Description

Technical Field

[0001] The invention relates to the technical field of pallet production, and in particular to equipment and a method for producing aviation degradable pallets. Background Art

[0002] As an important part of modern logistics, the rapid development of air logistics has put forward higher requirements on pallets. As the key loading unit of air cargo transportation, air pallets need to meet the characteristics of lightweight, high strength and shock resistance. At the same time, the environmental problems caused by traditional plastic pallets due to their difficulty in degradation have attracted increasing attention. Therefore, degradable pallets have gradually become the first choice for environmentally friendly pallets due to their complete degradation, no toxic substances, and harmlessness to the soil.

[0003] The existing production process of pallets covers raw material processing, extrusion molding, vacuum forming, punching and perforating, automatic trimming and product quality inspection. Among them, the trimming and punching steps are aimed at improving the air permeability of the pallet and reducing its weight. After these two steps are completed, the pallet has a basic shape. At this time, in order to facilitate transportation, the processed pallets can be stacked and transported to the quality inspection department. However, in the existing process, the stacking and transportation of pallets depends on manual handling, which is not only inefficient, but also easily leads to uneven stacking problems. In particular, when pallets are stacked on each other, it becomes difficult to move the upper pallet due to increased friction, further increasing the difficulty of aligning the stack and the physical exertion. Based on this, the present invention purposely provides an aviation degradable pallet production device and method that can accurately stack punched pallets. Summary of the invention

[0004] The purpose of the present invention is to provide an aviation degradable pallet production device and method to solve the technical problems in the prior art in view of the shortcomings of the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions: An aviation degradable pallet production equipment, comprising: A processing seat, on which a clamping assembly for clamping and fixing a tray is provided, and a plurality of reserved holes are opened on the processing seat, and a plurality of first punching holes formed by punching assemblies are opened on the tray, and each first punching hole corresponds to a reserved hole, and the radius of the first punching hole is smaller than the radius of the reserved hole; A placement seat for stacking multiple pallets; A base, on which a moving frame is slidably mounted, the moving frame is driven by a first driving source to reciprocate between a processing seat and a placing seat, a lifting platform is slidably mounted on the moving frame, the lifting platform is driven by a second driving source to move up and down, and the bottom of the lifting platform is connected to a carrying plate through a fine-tuning component; The cam is connected to the support frame by a toothed structure, and the toothed structure is connected to the support frame by a toothed structure. The cam is connected to the support frame by a toothed structure, and the toothed structure is connected to the support frame by a toothed structure.

[0006] As a further solution of the present invention: the driving assembly includes an opening and a threaded rod, the opening is opened on the vertical rod, the ring is slidably installed in the opening, the threaded rod is rotatably installed in the vertical rod, and it is driven to rotate by an output source, and the threaded rod is threadedly connected to the ring.

[0007] As a further solution of the present invention: a vertical plate is slidably installed on the upper connecting rod and the lower connecting rod, and an arc block is connected to the side of the top of the vertical plate away from the vertical rod through a spring, and it is driven to move by a linkage assembly, and the pre-tightening force of the spring makes the arc block move away from the vertical plate, and when the driving assembly drives the ring to rise to the highest position, the upper connecting rod and the lower connecting rod rotate to drive the vertical plate to move through the linkage assembly, at this time the arc block abuts against the inner wall of the first punching hole and squeezes the spring, and when the driving assembly drives the ring to drop to the lowest position, the arc block is away from the inner wall of the first punching hole.

[0008] As a further solution of the present invention: when the driving assembly drives the ring to move, the dynamic distance is consistent with the radius of the first punching hole, and the upper connecting rod and the lower connecting rod rotate to drive the vertical plate to move through the linkage assembly. At this time, the arc block fits the inner wall of the first punching hole and the arc block is farthest from the vertical plate.

[0009] As a further solution of the present invention: the linkage assembly includes a first waist-shaped groove, a second waist-shaped groove, a first sliding rod and a second sliding rod, the first waist-shaped groove is opened on the upper connecting rod, the second waist-shaped groove is opened on the lower connecting rod, the first sliding rod is slidably installed in the first waist-shaped groove, and it is fixedly connected to the vertical plate, the second sliding rod is slidably installed in the second waist-shaped groove, and it is fixedly connected to the vertical plate.

