Abstract

This invention discloses a piercing device for connector assembly, relating to the field of connector assembly technology. It includes a base and an alignment component. A support frame is mounted on the top of the base, and an electric cylinder is mounted on the top of the support frame. A lifting frame is connected to the bottom of the electric cylinder, and a pressure head is mounted at the center of the bottom of the lifting frame. A positioning seat is mounted at the center of the top of the base, and the alignment component is located on the top of the base. When a wire is inserted into a hole on the connector, the electric cylinder is activated, causing the lifting frame to move down a short distance. At this time, the pressure rod presses against the inclined plate, aligning the two slots at the bottom of the guide sleeve with the two slots at the top of the alignment seat. Because the upper part of the guide sleeve is wider, it facilitates the insertion of the wire. After insertion, the wire falls under the guide into the slot at the top of the alignment seat, enabling rapid wire alignment. Furthermore, a partition is used to divide the interior of the guide sleeve, allowing two wires to be placed simultaneously.

Description

Technical Field

[0001] This invention relates to the field of connector assembly technology, specifically to a piercing device for connector assembly. Background Technology

[0002] Connectors are plug-in components used to connect electronic devices. The connector is assembled by inserting the corresponding wire into the wire hole. Piercing connectors connect directly to the conductor by piercing the insulation layer of the wire during assembly, eliminating the need for complicated stripping, soldering and other processing steps, thus greatly improving the efficiency and reliability of the connection.

[0003] For example, patent CN216121142U discloses a safety pop-out connector piercing device. This patent utilizes a safety pop-out component, based on a safety pop-out plate and a pop-out cylinder to limit the downward pressure of the piercing blade. The piercing blade presses down in the pressure hole of the safety pop-out plate, and the positioning block hole cooperates with the positioning hole to prevent damage when the piercing blade is not in place. If the operator's hand is in the downward pressure area of ​​the piercing blade, it will be popped out by the front side of the safety pop-out plate, effectively improving the safety performance and stability of the equipment. However, before using this type of piercing device, the operator needs to align multiple wires with the corresponding holes on the connector. Because the holes are relatively small and compact, tools such as tweezers are usually required to move the wires to the holes, resulting in a cumbersome overall operation during the alignment process, which affects the efficiency of connector assembly.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a piercing device for connector assembly. Summary of the Invention

[0005] The purpose of this invention is to provide a piercing device for connector assembly, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a piercing device for connector assembly, comprising a base and an alignment component. A support frame is mounted on the top of the base, and an electric cylinder is mounted on the top of the support frame. A lifting frame is connected to the bottom of the electric cylinder, and a pressure head is mounted at the center of the bottom of the lifting frame. A positioning seat is mounted at the center of the top of the base. The alignment component is mounted on the top of the base and includes an alignment seat, a slide rod, a compression spring, a slide block, a baffle, a guide sleeve, a partition, an inclined plate, and a pressure rod. The alignment seat is mounted on the top of the base, and slide rods are symmetrically fixed on one side of the alignment seat. A compression spring is sleeved on the outer side of the slide rod, and one end of the compression spring is connected to the slide block, with the slide block slidably connected to the slide rod. A baffle is fixed on the top of the slide block, and a guide sleeve is mounted on one end of the baffle. A partition is mounted inside the guide sleeve, and an inclined plate is fixed on the top of the baffle. A pressure rod is mounted on one end of the lifting frame.

[0007] Furthermore, the alignment seat is provided with a clamping assembly, which includes a light rod, a buffer spring and a sliding frame. The light rod is placed inside the alignment seat, and a buffer spring is sleeved on the outer side of one end of the light rod, and a sliding frame is connected to one end of the buffer spring.

[0008] Furthermore, the clamping assembly also includes a fixing post, a connecting plate, an electromagnet, and a touch button. The top two ends of the sliding frame are symmetrically arranged with fixing posts, and the top of the fixing posts is fixed with a connecting plate. An electromagnet is arranged in the center of the bottom of the connecting plate, and a touch button is provided on one side of the light rod.

[0009] Furthermore, the clamping assembly also includes a synchronizing plate, connecting rods, and clamping plates. The synchronizing plate is slidably connected to the outer side of the fixing column, and the four ends of the synchronizing plate are rotatably connected to the connecting rods. The top of the connecting rods is rotatably connected to the clamping plates, and the clamping plates are rotatably connected to the connecting plate.

