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 structures, such as Figure 15 As shown, the machine comprises a plastic housing 62 and a pin 63. The plastic housing 62 is provided with a pinhole for inserting the pin 63. To strengthen the connection between the pin and the housing, a texturing mechanism is typically used to texturize the pin 63, forming a widened portion 64. The structure of a conventional connector pin insertion machine, as shown in the Chinese invention patent application number "CN113067226B," entitled "Automated Connector Production Equipment," comprises a frame and a feeder mounted at the upper end of the frame. The feeder is provided within the feeder for conveying material. On one side of the frame, along the direction of material conveyance, are sequentially provided a feed mechanism for inputting the housing, a pin insertion mechanism for inserting the pin into the housing, a texturing mechanism, a shaping mechanism, a K-punching mechanism, a bending mechanism, a detection mechanism, and a discharge mechanism. The production process involves inserting the pin into the housing, then texturing the pin to increase its width. The pin is then reshaped so that the widened portion fits into the housing, strengthening the connection between the two. The pin is then punched outside the housing to bend the end into a specific shape. Finally, the pin outside the housing is bent 90 degrees to form the connector. The following disadvantages exist: 1. Because the pin is first inserted into the housing, then textured, and finally reshaped so that the widened portion fits into the housing, this process typically involves inserting the pin from the front end of the housing. This can cause the widened portion to damage the pinhole at the front end of the housing, resulting in poor waterproofing and pin stability. 2. The workstations are arranged side by side, making the equipment very bulky (long) and difficult to expand. 3. Pin leakage is common. Summary of the Invention

[0035] Reference Figures 1-14As shown, the fully automatic connector pin insertion machine of the present invention comprises: a rotary pin transport mechanism 1, a texturing mechanism 2, a molded shell transport and pre-pressing mechanism 3, and a pin crimping mechanism 4. The rotary pin transport mechanism 1 comprises a frame 5, a rotary pin fixture 6 mounted on the frame 5, and a pin vibrating plate 14 mounted 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 quartered pattern, and a driving mechanism 9 for rotating the rotating shaft 7 in the quartered pattern. The pin clamping mechanism 8 comprises a fixed base 10, a set of rotatable clamping fingers 11 mounted on the fixed base 10, an elastic member 12 that clamps the clamping fingers 11 toward the fixed base 10, and an opening mechanism 13 for opening the clamping fingers 11. The number of clamping fingers 11 varies depending on the needs. Typically, one clamping finger 11 completes the assembly of one connector. In this example, five clamping fingers 11 are used, meaning that five connectors can be assembled at once. The elastic member 12 is ideally a spring, but an elastic member such as a shrapnel may also be used instead. The front end of the fixing 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.

[0036] The texturing mechanism 2 is located above the rotary pin transport mechanism 1 and comprises a set of longitudinally arranged guide posts 17, a template 18 slidably mounted on the guide posts 17, clamping plates 19 hinged to either side of the template 18, a push rod 20 hinged to the top of the clamping plates 19, mounting blocks 21 hinged to the bottom of the clamping plates 19, and a guide rod 22 horizontally disposed between the mounting blocks 21. A texturing cylinder 24 is connected between the tops of the push rods 20 via a linkage plate 23. A texturing module 25 is provided at the front end of the mounting blocks 21, with mating texturing grooves 61 disposed between the modules. The clamping plates 19 are typically hinged at their lower ends to the template 18, forming a lever that reduces effort, enabling texturing. 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 texture the pins; when the texturing cylinder 24 pulls up the linkage plate 23, the texturing module 25 opens and moves away from the pins.

[0037] The molded case conveying and pre-pressing mechanism 3 comprises a horizontally arranged main molded case conveying channel 26 and a molded case handling mechanism 27 positioned above the main molded case conveying channel 26. A movable molded case conveying channel 28 for pre-pressing is located at the position of the main molded case conveying channel 26 corresponding to the rotary pin conveying mechanism 1. A pre-pressing cylinder 29 is connected to one side of the movable molded case conveying channel 28, which is used to move it toward the rotary pin conveying mechanism 1. When the rotary pin conveying mechanism 1 rotates the textured pins toward the molded case conveying and pre-pressing mechanism 3, the pre-pressing cylinder 29 pushes the movable molded case conveying channel 28 forward, completing the pre-pressing of the molded case and the pin within the movable molded case conveying channel 28. Note: The rear end (inner cavity end) of the molded case faces the pin.

