A conveying part for conveying the pins 100 is horizontally arranged above the notch of the placing groove a1, and comprises a conveying belt and two chain wheels a6, and a bearing plate a7, wherein the conveying belt comprises a belt body a2 and a pair of parallel and spaced chains a5, and the belt body a2 is connected between the two chains a5 to move synchronously with the two chains. Chain a5 with sprocket a6 corresponds the meshing transmission still be connected with into positioning piece a3 of pin 100 on the area body a2 type gesture, positioning piece a3 is the channel-section steel structure of vertical setting and its opening side sets up towards the input direction of pin 100, the bottom of the pi type inner chamber of positioning piece a3 with the one end of a rectangular strip hole a4 on the area body a2 aligns, UNICOM. The length direction of the rectangular strip hole a4 is the same as the length direction of the tape body a2, and the other end of the rectangular strip hole a4 faces the input side of the pin 100, and the length and width of the rectangular strip hole a4 need to make the pin 100 directly leak from the rectangular strip hole a4 when being placed in a master L-shaped posture. Meanwhile, the loading plate a7 is horizontally arranged below the belt body a2, and the rectangular bar hole a4 at the position outside the position where the belt body a2 moves to the placement groove a1 is completely closed, so that the pin 100 can be smoothly transported and prevented from leaking from the rectangular bar hole a 4. In use, the vertical section of the pin 100 in the L-shaped position is vertically inserted into the n-shaped inner cavity, so that the pin 100 which is positioned in the rectangular bar hole a4 and is limited by the positioning piece a3 in the position can leak into the accommodating groove a1 when being transported to the position above the accommodating groove a 1.

In use, the belt body a2 is firstly positioned above the positioning groove a1, when the pins 100 are placed in the master position a3 and in the master position l, the pins 100 in the rectangular holes a4 are supported by the carrier plate a7 and move toward the side of the positioning groove a1 along the conveying direction of the belt, when the pins move to a certain position above the notch of the positioning groove a1, the corner portions of the pins 100 begin to leak downward and enter the notch of the positioning groove a1, and as the belt continues to convey forward, the vertical portion of the pins 100 in the master position l and the corner portions land first, fall into the bottom of the corner portions a1 and finally lean into the positioning groove a1, and the top ends of the pins 100 are exposed out of the notch of the positioning groove a1, therefore, the length of the rectangular holes a4 is preferably designed to be as long as possible to allow the belt to move upward, leaving room for subsequent pass-through mounting between pin 100 and insulator 200 in preparation for the lead.

Based on the above structural design, in order to further optimize and perfect the assembly of the electrical connector, the automatic assembly equipment for production and processing of electrical connectors of the present invention further includes a first fitting part for penetratingly mounting the pin 100 on the insulator 200, and a second fitting part for mounting the upper insulating cap 300 on the top end of the pin 100.

Specifically, as shown in fig. 5 to 8, the first mounting member includes a base b1 having an ┙ -shaped step formed on one side thereof, and a flat rectangular cavity b34 is formed in a recessed manner in a step vertical side wall b3, wherein the rectangular cavity b34 has a length direction in a left-right direction and a height direction in a vertical direction and upwardly penetrates through the top surface of the base b1 in the height direction, so that the top surface of the rectangular cavity b34 and a surface facing the step edge are both open. The base b1 is provided with a slide plate b2 horizontally sliding on the step surface of the step vertical side wall b3, and the upper surface of the slide plate b2 participates in forming the inner bottom surface of the rectangular cavity b 34. The outer stop b4 is arranged opposite to and upright from the step vertical side wall b3, the side face of the outer stop b4 departing from the step vertical side wall b3 comprises an upper arc surface and a lower vertical plane, the outer stop b4 can horizontally slide on the step surface, one side of the outer stop b4 departing from the step vertical side wall b3 is connected with a vertically arranged bracket b6 through a first spring b5, the bottom end of the bracket b6 is fixed at the edge of the step surface, a vertically arranged blind hole is formed in the top end of the bracket b6, a vertically arranged second spring b7 is installed in the blind hole, the top end of the second spring b7 extends out of the blind hole to be connected with a movable frame b8 only capable of vertically moving, and the second spring b7 plays a supporting role in supporting the movable frame b 8. The inside blind chamber that has of adjustable shelf b8, blind chamber top end opening just towards the lateral wall of outer dog b4 has a U-shaped opening b10, and vertical installation has third spring b9 in the blind chamber, and under free state, the top of third spring b9 is higher than opening b 10's bottom and be connected with the horizontal segment of gamma type punching press pole b 11. The horizontal section can horizontally move left and right, a squeezing rod is vertically fixed on one side of the movable frame b8 facing the outer stop b4, and a roller b12 is installed at the bottom end of the squeezing rod. The bottom end of the vertical section of the punching rod b11 is provided with a punching block, the punching block comprises a main block b13 and a sub-block b32, the main block b13 and the sub-block b32 are elastically and telescopically connected in the horizontal direction and are always on the same horizontal line, for example, a sliding connecting shaft b33 is adopted for connection, and a cylindrical spring is sleeved on the sliding connecting shaft b33 to realize elastic extension. Preferably, the length of the stamping block in the non-working state is 1.2-1.5 times of the horizontal width of the stamping cavity.

