[0088] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0089] Figure 1 It is a schematic diagram of the three-dimensional structure of the workpiece to be detected in the embodiment of the detection device of the present application.
[0090] like Figure 1 As shown, the workpiece 10 to be inspected can be the upper cover, lower cover, or middle frame of a laptop computer. For ease of description, the workpiece 10 is abstracted into a rectangular block of a certain thickness, which includes a first surface 11 and a second surface 12 opposite to each other, and four side surfaces A, B, C, and D connecting the first surface 11 and the second surface 12.
[0091] Figure 2 It is a structural diagram of an embodiment of the detection device of the present application.
[0092] like Figure 1 and Figure 2 As shown, the inspection device 1000 is used to perform appearance inspection on the first surface 11 and the second surface 12 of the workpiece 10 .
[0093] The detection device 1000 of the present application may include a carrier 100 , a fifth driving assembly 300 , a mounting base 200 , a first collection assembly 400 , and a second collection assembly 500 .
[0094] The carrier 100 is used to hold a workpiece 10. When the workpiece 10 is clamped to the carrier 100, its first surface 11 faces away from the carrier 100, while its second surface 12 faces the carrier 100. The carrier 100 is provided with an opening 111 (see the detailed description of the carrier 100 below), which corresponds to the workpiece 10. At least a portion of the second surface 12 is exposed through the opening 111 to facilitate visual inspection.
[0095] The first collecting assembly 400 and the second collecting assembly 500 are spaced apart (in the Y direction) on the mounting base 200. The first collecting assembly 400 and the second collecting assembly 500 are both used to collect data representing the appearance characteristics of the workpiece 10.
[0096] The carrier 100 is mounted on the fifth drive assembly 300, with at least the opening 111 region suspended. Suspended specifically means that both sides of the vehicle are unobstructed in the Y direction. The carrier 100 is fixed to the driving end of the fifth drive assembly 300 in a manner similar to a cantilever beam. The fifth drive assembly 300 is used to drive the carrier 100 back and forth in the X and Z directions. The X, Z, and Y directions are perpendicular to each other.
[0097] As the carrier 100 passes through the gap, the first acquisition assembly 400 is used to collect data representing the appearance characteristics of the first surface 11 of the workpiece 10, with the first surface 11 facing the first acquisition assembly 400. The second acquisition assembly 500 is used to collect data representing the appearance characteristics of the second surface 12 of the workpiece 10, with the second surface 12 facing the second acquisition assembly 500.
[0098] The specific working process of the detection device 1000 is as follows:
[0099] The fifth driving assembly 300 drives the carrier 100 in the negative direction of the X direction ( Figure 2 The workpiece 10 clamped on the carrier 100 passes through the gap between the first collecting assembly 400 and the second collecting assembly 500, so that the first area of the workpiece 10 is detected;
[0100] The fifth driving assembly 300 drives the carrier 100 to move along the Z direction;
[0101] The fifth driving assembly 300 drives the carrier 100 in the positive direction of the X direction ( Figure 2 The workpiece 10 clamped on the carrier 100 passes through the gap between the first collecting assembly 400 and the second collecting assembly 500, so that the second area of the workpiece 10 is detected;
[0102] The above steps are repeated until all surfaces to be inspected of the workpiece 10 are inspected.
[0103] Figure 3 yes Figure 2 A-axis view in (rotated 90° counterclockwise). Figure 3 The specific structure of the carrier 100 is shown.
[0104] like Figure 3 As shown, the carrier 100 includes a base 110 , a first positioning assembly 120 , a first driving assembly 130 , a second driving assembly 140 , a second positioning assembly 150 , a third positioning assembly 160 , a third driving assembly 170 , a fourth driving assembly 180 and a fourth positioning assembly 190 .
[0105] The first positioning assembly 120 is fixed to the base 110. The first drive assembly 130 is disposed on the base 110. The second drive assembly 140 is disposed on the first drive assembly 130. The second positioning assembly 150 is disposed on the second drive assembly 140. The first drive assembly 130 is used to drive the second drive assembly 140 to move relative to the first positioning assembly 120, and the second drive 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 (clamping the workpiece 10 from both sides A and B).
