Description

Technical Field

[0001] The present invention relates to the field of packaging of cylindrical terminals, and particularly to an automatic tape packaging machine for clamping individual cylindrical terminals into preset clamping slots on a roll-shaped tape. Background Art

[0002] As is well known, probes are widely used in testing, electrical connection and other applications and belong to a kind of precision components.

[0003] Among them, during the processing of probes, according to the process requirements, it is necessary to perform gold plating on the cylindrical terminals in the probes. Since the machining site of the cylindrical terminals and the gold plating site of the cylindrical terminals are in different workshops, for the convenience of transporting the cylindrical terminals, individual cylindrical terminals are clamped into preset clamping slots on the tape, and the tape realizes the release and winding actions of the tape through the coordinated cooperation of the unwinding wheel and the winding wheel, so as to achieve the purpose of batch packaging of the cylindrical terminals with a roll-shaped tape and facilitate transportation.

[0004] However, the feeding operation of clamping individual cylindrical terminals into different clamping slots in the free section released by the unwinding wheel of the roll-shaped tape is completed by workers. And before the workers clamp the cylindrical terminals into different clamping slots in the free section, they need to randomly pick a cylindrical terminal from the messy pile of cylindrical terminals and then adjust the orientation of the picked cylindrical terminal so as to correctly clamp the cylindrical terminal into the clamping slot in the free section. This increases the burden on the operator to clamp the cylindrical terminals into different clamping slots in the free section and cannot realize the automatic packaging of the cylindrical terminals by the tape.

[0005] Therefore, there is an urgent need for an automatic tape packaging machine that can realize the automatic packaging of cylindrical terminals and effectively avoid the generation of empty packages to overcome the above defects. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic tape packaging machine that can realize the automatic packaging of cylindrical terminals and effectively avoid the generation of empty packages.

[0007] To achieve the above object, the automatic carrier tape packaging machine of the present invention includes a frame, a feeding gear, a conveying trough, a hanging shaft for hanging and unwinding a roll-shaped carrier tape, a rotating shaft rotatably assembled on the frame, a winding wheel rotatably sleeved on the rotating shaft around the rotating shaft, a winding wheel assembled on the frame, a vibrating disk for sorting and conveying disordered cylindrical terminals, and a rotating motor for driving the feeding gear and the rotating shaft to rotate synchronously. The hanging shaft, the vibrating disk, the conveying trough and the feeding gear are respectively located above the frame and assembled at the frame. The conveying trough has an inclined channel for continuously conveying the cylindrical terminals sent by the vibrating disk forward, and the inclined channel is inclined downward in a direction away from the vibrating disk; the feeding gear is located beside the front side of the conveying trough along the conveying direction of the cylindrical terminals in the inclined channel, and a plurality of receiving tooth grooves are formed on the periphery of the feeding gear and are arranged in a circle at equal intervals along the circumferential direction of the feeding gear. During the rotation of the feeding gear, any one of the receiving tooth grooves rotates to a material receiving position aligned with the inclined channel; the rotating motor and the rotating shaft are arranged in sequence along the conveying direction of the cylindrical terminals in the inclined channel, the hanging shaft is located at the corresponding rear side of the conveying trough along the conveying direction of the cylindrical terminals in the inclined channel, and the hanging shaft and the rotating shaft are arranged with the front end higher and the rear end lower. The free section released from the roll-shaped carrier tape obliquely crosses the feeding gear downward from above the feeding gear and is wound and tightened by the winding wheel; wherein, while the rotating motor drives the feeding gear to drive the cylindrical terminals sliding into the receiving tooth groove from the inclined channel to be clamped in the clamping notch of the free section, the cylindrical terminals also pull the free section to move forward towards the winding wheel, and then the rotating shaft slips relative to the winding wheel when driving the winding wheel to wind and tighten the forward moving part of the free section.

[0008] Preferably, the automatic carrier tape packaging machine of the present invention further includes a feeding distance maintaining block assembled on the frame and located beside the feeding gear along the radial direction of the feeding gear. The feeding distance maintaining block has a sliding through channel extending along the alignment direction of the hanging shaft and the rotating shaft and for the free section to slide through, and the sliding through channel corresponds to the periphery of the feeding gear.