[0010] As a further solution of the present invention: a scraper is fixedly connected to the outer circumferential surface of each vertical rod, and the scraper is located at the upper part. When the vertical rod descends, the scraper is slidably connected to the inner wall of the first punching hole.

[0011] As a further solution of the present invention: each vertical rod outer circular surface is fixedly connected with a conical platform, the radius of the conical platform decreases upward along its axial direction, and its bottom radius is smaller than the scraper radius. When the ring drops to the lowest position, the dynamic distance is smaller than the bottom radius of the conical platform.

[0012] A method for using an aviation degradable pallet production device, the method is applied to the aviation degradable pallet production device as described above, the method comprising the following steps: Step S1: placing a tray on a processing seat and clamping it with a clamping assembly, then punching the tray with a punching assembly to form a plurality of first punched holes on the tray; Step S2: The moving frame is moved to the top of the processing seat by the first driving source, and the driving assembly driving ring is raised to the highest position, at which time the three upper connecting rods and the three lower connecting rods are all formed into an umbrella shape, and then the lifting platform is driven down by the second driving source, at which time the vertical rod is lowered and enters the first punching hole; Step S3: The three lower connecting rods abut against the top edge of the first punching hole, thereby realizing automatic positioning, so that each vertical rod is coaxial with the first punching hole corresponding to each vertical rod, and then the driving assembly drives the collar to descend to the lowest position, and then the lifting platform continues to descend, at which time the vertical rod passes through the first punching hole and the reserved hole; Step S4: The driving assembly drives the collar to rise to the highest position. At this time, the three upper connecting rods abut against the edge of the bottom end of the first punching hole, and the clamping assembly releases the clamping of the tray. At this time, the movement of the vertical rod drives the tray to move synchronously; Step S5: Move the vertical rod to the position of stacking the trays, align the vertical rod with the first punching hole on the already stacked tray and insert it, at this time, the three lower connecting rods abut against the first punching hole on the already stacked tray, so that the first punching hole on the tray to be placed and the first punching hole on the already stacked tray are automatically positioned coaxially; Step S6: The driving assembly drives the collar to descend to the lowest position, at which time the trays on the three upper connecting rods gradually descend and finally complete the stacking.

[0013] Beneficial effects of the present invention: 1. In the present invention, the upper connecting rod and the lower connecting rod on the vertical rod are contracted and expanded, so that the vertical rod can be coaxial with the first punching hole on the pallet, so that the pallet is moved by the expanded upper connecting rod on the vertical rod, and then moved to the top of the stacked pallet, and then the vertical rod is coaxial with the first punching hole on the stacked pallet through the expanded lower connecting rod. At this time, the pallet on the vertical rod and the stacked pallet are completely aligned, and then the upper connecting rod and the lower connecting rod are contracted, and the pallet on the vertical rod gradually descends to finally complete the stacking, without the need for subsequent adjustment, thereby avoiding the problem of difficulty in moving the upper pallet due to static friction between the two pallets during stacking, and also improving the stacking efficiency, thereby accelerating the production efficiency; 2. In the present invention, when the collar is lowered to the lowest position, the arc block is away from the inner wall of the first punching hole, and the two are not in contact, thereby avoiding the generation of additional resistance that affects the vertical rod being inserted into the first punching hole and the vertical rod being moved out of the first punching hole. When the collar is raised to the highest position, the arc block abuts against the inner wall of the first punching hole and squeezes the spring, and the elastic deformation of the spring will strengthen the pressure of the arc block on the inner wall of the first punching hole. At this time, the vertical rod is not only supported by the upper connecting rod, but also by the pressure of the arc block on the inner wall of the first punching hole, as well as the static friction between the arc block and the first punching hole, so that the pallet can be further locked on the vertical rod, ensuring that the pallet can be stabilized on the vertical rod during the movement of the pallet; 3. In the present invention, when the vertical rod passes through the first punching hole and the reserved hole, the inner wall of the first punching hole can be scraped by the scraper, thereby cleaning the debris remaining on the inner wall of the first punching hole during punching.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 10 As shown, the present invention is a kind of aviation degradable pallet production equipment, comprising: A processing seat 16, on which a clamping assembly 18 for clamping and fixing a tray 20 is provided, and a plurality of reserved holes 17 are opened on the processing seat 16, and a plurality of first punching holes 21 formed by punching assemblies are opened on the tray 20, and each first punching hole 21 corresponds to a reserved hole 17, and the radius of the first punching hole 21 is smaller than the radius of the reserved hole 17; A placement seat 19 for stacking a plurality of trays 20; A base 1, on which a moving frame 2 is slidably mounted, the moving frame 2 is driven by a first driving source to reciprocate between a processing seat 16 and a placement seat 19, a lifting platform 3 is slidably mounted on the moving frame 2, the lifting platform 3 is driven by a second driving source to move up and down, and the bottom of the lifting platform 3 is connected to a carrying plate 4 through a fine-tuning component; The vertical rod 5 has a radius smaller than the radius of the first punching hole 21. A plurality of vertical rods 5 are fixedly mounted on the carrier plate 4, and each vertical rod 5 corresponds to a tray 20. A fixing ring 22 is fixedly mounted on the outer circumference of the vertical rod 5, and a sleeve 6 is sleeved on the outer circumference of the vertical rod 5. The sleeve 6 is located below the fixing ring 22. The sleeve 6 is slidably connected to the vertical rod 5, and is driven by the driving assembly 9 to be lifted and lowered. Three upper connecting rods 7 are rotatably mounted on the fixing ring 22. The three upper connecting rods 7 are arranged circumferentially, and one end of each upper connecting rod 7 away from the fixing ring 22 is rotatable. The lower connecting rod 8 is dynamically connected, and the length of the lower connecting rod 8 and the upper connecting rod 7 are the same. The lower connecting rod 8 is rotatably connected to the collar 6. The distance between the rotating joint of the upper connecting rod 7 and the lower connecting rod 8 and the axis of the vertical rod 5 is the dynamic distance. The dynamic distance increases as the collar 6 rises. When the driving component 9 drives the collar 6 to descend to the lowest position, the dynamic distance is smaller than the radius of the first punching hole 21. When the driving component 9 drives the collar 6 to rise to the highest position, the dynamic distance is greater than the radius of the first punching hole 21, but the dynamic distance is smaller than the radius of the reserved hole 17.

