Description

Technical Field

[0001] This invention relates to the field of lighter manufacturing equipment technology, and in particular to an intelligent lighter insert device based on visual recognition. Background Technology

[0002] In the lighter manufacturing process, after the finished lighters are formed, they need to be neatly stored in a special placement tray to complete the batch storage and organization for subsequent packaging, transportation, and warehousing operations. Currently, the industry mostly adopts a continuous conveying combined with fixed-point pushing operation mode for the tray loading of lighters. The conveying equipment completes the continuous feeding of lighters, and then the pushing structure pushes a single row or column of lighters into the slots in the placement tray.

[0003] In continuous palletizing operations, the longitudinal material conveying motion and the lateral defective product rejection and finished product palletizing motions physically intersect. Existing palletizing equipment often uses rigid limiting channels. When performing lateral pushing operations, the lateral pusher directly encroaches on the internal clearance of the longitudinal conveying channel. Conventional anti-interference designs must keep the longitudinal conveying mechanism stationary, disrupting the continuity of the operation. Furthermore, in multi-layer alternating palletizing scenarios, the vertical descent and lateral retraction of pallets between layers require the preceding material-blocking components and push rods to simultaneously clear the palletizing area. Existing equipment often relies on multiple external independent pneumatic cylinders to apply forced unidirectional displacement to each material-blocking component to remove spatial obstructions. This operational logic results in a cumbersome linkage arrangement, and the multi-level cyclical action coordination carries a high risk of collision, making it difficult to provide sufficient mechanical tolerance for inter-layer station switching. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the prior art, such as the interference caused by the lateral removal and loading actions occupying the longitudinal space during the lighter tray loading operation, and the redundant linkage arrangement and overlapping actions with collision risks caused by the existing material blocking components relying on independent external drive sources to avoid obstacles when switching between multiple trays. Therefore, this invention proposes an intelligent lighter tray insertion device based on visual recognition.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent lighter holder device based on visual recognition includes a main frame and a secondary frame, wherein the secondary frame is disposed to the side of the main frame; A workbench is fixedly installed on the top of the main frame, and the workbench serves as the supporting base for the tray loading operation; A conveyor is fixedly mounted on the top of the sub-frame. The conveyor is used to continuously transport lighters, and one end of the conveyor extends to the area above the workbench. The top of the conveyor is equipped with a monitoring component and a pushing component. The monitoring component is located at the upstream station of the conveyor and is used to identify the appearance defects of the lighters during the conveying process and reject defective products. The pushing component is located at the downstream station of the conveyor and is used to push the qualified lighters laterally to complete the insertion assembly. Two electric linear slides I are symmetrically installed on the top of the workbench. Each electric linear slide I is equipped with an electric linear slide III at its sliding end. The electric linear slide III can perform horizontal lateral displacement with the electric linear slide I. The electric linear slide table Ⅲ is laterally slidably equipped with an electric linear slide table Ⅱ, which can realize vertical lifting displacement. The electric linear slide II is equipped with a clamping component on its outer side, and a placement tray is fitted on the inner side of the clamping component. Multiple linear slides work together to precisely adjust the spatial position of the placement tray, thereby completing the layered and continuous tray loading operation of lighters.

[0006] In one possible design, the monitoring component includes a U-shaped frame, which is fixedly installed on one side of the top of the conveyor; A camera is fixedly mounted on the inner wall of the U-shaped frame. The camera's shooting end is set directly towards the material conveying channel of the conveyor, which can collect images of the lighter's appearance in real time during the conveying process and complete the identification and judgment of material quality. Two limiting side plates are symmetrically fixedly installed on the top of the conveyor. The two limiting side plates are respectively located on both sides of the material conveying channel. Each limiting side plate has two corresponding and matching notches inside its plate body. The notches of the two limiting side plates correspond to each other and respectively form a defective product rejection channel and a qualified product pushing passage channel.

