Figure 2A for Figure 1A A schematic diagram of the tension adjustment module 200 of the conveying device 10 is shown. Figure 2B for Figure 2A A front view of the tension adjustment module 200.

[0016] like Figure 1A As shown, the conveying device 10 can convey a conveyed object, but the embodiments of the present invention are not limited thereto. The conveyed object is, for example, a finished or semi-finished electronic device, a material, a workpiece, etc. The conveying device 10 includes a driving mechanism 100 and at least one tension adjustment module (or detection module) 200. The driving mechanism 100 can convey the aforementioned electronic device forward to perform a corresponding process (for example, assembly, etc.), and the tension adjustment module 200 can automatically adjust the tension value applied by the driving mechanism 100 to the tension adjustment module 200 itself.

[0017] The embodiment of the utility model does not limit the installation position of the tension adjustment module 200, which can be configured at any position of the conveying medium 160 (described later). In addition, the embodiment of the utility model does not limit the number of tension adjustment modules 200 of the conveying device 10, which can be one or more than one. The conveying medium 160 is, for example, a belt.

[0018] like Figure 1A and 1B As shown, the driving mechanism 100 includes at least one driver 110, at least one driving belt 120, at least one first driving wheel 125A, at least one second driving wheel 125B, at least one first roller 130, at least one second roller 140, at least one third roller 150 and at least one conveying medium 160. The driver 110 is, for example, a motor. The first driving wheel 125A can be connected to the rotating shaft of the driver 110 so as to be driven by the driver 110 to rotate. The driving belt 120 connects the first driving wheel 125A and the second driving wheel 125B. When the rotating shaft of the driver 110 rotates, the first driving wheel 125A rotates, and the second driving wheel 125B is driven to rotate through the driving belt 120. The first roller 130 is connected to the second driving wheel 125B. When the second driving wheel 125B rotates, the first roller 130 is driven to rotate accordingly. The conveying medium 160 connects the first roller 130 and the second roller 140. The conveying medium 160 may rotate along with the rotation of the first roller 130 to convey the finished or semi-finished electronic device on the conveying medium 160 to a workstation.

[0019] like Figure 2A and 2B As shown, the conveying medium 160 can pass around one of the two second rollers 140, the third roller 150 and the other of the two second rollers 140. The tension adjustment module 200 is connected to the second roller 140 and the third roller 150. The third roller 150 can apply a pressing force FS to the conveying medium 160. Under the stop of the second rollers 140 on both sides, the conveying medium 160 generates a tension Ft on both sides of the third roller 150. The pressing force F S And tension F t The following formula (1) is satisfied, wherein the symbol f is the friction force between the roller and the belt, and the embodiment of the utility model does not limit the value of the friction force f.

[0020] F S =2×F t +f (1)

[0021] Please refer to Figure 3A , 3B , 4, 5 and 6, Figure 3A and 3B for Figure 2A Exploded views of the tension adjustment module 200 at different viewing angles. Figure 4 for Figure 2A The cross-sectional view of the tension adjustment module 200 along the direction 4-4' (first limit state), Figure 5 for Figure 4 The schematic diagram of the tension adjustment module 200 in the second limit state, and Figure 6 for Figure 4 A schematic diagram of the tension adjustment module 200 being in a state between the first limit state and the second limit state.

[0022] like Figure 3A and 3B As shown, the tension adjustment module 200 includes a first movable member 210, a carrier 220, an adjustment member 225, an elastic member 230, a limit rod 240 and an indicator 250. The first movable member 210 can withstand the tension of the conveying medium 160. The elastic member 230 is disposed between the first movable member 210 and the carrier 220. The position of the first movable member 220 changes based on the tension. In this way, the tension value of the conveying medium 160 or its change can be known through the position of the first movable member 220.

[0023] like Figure 3A , 3B As shown in Figures 4 and 5, the first movable member 210 includes a first sub-movable member 211 and a second sub-movable member 212. The first sub-movable member 211 and the second sub-movable member 212 are fixed to each other, for example, the first sub-movable member 211 and the second sub-movable member 212 are fixed to each other by at least one coupling member (not shown), wherein the coupling member is, for example, an element with a thread, such as a screw. The first movable member 210 and a roller can be fixed to each other. For example, the third roller 150 can be fixed to the first sub-movable member 211. The third roller 150 includes a fixed shaft 151 and a wheel body 152, and the wheel body 152 is pivotally connected to the fixed shaft 151 so as to be rotatable relative to the fixed shaft 151. The fixed shaft 151 can be fixed to the first sub-movable member 211. In addition, the first sub-movable member 211 has a limiting groove 211r, and the elastic member 230 includes a first end 231 and a second end 232. The first end 231 abuts against the bottom surface 211r1 of the limiting groove 211r.

