Description

Technical Field

[0001] The invention relates to the technical field of radiators, and in particular to a radiator solder joint air tightness testing device. Background Art

[0002] A heat sink is a key component used to transfer and release heat to ensure that a system or device operates within a normal temperature range. It is widely used in computers, automobiles, industrial equipment, and many electronic products, playing an important role in heat management. Heat sinks are usually made of high thermal conductivity materials that can effectively absorb and disperse the heat generated by the heat source. When working, the heat sink contacts the heat source, conducts the heat to its surface, and then uses air flow or liquid circulation to take the heat away and discharge it into the surrounding environment. The heat sink is an indispensable part of modern electronic equipment and industrial systems.

[0003] The radiator is mainly responsible for the cooling of circulating water. Most of its water pipes and heat sinks are made of aluminum, and welding is usually required during the production process. However, the welding at the welding points of the radiator may be unstable, which will lead to poor air tightness of the radiator. Therefore, the radiator needs to undergo an air tightness test before leaving the factory. The current air tightness test device seals the two ends of the radiator and connects the air inlet and outlet pipes respectively, and then ventilates the inside of the radiator. If there is a problem with the air tightness of the radiator, pressure relief will occur, but it cannot accurately find the specific location of the weld that is not welded well. In addition, it is inconvenient to flip the radiator during use. When the leak point appears at the bottom, the leak position cannot be observed and determined. When the radiator is manually immersed in water again, the efficiency of the test is affected, and there are certain disadvantages in the use process.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Specific examples are given below.

[0024] like Figure 1-Figure 8 As shown, a radiator solder joint air tightness test device comprises a test pool 1 and a radiator body 2, the radiator body 2 is composed of a heat sink 201 and a water pipe 202, an air inlet joint 203 and an air outlet joint 204 are installed on the water pipe 202, a vertical mounting frame 3 is fixedly installed on the side wall of the test pool 1, a vertical mounting slot is provided on the vertical mounting frame 3, a lifting drive component 4 is installed in the vertical mounting slot, a horizontal mounting bar 5 is installed on the lifting drive component 4, a limiting slide slot is provided on the horizontal mounting bar 5, a flip clamping and positioning component 6 is installed in the limiting slide slot, and the flip clamping and positioning component 6 is used to adjust the radiator The body 2 is clamped and fixed so that the radiator body 2 is located above the pool. An L-shaped mounting frame 7 is fixedly installed on the top of the horizontal mounting bar 5. A push-type position adjustment component 8 is installed on the L-shaped mounting frame 7. A suspension frame 9 is installed on the push-type position adjustment component 8. A horizontal position adjustment groove is opened on the top of the suspension frame 9. A lateral displacement adjustment component 11 is installed in the lateral position adjustment groove. An angle-adjustable contact mark component 10 is installed on the lateral displacement adjustment component 11. The angle-adjustable contact mark component 10 is located above the welding point of the water pipe 202. When in use, the radiator body 2 is placed in an appropriate position above the test pool 1. The height of the horizontal mounting bar 5 is adjusted by the lifting drive component 4 so that the flip-type clamping and positioning component 6 can firmly clamp the radiator body 2. After clamping, ensure that the radiator body 2 is stably suspended above the pool. Next, operate the push-type position adjustment component 8 to move the suspension frame 9 and the angle-adjustable contact mark component 10 thereon to just above the welding point of the water pipe 202. Inflate the water pipe 202 through the air inlet joint 203 and observe whether there are bubbles coming out of the welding point to judge the air tightness of the welding point. Adjust the angle position of the angle-adjustable contact marking component 10 as needed to ensure that it can accurately contact and mark the leakage position of the welding point.

[0025] The lifting drive assembly 4 includes a servo motor 401 and a vertical threaded rod 402. The servo motor 401 is fixed on the inner wall of one end of the vertical mounting groove. The vertical threaded rod 402 is rotatably mounted on the inner wall of the other end of the vertical mounting groove through a first rotating joint 403, and one end of the vertical threaded rod 402 is fixedly connected to the output shaft of the servo motor 401. A threaded slider 404 is installed on the vertical threaded rod 402. The threaded slider 404 is slidably clamped in the vertical mounting groove. An L-shaped connecting plate 405 is fixedly installed on the threaded slider 404. The horizontal mounting bar 5 is fixed at one end of the L-shaped connecting plate 405. When in use, the servo motor 401 is started, and its output shaft drives the vertical threaded rod 402 to rotate. Since the vertical threaded rod 402 is installed at the other end of the vertical mounting groove through the first rotating joint 403, it can rotate stably without axial movement. As the vertical threaded rod 402 rotates, the threaded slider 404 slides up and down in the vertical mounting groove along the thread direction. The L-shaped connecting plate 405 fixed on the threaded slider 404 moves accordingly, thereby driving the horizontal mounting block 5 and all components thereon to rise and fall, so that the radiator body 2 can be stably and accurately lifted to the designated position above the test pool 1, which is convenient for subsequent clamping and fixing and water air tightness testing.

