Description

Technical Field

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

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

[0003] In the process of producing an integrated small-pitch board-to-board connector with prior art, when the pin insertion device completes the pin insertion work, the pin insertion device will arrange and store the connectors, and then the staff will take out the connectors one by one, place the connectors on the workbench of the bending machine, and squeeze the pins by rotating the bending block on the workbench to complete the bending of the pins. After the bending work is completed, the staff will remove the connector and place the next connector for pin bending.

[0004] However, during the operation of the existing bending machine, after the pin insertion device completes 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, and the staff takes out the connector after the bending is completed. This loading and unloading process of a single connector needs to be repeated many times, which makes the connector bending efficiency low, and each time the connector is placed on the bending machine, it needs to be aligned and calibrated, which increases the bending time and causes the problem of low production efficiency.

[0005] To this end, the present invention provides an integrated small-pitch board-to-board connector and a processing technology. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the integrated small-pitch board-to-board connector and processing technology described in the present invention, the specific steps include: step 1, connector production: first, the connector body is produced by die casting, and then cooled, demolded and transported, and transported to the pin insertion machine for pin insertion; Step 2: Inserting the pin: The completed connector body is transported to the pin insertion machine through the transfer device, and then the metal pin is inserted into one side of the connector. After the pins are inserted side by side, the connector is bent; Step 3: Bending and packaging: Place the connector with the pins inserted in the card frame on the bending machine for fixation, then start the bending machine to bend the pins, thereby completing the production of the integrated small-pitch board-to-board connector, and then remove the bent connector for packaging to complete the production of the connector.

[0008] Preferably, the operation of the bending machine in step three is specifically as follows: first, a workbench is set 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 card frame on the upper surface of the workbench through the loading and unloading integrated components. After the connector is placed in the card frame, the bending block on the upper surface of the bending machine body is started to bend the connector pins.

[0009] Preferably, a lifting piece is provided inside the workbench. When the bending work is completed, the electric push rod is started, and the electric push rod drives the fixed rod. The fixed rod squeezes the air in the fixed cavity to increase the internal air pressure, thereby squeezing the lift column to move upward along the vertical fixed cavity, and will drive the compression spring. The upward movement of the lift column will lift the lift block, and the lift block will then lift the bent connector to complete the unloading and removal of the connector.

[0010] Preferably, when the top block lifts the connector, the guide rail on the fixed frame on the surface of the body is started, so that the slide in the guide rail slides along the guide rail with the fixed frame to just above the card frame, and the fixed frame abuts against the upper surface of the card frame. After the card frame moves to just above, it cooperates with the lifting piece to carry out the unloading work of the connector.

[0011] Preferably, after the fixed frame moves to the top of the card frame, the top block of the lifting member will push the bent connector into the fixed frame. When the connector enters the fixed frame, it will squeeze one group of card blocks in the fixed frame. The card block squeezing springs on both sides of the card block will retract into the connecting groove. Then the connector will be just stuck between the two groups of card blocks, and then moved to the bottom of the auxiliary frame under the drive of the guide rail.

[0012] Preferably, after the fixed frame clamps the bent connector, the guide rail is started to drive the slide, which in turn drives the fixed frame to slide along the guide rail to the bottom of the auxiliary frame. In the process of the slide driving the fixed frame to move, the slide is connected to the gear rotation, so that 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 in turn drives the fixed frame to flip over, so that it flips just below the auxiliary frame, and the connector is then also flipped, so that the bent connector pins will be vertically facing the ground.

[0013] Preferably, after the fixed frame is flipped to the bottom of the auxiliary frame, the second hydraulic cylinder is started to push the plug plate at its output end to abut against the partition. At this time, the partition will extend out of the auxiliary frame and gradually abut against the fixed frame. When the auxiliary frame is about to abut against the fixed frame, one of the third hydraulic cylinders on the side of the support frame is started. The third hydraulic cylinder drives the positioning plate at its output end to detach from the auxiliary frame, releasing the unbent connector at the bottom of the auxiliary frame, and then closes the bottom end of the auxiliary frame. By offsetting the fixed frame and the auxiliary frame by a certain distance, the limit frame at the end of the partition is driven to push the unbent connector and push it between the two sets of blocks.