[0009] Preferably, the sliding through channel includes a straight channel and a straight notch connected to one side of the straight channel and aligned with the periphery of the feeding gear. The straight notch faces the periphery of the feeding gear, and the free section is simultaneously placed in the straight channel and the straight notch.

[0010] Preferably, a first pulley is coaxially fixed to the feeding gear. A second pulley aligned with the first pulley and a third pulley offset from the second pulley are fixedly sleeved on the output end of the rotating motor. The winding wheel is sleeved on the first end of the rotating shaft. A fourth pulley aligned with the third pulley is fixed to the second end of the rotating shaft opposite to the first end. A first belt is sleeved on the first pulley and the second pulley. A second belt is sleeved on the fourth pulley and the third pulley.

[0011] Preferably, a pressure regulating screw cap is threadedly connected to the first end of the rotating shaft. A pressure regulating spring is sleeved on the rotating shaft. The pressure regulating spring elastically abuts between the winding wheel and the pressure regulating screw cap. By adjusting the tightness of the pressure regulating spring with the pressure regulating screw cap, the frictional resistance between the winding wheel and the rotating shaft is correspondingly adjusted.

[0012] Preferably, the automatic carrier tape packaging machine of the present invention further includes a first lateral limiting block and a second lateral limiting block that are jointly used to limit the axial movement of the cylindrical terminals in the receiving tooth grooves along the axial direction of the feeding gear. The first lateral limiting block and the second lateral limiting block are located beside the front side of the conveying trough body along the direction of conveying the cylindrical terminals in the inclined channel. The first lateral limiting block is also axially aligned and spaced apart from the second lateral limiting block along the axial direction of the feeding gear. The feeding gear is partially located between the first lateral limiting block and the second lateral limiting block. The receiving tooth grooves in the receiving position are also axially aligned with the first lateral limiting block and the second lateral limiting block respectively.

[0013] Preferably, both the first lateral limiting block and the second lateral limiting block are arranged to extend circumferentially along the feeding gear. The rear ends of both the first lateral limiting block and the second lateral limiting block extend downward beyond the receiving tooth grooves in the receiving position.

[0014] Preferably, the side surface of the first lateral limiting block facing the second lateral limiting block has a planar portion perpendicular to the axis line of the feeding gear. The side surface of the second lateral limiting block facing the first lateral limiting block has a planar portion perpendicular to the axis line of the feeding gear.

[0015] Preferably, in the first lateral limiting block, the side surface of the first lateral limiting block facing the second lateral limiting block further has an inclined surface portion located between the planar portion and the conveying trough body. The inclined surface portion inclines away from the second lateral limiting block. In the second lateral limiting block, the side surface of the second lateral limiting block facing the first lateral limiting block further has an inclined surface portion located between the planar portion and the conveying trough body. The inclined surface portion inclines away from the first lateral limiting block.

[0016] Preferably, an avoidance groove is formed in the side wall of the feeding gear and arranged in a circle along the circumferential direction of the feeding gear. The avoidance groove cuts the receiving tooth groove into two parts. A guide wheel for guiding the free section is further arranged above the conveying trough body. The guide wheel is assembled on the frame. A wheel groove extending one week along the circumferential direction of the guide wheel is formed in the side wall of the guide wheel, and the free section passes through the wheel groove from below.

