Description

Technical Field

[0001] This application relates to the field of measurement technology, and in particular to a device for detecting the height of tin surfaces. Background Technology

[0002] With the development of electronic technology, soldering has become a common production assembly process widely used in the production of electronic information components. Before soldering, the solder needs to be melted into a liquid state at a high temperature and stored in a high-temperature solder bath. After each soldering, the amount of solder in the solder bath decreases accordingly, causing the solder surface to drop. The height of the solder surface affects the amount and height of solder on the component, so it is necessary to repeatedly measure the solder surface height.

[0003] Because the temperature of tin in its liquid state often reaches hundreds of degrees Celsius, placing the sensor in the high-temperature area above the tin surface for extended periods can easily damage the measuring device. To address this issue, common tin surface detection mechanisms often use a combination of cylinders to drive the sensor, enabling it to move up, down, and laterally. This allows the sensor to be positioned above the tin surface during detection to measure its height, and then leaves the high-temperature area after detection. This method not only involves numerous cylinder movements and a complex structure but is also inefficient, affecting the tinning efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a solder surface height detection device to address the problems of common solder surface detection mechanisms being driven by multiple cylinders, resulting in numerous cylinder actions and structural duplication.

[0005] This application provides a solder surface height detection device, comprising: a support base; a measuring component including a sensor for detecting solder surface height; a rotating member rotatably connected to the support base and fixedly connected to the measuring component; and a driving structure connected to the rotating member, the driving structure being adapted to drive the rotating member to rotate, thereby adjusting the position of the measuring component.

[0006] According to one embodiment of this application, the drive structure includes: a telescopic member, mounted on the support base and connected to the rotating member.

[0007] According to one embodiment of this application, the connection positions of the telescopic member and the rotating member and the connection positions of the measuring component and the rotating member are respectively located on both sides of the connection position between the rotating member and the support base.

[0008] According to one embodiment of this application, the driving structure further includes: a push joint, fixedly connected to the telescopic member; and an adapter shaft, connected to the push joint, wherein the rotating member is provided with a through hole, and the adapter shaft is rotatably inserted through the through hole.

[0009] According to one embodiment of this application, the through hole is a strip-shaped hole provided along the extension direction of the rotating member, and the adapter shaft is adapted to slide along the through hole.

[0010] According to one embodiment of this application, the support base is provided with a groove, and the push joint is slidably disposed in the groove.

[0011] According to one embodiment of this application, the measuring component is detachably connected to the rotating member.

[0012] According to one embodiment of this application, the rotating member includes: a transition portion connecting the support base and the drive structure; a clamping portion forming a gap with the transition portion, the measuring component passing through the gap; and a locking bolt connecting the transition portion and the clamping portion, adapted to adjust the size of the gap between the transition portion and the clamping portion.

[0013] According to one embodiment of this application, the adapter includes a first component and a second component. One end of the first component is connected to the clamping part, and the other end is fixedly connected to one end of the second component. The end of the second component facing away from the first component is connected to the driving structure. The first component and the second component are set at an angle. The contact position of the first component and the second component is rotatably connected to the support base through a rotating shaft.

[0014] According to one embodiment of this application, the measuring component further includes a protective sleeve, which is fitted over the outside of the sensor and fixedly connected to the rotating component.

[0015] The aforementioned solder surface height detection device, by driving the rotating component to rotate relative to the support base via a drive structure, can drive the measuring device to move. The movement path of the measuring device is arc-shaped, including both vertical and horizontal components. Therefore, it can be easily moved above the solder surface for measurement or moved away from the high-temperature area above the solder surface after measurement. The solder surface height detection device of this application does not require multiple cylinders for combined driving, has a simple structure, high execution efficiency, and is beneficial to improving soldering efficiency.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0031] See Figure 1 , Figure 1 This is one perspective view of a solder surface height detection device according to an embodiment of this application. The device includes a support base 100, a measuring component 200, a rotating member 300, and a drive structure 400. The support base 100 supports the measuring component 200, the rotating member 300, and the drive structure 400. The measuring component 200 includes a sensor (not shown) for detecting the solder surface height. The rotating member 300 is rotatably connected to the support base 100 and fixedly connected to the measuring component 200. The drive structure 400 is connected to the rotating member 300 and is adapted to drive the rotating member 300 to rotate, thereby adjusting the position of the measuring component 200.

