[0093] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0094] like Figure 1 As shown, the detection device 1000 of the present application may include a carrier 100, an appearance detection component 200, and a fifth drive component 300. The carrier 100 is used to clamp a workpiece to be inspected for appearance. The appearance detection component 200 is used to collect data characterizing the appearance characteristics of the workpiece. The fifth drive component 300 is used to drive the carrier 100 to move so as to adjust the orientation of the carrier 100.

[0095] like Figure 2 As shown in FIG. 1 , the workpiece 10 to be inspected for appearance may be the upper cover, lower cover or middle frame of a laptop computer. For the convenience of description, the workpiece 10 is abstracted into a rectangular block with a certain thickness, including a front and a back side opposite to each other, and four side surfaces A, B, C, and D connected between the front and the back side. The appearance inspection area is as follows: Figure 2 The section line area shows four side faces and partial areas of the front and back faces on each side face.

[0096] During the inspection, the workpiece 10 is clamped on the carrier 100, and the four sides A, B, C, and D of the workpiece 10 are sequentially passed through the appearance inspection component 200 under the drive of the fifth driving component 300, thereby completing the appearance inspection. For example, when the side A passes through the appearance component 200, the appearance inspection component 200 collects the appearance data of the side A and the front and back parts of the side A adjacent to the side A (by taking pictures and scanning the contour, see the description of the appearance inspection component 200 below).

[0097] The carrier 100 , the appearance detection assembly 200 and the fifth driving assembly 300 are respectively described in detail below.

[0098] like Figure 3 and Figure 4 As shown, the carrier embodiment of the present application may include a base 110, a first positioning assembly 120, a first drive assembly 130, a second drive assembly 140, a second positioning assembly 150, a third positioning assembly 160, a third drive assembly 170, a fourth drive assembly 180 and a fourth positioning assembly 190.

[0099] The first positioning assembly 120 is fixed to the base 110. The first driving assembly 130 is disposed on the base 110. The second driving assembly 140 is disposed on the first driving assembly 130. The second positioning assembly 150 is disposed on the second driving assembly 140. The first driving assembly 130 is used to drive the second driving assembly 140 to move relative to the first positioning assembly 120, and the second driving assembly 140 is used to drive the second positioning assembly 150 to move relative to the first positioning assembly 120, so that the second positioning assembly 150 and the first positioning assembly 120 clamp the workpiece 10 from both sides (clamp the workpiece 10 from both sides of the side A and B).

[0100] The third positioning assembly 160 is fixed to the base 110. The third driving assembly 170 is disposed on the base 110. The fourth driving assembly 180 is disposed on the third driving assembly 170. The fourth positioning assembly 190 is disposed on the fourth driving assembly 180. The third driving assembly 170 is used to drive the fourth driving assembly 180 to move relative to the third positioning assembly 160, and the fourth driving assembly 180 is used to drive the fourth positioning assembly 190 to move relative to the third positioning assembly 160, so that the fourth positioning assembly 190 and the third positioning assembly 160 clamp the workpiece 10 from both sides (clamp the workpiece 10 from both sides of the side C and D). The moving direction of the fourth positioning assembly 190 relative to the third positioning assembly 160 is different from the moving direction of the second positioning assembly 150 relative to the first positioning assembly 120.

[0101] The second positioning assembly 150 moves in the first direction relative to the first positioning assembly 120. The fourth positioning assembly 190 moves in the second direction relative to the third positioning assembly 160. In this embodiment, the first direction is perpendicular to the second direction. In other embodiments, the first direction and the second direction may also be arranged obliquely.

[0102] The base 110 is generally rectangular and has four side surfaces a, b, c, and d. After the workpiece 10 is clamped on the carrier 100, the four side surfaces a, b, c, and d of the base 110 correspond to the four side surfaces A, B, C, and D of the workpiece 10. The second positioning assembly 150, the first positioning assembly 120, the fourth positioning assembly 190, and the third positioning assembly 160 are respectively disposed on one side of the four side surfaces a, b, c, and d of the base 110.

[0103] On the side b of the base 110, two first positioning components 120 are arranged at intervals. On the side a of the base 110, a second positioning component 150 is arranged. On the side d of the base 110, two third positioning components 160 are arranged at intervals. On the side c of the base 110, two fourth positioning components 190 are arranged at intervals. The specific number of the first positioning component 120, the second positioning component 150, the third positioning component 160, and the fourth positioning component 190 can be adjusted according to specific needs.

