Description

Technical Field

[0001] This application relates to the field of laser marking technology, and in particular to a conveying device and marking equipment. Background Technology

[0002] To achieve continuous product marking, automatic product loading and unloading are required. To prevent products from bumping or colliding during transport, they are placed in a tray. During processing, the stacked trays are placed one by one onto the conveyor line. After the conveyor line transports the trays to the set position, a transfer device removes the products from the trays and transfers them to the marking device for marking. After marking, the products are returned to the trays. Once all products in the trays have been marked, the conveyor line continues to transport trays, completing the stacking of trays at the end of the conveyor line.

[0003] In related technologies, the conveyor lines simply stop the conveyor trays, resulting in significant uncertainty in the trays' position. This can easily interfere with the picking and unloading of products from the trays. Utility Model Content

[0057] Reference Figures 1 to 3 According to a first aspect embodiment of this application, the conveying device includes a conveyor line 110, a first positioning module 300, and an interception module 400. The conveyor line 110 is used to convey a tray 120, which is used to carry a product 130. The area through which the tray 120 is conveyed by the conveyor line 110 is defined as a first area.

[0058] The interception module 400 includes an interceptor 420 and a first drive assembly 410. The first drive assembly 410 is used to drive the interceptor 420 into a first area so that the interceptor 420 stops the tray 120. The first drive assembly 410 is also used to drive the interceptor 420 out of the first area.

[0059] The first positioning module 300 includes a second drive assembly 310, a first positioning element 320, and a second positioning element 330. The first positioning element 320 and the second positioning element 330 are spaced apart. The second drive assembly 310 is used to drive the first positioning element 320 and the second positioning element 330 to move closer together, so that the first positioning element 320 and the second positioning element 330 clamp the tray 120 stopped by the interceptor 420. The second drive assembly 310 is also used to drive the first positioning element 320 and the second positioning element 330 away from each other.

[0060] The conveying device according to the embodiments of this application has at least the following beneficial effects: by adding a first positioning module 300, the first positioning member 320 and the second positioning member 330 can clamp the tray 120 stopped by the interceptor 420, thereby realizing the stopping and positioning of the tray 120 in the conveying line 110, which is beneficial to the accurate picking and unloading of the product 130 in the tray 120.

[0061] It should be noted that the first region is a spatial area defined by the longitudinal contour of the tray 120 along the conveying direction of the conveyor line 110. The product 130 can be a glass block or a plastic sheet.

[0062] Specifically, the conveyor line 110 includes a sixth drive assembly 111 and a conveyor belt 112. The sixth drive assembly 111 drives the conveyor belt 112 to rotate, and the conveyor belt 112 supports the material tray 120. The sixth drive assembly 111 can be a motor-driven synchronous pulley, and the conveyor belt 112 is a synchronous belt meshing with the synchronous pulley; the sixth drive assembly 111 can also be a motor-driven sprocket and chain mechanism, and the conveyor belt 112 is tensioned by the shaft of the sprocket.

[0063] Specifically, the first drive assembly 410 includes a first cylinder 411, the first cylinder body of which is fixed to the frame 140, and the first piston rod of which is fixedly connected to the interceptor 420. When the first cylinder 411 is vented, it drives the interceptor 420 upward, thereby causing the interceptor 420 to enter the first region. When the first cylinder 411 drives the interceptor 420 downward, it drives the interceptor 420 away from the first region.

[0064] In another embodiment, the first drive component 410 may also be one of the following: a hydraulic cylinder, a linear motor, a motor-driven gear and rack mechanism, a motor-driven crank-slider mechanism, a motor-driven lead screw and nut mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven sprocket and chain mechanism.

[0065] It should be noted that the second drive assembly 310 drives the first positioning member 320 and the second positioning member 330 to move closer to each other. That is, the first positioning member 320 can be fixed to the frame 140, and the second drive assembly 310 can drive the second positioning member 330 to move, so that the second positioning member 330 moves closer to the first positioning member 320. Alternatively, the second drive assembly 310 can move the first positioning member 320 and the second positioning member 330, so that the first positioning member 320 and the second positioning member 330 move closer to each other.

[0066] Specifically, the second drive assembly 310 includes two second cylinders 311. The second cylinder bodies of both second cylinders 311 are fixed to the frame 140. The second piston rod of one second cylinder 311 is fixedly connected to the first positioning member 320, and the second piston rod of the other second cylinder 311 is connected to the second positioning member 330. The movement directions of the second piston rods of the two second cylinders 311 are opposite. Therefore, when compressed gas is introduced into the two second cylinders 311, it can drive the first positioning member 320 and the second positioning member 330 to move closer together or further apart.

[0067] In another embodiment, the second cylinder 311 may also be replaced by one of the following: a hydraulic cylinder, a linear motor, a motor-driven rack and pinion mechanism, a motor-driven crank-slider mechanism, a motor-driven lead screw and nut mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven sprocket and chain mechanism.