[0010] Furthermore, the inclined plate has a moving component at its end and the bottom of the positioning seat. The moving component includes a guide block and a limiting groove. The inclined plate has a guide block at its end, and the guide block is fixedly connected to the slide. The top of the base has a limiting groove, and the top width of the limiting groove is smaller than the bottom width of the limiting groove.

[0011] Furthermore, the moving component also includes a slider and a return spring. The slider is slidably connected inside the limiting groove and is fixedly connected to the positioning seat. A return spring is provided on one side of the slider.

[0012] Furthermore, an auxiliary component is provided on one side of the upright frame. The auxiliary component includes a drive column, a drive plate, and a guide groove. A drive column is fixed on one side of the lifting frame, and a drive plate is slidably connected to one side of the upright frame. A guide groove is provided on one side of the drive plate, and the drive column is slidably connected to the drive plate through the guide groove.

[0013] Furthermore, the auxiliary component also includes a connecting seat, a spring seat, and a positioning plate. The connecting seat is fixed to the bottom of the drive plate, and a spring seat is disposed on one side of the connecting seat, with the positioning plate connected to the end of the spring seat.

[0014] Furthermore, the auxiliary component also includes a support block, a counterweight block, and a top plate. The lower end of the connecting seat is fixed with a support block, and a counterweight block is slidably connected to the top of one end of the support block. The top of the counterweight block is connected to the top plate.

[0015] Furthermore, the top plate is slidably connected to the positioning seat, and the middle side view of the positioning seat is U-shaped.

[0016] This invention provides a piercing device for connector assembly, which has the following advantages:

[0017] 1. In this invention, when the wire is placed into the hole on the connector, the electric cylinder is activated to move the lifting frame down a short distance. At this time, the pressure rod will press the inclined plate, aligning the two slots at the bottom of the guide sleeve with the two slots at the top of the alignment seat. Because the upper part of the guide sleeve is wider, it is convenient to insert the wire into it. After insertion, the wire will fall under the guide into the slot at the top of the alignment seat, thus quickly aligning the wire. Furthermore, the partition plate divides the interior of the guide sleeve, allowing two wires to be placed simultaneously, improving placement efficiency. After placement, as the electric cylinder continues to move the lifting frame down a short distance, the guide sleeve moves to the alignment seat. Above the other two slots on the seat, during this process, because the bottom end of the guide sleeve and the partition plate is inclined, the protruding part of the wire placed behind it can be pushed downwards during movement, so that it is completely placed in the groove, and the top of it is blocked by the baffle. At the same time, the inclined plate can also block the front of the pressure head, preventing personnel's hands from getting close to the pressure head, which also plays a certain protective role. After the wire and connector are assembled, when the electric cylinder drives the lifting frame to move upward, the pressure rod will separate from the inclined plate. At this time, the compression spring will push the slide, thereby automatically removing the baffle and guide sleeve from the top of the seat, so as to avoid blocking the wire and affecting the workpiece unloading operation.

[0018] 2. In this invention, after the baffle blocks the top of all the wires, as the pressure rod continues to move downward, it slides from the inclined plate onto the guide block. At this time, the movement direction of the alignment seat can be restricted by the limiting groove and the slider. Therefore, when the pressure rod presses against the guide block, it can drive the alignment seat to move towards the positioning seat, so that the end of the wire can fit against the middle side of the positioning seat. During this process, when part of the end of the wire fits against the positioning seat, the sliding frame can compress the buffer spring to buffer and avoid applying too much force to cause the end of the wire to bend. Thus, after the alignment seat moves, all the ends of the wires can be flush, further improving the quality of the assembly of the wires and connectors. When the pressure rod moves upward and separates from the guide block, the alignment seat and the sliding frame will automatically reset under the action of the return spring and the buffer spring, so that the work can be repeated.

[0019] 3. Before the positioning seat moves, the slide will contact the touch button, thereby automatically activating the electromagnet and causing it to attract the synchronization plate. The connecting rod will then push the electromagnet, causing it to rotate at the end of the connecting plate, thereby clamping the wire and improving the stability of the wire after placement. It also facilitates subsequent wire movement and alignment operations. After assembly, the compression spring will push the slide, causing the slide to separate from the touch button. At this time, because the magnetic force of the electromagnet disappears, the synchronization plate will move down under the action of gravity. At the same time, the connecting rod will pull the clamping plate, which will automatically release the wire, making it very convenient for subsequent part removal.

