Description

Technical Field

[0001] The present invention belongs to the technical field of connector processing, specifically an integrated small pitch board-to-board connector and its processing technology. Background Art

[0002] The integrated small pitch board-to-board connector is a key electronic component used to connect two PCB boards, and realizes stable and efficient signal transmission between circuit boards through an electromechanical dual connection structure. It is widely used in electronic devices such as smart phones, computers, and smart homes, as well as automotive electronic modules such as in-vehicle navigation, entertainment systems, and driving assistance, undertaking the function of internal circuit board interconnection.

[0003] In the prior art during the production process of the integrated small pitch board-to-board connector, after the pin insertion device finishes the pin insertion work, the pin insertion device arranges and stores the connectors, and then the staff takes out the connectors one by one, places the connectors on the workbench of the bending machine, and squeezes the pins by the rotation of the bending block on the workbench, thereby completing the bending of the pins. After the bending work is completed, the staff then removes the connector, and then places the next connector for pin insertion and bending.

[0004] However, during the working process of the existing bending machine, after the pin insertion device finishes the pin insertion, the staff needs to take out the connectors one by one and transfer them to the bending station. After completing the clamping and positioning, the bending device is started. After the bending is completed, the staff then takes out the connectors. This process of loading and unloading a single connector requires repeated actions, resulting in low bending efficiency of the connectors. Moreover, each time the connector is placed on the bending machine, alignment and calibration are also required, increasing the bending time and causing the problem of low production efficiency.

[0005] Therefore, the present invention provides an integrated small pitch board-to-board connector and its processing technology. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: The integrated small pitch board-to-board connector and its processing technology of the present invention specifically include the following steps: Step 1, connector manufacturing: First, through die casting with a mold, a connector body is produced, and then it is cooled, demolded, and transported, and transported to a pin insertion machine for pin insertion work;

[0008] Step 2, pin insertion: The produced connector body is transported into the pin insertion machine through a transfer device, and then metal pins are inserted on one side of the connector. After the side-by-side insertion is completed, the connector is bent;

[0009] Step 3, Bending and Packaging: Place the connector after pin insertion in the clamping frame on the bending machine for fixation, then start the bending machine to bend the pins, thus completing the production of the integrated small pitch board-to-board connector. Then remove the bent connector and perform packaging to complete the production of the connector.

[0010] Preferably, the operation of the bending machine in Step 3 is as follows. First, a workbench is provided on the upper surface of the machine body. When performing the connection processing and bending process, the connector that has completed the pin insertion process is placed in the clamping frame on the upper surface of the workbench through the loading and unloading integrated component. After the connector is placed in the clamping frame, start the bending block on the upper surface of the bending machine body to perform the bending work on the pins of the connector.

[0011] Preferably, a jacking member is provided inside the workbench. When the bending work is completed, start the electric push rod. The electric push rod drives the fixed rod, and the fixed rod squeezes the air in the fixed cavity, making the internal air pressure increase. Then, it squeezes the top column to move upward along the vertical fixed cavity, and will drive the compression spring. The upward movement of the top column will jack up the top block, and the top block will then jack up the bent connector to complete the blanking and ejection of the connector.

[0012] Preferably, during the process of the top block jacking up the connector, the guide rail on the surface of the machine body starts, so that the sliding table in the guide rail drives the fixed frame to slide along the guide rail to the directly above the clamping frame, and the fixed frame abuts against the upper surface of the clamping frame. After the clamping frame moves to the directly above, it cooperates with the jacking member to perform the blanking work of the connector.

[0013] Preferably, after the fixed frame moves to the directly above the clamping frame, the top block of the jacking member will jack the bent connector into the fixed frame. When the connector enters the fixed frame, it will squeeze one group of clamping blocks in the fixed frame. The clamping blocks on both sides of the clamping block squeeze the spring and retract into the connecting groove, and then the connector will just be stuck between the two groups of clamping blocks, and then move to the directly below the auxiliary frame under the drive of the guide rail.