[0038] The pin crimping mechanism 4 includes a crimping plate 30 and a crimping cylinder 31 that drives the crimping plate 30 toward the housing conveying and pre-pressing mechanism 3. The number of crimping plates 30 is the same as the number of clamping fingers 11. When the pre-pressed connector is delivered to the front of the crimping plate 30 by the housing conveying and pre-pressing mechanism 3, the crimping cylinder 31 moves the crimping plate 30 forward, snapping the widened portion of the pin into the housing.

[0039] During assembly: first, the pin is transferred to the pin hole 15 of the fixing seat 10 by the pin vibration disk 14, and at the same time, the plastic shell is transferred to the movable plastic shell transfer channel 28 by the plastic shell conveying mechanism 27, and then the pin is rotated to the texturing mechanism 2 by the rotary pin conveying mechanism 1 for texturing, and then the textured pin is rotated to the plastic shell conveying and pre-pressing mechanism 3 by the rotary pin conveying mechanism 1 for pre-pressing, and after pre-pressing, it is transferred to the pin crimping mechanism 4 by the plastic shell conveying mechanism 27 for crimping, and this cycle is repeated until the processing is completed.

[0040] Preferably, the pin vibrating disk 14 includes a vibrating disk body 32, a pin delivery channel 33 located at the discharge port of the vibrating disk body 32, and a pin sorting plate 34 located at the rear end of the pin delivery channel 33. The pin delivery channel 33 is provided with a set of spaced needle grooves 35 on its surface, and the pin sorting plate 34 is provided with a set of sorting grooves 36 connected to the needle grooves 35 on its surface. The sorting grooves 36 are flanked by inclined sorting surfaces 37. Because the sorting grooves 36 of the pin sorting plate 34 are flanked by inclined sorting surfaces 37, pins can more easily enter the sorting grooves 36 when they are delivered through the vibrating disk body 32. The pins in the sorting grooves 36 are then vibrated and transferred to the pin grooves 35 on the surface of the pin delivery channel 33, preventing needle leakage. Ideally, the sorting grooves 36 should be slightly larger (by 0.5-1 mm) than the pin grooves 35.

[0041] Preferably, a square positioning block 38 is provided at one end of the rotating shaft 7. A first positioning plate 39 is provided on one side of the square positioning block 38. The first positioning plate 39 is provided with a positioning groove 40. A positioning cylinder 41 is connected to the first positioning plate 39. When the rotating shaft 7 rotates a certain angle (90°), the positioning cylinder 4 pushes up the first positioning plate 39, inserting the positioning groove 40 into the square positioning block 38. This helps to accurately position and locate the rotating shaft 7, thereby enabling more precise and stable texturing and crimping.

[0042] Preferably, the opening mechanism 13 includes a gate plate 42 and a gate plate cylinder 43 that drives 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 cylinder drives the gate plate 42 or the pressing portion 44 of the clamping finger 11 of the rolling shaft 52 to apply pressure. 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.

[0043] Preferably, the molded case handling mechanism 27 includes a slide rail 45, a set of sliders 46 spaced apart on the slide rail 45, and a first handling cylinder 47 that drives the sliders 46 to move synchronously. The sliders 46 are equipped with L-shaped baffles 48 that extend into the main molded case conveying channel 26. A second handling cylinder 49 is located above the L-shaped baffles 48. The first handling cylinder 47 controls the synchronous left-right sliding of the sliders 46, while the second handling cylinder 49 controls the vertical movement of the L-shaped baffles 48. When a molded case is conveyed from the main molded case conveying channel 26, the second handling cylinder 49 cooperates with the L-shaped baffles 48 to insert the L-shaped baffles 48 onto either side of the case, extracting a fixed number of cases (in this example, five) and transferring them to the next process, thereby ensuring stable conveyance of the cases.

[0044] Preferably, a positioning column 50 is provided at the bottom of the template 18. It is used to position the template 18 after it is moved into place to achieve precise texturing.

[0045] Preferably, a cover plate 56 is provided on the surface of the pin delivery channel 33 via a quick-release device 55. An inclined pin guide surface 57 is provided at the front end of the cover plate 56. The cover plate 56 prevents the pins in the pin slot 35 from overlapping or falling out. The pin guide surface 57 is used to guide excess pins back into the vibration plate body 32.

[0046] Preferably, the driving mechanism 9 includes a sprocket 58 connected to the rotating shaft 7 and a stepping motor 59 that drives the sprocket 58 to rotate in equal steps.

[0047] Preferably, the front end of the clamping finger 11 is provided with a fixing groove 60 that can be embedded in the slot 16 for fixing the pin. After fixation, the pins are respectively embedded in the fixing groove 60 to achieve a more stable fixation.

[0048] As mentioned above, the present invention is not limited in any form.
