[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figure 1 and Figure 2 As shown, the utility model provides an automated visual inspection device for ceramic substrates, which includes a plug loading mechanism 10, a substrate loading mechanism 20, a lifting mechanism 30, a visual inspection mechanism 40, a marking mechanism 50, a substrate unloading mechanism 60, a plug unloading flip assembly 70 and a pushing mechanism 80.

[0028] The jam loading mechanism 10 includes a jam loading line 11, a jam transfer assembly 12 and a jam loading flip assembly 13 which are arranged in sequence. The jam loading line 11 is preferably a belt line. The jam transfer assembly 12 is used to transfer the jam loaded with substrates on the jam loading line 11 to the jam loading flip assembly 13. The jam transfer assembly 12 includes a linear module 121 and a first jam clamp 122 and a second jam clamp 123 driven by the linear module 121. A jam lifting module is also provided between the first jam clamp 122 and the second jam clamp 123 and the linear module 121.

[0029] The working process of the jam transfer assembly 12 is as follows: after the jam loading line 11 transports the fully loaded jam to its end and stops, the first jam clamp 122 moves to the top of the jam; the first jam clamp 122 opens, and the jam lifting module drives the first jam clamp 122 to descend to a suitable height; the first jam clamp 122 clamps the jam, and the jam lifting module drives the first jam clamp 122 to move to the highest position; the linear module 121 moves the first jam clamp 122 to the top of the jam loading flip assembly 13, and the jam lifting module drives the first jam clamp 122 to descend to a suitable height, the first jam clamp 122 releases the jam and rises, and the jam linear module 121 moves the first jam clamp 122 to a safe position for standby. The second jam clamp 123 is used to move the empty jam that has been loaded to the jam unloading flip assembly 70, and then collect the substrates that have been tested.

[0030] Please refer to Figure 3As shown, the plug loading and flipping assembly 13 includes a first bracket 131, a lifting module and a flipping module, and the lifting module drives the flipping module to rise or fall relative to the first bracket 131. Specifically, the lifting module includes a lifting motor 132, a transmission screw 133 and a second bracket 134 driven by the transmission screw 133 arranged on the first bracket 131, and a slide rail 1311 is arranged on the first bracket 131 for the second bracket 134 to slide up and down. The flipping module includes a flipping motor 135, a flipping bracket 136, a roller group 137 and a clamping part 138 arranged on the second bracket 134. The flipping motor 135 drives the flipping bracket 136 to rotate, and the roller group 137 is two groups, which are arranged side by side on both sides of the flipping bracket 136. The clamping part 138 is arranged on both sides of the flipping bracket 136 and can be close to each other to clamp the plug on the flipping bracket 137.

[0031] The working process of the plug loading and flipping assembly 13 is as follows: first, the flipping bracket 136 of the plug loading and flipping assembly 13 is flipped to a horizontal position, the plug transferring assembly 12 places the plug on the flipping bracket 136, and the clamping part 138 clamps and fixes the two sides of the plug, and at this time the opening of the plug faces upward; the flipping bracket 136 rotates until it reaches a vertical position, and at this time the opening of the plug faces the substrate loading line 21; the lifting module drives the flipping module to descend, and the substrate stops when it descends to the height of the substrate loading line 21, and the substrate loading line 21 takes the substrate away; the height of each substrate is adjusted in turn to align it with the substrate loading line 21 until all substrates in the plug are taken away; the lifting module drives the flipping module to rise to the flipping height, and after flipping, the plug transferring assembly 12 takes away the empty plug.

[0032] Please refer to Figure 1 and Figure 2 As shown, the substrate loading mechanism 20 includes a substrate loading line 21 and a substrate transfer assembly 22. The substrate loading line 21 is preferably a belt line, which is used to transfer the substrates stuck in the jam on the jam loading flip assembly 13 one by one. The substrate transfer assembly 22 is used to grab the substrate on the substrate loading line 21 to the lifting mechanism 30. The substrate transfer assembly 22 specifically includes a linear module 221 and a first substrate clamp 222 and a second substrate clamp 223 provided on the linear module 221. A clamp lifting module is also provided between the first substrate clamp 222 and the second substrate clamp 223 and the linear module 221. The first substrate clamp 222 is lifted and lowered by one of the clamp lifting modules, and the second substrate clamp 223 is lifted and lowered by the other clamp lifting module. The first substrate clamp 222 and the second substrate clamp 223 act independently.

