[0023] Example:

[0024] See also Figures 1-3 , a carrier variable pitch track, comprising a base plate 1, two track side plates 2 are slidably connected to the base plate 1, and the ends of the two track side plates 2 that are close to each other are each provided with a carrier slideway 3, and the two carrier slideways 3 are symmetrically arranged, two bearing seats 4 are fixedly connected to the base plate 1, and ball screws 5 are rotatably connected in the two bearing seats 4, and travel nuts 6 are fixedly connected to the two track side plates 2, and the two travel nuts 6 are respectively threadedly connected to the circumferential surfaces of the two ball screws 5, and the ends of the two ball screws 5 away from the two track side plates 2 are fixedly connected with driven wheels 7, and the bottom end of the base plate 1 is fixedly connected with two variable pitch motors 8, and the output ends of the two variable pitch motors 8 are fixedly connected with driving wheels 9, and the two driving wheels 9 are respectively connected to the two driven wheels 7 with synchronous belts 10 for transmission, and a feeding assembly is provided on a track side plate 2, and the feeding assembly corresponds to a carrier slideway 3 to realize the mobile conveying of the carrier.

[0025] In this embodiment, two variable pitch motors 8 are connected to an external power supply. When transporting carrier tapes of different specifications, according to the width of the carrier tape, any one of the variable pitch motors 8 is started through the external power supply. The variable pitch motor 8 controls the rotation of the driving wheel 9, and the driving wheel 9 drives the driven wheel 7 to rotate through the synchronous belt 10. The driven wheel 7 causes the ball screw 5 in the bearing block 4 to rotate, and the ball screw 5 causes the travel nut 6 to move. The travel nut 6 drives the track side plate 2 to slide on the bottom plate 1. Both track side plates 2 are adjusted in position in the same way, so as to achieve variable pitch adjustment to adapt to carrier tapes of different specifications and be compatible with asymmetric carrier tapes at the same time. After the adjustment is completed, the carrier tape passes through the two carrier tape chutes 3, and the feeding assembly conveys the carrier tape through the positioning holes of the carrier tape, and the carrier tape remains stable during the conveying process, so as to pick and place electronic components.

[0026] Specifically, the feeding assembly includes two rotating ports 111, two rotating motors 112 and two taping pinwheels 113. Both rotating ports 111 are opened at the top of one track side plate 2, and the two rotating ports 111 communicate with one carrier tape chute 3. The two rotating motors 112 are both fixedly connected to one side end of one track side plate 2, and the output ends of the two rotating motors 112 movably penetrate through one track side plate 2. The two taping pinwheels 113 are respectively fixedly connected to the output ends of the two rotating motors 112, and the two taping pinwheels 113 are respectively located in the two rotating ports 111 corresponding to one carrier tape chute 3.

[0027] In this embodiment, the two rotating ports 111 are electrically connected to the external power supply. When the carrier tape passes through the two carrier tape chutes 3, the positioning holes on the carrier tape pass through the two rotating ports 111 to correspond to the two taping pinwheels 113. The positioning protrusions on the circumferential surfaces of the two taping pinwheels 113 match the carrier tape positioning holes. The two rotating motors 112 control the rotation of the two taping pinwheels 113, and the two taping pinwheels 113 control the movement and conveyance of the carrier tape in the two carrier tape chutes 3 through the positioning holes.

[0028] Specifically, a slide rail module 12 is fixedly connected to the bottom plate 1, and slide base modules 13 are fixedly connected to the bottom ends of the two track side plates 2, and the slide base modules 13 are slidably connected to the slide rail module 12.

[0029] In this embodiment, the two track side plates 2 are slidably connected to the bottom plate 1 through the slide base modules 13 and the slide rail module 12, and the slide base modules 13 and the slide rail module 12 enable the two track side plates 2 to stably move and vary the pitch on the bottom plate 1.

[0030] Specifically, a camera calibration plate 14 is detachably connected to the top ends of the two track side plates 2.

[0031] In this embodiment, the camera calibration plate 14 is arranged above the two track side plates 2 and is used for positioning the detection camera, so that the detection camera can stably detect the placement position of the electronic components in the carrier tape cavities.

[0032] Working principle: When conveying carrier tapes of different specifications, any one of the pitch-changing motors 8 is started by an external power source. The pitch-changing motor 8 controls the rotation of the driving wheel 9. The driving wheel 9 drives the rotation of the driven wheel 7 through the synchronous belt 10. The driven wheel 7 makes the ball screw 5 in the bearing block 4 rotate. The ball screw 5 makes the travel nut 6 move. The travel nut 6 drives the track side plate 2 to slide on the bottom plate 1. Both of the two track side plates 2 adjust their positions in the same way, so as to achieve pitch-changing adjustment to adapt to carrier tapes of different specifications. After the pitch-changing adjustment of the two track side plates 2 is completed, the carrier tape passes through the two carrier tape chutes 3. The positioning holes on the carrier tape pass through the two rotating ports 111 and correspond to the two taping pinwheels 113. The positioning protrusions on the circumferential surfaces of the two taping pinwheels 113 match the carrier tape positioning holes. The two rotating motors 112 control the rotation of the two taping pinwheels 113. The two taping pinwheels 113 control the movement and conveyance of the carrier tape in the two carrier tape chutes 3 through the positioning holes.

[0033] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
