Description

Technical Field

[0001] This invention relates to the field of air conditioning production and assembly technology, specifically to an assembly device for an air conditioner outdoor unit panel grille. Background Technology

[0002] The outdoor unit of an air conditioner is protected by an outer casing that covers its internal structure. To ensure airflow to the outdoor unit's fan, a grille is installed on the casing. This grille is detachably mounted to the casing via a snap-fit ​​mechanism on the outdoor unit's panel for easy access during maintenance. Currently, to improve assembly efficiency, automated assembly equipment has emerged that automatically snaps the grille onto the panel.

[0003] For example, Chinese Patent 202410050438.4 discloses an automatic assembly device for an air conditioner outdoor unit panel grille, which is configured in conjunction with an assembly line for placing and transporting panel grille sheet metal parts. The panel grille sheet metal parts include a panel and a grille, one of which is provided with a buckle and the other with a slot. The device includes a frame, a positioning mechanism, and a pressing mechanism. The frame is provided with an assembly area for receiving panel grille sheet metal parts transported by the assembly line. The positioning mechanism is installed on the frame and located in the assembly area, and is used to fix the position of the grille and the panel so that the buckle and the slot are aligned.

[0004] For the aforementioned existing technology, at least two alignment processes are required during the alignment of the grille and the panel. The first alignment involves initially placing the grille over the panel's mounting position to form the grille sheet metal part to be assembled. The second alignment involves positioning both the grille and the panel in a pressing station to ensure the clips and slots are aligned before pressing and fastening the grille onto the panel. Currently, the first alignment step is mainly performed manually, which is inefficient and prone to causing misalignment of the overlay position. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and to propose an assembly device for the grille of an air conditioner outdoor unit panel, which solves the technical problem that in the assembly of the grille and panel in the prior art, at least two alignments are required, and the first alignment is still done manually.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This invention provides an assembly device for an air conditioner outdoor unit panel grille, used for pressing the grille clips into the panel slots, comprising:

[0008] Assembly station;

[0009] A positioning mechanism includes a first positioning component and a second positioning component disposed on the assembly station.

[0017] In some embodiments, the assembly station is provided with a hovering component, which includes a telescopic mechanism and a hovering frame. The hovering frame is inclined downward along the grid conveying direction, with one side corresponding to the grid conveying line and the other side provided with a baffle. The telescopic end of the telescopic mechanism is connected to the baffle and is fixedly connected to the assembly station through a bracket, so that the hovering frame has a pending position at the assembly station and an interference-proof position away from the assembly station.

[0018] In some embodiments, the second positioning component has a notch corresponding to the suspension frame, so that when the second positioning component is switched to the suspension position, it can pass through the suspension frame and lift the grid to be assembled on the suspension frame with the grid positioning end.

[0019] In some embodiments, the pressing mechanism includes a first telescopic member, a second telescopic member, and a pressure head.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the 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 merely illustrative and not intended to limit the invention.

[0043] To address the technical problem that the assembly of grilles and panels requires at least two alignments, with the first alignment still requiring manual intervention, this invention provides an assembly device for air conditioner outdoor unit panel grilles. This device enables the first and second positioning components on a positioning mechanism at the assembly station to connect to the panel conveyor line and the grille conveyor line, respectively. This positions the panel and grille to be assembled at the assembly station, aligning them. Combined with a pressing mechanism, the positioned grille clips can be engaged with the panel clips in one step, completing the assembly of the grille and panel. This avoids manual positioning, reduces the probability of positioning misalignment, eliminates one manual positioning operation, streamlines the production line process, and improves assembly efficiency.

[0044] Please see Figure 1-9This invention provides an assembly device for an air conditioner outdoor unit panel grille. The assembly device is used to press the buckle 6a of the grille 6 into the slot 7a of the panel 7 for assembly. It 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 disposed 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 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 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 disposed 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 transported using a conveyor belt system. Instead of manually attaching the grille to the panel beforehand, the system directly separates into a panel conveyor line and a grille conveyor line. These two lines run parallel and converge at assembly station 1. The grilles are transported one after another to the grille positioning end of the second positioning component 22 and positioned at assembly station 1. The panels are transported to the panel positioning end of the first positioning component 21 and positioned at assembly station 1. The panels are positioned below the grilles, forming an upper and lower alignment, and the panel's slots are aligned with the grille's clips. Then, the pressing mechanism 3 drives the pressing end to press down the grille 6, which engages the clips with the slots, completing the assembly of the grille and the panel. The assembled air conditioner outdoor unit panel and grille are then transported to the subsequent production line along the panel conveyor line.