[0104] The working principle and working process of this embodiment will be specifically described below using a solution of clamping the workpiece 10 from both sides A and B. The solution of clamping the workpiece 10 from both sides C and D can be understood by reference.

[0105] Driven by the first drive assembly 130, the second positioning assembly 150 moves within a first predetermined range relative to the first positioning assembly 120. Driven by the second drive assembly 140, the second positioning assembly 150 moves within a second predetermined range relative to the first positioning assembly 120. In this embodiment, the second positioning assembly 150 moves within the first predetermined range to accommodate workpieces 10 of different specifications. The second positioning assembly 150 moves within the second predetermined range to clamp the workpiece 10. In other embodiments, the second positioning assembly 150 may also move within the second predetermined range to accommodate workpieces 10 of different specifications. The second positioning assembly 150 moves within the first predetermined range to clamp the workpiece 10.

[0106] Figure 5 The schematic diagram is a structural diagram of clamping the workpiece 10 on both sides A and B. The dotted boxes in the figure represent the limit positions of the second driving assembly 140 and the second positioning assembly 150 respectively.

[0107] like Figure 5 As shown, the above-mentioned first predetermined range A=L2-L1. L1 is the minimum distance of the second drive assembly 140 relative to the first positioning assembly 120. L2 is the maximum distance of the second drive assembly 140 relative to the first positioning assembly 120. The above-mentioned second predetermined range B=L4-L3. L3 is the minimum distance of the second positioning assembly 150 relative to the first positioning assembly 120 when the second drive assembly 140 is fixed (located at the first predetermined position). L4 is the maximum distance of the second positioning assembly 150 relative to the first positioning assembly 120 when the second drive assembly 140 is fixed. The first predetermined range A can be 50mm, so it can generally be compatible with different workpieces 10 with sizes fluctuating within the range of 50mm. The second predetermined range B can be 10mm. The above-mentioned A, B, L1, L2, L3, L4 and the following L0 are all dimensions in the first direction.

[0108] Refer to the following Figures 3 to 5 Introduce the installation and clamping process:

[0109] The first driving assembly 130 drives the second driving assembly 140 to move to a first predetermined position. When the second driving assembly 140 is located at the first predetermined position, a distance L0 between the side surfaces A and B of the workpiece 10 is greater than L3 and less than L4.

[0110] The second driving assembly 140 drives the second positioning assembly 150 away from the first positioning assembly 120 .

[0111] (Place the workpiece 10 on the vacuum chuck 101 , see below for the vacuum chuck 101 ) With the first positioning assembly 120 as a reference, place the side B of the workpiece 10 against the first positioning assembly 120 to define the position of the workpiece 10 on the base 110 .

[0112] The second driving assembly 140 drives the second positioning assembly 150 to approach the first positioning assembly 120 , so that the second positioning assembly 150 contacts the side surface A of the workpiece 10 , thereby clamping the workpiece 10 from both sides of the side surfaces A and B.

[0113] In this embodiment, the first driving assembly 130 enables the carrier 100 to be compatible with workpieces 10 of different specifications.

[0114] like Figure 3 and Figure 4 As shown, when the moving direction of the second driving component 140 relative to the first positioning component 120 forms an acute angle with the first direction, the second driving component 140 will also generate movement in the first direction (the spacing direction of the side surfaces A and B of the workpiece 10) when moving. Similarly, when the moving direction of the second positioning component 150 relative to the first positioning component 120 forms an acute angle with the first direction, the second driving component 140 will also generate movement in the first direction when moving. However, in order to improve the clamping efficiency, in this embodiment, the second driving component 140 and the second positioning component 150 move relative to the first positioning component 120 in the same direction (first direction). Similarly, the fourth driving component 180 and the fourth positioning component 190 move relative to the third positioning component 160 in the same direction (second direction).

[0115] The specific structure of the second driving assembly 140 is introduced below, and the fourth driving assembly 180 can be implemented by reference.

[0116] like Figure 4 , Figure 6 and Figure 7 As shown, the second driving assembly 140 includes a first movable member 141 , a first guide member 144 , a first driver 142 and an elastic member 143 .

[0117] The first guide member 144 is connected between the first movable member 141 and the first driving assembly 130, and is used to guide the first movable member 141 to move relative to the first driving assembly 130 in a first direction to approach or move away from the first positioning assembly 120. The first driver 142 is used to drive the first movable member 141 away from the first positioning assembly 120. The elastic member 143 is connected between the first movable member 141 and the first driving assembly 130, and is used to generate an elastic force to drive the first movable member 141 to approach the first positioning assembly 120. The second positioning assembly 150 is fixed to the first movable member 141.