Meanwhile, a pressing handle b18 for connecting with a main shaft of the press is fixedly connected to the horizontal section of the punching rod b11, for example, when a left placing groove a1 and a right placing groove a are arranged, two pressing handles b18 are respectively connected with a horizontally arranged telescopic shaft, the telescopic shafts are connected with a T-shaped block at the same time at the ends close to each other, and the top ends of the T-shaped blocks are used for contacting and transmitting force with the main shaft of the press. When the pressing handle b18 is pressed downwards, the punching rod b11 slides downwards vertically under the guiding action of the notch b10, and in the process: the roller b12 firstly contacts with the arc surface of the outer baffle to gradually push the outer block b4 to one side of the step vertical side wall b3, when the movable frame b8 contacts with the top end of the bracket b6, the outer block b4 is pushed to the position where the rectangular cavity b34 is sealed towards the opening of one side of the step edge, and at the moment, the outer block b4 and the rectangular cavity b34 enclose a rectangular placement groove a1 with only the top open; when the punching block is pressed down to the limit position, the pin 100 stands in an L shape and rests on the vertical side wall of the rectangular cavity b 34.

When the stamping device is used, the stamping rod b11 gradually moves downwards, the horizontal section of the stamping rod compresses the second spring b7 and the third spring b9, when the roller is firstly contacted with the arc surface at the upper part of the side surface of the outer stop b4, the stamping block is not contacted with the outer stop b4, continuously, when the roller moves downwards to the limit, namely the movable frame b8 is contacted with the top end of the bracket b6, the outer stop b4 and the rectangular cavity b34 form a rectangular placement groove a1 only with an open top, and at the moment, the stamping block is about to enter the placement groove a1 or enter the placement groove a 1. As the punch lever b11 is further pressed downward, the third spring b9 continues to be compressed and the punch block continues to be pressed downward, so that finally when the punch block is pressed downward to the limit position, the pin 100 stands in an L-shape, rests on the vertical side wall of the rectangular cavity b34, and the pin 100 is limited to the preset position. With multiple pins 100, all pins 100 can be quickly moved down by the insulator 200 to make a socket-type through-mount connection. Certainly, the insulator 200 can be directly moved to the position above the placing groove a1 to move downwards after being grabbed by a grabbing device such as an existing manipulator, and the like, and covers the pins 100 in a pressing manner, so that the insulator 200 can be rapidly inserted and assembled in a penetrating manner at one time when a plurality of pins 100 are formed, and a semi-finished product is formed. When the semi-finished product needs to be taken out, after the pressure on the stamping rod b11 is released, under the elastic force of the second spring b7 and the third spring b9, the stamping rod b11 automatically moves upwards, and after the stamping rod b11 moves upwards to a certain height, the second spring b7 jacks up the movable frame b8 greatly, so that the roller b12 moves upwards to a position separated from the outer stop b4 or contacted with the arc surface, the outer stop can be automatically pulled back to the original position under the action of the first spring b5, namely, the outer stop moves close to one side of the fixed frame, so that the stamping block can have a space moving towards one side of the fixed frame, namely, the stamping rod b11 can retreat in the horizontal direction, the stamping block is conveniently and completely staggered in the horizontal direction with the assembled insulator 200, and the stamping block is allowed to separate from the mounting groove a1 after moving upwards, so that the semi-finished product formed by the assembled pin 100 and the insulator 200 can be taken out smoothly. On the other hand, when the punch presses the pin 100 to correct the posture of the pin 100, the block b32 of the punch presses down and simultaneously applies a horizontal pushing force to the pin 100 toward the vertical side wall of the installation groove a1, so that the pin 100 is pushed to a predetermined position standing upright in an L shape and leaning on the vertical side wall of the rectangular cavity b34, and the slide plate b2 is provided to perfectly assist the correction.

