Description

Technical Field

[0001] This invention belongs to the field of lighter housing production technology, and more specifically, relates to an automatic loading and stacking structure for lighter housing production. Background Technology

[0002] The lighter casing production line is a complete production system integrating injection molding, cooling and shaping, edge grinding, packaging and assembly. It typically uses ABS resin and other plastics as the core raw materials, uses specialized molds to shape the casing, and then achieves mass production of the casing through continuous processing and quality inspection. Its core function is to produce standardized and efficient lighter casing components, ensuring that the casing has the structural precision and appearance consistency to adapt to subsequent processes such as filling and assembly. This significantly reduces the error rate of manual operation and production costs. At the same time, it connects the upstream and downstream links of the entire lighter production, forming a complete manufacturing chain to meet the market's demand for large-scale supply of lighter products.

[0003] The Chinese patent publication number is CN111099344A, which discloses a material handling device for a lighter assembly line. Compared with the prior art, this invention utilizes the contact between the abutment block and the lighter casing to realize the transfer of the lighter casing, which can effectively reduce the probability of damage to the lighter casing and thus effectively improve the finished quality of the lighter.

[0004] Existing lighter casings have the following disadvantages during production: 1. After the lighter casings are initially packaged and placed into the trays, they usually need to be moved manually. This not only requires a significant investment of manpower, but also affects the smoothness of the production process due to differences in the rhythm of manual operation. In addition, during manual handling, improper operation can easily cause the lighter trays to shift, which will cause inconvenience to subsequent stacking operations and may also interfere with the robotic arm's gripping of objects for loading and unloading, affecting the efficiency and accuracy of loading and unloading. 2. When stacking manually, the stacking height is difficult to reach the set requirements due to the height limitation of the operator. Moreover, as the stacking height increases, it is difficult for the operator to accurately control the stacking position of each layer of slotted plates, which can easily lead to the center of gravity of the overall stacking structure shifting, thereby causing the risk of collapse and affecting the integrity of the product and the continuity of production. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an automated loading and stacking structure for lighter casing production.

The production platform is equipped with a guiding mechanism for easy guidance, and a stacking mechanism for easy stacking. The guiding mechanism includes a fixed upright and a longitudinal drive motor. The stacking mechanism includes a transfer storage plate, an L-shaped side rod, rubber adsorption grooves, and a servo motor. The fixed upright is fixedly installed at the upper end of the production platform. The longitudinal drive motor is located at the side end of the fixed upright. The transfer storage plate is located at the side end of the production platform. The L-shaped side rod is fixedly installed at the side end of the transfer storage plate. Each rubber adsorption groove is fixedly installed through the upper end of the transfer storage plate. Two servo motors are respectively fixedly installed at the two sides of the transfer storage plate. A pre-processing module is provided at the upper end of the production platform. A stacking transfer box is provided at the side end of the production platform. A rectangular slide rail is fixedly installed at the upper end of the fixed upright. A transverse drive motor is also fixedly installed at the upper end of the fixed upright and on one side of the rectangular slide rail. The output end of the transverse drive motor is fixedly installed with... A transverse threaded rod is located on the inner wall of a rectangular slide rail. A C-shaped slider is slidably mounted on the inner wall of the rectangular slide rail. A transverse threaded groove is formed through the side end of the C-shaped slider. The transverse threaded rod is threadedly mounted on the inner wall of the transverse threaded groove. A longitudinal upright is fixedly mounted on the side end of the C-shaped slider. A longitudinal drive motor is fixedly mounted on the lower end of the longitudinal upright. A longitudinal threaded rod is fixedly mounted on the output end of the longitudinal drive motor. A connecting block is fixedly mounted on the upper end of the transfer storage plate. A movable plate is fixedly mounted on the upper end of the connecting block. The movable plate is slidably mounted on the inner wall of the C-shaped slider. A longitudinal threaded groove is formed through the upper end of the movable plate. The longitudinal threaded rod is threadedly mounted on the inner wall of the longitudinal threaded groove. A clearance groove is formed through the side end of the inner wall of the transfer storage plate. A light sensor is fixedly mounted on the inner wall of the clearance groove. A cylinder is fixedly mounted on the side end of the L-shaped side rod. The cylinder is interlocked through the side end of the transfer storage plate. A push plate is fixedly mounted on the side end of the cylinder.

