[0034] like Figure 1 As shown, the training device 100 for applying glue to an exterior wall may include four panels 110. A glue gap 120 may be formed between the four panels 110. Figure 2 As shown, the four plates 110 can be arranged in two rows and two columns, and the gluing gap 120 can be in a "cross" shape. The "cross" shaped gluing gap 120 can be used to practice gluing operations with intersection areas (for example, "cross" shaped intersection areas). In some embodiments, the four plates can be arranged in a row, and the gluing gap can be in the form of three "1" shaped vertical grooves. In some embodiments, the four plates can be arranged in a column, and the gluing gap can be in the form of three "I" shaped horizontal grooves. Three "1" shaped vertical grooves and / or three "I" shaped horizontal grooves can be used for multiple students to practice gluing operations at the same time, which can improve the efficiency of practical training. This specification does not limit the arrangement of the four plates 110 and the shape of the gluing gap 120. The following is an example of four plates 110 arranged in two rows and two columns and the gluing gap 120 being in a "cross" shape.

[0035] In some embodiments, the materials of the four plates 110 may be the same or different. As an example, the materials of the four plates 110 may include but are not limited to copper, aluminum, iron alloy, stainless steel, phenolic plastic, polyurethane plastic, silicone resin or acrylic resin. In some embodiments, the shapes of the four plates 110 may be the same or different. As an example, the shapes of the four plates 110 may include but are not limited to square, rectangle, right triangle or right trapezoid.

[0036] A boss may be provided on one side of one of the two adjacent plates near the gluing gap. The upper surface of the boss can fit with the lower bottom surface of the other of the two adjacent plates. In some embodiments, the upper surface of the boss can be understood as the side of the boss opposite to the other of the two adjacent plates. In some embodiments, the lower bottom surface of the other of the two adjacent plates can be understood as the side of the plate opposite to the boss. The boss and the side walls of the two adjacent plates near the gluing gap can form a gluing gap. Figure 2As shown, the four plates 110 may include a first plate 111, a second plate 112, a third plate 113 and a fourth plate 114. The glue gap 120 may include a first glue gap 121, a second glue gap 122, a third glue gap 123 and a fourth glue gap 124. The first plate 111 is adjacent to the second plate 112 to form a first glue gap 121. A first boss 1111 may be provided on one side of the first plate 111 close to the first glue gap 121, and the upper surface of the first boss 1111 can be fitted with the lower surface of the second plate 112. The first glue gap 121 may be formed between the first boss 1111 and the first plate 111 and the second plate 112. In some embodiments, a boss may be provided on one side of the second plate 112 close to the first glue gap 121, and the upper surface of the boss can be fitted with the lower surface of the first plate 111. Similarly, the first plate 111 is adjacent to the third plate 113, forming a second gluing gap 122. A second boss 1112 may be provided on one side of the first plate 111 close to the second gluing gap 122, and the upper surface of the second boss 1112 can be fitted with the lower surface of the third plate 113. A second gluing gap 122 may be formed between the second boss 1112 and the first plate 111 and the third plate 113. In some embodiments, a boss may be provided on one side of the third plate 113 close to the second gluing gap 122, and the upper surface of the boss can be fitted with the lower surface of the first plate 111.

[0037] like Figure 3 As shown, the first plate 111 may be provided with a first boss 1111 and a second boss 1112 on both sides close to the glue gap 120. In some embodiments, the first boss 1111 and the second boss 1112 may be an integral structure. In some embodiments, the material of the first boss 1111 and / or the second boss 1112 may be the same as or different from that of the first plate 111. In some embodiments, the thickness of the first boss 1111 and / or the second boss 1112 may be less than that of the first plate 111, may be greater than that of the first plate 111, or may be equal to that of the first plate 111. Figure 3 As shown, the lower surface of the first boss 1111 and / or the second boss 1112 may be flush with the lower bottom surface of the first plate 111. In some embodiments, the length of the first boss 1111 and / or the second boss 1112 may be greater than the length of the first plate 111. The embodiments of this specification do not impose any restrictions on the width and thickness of the first boss 1111 and / or the second boss 1112, as long as the upper surface of the boss can fit with the lower bottom surface of the other plate of the two adjacent plates, and the boss and the side walls of the two adjacent plates near the glue gap can form a glue gap.