[0007] In one possible design, the monitoring component is equipped with an electric push rod I, which is fixedly installed on the outer side wall of the conveyor. The piston rod end of the electric push rod I is fixedly connected to the push plate I. The push plate I is horizontally aligned with the corresponding notch on the limiting side plate and can pass through the notch to complete the lateral pushing action. Two symmetrically arranged fixing rods are fixed on the outer side plate of the limiting side plate. The limiting plate is slidably sleeved on the rod body of the two fixing rods. The limiting plate can slide smoothly along the axial direction of the fixing rods. A blocking block is fixedly installed on the side of the limiting plate facing the notch. The blocking block normally seals the notch at the corresponding position to ensure the normal delivery of the lighter. The ends of the two fixed rods are fixedly connected to a limiting crossbar. Two sets of compression springs I are assembled between the limiting crossbar and the opposite end face of the limiting plate. The compression springs I are sleeved on the outside of the fixed rods. When a defective lighter is pushed and squeezed to block the block, the limit plate can compress the compression spring I to generate displacement, allowing the rejection channel to be opened and the defective product to be discharged. After the material is rejected, the compression spring I rebounds, driving the structure to automatically reset and maintain the channel blockage state.

[0008] In one possible design, the pushing assembly includes an electric push rod II, which is fixedly mounted in a lateral position on the conveyor. The piston rod end of the electric push rod II is fixedly equipped with a push plate II, which is horizontally arranged inside the notch and can accurately push and deliver the lighter into place. The top surface of the limiting side plate is provided with a sliding groove I, and a slider I slides vertically through the inside of the sliding groove I. A compression spring III is fixedly connected between the bottom of the slider I and the bottom wall of the sliding groove I. The compression spring III can drive the slider I to vertically self-reset. The tops of the two sliders I are jointly fixed with a connecting crossbar, which rises and falls synchronously with the sliders I; The connecting crossbar has a vertical through hole inside, and the connecting crossbar also has a sliding groove II on its side. A slider II is slidably fitted inside the sliding groove II. A compression spring II is connected between the slider II and the inner wall of the slide groove II, and a baffle is fixedly installed on the outer side of the slider II; The baffle has an oblique hole inside its body, and a round rod is fitted through the oblique hole and the longitudinal hole. An arc-shaped protrusion is slidably fitted on the outer side of the connecting crossbar, and the arc-shaped protrusion is fixedly connected to the end of the round rod. During the lighter push-out process, the displacement of the top-pushing arc protrusion can drive the round rod linkage baffle to slide laterally, realizing the single-station structure's adaptive avoidance and unlocking, ensuring the orderly completion of the push-out operation.

[0009] In one possible design, a rectangular block is mounted on the side of the conveyor via a fixed connecting rod, and the rectangular block is used to install a reset limiting structure. A baffle is slidably fitted on the top conveying area of ​​the conveyor, and the baffle is located at the lighter receiving station. A return spring is connected between the stop bar and the opposite side of the rectangular block, and the return spring can provide sliding return force for the stop bar; The end of the baffle is provided with a groove Ⅲ, and a slider Ⅲ is vertically slidably mounted inside the groove Ⅲ. A compression spring Ⅳ is mounted between the bottom of the slider Ⅲ and the bottom wall of the groove Ⅲ. A sliding protrusion is fixedly extended on the outer side of the slider III, and a limiting block is fixedly provided on the side of the sliding protrusion; The baffle can provide a front limit for the lighters that have been delivered to the designated position. The sliding protrusion can work with the compression spring IV to achieve adaptive lifting and avoidance during the pushing action. The overall structure can be reset step by step in an orderly manner by relying on the reset spring, which is suitable for continuous pushing operations.

