Description

Technical Field

[0001] This utility model relates to the field of automated precision screen stretching machine technology, specifically to an automated precision screen stretching machine. Background Technology

[0002] An automated precision screen stretching machine is a piece of equipment used in the screen printing industry. It is primarily used to stretch and fix the screen to a screen printing frame with high precision. Employing advanced control systems and drive technology, it can precisely adjust the tension of the screen, ensuring uniform stretching and thus improving the quality and accuracy of the printed products. It is widely used in high-precision screen printing processes in industries such as solar photovoltaics, circuit boards, LCD touch screens, electronics, and glass printing.

[0003] Existing automated precision wire mesh stretching machines consist of a frame and wire mesh clamping devices. During operation, the wire mesh clamps the perimeter of the wire mesh, and then a displacement mechanism extends the clamps outward to tighten the wire mesh. During the stretching process, the control system precisely adjusts the tension of each clamp to ensure uniform wire mesh tension.

[0004] However, the automated precision screen stretching machine lacks a limiting structure on the table for placing the printing frame. During the process of applying screen adhesive to the surface where the screen is straightened and bonded to the printing frame, excessive operator movement can easily cause the printing frame to shift, hindering the adhesive application. Furthermore, due to variations in screen material and their varying extensibility under tension, if the printing frame shifts, the screen will not properly cover its surface, affecting the stretching process. Utility Model Content

[0005] To address the aforementioned issues, an automated precision screen stretching machine is provided. A clamping assembly can limit the printing frame, preventing it from shifting. A telescopic rod and elastic positioning module enable clamping of printing frames of different sizes. A push cylinder and moving platform can push the printing frame upwards, unfolding the top of the screen, further improving the unfolding effect of the automated precision screen stretching machine.

[0006] To address the existing technical problems, this utility model provides an automated precision screen pulling machine, including a machine body and a screen pulling device arranged around the machine body that can move laterally in four directions along the same horizontal plane. The top of the screen pulling device is provided with several clamps distributed along the length and width directions of the machine body.

[0007] It also includes two sets of horizontally movable clamping components arranged in four directions along the same horizontal plane. The two sets of clamping components are a transverse clamping component arranged along the length direction of the machine body and a longitudinal clamping component arranged along the width direction of the machine body. Rolling steel balls are provided at both the transverse clamping component and the longitudinal clamping component.

[0008] A guide groove is provided on the body, and the clamping assembly slides along the extension direction of the guide groove.

[0009] Preferably, a rotating frame is provided in the middle of the machine body, the outwardly extending parts of the rotating frame are connecting parts, and the middle of the rotating frame extends downward to form a shaft. Four adjusting arms are provided between the connecting parts and the clamping assembly, and a telescopic rod extending along the guide groove is provided at the transverse clamping assembly.

[0010] Preferably, each of the four adjusting arms is provided with a pin at both ends, and the four adjusting arms are rotatably connected to the connecting part, the longitudinal clamping assembly and the telescopic rod respectively through the pins.

[0011] Preferably, the machine body is provided with a drive mechanism that drives the rotating frame to rotate and moves the clamping assembly by adjusting the arm.

[0012] Preferably, the clamping assembly includes a clamping plate located at the top of the machine body and a sliding seat located inside the guide groove that can slide along the extension direction of the guide groove. An adjustment block is provided at the bottom of the clamping plate extending vertically downward, and an adjustment groove is provided in the sliding seat to cooperate with the adjustment block.

[0013] Preferably, the adjusting block is provided with an elastic positioning module, the sliding seat is provided with a positioning groove that works in conjunction with the elastic positioning module, and the back of the adjusting block is provided with a mounting plate that works in conjunction with the elastic positioning module.

[0014] Preferably, the telescopic rod is connected to the sliding seat at the transverse clamping assembly, and the rolling steel ball is embedded in the clamping plate.

[0015] Preferably, a moving platform is provided on the top of the machine body and a pushing cylinder is installed inside the machine body. A connecting plate is provided at the bottom of the moving platform, and the top of the pushing cylinder and the driving mechanism are both connected to the connecting plate.

[0016] Preferably, the guide groove is formed on the mobile platform and the rotating frame and adjusting arm are both located within the mobile platform.

[0017] The advantages of this utility model compared to the prior art are:

[0018] 1. By using clamping components set along the guide groove, the printing frame placed on the top of the machine body can be limited to prevent the printing frame from shifting, thus making the automatic precision screen forming machine achieve better screen covering effect.

[0019] 2. By setting a telescopic rod, the clamping range of the lateral clamping component can be adjusted in one step, which is suitable for covering printing frames of different lengths and widths.

[0020] 3. The clamping plate and sliding seat at the clamping assembly can be adjusted in height by adjusting the elastic positioning module, which is suitable for printing frames of different thicknesses;

[0021] 4. By setting up a moving platform that can be pushed vertically by a cylinder, the printing frame at the machine body can be moved upward, which in turn allows the printing frame to push the top of the screen upward and unfold, further improving the unfolding effect of the automated precision screen stretching machine.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] See Figure 1 and Figure 2 As shown, an automated precision screen pulling machine includes a machine body 1 and a screen pulling device 2 arranged around the machine body 1, which can move laterally in four directions along the same horizontal plane. The top of the screen pulling device 2 is provided with several clamps 2a distributed along the length and width directions of the machine body 1.

