[0001] This utility model belongs to the technical field of tank cleaning equipment for solar cell production, and particularly relates to a door of a tank cleaning equipment and its door panel delayed opening mechanism. Background Technology
[0002] In the manufacturing process of solar cells, silicon wafers need to undergo processes such as cleaning, diffusion, annealing, coating, and screen printing. In commonly used tank-type cleaning equipment, solar cells are placed in baskets and transported by robotic arms. They then undergo chemical reactions in tanks containing different solutions and are dried, ultimately completing the cleaning process.
[0003] The robotic arm moves very quickly, and if a person pushes open the door and immediately enters the operating area at this time, it may cause injury.
[0004] Therefore, how to prevent personnel from entering the operating area immediately upon opening the door to avoid safety hazards is a technical problem that urgently needs to be solved by those skilled in the art.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0049] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0050] See Figure 1 This disclosure provides a trough-type cleaning equipment door, including: a linkage assembly 100, which has at least two linkages 110 connected in series, wherein adjacent linkages 110 are rotatably connected by a linkage shaft 200 and pins 120 are provided at both ends of the linkage assembly 100. A door panel 400 and a door frame 500 are provided, with a pin sleeve 300 respectively provided at the edge of the door panel 400 and the door frame 500; wherein the linkage assembly 100 is inserted into the pin sleeve 300 through the pins 120 to limit the opening of the door panel 400 and the door frame 500, so that the door panel 400 can only be opened a certain distance. After the staff observes through the door gap and confirms safety, they remove the linkage assembly 100 to achieve delayed entry into the equipment, thus preventing safety accidents.
[0051] like Figure 2 As shown, when the door panel is in the closed state, the linkage assembly 100 is in a relatively bent state, and the included angle formed by the two linkages 110 is an acute angle.
[0052] See Figure 3 When the door panel is opened, the linkage assembly 100 is stretched to limit the opening of the door panel 400 and the door frame 500, so that the door panel 400 can only open a certain distance of door gap. After the staff observes through the door gap and confirms that it is safe, they remove the linkage assembly 100 to achieve delayed entry into the equipment in order to prevent safety accidents from occurring.
[0053] See also Figure 1 In some embodiments, the upper edges of the two pin sleeves 300 are at the same horizontal height, and the depth of one pin sleeve 300 is greater than the depth of the other pin sleeve 300, so as to match the long and short pins 120 respectively. By using pins 120 and pin sleeves 300 of different lengths, the position or angle of the connecting rod 110 can be adjusted within a certain range, which provides greater flexibility during assembly.
[0054] See also Figure 1 In some embodiments, the sleeve 300 can be a through-hole structure, and the pin 120 is adapted to be inserted into one end of the sleeve 300 and exit through the other end. With the through-hole sleeve 300, the pin 120 can be quickly positioned and inserted into the sleeve 300, facilitating the disassembly and installation of the connecting rod assembly 100.
[0055] See also Figure 1 In some embodiments, the connecting rod shaft 200 is provided with a washer 210, which is elastic and has its upper and lower end faces abutting against two adjacent connecting rods 110 respectively. Specifically, the elastic washer 210 can absorb vibration and impact, playing a role in buffering and shock absorption, thereby reducing the wear of the connecting rod assembly 100.
[0056] See Figure 4 and Figure 5 Some embodiments also provide a trough-type cleaning equipment door, including: a linkage assembly 100, which includes at least one linkage 110, wherein pins 120 are provided at both ends of the linkage assembly 100. A door panel 400 and a door frame 500 are provided at the edges of the door panel 400 and the door frame 500, respectively; wherein the pin sleeve 300 on the door panel 400 side includes a sliding groove 310 to accommodate a pin 120 and slide back and forth when the door panel 400 is opened and closed, and another pin 120 is disposed in the pin sleeve 300 on the door frame 500 side and rotates when the door panel 400 is opened and closed, so that when the door is opened, the linkage assembly 100 limits the opening degree between the door panel 400 and the door frame 500.
[0057] like Figure 4 As shown, when the door panel is in the closed state, the linkage assembly 100 is parallel to the door panel 400.
[0058] See Figure 5 When the door panel is opened, the latch 120 located on the side of the door panel 400 is adapted to slide in the sliding groove 310, and the other latch 120 rotates in the pin sleeve 300 on the side of the door frame 500 to limit the opening of the door panel 400 and the door frame 500, so that the door panel 400 can only open a certain distance of door gap. After the staff observes through the door gap and confirms that it is safe, they remove the connecting rod assembly 100 to achieve delayed entry into the equipment in order to prevent safety accidents from occurring.
[0059] See Figure 1 In some embodiments, a door panel delayed opening mechanism is also provided, which is assembled between the door panel 400 and the door frame 500, including: a linkage assembly 100, which is provided with at least two linkages 110 connected in series, wherein adjacent linkages 110 are rotatably connected by a linkage shaft 200 and pins 120 are provided at both ends of the linkage assembly 100; a pin sleeve 300 is provided at the edges of the door panel 400 and the door frame 500 respectively; wherein the linkage assembly 100 is inserted into the pin sleeve 300 through the pins 120 to limit the opening degree of the door panel 400 and the door frame 500.
[0060] See Figure 4 and Figure 5 In some embodiments, the pin sleeve 300 located on the door panel 400 side includes a sliding groove 310 to accommodate a pin 120 and slide back and forth when the door panel 400 is opened and closed, and another pin 120 is disposed in the pin sleeve 300 on the door frame 500 side and rotates when the door panel 400 is opened and closed, so that when the door is opened, the linkage assembly 100 limits the opening degree between the door panel 400 and the door frame 500.
[0061] In summary, the door of this trough-type cleaning equipment is designed with pin sleeves 300 on the door frame 500 and door panel 400, and the pins 120 on the connecting rod assembly 100 are adapted to be inserted into the corresponding pin sleeves 300 to limit the opening of the door panel 400 and the door frame 500. When the door is opened, due to the limiting effect of the connecting rod assembly 100, the door panel 400 can only be opened a certain distance. After the staff observes through the door gap and confirms that it is safe, they can remove the connecting rod assembly 100 to achieve a delayed entry into the equipment, thereby preventing safety accidents.
[0062] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0063] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and 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 of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0064] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0065] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0066] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
