The lifting mechanism 40 consists of several telescopic drivers 41 with suction cups 42 connected to their telescopic ends. The body of the telescopic driver 41 is fixed on the frame 10. The suction cups 42 are used to adsorb and fix the board. The adsorption surface of the suction cups 42 faces upward. The scraping mechanism 50 is located above the board placement area. The scraping mechanism 50 includes a scraping device 51 and a transmission device 52. The scraping device 51 can perform the scraping operation of the board 80 by moving along the front-back or left-right direction through the transmission device 52.

[0020] This embodiment requires the use of a robotic arm and a suction cup holder. The robotic arm is installed at the rear end of the automatic edge scraping device for the board. The boards are stacked and placed on one side of the robotic arm. The robotic arm is equipped with a suction cup holder for adsorbing the board 80.

[0023] Compared to manual edge scraping devices, this application achieves automatic edge scraping, which greatly reduces the production cost of manual operation and improves operational safety and production efficiency. Compared to setting an edge trimming device on each of the four sides of the board 80, this application uses a transmission device 52 to carry a single edge scraping device 51 that moves circumferentially along the edge of the board 80 to perform edge scraping operations on each side of the board 80, which improves the utilization efficiency of production tools and helps to save production resources and improve production efficiency.

[0024] Furthermore, the left and right adjustment mechanism 20 consists of two drive components 60, which are fixed on the left and right sides of the plate placement area 11 and arranged axially symmetrically with respect to the front and back directions.

[0025] One way to adjust the left and right position of the board 80 in this embodiment is as follows: the drive component 60 located on the left side of the board placement area 11 pushes the board 80 to the right, and the drive component 60 located on the right side of the board placement area 11 pushes the board 80 to the left. The two drive components 60 work together to center the board 80 relative to the left and right sides of the board placement area 11, thereby achieving the effect of quickly centering and positioning the board.

[0026] Furthermore, the front and rear adjustment mechanism 30 consists of two drive components 60 and two limit components 31. The two drive components 60 are fixed side by side on the front side of the plate-laying area 11, and the two limit components 31 are fixed side by side on the rear side of the plate-laying area 11.

[0027] In this embodiment, one way to adjust the front and rear position of the board 80 is as follows: two drive components 60 located on the front side of the board placement area 11 jointly push the board 80 to move backward until the rear side of the board 80 abuts against the limiting component 31, thereby achieving the effect of rapid front and rear positioning of the board.

[0028] In a preferred embodiment, the drive assembly 60 includes a linear drive device 61 and an auxiliary component 62. The auxiliary component 62 has a right-angled trapezoidal structure. The drive end of the linear drive device 61 is provided with a rectangular plate, which is fixedly connected to the right-angled side of the auxiliary component 62. The right-angled side of the auxiliary component 62 is perpendicular to the long side of the rectangular plate. The inclined side of the auxiliary component 62 is set towards the plate placement area 11 and can be used to guide the plate 80 to be placed flat. The linear drive device 61 pushes the auxiliary component 62 to move horizontally, and the inclined side of the auxiliary component 62 contacts the edge of the plate 80, pushing the plate 80 to achieve rapid centering and positioning.

[0029] In a preferred embodiment, the limiting component 31 is a stop bar. The limiting component 31 is vertically disposed on the rear side of the plate placement area 11 and fixedly connected to the support arm 113. The limiting component 31 is used to limit the rear position of the plate 80.

[0030] Furthermore, the telescopic actuator 41 is a cylinder, and the frame 10 is provided with a connecting piece 12. The body of the telescopic actuator 41 is fixedly connected to the frame 10 through the connecting piece 12.

[0031] In a preferred embodiment, this embodiment provides a total of twelve telescopic actuators 41, which are arranged around the plate-laying area 11: six telescopic actuators 41 are spaced apart along the left-right direction on the front side of the plate-laying area 11, two telescopic actuators 41 are respectively arranged along the front-back direction on the left and right sides of the plate-laying area 11, and two telescopic actuators 41 are arranged at each end of the rear side of the plate-laying area 11; this method of arranging the telescopic actuators 41 around the plate strengthens the fixing effect on the edge of the plate 80, prevents the plate 80 from shifting during the lifting and scraping process, and helps to improve the safety and stability of the production equipment operation.