[0038] The training device 100 may include a gap adjustment device. The gap adjustment device may be used to drive at least three plates to move to adjust the width of the gluing gap. In some embodiments, the gap adjustment device may include a gap width adjustment device. In some embodiments, the gap width adjustment device may be used to drive three plates to move to adjust the width of the gluing gap. For example, the gap width adjustment device may include three first drive devices, each of which may be used to drive one of the three plates to move. Figure 2 As shown, three first driving devices can be installed on the bottom, side or upper surface of the first plate 111, the second plate 112 and the fourth plate 124 respectively. The third plate 113 may not be installed with any driving device. One first driving device can be used to drive the first plate 111 to move in the direction indicated by arrow a, and arrow a indicates the vertical upward direction. One first driving device can be used to drive the second plate 112 to move in the direction indicated by arrow b, and arrow b indicates a direction of 45° to the horizontal dotted line. One first driving device can be used to drive the fourth plate 114 to move in the direction indicated by arrow c, and arrow c indicates the horizontal right direction.

[0039] In some embodiments, the gap width adjustment device can be used to drive the four plates to move so as to adjust the width of the glue gap. For example, the gap width adjustment device can include four first drive devices, each of which can be used to drive one of the plates to move. In some embodiments, the four first drive devices can be installed on the bottom, side or upper surface of the first plate 111, the second plate 112, the third plate 123 and the fourth plate 124, respectively. In some embodiments, the four first drive devices can drive the four plates to move in any direction on a plane. Figure 2As shown, for example, four first drive devices can respectively drive four plates to move in the horizontal dotted line direction of the plane where the four plates are located to adjust the width of the first glue gap 121 and the third glue gap 123. For another example, four first drive devices can respectively drive four plates to move in the vertical dotted line direction of the plane where the four plates are located to adjust the width of the second glue gap 122 and the fourth glue gap 124. For another example, four first drive devices can respectively drive four plates to move in the direction of the plane where the four plates are located at any angle to the horizontal dotted line to simultaneously adjust the width of the first glue gap 121, the second glue gap 122, the third glue gap 123 and the fourth glue gap 124. As an example, a first drive device can drive the first plate 111 to move in the direction shown by arrow l, and arrow l indicates a 45° direction with the horizontal dotted line. A first drive device can drive the second plate 112 to move in the direction shown by arrow b, and arrow b indicates a 45° direction with the horizontal dotted line. A first driving device can drive the third plate 113 to move in the direction indicated by arrow n, where arrow n indicates a direction at 45° to the horizontal dotted line. A first driving device can drive the fourth plate 114 to move in the direction indicated by arrow m, where arrow m indicates a direction at 45° to the horizontal dotted line. This specification does not impose any restrictions on the specific driving movement direction, as long as the width of the first glue gap 121 and the third glue gap 123 in the "cross" glue gap 120 are equal, and the width of the second glue gap 122 and the fourth glue gap 124 are equal.

[0040] like Figure 4 As shown, a first driving device 130 is installed at the bottom of the first plate 111 as an example for explanation. In some embodiments, the bottom of the first plate 111 can be understood as the lower bottom surface of the first plate 111. The first driving device 130 can include a first driving part 131 and a first power device 132. The first driving part 131 and the first power device 132 can be connected in a transmission manner. The first driving part 131 can be used to move under the drive of the first power device 132, thereby driving the first plate 111 to move to adjust the width of the gluing gap 120. In some embodiments, the first plate 111 can include a guide rail 1114 for limiting the movement direction of the first driving part 131. In some embodiments, the first plate 111 can also include a connecting member 1113. The connecting member 1113 can be used to connect the first driving part 131 and the first plate 111. In a specific embodiment, the first power device 132 can include a first motor, and the first driving part 131 can include at least two first telescopic rods. The width of the gluing gap between two adjacent plates can be adjusted by controlling the elongation length of the at least two first telescopic rods. In some alternative embodiments, the first driving unit 131 may also include but is not limited to a linear transmission mechanism, a hinge transmission mechanism, a gear rack transmission mechanism, a screw nut transmission mechanism, etc.

[0041] In some embodiments, the first driving device 130 may be installed on the side of the first plate 111. In some embodiments, the first plate 111 may not include a connecting piece. The first driving part 131 of the first driving device 130 may be directly connected to the first plate 111.

[0042] Figure 5 It is a schematic diagram showing a plate provided with a retractable boss according to some embodiments of the present application.

