Description

Technical Field

[0001] The invention belongs to the technical field of copper pipe quality inspection, and specifically relates to a metal pipe screening device. Background Art

[0002] Copper pipes are also known as red copper pipes; they are a type of non-ferrous metal pipe, which are pressed and drawn seamless pipes. Due to the good electrical conductivity and thermal conductivity of copper pipes, they are often used in conductive accessories and heat dissipation accessories of electronic products. In addition, copper pipes have strong corrosion resistance, are not easily oxidized, and do not easily react chemically with some liquid substances. In modern buildings, copper pipes have gradually become the first choice for the installation of tap water pipes, heating, and refrigeration pipes. During the processing of copper pipes, operations such as deburring, chamfering, and inspection need to be performed on the formed copper pipes.

[0003] When inspecting copper pipes, the length inspection of copper pipes is particularly important. Copper pipes with length errors will affect the ex-factory quality of the entire batch of copper pipes. Therefore, the length inspection of copper pipes is necessary. Currently, the method for inspecting the length of copper pipes is through a displacement sensor. Specifically, the detection head carries a displacement sensor and presses against both ends of the copper pipe, and the length of the copper pipe is detected through the displacement sensor; the detection heads are located on both sides of the detection tooling, and the detection tooling is used for placing the copper pipes; in order to improve the processing efficiency of copper pipes, existing workers will set the copper pipe chamfering and inspection processes to be completed on the same production line. The debris generated during chamfering will splash, and the splashed debris will fall into the detection tooling, and it is easy for the debris to stay between the end of the copper pipe and the detection head during inspection, resulting in deviation of the displacement detected by the detection head, and thus reducing the detection accuracy. Therefore, workers need to regularly clean the detection tooling of copper pipes, which is very inconvenient.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 11 As shown, a metal pipe screening device according to an embodiment of the present invention comprises a workbench 1, a transfer assembly 11 is installed above the workbench 1, a loading plate 12 is installed at the loading end of the workbench 1, a chamfering assembly 13 is installed at the top of the workbench 1, and a cleaning assembly 14 is installed on one side of the chamfering assembly 13 and at the top of the workbench 1; A pair of detection plates 2 are installed at the discharging end of the workbench 1. A partition plate 21 is fixedly connected between the pair of detection plates 2. A first cylinder 211 is fixedly connected to the side surface of the partition plate 21. A first groove is formed on the side of the partition plate 21 away from the first cylinder 211. A push plate 212 is inserted into the first groove. The output end of the first cylinder 211 penetrates into the first groove and is fixedly connected to the push plate 212. A cushion plate 22 is fixedly connected between the pair of detection plates 2. An inclined plate 23 is fixedly connected to the end of the cushion plate 22 away from the partition plate 21. A second cylinder 3 is installed on the side surface of the detection plate 2. The output end of the second cylinder 3 penetrates the detection plate 2, and a connecting member is fixedly connected to the output end of the second cylinder 3. A rectangular box 31 is fixedly connected to the end of the connecting member away from the second cylinder 3. A first nozzle 33 is inserted into the side of the rectangular box 31 facing the center of the pair of detection plates 2. A first air charging pipe 32 is fixedly connected through the top of the detection plate 2. The bottom end of the inclined plate 23 is fixedly connected to a material receiving plate 24. A material discharging notch is formed at the top of the material receiving plate 24. A material discharging plate 241 is arranged inside the material discharging notch. A material discharging motor 242 is installed on the side surface of the material receiving plate 24. The output end of the material discharging motor 242 is fixedly connected to the side surface of the material discharging plate 241. A pair of material receiving boxes 15 are arranged below the material receiving plate 24. Specifically, it includes box one 151 directly below the material discharging notch and box two 152 away from the material discharging notch. At present, when processing copper tubes, first place them on the top of the loading plate 12. The loading plate 12 is set to be inclined, and multiple copper tubes to be detected are stacked on the loading plate 12. Then the transfer component 11 is started. The transfer component 11 is composed of a slide rail, a lifting cylinder, and an electric clamp. Inside the slide rail, there is an orbital car. The lifting cylinder is installed on the orbital car, and the electric clamp is installed on the output end of the lifting cylinder. When transferring the copper tubes on the loading plate 12, the orbital car drives the lifting cylinder to move