Description

Technical Field

[0001] This utility model relates to the field of refrigerator manufacturing technology, and in particular to an automatic film-cutting device for refrigerator door panels. Background Technology

[0002] In the current booming refrigerator manufacturing industry, market demand for refrigerators is increasingly characterized by diversification and higher quality. On the one hand, consumers not only pursue superior cooling and preservation performance but also place higher expectations on the aesthetics and uniqueness of refrigerator designs. This has prompted refrigerator manufacturers to continuously innovate, with innovative designs such as curved glass doors and embedded handles emerging, greatly enriching the product's appearance. On the other hand, with the deepening popularization of intelligent manufacturing concepts, refrigerator manufacturers are actively seeking effective ways to improve production efficiency and reduce production costs in order to stand out in the fierce market competition and achieve large-scale, refined production.

[0003] Against this industry backdrop, the manufacturing process of refrigerator door panels faces severe challenges. As a key component directly facing consumers throughout the refrigerator production process, the surface quality of the refrigerator door panel directly impacts the overall product image. To prevent scratches, contamination, or corrosion during production, transportation, and assembly, a protective film is typically applied to the door panel surface, commonly made of PE or PET. However, traditional methods of using protective films have many drawbacks. In subsequent processing stages, such as installing handles, hinges, displays, or affixing labels, the protective film in specific areas of the door panel needs to be treated. Previously, this was mainly done by workers manually peeling off portions of the protective film, but this method has significant flaws. Manual operation is not only extremely inefficient, making it difficult to meet the pace of large-scale, high-efficiency production, but also, due to the variability in manual operation, it is highly susceptible to irreversible damage to the door panel caused by improper control of force and angle, such as scratches and dents, thus affecting the product's appearance quality and yield rate. Furthermore, manually peeling off the protective film often results in residue, which can interfere with subsequent processes such as spraying and bonding, leading to reduced coating adhesion and loose bonding. In addition, the edges of manually peeled film are often uneven, a defect that is unacceptable for modern refrigerators that strive for a refined appearance.

[0004] Taking the patent "CN211336746U, a blade-based automatic scribing mechanism for refrigerator side panels" as an example, this patent uses a scribing mechanism composed of blades, support rods, and counterweights. The scribing depth is adjusted by the number of counterweights. While this solves some of the problems of high cost, the need for uniform scribing speed, and inconvenient replacement associated with traditional soldering iron scribing mechanisms, the device still has shortcomings in scribing accuracy and adaptability to complex door panel shapes, making it difficult to meet the diverse design needs of modern refrigerator doors. For example, for scribing curved glass doors, this mechanism cannot achieve precise curved scribing, failing to meet production requirements. Utility Model Content

Unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all within the protection scope of the present invention.

[0029] Example 1

[0030] Please see Figure 1 This utility model provides an automatic film-splitting device for refrigerator door panels. During the refrigerator manufacturing process, the surface of the refrigerator door panel is usually covered with a protective film (such as PE or PET material) to prevent scratches, contamination or corrosion during production, transportation and assembly.

[0031] However, because door panels require localized processing in specific areas (such as where handles, hinges, displays, or labels are installed), workers often need to manually peel off parts of the protective film. This process is not only inefficient but also prone to damage to the door panel, residual protective film, or uneven edges due to improper handling, which in turn affects subsequent painting, bonding processes, or the final product's appearance quality.

[0032] Therefore, automated film-cutting technology has emerged, which uses mechanical cutting or laser marking technology to precisely mark the peeling area on the protective film, enabling workers to quickly and neatly remove the designated part of the protective film.

[0033] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, the film-cutting device includes a pickup device 100 and a worktable. The pickup device 100 includes a first pickup part 140 and a second pickup part 150 disposed on a movable frame 120. The first pickup part 140 and the second pickup part 150 simultaneously perform pickup or placement actions on the refrigerator door panel 300 to realize the loading or unloading operation of the refrigerator door panel 300. The worktable includes a feeding platform 210, a first film-cutting platform 220, and a film-cutting mechanism disposed on the first film-cutting platform 220. The film-cutting mechanism includes a film-cutting gun 227, which can move based on the longitudinal and / or transverse directions of the film-cutting platform. The two ends of the pickup device 100 cover the entire working range of the worktable. The refrigerator door panel 300 is covered with a protective film, and the film-cutting mechanism uses the film-cutting gun 227 to partially cut the protective film on the refrigerator door panel 300.

