[0022] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0023] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0024] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 2 As shown, an automatic sorting and unloading device for storage PCB boards includes a chassis 1 and an automatic sorting and unloading device mounted on the chassis 1. It can inspect the storage PCB boards placed in the fixture after processing and production, and automatically remove qualified products and defective products from the mold according to the inspection results, thereby realizing the automated inspection and unloading of storage PCB boards. This can effectively improve production efficiency and reduce the production cost of finished products, while also improving the accuracy of inspection, sorting and unloading.

[0026] The automatic sorting and unloading device of this embodiment includes a conveyor track 2 mounted flat on the chassis 1, and an electrical testing mechanism 3 and a unloading and collecting mechanism positioned opposite each other on both sides of the conveyor track 2. Conveyor belts are installed on the two inner sides of the conveyor track 2. The starting section of the conveyor track 2 is connected to the output end of the upstream processing equipment, allowing the stored PCB boards to be automatically transported to the conveyor track 2 for inspection and sorting after processing. The electrical testing mechanism 3 is located on one side of the conveyor track 2 and extends above it. When the stored PCB boards are transported to the position below the electrical testing mechanism 3, the electrical testing mechanism 3 can perform electrical testing on the stored PCB boards to determine their product condition. The unloading and collecting mechanism is located on the side of the conveyor track 2 opposite to the electrical testing mechanism 3. It can classify and collect defective and qualified products according to the detection results of the electrical testing mechanism 3, effectively improving production efficiency and reducing the production cost, while also improving the accuracy of inspection, sorting, and unloading.

[0027] Specifically, the electrical testing mechanism 3 of this embodiment includes a detection lifting module 31 vertically arranged on the side of the conveyor track 2 and a detection plate 32 drivenly connected to the detection lifting module 31. The detection plate 32 extends above the conveyor track 2, and its bottom is provided with multiple detection probes corresponding to the metal contacts of the storage PCB board. When the storage PCB board moves to the detection position via the conveyor track 2, the detection lifting module 31 can drive the detection plate 32 to move vertically and press it down onto the surface of the conveyor track 2, so that the detection probes contact the metal contacts of the storage PCB board to conduct electricity, thereby realizing automatic power-on detection of the storage PCB board. The detection method is fast and convenient, and it is easy to realize continuous detection, thus effectively improving the detection efficiency. In addition, the bottom of the detection plate 32 of this embodiment is provided with several insertion holes, and the detection probes can be detachably inserted into the insertion holes. This allows the detection of different storage PCB boards to be realized by adjusting the position of each detection probe, which can expand the applicability of this embodiment.

[0028] And, as Figures 3 to 4 As shown, in order to improve the detection accuracy of the electrical testing mechanism 3, this embodiment also provides an upper lifting component 11 at the position corresponding to the detection board 32 in the conveying track 2. When the storage PCB board is being tested, the upper lifting component 11 can be placed on the bottom of the mold to limit the position of the storage PCB board, thereby facilitating the precise docking of each detection probe with the metal contacts of the storage PCB board to achieve accurate detection. At the same time, it can also support the storage PCB board, thereby avoiding excessive force during the downward pressing of the electrical testing mechanism 3, which could damage the storage PCB board.

[0029] In this embodiment, the upper support assembly 11 includes an upper support cylinder 111 vertically disposed at the bottom of the conveyor track 2 and an upper support plate 112 connected to the output end of the upper support cylinder 111. The width of the upper support plate 112 is adapted to the width of the conveyor track 2, so that when the stored PCB board is being tested, the upper support cylinder 111 can drive the upper support plate 112 to move upward and fit against the bottom of the fixture for storing the PCB board, thereby supporting the stored PCB board. In addition, in this embodiment, baffles 21 are also provided at the positions of the two sides of the top of the conveyor track 2 corresponding to the positions of the electrical testing mechanism 3. When the stored PCB board moves to the testing position via the conveyor track 2, the edge of the fixture loading the stored PCB board can be blocked by the baffles 21, so that when the upper support plate 112 is lifted and fits against the bottom of the fixture, the edge of the fixture can be pushed to fit against the baffles 21, thereby limiting the storage PCB board and improving the testing accuracy.

[0030] like Figure 1 , Figure 2 and Figure 5As shown, after the storage PCB boards are inspected, defective and qualified products can be collected separately by the unloading and collection mechanism. In order to remove the inspected storage PCB boards from the fixture and unload them separately according to the inspection results, this embodiment also includes a transfer mechanism 7 mounted on the chassis 1 above the conveyor track 2. This mechanism can remove the storage PCB boards from the fixture and transfer them to the unloading and collection mechanism according to the inspection results, thereby realizing the automatic sorting and unloading function of this embodiment.