[0010] In one possible design, the clamping assembly includes a U-shaped plate, which is fixedly mounted on the outer side wall of the electric linear slide II; Two side blocks are symmetrically fixed on one side of the U-shaped plate, and two T-shaped rods slide symmetrically through the plate body of the U-shaped plate. A compression spring V is fitted between the T-shaped rod and the inner wall of the U-shaped plate. The compression spring V is normally in a compressed and energy-storing state. The outer ends of the two T-shaped rods are fixedly connected to an L-shaped plate, which is fitted and arranged on the outside of the placement tray. The surface of the placement tray is evenly provided with several slots for inserting lighters, and the two side walls of the placement tray are provided with side grooves that correspond to and match the side blocks. The side grooves and side blocks are engaged and positioned with each other. Compression spring V pushes the T-shaped rod to press the L-shaped plate tightly against the placement tray, ensuring the stability of the tray loading operation. External force can be used to pull the L-shaped plate to release the limit, enabling quick disassembly and replacement of the placement tray.

[0011] In one possible design, a fixed plate is fixedly erected on the top surface of the workbench, and an electric push rod Ⅲ is fixedly installed on the side surface of the fixed plate. A clearance hole is provided inside the workbench. The piston rod end of the electric push rod III is fixedly connected to a connecting plate. The connecting plate is slidably installed through the fixed plate via a guide rod to ensure the stability of lateral sliding. The connecting plate has staggered placement holes and rectangular holes inside, and the placement holes and rectangular holes are interconnected. The placement holes are used for lighters to pass through and insert, and the rectangular holes are used for the baffles to pass through and avoid. The top of the connecting plate is symmetrically fixed with strip blocks, and the ends of the strip blocks are fixedly connected with L-shaped blocks. The bottom of the L-shaped blocks is provided with inclined grooves, and the inclined grooves are adapted to abut against the top end face of the connecting crossbar. The electric push rod III drives the connecting plate to move laterally, which allows the inclined groove to align with the connecting bar, releases the vertical locking limit, and resets all the limiting structures, thus providing the working conditions for the next round of layered tray loading.

[0012] In one possible design, a display screen is fixedly mounted on one side of the top of the main frame, and the display screen is electrically connected to the camera; The display screen can receive and display images of the lighter's appearance captured by the camera in real time, providing intuitive feedback on the material detection status and equipment operating conditions, making it convenient for staff to monitor the equipment's operating status in real time.

[0013] In one possible design, the electric linear slide I, electric linear slide II, and electric linear slide III cooperate with each other to form a three-axis linkage displacement structure. The electric linear slide I is arranged horizontally and is used to drive the overall tray loading station to complete the horizontal switching, realizing the alternation of the station with full trays and empty trays; The electric linear slide III is horizontally arranged on top of the electric linear slide I, and is used to drive the placement tray to make lateral fine-tuning of the alignment and material discharge avoidance. The electric linear slide II is arranged vertically and is used to drive the vertical layering and lifting displacement of the placement tray; The three-axis linkage structure can precisely control the three-dimensional spatial position of the placement tray, ensuring that the multi-layer lighters are accurately inserted layer by layer, effectively guaranteeing the continuous and stable automated tray loading operation of the equipment.

