Description

Technical Field

[0001] The invention relates to the technical field of water distribution spacer detection technology, in particular to a water distribution spacer detection device with an automatic screening function. Background Art

[0002] At present, in the CDI water circuit, the gap between the outer circle of the motor and the mold tube is too large, too much water is stored, and too much mixed water is produced when switching between regeneration and water production, which easily leads to the phenomenon that concentrated water becomes dilute and fresh water becomes concentrated, reducing the efficiency of CDI. The water distribution spacer can evenly support the CDI electrode in the mold tube, keep the distance between the outer circle of the CDI electrode and the mold tube equal, so as to ensure that the water flow and flow rate of the outer circle of the CDI remain uniform.

[0003] Water distribution spacers are mostly produced by injection molding equipment. Since the molding quality cannot be accurately controlled during the injection molding process, and the water distribution spacers will be impacted by water flow during use, it is necessary to add testing equipment to perform quality inspection on the molded water distribution spacers.

[0004] In addition, the water distribution spacer is generally composed of a ring and strip ribs. Since the strip ribs inside the ring are densely distributed, conventional testing equipment cannot guarantee the detection accuracy. Summary of the invention

[0005] The object of the present invention is to provide a water distribution spacer detection device with an automatic screening function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A water distribution spacer detection device with automatic screening function, the detection device is used to detect the molding quality of the water distribution spacer, the water distribution spacer includes a ring and strip ribs, the strip ribs are flat, the detection device includes a shell, a conveying device and a prestressed device, the conveying device is used to convey the water distribution spacer, the conveying device is connected to the shell, the prestressed device is connected to the shell, the prestressed device is connected to the conveying device for transmission connection, and the prestressed device is used to detect the connection strength of the ring and the strip ribs.

[0008] The water-distributing spacer uses a circular ring as the main support body, and a plurality of strip ribs are arranged in the middle of the inner ring. The strip ribs include three states: long, medium and short. A medium strip rib is arranged between two adjacent long strip ribs, and a short strip rib is arranged between the long strip ribs and the medium strip ribs. The connection strength of the strip ribs and the circular ring in the three states is inspected by the detection equipment, and the molding quality of the strip ribs themselves is inspected. The shell is used as the main supporting foundation for the installation and fixation of other devices, and the water-distributing spacer is transported through the conveying device, and the prestressing device is driven to move at the same time to inspect the water-distributing spacer.

[0009] Furthermore, a conveying path is provided on the shell, and the conveying device includes a conveying belt, which is arranged along the conveying path. A working chamber is provided on the shell, and the working chamber is connected to the conveying path. A plurality of clamps are provided on the conveying belt, and a clamping groove is provided on the clamping seat. The water distribution isolation sheet is placed in the clamping groove, and the clamping groove is vertically through-set.

[0010] The prestressed device includes an air distribution component and a detection component. The air distribution component is used to apply multi-directional force to the strip reinforcement. The detection component is connected to the air distribution component, and the detection component is used to detect defects in the strip reinforcement.

[0011] Power rollers are built into both ends of the conveyor path to output torque and drive the conveyor belt to rotate. During inspection, the working chamber provides inspection space, and the air distribution component and the inspection component are sent into the working chamber for inspection. Several holders are set on the conveyor belt, and the water distribution isolation piece is limited by the positioning groove to facilitate continuity inspection. Multi-directional pressure is applied to the strip ribs through the air distribution component. When the formed strip ribs themselves and the connection strength between the strip ribs and the rings do not meet the use requirements, the strip ribs are deformed through multi-directional force, and the deformation position is detected by the inspection component, so as to automatically screen out unqualified products. The deformation of the defective parts is magnified through multi-directional force, which is convenient for improving the inspection accuracy.

[0012] Furthermore, an opening is provided on the side of the working chamber, and the conveying device also includes a circulation component, which is used to circulate the air distribution component, and the air distribution component includes an air outlet tube and an air collection tube, which are respectively fastened to the circulation component, and the air outlet tube and the air collection tube are respectively located on both sides of the base, and the air outlet tube outlet is connected to the positioning groove, and the prestressed device also includes an air induced draft duct, which is connected to the air outlet tube pipeline, and a guide paddle is provided in the air outlet tube, and the guide paddle is a propeller blade.

