Description

Technical Field

[0001] The present application relates to the technical field of air conditioner cover assembly, and in particular to a pasting and positioning device for a curved panel. Background Art

[0002] In the related art, the cold air of the air conditioner is delivered upward, and the cold air is restricted by the cover plate and blown out to the surrounding areas, so that the space can be filled with cold air. However, experiments have shown that during the refrigeration process, the cold air blows directly on the cover plate, and a lot of condensed water will be generated on the top of the cover plate. There is a risk of condensed water dripping, so it is necessary to install an electric auxiliary heating module for the cover plate to increase the surface temperature and prevent the generation of condensed water.

[0003] When installing the electric auxiliary heating module, the cover plate is composed of a top cover plate and a bottom cover plate, which are fixed together by double-sided tape. The cover plate is a three-dimensional structure, similar to the shape of a goose egg. When double-sided tape needs to be pasted on the bottom cover plate, it is difficult to operate without the assistance of tooling because its back is not flat, and the double-sided tape cannot be pressed and tightened after pasting.

[0004] At the same time, when installing the electric auxiliary heating module on the inside, there is no positioning structure and no reference to assist in the assembly of the electric auxiliary heating module, so the assembly efficiency is low. Moreover, when installing the electric auxiliary heating module, the installation position of the electric auxiliary heating module is extremely required. After the paste is offset, interference with the bottom cover plate will occur, causing arching and condensation failure. Summary of the invention

[0015] The height of the movable portion is higher than the height of the curved boss.

[0016] In one embodiment, the extended line of the sliding track of the movable part passes through the center of the base positioning tool;

[0017] The movable portion is adapted to the contact surface of the workpiece to be bonded.

[0018] In one embodiment, the curvature of the curved surface boss matches the curvature of the curved surface of the workpiece to be bonded;

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] The pasting positioning device used on the curved panel requires the production of a base positioning tool and a pasting piece positioning tool separately.

[0041] See also Figure 1 and Figure 2 , which is a schematic diagram of the front view and side view of the base positioning tooling shown in the embodiment of the present application, the base positioning tooling includes a base plate 10, a curved boss 20 and a workpiece limiting mechanism 30.

[0042] The bottom plate 10 includes three parts: a body portion of the bottom plate 10 , a middle hollow portion 101 and a mounting slot 102 .

[0043] The curved surface size of the curved surface boss 20 is determined according to the arc surface structure of the cover plate to be processed, and a positioning protrusion 201 is provided on the curved surface boss 20 .

[0044] The workpiece limiting mechanism 30 includes a fixed part and a movable part, wherein the movable part is connected to the fixed part, and the movable part is provided with a long waist-shaped hole, and the fixed part is connected by a sliding screw adapted to the long waist-shaped hole, so that the movable part can be set relative to the fixed part according to the long waist-shaped hole. The height of the movable part is higher than the curved boss.

[0045] Bakelite (i.e., phenolic plastic) has high mechanical strength, good insulation, heat resistance, and corrosion resistance, and is often used to manufacture electrical materials. Because the base positioning tooling as a base needs to have greater strength, Bakelite is used as a material to make a base plate 10 of suitable size. The base plate 10 is provided with a mounting slot for the curved boss and a mounting slot for the workpiece limiting mechanism, and four screw holes are opened diagonally on the mounting slot of the curved boss with the center point of the middle hollow as the origin, and the curved boss 20 is fixed to the base plate 10 through the four screw holes.

[0046] The middle opening of the base plate 10 is formed into a middle hollow 101, and a mounting slot 102 is opened around the middle hollow 101. The size of the mounting slot 102 is compatible with the structural size of the curved boss 20 and the moving size of the workpiece limiting mechanism 30, so as to facilitate the base plate 10 to fix the curved boss 20 and the workpiece limiting mechanism 30.

[0047] See also Figure 3 and Figure 4 , which is a schematic diagram of the front view and side view of the adhesive piece positioning tool shown in the embodiment of the present application, the adhesive piece positioning tool includes: an adhesive piece hollow area 401 and a positioning groove 404.

[0048] Because the structure of the adhesive positioning tooling is relatively complex, the adhesive positioning tooling is made by 3D printing. Figure 3 In the figure, there are provided an adhesive hollow area 401 and a central hollow area 402. When the adhesive positioning tooling cooperates with the base positioning tooling, the adhesive hollow area exposes the adhesive portion of the top cover plate. The adhesive hollow area matches the shape of the adhesive. Therefore, when processing the workpiece to be pasted, it is only necessary to paste the adhesive along the adhesive hollow area 401 to accurately position the workpiece and the double-sided tape.