[0014] In this application, during use, the lighter is gradually conveyed forward by a conveyor. A camera can take pictures for visual identification. If the lighter has an appearance defect, the electric push rod I can be activated. The piston rod of the electric push rod I extends and pushes out the defective lighter. Under normal conditions, the blocking block blocks the limiting side plate to ensure that the lighter is conveyed forward normally. When pushed out, the lighter pushes the blocking block, which drives the limiting plate to move. The limiting plate squeezes and compresses the spring I to make room for the lighter. After the lighter leaves the conveyor, it falls downwards and the collection is completed. The qualified lighter continues to be conveyed forward, and its lower half is blocked by the stop bar. At this time, the electric push rod II is activated. The piston rod of the electric push rod II drives the push plate II to move laterally. The push plate II pushes all the sliding protrusions forward, and the push plate II can also push the upper half of the lighter, thus pushing the lighter and all the sliding protrusions together. The lighter will pass through the placement hole and enter the interior of the slot to realize the insertion process. Furthermore, after the sliding protrusion, which is not fed in sync with the lighter, passes through the connecting crossbar, it will contact the connecting crossbar. The sliding protrusion will cause the slider III to move down and squeeze the compression spring IV. Due to the obstruction of the baffle, the subsequent sliding protrusion cannot move up at this time. The position of the sliding protrusion fed in sync with the lighter will be pushed by the lighter to move the arc-shaped protrusion up. The arc-shaped protrusion will cause the round rod to move up inside the longitudinal hole. Since the round rod passes through the oblique hole, the round rod will cause the baffle to move laterally. The sliding protrusion will move out from above the sliding protrusion, making room for the sliding protrusion. At this time, the sliding protrusion and the limiting block can drive the slider III to reset under the elastic force of the compression spring IV. One side of the sliding protrusion moves to the side of the connecting crossbar and cannot continue to reset. The subsequent sliding protrusion and the baffle will reset under the pushing force of the reset spring after the push plate II resets due to the compression of the reset spring. The lighter continues to be delivered to the side of the next stop bar. The electric push rod II is activated again to insert the new lighter into the next slot until all the stops are in a limited position and cannot be reset normally due to the structural limit. At this time, the electric linear slide III is activated. The electric linear slide III drives the placement tray to retract a certain distance, and then the entire layer of lighters is moved out from the corresponding placement hole. The electric linear slide II then drives the whole thing to move down one layer, and the electric linear slide III resets it again to perform the next layer of tray insertion operation. At the same time, the electric push rod III can be activated. The piston rod of the electric push rod III drives the connecting plate to move laterally. The connecting plate drives the two strip blocks to move laterally. The strip blocks drive the L-shaped block to move laterally. At this time, the plane below the L-shaped block no longer abuts against the connecting crossbar. Instead, the inclined groove abuts against the connecting crossbar. At this time, the connecting crossbar and slider I move upward and reset under the elastic force of the compression spring III. At this time, the connecting crossbar no longer blocks the multiple sliding protrusions. The multiple sliding protrusions and the stop bar begin to reset, and the assembly of the next layer continues. Once all the lighters are assembled, the electric linear slide I can be activated. Electric linear slide I drives two electric linear slides III to move, alternating the positions of the empty and full placement trays. The clearance holes allow space for the placement trays. At this point, the L-shaped plate can be pulled, causing the T-shaped rod to move laterally. The T-shaped rod compresses spring V, and the L-shaped plate no longer obstructs the placement tray. The placement tray can then move laterally a short distance, disengaging the side block from the side groove. This allows the placement tray to move multiple lighters out together, facilitating the replacement of the next placement tray and improving work efficiency.

[0015] Beneficial effects: This invention establishes a forced elastic channel constructed from a blocking block, a limiting plate, and a compression spring I. When the pushing plate I laterally pushes the defective product, the defective product acts as a force transmission medium, squeezing the blocking block and forcing the limiting plate to overcome the spring force and retreat. The lateral displacement path of the product itself mechanically releases the lateral physical boundary obstruction. After the defective product is removed, the channel returns to its original position and closes due to mechanical potential energy. The entire side opening and closing process eliminates the kinetic energy dependence on an additional independent driving source and avoids rigid interference between the lateral movement trajectory and the longitudinal material guiding boundary.

[0016] This invention features an adaptive linkage avoidance assembly at the pushing station, consisting of an arc-shaped protrusion, a round rod, a baffle, and slider III. When the lighter is pushed into the insertion position, it contacts the arc-shaped protrusion, triggering a lateral sliding unlock of the baffle via a mechanical linkage. Slider III and related blocking components descend vertically in one direction under spring feedback, allowing longitudinal dimensional margin for subsequent pushing strokes. This linkage avoidance assembly directly converts externally applied lateral thrust into vertical avoidance displacement, reducing the possibility of timing interference caused by multi-node sensing detection.