[0043] In some embodiments, at least two first bosses may be provided on one side of one of the two adjacent plates close to the glue gap along the depth direction of the glue gap. The depth direction of the glue gap may refer to the thickness direction of the glue gap, such as Figure 5 As shown, the depth direction of the glue gap can be the direction indicated by arrow d. Figure 5 The first section 111 is taken as an example for description.

[0044] The first plate 111 may be provided with at least two first bosses in the direction indicated by the arrow d. The number of first bosses may include 2, 3, 4 or 5, etc. The embodiments of this specification do not impose any limitation on the number of first bosses. As an example, the first plate 111 may be provided with three first bosses in the direction indicated by the arrow d, namely 1111a, 1111b and 1111c. In some embodiments, at least one of the at least two first bosses may be a retractable boss. For example, the first bosses 1111a, 1111b and 1111c may all be retractable bosses. For another example, the first bosses 1111b and 1111c may be retractable bosses. For another example, the first boss 1111c may be a retractable boss. In some embodiments, the retractable boss may be retractable in any direction of the plane where the retractable boss is located. For example, the first boss 1111c may be retractable in the horizontal direction (such as Figure 5 For another example, the first boss 1111c can be extended in the vertical direction (eg, Figure 5 For another example, the first boss 1111c can be extended or retracted in a direction that is 45° to the horizontal dashed line on the plane where the first boss 1111c is located (eg, Figure 5 The device can be extended and retracted in the direction indicated by the arrow g in the figure.

[0045] In some embodiments, the gap adjustment device may include a gap depth adjustment device (not shown in the figure), which may be used to control the extension and retraction of the retractable boss to adjust the depth of the gluing gap. In some embodiments, the gap depth adjustment device can drive the retractable boss to extend to fit the side of the other plate of the two adjacent plates to adjust the depth of the gluing gap. In some embodiments, the gap depth adjustment device may include at least one second drive device (not shown in the figure). In some embodiments, the number of second drive devices may not be equal to the number of retractable bosses. In some embodiments, the number of second drive devices may be equal to the number of retractable bosses. In some embodiments, each second drive device may be used to drive one of the retractable bosses to extend and retract. Figure 5 As an example, the number of the second driving devices may include two, which are used to drive the first boss 1111b and the first boss 1111c to extend and retract. In some embodiments, the second driving device may be arranged on the side of the first plate 111. As an example, one second driving device drives the first boss 1111c to extend and retract to the same position as the first plate 111. Figure 2 The side of the second plate 112 is fitted, and the gap depth can be h1. For another example, a second driving device drives the first boss 1111c to shrink to be flush with the side of the first plate 111, and another second driving device drives the first boss 1111b to extend to be flush with the side of the first plate 111. Figure 2 The second plate 112 is fitted with the side surface of the second plate 112, and the gap depth can be h2. For another example, the two second driving devices respectively drive the first boss 1111b and the second boss 1111c to shrink to be flush with the side surface of the first plate 111, and the first boss 1111a and Figure 2 The side of the second plate 112 is fitted together, and the gap depth can be h3. <h2<h3。

[0046] In some embodiments, the second drive device may include a second drive unit and a second power device, and the second drive unit and the second power device may be transmission-connected, and the second drive unit may be used to move under the drive of the second power device, thereby driving the retractable boss to extend to fit the side of the other plate of the two adjacent plates to adjust the depth of the gluing gap. In a specific embodiment, the second power device may include a second motor, and the second drive unit may include at least two second telescopic rods. By controlling the elongation length of at least two second telescopic rods, a retractable boss can be adjusted to extend to fit the side of the other plate of the two adjacent plates. In some alternative embodiments, the second drive unit may also include but is not limited to a linear transmission mechanism, a hinge transmission mechanism, a gear rack transmission mechanism, a screw nut transmission mechanism, etc.

[0047] Figure 6 It is a schematic diagram of a glue tank according to some embodiments of the present application.

