Description

Technical Field

[0001] This utility model relates to the field of tape conveying equipment, specifically to a flexible tape high-precision conveying track structure. Background Technology

[0002] SMT, or Surface Mount Technology, is currently the most popular technology and process in the electronics assembly industry. It compresses traditional electronic components into devices that are only a fraction of their original size, thus achieving high density, high reliability, miniaturization, low cost, and automation in electronic product assembly. Currently, advanced electronic products, especially computer and communication electronic products, widely adopt SMT technology.

[0003] In SMT production, conveyor tracks are used for feeding materials. Existing conveyor tracks cannot effectively limit the movement of flexible tape, causing it to oscillate within the conveyor path. This not only affects counting but also leads to inaccurate subsequent positioning, resulting in defective products. While some conveyor tracks can limit tape oscillation by adjusting the width of the conveyor path, the tape still exhibits vertical displacement, impacting usability. Therefore, there is a need for a simple, high-precision flexible tape conveyor track structure suitable for positional constraint of the tape. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a novel flexible tape-based high-precision transmission track structure, which solves the problems that are unfavorable to flexible tape transmission in existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible tape-making high-precision transmission track structure for constraining the position of tape includes a base plate, a cam drive component, a track fixing component, and a moving track component.

[0013] Furthermore, the moving rail component includes a moving rail support, a moving rail base plate, a moving rail guide plate, a moving rail guide component, and a moving rail drive component. The moving rail support is slidably mounted on the base plate via the moving rail guide component.

The moving rail guide plate is mounted on the moving rail base plate. A moving rail guide strip is provided along the length of the moving rail guide plate on the side closest to the fixed rail plate.

[0014] Furthermore, the fixed-side track bar and the moving-rail guide bar are respectively disposed on the lower part of the side of the fixed track plate and the moving-rail guide plate that are close to each other, so that the side of the fixed track plate and the moving-rail guide plate that are close to each other, together with the cover plate, form a material channel.

[0015] Furthermore, the cam drive component includes a camshaft seat, a cam shaft, and a cam drive motor. The camshaft seat is located on the side of the fixed rail bracket away from the moving rail component. The cam shaft is rotatably mounted in the camshaft seat and is parallel to the fixed-side rail. The cam drive motor is located on the lower side of the base plate, and its working end is connected to the cam shaft. The cam shaft is provided with a cover cam to contact the Y-axis cam follower.

[0016] Furthermore, a working opening is provided in the middle of the track support on the lower side of the fixed track plate.

[0018] Compared to existing technologies, the advantages of this invention are that, by adopting the above solution, the structure is simple. First, the cam drive component drives the Y-axis cam follower to apply force to the fixed rail tie rod, thereby pulling the cover plate mounting seat to slide backward along the Y-axis guide rail. At the same time, the guide slope of the Z-axis guide seat forces the Z-axis cam follower to move upward, thereby driving the cover plate to move upward along the Z-axis guide rail, so as to remove the cover plate from the fixed edge track. Then, the tape is introduced into the fixed edge track, and the moving rail component adjusts the distance between the tape and the fixed edge track according to the width of the tape.

[0019] Subsequently, the cam drive component operates without applying force to the Y-axis cam follower. Under the tension of the fixed rail spring, the fixed rail tie rod pushes the cover plate mounting seat to slide forward along the Y-axis guide rail. At the same time, the Z-axis cam follower moves down along the guide slope of the Z-axis guide seat to drive the cover plate to move down along the Z-axis guide rail, so as to press the cover plate onto the fixed edge track to prevent the flexible tape from shifting laterally or floating up and down during transmission.

[0020] Two guide rail components are installed on the guide rail support to achieve bidirectional reciprocating transmission and unidirectional through transmission of flexible tape. The flexible tape can enter from both ends of the track and move towards the center of the track under the action of the two guide rail components. Alternatively, it can enter from one end of the track and be driven by the power source of the guide rail component at the other end to achieve unidirectional transmission through the entire track. In either transmission mode, the guide rail components dynamically apply lateral and vertical limiting forces to prevent the flexible tape from shifting laterally or floating up and down. This effectively solves the problems of uneven tension, insufficient positioning accuracy, and transmission stability of flexible tape in multidirectional transmission. It is especially suitable for automated production applications of SMT chip taping and has great market application value. Attached Figure Description

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0033] One embodiment of this utility model is as follows: Figure 1 , 2 As shown in Figures 3 and 4, this flexible tape high-precision transmission track structure is used to constrain the position of the tape. It includes a base plate 1, a cam drive component 2, a track fixing component 3, and a moving track component 4. The track fixing component 3 and the moving track component 4 are arranged opposite to each other on the base plate 1 to form a material channel. The track fixing component 3 includes a track fixing bracket 31, a fixed track plate 32, a first track fixing assembly 33, and a second track fixing assembly 34. The fixed track plate 32 is disposed on the top side of the track fixing bracket 31. A fixed edge track strip 321 is arranged along its own length direction on the side of the fixed track plate 32 near the moving track component 4. The first track fixing assembly 33 and the second track fixing assembly 34 are symmetrically arranged at both ends of the fixed track plate 32.

