DETAILED DESCRIPTION

[0036] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0037] Combined here Figures 1 to 12 To describe a fully automatic assembly device for an air pump, specifically, the fully automatic assembly device for an air pump is constructed as an integrated structure, which has a supporting platform 1, an assembly platform 9, a film pressing mechanism 8 and a bracket mechanism 7. The film pressing mechanism 8 is used to simulate the installation and pressing of the connecting rod assembly and the U-shaped diaphragm of the pneumatic diaphragm pump. After the film pressing mechanism 8 presses the U-shaped diaphragm, the film pressing mechanism 8 can respectively perform a tightness test on the U-shaped diaphragms on both sides of the connecting rod assembly of the pneumatic diaphragm pump, and at the same time can smooth out wrinkles during transportation and loading and installation. This device can detect the tightness of the diaphragm after installation, thereby ensuring the installation quality of the U-shaped diaphragm.

[0038] Please refer to Figures 1 to 12 , a fully automatic assembly device for an air pump, comprising:

[0039] Assembly table 9, used to fix the connecting rod assembly of the pneumatic diaphragm pump;

[0040] The film pressing mechanism 8 is used to preliminarily press the U-shaped diaphragm and the connecting rod assembly of the pneumatic diaphragm pump together, and can also test the installation air tightness of the U-shaped diaphragm; and

[0041] The support mechanism 7 and the film pressing mechanism 8 are installed on the support mechanism 7; and

[0042] The supporting platform 1 has an automatic loader 13 installed on one end face of the supporting platform 1 through a mounting seat 5, a supporting plate 10 is installed on the supporting platform 1, and an automatic screw loading machine 11 and a diaphragm loader 14 are respectively installed on the supporting plate 10 through a fixing frame 12, the assembly platform 9 is installed on the supporting plate 10, and bracket mechanisms 7 are provided on both sides of the supporting platform 1.

[0043] The automatic loader 13 can be understood as a robot with a fixture mounted on its end effector. In the field of industrial assembly, a robot generally refers to a robotic arm equipped with a vision system. A robotic arm is a complex system with high precision, multiple inputs and outputs, high nonlinearity, and strong coupling. Due to its unique operational flexibility, it has been widely used in fields such as industrial assembly and safety and explosion protection. Preferably, the robotic arm can be a six-axis robotic arm, i.e., a robotic arm with six degrees of freedom. The six-degree-of-freedom robotic arm is a physical property testing instrument used in the field of mechanical engineering, with functions such as grasping and welding. During use, the connecting rod assembly is fixed to the assembly table 9 by the fixture of the automatic loader. After the diaphragm is installed, the liquid chamber, outlet connecting pipe, and inlet connecting pipe are loaded by the automatic loader.

[0044] Automatic screw-loading machine 11, also known as screw-locking robot or screw-locking robot arm, refers to a single-axis screw-locking mechanism mounted on a mechanical wall, which automatically completes screw-locking according to the set coordinates. The connecting rod assembly of the pneumatic diaphragm pump and the liquid chambers on both sides, as well as the liquid chambers and the outlet connecting pipe and the inlet connecting pipe are all fixed by bolts. The bolt connection between the connecting rod assembly of the pneumatic diaphragm pump and the liquid chambers on both sides, as well as the liquid chambers and the outlet connecting pipe and the inlet connecting pipe is completed by the automatic screw-loading machine, thereby improving the degree of automation of the device.

[0045] Diaphragm loader 14, the diaphragm loader can be understood as a robot with an adsorption component on its end effector. The adsorption component can be a micro negative pressure pump equipped with a suction cup, also called a micro vacuum pump. The micro negative pressure pump is a micro air pump that can generate negative pressure, including an air intake nozzle and an air outlet nozzle. It can continuously form negative pressure at the air intake nozzle. When in use, the suction cup is connected to the air intake nozzle of the micro negative pressure pump to achieve the adsorption function of the diaphragm. Of course, the adsorption component can also be a negative pressure suction cup. The negative pressure suction cup is a device that uses the change in air pressure inside the suction cup to adsorb objects. The negative pressure suction cup has a large adsorption force and high precision. When working, it is Diaphragms need to be installed at both ends of the connecting rod assembly of the pneumatic diaphragm pump, and the raised sides of the diaphragms on both sides must face the same direction, that is, after installation, the raised end of the diaphragm on one side faces the inner side of the connecting rod assembly. During installation, the adsorption component of the diaphragm loader 14 can be used to adsorb the inner concave part of the diaphragm to complete the installation, while the raised end of the diaphragm on the other side faces the outer side of the connecting rod assembly. During installation, the adsorption component of the diaphragm loader 14 can be used to adsorb the side end of the outer convex part of the diaphragm, and then cooperate with the pressing ring 818 on the film pressing mechanism 8 to complete the pressing installation of the diaphragm. The pressing ring 818 can prevent the raised end of the diaphragm facing the outside of the connecting rod assembly from falling due to the influence of gravity during the installation process.

