[0088] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0089] like Figures 1 to 13As shown, the dust removal device 10 provided in this embodiment of the present invention includes a first conveying mechanism 1, a second conveying mechanism 2, and a dust removal mechanism 3. The dust removal mechanism 3 is disposed between the first conveying mechanism 1 and the second conveying mechanism 2 along a first direction x. The first conveying mechanism 1 includes a first width adjustment drive assembly 11, a first width adjustment frame 12, a second width adjustment frame 13, a first conveying assembly 14, and a second conveying assembly 15. The first width adjustment frame 12 and the second width adjustment frame 13 are disposed opposite each other along a second direction y, which is perpendicular to the first direction x. The first width adjustment drive assembly 11 is connected to the first width adjustment frame 12 and the second width adjustment frame 13, and is used to drive the first width adjustment frame 12 and the second width adjustment frame 13 to move closer to or further away from each other.

[0090] The first conveying assembly 14 is mounted on the first width-adjusting frame 12, and the second conveying assembly 15 is mounted on the second width-adjusting frame 13. The first conveying assembly 14 is used to cooperate with the second conveying assembly 15 to convey the material 20 to the dust removal mechanism 3 along the first direction x.

[0091] The dust removal mechanism 3 is used to remove dust from both sides of the material 20. The second conveying mechanism 2 is used to receive the dust-removed material 20 along the first direction x.

[0092] The dust removal device 10 provided in this embodiment of the utility model allows for automatic adjustment of the material 20 conveying width when the size of the material 20 changes. The first conveying mechanism 1 can drive the first width-adjusting frame 12 and the second width-adjusting frame 13 to move closer or further apart via the first width-adjusting drive component 11. This, in turn, causes the first conveying component 14 and the second conveying component 15 to move closer or further apart, thereby adjusting the distance between them and achieving automatic adjustment of the material 20 conveying width. After the material 20 conveying width is adjusted by the first conveying mechanism 1, the first conveying mechanism 1, through the cooperation of the first conveying component 14 and the second conveying component 15, conveys the material 20 to the dust removal mechanism 3. The dust removal mechanism 3 removes dust from both sides of the material 20, and then the second conveying mechanism 2 receives the dust-removed material 20 for subsequent testing. This dust removal device 10 can achieve automatic adjustment of the material 20 conveying width, is simpler and faster to operate, and is compatible with materials 20 of various sizes.

[0093] In one embodiment, the first conveying component 14 may be installed on the side of the first width adjusting frame 12 facing the second width adjusting frame 13, and the second conveying component 15 may be installed on the side of the second width adjusting frame 13 facing the first width adjusting frame 12. Thus, the material 20 can be limited in the second direction y by the first width adjusting frame 12 and the second width adjusting frame 13.

[0094] In one embodiment, such as Figures 2 to 5As shown, the first width adjustment drive assembly 11 includes a first width adjustment base 111, a first width adjustment drive component 112, a first width adjustment synchronous pulley 113, a second width adjustment synchronous pulley 114, and a first width adjustment synchronous belt 115. The first width adjustment synchronous pulley 113 and the second width adjustment synchronous pulley 114 are spaced apart along the second direction y, and the first width adjustment synchronous pulley 113 and the second width adjustment synchronous pulley 114 are respectively rotatably connected to the first width adjustment base 111. The first width adjustment synchronous belt 115 is wound around the first width adjustment synchronous pulley 113 and the second width adjustment synchronous pulley 114.

[0095] The first width adjustment drive 112 is mounted on the first width adjustment base 111. The output end of the first width adjustment drive 112 is connected to the first width adjustment synchronous wheel 113. The first width adjustment drive 112 is used to drive the first width adjustment synchronous wheel 113 to rotate.

[0096] A straight line passing through the center of the first width-adjusting synchronous pulley 113 and the center of the second width-adjusting synchronous pulley 114 is defined as the first width-adjusting virtual line. The first width-adjusting synchronous belt 115 includes a first part 1151 located on one side of the first width-adjusting virtual line along the first direction x and a second part 1152 located on the other side of the first width-adjusting virtual line along the first direction x. The first width-adjusting frame 12 is connected to the first part 1151, and the second width-adjusting frame 13 is connected to the second part 1152.

[0097] When the first width-adjusting drive unit 112 drives the first width-adjusting synchronous pulley 113 to rotate, the first width-adjusting synchronous belt 115 moves and drives the second width-adjusting synchronous pulley 114 to rotate in the same direction relative to the first width-adjusting synchronous pulley 113. At this time, the movement of the first width-adjusting synchronous belt 115 can simultaneously drive the first width-adjusting frame 12 and the second width-adjusting frame 13 to move in opposite directions along the second direction y, so as to move closer or further away from each other, thereby realizing automatic adjustment of the conveying width to accommodate materials 20 of various sizes.

