The most common air pumps today are made of stainless steel, primarily due to its strong oxidation resistance, long service life, resistance to rust and corrosion, resistance to deformation, lead-free safety, high hardness, and wear resistance. These advantages make it durable and widely used in various balls, bicycles, motorcycles, and more.

[0040] See also Figures 1 to 9The present invention discloses an automatic detection mechanism 100 for an air pump cylinder. The automatic detection mechanism 100 includes a frame 110, a feed module 120, a welding tension detection module 130, an outlet pressure detection module 140, and a no-load tension detection module 150. The feed module 120 is mounted on the frame 110 and is used for loading and transporting the air pump. The welding tension detection module 130, the outlet pressure detection module 140, and the no-load tension detection module 150 are all disposed on the top side of the feed module 120. Specifically, the automatic detection mechanism 100 also includes a control panel 160. The welding tension detection module 130, the outlet pressure detection module 140, and the no-load tension detection module 150 are electrically connected to the control panel 160, so that the detection data of the welding tension detection module 130, the outlet pressure detection module 140, and the no-load tension detection module 150 are transmitted to the control panel 160 for analysis and judgment, and the detection results are obtained. As several air pumps are transported through the feeding module 120, the welding tension detection module 130 detects the welding tension of the air pump caps to determine whether the welding firmness of the air pump caps meets the preset standard. The outlet pressure detection module 140 detects the outlet air pressure of the air pumps to determine whether the outlet air pressure of the air pumps meets the preset standard. The no-load tension detection module 150 detects the tension of the air pumps when no-load to determine whether the tension of the air pumps when no-load meets the preset standard. During the production and processing of one-way air pumps, the finished air pumps must undergo multiple performance tests to determine whether the finished air pumps meet the shipping standards. Among them, including the welding strength test of the air pump cover, the air pressure test of the air pump, and the air pump tension test when the air pump is no-load, in the traditional performance test of the air pump product 200, the enterprise needs to set up three corresponding performance test equipment to test the product. Based on this, the enterprise also needs to equip at least three operators to operate the equipment, which results in low product testing efficiency and waste of manpower and workshop work space. The air pump automatic detection mechanism 100 of the present invention integrates the welding tension detection module 130, the air pressure detection module 140 and the no-load tension detection module 150. In the process of the feeding module 120 feeding the air pump product 200, the welding tension detection module 130, the air pressure detection module 140 and the no-load tension detection module 150 can complete the three corresponding performance tests of the air pump product 200, thereby greatly improving the performance test efficiency of the product, while effectively reducing labor costs and saving workshop work space, thereby specifically solving the technical problems existing in the existing air pump performance testing equipment.

[0041] Further, the feeding module 120 comprises a material supporting disc 121, a plurality of bottom molds 122, and a divider 123. The divider 123 is installed on the top side surface of the rack 110, and the output end of the divider 123 is arranged away from the rack 110. The geometric center of the material supporting disc is connected to the output end of the divider 123, so that the divider 123 can control the rotation of the material supporting disc for feeding. The plurality of bottom molds 122 are arranged on the top side surface of the material supporting disc 121, and the plurality of bottom molds 122 are arranged at equal angles radially with the geometric center of the material supporting disc 121 as the axis. Specifically, the welding tension detection module 130, the air pressure detection module 140, and the idle tension detection module 150 are respectively arranged at preset workstations on the top side of the plurality of bottom molds 122. When the inflator products 200 are subjected to performance detection, the plurality of inflator products 200 are respectively fed to the plurality of bottom molds 122. The divider 123 drives the material supporting disc 121 to rotate intermittently for feeding. The rotation frequency of the material supporting disc 121 is matched with the detection cycle of the inflator products 200, so that each bottom mold 122 can be sequentially and accurately transferred to the detection workstations of the welding tension detection module 130, the air pressure detection module 140, and the idle tension detection module 150, and respectively stay at the detection workstations for a preset detection cycle, so that the inflator products 200 on each bottom mold 122 can sequentially complete welding tension detection, air pressure detection, and idle tension detection.

