Description

Technical Field

[0001] This utility model mainly relates to the field of coating machine die assembly and disassembly technology, specifically to a safe assembly and disassembly structure for a precision die. Background Technology

[0002] With the rapid development of high-end materials such as lithium batteries, optics, photovoltaics, shielding, and flexible circuit board substrates, continuous and efficient production, and improving batch-to-batch stability have become key concerns in the thin film materials industry. Extrusion coating has attracted much attention and is the preferred choice in the industry because it allows for the closed-loop transport of the coating slurry, maximizing the stability of the adhesive.

[0003] Meanwhile, stabilizing coating thickness and ensuring consistent reproducibility between product batches has been a persistent challenge for the film industry. Therefore, the machining accuracy, installation accuracy, and repeatability during the installation process of the extrusion die are particularly crucial. While ensuring the design and machining accuracy of the die, the installation accuracy during use and the repeatability during production become paramount in affecting thickness consistency and uniformity.

[0004] In the current coating production process, the assembly and installation of extrusion dies are generally divided into two methods: assembly after hoisting and online disassembly / assembly. 1. Lifting and Assembly: This method involves using slings to pass the upper template through the lifting rings, then hoisting the die head to the disassembly and cleaning platform using a forklift for disassembly, cleaning, and reassembly, followed by further lifting and assembly. The advantage of this method is its relative simplicity; it does not require specific tooling fixtures, and the coating head is assembled on the disassembly and assembly platform, which helps ensure the assembly accuracy of the die head, making it the current assembly method for extrusion dies. However, the die head is suspended during lifting, making it prone to swaying and posing significant safety hazards, with accidents such as die head falls occurring frequently. Furthermore, the die head still needs to be lifted and reset after cleaning and assembly. During the lifting process, it is difficult to maintain the flatness and straightness of the upper and lower templates relative to the micron-level requirements of high-precision coating, often resulting in situations where disassembly and cleaning are fine, but abnormalities occur during reinstallation, ultimately leading to batch instability in the product.

[0005] 2. Online Disassembly and Assembly: This method involves cleaning and assembling the die head after use without moving it to a flat surface. The upper template is opened directly at the installation position for cleaning, followed by mold assembly for use. This method eliminates the risks associated with hoisting and is relatively simple to clean and assemble. However, the die head and mounting plate are not thoroughly cleaned, making it difficult to maintain hygiene over time, and accuracy gradually decreases. Furthermore, because the mold assembly is done at the installation position with limited operating space, it's difficult to ensure the upper and lower die lips are on the same vertical plane. In daily use, this often results in similar gaps on both sides of the die head, but significant differences in coating thickness. The root cause is the presence of non-linear lines on the upper and lower die lips. Although the distance on both sides is measured to be similar using a plug gauge, the actual die lip gaps controlling thickness uniformity are not the same, ultimately leading to abnormal thickness and compromising product repeatability.

[0006] Therefore, how to avoid the defects of the above two installation methods and improve operational safety and product consistency has become an urgent problem to be solved in the thin film industry. Utility Model Content

[0007] 1. The technical problem to be solved by the utility model: This utility model provides a safe disassembly and assembly structure for precision mold heads, in order to solve the technical problems existing in the background art.

[0008] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is: a safe assembly and disassembly structure for a precision mold head, including a mobile trolley with a placement plate on its top for supporting the mold head assembly; The disassembly track is detachably mounted on one side of the mobile trolley; The lifting and moving part is detachably connected to the other end of the disassembly and assembly track. The lifting and moving part is configured to be inserted into a preset mounting slot on the mold head mounting plate to achieve precise docking with the mold head mounting plate. The bearing assembly is slidably disposed on the top of the lifting and moving part and detachably mounted on both sides of the mold head assembly to be moved; The bottom of the mold head assembly is symmetrically provided with positioning grooves that cooperate with the positioning bosses in the mold head mounting plate to achieve automatic centering and positioning of the mold head assembly.

[0009] When cleaning or maintenance of the die head assembly is required, first connect one end of the disassembly / assembly track to the moving trolley and the other end to the lifting and moving part. Push the moving trolley to accurately insert the lifting and moving part into the mounting slot, ensuring the initial alignment accuracy of the entire disassembly / assembly system with the coating machine body. The coating machine is existing technology and will not be discussed further here.

[0010] Next, install the bearing assemblies on both sides of the mold head assembly to be disassembled. Loosen the connecting bolts between the mold head assembly and the mold head mounting plate, and operate the lifting and moving part to lift it upwards, so that the positioning groove at the bottom of the mold head assembly separates from the positioning boss on the mold head mounting plate. At this time, the rollers of the bearing assembly are flush with the upper surface of the disassembly and assembly track, and the operator can smoothly push the mold head assembly along the track onto the placement plate of the moving trolley.