[0049] The positioning protrusion 201 on the top surface of the curved boss is matched with the positioning groove 404 on the adhesive positioning tooling, and the positioning protrusion 201 can be embedded in the positioning groove 404. Such a positioning adaptation relationship can enable the top cover plate and the bottom cover plate to be processed to have a positioning structure when they are attached to the curved boss 20, so that the workpiece can be processed more accurately.

[0050] The adhesive positioning tool cooperates with the base positioning tool to process the top cover. The curved surfaces on the adhesive positioning tool and the base positioning tool that match the top cover can make the double-sided tape fit more tightly on the adhesive part and bear more force, while increasing the processing efficiency and improving the quality of the fit. It is used to paste auxiliary parts on the top cover plate. Through the pasting hollow area on the adhesive positioning tool, the auxiliary parts can be pasted accurately. The processed cover plate will not be interfered by the auxiliary parts, the positioning is accurate, and the condensation on the cover plate is qualified.

[0051] Embodiment 2

[0052] In the embodiments of the present application, examples are provided for describing the hollow areas, installation slots, limit blocks and positioning openings on the base positioning tooling and the adhesive piece positioning tooling.

[0053] refer to Figure 1 In the middle of the bottom plate 10 of the base positioning tooling, a circular hollow hole is opened, which is the middle hollow 101. The size is determined according to the arc surface structure of the top cover to avoid interference from the back of the top cover, and the middle hollow 101 can increase the versatility of workpiece processing.

[0054] refer to Figure 3 The central hollow area 402 of the adhesive positioning tool is adapted to the middle hollow 101 of the base positioning tool. The adhesive positioning tool itself is made of 3D printed material. Due to the existence of the central hollow area 402, the adhesive positioning tool is more flexible and can be bent to adapt to more arc sizes of the processed parts, thereby increasing the versatility of workpiece processing.

[0055] The bottom plate 10 is provided with a mounting slot 102, which is divided into a mounting slot for the curved boss and a mounting slot for the workpiece stopper. The mounting slot for the curved boss is opened around the middle hollow 101, with the center point of the middle hollow as the origin, and four screw holes are opened diagonally on the mounting slot for the curved boss, and the connecting line of the diagonal screw holes has an intersection angle of 90 degrees. The curved boss 20 is fixed to the bottom plate 10 along the mounting slot for the curved boss through the four screw holes.

[0056] The workpiece limiting mechanism is N limiting blocks arranged around the curved boss, where N is an integer greater than 1. The specific setting mode of the limiting blocks is to set the center of the base positioning tool as the center of the circle and to be arranged around the curved boss in a centrosymmetric manner.

[0057] In the second embodiment, N is 4. The limit block includes a fixed portion and a movable portion, the movable portion is connected to the fixed portion, the movable portion is provided with a long waist-shaped hole 301, the movable portion is connected to the fixed portion by a sliding screw matched with the long waist-shaped hole 301, and the screw fixes the fixed portion to the bottom plate 10.

[0058] When manufacturing the workpiece limiting mechanism 30, rubber is used as the material, and the inner side surface of the limiting block is designed to be an arc surface, so as to better cooperate with the side of the top cover and achieve a more accurate positioning effect. The rubber limiting block adopts a soft material, so that the top cover can be avoided from being scratched during positioning, and the appearance quality of the finished product can be ensured. The bottom of the movable part of the rubber limiting block should be higher than the height of the curved boss 20, so that it can play a full limiting role when the top cover to be processed cooperates with the base positioning tooling, and the movable part can slide on the track with the long waist hole as the slide groove without being restricted by the boss, which greatly increases the adaptability to the workpiece to be pasted, and can play a role in locking and positioning the workpieces of various sizes to be pasted. The opening of the workpiece limiting mechanism 30 is made in the shape of a long waist-shaped hole 301, and two long waist-shaped holes are opened on each limiting block, so that the sliding direction of the limiting block can be limited and the rotation can be restricted. The two long waist-shaped holes are used as sliding tracks for the sliding screws. The movable part of the limiting block can move in the parallel direction of the long waist-shaped hole 301. The extension line of the moving direction passes through the center of the base positioning tooling to control the distance from the rubber workpiece limiting mechanism 30 to the curved boss 20 and adjust the position of the rubber limiting block. The hole position of the long waist-shaped hole 301 is determined according to the selected limit block center distance.

