Description

Technical Field

[0001] This invention relates to the field of lid and spoon assembly technology, and specifically to a fully automated lid and spoon assembly line. Background Technology

[0002] Traditionally, the folding spoons included inside the dust covers of canned foods are mostly two-fold spoons. While this two-fold spoon has a relatively simple structure and offers some convenience in production and use, its limited handle length makes it inconvenient for consumers in certain situations and fails to meet diverse usage needs. Against this backdrop, the three-fold spoon emerged. With its longer handle, the three-fold spoon is more convenient for consumers and has gradually replaced the original two-fold spoon. However, the extra fold in the handle inevitably increases the difficulty of assembling the lid.

[0003] Currently, the industry commonly uses lid-and-spoon assembly lines to assemble folding spoons and dust covers. However, most existing lid-and-spoon assembly lines are custom-designed for two-fold spoons, and their assembly processes and mechanical structures are not well-suited to the installation requirements of three-fold spoons. Furthermore, existing lid-and-spoon assembly lines still rely heavily on manual labor for loading the folding spoons and dust covers. Workers need to place the folding spoons and dust covers into designated loading positions and then start the assembly equipment. This semi-automatic production method is inefficient, cannot meet the needs of large-scale production, and the repetitive nature of the work can easily lead to worker fatigue, affecting subsequent assembly quality and potentially causing the spoons to be insecurely installed.

[0004] In conclusion, in order to adapt to the widespread use of three-fold spoons and improve the production efficiency and assembly quality of spoon lid assembly, it is necessary to develop a fully automated assembly line for three-fold spoon lids. Summary of the Invention

[0005] (a) Technical problems to be solved This invention provides a fully automated assembly line for a spoon and lid, which can at least solve the technical problem of how to improve the production efficiency and assembly quality of the three-fold spoon and dust cover.

[0006] (II) Technical Solution To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fully automatic assembly line for a lid and spoon, comprising: frame; The lifting mechanism, turning mechanism, and assembly conveyor line are all mounted on the frame. The lifting mechanism is used to continuously supply dust covers with the opening facing upwards one by one. The turning mechanism is connected to the discharge end of the lifting mechanism and is positioned opposite to the feed end of the assembly conveyor line. The turning mechanism is used to receive the dust covers supplied by the lifting mechanism and transfer them to the assembly conveyor line, as well as to adjust the slots of the dust covers so that they face a preset direction. The frame is equipped with at least two pressing spoon stations corresponding to the assembly conveyor line. The assembly conveyor line is used to transport the adjusted dust covers to the corresponding pressing spoon stations and to transport the dust covers that have been pressed out of the corresponding pressing spoon stations. The spoon feeding mechanism and fixture are both located on the frame. The spoon feeding module is used to feed the three-fold spoon onto the fixture. The fixture is located above the assembly conveyor line. The fixture is equipped with at least two three-fold spoon feeding stations for placing and limiting a single three-fold spoon. The number of three-fold spoon feeding stations and spoon pressing stations are the same and are set up one-to-one. The spoon pressing mechanism is located on the machine frame. It is used to transfer and fold the three-fold spoons from several three-fold spoon feeding stations into the slots of the dust cover of the corresponding spoon pressing station.

[0007] Further configuration: at least two parallel assembly conveyor lines are arranged at intervals, and at least two discharge ends of the turning mechanism and lifting mechanism are provided accordingly. Several pressing spoon stations corresponding to the same assembly conveyor line are grouped together, and the number of pressing spoon stations in each group is at least two.

[0008] Further, the aforementioned fixture includes at least one placement rack, the number of which is the same as that of the assembly conveyor line, and they are arranged in a one-to-one correspondence. The placement rack is provided with at least two three-fold spoon feeding stations. The number of three-fold spoon feeding stations on the same placement rack is the same as the number of spoon pressing stations corresponding to the same assembly conveyor line, and they are all arranged at intervals along the conveying direction of the assembly conveyor line. The placement rack is used to place the three-fold spoons. Each three-fold spoon feeding station on the placement rack is provided with a wedge-shaped limiting groove, which is used to insert and limit the spoon part of the three-fold spoon.

[0009] In a further embodiment, the aforementioned fixture also includes a placement rack drive assembly, which is mounted on the frame and is connected to at least one placement rack via a transmission connection. The placement rack drive assembly is used to drive the lifting and lowering movement of at least one placement rack.

[0010] Further, the aforementioned spoon-pressing mechanism includes a transfer drive assembly, an adjustment drive assembly, and at least two adsorption assemblies. The transfer drive assembly is mounted on the frame, and the adsorption assemblies and adjustment drive assembly are both mounted on the output end of the transfer drive assembly. The number of adsorption assemblies is the same as the number of spoon-pressing stations corresponding to the same assembly conveyor line, and they are arranged in a one-to-one correspondence. At least two adsorption assemblies are arranged along the conveying direction of the assembly conveyor line. The adsorption assemblies are used to adsorb or release the spoon part of the three-fold spoon. The adjustment drive assembly is driven to move away from or towards each other, so that the adsorption assemblies are positioned relative to the corresponding spoon-pressing station or limiting groove. The transfer drive assembly is used to drive the adjustment drive assembly and the adsorption assemblies to reciprocate between the fixture and the assembly conveyor line to grab one of the three-fold spoons on the placement rack and fold it into the slot of the dust cover of the corresponding spoon-pressing station.

[0011] Further, the aforementioned spoon feeding mechanism includes a clamp and a clamp driving module. The clamp is provided with at least one set of suction nozzles at intervals. The number of suction nozzles in the same set is the same as the number of three-fold spoon feeding stations on the same placement rack, and they are set one-to-one. The suction nozzles are used to adsorb or release the middle handle of a single three-fold spoon. The clamp driving module is located on the frame and is connected to the clamp for transmission. The clamp driving module is used to drive the clamp to move relative to the fixture so as to place and confine the three-fold spoon adsorbed by one set of suction nozzles on the corresponding three-fold spoon feeding station.

[0012] Further, the aforementioned lifting mechanisms include: The material handling conveyor line is located on the frame. The material handling conveyor line is used to screen dust covers and supply dust covers with the opening facing outwards. Both the material sorting conveyor and the feeding conveyor are mounted on the frame. The material sorting conveyor has at least one material sorting inlet and at least two material sorting outlets. At least one material sorting inlet is connected to the discharge end of the material sorting conveyor. The number of material sorting outlets, feeding conveyors, and turning mechanisms are the same and they are set up one-to-one. The inlet end of the feeding conveyor is connected to the corresponding material sorting outlet, and the outlet end is connected to the corresponding turning mechanism. The material sorting conveyor is used to receive dust covers supplied by the material sorting conveyor and then input the dust covers into at least two feeding conveyors, with the openings of the dust covers facing upwards. The feeding conveyor is used to continuously and sequentially transport several dust covers to the corresponding turning mechanism.

