[0030] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Please see Figure 1 and Figure 2 The desktop transfer printing device for laboratory use provided by this utility model will now be described. The desktop transfer printing device for laboratory use includes a mobile carrier and a transfer system; the mobile carrier includes an unwinding carriage 6 and a rewinding carriage 7, both of which are equipped with rollers 9 at their bottoms, and both the unwinding carriage 6 and the rewinding carriage 7 include a table surface; the transfer system includes an unwinding device 1, a roller transfer device 2, and a rewinding device, the unwinding device 1 and the roller transfer device 2 being arranged sequentially from left to right on the table surface of the unwinding carriage 6, and the rewinding device being arranged on the table surface of the rewinding carriage 7.

[0032] This solution miniaturizes the existing transfer printing production line, placing the machines on the unwinding trolley 6 and the rewinding trolley 7 respectively. Separating the unwinding and rewinding trolleys reduces both the length of the trolleys and the turning radius during movement, and also controls the overall weight of the trolleys, reducing the pushing force required for personnel to move them.

[0033] When using this desktop transfer device in a laboratory setting, first move the unwinding carriage 6 and the rewinding carriage 7 to the appropriate working position and adjust their relative spacing using the rollers 9 at the bottom to ensure smooth material transfer during the transfer process.

[0034] After the work begins, the unwinding device 1 releases the substrate to be transferred onto the unwinding trolley 6. Under its own tension and the traction of the subsequent devices, the substrate is conveyed to the right to the roller transfer device 2 located on the same unwinding trolley 6. The roller transfer device 2 performs the transfer process on the substrate. After completing the preset transfer operation, the substrate continues to be conveyed to the right and is finally collected by the winding device located on the winding trolley 7.

[0035] The desktop transfer device for laboratories provided by this utility model has the following advantages compared with the prior art:

[0036] (1) This equipment integrates the unwinding device 1 and the roller transfer device 2 on the table of the unwinding carriage 6, and the rewinding device is set on the table of the rewinding carriage 7. Compared with the existing integrated transfer equipment, the split design greatly reduces the volume and floor space of individual components. Moreover, both the unwinding carriage 6 and the rewinding carriage 7 are equipped with rollers 9 at the bottom, which can be easily pushed and moved, effectively solving the problems of large floor space and difficult movement of existing transfer equipment, and is more suitable for the limited space environment of the laboratory. It realizes the overall lightweight and easy movement of the transfer machine.

[0037] (2) The split carriage structure makes the unwinding, roller transfer and rewinding stages relatively independent. During the experiment, the unwinding carriage 6 or the rewinding carriage 7 can be moved separately as needed to adjust the distance between them, which facilitates flexible adjustment of the transfer parameters and improves the convenience of experimental operation. In addition, the cooperation between the unwinding carriage 6 and the rewinding carriage 7 reduces the distance between the devices, thereby reducing the belt length of the transfer machine and reducing the waste of experimental materials.

[0038] (3) Due to the compact overall layout of the equipment, the distance between the unwinding device 1, the roller transfer device 2 and the winding device can be flexibly adjusted according to the experimental requirements, which can shorten the substrate's travel path, thereby reducing the waste of experimental materials caused by the long travel path, reducing experimental costs, and better meeting the laboratory's small-batch, multi-batch experimental requirements.

[0039] Optionally, rollers 9 are made of ferrules, and ferrules are installed at the four corners of the bottom of both the unwinding carriage 6 and the rewinding carriage 7. After the unwinding carriage 6 and the rewinding carriage 7 are pushed to the designated position, the feet of the ferrules can be lowered and the level of the table surface of the unwinding carriage 6 and the rewinding carriage 7 can be adjusted.

[0040] In some possible embodiments, please refer to Figure 2Both the unwinding trolley 6 and the rewinding trolley 7 include a base and a support frame; the rollers 9 are installed at the lower end of the base; the support frame is located at the upper end of the base, and the table is located at the upper end of the support frame, forming an electrical cabinet installation space between the table and the base.

[0041] The space between the countertop and the base provides a dedicated area for the electrical control components required by the equipment. This avoids the messy wiring caused by haphazard placement of electrical equipment, while also providing some physical protection for the electrical components, reducing the impact of external collisions and dust, and ensuring the stable operation of the equipment's electrical system.

[0042] Within the limited space of a laboratory, by embedding electrical components into the gap between the countertop and the base, the overall layout of the equipment can be made more compact without taking up additional floor or table space in the laboratory.

[0043] Electrical components are centrally installed in the electrical cabinet installation space. When operators need to inspect, repair or replace components in the electrical parts, they can operate directly in the dedicated electrical cabinet installation space corresponding to each part, which improves the maintenance efficiency of the equipment.

