技术领域Technical Field
本实用新型涉及电路板测试领域，具体涉及一种电路板多接点测试装置。The utility model relates to the field of circuit board testing, in particular to a circuit board multi-contact testing device.
背景技术Background technique
电路板的名称有：陶瓷电路板，氧化铝陶瓷电路板，氮化铝陶瓷电路板，线路板，PCB板，铝基板，高频板，厚铜板，阻抗板，PCB，超薄线路板，超薄电路板，印刷电路板等，电路板使电路迷你化、直观化，对于固定电路的批量生产和优化用电器布局起重要作用。The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum base board, high-frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances.
目前电路板在正式安装前需要经过测试才能使用，传统的电路板接点测试都是率先将电路板夹持固定，然后再通过探针对电路板进行测试，然而电路板在测试的过程中，探针都是被气缸或电动推杆驱动直接下移接触到电路板的表面，这时探针很容易挤压或撞击电路板造成其表面受损，从而造成电路板无法正常使用。Currently, circuit boards need to be tested before they can be used before they are officially installed. Traditional circuit board contact tests first clamp the circuit board and then test it with a probe. However, during the circuit board test, the probe is driven by a cylinder or an electric push rod to move directly down and contact the surface of the circuit board. At this time, the probe can easily squeeze or hit the circuit board, causing damage to its surface, thereby causing the circuit board to be unable to be used normally.
因此，发明一种电路板多接点测试装置很有必要。Therefore, it is necessary to invent a circuit board multi-contact testing device.
实用新型内容Utility Model Content
本实用新型的目的是为解决上述背景技术中提出的问题。The purpose of the utility model is to solve the problems raised in the above background technology.
为了实现上述目的，本实用新型提供如下技术方案：一种电路板多接点测试装置，包括支撑板，所述支撑板的下方设置有移动板，所述支撑板的上端安装有电动推杆，所述移动板的下端安装有固定套筒，所述固定套筒的下端连接有探针，所述支撑板的一侧设置有调节组件，所述调节组件上端两侧对称安装有夹持组件，所述夹持组件位于探针下方；In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circuit board multi-contact testing device, comprising a support plate, a movable plate is arranged below the support plate, an electric push rod is installed on the upper end of the support plate, a fixed sleeve is installed on the lower end of the movable plate, a probe is connected to the lower end of the fixed sleeve, an adjustment component is arranged on one side of the support plate, clamping components are symmetrically installed on both sides of the upper end of the adjustment component, and the clamping component is located below the probe;
所述夹持组件包括固定板以及所述固定板上端安装的安装框，所述安装框中间安装有滚轮；The clamping assembly includes a fixing plate and a mounting frame installed on the upper end of the fixing plate, and a roller is installed in the middle of the mounting frame;
所述固定板的下端固定安装有滑动块，所述滑动块与导向槽滑动连接，所述固定板的中间安装有活动螺母，所述活动螺母与正反螺杆螺纹连接；A sliding block is fixedly installed at the lower end of the fixed plate, and the sliding block is slidably connected with the guide groove. A movable nut is installed in the middle of the fixed plate, and the movable nut is threadedly connected with the forward and reverse screws;
所述滚轮的中间安装有中心轴，所述中心轴的两端安装有转轴，所述滚轮的外表面开设有环形结构的限位槽，所述限位槽的两端表面安装有橡胶圈。A central shaft is installed in the middle of the roller, rotating shafts are installed at both ends of the central shaft, and a limiting groove with an annular structure is opened on the outer surface of the roller, and rubber rings are installed on the surfaces of both ends of the limiting groove.
