Description

Technical Field

[0001] The present application relates to the field of cable installation, and in particular to a cable terminal fastening mechanism. Background Art

[0002] Cables are wires and signal transmission lines that can be used to transmit analog and digital signals and are suitable for a variety of applications. Currently, with the continuous updates and iterations of mobile phones, the requirements for signal transmission are getting higher and higher, which has led to the gradual application of cables in the mobile phone field.

[0003] Currently, when cables are applied to mobile phones, connection terminals are usually set at both ends of the cable. During the production and assembly process of the mobile phone, the connection terminals at the ends of the cable are usually manually fastened to the mother socket of the mobile phone's PCB board using auxiliary tools, and the cable is pressed into the cable installation groove reserved in the mobile phone case, thereby achieving the installation of the cable on the mobile phone.

[0004] However, this manual installation method is usually inefficient, which may result in poor cable installation results. Utility Model Content

[0005] In order to improve the installation effect of cables, the present application provides a cable terminal fastening mechanism.

[0006] This application provides a cable terminal fastening mechanism, which adopts the following technical solutions:

[0007] A cable terminal fastening mechanism includes a mounting seat, a lifting assembly and a grabbing assembly. The lifting assembly includes a power piece and a lifting slider. The power piece and the lifting slider are both mounted on the mounting seat, and the lifting slider is connected to the power piece. The power piece is used to drive the lifting slider to move in a vertical direction. The grabbing assembly is mounted on the lifting slider, and the grabbing assembly is used to grab the terminal of the cable.

[0008] By adopting the above technical solution, when fastening the terminal of the cable, the grabbing assembly is used to grab the terminal of the cable, and then the power part in the lifting assembly drives the lifting slider to descend, so that the lifting slider drives the grabbing assembly to descend, and the grabbing assembly gradually drives the terminal of the cable to be fastened to the PCB board mother seat, thereby replacing the manual cable fastening method with the mechanical cable fastening method, thereby facilitating the improvement of cable installation efficiency and facilitating the purpose of improving the cable installation effect.

[0009] In a specific feasible implementation scheme, the power component includes a lifting motor, a lifting screw and a linear guide rail, the linear guide rail is installed on a mounting seat, the lifting slider is slidably installed on the linear guide rail, the lifting motor is installed on the mounting seat, one end of the lifting screw rod is connected to the output shaft of the lifting motor, and the other end is connected to the lifting slider.

[0010] By adopting the above technical solution, when a lifting action is required, the lifting motor drives the lifting screw to move, so that the lifting screw drives the lifting slider to move up and down along the linear guide rail, thereby driving the grabbing assembly installed on the lifting slider to move in the vertical direction, thereby driving the cable terminal to move in the vertical direction, so that the cable terminal can be buckled onto the PBC board mother seat, thereby improving the cable installation efficiency.

[0011] In a specific possible implementation scheme, it also includes a data monitoring component, which includes a pressure sensor and a sensing spring. The pressure sensor is installed on the lifting component, and the grasping component is connected to the pressure sensor through a connecting piece. The sensing spring is installed on the grasping component, and the sensing spring is also connected to the lifting component through a connecting piece.

[0012] By adopting the above technical solution, when the lifting assembly drives the grabbing assembly to descend to the PCB board mother seat, the terminal of the cable gradually contacts the PCB board mother seat, so that the descent of the grabbing assembly is resisted, causing the lifting assembly to gradually compress the sensing spring through the connecting piece, so that the elastic force generated by the sensing spring can be detected by the pressure sensor, and the detected value is transmitted to the control system, so that the control system can send instructions to the lifting motor according to the measured pressure value, thereby controlling the start and stop of the lifting assembly, so as to facilitate the precise installation of the cable terminal.

[0013] In a specific possible implementation scheme, the connecting member includes a pressure block and a connecting rod, both of which are installed on the lifting assembly, and the pressure block is connected to one end of the connecting rod, the pressure block is connected to the grasping assembly, and the pressure block is also connected to the sensing spring.