[0017] This invention employs a three-axis orthogonal translation frame composed of electric linear slides I, II, and III. Combined with the elastic clamping components at the end of the worktable, after the single-layer array insertion period is completed, slide III first retracts laterally to remove the interference overlap area, while slide II then performs interlayer vertical descent to fix the distance. The multi-dimensional orthogonal independent displacement blocks the mechanical interference path between different axial structures, satisfying the high-frequency workstation interchange action of full and empty worktables.

[0018] This invention assembles a transverse connecting plate with inclined grooves and rectangular holes above the workbench. When switching between layer heights, the push rod drives the connecting plate to perform lateral displacement. With the help of the sliding surface of the L-shaped block inclined groove, the connecting crossbar is forced downward to complete the overall vertical lifting. During the interval between periodic actions, the displacement locking limits of the entire row of sliding protrusions and stop bars are released at once, allowing the previously descending material-avoiding stop components to return to their initial elevation by the physical counter-thrust of the compressed spring, thus completing the kinetic energy separation of the pallet loading operation flow and the material-avoiding reset flow.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In one embodiment: Refer to Figure 1-9This embodiment discloses a lighter insertion tray device, including a main frame 1 and a secondary frame 2. The secondary frame 2 is mounted to the side of the main frame 1. A workbench 39 is fixedly mounted on the top of the main frame 1, and a conveyor 4 is fixedly mounted on the top of the secondary frame 2. The conveyor 4 is used to continuously and uniformly transport and load lighters, ensuring a continuous supply of materials for the lighter insertion tray process. Preferably, the conveyor 4 adopts a belt conveyor structure with an anti-slip surface, which can stably support individual lighters for horizontal transport and prevent lighters from shifting or tipping over during transport. A monitoring component is mounted on one side of the top of the conveyor 4 for real-time monitoring and identification of the appearance of the lighters during transport. A pushing component is fixedly mounted on the other side of the top of the conveyor 4, which can laterally push the lighters that have been transported to the designated position to complete the insertion and assembly operation between the lighters and the placement tray 42.

[0023] Specifically, one end of the conveyor 4 extends to the area above the workbench 39. Electric linear slides I5 are fixedly installed on both sides of the top of the workbench 39. Two electric linear slides III7 are slidably mounted on the top of the two electric linear slides I5. Electric linear slides II6 are slidably connected to the lateral position of electric linear slides III7. A placement tray 42 is slidably mounted on the outer side of electric linear slides II6. A clamping assembly is provided on the side of electric linear slides II6, which can stably limit and fix the placement tray 42, ensuring that the placement tray 42 will not shift position during displacement adjustment and insertion operations. Furthermore, during the overall operation of the equipment, the lighters are gradually and uniformly conveyed forward by the conveyor 4. The monitoring component collects real-time image information of the lighters' appearance and completes defect identification and judgment, distinguishing between qualified and defective products, thereby matching the corresponding rejection or traying process.

[0024] Specifically, the monitoring component includes a U-shaped frame 3 fixedly installed on one side of the top of the conveyor 4. A camera 9 is fixedly mounted on the side wall of the U-shaped frame 3, facing the conveyor channel of the conveyor 4, and can completely capture the appearance image of each conveyed lighter. Two sets of symmetrically arranged limiting side plates 17 are fixedly installed on the top of the conveyor 4. Two notches 16 are opened inside the plate body of the limiting side plate 17. The two notches 16 on the same side of the limiting side plate 17 correspond to each other and serve as the defective product rejection channel and the finished product pushing channel, respectively. On this basis, an electric push rod I 10 is fixedly installed on the side of the conveyor 4. The piston rod end of the electric push rod I 10 is fixedly connected to a push plate I 18. The push plate I 18 forms a structural cooperation with one of the notches 16 and can pass through the notches 16 to complete the lateral pushing action.