[0014] Preferably, during the process of the plug plate limiting the unloading of the connector through the partition, when the limiting is completed and the second hydraulic cylinder is reset, the partition is automatically reset under the action of the connecting spring, thereby performing the next limiting work.

[0015] Preferably, during the process of the plug plate driving the partition to push the connector in the misplaced fixed frame, one of the third hydraulic cylinders is started to retract the plug plate, and then when the limit frame pushes the connector into the fixed frame, the extrusion block on the top wall of the plug plate will squeeze the connector on the auxiliary top layer to descend, and correct the connector in the auxiliary cavity, and then the third hydraulic cylinder pushes the plug plate back again to separate the connector on the bottom layer from the connector on the upper layer, preparing for the next loading of the connector.

[0016] One-piece small pitch board-to-board connector.

[0017] The beneficial effects of the present invention are as follows: 1. The integrated small-pitch board-to-board connector and processing technology described in the present invention fixes the connector through a card frame, and then integrates the loading and unloading components, making the loading and unloading process of the connector more convenient, and the automated loading and unloading reduces manual errors and improves production efficiency.

[0018] 2. The integrated small-pitch board-to-board connector and processing technology described in the present invention drives the fixed rod through an electric push rod to compress the air in the fixed cavity, and uses the increased air pressure to push the top column up in the vertical direction, while stretching the compression spring to store energy. When the top column moves up, the top block rises accordingly, and lifts up the bent connector to achieve rapid unloading and disassembly, which not only improves production efficiency, but also reduces manual operation and labor intensity. At the same time, the dual effects of air pressure and springs are used to ensure the smoothness and reliability of the disassembly action. After the disassembly is completed, the top block can automatically reset under the reset force of the compression spring, so that it can be used continuously in a cycle, which is convenient for the next disassembly.

[0019] 3. The integrated small-pitch board-to-board connector and processing technology described in the present invention, by timely starting one of the third hydraulic cylinders to retract the plug in the process of the plug driving the partition to push the connector in the misaligned fixing frame, because the extrusion block on the top wall of the plug will squeeze the connector on the top layer, causing it to drop and correct the connector in the auxiliary cavity, ensuring that the connectors are arranged neatly and positioned accurately, and then the third hydraulic cylinder pushes the plug back to its original position again. This action not only effectively separates the connector on the bottom layer from the connector on the upper layer to prevent mutual interference, but also prepares for the next loading of the connector, improves the automation and accuracy of connector processing, reduces the need for manual intervention, and at the same time, realizes precise control and correction of the connector position, ensures product quality, and also improves production efficiency.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] Embodiment 1: Figures 1 to 9 As 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: Step 1: Connector production: First, the connector body is produced through die casting, and then cooled, demolded and transported to the pin insertion machine for pin insertion; Step 2: Inserting the pin: The completed connector body is transported to the pin insertion machine through the transfer device, and then the metal pin is inserted into one side of the connector. After the pins are inserted side by side, the connector is bent; Step 3: Bending and packaging: Place the connector with the pins inserted into the card frame 25 on the bending machine for fixation, then start the bending machine to bend the pins, thereby completing the production of the integrated small-pitch board-to-board connector, and then remove the bent connector for packaging to complete the production of the connector.

[0025] like Figure 1 and Figure 5 As shown, the operation of the bending machine in step three of this embodiment is specifically as follows: first, a workbench 21 is set on the upper surface of the body 2. When the connection processing and bending process is performed, the connector that has completed the pin insertion process is placed in the card frame 25 on the upper surface of the workbench 21 through the loading and unloading integrated components. After the connector is placed in the card frame 25, the bending block on the upper surface of the bending machine body 2 is started to bend the connector pins.