[0118] In this embodiment, the first guide member 144 is a slide rail and slider structure. In other embodiments, a guide column, guide sleeve structure or other structures may be used to guide the first movable member 141 to move relative to the first driving assembly 130 .

[0119] In this embodiment, the first driver 142 is disposed on the side of the first movable member 141 facing the first positioning assembly 120, and the first driver 142 is a first cylinder 142, which includes a first cylinder body 1421 and a first piston rod 1422 that can move relatively, the first cylinder body 1421 is fixed to the first driving assembly 130, and the free end of the first piston rod 1422 is used to abut against the first movable member 141. In other embodiments, the first driver 142 may also be an oil cylinder or an electric cylinder.

[0120] In this embodiment, the elastic member 143 is a spring, which is always in a stretched state, and generates an elastic force toward the first positioning assembly 120. In other embodiments, other elastic elements, such as rubber pads, may also be used.

[0121] Before clamping the workpiece 10 , the first movable member 141 is located at a position closest to the first positioning assembly 120 under the elastic force of the elastic member 143 .

[0122] When clamping the workpiece 10 , the first driver 142 is controlled to generate a driving force to overcome the elastic force of the elastic member 143 , thereby driving the first movable member 141 away from the first positioning assembly 120 .

[0123] After the side B of the workpiece 10 is pressed against the first positioning assembly 120 to complete positioning, the first driver 142 is controlled to remove the driving force, so that the first movable member 141 presses against the side A of the workpiece 10 under the elastic force of the elastic member 143 , thereby clamping the workpiece 10 .

[0124] After the appearance inspection is completed, when the workpiece 10 is removed, the first driver 142 is controlled to generate a driving force to overcome the elastic force of the elastic member 143 to drive the first movable member 141 away from the first positioning assembly 120 .

[0125] The workpiece 10 is removed.

[0126] The first driver 142 is controlled to remove the driving force, and the first movable member 141 is located at a position closest to the first positioning assembly 120 under the elastic force of the elastic member 143 .

[0127] The second driving assembly 140 clamps the workpiece 10 by elastic force, and the clamping force is constant and adjustable, thereby avoiding damage to the workpiece 10 .

[0128] In order to block the workpiece 10 as little as possible, the size of the base 110 is designed to be relatively small, and the space for installing the first drive assembly 130 and the second drive assembly 140 is limited. In order to make the connection structure between the first drive assembly 130, the second drive assembly 140 and the base 110 more compact to save space, the first drive assembly 130 and the second drive assembly 140 can be respectively arranged on both sides of the base 110.

[0129] like Figure 6 As shown, the base 110 has a front side 111 and a back side 112 opposite to each other, and is provided with a through mounting hole 113. The mounting hole 113 connects the front side 111 and the back side 112 of the base 110. The second driving assembly 140 is disposed on the front side 111 of the base 110. A portion of the second movable member 131 is located on the back side 112 of the base 110, and the other portion passes through the mounting hole 113 and is connected to the second driving assembly 140.

[0130] like Figure 3 , Figure 4 , Figures 6 to 8 As shown, specifically, the first driving assembly 130 includes a second movable member 131 , a second guide member 133 and a second driver 132 .

[0131] A portion of the second movable member 131 is located on one side of the back side 112 of the base 110, and another portion thereof passes through the mounting hole 113 and is connected to the second driving assembly 140. The second guide member 133 is connected between the second movable member 131 and the back side 112 of the base 110, and is used to guide the first movable member 141 to move relative to the base 110 in a first direction to approach or move away from the first positioning assembly 120. The second driver 132 is disposed on one side of the back side 112 of the base 110, and is used to drive the second movable member 131 to move.

[0132] In this embodiment, the second guide member 133 is a slide rail and slider structure. In other embodiments, a guide column, guide sleeve structure or other structures may be used to guide the second movable member 131 to move relative to the base 110 .

[0133] In this embodiment, the second driver 132 is a second cylinder, which includes a second cylinder body and a second piston rod that can move relatively, the second cylinder body is fixed on the back side 112 of the base 110, and the free end of the second piston rod is fixedly connected to the second movable member 131. In other embodiments, the second driver 132 can also be an oil cylinder or an electric cylinder.

[0134] The second movable member 131 moves relative to the base 110 under the driving of the second driver 132 , thereby driving the second driving assembly 140 to move relative to the base 110 as a whole.