[0017] Compared with the prior art, with the cooperation of the vibrating disc, the conveying trough body, the feeding gear, the rotating motor, the winding wheel and the hanging shaft, during the process of driving the feeding gear to rotate by the rotating motor, the cylindrical terminals sorted and conveyed by the vibrating disc slide into the receiving tooth groove aligned with the inclined channel along the inclined channel of the conveying trough body. Due to the downward inclination of the inclined channel, the cylindrical terminals can slide more smoothly into the aligned receiving tooth groove under the action of their own weight; at the same time, the cylindrical terminals sliding into the receiving tooth groove are clamped in the clamping notch of the free section released from the rolled tape during the rotation of the feeding gear, so as to achieve the purpose of automatically clamping each cylindrical terminal into different clamping notches of the free section. Furthermore, during the process of the cylindrical terminals in the receiving tooth groove being clamped in the clamping notch of the free section following the rotation of the feeding gear, the cylindrical terminals also pull the free section to move forward towards the winding wheel, so that the forward moving part of the free section is in a loose state. Then, when the rotating shaft drives the winding wheel to wind the forward moving part of the free section until it is tightened, the rotating shaft slips relative to the winding wheel. That is, when the forward moving part is tightened, the pulling force of the free section on the winding wheel is greater than the frictional resistance between the winding wheel and the rotating shaft, so that the rotating shaft cannot drive the winding wheel to rotate normally, and thus the forward movement of the free section will not be caused. Therefore, the situation that there is no cylindrical terminal in the clamping notch of the free section is effectively avoided, and the problem of empty bags generated in automatic packaging is solved.

[0030] In order to describe in detail the technical content and structural features of the present invention, the following further description is made in conjunction with the embodiments and with reference to the drawings.

[0031] Please refer to Figure 1 and Figure 2 , the automatic carrier tape packing machine 100 of the present invention is used to sort the disordered cylindrical terminals 210, and then respectively and correspondingly snap the sorted cylindrical terminals 210 into different snap slots 222 of the free section 221 released from the roll-shaped carrier tape 220, so as to achieve the purpose of automatically packing the cylindrical terminals 210 on the roll-shaped carrier tape 220.

[0032] And in conjunction with Figure 8, the automatic carrier tape packaging machine 100 of the present invention includes a frame 10, a feeding gear 20, a conveying trough 30, a hanging shaft 40 for hanging and unwinding a roll-shaped carrier tape 220, a rotating shaft 11 rotatably assembled on the frame 10, a winding wheel 50 rotatably sleeved on the rotating shaft 11, a vibrating disk 60 for sorting and conveying disordered cylindrical terminals 210, and a rotating motor 70 for driving the feeding gear 20 and the rotating shaft 11 to rotate synchronously. The hanging shaft 40, the vibrating disk 60, the conveying trough 30, and the feeding gear 20 are each located above the frame 10 and assembled at the frame 10, and the frame 10 provides a supporting function and an assembling place for the hanging shaft 40, the vibrating disk 60, the conveying trough 30, and the feeding gear 20; the conveying trough 30 has an inclined channel 31 for continuously conveying the cylindrical terminals 210 sent by the vibrating disk 60 forward, and the inclined channel 31 is inclined downward in a direction away from the vibrating disk 60, so that the cylindrical terminals 210 entering the inclined channel 31 can slide more smoothly towards the feeding gear 20 under their own weight; the feeding gear 20 is located beside the front side of the conveying trough 30 along the direction of conveying the cylindrical terminals 210 in the inclined channel 31 (i.e., the direction indicated by arrow A), so that the feeding gear 20 and the conveying trough 30 are more compact. A plurality of receiving tooth grooves 22 are formed on the periphery 21 of the feeding gear 20 and are arranged in a circle at equal intervals along the circumferential direction of the feeding gear 20. During the rotation of the feeding gear 20, any one of the receiving tooth grooves 22 rotates to the receiving position aligned with the inclined channel 31, so that the cylindrical terminals 210 in the inclined channel 31 can slide into one of the receiving tooth grooves 22 aligned with the inclined channel 31; the rotating motor 70 and the rotating shaft 11 are arranged in sequence along the direction of conveying the cylindrical terminals 210 in the inclined channel 31, and the hanging shaft 40 is located at the corresponding rear side of the conveying trough 30 along the direction of conveying the cylindrical terminals 210 in the inclined channel 31, and the hanging shaft 40 and the rotating shaft 11 are arranged with the front higher than the rear; the free section 221 released from the roll-shaped carrier tape 220 obliquely crosses the feeding gear 20 downward from above the feeding gear 20 and is wound and tightened by the winding wheel 50, so that the free section 221 is in a tightened state; therefore, when the rotating motor 70 drives the feeding gear 20 to drive the cylindrical terminals 210 that slide into the receiving tooth grooves 22 from the inclined channel 31 to be clamped in the clamping notch 222 of the free section 221, the cylindrical terminals 210 also pull the free section 221 to move forward towards the winding wheel 50, and then the rotating shaft 11 slips relative to the winding wheel 50 when driving the winding wheel 50 to wind the forward-moving part of the free section 221 to be tightened, that is, when the forward-moving part is tightened, the pulling force of the free section 221 on the winding wheel 50 is greater than the frictional resistance between the winding wheel 50 and the rotating shaft 11, so that the rotating shaft 11 that rotates synchronously with the feeding gear 20 cannot normally drive the winding wheel 50 to perform a winding motion. Specifically, in Figure 1In the embodiment, the vibration plate 60 is located between the conveying trough 30 and the hanging shaft 40 along the direction of conveying the columnar terminal 210 through the inclined channel 31, so that the conveying trough 30, the vibration plate 60 and the hanging shaft 40 are more compact; in addition, the specific way of slipping will be described below, so it will not be described in detail here. More specifically, as follows:

[0033] If Figure 1 、 Figure 2 and Figure 12 As shown in FIG. 1 , the automatic tape packaging machine 100 of the present invention further includes a feeding distance holding block 80 which is mounted on the frame 10 and is located on the side of the feeding gear 20 along the radial direction of the feeding gear 20, so that the feeding distance holding block 80 is located obliquely above the feeding gear 20 and away from the conveying trough 30. The feeding distance holding block 80 has a sliding passage 81 which extends along the alignment direction of the hanging shaft 40 and the rotating shaft 11 (i.e., the direction indicated by the double arrow B) and is provided for the free section 221 to slide through. The sliding passage 81 is aligned with the The peripheral edge 21 of the feeding gear 20 corresponds to each other, so that the distance between the penetration part of the free section 221 that penetrates the sliding passage 81 and the feeding gear 20 remains unchanged by means of the feeding distance retaining block 80, effectively preventing the penetration part from shaking relative to the feeding gear 20 when the feeding gear 20 clamps the column terminal 210 in the clamping notch 222 of the penetration part, thereby effectively improving the reliability of the feeding gear 20 clamping the column terminal 210 in the clamping notch 222 of the free section 221. Specifically, in Figure 12 , the sliding channel 81 includes a straight channel 811 and a straight notch 812 connected to one side of the straight channel 811 and aligned with the peripheral edge 21 of the feeding gear 20, the straight notch 812 faces the peripheral edge 21 of the feeding gear 20, and the free section 221 is inserted into the straight channel 811 and the straight notch 812 at the same time, so as to limit the free section 221 to slide downward only along the alignment direction of the hanging shaft 40 and the winding wheel 50 with the help of the straight channel 811, and provide an avoidance space for the free section 221 to form a card-mounting notch 222 with the help of the straight notch 812. It should be noted that the circumferential spacing between any two adjacent receiving tooth grooves 22 is exactly equal to the spacing between any two adjacent card-mounting notches 222, so as to ensure that the columnar terminal 210 in each receiving tooth groove 22 is just card-mounted in a corresponding card-mounting notch 222 in the process of following the rotation of the feeding gear 20.