[0014] Preferably, after the fixed frame clamps the bent connector, start the guide rail to drive the sliding table, and then drive the fixed frame to slide along the guide rail to the directly below the auxiliary frame. During the process of the sliding table driving the fixed frame to move, the sliding table is rotationally connected with the gear. Therefore, the rotating columns on both sides of the fixed frame rotate along the rack plate with the gears at their ends. The rotation of the rotating columns will drive the fixed frame to turn over, so that it just turns over to the directly below the auxiliary frame, and the connector is also turned over, so that the pins of the bent connector will be vertically facing the ground.

[0015] Preferably, after the fixed frame is flipped to directly below the auxiliary frame, the second hydraulic cylinder is activated to push the insertion plate at its output end into contact with the partition plate. At this time, the partition plate will extend out of the auxiliary frame and gradually come into contact with the fixed frame. When the auxiliary frame is about to come into contact with the fixed frame, one of the third hydraulic cylinders on one side of the support frame is activated. The third hydraulic cylinder drives the positioning plate at its output end to disengage from the auxiliary frame, releasing the unbent connector at the bottommost end of the auxiliary frame. Then, the bottom end of the auxiliary frame is closed, and by misaligning the fixed frame and the auxiliary frame by a certain distance, the limiting frame at the end of the partition plate is driven to push the unbent connector and push it between the two sets of clamping blocks.

[0016] Preferably, during the process of the insertion plate limiting the feeding of the connector through the partition plate, when the second hydraulic cylinder resets after the limiting is completed, the partition plate automatically resets under the action of the connecting spring, so as to perform the next limiting work.

[0017] Preferably, during the process of the insertion plate driving the partition plate to push and press the connector in the misaligned fixed frame, one of the third hydraulic cylinders is activated to retract the insertion piece. Then, when the limiting frame pushes the connector into the fixed frame, the extrusion block on the top wall of the insertion plate will extrude the connector on the auxiliary top layer to descend, correcting the connector in the auxiliary cavity. Then, the third hydraulic cylinder pushes the insertion plate back in again, separating the lowermost connector from the upper-layer connector, preparing for the next feeding of the connector.

[0018] Integrated small pitch board-to-board connector.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. For the integrated small pitch board-to-board connector and processing technology described in the present invention, the connector is fixed by the clamping frame, and then through the integrated work of the loading and unloading assembly, the loading and unloading process of the connector is more convenient, and the automated loading and unloading reduces human errors and improves production efficiency.

[0021] 2. For the integrated small pitch board-to-board connector and processing technology described in the present invention, the electric push rod drives the fixed rod to compress the air in the fixed cavity, and uses the increased air pressure to push the top column to rise in the vertical direction. At the same time, the compression spring is stretched to store energy. When the top column moves up, the top block rises accordingly, pushing up the bent connector, realizing rapid blanking and top removal. This not only improves production efficiency, but also reduces manual operation and labor intensity. At the same time, the dual action of air pressure and spring ensures the smoothness and reliability of the top removal action. After the top removal is completed, the top block can automatically reset under the reset force of the compression spring, so as to be continuously used in a cycle, facilitating the next top removal.

[0022] 3. In the integrated small-pitch board-to-board connector and its processing technology of the present invention, during the process of the insertion board driving the partition plate to push and press the connector in the misalignment fixing frame, one of the third hydraulic cylinders is timely activated to retract the insertion piece. Because the extrusion block on the top wall of the insertion board will extrude the top-layer connector, causing it to descend and correct the connector in the auxiliary cavity, ensuring that the connectors are neatly arranged and accurately positioned. Subsequently, the third hydraulic cylinder pushes the insertion board back to its original position again. This action not only effectively separates the bottom-layer connector from the upper-layer connectors, preventing mutual interference, but also prepares for the next feeding of the connectors, improving the automation degree and accuracy of connector processing, reducing the need for manual intervention. At the same time, it realizes precise control and correction of the connector position, guarantees product quality, and also improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0039] Embodiment 1: As Figures 1 to 9 shown, the integrated small-pitch board-to-board connector and processing technology described in the embodiment of the present invention specifically include the following steps:

[0040] Step 1, connector production: First, through die casting with a mold, a connector body is produced, and then it is cooled, demolded and transported, and transported to a pin inserter for pin insertion work;

[0041] Step 2, pin insertion: The completed connector body is transported into the pin inserter through a transfer device, and then metal pins are inserted on one side of the connector. After the side-by-side insertion is completed, the connector is bent;

[0042] Step 3, bending and packaging: The connector after pin insertion is placed in the clamping frame 25 on the bending machine for fixation, and then the bending machine is started to bend the pins of the connector, thus completing the production of the integrated small-pitch board-to-board connector. Then the bent connector is removed and packaged, and thus the production of the connector is completed.

[0043] As Figure 1 and Figure 5 shown, the work of the bending machine in Step 3 of this embodiment is specifically as follows. First, a workbench 21 is provided on the upper surface of the machine body 2. When performing the connection processing and bending process, the connector that has completed the pin insertion process is placed in the clamping frame 25 on the upper surface of the workbench 21 through the loading and unloading integrated component. After the connector is placed in the clamping frame 25, the bending block on the upper surface of the bending machine body 2 is started to bend the pins of the connector.

[0044] Specifically, the connector is fixed by the clamping frame 25, and then the integrated work of the loading and unloading component makes the loading and unloading process of the connector more convenient, and the automated loading and unloading reduces human errors and improves production efficiency.

[0045] As Figure 5As shown in the figure, a lifting member is provided inside the workbench 21 of this embodiment. After the bending operation is completed, the electric push rod 210 is activated. The electric push rod 210 drives the fixed rod 211, and the fixed rod 211 squeezes the air inside the fixed cavity 26, increasing the internal air pressure. Then, it squeezes the top column 27 to move upward along the vertical fixed cavity 26, and it will drive the compression spring 28. The upward movement of the top column 27 will lift the top block 29, and the top block 29 will then lift the bent connector, completing the blanking and ejection of the connector.

[0046] Specifically, the electric push rod 210 drives the fixed rod 211 to compress the air inside the fixed cavity 26. Utilizing the increased air pressure to push the top column 27 to rise vertically, while stretching the compression spring 28 to store energy. When the top column 27 moves upward, the top block 29 rises accordingly, lifting the bent connector, realizing rapid blanking and ejection. This not only improves production efficiency but also reduces manual operation and labor intensity. At the same time, by utilizing the dual effects of air pressure and the spring 38, the smoothness and reliability of the ejection action are ensured. After the ejection is completed, the top block 29 can automatically reset under the action of the restoring force of the compression spring 28, so it can be used continuously in a cycle, facilitating the next ejection.

[0047] As Figure 6 shown in the figure, during the process of the top block 29 of this embodiment lifting the connector, the guide rail 31 on the fixed frame 3 on the surface of the machine body 2 is activated, causing the slide table 32 in the guide rail 31 to drive the fixed frame 35 to slide along the guide rail 31 to directly above the clamping frame 25, and the upper surface of the fixed frame 35 abuts against the upper surface of the clamping frame 25. After the clamping frame 25 moves to directly above, it cooperates with the lifting member to perform the blanking work of the connector.

[0048] Specifically, when the top block 29 lifts the connector, the guide rail 31 on the fixed frame 3 on the surface of the machine body 2 is activated synchronously, driving the slide table 32 and the fixed frame 35 thereon to slide along the guide rail 31 to directly above the clamping frame 25, and making the upper surface of the fixed frame 35 abut against the upper surface of the clamping frame 25. Subsequently, the clamping frame 25 and the lifting member work together to complete the blanking of the connector. Through the cooperation of the guide rail 31 and the slide table 32, the precise positioning and rapid movement of the fixed frame 35 and the clamping frame 25 are achieved, improving the blanking efficiency and accuracy. At the same time, it also enhances the automation and coordination of the entire blanking process, further improving the overall efficiency of the production line.