above the loading plate 12, and then the lifting cylinder drives the electric clamp to move downward. When the electric clamp moves to the clamping position, it stops. Then, the copper tubes on the loading plate 12 are clamped and fixed by the electric clamp. Then, control the electric clamp to move above the chamfering component 13. The chamfering component 13 includes a fixed clamp installed on the top of the workbench 1. At both ends of the fixed clamp, there are chamfering cylinders. The output end of the chamfering cylinder is installed with a chamfering motor, and the output end of the chamfering motor is fixedly connected with a chamfering head. The electric clamp transfers the copper tubes to the fixed clamp of the chamfering component 13, and the copper tubes are fixed by the fixed clamp. Then, the chamfering motor is started to drive the chamfering head to rotate. At the same time, the chamfering cylinder drives the chamfering motor to move, so that the chamfering motor drives the chamfering head to approach the end of the copper tube, and the chamfering head chamfers the end of the copper tube; after the copper tube is chamfered, continue to transfer it above the cleaning component 14. The cleaning component 14 includes a fixed clamp fixed on the top of the workbench 1, and also includes a cleaning cylinder at the end of the fixed clamp. The output end of the cleaning cylinder is fixedly connected with a cleaning head. When cleaning, transfer the copper tube to the fixed clamp of the cleaning component 14, and then start the cleaning cylinder. The output end of the cleaning cylinder drives the cleaning head to insert into the copper tube. The cleaning head is a fluffy filamentous plastic. When the cleaning head inserts into the copper tube, the debris generated by chamfering inside the copper tube will be ejected. Then, transfer the cleaned copper tube between a pair of detection plates 2; When detecting the copper pipe, the second cylinder 3 is started. The second cylinder 3 drives the rectangular box 31 to move and press against the end of the copper pipe, and stops when pressing against the end of the copper pipe. A displacement sensor is installed inside the rectangular box 31. The displacement sensor will record the moving distance of the rectangular box 31, and then analyze whether the length of the copper pipe is qualified. At the same time, when the rectangular box 31 approaches the copper pipe, the first air charging pipe 32 is externally connected to a first air pump. The first air pump inflates the rectangular box 31 through the first air charging pipe 32. The air entering the inside of the rectangular box 31 is ejected through the first nozzle 33. The airflow ejected by the first nozzle 33 acts between a pair of detection plates 2. The air ejected by a pair of first nozzles 33 collides with each other, so that the debris splashed due to the chamfer of the copper pipe between the pair of detection plates 2 is driven to the middle part between the pair of detection plates 2, and then is lifted upward by the airflow, and thus separated from between the pair of detection plates 2, so as to avoid the interference of debris when the rectangular box 31 presses against the end of the copper pipe, that is, to avoid debris staying between the end of the copper pipe and the detection head during detection, resulting in deviation of the detection displacement of the detection head, ensuring the detection accuracy. The staff does not need to regularly clean the debris between the pair of detection plates 2, reducing the workload of the staff, being beneficial to improving the detection efficiency, and making the whole detection process more convenient; when the detection is completed, first cancel the pressing of the rectangular box 31 against the end of the copper pipe, and then the first cylinder 211 is started. The first cylinder 211 drives the push plate 212 to move. The push plate 212 pushes the copper pipe located at the top of the backing plate 22. The copper pipe rolls downward to the top of the receiving plate 24 when moving to the top of the inclined plate 23. When the length of the copper pipe is qualified, the copper pipe will roll on the receiving plate 24 and fall downward into the receiving box 15 below the end of the receiving plate 24, specifically the second box 152. When the copper pipe is detected as unqualified, during the rolling process of the copper pipe on the top of the receiving plate 24, the blanking motor 242 is started to drive the blanking plate 241 to rotate 90 degrees. When the blanking plate 241 rotates 90 degrees, the blanking notch is opened. The copper pipe falls into another receiving box 15 inside when passing through the blanking notch. Specifically, the receiving box 15 below the blanking notch is the container for receiving unqualified copper pipes, which is the first box 151. Then the blanking motor 242 drives the blanking plate 241 to rotate back to its original position to fully block the blanking notch; thus, the screening of unqualified copper pipes is realized; then the above operations are repeated to detect and screen a batch of copper pipes; it should be noted that the first cylinder 211, the second cylinder 3 and the blanking motor 242 are all controlled by a microcomputer, and the displacement sensor inside the rectangular box 31 is connected to the microcomputer through an electrical signal.