[0046] For this application, the connecting rod assembly of the pneumatic diaphragm pump is fixed on the assembly table 9, and the connecting rod assembly of the pneumatic diaphragm pump and the U-shaped diaphragm are pressed together by the film pressing mechanism 8. After the film pressing mechanism 8 presses the U-shaped diaphragm, if the raised portion of the U-shaped diaphragm faces the drainage fan 86, the motor 1 83 drives the drainage fan 86 to rotate and blow air to the air outlet 82. Since the side wall of the film pressing mechanism 8 is sealed as a whole, a negative pressure is caused at the drainage duct 81. If the airtightness after installation is good, the raised portion of the U-shaped diaphragm is Due to the pressure difference on both sides, the surface of the U-shaped diaphragm will bulge smoothly under the action of the pressure difference, and at the same time, the wrinkles during transportation and loading and installation can be smoothed out. If the concave part of the U-shaped diaphragm is facing the drainage fan 86, the drainage fan 86 is driven by the motor 83 to rotate and blow air toward the concave part of the U-shaped diaphragm. If the airtightness after installation is good, the surface of the U-shaped diaphragm will bulge smoothly under the wind force of the drainage fan 86. This device can detect the airtightness of the diaphragm after installation, thereby ensuring the installation quality of the U-shaped diaphragm.

[0047] As shown in Figures 8 to 11 of this embodiment, the film pressing mechanism 8 includes a drainage air duct 81, and a plurality of fixing frames 84 are fixedly connected to the edge of the end surface of one side of the drainage air duct 81 at equal intervals. The gaps between the plurality of fixing frames 84 constitute an air outlet 82. One end of the fixing frame 84 is fixedly connected to the end surface of the drainage air duct 81, and the other ends of the plurality of fixing frames 84 are fixedly connected to a fixing plate 85. A motor 1 83 is fixedly connected to the end surface of the fixing plate 85 on one side close to the drainage air duct 81. The housing of the motor 1 83 is fixedly connected to the fixing plate 85. The driving end of the motor 1 83 is fixedly connected to a drainage fan 86. A connecting ring 87 is fixedly connected to the end surface of the other edge of the drainage air duct 81. Fixed convex plates 88 are fixedly connected to both sides of the end surface of the connecting ring 87 away from the drainage air duct 81. A pressing cylinder 89 is fixedly connected to the fixed convex plate 88. The bottom surface of the outer shell of the cylinder 89 is fixedly connected to the fixed convex plate 88, and the driving end of the pressing cylinder 89 is fixedly connected to the pressing telescopic rod 810, and the pressing telescopic rod 810 is fixedly connected to the adapter 812, and the adapter 812 is fixedly connected to the connecting convex plate 813. The connecting convex plate 813 is fixedly connected to a pressing link 814 at one end close to the central axis of the connecting ring 87, and the connecting ring 87 is fixedly connected to the pressing part outer shell 811. The pressing link 814 and the pressing cylinder 89 are both arranged on the inner side of the pressing part outer shell 811, and the pressing link 814 is fixedly connected to the end face of the side away from the drainage air duct 81, and the pressing ring 818 is sleeved on the inner side of the pressing part outer shell 811. The connection between the pressing ring 818 and the pressing part outer shell 811 is provided with a sealed rubber ring 1 816, and a sealed rubber ring 2 817 is sleeved and fixedly connected to the outside of the pressing ring 818.