[0031] Specifically, the material collection mechanism of this embodiment includes a defective product collection component 4 for loading defective products, a material unloading component 5 for loading and unloading qualified products, and an upper tray component 6 for supplying empty trays 9 to load qualified products. The defective product collection component 4, the material unloading component 5, and the upper tray component 6 are sequentially arranged on one side of the conveyor track 2 opposite to the electrical testing mechanism 3. The transfer mechanism 7 is arranged across the conveyor track 2 and parallel to the arrangement direction of the defective product collection component 4, the material unloading component 5, and the upper tray component 6. After the stored PCB board has been tested, the transfer mechanism 7 can move along the arrangement direction of each component, thereby transferring the trays 9 supplied by the upper tray component 6 to the material unloading component 5 for batch loading of qualified products. The tested stored PCB board is taken out from the conveyor track 2 and transferred to the defective product collection component 4 or the material unloading component 5 for classification and collection according to the test results, thereby realizing the automatic sorting and unloading function of this embodiment.

[0032] like Figure 5 As shown, the transfer mechanism 7 of this embodiment includes a gantry frame 71 mounted above the conveyor track 2 and a first lifting module 72 and a second lifting module 73 movably mounted on the gantry frame 71. The first lifting module 72 is located on the side of the gantry frame 71 near the upper plate assembly 6, and a first adsorption component 721 is provided at the bottom, which can adsorb the tray 9 supplied by the upper plate assembly 6 and transfer it to the unloading assembly 5 for loading qualified products. The second lifting module 73 is located on the side of the gantry frame 71 near the conveyor track 2, and a second adsorption component 731 is installed at the bottom output end of the second lifting module 73, which can adsorb the storage PCB board that has completed the test in the conveyor track 2 and transfer it to the tray 9 of the defect collection assembly 4 or the unloading assembly 5 for unloading, thereby realizing the automatic sorting and unloading of the storage PCB board.

[0033] Furthermore, in this embodiment, the gantry 71 is arranged parallel to the arrangement direction of the defective product collection component 4, the unloading component 5, and the upper tray component 6. Two sets of parallel transfer drive components 74 are installed on the gantry 71. In this embodiment, the first lifting module 72 and the second lifting module 73 are respectively connected to one of the sets of transfer drive components 74, so that the first lifting module 72 and the second lifting module 73 can move along the gantry 71 under the drive of their respective transfer drive components 74, thereby realizing the transfer of the carrier tray 9 and the storage PCB board respectively. Specifically, the transfer drive assembly 74 in this embodiment includes a drive motor located at one end of the gantry 71 and a conveyor belt connected to the output end of the drive motor and extending to the other end of the gantry 71. The transmission belts of the two sets of transfer drive assemblies 74 are arranged in parallel, and the first lifting module 72 and the second lifting module 73 are respectively connected to the conveyor belt of their respective transfer drive assemblies 74, so that when the drive motor is started, it can drive the transmission belt to rotate, thereby driving the first lifting module 72 and the second lifting module 73 to move along the gantry 71 respectively.

[0034] In addition, both the first adsorption component 721 and the second adsorption component 731 in this embodiment include a connecting frame and multiple sets of negative pressure suction nozzles mounted on the connecting frame. The connecting frame of the first adsorption component 721 is adapted to the structure of the carrier plate 9, while the connecting frame of the second adsorption component 731 is adapted to the structure of the storage PCB board, which facilitates the stable adsorption and transfer of the carrier plate 9 and the storage PCB board.

[0035] like Figure 5 and Figure 6 As shown, the defective product collection component 4 of this embodiment includes a collection bracket 41, a collection channel located on the top of the collection bracket 41, and a collection frame 42 located at one end of the collection bracket 41 and connected to the collection channel. In this embodiment, the collection channel is parallel to the conveyor track 2 and corresponds to the detection position of the stored PCB board. After the second adsorption component 731 adsorbs the stored PCB board of the defective product, it can be directly placed in the collection channel by moving along the gantry frame 71 without any additional action, making the storage method convenient. Furthermore, in this embodiment, a push block 43 is also provided at the end of the collection channel opposite to the collection frame 42, and a push screw module 44 is provided on the collection bracket 41 to drive the push block 43 to move along the collection channel. Under the drive of the push screw module 44, the push block 43 can push the stored PCB board transferred into the collection channel to the collection frame 42 at the other end of the collection channel, realizing the collection and unloading of defective products.

