[0002] The display panel is a basic component of the display. During the processing of the display panel, the display panel is generally cleaned by a display panel cleaning device. In the display panel cleaning device, the front and back of the liquid medicine section are the dry section and the water washing section respectively. In order to prevent the liquid medicine and the vapor from entering the adjacent dry section and the water washing section chamber and affecting the adjacent processes, a baffle mechanism is usually set at the inlet and outlet of the liquid medicine section to block the inlet and outlet of the liquid medicine section.

[0003] In the existing display panel cleaning equipment, a linear cylinder is usually set at the inlet and outlet of the liquid medicine section respectively. The linear cylinder drives the connecting rod mechanism to drive the baffle mechanism to lift and lower. After the baffle mechanism is used for a long time, the relative position between the sealing surface of the baffle mechanism and the inlet and outlet of the liquid medicine section will deviate, resulting in a gap between the two, which makes the sealing effect of the baffle mechanism worse, causing the liquid medicine vapor to enter the adjacent connected dry section and water washing section chambers, which has an adverse effect on the cleaning effect of the display panel.

[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] This embodiment provides a display panel cleaning device, which can be applied to the technical field of display panel cleaning to clean the display panel.

[0041] The display panel cleaning device comprises a display panel cleaning device body, in which a dry section, a liquid medicine section, a water washing section connected in sequence and a baffle mechanism arranged at the entrance and the exit of the liquid medicine section are arranged. The baffle mechanism blocks the liquid medicine vapor in the liquid medicine section to prevent the liquid medicine vapor in the liquid medicine section from leaking from the entrance of the liquid medicine section to the dry section and from the exit of the liquid medicine section to the water washing section, thereby causing adverse effects on the display panel.

[0042] like Figure 1 and Figure 2 As shown, the baffle mechanism includes a driving assembly 1, a baffle assembly 2 and a sealing member 3. The driving assembly 1 includes a conveying roller 13 for conveying a display panel, the baffle assembly 2 includes a sealing plate 22, the driving assembly 1 is connected to the sealing plate 22 and the driving assembly 1 can drive the sealing plate 22 to rotate so that the baffle assembly 2 switches between an open position and a closed position; the sealing member 3 is annular and is arranged along the circumference of the sealing plate 22, in the open position, the sealing plate 22 can open the inlet and outlet to be sealed so that the conveying roller 13 can convey the display panel; in the closed position, the sealing member 3 abuts against the inlet and outlet to be sealed.

[0043] Specifically, in this embodiment, the inlet and outlet to be sealed include the liquid inlet and liquid outlet of the display panel cleaning device. Of course, in other embodiments, the baffle mechanism can also open and close the inlet and outlet of other devices.

[0044] In this embodiment, the baffle assembly 2 is usually in a closed position. When the display panel needs to be transported, the driving assembly 1 drives the sealing plate 22 to rotate to an open position.

[0045] Specifically, in the present embodiment, when it is necessary to close the entrance of the medicine liquid segment, the driving component 1 drives the sealing plate 22 at the entrance of the medicine liquid segment to rotate to a closed position. At this time, the sealing member 3 arranged circumferentially along the sealing surface of the sealing plate 22 can abut against the outer wall surface at the entrance of the medicine liquid segment, thereby avoiding the presence of a gap between the sealing plate 22 and the entrance of the medicine liquid segment, which may cause the medicine in the medicine liquid segment to leak from the gap to the dry segment, thereby causing adverse effects on the display panel.

[0046] When it is necessary to close the outlet of the medicine liquid section, the driving component 1 drives the sealing plate 22 at the outlet of the medicine liquid section to rotate to the closed position. At this time, the sealing member 3 arranged circumferentially along the sealing surface of the sealing plate 22 can abut against the outer wall surface at the outlet of the medicine liquid section, thereby avoiding the presence of a gap between the sealing plate 22 and the outlet of the medicine liquid section, which may cause the medicine in the medicine liquid section to leak from the gap to the water washing section, thereby causing adverse effects on the display panel.

[0047] Of course, in other embodiments, the seal 3 arranged along the sealing surface of the baffle assembly 2 may also abut against the inner wall of the entrance and exit of the liquid medicine section; as long as there is no gap between the baffle assembly 2 and the entrance and exit of the liquid medicine section, no excessive restrictions are made here.

[0048] Furthermore, in order to ensure the stability of the installation position of the seal 3 and to better ensure the sealing effect when the baffle assembly 2 is in the closed position, a sealing groove is provided on the baffle assembly 2 to cooperate with the seal 3, and the seal 3 is bonded and set in the sealing groove. By setting the sealing groove to position the seal 3, the accuracy and stability of the connection between the seal 3 and the baffle assembly 2 can be improved, thereby improving the sealing effect when the seal 3 abuts against the outer wall at the inlet of the medicine liquid section or the outer wall at the outlet of the medicine liquid section when the baffle assembly 2 is in the closed position, thereby preventing the leakage of medicine liquid and medicine vapor from causing adverse effects on the display panel.

