The panel grille sheet metal parts 300 include a panel 301 and a grille 302. One of the panel 301 and the grille 302 is provided with a buckle 3020, and the other is provided with a slot 3010. The device includes a frame 10, a positioning mechanism 20 and a pressing mechanism 30; the frame 10 is provided with an assembly area, and the assembly area is used to receive the panel grille sheet metal parts 300 transported by the assembly line 200. The panel grille sheet metal part 300; the positioning mechanism 20 is installed on the frame 10 and is located in the assembly area, and the positioning mechanism 20 is used to fix the position of the grille 302 and the panel 301 so that the buckle 3020 and the slot 3010 remain aligned; the pressing mechanism 30 is installed on the frame 10 and is located in the assembly area, and the pressing mechanism 30 is used to press the grille 302 toward the panel 301 so that the buckle 3020 and the slot 3010 are buckled.

[0050] In this embodiment, the automatic assembly device 100 for the panel grille of the air conditioner outdoor unit is arranged together with the assembly line 200. The assembly line 200 is used to place and transport the panel grille sheet metal parts 300 to be assembled. When the conveyor belt on the assembly line 200 moves, the panel grille sheet metal parts 300 are driven to move. Figure 3 and Figure 4 As shown, the panel grille sheet metal part 300 is composed of a panel 301 and a grille 302. The panel grille sheet metal part 300 is manually assembled on the previous production line with the panel 301 at the bottom and the grille 302 at the top. A buckle 3020 is provided on one of the panel 301 and the grille 302, and a slot 3010 is provided on the other. In this embodiment, the panel grille sheet metal part 300 is formed as shown in FIG. Figure 4In the structure shown, a slot 3010 is provided on the panel 301, and a buckle 3020 is provided on the grille 302. In other embodiments, the buckle 3020 may be provided on the panel 301 and the slot 3010 may be provided on the grille 302. In the panel grille sheet metal part 300 to be assembled, the buckles 3020 on the grille 302 are not engaged with the slots 3010 on the panel 301, that is, the panel grille sheet metal part 300 is a semi-assembled component in which the buckles 3020 of the grille 302 are not engaged with the slots 3010 of the panel 301. The panel grille sheet metal part 300 is placed on the assembly line 200 and transported by the assembly line 200. The frame 10 is the basic frame of the entire device, which is usually made of metal. The assembly area of ​​the frame 10 is the main space area for assembling the panel grille sheet metal part 300. The assembly line 200 can be installed under the frame 10, and a part of it is in the assembly area, and the panel grille sheet metal parts 300 produced by the previous production line can be transported to the assembly area of ​​the frame 10 for assembly. The positioning mechanism 20 is installed on the frame 10 and is located in the assembly area. It can adjust and fix the positions of the grille 302 and the panel 301 in the panel grille sheet metal parts 300 transported to the assembly area, so that the buckle 3020 on the grille 302 and the card slot 3010 on the panel 301 are kept in the corresponding position of the assembly area. The positioning mechanism 20 can specifically adopt the structure of the grille 302 and the panel 301 or the structure of clamping the grille 302 and the panel 301 to fix the position of the grille 302 and the panel 301. The pressing mechanism 30 is installed on the frame 10 and is located in the assembly area. The pressing mechanism 30 can press the grille 302 toward the panel 301, so that the buckle 3020 on the grille 302 is completely buckled into the slot 3010 on the panel 301, thereby completing the assembly of the grille 302 and the panel 301, so that the panel grille sheet metal part 300 changes from a semi-assembled state to a fully assembled state. The pressing mechanism 30 can specifically adopt a telescopic cylinder to perform telescopic pressing. A position sensor is provided on the telescopic cylinder to detect whether the pressing action is in place. The pressing mechanism 30 can also adopt other mechanisms that can realize pressing the grille 302. In a specific implementation, the entire device can use PLC as a controller, and the operation of the assembly line 200, the positioning mechanism 20 and the pressing mechanism 30 can be controlled by programming the PLC. The previous production line places the panel grille sheet metal 300 on the assembly line 200, and the PLC controls the movement of the assembly line 200 to transport the panel grille sheet metal 300 to the assembly area of ​​the rack 10. A sensor can be installed in the assembly area of ​​the rack 10 to obtain the position information of the panel grille sheet metal 300. The sensor can use a photoelectric switch, etc. The PLC can determine whether the panel grille sheet metal 300 has reached the correct position in the assembly area through the signal sent back by the sensor.When the sensor detects that the panel grille sheet metal 300 has reached the correct position, the PLC controls the assembly line 200 to stop moving, and then controls the positioning mechanism 20 to position the panel grille sheet metal 300. The positioning mechanism 20 fixes the position of the grille 302 and the panel 301, so that the buckle 3020 on the grille 302 is aligned with the slot 3010 on the panel 301. Then the PLC controls the pressing mechanism 30 to press the grille 302 toward the panel 301, so that the buckle 3020 on the grille 302 is buckled into the slot 3010 on the panel 301, completing the assembly of the grille 302 and the panel 301. At this time, the grille 302 and the panel 301 are completely assembled into a whole. Finally, the PLC controls the assembly line 200 to continue moving, and transports the assembled panel grille sheet metal 300 products in the assembly area to the production line of the next process. At the same time, the panel grille sheet metal 300 that has not been assembled before continues to be transported by the assembly line 200 and flows into the assembly area for further assembly. In this cyclic operation, the automated assembly production of the grille 302 and the panel 301 is realized.