[0025] Specifically, two sets of symmetrically arranged fixing rods 19 are fixedly mounted on the outer side of the limiting side plate 17. A limiting plate 14 is slidably fitted onto the outer walls of the two sets of fixing rods 19. A blocking block 15 is fixedly mounted on the side of the limiting plate 14 facing the notch 16. The outer dimensions of the blocking block 15 match the corresponding notch 16, enabling normal sealing of the notch 16. Furthermore, a limiting crossbar 12 is fixedly connected to the ends of the two sets of fixing rods 19. Two sets of compression springs I 13 are mounted between the limiting crossbar 12 and the opposite side of the limiting plate 14. The compression springs I 13 are correspondingly fitted onto the outside of the fixing rods 19. Based on this, during normal operation of the equipment, the compression spring I13 remains in a normal pushing state, driving the limiting plate 14 and the blocking block 15 to fit against the notch 16, completing the channel blockage and ensuring the normal forward conveying of lighters. When the camera 9 detects a lighter with an appearance defect, the equipment control system triggers the electric push rod I10 to extend, driving the push plate I18 to push the defective lighter laterally. After the lighter contacts the blocking block 15, it can push the blocking block 15 and the limiting plate 14 to move laterally, squeezing the compression spring I13 to deform, opening up the rejection channel. The defective lighter passes through the notch 16 and leaves the conveyor 4 to complete the automatic rejection. After rejection, the compression spring I13 rebounds and drives the structure to reset, continuing to maintain the channel blockage state.

[0026] Specifically, the pushing component includes an electric push rod II11 fixedly installed on the side of the conveyor 4. A push plate II23 is fixedly mounted on the piston rod end of the electric push rod II11. The push plate II23 is correspondingly arranged in the internal area of ​​one of the notches 16 and corresponds to the position of the notch 16 on the other side, allowing for precise alignment with the lighter being pushed into position. A groove I24 is provided on the top surface of the limiting side plate 17. A slider I33 is slidably mounted inside the groove I24. A compression spring III34 is fixedly mounted between the bottom end face of the slider I33 and the bottom inner wall of the groove I24, enabling the slider I33 to self-adaptively rise and fall and reset. A connecting crossbar 22 is fixedly connected to the top of both sets of sliders I33. Multiple longitudinal holes 27 are opened along the longitudinal direction inside the crossbar 22. Multiple sets of grooves II28 are opened on the side end face of the connecting crossbar 22, and sliders II30 are slidably mounted inside the grooves II28.

[0027] Furthermore, a compression spring II31 is installed between the side wall of slider II30 and the inner side wall of slide groove II28. A baffle 29 is fixedly installed on the side of slider II30 away from the compression spring II31. An oblique hole 32 is opened inside the baffle 29. The oblique hole 32 and the longitudinal hole 27 are connected by the same round rod 26. The side of the connecting bar 22 is slidably fitted with an arc-shaped protrusion 25 through the slider slide rail structure. The end of the arc-shaped protrusion 25 is fixedly connected to one end of the round rod 26. When the external force triggers the displacement of the arc-shaped protrusion 25, it can drive the round rod 26 to slide along the longitudinal hole 27 and the oblique hole 32, thereby driving the baffle 29 to complete the lateral displacement and realize structural avoidance. After qualified lighters are continuously delivered to the pushing station, the electric push rod II11 extends and drives the push plate II23 to move laterally, simultaneously pushing the lighters and corresponding limiting structures to complete the insertion of the lighters into the placement tray 42. During the process, each elastic structure completes adaptive deformation and reset with the pushing action to meet the requirements of continuous pushing operations.

[0028] Specifically, a rectangular block 58 is mounted on the side of the conveyor 4 via a fixed connecting rod. A stop bar 21 is slidably mounted at the top conveying channel position of the conveyor 4. The stop bar 21 can slide laterally along the top surface of the conveyor 4. A return spring 57 is fixedly mounted between the opposite sides of the stop bar 21 and the rectangular block 58, and the return spring 57 can realize the normal self-adaptive return of the stop bar 21. A groove Ⅲ38 is opened at the end of the stop bar 21. A slider Ⅲ36 is slidably mounted inside the groove Ⅲ38. A compression spring Ⅳ37 is mounted between the bottom of the slider Ⅲ36 and the bottom inner wall of the groove Ⅲ38. A sliding protrusion 20 is fixedly mounted on the outside of the slider Ⅲ36. A limiting block 35 is fixedly connected to the side end of the sliding protrusion 20. Preferably, the sliding protrusion 20 is made of wear-resistant engineering plastic material, which has stable sliding performance and wear resistance, and can be adapted to repeated sliding avoidance operations for a long time.

