Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to an automatic wire plug assembly machine for processing plugs. Background Art

[0002] A plug, also called a plug pin, is a connector attached to one end of a wire that plugs into an outlet to connect the power source. It primarily consists of a power lead, an insulated housing, and metal prongs. A three-prong plug requires grounding and has three metal prongs, while a two-prong plug does not require grounding and has two metal prongs.

[0003] In the prior art, plug assembly usually involves either workers manually assembling the wires, housing, and pins together, which is inefficient and labor-intensive. The product quality of the plug cannot be guaranteed and is prone to deviations. Alternatively, the plug assembly is divided into different processing steps, and the wires, housing, and pins are manually transferred between different processing devices to form a semi-automated assembly line process. However, this assembly method results in poor continuity between the various processing steps, which can easily cause the relative positions of the wires, housing, and pins to shift, failing to meet the precision requirements of plug assembly, ultimately affecting the quality of the plug. In severe cases, it may cause electrical fires during subsequent use, posing a serious threat to the personal and property safety of consumers. Summary of the Invention

Detailed implementation manners

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] On the contrary, the present invention covers any alternatives, modifications, equivalent methods and solutions made within the spirit and scope of the present invention defined by the claims. Further, in order to enable the public to have a better understanding of the present invention, in the following detailed description of the present invention, some specific details are described in detail. Those skilled in the art can fully understand the present invention without the description of these details.

[0048] As Figure 1 , Figure 2 and Figure 13 shown, the automatic wire plug assembling machine includes a workbench 1. A turntable 2 and a first driving mechanism for driving the turntable 2 to rotate are arranged on the workbench 1. A clamping mechanism 3 for clamping a wire is arranged along the circumferential direction of the outer edge of the turntable 2. The clamping mechanism 3 includes an upper clamp 20 and a lower clamp 21 which are oppositely arranged. A gap for placing the wire is arranged between the upper clamp 20 and the lower clamp 21. The clamping mechanism 3 further includes a connecting member 22 arranged between the upper clamp 20 and the lower clamp 21. The connecting member 22 is arranged in an inverted "L" shape. A through hole 1 is axially formed in the upper clamp 20. The longitudinal end of the connecting member 22 is inserted into the through hole 1 and the end of the longitudinal end is connected to the lower clamp 21. An elastic member 23 is arranged between the end of the transverse end of the connecting member 22 and the upper clamp 20. In this embodiment, the elastic member 23 is arranged as a compression spring. When a downward pressure is applied to the transverse end of the connecting member 22, the longitudinal end of the connecting member 22 slides downward in the through hole 1, that is, slides downward in the direction of the lower clamp 21, driving the lower clamp 21 to move downward, so as to open the gap between the upper clamp 20 and the lower clamp 21, enabling the wire to be placed. At this time, the elastic member 23 contracts and deforms due to the external load. When the force applied to the transverse end of the connecting member 22 disappears, due to the elastic force of the elastic member 23, the connecting member 22 can be reset, thereby driving the lower clamp 21 to move upward, and the upper clamp 20 and the lower clamp 21 cooperate to clamp the wire.

[0049] As Figure 1 , Figure 3 and Figure 15As shown in the figure, along the conveying direction of the turntable 2 on the workbench 1, a wire loading station, a wire sleeve loading station, a wire stripping station, a pin installation station, a wire sleeve heat shrink forming station, a housing installation station, and a plug unloading station are sequentially arranged. A wire feeding device 4 and a wire cutting device are arranged at the wire loading station. A wire sleeve feeding device 5, a wire sleeve cutting device, and a first wire sleeve displacement device 6 are arranged at the wire sleeve loading station. A wire cutting device 7 and a wire stripping device 8 are arranged at the wire stripping station. A pin and wire fixing device 9 is arranged at the pin installation station. A second wire sleeve displacement device 10 and a wire sleeve heating device 11 are arranged at the wire sleeve heat shrink forming station. A housing and pin fixing device 12 is arranged at the housing installation station. A conveying device 13 is arranged at the plug unloading station. A reasonable spatial layout is adopted on the workbench 1. Through the rotation of the turntable 2, wires, wire sleeves, pins, and housings are conveyed to each processing station for processing and installation, enabling continuous assembly production of plugs, saving production time, and improving production efficiency.

