Description

Technical Field

[0001] The present invention relates to the technical field of plug-in pins, and in particular to a plug-in pin for automobiles and an assembly device thereof. Background Art

[0002] Pins are one of the commonly used accessories in automobiles. They are usually welded on circuit boards and plugged into accessories on the car to transmit different signals and control the operation of different parts of the car. With the increasing improvement of advanced automobile safety technology, automobile networking technology, and automobile information technology, more and more signals need to be transmitted by automobiles. In order to meet the usage requirements within the limited installation space, more and more pins are required on a single pin.

[0003] In order to better connect the pins in the prior art, straight pins and curved pins are usually set at the same time to stagger the connection points of the pins. The assembly of the pins usually relies on manual operation and the assembly steps are complicated, which affects the assembly efficiency and easily causes the two types of pins to be bent and deformed repeatedly. The bent and deformed pins not only change the position of the connection point, which easily affects the signal transmission, but also affects their service life. Although automatic assembly equipment for pin parts is also used in the prior art, the pins need to be pressed during the installation process, which is generally suitable for straight pins and is not convenient for pressing bent pins. Summary of the invention

[0004] The object of the present invention is to provide an automotive pin component and an assembly device thereof, which can realize the automatic assembly of the pin component, and during assembly, the bent pins in the pin component are first press-fitted in a straight form, and then bent after the press-fitting is completed, so as to avoid bending and deformation during the press-fitting process, meet the automatic assembly requirements of different types of pins, improve the assembly efficiency of the pin component, ensure the assembly quality of the pin component, and reduce the labor intensity of manual labor.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] An assembly device for automotive pin parts, comprising a first transposition frame arranged vertically, wherein four first extension plates arranged vertically and horizontally are arranged in a circumferential array on the upper end of the first transposition frame, wherein a first clamp is arranged at one end of each first extension plate away from the first transposition frame, and the first transposition frame is positioned and rotated around a vertical axis; an upper shell mechanism, a short needle feeding mechanism, a long needle feeding mechanism and a needle pressing mechanism are arranged in a circumferential array around the first transposition frame, wherein the upper shell mechanism, the short needle feeding mechanism, the long needle feeding mechanism and the needle pressing mechanism are arranged in sequence and correspond to the four first clamps one by one;

[0007] It also includes a second transposition frame arranged on the side of the first transposition frame close to the needle pressing mechanism, the upper end of the second transposition frame is provided with four second extension plates arranged perpendicular to it and horizontally, the second extension plate is provided with a second fixture at one end away from the second transposition frame, and the second transposition frame is positioned and rotated around the vertical axis; the second transposition frame is provided with a material transfer mechanism, a needle bending mechanism, a detection mechanism and a material discharge mechanism in a circular array around the second transposition frame, and the material transfer mechanism, the needle bending mechanism, the detection mechanism and the material discharge mechanism are arranged in sequence and correspond to the four second fixtures one by one;

[0008] The needle pressing mechanism and the material transfer mechanism are respectively located on both sides of the first extension plate at this position, the first clamp corresponding to the needle pressing mechanism and the second clamp corresponding to the material transfer mechanism are located at the same height, and the material transfer mechanism horizontally transfers the pin parts that have completed needle pressing in the first clamp corresponding to the needle pressing mechanism to the second clamp corresponding to the material transfer mechanism.

[0009] By adopting the above technical solution, the upper shell mechanism places the shell of the pin member to be assembled on the first fixture corresponding to it, the first position change frame rotates the first fixture with the shell placed on it to the short pin feeding mechanism, the short pin feeding mechanism initially inserts the short pin, that is, the straight pin in the pin member, into the shell, the first position change frame continues to rotate and rotates the first fixture that has completed the short pin placement to the long pin feeding mechanism, the long pin feeding mechanism initially inserts the long pin, that is, the bent pin in the pin member, into the shell in a vertical form. The first position change frame continues to rotate and rotates the first fixture that has completed the long pin placement to the pin pressing mechanism, the pin pressing mechanism synchronously presses the short pin and the long pin to achieve the press-fitting of the pin and the shell.

[0010] After the needle pressing is completed, the material transfer mechanism will horizontally transfer the pin piece that has completed the needle pressing in the first clamp corresponding to the needle pressing mechanism to the second clamp corresponding to the material transfer mechanism, and then the second position transfer frame will rotate the second clamp to correspond to the needle bending mechanism, and the needle bending mechanism will bend the vertical pin into the required bent pin; then the second position transfer frame will rotate the second clamp to the detection mechanism, and the detection mechanism will detect the straight pin and the bent pin to determine whether the vertical and horizontal sections of the straight pin and the bent pin are bent, and finally the second position transfer frame will rotate the pin piece that has completed the detection to the unloading mechanism for unloading.

[0011] In the present invention, during the rotation of the first transposition frame, the upper shell mechanism, the short pin feeding mechanism, the long pin feeding mechanism and the pin pressing mechanism work simultaneously, and during the rotation of the second transposition frame, the material transfer mechanism, the needle bending mechanism, the detection mechanism and the material discharge mechanism work simultaneously. When the first transposition frame and the second transposition frame rotate one circle, the upper shell, short pin feeding, long pin feeding, pin pressing, material transfer, long pin bending, detection and material discharge of a pin part are completed. This reciprocating process realizes the automatic assembly of the pin part, and during the assembly, the bent pin in the pin part is first inserted and pressed in the form of a straight long pin, and then bent by the needle bending mechanism after complete pressing, so as to avoid bending and deformation of the bent pin during the pin pressing process, meet the synchronous pin pressing of the straight pin and the bent pin, improve the assembly efficiency of the pin part, ensure the assembly quality of the pin part, and reduce the labor intensity.