[0026] Specifically, the connector is fixed by the clamping frame 25, and then the loading and unloading components are integrated, so that the loading and unloading process of the connector is more convenient, and the automated loading and unloading reduces manual errors and improves production efficiency.

[0027] like Figure 5 As shown, the workbench 21 described in this embodiment is provided with a lifting piece inside. When the bending work is completed, the electric push rod 210 is started, and the electric push rod 210 drives the fixed rod 211. The fixed rod 211 squeezes the air in the fixed cavity 26 to increase the internal air pressure, thereby squeezing the lift column 27 to move upward along the vertical fixed cavity 26, and will drive the compression spring 28. The upward movement of the lift column 27 will lift the lift block 29, and the lift block 29 will then lift the bent connector to complete the unloading and removal of the connector.

[0028] Specifically, the electric push rod 210 drives the fixed rod 211 to compress the air in the fixed cavity 26, and the increased air pressure is used to push the top column 27 up in the vertical direction, while stretching the compression spring 28 to store energy. When the top column 27 moves up, the top block 29 rises accordingly, and lifts up the bent connector to achieve rapid unloading and dismantling, which not only improves production efficiency, but also reduces manual operation and labor intensity. At the same time, the dual effects of air pressure and spring 38 are used to ensure the smoothness and reliability of the dismantling action. After the dismantling is completed, the top block 29 can automatically reset under the reset force of the compression spring 28, so that it can be used continuously in a cycle, which is convenient for the next dismantling.

[0029] like Figure 6 As shown, in the process of the ejection block 29 of the present embodiment ejecting the connector, the guide rail 31 on the fixed frame 3 on the surface of the body 2 is started, so that the slide 32 in the guide rail 31 slides along the guide rail 31 with the fixed frame 35 to just above 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 just above, it cooperates with the ejection member to carry out the unloading work of the connector.

[0030] Specifically, when the top block 29 lifts the connector, the guide rail 31 on the fixed frame 3 on the surface of the body 2 starts synchronously, driving the slide 32 and the fixed frame 35 on it to slide along the guide rail 31 to just above the card frame 25, and making the fixed frame 35 abut against the upper surface of the card frame 25. Subsequently, the card frame 25 and the lifting member work together to complete the unloading of the connector. Through the cooperation of the guide rail 31 and the slide 32, the fixed frame 35 and the card frame 25 are accurately positioned and quickly moved, thereby improving the unloading efficiency and accuracy. At the same time, it also enhances the automation and coordination of the entire unloading process, further improving the overall efficiency of the production line.

[0031] like Figure 6 and Figure 7 As shown, after the fixed frame 35 described in this embodiment moves to just above 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 block 36 squeeze the springs 38 into the connecting groove 37, and then the connector will be just stuck between the two groups of card blocks 36, and then moved to just below the auxiliary frame 5 driven by the guide rail 31.

[0032] Specifically, when the top block 29 of the lifting member pushes the bent connector into the fixed frame 35, the connector squeezes one group of blocks 36 in the fixed frame 35, and the springs 38 on both sides of the blocks 36 retract into the connecting groove 37, and the connector then enters the fixed frame 35, and then the connector is stuck between the two groups of blocks 36, thereby achieving a firm clamping of the connector between the two groups of blocks 36. Subsequently, driven by the guide rail 31, the fixed frame 35 carries the connector and moves to the bottom of the auxiliary frame 5 to prepare for loading and unloading. Through the cooperation of the blocks 36 and the springs 38, the connector is quickly fixed and released, which improves the automation level and operating efficiency of the production line. At the same time, it also ensures the stability and safety of the connector during the transfer process.

[0033] like Figure 6 As shown, after the fixed frame 35 of this embodiment clamps 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 rotatably connected with the gear 33, so the rotating columns 34 on both sides of the fixed frame 35 rotate along the rack plate 39 along with the gear 33 at its end. The rotation of the rotating columns 34 drives the fixed frame 35 to flip over, so that it just flips over to the bottom of the auxiliary frame 5, and the connector is also flipped, so that the bent connector pins will be vertically facing the ground; The flipped connector pins are perpendicular to the ground, which is convenient for protecting the pins during the connector cutting process, and the bending condition of the connector pins can be directly observed for easy detection.

