Various widths of carrier tapes are available on the market, requiring conveyor equipment to have corresponding pitch adjustment capabilities to accommodate carrier tapes of different sizes.

[0003] However, the above-mentioned technologies have at least the following technical problems: Traditional variable-pitch conveyor structures are often inconvenient to adjust, have limited accuracy, or require complex servo control systems, resulting in high equipment costs and cumbersome operation. Utility Model Content

[0004] The purpose of this invention is to provide a variable-pitch conveying assembly and a compatible tape and reel assembly machine to solve the problems existing in the prior art.

[0005] The technical solution of this utility model is: a variable pitch conveying assembly for conveying a carrier belt toward a first direction, characterized in that it has a pair of conveying tracks arranged parallel to each other along the first direction, each of the conveying tracks having a track body for supporting the carrier belt, and a carrier belt driving mechanism is provided in conjunction with the track body. The carrier belt driving mechanism includes a pin wheel, the outer edge of which is formed with teeth, the teeth being separable and pluggable into preset holes on the carrier belt, and driving the carrier belt to run toward the first direction through the teeth under the drive of the pin wheel driver. The pair of conveying tracks slide on the base along a second direction perpendicular to the first direction via a pitch adjustment mechanism; The pitch adjustment mechanism includes an adjustment guide rail and a pitch converter; wherein, the adjustment guide rail is fixed on the base along the second direction, and at least one of the conveying rails is slidably disposed on the adjustment guide rail; The pitch converter includes a first positioning hole, a second positioning hole, and a positioning plug. Multiple first and / or second positioning holes are provided. The first and second positioning holes are respectively located on the conveyor rail and the base. The positioning plug can pass through the first positioning hole and be inserted into the second positioning hole.

[0006] Preferably, the conveying track and the base plate are respectively connected to a first positioning plate and a second positioning plate, and the first positioning hole and the second positioning hole are both provided in multiples and are respectively opened on the first positioning plate and the second positioning plate.

[0007] Preferably, the plurality of first positioning holes are formed on the first positioning plate along the first direction, and the projection portions of the plurality of second positioning holes on a plane perpendicular to the first direction overlap.

[0008] Preferably, the adjusting guide rail and the pitch converter are configured as a plurality along the first direction.

[0009] A compatible tape and reel assembly machine includes a variable-pitch conveyor assembly, which forms a tape and reel assembly capable of packaging products through a carrier tape and a cover tape; characterized in that it includes a base, and the base is further provided with: The cover tape feeding mechanism has a cover tape roll capable of storing or outputting the cover tape, the cover tape roll being suspended on a variable pitch conveyor assembly via a cover tape support; The sealing mechanism has a pair of sealers respectively arranged for a pair of conveyor tracks, used to heat seal and fix the two sides of the cover tape to the two sides of the carrier tape respectively; The tape collection mechanism is located at the end of the variable pitch conveyor assembly in the direction of travel and is used to collect the tape assembly formed after the carrier tape and cover tape are heat-sealed. The cutting mechanism, set up in conjunction with the tape receiving mechanism, is used to cut the tape assembly.

[0010] Compared with the prior art, the advantages of this utility model are: This application employs obliquely arranged second positioning holes, causing the projected portions of adjacent holes to overlap in the second direction.

[0013] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 - Figure 3 As shown, a variable-pitch conveyor assembly 200 is disposed on a base 100 for conveying a carrier belt in a first direction. The variable-pitch conveyor assembly 200 has a pair of conveyor tracks 1 arranged parallel to each other along the first direction. Each conveyor track 1 has a track body 11, and a carrier belt drive mechanism 12 is disposed in conjunction with the track body 11. The carrier belt is mounted on the track body 11 and is conveyed in the first direction under the drive of the carrier belt drive mechanism 12.

[0014] Specifically, the carrier belt drive mechanism 12 includes a drive motor 121. The actuating section of the drive motor 121 is equipped with a needle wheel. In this application, the needle wheel is embedded inside the track body 11, and the outer edge of the needle wheel has teeth. The track body 11 has a drive groove 111 corresponding to the teeth. The teeth of the needle wheels located on the two conveying tracks 1 can protrude from the drive groove 111 and be detachably engaged with the pre-set holes on both sides of the carrier belt. The drive motor 121 drives the needle wheel to rotate, and through the cyclic engagement and disengagement of the teeth with different holes on the carrier belt, the carrier belt is driven to run in the first direction.

[0015] In this application, a pair of conveyor tracks 1 slide on the base 100 along a second direction perpendicular to the first direction via a pitch adjustment mechanism 2, thereby enabling the two pinwheels to adapt to carrier belts of different widths and engage with the holes on both sides of the carrier belt to convey carrier belts of different specifications.

[0016] Furthermore, the pitch adjustment mechanism 2 includes an adjustment guide rail 21 and a pitch converter 22.

[0017] The adjusting guide rail 21 is fixed on the base 100 along the second direction, and at least one conveying rail 1 is slidably disposed on the adjusting guide rail 21.

[0018] The pitch converter 22 includes a first positioning plate 221, a second positioning plate 222, and a positioning insert 223. The first positioning plate 221 and the second positioning plate 222 are respectively provided with a first positioning hole 2211 and a second positioning hole 2221, and the first positioning plate 221 and the second positioning plate 222 are respectively fixed to the conveying track 1 and the base 100. In this embodiment, multiple first positioning holes 2211 and multiple second positioning holes 2221 are provided. The positioning insert 223 can pass through different first positioning holes 2211 and be inserted into the corresponding second positioning hole 2221, so that a pair of conveying tracks 1 have different pitches.

[0019] Specifically, in this application, a plurality of first positioning holes 2211 are formed on the first positioning plate 221 along the first direction, and a plurality of second positioning holes 2221 are arranged obliquely on the second positioning plate 222, such that the projection of any second positioning hole 2221 on a plane perpendicular to the first direction coincides with the projection of the adjacent second positioning hole 2221 on the same plane. With this arrangement, without reducing the size of the second positioning holes 2221, the arrangement of adjacent second positioning holes 2221 in the second direction is more compact, thereby reducing the minimum adjustment amount.

[0020] Furthermore, multiple adjusting guide rails 21 and pitch converters 22 are configured along the first direction, capable of supporting both ends of the conveying track 1.

[0021] like Figure 4 As shown, this application also provides a compatible tape and reel assembly machine, which uses a variable pitch conveyor assembly 200 to match the conveyed carrier tape with the cover tape to form a tape and reel assembly that can be packaged into products.

[0022] The compatible tape and reel assembly machine includes a base 100, and the base 100 is further provided with: The cover tape feeding mechanism 300 has a cover tape roll 310 capable of storing or outputting the cover tape, the cover tape roll 310 being suspended on the variable pitch conveyor assembly 200 via a cover tape bracket 320. The packaging mechanism 400 has a pair of packaging devices respectively arranged for a pair of conveyor tracks 1. In the working state, the two sides of the cover tape output by the cover tape roll 310 are respectively located below the pair of packaging devices, so that the pair of packaging devices can heat seal and fix the two sides of the cover tape to the two sides of the carrier tape respectively. The tape collection mechanism 500 is located at the end of the running direction of the variable pitch conveyor assembly 200 and is used to collect the tape assembly formed after the carrier tape and cover tape are heat-sealed. The cutting mechanism 600, in conjunction with the tape receiving mechanism 500, is used to cut the tape assembly.