[0024] In addition, the aforementioned pressing force FS is applied to the first movable member 210 by, for example, the elastic member 230 .

[0025] like Figure 3A and 3B As shown, the carrier 220 includes a stopper 221, a back plate 222, and a second movable member 223. The stopper 221 and the back plate 222 are fixed to each other. For example, the stopper 221 and the back plate 222 can be fixed to each other by at least one coupling member (not shown), wherein the coupling member is, for example, a threaded element, such as a screw. The back plate 222 can be fixed to the frame 11 of the conveying device 10 (the frame 11 is shown in FIG. 1 ). Figure 1A). The first movable member 210 is movably connected to the second movable member 223, for example, along the elastic force direction of the elastic member 230. The second movable member 223 can be fixed to the adjustment member 225. For example, the second movable member 223 and the adjustment member 225 can be fixed to each other by at least one coupling member (not shown), wherein the coupling member is, for example, a threaded element, such as a screw.

[0026] like Figure 3A , 3B As shown in Figures 4 and 5, the stopper 221 of the carrier 220 has a through hole 221a, a groove 221r, and an upper surface 221u and a lower surface 221b opposite to each other. The groove 221r ​​extends from the lower surface 221b to the upper surface 221u, but does not penetrate the stopper 221. The through hole 221a extends from the upper surface 221u to the groove 221r. The elastic member 230 abuts against the lower surface 221b of the stopper 221. The second end 232 of the elastic member 230 can abut against the groove bottom surface 221r1 of the groove 221r. There is a distance H1 between the bottom surface 211r1 of the limiting groove 211r of the first movable sub-member 211 and the groove bottom surface 221r1 of the groove 221r ​​of the carrier 220 along the Z axis, and the length of the elastic member 230 along the Z axis can be equal to the value of the distance H1.

[0027] like Figure 3A , 3B As shown in FIG. 4 , the back plate 222 has a through hole 222b, and at least a portion of the second movable member 223 and at least a portion of the first movable member 210 can be located in the through hole 222b. Due to the through hole 222b, when the first movable member 210 slides, it can avoid interference or collision with the solid material of the back plate 222.

[0028] like Figure 3A and 3B As shown, the second movable member 223 is slidably connected to the first movable member 210. In one embodiment, the first movable member 210 is, for example, a slider, and the second movable member 223 is, for example, a slide rail. For example, the second sub-movable member 212 of the first movable member 210 and the second movable member 223 can slide relative to each other. In addition, the major axis extension direction S1 of the second movable member 223 is substantially parallel to the Z axis. The second sub-movable member 212 has a slide groove 212r. The slide groove 212r of the second sub-movable member 212 is combined with the second movable member 223 to be relatively slidable. In addition, after the slide groove 212r of the second sub-movable member 212 is combined with the second movable member 223, the two only have the freedom to slide relative to each other along the Z axis.

[0029] like Figure 3A , 3BAs shown in Figures 4 and 5, by adjusting the position of the adjusting member 225, the position of the third roller 150 can be adjusted, thereby adjusting the tension of the conveying medium 160 applied to the third roller 150. For example, the adjusting member 225 and the first sub-movable member 211 are fixed to each other. When the adjusting member 225 and the first sub-movable member 211 move along the Z axis, the limiting rod 240 or the elastic member 230 can be driven, thereby driving the first movable member 210 to move along the Z axis. When the first movable member 210 moves along the Z axis, it also drives the third roller 150 to move along the Z axis (the fixed shaft 151 of the third roller 150 is fixed to the first movable member 210). The tension of the conveying medium 160 changes with the position of the third roller 150.

[0030] like Figure 3A and 3B As shown, the adjusting member 225 has at least one through hole 225a. At least one fixing member 260 can pass through the through hole 225a and be fixed in the fixing hole 222a of the back plate 222. In one embodiment, the fixing member 260 has, for example, a male thread, and the fixing hole 222a has, for example, a female thread. By screwing, the fixing member 260 can fix the relative position between the adjusting member 225 and the back plate 222. When the tension of the conveying medium 160 is to be adjusted, the fixing member 260 can be loosened so that the adjusting member 225 and the back plate 222 can move relative to each other. When the tension adjustment of the conveying medium 160 is completed, the fixing member 260 can be locked to fix the relative position between the adjusting member 225 and the back plate 222.

[0031] The elastic member 230 is, for example, a spring, such as a compression spring or a tension spring. Figure 4 As shown in FIG. 2 , the elastic member 230 may be in a free state (ie, not deformed), but may also have a deformation amount and store elastic potential energy. Figure 5 As shown in FIG. 1 , the compression amount (deformation amount) of the elastic member 230 is the largest, and the maximum elastic potential energy is stored.