[0013] Furthermore, the aforementioned assembly conveyor line has at least two adjustment stations at the feed end for placing a single dust cover, and the at least two adjustment stations are arranged at equal intervals along the conveying direction of the assembly conveyor line. The steering mechanism includes a first adjustment module and a second adjustment module. Both the first and second adjustment modules are mounted on the frame and are positioned opposite to the feed end of the assembly conveyor line. The first adjustment module is also connected to the discharge end of the feeding conveyor line. The first adjustment module is used to receive several dust covers with their openings facing upwards, which are conveyed by the feeding conveyor line, and to position the dust covers at several adjustment stations on the assembly conveyor line. The second adjustment module is used to rotate the dust covers at the adjustment stations so that the slots of the dust covers face a preset direction.

[0014] (III) Beneficial Effects Compared with the prior art, the fully automatic assembly line for lids and spoons provided by the present invention has the following advantages: 1. When using the fully automatic assembly line for spoons and lids provided by this invention, firstly, the lifting mechanism outputs a set of dust covers with their openings facing upwards to the turning mechanism. The turning mechanism then transports these dust covers to the assembly conveyor line, adjusting the slots of each dust cover to face a preset direction. Next, the assembly conveyor line transports the adjusted dust covers to each spoon-pressing station. Simultaneously, the spoon feeding mechanism feeds the three-fold spoons to the three-fold spoon feeding station of the fixture. Then, the spoon-pressing mechanism folds and presses one set of three-fold spoons from the fixture into the slots of the corresponding dust covers at the spoon-pressing station. Finally, the assembly conveyor line transports the set of pressed dust covers out of the spoon-pressing station and transports the next set of adjusted dust covers to the vacated spoon-pressing station. It can be seen that this invention, through the coordinated operation of various mechanisms, achieves fully automatic feeding and assembly of three-fold spoons and dust covers, effectively improving production efficiency, reducing manual operation, lowering labor costs and human error, thereby ensuring the stability of product quality.

[0015] 2. In the material loading and assembly process, this invention achieves dual precision control through the ingenious cooperation of a steering mechanism and a fixture. The steering mechanism precisely adjusts the loading position of the dust cover and the orientation of the slot, while the fixture restricts the loading position of the three-fold spoon, achieving precise loading of both the dust cover and the three-fold spoon. This further improves assembly accuracy and quality, significantly increasing the product yield. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a fully automated assembly line for a spoon and lid, which addresses the problem of improving the production efficiency and assembly quality of the three-fold spoon 9 and the dust cover 8.

[0020] See Figure 1 , Figure 3 and Figure 4 As shown, Figure 1 This is a 3D view of the fully automated assembly line for the lid and spoon in the embodiment. Figure 3 This is a schematic diagram of the structure of the frame, assembly conveyor line, fixture, and pressure spoon mechanism in the embodiment. Figure 4 for Figure 3 The enlarged schematic diagram at point B shows that the fully automatic assembly line for the lid and spoon includes a frame 1, a lifting mechanism 2, a turning mechanism 3, an assembly conveyor line 4, a spoon feeding mechanism 5, a fixture 6, and a spoon pressing mechanism 7.

[0021] The lifting mechanism 2, the turning mechanism 3, and the assembly conveyor line 4 are all mounted on the frame 1. The lifting mechanism 2 continuously supplies dust covers 8 with their openings facing upwards. The turning mechanism 3 connects to the discharge end of the lifting mechanism 2 and is positioned opposite to the feed end of the assembly conveyor line 4. The turning mechanism 3 receives the dust covers 8 supplied by the lifting mechanism 2, transfers them to the assembly conveyor line 4, and adjusts the slots 81 of the dust covers 8 to face a preset direction. The frame 1 has at least two pressing stations 11 corresponding to the assembly conveyor line 4. The assembly conveyor line 4 transports the adjusted dust covers 8 to the corresponding pressing stations 11 and transports the pressed dust covers 8 out of the corresponding pressing stations 11.

[0022] Both the spoon feeding mechanism 5 and the fixture 6 are mounted on the frame 1. The spoon feeding module is used to feed the three-fold spoon 9 onto the fixture 6. The fixture 6 is located above the assembly conveyor line 4, and it has at least two three-fold spoon feeding stations 61 for placing and limiting a single three-fold spoon 9. The number of three-fold spoon feeding stations 61 and the number of spoon pressing stations 11 are the same, and they are set up one-to-one.

[0023] The spoon pressing mechanism 7 is installed on the frame 1. The spoon pressing mechanism 7 is used to transfer and fold the three-fold spoons 9 of several three-fold spoon feeding stations 61 into the slots 81 of the dust cover 8 of the corresponding spoon pressing station 11.

[0024] When the fully automatic assembly line for lids and spoons using the above technical solution is in use, firstly, the lifting mechanism 2 outputs a set of dust covers 8 with the lid opening facing upwards to the turning mechanism 3. The turning mechanism 3 conveys the set of several dust covers 8 to the assembly conveyor line 4 and adjusts the slots 81 of each dust cover 8 to face the preset direction. Then, the assembly conveyor line 4 conveys the set of adjusted dust covers 8 to each spoon pressing station 11. At the same time, the spoon feeding mechanism 5 feeds the three-fold spoons 9 to the three-fold spoon feeding station 61 of the fixture 6. Then, the spoon pressing mechanism 7 folds one set of three-fold spoons 9 on the fixture 6 and presses them into the slots 81 of the dust covers 8 in the corresponding spoon pressing station 11. Finally, the assembly conveyor line 4 conveys the set of dust covers 8 that have been pressed out of the spoon pressing station 11 and conveys the next set of adjusted dust covers 8 to the empty spoon pressing station 11.

[0025] As can be seen from the above usage process, compared with the prior art, the present invention has the following advantages: 1) Through the coordinated operation of various mechanisms, this invention achieves fully automatic feeding and assembly of the three-fold spoon 9 and the dust cover 8, which effectively improves production efficiency, reduces manual operation, lowers labor costs and human error, thereby ensuring the stability of product quality.