[0050] As Figure 1 , Figure 2 , Figure 17 and Figure 18 shown, since wire loading needs to be achieved at the wire loading station and pin unloading, i.e., wire unloading, needs to be achieved at the housing installation station, control devices 29 for controlling the opening and closing of the upper fixture 20 and the lower fixture 21 are arranged at both the wire loading station and the housing installation station. To prevent the plug from not being unloaded at the plug unloading station after the plug assembly is completed and being conveyed back to the wire loading station again through the rotation of the turntable 2, a control device 29 for controlling the opening and closing of the upper fixture 20 and the lower fixture 21 is also arranged between the wire loading station and the plug unloading station. The control device 29 includes a pressing member 30 arranged above the connecting member 22 and opposite to the lateral end of the connecting member 22. A second driving mechanism for driving the pressing member 30 to move longitudinally towards the connecting member 22 is arranged on the workbench 1. The second driving mechanism applies a downward force to the connecting member 22, driving the lower fixture 21 to move downward, opening the gap between the upper fixture 20 and the lower fixture 21, so that the wire can be put in or taken out. An inductor six 19 is also arranged between the plug unloading station and the wire loading station. The inductor six 19 is arranged on the side of the pressing member 30 close to the wire loading station for detecting whether there is a plug on the clamping mechanism 3.

[0051] As Figure 1 , Figures 4 to 6As shown, the wire feeding device 4 includes a first fixed seat 31 arranged on the workbench 1 and a third driving mechanism for driving the first fixed seat 31 to move towards the clamping mechanism 3. A first tensioning wheel 33 for winding the wire is arranged on the first fixed seat 31 through a first connecting frame 32 to maintain the tension of the wire and facilitate the feeding of the wire. A first pressing roller assembly is arranged between the first tensioning wheel 33 and the clamping mechanism 3. The first pressing roller assembly includes an upper pressing roller 34 and a lower pressing roller 35 oppositely arranged on the first fixed seat 31. A fourth driving mechanism 36 for driving the lower pressing roller 35 to rotate is also arranged on the first fixed seat 31, and the fourth driving mechanism 36 is set as a servo motor. Two conveying pipes 37 for the wire to pass through are respectively arranged at both ends of the first pressing roller assembly to fix and convey the wire. The pressing member 30 at the wire loading station corresponds to the conveying pipe 37, so that it can be ensured that the clamping mechanism 3 rotated to face the conveying pipe 37 is opened by the control device, and the wire loading is accurately realized.

[0052] In this embodiment, an adjusting assembly is arranged on the first fixed seat 31 for adjusting the distance between the upper pressing roller 34 and the second lower pressing roller 48. The adjusting assembly includes an adjusting rod 109 rotatably arranged on the fixed seat in the horizontal direction and an adjusting rod 110 arranged on the first fixed seat 31 in the longitudinal direction. One end of the adjusting rod 109 is connected to the upper pressing roller 34, and the other end of the adjusting rod 109 is connected to the upper end of the adjusting rod 110 through an elastic member three 111. The lower end of the adjusting rod 110 is fixed on the first fixed seat 31. The elastic member three 111 can be set as a tension spring. The part where the adjusting rod 109 is rotatably connected to the first fixed seat 31 is the fulcrum. By using the lever principle and the elastic force of the elastic member three 111, the change in the horizontal height of the upper pressing roller 34 is realized, that is, the distance between the upper pressing roller 34 and the second lower pressing roller 48 is adjusted to adapt to the feeding of wires of different sizes and thicknesses.

[0053] As Figure 1 、 Figures 4 to 6As shown, the wire cutting device includes a first moving knife assembly disposed between the clamping mechanism 3 and the conveying pipe 37. The first moving knife assembly includes a first moving knife 38 and a second moving knife 39 corresponding to the wire respectively. In this embodiment, the first moving knife 38 and the second moving knife 39 are arranged opposite to each other vertically. At the end of the first moving knife 38 facing the wire, there are respectively cutting edges 1 corresponding to the two conveying pipes 37. At the end of the second moving knife 39 facing the wire, there are respectively cutting edges 2 corresponding to the cutting edges 1. Both the cutting edges 1 and the cutting edges 2 are set in a "V" shape. In this way, on the one hand, the positions of the two wires can be guaranteed, and on the other hand, the wires can be cut better to ensure the flatness of the wire cut. On the workbench 1, there is a fifth driving mechanism for driving the first moving knife 38 and the second moving knife 39 to move towards each other. The output ends of the fifth driving mechanism are respectively provided with a second connecting frame 40 connected to the first moving knife 38 and a third connecting frame 41 connected to the second moving knife 39. On one side of the first moving knife assembly, there is a second air blowing pipe 112. Below the first moving knife assembly, there is a second waste bin 113 for recycling wire waste, avoiding the accumulation of waste on the workbench 1 and affecting the processing.

