[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] In order to solve the technical problem that in the assembly of the grille and the panel, at least two alignments are required, and the first alignment is still carried out manually, the present invention provides an assembly device for the air conditioner outdoor unit panel grille, which can realize that at the assembly station, the first positioning component and the second positioning component on the positioning mechanism are respectively connected to the panel conveyor line and the grille conveyor line, so as to position the panel and the grille to be assembled in alignment at the assembly station. Cooperating with the pressing mechanism, the positioned grille buckle can be buckled with the panel slot at one time to complete the assembly of the grille and the panel, avoiding manual positioning operation, reducing the probability of positioning deviation, eliminating one manual positioning operation, streamlining the production line process and improving the assembly efficiency.

[0044] Please refer to Figures 1-9, the present invention provides an assembly device for the grille of the air conditioner outdoor unit panel. The assembly device for the grille of the air conditioner outdoor unit panel is used to press-fit the buckle 6a of the grille 6 and the slot 7a of the panel 7 for assembly, and includes an assembly station 1, a positioning mechanism 2, and a pressing mechanism 3; the positioning mechanism 2 includes a first positioning component 21 and a second positioning component 22 arranged on the assembly station 1. The first positioning component 21 has a panel positioning end for positioning the panel 7, which is used to connect to the panel conveyor line 8 and position the panel 7 to be assembled on the assembly station 1. The second positioning component 22 has a grille positioning end for positioning the panel 7, which is used to connect to the grille conveyor line 9 and align the grille 6 to be assembled with the panel 7 to be assembled; the pressing mechanism 3 is arranged on the assembly station 1 and has a pressing end for pressing the grille 6 to be assembled towards the panel 7 to be assembled. Both the panel and the grille are conveyed by conveyor belt-type conveyor lines. Instead of the method of manually pre-covering the grille onto the panel, it is directly divided into a panel conveyor line and a grille conveyor line. The two conveyor lines run in parallel and converge at the assembly station 1. Among them, the grilles are conveyed one by one to the grille positioning end of the second positioning component 22 and positioned at the assembly station 1, while the panels are conveyed to the panel positioning end of the first positioning component 21 and positioned at the assembly station 1. The panel is located below the grille to form upper and lower alignment, and the slot of the panel is aligned with the buckle of the grille. At this time, through the pressing mechanism 3, the pressing end is driven to press down the grille 6, and the buckle and the slot can be buckled to complete the assembly of the grille and the panel. Then, the assembled air conditioner outdoor unit panel and grille are conveyed along the panel conveyor line to the subsequent production line.

[0045] In this embodiment, when used in conjunction with the panel conveyor line 8 and the grille conveyor line 9, only one assembly station 1 is required. When the grille 6 is conveyed to the assembly station 1, it is aligned with the panel 7 through the positioning mechanism 2, and then pressed down through the pressing mechanism 3 to form the buckling of the buckle 6a and the slot 7a. The operation process of manually pre-covering the grille onto the panel is omitted, avoiding the covering error of manual operation and saving labor. The traditional at least two positioning operations are combined into one, forming only one assembly positioning for the grille and the panel, aligning them and directly performing the assembly.

[0046] In one of the embodiments, please refer to Figure 1 , Figure 3 and Figure 6 , in order to clamp and position the grille, the second positioning component 22 includes a positioning frame 221 and a flipable jaw 222. A plurality of the jaws 222 are arranged on the positioning frame 221 and form a clamping area for positioning the grille 6, which is used to support the lower edge of the grille 6 to be assembled and clamp the four sides of the grille 6 simultaneously, so that the grille 6 to be assembled can be centered between the plurality of jaws 222 to form clamping and positioning.

[0047] In this embodiment, please refer toFigure 10 To form a specific clamping and for subsequent release of the clamping, the jaw 222 has a bending point 222a. The jaw 222 is composed of an upper half frame and a lower half frame, and is bent at the middle with the bending point 222a. Moreover, the lower half frame of the jaw 222 has an included angle 222c with the bottom surface of the grille 6. The bending point is stuck on the bottom edge of the grille 6, and the jaw 222 has an inclined surface 222b from the top to the bending point 222a, forming an inclined surface for guiding the grille to be centered. That is, jaws 222 are provided on all four sides of the grille. The inclined surface 222b of the jaw 222 guides the grille to slide towards the middle of the clamping area and finally gets stuck on the bending point 222a of the jaw 222.

