They 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. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0029] This utility model provides a reference. Figures 1-6In this embodiment of the utility model, the upper plate mechanism of a four-station rolling circuit board hot air leveling and tin spraying machine includes: a whole board feeding belt 1 and a rotating upper plate mechanism 3.

[0030] One end of the whole board feeding belt 1 is the feeding end; during processing, the circuit board is fed in manually from the feeding end, while the other end of the whole board feeding belt 1 is the loading end, which is connected to the rotating loading mechanism 3, and can feed the circuit board into the rotating loading mechanism 3 in sequence.

[0031] The rotating loading mechanism 3 includes: a square-structured loading frame 33 and a loading rotation module 31 that drives the loading frame 33 to rotate; the upper end of the loading frame 33 is a spare board station, which is connected to the loading end of the full board feeding belt 1. During loading, the circuit board fed from the full board feeding belt 1 will enter the spare board station; while the front end of the loading frame 33 is a picking station. After the spare board station completes the receiving, it is rotated by the loading rotation module 31, so that the original spare board station is rotated into a new picking station, and the circuit board is changed from the original horizontal position to the vertical position, so that the subsequent picking mechanism can carry out the feeding work of the vertical soldering furnace.

[0032] Furthermore, a set of powered roller conveyor devices 32 and retractable clamping plate devices 34 are provided at each end face position of the loading frame 33 in the rotating upper plate mechanism 3.

[0033] Each set of powered roller conveyors 32 is an independent operating mechanism. The receiving work of the whole plate feeding belt 1 is realized by the powered roller conveyor 32 at the plate preparation station; while the powered roller conveyors 32 at other stations can be in a stopped state, reducing the overall production energy consumption.

[0034] The retractable clamping plate device 34 is located at the edge of the end face of the loading turntable 33; the rear end face of the loading turntable 33 is the clamping station. During operation, the retractable clamping plate device 34 of the clamping station clamps the circuit board in the spare board station, so that the circuit board in the spare board station can maintain a vertical working state after entering the loading station.

[0035] Furthermore, the retractable clamp device 34 includes: a clamp base 341 and a pneumatic lifting seat 344, a pneumatic lifting cylinder 347, a clamp chuck 343, and a pneumatic clamp cylinder 346 mounted on the clamp base 341.

[0036] There are at least two sets of clamping heads 343, which are installed on both sides of the pneumatic lifting base 344 (the middle part is located to reserve clamping space for the transfer and picking clamp 23); the piston rod of the pneumatic lifting cylinder 347 is connected to the pneumatic lifting base 344; the pneumatic clamping cylinder 346 and the clamping heads 343 are connected by a linkage rod to realize the opening and closing of the clamping heads 343;

[0037] During operation, the pneumatic lifting seat 344 drives the clamping head 343 to rise, aligning the clamping jaws of the clamping head 343 with the circuit board in the preparation station; then, the power roller conveyor 32 outputs reverse power, driving the circuit board back to the clamping jaws of the clamping head 343; the pneumatic clamping cylinder 346 drives the clamping head 343 to close, thus achieving the clamping of the circuit board.

[0038] After the material is picked up, the pneumatic lifting cylinder 347 drives the pneumatic lifting seat 344 to retract, avoiding the loading action of the circuit board.

[0039] Furthermore, the clamping head 343 is composed of a jaw clamping head 347 and a jaw base plate 349. The jaw clamping head 347 is a driving component, and the lower end of the jaw clamping head 347 is hinged to the piston rod of the pneumatic clamping cylinder 346. The clamping surfaces of the jaw clamping head 347 and the jaw base plate 349 are formed with serrated teeth 348 to prevent the clamping plate from loosening or falling off.

[0040] Furthermore, the pneumatic lifting seat 344 is equipped with an upwardly extending return baffle 342; when the power roller conveyor 32 drives the circuit board to return, the return baffle 342 precisely blocks the end of the circuit board, forming a precise positioning, ensuring that the clamping head 343 can achieve precise clamping of the circuit board.

[0041] Furthermore, a set of positioning and centering devices 2 is also provided at the upper end of the preparation plate station of the loading frame 33; the positioning and centering device 2 includes: centering lifting module 21 and two sets of centering moving modules 22 and distance moving modules 24 installed on the centering lifting module 21.

[0042] The centering moving module 22 is located on both sides of the pitch adjusting moving module 24, and the extension direction of the centering moving module 22 is arranged perpendicular to the feeding direction of the power roller conveyor 32.

[0043] The centering moving module 22 is provided with a centering pusher 23; the distance adjusting moving module 24 is arranged perpendicular to the centering moving module 22, and the distance adjusting moving module 24 is provided with a distance adjusting pusher 25.

[0044] When the power roller conveyor 32 feeds the circuit board, the centering lifting module 21 drives the centering pusher 23 and the distance adjustment pusher 25 to descend. The distance adjustment pusher 25 blocks the circuit board. At the same time, the distance adjustment moving module 24 drives the distance adjustment pusher 25 to move towards the center as needed to adjust the position in the feeding direction and prevent it from leaving the standby board station. Then, the centering moving modules 22 on both sides drive the centering pusher 23 to move towards the center to realize the positioning and centering of the circuit board.

[0045] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