[0019] In one case of this embodiment, the fine-tuning component can be set as an electric two-axis moving module, which are all existing technologies and are not disclosed in detail here, which does not affect the integrity of the solution. The first driving source and the second driving source can both use electric telescopic rods and reciprocating cylinder components, and other mechanisms that can achieve linear reciprocating motion can also be used. This embodiment is not specifically limited here. It should be noted that the punching assembly and clamping assembly 18 described in the present invention are all existing technologies. The punching assembly includes a punch, a guide column, a driving member, etc., and the clamping assembly 18 includes a driving member, a splint, etc. The present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0020] The working principle of the present invention is as follows: first, the pallet 20 is produced, and the specific steps include: first, EPLA sheet and EPLA core material are used as raw materials to ensure that their quality meets the production requirements, and then the EPLA core material is heated to plasticize it for subsequent molding processing, and then the plasticized EPLA material is injected into the mold, and the pallet 20 is shaped by the shape and size of the mold. After the EPLA material in the mold is cooled and stabilized, the mold is opened, and the pallet 20 can be taken out, and then the heated and softened EPLA sheet is coated on the formed pallet 20 to complete the production of the pallet 20; then the pallet 20 is placed on the processing seat 16 and clamped and fixed by the clamping assembly 18, and then the punching assembly is used to process and form a plurality of first punching holes 21 on the pallet 20. At this time, the first punching hole 21 and the reserved hole 17 are coaxially arranged, and then the lifting platform 3 is moved by the cooperation of the first driving source and the second driving source, so that the vertical rod 5 is initially aligned with the first punching hole 21, and then the driving assembly 9 drives the collar 6 to rise to the highest position, and at this time the upper connecting rod 7 and the lower connecting rod 8 rotate and unfold, so as to Figure 3 The contraction state is transformed into Figure 6 The vertical rod 5 is in the expanded state, at this time, it is lowered and inserted into the first punching hole 21. Since the upper connecting rod 7 and the lower connecting rod 8 form an umbrella shape after being unfolded, and the distance between the rotation joint of the upper connecting rod 7 and the lower connecting rod 8 and the axis of the vertical rod 5 is a dynamic distance, Figure 6 The dynamic distance in is greater than the radius 21, so when the vertical rod 5 descends, the lower connecting rod 8 will abut against the top edge of the first punching hole 21, and the umbrella shape formed by the circumferential arrangement of the three lower connecting rods 8 can guide the vertical rod 5 to gradually move to a position coaxial with the first punching hole 21. This process is completed by the fine-tuning component set between the supporting plate 4 and the lifting platform 3. The specific process is to unlock the fine-tuning component, and then the three lower connecting rods 8 abut against the edge of the first punching hole 21 during the descent of the vertical rod 5. If any side deviates too much, the lower connecting rod 8 on this side will slide and displace with the top of the first punching hole 21, and the supporting plate 4 will move accordingly on the fine-tuning component until the three lower connecting rods 8 abut against the edge of the first punching hole 21. At this time, the positioning of the vertical rod 5 and the first punching hole 21 is completed, and then the fine-tuning component is locked; Then the upper connecting rod 7 and the lower connecting rod 8 return to Figure 3 The vertical rod 5 is in the contracted state, at which time it can pass through the first punching hole 21 and the reserved hole 17 when it descends. Figure 7 As shown in the example, then Figure 8As shown, the upper connecting rod 7 and the lower connecting rod 8 are converted into an expanded state in the reserved hole 17, and then the vertical rod 5 rises to allow the three upper connecting rods 7 to abut against the bottom edge of the first punching hole 21, so that the tray 20 moves synchronously with the vertical rod 5. At this time, the tray 20 can be moved to the placement seat 19 where multiple trays 20 are stacked, and then the fine-tuning component is unlocked, so that the vertical rod 5 is lowered and inserted into the first punching hole 21 of the tray 20 stacked below. Through the cooperation of the three expanded lower connecting rods 8 and the fine-tuning component, the axis of the first punching hole 21 of the tray 20 on the vertical rod 5 and the axis of the first punching hole 21 of the tray 20 below can be gradually overlapped, and finally as shown in FIG. Fig. 9 As shown, the upper connecting rod 7 and the lower connecting rod 8 are then retracted, and the tray 20 on the vertical rod 5 will fall and complete the stacking, as shown in FIG. Fig.10 shown.