[0033] The working process of the substrate loading mechanism 20 is as follows: when the substrates flow one by one from the plug loading flip assembly 13 to the end of the substrate loading line 21, the first substrate clamp 222 of the substrate transfer assembly 22 moves to the top of the substrate and opens, and the clamp lifting module drives the first substrate clamp 222 to descend. After reaching the substrate position, the first substrate clamp 222 clamps and then lifts; the first substrate clamp 222 moves to the top of the lifting mechanism 30; the clamp lifting module drives the first substrate clamp 222 to descend and places the substrate on the lifting mechanism 30.

[0034] Please refer to Figure 2 , Figures 4 to 6 As shown, the lifting mechanism 30 is located between the substrate transfer assembly 22 and the visual inspection mechanism 40. The lifting mechanism 30 includes a lifting platform 31, a lifting cylinder 33, and a cylinder mounting plate 32. The lifting platform 31 is lifted and lowered under the drive of the lifting cylinder 33. The lifting platform 31 is also provided with a plurality of cushion blocks 34 and sensors 35. The plurality of cushion blocks 34 are evenly distributed on the upper surface of the lifting platform 31. A groove is provided on the upper surface of the lifting platform 31. The sensor 35 is provided in the groove and does not protrude from the upper surface of the lifting platform 31. The sensor 35 is used to sense whether there is a substrate on the lifting platform 31.

[0035] The visual inspection mechanism 40 includes a line scanning platform 41 for carrying a substrate, a moving assembly 42 for driving the line scanning platform 41 to move, and a visual assembly 43 for inspecting the substrate. The line scanning platform 41 is provided with a clearance opening 410 adapted to the lifting platform 31, and the lifting platform 40 transfers the substrate on it to the line scanning platform 41 through a lifting action. The line scanning platform 41 includes a platform body 411 provided on the moving assembly 42 and two supporting arms 412 provided on one side of the platform body 411, and the clearance opening 410 is located between the two supporting arms 412. A plurality of supporting plates 413 are provided on opposite sides of the two supporting arms 412, respectively, and the supporting plates 413 include a supporting portion 4131 and a guiding portion 4132 for guiding the edge of the substrate to the supporting portion 4131. In this way, when the lifting platform 40 descends to place the substrate, the guiding portion 4132 can smoothly transfer the substrate to the supporting portion 4131, which allows the substrate to be positioned quickly and automatically on the one hand, and prevents the edge of the substrate from being damaged on the other hand. In the present invention, the supporting plate 413 is fixed to the supporting arm 412 by bolts. Preferably, a mounting groove 4121 for mounting the supporting plate 413 is provided on the supporting arm 412 .

[0036] The line scanning platform 41 is provided with a plurality of limit blocks 414. In this embodiment, there are four limit blocks 414, two of which are located on the side of the platform body 411 facing the clearance opening 410, and the other two limit blocks 414 are respectively located at the ends of the two supporting arms 412, that is, at the other side of the clearance opening 410. When the substrate is placed on the line scanning platform 41 by the lifting platform 31, the two sides of the substrate close to the supporting arms 412 are respectively placed on the supporting plates 413, and the other two sides of the substrate are limited by the limit blocks 414 to prevent the substrate from shaking during the movement of the line scanning platform 41.

[0037] Please also refer to Figure 7 As shown, the visual component 43 includes a plurality of cameras (431a, 431b, 431c) and a plurality of light sources (432a, 432b, 432c) located above the moving path of the line scanning platform 41, and a plurality of cameras (431d, 431e, 431f) and a plurality of light sources (432d, 432e, 432f) located below the moving path of the line scanning platform 41. In other embodiments, the number and position of the cameras and light sources can be set on the moving path of the line scanning platform 41 according to actual needs, which is not limited here.

