Description

Technical Field

[0001] This invention belongs to the field of dishwasher top cover assembly technology, and more specifically, relates to a dishwasher top cover assembly equipment and assembly method. Background Technology

[0002] The top cover assembly is an important component on the upper surface of electrical appliances such as washing machines, dishwashers, and dryers, serving multiple functions including aesthetics, load-bearing capacity, and waterproofing. The top cover assembly typically consists of a top cover frame, a wooden board, and positioning connectors, all of which are joined together using hot melt adhesive.

[0003] Traditionally, the assembly of the top cover assembly is done manually. First, a ring of glue is applied to the top cover frame, then a wooden board is placed on it, glue is applied to the board, and finally, the positioning connectors are placed at the glued positions on the board to complete the assembly. This manual assembly method is not only inefficient, but its accuracy is also greatly affected by the operator's skill level, easily leading to assembly errors and reduced product quality.

[0004] A search revealed Chinese Patent Application CN 208982425 U, which discloses a suction-operated adhesive-applying assembly device for the top cover of an integrated drum washing machine. This application includes a first support frame and a second support frame. The tops of the first and second support frames are respectively connected to a first support plate via first and second support columns. First and second buffer columns are respectively fixedly welded to the tops of the first and second springs. The tops of both the first and second buffer columns are fixedly connected to a second support plate, which is located within a through hole. Suction cups are evenly distributed on the top of the second support plate. This application utilizes suction cups to adsorb and position the washing machine top cover, thereby facilitating the adhesive application process.

[0005] For example, Chinese Patent Application No. CN107159519A discloses a glue applicator for a washing machine top cover. This application includes a frame, a positioning mold installed at the loading position of the frame to position and angle the waterproof sheet to be glued; a robotic arm installed on one side of the positioning mold, with a suction cup on the robotic arm for adsorbing the waterproof sheet from the positioning mold; a glue applicator nozzle installed at the glue applicator position on the frame, and a mechanical limiting block at the glue applicator position to limit the position of the waterproof sheet. This application solves the problem of inconsistent glue application, avoids errors, and improves work efficiency and product yield.

[0006] However, neither of the aforementioned documents took into account the interference that the machining errors and warping deformation of the top cover frame itself would cause to the assembly accuracy. Summary of the Invention

[0012] The positioning mechanism includes a working platform and a first positioning component, a second positioning component, and a third positioning component mounted on the working platform; the working platform is slidably mounted on the mounting base and can switch back and forth between different workstations; the three sets of positioning components are respectively used to position the outer frame, wooden board, and positioning parts of the top cover assembly;

[0013] The pressure-holding mechanism is used to grab the positioning component on the positioning mechanism and place it in the corresponding position on the wooden board, while simultaneously holding the assembled top cover assembly under pressure.

[0014] Furthermore, the first positioning component includes a positioning block and a first push block arranged opposite each other, and two second push blocks arranged opposite each other; wherein the two second push blocks move synchronously through a connecting unit, and the direction of movement is perpendicular to the direction of movement of the positioning block.

[0015] Furthermore, the connecting unit includes a connector with connecting rods hinged to both sides, and the connecting rods are connected to the second push block via a rotating shaft.

[0016] Furthermore, the second positioning component includes two third push blocks arranged opposite each other and two fourth push blocks arranged opposite each other. The two fourth push blocks are connected to the same driving source through their respective connecting plates. The driving source drives the four fourth push blocks on both sides to move synchronously, and the direction of movement is perpendicular to the direction of movement of the third push blocks.

[0017] Furthermore, the working platform includes an upper platform and a lower platform, wherein the first push block and the second push block are slidably disposed on the upper platform, and the connector and the connecting plate are slidably disposed on the lower platform.

[0018] Furthermore, the work platform is also provided with a first support platform, which consists of four rectangularly distributed support blocks.

[0019] Furthermore, the top of the support block and the side of the second push block are both provided with suction components.

[0020] Furthermore, the work platform is also provided with a second support platform, which is located in the area enclosed by four support blocks, and the second support platform is a lifting platform, with an adsorption component on the top of the lifting platform.