[0048] In this embodiment, the compression ring 818 and the compression part shell 811 are sealed and sleeved together by a sealed rubber ring 816. Specifically, the outer side of the sealed rubber ring 816 is fixedly connected to the inner side of the compression part shell 811, and the inner ring of the sealed rubber ring 816 is sealed and sleeved together with the outer side of the compression ring 818 through an oil seal. While ensuring the overall sealing of the side wall of the compression film mechanism 8, the mobility of the compression ring 818 is also ensured. When in use, after the connecting rod assembly of the pneumatic diaphragm pump is fixed on the assembly table 9, the U-shaped After the diaphragm is loaded, the driving end of the pressing cylinder 89 can drive the pressing telescopic rod 810 to extend, and the extension of the telescopic rod 810 drives the pressing link 814 to push outward, thereby driving the pressing ring 818 to press the U-shaped diaphragm and the diaphragm hoop on the connecting rod assembly of the pneumatic diaphragm pump. In addition, the adapter 812 and the connecting convex plate 813 can be detachably connected, such as by a bolt thread connection between the adapter 812 and the connecting convex plate 813, so that it is easy to replace the pressing link 814 and the pressing ring 818 of different sizes, so as to adjust the pressure of different diaphragms. The connecting rod assembly of the pneumatic diaphragm pump of the size is pressed together with the diaphragm to improve the versatility of the device. At the same time, the corresponding sealing rubber ring 816 can also be replaced to ensure the overall sealing of the side wall of the film pressing mechanism 8. In particular, after the film pressing mechanism 8 presses the U-shaped diaphragm, if the raised part of the U-shaped diaphragm faces the drainage fan 86, the motor 83 drives the drainage fan 86 to rotate and blow air at the air outlet 82. Since the side wall of the film pressing mechanism 8 is sealed as a whole, negative pressure is caused at the drainage air duct 81. If the sealing is good after installation, the U-shaped Due to the pressure difference on both sides of the raised part of the diaphragm, the surface of the U-shaped diaphragm will bulge smoothly under the action of the pressure difference, and at the same time, the wrinkles during transportation and loading and installation can be smoothed out. If the concave part of the U-shaped diaphragm is facing the drainage fan 86, the drainage fan 86 is driven by the motor 83 to rotate and blow air toward the concave part of the U-shaped diaphragm. If the airtightness after installation is good, the surface of the U-shaped diaphragm will bulge smoothly under the wind force of the drainage fan 86. This device can detect the airtightness of the diaphragm after installation, thereby ensuring the installation quality of the U-shaped diaphragm.

One end of the assembly frame 92 is fixedly connected to the connecting plate 91, and the other end of the assembly frame 92 is fixedly connected to the assembly frame 2 93.

A connecting rod 1 916 is fixedly connected to the opening of the through slot 1 96. The connecting rod 1 916 is arranged on the end face of the assembly plate 95 on the same side as the assembly frame 2 93. One end of the connecting rod 1 916 is fixedly connected to the end face of the assembly plate 95, and the other end of the connecting rod 1 916 is fixedly connected to the fixed base plate 915. The end face of the fixed base plate 915 close to the assembly plate 95 is fixedly connected to the cylinder 2 9 17. The driving end of the cylinder 2 917 is fixedly connected to the telescopic rod 2 918, and the telescopic rod 2 918 is fixedly connected to the fixing frame 919. The mounting frame 94 is fixedly connected to the cylinder 1 98 through the fixing ring 99. The driving end of the cylinder 1 98 is fixedly connected to the telescopic rod 1 911.

Preferably, the pin shaft for connecting the adapter 1 913 and the fixed arc plate 914 can be an elastic pin shaft. The elastic pin shaft is a special pin shaft that realizes connection or separation through an elastic pin, which has the function of damping and buffering. When in use, the protective ring 922 is first installed on the mounting plate 920 through the mounting column 924. When the film pressing mechanism 8 presses the connecting rod assembly, the exhaust valve on the connecting rod assembly of the pneumatic diaphragm pump is passed through the protective rubber ring 923 and placed between the fixed arc plates 914 by the automatic loader 13 to prevent The protective rubber ring 923 on the guard ring 922 can offset the lateral force of the film pressing mechanism 8 during pressing, thereby protecting the connection between the exhaust valve and the connecting rod assembly. By pushing the fixed arc plate 914 through the cylinder 1 98 to fix the exhaust valve, the connecting rod assembly of the pneumatic diaphragm pump can be fixed on the assembly table 9, which is convenient for the film pressing work of the film pressing mechanism 8. When the connecting rod assembly of the pneumatic diaphragm pump and the liquid chambers on both sides and the liquid chambers and the outlet connecting pipe and the inlet connecting pipe are bolted together, the cylinder 2 917 can drive the connecting rod assembly of the pneumatic diaphragm pump to rise as a whole by lifting the fixing frame 919, so as to facilitate the automatic screw machine 11 and the automatic loader 13 to perform assembly work.