[0032] As a preferred embodiment, the suction cup 42 is a vacuum suction cup. By adjusting the air pressure between the suction cup 42 and the plate 80, the fixing and releasing operations of the plate 80 can be realized. Compared with traditional clamps that often need to be adjusted, the suction cup 42 has higher working efficiency, effectively reduces the risk of plate slippage, and ensures the stability of the edge scraping process.

[0033] Furthermore, the scraping device 51 includes a connector 511 for connecting the transmission device 52, a steering drive device 512, and several scrapers 514. The body of the steering drive device 512 is fixed to the lower end of the connector 511. The drive shaft of the steering drive device 512 is connected to a blade holder 513. The scrapers 514 are fixed to the lower end of the blade holder 513. The rotation drive device 512 is used to rotate the blade holder 513 to realize the scraping operation on all four sides of the plate 80.

[0034] In this example, the transmission device 52 drives a single scraping device 51 to move left and right or back and forth to achieve the scraping operation of the edge of the board 80. Therefore, when the linear movement direction of the scraping device 51 changes, the orientation of the blade holder 513 is also adjusted so that the blade of the scraper 514 can contact the edge of the board 80. The scraping device 51 rotates the blade holder 513 clockwise or counterclockwise by 90° through the steering drive device 512 so that the blade of the scraper 514 can be aligned with the four sides of the board 80. Then, the distance between the blade and the edge of the board 80 is adjusted to carry out the scraping operation.

[0035] Furthermore, in this embodiment, the plurality of scrapers 514 comprises two front scrapers 5141 and two rear scrapers 5142. One front scraper 5141 and one rear scraper 5142 form a set of tools, and the plurality of scrapers 514 form two sets of tools. The two sets of tools are rotatably arranged on both sides of the tool holder 513 along its length. The two front scrapers 5141 are centrally symmetrically arranged with respect to the rotation axis of the tool holder 513, and the two rear scrapers 5142 are centrally symmetrically arranged with respect to the rotation axis of the tool holder 513, such that one front scraper 5141 and one rear scraper 5142 are respectively arranged on both sides of the tool holder 513 along its width. The steering drive device 512 rotates the tool holder 513, allowing the front scrapers 5141 and rear scrapers 5142 on different sides to be used alternately, which helps to prevent tool fatigue, increase durability, and reduce the frequency of tool replacement.

[0036] In a preferred embodiment, the front scraper 5141 and the rear scraper 5142 of the same set of tools are connected by a rotating seat 516. The rotating seat 516 is a square structure with a through hole in the center. The left and right ends of the rotating seat 516 are respectively connected to a front scraper 5141 and a rear scraper 5142. A fixed shaft 518 is provided on each side of the tool holder 513 along its length. The rotating seat 516 is sleeved on the fixed shaft 518 through the through hole. The rotating seat 516 can rotate around the axis of the fixed shaft 518. A reset component 517 is provided on the rotating seat 516 for returning the front scraper 5141 and the rear scraper 5142 to their original position. The reset component 517 is a torsion spring. The body of the torsion spring is sleeved on the fixed shaft 518, and one torsion arm is fixed to the upper end of the fixed shaft 518. The other torsion arm is fixed to the top of the rotating seat 516 by a positioning post.

[0037] In a preferred embodiment, the front scraper 5141 is an inverted right-angled trapezoid with the hypotenuse of the trapezoid serving as the cutting edge, and the rear scraper 5142 is a rectangle with one of its long sides serving as the cutting edge. The backs of the front scraper 5141 and the rear scraper 5142 are connected to the rotating base 516. The lower ends of both the front scraper 5141 and the rear scraper 5142 are inclined toward the rotation axis of the blade holder 513, so that the front scraper 5141 and the rear scraper 5142 on both sides of the width direction of the blade holder 513 are arranged in an inverted V-shape.

