[0024] Please refer to Figure 1 、 Figure 2 and Figure 3 , this embodiment provides a PCB board loading, unloading, transporting and detecting device 100, which includes a transport frame 110, a testing mechanism 120 and a reflux conveying mechanism 130; the testing mechanism 120 is located on the side edge of the transport frame 110 and is used to detect materials; the transport frame 110 includes an upper frame 111 and a lower frame 112 arranged in a stacked manner; the upper frame 111 is provided with an incoming material line body 1111 and a feeding line body 1112 that are connected in series, and the conveying directions of the incoming material line body 1111 and the feeding line body 1112 are the same, and the feeding line body 1112 is used to output the materials that pass the detection; the upper frame 111 is also provided with a reflux line body 1113, and the conveying direction of the reflux line body 1113 is opposite to that of the incoming material line body 1111, and is used to convey the materials that fail the detection to the reflux conveying mechanism 130; the lower frame 112 is provided with a buffer conveying line body 1121, and the reflux conveying mechanism 130 is arranged at the ends of the reflux line body 1113 and the buffer conveying line body 1121, and the materials can be transferred from the upper frame 111 to the lower frame 112; the buffer conveying line body 1121 is used to output the materials that fail the detection.

[0025] Specifically, as Figure 1 and Figure 2 shown, the PCB board loading, unloading, transporting and detecting device includes a transport frame 110, and the transport frame 110 provides support and layout basis for the transportation of materials; the testing mechanism 120 is responsible for performing various detections on the PCB board materials; the reflux conveying mechanism 130 is used to transfer and process the unqualified materials in the logistics cycle of the entire device.

[0026] The testing mechanism 120 is installed at the side position of the transport frame 110, which is convenient for detecting the materials during the transportation process. It can detect various characteristics of the PCB board, such as circuit connectivity, component soldering quality, dimensional accuracy, etc.

[0027] As Figure 2 shown, the transport rack 110 adopts a stacked design, divided into upper and lower layers, making full use of space and improving the integration of the equipment. The upper rack 111 is mainly responsible for the input of materials, the transportation before detection, and the classified transportation of qualified and unqualified materials after detection; the lower rack 112 is mainly used for caching and finally removing unqualified materials.

[0028] As Figure 3 shown, two interconnected conveyor lines are provided on the upper rack 111. The incoming material line 1111 can continuously transport the PCB board materials to be detected. Optionally, the incoming material line 1111 can be in the form of a conveyor belt, chain or other conveying methods. The incoming material line 1111 transports the materials towards the testing mechanism 120 at a stable speed. When the materials are detected as qualified by the testing mechanism 120, they will be transferred to the feeding line 1112 and then sent out of the equipment to enter the next production process. The conveying directions of these two lines are the same, ensuring the smoothness of the materials during transportation and avoiding the chaos and collision of the materials.

[0029] As Figure 3 shown, in addition to the incoming material line 1111 and the feeding line 1112, a return line 1113 is also provided on the upper rack 111. The return line 1113 is used to transport unqualified materials back to a specific position for subsequent processing. When the materials are detected as unqualified by the testing mechanism 120, they will be placed on the return line 1113. The conveying direction of the return line 1113 is opposite to that of the incoming material line 1111, enabling the unqualified materials to flow back orderly without conflicting with the transportation path of the qualified materials, ensuring the clarity and efficiency of the entire material transportation process.

[0030] As Figure 1 shown, the return conveying mechanism 130 is installed at the very end of the return line 1113. When the unqualified materials are transported to the return conveying mechanism 130 along the return line 1113, it can carry the unqualified materials from the upper rack 111 to the lower rack 112. Optionally, the return conveying mechanism 130 can achieve the vertical handling of materials through equipment such as elevators and manipulators for further processing of unqualified materials.

