Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and more specifically to a welding fixture for steel strip assemblies. Background Technology

[0002] A steel strip assembly is a collection of components consisting of a steel strip and several related parts. The steel strip is typically a long, thin strip of metal, made of materials such as carbon steel or stainless steel. In the assembly, the steel strip may be combined with other parts such as connectors, reinforcements, and supports through welding, riveting, or bolting to form a unified structure with a specific function. Steel strip assemblies are widely used in the automotive, construction, and electronics industries. When assembling the steel strip with components, welding is usually used for fixation. To ensure the stability of the steel strip during welding, a welding fixture is typically used to hold it in place before a welding robot is used for welding.

[0003] Existing steel strip assembly welding fixtures generally use bolts or clamps for fixing. For example, a portable fixture for welding thin-walled steel strips, with prior art publication number CN208374469U, uses an elbow clamp to stably and firmly hold the workpiece, and then uses resistance welding pliers for welding. This results in higher welding accuracy, adaptability to automated and semi-automated operations, higher efficiency, and avoidance of injury to personnel.

[0004] However, the existing technology has the following problems when used: traditional welding fixtures can only fix one steel strip assembly for welding, and the welding defects of the steel strip assembly cannot be automatically detected after welding, resulting in low welding efficiency of the steel strip assembly. Based on this, the present invention provides a steel strip assembly welding fixture with high welding efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a steel strip assembly welding fixture. This fixture supports two steel strip assemblies for welding through a central support mechanism and two side support mechanisms, thereby improving both welding efficiency and stability. Furthermore, two industrial cameras are used to photograph the two steel strip assemblies, automatically detecting the welded areas on the surface of the steel strip assemblies and confirming that the welding is defect-free, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel strip assembly welding fixture, including a base, on the top of which is fixedly provided a detachable central support mechanism and two side support mechanisms, with the central support mechanism located between the two side support mechanisms. The central support mechanism includes a central support seat, and each of the two side support mechanisms includes a side support seat A and two side support seats B, with side support seat A located between the two side support seats B. The side support seats A, side support seats B, and central support seat form two workstations for simultaneously placing two steel strip assemblies.

[0007] In a preferred embodiment, each side support A and each side support B is fixedly provided with a positioning pin to assist in positioning the steel strip assembly, thereby improving the placement accuracy of the steel strip assembly.

[0008] In a preferred embodiment, pneumatic clamps are fixedly provided on the top of the central support and on each side support B to improve the stability of the steel strip assembly.

[0009] In a preferred embodiment, the base is fixedly provided with multiple rollers, which are evenly distributed on the bottom of the base to facilitate adjustment of the position of the entire welding fixture.

[0010] In a preferred embodiment, a detachable control button is fixed on one side of the top of the base to facilitate the operation of the welding fixture by the staff.

[0011] In a preferred embodiment, the front end of the base is provided with a detachable safety component, which includes a vertical plate I and a vertical plate II. The vertical plate I is detachably fixed to the front end of the base, and the vertical plate II is fixed to the front end of the base by a linear module. A grating emitter is fixedly provided on the side of the vertical plate I near the vertical plate II, and a grating receiver is fixedly provided on the side of the vertical plate II near the vertical plate I. The grating emitter and the grating receiver can provide protection in front of the base to prevent accidental injury to workers.

[0012] In a preferred embodiment, a cylinder is fixedly provided at the rear end of the vertical plate II, a connecting plate is fixedly provided at the top end of the piston rod of the cylinder, and two detachable industrial cameras are fixedly provided at the bottom of the connecting plate. The industrial cameras can automatically detect the welding parts on the surface of the steel strip assembly to confirm that the welding of the steel strip assembly is free of defects.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a central support mechanism and two side support mechanisms to form two workstations to support the steel strip assembly for welding. This can improve the welding efficiency of the steel strip assembly, improve the stability of the steel strip assembly during welding, and thus improve the welding quality of the steel strip assembly. Furthermore, the use of multiple positioning pins to assist in positioning the steel strip assembly can further improve the stability of the steel strip assembly welding.

