[0059] The present disclosure provides a carrier board testing system, through which the carrier board can be tested, for example, to detect whether the carrier board parameters meet the requirements. In a specific embodiment of the present disclosure, the carrier board can be, for example, a PCB board, an IC board or other plate material, and the carrier board testing system can detect the conductivity between the various circuits of the PCB board and the IC board, thereby avoiding the outflow of defective products. Of course, the carrier board of the present disclosure can also be other forms of plate materials, and different carrier boards may have different test conditions and test parameters. Those skilled in the art can select a suitable carrier board testing system according to actual needs.

[0060] The carrier testing system disclosed in the present invention can realize systematic detection of the carrier through a loading unit, a testing unit, and a unloading unit. Specifically, the loading unit is configured to load the carrier. The testing unit is configured to test the carrier, and the testing unit includes a positioning mechanism and a moving mechanism; the moving mechanism is provided with a bearing surface for bearing the carrier, and the positioning mechanism includes a whole board assembly, and the whole board assembly is configured to rise to a position at a first predetermined height from the bearing surface to straighten the carrier located on the bearing surface, and is configured to rise to a position at a second predetermined height from the bearing surface before the carrier is transferred from the loading unit to the moving mechanism, or before the carrier is transferred from the moving mechanism to the unloading unit. The unloading unit is configured to unload the carrier that has completed the test in the testing unit.

[0061] The carrier testing system disclosed in the present invention includes a whole-board assembly, through which the carrier located on the mobile mechanism can be whole-boarded, thereby improving the positioning accuracy of the carrier; in addition, before the carrier is transferred to the mobile mechanism or before the carrier on the mobile mechanism is transferred out, the whole-board assembly is raised to a position at a second predetermined height from the bearing surface of the mobile mechanism, so that during the process of carrier transfer, the whole-board assembly can support the carrier that falls from the mobile mechanism, thereby improving the success rate of the transfer.

[0062] For ease of understanding, refer to Figures 1 to 14, the specific structure and working principle of the carrier board testing system disclosed in the present invention are explained in detail in combination with an embodiment.

[0063] In order to facilitate the description of the specific structure and movement principle of the carrier test system, a first direction and a second direction intersecting the first direction are defined. The first direction may be perpendicular to the second direction or not. For the convenience of description, the carrier test system of the present invention is described by taking the first direction being perpendicular to the second direction as an example. For example, in a three-dimensional coordinate system, the first direction can be recorded as the Y-axis direction in the horizontal plane, the second direction can be recorded as the X-axis direction in the horizontal plane, and the direction perpendicular to the X-axis direction and the Y-axis direction is recorded as the Z-axis direction, that is, the height direction. The first direction, the second direction, and the height direction are only for a clearer explanation and are not a limitation on the carrier test system.

[0064] refer to Figure 1 , Figure 2 In one embodiment of the present disclosure, a carrier board test system is provided, including a loading unit 1, a testing unit 2, and a unloading unit 3. The purpose of automatically testing a carrier board 4 is achieved through the three units with different functions of loading, testing, and unloading. In one embodiment of the present disclosure, in order to protect the carrier board test system and prevent dust or moisture from affecting the internal test environment of the carrier board test system, continue to refer to Figure 1 Each functional unit is also provided with a machine cover 5 on the outside, which can not only improve the aesthetics and operational safety of the machine, but also prevent the external environment from affecting the work of the carrier test system, which is beneficial to improving the test accuracy and extending the service life of the carrier test system.

[0065] refer to Figure 2 , the loading unit 1 in the carrier test system of the present invention loads the carrier 4. The carrier 4 that has completed the loading process will be transferred to the test unit 2 for testing. Specifically, the test unit 2 includes a positioning mechanism 21 and a detection mechanism 22 arranged along a first direction. Among them, the positioning mechanism 21 positions the transferred carrier 4, and the detection mechanism 22 detects the positioned carrier 4. The positioning accuracy of the carrier 4 can be improved by the positioning mechanism 21, which is conducive to improving the docking accuracy between the detection mechanism 22 and the carrier 4, so that the test unit 2 of the present invention can meet the growing demand for high-precision testing of the carrier 4. Continue to refer to Figure 2, the blanking unit 3 includes a conveying mechanism 31 and a buffer mechanism 32 arranged along the first direction. The conveying mechanism 31 transfers the carrier plate 4 that has completed the test in the test unit 2, and the buffer mechanism 32 buffers the carrier plate 4 after blanking. Such a layout can enable the carrier plate 4 to have a simple and clear moving path, thereby shortening the time spent by the carrier plate 4 during the transfer process, which is beneficial to improving the transfer efficiency of the carrier plate test system. During the entire test process, manual intervention is minimized to the greatest extent, which is also beneficial to improving the test accuracy of the carrier plate test system.

[0066] In an embodiment of the present disclosure, refer to Figure 4 , the loading unit 1 and the blanking unit 3 are arranged on the same side of the test unit 2. The loading unit 1 and the blanking unit 3 are configured to be arranged along the first direction and at least partially overlap with the projection of the test unit 2 in the second direction. In this embodiment, the loading unit 1 and the blanking unit 3 are integrally arranged together, and the two are arranged along the first direction and arranged along the second direction with the test unit 2. The three are arranged in a "pin" shape, with a compact structure, which can improve the space utilization rate of the carrier plate test system. In addition, the loading unit 1 and the blanking unit 3 being on the same side is also beneficial to improving the efficiency of the robotic arm or the user placing the carrier plate 4 and removing the carrier plate 4 that has completed the test during loading and blanking, thereby to a certain extent being beneficial to improving the test efficiency of the carrier plate test system.

