[0045] The end of the top cover conveying and positioning line 28 is provided with an electric cylinder mounting plate 21, where the end is the end relative to the transmission direction of the top cover 2.

[0046] An end aluminum profile 23 is also provided at the end of the top cover conveying and positioning line 28, and a front and back detection camera 22 is provided directly above the end aluminum profile 23; when the top cover 2 is transmitted to the end of the top cover conveying and positioning line 28, the second loading robot 20 will grab the top cover 2 and lift it. During the lifting process, the front and back detection camera 22 can shoot the lower end of the top cover 2 and transmit it to the control unit for identification. If the top cover 2 is placed upside down, the second loading robot 20 can flip it over and then place it on the top of the air conditioner outdoor unit.

[0047] The end of the top cover conveying and positioning line 28 is also provided with a positioning cylinder 26 and a positioning push plate 27, wherein the positioning push plate 27 is arranged opposite to the adjustment arm 30, and is used for when the top cover 2 is transmitted to the end of the top cover conveying and positioning line 28, the positioning cylinder 26 drives the positioning push plate 27 to extend, and pushes the top cover 2 to a position abutting against the adjustment arm 30. The reason why the present application is provided with the positioning push plate 27, the adjustment arm 30 and the end positioning blocking plate 35 is to convey the top cover 2 of a specific size and model to a fixed position, so as to facilitate the second loading robot 20 to clamp it at the fixed position.

[0048] A material blocking photoelectric detector 29 is also provided at the head end of the top cover conveying and positioning line 28. The material blocking photoelectric detector 29 is located on one side of the top cover conveying and positioning line 28.

The locking photoelectric detector 60 is located at the rear end of the assembly photoelectric detector 59 in the external machine transmission line 33, and the locking photoelectric detector 60 is located inside the assembly assembly 6. When the assembly photoelectric detector 59 detects the external machine, the external machine blocking mechanism 34 rises to block the external machine. At the same time, the second loading robot 20 places the clamped top cover 2 at the bottom of the external machine. After the placement is completed, the external machine blocking mechanism 34 descends so that the external machine equipped with the top cover 2 continues to move forward until the locking photoelectric detector 60 detects the external machine, and the external machine transmission line 33 stops transmission.

[0050] The external machine blocking mechanism 34 includes a blocking mechanism mounting frame 37, a blocking cylinder 36 and a blocking plate 35. The blocking mechanism mounting frame 37 is fixed below the external machine transmission line 33. The blocking cylinder 36 is connected to a foot 39 through a double earring 38.

The blocking plate 35 is a bent structure. The middle of the blocking plate 35 is rotatably connected to the top end of the blocking cylinder mounting frame 37. The top end of the blocking plate 35 is located in the middle of the external machine transmission line 33. When the blocking cylinder 36 extends, it pushes the bottom end of the blocking plate 35 so that the top end of the blocking plate 35 drops below the external machine transmission line 33; when the blocking cylinder 36 retracts, the bottom end of the blocking plate 35 is retracted so that the top end of the blocking plate 35 rises above the external machine transmission line 33.

[0051] After the top cover 2 is placed, the outdoor unit stops moving at the assembly component 6; the assembly component 6 includes a fastening unit and a pressing unit 46, the pressing unit 46 includes a downward pressing cylinder 56 and a downward pressing plate 57 connected thereto, the fastening unit includes a three-dimensional slide rail and a screw gun 52, the screw gun 52 is slidably connected in the three-dimensional slide rail, and is used to fasten the top cover 2 and the outdoor unit of the air conditioner. The downward pressing cylinder 56 drives the downward pressing plate 57 to press down, so that the top cover 2 is pressed against the top of the outdoor unit of the air conditioner; the screw gun 52 moves around the three-dimensional slide rail, embeds the screws into the top cover 2 and the outdoor unit of the air conditioner, and fastens the top cover 2 and the outdoor unit of the air conditioner.

[0052] The assembly component 6 also includes a screw mechanism bracket 40, and the three-dimensional slide rails include an X-axis slide rail 43, a Y-axis slide rail 44 and a Z-axis slide rail 45; there are two X-axis slide rails 43, which are arranged in parallel in the screw mechanism bracket 40, and the two ends of the Y-axis slide rail 44 are respectively slidably connected to the X-axis slide rail 43, and the Z-axis slide rail 45 is slidably connected to the Y-axis slide rail 44, and the screw gun 52 is fixed in the Z-axis slide rail 45.

[0053] The fastening unit further includes a lifting guide rod 51, a rotating cylinder 50 and a screw gun mounting frame 49. The screw gun 52 is located in the screw gun mounting frame 49. The screw gun mounting frame 49 is connected to the output end of the rotating cylinder 50. The rotating cylinder 50 is fixed to one end of the lifting guide rod 51. The other end of the lifting guide rod 51 is fixedly connected to the Z-axis slide rail 45. The rotating cylinder 50 drives the screw gun mounting frame 49 and the screw gun 52 to rotate, so as to tighten the screws in the top cover 2 and the external machine. The fastening unit is fixed in the Z-axis slide rail 45. The Z-axis slide rail 45 can move along the Y-axis slide rail 44. The Y-axis slide rail 44 can move along the X-axis slide rail 43. In addition to rotating, the screw gun 52 can also move along the Z-axis, Y-axis and Z-axis, so as to realize the screw fixing action at different positions.