[0045] In this embodiment, it is used in conjunction with the panel conveyor line 8 and the grille conveyor line 9, requiring only one assembly station 1. When the grille 6 is conveyed to the assembly station 1, it is aligned with the panel 7 by the positioning mechanism 2, and then pressed down by the pressing mechanism 3 to form the engagement of the buckle 6a and the slot 7a. The manual pre-installation of the grille onto the panel is eliminated, avoiding errors caused by manual installation and saving labor. The traditional at least two positioning operations are combined into one, requiring only one assembly positioning of the grille and panel to align them and directly assemble them.

[0046] In one embodiment, please refer to Figure 1 , Figure 3 as well as Figure 6 In order to clamp and position the grille, the second positioning component 22 includes a positioning frame 221 and a flip-out gripper 222. The multiple grippers 222 are all disposed on the positioning frame 221 and form a clamping area for positioning the grille 6. They are used to support the grille 6 to be assembled at the lower edge and clamp all four sides of the grille 6 at the same time, so that the grille 6 to be assembled can be centered between the multiple grippers 222, thus forming clamping and positioning.

[0047] In this embodiment, please refer to Figure 10 In order to form a specific clamping and for subsequent release from the clamp, the gripper 222 has a bending point 222a. The gripper 222 consists of an upper frame and a lower frame, which is bent in the middle at the bending point 222a. The lower frame has an angle 222c with the bottom surface of the grid 6. The bending point is stuck on the bottom edge of the grid 6. The gripper 222 has an inclined surface 222b from top to the bending point 222a, forming an inclined surface that guides the grid to the center. That is, there are grippers 222 on all four sides of the grid. The inclined surface 222b of the gripper 222 guides the grid to slide towards the center of the clamping area and finally gets stuck on the bending point 222a of the gripper 222.

[0048] Optionally in this embodiment, in order to form a clamping support and avoid obstructing the fastening during the pressing and fastening assembly, the gripper 222 is rotatably connected to the positioning frame 221, and a torsion spring is provided between the gripper 222 and the positioning frame 221 to provide elastic support for the gripper 222 to be assembled with the grille 6. During the pressing action, the grille 6 moves down and pushes the lower half of the gripper 222, causing it to rotate and automatically disengage from the bottom of the grille 6.

[0049] This embodiment is optional; please refer to [the relevant documentation]. Figure 11 In order to form a clamping support and be more stable than an elastic support, the gripper 222 is rotatably connected to the positioning frame 221. A hydraulic push rod 222d is provided between the gripper 222 and the positioning frame 221. The two ends of the hydraulic push rod 222d are respectively hinged to the positioning frame 221 and the gripper 222. The extension and retraction of the hydraulic push rod 222d controls the gripper 222 to perform clamping and releasing actions.

[0050] In one embodiment, please refer to Figure 1 , Figure 3 , Figure 5 as well as Figure 7 To position the panel, the first positioning component 21 includes a conveying mechanism 211 and a socket positioning component 212. The conveying mechanism 211 is flush with the panel conveying line 8 and installed on the assembly station 1. It is used to convey the panel 7 to be assembled along the direction of the panel conveying line 8 and to position it by starting and stopping. The socket positioning component 212 is installed on the assembly station 1 and has a liftable positioning end. The positioning end corresponds one-to-one with the slot 7a. The panel 7 is transported to the position of the assembly station 1 by the panel conveying line 8, and the position is restricted by stopping the conveying. The conveying can continue when it is restarted. When the conveying is stopped, the positioning end is inserted into the slot 7a one by one in conjunction with the socket positioning component 212, which can further limit the position of the panel and restrict its position from shifting, making its position positioning more stable.

[0051] Understandably, the conveying mechanism 211 can be equipped with a position sensor for positioning, which can detect whether the panel has been conveyed to the designated position. Alternatively, a flip-up blocking mechanism can be used for positioning, blocking the panel at the designated position during conveying. When positioning is no longer needed, the blocking mechanism can be flipped away. A contact sensor can also be installed at the end to detect whether the panel is in contact with the blocking mechanism.

[0052] Furthermore, to create an empty area in the assembly area for the insertion positioning assembly 212 to rise and fall from bottom to top, and for the positioning end to be inserted into the slot 7a, the conveying mechanism 211 includes two conveyor belts 211a, which are located on both sides of the grid 6 to be assembled and are in contact with the panel 7 to be assembled. The insertion positioning assembly 212 is located in the empty area of ​​the grid 6 to be assembled. During the positioning operation, the positioning end is raised and positioned for insertion into the slot 7a. After assembly is completed, the positioning end is lowered to avoid interference with the movement of the assembly.

