[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0039] In the related art, when the components on the circuit board are soldered to the substrate, processing defects such as cold soldering, leaking soldering or desoldering are likely to occur, resulting in poor quality assurance of the finished circuit board. Therefore, there is an urgent need for a circuit board inspection device to inspect the soldering conditions of the substrate and components of the circuit board after the components on the circuit board are soldered to the substrate.
[0040] However, in the circuit board detection equipment in the prior art, a guide assembly is provided on the upper surface of the frame, and the mounting beam for mounting the detection assembly is movably connected to the frame through the guide assembly, so as to realize the relative movement of the mounting beam and the frame, so that the detection assembly can be moved to the position of the circuit board to be detected to detect the circuit board to be detected. However, it is found in the actual detection process that when the detection assembly moves on the mounting beam, there is an angle between the moving direction and the extension direction of the guide assembly (for example, the two are vertically arranged), which will cause the detection assembly to be pulled on the guide assembly when it moves on the mounting beam, causing the slide rail in the guide assembly to deform, so that the guide assembly cannot provide a certain connection strength in the moving direction of the detection assembly on the mounting beam, and finally when the detection assembly moves, the inertial force generated by it will cause the frame to shake, and then cause the circuit board detection equipment to shake as a whole, and when the circuit board detection equipment shakes as a whole, the detection assembly will shake accordingly, which will cause the detection equipment to have poor accuracy when detecting the circuit board to be detected, affecting the final detection effect, and it is impossible to accurately detect the welding situation on the circuit board.
[0041] To solve the above problems, please refer to Figures 1 to 3 The present application proposes a circuit board detection device 100. In the embodiment of the present application, the detection device includes a frame 10 and a bearing assembly 30, a detection device 50, a first driving member (not shown in the figure), a guide device 60, a second driving member (not shown in the figure), a third guide assembly 70, a supporting foot cup 80 and a suction cup 90 arranged on the frame 10. The bearing assembly 30 is used to carry a circuit board to be detected (not shown in the figure), and the detection device 50 is used to detect the circuit board to be detected.
[0042] The circuit board to be tested can be a board of a television, or a circuit board on other electronic devices, such as mobile phones, computers, and other electronic devices. Specifically, the purpose of the detection device 50 can be to detect the welding conditions between the substrate and the components in the circuit board to be tested, such as detecting whether there are cold solder joints, leaking solder joints, over-soldering or desoldering between the two, so as to judge the welding quality of the circuit board to be tested. Of course, the purpose of the detection device 50 can also be to detect whether the circuit board to be tested has appearance defects, etc., which is not limited to this.
[0043] The structure of the frame 10 can be in the form of a frame, and mainly plays the role of supporting various components in the detection device (including but not limited to the supporting assembly 30, the detection device 50, the first driving member, the guide device 60, the second driving member, and the third guide assembly 70). The frame 10 may include a base and two support frames 11, the two support frames 11 are arranged at opposite sides of the base, and the support frames 11 and the base can be fixedly connected by welding to ensure the strength of the frame 10.
[0044] The bearing assembly 30 is connected to the support frame 11 of the frame 10, and a bearing space is formed, which is used to bear the circuit board to be detected, to ensure the placement stability of the circuit board to be detected during the detection process, and to enable the detection device 50 to detect the circuit board to be detected through the bearing space. In this way, the installation space of the frame 10 can also be used to install the bearing assembly 30, so that the circuit board detection device 100 has a higher degree of integration. Of course, the circuit board to be detected can also be detected by a bearing structure outside the circuit board detection device 100, which is not limited to this.
[0045] The detection device 50 may include a mounting beam 51 and a detection component 53 disposed on the mounting beam 51. The detection component 53 may include a housing 531 and a lens (not shown in the figure), a projector (not shown in the figure), and a light source (not shown in the figure) installed in the housing 531.