[0020] 4. In this invention, when the electric cylinder drives the lifting frame to move down a short distance, it also pushes the drive plate through the drive column and guide groove, causing it to slide on the side of the upright. This causes the connecting seat to move the support block. Since the support block does not block the bottom of the counterweight, the top plate will move down under gravity, avoiding blocking the groove of the positioning seat. This makes it easy to place the connector inside the groove of the positioning seat. As the lifting frame continues to move down, the connecting seat will push the positioning plate to squeeze the connector through the spring seat, making the connector fit tightly against the inside of the positioning seat, thus automatically positioning it and facilitating subsequent docking operations. After assembly, when the electric cylinder drives the lifting frame to move up, the positioning plate will release the connector first, and then the support block will push the counterweight to move up, causing the top plate to push the connector out of the groove of the positioning seat, avoiding damage to the connector's wiring by simply pulling the connector out with the wire.

Detailed Implementation

[0029] Please see Figures 1 to 7 The present invention provides a technical solution: a piercing device for connector assembly, comprising a base 1 and an alignment component 7. A support frame 2 is mounted on the top of the base 1, and an electric cylinder 3 is mounted on the top of the support frame 2. A lifting frame 4 is connected to the bottom of the electric cylinder 3, and a pressure head 5 is mounted at the center of the bottom of the lifting frame 4. A positioning seat 6 is mounted at the center of the top of the base 1. The alignment component 7 is mounted on the top of the base 1 and includes an alignment seat 701, a sliding rod 702, a compression spring 703, a sliding block 704, a baffle 705, a guide sleeve 706, a partition 707, an inclined plate 708, and a pressure rod. 709, a positioning seat 701 is installed on the top of the base 1, and a slide rod 702 is symmetrically fixed on one side of the positioning seat 701. A compression spring 703 is sleeved on the outside of the slide rod 702, and one end of the compression spring 703 is connected to a slide block 704. The slide block 704 is slidably connected to the slide rod 702. A baffle 705 is fixed on the top of the slide block 704, and a guide sleeve 706 is installed on one end of the baffle 705. A partition 707 is provided inside the guide sleeve 706. An inclined plate 708 is fixed on the top of the baffle 705. A pressure rod 709 is installed on one end of the lifting frame 4.

[0030] Please see Figures 1 to 5A clamping assembly 8 is provided inside the positioning base 701. The clamping assembly 8 includes a guide rod 801, a buffer spring 802, and a sliding frame 803. The guide rod 801 is placed inside the positioning base 701, and the buffer spring 802 is sleeved on the outer side of one end of the guide rod 801. The sliding frame 803 is connected to one end of the buffer spring 802. The clamping assembly 8 also includes a fixing post 804, a connecting plate 805, an electromagnet 806, and a tactile button 807. The fixing posts 804 are symmetrically arranged at both ends of the top of the sliding frame 803. A connecting plate 805 is fixed to the top of the fixed column 804, and an electromagnet 806 is placed in the center of the bottom of the connecting plate 805. A touch button 807 is provided on one side of the light rod 801. The clamping assembly 8 also includes a synchronization plate 808, a connecting rod 809 and a clamping plate 810. The synchronization plate 808 is slidably connected to the outside of the fixed column 804, and the four ends of the synchronization plate 808 are rotatably connected to the connecting rod 809. The top of the connecting rod 809 is rotatably connected to the clamping plate 810, and the clamping plate 810 is rotatably connected to the connecting plate 805.

