Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning equipment for the production of electronic crystal oscillators, and particularly relates to a workpiece tray flipping mechanism. Background Technology

[0002] Small-sized crystal oscillators and other components are neatly arranged on trays during production and switched between various processes. After undergoing soldering and high-temperature heating processes, the trays are prone to accumulating contaminants such as solder slag and dust, requiring timely cleaning. During ultrasonic cleaning, both the top and bottom surfaces of the trays need to be cleaned. However, existing cleaning equipment can only clean one side at a time, requiring manual flipping before cleaning the other side. This manual operation is significantly inefficient and costly. Therefore, a flipping mechanism needs to be designed to achieve automatic flipping and improve efficiency. Summary of the Invention

Detailed Implementation

[0008] like Figures 1 to 3As shown, this utility model describes a workpiece tray flipping mechanism, used for ultrasonic cleaning of workpiece trays. After cleaning one side of the tray, the tray is flipped to clean the other side. The flipping mechanism includes a main support 1, a flipping motor 11 mounted on the main support 1 and its output flipping shaft 12, and a main flipping frame 2 connected to the flipping shaft 12. The main flipping frame 2 has a flipping arm 21 connected to the output flipping shaft 12, an inner connecting plate 22 connected to the flipping arm 21 and parallel to the axial direction of the output flipping shaft 12, and two connecting plates to the inner connecting plate 22. Two end plates 23 are connected at one end and are perpendicular to the output flip shaft 12. A longitudinally arranged parallel gripper cylinder 24 is installed on the inner side of each of the two end plates 23. The output ends of the parallel gripper cylinders 24 on the two end plates 23 face each other. A longitudinal guide rail mounting plate 241 is fixed to the outer side of the cylinder body of each parallel gripper cylinder 24, and a pair of longitudinal guide rails 242 are installed on each longitudinal guide rail 241. Each longitudinal guide rail 242 is provided with an upper slider 243 and a lower slider 244. The same longitudinal guide rail... An upper mounting plate 25 is connected to an upper slider 243 on the longitudinal guide rail 242 of the rail mounting plate 241, and an upper transverse guide rail 251 is provided on the upper mounting plate 25. A lower mounting plate 26 is connected to a lower slider 244 on the longitudinal guide rail 242 of the same longitudinal guide rail mounting plate 241, and a lower transverse guide rail 261 is provided on the lower mounting plate 26. A longitudinal hollow part 245 is provided in the middle of the longitudinal guide rail mounting plate 241. The upper mounting plate 25 and the lower mounting plate 26 pass through a back connector (not shown due to obstruction of view in the figure) respectively. The longitudinal hollow section 245 is connected to the output end of the parallel gripper cylinder 24; that is, the output ends of the two parallel gripper cylinders 24 respectively drive the two sets of upper mounting plates 25 and lower mounting plates 26 to move up and down along the longitudinal guide rail 242. The upper mounting plates 25 and lower mounting plates 26 in turn drive the upper transverse guide rail 251 and lower transverse guide rail 261 to move up and down respectively, so as to realize the upper transverse guide rail 251 and lower transverse guide rail 261 on the same side to move together or separate. The upper transverse guide rail 251 and lower transverse guide rail 261 are longer than the upper mounting plate 25 and lower mounting plate 26. The upper transverse guide rail 251 and the lower transverse guide rail 261 are respectively provided with a left slider 252 and a right slider 253 at both ends. Each left slider 252 and the right slider 253 is connected to a guide block 254 on its back. Each guide block 254 is connected to a guide wheel 255 (the guide wheel 255 can also be replaced by a guide post). On both sides of each longitudinal guide rail mounting plate 241, a track plate 246 is also provided. Each track plate 246 is provided with guide grooves 247 that cooperate with the guide wheel 255 at the top and bottom. Each guide groove 247 is arranged symmetrically at the top and bottom. The middle section of the guide groove 247 is a vertical section and the two ends are arc-shaped sections extending outward. Upper clamping frame 27 is connected to the outer ends of the guide blocks 254 at both ends of the upper transverse guide rail 251, and upper clamping plate 271 is provided on the inner side of the upper clamping frame 27; lower clamping frame 28 is connected to the outer ends of the guide blocks 255 at both ends of the lower transverse guide rail 261, and lower clamping plate 281 is provided on the inner side of the lower clamping frame 28, and upper clamping plate 271 and lower clamping plate 281 are arranged opposite to each other. In this embodiment, the upper clamping frame 27, the lower clamping frame 28, and the upper clamping plate 271 and lower clamping plate 281 on them are arranged symmetrically from top to bottom. At the same time, the components on the inner side of the two end plates 23 are also arranged symmetrically with respect to the center line of the clamping frame. The components on the inner side of the same end plate 23 are also arranged symmetrically from left to right and from top to bottom with respect to the center line of the end plate 23, thereby achieving precise clamping and releasing action effects.

