Description

Technical Field

[0001] The present invention relates to a laser printer, and more particularly to a fully automatic laser printer for chips applied in the field of laser printing technology. Background Technology

[0002] Laser printing uses a laser beam to quickly "project" digital graphics or documents onto a photosensitive surface. Electron discharge occurs at the location hit by the laser beam. High-energy-density lasers are used to locally irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thus leaving a permanent mark. It has advantages such as good imaging effect and fast printing speed.

[0003] Chinese patent CN202221232397.3 discloses a "Transfer Device for a Chip Laser Printer," which includes two parallel guide rails, a movable seat, a slide rail, a limiting device, a conveyor belt, rollers, and a drive device. By placing the movable seat near the guide rails and setting the limiting device on the movable seat, the frame products on the conveyor belt can be accurately positioned, avoiding the problem of exceeding the working range set by production line personnel and failing to accurately reach the designated position.

[0004] The aforementioned laser printer uses a conveyor belt to transport the workpiece to be printed. However, the workpiece is manually fed upwards, and the loading and unloading operations are repetitive, resulting in a large workload. Furthermore, the loaded and unloaded workpieces are not properly preserved, which affects the laser printing efficiency. Summary of the Invention

[0005] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the loading and unloading operations are repetitive, the workload is large, and the workpieces loaded and unloaded are not properly preserved, which affects the efficiency of laser printing.

[0006] To address the aforementioned problems, this invention provides a fully automatic laser printer for chips, comprising a printer body, a feeding track fixedly connected to the bottom of the printer body, an upper feeding cross rail and an lower feeding cross rail fixedly connected to the top of both ends of the feeding track, and a material handling robot fixedly connected to the movable ends of both the upper feeding cross rail and the lower feeding cross rail, a suction gripper fixedly connected to the bottom of the material handling robot, a material basket window fixedly connected to the bottom ends of both the upper feeding cross rail and the lower feeding cross rail, the suction gripper corresponding to the upper opening of the material basket window, suction nozzles distributed in a matrix on the surface of the suction gripper, and grippers slidably connected to the left and right ends of the suction gripper; a material box is placed inside the material basket window, a lifting pad is movably connected to the bottom of the material box, multiple material sheets are stacked on the top of the lifting pad, a lifting rail is fixedly connected to the bottom of the material basket window, a lifting column is fixedly connected to the movable end of the lifting rail, and the top of the lifting column contacts the lifting pad.

[0007] In the aforementioned fully automatic laser printer for chips, the material sheets from the top of the material box are picked up by the suction gripper on the material handling robot and placed in an orderly manner on the feeding track. At the same time, the material sheets in the lower layer of the material box are pushed out in sequence by the lifting pad, realizing the fully automatic loading and unloading operation of the printer, effectively improving the printing efficiency. After the material loading is completed, the material box is directly used for unloading, effectively improving the utilization efficiency of the material box.

[0008] As a further improvement of this application, a material sheet monitor is fixedly connected between the feeding cross rail and the printer body, and the sensing end of the material sheet monitor is vertically aligned with the feeding rail. The material sheet monitor is used to detect the conveying status of the feeding rail and the surface of the material sheet, which effectively improves the accuracy of laser printing.

[0009] As a further improvement of this application, the front and rear ends of the material box are movably connected to limit baffles, and the outer side of the limit baffles is movably connected to a rotating belt. The inner ring of the rotating belt is slidably connected to the surface of the limit baffles. The two ends of the lifting pad are fixedly connected to the two rotating belts respectively. The limit baffles restrict the left and right ends of the material sheet. The rotating belt is driven to rotate on the limit baffles by the lifting pads, which effectively improves the stability of the material sheet rising and falling.

[0010] As a further improvement of this application, the bottom end face of the lifting pad is fixedly connected with a clamping groove, the top of the lifting column is L-shaped and bent, and the top of the lifting column is inserted into the clamping groove. The rotating belt is vertically aligned with the lifting column. When the material box is placed into the material basket window, the clamping groove at the bottom of the lifting pad is inserted into the top of the lifting column, so that the lifting column can both lift the lifting pad upward and pull the lifting pad downward.

