[0026] like Figures 1 to 8As shown, a skylight sealing strip installation device includes a frame 13, a robotic arm 14, a pressing tool assembly and a sliding carrier 21. The robotic arm 14 is fixedly installed on the frame 13, and also includes a protective fence 11. The protective fence 11 encloses an operating space. The frame 13, the robotic arm 14 and the pressing tool assembly are arranged in the operating space. The frame 13 and the protective fence 11 are relatively fixedly arranged, or the frame 13 is directly fixedly installed on the protective fence 11; a grating 12 is set in the open area of ​​the protective fence 11, and the grating 12 is set along the direction of the protective fence 11 to prevent someone from accidentally entering the operating space during operation and causing injury, thereby ensuring personal safety.

[0027] The sliding carrier 21 carries the skylight frame on which the sealing strip is to be installed. Specifically, a plurality of skylight positioning columns 22 are fixedly arranged on the upper side of the sliding carrier 21, which are arranged according to the shape of the skylight frame to be installed and are used to position the skylight frame; the pressing tooling assembly is connected to the end of the robotic arm 14 and is driven by the robotic arm 14 to be placed above the skylight frame to bond the sealing strip to the upper side of the skylight frame.

[0028] The pressing tooling assembly includes a mounting plate 51, and a sealing strip tooling 52 is fixedly connected to the bottom of the mounting plate 51. The sealing strip tooling 52 is provided with a card slot 53 on the side facing the skylight frame. The shape and position of the card slot 53 correspond to the area of ​​the skylight frame where the sealing strip is to be installed. An X-direction limit column 61 and a Y-direction limit column 62 are provided on the outside of the sealing strip tooling 52. The X-direction limit column 61 and the Y-direction limit column 62 are fixedly connected to the mounting plate 51 and abut against the outer edge of the skylight frame, respectively used to limit the relative movement of the sealing strip tooling 52 relative to the skylight frame in the X direction and the Y direction; a floating compensation mechanism is provided between the end of the robotic arm 14 and the mounting plate 51, and the floating compensation mechanism is used to make the mounting plate 51 move relative to the end of the robotic arm 14 in the X direction and the Y direction.

[0029] During installation, the skylight frame is placed on the sliding carrier 21 and is accurately positioned by the skylight positioning column 22; the operator clamps the sealing strip to be installed in the slot 53, and the robotic arm 14 drives the pressing tooling assembly to move above the skylight frame and drives the sealing strip tooling 52 to fall; during the falling process, the X-axis limit column 61 and the Y-axis limit column 62 are respectively clamped on the outer edges of the skylight frame in different directions, so that the sealing strip tooling 52 and the skylight frame are accurately positioned relative to each other, and then the robotic arm 14 drives the sealing strip tooling 52 to continue to fall until the sealing strip in the slot 53 is tightly adhered to the skylight frame, and then drives the sealing strip tooling 52 to rise, so that the slot 53 is separated from the sealing strip, and the pressing tooling assembly is reset, waiting for the next installation.

[0030] Preferably, a detection device 54 is provided at the slot 53 to detect whether a sealing strip is installed. The subsequent operation will be performed only when the detection device 54 detects that a sealing strip is present in the slot 53. The detection device 54 can be a contact switch, a laser sensor, or other device capable of achieving the above functions.

[0031] Specifically, if Figure 7 and Figure 8 As shown, the floating compensation mechanism includes a Y-direction mounting rod 71, a Y-direction floating spring 72, a Y-direction floating block 74, a Y-direction floating plate 75, an X-direction mounting rod 81, an X-direction floating spring 83, an X-direction floating block 84 and an X-direction floating plate 85. The Y-direction mounting rod 71 is fixedly mounted on the mounting plate 51 along the Y direction through the Y-direction fixed block 73. Two Y-direction floating blocks 74 are slidably mounted on each Y-direction mounting rod 71. The Y-direction floating blocks 74 and the Y-direction fixed blocks 73 adjacent to them respectively abut against each other. Connected to the Y-direction floating spring 72, the Y-direction floating plate 75 is fixedly mounted on the Y-direction floating block 74. The X-direction mounting rod 81 is fixedly mounted on the Y-direction floating plate 75 via the X-direction fixed block 82. Two X-direction floating blocks 84 are slidably mounted on each X-direction mounting rod 81. The X-direction floating blocks 84 abut against the adjacent X-direction fixed block 82 in each case. The X-direction floating plate 85 is fixedly mounted on the X-direction floating blocks 84. The end of the robotic arm 14 is connected to the X-direction floating plate 85. This floating compensation mechanism allows for fine adjustments in the relative position between the end of the robotic arm 14 and the skylight frame during the sealing strip installation process, compensating for minor errors due to manufacturing tolerances, placement, and other factors.

