[0043] See also Figure 1 In this embodiment, an automatic measuring machine 10 is provided, which is used to measure the electronic components 12 on the material belt 11 conveyed in the process of surface mounting technology (SMT) to detect whether the electronic components 12 are qualified. The automatic measuring machine 10 can automatically measure the electronic components 12 on the material belt 11, thereby realizing the automation of the detection of the electronic components 12, and can avoid manually tearing off the packaging film by passing the measuring needle 250 through the packaging film, thereby improving the purpose of production efficiency.

[0044] Please refer to Figure 1 and Figure 2 In this embodiment, a packaging film (not shown) for packaging electronic components 12 is provided on the material strip 11. The packaging film can package the electronic components 12 to prevent the electronic components 12 from being damaged by touch and oxidation. In addition, the material strip 11 is provided with a plurality of through holes 13 arranged along the extension direction of the material strip 11. At the same time, the arrangement direction of the plurality of electronic components 12 on the material strip 11 is also arranged along the extension direction of the material strip 11.

[0045] Please refer to Figure 1-Figure 3 The automatic value measuring machine 10 includes a feeder 300, a conveying platform 100 and a detection mechanism 200. The feeder 300 is connected to the conveying platform 100, and the feeder 300 is used to convey the material belt 11 equipped with electronic components 12 to the conveying platform 100. The conveying platform 100 is used to convey the material belt 11, so that the material belt 11 can move on a specified path, so as to facilitate the detection of the electronic components 12 on the material belt 11, and also to facilitate the removal of the electronic components 12 and installation on the printed circuit board. Optionally, in this embodiment, a conveying line 110 for conveying the material belt 11 is provided on the conveying platform 100, and the conveying platform 100 can convey the material belt 11 along the conveying path limited by the conveying line 110. The detection mechanism 200 can be movably disposed on the conveying platform 100, and the detection mechanism 200 is located above the conveying line 110, so that the detection mechanism 200 can move relative to the conveying platform 100 and selectively approach or move away from the conveying line 110, so that the detection mechanism 200 can measure the material belt 11 when it is close to the material belt 11, thereby realizing automatic measurement of the electronic components 12 on the material belt 11. It should be noted that in this embodiment, a measuring needle 250 is provided on the side of the detection mechanism 200 close to the conveying line 110, and the measuring needle 250 can pass through the packaging film used to package the material belt 11 and directly penetrate into the packaging film to contact the electronic components 12, and realize the measurement of the electronic components 12.

[0046] For further information, please refer to Figure 1 and Figure 4 The detection mechanism 200 includes a first measurement structure 230 , a second measurement structure 240 and a positioning structure 260 .

[0047] Among them, the first measuring structure 230 and the second measuring structure 240 can be movably installed on the conveying platform 100 and located above the conveying line 110. At the same time, the first measuring structure 230 and the second measuring structure 240 are arranged at intervals, and the first measuring structure 230 and the second measuring structure 240 are both provided with measuring needles 250 on the side close to the conveying line 110, so that the first measuring structure 230 and the second measuring structure 240 can measure the electronic components 12 respectively.

[0048] Optionally, the measuring needle 250 may include a first measuring needle 251 and a second measuring needle 252, wherein the first measuring needle 251 is used to detect the electronic component 12 of the first specification, and the second measuring needle 252 is used to detect the electronic component 12 of the second specification. Moreover, the first measuring needle 251 is installed on the first measuring structure 230, and the second measuring needle 252 is installed on the second measuring structure 240, so that the measuring needles 250 of different specifications can be detected respectively by the first measuring structure 230 and the second measuring structure 240. In other words, when detecting electronic components 12 of different specifications, the electronic components 12 of different specifications need to be placed under the corresponding first measuring structure 230 or the second measuring structure 240, respectively, so as to perform corresponding measurements by the first measuring structure 230 or the second measuring structure 240, thereby ensuring the accuracy and efficiency of the measurement of the electronic components 12.