[0098] In one embodiment, the first width adjustment drive 112 includes a first width adjustment motor, the output shaft of which is connected to a first width adjustment synchronous pulley 113 to drive the first width adjustment synchronous pulley 113 to rotate.

[0099] The first width-adjusting motor can be a servo motor. Servo motors can be parametrically adjusted, which can reduce debugging time, make calibration convenient and quick, and achieve higher accuracy.

[0100] In other embodiments not shown in the figures, a first width-adjusting reduction structure, such as a reduction gear set, can be provided between the output shaft of the first width-adjusting motor and the first width-adjusting synchronous pulley to prevent the speed of the first width-adjusting synchronous pulley from being too high. Furthermore, the first width-adjusting drive may also include a first width-adjusting cylinder, which is a rotary cylinder.

[0101] In one embodiment, such as Figures 2 to 3As shown, the first width adjustment frame 12 includes a first width adjustment connecting block 121 and a first width adjustment plate 122. The first width adjustment connecting block 121 is connected to the first part 1151, and the first width adjustment connecting block 121 is slidably connected to the first width adjustment base 111 along the second direction y.

[0102] The first width adjustment plate 122 is installed on the first width adjustment connecting block 121, and the first conveying assembly 14 is installed on the side of the first width adjustment plate 122 facing the second width adjustment frame 13.

[0103] The first width adjustment plate 122 is installed on the first width adjustment connecting block 121 to form the first width adjustment frame 12. By connecting the first width adjustment connecting block 121 to the first part 1151, the connection between the first width adjustment frame 12 and the first part 1151 is realized. At the same time, since the first width adjustment connecting block 121 is slidably connected to the first width adjustment base 111 along the second direction y, the movement of the first width adjustment frame 12 along the second direction y can be made more stable.

[0104] In one embodiment, such as Figures 4 to 5 As shown, the second width adjustment frame 13 includes a second width adjustment connecting block 131 and a second width adjustment plate 132. The second width adjustment connecting block 131 is connected to the second part 1152, and the second width adjustment connecting block 131 is slidably connected to the first width adjustment base 111 along the second direction y.

[0105] The second width adjustment plate 132 is installed on the second width adjustment connecting block 131, and the second conveying assembly 15 is installed on the side of the second width adjustment plate 132 facing the first width adjustment frame 12.

[0106] The second width adjustment plate 132 is installed on the second width adjustment connecting block 131 to form the second width adjustment frame 13. By connecting the second width adjustment connecting block 131 to the second part 1152, the connection between the second width adjustment frame 13 and the second part 1152 is realized. At the same time, since the second width adjustment connecting block 131 is slidably connected to the first width adjustment base 111 along the second direction y, the movement of the second width adjustment frame 13 along the second direction y can be made more stable.

[0107] In one embodiment, such as Figures 2 to 5 As shown, a first width-adjusting slide rail structure 1111 extending along the second direction y can be provided on the first width-adjusting base 111. The first width-adjusting connecting block 121 and the second width-adjusting connecting block 131 are slidably connected to the first width-adjusting slide rail structure 1111, so as to realize the sliding connection between the first width-adjusting connecting block 121 and the second width-adjusting connecting block 131 and the first width-adjusting base 111 respectively.

[0108] In one embodiment, such as Figures 1 to 5As shown, the first conveying assembly 14 includes a first conveying drive wheel 141, a first conveying synchronous wheel 142, a second conveying synchronous wheel 143, and a first conveying synchronous belt 144. The first conveying drive wheel 141, the first conveying synchronous wheel 142, and the second conveying synchronous wheel 143 are rotatably connected to the side of the first width adjusting frame 12 facing the second width adjusting frame 13, and the first conveying synchronous wheel 142 and the second conveying synchronous wheel 143 are spaced apart along a first direction x. The first conveying synchronous belt 144 is wound around the first conveying drive wheel 141, the first conveying synchronous wheel 142, and the second conveying synchronous wheel 143.

[0109] The second conveying assembly 15 includes a second conveying drive wheel 151, a third conveying synchronous wheel 152, a fourth conveying synchronous wheel 153, and a second conveying synchronous belt 154. The second conveying drive wheel 151, the third conveying synchronous wheel 152, and the fourth conveying synchronous wheel 153 are rotatably connected to the side of the second width adjusting frame 13 facing the first width adjusting frame 12, and the third conveying synchronous wheel 152 and the fourth conveying synchronous wheel 153 are spaced apart along the first direction x. The second conveying synchronous belt 154 is wound around the second conveying drive wheel 151, the third conveying synchronous wheel 152, and the fourth conveying synchronous wheel 153.

[0110] The first conveying mechanism 1 also includes a first conveying drive assembly 16, which is connected to the first conveying drive wheel 141 and the second conveying drive wheel 151. The first conveying drive assembly 16 is used to drive the first conveying drive wheel 141 and the second conveying drive wheel 151 to rotate synchronously.

