[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all the embodiments.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof mean "at least comprising."
[0028] To address the technical problem of the cumbersome winding process of the Hirano casting machine and the potential damage to the film roll during the process, or to achieve at least one or more of the aforementioned advantages, an embodiment of this utility model provides an MLCC casting film roll take-up device. This MLCC casting film roll take-up device includes a forklift (not fully shown in the figure) and an MLCC casting film roll transfer cart 100.
[0029] like Figure 1 As shown, the MLCC cast film roll transfer cart 100 includes a cart body 10. The cart body 10 is made entirely of stainless steel, providing good rigidity and support. Preferably, the cart body 10 is made of 316 stainless steel, which offers better corrosion resistance.
[0030] The upper surface of the vehicle body 10 is designed with a placement groove 20 for placing the cast film roll 200. The placement groove 20 can be a smooth arc-shaped groove, which fits the surface of the cast film roll 200 better, and the smooth surface can avoid damage to the cast film roll 200. The four corners of the placement groove 20 are designed with smooth rounded corners to improve the yield and reduce production costs.
[0031] Furthermore, due to the high hardness of stainless steel, a buffer layer 21 can be provided on the surface of the placement groove 20. This can reduce damage and deformation caused by gravity impact when the cast film roll 200 falls. Preferably, the buffer layer 21 can be laid with silicone or rubber with a thickness of 1 cm. Of course, the thickness of the buffer layer 21 can also be adjusted according to actual needs, or other soft and elastic materials can be used for laying, without limitation.
[0032] Of course, the surface of the buffer layer 21 can also be designed as a smooth surface.
[0033] Please combine Figure 1 See Figure 2 The lower surface of the vehicle body 10 is provided with a pulley assembly 30. This allows the MLCC cast film roll transfer cart 100 to move. During the actual material collection process, the cast film roll 200 is placed in the placement slot 20, and the MLCC cast film roll transfer cart 100 is moved to the vicinity of the dedicated film roll rack. Then, a forklift is used to pick up and properly place the film roll.
[0034] In a specific implementation, the pulley assembly 30 includes a first wheel group 31 and a second wheel group 32. The first wheel group 31 and the second wheel group 32 are arranged horizontally at intervals from front to back in the direction of travel of the MLCC cast film roll transfer cart 100. Preferably, the first wheel group 31 are directional wheels. The second wheel group 32 are omnidirectional wheels, which facilitates control of the direction of travel of the MLCC cast film roll transfer cart 100 during movement.
[0035] The lower surface of the vehicle body 10 can also be designed with a first slide groove 40 and a second slide groove 50 that are symmetrical to each other. In the specific material receiving process, the forklift feet 300 can be inserted into the first slide groove 40 and the second slide groove 50 to pick up and drop the cast film roll 200.
[0036] It is understood that the forklift mentioned in this embodiment is the forklift commonly used in the current commercial film roll take-up process, and its structure and principle are common knowledge and are not within the scope of protection of this application. Based on this, the MLCC cast film roll transfer vehicle 100 described in this embodiment can also be applied to the take-up process of other types of casting machines to improve take-up efficiency and reduce the possibility of damage to the film roll during take-up.
[0037] Based on the above, a depth locking mechanism 60 can also be designed on the lower surface of the vehicle body 10. The depth locking mechanism 60 protrudes from the side wall of the first slide groove 40 and / or the second slide groove 50. In specific implementation, there can be two depth locking mechanisms 60, which are respectively arranged on the left and right sides of the lower surface of the vehicle body 10, and protrude from the side wall of the first slide groove 40 and the side wall of the second slide groove 50 respectively.
[0038] The depth locking mechanism 60 can limit the insertion depth of the foot 300 into the vehicle body 10, thereby limiting the distance between the forklift and the MLCC cast film roll transfer vehicle 100. This allows the forklift's fork rollers to be inserted into the film roll tube 201 of the cast film roll 200 but not to extend from the other end. This facilitates the connection between the cast film roll 200 and the insertion rollers on the dedicated film roll rack during the subsequent placement of the cast film roll 200, improving the stability of the cast film roll 200 during the transfer to the dedicated film roll rack and preventing slippage or damage to the cast film roll 200 by the insertion rollers of the dedicated film roll rack.