[0031] The specific operation is as follows: the electric cylinder 3 drives the lifting frame 4 to move down a short distance, and the pressure rod 709 will squeeze the inclined plate 708, so that the two slots at the bottom of the guide sleeve 706 are aligned with the two slots at the top of the alignment seat 701. Since the upper part of the guide sleeve 706 is wider, it is convenient to insert the wire into it. After insertion, the wire will slide down into the slot at the top of the alignment seat 701, thus enabling quick alignment of the wire. Furthermore, by using the partition 707 to divide the interior of the guide sleeve 706, two wires can be placed simultaneously. The wire is placed more efficiently, and as the electric cylinder 3 continues to drive the lifting frame 4 to move down a short distance, the guide sleeve 706 can move above the other two slots on the alignment seat 701. During this process, since the bottom end of the guide sleeve 706 and the partition plate 707 are inclined, the protruding part of the placed wire can be pushed downwards during the movement, so that it is completely placed in the groove, and the top is blocked by the baffle plate 705. After the baffle plate 705 blocks the top of all the wires, the slide 7... 04 will contact the touch button 807, thereby automatically activating the electromagnet 806, causing it to attract the synchronization plate 808. This will then drive the electromagnet 806 via the connecting rod 809, causing it to rotate at the end of the connecting plate 805, thus clamping the wire and improving its stability after placement. This also facilitates subsequent wire movement and alignment operations. Afterwards, the pressure head 5 will press the wire end into the connector, piercing the connection. Subsequently, the electric cylinder 3 will drive the lifting frame 4 upwards. When the pressure rod 709 separates from the inclined plate 708... The compression spring 703 pushes the slide 704, thereby automatically removing the baffle 705 and guide sleeve 706 from the top of the alignment seat 701 to avoid obstructing the wire and affecting the workpiece unloading operation. During this process, the compression spring 703 pushes the slide 704, causing the slide 704 to separate from the touch button 807. At this time, because the magnetic force of the electromagnet 806 disappears, the synchronization plate 808 will move down under the action of gravity. At the same time, the clamping plate 810 is pulled by the connecting rod 809, which can automatically release the wire, making it very convenient to pick up the part later.

[0032] Please see Figure 2 , Figure 3 , Figure 6 and Figure 7A moving component 9 is provided at the end of the inclined plate 708 and the bottom of the alignment seat 701. The moving component 9 includes a guide block 901 and a limiting groove 902. The guide block 901 is provided at the end of the inclined plate 708 and is fixedly connected to the slide 704. The top of the base 1 has a limiting groove 902, and the top width of the limiting groove 902 is smaller than the bottom width of the limiting groove 902. The moving component 9 also includes a slider 903 and a return spring 904. The slider 903 is slidably connected inside the limiting groove 902 and is fixedly connected to the alignment seat 701. A return spring 904 is provided on one side of the slider 903. An auxiliary component 10 is provided on one side of the upright 2. The auxiliary component 10 includes a drive column 1001, a drive plate 1002 and a guide groove 1003. The drive column 1001 is fixed on one side of the lifting frame 4, and the drive plate 1002 is slidably connected on one side of the upright 2. The drive plate 1002 has a guide groove 1003 on one side, and the drive column 1001 is slidably connected to the drive plate 1002 through the guide groove 1003. The auxiliary component 10 also includes a connecting seat 1004, a spring seat 1005 and a positioning plate 1006. The bottom of the drive plate 1002 is fixed with the connecting seat 1004, and a spring seat 1005 is placed on one side of the connecting seat 1004. The end of the spring seat 1005 is connected to the positioning plate 1006. The auxiliary component 10 also includes a support block 1007, a counterweight block 1008 and a top plate 1009. The lower end of the connecting seat 1004 is fixed with the support block 1007, and the top of one end of the support block 1007 is slidably connected to the counterweight block 1008. The top of the counterweight block 1008 is connected to the top plate 1009. The top plate 1009 is slidably connected to the positioning seat 6, and the middle side view of the positioning seat 6 is U-shaped.

[0033] The specific operation is as follows: When the electric cylinder 3 drives the lifting frame 4 to move down a short distance, the drive column 1001 will slide in the guide groove 1003, thereby driving the drive plate 1002 to slide on the upright frame 2. This allows the connecting seat 1004 to drive the support block 1007 to move. At this time, since the support block 1007 will not block the bottom of the counterweight block 1008, the top plate 1009 will move down under the action of gravity, avoiding blocking the groove of the positioning seat 6, thus facilitating the placement of the connector inside the groove of the positioning seat 6. Afterwards, as... As the lifting frame 4 continues to move downwards, the connecting seat 1004, through the spring seat 1005, drives the positioning plate 1006 to press the connector, making the connector tightly adhere to one side of the inner side of the positioning seat 6. This automatically positions the connector, facilitating subsequent docking operations. Furthermore, once the baffle 705 covers the top of all the wires, as the pressure rod 709 continues to move downwards, it slides from the inclined plate 708 onto the guide block 901. At this point, the limiting groove 902 and the slider 903 restrict the movement direction of the positioning seat 701. Therefore, during the pressing... When rod 709 presses against guide block 901, it moves alignment seat 701 towards positioning seat 6, allowing the wire end to fit against the middle side of positioning seat 6. During this process, when part of the wire end fits against positioning seat 6, sliding frame 803 compresses buffer spring 802 to buffer the wire end and prevent excessive force from bending it. This ensures that all wire ends are flush after alignment seat 701 moves, further improving the quality of wire and connector assembly. Meanwhile, in the electric cylinder... 3. The lifting frame 4 is moved upward, and after the pressure rod 709 is separated from the guide block 901, the positioning seat 701 and the sliding frame 803 will automatically reset under the action of the reset spring 904 and the buffer spring 802. During the upward movement of the lifting frame 4, the positioning plate 1006 will release the connector first, and then the support block 1007 will squeeze the counterweight block 1008 to move upward, so that the top plate 1009 will push the connector out of the groove of the positioning seat 6, avoiding damage to the connector's wiring by pulling the connector out with just the wire.