[0049] As Figure 6 and Figure 7 shown in the figure, after the fixed frame 35 of this embodiment moves to directly above the clamping frame 25, the top block 29 of the lifting member will push the bent connector into the fixed frame 35. When the connector enters the fixed frame 35, it will squeeze one group of clamping blocks 36 inside the fixed frame 35. The clamping blocks 36 on both sides of the clamping block 36 squeeze the spring 38 and retract into the connecting groove 37. Then the connector will just be stuck between the two groups of clamping blocks 36, and then it will move to directly below the auxiliary frame 5 under the drive of the guide rail 31.

[0050] Specifically, when the top block 29 of the lifting member pushes the bent connector into the fixed frame 35, at this time, the connector squeezes one set of clamping blocks 36 in the fixed frame 35, and the springs 38 on both sides of the clamping blocks 36 retract into the connecting grooves 37, and then the connector enters the fixed frame 35. Then, the connector body is stuck between the two sets of clamping blocks 36, thus realizing the firm clamping of the connector between the two sets of clamping blocks 36. Subsequently, driven by the guide rail 31, the fixed frame 35 carries the connector and moves to directly below the auxiliary frame 5 to prepare for feeding and discharging. Through the cooperation of the clamping blocks 36 and the springs 38, the rapid fixing and releasing of the connector are realized, improving the automation degree and operation efficiency of the production line. At the same time, the stability and safety of the connector during the transfer process are also ensured.

[0051] As Figure 6 shown, after the fixed frame 35 of this embodiment clamps the bent connector, the guide rail 31 is started to drive the sliding table 32, and then drive the fixed frame 35 to slide along the guide rail 31 to directly below the auxiliary frame 5. During the process of the sliding table 32 driving the fixed frame 35 to move, the sliding table 32 is rotatably connected to the gear 33. Therefore, the rotating columns 34 on both sides of the fixed frame 35 rotate along the rack plate 39 with the gears 33 at their ends. The rotation of the rotating columns 34 then drives the fixed frame 35 to flip, so that it just flips to directly below the auxiliary frame 5, and the connector is also flipped accordingly. In this way, the pins of the bent connector will be perpendicular to the ground.

[0052] The pins of the flipped connector are perpendicular to the ground, which is convenient for protecting the pins during the discharging process of the connector and can directly observe the bending condition of the pins of the connector, facilitating detection.

[0053] As Figure 8 and Figure 9 shown, after the fixed frame 35 of this embodiment flips to directly below the auxiliary frame 5, the second hydraulic cylinder 212 is started to push the plug board 214 at its output end to abut against the partition board 52. At this time, the partition board 52 will extend out of the auxiliary frame 5 and gradually abut against the fixed frame 35. When the auxiliary frame 5 is about to abut against the fixed frame 35, one of the third hydraulic cylinders 41 on one side of the support frame 4 is started, and the third hydraulic cylinder 41 drives the positioning plate 55 at its output end to disengage from the auxiliary frame 5, releasing the connector that has not been bent at the bottom end of the auxiliary frame 5. Then, the bottom end of the auxiliary frame 5 is closed, and by staggering the fixed frame 35 and the auxiliary frame 5 by a certain distance, the limiting frame 54 at the end of the partition board 52 is driven to push the unbent connector and push it between the two sets of clamping blocks 36. During the process of the plug board 214 limiting the discharging of the connector through the partition board 52, when the limiting is completed and the second hydraulic cylinder 212 resets, the partition board 52 automatically resets under the action of the connecting spring 53, so as to perform the next limiting work.

