Description

Technical Field

[0001] This utility model relates to the field of PCB printing auxiliary tools, and in particular to a screen printing plate transfer and temporary storage device. Background Technology

[0002] Screen printing, as an important printing technology, is widely used in many fields such as electronics, textiles, advertising, and packaging. In the screen printing process, the frequent transfer and temporary storage of the screen printing plate is a key step in the production process.

[0003] Traditional methods of transferring and temporarily storing screen printing plates often rely on simple manual operations and rudimentary tools. For example, operators typically handle the printing plates directly by hand, which is not only inefficient but also prone to damaging the plates, such as scratching or bending them. This affects the accuracy and lifespan of the printing plates, ultimately leading to decreased print quality and increased production costs.

[0004] With the expansion of production scale and the continuous improvement of printing quality requirements, traditional methods of transferring and temporarily storing printing plates can no longer meet the needs of modern industrial production. Furthermore, in some highly automated screen printing production lines, if the transfer and temporary storage of printing plates cannot be effectively coordinated with automated equipment, it can become a bottleneck in the entire production process, reducing production efficiency and equipment utilization. Therefore, there is an urgent need for a device that can efficiently, safely, and stably transfer and temporarily store screen printing plates to solve the aforementioned problems in existing technologies and improve the overall efficiency and product quality of screen printing production.

[0005] Chinese utility model patent CN 214140477 U discloses a screen printing plate transfer and temporary storage device, comprising: a lower support assembly including a pair of base plates, each base plate having several support rods extending upwards, and guide members at the upper ends of the support rods on the same side; a temporary storage assembly located on the guide members for temporary storage of the screen printing plate; and a feeding assembly consisting of a lifting mechanism located on the temporary storage assembly, with feeding mechanisms at both ends of the lifting mechanism and a pushing mechanism at the upper end of the feeding mechanism. The lifting mechanism drives the feeding mechanism to perform lifting and lowering movements, the feeding mechanism is used to place the screen printing plate during feeding, and the pushing mechanism is used to push the screen printing plate within the feeding mechanism towards the temporary storage assembly. This utility model facilitates the temporary storage and transfer of completed screen printing plates, enables automated temporary storage of screen printing plates, effectively prevents scratches on the screen printing plates, improves the automation of screen printing plate production, and has strong practicality.

[0006] The above-mentioned device has at least the following technical defects:

[0007] 1. The above-mentioned device cannot clamp screen printing plates of different thicknesses. When transferring the screen, the shaking of the machine body will cause damage to the screen printing plate, resulting in a decrease in the quality of the screen.

[0008] 2. The above-mentioned device achieves temporary storage and transfer of screen printing plates through a complex structure. The structure is too complex, the use and manufacturing costs are too high, and it is not universally applicable. Utility Model Content

Detailed Implementation

[0027] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1-6 As shown, this utility model provides a screen printing plate transfer and temporary storage device, including a vehicle body 1, four universal wheels 9 evenly distributed at the bottom end of the vehicle body 1, a push handle 3 installed on one side of the outer surface of the vehicle body 1, an adjustment mechanism 4 installed on the vehicle body 1; a clamping frame 2, which is composed of several independent clamping plates, the gap between the clamping plates is used to place the screen printing plate, and the size of the gap between the clamping plates is adjusted by the adjustment mechanism 4; several rollers 12, which are rotatably installed on the bottom surface of the vehicle body 1; and a baffle 5, which is movably installed on the side of the vehicle body 1 away from the push handle 3.

[0029] The baffle 5 is rotatably connected to the bottom of the left and right sides of the vehicle body 1. The outer surfaces of the left and right sides of the vehicle body 1 are respectively equipped with fixing plates 8. The outer surfaces of the left and right sides of the baffle 5 are respectively fixed with protruding plates 7. The outer surfaces of the protruding plates 7 and the fixing plates 8 are respectively provided with through holes. The inner walls of the through holes are equipped with detachable bolts 6.

[0030] The clamping plate includes a first clamping rod 201 that contacts the outer surface of the roller 12 and is perpendicular to the center line of the roller 12. A U-shaped second clamping rod 202 is provided on the top of the first clamping rod 201. The first clamping rod 201 and the second clamping rod 202 are fixedly connected by a plurality of third clamping rods 203. A first guide block 204 is fixedly connected to the side of the first clamping rod 201 near the push handle 3 and the bottom surface of the side away from the push handle 3, respectively. A second guide block 206 is fixedly connected to both ends of the second clamping rod 202, respectively. A guide rod 205 is fixedly connected to the outer surface of the third clamping rod 203 near the push handle 3.