[0046] See also Figure 4 The mounting beam 51 is movably connected to the support frame 11 of the frame 10. For example, the mounting beam 51 can slide back and forth along the support frame 11 of the frame 10 in the x direction. That is, when the first driving member is drivingly connected to the mounting beam 51 and the mounting beam 51 and the frame 10 are slidably connected via the guide device 60, the mounting beam 51 can slide relative to the frame 10 under the driving of the first driving member. The first driving member can be in the form of a motor, and the motor has an output shaft, which is drivingly connected to the brush head mounting beam 51.
[0047] The guide device 60 includes a first guide component 61 and a second guide component 63, that is, the mounting beam 51 can be slidably connected to the support frame 11 of the frame 10 through the first guide component 61 and the second guide component 63. In this way, the first guide component 61 and the second guide component 63 can increase the connection area between the mounting beam 51 and the support frame 11 of the frame 10, and improve the connection stiffness between the mounting beam 51 and the support frame 11 of the frame 10 without affecting the sliding of the mounting beam 51, so that the vibration of the detection component 53 to the frame 10 during the movement can be reduced, thereby reducing the overall shaking of the circuit board detection device 100, improving the detection accuracy of the detection component 53, and the first guide component 61 and the second guide component 63 can also improve the accuracy and stability of the movement of the mounting beam 51 in the x direction.
[0048] Further, the first guide assembly 61 and the second guide assembly 63 are respectively arranged on two adjacent surfaces of the support frame 11 of the frame 10. When the detection assembly 53 slides relative to the mounting beam 51, a shaking force will be given to the mounting beam 51 in the sliding direction, and the shaking force will be transmitted to the first guide assembly 61, so that the guide rail of the first guide assembly 61 is deformed, affecting the anti-sway force given to the mounting beam 51 by the first guide assembly 61, resulting in the frame 10 vibrating and shaking more. Therefore, compared with the form in which the first guide assembly 61 and the second guide assembly 63 are both arranged on the same surface of the support frame 11 of the frame 10, the solution of the present application arranges the first guide assembly 61 and the second guide assembly 63 on two adjacent surfaces of the support frame 11 of the frame 10, which can avoid deformation of both the first guide assembly 61 and the second guide assembly 63, so that the first guide assembly 61 and the second guide assembly 63 can better ensure the anti-sway force given to the mounting beam 51 by the first guide assembly 61 and the second guide assembly 63, and avoid the frame 10 from shaking more under the movement of the detection assembly 53.
[0049] The housing 531 of the detection component 53 is movably connected to the mounting beam 51, for example, the housing 531 of the detection component 53 can slide back and forth along the mounting beam 51 in the y direction, that is, when the second driving member is installed on the mounting beam 51 and is transmission-connected to the housing 531 of the detection component 53, and the housing 531 of the detection component 53 and the mounting beam 51 are slidably connected via the third guide assembly 70, under the drive of the second driving member, the housing 531 of the detection component 53 can slide relative to the mounting beam 51, so that the lens of the detection component 53 is used to detect the circuit board to be detected on the bearing assembly 30. The second driving member can be in the form of a motor, and the motor has an output shaft, which is transmission-connected to the brush head mounting beam 51.
[0050] Please refer to Figures 5 and 6The support foot cup 80 may include a support body 81 and a suction cup portion 83, wherein the support body 81 is connected to the bottom of the frame 10, that is, connected to the side of the base away from the support frame 11, wherein the support body 81 is used to abut against the installation environment, and the installation environment may be an installation plane (for example, it may be an installation plane in the inspection workshop) to support the frame 10. Part of the structure of the suction cup portion 83 is installed inside the support body 81, and another part of the structure is passed through the support body 81 for adsorbing the installation environment. With this arrangement, the adsorption force of the suction cup portion 83 can make the connection between the support foot cup 80 and the installation environment more secure, reduce the overall shaking of the circuit board inspection device 100, and improve the inspection accuracy of the inspection component 53.