[0048] Optionally in this embodiment, to form a clamping support and avoid blocking the fastening during the downward pressing and fastening assembly, the jaw 222 is rotatably connected to the positioning frame 221, and a torsion spring is provided between the jaw 222 and the positioning frame 221 to provide an elastic support for the jaw 222 to the grille 6 to be assembled. During the downward pressing action, the grille 6 moves downward, pushing and squeezing the lower half of the jaw 222 to form a rotation and automatically release from the bottom of the grille 6.

[0049] Optionally in this embodiment, please refer to Figure 11 To form a clamping support and be more stable than the elastic support, the jaw 222 is rotatably connected to the positioning frame 221, and a hydraulic push rod 222d is provided between the jaw 222 and the positioning frame 221. Both ends of the hydraulic push rod 222d are hinged to the positioning frame 221 and the jaw 222 respectively. The clamping and unclamping actions of the jaw 222 are controlled by the telescopic movement of the hydraulic push rod 222d.

[0050] In one of the embodiments, please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 7 To position the panel, the first positioning assembly 21 includes a conveying mechanism 211 and a jacking positioning assembly 212. The conveying mechanism 211 is flush with the panel conveying line 8 and installed on the assembly station 1, and is used to convey the panel 7 to be assembled along the direction of the panel conveying line 8 and perform start-stop positioning. The jacking positioning assembly 212 is installed on the assembly station 1 and has a liftable positioning end. The positioning end corresponds to the card slots 7a one by one. The panel 7 is transported to the position of the assembly station 1 through the panel conveying line 8, and the position is restricted by stopping the conveying. Starting again can continue the conveying. When the conveying is stopped, in cooperation with the jacking positioning assembly 212, the positioning ends are inserted into the card slots 7a one by one, and then the position of the panel can be further limited to prevent its position from shifting, and its position positioning is more stable.

[0051] It is understandable that a position sensor can be provided on the conveying mechanism 211 for positioning, which can detect whether the panel is conveyed to the specified position. A flip-up blocking mechanism can also be used for positioning, blocking at the positioning position during conveying to form positioning, and when positioning is not required, the blocking mechanism can be flipped and moved away. Among them, a contact sensor can also be provided at the end, which can detect whether the panel contacts the blocking mechanism.

[0052] Furthermore, in order to form a vacant area in the assembly area for the jack positioning component 212 to lift up and down from bottom to top and for the positioning end to be inserted into the card slot 7a, the conveying mechanism 211 includes two conveyor belts 211a, and the two conveyor belts 211a are respectively located on both sides of the grille 6 to be assembled and are both in contact with the panel 7 to be assembled. The jack positioning component 212 is opposite to the position of the grille 6 to be assembled, that is, in the vacant area. During the positioning operation, the positioning end is lifted and inserted into the card slot 7a for positioning. After the assembly is completed, the positioning end is lowered to avoid interference with the movement of the assembled body caused by the positioning end.

[0053] It is understandable that in order to guide the panel to be properly positioned, elastic support members 213a, guide plates 213b, and fixing plates 213c are also provided. Among them, the elastic support member 213a is fixed on the assembly station 1. The elastic support member 213a has an elastically telescopic end portion, and the guide plate 213b is installed at this end portion and is parallel to the fixing plate 213c. Among them, the panel is L-shaped, and the downwardly bent portion of the panel is inserted into the gap between the guide plate 213b and the fixing plate 213c. The guide plate 213b has an outwardly bent portion, forming a gradually narrowing inlet. During the process of the downwardly bent portion of the panel entering the gap from the inlet, it plays a role in properly positioning the position. Moreover, since the elastic support member 213a can be elastically compressed, it can effectively avoid jamming.

[0054] Furthermore, please refer to Figure 3 and Figure 5, In order to have a snap - fit quality feedback mechanism to determine whether the snap - lock 6a is in the snap - fit position after snap - fitting and whether the snap - lock 6a fails, the jack positioning component 212 includes a lifting platform 212a, an elastic telescopic block 212b, and a pressure sensor. The lifting platform 212a is installed on the assembly station 1. The elastic telescopic block 212b is arranged at the telescopic end of the lifting platform 212a, and the pressure sensor is arranged at the end of the elastic telescopic block 212b. During the downward pressing and snap - fitting action, since the elastic telescopic block 212b is located inside the card slot 7a, when the snap - lock 6a is pressed downward and enters the card slot 7a, it will push the elastic telescopic block 212b to expand and contract. Through the pressure value feedback by the pressure sensor, it can be feedback whether the snap - fit is in place, and during the snap - fitting process, whether the snap - lock breaks or fails. In the failure state, the compression degree of the elastic telescopic block 212b is different, and the formed pressure feedback is different. When it is completely broken, the snap - lock 6a cannot push the elastic telescopic block 212b out of the card slot 7a. According to the change of the pressure value, the snap - fit state can be feedback. When all are in the snap - fit position, the pressure values feedback by each snap - lock are balanced and stable.

