Description

Technical Field

[0001] The invention belongs to the technical field of product packaging, and in particular relates to a framing process based on the alignment of material frames and the staggered stacking of screens and partitions. Background Art

[0002] At present, the processing of LCD screens inevitably involves the final framing process. In order to achieve the stacking and framing of multiple screens, a partition is used to separate each LCD screen after it is installed, so that each adjacent LCD screen is separated by a partition.

[0003] However, the following technical defects are prone to occur in the process of automated framing of LCD screens:

[0004] 1. The material frame is basically transferred and replaced by an endless conveyor belt. Therefore, the position and angle of the material frame are difficult to control accurately. Once the frame is offset, there is a possibility of screen collision or partition wrinkling during the installation of the screen or partition. In addition, it is impossible to effectively ensure that the screens are aligned in the stacked frame.

[0005] 2. Based on the framing station, the material frame preparation, screen transfer, partition absorption and unloading after packing are arranged. If conventional flow-line operation is adopted, the operation line will inevitably be long, so the equipment requires a large installation space.

[0006] 3. The absorption of the partitions used is basically done by negative pressure adsorption from the middle, and the partitions are layered through the comb teeth in the end, and the automatic feeding of each partition is completed in the gradual lifting. However, based on the framing of screens and partitions of different sizes, once the area of the partition is large, it is easy to cause the edges of the partition to be layered and fit in the middle. Therefore, in actual operation, multiple partitions often form a partition, which not only occupies the storage space of the material frame, but also because the friction between the partitions and the friction between the partitions and the screen are different, it is easy to cause the screen to shift or collide due to unstable stacking. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a new framing process based on the alignment of material frames and the staggered stacking of screens and partitions.

[0008] To achieve the above object, the present invention adopts the following scheme:

[0009] A framing process based on the alignment of material frames and the staggered stacking of screens and partitions, wherein the framing machine used includes a framing station, a feeding unit, a material frame preparation unit arranged side by side with the feeding unit and in the opposite direction of transmission, a screen loading unit, and a partition loading unit, and comprises the following steps:

[0010] S1. Material frame alignment, transfer and replacement

[0011] After the material frame enters the feeding position of the material preparation station, it is first aligned and corrected. Then, based on the transfer of the carrier at the material preparation station, the corrected material frame is moved forward with the corrected posture to complete the automatic filling of the material frame in the material discharge position of the material preparation station. At the same time, the material frame is taken out from the material discharge position and is horizontally loaded to the framing station with the corrected posture.

[0012] S2. Screen framing

[0013] The screen robot is used to transfer the screen to the framing station by suction, and then the screen is aligned and placed into the material frame;

[0014] S3, partition frame

[0015] The stacked partition racks are first placed on the material table, and with one side of the material table as the reference plane, a plurality of fences moving along the length and width of the material table are used to fit the side edges of the stacked partitions and align the partitions, and the plurality of fences and the material table constitute a stacking area at the bottom and a layer separation area at the top, wherein the side surfaces constituting the layer separation area are toothed groove surfaces extending horizontally from top to bottom; secondly, the material table is lifted to move the partitions in the stacking area to the layer separation area, and the two layers of partitions are relatively rubbed apart based on the obstacles swept by the brushes between the layer separation area and the stacking area, so that the middle part of the single-layer partition is arched and deformed upward, and wedged into the aligned tooth grooves from the side, and at the same time, the partitions are gradually moved upward to the upper tooth grooves, and the airflow in the length and width direction of the partition formed by the tooth groove surface eliminates static electricity and assists in stratification, so that the tooth groove surfaces of the layer separation area are filled in sequence; finally, the partition robot adopts negative pressure to adsorb the middle part of the partition on the top layer of the layer separation area, rotates and transfers it, and lays it on the surface of the screen to complete the framing, and at the same time, the tooth grooves on the top layer are filled;

[0016] S4, stacking frame and unloading

[0017] Repeat steps S2 and S3 in sequence. After the stacking and framing are completed, the material frame is transferred from the framing station by the material feeding unit.