[0026] 2) In the material loading and assembly process, the present invention achieves dual precision control through the ingenious cooperation of the steering mechanism 3 and the fixture 6. The steering mechanism 3 can precisely adjust the loading position of the dust cover 8 and the orientation of the slot 81, while the fixture 6 can restrict the loading position of the three-fold spoon 9, thereby achieving precise loading of the dust cover 8 and the three-fold spoon 9, which further improves the assembly accuracy and quality, and significantly increases the product yield.

[0027] The assembly conveyor line 4 described above can use existing belt conveyor mechanisms.

[0028] See Figure 1 As shown, based on the above embodiment, at least two assembly conveyor lines 4 are distributed in parallel at intervals. The turning mechanism 3 and the lifting mechanism 2 each have at least two discharge ends. Several pressing spoon stations 11 corresponding to the same assembly conveyor line 4 are grouped together, with at least two groups of pressing spoon stations 11. Thus, the arrangement of multiple assembly conveyor lines 4 and their supporting mechanisms allows for the simultaneous assembly of multiple sets of lid spoons, further improving production efficiency and meeting the needs of large-scale production.

[0029] See Figure 3 and Figure 4As shown, in one embodiment of the fixture 6, the fixture 6 includes at least one placement rack 62. The number of placement racks 62 is the same as that of the assembly conveyor line 4, and they are arranged in a one-to-one correspondence. The placement rack 62 is provided with at least two three-fold spoon loading stations 61. The number of three-fold spoon loading stations 61 on the same placement rack 62 is the same as the number of pressing stations 11 corresponding to the same assembly conveyor line 4, and they are all arranged at intervals along the conveying direction of the assembly conveyor line 4. The placement rack 62 is used to place the three-fold spoon 9. Each three-fold spoon loading station 61 of the placement rack 62 has a wedge-shaped limiting groove 63. The limiting groove 63 is used to insert and limit the spoon part 91 of the three-fold spoon 9. In this way, when the three-fold spoon 9 is placed on the placement rack 62, it is inserted into the wedge-shaped limiting groove 63, thereby playing a stable positioning role. The positioning method is simple and easy to implement, which can effectively ensure the consistency of the loading position of the three-fold spoon 9, thereby improving the subsequent pressing accuracy.

[0030] The aforementioned limiting groove 63 can also be in other tapered shapes such as a pyramid. In this way, the spoon part 91 of the three-fold spoon 9 can be stably positioned simply by inserting it into the limiting groove 63.

[0031] See Figure 4 As shown, based on the above-described embodiment of fixture 6, fixture 6 further includes a placement rack drive assembly 64. The placement rack drive assembly 64 is mounted on the frame 1 by means of screwing or welding, and its output end is connected to at least one placement rack 62 by means of screwing or welding. The placement rack drive assembly 64 is used to drive the lifting and lowering movement of at least one placement rack 62. Thus, when the three-fold spoons 9 are fed, firstly, the spoon feeding module transfers the spoon parts 91 of several three-fold spoons 9 to above the corresponding limiting slots 63; then, the placement rack drive assembly 64 drives the placement rack 62 to rise, so that the spoon parts 91 of several three-fold spoons 9 can be inserted into the corresponding limiting slots 63 together, and the several three-fold spoons 9 can be placed on the corresponding placement rack 62 together, ensuring that the spoon parts 91 of each three-fold spoon 9 can be inserted into place, thereby efficiently and accurately completing the feeding of several three-fold spoons 9; next, the assembly stage begins, the spoon pressing mechanism 7 grabs a group of spoon parts 91 of three-fold spoons 9, and at the same time, the placement rack drive assembly 64 drives the placement rack 62 to descend, so that the spoon parts 91 of the group of three-fold spoons 9 can be moved out of the corresponding limiting slots 63 together, realizing the rapid unloading of several three-fold spoons 9. After unloading is completed, the spoon pressing mechanism 7 can transfer the grabbed three-fold spoons 9 to the designated position and fold the three-fold spoons 9 into the slots 81 of the corresponding spoon pressing station 11. It can be seen that the fixture 6, through the placement rack drive component 64, can work with the spoon feeding module and the spoon pressing mechanism 7 to accurately complete the loading and unloading of several three-fold spoons 9, providing a solid guarantee for the smooth progress of the entire assembly process.

[0032] The aforementioned placement rack drive assembly 64 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles.

[0033] See Figure 3 and Figure 5 As shown, Figure 5This is a schematic diagram of the spoon-pressing mechanism in one embodiment. The spoon-pressing mechanism 7 includes a transfer drive assembly 71, an adjustment drive assembly 72, and at least two adsorption assemblies 73. The transfer drive assembly 71 is mounted on the frame 1 by screwing or welding. The adsorption assemblies 73 and the adjustment drive assembly 72 are both mounted on the output end of the transfer drive assembly 71 by screwing or welding. The number of adsorption assemblies 73 and the number of spoon-pressing stations 11 corresponding to the same assembly conveyor line 4 are the same, and they are arranged in a one-to-one correspondence. At least two adsorption assemblies 73 are arranged along the conveying direction of the assembly conveyor line 4. The adsorption assemblies 73 are used to adsorb or release the spoon portion 91 of the three-fold spoon 9. The adjustment drive assembly 72 is drively connected to at least two adsorption assemblies 73. The adjustment drive assembly 72 is used to drive each adsorption assembly 73 to move away from or closer to each other, so that the adsorption assemblies 73 are positioned relative to the corresponding limiting groove 63 or the spoon-pressing station 11. The transfer drive assembly 71 drives the distance adjustment drive assembly 72 and the adsorption assembly 73 to reciprocate between the fixture 6 and the assembly conveyor line 4, in order to grasp the three-fold spoon 9 on one of the placement racks 62 and fold it into the slot 81 of the dust cover 8 of the corresponding spoon pressing station 11. Thus, when the spoon pressing mechanism 7 is in use, firstly, the assembly conveyor line 4 transports several dust covers 8 with their openings facing upwards to several spoon pressing stations 11; simultaneously, the transfer drive assembly 71 drives the adsorption assembly 73 to move towards the fixture 6. At this time, the center distance between two adjacent adsorption assemblies 73 is equal to the center distance between two adjacent limiting grooves 63, that is, each adsorption assembly 73 is positioned one-to-one with the corresponding limiting groove 63; then, after the adsorption assembly 73 adsorbs the spoon portion 91 of the three-fold spoon 9 on the corresponding limiting groove 63, the transfer drive assembly 71 drives the adsorption assembly 73 (in cooperation with the placement rack drive assembly 64). The three-fold spoon 9 is moved out of the fixture 6 and towards the corresponding pressing spoon station 11. At the same time, the distance adjustment drive assembly 72 drives each adsorption assembly 73 to move away from each other so that the center distance between two adjacent adsorption assemblies 73 is equal to the center distance between two adjacent pressing spoon stations 11, so that each adsorption assembly 73 is aligned with the slot 81 of the dust cover 8 of the corresponding pressing spoon station 11. Then, the transfer drive assembly 71 drives the adsorption assembly 73 to press the tail handle 93, middle handle 92 and spoon part 91 of the three-fold spoon 9 into the slot 81 of the corresponding pressing spoon station 11 in sequence, thus completing the folding and pressing of a set of three-fold spoons 9. Finally, the adsorption component 73 releases the spoon part 91, and the assembly conveyor line 4 sends the assembled dust cover 8 out of the pressing spoon station 11. At the same time, the next set of dust covers 8 to be assembled is sent into several pressing spoon stations 11. At this time, the distance adjustment drive component 72 drives each adsorption component 73 to move closer to each other, so that each adsorption component 73 is aligned with the corresponding limiting groove 63. The above operation process is repeated to realize the folding and pressing of the next set of three-fold spoons 9.It can be seen that the spoon pressing mechanism 7, through the coordinated cooperation of the transfer drive component 71, the distance adjustment drive component 72 and at least two adsorption components 73, can automatically and simultaneously complete the precise folding and spoon pressing operations of multiple three-fold spoons 9, realize the high-quality assembly of multiple three-fold spoons 9 with the dust cover 8, effectively improve the assembly efficiency and quality, and reduce labor costs.

