Description

Technical Field

[0001] This invention relates to the field of notebook computer casing conveying technology, and in particular to a feeding device for notebook computer processing. Background Technology

[0002] With the rapid development of the electronics and information industry, laptops have become indispensable tools in people's work and life. During the manufacturing process of laptops, in order to achieve functions such as product traceability, brand identification, and parameter descriptions, it is usually necessary to perform marking processing on specific locations on the laptop casing (such as the A-side top cover and D-side bottom cover). Currently, the industry widely adopts laser engraving technology to replace traditional screen printing or labeling processes. Laser engraving has significant advantages such as high processing precision, durable and clear markings, and no consumables, making it environmentally friendly.

[0003] In existing notebook casing conveying processes, such as Chinese patent CN119347181A, a feeding device for laser engraving of notebook casings is disclosed, including a bottom support base and a feeding tray. The feeding tray is closely attached to the upper surface of the bottom support base. A servo motor is fixed in the middle of the bottom support base. An electric push rod is vertically fixed at the front end of the inner side of the bottom support base. A feeding plate is fixed to the outer side of the upper surface of the feeding tray. A lifting plate is embedded in the middle of the feeding plate. An anti-slip plate is fixed to the top of the lifting plate. An outer plate is fixed to the upper surface of the feeding tray. An adjusting bolt is embedded inside the outer plate. One end of the adjusting bolt is connected to a connecting plate. Rotating rollers are rotatably connected to the upper and lower ends of the connecting plate near the middle of the feeding plate. A limit band is nested on the outer side of the rotating rollers.

[0004] The aforementioned existing technologies primarily rely on limiting the movement of the laptop casing during laser engraving to prevent it from shifting. However, these technologies fail to consider the rapid product iteration of laptops and the fact that the same mold often yields models of different sizes or configurations, resulting in diverse casing dimensions. Existing technologies typically use fixed-width guide rails or simple mechanical stops for positioning, which are difficult to adapt to casings of different sizes. When switching production models, manual shutdowns are often required to adjust equipment parameters or mechanical limits, leading to long changeover times, low production efficiency, and difficulty in ensuring consistency in laser engraving positions across different batches.

[0005] Therefore, there is still room for improvement in the aforementioned existing technologies. Summary of the Invention

This achieves a continuous operation mode of simultaneous transport and positioning, avoiding production capacity losses caused by downtime for adjusting the positioning mechanism in traditional processes. Addressing the issue of varying notebook casing sizes, this application innovatively constructs a mechanical size recognition and feedback system based on multi-level swing and limit mechanisms. This system automatically triggers different levels of avoidance and positioning actions according to the actual width of the casing, seamlessly switching between processing flows for different product specifications without manual intervention. Simultaneously, the feeding module receives centering status feedback through a linkage module, automatically adjusting the suction distance of the pick-up suction cup and the airflow channel size of the vent valve.

[0035] The following is in conjunction with the appendix Figures 1-14 This application will be described in further detail.

[0036] This application discloses a feeding device for notebook computer processing. By dynamically centering different sized casings and adjusting the gripping state of the feeding module, it achieves adaptive and precise feeding of casings of different specifications.

[0037] Reference Figure 1 As shown, a feeding device for notebook computer processing includes a feeding module 1, which includes a first feeding belt 11 and a second feeding belt 12; a worktable 2, located between the first feeding belt 11 and the second feeding belt 12, on which a laser engraving module 3 is provided; a mounting bracket 4, located at the end of the first feeding belt 11, on which lateral centering modules 5 are symmetrically provided; the lateral centering modules 5 are used to continuously abut against the side of the notebook casing, pushing it toward the centerline of the first feeding belt 11 to achieve dynamic centering of notebook casings of different sizes; a suspension 6, mounted on the worktable 2, on which a feeding module 7 and an unloading module 8 are sequentially provided; the feeding module 7 adaptively adjusts the adsorption range and adsorption force to adapt to notebook casings of different sizes; and a linkage module 9, located on the mounting bracket 4, serving as the docking reference for the feeding module 7, and adjusting the feeding module 7 to a matching gripping state based on the centering state feedback of the lateral centering module 5.