[0106] The third positioning assembly 160 is fixed to the base 110. The third drive assembly 170 is disposed on the base 110. The fourth drive assembly 180 is disposed on the third drive assembly 170. The fourth positioning assembly 190 is disposed on the fourth drive assembly 180. The third drive assembly 170 is used to drive the fourth drive assembly 180 to move relative to the third positioning assembly 160, and the fourth drive 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 (clamping the workpiece 10 from both sides of side C and D), and the movement direction of the fourth positioning assembly 190 relative to the third positioning assembly 160 is different from the movement direction of the second positioning assembly 150 relative to the first positioning assembly 120.
[0107] The second positioning assembly 150 moves in a first direction relative to the first positioning assembly 120. The fourth positioning assembly 190 moves in a 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 can also be arranged at an angle.
[0108] In addition, the base 110 is provided with an opening 111 extending therethrough. The opening 111 is adapted to correspond to the workpiece 10. At least a portion of the second surface 12 of the workpiece 10 is exposed through the opening 111, so that the second acquisition assembly 500 can acquire data.
[0109] The base 110 is generally rectangular and has four sides a, b, c, and d. After the workpiece 10 is clamped to the carrier 100, the four sides a, b, c, and d of the base 110 correspond to the four side faces A, B, C, and D of the workpiece 10, respectively. The first positioning assembly 120, the second positioning assembly 150, the fourth positioning assembly 190, and the third positioning assembly 160 are respectively disposed on the four sides a, b, c, and d of the base 110.
[0110] Two first positioning assemblies 120 are spaced apart on the frame a of the base 110. Two second positioning assemblies 150 (partially connected) are positioned on the frame b of the base 110. Two third positioning assemblies 160 are spaced apart on the frame d of the base 110. A fourth positioning assembly 190 is positioned on the frame c of the base 110. The specific number of first positioning assemblies 120, second positioning assemblies 150, third positioning assemblies 160, and fourth positioning assemblies 190 can be adjusted according to specific needs.
[0111] The working principle and working process of this embodiment will be specifically described below using the 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.
[0112] 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.
[0113] Figure 4 The dotted lines in the figure represent the extreme positions of the second driving assembly 140 and the second positioning assembly 150, respectively.
[0114] like Figure 4 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 50 mm, which can generally be compatible with different workpieces 10 whose sizes fluctuate within the range of 50 mm. The second predetermined range B can be 10 mm. The above-mentioned A, B, L1, L2, L3, L4 and the following L0 are all dimensions in the first direction.
[0115] Refer to the following Figure 3 and Figure 4 Introduce the installation and clamping process:
[0116] 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, the distance L0 between the side surfaces A and B of the workpiece 10 is greater than L3 and smaller than L4.
[0117] The second driving assembly 140 drives the second positioning assembly 150 away from the first positioning assembly 120 .
[0118] (Place the workpiece 10 on the vacuum chuck 101 , see below for the vacuum chuck 101 ) Using the first positioning assembly 120 as a reference, place the side A of the workpiece 10 against the first positioning assembly 120 to define the position of the workpiece 10 on the base 110 .
[0119] 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 B of the workpiece 10 , thereby clamping the workpiece 10 from both sides A and B.
[0120] In this embodiment, the first driving assembly 130 enables the carrier 100 to be compatible with workpieces 10 of different specifications.
[0121] Figure 5 yes Figure 3 Magnified view of the detail view.
[0122] like Figure 3 and Figure 5 As shown, when the movement direction of the second drive assembly 140 relative to the first positioning assembly 120 forms an acute angle with the first direction, the movement will also produce a movement in the first direction (the spacing direction between the side surfaces A and B of the workpiece 10). Similarly, when the movement direction of the second positioning assembly 150 relative to the first positioning assembly 120 forms an acute angle with the first direction, the movement will also produce a movement in the first direction. However, to improve clamping efficiency, in this embodiment, the second drive assembly 140 and the second positioning assembly 150 move in the same direction (the first direction) relative to the first positioning assembly 120. Similarly, the fourth drive assembly 180 and the fourth positioning assembly 190 move in the same direction (the second direction) relative to the third positioning assembly 160.
[0123] The specific structure of the second driving assembly 140 is introduced below, and the fourth driving assembly 180 can be implemented accordingly.
[0124] like Figure 3 and 5 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 .
