Detailed Implementation

[0030] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0031] Please refer to Figures 3-7 The present invention provides a hot-press end-feed detection device 200, including a housing 210, a detection mechanism 220 and a connecting mechanism 230.

[0032] The housing 210 has a receiving cavity. The detection mechanism 220 includes a vacuum valve 221, a pressure detection element 222, several connecting pipes 223, and several air passage interfaces 224. The inlet of the vacuum valve 221 is used to communicate with a gas source, and the outlet of the vacuum valve 221 is connected to each of the air passage interfaces 224 via the connecting pipes 223. The vacuum valve 221 can be in a suction state or a blowing state. When the vacuum valve 221 is in a suction state, a negative pressure is formed at the outlet of the vacuum valve 221. When the vacuum valve 221 is in a blowing state, gas is ejected from the outlet of the vacuum valve 221. The pressure detection element 222 is used to detect the air pressure at the outlet of the vacuum valve 221. Each of the connecting pipes 223 is provided with a switching valve 225, and each of the air passage interfaces 224 is fixed to the housing 210.

[0033] The vacuum valve has a built-in vacuum generator. The vacuum generator works by using a nozzle to inject compressed air at high speed (in this embodiment, the compressed air comes from an air source), forming a jet at the nozzle outlet, thus generating entrainment flow. Under the action of entrainment, the air around the nozzle outlet is continuously drawn in, reducing the pressure inside the adsorption chamber to below atmospheric pressure, creating a certain degree of vacuum. Therefore, the vacuum generator can convert the kinetic energy of the compressed air provided by the air source into the energy source for air intake at the vacuum valve outlet, thereby realizing the air intake function. As for the air blowing function of the vacuum valve, it is achieved directly by connecting the outlet of the vacuum valve to the air source. The specific structure of the vacuum valve is prior art and will not be described in detail in this invention.

[0034] The connecting mechanism 230 is disposed on the housing 210 and is used to connect with the quick connector 110 of the thermo-pressing end effector 100. When the connecting mechanism 230 is connected to the quick connector 110, each of the air passage interfaces 224 is connected to each of the air holes 112 on the quick connector 110.

[0035] Before the hot-press end effector 100 is put online, the connecting mechanism 230 of the offline detection device 200 is connected to the quick-connect connector 110 of the hot-press end effector 100. At this time, each of the air passage interfaces 224 is connected to each of the air holes 112 on the quick-connect connector 110, so that each of the air passage interfaces 224 is connected to each of the suction cups 150 of the hot-press end effector 100. Then, one switching valve 225 is opened (the other switching valves 225 are in the closed state), and then the vacuum valve 221 is switched to the suction state. A plate is attached to the suction cup 150. At this time, the gas in the suction cup 150 corresponding to the currently opened switching valve 225 is drawn into the vacuum valve 221 and then discharged into the air. A negative pressure is created at the outlet of vacuum valve 221. If suction cup 150 malfunctions and its sealing deteriorates, outside air will continuously enter the outlet of vacuum valve 221 through suction cup 150. At this time, the air pressure at the outlet of vacuum valve 221 will increase (the vacuum degree is lower than the design value). The air pressure at the outlet of vacuum valve 221 is detected by air pressure detection device 222 to determine whether the suction cup 150 is experiencing a material suction failure. Then, vacuum valve 221 is switched to blowing mode, and by observing whether the plate is detached from suction cup 150, it can be determined whether the suction cup 150 is experiencing a material detachment failure. The same method is used to test other suction cups 150 until the test is completed. Thus, this device can realize offline testing of hot press end effector 100, allowing problems to be detected offline in advance, and timely repairs or replacement of parts can be carried out to ensure the normal and stable function of hot press end effector 100 on the line without occupying online time, thereby improving production efficiency.

[0036] For easy adjustment of the suction and blowing states of vacuum valve 221, please refer to... Figures 4-7In a preferred embodiment, the vacuum valve 221 is provided with an air intake / air blowing switching knob 2211, which is used to put the vacuum valve 221 into an air intake state or an air blowing state. The air intake / air blowing switching knob 2211 is located on the surface of the housing 210.

[0037] To provide electrical power to vacuum valve 221, please refer to... Figures 4-6 In a preferred embodiment, the detection mechanism 220 further includes a power supply 226, which is installed in the receiving cavity and electrically connected to the vacuum valve 221.

[0038] For easy connection to the gas source, please refer to... Figures 4-6 In a preferred embodiment, the detection mechanism 220 further includes an air inlet pipe 227, one end of which is connected to the inlet of the vacuum valve 221, and the other end of which is connected to an air source.

[0039] For details on how to implement the function of the connecting mechanism 230, please refer to... Figures 2-9 In a preferred embodiment, an annular groove 1111 is formed on the inner sidewall of the insertion hole 111 of the quick connector 110; the connecting mechanism 230 includes a connecting block 231 and a locking drive member 232. The connecting block 231 is fixed to the housing 210. A plurality of notches 2311 are formed on the sidewall of the connecting block 231. A locking block 233 is movably disposed in each notch 2311. The locking drive member 232 is connected to each locking block 233 and is used to drive each locking block 233 to rotate synchronously, so that each locking block 233 is synchronously inserted into or synchronously removed from the annular groove 1111, thereby realizing the connection between the connecting block 231 and the quick connector 110.