[0021] Furthermore, the pressure-holding mechanism includes a first pressure block and second pressure blocks located on both sides of the first pressure block, wherein the second pressure block is provided with an adsorption element.

[0054] refer to Figure 11 As shown, the top cover assembly of a dishwasher is generally composed of components such as an outer frame 91, a wooden board 92, and positioning parts 93, all of which are joined together using hot melt adhesive. Due to unavoidable processing errors during the manufacturing process of each component of the top cover assembly, the final assembly accuracy is affected. Furthermore, the outer frame 91 is generally made of ABS injection molding, and warping deformation may occur around the perimeter of the outer frame 91 during storage or transportation, which also affects assembly accuracy and overall aesthetics. This invention provides an assembly device for the top cover assembly, aiming to automate the assembly of the top cover assembly while reducing the impact of processing errors in the outer frame and warping deformation on assembly accuracy.

[0055] Additionally, it is worth noting that the centering mentioned in the following embodiments refers to centering along the center line of the outer frame 91 and the wooden board 92 (see reference). Figure 11 This is done to ensure that the center lines of the two parts are basically aligned, thereby reducing the impact of the component's own processing errors on the assembly accuracy between them. At the same time, the two sides of the center line correspond to the two sides of the outer frame 91 and the wooden board 92, and the two ends of the center line correspond to the two ends of the outer frame 91 and the wooden board 92.

[0056] The present invention will be further described below with reference to specific embodiments.

[0057] Example 1

[0058] like Figure 1 As shown, this embodiment of a dishwasher top cover assembly device includes a mounting base 1, on which a positioning mechanism 2 and a pressure holding mechanism 3 are provided. The positioning mechanism 2 is used to center and position each component of the top cover assembly to facilitate subsequent glue application and to provide a basis for precise assembly between the components.

[0059] The pressure holding mechanism 3 is used to grab the positioning part 93 located on the positioning mechanism 2 and place it on the corresponding position on the wooden board 92, while simultaneously holding the assembled top cover assembly under pressure.

[0060] In addition, the mounting base 1 is also equipped with a glue application mechanism 81 and a loading mechanism 82 on its side. The glue application mechanism 81 is used to apply glue to designated positions on the outer frame 91 and the wooden board 92; the loading mechanism 82 is used to place the various components of the top cover assembly into the corresponding positions on the positioning mechanism 2.

[0061] like Figure 2 , Figure 3As shown, the positioning mechanism 2 includes a working platform 21, which comprises an upper platform 211 and a lower platform 212 connected to each other. The lower platform 212 is slidably mounted on the mounting base 1 to facilitate the switching of the entire positioning mechanism 2 between different workstations.

[0062] The working platform 21 is equipped with a first positioning component 22, a second positioning component 23, and a third positioning component 24. The first positioning component 22 is used to center the outer frame 91; the second positioning component 23 is used to center the wooden board 92; and the third positioning component 24 is used to position the positioning element 93.

[0063] Specifically, refer to Figure 4 , Figure 5 As shown, the first positioning component 22 includes a positioning block 221, a first push block 222, and a second push block 223. The positioning block 221 is fixedly mounted on the upper platform 211 and serves to provide a positioning base for the outer frame 91.

[0064] The first push block 222 is disposed opposite to the positioning block 221 and is slidably disposed on the upper platform 211. The first push block 222 is connected to a drive source for driving the first push block 222 to be pushed from one end of the outer frame 91, so that the outer frame 91 moves toward the positioning block 221.

[0065] Two second push blocks 223 are arranged opposite each other. These second push blocks 223 move synchronously through a connecting unit, pushing synchronously from both sides of the outer frame 91 to center the outer frame 91. The second push blocks 223 are also slidably disposed on the upper platform 211, and their sliding direction is perpendicular to the sliding direction of the positioning block 221.

[0066] The connecting unit includes a connector 224, a connecting rod 225, and a rotating shaft 226. The connector 224 is slidably mounted on the lower platform 212. The connector 224 is generally T-shaped, with one end connected to a drive source and the connecting rod 225 hinged to both sides of the other end. The rotating shaft 226 is connected to the top surface of the connecting rod 225 near its end. The other end of the rotating shaft 226 passes through the upper platform 211 and connects to the bottom of the second push block 223. The upper platform 211 must have a slot for the rotating shaft 226 to pass through and move.