[0015] 2. The linear module drives two industrial cameras on the vertical plate II to take pictures of the two steel strip assemblies respectively, thereby automatically detecting the welding parts on the surface of the steel strip assembly and confirming that the welding of the steel strip assembly is free of defects. At the same time, the grating transmitter and grating receiver in front of the base play a protective role to prevent accidental injury to the workers, greatly improving the safety of the welding fixture.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Refer to the instruction manual appendix Figure 1-6 This utility model provides a steel strip assembly welding fixture, including a base 1. The top of the base 1 is fixedly provided with a detachable central support mechanism 2 and two side support mechanisms 3, and the central support mechanism 2 is located between the two side support mechanisms 3. The central support mechanism 2 includes a central support seat 201. Each of the two side support mechanisms 3 includes a side support seat A301 and two side support seats B302, and the side support seat A301 is located between the two side support seats B302. The side support seats A301, the side support seats B302 and the central support seat 201 form two workstations for simultaneously placing two steel strip assemblies.

[0028] Furthermore, a positioning pin 4 is fixedly provided on the top of each side support A301 and the top of each side support B302 to assist in positioning the steel strip assembly, thereby improving the placement accuracy of the steel strip assembly. A pneumatic clamp 5 is fixedly provided on the top of the central support 201 and each side support B302 to improve the stability of the steel strip assembly.

[0029] The base 1 is fixedly provided with multiple rollers 6 at the bottom, which are evenly distributed at the bottom of the base 1 to facilitate the adjustment of the position of the entire welding fixture. The base 1 is fixedly provided with a detachable control button 7 on one side of the top to facilitate the operation of the welding fixture by the staff.

[0030] In use, first check that the multiple pneumatic clamps 5 are in the open state. Then, place the two steel strip assemblies in the two workstations respectively. After inserting the multiple positioning pins 4 into the multiple positioning holes on the steel strip assemblies, press the control button 7 to start the multiple pneumatic clamps 5 to firmly press the steel strip assemblies. Then, the welding robot can be used to weld the two steel strip assemblies on the welding fixture. After welding is completed, first control the pneumatic clamps 5 to release them so that the product can be taken out. The steel strip assembly is supported by the middle support seat 201, the side support seat A301 and the side support seat B302, which can improve the stability of the steel strip assembly during welding and thus improve the welding quality of the steel strip assembly.

[0031] Refer to the instruction manual appendix Figure 1-3 and Figure 6The base 1 has a detachable safety component 8 at its front end. The safety component 8 includes a vertical plate I 801 and a vertical plate II 802. The vertical plate I 801 is detachably fixed to the front end of the base 1. The vertical plate II 802 is fixed to the front end of the base 1 through a linear module 803. A grating emitter 804 is fixedly provided on the side of the vertical plate I 801 near the vertical plate II 802. A grating receiver 805 is fixedly provided on the side of the vertical plate II 802 near the vertical plate I 801.

[0032] A cylinder 9 is fixedly mounted at the rear end of the vertical plate II802. A connecting plate 10 is fixedly mounted at the top of the piston rod of the cylinder 9. Two detachable industrial cameras 11 are fixedly mounted at the bottom of the connecting plate 10.

[0033] After the steel strip assembly welding is completed, the connecting plate 10 on the vertical plate II 802 is moved by the linear module 803. The two industrial cameras 11 at the bottom of the connecting plate 10 respectively capture images of the surfaces of the two steel strip assemblies, and the machine vision processing technology in the industrial cameras 11 is used to process the images. This allows for automatic detection of the welding parts on the surface of the steel strip assembly, confirming that the welding of the steel strip assembly is defect-free. At the same time, there are several infrared rays between the grating emitter 804 on the vertical plate I 801 and the grating receiver 805 on the vertical plate II 802. When the infrared rays are blocked and disconnected, the operator cannot use the control button 7 to start the pneumatic clamp 5, so as to avoid accidental injury to the operator. This improves the safety of the welding fixture.

[0034] In actual use, a control box can be installed on the base 1 to control the operation of the pneumatic clamp 5, cylinder 9, industrial camera 11, linear module 803, grating transmitter 804, and grating receiver 805 of this utility model. The control box contains a battery that provides power. All of the above technologies are existing and commonly used technologies, and will not be described in detail here.