[0049] It should be noted that, in the present embodiment, the first value measuring structure 230 and the second value measuring structure 240 can be set to multiple, and the value measuring needle 250 set on each first value measuring structure 230 and each second value measuring structure 240 can be used to measure electronic components 12 of different specifications. In other words, the value measuring needle 250 can also include a third value measuring needle for detecting electronic components 12 of the third specification, a fourth value measuring needle for detecting electronic components 12 of the fourth specification, and a fifth value measuring needle for detecting electronic components 12 of the fifth specification, and the third value measuring needle, the fourth value measuring needle and the fifth value measuring needle are respectively installed on multiple first value measuring structures 230 or second value measuring structures 240, so that each first value measuring structure 230 and each second value measuring structure 240 can measure electronic components 12 of different specifications, thereby realizing efficient and accurate measurement of electronic components 12 of multiple specifications, and greatly improving the measurement efficiency.

[0050] Optionally, in this embodiment, the number of the first measuring structure 230 is set to one, the number of the second measuring structure 240 is set to two, and the first measuring structure 230 is arranged between the two second measuring structures 240. The measuring needles 250 installed on the first measuring structure 230 and the two second measuring structures 240 can both measure electronic components 12 of different specifications. It should be understood that in other embodiments, the measuring needles 250 on the first measuring structure 230 and the two second measuring structures 240 can also be set to target electronic components 12 of the same specification, that is, the measuring needles 250 can be set according to actual needs. When only one specification of electronic components 12 needs to be measured, it is only necessary to set the measuring needles 250 for the electronic components 12 of this specification on the first measuring structure 230 and the two second measuring structures 240. When multiple specifications of electronic components 12 need to be measured, multiple corresponding measuring needles 250 are set and installed on the first measuring structure 230 or the two second measuring structures 240 respectively.

[0051] Furthermore, in this embodiment, the end of the measuring needle 250 close to the conveying line 110 is set as a wedge-shaped portion, so that the measuring needle 250 can penetrate the packaging film and extend into the packaging film to measure the electronic components 12 inside the packaging film, which can avoid the increase in time and cost caused by manually tearing off the packaging film, thereby reducing costs and improving measurement efficiency. It should be understood that in other embodiments, the end of the measuring needle 250 can also be set to other sharp shapes, such as a cone or a knife tip.

[0052] In addition, the positioning structure 260 is installed on the first measuring structure 230, and the first measuring structure 230 can drive the positioning structure 260 to move while moving relative to the conveying platform 100, and then when the first measuring structure 230 is close to the conveying line 110, the positioning structure 260 provides a positioning effect on the material belt 11, so that the electronic components 12 on the material belt 11 can maintain a stable position while measuring, so that the measurement of the electronic components 12 is efficient and stable. Optionally, in this embodiment, the positioning structure 260 can be inserted into the through hole 13 on the material belt 11 under the driving action of the first measuring structure 230, so as to provide a stable positioning effect for the material belt 11. It should be understood that in other embodiments, the positioning structure 260 can also provide a positioning effect on the material belt 11 in other ways. For example, the positioning structure 260 can press and hold the part of the material belt 11 where the electronic components 12 are not installed, so as to ensure the stability of the material belt 11.

[0053] Further, the positioning structure 260 includes a mounting frame 261, a first positioning tooth 264 and a second positioning tooth 265. The mounting frame 261 is mounted on the first measuring structure 230, and the mounting frame 261 extends below the second measuring structure 240. The first positioning tooth 264 and the second positioning tooth 265 are both convexly arranged on a side of the mounting frame 261 close to the conveyor line 110, and the first positioning tooth 264 is located below the first measuring structure 230, and the second positioning tooth 265 is located below the second measuring structure 240. The first positioning tooth 264 can provide a positioning function for the material belt 11 located below the first measuring structure 230, thereby ensuring that the first measuring structure 230 can ensure the stability of the electronic components 12 when detecting the electronic components 12 on the material belt 11 below the first measuring structure 230. Similarly, the second positioning teeth 265 can provide positioning for the material belt 11 located below the second measuring structure 240, thereby ensuring that the second measuring structure 240 can ensure the stability of the electronic components 12 when detecting the electronic components 12 on the material belt 11 below the second measuring structure 240. It should be noted that when the material belt 11 is being conveyed on the conveyor line 110, one end of the material belt 11 is located below the first measuring structure 230 and the other end is located below the second measuring structure 240. At this time, the first positioning teeth 264 and the second positioning teeth 265 can simultaneously provide positioning for the material belt 11, thereby ensuring the stability of the material belt 11. Among them, the number of the first positioning teeth 264 and the second positioning teeth 265 can be multiple, and similarly, the number of the first positioning teeth 264 and the second positioning teeth 265 can also be one.