[0054] As Figure 1 , Figure 2 and Figure 4 shown, through the transmission of the first pressing roller assembly, one end of the wire is conveyed into the clamping mechanism 3, and the first moving knife assembly cuts the other end of the wire. The turntable 2 rotates to drive the clamping mechanism 3 to rotate, thereby driving the wire to the wire sleeve feeding station for processing. To avoid accidents at the wire feeding station, the clamping mechanism 3 rotated to the wire sleeve feeding station does not carry the wire. Between the wire feeding station and the wire sleeve feeding station, there is a first inductor 14 for sensing whether the clamping mechanism 3 passing through the wire feeding station holds the wire.

[0055] As Figure 1 , Figure 4 , Figure 7 and Figure 8 shown, on the workbench 1, there is an installation frame 42. The wire sleeve feeding device 5 includes a wire sleeve storage device 43 and a second tensioning wheel 44 respectively disposed on the installation frame 42 to maintain the tension of the wire sleeve and facilitate the conveying of the wire sleeve. On the outer surface of the second tensioning wheel 44, there are respectively two first grooves 45 opened along its circumferential direction, and the distance between the two first grooves 45 is the same as the distance between the two conveying pipes 37. The wire sleeves are respectively wound on the first grooves 45, so that the distance between the two wire sleeves is the same as the distance between the two wires, and the positions of the two wire sleeves correspond to the positions of the two wires. In this way, it can be ensured that the wire sleeve can just be sleeved on the wire, improving the accuracy of processing.

[0056] As Figure 7 and Figure 8As shown, a second fixed seat 46 is provided between the tensioning pulley two 44 and the clamping mechanism 3, and a sixth driving mechanism for driving the second fixed seat 46 to move horizontally towards the clamping mechanism 3. A second pressing roller assembly is provided in the second fixed seat 46. The second pressing roller assembly includes an upper pressing roller two 47 and a lower pressing roller two 48 arranged oppositely. A seventh driving mechanism 49 for driving the lower pressing roller two 48 to rotate is also provided on the second fixed seat 46. The seventh driving mechanism 49 is set as a servo motor. Two pipes for the wire sleeves to pass through are respectively provided at both ends of the second pressing roller assembly, and the distance between the two pipes is the same as the distance between the two first grooves 45. Similarly, this is to make the distance between the two wire sleeves the same as the distance between the two wires, and the positions of the two wire sleeves correspond to the positions of the two wires. In this way, it can be ensured that the wire sleeves can just be sleeved on the wires, improving the accuracy of processing.

[0057] In this embodiment, an adjusting assembly two for adjusting the distance between the upper pressing roller two 47 and the lower pressing roller two 48 is provided on the second fixed seat 46. The adjusting assembly two includes an adjusting rod three 114 rotatably arranged horizontally on the second fixed seat 46 and an adjusting rod four 115 arranged longitudinally on the second fixed seat 46. One end of the adjusting rod three 114 is connected to the upper pressing roller two 47, and the other end of the adjusting rod three 114 is connected to the upper end of the adjusting rod four 115 through an elastic member four 116. The lower end of the adjusting rod four 115 is fixed to the second fixed seat 46. The elastic member four 116 can be set as a tension spring. The part where the adjusting rod three 114 is rotatably connected to the second fixed seat 46 is the fulcrum. By using the lever principle and the elastic force of the elastic member four 116, the horizontal height of the upper pressing roller two 47 changes, that is, the distance between the upper pressing roller two 47 and the lower pressing roller two 48 is adjusted to adapt to the conveying of wire sleeves of different sizes and thicknesses.

[0058] As Figure 7 and Figure 8 As shown, the wire sleeve cutting device includes a second moving knife assembly provided between the second fixed seat 46 and the clamping mechanism 3. The second moving knife assembly includes a first moving knife two 50 arranged below the wire sleeve. A driving mechanism eight for driving the first moving knife two 50 to move longitudinally towards the wire sleeve is provided on the workbench 1. When the driving mechanism eight drives the first moving knife two 50 to move longitudinally towards the wire sleeve, the side surface of the first moving knife two 50 facing the fixed seat is in close contact with the side surface of the fixed seat facing the first moving knife two 50. In this way, the wire sleeve can be better cut, ensuring the flatness of the cut of the wire sleeve.

