Description

Technical Field

[0001] The utility model relates to the technical field of trusses, and in particular to a horizontal moving device, a truss and an intelligent loading and unloading production line. Background Art

[0002] In automated welding and cutting production lines, automatic trusses are commonly used to carry out various process processing in order to improve production efficiency. For example, during the plate conveying process, the end picker under the automatic truss adsorbs and fixes the workpiece, and with the corresponding visual recognition device, the truss automatically lifts it accurately to the designated position, realizing the automation and intelligence of loading and unloading before welding and cutting.

[0003] However, for old factories with restricted height or factories with low roofs, when installing automatic truss equipment, the top height of the lifting arm is very high when it is raised to the highest point, which often exceeds the height limit of old factories or factories with low roofs, making it impossible to install ordinary trusses in these factories, affecting the automation and intelligent transformation of the welding production line. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a horizontal moving device for a truss, the horizontal moving device comprising:

[0005] A base, arranged at the transverse track of the truss, the base being used to move along the transverse track;

[0006] A lower extension mechanism is disposed at the base, and the lower extension mechanism extends downward to below the base; and

[0007] A lifting arm, which is arranged upright and is in transmission connection with the lower extension mechanism via a first transmission component, and the lifting arm is used for lifting and lowering along the lower extension mechanism;

[0008] Wherein, when the lifting arm descends to the end of the bottom stroke, the top end height of the lifting arm is lower than the top surface of the base.

[0009] Optionally, the lower extension mechanism comprises:

[0010] A vertical plate, which is a rectangular plate-shaped structure arranged vertically, and the vertical plate is connected to the bottom of the base; and

[0011] A plurality of reinforcing ribs respectively connect the vertical plate and the base.

[0012] Optionally, the vertical plate and the base are made as one piece.

[0013] Optionally, the reinforcing rib is a frame structure.

[0014] The side of the reinforcing rib is connected to the plate surface of the vertical plate, and the top edge of the reinforcing rib is connected to the bottom surface of the base.

[0015] Optionally, the lifting arm is in the shape of a column. When the lifting arm descends to the end of the bottom stroke, the top end of the lifting arm is lower than the bottom surface of the base.

[0016] Optionally, the horizontal moving device further includes a lifting drive motor, and the lifting drive motor is arranged on the base or the lower extension mechanism;

[0017] The first transmission component includes a first gear and a rack that mesh with each other. The first gear is connected to the lifting drive motor, and the rack is vertically arranged at the lifting arm.

[0018] Optionally, the horizontal moving device further includes a safety brake and a transverse movement drive motor.

[0019] The transverse movement drive motor is used to drive the base to move along the transverse movement track.

[0020] The second gear in the safety brake meshes with the rack;

[0021] The safety brake, the lifting drive motor and the transverse movement drive motor are vertically arranged on one side of the lifting arm.

[0026] In addition, the present invention also provides an intelligent loading and unloading production line, including the truss.

[0027] The technical effects of the present invention at least include:

[0028] In the present utility model, in view of the above problems existing in the existing truss, a lower extension mechanism is added between the existing base and the lifting arm. In particular, the lower extension mechanism is used to extend downward below the base. Without affecting the lifting stroke of the lifting arm and ensuring that the height of the lower end of the truss transverse movement track remains unchanged, the height of the lifting arm is reduced. This also enables the top height of the lifting arm to be lower than the top surface of the base when the lifting arm moves downward to the bottom of the stroke, and even makes the top height of the lifting arm completely lower than the height of the bottom surface of the base. Thus, when the lifting arm rises to the top of the stroke, its top height is significantly reduced to meet the ceiling height limit of old factories or factories with low ceilings, while not affecting the normal use of the truss, ensuring the smooth installation and use of the truss in the factory with low ceilings, and ensuring the smooth progress of the subsequent automation and intelligent transformation of the welding and cutting production lines.

[0038] SeeFigure 1 and Figure 2 , this embodiment provides a horizontal moving device for a truss, the horizontal moving device comprising:

[0039] A base 1 is arranged at a transverse track 11 of the truss, and the base 1 is used to move along the transverse track 11;

[0040] A lower extension mechanism 2 is disposed on the base 1, and the lower extension mechanism 2 extends downward to below the base 1; and

[0041] A lifting arm 3, which is arranged upright and is in transmission connection with the lower extension mechanism 2 via a first transmission component, and the lifting arm 3 is used for lifting and lowering along the lower extension mechanism 2;

[0042] When the lifting arm 3 descends to the end of the bottom stroke, the top end of the lifting arm 3 is lower than the top surface of the base 1 .

[0043] It should be noted that the lower extension mechanism 2 here can be a frame structure, or can be formed by splicing plate-like structures, as long as the lower extension mechanism 2 can effectively support and connect the lifting arm 3.

[0044] In the present invention, in view of the above-mentioned problems existing in the existing trusses, the inventor of the present invention has found through analysis that when the lifting arm in the prior art is raised to a high point, there is still a certain space between its bottom end and the bottom of the transverse track. In view of this finding, the present invention adds a lower extension mechanism 2 between the existing base 1 and the lifting arm 3, and especially utilizes the lower extension mechanism 2 to extend downward to the bottom of the base 1, so as to reduce the height of the lifting arm 3 without affecting the lifting stroke of the lifting arm 3 and ensuring that the height of the lower end of the truss transverse track remains unchanged. This also makes the top height of the lifting arm 3 lower than the top surface of the base 1 when the lifting arm 3 moves downward to the bottom of the stroke, and even makes the top height of the lifting arm 3 completely lower than the height of the bottom surface of the base 1; so that when the lifting arm 3 rises to the top of the stroke, its top height is greatly reduced to meet the height limit of the roof of the old factory building or the factory building with a low roof, and at the same time does not affect the normal use of the truss, ensuring the smooth installation and use of the truss in the above-mentioned factory building with a low roof, and ensuring the smooth progress of the subsequent automation and intelligent transformation of the welding production line.