基于上述特征：调节组件可以调节夹持组件之间的间距，随后将电路板从夹持组件的一侧穿入，使夹持组件对电路板的两侧限位固定，接着通过电动推杆带动移动板下移，而移动板将同步带动固定套筒和探针向下移动，使探针与电路板相接触，由于探针设置为多个，从而可以对多个接点进行测试，增加了测试效率。滚轮转动连接在安装框内部，固定板通过活动螺母与正反螺杆螺纹连接，当正反螺杆带动夹持组件呈对向或反向移动时，固定板可以通过安装框带动滚轮同步移动，当电路板插入两个对称的滚轮中间时，电路板的两侧将限位在限位槽内侧，同时随着电路板的移动，滚轮也可以发生旋转滚动，辅助电路板快速插入和抽出。Based on the above features: the adjustment component can adjust the spacing between the clamping components, and then the circuit board is inserted from one side of the clamping component so that the clamping component can limit and fix the two sides of the circuit board. Then the electric push rod drives the moving plate to move downward, and the moving plate will synchronously drive the fixed sleeve and the probe to move downward so that the probe contacts the circuit board. Since the probes are set in multiples, multiple contacts can be tested, which increases the test efficiency. The roller is rotatably connected inside the installation frame, and the fixed plate is threadedly connected to the forward and reverse screws through the movable nut. When the forward and reverse screws drive the clamping components to move in opposite or reverse directions, the fixed plate can drive the roller to move synchronously through the installation frame. When the circuit board is inserted between the two symmetrical rollers, the two sides of the circuit board will be limited inside the limit groove. At the same time, as the circuit board moves, the roller can also rotate and roll to assist the circuit board in rapid insertion and extraction.
优选的，所述探针的上端安装有挡板，所述挡板上端安装有缓冲弹簧，所述挡板与缓冲弹簧位于固定套筒内部。Preferably, a baffle is installed at the upper end of the probe, a buffer spring is installed at the upper end of the baffle, and the baffle and the buffer spring are located inside the fixed sleeve.
基于上述特征：当探针下移接触电路板时，探针将通过挡板挤压固定套筒内部的缓冲弹簧进行缓冲，避免探针下压时冲击力过大造成电路板表面受损，而由于挡板在探针的上方限位，使得探针不会自行与固定套筒产生分离。Based on the above characteristics: when the probe moves down and contacts the circuit board, the probe will be buffered by squeezing the buffer spring inside the fixed sleeve through the baffle plate, so as to avoid damage to the circuit board surface due to excessive impact force when the probe is pressed down. Since the baffle plate is limited above the probe, the probe will not separate from the fixed sleeve by itself.
优选的，所述调节组件包括固定架以及所述固定架中间安装的正反螺杆，所述正反螺杆的一端安装有驱动轴，所述驱动轴的另一端连接有驱动电机。Preferably, the adjustment assembly includes a fixing frame and a forward and reverse screw installed in the middle of the fixing frame, a driving shaft is installed at one end of the forward and reverse screw, and a driving motor is connected to the other end of the driving shaft.
基于上述特征：驱动电机可以通过驱动轴带动正反螺杆正反转调节，使正反螺杆可以带动夹持组件呈对向或反向移动调节。Based on the above characteristics: the driving motor can drive the forward and reverse screws to adjust forward and reverse through the driving shaft, so that the forward and reverse screws can drive the clamping components to move in opposite or reverse directions.
优选的，所述固定架的底面中间开设有导向槽，所述固定架远离驱动电机的一端安装有轴承座。Preferably, a guide groove is provided in the middle of the bottom surface of the fixing frame, and a bearing seat is installed at one end of the fixing frame away from the driving motor.
基于上述特征：正反螺杆的一端与驱动轴连接，另一端则与轴承座连接固定，并且设置的导向槽可以在夹持组件的下方进行限位，使夹持组件保持平移，不会跟随正反螺杆发生转动。Based on the above features: one end of the forward and reverse screw is connected to the drive shaft, and the other end is fixedly connected to the bearing seat, and the guide groove provided can limit the position below the clamping assembly, so that the clamping assembly maintains translation and does not rotate with the forward and reverse screw.