[0018] Preferably, in step S1, the alignment correction is performed based on one end of the material frame and the center line of the material frame in the longitudinal direction is aligned with the center line of the feeding position by adjusting the motion of the two sides. Based on the position calibration formed by the feeding position, each material frame is passed forward after being corrected.

[0019] According to a specific embodiment and preferred aspect of the present invention, a material preparation station includes a material preparation base, two carrier plates installed on the material preparation base and spaced apart, wherein the top surfaces of the two carrier plates are flush, and multiple material preparation stations are formed in the length direction of the two carrier plates, wherein the multiple material preparation stations include at least a material inlet position and a material outlet position, and the carrier can move between the two carrier plates to transfer the material frame. The carrier can transfer the corrected material frame relatively stably to the station, thereby reducing the deviation of the material frame caused by the material frame loading process.

[0020] Preferably, the movement of the carrier includes lifting movement in the up and down directions and lateral movement in the front and back directions, wherein each material frame is transferred from the input position to the output position, and the transfer path is a circular transfer path upward, forward, downward and backward, and the carrier transfers the material frames on each preparation station forward one by one along the circular transfer path to fill the position.

[0021] According to another specific embodiment and preferred aspect of the present invention, the alignment mechanism comprises L-shaped alignment arms slidably mounted on the carrier plate, and an alignment force element that drives the L-shaped alignment arms toward or away from each other. The vertical portions of the L-shaped alignment arms extend along the length of the carrier plate, while the horizontal portions extend along the width of the carrier plate. The horizontal portions of the two L-shaped alignment arms are aligned to form an end reference. The relative motion of the two L-shaped arms achieves alignment of the length and width of the material frame, optimizing the alignment structure and ensuring relatively consistent positioning on the carrier plate.

[0022] In some specific embodiments, alignment rollers are provided on the horizontal portions of the L-shaped alignment arms. The axes of the alignment rollers extend vertically, with a portion of the alignment rollers positioned above the L-shaped region formed by the L-shaped alignment arms. As the two L-shaped alignment arms move toward each other, the alignment rollers contact the material frame, causing the material frame to be corrected using the end faces contacted by the alignment rollers as a reference. Using rollers that move synchronously with the L-shaped alignment arms not only forms a reference end face during the correction process, but also facilitates rotational correction of the material frame due to the contact of the rollers, thereby improving correction efficiency and accuracy.

[0023] According to another specific embodiment and preferred aspect of the present invention, in step S3, adjustment slots extending in both the length and width directions are formed on the material table. Each of the enclosure rods extends vertically through the adjustment slots, and the areas formed by the enclosure rods are adjusted to match the size of the partitions. The adjustable enclosure rods allow for placement of partitions of varying sizes, and the adjustment of the enclosure rods further aligns the stacked partitions, reducing the probability of misaligned stacking of the partitions.

[0024] Preferably, one side of the material platform serves as a support grid, and multiple fences are arranged in corresponding adjustment slots based on the support grid. The fences, the support grid, and the material platform form a stacking area and a layering area. Based on the support grid, the movement of the fences aligns the shelves, facilitating the gradual feeding of the shelves.

[0025] In some specific embodiments, each fence post comprises a main body and a layering module located on top of the main body. The main body, backrest plate, and material platform form a stacking area, while the layering module and backrest plate form a layer separation area, with the cross-sectional area of the layer separation area being smaller than that of the stacking area. In this manner, aligned stacking is achieved in the large stacking area, while the arched deformation layering formed by the smaller layer separation area facilitates the piece-by-piece feeding of the separators.

[0026] Preferably, each layered module forms a horizontally extending, vertically aligned toothed surface on the side surface of the layered compartment. The horizontally aligned toothed surfaces and the grid plates of each layered module form a single compartment. The partitions are embedded into the compartments from the sides relative to the layers. By sequentially arranging multiple compartments, the partitions are better layered.

[0027] In some embodiments, each rod body is provided with an air pipe on its back, and each toothed surface is formed with at least one exhaust hole connected to the air pipe. The exhaust holes simultaneously eject deionized gas from two or three sides. The ejection of deionized gas not only eliminates static electricity between the stacked separators but also facilitates delamination between the upper and lower separators during gas flow.

