DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, a feeding device for laser engraving of a metal mirror surface of a notebook shell described in the present invention comprises a conveying table 1, a laser engraving machine 2 is installed at the end of the conveying table 1, a conveying structure 3 is provided on the inner side of the conveying table 1, a positioning structure 4 is connected to the conveying structure 3, a delivery structure 5 is provided on the top side of the conveying table 1, a driving structure 8 is connected between the delivery structure 5 and the positioning structure 4, a supporting structure 7 is provided on the side of the delivery structure 5, and a cleaning structure 6 is provided on the bottom side of the conveying table 1.

[0036] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig.10 and Fig.11 As shown, the conveying structure 3 includes a motor 301, and the motor 301 is installed on the side of the conveying platform 1. The end of the motor 301 is fixedly connected to a driving shaft 308 through a coupling, and the end of the driving shaft 308 is fixedly connected to a second pulley 307. The two sides of the conveying platform 1 are respectively rotatably connected to the first pulley 305, and a toothed belt 306 is sleeved between the first pulley 305 and the second pulley 307. The two ends of the conveying platform 1 are respectively rotatably connected to a roller 303 , a conveyor belt 302 is sleeved on the two roller shafts 303, a transmission gear 304 is fixedly connected to the end of the roller shaft 303, the side of the toothed belt 306 is meshed with the transmission gear 304, the side of the toothed belt 306 is provided with a toothed structure, and the toothed structure on the side of the toothed belt 306 covers a half of the total length of the toothed belt 306, and a support plate 309 is fixedly connected to the middle of the conveyor platform 1, and the inner side of the conveyor belt 302 is slidably connected to the support plate 309;

[0037] In order to facilitate the addition of notebook shells, the motor 301 on the side of the conveyor platform 1 is electrically connected to the external power supply. When the motor 301 is started, the motor 301 will drive the two second pulleys 307 to start rotating through the drive shaft 308, thereby causing the toothed belt 306 sleeved on the second pulley 307 and the first pulley 305 to start rotating, and the toothed belt 306 is meshed with the transmission gear 304 at the end. At this time, the conveyor belt 302 in the middle of the conveyor platform 1 starts to rotate. Since the toothed structure on the side of the toothed belt 306 only covers half of the toothed belt 306, when the toothed part is separated from the transmission gear 304, the conveyor belt 302 stops rotating, thereby achieving an intermittent conveying effect of the conveyor belt 302. At this time, if the notebook shell is placed on the conveyor belt 302, the feeding of the notebook shell can be completed while the laser engraving operation is performed through the laser engraving machine 2, thereby improving production efficiency.

[0038] Specifically, Figure 3 , Figure 4 , Figure 8 As shown, the positioning structure 4 includes a push rod 401, and a plurality of push rods 401 are equidistantly arranged on the conveyor belt 302 in sequence, and the two ends of the push rod 401 are fixedly connected to the two sides of the conveyor belt 302 respectively, and a telescopic slide rod 403 is slidably connected to the two sides of the push rod 401 respectively, and a first spring 406 is fixedly connected between the telescopic slide rods 403 arranged on both sides, and the side of the telescopic slide rod 403 is rotatably connected to a connecting rod 404, and the end of the connecting rod 404 is slidably connected to a gathering rod 405, and the gathering rod 405 is rotatably connected to the push rod 401, and the angle between the connecting rod 404 and the telescopic slide rod 403 is an acute angle, and the two sides of the conveyor platform 1 are symmetrically provided with a resistance groove 402, and the middle part of the resistance groove 402 is a wave-shaped structure, and the depth of the resistance groove 402 on one side close to the laser engraving machine 2 is greater than that on the other side, and the end of the telescopic slide rod 403 is slidably connected to the conveyor platform 1 through the resistance groove 402 opened on the same side;

