Description

Technical Field

[0001] The invention belongs to the field of automation equipment, and in particular relates to a connector pin insertion machine. Background Art

[0002] Traditional connector structure, such as Fig.15 As shown, it includes a plastic shell 62 and a plug 63. A pinhole for plugging with the plug 63 is provided on the plastic shell 62. In order to increase the connection firmness between the plug and the shell, a biting mechanism is usually used to bit the plug 63 to form a widened portion 64. The structure of a traditional connector pin insertion machine, such as the Chinese invention patent with the authorization announcement number "CN113067226B" and the name "an automatic production equipment for connectors", includes a frame and a material transfer frame arranged at the upper end of the frame. The material transfer frame is provided with a material transfer mechanism for transferring materials. The frame is provided with a feeding mechanism for inputting the shell, a pin insertion mechanism for inserting the plug into the shell, a biting mechanism, a shaping mechanism, a K-punching mechanism, a bending mechanism, a detection mechanism and a discharging mechanism in sequence on one side of the material transfer frame along the direction of transferring materials. The production steps are as follows: first, the pin needs to be inserted into the shell, then the pin is textured, the width of the pin increases after the texture, and then the pin is shaped so that the widened part of the pin is inserted into the shell to increase the connection strength between the pin and the shell, then the pin outside the shell is K-punched to bend the end of the pin into a specific shape, and finally the pin outside the shell is bent 90 degrees to form a connector. The disadvantages are: 1. Since the pin is first inserted into the shell, then the pin is textured, and finally the pin is shaped so that the widened part of the pin is inserted into the shell, this process usually inserts the pin from the front end of the shell, which easily causes the widened part of the pin to damage the pinhole at the front end of the shell, thereby causing the waterproof performance and the stability of the pin to deteriorate; 2. The stations are arranged side by side, resulting in a very large equipment volume (length) and very poor expandability; 3. Pin leakage is prone to occur. Summary of the invention

DETAILED DESCRIPTION

[0017] Reference Figure 1-Figure 14As shown, the fully automatic connector pin insertion machine of the present invention comprises: a rotary pin transmission mechanism 1, a biting mechanism 2, a plastic shell transmission and pre-pressing mechanism 3 and a pin crimping mechanism 4. The rotary pin transmission mechanism 1 comprises a frame 5, a rotary pin fixture 6 arranged on the frame 5 and a pin vibration plate 14 arranged on one side of the rotary pin fixture 6. The rotary pin fixture 6 comprises a rotating shaft 7, a pin clamping mechanism 8 arranged on the rotating shaft 7 in a four-part manner and a driving mechanism 9 for driving the rotating shaft 7 to rotate in four parts. The pin clamping mechanism 8 comprises a fixed seat 10, a group of clamping fingers 11 rotatably arranged on the fixed seat 10, an elastic member 12 driving the clamping fingers 11 to clamp toward the fixed seat 10 and an opening mechanism 13 for opening the clamping fingers 11. The number of the clamping fingers 11 is determined according to the needs. Usually, one clamping finger 11 completes the assembly of one connector. In this example, there are five clamping fingers 11, that is, five connectors can be assembled at one time. The elastic member 12 is ideally a spring, but it can also be replaced by an elastic member such as a spring. The front end of the fixed seat 10 is provided with a group of pinholes 15 connected to the pin vibration disk 14, and the rear end is provided with a slot 16 adapted to the clamping finger 11. The pin is sent into the pinhole 15 by the vibration of the pin vibration disk 14, and then the pin is fixed by the clamping of the clamping finger 11 to prevent the pin from falling during the rotation of the rotary pin transmission mechanism 1. Note: Before the pin vibration disk 14 sends the pin into the pinhole 15, the opening mechanism 13 must first open the clamping finger 11 to facilitate the smooth entry of the pin. When the pin is in place, the opening mechanism 13 releases the clamping finger 11, and the front end of the clamping finger 11 is clamped on the pin under the action of the elastic member 12.

[0018] The texturing mechanism 2 is arranged above the rotary pin transmission mechanism 1, and includes a set of longitudinally arranged guide posts 17, a template 18 slidably arranged on the guide posts 17, a clamping plate 19 hinged on both sides of the template 18, a push rod 20 hinged on the top of the clamping plate 19, a mounting seat 21 hinged on the bottom of the clamping plate 19, and a guide rod 22 horizontally arranged between the mounting seats 21. A texturing cylinder 24 is connected between the tops of the push rods 20 through a linkage plate 23. A texturing module 25 is provided at the front end of the mounting seat 21, and matching texturing grooves 61 are provided between the texturing modules 25. The clamping plate 19 is usually hinged at the lower end with the template 18 to form a labor-saving lever, so that texturing can be performed more labor-savingly. After adopting the above structure, when the texturing cylinder 24 presses down the linkage plate 23, the various components are linked to move the texturing module 25 downward and texturing the insertion pin; when the texturing cylinder 24 pulls up the linkage plate 23, the texturing module 25 is opened and away from the insertion pin.