[0028] In some embodiments, a brush is located between the two rod bodies on one side, corresponding to the transition zone between the layer compartment and the stacking area. The brush's primary function is to prevent two separators from entering the layer compartment simultaneously when feeding from the stacking area to the layer compartment, thereby maintaining a single separator in each individual compartment and reducing the probability of two separators being attracted.

[0029] According to another specific embodiment and preferred aspect of the present invention, during the separator framing in step S3, after the top separator is adsorbed, the separator is shaken up and down to flatten the separator. That is, when adsorbing a single separator, the shaking is used to avoid adsorbing two separators. The shaking process also helps restore the separator to its natural state, preventing wrinkles in the separator during framing that could affect the stability of the stacked framing.

[0030] Furthermore, the feed unit and the frame preparation unit share the same structure and are arranged side by side. The framing stations are positioned one-to-one with the feed units. Multiple lines are used for framing and unloading, reducing the frequency of material collection. Furthermore, if one line fails, the others can continue framing normally, increasing framing efficiency.

[0031] Preferably, the shelf loading unit is aligned side by side with the framing station, with the shelf loading unit and the discharge station located on opposite sides of the framing station. The screen loading unit is located on the same side as the shelf loading unit, framing station, and discharge station. This positioning layout makes the structure more compact and facilitates framing operations.

[0032] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0033] In the framing process of existing LCD screens, the material frame is basically transferred and replaced by an annular conveyor belt. Therefore, the position and angle of the material frame transfer are difficult to control accurately. Once the offset occurs, there is not only the probability of screen bumping or partition wrinkling during the installation of the screen or partition, but also the stacking framing that each screen is aligned up and down cannot be effectively met. Then, the material frame preparation, screen transfer, partition suction and unloading after packaging are arranged based on the framing station. If conventional flow-line operation is adopted, the operation line will inevitably be long, so the installation space required for the equipment is large. At the same time, the absorption of the partition adopted is basically from the negative pressure adsorption in the middle, and at the same time through the end The comb teeth inside the frame are used to layer the partitions, and automatic feeding of each partition is completed in the gradual lifting. However, in terms of framing screens and partitions of different sizes, once the area of the partition is large, it is easy to cause the edges of the partitions to be layered and fit in the middle. Therefore, in actual operation, multiple partitions often form a partition, which not only occupies the storage space of the material frame, but also because the friction between the partitions and the friction between the partitions and the screen are different, it is easy to cause the screen to shift or collide due to unstable stacking, etc. The overall design of the present invention is based on the framing process of positioning the material frame, staggered stacking of the screen and the partition, which cleverly solves the various existing deficiencies.After adopting the framing process, first, the material frame is aligned, transferred and filled. After the material frame enters the feeding position of the material preparation station, it is first aligned and corrected. Then, based on the transfer of the carrier at the material preparation station, the corrected material frame is moved forward with the correction posture to complete the automatic filling of the material frame in the material discharge position of the material preparation station. At the same time, the material frame is taken out from the material discharge position and is horizontally loaded to the framing station with the correction posture; secondly, the screen is adsorbed and transferred to the framing station based on the screen robot, and the screen is aligned and placed in the material frame; then the partition is layered first, and then the partition is framed. When the partition is layered, the stacked partition frames are placed on the It is placed on the material table, and based on the movement of multiple fences, the side edges of the stacked partitions are fitted to align the partitions, and the multiple fences and the material table constitute a stacking area at the bottom and a layer separation area at the top; then the material table is lifted upward to move the partitions in the stacking area to the layer separation area, and at the same time, the partitions in the layer separation area are first rubbed apart by the brushes on the side so that each partition is wedged into the aligned tooth grooves from the side, and the middle of each partition is arched upward to form partition layers. When the partitions are framed, when one partition is completed in the stacking area, the partitions in the layer separation area are gradually moved upward, and based on the airflow blown out from the tooth grooves, Between each two adjacent partitions, static electricity is eliminated and stratification is assisted. At the same time, the partition robot is adsorbed from the middle of the top partition, and the side of the top partition is separated from the top tooth groove and restored to a horizontal state. Then the partition is transferred and laid on the surface of the screen; finally, the partition framing and partition framing are repeated to complete the interval stacking framing of the screen and partitions, and the material frame is unloaded and removed from the framing station by the feeding unit. Therefore, on the one hand, the present invention is based on the feeding correction of each material frame, and keeps the corrected posture forward and reprinted, so that the material frame is accurately located at the framing station, reducing the screen bumping or The probability of partition wrinkles; on the other hand, based on the division of the stacking area and the layer separation area, without being restricted by the size of the partition, the stacking area is used to add partitions to the layer separation area, and the two layers of partitions are rubbed apart by the obstruction formed by the brush, so that each partition is in an arched state and embedded in each tooth groove, and as the material table is lifted, the partition is always kept in a layered state and filled upward. At the same time, the multi-directional airflow blowing during the upward filling process not only eliminates static electricity, but also can further assist in stratification, so that each partition can be adsorbed and taken out with zero error, and avoids the phenomenon of multiple layers of partitions being adsorbed and framed at one time.

