[0036] In this way, by setting up a loading device, a tray transfer mechanism, a grabbing detection device and a receiving device, the one-stop process of testing, inspection and taping can be completed. The entire process does not require turnover, the operation is simple, and the test efficiency is improved. At the same time, the test device can be moved to separate the transfer and test stations of the WIFI module, so that the test device can test different modules, which is flexible and fast, and improves production efficiency. In addition, the use of CCD scanning can achieve one machine and one code, ensuring the uniqueness of the product, accurate positioning, and high test stability.

[0037] It is understandable that in the process of producing WIFI modules, the WIFI modules need to be placed in a blister tray, and then manually placed one by one in a test box to test the shielding performance and signal transmission performance of the WIFI modules. However, the existing loading process of the WIFI modules is relatively cumbersome, which is not conducive to automated production, and the existing loading method uses manual loading, which makes the loading efficiency low, thereby reducing the production efficiency of the WIFI modules.

[0050] In this way, by setting up the guide frame, the fixing frame, the supporting assembly and the alignment assembly, the manual operation can be replaced to complete the placement and taking of the WIFI module, simplify the loading process, facilitate the loading of the WIFI module, improve the production efficiency of the WIFI module, and speed up the automated production.

[0051] It can be understood that, at present, in the existing WIFI module production process, the WIFI module needs to be tested for wireless transmission and signal shielding. However, in the existing production process, the WIFI module after loading needs to be transferred to the testing station, and the WIFI module after the test needs to be transferred to the unloading device. During the transmission process, how to ensure that the WIFI module can smoothly reach the testing station during the transmission process, how to ensure that the grasping mechanism can accurately grasp each WIFI module, and how to improve the test reliability of the WIFI module are issues that technical personnel in this field need to consider.

[0066] It is understandable that, at present, in the production and testing process of WIFI modules, since there are multiple WIFI modules that need to be tested at one time, and each WIFI module needs to correspond to a different code, it is necessary to scan the WIFI module before testing to ensure that the WIFI module in each empty space matches the corresponding MAC address. However, there is no station for scanning code detection in the existing testing station, that is, there is no scanning code station in the gripping device, so that additional manual scanning and verification are required, resulting in low efficiency of WIFI module testing and reduced accuracy of WIFI modules. If the wrong MAC address is matched with the WIFI module, it is possible to burn the wrong program into the WIFI module, resulting in a higher defective rate of the produced WIFI modules.

[0067] In one embodiment, please refer to Figure 5 and Figure 6A grasping detection device includes: a detection table 800, a moving component 900, a suction component 1000, a code scanning component 1100 and a detection component 1200.

[0072] It should be noted that the transverse driving member includes a transverse driver, a first screw rod and a first mounting plate, the transverse driver is arranged on the fixing frame, one end of the first screw rod is arranged on the transverse driver, and the first mounting plate is arranged on the end of the first screw rod away from the transverse driver.

In this way, by setting two vacuum suction nozzles, the stability of sucking the WIFI module can be improved, and the suction effect can be improved.

[0075] At present, the existing test device cannot be moved, which makes the whole device relatively large and inconvenient to move, which reduces the practicality of the test device and reduces the production efficiency.

Specifically, there are multiple moving pulleys, and each of the moving pulleys is arranged on the shielding box. In this way, by providing the moving pulley 1230, the movement and movement of the whole device can be easily realized, which improves the practicality of the test device and improves the production efficiency.

[0076] In this way, through the detection table, the suction component, the code scanning component and the detection component, one-to-one code scanning and alignment can be achieved to ensure one machine and one code, thereby ensuring the uniqueness of the WIFI module, improving the testing efficiency of the WIFI module, and improving the accuracy of the WIFI module testing, avoiding the situation where different product addresses are matched with the WIFI module, avoiding burning the wrong program into the WIFI module, and reducing the defective rate of the WIFI module.

[0077] It can be understood that in the process of producing WIFI modules, successful WIFI modules need to be placed in a tray. However, when the tray is full of WIFI modules, the trays need to be stacked. The existing process of stacking trays is to clamp the trays with a robot and then place them on other stacked trays. This method requires the addition of a robot and a larger range of robot transfer belts, which makes the structure of the entire material receiving device complicated and easily causes the trays to be stacked unevenly, making it inconvenient for operators to take out the trays, reducing the efficiency of material transfer.

[0078] In one embodiment, please refer to Figure 8 A material collecting device includes: a collecting and stacking frame 1300, a fixing assembly 1400 and a pushing assembly 1500, wherein the collecting and stacking frame, the fixing assembly and the pushing assembly are respectively arranged on the guide rail frame. The collecting and stacking frame 1300 is used to stack trays full of WIFI modules; the fixing assembly 1400 is used to fix the stacked trays; and the pushing assembly 1500 is used to push the trays so that the trays are stacked on each other.

[0079] See also Figure 8 The collecting and stacking frame 1300 includes a plurality of fixed edges 1310, each of which is disposed on the guide rail frame, and each of which together forms a tray stacking area 1320. It should be noted that the fixed edges 1310 are used to fix trays; and the tray stacking area 1320 is used to place stacked trays.