[0059] As Figures 4 to 9As shown in the figure, a wire positioning mechanism 51 is provided between the first moving knife assembly and the clamping mechanism 3, and between the second moving knife assembly and the clamping mechanism 3. The wire positioning mechanism 51 includes a first positioning plate 52 and a second positioning plate 53 corresponding to the wire respectively. In this embodiment, the first positioning plate 52 and the second positioning plate 53 are arranged opposite to each other vertically. A notch 54 corresponding to the conveying pipe 37 or the pipeline is provided on one side of the first positioning plate 52 facing the wire, and a notch 55 corresponding to the notch 54 is provided on one side of the second positioning plate 53 facing the wire. A ninth driving mechanism for driving the first positioning plate 52 and the second positioning plate 53 to move towards each other is provided on the workbench 1. The notch 54 and the notch 55 correspond to form a through hole for the wire to pass through. The wire positioning mechanism 51 between the first moving knife assembly and the clamping mechanism 3 is used to determine the position of the wire in the clamping mechanism 3. The wire positioning mechanism 51 between the second moving knife assembly and the clamping mechanism 3 is used to fix the wire during the feeding process of the wire sleeve, further improving the accuracy between the wire sleeve and the wire, and preventing the wire sleeve from failing to be sleeved on the wire due to the shaking of the end of the wire.

[0060] A first limiting member 56 for controlling the distance between the first positioning plate 52 and the second positioning plate 53 is provided between the first positioning plate 52 and the second positioning plate 53. In this embodiment, the first limiting member 56 is arranged along the longitudinal direction. One end of the first limiting member 56 is fixed on the first positioning plate 52. When the ninth driving mechanism drives the first positioning plate 52 and the second positioning plate 53 to move towards each other and just clamp the wire, the other end of the first limiting member 56 contacts and abuts against the second positioning plate 53. At this time, the ninth driving mechanism stops driving, preventing the first positioning plate 52 and the second positioning plate 53 from exerting too much force and damaging the wire.

[0061] As Figure 1 、 Figures 4 to 6 shown in the figure, the number of the ninth driving mechanisms is set to two, which are respectively arranged on one side of the wire feeding device 4 and on one side of the wire sleeve feeding device 5. The output ends of the ninth driving mechanisms arranged on one side of the wire feeding device 4 are respectively provided with an upper wire bending rod 57 and a lower wire bending rod 58. The upper wire bending rod 57 and the lower wire bending rod 58 respectively correspond to the wire, and the distance between the upper wire bending rod 57 and the clamping mechanism 3 is less than the distance between the lower wire bending rod 58 and the clamping mechanism 3. When the ninth driving mechanism drives the upper wire bending rod 57 and the lower wire bending rod 58 to move towards each other, the horizontal height of the lower wire bending rod 58 is equal to or higher than the horizontal height of the upper wire bending rod 57. In this way, the wire can be bent to make the end of the wire far from the clamping mechanism 3 tilt upward, facilitating the subsequent feeding of the wire sleeve, effectively avoiding the dropping of the wire sleeve, and improving the production efficiency.

[0062] As Figure 1 、Figure 7 and Figure 8 As shown, since the end of the wire needs to be cut and stripped later, in order to avoid cutting the wire sleeve, it is necessary to first move the wire sleeve towards the clamping mechanism 3 to make it away from the end of the wire. Therefore, a first wire sleeve displacement device 6 is provided on one side of the wire sleeve feeding device 5. The first wire sleeve displacement device 6 includes a first clamping plate 59 and a second clamping plate 60 corresponding to the wire sleeve respectively, and a tenth driving mechanism for driving the first clamping plate 59 and the second clamping plate 60 to move towards each other. In this embodiment, the first clamping plate 59 and the second clamping plate 60 are arranged vertically opposite to each other. A third fixing seat 62 for fixing the tenth driving mechanism and an eleventh driving mechanism for driving the third fixing seat 62 to move horizontally towards the clamping mechanism 3 are provided on the workbench 1. The tenth driving mechanism drives the first clamping plate 59 and the second clamping plate 60 to clamp the wire sleeve, and the eleventh driving mechanism drives the third fixing seat 62 to drive the first clamping plate 59 and the second clamping plate 60 to move horizontally towards the clamping mechanism 3, that is, to drive the wire sleeve to move horizontally towards the clamping mechanism 3, so that the end of the wire is exposed, facilitating subsequent cutting. A second limiting member 61 for controlling the distance between the first clamping plate 59 and the second clamping plate 60 is provided between the first clamping plate 59 and the second clamping plate 60. In this embodiment, the second limiting member 61 is arranged in the longitudinal direction. One end of the second limiting member 61 is fixed to the first clamping plate 59. When the tenth driving mechanism drives the first clamping plate 59 and the second clamping plate 60 to move towards each other and just clamp the wire sleeve, the other end of the second limiting member 61 contacts and abuts against the second clamping plate 60. At this time, the tenth driving mechanism stops driving to prevent the first clamping plate 59 and the second clamping plate 60 from exerting too much force and clamping the wire, making it impossible to drive the wire sleeve to move.