[0011] After the mold head assembly is removed, the disassembly and assembly rails and lifting and moving parts are disassembled, and the mold head assembly is transferred to the cleaning station by a mobile trolley for subsequent operations.

[0012] After cleaning and assembly, reconnect the disassembly track and the lifting and moving part, and insert the lifting and moving part into the mounting slot on the mold head mounting plate for accurate positioning. Push the assembled mold head assembly back to the installation position along the track via the bearing assembly, and operate the lifting and moving part to descend, so that the groove at the bottom of the mold head assembly precisely engages with the boss on the mold head mounting plate. Finally, fix the mold head assembly to the mold head mounting plate, and disassemble the track and auxiliary components to complete the installation process.

[0013] Furthermore, the edge of the placement plate is surrounded by three sides, and the side of the mobile trolley is equipped with a push-pull handle.

[0015] Furthermore, the lifting and moving part includes a plug-in box, the end of which is provided with the mounting protrusion; the top of the plug-in box has an opening and a lifting block is slidably connected thereto, and the bottom of the lifting block is fixedly connected to an inclined plate; a rotating screw is disposed through the plug-in box, and the two ends of the rotating screw are rotatably connected to the side wall of the plug-in box through bearings; a trapezoidal block is fitted onto the rotating screw, and the upper surface of the trapezoidal block cooperates with the inclined surface of the inclined plate; when the rotating screw rotates and drives the trapezoidal block to move horizontally, the inclined plate drives the lifting block to move vertically.

[0016] Furthermore, a limiting block is detachably installed on the outer side of the lifting block, which is used to limit the range of movement of the bearing assembly.

[0017] Furthermore, a drive component is connected to the end of the rotating lead screw, which is either a ring-shaped rotating handle or a servo motor.

[0018] Furthermore, the bearing assembly includes a connecting block with symmetrically distributed mounting holes on its side, which is detachably connected to the side of the mold head assembly by bolts; the bottom of the connecting block is provided with a concave groove, in which at least one pair of rollers with bearings are installed, and the outer circumferential surface of the rollers forms rolling contact with the upper surface of the disassembly track.

[0019] Furthermore, one end of the positioning pin is provided with an anti-detachment handle, and the other end is provided with a limiting hole, into which a cotter pin can be inserted to prevent the positioning pin from accidentally falling off.

[0020] Furthermore, the placement plate is symmetrically provided with limit insertion holes, which are located on the moving path of the bearing assembly, and a blocking block is matched and installed on the top of the limit insertion hole.

[0021] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model is reasonably designed. By combining track sliding with a lifting mechanism, it achieves smooth transfer and precise positioning of the mold head assembly, effectively avoiding the safety hazards and accuracy deviations of traditional hoisting methods.

[0022] The use of a plug-in rail connection structure and an automatic centering and positioning design significantly improves the repeatability of mold head assembly and disassembly, ensuring consistency between product batches while reducing the labor intensity of operators.

[0023] The entire device has a reasonable structure and is easy to operate. It not only ensures operational safety but also improves production efficiency. It is especially suitable for high-precision die head assembly and disassembly operations that require high coating uniformity and thickness consistency.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] See attached document Figure 1-5 A safety assembly and disassembly structure for a precision mold head includes a mobile trolley 1, on the top of which is a placement plate 2 for supporting the mold head assembly 7; The disassembly track 3 is detachably mounted on one side of the mobile trolley 1; The lifting and moving part 4 is detachably connected to the other end of the disassembly and assembly track 3. The lifting and moving part 4 is configured to be inserted into a preset mounting slot on the mold head mounting plate 6 to achieve precise docking with the mold head mounting plate 6. The bearing assembly 5 is slidably disposed on the top of the lifting and moving part 4 and detachably installed on both sides of the mold head assembly 7 to be moved; The bottom of the mold head assembly 7 is symmetrically provided with positioning grooves that cooperate with the positioning bosses in the mold head mounting plate 6 to achieve automatic centering and positioning of the mold head assembly 7.

[0034] In this embodiment, when the die head assembly 7 needs cleaning or maintenance, one end of the disassembly track 3 is first connected to the moving trolley 1, and the other end is connected to the lifting moving part 4. The moving trolley 1 is pushed to accurately insert the lifting moving part 4 into the mounting slot, ensuring the initial alignment accuracy of the entire disassembly system with the coating machine body. In this embodiment, the die head mounting plate 6 is a partial structure of the coating machine; the coating machine is existing technology and will not be discussed further.