[0034] like Figure 8 and Fig. 9 As shown, after the fixed frame 35 described in this embodiment is flipped to the bottom of the auxiliary frame 5, the second hydraulic cylinder 212 is started to push the plug plate 214 at its output end to abut against the partition 52. At this time, the partition 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. The third hydraulic cylinder 41 drives the positioning plate 55 at its output end to disengage from the auxiliary frame 5, releasing the unbent connector at the bottom end of the auxiliary frame 5, and then closes the bottom end of the auxiliary frame 5, and through the fixed frame 35 and the auxiliary frame 5 are displaced by a certain distance, the limit frame 54 at the end of the partition 52 is driven to push the unbent connector and push it between the two groups of blocks 36. In the process of the plug plate 214 limiting the connector by the partition 52, when the limit is completed and the second hydraulic cylinder 212 is reset, the partition 52 is automatically reset under the action of the connecting spring 53, so as to perform the next limiting work.

[0035] Specifically, through the coordinated action of the third hydraulic cylinder 41 and the second hydraulic cylinder 212, the unbent connector pushes the bent connector in the fixed frame 35 out, and the block 36 in the fixed frame 35 can pre-bend the connector pins through the conical setting, thereby reducing the rigid damage caused by direct bending. At the same time, the automated loading and unloading improves the bending efficiency of the connector, thereby speeding up the production progress and improving the production quality.

[0036] Embodiment 2: Figures 1 to 9 As shown, compared with Example 1, another implementation of the present invention is: when the plug plate 214 drives the partition plate 52 to push the connector in the offset fixing frame 35, one of the third hydraulic cylinders 41 is started to retract the plug 56, and then when the limit frame 54 pushes the connector into the fixing frame 35, the extrusion block 213 on the top wall of the plug plate 214 will squeeze the connector on the auxiliary top layer to descend, and correct the connector in the auxiliary cavity 51, and then the third hydraulic cylinder 41 pushes the plug plate 214 back again to separate the bottom layer connector from the upper layer connector, preparing for the next connector loading.

[0037] Specifically, in the process of the plug plate 214 driving the partition plate 52 to push the connector in the offset fixing frame 35, one of the third hydraulic cylinders 41 is started in time to retract the plug 56, because the extrusion block 213 on the top wall of the plug plate 214 will squeeze the connector on the top layer, causing it to drop and correct the connector in the auxiliary cavity 51 to ensure that the connectors are arranged neatly and positioned accurately. Subsequently, the third hydraulic cylinder 41 pushes the plug plate 214 back to its original position again. This action not only effectively separates the connectors on the bottom layer from the connectors on the upper layer to prevent mutual interference, but also prepares for the next loading of the connector, thereby improving the automation and accuracy of connector processing, reducing the need for manual intervention, and at the same time, achieving precise control and correction of the connector position, ensuring product quality, and also improving production efficiency.