When the needle is removed, the electromagnetic suction block is powered off, and under the action of the needle removal spring, the two needle removal clamps slide close to each other and the end of the guide block away from the needle removal clamp is always located in the guide groove.

As the needle pressing seat continues to move downward, the square plug is pressed vertically downward, so that the elastic ring on the outer periphery of the square plug is inserted into the slot in the square slot, thereby realizing the press-fitting of the short needle / long needle.

The first fixture corresponding to the needle pressing mechanism and the flip block in the second fixture corresponding to the transfer mechanism are both rotated to a horizontal state, and the transfer plate drives the transfer lever to move as a whole toward the second transposition frame, and the pin plug in the first fixture is horizontally transferred to the second fixture, so that the flip block, transfer plate, and transfer lever are reset after the pin plug is transferred.

[0029] Further, the needle bending mechanism includes a needle bending frame, the needle bending frame is provided with a needle bending seat which slides along the length direction of a second extension plate corresponding to the needle bending mechanism, a needle bending plate is vertically slidably mounted on the needle bending seat, two groups of needle bending assemblies are symmetrically arranged on the needle bending plate, and the two groups of needle bending assemblies are relatively horizontally slidably mounted on the needle bending plate along a direction perpendicular to the sliding direction of the needle bending seat; the needle bending assembly includes a needle bending block which is slidably mounted on the needle bending plate along a direction perpendicular to the sliding direction of the needle bending seat, an adjustment plate which is arranged with an axis along the sliding direction of the needle bending seat and is positioned and rotatably mounted on the needle bending block, two needle bending axes are symmetrically arranged on the adjustment plate, the two needle bending axes are parallel to the rotation axis of the adjustment plate, the two needle bending axes are slidably mounted on the adjustment plate along the length direction of the adjustment plate, and the rotation axis of the adjustment plate is located on the symmetry plane of the two needle bending axes.

The two bending needle assemblies are horizontally slidably installed on the bending needle plate along a direction perpendicular to the sliding direction of the bending needle seat through the bending needle block, and the two bending needle shafts are slidably installed on the adjustment plate along the length direction of the adjustment plate. The position of the two bending needle assemblies and the distance between the two bending needle shafts can be adjusted according to the distance between the two rows of long needles, the thickness of the long needles, etc., to meet the bending processing of long needles of different specifications and improve the scope of application.

[0031] Further, the detection mechanism includes a vertically arranged detection frame, the detection frame is provided with a detection seat which slides along the length direction of a second extension plate corresponding to the detection mechanism, the lower end surface of the detection seat is vertically slidably mounted with a horizontally arranged horizontal detection plate, the lower end surface of the horizontal detection plate is provided with a horizontally arranged first detection sensor; the lower end surface of the detection seat is also provided with vertical detection plates located on both sides of the horizontal detection plate, the two vertical detection plates are relatively horizontally slidably mounted on the detection seat in a direction perpendicular to the sliding direction of the detection seat, and a vertically arranged second detection sensor is provided on the side where the two vertical detection plates are close to each other.

[0032] By adopting the above technical solution, when the second transposition frame drives the second clamp that completes the bending of the pin to rotate to the detection mechanism, the detection seat as a whole slides along the length direction of the corresponding second extension plate to the top of the corresponding second clamp, and the horizontal detection plate slides vertically downward to abut against the end of the short pin, that is, the straight pin. The first detection sensor detects whether the upper end heights of several straight pins are consistent to determine whether the straight pins are bent. At the same time, the vertical detection plates slide close to each other and abut against the side ends of the bent pins, that is, the upper ends of the original long pins. The second detection sensor detects whether the side ends of several bent pins are consistent in height and distance to determine whether the bent pins are bent. In this way, the synchronous detection of straight pins and bent pins is achieved, the assembly quality of the pin parts is determined, and the detection efficiency is effectively improved.

[0033] A plug-in component for automobiles, comprising a shell, wherein two rows of straight plug-ins are arranged on the shell along the width direction thereof, and a plurality of straight plug-ins in each row are arranged in an array along the length direction of the shell; the shell is also provided with a bent plug-in pin located on the side away from each other of the two rows of straight plug-ins, and a plurality of bent plug-ins in each row are also arranged in an array along the length direction of the shell and correspond one to one with the straight plug-ins on one side thereof; the bent plug-in pin is in an L-shaped structure with an opening downward, and has an arc transition at the bending part thereof, and the bending directions of the bent plug-ins in the two rows are opposite; the upper ends of the straight plug-ins are higher than the upper ends of the bent plug-ins, and the end faces of the straight plug-ins and the bent plug-ins at one end away from the shell are both processed with an arc; square plug-in blocks are arranged at the bottoms of a plurality of the straight plug-ins and the bent pins, and a plurality of square slots corresponding one to one with the square plug-in blocks are arranged in a rectangular array on the upper end face of the shell; an elastic ring close to the upper end of the square plug-in block is arranged around the outer circumference thereof, and a card slot cooperating with the elastic ring is arranged in the square plug-in block.

