[0051] Referring to Figures 9 to 11 In actual work process, when the turnover seat 402 is turned over by 90°: if the part insertion slot 4021 is horizontally oriented to the second push rod 403, the corresponding action is to push the L-foot part 600 on the first adapter table 401 into the part insertion slot 4021 of the turnover seat 402 by the second push rod 403; if the part insertion slot 4021 is upward, the corresponding action is to position the L-foot part 600 and paste the waterproof pad 700, and then insert the third push rod 404 into the push rod through hole 4022 and push the L-foot part 600 with the waterproof pad 700 out of the part insertion slot 4021, so that the L-foot part 600 falls into the second adapter table 405;

The first belt conveyor 201 and the second belt conveyor 501 can be conveniently connected to the existing production line to realize the transformation of the production line and reduce the cost of the manufacturer. Through the automatic and standardized work process, the application can stabilize product quality, eliminate manual operation differences, reduce the probability of subsequent installation failure of photovoltaic supports, and improve the overall system reliability.

[0055] The following shows a specific embodiment of the application.

[0056] Referring to Figures 7 to 12 , the part overturning device 400 of the application is shown:

[0057] The above part overturning device 400 further includes a first positioner 407 arranged above the overturning seat 402, which is used to detect the position of the L-foot part 600 on the overturning seat 402 and send the position information to the laminating device 300, so that the laminating device 300 can position the specific position of the L-foot part 600 after sucking the waterproof pad 700, improving the lamination accuracy. Thus, the assembly accuracy can be guaranteed, the lamination position of the L-foot part 600 and the waterproof pad 700 can be accurately controlled, and the waterproof sealing failure can be avoided. Specifically, the first positioner 407 can adopt a visual detection device such as a CCD camera, which captures real-time images of the L-foot part 600 on the overturning seat 402 through high-definition imaging technology, and analyzes the position coordinates of key feature points such as part edges and mounting holes 601 using image processing algorithms to form position information of the L-foot part 600.

[0058] Further, in order to facilitate the second push rod 403 to push the L-foot part 600 on the first adapter table 401 into the part slot 4021 of the turnover seat 402, a guide surface 4023 is arranged at the opening of the part slot 4021 on the end surface of the turnover seat 402, so that the entrance of the part slot 4021 presents an approximately trumpet-shaped expanding shape, and the L-foot part 600 is more easily inserted into the part slot 4021; at the same time, the height of the part slot 4021 is greater than the thickness of the L-foot part 600.

[0059] Secondly, the part turnover device 400 further comprises a mounting seat 408 and a position limiter 409; the turnover seat 402 is arranged between the end of the first adapter table 401 and the mounting seat 408, and the position limiter 409 is horizontally adjustably mounted on the mounting seat 408, and is arranged at the same height as the shorter end of the L-foot part 600 after being turned over, and the L-foot part 600 is attracted to the inner wall of the part slot 4021 by magnetic attraction. When the height of the part slot 4021 is greater than the thickness of the L-foot part 600, if the second push rod 403 pushes the L-foot part 600 into the part slot 4021 and the turnover seat 402 is turned over by 90°, the L-foot part 600 may slide or deflect, at this time, the L-foot part 600 is attracted to the inner wall of the part slot 4021 by the magnetic attraction of the position limiter 409, so as to realize "alignment", facilitate the first position limiter 407 to position the horizontal position of the L-foot part 600 without the need to reposition / calculate the deflection angle of the L-foot part 600, and ensure that the L-foot part 600 maintains a stable posture on the turnover seat 402, thereby ensuring the positioning accuracy when the waterproof pad is attached by the subsequent patching device 300. In addition, in actual application, the horizontal adjustability of the position limiter 409 enables the equipment to adapt to L-foot parts 600 of different size specifications, thereby enhancing the versatility and flexibility of the equipment. The application of the magnetic attraction mode not only ensures the close attachment of the L-foot part 600 to the inner wall of the part slot 4021, but also avoids possible damage to the part caused by mechanical clamping, thereby improving the overall assembly quality. Specifically, the position limiter 409 can adopt an electromagnet structure, by adjusting the magnetic force of the electromagnet, the adsorption force can be ensured while avoiding excessive extrusion of the L-foot part 600. In actual installation, the position limiter 409 is mounted on the mounting seat 408 through a threaded connection or a sliding rail mechanism, and the operator can quickly adjust the horizontal position of the position limiter 409 according to the thickness specifications or production requirements of the L-foot part 600, so that the end thereof maintains a gap of 2-5 mm with the surface of the L-foot part 600 after being turned over, which can realize magnetic attraction positioning without interfering with the part transportation.

