Description

Technical Field

[0001] This utility model relates to the field of release paper tearing technology, specifically a release paper tearing clamping device. Background Technology

[0002] Release paper, also known as release paper, anti-stick paper, or silicone paper, is a special functional paper with an anti-stick coating on its surface. It is widely used in packaging, electronic component manufacturing, and self-adhesive label production. Its core function is to prevent prepregs and self-adhesive substrates from sticking together during storage, transportation, and processing, and to protect the material surface from contamination.

[0003] Existing release paper tearing equipment and technical solutions generally have the following problems in practical applications: First, the clamping method is unreasonable, and the release paper is easily damaged or slips. Traditional equipment mostly adopts the structure of "mechanical claw single-point clamping" or "single negative pressure adsorption". When the mechanical claw clamps, the clamping force is concentrated at the contact point of the claw, which can easily cause the release paper to be subjected to excessive local force and tear. Although single negative pressure adsorption can disperse some pressure, when there are small wrinkles on the surface of the release paper or the edge of the substrate is uneven, the adsorption force is easily unbalanced, causing the release paper to slip during the tearing process and unable to complete stable separation. Moreover, the tearing force is concentrated at the adsorption edge, and there is still a risk of release paper damage. Secondly, the height adjustment relies on an additional drive, resulting in poor motion coordination: In order to adapt to release paper of different thicknesses or worktables of different heights, the existing equipment needs to adjust the height of the clamping mechanism through independent motors, cylinders and other drive components. This not only increases the complexity and cost of the equipment structure, but also requires additional sensors and control systems to coordinate the height adjustment and lateral tearing action. This can easily lead to action delays or asynchrony, which further affects the tearing effect. Therefore, improvements are needed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a release paper tearing and clamping device. Through the clamping structure formed by the combination of a multi-hole elastic suction nozzle and an annular airbag, and the automatic height adjustment mechanism of the wedge block and wedge plate, the height of the clamping module can be automatically adjusted to bring it close to the release paper and clamp and tear it off. This solves the problem that the current device has an unreasonable clamping method and is prone to damaging the release paper.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A release paper tearing and clamping device includes a transverse conveying module, a longitudinal conveying module, and a clamping module. The transverse conveying module includes a C-shaped frame and a limiting rod fixedly connected to the inner side of the C-shaped frame along its length. A transverse slider is slidably connected to the limiting rod. The longitudinal conveying module includes a guide rail fixedly connected to one side of the transverse slider and a longitudinal slider slidably connected to a track groove on one side of the guide rail. A wedge block is fixedly connected to one side of the longitudinal slider, and an L-shaped mounting plate is fixedly connected to the side of the wedge block away from the longitudinal slider by bolts. The clamping module is mounted on the bottom of the L-shaped mounting plate. The transverse conveying module and the longitudinal conveying module can respectively realize the X-axis and Y-axis movement of the clamping module, bringing it closer to the release paper and clamping and tearing it off.

[0009] Furthermore, a slanted groove is provided on one side of the wedge block, and a wedge plate is fixedly connected to one side of the C-shaped frame by a fixing rod. The wedge plate has a beveled surface that matches the slanted groove on the side near the wedge block. When the wedge block and the wedge plate come into contact, the longitudinal slider can be driven to slide downward in the track groove through the limiting relationship between the slanted groove and the beveled surface, so as to realize the automatic adjustment of the height of the L-shaped mounting plate and the clamping module, so that the clamping module is close to the release paper and is torn off and clamped.

[0010] Furthermore, a spring is provided in the track groove of the guide rail, and the two ends of the spring abut against the lower surface of the longitudinal slider and the inner bottom of the guide rail, respectively.

[0011] Furthermore, ear plates are fixedly connected to one side of the guide rail and one side of the transverse slider, and the two ear plates are fixed together by bolts.

[0012] Furthermore, a ball screw is rotatably connected to the inner side of the C-shaped frame, the transverse slider is threadedly connected to the ball screw through a screw hole provided on the inner side, and a motor for driving the ball screw to rotate is installed on one side of the C-shaped frame.

[0013] Furthermore, the clamping module includes a negative pressure pipe fixedly connected to the bottom of the L-shaped mounting plate, an air extraction cylinder connected to the lower end of the negative pressure pipe, and a multi-hole elastic suction nozzle connected to the lower end of the air extraction cylinder. The bottom of the multi-hole elastic suction nozzle is provided with an array of negative pressure holes. An annular airbag is fixedly connected to the outer wall of the multi-hole elastic suction nozzle. A first flexible hose is connected to one side of the annular airbag, and a second flexible hose is connected to one side of the negative pressure pipe. The first flexible hose is connected to an external inflation / deflation device, and the second flexible hose is connected to an external negative pressure device.

[0014] Furthermore, a fixing seat is fixedly connected to one side of the C-shaped frame, and the fixing seat is fixedly connected to an external device or a workbench.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a release paper tearing and clamping device, which has the following beneficial effects:

[0017] 1. This utility model, by opening an array of negative pressure holes at the bottom of the porous elastic nozzle, ensures that the negative pressure adsorption force is concentrated and does not penetrate the release paper, achieving a uniform distribution of adsorption force on the surface of the release paper. This transforms the traditional single-point / localized force application into "area-like dispersed force application," effectively preventing the release paper from tearing due to excessive localized force during the tearing process. Simultaneously, the porous elastic nozzle is made of silicone, possessing excellent elasticity and sealing properties, allowing it to conform to release paper surfaces of varying flatness. Even with minor wrinkles in the release paper, the nozzle's elastic deformation adapts, ensuring adsorption stability and preventing slippage. Furthermore, the annular airbag secures the substrate edge, eliminating wrinkle interference. The annular airbag surrounds the outside of the porous elastic nozzle; after inflation, it adheres tightly to the substrate edge, forming an "annular fixing ring." During tearing, the substrate edge is firmly fixed by the airbag, preventing displacement or wrinkling with the release paper's movement. This ensures the separation interface between the release paper and the substrate remains flat, avoiding incomplete separation or localized damage to the release paper caused by substrate wrinkles.

