Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle oil tank production and processing, in particular to an automatic marking device for motorcycle metal oil tanks after they have passed inspection. Background Art

[0002] The general production process of motorcycle metal fuel tanks is as follows: cutting - stamping - welding - welding inspection - sealing test - painting - painting inspection - assembly (removing painting plugs and installing fuel tank accessories) - inspection - finished product. It can be seen that the semi-finished product needs to be inspected for appearance before painting, that is, welding inspection, and a sealing test is also required. The sealing test is a must-check item for each fuel tank before leaving the factory, and the test method usually adopts the "water inspection method" or "water tank method". Because it needs to be immersed in water, the sealing test process is generally set before painting. After painting, it is usually necessary to conduct a coating quality appearance inspection, and after assembly, it is also necessary to conduct an inspection. After passing the inspection, a qualified mark is required. At the current technical level, the sealing test, assembly and inspection are basically operated manually, and are manually marked according to the process requirements. It can be seen from this that the current process has the disadvantages of high labor costs and large site occupation (involving multiple transfers).

[0003] The applicant proposed an improvement, using a differential pressure air leak detector to test the oil tank for tightness, and moving the process to after assembly. The new process adopts a semi-automatic method for the tightness test. The oil tank is placed on the tooling base, and the differential pressure air leak detector is used through the air pipe 1. Figure 1 As shown, it is connected to a special cock 2, and is connected to the oil tank to be tested (not shown) through its oil port (the oil tank only has two small openings, the oil port and the oil pump outlet pipe port). After pressing the start button, the electronic control system controls the differential pressure air leak detector to automatically complete the sealing test of the oil tank to be tested. Based on this background, the applicant plans to develop an automatic identification device.

[0004] The qualified fuel tank mark is used for internal quality management and control in the factory to avoid missing or mislabeling, provide qualified product identification for subsequent delivery or assembly, and prevent the misuse of unqualified products. The qualified mark is usually located in an invisible position when the fuel tank is normally installed. It is required to be eye-catching in color, not easy to erase, and not cause damage to the coating. At the same time, it is required to be economical, efficient, stable and reliable. There are many marking methods available for reference in China, such as stickers, inkjet coding, laser, etc., but none of them are ideal. Utility Model Content

[0005] The utility model aims to provide an automatic marking device for a motorcycle metal oil tank.

[0006] The purpose of the utility model is achieved through the following technical solutions: an automatic marking device for a motorcycle metal fuel tank, comprising a control system, a linear drive mechanism, a marking pen and an air source;

[0007] The marking pen is installed on the linear drive mechanism. The marking pen is a pneumatic marking pen. The air pressure is provided by an air source connected to the marking pen. The marking pen has a push-type pen tip. When pushed, the pen tip retreats into the pen cavity to flow out ink for marking. After the push is released, the pen tip automatically returns to its original position to seal the ink in the pen cavity. The control system is connected to the linear drive mechanism and the air source.

[0008] The marking pen is installed near the tooling base for placing the oil tank at the sealing test station. The control system is associated with the differential pressure air leak detector at the sealing test station through an electronic control system so as to form a linkage with the sealing test. After the differential pressure air leak detector control system sends a test pass signal, the automatic marking device of the utility model automatically starts according to the program to complete the marking operation.

[0009] The linear drive mechanism may be a slide cylinder, a linear module, etc.

[0010] Beneficial effects:

[0011] 1) The automatic marking device of the utility model can not only form a mark that meets the requirements, but also has a simple structure, is stable and reliable, can ensure smooth marking, and can basically use up the ink each time, which can reduce the marking cost;

[0012] 2) After the oil tank of the utility model passes the sealing test, it is automatically marked without human intervention, avoiding missing labels, wrong labels and misuse, etc.; it completely eliminates manpower consumption and realizes automation, providing a technical basis for optimizing the oil tank production process.

[0015] Figure 4 The figure is a schematic diagram of the working principle of the preferred embodiment of the utility model. DETAILED DESCRIPTION

[0016] like Figure 2 , 3 As shown, the motorcycle metal fuel tank automatic identification device of this embodiment is arranged on the far side of the tooling base for placing the fuel tank at the sealing test station, specifically in the gap between two seat plates 12 supported by the bracket 11 and arranged side by side on the left and right of the tooling base.

[0017] The automatic marking device mainly includes a control system, a linear drive mechanism, a marking pen and an air source.

[0018] like Figure 2 , 3 As shown in Figure 4, the marking pen 21 is fixed on the sliding cylinder 22 as a linear drive mechanism. The control system controls the forward and backward movement of the sliding cylinder 22 through the electromagnetic valve 23, adjusts the thrust force of the marking pen 21 through the pressure regulating valve 24, and controls the thrust speed through the throttle valve 26. The marking pen 21 is modified from a pneumatic marking pen, that is, the pressure is directly applied by compressed air instead of by pressing the pressurized pen. Figure 3 As shown, the air source is connected to the rear end of the marking pen 21 through a pressure regulating valve 25, thereby controlling the ink flow of the marking pen 21.

[0019] The automatic marking device of this embodiment is intended to form a linkage with the differential pressure air leak detector at the sealing test station through the electronic control system, so as to receive the oil tank sealing test pass instruction from the differential pressure air leak detector, and then automatically start the sliding cylinder 22, so that the pen tip of the marking pen 21 moves forward and acts on the oil tank and retreats into the pen cavity under the action of the top thrust, and under the action of compressed air, the ink flows out to form a mark at the specified position of the oil tank; after the marking is completed, the sliding cylinder 22 retreats to the starting position, and the pen tip of the marking pen 21 is reset to seal the ink in the pen cavity.

[0020] The utility model automatic marking device can not only form a mark that meets the requirements, but also has a simple structure, is stable and reliable, can ensure smooth marking, and can basically use up the ink each time. In addition, it has low power consumption and good economy. The utility model automatic marking device does not require manual intervention and realizes automation, providing a good technical foundation for the optimization of fuel tank production process and technological progress.