[0051] In this embodiment, the panel grille sheet metal to be assembled is transported to the assembly area of ​​the frame through an assembly line, a positioning mechanism is used to fix the position of the panel and the grille, so that the buckles on the grille are aligned with the slots on the panel, and a pressing mechanism is used to press the grille toward the panel so that the buckles on the grille are engaged with the slots on the panel, thereby realizing automatic assembly of the grille and the panel. Compared with manual assembly, the assembly efficiency is effectively improved to meet the production needs of actual products.

[0052] In one embodiment, referring to Figure 5The frame 10 includes an assembly table 11 and a tripod 12. The tripod 12 is fixed to the downward side of the assembly table 11. The tripod 12 is connected to the lower side of the assembly table 11 to support the assembly table 11. The assembly table 11 is arranged above the assembly line 200. The pressing mechanism 30 and the positioning mechanism 20 are both installed on the assembly table 11. The assembly table 11 and the assembly line 200 are spaced a certain distance apart to define the assembly area. Specifically, the assembly table 11 is a platform structure with a certain area. It is horizontally arranged above the assembly line 200 and maintains a certain distance from the assembly line 200 in the vertical direction. The assembly area is the space area between the assembly line 200 and the assembly table 11. The tripod 12 is fixedly connected to the downward side edge of the assembly platform 11 to support the assembly platform 11. The tripod 12 can also be respectively arranged on the left and right side edges of the assembly platform 11, so that the support can be more stable. In this embodiment, the tripod 12 is fixed to the downward side edge of the assembly platform 11 to facilitate the installation of the assembly line 200. The tripod 12 can be designed to be integrated with the chassis, and controller components such as PLC can be installed in the chassis. In actual production, the assembly line 200 transports the panel grille sheet metal 300 to the assembly area under the assembly table 11, and the positioning mechanism 20 fixes the position of the grille 302 and the panel 301 in the panel grille sheet metal 300 in the assembly area between the assembly line 200 and the assembly table 11, so that the buckle 3020 of the grille 302 and the slot 3010 of the panel 301 maintain an aligned state, and then the grille 302 is pressed toward the panel 301 by the pressing mechanism 30, so that the buckle 3020 of the grille 302 is engaged in the slot 3010 of the panel 301 to complete the assembly. The overall structure is simple and the assembly of the panel grille sheet metal 300 is more stable.

