[0027] See also Figures 1 to 5 The present application provides a reverse engineering scanning device, which is arranged at the bottom of a photovoltaic panel water guide groove, and includes: a first shell 100, a second shell 200, a support assembly 300 and a scanning assembly 400. The second shell 200 is arranged in the first shell 100 and is fixedly connected to the first shell 100. A buffer zone 110 is formed between the inner wall of the first shell 100 and the outer wall of the second shell 200. The support assembly 300 passes through the side wall of the first shell 100 and extends into the buffer zone 110, and the support assembly 300 can slide into the second shell 200 along the extending direction. The support assembly 300 is used to fix the sample. The scanning assembly 400 is slidably connected to the inner wall of the second shell 200.

[0028] Specifically, four support assemblies 300 are provided, which are respectively distributed on four opposite side walls of the first shell 100, one end of the support assembly 300 passes through the side wall of the first shell 100 and enters the buffer zone 110, and the other end of the support assembly 300 is outside the first shell 100, and the support assembly 300 can pass through the corresponding side wall of the second shell 200 in the direction of extending into the first shell 100 by pushing or pulling, and enter the interior of the second shell 200, and the two opposite support assemblies 300 clamp the sample inside the second shell 200, and the two sides of the first shell 100 where the support assemblies 300 are not provided are fixedly connected to the corresponding two sides of the second shell 200, and can be opened outward to facilitate the placement of the sample, and four scanning assemblies 400 are provided, two of which can move up and down along the inner walls of the two sides of the second shell 200 that can be opened, and the other two scanning assemblies 400 Slide along the inner wall of the second shell 200 on which the support assembly 300 is provided. When scanning is required, the first shell 100 and the second shell 200 are opened, and the two opposing support assemblies 300 are pushed inward so that they extend from the buffer zone 110 through the second shell 200 into the second shell 200, and the sample is clamped in the second shell 200. The first shell 100 and the second shell 200 are closed, and the scanning assembly 400 starts to slide to scan the sample. When the scanning assembly 400 is blocked by the support assembly 300, the other support assemblies 300 are extended from the buffer zone 110 into the second shell 200 and clamp the sample. The two support assemblies 300 that first clamp the sample are retracted from the second shell 200 into the buffer zone 110, and the scanning assembly 400 performs a second scan. After the scan is completed, the support assembly 300 is retracted into the buffer zone 110, and the sample is taken out, thereby completing the scan.

[0029] The present application provides a technical solution adopted by a reverse engineering scanning device that can achieve the following beneficial effects: by setting the first shell 100 and the second shell 200, one end of the support component 300 is received in the buffer zone 110, and by the cooperation of multiple support components 300, the problem that part of the sample cannot be scanned due to support during scanning is solved, thereby avoiding the phenomenon of incomplete scanning parameters; at the same time, by clamping the two relative support components 300 and cooperating with multiple support components 300, the problem that the scanning parameter error caused by the change of the rotation angle of the sample during scanning is solved; by slidingly connecting the scanning component 400 with the inner wall of the second shell 200 and cooperating with the setting of the buffer zone 110, the problem that the support component 300 blocks the sliding of the scanning component 400 during scanning is solved; at the same time, by performing a local secondary scanning of the sample, the scanning parameters are compared and verified with each other, thereby improving the accuracy of the scanning.

[0030] In a preferred embodiment, the support assembly 300 includes at least two first support rods 310 , and the two first support rods 310 respectively penetrate two opposite sides of the first shell 100 in a horizontal direction and can extend into the second shell 200 in a horizontal direction.

[0031] Specifically, the first support rod 310 can be a screw, a hydraulic jack, a cylinder, etc., and a pressure sensor can also be arranged on the first support assembly 300. The clamping force is determined by the value of the pressure sensor. Different support types are selected according to the type and material of the sample. The two first support rods 310 are symmetrically and horizontally arranged on the east and west side walls of the first shell 100, respectively. The two first support rods 310 extend into one end of the buffer zone 110. When it is necessary to clamp the sample, they both slowly extend into the second shell 200 from the buffer zone 110 and clamp the sample. When the first support rod 310 is not needed to clamp the sample, the end of the first support rod 310 extending into the second shell 200 is slowly retracted from the second shell 200 into the buffer zone 110, so that the inner wall of the second shell 200 is always in an unobstructed state, thereby ensuring the smooth sliding of the scanning assembly 400 and solving the problem that the first support rod 310 hinders the sliding of the scanning assembly 400, resulting in the inability to scan part of the sample.

[0032] In the optimized solution, in order to consider the convenience of support, the support assembly 300 includes at least two second support rods 320, and the two first support rods 310 vertically penetrate the opposite sides of the first shell 100 respectively, and can extend into the second shell 200 along the vertical direction.