[0034] The first track fixing assembly 33 includes a cover plate mounting seat 331, a cover pressure plate 332, a Y-guide rail component 333, a Z-guide rail component 334, a track fixing rod 335, a track fixing spring component 336, a Y-direction cam follower 337, and a Z-direction cam follower 338. The cover plate mounting seat 331 is slidably disposed on the top side of the fixed track plate 32 via the Y-guide rail component 333. The Z-guide rail component 334 is disposed on the side of the cover plate mounting seat 331 near the moving track component 4. The cover pressure plate 332 is slidably connected to the cover plate mounting seat 331 via the Z-guide rail component 334 and is located on the upper side of the fixed edge track bar 321.

[0035] The cam drive component 2 is disposed on the side of the fixed rail bracket 31 away from the moving rail component 4. The fixed rail tie rod 335 is located on the side of the cam drive component 2. The bottom of the fixed rail tie rod 335 is rotatably disposed on the base plate 1. The Y-axis cam follower 337 is disposed on the lower part of the fixed rail tie rod 335 and contacts the working end of the cam drive component 2. The upper part of the fixed rail tie rod 335 is connected to the fixed rail bracket 31 through the fixed rail tension spring 336. The top of the fixed rail tie rod 335 is connected to the cover plate mounting seat 331. The Z-axis cam follower 338 is disposed on the cover pressure plate 332 and contacts the Z-axis guide seat 322 disposed on the fixed track plate 32.

[0036] The flexible tape high-precision transmission track structure of this solution is suitable for SMT flexible tape. First, the cam drive component 2 drives the Y-axis cam follower 337 to apply force to the fixed rail tie rod 335, so as to pull the cover plate mounting seat 331 to slide backward along the Y-axis guide rail 333. At the same time, the guide slope of the Z-axis guide seat 322 forces the Z-axis cam follower 338 to move upward, so as to drive the cover plate 332 to move upward along the Z-axis guide rail 334, so as to remove the cover plate 332 from the fixed edge track 321.

[0037] The tape is then introduced into the fixed-edge track 321, and the moving track component 4 adjusts the distance between itself and the fixed-edge track 321 according to the width of the tape.

[0038] Subsequently, the cam drive component 2 operates without applying force to the Y-axis cam follower 337. Under the tension of the fixed rail spring 336, the fixed rail tie rod 335 pushes the cover plate mounting seat 331 to slide forward along the Y-axis guide rail 333. At the same time, the Z-axis cam follower 338 moves down along the guide slope of the Z-axis guide seat 322 to drive the cover plate 332 to move down along the Z-axis guide rail 334 to press the cover plate 332 onto the fixed edge track 321 to prevent the flexible tape from shifting laterally or floating up and down during transmission.

[0039] Two guide rail components are installed on the guide rail bracket 31 to achieve bidirectional and unidirectional through-transmission of flexible tape. The flexible tape can enter from both ends of the track and move towards the middle of the track under the action of the two guide rail components. Alternatively, it can enter from one end of the track and be driven by the power source of the guide rail component at the other end to achieve unidirectional transmission through the entire track. In either transmission mode, the guide rail components dynamically apply lateral and vertical limiting forces to prevent the flexible tape from shifting laterally or floating up and down. This effectively solves the problems of uneven tension, insufficient positioning accuracy, and transmission stability of flexible tape in multidirectional transmission, and is especially suitable for automated production application scenarios of SMT chip taping.

[0040] In this embodiment, as Figure 3 , 4 As shown, the cover plate 332 has a Z-axis cam stroke groove on the side of the Z-axis cam follower 338, and the Z-axis guide seat 322 is provided corresponding to the Z-axis cam stroke groove. The Z-axis guide seat 322 has a guide slope whose height gradually increases from one end away from the cover plate mounting seat 331 toward the cover plate mounting seat 331.