[0060] The turnover seat 402 and the third push rod 404 are mounted on the same base 410, the base 410 is provided with a rotating shaft 4101 for driving the turnover seat 402, and the rotating shaft 4101 can be driven by a motor in the base 410; the rotating shaft 4101 and the third push rod 404 are arranged in parallel.

[0061] Referring to Figure 4 , the gasket conveying device 100 of the present application is shown:

[0062] The gasket conveying device 100 comprises a mounting table 101, a damping reel 102, a stripping block 103, a third belt conveyor 104, a compression roller 105 and a second stepper controller 106; the damping reel 102 is arranged at one end of the side of the mounting table 101 and is used to wind the release paper 800, the back adhesive surface of the waterproof gasket 700 is attached to the release paper 800, a certain gap is reserved between adjacent waterproof gaskets 700 to avoid complete attachment, then the patching device 300 can vacuum suck the non-adhesive surface of the waterproof gasket 700 and directly attach the waterproof gasket 700 to the L-foot part 600 which has been turned over 90° during the up-and-down movement of the waterproof gasket 700; the stripping block 103 is arranged at the other end of the side of the mounting table 101; the third belt conveyor 104 is arranged on the side of the mounting table 101 and below the damping reel 102 and the stripping block 103, at least one compression roller 105 is tightly arranged above the belt of the third belt conveyor 104, and the compression roller 105 is rotatably mounted on the side of the mounting table 101; the second stepper controller 106 is arranged between the damping reel 102 and the stripping block 103 and is used to detect the gap between the waterproof gaskets 700 and control the third belt conveyor 104; the release paper 800 on the damping reel 102 passes above the second stepper controller 106 and the stripping block 103 in turn and is rewound between the compression roller 105 and the third belt conveyor 104. Thus, the gasket conveying device 100 can convey the waterproof gaskets 700 one by one, and when the waterproof gasket 700 above the stripping block 103 is sucked by the patching device 300, the release paper 800 can continue to advance and be rewound between the compression roller 105 and the third belt conveyor 104, so as to peel off the release paper 800 and the waterproof gasket 700.

[0063] Further, the gasket conveying device 100 further comprises a second positioner 107 arranged above the stripping block 103, the second positioner 107 is used to detect the position of the waterproof gasket 700 on the stripping block 103 and send the position information to the patching device 300, so that the patching device 300 can locate the position of the waterproof gasket 700 to achieve accurate suction. Specifically, like the first positioner 407, the second positioner 107 can also adopt a visual detection device such as a CCD camera.

[0064] Referring to Figure 5, shows the part conveying device 200 of the present application, and it can be seen that the L-foot parts 600 are all attached to the upper side of the first belt conveyor 201 at the longer end, and the shorter end is located at the rear side of the conveying direction, so that the longer end of the L-foot part 600 can be pushed into the part insertion slot 4021 by the second push rod 403 in the subsequent process, ensuring the normal operation of the automatic attachment process; and the L-foot parts 600 are arranged at equal intervals above the first belt conveyor 201, and this arrangement can be achieved by manual placement or mechanical arm placement.

[0065] Referring to Figure 6 , shows the patch device 300 of the present application:

[0066] The above-mentioned patch device 300 includes a mechanical arm 301 with a two-section horizontal swing function, and a vacuum chuck 302 arranged at the movable end of the mechanical arm 301.

[0067] Referring to Figure 13 , shows the blanking device 500 of the present application:

[0068] The above-mentioned blanking device 500 includes a limiting piece 502, a thickness detector 503 and a fifth push rod 504; the limiting piece 502 is swingingly or liftingly fitted above the second belt conveyor 501, for controllably preventing the advancement of the L-foot part 600; the thickness detector 503 is liftingly fitted above the second belt conveyor 501 and located at the side of the limiting piece 502, for detecting the thickness of the L-foot part 600 blocked by the limiting piece 502, specifically the thickness of the shorter end, for judging whether the L-foot part has been attached with a waterproof pad 700; the fifth push rod 504 is arranged at one side of the end of the second belt conveyor 501, and according to the detection result of the thickness detector 503, the L-foot part 600 is divided. Thus, when the L-foot part 600 is conveyed to the second belt conveyor 501, the blanking device 500 will perform "quality detection", specifically detecting whether the shorter end of the L-foot part 600 is attached with a waterproof pad 700, and then the qualified products and unqualified products are divided. Specifically, the limiting piece 502 and the thickness detector 503 can be driven to lift by devices such as air cylinders and hydraulic cylinders.