[0023] As Figures 3 to 9As shown, the end of the detection plate 2 away from the partition 21 is rotatably connected to the interception plate 5, and a feed notch is provided at the bottom end of the interception plate 5. A collecting cylinder 51 is fixedly connected to the side of the interception plate 5 away from the detection plate 2, and the collecting cylinder 51 is connected to the feed notch. The collecting cylinder 51 includes a horizontal part and an inclined part. The horizontal part is connected to the feed notch, and the top end of the inclined part is connected to the bottom end of the horizontal part. The inclined direction of the inclined part is downward along the horizontal plane, and a filter screen 511 is slidably connected in the inclined part; a second nozzle 213 is inserted on the side of the partition 21 facing the interception plate 5 and located below the push plate 212, and the top end of the partition 21 is inserted A second air-filling pipe 214 is connected, and the bottom end of the second air-filling pipe 214 is connected to the second nozzle 213; when cleaning the debris between a pair of detection plates 2, the first nozzle 33 sprays air to drive the debris on the pad 22 to concentrate to the middle position of the pad 22, and the second air-filling pipe 214 is externally connected to a second air pump, and the second air pump inflates the second nozzle 213 through the second air-filling pipe 214, and the second nozzle 213 sprays air to drive the debris located in the middle part of the pad 22 into the feed gap, and then enters the collection tube 51 through the feed gap, and is filtered and collected by the filter net 511 inside the collection tube 51; to achieve The collection of debris is convenient for later cleaning; it should be pointed out that the height of the second nozzle 213 is higher than that of the first nozzle 33, and the second nozzle 213 sprays air downward at an angle, so the convective air sprayed by the first nozzle 33 is difficult to drive the debris to splash upward and separate from the pair of detection plates 2, and the debris will be blown into the feed gap. In addition, when the push plate 212 pushes the copper tube to separate from between the pair of detection plates 2, the copper tube will push the interception plate 5, so that the interception plate 5 deflects relative to the detection plate 2, and then the bottom end of the copper tube interception plate 5 passes over; the bottom end of the interception plate 5 contacts the top end of the pad 22 to prevent debris from passing through the pad 22 and the interception plate 5 The debris will be discharged through the gap between the backing plate 22 and the intercepting plate 5 when the second nozzle 213 sprays airflow. In addition, when the intercepting plate 5 is deflected, the collecting cylinder 51 will deflect synchronously. The inclined portion of the collecting cylinder 51 will not be horizontal when the collecting cylinder 51 is deflected, that is, the inclined portion of the collecting cylinder 51 will still maintain a downward tilt, so the debris collected in the inclined portion will not flow back and pour out; and magnets are provided at the bottom of the intercepting plate 5 and inside the pad 22, and they attract each other. Therefore, when the second nozzle 213 sprays airflow, the intercepting plate 5 will not deflect to cause a gap between the pad 22 and the intercepting plate 5, thereby ensuring that the debris enters the feed gap; in addition, the cleaning should be carried out before the copper tube enters between a pair of detection plates 2 to avoid the copper tube obstructing the airflow.

[0024] like Figures 8 to 9As shown, a baffle 514 is fixedly connected to the bottom end of the inclined part. An early warning device 515 is fixedly connected to the side of the baffle 514 facing the inside of the collection cylinder 51. A pair of rubber blocks 513 are fixedly connected to the side of the filter net 511 facing the baffle 514. One end of the rubber block 513 away from the filter net 511 is fixedly connected to the baffle 514. A top block 512 is fixedly connected to the side of the filter net 511 facing the baffle 514. As the content of the debris collected by the filter net 511 increases, the pores on the filter net 511 are gradually blocked, and the thrust generated by the airflow on the filter net 511 when passing through the filter net 511 gradually increases, so that the extrusion force of the filter net 511 on the rubber block 513 gradually increases, causing the rubber block 513 to be gradually squeezed and contracted. The filter net 511 drives the top block 512 to gradually approach the baffle 514. When the top block 512 on the side of the filter net 511 moves to contact the early warning device 515 and presses its switch button, the early warning device 515 is activated, sending a warning signal to the microcomputer outside, and the microcomputer sends an alarm signal to the computer outside, prompting the staff to clean the debris collected inside the collection cylinder 51, preventing the collection cylinder 51 from losing its collection function due to excessive debris inside.

