产品输送机构，如图1所示，包括进料机构1、次品传送机构2和良品传送机构5；进料机构1和次品传送机构2的传送方向为同向，且沿传送方向顺序设置；良品传送机构5与次品传送机构2并列平行设置，且传送方向可以同向，也可以不同向。The product conveying mechanism, as shown in Figure 1, includes a feeding mechanism 1, a defective product conveying mechanism 2, and a good product conveying mechanism 5; the conveying direction of the feeding mechanism 1 and the defective product conveying mechanism 2 is in the same direction, and they are arranged sequentially along the conveying direction ; Good product conveying mechanism 5 and defective product conveying mechanism 2 are arranged in parallel, and the conveying direction can be in the same direction or in different directions.

进料机构1上预设有第一位置，可选的位于第二端，在每次上料操作时上下料机构4在第一位置吸取待检测的产品。为提高效率，保证在待检测的产品被传送至第一位置的同时，上下料机构4刚好能够到达第一位置以吸取待检测的产品，本实施例在进料机构1上还设有光纤检测单元(图中未示出)，用于检测是否有待检测的产品流入，在检测到有待检测的产品流入时通知上下料机构4执行新一轮的上下料操作。光纤检测单元在进料机构1上的装配位置，可根据上下料机构4由初始位置到达第一位置的时间来定，这样可以保证上料操作的连续性，大大提高工作效率。The feeding mechanism 1 is preset with a first position, optionally located at the second end, and the loading and unloading mechanism 4 absorbs the product to be detected at the first position during each feeding operation. In order to improve efficiency and ensure that when the product to be detected is delivered to the first position, the loading and unloading mechanism 4 can just reach the first position to absorb the product to be detected. In this embodiment, the feeding mechanism 1 is also equipped with an optical fiber detection A unit (not shown in the figure) is used to detect whether there is an inflow of the product to be detected, and notify the loading and unloading mechanism 4 to perform a new round of loading and unloading operations when the inflow of the product to be detected is detected. The assembly position of the optical fiber detection unit on the feeding mechanism 1 can be determined according to the time when the loading and unloading mechanism 4 reaches the first position from the initial position, which can ensure the continuity of the feeding operation and greatly improve work efficiency.
请参阅图2，测试机构3位于预设的检测工位的附近位置，包括XY向调节机构和固定于XY向调节机构上的测试单元。XY向调节机构包括：第二驱动机构31、X向传动机构32、第三驱动机构33以及滑动设于X向传动机构32上的Y向传动机构34；测试单元滑动设于Y向传动机构34上，第二驱动机构31与X向传动机构34连接，第三驱动机构33与Y向传动机构34连接。Please refer to FIG. 2 , the testing mechanism 3 is located near the preset testing station, and includes an XY-direction adjustment mechanism and a test unit fixed on the XY-direction adjustment mechanism. The XY direction adjustment mechanism includes: the second drive mechanism 31, the X direction transmission mechanism 32, the third drive mechanism 33 and the Y direction transmission mechanism 34 slidingly arranged on the X direction transmission mechanism 32; the test unit is slidably arranged on the Y direction transmission mechanism 34 Above, the second drive mechanism 31 is connected to the X-direction transmission mechanism 34 , and the third drive mechanism 33 is connected to the Y-direction transmission mechanism 34 .
第二驱动机构31和第三驱动机构33可以为伺服电机，X向传动机构32和Y向传动机构34可以为齿轮齿条传动机构。在X向传动机构32和Y向传动机构34的导向作用下，测试单元可以沿呈水平的X向和Y向上运动，使其探测范围完全覆盖检测工位上的待检测的产品。The second driving mechanism 31 and the third driving mechanism 33 may be servo motors, and the X-direction transmission mechanism 32 and the Y-direction transmission mechanism 34 may be rack-and-pinion transmission mechanisms. Under the guidance of the X-direction transmission mechanism 32 and the Y-direction transmission mechanism 34, the test unit can move horizontally in the X direction and Y direction, so that its detection range completely covers the product to be tested on the detection station.