[0013] The working chamber is set with an opening on one side facing the circulation component. The circulation component is used to drive the air distribution component to move, so as to facilitate multi-directional force application to the water distribution isolation plate in turn. The air outlet tube and the air collection tube are respectively fixed at the displacement output end of the circulation component to facilitate circulation detection. The air outlet tube is connected to the induced draft duct, and the induced draft duct is connected to the high-pressure air source to supply air. When the airflow enters the air outlet tube, it is first rectified. After the rectification is completed, it flows to the guide paddle. The guide paddle includes a paddle shaft and a paddle blade. Through the spiral setting of the paddle blade, the airflow flows along the surface of the paddle blade and then spirals forward along the air outlet tube. When it flows out through the air outlet tube outlet, it obliquely flows toward the strip ribs, thereby oblique force is applied to the strip ribs to amplify local defects. Through spiral air supply, it is convenient to amplify defects of multiple strip ribs at the same time, thereby improving detection efficiency.

[0014] Furthermore, the detection component includes a light source, a light receiving plate and an electrode column. The light source is placed in the air outlet duct, and the light path of the light source is toward the strip ribs. The light receiving plate is placed in the air outlet duct, and a plurality of photosensitive layers are provided on the light receiving plate. Each photosensitive layer is provided with two electrode columns. The light emitted by the light source irradiates the photosensitive layer, and the photosensitive layer is located below the gap between two adjacent strip ribs.

[0015] When the defects of the strip ribs are magnified by spiral air supply, parallel light is emitted through the light source in the air outlet tube, and the direction of the parallel light is arranged vertically. When it is irradiated on the strip ribs, it is blocked by the strip ribs. The two electrode columns are electrically connected to the two terminals of the power supply. The gaps between the strip ribs leak light and irradiate the lower photosensitive layer to stimulate electron-hole pairs to participate in conduction. At this time, it is full-power conduction, and the current of the formed detection circuit is the largest. When there are defects in the strip ribs, they are deformed by force, so that the deformed part blocks the light path at the rear end of the force direction, which reduces the amount of light transmitted. The current of the circuit with reduced light transmittance is reduced and is lower than the standard value, thereby automatically screening the quality of the water-distributing isolation plate.

[0016] Furthermore, the circulation component includes a frame and a circulation chain. The frame is tightly connected to the shell. Two circulation grooves are provided on the frame. The two circulation grooves are located at different floor heights. The circulation chains are arranged along the two circulation grooves respectively. The circulation chain and the circulation grooves are slidingly connected. The circulation chain is tightly connected to the adjacent air outlet duct and air collection duct. The air outlet duct and air collection duct located at the same floor height are staggered.

[0017] The stand is fixed on the shell, and the circulation chain is guided by the upper and lower circulation grooves. The circulation chain includes a number of chain links, and the adjacent chain links are hingedly connected. The air outlet and air collection tubes at different heights are fixed by the circulation chain, so as to drive the air outlet and air collection tubes to perform circulation movement. By setting different floor heights and staggering the air outlet and air collection tubes at the same height, spiral downward air supply and spiral upward air supply are respectively performed, so as to perform multi-directional air supply and improve the detection accuracy.

[0018] Furthermore, the upper guide propeller and the guide propeller at the rear end of the lower layer have the same rotation direction, and the adjacent guide propellers at the same layer height have opposite rotation directions.

[0019] The feeding direction of the conveyor belt is the main movement direction. After the guide paddles on the upper layer tilt downward to supply air, the air is collected through the air collecting duct directly below to reduce turbulence interference. After that, the guide paddles at the rear end adopt the same rotation direction and tilt upward to supply air, so that the two air supply directions are in different directions of the same straight line in the force direction area of ​​the strip ribs. Since the guide paddles are only arranged in the air outlet duct, after the guide paddles at the lower end supply air, the guide paddles with opposite rotation directions are driven by the circulating chain to enter the inspection station. After the inspection is completed, the subsequent guide paddles are driven to supply air, so that the same water distribution isolation plate is subjected to four-way force, which is convenient for improving the detection accuracy of the strip ribs.

[0020] Furthermore, a limit cylinder is provided at the lower end of the card seat, and the axial distance between adjacent air outlet tubes and air receiving tubes is equal to the center distance between adjacent card seats;

[0021] When qualified: the output end of the limit cylinder is retracted, and the limit cylinder is not in contact with the air outlet or air collection cylinder;

[0022] When defective: the output end of the limit cylinder extends out, and the output end of the limit cylinder abuts against the outer circle of the adjacent air outlet or air collection cylinder.

[0023] When the water distribution isolation plate is a qualified product, the current of the detection circuit does not fluctuate through the four-way force application, and a new water distribution isolation plate is sent to the detection station through the conveyor belt for continuity detection; when the water distribution isolation plate is a defective product, the circuit current fluctuates during a certain process of applying the four-way force. Through this current signal, the output end of the limit cylinder is extended and abuts against the air outlet or air intake tube at the rear, so that when the circulating chain moves, the conveyor belt is driven to move through the limit cylinder and the holder in turn, and the defective products are sent out of the detection station, and the subsequent four-way detection is not continued, thereby improving the detection efficiency.