[0025] As Figures 11 to 16As shown in the figure, a positioning plate 6 is arranged on one side of the rectangular box 31 facing the center of a pair of detection plates 2. A pair of positioning blocks 61 are fixedly connected to the surface of the positioning plate 6. A rectangular groove is formed on the side of the positioning block 61 away from the positioning plate 6. A pair of positioning columns 62 are inserted into the rectangular groove. One end of the positioning column 62 located inside the rectangular groove is slidably connected to the inner wall of the rectangular groove. A cross bar 64 is fixedly connected inside the rectangular groove. The cross bar 64 horizontally penetrates through the part of the positioning column 62 located inside the rectangular groove. A pair of buffer springs are sleeved at both ends of the positioning column 62. The end of the buffer spring close to the positioning column 62 is fixedly connected to the positioning column 62. The end of the positioning column 62 located outside the rectangular groove is set to be a tip. The connecting member is specifically a third cylinder 311. The housing part of the third cylinder 311 is connected to the output end of the second cylinder 3. A linkage frame is fixedly connected between the output end of the third cylinder 311 and the rectangular box 31. When detecting the length of the copper pipe, the rectangular box 31 drives the positioning plate 6 to move synchronously. The positioning plate 6 drives the positioning columns 62 on the positioning blocks 61 to move synchronously. When moving, the two pairs of positioning columns 62 will be inserted into the ends of the copper pipe. A pair of positioning columns 62 are respectively located on the inner and outer sides of the copper pipe. During detection, the third cylinder 311 drives the rectangular box 31 to move upward through the linkage frame. The rectangular box 31 drives the positioning plate 6 to move upward. The positioning plate 6 drives the positioning block 61 to move upward. The positioning block 61 drives the positioning column 62 to move upward. A pair of positioning columns 62 drive the copper pipe to move upward, so that the copper pipe is suspended during detection, which can avoid the debris carried on the outer surface of the copper pipe from propping up the copper pipe and causing it to tilt relative to the perpendicular line of the pair of detection plates 2, ensuring the detection accuracy. It should be noted that during the processing of the copper pipe, coolant will be used in operations such as copper pipe cutting. The coolant remaining on the surface of the copper pipe will cause debris to adhere, so the debris is easily attached to the outer surface of the copper pipe. In addition, the end of the positioning column 62 located outside the rectangular groove is set to be a tip, so that the copper pipe can be easily inserted between the pair of positioning columns 62, and copper pipes of different thicknesses can squeeze the tips of the positioning columns 62, so that the positioning columns 62 slide along the cross bar 64, and the buffer spring is used to improve the buffer and pressing force, so that the pair of positioning columns 62 press against the inner and outer surfaces of the copper pipe.

[0026] As Figures 16 to 18 shown, a rotating cylinder 63 is sleeved on the surface of the positioning column 62. A layer of rubber ring is fixedly connected to the surface of the rotating cylinder 63. A plurality of guiding strips 631 are arranged on one side of the rotating cylinder 63 close to the tip of the positioning column 62. One end of the guiding strip 631 is connected to the surface of the tip part of the positioning column 62, and the other end is aligned with the outer cylinder surface of the rotating cylinder 63. A guiding chamfer is arranged at the connection between the guiding strip 631 and the positioning column 62. When the end of the copper pipe is inserted between the pair of positioning columns 62, the end of the copper pipe will be guided to the surface of the rotating cylinder 63 through the guiding strip 631 on the surface of the tip of the positioning column 62. Since a layer of rubber ring is fixedly connected to the surface of the rotating cylinder 63, the rubber ring contacts the copper pipe instead of the rotating cylinder 63, thereby protecting the copper pipe. The setting of the guiding chamfer avoids the end of the copper pipe from being blocked by the guiding strip 631 when the copper pipe moves.