[0063] As Figure 1 and Figure 3 shown, an inductor two 15 is provided between the wire sleeve loading station and the wire stripping station. After the wire sleeve is displaced, it moves to the inductor two 15 as the turntable 2 rotates to detect whether the wire sleeve is on the side of the wire towards the clamping mechanism 3.

[0064] As Figure 1 and Figure 11As shown, the tangent device 7 includes a third moving knife assembly. The third moving knife assembly includes a first third moving knife 63 and a second second moving knife 64 corresponding to the wire respectively. In this embodiment, the first third moving knife 63 and the second second moving knife 64 are arranged vertically opposite to each other. At the end of the first third moving knife 63 facing the wire, there are respectively cutting edges three on the same axis as the wire. At the end of the second second moving knife facing the wire, there are respectively cutting edges four corresponding to the cutting edges three. Both the cutting edges three and the cutting edges four are set in a "V" shape, which can make the cut surface flat. On the workbench 1, there is a twelfth driving mechanism for driving the first third moving knife 63 and the second second moving knife 64 to move towards each other. At the output ends of the twelfth driving mechanism, there are respectively a fourth connecting frame 65 connected to the first third moving knife 63 and a fifth connecting frame 66 connected to the second second moving knife 64.

[0065] A third limiting member 67 for controlling the distance between the first third moving knife 63 and the second second moving knife 64 is arranged between the fourth connecting frame 65 and the fifth connecting frame 66. In this embodiment, the third limiting member 67 is arranged along the longitudinal direction. One end of the third limiting member 67 is fixed to the fourth connecting frame 65. When the twelfth driving mechanism drives the first third moving knife 63 and the second second moving knife 64 to move towards each other and just cuts off the outer skin of the wire, the other end of the third limiting member 67 contacts and abuts against the fifth connecting frame 66. At this time, the twelfth driving mechanism stops driving, preventing the first third moving knife 63 and the second second moving knife 64 from exerting too much force and cutting off the whole wire.

[0066] As Figure 1 and Figure 10 As shown, the wire stripping device 8 includes a first second clamping plate 68 and a second second clamping plate 69 corresponding to the wire respectively, and a thirteenth driving mechanism for driving the first second clamping plate 68 and the second second clamping plate 69 to move towards each other. In this embodiment, the first second clamping plate 68 and the second second clamping plate 69 are arranged vertically opposite to each other. On the workbench 1, there is a fourth fixing seat 71 for fixing the thirteenth driving mechanism and a fourteenth driving mechanism for driving the fourth fixing seat 71 to move horizontally in the opposite direction of the clamping mechanism 3. The thirteenth driving mechanism drives the first second clamping plate 68 and the second second clamping plate 69 to clamp the outer skin after the wire is cut. The fourteenth driving mechanism drives the fourth fixing seat 71 to drive the first second clamping plate 68 and the second second clamping plate 69 to move horizontally in the opposite direction of the clamping mechanism 3, that is, to drive the outer skin after the wire is cut to move horizontally in the opposite direction of the clamping mechanism 3, and strip the outer skin at the end of the wire. A first waste bin 72 for recycling wire waste is arranged on the fourth fixing seat 71, avoiding the accumulation of waste on the workbench 1 and affecting the processing.

[0067] A limiting member four 70 for controlling the distance between the first clamping plate two 68 and the second clamping plate two 69 is arranged between the first clamping plate two 68 and the second clamping plate two 69. In this embodiment, the limiting member four 70 is arranged along the longitudinal direction. One end of the limiting member four 70 is fixed on the first clamping plate two 68. When the driving mechanism thirteen drives the first clamping plate two 68 and the second clamping plate two 69 to move towards each other and just clamp the outer skin after the wire is cut, the other end of the limiting member four 70 contacts and abuts against the second clamping plate two 69, preventing the first clamping plate two 68 and the second clamping plate two 69 from exerting too much force and damaging the wire.