[0053] Understandably, to guide the panel in its positioning, an elastic support 213a, a guide plate 213b, and a fixing plate 213c are also provided. The elastic support 213a is fixed to assembly station 1 and has an elastically extendable end. The guide plate 213b is installed at this end and is parallel to the fixing plate 213c. The panel is L-shaped, and the downward-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 outward-bent portion, forming a gradually narrowing inlet. As the downward-bent portion of the panel enters the gap from the inlet / outlet, it helps to align the panel. Furthermore, because the elastic support 213a is elastically compressible, jamming is effectively prevented.

[0054] For further details, please refer to Figure 3 and Figure 5To provide a feedback mechanism for the engagement quality, the buckle 6a is checked for engagement after engagement, and its failure is assessed. The socket positioning assembly 212 includes a lifting platform 212a, an elastic telescopic block 212b, and a pressure sensor. The lifting platform 212a is mounted on the assembly station 1. The elastic telescopic block 212b is located at the telescopic end of the lifting platform 212a. The pressure sensor is located at the end of the elastic telescopic block 212b. During the engagement action, since the elastic telescopic block 212b is located inside the slot 7a, when the buckle 6a is pressed down and enters the slot 7a, it pushes the elastic telescopic block 212b to extend and retract. The pressure value fed back by the pressure sensor can indicate whether the engagement is complete and whether the buckle has broken or failed during the engagement process. In the failed state, the elastic telescopic block 212b is compressed to different degrees, resulting in different pressure feedback. When completely broken, the buckle 6a cannot push the elastic telescopic block 212b out of the slot 7a. The engagement status can be fed back based on the change in pressure value. When all are in the engaged position, the pressure values ​​fed back by each buckle are balanced and stable.

[0055] Additionally, the elastic telescopic block 212b consists of a sleeve, a telescopic block, and a spring. The telescopic block is slidably connected to the inside of the sleeve, and both ends of the spring are connected to the sleeve and the telescopic block, allowing the telescopic block to elastically extend and retract within the sleeve. A position sensor is installed inside the sleeve to detect the telescopic block's extension and retraction stroke. By compressing the telescopic block during its retraction stroke, feedback can also be provided on whether the latch is properly engaged. The telescopic block is the end that inserts into the slot 7a.

[0056] Understandably, in automated assembly, due to the mechanized snap-fit ​​assembly action, the quality of the snap-fit ​​varies from batch to batch, and it is difficult to ensure that all batches of grid snap-fits are not damaged under the same pressure. Therefore, in order to avoid snap-fit ​​breakage during assembly and to screen and provide feedback on it as soon as possible, the insertion positioning component 212 with a snap-fit ​​quality feedback mechanism can effectively achieve the above effect.

[0057] It should be noted that the lifting platform is composed of a top connecting platform plate made of hydraulic telescopic rods. The lifting platform is raised and lowered by extending and retracting the hydraulic telescopic rods.

[0058] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 In order to connect to the grid conveyor line and effectively dock with the second positioning component 22, the assembly station 1 is provided with a lifting mechanism 4, which has a lifting end that can be raised and lowered. The lifting end of the lifting mechanism 4 is connected to the second positioning component 22 and the pressing mechanism 3, driving the grid 6 to be assembled on the second positioning component 22 to cover the cover position on the panel 7 to be assembled, and to lift it up and away from the suspension position of the panel 7 to be assembled.

[0059] Understandably, if the conveyor line is used to transport the grid from top to bottom to the second positioning component 22, it can wait to be transported at the suspended position. For example, a robotic arm with suction cups can adsorb the grid and transport it to the second positioning component 22. This is a feasible implementation method. Alternatively, if a traditional conveyor belt is used, other intermediate mechanisms are needed to assist in stabilizing it. In this case, the suspension component 5 is needed for transfer.

[0060] Specifically, the assembly station 1 is equipped with a suspension component 5, which includes a telescopic mechanism 51 and a suspension frame 52. The suspension frame 52 is inclined downward along the conveying direction of the grille 6, with one side corresponding to the position of the grille conveyor line 9 and the other side equipped with a baffle 52a. The telescopic end of the telescopic mechanism 51 is connected to the baffle 52a and fixedly connected to the assembly station 1 through a bracket, so that the suspension frame 52 has a pending position on the assembly station 1 and an interference-proof position away from the assembly station 1. When the suspension frame 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 to the suspension frame 52, it slides along the inclined surface of the suspension frame 52 and its right end abuts against the baffle 52a, stopping on the suspension frame 52, waiting for the clamping of the second positioning component 22. During the lifting action of the lifting mechanism 4, the second positioning component 22 moves to the position of the suspension frame 52 and contacts the grille with each gripper 222. It continues to move upward, thereby lifting the grille and disengaging it from the suspension frame 52 to reach the suspended position. Because the positioning frame 221 has a notch 22a, it can pass through the suspension frame 52 during the lifting process to continue moving upward. After moving upward, the suspension frame 52 is moved away from below the second positioning component 22 by the telescopic mechanism 51. Then, controlling the second positioning component 22 to move downward switches to the closed position.

