DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0022] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0023] Such as Figures 1 to 3As shown in the figure, a tape feeding device includes a base 100, a reel placing assembly 200, a first guiding structure 300, a second guiding structure 400, an adjusting structure 500, and a pressing structure 600.

[0024] As Figures 1 to 3 shown in the figure, a tape feeding device includes:

[0025] A base 100, on which a reel placing assembly 200 for installing a tape reel 700 is provided;

[0026] A guiding assembly, which is provided on the base 100 and includes a first guiding structure 300 and a second guiding structure 400. The tape 710 of the tape reel 700 is movably clamped on the first guiding structure 300 and the second guiding structure 400. An adjusting structure 500 is movably provided between the first guiding structure 300 and the second guiding structure 400, and the adjusting structure 500 has a first moving position. When the adjusting structure 500 is in the first moving position, the tape 710 between the first guiding structure 300 and the second guiding structure 400 can be stretched, thereby realizing the tension adjustment of the tape 710, avoiding the breakage of the tape 710 during pulling due to being too tight, and effectively improving the stability and smoothness of the feeding.

[0027] Specifically, as Figures 1 to 3 shown in the figure, in this embodiment, the base 100 includes a rectangular bottom plate 110 and a support plate 120 vertically provided on the bottom plate 110, and the support plate 120 is detachably connected to the bottom plate 110 for the user to install and maintain.

[0028] In this embodiment, a reel placing assembly 200 is arranged at the top of the support plate 120. The reel placing assembly 200 includes a turntable frame 210 for installing a tape reel 700. The turntable frame 210 includes a fixing part 211 clamped with the tape reel 700, and a telescopic elastic member 212 is provided on the fixing part 211. When the tape reel 700 is clamped on the fixing part 211, the elastic member 212 abuts against the tape reel 700. By providing a telescopic elastic member 212 on the fixing part 211, the tape reel 700 can be quickly clamped on the fixing part 211 in a pushing manner, effectively improving the convenience and efficiency of installing the tape reel 700.

[0029] In this embodiment, the reel placing assembly 200 includes a third support shaft 220 detachably and vertically provided on the support plate 120. The turntable frame 210 is rotatably arranged on the third support shaft 220, and a plurality of elastic members 212 are provided and arranged circumferentially along the fixing part 211 to ensure the uniformity of the clamping between the fixing part 211 and the tape reel 700, thereby ensuring the stability of the turntable frame 210 during rotation.

[0030] In this embodiment, the elastic member 212 is strip-shaped and extends along the length direction of the fixing portion 211. One side of it is clamped in the fixing portion 211, and the other side protrudes out of the fixing portion 211. Moreover, inclined edges are provided at both ends of the elastic member 212 to avoid that the tape roll 700 can be smoothly sleeved on the fixing portion 211 and abuts against the elastic member 212.

[0031] In order to guide the tape 710 in the tape roll 700 to the use position, in this embodiment, a guiding assembly is further included, which is arranged below the material tray placing assembly 200 and is detachably connected to the supporting plate 120. The guiding assembly includes a first guiding structure 300 and a second guiding structure 400, which are used to form guiding and limiting for the tape 710 in the tape roll 700 and guide the tape 710 to move stably towards the use position.

[0032] In order to adjust the tension of the tape 710, in this embodiment, an adjusting structure 500 is movably arranged between the first guiding structure 300 and the second guiding structure 400. The adjusting structure 500 has a first moving position. When the adjusting structure 500 is in the first moving position, it can stretch the tape 710 between the first guiding structure 300 and the second guiding structure 400, so that this section of the tape 710 is in a relaxed state, effectively avoiding the risk of the tape 710 breaking due to being too tight during subsequent pulling, and at the same time improving the smoothness of the tape 710 during pulling.

[0033] In this embodiment, the adjusting structure 500 includes a movable member 510 and a first driving member 520. The movable member 510 has a first initial position and a first moving position. The first driving member 520 drives the movable member 510 to move between the first initial position and the first moving position. When the movable member 510 is in the first moving position, the length of the tape 710 between the first guiding structure 300 and the second guiding structure 400 is greater than the straight-line distance between the first guiding structure 300 and the second guiding structure 400. By controlling the movement of the movable member 510 through the first driving member 520, precise automatic control of the tension of the tape 710 is realized, the risk of the tape 710 breaking is avoided, the service life of the tape 710 is extended, and at the same time the stability of the material supply is ensured.

[0034] In this embodiment, when the movable member 510 is in the first initial position, the movable member 510 is separated from the tape 710 and is above the tape 710.