[0054] Specifically, through the synergistic effect of the third hydraulic cylinder 41 and the second hydraulic cylinder 212, the unbent connector is pushed out of the bent connector in the fixed frame 35. Moreover, the clamping block 36 in the fixed frame 35 can pre-bend the pins of the connector through its conical setting, thereby reducing the rigidity damage caused by direct bending. At the same time, the automated loading and unloading improve the bending efficiency of the connector, thus accelerating the production progress and improving the production quality.

[0055] Embodiment 2: As Figures 1 to 9 shown, compared with Embodiment 1, another implementation manner of the present invention is as follows: during the process that the insertion plate 214 drives the partition plate 52 to push and press the connector in the misaligned fixed frame 35, start one of the third hydraulic cylinders 41 to retract the insertion piece 56. Then, when the limit frame 54 pushes the connector into the fixed frame 35, the extrusion block 213 on the top wall of the insertion plate 214 will squeeze the connector on the auxiliary top layer to descend, so as to correct the connector in the auxiliary cavity 51. Then, the third hydraulic cylinder 41 pushes the insertion plate 214 to insert back again, separating the lowermost connector from the upper connectors, and preparing for the next feeding of the connector.

[0056] Specifically, during the process that the insertion plate 214 drives the partition plate 52 to push and press the connector in the misaligned fixed frame 35, start one of the third hydraulic cylinders 41 to retract the insertion piece 56 in a timely manner. Because the extrusion block 213 on the top wall of the insertion plate 214 will squeeze the connector on the top layer, causing it to descend and correct the connector in the auxiliary cavity 51, ensuring that the connectors are neatly arranged and accurately positioned. Subsequently, the third hydraulic cylinder 41 pushes the insertion plate 214 to insert back to its original position again. This action not only effectively separates the lowermost connector from the upper connectors, preventing mutual interference, but also prepares for the next feeding of the connector, improving the automation degree and accuracy of connector processing, reducing the need for manual intervention. At the same time, it realizes precise control and correction of the connector position, ensures product quality, and also improves production efficiency.

[0057] Working principle: First, a workbench 21 is provided on the upper surface of the machine body 2. When performing the connection processing and bending process, the connector that has completed the pin insertion process is placed in the clamping frame 25 on the upper surface of the workbench 21 through the loading and unloading integrated component. After the connector is placed in the clamping frame 25, start the bending block on the upper surface of the bending machine body 2 to bend the pins of the connector. The connector is fixed by the clamping frame 25. Then, through the integrated work of the loading and unloading component, the loading and unloading process of the connector is more convenient, and the automated loading and unloading reduce human errors and improve production efficiency;

[0058] Then, the electric push rod 210 drives the fixed rod 211 to compress the air in the fixed cavity 26. The increased air pressure is used to push the ejector pin 27 to rise vertically. At the same time, the compression spring 28 is stretched to store energy. When the ejector pin 27 moves upward, the ejector block 29 rises accordingly, lifting the bent connector, realizing rapid blanking and ejecting and disassembling. This not only improves production efficiency but also reduces manual operation and labor intensity. At the same time, the dual effects of air pressure and the spring 38 ensure the smoothness and reliability of the ejecting and disassembling action. After the ejecting and disassembling are completed, the ejector block 29 can automatically reset under the restoring force of the compression spring 28, so it can be continuously used in a cycle, facilitating the next ejecting and disassembling;

[0059] When the ejector block 29 of the ejector lifts the connector, the guide rail 31 on the fixed frame 3 on the surface of the machine body 2 is started synchronously, driving the slide table 32 and the fixed frame 35 thereon to slide along the guide rail 31 to directly above the clamping frame 25, and making the upper surface of the fixed frame 35 abut against the upper surface of the clamping frame 25. Subsequently, the clamping frame 25 and the ejecting member work together to complete the blanking of the connector. Through the cooperation of the guide rail 31 and the slide table 32, the precise positioning and rapid movement of the fixed frame 35 and the clamping frame 25 are realized, improving the blanking efficiency and accuracy. At the same time, it also enhances the automation and coordination of the entire blanking process, further improving the overall efficiency of the production line;

