[0040] Reference Figures 1-4 The splicing device is used to transport a film roll. The film roll includes a core 101 and a membrane 100 wound around it. The length of the core 101 is greater than the width of the membrane 100, so the axial ends of the core 101 are not covered by the membrane 100. Specifically, the splicing device is used to unload the film roll from the winding device. The winding device uses conical chucks to secure the film roll at both ends of the core 101. During unloading, the conical chucks of the winding device are released, cooperating with the splicing device, and the splicing device unloads the film roll from the winding device.

[0041] The roll-taking device includes a frame 1, a roll-taking assembly 3, a drive assembly, and a stopper 4. The frame 1 has a transport line extending along a first direction. Two roll-taking assemblies 3 are provided, spaced apart along a second direction. The first direction is perpendicular to the second direction. In this embodiment, both the first and second directions are parallel to a horizontal plane. Specifically, the first direction is the direction of movement of the diaphragm, and the second direction is the axial direction of the diaphragm.

[0042] The two take-up assemblies 3 are each used to support the winding core 101. The two take-up devices 3 support the winding core 101 from both ends, specifically providing support force to the outer peripheral wall of the winding core 101. The two take-up assemblies 3 are both capable of moving relative to the frame 1 in a first direction and a second direction. The drive assembly is disposed on the frame 1 and is used to drive the take-up assemblies 3 to move relative to the frame 1 in the first direction and the second direction. The drive assembly drives the take-up assemblies 3 to move relative to the frame 1 in the first direction, thereby enabling the take-up assemblies 3 to transport the winding core 101 and the diaphragm 100 along the conveyor line.

[0043] In addition, there are two limit blocks 4, which are respectively arranged on the two winding assemblies 3, and the two limit blocks 4 are used to respectively abut against the end faces of the core 101, thereby limiting the core 101 along its axial direction. This can ensure that when the chuck of the winding device releases the film roll, the film roll is fixed from both ends of the core 101, so that the film roll can be smoothly detached from the chuck, preventing the film roll from axially moving and causing unloading failure. The drive assembly can also drive the winding assembly 3 to move in the second direction relative to the frame 1. On the one hand, it can change the spacing between the two winding assemblies 3 to adapt to the different lengths of the core 101. On the other hand, it can change the distance between the two limit blocks 4 so that the spacing between the two limit blocks 4 adapts to the axial length of the core 101, so that the two limit blocks 4 respectively abut against the end faces of the core 101, thereby limiting the core 101.

[0044] Continue to refer to Figures 1-4 The roll-taking device also includes two alignment components 2 slidably arranged on the frame 1 along the first direction, the two alignment components 2 are spaced apart along the second direction, the two alignment components 2 are arranged in one-to-one correspondence with the two roll-taking components 3, and the roll-taking components 3 are slidably connected to the alignment components 2 along the second direction. By controlling the alignment components 2 to slide relative to the frame 1 along the first direction, and controlling the roll-taking components 3 to slide relative to the alignment components 2 along the second direction, the roll-taking components 3 can move relative to the frame 1 along the first direction and the second direction.

[0045] Specifically, the drive assembly includes a first drive member 51 disposed on the frame 1 and a second drive member 52 disposed on the alignment assembly 2. The first drive member 51 is used to drive the alignment assembly 2 to reciprocate in a first direction relative to the frame 1, and the second drive member 52 is used to drive the take-up assembly 3 to reciprocate in a second direction relative to the alignment assembly 2. Thus, the first drive member 51 and the second drive member 52 cause the take-up assembly 3 to move in the first and second directions relative to the frame 1, respectively. The first drive member 51 is used to enable the take-up assembly 3 to transport the winding core 101 and the diaphragm 100 along the conveyor line. The second drive member 52 is capable of changing the spacing between the two take-up assemblies 3 to accommodate winding cores 101 of varying lengths. Furthermore, the second drive member 52 is capable of changing the distance between the two stoppers 4, adapting the spacing between the two stoppers 4 to the axial length of the winding core 101, so that the two stoppers 4 abut against the end faces of the winding core 101, thereby limiting the position of the winding core 101.

[0046] Continue to refer to Figures 1-4 The specific transmission connection between the first driving member 51 and the positioning assembly 2 is as follows: the first driving member 51 is a rodless cylinder, and the output end of the first driving member 51 is connected to a transmission block 511. The positioning assembly 2 has a groove, and the transmission block 511 is disposed in the groove and is used to drive the positioning assembly 2. In addition, the second driving member 52 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod.