[0034] The aforementioned transfer drive assembly 71 can be driven by a combination of an existing robotic arm or flipping mechanism and a three-axis moving mechanism / two-axis moving mechanism, enabling the adsorption assembly 73 and the distance adjustment drive assembly 72 to move and flip flexibly in three-dimensional space, thereby enabling the transfer and folding pressing of the three-fold spoon 9.

[0035] See Figure 5 As shown, in one embodiment of the pitch adjustment drive assembly 72, the pitch adjustment drive assembly 72 includes a slide plate 721 and a slide plate drive component 722. The slide plate drive component 722 is mounted on the frame 1 by means of screwing or welding, and its output end is connected to the slide plate 721 by means of screwing or welding. At least two adsorption components 73 are arranged along the conveying direction of the assembly conveyor line 4. Among them, one of the adsorption components 73 at the beginning and end is fixed to the output end of the transfer drive assembly 71 by means of screwing or welding, and the other is fixed to the slide plate 721 by means of screwing or welding. Both the adsorption component 73 in the middle are slidably connected to the output end of the transfer drive assembly 71. A first connecting rod 723 and a second connecting rod 724 are rotatably connected to the adsorption component 73. The first connecting rod 723 and the second connecting rod 724 are distributed intersectingly. The first connecting rods 723 of each adsorption component 73 are arranged in parallel with each other, and the second connecting rods 724 of each adsorption component 73 are arranged in parallel with each other. The top ends of the first connecting rods 723 and the top ends of the second connecting rods 724 of two adjacent adsorption components 73 in the same group are rotatably connected, and the bottom ends of the first connecting rods 723 and the bottom ends of the second connecting rods 724 of two adjacent adsorption components 73 are rotatably connected, forming a parallelogram structure. The slide plate drive component 722 is used to drive the slide plate 721 to slide, so as to adjust the center distance between adjacent adsorption components 73, thereby making the adsorption components 73 relative to the corresponding limiting grooves 63 or the pressure spoon station 11. Thus, the adjustable drive assembly 72, through the cooperation of the slide plate 721 and the slide plate drive component 722, can drive the adsorption assembly 73 at the tail end or the head end to slide towards or away from the adsorption assembly 73 at the head end or the tail end. During this sliding process, the adsorption assembly 73 at the tail end or the head end, through the linkage design of the parallelogram structure, can drive the adsorption assembly 73 in the middle to slide accordingly, thereby playing the role of precisely adjusting the center distance between adjacent adsorption assemblies 73, effectively ensuring the relative positional accuracy between each adsorption assembly 73, and greatly improving the assembly efficiency.

[0036] The aforementioned skateboard drive unit 722 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles.

[0037] See Figure 5 As shown, in one embodiment of the adsorption assembly 73, the adsorption assembly 73 includes a limiting seat 731 and a suction rod 732. The limiting seat 731 is provided on the output end of the transfer drive assembly 71 by means of screwing or welding. One side of the spoon portion 91 has a connecting portion 911 for rotatably connecting with the middle handle 92 of the three-fold spoon 9. The limiting seat 731 has a clearance slot 733 for the connecting portion 911 to be inserted. The suction rod 732 is provided on the limiting seat 731 by means of screwing or welding, and the suction rod 732 is used to abut against and adsorb the spoon portion 91. Thus, when grasping the three-fold spoon 9 on the fixture 6, the transfer drive assembly 71 drives the adsorption assembly 73 to move toward the corresponding limiting groove 63, so that the suction rod 732 abuts against the spoon part 91 on the limiting groove 63. At the same time, the connecting part 911 of the spoon part 91 is inserted into the clearance slot 733, effectively limiting the position of the spoon part 91 on the adsorption assembly 73. Then, the suction rod 732 is activated to adsorb the abutting spoon part 91. Finally, the transfer drive assembly 71 drives the adsorption assembly 73 to move the adsorbed spoon part 91 out of the limiting groove 63, completing the precise grasping of the three-fold spoon 9. As can be seen, the adsorption component 73, through the design of the suction rod 732 and the clearance slot 733, can firmly adsorb the spoon part 91 of the three-fold spoon 9 and play a precise positioning and limiting role for the spoon part 91. This ensures that the position of the spoon part 91 on the limiting seat 731 will not move or shift during the transfer and assembly process, thus affecting the subsequent assembly accuracy. This further improves the stability and accuracy of the three-fold spoon 9 during the pressing process and ensures the assembly quality.

[0038] The aforementioned suction rod 732 can be connected to an external air extraction device or a negative pressure adsorption device to provide adsorption force.