[0044] Correspondingly, the transfer system includes an unwinding cabinet 8, a rewinding cabinet 10, and a hydraulic station 11; the unwinding cabinet 8 is correspondingly set to the unwinding device 1, and is located within the cabinet installation space of the unwinding trolley 6; the rewinding cabinet 10 is correspondingly set to the rewinding device, and is located within the cabinet installation space of the rewinding trolley 7; the hydraulic station 11 is located within the cabinet installation space of the rewinding trolley 7 and is situated on one side of the rewinding cabinet 10; the hydraulic outlet of the hydraulic station 11 is connected to the hydraulic cylinder 16 on the roller transfer device 2.

[0045] The unwinding control cabinet 8 is correspondingly set with the unwinding device 1, and the rewinding control cabinet 10 is correspondingly set with the rewinding device, forming a one-to-one precise control relationship between the electrical control and functional devices. This reduces interference and delay in signal transmission and improves the response speed and control accuracy of the unwinding and rewinding actions. The hydraulic station 11 is located in the cabinet installation space of the rewinding trolley 7 and is connected to the hydraulic cylinder 16 of the roller transfer device 2, ensuring stable pressure and precise adjustment during the roller transfer process, further guaranteeing the transfer quality.

[0046] The unwinding control cabinet 8 and the rewinding control cabinet 10 control the corresponding unwinding and rewinding devices nearby, which shortens the laying distance of electrical lines and reduces line loss and fault risk.

[0047] Optionally, through-wall plates 17 are provided on both the unwinding trolley 6 and the winding trolley 7. The winding and unwinding electrical cabinet is embedded in the electrical cabinet installation space of the winding and unwinding trolley 6, and the wiring of each device on the two tables is connected to the inside of the electrical cabinet through the through-wall plates 17 on the tables.

[0048] In some possible embodiments, please refer to Figure 2 The hydraulic station 11 is connected to the hydraulic cylinder 16 via hydraulic pipelines. The hydraulic pipelines include a hydraulic rigid pipe 12, a through-wall hydraulic pipe joint 13, and a hydraulic hose 14. The hydraulic rigid pipe 12 is connected to the output end of the hydraulic station 11. The through-wall hydraulic pipe joint 13 passes through the table of the winding trolley 7, and the lower end of the through-wall hydraulic pipe joint 13 is connected to the hydraulic rigid pipe 12. The hydraulic hose 14 connects the upper end of the through-wall hydraulic pipe joint 13 to the hydraulic cylinder 16.

[0049] The hydraulic pipeline is composed of a rigid hydraulic pipe 12, a through-wall hydraulic pipe joint 13, and a hydraulic hose 14. The rigid hydraulic pipe 12 connects to the output end of the hydraulic station 11 and can be stably laid out within the electrical cabinet installation space of the winding trolley 7, reducing pipeline swaying caused by the confined space. The through-wall hydraulic pipe joint 13 passes through the table surface of the winding trolley 7. The through-wall hydraulic pipe joint 13 forms a reliable transition connection point by passing through the table surface, reducing the risk of leakage at pipeline bends. The hydraulic hose 14 connects the through-wall joint to the hydraulic cylinder 16, which can flexibly adapt to the action requirements of the roller transfer device 2, make up for the defects of rigid pipes being rigid and not easy to bend, and make the pipeline layout more in line with the spatial structure and motion characteristics of the equipment.

[0050] In addition, the through-wall hydraulic pipe joint 13 facilitates the installation and removal of the hydraulic hose 14.

[0051] Optionally, a self-sealing quick connector 15 is provided between the hydraulic hose 14 and the hydraulic cylinder 16. The addition of the self-sealing quick connector 15 between the hydraulic hose 14 and the hydraulic cylinder 16 facilitates the quick connection or disconnection of the hydraulic lines when the two trolleys are docked or separated.

[0052] In some possible embodiments, the unwinding carriage 6 and the winding carriage 7 are detachably connected by means of a connector.

[0053] Laboratory space is usually limited, and the placement of equipment may need to be adjusted according to different experimental projects. The detachable connection between the unwinding carriage 6 and the rewinding carriage 7 allows the two to be stored separately when the equipment is not in use, reducing the space occupied; when other experimental operations are being carried out, one of the carriages can also be easily moved aside to make room for other experimental equipment, thereby improving the utilization efficiency of laboratory space.

[0054] When conducting the transfer experiment, the unwinding carriage 6 and the rewinding carriage 7 are fixedly connected as a whole by the connector, which can reduce the relative displacement between the two during the working process, ensure the stability of the substrate transmission path, and avoid the transfer accuracy being affected by carriage shaking.

[0055] When mobile equipment needs to be moved or the layout adjusted, the detachable connection design allows the two to be separated, and the winding trolley 7 and unwinding trolley 6 can be pushed independently. The reduced length of the two trolleys and the shortened turning radius during movement lower the difficulty of movement; they can flexibly adapt to different space requirements and operating scenarios in the laboratory; and the smaller weight of each trolley reduces the effort required for staff to move them.

