Description

Technical Field

[0001] The present invention relates to the automotive field, and in particular to a flushness detection device combining air suction and magnetic suction. Background Art

[0002] In the body side panel welding production line of the automobile manufacturing plant, the inner and outer panel assemblies of the side panel are welded on the fixture. During the welding process of the side panel outer panel, in order to facilitate the operation of the production personnel, the side panel outer panel assembly is placed flat on the fixture for welding. The premise of welding is that the sheet metal parts are well positioned and there is no obvious surface difference between the outer panel parts. The surface difference of the side panel outer panel refers to the gaps and surface unevenness that often occur between the components of the side panel outer panel during the assembly process. These issues need to be considered in the welding process to ensure the position and quality of the welding during the side panel outer panel welding process, as well as to ensure the surface difference of the side panel after welding.

[0003] The existing solution only uses the original multiple suction cup groups to absorb the sheet metal. This method often results in insufficient suction force, which causes insufficient positioning and clamping of the sheet metal parts, resulting in uneven surfaces and surface differences. In addition, the number of suction cups is relatively large and a single suction cup is prone to failure. Summary of the invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a flushness detection device combining air suction and magnetic suction, which uses a customized pneumatic suction cup and an electromagnet to position and tighten the components of the side panel outer panel. At the same time, a flushness detection device is added to detect the flushness data online, thereby avoiding the problem of excessive flushness of the side panel.

[0005] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solution:

[0006] The present invention provides a flushness detection device combining air suction and magnetic suction, comprising a flushness detection module, a magnetic suction module, an air suction module, and a fixture substrate;

[0007] The flushness detection module comprises a side enclosure front section flushness detection device and a side enclosure rear section flushness detection device, which are used to detect flushness information of the side enclosure front section and the side enclosure rear section respectively, and transmit the flushness information to the PLC system;

[0008] The magnetic attraction module is used for magnetically adsorbing the side outer panel, and includes an electromagnet body, an electromagnet limit box, and an electromagnet interface;

[0009] The air suction module comprises a side panel front section outer panel suction cup and a side panel rear section outer panel suction cup, which are used to suck the side panel outer panel tightly with the air-controlled suction cup;

[0010] The fixture base plate is used to fix the fixture.

[0011] Preferably, it also includes a side panel front section outer panel ejector pin and a side panel rear section outer panel ejector pin.

[0012] Preferably, an indicator light is also included, and the indicator light is used to emit light according to a preset indication strategy.

[0013] Preferably, the preset indication strategy is: being in the first indication state by default, and being in the second indication state when a signal indicating that the flushness detection is unqualified is identified.

[0014] Preferably, the surface of the electromagnet body can completely fit with the surface of the workpiece through contour design.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention combines an air-controlled suction cup with an electric-controlled magnet to achieve the advantages of long distance, large suction force, long duration, and high fit. At the same time, it is equipped with a real-time flushness detection device to achieve 100% real-time feedback of flushness, effectively eliminating the subsequent flushness repair workload and improving the whole line operation rate.

[0034] Example

[0035] This embodiment provides a flushness detection device combining air suction and magnetic suction, such as Figure 1 As shown, it includes a flush detection module, a magnetic suction module, an air suction module, and a fixture substrate. As for the design of the flush detection module, it includes a side panel front section flush detection device 1 and a side panel rear section flush detection device 10, which are respectively used to detect the flush information of the side panel front section and the side panel rear section, and transmit the flush information to the PLC system. The PLC system will judge and feedback whether the flush information is qualified according to the preset rules. As for the design of the air suction module, it includes a side panel front section outer panel suction cup 4 and a side panel rear section outer panel suction cup 6, which are used to suck the side panel outer panel tightly with an air-controlled suction cup. The fixture substrate 5 is used to fix the fixture.

[0036] As for the design of the magnetic attraction module, it is used for magnetically adsorbing the side outer panel, and includes an electromagnet body 8, an electromagnet limit box 3, and an electromagnet interface 7, wherein the electromagnet body 8 is used to provide magnetic attraction when powered on, the electromagnet limit box 3 is used to accommodate the electromagnet and play a limiting role, and the electromagnet interface 7 is used to receive external signals and electrical energy. Preferably, the surface of the electromagnet body 8 can be completely fitted with the surface of the workpiece through a profiling design, so as to ensure the surface difference between the workpieces.

[0037] Preferably, the air suction combined with magnetic suction flushness detection device provided in this embodiment also includes a side panel front section outer panel ejector pin 2 and a side panel rear section outer panel ejector pin 9, which are used to assist in positioning and supporting during the side panel welding process to ensure the stability of the processing process.

[0038] Preferably, the flush difference detection device of air suction combined with magnetic suction provided in this embodiment further comprises an indicator light, which is used to emit light according to a preset indication strategy. Specifically, the preset indication strategy may be: the first indication state is in default, and the second indication state is in place when a signal indicating that the flush difference detection is unqualified is identified. For example, the indicator light is always green, but when a signal indicating that the flush difference detection is unqualified is identified, the indicator light will emit red light to the outside. At this time, the staff can obtain information about the unqualified flush difference by observing the color change of the indicator light, and thus take timely treatment measures, such as stopping welding.

[0039] The timing principle of this embodiment is described as follows: Figure 2 As shown. On the side panel welding production line, the operator places the front and rear sections of the side panel outer panel on the work station fixture respectively, manually presses the start button, the fixture is clamped, the suction cup module sucks the sheet metal, the magnetic module sucks the front and rear sections together, the sensor of the flushness detection module detects and feeds back real-time data to the PLC (programmable logic controller) system, the flushness is qualified, the green light of the indicator light is always on, and welding can be started to weld the front and rear sections of the side panel outer panel into one. If the flushness exceeds the tolerance, the indicator light will flash red, and the whistle can be sounded to stop welding. First check the specific cause of the side panel flushness exceeding the tolerance and deal with it.

[0040] In this embodiment, the suction distance of the suction cup of the air suction module is large, but the suction force is relatively small and can be maintained for a short time; the magnetic distance of the electromagnet of the magnetic suction module is small, but the magnetic force generated is large and lasts for a long time. Therefore, by combining the air-controlled suction cup with the electric-controlled magnet, the two suction methods cooperate with each other, while meeting the advantages of long distance, large suction force, long duration, and high fit. At the same time, it is equipped with a real-time detection device for face difference, which realizes 100% real-time feedback of face difference and out-of-tolerance alarm and error prevention, effectively eliminating the subsequent face difference rework workload and improving the start-up rate of the entire line.

[0041] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention.