[0125] 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 move toward or 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 toward the first positioning assembly 120. The second positioning assembly 150 is fixed to the first movable member 141.
[0126] In this embodiment, the first guide member 144 is a slide rail and slider structure. In other embodiments, a guide post, 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 .
[0127] In this embodiment, the first actuator 142 is disposed on the side of the first movable member 141 facing the first positioning assembly 120. The first actuator 142 is a first pneumatic cylinder comprising a first cylinder body and a first piston rod that are movable relative to each other. The first cylinder body is fixed to the first driving assembly 130, and the free end of the first piston rod is configured to abut against the first movable member 141. In other embodiments, the first actuator 142 may also be an oil cylinder or an electric cylinder.
[0128] 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.
[0129] 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 .
[0130] 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 .
[0131] After the side A 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 B of the workpiece 10 under the elastic force of the elastic member 143 , thereby clamping the workpiece 10 .
[0132] 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 , so as to drive the first movable member 141 away from the first positioning assembly 120 .
[0133] The workpiece 10 is removed.
[0134] 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 .
[0135] The second driving assembly 140 clamps the workpiece 10 through elastic force, and the clamping force is constant and adjustable, thereby avoiding damage to the workpiece 10 .

[0137] Figures 5 to 7 The relative positional relationship among the first driving assembly 130 , the second driving assembly 140 and the base 110 is shown.
[0138] like Figures 5 to 7 As shown, in order to make the connection structure among the first driving assembly 130 , the second driving assembly 140 and the base 110 more compact to save space, the first driving assembly 130 and the second driving assembly 140 can be respectively arranged on both sides of the base 110 .
[0139] The base 110 has a front face 111 and a back face 112, each with a mounting hole 113 extending therethrough. The mounting hole 113 connects the front face 111 and the back face 112 of the base 110. A second drive assembly 140 is disposed on the front face 111 of the base 110. A portion of the second movable member 131 is located on the back face 112 of the base 110, while the other portion extends through the mounting hole 113 and connects to the second drive assembly 140.
[0140] Specifically, the first driving assembly 130 includes a second movable member 131 , a second guide member 133 and a second driver 132 .
[0141] A portion of the second movable member 131 is located on the back side 112 of the base 110, while the other portion extends through the mounting hole 113 and is connected to the second driving assembly 140. A 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 second movable member 131 relative to the base 110 in a first direction to move toward or away from the first positioning assembly 120. A second driver 132 is provided on the back side 112 of the base 110 and is used to drive the second movable member 131 to move.
[0142] In this embodiment, the second guide member 133 is a slide rail and slider structure. In other embodiments, a guide post, guide sleeve structure or other structures may be used to guide the second movable member 131 to move relative to the base 110 .
[0143] In this embodiment, the second actuator 132 is a second pneumatic cylinder comprising a second cylinder body and a second piston rod that are relatively movable. The second cylinder body is fixed to the back surface 112 of the base 110, and the free end of the second piston rod is fixed to the second movable member 131. In other embodiments, the second actuator 132 may also be an oil cylinder or an electric cylinder.
[0144] The second movable member 131 moves relative to the base 110 under the driving of the second driver 132 , thereby driving the entire second driving assembly 140 to move relative to the base 110 .
[0145] There is a gap between the second movable member 131 and the sidewall of the mounting hole 113 in the first direction. The gap is sufficient for the second movable member 131 to move relative to the base 110 in the first direction.
[0146] 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 connect the front 111 and back 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 112 side 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 and is disposed in the first hole 1131. The second bent 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 front side 111 of the base 110 and is in the shape of an elongated strip, with its 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 bent portion 1312, the second bent portion 1313, the second mounting portion 1314, the first connecting portion 1315, and the second connecting portion 1316.
[0147] 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. 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. The other elastic member 143 has one end connected to the first movable member 141, and the other end is connected to the second connecting portion 1316. The first cylinder body in the first cylinder is fixed to the second mounting portion 1315. The first cylinder is ventilated, and the first movable member 141 drives the second positioning assembly 150 to move. When the second cylinder stops working, the elastic member 143 drives the first movable member 141 to bring the second positioning assembly 150 back to its original position.
[0148] The specific structure of the first drive assembly 130 is described in detail above. The third drive assembly 170 (see Figure 3 ) can be used as a reference for implementation.