[0055] like Figures 1 to 10 As shown, the framing machine of this embodiment includes a framing station 1, a feeding unit 2 connected to the framing station 1, a material frame preparation unit 3 arranged side by side with the feeding unit 2, a screen loading unit 4 and a partition loading unit 5.

[0056] Specifically, the material frame preparation unit 3 and the feeding unit 2 have the same structure, wherein the material frame preparation unit 3 includes a material preparation seat 30, two carrier plates 31 installed on the material preparation seat 30 and spaced apart, an alignment mechanism 32, a carrier 33, a carrier power device 34 and a material frame transverse movement robot 35, wherein a gap is formed between the two carrier plates 31, and a plurality of material preparation stations are divided in sequence in the length direction. At the same time, the plurality of material preparation stations include a feeding position, a temporary storage position and a discharging position. The alignment mechanism 32 is arranged at the feeding position, and the discharging position is aligned with the framing station 1. The carrier 33 can move between the material preparation stations to transfer the material frame X, and the material frame transverse movement robot 35 moves the material frame at the discharging position to the framing station 1 for replacement and transfer.

[0057] In some specific embodiments, the alignment mechanism 32 includes L-shaped alignment arms 320 slidably mounted on the carrier plate 31 and an alignment actuator 321 that drives the L-shaped alignment arms 320 toward or away from each other. The vertical portions of the L-shaped alignment arms 320 extend along the length of the carrier plate 31, while the horizontal portions extend along the width of the carrier plate 31. The horizontal portions of the two L-shaped alignment arms 320 are aligned to form an end reference. The relative motion of the two L-shaped arms achieves alignment in both the length and width of the material frame, optimizing the alignment structure and ensuring consistent positioning on the carrier plate. In this example, alignment rollers 322 are provided on the horizontal portions of the L-shaped alignment arms 320. The axes of the alignment rollers 322 extend vertically, with portions of the alignment rollers 322 positioned above the L-shaped region formed by the L-shaped alignment arms 320. As the two L-shaped alignment arms 320 move toward each other, the alignment rollers 322 contact the material frame X, allowing the material frame X to be aligned with the end faces contacted by the alignment rollers 322 as a reference. Using rollers that move synchronously with the L-shaped alignment arms 320 not only forms a reference end face during the alignment process, but also facilitates rotational correction of the material frame due to the contact of the rollers, thereby improving alignment efficiency and accuracy. The carrier plate 31 is of segmented type, that is, each material preparation station is composed of two carrier plates 31 and a docking frame, or the carrier plate 31 is of integral type, and is divided into areas along the entire length direction of the carrier plate 31 to form multiple material preparation stations; the movement of the platform 33 includes lifting movement in the up and down directions and lateral movement in the front and back directions, wherein each material frame X is transferred from the material input position to the material output position, and the transfer path is an upward, forward, downward and backward circular transfer path, and the platform 33 transfers the material frames on each material preparation station forward one by one along the circular transfer path to fill the position. The carrier power device 34 includes a shifting power part in the front and rear directions and a lifting power part in the up and down directions. The material frame transverse movement robot 35 includes a truss 350, a slide rail 351 fixed on the truss 350 and consistent with the extension direction of the truss, a slide seat 352 slidably installed on the slide rail 351, a shift seat 353 installed on the slide seat 352 for up and down sliding adjustment, and a clamping arm 354 installed on the shift seat 353 and capable of relative sliding adjustment along the length direction of the slide rail 351. The clamping arm 354 clamps the opposite sides of the material frame X, and then the material frame X is replaced based on the up and down and transverse movement.

