Description

Technical Field

[0001] This invention relates to the field of hot pressing equipment technology, and more specifically, to a hot pressing equipment for graphene products with automatic loading and unloading capabilities. Background Technology

[0002] A hot press is a device that heats two pre-fluxed and tinned parts to a temperature sufficient to melt and flow the solder. After solidification, a permanent electromechanical connection is formed between the parts and the solder. Graphene thermal comfort products and graphene thermal functional products both require processing using a hot press.

[0003] Currently, hot pressing equipment requires manual placement and removal of products by operators, which is not only dangerous but also has a low degree of automation. To improve these issues, operators have modified the equipment by adding conveyor belts, cylinders, slides, and suction cups to transform manual product placement into automatic feeding and discharging. However, while the existing equipment has solved the automation problem, other drawbacks remain. The mechanism for placing and removing products needs to reciprocate to complete the feeding and removal of a single product, and it must wait for the product to be hot-pressed before it can be removed, resulting in a low degree of feeding.

[0004] When the existing equipment is feeding flexible products, the suction cup lifts the product. At this time, the product will bend due to gravity and eventually bend into a downward arc shape. If it is kept in this state on the worktable, the bent part of the product is prone to folding. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a hot pressing equipment for graphene products with automatic loading and unloading.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a graphene product hot pressing equipment with automatic loading and unloading, comprising a main component, a plate changing module, a transfer module, a hot pressing mechanism, and a material handling mechanism installed inside the main component.

[0007] The main components include a chassis and a workbench horizontally installed inside the chassis. The tray changing module, hot pressing mechanism, and material handling mechanism are all installed on the top of the workbench. The hot pressing mechanism and material handling mechanism are located on one side of the tray changing module and are arranged in parallel. The transfer module is installed on the inner wall of the chassis and extends above the tray changing module and the hot pressing mechanism.

[0008] The tray changing module includes a conveyor belt installed on the top of the workbench, two guide plates installed on the top of the conveyor belt, a first feeding plate connected to the bottom of the conveyor belt, and a second feeding plate connected to the top surface of the conveyor belt. The second feeding plate is slidably connected between the two guide plates, and the first feeding plate and the second feeding plate are staggered.

[0009] The present invention is further configured such that: the main component also includes a cover installed on the top of the chassis and a first material port and a second material port opened on the front surface of the cover, the first material port corresponding to the plate changing module and the second material port corresponding to the material picking mechanism.

[0010] By adopting the above technical solution, the staff can feed materials by coordinating the tray changing module and the first feeding port. That is, the product is placed on top of the first feeding plate or the second feeding plate, and is conveyed by the conveyor belt clockwise or counterclockwise, so that the first feeding plate or the second feeding plate is alternately fed to the bottom of the transfer module. When the first feeding plate feeds, the second feeding plate moves out in the opposite direction, which makes it convenient for the staff to pick up and put down the material. When the second feeding plate feeds, the first feeding plate moves out, thus achieving the purpose of alternating feeding.

[0011] The present invention is further configured such that: the transfer module includes a fixed plate installed on the inner wall of the chassis and a first guide rail installed on the fixed plate, a gripping mechanism is slidably connected on the first guide rail, a positioning mechanism is installed at the bottom of the gripping mechanism, and a heavy-duty chain is connected between the top of the gripping mechanism and the front surface of the fixed plate.

[0012] The present invention is further configured such that: the gripping mechanism includes a cylinder slidably connected to a first guide rail, two slide rails connected to the piston rod of the cylinder, two connecting rods hinged to the two ends of opposite sides of the two slide rails, and a cylinder connected to the bottom of the connecting rods, wherein both slide rails are horizontally arranged.

[0013] Both of the cylinders have through grooves on their outer side walls, and scrapers are installed in the through grooves. A spring is connected between the outer wall of the scraper and the outer wall of the cylinder. A second micro push rod is installed inside each cylinder. The piston rod of the second micro push rod is connected to a push block. The bottom of the push block is in contact with the inner wall of the scraper.

[0014] The present invention is further configured such that: two first micro push rods are installed on one side of one of the slide rails, the piston rod of the first micro push rod passes through the two slide rails, and the piston rod of the slide rail is composed of two parts with different diameters. The connecting rod is sleeved on the part with the smaller diameter, and a tension spring is connected between the opposite sides of the two connecting rods.

