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.
[0014] 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.
[0015] 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.
[0016] This utility model provides a reference. Figures 1-3 In this embodiment of the utility model, a loading clamping mechanism for a pneumatic circuit board hot air leveling and soldering machine is applied to the loading mechanism of a four-station rolling circuit board hot air leveling machine. This loading mechanism mainly includes:
[0017] The square-structured feeding rotating frame 3 and the feeding rotating module 1 that drives the feeding rotating frame 3 to rotate; the upper end face of the feeding rotating frame 3 is the board preparation station. When feeding, the circuit board fed in will enter the board preparation station; while the front end face of the feeding rotating frame 3 is the material picking station. After the board preparation station completes the receiving, it is driven to rotate by the feeding rotating module 1, so that the original board preparation station is rotated into a new material picking station, and the circuit board is changed from the original horizontal position to the vertical position, so that the subsequent material picking mechanism can carry out the feeding work of the vertical soldering furnace.
[0018] Each end face of the feeding turntable is equipped with a set of retractable clamping plates; the purpose of which is to clamp the circuit board during the circuit board flipping process.
[0019] The retractable clamping plate device 4 is located at the edge of the end face of the loading turntable 3; the rear end face of the loading turntable 3 is the clamping station. During operation, the retractable clamping plate device 4 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.
[0020] The retractable clamp device 4 includes: a clamp base 41 and a pneumatic lifting seat 44, a pneumatic lifting cylinder 47, a clamp chuck 43 and a pneumatic clamp cylinder 46 installed on the clamp base 41.
[0021] There are at least two sets of clamping heads 43, which are installed on both sides of the pneumatic lifting base 44 (the middle part is located to reserve clamping space for the transfer and picking clamp 23); the piston rod of the pneumatic lifting cylinder 47 is connected to the pneumatic lifting base 44; the pneumatic clamping cylinder 46 and the clamping heads 43 are connected by a linkage rod to realize the opening and closing of the clamping heads 43.
[0022] During operation, the pneumatic lifting seat 44 drives the clamping head 43 to rise, aligning the clamping jaws of the clamping head 43 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 43; the pneumatic clamping cylinder 46 drives the clamping head 43 to close, thus achieving the clamping of the circuit board.
[0023] After the material is picked up, the pneumatic lifting cylinder 47 drives the pneumatic lifting seat 44 to retract, avoiding the loading action of the circuit board.
[0024] Furthermore, the clamping head 43 is composed of a jaw clamping head 47 and a jaw base plate 49. The jaw clamping head 47 is a driving component, and the lower end of the jaw clamping head 47 is hinged to the piston rod of the pneumatic clamping cylinder 46. The clamping surfaces of the jaw clamping head 47 and the jaw base plate 49 are formed with serrated teeth 48 to prevent the clamping plate from loosening or falling off.
[0025] Furthermore, in order to realize the feeding and clamping of the circuit board by the clamping head 43 in the upper plate mechanism, a set of powered roller conveyor 32 is also provided at each end face of the feeding frame 3. During feeding, the circuit board is guided and fed in by the powered roller conveyor 32; and during clamping, the powered roller conveyor 32 outputs reverse power to drive the circuit board back to the clamping position of the clamping head 43.
[0026] The pneumatic lifting seat 44 is equipped with an upwardly extending return baffle 42; when the power roller conveyor 32 drives the circuit board to return, the return baffle 42 precisely blocks the end of the circuit board, forming a precise positioning, ensuring that the clamping head 43 can achieve precise clamping of the circuit board.
[0027] 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.
[0028] 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.