[0111] The first conveying drive assembly 16 drives the first conveying drive wheel 141 and the second conveying drive wheel 151 to rotate synchronously, so as to drive the first conveying synchronous belt 144 and the second conveying synchronous belt 154 to move synchronously and convey the material 20. This can avoid the material 20 from deflecting due to the inconsistent movement speed of the first conveying synchronous belt 144 and the second conveying synchronous belt 154.

[0112] In one embodiment, such as Figures 2 to 5 As shown, along the height direction, the first conveying drive wheel 141 is located below the connecting line between the center of the first conveying synchronous wheel 142 and the center of the second conveying synchronous wheel 143, so as to avoid the first conveying drive wheel 141 interfering with the conveying of the material 20.

[0113] Along the height direction, the second conveying drive wheel 151 is located below the connecting line between the center of the third conveying synchronous wheel 152 and the center of the fourth conveying synchronous wheel 153, so as to avoid the second conveying drive wheel 151 interfering with the conveying of material 20.

[0114] In one embodiment, such as Figures 2 to 5As shown, the first transmission drive assembly 16 includes a first transmission drive component 161 and a first transmission drive rod 162. The output end of the first transmission drive component 161 is connected to the first transmission drive rod 162, and the first transmission drive component 161 is used to drive the first transmission drive rod 162 to rotate.

[0115] The first transmission drive wheel 141 and the second transmission drive wheel 151 are respectively connected to the first transmission drive rod 162.

[0116] When the first transmission drive member 161 drives the first transmission drive rod 162 to rotate, the first transmission drive wheel 141 and the second transmission drive wheel 151 connected to the first transmission drive rod 162 can rotate synchronously, thereby driving the first transmission synchronous belt 144 and the second transmission synchronous belt 154 to move synchronously.

[0117] In one embodiment, the first transmission drive 161 includes a first transmission motor, the output shaft of which is connected to a first transmission drive rod 162 to drive the first transmission drive rod 162 to rotate.

[0118] The first transmission motor can be selected as a servo motor. The servo motor can be parameterized, which can reduce debugging time, make calibration convenient and quick, and achieve higher accuracy.

[0119] In other embodiments not shown in the figures, a first transmission reduction structure, such as a reduction gear set, may be provided between the output shaft of the first transmission motor and the first transmission drive rod to prevent the rotational speed of the first transmission drive rod from being too high. Furthermore, the first transmission drive component may also include a first transmission cylinder, which is a rotary cylinder.

[0120] In one embodiment, such as Figures 1 to 5 As shown, the first conveying mechanism 1 also includes a first auxiliary conveying component 17, which is disposed between the first conveying component 14 and the second conveying component 15 along the second direction y. The first auxiliary conveying component 17 can support the material 20 conveyed by the first conveying component 14 and the second conveying component 15.

[0121] By setting the first auxiliary conveying component 17 to support the material 20 conveyed by the first conveying component 14 and the second conveying component 15, the first conveying mechanism 1 can convey larger materials 20, avoid the collapse of the middle of the larger materials 20 during conveying, and improve the transportation stability of the materials 20.

[0122] In one embodiment, such as Figures 1 to 5As shown, the first auxiliary conveying component 17 includes a first auxiliary support frame 171 and a plurality of first auxiliary wheels 172. The first auxiliary support frame 171 is disposed between the first conveying component 14 and the second conveying component 15 along the second direction y. The plurality of first auxiliary wheels 172 are rotatably connected to the first auxiliary support frame 171. The first auxiliary wheels 172 can provide rolling support for the material 20 conveyed by the first conveying component 14 and the second conveying component 15.

[0123] By setting the first auxiliary wheel 172, the material 20 is rolled and supported, thus preventing the first auxiliary conveying component 17 from scraping the surface of the material 20.

[0124] In one embodiment, such as Figures 1 to 5 As shown, some of the first auxiliary wheels 172 are disposed on the side of the first auxiliary support frame 171 facing the first conveying component 14, and the remaining first auxiliary wheels 172 are disposed on the side of the first auxiliary support frame 171 facing the second conveying component 15, so as to provide rolling support for the material 20 from multiple positions and improve the transportation stability of the material 20.

[0125] In one embodiment, such as Figure 1 , Figures 7 to 12 As shown, the dust removal mechanism 3 includes a dust removal bracket 31, a first dust removal roller assembly 32, and a second dust removal roller assembly 33. The first dust removal roller assembly 32 and the second dust removal roller assembly 33 are arranged opposite each other on the dust removal bracket 31 along a third direction z. The third direction z, the second direction y, and the first direction x are all perpendicular to each other. The third direction z can be a height direction, in which case the first dust removal roller assembly 32 is located above the second dust removal roller assembly 33.