[0034] By adopting the above technical solution, under the cooperation of the square plug block and the direction slot, the stability of the straight pins and the curved pins when they are loaded as short pins and long pins in a vertical state is facilitated, and the shaking and displacement of the short pins / long pins during the rotation of the first transposition frame is avoided, which affects the subsequent pressing of the pins. In addition, during the pressing process, the square plug block can be squeezed to achieve press-fitting, avoiding direct squeezing of the short pins / long pins to cause them to bend and deform. Under the cooperation of the elastic ring and the card slot, the square plug block is fixed in the direction slot to ensure the stability of the installation of the straight pins and the curved pins, and the elastic ring is close to the upper end of the square plug block to ensure that when the straight pins and the curved pins are loaded as short pins and long pins in a vertical state, the lower end of the square plug block has enough depth to be placed in the corresponding square slot to ensure its placement stability. Among them, the pin member includes two rows of straight pins and two rows of curved pins, and the upper end of the straight pin is higher than the upper end of the curved pin, which increases the connection points of the pin member and facilitates its connection, meeting its use requirements. The bending directions of the two rows of bent pins are opposite, which prevents the ends from being close to each other and causes interference, and facilitates the bending operation during assembly. When the bent pins in the present invention are assembled using an assembly device, the bent pins are first loaded and pressed as long pins in a straight state, and then bent into a bent state, which effectively prevents the bent pins from being bent and deformed during the pressing process, thereby ensuring the assembly quality of the pin parts.

[0051] Among them, Figure 1As shown, the upper end of the straight pin 2 is higher than the upper end of the bent pin 3, and the end faces of the straight pin 2 and the bent pin 3 away from the housing 1 are both arc-shaped, so that the pin member increases the connection points of the pin member and facilitates the connection of the ends of the straight pin 2 and the bent pin 3 with the outside, meeting its use requirements. The bending directions of the two rows of bent pins 3 are opposite, avoiding interference between their ends when close together, and facilitating the bending operation during assembly.

[0052] like Figure 1 As shown, in order to facilitate the assembly of the straight pins 2 and the curved pins, square plug blocks 4 are provided at the bottom of the straight pins 2 and the curved pins 3, and a plurality of square slots 5 corresponding to the square plug blocks 4 are provided in a rectangular array on the upper end surface of the housing 1, and an elastic ring 6 is provided around the outer circumference of the square plug block 4 near the top thereof, and a slot 7 cooperating with the elastic ring 6 is provided inside the square plug block 4.

[0053] like Figure 1 As shown, under the cooperation of the square plug block 4 and the square slot 5, and the cooperation of the elastic ring 6 and the slot 7, the straight pin 2 and the curved pin 3 are detachably fixedly installed. In particular, under the cooperation of the square plug block 4 and the direction slot, and the cooperation of the elastic ring 6 close to the top of the square plug block 4, it is ensured that when the straight pin 2 and the curved pin 3 are both loaded in the form of short pins and long pins in a vertical state, the lower end of the square plug block 4 has sufficient depth to be located in the square slot 5, thereby ensuring the stability of loading and placement. In the process of pressing the pins, the elastic ring 6 can be quickly pressed into the slot 7 by squeezing the square plug block 4, avoiding direct squeezing of the short pin / long pin to cause it to bend and deform, thereby reducing the difficulty of pressing.

[0054] An assembly device for automotive pin parts, used for assembling the above automotive pin parts, such as Figure 2 As shown, it specifically includes a first transposition frame 8 which is vertically arranged and positioned and rotated around a vertical axis. Four first extension plates 9 which are perpendicular to and horizontally arranged are arranged in a circumferential array on the upper end of the first transposition frame 8. A first fixture 10 is arranged at one end of each first extension plate 9 away from the first transposition frame 8. An upper shell mechanism 15, a short needle feeding mechanism 20, a long needle feeding mechanism 35 and a pressing needle mechanism 43 are arranged in a circumferential array around the first transposition frame 8. The upper shell mechanism 15, the short needle feeding mechanism 20, the long needle feeding mechanism 35 and the pressing needle mechanism 43 are arranged in sequence and correspond to the four first fixtures 10 one by one.

[0055] like Figure 2As shown, it also includes a second transposition frame 49 which is arranged on the side of the first transposition frame 8 close to the needle pressing mechanism 43 and is positioned and rotated around the vertical axis. Four second extension plates 50 which are arranged perpendicular to and horizontally therefrom are arranged in a circumferential array on the upper end of the second transposition frame 49. A second fixture 51 is arranged at one end of the second extension plate 50 which is away from the second transposition frame 49. A material transfer mechanism 52, a needle bending mechanism 56, a detection mechanism 64 and a material discharge mechanism 71 are arranged in a circumferential array around the second transposition frame 49. The material transfer mechanism 52, the needle bending mechanism 56, the detection mechanism 64 and the material discharge mechanism 71 are arranged in sequence and correspond to the four second fixtures 51 one by one.

[0056] Among them, Figure 2 As shown, the needle pressing mechanism 43 and the material transfer mechanism 52 are respectively located on both sides of the first extension plate 9 at the position, the first clamp 10 corresponding to the needle pressing mechanism 43 and the second clamp 51 corresponding to the material transfer mechanism 52 are located at the same height, and the material transfer mechanism 52 horizontally transfers the needle inserting parts that have completed the needle pressing in the first clamp 10 corresponding to the needle pressing mechanism 43 to the second clamp 51 corresponding to the material transfer mechanism 52. In addition, a controller 77 is also provided on one side of the first reversing frame or the second reversing frame. The controller 77 controls the automatic work and linkage of each mechanism in the device by adopting automatic control technology such as PLC. The automatic control technology such as PLC is a prior art and will not be described in detail.