[0014] By adopting the above technical solution, when the lifting assembly drives the grabbing assembly to descend, the grabbing assembly pushes the lifting slider down through the pressure block and the sensor spring, and by shortening the distance between the pressure block and the lifting slider, the sensor spring is compressed, so that the pressure sensor can monitor the pressure value generated by the grabbing assembly when installing the cable terminal, thereby facilitating the improvement of the cable installation accuracy.

[0015] In a specific possible implementation scheme, the data monitoring component also includes a magnetic scale and a read head, the magnetic scale is vertically mounted on the side wall of the mounting base, the read head is mounted on the lifting component, and the read head is used to read data from the magnetic scale.

[0016] By adopting the above technical solution, during the installation of the cable terminal, the lifting assembly can drive the reading head to descend along the magnetic scale while making a descending movement, so that the value on the magnetic scale can be read and transmitted to the external control system, thereby facilitating real-time monitoring of the status of the cable terminal during the installation process, thereby facilitating improving the accuracy of cable installation.

[0017] In a specific possible implementation scheme, the data monitoring component also includes a first sensor, a second sensor and a baffle, the first sensor and the second sensor are both mounted on the side wall of the mounting base, and the first sensor is located above the second sensor, the baffle is mounted on the lifting component, and the baffle is used to block the signal of the first sensor or the second sensor.

[0018] By adopting the above technical solution, by setting the first sensor and the second sensor, it is possible to ensure that the lifting slider can move within the set range when the lifting slider is lifting. If it exceeds the set range, an instruction will be sent to the control system through the first sensor or the second sensor, so that the control system sends an instruction to the lifting motor to stop working, thereby facilitating the cable to protect the lifting motor.

[0019] In a specific possible implementation scheme, the grabbing assembly includes a vacuum suction head, which is installed on the lifting assembly and is used to be connected to an external air source and to absorb the terminal of the cable.

[0020] By adopting the above technical solution, when it is necessary to grab the terminal of the cable, the vacuum suction head is driven down to the terminal of the cable by the lifting assembly, and the terminal of the cable is adsorbed by the vacuum suction head, thereby facilitating the subsequent fastening of the cable to the PCB socket.

[0021] In a specific feasible implementation scheme, a reset member is also installed on the grabbing assembly, and the reset member includes a reset torsion spring, and the reset torsion spring is installed on the grabbing assembly. The grabbing assembly is also provided with a holder, and the holder is provided with at least two blocks, and a gap is left between at least two of the blocks. One end of the reset torsion spring is inserted into the gap between the at least two blocks, and the other end of the reset torsion spring is connected to the lifting assembly.

[0022] By adopting the above technical solution, after the grabbing assembly grabs the cable terminal, the shape of the cable needs to be further adjusted to adapt to the shape of the cable installation slot in the mobile phone case. At this time, the cable terminal will deflect at a certain angle, which will drive the grabbing assembly to deflect, thereby applying force to the reset torsion spring. After the cable terminal is installed, the grabbing assembly can be reset under the action of the reset torsion spring, thereby facilitating continuous adsorption of the cable terminal.

[0023] In a specific embodiment, the gripping assembly further includes a vacuum rod, which is mounted on the lifting assembly. The interior of the vacuum rod is hollow and connected to a vacuum suction head, and the vacuum rod is used to connect the vacuum suction head to an external air source.

[0024] By adopting the above technical solution, a vacuum rod is provided to be connected to the vacuum suction head, thereby increasing the descending height of the vacuum suction head, thereby facilitating the installation of cables.

[0025] In a specific embodiment, a rotary joint is installed on the vacuum suction head, and the rotary joint is used to connect the vacuum suction head to an external air source.

[0026] By adopting the above technical solution, the external air source is connected to the vacuum suction head through the rotary joint, and the rotary joint is not affected by the rotation of the vacuum suction head, so that the connection between the vacuum suction head and the external air source is always maintained, thereby facilitating the vacuum suction head to adsorb the terminal of the cable, thereby conveying the cable.