[0031] As Figure 1As shown in the figure, a buffer conveyor line 1121 is provided on the lower rack 112. When unqualified materials are transferred from the upper rack 111 to the lower rack 112 by the return conveyor mechanism 130, they will be placed on the buffer conveyor line 1121. The buffer conveyor line 1121 can temporarily store and buffer the unqualified materials to avoid material accumulation. Then, these unqualified materials will be gradually removed from the equipment along the buffer conveyor line 1121. In actual production, the staff can regularly collect these unqualified materials and perform corresponding treatments on them, such as re-inspecting after repair or directly scrapping them.

[0032] It should be noted that in an implementable mode of the present application, first, as Figure 3 shown, the incoming material line 1111 includes at least one; when there are multiple incoming material lines 1111, the multiple incoming material lines 1111 are arranged side by side in the first direction, and the first direction is perpendicular to the conveying direction of the incoming material line 1111; the material to be tested is transported to the testing mechanism 120 by the incoming material line 1111, and the testing mechanism 120 is used to test the material to be tested.

[0033] Specifically, the present application does not impose any restrictions on the number of incoming material lines 1111 and the length of each incoming material line 1111. When the production scale expands and higher requirements are placed on the detection efficiency, multiple incoming material lines 1111 can be set.

[0034] Each line can transport PCB boards simultaneously, greatly improving the material input efficiency. In the actual layout, a certain interval distance will be maintained between each incoming material line 1111. This distance should not only ensure that the lines do not interfere with each other but also make full use of the space to ensure the maximum material transportation volume within the limited floor area of the equipment.

[0035] During the transportation process, the material may pass through some auxiliary devices, such as positioning jigs, to ensure that the PCB board is accurately positioned during transportation and does not shift, so as to smoothly enter the testing mechanism 120 for detection.

[0036] Second, as Figure 3 shown, the feeding line 1112 includes at least one; when there are multiple feeding lines 1112, the multiple feeding lines 1112 are arranged side by side in the first direction, and the first direction is perpendicular to the conveying direction of the incoming material line 1111; the testing mechanism 120 tests the material and places the qualified material on the feeding line 1112, and the material qualified by the testing mechanism 120 is removed from the PCB board loading / unloading and transportation and detection equipment 100 through the feeding line 1112.

[0037] Specifically, the number and installation positions of the feeding line bodies 1112 can be correspondingly set with the incoming material line bodies 1111 to improve the material transportation efficiency. During the actual layout, a reasonable distance must be maintained between each feeding line body 1112 to ensure that during operation, the PCB boards on adjacent feeding line bodies 1112 will not collide, scratch, etc., guaranteeing the safe transportation of materials.

[0038] Third, there is at least one reflux line body 1113. When there are multiple reflux line bodies 1113, the multiple reflux line bodies 1113 are arranged side by side in the first direction, and the first direction is perpendicular to the conveying direction of the incoming material line bodies 1111. The materials that have not passed the test by the testing mechanism 120 are conveyed to the reflux conveying mechanism 130 through the reflux line body 1113.

[0039] Specifically, the reflux line body 1113 can be at least one. The reflux line body 1113 can be located at the two side edges of the upper layer frame 111, or can be located between multiple incoming material line bodies 1111 and the outgoing material line body. The present application does not make any restrictions on this.

[0040] The PCB board materials that fail to pass the detection by the testing mechanism 120 can be transported to the reflux conveying mechanism 130 through the reflux line body 1113. During the transportation process, in order to prevent the unqualified materials from shifting, slipping, etc. on the reflux line body 1113, preferably, limit baffles can be installed on both sides of the reflux line body 1113 to ensure that the PCB boards always move on the specified track.

[0041] The stable operation of the reflux line body 1113 ensures the smoothness of the overall material handling process of the equipment. It closely connects the testing link with the subsequent unqualified material handling link, improving the operation stability and reliability of the equipment.