[0054] Optionally, in this embodiment, since the second measuring structures 240 are provided on both sides of the first measuring structure 230, that is, the mounting frame 261 can extend in two directions and respectively extend to the bottom of the two second measuring structures 240, and second positioning teeth 265 are respectively provided under the two second measuring structures 240, thereby ensuring that when the material belt 11 is located under the second measuring structure 240, the corresponding second positioning teeth 265 can provide a stable positioning effect to the material belt 11.

[0055] In this embodiment, when the material belt 11 is conveyed to the bottom of the first measuring structure 230 and the electronic component 12 needs to be detected by the measuring needle 250 on the first measuring structure 230, the first measuring structure 230 is controlled to move toward the conveyor line 110, and the material belt 11 can be positioned by the first positioning tooth 264 to ensure the stability of the material belt 11, and then the electronic component 12 is measured by the measuring needle 250 on the first measuring structure 230, and the second measuring structure 240 may not take any action. Similarly, when the material belt 11 is conveyed to the bottom of the second measuring structure 240 and the electronic component 12 needs to be measured by the second measuring structure 240, the first measuring structure 230 is first controlled to move toward the conveyor line 110, and the second positioning teeth 265 are used to provide a positioning effect on the material belt 11 to ensure the stability of the material belt 11, and then the second measuring structure 240 is controlled to move toward the conveyor line 110 and measure the electronic component 12. It should be understood that at this time, the first measuring structure 230 and the second measuring structure 240 can also act simultaneously.

[0056] In addition, in other embodiments, the measuring needle 250 may be omitted from the first measuring structure 230 , that is, the first measuring structure 230 only provides a positioning function for the material strip 11 .

[0057] It should be noted that when the measuring needle 250 is installed on the first measuring structure 230 and the second measuring structure 240, it can pass through the mounting frame 261 and protrude from the side of the mounting frame 261 close to the conveyor line 110, so that the measuring needle 250 can pass through the mounting frame 261 and measure the electronic component 12 when the first measuring structure 230 or the second measuring structure 240 moves close to the conveyor line 110.

[0058] For further information, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6In this embodiment, the mounting frame 261 includes a connecting frame 262 and a first pressing plate 263. The connecting frame 262 is mounted on the first measuring structure 230, the first pressing plate 263 is mounted on the side of the connecting frame 262 close to the conveyor line 110, and the first pressing plate 263 extends to the bottom of the second measuring structure 240. It should be noted that in this embodiment, the connecting frame 262 is mounted on both sides of the first measuring structure 230, and the first pressing plate 263 is mounted on the connecting frame 262 located on both sides of the first measuring structure 230, thereby ensuring the installation stability of the first pressing plate 263, and at the same time, facilitating the installation of the measuring needle 250 on the first measuring structure 230, that is, installing the measuring needle 250 between the connecting frames 262 on both sides. The first positioning tooth 264 and the second positioning tooth 265 are both installed on the side of the first pressing plate 263 close to the conveyor line 110, that is, the first positioning tooth 264 is installed on the first pressing plate 263 located below the first measuring structure 230, and the second positioning tooth 265 is installed on the first pressing plate 263 located below the second measuring structure 240.