[0135] There is a gap between the second movable member 131 and the side wall of the mounting hole 113 in the first direction, and the gap is sufficient for the second movable member 131 to move relative to the base 110 in the first direction.

[0136] More specifically, the mounting hole 113 includes a first hole 1131 and a second hole 1132 that are spaced apart. The first hole 1131 and the second hole 1132 respectively penetrate the base 110 and are connected to the front side 111 and the back side 112 of the base 110. The second guide member 133 is disposed between the first hole 1131 and the second hole 1132. The second movable member 131 includes a first mounting portion 1311, a first bending portion 1312, a second bending portion 1313, a second mounting portion 1314, a first connecting portion 1315, and a second connecting portion 1316. The first mounting portion 1311 is disposed on the back side 112 of the base 110 and is connected to the second guide member 133. The first bending portion 1312 extends from the edge of the first mounting portion 1311 toward the base 110 side and is penetrated in the first hole 1131. The second bending portion 1313 extends from the edge of the first mounting portion 1311 toward the base 110 and is inserted into the second hole 1132. The second mounting portion 1314 is disposed on the side of the front face 111 of the base 110 and is in the shape of a strip, with two ends corresponding to the first hole 1131 and the second hole 1132, respectively. The first connecting portion 1315 extends from one end of the second mounting portion 1314 toward the base 110, passes through the first hole 1131 and is fixedly connected to the first mounting portion 1311. The second connecting portion 1316 extends from the other end of the second mounting portion 1314 toward the base 110, passes through the second hole 1132 and is fixedly connected to the first mounting portion 1311. The second driving assembly 140 is connected to at least one of the first bending portion 1312, the second bending portion 1313, the second mounting portion 1314, the first connecting portion 1315 and the second connecting portion 1316.

[0137] In this embodiment, two first guide members 144 are provided in the second driving assembly 140, and the two first guide members 144 correspond to the first bending portion 1312 and the second bending portion 1313 respectively, and the first movable member 141 is connected to the first bending portion 1312 and the second bending portion 1313 respectively through the two first guide members 144. Two elastic members 143 are provided in the second driving assembly 140, and the two elastic members 143 correspond to the first connecting portion 1315 and the second connecting portion 1316 respectively, one end of one elastic member 143 is connected to the first movable member 141, and the other end is connected to the first connecting portion 1315. One end of the other elastic member 143 is connected to the first movable member 141, and the other end is connected to the second connecting portion 1316. The first cylinder body 1421 in the first cylinder 142 is fixedly arranged on the second mounting portion 1314. The first cylinder 142 is ventilated, and the first movable member 141 drives the second positioning assembly 150 to move. The first cylinder 142 is de-energized, and the elastic member 143 drives the first movable member 141 to bring the second positioning assembly 150 back to its original position.

[0138] The specific structure of the first driving assembly 130 is described in detail above, and the third driving assembly 170 can be implemented by reference.

[0139] To reduce manufacturing costs, the first drive assembly 130 and the third drive assembly 170 may share a power device (the second drive 132 ).

[0140] like Figure 3 and Figure 8 As shown, specifically, the third driving assembly 170 includes a third movable member 171 and a third guide member (not visible in the figure). The third guide member is connected between the third movable member 171 and the base 110, and is used to guide the third movable member 171 to move relative to the base 110 in the second direction to approach or move away from the third positioning assembly 160. The fourth driving assembly 180 is arranged on the third movable member 171. Among them, the third movable member 171 is in transmission cooperation with the second movable member 131, so as to move under the drive of the second movable member 131, and when the second movable member 131 approaches the first positioning assembly 120, the third movable member 171 approaches the third positioning assembly 160, and when the second movable member 131 moves away from the first positioning assembly 120, the third movable member 171 moves away from the third positioning assembly 160.

[0141] The third driving assembly 170 is designed with reference to the first driving assembly 130, and a part of the third movable member 171 is also arranged on the back side 112 of the base 110. The difference is that there is no power device in the third driving assembly 170, and the third movable member 171 is driven and matched with the second movable member 131 to realize the sharing of the power device with the first driving assembly 130, thereby saving costs.

[0142] Specifically, the third movable member 171 is provided with a long groove 1711, which is located at a corner of the third movable member 171 adjacent to the second movable member 131 and extends toward the center of the third movable member 171. The second movable member 131 is provided with a roller 134 rotatable around its own axis, which is clamped in the groove 1711 and can roll back and forth along the extension direction of the groove 1711.