[0068] Reference Figure 1 In some embodiments of this application, the direction of the conveyor line 110 conveying the material tray 120 is set as the first direction, and the angle between the second direction and the first direction is set to be greater than zero. The second drive assembly 310 is used to drive the first positioning member 320 and the second positioning member 330 to move closer to each other along the second direction.

[0069] By bringing the first positioning member 320 and the second positioning member 330 closer together along the second direction, and combining the positioning of the tray 120 by the interceptor 420, it is beneficial to determine the position of the tray 120 on the horizontal plane.

[0070] Specifically, the angle between the second direction and the first direction can be 45 degrees, 60 degrees, 75 degrees, 80 degrees, 90 degrees, or other angles. Preferably, the angle between the second direction and the first direction is 90 degrees. (Refer to...) Figure 1 For example, the second direction is the left and right direction, and the first direction is the backward direction.

[0071] Reference Figures 1 to 4In the improved embodiment described above, the conveying device further includes a limiting module 200. The tray 120 includes a first side 121 and a second side 122 facing each other. The interceptor 420 is used to abut against the first side 121. The limiting module 200 includes a third driving assembly 210 and a limiting member 220. The third driving assembly 210 is used to drive the limiting member 220 into the first region so that the limiting member 220 abuts against the second side 122. The third driving assembly 210 is also used to drive the limiting member 220 away from the first region.

[0072] With the cooperation of the interceptor 420 and the limiter 220, the position of the tray 120 in the second direction is completely determined, and the positioning of the tray 120 in the second direction is more accurate.

[0073] Specifically, the third drive assembly 210 includes a third cylinder 211, the third cylinder body of which is fixed to the frame 140, and the third piston rod of which is fixedly connected to the interceptor 420. When the third cylinder 211 is ventilated, it drives the interceptor 420 to move in a rear-upward direction, thereby causing the interceptor 420 to enter the first region. When the third cylinder 211 drives the interceptor 420 to move in a front-downward direction, it drives the interceptor 420 to leave the first region.

[0074] In another embodiment, the third drive component 210 may also be one of the following: a hydraulic cylinder, a linear motor, a motor-driven rack and pinion mechanism, a motor-driven crank-slider mechanism, a motor-driven lead screw and nut mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven sprocket and chain mechanism.

[0075] Reference Figure 4 In the improved embodiment described above, the angle between the third direction and the horizontal plane is set to be greater than zero, and the third driving component 210 is used to drive the limiting member 220 to enter or leave the first region along the third direction.

[0076] By making the angle between the third direction and the horizontal plane greater than zero, when the limiting member 220 moves along the third direction, it has a motion component along the second direction. Thus, the limiting member 220 can push the material tray 120, thereby accurately positioning the position of the material tray 120 in the second direction.

[0077] Specifically, the angle between the third direction and the horizontal plane can be 30 degrees, 45 degrees, 60 degrees, or other angles.

[0078] Reference Figure 1In some embodiments of this application, the conveying module further includes a second positioning module 500. Assuming the direction of the conveyor line 110 conveying the material tray 120 is a first direction, the first positioning module 300 and the second positioning module 500 are sequentially arranged along the first direction. The second positioning module 500 includes a fourth driving component 510, a third positioning element 520, and a fourth positioning element 530. The fourth positioning element 530 and the third positioning element 520 are spaced apart.

[0079] The fourth drive assembly 510 is used to drive the third positioning member 520 and the fourth positioning member 530 to move closer together, so that the third positioning member 520 and the fourth positioning member 530 clamp the tray 120 conveyed by the conveyor line 110. The fourth drive assembly 510 is also used to drive the third positioning member 520 and the fourth positioning member 530 away from each other.

[0080] By setting the second positioning module 500, the material tray 120 can be positioned before material collection, which is beneficial for accurately collecting the material tray 120.

[0081] It should be noted that the fourth drive assembly 510 drives the third positioning member 520 and the fourth positioning member 530 to move closer to each other. That is, the third positioning member 520 can be fixed to the frame 140, and the fourth drive assembly 510 can drive the fourth positioning member 530 to move, so that the fourth positioning member 530 moves closer to the third positioning member 520. Alternatively, the fourth drive assembly 510 can move the third positioning member 520 and the fourth positioning member 530, so that the third positioning member 520 and the fourth positioning member 530 move closer to each other.

[0082] Specifically, the fourth drive assembly 510 includes two fourth cylinders 511. The cylinder bodies of both fourth cylinders 511 are fixed to the frame 140. The fourth piston rod of one fourth cylinder 511 is fixedly connected to the third positioning member 520, and the fourth piston rod of the other fourth cylinder 511 is connected to the fourth positioning member 530. The fourth piston rods of the two fourth cylinders 511 move in opposite directions. Therefore, when compressed gas is introduced into the two fourth cylinders 511, it can drive the third positioning member 520 and the fourth positioning member 530 to move closer together or further apart.

