If the number of sheet-shaped workpieces is large, especially for relatively small sheet-shaped workpieces such as crystal oscillators, manual operation is not applicable, and automated equipment needs to be used to flip them to improve the flipping efficiency.

[0003] In the prior art, such as an automatic flipping tooling suitable for side processing of thin plate-like workpieces with the application number 202321965015.2, it can flip multiple workpieces by a certain angle for processing, but it needs to position each workpiece first to ensure its stable position. Another example is an automatic workpiece flipping device with the application number 202321465141.1, which facilitates the flipping and surface conversion operation of the workpiece body through the mutual cooperation between a cylinder, a first motor, a connecting shaft, etc. However, it flips each workpiece with a certain thickness and convenient for side clamping one by one, and the above are not applicable to batch flipping of sheet-shaped workpieces during continuous feeding.

[0028] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0029] As Figures 1 to 4 shown, a flipping device for sheet workpieces includes a machine table 1, and a feeding mechanism 2, a flipping mechanism 3 and a receiving mechanism 4 which are all arranged on the machine table. The feeding mechanism 2 includes a translation module 21 and a carrying component 22. The translation module 21 is arranged on the machine table 1, and the carrying component 22 is arranged on the translation module 21 for feeding sheet workpieces. In combination Figure 5 shown, the sheet workpiece 100 can be a crystal oscillator with a small volume. A plurality of sheet workpieces 100 are arranged in a matrix on the carrying component 22 for batch feeding and flipping. The flipping mechanism 3 includes a mounting frame 30, a first lifting module 31 and a flipping component 32. The mounting frame 30 is of a gantry structure and is arranged on the machine table 1. The first lifting module 31 is arranged on the mounting frame 30. The flipping component 32 includes a mounting plate 321, a first motor 322, a transmission part 323 and an adsorption rod 324. The mounting plate 321 is arranged at the output end of the first lifting module 31. The first motor 322 is arranged on the mounting plate 321 and the transmission part 323 is arranged at the output end. The adsorption rod 324 is rotatably arranged on the mounting plate 321 and is connected to the transmission part 323. The adsorption rod 324 can be driven to move up and down and rotate above the carrying component 22, adsorb the sheet workpiece 100 on the carrying component 22 and drive the sheet workpiece 100 to flip. The receiving mechanism 4 at least includes an adsorption plate 43. After the adsorption plate 43 is docked with the adsorption rod 324, it adsorbs the flipped sheet workpiece 100.

[0030] In the present utility model, the sheet workpiece 100 (such as a crystal oscillator) is loaded onto the carrying component 22 in a matrix. The carrying component 22 is driven by the translation module 21 to drive the sheet workpiece 100 to move to the lower part of the adsorption rod 324 in the flipping mechanism 3. At this time, the ventilation holes (i.e., adsorption holes) on the adsorption rod 324 face the sheet workpiece 100 on the carrying component 22. The first lifting module 31 drives the flipping component 32 to move downwards, so that a plurality of ventilation holes on the adsorption rod 324 respectively abut against the sheet workpiece 100. Through the negative pressure effect of vacuum pumping, the sheet workpiece 100 can be positioned on the adsorption rod 324. The first lifting module 31 drives the flipping component 32 to move upwards. At the same time, the first motor 322 drives the transmission part 323 to drive the adsorption rod 324 to flip 180°, so that the sheet workpiece 100 is located at the upper end of the adsorption rod 324. Then, through the docking with the adsorption plate 43, the adsorption plate 43 adsorbs the sheet workpiece, thereby realizing the 180° flipping of the sheet workpiece 100.