[0068] As Figures 10 to 12 shown, a wire sleeve positioning mechanism 73 is arranged between the wire cutting device 7 and the wire stripping device 8. The wire sleeve positioning mechanism 73 includes a first positioning plate two 74 and a second positioning plate two 75 respectively corresponding to the wire sleeve. A driving mechanism fifteen for driving the first positioning plate two (74) and the second positioning plate two (75) to move towards each other is arranged on the workbench (1). In this embodiment, the first positioning plate two 74 and the second positioning plate two 75 are arranged opposite to each other up and down. The two ends of the first positioning plate two 74 are respectively arranged as a first chuck one 76 and a first chuck two 77, and the two ends of the second positioning plate two 75 are respectively arranged as a second chuck one 78 and a second chuck two 79. The first chuck one 76 and the second chuck one 78 are arranged opposite to each other and are arranged between the wire cutting device 7 and the clamping mechanism 3 to clamp the wire sleeve located between the wire cutting device 7 and the clamping mechanism 3. The first chuck two 77 and the second chuck two 79 are arranged opposite to each other and are arranged between the wire stripping device 8 and the clamping mechanism 3 to clamp the wire sleeve located between the wire stripping device 8 and the clamping mechanism 3, which can avoid the wire sleeve shifting due to shaking during the wire cutting and wire stripping processes and interfering with the processing.

[0069] As Figure 1 and Figure 3 shown, to determine that the wire end stripping is completed and the wire is electrically conductive and can be used, a fixing base six 89 is arranged between the wire stripping device 8 and the pin and wire fixing device 9. A detector 90 for detecting whether the wire is electrically conductive is arranged on the fixing base six 89. Since the wire sleeve will move during the rotation of the turntable 2, a blowing pipe one 91 corresponding to the wire sleeve is also arranged on the fixing base six 89 to blow the wire sleeve towards the clamping mechanism 3 to avoid affecting the subsequent processing.

[0070] As Figure 1 、 Figure 3 and Figure 13As shown, the pin and wire fixing device 9 includes a pin feeding mechanism and a stamping mechanism. The pin feeding mechanism includes a vibrating disk one 80 for placing pins and a linear feeder one 81 arranged at the discharge port of the vibrating disk one 80. The sensor three 16 is arranged on the linear feeder one 81 corresponding to the pins. In this embodiment, the sensor three 16 is arranged at one end of the linear feeder one 81 facing the vibrating disk. When the sensor three 16 senses a pin, the vibrating disk stops feeding. When the sensor three 16 does not sense a pin, the vibrating disk continues to feed.

[0071] As Figure 13 and Figure 14 shown, in this embodiment, the stamping mechanism includes a stamping plate 82 arranged on the workbench 1 and connected to the linear feeder one 81. A die head 83 is arranged on one side of the stamping plate 82 facing the clamping mechanism 3. A groove two 84 corresponding to the end of the pin is opened on the upper end surface of the die head 83. A driving mechanism seventeen is arranged on the side of the stamping plate (82) away from the clamping mechanism (3). The output end of the driving mechanism seventeen is provided with a push rod 88 in contact with the pin. The linear feeder one 81 sequentially transports the pins to the stamping plate 82. The driving mechanism seventeen drives the push rod 88 to move horizontally towards the clamping mechanism 3, thereby pushing the pin to move horizontally towards the clamping mechanism 3, so that the end of the pin is located in the groove two 84 of the die head 83, and the wire is located above the end of the pin. A stamping head 85 and a driving mechanism sixteen for driving the stamping head 85 to move longitudinally towards the die head 83 are arranged above the die head 83. The driving mechanism sixteen is arranged on the workbench 1 through a fixing seat five 86. Through the stamping action of the stamping head 85, the pin is connected to the wire. As another solution, the stamping mechanism can also directly adopt a terminal machine to press the metal head at the end of the pin to the wire end and conduct electricity.