[0056] Optionally, the connector can adopt a hook-and-loop structure, a pin structure, etc.

[0057] When the connector is a hook and loop structure, several hooks are installed on the side end face of the unwinding trolley 6 near the winding trolley 7, with the openings of the hooks facing the winding trolley 7; correspondingly, on the side end face of the winding trolley 7 near the unwinding trolley 6, loops are installed that match the number of hooks on the unwinding trolley 6 and are positioned accordingly. The size of the loops is adapted to the openings of the hooks to ensure that the hooks can smoothly hook onto the loops.

[0058] The hook can be fixed to the support frame, base, or table of the unwinding trolley 6 by bolts.

[0059] Correspondingly, when a hanging ring is installed on the end face of the unwinding trolley 6, a hook is installed on the corresponding end face of the winding trolley 7.

[0060] The corresponding installation method of hooks and rings enables quick alignment and connection. Operators only need to push the two vehicles closer together so that the hooks naturally hook onto the rings to complete the fixation.

[0061] Multiple connectors can be arranged longitudinally. When multiple sets of hook ring structures connect the winding trolley 7 and the unwinding trolley 6, multiple connectors can further improve the connection stability between the two.

[0062] When the connector is a pin structure, several pin seats are arranged at horizontal or vertical intervals on the end face of the unwinding trolley 6 near the winding trolley 7. A pin is movably inserted into each pin seat, allowing it to reciprocate horizontally or vertically. Correspondingly, slots matching the number and position of the pin seats are provided on the end face of the winding trolley 7 near the unwinding trolley 6. The size of the slots is adapted to the diameter of the pins to ensure smooth insertion of the pins. The pin seats can be fixed to the trolley's support frame or base by welding or bolting.

[0063] By inserting the pin into the slot in a straight line, the two carriages can be quickly and accurately connected, avoiding misalignment or loosening after connection. After the pin is inserted into the slot, it can be self-locked by its own weight or the added spring-loaded locking structure, preventing the pin from accidentally coming out due to vibration or other factors during equipment operation, ensuring the reliability of the connection between the two carriages, and further improving the stability of the transfer process.

[0064] In some possible embodiments, please refer to Figure 2 Handles 18 are provided on both the unwinding trolley 6 and the winding trolley 7, which facilitates the movement of the trolleys. When a connector is present, the handle 18 is located on the end face of the trolley away from the connector.

[0065] In some possible embodiments, please refer to Figure 2 The table surface of the unwinding trolley 6 is at the same height as the table surface of the winding trolley 7.

[0066] During the transfer process, the substrate needs to be output from the unwinding device 1 on the unwinding trolley 6, and after passing through the roller transfer device 2, it is transferred to the winding device on the winding trolley 7. The unwinding device 1, the roller transfer device 2, and the winding device are respectively installed on the tables of the two trolleys. The tables are at the same height so that the working centers of each device are on the same horizontal line, which facilitates the adjustment of the height of the structure in each device and keeps the substrate such as the electrode sheet on the same horizontal plane during the transfer process, thereby reducing stress and deformation during the transfer process and improving the efficiency of the transfer work.

[0067] When the table height is consistent, operators can keep their line of sight at the same level when observing the substrate transfer status, checking the transfer effect, or adjusting the equipment, without having to frequently adjust their body posture, thus reducing operator fatigue.

[0068] In some possible embodiments, please refer to Figure 1 The winding device includes a film winding assembly 3 and an electrode winding assembly 5 arranged sequentially. After the electrode transfer is completed, the electrode is wound onto the electrode winding assembly 5, and the film is wound onto the film winding assembly 3.

[0069] The electrode winding assembly 5 is spaced behind the membrane winding assembly 3; a thickness measuring assembly 4 is also provided between the electrode winding assembly 5 and the membrane winding assembly 3, which is used to detect the thickness of the electrode online.

[0070] In this scheme, the electrode sheet is placed on the electrode sheet roll 20 on the unwinding device 1, the A film is placed on the A film roll 19 on the unwinding device 1, and the B film is placed on the B film roll 21 on the unwinding device 1. The electrode sheet, A film, and B film move from front to back into the roller transfer device 2, where they are squeezed by the upper and lower pressure rollers 22 and the transfer is completed. After the transfer is completed, the electrode sheet, A film, and B film continue to move backward, where the A film and B film are respectively wound up by the A film winding roller 23 and the B film winding roller 24 of the film winding assembly 3. After passing through the winding assembly and the thickness measuring assembly 4, the electrode sheet enters the electrode sheet winding assembly 5 and is wound up by the electrode sheet winding roller 25 on the electrode sheet winding assembly 5.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
