[0002] The stringing of nut parts on notebook hinge components has been one of the problems in notebook assembly production lines. The nut parts of notebook hinge components are very small, and the thickness is much larger than the diameter. The nut parts need to be distinguished in terms of positive and negative directions during stringing. In the past, the stringing was manually performed, which was difficult, time-consuming, labor-intensive, and low in efficiency. In addition, due to the large thickness of the nut, the thickness is much larger than the diameter. Once the nut is slightly deflected during stringing, the part is easily hung on the top of the stringing rod, resulting in blockage of the entire stringing rod.

[0024] The notebook hinge nut stringing device of this embodiment includes a conveying device 10 and a stringing device 20. The stringing device includes a stringing rod 21 and an attitude control component. The conveying device is used to store nuts and convey each nut to the stringing device in a single row according to a set attitude, and string them on the stringing rod. The attitude control component is located at the upper end of the stringing rod to control the attitude of the nuts to prevent the nuts from deflecting when they are stringed on the stringing rod. "Single row" means that each nut is arranged one by one in a row. Figures 1 to 5 As shown, nut 40 is a hexagonal nut that can be used in laptop hinges. This nut is relatively small, and its thickness-to-diameter ratio is large. The inner hole of the nut serves as the through hole for mating with the feed rod. Figure 1 As shown, the material feeding device also includes a mounting base plate 50, on which a support frame 28 is fixedly connected. The feeding rod 21 is mounted on the base plate. The attitude control component can be a shield or a support, used to limit the deflection of the nut when it is fed onto the feeding rod, preventing the nut from getting caught on the feeding rod. This structure facilitates feeding the fixed nuts in the laptop hinge components onto the corresponding feeding rods according to the feeding requirements. The feeding process is simple and efficient, which is convenient for subsequent assembly production. At the same time, it improves the blockage caused by the nut getting caught on the feeding rod, further improving the feeding efficiency and reducing labor costs, which helps to speed up the production cycle.

[0025] In this embodiment, the attitude control component includes at least a pair of control arms 22 for clamping the upper end of the feed rod. The clamping surfaces of the control arms can be close to each other to form a clamping state or far apart to form a released state. When the control arms are in the clamping state, the two control arms form a clamping cavity adapted to the outer contour of the feed rod at their clamping surfaces, and a correction channel 23 for correcting the sliding posture of the nut. The correction channel 23 is located above the clamping cavity.Figures 1 to 3 As shown, the string rod is a circular rod, and due to the small size of the nut, the string rod is thin and long. The fixed string rod is set to control the dynamic arm, so that the upper end of the string rod is located at a specified position, which is beneficial for the threading of the nut. The control arm is installed on the support frame 28 to adapt to the height of the string rod. A pair of control arms can be driven to move relatively by a cylinder to form a clamping or loosening state. Of course, the pair of control arms can be set as a scissor type clamping structure. The ends of the two control arms are provided with gears. The two gears are engaged with a rack. The rack is located between the two gears. The rack is driven to move linearly by a cylinder, thereby driving the two gears to rotate, thereby realizing the closing or opening of the two control arms. Alternatively, the control arm can also adopt other known scissor type clamping structures, and details are not described herein. The two control arms enclose a correction channel in a semicircular shape. In addition, a clamping cavity is enclosed in a circular shape. Therefore, the cavity enclosed between the two control arms is a stepped cavity with a large upper part and a small lower part. When the two control arms are in a clamping state, the string rod is located in the clamping cavity. The clamping cavity restricts the string rod to stabilize the string rod. The clamping cavity can be clamped on the outer circle of the string rod. The clamping cavity can also be in clearance fit with the string rod to limit the swing of the string rod. The inner diameter of the correction channel is slightly larger than the outer diameter of the nut. The nut first passes through the correction channel during the threading process on the string rod. The correction channel limits the deflection of the nut, so that the nut is smoothly threaded on the string rod. After the nut posture is corrected, the control arm loosens the string rod, so that the nut with the corrected posture smoothly slides to the bottom of the string rod.