[0126] A dust removal gap is formed between the first dust removal roller group 32 and the second dust removal roller group 33 for the material 20 to pass through. The first dust removal roller group 32 is used to remove dust from the first side surface of the material 20, and the second dust removal roller group 33 is used to remove dust from the second side surface of the material 20.

[0127] By setting up a first dust removal roller group 32 and a second dust removal roller group 33 that are opposite each other along the third direction z, dust removal can be achieved on both sides of the material 20.

[0128] In one embodiment, such as Figures 7 to 12As shown, the first dust removal roller assembly 32 includes a first rubber-coated roller 321 and a first paper-adhesive roller 322. The first rubber-coated roller 321 and the first paper-adhesive roller 322 are rotatably connected to the dust removal bracket 31, and the first paper-adhesive roller 322 is located on the side of the first rubber-coated roller 321 away from the second dust removal roller assembly 33. The first rubber-coated roller 321 is used to remove dust from the first side surface of the material 20. The first paper-adhesive roller 322 rolls in contact with the first rubber-coated roller 321 and is used to remove dust from the surface of the first rubber-coated roller 321.

[0129] The second dust removal roller assembly 33 includes a second rubber-coated roller 331 and a second paper-adhesive roller 332. The second rubber-coated roller 331 and the second paper-adhesive roller 332 are rotatably connected to the dust removal bracket 31, and the second paper-adhesive roller 332 is located on the side of the second rubber-coated roller 331 away from the first dust removal roller assembly 32. The second rubber-coated roller 331 is used to remove dust from the second side surface of the material 20. The second paper-adhesive roller 332 rolls in contact with the second rubber-coated roller 331 and is used to remove dust from the surface of the second rubber-coated roller 331.

[0130] The dust removal gap is formed between the first rubber-coated roller 321 and the second rubber-coated roller 331.

[0131] By forming a dust removal gap between the first coated roller 321 and the second coated roller 331, the material 20 can pass between them. The first coated roller 321 and the second coated roller 331 can respectively remove dust from the first and second side surfaces of the material 20, preventing impurities on the surface of the material 20 from interfering with subsequent test results. Simultaneously, the first adhesive roller 322 and the second adhesive roller 332 respectively remove dust from the surfaces of the first coated roller 321 and the second coated roller 331, ensuring that the first coated roller 321 and the second coated roller 331 remain clean at all times, thereby continuously removing impurities from both sides of the material 20.

[0132] In one embodiment, the surface of the first coated roller 321 is coated with a first adhesive material (such as silicone), and the first adhesive roller 322 is provided with multiple layers of first adhesive paper (such as PE adhesive paper, i.e., polyethylene adhesive paper). The adhesiveness of the first adhesive paper is greater than that of the first adhesive material, so that the first adhesive roller 322 can remove dust from the first coated roller 321. When the outermost layer of the first adhesive paper on the first adhesive roller 322 has a lot of dust, the outermost layer of the first adhesive paper can be peeled off to expose the inner layer of the first adhesive paper to continue removing dust from the first coated roller 321. After all the first adhesive paper on the first adhesive roller 322 has been dusted, the first adhesive roller 322 can be removed and replaced.

[0133] The surface of the second adhesive roller 331 is coated with a second adhesive material (such as silicone). The second adhesive roller 332 has multiple layers of second adhesive paper (such as PE adhesive paper, i.e., polyethylene adhesive paper). The adhesiveness of the second adhesive paper is greater than that of the second adhesive material, so that the second adhesive roller 332 can remove dust from the second adhesive roller 331. When the outermost layer of the second adhesive paper on the second adhesive roller 332 has a lot of dust, the outermost layer of the second adhesive paper can be peeled off to expose the inner layer of the second adhesive paper to continue removing dust from the second adhesive roller 331. After all the second adhesive paper on the second adhesive roller 332 has been dust-free, the second adhesive roller 332 can be removed and replaced.

[0134] In one embodiment, such as Figures 7 to 12 As shown, the first dust removal roller assembly 32 also includes a first dust removal support frame 323, which is movably mounted on the dust removal bracket 31 along the third direction z, and the first adhesive roller 322 is rotatably connected to the first dust removal support frame 323.

[0135] The second dust removal roller assembly 33 also includes a second dust removal support frame 333, which is movably mounted on the dust removal bracket 31 along the third direction z, and the second adhesive roller 332 is rotatably connected to the second dust removal support frame 333.

[0136] By rotatably connecting the first adhesive roller 322 to the first dust removal support frame 323, and by movably mounting the first dust removal support frame 323 to the dust removal bracket 31 along the third direction z, the first adhesive roller 322 can be replaced by insertion. Similarly, by rotatably connecting the second adhesive roller 332 to the second dust removal support frame 333, and by movably mounting the second dust removal support frame 333 to the dust removal bracket 31 along the third direction z, the second adhesive roller 332 can be replaced by insertion.