[0038] In actual operation, the laptop casing is conveyed via the first feeding belt 11. The mounting bracket 4 pre-guides the casing arriving at the end of the first feeding belt 11. Then, the lateral centering module 5 adaptively pushes and adjusts the casing's position according to its size. The lateral centering module 5 also provides status feedback to the linkage module 9 to clarify the size and specifications of the adjusted casing. After that, the feeding module 7 moves to pick up the casing, and the linkage module 9 provides feedback on the size of the casing to be picked up to the feeding module 7. The feeding module 7 adjusts the suction range and adsorption intensity to smoothly pick up the precisely positioned casing. After that, the casing is transferred to the laser marking module 3 for laser marking and other operations. After processing, the unloading module 8 transfers the casing to the second feeding belt 12 for continued conveying. This application adjusts and restricts the casing's position while it is being conveyed, reducing the alignment time required for picking up and placing the casing, and flexibly adapting to casings of different sizes, thereby improving production efficiency.

[0039] Reference Figure 2 As shown, the mounting bracket 4 consists of a front layer frame 41, a rear layer frame 42, and an end frame 43. The front layer frame 41 and the rear layer frame 42 are respectively installed on the front and rear sides of the first feeding belt 11. The front layer frame 41 and the rear layer frame 42 form a conveying channel 44. The left side of the conveying channel 44 is a triangular open section that is inclined, and the right side is a straight conveying section. The working surface of the triangular open section is provided with a flexible anti-collision layer. The end frame 43 is installed on the end side of the first feeding belt 11 and is fixedly connected to the front layer frame 41.

[0040] In actual operation, when the laptop casing reaches the end of the first feeding belt 11, it enters the triangular open section of the conveyor chute 44. At this time, if the casing is offset in the front-to-back direction relative to the first feeding belt 11, the casing will contact and be squeezed with the inclined surface of the triangular open section, so that the casing can smoothly enter the straight conveyor section.

[0041] Reference Figure 3 As shown, the lateral centering module 5 includes a first swing member 51, which is rotatably disposed inside the front shelf 41, and a torque spring connects the first swing member 51 to the front shelf 41; a second swing member 52, which is rotatably disposed inside the front shelf 41, and a torque spring connects the second swing member 52 to the front shelf 41, the second swing member 52 being located to the right of the first swing member 51, and the rotation angle of the second swing member 52 being greater than that of the first swing member 51; and a third swing member 53, which is rotatably disposed inside the front shelf 41, and a torque spring connects the third swing member 53 to the front shelf 41, the third swing member 53 being located to the right of the second swing member 52, and the rotation angle of the third swing member 53 being greater than that of the second swing member 52. Therefore, the distance between the symmetrically arranged first swing members 51 is greater than the distance between the second swing members 52, which is greater than the distance between the third swing members 53, thus adapting to different sized housings; the first swing member 51, the second swing member 52, the third swing member 53 ...1, the third swing member 52, the third swing member 53, the third swing The second swing member 52 and the third swing member 53 have the same structure, and both of their working surfaces are provided with a flexible anti-collision layer. The front shelf 41 is provided with a first limiting mechanism 54, a second limiting mechanism 55, and a third limiting mechanism 56, which correspond to the positions of the first swing member 51, the second swing member 52, and the third swing member 53, respectively. The first limiting mechanism 54 is fixedly connected to the front shelf 41, and the second limiting mechanism 55 and the third limiting mechanism 56 are slidably connected to the front shelf 41. A traction drive 57 is provided in the front shelf 41, and a traction plate 58 is installed at the output end of the traction drive 57. The traction plate 58 is slidably disposed inside the front shelf 41. The second limiting mechanism 55 and the third limiting mechanism 56 are connected to the traction plate 58 through a disconnecting component 59 and a fixing component 60, respectively. The second limiting mechanism 55 and the third limiting mechanism 56 are connected to the second swing member 52 and the third swing member 53 through a traction rope 61, respectively.

[0042] In actual operation, since housings come in various sizes, we assume three different housing specifications: housing A, housing B, and housing C, where housing A is larger than housing B, which is larger than housing C.

[0043] When housing A is being conveyed, housing A comes into contact with the first swing member 51. The initial distance between the first swing members 51 is less than the width of housing A, so the housing A and the first swing member 51 are squeezed together. The first swing member 51 is completely pushed away. The first swing member 51, which is completely pushed away, triggers the traction drive 57 through the first limiting mechanism 54. The traction drive 57 drives the traction plate 58 to pull back. The second limiting mechanism 55 and the third limiting mechanism 56 are pulled apart and completely hidden into the front shelf 41. Therefore, it will not hinder the subsequent movement of housing A.