[0042] Specifically, each bottom mold 122 comprises a fixed mold 1221, a movable mold 1222, and a mold sliding rail 1223. The mold sliding rail 1223 is arranged on the top side surface of the material supporting disc 121 along the radial direction of the corresponding bottom mold 122. The fixed mold 1221 is arranged at the end of the radial direction of the mold sliding rail 1223. The movable mold 1222 is slidingly connected to the mold sliding rail 1223. The fixed mold 1221 and the movable mold 1222 cooperate to form a mounting workstation for supporting and mounting the inflator products 200. When the inflator products 200 are subjected to performance detection by the inflator automatic detection mechanism 100, the inflator products 200 are sequentially fed to the plurality of bottom molds 122. One end of the inflator is matched with the fixed mold 1221, and the other end of the inflator is matched with the movable mold 1222. During this process, the movable mold 1222 can be slid to the corresponding matching point along the mold sliding rail 1223 according to the different initial lengths of the inflators, so as to adapt to the initial length of the inflator. Specifically, each bottom mold 122 further comprises a silica gel sheet group 1224, which is respectively arranged on the top side surface of the movable mold 1222 and the top side surface of the fixed mold 1221. When the inflator products 200 are fed to the corresponding bottom molds 122, the two ends of the inflator products 200 are respectively mounted to the silica gel sheet group 1224 on the top side surface of the movable mold 1222 and the fixed mold 1221, so that the silica gel sheet group 1224 can avoid direct contact between the inflator and the movable mold 1222 and the fixed mold 1221, thereby preventing the inflator products 200 from being scratched during the detection process.

[0043] Further, the welding tension detection module 130 comprises a first fixed cylinder 131, a first movable cylinder 132, a first tension sensor 133, a first tension cylinder 134 and a first photoelectric switch 135. When the bottom die 122 moves to the detection station corresponding to the welding tension detection module 130, the first fixed cylinder 131 is correspondingly matched with the fixed die 1221 and connected to the rack 110; the first movable cylinder 132 is correspondingly matched with the movable die 1222 and slidably connected to the rack 110 along the extension direction of the die slide rail 1223; the first tension cylinder 134 is connected to the rack 110, and the output shaft of the first tension cylinder 134 is arranged along the extension direction of the die slide rail 1223; one end of the first tension sensor 133 is connected to the output shaft of the first tension cylinder 134, the other end of the first tension sensor 133 is connected to the side surface of the first movable cylinder 132, and the first tension sensor 133 is electrically connected to the control panel 160; the first photoelectric switch 135 is arranged at one end of the top side of the fixed die 1221. Specifically, the cylinder bottom cover 220 of the inflator product 200 is sleeved on one end of the inflator body 210 and connected by welding, the output shafts of the first fixed cylinder 131 and the first movable cylinder 132 are both connected with the pressing block 101. When the first photoelectric switch 135 detects that the inflator product 200 is installed on the top side of the bottom die 122, the first fixed cylinder 131 drives the pressing block 101 to press the one end of the body 210 of the inflator product 200 through the corresponding fixed die 1221, and the first movable cylinder 132 drives the pressing block 101 to press the one end of the cylinder bottom cover 220 of the inflator product 200 through the corresponding movable die 1222; at this time, the output shaft of the first tension cylinder 134 pulls the first tension sensor 133 and the first movable cylinder 132, so as to pull the cylinder bottom cover 220 of the inflator product 200 through the corresponding movable die 1222, and further to give the cylinder bottom cover 220 of the inflator product 200 a movement trend towards the one end of the body 210, so as to detect the welding strength between the cylinder bottom cover 220 and the body 210 of the inflator product 200. With the increase of the output power of the first tension cylinder 134, the stress of the welding point between the cylinder bottom cover 220 and the body of the inflator product 200 increases synchronously; when the tension of the first tension cylinder 134 rises to a set value, the welding point of the inflator product 200 does not break, and the welding strength of the inflator product 200 meets the standard; when the tension of the first tension cylinder 134 does not reach the set value, but the welding point of the inflator product 200 breaks at this time, the tension parameter detected by the first tension sensor 133 begins to decrease, so that the detected tension value is less than the set value, and the control panel 160 issues an alarm at this time.