[0032] In this embodiment, the rotation axis of the rotating component 300 is horizontal, and the driving mechanism is adapted to drive the rotating component 300 to rotate vertically, thereby causing displacement of the measuring component 200. When the driving mechanism drives the rotating component 300 to rotate in one direction, moving the measuring component 200 above the solder surface, the solder surface height can be measured; conversely, when the driving mechanism drives the rotating component 300 to rotate in the opposite direction, moving the measuring component 200 away from the position above the solder surface, damage to the measuring component 200 caused by prolonged exposure to the high-temperature area above the solder surface can be avoided. The solder surface height detection device of this embodiment can simultaneously meet the requirements of lifting and lateral movement through the rotation of the rotating component 300, and its structure is simple and its execution efficiency is high.

[0033] The sensor in this embodiment can be a laser rangefinder, a float sensor, an ultrasonic sensor, etc., and there is no specific limitation here. In other words, any sensor that can measure the height of the tin surface is within the protection scope of this embodiment.

[0034] Combination Figure 2 and Figure 3 In some embodiments, the drive structure 400 includes a telescopic member 410. The telescopic member 410 is mounted on the support base 100 and rotatably connected to the rotating member 300. The connection positions of the telescopic member 410 and the rotating member 300 and the connection positions of the measuring component 200 and the rotating member 300 are respectively located on both sides of the connection position between the rotating member 300 and the support base 100.

[0035] In this embodiment, the telescopic member 410 can drive the rotating member 300 to rotate when it extends or retracts, converting the extension / retraction action of the telescopic member 410 into a rotational action. Thus, only one telescopic structure is needed to simultaneously meet the driving requirements for lifting and lateral movement. Compared to conventional technologies that use multiple cylinders for driving, this method has the advantage of simple structure and ease of implementation. Furthermore, the connection points between the telescopic member 410 and the rotating member 300, and between the measuring component 200 and the rotating member 300, are located on opposite sides of the connection point between the rotating member 300 and the support base 100. This allows the telescopic member 410 to be as far away as possible from the working position of the measuring component 200, avoiding the influence of solder temperature on the telescopic member 410.

[0036] It is worth noting that the drive structure 400 in this embodiment can also adopt other structural forms such as a rotary motor. In other words, any structure that can drive the rotating component 300 to rotate should be within the protection scope of this embodiment.

[0037] Optionally, the telescopic component 410 includes a cylinder, the cylinder barrel of which is connected to the support base 100, and the piston rod of which is connected to the rotating component 300. Of course, the telescopic component 410 can also be a telescopic motor, etc. In this embodiment, a cylinder is used as the driving component, which can utilize existing air supply equipment for driving, offering advantages such as low modification difficulty and low application cost.

[0038] Combination Figure 2 In some embodiments, the drive structure 400 further includes a push joint 420 and an adapter shaft 430. The push joint 420 is fixedly connected to the telescopic member 410, and the adapter shaft 430 is connected to the push joint 420. The rotating member 300 is provided with a through hole 350, and the adapter shaft 430 is rotatably inserted through the through hole 350.

[0039] Specifically, the push joint 420 is provided with a first connecting portion and a second connecting portion parallel to the first connecting portion. A transition groove is formed between the first and second connecting portions. One end of the rotating member 300 has a through hole 350, and the end of the rotating member 300 with the through hole 350 is located within the transition groove. The adapter shaft 430 is connected to both the first and second connecting portions, and the portion of the adapter shaft 430 located between the first and second connecting portions rotatably passes through the through hole 350. The cylinder barrel is connected to the support base 100, and the piston rod of the cylinder is connected to the push joint 420. When the cylinder extends or retracts, it can drive the push joint 420 and the adapter shaft 430 to move, thereby driving the rotating member 300 to rotate vertically.