由于待检测的产品类型包括有多种，每种产品的型号不同，因而为了实现兼容性，本实施例可根据待检测的产品型号来控制测试单元调整至产品上方的合适位置，以保证检测结果的准确性。Since there are many types of products to be tested, and the models of each product are different, in order to achieve compatibility, this embodiment can control the test unit to be adjusted to a suitable position above the product according to the model of the product to be tested, so as to ensure the test results accuracy.
测试单元包括CCD相机35和激光检测器36，集合了两种检测器件的优点，扩展检测项目的种类。通过CCD相机35，可检测项目包括：各种元件(如射频头、麦拉、耳机胶套)是否漏装、松脱、破损等；通过激光检测器36，可检测项目包括：各种元件是否安装到位(例如：摄像头是否装配到位，FPC是否起翘、Home键是否粘贴到位、侧键FPC与A壳的定位柱是否高度一致)。The test unit includes a CCD camera 35 and a laser detector 36, which combines the advantages of the two detection devices and expands the types of detection items. Through the CCD camera 35, the detectable items include: whether various components (such as radio frequency heads, mylars, earphone rubber sleeves) are missing, loose, damaged, etc.; through the laser detector 36, the detectable items include: whether various components are The installation is in place (for example: whether the camera is assembled in place, whether the FPC is tilted, whether the Home button is pasted in place, whether the side button FPC is at the same height as the positioning column of the A shell).
另外，检测工位上固定设有定位角37和定位气缸38，定位气缸38的活塞杆端部固定有一与定位角37相对设置的推块。当第一真空吸盘42将其吸取的待检测的产品放入检测工位时，定位气缸38通过推块将待检测的产品推动至定位角37内，实现产品定位功能，有助于后续的精确检测。In addition, a positioning angle 37 and a positioning cylinder 38 are fixed on the detection station, and a push block opposite to the positioning angle 37 is fixed at the end of the piston rod of the positioning cylinder 38 . When the first vacuum chuck 42 puts the product to be detected into the detection station, the positioning cylinder 38 pushes the product to be detected into the positioning angle 37 through the push block, so as to realize the product positioning function, which is helpful for subsequent accurate detection.
上下料机构4，用于自动连续性地执行上下料操作，且同时进行上料操作和下料操作以提高工作效率。上料操作为：由进料机构1的第一位置吸取待检测的产品，将该产品送至预设的检测工位；下料操作为：由检测工位吸取已完成检测的产品，并根据检测结果将该产品送至次品传送机构2或者良品传送机构5上。The loading and unloading mechanism 4 is used to automatically and continuously perform loading and unloading operations, and simultaneously perform loading and unloading operations to improve work efficiency. The loading operation is: the first position of the feeding mechanism 1 absorbs the product to be inspected, and sends the product to the preset inspection station; the unloading operation is: the inspection station absorbs the product that has been inspected, and The detection result sends the product to the defective product conveying mechanism 2 or the good product conveying mechanism 5 .
如图3所示，上下料机构4包括运动模组，运动模组上滑动设有旋转机构41，旋转机构41的旋转轴连接有两个高度一致的真空吸盘(为方便描述，下文称为第一真空吸盘42和第二真空吸盘43)，旋转轴垂直于进料机构1的传送面。旋转机构41的运动轨迹中包括进料机构1的第一位置、次品传送机构2的上方位置和良品传送机构5的上方位置。As shown in Figure 3, loading and unloading mechanism 4 comprises motion module, is provided with rotation mechanism 41 slidingly on the movement module, and the rotation shaft of rotation mechanism 41 is connected with two vacuum chucks of consistent height (for convenience of description, hereinafter referred to as the first A vacuum chuck 42 and a second vacuum chuck 43), the rotation axis is perpendicular to the conveying surface of the feeding mechanism 1. The movement track of the rotating mechanism 41 includes the first position of the feeding mechanism 1 , the upper position of the defective product conveying mechanism 2 and the upper position of the good product conveying mechanism 5 .