[0060] At the same time, when the ejector block 29 of the ejector pushes the bent connector into the fixed frame 35, at this time, the connector squeezes one set of clamping blocks 36 in the fixed frame 35. The springs 38 on both sides of the clamping blocks 36 retract into the connecting grooves 37, and then the connector enters the fixed frame 35. Then, the connector body will be stuck between the two sets of clamping blocks 36, thus realizing the firm clamping of the connector between the two sets of clamping blocks 36. Subsequently, driven by the guide rail 31, the fixed frame 35 carries the connector and moves to directly below the auxiliary frame 5 to prepare for feeding and blanking. Through the cooperation of the clamping blocks 36 and the springs 38, the rapid fixing and release of the connector are realized, improving the automation degree and operation efficiency of the production line. At the same time, it also ensures the stability and safety of the connector during the transfer process;

[0061] After the fixed frame 35 clamps the bent connector, the guide rail 31 is started to drive the slide table 32, and then drive the fixed frame 35 to slide along the guide rail 31 to directly below the auxiliary frame 5. During the process of the slide table 32 driving the fixed frame 35 to move, the slide table 32 is rotatably connected to the gear 33. Therefore, the rotating columns 34 on both sides of the fixed frame 35 rotate along the rack plate 39 with the gears 33 at their ends. The rotation of the rotating columns 34 then drives the fixed frame 35 to turn over, so that it just turns to directly below the auxiliary frame 5, and the connector is also turned over accordingly, so that the pins of the bent connector will be vertically facing the ground;

[0062] The turned-over connector pins are perpendicular to the ground, which is convenient for protecting the pins during the connector blanking process and can directly observe the bending condition of the connector pins, facilitating detection;

[0063] After the fixed frame 35 is turned over to be directly below the auxiliary frame 5, the insertion plate 214 at the output end of the second hydraulic cylinder 212 is pushed to abut against the partition plate 52 by starting the second hydraulic cylinder 212. At this time, the partition plate 52 will extend out of the auxiliary frame 5 and gradually abut against the fixed frame 35. When the auxiliary frame 5 is about to abut against the fixed frame 35, one of the third hydraulic cylinders 41 on one side of the support frame 4 is started, and the positioning plate 55 at the output end of the third hydraulic cylinder 41 disengages from the auxiliary frame 5, releasing the connector at the bottommost end of the auxiliary frame 5 that has not been bent. Then, the bottom end of the auxiliary frame 5 is closed, and by staggering the fixed frame 35 and the auxiliary frame 5 by a certain distance, the limiting frame 54 at the end of the partition plate 52 is driven to push the unbent connector and push it between the two sets of clamping blocks 36. During the process of the insertion plate 214 limiting the blanking of the connector through the partition plate 52, when the limiting is completed and the second hydraulic cylinder 212 resets, the partition plate 52 automatically resets under the action of the connecting spring 53, so as to perform the next limiting work;

[0064] Finally, during the process of the insertion plate 214 driving the partition plate 52 to push and press the connector in the misaligned fixed frame 35, one of the third hydraulic cylinders 41 is started in a timely manner to retract the insertion piece 56. Because the extrusion block 213 on the top wall of the insertion plate 214 will squeeze the top-layer connector, causing it to descend and correct the connector in the auxiliary cavity 51 to ensure that the connectors are neatly arranged and accurately positioned. Subsequently, the third hydraulic cylinder 41 pushes the insertion plate 214 back to its original position again. This action not only effectively separates the bottommost connector from the upper-layer connectors, preventing mutual interference, but also prepares for the next feeding of the connectors, improving the automation degree and accuracy of connector processing, reducing the need for manual intervention. At the same time, it realizes the precise control and correction of the connector position, guarantees the product quality, and also improves the production efficiency.