[0067] In a specific embodiment of the present disclosure, the projection of the loading unit 1 and the positioning mechanism 21 in the second direction at least partially overlap, and the projection of the blanking unit 3 and the detection mechanism 22 in the second direction at least partially overlap. In this way, after the loading unit 1 completes the loading task, the loaded carrier plate 4 can be directly transferred in the second direction to the area corresponding to the positioning mechanism 21 in the test unit 2 for subsequent processing. When the carrier plate 4 moves to the detection mechanism 22 to complete the detection, the carrier plate 4 that has completed the test can also be quickly transferred in the second direction into the blanking unit 3. During the entire detection process of the carrier plate 4, the transfer route of the carrier plate 4 is simple and fast, which can effectively avoid problems such as slow test efficiency caused by overly complex transfer routes.

[0068] In an embodiment of the present disclosure, refer to Figure 2 、 Figure 3 , the loading unit 1 and the blanking unit 3 are respectively arranged on opposite sides of the test unit 2. The loading unit 1, the test unit 2, and the conveying mechanism 31 are configured to be arranged in sequence in the second direction, and the projections of the three in the second direction at least partially overlap. In this embodiment, the loading unit 1 is located on one side of the test unit 2, and the blanking unit 3 is arranged along the first direction on the other side of the test unit 2. Such a setting can simplify the transfer route of the carrier plate 4 and improve the transfer and test efficiency without changing the basic functions of each module.

[0069] In one embodiment of the present disclosure, the projections of the loading unit 1, the positioning mechanism 21, and the conveying mechanism 31 in the second direction at least partially overlap, and the projections in the first direction are staggered, so that the carrier 4 in the loading unit 1 can be conveyed to the positioning mechanism 21 via the shortest path in the second direction. After the carrier 4 is positioned by the positioning mechanism 21, it can be conveyed to the detection mechanism 22 via the shortest path in the first direction for testing. After the carrier 4 is conveyed to the position in the first direction after the test, it can be conveyed to the conveying mechanism 31 via the shortest path in the second direction for processing.

[0070] Reference below Figure 2 Taking the arrangement mode of the loading unit 1 and the unloading unit 3 being arranged on the opposite sides of the testing unit 2 as an example, the structure and working principle of the carrier testing system disclosed in the present invention are described in detail.

[0071] In one implementation of the present disclosure, reference Figure 5 In order to speed up the loading efficiency of the carrier test system and improve the docking efficiency between the loading unit 1 and the test unit 2, the loading unit 1 disclosed in the present invention includes a base 11, a bearing part 12, and a centering mechanism 14. The bearing part 12 is controlled by the lifting mechanism 13 to move in the height direction. The centering mechanism 14 runs through the bearing part 12, and includes a fixed baffle 141 arranged on the base 11, and a centering baffle 142 that forms a centering area 143 with the fixed baffle 141. The bearing part 12 is provided with a channel for the fixed baffle 141 and the centering baffle 142 to pass through, so that the bearing part 12 can move in the height direction relative to the fixed baffle 141 and the centering baffle 142 without interfering with the fixed baffle 141 and the centering baffle 142. In addition, the channel corresponding to the centering baffle 142 on the bearing part 12 also allows the centering baffle 142 to move, so as to avoid the centering baffle 142 interfering with the bearing part 12 when moving.

[0072] In an application scenario of the present disclosure, after the carrier 4 is placed on the bearing part 12, the centering mechanism 14 will first perform centering processing on the carrier 4. After the centering processing is completed, the carrier 4 will move with the bearing part 12 until the carrier 4 moves to a preset height and stops, which is conducive to the subsequent device to obtain the carrier 4 on the bearing part 12 and improve the transportation speed from the loading unit 1 to the testing unit 2. In order to further improve the adaptability of the loading unit 1 and the testing unit 2, the bottom of the base 11 can also be provided with rollers and supporting components, so as to move the loading unit 1 according to the actual test requirements, so that the loading unit 1 and the testing unit 2 can be more adapted, so that the loading step is more efficient.

[0073] In this embodiment, in order to further improve the feeding efficiency of the feeding unit, refer to Figure 5The fixed baffle 141 and the centering baffle 142 in the centering mechanism 14 are plate-shaped structures with a certain height, so that the centering area 143 formed by the fixed baffle 141 and the centering baffle 142 can place as many carriers 4 as possible, thereby achieving the purpose of improving the loading efficiency by loading in a whole pile. In addition, the whole pile loading method also eliminates the dust-binding roller process for a single carrier 4, further improving the loading efficiency of the loading unit 1.

[0074] In order to improve the accuracy of the centering mechanism 14, two centering baffles 142 are provided, and the two centering baffles 142 move toward or away from each other to adjust the centering area 143 surrounded by the two centering baffles 142 and the fixed baffle 141. The two centering baffles 142 can be distributed on opposite sides of the fixed baffle 141 and are perpendicular to the fixed baffle 141. In this embodiment, when the carrier 4 is placed on the bearing portion 12 and at least one side is aligned and stacked with the fixed baffle 141, the centering baffles 142 at both ends of the fixed baffle 141 move relative to each other, so that the centering baffles 142 on both sides act on the carrier 4 at the same time, so that it is in an adaptive state with the centering area 143, thereby improving the alignment degree of the loading unit 1 to the carrier 4, which is conducive to improving the accuracy of the alignment and avoiding the phenomenon of tilting and spilling of the whole stack of carriers 4 during the movement of the carriers.

[0075] In this embodiment, the "centering and pushing" process is automatically controlled by the program. According to the data of the carrier 4, the external dimensions of the current carrier 4 can be obtained. The data is input into the software to calculate the displacement of the centering baffle 142, and then the centering baffle 142 is controlled to move to complete the centering and positioning operation. Or by setting a pressure sensor on the centering baffle 142, when the pushing pressure value reaches the preset pressure threshold, it indicates that the carrier 4 on the bearing part 12 is centered in place, and the centering baffle 142 stops moving at this time to prevent the damage of the carrier 4 caused by excessive pushing pressure of the centering baffle 142. It is worth noting that if the size of the current centering area 143 is smaller than the size of the carrier 4, the centering baffle 142 will first move away from each other until the size of the centering area 143 is larger than the size of the carrier 4, and then move toward each other to center the carrier 4.