在运动模组的带动下，第一真空吸盘42可由初始位置运动至进料机构1的第一位置的正上方，真空吸取第一位置上待检测的产品；与此同时，第二真空吸盘43由初始位置运动至预设的检测工位的正上方，真空吸取检测工位上已完成检测的产品；Driven by the motion module, the first vacuum chuck 42 can move from the initial position to directly above the first position of the feeding mechanism 1, and vacuum suck the product to be detected at the first position; at the same time, the second vacuum chuck 43 Move from the initial position to directly above the preset testing station, and vacuum the products that have been tested on the testing station;
在旋转机构41的作用下，第一真空吸盘42与第二真空吸盘43进行旋转，交换相互位置后，第一真空吸盘42断开真空，将其吸取的待检测的产品放入检测工位；Under the effect of the rotating mechanism 41, the first vacuum chuck 42 and the second vacuum chuck 43 rotate, after exchanging mutual positions, the first vacuum chuck 42 disconnects the vacuum, and puts the product to be detected that it sucks into the detection station;
然后，根据检测结果，在运动模组的带动下，第二真空吸盘43运动至次品传送机构2或者良品传送机构5的上方，放下已完成检测的产品，之后第一真空吸盘42与第二真空吸盘43返回至初始位置，等待下一轮的上下料操作。Then, according to the detection result, under the drive of the motion module, the second vacuum chuck 43 moves to the top of the defective product conveying mechanism 2 or the good product conveying mechanism 5, and puts down the product that has been tested, and then the first vacuum chuck 42 and the second The vacuum chuck 43 returns to the initial position, waiting for the next round of loading and unloading operations.
本实例中，检测工位设于进料机构1的第一位置附近，且检测工位与第一位置的直线距离和第一真空吸盘42与第二真空吸盘43的直线距离大致相同。这样，当第一真空吸盘42运动至第一位置的上方后，第二真空吸盘43能够刚好位于检测工位的上方，便于第一真空吸盘42与第二真空吸盘43同时吸取对应位置上的产品。In this example, the detection station is located near the first position of the feeding mechanism 1 , and the linear distance between the detection station and the first position and the linear distance between the first vacuum chuck 42 and the second vacuum chuck 43 are approximately the same. In this way, when the first vacuum chuck 42 moves to the top of the first position, the second vacuum chuck 43 can just be located above the detection station, so that the first vacuum chuck 42 and the second vacuum chuck 43 can simultaneously suck the products on the corresponding positions .
具体地，上下料机构4设于次品传送机构2的远离良品传送机构5的一侧，其运动模组包括第一驱动机构44、第一传动机构45以及滑动设于第一传动机构45上的载台46，第一驱动机构44驱动载台46在第一方向上做往返直线运动；载台46上固定装载有笔形气缸47，笔形气缸47的驱动端固定连接上述旋转气缸，在笔形气缸47的驱动作用下旋转气缸可在第二方向做往返直线运动。第一方向、第二方向以及进料机构1的传送方向均为水平方向，且第一方向与进料机构1的传送方向垂直，第二方向与进料机构1的传送方向平行。Specifically, the loading and unloading mechanism 4 is arranged on the side away from the good product conveying mechanism 5 of the defective product conveying mechanism 2, and its motion module includes a first drive mechanism 44, a first transmission mechanism 45, and a first transmission mechanism 45 slidingly arranged on the first transmission mechanism 45. The carrying platform 46, the first driving mechanism 44 drives the carrying platform 46 to do the reciprocating linear motion on the first direction; the carrying platform 46 is fixedly equipped with a pen-shaped cylinder 47, and the driving end of the pen-shaped cylinder 47 is fixedly connected to the above-mentioned rotary cylinder. Under the driving action of 47, the rotary cylinder can do linear motion back and forth in the second direction. The first direction, the second direction and the conveying direction of the feeding mechanism 1 are all horizontal directions, and the first direction is perpendicular to the conveying direction of the feeding mechanism 1 , and the second direction is parallel to the conveying direction of the feeding mechanism 1 .