[0049] Furthermore, in the open position, the sealing surface of the sealing plate 22 is set away from the entrance and exit to be sealed, and the upper edge of the sealing plate 22 is lower than the highest point of the conveying roller 13; illustratively, in the open position, the display panel in the dry section moves to the medicine liquid section via the conveying roller 13 at the entrance of the medicine liquid section. At this time, the sealing surface of the sealing plate 22 is set away from the entrance and exit to be sealed, and the upper edge of the sealing plate 22 is lower than the highest point of the conveying roller 13, and the sealing plate 22 will not interfere with the transportation of the display panel.

[0050] Furthermore, if Figure 1 As shown, the driving assembly 1 includes a driving member 11 and a connecting shaft 12, one end of the connecting shaft 12 is connected to the output end of the driving member 11, and the sealing plate 22 is connected to the connecting shaft 12. The driving member 11 can drive the connecting shaft 12 to rotate to drive the sealing plate 22 to rotate, and the conveying roller 12 is rotatably arranged on the connecting shaft 12. The sealing plate 22 is driven to rotate by the driving member 11, so that the sealing plate 22 is switched between the open position and the closed position.

[0051] Furthermore, if Figure 2 As shown, the driving member 11 can drive the connecting shaft 12 to rotate 180° so that the sealing plate 22 switches between the open position and the closed position. The baffle assembly 2 also includes a connecting plate 21, which is connected to the connecting shaft 12, and the sealing plate 22 is fixedly connected to the connecting plate 21. In the open position, the distance between the upper edge of the sealing plate 22 and the connecting plate 21 is smaller than the distance between the lower edge of the sealing plate 22 and the connecting plate 21. The connecting plate 21 is connected to the connecting shaft 12, so that when the driving assembly 1 drives the connecting shaft 12 to rotate, it can drive the connecting plate 21 to rotate, and then the sealing plate 22 fixed on one side of the connecting plate 21 can also rotate with the connecting shaft 12 to abut or separate from the outer wall surface of the inlet and outlet of the liquid medicine section. Specifically, as Figure 2As shown, in the open position, the distance between the upper edge of the sealing plate 22 and the connecting plate 21 is a, and the distance between the lower edge of the sealing plate 22 and the connecting plate 21 is b, where a is smaller than b. This arrangement ensures that when the baffle assembly 2 is in the open position, the upper edge of the sealing plate 22 is lower than the highest point of the conveying roller 13, so that when the display panel needs to pass through the entrance and exit, it can pass smoothly without being hindered by the sealing plate 22.

[0052] It can be understood that when the connecting shaft 12 rotates 180° and the baffle assembly 2 switches to the closed position, the distance between the upper edge of the sealing plate 22 and the connecting plate 21 is b, and the distance between the lower edge of the sealing plate 22 and the connecting plate 21 is a. At this time, the sealing surface of the sealing plate 22 can block the entrance and exit to be sealed.

[0053] In this embodiment, if Figure 3 and Figure 4 As shown, when the baffle assembly 2 is in the closed position, the connecting plate 21 is arranged horizontally, the sealing plate 22 is arranged vertically, and the sealing plate 22 is arranged vertically on one side of the connecting plate 21 so that the sealing member 3 abuts against the outer wall surface at the entrance and exit of the liquid medicine section. When the baffle assembly 2 needs to be switched to the open position, the driving member 11 drives the connecting shaft 12 to rotate 180°, so that the baffle assembly 2 is switched to the open position, thereby opening the entrance and exit of the liquid medicine section for transporting the display panel.

[0054] Exemplarily, taking the entrance position of the medicine liquid section as an example, when the entrance is in a closed state, the baffle assembly 2 is in a closed position, blocking the entrance of the medicine liquid section; when the entrance of the medicine liquid section needs to be opened, the baffle assembly 2 is controlled to rotate 180°, and the baffle assembly 2 is rotated to the open position, so that the entrance of the medicine liquid section is in an open state.

[0055] Further, see Figure 5 In order to ensure that the connecting shaft 12 can stably drive the baffle assembly 2 to rotate along with the driving assembly 1, the connecting plate 21 is further provided with an arc-shaped fixing member 23, and the two ends of the arc-shaped fixing member 23 are connected to the connecting plate 21 to enclose a connecting shaft mounting hole, and the connecting shaft 12 is installed in the connecting shaft mounting hole. Specifically, the two ends of the arc-shaped fixing member 23 are provided with thread grooves, and the connecting plate 21 is provided with fixing holes at positions corresponding to the two ends of the arc-shaped fixing member 23. Bolts pass through the fixing holes and are threadedly connected with the thread grooves on the arc-shaped fixing member 23 so that the arc-shaped fixing member 23 is connected to the connecting plate 21 and encloses a connecting shaft mounting hole.

[0056] Correspondingly, in this embodiment, the cross-section of the connecting shaft 12 is semicircular to match the shape of the connecting shaft mounting hole; the side of the connecting shaft 12 includes a planar portion, which is arranged in close contact with the connecting plate 21, so that no relative rotation occurs between the connecting shaft 12 and the connecting plate 21.

