Description

Technical Field

[0001] The utility model relates to the technical field of engineering board quality inspection, in particular to a lifting and placing mechanism for engineering board detection. Background Art

[0002] An engineering board is a building material, also known as a density board or medium density fiberboard. It is a board made of fiber materials and wood particles under high pressure. Because of its relatively high density and strength, it has a wide range of applications in construction, decoration, furniture manufacturing, etc.

[0003] As an engineering material, its hardness, density, surface workability, etc. are all important prerequisites for subsequent construction operations. Therefore, before the engineering board leaves the factory, it has to undergo quality inspection by a professional surveying agency. In the existing inspection process, the engineering board is manually carried and placed to the inspection station. In the case of repeated inspection operations, the above method is obviously time-consuming and laborious. For this reason, we propose a lifting and placing mechanism for engineering board detection to solve the above problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects existing in the prior art. The utility model proposes a lifting and placing mechanism for engineering board detection that can servo-repeatably extract the engineering board to the inspection table.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is: a lifting and placing mechanism for engineering board detection, including: a frame, a connecting rod assembly arranged on one side of the frame, a driving member fixed at the bottom of the frame, a driving shaft rotatably connected to the frame, and an adsorption block. The connecting rod assembly includes a driving rod, a swing rod, and a linkage rod. One end of the driving rod is coaxially fixed to the shaft section of the driving shaft exposed outside the frame, and the other end is hinged to the end of the swing rod through a movable pin. The end of the swing rod away from the movable pin is hinged to the middle-section extension of the linkage rod. One end of the linkage rod is rotatably connected to the side of the frame, and the other end is vertically fixed with a connecting rod. A guide block is also fixed to the top side of the frame. The center of the back of the adsorption block is fixed with a guide rod and is slidably connected to the guide block through the guide rod. The driving member is used to servo-drive the driving shaft to rotate, and the length of the guide rod is set to be not less than twice the length of the driving rod.

[0006] Further, the frame includes a vertical backboard and support plates symmetrically fixed on both sides of the backboard. The vertical ends of the backboard are concave and are fixed to the support plates by screws one by one. The two support plates are fixed together by multiple groups of fixing rods at the upper and lower ends respectively. The driving member is located at the bottom between the two support plates. A first positioning table and a second positioning table are also fixed on the outer side of one of the support plates. The first positioning table and the second positioning table are respectively fixed to the support plate by fixing flanges with screws and are respectively connected to the guide block and the linkage rod.

[0007] Further, the driving member includes a servo motor, a worm gear, and a worm. The servo motor is fixed on the inner side of the support plate, and its output end is coaxially fixed to the worm. The worm gear is coaxially fixed to the driving shaft, and the worm gear meshes with the worm.

[0008] Further, the servo motor is located at the bottom between the two support plates.

[0009] Further, the driving rod, the swing rod, and the linkage rod are all provided with leakage grooves at their centers.

[0010] Further, a reinforcing plate is also fixed between the connecting rod and the linkage rod bracket.

[0011] Further, vacuum suction cups are fixed at the four corners of the bottom of the adsorption block.

[0012] Compared with the prior art, the beneficial effects of the present utility model include: the installation requirements in the height direction are solved by the erected frame, and then the connecting rod assembly reciprocates and swings on one side of the frame. After multiple transmissions, the guide rod is driven to servo up and down, and then the guide rod drives the adsorption block to adsorb and extract the engineering board. After sending it to the corresponding operation height table, the quality inspection of the engineering board is carried out, which greatly improves the efficiency of the repeated inspection operation of the engineering board. The overall structure is reasonably designed, practical and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] It is easy to understand that according to the technical solution of the present utility model, without changing the essential spirit of the present utility model, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following specific embodiments and the accompanying drawings are only exemplary illustrations of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0018] According to an embodiment of the present utility model, in combination with Figure 1 - Figure 2 shown.