[0019] The plastic shell conveying and pre-pressing mechanism 3 includes a main plastic shell conveying channel 26 arranged horizontally, and a plastic shell handling mechanism 27 arranged above the main plastic shell conveying channel 26. The main plastic shell conveying channel 26 is provided with a movable plastic shell conveying channel 28 for pre-pressing at the position corresponding to the rotary pin conveying mechanism 1, and one side of the movable plastic shell conveying channel 28 is provided with a pre-pressing cylinder 29 for moving it toward the rotary pin conveying mechanism 1. When the rotary pin conveying mechanism 1 rotates the bitten pin to the side of the plastic shell conveying and pre-pressing mechanism 3, the movable plastic shell conveying channel 28 is pushed forward by the pre-pressing cylinder 29, so that the plastic shell in the movable plastic shell conveying channel 28 is pre-pressed with the pin. Note: The rear end (inner cavity end) of the plastic shell faces the pin.

[0020] The pin crimping mechanism 4 includes a crimping plate 30 and a crimping cylinder 31 that drives the crimping plate 30 to move toward the shell conveying and pre-pressing mechanism 3. The number of the crimping plates 30 is the same as the number of the clamping fingers 11. When the pre-crimped connector is conveyed to the front of the crimping plate 30 by the shell conveying and pre-pressing mechanism 3, the crimping cylinder 31 moves the crimping plate 30 forward and clamps the widened portion of the pin into the shell.

[0021] During assembly: first, the pin is transferred to the pin hole 15 of the fixing seat 10 through the pin vibration plate 14, and at the same time, the plastic shell is transferred to the movable plastic shell transfer channel 28 through the plastic shell conveying mechanism 27, and then the pin is rotated to the biting mechanism 2 for biting through the rotary pin conveying mechanism 1, and then the bitten pin is rotated to the plastic shell conveying and pre-pressing mechanism 3 for pre-crimping through the rotary pin conveying mechanism 1, and after pre-crimping, it is transferred to the pin crimping mechanism 4 for crimping through the plastic shell conveying mechanism 27, and this cycle is repeated until the processing is completed.

Since the inclined sorting surfaces 37 are provided on both sides of the sorting grooves 36 of the pin sorting plate 34, when the pins are transmitted through the vibration disk body 32, they can more easily enter the sorting grooves 36, and then the pins in the sorting grooves 36 are transmitted to the needle grooves 35 on the surface of the pin transmission channel 33 through vibration to prevent needle leakage. It is more ideal that the sorting grooves 36 are slightly larger (greater than 0.5-1mm) than the needle grooves 35.

When the rotating shaft 7 rotates an angle (90°), the positioning cylinder 4 pushes up the first positioning plate 39 so that the positioning groove 40 is inserted into the square positioning block 38, so as to accurately position and position the rotating shaft 7, so that biting and crimping can be performed more accurately and stably.

[0024] Preferably, the opening mechanism 13 includes a gate plate 42 and a gate plate cylinder 43 for driving the gate plate 42 to rise and fall, and the clamping finger 11 is provided with a pressing portion 44 that cooperates with the gate plate 42. Or the opening mechanism 13 includes a slide plate 51 that is tilted, a rolling shaft 52 and a second positioning plate 53 provided on the slide plate 51, and a slide plate cylinder 54 that drives the slide plate 51 to move. When the clamping finger 11 is to be opened, the gate plate 42 or the rolling shaft 52 is driven by the cylinder to apply pressure to the pressing portion 44 of the clamping finger 11. In the above-mentioned second opening mechanism 13 with the second positioning plate 53, when the rolling shaft 52 applies pressure to the pressing portion 44 of the clamping finger 11, the second positioning plate 53 is positioned on the surface of the pin, so that the pin can enter the pinhole 15 more smoothly.

[0025] Preferably, the plastic shell conveying mechanism 27 includes a slide rail 45, a group of sliders 46 arranged at intervals on the slide rail 45, and a first conveying cylinder 47 for driving the sliders 46 to move synchronously. The sliders 46 are provided with an L-shaped baffle 48 extending into the main plastic shell conveying channel 26, and a second conveying cylinder 49 is provided on the upper end of the L-shaped baffle 48. The first conveying cylinder 47 controls the left and right synchronous sliding of a group of sliders 46, and the second conveying cylinder 49 controls the up and down movement of the L-shaped baffle 48. When the plastic shell on the main plastic shell conveying channel 26 is conveyed, the L-shaped baffle 48 is inserted into both sides of the plastic shell through the cooperation of the second conveying cylinder 49 and the L-shaped baffle 48 to extract a fixed number (5 in this example) of plastic shells and convey them to the next process, so as to achieve stable conveyance of the plastic shells.