[0015] The present invention is further configured such that: the positioning mechanism includes two support plates, both of which are slidably connected to the bottom of two slide rails, and two electric push rods are symmetrically installed on the top of each of the two support plates. The piston rods of the two electric push rods pass through the top of the corresponding support plates and are connected to suction cups, which are square in shape.

[0016] The present invention is further configured such that two bearing plates and two connecting rods are correspondingly arranged, and a tie rod is provided between the bearing plates and the corresponding connecting rods.

[0017] By adopting the above technical solution, when the first or second feeding plate moves the product to the bottom of the transfer module, the gripping mechanism slides on the first guide rail, causing both the gripping mechanism and the positioning mechanism to move above the product. Then, the cylinder pushes the slide rail, connecting rod, and cylinder downward according to the height of the product, causing the cylinder to contact the product surface. The cylinder then continues to apply thrust, and the two cylinders slide on the product surface and move away from each other until they slide off the product surface, thus flattening the product. During this process, the tension spring is gradually stretched, and the connecting rod drives the pull rod to move, causing the two bearing plates to slide at the bottom of the slide rail, thereby adjusting the distance between the two bearing plates. The spacing between the suction cups installed on the two bearing plates can be adjusted according to the product size, thereby improving the functionality of the transfer module.

[0018] When the cylinder retracts, the tension spring pulls the two connecting rods and the corresponding cylinder closer together, and the scraper moves to the bottom of the product. The second micro push rod retracts, and the spring causes the scraper to swing up to clamp the product. Finally, the electric push rod drives the square suction cup to adhere to the product surface, thereby achieving the purpose of adsorbing and gripping the product. The piston rod of the first micro push rod retracts, and the thicker part of the rod squeezes the connecting rod, thereby positioning the angle of the connecting rod. The transfer module can move the product from the changing plate module to the hot pressing mechanism for hot pressing. Afterward, the suction cup releases its grip on the product, the scraper swings downward away from the product, and then the cylinder drives the connected components and positioning mechanism to lift. Alternatively, the product can be moved from the hot pressing mechanism to the changing plate module, thereby achieving the purpose of automatic loading and unloading.

[0019] The present invention is further configured such that: the hot pressing mechanism includes a hot press and a cover, the hot press is mounted on the top of the workbench, and the cover is hinged to one side of the top of the hot press.

[0020] The present invention is further configured such that: the material handling mechanism includes a support, the support is mounted on the top of the workbench and located in front of the hot press, a second guide rail is mounted on the top of the support, one end of the second guide rail extends above the hot press, and an adsorption component is slidably connected to the bottom of the second guide rail.

[0021] By adopting the above technical solution, when the transfer module moves the product onto the hot press mechanism, the cover covers the hot press. The hot press uses pulse heating technology to heat and hot press the product on both sides, increasing production capacity. After the product is hot-pressed, it can be removed by the transfer module or discharged by the adsorption component. The adsorption component has a similar structure to the positioning mechanism, that is, it uses a combination of a telescopic rod and a suction head. When the adsorption component moves above the hot press via the second guide rail, the telescopic rod of the adsorption component pushes the suction head to move above the hot press to pick up and lift the product. Then, the second guide rail and the adsorption component work together to discharge the product through the second discharge port. This setting saves the discharge time of the transfer module, that is, while the hot press is hot-pressing a product, the transfer module is transferring the next product, which greatly improves the operating efficiency of the equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] (1) By setting up a plate changing module, the plate changing module performs feeding and discharging operations according to the equipment operation status, which is divided into feeding state and feeding and discharging combined state. When the plate changing module is in the feeding and discharging state, the first and second discharging plates are both used as feeding carriers. When the plate changing module is in the feeding state, the first feeding plate is the feeding carrier and the second feeding plate is the discharging carrier. The conveyor belt is used to transport the material clockwise or counterclockwise, thereby achieving the purpose of alternating feeding and discharging.