[0034] In operation, several refrigerator door panels 300 that need to be scribed are first stacked on the feeding table 210. The first picking part 140 and the second picking part 150 of the picking device 100 work together to smoothly pick up the refrigerator door panels 300 and place them on the first scribe table 220. At this time, the scribe mechanism is activated, and the scribe gun 227 moves in the longitudinal and transverse directions of the scribe table according to the preset scribe trajectory to precisely cut the protective film on the refrigerator door panels 300. After the cutting is completed, the picking device 100 works again to pick up the cut refrigerator door panels 300 from the first scribe table 220 and put them down to the designated position. This facilitates the worker to quickly and neatly peel off the protective film of the designated part, greatly improving the efficiency and quality of film peeling during the processing of refrigerator door panels 300 and reducing various problems caused by manual operation.

[0035] Further, please see Figure 1 and Figure 2The pickup device 100 further includes at least two support columns 110 and a movable frame 120 disposed on the top of the support columns 110. The movable frame 120 has a sliding groove 121 inside, with a first rotating seat 122 and a second rotating seat 123 respectively disposed at both ends of the sliding groove 121. The first rotating seat 122 and the second rotating seat 123 are connected by a belt 124. The first rotating seat 122 is driven by a pickup motor. The sliding groove 121 has a first guide rail 125 and a second guide rail 126 respectively disposed on the side of the belt 124. A movable seat 127, movable based on the first guide rail 125 and the second guide rail 126, is disposed on the first guide rail 125 and the second guide rail 126 via a slider. The movable seat 127 is fixedly connected to one side of the belt 124. The sliding groove 121 has limiting posts 128 at both ends of the first guide rail 125 and the second guide rail 126 to limit the stroke of the slider. The movable seat 127 is provided with a first pickup part 140 and a second pickup part 150 at intervals via a mounting crossbar 130; the first pickup part 140 includes an extension rod 141 connected to the mounting crossbar 130 and a pickup cylinder 142 connected to the extension rod 141; the bottom of the pickup cylinder 142 is provided with a mounting plate 143 for mounting a pickup suction cup 144.

[0036] In use, the pickup motor is started, driving the first rotating seat 122 to rotate, which in turn drives the movable seat 127 to move along the first guide rail 125 and the second guide rail 126 within the slide groove 121 via the belt 124. During the movement of the movable seat 127, the first pickup section 140 and the second pickup section 150, which are spaced apart on it, also move accordingly. When it reaches the appropriate position, the pickup cylinder 142 of the first pickup section 140 is activated, pushing the mounting plate 143 downwards, causing the pickup suction cup 144 to contact the object to be picked up (refrigerator door panel 300), and using suction to pick up the object. Afterwards, the pickup motor reverses, driving the movable seat 127 to move in the opposite direction, transporting the picked-up object to the designated position. Then, the pickup cylinder 142 is driven again, causing the pickup suction cup 144 to separate from the object, completing one pickup action. If multiple pickups are required, the above steps can be repeated. The second pickup section 150 can also be used to perform pickup operations synchronously or sequentially, improving pickup efficiency and meeting different work requirements.

[0037] In this embodiment, the precise and stable linear motion of the moving seat 127 is achieved through the transmission of the motor and belt 124, combined with the cooperation of the guide rail and the slider, ensuring that the picking unit can accurately reach the position of the object to be picked up. The setting of the limiting post 128 effectively prevents the slider from derailing, ensuring the safety and reliability of the device operation. The spacing between the first picking unit 140 and the second picking unit 150 allows them to cooperate in picking operations, greatly enhancing the flexibility and applicability of the picking device 100, thereby effectively improving overall work efficiency, reducing labor costs, and providing strong support for production automation.

[0038] Please see Figure 1 , Figure 4 and Figure 5 The workbench also includes a second cutting platform 230; the mounting crossbar 130 is also provided with a third picking-up part 160 corresponding to the second cutting platform 230; wherein the first picking-up part 140, the second picking-up part 150 and the third picking-up part 160 have the same structural configuration. By setting two cutting platforms (first cutting platform 220 and second cutting platform 230) and a feeding platform 210, as well as three picking-up parts (first picking-up part 140, second picking-up part 150 and third picking-up part 160) adapted to these workbench, material feeding and cutting and discharging can be realized simultaneously, or longitudinal or transverse cutting operations can be realized on the two feeding platforms.