[0024] Furthermore, the circulation component also includes a driving motor and a sprocket, the driving motor and the stand are fastened together, the output end of the driving motor is drivingly connected to the adjacent sprocket, at least two sprockets are provided in the circulation groove, the sprockets and the circulation groove are rotatably connected, and the sprockets at the same height are driven by the circulation chain.

[0025] The driving motor is the main power source during the circulation process of the circulating chain. It is fixed on the test stand and drives the adjacent sprockets to rotate by outputting torque. The sprockets are driven by the circulating chain, thereby performing four-way detection on the water distribution isolation plate of the detection station to improve the detection accuracy.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: multi-directional pressure is applied to the strip ribs through the air distribution component. When the formed strip ribs themselves and the connection strength between the strip ribs and the circular rings do not meet the use requirements, the strip ribs are deformed by applying force in multiple directions. The deformation position is detected by the detection component, so that unqualified products are automatically screened. The deformation of the defective parts is magnified by applying force in multiple directions, which is convenient for improving the detection accuracy. The guide paddle includes a paddle shaft and a paddle blade. Through the spiral arrangement of the paddle blade, the air flow flows along the surface of the paddle blade and then spirally advances along the air outlet cylinder. When it flows out through the outlet of the air outlet cylinder, it flows obliquely toward the strip ribs, thereby applying oblique force to the strip ribs and magnifying local defects. Through the spiral air supply, it is convenient to magnify the defects of multiple strip ribs at the same time, thereby improving the detection efficiency. Through the light source in the air outlet cylinder, parallel light is emitted. The direction of the parallel light is arranged vertically. When irradiated on the strip ribs, it is blocked by the strip ribs. The two electrode columns are electrically connected to the two wiring terminals of the power supply. The light leaks through the gaps and shines on the photosensitive layer at the bottom, exciting electron-hole pairs to participate in conduction. At this time, it is full-power conduction, and the current of the formed detection circuit is the largest. When there are defects in the strip ribs, they are deformed by force, so that the deformed part blocks the light path at the rear end of the force direction, which reduces the amount of light passing through. The current of the circuit with reduced light passing through is reduced and is lower than the standard value, thereby automatically screening the quality of the water-distributing isolation sheet; after the upper guide paddle tilts downward to supply air, the air is collected through the air collecting duct directly below to reduce turbulent interference. Thereafter, the guide paddle at the rear end adopts the same rotation direction and tilts upward to supply air, so that the two air supply directions are in different directions of the same straight line in the force application direction area of ​​the strip ribs; since the guide paddles are only arranged in the air outlet duct, after the guide paddle at the lower end supplies air, the guide paddle with the opposite rotation direction is driven into the detection station through the circulating chain, and the subsequent guide paddles are driven to supply air after the detection is completed, so that the same water-distributing isolation sheet is subjected to four-way force, which is convenient for improving the detection accuracy of the strip ribs.

[0040] The prestressing device 3 includes an air distribution component 31 and a detection component 32. The air distribution component 31 is used to apply multi-directional force to the strip reinforcement. The detection component 32 is connected to the air distribution component 31 and is used to detect defects in the strip reinforcement.

[0041] Power rollers are built into both ends of the conveyor path 11 for outputting torque and driving the conveyor belt 21 to make a rotational motion. During the inspection, the working chamber 12 provides an inspection space, and the air distribution component 31 and the detection component 32 are sent into the working chamber 12 for inspection. A number of holders 22 are arranged on the conveyor belt 21, and the water distribution isolation plate 4 is limited by the positioning groove 221 to facilitate continuity inspection. Multi-directional pressure is applied to the strip ribs through the air distribution component 31. When the formed strip ribs themselves and the connection strength between the strip ribs and the circular rings do not meet the use requirements, the strip ribs are deformed through multi-directional force application, and the deformation position is detected by the detection component 32, so that unqualified products are automatically screened. The deformation of the defective parts is magnified through multi-directional force application, which is convenient for improving the inspection accuracy.