[0024] (2) By setting up a gripping mechanism, when the cylinder controls the cylinder to fall to the product surface and slide away from each other, it can flatten the product. When the two cylinders approach each other, the scraper moves to the bottom position of the product. The second micro push rod retracts, and the spring drives the scraper to swing up to clamp the product. The piston rod of the first micro push rod retracts to squeeze the connecting rod, thereby positioning the angle of the connecting rod. This setting allows the gripping mechanism to be compatible with products of different sizes and materials, and keeps the product in a horizontal state, avoiding bending and folding when the product is placed, and ensuring the integrity of the product during hot pressing.

[0025] (3) During the swinging process of the two connecting rods, the tension spring is gradually stretched, and the connecting rod drives the pull rod to move, causing the two bearing plates to slide at the bottom of the slide rail, thereby adjusting the distance between the two bearing plates. The distance between the suction cups installed on the two bearing plates can be adjusted according to the product size to improve the functionality of the transfer module.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0040] Please see Figure 1-11 The present invention provides the following technical solutions:

[0041] Example 1

[0042] See Figures 1-3 An automatic graphene product hot pressing device includes a main component 1, a plate changing module 2, a transfer module 3, a hot pressing mechanism 4, and a material handling mechanism 5 installed inside the main component 1. The main component 1 is used to support each module and mechanism. The plate changing module 2 is used to support the product and performs feeding and discharging operations according to the equipment operation, that is, it is divided into feeding state and feeding and discharging combined state. The transfer module 3 is used to transfer the product from the plate changing module 2 to the hot pressing mechanism 4 or from the hot pressing mechanism 4 to the plate changing module 2. The hot pressing mechanism 4 is used to perform hot pressing operations on the transferred product. When the plate changing module 2 is in the feeding state, the material handling mechanism 5 is used to discharge the product on the hot pressing mechanism 4.

[0043] See Figures 1-2 The main component 1 includes a chassis 11 and a workbench 14 horizontally installed inside the chassis 11. A cover 12 is installed on the top of the chassis 11. The cover 12 and the chassis 11 work together to protect the workbench 14. The front surface of the cover 12 has a first material port 13 and a second material port 15. The first material port 13 corresponds to the tray changing module 2, and the second material port 15 corresponds to the material picking mechanism 5. The tray changing module 2, the hot pressing mechanism 4, and the material picking mechanism 5 are all installed on the top of the workbench 14. When the tray changing module 2 is in the feeding and discharging state, the first material port 13 serves as a feeding and discharging window to facilitate the workers to pick up and put down products. When the tray changing module 2 is in the feeding state, the second material port 15 serves as a discharging window to facilitate the workers to pick up products.

[0044] See Figure 3 The hot pressing mechanism 4 and the material handling mechanism 5 are both located on one side of the changing plate module 2 and are arranged in parallel. The transfer module 3 is installed on the inner wall of the chassis 11 and extends above the changing plate module 2 and the hot pressing mechanism 4. The position of the transfer module 3 switches between the changing plate module 2 and the hot pressing mechanism 4, so that the transfer module 3 can transfer products between the two. The operation of the material handling mechanism 5 and the transfer module 3 does not interfere with each other, so the material handling mechanism 5 can also perform material discharge operation.

[0045] See Figures 3-4The tray changing module 2 includes a conveyor belt 21 mounted on top of the workbench 14, two guide plates 22 mounted on top of the conveyor belt 21, a first feeding plate 23 connected to the bottom of the conveyor belt 21, and a second feeding plate 24 connected to the top surface of the conveyor belt 21. The second feeding plate 24 is slidably connected between the two guide plates 22. The first feeding plate 23 and the second feeding plate 24 are staggered. When the tray changing module 2 is in the feeding state, both the first feeding plate 23 and the second feeding plate 24 are feeding carriers. The operator uses the changing plate module 2 and the first feeding port 13 to feed the product. The product is placed on top of the first feeding plate 23 or the second feeding plate 24 and conveyed clockwise or counterclockwise by the conveyor belt 21. This alternately feeds the first feeding plate 23 or the second feeding plate 24 to the bottom of the transfer module 3. When the first feeding plate 23 feeds, the second feeding plate 24 moves out in the opposite direction, which makes it convenient for the operator to pick up and put down the product. When the second feeding plate 24 feeds, the first feeding plate 23 moves out, thus achieving the purpose of alternating feeding.