[0031] Further, the material receiving mechanism 4 further includes a linear module 41 and a second lifting module 42. The linear module 41 is arranged on the machine table 1 through a bracket 11, the second lifting module 42 is arranged at the output end of the linear module 41, and the adsorption plate 43 is arranged on the second lifting module 42. In this way, after the adsorption plate 43 adsorbs the sheet-shaped workpiece 100, it can be driven to translate and then move down to place the sheet-shaped workpiece 100 at a specified position or in a tray. Moreover, since the translation module 21 can drive the carrying component 22 to displace a set distance, the second row and the subsequent multiple rows of sheet-shaped workpieces 100 on the crystal oscillator rear row that have been adsorbed on the carrying component 22 can be successively adsorbed, flipped and transferred to the adsorption plate 43 by the flipping mechanism 3, and then the linear module 41 and the second lifting module 42 cooperate to drive the adsorption plate 43 to place the sheet-shaped workpieces 100 at corresponding positions respectively, so that the flipping and blanking of the sheet-shaped workpieces 100 can be carried out quickly and conveniently, thereby improving the processing efficiency of the sheet-shaped workpieces 100.

[0032] The utility model realizes the automatic feeding of the sheet-shaped workpiece 100 through the feeding mechanism 2, adsorbs, flips the sheet-shaped workpiece 100 by 180°, and transfers it upward through the flipping mechanism 3, and then docks the sheet-shaped workpiece 100 to the adsorption plate 43, so that the flipping action of the front and back sides of the sheet-shaped workpiece 100 can be completed quickly and conveniently.

[0033] Preferably, the specific structure of the transmission part 323 can include a driving wheel, a driven wheel and a transmission belt. The driving wheel is arranged at the output end of the first motor 322, the driven wheel is arranged on the adsorption rod 324, and the transmission belt is sleeved on the driving wheel and the driven wheel, and the adsorption rod 324 can be controlled by the first motor 322 to perform a stable and accurate 180° flip.

[0034] Combined Figure 5 and Figure 6 As shown, the adsorption rod 324 includes a bottom rod 3241 and a top rod 3242. A positioning groove 3240 is provided on the bottom rod 3241, and a ventilation groove 324a communicating with an external air source is provided in the positioning groove 3240. A plurality of ventilation holes 324b penetrating through its body are provided on the top rod 3242. The top rod 3241 is arranged in the positioning groove 3240 and the ventilation holes 324b are communicated with the ventilation groove 324a, and the sheet-shaped workpiece 100 is adsorbed through the communication between the ventilation holes 324b and the ventilation groove 324a. The adsorption rod 324 is set in a detachable form of the bottom rod 3241 and the top rod 3242, which is convenient to replace the top rod 3242 with different ventilation hole 324b arrangement structures according to different sizes, arrangement spacings, etc. of the sheet-shaped workpiece 100 and install it on the bottom rod 3241, with better applicability; in addition, a flexible gasket 3243 can be provided on the bottom wall of the positioning groove 3240, and the top rod 3242 abuts against the flexible gasket 3243 to form a better sealing effect.

[0035] Further, the ventilation grooves 324a are in a strip structure, and the number thereof is two. The two ventilation grooves 324a are arranged in parallel, and a partition plate 324c is formed therebetween. Correspondingly, a drainage groove 324d is provided beside each ventilation hole 324b, and the drainage grooves 324d of adjacent pairs of ventilation holes 324b are arranged in a staggered manner, that is, a pair of drainage grooves 324d are parallel but are respectively located on opposite sides of the ventilation holes 324b communicated therewith. A plurality of drainage grooves 324d are connected to the two ventilation grooves 324a at intervals, and the lower end surface of the ventilation hole 324b is arranged opposite to the partition plate 324c, that is, the lower end surface of the ventilation hole 324b is closed by the partition plate 324c. The above setting form can, on the one hand, prevent the ventilation grooves 324a from directly communicating with the ventilation holes 324b, making the negative pressure effect relatively gentle and avoiding excessive force on the crystal oscillator. On the other hand, by respectively connecting the two ventilation grooves 324a to half of the ventilation holes 324b, the adsorption of the plurality of ventilation holes 324b on the sheet workpiece 100 can be made as uniform as possible, avoiding different adsorption forces due to uneven gas flow.