[0051] In the exemplary solution shown in the figure, the present application sets the number of supporting foot cups 80 to be multiple, for example, when the number is four, the four supporting foot cups 80 are arranged at intervals along the circumference of the frame 10, and can be set at the four corners of the base of the frame 10 to improve the overall stability of the supporting foot cups 80 supporting the frame 10. Of course, the number of supporting foot cups 80 can be two, six, or eight, etc., and this is not limited.
[0052] The suction cup 90 is connected to the bottom of the base of the rack 10, and the number of the suction cups 90 can be multiple, and the multiple suction cups 90 are arranged at intervals along the circumference of the rack 10. In this way, the multiple suction cups 90 adsorb the installation environment to generate adsorption force, so that the connection between the rack 10 and the installation environment is further strengthened, thereby further reducing the overall shaking of the circuit board detection device 100 and improving the detection accuracy of the detection component 53. In the structure exemplarily shown in the figure, a suction cup 90 is provided between two adjacent supporting foot cups 80, so that the installation space of the base of the rack 10 can be used more reasonably, and the overall stability effect of supporting the rack 10 can be guaranteed.
[0053] The technical solution of the present application adopts a sliding connection between the mounting beam 51 and the frame 10 through the first guide component 61 and the second guide component 63, and the first guide component 61 and the second guide component 63 are respectively arranged on two adjacent surfaces of the frame 10. In the actual working process, without affecting the sliding of the mounting beam 51 and the frame 10, on the basis of the surface of the frame 10 provided with the first guide component 61, the second guide component 63 is added to the adjacent surface of the surface to increase the contact area between the mounting beam 51 and the frame 10, and improve the connection rigidity between the two. In this way, when the detection device 50 reciprocates along the mounting beam 51, the vibration of the mounting beam 51 and the frame 10 is reduced, so as to reduce the overall vibration of the circuit board detection device 100, so that the detection device 50 can remain stable during the detection process, and the detection accuracy of the circuit board to be detected is improved.
[0054] In one embodiment, please refer to Figure 1 to Figure 2 , two support frames 11 are arranged on opposite sides of the mounting beam 51. In this way, by arranging the two support frames 11 on opposite sides of the mounting beam 51, the overall support stability of the mounting beam 51 is improved. Each support frame 11 includes two support beams 113 and a crossbeam 111 connected between the two support beams 113, the crossbeam 111 includes an adjacent top surface 1111 and a side surface 1113, the side surface 1113 faces the other support frame 11, the first guide assembly 61 is arranged on the top surface 1111, and the second guide assembly 63 is arranged on the side surface 1113. In this way, the support installation of the first guide assembly 61 and the second guide assembly 63 is respectively realized by the top surface 1111 and the side surface 1113 of the crossbeam 111, that is, the contact area between the mounting beam 51 and the crossbeam 111 of the support frame 11 of the frame 10 is increased by the first guide assembly 61 and the second guide assembly 63, and the connection stiffness between the mounting beam 51 and the crossbeam 111 of the support frame 11 of the frame 10 is improved. At the same time, the first guide component 61 is arranged on the top surface 1111. When the second guide component 63 is arranged on the side surface 1113 (that is, the inner side of the crossbeam 111 of the support frame 11), the overall installation space of the crossbeam 111 can be more reasonably utilized to install and arrange the first guide component 61 and the second guide component 63. The first guide component 61 and the second guide component 63 can be installed without increasing the volume of the crossbeam 111 itself. In this way, while ensuring the connection stiffness between the mounting beam 51 and the crossbeam 111 of the support frame 11 of the frame 10, the material consumption of the crossbeam 111 can be reduced, thereby reducing the production cost of the workshop.
