Description

Technical Field

[0001] This utility model relates to the field of thick film production technology, and in particular to a drying storage rack. Background Technology

[0002] Thick-film printing technology has important applications in the field of light source manufacturing. The production process of thick-film printing involves multiple steps, including printing, conveying, transfer, drying, sintering, reflow, and unloading. However, existing production processes and equipment have significant shortcomings in terms of efficiency, precision, and automation. First, the lack of a dynamic adjustment mechanism for production quantity control leads to overproduction, resulting in material accumulation, wasted storage space, and a decrease in yield due to environmental factors. Furthermore, chaotic material management exacerbates the complexity of production traceability and retrieval. Second, manual operation accounts for too high a proportion of processes such as transfer, drying, and reflow. This not only requires a large amount of manpower for loading and unloading, carrier transfer, and cooling operations, but also increases the risk of product mixing and the defect rate due to reliance on hand tools (such as tweezers and gloves). Additionally, the material handling carts occupy a large amount of space.

[0003] Furthermore, existing production lines mostly employ a fragmented approach, combining decentralized equipment with manual workstations at connecting stations. This results in low equipment integration, redundant layouts, large floor space requirements, complex material handling, and poor system scalability. Adding workstations requires additional connecting stations and track modules, necessitating a complete overhaul of the operating system and significantly increasing both modification and time costs. More critically, the frequent loading / unloading and fixture changes between processes are cumbersome, limiting the automation level of the production line. Especially in the critical stages between drying and sintering, manual intervention is still necessary, leading to inefficiency and potential material buildup due to operational delays.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.

[0134] like Figure 1 and Figure 2 The diagram shows a structural schematic of a drying storage rack according to an embodiment of the present invention. This drying storage rack is used in a thick film automated production line and is characterized by comprising:

[0135] The storage rack body 100 includes a reflux layer, a drying layer, and several storage layers arranged sequentially from bottom to top; a reflux conveyor chain assembly 400 is installed on the reflux layer; a drying oven 300 is provided on the drying layer; a storage rack conveyor chain assembly 200 is installed on each of the storage layers; a storage rack elevator assembly 600 is provided on the output side of the storage rack body 100, and the storage rack elevator assembly 600 is connected to the output end of the drying oven 300.

[0136] It should be noted that the storage rack body 100 serves as the basic framework of the entire drying storage rack, supporting and integrating various functional layers and components. The return layer is used for the return conveying of trays, ensuring their recycling. The return conveyor chain assembly 400 returns the trays to the previous process, eliminating the need for manual collection and transfer of empty trays, saving time and improving production efficiency. The drying layer is equipped with a drying furnace 300 for drying materials. The storage layer stores materials awaiting processing, improving space utilization. The storage rack conveyor chain assembly 200 transports temporarily stored trays to the next process. The storage rack elevator assembly 600 transports trays output from the drying furnace to the sintering furnace in the next process, achieving automated production and improving efficiency.

[0137] In this embodiment, the raw material cart section of the thick film production line is designed as a drying storage rack structure, and the drying furnace is integrated inside the drying storage rack, making the drying furnace and the storage rack a single unit. This integrated design significantly saves floor space and optimizes the spatial layout of the production line. By arranging the various functional shelves upwards within the drying storage rack, continuous and uninterrupted production is achieved, improving production efficiency and the seamlessness of product production. Since restarting the sintering furnace for heating consumes more energy than continuous operation, the continuous and uninterrupted production mode of the drying storage rack ensures that the sintering furnace operates at full load, avoiding energy losses caused by frequent start-ups and shutdowns, thereby saving energy.

[0138] Furthermore, the material rack lifting assembly within the drying storage rack replaces the manual transfer process, and the conveying system of the drying storage rack enables automatic material distribution, reducing manual operation steps and the transfer between fixtures and turnover carts. This converts manual transfer time into production time, standardizes fixtures, and improves production efficiency.

[0139] By installing external sealing plates on the drying storage rack, products are directly transferred to the rack for storage, reducing manual contact and achieving a sealed protection effect. This effectively avoids adverse conditions caused by external influences on the production of products and improves product quality.

[0140] In one embodiment, such as Figure 1 and Figure 2 As shown, the storage rack body 100 is also equipped with an electrical control box 500 and a temperature control box 700; the electrical control box 500 is used to provide power; the temperature control box 700 is used to control the temperature of the drying oven 300.