[0053] In one embodiment, referring to Figure 1 , Figure 6The pressing mechanism 30 includes a first telescopic pressing module 31 and a second telescopic pressing module 32, the first telescopic pressing module 31 and the second telescopic pressing module 32 are arranged at a distance on the downward side of the assembly platform 11, wherein the first telescopic pressing module 31 and the second telescopic pressing module 32 are used to perform telescopic pressing on the upward side surface of the grille 302 from top to bottom and tilted toward each other, so that the buckle 3020 is buckled with the slot 3021. In a specific implementation, the first telescopic pressing module 31 and the second telescopic pressing module 32 adopt the same structure, the first telescopic pressing module 31 and the second telescopic pressing module 32 are fixed at a distance on the downward side of the assembly platform 11, and the two are tilted toward each other at a certain angle, and the distance and tilt angle between the two can be determined according to the overall size of the panel grille sheet metal 300, and the first telescopic pressing module 31 and the second telescopic pressing module 32 should be able to maintain a certain distance from the panel grille sheet metal 300 in the vertical direction. When assembling the panel grille sheet metal 300, the first telescopic pressing module 31 and the first telescopic pressing module 31 are telescopically pressed toward the upward side surface of the grille 302 at an angle toward each other. The upward side surface of the grille 302 is passively pressed toward the panel 301 by the force of both the first telescopic pressing module 31 and the second telescopic pressing module 32. The buckle 3020 on the grille 302 is buckled into the slot 3010 on the panel 301, thereby completing the assembly, and the assembly is more stable and reliable.

[0054] Further, refer to Figures 9 to 11The first telescopic pressing module 31 and the second telescopic pressing module 32 both include a first telescopic driving member 310 and a pressing member 311, wherein the first telescopic driving member 310 is fixedly disposed on the downward side of the assembly platform 11, and the pressing member 311 is connected to the first telescopic driving member 310, wherein the first telescopic driving member 310 is used to drive the pressing member 311 to telescope and press from top to bottom in the vertical direction toward the upward side of the grille 302, so that the buckle 3020 is buckled in the slot 3010. In the specific implementation, the fourth driving member adopts a telescopic cylinder. The main part of the telescopic cylinder can be fixed on the downward side of the assembly platform 11, or an opening can be opened on the assembly platform 11 to install the main part of the telescopic cylinder. The pressing member 311 is fixed at the end of the telescopic shaft of the telescopic cylinder. The position of the telescopic cylinder corresponds to the position on the grille 302 that needs to be pressed. When the assembly is actually performed, the telescopic cylinder drives the pressing member 311 to move vertically from top to bottom toward the planned pressing point on the surface of the upper side of the grille 302, so that the pressing member 311 presses on the pressing point on the surface of the grille 302. Usually, the pressing point is the position close to the center of the surface of the upper side of the grille 302. The telescopic cylinder is provided with a position sensor, which can detect whether the telescopic shaft is telescoped in place, so as to press the grille 302 in place. After the grille 302 is pressed, the buckle 3020 on the grille 302 is completely buckled into the slot 3010 on the panel 301, completing the assembly of the grille 302 and the panel 301. In actual design, the pressing member 311 can be designed with a relatively soft or elastic material, or a layer of buffer can be provided on the side in contact with the surface of the grille 302 to prevent the pressing plate 2102 from deforming the surface of the grille 302 and affecting the product appearance. If the pressing area of ​​the pressing member 311 is too small, it will also affect the pressing effect, so the part of the pressing member 311 used for pressing can be designed accordingly according to the area of ​​the upper side of the grille 302.

[0055] In one embodiment, referring to Figure 1 and Figure 6The positioning mechanism 20 includes a grille holding mechanism 21, which is disposed on the assembly platform 11 and above the assembly area, wherein the grille holding mechanism 21 is used to press the grille 302 so that the buckle 3020 and the slot 3010 are aligned. In a specific implementation, since the buckle 3020 of the grille 302 and the buckle 3020 of the panel 301 in the plate grille 302 assembly are not aligned very precisely, in order to keep the grille 302 in the correct assembly position on the panel 301, the position of the grille 302 is adjusted by the grille holding mechanism 21, and the grille holding mechanism 21 presses the grille 302 so that the grille 302 is pressed and passively adjusted in position, so that the buckle 3020 on the grille 302 and the slot 3010 on the panel 301 are more accurately aligned. When the pressing mechanism 30 presses the grille 302 , the buckles 3020 on the grille 302 can be accurately engaged with the slots 3010 on the panel 301 .