[0042] Furthermore, the side opening of the working chamber 12 is provided, and the conveying device 2 also includes a circulation component 23, and the circulation component 23 is used to circulate the air distribution component 31, and the air distribution component 31 includes an air outlet duct 311 and an air collection duct 313, and the air outlet duct 311 and the air collection duct 313 are respectively fastened to the circulation component 23, and the air outlet duct 311 and the air collection duct 313 are respectively located on both sides of the base 22, and the outlet of the air outlet duct 311 is connected to the positioning groove 221, and the prestressed device 3 also includes an air duct 33, and the air duct 33 is connected to the air outlet duct 311, and a guide paddle 312 is provided in the air outlet duct 311, and the guide paddle 312 is a propeller blade.

[0043] The working chamber 12 is opened toward one side of the circulation component 23. The circulation component 23 is used to drive the air distribution component 31 to move, so as to facilitate multi-directional force application to the water distribution isolation plate 4 in turn. The air outlet 311 and the air collection duct 313 are respectively fixed at the displacement output end of the circulation component 23, so as to facilitate circulation detection. The air outlet 311 is connected to the air duct 33, and the air duct 33 is connected to the high-pressure air source for air supply. When the airflow enters the air outlet 311, it is first rectified. After the rectification is completed, it flows to the guide paddle 312. The guide paddle 312 includes a paddle shaft and a paddle blade. Through the spiral arrangement of the paddle blade, the airflow flows along the surface of the paddle blade and then spirally moves forward along the air outlet 311. When it flows out through the outlet of the air outlet 311, it flows obliquely toward the strip ribs, thereby oblique force is applied to the strip ribs, local defects are amplified, and the spiral air supply makes it convenient to amplify defects of multiple strip ribs at the same time, thereby improving the detection efficiency.

[0044] Furthermore, the detection component 32 includes a light source 321, a light receiving plate 322 and an electrode column 324. The light source 321 is placed in the air outlet tube 311. The light path of the light source 321 is toward the strip ribs. The light receiving plate 322 is placed in the air outlet tube 313. A plurality of photosensitive layers 323 are provided on the light receiving plate 322. Each photosensitive layer 323 is provided with two electrode columns 324. The light emitted by the light source 321 irradiates the photosensitive layer 323. The photosensitive layer 323 is located below the gap between two adjacent strip ribs.

[0045] When the defects of the strip ribs are magnified by spiral air supply, parallel light is emitted through the light source 321 in the air outlet tube 311. The direction of the parallel light is arranged vertically. When it is irradiated on the strip ribs, it is blocked by the strip ribs. The two electrode columns 324 are electrically connected to the two terminals of the power supply. The gaps between the strip ribs leak light and irradiate the lower photosensitive layer 323, exciting electron-hole pairs to participate in conduction. At this time, it is full-power conduction, and the current of the formed detection circuit is the largest. When there are defects in the strip ribs, they are deformed by force, so that the deformed part blocks the light path at the rear end of the force direction, which reduces the amount of light transmitted. The current of the circuit with reduced light transmittance is reduced and is lower than the standard value, thereby automatically screening the quality of the water-distributing isolation plate 4.

[0046] Furthermore, the circulation component 23 includes a stand 231 and a circulation chain 232. The stand 231 is tightly connected to the shell 1. Two circulation grooves 2311 are provided on the stand 231. The two circulation grooves 2311 are located at different floor heights. The circulation chain 232 is arranged along the two circulation grooves 2311 respectively. The circulation chain 232 and the circulation grooves 2311 are slidingly connected. The circulation chain 232 and the adjacent air outlet ducts 311 and air collection ducts 313 are tightly connected. The air outlet ducts 311 and air collection ducts 313 located at the same floor height are staggered.

[0047] The stand 231 is fixed on the shell 1, and the circulation chain 232 is guided for circulation through the upper and lower circulation grooves 2311. The circulation chain 232 includes a plurality of chain links, and the adjacent chain links are hingedly connected. The air outlet 311 and the air collecting duct 313 at different heights are fixed through the circulation chain 232, so as to drive the air outlet duct 311 and the air collecting duct 313 to perform circulation motion. By setting different floor heights and staggering the air outlet duct 311 and the air collecting duct 313 at the same floor height, spiral downward air supply and spiral upward air supply are respectively performed, and multi-directional air supply is performed to improve the detection accuracy.

[0049] The feeding direction of the conveyor belt 21 is the main movement direction. After the guide paddles 312 on the upper layer supply air at an angle downward, the air is collected through the air collecting duct 313 directly below to reduce turbulence interference. Thereafter, the guide paddles 312 at the rear end adopt the same rotation direction and supply air at an angle upward, so that the two air supply directions are in different directions of the same straight line in the force application direction area of ​​the strip ribs. Since the guide paddles 312 are only arranged in the air outlet duct 311, after the guide paddles 312 at the lower end supply air, the guide paddles 312 with the opposite rotation direction are driven by the circulating chain 232 to enter the detection station. After the detection is completed, the subsequent guide paddles 312 are driven to supply air, so that the same water distribution isolation plate 4 is subjected to four-way force, so as to improve the detection accuracy of the strip ribs.