[0007] Preferably, the rubber adsorption tank array is located on the inner side wall of the transfer storage plate, and multiple air chambers are fixedly installed at the lower end of the transfer storage plate. The position of each air chamber corresponds to each row of rubber adsorption tanks, and an air pump is fixedly installed at the side end of each air chamber.

[0008] Preferably, a rotating rod is fixedly installed at the output end of each of the two servo motors, and a positioning plate is fixedly installed at the circumferential end of each of the two rotating rods.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a horizontal drive motor, a vertical drive motor, a transfer storage plate, and a stacking transfer box are provided to stack lighter slots to a set height according to production needs. The horizontal and vertical drive motors drive the transfer storage plate to move through a threaded transmission, which can precisely control the relative position of the transfer storage plate and the stacking transfer box, ensuring the accurate stacking position of each slot. This helps maintain the stability of the center of gravity of the overall stacking structure, reduces the possibility of collapse, and provides a stable working environment for the robotic arm to grasp and unload objects, avoiding the impact of stacking structure shaking on the robotic arm's grasping accuracy.

[0010] In this invention, a pre-processing module, a transfer storage plate, a horizontal drive motor, a vertical drive motor, a cylinder, and a pusher plate are used to achieve automatic transfer and stacking of lighter slot plates. After the pre-processing module completes the initial assembly and packaging of the lighter shell and the slot plate, the slot plate can be directly received by the transfer storage plate. Then, the horizontal and vertical drive motors are precisely driven to adjust the position. Finally, the cylinder pushes the pusher plate to complete the stacking action. The entire process requires no manual handling and stacking, reducing manpower input. At the same time, it is easy to coordinate with the process of a robotic arm grasping and loading objects, so that the robotic arm's picking and placing actions can be seamlessly connected with the automatic stacking process, improving the smoothness of the production process and facilitating the continuity of production.

[0011] In this invention, an air chamber, an air pump, and a rubber adsorption groove are used in combination to stably fix the lighter tray during temporary storage. After the air pump is started, it delivers negative pressure suction to the rubber adsorption groove through the air chamber. The rubber adsorption groove can fit tightly against the bottom of the lighter tray, thereby ensuring accurate positioning of the tray and preventing the tray from shifting due to equipment movement or slight external disturbances. This reduces deviations during stacking, ensuring the accuracy of the robotic arm's loading and unloading of objects, and allowing the robotic arm to accurately identify the tray position when docking with relevant processes.

[0012] In this invention, a servo motor and a positioning plate are used to limit the movement of the already stacked slots when a new lighter slot is being stacked. As the pusher plate pushes the new slot into the stacking transfer box, the servo motor rotates the positioning plate to both sides of the already stacked slots. The positioning plate maintains an appropriate distance from the already stacked slots, preventing them from contacting each other. This also prevents the already stacked slots from shaking or collapsing due to the impact of the new slot being pushed in, further ensuring the stability of the stacking process and making the working environment more stable when the robotic arm is handling and loading / unloading objects.

[0013] In this invention, a light sensor and an air pump work together. The light sensor detects the position of the lighter slot and drives the air pump. The air pump only starts to generate negative pressure when the lighter slot is fully in the preset position and blocks the light sensor. This triggering method improves operational accuracy, reduces the probability of accidental activation, and the entire process has a high degree of automation. It can reduce manual intervention, facilitate the maintenance of production continuity, and also support the efficient operation of the robotic arm in picking up and unloading objects, allowing the robotic arm's operating rhythm to be consistent with the automatic stacking process.