[0056] Further, refer to Figures 6 to 8 The grille holding mechanism 21 includes a vertical telescopic module 210 and an inclined telescopic module 211 which are spaced apart on the assembly platform 11. The vertical telescopic module 210 and the inclined telescopic module 211 are both located above the assembly line 200 in the assembly area, wherein the vertical telescopic module 210 is used to vertically telescope from top to bottom toward one side of the top of the grille 302 to press against the grille 302, and the inclined telescopic module 211 is used to obliquely telescope from top to bottom toward the other side of the top of the grille 302 to press against the grille 302. In a specific implementation, the vertical telescopic module 210 is installed on the downward side of the assembly platform 11, located above the assembly line 200 in the assembly area, and can vertically press against the upward side of the grille 302 above the panel 301 from top to bottom by telescoping in the vertical direction. The inclined telescopic module 211 is also installed on the side of the assembly table 11 facing downward, located above the assembly line 200 in the assembly area. The inclined telescopic module 211 is spaced apart from the vertical telescopic module 210. The inclined telescopic module 211 also presses the grille 302 above the panel 301 by telescoping, but the telescopic side of the inclined telescopic module 211 is inclined relative to the horizontal plane, and it presses the grille 302 from top to bottom in an inclined manner toward the other side facing upward by telescoping. The vertical telescopic module 210 and the inclined telescopic module 211 press on the grille 302 at different positions, so that the grille 302 can be kept in the correct assembly position, and the buckle 3020 on the grille 302 can be accurately aligned with the slot 3010 on the panel 301, so that when the pressing mechanism 30 presses the grille 302, the buckle 3020 on the grille 302 can be accurately engaged with the slot 3010 on the panel 301.

[0057] Furthermore, refer to Fig.12 and Fig.13 The vertical telescopic module 210 includes a second telescopic drive member 2101 and a pressure plate 2102.

In a specific implementation, the second telescopic drive member 2101 adopts a telescopic cylinder, and the pressure plate 2102 is a short plate. The pressure plate 2102 is fixedly connected to the end of the telescopic shaft of the telescopic cylinder. The main part of the telescopic cylinder can be fixed on the downward side of the assembly platform 11, or an opening is designed on the assembly platform 11 to install the main part of the telescopic cylinder. When actually performing assembly, the telescopic cylinder drives the pressure plate 2102 to telescopically move vertically from top to bottom toward the corresponding position on the surface of the grille 302, so that the pressure plate 2102 The specific pressing point can be adjusted by adjusting the position of the telescopic cylinder in the horizontal direction of the assembly table 11.

The panel holding mechanism 22 can firmly fix the panel 301 on the assembly line 200 in the assembly area by pressing the panel 301, so that the panel 301 is in a fixed state at the correct assembly point on the assembly line 200 in the assembly area, so that when the pressing mechanism 30 presses the grille 302, the buckle 3020 on the grille 302 can be accurately engaged with the slot 3010 on the panel 301.

[0060] Further, refer to Figure 6 , Figure 7 , Fig.16 , Fig.17 The panel holding mechanism 22 includes a first telescopic pressing module 220 and a second telescopic pressing module 221, wherein the first telescopic pressing module 220 and the second telescopic pressing module 221 are arranged at intervals on the downward side of the assembly platform 11, wherein the first telescopic pressing module 220 and the second telescopic pressing module 221 are used to perform telescopic pressing toward the opposite side edges of the panel 301 at an angle to fix the panel 301 on the assembly line 200 in the assembly area. In a specific implementation, the first telescopic pressing module 220 and the second telescopic pressing module 221 adopt the same structure, and the first telescopic pressing module 220 and the second telescopic pressing module 221 are fixed at intervals on the downward side of the assembly platform 11, and the distance between the two is determined according to the overall size of the panel grille sheet metal 300. Usually, the first telescopic pressing module 220 and the second telescopic pressing module 221 should maintain a certain distance from the opposite sides of the panel grille sheet metal 300 in the horizontal direction. When assembling the panel grille sheet metal 300, the first telescopic pressing module 220 and the second telescopic pressing module 221 are tilted toward each other at a certain angle to perform telescopic pressing toward the opposite side edges of the panel 301. The opposite sides of the panel 301 are pressed firmly on the assembly line 200 by the pressing force of the first telescopic pressing module 220 and the second telescopic pressing module 221, so that when the pressing module presses the grille 302, the buckle 3020 on the grille 302 and the slot 3010 on the panel 301 can maintain a good alignment state, and the assembly is more stable and reliable.