[0149] like 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. The provision of the vacuum suction cup 101 can make the workpiece 10 more firmly fixed.
[0150] Furthermore, multiple 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 support and hold the workpiece 10. When clamping the workpiece 10, the workpiece 10 is placed above the multiple vacuum suction cups 101. After the second drive assembly 140 and the fourth drive assembly 180 clamp the workpiece 10, the vacuum suction cups 101 are controlled to hold the workpiece 10 in place.
[0151] like Figure 3 As shown, to expose as much of the second surface 12 of the workpiece 10 as possible through the opening 111 , the opening 111 is disposed between the first positioning assembly 120 and the second positioning assembly 150 . Similarly, the opening 111 is disposed between the fourth positioning assembly 190 and the third positioning assembly 160 .
[0152] Furthermore, the first positioning assembly 120 extends toward the center of the opening 111 , and a free end thereof is configured to abut against a side surface of the workpiece 10 .
[0153] Compared with the frame a of the base 110 , the free end of the first positioning component 120 can significantly reduce the shielding of the second surface 12 of the workpiece 10 .
[0154] Furthermore, the first positioning assembly 120 includes a first overhang 121 and a first positioning member 122. The first overhang 121 is fixed to the base 110 and extends toward the center of the opening 111. The first positioning member 122 is fixed to the free end of the first overhang 121 and is cylindrical, with its cylindrical surface being configured to contact the side surface of the workpiece 10.
[0155] The cylindrical surface contacts the side of the workpiece 10 to form a line contact, thereby reducing the obstruction of the side of the workpiece 10 by the first positioning assembly 120. At the same time, the first positioning assembly 120 forms a point contact with the edge of the workpiece 10 on the first surface 11 or the second surface 12 of the workpiece 10.
[0156] Similarly, the second positioning assembly 150 extends toward the center of the opening 111, with its free end configured to contact the side of the workpiece 10. The second positioning assembly 150 includes a second overhang 151 and a second positioning member 152. The second overhang 151 is disposed on the second drive assembly 140 and extends toward the center of the opening 111, configured to move relative to the first positioning assembly 120 under the drive of the second drive assembly 140. The second positioning member 152 is fixed to the free end of the second overhang 151 and is cylindrical, with its cylindrical surface configured to contact the side of the workpiece 10.
[0157] The beneficial effects of the specific structure of the second positioning assembly 150 are the same as those of the first positioning assembly 120 .
[0158] 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 also be configured as a cantilever beam structure as needed.
[0159] 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.
[0160] See also Figure 2 , the first acquisition component 400 is introduced in detail below.

The first light source 440 is fixed to the drive end of the sixth drive assembly 420 and is closer to the second acquisition assembly 500 than the first camera 430. The sixth drive assembly 420 is used to drive the first camera 420 and the first light source 440 toward or away from the second acquisition assembly 500.
[0165] The first camera 430 is provided to increase the detection method of the first acquisition component 400. The sixth drive component 420 can be a ball screw pair, and the acquisition area of the first camera 430 is adjusted by the sixth drive component 420.
[0166] See also Figure 2 , the second acquisition component 500 is introduced in detail below.
[0167] like Figure 2 As shown, the second acquisition component 500 includes a second scanner 510. The second scanner 510 is used to scan the second surface 12 of the workpiece 10. The second scanner 510 can be a laser scanner.
[0168] To improve scanning efficiency, the second acquisition assembly 500 includes multiple second scanners 510. The multiple second scanners 510 are spaced apart (in the Z direction) so that when the carrier 100 passes through the gap, the projections of the multiple second scanners 510 on the carrier 100 are spaced apart in a direction perpendicular to the movement of the carrier 100.

[0175] The fixing base 560 is fixed to the second movable end 550. In this embodiment, the fixing base 560 is a separate component. In other embodiments, the fixing base 560 can also be a part of the second movable end 550.

[0177] The third light source 580 has a circular ring shape and is fixed to the fixing base 560 , and is further away from the first collection assembly 400 than the plurality of second light sources 570 .
[0178] The second camera 590 is fixed on the fixing base 560 and is further away from the first collecting assembly 400 than the third light source 580 , and is used to photograph the second surface 12 of the workpiece 10 .