[0026] The flip-type clamping and positioning assembly 6 includes a driving motor 601 and a bidirectional lead screw 602. The driving motor 601 is fixed on the inner wall of one end of the limiting slide. The bidirectional lead screw 602 is rotatably installed on the inner wall of the other end of the limiting slide through a second rotating joint 603.

The clamping slider 604 is slidably engaged in the limiting slide. There are two clamping sliders 604. The two clamping sliders 604 are respectively located at the reverse thread ends of the bidirectional lead screw 602. The first serpentine connecting rod 605 and the second serpentine connecting rod 606 are respectively fixedly mounted on the block 604, and a waterproof motor 607 and a rotating column 608 are respectively mounted on one end of the first serpentine connecting rod 605 and the second serpentine connecting rod 606, and a first U-shaped clamping plate 609 is fixedly connected to the output shaft of the waterproof motor 607, and a second U-shaped clamping plate 610 is fixedly mounted on one end of the rotating column 608, and soft friction blocks 611 are fixedly mounted on the inner walls of the first U-shaped clamping plate 609 and the second U-shaped clamping plate 610. When in use, the driving motor 601 is started, and its output shaft drives the bidirectional lead screw 602 to rotate. Since the bidirectional lead screw 602 is provided with reverse screw teeth, the two clamping slide blocks 604 will move to the middle or both sides at the same time. When the radiator body 2 needs to be clamped, the two clamping slide blocks 604 move toward each other until the first U-shaped clamping plate 609 and the second U-shaped clamping plate 610 are close to the two sides of the radiator body 2 respectively, and the first U-shaped clamping plate 609 rotates to firmly clamp the radiator body 2 together with the second U-shaped clamping plate 610, and the soft friction block 611 is designed to increase the clamping force and protect the radiator body 2 from damage. After the clamping is completed, the radiator body 2 is raised to the test position by the lifting drive assembly 4 for subsequent air tightness testing, and at this time, the waterproof motor 607 is started, and its output shaft drives the first U-shaped clamping plate 609 to rotate and the second U-shaped clamping plate 610 to rotate, so as to realize the flip adjustment of the radiator body 2, so as to facilitate the multi-directional air tightness detection of the welding point.

[0027] The push-type position adjustment assembly 8 includes a position adjustment block 801 and a lateral mounting seat 802. The position adjustment block 801 is slidably engaged in the hollow chute provided on the L-shaped mounting frame 7. The lateral mounting seat 802 is fixed on the side wall of the L-shaped mounting frame 7. A transverse telescopic push rod 803 is fixedly mounted on the lateral mounting seat 802. The position adjustment block 801 is fixedly connected to the telescopic end of the transverse telescopic push rod 803 through an extended clamping head 804. The suspended frame 9 is fixed to the position adjustment block 801 through a vertical block 805. When in use, the position adjustment block 801 is slidably engaged in the hollow chute of the L-shaped mounting frame 7 to ensure that it can slide smoothly. Then, the transverse telescopic push rod 803 is fixed by the lateral mounting seat 802 fixed on the side wall of the L-shaped mounting frame 7. Subsequently, the telescopic end of the transverse telescopic push rod 803 is fixedly connected to the extended clamping head 804 on the position adjustment block 801 to achieve linkage between the two. Finally, the suspended frame 9 is firmly fixed on the position adjustment block 801 through the vertical block 805. By operating the transverse telescopic push rod 803, the position of the suspended frame 9 can be conveniently adjusted to achieve accurate positioning.