[0035] Subsequently, the bearing assembly 5 is installed on both sides of the mold head assembly 7 to be disassembled. The connecting bolts between the mold head assembly 7 and the mold head mounting plate 6 are loosened, and the lifting and moving part 4 is operated to lift upwards, separating the positioning groove at the bottom of the mold head assembly 7 from the positioning boss on the mold head mounting plate 6. At this time, the rollers of the bearing assembly 5 are flush with the upper surface of the disassembly and assembly track 3, and the operator can smoothly push the mold head assembly 7 along the track onto the placement plate 2 of the moving trolley 1.

[0036] After the mold head assembly 7 is removed, the disassembly and assembly rail 3 and the lifting and moving part 4 are disassembled, and the mold head assembly 7 is transferred to the cleaning station by the mobile trolley 1 for subsequent operations.

[0037] After cleaning and assembly, reconnect the disassembly track 3 to the lifting and moving part 4, and insert the lifting and moving part 4 into the mounting groove on the mold head mounting plate 6 for accurate positioning. Push the assembled mold head assembly 7 back to the installation position along the track via the bearing assembly 5, and operate the lifting and moving part 4 to descend, so that the groove at the bottom of the mold head assembly 7 precisely engages with the boss on the mold head mounting plate 6. Finally, fix the mold head assembly 7 to the mold head mounting plate 6, and disassemble the track and auxiliary components to complete the installation process.

[0038] This invention significantly improves the docking accuracy of the lifting and moving part 4 by setting an installation groove structure that matches the mold head mounting plate 6, thereby ensuring the repeatability and operational safety of the mold head assembly 7 during assembly and disassembly.

[0039] The placement plate 2 is equipped with three-sided enclosures 21 along its edge, and the mobile trolley 1 is equipped with push-pull handles 22 on its side. In this embodiment, the placement plate 2 of the mobile trolley 1 is equipped with a three-sided enclosure structure 21, which effectively prevents the mold head assembly 7 from accidentally slipping off the placement plate 2 during movement, thus improving the safety of the handling process. Simultaneously, push-pull handles 22 are fixedly installed on the side of the mobile trolley 1. This handle structure facilitates the operator in pushing the mobile trolley 1, allowing it to move flexibly between different workstations, greatly improving the convenience of assembly and disassembly operations.

[0040] The disassembly / assembly track 3 has an L-shaped structure with insertion protrusions 31 at both ends. The corresponding positions of the moving trolley 1 and the lifting moving part 4 have mounting protrusions 32 that mate with the insertion protrusions 31. The insertion protrusions 31 and the mounting protrusions 32 are detachably connected by positioning pins 33. In this embodiment, the disassembly / assembly track 3 adopts an L-shaped structure design to facilitate the limiting function of the bearing assembly 5. Both ends of the track have insertion protrusions 31. Correspondingly, mounting protrusions 32 are provided at corresponding positions on the moving trolley 1 and the lifting moving part 4. When connecting the tracks, align the insertion protrusions 31 at both ends of the track with the mounting protrusions 32 on the moving trolley 1 and the lifting moving part 4 respectively, and then insert the positioning pins 33 to achieve a secure connection.

[0041] This connection structure has the following advantages: First, the engagement of the insertion protrusion 31 and the mounting protrusion 32 provides initial positioning, facilitating the insertion of the positioning pin 33; second, the connection method of the positioning pin 33 ensures the stability of the track during use and can withstand the load generated when the mold head assembly 7 slides; finally, this connection structure enables quick assembly and disassembly of the track, simplifying the assembly and disassembly process and improving work efficiency. After the transfer of the mold head assembly 7 is completed, simply pull out the positioning pin 33 to separate the track from the moving trolley 1 and the lifting moving part 4, facilitating equipment storage and subsequent use.

[0042] The lifting and moving part 4 includes a plug-in box 41, with the mounting protrusion 32 at one end; the top of the plug-in box 41 has an opening and a lifting block 42 is slidably connected thereto, and the bottom of the lifting block 42 is fixedly connected to an inclined plate 43; a rotating screw 44 is disposed through the plug-in box 41, and the two ends of the rotating screw 44 are rotatably connected to the side wall of the plug-in box 41 through bearings; a trapezoidal block 45 is fitted onto the rotating screw 44, and the upper surface of the trapezoidal block 45 cooperates with the inclined surface of the inclined plate 43; when the rotating screw 44 rotates and drives the trapezoidal block 45 to move horizontally, the inclined plate 43 drives the lifting block 42 to move vertically. In this embodiment, when it is necessary to disassemble the mold head assembly 7, the rotating screw 44 is rotated to drive the trapezoidal block 45 to move horizontally. Under the action of the inclined plate, the inclined plate 43 drives the lifting block 42 to move upward, thereby lifting the bearing assembly 5 installed on both sides of the mold head assembly 7 until the upper surface of the lifting block 42 is flush with the disassembly track 3. At this time, the mold head assembly 7 can slide out smoothly along the track.