[0137] In one embodiment, such as Figures 7 to 12 As shown, the first dust removal support frame 323 includes a first dust removal support plate 3231, a second dust removal support plate 3232, a first dust removal connector 3233, a first dust removal handle 3234, and a first dust removal elastic member 3235. The first dust removal support plate 3231 and the second dust removal support plate 3232 are spaced apart along the second direction y, and the first dust removal connector 3233 is connected between the first dust removal support plate 3231 and the second dust removal support plate 3232.

[0138] The first dust removal support plate 3231 is provided with a first dust removal insertion hole. The first end of the first adhesive roller 322 is rotatably inserted into the first dust removal insertion hole, and the second end of the first adhesive roller 322 is provided with a first dust removal locking hole. The second dust removal support plate 3232 is provided with a second dust removal insertion hole.

[0139] The first dust removal handle 3234 can be inserted into the first dust removal lock hole through the second dust removal insertion hole. The first dust removal elastic member 3235 is elastically connected between the first dust removal handle 3234 and the first dust removal support frame 323, and the first dust removal elastic member 3235 is located on the side of the second dust removal support plate 3232 facing the first dust removal support plate 3231.

[0140] In the initial state, the first dust removal handle 3234 is inserted into the first dust removal locking hole to lock the first adhesive roller 322 to the first dust removal support frame 323. When the first adhesive roller 322 needs to be replaced, the first dust removal handle 3234 can be pulled away from the first dust removal support plate 3231. This compresses the first dust removal elastic element 3235 and moves the first dust removal handle 3234 away from the first dust removal locking hole, allowing the first adhesive roller 322 to be removed and enabling quick replacement of the first adhesive roller 322.

[0141] In one embodiment, such as Figures 7 to 12 As shown, the second dust removal support frame 333 includes a third dust removal support plate 3331, a fourth dust removal support plate 3332, a second dust removal connector 3333, a second dust removal handle 3334, and a second dust removal elastic member 3335. The third dust removal support plate 3331 and the fourth dust removal support plate 3332 are spaced apart along the second direction y, and the second dust removal connector 3333 is connected between the third dust removal support plate 3331 and the fourth dust removal support plate 3332.

[0142] The third dust removal support plate 3331 is provided with a third dust removal insertion hole. The first end of the second adhesive roller 332 is rotatably inserted into the third dust removal insertion hole, and the second end of the second adhesive roller 332 is provided with a second dust removal locking hole. The fourth dust removal support plate 3332 is provided with a fourth dust removal insertion hole.

[0143] The second dust removal handle 3334 can be inserted into the second dust removal lock hole through the fourth dust removal insertion hole. The second dust removal elastic member 3335 is elastically connected between the second dust removal handle 3334 and the fourth dust removal support plate 3332, and the second dust removal elastic member 3335 is located on the side of the fourth dust removal support plate 3332 facing the third dust removal support plate 3331.

[0144] In the initial state, the second dust removal handle 3334 is inserted into the second dust removal locking hole to lock the second adhesive roller 332 to the second dust removal support frame 333. When the second adhesive roller 332 needs to be replaced, the second dust removal handle 3334 can be pulled away from the third dust removal support plate 3331. This compresses the second dust removal elastic element 3335 and moves the second dust removal handle 3334 away from the second dust removal locking hole, allowing the second adhesive roller 332 to be removed and enabling quick replacement of the second adhesive roller 332.

[0145] In one embodiment, such as Figures 7 to 12 As shown, the dust removal bracket 31 has a dust removal notch 311 on one side along the second direction y.

[0146] The dust removal mechanism 3 also includes a dust removal support frame drive assembly 34, which is mounted on the dust removal bracket 31. The output end of the dust removal support frame drive assembly 34 is connected to the second dust removal support frame 333. The dust removal support frame drive assembly 34 is used to drive the second dust removal support frame 333 to move relative to the dust removal bracket 31 along the third direction z.

[0147] The second dust removal support frame 333 has a first position and a second position.

[0148] In the first position, the second adhesive roller 332 can remove dust from the surface of the second adhesive roller 331. In the second position, the second dust removal support 333 can be removed from the dust removal notch 311 along the second direction y, so as to realize the removal and replacement of the second dust removal support 333.

[0149] The reason why the second dust removal support frame 333 is taken out from the dust removal notch 311 along the second direction y is that the dust removal mechanism 3 is provided with a first conveying mechanism 1 and a second conveying mechanism 2 on both sides along the first direction x. This means that when the second dust removal support frame 333 is taken out in the first direction x, it will be blocked by the first conveying mechanism 1 and the second conveying mechanism 2. In addition, when the dust removal mechanism 3 is used in PCB board testing equipment, the dust removal mechanism 3 will be installed on the machine base of the PCB board testing equipment, making it difficult to have space at the bottom of the dust removal mechanism 3 along the third direction z to take out the second dust removal support frame 333. Therefore, the second dust removal support frame 333 is set to be taken out from the dust removal notch 311 along the second direction y.