[0051] As shown in Figure 7 of this embodiment, the support plate 10 includes a support plate body 101, a motor 2 105 is embedded in and fixedly connected to the support plate body 101, a fixing ring 102 is provided on the outside of the motor 2 105, the fixing ring 102 is fixedly connected to the support plate body 101, the driving end of the motor 2 105 is coaxially fixedly connected to the limiting member 106 through the connecting shaft, the limiting member 106 is coaxially fixedly connected to the adapter 2 107 through the connecting shaft, the adapter 2 107 is fixedly connected to the connecting plate 91, and the fixing ring 102 is fixedly connected to the limiting member 106. It is connected to a fixed vertical plate 103, and a clamping plate 104 is fixedly connected to the end face of one side of the fixed vertical plate 103. The clamping plate 104 is clamped with a limit member 106. In this embodiment, the limit member 106 is a square limit frame with smooth transitions on all sides, and the clamping plate 104 is a limit clamping plate with a U-shaped cross-section. When working, under the restriction of the clamping plate 104 and the limit member 106, the motor 2 105 can drive the assembly table 9 to rotate 90 degrees, thereby facilitating the adjustment of the position and orientation of the connecting rod assembly of the pneumatic diaphragm pump on the assembly table 9, ensuring the smooth progress of the assembly work.

[0052] As shown in Figure 12 of this embodiment, the bracket mechanism 7 includes a cylinder fixing plate 71, and a sliding rod cylinder 2 72 is fixedly connected to the end surface of one side of the cylinder fixing plate 71. The driving end of the sliding rod cylinder 2 72 is fixedly connected to the outer shell of the drainage air duct 81, and the two sides of the end surface of the other side of the cylinder fixing plate 71 are respectively fixedly connected to a hydraulic cylinder 1 73 and a hydraulic rod 2 75. The driving end of the hydraulic cylinder 1 73 is fixedly connected to a mechanism telescopic rod 1 78, and the lower end of the mechanism telescopic rod 1 78 is fixedly connected to a support plate 1 74, and the support plate 1 74 is fixedly connected to the supporting platform 1, and the driving end of the hydraulic rod 2 75 is fixedly connected to a mechanism telescopic rod 2 79, and the lower end of the mechanism telescopic rod 2 79 is fixedly connected to a support column 76, and the lower end of the support column 76 is fixedly connected to a support plate 2 77. In this embodiment, in order to facilitate the operation of this device, when the bracket mechanism 7 is installed, the assembly table 9 is in a position as shown in FIG. Figure 1 When it is on the far right side as shown, it is necessary to ensure that the center axis of the pressing ring 818 of the film pressing mechanism 8 on the bracket mechanism 7 is in the same vertical plane as the center axis of the assembly plate 95. When in use, the sliding rod cylinder 2 72 can drive the film pressing mechanism 8 to slide along the length direction of the sliding rod cylinder 2 72, thereby changing the relative position of the film pressing mechanism 8 and the connecting rod assembly of the pneumatic diaphragm pump, thereby facilitating the diaphragm assembly work of the film pressing mechanism 8. The hydraulic cylinder 1 73 drives the mechanism telescopic rod 1 78 to retract and the hydraulic rod 2 75 drives the mechanism telescopic rod 2 79 to retract, thereby changing the vertical relative position of the connecting rod assembly of the film pressing mechanism 8 and the pneumatic diaphragm pump, facilitating the alignment of the connecting rod assembly of the film pressing mechanism 8 and the pneumatic diaphragm pump. At the same time, after replacing the connecting rod assembly of the pneumatic diaphragm pump of different models, adjusting the bracket mechanism 7 can realize the alignment of the connecting rod assembly of the film pressing mechanism 8 and the pneumatic diaphragm pump, thereby improving the versatility of the device.

[0053] As shown in Figures 1 and 2 of this embodiment, a slide rail 3 is fixedly connected to the upper end surface of the support platform 1, and a pulley 4 is slidably connected to the slide rail 3. The pulley 4 is fixedly connected to the bottom surface of the support plate body 101 of the support plate 10, and a slide cylinder 6 is fixedly connected to the side end surface of the support platform 1. The driving end of the slide cylinder 6 is fixedly connected to the side end surface of the support plate body 101 of the support plate 10. During operation, the slide cylinder 6 can drive the support plate 10 and the assembly platform 9 to move left and right on the support platform 1, thereby facilitating the automatic screw machine 11, the automatic loader 13 and the diaphragm loader 14 to assemble the various components of the pneumatic diaphragm pump on the assembly platform 9.

[0054] When working, there are the following steps:

[0055] By starting the slide cylinder 6, the assembly table 9 is transported to the Figure 1 As shown on the left side, the connecting rod assembly of the pneumatic diaphragm pump is placed on the assembly table 9 by the automatic loader 13 .