[0141] The temperature control box 700 is the temperature regulation system of the drying oven 300. It detects the temperature inside the drying oven 300 through sensors and controls heating or cooling according to preset temperature parameters to ensure that the material inside the drying oven 300 is dried at a suitable temperature, guaranteeing drying effect and quality. The temperature control box 700 can also control the conveyor speed, temperature display, and operation and stop of the drying oven. Each temperature zone inside the drying oven can be equipped with its own temperature control box. Both the electrical control box 500 and the temperature control box 700 are mounted on the storage rack body 100. This layout facilitates centralized management and maintenance of the equipment, and also facilitates electrical connections and signal transmission between components.

[0142] In one embodiment, such as Figure 3 As shown, the storage rack lifting assembly 600 includes:

[0143] The hoist frame 610 includes a top sealing plate 611 and a bottom sealing plate 612, which are connected by a guide shaft 613. A first motor mounting base 620 and a first bearing mounting base 621 are mounted on the bottom sealing plate 612. A first motor 622 is fixed to the first motor mounting base 620. The shaft of the first motor 622 passes through the first bearing mounting base 621. A first synchronous pulley 623 is mounted on the shaft of the first motor 622. A hoist drag chain 614 is provided on one side of the hoist frame 610. A first sensor bracket 615 is provided on the hoist drag chain 614. A first sensor 616 is mounted on the first sensor bracket 615.

[0144] A hoist belt assembly 630 is mounted on the hoist frame 610; the hoist belt assembly 630 is connected to the first synchronous pulley 623 via a first belt 624.

[0145] A double-sided linear guide rail assembly 640 is fixedly installed on the hoist frame 610; the double-sided linear guide rail assembly 640 is fixedly connected to the hoist belt assembly 630;

[0146] The hoist conveyor chain assembly 650 is connected to the hoist drag chain 614 and is mounted on the double-sided linear guide rail assembly 640.

[0147] It should be noted that the top sealing plate 611 and the bottom sealing plate 612 of the elevator serve to seal and support. The guide shaft 613 connects the top sealing plate 611 and the bottom sealing plate 612 of the elevator, serving to guide and support, and ensuring the stable operation of the storage rack elevator assembly 600.

[0148] The hoist frame 610 is equipped with a hoist belt assembly 630, a double-sided linear guide rail assembly 640, and a hoist conveyor chain assembly 650. The hoist belt assembly 630 is fixedly connected to the double-sided linear guide rail assembly 640, and the hoist conveyor chain assembly 650 is mounted on the double-sided linear guide rail assembly 640. The hoist belt assembly 630 is used to pull the hoist conveyor chain assembly 650, and the double-sided linear guide rail assembly 640 is used to drive the hoist conveyor chain assembly 650 and control its left and right movement, guiding and limiting its movement.

[0149] Specifically, there are two guide shafts 613, which are arranged in parallel on both sides of the hoist frame 610. One end of each guide shaft 613 is connected to the top sealing plate 611 of the hoist, and the other end is connected to the bottom sealing plate 612 of the hoist. The guide shafts 613 are used to provide guidance for the hoist conveyor chain assembly 650.

[0150] When the first motor 622 starts, it drives the first synchronous pulley 623 to rotate. When the first synchronous pulley 623 rotates, it drives the first belt 624 sleeved on the first synchronous pulley 623 to rotate, thereby driving the hoist belt assembly 630 connected to the first belt 624 to move.

[0151] The elevator drag chain 614 is installed on one side of the elevator frame 610, connected to the elevator conveyor chain assembly 650, and moves in the same direction as the entire storage rack elevator assembly 600. The elevator drag chain 614 is used to prevent frictional damage to the wires and air pipes when the elevator conveyor chain assembly 650 conveys the material trays, making the wiring and air path layout of the elevator conveyor chain assembly 650 more reasonable and easier to maintain and inspect.

[0152] The first sensor 616 is used to detect whether the material tray inside the material rack of the storage rack body 100 is in place, and to detect whether there are obstacles at the upper and lower conveying positions of the material tray.