[0150] In one embodiment, such as Figures 7 to 12 As shown, the dust removal support frame drive assembly 34 includes a dust removal support frame drive component 341 and a dust removal support frame drive rod 342. The dust removal support frame drive component 341 is mounted on the dust removal bracket 31, and the output end of the dust removal support frame drive component 341 is connected to the dust removal support frame drive rod 342. The dust removal support frame drive component 341 is used to drive the dust removal support frame drive rod 342 to move along the third direction z, thereby driving the second dust removal support frame 333 to move along the third direction z. The dust removal support frame drive component 341 can be a cylinder.

[0151] The third direction, z, is the height direction. When the dust removal support frame drive member 341 drives the dust removal support frame drive rod 342 upward, the second dust removal support frame 333 can move upward with the dust removal support frame drive rod 342, so that the second adhesive roller 332 contacts the second rubber-coated roller 331 to remove dust from the surface of the second rubber-coated roller 331. When the dust removal support frame drive member 341 drives the dust removal support frame drive rod 342 downward, the second dust removal support frame 333 can move downward under the action of gravity, so that the second adhesive roller 332 gradually moves away from the second rubber-coated roller 331 until the second adhesive roller 332 moves to the dust removal notch 311 so that it can be removed and replaced.

[0152] In one embodiment, such as Figures 7 to 12 As shown, the dust removal mechanism 3 also includes a dust removal slide rail assembly 35, which is movably connected to the dust removal bracket 31 along the second direction y.

[0153] In the second position, the second dust removal support frame 333 can move along the second direction y with the dust removal slide rail assembly 35, so as to realize the removal and replacement of the second dust removal support frame 333.

[0154] In one embodiment, the dust removal slide rail assembly 35 can be selected as an industrial slide rail. One end of the industrial slide rail along the second direction y is provided with a slide rail handle. By pulling the slide rail handle, the industrial slide rail can be driven to move along the second direction y.

[0155] In one embodiment, such as Figures 7 to 12 As shown, the dust removal mechanism 3 also includes a dust removal drive assembly 36, which is mounted on the dust removal bracket 31. The output end of the dust removal drive assembly 36 is connected to the first rubber-coated roller 321, and the dust removal drive assembly 36 is used to drive the first rubber-coated roller 321 to rotate.

[0156] The dust removal drive assembly 36 drives the first rubber-coated roller 321 to rotate, thereby driving all rollers to rotate and achieving dust removal of the material 20.

[0157] In one embodiment, the dust removal drive assembly 36 can be selected as a motor in conjunction with a synchronous pulley and a synchronous belt to drive the rotation of the first rubber-coated roller 321.

[0158] In one embodiment, such as Figure 7 and Figure 9 As shown, the dust removal mechanism 3 also includes a first transition roller 37 and a second transition roller 38. The first transition roller 37 and the second transition roller 38 are respectively installed on the dust removal bracket 31, and the first transition roller 37 and the second transition roller 38 are located on opposite sides of the second rubber-coated roller 331 along the first direction x.

[0159] The first transition roller 37 can carry the material 20 between the first conveying mechanism 1 and the second rubber-coated roller 331, and the second transition roller 38 can carry the material 20 between the second conveying mechanism 2 and the second rubber-coated roller 331. By setting the first transition roller 37 and the second transition roller 38, the material 20 is provided with transition support for conveying at the dust removal mechanism 3, reducing the possibility of the material 20 bending at the dust removal mechanism 3.

[0160] In one embodiment, along a projection plane perpendicular to the first direction x, the orthographic projection of the second rubber-coated roller 331 near the edge of the first rubber-coated roller 321, the orthographic projection of the first transition roller 37 near the edge of the first rubber-coated roller 321, and the orthographic projection of the second transition roller 38 near the edge of the first rubber-coated roller 321 overlap, so that the second rubber-coated roller 331, the first transition roller 37, and the second transition roller 38 form a relatively flat support plane to support the material 20.

[0161] In one embodiment, such as Figure 1 , Figure 13 As shown, the structure of the second conveying mechanism 2 is identical to that of the first conveying mechanism 1. Specifically, the second conveying mechanism 2 includes a second width-adjusting drive assembly 21, a third width-adjusting frame 22, a fourth width-adjusting frame 23, a third conveying assembly 24, and a fourth conveying assembly. The third width-adjusting frame 22 and the fourth width-adjusting frame 23 are arranged opposite to each other along the second direction y. The second width-adjusting drive assembly 21 is connected to the third width-adjusting frame 22 and the fourth width-adjusting frame 23, and is used to drive the third width-adjusting frame 22 and the fourth width-adjusting frame 23 to move closer to or further away from each other.