[0039] In order to ensure that the notebook shell on the conveyor belt 302 maintains the accuracy of the position during the conveying process, that is, when the conveyor belt 302 stops rotating, the notebook shell can accurately stop directly below the laser engraving machine 2, a plurality of push rods 401 are provided on the conveyor belt 302, and the telescopic slide rods 403 at both ends of the push rods 401 are slidably connected to the conveying platform 1 through the abutment grooves 402. During the conveying process of the notebook shell, the telescopic slide rod 403 will pass through the wavy structure area of ​​the abutment groove 402, at which time the telescopic slide rod 403 will slide back and forth, and then the gathering rod 404 will be connected to the notebook shell through the connecting rod 404. 405 is repeatedly pulled, so that the gathering rod 405 reciprocates at a certain angle. During this process, if a notebook shell is placed on the side of the pushing rod 401, the notebook shell can be moved to the center position of the conveyor belt 302 through the gathering action of the gathering rod 405. When the telescopic slide rod 403 slides to the horizontal part of the abutment groove 402, the telescopic slide rod 403 is fully stretched, so that the connecting rod 404 pulls the gathering rod 405 to maintain a vertical state with the pushing rod 401. At this time, when the notebook shell moves to the bottom of the laser engraving machine 2, the accuracy of the position can be guaranteed.

[0040] Specifically, Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the delivery structure 5 includes a storage slot 501, the delivery platform 1 is provided with the storage slot 501, the storage slot 501 is arranged on the top side of the push rod 401, the side of the storage slot 501 is threadedly connected with an adjusting screw 502, the inner side of the storage slot 501 is slidably connected with a lifting block 503, the lifting block 503 is threadedly connected with the adjusting screw 502, the end of the lifting block 503 is fixedly connected with a bearing plate 504, the bearing plate 504 is slidably connected with the storage slot 501, and the bearing plate 504 is provided with a delivery slot 505;

[0041] A storage slot 501 is provided on the top side of the conveyor table 1. The operator can stack the notebook shells to be processed into the storage slot 501. The supporting plate 504 on the bottom side of the storage slot 501 is used to support the notebook shells. At the same time, the user can make fine adjustments according to the thickness of the notebook shells by rotating the adjusting screw 502 on the top side of the storage slot 501 so that the adjusting screw 502 drives the lifting block 503 to change the height, thereby adjusting the distance between the supporting plate 504 and the bottom of the storage slot 501 to ensure that the notebook shells can slide out from the side of the supporting plate 504, and the notebook shells that slide out can freely fall onto the conveyor belt 302 below.

[0042] Specifically, Figure 7 , Figure 8 , Fig. 9As shown, the driving structure 8 includes a pushing rod 801, the side of the storage slot 501 is slidably connected with the pushing rod 801, a fifth spring 805 is fixedly connected between the pushing rod 801 and the storage slot 501, the end of the pushing rod 801 is slidably connected with the carrier plate 504 through the delivery slot 505, and a resistance block 804 is fixedly connected to the push rod 401, and the side of the resistance block 804 is horizontally aligned with the bottom side of the pushing rod 801. A positioning block 802 is slidably connected to the inner side of the end of the pushing rod 801. Both ends of the positioning block 802 are hemispherical structures. The top of the positioning block 802 is slidably connected to the storage slot 501. The bottom end of the positioning block 802 is in conflict with the conflict block 804. An avoidance groove 803 is provided on the bottom side of the storage slot 501. A sorting plate 806 is rotatably connected to the side of the storage slot 501. The side of the sorting plate 806 is in conflict with the conveyor belt 302.

[0043] Since the notebook shell in the storage slot 501 can slide out from the side of the carrying plate 504, when the conveyor belt 302 starts to rotate, the pushing rod 401 located on the surface of the conveyor belt 302 will pass through the bottom side of the storage slot 501 in turn. During this process, the resistance block 804 set on the top side of the pushing rod 401 will conflict with the end of the positioning block 802 at the end of the pushing rod 801, thereby pushing the pushing rod 801 to slide in the moving direction of the conveyor belt 302 at the same time, until the positioning block 802 slides to the avoidance groove 803 position, the pushing of the resistance block 804 will cause the positioning block 802 to slide into the avoidance groove 803, at this time the support function of the resistance block 804 is lost, and the pushing rod 80 1 is pushed by the fifth spring 805 to restore the position. During this process, as the pushing rod 801 slides, the end of the pushing rod 801 slides into the delivery slot 505 provided on the carrier plate 504, thereby pushing the bottommost notebook shell on the carrier plate 504 toward the side of the carrier plate 504, and the pushed notebook shell falls onto the conveyor belt 302. During this process, the support of the support plate 309 can ensure that the pushing rod 401 always maintains a horizontal state, and then the blocking plate 705 blocks the falling notebook shell, and finally the notebook shell moves to conflict with the pushing rod 401, thereby realizing the automatic unloading operation of the notebook.