[0061] Furthermore, the second positioning component 22 is provided with a notch 22a corresponding to the suspension frame 52, so that when the second positioning component 22 is switched to the suspension position, it can pass through the suspension frame 52 and lift the grid 6 to be assembled on the suspension frame 52 with the grid positioning end.

[0062] Understandably, the lifting mechanism 4 consists of two sets. After the notch 22a is formed, the positioning frame 221 is divided into two separate parts. Each part is connected to the lifting end of the corresponding lifting mechanism 4 for synchronous lifting. The grippers 222 are evenly distributed on the two parts of the positioning frame 221. Correspondingly, the pressing mechanism 3 is also divided into two sets installed on the two parts of the positioning frame 221, and each set 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 uses a stepper motor driven screw guide pair, or other existing mature equipment with lifting function, as long as the lifting stroke can be controlled.

[0064] In order to avoid interference from the pressing mechanism during the lifting to the suspended position and clamping of 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 extends and retracts in a first direction, and the second telescopic member 32 has a telescopic end that extends and retracts in a second direction. The pressing head 33 is mounted on the telescopic end of the first telescopic member 31, and the first telescopic member 31 is mounted on the telescopic end of the second telescopic member 32. The first telescopic member 31 extends and retracts vertically, lifting the pressing head 33 above the positioning frame 221, while the second telescopic member 32 extends and retracts longitudinally, lifting the pressing head 33 away from the inside of the positioning frame 221. This avoids the pressing mechanism 3 obstructing the area of ​​the positioning frame 221 where the grille is housed.

[0065] Understandably, when pressure is required, the first telescopic member 31 and the pressure head 33 are moved to the area inside the positioning frame 221 to accommodate the grille by the second telescopic member 32, and then the pressure head 33 is pushed down by the first telescopic member 31 to press down the grille and form a snap-fit ​​assembly with the panel.

[0066] Furthermore, the pressure head 33 corresponds one-to-one with the buckle 6a, and the bottom is provided with an arc surface that matches the top chamfer of the grille 6.

[0067] It should be noted that the grid conveyor line 9 has guide baffles on both sides to align the grid and move it onto the suspension frame in a relatively accurate position, preventing excessive positional deviation. Furthermore, both the panel conveyor line 8 and the grid conveyor line 9 are equipped with position sensors that detect whether the panel or grid at the end has detached from the conveyor line, and start or stop the conveying based on the detection.

[0068] To better understand this invention, the following is combined with... Figures 1 to 9The technical solution of the present invention is described in detail as follows: The panel conveyor line 8 and the grid conveyor line 9 synchronously and linearly convey the panel and the grid; the grid conveyed by the grid conveyor line 9 moves to the suspension frame 52, is blocked by the baffle 52a, and is in a suspended position. At this time, the lifting mechanism 4 lifts the second positioning component 22 and moves it to the suspension frame 52. The gripper 222 fits the bottom edge of the grid to form a centered position, and continues to move upward to the suspended position. Then, the telescopic mechanism 51 moves the suspension frame 52 away from below the second positioning component 22; at the same time, the panel 7 moves to the conveyor belt 211a and, when it reaches the positioning position, stops the conveyor belt 211a and lifts the elastic telescopic block 212b to insert into the slot 7a, forming the fixed position of the panel 7. After the suspended frame 52 is moved away, the lifting mechanism 4 drives the second positioning component 22 to move down. During the lifting process, the pressing mechanism 3 moves down synchronously, switching the position to the cover position. The buckle 6a of the grille aligns with the slot 7a and contacts the panel 7. Through the extension and retraction 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 squeezing claw 222 flips and continues to press down on the grille until the buckle 6a is engaged with the slot 7a. After engagement, the squeezing elastic telescopic block 212b is pushed away from the slot 7a, providing feedback that the engagement is in place. The lifting platform 212a descends, moving the elastic telescopic block 212b away from the panel 7. The conveying mechanism 211 is activated to transport the assembled panel grille to the subsequent conveying line.

[0069] It should be noted that the assembly station 1 has a basic base for fixing the position of the suspension component 5 and the lifting mechanism 4; the second positioning component 22 and the pressing mechanism 3 in the positioning mechanism 2 are both installed on the lifting end of the lifting mechanism 4, located in the assembly station 1 area; in addition, the first positioning component 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 scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