[0057] like Figure 2 As shown, when the present invention is working, the upper shell mechanism 15 places the shell 1 of the pin member to be assembled on the first fixture 10 corresponding thereto, the first position change frame 8 rotates to rotate the first fixture 10 with the shell 1 placed thereon to the short pin feeding mechanism 20, the short pin feeding mechanism 20 preliminarily inserts the short pin, that is, the straight pin 2 in the pin member, into the shell 1, the first position change frame 8 continues to rotate to rotate the first fixture 10 after the short pin is placed to the long pin feeding mechanism 35, the long pin feeding mechanism 35 preliminarily inserts the long pin, that is, the bent pin 3 in the pin member into the shell 1 in a vertical form. The first position change frame 8 continues to rotate to rotate the first fixture 10 after the long pin is placed to the pin pressing mechanism 43, the pin pressing mechanism 43 performs synchronous pin pressing on the short pin and the long pin, and realizes the press-fitting of the pin and the shell 1.

[0058] like Figure 2As shown, after the needle pressing is completed, the material transfer mechanism 52 horizontally transfers the pin piece that has completed the needle pressing in the first fixture 10 corresponding to the needle pressing mechanism 43 to the second fixture 51 corresponding to the material transfer mechanism 52, and then the second position change frame 49 rotates to rotate the second fixture 51 to correspond to the needle bending mechanism 56, and the needle bending mechanism 56 bends the vertical pin into the required bent pin 3; then the second position change frame 49 rotates to rotate the second fixture 51 to the detection mechanism 64, and the detection mechanism 64 detects the straight pin 2 and the bent pin 3 to determine whether the vertical section and the horizontal section of the straight pin 2 and the bent pin 3 are bent, and finally the second position change frame 49 rotates to rotate the pin piece that has completed the detection to the unloading mechanism 71 for unloading.

[0059] like Figure 2 As shown, in the present invention, during the rotation of the first transposition frame 8, the upper shell mechanism 15, the short needle loading mechanism 20, the long needle loading mechanism 35 and the needle pressing mechanism 43 work simultaneously, and during the rotation of the second transposition frame 49, the material transfer mechanism 52, the needle bending mechanism 56, the detection mechanism 64 and the material unloading mechanism 71 work simultaneously. When the first transposition frame 8 and the second transposition frame 49 rotate one circle, the upper shell, short needle loading, long needle loading, needle pressing, material transfer, long needle bending, detection and unloading of a pin part are completed.

[0060] like Figure 2 As shown, the process is repeated in this way to realize the automatic assembly of the pin parts. During assembly, the bent pin 3 in the pin part is first inserted and pressed in the form of a straight long pin. After complete pressing, it is bent by the needle bending mechanism 56 to avoid bending and deformation of the bent pin 3 during the pressing process, thereby meeting the synchronous pressing of the straight pin 2 and the bent pin 3, improving the assembly efficiency of the pin parts, ensuring the assembly quality of the pin parts, and reducing the labor intensity.

[0061] like Figure 2 As shown, the specific structures of the first clamp 10, the second clamp 51, the upper shell mechanism 15, the short needle feeding mechanism 20, the long needle feeding mechanism 35, the needle pressing mechanism 43, the material transfer mechanism 52, the needle bending mechanism 56, the detection mechanism 64 and the material discharge mechanism 71 are described in detail below. Among them, unless otherwise specified, the following uses a motor to realize the rotation drive, a telescopic cylinder to realize horizontal telescopic, and a lifting cylinder to realize vertical lifting. No more details are given in the text, and only a simple diagram is given in the accompanying drawings. The three vibration disks used in this embodiment are the same as those in the prior art, and only a simple diagram is given in the figure.

[0062] like Figure 2 and Figure 3As shown, the first clamp 10 and the second clamp 51 both include a left clamp block 11 and a right clamp block 12 which are symmetrically arranged along the length direction of the corresponding first extension plate 9 / second extension plate 50, the left clamp block 11 and the right clamp block 12 are in an L-shaped structure with their openings facing upward and their openings are located on the side close to each other, the upper end of the shell 1 of the pin member is higher than the upper ends of the left clamp block 11 and the right clamp block 12, and the left clamp block 11 and the right clamp block 12 are installed on the corresponding first extension plate 9 / second extension plate 50 in a horizontal relative sliding manner along a direction perpendicular to the corresponding first extension plate 9 / second extension plate 50.

[0063] like Figure 2 and Figure 3 As shown, a limit block 13 is provided between the ends of the left clamp block 11 and the right clamp block 12 close to the corresponding first transposition frame 8 / second transposition frame 49, the upper end height of the limit block 13 is not higher than the height of the left clamp block 11 and the right clamp block 12, and the limit block 13 is slidably installed on the corresponding first extension plate 9 / second extension plate 50 along the length direction of the left clamp block 11. In addition, a flip block 14 is provided at the end of the left clamp block 11 or the right clamp block 12 away from the limit block 13 and is rotatably connected thereto, and the rotation axis of the flip block 14 is arranged along the width direction of the corresponding first extension plate 9 / second extension plate 50. When the flip block 14 rotates to a vertical upward state, its rotation axis is located at its lower end, and when the flip block 14 rotates to a horizontal state, its upper end surface is flush with the lower end surface of the housing 1 of the pin insert in the corresponding first clamp 10 / second clamp 51.