[0069] Further, the above-mentioned blanking device 500 further includes a diversion guide rail 505, which is arranged at the other side of the end of the second belt conveyor 501 and opposite to the fifth push rod 504. Thus, the products that need to be divided (such as unqualified products) can be pushed by the fifth push rod 504 to the diversion guide rail 505 for conveying to a different destination from the products that do not need to be divided (qualified products).

[0070] Meanwhile, in order to ensure that the L-shaped leg part 600 pushed out from the turnover seat 402 is longer one end adheres to the upper surface of the second belt conveyor 501, so as to facilitate the detection of the thickness of the shorter one end, the output end of the fourth push rod 406 is provided with an inclined push plate 4061, and the lower end of the inclined push plate 4061 is away from the fourth push rod 406. When the L-shaped leg part 600 is about to be completely pushed out of the turnover seat 402, the inclined push plate 4061 moves to the lower end of the L-shaped leg part 600 and abuts against the lower end of the L-shaped leg part 600 under the drive of the fourth push rod 406, so that the L-shaped leg part 600 generates a tendency of the upper end leaning backward; and after the L-shaped leg part 600 completely separates from the turnover seat 402 and is no longer limited in the front and back directions by the turnover seat 402, the upper end of the L-shaped leg part 600 will naturally lean backward, that is, the shorter one end of the L-shaped leg part 600 will lean backward until the longer one end adheres to the upper surface of the inclined push plate 4061 and is pushed onto the second belt conveyor 501.

[0071] In the embodiment, the first belt conveyor 201, the first adapter table 401, the second adapter table 405, the second belt conveyor 501 and the third belt conveyor 104 are parallel to each other in the length direction of each device, and the first belt conveyor 201, the first adapter table 401 and the second adapter table 405 are arranged adjacent to each other, and the second belt conveyor 501 and the second adapter table 405 are arranged along the same straight line, so that the space layout of the entire device is more compact and the floor area is smaller.

[0072] In the embodiment, the first step controller 202 and the second step controller 106 can be photoelectric sensors, which detect the gap between adjacent L-shaped leg parts 600 / waterproof pads 700 through photoelectric signals, so as to determine whether the corresponding device has conveyed an L-shaped leg part 600 / waterproof pad 700 forward, and then issue corresponding control instructions through a preset program logic, the control instructions are converted into current to drive the motor of the belt conveyor to work, and finally the motor is accurately controlled to rotate at a preset angle and speed, so that the corresponding device can convey the L-shaped leg part 600 / waterproof pad 700 in a step-by-step manner at a preset frequency and speed.

[0073] In the embodiment, the output end of each push rod (except the fourth push rod 406) can be provided with a push plate, so as to have a larger contact area with the part and ensure that the action of pushing the L-shaped leg part 600 to the corresponding position can be stably performed.

[0074] The working process of the application is as follows:

[0075] (I) accessory conveying action

[0076] The L-foot parts 600 are arranged on the first belt conveyor 201 at equal intervals in the posture of "longer end horizontally, shorter end vertically upward", and the step conveying of the first belt conveyor 201 is controlled by the first step controller 202; when the L-foot parts 600 reach the end of the first belt conveyor 201, the first push rod 203 pushes them into the first adapter table 401 one by one. In the initial state, the part slot 4021 of the turnover seat 402 is horizontally oriented to the second push rod 403, and the second push rod 403 pushes the L-foot parts 600 on the first adapter table 401 into the part slot 4021 of the turnover seat 402; then, the turnover seat 402 is turned over 90° under the drive of the rotating shaft 4101, so that the part slot 4021 is upward, and the L-foot parts 600 are turned over 90°, at this time, the shorter end of the L-foot parts 600 is turned to the horizontal state, and the surface of the pre-bonded waterproof pad 700 is upward; the positioner 409 ensures the posture stability by magnetically attracting the L-foot parts 600 to the inner wall of the part slot 4021; then, the first positioner 407 detects the position information of the L-foot parts 600 and sends it to the patch device 300.