[0027] In summary, this application has at least one of the following beneficial effects:

[0028] 1. This application sets up a lifting component and a grabbing component to achieve mechanical transportation of cables and installation of cable terminals on the PCB motherboard, thereby replacing traditional manual installation and improving cable installation efficiency.

[0038] The present application discloses a cable terminal fastening mechanism, referring to Figure 1 and Figure 2 , including a mounting base 1, a lifting component 2, a grabbing component 3 and a data monitoring component 4.

[0039] Reference Figure 1 and Figure 2The lifting assembly 2 includes a power part and a lifting slider 25. The power part includes a lifting motor 21, a lifting screw 22 and a linear guide 23. The lifting motor 21 is fixedly mounted on the side wall of the upper end of the mounting base 1. The lifting motor 21 adopts a screw motor. The linear guide 23 is fixedly mounted on the side wall of the mounting base 1 in the vertical direction, and the linear guide 23 is located below the lifting motor 21. The lifting screw 22 is mounted on the lifting motor 21 in the vertical direction. The lifting screw 22 is connected to the output end of the lifting motor 21. The lifting motor 21 and the way in which the lifting motor 21 drives the lifting screw 22 to move are both existing technologies in this field and will not be elaborated here. The lower end of the lifting screw 22 extends downward to the linear guide 23, and the lower section of the lifting screw 22 is fixedly mounted with a guide rod 24 in the vertical direction. The lifting slider 25 is slidably mounted on the linear guide 23 in the vertical direction. The guide rod 24 and the lifting slider 25 are both connected to the data monitoring assembly 4. In some other embodiments of the present application, the lifting motor 21 and the lifting screw 22 may be replaced by a cylinder, the piston rod of which is connected to the data monitoring component 4; or the lifting motor 21 and the lifting screw 22 may be replaced by a voice coil motor, the output end of which is connected to the data monitoring component 4; or the lifting motor 21 and the lifting screw 22 may be replaced by a cam mechanism, the follower of which is connected to the monitoring component 4. Furthermore, the linear guide rail 23 used to achieve lifting and lowering limits may be replaced by a dovetail groove or a bushing.

[0040] Reference Figure 2 and Figure 3 The grabbing assembly 3 includes a vacuum rod 31 and a vacuum suction head 32.

The vacuum rod 31 is a tubular rod with a hollow interior, and a rotary joint 33 is fixedly mounted on the upper end of the vacuum rod 31. The rotary joint 33 is used to connect to an external air source. A magnet 34 is fixedly mounted on the lower end of the vacuum rod 31. The magnet 34 is annular. The vacuum suction head 32 is sleeved on the lower end of the vacuum rod 31, and the vacuum suction head 32 is connected to the inside of the vacuum rod 31. The vacuum suction head 32 is used to adsorb the terminals of the cable. A metal ring 35 for adsorbing with the magnet 34 is fixedly mounted on the top wall of the vacuum suction head 32. A positioning hook 36 is also fixedly mounted on the lower end of the vacuum rod 31. The positioning hook 36 is located above the magnet 34. The positioning hook 36 is used to engage with the metal ring 35. Refer to Figure 4 In another embodiment of the present application, a suction guide nozzle 37 is slidably installed in the vacuum suction head 32. The suction guide nozzle 37 is hollow inside and connected to the vacuum rod 31. When the terminal of the cable is adsorbed, the external air source draws air to the vacuum suction head 32 through the vacuum rod 31, thereby sucking the suction guide nozzle 37 toward the vacuum rod 31, so that the air in the vacuum suction head 32 is extracted from the suction guide nozzle 37, thereby accelerating the flow rate of the air in the vacuum suction head 32, thereby facilitating improving the adsorption effect of the cable terminal.