[0050] Furthermore, a limit cylinder 24 is provided at the lower end of the holder 22, and the axial center distance between adjacent air outlet cylinders 311 and air collection cylinders 313 is equal to the center distance between adjacent holders 22;

[0052] When there is a defect: the output end of the limit cylinder 24 extends out, and the output end of the limit cylinder 24 abuts against the outer circle of the adjacent air outlet cylinder 311 or air collection cylinder 313.

[0053] When the water distribution isolation plate 4 is a qualified product, the detection circuit current does not fluctuate through the four-way force application, and the new water distribution isolation plate 4 is sent to the detection station through the conveyor belt 21 for continuity detection; when the water distribution isolation plate 4 is a defective product, the circuit current fluctuates during a certain process of the four-way force application, and the output end of the limit cylinder 24 is extended through this current signal, and abuts against the air outlet 311 or the air collection duct 313 at the rear, so that when the circulating chain 232 moves, the conveyor belt 21 is driven to move through the limit cylinder 24 and the holder 22 in turn, and the defective products are sent out of the detection station, and the subsequent four-way detection is not continued, thereby improving the detection efficiency.

[0054] Furthermore, the circulation component 23 also includes a driving motor 233 and a sprocket 234. The driving motor 233 and the stand 231 are fastened together. The output end of the driving motor 233 is transmission-connected to the adjacent sprocket 234. At least two sprockets 234 are provided in the circulation groove 2311. The sprocket 234 and the circulation groove 2311 are rotationally connected. The sprockets 234 and the circulation chain 232 at the same height are chain-driven.

[0055] The driving motor 233 is the main power source during the circulation process of the circulating chain 232. It is fixed on the stand 231 and drives the adjacent sprocket 234 to rotate by outputting torque. The sprocket 234 is chain-driven with the circulating chain 232, thereby performing four-way detection on the water distribution isolation plate 4 of the detection station to improve the detection accuracy.

[0056] The working principle of the present invention is as follows: a multi-directional pressure is applied to the strip ribs through the air distribution component 31. When the formed strip ribs themselves and the connection strength between the strip ribs and the rings do not meet the use requirements, the strip ribs are deformed through multi-directional force application, and the deformation position is detected by the detection component 32, so that unqualified products are automatically screened. The deformation of the defective parts is magnified through multi-directional force application, which is convenient for improving the detection accuracy; the guide paddle 312 includes a paddle shaft and a paddle blade. The paddle blade is spirally arranged, and the airflow flows along the surface of the paddle blade and then flows along the outlet. The air cylinder 311 moves forward in a spiral, and when it flows out through the outlet of the air cylinder 311, it flows obliquely toward the strip ribs, thereby applying an oblique force to the strip ribs, amplifying local defects, and by supplying air in a spiral, it is convenient to amplify defects of multiple strip ribs at the same time, thereby improving the detection efficiency; the light source 321 in the air cylinder 311 emits parallel light, and the direction of the parallel light is arranged vertically. When it is irradiated on the strip ribs, it is blocked by the strip ribs. The two electrode columns 324 are electrically connected to the two terminals of the power supply, and the gaps between the strip ribs are leaked, and the light is irradiated. The light is projected onto the lower photosensitive layer 323, exciting electron-hole pairs to participate in conduction. At this time, the conduction is at full power, and the current of the detection circuit is the largest. When there are defects in the strip ribs, they are deformed by force, so that the deformed part blocks the light path at the rear end of the force direction, reducing the amount of light passing through. The circuit current with reduced light passing through is reduced and is lower than the standard value, thereby automatically screening the quality of the water-distributing isolation sheet 4; after the upper guide paddle 312 tilts downward to supply air, the air is collected through the air collecting duct 313 directly below to reduce turbulence interference. Thereafter, the guide paddle 312 at the rear end adopts the same rotation direction and supplies air obliquely upward, so that the two air supply directions are in different directions of the same straight line in the force direction area of ​​the strip ribs; since the guide paddle 312 is only arranged in the air outlet 311, after the guide paddle 312 at the lower end completes the air supply, the guide paddle 312 with the opposite rotation direction is driven by the circular chain 232 to enter the inspection station, and after the inspection is completed, the subsequent guide paddle 312 is driven to supply air, thereby applying force to the same water distribution isolation plate 4 in four directions, thereby improving the detection accuracy of the strip ribs.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