Detailed Implementation

[0016] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0017] Please see Figure 1 - Figure 8This invention provides an automatic loading and stacking structure for lighter casing production, including a production platform 1. The production platform 1 is equipped with a guiding mechanism for easy guidance, and a stacking mechanism for easy stacking. The guiding mechanism includes a fixed support frame 2 and a longitudinal drive motor 3. The stacking mechanism includes a transfer storage plate 4, L-shaped side rods 5, rubber adsorption grooves 6, and servo motors 7. The fixed support frame 2 is fixedly installed at the upper end of the production platform 1. The longitudinal drive motor 3 is located at the side end of the fixed support frame 2. The transfer storage plate 4 is located at the side end of the production platform 1. The L-shaped side rods 5 are fixedly installed at the side end of the transfer storage plate 4. Each rubber adsorption groove 6 is fixedly installed through the upper end of the transfer storage plate 4. Two servo motors 7 are respectively... Fixedly installed on both sides of the transfer storage plate 4, the upper end of the production platform 1 is provided with a pre-processing module 11, and the side end of the production platform 1 is provided with a stacking transfer box 12. During normal use, the pre-processing module 11 on the production platform 1 provides a working basis for the placement of lighter shells. The equipment on the pre-processing module 11 inserts the lighter shells one by one into the lighter slot plate. A lighter slot plate can accommodate multiple lighter shells. After the initial packaging is completed, the lighter slot plate gradually moves to the side end of the transfer storage plate 4 under the transmission of the belt. At this time, the belt conveyor mechanism and the matching drive structure on the pre-processing module 11 work together to guide the lighter slot plates into the inner area of ​​the transfer storage plate 4 in batches. A rectangular slide rail 21 is fixedly installed on the upper end of the fixed frame 2. A transverse drive motor 22 is also fixedly installed on the upper end of the fixed frame 2 and on one side of the rectangular slide rail 21. A transverse threaded rod 23 is fixedly installed on the output end of the transverse drive motor 22. The transverse threaded rod 23 is located on the inner wall of the rectangular slide rail 21. A C-shaped slider 33 is slidably installed on the inner wall of the rectangular slide rail 21. A transverse threaded groove 34 is opened through the side end of the C-shaped slider 33. The transverse threaded rod 23 is threadedly installed on the inner wall of the transverse threaded groove 34. A longitudinal upright 31 is fixedly installed on the side end of the C-shaped slider 33. A longitudinal drive motor 3 is fixedly installed on the lower end of the longitudinal upright 31. A longitudinal threaded rod 32 is fixedly installed on the output end of the longitudinal drive motor 3. A connecting block 41 is fixedly installed on the upper end of the connecting block 41. A movable plate 42 is fixedly installed on the upper end of the connecting block 41. The movable plate 42 is slidably installed on the inner wall of the C-shaped slider 33. A longitudinal threaded groove 43 is opened through the upper end of the movable plate 42. The longitudinal threaded rod 32 is threadedly installed on the inner wall of the C-shaped slider 33. The transverse threaded groove 43 is mounted on the inner wall of the transverse storage plate 4. A clearance groove 45 is provided through the side end of the inner wall of the transverse storage plate 4. A light sensor 46 is fixedly installed on the inner wall of the clearance groove 45. After the temporary storage and adsorption positioning of multiple rows of lighter slot plates are completed in the transverse storage plate 4, the equipment starts the position adjustment process to achieve precise transfer to the stacked transfer box 12. First, the transverse drive motor 22 at the upper end of the fixed stand 2 starts, driving the transverse threaded rod 23 at its output end to rotate at a constant speed. The transverse threaded rod 23 and C The transverse threaded groove 34 at the side end of the C-shaped slider 33 forms a threaded engagement. Under the guidance and constraint of the rectangular slide rail 21, the C-shaped slider 33 moves smoothly laterally along the rectangular slide rail 21. At the same time, the longitudinal