[0009] Through the cooperation of the slider on the transverse guide rail, the guide block, the guide wheel and the guide groove on the track plate, when the transverse guide rail moves up and down with the upper and lower mounting plates, the left and right sliders, the guide block and the guide wheel also move up and down, thereby driving the upper clamping frame and the lower clamping frame to move up and down and horizontally, so that the upper clamping plate and the lower clamping plate can perform clamping and releasing actions.

[0010] Clearance holes 272 are provided at both ends of the upper clamping frame 27 and the lower clamping frame 28, allowing the ends of the upper transverse guide rail 251 and the lower transverse guide rail 261 to pass through; so that the upper and lower clamping frames will move along the transverse guide rail with the guide block 254 and the left slider 252 and the right slider 253 to expand or shrink the range of the clamping frame. An outer frame plate 29 is also connected to the outer ends of the two end plates 23 to make the entire main flip frame structure more complete and stable; An inner protective plate 231 bent inward is installed on the upper and lower edges of each end plate 23. The upper transverse guide rail 251, the lower transverse guide rail 261, the upper mounting plate 25, the lower mounting plate 26, the left slider 252, the right slider 253, the longitudinal guide rail mounting plate 241, the track plate 246, and the parallel gripper cylinder 24 are all located inside the inner protective plate 231. The upper surface of the inner protective plate 231 is provided with a hollow part 232 through which the air nozzle of the parallel gripper cylinder 24 passes.

[0011] In use, the flipping mechanism is installed between the tray receiving platforms of two sets of cleaning mechanisms (not shown in the figure). After one set of cleaning mechanisms completes the cleaning of one side of the workpiece tray 3, it is moved to the tray receiving platform with its four sides suspended. At this time, the upper clamping frame 27 and the lower clamping frame 28 of the flipping mechanism are in the open state, that is, the guide wheels 255 on the guide block 254 are located at the two ends of the guide groove 247. Under the drive of the flipping motor 11, the main flipping frame 2 of the flipping mechanism makes the workpiece tray 3 located between the upper clamping frame 27 and the lower clamping frame 28. Within the area of ​​the holding frame 28 and the upper clamping plate 271 and lower clamping plate 281; then, when the two parallel gripper cylinders 24 synchronously drive the upper mounting plate 25, the lower mounting plate 26 and the upper transverse guide rails 251 and 261 on them to move towards each other, the guide wheel 255 moves simultaneously in the vertical and horizontal directions under the guidance of the guide groove 247, gradually closing up and down and shrinking inward so that the inner ends of the upper clamping plate 271 and the lower clamping plate 281 are located directly above and directly below the edge of the workpiece tray 3, and further in the vertical section of the guide groove 24. Under the constraint of 7, the upper clamping plate 271 on the upper clamping frame 27 and the lower clamping plate 281 on the lower clamping frame 28 close vertically to clamp the edge of the workpiece; then the flipping motor 11 drives the entire main flipping frame 2 to flip the workpiece tray 3 180 degrees, so that the workpiece tray 3 flips to the tray receiving platform on the other side; then the upper transverse guide rail 251 and the lower transverse guide rail 261 move in opposite directions, and the guide wheel 255 first opens along the vertical section of the guide groove 247. At this time, the upper clamping plate 271 of the upper clamping frame 27 and the lower clamping plate 281 of .... When plate 281 releases the workpiece tray 3, and the guide wheel 255 moves to the arc-shaped sections at both ends of the guide groove 247, the guide wheel 255 drives the left and right sliders to move outward, which in turn drives the upper clamping frame 27 and the lower clamping frame 28 to move outward, which in turn causes the upper clamping plate 271 and the lower clamping plate 281 to also move outward, further away from the area where the workpiece tray is located, so that there is enough space to reverse and flip back to the original position for the next flip and transfer; while the workpiece tray remains on the tray receiving platform on the other side, and is transferred by the cleaning mechanism for cleaning on the other side.

[0012] In summary, the flipping mechanism of this utility model can achieve a 180° flipping transfer of the workpiece tray, allowing the tray to be flipped over and transferred to the next set of cleaning mechanisms for cleaning, thereby replacing manual operation, improving work efficiency and saving labor costs.

[0013] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
