[0021] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0022] Please refer to Figures 1-4 As shown in the preferred embodiment of this application, a tape splicing feeding device includes a feeding component 1, a tray component 2, a pressing component 3, a cutting component 4, a splicing component 5, a power pulling component 6, and a storage component 7. The feeding assembly 1 includes at least two feeding trays for winding the tape. The feeding assembly 1 can move along a first direction under external force so that one of the feeding trays can supply material. A tray assembly 2 is disposed on one side of the feeding assembly 1 along a second direction for supporting the tape. The first direction is perpendicular to the second direction. A clamping assembly 3 is disposed on the feeding assembly 1 and can move relative to the feeding assembly 1 under external force to clamp the tape on the tray assembly 2. A cutting assembly 4 is disposed below the tray assembly 2 for cutting the tape clamped by the clamping assembly 3. A connecting assembly 5 is disposed above the tray assembly 2 for connecting the head and tail ends of the tape wound by the two feeding trays. A power-driven material-pulling assembly 6 is disposed on one side of the tray assembly 2 along the second direction for providing power to convey the tape. A storage assembly 7 is disposed on one side of the power-driven material-pulling assembly 6 along the second direction for storing a certain length of tape.

[0023] Understandably, by providing at least two feed trays and allowing the feeding assembly 1 to move along a first direction, when the tape in one feed tray is exhausted, it is possible to seamlessly switch to the other feed tray. The connecting assembly 5 connects the beginning and end of the tape in the two feed trays to continue feeding. Furthermore, during the time that the connecting assembly 5 connects the beginning and end of the tape in the two feed trays, the storage assembly 7 stores enough tape to continue feeding during the connection time, thereby achieving continuous production without stopping the machine and improving production efficiency.

[0024] Furthermore, the pallet assembly 2 includes a pallet plate 21, which is provided with a guide groove for the tape to pass through, thereby enabling precise guidance of the tape and ensuring that the tape will not deviate or flip during the feeding process, thus improving the stability of the tape conveying. On the other hand, the guide groove can also provide a clear operating position for the subsequent connecting assembly 5 and cutting assembly 4, so that the head and tail ends of the tape can be accurately connected by the connecting assembly 5, and the cutting assembly 4 can also cut in the correct position, improving the accuracy and reliability of the operation.

[0025] In this embodiment, the guide groove includes at least a first guide groove 211 arranged along a first direction, a second guide groove 212 located on both sides of the first guide groove 211, and a third guide groove 213; the feeding assembly 1 has a first state and a second state; in the first state, the tape of one feeding tray passes through the first guide groove 211 for feeding, and the tape of the other feeding tray is located in the second guide groove 212 or the third guide groove 213; in the second state, the tail end of the tape of one feeding tray and the head end of the tape of the other feeding tray are both located in the first guide groove 211 so as to be pressed and connected by the connecting assembly 5.

[0026] Understandably, dividing the guide groove into a first guide groove 211, a second guide groove 212, and a third guide groove 213 allows for the simultaneous accommodation of tape from multiple feed trays, providing greater flexibility for the switching of the feeding assembly 1 and enabling a smooth transition between the first and second states. In the first state, tape from one feed tray is fed through the first guide groove 211, while tape from the other feed tray is positioned in the second or third guide groove 213 for standby. In the second state, the beginning and end ends of tape from both feed trays are located within the first guide groove 211, facilitating connection operations by the connecting assembly 5, optimizing the feeding switching process, and further improving the continuity and reliability of the feeding.

[0027] It is worth noting that, in this embodiment, for ease of description, the two feed trays are respectively defined as the first feed tray 11 and the second feed tray 12. When the tape of the first feed tray 11 is fed in the first guide groove 211, the second feed tray 12 corresponds to the second guide groove 212. When the tape on the first feed tray 11 is almost empty, the feeding assembly 1 can move forward, causing the second feed tray 12 to move to the position corresponding to the first guide groove 211. At the same time, the first feed tray 11 moves to the position corresponding to the third guide groove 213 and connects with the tail end of the tape on the first feed tray 11 in the first guide groove 211. When the tape on the second feed tray 12 is almost empty, the feeding assembly 1 can move backward, causing the second feed tray 12 to move to the position corresponding to the third guide groove 213. At the same time, the tape on the first feed tray 11 is full and moves to the position corresponding to the first guide groove 211. Similarly, at this time, the beginning end of the tape on the first feed tray 11 connects with the tail end of the tape on the second feed tray 12, thereby realizing the continuous connection of the tape. This structure is simple, and the back-and-forth switching method can minimize the occupied area of ​​the device.