[0033] It should be noted that during use, the printing frame is placed on the upper side of the machine body 1, and the screen is clamped to the top of the screen stretching device 2 using the clamps 2a. Finally, the screen is stretched outwards using the screen stretching device 2 so that it flatly covers the top of the printing frame. The screen stretching device 2 includes a movable frame for mounting the clamps 2a and a linear module.

[0034] See Figure 1 As shown, it also includes two sets of horizontally movable clamping components 3 arranged in four directions along the same horizontal plane. The two sets of clamping components 3 are a transverse clamping component arranged along the length direction of the body 1 and a longitudinal clamping component arranged along the width direction of the body 1. Rolling steel balls 3a are provided at both the transverse clamping component and the longitudinal clamping component.

[0035] A guide groove is provided at the body 1, and the clamping assembly 3 slides along the extension direction of the guide groove.

[0036] It should be noted that after the printing frame is placed on the upper side of the machine body 1, the clamping component 3 clamps the printing frame, limiting it to the middle of the machine body 1 and preventing it from shifting, thus improving the coating effect of the automated precision screen forming machine. The rolling steel ball 3a reduces friction in the clamping component 3 during the adjustment of the printing frame's position, facilitating better adjustment of the printing frame's position.

[0037] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a rotating frame 4 is provided in the middle of the body 1. The parts of the rotating frame 4 that extend outwards are connecting parts, and the middle of the rotating frame 4 extends downwards to form a shaft. Four adjusting arms 4a are provided between the connecting parts and the clamping assembly 3. A telescopic rod 3b extending along the guide groove is provided at the transverse clamping assembly.

[0038] It should be noted that by rotating the rotating frame 4, the adjusting arm 4a can pull the clamping assembly 3 along the guide groove to the side where the printing frame is located, thereby clamping the printing frame.

[0039] See Figure 5 As shown, each of the four adjusting arms 4a has a pin at both ends, and the four adjusting arms 4a are rotatably connected to the connecting part, the longitudinal clamping assembly and the telescopic rod 3b respectively through the pins.

[0040] The machine body 1 is equipped with a drive mechanism that drives the rotating frame 4 to rotate and pulls the clamping assembly 3 to move via the adjusting arm 4a.

[0041] It should be noted that the drive mechanism includes a drive motor, a reduction gear, and a coupling for connecting the output end to the shaft of the rotating frame 4. During operation, the drive motor drives the rotating frame 4 to rotate via the reduction gear and the shaft connected by the coupling, which in turn drives the clamping assembly 3 to clamp the printing frame via the adjusting arm 4a. When the length-to-width ratio of the printing frame changes, the clamping ratio of the transverse and longitudinal clamping assemblies can be adjusted by adjusting the length of the telescopic rod 3b.

[0042] See Figure 2-8 As shown, the clamping assembly 3 includes a clamping plate 3c located at the top of the body 1 and a sliding seat 3d located inside the guide groove and slidable along the extension direction of the guide groove. An adjustment block 3c1 is provided vertically downward at the bottom of the clamping plate 3c, and an adjustment groove is provided in the sliding seat 3d to cooperate with the adjustment block 3c1.

[0043] The adjusting block 3c1 is provided with an elastic positioning module 3c2, and the sliding seat 3d is also provided with a positioning groove that works in conjunction with the elastic positioning module 3c2. The back of the adjusting block 3c1 is provided with a mounting plate that works in conjunction with the elastic positioning module 3c2.

[0044] It should be noted that the elastic positioning module 3c2 consists of a pull handle penetrating the mounting plate, a pull rod hinged to the pull handle, a positioning block hinged to the pull rod, and a connecting spring that pushes the pull rod to its reset position. When the height of the clamping plate 3c needs to be adjusted, pull the pull handle. This pulls the pull rod, folding and compressing the connecting spring, until the pull rod pulls the positioning block away from the positioning groove. At this point, the clamping plate 3c can be moved upwards along the adjustment groove to adjust its clamping height.

[0045] See Figure 7 As shown, the telescopic rod 3b is connected to the sliding seat 3d at the transverse clamping assembly, and the rolling steel ball 3a is embedded in the clamping plate 3c.

[0046] See Figure 2 and Figure 3As shown, a mobile platform 1a is provided on the top of the machine body 1 and a push cylinder 1b is installed inside the machine body 1. A connecting plate 1a1 is provided at the bottom of the mobile platform 1a. The top of the push cylinder 1b and the drive mechanism are both connected to the connecting plate 1a1.

[0047] It should be noted that by pushing cylinder 1b, the printing frame on top of the moving platform 1a can be moved upward, which in turn allows the printing frame to further push the top mesh upward and unfold, thereby further improving the unfolding effect of the automated precision screen forming machine on the mesh.

[0048] See Figure 1 , Figure 3 and Figure 4 As shown, the guide groove is formed on the mobile platform 1a, and the rotating frame 4 and the adjusting arm 4a are both located within the mobile platform 1a.

[0049] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