[0039] In operation, the pickup motor is activated, driving the first pickup unit 140, the second pickup unit 150, and the third pickup unit 160 to pick up refrigerator door panels 300 from different workstations. Simultaneously, the work includes moving the refrigerator door panel 300 from the feeding table 210 to the first cutting table 220, moving the door panel from the first cutting table 220 to the second cutting table 230, and moving the refrigerator door panel 300 from the second cutting table 230 to the discharge area. By repeating these actions, the entire process of feeding, cutting, and discharging the refrigerator door panel 300 can be completed continuously and efficiently. The coordinated work of multiple pickup units further improves work efficiency and reduces the time wasted by frequent switching between different workstations by a single pickup unit.

[0040] Moreover, the identical structure of the three pickup sections makes maintenance and replacement of parts more convenient, reducing equipment maintenance costs and difficulty. This design not only optimizes the production process but also makes the entire device more stable and reliable, providing a strong guarantee for the efficient production of refrigerator door panels 300, and has significant advantages and application value in actual production scenarios.

[0041] Further, please see Figure 3The feeding platform 210 includes a placement area 212 disposed on the top of the work frame 211 and a limiting mechanism 214 for limiting the position of the refrigerator door panel 300 in the placement area 212; a displacement track 213 is disposed on the top of the work frame 211, and the limiting mechanism 214 can move based on the displacement track 213.

[0042] The limiting mechanism 214 can move automatically (e.g., using a cylinder) along the displacement track 213 to accommodate the placement needs of refrigerator door panels 300 of different sizes. When a larger refrigerator door panel 300 needs to be placed, the operator can move the limiting mechanism 214 outward along the displacement track 213 to expand the placement area 212; while when placing a smaller refrigerator door panel 300, the limiting mechanism 214 is moved inward so that the refrigerator door panel 300 can be accurately limited within the placement area 212, preventing it from shifting position during subsequent picking, thereby ensuring the accuracy and stability of the entire production process. This movable limiting mechanism 214 design greatly enhances the versatility and adaptability of the feeding platform 210, laying a solid foundation for the efficient production of refrigerator door panels 300 of different specifications.

[0043] Further, please see Figure 4 A first displacement mechanism is provided via the movable guide rail. The first film-cutting platform 220 includes a base 221, and the first displacement mechanism can move longitudinally along the base 221. A second displacement mechanism is also provided via the first displacement mechanism, which can move laterally along the base 221. The film-cutting gun 227 is disposed on the second displacement mechanism. The surface of the base 221 is configured as a working surface 222. Limiting rods 224 and movable guide rails disposed on the limiting rods 224 are provided on both sides of the top of the base 221.

[0044] Furthermore, the movement also includes a limiting device for the refrigerator door panel 300. During the film-cutting process, this device maintains the stability of the refrigerator door panel 300's position and prevents displacement that could affect the cutting accuracy. This limiting device can be flexibly adjusted according to the size and shape of the refrigerator door panel 300, ensuring a reliable limiting effect in film-cutting operations for refrigerator door panels 300 of different specifications.

[0045] The limiting device includes a first limiting part 241, a third limiting part, and a second limiting part 242 disposed at the end of the base 221; the first limiting part 241 is disposed at the top of the base 221, and the third limiting part is disposed at the bottom of the working surface 222; the first limiting part 241, the second limiting part 242, and the third limiting part are all provided with corner limiting blocks 243; the corner limiting blocks 243 of the first limiting part 241 are disposed on the moving rod, and the corner limiting blocks 243 of the second limiting part 242 are disposed on the guide rail at the end of the base 221, and all of them can move, and their movement can be achieved by setting a cylinder.

[0046] In use, the refrigerator door panel 300 is placed on the working surface 222 by the pickup part. At this time, the refrigerator door panel 300 is first pushed to the end of the base 221 by the first limiting part 241 so that it abuts against the end of the base. Then, the other end of the refrigerator door panel 300 is limited by the corner limiting block 243 to limit the refrigerator door panel 300. When performing the slicing operation, if the required slicing position does not exceed the expected processing position, it can be limited by the corner limiting block 243 of the first limiting part 241 and the second limiting part 242 set on the top of the base 221. If the required slicing position may exceed the expected processing position, the movement of the slicing gun 227 may be limited by the first limiting part 241. Therefore, it is limited by the third limiting part set at the bottom of the working surface 222.

[0047] Furthermore, the second marking stage 230 has the same mechanism as the first marking stage 220.

[0048] Furthermore, the scribing gun 227 is either a laser gun or a thermal welding gun. The advantages of both laser guns and thermal welding guns are that laser guns have the characteristics of high precision and non-contact scribing, which can achieve fine scribing lines. They are suitable for scribing refrigerator door panels 300, which have extremely high precision requirements, and will not cause physical damage to the surface of the door panel, thus maintaining the integrity of the door panel's appearance.