[0028] Furthermore, the pressing assembly 3 includes a first cylinder 31 and a second cylinder 32 disposed on the feeding assembly 1, and a pressure plate 33 connected to the second cylinder 32. The first cylinder 31 is used to drive the pressure plate 33 to move along a second direction, and the second cylinder 32 is used to drive the pressure plate 33 to move in the height direction. This achieves precise control of the pressure plate 33 in two dimensions, enabling the tape to be pressed horizontally and vertically as needed, ensuring that the tape remains stable during cutting and splicing, and preventing the tape from moving or deforming during operation.

[0029] Furthermore, the projected area of ​​the pressure plate 33 on the support plate 21 at least covers the first guide groove 211 and the second guide groove 212 or at least covers the first guide groove 211 and the third guide groove 213; and the cutting assembly 4 includes a third cylinder and at least three cutting blades 41 connected to the third cylinder, the at least three cutting blades 41 are arranged along a first direction, and the at least three cutting blades 41 are respectively corresponding to the first guide groove 211, the second guide groove 212, and the third guide groove 213.

[0030] Understandably, by setting the pressure plate 33 to have a projected area on the tray 21 that at least covers the first guide groove 211 and the second guide groove 212, or the first guide groove 211 and the third guide groove 213, the pressure plate 33 can simultaneously press the tape in at least two guide grooves, including the first guide groove 211, thus expanding the pressing range. Combined with at least three cutting blades 41, this allows for simultaneous cutting of the tape in at least two guide grooves. This not only ensures that each piece of tape can be effectively cut with consistent results, but also aligns the tape's head and tail ends, preventing issues such as increased thickness or misalignment at the joint due to uneven cutting. Furthermore, this cutting method reduces the movement path of the cutting component 4 in the first direction, further reducing the overall footprint of the device.

[0031] It is worth noting that in this embodiment, a strip-shaped clearance groove 331 is provided at the bottom center of the pressure plate 33 along the first direction. When it is necessary to cut the tape, the pressure plate 33 presses the tape firmly onto the support plate 21, and then the three cutting blades 41 extend at least partially into the strip-shaped clearance groove 331 and move along the strip-shaped clearance groove 331 to achieve tape cutting. The advantage of this arrangement is that the cutting blades 41 will not interfere with the pressure plate 33 during cutting, and the cutting blades 41 can move along the strip-shaped clearance groove 331, ensuring that the cutting blades 41 can accurately cut the tape and avoid cutting deviation.

[0032] Furthermore, the connecting component 5 includes an adsorption disk 51 and a driving component connected to the adsorption disk 51. The adsorption disk 51 is used to adsorb the connector, and the driving component is used to drive the adsorption disk 51 to move so as to connect the connector to the head and tail ends of the tape. This realizes automated connection of the head and tail ends of the tape, reduces manual operation, and improves the efficiency and quality of connection.

[0033] As described above, in this embodiment, the feeding assembly 1 further includes a mounting frame 13, a fourth cylinder 14 and a fifth cylinder 15 connected to the mounting frame 13, and at least two feeding trays are mounted on the mounting frame 13. The fourth cylinder 14 is used to drive the feeding tray to move along a first direction, and the fifth cylinder 15 is used to drive the feeding tray to move along a second direction, so that the feeding tray can move flexibly in both directions, providing more flexibility for switching of the feeding tray and feeding of the tape.

[0034] Furthermore, the power-driven material pulling assembly 6 includes a power wheel 61 and a limiting wheel 62 disposed below the power wheel 61. The tape is adapted to pass between the power wheel 61 and the limiting wheel 62. The limiting wheel 62 can move up and down under the action of external force to tighten or loosen the tape. The power wheel 61 is configured to rotate to transport the tape when the limiting wheel 62 and the power wheel 61 tighten the tape.