[0044] Specifically, Figure 5 , Figure 6As shown, the support structure 7 includes a release rod 701, a release rod 701 is slidably connected to the side of the storage slot 501, a third spring 702 is fixedly connected between the release rod 701 and the storage slot 501, the end of the release rod 701 is an inclined structure, a side plate 703 is slidably connected to the bottom side of the storage slot 501, a fourth spring 706 is fixedly connected between the side plate 703 and the storage slot 501, a blocking plate 705 is fixedly connected to the end of the side plate 703, a slot 704 is provided in the middle of the side plate 703, and the end of the release rod 701 is engaged with the side plate 703 through the slot 704;

[0045] Since the notebook shell can slide out from the side of the supporting plate 504, in order to prevent the notebook shell from sliding out during the placement process, the user can push in the side panel 703 on the side of the storage slot 501 so that the blocking plate 705 at the end of the side panel 703 is located on one side of the supporting plate 504, thereby providing support for the notebook shell. After the placement is completed, the user only needs to pull the release rod 701 to release the engagement state between the end of the release rod 701 and the side panel 703. At this time, the blocking plate 705 slides out, and the side of the supporting plate 504 allows the notebook shell to pass through.

[0046] Specifically, Figure 2 , Figure 7 , Fig.10 , Fig.11 As shown, the cleaning structure 6 includes a third pulley 605, the end of the driving shaft 308 is fixedly connected with the third pulley 605, the bottom side of the conveying platform 1 is rotatably connected with a cleaning rod 601, the side of the cleaning rod 601 is fixedly connected with a brush 602, the end of the cleaning rod 601 is provided with a fourth pulley 607, a transmission belt 606 is sleeved between the third pulley 605 and the fourth pulley 607, the end of the cleaning rod 601 is fixedly connected with a second spring 603, the end of the second spring 603 is fixedly connected with a rotating block 604, the rotating block 604 is rotatably connected to the conveying platform 1, the other end of the cleaning rod 601 is a prismatic structure, the end of the cleaning rod 601 is slidably connected with the fourth pulley 607, a side protrusion 608 is fixedly connected to the cleaning rod 601, the side of the side protrusion 608 is provided with a plurality of hemispherical protrusions, and a groove 609 is provided on the inner side of the conveying platform 1;

[0047] A cleaning rod 601 is provided on the bottom side of the conveyor platform 1. The cleaning rod 601 is driven by the driving shaft 308 to rotate through the transmission effect of the third pulley 605, the fourth pulley 607 and the transmission belt 606, so that the surface of the conveyor belt 302 is cleaned by the brush 602 on the cleaning rod 601 to prevent dust from affecting the calibration of the position of the notebook case. At the same time, during the rotation of the cleaning rod 601, the side protrusion 608 at one end of the cleaning rod 601 will repeatedly conflict with the groove 609, and cooperate with the second spring 603 set at the other end, thereby pushing the cleaning rod 601 to shake left and right, thereby improving the cleaning effect on the surface of the conveyor belt 302.