[0055] In addition, the elastic telescopic block 212b is composed of a sleeve, a telescopic block, and a spring. The telescopic block is slidably connected to the inner side of the sleeve. The two ends of the spring are connected to the sleeve and the telescopic block, enabling the telescopic block to elastically expand and contract inside the sleeve. And a position sensor is arranged inside the sleeve to detect the telescopic stroke of the telescopic block. By the extrusion stroke of the telescopic block when it contracts, it can also be feedback whether the snap - lock is snap - fit in place. The telescopic block is the end inserted into the card slot 7a.

[0056] It can be understood that in automated assembly, due to the mechanized snap - lock assembly action, under the change of the snap - lock quality batch, it is difficult to ensure that all batches of grille snap - locks are not damaged with the same pressing force. Therefore, in order to avoid the situation of snap - lock breakage during assembly and screen and feedback it in the first time, through the jack positioning component 212 with a snap - fit quality feedback mechanism, the above effects can be effectively achieved.

[0057] It should be noted that the lifting platform is composed of a platform plate connected to the top of a hydraulic telescopic rod. The hydraulic telescopic rod is used for telescoping to form the lifting of the lifting platform.

[0058] In one of the embodiments, please refer to Figure 1 、 Figure 3 and Figure 4 , in order to connect to the upper grille conveyor line and effectively dock with the second positioning component 22, a lifting mechanism 4 is arranged on the assembly station 1, which has a liftable lifting end. The lifting end of the lifting mechanism 4 is connected to the second positioning component 22 and the pressing mechanism 3, driving the grille 6 to be assembled on the second positioning component 22 to cover the covering position on the panel 7 to be assembled, and the suspended position of lifting and moving away from the panel 7 to be assembled.

[0059] It is understandable that if the conveyor line adopted is to convey from top to bottom onto the second positioning component 22, it will wait for conveyance at the suspension position. For example, a manipulator with a suction cup adsorbs and conveys the grille onto the second positioning component 22. This is a feasible implementation method. Additionally, a traditional conveyor belt can be used. If stability is required, other intermediate mechanisms are needed for assistance, and in this case, the hovering component 5 is required for transfer.

[0060] Specifically, a hovering component 5 is provided on the assembly station 1. The hovering component 5 includes a telescopic mechanism 51 and a hovering frame body 52. The hovering frame body 52 is inclined downward along the conveying direction of the grille 6. One side of it corresponds to the position of the grille conveyor line 9, and a baffle 52a is provided on the other side. The telescopic end of the telescopic mechanism 51 is connected to the baffle 52a and is fixedly connected to the assembly station 1 through a bracket, so that the hovering frame body 52 has a pending position corresponding to the assembly station 1 and an anti-interference position away from the assembly station 1. When the hovering frame body 52 is in the pending position, it is directly above the assembly station 1. At this time, when the grille on the conveyor belt is conveyed onto the hovering frame body 52, it slides along the inclined surface of the hovering frame body 52 and abuts its right end against the baffle 52a, and then stops on the hovering frame body 52, waiting to be clamped by the second positioning component 22. When the second positioning component 22 moves upward under the lifting action of the lifting mechanism 4 to the position of the hovering frame body 52, each clamping jaw 222 contacts the grille, and then continues to move upward, thereby lifting the grille and separating it from the hovering frame body 52 to reach the suspension position. Since there is a notch 22a on the positioning frame 221, it can pass through the hovering frame body 52 and continue to move upward during the lifting process. After moving upward, the hovering frame body 52 is driven by the telescopic mechanism 51 to leave below the second positioning component 22. Then, by controlling the second positioning component 22 to move downward, it can be switched to the covering position.

[0061] Furthermore, a notch 22a corresponding to the hovering frame body 52 is provided on the second positioning component 22. When the second positioning component 22 is switched to the suspension position, it can pass through the hovering frame body 52 and lift the grille 6 to be assembled on the hovering frame body 52 with the positioning end of the grille.