[0044] When housing B is being transported, the initial distance between the first swing members 51 is greater than the width of housing B, so housing B passes smoothly (even if housing B deviates and collides with the first swing member 51, the first swing member 51 will gently guide housing B to the center trajectory. The width of housing B is small and cannot completely push the first swing member 51 away, so the traction drive 57 will not be triggered). However, the initial distance between the second swing member 52 is less than the width of housing B. Therefore, housing B and the second swing member 52 are squeezed together, and the second swing member 52 is completely pushed away. The completely pushed-away second swing member 52 triggers the traction drive 57 through the second limiting mechanism 55. The traction drive 57 drives the traction plate 58 to pull back. At the same time, after the second limiting mechanism 55 is triggered, the disconnection component 59 is unlocked, and the connection between the second limiting mechanism 55 and the traction plate 58 is broken. Therefore, only the third limiting mechanism 56 is pulled apart along with the traction plate 58 and completely hidden in the front shelf 41, no longer hindering the subsequent movement of housing B.

[0045] When the housing C is being conveyed, its relatively small size allows it to pass smoothly through the first swing member 51 and the second swing member 52.

[0046] The initial distance between the third swing members 53 is less than the width of the housing C. Therefore, the housing C and the third swing members 53 are squeezed together, and the third swing members 53 are completely pushed apart, thus allowing them to pass smoothly.

[0047] Reference Figure 4 , Figure 5 , Figure 14 As shown, the second limiting mechanism 55 includes a movable seat 551, which is slidably disposed in the front shelf 41, and a hollow groove 5511 is provided inside the movable seat 551; a top contact 552, which is slidably disposed in the hollow groove 5511, and a first spring is connected between the top contact 552 and the movable seat 551, the first spring serving as a reset function; and a sensor switch 553, which is disposed in the hollow groove 5511, the sensor switch 553 and the top contact 552 being in a pressing fit, and the sensor switch 553 being electrically connected to the traction drive 57.

[0048] In actual operation, the housing presses the second swing member 52, the second swing member 52 presses the top contact 552, and the top contact 552 presses the inductive switch 553, thereby triggering it. The traction drive 57 is started only when both symmetrically arranged inductive switches 553 are triggered.

[0049] Reference Figure 4 As shown, the first limiting mechanism 54 and the second limiting mechanism 55 have the same internal structure but different installation methods. The third limiting mechanism 56 has the same basic structure as the second limiting mechanism 55. The third limiting mechanism 56 does not include the inductive switch 553.

[0050] In actual operation, the position of the first limiting mechanism 54 remains unchanged because the distance between the first swinging members 51 is large enough that there is no need to avoid it. Correspondingly, when the third limiting mechanism 56 is triggered, it means that the size of the housing is small at this time, which is the smallest size that this application can adapt to. Therefore, at this time, the third limiting mechanism 56 does not need to cooperate with the traction drive 57 to avoid it.

[0051] Reference Figure 5 As shown, the disconnection assembly 59 includes a fixing pin 591, which is installed on the side of the movable seat 551, and the interior of the fixing pin 591 is a hollow structure; a fixing clip 592, which is installed on the side of the traction plate 58, and the fixing clip 592 is sleeved on the outer periphery of the fixing pin 591; a movable clip 593, which is symmetrically slidably disposed inside the fixing pin 591, and a second spring is connected between the movable clip 593 and the fixing pin 591, the second spring playing a reset role, the movable clip 593 is an elastic and telescopic structure, and the front end face of the movable clip 593 is provided with a chamfer; a mating part 594, the rear end of which is fixedly connected to the top contact 552, and a top support 595 is installed at the front end of the mating part 594, the top support 595 is located between the movable clips 593, and in the initial state, the top support 595 squeezes the movable clip 593 outward, at which time the second spring is compressed, and the rear end of the top support 595 is provided with a chamfer.

[0052] Reference Figure 4 As shown, the basic structure of the fixed connection component 60 and the disconnection component 59 is the same, but the fixed connection component 60 does not include the mating part 594.