[0029] After the lighter is delivered to its position, the stop bar 21 can limit and block the lower half of the lighter. Combined with the pushing force of the push plate II 23 on the upper half of the lighter, it ensures that the lighter moves smoothly and laterally and is accurately inserted into the corresponding work station structure to complete the insertion. During the pushing process, after the sliding protrusion 20 of the unmatched lighter pushing work station contacts the connecting bar 22, it can drive the slider III 36 to move down along the slide groove III 38, compressing the compression spring IV 37 to produce compression deformation. Relying on the limiting and blocking effect of the stop plate 29, the displacement state of the subsequent sliding protrusion 20 is restricted. The sliding protrusion 20 of the matched lighter pushing work station can be pushed up by the lighter to move the arc protrusion 25, which drives the round rod 26 to slide laterally in conjunction with the stop plate 29, making room for the sliding channel. This allows the corresponding sliding protrusion 20 to be reset under the elastic force of the compression spring IV 37, completing the structural adaptation of the single-wheel insertion operation. After a single push is completed, the push plate II 23 resets, and the stop bar 21 and sliding protrusion 20 gradually reset under the elastic force of the reset spring 57, waiting for the next round of operation instructions.

[0030] Specifically, the clamping assembly includes a U-shaped plate 53 fixedly installed on the side of the electric linear slide II 6. Two side blocks 56 are symmetrically fixedly mounted on one side of the U-shaped plate 53. Two sets of symmetrically arranged T-shaped rods 55 are slidably mounted inside the U-shaped plate 53. Two sets of symmetrically arranged compression springs V 54 are mounted between the rod body of the T-shaped rods 55 and the inner side wall of the U-shaped plate 53. The outer ends of the two sets of T-shaped rods 55 are fixedly connected to an L-shaped plate 52, which can provide lateral limiting constraint for the placement tray 42. Multiple evenly arranged slots 51 are opened inside the tray 42 for corresponding insertion and fixing of lighters. Multiple sets of side grooves 50 are opened on both side walls of the placement tray 42. The side grooves 50 can engage with the side blocks 56 to achieve positioning and limiting of the placement tray 42. Preferably, the placement tray 42 is made of hard alloy material, which has high overall structural strength, is not easily deformed, and can stably support a large number of lighters for a long time.

[0031] During equipment operation, the compression spring V54 remains in a normal pushing state, causing the T-shaped rod 55 and L-shaped plate 52 to fit against the outer side of the placement tray 42. This, combined with the engaging structure of the side block 56 and the side groove 50, ensures the placement tray 42 is stably fixed from all directions, preventing displacement or shaking during layered insertion operations. When the placement tray 42 needs to be replaced, the L-shaped plate 52 is pulled laterally, causing the T-shaped rod 55 to slide and compress the compression spring V54. This disengages the L-shaped plate 52 from the limiting area of ​​the placement tray 42, releasing the positioning constraint. The placement tray 42 can then be moved horizontally, disengaging the side groove 50 from the side block 56, allowing for quick full tray disassembly and empty tray replacement.