[0076] In one embodiment of the present disclosure, in order to facilitate the movement of the carrier 4 on the centering baffle 142, a plurality of smooth bars 121 arranged in a matrix are provided on the bearing portion 12, and the rotation direction of the smooth bars 121 is consistent with the movement direction of the centering baffle 142, that is, the axis direction of the rotation axis of the smooth bars 121 is perpendicular to the movement direction of the centering baffle 142. The centering baffle 142 includes a plurality of baffles arranged in the second direction, and at least one baffle is provided between two adjacent smooth bars 121, and the baffle moves along the second direction in the gap between the two adjacent smooth bars 121. At this time, the carrier 4 is supported by the smooth bars 121, and under the drive of the centering mechanism 14, the carrier 4 will move under the auxiliary guiding action of the smooth bars 121, thereby improving the stability of the movement of the carrier 4, and reducing the friction generated between the carrier 4 and the bearing portion 12 during movement, thereby achieving the purpose of protecting the carrier 4.

[0077] Since the carrier 4 has the characteristics of high precision and high cost, a layer of isolation paper for protecting the carrier 4 is placed between adjacent carriers 4 during loading, so as to protect the carrier 4 and prevent damage caused by direct contact and mutual friction between multiple carriers 4 when the whole stack of carriers 4 is aligned in the loading unit 1. In one embodiment of the present disclosure, the loading unit 1 also includes a first paper picking mechanism 15, which is used to take the isolation paper on the carrier 4 to the isolation paper station 16 after the carrying part 12 rises to a predetermined position, so that the isolation paper can be taken off the carrier without manpower to complete the loading of the carrier.

[0078] In one embodiment of the present disclosure, the loading station, the first paper picking mechanism 15, and the paper separation station 16 of the loading unit 1 are located on the same side of the test unit 2 and are sequentially distributed in the first direction, so that after the carrier 4 rises to a predetermined height under the action of the bearing portion 12, the first paper picking mechanism 15 can directly remove the separation paper on the carrier 4 and place it on the paper separation station 16 located on the other side thereof for storage. For the arrangement of the first paper picking mechanism 15 and the paper separation station 16, those skilled in the art can select and design them according to actual needs, and the present disclosure does not impose too many restrictions here.

[0079] refer to Figure 2, the test unit 2 includes a moving mechanism 23 and a first pick-and-place mechanism 25. The moving mechanism 23 is provided with a bearing surface for carrying the carrier 4. After the carrier 4 is placed on the bearing surface of the moving mechanism 23, the moving mechanism 23 clamps the carrier 4 and moves it at least in the first direction to drive the carrier 4 to move to positions corresponding to the positioning mechanism 21 and the detection mechanism 22 respectively. The first pick-and-place mechanism 25 includes a first pick-and-place beam 251, a first pick-and-place assembly 252 movably arranged on the first pick-and-place beam 251, and a second pick-and-place assembly 253. Specifically, the first pick-and-place beam 251 can extend from a position corresponding to the loading unit 1 to a position corresponding to the conveying mechanism 31 in the second direction. The first pick-and-place assembly 252 reciprocates between the loading unit 1 and the moving mechanism 23 to transfer the carrier 4 between the loading unit 1 and the moving mechanism 23. The second pick-and-place assembly 253 reciprocates between the moving mechanism 23 and the unloading unit 3 to transfer the carrier 4 between the moving mechanism 23 and the unloading unit 3. The first pick-and-place assembly 252 and the second pick-and-place assembly 253 of the present disclosure can realize the transportation of the carrier 4 by vacuum suction, magnetic adsorption, grabbing, clamping or other means well known to those skilled in the art, which will not be described in detail in the present disclosure.

[0080] refer to Figure 2 , the loading plate 4 and the mobile mechanism 23 in the loading unit 1 are located within the moving range of the first pick-and-place component 252. The loading unit 1 is located on the left side of the test unit 2 in the second direction. When the first pick-and-place component 252 moves to the left end of its stroke, it can obtain the loading plate 4 in the loading unit 1. After the first pick-and-place component 252 obtains the loading plate 4, it will move toward the right along the second direction until it moves to a position that at least partially overlaps with the projection range of the mobile mechanism 23 in the height direction. Then the first pick-and-place component 252 cooperates with the mobile mechanism 23 to complete the transfer and docking of the loading plate 4, thereby achieving the purpose of transferring the loading plate 4 from the loading unit 1 to the mobile mechanism 23.

[0081] In one embodiment of the present disclosure, the unloading unit 3 is located on the right side of the testing unit 2 in the second direction, and when the second pick-and-place assembly 253 moves to the left end of its travel, it can obtain the carrier board 4 that has completed the test in the testing unit 2. After the second pick-and-place assembly 253 obtains the carrier board 4, it will move toward the right side along the second direction until it moves to a position that at least partially overlaps with the projection range of the unloading unit 3 in the height direction, and then the second pick-and-place assembly 253 cooperates with the conveying mechanism 31 in the unloading unit 3 to complete the transfer and docking of the carrier board 4, thereby achieving the purpose of transferring the carrier board 4 from the testing unit 2 to the unloading unit 3.

[0082] The first pick-and-place assembly 252 and the second pick-and-place assembly 253 disclosed in the present invention can be movably connected to the first pick-and-place beam 251 through sprockets, transmission belts, racks or methods well known to those skilled in the art. The first pick-and-place assembly 252 and the second pick-and-place assembly 253 disclosed in the present invention can move independently or synchronously. For example, the first pick-and-place assembly 252 and the second pick-and-place assembly 253 can be connected to the same transmission belt, so that when the transmission belt rotates, it can drive the first pick-and-place assembly 252 and the second pick-and-place assembly 253 to move synchronously on the first pick-and-place beam 251, so that when the first pick-and-place assembly 252 transfers the carrier 4 in the loading unit 1 to the moving mechanism 23, the second pick-and-place assembly 253 can synchronously transfer the carrier 4 that has been tested to the conveying mechanism 31 of the unloading unit 3, thereby improving the circulation efficiency of the carrier 4.