[0027] As shown Figure 14 in the figure, the side surface of the positioning plate 6 is set to be arc-shaped, and a toothed plate 71 is provided on one side of the positioning plate 6. A connecting frame 7 is fixedly connected between the top end of the toothed plate 71 and the top end of the detection plate 2. A plurality of teeth are provided on the side of the positioning plate 6 close to the toothed plate 71. The teeth provided on the side surface of the positioning plate 6 are meshed with the toothed plate 71; the positioning plate 6 is rotatably connected to the rectangular box 31; when the positioning plate 6 moves upward, the teeth on the side surface of the positioning plate 6 will be meshed and driven with the toothed plate 71, and the positioning plate 6 is rotatably connected to the rectangular box 31. Therefore, when the positioning plate 6 moves upward, it rotates synchronously. The positioning plate 6 drives the positioning block 61 to rotate, and the positioning block 61 drives the copper tube to rotate synchronously through a pair of positioning columns 62. At the same time, the second spray head 213 is controlled to spray air. The air sprayed by the second spray head 213 acts on the surface of the copper tube, so that the debris attached to the surface of the copper tube is driven off by the air flow. As the copper tube rotates, it is ensured that different positions on the surface of the copper tube can be acted on by the air flow, ensuring the cleaning effect of the surface of the copper tube; it should be noted that the rubber ring on the surface of the rotating cylinder 63 can increase the friction force between the copper tube and the positioning column 62, ensuring that the copper tube can be driven to rotate.

[0028] As shown Figure 11 in the figure, a pair of support frames 4 are symmetrically fixedly connected to the side of the rectangular box 31 close to the center of the pair of detection plates 2. The end of the support frame 4 far from the rectangular box 31 is fixedly connected with a guiding plate 41. The guiding plate 41 includes an inclined part and a vertical part. The bottom end of the inclined part is fixedly connected to the top end of the vertical part. The end of the support frame 4 is fixedly connected to the side surface of the vertical part. The distance between the pair of vertical parts is the same as the diameter of the copper tube to be detected; when the copper tube is transferred between the pair of detection plates 2 by the electric clamp, the guiding plate 41 will guide the copper tube through the inclined part, and cooperate with the vertical part so that the placement position of the copper tube can be received by the pair of positioning columns 62, ensuring that the copper tube is restricted from being lifted by the pair of positioning columns 62.

[0029] As shown Figures 16 to 18 in the figure, a pair of air cylinders 83 are fixedly connected inside the rectangular groove. An air plate 82 is slidably connected inside the air cylinder 83. A squeezing tube 81 is fixedly connected and communicated to the side of the air plate 82 facing outside the air cylinder 83. One end of the squeezing tube 81 far from the air plate 82 is fixedly connected with an air outlet head 8; when the end is inserted between the pair of positioning columns 62, the air outlet head 8 is squeezed at the same time. When the air outlet head 8 is squeezed, it drives the air plate 82 at the end of the squeezing tube 81 to move into the air cylinder 83. The gas inside the air cylinder 83 is squeezed and enters the air outlet head 8 through the squeezing tube 81, and then sprays out from the air outlet head 8 and acts on the end of the copper tube to clean the debris attached to the end of the copper tube, avoiding the debris remaining at the end of the copper tube from interfering with the detection accuracy; the air outlet head 8 can be squeezed into the rectangular groove, and the end of the copper tube is received by the positioning block 61.

[0030] As shown Figure 18As shown, a filter cover is fixedly connected to the opening of the air outlet head 8, and the filter cover is used to filter the debris generated in the chamfering process of the copper tube; by setting the filter cover, the air sprayed from the air outlet head 8 can be dispersed to the surroundings through the filter cover, so that the air sprayed from the air outlet head 8 is dispersed to all positions of the end of the copper tube, ensuring that the end of the copper tube is completely cleaned by the air flow; it should be pointed out that a return spring is arranged inside the air cylinder 83, and when the air outlet head 8 is not squeezed, the return spring drives the air plate 82 to return to its original position.

[0031] like Figures 3 to 4 As shown, a mounting plate 9 is fixedly connected to the side of the material receiving box 15, and a pair of inclined plates 91 are fixedly connected to the side of the mounting plate 9. The pair of inclined plates 91 are distributed up and down, and the upper inclined plate 91 will fall onto the lower inclined plate 91 after being guided to the copper tube, and finally the copper tube will roll into the lower material receiving box 15 through the lower inclined plate 91; the copper tube falling from the material receiving plate 24 will fall onto the upper inclined plate 91, and then fall onto the lower inclined plate 91, and finally the copper tube will roll into the lower material receiving box 15 through the lower inclined plate 91, so as to avoid the copper tube falling directly from the material receiving plate 24 into the material receiving box 15 to produce a large impact, thereby causing surface damage.