[0048] In some embodiments, the training device 100 may include a glue groove 140. The shape of the glue groove 140 may be the same as the shape of the glue gap 120. For example, the glue gap 120 is in a "cross" shape, and the glue groove 140 may also be in a "cross" shape. In some embodiments, the glue groove 140 can be installed in the glue gap 120. In some embodiments, the number of glue grooves 140 may include at least one. For example, the number of glue grooves 140 may include 1, 2, 3, 4, etc. In some embodiments, the widths of at least two glue grooves 140 may be the same or different. In some embodiments, the depths of at least two glue grooves 140 may be the same or different. Glue grooves 140 of different widths and / or depths can facilitate students to practice glueing in glue gaps of different widths and / or depths. When glueing, glue can be directly glued in the glue groove 140. When a student finishes practicing gluing, he can directly remove the glue tank 140 that has been glued and reinstall a new glue tank 140 to facilitate the next student to practice gluing quickly. This not only facilitates the cleaning of the glue tank 140, but also improves the efficiency of practical training.

[0049] In some embodiments, the material of the glue groove 140 may be the same as or different from the material of the four plates 110. As an example, the material of the glue groove 140 may include but is not limited to copper, aluminum, iron alloy, stainless steel, phenolic plastic, polyurethane plastic, silicone resin or acrylic resin.

[0050] In some embodiments, the training device 100 may include a gluing device (not shown in the figure). Glue is stored in the gluing device. Students can inject the glue in the gluing device into the gluing gap to practice the gluing operation. In some embodiments, a first sensor may be provided on the gluing device. The first sensor may be used to detect the glue level in the gluing device before and after a single gluing. For example, the first sensor may include an ultrasonic level meter. For another example, the first sensor may include a flow meter, which may directly detect the volume of glue used for a single gluing.

[0051] In some embodiments, the training device 100 may further include a processor (not shown in the figure). The processor and the first sensor may have a signal connection. The processor may be used to determine the volume of glue used for a single gluing according to the detection signal of the first sensor. For example, according to the shape of the gluing device, the processor may calculate the volume of glue used for a single gluing according to the level of glue in the gluing device before and after a single gluing detected by the first sensor. As an example, the gluing device is cylindrical, and the processor may calculate the volume of glue used for a single gluing according to the bottom area of ​​the gluing device and the level of glue before and after a single gluing.

[0052] In some embodiments, the training device 100 may further include a second sensor (not shown). The second sensor may be used to detect the width and depth of the glue gap. In some embodiments, the processor may determine the volume of the glue gap based on the detection signal of the second sensor. Figure 2 As shown, the four plates have the same shape and are equal in size. The width and depth of the first glue gap 121, the second glue gap 122, the third glue gap 123 and the fourth glue gap 124 are equal. The volume of the glue gap can be expressed as (the length of the first plate 111 + the length of the second plate 112 + the width of the first glue gap 121) * the width of the second glue gap 122 * the depth of the second glue gap 122 + (the length of the first plate 111 + the length of the third plate 113 + the width of the second glue gap 122) * the width of the third glue gap 123 * the depth of the third glue gap 123 - the width of the first glue gap 121 * the width of the second glue gap 122 * the depth of the second glue gap 122.

[0053] In some embodiments, the density can represent the ratio of the volume of glue used in a single gluing to the volume of the gluing gap. In some embodiments, the processor can be further used to determine the density of a single gluing according to the detection signal of the first sensor and the detection signal of the second sensor. In some embodiments, the training device 100 may also include a display (not shown in the figure). The display can be used to display the density of a single gluing. Teachers and students can know the quality of a single gluing directly based on the density displayed on the display, without waiting for the glue to solidify, removing the solidified glue and cutting it. By observing the bubbles inside the solidified glue and other subjective judgments on the quality of gluing, not only the training efficiency of exterior wall gluing can be improved, but also the teaching quality can be improved. In some embodiments, when a glue tank is used, the density can represent the ratio of the volume of glue used in a single gluing to the volume of the glue tank.

[0054] In some embodiments, the training device 100 may also include a storage device (not shown in the figure). In some embodiments, the storage device may store data information of different glue-applying devices. For example, the storage device may store the bottom area of ​​a cylindrical glue-applying device, etc. In some embodiments, the storage device may also store the volume of different glue-applying grooves. In some embodiments, the storage device may also store the density of each student's single glue-applying. In some embodiments, the storage device may include a large-capacity memory, a removable memory, a volatile read-write memory, a read-only memory (ROM), etc., or a combination of several of them. In some embodiments, the storage device may be connected to the processor for communication. For example, the processor may read the volume of the selected glue-applying groove. For another example, the processor may read the data of the selected glue-applying device (e.g., the bottom area of ​​the glue-applying device).
