[0036] Please refer to Figure 1 and Figure 2 An embodiment of the present invention provides a sampling device, including a base 10, a cutting mechanism 20 and a moving mechanism 30.

[0037] Combination Figures 3 to 5 As shown, the cutting mechanism 20 includes an L-shaped cutting base 21, a driving member 22, and a cutter 23. One end of the cutting base 21 is located at the top of the base 10, and the other end of the cutting base 21 is provided with the driving member 22. The cutter 23 is located below the other end of the cutting base 21 and connected to the output end of the driving member 22. The driving member 22 is used to drive the cutter 23 to move up and down, and the cutter 23 is used to cut the substrate. The moving mechanism 30 includes a longitudinal moving plate 31, a transverse moving plate 32, and a sampling pad 33. The longitudinal moving plate 31 is slidably disposed at the top of the base 10 and can move longitudinally relative to the base 10. The transverse moving plate 32 is slidably disposed at the top of the longitudinal moving plate 31 and can move transversely relative to the base 10. The sampling pad 33 is located below the cutter 23 and disposed at the top of the transverse moving plate 32. The sampling pad 33 is used to support the substrate.

[0038] In this invention, "longitudinal" refers to the front-to-back direction, and "lateral" refers to the left-to-right direction.

[0039] Specifically, the sampling process for the coated substrate is as follows: the coated substrate is placed on top of the sampling pad 33. By moving the transverse moving plate 32 laterally, the sampling pad 33 and the substrate can be moved laterally. When each sampling position in the length direction of the substrate moves to below the cutter 23, the cutter 23 is driven downward by the driving component 22 to cut the substrate, thus obtaining a sample piece in the length direction of the substrate. After one cut is completed, the cutter 23 is driven upward by the driving component 22 to the initial position, thus realizing the sampling in the length direction of the substrate. Sampling: Since the longitudinal moving plate 31 is slidably mounted on the top of the base 10, the transverse moving plate 32 moves longitudinally. Under the action of the longitudinal moving plate 31, the sampling pad 33 and the substrate can be moved longitudinally. When each sampling position in the width direction of the substrate moves to below the cutter 23, the cutter 23 is driven downward by the drive component 22 to cut the substrate, thus obtaining a sample piece in the width direction of the substrate. After cutting, the cutter 23 is driven upward by the drive component 22 to the initial position, thus realizing sampling in the width direction of the substrate. The sample piece will then be measured and analyzed to obtain the quality of the coated substrate.

[0040] This invention is easy to operate. The moving mechanism 30 facilitates the movement of the substrate in both the horizontal and vertical directions, so that each sampling position in the length and width directions of the substrate is moved to the underside of the cutter 23 of the cutting mechanism 20. This allows the cutter 23 of the cutting mechanism 20 to automatically cut the substrate. Compared with existing methods, this invention can automatically cut the substrate, saving time and effort, reducing manual labor intensity, and improving sampling efficiency.

[0041] In this embodiment, the other end of the cutting base 21 is provided with a mounting groove 21a, which communicates with the interior of the cutting base 21. The bottom of the other end of the cutting base 21 is provided with a mounting seat 211, and the top of the other end of the cutting base 21 is provided with a drive component protective cover 212. The bottom and one side of the drive component protective cover 212 are open, and the mounting groove 21a communicates with the interior of the drive component protective cover 212. The drive component 22 is located within the mounting groove 21a and the drive component protective cover 212 and is positioned at the top of the mounting seat 211. The other end of the cutting base 21 and one side of the drive component protective cover 212 are provided with a first sealing plate 213 for closing the opening on one side of the drive component protective cover 212 and the groove of the mounting groove 21a. The cutter 23 is located below the mounting seat 211, and the output end of the drive component 22 passes through the through hole 2112 of the mounting seat 211 and connects to the cutter 23. The mounting base 211 provides mounting support for the drive component 22, and the drive component protective cover 212 and the first sealing plate 213 protect the drive component 22 and prevent damage to the drive component 22.

[0042] In this embodiment, the top of the mounting base 211 is provided with a mounting base groove 2111, and the driving member 22 is provided at the bottom of the mounting base groove 2111.

[0043] The cutter 23 and the mounting base 211 are housed within a cutter protective cover 214, which is connected to the other end of the cutting base 21. The cutter protective cover 214 has openings at its top, bottom, and one side. A second sealing plate 215 is sandwiched between the first sealing plate 213 and one inner wall of the cutter protective cover 214. The cutter protective cover 214 and the second sealing plate 215 protect the cutter 23 and the mounting base 211, preventing damage to the cutter 23.