[0055] Of course, the second guide assembly 63 may also be arranged on the outer side surface of the beam 111 (that is, the outer side surface opposite to the inner side surface of the beam 111 of the support frame 11), or the first guide assembly 61 and the second guide assembly 63 may be distributed on adjacent surfaces of the beam 111. In the present application, the second guide assembly 63 is arranged on the outer side surface of the beam 111. Compared with the second guide assembly 63 being arranged on the inner side surface of the beam 111, the mounting beam 51 does not need to be extended to the position of the outer side surface of the beam 111 to achieve connection with the second guide assembly 63. In this way, the material of the mounting beam 51 can be saved while reducing the overall volume of the circuit board detection device 100.
[0056] In the scheme exemplified in the figure, the present application sets the number of detection devices 50 to at least two, that is, for some types of circuit boards to be detected, both the upper and lower surfaces of the circuit boards themselves can be welded to components, so it is necessary to set up two detection devices 50 for detecting the circuit boards to be detected. In this way, there is no need to detect the other surface after completing the detection of one surface of the circuit board to be detected, so that synchronous detection can be achieved and the detection efficiency is improved.
[0057] In order to ensure the detection accuracy of at least two detection devices 50, the number of beams 111 and guide devices 60 is also at least two, and at least two beams 111 are arranged at intervals along the height direction of the support beam 113, and one detection device 50 corresponds to one beam 111 and one guide device 60 is set.
[0058] In one structural form, please refer to Figure 4 The mounting beam 51 includes a main body 511 and a first connection portion 515 and a second connection portion 513 connected to the main body 511. The first connection portion 515 is slidably connected to the top surface 1111 through the first guide assembly 61, and the second connection portion 513 is slidably connected to the side surface 1113 through the second guide assembly 63. The first connection portion 515 and the second connection portion 513 slide with the top surface 1111 and the side surface 1113 respectively, so that the main body 511 can slide back and forth along the frame 10. There is no need to enlarge the main body 511 of the mounting beam 51. The main body 511 can be connected to the crossbeam 111 of the support frame 11 through the first connection portion 515 and the second connection portion 513 respectively.
[0059] Furthermore, the main body 511 of the mounting beam 51 is provided with a plurality of material reduction holes 5111, and the plurality of material reduction holes 5111 are arranged at intervals along the width direction of the mounting beam 51. In this way, the weight of the main body 511 of the mounting beam 51 can be reduced through the material reduction holes 5111, and the overall vibration of the circuit board detection device 100 can be reduced while ensuring the connection stiffness between the first connection part 515 of the mounting beam 51 and the second connection part 513 and the frame 10. Specifically, the number of material reduction holes 5111 can be two, three or four, etc. Of course, when the area of a single material reduction hole 5111 is large enough and can meet the requirement of reducing the gravity of the main body 511 of the mounting beam 51, the number of material reduction holes 5111 can also be one, and there is no limitation on this.
[0060] In one embodiment, please refer to Figure 2The first guide assembly 61 includes at least two first sliders 611 and a first slide rail 613 extending in the direction in which the mounting beam 51 slides along the frame 10. The at least two first sliders 611 are slidably connected to the first slide rail 613, and in the direction in which the mounting beam 51 slides along the frame 10, the at least two first sliders 611 are respectively connected to opposite sides of the first connecting portion 515. Through the sliding cooperation between the first slider 611 and the first slide rail 613, the sliding connection of the first connecting portion 515 of the mounting beam 51 can be achieved, and by setting the number of the first sliders 611 to at least two, the contact area between the first connecting portion 515 of the mounting beam 51 and the first slide rail 613 can be increased by the at least two first sliders 611, so that the connection rigidity between the mounting beam 51 and the frame 10 can be further improved.
[0061] The second guide assembly 63 includes at least two second sliders 631 and a second slide rail 633 extending in the direction in which the mounting beam 51 slides along the frame 10. The at least two second sliders 631 are slidably connected to the second slide rail 633, and in the direction in which the mounting beam 51 slides along the frame 10, the at least two second sliders 631 are respectively connected to opposite sides of the second connection portion 513. Through the sliding cooperation between the second sliders 631 and the second slide rail 633, the sliding connection of the second connection portion 513 of the mounting beam 51 can be achieved, and by setting the number of the second sliders 631 to at least two, the contact area between the second connection portion 513 of the mounting beam 51 and the second slide rail 633 can be increased by the at least two second sliders 631, so that the connection rigidity between the mounting beam 51 and the frame 10 can be further improved.