[0049] The hot welding gun excels in connection strength. By melting the material at high temperatures during the scribing process, it achieves high bonding strength at the scribing points, making it particularly suitable for the scribing requirements of refrigerator door panels 300, which demand strong structural connections. In practical applications, the choice between a laser gun or a hot welding gun can be flexibly made based on factors such as the material of the refrigerator door panel 300, the specific scribing requirements, and the manufacturing process to achieve the best scribing effect and production efficiency.

[0050] Example 2

[0051] Please see Figure 4 and Figure 5This utility model provides an automatic film-cutting device for refrigerator door panels. In the context of diverse designs of refrigerator door panels, such as curved glass doors and embedded handles, traditional manual film tearing and existing automated film-cutting devices have the problem of not being able to achieve precise curved film cutting in complex shape areas, which makes it difficult to meet the needs of high-precision production.

[0052] In Embodiment 1, the first displacement mechanism and the second displacement mechanism can realize the transverse displacement of the refrigerator door panel 300 based on the longitudinal displacement. At this time, the distance between the scribing gun 227 and the refrigerator door panel 300 is constant, so it can only scribing the flat refrigerator door panel 300. For curved door panels, uneven scribing and inconsistent depth may occur.

[0053] This embodiment 2 addresses this issue by adding a distance adjustment mechanism to the first and second displacement mechanisms. This distance adjustment device can monitor the distance between the scribing gun 227 and the surface of the curved refrigerator door panel 300 in real time, ensuring that the scribing gun 227 can always maintain a suitable distance for accurate scribing regardless of the curved shape of the refrigerator door panel 300.

[0054] Therefore, in this embodiment, a third displacement mechanism is also provided, which can move along the vertical direction of the base 221 based on the second displacement mechanism. The third displacement mechanism includes a second mounting block 228 provided by a slide rail provided on the first mounting block 226, and the slicing gun 227 is provided on the second mounting block 228; and a sensor for detecting the distance from the surface of the refrigerator door panel 300 is provided.

[0055] In use, the first and second displacement mechanisms are activated first, allowing the device to move laterally and longitudinally along a preset path on the refrigerator door panel 300. Simultaneously, the sensors begin working, continuously feeding back distance data between the scribing gun 227 and the surface of the refrigerator door panel 300. If a change in distance is detected, the third displacement mechanism, based on the sensor data, moves the scribing gun 227 along the vertical direction of the base 221 via the movement of the second mounting block 228 on the second guide rail 227. This allows the scribing gun 227 to move closer to or further away from the refrigerator door panel 300, ensuring that the scribing gun 227 adjusts its position promptly and maintains the preset scribing distance from the curved refrigerator door panel 300.

[0056] Thus, the scribing gun 227 can ensure uniform scribing and consistent depth during the scribing process of curved refrigerator door panel 300, effectively solving the problem of precise curved scribing in complex shape areas, greatly meeting the needs of high-precision production, and improving the production quality and efficiency of refrigerator door panel 300.

[0057] In this embodiment, the automatic film-cutting device for refrigerator door panels effectively overcomes the challenge of curved film cutting through its structural design. Pickup device 100

[0058] The design employs a movable frame 120 with multiple pickup units (first pickup unit 140, second pickup unit 150, and third pickup unit 160), which can flexibly adjust the position, accurately grab the refrigerator door panel 300, and transfer it to the designated workstation, providing a stable and precise positioning foundation for the film-cutting operation. The worktable is equipped with a feeding platform 210, a first film-cutting platform 220, and a second film-cutting platform 230. The limiting mechanism 214 of the feeding platform 210 can move along the displacement track 213 to ensure that the position of the door panel in the placement area 212 is accurately controllable. The surface of the base 221 of the film-cutting platform serves as the working surface 222. The moving guide rails on both sides, in conjunction with the multi-stage displacement mechanism, can drive the film-cutting gun 227 to move flexibly in the longitudinal and transverse directions of the base 221. Whether it is the curved contour of a curved glass door or the irregular area of ​​an embedded handle, the film-cutting gun 227 can strictly follow the preset program to perform high-precision curved film-cutting operations. This structure, which combines precise positioning with flexible movement, along with advanced scribing technologies such as laser or thermal welding, achieves millimeter-level precision scribing for complex shaped areas. This completely solves the problem that traditional methods cannot accurately scribing curved areas, significantly improving scribing efficiency and production quality, and meeting the high-precision production requirements of modern refrigerators with diverse designs.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