[0053] In actual operation, the top contact 552 is pressed and moved, the mating part 594 moves with the top contact 552, and the top support 595 moves with the mating part 594, thus disengaging from the middle position of the movable locking part 593. Under the reset action of the second spring, the movable locking part 593 retracts into the interior of the fixed pin 591, thereby unlocking the fixed locking part 592 and the fixed pin 591, that is, unlocking the moving seat 551 and the traction plate 58. The fixed connection assembly 60 remains connected and does not need to be unlocked. During subsequent reset, the fixed locking part 592 presses the movable locking part 593, and the movable locking part 593 is compressed and extends itself, so the fixed locking part 592 successfully passes over the movable locking part 593 to reset.

[0054] Reference Figure 3 , Figure 7 , Figure 8 As shown, the linkage module 9 includes a positioning pin 91, which is rotatably mounted on the end frame 43. The positioning pin 91 corresponds to the positioning pin hole 721. A first adjusting pin 92 and a second adjusting pin 93 are evenly installed on the outer periphery of the positioning pin 91. The heights of the first adjusting pin 92 and the second adjusting pin 93 are different, which serve as a bridge to cooperate with the feeding module 7. A positioning stop 94 is installed on the left end of the end frame 43. An adjusting gear 95 is installed on the outer periphery of the positioning pin 91. An adjusting rack 96 is slidably mounted inside the end frame 43. A fourth spring connects the adjusting rack 96 and the end frame 43. The fourth spring plays a reset role. The adjusting rack 96 meshes with the adjusting gear 95. A feedback mechanism 97 is installed in the front layer frame 41.

[0055] Reference Figure 6 , Figure 8 , Figure 9 As shown, the feedback mechanism 97 includes a movable block 971, which is slidably disposed in the front shelf 41. A fifth spring 972 is connected between the movable block 971 and the front shelf 41, and the fifth spring 972 always exerts a leftward pushing force on the movable block 971. A connecting rope 973 is connected at one end to the movable block 971, and at the other end is connected to the adjusting rack 96 after passing through a fixed pulley 974. The fixed pulley 974 is rotatably disposed in the end shelf 43 and serves to change the direction of the force. A limit stop 975 is also included. It is installed on the moving block 971, and the left end face of the first limiting block 975 is chamfered; the second limiting block 976 is installed on the traction plate 58, and the second limiting block 976 has a mating groove 977. The left end of the first limiting block 975 is located in the mating groove 977, and the second limiting block 976 temporarily limits the first limiting block 975; the limiting rod 978 is installed on the moving block 971, and the bottom of the moving seat 551 has a limiting groove 979. The limiting rod 978 and the limiting groove 979 are in contact fit.

[0056] In actual operation, in the initial state, limit block 1 975 and limit block 2 976 cooperate to limit the movement block 971. Limit rod 978 and limit groove 979 also cooperate to limit the movement block 971. When the traction plate 58 moves, limit block 2 976 moves with the traction plate 58, separating from limit block 1 975. Simultaneously, the third limiting mechanism 56 and the second limiting mechanism 55 move with the traction plate 58, separating the limit groove 979 from the limit rod 978, preventing the movement block 971 from moving. Once again limited, under the action of the fifth spring 972, the moving block 971 is pushed out. The moving block 971 moves by pulling the adjusting rack 96 through the connecting rope 973 and the fixed pulley 974. Under the meshing action, the adjusting gear 95 rotates, thereby causing the positioning pin 91 to rotate. The positions of the first adjusting pin 92 and the second adjusting pin 93 change accordingly. When resetting, the second limiting block 976 moves and resets with the traction plate 58. At this time, the mating groove 977 presses the inclined chamfer of the first limiting block 975 to reset it.

[0057] During operation, there are several scenarios: both the third limiting mechanism 56 and the second limiting mechanism 55 move with the traction plate 58; only the third limiting mechanism 56 moves with the traction plate 58; and neither the third limiting mechanism 56 nor the second limiting mechanism 55 moves.

[0058] If both the third limiting mechanism 56 and the second limiting mechanism 55 move with the traction plate 58 (i.e., the case where the housing A is conveying), then the limiting rod 978 is not restricted by the limiting groove 979 at all, the moving block 971 is pushed out to the maximum, at which time the positioning pin 91 rotates to the maximum angle, and the first adjusting pin 92 rotates to the position that cooperates with the feeding module 7.