[0021] like Figure 3 As shown, as a preferred embodiment of the present invention, the driving assembly 9 includes an opening 901 and a threaded rod 902, the opening 901 is opened on the vertical rod 5, the collar 6 is slidably installed in the opening 901, the threaded rod 902 is rotatably installed in the vertical rod 5, and it is driven to rotate by an output source, and the threaded rod 902 is threadedly connected to the collar 6.

[0022] In one case of this embodiment, the output source may be a servo motor or a servo motor, or other mechanisms capable of achieving rotational motion, which is not specifically limited in this embodiment.

[0023] In actual application of this embodiment, the limitation of the ring 6 being slidably installed in the opening 901 can avoid the rotational movement of the ring 6 on the vertical rod 5, so that it can only be raised and lowered, and the output source drives the threaded rod 902 to rotate, and the threaded rod 902 and the opening 901 are threadedly connected, and the opening 901 can be raised and lowered by the rotation of the threaded rod 902, thereby driving the upper connecting rod 7 and the lower connecting rod 8 to switch between the expanded state and the contracted state.

[0024] like Figure 1-Figure 10 As shown, as a preferred embodiment of the present invention, a vertical plate 10 is slidably installed on the upper connecting rod 7 and the lower connecting rod 8, and the top of the vertical plate 10 is connected to an arc block 11 through a spring 12 on a side away from the vertical rod 5, and it is driven to move by a linkage assembly 13. The preload force of the spring 12 makes the arc block 11 away from the vertical plate 10, and when the driving assembly 9 drives the ring 6 to rise to the highest position, the upper connecting rod 7 and the lower connecting rod 8 rotate to drive the vertical plate 10 to move through the linkage assembly 13. At this time, the arc block 11 abuts against the inner wall of the first punching hole 21 and squeezes the spring 12. When the driving assembly 9 drives the ring 6 to drop to the lowest position, the arc block 11 is away from the inner wall of the first punching hole 21.