[0026] In this embodiment, a feeding control device 30 is also included. The feeding control device is provided with a feeding control chute 31 for receiving the nuts conveyed by the conveying device. The correction channel 23 is laterally provided with an inlet 24 which is in communication with the outlet end of the feeding control chute. The linear feeder 12 is supported on the support rod 14. A control block 34 is provided on the linear feeder. The control block serves as the main body of the control device. The feeding control chute 31 is provided on the upper surface of the control block. The feeding control chute is in butt joint with the outlet end of the linear feeding channel 13. The inlet end of the feeding control chute 31 is in a flared structure, which is beneficial for the running posture of the corrected nut and facilitates the smooth entry of the nut into the feeding control chute. Figure 4 As shown, the correction channel has a semicircular structure, and the surrounding angle of the correction channel is about 180 degrees. The gap of the correction channel forms the inlet 24. The nuts in the feeding control chute 31 are sequentially arranged to pass through the inlet 24 into the correction channel and be threaded on the string rod. This structure sequentially corrects the running posture of the nut and corrects the posture of the nut threaded on the string rod, preventing the deflection of the nut.

[0027] In the embodiment, the feeding control device further comprises a blocking piece 32 arranged above the feeding control chute, the feeding inlet is laterally arranged at the upper end of the straightening channel, and the blocking piece is arranged above the outlet end of the feeding control chute and above the straightening channel to limit the deflection of the nut entering the straightening channel from the feeding control chute. Figure 5 As shown in the figure, the control block 34 is covered by a covering block 35, and the covering block covers the feeding control chute 31, wherein a through slot is arranged on the covering block and communicates with the feeding control chute 31, and the blocking piece is an inverted T-shaped piece, the narrow end of the blocking piece extends into the through slot, and the narrow end of the blocking piece extends outward to above the straightening channel, so that the blocking piece is arranged above the outlet end of the feeding control chute and above the straightening channel, and when the nut enters the straightening channel from the feeding control chute, the nut has a downward deflection tendency, and at this time, the blocking piece limits the deflection of the nut by blocking the upward side of the nut, thereby straightening the posture of the nut, so that the nut enters the straightening channel in an approximately horizontal posture and is threaded on the stringing rod.

[0028] In the embodiment, the feeding control device further comprises a pressing piece 33 arranged above the feeding control chute, and the pressing piece can press the nut in the feeding control chute to limit the conveying of the nut in the feeding control chute. Figure 2 and Figure 5 As shown in the figure, the pressing piece is composed of a pressing cylinder fixed at the upper end of the control block 34 and a pressing block connected with the output end of the pressing cylinder, wherein the bottom of the pressing block extends downward into the feeding control chute and is driven downward by the pressing cylinder to press the corresponding nut, thereby limiting the conveying of the single-row nut. In order to ensure that the nut stops conveying forward when the pressing piece is pressed, the height of the straight feeding channel 13 and the feeding control chute 31 should be allowed to pass through one nut to prevent the nut from stacking; of course, the pressing piece can also be directly pressed on the blocking piece 32, and the blocking piece is pressed on the nut to limit the conveying of the nut by pressing the blocking piece downward, at this time, the blocking piece can be arranged as an up-down sliding structure, which will not be described here. The feeding control device can adaptively control the conveying of the nut according to the number of nuts threaded on the stringing rod, and when the number of nuts threaded on the stringing rod reaches a predetermined value, the feeding control device can pause the conveying of the nut and stop the threading of the nut. In order to adapt to the action of the feeding control device, a counting sensor 60 is arranged horizontally opposite to the stringing rod in the embodiment, and a controller 70 is further arranged, the sensor 60 transmits a signal to the controller and controls the action of the feeding control device through the controller, and when the number of nuts threaded on the stringing rod counted by the counting sensor 60 reaches a predetermined value, the controller controls the pressing action of the feeding control device to press the nut and stop the threading of the nut.