本实用新型的有益效果是：The beneficial effects of the utility model are:
1、当电路板需要测试时，根据电路板的宽度提前调节好两个滚轮之间的间距，调节时，驱动电机可以通过驱动轴带动正反螺杆正反转调节，固定板通过活动螺母与正反螺杆螺纹连接，使得活动螺母可以带动固定板同步移动，而当固定板移动时，可以通过安装框带动滚轮移动，当两个滚轮之间的间距调节完成后，可以将电路板插入两个对称的滚轮中间，此时电路板的两侧将限位在限位槽内侧，随着电路板的移动，滚轮也可以发生旋转滚动，辅助电路板快速插入和抽出。1. When the circuit board needs to be tested, the spacing between the two rollers is adjusted in advance according to the width of the circuit board. During adjustment, the drive motor can drive the forward and reverse screws to adjust forward and reverse through the drive shaft. The fixed plate is threadedly connected to the forward and reverse screws through the movable nut, so that the movable nut can drive the fixed plate to move synchronously. When the fixed plate moves, the roller can be driven to move through the mounting frame. When the spacing between the two rollers is adjusted, the circuit board can be inserted between the two symmetrical rollers.

When the circuit board is fixed in position, the electric push rod will drive the movable plate to move downward, and the movable plate will also synchronously drive the fixed sleeve and the probe to move downward, so that the probe contacts the circuit board. When the probe moves downward and contacts the circuit board, the probe will squeeze the buffer spring inside the fixed sleeve through the baffle to buffer, so as to avoid damage to the circuit board surface due to excessive impact force when the probe is pressed down. Since multiple probes are set, multiple contacts can be tested, which increases the test efficiency.

具体实施方式Detailed ways
以下结合附图对本实用新型的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本实用新型，并不用于限定本实用新型。The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
参照附图1-4，本实用新型提供的一种电路板多接点测试装置，包括支撑板1，支撑板1的下方设置有移动板2，支撑板1的上端安装有电动推杆3，移动板2的下端安装有固定套筒4(固定套筒4为上端密封下端开口状，且固定套筒4内部为中考结构)，固定套筒4的下端连接有探针5(固定套筒4和探针5设置为多个，二者呈矩形阵列状分布在移动板2下方)，支撑板1的一侧设置有调节组件6，调节组件6上端两侧对称安装有夹持组件7，夹持组件7位于探针5下方；Referring to Figures 1-4, a circuit board multi-contact testing device provided by the utility model comprises a supporting plate 1, a moving plate 2 is arranged below the supporting plate 1, an electric push rod 3 is installed on the upper end of the supporting plate 1, a fixed sleeve 4 is installed on the lower end of the moving plate 2 (the fixed sleeve 4 is sealed at the upper end and open at the lower end, and the interior of the fixed sleeve 4 is a test structure), a probe 5 is connected to the lower end of the fixed sleeve 4 (the fixed sleeve 4 and the probe 5 are arranged in plurality, and the two are distributed in a rectangular array below the moving plate 2), an adjusting component 6 is arranged on one side of the supporting plate 1, and clamping components 7 are symmetrically installed on both sides of the upper end of the adjusting component 6, and the clamping component 7 is located below the probe 5;
进一步地，夹持组件7包括固定板71以及固定板71上端安装的安装框72，安装框72中间安装有滚轮73；Furthermore, the clamping assembly 7 includes a fixing plate 71 and a mounting frame 72 mounted on the upper end of the fixing plate 71, and a roller 73 is mounted in the middle of the mounting frame 72;
进一步地，固定板71的下端固定安装有滑动块711，滑动块711与导向槽611滑动连接(当固定板71移动时，滑动块711将在导向槽611内部限位滑动，使固定板71移动时保持平移)，固定板71的中间安装有活动螺母712，活动螺母712与正反螺杆62螺纹连接；Furthermore, a sliding block 711 is fixedly installed at the lower end of the fixed plate 71, and the sliding block 711 is slidably connected with the guide groove 611 (when the fixed plate 71 moves, the sliding block 711 will slide within the guide groove 611 to keep the fixed plate 71 moving in translation), and a movable nut 712 is installed in the middle of the fixed plate 71, and the movable nut 712 is threadedly connected with the forward and reverse screws 62;
进一步地，滚轮73的中间安装有中心轴731，中心轴731的两端安装有转轴732，滚轮73的外表面开设有环形结构的限位槽733，限位槽733的两端表面安装有橡胶圈734。Furthermore, a central shaft 731 is installed in the middle of the roller 73, and rotating shafts 732 are installed at both ends of the central shaft 731. The outer surface of the roller 73 is provided with a ring-shaped limiting groove 733, and rubber rings 734 are installed on the surfaces of both ends of the limiting groove 733.