[0062] In the exemplary solution shown in the figure, the present application provides at least two third guide assemblies 70, and at least two third guide assemblies 70 are arranged at intervals along the height direction of the mounting beam 51. In this way, the connection stability between the housing 531 of the detection assembly 53 and the mounting beam 51 is improved by at least two third guide assemblies 70.
[0063] Specifically, the third guide assembly 70 includes a third slider 71 and a third slide rail 73 slidably connected to the third slider 71, the third slide rail 73 extends in the direction in which the detection assembly 53 slides along the mounting beam 51, the third slider 71 is connected to the housing 531 of the detection assembly 53, and the third slide rail 73 is connected to the main body 511 of the mounting beam 51. In addition, the number of the third sliders 71 may be at least two, and at least two third sliders 71 are connected to opposite sides of the housing 531 of the detection assembly 53 to increase the connection area between the housing 531 of the detection assembly 53 and the main body 511 of the mounting beam 51.
[0064] The above content introduces the advantages of the circuit board detection device 100 of the present application, which has stable operation and is not easy to shake, from the aspect of the setting form of the guide device 60. On this basis, in order to improve the versatility of the circuit board detection device 100 for detecting the circuit board to be detected, the present application can also be that the bearing assembly 30 can include two bearing racks 31 arranged at intervals, and the above-mentioned bearing space is formed between the two bearing racks 31, so that the two bearing racks 31 can jointly carry the circuit board to be detected. The distance between the two bearing racks 31 is adjustable, so that the distance between the two bearing racks 31 can be adjusted for suitability according to the circuit boards to be detected of different sizes for matching, so that the circuit board detection device 100 of the present application has higher versatility.
[0065] Specifically, the distance adjustment method between the two carriers 31 can be: the two carriers 31 are connected by a threaded screw, and the threads of the connection between the two carriers 31 and the threaded screw are opposite, and the threaded screw is driven by a motor to rotate forward or reverse, so that the two carriers 31 can be moved closer or farther away from each other, so as to adjust the distance between the two carriers 31. Of course, the bearing assembly 30 can also be separately set as an integral frame structure, that is, the two carriers 31 are in an integral form, so that the number of structures can be simplified. Of course, the distance adjustment method between the two carriers 31 can also be other automatic adjustment methods, or can be adjusted manually, which is not limited.
[0066] In one structural form, the supporting assembly 30 may also include a conveying track (not shown in the figure), which is installed on the surface of the supporting frame 31, so that after the previous process (such as the welding process of the substrate and components) is completed, the circuit board to be inspected is automatically transported through the conveying track. In this way, the degree of automation of the circuit board inspection equipment 100 can be improved, and manual transportation is no longer required, thereby improving the inspection efficiency.
[0067] It can be understood that in the exemplary detection process of the circuit board detection device 100, it can be: first, according to the size of the circuit board to be detected that is actually required to be tested, the distance between the two carriers 31 of the supporting component 30 is adjusted to match the size of the circuit board to be detected that is required to be tested at this time, and then the circuit board to be detected is automatically transported from the previous process through the conveying track and transported to the two carriers 31 of the supporting component 30. At this time, the position where the circuit board to be detected on the two carriers 31 of the supporting component 30 can be a preset stop position, or a random position on the two carriers 31. Then, the position of the circuit board to be detected is identified by an additional identification device of the circuit board detection device 100, such as a CCD device, and then the mounting beam 51 can be driven to move in the x direction and the detection device 50 can be driven to move in the y direction, so that the detection device 50 can move to the position of the circuit board to be detected for detection. After the detection is completed, the conveying track can be used to automatically transport the circuit board to the next process after the detection.