[0041] Specifically, the moving rail component 4 is disposed on the front side of the fixed rail component 3, the first fixed rail assembly 33 and the second fixed rail assembly 34 are symmetrically disposed on the left and right ends of the fixed track plate 32, the cover plate 332 is located on the front side of the cover plate mounting seat 331, the Z-axis cam follower 338 is disposed in the middle of the cover plate 332, the height of the guide slope of the Z-axis guide seat 322 gradually decreases from back to front, and the Z-axis cam follower 338 is composed of a guide wheel seat and a guide wheel rotatably disposed on the guide wheel seat.

[0042] Specifically, there is a gap between the cover plate 332 and the fixed track plate 32, and a spring is provided between the cover plate 332 and the fixed track plate 32 to assist the Z-axis cam follower 338 in driving the cover plate 332 to move up and down along the Z-axis guide rail 334.

[0043] In this embodiment, as Figure 3 As shown, a limiting opening is provided on the side of the cover plate 332 near the moving rail component 4, and a limiting block 323 is provided on the fixed rail plate 32 at the position corresponding to the limiting opening.

[0044] Specifically, a limiting opening is provided on the front side of the cover plate 332 at the side of the Z-direction cam stroke groove, and a limiting block 323 is provided on the front side of the fixed track plate 32 and extends upward into the limiting opening to limit the forward movement range of the cover plate 332.

[0045] In this embodiment, as Figure 3 , 4As shown, a pressure roller 339 is slidably disposed on the side of the cover plate mounting base 331 near the moving rail component 4. The pressure roller 339 is located on the upper side of the cover plate 332. The pressure roller 339 includes a pressure roller seat 3391 and a pressure roller 3392 rotatably disposed on the pressure roller seat 3391. The cover plate 332 has a pressure passage corresponding to the position of the pressure roller 3392. A guide shaft seat is provided at each end of the pressure roller seat 3391. A guide post is inserted in the guide shaft seat. A pressure block is provided on the top of the two guide posts. The pressure block is connected to the pressure roller seat 3391 by a spring.

[0046] Specifically, the pressure roller 339 is disposed on the front side of the cover plate mounting seat 331. The pressure roller seat 3391 is slidably connected to the cover plate mounting seat 331 through the Z-guide rail 334. When the tape passes over the fixed-side track 321, when the Z-axis cam follower 338 moves down along the guide slope of the Z-axis guide seat 322 to drive the cover pressure plate 332 to move down along the Z-guide rail 334, the pressure roller seat 3391 moves down synchronously and is pressed down by the spring member to move the pressure roller 3392 down, partially passing through the pressure passage and contacting the tape.

[0047] In this embodiment, as Figure 5 As shown, the fixed rail bracket 31 is provided with a feeding assembly 35 on the lower side of the pressure roller 339. The feeding assembly 35 includes a feeding drive 351 and a feeding wheel 352. The feeding wheel 352 is rotatably disposed on the side of the fixed rail bracket 31 near the moving rail component 4. The feeding drive 351 is disposed on the side of the fixed rail bracket 31 away from the moving rail component 4, and its working end is connected to the feeding wheel 352. The fixed edge track 321 is provided with a feeding passage corresponding to the position of the feeding wheel 352. The feeding wheel 352 is at least partially located in the feeding passage.

[0048] Specifically, the first track fixing component 33 and the second track fixing component 34 have the same structure. A feeding component 35 is provided at each of the two working ends of the track fixing bracket 31. The feeding components 35 realize the bidirectional opposite transmission and unidirectional through transmission of flexible tape.

[0049] Specifically, the feeding wheel 352 is rotatably mounted on the front side of the fixed rail bracket 31 via a flange seat, and the feeding drive component 351 is a stepper motor, which is fixed on the rear side of the fixed rail bracket 31 to drive the feeding wheel 352 to rotate, so that the feeding wheel 352 passes through the feeding port and contacts the material belt when it rotates.

[0050] In this embodiment, as Figure 5As shown, the guide bracket 31 has a support component 36 on the side of the feeding assembly 35. The support component 36 includes a support fixing seat 361, a support driving member 362, a support push block 363, a support block 364, and a support top plate 365. The support fixing seat 361 is disposed on the guide bracket 31. The support push block 363 and the support block 364 are both slidably disposed on the support fixing seat 361. The support top plate 365 is disposed on the top of the support block 364 and is connected to the support push block 363 through the support block 364. The support driving member 362 is disposed at the lower part of the support fixing seat 361, and its working end is connected to the support push block 363.