[0046] Specifically, under normal equipment conditions, the plate changing module 2 switches to the feeding and discharging state. The operator places the product to be hot-pressed on the first feeding plate 23. The transfer module 3 moves the product on the first feeding plate 23 to the hot pressing mechanism 4 for hot pressing. The hot-pressed product is then moved again to the second feeding plate 24 by the transfer module 3, and the second feeding plate 24 sends the product out.

[0047] To improve equipment efficiency, the tray changing module 2 is switched to feeding mode. Workers use the tray changing module 2 and the first feeding port 13 to alternately feed materials onto the first feeding plate 23 and the second feeding plate 24. Specifically, when the product is placed on top of either the first or second feeding plate 24, the second feeding plate 24 moves out in the opposite direction while the first feeding plate 23 is feeding, facilitating material handling. Conversely, when the second feeding plate 24 is feeding, the first feeding plate 23 moves out. Once a product is placed on one of the feeding plates, it is conveyed clockwise or counterclockwise by the conveyor belt 21, alternately feeding either the first or second feeding plate 24 to the underside of the transfer module 3. The transfer module 3 then switches positions between the tray changing module 2 and the hot pressing mechanism 4, moving the product from the tray changing module 2 to the hot pressing mechanism 4 for hot pressing. Finally, the product is discharged by the material handling mechanism 5. This process is repeated to achieve alternating feeding and improve equipment operating efficiency.

[0048] Example 2

[0049] See Figure 5 and Figure 6The transfer module 3 includes a fixing plate 31 installed on the inner wall of the chassis 11 and a first guide rail 32 installed on the fixing plate 31. A gripping mechanism 34 is slidably connected on the first guide rail 32. A positioning mechanism 35 is installed at the bottom of the gripping mechanism 34. The fixing plate 31 is used to position the transfer module 3 as a whole. The first guide rail 32 is used to drive the gripping mechanism 34 and the positioning mechanism 35 to switch positions between the plate changing module 2 and the hot pressing mechanism 4.

[0050] See Figure 6 A heavy-duty chain 33 is connected between the top of the gripping mechanism 34 and the front surface of the fixed plate 31. When the gripping mechanism 34 is displaced, the end of the heavy-duty chain 33 connected to the gripping mechanism 34 moves synchronously with the gripping mechanism 34. This not only serves as a guide but also increases the load-bearing capacity of the gripping mechanism 34, preventing the gripping mechanism 34 and the positioning mechanism 35 from tilting.

[0051] See Figures 6-8 The gripping mechanism 34 includes a cylinder 341 slidably connected to the first guide rail 32, two slide rails 342 connected to the piston rod of the cylinder 341, two connecting rods 344 hinged to opposite ends of the two slide rails 342, and a cylinder 345 connected to the bottom of the connecting rods 344. Both slide rails 342 are horizontally arranged. The cylinder 341 is used to adjust the height of the slide rails 342, connecting rods 344, and cylinder 345. The slide rails 342 support the connecting rods 344 and cylinder 345. When the cylinder 345 moves down to the product position, as the cylinder 341 continues to extend, the cylinder 345 slides on the product surface and the two cylinders 345 separate from each other. The two connecting rods 344 swing from a vertical state to an inclined state. A tension spring 340 is connected between the opposite sides of the two connecting rods 344. During the swinging process, the tension spring 340 is gradually stretched. Conversely, when the cylinder 341 retracts, the tension spring 340 pulls the two connecting rods 344 and the corresponding cylinders 345 closer to each other.

[0052] See Figure 8 Both cylinders 345 have through grooves on their outer side walls, and scrapers 349 are installed in the through grooves. A spring 348 connects the outer wall of the scraper 349 and the outer wall of the cylinder 345. A second micro push rod 346 is installed inside each cylinder 345. The piston rod of the second micro push rod 346 is connected to a push block 347. The bottom of the push block 347 is in contact with the inner wall of the scraper 349. When the cylinder 345 moves downward, the piston rod of the second micro push rod 346 extends, causing the push block 347 to push the scraper 349 downward to swing out of the through groove. When the two cylinders 345 approach each other, the piston rod of the second micro push rod 346 retracts, and the spring 348 drives the scraper 349 to swing upward to clamp the product, keeping the product in a horizontal state and preventing bending and folding when the product is placed, thus ensuring the integrity of the product during hot pressing.

