[0034] Please refer to Figure 1-13 As shown, an embodiment of the present invention provides a component loading device for component production and assembly. This device can be arranged on the component production and assembly conveyor line and is used to load and install components onto the installation positions on the components.

[0035] The following content takes the application of this component loading device on the conveyor line 1000 to load and install the support cap 1300 on the housing 1100 of the compressor as an example to specifically describe this component loading device.

[0036] This component loading device includes a component buffer table 100, a loading mechanism 200, a first lifting mechanism 300, and a clamping mechanism 400. The component buffer table 100 is fixed on the support table 500 and is arranged at the storage station on one side of the conveyor line 1000; the loading mechanism 200 is installed on the support table 500 through the first support frame 510 and is arranged at the loading station of the conveyor line 1000; the first lifting mechanism 300 is installed on the support table 500 and is located below the loading mechanism 200; the clamping mechanism 400 is installed on both sides of the line body of the conveyor line 1000.

[0037] The working principle of this device is as follows: First, store the support caps 1300 required for one-time loading on the component buffer table 100. The first lifting mechanism 300 jacks up the housing 1100 conveyed to the loading station on the conveyor line. Then, the clamping mechanism 400 clamps and positions the jacked-up housing 1100. The loading mechanism 200 grabs all the support caps 1300 on the component buffer table 100 at one time and loads and installs them onto the housing 1100 jacked up by the first lifting mechanism 300. This device can accurately load the components into the installation positions on the components at one time, thereby avoiding problems such as misloading and missing loading and improving production efficiency.

[0038] As Figure 6As shown, in this embodiment, the part buffer table 100 includes a mounting table 120, a turntable 130, and a servo motor 140. The turntable 130 is rotatably mounted on the mounting table 120. The part storage portion 110 is provided on the turntable 130. The number of part storage portions 110 is the same as the number of support caps 1300 to be installed on the chassis 1100, and the distribution positions of the part storage portions 110 on the turntable 130 correspond to the installation positions of the support caps 1300. Since three support caps 1300 need to be loaded and installed at one time in this example, and the mounting holes on the chassis for installing the support caps 1300 are arranged in a circumferential array, therefore, the number of part storage portions 110 is also three, and the part storage portions 110 are also arranged in a circumferential array in the circumferential direction of the turntable 130. There is a feed inlet 121 on the mounting table 120. The servo motor 140 is fixed to the mounting table 120 and its output shaft is connected to the turntable 130 to drive the turntable 130 to rotate so that each part storage portion 110 takes turns to feed at the feed inlet 121. During operation, the part buffer table 100 can store all the support caps 1300 required for one-time feeding before each feeding by placing the support caps 1300 on the part storage portions 110 one by one, and making the support caps 1300 distributed according to the preset positions, which can ensure the accurate installation position and quantity of parts when the feeding mechanism 200 feeds in the subsequent feeding process.

[0039] In some embodiments, a cleaning and receiving tray 150 is further fixed to one side of the mounting table 120. After the device stops working, if there are still support caps 1300 stored in the part storage portions 110 of the turntable 130, the support caps 1300 can be taken out and placed in the cleaning and receiving tray 150, so as to avoid the problem of stockpiling errors in the next work.

[0040] Refer to Figure 7-8 , for the part buffer table 100, the device is also provided with a vibrating loading tray 600 and a feeding guide rail 700 located at the stockpiling station, and automatic stockpiling can be realized through the vibrating loading tray 600 and the feeding guide rail 700. Specifically, the discharge end of the vibrating loading tray 600 is docked with the feed inlet 121 of the part buffer table 100 through the feeding guide rail 700. A pushing cylinder 710 is provided at the feeding end of the feeding guide rail 700 for pushing the parts into the feed inlet 121 of the part buffer table 100. During operation, the required support caps 1300 are manually poured into the vibrating loading tray 600. The vibrating loading tray 600 sends the support caps 1300 to the end of the feeding guide rail 700 to wait through vibration and rotation. After being grabbed by the part feeding mechanism 200 on the part buffer table 100, the parts can be pushed into the part storage portion 110 one by one from the feed inlet 121 through the pushing cylinder 710 to complete a new stockpiling process.

[0041] Such as Figure 9-10As shown, in this embodiment, the loading mechanism 200 of the device includes a horizontal slide module 210, a vertical lifting mechanism 220 and an end clamp 230. The horizontal slide module 210 and the vertical lifting mechanism 220 can drive the end clamp 230 to move in the horizontal direction and the vertical direction. The end clamp 230 can grab all the parts on the part cache table 100 at one time for loading.

[0042] Specifically, the horizontal slide module 210 includes a linear guide rail 211 and a slide 212. The slide 212 is installed on the linear guide rail 211 and can slide in the horizontal direction. The slide 212 is also installed on the first support frame 510 through the slide rail and the slider. The vertical lifting mechanism 220 includes an electric push rod 221, a linear slide rod 222 and a fixture mounting plate 223. The fixture mounting plate 223 is installed on the slide 212 through the linear slide rod 222 and the linear bearing 224 and can slide in the vertical direction. The electric push rod 221 is vertically fixed on the slide 212, and the bottom end of the electric push rod 221 is fixedly connected to the fixture mounting plate 223.