[0162] The third conveying assembly 24 is installed on the side of the third width adjusting frame 22 facing the fourth width adjusting frame 23, and the fourth conveying assembly is installed on the side of the fourth width adjusting frame 23 facing the third width adjusting frame 22. The third conveying assembly 24 is used to cooperate with the fourth conveying assembly to receive the dust-removed material 20 along the first direction x.

[0163] When the size of material 20 changes, the second conveying mechanism 2 can drive the third and fourth width-adjusting frames 22 and 23 to move closer or further apart via the second width-adjusting drive assembly 21. This, in turn, causes the third and fourth conveying components 24 to move closer or further apart, thereby adjusting the distance between them and achieving automatic adjustment of the material 20 conveying width. After the material 20 conveying width adjustment by the second conveying mechanism 2 is completed, the dust-removed material 20 can be received for subsequent testing.

[0164] In one embodiment, such as Figure 13As shown, the second width adjustment drive assembly 21 includes a second width adjustment base 211, a second width adjustment drive component 212, a third width adjustment synchronous pulley, a fourth width adjustment synchronous pulley 213, and a second width adjustment synchronous belt 214. The third and fourth width adjustment synchronous pulleys 213 are spaced apart along the second direction y, and are rotatably connected to the second width adjustment base 211. The second width adjustment synchronous belt 214 is wound around the third and fourth width adjustment synchronous pulleys 213.

[0165] The second width adjustment drive 212 is mounted on the second width adjustment base 211. The output end of the second width adjustment drive 212 is connected to the third width adjustment synchronous wheel. The second width adjustment drive 212 is used to drive the third width adjustment synchronous wheel to rotate.

[0166] The straight line passing through the center of the third width-adjusting synchronous pulley and the center of the fourth width-adjusting synchronous pulley 213 is defined as the second width-adjusting virtual line. The second width-adjusting synchronous belt 214 includes a third part located on one side of the second width-adjusting virtual line along the first direction x and a fourth part located on the other side of the second width-adjusting virtual line along the first direction x. The third width-adjusting frame 22 is connected to the third part, and the fourth width-adjusting frame 23 is connected to the fourth part.

[0167] When the second width-adjusting drive 212 drives the third width-adjusting synchronous pulley to rotate, the second width-adjusting synchronous belt 214 moves and drives the fourth width-adjusting synchronous pulley 213 to rotate in the same direction relative to the third width-adjusting synchronous pulley.

By connecting the third width adjustment connecting block 221 to the third part, the connection between the third width adjustment frame 22 and the third part is realized. At the same time, since the third width adjustment connecting block 221 is slidably connected to the second width adjustment base 211 along the second direction y, the movement of the third width adjustment frame 22 along the second direction y can be made more stable.

[0174] In one embodiment, such as Figure 13 As shown, the fourth width adjustment frame 23 includes a fourth width adjustment connecting block 231 and a fourth width adjustment plate 232.

[0175] The fourth width adjustment plate 232 is installed on the fourth width adjustment connecting block 231, and the fourth conveying assembly is installed on the side of the fourth width adjustment plate 232 facing the third width adjustment frame 22.

[0176] The fourth width adjustment plate 232 is installed on the fourth width adjustment connecting block 231 to form the fourth width adjustment frame 23. By connecting the fourth width adjustment connecting block 231 to the fourth part, the connection between the fourth width adjustment frame 23 and the fourth part is realized. At the same time, since the fourth width adjustment connecting block 231 is slidably connected to the second width adjustment base 211 along the second direction y, the movement of the fourth width adjustment frame 23 along the second direction y can be made more stable.

[0177] In one embodiment, such as Figure 13 As shown, a second width-adjusting slide rail structure 2111 extending along the second direction y can be provided on the second width-adjusting base 211. The third width-adjusting connecting block 221 and the fourth width-adjusting connecting block 231 are slidably connected to the second width-adjusting slide rail structure 2111, so as to realize the slidable connection between the third width-adjusting connecting block 221 and the fourth width-adjusting connecting block 231 and the second width-adjusting base 211 respectively.

[0180] The second conveying mechanism 2 also includes a second conveying drive assembly 25, which is connected to the third conveying drive wheel 241 and the fourth conveying drive wheel. The second conveying drive assembly 25 is used to drive the third conveying drive wheel 241 and the fourth conveying drive wheel to rotate synchronously.

[0181] The second transmission drive assembly 25 drives the third transmission drive wheel 241 and the fourth transmission drive wheel to rotate synchronously, so as to drive the third transmission synchronous belt 244 and the fourth transmission synchronous belt to move synchronously and convey the material 20. This can avoid the material 20 from deflecting due to the inconsistent movement speed of the third transmission synchronous belt 244 and the fourth transmission synchronous belt.