[0053] See Figures 6-8 Two first micro push rods 343 are installed on one side of a slide rail 342. The piston rod of the first micro push rod 343 passes through the two slide rails 342, and the piston rod of the slide rail 342 is composed of two parts with different diameters. The connecting rod 344 is fitted onto the part with a smaller diameter. The piston rod of the first micro push rod 343 retracts, while the part with a larger diameter squeezes the connecting rod 344, thereby positioning the angle of the connecting rod 344.

[0054] See Figure 7 , Figure 9 and Figure 10 The positioning mechanism 35 includes two support plates 352, both of which are slidably connected to the bottom of two slide rails 342. Two electric push rods 351 are symmetrically mounted on the top of each support plate 352. The piston rods of the two electric push rods 351 pass through the top of the corresponding support plate 352 and are connected to suction cups 354, which are square in shape. The two support plates 352 and two connecting rods 344 are correspondingly arranged, and a pull rod 353 connects the support plate 352 and the corresponding connecting rod 344. The connecting rod 344 is in a vertical position. During the tilting swing, the pull rod 353 is displaced, causing the two support plates 352 to slide at the bottom of the slide rail 342, thereby adjusting the distance between the two support plates 352. The spacing between the suction cups 354 installed on the two support plates 352 can be adjusted according to the product size, thereby improving the functionality of the transfer module 3. The electric push rod 351 is used to drive the square suction cup 354 to move down, thereby adhering the square suction cup 354 to the product surface. Compared with the round suction head, the square suction cup 354 increases the contact surface with the product, thus better adsorbing the product.

[0055] Specifically, when the transfer module 3 grips the product, the gripping mechanism 34 slides on the first guide rail 32, causing both the gripping mechanism 34 and the positioning mechanism 35 to move above the product. Then, the cylinder 341 pushes the slide rail 342, connecting rod 344, and cylinder 345 downwards according to the product's height, causing the cylinder 345 to contact the product surface. During the downward movement of the cylinder 345, the piston rod of the second micro push rod 346 extends, causing the push block 347 to push the scraper 349 downwards and out of the through slot. Afterwards, the cylinder... 341 continues to apply thrust, and the two cylinders 345 slide on the product surface and move away from each other until they slide off the product surface, thereby flattening the product. During this process, the tension spring 340 is gradually stretched, and the connecting rod 344 drives the pull rod 353 to move, causing the two support plates 352 to slide at the bottom of the slide rail 342, thereby adjusting the distance between the two support plates 352. The spacing between the suction cups 354 installed on the two support plates 352 can be adjusted according to the product size to improve the functionality of the transfer module 3.

[0056] The cylinder 341 then retracts, and the tension spring 340 pulls the two connecting rods 344 and the corresponding cylinder 345 closer together. The scraper 349 moves to the bottom of the product and retracts through the second micro push rod 346. The spring 348 drives the scraper 349 to swing upward to clamp the product. Finally, the electric push rod 351 drives the square suction cup 354 to adhere to the product surface, thereby achieving the purpose of adsorbing and grasping the product. After the product adsorption is completed, the piston rod of the first micro push rod 343 retracts, and the thicker part squeezes the connecting rod 344, thereby positioning the angle of the connecting rod 344. The transfer module 3 can transfer the product from the changing plate module 2 to the hot pressing mechanism 4 for hot pressing. After that, the suction cup 354 releases the adsorption of the product, and the scraper 349 swings downward away from the product. Then the cylinder 341 drives the connected components and positioning mechanism 35 to lift up. Alternatively, the product can be transferred from the hot pressing mechanism 4 to the changing plate module 2, thereby achieving the purpose of automatic loading and unloading.

[0057] Example 3

[0058] See Figure 3 and Figure 5 The hot pressing mechanism 4 includes a hot press 41 and a cover 42. The hot press 41 is mounted on the top of the workbench 14. The cover 42 is hinged to one side of the top of the hot press 41. The hot press 41 is used to perform hot pressing operations on the product. When the hot press 41 performs hot pressing on both sides of the product, the cover 42 covers the hot press 41 and the product. The hot press 41 is existing technology and will not be described in detail here.