[0083] refer to Figure 6 , Figure 8 The mobile mechanism 23 of the present disclosure includes a mobile frame 231 and at least two groups of clamping mechanisms 24 arranged on the mobile frame 231. The clamping mechanisms 24 are used to clamp the opposite sides of the carrier plate 4, so as to fix the carrier plate 4 and the mobile mechanism 23.

[0084] In the mobile mechanism 23 of the present disclosure, mobile rails 232 are provided on opposite sides of the mobile frame 231, and a clamping mechanism 24 is provided on each mobile rail 232, and the mobile rails 232 can move toward or away from the mobile frame 231. In this way, changing the distance between the two mobile rails 232 means changing the distance between the two sets of clamping mechanisms 24, so that the two sets of clamping mechanisms 24 can clamp carriers 4 of different sizes.

[0085] Specifically, refer to Figure 6 , Figure 8 Each group of clamping mechanisms 24 includes a plurality of clamping assemblies 241 spaced apart and distributed along the extending direction of the movable slide rail 232; the clamping assemblies 241 are slidably disposed on the movable slide rail 232. Fig. 9 , Fig.10The clamping assembly 241 includes a mounting base 2411, and a first clamping head 2412 disposed on the mounting base 2411; and also includes a second clamping head 2413 hinged on the mounting base 2411, and the second clamping head 2413 is controlled by a driving device such as a cylinder 2415 to clamp together or separate with the first clamping head 2412, thereby clamping the side edge of the carrier 4, thereby achieving the fixation of the carrier 4 and the clamping assembly 241. Each mounting base 2411 is configured to slide with the movable slide rail 232, and the clamping assembly 241 also includes a locking member 2414. After the mounting base 2411 moves to a predetermined position relative to the movable frame 231, the locking member 2414 is used to lock the mounting base 2411 on the movable slide rail 232, so as to ensure that the position between the clamping assembly 241 and the carrier 4 is fixed during the test process, so as to avoid unnecessary influence on the test result of the carrier 4 due to the position change of the clamping assembly 241.

[0086] In a specific embodiment of the present disclosure, the cylinder 2415 (driving device) is arranged on the mounting base 2411, the second clamping head 2413 is configured to be hinged on the mounting base 2411 through the connecting rod 2416, and the output end of the cylinder 2415 is configured to be matched with the connecting rod 2416 through the waist-shaped hole. Through the above structure, the cylinder 2415 is used as a power source, and the cylinder 2415 extends and pushes the connecting rod 2416, and the connecting rod 2416 moves around the waist-shaped hole to realize the downward movement of the second clamping head 2413, and finally cooperates with the first clamping head 2412 to complete the clamping action, thereby fixing the carrier plate 4.

[0087] The clamping assembly 241 disclosed in the present invention has a compact overall structure and can be adapted to carriers 4 of different specifications and sizes. The clamping area of ​​the clamping part of the clamping assembly 241 is small, which will not cause excessive interference to the main part of the carrier 4, and is conducive to increasing the test contact area of ​​the carrier 4. In a specific embodiment of the present invention, the first clamping head 2412 and the second clamping head 2413 are both made of plastic material, which is insulated and is conducive to increasing the friction between the carrier and the carrier, and can protect the carrier 4 while ensuring stability.

[0088] In order to improve the work efficiency of test unit 2, refer to Figure 6In one embodiment of the present disclosure, the test unit 2 is staggered with two moving mechanisms 23 in the second direction. For a clearer explanation, in the present embodiment, the two moving mechanisms 23 are respectively recorded as a first moving mechanism and a second moving mechanism. The specific structures and movement principles of the first moving mechanism and the second moving mechanism are the same, and the present disclosure will not go into details here. In a specific application scenario of the present disclosure, when the first moving mechanism drives the carrier 4 to move to the area where the detection mechanism 22 is located for detection, the second moving mechanism moves the carrier 4 that has completed the test at the detection mechanism 22 to the positioning mechanism 21, and the two operate alternately, and cooperate with the first pick-and-place component 252 and the second pick-and-place component 253 to improve the test efficiency of the carrier 4.

[0089] The mobile frame 231 is used to drive the carrier 4 to reciprocate between the position corresponding to the positioning mechanism 21 and the position corresponding to the detection mechanism 22, so that the carrier 4 positioned by the positioning mechanism 21 can be transferred to the detection mechanism 22 for testing. In one embodiment of the present disclosure, in order to enable the carrier 4 to be stably transferred to the mobile mechanism 23 and to ensure the positioning accuracy of the carrier 4 on the mobile mechanism 23, the positioning mechanism 21 includes a whole plate assembly 211, which is configured to rise to a position at a first predetermined height from the bearing surface to straighten the carrier 4 located on the bearing surface, and is configured to rise to a position at a second predetermined height from the bearing surface before the carrier 4 is transferred from the loading unit 1 to the moving mechanism 23, or before the carrier 4 is transferred from the moving mechanism 23 to the unloading unit 3. That is, after the carrier 4 is transferred to the mobile mechanism 23, the whole plate assembly 211 can rise to the first predetermined height, so that the whole plate assembly 211 can perform whole plate operation on the carrier 4 on the mobile mechanism 23, that is, adjust the position of the carrier 4 on the mobile mechanism 23 to improve the position accuracy of the carrier 4 on the mobile mechanism 23. Before the carrier 4 is transferred from the loading unit 1 to the mobile mechanism 23, the whole plate assembly 211 rises to a position at a second predetermined height from the bearing surface, so that when the carrier 4 is not aligned with the mobile mechanism 23, that is, there is a certain deviation between the carrier 4 and the bearing surface of the mobile mechanism 23, the whole plate assembly 211 can lift the carrier 4, and the carrier 4 can be repositioned through the whole plate operation of the whole plate assembly 211 later to prevent the carrier 4 from falling off the mobile mechanism 23, thereby improving the success rate of the transfer of the carrier 4. Before the carrier 4 is transferred from the moving mechanism 23 to the unloading unit 3, the whole plate assembly 211 can also rise to a position at a second predetermined height from the carrying surface, so that when the pick-and-place assembly grabs the carrier 4, the carrier 4 is prevented from being displaced and falling from the moving mechanism 23 when in contact with the pick-and-place assembly. In the embodiment of the present disclosure, the whole plate assembly 211 performs different operations at the first predetermined height and the second predetermined height, which can not only adjust the position of the carrier 4, but also cooperate with other mechanisms to realize the transfer of the carrier 4.