[0143] The roller 134 rolls in the groove 1711 , and the rolling friction is relatively small, which reduces the transmission resistance. In other embodiments, the groove 1711 can also be arranged on the second movable member 131 , and the roller 134 can be arranged on the third movable member 171 .

[0144] After the carrier 100 clamps the workpiece 10, it needs to drive the workpiece 10 to rotate so as to perform appearance inspection on different sides. During the rotation, centrifugal force is generated, and the clamping force (elastic force) provided by the second drive assembly 140 and the fourth drive assembly 180 may not be able to resist the centrifugal force, resulting in the workpiece 10 not being firmly fixed. Figure 3 As shown, the carrier 100 further includes a vacuum suction cup 101 , which is fixed to at least one of the base 110 , the first positioning assembly 120 and the second positioning assembly 150 , and is used to communicate with a negative pressure source (not shown) to absorb the workpiece 10 .

[0145] Furthermore, a plurality of vacuum suction cups 101 are provided on the front side of the base 110. The end surface of each vacuum suction cup 101 is used to carry and adsorb the workpiece 10. When clamping the workpiece 10, the workpiece 10 is placed above the plurality of vacuum suction cups 101, and after the second drive assembly 140 and the fourth drive assembly 180 clamp the workpiece 10, the vacuum suction cups 101 are controlled to adsorb the workpiece 10 to fix the workpiece 10. By providing a plurality of vacuum suction cups 101, the workpiece 10 can be firmly fixed.

[0146] In order to perform appearance inspection on the side surface of the workpiece 10 and the adjacent front and back portions, the carrier 100 should cover the workpiece 10 as little as possible when clamping the workpiece 10 .

[0147] Specifically, the first positioning assembly 120 is fixed on the base 110 , protrudes from the outer edge of the base 110 and extends outward, and the free end thereof is used to contact the side surface of the workpiece 10 .

[0148] The first positioning assembly 120 forms a cantilever beam structure, which reduces the shielding of the back side (the side facing the base 110 ) of the workpiece 10 .

[0149] More specifically, the first positioning assembly 120 includes a first cantilever 121 and a first positioning member 122. The first cantilever 121 protrudes from the outer edge of the base 110 and extends outward. The first positioning member 122 is fixed to the free end of the first cantilever 121 and is cylindrical, and its cylindrical surface is used to abut against the side of the workpiece 10.

[0150] The cylindrical surface abuts against the side surface of the workpiece 10 to form a line contact, thereby reducing the shielding of the side surface of the workpiece 10 by the first positioning component 120 .

[0151] Similarly, the second positioning assembly 150 is disposed on the second driving assembly 140, protruding from the outer edge of the base 110 and extending outward, and its free end is used to conflict with the side of the workpiece 10. More specifically, the second positioning assembly 150 includes a second cantilever 152 and a second positioning member 151. The second cantilever 152 is disposed on the second driving assembly 140, protruding from the outer edge of the base 110 and extending outward, and is used to move relative to the first positioning assembly 120 under the drive of the second driving assembly 140. The second positioning member 151 is fixed to the free end of the second cantilever 152, and is cylindrical, and its cylindrical surface is used to conflict with the side of the workpiece 10.

[0152] The beneficial effects of the specific structure of the second positioning assembly 150 are the same as those of the first positioning assembly 120 .

[0153] In this embodiment, the first positioning assembly 120 and the second positioning assembly 150 both adopt a cantilever beam structure. In other embodiments, one of them can be set as a cantilever beam structure as needed.

[0154] Similarly, the third positioning component 160 and the fourth positioning component 190 can also be executed with reference to the first positioning component 120, which will not be repeated here.

[0155] The fifth driving assembly 300 is described in detail below.

[0156] like Figure 1 As shown, the fifth drive assembly 300 includes a fifth driver 310 , a sixth driver 320 and a seventh driver 330 .

[0157] The carrier 100 is disposed on the fifth driver 310, and the fifth driver 310 is used to drive the carrier 100 to rotate around the third direction. The fifth driver 310 is disposed at the moving end of the sixth driver 320, and the sixth driver 320 is used to drive the fifth driver 310 to reciprocate in the second direction. The sixth driver 320 is disposed at the moving end of the seventh driver 330, and the seventh driver 330 is used to drive the sixth driver 320 to reciprocate in the first direction.

[0158] Through the above structure, the carrier 100 is driven to reciprocate in the first direction and the second direction, and to rotate around the third direction. Any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0159] The sixth driver 320 and the seventh driver 330 may be linear motors, and the fifth driver 310 may be a rotary cylinder.