[0041] In some other embodiments of the present application, the grabbing assembly 3 may be a clamping cylinder, which clamps the terminal of the cable through the clamping cylinder.

[0042] Reference Figure 1 and Figure 2 The connecting member 5 includes a pressure block 51, a connecting rod 52, a bearing 53 and a limit plate 55. The vacuum rod 31 is rotatably mounted on the lifting slider 35 through the bearing 53. The limit plate 55 is coaxially mounted on the vacuum rod 31, and the limit plate 55 is located above the bearing 53. The connecting rod 52 is slidably mounted on the top wall of the lifting slider 25 along the vertical direction. The pressure block 51 is fixedly mounted on the top wall of the connecting rod 52, and a bushing 56 is fixedly mounted on the bottom wall of the pressure block 51. The bushing 56 is coaxially arranged with the vacuum rod 31, and the bushing 56 is slidably connected to the vacuum rod 31.

[0043] Reference Figure 1 and Figure 2 The data monitoring component 4 includes a pressure sensor 41, a sensing spring 42, a magnetic scale 43 and a reading head 44. One end of the pressure sensor 41 is fixedly connected to the lower end of the guide rod 24, and the other end is fixedly connected to the top wall of the pressure block 51.

[0044] Reference Figure 1 and Figure 4 The sensing spring 42 is mounted on the vacuum rod 31, and one end of the sensing spring 42 contacts the top wall of the limit plate 55, and the other end contacts the bottom wall of the bushing 56. The pressure sensor 41 is used to detect the pressure value of the sensing spring 42 and transmit it to the control system. Figure 1 and Figure 5 , the magnetic scale 43 is fixedly mounted on the side wall of the mounting base 1 in the vertical direction, and the reader 44 is fixedly mounted on the side wall of the lifting slider 25 near the magnetic scale 43, with a gap left between the reader 44 and the magnetic scale 43. The reader 44 is used to read the data of the magnetic scale 43 and transmit the data information to the external control system. The value read by the reader 44 is the displacement value of the lifting slider 25. The external control system is a prior art and will not be elaborated here. In some other embodiments of the present application, the component used to measure the displacement of the lifting slider 25 is not limited to the magnetic scale 43, but can also be a grating scale, a contact displacement sensor, or a laser displacement sensor.

[0045] Reference Figure 1 and Figure 3A reset part is also installed on the vacuum rod 31, and the reset part includes a reset torsion spring 6. An abutment groove 251 is opened in the vertical direction on the side wall of the lifting slider 25 below the limit plate 55. A clamping seat 7 is fixedly installed on the vacuum rod 31 near the abutment groove 251. Two clamping blocks 71 are fixedly installed on the clamping seat 7, and a gap is left between the two clamping blocks 71. The reset torsion spring 6 is installed on the vacuum rod 31, and one end of the reset torsion spring 6 extends to the gap between the two clamping blocks 71, and the other end extends into the abutment groove 251. After the terminal of the cable is adsorbed, the shape of the cable will be adjusted to adapt to the shape of the cable installation slot in the mobile phone case. When the shape of the cable is adjusted, the terminal of the cable will be deflected to a certain extent, which will drive the vacuum suction head 32 to rotate a certain angle, so that the vacuum suction head 32 drives the vacuum rod 31 to rotate through the positioning hook, and the vacuum rod 31 drives the base 7 to rotate, so that the base 7 drives one end of the reset torsion spring 6 to rotate around the vacuum rod 31 through the clamping block 71, thereby causing the reset torsion spring 6 to produce a certain twist, and after the cable is installed, the reset torsion spring 6 drives the base 7 to rotate and reset, thereby driving the vacuum rod 31 and the vacuum suction head 32 to rotate and reset, so that the vacuum suction head 32 can adsorb the terminal of the new cable.