[0090] In a specific embodiment of the present disclosure, reference Fig.13 The whole plate assembly 211 includes a lifting seat 212, and at least two whole plate components 213 arranged on the lifting seat 212, and the at least two whole plate components 213 are constructed to move toward or away from each other on the lifting seat 212 to whole the carrier plate 4 located on the supporting surface; wherein the lifting seat 212 is constructed to rise to a position where the top end surface of the lifting seat or the top end surface of the whole plate component 213 is at a second predetermined height away from the supporting surface.

[0091] Specifically, refer to Fig.13 , when the carrier 4 is placed on the mobile mechanism 23, the position of the carrier 4 on the mobile mechanism 23 may have a large deviation, thereby affecting the subsequent test of the carrier 4. Therefore, the carrier 4 located on the mobile mechanism 23 can be pre-positioned by the whole plate 213, or it is called the whole plate operation. That is, when the whole plate assembly 211 rises to the first predetermined height, the two whole plate members 213 on the lifting seat 212 will pass through the hollow frame of the mobile mechanism 23 and correspond to the two side walls opposite to the carrier 4. When the two whole plate members 213 move toward each other, the two whole plate members 213 can push the carrier 4 to move to the predetermined position, thereby realizing the preliminary positioning of the carrier 4. In one embodiment of the present disclosure, the two whole plate members 213 are arranged at intervals in the second direction, and move toward or away from each other in the second direction to adjust the spacing between the two whole plate members 213 in the second direction to make it compatible with the specifications of the carrier 4, so that the two whole plate members 213 can perform preliminary positioning of the carrier 4 in the second direction, and reduce the displacement or deflection of the carrier 4 in the second direction. The carrier plate 4 on the moving mechanism 23 can be straightened by the straightening assembly 211, thereby improving the position accuracy of the carrier plate 4. In this embodiment, in order to improve the supporting capacity and straightening capacity of the straightening component 213, the straightening component 213 is designed in a "T" shape.

[0092] In a specific embodiment of the present disclosure, reference Figure 2 , Figure 6Before the first pick-and-place assembly 252 transfers the carrier 4 to the mobile frame 231, the mobile frame 231 moves along the second direction to the position above the whole plate assembly 211, and the lifting seat 212 rises to a position at a predetermined height from the bearing surface of the mobile mechanism 23, and the first pick-and-place mechanism 25 will transfer the carrier 4 in the loading unit 1 to the mobile mechanism 23. In a specific application scenario of the present disclosure, the predetermined height can be the position where the lifting seat 212 rises to a position where the top end surface of the lifting seat 212 or the top end surface of the whole plate 213 is at a second predetermined height from the bearing surface. During the transfer process, after the first pick-and-place mechanism 25 releases the carrier 4, before the carrier 4 is placed on the mobile mechanism 23, it will be in a free state. At this time, in order to avoid a large movement of the carrier 4, the lifting seat 212 that rises to the second predetermined height will assist, support, and other supporting functions for the carrier 4 in the free state, so that the carrier 4 can be stably placed on the mobile mechanism 23, thereby completing the transfer operation. Alternatively, when the carrier plate 4 is displaced and not aligned with the moving mechanism 23 , the lifting seat 212 will support the falling carrier plate 4 , thereby preventing the carrier plate 4 from falling from the moving mechanism 23 .

[0093] In a specific embodiment of the present disclosure, the second predetermined height is less than 0.5 mm. Since the distance between the top end face of the lifting seat 212 and the bearing surface is less than 0.5 mm, after the first pick-and-place assembly 252 releases the carrier 4, the upper end face of the lifting seat 212 can, to a certain extent, support the carrier 4 in a free state, thereby preventing the carrier 4 from falling off the moving mechanism 23 due to the offset problem before the whole board is assembled, thereby facilitating the fixing of the carrier 4 by the moving mechanism 23 and improving the success rate of the docking between the moving mechanism 23 and the first pick-and-place assembly 252. Even if the carrier 4 falls off the moving mechanism 23 due to excessive offset, it will be received on the upper end face of the lifting seat 212, and will be corrected and returned to the moving mechanism 23 in the subsequent whole board operation. Of course, the distance between the top end face of the whole board 213 and the bearing surface may be less than 0.5 mm, and the present disclosure does not impose too many restrictions on this.

[0094] In one embodiment of the present disclosure, the upper end surface of the lifting seat 212 can be made flush with the bearing surface of the moving mechanism 23, so that the upper end surface of the lifting seat 212 can provide good support for the carrier 4, thereby preventing the carrier 4 from falling from the hollow area on the moving frame 231 of the moving mechanism 23 due to offset problems.

