Description

Technical Field

[0001] This utility model relates to the field of screen printing device technology, specifically to a screen printing device with an automatic springback function. Background Technology

[0002] In numerous industrial sectors such as electronics, packaging, and textiles, screen printing technology, as an efficient and precise printing method, is widely used for printing patterns and text on various flat or curved workpieces. The core working components of a screen printing device include a printing platform and a screen printing plate. During the printing process, the screen printing plate needs to be in close contact with the surface of the workpiece placed on the printing platform. The ink is transferred to the workpiece surface through the mesh of the screen printing plate by a squeegee, completing the printing operation.

[0003] After printing, to achieve continuous production, the screen printing plate needs to be quickly separated from the workpiece and reset to its initial position for the next printing cycle. Currently, in screen printing equipment on the market, the reset of the screen printing plate is mostly done manually or by simple mechanical drive. Manual reset not only increases the labor intensity of operators, but also has low reset efficiency and difficulty in ensuring positional accuracy, seriously affecting printing quality and production efficiency; while traditional mechanical drive reset structures, such as direct cylinder pull or motor-driven linkage reset, often have the problem of large impact forces during the reset process.

[0004] When the screen printing plate rebounds rapidly under the action of the restoring force, if there is no effective buffering mechanism, the screen printing plate is prone to rigid collision with other parts of the device. On the one hand, this will cause the screen printing plate or related parts to wear and deform due to long-term impact, shortening the service life of the equipment. On the other hand, the violent collision will generate vibration, affecting the positioning accuracy of the screen printing plate, which will lead to quality problems such as deviation and blurring of the printed pattern.

[0005] Furthermore, some existing automatic springback structures are complex in design, inconvenient to adjust, and difficult to adapt to the printing needs of workpieces of different specifications, resulting in poor versatility. Therefore, how to develop an automatic springback structure for screen printing devices that is simple in structure, has stable springback, accurate positioning, and strong versatility has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] To address the shortcomings in the prior art, this utility model provides a screen printing device with an automatic springback function.

[0007] The technical solution adopted in this utility model is: a screen printing device with automatic springback function, including a printing platform and a screen printing plate, and further including:

[0008] The base is slidably mounted on the printing platform via a horizontal slide rail mechanism;

[0009] A horizontal position adjustment mechanism is fixedly mounted on the printing platform and connected to the base, used to drive the base to translate along the slide rail mechanism;

[0010] The column is fixed to the base;

[0011] The elastic reset element has its two ends connected to the upper part of the column and the non-hinged end of the screen printing plate, respectively, and provides a pulling force that causes the screen printing plate to spring back towards the column.

[0012] A buffer device, installed on the column, includes a mounting plate fixed on the column, a buffer rod that is vertically penetrating through a through hole in the mounting plate and is telescopically movable, a buffer block fixed on the top of the buffer rod, and a buffer spring sleeved on the outside of the buffer rod and pre-compressed between the mounting plate and the buffer block.

[0013] The screen printing plate is hinged to one side of the base via a hinge.

[0014] Furthermore, the horizontal position adjustment mechanism includes a fixed plate fixed on the printing platform and an adjusting screw threaded into the screw hole of the fixed plate, one end of which is rotatably connected to the base.

[0015] Furthermore, the elastic reset element is a tension spring or a strong rubber band.

[0016] Furthermore, the horizontal slide rail mechanism includes a linear slide rail arranged parallel to the printing platform and a matching slider, the slider being fixedly connected to the bottom of the base.

[0017] Furthermore, one side of the buffer block has an inclined surface that contacts the screen printing plate.

[0018] Furthermore, the end of the buffer rod away from the buffer block is an external thread section, and a tension adjustment nut is threaded onto the external thread section.

[0019] The beneficial effects of this utility model are:

[0020] 1. Achieve automatic springback and improve production efficiency: By setting up an elastic reset element, the screen printing plate can automatically spring back to the column after printing, without the need for manual intervention or complex mechanical drive control. This effectively reduces the labor intensity of operators, while significantly shortening the reset time, accelerating the printing cycle, and significantly improving overall production efficiency.

[0021] 2. Buffer protection, extending equipment life and ensuring printing quality: The design of the buffer device solves the problem of excessive impact force in traditional springback structures. When the screen printing plate rebounds, the buffer block contacts the screen printing plate first, and the buffer spring is compressed accordingly. The elastic deformation of the spring absorbs the impact energy, thereby slowing down and buffering the rebound process of the screen printing plate.

[0022] 3. Adjustable horizontal position to meet diverse needs: The horizontal position adjustment mechanism, in conjunction with the horizontal slide rail mechanism, can drive the base to smoothly move the column and screen printing plate along the printing platform. This allows for easy adjustment of the screen printing plate's horizontal position according to the printing requirements of workpieces of different specifications. This adjustment method is simple to operate and provides precise positioning, greatly enhancing the device's adaptability to workpieces of different sizes and shapes, and improving the equipment's versatility.

[0023] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0030] This invention provides a screen printing device with an automatic springback function.

