Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum template processing equipment, and particularly relates to an easy-to-operate robot automatic welding equipment applied to aluminum template processing. BACKGROUND

[0002] At present, more and more cement pouring molds for buildings adopt aluminum molds, which are also called aluminum templates. The aluminum molds are much more convenient than traditional wooden molds and steel molds, and are convenient for hoisting, lifting, repeated use and the like. Referring to Figure 13 , the common aluminum template mainly comprises a U-shaped template main body A, a front sealing plate B and a rear sealing plate C respectively arranged at two ends, and a supporting rib D arranged in a groove cavity of the template main body A. When the aluminum template is processed, in order to ensure the structural strength of the aluminum template, the welding parts such as the front sealing plate B, the rear sealing plate C and the supporting rib D are usually welded on the template main body A in a full welding manner.

[0003] In the prior art, since the aluminum templates have different length and width sizes, the welding positions of the front sealing plate B, the rear sealing plate C and the supporting rib D on the template main body A need to be adjusted according to the length and width sizes of the aluminum templates. At present, there are three welding methods for welding the front sealing plate B, the rear sealing plate C and the supporting rib D on the template main body A. The first method is that some manufacturers manually and flexibly adjust the positions of the welding parts such as the front sealing plate B, the rear sealing plate C and the supporting rib D according to production drawings, and then use a pure manual welding method to fully weld the welding parts such as the front sealing plate B, the rear sealing plate C and the supporting rib D on the template main body A. Although this method can weld the welding parts such as the front sealing plate B, the rear sealing plate C and the supporting rib D to the corresponding positions according to different aluminum template production requirements, the manual adjustment of the positions of the welding parts takes a long time, and the manual full welding of the welding parts is slow, which is not conducive to the rapid production of the aluminum template.

[0004] The second method is that some manufacturers first manually and flexibly adjust and spot weld the positions of the welding parts such as the front sealing plate B, the rear sealing plate C and the supporting rib D according to production drawings, then transfer the aluminum template with the welding parts to a full welding device, and then use a welding robot of the full welding device to fully weld the welding parts. However, this method also has the problems of long time and low efficiency of manual adjustment of the positions of the welding parts.

[0005] The third is that some manufacturers use positioning mold frame to position, preform the mold frame with the same size as the aluminum template to be welded, reserve the welding position of the support rib D in the mold frame, and then set the mold frame on the aluminum template, and then put the support rib D into the welding position and spot weld by manual or mechanical. Although this process can reduce the error of manual measurement, the length of the aluminum template is a non-standard parameter, the welding position of the internal support rib D has N changes, and a large number of positioning mold frames need to be prepared, which also requires huge production cost. Similarly, since the length of the aluminum template is a non-standard parameter, professional robot engineers need to re-adjust the welding robot for each change of the aluminum template, which requires a lot of adjustment time.

The aluminum template discharging mechanism 5 is connected and controlled by the electrical control device 3.

[0035] ​​Further, the spot welding frame 11 is provided with a welding part positioning mechanism 6, which comprises a welding part positioning arm 61, a positioning action mechanism 62 for driving the welding part positioning arm 61 to move longitudinally along the spot welding station 13 and in and out of the spot welding station 13, and a control switch 7 provided on the welding part positioning arm 61 for controlling the positioning action mechanism 62 in cooperation with the electrical control device 3, wherein the positioning action mechanism 62 and the control switch 7 are both electrically connected with the electrical control device 3; after the spot welding worker completes a spot welding process using the spot welding machine, the worker triggers the control switch 7 by hand, the control switch 7 sends an electrical signal to the electrical control device 3, and the electrical control device 3 controls the spot welding device 1 to perform the next action according to the electrical signal.

[0036] When performing spot welding, the spot welding worker pre-loads the length and width parameters of the template main body A and the position parameters of the front sealing plate B, the rear sealing plate C and the support rib D into the electrical control device 3, and controls the automatic welding equipment to work through the electrical control device 3. First, the template main body A is loaded onto the spot welding station 13, and then the electrical control device 3 controls the welding part positioning movement mechanism 621 to act, the welding part positioning movement mechanism 621 drives the alignment and fitting surface of the welding part positioning arm 61 to move to the front end of the template main body A, the positioning and overturning mechanism 622 acts to drive the welding part positioning arm 61 to swing into the spot welding station 13, at this time, the spot welding worker only needs to put the front sealing plate B into the front end of the template main body A to fit the alignment and fitting surface of the welding part positioning arm 61, which is the welding position of the front sealing plate B and the template main body A, and the spot welding worker can directly perform spot welding; after completing the spot welding of the front sealing plate B, the welding worker triggers the control switch 7, the electrical control device 3 controls the positioning and overturning mechanism 622 to act according to the electrical signal sent by the control switch 7, the positioning and overturning mechanism 622 drives the welding part positioning arm 61 to swing away from the spot welding station 13, the welding part positioning movement mechanism 621 drives the welding part positioning arm 61 to move to the next welding position, the positioning and overturning mechanism 622 drives the welding part positioning arm 61 to swing back into the spot welding station 13 again, and the spot welding worker only needs to put the support rib D into the template main body A to fit the alignment and fitting surface of the welding part positioning arm 61, which is the welding position of the support rib D and the template main body A, and the spot welding worker can directly perform spot welding; in the same way, the spot welding of the remaining support ribs D and the rear sealing plate C is completed, and the control switch 7 also needs to be triggered after the spot welding of the support ribs D and the rear sealing plate C, so that the positioning action mechanism 62 works and the electrical control device 3 calls the corresponding full welding processing program.