[0038] The working process of the visual inspection mechanism 40 is as follows: the line scanning platform 41 moves to the lifting mechanism 30, and the clearance opening 410 is positioned below the lifting platform 31. The lifting cylinder 33 is retracted, and the substrate is lowered onto the line scanning platform 41; the line scanning platform 41 is driven by the moving component 42 to sequentially pass through multiple camera inspection stations for visual inspection, and the camera inspection stations are staggered to prevent interference.

[0039] Please refer to Figure 2 As shown, the marking mechanism 50 includes a marking line 52, a material-taking clamping claw assembly 51 for grabbing the substrate on the line scanning platform 41 to the marking line 52, and a code scanning assembly 53 and a laser marking assembly 54 arranged on the marking line 52 in sequence. The material-taking clamping claw assembly 51 includes a clamping claw module 511 and a linear module 512 for driving the clamping claw module 511 to move, and the linear module 512 is horizontally arranged above the moving assembly 42 and one end of the marking line 52. The working process of the marking mechanism 50 is as follows: the material-taking clamping claw assembly 51 grabs the substrate on the line scanning platform 41 to the marking line 52, and passes through the code scanning assembly 53 and the laser marking assembly 54 on the marking line 52 in sequence to perform code scanning and laser marking.

[0040] The substrate unloading mechanism 60 is used to unload the substrate after inspection. The substrate unloading mechanism 60 includes a substrate unloading line and a substrate transfer assembly 22. The substrate unloading line includes an OK line 61 and an NG line 62. The OK line 61 is used to unload the substrate with an OK inspection result, and the NG line 62 is used to unload the substrate with an NG inspection result. The substrate loading line 21, the OK line 61, and the NG line 62 are arranged side by side, and the substrate transfer assembly 22 is arranged horizontally above the substrate loading line 21, the OK line 61, and the NG line 62. The second substrate clamp 223 of the substrate transfer assembly 22 is used to grab the substrate on the marking line 52 to the OK line 61 or the NG line 62.

[0041] There are two jammer unloading and flipping assemblies 70, which are connected to the OK line 61 and the NG line 62 respectively. The jammer unloading and flipping assemblies 70 are used to flip the empty jammers on it to a position where the opening faces the OK line 61 and the NG line and collect the inspected substrates flowing out of the visual inspection mechanism 40. The jammer transfer assembly 12 is horizontally arranged on the jammer loading line 11, the jammer loading and flipping assembly 13 and the jammer unloading and flipping assemblies 70. The second jammer clamp 123 of the jammer transfer assembly 12 grabs the empty jammer on the jammer loading and flipping assembly 13 to the jammer unloading and flipping assemblies 70. The specific structure of the jammer unloading and flipping assemblies 70 is substantially the same as that of the jammer loading and flipping assemblies 13, and will not be described in detail here.

[0042] The material pushing mechanism 80 is disposed between the two jamming material unloading flipping assemblies 70.

The rotary motor 86 is used to drive the push plate 85 to rotate left and right, and the slide cylinder 82 drives the rotary motor 86 to move in a direction perpendicular to the rotation plane of the push plate 85 (i.e., the front and rear direction). A slide rail 83 is disposed on the bracket 81 in the front and rear direction, and a slider 84 is disposed on the mounting frame 87 to slide with the slide rail 83.

[0043] The working process of the pushing mechanism 80 is as follows: the slide cylinder 82 drives the rotating motor 86 to move to the front end, at which time the push plate 85 is in a vertical position; when the jammer on the jammer unloading and flipping assembly 70 connected to the OK line 61 or the NG line 62 is full and flipped to the position where the opening faces upward, the rotating motor 86 drives the push plate 85 to rotate 90° to the left or right, and the stopper moves to the front of the jammer; the slide cylinder 82 drives the rotating motor 86 and the push plate 85 to move backward to push the jammer out of the jammer unloading and flipping assembly 70.
