Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment provides a workpiece table capable of fixing a printing workpiece for a pad printing machine, which is particularly suitable for an ink cup type pad printing machine, and can stably and reliably fix the printing workpiece in the workpiece table and effectively prevent the position of the printing workpiece from deviating or even separating from the workpiece table in the process of oil printing.
As shown in fig. 1 and 2, the workpiece stage includes a carrier 1 and a positioning assembly. The upper side of the carrier 1 is provided with a contour groove 11 for accommodating the printing workpiece and 2n guide through grooves 12 which are symmetrically arranged and are respectively communicated with the contour groove 11, wherein n is a positive integer. The positioning assembly is provided with 2n positioning blocks 21 which are respectively arranged corresponding to the 2n guiding through grooves 12 and a power mechanism connected with the 2n positioning blocks 21; 2n positioning blocks 21 surround the carrier 1, and each positioning block 21 is located in the extending direction of the corresponding guiding through slot 12; the power mechanism is used for driving the 2n positioning blocks 21 to simultaneously and respectively move towards or away from the profiling groove 11 along the corresponding guide through grooves 12.
In this embodiment, n is 3, that is, the number of the guiding through grooves 12 on the upper side of the carrier 1, which are the same as the contour grooves 11, is 6, and the number of the positioning blocks 21 is also 6.
In this embodiment, the printing workpiece is a glass mobile phone cover plate. In other embodiments, the print substrate may be other flat or curved or irregularly shaped sheet glass.
In this embodiment, the carrier 1 is a rectangular block structure, and the upper profile groove 11 is rectangular (in other embodiments, it can be made into a corresponding shape according to the shape of the printing workpiece). The distribution mode of the 6 guide through grooves 12 is as follows: 2 respectively with the central authorities intercommunication on two short sides of profile groove 11, 2 spaced-apart with a long avris of profile groove 11 communicates, 2 spaced-apart with another long avris of profile groove 11 communicates.
Thus, after the workpiece table with the structure is used for placing the printing workpieces in the contour groove 11, the 6 positioning blocks 21 of the positioning assembly surrounding the carrier 1 (i.e. surrounding the printing workpieces) can clamp and position the printing workpieces by linearly moving for a proper distance towards the contour groove 11 along the corresponding guide through grooves 12, so that the printing workpieces are prevented from being shifted or even being separated from the contour groove 11 of the workpiece table in the oil printing process. Meanwhile, the 6 positioning blocks 21 move linearly along the corresponding guide through grooves 12 away from the contour grooves 11, and the printing workpiece can be loosened, so that the printing workpiece after finishing oil printing can be taken out conveniently.
Further, the power mechanism comprises a driving module, a transmission disc 22 and a transmission block 23 which are sequentially arranged from bottom to top; the driving module is connected with the transmission disc 22 and is used for driving the transmission disc 22 to rotate around the circle center; referring to fig. 3 to 5, 2m traction holes 221 are symmetrically formed through the transmission disc 22 by taking a circle center as a center, wherein m is a positive integer less than or equal to n; the number of the transmission blocks 23 is 2 m; here, m has a value of 2, i.e., the number of the traction holes 221 and the driving blocks 23 is 4. The 4 driving blocks 23 correspond to the 4 traction holes 221 respectively, the lower side of each driving block 23 is provided with a driving column 233 inserted into the corresponding traction hole 221, the upper side of each driving block 23 is provided with one or more mounting seats 234, and the sum of the number of the mounting seats 234 on all the driving blocks 23 is 6; the 6 positioning blocks 21 are respectively mounted on the upper sides of the 6 mounting seats 234. Specifically, 4 the driving block 23 includes 2 longer first driving blocks 231 and 2 shorter second driving blocks 232, install 2 on the first driving block 231 the mount pad 234, install 1 on the second driving block 232 the mount pad 234. The drawing hole 221 is arc-shaped, and the center of the arc where the drawing hole 221 is located deviates from the center of the transmission disc 22. When the transmission disc 22 rotates forward or backward, the traction hole 221 and the transmission column 233 drive 4 transmission blocks 23 to move linearly towards or away from the center of the transmission disc 22 along the radial direction of the transmission disc 22. Specifically, referring to fig. 4, in fig. 4, the state is shown when the transmission block 23 is located at the position farthest away from the contour groove 11, when the rotating disc rotates in the forward direction (the direction indicated by the curved arrow in the figure), 2 first transmission blocks 231 and 2 second transmission blocks 232 slowly converge towards the center of the transmission disc 22 under the pushing action of the corresponding drawing holes 221, that is, move towards the center of the transmission disc 22 in the radial direction of the transmission disc 22 (the direction indicated by the straight arrow in the figure), obviously, the rotation angle of the transmission disc 22 determines the moving distance of the first transmission blocks 231 and the second transmission blocks 232, so that the proper moving distance of the first transmission blocks 231 and the second transmission blocks 232 towards or away from the center of the transmission disc 22 can be ensured as long as the transmission disc 22 is controlled to rotate in the forward rotation or reverse rotation by the proper angle, and further ensure that the 6 positioning blocks 21 can just clamp the printing workpieces. It is also worth mentioning that the positioning block 21 can be driven to do linear motion by the rotation of the transmission disc 22, so that the linear motion of the positioning block 21 can be alleviated, and the positioning block 21 can be ensured not to generate too large impact on the printing workpiece when moving linearly towards the profile groove 11 and touching the printing workpiece, thereby preventing the printing workpiece from being damaged.