[0058] The feeding unit 2 is arranged side by side with the material frame preparation unit structure 3; the framing station 1 is arranged in a one-to-one correspondence with the feeding unit 2. Multiple lines are used for framing and unloading to reduce the frequency of users receiving materials, and when one of the lines fails, the other lines can still work normally for framing, which can increase the framing efficiency. In this example, there are two framing stations 1, and the two framing stations 1, the discharge position, and the partition feeding unit 5 are aligned side by side, and the discharge position and the partition feeding unit 5 are respectively located on the opposite outsides of the two framing stations 1; at the same time, the screen feeding unit 4 is located on the same side of the partition feeding unit 5, the framing station 1 and the discharge position. Based on the position layout, the structure is more compact and convenient for framing operations.

[0059] The screen loading unit 4 adopts an assembly line operation (the position indicated by the arrow in the accompanying drawing is the structural position of the layout of the screen loading unit 4, which forms a screen transmission direction perpendicular to the material frame output direction), and adopts a screen manipulator to adsorb and transfer on the transmission line, which is a conventional design (omitted, but it is also clear and feasible), wherein the structure of the screen manipulator is similar to the partition manipulator of the partition loading unit 5, and both adopt negative pressure adsorption for transfer; as for the screen assembly line transmission, a conventional ring conveyor belt can be used, or a structure of a material frame preparation unit 3 and a feeding unit 2 similar to that of the present application can be used.

[0060] The partition loading unit 5 includes a frame 50, a guard plate 51 located on one side of the frame 50 and extending up and down, a material platform 52 that moves up and down based on the guard plate 51, and a plurality of guard rods 53 that pass through the material platform 52 and can be slidably installed on the material platform 52 based on the guard plate 51. A partition loading area is formed between the parts of the plurality of guard rods 53 that protrude from the material platform 52, the material platform 52 and the guard plate 51, and the partition loading area includes a stacking area located at the lower part and a layer separation area located at the upper part.

[0061] In some specific embodiments, the material platform 52 is provided with adjustment grooves 520 arranged along its own length and width directions, and each fence 53 passes through the adjustment groove 520. Based on the partitions of different sizes, the fence plate 51 is used as a reference, and the fence 51 is used to move the fence 53 to form a partition loading area that matches the partition shape.

[0062] In this example, each fence 53 comprises a rod body 530 and a layering module 531 located on top of the rod body 530. The rod body 530, the guard plate 51, and the material platform 52 form a stacking area, while the layering module 531 and the guard plate 51 form a layering area, with the cross-sectional area of the layering area being smaller than that of the stacking area. This arrangement facilitates aligned stacking in the large stacking area, followed by the arched, deformed layering formed by the smaller layering area, facilitating the piece-by-piece feeding of the separators. In some embodiments, two rod bodies 530 are arranged along the short sides of the separators (spaced arrangement) and three rod bodies 530 are arranged along the long sides (spaced arrangement). The side surfaces of each layering module 531 forming the layering area have toothed surfaces c extending horizontally and arranged side by side in the vertical direction. The horizontally aligned toothed surfaces of each layering module 531 and the guard plate 51 form a single layer, with each separator embedded in the layer from the side. This sequential arrangement of multiple layers further enhances the layering of the separators. In some specific embodiments, an air pipe 54 is provided on the back of each rod body 530, and at least one exhaust hole c1 connected to the air pipe 54 is formed on each tooth groove surface c, wherein the exhaust hole c1 ejects deionized gas from two or three sides simultaneously. Based on the ejection of deionized gas, not only the static electricity between the stacked partitions is eliminated, but also the gas flow is more conducive to the stratification between the upper and lower partitions. In some specific embodiments, in order to avoid two partitions entering the layer partition area at the same time when the stacking area is replenishing materials to the layer partition area, so as to keep one partition in each single compartment and reduce the probability of adsorption of two partitions, the brush 55 is used in this example to form a sweeping obstacle to rub away the partition that is replenished upward. Specifically, the brush 55 is located between the two rod bodies 530 on one side of the short side, and the brush 55 is correspondingly arranged in the transition area between the layer partition area and the stacking area (generally, it is arranged at the bottom tooth groove and extends into the layer partition area.)