[0032] Specifically, a fixed plate 49 is fixedly mounted on the top of the workbench 39, and an electric push rod III 48 is fixedly mounted on the side of the fixed plate 49. The piston rod end of the electric push rod III 48 is fixedly connected to a connecting plate 40. The connecting plate 40 is slidably installed through the fixed plate 49 via a guide rod to ensure the stability of the lateral displacement of the connecting plate 40. Multiple placement holes 43 and rectangular holes 44 are opened inside the connecting plate 40. The placement holes 43 and rectangular holes 44 are staggered and adjacent and connected. The diameter of the placement holes 43 matches the outer diameter of the lighter, allowing the lighter to pass through and be inserted. The size of the rectangular holes 44 is adapted to the baffle 21, which can meet the insertion and avoidance requirements of the baffle 21. Two strip blocks 45 are symmetrically fixedly mounted on the top side of the connecting plate 40. The ends of the strip blocks 45 are fixedly connected to L-shaped blocks 46. The bottom of the L-shaped blocks 46 has a sloping groove 47, which can form a slope fit with the connecting crossbar 22.

[0033] After the single-layer lighter insertion operation is completed, the electric push rod Ⅲ48 can drive the connecting plate 40 to move laterally as a whole, and simultaneously drive the strip block 45 and L-shaped block 46 to move, so that the planar limiting structure at the bottom of the L-shaped block 46 is separated from the connecting horizontal bar 22, and the inclined groove 47 is in contact with the connecting horizontal bar 22. Relying on the slope structure of the inclined groove 47 to adapt to the vertical displacement of the connecting horizontal bar 22, the slider Ⅰ33 and the connecting horizontal bar 22 are reset upward under the elastic force of the compression spring Ⅲ34, releasing the limiting obstruction of the sliding protrusion 20. All the stop bars 21 and sliding protrusions 20 complete the reset action, the equipment structure returns to the initial working position state, and the next layer of lighter insertion operation can be started.

[0034] Based on this, after the single-row, single-layer lighters are inserted and filled into slot 51, the electric linear slide III7 starts operating, driving the placement tray 42 to retract laterally by the corresponding distance, allowing the inserted lighters to smoothly exit from the placement hole 43 and escape the limit constraint. Subsequently, the electric linear slide II6 drives the placement tray 42 to move vertically downward by the height of a single layer, completing the layer alignment. The electric linear slide III7 then resets, returning the placement tray 42 to the insertion position to begin the insertion operation of the next layer of lighters. After all multi-layer insertion operations are completed, the electric linear slide I5 starts, driving the two sets of electric linear slide III7 to move laterally, realizing the alternation of the positions of the empty placement tray 42 and the full placement tray 42. With the quick disassembly and assembly structure of the clamping components, the full tray unloading and empty tray loading are completed, continuously cycling through the batch lighter tray loading operation.

[0035] This device has an open mechanical transmission structure. After long-term operation, the sliding parts and elastic reset components need to be cleaned, dusted, and lubricated regularly to effectively prevent structural jamming and reset failure, and ensure the continuous and stable operation of the equipment.

[0036] This application can be used in the field of lighter manufacturing equipment, or in other fields applicable to this application.

[0037] In another embodiment: Reference Figure 1-9 An intelligent lighter insert device based on visual recognition is used in the field of lighter production equipment. The structure of this embodiment is basically the same as that of the previous embodiment. The difference is that a display screen 8 is fixedly installed on one side of the top of the main frame 1. The display screen 8 is electrically connected to the camera 9 and can display the lighter appearance image collected by the camera 9 in real time. It can intuitively show the material detection status, so that the staff can keep abreast of the equipment operation and material detection status in real time and ensure that the entire insert device can continuously and stably complete the automated insert operation.

[0038] It is also equipped with a controller, which is electrically connected to the electric linear slide I5, electric linear slide II6, electric linear slide III7, electric push rod I10, electric push rod II11, electric push rod III48, camera 9, and display screen 8. The controller is used to coordinate the timing actions of each electrical component to realize the fully automated control of visual recognition detection, defective product rejection, lighter push tray loading, layer displacement, and automatic structural reset.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller, electric linear slide I5, electric linear slide II6, electric linear slide III7, electric push rod I10, electric push rod II11, electric push rod III48, camera 9, and display screen 8 are all conventional methods or common knowledge, and will not be described in detail here.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