[0047] Continue to refer to Figures 1-4 The frame 1 includes a first guide rail 11 extending in a first direction, and the alignment assembly 2 slidably engages with the first guide rail 11, thereby further stabilizing the sliding connection between the alignment assembly 2 and the frame 1; and / or the alignment assembly 2 includes a second guide rail 21 extending in a second direction, and the roll-taking assembly 3 slidably engages with the second guide rail 21, thereby further stabilizing the sliding connection between the roll-taking assembly 3 and the alignment assembly 2. This embodiment provides a solution in which both the first guide rail 11 and the second guide rail 21 are provided.

[0048] Continue to refer to Figures 1-4The winding assembly 3 includes a winding assembly base 31 slidably connected to the alignment assembly 2 and a support member 32 vertically slidably disposed on the winding assembly base 31. The support member 32 is used to support the winding core 101. Optionally, the winding device further includes a third driving member 53 disposed on the winding assembly base 31. The third driving member 53 is used to drive the support member 32 to reciprocate vertically relative to the winding assembly base 31, thereby adjusting the height of the support member 32 relative to the winding assembly base 31. Before being conveyed to the winding device provided in this embodiment, the diaphragm 100 and the winding core 101 are typically clamped and fixed by a chuck. By making the height of the support member 32 adjustable relative to the winding assembly base 31, it can accommodate different chuck heights. Furthermore, the third driving member 53 can be a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. In this embodiment, it is a pneumatic cylinder. This arrangement can also provide a certain degree of cushioning after the winding core 101 falls onto the support member 32.

[0049] Continue to refer to Figures 1-4 The roll-joining assembly base 31 is provided with a vertical guide rail 311 extending in the vertical direction, and the support member 32 slides with the vertical guide rail 311, thereby making the sliding connection between the roll-joining assembly base 31 and the support member 32 more stable.

[0050] Continue to refer to Figures 1-4 The support member 32 has a support groove 321, the groove wall of the support groove 321 is used to support the core 101, and the groove wall of the support groove 321 is V-shaped, so as to prevent the core 101 from falling from the support member 32 during transportation, and the outer walls of the cores 101 of different diameters can respectively abut against the two side walls of the support groove 321 and remain fixed relative to the support member 32.

[0051] As an alternative, the groove wall of the support groove 321 is arc-shaped, that is, the support groove 321 is an arc-shaped groove, which can also prevent the core 101 from falling off the support member 32 during transportation. However, it can only adapt to the core 101 of a specific diameter. If the diameter of the core 101 is small, it may cause the core 101 to roll relative to the support member 32 during transportation. If the diameter of the core 101 is large, the support may be unstable.

[0052] Continue to refer to Figures 1-4The winding device also includes a limit block driver 6 provided on the winding assembly base 31. The limit block 4 is connected to the limit block driver 6. The limit block driver 6 is used to drive the limit block 4 to reciprocate relative to the winding assembly base 31 along the second direction. Such a configuration can adapt to winding cores 101 of different lengths. The limit block driver 6 is a cylinder, and the use of a cylinder can also play a buffering role. Before placing the winding core 101, the distance between the two limit blocks 4 is increased to facilitate the placement of the winding core 101 and the diaphragm 100 to prevent interference. After preventing the winding core 101, the limit block driver 6 drives the limit block 4 to move, so that the two limit blocks 4 are respectively abutted against the end faces of the two ends of the winding core 101 to achieve limiting.

[0053] Continue to refer to Figures 1-4 The roll-receiving device also includes a support base 10, which is used to support the ground and to support the frame 1, so that the frame 1 is installed on the ground. Specifically, there are two frames 1, and the two alignment components 2 are arranged in a one-to-one correspondence on the two frames 1. Each frame 1 is supported by at least three support bases 10 to ensure the stability of the support.

[0054] The working principle of the roll-receiving device of this embodiment is as follows:

[0055] The winding device uses a conical chuck to fix the film roll from both ends of the roll core 101. When the roll needs to be unloaded, the controller sends an unloading instruction to the roll receiving device. After receiving the unloading instruction, the roll receiving device drives the roll receiving assembly 3 to a preset position through the first drive member 51 and the second drive member 52; then the third drive member 53 drives the roll receiving assembly 3 to move upward; the limit block drive member 6 drives the limit block 4 to move in the second direction, so that the two limit blocks 4 respectively abut against the two end portions of the roll core; then, the chuck of the winding device releases the roll core, and the film roll falls onto the support member 32. At this time, the first drive member 51 can be used to drive the alignment assembly 2 to move relative to the frame 1 in the first direction, so that the film roll can be transported on the frame 1 along the first direction.

[0056] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