Preferably, in a specific implementation, the bottom end of the sliding plate b2 is provided with a plurality of rollers b30 to support the sliding of the sliding plate b 2. And both ends of the sliding plate b2 are respectively connected with a fourth spring b31 to facilitate the resetting of the sliding plate b 2.

In addition, an adjusting screw is vertically installed in the base b1, one end of the adjusting screw, which penetrates through the top surface of the base b1, is rotatably connected with an adjusting block b19, and the side surface of the adjusting block b19, which faces one side of the rectangular cavity b34, participates in enclosing the rectangular cavity b34, so that the arrangement of the pin 100 with a wider range of lengths can be realized, and the adaptability is stronger.

In addition, to realize the vertical movement of the movable frame b8, there are many methods, and the recommended structure of the embodiment is as follows: the movable frame b8 slides vertically under the guidance of the guide rod b36, the top end of the guide rod b36 passes through the movable frame b8 in a sliding fit manner and extends out of the springboard b38 outside the top end face of the bracket b6, and the bottom end of the guide rod b36 is fixedly connected with the side wall of the bracket b 6. The structure is simple and compact, the integrity is good, and in order to continue the lifting effect, an auxiliary plate b37 is further horizontally and fixedly connected to the side wall of the movable frame b8, and the top end of the guide rod b36 penetrates through the auxiliary plate b37 in a sliding fit mode, so that the movement is more stable and reliable.

In order to avoid the damage to the base b1 caused by the contact of the pressing rod with the base b1, and simultaneously, to ensure that the roller b12 is more stable when being close to the middle of the stop block as much as possible to form the placing groove a1, when the placing groove a1 is formed, the roller b12 is not in contact with the base b1, and the roller b12 is tangent to the vertical plane of the lower part of the outer stop block b 4.

For the above-mentioned implementation structure of the first assembling part, in order to adjust the height of the insulator 200 sleeved on the pin 100 at some time, as shown in fig. 5, 6 and 9, a lead screw b15 may be added, the lead screw b15 is vertically and rotatably installed in the vertical section of the stamping rod b11, and a screw block b14 is screwed on the lead screw b15, and one end of the screw block b14 extends out of the vertical strip hole on the vertical section and can be contacted with one side of the insulator 200 moving downwards. By designing in this way, after the stamping block shapes the posture of the pin 100, the screw rod b15 is rotated, so that the screw block b14 moves to a preset height to block the insulator 200 from moving downwards, thereby controlling the downward moving height of the insulator 200 and controlling the installation position height of the insulator 200 on the pin 100. Furthermore, in order to facilitate accurate control and adjustment of the height value, an annular code wheel b16 is fixedly connected above a horizontal segment of the stamping rod b11, the upper surface of the code wheel b16 has a numerical value indicating the height position, the top end of the screw rod b15 penetrates through the center of the code wheel b16 and is fixedly connected with a hand wheel b17, the top end of the screw rod b15 close to the code wheel b16 is also connected with a pointer b35 along the radial direction, and the pointer b35 points to the numerical value.

Finally, in the present embodiment, with reference to fig. 10 to 12, the second fitting part is structured as follows: the device comprises a workbench c4 for placing the pins 100 in an L-shaped placing posture, a sensor c8 is mounted on the workbench c4, and a press mounting plate c7 capable of being pressed downwards is arranged right above the placing position of the pins 100 on the workbench c 4. An automatic transmission system is arranged above the workbench c4 and comprises wire wheels and a conveying rope, wherein the wire wheels comprise 4 outer wire wheels c1 and 4 inner wire wheels c2, the 4 outer wire wheels c1 and the 4 inner wire wheels c2 form a rectangular arrangement respectively, and each 4 wire wheels are positioned at the four corners of the corresponding rectangle. The conveying rope is equipped with two and the cross section is the rectangle, and every conveying rope winds on 4 lines that correspond to form a rectangular wire frame that is the tensioning state, and the outer rectangular wire frame of tensioning is located the outside of the interior rectangular wire frame of tensioning on the interior line wheel c2 on the outer line wheel c1, two sidelines c3 that outer rectangular wire frame and interior rectangular wire frame just to one another pass the two strip caulking grooves of insulator cap 300 respectively. The insulating cap 300 is correspondingly attached to the right angle of the groove bottom at the edge of the strip-shaped caulking groove, and the two side lines c3 are always away from each other, so that the insulating cap 300 is firmly erected on the two side lines c 3; when the sensor c8 detects that the insulation cap 300 is conveyed to the position right above the pin 100 by the two side lines c3, the press disc c7 is pressed downwards to mount the insulation cap 300 on the top end of the pin 100.