[0043] The end clamp 230 includes a clamping jaw assembly installed on the clamp mounting plate 223. The number and position distribution of the clamping jaw assembly should also meet the requirement of completing part loading at one time, that is, the number of the clamping jaw assembly is the same as the number of the support caps 1300 required to be installed on the housing 1100, and the distribution position corresponds to the installation position of the support caps 1300. Each clamping jaw assembly includes a press cylinder 231, a press rod 233 and a material pickup barrel clamp 232. The material pickup barrel clamp 232 is vertically fixed to the lower end of the mounting plate. The material pickup barrel clamp 232 has an elastic clip. The press rod 233 is located in the center hole of the material pickup barrel clamp 232. The press cylinder 231 is vertically fixed to the mounting plate and one end of its piston rod is connected to the press rod 233. When taking materials, the end clamp 230 descends on the part cache table 100, so that the support cap 1300 is pressed into the center hole of the material taking barrel clamp 232, and the support cap 1300 opens the elastic clip, and the elastic clip clamps the support cap 1300. The end clamp 230 rises to remove the support cap 1300 on the part cache table 100; when discharging materials, the pressing cylinder 231 drives the pressing rod 233 to press down, and the support cap 1300 is pushed out from the lower end of the material taking barrel clamp 232, so that the support cap 1300 is pressed into the mounting hole of the casing 1100, and the loading assembly is completed.

[0044] Reference Figure 11, in this embodiment, the first lifting mechanism 300 of the device includes a first support plate 310 and a first lifting cylinder 320. The first support plate 310 is slidably mounted on the support table 500 through a vertical slide bar 330. One end of the piston rod of the first lifting cylinder 320 is connected to the first support plate 310 to drive the first support plate 310 to move up and down. The first support plate 310 is used to dock with the positioning tooling 1200 of the machine housing 1100. When the first lifting mechanism 300 is working, when the conveyor line 1000 conveys the positioning tooling 1200 with the machine housing 1100 to the loading station, the first lifting cylinder 320 drives the first support plate 310 to move upward. The first support plate 310 can lift the positioning tooling 1200 and the machine housing 1100 on the conveyor line 1000 together for the loading mechanism 200 to load. After the loading is completed, the first lifting cylinder 320 drives the first support plate 310 to descend and reset, and puts the machine housing 1100 and its positioning tooling 1200 back on the conveyor line 1000 again.

[0045] As Figure 12 shown, in this embodiment, the clamping mechanism 400 of the device includes two clamping plate assemblies. Each clamping plate assembly includes a cylinder mounting plate 410, a clamping cylinder 420, and a profiling clamping plate 430. The clamping cylinder 420 is horizontally fixed on the cylinder mounting plate 410. The profiling clamping plate 430 is fixed to one end of the piston rod of the clamping cylinder 420. The two clamping plate assemblies are respectively arranged on both sides of the first lifting mechanism 300, and the profiling clamping plates 430 of the two clamping plate assemblies are opposite in position. The cylinder mounting plates 410 of the two clamping plate assemblies are respectively fixed on both sides of the line body of the conveyor line. During loading, after the first lifting mechanism 300 lifts the machine housing 1100, the clamping cylinder 420 of the clamping mechanism 400 can push the profiling clamping plate 430 to clamp and position the machine housing 1100, which can prevent the components from moving during the loading of the loading mechanism 200 and ensure the position accuracy of the part installation.

[0046] As Figure 4 and Figure 13 shown, in some embodiments, the loading device further includes a detection device 800 and a second lifting mechanism 900 arranged at the detection station of the conveyor line. The detection device 800 is fixed on the support table 500 through a second support frame 520 and is located directly above the second lifting mechanism 900. The second lifting mechanism 900 is used to lift the components on the conveyor line for the detection device 800 to detect. The detection device 800 is used to detect whether parts are installed at the installation positions on the components.

[0047] Specifically, the second lifting mechanism 900 has the same structure as the first lifting mechanism 300. The second lifting mechanism 900 includes a second support plate 910 and a second lifting cylinder 920. The second support plate 910 is slidably mounted on the support table 500 through a vertical slide rod 930. One end of the piston rod of the second lifting cylinder 920 is connected to the second support plate 910 to drive the second support plate 910 to move up and down. The second lifting mechanism 900 can lift the housing 1100 and its positioning tooling 1200 conveyed to the detection station for the detection device 800 to perform detection.

[0048] The detection device 800 specifically includes a displacement sensor 810 and a probe rod assembly. The number of the probe rod assemblies is also the same as the number of the support caps 1300 on the housing 1100 and the positions are also corresponding to the installation positions of the support caps 1300. Each probe rod assembly includes a detection cylinder 810 and a detection guide rod 820. The detection cylinder 810 is vertically and fixedly mounted on the second support frame 520, and the detection guide rod 820 is vertically fixed at the bottom end of the piston rod of the detection cylinder 810. The displacement sensor 810 is fixed between the detection guide rods 820 of each probe rod assembly through a connecting plate 840.

[0049] The detection principle of the detection device 800 is as follows: during detection, the detection cylinder 810 drives the detection guide rod 820 and the displacement sensor 810 to move downward. When the detection guide rod 820 presses against the support cap 1300, it stops moving downward. The displacement sensor 810 sends a detection signal to the controller. At this time, the value detected by the displacement sensor 810 is within the preset value range, indicating that the support cap 1300 has been loaded and installed on the housing 1100; when the support cap 1300 is missing on the housing 1100, during the detection process, the descending stroke of the detection guide rod 820 is larger, and at this time the value detected by the displacement sensor 810 will exceed the preset value range. The controller can issue an alarm according to this detection result. Therefore, through this detection device 800, the part feeding error occurring during the component assembly production process can be further avoided.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