[0037] Meanwhile, during the spot welding process, the electrical control device 3 calls the pre-recorded full welding machining programs according to the electrical signals sent by the control switch 7, so that after the aluminum template moves to the full welding station 23, the electrical control device 3 controls the corresponding positions to be full welded according to the pre-recorded full welding machining programs, so as to match the welding positions of the spot welding device 1 and the full welding equipment, and improve the full welding precision of the aluminum template. For example, there are seven kinds of conventional aluminum template widths, and the programmers write the full welding machining programs of the front sealing plate B, the rear sealing plate C and the support rib D corresponding to each width of the aluminum template and record them in the electrical control device 3. There are seven full welding machining programs of the front sealing plate B, seven full welding machining programs of the rear sealing plate C and seven full welding machining programs of the support rib D, that is, a total of 21 full welding machining programs. The electrical control device 3 calls the pre-recorded full welding machining programs according to the electrical signals sent by the control switch 7, so that after the aluminum template moves to the full welding station 23, the electrical control device 3 controls the welding robot 22 to full weld the corresponding positions according to the pre-recorded full welding machining programs.

[0038] Through the above structure, the spot welder can pre-input the length and width parameters of the template main body A and the position parameters of the front sealing plate B, the rear sealing plate C and the support rib D into the electrical control device 3, and then put the welding piece into the spot welding position according to the position of the welding piece positioning arm 61 for spot welding. The whole process does not need the spot welder to measure and position the welding position, can realize the rapid positioning of the spot welding position, greatly speeds up the spot welding efficiency, reduces the technical requirements of the aluminum template processing on the spot welder, and can reduce the processing cost. At the same time, the welding worker does not need to write the full welding program according to the width of the aluminum template, thereby saving the human resources of senior technical personnel.

[0039] As a preferred embodiment, referring to Figures 2-7 The positioning action mechanism 62 includes a welding piece positioning moving mechanism 621 for driving the welding piece positioning arm 61 to move longitudinally along the spot welding station 13 and a positioning overturning mechanism 622 for driving the welding piece positioning arm 61 to swing in and out of the spot welding station 13.

One end of the positioning and overturning telescopic cylinder 6222 is hingedly connected to the longitudinal positioning seat 6212, and the other end is hingedly connected to the positioning and overturning linkage 6223. When the piston rod of the positioning and overturning telescopic cylinder 6222 extends and retracts, the positioning and overturning linkage 6223 is driven to rotate, the positioning and overturning rotating shaft 6221 is driven to swing about the positioning and overturning rotating shaft 6221, thereby enabling the welding piece positioning arm 61 to enter or exit the spot welding station 13.

When the square support ribs D are used for the aluminum formwork, the vertical fitting surface 611 is set as the alignment fitting surface during spot welding processing, so that the side surface of the square support rib D can be fitted with the alignment fitting surface. When the trapezoidal support rib D is used for the aluminum formwork, the inclined fitting surface 612 is set as the alignment fitting surface during spot welding processing, so that the trapezoidal support rib D can be fitted with the alignment fitting surface.

The lifting and overturning mechanism 1422 is connected with the lifting arm 1421, and the lifting arm 1421 is arranged between the conveying rollers of the feeding conveying mechanism 141. When the template main body A is conveyed on the conveying rollers of the feeding conveying mechanism 141, the lifting and overturning mechanism 1422 lowers the lifting arm 1421 below the conveying rollers of the feeding conveying mechanism 141. When the template main body A needs to be transferred from the feeding conveying mechanism 141 to the spot welding station 13, the lifting and overturning mechanism 1422 lifts the lifting arm 1421, and when the lifting arm 1421 contacts the bottom of the template main body A and tilts and lifts the template main body A, the template main body A slides into the spot welding station 13 after being tilted. In addition, in order to make the template main body A be lifted by the lifting arm 1421 and more easily slide into the spot welding station 13, the top surface of the lifting arm 1421 is provided with a plurality of balls or rollers, which are in rolling contact with the template main body A to reduce friction, so that the template main body A can slide into the spot welding station 13 after being slightly tilted and lifted.

One end of the lifting and overturning telescopic cylinder 14222 is connected to the feeding and discharging frame 16, and the other end is hingedly connected to the lifting and overturning linkage. When the piston rod of the lifting and overturning telescopic cylinder 14222 extends or retracts, the linkage drives the lifting and overturning rotating shaft 14221 to rotate, and the lifting and overturning rotating shaft 14221 drives the lifting arm 1421 to overturn up and down.