[0064] like Figure 3 As shown, the left clamp block 11, the right clamp block 12, the limit block 13 and the flip block 14 in the vertical state constitute a cavity with four sides for placing the housing 1 of the pin component. The left clamp block 11 and the right clamp block 12 can slide against each other to adjust the distance between them, adapt to housings 1 of different widths and ensure the stability of the housing 1. Figure 2 and Figure 3 As shown, the limit block 13 sliding along the corresponding first extension plate 9 / second extension plate 50 can not only slide to adjust the distance between it and the flip block 14 to adapt to different lengths of the housing 1, but also when the material is unloaded at the subsequent unloading mechanism 71, the pin member can be directly pushed out of the second clamp 51 through the limit block 13, simplifying the structure of the unloading mechanism 71. The eccentrically rotating flip block 14 can be rotated to a horizontal state, and the upper end of the housing 1 of the pin member is higher than the upper ends of the left clamp block 11 and the right clamp block 12, which is convenient for quickly pushing the pin member in the first clamp 10 at the pin pressing mechanism 43 directly horizontally to the second clamp 51 at the transfer mechanism 52, and convenient for fast unloading at the unloading mechanism 71.

[0065] like Figure 2 and Figure 3As shown, the upper shell mechanism 15 includes an upper shell bracket 16 and an upper shell vibration plate 17 mounted on the upper shell bracket 16. The outlet of the upper shell vibration plate 17 is connected to an upper shell channel 18, and the width of the upper shell channel 18 is adapted to the width of the shell 1 of the pin member. The upper shell bracket 16 is also provided with an upper shell clamp 19 located on the outlet side of the upper shell channel 18.

Among them, the upper shell clamp 19 is a pneumatic clamp, and its structure and working principle are the same as those in the prior art. It can grasp and lift the grasped object, and is only briefly illustrated in the figure.

[0068] like Figure 4As shown, the short needle vibration plate 22 vibrates to arrange the short needles neatly on the two short needle channels 23, and the short needle partition rods 24 at the outlet of the short needle channel 23 are rotated to a horizontal state in turn to separate the several short needles, so that the distance between the square plug block 4 at the bottom of the short needle and the square slot 5 on the housing 1 corresponds one by one. The short needle loading assembly 25 works, and the short needle loading seat 27 drives the several needle cylinders 28 to slide vertically downward, so that the needle cylinders 28 and the several short needles correspond one by one, and the short needle loading seat 27 moves vertically upward, and the needle cylinders 28 are used to lift the several short needles vertically upward to separate from the short needle channel 23, and the short needles are taken out. The short needle loading plate 26 slides as a whole along the length direction of the first extension plate 9 corresponding to it, and the short needle loading seat 27 is moved to be directly above the first clamp 10 corresponding to the short needle loading mechanism 20. The short needle loading seat 27 slides vertically downward, and the short needles in the syringe 28 are placed one by one into the square slots 5 on the shell 1 in the first clamp 10 to complete the loading of the short needles.

[0069] like Figure 2 and Figure 5 As shown, the structures and working principles of the long needle feeding mechanism 35 and the short needle feeding mechanism 20 are basically similar, specifically including a long needle feeding bracket 36 and a long needle vibration disk 37 installed on the long needle feeding bracket 36, and the outlet of the long needle vibration disk 37 is connected to two parallel long needle channels 38, the width of the long needle channel 38 is adapted to the width of the square plug block 4 at the bottom of the bent pin 3 in the pin piece, and the distance between the two long needle channels 38 is adapted to the distance between the two rows of bent pins 3 in the pin piece; the discharge ports of the two long needle channels 38 are arranged along the length direction of the first extension plate 9 corresponding to the long needle feeding mechanism 35, and the discharge ports of the two long needle channels 38 are provided with a plurality of long needle partition rods 39 along the length direction thereof, one end of the long needle partition rod 39 is eccentrically rotatably installed on the long needle channel 38, and its rotation axis is horizontally arranged along the length direction perpendicular to the discharge port of the long needle channel 38.

[0070] like Figure 5 As shown, a long needle loading assembly 40 is also provided at the discharge port of the two long needle channels 38. The long needle loading assembly 40 includes a long needle loading plate 41 slidably mounted on the long needle loading bracket 36 along the length direction of the first extension plate 9 corresponding to the long needle loading mechanism 35, and a long needle loading seat 42 arranged along the sliding direction of the long needle loading plate 41 is vertically slidably mounted at the lower end of the long needle loading plate 41, and two groups of syringe barrels 28 corresponding to the two long needle channels 38 are provided on the lower end surface of the long needle loading seat 42 along its width direction, and each group of syringe barrels 28 is provided with a plurality of syringe barrels in an array along the length direction of the long needle loading seat 42.