[0028] The angle-adjustable contact marking assembly 10 includes a semicircular mounting seat 1001, which is fixed on the lateral adjustment assembly 11. The semicircular mounting seat 1001 is provided with an arc-shaped card slot, in which an arc-shaped slider 1002 is slidably connected, and the arc-shaped slider 1002 is slidably connected to an arc-shaped groove provided on the inner wall of the arc-shaped card slot through an arc-shaped limit head 1010, which is used to limit the arc-shaped slider 1002, so that the arc-shaped slider 1002 is more stable. A vertical telescopic rod 1003 is fixedly installed on the arc-shaped slider 1002, and a marking printing head 10 is fixedly installed at the telescopic end of the vertical telescopic rod 1003. 04, a bent connecting plate 1005 is fixedly installed on the arc-shaped slider 1002, and a positioning pin 1006 is slidably installed on the bent connecting plate 1005. One end of the positioning pin 1006 is inserted into the corresponding positioning pin holes on the arc-shaped slider 1002 and the semicircular mounting seat 1001, and the other end of the positioning pin 1006 is fixedly installed with a lifting handle 1007. An annular pad 1008 is fixedly sleeved on the positioning pin 1006, and the annular pad 1008 is elastically connected to the bent connecting plate 1005 through a positioning spring 1009. When in use, the marking and printing head 1004 is adjusted to an appropriate height through the vertical telescopic rod 1003. Then, the arc-shaped slider 1002 is slid in the arc-shaped slot, so that the marking and printing head 1004 can be aligned with the welding point on the radiator water pipe 202 from different angles. After the adjustment is completed, the positioning pin 1006 is inserted into the positioning pin holes on the arc-shaped slider 1002 and the semicircular mounting seat 1001 by pulling the handle 1007 to fix the arc-shaped slider 1002. The design of the annular pad 1008 and the positioning spring 1009 ensures the stability of the positioning pin 1006 during the insertion process. When it is necessary to fine-tune the angle of the marking and printing head 1004, it is only necessary to gently pull out the positioning pin 1006, and slide and fix the arc-shaped slider 1002 to the desired position again, so that the marking and printing head 1004 can accurately and stably contact and mark the welding point, which is convenient for the subsequent analysis of the airtightness test results.

[0029] The transverse adjustment assembly 11 includes a micro motor 1101 and a transverse ball screw 1102. The micro motor 1101 is fixed on the inner wall of one end of the transverse position adjustment groove. The transverse ball screw 1102 is rotatably mounted on the inner wall of the other end of the transverse position adjustment groove through a rotating connection seat 1103. One end of the transverse ball screw 1102 is fixedly connected to the output shaft of the micro motor 1101. A transverse adjustment block 1104 is threadedly mounted on the transverse ball screw 1102. The transverse adjustment block 1104 is slidably engaged in the transverse position adjustment groove. The semicircular mounting seat 1001 is fixed on the transverse adjustment block 1104. When in use, the micro motor 1101 is started, and the motor is fixed on the inner wall of one end of the transverse position adjustment groove. As the micro motor 1101 is started, its output shaft starts to rotate, thereby driving the transverse ball screw 1102 fixedly connected thereto to rotate under the support of the rotating connection seat 1103. The rotational motion of the transverse ball screw 1102 is converted into the linear motion of the transverse adjustment block 1104 through the threaded transmission. The transverse adjustment block 1104 slides along the axial direction of the transverse ball screw 1102 and remains stable due to the sliding engagement in the transverse position adjustment groove. As the transverse adjustment block 1104 moves, the semicircular mounting seat 1001 fixed thereon also moves, thereby realizing the transverse position adjustment of the equipment or components mounted on the semicircular mounting seat 1001. According to actual needs, the transverse position of the semicircular mounting seat 1001 and the equipment or components it carries can be accurately adjusted by controlling the forward and reverse rotation and rotation time of the micro motor 1101.

[0030] When the present invention is used, first, the radiator body 2 is placed in a suitable position above the test pool 1, ensuring that the radiator fins 201 and the water pipes 202 of the radiator body 2 are in a state that is easy to operate and test. The structure of the radiator body 2 consists of the radiator fins 201 and the water pipes 202, wherein the water pipes 202 are pre-installed with an air inlet connector 203 and an air outlet connector 204, which will be used for subsequent inflation tests.

