Description

Technical Field

[0001] This application relates to the field of automated manufacturing technology, and in particular to a crimping device for connector pins. Background Technology

[0002] Connectors are indispensable in the manufacturing, use, and connection of electronic components in electronic products. There are two main ways to connect connectors to PCBs: soldering and crimping. Soldering involves directly connecting the connector pins to the pads on the PCB using solder. However, this process can result in open circuits or poor solder joints, which is detrimental to manufacturing and makes disassembly and repair difficult. Crimping, on the other hand, uses mechanical pressure to connect the connector pins to holes or slots on the PCB. Traditional crimping typically requires specialized equipment and tools, leading to higher equipment and tool costs and hindering rapid product production. Utility Model Content

[0003] In view of this, this application provides a crimping device for connector pins, which ensures precise positioning between the connector and the PCB board through the cavity and positioning post provided on the carrier, and bends the connector pins through a pressure device. The specific technical solution is as follows:

[0004] A crimping device for connector pins includes a carrier having at least one cavity for positioning and accommodating the connector, and a positioning post for positioning a PCB board. Through the cooperation of the cavity and the positioning post, the pins on the connector can be accurately inserted into the corresponding connection holes on the PCB board. A pressure device is used to apply pressure to the pins passing through the connection holes to bend them.

[0005] Preferably, the orientation of the pins is perpendicular or parallel to the pressure application direction of the pressurizing device.

[0006] More preferably, the orientation of the pins is perpendicular to the pressure direction of the pressurizing device, and the pins are directly bent by the pressurizing device to fit the PCB board.

[0007] In a further preferred embodiment, the pressurizing device includes a pressure block, which has a bending gap between itself and the PCB board, and is driven by a displacement component to apply pressure to the pins.

[0008] Preferably, the displacement component is one of a linear actuator, a helical mechanism, a linear guide, and a cylinder.

[0009] Preferably, the pins are positioned parallel to the pressure direction of the pressurizing device.

[0010] More preferably, the pressurizing device includes a pressure block and a displacement assembly, wherein the surface of the pressure block used to press the pin is inclined, and the displacement assembly is fixedly connected to a connecting block used to adjust the angle of the pressure block.

[0011] Preferably, the pressure block has an arc surface that allows it to rotate relative to the connecting block.

[0012] Preferably, the pressurizing device is further provided with a distance sensor or pressure sensor for feedback of the applied pressure, so as to accurately control the pressure during the crimping process of the pin.

[0013] More preferably, the distance sensor is a laser rangefinder, an ultrasonic sensor, or a proximity switch.

[0014] The beneficial effects of this application are:

[0015] The cavities and positioning posts on the carrier ensure precise positioning between the connector and the PCB board, ensuring that the pins are accurately inserted into the corresponding connection holes, thus improving assembly efficiency.

[0016] Depending on the pin orientation and the pressure direction of the pressurizing device, this device can flexibly select vertical or parallel bending methods to meet the pin crimping requirements under different process conditions, and has a high degree of adaptability and flexibility.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Combination Figures 1-4 The crimping device for connector pins described in this application is further described below. It includes a carrier 1, which has at least one cavity 11 for positioning and accommodating connector 2, and a positioning post 12 for positioning PCB board 3. Through the cooperation of the cavity 11 and the positioning post 12, the pins 21 on connector 2 can be accurately inserted into the corresponding connection holes on PCB board 3. The pressing device 4 applies pressure to the pins 21 passing through the connection holes to bend them, so as to ensure a firm connection between the pins 21 and the connection holes.

[0024] The orientation of the pin 21 can be perpendicular or parallel to the pressure application direction of the pressurizing device 4. It should be noted that the orientation of the pin 21 is the direction it faces after passing through the connection hole and before being crimped.

[0025] like Figure 1 As shown, when the orientation of the pin 21 is perpendicular to the pressure direction of the pressurizing device 4, the pin 21 is directly bent by the pressurizing device 4 to fit the PCB board 3. Specifically, the pressurizing device 4 includes a pressure block 41, and a bending gap is provided between the pressure block 41 and the PCB board 3 to avoid damage to the pin 21 or the PCB board 3 due to instantaneous impact during bending. At the same time, precise control of the bending gap can improve the accuracy and consistency of the bending of the pin 21, and the displacement component 42 drives it to apply pressure to the pin 21. The displacement component can be a linear actuator, a screw mechanism, a linear guide, or a cylinder, etc.

[0026] like Figure 2 As shown, when the orientation of the pin 21 is parallel to the pressure direction of the pressurizing device 4, the pressurizing device 4 includes a pressure block 41 and a displacement assembly 42. The surface of the pressure block 41 used to press the pin 21 is inclined, and the displacement assembly 42 is fixedly connected to a connecting block 43 for adjusting the angle of the pressure block 41. The displacement assembly can be a linear actuator, a screw mechanism, a linear guide rail, or a cylinder, etc.

[0027] like Figure 3 As shown, the connecting block 43 and the pressing block 41 are tangentially fitted, and the pressing block 41 has an arc surface that allows it to rotate relative to the connecting block 43. By engaging the arc surface on the connecting block 43 with the arc surface on the pressing block 41, the pressing block 41 will rotate relative to the connecting block 43 until the inclined surface of the pressing block is parallel to the PCB board 3, thereby completing the bending of the pin 21.

[0028] The pressurizing device 4 may also be equipped with a distance sensor or pressure sensor for feedback of the applied pressure, so as to accurately control the pressure during the crimping process of the pin 21 and ensure product consistency. The distance sensor may be a laser rangefinder, an ultrasonic sensor, or a proximity switch, etc.