[0080] See also Figure 8 and 9The fixing assembly 1400 includes a first rebound fixing member 1410 and a second rebound fixing member 1420, the first rebound fixing member and the second rebound fixing member are respectively arranged on the guide rail frame, the first rebound fixing member 1410 includes a first connecting seat 1411, a first rotating block 1412 and a first spring (not shown in the figure), the first connecting seat is arranged on the guide rail frame, the first rotating block is rotatably arranged on the first connecting seat, one end of the first spring is arranged on the first connecting seat, and the other end of the first spring is arranged on the first rotating block; the second rebound fixing member 1420 includes a second connecting seat 1421, a second rotating block 1422 and a second spring (not shown in the figure), the second connecting seat is arranged on the guide rail frame, the second rotating block is rotatably arranged on the second connecting seat, one end of the second spring is arranged on the second connecting seat, and the other end of the second spring is arranged on the second rotating block. It should be noted that the first resilient fixing member 1410 is used as a resilient protrusion for fixing the tray above the guide rail frame, and the second resilient fixing member 1420 also has the same structure as the first resilient fixing member 1410. The first connecting seat is used to fix the first rotating block and the first spring; the first rotating block is used to fix the tray; the first spring is used to realize the rebound of the rotating block; the second connecting seat is used to fix the second rotating block and the second spring; the second rotating block is used to fix the tray; the second spring is used to realize the rebound of the rotating block. Further, the direction in which the first spring and the second spring pull the rotating block is opposite to the direction in which the tray is stacked upward, that is, it can be understood that the spring pulls the rotating block downward, so that the first rotating block and the second rotating block have a downward pulling force respectively. In this embodiment, a rounded corner portion is provided on the first rotating block. A rounded corner portion is provided on the second rotating block. In this way, it is convenient for the rotating block to rotate.

[0081] During operation: the material tray transfer mechanism transfers the tray to the bottom of the pushing component. At this time, the pushing component pushes the tray to move upward, and then the tray continues to rise, and the upper surface of the tray abuts against the lower surfaces of the first rotating block and the second rotating block. When the tray continues to rise, the first rotating block and the second rotating block are pushed open by the upward holding force, and then the tray continues to move upward until the tray completely exceeds the rotation height of the first rotating block and the second rotating block. Finally, the first rotating block returns to its original position under the downward pulling force of the first spring. Similarly, the second rotating block also returns to its original position. Then the pushing component returns, and the stacked trays drop to the upper surface of the rotating block and are supported by the two rotating blocks so that they will not fall down, thereby realizing the collection operation of the trays.

[0082] See also Figure 8The pushing assembly 1500 includes two pushing driving parts 1510, which are respectively arranged on the guide rail frame, and the two pushing driving parts jointly push the tray to rise.

[0083] It should be noted that the collecting and stacking frame includes four fixed edge plates, which are respectively arranged on the guide rail frame, and the four fixed edge plates together form a tray stacking area. In this way, by arranging four fixed edge plates, the four end corners of the tray can be fixed, thereby improving the fixing effect on the tray.

[0084] It should be noted that the four fixed edge plates have corners respectively, and the opening direction of the corners is set toward the tray stacking area. In this way, by setting the corners, the end corners of the tray can be embedded in the corners, thereby improving the limiting effect on the tray and further improving the fixing effect on the tray.

[0085] See also Figure 8 The receiving device further includes a sensing component 1600, and the sensing component 1600 includes a mounting bracket 1610 and an infrared sensor 1620. The mounting bracket is disposed on the fixed edge plate, and the infrared sensor is disposed on the mounting bracket. In this embodiment, two sensing components are provided, and the two sensing components are respectively disposed on the two fixed edge plates. It should be noted that the mounting bracket 1610 is used to fix the infrared sensor, and the infrared sensor 1620 is used to sense the tray transferred by the tray transfer mechanism.

[0086] It should be noted that, in one of the pushing driving parts, the pushing driving part includes a driving bracket, a driver and a driving plate, the driving bracket is arranged on the first guide rail or the second guide rail, the driver is arranged on the driving bracket, and the driving plate is arranged on the driver. In this embodiment, the driver is a motor or a cylinder. In this way, by arranging the driving bracket, the driver and the driving plate, the pushing effect on the tray can be improved, and the stability of the pushing driving part can be improved.

[0087] In this way, by setting up a guide frame, a collection and stacking frame, a fixing assembly and a pushing assembly, the material collecting device has a simple structure and is easy to operate. It can also ensure that the material trays are stacked neatly and completely, avoiding the situation where it is inconvenient for operators to take out the material trays, thereby improving the material transfer efficiency and the material collecting efficiency.

[0088] The advantages and beneficial effects of the present invention compared to the prior art are as follows:

[0089] The present invention is a module testing device. By arranging a feeding device, a material tray transfer mechanism, a grasping detection device and a material receiving device, the one-stop process of testing, inspection and taping can be completed. The whole process does not require turnover, the operation is simple, and the testing efficiency is improved. At the same time, the testing device can be moved to separate the transfer and testing stations of the WIFI module, so that the testing device can test different modules, which is flexible and fast, and the production efficiency is improved. Moreover, the use of CCD scanning can realize one machine and one code, thereby ensuring the uniqueness of the product, accurate positioning and high testing stability.