[0057] Further, see Figure 5 In order to improve the stability of the abutment between the connecting plate 21 and the connecting shaft 12, to prevent the connecting shaft 12 and the connecting plate 21 from rotating relative to each other when the driving member 11 drives the connecting shaft 12 to rotate, and to prevent the connecting shaft 12 from moving along its own axial direction, the arc-shaped fixing member 23 is provided with an abutment member 231 capable of abutting against the connecting shaft 12. Specifically, the abutment member 231 is a screw, which passes through the arc-shaped fixing member 23 and abuts against the connecting shaft 12. Of course, in other embodiments, the screw can also pass through the arc-shaped fixing member 23 and be connected to the connecting shaft 12.

[0058] Furthermore, if Figure 3-5 As shown, a plurality of arc-shaped fixing member groups are arranged on the connecting plate 21 , each arc-shaped fixing member group includes two arc-shaped fixing members 23 arranged relatively and spaced apart, and a conveying roller 13 is arranged between the two arc-shaped fixing members 23 of each arc-shaped fixing member group.

[0059] Furthermore, the connecting plate 21 is provided with avoidance grooves 24 corresponding to the conveying rollers 13. By placing the conveying rollers 13 in the avoidance grooves 24, on the one hand, the conveying rollers 13 can be prevented from axially moving along the connecting shaft 12, ensuring that no accidents occur when transporting the display panel, and on the other hand, the conveying rollers 13 can be ensured to rotate smoothly; at the same time, the arc-shaped fixing members 23 on both sides of the conveying rollers 13 are respectively connected to the connecting plates 21 on both sides of the avoidance grooves 24, which can better ensure that the connecting shaft 12 and the connecting plate 21 do not rotate relative to each other.

[0060] In other embodiments, the connecting shaft 12 and the connecting plate 21 may also be connected together by welding. In this way, there is no need to provide the arc-shaped fixing member 23, thus saving costs.

[0061] like Figure 2 As shown, in this embodiment, the driving member 11 is a rotary cylinder. The rotary cylinder also includes a cylinder body, a cylinder fixing plate and a cylinder coupling 4. The cylinder body is mounted on the cylinder fixing plate, and the cylinder body is fixed by bolting the cylinder fixing plate to the bracket on the liquid medicine section. One end of the cylinder coupling 4 is connected to the output end of the cylinder body, and the other end is connected to the connecting shaft 12 to drive the connecting shaft 12 to rotate, thereby ensuring the stability of the connecting shaft 12 during operation and avoiding a gap between the sealing member 3 and the inlet and outlet of the liquid medicine section.

[0062] Furthermore, an intermediate shaft is provided at the output end of the cylinder coupling 4, and a coupling 5 is further provided between the intermediate shaft and the connecting shaft 12 to further ensure the stability of the connecting shaft 12 during operation.

[0063] In order to ensure the sealing effect of the seal 3 when the sealing plate 22 rotates to abut against the outer wall at the outlet and inlet of the liquid medicine section, the seal 3 is made of rubber or silicone, which is soft and flexible and can improve the sealing performance.

[0064] Furthermore, in this embodiment, a sensor is also provided on the baffle mechanism. The sensor also includes a sensor bracket, a bracket fixing member and a sensor body. The sensor bracket is sleeved on the connecting shaft 12, one end of the bracket fixing member is connected to the sensor bracket, and the other end of the bracket fixing member is connected to the outer wall of the liquid medicine section, and the sensor body is provided on the sensor bracket. Specifically, the sensor bracket is sleeved on the connecting shaft 12 through a bearing. Of course, in other embodiments, the sensor bracket can also be directly sleeved on the connecting shaft 12, and it is only necessary to ensure that the sensor bracket does not rotate with the connecting shaft 12 when the connecting shaft 12 rotates, and no excessive restrictions are made here.

[0065] When the sensor body detects that the display panel needs to pass through the liquid medicine section, the signal is transmitted to the rotating cylinder at the entrance of the liquid medicine section, and the rotating cylinder there drives the connecting shaft 12 to rotate and drive the baffle assembly 2 to flip and reset to open the entrance and exit of the liquid medicine section. When the sensor body detects that the display panel has passed through the entrance of the liquid medicine section, the rotating cylinder at the entrance of the liquid medicine section drives the connecting shaft 12 to rotate and drive the baffle assembly 2 to flip and reset, and separate the liquid medicine section from the adjacent dry section to prevent leakage of liquid medicine vapor. When the sensor body detects that the display panel has passed through the exit of the liquid medicine section, the sensor body transmits a signal to the rotating cylinder at the exit of the liquid medicine section, and the rotating cylinder there drives the connecting shaft 12 to rotate and drive the baffle assembly 2 to flip and reset, and separate the liquid medicine section from the adjacent water washing section chamber to prevent leakage of liquid medicine vapor.

[0066] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