[0056] The exhaust valve of the connecting rod assembly is fixed by pushing the fixed arc plate 914 through the cylinder 98 of the assembly platform 9, so that the connecting rod assembly of the pneumatic diaphragm pump can be fixed on the assembly platform 9.

[0057] Start the slide cylinder 16 to transport the assembly table 9 to the Figure 1 On the far right side shown, the telescopic rod 1 78 of the hydraulic cylinder 1 73 drives the telescopic rod 1 and the telescopic rod 2 79 of the hydraulic rod 2 75 drives the telescopic rod 2, thereby changing the vertical relative position of the film pressing mechanism 8 and the connecting rod assembly of the pneumatic diaphragm pump, and aligning the pressing ring 818 of the film pressing mechanism 8 with the diaphragm hoop of the connecting rod assembly of the pneumatic diaphragm pump.

[0058] The diaphragm loader 14 installs the U-shaped diaphragms at both ends of the connecting rod assembly of the pneumatic diaphragm pump. When installing the diaphragm with the protruding end facing the inner side of the connecting rod assembly, the adsorption component of the diaphragm loader 14 adsorbs the inner concave part of the diaphragm to complete the pre-installation, and then the U-shaped diaphragm and the diaphragm hoop on the connecting rod assembly of the pneumatic diaphragm pump are pressed together by the pressing ring 818 of the film pressing mechanism 8.

[0059] When installing the diaphragm with the protruding end facing the outside of the connecting rod assembly, the adsorption component of the diaphragm loader 14 adsorbs the side end of the convex part of the diaphragm, and then the slide cylinder 2 72 of the bracket mechanism 7 drives the film pressing mechanism 8 to approach and cover the outer part of the diaphragm. The adsorption component of the diaphragm loader 14 releases the adsorption on the side end of the convex part of the diaphragm, and the pressing ring 818 on the film pressing mechanism 8 continues to complete the pressing installation of the diaphragm.

[0060] By adjusting the slide cylinder 2 72 of the bracket mechanism 7, the film pressing mechanism 8 is moved away from the connecting rod assembly of the pneumatic diaphragm pump, and the automatic screw machine 11 threadedly connects the connecting rod of the connecting rod assembly with the U-shaped diaphragm. In particular, the bolt can be a self-tapping screw with a sealing gasket A2 fixed to the bottom surface of the nut A1 as shown in Figure 13, thereby improving the airtightness and stability of the connection between the diaphragm and the connecting rod.

[0061] During installation, two automatic screwing machines 11 can be used to simultaneously install screws on the diaphragms on both sides, thereby offsetting the lateral force during installation.

[0062] By adjusting the slide cylinder 2 72 of the bracket mechanism 7 again, the film pressing mechanism 8 is made to approach the connecting rod assembly of the pneumatic diaphragm pump again, and the diaphragm is pressed again by the film pressing mechanism 8, so as to test the airtightness of the installed diaphragm. If the concave portion of the U-shaped diaphragm is facing the drainage fan 86, the drainage fan 86 is driven by the motor 1 83 to rotate and blow air toward the concave portion of the U-shaped diaphragm. If the airtightness after installation is good, the surface of the U-shaped diaphragm will bulge smoothly under the action of the wind force of the drainage fan 86.

[0063] If the raised portion of the U-shaped diaphragm faces the induced draft fan 86, the motor 83 drives the induced draft fan 86 to rotate and blow air toward the air outlet 82. Since the side wall of the film pressing mechanism 8 is sealed as a whole, negative pressure is caused in the induced draft duct 81. If the airtightness after installation is good, the raised portion of the U-shaped diaphragm will bulge smoothly due to the pressure difference on both sides, and the surface of the U-shaped diaphragm will bulge under the action of the pressure difference.

[0064] Once again, the assembly table 9 is transported to the position as shown in FIG. Figure 1 As shown on the left side, the liquid chamber is loaded by an automatic loader, and then the connecting rod assembly of the pneumatic diaphragm pump and the liquid chambers on both sides are pre-fixed by the automatic loader, and then the bolt connection between the connecting rod assembly of the pneumatic diaphragm pump and the liquid chambers on both sides is completed by an automatic screw loading machine.

[0065] The outlet connecting pipe and the inlet connecting pipe are loaded by an automatic loading machine, and then the liquid chamber is pre-fixed with the outlet connecting pipe and the inlet connecting pipe by the automatic loading machine, and then the bolt connection between the liquid chamber and the outlet connecting pipe and the inlet connecting pipe is completed by an automatic screw loading machine.

[0066] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the spirit of the present invention.