[0072] As Figure 1 、 Figure 13 and Figure 14As shown in the figure, since the wire is located above the pin, during the downward pressing process of the stamping head 85, the end of the wire will be pressed down into the end of the pin. Therefore, to make up for the height difference produced, fixing blocks 24 corresponding to the clamping mechanism 3 are sequentially arranged along the circumferential direction of the outer edge of the turntable 2. The fixing blocks 24 are slidably matched with the upper fixture 20 in the longitudinal direction. Through holes two 25 corresponding to the fixing blocks 24 are sequentially opened along the circumferential direction of the turntable 2, and the through holes two 25 are arranged along the axial direction of the turntable 2. Elastic members two 26 are inserted into the through holes two 25. In this embodiment, the elastic members two 26 are arranged as tension springs. One end of the elastic member two 26 is connected to the side of the fixing block 24 through a fastener one 27, and the other end of the elastic member two 26 is connected to the side of the lower fixture 21 through a fastener two 28. The output end of the driving mechanism sixteen is also provided with a vertical plate 87 corresponding to the upper fixture 20. The driving mechanism sixteen synchronously drives the stamping head 85 and the vertical plate 87 to move downward in the longitudinal direction. The vertical plate 87 drives the upper fixture 20 to slide downward on the fixing block 24, and the upper fixture 20 pushes the lower fixture 21 to also slide downward, so as to make the wire and the end of the pin at the same horizontal height to realize stamping and connection. After stamping, the driving mechanism sixteen synchronously drives the stamping head 85 and the vertical plate 87 to move upward in the longitudinal direction. The vertical plate 87 releases the upper fixture 20. Due to the elastic force of the elastic member two 26, the lower fixture 21 pushes the upper fixture 20 to reset.

[0073] As Figure 1 shown, an inductor four 17 is arranged between the pin installation station and the wire sleeve heat shrinkage forming station to detect that each wire has a pin, so as to avoid affecting subsequent processing.

[0074] As Figure 1 , Figure 15 and Figure 16 shown, after the wire and the pin are fixedly connected, the fixed connection between the wire sleeve and the pin also needs to be realized. First, the wire sleeve needs to be moved to the end of the wire facing the pin. The wire sleeve displacement device two 10 includes a first clamping plate three 92 and a second clamping plate three 93 corresponding to the wire sleeve respectively, and a driving mechanism eighteen for driving the first clamping plate three 92 and the second clamping plate three 93 to move towards each other. In this embodiment, the first clamping plate three 92 and the second clamping plate three 93 are arranged up and down relatively. A fixed seat seven 95 for fixing the driving mechanism eighteen and a driving mechanism nineteen for driving the fixed seat seven 95 to move horizontally in the opposite direction of the clamping mechanism 3 are arranged on the workbench 1. The driving mechanism eighteen drives the first clamping plate three 92 and the second clamping plate three 93 to clamp the wire sleeve, and the driving mechanism nineteen drives the fixed seat seven 95 to drive the first clamping plate three 92 and the second clamping plate three 93 to move horizontally in the opposite direction of the clamping mechanism 3, that is, to drive the wire sleeve to move in the opposite direction of the clamping mechanism 3, so that the wire sleeve contacts the pin.

[0075] A limiting member five 94 for controlling the distance between the first clamping plate three 92 and the second clamping plate three 93 is provided between the first clamping plate three 92 and the second clamping plate three 93. In this embodiment, the limiting member five 94 is arranged in the longitudinal direction. One end of the limiting member five 94 is fixed to the first clamping plate three 92. When the driving mechanism eighteen drives the first clamping plate three 92 and the second clamping plate three 93 to move towards each other and just clamp the wire sleeve, the other end of the limiting member five 94 contacts and abuts against the second clamping plate three 93. At this time, the driving mechanism eighteen stops driving, preventing the first clamping plate three 92 and the second clamping plate three 93 from exerting too much force and clamping the wire as well, making it impossible to drive the wire sleeve to move.

[0076] As Figure 1 , Figure 15 and Figure 16 shown, the wire sleeve heating device 11 includes an upper heating plate 96 and a lower heating plate 97 corresponding to the wire sleeve respectively. A hot air blower 98 connected to the upper heating plate 96 and the lower heating plate 97 respectively is arranged on the workbench 1. The wire sleeve is heat-shrunk and formed through the upper heating plate 96 and the lower heating plate 97 and fixedly connected to the pin.