[0033] Specifically, the second support rod 320 can also be a screw, a hydraulic jack, a cylinder, etc., and a pressure sensor can also be set on the first support component 300. The clamping force is determined by the value of the pressure sensor. Different support types are selected according to the type and material of the sample. The two second support rods 320 are symmetrically and vertically arranged on the upper and lower side walls of the first shell 100, and the two second support rods 320 extend into one end of the buffer zone 110. After the scanning component 400 completes the first scan, the first support rod 310 still clamps the sample, and the second support rods 320 slowly extend from the buffer zone 110 into the second shell 200 and clamp the sample. After the second support rod 320 clamps the sample, the first support rod 310 extends into the second shell One end of the body 200 is slowly retracted from the second shell 200 into the buffer zone 110, and the scanning component 400 performs a second scan. When the scanning component 400 completes the scanning, the first shell 100 and the second shell 200 are opened, and the sample is held by a device for collecting the sample or by hand. Then, the second support rod 320 clamps one end of the sample and slowly retracts it from the second shell 200 into the buffer zone 110 to complete the scanning of the sample. Through the mutual cooperation of the first support rod 310 and the second support rod 320, the problem that part of the sample cannot be scanned due to support during scanning is solved, thereby avoiding the phenomenon of incomplete scanning parameters. At the same time, the scanning component 400 scans twice to obtain two scanning parameters, and calibrates and compares the two parameters to improve the accuracy of the scanning.

[0034] In a better embodiment, in order to improve scanning efficiency, the scanning assembly 400 includes at least two first scanning rods 410 , and the first scanning rods 410 are slidably connected to the inner wall of the second shell 200 .

[0035] Two first scanning rods 410 are provided, which are respectively provided on the east and west side walls of the second shell 200. The first scanning rods 410 slide along the east, west, upper and lower side walls of the second shell 200. When the first support rod 310 extends from the east and west side walls of the second shell 200, the two first scanning rods 410 respectively move from the first support assembly 300 extending from the east and west side walls of the second shell 200 to the first support assembly 300 extending from the west and east side walls of the second shell 200 and perform scanning. After the two second support assemblies 300 respectively extend from the upper and lower side walls of the second shell 200 and clamp the sample, the first support rod 310 retracts. Returning to the buffer zone 110, the two first scanning rods 410 first slide from the position where the first support rod 310 extends into the second shell 200 to the upper and lower second support rods 320 respectively, and then the two first scanning rods 410 respectively move from the second support assembly 300 extending from the upper and lower side walls of the second shell 200 to the second support assembly 300 extending from the lower and upper side walls of the second shell 200, and scan, thereby completing the scanning of the four sides of the sample and solving the problem of obstruction between the first support rod 310 and the second support rod 320, making scanning simpler and more convenient, and setting two first scanning rods 410 to scan from both sides at the same time to improve scanning efficiency.

[0036] In a further embodiment, in order to consider the continuity of scanning, a first rangefinder 411 and a plurality of first cameras 413 are provided on the first scanning rod 410. The first rangefinder 411 is provided at both ends of the first scanning rod 410 for detecting the distance between the first scanning rod 410 and the inner wall of the second shell 200. The first camera 413 is provided on the side of the first scanning rod 410 close to the sample for scanning the parameters of the sample.

[0037] Specifically, the first camera 413 can use a rangefinder camera in the prior art, and the first cameras 413 are equidistantly distributed on the first scanning rod 410. At the same time, four first rangefinders 411 are arranged at both ends of the first scanning rod 410, and the first rangefinders 411 are respectively arranged on the upper, lower, east and west sides of one end of the first scanning rod 410. When the first scanning rod 410 slides in the second shell 200, the first rangefinder 411 continuously detects the distance from the first scanning rod 410 to other side walls of the second shell 200. For example, when the first scanning rod 410 slides from top to bottom on the east side wall of the second shell 200, When the first rangefinder 411 detects that the distance from the first scanning rod 410 to the lower side wall of the second shell 200 reaches a threshold, the scanning rod changes its sliding direction from sliding up and down on the east side wall of the second shell 200 to moving east-west on the lower side wall of the second shell 200. By setting four first rangefinders 411, the distance between the first scanning rod 410 and the side wall of the second shell 200 is detected respectively, thereby changing its scanning direction, making the scanning process simpler and more convenient, and the scanning is smoother, reducing the time of manually opening the first shell 100 and the second shell 200 and manually adjusting the scanning direction, improving scanning efficiency and reducing labor intensity.

[0038] In a preferred implementation scheme, in order to facilitate operation, a second rangefinder 412 is further provided on the first scanning anchor rod, and the horizontal projection of the second rangefinder 412 coincides with the horizontal projection of the support assembly 300 .

[0039] The two first support rods 310 and the two second support rods 320 are respectively arranged at the center of the east, west, top and bottom four side walls of the first shell 100 (the center is a point where the distances from the point to the four sides of the side wall are equal), and the first support rod 310 and the second support rod 320 both extend into the center of the east, west, top and bottom four side walls of the second shell 200, the distances from both ends of the first scanning rod 410 to the center of the side wall of the second shell 200 are the same, and the second rangefinder 412 is arranged in the middle of the first scanning rod 410, and is respectively arranged At the upper and lower sides in the middle of the first scanning rod 410, when the first scanning rod 410 slides from the first support rod 310 extending into the east wall of the second shell 200 to the first support rod 310 on the west wall of the second shell 200, the second rangefinder 412 detects the distance from the first scanning rod 410 to the first support rod 310. When the detected distance reaches a threshold, the first scanning rod 410 stops sliding. The sliding of the first scanning rod 410 is controlled by the second detector, which reduces the manipulation of personnel and makes the operation simpler and more convenient.