[0059] The pasting hollow area 401 of the pasting piece positioning tooling matches the shape of the electric auxiliary heating module to be pasted, so that the electric auxiliary heating module can be positioned and pasted on the bottom cover plate by pasting the hollow area 401 during the processing. At the same time, the pasting piece positioning tooling is also provided with a positioning opening 403. The positioning opening 403 does not completely play a positioning role for the pasting piece positioning tooling on the base positioning tooling, because after the movable part of the workpiece limiting mechanism 30 slides and locks the workpiece to be pasted, it does not necessarily lock the pasting piece positioning tooling, so the positioning opening 403 plays more of a role in coordinating with the shape of the base positioning tooling, facilitating the pasting piece positioning tooling to better fit the workpiece to be pasted and the base positioning tooling. The number N of positioning openings corresponds to the number N of workpiece limiting mechanisms 30, so in this embodiment, the number of positioning openings 403 is also 4, and the edge of the positioning opening 403 is curved, which is convenient for fitting with the movable part of the workpiece limiting mechanism 30 to achieve a laterally symmetrical positioning effect. At the same time, the adhesive piece positioning tooling is provided with a positioning groove 404, and the positioning protrusion 201 can be embedded in the positioning groove 404, so through the cooperation of the positioning groove 404 and the positioning protrusion 201, a positioning effect can be played. Through the above positioning and limiting mechanism, the adhesive piece positioning tooling can be positioned more accurately relative to the base positioning tooling.

[0060] The base positioning tool and the adhesive piece positioning tool are provided with hollow areas, which increase the versatility of the tool by increasing the adaptability to workpieces of various sizes to be pasted. The installation slot 102 is provided on the bottom plate 10 of the base positioning tool, so that the curved boss 20 and the workpiece limiting mechanism 30 can be better installed. By sliding the movable part of the limiting block and changing its distance to the center of the base positioning tool, the placement space of the workpiece to be pasted can be adjusted, so that the versatility of the base positioning tool is increased, and workpieces of different sizes to be pasted can be positioned. The setting of the positioning opening 403 allows the adhesive piece positioning tool to better adapt to the base positioning tool, because the positioning opening 403 of the adhesive piece positioning tool can be staggered with the workpiece limiting mechanism 30, so that the existence of the raised workpiece limiting mechanism 30 does not affect the adhesive piece positioning tool from being attached to the base positioning tool.

[0061] Embodiment 3

[0062] In the embodiments of the present application, the detachability of the curved boss and the movable part mechanism of another workpiece limiting mechanism are exemplified.

[0063] The curved boss 20 on the base positioning tool is fixed to the corresponding mounting slot 102 by screws, so the curved boss 20 is detachably connected to the base plate 10. Although there is a hollow 101 in the middle, when processing curved panels with different curvatures, curved bosses 20 with different curvatures are required to adapt. The curved boss 20 of the pasting positioning device on the base plate includes at least two curvature models. By disassembling and replacing the curved boss 20, it can adapt to more curved surface sizes of workpieces to be pasted, increasing the versatility of the base positioning tool.

[0064] The workpiece limiting mechanism 30 includes a fixed part and a movable part. The movable part is a detachable part while being movable and positioned. In this embodiment, a spring slider is used as the movable part. A notch is provided on the fixed part as a sliding track of the spring slider, which is convenient for limiting the sliding of the spring slider thereon. The telescopically movable spring slider is arranged around the curved boss, and N spring sliders are symmetrically centered toward the positioning center of the base positioning tooling. A retaining spring is provided on the spring for positioning, and the height of the spring slider is higher than the height of the curved boss, which is convenient for positioning the workpiece to be pasted. The N is an integer greater than 1. The movable part of the spring slider can flexibly position the workpiece to be pasted, which is more convenient for the operator to operate.

[0065] Embodiment 4

[0066] In the embodiment of the present application, a detailed description of the operation method of the pasting positioning device for the curved panel is provided. Fig.10 The pasting and positioning device for a curved panel is exemplified using a flow chart.

[0067] 1001. Fix the bottom cover with the limit block of the base positioning tooling and stick the double-sided tape.

[0068] First, slide the movable part of the rubber workpiece limiting mechanism 30 to increase the distance between the movable part of the rubber workpiece limiting mechanism 30 and the curved boss 20 so that there is enough space to place the bottom cover plate. Figure 7The non-convex surface of the bottom cover in the side view, facing downward and facing the curved boss, is placed on the base positioning tooling, and the distance between the active part of the rubber workpiece limiting mechanism 30 and the curved boss 20 is reduced. Check whether the active parts of the four rubber workpiece limiting mechanisms 30 can effectively limit the position, and then slightly clamp the bottom cover, that is, the position of the active part of the rubber workpiece limiting mechanism 30 can fully limit the horizontal movement of the bottom cover without affecting the up and down movement of the bottom cover, that is, the fit with the base positioning tooling. At the same time, the positioning protrusion 201 on the curved boss 20 cooperates with the positioning block on the bottom cover, so as to avoid looseness and cause the adhesive to deviate during the pasting process. When pasting the double-sided adhesive, because the curved surface of the curved boss 20 of the base positioning tooling cooperates well with the fitting surface of the bottom cover, the double-sided adhesive can be fully stressed, and the hand is pressed hard to ensure that the adhesive is firmly attached. At this time, the curved boss 20 plays a supporting role, so that the double-sided adhesive can be tightly attached to the fitting surface of the bottom cover.