[0039] See Figure 3 and Figure 4 As shown, based on the above embodiment of the spoon pressing mechanism 7, the spoon pressing mechanism 7 further includes a first pressing block 74, a second pressing block 75, and a pressing block driving assembly 76. The first pressing block 74 and the second pressing block 75 both extend along the conveying direction of the assembly conveyor line 4 and are relatively distributed on both sides of several spoon pressing stations 11. The pressing block driving assembly 76 is mounted on the frame 1 by screwing or welding and is drively connected to the first pressing block 74 and / or the second pressing block 75. The pressing block driving assembly 76 is used to drive the first pressing block 74 and the second pressing block 75 to move towards or away from each other to clamp or release the dust covers 8 of several spoon pressing stations 11. Thus, under the drive of the pressing block driving assembly 76, the first pressing block 74 and the second pressing block 75 can stably clamp and release the dust covers 8 of several spoon pressing stations 11, ensuring that the dust covers 8 remain fixed during the process of pressing the three-fold spoon 9 into the dust cover 8 slot 81, thereby further improving the assembly accuracy and success rate. Meanwhile, this clamping and positioning design can also adapt to dust covers 8 of different sizes, enhancing the versatility of the spoon pressing mechanism 7.

[0040] One of the aforementioned first pressure block 74 and second pressure block 75 can be fixed to the frame 1 by means of screwing or welding, and the other can be connected to the output end of the pressure block drive assembly 76 by means of screwing or welding. The pressure block drive assembly 76 can use an existing linear drive mechanism such as a telescopic cylinder or telescopic pole. Alternatively, both the first pressure block 74 and second pressure block 75 can be connected to the output end of the pressure block drive assembly 76 by means of screwing or welding. The pressure block drive assembly 76 can use an existing bidirectional displacement mechanism such as a motor-bidirectional lead screw nut.

[0041] See Figure 1 and Figure 2 As shown, Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that, in one embodiment of the spoon feeding mechanism 5, the spoon feeding mechanism 5 includes a clamp 51 and a clamp driving module 52. At least one set of suction nozzles 53 are spaced apart on the clamp 51 by means of screwing or welding. The number of the same set of suction nozzles 53 is the same as the number of three-fold spoon feeding stations 61 on the same placement rack 62, and they are arranged in a one-to-one correspondence. The suction nozzles 53 are used to adsorb or release the middle handle 92 of a single three-fold spoon 9. The clamp driving module 52 is mounted on the frame 1 by means of screwing or welding, and its output end is connected to the clamp 51 for transmission. The clamp driving module 52 is used to drive the clamp 51 to move relative to the fixture 6, so as to place and confine the three-fold spoon 9 adsorbed by one set of suction nozzles 53 on the corresponding three-fold spoon feeding station 61. In this way, the spoon feeding mechanism 5, through the cooperation of the clamp 51 and the clamp drive module 52, can accurately feed several sets of three-fold spoons 9 to the corresponding three-fold spoon feeding station 61 of the fixture 6, ensuring the accuracy and stability of the feeding and providing a reliable foundation for the subsequent spoon pressing process.

[0042] The aforementioned clamp drive module 52 can be driven by a combination of an existing robotic arm or flipping mechanism and a three-axis moving mechanism / two-axis moving mechanism, enabling the clamp 51 to move and flip flexibly in three-dimensional space, thereby enabling the loading and transfer of the three-fold spoon 9.

[0043] like Figure 1 and Figure 2As shown, in this embodiment, there are four sets of both the placement rack 62 and the suction nozzle 53. The limiting grooves 63 of the two left placement racks 62 face to the left, and the limiting grooves 63 of the two right placement racks 62 face to the right. The spoon parts 91 of the three-fold spoons 9 held by the two sets of suction nozzles 53 on the left and the two sets of suction nozzles 53 on the right are arranged in opposite directions. In this way, the clamp driving module 52 only needs to move the two sets of suction nozzles 53 on the left to above the two sets of right placement racks 62, and move the two sets of right suction nozzles 53 to above the two sets of left placement racks 62, to insert the spoon parts 91 of the three-fold spoons 9 held by the two sets of suction nozzles 53 on the left into the limiting grooves 63 of the two sets of right placement racks 62, and to insert the spoon parts 91 of the three-fold spoons 9 held by the two sets of right suction nozzles 53 into the limiting grooves 63 of the two sets of left placement racks 62. This symmetrical design can effectively prevent interference between the clamp 51 and the placement rack 62.

[0044] See Figure 1 and Figure 6 As shown, Figure 6 This is a partial structural diagram of the frame and lifting mechanism (after removing the outer shell) in one embodiment. In one implementation of the lifting mechanism 2, the lifting mechanism 2 includes a material handling conveyor line 21, a material distribution conveyor line 22, and a material feeding conveyor line 23 mounted on the frame 1. The material handling conveyor line 21 is used to screen dust covers 8 and supply dust covers 8 with their openings facing outwards. The material distribution conveyor line 22 has at least one material distribution inlet 221 and at least two material distribution outlets 222. At least one material distribution inlet 221 is connected to the outlet end of the material handling conveyor line 21. The number of material distribution outlets 222, the material feeding conveyor line 23, and the turning mechanism 3 are the same, and they are arranged in a one-to-one correspondence. The inlet end of the material feeding conveyor line 23 is connected to the corresponding material distribution outlet 222, and the outlet end is connected to the corresponding turning mechanism 3. The material distribution conveyor line 22 receives the dust covers 8 supplied by the material handling conveyor line 21 and then feeds the dust covers 8 into at least two material feeding conveyor lines 23, with the openings of the dust covers 8 facing upwards. The feeding conveyor line 23 is used to continuously and sequentially transport several dust covers 8 to the corresponding turning mechanism 3. Thus, the lifting mechanism 2, through the sorting conveyor line 21, can initially sort and transport the dust covers 8, adjusting the disordered dust covers 8 to an outward-facing position. The sorting conveyor line 22 can then rationally distribute the outward-facing dust covers 8 to multiple feeding conveyor lines 23, adjusting the outward-facing dust covers 8 to an upward-facing position. The feeding conveyor line 23 can then continuously and sequentially transport the dust covers 8, grouping the upward-facing dust covers 8 to the corresponding turning mechanism 3 for turning operations, further adjusting the feeding position of the dust covers 8. It can be seen that the lifting mechanism 2, through the cooperation of the sorting conveyor line 21, the sorting conveyor line 22, and the feeding conveyor line 23, achieves full automation of the dust cover 8 feeding process, thereby significantly improving feeding efficiency and accuracy.

[0045] The aforementioned material distribution conveyor line 22 can be assembled using existing aluminum plates or other panels, and the material feeding conveyor line 23 can be constructed using existing belt conveyor mechanisms.