[0059] In this embodiment, the measuring needle 250 passes through the first pressing sheet 263 and enables the measuring needle 250 to measure the electronic component 12, thereby preventing the first pressing sheet 263 from affecting the detection of the electronic component 12. Optionally, a plurality of avoidance grooves 266 are provided on the first pressing sheet 263, and the plurality of avoidance grooves 266 are respectively provided corresponding to the plurality of measuring needles 250, wherein at least two avoidance grooves 266 respectively correspond to the first measuring structure 230 and the second measuring structure 240, thereby enabling the measuring needle 250 on the first measuring structure 230 to pass through the corresponding avoidance groove 266 to achieve the purpose of passing through the first pressing sheet 263, and at the same time enabling the measuring needle 250 on the second measuring structure 240 to pass through the corresponding avoidance groove 266 to achieve the purpose of passing through the first pressing sheet 263. It should be noted that the avoidance groove 266 can be directly opened through the first pressing plate 263, and the first pressing plate 263 can also be set to a broken line shape or a curve shape, etc. In this case, the recessed part of the first pressing plate 263 forms the avoidance groove 266.

[0060] Furthermore, in this embodiment, the length of the measuring needle 250 protruding from the first pressing plate 263 through the avoidance groove 266 is less than the length of the first positioning tooth 264 protruding from the first pressing plate 263, and is less than the length of the second positioning tooth 265 protruding from the first pressing plate 263. This allows the measuring needle 250 to measure the electronic component 12 on the material strip 11 when the first positioning tooth 264 and the second positioning tooth 265 pass through the through hole 13 and provide positioning for the material strip 11.

[0061] In addition, the detection mechanism 200 also includes at least two needle lowering mechanisms 210 and at least two replacement structures 220. Both needle lowering mechanisms 210 can be movably installed on the conveying platform 100, and the two needle lowering mechanisms 210 are arranged at intervals, and both needle lowering mechanisms 210 can move relative to the conveying platform 100 to selectively approach the conveying line 110 or move away from the conveying line 110. The two replacement structures 220 are detachably installed on the two needle lowering mechanisms 210, respectively, and the first measurement structure 230 and the second measurement structure 240 are respectively installed on the two replacement structures 220, so that the first measurement structure 230 and the second measurement structure 240 can be disassembled and replaced through the detachable connection between the replacement structure 220 and the needle lowering mechanism 210.

[0062] It should be noted that the replacement structure 220 can be a block that is connected to the needle lowering mechanism 210, and the needle lowering mechanism 210 is provided with a slot corresponding to the block, and the block can be inserted into the slot to realize the detachable connection between the needle lowering mechanism 210 and the replacement structure 220, or the replacement structure 220 can be a part made of magnetic parts, which can be detachably installed on the needle lowering mechanism 210 by magnetic adsorption.

[0063] Please refer to Figure 1 , Figure 7 , Figure 8 and Fig. 9 The conveyor line 110 includes a conveyor trough 120 extending in a straight line, the conveyor trough 120 is opened on the conveyor platform 100, and the conveyor trough 120 is used to convey the material belt 11. It should be understood that in other embodiments, the extension path of the conveyor trough 120 can also be a curve or a broken line. In this case, the first measurement structure 230 and the second measurement structure 240 in the detection mechanism 200 need to be arranged according to the conveying path of the conveyor trough 120, so that the detection mechanism 200 can measure the electronic components 12 on the material belt 11 on the conveyor trough 120 when moving relative to the conveyor line 110.

[0064] Please refer to Figure 1 and Fig.10 The feeder 300 is disposed at one end of the conveying trough 120 so that the feeder 300 can convey the material belt 11 along the conveying trough 120. It should be noted that the feeder 300 includes a conveying gear 310, which is rotatably connected to the conveying platform 100, and the conveying gear 310 is provided with a plurality of gear teeth 311 adapted to the through hole 13. When the material belt 11 is placed inside the conveying trough 120, at least one gear tooth 311 extends into the through hole 13, and conveys the material belt 11 along the conveying trough 120 during the rotation of the conveying gear 310.

[0065] In addition, a cutting device 400 is provided at the other end of the conveying trough 120, and the cutting device 400 is used to cut off the material strip 11 corresponding to the electronic component 12 that has completed the measurement, thereby ensuring the subsequent production to continue. It should be understood that in other embodiments, the setting of the cutting device 400 can also be cancelled.