[0040] In this embodiment, the adapter shaft 430 passes through the through hole 350, thus allowing relative rotation between the rotating member 300, the push joint 420, and the telescopic member 410, accommodating changes in the angle between the telescopic member 410 and the main body and the rotating member 300 during the telescopic movement of the telescopic member 410. Connecting the telescopic member 410 and the rotating member 300 via the push joint 420 and the adapter shaft 430 reduces installation difficulty and increases the stability of the connection between the rotating member 300 and the telescopic member 410.

[0041] In some embodiments, the through hole 350 is an elongated hole and is arranged along the extension direction of the rotating member 300. The adapter shaft 430 is adapted to slide along the through hole 350. When the cylinder extends or retracts, the adapter shaft 430 can slide back and forth along the through hole 350, thereby avoiding the generation of compressive stress between the rotating member 300 and the push joint 420 in a direction perpendicular to the cylinder extension or retraction direction, thus preventing position locking between the rotating member 300 and the push joint 420 and damage to the solder surface height detection device. This embodiment can be applied to a structure in which the cylinder barrel is fixed to the support base 100. Fixing the cylinder barrel to the support base 100 can make the operation of the solder surface height detection device more stable and facilitate the arrangement of the air passage.

[0042] Of course, in some other embodiments, the cylinder barrel and the support base 100 and the push joint 420 and the rotating part 300 can be hinged, which can also drive the rotating part 300 to rotate through the cylinder.

[0043] Combination Figure 4Optionally, the support base 100 is provided with a groove 110, the extension direction of which is parallel to the extension direction of the telescopic member 410. For example, if the telescopic member 410 is arranged vertically, that is, the extension direction of the telescopic member 410 is vertical, then the groove 110 extends vertically. The push joint 420 is slidably disposed within the groove 110. The groove 110 prevents the push joint 420 from displacing perpendicular to the extension direction of the telescopic member 410, making the movement of the push structure more stable and improving transmission efficiency.

[0044] See you later Figure 2 and Figure 3 In some embodiments, the measuring component 200 is detachably connected to the rotating component 300. Therefore, when the measuring component 200 malfunctions, it can be easily removed for repair or replacement.

[0045] In some embodiments, the rotating member 300 includes a transition portion 310, a clamping portion 320, and a locking bolt 330. The transition portion 310 connects the support base 100 and the drive structure 400. A gap 340 is formed between the clamping portion 320 and the transition portion 310, and the measuring component 200 is located within the gap 340. The locking bolt 330 connects the transition portion 310 and the clamping portion 320 and is adapted to adjust the size of the gap 340 between the transition portion 310 and the clamping portion 320.

[0046] Specifically, the locking bolt 330 is engaged with one of the clamping portion 320 and the adapter portion 310, and is threadedly connected to the other of the clamping portion 320 and the adapter portion 310. For example, the locking bolt 330 passes through the clamping portion 320 and is threadedly connected to the adapter portion 310. The head of the locking bolt 330 is located on the side of the clamping portion 320 away from the adapter portion 310. When the locking bolt 330 is rotated, the distance between the head of the locking bolt 330 and the adapter portion 310 changes, thereby adjusting the size of the gap between the clamping portion 320 and the adapter portion 310. When the distance between the head of the locking bolt 330 and the adapter 310 decreases, the gap 340 between the clamping part 320 and the adapter 310 can be reduced, thereby locking the measuring component 200. When the distance between the head of the locking bolt 330 and the adapter 310 increases, the gap 340 between the clamping part 320 and the adapter 310 can be increased accordingly, making it easier to remove the measuring component 200.

[0047] The rotating component 300 of the above structure has the advantage of being easy to connect with the measuring component 200. Furthermore, the installation height of the measuring component 200 can be adjusted by adjusting the relative position between the measuring component 200 and the rotating component 300, making it compatible with various solder surface height detection methods and expanding its application range.