[0019] In this embodiment, for the overall structure of the cigarette, a lifting and lowering mechanism for engineering board detection includes: a frame 1, a connecting rod assembly 2 arranged on one side of the frame 1, a driving member 3 fixed to the bottom of the frame 1, a driving shaft 4 rotatably connected to the frame 1, and an adsorption block 5. The connecting rod assembly 2 includes a driving rod 6, a swinging rod 7, and a linkage rod 8. One end of the driving rod 6 is coaxially fixed to the shaft section of the driving shaft 4 exposed outside the frame 1, and the other end is hinged to the end of the swinging rod 7 through a movable pin 9. The end of the swinging rod 7 away from the movable pin 9 is hinged to the middle section extension of the linkage rod 8. One end of the linkage rod 8 is rotatably connected to the side of the frame 1, and the other end is vertically fixed with a connecting rod 10. A guide block 11 is also fixed to the top side of the frame 1. The center of the back of the adsorption block 5 is fixed with a guide rod 12 and is slidably connected to the guide block 11 through the guide rod 12. The driving member 3 is used to servo-drive the driving shaft 4 to rotate, and the length of the guide rod 12 is set to be not less than twice the length of the driving rod 6.

[0020] The following is a specific description of each structural member. For the frame 1, the frame 1 includes a vertical backboard 13 and support plates 14 symmetrically fixed on both sides of the backboard 13. The vertical ends of the backboard 13 are concave and are fixed to the support plates 14 by screws one by one. The two support plates 14 are fixed together by multiple groups of fixing rods 15 at the upper and lower ends respectively. The driving member 3 is located at the bottom between the two support plates 14. A first positioning table 16 and a second positioning table 17 are also fixed to one outer side of the support plate 14. The first positioning table 16 and the second positioning table 17 are respectively fixed to the support plate 14 by fixing flanges 18 and are respectively connected to the guide block 11 and the linkage rod 8 correspondingly.

[0021] The driving member 3 includes a servo motor 19, a worm gear 20, and a worm 21. The servo motor 19 is fixed on the inner side of the support plate 14, and its output end is coaxially fixed to the worm 21. The worm gear 20 is coaxially fixed to the driving shaft 4, and the worm gear 20 is in meshing engagement with the worm 21.

[0022] The servo motor 19 is located at the bottom between the two bracket plates 14. The driving rod 6, the swing rod 7 and the linkage rod 8 are all provided with a leakage groove 22 at the center. The connecting rod 10 and the linkage rod 8 bracket are also fixed with a reinforcement plate 23. The four corners of the bottom of the adsorption block 5 are fixed with vacuum suction cups 24.

[0023] According to the above structure record, during the engineering board inspection operation, in order to avoid repeated manual lifting of the engineering board, the utility model solves the installation requirements in the height direction through an upright frame 1, and then reciprocates through the connecting rod assembly 2 on one side of the frame 1, and after multiple transmissions, drives the guide rod 12 servo to rise and fall, and then the guide rod 12 drives the adsorption block 5 to adsorb and extract the engineering board, and sends it to the corresponding operating height table to carry out engineering board quality inspection.

[0024] Specifically, the present application does not simply adopt the conventional electric push rod lifting method. First, considering that the output stroke of the electric push rod is limited, and second, the electric push rod itself is difficult to coordinate the adsorption and relaxation of the engineering board. Based on the above considerations, the present application adopts a drying component composed of a driving rod 6, a swing rod 7 and a linkage rod 8. During the transmission process, the driving rod 6 is driven to rotate by the servo motor 19 and the driving shaft 4, and synchronously drives the swing rod 7 hinged thereto to swing. Since one end of the linkage rod 8 itself is rotatably connected to the frame 1 and the other end is a movable end, the swing rod 7 extends in the middle section of the linkage rod 8. After the parts are hinged, the rotation of the driving rod 6 can be converted into the up and down swinging of the movable end of the linkage rod 8 under the transmission of the swing rod 7. At the same time, the movable end is used to connect the adsorption block 5, and because the guide block 11 limits the guide rod 12, the guide rod 12 is fixed on the back of the adsorption block 5. Finally, the rotation of the driving rod 6 is converted into the up and down lifting of the guide rod 12 in the guide block 11, and the engineering board is sucked and grasped by the vacuum suction cups 24 at the four corners of the bottom. After the vacuum suction cup 24 is connected to the external pneumatic control unit, it can be lifted and placed at a fixed point, which greatly improves the convenience of the engineering board detection process.

[0025] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