[0036] For another example Figure 4 As shown, the first lifting module 31 includes a second motor 311, a rotating wheel (not shown), an eccentric wheel 312, and a connecting plate 313. The second motor 311 is arranged on the mounting frame 30, and a rotating wheel is provided at its output end. The eccentric wheel 312 is arranged at a non-central position on the rotating wheel. The connecting plate 313 is arranged on the mounting frame 30 in a liftable manner, and is provided with a first horizontal slot 310 in a waist shape. The eccentric wheel 312 is arranged in the first horizontal slot 310 and its upper and lower ends are in contact with the first horizontal slot 310. The mounting plate 321 is arranged on the connecting plate 313. The second motor 311 drives the eccentric wheel 312 to move in the first horizontal slot 310 to drive the connecting plate 313 to move up and down, thereby driving the mounting plate 321 and the components (adsorption rods 324) located on the mounting plate 321 to move up and down. In addition, it should be noted that the second lifting module 42 may have a structure similar to that of the first lifting module 31.

[0037] Preferably, the mounting plate 321 is arranged on the connecting plate 313 in a liftable manner through a guide rail pair, and a spring 33 is hung between the mounting plate 321 and the connecting plate 313, that is, the connecting plate 313 and the mounting plate 321 are not fixedly connected, and relative movement can occur between the two and they can reset themselves. During the process of the connecting plate 313 driving the mounting plate 321 (and the adsorption rod 324) to move downward, after the adsorption rod 324 abuts against the sheet workpiece 100 on the bearing assembly 22, it can float relatively by itself due to the obstruction of the downward movement, avoiding rigid abutment and downward pressure on the sheet workpiece 100 and thus avoiding damage to the sheet workpiece 100. Similarly, relative floating can also be achieved during the docking process of the adsorption rod 324 and the adsorption plate 43 after flipping the sheet workpiece 100.

[0038] Combined withFigure 2 and Figure 3 As shown in Figure 3 , the carrier assembly 22 includes a moving frame 221, a lifting mechanism 222, and a carrier plate 223. The moving frame 221 is slidably disposed on the mounting frame 20 located on the machine table 1 and is disposed at the output end of the translation module 21. The lifting mechanism 222 is disposed on the moving frame 221, and the output end is provided with a carrier plate 223 for carrying the sheet workpiece 100. On the one hand, it can realize the translation of the carrier plate 223 by a set distance to facilitate the accurate positioning of each row of sheet workpieces 100 below the suction rods 324. On the other hand, it can realize the lifting of the carrier plate 223 to facilitate the docking of the sheet workpiece 100 thereon with the suction rods 324.

[0039] Preferably, the lifting mechanism 222 has a structure similar to that of the first lifting module 31 or the second lifting module 42. Specifically, it includes a third motor 2221, a connecting block 2222, a contact wheel 2223, and a contact plate 2224. The third motor 2221 is disposed on the moving frame 221, and the output end is provided with a connecting block 2222. The contact wheel 2223 is disposed on the connecting block 2222 and is not coaxial with the output shaft of the third motor 2221. A plurality of guide sleeves 2241 are provided on the moving frame 221, and a plurality of guide posts 2242 are provided at the lower end of the carrier plate 223. The guide posts 2242 are slidably disposed in the guide sleeves 2241. A contact plate 2224 is provided at the lower end of the carrier plate 223. A second horizontal slot 2220 in a waist shape is provided on the contact plate 2224. The contact wheel 2223 is disposed in the second horizontal slot 2220 and is in contact with the upper and lower ends of the second horizontal slot 2220. Driving the contact wheel 2223 to move in the second horizontal slot 2220 by the third motor 2221 can drive the contact plate 2224 and the carrier plate 223 to move up and down. Moreover, a limit top plate 225 is further provided at the upper end of the moving frame 221 to limit the raised position of the carrier plate 223.