[0051] Specifically, the support fixing seat 361 is disposed on the front side of the rail fixing bracket 31. The support driving member 362 drives the support push block 363 to move upward, so that the support block 364 carries the support top plate 365 upward to cooperate with the material channel and support the tape.

[0052] In this embodiment, as Figure 1 , 8 As shown, the moving rail component 4 includes a moving rail support 41, a moving rail base plate 42, a moving rail guide plate 43, a moving rail guide member 44, and a moving rail drive member 45. The moving rail support 41 is slidably mounted on the base plate 1 via the moving rail guide member 44. The moving rail drive member 45 is mounted on the base plate 1, and its working end is connected to the moving rail support 41. The moving rail base plate 42 is mounted on the moving rail support 41. The moving rail guide plate 43 is mounted on the moving rail base plate 42. A moving rail guide strip 46 is provided along the length of the moving rail guide plate 43 on the side of the moving rail guide plate 43 near the fixed rail plate 32.

[0053] Specifically, the moving rail support 41 is slidably mounted on the base plate 1 on the left and right sides by two moving rail guides 44. The moving rail drive 45 drives the moving rail guide plate 43 to move back and forth along the moving rail guides 44 by a screw drive, so as to adjust the width of the material channel according to the width of the material strip.

[0054] In this embodiment, as Figure 5 , 8 As shown, the fixed-side track bar 321 and the moving track guide bar 46 are respectively arranged on the lower part of the side of the fixed track plate 32 and the moving track guide plate 43 that are close to each other, so that the side of the fixed track plate 32 and the moving track guide plate 43 that are close to each other, together with the cover plate 332, forms a material channel.

[0055] Specifically, the lower front part of the fixed track plate 32 extends forward along its own length to form a fixed-edge track strip 321; the lower rear part of the moving track guide plate 43 extends backward along its own length to form a moving track guide strip 46. According to the width and thickness of the tape, the moving track drive member 45 drives the moving track guide plate 43 to move backward along the moving track guide member 44 by means of a lead screw, so that the moving track guide strip 46 is close to the fixed-edge track strip 321, and the Z-axis cam follower 338 moves down along the guide slope of the Z-axis guide seat 322 to drive the cover plate 332 to move down along the Z-axis guide guide member 334 to press the cover plate 332 onto the fixed-edge track strip 321, so that the tape can be transmitted in the material channel formed therein, which can avoid the tape from shifting laterally or floating up and down.

[0056] In this embodiment, as Figure 6 As shown, the cam drive component 2 includes a camshaft seat 21, a cam shaft 22, and a cam drive motor 23. The camshaft seat 21 is located on the side of the fixed rail bracket 31 away from the moving rail component 4. The cam shaft 22 is rotatably mounted inside the camshaft seat 21 and is parallel to the fixed-side rail 321. The cam drive motor 23 is located on the lower side of the base plate 1, and its working end is connected to the cam shaft 22. The cam shaft 22 is provided with a cover cam 24 to contact the Y-axis cam follower 337.

[0057] Specifically, there are two camshaft seats 21 located on the rear side of the guide bracket 31. The cam shaft 22 passes through the two camshaft seats 21. The cam drive motor 23 is a stepper motor that drives the cam shaft 22 to rotate via a linkage belt. The cam shaft 22 is provided with two cover plate cams 24, which respectively contact the Y-direction cam follower 337 of the first guide assembly 33 and the second guide assembly 34, so that the Y-direction cam follower 337 moves along the trajectory of the cover plate cam 24.

[0058] Specifically, the cam drive motor 23 drives the cam shaft 22 to rotate, causing the cover plate cam 24 to rotate. When the protrusion of the cover plate cam 24 contacts the Y-axis cam follower 337, it drives the Y-axis cam follower 337 to move backward, applying force to the fixed rail tie rod 335 to pull the cover plate mounting seat 331 to slide backward along the Y-axis guide rail 333. At the same time, the guide slope of the Z-axis guide seat 322 forces the Z-axis cam follower 338 to move upward, thereby driving the cover plate 332 to move upward along the Z-axis guide rail 334.

[0059] When the Y-axis cam follower 337 is misaligned with the protrusion of the cover plate cam 24, no force is applied to the Y-axis cam follower 337. Under the tension of the fixed rail spring 336, the fixed rail tie rod 335 pushes the cover plate mounting seat 331 to slide forward along the Y-axis guide rail 333. At the same time, the Z-axis cam follower 338 moves down along the guide slope of the Z-axis guide seat 322 to drive the cover plate 332 to move down along the Z-axis guide rail 334 to press the cover plate 332 onto the fixed edge track 321.