[0040] In an optimized solution, in order to consider the comprehensiveness of scanning, the scanning assembly 400 includes at least two second scanning rods 420 , and the second scanning rods 420 are slidably connected to the inner wall of the second shell 200 .

[0041] The first scanning rod 410 is arranged on the east, west, upper and lower side walls of the second shell 200 that cannot be opened. Two second scanning rods 420 are arranged in the second shell 200, and the second scanning rods 420 are respectively arranged on the south and north side walls of the second shell 200 that can be opened. The two second scanning rods 420 slide up and down along the south and north side walls of the second shell 200 respectively. By setting up two second scanning rods 420, the other two surfaces that cannot be scanned by the first scanning rod 410 are scanned, thereby realizing all-round scanning of the sample, making scanning simpler and more convenient.

[0042] In a specific embodiment, a plurality of second cameras 422 and a third rangefinder 421 are disposed on the second scanning rod 420. The second cameras 422 are disposed on the side of the second scanning rod 420 close to the sample, and the third rangefinder 421 is disposed at both ends of the second scanning rod 420 for detecting the distance between the second scanning rod 420 and the inner wall of the second shell 200.

[0043] The second camera 422 can use an existing ranging camera and is distributed in stages on the side of the second scanning rod 420 close to the sample. The third rangefinder 421 is arranged at both ends of the second scanning rod 420, and one third rangefinder 421 is arranged on both sides of the upper and lower ends of one end of the second scanning rod 420. When the second scanning rod 420 slides from top to bottom, the third rangefinder 421 detects that the distance between the second scanning rod 420 and the upper or lower side wall of the second shell 200 reaches a threshold value, and changes the scanning direction so that the second scanning rod 420 changes its sliding direction from top to bottom to bottom to top, thereby realizing the scanning of the sample and making the operation simpler and more convenient.

[0044] In a more preferred embodiment, in order to facilitate sliding, a moving component 500 is also included, and the moving component 500 includes a slide rail 520 and an electric trolley 510. The slide rail 520 is arranged on the inner wall of the second shell 200, and the electric trolley 510 is slidably connected to the slide rail 520 and fixedly connected to the scanning component 400.

[0045] The slide rails 520 are distributed on the east, west, top, bottom, south and north inner walls of the second shell 200. The slide rails 520 on the east, west, top and bottom inner walls of the second shell 200 are surrounded together. The slide rails 520 on the south and north inner walls of the second shell 200 are vertically arranged. Two slide rails 520 are arranged on the inner wall of each second shell 200, and are arranged on both sides of the inner wall of the second shell 200. The electric trolley 510 is clamped on the slide rails 520 by a gear set and can slide along the slide rails 520. The electric trolley 510 is fixedly connected to the first scanning rod 410 and the second scanning rod 420 respectively. The electric trolley 510 drives the first scanning rod 410 and the second scanning rod 420 to slide along the slide rails 520, thereby realizing the sliding of the scanning component 400, making the scanning of the scanning component 400 simpler and more convenient.

[0046] In a better embodiment, for convenience of operation, a control component 600 is further included. The control component 600 is arranged on one side of the first shell 100 and is electrically connected to the moving component 500, the scanning component 400 and the supporting component 300 respectively.

[0047] The control component 600 is arranged on a side of the first shell 100 where the support component 300 is not arranged. The lines of the moving component 500, the scanning component 400 and the support component 300 can be arranged in the buffer zone 110 and fixed on the inner wall of the first shell 100, and finally electrically connected to the control component 600. A support frame is arranged below the first shell 100, and the support frame is detachably connected to the first shell 100. The control component 600 includes a display 610, a processor 620 and a control console 630. The electric trolley 510, the first support rod 310, and the second support rod 320 are all electrically connected to the control console 630. The display 610 is electrically connected to the processor 620, and the processor 620 is respectively connected to the The first rangefinder 411, the second rangefinder 412, the third rangefinder 421, the first camera 413 and the second camera 422 are electrically connected. If the support assembly 300 is equipped with a pressure sensor, the pressure sensor is also electrically connected to the processor 620. The first support rod 310 and the second support rod 320 are pushed or pulled through the control console 630. The processor 620 summarizes the received scanning parameters and displays the scanned sample three-dimensional model and parameters on the display 610. The control assembly can be a WeChat applet or software. Through data transmission, the operation handle is simulated on the mobile phone to operate it. The scanning results are displayed more intuitively through the display 610, the operation is simpler, and the scanning parameters are more convenient to retrieve.