[0059] See Figure 5 and Figure 11 The material handling mechanism 5 includes a support 51, which is installed on the top of the workbench 14 and in front of the hot press 41. A second guide rail 52 is installed on the top of the support 51. One end of the second guide rail 52 extends above the hot press 41. An adsorption component 53 is slidably connected to the bottom of the second guide rail 52. The adsorption component 53 has a similar structure to the positioning mechanism 35. Using a combination of a telescopic rod and a suction head, the material handling mechanism 5 can operate when the tray changing module 2 is in the feeding state. The adsorption component 53 moves to the top of the hot press 41 via the second guide rail 52. The telescopic rod of the adsorption component 53 pushes the suction head to the top of the hot press 41 to pick up and lift the product. Then, the second guide rail 52 and the adsorption component 53 cooperate to discharge the product through the second feed port 15.

[0060] Specifically, when the changing plate module 2 is in the feeding state, the transfer module 3 moves the product to the hot pressing mechanism 4. The transfer module 3 then cancels the gripping of the product and moves back to the position of the changing plate module 2 to continue the gripping operation. During this process, the cover covers the hot press 41. The hot press 41 uses pulse heating technology to heat the product and perform double-sided hot pressing. After the product is hot pressed, it can be removed by the transfer module 3 or discharged by the adsorption component 53. The adsorption component 53 has a similar structure to the positioning mechanism 35, that is, it uses a combination of telescopic rod and suction head. When the adsorption component 53 moves above the hot press 41 via the second guide rail 52, the telescopic rod of the adsorption component 53 pushes the suction head to move above the hot press 41 to pick up and lift the product. Then, the second guide rail 52 and the adsorption component 53 work together to discharge the product through the second feed port 15. This setting saves the discharge time of the transfer module 3. That is, while the hot press 41 is hot pressing the product, the transfer module 3 is transferring the next product, which greatly improves the operating efficiency of the equipment.

[0061] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

A gripping mechanism (34) is slidably connected on the first guide rail (32). A positioning mechanism (35) is installed at the bottom of the gripping mechanism (34). A heavy-duty chain (33) is connected between the top of the gripping mechanism (34) and the front surface of the fixed plate (31). The gripping mechanism (34) includes a cylinder (341) slidably connected to the first guide rail (32), two slide rails (342) connected to the piston rod of the cylinder (341), two connecting rods (344) hinged to the two ends of opposite sides of the two slide rails (342), and a cylinder (345) connected to the bottom of the connecting rods (344). Both slide rails (342) are horizontally arranged. The outer walls of both cylinders (345) are provided with through grooves, and scrapers (349) are provided in the through grooves. A spring (348) is connected between the outer wall of the scraper (349) and the outer wall of the cylinder (345). A second micro push rod (346) is installed inside the cylinder (345). The piston rod of the second micro push rod (346) is connected to a push block (347). The bottom of the push block (347) is in contact with the inner wall of the scraper (349). Two first micro push rods (343) are installed on one side of one of the slide rails (342). The piston rod of the first micro push rod (343) passes through the two slide rails (342), and the piston rod of the first micro push rod (343) is composed of two parts with different diameters. The connecting rod (344) is sleeved on the part of the piston rod of the first micro push rod (343) with a smaller diameter. A tension spring (340) is connected between the opposite sides of the two connecting rods (344). When the cylinder (345) moves down to the product position, as the cylinder (341) continues to extend, the cylinder (345) slides on the product surface and the two cylinders (345) separate from each other. The two connecting rods (344) swing from a vertical state to an inclined state. A tension spring (340) is connected between the opposite sides of the two connecting rods (344). During the swinging process of the two connecting rods (344), the tension spring (340) is gradually stretched. Conversely, when the cylinder (341) retracts, the tension spring (340) pulls the two connecting rods (344) and the corresponding cylinders (345) closer to each other. As the cylinder (345) moves downward, the piston rod of the second micro push rod (346) extends, causing the push block (347) to push the scraper (349) to swing downward and move out of the through groove. When the two cylinders (345) approach each other, the piston rod of the second micro push rod (346) retracts, and the spring (348) drives the scraper (349) to swing upward to clamp the product, keeping the product in a horizontal state, avoiding bending and folding when the product is placed, and ensuring the integrity of the product during hot pressing.