[0011] As another improvement of this application, the rotating belt is fixedly connected to the surface of the belt with parallel clamping bars, and the gap between two adjacent clamping bars corresponds to the edge of the material sheet being clamped. When the rotating belt rotates and rises to the top of the limiting baffle, the two adjacent clamping bars open to release the clamping and fixing of the material sheet. Conversely, when the rotating belt rotates and descends, the two clamping bars close to clamp and fix the material sheet, effectively improving the stability of the material sheet in the material box.

[0012] As a further improvement to this application, the diameter of the clamping bar is greater than the thickness of the claw tip. The clamping bar is made of rubber material. The rubber clamping bar has good elasticity, which effectively improves the clamping effect on the material sheet. At the same time, the clamping bar separates the stacked material sheets, which effectively prevents the material sheets from sticking together and makes it easier for the claw to pick up the material sheets.

[0013] As a further improvement to this application, the top and bottom of the limiting baffle are fixedly connected to a fixed shaft tube, and both ends of the fixed shaft tube are rotatably connected to a rotating wheel. The rotating wheel is connected to the rotating belt for transmission, thereby effectively improving the rotational capacity of the rotating belt.

[0014] As another improvement of this application, spring pins are inserted at both ends of the lifting pad, and a slot hole is opened in the middle of the fixed shaft tube. The spring pins are inserted into the slot hole, and the position of the lifting pad is limited by the insertion of the spring pins into the slot hole, which facilitates the switching between feeding and discharging of the material box.

[0015] As a further improvement to this application, a movable column is slidably connected inside the fixed shaft tube, and an extrusion block is fixedly connected to the outer surface of the movable column. The extrusion block extends through the slot hole, and the outer end of the extrusion block corresponds to the inclined surface of the spring pin. The position is switched by the extension and retraction of the extrusion block inside the fixed shaft tube, and the spring pin is then extruded by the extrusion block to release the insertion state between the spring pin and the slot hole.

[0016] As a further improvement to this application, a threaded shaft is threadedly connected to one end of the fixed shaft tube. The end of the threaded shaft near the slot hole is movably connected to the movable column, and the end of the threaded shaft away from the slot hole extends through the material box. By screwing the threaded shaft in and out, the movable column can move in and out of the fixed shaft tube.

[0017] In summary, during the loading and unloading process of the laser printer in this solution, the suction plate on the material handling robot picks up the sheet material from the top of the material box and places it orderly on the feeding track. The material boxes in the two material basket windows are fed alternately, effectively improving the loading efficiency. At the same time, the sheet material in the lower layer of the material box is pushed out by the lifting pad in sequence. After the subsequent material box is finished loading, it is directly used in the material basket window at the output end to put the printed sheet material back into the material box, realizing the fully automatic loading and unloading operation of the printer, effectively improving the utilization efficiency of the material box, and further improving the printing efficiency.

Detailed Implementation

[0031] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0032] First implementation method:

[0033] Figure 1-4The diagram shows a fully automatic laser printer for chips, comprising a printer body 1. A feeding track 2 is fixedly connected to the bottom of the printer body 1. An upper feeding cross rail 201 and an lower feeding cross rail 202 are fixedly connected to the top of both ends of the feeding track 2, respectively. A material handling robot 203 is fixedly connected to the movable ends of both the upper and lower feeding cross rails 201 and 202. A material sheet detector 101 is fixedly connected between the upper feeding cross rail 201 and the printer body 1, and the sensing end of the material sheet detector 101 is vertically aligned with the feeding track 2. The material sheet monitor 101 is used to detect the conveying status of the feeding track 2 and the surface of the material sheet 302, which effectively improves the accuracy of laser printing. The bottom of the material handling robot 203 is fixedly connected to the suction plate 204. The bottom ends of the loading cross rail 201 and the unloading cross rail 202 are both fixedly connected to the basket window 205. The suction plate 204 corresponds to the upper opening of the basket window 205. The surface of the suction plate 204 is matrix-distributed with suction nozzles 206. The left and right ends of the suction plate 204 are slidably connected to the grippers 207.