[0062] It is understandable that there are two groups of lifting mechanisms 4. After forming the notch 22a, the positioning frame 221 is divided into two separate parts, and each part is connected to the lifting end of the corresponding lifting mechanism 4 for synchronous lifting; the clamping jaws 222 are evenly distributed on the two parts of the positioning frame 221; correspondingly, the pressing mechanism 3 is also divided into two groups installed on the two parts of the positioning frame 221, and each group respectively has a first telescopic member 31, a second telescopic member 32, and a pressing head 33.

[0063] It should be noted that the lifting mechanism 4 can adopt a lead screw guide pair driven by a stepper motor, or other existing mature devices with lifting functions, as long as the lifting stroke can be controlled.

[0064] Among them, in order to avoid interference from the pressing mechanism during the lifting to the suspension position and the action of clamping the grille, the pressing mechanism 3 includes a first telescopic member 31, a second telescopic member 32 and a pressing head 33. The first telescopic member 31 has a telescopic end that can telescope along the first direction, the second telescopic member 32 has a telescopic end that can telescope along the second direction, the pressing head 33 is installed on the telescopic end of the first telescopic member 31, and the first telescopic member 31 is installed on the telescopic end of the second telescopic member 32. The first telescopic member 31 telescopes in the vertical direction to lift the pressing head 33 above the positioning frame 221, while the second telescopic member 32 telescopes longitudinally to lift the pressing head 33 away from the inner side of the positioning frame 221, thereby preventing the pressing mechanism 3 from blocking the area on the inner side of the positioning frame 221 where the grille is accommodated.

[0065] It can be understood that when pressing is required, the second telescopic member 32 is used to move the first telescopic member 31 and the pressing head 33 to the area on the inner side of the positioning frame 221 where the grille is accommodated, and then the first telescopic member 31 is used to push the pressing head 33 downward to press the grille and the panel to form a snap-fit assembly.

[0066] Furthermore, the positions of the pressing heads 33 correspond one by one to the positions of the buckles 6a, and the bottom is provided with an arc surface matching the top chamfer of the grille 6.

[0067] It should be noted that both sides of the grille conveyor line 9 are provided with guiding baffles to correct the position of the grille so that it moves to the hovering frame body and is in a relatively accurate position, which can avoid excessive position deviation. In addition, position sensors are provided on both the panel conveyor line 8 and the grille conveyor line 9 to detect whether the panel or grille at the end has left the conveyor line, and start and stop the conveyor according to the detection.

[0068] For a better understanding of the present invention, the following is combined with Figures 1 to 9The technical solution of the present invention will be described in detail: The panel conveyor line 8 and the grille conveyor line 9 linearly convey the panel and the grille synchronously; the grille conveyed by the grille conveyor line 9 moves to the hovering frame body 52 and is blocked by the baffle 52a and is in the hovering position. At this time, the lifting mechanism 4 lifts the second positioning assembly 22, moves to the position of the hovering frame body 52, and slews the bottom edge of the grille through the clamping jaw 222 to form a centered positioning, and continues to move up to the suspended position. Then, the telescopic mechanism 51 moves the hovering frame body 52 away from below the second positioning assembly 22; at the same time, the panel 7 moves onto the conveyor belt 211a, and when it reaches the positioning position, the conveyance of the conveyor belt 211a is stopped, and the elastic telescopic block 212b is lifted and inserted into the card slot 7a to form the positioning of the panel 7; after the hovering frame body 52 is moved away, the lifting mechanism 4 drives the second positioning assembly 22 to move down. During the lifting process, the pressing mechanism 3 moves down synchronously, and the position is switched to the covering position. The buckle 6a of the grille aligns with the card slot 7a and contacts the panel 7. Through the telescopic control of the first telescopic member 31 and the second telescopic member 32, the pressing head 33 is pressed onto the grille. Through the pressing action, the clamping jaw 222 is pushed to flip, and the grille is continuously pressed down until the buckle 6a is engaged with the card slot 7a, and after the engagement, the elastic telescopic block 212b is pushed away from the card slot 7a to provide feedback that the snap-fit assembly is in place; the lifting platform 212a descends to move the elastic telescopic block 212b away from the panel 7, and the conveying mechanism 211 is started to convey the assembled panel grille to the subsequent conveyor line.

[0069] It should be noted that the assembly station 1 has a basic base for fixing the position of the hovering assembly 5 and the lifting mechanism 4; the second positioning assembly 22 and the pressing mechanism 3 in the positioning mechanism 2 are both installed on the lifting end of the lifting mechanism 4 and are located in the area of the assembly station 1; in addition, the first positioning assembly 21 is directly installed on the base of the assembly station 1.

[0070] The specific embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