[0038] Combining the shapes and arrangements of the front scraper 5141 and the rear scraper 5142, and with the combined cooperation of the rotating seat 516, the reset assembly 517, the fixed shaft 518, and the steering drive device 512, the scraping process of the scraping device 51 on one side of the plate 80 is as follows: The scraping device 51 moves to the outer perimeter of one corner of the plate 80. The steering drive device 512 rotates the front scraper 5141 on one side of the width direction of the knife holder 513 as the feed knife. The scraping device 51 moves so that the front scraper 5141 contacts the plate 80. After the front scraper 5141 deflects and adjusts to a suitable scraping angle, the scraping device 51 begins to move along the side of the plate 80 for scraping. During the movement, the front scraper 5141 and the rear scraper 5142 located on one side of the width direction of the knife holder 513 contact the plate 80 and undergo scraping. The deflection causes the corresponding rotating seat 516 to rotate around the axis of the fixed shaft 518. The torsion arm fixed on the rotating seat 516 rotates with the rotating seat 516 around the axis of the fixed shaft 518. The body of the reset assembly 517 deforms, and the torsion arm connected to it provides a counterforce to the positioning post to limit the rotation of the rotating seat 516. This causes the front scraper 5141 and the rear scraper 5142 to press against the edge of the plate 80 and form a V-shaped cutter head in the feeding direction, with the opening of the V-shaped cutter head facing the edge of the plate 80. The front scraper 5141 and the rear scraper 5142 respectively perform chamfering and scraping treatment on the upper and lower edges of the plate 80. After the scraping is completed, the front scraper 5141 and the rear scraper 5142 leave the plate 80, and the reset assembly 517 releases the elastic potential energy generated by the deformation of its body, causing the rotating seat 516 to rotate back to the center.

[0039] In the preferred embodiment of the scraping device 51, it is convenient to simultaneously perform chamfering and trimming on the upper and lower edges of the plates 80 of different thicknesses. Furthermore, the movable trimming method of the cutter helps to reduce the stress between the cutter and the plate 80, making the trimming operation smoother and extending the service life of the cutter.

[0040] Furthermore, the scraping device 51 also includes a brush plate 515 disposed on the knife holder 513. The brush plate 515 is arranged around the four scrapers 514 along the length and width of the knife holder 513. The brush plate 515 is used to block the scraped scrap and make it fall into the waste hopper 70 as much as possible, effectively preventing the scrap from splashing into the scraping device during the scraping process and causing adverse effects.

[0041] Furthermore, the transmission device 52 includes a first linear module 521 and two second linear modules 522 respectively disposed on the left and right sides of the frame 10. The two second linear modules 522 are parallel to each other and fixed above the frame 10. The first linear module 521 and the second linear modules 522 are arranged perpendicular to each other. The two ends of the first linear module 521 are slidably connected to the two second linear modules 522 through slides 523 respectively. The scraping device 51 is connected to the first linear module 521.

[0042] In this embodiment, the scraping mechanism 50 scrapes the edge of the board 80 in the following manner: If the left and right sides of the board are scraped, such as Figure 5 The scraping device 51 is located on the right rear side of the plate 80. Through the steering drive device 512 and the transmission device 52, the front scraper 5141 is made to fit the plate 80 and deflect to a suitable scraping angle. Then, the second linear module 522 drives the first linear module 521 to move forward, which drives the scraping device 51 to perform scraping operation on the right side of the plate 80. The scraping operation on the left side is similar to the above process and will not be described in detail here. If the front and back sides of the 80mm sheet are scraped, such as Figure 6 The scraping device 51 is located on the right front side of the plate 80. Through the steering drive device 512 and the transmission device 52, the front scraper 5141 is made to fit the plate 80 and deflect to a suitable scraping angle. Then, the first linear module 521 drives the scraping device 51 to move to the left to perform scraping operation on the front side of the plate 80. The scraping operation on the rear side is similar to the above process and will not be described in detail here.

[0043] In a preferred embodiment, seven long plates 111, two wide plates 112, and two support arms 113 are provided around the plate placement area 11 for placing the plate 80. The five long plates 111 are fixed at intervals along the left and right directions on the front side of the plate placement area 11. The two wide plates 112 are fixed on the left and right sides of the plate placement area 11, respectively. The two support arms 113 are fixed on the rear side of the plate placement area 11, and each of the two support arms 113 is fixedly connected to one of the long plates 111 above it. According to the actual layout of the telescopic actuator 41, the corresponding long plates 111 and wide plates 112 are provided with mating notches for the telescopic end of the telescopic actuator 41 to pass through. The two wide plates 112 are U-shaped, and the end near the drive assembly 60 is provided with a notch for the drive assembly 60 to move into.