[0034] If Figure 1 ​​As shown in the figure, a first pulley 71 is coaxially fixed to the feeding gear 20, such that the first pulley 71 is fixed to the feeding gear 20 and rotates together with it. The output end of the rotating motor 70 is fixedly sleeved with a second pulley 72 aligned with the first pulley 71 and a third pulley 73 misaligned with the second pulley 72, to ensure that the rotating motor 70 can drive the second pulley 72 and the third pulley 73 to rotate synchronously; the winding wheel 50 is sleeved on the first end of the rotating shaft 11, such that when the pulling force of the free section 221 tightened by the winding wheel 50 on the winding wheel 50 is greater than the frictional resistance between the winding wheel 50 and the rotating shaft 11, the winding wheel 50 slips relative to the rotating shaft 11. At this time, the rotating motor 70 can no longer drive the winding wheel 50 to rotate normally through the rotating shaft 11; and a fourth pulley 74 aligned with the third pulley 73 is fixed to the opposite second end of the rotating shaft 11, such that the rotating shaft 11 is fixed to the fourth pulley 74 and rotates together with it; and a first belt 75 is sleeved on the first pulley 71 and the second pulley 72, and a second belt 76 is sleeved on the fourth pulley 74 and the third pulley 73; therefore, the rotating shaft 11 slips relative to the winding wheel 50 when the cylindrical terminal 210 does not pull the free section 221 forward. This is because the free section 221 is tightened by the winding wheel 50 when it is not driven forward by the cylindrical terminal 210, and the pulling force of the tightened free section 221 on the winding wheel 50 is greater than the frictional resistance between the winding wheel 50 and the rotating shaft 11, thereby causing the rotating shaft 11 rotating together with the fourth pulley 74 to slip relative to the winding wheel 50, thus preventing the winding wheel 50 from winding the forward-moving part of the free section 221 that is not driven forward by the cylindrical terminal 210, effectively avoiding the defect of empty packages in the rolled carrier tape 220. Specifically, in Figure 3 In order to flexibly adjust the frictional resistance between the winding wheel 50 and the rotating shaft 11, a pressure-regulating cap 12 is threadedly connected to the first end of the rotating shaft 11. A pressure-regulating spring 13 is sleeved on the rotating shaft 11, and the pressure-regulating spring 13 elastically abuts between the winding wheel 50 and the pressure-regulating cap 12. Therefore, by adjusting the tightness of the pressure-regulating spring 13 with the pressure-regulating cap 12, the frictional resistance between the winding wheel 50 and the rotating shaft 11 can be correspondingly adjusted; for example, when it is necessary to increase the frictional resistance between the winding wheel 50 and the rotating shaft 11, at this time, continue to operate the pressure-regulating cap 12 in the screwing-in direction, such that the pressure-regulating cap 12 further compresses the pressure-regulating spring 13, increasing the elastic force of the pressure-regulating spring 13 between the winding wheel 50 and the rotating shaft 11, thereby achieving the purpose of increasing the frictional resistance between the winding wheel 50 and the rotating shaft 11; on the contrary, operate the pressure-regulating cap 12 in the screwing-out direction, such that the pressure-regulating cap 12 gradually loosens the compression of the pressure-regulating spring 13, thereby reducing the elastic force of the pressure-regulating spring 13 between the winding wheel 50 and the rotating shaft 11, thus reducing the frictional resistance between the winding wheel 50 and the rotating shaft 11.

