Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator back panel molding lines, in particular to a pressure resistance detection device for automatic assembly of refrigerator back panel molding lines. Background Art

[0002] The refrigerator molding process essentially involves using an automated production line to precisely assemble the components after they are manufactured, according to design requirements. The assembly line automatically completes operations such as docking, installation, fixing, and wiring components, greatly improving assembly efficiency and accuracy.

[0003] Similarly, after assembly is completed, the entire refrigerator needs to be tested and inspected, and compression testing is an important part of this. However, existing compression testing is generally independent of the assembly line. After the refrigerator back panel is formed, there are many internal sheet metal, hinges and other parts, which is not conducive to the start of testing. Therefore, we propose a compression testing device that can perform compression testing in the early stage of back panel forming to solve the above problem. Utility Model Content

The utility model proposes a pressure resistance detection device for automatic assembly of a refrigerator back panel forming line, which can perform real-time pressure resistance detection on the refrigerator back panel in the refrigerator forming line.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a pressure resistance detection device for the automatic assembly of the refrigerator back panel forming line, comprising: a base frame, a height frame placed on the top surface of the base frame, a detection component fixed at the center of the height frame and a clamping component located on the top surface of the base frame. A detection platform is also provided at the center of the top of the base frame, and the bottom of the detection platform is connected to the base frame through a sliding feeding track. The clamping component includes three groups and is wrapped around the detection platform, which is used to pneumatically press each back panel surface of each refrigerator. A groove is concave in the center of the detection platform and multiple groups of pressure sensor blocks are protruding at the center of the groove. The top surface of the pressure sensor block is flush with the top surface of the detection platform and is in extrusion contact with the bottom surface of the refrigerator back panel. The detection component is used to vertically press down the bottom surface of the refrigerator back panel.

[0006] Furthermore, the detection assembly includes a downward pressure cylinder, a guide rod, a support platform and a pressure platform. The four corners of the support platform are fixed to the top surface of the base frame by fixing rods. The guide rods include at least two and are arranged through the support platform. The two ends of the pressure platform are slidably connected to the guide rods. The downward pressure cylinder is inverted and fixed on the top of the support platform, and the output end is arranged through the support platform. The center of the back of the pressure platform is connected and fixed to the output end of the downward pressure cylinder through a fixed coupling.

[0007] Furthermore, the feeding track is a double-slide rail type, and the detection platform is also fixed with a push handle on the side corresponding to the feeding track. A slider is fixed at the bottom of the detection platform and is slidably connected to the feeding track through the slider.

[0008] Furthermore, the base frame is also provided with a positioning cylinder at the top corresponding to the detection table. The positioning cylinder is vertically fixed to the base frame and the output end is arranged through the base frame. A ball table is also fixed at the output end of the positioning cylinder, and the ball table is embedded in the center of the back of the detection table.

[0009] Furthermore, each of the clamping components includes a pushing cylinder and a clamping plate. The two sides of the pushing cylinder are horizontally fixed to the base frame through a T-shaped stage, and its output end is connected and fixed to the clamping plate. The clamping plate has a variety of sizes and corresponds one-to-one to different back panels of the refrigerator.

[0010] Furthermore, a matching platform is vertically fixed to the center of the chassis on both sides of the corresponding detection platform, and the top surface of the matching platform is flush with the top surface of the detection platform.

[0011] Furthermore, the pressure sensing blocks include at least three groups and are equidistantly arranged on the inner bottom of the groove.

[0012] Compared with the existing technology, the beneficial effects of the utility model include: the initially formed refrigerator back panel can be clamped and positioned by three groups of ring-arranged pushing cylinders, and the surface stress of the back panel is detected in real time by the staggered and equidistantly spaced pressure sensing blocks, and then compared. If the pressure difference at different locations does not exceed the threshold, the back panel passes the pressure resistance test. The overall structure is novel and reliable, and can be adapted for use with the refrigerator forming line. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0018] According to one embodiment of the present invention, Figure 1-Figure 2 Shown.