[0044] In this embodiment, the top of the cutter protective cover 214 has two mounting portions 2141, and the two mounting portions 2141 are respectively connected to the two sides of the other end of the cutting base 21.

[0045] The drive component 22 is preferably a cylinder.

[0046] Combination Figures 4 to 8 As shown, the cutter 23 includes a circular cutter head 231, a connecting seat 232, and a flange 233. The connecting seat 232 is located at the bottom end of the flange 233 and has a mounting cavity. The cutter head 231 is interference-fitted with the mounting cavity, and a portion of the cutter head 231 protrudes from the bottom end of the connecting seat 232. The flange 233 is connected to the output end of the drive component 22. Specifically, the flange 233 is fitted onto the outer periphery of the output end of the drive component 22 through its flange mounting hole 2331. The drive component 22 drives the flange 233 to move up and down, thereby driving the connecting seat 232 and the cutter head 231 to move up and down. By moving the cutter head 231 downward, the substrate can be cut. The sample piece obtained after cutting the substrate by the cutter head 231 is circular in shape. In practical applications, the portion of the cutter head 231 protruding from the bottom end of the connecting seat 232 is greater than the thickness of the substrate.

[0047] In this embodiment, the connecting seat 232 includes a first semicircular ring 2321 and a second semicircular ring 2322. The first semicircular ring 2321 and the second semicircular ring 2322 are arranged opposite to each other, and the mounting cavity is formed between the inner circumferential surfaces of the first semicircular ring 2321 and the second semicircular ring 2322. The first end of the first semicircular ring 2321 is provided with a first mounting hole 23211 and a first groove, and the first mounting hole 23211 extends to the outer circumferential surface of the first semicircular ring 2321. The first end of the second semicircular ring 2322 is provided with a second mounting hole 23221 and a first protrusion 23222, and the second mounting hole 23221 extends to the outer circumferential surface of the second semicircular ring 2322. The first protrusion 23222 cooperates with the first groove. A first fastener 2323, such as a screw, is installed in the second mounting hole 23221 and the first mounting hole 23211. The second end of the first semicircular ring 2321 is provided with a second protrusion 23212, and the second end of the second semicircular ring 2322 is provided with a second groove 23223. The second protrusion 23212 and the second groove 23223 cooperate with each other. The second protrusion 23212 is provided with a third mounting hole, in which a pin 2324 is installed. The bottom inner wall of the second groove 23223 is provided with a fourth mounting hole 23224, which extends to the bottom of the second semicircular ring 2322. The bottom of the flange 233 is provided with a fifth mounting hole 2332, which extends to the top of the flange 233. The two ends of the pin 2324 extend from the bottom and top of the third mounting hole and respectively engage with the fourth mounting hole 23224 and the fifth mounting hole 2332. The second semicircular ring 2322 is provided with a first hole 23225, and the bottom end of the flange 233 is provided with a second hole. Second fasteners 2325, such as screws, are installed in the second hole and the first hole 23225. The number of the first hole 23225 and the second hole can be set according to the actual situation.

[0048] With the above structure, the cutting head 231 can be quickly replaced after wear. When replacing the cutting head 231, first remove the first fastener 2323 from the first mounting hole 23211 and the second mounting hole 23221. Then, rotate the first semi-circular ring 2321 around the pin 2324, causing the first groove of the first semi-circular ring 2321 and the first protrusion 23222 of the second semi-circular ring 2322 to separate. At this point, the inner circumferential surface of the first semi-circular ring 2321 separates from the cutting head 231. Then, remove the cutting head 231 and place the new cutting head 231 inside the second semi-circular ring 2322, ensuring the outer circumferential surface of the cutting head 231 is flush with the second semi-circular ring 2322. The inner circumferential surfaces of the semicircular ring 2322 are brought into contact. Then, the first semicircular ring 2321 is rotated in the opposite direction around the pin 2324 to the initial position, so that the first groove of the first semicircular ring 2321 and the first protrusion 23222 of the second semicircular ring 2322 are engaged. Then, the first fastener 2323 is reinstalled in the first mounting hole 23211 and the second mounting hole 23221, and the outer circumferential surface of the cutter head 231 abuts against the inner circumferential surface of the first semicircular ring 2321 and the inner circumferential surface of the second semicircular ring 2322. Thus, the replacement of the cutter head 231 is completed.

[0049] With the above structure, the cutter head 231 and the connecting seat 232 can also be replaced as a whole. During replacement, first remove the second fastener 2325 from the first hole 23225 and the second hole. Then pull down the cutter head 231 and the connecting seat 232 to separate the pin 2324 from the fifth mounting hole 2332 of the flange 233. Then place the new cutter head 231 and the connecting seat 232 at the bottom of the flange 233 and insert one end of the pin 2324 of the new connecting seat 232 into the fifth mounting hole 2332 of the flange 233. Then reinstall the second fastener 2325 in the first hole 23225 and the second hole. In this way, the replacement of the cutter head 231 and the connecting seat 232 as a whole is completed.