[0061] Furthermore, refer to Fig.18 and Fig.19The first telescopic pressing module 220 and the second telescopic pressing module 221 both include a fourth telescopic driving member 2201 and a first pressing member 2202, wherein the fourth telescopic driving member 2201 is fixedly arranged on the downward side of the assembly platform 11, and the first pressing member 2202 is connected to the fourth telescopic driving member 2201, wherein the fourth telescopic driving member 2201 is used to drive the first pressing member 2202 to telescopically move toward the opposite side edges of the panel 301, so that the first pressing member 2202 is pressed against the opposite side edges of the panel 301. In a specific implementation, the fourth telescopic driving member 2201 adopts a telescopic cylinder. The two telescopic cylinders are respectively fixed at a certain distance on the downward side of the assembly table 11. The two telescopic cylinders are arranged to be inclined toward each other. The two first pressing members 2202 are respectively fixed at the ends of the telescopic shafts of the two telescopic cylinders. The first pressing plate 2102 can be designed as a plate-like structure, which is mainly used to press the opposite sides of the panel 301. The two first pressing members 2202 are respectively driven by the two telescopic cylinders to extend and retract toward the opposite sides of the panel 301. The two first pressing members 2202 are pressed against the opposite sides of the panel 301, so that the panel 301 is pressed on the assembly line 200 in the assembly area. The telescopic cylinders are provided with position sensors, which can detect whether the telescopic shaft is extended and retracted into place, thereby pressing the panel 301 into place.

[0062] Specifically, the first pressing member 2202 includes a fixed groove 2203 and a pressing roller 2204, wherein the fixed groove 2203 is connected to the fourth telescopic driving member 2201, and a plurality of pressing rollers 2204 are arranged and rolled in the fixed groove 2203 in the same direction. A plurality of pressing rollers 2204 are installed in the fixed groove 2203, and the pressing rollers 2204 can roll freely in the fixed groove 2203. The fixed groove 2203 is fixedly connected to the end of the telescopic shaft of the telescopic cylinder, and the telescopic cylinder drives the fixed groove 2203 to telescope and press toward the panel 301, and the pressing rollers 2204 contact the panel 301. Since the pressing rollers 2204 can roll freely, the panel 301 can be effectively prevented from being dislocated when pressing. The pressing rollers 2204 can be designed with a material with a certain elasticity, such as a flexible polyurethane material, so that the panel 301 can be prevented from being damaged and affecting the appearance of the product when pressing.

[0063] In one implementation, referring to Figure 6The positioning mechanism 20 includes a clamping and fixing mechanism 23, which is arranged on the assembly platform 11 and located in the assembly area, wherein the clamping and fixing mechanism 23 is used to clamp the two opposite sides of the panel 301 in the horizontal direction to limit the position deviation of the panel 301. In a specific implementation, when the pressing mechanism 30 presses the grille 302 toward the panel 301 during assembly, the panel 301 may be deflected by the grille 302, thereby causing the buckle 3020 on the grille 302 to fail to accurately align with the slot 3010 on the panel 301. By clamping the two opposite sides of the panel 301 by the clamping mechanism, the position of the panel 301 can be kept stable in the assembly area, and even if it is pressed by the grille 302, it can be kept at the correct assembly point, effectively preventing the position of the panel 301 from being deflected when the pressing mechanism 30 presses the grille 302 toward the panel 301, thereby improving the reliability of the assembly of the grille 302 and the panel 301.

