Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning production, and in particular to a blockage detection device. Background Art

[0002] In air conditioning systems, capillary tubes serve as important throttling devices, reducing pressure, cooling temperature, and regulating refrigerant flow. This throttling effect is achieved by exploiting the resistance of the refrigerant flowing through the slender tubes. Brazing is the primary method for connecting capillary tubes in air conditioning systems. Due to the narrow internal channels (inner diameter less than or equal to 2.4mm), excessive brazing flux can flow down the brazing seam to the bottom of the tube opening due to manual addition of flux or secondary repairs to the joints. This can then cool and form a weld nub, blocking the tube opening and impacting the overall performance of the air conditioning system.

[0003] In order to prevent the use of welded plugged products in air-conditioning devices, plugging detection equipment is usually added to the production line to perform flow detection on small-diameter capillary devices. To ensure the effectiveness and yield of plugging detection for all capillary devices, the existing plugging detection equipment requires manual cooperation during the plugging detection process. For products that pass or fail the inspection, the plugging detection equipment uses different colored sound and light alarm devices to prompt. According to the sound and light alarm prompts, the operator uses a marker to mark the surface of the qualified product as a qualified inspection mark, and then flows it into the subsequent process, which releases it based on this mark. If the inspection fails, the operator will perform explosive destruction on the product on site and scrap it to prevent the unqualified capillary from being repaired again.

[0004] However, the above methods have defects that are uncontrollable due to human subjective operation: unqualified products are treated as qualified products due to human fatigue misjudgment, unqualified products are mixed with qualified products because they are not destroyed on site in time, products are directly marked without being inspected, the position of the marking is not obvious and the handwriting is not clear, resulting in failure of full process control of the product, etc. Summary of the Invention

[0035] The blockage detection device of the present invention includes not only a blockage detection device 10 for detecting whether a pipe at a detection position is blocked, but also a marking device 20 and a scrapping device 30. When the blockage detection device 10 detects that the pipe is qualified, the marking device 20 marks the pipe; when the blockage detection device 10 detects that the pipe is unqualified, the scrapping device 30 scraps the pipe. This blockage detection device automates the marking of qualified pipes and the marking and scrapping of unqualified pipes, eliminating the need for manual processing. This improves detection accuracy and solves the problem of low detection accuracy caused by the need for subjective human operation of the blockage detection device.

[0036] It should be noted that qualified pipe fittings are those that have been tested to be unblocked, and unqualified pipe fittings are those that have been tested to be blocked.

[0037] In this embodiment, the marking device 20 includes: a first driving member 21, which is connected to the blockage detection device 10; and a code spraying gun 22, which is connected to the first driving member 21, so that the first driving member 21 drives the code spraying gun 22 to move to perform code marking on the pipe located at the detection position.

[0038] During specific implementation, the inkjet printer 22 can spray codes on qualified pipes for permanent marking; and the first driving member 21 drives the inkjet printer 22 to move to the inspection position to spray codes on the pipes, and moves to the avoidance position after coding to avoid interference with other components.

When the first extrusion member 31 and the second extrusion member 32 are both moved in the direction toward the detection position, the first extrusion member 31 and the second extrusion member 32 squeeze the tube. When the first extrusion member 31 and the second extrusion member 32 are both moved in the direction away from the detection position, the first extrusion member 31 and the second extrusion member 32 release the tube.

[0041] In specific implementation, when the blockage detection device 10 detects that the pipe is unqualified, the first extrusion member 31 and the second extrusion member 32 both move toward the detection position, that is, they move toward each other to squeeze the pipe, so that the pipe is destroyed and scrapped.

[0042] In this embodiment, the blockage detection equipment also includes a fixing sleeve 40, which is connected to the blockage detection device 10; the fixing sleeve 40 has a fixing hole 41 for accommodating the pipe fitting, and when the pipe fitting is in the detection position, the pipe fitting is inserted into the fixing hole 41; the fixing sleeve 40 also includes a first channel 42 and a second channel 43, both of which are connected to the fixing hole 41, and the first extrusion member 31 is movably arranged in the first channel 42 to squeeze the pipe fitting in the fixing hole 41; the second extrusion member 32 is movably arranged in the second channel 43 to squeeze the pipe fitting in the fixing hole 41.

[0043] In specific implementation, the extrusion ends of the first extrusion member 31 and the second extrusion member 32 are both located in the first channel 42 and the second channel 43, which can prevent the operator from being injured by touching the first extrusion member 31 and the second extrusion member 32, thereby improving the safety of the blockage detection equipment.

[0044] Optionally, the first extrusion member 31 and the second extrusion member 32 are both cutters.