[0095] After the test is completed, the carrier needs to be transferred from the mobile mechanism 23 to the unloading unit 3. For example, the carrier 4 on the mobile mechanism 23 can be transferred to the unloading unit 3 through the second pick-and-place assembly 253. When the second pick-and-place assembly 253 moves to the mobile mechanism 23 and contacts the carrier 4, the carrier 4 may be displaced and fall from the mobile mechanism 23. Based on this, before the carrier 4 is transferred from the mobile mechanism 23 to the unloading unit 3, the lifting seat 212 rises to a position where the top end surface of the lifting seat 212 or the top end surface of the whole plate 213 is at a second predetermined height from the bearing surface, so that the top end surface of the lifting seat 212 or the top end surface of the whole plate 213 can support the carrier 4, thereby preventing the carrier 4 from being displaced and falling from the mobile mechanism 23.

[0096] In one embodiment of the present disclosure, the carrier plate 4 that has completed positioning will be rotated to the detection mechanism 22 by the moving mechanism 23, and the detection of the carrier plate 4 will be completed at the detection mechanism 22. The present disclosure also uses a control unit to record the test results of the carrier plate 4, so as to classify and mark the carrier plate 4 currently being tested. After the detection mechanism 22 completes the pressing test of the carrier plate 4 and records the results, the moving frame 231 holding the carrier plate 4 will move along the second direction and reset to the initial position. After the reset is completed, the moving mechanism 23 will move along the first direction until it moves to the position corresponding to the whole plate assembly 211. At this time, similar to loading, the first pick-and-place mechanism 25, the moving mechanism 23, and the whole plate assembly 211 cooperate with each other, and the first pick-and-place mechanism 25 takes out the carrier plate 4 on the moving mechanism 23.

[0097] To avoid the influence of static electricity on the test, refer to Figure 7 The test unit 2 further includes a static electricity removal mechanism 26 , which is configured to blow ion wind toward the positioning mechanism 21 and / or the detection mechanism 22 to remove static electricity.

[0098] In a specific embodiment of the present disclosure, Figure 7 The static electricity removal mechanism 26 specifically includes a lower static electricity removal component 261 and an upper static electricity removal component 262. The lower static electricity removal component is arranged on the frame of the test unit 2, and the upper static electricity removal component 262 is arranged on the gantry of the test unit 2. The two components blow ion winds at different heights to the positioning mechanism 21 and / or the detection mechanism 22 to remove static electricity. Through multiple angles, the static electricity attached to the carrier 4 is minimized to the greatest extent, which is conducive to improving the accuracy of the test results.

[0099] In a specific embodiment of the present disclosure, reference Figure 7At least two lower static-eliminating components 261 are provided, and at least one lower static-eliminating component 261 blows out ion wind from the inside of the machine toward the positioning mechanism 21, so that the dust at the positioning mechanism 21 can be blown out while removing static electricity. At least one lower static-eliminating component 261 blows out ion wind from the inside of the machine toward the detection mechanism 22, so that the dust at the detection mechanism 22 can be blown out while removing static electricity, and the static electricity attached to the carrier 4 can also be reduced, which is beneficial to improve the accuracy of the test results.

[0100] In this embodiment, at least three upper static electricity removal components 262 are provided, and they are respectively located at different positions on the gantry of the test unit 2, so that static electricity removal can be performed on the working space of the test unit 2 from multiple angles and different directions. Figure 7 One of the upper static elimination components 262 is arranged at the top of the gantry, and the other two upper static elimination components 262 are arranged on the opposite sides of the gantry. Thus, ion wind can be blown to the top and opposite sides of the detection mechanism 22 through the upper static elimination components 262 at three different positions.

[0101] refer to Fig.11 The unloading unit 3 includes a cache mechanism 32, a conveying mechanism 31 and a second pick-and-place mechanism 33. The cache mechanism 32 is used to store the carrier 4. The conveying mechanism 31 and the cache mechanism 32 are arranged along the first direction. The conveying mechanism 31 is provided with at least a take-out position 37 adjacent to the cache mechanism 32, and can convey the carrier 4 to the take-out position 37 in the first direction. The second pick-and-place mechanism 33 transfers the carrier 4 located at the take-out position 37 to the cache mechanism 32 for storage. Specifically, the second pick-and-place mechanism 33 is constructed to extend along the direction from the conveying mechanism 31 to the cache mechanism 32, that is, the second pick-and-place mechanism 33 extends in the first direction to the position corresponding to the cache mechanism 32 due to the position corresponding to the conveying mechanism 31, so that the second pick-and-place mechanism 33 transfers the carrier 4. Such a layout arrangement can make the carrier 4 have a simple and clear unloading movement path, thereby shortening the time spent on the carrier 4 when being transferred in the unloading unit 3, which is conducive to improving the test efficiency.

[0102] Continue to refer Fig.11The conveying mechanism 31 includes a bracket 311 and a conveying platform 312. Considering that PCB sheets of different specifications have different external dimensions, when the conveying platform 312 moves, especially when acceleration and deceleration occur during the movement, it may cause the carrier 4 on the conveying platform 312 to be slightly displaced or rotated along its movement direction, resulting in deviation in the position of the carrier, which affects the execution of other tasks in the unloading unit 3. To this end, in one embodiment of the present disclosure, a limiting unit is provided on the conveying platform 312, and the limiting unit is constructed to limit the carrier on the conveying platform 312 at least in the first direction. In this way, when the carrier is placed on the conveying platform 312, the displacement of the carrier in the first direction can be limited by the limiting unit, so that when the carrier accelerates and decelerates in the first direction as the conveying platform 312 accelerates and decelerates in the first direction, the displacement of the carrier in the first direction can be avoided, thereby ensuring the docking accuracy of the carrier with the second pick-and-place mechanism 33, or the docking accuracy with the corresponding mechanism on other stations.