Further, the driving module comprises a base 24 and an air cylinder 25 which are sequentially arranged from bottom to top; one end (rodless side end cover) of the air cylinder 25 is rotatably mounted on the base 24, the other end (piston rod) is rotatably mounted at the non-circle center position of the transmission disc 22, and the extending direction of the piston rod of the air cylinder 25 is parallel to the plane where the transmission disc 22 is located. The driving module further comprises a cam 26, the cam 26 is mounted on the lower side of the transmission disc 22, the center of a base circle of the cam 26 and the center of the transmission disc 22 are on the same straight line perpendicular to the plane of the transmission disc 22, the other end of the air cylinder 25 is rotatably mounted on the lower side of the cam 26, and the distance between the connecting point of the air cylinder 25 and the cam 26 and the center of the base circle of the cam 26 is greater than the radius of the base circle of the cam 26. Thus, the piston rod of the cylinder 25 can extend or retract to drive the transmission disc 22 to rotate reversely or positively. Specifically, referring to fig. 5, when the piston rod of the cylinder 25 extends out to a certain length, the cam 26 can be pushed to rotate forward by a certain angle, the cam 26 drives the transmission disc 22 to rotate forward by the same angle, and the first transmission block 231 and the second transmission block 232 move towards the center of the transmission disc 22 by a certain distance under the driving of the transmission disc 22. In summary, by controlling the stroke of the piston rod of the cylinder 25, the rotation angle of the transmission disc 22 can be adjusted, and the moving distance of the positioning block 21 can be controlled. In addition, the air cylinder 25 is used as a power source, so that the manufacturing cost of the whole workpiece table is reduced. Furthermore, the air cylinder 25 is connected with the transmission disc 22 through the cam 26, and is not directly installed on the transmission disc 22, which not only reduces the manufacturing difficulty of the transmission disc 22, but also prevents the overall strength of the transmission disc 22 from being reduced due to the hole for installing the air cylinder 25 being formed at the position close to the traction hole 221.
Further, the power mechanism further comprises an orientation block 27 (see fig. 1) located above the transmission block 23, and the orientation block 27 is connected and fixed with the base 24 through four upright posts 28. The periphery of the directional block 27 is protruded with a central axis as a symmetric axis to form 6 guide blocks 271, the 6 guide blocks 271 correspond to the 6 guide through grooves 12, and the protruding direction of each guide block 271 is consistent with the extending direction of the corresponding guide through groove 12; the middle part of each mounting seat 234 is provided with a through hole 2341, and the 6 guiding blocks 271 correspondingly extend into the through holes 2341 of the 6 mounting seats 234. A guide rail 2711 is arranged on the lower side of each guide block 271, a guide slider 2712 is embedded on the lower side of the guide rail 2711, and the lower side of the guide slider 2712 is fixedly connected to the transmission block 23 connected with the corresponding mounting seat 234. In this way, the guiding block 271 is matched with the through hole 2341 of the mounting seat 234, so that the transmission block 23 is prevented from rotating in the process of moving under the driving of the transmission disc 22, and the moving direction of the positioning block 21 on the transmission block 23 is ensured to be consistent with the extending direction of the corresponding guiding through groove 12. Moreover, through the matching of the guide rail 2711 and the guide slider 2712, the control of the guide block 271 on the moving direction of the transmission block 23 is more precise and accurate, and meanwhile, the movement of the transmission block 23 is more smooth.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