[0044] Further, the no-load tension detection module 150 comprises a second fixed cylinder 151, a second movable cylinder 152, a second tension sensor 153, a second tension cylinder 154, and a second photoelectric switch 155. When the bottom die 122 moves to the detection station corresponding to the no-load tension detection module 150, the second fixed cylinder 151 is correspondingly matched with the fixed die 1221 and connected to the rack 110; the second movable cylinder 152 is correspondingly matched with the movable die 1222 and slidably connected to the rack 110 along the extension direction of the die slide rail 1223; the second tension cylinder 154 is connected to the top side surface of the corresponding fixed die 1221, and the output shaft of the second tension cylinder 154 is arranged along the extension direction of the die slide rail 1223; one end of the second tension sensor 153 is connected to the output shaft of the second tension cylinder 154, and the other end of the second tension sensor 153 is connected to the top side surface of the corresponding movable die 1222, and the second tension sensor 153 is electrically connected to the control panel 160; the second photoelectric switch 155 is arranged at one end of the top side of the corresponding fixed die 1221. Specifically, the main body 210 of the inflator product 200 comprises an inner tube 211 and an outer tube 212, one end of the inner tube 211 is connected to the cylinder bottom cover 220, the other end of the inner tube 211 is slidably sleeved in the inner tube 212, and the no-load tension detection module 150 is used for detecting the tension range when the inner tube 211 and the outer tube 212 are pulled and pressed. The output shaft of the second fixed cylinder 151 and the output shaft of the second movable cylinder 152 are both connected with the pressing block 101. When the second photoelectric switch 155 detects that the bottom die 122 is installed with the inflator product 200 on the top side surface, the second fixed cylinder 151 drives the pressing block 101 to press the outer tube 212 of the inflator product 200 tightly with the corresponding fixed die 1221, and the second movable cylinder 152 drives the pressing block 101 to press the cylinder bottom cover 220 of the inflator product 200 tightly with the corresponding movable die 1222, that is, the inner tube 211; at this time, the output shaft of the second tension cylinder 154 drives the second tension sensor 153 and the corresponding movable die 1222, thereby driving the inner tube 211 of the inflator product 200 to reciprocate relative to the outer tube 212, so as to detect the tension required for pulling and pressing the inner tube 211 and the outer tube 212 of the inflator product 200 when the inflator product 200 is in no-load state. When the detected tension value is not within the set parameter range, the control panel 160 issues an alarm.

[0045] Furthermore, the air outlet pressure detection module 140 includes a third fixed cylinder 141, a third photoelectric switch 142, a fourth fixed cylinder 143 and an air pressure sensor 144. When a bottom mold 122 moves to the detection station corresponding to the air outlet pressure detection module 140, the third fixed cylinder 141 corresponds to the fixed mold 1221 and is connected to the frame 110; the third photoelectric switch 142 is arranged on the top side of the corresponding movable mold 1222; the fourth fixed cylinder 143 is correspondingly arranged at the end of the air outlet pipe 213 of the air pump product 200, and the output shaft of the fourth fixed cylinder 143 is connected to the air pressure sensor 144, and the fourth fixed cylinder 143 can drive the air pressure sensor 144 to closely cooperate with the end of the air outlet pipe 213 of the air pump product 200; the air pressure sensor 144 is electrically connected to the control panel 160. Specifically, the output shaft of the third fixed cylinder 141 is connected to the pressure block 101. When the third photoelectric switch 142 detects that the air pump product 200 is installed on the top surface of the bottom mold 122, the third fixed cylinder 141 drives the pressure block 101 to cooperate with the corresponding fixed mold 1221 to press the outer tube 212 of the air pump product 200. The fourth fixed cylinder 143 drives the air pressure sensor 144 to cooperate closely with the end of the air outlet pipe 213. The outlet pressure detection module 140 is further provided with a fifth fixed cylinder 145 at one end corresponding to the movable mold 1222. The fifth fixed cylinder 145 is provided at the bottom surface of the bottom mold 122. The air cylinder 145 is connected to the frame 110. The output shaft of the fifth fixed air cylinder 145 is connected to a first drive arm 1451. The first drive arm 1451 is located at the end of the corresponding movable mold 1222 facing away from the corresponding fixed mold 1221. The fifth fixed air cylinder 145 drives the movable mold 1222 to slide toward the corresponding fixed mold 1221 via the first drive arm 1451, thereby compressing the inner tube 211 of the air pump product 200 relative to the outer tube 212. At this time, a pressure sensor detects the outlet pressure at the end of the outlet pipe 213. If the detected pressure value is outside the set parameter range, the control panel 160 issues an alarm.