[0103] In one embodiment of the present disclosure, reference Figure 2 , the unloading unit 3 also includes a marking mechanism 35. When a carrier 4 is placed at the placement position 36 of the conveying mechanism 31, the marking mechanism 35 marks the carrier 4, and the marking mechanism 35 can be set above the placement position 36. The initial position of the conveying platform 312 is located at the placement position 36. In this way, when the carrier 4 is taken out from the test unit 2, it is directly placed on the conveying platform 312 at the placement position 36, and effective limit is performed. Then the marking mechanism marks the carrier 4. After marking, the conveying platform 312 moves toward the direction of the cache mechanism 32 to the removal position 37, and the third pick-and-place component 332 takes the carrier out of the conveying platform 312 and transfers it to the cache mechanism 32. Of course, if it is not necessary to mark the carrier 4, the conveying platform 312 directly transfers the carrier 4 from the placement position to the removal position 37, and then uses the second pick-and-place mechanism 33 to take the carrier 4 at the removal position 37 to the cache mechanism 32 for caching.

[0104] In one embodiment of the present disclosure, in order to increase the unloading efficiency of the unloading unit 3 and realize the classification processing of the carrier 4, the buffer mechanism 32 includes at least two unloading platforms 321. The unloading platforms 321 are controlled by respective lifting components 322 and are configured to move downward a preset distance after each placement of the carrier 4.

[0105] In a specific application scenario of the present disclosure, reference Fig.11 , Fig.12, the carriers 4 are divided into three categories according to the results after the test processing, so there are also three corresponding unloading platforms 321. According to the test results or types of the carriers 4, the carriers 4 that have completed the test can be placed on the unloading platform 321 corresponding to the test results. After the carrier 4 is placed on the unloading platform 321 corresponding to its test results, the detection device 323 located on one side of the unloading platform 321 will recognize that there are carriers 4 stored on the current unloading platform 321. Therefore, in order to avoid too many carriers 4 stacked too high, affecting the next operation of the second pick-and-place mechanism 33, or to avoid the unloading of the carriers 4 that are stacked too high, the detection device 323 will send a start command to the lifting component 322 after identification, so that it drives the corresponding unloading platform 321 to move downward in the height direction by a predetermined distance, so that the height of the unloading platform 321 and the carriers 4 placed thereon are always within the predetermined height range, which is not only convenient for the robot arm or the user to collect the carriers 4 that have completed the test, but also conducive to improving the safety of the equipment.

[0106] In a specific application scenario of the present disclosure, when the unloading platform 321 is located at the bottom layer, that is, the lifting component 322 moves to the lowest point, or the number of carrier plates 4 stacked on the unloading platform 321 reaches a preset number, the entire stack of carrier plates 4 stacked on the unloading platform 321 will be transported to the next processing procedure.

[0107] In one embodiment of the present disclosure, for the purpose of protecting the carrier 4 and avoiding friction or extrusion between the stacked carriers 4, reference Figure 3 , the unloading unit 3 also includes a paper separation platform 34, on which paper separations are stored. The second pick-up and placement mechanism 33 is used not only to transfer the carrier plate 4 on the conveying mechanism 31 to the cache mechanism 32, but also to pick up and place the paper separations on the paper separation platform 34 onto the carrier plate 4 of the cache mechanism 32. This allows the unloading platform 321 to have multiple carrier plates 4 stacked, and the spacers between two adjacent carrier plates 4 and the surface of the carrier plate 4 at the top to be protected by paper separations. Specifically, the structure of the paper separation platform 34 can be the same as that of the unloading platform 321, except that when each piece of paper separation is taken out from the paper separation platform 34, the paper separation platform 34 moves upward by a predetermined distance under the control of its detection device 323, so that the height of the topmost paper separation on the paper separation platform 34 is always within a predetermined height range, which facilitates the subsequent grabbing of the paper separation by the second pick-up and placement mechanism 33.

[0108] In one embodiment of the present disclosure, reference Fig.11 The conveying mechanism 31, the buffer mechanism 32, and the paper separation platform 34 are configured to be distributed in sequence along the first direction, so that the second pick-and-place mechanism 33 can move along the first direction to complete all operations such as picking up and placing the carrier plate and picking up and placing the paper separation.

[0109] The present disclosure also provides a method for transferring a carrier plate, referring to Fig.14 The carrier testing method is applicable to the above-mentioned carrier testing system. Specifically, the carrier transfer method includes the following steps:

[0110] First, the moving mechanism 23 moves unloaded to a position corresponding to the whole board assembly 211. Specifically, before the carrier board 4 is transferred from the loading unit 1 to the testing unit 2, the moving mechanism 23 in the testing unit 2 first moves to the top of the positioning mechanism 21, and at this time, the projections of the moving mechanism 23 and the positioning mechanism 21 in the height direction are at least partially overlapped.

[0111] Next, after the whole plate assembly 211 rises to the position of the second predetermined height from the bearing surface, the carrier plate 4 loaded at the loading unit 1 is transferred to the bearing surface of the moving mechanism 23. Specifically, after the moving mechanism 23 moves to the position, the whole plate assembly 211 moves to the position of the second predetermined height from the bearing surface, the first pick-and-place assembly 252 takes out the carrier plate 4 loaded at the loading unit 1, and after moving to the position corresponding to the moving mechanism 23, places the carrier plate 4 on the moving mechanism 23. At this time, if the carrier plate 4 is offset during the placement process, the carrier plate 4 falls on the whole plate assembly 211, thereby ensuring that the carrier plate 4 will not fall. In addition, the lifting seat 212 can also be raised to the position of the second predetermined height from the bearing surface, so that the lifting seat 212 can be used to support the carrier plate 4 to prevent the carrier plate 4 from falling. The second predetermined height used in this embodiment is a position less than 0.5 mm from the bearing surface.