[0031] In this embodiment, refer to Figure 1-2 The screen printing device with automatic springback function includes a printing platform 1 and a screen printing plate 2, and also includes:

[0032] The base 3 is slidably mounted on the printing platform via a horizontal slide rail mechanism;

[0033] A horizontal position adjustment mechanism is fixedly mounted on the printing platform and connected to the base, used to drive the base to translate along the slide rail mechanism;

[0034] Column 4 is fixed to the base;

[0035] The elastic reset element 5 has two ends connected to the upper part of the column and the non-hinged end of the screen printing plate, respectively, and provides a pulling force that causes the screen printing plate to spring back towards the column.

[0036] A buffer device, installed on the column, includes a mounting plate 6 fixed on the column, a buffer rod 8 that is vertically penetrating the mounting plate 6 and is telescopically movable, a buffer block 9 fixed on the top of the buffer rod 8, and a buffer spring 10 sleeved on the outside of the buffer rod and pre-compressed between the mounting plate and the buffer block.

[0037] The screen printing plate is hinged to one side of the base via a hinge 11.

[0038] In the above technical solution, the screen printing device is based on a printing platform and a screen printing plate. A horizontal slide rail mechanism allows the base to be slidably mounted on the printing platform. A horizontal position adjustment mechanism drives the base to move along the slide rail, adjusting the horizontal position of the screen printing plate. A column is fixed to the base, and the screen printing plate is hinged to one side of the base via a hinge, allowing it to rotate around the hinge point. An elastic reset element connects the upper part of the column and the non-hinged end of the screen printing plate, providing tension to cause the screen printing plate to spring back towards the column after printing. In the buffer device, a mounting plate is fixed to the side of the column, a buffer rod extends and retracts through a through-hole in the mounting plate, a buffer block is fixed to the top of the buffer rod, and a buffer spring is pre-compressed between the mounting plate and the buffer block. When the screen printing plate springs back, the buffer block contacts the screen printing plate and compresses the buffer spring, using the spring force to achieve deceleration and buffering.

[0039] It achieves automatic rebound of the screen printing plate without manual operation, improving production efficiency; the buffer device effectively reduces the impact force during rebound, avoids rigid collision of parts, extends equipment life, and at the same time ensures the positioning accuracy of the screen printing plate and ensures printing quality; the horizontal position is adjustable, which can adapt to the printing needs of workpieces of different specifications and enhances the versatility of the device.

[0040] Specifically, the horizontal position adjustment mechanism includes a fixed plate 12 fixed on the printing platform and an adjusting screw 13 threadedly engaged with the screw hole of the fixed plate 12. One end of the adjusting screw 13 is rotatably connected to the base.

[0041] In this embodiment, the horizontal position adjustment mechanism consists of a fixed plate and an adjusting screw. The fixed plate is fixed to the printing platform, and the adjusting screw is threaded into the screw hole of the fixed plate, with one end rotatably connected to the base. When the adjusting screw is rotated, due to the threaded engagement between the screw and the fixed plate, the screw will move axially, thereby causing the base to translate along the horizontal slide rail mechanism. By rotating the screw, the movement distance of the base can be precisely controlled, achieving accurate adjustment of the horizontal position of the screen printing plate and meeting printing operations with different precision requirements.

[0042] Specifically, the elastic reset element is a tension spring or a strong rubber band.

[0043] In this embodiment, both the tension spring and the strong rubber band have good elasticity and restoring ability, which can stably provide the tension to make the screen printing plate spring back, ensuring the reliability and consistency of the springback action.

[0044] Specifically, the horizontal slide rail mechanism includes a linear slide rail 14 parallel to the printing platform and a matching slider 15, wherein the slider 14 is fixedly connected to the bottom of the base.

[0045] In this embodiment, the horizontal slide rail mechanism consists of parallel linear slide rails and matching sliders, with the sliders fixedly connected to the bottom of the base. The linear slide rails provide precise guidance for the sliders. When the base moves under the drive of the horizontal position adjustment mechanism, the sliders slide smoothly along the linear slide rails, limiting the direction of movement of the base and ensuring that it can only translate along the axis of the slide rails.

[0046] Specifically, one side of the buffer block has an inclined surface 16 that contacts the screen printing plate.

[0047] In this embodiment, a slope is provided on one side of the buffer block to contact the screen printing plate. When the screen printing plate rebounds under the action of the elastic reset element, the screen printing plate will first contact the slope of the buffer block.

[0048] Specifically, the end of the buffer rod away from the buffer block is an external thread section 17, and a tension adjustment nut 18 is threaded onto the external thread section 17.

[0049] In this embodiment, the end of the buffer rod furthest from the buffer block is an externally threaded section, and a tension adjusting nut is threadedly connected to it. By rotating the tension adjusting nut, its position on the externally threaded section of the buffer rod can be changed, thereby adjusting the pre-compression of the buffer spring. When the tension adjusting nut moves towards the buffer block, the pre-compression of the buffer spring increases, and the initial elastic force is enhanced; conversely, the pre-compression decreases, and the initial elastic force is weakened.

[0050] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