[0040] To understand the specific functions of the locking drive 232, please refer to [reference needed]. Figures 2-9In a preferred embodiment, the locking drive 232 includes a mounting base 2321, a lifting block 2322, a lifting drive 2323, and a plurality of rotating blocks 2324. The mounting base 2321 is fixed to the housing 210. The lifting block 2322 is slidably disposed on the mounting base 2321. The lifting drive 2323 is connected to the lifting block 2322 and is used to drive the lifting block 2322 to move up and down. The first end of each rotating block 2324 is hinged to the mounting base 2321. The second end of each rotating block 2324 is provided with an oblong hole (not shown). A connecting shaft 2325 is slidably inserted into each oblong hole. The connecting shaft 2325 is hinged to the lifting block 2322. Each locking block 2324 is divided into... The first end of the corresponding rotating block 2324 is fixed. In use, when the lifting drive 2323 drives the lifting block 2322 to move upward, the lifting block 2322 drives the second end of each rotating block 2324 to rise, so that each rotating block 2324 will rotate around its own first end, thereby driving each locking block 233 to rotate. During the rotation, when the locking block 233 is facing upward, the locking block 233 is located in the notch 2311. At this time, the insertion hole 111 of the quick connector 110 can be inserted into the connecting block 231. Then, the lifting drive 2323 drives the lifting block 2322 to move upward, thereby driving each locking block 233 to rotate, so that the locking block 233 rotates into the annular groove 1111 of the quick connector 110, thereby locking the quick connector 110.

[0041] To understand the specific functions of the lifting drive component 2323, please refer to [the relevant documentation / reference]. Figures 2-9 In a preferred embodiment, the lifting drive 2323 is a quick-connect cylinder, and the output shaft of the quick-connect cylinder is fixedly connected to the lifting block 2322. In this embodiment, the housing 210 is also provided with a quick-connect cylinder control knob 2326, which is used to control the action of the quick-connect cylinder.

[0042] To improve the locking effect, please refer to... Figures 2-9 In a preferred embodiment, the number of notches 2311 and lock blocks 233 are both four.

[0043] For easier positioning of the quick-connect connector 110, please refer to... Figures 2-9 In a preferred embodiment, the quick-connect connector 110 is further provided with a positioning pin 113; the connecting block 231 is further provided with a positioning hole 2312 that cooperates with the positioning pin 113, and the positioning hole 2312 is used for the positioning pin 113 to be inserted.

[0044] To improve the fit between the locating pin 113 and the locating hole 2312, please refer to... Figures 2-9In a preferred embodiment, there are two positioning pins 113 and two positioning holes 2312.

[0045] To better understand this invention, the following is combined with... Figures 1-9 The working process of the offline testing device for the hot-pressed end effector provided by the present invention will be described in detail as follows: Before the hot-pressed end effector 100 is put online, the connecting mechanism 230 of the offline testing device 200 is connected to the quick-connect connector 110 of the hot-pressed end effector 100. The quick-connect cylinder control knob 2326 is rotated to lock the quick-connect connector 110. At this time, each of the air passage interfaces 224 is connected to each of the air holes 112 on the quick-connect connector 110, so that each of the air passage interfaces 224 is connected to each of the suction cups 150 of the hot-pressed end effector 100. Then, one switching valve 225 is opened (the other switching valves 225 are in the closed state). Then, the vacuum valve 221 is switched to the suction state by the suction and blowing switching knob 2211, and a plate is attached to the suction cup 150. At this time, the suction cup corresponding to the currently opened switching valve 225 is activated. The gas inside the suction cup 150 is drawn into the vacuum valve 221 and then discharged into the air, thus creating a negative pressure at the outlet of the vacuum valve 221. If the suction cup 150 malfunctions and its sealing performance deteriorates, outside air will continuously enter the outlet of the vacuum valve 221 through the suction cup 150. At this time, the air pressure at the outlet of the vacuum valve 221 will increase (the vacuum degree is lower than the design value). The air pressure at the outlet of the vacuum valve 221 is detected by the air pressure detection element 222, which can determine whether the suction cup 150 currently being tested has a material suction failure. Then, the vacuum valve 221 is switched to the blowing state by the suction and blowing switching knob 2211. By observing whether the board is detached from the suction cup 150, it can be determined whether the suction cup 150 currently being tested has a material detachment failure. The same method is used to test other suction cups 150 until the testing is completed. This device enables offline testing of the hot-press end effector 100, allowing problems to be detected in advance offline. This allows for timely repair or replacement of parts, ensuring the normal and stable function of the hot-press end effector 100 when it is online, without taking up online time and improving production efficiency.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