[0019] As for the overall structure, a pressure resistance detection device for the automated assembly of the refrigerator back panel molding line includes: a base frame 1, a height frame 2 placed on the top surface of the base frame 1, a detection component 3 fixed to the center of the height frame 2, and a clamping component 4 located on the top surface of the base frame 1. A detection platform 5 is also provided at the top center of the base frame 1. The bottom of the detection platform 5 is connected to the base frame 1 by a sliding feed track 21. The clamping component 4 includes three groups and is arranged around the detection platform 5. It is used to pneumatically press each back panel surface of each refrigerator. The center of the detection platform 5 has a recessed groove 6 and a plurality of groups of pressure sensing blocks 7 protrude from the center of the groove 6. The top surface of the pressure sensing block 7 is flush with the top surface of the detection platform 5 and is in compression contact with the bottom surface of the refrigerator back panel. The detection component 3 is used to vertically press down the bottom surface of the refrigerator back panel. In this embodiment, the pressure sensing blocks 7 include at least three groups and are equidistantly arranged at the bottom of the groove 6.

[0020] In this embodiment, the detection component 3 includes a downward pressure cylinder 8, a guide rod 9, a support platform 10 and a pressing platform 11. The four corners of the support platform 10 are fixed to the top surface of the base frame 1 by fixing rods 12. The guide rods 9 include at least two and are arranged through the support platform 10. The two ends of the pressing platform 11 are slidingly connected to the guide rods 9. The downward pressure cylinder 8 is inverted and fixed on the top of the support platform 10, and the output end is arranged through the support platform 10. The back center of the pressing platform 11 is connected and fixed to the output end of the downward pressure cylinder 8 through a fixed coupling 13.

[0021] Furthermore, the feed track 21 is a double-slide rail type, and the inspection platform 5 is also fixed with a push handle 14 on the side corresponding to the track direction of the feed track 21. A slider 15 is fixed to the bottom of the inspection platform 5 and is slidably connected to the feed track via the slider 15. The base frame 1 is also provided with a positioning cylinder 16 at the top corresponding to the inspection platform 5. The positioning cylinder 16 is vertically fixed to the base frame 1 and the output end is arranged through the base frame 1. The output end of the positioning cylinder 16 is also fixed with a ball table 17, which is embedded and engaged with the center of the back of the inspection platform 5.

[0022] Each clamping assembly 4 includes a push cylinder 18 and a clamping plate 19. The push cylinder 18 is horizontally fixed to the base frame 1 via T-shaped platforms 22 on both sides, and its output end is connected and fixed to the clamping plate 19. The clamping plates 19 come in a variety of sizes and correspond to different back panels of the refrigerator. A mating platform 20 is also vertically fixed to the center of the base frame on both sides of the corresponding testing platform 5. The top surface of the mating platform 20 is flush with the top surface of the testing platform 5.

[0023] Through the above structure, in response to the pressure resistance test of the back panel in the refrigerator forming line, the operator first pushes the test table 5 to slide on the track through the feeding track 21 and the handrail to send it to the corresponding test position. After sliding to the center of the base frame 1, the positioning cylinder 16 at the bottom of the base frame 1 detects and outputs, and the ball table 17 is embedded in the bottom center of the test table 5 to realize the positioning of the test table 5. Then the clamping assembly 4 surrounded on three sides operates, and the clamping cylinder outputs linearly, driving the clamping plate 19 to press the outer side of the refrigerator. The design of different models of clamping plates 19 is to ensure the rational dislocation of places such as wire openings and faults.

[0024] After the three sides are clamped and stabilized, the pressing platform 11 is pressed down vertically by the top downward pressure cylinder 8, and the bottom surface of the pressing platform 11 contacts and squeezes the inner bottom of the refrigerator molding back panel to ensure that the back of the back panel contacts the three groups of pressure sensing blocks 7 in the groove 6 of the detection platform 5. The three groups of staggered and equidistant pressure sensing blocks 7 detect the real-time back panel surface stress through the built-in pressure sensor, and then compare them. If the pressure difference at different places does not exceed the threshold, the back panel compressive test is qualified. Applying this detection device to the refrigerator molding line can greatly simplify the subsequent process detection process of the refrigerator and avoid the inconvenience of stress detection after the refrigerator is assembled.

[0025] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