调节组件6可以调节夹持组件7之间的间距，随后将电路板从夹持组件7的一侧穿入，使夹持组件7对电路板的两侧限位固定，接着通过电动推杆3带动移动板2下移，而移动板2将同步带动固定套筒4和探针5向下移动，使探针5与电路板相接触，由于探针5设置为多个，从而可以对多个接点进行测试，增加了测试效率。The adjusting component 6 can adjust the spacing between the clamping components 7, and then the circuit board is inserted from one side of the clamping component 7 so that the clamping component 7 can limit and fix the two sides of the circuit board. Then the movable plate 2 is driven downward by the electric push rod 3, and the movable plate 2 will synchronously drive the fixed sleeve 4 and the probe 5 to move downward so that the probe 5 contacts the circuit board. Since there are multiple probes 5, multiple contacts can be tested, which increases the test efficiency.
滚轮73转动连接在安装框72内部，固定板71通过活动螺母712与正反螺杆62螺纹连接，当正反螺杆62带动夹持组件7呈对向或反向移动时，固定板71可以通过安装框72带动滚轮73同步移动，使滚轮73可以在电路板的两侧限位夹持。滚轮73套装在中心轴731的外部，而中心轴731两端则通过转轴732与安装框72的两端活动连接，当电路板插入两个对称的滚轮73中间时，电路板的两侧将限位在限位槽733内侧，同时随着电路板的移动，滚轮73也可以发生旋转滚动，辅助电路板快速插入和抽出，而设置的橡胶圈734具有良好的缓冲防护效果，当电路板插入限位槽733内侧后，电路板的两端表面将与橡胶圈734接触，尽量避免电路板表面发生磨损。The roller 73 is rotatably connected inside the installation frame 72, and the fixed plate 71 is threadedly connected with the forward and reverse screws 62 through the movable nut 712. When the forward and reverse screws 62 drive the clamping assembly 7 to move in opposite or reverse directions, the fixed plate 71 can drive the roller 73 to move synchronously through the installation frame 72, so that the roller 73 can be clamped at both sides of the circuit board. The roller 73 is sleeved on the outside of the central shaft 731, and the two ends of the central shaft 731 are movably connected with the two ends of the installation frame 72 through the rotating shaft 732. When the circuit board is inserted between the two symmetrical rollers 73, the two sides of the circuit board will be limited in the inner side of the limiting groove 733. At the same time, as the circuit board moves, the roller 73 can also rotate and roll to assist the circuit board to be quickly inserted and withdrawn. The rubber ring 734 has a good buffering and protective effect. When the circuit board is inserted into the inner side of the limiting groove 733, the two end surfaces of the circuit board will contact the rubber ring 734 to avoid wear on the circuit board surface as much as possible.
进一步地，探针5的上端安装有挡板51(挡板51的直径大于固定套筒4底部的通孔直径)，挡板51上端安装有缓冲弹簧52，挡板51与缓冲弹簧52位于固定套筒4内部。Furthermore, a baffle 51 is installed at the upper end of the probe 5 (the diameter of the baffle 51 is larger than the diameter of the through hole at the bottom of the fixed sleeve 4 ), and a buffer spring 52 is installed at the upper end of the baffle 51 . The baffle 51 and the buffer spring 52 are located inside the fixed sleeve 4 .
当探针5下移接触电路板时，探针5将通过挡板51挤压固定套筒4内部的缓冲弹簧52进行缓冲，避免探针5下压时冲击力过大造成电路板表面受损，而由于挡板51在探针5的上方限位，使得探针5不会自行与固定套筒4产生分离。When the probe 5 moves down and contacts the circuit board, the probe 5 will use the baffle 51 to squeeze the buffer spring 52 inside the fixed sleeve 4 for buffering, thereby preventing the circuit board surface from being damaged due to excessive impact force when the probe 5 is pressed down. Since the baffle 51 is limited above the probe 5, the probe 5 will not separate from the fixed sleeve 4 by itself.