[0029] In this embodiment, the conveying device 10 includes a vibratory feeder 11 and a linear feeder 12. The linear feeder has a linear feeding channel 13 connected to the feeding control slide 31. The vibratory feeder is used to store nuts and transport them in a single row according to a set posture through the linear feeding channel into the feeding control slide 31. The linear feeding channel is connected to the discharge port of the vibratory feeder 11. The vibratory feeder is existing technology and can be purchased externally. In this embodiment, a ZDP-DTL-1 type vibratory feeder is purchased externally. The vibratory feeder consists of a hopper, a chassis, and a controller. There is a pulse electromagnet under the hopper of the vibratory feeder, which can make the hopper vibrate vertically. An inclined spring plate drives the hopper to oscillate around its vertical axis. The parts inside the hopper rise along a spiral track due to this vibration. During the rising process, after a series of track screenings or posture changes, the parts can automatically enter the assembly or processing position in a uniform state according to the assembly or processing requirements. Its purpose is to automatically and orderly arrange disordered workpieces and accurately transport them to the next process through vibration. Details will not be elaborated further. The linear feeder is installed on a support rod. The linear feeder can be a straight rod structure with a linear feeding channel. The push force of the nut at the outlet of the vibratory plate 11 on the front nut enables each nut to move within the linear feeding channel. Alternatively, a linear vibratory feeder can be used. The linear vibratory feeder is a vibration source that transports the nuts that have come out of the vibratory plate channel and are arranged in a linear motion. The linear vibratory feeder itself has a built-in vibration motor to achieve vibration, which provides the power for the nuts to move forward within the linear feeding channel. In this embodiment, a ZXZD-DTL-1 type linear vibratory feeder is purchased externally. This linear feeder is also existing technology and will not be elaborated further.

[0030] In this embodiment, the control arms 22 are provided in two pairs, arranged vertically and capable of independent operation. The upper pair of control arms is used to clamp the upper end of the feeding rod. Combined with... Figure 2 As shown, the upper control arm clamps the upper end of the feeding rod, and the lower control arm clamps the feeding rod at the upper middle position. When there is a nut in the correction channel of the upper control arm, the upper control arm is first released, so that the nut falls into the correction channel of the lower control arm. Then the upper control arm closes to clamp, and then the lower control arm is released and closes after the nut falls. This process is repeated until the number of nuts in the feeding rod reaches the preset number. When the number of nuts in the feeding rod reaches the preset number, the clamping device is activated to stop the transmission of nuts. The cooperation of the two control arms ensures that one control arm can always clamp the feeding rod during the feeding process to maintain the stability of the feeding rod's posture.

[0031] In the embodiment, the posture control assembly further comprises a horizontal driver 25, which can drive the control arm to move horizontally to move away from or approach the stringing rod. The horizontal driver is a cylinder, and the control arm is connected to the output end of the cylinder. Through the control of the horizontal driver, the control arm can be moved away from the stringing rod, and the stringing rod can be completely released, so that the nut can fall downward.

[0032] In the embodiment, the stringing device further comprises a base 26, and the lower end of the stringing rod is detachably installed on the base. Specifically, a fixing hole is formed on the base, and the lower end of the stringing rod is sleeved in the fixing hole. The detachable structure can facilitate the replacement of the stringing rod when the stringing rod is full, and can effectively improve the production rhythm. The stringing rod can be a stepped shaft structure with a small upper end and a large lower end. The diameter of the large-diameter section of the stringing rod is greater than the hole diameter of the nut, and the diameter of the small-diameter section is less than the hole diameter of the nut. Through the structure, the nut can be arranged on the small-diameter section and clamped on the shaft shoulder, which facilitates the material taking and replacement of the stringing rod.

[0033] In the embodiment, the stringing device further comprises a vertical driver 27, which can drive the base to move up and down. The vertical driver is a cylinder, and the vertical driver can drive the stringing rod to move up and down. During the stringing process, the upper end of the stringing rod can be located below the upper control arm first. After the nut falls into the correcting channel of the upper control arm, the stringing rod is driven to rise, so that the stringing rod passes through the correcting channel of the upper control arm, and the nut is strung on the stringing rod. At this time, the inner diameter of the clamping cavity formed by the control arm should be slightly larger than the diameter of the stringing rod, so that the stringing rod can smoothly pass through the clamping cavity. Through the structure, the nut can be smoothly strung.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application, and they should be covered in the scope of the claims of the present application.