[0031] The inner walls at the bottom of the vehicle body 1 are provided with first guide grooves 10 on both sides, and the inner walls at the top of the vehicle body 1 are provided with second guide grooves 13 on both sides. The first guide block 204 and the second guide block 206 are slidably connected to the inner walls of the first guide groove 10 and the second guide groove 13, respectively.

[0032] An adjustable plate 303 that can move up and down is installed on the side of the vehicle body 1 near the push handle 3. Connecting blocks 305 are fixed to the upper and lower ends of the outer surface of the adjustable plate 303. A threaded rod 302 is rotatably connected to the side of the vehicle body 1 near the push handle 3. The threaded rod 302 is threadedly connected to the two connecting blocks 305. Several adjusting grooves 304 that are adapted to the guide rod 205 are opened on the outer surface of the adjustable plate 303. The symmetry lines of the several adjusting grooves 304 under the plane view are all diverging outward along the central axis of the threaded rod. A crank handle 301 is fixed to the top of the threaded rod 302.

[0033] Limiting plates are installed at both ends of the vehicle body 1 near the push handle 3. Guide plates 306 are fixed to the left and right ends of the adjusting plate 303. The guide plates 306 are adapted to the third guide groove 14 opened on the limiting plate.

[0034] The working principle of this device is as follows: By shaking the handle 301, the threaded rod 302 is rotated. Since the threaded rod 302 is threadedly connected to the connecting block 305 on the adjusting plate 303, when the threaded rod 302 rotates, the adjusting plate 303 will move up and down along the third guide groove 14 on the limiting plate. The outer surface of the adjusting plate 303 has several adjusting grooves 304 that are adapted to the guide rod 205. The symmetry lines of the several adjusting grooves 304 under the plane view are all diverging outward along the central axis of the threaded rod. When the adjusting plate 303 moves up and down, the guide rod 205 slides in the adjusting groove 304, driving the first clamping rod 201 and the second clamping rod 202 of the clamping plate to move left and right. The first guide block 204 and the second guide block 206 slide in the first guide groove 10 and the second guide groove 13 of the vehicle body 1, respectively, to ensure the stability of the clamping plate when it moves left and right, thereby realizing the adjustment of the gap between the clamping plates to adapt to screen printing plates of different sizes.

[0035] The baffle 5 is rotatably connected to the bottom of the left and right sides of the vehicle body 1. When it is necessary to place or remove the screen printing plate, the bolt 6 can be removed from the through holes of the protruding plate 7 and the fixing plate 8, and the baffle 5 can be rotated to open. Especially when placing the screen printing plate, one end of the baffle 5 can be in contact with the ground. At this time, the baffle 5 and the ground form a slope to facilitate the user to place the screen printing plate. After the screen printing plate is placed, the bolt 6 can be installed to fix the position of the baffle 5 through the fixing plate 8 and the protruding plate 7. The baffle 5 can prevent the screen printing plate from slipping off the rear end of the vehicle body 1 when it is transferred, which further improves the stability of the device.

[0036] When the screen printing plate is placed between the clamping plates and on the roller 12, the roller 12 can rotate during the movement of the device, reducing the friction between the screen printing plate and the bottom surface of the vehicle body 1, thus protecting the bottom surface of the screen printing plate and further increasing the practicality and functionality of the device.

[0037] In this device, the gap between the clamping plates of the clamping frame 2 can be adjusted by the adjustment mechanism 4, which can accommodate screen printing plates of various sizes, improve the versatility of the device, and enable it to be used in different screen printing scenarios. This reduces the trouble of having to replace different temporary storage devices due to different printing plate sizes and expands the applicability of this device.

[0038] In this device, casters 9 and a push handle 3 are installed at the bottom, making it easy for operators to push the device to the required position. During movement, the roller 12 can effectively reduce the friction between the screen printing plate and the bottom surface of the vehicle body 1, preventing the screen printing plate from being damaged due to friction, and also making the pushing device more effortless.

[0039] In this device, the baffle 5 is designed to prevent the screen printing plate from accidentally sliding out of the vehicle body during movement or temporary storage, thus providing good protection for the screen printing plate. Moreover, the baffle 5 is connected by bolts 6, which makes it easy to open and close, and will not cause operational difficulties when placing or taking out the printing plate. Furthermore, the baffle 5 can play an auxiliary role when placing the screen printing plate.

[0040] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