The integrated small pitch board-to-board connector processing process according to claim 1 is characterized in that: When the ejector block (29) is lifting the connector, the guide rail (31) on the fixed frame (3) on the surface of the machine body (2) is activated, so that the slide (32) in the guide rail (31) slides along the guide rail (31) with the fixed frame (35) to the top of the card frame (25), and the fixed frame (35) abuts against the upper surface of the card frame (25). After the card frame (25) moves to the top, it cooperates with the ejector to carry out the connector unloading work.

3. The integrated small pitch board-to-board connector processing process according to claim 2 is characterized in that: After the fixed frame (35) moves to the top of the card frame (25), the top block (29) of the lifting member will push the bent connector into the fixed frame (35). When the connector enters the fixed frame (35), it will squeeze one group of card blocks (36) in the fixed frame (35). The card blocks (36) on both sides of the card blocks (36) squeeze the springs (38) into the connection groove (37). Then, the connector will be just stuck between the two groups of card blocks (36) and then moved to the bottom of the auxiliary frame (5) driven by the guide rail (31).

4. The integrated small pitch board-to-board connector processing process according to claim 3 is characterized in that: After the fixed frame (35) has clamped the bent connector, the guide rail (31) is started to drive the slide (32), thereby driving the fixed frame (35) to slide along the guide rail (31) to the bottom of the auxiliary frame (5). In the process of the slide (32) driving the fixed frame (35) to move, the slide (32) is rotationally connected to the gear (33), so that the rotating columns (34) on both sides of the fixed frame (35) rotate along the rack plate (39) along with the gear (33) at the end thereof. The rotation of the rotating columns (34) drives the fixed frame (35) to flip over, so that it flips over to the bottom of the auxiliary frame (5), and the connector is also flipped over, so that the bent connector pins are vertically facing the ground.

5. The integrated small pitch board-to-board connector processing process according to claim 4 is characterized in that: After the fixed frame (35) is flipped to the position directly below the auxiliary frame (5), the plug plate (214) at the output end thereof is pushed to abut against the partition plate (52) by starting the second hydraulic cylinder (212). At this time, the partition plate (52) extends out of the auxiliary frame (5) and gradually abuts against the fixed frame (35). When the auxiliary frame (5) and the fixed frame (35) are about to abut, one of the third hydraulic cylinders (41) on one side of the support frame (4) is started. The third hydraulic cylinder (41) drives the positioning plate (55) at the output end thereof to separate from the auxiliary frame (5), releases the unbent connector at the bottom end of the auxiliary frame (5), and then closes the bottom end of the auxiliary frame (5). By dislocating the fixed frame (35) and the auxiliary frame (5), the limit frame (54) at the end of the partition plate (52) is driven to push the unbent connector to between the two groups of card blocks (36).

6. The integrated small pitch board-to-board connector processing process according to claim 5 is characterized in that: During the process of the plug plate (214) limiting the unloading of the connector through the partition plate (52), when the limiting is completed and the second hydraulic cylinder (212) is reset, the partition plate (52) is automatically reset under the action of the connecting spring (53), thereby performing the next limiting operation.

7. The integrated small pitch board-to-board connector processing process according to claim 6 is characterized in that: When the plug plate (214) drives the partition plate (52) to push the connector in the misaligned fixed frame (35), one of the third hydraulic cylinders (41) is started to retract the plug plate (56). Then, when the limit frame (54) pushes the connector into the fixed frame (35), the extrusion block (213) on the top wall of the plug plate (214) squeezes the connector on the auxiliary top layer to descend, and corrects the connector in the auxiliary cavity (51). Then, the third hydraulic cylinder (41) pushes the plug plate (214) back again, and separates the connector on the bottom layer from the connector on the upper layer, so as to prepare for the next connector loading.

8. An integrated small pitch board-to-board connector, characterized in that: Obtained by the processing technology of the integrated small-pitch board-to-board connector according to any one of claims 1-7 above.
