[0036] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0037] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figures 1 to 10 A circuit board drying and loading / unloading device, characterized in that it includes a drying oven 1, with a loading clamp structure 2 and a disassembly clamp structure 3 respectively provided on both sides of the drying oven 1, a clamp return structure 4 provided between the loading clamp structure 2 and the disassembly clamp structure 3, and a circuit board loading structure 5 provided on the outside of the loading clamp structure 2.

[0040] The loading clamp structure 2 includes an assembly robot 21. The assembly robot 21 has a storage and transfer component 22 and an assembly and transfer component 23 on its side, used for storing empty return clamps and for storing assembled circuit board clamps, respectively. The assembly robot 21 is used to move the clamps from the storage and transfer component 22 to the assembly and transfer component 23, and to move the circuit boards loaded by the circuit board loading structure 5 to the clamp position of the assembly and transfer component 23.

[0041] The disassembly clamp structure 3 includes a disassembly manipulator 31. The disassembly manipulator 31 has a disassembly transfer component 32 on its side for placing the dried circuit board clamp assembly. The disassembly manipulator 31 is used to remove the circuit board from the circuit board clamp assembly. The empty clamp with the removed circuit board is moved to the storage transfer component 22 through the clamp return structure 4.

[0042] The assembly robot 21 moves the circuit board input from the circuit board loading structure 5 to the clamp position, and then places the clamp into the oven 1 for baking. After baking, the clamp is taken out and placed in the clamp disassembly structure 3. The clamp disassembly robot takes out the circuit board, and the empty clamp is then moved to the storage and transmission component 22 through the clamp return structure 4, thus completing the circuit board drying and loading / unloading process. At this time, the circuit board is placed in the clamp during the drying process, which can improve the circuit board drying efficiency and realize the semi-automated process of circuit board drying.

[0043] At this time, the circuit board loading structure 5 is used to load the circuit boards, that is, to transfer the circuit boards out in sequence. It adopts the structure in the prior art and does not involve the innovation of this application, so it will not be described in detail here. At this time, the circuit board loading structure 5 is equipped with an output conveyor belt. Alternatively, a separate output conveyor belt can be set on the side of the storage and transmission component 22, located on the side of the circuit board loading structure 5 and aligned with the conveyor belt of the circuit board loading structure 5, so as to receive the circuit boards transferred out in sequence by the circuit board loading structure 5. This makes it convenient for the assembly robot 21 to take out the circuit boards.

[0044] Since the circuit boards are placed in the clamp for drying, to avoid damage to the circuit boards, partitions need to be placed between adjacent circuit boards to separate them. Specifically, in this embodiment, the clamping structure 2 and the clamping structure 3 also include a partition assembly 6, which is used to store and collect the partitions, respectively. The partition assembly 6 includes a first support plate 61 for placing the partitions. The side of the first support plate 61 is connected to a fixed side plate 62 through a guide rail slider structure. A lifting structure 63 is provided between the first support plate 61 and the fixed side plate 62 to control the up and down movement of the first support plate 61. Outer baffles 64 are provided on both sides of the first support plate 61. The first support plate 61 is provided with a vertical through guide rod 65. The guide rod 65 and the outer baffles 64 form a first receiving space for accommodating the partitions. Multiple partitions are placed on the first support plate 61 in the partition assembly 6 on the side of the loading clamp structure 2. Under the action of the lifting structure 63, the first support plate 61 moves up and down, so that the partitions located at the top are always at the same height, which makes it convenient to take out or place the partitions. At this time, the lifting structure 63 adopts a motor screw structure, that is, the motor controls the screw to rotate, and a sliding joint is sleeved on the outside of the screw. The sliding joint is fixed to the first support plate 61. When the motor controls the screw to rotate, the sliding joint can move up and down, thereby controlling the up and down movement of the first support plate 61.

[0045] The first support plate 61 is provided with a vertical through guide rod 65. The guide rod 65 and the outer baffle 64 form a first receiving space for accommodating the partition. At this time, the guide rod 65 can be used to guide the first support plate 61 during its up and down movement, and can also be used to limit the position of the partition. That is, by forming a first receiving space for placing the partition with the outer baffle 64 through the guide rod 65, the partition will not shift, thereby ensuring that the partition is kept in the same position and will not tip over, thus ensuring stability during the movement.