[0035] Such as Figures 4 to 7As shown, the automatic tape packaging machine 100 of the present invention also includes a first lateral stopper 91 and a second lateral stopper 92 which are used together to limit the movement of the column terminal 210 in the receiving tooth groove 22 along the axial direction (i.e., indicated by the double arrow C) of the feeding gear 20. The first lateral stopper 91 and the second lateral stopper 92 are located beside the front side of the conveying trough body 30 along the direction in which the column terminal 210 is conveyed through the inclined channel 31. The first lateral stopper 91 is also aligned and separated from the second lateral stopper 92 along the axial direction of the feeding gear 20. The feeding gear 20 is partially located between the first lateral stopper 91 and the second lateral stopper 92. The receiving tooth groove 22 in the material receiving position is also aligned with the first lateral stopper 91 and the second lateral stopper 92 along the axial direction of the feeding gear 20, respectively. The state is shown in Figure 9 As shown, that is, in Figure 9 In , the receiving tooth groove 22 where the top columnar terminal 210 is located is the receiving tooth groove 22 at the material receiving position; wherein, with the cooperation of the first lateral limit block 91 and the second lateral limit block 92, the reliability of the columnar terminal 210 at the inclined channel 31 sliding into the receiving tooth groove 22 aligned with the inclined channel 31 is effectively ensured, and in the process of the columnar terminal 210 in the receiving tooth groove 22 following the feeding gear 20 to rotate toward the free section 221, the first lateral limit block 91 and the second lateral limit block 92 axially limit the columnar terminal 210 in the receiving tooth groove 22, effectively preventing the columnar terminal 210 in the receiving tooth groove 22 from running around, and improving the reliability of the columnar terminal 210 in the receiving tooth groove 22 being smoothly mounted in the mounting notch 222 of the free section 221 in the process of following the feeding gear 20 to rotate toward the free section 221. Specifically, in Figures 4 to 8 In , the first lateral limit block 91 and the second lateral limit block 92 are both arranged along the circumferential extension of the feeding gear 20, and the rear ends of the first lateral limit block 91 and the second lateral limit block 92 each extend downward beyond the receiving tooth groove 22 at the material receiving position, as shown in Figure 9 As shown in , the purpose of such design is to improve the reliability of the column terminal 210 at the inclined channel 31 sliding into the receiving tooth groove 31 aligned with the inclined channel 31. More specifically, in Figure 10 In the embodiment, the side surface 91a of the first lateral stopper 91 facing the second lateral stopper 92 has a plane portion 911 perpendicular to the axis of the feeding gear 20, and the side surface 92a of the second lateral stopper 92 facing the first lateral stopper 91 has a plane portion 921 perpendicular to the axis of the feeding gear 20. This design makes the plane portions 911 and 921 parallel to each other, ensuring that the spacing between the plane portions 911 and 921 is the same everywhere, thereby more effectively limiting the columnar terminal 210 in the receiving tooth groove 22 from running around in the process of following the feeding gear 20 to rotate toward the free section 221.

[0036] Among them, such as Figure 9 andFigure 10 As shown, to further facilitate the cylindrical terminal 210 on the inclined channel 31 to slide into the receiving tooth groove 22 in the receiving position, in the first lateral limiting block 91, the side surface 91a of the first lateral limiting block 91 facing the second lateral limiting block 92 further has an inclined surface portion 912 located between the flat portion 911 and the conveying trough body 30, and the inclined surface portion 912 is inclined in a direction away from the second lateral limiting block 92; in the second lateral limiting block 92, the side surface 92a of the second lateral limiting block 92 facing the first lateral limiting block 91 further has an inclined surface portion 922 located between the flat portion 911 and the conveying trough body 30, and the inclined surface portion 922 is inclined in a direction away from the first lateral limiting block 91; preferably, the inclined surface portion 912 and the inclined surface portion 922 are arranged in central symmetry, so as to expand the space at the ends of both the side surface 91a and the side surface 92a close to the conveying trough body 30 by means of the settings of the inclined surface portion 912 and the inclined surface portion 922. To avoid the middle part of the cylindrical terminal 210, the side wall of the feeding gear 20 is provided with an avoidance groove 23 arranged in a circle along the circumferential direction of the feeding gear 20, and the avoidance groove 23 cuts the receiving tooth groove 22 into two parts. In addition, the receiving tooth groove 22 in the receiving position is respectively aligned with the rear ends of the inclined surface portion 912 (922), and the state is shown in Figure 9 shown in the figure.