[0036] Furthermore, in this embodiment, a lifting screw module 45 is also provided at the position corresponding to the collection frame 42 inside the chassis 1. The top of the lifting screw module 45 passes through the table surface of the chassis 1 and is connected to the bottom of the collection frame 42, so that the collection frame 42 can move vertically under the drive of the lifting screw module 45. This allows the defective products pushed by the push block 43 to enter the collection frame 42 and be stacked in sequence, thereby realizing the batch collection of defective products without the need to frequently replace the collection frame 42.

[0037] like Figure 1 , Figure 5 and Figure 7 As shown, in this embodiment, an empty tray 9 is supplied by the upper tray assembly 6, and the second adsorption assembly 731 and the transfer drive assembly 74 adsorb and transfer the qualified products to the unloading assembly 5 for loading. In this embodiment, both the upper tray assembly 6 and the unloading assembly 5 include a support tray 51 mounted on the platform of the chassis 1 and a lifting module 52 located inside the chassis 1 and passing through the platform of the chassis 1 to the bottom of the support tray 51. The lifting module 52 can drive the support tray 51 to move upwards, bringing the tray 9 on the support tray 51 closer to the first adsorption assembly 721 or the second adsorption assembly 731. This facilitates the first adsorption assembly 721 to adsorb and transfer the tray 9, and facilitates the second adsorption assembly 731 to place the adsorbed qualified products into the tray 9.

[0038] To achieve automatic loading and unloading of the trays 9, this embodiment also provides two tray conveyor belts 8 on the chassis 1, extending to the bottom of the upper tray assembly 6 and the bottom of the unloading assembly 5, respectively. The other end of the tray conveyor belt 8 is located at the edge of the chassis 1, so that the trays 9 can be transported to the support tray 51 of the upper tray assembly 6 by the tray conveyor belt 8 at the bottom of the upper tray assembly 6, thereby supplying the trays 9. At the same time, the tray conveyor belt 8 at the bottom of the unloading assembly 5 drives the trays 9 on the support tray 51 to the edge of the chassis 1, so as to facilitate collection by the staff.

[0039] Specifically, in this embodiment, the support tray 51 has an opening 53 at the position corresponding to the tray conveyor belt 8, through which the tray conveyor belt 8 passes. When the tray 9 is loaded, the lifting module 52 at the bottom of the upper tray assembly 6 can drive the support tray 51 to move downward, so that the tray conveyor belt 8 passes through the opening 53 and is placed above the support tray 51, thereby transferring the tray 9 to the upper part of the support tray 51. After the lifting module 52 drives the support tray 51 to move upward, it can support the tray 9 and move the tray 9 closer to the first adsorption assembly 721 to achieve tray 9 supply. Conversely, when the tray 9 is full and needs to be unloaded, the lifting module 52 at the bottom of the unloading assembly 5 drives the support tray 51 of the unloading assembly 5 to move downward, so that the tray conveyor belt 8 passes through the opening 53 and fits against the bottom of the tray 9. Thus, the tray 9 can be moved out of the unloading area under the drive of the tray conveyor belt 8 and gradually moved to the edge of the chassis 1, making it convenient for the staff to pick up the material. This realizes the automatic loading and unloading function of the tray 9, which facilitates the fully automatic unloading of the stored PCB board.

[0040] like Figure 1 , Figure 2 and Figure 8 As shown, in this embodiment, the storage PCB boards are loaded using a jig, which facilitates transportation via the conveyor track 2. To facilitate the recycling and storage of empty jigs after the storage PCB boards have been inspected and sorted, this embodiment connects a recycling rack 22 for collecting jigs to the end of the conveyor track 2. A pushing component 23 that moves along the conveying direction of the conveyor track 2 is also provided inside the conveyor track 2. This allows the empty jigs to be automatically collected in the recycling rack 22 after being transported from the conveyor track 2 to the end of the conveyor track 2, pushed by the pushing component 23.

[0041] Specifically, the pushing component 23 in this embodiment includes a pushing motor vertically arranged in the conveying track 2 and a conveyor belt connected to the output end of the pushing motor and extending to the end of the conveying track 2. The conveyor belt is equipped with a mounting base and a push rod hinged to the mounting base. After the fixture is transported to the end of the conveying track 2, the pushing motor can be started to drive the conveyor belt to move, thereby driving the push rod to push the fixture into the recycling rack 22 to realize the collection of the fixture.

