Description

Technical Field

[0001] This application relates to the field of glass processing technology, and in particular to a controllable feeding rack for a cover plate screen printing machine. Background Technology

[0002] A cover glass screen printing machine is a type of screen printing machine specifically designed for printing on flat materials such as glass covers, acrylic, and PC. Its core function is to transfer ink onto the substrate surface through a screen, enabling multi-color printing, halftone printing, and other processes. In the manufacturing and processing of optical glass, cover glass screen printing machines effectively enhance the visual appeal of the glass. When used as a screen, processing with a cover glass screen printing machine can significantly improve the glass's light transmittance and protect it from daily corrosion, extending the lifespan of the optical glass.

[0003] In existing technologies, glass is typically placed manually onto the processing station of a cover glass screen printing machine. During placement, the glass inevitably rubs against the parts of the machine due to various external factors. As optical glass requires high clarity, this friction can cause blurred areas on the glass, affecting its transparency. Therefore, there is an urgent need in the market for a controllable loading rack for optical glass on cover glass screen printing machines. Utility Model Content

[0004] In order to reduce the friction between the optical glass and the parts during the loading process of the cover screen printing machine, maintain the surface transparency of the optical glass, and simplify the glass loading process of the cover screen printing machine, this application provides a controllable loading rack for the cover screen printing machine.

[0005] The controllable feeding rack for a cover plate screen printing machine provided in this application adopts the following technical solution:

[0008] Linkage 1, there are two links, which are symmetrically hinged to both sides of the extension seat;

[0009] The mounting frame includes a fixed frame and two clamping rods that are slidably embedded in the fixed frame along the length direction for jointly clamping the glass. The fixed frame is symmetrically equipped with drive cylinders that are respectively connected to the two clamping rods.

[0010] Link 2, there are two links, which are symmetrically hinged to both sides of the extension seat. The hinged end of link 2 is located on the same horizontal plane as the hinged end of link 1. The distance between link 2 and link 1 on the same side of the extension seat is equal to the width of the fixing frame.

[0011] A drive wheel is fixedly connected to the hinged end of the first connecting rod. A drive motor connected to the drive wheel is mounted on the extension seat to drive the first connecting rod to rotate.

[0012] The other ends of the two connecting rods are symmetrically hinged to the fixed frame on the side away from the connecting rod, and the mounting frame always remains horizontal.

[0013] Optionally, the extension base has an extension shaft symmetrically and integrally connected on both sides. The two connecting rods are respectively hinged to the ends of the extension shafts. The minimum distance between the two connecting rods is greater than or equal to the maximum distance between the two connecting rods. Both connecting rods are electrically controlled telescopic rods. When the length of the connecting rod is greater than that of the connecting rod, the mounting frame is in a flipped state.

[0014] Optionally, two auxiliary plates are slidably disposed on the fixing frame at the position of each clamping rod. The two auxiliary plates are respectively attached to both sides of the clamping rod along the height direction. Both auxiliary plates are connected to an adjusting cylinder. When the fixing frame is on a horizontal plane, one of the auxiliary plates located on the bottom side of the clamping rod extends the clamping rod into the fixing frame.

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses a controllable feeding rack for a cover plate screen printing machine.

[0030] Reference Figure 1 A controllable feeding rack for a cover plate screen printing machine, comprising:

[0031] Extension seat 1 is fixed to one side of the feeding station on the screen printing machine 8.

[0032] There are two connecting rods 1 and 2, which are symmetrically hinged to both sides of the extension seat 1 along the width direction. The two connecting rods 1 and 2 can rotate synchronously.

[0033] Mounting frame 3 is a frame structure, specifically including a fixing frame 31 and clamping rods 32. There are two clamping rods 32, which are symmetrically slidably embedded in the inner side of the fixing frame 31 along its length. Two drive cylinders 33 are symmetrically fixedly mounted on the fixing frame 31, each driving one of the clamping rods 32 to move towards the other. When the equipment is working, the two clamping rods 32 move closer together under the drive of the drive cylinders 33 to clamp both sides of the optical glass to be processed.

[0034] There are two connecting rods 4, which are symmetrically hinged to both sides of the extension seat 1. The hinged ends of connecting rods 4 and 2 are on the same horizontal plane. The other ends of the two connecting rods 4 away from the extension seat 1 are also hinged to the mounting frame 3 and to the side of the fixed frame 31 away from connecting rod 2, so as to cooperate with connecting rod 2 to support the entire mounting frame 3.

[0035] The extension base 1 is equipped with drive wheels that rotate synchronously with the two connecting rods 2 at their hinge positions, and these drive wheels are connected to drive motors. The drive motors can drive the two connecting rods 2 and the two connecting rods 4 to rotate together, thereby moving the optical glass from the placement station to the processing station.

[0036] Since the structure of driving the connecting rod 2 to rotate around the extension shaft 11 by the drive wheel and drive motor is a simple transmission structure in the field of mechanics, in order to highlight the solution of this application and simplify the structure, the drive wheel and drive motor will not be shown in the drawings. Those skilled in the art can easily understand the working principle of the drive wheel and drive motor without creative effort.

[0037] To ensure that the mounting bracket 3 remains horizontal and to prevent the glass from colliding or scratching with other structures during movement, this application designs the distance between the connecting rod 2 and the connecting rod 4 on the same side of the extension seat 1 to be equal to the width of the mounting bracket 3, so that the mounting bracket 3 can always maintain horizontal movement.