[0063] In summary, the implementation process of this embodiment is as follows:

[0064] S1. Material frame alignment, transfer and replacement

[0065] After the material frame enters the feeding position of the material preparation station, it is first subjected to alignment correction, wherein the alignment correction is based on one end of the material frame, and the center line of the material frame in the length direction is aligned with the center line of the feeding position through the movement friction adjustment of the two sides. Then, based on the shifting of the carrier at the material preparation station, the corrected material frame is moved forward with the corrected posture to complete the automatic filling of the material frame in the material discharge position. At the same time, the material frame is taken out from the material discharge position and is horizontally loaded to the framing station with the corrected posture.

[0066] S2. Screen framing

[0067] The screen robot is used to transfer the screen to the framing station by suction, and then the screen is aligned and placed into the material frame;

[0068] S3, partition frame

[0069] First, the stacked partition rack is placed on the material table, and with one side of the material table as the reference plane, multiple fences moving along the length and width of the material table are fitted to the side edges of the stacked partitions to align the partitions, and the multiple fences and the material table constitute a stacking area at the bottom and a layer separation area at the top, wherein the side surfaces of the layer separation area are toothed surfaces extending horizontally from top to bottom; secondly, the material table is lifted to fill the spacers of the stacking area to the layer separation area, and the brushes between the layer separation area and the stacking area are used to relatively rub the two areas apart. The partitions are formed so that the middle of the single-layer partition is deformed and arched upward, and the side edges are wedged into the aligned tooth grooves. At the same time, the partitions are gradually moved upward to the upper tooth grooves. The airflow in the length and width directions of the partitions formed by the tooth groove surfaces eliminates static electricity and assists in delamination. The tooth groove surfaces of the layer partition areas are filled in sequence. Finally, the partition robot uses negative pressure to absorb the middle of the top layer of the partition in the layer partition area and shakes it up and down to flatten the partition. The partition is then transferred and laid on the surface of the screen to complete the framing, and the top tooth groove is filled at the same time.

[0070] S4, stacking frame and unloading

[0071] Repeat steps S2 and S3 in sequence to complete the intermittent stacking and framing of the screen and the partitions, and the material frame is unloaded and removed from the framing station by the feeding unit.