[0025] In practical application of this embodiment, the relationship between the arc block 11 and the inner wall of the first punching hole 21 can be changed by moving the vertical plate 10. Figure 7 As shown, when the collar 6 drops to the lowest position, the arc block 11 is away from the inner wall of the first punching hole 21, and the two are not in contact, thereby avoiding the generation of additional resistance to affect the vertical rod 5 to be inserted into the first punching hole 21 and the vertical rod 5 to be moved out of the first punching hole 21. Figure 8 As shown, when the ring 6 rises to the highest position, the arc block 11 abuts against the inner wall of the first punching hole 21 and squeezes the spring 12, and the elastic deformation of the spring 12 will strengthen the pressure of the arc block 11 on the inner wall of the first punching hole 21. At this time, the vertical rod 5 is not only supported by the upper connecting rod 7, but also by the pressure of the arc block 11 on the inner wall of the first punching hole 21, as well as the static friction between the arc block 11 and the first punching hole 21, so that the tray 20 can be further locked on the vertical rod 5 to ensure that the tray 20 can be stabilized on the vertical rod 5 during the movement of the tray 20.

[0026] like Figure 1-Figure 10 As shown, as a preferred embodiment of the present invention, when the driving assembly 9 drives the ring 6 to move, the dynamic distance is consistent with the radius of the first punching hole 21, and the upper connecting rod 7 and the lower connecting rod 8 rotate to drive the vertical plate 10 to move through the linkage assembly 13. At this time, the arc block 11 fits the inner wall of the first punching hole 21 and the arc block 11 is farthest from the vertical plate 10.

[0027] In actual application of this embodiment, the arc block 11 is farthest from the vertical plate 10, which means that the arc block 11 has no elastic deformation. Therefore, at this time, the arc block 11 does not apply a lateral force to the first punching hole 21, and the arc block 11 fits the inner wall of the first punching hole 21, which means that there is static friction between the two. When the driving component 9 drives the collar 6 to move, the dynamic distance is consistent with the radius of the first punching hole 21. This means that only in this state, the lateral force applied by the arc block 11 to the first punching hole 21 will disappear, which results in the upper connecting rod 7 and the lower connecting rod 8 gradually moving from the expanded state to the contracted state. When the contraction state is converted, the pallet 20 will be continuously subjected to the lateral force exerted by the arc block 11 on the first punching hole 21 for a period of time, which will cause the pallet 20 to fail to descend along the contracted plate surface of the upper connecting rod 7 in time, resulting in hysteresis. After the lateral force between the arc block 11 and the first punching hole 21 suddenly disappears, the pallet 20 will suddenly drop under the action of gravity, which may cause it to hit the pallet 20 stacked below. At this time, the friction between the arc block 11 and the inner wall of the first punching hole 21 will slow down the descending speed of the pallet 20, thereby reducing the impact of the above-mentioned impact on the pallet 20 stacked below.

[0028] like Figure 3-Figure 5As shown, as a preferred embodiment of the present invention, the linkage assembly 13 includes a first waist-shaped groove 1301, a second waist-shaped groove 1302, a first slide bar 1303 and a second slide bar 1304, the first waist-shaped groove 1301 is opened on the upper connecting rod 7, the second waist-shaped groove 1302 is opened on the lower connecting rod 8, the first slide bar 1303 is slidably installed in the first waist-shaped groove 1301, and it is fixedly connected to the vertical plate 10, the second slide bar 1304 is slidably installed in the second waist-shaped groove 1302, and it is fixedly connected to the vertical plate 10.

[0029] In actual application of this embodiment, since the first sliding rod 1303 and the second sliding rod 1304 are both fixed on the vertical plate 10, the distance between the two is constant, and when the upper connecting rod 7 and the lower connecting rod 8 are contracted and expanded, the distance between the first waist-shaped groove 1301 and the second waist-shaped groove 1302 is dynamically changed. Figure 4 In the embodiment, the vertical rod 5 and the collar 6 are farthest apart. At this time, the upper connecting rod 7 and the lower connecting rod 8 are in a contracted state, that is, the angle between the first waist-shaped groove 1301 and the second waist-shaped groove 1302 is large, so the first sliding rod 1303 and the second sliding rod 1304 with a constant distance will slide to a position close to the vertical rod 5. Figure 6 In the embodiment, the vertical rod 5 and the collar 6 are closest to each other, and the upper connecting rod 7 and the lower connecting rod 8 are in an expanded state, that is, the angle between the first waist-shaped groove 1301 and the second waist-shaped groove 1302 is small, so the first sliding rod 1303 and the second sliding rod 1304 with a constant distance will slide to a position away from the vertical rod 5. In this way, the distance between the vertical plate 10 and the inner wall of the first punching hole 21 can be automatically adjusted by the contraction and expansion of the upper connecting rod 7 and the lower connecting rod 8, thereby adjusting the contact relationship between the first punching hole 21 and the arc block 11, so as to achieve the following effects, such as stabilizing the tray 20 on the vertical rod 5 and avoiding the tray 20 from impacting the things already stacked below when stacking.