drive motor 3 on the longitudinal upright 31 at the side end of the C-shaped slider 33 starts synchronously, driving the longitudinal threaded rod 32 at its output end to rotate. The longitudinal threaded rod 32 engages with the longitudinal threaded groove 43 at the upper end of the movable plate 42, driving the movable plate 42 to move precisely longitudinally along the inner wall of the C-shaped slider 33. Since the movable plate 42 is fixedly connected to the transfer storage plate 4 through the connecting block 41, under the synergistic effect of the transverse and longitudinal movements, the transfer storage plate 4 carries the temporarily stored lighter slot plate and gradually moves to the preset target stacking position above the stacking transfer box 12. A cylinder 51 is fixedly installed at the side end of the L-shaped side rod 5. The cylinder 51 is interlocked with the side end of the transfer storage plate 4. A push plate 52 is fixedly installed at the side end of the cylinder 51. After reaching the target stacking position, the air pump 62 stops its suction operation, and the negative pressure state in the air chamber 61 and the rubber adsorption groove 6 is gradually released. The adsorption effect of the rubber adsorption groove 6 on the lighter slot plate disappears. Subsequently, the horizontal drive motor 22 starts again, driving the horizontal threaded rod 23 to rotate, causing the C-shaped slider 33 to move backward away from the stacking transfer box 12. The transfer storage plate 4 moves backward synchronously with the C-shaped slider 33, making room for the push of the lighter slot plate. During this backward movement, the cylinder 51 at the side end of the L-shaped side rod 5 starts synchronously, pushing the push plate 52 to slowly extend towards the stacking transfer box 12. The end face of the push plate 52 makes smooth contact with the side of the lighter slot plate, pushing the lighter slot plates in the transfer storage plate 4 one by one smoothly into the stacking transfer box 12. The rubber adsorption grooves 6 array is located on the inner wall of the transfer storage plate 4. Multiple air chambers 61 are fixedly installed at the lower end of the transfer storage plate 4. The position of each air chamber 61 corresponds to each row of rubber adsorption grooves 6. An air pump 62 is fixedly installed on the side end of each air chamber 61. When a row of lighter slots fully enters the preset position within the transfer storage plate 4 under the action of the driving device, the bottom of the lighter slot will block the light sensor 46 in the avoidance groove 45, and simultaneously completely cover the corresponding row of rubber adsorption grooves 6. The light sensor 46 detects a continuous blocking signal. Then, a start command is immediately sent to the air pump 62 corresponding to that column. The air chamber 61 connected to the rubber adsorption tank 6 of that column then enters the working state. After the air pump 62 starts, it continuously delivers negative pressure suction to the rubber adsorption tank 6 through the air chamber 61. The rubber adsorption tank 6 fits tightly with the bottom of the lighter slot plate with its own elastic material, effectively avoiding negative pressure leakage, and thus forming a stable adsorption on the lighter slot plate. This achieves accurate positioning of the lighter slot plate in the transfer storage plate 4, providing a stable foundation for subsequent moving operations and avoiding positional deviation due to bumps or inertia during the movement. Both servo motors 7 have rotating rods 71 ​​fixedly installed at their output ends, and positioning plates 72 are fixedly installed at the circumferential ends of both rotating rods 71. While the push plate 52 pushes the lighter slot plates to stack, the servo motors 7 at both ends of the transfer storage plate 4 respond and start synchronously. The output ends of the servo motors 7 drive the rotating rods 71 ​​to rotate to a preset angle. The rotating rods 71 ​​then drive the positioning plates 72 to rotate to the positions on both sides of the stacked lighter slot plates in the stacking transfer box 12. The positioning plates 72 maintain an appropriate distance from the stacked lighter slot plates and do not make direct contact. At the same time, they form an effective limit to prevent the impact force generated when the new slot plate is pushed in from causing the stacked slot plates to shake or tip over, thus ensuring the stability of the stacking process.