[0153] In one embodiment, such as Figure 4 As shown, the elevator belt assembly 630 includes: a drive shaft 631 and a rotating shaft 632; wherein,

[0154] The drive shaft 631 and the rotating shaft 632 are arranged in parallel. Two parallel synchronous belts 633 are connected between the drive shaft 631 and the rotating shaft 632. One end of each synchronous belt 633 is connected to both ends of the drive shaft 631 via two second synchronous pulleys 633a. The other end of each synchronous belt 633 is connected to both ends of the rotating shaft 632 via two second synchronous pulleys 633a. A second bearing mounting seat 631a is also provided at both ends of the drive shaft 631 and the rotating shaft 632. A belt tensioning mounting seat 631b is provided on the second bearing mounting seats 631a at both ends of the rotating shaft 632. A third synchronous pulley 635 is installed in the middle of the rotating shaft 632. A counterweight 634 is provided on each synchronous belt 633. A belt pressure plate 634a is provided at one end of the counterweight 634 that contacts the synchronous belt 633, and a bearing 634b is provided at the other end of the counterweight 634.

[0155] It should be noted that there are four second bearing mounting seats 631a, which are respectively installed at both ends of the transmission shaft 631 and the two ends of the rotating shaft 632, and are used to fix the transmission shaft 631 and the rotating shaft 632.

[0156] There are four second synchronous pulleys 633a, which are respectively installed at both ends of the drive shaft 631 and the two ends of the rotating shaft 632. A synchronous belt 633 is fitted between the second synchronous pulley 633a at one end of the drive shaft 631 and the second synchronous pulley 633a at the same end of the rotating shaft 632. Another synchronous belt 633 is fitted between the second synchronous pulley 633a at the other end of the drive shaft 631 and the second synchronous pulley 633a at the same end of the rotating shaft 632. The two synchronous belts 633 are arranged symmetrically and parallel to each other.

[0157] The second bearing mounting seats 631a at both ends of the rotating shaft 632 are also provided with belt shaft tensioning mounting seats 631b, which are used to control the tension of the two synchronous belts 633.

[0158] The guide shaft 613 passes through the mounting bearing 634b and is fixedly connected to the hoist belt assembly 630. The belt pressure plate 634a is used to fasten the timing belt 633.

[0159] When the first motor 622 rotates, it drives the rotating shaft 632 to rotate via the first belt 624, which in turn drives the synchronous belt 633. When the synchronous belt 633 moves up and down, it drives the counterweight 634 to move together.

[0160] In one embodiment, such as Figure 5 As shown, the double-sided linear guide assembly 640 includes:

[0161] Two parallel linear guide mounting plates 641 are arranged symmetrically from left to right. A first linear guide 641a is fixedly mounted on each of the linear guide mounting plates 641. Limit blocks 641b are respectively provided at both ends of each first linear guide 641a. A corresponding slider is installed on each first linear guide 641a. A second sensor 641c is installed on one of the linear guide mounting plates 641.

[0162] A double slider connecting plate 642 is provided, with its two ends fixedly connected to sliders on two first linear guide rails 641a respectively; a linear guide rail component 642a and a hoist transfer limiting component 642b are installed on the upper surface of the double slider connecting plate 642; and a rodless cylinder 642c is installed on the lower surface of the double slider connecting plate 642.

[0163] The sliders on the two first linear guide rails 641a are also fixedly connected to slider adapter fixing blocks 643 respectively; a synchronous belt clamping block 643a is installed on the slider adapter fixing block 643; a first drag chain bracket mounting plate 644 is provided on the linear guide rail mounting plate 641 on which the second sensor 641c is installed, and the first drag chain bracket mounting plate 644 is fixed on the slider adapter fixing block 643; a hoist sensing plate 643b is also provided on the slider adapter fixing block 643;

[0164] A second cable chain bracket mounting plate 645 is mounted on the double slider connecting plate 642; a first cable chain groove 646 connects the first cable chain bracket mounting plate 644 and the second cable chain bracket mounting plate 645; a solenoid valve 646a is provided on the first cable chain groove 646; a hoist cable chain connecting plate 647 is also mounted on the second cable chain bracket mounting plate 645; a second cable chain groove 647a is installed on the top of the hoist cable chain connecting plate 647.

[0165] Specifically, the linear guide mounting plate 641 is used to fix the first linear guide 641a, ensuring its installation stability and accuracy. The first linear guide 641a provides a precise linear motion path and also limits the movement range of the slider through the limiting blocks 641b installed at both ends, preventing the slider from exceeding the guide's stroke. The second sensor 641c is used to detect the slider's position and determine whether the slider exceeds its allowable movement range, i.e., to detect whether it exceeds the limit.