[0048] Optionally, one end of the adapter 310 is fixedly connected to the same-direction end of the clamping part 320. When adjusting the size of the gap 340 between the adapter 310 and the clamping part 320 using the locking bolt 330, the relative position between the connected ends of the adapter 310 and the clamping part 320 remains unchanged, while the other end of the clamping part 320 moves closer to or further away from the adapter 310. This structure reduces the difficulty of adjusting the gap 340 between the adapter 310 and the clamping part 320, which can be accomplished with just one locking bolt 330. Furthermore, the stable relative position between the clamping part 320 and the adapter 310 allows for a more secure fixation of the measuring assembly 200. In addition, it prevents the rotating part from completely disengaging from the clamping part 320 and being lost.

[0049] Optionally, the adapter 310 and the clamping part 320 are integrally formed. For example, the adapter 310 and the clamping part 320 are integrally cast, and the adapter 310 and the clamping part 320 are formed by machining a gap 340. This can increase the connection strength between the adapter 310 and the clamping part 320, improve the stability of clamping, and help reduce the difficulty of production.

[0050] Optionally, the adapter 310 is provided with a notch, and the clamping part 320 is located at the notch, thereby reducing the overall volume of the adapter 310 and the clamping part 320.

[0051] Of course, the rotating part 300 and the measuring component 200 can also be detachably connected by means of snap-fit, etc., which will not be listed here.

[0052] In some embodiments, the adapter 310 includes a first component 311 and a second component 312. One end of the first component 311 is connected to the clamping part 320, and the other end is fixedly connected to the second component 312. One end of the second component 312 away from the first component 311 is connected to the drive structure 400. The first component 311 and the second component 312 are arranged at an angle. The contact position of the first component 311 and the second component 312 is rotatably connected to the support base 100 through a rotating shaft.

[0053] Specifically, both the first component 311 and the second component 312 are strip-shaped structures. The cross-sectional shape of the first component 311 and the second component 312 can be circular, rectangular, or polygonal, etc., without specific limitation. The included angle between the first component 311 and the second component 312 is greater than 90° and less than 180°. For example, the included angle between the first component 311 and the second component 312 is 120°. The included angle between the first component 311 and the second component 312 faces upward. A through hole is provided at the connection position of the first component 311 and the second component 312. The rotating shaft passes through the through hole and is fixedly connected to the support base 100. The end of the first component 311 facing away from the second component 312 is fixedly connected to the clamping part 320, and the end of the second component 312 facing away from the first component 311 is rotatably connected to the push joint 420. When the telescopic member 410 is extended to its maximum length, the first component 311 is horizontal, and the measuring component 200 is located in the high-temperature area above the solder surface, which can detect the height of the solder surface; when the telescopic member 410 is shortened to its minimum length, the first component 311 is vertical and moves away from the high-temperature area above the solder surface, so as to prevent the measuring component 200 from being damaged by being placed in the high-temperature area for a long time.

[0054] In this embodiment, by setting the first component 311 and the second component 312 at an angle, the measuring component 200 can be guaranteed to have a sufficient angle adjustment range. Furthermore, locking can be avoided. Specifically, when the first component 311 is in a vertical position, the second component 312 forms an angle with the telescopic member 410, preventing the force exerted on the second component 312 by the telescopic member 410 when it extends from being along the extension direction of the second component 312, thereby preventing locking.

[0055] Optionally, the first component 311 and the second component 312 are integrally formed, which helps to improve the structural strength of the transition part 310 and reduce the processing difficulty of the transition part 310.

[0056] In some embodiments, the measuring component 200 further includes a protective sleeve, which is fitted over the outside of the sensor and fixedly connected to the rotating component 300. The protective sleeve can be made of high-temperature resistant materials such as metal or ceramic, thereby protecting the sensor, extending the service life of the tin surface height detection device, and reducing production costs.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