[0038] Working principle: first, a workbench 21 is arranged on the upper surface of the machine body 2. When the connection processing and bending process is performed, the connector that has completed the pin insertion process is placed in the card frame 25 on the upper surface of the workbench 21 through the loading and unloading integrated assembly. After the connector is placed in the card frame 25, the bending block on the upper surface of the bending machine body 2 is started to bend the connector pins. The connector is fixed by the card frame 25, and then the integration of the loading and unloading assembly makes the loading and unloading process of the connector more convenient, and the automated loading and unloading reduces manual errors and improves production efficiency. Then, the electric push rod 210 drives the fixed rod 211 to compress the air in the fixed cavity 26, and the increased air pressure is used to push the top column 27 up in the vertical direction, while stretching the compression spring 28 to store energy. When the top column 27 moves up, the top block 29 rises accordingly, and the bent connector is lifted up, so as to achieve fast material unloading and top removal, which not only improves production efficiency, but also reduces manual operation and labor intensity. At the same time, the dual effects of air pressure and spring 38 are used to ensure the smoothness and reliability of the top removal action. After the top removal is completed, the top block 29 can be automatically reset under the reset force of the compression spring 28, so that it can be used continuously in a cycle, which is convenient for the next top removal. When the top block 29 lifts up the connector, the guide rail 31 on the fixed frame 3 on the surface of the body 2 is started synchronously, driving the slide 32 and the fixed frame 35 thereon to slide along the guide rail 31 to just above the card frame 25, and making the fixed frame 35 abut against the upper surface of the card frame 25. Then, the card frame 25 and the lifting member work together to complete the unloading of the connector. Through the cooperation of the guide rail 31 and the slide 32, the fixed frame 35 and the card frame 25 are accurately positioned and quickly moved, which improves the unloading efficiency and accuracy. At the same time, it also enhances the automation and coordination of the entire unloading process, further improving the overall efficiency of the production line. At the same time, when the top block 29 of the lifting member pushes the bent connector into the fixed frame 35, the connector squeezes one of the groups of blocks 36 in the fixed frame 35, and the springs 38 on both sides of the blocks 36 are retracted into the connecting grooves 37, and the connector then enters the fixed frame 35, and then the connector is stuck between the two groups of blocks 36, so that the connector is firmly clamped between the two groups of blocks 36. Subsequently, driven by the guide rail 31, the fixed frame 35 carries the connector and moves to the bottom of the auxiliary frame 5 to prepare for loading and unloading. Through the cooperation of the blocks 36 and the springs 38, the connector is quickly fixed and released, which improves 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. After the fixed frame 35 has clamped the bent connector, the guide rail 31 is started to drive the slide 32, and then the fixed frame 35 is driven 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 connected to the gear 33 for rotation, 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 its end. The rotation of the rotating columns 34 drives the fixed frame 35 to flip over, so that it just flips over to the bottom of the auxiliary frame 5, and the connector is also flipped, so that the bent connector pins will be vertically facing the ground; The flipped connector pins are perpendicular to the ground, which is convenient for protecting the pins during the connector cutting process, and the bending condition of the connector pins can be directly observed for easy detection; When the auxiliary frame 5 is about to abut against the fixed frame 35, the third hydraulic cylinder 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 unbent connector at the bottom of the auxiliary frame 5, and then closes the bottom end of the auxiliary frame 5, and displaces the fixed frame 35 and the auxiliary frame 5 by a certain distance, drives the limit frame 54 at the end of the partition 52 to push the unbent connector to between the two groups of blocks 36, and in the process of limiting the blanking of the connector by the insert plate 214 through the partition 52, when the limit is completed and the second hydraulic cylinder 212 is reset, the partition 52 is automatically reset under the action of the connecting spring 53, so as to perform the next limit work; Finally, when the plug plate 214 drives the partition plate 52 to push the connector in the offset fixing frame 35, one of the third hydraulic cylinders 41 is started in time to retract the plug plate 56, because the extrusion block 213 on the top wall of the plug plate 214 will squeeze the connector on the top layer, causing it to drop and correct the connector in the auxiliary cavity 51 to ensure that the connectors are arranged neatly and positioned accurately. Subsequently, the third hydraulic cylinder 41 pushes the plug plate 214 back to its original position again. This action not only effectively separates the connectors on the bottom layer from the connectors on the upper layer to prevent mutual interference, but also prepares for the next loading of the connector, improves the automation and accuracy of connector processing, reduces the need for manual intervention, and at the same time, achieves precise control and correction of the connector position, ensures product quality, and improves production efficiency.

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.

7. The integrated small pitch board-to-board connector processing process according to claim 6 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).

8. The integrated small pitch board-to-board connector processing process according to claim 7 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.

9. The integrated small pitch board-to-board connector processing process according to claim 7 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.

10. 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 1-9 above.