[0071] Likewise, if Figure 5As shown, the long needle vibration plate 37 vibrates to arrange the long needles neatly on the two long needle channels 38, and the long needle partition rods 39 at the outlet of the long needle channel 38 are rotated to a horizontal state in turn to separate the long needles, so that the distance between the square plug block 4 at the bottom of the long needle and the square slot 5 on the housing 1 corresponds one by one. The long needle loading assembly 40 works, and the long needle loading seat 42 drives the several needle cylinders 28 to slide vertically downward, so that the needle cylinders 28 and the several long needles correspond one by one, and the long needle loading seat 42 moves vertically upward, and the needle cylinders 28 are used to lift the several long needles vertically upward to separate them from the long needle channel 38, completing the long needle loading. The long needle loading plate 41 slides as a whole along the length direction of the first extension plate 9 corresponding to it, and the long needle loading seat 42 is moved to be directly above the first clamp 10 corresponding to the long needle loading mechanism 35. The long needle loading seat 42 slides vertically downward, and the long needles in the syringe 28 are placed one by one into the square slots 5 on the shell 1 in the first clamp 10 to complete the loading of the long needles.

[0072] like Figure 4 and Figure 5 As shown, in this embodiment, the needle-taking cylinder 28 in the short needle loading assembly 25 and the needle-taking cylinder 28 in the long needle loading assembly 40 have the same structure. Specifically, two needle-taking clamps 29 are arranged symmetrically about the vertical plane where the axis thereof is located in the needle-taking cylinder 28, and a plurality of elastic protrusions 30 are arranged in a rectangular array on the side where the two needle-taking clamps 29 are close to each other; the two needle-taking clamps 29 are radially slidably installed in the needle-taking cylinder 28, and a guide block 31 is arranged along the sliding direction of the two needle-taking clamps 29 on the side away from each other. The inner wall of the needle-taking cylinder 28 is provided with a guide groove 32 arranged along the sliding direction of the needle-taking clamps 29, and the guide block 31 is slidably installed in the corresponding guide groove 32. A needle-taking spring 33 is connected between the bottom of the guide groove 32 and the end of the guide block 31 away from the needle-taking clamp 29, and the bottom of the guide groove 32 and the end of the guide block 31 away from the needle-taking clamp 29 are also provided with electromagnetic suction blocks 34 that cooperate with each other. In normal state, the electromagnetic suction block 34 is energized for adsorption, and the two needle removal clamps 29 move away from each other. When the needle is removed, the electromagnetic suction block 34 is de-energized, and under the action of the needle removal spring 33, the two needle removal clamps 29 slide towards each other and the end of the guide block 31 away from the needle removal clamp 29 is always located in the guide groove 32.

[0073] like Figure 4 and Figure 5As shown, when the needle cylinder 28 moves vertically downward to remove the needle, the electromagnetic suction block 34 is powered on to absorb, and the two needle-removing clips 29 move away from each other. When the corresponding short needle / long needle enters the needle cylinder 28 to remove the needle, the electromagnetic suction block 34 is powered off, and the two needle-removing clips 29 slide close to each other under the action of the needle-removing spring 33. The two needle-removing clips 29 clamp and fix the short needle / long needle to achieve needle removal. When the needle cylinder 28 moves vertically downward to the corresponding first clamp 10 to place the needle, after the square plug-in block 4 below the short needle / long needle is placed in the corresponding square slot 5 on the housing 1, the electromagnetic suction block 34 is powered on to absorb, and the two needle-removing clips 29 move away from each other to release the support and fixation of the short needle / long needle. After the needle cylinder 28 is reset upward, it can be separated from the short needle / long needle to complete the needle placement.

[0074] like Figure 2 and Figure 6 As shown, the needle pressing mechanism 43 includes a vertically arranged needle pressing frame 44, on which a needle pressing plate 45 is arranged. The needle pressing plate 45 is slidably mounted on the needle pressing frame 44 along a horizontal direction perpendicular to the length direction of the first extension plate 9 corresponding to the needle pressing mechanism 43, and the needle pressing plate 45 can slide to the top of the first clamp 10 corresponding to the needle pressing mechanism 43. A needle pressing seat 46 is vertically slidably mounted on the lower end surface of the needle pressing plate 45, and a plurality of needle pressing cylinders 47 are arranged in a rectangular array on the lower end surface of the needle pressing seat 46. The bottom cross-sections of the plurality of needle pressing cylinders 47 are matched one by one with the plurality of square plug blocks 4 on the pin inserting member in the first clamp 10 corresponding to the needle pressing mechanism 43, and a needle hole 48 coaxial with the needle pressing cylinder 47 is arranged inside the needle pressing cylinder 47.

[0075] like Figure 2 and Figure 6 As shown, after the first fixture 10 for placing the long needle is rotated to correspond to the needle pressing mechanism 43, the needle pressing plate 45 slides as a whole in a direction perpendicular to the corresponding first extension plate 9 until the needle pressing seat 46 moves to just above the corresponding first fixture 10, and the needle pressing seat 46 drives a number of needle pressing cylinders 47 to slide vertically downward, and the short needle / long needle enters the needle hole 48 in the corresponding needle pressing cylinder 47, and the lower end of the needle pressing cylinder 47 abuts against the square plug 4 at the bottom of the short needle / long needle. As the needle pressing seat 46 continues to move downward, the square plug 4 is pressed vertically downward, so that the elastic ring 6 on the outer periphery of the square plug 4 is inserted into the card slot 7 in the square slot 5, to realize the press-fitting of the short needle / long needle. After the press-fitting is completed, the needle pressing seat 46 and the needle pressing plate 45 can be reset one by one.