[0032] like Figure 4As shown, the limiting rod 240 includes a rod body 241 and a limiting portion 242. The limiting portion 242 is connected to the rod body 241. The rod body 241 can pass through the through hole 221a and be fixed to the first sub-movable member 211 of the first movable member 210. For example, the end of the rod body 241 has a male thread, and the first sub-movable member 211 has a screw hole. By screwing the rod body 241 and the screw hole, the relative position between the limiting rod 240 and the first movable member 210 can be fixed. The upper surface 221u of the stopper 221 of the supporting member 220 is located between the limiting portion 242 and the groove bottom surface 221r1 of the groove 221r. In this way, when the stopper 221 moves along the +Z axis, it can push the limiting portion 242, thereby driving the limiting rod 240 and the first movable member 210 to move along the +Z axis. In addition, the through hole 221a has an inner diameter d1, and the limiting portion 242 has an outer diameter D1, which is larger than the inner diameter d1. Thus, the limiting portion 242 cannot be separated from the stopper 221 along the -Z axis.

[0033] like Figures 4 to 6 As shown, when the conveying medium 160 changes from a tight state to a tight state (tension increases), the third roller 150 moves in the +Z axis direction (for example, from Figure 6 The position changes to Figure 5 location, or from Figure 4 The position changes to Figure 5 position). Meanwhile, the elastic member 230 may exert a greater pressing force FS (elastic force) on the first movable member 210 to push the third roller 150 back in the -Z axis direction to tighten the conveying medium 160, thereby maintaining the preset tension (not limited to the value) of the conveying medium 160. The elastic member 230 may be selected according to the degree to which the conveying medium 160 needs to be adjusted, that is, the tension value of the conveying medium 160 may be automatically adjusted by the elastic member 230, for example, within the range of elastic force that the elastic member 230 can provide. In other embodiments, the default tension may be within the elastic force working range of the elastic member 230 (for example, the characteristic specification of the elastic member 230). In addition, the looser the conveying medium 160 is (the greater the tension drop is), the smaller the pressing force FS applied by the elastic member 230 to the first movable member 210 may be.

[0034] like Figures 4 to 6 As shown, when the conveying medium 160 changes from a tight state to a loose state (tension decreases), the third roller 150 tends to move toward the -Z axis direction. At this time, the elastic member 230 can drive the first movable member 210 to move toward the -Z axis direction to push the third roller 150 toward the -Z axis direction, thereby maintaining the preset tension (not limited to a numerical value) of the conveying medium 160. This default tension is within the elastic working range of the elastic member 230 (for example, the characteristic specifications of the elastic member 230).

[0035] like Figure 3AAs shown, the indicator 250 is connected to one end of the first movable member 210. For example, the indicator 250 includes a fixed portion 251 and a free end 252, wherein the fixed portion 251 can be fixed to the first sub-movable member 211 of the first movable member 210, and the free end 252 can pass through the through hole 222c of the back plate 222. The adjustment member 225 has a groove 225r, and the free end 252 can be arranged adjacent to the groove 225r. The indicator 250 can move along the Z axis with the first movable member 210, so the tension value or its change of the conveying medium 160 can be known from the position of the free end 252 relative to the groove 225r. In addition, although not shown, the surface 225s of the adjustment member 225 adjacent to the groove 225r can have at least one scale 2251, and the scales 2251 at different positions correspond to different tension values ​​of the conveying medium 160. The tension value or its change of the conveying medium 160 can be known through the corresponding relationship between the free end 252 of the indicator 250 and the scale 2251. In one embodiment, the indicator 250 is, for example, a pointer.

[0036] like Figure 3A As shown, the tension adjustment module 200 further includes a positioning member 270, which can be configured on the supporting member 220 and corresponds to the indicating member 250 in position. The positioning member 270 can be used to measure distance or position, for example, by using optical, magnetic, laser or other non-contact technologies for measurement. The positioning member 270 of this embodiment takes an optical ruler as an example, which can sense the position of the indicating member 250 and output a corresponding signal. This signal can be transmitted to an external electronic device (not shown) via wired or wireless technology. The external electronic device can display the corresponding tension value to monitor the tension value change of the conveying medium 160 online. For example, when the tension value of the conveying medium 160 exceeds a preset range, the external electronic device can output a warning signal (not shown).

[0037] In summary, the embodiments of the present invention provide a tension adjustment module, a detection module, and a conveying device using the same. The tension adjustment module or the detection module can adjust or detect the tension value of the conveying medium of the conveying device, and / or when the tension value of the conveying medium of the conveying device changes (for example, becomes loose or tight) during operation, the tension adjustment module can adaptively and automatically adjust the tension value of the conveying medium so that the tension value of the conveying medium is maintained at a preset value (not limited to the numerical range).

[0038] In summary, although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the attached patent application.