[0037] Combined with the attached drawings, the working principle of the automatic tape packaging machine of the present invention will be described: During operation, the rotating motor 70 drives the feeding gear 20 to rotate counterclockwise in the Figure 8 while also driving the rotating shaft 11 to rotate through the third pulley 73, the second belt 76 and the fourth pulley 74; due to the rotatable sleeve fit between the winding wheel 50 and the rotating shaft 11, the rotating rotating shaft 11 drives the winding wheel 50 to tighten the free section 221 of the wound tape 210 manually pulled out and the end of which is connected to the winding wheel 50; when the pulling force of the tightened free section 221 on the winding wheel 50 is greater than the frictional resistance between the winding wheel 50 and the rotating shaft 11, at this time, the rotating shaft 11 slips relative to the winding wheel 50, resulting in the rotating shaft 11 being unable to drive the winding wheel 50 to rotate normally. Therefore, the feeding gear 20 drives the cylindrical terminal 210 in the receiving tooth groove 22 in the Figure 8The rotating shaft 11 is then rotated counterclockwise until it enters the opening of the card slot 222. At this time, the rotating shaft 11 slips relative to the winding wheel 50. When the cylindrical terminal 210 rotates with the feeding gear 20 until it abuts against the groove wall of the card slot 222, the cylindrical terminal 210 not only continues to slide into the card slot 222 while following the rotation of the feeding gear 20, but also pulls the free section 221 downward, so that the forward part of the free section 221 is in a loose state relative to the winding wheel 50. Because the forward part of the free section 221 is in an open state, , causing the pulling force of the free section 221 on the take-up wheel 50 to be much smaller than the friction resistance between the take-up wheel 50 and the rotating shaft 11, thus restoring the driving function of the rotating shaft 11 on the take-up wheel 50, so that the take-up wheel 50 rotates again to rewind the forward part of the free section 221, until the free section 221 is tightened by the take-up wheel 50 again; when there is no column terminal 210 in the receiving tooth groove 22, the free section 221 remains stationary due to the pull of the no column terminal 210, thus avoiding that some of the card-mounting slots 222 in the roll carrier 220 do not have the column terminal 210 installed. Among them, during the process of the column terminal 210 being card-mounted in the card-mounting slot 222 of the free section 221, the vibration plate 60 transports the column terminal 210 to the inclined channel 31, and the first lateral limit block 91 and the second lateral limit block 92 prevent the column terminal 210 from running axially.

[0038] Compared with the prior art, with the cooperation of the vibrating bowl 60, the conveying trough body 30, the feeding gear 20, the rotating motor 70, the winding wheel 50 and the hanging shaft 40, during the process of the rotating motor 70 driving the feeding gear 20 to rotate, the cylindrical terminals 210 sorted and conveyed by the vibrating bowl 60 slide along the inclined channel 31 of the conveying trough body 30 into the receiving tooth grooves 22 aligned with the inclined channel 31. Since the inclined channel 31 slopes downward, the cylindrical terminals 210 can slide more smoothly into the aligned receiving tooth grooves 22 under the action of their own weights; meanwhile, the cylindrical terminals 210 that slide into the receiving tooth grooves 22 are clamped in the clamping notches 222 of the free section 221 released from the coiled carrier tape 220 during the rotation of the feeding gear 20, achieving the purpose of automatically clamping the cylindrical terminals 210 into different clamping notches 222 of the free section 221 one by one. Furthermore, during the process of the cylindrical terminals 210 in the receiving tooth grooves 22 following the rotation of the feeding gear 20 and being clamped in the clamping notches 222 of the free section 221, the cylindrical terminals 210 also pull the free section 221 to move forward towards the winding wheel 50, making the forward-moving part of the free section 221 in a loose state. Then, when the rotating shaft 11 drives the winding wheel 50 to wind the forward-moving part of the free section 221 until it is taut, the rotating shaft 11 slips relative to the winding wheel 50, that is, when the forward-moving part is taut, the pulling force of the free section 221 on the winding wheel 50 is greater than the frictional resistance between the winding wheel 50 and the rotating shaft 11, making the rotating shaft 11 unable to drive the winding wheel 50 to rotate normally, so the forward movement of the free section 221 will not be caused. Therefore, the situation where there are no cylindrical terminals 210 in the clamping notches 222 of the free section 221 is effectively avoided, and the problem of empty packages generated during automatic packaging is solved.

[0039] In summary, the unwinding of the coiled carrier tape 220 on the hanging shaft 40 is pulled by the cylindrical terminals 210 that follow the rotation of the feeding gear 20 and are clamped in the clamping notches 222 of the free section 221. Therefore, the synchronization of unwinding and the clamping of the cylindrical terminals 210 is achieved; in addition, during the operation of the rotating motor 70, the feeding gear 20 and the rotating shaft 11 are driven by the rotating motor 70 to rotate synchronously.

[0040] The above-disclosed are only the preferred examples of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, all equivalent changes made according to the claims of the present invention fall within the scope covered by the present invention.