[0034] During laser printing, the material handling robot 203 on the loading cross rail 201 moves to the material basket window 205 and uses the suction nozzle 206 on the suction gripper 204 to pick up the material sheet 302. Then, the material sheet 302 is placed on the feeding track 2 and sent into the printer body 1. During the conveying process, the material sheet monitor 101 detects the conveying status of the feeding track 2 and the surface of the material sheet 302, which effectively improves the accuracy of laser printing. After printing, the material sheet 302 is returned to the material basket window 205 at the discharge end.

[0035] Figure 3-5 As shown, a material box 3 is placed inside the material basket window 205. A lifting pad 301 is movably connected to the bottom of the material box 3. Multiple material pieces 302 are stacked on the top of the lifting pad 301. A lifting rail 303 is fixedly connected to the bottom of the material basket window 205. A lifting column 304 is fixedly connected to the movable end of the lifting rail 303. The top of the lifting column 304 contacts the lifting pad 301.

[0036] Before laser printing, the material box 3 containing the sheet 302 is placed into the material basket window 205. The lifting column 304 on the lifting rail 303 applies an upward pushing force to the lifting pad 301, so that the sheet 302 stacked on top of the lifting pad 301 is pushed out of the material basket window 205 in sequence, which facilitates the feeding of the sheet 302. After the sheet 302 in the material box 3 is fed, the empty material box 3 is transferred to the material basket window 205 at the discharge end, so that the material box 3 can receive the printed sheet 302, which effectively improves the utilization efficiency of the material box 3.

[0037] Second implementation method:

[0038] Compared to the first embodiment, this embodiment mainly adds a rotating belt ring 401. The specific added structure is as follows, while the rest of the structure is the same as the first embodiment.

[0039] Figure 5-6 As shown, the front and rear ends of the material box 3 are movably connected to the limiting baffles 4, and the outer side of the limiting baffles 4 is movably connected to the rotating belt ring 401. The inner ring of the rotating belt ring 401 is slidably connected to the surface of the limiting baffles 4. The two ends of the lifting pad 301 are fixedly connected to the two rotating belt rings 401 respectively. The limiting baffles 4 restrict the left and right ends of the material piece 302. The rotating belt ring 401 is driven to rotate on the limiting baffles 4 by the lifting pad 301, which effectively improves the stability of the material piece 302 rising and falling. The bottom end of the lifting pad 301 is fixedly connected to the clamping plate groove 305. The top end of the lifting column 304 is L-shaped and bent, and the top end of the lifting column 304 is inserted into the clamping plate groove 305. The rotating belt ring 401 is vertically corresponding to the lifting column 304.

[0040] Compared to the first embodiment, in this embodiment, when the material box 3 is placed into the material basket window 205, the clamping groove 305 at the bottom of the lifting pad 301 is inserted into the top of the lifting column 304, so that the lifting column 304 can both lift the lifting pad 301 upward and pull the lifting pad 301 downward. The limiting baffle 4 restricts the two ends of the material piece 302, effectively improving the placement stability of the material piece 302. At the same time, the rotating belt ring 401 is placed between the material piece 302 and the limiting baffle 4, effectively preventing the edge wear of the material piece 302 and effectively improving the protection capability of the material piece 302.

[0041] Figure 6-7 As shown, the rotating belt 401 has parallel clamping bars 402 fixedly connected to its surface, and the gap between two adjacent clamping bars 402 corresponds to clamping the edge of the material piece 302. When the rotating belt 401 rotates and rises to the top of the limiting baffle 4, the two adjacent clamping bars 402 open, releasing the clamping and fixing of the material piece 302. Conversely, when the rotating belt 401 rotates and descends, the two clamping bars 402 close and clamp the material piece 302, effectively improving the stability of the material piece 302 in the material box 3. The diameter of the clamping bars 402 is larger than the thickness of the claw tip of the gripper 207. The clamping bars 402 are made of rubber material. The rubber clamping bars 402 have good elasticity, effectively improving the clamping effect of the material piece 302. At the same time, the clamping bars 402 separate the stacked material pieces 302, effectively preventing the material pieces 302 from sticking together, making it easier for the gripper 207 to pick up the material piece 302.