[0042] Fourth, as Figure 1 shown, there is at least one testing mechanism 120. When the number of testing mechanisms 120 is multiple, the multiple testing mechanisms 120 are arranged in sequence along the transportation direction of the transportation frame 110 on the opposite sides of the transportation frame 110.

[0043] In the actual layout, the test mechanisms 120 located on opposite sides of the transport frame 110 can realize the division of labor and cooperation of different types of tests. For example, the test mechanism 120 on the front side is mainly responsible for the detection of electrical performance, such as using high-precision electronic testing instruments to detect the circuit conductivity, resistance, capacitance and other parameters of the PCB board; the test mechanism 120 on the rear side focuses on appearance and size detection, using high-resolution optical detection equipment to check the welding quality of components on the PCB board, the integrity of the circuit, and whether the size of the PCB board meets the standards. Moreover, multiple test mechanisms 120 are arranged in sequence along the transportation direction, so that the materials can pass through different test links in sequence during the transportation process, realizing the streamlined operation of the detection process. This not only improves the detection efficiency, but also ensures the comprehensiveness and accuracy of the detection.

[0044] The above equipment replaces manual transportation and inspection with automated equipment, reducing manual operation intensity and production costs and improving production efficiency.

[0045] For example, Figure 1 and Figure 5 As shown, the PCB board loading and unloading transportation detection equipment 100 also includes a downline conveying mechanism 140, which is located at the end of the buffer conveying line body 1121 along the transportation direction; the downline conveying mechanism 140 includes a first support platform 141, a first conveyor belt 142 and a downline removal unit 143, the downline removal unit 143 and the first conveyor belt 142 are arranged on the first support platform 141, and the downline removal unit 143 is located at the side edge of the first conveyor belt 142; the end of the first conveyor belt 142 away from the conveying direction is connected with the end of the buffer conveying line body 1121; the materials that have not been tested by the testing mechanism 120 are moved to the first conveyor belt 142 via the buffer conveying line body 1121, and are moved out of the PCB board loading and unloading transportation detection equipment 100 by the first conveyor belt 142 via the downline removal unit 143.

[0046] Specifically, in the entire PCB board loading and unloading transportation and testing equipment, in addition to the previously mentioned transport frame 110, test mechanism 120 and other parts, a special offline conveying mechanism 140 is also provided. It is located at the end of the buffer conveying line 1121 along its transportation direction. In a continuously running PCB board production and testing line, unqualified materials are screened out from the test mechanism 120, and then pass through the return line 1113, the return conveying mechanism 130, and then to the buffer conveying line 1121, and finally reach the offline conveying mechanism 140, forming a complete and orderly material processing path.

[0047] like Figure 5As shown, the first support platform 141 provides a stable installation and operation foundation for other components. Preferably, the first support platform 141 is made of solid metal material and has sufficient strength and stability to withstand the weight and vibration generated by the first conveyor belt 142 and the offline removal unit 143 during operation.

[0048] The first conveyor belt 142 is responsible for receiving the unqualified PCB board materials from the end of the buffer conveyor line body 1121 and conveying them toward the offline removal unit 143. Preferably, the first conveyor belt 142 is an endless belt made of rubber or other wear-resistant materials, and the motor drives the rollers to achieve smooth transportation of materials. The offline removal unit 143 is installed on the side of the first conveyor belt 142, and its function is to remove the unqualified materials conveyed from the first conveyor belt 142 out of the equipment. One end of the first conveyor belt 142 is tightly connected to the end of the buffer conveyor line 1121, and the connection method ensures that the material can smoothly transfer from the buffer conveyor line 1121 to the first conveyor belt 142. Preferably, the heights of the two conveyor belts need to be precisely adjusted to be consistent, and the gap between them should be as small as possible to prevent the material from getting stuck or falling during the transfer process.