[0064] Further, refer to Figure 7 , Fig.16 , Fig.17 as well as Figure 20 to Figure 23The first mounting portion 110 and the second mounting portion 111 are arranged at intervals on the downward side of the assembly platform 11, and the assembly area is arranged between the first mounting portion 110 and the second mounting portion 111. The clamping and fixing mechanism 23 includes a first telescopic clamping module 230 and a second telescopic clamping module 231, and the first telescopic clamping module 230 and the second telescopic clamping module 231 are respectively fixed to the first mounting portion 110 and the second mounting portion 111, wherein the first telescopic clamping module 230 and the second telescopic clamping module 231 are used to telescopically move toward the two opposite sides of the panel 301 in the horizontal direction in the horizontal direction to clamp the panel 301. In a specific implementation, the first mounting portion 110 and the second mounting portion 111 are fixed to the downward side of the assembly platform 11 at intervals, and the two are spaced apart by a certain distance and both extend a certain distance away from the downward side of the assembly platform 11. The first mounting portion 110 and the second mounting portion 111 are specifically two metal connectors, which can be designed by die casting. Various connecting screw holes are provided on the first mounting part 110 and the second mounting part 111, which are mainly used to install and fix the module components of the clamping and fixing mechanism 23. The assembly area is mainly in the range area between the first mounting part 110 and the second mounting part 111, and the assembly line 200 is arranged in the lower area between the first mounting part 110 and the second mounting part 111, and the panel grille sheet metal 300 can be transported between the first mounting part 110 and the second mounting part 111. The first telescopic clamping module 230 is installed on the first mounting part 110, and the second telescopic clamping module 231 is installed on the second mounting part 111. The two modules can be telescopically moved toward each other. During assembly, the first telescopic clamping module 230 and the second telescopic clamping module 231 are telescopically moved toward opposite sides of the panel 301 in the horizontal direction. Each module is pressed against one side of the panel 301 to clamp the panel 301 in the assembly area. The two telescopic clamping modules can both be in the form of telescopic cylinders. The main parts of the two telescopic cylinders are respectively installed on the first mounting part 110 and the second mounting part 111. After the two telescopic cylinders are extended and retracted, the telescopic shafts are driven to extend and press against the opposite sides of the panel 301 to clamp the panel 301. Position sensors are provided on the telescopic cylinders to detect whether the telescopic shafts are extended and retracted into place, thereby pressing and clamping the panel 301 into place. After the panel 301 is clamped, when the pressing mechanism 30 presses the grille 302 toward the panel 301, the position where the panel 301 is pressed by the grille 302 will not be offset and will still be in the correct assembly position. The buckle 3020 on the grille 302 is precisely aligned with the slot 3010 on the panel 301, which effectively improves the reliability of the assembly of the grille 302 and the panel 301.

[0065] In one embodiment, referring to Figure 24 to Figure 26The air conditioner outdoor unit panel grille automatic assembly device 100 also includes a first guide mechanism 40 and a second guide mechanism 50, wherein the first guide mechanism 40 is installed on the frame 10 and is located on opposite sides of the assembly line 200, and the second guide mechanism 50 is installed on the frame 10 and is located above the assembly line 200, wherein the first guide mechanism 40 is used to contact the opposite sides of the panel grille sheet metal 300 transported by the assembly line 200 in the horizontal direction to adjust the position of the panel grille sheet metal 300 in the horizontal direction, and the second guide mechanism 50 is used to contact the top of the panel grille sheet metal 300 transported by the assembly line 200 to adjust the position of the panel grille sheet metal 300 in the vertical direction.

The two guide plates remain parallel to the transportation direction of the assembly line 200, and the spacing can be designed according to the actual size of the panel grille sheet metal 300. The ends of the two guide plates that meet the panel grille sheet metal 300 are bent outward. In the process of the assembly line 200 transporting the panel grille sheet metal 300 toward the assembly area, the panel grille sheet metal 300 contacts the guide plates on the opposite sides of the transportation direction of the assembly line 200. The panel grille sheet metal 300 is passively moved with the movement of the assembly line 200, and its position in the horizontal direction is corrected by the guide plate, so that the panel grille sheet metal 300 is transported to the correct assembly point in the assembly area in a standard assembly form, which is convenient for the subsequent assembly operations of the positioning mechanism 20 and the pressing mechanism 30.