[0046] The assembly and transfer assembly 23 is used for assembly, that is, placing circuit boards, partitions, etc. in the clamp position. At this time, the assembly and transfer assembly 23 includes an assembly conveyor belt 231. The assembly conveyor belt 231 is provided with several lifting components 232 in the middle. The adjacent lifting components 232 are provided with blocking components 233. The clamp is located on the upper side of the lifting components 232, and the adjacent clamps are separated by the blocking components 233. After reflow, the clamp first moves to the storage and transmission component 22. Then, under the action of the assembly robot, the clamp is moved to the assembly conveyor belt 231. During the assembly process, the clamp needs to remain stationary to prevent the circuit boards and partitions from shifting during placement. Therefore, a blocking component 233 is provided. The blocking component 233 first moves upward above the assembly conveyor belt 231 to block the clamp from moving further. Then, the lifting component 232 lifts the corresponding clamp, preventing it from moving with the assembly conveyor belt 231. This facilitates the placement of circuit boards and partitions. Furthermore, after the clamp has placed the circuit boards and partitions, it can continue to move forward. The blocking component 233 can also separate adjacent clamps to facilitate their subsequent removal.

[0047] Specifically, the lifting assembly 232 includes a lifting cylinder, a lifting plate connected to the piston rod of the lifting cylinder, and a limiting block on the side of the lifting plate. The lifting plate moves up and down under the action of the lifting cylinder to lift the clamp that has moved to the upper position on the lifting plate and separate it from the assembly conveyor belt 231. Under the action of the lifting cylinder, the lifting plate moves up and down, thereby separating the clamp at the upper position from the assembly conveyor belt 231. The clamp then stays on the upper side of the lifting plate, facilitating the placement of circuit boards and partitions.

[0048] Specifically, the blocking assembly 233 includes two vertically arranged blocking cylinders, correspondingly distributed on the inner side of the assembly conveyor belt 231. The piston rod of each blocking cylinder is connected to a top block. When the top block moves upward, it is positioned between two adjacent clamps, separating them. Under the action of the blocking cylinders, the top block moves up and down, raising it above the upper side of the assembly conveyor belt 231, thus preventing the moving clamps from continuing to move. This ensures that the clamp's position is determined when the lifting assembly 232 lifts it, thus providing positioning for the clamps. Furthermore, when multiple clamps are on the upper side of the assembly conveyor belt 231, the top block can separate adjacent clamps, facilitating subsequent removal of the clamps.

[0049] The clamp is used to hold circuit boards and partitions. During the drying process, the clamp is moved together with the oven 1. Therefore, in this embodiment, the clamp includes a base plate 71. The base plate 71 has three continuous sides with vertical plates 72. The vertical plates 72 are U-shaped with an opening on one side. The side of the opening has an extending blocking part 73. The top of the vertical plate 72 has an outwardly bent part. At the same time, the vertical plate 72 has several holes or slots, which allows circuit boards in different positions to communicate with the outside through the side, thereby improving the drying efficiency of the circuit boards.

[0050] The assembly robot 21 and the disassembly robot 31 are used to move circuit boards and partitions. In this embodiment, the assembly robot 21 and the disassembly robot 31 include a multi-axis robot and a machine head 8. The machine head 8 includes a movable plate 81 fixed to the multi-axis robot. The movable plate 81 has a first movable structure 82 and a second movable structure 83 on both sides. The first movable structure 82 includes a first vertical cylinder 821. The piston rod of the first vertical cylinder 821 is connected to a suction cup 822 through a first bracket. The second movable structure 83 includes a second vertical cylinder 831. The piston rod of the second vertical cylinder 831 is connected to a second bracket. A horizontally arranged clamping cylinder 832 is provided on the outside of the second bracket. The piston rod of the clamping cylinder 832 is connected to a pin 833 through a horizontal bracket. The multi-axis robot can rotate five or six axes according to actual needs. The robot head 8 is used to fix the circuit board and partition. At this time, the circuit board and partition are fixed by the suction cup 822. The suction cup 822 is a vacuum suction cup 822, which is connected to a vacuum generator. This can prevent damage to the circuit board when fixing it.