[0049] PCB materials that are determined to be unqualified by the testing organization 120 will first be transported on the buffer conveyor line 1121. The buffer conveyor line 1121 may convey the materials to the position connected with the first conveyor belt 142 at a certain speed and interval according to the actual production situation. When the material reaches this position, it will be smoothly received by the first conveyor belt 142 and move toward the offline removal unit 143 as the first conveyor belt 142 runs. When the offline removal unit 143 detects that the material has arrived at the specified position, it will start the corresponding action to move the material out of the equipment from the first conveyor belt 142.

[0050] Alternatively, if Figure 1 and Figure 6 As shown, the reflux conveying mechanism 130 has a second support platform 131, a second conveyor belt 132 and a grabbing unit 133. The end of the cache conveyor line 1121 away from the offline conveying mechanism 140 is connected to the second conveyor belt 132. The second conveyor belt 132 is arranged on the second support platform 131, and the grabbing unit 133 is located at the side edge of the second conveyor belt 132. The grabbing unit 133 can move in a vertical direction to grab the material on the reflux line 1113 and place it on the second conveyor belt 132, and transfer it to the cache conveyor line 1121 via the second conveyor belt 132.

[0051] Specifically, Figure 6As shown, the second support platform 131 provides a reliable installation and operation platform for other components. Preferably, the second support platform 131 is made of high-strength metal materials, such as stainless steel or aluminum alloy, and has sufficient rigidity and stability to withstand various forces generated by the second conveyor belt 132 and the grabbing unit 133 during operation, including gravity, friction, and impact force generated when grabbing materials, etc., to ensure that the entire reflux conveying mechanism 130 always maintains a stable state during long-term operation.

[0052] The second conveyor belt 132 is a key carrier for material transmission. It is installed on the second support platform 131, and its function is to receive the materials placed by the grabbing unit 133 and transport the materials to the buffer conveyor line 1121 along a specific direction. Preferably, the second conveyor belt 132 is made of a wear-resistant and flexible material, such as rubber, and the conveyor belt is driven by a motor to drive the roller to circulate, ensuring that the materials can be transported smoothly and continuously.

[0053] The grabbing unit 133 is the part of the return conveying mechanism 130 that is responsible for accurately grabbing the material. It is installed on the side of the second conveyor belt 132 and plays a vital role in the process of handling unqualified materials in the entire equipment. It is responsible for grabbing the unqualified materials on the return line body 1113 and placing them on the second conveyor belt 132.

[0054] like Figure 6 As shown, the second conveyor belt 132 is firmly mounted on the second support platform 131, which not only provides physical support for it, but also ensures the stability of the second conveyor belt 132 during operation. The grabbing unit 133 is located on the side of the second conveyor belt 132, so that the grabbing unit 133 can easily and quickly place the grabbed materials on the second conveyor belt 132, greatly improving the efficiency and accuracy of material transfer.

[0055] The grasping unit 133 has the ability to move flexibly in the vertical direction. When the unqualified materials are transported to the working range of the grasping unit 133 along the return conveyor 1113, the grasping unit 133 moves downward in the vertical direction and uses the grasping components at its front end, such as mechanical grippers or vacuum suction cups, to grasp the materials. Then, the grasping unit 133 moves upward in the vertical direction to lift the materials to a certain height, avoiding the operating area of the return conveyor 1113. Subsequently, the grasping unit 133 moves horizontally above the second conveyor belt 132 and then moves downward in the vertical direction again to smoothly place the materials on the second conveyor belt 132. The second conveyor belt 132 can transport the materials in the direction connecting to the buffer conveyor 1121. When the materials reach the connection between the second conveyor belt 132 and the buffer conveyor 1121, they are smoothly transferred to the buffer conveyor 1121 to continue the subsequent transportation process and finally are removed from the equipment through the offline conveying mechanism 140.