[0160] Since the carrier 100 needs to rotate during operation, it is difficult to provide negative pressure to the vacuum suction cup 101 on the carrier 100 or to supply air to the cylinders (such as the first cylinder 142 and the second cylinder 132) on the carrier 100. For this purpose, the following design is made.

[0161] like Figure 3 and Fig. 9 As shown, the fifth driver 310 includes a fifth driver body 311 and a fifth driver end 312. The fifth driver end 312 is rotatably disposed on the fifth driver body 311 around its own axis and is fixedly connected to the base 110. The fifth driver assembly 300 also includes a rotating shaft 340 and a slip ring 350. The rotating shaft 340 is coaxially sleeved in the fifth driver end 312 and fixedly connected thereto, and has a plurality of openings. The slip ring 350 is fixedly connected to one end of the rotating shaft 340 that faces away from the base 110 and is in communication with the plurality of openings.

[0162] The fifth driving body 311 is disposed at the moving end of the sixth driver 320. The rotating shaft 340 can be fixed to the fifth driving end 312 by a latch. The opening on the rotating shaft 340 is used to communicate with the vacuum suction cup 101 or the cylinder on the carrier 100.

[0163] Slip ring is a prior art, used to form a medium channel between a fixed part and a rotating part to transmit vacuum or compressed gas. In this embodiment, the rotating part is the rotating shaft 340, and the fixed part is a high pressure gas source or a negative pressure source (not shown).

[0164] The appearance detection component 200 is described in detail below.

[0165] like Figure 1 and Fig.10 As shown, the appearance detection assembly 200 includes a support 210 , at least three first collection units 220 and at least three second collection units 230 .

[0166] Each first acquisition unit 220 is disposed on the support 210 and is used to capture an image of the workpiece 10. Among them, at least one first acquisition unit 220 is used to capture the front of the workpiece 10. At least one first acquisition unit 220 is used to capture the back of the workpiece 10. At least one first acquisition unit 220 is used to capture the side of the workpiece 10. Each second acquisition unit 230 is disposed on the support 210 and is used to scan the outer contour of the workpiece 10. Among them, at least one second acquisition unit 230 is used to scan the front of the workpiece 10. At least one second acquisition unit 230 is used to scan the back of the workpiece 10. At least one second acquisition unit 230 is used to scan the side of the workpiece 10.

[0167] In this embodiment, four first acquisition units 220 are provided. In the third direction, one of the first acquisition units 220 is provided at the lower part of the support 210, another is provided at the middle part, and the remaining two are provided at the upper part. The first acquisition unit 220 provided at the lower part of the support 210 is used to photograph the back side of the workpiece 10. The first acquisition unit 220 provided at the middle part of the support 210 is used to photograph the side of the workpiece 10. The two first acquisition units 220 provided at the upper part of the support 210 are spaced apart in the first direction and are used to photograph the front side of the workpiece 10.

[0168] In some application scenarios, the front surface of the workpiece 10 to be inspected is uneven (has a height difference in the third direction). For example, the workpiece 10 is the middle frame of a notebook computer, which has multiple raised buttons. The first acquisition unit 220 has a certain acquisition distance, so two first acquisition units 220 need to be set to shoot the front surface of the workpiece 10 to meet the inspection requirements.

[0169] In this embodiment, three second acquisition units 230 are provided. In the third direction, they are respectively located at the upper, middle and lower parts of the support 210 to scan the front, side and back of the workpiece 10 respectively.

[0170] To facilitate adjustment of the shooting position, each first acquisition unit 220 includes a fourth driver 221, a mounting plate 222, a camera 223, and a light source 224. The fourth driver 221 is disposed on the support 210. The mounting plate 222 is disposed at the driving end of the fourth driver 221, and is used to move under the drive of the fourth driver 221. The camera 223 is fixed on the mounting plate 222. The light source 224 is fixed on the mounting plate 222.

[0171] When the fourth driver 221 is in operation, it drives the mounting plate 222 to move, thereby adjusting the position of the camera 223 and further changing the shooting position.

[0172] Furthermore, the appearance inspection component 200 further includes a light source 240. The light source 240 is spaced apart from the first acquisition unit 220 for photographing the back of the workpiece 10 in the third direction to provide supplementary light from the front of the workpiece 10 to improve the photographing effect.

[0173] In summary, the carrier and the detection device of this embodiment have at least the following technical effects:

[0174] It is compatible with workpieces of various specifications and has high positioning accuracy.

[0175] The above are only implementation methods of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