[0035] Preferably, in this embodiment, the first driving member 520 and the movable member 510 are arranged in sequence from top to bottom and are longitudinally aligned. The first driving member 520 is detachably connected to the supporting plate 120, and the movable member 510 is arranged at the output end of the first driving member 520.

[0036] In this embodiment, the movable member 510 includes a movable frame 511 connected to the output end of the first driving member 520, and a second roller 512 rotatably disposed on the movable frame 511. A third groove 513 adapted to the width of the tape 710 is provided on the second roller 512. Through the rotatable design of the second roller 512, the tape 710 can move more smoothly during the feeding process. And the design of the third groove 513 can further limit the tape 710, avoiding the tape 710 from shifting during the movement, effectively ensuring the stability of the tape 710 feeding.

[0037] Preferably, in this embodiment, the third groove 513 extends along the circumferential direction of the second roller 512.

[0038] In this embodiment, the first driving member 520 is a driving cylinder or a hydraulic cylinder or a driving motor. Preferably, the first driving member 520 is a driving cylinder.

[0039] In this embodiment, the first guiding structure 300 and the second guiding structure 400 are arranged in an up-and-down staggered manner, and there is a gap for accommodating the adjusting structure 500 between the first guiding structure 300 and the second guiding structure 400, which can prevent the adjusting structure 500 from interfering with the first guiding structure 300 and the second guiding structure 400.

[0040] In this embodiment, the first guiding structure 300 includes a first support shaft 310 detachably and perpendicularly connected to the support plate 120, and two sets of snap rings 320 detachably disposed on the first support shaft 310. There is a gap for accommodating the tape 710 between the two sets of snap rings 320, and the snap rings 320 cooperate with the gap to form a first groove 321 adapted to the width of the tape 710, so as to limit the tape 710 on the first guiding structure 300, avoiding the tape 710 from shifting during the movement, effectively ensuring the stability of the tape 710 feeding.

[0041] Preferably, in this embodiment, the first support shaft 310 is detachably connected to the support plate 120 through a connecting handle 330.

[0042] In this embodiment, the second guiding structure 400 includes a second support shaft 410 detachably and perpendicularly connected to the support plate 120, and a first roller 420 rotatably disposed on the second support shaft 410. A second groove 421 adapted to the width of the tape 710 is provided on the first roller 420. Through the rotatable design of the first roller 420, the tape 710 can move more smoothly during the feeding process. And the design of the second groove 421 can further limit the tape 710, avoiding the tape 710 from shifting during the movement, effectively ensuring the stability of the tape 710 feeding.

[0043] To prevent the tape 710 from detaching from the second guiding structure 400 when adjusting the tension, in this embodiment, a pressing structure 600 is further provided. The pressing structure 600 is movably disposed above the second guiding structure 400, and the pressing structure 600 has a second moving position. When the pressing structure 600 is in the second moving position, the pressing structure 600 abuts against the tape 710 on the second guiding structure 400. The tape 710 is stretched via the first guiding structure 300, avoiding the retraction phenomenon caused by the tape 710 detaching from the second guiding structure 400, and effectively ensuring the stability of the tape 710 feeding.

[0044] It should be noted that the abutting force of the pressing structure 600 is greater than the pulling force when the adjusting structure 500 moves and less than the pulling force when the tape 710 is in use.

[0045] In this embodiment, the pressing structure 600 includes a pressing member 610 and a second driving member 620. The pressing member 610 has a second initial position and a second moving position. The second driving member 620 drives the pressing member 610 to move between the second initial position and the second moving position. When the pressing member 610 is in the second moving position, the pressing member 610 abuts against the tape 710 on the second guiding structure 400, avoiding the tape 710 from slipping out of the second guiding structure 400 under the pulling of the adjusting structure 500. By controlling the movement of the pressing member 610 through the second driving member 620, the pressing member 610 can accurately press the tape 710 when needed, improving the accuracy and reliability of position control.

[0046] In this embodiment, the pressing member 610 is a rolling wheel rotatably connected to the output end of the second driving member 620, and its size is adapted to the size of the second groove 421.

[0047] In this embodiment, the second driving member 620 is a sliding structure or a driving cylinder or a hydraulic cylinder or a driving motor. Preferably, the second driving member 620 is a sliding structure.

[0048] In this embodiment, the sliding structure includes a sliding seat 621 detachably connected to the support plate 120, and a sliding block 622 movably disposed on the sliding seat 621. A spring 623 is provided between the sliding block 622 and the sliding seat 621. The pressing member 610 is rotatably disposed at one end of the sliding block 622 away from the spring 623. When the pressing member 610 is in the second initial position, the pressing member 610 abuts against the second groove 421, and the user can move the pressing member 610 between the second initial position and the second moving position by manually pulling the sliding block 622.