[0056] During the whole process, the precise movement of the grasping unit 133 and its coordinated cooperation with the second conveyor belt 132 ensure that the unqualified materials can be efficiently and accurately transferred from the return conveyor 1113 to the buffer conveyor 1121. Preferably, the grasping unit 133 includes a cylinder and a grasping rod. The output end of the cylinder is connected to the grasping rod, and the cylinder can drive the grasping rod to move in the vertical direction to approach or move away from the buffer conveyor 1121; the grasping rod is used to grasp the materials.

[0057] Furthermore, as Figure 6 shown, the return conveying mechanism 130 further includes a control component 134, and the control component 134 is connected to the second conveyor belt 132; the control component 134 can control the second conveyor belt 132 to move a preset distance at a preset time interval.

[0058] Specifically, the control component 134 can precisely control the second conveyor belt 132 to move a specified distance within a specific time interval. Among them, the preset time interval and the preset distance can be preset according to the material transportation requirements, the requirements of subsequent processing procedures, etc. For example, if the control component 134 controls the second conveyor belt 132 to move 1 meter every 5 seconds, then the second conveyor belt 132 can cooperate with the grasping unit 133 to achieve the orderly arrangement of the materials, ensuring that the unqualified materials can be transported to the buffer conveyor 1121 according to the predetermined rhythm and sequence, providing a strong guarantee for the subsequent processing procedures.

[0059] Exemplarily, as Figure 4As shown in the figure, the testing mechanism 120 includes a body 121 and a robot 122. The body 121 has a detection window 1211, and a detection element for detecting materials is provided inside the detection window 1211; the robot 122 has a gripper 1221, and the gripper 1221 is located on one side of the body 121 and close to the detection window 1211; the robot 122 can rotate relative to the body 121 to transfer the material to be tested on the incoming material line 1111 into the detection window 1211 through the gripper 1221; after the detection element detects the material, the gripper 1221 can transfer the material to the feeding line 1112 or the return line 1113.

[0060] Specifically, the testing mechanism 120, as the core component of the PCB board loading, unloading, transporting and detecting equipment, is composed of two key components: the body 121 and the robot 122. The body 121 is the basic framework and the carrier of the core detection area of the entire testing mechanism 120. It integrates various complex detection elements and circuit systems inside, providing the necessary hardware support and environmental conditions for material detection. The robot 122 is responsible for the precise handling and transfer of materials, enabling the materials to smoothly enter and exit the detection area of the body 121. The two cooperate with each other to jointly complete the detection work of the PCB board materials.

[0061] As Figure 4 shown in the figure, a detection window 1211 is provided on the body 121. The size of the detection window 1211 needs to fully consider the size, shape of the material and the operation convenience during the detection process. Various detection elements for detecting materials are installed inside the detection window 1211, and they can perform various detections on the PCB board materials entering the detection window 1211.

[0062] The robot 122 is equipped with a special gripper 1221. The gripper 1221 is the key component for the robot 122 to grasp and transport materials. The gripper 1221 is located on one side of the body 121 and close to the detection window 1211, enabling the robot 122 to efficiently and quickly transfer the materials into the detection window 1211 when transporting the materials.

[0063] After the material enters the detection window 1211, the detection element starts to conduct a comprehensive inspection on the material. After the inspection is completed, the detection element will feedback the inspection result to the control system of the robot 122. If the material is determined to be qualified, the gripper 1221 of the robot 122 will start again to grab the material out of the detection window 1211. Then, the robot 122 rotates to transfer the material to the feeding line body 1112. The feeding line body 1112 transports the qualified material out of the equipment and into subsequent production processes, such as packaging, assembly, etc. On the contrary, if the material is detected as unqualified, the gripper 1221 of the robot 122 will grab the material and transfer it to the return line body 1113. The return line body 1113 then transports the unqualified material to the return conveying mechanism 130 for subsequent processing, such as repair, scrapping, etc., so as to realize the effective classified transportation of qualified and unqualified materials and ensure the smooth progress of the material handling process of the entire equipment.

[0064] The above are only optional embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0065] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any appropriate way without conflict. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.