[0050] Furthermore, the bottom end of the cutter head 231 is provided with a mounting position 2311, and an EVA (Ethylene-Vinyl Acetate Copolymer Resin) foam component 234 (see...) is provided inside the mounting position 2311. Figure 5The EVA foam component 234 protrudes from the bottom end of the cutter head 231. In this embodiment, the EVA foam component 234 is mounted at the bottom of the mounting position 2311 by screws or the like. When the cutter head 231 moves downward, it can drive the EVA foam component 234 downward. When the EVA foam component 234 contacts the substrate, as the cutter head 231 continues to move downward, the EVA foam component 234 is compressed under the pressure of the substrate. At this time, the EVA foam component 234 can hold the substrate in place, which facilitates the cutting of the substrate by the cutter head 231, helps in sample sheet formation, and reduces the wear of the cutter head 231. After sampling, when the cutter head 231 moves upward, it can drive the EVA foam component 234 upward. When the EVA foam component 234 separates from the substrate, it can return to its original position because it is no longer compressed by the substrate. Using the EVA foam component 234 is low-cost and easy to manufacture.

[0051] In an alternative embodiment, a metal component is provided within the mounting position 2311, with a portion of the metal component protruding from the bottom end of the cutting head 231. The metal component and the bottom of the mounting position 2311 are connected by an elastic element, preferably a spring. The metal component is, for example, a stainless steel component, and the number of elastic elements can be set according to actual conditions. When the cutting head 231 moves downwards, driving the elastic element and the metal component, the substrate will compress the metal component when the metal component contacts the substrate. At this time, the elastic element compresses and applies a restoring force to the metal component. In this way, the substrate can be pressed down by the metal component, which facilitates the cutting head 231 in cutting the substrate, helps in sample forming, and reduces the wear of the cutting head 231. After sampling, when the cutting head 231 moves upwards, it can drive the metal component and the elastic element upwards. When the metal component separates from the substrate, the restoring force of the elastic element can drive the metal component downwards to the initial position.

[0052] Combination Figures 9 to 12 As shown, a longitudinal moving plate 31 is slidably disposed at the top of the base 10, and a transverse moving plate 32 is slidably disposed at the top of the longitudinal moving plate 31. Specifically, the top of the base 10 is provided with a first guide rail 311, which extends longitudinally.

The bottom end of the first limiting plate 34 is connected to the top end of the base 10 via a first connecting plate 341. The first limiting plate 34 and the first connecting plate 341 form an L-shaped structure. The first connecting plate 341 provides mounting support for the first limiting plate 34. A plurality of first positioning grooves 342 are provided on the side of the first limiting plate 34 near the longitudinal moving plate 31, and these first positioning grooves 342 are spaced apart longitudinally. The length direction of the first positioning grooves 342 is the same as the height direction of the first limiting plate 34. The distance between two adjacent first positioning grooves 342 is the same as the distance between two adjacent first bearings 314. The first bearings 314 are used to cooperate with the first positioning grooves 342. When the sampling pad 33 drives the longitudinal moving plate 31 to move longitudinally, the longitudinal moving plate 31 can drive the first slider 313 and a number of first bearings 314 to move longitudinally. When the first bearing 314 moves to a position corresponding to one of the first positioning grooves 342, the first bearing 314 can cooperate with the first positioning groove 342. By cooperating with the first positioning groove 342, the movement of the longitudinal moving plate 31 can be positioned, which facilitates the cutter 23 to cut the substrate and enables fixed-distance sampling in the width direction of the substrate.

[0054] In this embodiment, there are five first bearings 314 and six first positioning grooves 342. Understandably, the number of first bearings 314 and first positioning grooves 342 can be set according to actual conditions.

A plurality of second bearings 324 are provided on the side of the second slider 323 away from the transverse moving plate 32. The plurality of second bearings 324 are spaced laterally.

The distance between two adjacent second positioning grooves 352 is the same as the distance between two adjacent second bearings 324. The second bearings 324 are used to cooperate with the second positioning grooves 352. When the sampling pad 33 drives the transverse moving plate 32 to move laterally, the transverse moving plate 32 can drive the second slider 323 and several second bearings 324 to move laterally. When the second bearing 324 moves to a position corresponding to one of the second positioning grooves 352, the second bearing 324 can cooperate with the second positioning groove 352. By cooperating with the second positioning groove 352, the movement of the transverse moving plate 32 can be positioned, which facilitates the cutter 23 to cut the substrate and enables fixed-distance sampling in the length direction of the substrate.