[0045] In this embodiment, the scrapping device 30 further includes: a second driving member 33, which is connected to the blocking detection device 10; a first transmission assembly, the second driving member 33 is connected to the first transmission assembly, so that the second driving member 33 drives at least a portion of the first transmission assembly to perform reciprocating linear motion along a first preset direction, and at least a portion of the first transmission assembly is connected to the first extruding member 31, so that the first extruding member 31 performs reciprocating linear motion under the action of at least a portion of the first transmission assembly; wherein the moving direction of the first extruding member 31 is perpendicular to the first preset direction; and / or a third driving member 34, which is connected to the blocking detection device 10; a second transmission assembly, the third driving member 34 is connected to the second transmission assembly, so that the third driving member 34 drives at least a portion of the second transmission assembly to perform reciprocating linear motion along the first preset direction, and at least a portion of the second transmission assembly is connected to the second extruding member 32, so that the second extruding member 32 performs reciprocating linear motion under the action of at least a portion of the second transmission assembly; wherein the reciprocating direction of the second extruding member 32 is perpendicular to the first preset direction, and the first preset direction is Figure 7 The up and down directions in .

[0046] Optionally, the second driving member and the third driving member are both cylinders.

[0047] In this embodiment, the scrapping device 30 further includes a first guide portion 35, which is fixedly connected to the fixing sleeve 40 and has a first guide channel 351 and a second guide channel 352 that are interconnected. The first transmission assembly includes a first push rod 37, and the second driving member 33 is drivingly connected to the first push rod 37 so that the first push rod 37 is movably disposed in the first guide channel 351. The first push rod 37 is provided with a first push inclined surface 371 on the side facing the second extruding member 32. The first push inclined surface 371 is inclined relative to a first predetermined direction so that when the first push rod 37 moves, the first push inclined surface 371 abuts against the first extruding member 31, driving the first extruding member 31 toward the detection position. The first extruding member 31 is movably disposed in the second guide channel 352.

[0048] In specific implementations, the first inclined push surface 371 can convert the movement of the first push rod 37 along a first predetermined direction into the movement of the first extruding member 31 along a second predetermined direction. The second predetermined direction is the direction toward and away from the detection position, i.e., the direction of reciprocating movement of the first extruding member 31 and the second extruding member 32. The first guide portion 35 can guide and limit the movement of the first push rod 37 and the first extruding member 31, ensuring reliable movement.

[0049] In this embodiment, the scrapping device 30 further includes a first elastic member 391 , a first end of the first elastic member 391 is connected to the first extruding member 31 , and a second end of the first elastic member 391 is connected to the fixing sleeve 40 or the first guide portion 35 .

[0050] In a specific implementation, after the first push rod 37 is reset, the first elastic member 391 can cause the first extruding member 31 to move in a direction away from the fixing hole 41 under the action of elastic force, so as to be reset.

[0051] In this embodiment, the scrapping device 30 further includes a second guide portion 36 fixedly connected to the fixing sleeve 40 and having a third guide channel 361 and a fourth guide channel 362 that communicate with each other. The second transmission assembly includes a second push rod 38, and the third driving member 34 is drivingly connected to the second push rod 38 so that the second push rod 38 is movably disposed in the third guide channel 361. The second push rod 38 is provided with a second inclined surface 381 on a side facing the second extruding member 32. The second inclined surface 381 is inclined relative to the first predetermined direction so that when the second push rod 38 moves, the second inclined surface 381 abuts against the second extruding member 32, driving the second extruding member 32 toward the detection position. The second extruding member 32 is movably disposed in the fourth guide channel 362. The scrapping device 30 further includes a second elastic member 392, a first end of which is connected to the second extruding member 32, and a second end of which is connected to the fixing sleeve 40 or the second guide portion 36. It should be noted that the structure and principle of the second transmission assembly are the same as those of the first transmission assembly, and the structure and principle of the second elastic member 392 are the same as those of the first elastic member 391 .

[0052] Optionally, the second elastic member 392 and the first elastic member 391 are both springs.

[0053] In this embodiment, the blockage detection equipment also includes: a connecting piece 50, which is detachably connected to the blockage detection device 10, and the marking device 20 and the scrapping device 30 are both arranged on the connecting piece 50, so that the marking device 20 and the scrapping device 30 are both connected to the blockage detection device 10 through the connecting piece 50.

[0054] During specific implementation, the marking device 20 and the scrapping device 30 are both arranged on the connecting member 50 to form an integrated structure, which is convenient for quick replacement, disassembly and fixation.

[0055] Specifically, the first driving member 21, the second driving member and the third driving member are all connected to the connecting member 50, so that the marking device 20 and the scrapping device 30 are both arranged on the connecting member 50; the fixing sleeve 40 is fixedly connected to the connecting member 50 through the connecting rod, and the integrated structure formed here is convenient for quick replacement, disassembly and fixation.