[0076] like Figure 2 and Figure 6As shown, the material transfer mechanism 52 includes a material transfer rack 53, on which is provided a material transfer plate 54 which is horizontally and perpendicularly arranged in the length direction of the second extension plate 50 corresponding to the material transfer mechanism 52, and one end of the material transfer plate 54 close to the material transfer rack 53 is slidably installed on the material transfer rack 53 along the length direction of the corresponding second extension plate 50; the end of the material transfer plate 54 away from the material transfer rack 53 is provided with a material transfer lever 55 which is located above the first fixture 10 corresponding to the needle pressing mechanism 43 and corresponds to the shell 1 of the pin plug in the first fixture 10, and the material transfer lever 55 is slidably installed on the material transfer plate 54 along the length direction of the material transfer plate 54.

[0077] like Figure 2 and Figure 6 As shown, after the needle pressing mechanism 43 completes the needle pressing, the material transfer plate 54 slides along the length direction of the corresponding second extension plate 50 to cooperate with the material transfer lever 55 to slide along the length direction of the material transfer plate 54, and the material transfer lever 55 is moved to the side of the first fixture 10 corresponding to the needle pressing mechanism 43 close to the corresponding first extension plate 9, and the material transfer lever 55 cooperates with the pin housing 1 in the first fixture 10. The first fixture 10 corresponding to the needle pressing mechanism 43 and the flip block 14 in the second fixture 51 corresponding to the material transfer mechanism 52 are both rotated to a horizontal state and their active ends are close to each other. The material transfer plate 54 drives the material transfer lever 55 to move as a whole toward the second transposition frame 49, and the pin in the first fixture 10 is horizontally transferred to the second fixture 51, so that the flip block 14, the material transfer plate 54, and the material transfer lever 55 can be reset after the pin transfer.

[0078] like Figure 2 and Figure 7 As shown, the needle bending mechanism 56 includes a needle bending frame 57, on which is provided a needle bending seat 58 which slides along the length direction of the second extension plate 50 corresponding to the needle bending mechanism 56, and on which is vertically slidably mounted a needle bending plate 59, on which is symmetrically arranged two groups of needle bending assemblies 60, and the two groups of needle bending assemblies 60 are relatively horizontally slidably mounted on the needle bending plate 59 along a direction perpendicular to the sliding direction of the needle bending seat 58; the needle bending assembly 60 includes a needle bending block 61 which is slidably mounted on the needle bending plate 59 along a direction perpendicular to the sliding direction of the needle bending seat 58, on which is positioned and rotatably mounted an adjustment plate 62 whose axis is arranged along the sliding direction of the needle bending seat 58, and on which is symmetrically arranged two needle bending shafts 63 which are parallel to the rotation axis of the adjustment plate 62, and which are slidably mounted on the adjustment plate 62 along the length direction of the adjustment plate 62, and the rotation axis of the adjustment plate 62 is located on the symmetry plane of the two needle bending shafts 63. Among them, the sliding adjustment of the two bending needle shafts 63 in each group of bending needle assemblies 60 is adjusted by screws that are threadedly connected to the base and have opposite thread rotation directions. This is the existing technology and is only briefly illustrated in the figure.

[0079] like Figure 2 and Figure 7As shown, when the second position-changing frame 49 drives the second clamp 51 to rotate to correspond to the bending needle mechanism 56, the bending needle seat 58 as a whole slides along the length direction of the corresponding second extension plate 50, so that the two rows of long needles enter between the two bending needle shafts 63 in the two groups of bending needle assemblies 60 respectively, and the adjustment plate 62 in the two groups of bending needle assemblies 60 is positioned and rotated, and the two bending needle shafts 63 on the adjustment plate 62 bend the long needles into the bent insertion needles 3, thereby realizing the bending needle operation of the long needles. Among them, the bending needle plate 59 is vertically slidably installed on the bending needle seat 58, and the height of the bending point of the long needle can be adjusted by adjusting the height of the bending needle plate 59. The two bending needle assemblies 60 are installed on the bending needle plate 59 by sliding horizontally along the sliding direction perpendicular to the bending needle seat 58 through the bending needle block 61, and the two bending needle shafts 63 are installed on the adjusting plate 62 by sliding along the length direction of the adjusting plate 62. The positions of the two bending needle assemblies 60 and the distance between the two bending needle shafts 63 can be adjusted according to the distance between the two rows of long needles, the thickness of the long needles, etc., to meet the bending processing of long needles of different specifications and improve the scope of application.

[0080] like Figure 2 and Figure 8 As shown, the detection mechanism 64 includes a vertically arranged detection frame 65, on which a detection seat 66 is provided that slides along the length direction of the second extension plate 50 corresponding to the detection mechanism 64, and a horizontally arranged horizontal detection plate 67 is vertically slidably mounted on the lower end surface of the detection seat 66, and a horizontally arranged first detection sensor 68 is provided on the lower end surface of the horizontal detection plate 67. Vertical detection plates 69 located on both sides of the horizontal detection plate 67 and vertically arranged are also provided on the lower end surface of the detection seat 66, and the two vertical detection plates 69 are relatively horizontally slidably mounted on the detection seat 66 in a direction perpendicular to the sliding direction of the detection seat 66, and a vertically arranged second detection sensor 70 is provided on the side where the two vertical detection plates 69 are close to each other.