[0030] like Figure 1-Figure 10 As shown, as a preferred embodiment of the present invention, a scraper 15 is fixedly connected to the outer circumferential surface of each vertical rod 5, and the scraper 15 is located above 24. When the vertical rod 5 descends, the scraper 15 is slidably connected to the inner wall of the first punching hole 21.

[0031] In actual application of this embodiment, when the vertical rod 5 passes through the first punching hole 21 and the reserved hole 17, the scraper 15 can scrape the inner wall of the first punching hole 21 once, so as to clean the debris remaining on the inner wall of the first punching hole 21 during punching.

[0032] like Figure 1-Figure 10As shown, as a preferred embodiment of the present invention, the outer circumferential surface of each vertical rod 5 is fixedly connected to a conical platform 14, the radius of the conical platform 14 decreases upward along its axial direction, and the bottom radius is smaller than the radius of the scraper 15. When the ring 6 drops to the lowest position, the dynamic distance is smaller than the bottom radius of the conical platform 14.

[0033] In actual application of this embodiment, since the scraper 15 scrapes the debris on the inner wall of the first punching hole 21 and it falls on the upper connecting rod 7 and the lower connecting rod 8 below, the conical platform 14 is set so that the debris will fall on the inclined surface of the conical platform 14 when it is scraped off, and slide down along the inclined surface and slide down from the bottom edge of the conical platform 14. At this time, the upper connecting rod 7 and the lower connecting rod 8 are in a retracted state, so that the falling trajectory of the debris avoids the upper connecting rod 7 and the lower connecting rod 8, and is directly discharged from the first punching hole 21 and the reserved hole 17. This ensures that when cleaning the debris remaining in the punching hole, it will not fall into the components below, causing the problem of debris getting stuck in the gaps between the components.

[0034] See also Figure 1-Figure 10 As shown, the present invention is a method for using an aviation degradable pallet production device, the method is applied to an aviation degradable pallet production device as described in the above embodiment, and the method comprises the following steps: Step S1: placing a tray 20 on the processing seat 16 and clamping and fixing it by the clamping assembly 18, and then punching the tray 20 by the punching assembly to form a plurality of first punching holes 21 on the tray 20; Step S2: The moving frame 2 is moved to the top of the processing seat 16 by the first driving source, and the driving assembly 9 drives the collar 6 to rise to the highest position. At this time, the three upper connecting rods 7 and the three lower connecting rods 8 form an umbrella shape. Then, the lifting platform 3 is driven down by the second driving source. At this time, the vertical rod 5 descends and enters the first punching hole 21; Step S3: The three lower connecting rods 8 abut against the top edge of the first punching hole 21, thereby achieving automatic positioning, so that each vertical rod 5 is coaxial with the first punching hole 21 corresponding to each vertical rod 5, and then the driving assembly 9 drives the collar 6 to descend to the lowest position, and then the lifting platform 3 continues to descend, and at this time the vertical rod 5 passes through the first punching hole 21 and the reserved hole 17; Step S4: The driving assembly 9 drives the collar 6 to rise to the highest position. At this time, the three upper connecting rods 7 abut against the edge of the bottom end of the first punching hole 21, and the clamping assembly 18 releases the clamping of the tray 20. At this time, the movement of the vertical rod 5 drives the tray 20 to move synchronously; Step S5: Move the vertical rod 5 to the position of stacking the trays 20, align the vertical rod 5 with the first punching hole 21 on the already stacked tray 20 and insert it, at this time, the three lower connecting rods 8 abut against the first punching hole 21 on the already stacked tray 20, so that the first punching hole 21 on the tray 20 to be placed and the first punching hole 21 on the already stacked tray 20 are automatically positioned coaxially; Step S6: The driving assembly 9 drives the collar 6 to descend to the lowest position, at which time the trays 20 on the three upper connecting rods 7 gradually descend, and finally the stacking is completed.