[0059] If only the third limiting mechanism 56 moves with the traction plate 58 (i.e., the case where the housing B is conveying), then the second limiting mechanism 55 remains in its original position, and the limiting groove 979 in the second limiting mechanism 55 still limits the limiting rod 978. The moving block 971 is pushed out but does not reach the maximum position. At this time, the second adjusting pin 93 rotates to the position that cooperates with the feeding module 7.

[0060] If neither the third limiting mechanism 56 nor the second limiting mechanism 55 moves (i.e., when the housing C is being transported), then there is no change.

[0061] Reference Figures 10-13As shown, the feeding module 7 includes a drive slider assembly 71, which is mounted on the suspension 6. The drive slider assembly 71 is a prior art drive component; a mounting shell 72, which is mounted on the output end of the drive slider assembly 71. The right end of the mounting shell 72 has a positioning pin hole 721, and the lower surface of the mounting shell 72 has evenly distributed sliding grooves 722; a part-picking suction cup 73, which is slidably disposed in the sliding groove 722, and a third spring connects the part-picking suction cup 73 and the sliding groove 722; and a floating plate 74, which is slidably disposed in the mounting shell 72. A trigger plate is mounted on the right side of the floating plate 74. 75; a first rack 76, which is installed at the lower end of the floating plate 74; a first gear 77, which is rotatably disposed in the mounting housing 72, and the first gear 77 meshes with the first rack 76; a second rack 78, which is installed on the side wall of the retrieval suction cup 73, and the second rack 78 meshes with the first gear 77; a third rack 79, which is installed on the bottom surface of the mounting housing 72; a vent valve 80, which is disposed inside the retrieval suction cup 73, the vent valve 80 is a prior art valve, and a second gear 81 is installed on the outer periphery of the vent valve 80 through an auxiliary component, and the second gear 81 meshes with the third rack 79.

[0062] In actual operation, the drive slider assembly 71 drives the mounting shell 72 to the picking position. The drive slider assembly 71 drives the mounting shell 72 to descend. The positioning pin hole 721 and the positioning pin 91 are aligned for positioning. If the housing C is being transported, the position of the picking suction cup 73 does not need to be adjusted (the picking suction cup 73 in the initial state is set to adapt to the transport of the housing C).

[0063] If the housing B is in the conveying state, the second adjusting pin 93 contacts and presses against the trigger plate 75. The trigger plate 75 is pressed and moves upward relative to the mounting housing 72. The floating plate 74 moves upward with the trigger plate 75, and the first rack 76 moves upward with the floating plate 74. Under meshing action, the first gear 77 rotates. Under meshing action, the second rack 78 moves, and the pick-up suction cup 73 slides along the sliding groove 722 with the second rack 78, thereby adjusting the position of the pick-up suction cup 73. At the same time, the second gear 81 moves with the pick-up suction cup 73. Under the meshing action of the third rack 79, the second gear 81 rotates, thereby causing the vent valve 80 to rotate and open, expanding the airflow channel and increasing the suction force.

[0064] The conveying process of housing A is the same as that of housing B. However, the first adjusting pin 92 contacts and presses against the trigger plate 75. The trigger plate 75 is pressed and moves a greater distance, which expands the movement range of the pick-up suction cup 73. The vent valve 80 opens wider, and the suction force of the pick-up suction cup 73 is greater, thus adapting to the larger size of the housing.

[0065] The implementation principle of this embodiment is as follows:

[0066] Step 1: Conveying and guiding: The machine casing is conveyed by the first feeding belt 11 and enters the conveying channel 44, where the deviation is corrected by the triangular open section;

[0067] Step 2: Centering Feedback: The lateral centering module 5 adaptively abuts against the side of the housing to achieve dynamic centering and feeds back the size specifications to the linkage module 9;

[0068] Step 3: Linkage Adjustment: The feeding module 7 moves into position, and the linkage module 9, based on the feedback signal, squeezes the trigger plate 75 through the first adjusting pin 92 or the second adjusting pin 93;

[0069] Step 4: Adaptive gripping: The trigger plate 75 moves under force, driving the internal mechanism to adjust the spacing of the pick-up suction cup 73 and the opening degree of the vent valve 80, thus completing adaptive gripping;

[0070] Step 5: Processing and unloading: The housing is transferred to the laser engraving module 3 for processing, and after completion, it is transferred by the unloading module 8 to the second loading belt 12.

[0071] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