[0081] like Figure 2 and Figure 8 As shown, when the second transposition frame 49 drives the second clamp 51 that has completed the bending of the pin to rotate to the detection mechanism 64, the detection seat 66 as a whole slides along the length direction of the corresponding second extension plate 50 to the top of the corresponding second clamp 51, and the horizontal detection plate 67 slides vertically downward to abut against the end of the short pin, that is, the straight pin 2. The first detection sensor 68 detects whether the upper end heights of several straight pins 2 are consistent to determine whether the straight pins 2 are bent. At the same time, the vertical detection plates 69 slide close to each other and abut against the side ends of the bent pins 3, that is, the upper ends of the original long pins. The second detection sensor 70 detects whether the side end heights and distances of several bent pins 3 are consistent to determine whether the bent pins 3 are bent. In this way, the straight pins 2 and the bent pins 3 are synchronously detected, the assembly quality of the pin parts is determined, and the detection efficiency is effectively improved.

[0082] like Figure 2 and Fig. 9As shown, the unloading mechanism 71 includes an unloading frame 72, on which is provided an unloading seat 73, which is slidably mounted on the unloading frame 72 along the width direction of the first extension plate 9 corresponding to the unloading mechanism 71. An unloading guide groove 74 is provided on the unloading seat 73, and the unloading guide groove 74 is rotatably mounted on the unloading seat 73 at one end close to the second clamp 51 corresponding to the unloading mechanism 71, and its rotation axis is arranged along the width direction of the first extension plate 9 corresponding to the unloading mechanism 71. A finished product basket 75 and a waste basket 76 arranged in parallel along the sliding direction of the unloading seat 73 are provided below one end of the unloading guide groove 74 away from its rotation axis.

[0083] like Figure 2 and Fig. 9 As shown, the detection mechanism 64 and the unloading mechanism 71 are connected in communication feedback. When the detection mechanism 64 detects that the pin parts are qualified, the unloading seat 73 drives the unloading guide groove 74 to move to the corresponding finished product basket 75. When the detection mechanism 64 detects that the pin parts are unqualified, the unloading seat 73 drives the unloading guide groove 74 to move to the corresponding waste basket 76. The flip block 14 in the second clamp 51 at the unloading mechanism 71 rotates to a horizontal state, and the limit block 13 in the second clamp 51 at the unloading mechanism 71 slides to push the pin parts from the second clamp 51 to the unloading guide groove 74 to realize the unloading of the pin parts. The unloading guide groove 74 slowly rotates from a horizontal state to an inclined state, and the pin parts slide from the unloading guide groove 74 to the corresponding finished product basket 75 or waste basket 76 to realize the classified storage of the pin parts. Among them, the blanking guide groove 74 receives materials in a horizontal state and discharges materials in an inclined state, which prevents the pin parts from falling directly and quickly from the inclined blanking guide groove 74, causing the straight pins 2 or the bent pins 3 to be easily deformed, thereby further ensuring the quality of the pin parts in the blanking stage.

[0084] Working principle and use method of the present invention:

[0085] The upper shell mechanism 15 places the shell 1 of the pin member to be assembled on the first fixture 10 corresponding thereto, and the first position-changing frame 8 rotates the first fixture 10 on which the shell 1 is placed to the short-pin feeding mechanism 20, and the short-pin feeding mechanism 20 preliminarily inserts the short pin, that is, the straight pin 2 in the pin member, into the shell 1, and the first position-changing frame 8 continues to rotate to rotate the first fixture 10 on which the short pin is placed to the long-pin feeding mechanism 35, and the long-pin feeding mechanism 35 preliminarily inserts the long pin, that is, the bent pin 3 in the pin member into the shell 1 in a vertical form. The first position-changing frame 8 continues to rotate to rotate the first fixture 10 on which the long pin is placed to the pin pressing mechanism 43, and the pin pressing mechanism 43 presses the short pin and the long pin synchronously to achieve press-fitting of the pin and the shell 1.

[0086] After the needle pressing is completed, the transfer mechanism 52 horizontally transfers the pin piece that has completed the needle pressing in the first fixture 10 corresponding to the needle pressing mechanism 43 to the second fixture 51 corresponding to the transfer mechanism 52, and then the second position transfer frame 49 rotates the second fixture 51 to correspond to the needle bending mechanism 56, and the needle bending mechanism 56 bends the vertical pin into the required bent pin 3; then the second position transfer frame 49 rotates the second fixture 51 to the detection mechanism 64, and the detection mechanism 64 detects the straight pin 2 and the bent pin 3 to determine whether the vertical and horizontal sections of the straight pin 2 and the bent pin 3 are bent, and finally the second position transfer frame 49 rotates the pin piece that has completed the detection to the unloading mechanism 71 for unloading.

[0087] In the present invention, during the rotation of the first transposition frame 8, the upper shell mechanism 15, the short pin feeding mechanism 20, the long pin feeding mechanism 35 and the pin pressing mechanism 43 work simultaneously, and during the rotation of the second transposition frame 49, the transfer mechanism 52, the needle bending mechanism 56, the detection mechanism 64 and the unloading mechanism 71 work simultaneously. When the first transposition frame 8 and the second transposition frame 49 rotate one circle, the upper shell, short pin feeding, long pin feeding, pin pressing, transfer, long pin bending, detection and unloading of a pin part are completed. In this way, the automatic assembly of the pin part is realized, and during the assembly, the bent pin 3 in the pin part is first inserted and pressed in the form of a straight long pin, and then bent by the needle bending mechanism 56 after complete pressing, so as to avoid bending and deformation of the bent pin 3 during the pin pressing process, meet the synchronous pin pressing of the straight pin 2 and the bent pin 3, improve the assembly efficiency of the pin part, ensure the assembly quality of the pin part, and reduce the labor intensity.