[0042] In this embodiment, the push rod is arranged parallel to the transport direction of the conveyor track 2, and a spring is provided at the hinge position between the push rod and the mounting base. The side of the push rod facing the starting end of the conveyor track 2 is an inclined surface lower than the transport plane of the conveyor track 2, while the other end of the push rod is raised above the transport plane of the conveyor track 2 under the action of the spring. When the fixture moves past the push assembly 23, the bottom surface of the fixture moves along the inclined surface of the push rod. At this time, under the action of the hinge with the mounting base, the front end of the push rod gradually moves down and is lower than the transport plane of the conveyor track 2, thereby ensuring the normal transport of the fixture. When the fixture is transported to the end of the conveyor track 2, the end of the push rod used for pushing is automatically raised above the transport plane under the action of the spring. Thus, after the push motor is started, the push rod can abut against the edge of the fixture and push the fixture into the recycling rack 22.

[0043] like Figure 8 As shown, in order to achieve batch collection of the recycling rack 22 and reduce the number of times workers need to pick up materials, this embodiment also installs a double-layered output track 24 at the end of the conveying track 2, and sets a docking conveying component 25 between the output track 24 and the conveying track 2. The recycling rack 22 is installed on the docking conveying component 25. When the recycling rack 22 is fully loaded, the docking conveying component 25 can drive the recycling rack 22 to dock with the upper or lower output track 24 respectively, thereby outputting the recycling rack 22 full of fixtures to the outside of the chassis 1.

[0044] Specifically, the docking and conveying assembly 25 of this embodiment includes a vertically arranged docking lifting module 251 and a conveying platform 252 movably mounted on the docking lifting module 251 and located between the conveying track 2 and the output track 24. A collection rack 22 is mounted on the conveying platform, allowing the collection rack 22 to move up and down under the drive of the docking lifting module 251, thereby driving different height positions of the collection rack 22 to sequentially align with the end of the conveying track 2, achieving the stacking and storage of the fixture. Furthermore, the collection rack 22 can also dock with the two layers of output tracks 24 under the drive of the docking lifting module 251, thereby achieving the output of the collection rack 22. The bottom of the conveying platform in this embodiment is provided with a belt conveyor assembly for driving the collection rack 22 to move into the output track 24. The conveying direction of the belt conveyor assembly is the same as the transport direction of the output track 24, so that after the collection rack 22 docks with the output track 24, the belt conveyor assembly can drive the collection rack 22 to move into the output track 24 to achieve output.

[0045] Furthermore, each lifting module in this embodiment can be a cylinder transmission mechanism or a screw drive mechanism, both of which can realize the lifting and moving functions of each structure. Specifically, the lifting module in this embodiment is set as a screw drive mechanism, which can effectively improve the moving accuracy of each mechanism, thereby realizing the precise sorting and unloading of materials in this embodiment.

[0046] In summary, this embodiment sets up a conveyor track 2, with an electrical testing mechanism 3 and a material collection mechanism on both sides of the conveyor track 2, and a transfer mechanism 7 spanning above the conveyor track 2. After the storage PCB board is processed, it can be transported to the testing position by the conveyor track 2, where it is automatically tested by the electrical testing mechanism 3. The transfer mechanism 7 then transfers the board to the material collection mechanism based on the test results for sorting and collecting defective and qualified products. This achieves automated testing and material collection of the storage PCB board, effectively improving production efficiency and reducing the cost of finished products, while also improving the accuracy of testing, sorting, and material collection.

[0047] Furthermore, by sequentially arranging a defective product collection component 4, a feeding component 5, and an loading component 6 on the side of the conveyor track 2, after the stored PCB board has completed inspection, the loading component 6 can supply the carrier tray 9 and transfer it to the feeding component 5 by the transfer mechanism 7 for batch loading of qualified products. At the same time, the defective product collection component 4 collects defective products, thereby realizing automatic loading of the stored PCB board and improving processing efficiency.

[0048] In addition, by setting tray conveyor belts 8 at the bottom of both the unloading assembly 5 and the upper tray assembly 6, the empty trays 9 can be transported to the upper tray assembly 6 by the tray conveyor belts 8, and then transferred to the unloading assembly 5 by the transfer mechanism 7 for loading qualified products; the fully loaded trays 9 in the unloading assembly 5 can be moved to the outside by the tray conveyor belts 8 for easy collection by staff, thus realizing fully automatic unloading of PCB boards.

[0049] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