[0083] In another embodiment, the fourth cylinder 511 may be replaced by one of the following: a hydraulic cylinder, a linear motor, a motor-driven rack and pinion mechanism, a motor-driven crank-slider mechanism, a motor-driven lead screw and nut mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven sprocket and chain mechanism.

[0084] Reference Figure 5 and Figure 6In some embodiments of this application, the conveying device further includes a transfer module 600, which includes a picking member 610 and a fifth drive assembly 620. The picking member 610 is used to pick up or release the product 130. The fifth drive assembly 620 is used to drive the picking member 610 closer to or further away from the tray 120 clamped by the first positioning member 320 and the second positioning member 330.

[0085] By setting up the transfer module 600, the product 130 to be processed on the tray 120 can be removed, and the processed product 130 can be placed back on the tray 120. The conveying device can automatically complete the loading and unloading of the product 130, and the conveying device has a higher degree of automation.

[0086] Reference Figure 5 and Figure 6 In the improved embodiment described above, the transfer module 600 further includes a camera 630, which is used to acquire images of at least one of the product 130 and the tray 120. The fifth drive component 620 is also used to drive the camera 630 and the picking component 610 to move synchronously on a horizontal plane.

[0087] By setting a camera 630 that moves synchronously with the picking component 610 on a horizontal plane, it is possible to acquire images of at least one of the product 130 and the tray 120, thereby enabling precise positioning of at least one of the product 130 and the tray 120, which in turn facilitates the picking component 610 to accurately pick up the product 130 and accurately place the product 130 on the tray 120.

[0088] It should be noted that the synchronous movement of the camera 630 and the material picking component 610 on the horizontal plane means that the camera 630 and the material picking component 610 have the same displacement on the horizontal plane, that is, the relative positions of the camera 630 and the material picking component 610 on the horizontal plane remain unchanged.

[0089] In another embodiment, the transfer module 600 also includes a fill light 640, which moves synchronously with the pick-up component 610 on a horizontal plane (see below, the fill light 640 is mounted on the connector 625). The fill light 640 is used to emit illumination light toward the product 130 and the tray 120 so that the camera 630 can obtain a clearer image.

[0090] Reference Figure 5 and Figure 6In the improved embodiment described above, both the fourth and fifth directions are parallel to the horizontal plane, and the included angle between the fourth and fifth directions is greater than zero. The fifth driving assembly 620 includes a connecting base 625, a first driving member 621, and a second driving member 622. The material handling component 610 and the camera 630 are both mounted on the connecting base 625. The first driving member 621 drives the connecting base 625 to move along the fourth direction. The second driving member 622 drives the connecting base 625 to move along the fifth direction.

[0091] By mounting both the picking component 610 and the camera 630 on the connecting base 625, and by using the first driving component 621 and the second driving component 622 to drive the connecting base 625, the synchronous movement of the camera 630 and the picking component 610 on the horizontal plane can be accurately achieved.

[0092] Specifically, the angle between the fourth and fifth directions can be 45 degrees, 60 degrees, 75 degrees, 90 degrees, or other angles. Preferably, the angle between the fourth and fifth directions is 90 degrees, for example, the fourth direction is the left-right direction and the fifth direction is the front-back direction.

[0093] Specifically, the second drive unit 622 is installed at the output end of the first drive unit 621, and the connector 625 is installed at the output end of the second drive unit 622.

[0094] Specifically, the first driving component 621 can be one of the following: a cylinder, a hydraulic cylinder, a linear motor, a motor-driven gear and rack mechanism, a motor-driven crank and slider mechanism, a motor-driven lead screw and nut mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven sprocket and chain mechanism.

[0095] Specifically, the second driving component 622 can be one of the following: a cylinder, a hydraulic cylinder, a linear motor, a motor-driven gear and rack mechanism, a motor-driven crank and slider mechanism, a motor-driven lead screw and nut mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven sprocket and chain mechanism.

[0096] Reference Figure 5 and Figure 6 In the improved embodiment described above, the fifth drive assembly 620 further includes a third drive member 623 and a fourth drive member 624. The third drive member 623 is mounted on the connecting base 625 and is used to drive the picking member 610 to move in the vertical direction. The fourth drive member 624 is mounted on the connecting base 625 and the third drive member 623 is used to drive the picking member 610 to rotate about a vertical axis.

[0097] By providing the third drive component 623, the picking component 610 can move closer to or further away from the material tray 120 in the vertical direction. By providing the fourth drive component 624, the picking component 610 can adjust the angle of the product 130 around the vertical direction. By providing the third drive component 623 and the fourth drive component 624, the transfer module 600 has a higher degree of freedom and stronger mobility.

[0098] Specifically, the third driving component 623 can be one of the following: a cylinder, a hydraulic cylinder, a linear motor, a motor-driven gear and rack mechanism, a motor-driven crank-slider mechanism, a motor-driven lead screw and nut mechanism, a motor-driven synchronous pulley and synchronous belt mechanism, and a motor-driven sprocket and chain mechanism.

[0099] Specifically, the fourth drive component 624 can be an electric motor or a rotary cylinder.