[0038] Reference Figure 1 Furthermore, the two sides of the extension base 1 are symmetrically and integrally connected with extension shafts 11, and two connecting rods 4 are respectively hinged to the ends of the two extension shafts 11 away from the extension base 1. The minimum distance between the two connecting rods 4 is greater than the maximum distance between the two connecting rods 2, so that when connecting rods 2 and 4 coincide in the vertical plane, it will not affect the normal movement between connecting rods 2 and 4. Both connecting rods 2 and 4 are electrically controlled telescopic rods, which can change their length.

[0039] Under normal conditions, the lengths of connecting rod 2 and connecting rod 4 are equal, ensuring that the glass remains horizontal. When processing the other side of the glass is required, connecting rod 4 is driven to a length greater than connecting rod 2. The length changes of connecting rods 2 and 4 are always maintained to ensure that the mounting bracket 3 remains horizontal. This design allows the screen printing machine 8 to quickly and conveniently process both sides of the optical glass, improving processing efficiency.

[0040] Reference Figure 2 Two auxiliary plates 5 are slidably mounted on both sides of the two clamping rods 32 along the thickness direction on the fixing frame 31. These plates are used to assist in supporting the glass and prevent the glass from falling and breaking if the clamping rods 32 malfunction and become loose. Both auxiliary plates 5 are connected to adjusting cylinders, which are fixed to the fixing frame 31.

[0041] When the fixing frame 31 is on a horizontal plane and the two clamping rods 32 on it clamp the glass together, the auxiliary plate 5 extends into the inside of the fixing frame 31 and abuts against the bottom of the glass to achieve the purpose of assisting in lifting.

[0042] Reference Figure 2 Furthermore, the auxiliary plate 5, at the end furthest from the adjusting cylinder, has a ramp 51 near the clamping rod 32, and the bottom of the ramp 51 is flush with the side of the auxiliary plate 5 furthest from the clamping rod 32. When the glass is placed at the processing station, the ramp 51 allows the glass to slowly move down along the surface of the ramp 51 and fall to the predetermined position, preventing the glass from shifting position or being damaged during the fall due to height differences. The ramp 51 also makes it easier to lift one of the stacked glass pieces when clamping it.

[0043] Reference Figure 2 Furthermore, rubber pads 52 are laid on both the side of the auxiliary plate 5 near the clamping rod 32 and on the ramp 51, and the surface of the rubber pads 52 is smooth. The rubber pads 52 can ensure that the surface of the glass is not abraded when sliding and when it comes into contact with the auxiliary plate 5, thus maintaining the integrity of the glass's surface transparency.

[0044] Reference Figure 1 and Figure 3 The extension seat 1 is equipped with a rotation locking mechanism 6 at the positions of the two connecting rods 1 2. The rotation locking mechanism 6 can fix the connecting rods 1 2, 4 and the mounting frame 3 at a predetermined rotation angle, making the structure of the loading rack more stable when installing or unloading glass and preventing shaking. At the same time, it allows the operator to control the position of the mounting frame 3 at will, improving the overall controllability of the device.

[0045] Specifically, the rotary locking mechanism 6 includes a positioning disk 61, a locking pin 62, and a ring coil 63, wherein the positioning disk 61 is fixedly connected to the extension seat 1. A groove 21 is formed along the length of the connecting rod 2 on the side away from the extension seat 1, and one end of the locking pin 62 is slidably engaged in the groove 21. A tension spring 64 is installed on the side wall near the hinge end of the groove 21, while an energized ring coil 63 is installed on the side wall at the other end, and the ring coil 63 is electrically connected to a discharge device. The locking pin 62 is ferromagnetic and connected to the tension spring 64 on one side, and can slide within the groove 21 under the drive of the tension spring 64 and the ring coil 63. Several locking grooves 611, which are sized to match the locking pin 62, are equally spaced along the circumference of the positioning disk 61, and one of the locking pins 62 is engaged in a locking groove 611.

[0046] When it is necessary to keep the mounting bracket 3 stationary, by de-energizing the annular coil 63, the locking pin 62 will enter the locking groove 611 under the pull of the tension spring 64, thereby achieving rotational locking of the connecting rod 2.

[0047] When the mounting bracket 3 needs to be moved, by energizing the annular coil 63, the induced magnetic force generated by the annular coil 63 will attract the locking pin 62 to disengage from the locking groove 611 on the positioning plate 61, at which time the connecting rod 2 can rotate freely.

[0048] Reference Figure 3 Furthermore, the depth of the locking groove 611 is preferably greater than the radius of the locking pin 62 and smaller than the diameter of the locking pin 62, so that the locking pin 62 can move a small distance to achieve the above-mentioned effect, saving energy consumption and materials used in the manufacture of the device. Moreover, this structure allows the connecting rod 2 to forcibly release itself from its lock by applying a large force in an emergency.

[0049] Reference Figure 1 Preferably, a stacking tray 7 is placed on one side of the extension seat 1, on which multiple pieces of glass are stacked, and a lifting cylinder 71 is installed on the bottom side of the stacking tray 7. The lifting cylinder 71 can move the glass stack upwards by one station each time, realizing automatic glass feeding, further saving manpower consumption, and improving the processing efficiency of the screen printing machine 8.

[0050] The implementation principle of the controllable feeding rack for a cover plate screen printing machine according to the embodiments of this application is as follows:

[0051] By designing a mounting frame 3 supported by connecting rod 1 2 and connecting rod 2 4, the feeding frame can quickly and continuously feed the screen printing machine 8, and can ensure that the glass will not rub or collide with other structures during the feeding process, thus maintaining the original transparency of the glass.

[0052] Furthermore, since both connecting rod 2 and connecting rod 4 in this application are electrically controlled telescopic rods, the glass can be flipped quickly. For glass requiring double-sided processing, this application can significantly improve the efficiency of glass screen printing.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