[0054] The clamping unit 46 also includes a downward pressing cylinder connecting plate 55, a spring guide rod 54 and a downward pressing spring 53; downward pressing cylinder mounting plates 47 are respectively arranged at the corresponding positions of the two X axes, and the downward pressing cylinder 56 is fixedly connected to the downward pressing cylinder mounting plate 47, and the downward pressing cylinder 56 is fixed above the downward pressing cylinder connecting plate 55, the bottom end of the spring guide rod 54 is fixed in the downward pressing plate 57, and the top end of the spring guide rod 54 is slidably fixed in the downward pressing cylinder connecting plate 55, and the downward pressing spring 53 is nested outside the spring guide rod 54; the two ends of the downward pressing plate 57 are respectively connected to the downward pressing cylinder 56 on both sides through the spring guide rod 54. The downward pressing spring 53 and the spring guide rod 54 are used to provide a buffer force for the downward pressing plate 57 during the downward pressing process. The position of the downward pressing plate 57 corresponds exactly to the top position of the external machine when it stops moving.

[0055] The assembly component 6 also includes a first hole position recognition camera 42 and a second hole position recognition camera 48 respectively located on both sides of the lower pressing plate 57; the first hole position recognition camera 42 and the second hole position recognition camera 48 are connected to a control unit, and the control unit is connected to the fastening unit. When the lower pressing plate 57 presses the top cover 2 against the top of the external machine, the first hole position recognition camera 42 and the second hole position recognition camera 48 take photos to identify the hole positions on the top cover 2, and then calculate the spatial coordinates of the hole positions through a comparison program with the template photo. After the calculation is completed, the control unit controls the fastening unit to first complete the locking of one side of the top cover 2, and then move to the other side. During the movement, the rotating motor 50 is activated to rotate the screw gun mounting frame 49 and the screw gun 52 by 180° to complete the locking of the other side. After the top cover 2 is locked, the lower pressing cylinder 56 retracts, driving the lower pressing plate 57 to move upward, and then the external machine transmission line 33 transports the external machine after the top cover 2 is assembled and locked to the next position, and this cycle is repeated.

[0056] The present application also provides an automatic assembly method for the top cover 2 of the air-conditioning outdoor unit, which is as follows: before starting the machine, the material cart 1 is manually filled with the top cover 2. After the loading is completed, the employee selects the corresponding program in the control center according to the machine model. After the selection is completed, the adjusting arm 30 moves to the corresponding position driven by the electric cylinder 32 and stops, and then the equipment is started. The first loading robot 13 drives the suction cup 8 to move to the material cart 1 to suck up a top cover 2. After the sucking is completed, the top cover 2 is driven by the first loading robot 13 to move to the top cover conveying positioning line 28, and then the top cover 2 is placed on the top cover conveying positioning line 28. If the blocking photoelectric detector 29 detects that there is a top cover 2 on the top cover conveying positioning line 28 at this time, the first loading robot 13 will wait for discharge above the top cover conveying positioning line 28; after the discharge is completed, the first loading robot 13 will once again go to the material cart 1 to suck up the top cover 2. At this time, the top cover 2 is transported to the end aluminum profile 23 and the end positioning blocking plate 35 along the top cover conveying positioning line 28. When the in-place photoelectric detector 25 detects After reaching the top cover 2, the top cover conveying positioning line 28 stops conveying, and then the positioning cylinder 26 extends to position the top cover 2 between the positioning push plate 27 and the adjusting arm 30. After positioning is completed, the positioning cylinder 26 retracts, and the second feeding robot 20 moves to the top cover 2 after positioning is completed, and then the clamping cylinder 16 retracts to clamp the top cover 2 between the movable clamping plate 15 and the fixed clamping plate 19. After the top cover 2 is clamped, the second feeding robot 20 moves to the top of the front and back detection camera 22, and then stops and waits for the front and back detection camera 22 to complete the front and back detection of the top cover 2; the reason for detecting the front and back of the top cover 2 here is that the top cover 2 is not necessarily placed in the same direction when it is manually placed in the material car 1. Once the direction of the top cover 2 is wrong, the top cover 2 cannot be assembled on the air conditioner outdoor unit. The principle of using the front and back detection camera 22 to detect the front and back of the top cover 2 is that one side of the top cover 2 is affixed with a black sponge, and the other side is not affixed, and then the front and back of the top cover 2 is judged by comparing the template photo after taking a photo with the front and back detection camera 22.

[0057] After the positive and negative detection is completed, the control unit sends the detection result data to the second loading robot 20; if it is detected that the direction of the top cover 2 is reversed, the second loading robot 20 will adjust the direction of the top cover 2 to be assembled on the external unit by rotating the six axes. Then the second loading robot 20 drives the top cover 2 to move above the air conditioner external unit at the external unit transmission line 33. When the assembly photoelectric detector 59 detects that the external unit is in place, the second loading robot 20 assembles the top cover 2 to the external unit. After the assembly is completed, the blocking cylinder 36 extends out, driving the blocking plate 35 to fall, and then the external unit transmission line 33 transports the external unit to the bottom of the assembly component 6. When the locking photoelectric detector 60 detects the external unit, the external unit transmission line 33 stops running. After being transported to the position, the downward pressing cylinder 56 extends out, driving the lower pressing plate 57 to move downward to press the top cover 2; the reason for pressing the top cover 2 here is that when the second loading robot 20 assembles the top cover 2 to the external unit, the top cover 2 is not fully assembled in place, so when the top cover 2 is screwed and locked, a downward force is required to fully assemble the top cover 2 in place.

[0058] After being pressed into place, the first hole position recognition camera 42 and the second hole position recognition camera 48 will take photos to identify the holes on the top cover 2, and then calculate the spatial coordinates of the holes through a comparison program with the template photo. After the calculation is completed, the control center controls the screws to first complete the locking of one side of the top cover 2, and then move to the other side.