[0046] See Figure 1 and Figure 6 As shown, in one embodiment of the material handling conveyor line 21, the material handling conveyor line 21 includes a lifting conveyor belt 211, a hopper 212, and a first air blowing assembly 213. The lifting conveyor belt 211 is mounted on the frame 1 by means of screwing or welding, and is used to convey dust covers 8. The lifting conveyor belt 211 includes a feeding section 2111, a screening section 2112, and a discharging section 2113 connected sequentially from bottom to top. The screening section 2112 extends vertically upward, and part of the screening section 2112 protrudes outward. The screening section 2112 is used to screen the dust covers 8 with their openings facing inward onto the feeding section 2111. The hopper 212 is mounted on the frame 1 by means of screwing or welding, and is located above the feeding section 2111. The hopper 212 is used to supply dust covers 8 in batches to the feeding section 2111. The first air-blowing assembly 213 is mounted on the frame 1 by screwing or welding, and is located above the discharge section 2113. The first air-blowing assembly 213 blows the dust covers 8 on the discharge section 2113 into the corresponding material inlet 221. Thus, when the material handling conveyor line 21 is in use, firstly, the worker pours a batch of disordered dust covers 8 into the hopper 212, and the dust covers 8 automatically fall from the hopper 212 to the loading section 2111 area of ​​the lifting conveyor belt 211; then, the lifting conveyor belt 211 carries the dust covers 8 from the loading section 2111 area along... Figure 6 The dust cover 8 is conveyed to the screening section 2112 area in the direction of the arrow. Since the center of gravity of the dust cover 8 is on the cover plate away from the opening, when the dust cover 8 with the opening facing inward is conveyed to the screening section 2112, especially the protrusion of the screening section 2112, the dust cover 8 with the opening facing inward will deflect outward from the screening section 2112 under its own gravity and fall back to the feeding section 2111 area, thus playing the role of screening dust cover 8; at the same time, the lifting conveyor belt 211 will carry the dust cover 8 with the opening facing outward in the screening section 2112 area along... Figure 6 The material is conveyed to the discharge section 2113 area in the direction of the arrow. The first air blowing assembly 213 blows the dust cover 8 on the discharge section 2113 along... Figure 6 The air is blown into the corresponding material distribution inlet 221 in the direction of the arrow for material distribution. It can be seen that the material handling conveyor line 21, through the cooperation of the lifting conveyor belt 211, hopper 212, and first air blowing component 213, can adjust the disordered dust covers 8 to an outward-facing position and convey them to the material distribution conveyor line 22, improving the automation level and conveying accuracy of the material handling conveyor line 21 and reducing the workload of manual screening and handling. The special structure of the screening section 2112 enables the screening of dust covers 8 by their orientation, rejecting dust covers 8 with inward-facing openings, ensuring that only dust covers 8 with outward-facing openings can be conveyed to the material distribution conveyor line 22.

[0047] The aforementioned lifting conveyor belt 211 can use an existing belt elevator, and the aforementioned first air blowing assembly 213 can use an existing air blowing device.

[0048] See Figure 1 and Figure 6 As shown, based on the above-described embodiment of the material handling conveyor line 21, a plurality of protrusions 2114 are evenly distributed on the lifting conveyor belt 211. A U-shaped trough 2115 with openings at both ends is formed between two adjacent protrusions 2114. The width of the trough 2115 is equal to the outer diameter of the dust cover 8, and the depth is equal to the thickness of the dust cover 8. The frame 1 includes a limiting cover 12. The limiting cover 12 covers the discharge section 2113 and is used to close the opening of the trough 2115 of the discharge section 2113. A discharge port 2116 is formed between the limiting cover 12 and the lifting conveyor belt 211. The discharge port 2116 is opposite to and connected to one end opening of the trough 2115 of the discharge section 2113, and is also connected to at least one material distribution inlet 221. The first air blowing assembly 213 is mounted on the limiting cover 12 by means of screwing or welding. The first air blowing assembly 213 has a first air blowing hole 2131 communicating with the discharge port 2116. The first air blowing hole 2131 extends obliquely downward along the length of the material trough 2115 toward the discharge port 2116. The first air blowing assembly 213 is used to blow the dust cover 8 on the discharge section 2113 to move along the corresponding material trough 2115 toward the discharge port 2116, thereby moving it from the discharge port 2116 into the corresponding material dispensing inlet 221. In this way, the trough 2115 formed by the lifting conveyor belt 211 and the protrusion 2114 can accurately accommodate a single row of dust covers 8, so as to avoid the dust covers 8 overlapping during conveying; while the limiting cover 12 can restrict the dust covers 8 on the discharge section 2113 to the corresponding trough 2115, ensuring that the dust covers 8 on the discharge section 2113 can only move along the corresponding trough 2115 under the blowing of the first air blowing component 213, realizing the accurate transfer of the dust covers 8 from the lifting conveyor belt 211 to the material distribution conveyor line 22, improving the accuracy and stability of the conveying, and reducing the falling and misalignment of the dust covers 8 during the conveying process.

[0049] See Figure 1 , Figure 7 and Figure 8 As shown, Figure 7 This is a partial structural diagram of the frame, steering mechanism, and assembly conveyor line in the embodiment. Figure 8This is a partial structural diagram of the steering mechanism and assembly conveyor line in an embodiment. In one implementation of the steering mechanism 3, the steering mechanism 3 includes a first adjustment module 31 and a second adjustment module 32. Both the first adjustment module 31 and the second adjustment module 32 are mounted on the frame 1 and are positioned opposite to the feed end of the assembly conveyor line 4. The first adjustment module 31 is also connected to the discharge end of the feeding conveyor line 23. The feed end of the assembly conveyor line 4 is provided with at least two adjustment stations 41 for placing a single dust cover 8, and the at least two adjustment stations 41 are arranged at equal intervals along the conveying direction of the assembly conveyor line 4. The first adjustment module 31 is used to receive a plurality of dust covers 8 with their openings facing upwards conveyed by the feeding conveyor line 23, and to confine the plurality of dust covers 8 to the plurality of adjustment stations 41 of the assembly conveyor line 4. The second adjustment module 32 is used to rotate the dust covers 8 on the plurality of adjustment stations 41 so that the slots 81 of the dust covers 8 face a preset direction. Thus, when the steering mechanism 3 is in use, firstly, the feeding conveyor line 23 inputs several dust covers 8 with their openings facing upwards into the first adjustment module 31. The first adjustment module 31 places and confines the dust covers 8 on the corresponding adjustment station 41 of the assembly conveyor line 4, ensuring that each dust cover 8 can be accurately positioned, laying a solid foundation for subsequent operations. Then, the second adjustment module 32 simultaneously rotates the dust covers 8 on each adjustment station 41, so that the slots 81 of the dust covers 8 on each adjustment station 41 are accurately facing the preset direction, meeting the strict requirements for lid and spoon assembly. Finally, the assembly conveyor line 4 sends all the dust covers 8 that have been accurately adjusted on the adjustment stations 41 together into the spoon pressing station 11 for lid and spoon assembly operations. It can be seen that the steering mechanism 3, through the first adjustment module 31 and the second adjustment module 32, can automatically and accurately adjust the positions of multiple dust covers 8 on the assembly conveyor line 4, as well as the orientation of the slots 81 of the dust covers 8. This not only greatly improves production efficiency but also effectively improves the loading position accuracy of the dust covers 8, thereby significantly improving the accuracy of the pressing spoon and the product quality. In this embodiment, the preset orientation of the slots 81 is perpendicular to the conveying direction of the assembly conveyor line 4, such as... Figure 8 As shown in the figure, the slot 81 of the dust cover 8 faces the preset direction.