[0056] In this embodiment, the blockage detection device 10 includes a mounting seat 11 and a blockage detection mold 12 arranged on the mounting seat 11, and the blockage detection mold 12 is used to detect whether the pipe is blocked; the connecting piece 50 is a clamp, and the clamp is detachably connected to the mounting seat 11.

[0057] During specific implementation, the clamp is put on the mounting seat 11, and according to the structure of the inspection product, the clamp is rotated to adjust the optimal position to avoid the interference position between the inspection product and the marking device 20 and the scrapping device 30 during the inspection process. Finally, the clamp is fixed to the inspection device through the fixing bolts of the clamp. The setting of the clamp can rotate 360 degrees during the production process to perfectly avoid special products with interfering structures with the equipment.

[0058] Specifically, the detection mold 12 has a detection hole, and when the pipe is in the detection position, one end of the pipe is inserted into the detection hole, so that the detection mold 12 can detect the pipe inserted in the detection hole.

[0059] Specifically, the diameter of the fixing hole 41 is 2 mm to 3 mm larger than the diameter of the pipe. This arrangement effectively prevents employees' fingers from being inserted by mistake, thereby improving safety.

[0060] In specific implementation, the blockage detection equipment has an audio and optical alarm signal source to prompt whether the detected pipe is qualified or unqualified through the audio and optical alarm signal source.

[0061] In the specific implementation, before the blockage inspection, the parameters of the inkjet printer are first set to set the characters to be coded on the surface of the product. The operator inserts the pipe into the blockage inspection mold 12 and starts the equipment blockage inspection program. The blockage inspection equipment clamps the pipe to perform blockage inspection. When the equipment passes the blockage inspection, a qualified signal is sent to the marking device 20. The marking device 20 starts the first driving member to push the inkjet printer 22 forward. The inkjet printer 22 synchronously executes the inkjet printer to spray characters on the surface of the pipe exposed on the outside of the blockage inspection mold 12 to form a permanent inspection mark character. Finally, the blockage inspection device releases the workpiece. , the operator takes out the workpiece; when the blocking inspection device sends an unqualified signal to the marking device 20, the first driving member of the marking device 20 does not move, and the second driving members and the third driving members on the left and right sides are started to move forward synchronously, and the first pushing inclined surface 371 of the first push rod 37 and the second pushing inclined surface 381 of the second push rod 38 are used to push the left and right push knives (i.e., the first extrusion member 31 and the second extrusion member 32) toward the fixing hole 41, forcibly squeezing and destroying the pipe fitting, and finally the blocking inspection device releases the workpiece, and the operator takes out the workpiece for scrapping.

[0062] The technical problem addressed by this application is to utilize the audio and visual alarm signal sources of the blockage detection equipment to permanently mark qualified pipe fittings and destroy unqualified ones, thereby increasing the quality control function of the product (i.e., pipe fittings) after blockage detection without affecting the normal blockage detection function and efficiency of the product. Furthermore, the blockage detection equipment can quickly switch between functional devices when the product changes molds, while also perfectly avoiding interference with the blockage detection process for products with special structures.

[0063] All small-diameter copper pipes in the air conditioning industry are at risk of plugging after brazing, requiring full product inspection and control using plugging detection equipment. Due to the wide variety of product shapes and shapes, over 80% of these inspections still rely on manual inspections. This can lead to missed inspections and mis-inspections, resulting in the mixing of unqualified products with qualified ones, requiring significant manpower and material resources for rectification. By adding product plugging control (i.e., marking device 20 and scrapping device 30) to the existing plugging detection equipment, 100% effective control over the entire plugging inspection process for small-diameter products in air conditioning systems is achieved. The inspection quality mark is permanent and cannot be forged, enhancing consumer confidence in product quality.

[0064] This application utilizes the characteristics of inkjet coding technology combined with the characteristics of blockage detection equipment to ensure that the inspection marks on the copper tubes of the air-conditioning system cannot be forged, and the surface quality marks will not fall off permanently; through the hidden inlaid two-way extrusion technology, the safety of operators can be guaranteed when the copper tubes of unqualified products are instantly destroyed.

[0065] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0066] The blockage detection device of the present invention includes not only a blockage detection device 10 for detecting whether a pipe at a detection position is blocked, but also a marking device 20 and a scrapping device 30. When the blockage detection device 10 detects that the pipe is qualified, the marking device 20 marks the pipe; when the blockage detection device 10 detects that the pipe is unqualified, the scrapping device 30 scraps the pipe. This blockage detection device automates the marking of qualified pipes and the marking and scrapping of unqualified pipes, eliminating the need for manual processing. This improves detection accuracy and solves the problem of low detection accuracy caused by the need for subjective human operation of the blockage detection device.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