[0039] In some preferred embodiments, such as Figure 3As shown, the depth locking mechanism 60 includes a roller 61. The roller 61 is laterally and rotatably disposed on the lower surface of the vehicle body 10. The roller 61 protrudes from the sidewalls of the first slide groove 40 and the second slide groove 50. The roller 61 is provided with a first opening 611.
[0040] by Figure 3 Taking the direction shown as an example, when the foot 300 is inserted downward into the first groove 40 and the second groove 50, as the depth increases, the foot 300 abuts against the lower side wall of the first opening 611 and drives the roller 61 to rotate clockwise.
[0041] When the upper sidewall of roller 61 contacts foot 300, roller 61 stops rotating due to space constraints caused by protruding from the sidewalls of the first slide groove 40 and the second slide groove 50, thus blocking foot 300. This controls the distance between the forklift and the MLCC cast film roll transfer cart 100, allowing the forklift's fork rollers to insert into the film roll tube 201 of the cast film roll 200 but not protrude from the other end. This facilitates the subsequent placement of the cast film roll 200 with the insertion rollers on the dedicated film roll rack, improving the stability of the cast film roll 200 during transfer to the dedicated film roll rack and preventing slippage or damage to the cast film roll 200 by the insertion rollers of the dedicated film roll rack.
[0042] In another modified embodiment, the depth locking mechanism 60 further includes a locking pin 62. The locking pin 62 is movably disposed on the lower surface of the vehicle body 10 and is in a retractable state with respect to the vehicle body 100 by a spring (not shown). The roller 61 has a second opening 612 spaced apart from the first opening 611. The locking pin 62 is movably connected to the second opening 612.
[0043] In specific implementation, such as Figure 4 and Figure 5 As shown, the first opening 611 and the second opening 612 are spaced apart from each other along the circumference of the roller 61. The first sidewall 6121 of the second opening 612 is a long sloping design, and the second sidewall 6122 is a steep slope design relative to the center of the roller 61. When the roller 61 rotates, the locking pin 62 slides on the first sidewall 6121. When the locking pin 62 engages with the second sidewall 6122, the roller 61 stops rotating.
[0044] Specifically, with Figure 4 Taking the direction shown as an example, when the foot 300 is inserted downward into the first slide groove 40 and the second slide groove 50, as the depth increases, the foot 300 abuts against the lower side wall of the first opening 611, and drives the roller 61 to rotate clockwise, causing the locking pin 62 to slide to the left along the direction of the first side wall 6121 and extend downward relative to the vehicle body 10. When the locking pin 62 engages with the second side wall 6122, the roller 61 stops rotating.
[0045] At this time, the roller 61 can apply friction to the foot 300 to intercept the foot 300 and control the distance between the forklift and the MLCC casting film roll transfer cart 100. Preferably, a protrusion 63 can be provided between the first opening 611 and the second opening 612. This can prevent the roller 61 from rotating counterclockwise and causing the locking pin 62 to insert into the first opening 611, and can also increase the contact area between the roller 61 and the foot 300, thereby increasing the friction.
[0046] In some preferred embodiments, the surface of the roller 61 may be provided with a friction layer 64 to increase friction. The friction layer 64 does not cover the second opening 612.
[0047] In summary, the MLCC cast film roll transfer cart and receiving device provided by this utility model, compared with the prior art, uses an MLCC cast film roll transfer cart to place the film rolls taken from the casting machine, reducing the possibility of damage to the film rolls caused by other rough surfaces. At the same time, a depth locking mechanism is set on the lower surface of the cart body to limit the insertion depth of the forklift during cooperation, which facilitates the proper placement of the film rolls with the dedicated film roll rack after the forklift inserts the film rolls, thereby improving the receiving efficiency.
[0048] Although this document uses terms such as vehicle body and placement slot frequently, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