其中，第一驱动机构44可以为伺服电机，第一传动机构45可以为齿轮齿条传动机构，旋转机构41可以为旋转气缸，第一真空吸盘42与第二真空吸盘43可分别通过一滑台气缸48连接至旋转气缸的旋转轴的轴头，以实现两个真空吸盘的高度可调。Wherein, the first driving mechanism 44 can be a servo motor, the first transmission mechanism 45 can be a rack and pinion transmission mechanism, the rotating mechanism 41 can be a rotary cylinder, and the first vacuum chuck 42 and the second vacuum chuck 43 can pass through a slide table respectively. The cylinder 48 is connected to the shaft head of the rotary shaft of the rotary cylinder to realize the height adjustment of the two vacuum suction cups.
上下料过程具体为：The loading and unloading process is specifically:
首先，旋转气缸沿第一方向由初始位置运动至次品传送机构2的上方，再沿第二方向运动至进料机构1的第一位置的上方，此时第一真空吸盘42与第二真空吸盘43分别位于第一位置的正上方和检测工位的正上方，之后第一真空吸盘42下降吸取待检测的产品、第二真空吸盘43下降吸取完成检测的产品；First, the rotary cylinder moves from the initial position to the top of the defective product conveying mechanism 2 along the first direction, and then moves to the top of the first position of the feeding mechanism 1 along the second direction. At this time, the first vacuum chuck 42 and the second vacuum The suction cups 43 are respectively located directly above the first position and directly above the detection station, and then the first vacuum suction cup 42 descends to absorb the product to be detected, and the second vacuum suction cup 43 descends to absorb the tested product;
然后，第一真空吸盘42与第二真空吸盘43旋转以交换位置，第一真空吸盘42移至检测工位的正上方后，将待检测的产品放置于检测工位；Then, the first vacuum chuck 42 and the second vacuum chuck 43 rotate to exchange positions, and after the first vacuum chuck 42 moves to the directly above the detection station, the product to be detected is placed on the detection station;
之后，第一真空吸盘42与第二真空吸盘43上升，沿第二方向返回至次品传送机构2的上方，第二真空吸盘43将其吸取的检测为不合格的产品放置于次品传送机构2上，或者继续沿第一方向运动至良品传送机构5的上方，将完成检测的合格产品放置于良品传送机构5上；Afterwards, the first vacuum chuck 42 and the second vacuum chuck 43 rise, return to the top of the defective product conveying mechanism 2 along the second direction, and the second vacuum sucker 43 places the unqualified products sucked by it on the defective product conveying mechanism 2, or continue to move along the first direction to the top of the good product conveying mechanism 5, and place the qualified products that have been tested on the good product conveying mechanism 5;
最后，沿第一方向，第一真空吸盘42与第二真空吸盘43返回至初始位置，等待下一轮的上下料操作。Finally, along the first direction, the first vacuum chuck 42 and the second vacuum chuck 43 return to their initial positions, waiting for the next round of loading and unloading operations.
在实际应用中，次品传送机构2和良品传送机构5的位置可进行替换，且在替换后良品传送机构5需同时调整为与进料机构1相同的传送方向，次品传送机构2的传送方向可与进料机构1同向或者不同向。此时，上下料机构4的上下料操作过程中，仅仅是针对完成检测的产品的运送行程有些改变，其他部分原理与上述相同，不再赘述。In practical applications, the positions of the defective product conveying mechanism 2 and the good product conveying mechanism 5 can be replaced, and after the replacement, the good product conveying mechanism 5 needs to be adjusted to the same conveying direction as the feeding mechanism 1 at the same time, and the conveying direction of the defective product conveying mechanism 2 The direction can be the same as that of the feeding mechanism 1 or different. At this time, during the loading and unloading operation of the loading and unloading mechanism 4 , only the delivery schedule of the tested products has been changed, and the principles of other parts are the same as above, and will not be repeated here.
综上，本实施例的内观自动检测装置可同时且自动完成产品的上料和下料，大大提高了工作效率，节省了成本；且适用于各种不同规格的产品的内观检测，检测内容也更加完善，对产品质量进行了有效地把控。To sum up, the automatic internal inspection device of this embodiment can simultaneously and automatically complete the loading and unloading of products, which greatly improves work efficiency and saves costs; and is suitable for internal inspection of products of various specifications, inspection The content is also more complete, and the product quality is effectively controlled.