[0050] See Figure 7 and Figure 8As shown, in one embodiment of the second adjustment module 32, the second adjustment module 32 includes a lifting drive assembly 321, a rotation drive assembly 322, and at least two rotating blocks 323. The lifting drive assembly 321 is mounted on the frame 1. The rotation drive assembly 322 is mounted on the output end of the lifting drive assembly 321. The number of rotating blocks 323 and the number of adjustment stations 41 are the same, and they are arranged in a one-to-one correspondence. At least two rotating blocks 323 are slidably connected vertically to the output end of the rotation drive assembly 322 and are located above the corresponding adjustment station 41. The rotating blocks 323 are used to engage with the slots 81 of the dust cover 8. The lifting drive assembly 321 is used to drive the at least two rotating blocks 323 to move toward or away from the dust cover 8 of the corresponding adjustment station 41. The rotation drive assembly 322 is used to drive the at least two rotating blocks 323 to rotate vertically, and the rotation angle is a multiple of 180°. Thus, when adjusting the orientation of the slot 81 of the dust cover 8, firstly, the first adjustment module 31 limits the dust cover 8 to the corresponding adjustment position 41. Then, the lifting drive assembly 321 drives the rotating block 323 downward to insert into the slot 81 of the dust cover 8 in the corresponding adjustment position 41. At this time, if the corresponding slot 81 is not facing the preset direction, it means that the slot 81 and the rotating block 323 are misaligned. During the downward movement of the rotating block 323, it will abut against the locking arm 82 that makes up the slot 81 and cannot be inserted into the slot 81. Under the pressure of the locking arm 82, it slides upward, effectively preventing the rotating block 323 from damaging the dust cover 8. Then, the rotation drive assembly... The rotating block 323, driven by component 322, rotates vertically at any angle multiple of 180°. During this rotation, when the rotating block 323 is fully aligned with the slot 81, it slides downwards into the slot 81 under its own weight, causing the dust cover 8 to rotate accordingly. This ensures that all dust covers 8 on the assembly conveyor line 4 have their slots 81 facing a preset direction. Finally, the lifting drive component 321 drives the rotating block 323 upwards out of the slot 81, while the first adjustment module 31 releases the dust cover 8, allowing the subsequent assembly conveyor line 4 to transport the accurately positioned and oriented dust covers 8 to the assembly station for assembly. It can be seen that the second adjustment module 32, through the coordinated work of the lifting drive component 321, the rotation drive component 322, and the rotating block 323, can precisely adjust the orientation of the slots 81 of the dust cover 8, meeting assembly requirements and improving assembly efficiency and quality.

[0051] The aforementioned rotation angle is set to a multiple of 180° (the rotation angle can be a multiple of 180° such as 180° or 360°). This way, even if the slot 81 of the dust cover 8 is initially facing the preset direction, the rotating block 323 drives the dust cover 8 to rotate by a multiple of 180°, ensuring that the slot 81 is still facing the preset direction.

[0052] See Figure 7As shown, in one embodiment of the lifting drive assembly 321 and the rotary drive assembly 322, the lifting drive assembly 321 includes a mounting plate 3211 and a mounting plate drive assembly 3212. The mounting plate 3211 is slidably connected to the frame 1 vertically and is located above the feed end of the assembly conveyor line 4. The mounting plate drive assembly 3212 is mounted on the frame 1 by means of screwing or welding and is drively connected to the mounting plate 3211. The mounting plate drive assembly 3212 is used to drive the mounting plate 3211 to move towards or away from the assembly conveyor line 4. The rotary drive assembly 322 includes a gear shaft 3221, a rack 3222, and a rack drive member 3223. The gear shaft 3221 passes through and is rotatably connected to the mounting plate 3211 through a bearing. The number of gear shafts 3221 and rotating blocks 323 are the same, and they are arranged in a one-to-one correspondence. The rotating blocks 323 are slidably connected vertically to the bottom end of the corresponding gear shaft 3221. The rack 3222 is slidably connected to the mounting plate 3211 and meshes with the gear portion 3224 at the top of each gear shaft 3221. The rack drive 3223 is mounted on the mounting plate 3211 by means of screwing or welding and is connected to the rack 3222 in a transmission manner. The rack drive 3223 is used to drive the rack 3222 to slide along the conveying direction of the assembly conveyor line 4, so as to drive each gear shaft 3221 and its rotating block 323 to rotate by multiples of 180°. Thus, the lifting drive assembly 321 achieves the lifting and lowering of the mounting plate 3211 through the mounting plate drive assembly 3212, thereby driving all the rotating blocks 323 on the mounting plate 3211 to lift and lower synchronously to insert or remove from the slots 81 of several dust covers 8; the rotation drive assembly 322 drives the rack 3222 to slide through the rack drive component 3223, and the gear and rack 3222 transmission can drive all the rotating blocks 323 to rotate synchronously. The structure is ingenious, the transmission is stable, and the orientation of the slots 81 of several dust covers 8 can be precisely adjusted.

[0053] The aforementioned mounting plate drive assembly 3212 can use one or two telescopic cylinders or telescopic poles, etc., as linear drive mechanisms, and its output end is connected to the mounting plate 3211 by means of screwing or welding. The aforementioned rack drive assembly 3223 can use telescopic cylinders or telescopic poles, etc., as linear drive mechanisms, and its output end is connected to the rack 3222 by means of screwing or welding.