[0166] The two ends of the double-slider connecting plate 642 are respectively connected to the sliders on the two first linear guide rails 641a, thus maintaining synchronization with the movement of the sliders. The double-slider connecting plate 642 also supports the hoist conveyor chain assembly 650. The linear guide rail component 642a is used to control the left and right movement of the hoist conveyor chain assembly 650, and the hoist transfer limiting component 642b is used to limit the movement of the hoist conveyor chain assembly 650. The solenoid valve 646a is used to control the opening and closing of the rodless cylinder 642c, which provides power.

[0167] The timing belt clamping block 643a is fastened to the slider adapter fixing block 643, and the belt pressure plate 634a on the hoist belt assembly 630 presses the timing belt 633 onto the timing belt clamping block 643a. When the first motor 622 rotates, it drives the timing belt 633 to rotate. Since the timing belt 633 is connected to the first linear guide rail 641a through the slider adapter fixing block 643, the movement of the timing belt 633 drives the first linear guide rail 641a to move. The hoist sensor plate 643b is used to sense whether the hoist conveyor chain assembly 650, which is installed on the double slider connecting plate 642, exceeds the limit during operation.

[0168] In one embodiment, such as Figure 6 As shown, the elevator conveyor chain assembly 650 includes:

The return conveyor chain drive shaft 653e passes through the first sprocket 653c and the second sprocket 653d and is mounted on the return sprocket shaft fixing plate 653a via the first ball bearing 653b. The reducer 653f is drivenly connected to the return conveyor chain drive shaft 653e.

[0172] It should be noted that the pulley assembly 652 is connected to the return conveyor drive assembly 653. The movement of the pulley assembly 652 drives the material tray to move, thereby conveying the material tray to the subsequent process. The third sensor 659 is used to sense whether the material tray 652c is placed in the correct position before proceeding to the next conveying operation. All the material trays in the entire drying storage rack are reusable. The return conveyor drive assembly 653 can also recycle empty material trays to the previous process for material collection.

[0173] In one embodiment, such as Figure 6 As shown, the elevator conveyor chain assembly 650 further includes:

[0174] A conveying drive assembly 654 is installed at the lower end of the main body profile 651. The conveying drive assembly 654 includes two symmetrically arranged support plates 654a.

A second motor 654e is installed on the second motor mounting seat 654d.

[0175] Specifically, the conveyor drive assembly 654 provides power to the pulley assembly 652 and the return conveyor drive assembly 653, thereby realizing the conveying function of the material tray. The elevator conveyor chain assembly 650 is mounted on the double slider connecting plate 642 of the double-sided linear guide assembly 640, and the linear guide component 642a on the double slider connecting plate 642 is fastened to the mounting plate 654b of the elevator conveyor chain assembly 650. The two support plates 654a and the mounting plate 654b constitute a stable mounting platform. The two second linear guides 654c are used to support and guide the movement of the second motor mounting base 654d. The second motor 654e is the power source of the conveyor drive assembly 654.

[0176] In one embodiment, such as Figure 6 As shown, the elevator conveyor chain assembly 650 further includes:

[0177] A power transmission assembly 655 is mounted on the second motor mounting base 654d of the conveyor drive assembly 654. The power transmission assembly 655 includes a power transmission mounting base 655a, a power transmission mounting block 655b, a power component gear cover 655c, and a power component proximity mounting plate 655d. The power transmission mounting base 655a is mounted on the second motor mounting base 654d. The power transmission mounting block 655b is mounted on the power transmission mounting base 655a. The power component gear cover 655c is also mounted on the power transmission mounting block 655b. The power component proximity mounting plate 655d is mounted on the side of the power transmission mounting block 655b. A proximity switch 656 is mounted on the power component proximity mounting plate 655d. A gear 657 is provided inside the power transmission mounting block 655b. The power transmission assembly 655 also includes a guide pin 658.

[0178] It should be noted that the power transmission unit 655 is mounted on and connected to the conveyor drive unit 654, and is used to transmit power from the second motor 654 of the conveyor drive unit 654 to the pulley group 652 via the gear 657 to realize the conveying of the material tray. The power transmission mounting base 655a, the power transmission mounting block 655b, and the power component gear cover 655c constitute a fixed support platform for mounting and protecting the gear 657. The proximity switch 656 is mounted on the power component proximity mounting plate 655d and is used to detect the position or movement status of the entire power transmission unit 655 to achieve precise movement control.