[0046] Furthermore, the fifth fixed cylinder 145 is also provided with a second drive arm 1452. The second drive arm 1452 is connected to the other end of the output shaft of the fifth fixed cylinder 145 relative to the first drive arm 1451. In addition, the second drive arm 1452 and the detection station of the outlet air pressure detection module 140 are respectively provided on the other side of the material support tray 121. Specifically, when a bottom mold 122 moves to the bottom side of the second drive arm 1452, the fifth fixed cylinder 145 can drive the second drive arm 1452 to push the corresponding movable mold 1222 to move along the mold slide 1223, thereby adjusting the movable mold 1222 to a preset position, thereby enabling the movable mold 1222 to cooperate with the corresponding fixed mold 1221 to support the air pump product 200. Specifically, each bottom mold 122 also includes a limiting magnetic block 1225, which is respectively provided on one side of the mold slide 1223. Before the air pump product 200 is loaded onto the corresponding bottom mold 122, the fifth fixed cylinder 145 drives the second driving arm 1452 to move along the corresponding mold slide rail 1223, thereby driving the movable mold 1222 to slide along the mold slide rail 1223. At this time, the corresponding limiting magnetic block 1225 attracts the movable mold 1222, thereby limiting the movable mold 1222 to a preset position.

[0047] Furthermore, the automatic detection mechanism 100 of the air pump also includes a blanking module 170, which corresponds to a plurality of bottom molds 122 and is arranged on the top side of a preset workstation on the top surface of the material support tray 121 and is connected to the frame 110, and the blanking module 170 is arranged at the feeding terminal of the feeding module 120. Specifically, the unloading module 170 includes a rodless cylinder 171, a third movable cylinder 172, a vacuum suction cup 173 and a fourth photoelectric switch 174. When a bottom mold 122 supports the air pump product 200 after completing all inspection processes and moves to the preset workstation corresponding to the unloading module 170, the rodless cylinder 171 is arranged along the extension direction of the corresponding mold slide rail 1223 and connected to the frame 110, the third movable cylinder 172 is connected to the output end of the rodless cylinder 171, and the output end of the third movable cylinder 172 is connected to the vacuum suction cup 173. The vacuum suction cup 173 is correspondingly arranged on the top side of the air pump product 200, and the fourth photoelectric switch 174 is correspondingly arranged on the top side of one end of the movable mold 1222. When the fourth photoelectric switch 174 senses the pump product 200 on the corresponding bottom mold 122, the rodless cylinder 171 drives the third movable cylinder 172 to move to the top side of the pump product 200, and the third movable cylinder 172 drives the vacuum suction cup 173 to descend, so that the vacuum suction cup 173 is correspondingly connected to the side surface of the pump product 200. At this time, the vacuum suction cup 173 absorbs the pump product 200; then, the third movable cylinder 172 drives the vacuum suction cup 173 to rise, thereby driving the pump product 200 to separate from the corresponding bottom mold 122, and then, the rodless cylinder 171 drives the third movable cylinder 172 to drive the pump product 200 to separate from the feeding module 120, and at this time, the vacuum suction cup 173 is closed to complete the unloading.

[0048] Furthermore, the automatic air pump inspection mechanism 100 further includes a conveyor belt 180, which is correspondingly arranged on the bottom side of the rodless cylinder 171 at the end facing away from the feeding module 120. Specifically, when the unloading module 170 unloads the air pump product 200 that has completed the inspection process, the rodless cylinder 171 drives the third movable cylinder 172 to move the air pump product 200 to the top side of the conveyor belt 180. At this time, the vacuum suction cup 173 is closed, and the air pump product 200 falls to the top surface of the conveyor belt 180, thereby carrying out the subsequent transportation of the air pump product 200.

[0049] Furthermore, the control panel 160 uses a touch screen as an input panel to complete the human-computer interaction of the air pump automatic detection mechanism 100 .

[0050] In summary, the automatic detection mechanism for the air pump disclosed in the present invention adopts a welding tension detection module to detect the welding tension of the air pump cover, so as to determine whether the welding firmness of the air pump cover meets the preset standard; the air outlet pressure detection module detects the air outlet pressure of the air pump, so as to determine whether the air outlet pressure of the air pump meets the preset standard; the no-load tension detection module detects the tension of the air pump when it is no-load, so as to determine whether the tension of the air pump when it is no-load meets the preset standard. The automatic detection mechanism for the air pump of the present invention integrates the welding tension detection module, the air outlet pressure detection module and the no-load tension detection module. In the process of the feeding module feeding the air pump product, the welding tension detection module, the air outlet pressure detection module and the no-load tension detection module can complete the three corresponding performance tests of the air pump product, thereby greatly improving the performance testing efficiency of the product, while effectively reducing labor costs and saving workshop work space, thereby specifically solving the technical problems existing in the existing air pump performance testing equipment.
