BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 The figure is a schematic structural diagram of a device for detecting misassembly of parts layers according to the present invention.
[0009] Figure 2 This is a top view of a device for detecting misassembly of parts layers according to the present invention.
[0010] In the figure: 1-frame; 2-cylinder; 3-claw; 4-displacement sensor; 5-folding frame; 6-locating pin; 7-first workpiece; 8-second workpiece; 9-positioning support frame. DETAILED DESCRIPTION
[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0012] See also Figure 1-2 The utility model provides a technical solution: a device for detecting the misassembly of the number of parts layers, comprising a frame 1, a cylinder 2 is provided on the frame 1, a clamping plate 3 is installed on the driving end of the cylinder 2, a displacement sensor 4 is installed on the cylinder 2, a folding frame 5 is provided on the frame 1 and on the right side of the clamping plate 3, a positioning pin 6 is provided on the folding frame 5, and the positioning pin 6 is used to support the first workpiece 7 and the second workpiece 8.
[0013] As a preferred technical solution, further, a positioning support frame 9 is provided on the frame body 1 and is located on the right side of the clamping plate 3 and on both sides of the folding frame 5.
[0014] As a preferred technical solution, further, the positioning support frame 9 is lower than the height of the positioning pin 6.
[0015] It should be noted that a wedge-shaped opening retaining plate 3 is designed at the front end of cylinder 2. Cylinder 2 extends until it encounters resistance from the workpiece. If the workpiece is a two-layer plate, the wedge-shaped opening will stop at a short extension stroke. Conversely, if the workpiece is a single-layer plate, the wedge-shaped opening will extend further when it is pressed against the plate. Using this principle, a displacement sensor 4 is added to detect the workpiece without interfering with the welding clamp. This check is added to the PLC program; if the distance is not met, the equipment will not automatically weld.
[0016] Process: 1. Cylinder extends → 2. Stops after hitting the workpiece → 3. Distance sensor detects cylinder extension distance → 4. Determines whether the workpiece is a single-layer or double-layer plate → 5. Feedback is sent to the PLC program to determine whether to proceed to the next automatic welding process.
[0017] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations. The phrase "includes an element defined by..." does not exclude the presence of other identical elements in the process, method, article, or device that includes the element.
[0018] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