[0035] Understandably, the power-driven material feeding assembly 6 includes a power wheel 61 and a limiting wheel 62. The conveyor belt passes between the power wheel 61 and the limiting wheel 62. The limiting wheel 62 can move up and down under external force to tighten or loosen the conveyor belt. The power wheel 61 rotates to transport the conveyor belt when the limiting wheel 62 tightens the conveyor belt, thereby ensuring that the conveyor belt remains stable during the conveying process and preventing the conveyor belt from slipping or deviating during the conveying process, thus improving the stability of the conveyor belt. Furthermore, through the cooperation of the power wheel 61 and the limiting wheel 62, the conveying speed and tension of the conveyor belt can be precisely controlled, improving the conveying accuracy and providing a more stable supply of conveyor belt for subsequent processing operations.

[0036] Furthermore, the material storage assembly 7 includes a first transition wheel 71 higher than the power pulling assembly 6, a guide rail 72 arranged along the height direction, a guide block 73 adapted to the guide rail 72, a second transition wheel 74 connected to the guide block 73, and a first detection element 75 and a second detection element 76 located on one side of the guide rail 72 and arranged along the height direction. The tape is sequentially wound around the first transition wheel 71 and the second transition wheel 74 to drive the second transition wheel 74 to move along the guide rail 72.

[0037] Understandably, this setup enables the tape to buffer and store material. When the tape feeding speed does not match the subsequent processing speed, the storage component 7 can temporarily store excess tape to prevent tape feeding interruption or accumulation. Meanwhile, the first detection element 75 and the second detection element 76 can monitor the position and status of the tape in the storage component 7 in real time, providing real-time feedback to the production process. This facilitates timely adjustment of the feeding speed and processing parameters, further improving the automation and reliability of production.

[0038] In summary, the specific working process of the tape splicing device shown in this utility model is as follows: when the tape of the first feeding tray 11 is fed in the first guide groove 211, the second feeding tray 12 corresponds to the second guide groove 212. When the tape in the first feed tray 11 is almost empty, the pressure plate 33 of the clamping assembly 3 simultaneously clamps the tape in the first feed tray 11 and the second feed tray 12 located on the tray assembly 2. Simultaneously, the two cutting blades 41 near the first guide groove 211 and the second guide groove 212 simultaneously cut the tape in the first feed tray 11 and the second feed tray 12. Then, the feeding assembly 1 moves forward, causing the second feed tray 12 to move to a position corresponding to the first guide groove 211, while the first feed tray 11 moves to a position corresponding to the third guide groove 213, so that the tail end of the tape in the first feed tray 11 aligns with the head end of the tape in the second feed tray 12. The connecting assembly 5 moves to attach the connector to the tail end of the tape in the first feed tray 11 and the head end of the tape in the second feed tray 12. When the tape in the second feed tray 12 is almost empty, the tape in the first feed tray 11 is full. At this time, the first feed tray 11 is located at a position corresponding to the third guide groove 213. The clamping assembly... The pressure plate 33 of component 3 simultaneously presses the tape of the first feed tray 11 and the second feed tray 12 located in the third guide groove 213 and the first guide groove 211, respectively. The two cutting blades 41 near the first guide groove 211 and the third guide groove 213 simultaneously cut the tape of the first feed tray 11 and the second feed tray 12. Then the feeding assembly 1 moves forward, so that the first feed tray 11 moves to the position corresponding to the first guide groove 211, and the second feed tray 12 moves to the position corresponding to the second guide groove 212, so that the tape head end of the first feed tray 11 is aligned with the tape tail end of the second feed tray 12. The connecting assembly 5 moves to attach the connecting piece to the tape head end of the first feed tray 11 and the tape tail end of the second feed tray 12. Furthermore, since the discharging assembly stores a sufficient length of tape, it is sufficient to continue feeding during the connection time of the first feed tray 11 and the second feed tray 12, thereby realizing continuous feeding and adhesive application without stopping the machine.

[0039] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