[0077] At the same time, the damping tray 102 releases the release paper 800 with the waterproof pad 700, and the step conveying of the third belt conveyor 104 is controlled by the second step controller 106; each step of the third belt conveyor 104 drives each waterproof pad on the release paper 800 to move forward by one step; each step is detected by the second positioner 107 to send the specific position of the waterproof pad 700 above the stripping block 103 to the patch device 300.

[0078] (II) Bonding action

[0079] According to the respective position information of the waterproof pad 700 on the stripping block 103 and the L-foot parts 600 on the turnover seat 402, the mechanical arm 301 of the patch device 300 drives its vacuum chuck 302 to perform a combination of horizontal movement and lifting movement between the two position information, and the waterproof pad 700 is sucked and bonded to the L-foot parts 600, specifically, to the back of the shorter end of the L-foot parts 600 (the preset bonding surface).

[0080] (III) Quality detection

[0081] After the bonding is completed, the third push rod 404 is inserted into the push rod through hole 4022 of the turnover seat 402, and the bonded L-foot parts 600 are pushed out of the part slot 4021, so that they fall into the second adapter table 405; the fourth push rod 406 pushes the L-foot parts 600 on the second adapter table 405 into the second belt conveyor 501 through the inclined push plate 4061, at this time, the L-foot parts 600 restore the posture of "longer end horizontally, shorter end vertically upward", and are conveyed forward by the second belt conveyor 501; the limiting part 502 performs continuous circulation of "blocking" and "release" state:

[0082] In the blocking state, when the L-foot part 600 moves to the limiting piece 502, the limiting piece 502 prevents it from advancing, and then the thickness detector 503 is lowered and detects the thickness of the shorter end of the L-foot part 600 (judges whether the waterproof pad 700 is attached), and feeds back the detection result to the control system to determine the action of the fifth push rod 504; and then the limiting piece 502 switches to the "release" state;

[0083] Then, the second belt conveyor 501 continues to forwardly convey the L-foot part 600 until it moves to the end of the second belt conveyor 501, and the fifth push rod 504 divides the flow according to the detection result: the qualified products with the waterproof pad 700 attached are continuously conveyed by the second belt conveyor 501 to the subsequent process; and the unqualified products are pushed by the fifth push rod 504 to the shunt guide rail 505 and conveyed to the designated area.

[0084] In summary, the present application innovatively realizes the integrated automatic assembly and quality detection between the L-foot part 600 special for the metal roof photovoltaic support and the waterproof pad 700 with adhesive backing, and breakthroughly solves the efficiency bottleneck and quality fluctuation problem of traditional manual assembly, significantly improves the production efficiency and the automation level of the photovoltaic support supporting component industry. Specifically, the following technical effects can be achieved:

[0085] (1) Precise conveying control

[0086] The L-foot part 600 and the waterproof pad 700 are respectively conveyed synchronously by independent conveying devices equipped with stepping controllers, and the conveying speed can be precisely adjusted according to the assembly rhythm to ensure efficient matching of material supply and assembly process.

[0087] (2) Directional overturning and fixing

[0088] According to the structural characteristics of the L-foot part 600, a special part overturning device 400 is arranged to realize directional overturning, and a limiter 409 is arranged to realize precise fixing of the L-foot part 600 on the assembly station (overturning seat 402), thereby providing a stable reference for subsequent attachment.

[0089] (3) Automatic adsorption assembly

[0090] The patching device 300 is controlled by two positioners to realize precise positioning of the L-foot part 600 and the waterproof pad 700, and to control the vacuum chuck 302 of the patching device 300 to precisely suck the waterproof pad 700, and then to complete the automatic assembly of the waterproof pad 700 and the L-foot part 600 according to the positioning information, thereby ensuring the attachment position accuracy.

[0091] (4) Quality selection

[0092] The quality detection function is configured at the rear end of the assembling process. The thickness of the shorter end of the L-shaped foot part 600 is detected by the thickness detector 503 to automatically identify unqualified products and trigger the rejection mechanism, so as to remove the unqualified products from the production flow and realize the automatic closed loop of the whole process of "assembly-detection-screening".

[0093] The above embodiments and drawings are not limited to the product shape and style of the present application, and any appropriate changes or modifications made by those skilled in the art shall be considered as not departing from the scope of the patent of the present application.