[0179] In one embodiment, such as Figure 7 As shown, the return conveyor chain assembly 400 includes:

[0180] The support body 410 includes two symmetrically parallel aluminum profiles 411 and two conveyor chain spacing positioning plates 412. The two conveyor chain spacing positioning plates 412 are located at the front and rear ends of the aluminum profiles 411 respectively and connect the two aluminum profiles 411. Each aluminum profile 411 has a groove 413, and a second sensor bracket 414 is installed on one side of the aluminum profile 411. The bottom of the second sensor bracket 414 is fixed on the conveyor chain spacing positioning plate 412, and a fourth sensor 415 is installed on the second sensor bracket 414.

[0181] The main sprocket assembly 420 includes a first sprocket 421, a second sprocket 422, and a chain support bar 423. The sprocket 421 and the second sprocket 422 are respectively mounted on the groove bar 413, and a chain is sleeved on the sprocket 421 and the second sprocket 422. The chain support bar 423 is used to support the chain.

[0182] A secondary sprocket assembly 430 is connected to the main sprocket assembly 420 for transmission. The secondary sprocket assembly 430 includes a return sprocket shaft fixing plate 431, a second ball bearing 432, a third sprocket 433, a fourth sprocket 434, a third belt 435, and a third motor 436. The return sprocket shaft fixing plate 431 is mounted on the aluminum profile 411, and the second ball bearing 432 is mounted on the return sprocket shaft fixing plate 431, connecting and fixing the third sprocket 433 through the second ball bearing 432. The fourth sprocket 434 and the third sprocket 433 are fitted with the third belt 435. The fourth sprocket 434 is mounted on the third motor 436.

[0183] The return conveyor chain assembly 400 is used for conveying empty trays of the return layer on the drying storage rack. The aluminum profile 411 is lightweight, high-strength, and has good processing properties, making it suitable for mechanical structures. The spacing between sprocket groups can be precisely controlled by the conveyor chain spacing positioning plate 412, ensuring the normal operation of the chain.

[0184] The power provided by the third motor 436 drives the fourth sprocket 434 to rotate. The rotation of the fourth sprocket 434 drives the third belt 435 to move, which in turn drives the third sprocket 433 to rotate, further driving the main sprocket assembly 420. The third sprocket 433 drives the chain of the main sprocket assembly 420 to rotate, and the first sprocket 421 and the second sprocket 422 also rotate accordingly, thereby realizing the conveying of empty material trays. The fourth sensor 415 is used to sense whether there are empty material trays on the material rack of the return layer. If there are, they are sent back to the previous process.

[0185] In one embodiment, such as Figure 8 As shown, the drying oven 300 includes:

[0186] The drying furnace body includes a furnace shell 310, an inner furnace chamber 320, and a bottom sealing plate 330; the inner furnace chamber 320 is disposed inside the furnace shell 310; the bottom sealing plate 330 is located at the bottom of the furnace shell 310.

[0187] The furnace shell 310 is filled with insulation cotton 311; the furnace shell 310 is provided with an input furnace opening and an output furnace opening along the conveying direction of the drying furnace, and a chain track 312 connects the input furnace opening and the output furnace opening; the chain track 312 passes through the furnace shell 310 and is located inside the inner furnace chamber 320; a pad 313 is provided on the input furnace opening and the output furnace opening respectively, and the pad 313 is used to raise the chain track 312; a furnace opening lifting partition 314 is also provided on the input furnace opening and the output furnace opening respectively; a drying furnace motor 315 is installed on the furnace shell 310, and the drying furnace motor 315 is used to drive the chain track 312;

[0188] The inner furnace chamber 320 is evenly distributed with several heating components 321 and several aluminum profile supports 322; a drying furnace exhaust pipe 340 is provided on one side of the drying furnace body, and one end of the drying furnace exhaust pipe 340 is connected to the furnace shell 310.

[0189] It should be noted that the pad block 313 is used to elevate the chain track 312, and several heating elements 321, which are heating tubes, are arranged below the chain track 312. The furnace opening lifting baffle 314 is used to seal the input furnace opening and the output furnace opening to retain the heat of the inner furnace chamber 320.