[0072] In summary, after adopting the framing process, first, the material frame is aligned, transferred and replenished, wherein the material frame is first aligned and corrected after entering the feeding position of the material preparation station, and then the corrected material frame is moved forward with the correction posture based on the shifting of the carrier at the material preparation station to complete the automatic replenishment of the material frame in the material discharge position of the material preparation station, and at the same time, the material frame is taken out from the material discharge position and is horizontally loaded to the framing station with the correction posture; secondly, the screen is adsorbed and transferred to the framing station based on the screen robot, and the screen is aligned and placed in the material frame; then the partitions are layered first, and then the partitions are framed, wherein the stacked partitions are placed on the material table when the partitions are layered, and the sides of the stacked partitions are fitted based on the movement of multiple surrounding rods to align the partitions, and multiple surrounding rods The material platform forms a stacking area at the bottom and a layer separation area at the top; then the material platform is lifted upwards to move the partitions in the stacking area to the layer separation area, and at the same time, the partitions in the layer separation area are first rubbed apart by the side brushes to make each partition wedged into the aligned tooth grooves from the side, and the middle of each partition is arched upwards to form partition layers. When the partitions are framed, when one partition is completed in the stacking area, the partitions in the layer separation area are gradually moved upwards, and the airflow blown out from the tooth grooves enters between each two adjacent partitions to eliminate static electricity and assist in stratification. At the same time, the partition robot is adsorbed from the middle of the top partition, and the side of the top partition is detached from the top tooth groove and reset to a horizontal state, and then the partition is transferred and laid on the screen The screen surface layer; finally, the partition framing and partition framing are repeated to complete the interleaved stacking framing of the screen and the partitions, and the material frame is unloaded and removed from the framing station by the feeding unit. Therefore, on the one hand, the present invention is based on the feeding correction of each material frame, and keeps the corrected posture to move forward and reprint, so that the material frame is accurately located at the framing station, reducing the probability of screen bumping or partition wrinkling due to material frame offset; on the other hand, based on the division of the stacking area and the layer separation area, without being restricted by the size of the partition, the stacking area is used to feed the partition to the layer separation area, and the two layers of partitions are rubbed apart by the obstruction formed by the brush, so that each partition is in an arched state and embedded in each tooth groove, and the partition is always kept in a layered state upward as the material platform is lifted. Filling, at the same time, multi-directional airflow blowing during the upward filling process not only eliminates static electricity, but also can further assist in stratification, so that each partition can be adsorbed and taken out with zero error, and avoids the phenomenon of multi-layer partitions being adsorbed and framed at one time; the third aspect is based on the position calibration formed by the feeding position, so that each material frame is transferred forward after correction, and the corrected material frame is transferred to the work station relatively stably through the carrier, reducing the deviation of the material frame caused by the material frame loading process, wherein each material frame is transferred from the feeding position to the discharging position, and the transfer path is an upward, forward, downward and backward circular transfer path, and the carrier transfers the material frames on each preparation station forward one by one along the circular transfer path to fill the position;The fourth aspect adopts two L-shaped relative movements to realize the correction of the length and width directions of the material frame, which not only optimizes the correction structure, but also makes the position on the carrier relatively consistent. Moreover, the roller that moves synchronously with the L-shaped correction arm can form a reference end face during the correction process, and it is easier to implement the material frame rotation correction under the resistance of the roller, thereby improving the correction efficiency and accuracy. The fifth aspect is based on the adjustability of the fence to meet the placement of partitions of different sizes. At the same time, the stacked partitions are further aligned in the adjustment of the fence to reduce the probability of misalignment and stacking of the partitions. At the same time, based on the grid reference, the partitions are aligned and stacked during the movement of the fence, which is more conducive to the gradual feeding of the partitions. The sixth aspect implements alignment and stacking through a large-area stacking area, and then forms an arched deformation layer by layer formed by a small-area layer partition, which is more conducive to the piece-by-piece feeding of the partitions. Moreover, based on the sequential layout of multiple monomer partitions, the partitions are better formed into piece-by-piece layers. The seventh aspect is based on the ejection of deionized gas, which not only eliminates the static electricity between the stacked partitions, Moreover, the gas flow is more conducive to the stratification between the upper and lower partitions; the eighth aspect is that the main function of the brush is to avoid two partitions entering the layer partition area at the same time when the stacking area is feeding the material to the layer partition area, so as to keep one partition in each single layer and reduce the probability of adsorbing two partitions; the ninth aspect is to avoid adsorbing two partitions by shaking when adsorbing a single partition, and at the same time, the shaking process is also conducive to restoring the natural state of the partition, avoiding the partition wrinkles during framing and affecting the stability of the stacked framing; the tenth aspect is to use multiple lines for framing and unloading to reduce the frequency of user collection, and when one of the lines fails, the other lines can still work normally for framing, which can increase the framing efficiency. At the same time, the partition loading unit is aligned side by side with the framing station, and the partition loading unit and the discharge position are located on opposite sides of the framing station, and the screen loading unit is located on the same side of the partition loading unit, the framing station and the discharge position. Based on the position layout, the structure is more compact and convenient for framing operation.