[0046] Reference Figure 1 The data monitoring assembly 4 also includes a first sensor 46, a second sensor 47, and a baffle 48. The first sensor 46 and the second sensor 47 are fixedly mounted on the side wall of the mounting base 1 along a vertical line, and the first sensor 46 and the second sensor 47 are both located above the magnetic scale 43, and the second sensor 47 is located between the first sensor 46 and the magnetic scale 43. The distance between the first sensor 46 and the second sensor 47 is the maximum distance that the lifting slider 25 can move. The first sensor 46 and the second sensor 47 are both photoelectric sensors and are used to transmit signals to the external control system. Photoelectric sensors are existing technology and will not be described in detail here. The baffle 48 is fixedly mounted on the side wall of the lifting slider 25 near the first sensor 46 and the second sensor 47, and the baffle 48 extends to the vertical plane where the first sensor 46 and the second sensor 47 are located, and the baffle 48 is used to block the photoelectric signals of the first sensor 46 and the second sensor 47. By providing the first sensor 46 and the second sensor 47 , when the lifting slider 25 drives the blocking piece 48 to move to block the photoelectric signal of the first sensor 46 or the second sensor 47 , the lifting motor 21 stops working, thereby protecting the lifting motor 21 .

[0047] The working principle of the embodiment of the present application is as follows: when the cable is conveyed to the fastening mechanism, the terminal of the cable is sucked by the vacuum suction head 32, and the fastening mechanism is moved above the PCB socket. Then, after adjusting the shape of the cable, the lifting motor 21 drives the lifting screw rod 22 to descend, thereby driving the guide rod 24 to descend, so that the guide rod 24 drives the pressure block 51 to descend through the pressure sensor 41, so that the pressure block 51 pushes the limit plate 55 downward through the sensor spring 42, thereby driving the lifting slider 25 to move downward, thereby driving the vacuum rod 31 to move downward, so that the vacuum suction head 32 drives the terminal of the cable to gradually move downward.

[0048] When the terminal of the cable contacts the PCB socket, the vacuum suction head 32 is subjected to resistance, so that the descent of the vacuum rod 31 is also subjected to resistance and slowed down, and the lifting motor 21 continues to operate, thereby driving the lifting screw 22 to continue to descend, so that the lifting screw 22 drives the pressure block 51 through the guide rod 24 to continue to approach the lifting slider 25, thereby compressing the sensing spring 42, so that the elastic force generated by the sensing spring 42 is transmitted to the pressure block 51, so that the pressure block 51 generates a force on the pressure sensor 41, so that the force can be captured by the pressure sensor 41, and the pressure sensor 41 transmits the detected pressure value of the sensing spring 42 to the control system. At the same time, as the lifting slider 25 descends, the reading head 44 also continuously reads the value on the magnetic scale 43 and transmits it to the control system. When the control system determines that the pressure value and the displacement value are both within the normal range set by the system, the control system sends a control instruction to the lifting motor 21 to make the lifting motor 21 continue to work, thereby driving the lifting screw rod 22 to continue to descend, so that the pressure block 51 continues to descend, and drives the vacuum rod 31 and the lifting slider 25 to continue to descend through the sensing spring 42, so that the vacuum suction head 32 on the vacuum rod 31 drives the terminal of the cable to continue to move downward, thereby continuing to press the terminal of the cable down on the PCB socket.

[0049] When fastening the cable terminal to the PCB mother socket, the pressure block 51 drives the vacuum rod 31 downward via the sensor spring 42, causing the vacuum head 32 on the vacuum rod 31 to fasten the cable terminal to the PCB. At this time, the control system detects whether the pressure value and displacement value are within the set normal range. If the pressure value detected by the control system reaches the system's set value, the control system determines that the cable terminal is fastened and sends a stop command to the lifting motor 21, at which point the fastening operation is completed. If, during the process of fastening the cable terminal, and before the baffle 48 descends to the second sensor 47, the pressure value received by the control system exceeds the set normal value range, or the displacement value does not meet the standard, the control system sends a stop command to the lifting motor 21 and determines that the cable terminal has failed to fasten.

[0050] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