[0032] A force sensor 86 is connected between the end of the robotic arm 14 and the mounting plate 51. The force sensor 86 is used to detect the Z-direction force applied to the end of the robotic arm 14. By detecting the force applied to the robotic arm 14 in real time, the pressing force of the robotic arm 14 on the sealing strip is continuously monitored, and it is determined whether the sealing strip has completed the bonding process.

[0033] In order to prevent the sealing strip from being difficult to separate from the card slot 53 due to excessive friction and other reasons after the bonding is completed, causing the sealing strip to be pulled up from the skylight frame again, a clamping column 91 is set on the mounting plate 51 along the Z direction. The clamping column 91 is driven by a clamping cylinder 92 and moves back and forth along the Z direction relative to the mounting plate 51. When the clamping column 91 is in a high position, it is above the card slot 53. There are multiple clamping columns 91, and they are distributed within each edge line and corner of the card slot 53. Through the above structure, when the sealing strip tooling 52 moves upward, the clamping cylinder 92 drives the clamping column 91 to pass through the card slot 53 and abut against the sealing strip, ensuring that the sealing strip can be smoothly separated from the card slot 53 and ensuring the bonding effect of the sealing strip.

[0034] Preferably, the sliding carrier 21 moves along the Y direction relative to the frame 13, so that after the skylight frame on one sliding carrier 21 is installed with the sealing strip, it can be removed and the next sliding carrier 21 can continue to move to this position, thereby improving the installation efficiency.

[0035] like Figure 4 and Figure 5 As shown, a position detection sensor 23 is provided on the sliding carrier 21; it also includes a positioning clamping mechanism, which includes a positioning fixing frame 31, a blocking cylinder 32 and a clamping cylinder 34. The positioning fixing frame 31 is fixed relative to the frame 13, and the blocking cylinder 32 and the clamping cylinder 34 are fixedly installed on the positioning fixing frame 31. A positioning point is set on the positioning fixing frame 31. The position detection sensor 23 moves with the sliding carrier 21 until the positioning point is detected, indicating that the sliding carrier has moved to the predetermined position and stopped moving. The action end of the blocking cylinder 32 is connected The blocking rod 33 is arranged along the X direction. When the blocking cylinder 32 is in the extended position, the blocking rod 33 abuts the edge of the sliding carrier 21. When the blocking cylinder 32 is in the retracted position, the blocking rod 33 does not interfere with the movement of the sliding carrier 21. The action end of the clamping cylinder 34 is connected to the clamping rotating rod 35. The clamping cylinder 34 can be a swinging cylinder. When the clamping cylinder 34 is in the extended position, the clamping rotating rod 35 rotates a certain angle and abuts the edge of the side of the sliding carrier 21 away from the blocking rod 33. When the clamping cylinder 34 is in the retracted position, the clamping rotating rod 35 is disengaged from the sliding carrier 21. Through the above structure, when the sliding carrier 21 moves to the predetermined position, the position detection sensor 23 sends a signal and stops the sliding carrier 21 from moving. The blocking cylinder 32 and the clamping cylinder 34 both move to the extended position, so that the blocking rod 33 and the clamping rotating rod 35 abut against the edges of both sides of the sliding carrier 21, completing mechanical positioning and clamping to prevent the sliding carrier 21 from slipping.

[0036] like Figure 6 As shown, the sliding carrier 21 is a cantilever structure, and the end of the sliding carrier 21 close to the frame 13 is fixedly connected to the frame 13; it also includes a lifting support mechanism, and the lifting support mechanism includes a support frame 41, a lifting cylinder 42 and a support rod 43. The support frame 41 is fixedly arranged relative to the frame 13, and the lifting cylinder 42 is fixedly installed on the support frame 41 along the Z direction. The action end of the lifting cylinder 42 is connected to the support rod 43. When the lifting cylinder 42 is in the extended position, the support rod 43 rises and abuts against the bottom surface of the end of the sliding carrier 21 away from the frame 13 to support the free end of the sliding carrier 21 to ensure the structural strength and the accuracy of the installation position.