In a specific manufacturing process, the workbench c4 can be used for placing the insulator 200 and the pin 100 which are already through-plugged together, and the structure of the workbench can be designed by referring to the placing groove a1 of the first assembling part, or the first assembling part is directly used for pre-installing the connected pin 100 and the insulator 200, namely, the workbench c4 is the first assembling part. In use, after the insulator 200 is installed, the pins 100 are pre-positioned using the pressing and positioning action of the punch. On the other hand, by means of the special structure of the two strip-shaped caulking grooves of the insulation cap 300, under the tightening action of the two side lines c3, erection and conveying are carried out, specifically, the open ends of the strip-shaped caulking grooves of the insulation cap 300 are downward and are pressed down after being directly aligned along the length direction of the two side lines c3, and as the lower part of the outer side of the inner side wall of each strip-shaped caulking groove is provided with an arc-shaped protruding part protruding inwards, when the side lines c3 penetrate, the bottoms of the strip-shaped caulking grooves are provided with accommodating spaces, and when the insulation caps 300 are pressed and assembled one by one, the insulation caps can be directly connected in series on one side line c3 (conveying rope). At this moment, the conveying rope can be taken down or cut short, so that the collection and arrangement of the connectors can be realized, the batch information can be conveniently recorded, and the device is very useful. As for the shape of the rectangular wire frame, the press mounting of the insulating caps 300 of a plurality of models (different strip caulking groove pitches) can be realized by changing the pitches of side lines c3 on a plurality of sides on one production line, and the specification production is diversified and flexible. In addition, for the erection and fixation of the pair of side lines c3 to the insulating cap 300, the side wall at the notch of the strip-shaped caulking groove is thinnest, so that the distance between the two corresponding side lines c3 is large, and the bottom of the strip-shaped caulking groove is thicker, so that the distance between the two corresponding side lines c3 is smaller, which is determined that the insulating cap 300 can be stably buckled on the pair of side lines c3, and the method is quite ingenious and applicable. From the above, the structural mode of the automatic transmission insulating cap 300 makes full use of the structural characteristics of the insulating cap 300, and the insulating cap is perfectly matched with the insulating cap for production.

In order to automatically detect the position, the sensor c8 is installed at a position where the upper surface of the worktable c4 is placed next to the insulator 200, and detects whether the insulation cap 300 is in place for timely press-fitting. Meanwhile, a wire tightening device capable of adjusting the distance between the two side lines c3 is further arranged between the two side lines c3, the tension erection stability of the insulation cap 300 is adjusted, and the insulation cap 300 is suitable for insulation caps 300 with more specifications. As shown in fig. 10 and 13, the specific structure is as follows: the stringing device comprises a cantilever c5 and a pressing wheel c6, one end of the cantilever c5 is fixedly arranged, the pressing wheel c6 is installed at the other end of the cantilever c5, and the pressing wheel c6 can be pressed on the sideline c3 close to the line wheel. Based on this, more specifically, the cantilever c5 is rotatably mounted on a mounting plate fixedly arranged above the reel mandrel, and the cantilever c5 can be fixed on the mounting plate after rotating to any angle. Or one end of the cantilever c5 is fixedly installed on an installation disc fixedly arranged above the reel mandrel, and the cantilever c5 is a telescopic rod structure with variable length. When the device is used, the pressing wheel c6 is pressed and a certain sideline c3 is loosened, and the distance between the two sidelines c3 is changed. The cross section of the wheel groove on the pressing wheel c6 for the side line c3 to pass through is rectangular and is matched with the shape of the conveying rope. In addition, it is effective that the transfer string is an elastic string, and the insulation cap 300 is more easily and stably mounted by using the elastic force.

In all the embodiments, the pins 100 are automatically fed, the pins 100 are inserted into the insulator 200 in a penetrating manner, the insulating cap 300 covers the top ends of the pins 100, and three process links are specifically described, which are objectivity evidences of continuous process effects and describe how to assemble, package and mold the electric connector in detail.