[0190] For example, a drying oven 300 is installed inside a drying storage rack, and the heat of the drying oven 300 is provided by heating tubes. When the thick film automatic production line starts working, the drying oven 300 automatically matches preset data according to the product being produced and heats up to the initial temperature of that product. A sensor is installed at the input furnace inlet. When the sensor detects that the material tray is conveyed to the furnace inlet, the chain track 312 inside the drying oven 300 starts to operate. The drying oven 300 is preset with four temperature zones: a first temperature zone, a second temperature zone, a third temperature zone, and a fourth temperature zone. The first and fourth temperature zones are set to be lower than the second and third temperature zones, serving as cooling zones, while the second and third temperature zones serve as heating zones. When the workpiece to be produced enters the first, second, and third temperature zones sequentially, the workpiece is gradually heated up. Upon entering the fourth temperature zone, the workpiece is cooled down earlier.

[0191] In the drying oven 300, if the drying time of the workpiece to be produced does not need to be too long, the speed of the chain track 312 can be increased to shorten the drying time, that is, the drying time can be adjusted by adjusting the speed.

[0192] To facilitate the demonstration of the drying and storage rack provided by this utility model for use in an automated thick film production line, the following specific embodiments are provided for illustration.

[0193] Suppose that the thick-film automated production line is currently producing two types of products, product A and product B. The production line will produce multiple products A and multiple products B. Multiple products A of the same model number are assigned corresponding virtual serial number trays (e.g., A0, A1, ..., An) to their respective trays. Similarly, multiple products B of the same model number are assigned corresponding virtual serial number trays (e.g., B0, B1, ..., Bn) to their respective trays.

[0194] The thick-film automated production line first produces product A, then product B. Assuming that product A printed by automatic printing machine 1 completes its printing process, fully loaded trays, each carrying product A and assigned virtual serial numbers (e.g., A0, A1, ..., An), are sequentially fed into the drying oven via the drying storage rack. When the drying oven's inlet senses the full trays, the chain track begins to operate. At this point, the oven temperature has reached the set parameters, and drying begins according to the chain track's transport process. Gases generated during drying are discharged through the oven's exhaust pipe. After a period of time, product A reaches the drying oven's outlet. The elevator conveyor chain assembly receives product A, and the storage rack elevator assembly transports product A out of the drying storage rack and into the next process, the sintering furnace.

[0195] Subsequently, when product B printed by automatic printing machine No. 2 completes the printing process, the fully loaded trays carrying product B and each assigned a virtual serial number (such as B0, B1, ..., Bn) are sequentially fed into the drying oven of the drying storage rack. After a period of time, the drying process is completed and the product is sent out of the drying oven and into the elevator conveyor chain assembly. However, at this time, the sintering furnace is sintering product A. Therefore, the elevator conveyor chain assembly sends product B to the storage layer of the drying storage rack for temporary storage. After product A is sintered, the temporarily stored product B will be sent to the sintering furnace for sintering through the storage rack conveyor chain assembly on the storage layer.

[0196] A return conveyor chain assembly is installed in the return layer of the drying storage rack. After product A is sintered, the storage rack elevator assembly sends the empty tray to the inlet of the return conveyor chain assembly. After sensing the empty tray, the return conveyor chain assembly rotates and transports the empty tray to the next printing process. This eliminates the need for manual collection of empty trays and transportation to the printing rack, saving time and improving work efficiency.

[0197] It is important to emphasize that this invention introduces a drying storage rack into the thick-film automated production line, enabling continuous and uninterrupted production of different products. This production mode ensures that the sintering furnace in subsequent processes can operate at full capacity, thereby significantly saving energy and reducing energy costs. Simultaneously, the drying storage rack adopts a multi-layer structure design, effectively improving space utilization and reducing the material turnover process within the production workshop. This improvement not only optimizes the production layout but also reduces product defect rates caused by environmental factors during material turnover, significantly improving product quality. Furthermore, through the storage rack lifting assembly, products can be directly conveyed to the sintering furnace or storage layer, achieving automated production. This automated process reduces frequent transfers between fixtures and transfer carts, unifies fixture management, reduces manual operation steps, and converts manual operation time into production time, further improving production efficiency and optimizing the overall production process.

[0198] In summary, this utility model provides a drying storage rack for a thick film automated production line, comprising: a storage rack body, which includes a reflux layer, a drying layer, and several storage layers arranged sequentially from bottom to top; a reflux conveyor chain assembly installed on the reflux layer; a drying furnace installed on the drying layer; and storage rack conveyor chain assemblies installed on each of the storage layers; a storage rack lifting assembly is provided on the output side of the storage rack body, and the storage rack lifting assembly is connected to the output end of the drying furnace.