[0018] Working principle: In the first step, during normal use, the pre-processing module 11 on the production platform 1 provides the working basis for placing the lighter shells. The equipment on the pre-processing module 11 inserts the lighter shells one by one into the lighter slot plate. One lighter slot plate can accommodate multiple lighter shells. After the initial packaging is completed, the lighter slot plate gradually moves to the side end of the transfer storage plate 4 under the transmission of the belt. At this time, the belt conveyor mechanism and the matching drive structure on the pre-processing module 11 work together to guide the lighter slot plates into the inner area of ​​the transfer storage plate 4 in batches.

[0019] In the second step, once a row of lighter slots has fully entered the preset position within the transfer storage plate 4 under the action of the driving device, the bottom of the lighter slot will block the light sensor 46 in the clearance groove 45, and simultaneously fully cover the corresponding row of rubber adsorption grooves 6. After the light sensor 46 detects the continuous blocking signal, it immediately sends a start command to the air pump 62 corresponding to that row. The air chamber 61 connected to the rubber adsorption groove 6 then enters the working state. After the air pump 62 starts, it continuously delivers negative pressure suction to the rubber adsorption groove 6 through the air chamber 61. The rubber adsorption groove 6, with its own elastic material, fits tightly against the bottom of the lighter slot, effectively preventing negative pressure leakage, thereby forming a stable adsorption on the lighter slot, achieving precise positioning of the lighter slot within the transfer storage plate 4, providing a stable foundation for subsequent moving operations, and avoiding positional shifts due to bumps or inertia during the movement.

[0020] The third step involves temporarily storing and absorbing multiple rows of lighter slots within the transfer storage plate 4, then adjusting the equipment position to achieve precise transfer to the stacked transfer box 12. First, the horizontal drive motor 22 at the upper end of the fixed stand 2 starts, driving the horizontal threaded rod 23 at its output end to rotate at a constant speed. The horizontal threaded rod 23 and the horizontal threaded groove 34 at the side end of the C-shaped slider 33 form a threaded engagement. Under the guidance and constraint of the rectangular slide rail 21, the C-shaped slider 33 moves smoothly laterally along the rectangular slide rail 21. At the same time, the longitudinal drive motor 3 on the longitudinal stand 31 at the side end of the C-shaped slider 33 starts synchronously, driving the longitudinal threaded rod 32 at its output end to rotate. The longitudinal threaded rod 32 and the longitudinal threaded groove 43 at the upper end of the movable plate 42 form a threaded engagement, driving the movable plate 42 to move precisely longitudinally along the inner wall of the C-shaped slider 33. Since the movable plate 42 is fixedly connected to the transfer storage plate 4 through the connecting block 41, under the combined action of horizontal and vertical movement, the transfer storage plate 4 carries the temporarily stored lighter slot plate and gradually moves to the preset target stacking position above the stacking transfer box 12. This application utilizes a combination of a horizontal drive motor 22, a vertical drive motor 3, a transfer storage plate 4, and a stacking transfer box 12 to stack lighter trays to a set height according to production needs. The horizontal drive motor 22 and the vertical drive motor 3 drive the transfer storage plate 4 through a threaded transmission, which can precisely control the relative position of the transfer storage plate 4 and the stacking transfer box 12, ensuring the accurate stacking position of each tray. This helps maintain the stability of the overall stacking structure's center of gravity, reduces the possibility of collapse, and provides a stable working environment for the robotic arm to grasp and unload objects, avoiding the impact of stacking structure swaying on the robotic arm's grasping accuracy.