[0112] Then, the whole board assembly 211 rises to the position of the first predetermined height to perform whole board operation on the carrier on the carrying surface. Specifically, after the carrier 4 is placed on the moving mechanism 23, the whole board assembly 211 moves from the position of the second predetermined height to the position of the first predetermined height, and performs whole board operation on the carrier 4 on the carrying surface. At this time, the carrier 4 is only placed on the moving mechanism 23, and the whole board assembly 211 in the positioning mechanism 21 will move toward each other until the position of the carrier 4 on the moving mechanism 23 is adjusted, so that the carrier 4 moves to the preset position, and the initial positioning of the carrier 4 is completed. After the positioning mechanism 21 completes the whole board operation on the carrier 4, the moving mechanism 23 will fix the carrier 4 on it to limit the displacement of the carrier 4. By keeping the position of the carrier 4 fixed, it is convenient to drive the carrier 4 to move between the various stations in the future.

[0113] Afterwards, the carrier 4 is moved by the moving mechanism 23 to the detection mechanism 22 for testing. After the test of the carrier 4 is completed, the moving mechanism 23 moves together with the tested carrier to a position corresponding to the whole board assembly 211. After the moving mechanism 23 moves to the position, the locking state of the carrier 4 is released so that the carrier 4 can be subsequently transferred to the unloading unit 3 for unloading operation.

[0114] Finally, after the whole plate assembly 211 rises to the position of the second predetermined height from the bearing surface, the carrier plate 4 on the moving mechanism 23 is transferred to the unloading unit 3. Specifically, before transferring the carrier plate 4 to the unloading unit 3, the whole plate assembly 211 rises to the position of the second predetermined height from the bearing surface, so as to cooperate with the moving mechanism 23 to stably transfer the carrier plate 4 to the unloading unit 3.

[0115] In one embodiment of the present disclosure, before the mobile mechanism 23 moves unloaded to a position corresponding to the whole board assembly 211, it also includes loading the carrier 4 at the loading unit 1. Specifically, the robot arm or the user places the whole stack of carriers 4 at the loading unit 1 to load the whole stack of carriers 4. Of course, optionally, the robot arm or the user can also place a single carrier 4 at the loading unit 1 so that the loading unit 1 can align and load the carrier 4 placed inside the loading unit 1. After the alignment and loading are completed, the carrier 4 will cooperate with the test unit 2 and be transferred from the loading unit 1 to the test unit 2 so that the test unit 2 can position and detect the carrier 4.

[0116] In a specific embodiment of the present disclosure, the loading step includes:

[0117] First, a plurality of carriers 4 are stacked on the carrier portion 12; the centering mechanism 14 moves relative to the carrier portion 12, thereby centering and aligning the plurality of carriers 4. Specifically, before placing the carrier 4 on the carrier portion 12, the centering mechanism 14 is configured to move in opposite directions so that the lengths of the two in the second direction are greater than the length of the carrier 4 to be loaded, so that the robot arm or the user can easily place the carrier 4 on the carrier portion 12. After the carrier 4 is placed on the carrier portion 12, the centering mechanism 14 moves in opposite directions so that the carrier 4 moves to a preset position along the second direction, thereby completing the centering and aligning of the carrier 4.

[0118] Then, the load-bearing part 12 rises to a preset height, or the load-bearing part 12 rises to the target height until the topmost carrier board 4 is reached. Specifically, the preset height may be the position where the load-bearing part 12 is extended in the height direction, or the height position of the carrier board 4 located at the topmost layer in the height direction, as long as it can be achieved that after the loading unit 1 completes the loading operation, the first pick-and-place component 252 in the test unit 2 can obtain the carrier board 4 located in the loading unit 1 and loaded in place. For example, the above-mentioned preset height may be the height position at which the topmost carrier board 4 reaches the height position to be taken out by the first pick-and-place component 252, and the present disclosure does not impose too many restrictions on this.

[0119] In one embodiment of the present disclosure, after the carrier 4 on the moving mechanism 23 is transferred to the unloading unit 3, the unloading unit 3 also includes classifying and caching the carrier 4 in the unloading unit 3 according to the test results. Specifically, after the test unit 2 completes the test of the carrier 4 transferred to the test unit 2, the carrier 4 that has completed the test can be transferred from the test unit 2 to the unloading unit 3, so that the unloading unit 3 can unload the carrier 4 and classify and cache it according to the test results. In this embodiment, after the test unit 2 tests the carrier 4, each tested carrier 4 will have a corresponding test result. When the carrier 4 that has completed the test is transferred to the unloading unit 3, the unloading unit 3 will classify and cache the carrier 4 based on the test results of the carrier 4, so that different processes can be performed on the carriers 4 with different test results in the future.

[0120] In one embodiment of the present disclosure, the step of blanking includes:

[0121] First, the conveying platform 312 moves to the placement position 36. The carrier 4 that has completed the inspection will be transferred to the placement position 36 of the conveying mechanism 31, so before transferring the carrier 4 that has completed the inspection, the conveying platform 312 will first move to the placement position 36 to obtain the carrier 4 transferred to the unloading unit 3.

[0122] Then, the carrier board 4 that has completed the inspection at the testing unit 2 is transferred to the conveying platform 312 , and the inspection result of the carrier board 4 is obtained.

[0123] Next, when it is necessary to perform marking operation on the carrier board 4 , the carrier board 4 located at the placement position 36 is marked.

[0124] Afterwards, the conveying platform 312 drives the carrier plate 4 to move to the removal position 37 . The carrier plate 4 that has completed the marking operation will continue to be driven by the conveying platform 312 to the removal position 37 .

[0125] Finally, the carrier plate 4 is transferred from the conveying platform 312 to the buffer mechanism 32 , and classified and buffered based on the detection result of the carrier plate 4 .

[0126] It should be noted that other steps may be interspersed between the above method steps to achieve other process functions; or some steps may be omitted to omit the corresponding process functions, and this application does not limit the steps to be closely connected. Other related method steps obtained by those skilled in the art through the embodiments of this application should also fall within the scope of protection of this application.
