the corresponding pin insertion side of the connector body, and the two needle row installation mechanisms 6 respectively insert the two rows of needle row pins in parallel on the connector body.

[0041] refer to Figure 2 and Fig.10As shown, the pin header re-pressing mechanism 7 includes a top head 71 and a driving cylinder 72. The driving cylinder 72 is arranged on the machine table 1. The top head 71 is located in the direction opposite to the track changing groove 321. The top head 71 is arranged at the output end of the driving cylinder 72. The driving cylinder 72 is used to drive the top head 71 to move toward the side of the track changing groove 321. In order to prevent the pin header installation mechanism 6 from failing to firmly insert the pin header into the connector body, when the connector body with the double-row pin header inserted is placed at the pin header re-pressing mechanism 7, the fourth driving component drives the top head 71 to move toward the side of the connector body on the processing track 4, so as to press the suspended end of the double-row pin header, further compact the double-row pin header on the connector body, and reduce the occurrence of loose insertion.

[0042] refer to Figure 2 and Figure 3 As shown, a mounting frame 8 is provided on the machine 1, and a processing track 4 is provided on one side of the mounting frame 8.

In this way, the processing track 4 is supported by the mounting frame 8. When moving materials, the fifth driving component first drives the synchronous plate 52 to rise (avoiding the connector body on the processing track 4). ), driving the synchronous plate 52 to descend (at this time, the two material shifting plates 53 are respectively placed on the connector body at the first pin row installation mechanism 6 and the connector body at the material track change mechanism 3 close to the loading track 2) and then the sixth driving assembly drives the synchronous plate 52 to slide, so that the two connector bodies are respectively moved to the second pin row installation mechanism 6 and the first pin row installation mechanism 6 (during the movement, the material shifting plate 53 abuts against the end of the connector body), and the connector body after assembling the double-row pin row will be pushed to the end side of the processing track 4 by the subsequent connector body, and when it reaches the pin row re-pressing mechanism 7, it will be re-pressed, and finally slide down from the end of the processing track 4 to complete the assembly. In this way, the position of the connector body is continuously moved, and the connector bodies at different assembly links are synchronously moved, thereby improving the processing efficiency.