[0054] See Figure 7As shown, in one embodiment of the first adjustment module 31, the first adjustment module 31 includes a first limiting plate 311, a second limiting plate 312, and a limiting drive assembly 313. The first limiting plate 311 and the second limiting plate 312 are symmetrically located on both sides of the feed end of the assembly conveyor line 4. A feed channel 314 is formed between the first limiting plate 311 and the second limiting plate 312 for docking with the discharge end of the loading conveyor line 23. The feed channel 314 extends along the conveying direction of the assembly conveyor line 4 and is located above the assembly conveyor line 4. The feed channel 314 is used to accommodate a plurality of dust covers 8 with their openings facing upwards. A plurality of adjustment grooves 315 are formed between the first limiting plate 311, the second limiting plate 312, and the assembly conveyor line 4. The number of adjustment grooves 315 and adjustment stations 41 is the same, and they are arranged in a one-to-one correspondence. The adjustment grooves 315 are located below the feed channel 314 and are used to accommodate the dust covers 8 corresponding to the adjustment stations 41. The limit drive assembly 313 is mounted on the frame 1 by means of screwing or welding, and is connected to the first limit plate 311 and the second limit plate 312 in a transmission manner. The limit drive assembly 313 is used to drive the first limit plate 311 and the second limit plate 312 to move towards or away from each other, so as to reduce or expand the width of the feed channel 314 and the adjustment groove 315. In the initial state, the width of the feeding channel 314 is equal to the diameter of the dust cover 8. At this time, the first adjustment module 31 can receive several dust covers 8 with their openings facing upwards, which are conveyed by the feeding conveyor line 23 through the feeding channel 314. Then, the limit drive assembly 313 drives the first limit plate 311 and the second limit plate 312 to move in opposite directions, expanding the feeding channel 314 so that the dust cover 8 in the feeding channel 314 falls into the corresponding adjustment groove 315 under its own gravity. Next, the limit drive assembly 313 drives the first limit plate 311 and the second limit plate 312 to move towards each other, which can clamp and limit the dust cover 8 in the corresponding adjustment position 41, so that the dust cover 8 can only rotate vertically in the corresponding adjustment position 41, and cannot be displaced away from the adjustment position 41 in the vertical or any horizontal direction, ensuring the accuracy of the position of the dust cover 8 in the adjustment position 41, so that the second adjustment module 32 can rotate and adjust the orientation of the slot 81 of the dust cover 8. It can be seen that the first positioning module 31, through the cooperation of the first limiting plate 311, the second limiting plate 312 and the limiting drive component 313, can adjust the width of the feeding channel 314 and the adjusting groove 315 according to the size of the dust cover 8, thereby facilitating the entry and positioning of the dust cover 8.

[0055] The aforementioned limit drive assembly 313 can use existing clamping cylinders or motor-bidirectional lead screw nut bidirectional displacement mechanisms, and its two output ends are respectively connected to the first limit plate 311 and the second limit plate 312 by means of screwing or welding.

[0056] See Figure 7 and Figure 8As shown, based on the above embodiment, both the first limiting plate 311 and the second limiting plate 312 have U-shaped grooves 316 and at least two V-shaped recesses 317 on their opposing sides. The U-shaped grooves 316 extend along the conveying direction of the assembly conveyor line 4. The openings of the U-shaped grooves 316 of the first limiting plate 311 and the second limiting plate 312 are arranged opposite each other. A feeding channel 314 with openings at both ends is formed between the two U-shaped grooves 316. An adjustment groove 315 is formed between the V-shaped recesses 317 of the first limiting plate 311 and the second limiting plate 312. Thus, the arrangement of the U-shaped grooves 316 and the V-shaped recesses 317 makes the shape of the feeding channel 314 and the adjustment groove 315 more consistent with the shape of the dust cover 8, which can better accommodate and limit the dust cover 8, further improve the positioning accuracy of the dust cover 8, and provide a reliable guarantee for subsequent assembly. The V-shaped recess 317 can adapt to dust covers 8 of different diameters, enabling precise positioning of dust covers 8 of different diameters, thereby improving the versatility of the first adjustment module 31.

[0057] See Figure 7 As shown, based on the above embodiment, the steering mechanism 3 further includes a baffle module 33. The baffle module 33 includes two baffles 331 and two baffle drive members 332. The two baffles 331 are located at the two end openings of the feeding channel 314. The two baffle drive members 332 are mounted on the frame 1 by means of screwing or welding, and are respectively connected to the two baffles 331 in a transmission manner. The baffle drive members 332 are used to drive the baffles 331 to move toward or away from the feeding channel 314, so as to close or open the two end openings of the feeding channel 314. In this way, the baffle module 33 controls the displacement of the baffles 331 through the baffle drive members 332, realizes the closing and opening of the two end openings of the feeding channel 314, can control the timing and number of dust covers 8 entering, ensure the orderly arrangement of dust covers 8 in the feeding channel 314, avoid confusion, and affect the normal operation of subsequent steering adjustment work, thereby improving the working stability and reliability of the entire steering mechanism 3.

[0058] The aforementioned stop drive 332 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is connected to the stop 331 by means of screwing or welding.

[0059] See Figure 3 and Figure 8As shown, based on any of the above embodiments, the assembly conveyor line 4 has a bearing surface 42 for supporting the dust cover 8, and a plurality of adsorption holes 43 are evenly distributed on the bearing surface 42. The fully automatic lid and spoon assembly line also includes an adsorption mechanism 10. The adsorption mechanism 10 is provided on the assembly conveyor line 4 by means of screwing or welding, and communicates with the plurality of adsorption holes 43. The adsorption mechanism 10 is used to provide adsorption force to the adsorption holes 43 to position the dust cover 8 on the bearing surface 42. Thus, after all the dust covers 8 at adjustment stations 41 have been adjusted, the adsorption mechanism 10 is activated. Through the adsorption holes 43, the adjusted positions of all the dust covers 8 at adjustment stations 41 and the orientation of the slots 81 are fixed, effectively preventing the dust covers 8 from moving due to shaking or offset during transport. This allows the assembly conveyor line 4 to accurately transport the dust covers 8 to the corresponding spoon-pressing station 11 for spoon assembly. Furthermore, the adsorption holes 43 and the adsorption mechanism 10 work together to provide additional positioning force for the dust covers 8 at the spoon-pressing station 11, ensuring the dust covers 8 are more stably fixed on the station during assembly, further improving assembly accuracy and reliability. In addition, this adsorption positioning method does not damage the dust covers 8, guaranteeing product quality.

[0060] The aforementioned adsorption mechanism 10 can use existing air extraction equipment or negative pressure adsorption equipment.