[0045] See also Figure 1 and Figure 2 , further, the lower extension mechanism 2 comprises:

[0046] The vertical plate 21 is a rectangular plate-shaped structure arranged vertically, and the vertical plate 21 is connected to the bottom of the base 1; and

[0047] A plurality of reinforcing ribs 22 respectively connect the upright plate 21 and the base 1.

[0048] The upright plate 21 reduces the occupied space of the lower extension mechanism 2, and the reinforcing ribs 22 cooperate with the upright plate 21 to improve the support strength and stiffness of the lower extension mechanism 2.

[0049] See Figure 1 and Figure 2 Furthermore, the upright plate 21 and the base 1 are made integrally.

[0050] It is convenient for the manufacture of the lower extension mechanism 2.

[0051] See Figure 1 and Figure 2 Furthermore, the reinforcing rib 22 is of a frame structure.

[0052] The side of the reinforcing rib 22 is connected to the plate surface of the upright plate 21, and the top edge of the reinforcing rib 22 is connected to the bottom surface of the base 1.

[0053] By using the frame structure, the weight of the reinforcing rib 22 is reduced, and at the same time, the effective support of the reinforcing rib 22 for the base 1 and the upright plate 21 is ensured.

[0054] See Figure 1 and Figure 2 Furthermore, the lifting arm 3 is of a columnar structure. When the lifting arm 3 descends to the end of the bottom stroke, the top of the lifting arm 3 is lower than the bottom surface of the base 1.

[0055] The top of the lifting arm 3 is lower than the bottom surface of the base 1 to make full use of the connection function of the lower extension mechanism 2 between the base 1 and the lifting arm 3, so as to effectively reduce the height of the lifting arm 3.

[0056] See Figure 1 and Figure 2 Furthermore, the horizontal moving device further includes a lifting drive motor 31, and the lifting drive motor 31 is arranged at the base 1 or the lower extension mechanism 2.

[0057] The first transmission component includes a first gear and a rack that mesh with each other. The first gear is connected to the lifting drive motor 31, and the rack is vertically arranged at the lifting arm 3.

[0058] By using the cooperation of the lifting drive motor 31, the first gear and the rack, the lifting arm 3 is lifted and lowered along the lower extension mechanism 2.

[0059] Preferably, both the first gear and the rack are of helical tooth structures, that is, the first gear is a helical gear. Of course, both the first gear and the rack can also be spur gears, or other types of gears, as long as power transmission can be achieved.

[0060] See Figure 1 and Figure 2 , further, the horizontal moving device further includes a safety brake 32 and a crosswise driving motor 33,

[0061] The crosswise driving motor 33 is used to drive the base 1 to move along the crosswise rail 11,

[0062] The second gear in the safety brake 32 meshes with the rack;

[0063] The safety brake 32, the lifting driving motor 31 and the crosswise driving motor 33 are arranged vertically on one side of the lifting arm 3.

[0064] By arranging the safety brake 32, the lifting driving motor 31 and the crosswise driving motor 33 vertically on one side of the lifting arm 3, the width of the lower extension mechanism 2 is reduced, thereby expanding the moving range of the horizontal moving device and reducing the crosswise restriction it receives.

[0065] See Figure 1 and Figure 2 , further, the horizontal moving device further includes:

[0066] An end effector 33, arranged at the bottom end of the lifting arm 3, and the end effector 33 rotates a set angle in the horizontal plane relative to the lifting arm 3 through a rotating motor and a corresponding second transmission component, and the end effector 33 is used for adsorbing workpieces;

[0067] A vision sensor, arranged at the bottom end of the lifting arm 3, and the vision sensor is arranged facing downward of the end effector 33.

[0068] Preferably, the vision sensor may include a line laser and a ccd camera, and the two cooperate with each other to detect spatial dimensions, realize the identification of workpiece skew, and then the end effector 33 rotates a corresponding set angle in the horizontal plane relative to the lifting arm 3 through the rotating motor and the corresponding second transmission component to straighten the workpiece. Realize the intelligence of the truss self-hoisting.

[0069] In addition, this embodiment also provides a truss, including the horizontal moving device.

[0070] Since the technical effects obtained by this truss are the same as those of the horizontal moving device, the truss will not be further explained.

[0071] In addition, this embodiment also provides an intelligent loading and unloading production line, including the truss.

[0072] The intelligent loading and unloading production line in this embodiment can be the intelligent loading and unloading production line pointed out in "An Intelligent Steel Plate Cutting System and Method (202211253993.9)", or other types of intelligent steel plate cutting production equipment, as long as it can independently realize the whole process from scribing and inkjet coding, cutting and blanking, waste material cutting, automatic sorting of parts, bevel cutting, chamfering, material sorting and palletizing to waste material treatment.

[0073] Since the technical effects achieved by this intelligent loading and unloading production line are the same as those of the truss, the intelligent loading and unloading production line will not be further explained.