[0043] When installing the mold head assembly 7, push the mold head assembly 7 onto the lifting block 42 along the track via the bearing assembly 5, rotate the screw 44 in the opposite direction to move the trapezoidal block 45 back, and the lifting block 42 will descend accordingly, driving the mold head assembly 7 to move downward, so that the positioning groove at its bottom can be precisely engaged with the positioning boss on the mold head mounting plate 6, thus completing the positioning installation.

[0044] A limiting block 46 is detachably installed on the outer side of the lifting block 42. The limiting block 46 is used to limit the movement range of the bearing assembly 5. In this embodiment, the outer side of the lifting block 42 is provided with a detachable limiting block 46, which is higher than the top surface of the lifting block 42. When the lifting block 42 rises to be flush with the disassembly and assembly track 3, the limiting block 46 can effectively block the bearing assembly 5 that has slid to this position, preventing it from accidentally slipping off the lifting block 42 during operation.

[0045] The end of the rotating lead screw 44 is connected to a driving component, which is a ring-shaped rotating handle or a servo motor. In this embodiment, the end of the rotating lead screw 44 is equipped with a driving component, and in specific implementation, a ring-shaped rotating handle or a servo motor can be used.

[0046] When using a ring-shaped rotary handle, the operator can precisely control the rotation of the lead screw by manual rotation, thereby adjusting the height of the lifting block 42. This drive method has a simple structure, is intuitive to operate, and facilitates fine-tuning, which helps ensure the accuracy of the positioning of the mold head assembly 7.

[0047] When a servo motor is used as the drive component, the servo motor is connected to the plug-in box 41 via a connecting plate, enabling automatic control of the lifting process. The servo motor provides stable output torque and precise speed control, making the lifting action smoother and more reliable, while reducing the labor intensity of operators and improving the efficiency of disassembly and assembly operations.

[0048] The bearing assembly 5 includes a connecting block 51 with symmetrically distributed mounting holes 52 on its side, which are detachably connected to the side of the die head assembly 7 by bolts. The bottom of the connecting block 51 is provided with a concave groove 53, in which at least one pair of rollers 53 with bearings are installed. The outer circumferential surface of the rollers 53 forms rolling contact with the upper surface of the disassembly track 3. In this embodiment, the bearing assembly 5 is connected to the die head assembly 7 by bolts, which facilitates quick assembly and disassembly, maintenance and replacement. The rolling contact between the bearing and the track significantly reduces sliding friction, making the movement of the die head assembly 7 on the track more effortless and stable. The symmetrically distributed bearing arrangement effectively improves the load-bearing stability and prevents the die head assembly 7 from deflecting or jamming during movement.

[0049] When the die head assembly 7 needs to move along the track, multiple bearings of the bearing assembly 5 simultaneously contact the track surface, forming a stable rolling support system to ensure that the heavy die head assembly 7 can easily and smoothly complete the transfer operation.

[0050] One end of the positioning pin 33 is provided with an anti-detachment handle, and the other end has a limiting hole. A cotter pin can be inserted into the limiting hole to prevent the positioning pin 33 from accidentally falling off. In this embodiment, the positioning pin 33 adopts an anti-detachment design. One end of the positioning pin 33 is provided with an anti-detachment ring formed by an annular flange. This structure can provide initial axial limitation after the positioning pin 33 is inserted. The other end of the positioning pin 33 is machined with a radially penetrating limiting hole. After the positioning pin 33 is fully inserted into the corresponding hole of the insertion protrusion 31 and the mounting protrusion 32, a cotter pin can be installed in the limiting hole to form a reliable anti-detachment safety device.

[0051] The placement plate 2 is symmetrically provided with limiting insertion holes 23, which are located on the moving path of the bearing assembly 5. A blocking block 24 is fitted onto the top of each limiting insertion hole 23. In this embodiment, two sets of limiting insertion holes 23 are symmetrically machined on the placement plate 2, and these holes are arranged along the moving trajectory of the bearing assembly 5. When the mold head assembly 7 moves to the predetermined position on the placement plate 2 via the bearing assembly 5, the limiting block 46 can be inserted into the corresponding limiting insertion hole 23.

[0052] The limiting mechanism has the following technical advantages: the blocking block 24 inserted into the limiting insertion hole 23 can form a reliable physical barrier on both sides of the mold head assembly 7, effectively preventing the mold head assembly 7 from slipping off the placement plate 2 due to inertia or accidental collision during transportation, thus significantly improving the safety of the mold head assembly 7 during handling. At the same time, the blocking block 24 is detachable, so it does not affect the normal placement and removal of the mold head assembly 7 on the placement plate 2, balancing safety and ease of operation.

[0053] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