[0034] In summary, this piercing device for connector assembly works as follows: First, the electric cylinder 3 moves the lifting frame 4 down a short distance, causing the drive column 1001 to slide within the guide groove 1003. This causes the drive plate 1002 to slide on the upright frame 2, which in turn moves the support block 1007 via the connecting seat 1004. The top plate 1009 then moves down under gravity, facilitating the placement of the connector into the groove of the positioning seat 6. Next, as the lifting frame 4 continues to move down, the connecting seat 1004, via the spring seat 1005, causes the positioning plate 1006 to press against the connector, ensuring the connector is tightly against the inner side of the positioning seat 6, thus automatically positioning it. Furthermore, the pressure rod 709 presses against the inclined plate 708, causing the two slots at the bottom of the guide sleeve 706 to align. The two slots on the upper part of the seat 701 are aligned, and because the upper part of the guide sleeve 706 is relatively wide, it is convenient to insert the wire into it. After insertion, the wire will slide down into the slot at the top of the aligning seat 701 under its guide. The partition 707 is used to divide the inside of the guide sleeve 706, so that two wires can be placed at the same time, improving the efficiency of wire placement. Then, as the electric cylinder 3 continues to drive the lifting frame 4 to move down a short distance, the guide sleeve 706 can be moved above the other two slots on the aligning seat 701. During this process, because the bottom end of the guide sleeve 706 and the partition 707 are inclined, the protruding part of the placed wire can be pushed down during the movement, so that it is completely placed in the groove. Then, when the baffle 705 aligns with the guide sleeve 706, the wire will be placed in the groove. After all the wires are covered at the top, the slide block 704 will contact the touch button 807, thereby automatically activating the electromagnet 806, causing it to attract the synchronization plate 808. This will then push the electromagnet 806 via the connecting rod 809, causing it to rotate at the end of the connecting plate 805, thus clamping the wires. Simultaneously, as the pressure rod 709 continues to move downwards, it will slide from the inclined plate 708 onto the guide block 901. At this point, the limiting groove 902 and the slider 903 restrict the movement direction of the alignment seat 701. Therefore, when the pressure rod 709 presses against the guide block 901, it can drive the alignment seat 701 to move towards the positioning seat 6, allowing the wire end to fit against the middle side of the positioning seat 6. During this process, when part of the wire end fits against the positioning seat 6, the sliding frame 803 can... The compression spring 802 provides cushioning, ensuring all wire ends are flush after the alignment seat 701 moves. Then, the pressure head 5 presses the wire ends into the connector, piercing the connection. Finally, the electric cylinder 3 moves the lifting frame 4 upwards. When the pressure rod 709 separates from the guide block 901, the alignment seat 701 and sliding frame 803 automatically reset under the action of the return spring 904 and the cushioning spring 802. When the pressure rod 709 separates from the inclined plate 708, the compression spring 703 pushes the slide 704, automatically removing the baffle 705 and guide sleeve 706 from the top of the alignment seat 701. During this process, the compression spring 703 pushes the slide 704, causing it to separate from the touch button 807.At this point, as the magnetism of electromagnet 806 disappears, synchronization plate 808 will move downwards under gravity. Simultaneously, connecting rod 809 pulls clamping plate 810, automatically releasing the wire. Similarly, as lifting frame 4 moves upwards, positioning plate 1006 will first release the connector, then support block 1007 will press counterweight block 1008 upwards, causing top plate 1009 to push the connector out of the groove in positioning seat 6, facilitating workpiece unloading.