[0069] 1002. Remove the bottom cover plate, fix the top cover plate with the limit block of the base positioning tooling, and then install the adhesive positioning tooling on the top cover plate.

[0070] Specifically, the movable part of the rubber workpiece limiting mechanism 30 is slid to release the positioning of the bottom cover plate, and then the bottom cover plate is removed. The movable part of the rubber workpiece limiting mechanism 30 is slid to expand the distance between the movable part of the rubber workpiece limiting mechanism 30 and the curved boss 20, so that there is enough space between them to place the top cover plate, and the top surface of the top cover plate, i.e. Fig. 9 The curved surface with the inner recess in the side view of the top cover plate is placed on the base positioning fixture with the surface facing downward and facing the curved boss. The inner recess is aligned with the positioning protrusion 201 on the curved boss 20, and the distance between the movable part of the rubber workpiece limiting mechanism 30 and the curved boss 20 is reduced. After checking whether the four rubber workpiece limiting mechanisms 30 can effectively limit the position, the top cover plate is clamped, and the movable part of the limiting block is adjusted to fix it, that is, the position of the workpiece limiting mechanism 30 can effectively limit the horizontal movement of the top cover plate. Relative to the top surface, the other side of the top cover plate is the adhesive surface. After the top cover plate and the base positioning fixture are firmly matched, the adhesive positioning fixture is assembled to the base positioning fixture with the positioning groove 404 facing upward, the positioning protrusion 201 is aligned, and the adhesive surface facing the top cover plate is assembled.

[0071] 1003. Paste the electric auxiliary heating module on the top cover plate through the pasting hollow area on the pasting positioning tooling that matches the pasting piece.

[0072] Process the top cover plate, and accurately paste the electric auxiliary heating module to the adhesive surface of the top cover plate. At this time, the top cover plate is fitted between the base positioning tooling and the adhesive positioning tooling. Because the adhesive positioning tooling has hollow areas 401 and 402, the area on the top cover plate where the electric auxiliary heating module needs to be pasted is just exposed through the adhesive hollow area 401. When pasting the electric auxiliary heating module, align the electric auxiliary heating module with the exposed area and directly use double-sided tape to paste it. When processing workpieces with different curvatures to be pasted, after the adhesive positioning tooling is pasted on the workpiece, because the 3D printed material itself is relatively soft and has a central hollow area 402, the curvature of the adhesive positioning tooling itself can be increased within its own deformation range according to the workpiece to be pasted. The curvature makes it fit the workpiece better and the pasting of the adhesive is better completed. In this way, the adhesive positioning tooling has greater versatility.

[0073] The above steps complete the positioning of the electric auxiliary heating module on the top cover and the pasting of the double-sided tape. Next, you only need to remove the adhesive positioning tooling, align the bottom cover with the top cover, and stick it. Because the top and bottom cover plates are both positioned and pasted with double-sided tape by the base positioning tooling, the aligned positioning centers are consistent, so the relative center positions of the double-sided tapes are also accurately corresponding, so there is no need to spend manual alignment, solving the problem of inaccurate pasting of the electric auxiliary heating module.

[0074] 1004. Remove the adhesive positioning tooling, align the bottom cover plate with the top cover plate and bond them together.

[0075] You can refer to Figure 6 and Figure 8 The front view of the top cover and the bottom cover is used to complete the lamination of the cover. The curved boss 20 of the base positioning tool is used as a force support. The top cover and the bottom cover are pressed tightly, and then the movable part of the rubber workpiece limiting mechanism 30 is slid and released to remove the processed cover. In this way, the processing of the electric auxiliary heating module of the cover is completed. Through this set of pasting and positioning devices, not only can the lamination and positioning of the electric auxiliary heating module be accurate, so that the condensation of the cover is qualified, but also the double-sided adhesive can be more tightly fitted and more fully stressed, which increases work efficiency and improves the quality of lamination.

[0076] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed to help understand the method and core idea of ​​the present application. At the same time, for those of ordinary skill in the art, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