[0077] As Figure 1 , Figure 17 and Figure 18 shown, the housing and pin fixing device 12 includes a housing feeding mechanism, a pin discharging mechanism and a pressing mechanism. The housing feeding mechanism includes a vibrating disk two 99 for placing the housing and a linear feeder two 100 arranged at the discharge port of the vibrating disk two 99. An inductor five 18 is arranged on the linear feeder two 100 corresponding to the housing. In this embodiment, the inductor five 18 is arranged at one end of the linear feeder two 100 facing the vibrating disk two 99. When the inductor five 18 senses the housing, the vibrating disk stops feeding. When the inductor five 18 does not sense the pin, the vibrating disk continues to feed. A base 101 connected to the linear feeder two 100 is arranged on the workbench 1. A groove three 102 for placing the housing is formed in the base 101 along the conveying direction of the housing. The linear feeder two 100 sequentially conveys the housing into the groove three 102.

[0078] The pin unloading mechanism includes a manipulator assembly disposed between the clamping mechanism 3 and the base 101 for clamping the pins. In this embodiment, the manipulator assembly includes a first manipulator 105 for removing the pins from the clamping mechanism 3 and a second manipulator 106 for placing the pins into the third groove 102. The first manipulator 105 is disposed on one side of the base 101, and the pressing member 30 at the housing installation station corresponds to the first manipulator 105. A twenty-first driving mechanism for driving the first manipulator 105 to perform a horizontal reciprocating motion between the clamping mechanism 3 and the second manipulator 106 is provided on the workbench 1. The second manipulator 106 is disposed on the other side of the base 101, and a twenty-second driving mechanism for driving the second manipulator 106 to move horizontally toward the base 101 is further provided on the workbench 1.

[0079] Since the clamping mechanism 3 is located above the base 101 and the first manipulator 105 is at the same height as the pins at the clamping mechanism 3, in order to make up for the height difference between the base 101 and the first manipulator 105, a twenty-third driving mechanism for driving the second manipulator 106 to rotate between the first manipulator 105 and the base 101 is further provided on the workbench 1. The twenty-third driving mechanism drives the second manipulator 106 to rotate 90°, driving the pins located above the base 101 to rotate 90°, so as to be inserted into the third groove 102 of the base 101 and realize the connection with the housing.

[0080] As Figure 1 、 Figure 17 and Figure 18 shown, the pressing mechanism includes a pressing rod 103 disposed above the base 101 along the longitudinal direction. A fixed seat eight 104 is provided on the workbench 1, and a twentieth driving mechanism for driving the pressing rod 103 to move longitudinally toward the base 101 is provided on the fixed seat eight 104. The pressing rod 103 is used to press the pins and the housing tightly to realize the fixed connection between the two and complete the assembly of one plug.

[0081] As Figure 1 、 Figure 17 and Figure 18As shown, after the plug assembly is completed, the plug needs to be unloaded and collected. The conveying device 13 includes a conveyor belt 107 disposed on one side of the base 101 away from the second linear feeder 100 and a twenty-fourth driving mechanism for driving the conveyor belt 107 to convey. The twenty-fourth driving mechanism is set as a servo motor. A clamp 108 for clamping the housing is disposed among the second linear feeder 100, the base 101, and the conveyor belt 107. A twenty-fifth driving mechanism for driving the clamp 108 to move horizontally towards the base 101 is disposed on the workbench 1. A twenty-sixth driving mechanism for driving the clamp 108 to move horizontally and linearly among the second linear feeder 100, the base 101, and the conveyor belt 107 is also disposed on the workbench 1. The clamp 108 clamps the housing on the second linear feeder 100 into the third groove 102, and then clamps the assembled plug in the third groove 102 onto the conveyor belt 107, realizing the unloading of the plug.

[0082] As Figures 1 to 3 shown, as Figure 1 , Figure 15 and Figure 16 shown, in this embodiment, a cam assembly is disposed below the workbench 1. The first driving mechanism, the second driving mechanism, the third driving mechanism, the fifth driving mechanism, the sixth driving mechanism, the eighth driving mechanism, the ninth driving mechanism, the tenth driving mechanism, the eleventh driving mechanism, the twelfth driving mechanism, the thirteenth driving mechanism, the fourteenth driving mechanism, the fifteenth driving mechanism, the sixteenth driving mechanism, the seventeenth driving mechanism, the eighteenth driving mechanism, the nineteenth driving mechanism, the twentieth driving mechanism, the twenty-first driving mechanism, the twenty-second driving mechanism, the twenty-third driving mechanism, the twenty-fifth driving mechanism, and the twenty-sixth driving mechanism are respectively connected to the cam assembly to realize driving and achieve a reasonable layout of the space. As another solution, a servo motor or a cylinder can also be used as the driving mechanism.

However, the present invention is not limited to the above embodiments.