[0021] Fourth, after reaching the target stacking position, the air pump 62 stops its suction operation, and the negative pressure in the air chamber 61 and the rubber adsorption groove 6 is gradually released. The adsorption effect of the rubber adsorption groove 6 on the lighter slot plate disappears. Subsequently, the horizontal drive motor 22 starts again to drive the horizontal threaded rod 23 to rotate, causing the C-shaped slider 33 to move backward away from the stacking transfer box 12. The transfer temporary storage plate 4 moves backward synchronously with the C-shaped slider 33 to make room for the push of the lighter slot plate. During this retraction process, the cylinder 51 at the side end of the L-shaped side rod 5 is activated simultaneously, pushing the push plate 52 to slowly extend towards the stacking transfer box 12. The end face of the push plate 52 makes smooth contact with the side of the lighter slot plate, pushing the lighter slot plates in the transfer storage plate 4 one by one smoothly into the stacking transfer box 12. While the push plate 52 pushes the lighter slot plates to stack, the servo motors 7 at both ends of the transfer storage plate 4 are activated simultaneously. The output end of the servo motor 7 drives the rotating rod 71 to rotate to a preset angle. The rotating rod 71 then drives the positioning plate 72 to rotate to the positions on both sides of the already stacked lighter slot plates in the stacking transfer box 12. The positioning plate 72 maintains an appropriate distance from the already stacked lighter slot plates, without direct contact, and at the same time forms an effective limit to prevent the impact force generated when the new slot plate is pushed in from causing the already stacked slot plates to shake or tip over, thus ensuring the stability of the stacking process. After completing one stacking operation, cylinder 51 drives push plate 52 to quickly reset, servo motor 7 drives positioning plate 72 to rotate back to the initial position, and transfer storage plate 4 returns to the initial storage position under the coordinated action of horizontal drive motor 22 and vertical drive motor 3, ready to receive the next batch of lighter slot plates. This cycle repeats to achieve continuous and stable stacking of lighter slot plates. This application utilizes a pre-processing module 11, a transfer storage plate 4, a horizontal drive motor 22, a vertical drive motor 3, a cylinder 51, and a push plate 52 to achieve automatic transfer and stacking of lighter slot plates. After the pre-processing module 11 completes the initial assembly and packaging of the lighter housing and slot plate, the slot plate can be directly received by the transfer storage plate 4. The horizontal drive motor 22 and the vertical drive motor 3 then precisely drive the slot plate to adjust its position. Finally, the cylinder 51 pushes the push plate 52 to complete the stacking action. The entire process requires no manual handling or stacking, reducing manpower input. It also facilitates integration with the robotic arm's object grabbing and unloading process, allowing the robotic arm's picking and placing actions to seamlessly connect with the automatic stacking process, improving the smoothness of the production process and promoting production continuity. This application utilizes an air chamber 61, an air pump 62, and a rubber adsorption groove 6 to stably fix the lighter tray during temporary storage. After the air pump 62 is activated, it delivers negative pressure suction to the rubber adsorption groove 6 through the air chamber 61. The rubber adsorption groove 6 tightly adheres to the bottom of the lighter tray, ensuring accurate positioning of the tray and preventing positional shifts due to equipment movement or minor external disturbances. This reduces deviations during stacking, ensuring the precision of the robotic arm's loading and unloading of objects and allowing the robotic arm to accurately identify the tray's position during relevant processes. This application employs a servo motor 7 and a positioning plate 72 to limit the movement of the already stacked slots when a new lighter slot is being stacked. During the process of the pusher plate 52 pushing the new slot into the stacking transfer box 12, the servo motor 7 can rotate the positioning plate 72 to both sides of the already stacked slots. The positioning plate 72 maintains an appropriate distance from the already stacked slots, preventing them from contacting each other. This also prevents the already stacked slots from shaking or collapsing due to the impact of the new slot being pushed in, further ensuring the stability of the stacking process and making the working environment more stable when the robotic arm is handling objects. This application employs a light sensor 46 and an air pump 62 in conjunction. The light sensor 46 detects the position of the lighter slot plate and drives the air pump 62. The air pump 62 only activates to generate negative pressure when the lighter slot plate is fully in the preset position and blocks the light sensor 46. This triggering method improves operational accuracy, reduces the probability of accidental activation, and achieves a high degree of automation in the entire process. It reduces manual intervention, facilitates the maintenance of production continuity, and also supports the efficient operation of the robotic arm for loading and unloading objects, allowing the robotic arm's operating rhythm to be consistent with the automatic stacking process.
