[0029] See also Figure 1-Figure 6 The utility model provides an assembly tool with a mixing error prevention function, comprising a cylinder, a guide rail, a pressure head 1 fixedly mounted on the telescopic end of the cylinder, a support platform 2, a bracket 3 and a base 4 for mounting the guide rail, wherein the bracket 3 is fixedly mounted on the support platform 2, the support platform 2 is fixedly mounted on the base 4, a detection component is installed on the side of the pressure head 1, and the side of the pressure head 1 is fixedly mounted on the slider of the guide rail;

[0030] The detection component includes an angular sensor 5, a proximity sensor 6 and a positioning member 7, and a PLC controller 8 installed on the side of the support platform 2. The proximity sensor 6 and the angular sensor 5 are both fixedly installed on the pressure head 1. The proximity sensor 6 and the angular sensor 5 are both connected to the PLC controller 8 by signal, and the positioning member 7 is installed on the pressure head 1.

[0031] It should be noted that a support seat 22 for fixing a workpiece is fixedly mounted on the support platform 2 .

[0032] By adopting the above scheme and using the detection component, when the bushing and the workpiece are press-fitted, after the positioning member 7 contacts the bushing, the angular sensor 5 determines whether there is a bushing by detecting the position of the positioning member 7. At the same time, the information of whether the bushing is detected by the proximity sensor is transmitted to the PLC controller. When the bushing information is normal, the PLC controller issues an instruction to the cylinder to press-fit; otherwise, press-fitting is not allowed. Compared with manual judgment, it can effectively improve work efficiency and effectively reduce the labor intensity of workers.

[0033] In one embodiment of the utility model, a support rod 9 is fixedly installed on the support platform 2, and two support rods 9 are provided. A first photoelectric sensor 10 is fixedly installed on the side of the two support rods 9. The first photoelectric sensor 10 is connected to the PLC controller 8 by signal, and the two support rods 9 are symmetrically arranged relative to the center line of the support platform 2.

[0034] By adopting the above scheme, through the use of the first photoelectric sensor 10, before the left or right part is press-fitted, if the left part needs to be press-fitted, the first photoelectric sensor 10 on the left side detects whether there is a QR code on the side of the workpiece. If it is detected, the PLC controller 8 controls the cylinder to press-fit. If not detected, the PLC controller 8 does not allow the cylinder to press-fit. The first photoelectric sensor 10 first detects whether there is a workpiece and then press-fits it. This can effectively improve the accuracy of press-fitting, reduce the error rate, effectively improve the quality of press-fitting, and realize automated press-fitting.

[0035] In one embodiment of the utility model, the positioning member 7 includes a movable rod 11 and a boss 12, and a through hole 13 opened in the pressure head 1, the boss 12 can be slidably installed in the through hole 13, and a limiting platform 14 is arranged in the through hole 13, the upper part of the limiting platform 14 is in contact with the bottom of the boss 12, the upper part of the movable rod 11 can be detected by the detection part of the angular sensor 5, and the upper surface of the limiting platform 14 and the bottom surface of the boss 12 are located in the same horizontal plane.

[0036] In one embodiment of the utility model, a lubrication mechanism 15 is further included, and the lubrication mechanism 15 is used to lubricate the bushing. The lubrication mechanism 15 includes a lubrication box 16 and a sponge pad 17. The sponge pad 17 is placed in the lubrication box 16. A second photoelectric sensor 18 is fixedly installed on the box wall of the lubrication box 16. The second photoelectric sensor 18 is connected to the PLC controller 8 by signal.

[0037] The operator on the support table 2 clamps the bushing and puts it into the lubrication box 16. After the second photoelectric sensor 18 detects the operator's action of lubricating the bushing, it transmits a signal to the PLC controller 8, and the PLC controller 8 allows the cylinder to drive the bushing to be pressed together with the workpiece;

[0038] The second photoelectric sensor 18 does not detect the operator's action of lubricating the bushing, and the PLC controller 8 does not allow the cylinder to drive the bushing to be pressed onto the workpiece.

[0039] By adopting the above scheme, through the use of the second photoelectric sensor 18, it is possible to detect whether the bushing is lubricated, which can reduce the occurrence of operational omissions in the process and effectively improve the quality of automatic press-fitting.

[0040] In an embodiment of the present utility model, a protective shell 21 is fixedly mounted on the pressure head 1 , and the protective shell 21 is used to protect the diagonal sensor 5 and the proximity sensor 6 .

[0041] By adopting the above solution and using the protective shell 21, it is possible to effectively prevent the diagonal sensor 5 and the proximity sensor 6 from colliding when installing the control arm.

[0042] Working principle: When the bushing and the workpiece are pressed together, after the positioning member 7 contacts the bushing, the angular sensor 5 determines whether the bushing exists by detecting the position of the positioning member 7. At the same time, the information of whether the bushing is detected by the proximity sensor is transmitted to the PLC controller. When the bushing information is normal, the PLC controller issues an instruction to the cylinder to press-fit; otherwise, press-fitting is not allowed. Compared with manual judgment, it can effectively improve work efficiency and effectively reduce the labor intensity of workers.

[0043] Before the left or right part is press-fitted, if the left part needs to be press-fitted, the first photoelectric sensor 10 on the left side detects whether there is a QR code on the side of the workpiece. If it is detected, the PLC controller 8 controls the cylinder to press-fit. If it is not detected, the PLC controller 8 does not allow the cylinder to press-fit. The first photoelectric sensor 10 first detects whether there is a workpiece and then press-fits, which can effectively improve the accuracy of press-fitting, reduce the error rate, and effectively improve the quality of press-fitting, so as to realize automatic press-fitting.

[0044] The operator on the support table 2 clamps the bushing and puts it into the lubrication box 16. After the second photoelectric sensor 18 detects the operator's action of lubricating the bushing, it transmits a signal to the PLC controller 8, and the PLC controller 8 allows the cylinder to drive the bushing to be pressed together with the workpiece;

[0045] The second photoelectric sensor 18 does not detect the operator's action of lubricating the bushing, and the PLC controller 8 does not allow the cylinder to drive the bushing and the workpiece to be pressed together. It can detect whether the bushing is lubricated or not, which can reduce the occurrence of operational omissions in the process and effectively improve the quality of automatic pressing.