[0067] refer to Figure 6 , Figure 7 As shown, the second positioning component 23 includes a pair of third push blocks 231 and a pair of fourth push blocks 232. The two third push blocks 231 are located above the positioning block 221 and the first push block 222, respectively, and are used to push the wooden board 92 from both ends; and the third push blocks 231 are connected to a drive source.

[0068] The fourth push block 232 is positioned above the corresponding second push block 223 via a vertical plate, which is mounted on the connecting plate 233. The two connecting plates 233 are connected to the same drive source, which drives the two fourth push blocks 232 to push synchronously from both sides of the wooden board 92 for centering. The moving direction of the fourth push block 232 is perpendicular to the moving direction of the third push block 231. The connecting plate 233 is slidably mounted on the lower platform 212. The upper platform 211 also needs to have slots for the vertical plate to pass through and move.

[0069] like Figure 2 As shown, the third positioning component 24 includes several contoured positioning grooves 241, each corresponding to a different positioning element 93. The specific number and distribution of these grooves are determined based on the characteristics of the positioning elements 93. Specifically, in this embodiment, one positioning groove 241 is provided on one side of the positioning block 221, and two positioning grooves 241 are provided on one side of the first push block 222.

[0070] refer to Figure 8 As shown, the pressure-holding mechanism 3 includes a first pressure block 31 and second pressure blocks 32 located on both sides of the first pressure block 31. The first pressure block 31 can move up and down to maintain pressure on the wooden board 92.

[0071] The second pressing block 32 is provided with an adsorption element 6, and the second pressing block 32 can move in both horizontal and vertical directions to complete the transfer of the positioning element 93 and the pressure holding operation.

[0072] It should be noted that the sliding fit, the synchronous movement of the two fourth push blocks 232, the vertical movement of the first pressing block 31, and the vertical and horizontal movement of the second pressing block 32 in this embodiment can all be implemented using existing structures, and will not be described in detail here. Similarly, the glue dispensing mechanism 81, the feeding mechanism 82, and the drive source in this embodiment can be selected from existing equipment according to actual needs.

[0073] Example 2

[0074] To effectively reduce the impact of the outer frame's warping deformation on assembly accuracy. (Reference) Figure 4 As shown, in this embodiment of a dishwasher top cover assembly device, the sides of the second push block 223 are provided with suction components 6. Preferably, the suction component 6 is a vacuum suction cup, and the vacuum suction cup is embedded in the corresponding mounting surface to prevent interference with the outer frame 91.

[0075] This embodiment of a dishwasher top cover assembly device uses the adsorption member 6 to adsorb the outer frame 91 outwards, while the second pusher 223 presses the outer frame inwards, which can effectively correct the warping deformation of the outer frame 91 to ensure the accuracy of assembly.

[0076] Example 3

[0077] Based on the above embodiments, this embodiment provides a dishwasher top cover assembly device, wherein the working platform 21 is further provided with a first support platform 4 and a second support platform 5. The first support platform 4 is used to support the outer frame 91, and the second support platform 5 is used to support the wooden board 92.

[0078] Specifically, refer to Figure 3 , Figure 5 As shown, the first support platform 4 consists of four rectangularly distributed support blocks 41, which are used to support the four sides of the outer frame 91. At the same time, an adsorption element 6 is embedded in the top of the support block 41. The adsorption element 6 can ensure the stability of the connection between the outer frame 91 and the first support platform 4, and can also correct the warping deformation of the bottom of the outer frame 91 to a certain extent.

[0079] The second support platform 5 is located within the area enclosed by the four support blocks 41, and this second support platform 5 is a liftable platform. Similarly, the surface of the liftable platform is provided with suction elements 6 to ensure the stability of the connection between the wooden board 92 and the second support platform 5. In addition, the lifting mechanism of this liftable platform can adopt the structure of the prior art, which will not be described in detail here.

[0080] Example 4

[0081] refer to Figure 1 , Figure 9 As shown, the dishwasher top cover assembly equipment of this embodiment is further provided with an alignment platform 7 based on the above embodiment.