[0051] During the drying process, to ensure the drying effect, a counterweight 9 needs to be added on top to ensure that all circuit boards are under pressure. Specifically, the circuit board drying and unloading equipment also includes a counterweight 9. The counterweight 9 has a fixing hole corresponding to the pin 833. The assembly robot 21 or the disassembly robot 31 moves the counterweight 9 to the clamping position or removes the counterweight 9 from the clamping position. After the circuit board and partition are placed into the clamping position, the counterweight 9 needs to be placed on top. Specifically, the clamping cylinder 832 of the assembly robot 21 controls the lateral movement of the pin 833, which inserts into or pulls out of the fixing hole of the counterweight 9. This fixes or separates the counterweight 9 from the clamping position, thus completing the movement of the counterweight 9.

[0052] After drying is complete, the clamps are removed manually or by other equipment and placed in the dismantling conveyor assembly 32 of the clamp dismantling structure 3. Specifically, the dismantling conveyor assembly 32 includes a collecting conveyor belt 321 for placing the dried clamps and empty clamps. The collecting conveyor belt 321 has a discharge conveyor belt 33 on its side for placing the dried circuit boards. At this time, the removal equipment adopts the existing technical solution, so it will not be described in detail here. After the dried clamps are removed, they are placed in the collecting conveyor belt 321. Then, the counterweight 9 is removed by the dismantling robot 31. Then, the circuit boards and partitions are removed. The circuit boards are placed on the upper side of the discharge conveyor belt 33, and the partitions are placed on the upper side of the corresponding first bearing plate 61. After all the circuit boards and partitions are removed, the clamps are empty and can be returned.

[0053] During the return process, the empty clamp after the circuit board and partition have been removed and dried is moved to the assembly conveyor belt 231. Specifically, in this embodiment, the clamp return structure 4 includes a return conveyor belt 41, with connecting platforms 42 at both ends. Each connecting platform 42 includes a rotary motor 421, the shaft of which is connected to a rotating plate 422. A lower moving plate 423 is connected to the upper guide rail slider structure of the rotating plate 422, and a third conveyor belt 4 is mounted on the upper side of the lower moving plate 423 via a third bracket. 24. A return lifting cylinder is provided in the middle of the third conveyor belt 424. The piston rod of the return lifting cylinder is connected to the return top plate 425. The lower moving plate 423 rotates by an angle under the action of the rotary motor 421, so that the third conveyor belt 424 of one docking platform 42 is aligned with the return conveyor belt 41 or the assembly conveyor belt 231, and the third conveyor belt 424 of the other docking conveyor belt is aligned with the return conveyor belt 41 or the collection conveyor belt 321, for moving the empty bin clamp from the collection conveyor belt 321 to the assembly conveyor belt 231. At this time, the connecting platform 42 is used to change the transmission direction of the clamp, so that the empty clamp moves from the collection conveyor belt 321 to the assembly conveyor belt 231. At this time, the lower side of the rotating plate 422 is connected to the worktable through the guide rail slider structure. The guide rail on the worktable is parallel to the direction of the return conveyor belt 41 and is equipped with a corresponding drive structure (motor screw structure) to control the rotating plate 422 to move along the direction of the guide rail, so that the third conveyor belt 424 at the upper position moves closer to the return conveyor belt 41, which facilitates the transmission of the clamp. At the same time, a rack is provided on the side of the rotating plate 422, and a motor is provided on the lower moving plate 423. The motor shaft is equipped with a gear, which meshes with the rack. So, during the rotation of the motor shaft, the rotating plate 422 is fixed, and the lower moving plate 423 moves along the corresponding guide rail direction, so that the third conveyor belt 424 on the upper side of the lower moving plate 423 is aligned with the assembly conveyor belt 231 or the collection conveyor belt 321, so that the clamp can move.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