[0048] When the present invention is in use, first, in order to facilitate the addition of the notebook shell, the motor 301 on the side of the conveyor platform 1 is electrically connected to the external power supply. When the motor 301 is started, the motor 301 will drive the two second pulleys 307 to start rotating through the drive shaft 308, thereby causing the toothed belt 306 sleeved on the second pulley 307 and the first pulley 305 to start rotating, and the toothed belt 306 is meshed with the transmission gear 304 at the end. At this time, the conveyor belt 302 in the middle of the conveyor platform 1 starts to rotate. Since the toothed structure on the side of the toothed belt 306 only covers half of the toothed belt 306, when the toothed part is separated from the transmission gear 304, the conveyor belt 302 stops rotating, thereby achieving an intermittent conveying effect of the conveyor belt 302. At this time, if the notebook shell is placed on the conveyor belt 302, the feeding of the notebook shell can be completed while the laser engraving operation is performed through the laser engraving machine 2, thereby improving the production efficiency. In order to ensure that the notebook shell on the conveyor belt 302 maintains the accuracy of the position during the conveying process, that is, when the conveyor belt 302 stops rotating, the notebook shell can accurately stop directly under the laser engraving machine 2, a plurality of push rods 401 are provided on the conveyor belt 302, and the telescopic slide rods 403 at both ends of the push rod 401 are slidably connected to the conveying platform 1 through the abutment groove 402. In the process of conveying the notebook shell, the telescopic slide rod 403 will pass through the wavy structure area of ​​the abutment groove 402. At this time, the telescopic slide rod 403 will slide back and forth, and then through the connecting rod 40 4. The gathering rod 405 is repeatedly pulled to make the gathering rod 405 reciprocate at a certain angle. During this process, if a notebook shell is placed on the side of the push rod 401, the notebook shell can be moved to the center of the conveyor belt 302 through the gathering action of the gathering rod 405. When the telescopic slide rod 403 slides to the horizontal part of the abutment groove 402, the telescopic slide rod 403 is fully stretched, so that the connecting rod 404 pulls the gathering rod 405 to maintain a vertical state with the push rod 401. At this time, when the notebook shell moves to the bottom of the laser engraving machine 2, the accuracy of the position can be guaranteed. A storage slot 501 is provided on the top side of the conveyor table 1. The operator can stack the notebook shells to be processed into the storage slot 501. The storage slot 501 The carrying plate 504 on the bottom side of 01 is used to carry the notebook shell. At the same time, the user can make fine adjustments according to the thickness of the notebook shell. By rotating the adjusting screw 502 on the top side of the storage slot 501, the adjusting screw 502 drives the lifting block 503 to change the height, thereby adjusting the distance between the carrying plate 504 and the bottom of the storage slot 501 to ensure that the notebook shell can slide out from the side of the carrying plate 504. The notebook shell that slides out can fall freely onto the conveyor belt 302 below. Since the notebook shell in the storage slot 501 can slide out from the side of the carrying plate 504, when the conveyor belt 302 starts to rotate, the pushing rod 401 on the surface of the conveyor belt 302 will pass through the bottom side of the storage slot 501 in turn. During this process,The abutment block 804 provided on the top side of the push rod 401 will abut against the end of the positioning block 802 at the end of the pushing rod 801, thereby pushing the pushing rod 801 to slide in the moving direction of the conveyor belt 302 at the same time, until the positioning block 802 slides to the position of the avoidance groove 803, and the pushing of the abutment block 804 will cause the positioning block 802 to slide into the avoidance groove 803. At this time, the supporting effect of the abutment block 804 is lost, and the pushing rod 801 is pushed by the fifth spring 805 to restore its position. In this process, as the pushing rod 801 slides, the end of the pushing rod 801 slides into the supporting plate 5 04, thereby pushing the bottommost notebook shell on the carrier plate 504 toward the side of the carrier plate 504, and the pushed notebook shell falls onto the conveyor belt 302. During this process, the support of the support plate 309 can ensure that the push rod 401 always remains in a horizontal state, and then the blocking plate 705 blocks the falling notebook shell, and finally the notebook shell moves to conflict with the push rod 401, thereby realizing the automatic unloading operation of the notebook. Since the notebook shell can slide out from the side of the carrier plate 504 In order to prevent the laptop shell from sliding out during the placement process, the user can push the side plate 703 on the side of the storage slot 501 in, so that the blocking plate 705 at the end of the side plate 703 is located on one side of the carrying plate 504, thereby providing support for the laptop shell. After the placement is completed, the user only needs to pull the release rod 701 to release the engagement between the end of the release rod 701 and the side plate 703. At this time, the blocking plate 705 slides out, and the side of the carrying plate 504 allows the laptop shell to pass through. A cleaning rod 601 is provided on the bottom side of the conveying platform 1. The cleaning rod 601 passes through The third pulley 605, the fourth pulley 607 and the transmission belt 606 are driven by the driving shaft 308 to rotate, so that the surface of the conveyor belt 302 is cleaned by the brush 602 on the cleaning rod 601 to prevent dust from affecting the calibration of the notebook shell position.