[0082] The alignment platform 7 includes an inclined platform plate 71 and two positioning plates 72 located on the platform plate 71, wherein the two positioning plates 72 are symmetrically distributed and the included angle is 90°.

[0083] When the wooden board 92 is placed on the alignment platform 7, due to the inclined setting of the platform plate 71, the wooden board 92, under its own gravity, eventually aligns its two adjacent sides with the corresponding positioning plates 72. This alignment platform 7 allows for pre-positioning of the wooden board 92, ensuring that it maintains a essentially uniform posture before being placed on the outer frame 91. This facilitates robot grasping and also benefits subsequent centering and positioning operations.

[0084] Example 5

[0085] This embodiment describes an assembly method for a dishwasher top cover assembly. The mounting base 1 is sequentially provided with a material loading station 11, a pressure holding station 12, and a glue application station 13. The specific steps are as follows:

[0086] S1. First, the positioning mechanism 2 stops at the loading station 11 and places the outer frame 91 on the first support platform 4. The three positioning parts 93 are located in the corresponding positioning grooves 241. Since the positioning grooves 241 are contoured, the three positioning parts 93 have completed the positioning operation at this time.

[0087] S2. Start the drive source of the first push block 222 to push from the end of the outer frame 91, so that the outer frame 91 is close to the positioning block 221; then, start the drive source of the connector 224, which drives the two second push blocks 223 to push synchronously from both sides of the outer frame 91 through the connecting rod 225 and the rotating shaft 226; after the outer frame 91 is centered, the second push block 223 and the adsorption component 6 on the support block 41 adsorb the outer frame 91 and correct the warping at the same time.

[0088] S3. Next, the positioning mechanism 2 moves to the glue application station 13 and uses the glue application mechanism 81 to apply glue to the outer frame 91. At the same time, the loading mechanism 82 transfers the wooden board 92 from the storage area to the alignment platform 7 for pre-positioning. After the glue application on the outer frame 91 is completed, the loading mechanism 82 transfers the wooden board 92 to the second support platform 5, at which time the second support platform 5 is in the raised state.

[0089] S4. Start the drive source of the second positioning component 23. At this time, the two third push blocks 231 push the two ends of the wooden board 92 synchronously, and the fourth push block 232 pushes the two sides of the wooden board 92 synchronously. After the centering operation of the wooden board 92 is completed, the adsorption component 6 of the second support platform 5 adsorbs the wooden board 92 and drives the wooden board 92 to move down synchronously, completing the bonding between the wooden board 92 and the outer frame 91.

[0090] S5, the glue-applying mechanism 81 applies glue to the gap between the wooden board 92 and the outer frame 91, and to three designated locations on the wooden board 92 (see reference). Figure 10 );

[0091] S6. Next, the positioning mechanism 2 moves to the pressure holding station 12, and the first pressure block 31 begins to press down; at the same time, the second pressure block 32 makes a corresponding displacement, adsorbs the positioning part 93 on the positioning mechanism 2, places the glue position corresponding to the wooden board 92, and then presses down.

[0092] S7. Finally, after the pressure holding operation is completed, the first pressure block 31 and the second pressure block 32 are reset, the positioning mechanism 2 returns to the loading station 11, and the assembled top cover assembly is removed.

[0093] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

Start the drive source of the second positioning component (23) to drive the third push block (231) and the fourth push block (232) to push from all sides of the wooden board (92); when the centering operation of the wooden board (92) is completed, the adsorption component (6) of the second support platform (5) adsorbs the wooden board (92) and drives the wooden board (92) to move down synchronously, completing the bonding between the wooden board (92) and the outer frame (91); S5, The glue-applying mechanism (81) applies glue to the wooden board (92); S6. After the glue is applied to the wooden board (92), the positioning mechanism (2) moves to the pressure holding station (12), and the first pressure block (31) begins to press down; at the same time, the second pressure block (32) adsorbs the positioning part (93) on the positioning mechanism (2) and moves it to the glue application position corresponding to the wooden board (92), and then presses down. S7. After the pressure holding operation is completed, the first pressure block (31) and the second pressure block (32) are reset, the positioning mechanism (2) returns to the loading station (11), and the assembled top cover assembly is removed.