[0066] Furthermore, in the present embodiment, a second pressing sheet 122 is also provided inside the conveying trough 120, and a conveying space 121 for conveying the material belt 11 is formed between the second pressing sheet 122 and the bottom wall of the conveying trough 120. That is, in the present embodiment, the second pressing sheet 122 is substantially parallel to the bottom wall of the conveying trough 120, so that a conveying space 121 adapted to the material belt 11 can be defined between the second pressing sheet 122 and the bottom wall of the conveying trough 120, which can ensure the stable conveying of the material belt 11 inside the conveying space 121, avoid the material belt 11 from warping or deviation, and thus ensure that the electronic components 12 on the material belt 11 can be provided with stable and efficient measurement values. In addition, a positioning opening adapted to the positioning structure 260 is also provided on the second pressing sheet 122, so that when the positioning structure 260 moves close to the material belt 11, it can pass through the positioning opening and penetrate into the through hole 13 on the material belt 11, thereby realizing the positioning effect on the material belt 11.

[0067] It should be noted that in this embodiment, an installation groove 123 adapted for the second pressing plate 122 is provided on the side wall of the conveying groove 120. The second pressing plate 122 is installed in the conveying groove 120 through the installation groove 123, which enables the second pressing plate 122 to provide a stable pressing effect on the material belt 11, thereby ensuring that the material belt 11 can be stably conveyed.

[0068] In addition, in this embodiment, the automatic value measuring machine 10 may also include a control system (not shown), a driving device (not shown) and a value measuring instrument (not shown). Among them, detection devices (not shown) may be provided at both ends of the conveying trough 120 to detect the input and output of the material belt 11, that is, when the material belt 11 is placed into the end of the conveying trough 120 close to the feeder 300, the detection device detects the placement of the material belt 11, and at this time, the control system controls the driving device connected to the feeder 300 to convey the material belt 11 at a fixed distance, so as to convey the material belt 11 to the specified position. When the material strip 11 is conveyed to the designated position, the through hole 13 control system controls the driving device connected to the detection mechanism 200 to drive the first measuring structure 230 to move close to the conveyor line 110, and the position calibration of the material strip 11 can be achieved through the cooperation of the positioning structure 260 and the through hole 13, which can improve the position accuracy of the material strip 11, and then the measuring needle 250 on the first measuring structure 230 can be used to contact the electronic component 12 for measurement, or the second measuring structure 240 can be driven by the driving device to move close to the conveyor line 110 and the measuring needle 250 can be used to contact the electronic component 12 for measurement. The measuring instrument can be electrically connected to the measuring needle 250, so that the measuring instrument can measure the electronic component 12 through the contact between the measuring needle 250 and the electronic component 12, and the data can be read on the measuring instrument.

[0069] Among them, the control system can be a PLC control unit. The detection device can be a photosensitive sensor such as infrared or laser. In addition, the measuring needle 250 can send a control instruction to a host computer (not shown) by connecting to a wired cable such as USB, serial port, network cable, Bluetooth, WiFi, etc. or wirelessly, and the host computer obtains the measured value through a measuring instrument such as an LCR meter, a multimeter, an impedance analyzer, an oscilloscope, a network analyzer, a comprehensive tester, etc. connected by a wired cable such as USB, serial port, GPIB, network cable, WiFi, etc. or wirelessly.

[0070] In summary, the automatic value measuring machine 10 provided in this embodiment can move relative to the conveying platform 100 through the detection mechanism 200, and at the same time drive the value measuring needle 250 to approach or move away from the conveying line 110, so that the value measuring needle 250 can measure the electronic components 12 on the material belt 11 conveyed by the conveying line 110 when the value measuring needle 250 approaches the conveying line 110, and then the value measuring machine 10 can automatically measure and detect the electronic components 12 on the material belt 11, thereby avoiding the errors caused by manual detection and improving the efficiency of the value measuring. In addition, by measuring the electronic components 12 through the packaging film by the value measuring needle 250, the waste of time cost caused by manually tearing off the packaging film can be avoided, further improving the production efficiency.