[0056] In this embodiment, there are eleven second bearings 324 and four second positioning slots 352. Understandably, the number of second bearings 324 and second positioning slots 352 can be set according to actual conditions.

[0057] Both the first bearing 314 and the second bearing 324 are plastic bearings. The first slider 313 has several first slots on the side away from the longitudinal moving plate 31, each first slot corresponding to a first bearing 314. The first bearing 314 is housed in the corresponding first slot and fitted onto the outer circumference of the first rotating shaft. A portion of the first bearing 314 protrudes from the side of the first slider 313 away from the longitudinal moving plate 31. The top and bottom inner walls of the first slot each have two first mounting holes, and both ends of the first rotating shaft are rotatably mounted within the two first mounting holes. The second slider 323 has several second slots on the side away from the transverse moving plate 32, each second slot corresponding to a second bearing 324. The second bearing 324 is housed in the corresponding second slot and fitted onto the outer circumference of the second rotating shaft. A portion of the second bearing 324 protrudes from the side of the second slider 323 away from the transverse moving plate 32. The top and bottom inner walls of the second slot each have two second mounting holes, and both ends of the second rotating shaft are rotatably mounted within the two second mounting holes.

[0058] Furthermore, two handles 36 are provided at each end of the transverse moving plate 32. When actually sampling the coated substrate, the operator holds the two handles 36 with both hands and moves the two handles 36 simultaneously in the transverse direction, thereby moving the transverse moving plate 32 in the transverse direction. By simultaneously moving the two handles 36 in the longitudinal direction, the transverse moving plate 32 can be moved in the longitudinal direction. The two handles 36 facilitate the movement of the transverse moving plate 32 and make operation convenient.

[0059] In this embodiment, two L-shaped blocks 361 are respectively provided at both ends of the transverse moving plate 32 on the side closest to the transverse moving plate 32, and two handles 36 are respectively provided on the two L-shaped blocks 361. The L-shaped blocks 361 can provide mounting support for the corresponding handles 36.

[0060] Furthermore, a control button 40 is provided at the top of the handle 36. The sampling device also includes a solenoid valve 60 and a PLC control module 50 disposed in the cutting base 21. The control button 40 and the solenoid valve 60 are both electrically connected to the PLC control module 50, and the drive unit 22 is connected to the solenoid valve 60. By pressing down on both control buttons 40 simultaneously, an open signal is output to the PLC control module 50 through the two control buttons 40. The PLC control module 50 can control the solenoid valve 60 to be energized according to the open signal. By pressing down on both control buttons 40 simultaneously again, a close signal is output to the PLC control module 50 through the two control buttons 40. The PLC control module 50 can control the solenoid valve 60 to be de-energized according to the close signal. The extension or retraction of the output end of the drive unit 22 can be controlled by the energization or de-energization of the solenoid valve 60. When sampling the coated substrate, at each sampling position along the length of the substrate below the cutter 23, the operator simultaneously presses two control buttons 40 downwards. This energizes the solenoid valve 60 via the PLC control module 50, which in turn extends the output end of the drive component 22. The extension of the output end of the drive component 22 drives the cutter 23 downwards. After the substrate is cut by the cutter 23, the operator simultaneously presses two control buttons 40 downwards. This de-energizes the solenoid valve 60 via the PLC control module 50, which then retracts the output end of the drive component 22. The retraction of the output end of the drive component 22 drives the cutter 23 upwards to its initial position.

[0061] The cutting base 21 is equipped with a power socket 70 at the position corresponding to the PLC control module 50. The power socket 70 is electrically connected to the PLC control module 50 and is used to connect to an external power source through a power cord, so that the PLC control module 50 can be powered by an external power source.

[0062] Furthermore, the sampling device also includes a counter 80 disposed within the drive component protective cover 212. Specifically, the counter 80 is disposed on the inner wall of one end of the drive component protective cover 212, and its panel extends from the through hole of the first sealing plate 213. The counter 80 is electrically connected to the PLC control module 50, which supplies power to the counter 80. The counter 80 is used to record the number of times the cutter 23 is used. Specifically, each time an start signal is output to the PLC control module 50 via the two control buttons 40, the PLC control module 50 sends a signal to the counter 80. The counter 80 counts this signal to obtain the number of times the cutter 23 is used. The recorded number of times the cutter 23 is used can be displayed on the panel of the counter 80. Recording the number of times the cutter 23 is used facilitates the detection of the cutter 23's lifespan.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