[0031] Next, start the lifting drive assembly 4 to adjust the height of the horizontal mounting bar 5. The lifting drive assembly 4 is composed of a servo motor 401 and a vertical threaded rod 402. The servo motor 401 is fixed on the inner wall of one end of the vertical mounting groove, and the vertical threaded rod 402 is rotatably mounted on the inner wall of the other end through a first rotating joint 403, and one end of the vertical threaded rod 402 is fixedly connected to the output shaft of the servo motor 401. After starting the servo motor 401, its output shaft will drive the vertical threaded rod 402 to rotate. Since the vertical threaded rod 402 is installed through the first rotating joint 403, it can rotate stably without axial movement. As the vertical threaded rod 402 rotates, the threaded slider 404 will slide up and down in the vertical mounting groove along the thread direction, and drive the L-shaped connecting plate 405 fixed on the threaded slider 404 to move, thereby lifting the horizontal mounting bar 5 and all components thereon. By precisely controlling the rotation of the servo motor 401 , the radiator body 2 can be stably and accurately lifted to a designated position above the test water pool 1 , which is convenient for subsequent clamping and water tightness testing.

[0032] When the horizontal installation bar 5 reaches the appropriate height, the flip-type clamping and positioning assembly 6 is then used to clamp and fix the radiator body 2. The flip-type clamping and positioning assembly 6 includes a driving motor 601 and a bidirectional lead screw 602. The driving motor 601 is fixed on the inner wall of one end of the limiting slideway, and the bidirectional lead screw 602 is rotatably installed on the inner wall of the other end of the limiting slideway through a second rotating joint 603, and one end of the bidirectional lead screw 602 is fixedly connected to the output shaft of the driving motor 601. After the driving motor 601 is started, its output shaft will drive the bidirectional lead screw 602 to rotate. Since the bidirectional lead screw 602 is provided with reverse screw teeth, the two clamping sliders 604 will move toward the middle at the same time. When the two clamping sliders 604 move toward each other to the appropriate position, the first serpentine connecting rod 605 and the second serpentine connecting rod 606 fixed on the clamping slider 604 will respectively drive the waterproof motor 607 and the rotating column 608 to move until the first U-shaped clamping plate 609 and the second U-shaped clamping plate 610 are respectively close to the two sides of the radiator body 2. At this time, the waterproof motor 607 is started, and its output shaft will drive the first U-shaped clamping plate 609 to rotate, and together with the second U-shaped clamping plate 610, the radiator body 2 is firmly clamped. The soft friction block 611 is designed to increase the clamping force and protect the radiator body 2 from damage.

[0033] After the clamping is completed, the radiator body 2 is raised to the test position by the lifting drive assembly 4, and is ready for the subsequent air tightness test. At this time, the push-type position adjustment assembly 8 can be operated to adjust the position of the suspended frame 9 and the angle-adjustable contact mark assembly 10 thereon. The push-type position adjustment assembly 8 includes a position adjustment block 801 and a lateral mounting seat 802. The position adjustment block 801 is slidably engaged in the hollow slide groove provided on the L-shaped mounting frame 7, while the lateral mounting seat 802 is fixed on the side wall of the L-shaped mounting frame 7, and a transverse telescopic push rod 803 is fixedly installed. By operating the telescopic end of the transverse telescopic push rod 803, the position of the position adjustment block 801 and the suspended frame 9 fixed on the position adjustment block 801 can be easily adjusted to achieve precise positioning.

[0034] After the suspended frame 9 reaches the appropriate position, the lateral adjustment component 11 is controlled to adjust the position and angle of the angle-adjustable contact marking component 10 to ensure that it can accurately contact and mark the leakage position of the welding point. The angle-adjustable contact marking component 10 includes a semicircular mounting seat 1001, and an arc-shaped card slot is provided on the semicircular mounting seat 1001 for slidingly engaging the arc-shaped slider 1002. By sliding the arc-shaped slider 1002, the angles of the vertical telescopic rod 1003 and the marking printing head 1004 fixed on the arc-shaped slider 1002 can be adjusted. After the adjustment is completed, the positioning pin rod 1006 is inserted into the positioning pin holes on the arc-shaped slider 1002 and the semicircular mounting seat 1001 by pulling the handle 1007 to fix the arc-shaped slider 1002. The design of the annular pad 1008 and the positioning spring 1009 ensures the stability of the positioning pin rod 1006 during the insertion process.

[0035] Finally, perform an air tightness test. Inflate the water pipe 202 through the air inlet joint 203, and observe whether there are bubbles coming out of the welding point. If you need to fine-tune the position or angle of the marking and dyeing head 1004, just gently pull out the positioning pin rod 1006, and slide and fix the arc-shaped slider 1002 to the desired position again. Once bubbles are found, the leaking position can be marked by the marking and dyeing head 1004 to facilitate subsequent analysis and processing.