进一步地，调节组件6包括固定架61以及固定架61中间安装的正反螺杆62，正反螺杆62的一端安装有驱动轴63，驱动轴63的另一端连接有驱动电机64。Furthermore, the adjustment assembly 6 includes a fixing frame 61 and a forward and reverse screw 62 installed in the middle of the fixing frame 61 , a driving shaft 63 is installed at one end of the forward and reverse screw 62 , and a driving motor 64 is connected to the other end of the driving shaft 63 .
驱动电机64可以通过驱动轴63带动正反螺杆62正反转调节，使正反螺杆62可以带动夹持组件7呈对向或反向移动调节。The driving motor 64 can drive the forward and reverse screws 62 to adjust forward and reverse through the driving shaft 63, so that the forward and reverse screws 62 can drive the clamping assembly 7 to move in opposite or reverse directions.
进一步地，固定架61的底面中间开设有导向槽611，固定架61远离驱动电机64的一端安装有轴承座612。Furthermore, a guide groove 611 is provided in the middle of the bottom surface of the fixing frame 61 , and a bearing seat 612 is installed at one end of the fixing frame 61 away from the driving motor 64 .
正反螺杆62的一端与驱动轴63连接，另一端则与轴承座612连接固定，并且设置的导向槽611可以在夹持组件7的下方进行限位，使夹持组件7保持平移，不会跟随正反螺杆62发生转动。One end of the forward and reverse screw 62 is connected to the driving shaft 63, and the other end is fixedly connected to the bearing seat 612, and the guide groove 611 provided can limit the position below the clamping assembly 7, so that the clamping assembly 7 can maintain translation and will not rotate with the forward and reverse screw 62.
本实用新型的使用过程如下：使用时，根据电路板的宽度提前调节好两个滚轮73之间的间距，调节时，驱动电机64可以通过驱动轴63带动正反螺杆62正反转调节，固定板71通过活动螺母712与正反螺杆62螺纹连接，使得活动螺母712可以带动固定板71同步移动，而当固定板71移动时，可以通过安装框72带动滚轮73移动，当两个滚轮73之间的间距调节完成后，可以将电路板插入两个对称的滚轮73中间，此时电路板的两侧将限位在限位槽733内侧，随着电路板的移动，滚轮73也可以发生旋转滚动，辅助电路板快速插入和抽出，当电路板的两侧被夹持限位后，电路板将位于移动板2的下方，最后人员可以启动电动推杆3带动移动板2下移，而移动板2将同步带动固定套筒4和探针5向下移动，使探针5与电路板相接触，由于探针5设置为多个，从而可以对多个接点进行测试。The use process of the utility model is as follows: when in use, the spacing between the two rollers 73 is adjusted in advance according to the width of the circuit board. When adjusting, the driving motor 64 can drive the forward and reverse screws 62 to adjust forward and reverse through the driving shaft 63. The fixed plate 71 is threadedly connected with the forward and reverse screws 62 through the movable nut 712, so that the movable nut 712 can drive the fixed plate 71 to move synchronously, and when the fixed plate 71 moves, the roller 73 can be driven to move through the mounting frame 72. When the spacing between the two rollers 73 is adjusted, the circuit board can be inserted into the middle of the two symmetrical rollers 73. At this time, the two sides of the circuit board will be limited on the inner side of the limiting groove 733. As the circuit board moves, the roller 73 can also rotate and roll to assist the circuit board to be quickly inserted and extracted. When the two sides of the circuit board are clamped and limited, the circuit board will be located below the movable plate 2. Finally, the personnel can start the electric push rod 3 to drive the movable plate 2 to move downward, and the movable plate 2 will synchronously drive the fixed sleeve 4 and the probe 5 to move downward, so that the probe 5 contacts the circuit board. Since the probe 5 is set to multiple, multiple contacts can be tested.
以上所述，仅是本实用新型的较佳实施例，任何熟悉本领域的技术人员均可能利用上述阐述的技术方案对本实用新型加以修改或将其修改为等同的技术方案。因此，依据本实用新型的技术方案所进行的任何简单修改或等同置换，尽属于本实用新型要求保护的范围。The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution.