[0042] Compared to the first embodiment, this embodiment uses the clamping bar 402 on the rotating belt 401 to clamp and fix the edge of the material sheet 302, so as to achieve orderly stacking of the material sheet 302. At the same time, the clamping bar 402 separates the stacked material sheets 302, effectively preventing the material sheets 302 from sticking together. It also makes it convenient for the claw tip of the gripper 207 to insert into the bottom of the material sheet 302, so as to facilitate the orderly picking of the material sheet 302.

[0043] The third implementation method:

[0044] Compared to the second embodiment, this embodiment mainly adds a fixed shaft tube 5. The specific added structure is as follows, while the rest of the structure is the same as the first and second embodiments.

[0045] Figure 8-11 As shown, the top and bottom of the limiting baffle 4 are fixedly connected to a fixed shaft tube 5, and both ends of the fixed shaft tube 5 are rotatably connected to a rotating wheel 501. The rotating wheel 501 is connected to the rotating belt ring 401 for transmission. The rotating wheel 501 effectively improves the rotational capacity of the rotating belt ring 401. Both ends of the lifting pad 301 are inserted with spring pins 502. The middle part of the fixed shaft tube 5 is provided with a slot hole 503. The spring pins 502 are inserted into the slot hole 503. By inserting the spring pins 502 into the slot hole 503, the position of the lifting pad 301 is limited, which facilitates the switching between feeding and discharging of the material box 3.

[0046] In this embodiment, the rotating wheel 501 effectively improves the rotational capacity of the rotating belt ring 401. During the material discharge process of the material box 3, when the lifting pad 301 rises to the top of the material box 3, that is, after the material pieces 302 in the material box 3 are completely removed, the spring pins 502 at both ends of the lifting pad 301 are inserted into the slot holes 503 in the middle of the fixed shaft tube 5 to fix the position of the lifting pad 301, which facilitates the subsequent transfer of the empty material box 3 to the discharge end. Conversely, when the lifting pad 301 descends to the bottom of the material box 3, that is, after the material box 3 is filled with material pieces 302, the lifting pad 301 is locked, which effectively prevents accidental contact with the lifting pad 301 and causes the material pieces 302 to be accidentally pushed out of the material box 3.

[0047] Figure 9-11As shown, a movable column 504 is slidably connected inside the fixed shaft tube 5. An extrusion block 505 is fixedly connected to the outer surface of the movable column 504, and the extrusion block 505 extends through the slot hole 503. The outer end of the extrusion block 505 corresponds obliquely to the spring pin 502. The position is switched by the extension and retraction of the extrusion block 505 inside the fixed shaft tube 5. The spring pin 502 is then extruded by the extrusion block 505, releasing the insertion state of the spring pin 502 and the slot hole 503. A threaded shaft 506 is threadedly connected to one end of the fixed shaft tube 5. The end of the threaded shaft 506 near the slot hole 503 is movably connected to the movable column 504. The end of the threaded shaft 506 away from the slot hole 503 extends through the material box 3. The extension and retraction of the movable column 504 inside the fixed shaft tube 5 is realized by screwing in and out of the threaded shaft 506.

[0048] In this embodiment, when using the material box 3, the threaded shaft 506 is selectively screwed in and out according to the position of the material box 3, which drives the movable column 504 in the fixed shaft tube 5 to extend and retract. The spring pin 502 is squeezed out by the extrusion block 505, and conversely, the extrusion block 505 makes the slot hole 503 open, so that the spring pin 502 can be inserted into the slot hole 503, realizing the locking contact of the lifting pad 301, which facilitates the free conversion of the material box 3's usage state and effectively improves the usage efficiency of the material box 3.

[0049] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