[0182] In one embodiment, such as Figure 13 As shown, along the height direction, the third conveying drive wheel 241 is located below the connecting line between the center of the fifth conveying synchronous wheel 242 and the center of the sixth conveying synchronous wheel 243, so as to avoid the third conveying drive wheel 241 interfering with the conveying of material 20.

[0183] Along the height direction, the fourth conveyor drive wheel is located below the line connecting the center of the seventh conveyor synchronous wheel and the center of the eighth conveyor synchronous wheel, so as to avoid the fourth conveyor drive wheel interfering with the conveying of material 20.

[0185] The third and fourth transmission drive wheels are respectively connected to the second transmission drive rod 252.

[0186] When the second transmission drive member 251 drives the second transmission drive rod 252 to rotate, the third transmission drive wheel 241 and the fourth transmission drive wheel connected to the second transmission drive rod 252 can rotate synchronously, thereby driving the third transmission synchronous belt 244 and the fourth transmission synchronous belt to move synchronously.

[0187] In one embodiment, the second transmission drive 251 includes a second transmission motor, the output shaft of which is connected to the second transmission drive rod 252 to drive the second transmission drive rod 252 to rotate.

[0188] The second transmission motor can be selected as a servo motor. The servo motor can be parameterized, which can reduce debugging time, make calibration convenient and quick, and achieve higher accuracy.

Furthermore, the second transmission drive component may also include a second transmission cylinder, which is a rotary cylinder.

[0190] In one embodiment, such as Figure 1 and Figure 13 As shown, the second conveying mechanism 2 also includes a second auxiliary conveying component 26, which is disposed between the third conveying component 24 and the fourth conveying component along the second direction y. The second auxiliary conveying component 26 can support the material 20 conveyed by the third conveying component 24 and the fourth conveying component.

[0191] By setting a second auxiliary conveying component 26 to support the material 20 conveyed by the third conveying component 24 and the fourth conveying component, the second conveying mechanism 2 can convey larger materials 20, avoid the collapse of the middle of the larger materials 20 during conveying, and improve the transportation stability of the materials 20.

[0192] In one embodiment, such as Figure 13 As shown, the second auxiliary conveying component 26 includes a second auxiliary support frame 261 and a plurality of second auxiliary wheels 262. The second auxiliary support frame 261 is disposed between the third conveying component 24 and the fourth conveying component along the second direction y.

The second auxiliary wheels 262 can provide rolling support for the material 20 conveyed by the third conveying component 24 and the fourth conveying component.

[0193] By setting a second auxiliary wheel 262, the material 20 is rolled and supported, thus preventing the second auxiliary conveying component 26 from scraping the surface of the material 20.

[0194] In one embodiment, such as Figure 13 As shown, some of the second auxiliary wheels 262 are disposed on the side of the second auxiliary support frame 261 facing the third conveying component 24, and the remaining second auxiliary wheels 262 are disposed on the side of the second auxiliary support frame 261 facing the fourth conveying component, so as to provide rolling support for the material 20 from multiple positions and improve the transportation stability of the material 20.

[0196] The dust removal device 10 also includes a sensing mechanism 4, which is located at the material picking position and is used to sense whether the material 20 on the second conveying mechanism 2 has reached the material picking position.

[0197] When the sensing mechanism 4 senses that the material 20 on the second conveying mechanism 2 has reached the picking position, the second conveying mechanism 2 stops continuously conveying the material 20. After the material 20 is picked up by the second conveying mechanism 2, the second conveying mechanism 2 continues to convey the next material 20.

[0198] In one embodiment, the sensing mechanism 4 may be selected as a photoelectric sensor.

[0200] Material 20 is a PCB board.

[0201] According to the PCB board testing equipment of this utility model embodiment, when the size of the material 20 changes, the first conveying mechanism 1 can drive the first width-adjusting frame 12 and the second width-adjusting frame 13 to move closer or further apart through the first width-adjusting drive component 11, thereby driving the first conveying component 14 and the second conveying component 15 to move closer or further apart, so as to adjust the distance between the first conveying component 14 and the second conveying component 15 and realize the automatic adjustment of the conveying width of the material 20. After the material 20 conveying width of the first conveying mechanism 1 is adjusted, the first conveying mechanism 1, through the cooperation of the first conveying component 14 and the second conveying component 15, conveys the material 20 to the dust removal mechanism 3, which removes dust from both sides of the material 20. Then, the second conveying mechanism 2 receives the dust-removed material 20 for subsequent testing. This dust removal device 10 can realize the automatic adjustment of the conveying width of the material 20, the operation is simpler and faster, and it is compatible with materials 20 of various sizes.