[0018] 2. Compared with the prior art which requires an independent motor and cylinder to drive height adjustment, this utility model utilizes the lateral movement power of the lateral transmission module. Through the contact and compression between the inclined groove of the wedge block and the inclined surface of the wedge plate, the lateral force is decomposed into a component force downward along the track groove, driving the longitudinal slider to automatically lower the clamping module and approach the release paper. After the release is completed, the spring in the track groove can automatically push the longitudinal slider to reset, driving the clamping module to rise again. The entire height adjustment process does not require additional drive components and control programs, which not only simplifies the equipment structure but also reduces the risk of failure caused by improper multi-drive coordination.

[0025] 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.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of this utility model proposes a release paper tearing and clamping device, including a transverse transmission module 1, a longitudinal transmission module 2, and a clamping module 3. The transverse transmission module 1 includes a C-shaped frame 101 and a limiting rod 106 fixedly connected to the inner side of the C-shaped frame 101 along the length direction of the C-shaped frame 101. A transverse slider 103 is slidably connected to the limiting rod 106. The longitudinal transmission module 2 includes a guide rail 201 fixedly connected to one side of the transverse slider 103 and a longitudinal slider 205 slidably connected to a track groove 202 on one side of the guide rail 201. A wedge block 206 is fixedly connected to one side of the longitudinal slider 205. An L-shaped mounting plate 208 is fixedly connected to the side of the wedge block 206 away from the longitudinal slider 205 by bolts. The clamping module 3 is installed at the bottom of the L-shaped mounting plate 208. The transverse transmission module 1 and the longitudinal transmission module 2 can respectively realize the X-axis and Y-axis movement of the clamping module 3, so that it approaches the release paper and clamps and tears it off.

[0028] It should be noted that the transverse transmission module 1, as the X-axis motion actuator, drives the ball screw 102 to rotate via the motor 108, converting the rotational motion into the linear motion of the transverse slider 103 along the limit rod 106. This, in turn, drives the longitudinal transmission module 2 and the clamping module 3 to achieve synchronous transverse displacement, completing the transverse action of "approaching the release paper" or "tearing off the release paper". The longitudinal transmission module 2, as the Y-axis motion actuator, uses the wedge block 206 and the inclined surface of the wedge plate 105 to convert part of the transverse power of the transverse transmission module 1 into the vertical linear motion of the longitudinal slider 205 along the track groove 202 of the guide rail 201, realizing the height adjustment of the clamping module 3 and ensuring its precise contact with the surface of the release paper.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a sloping groove 207 is provided on one side of the wedge block 206, and a wedge plate 105 is fixedly connected to one side of the C-shaped frame 101 by a fixing rod 104. The wedge plate 105 has a beveled surface that matches the sloping groove 207 on the side near the wedge block 206. When the wedge block 206 and the wedge plate 105 come into contact, the longitudinal slider 205 can be driven to slide downward at the track groove 202 through the limiting relationship between the sloping groove 207 and the beveled surface, so as to realize the automatic adjustment of the height of the L-shaped mounting plate 208 and the clamping module 3, so that the clamping module 3 is close to the release paper and is torn off and clamped.

[0030] It should be noted that when the transverse transmission module 1 drives the transverse slider 103 to move towards the release paper, the wedge block 206 of the longitudinal transmission module 2 moves synchronously with the transverse slider 103 until the inclined groove 207 of the wedge block 206 contacts the inclined surface of the wedge plate 105 of the transverse transmission module 1. Since the inclined angle of the inclined groove 207 and the inclined surface are matched, the longitudinal slider 205 can be driven to slide downward at the track groove 202 through the limiting relationship between the structures, thereby driving the L-shaped mounting plate 208 and the clamping module 3 to descend synchronously until the porous elastic suction nozzle 303 adheres to the surface of the release paper, completing the height adjustment. After the tearing action is completed, the transverse transmission module 1 drives the transverse slider 103 to move in the opposite direction, the wedge block 206 separates from the wedge plate 105, the elastic force of the spring 203 is released, pushing the longitudinal slider 205 to reset upward, and the clamping module 3 rises back to the initial height, preparing for the next tearing cycle.

[0031] like Figure 3 As shown, in some embodiments, a spring 203 is provided at the track groove 202 of the guide rail 201, and the two ends of the spring 203 abut against the lower surface of the longitudinal slider 205 and the inner bottom of the guide rail 201, respectively.

[0032] It should be noted that when the tearing is completed and the wedge block 206 separates from the wedge plate 105, the lateral thrust disappears, the elastic potential energy of the spring 203 is converted into kinetic energy, and the upward elastic force pushes the longitudinal slider 205 to move upward along the track groove 202 until the spring 203 returns to the pre-compressed state, and the longitudinal slider 205 returns to the initial position, realizing the automatic return of the clamping module 3.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, ear plates 204 are fixedly connected to one side of the guide rail 201 and one side of the transverse slider 103, and the two ear plates 204 are fixedly connected by bolts.

[0034] It should be noted that the detachable nature of the bolted connection allows the longitudinal transmission module 2 to be disassembled and maintained separately (such as replacing the spring 203 and the wedge block 206) without disassembling the entire transverse transmission module 1, making it convenient to use.

[0035] like Figure 2 As shown, in some embodiments, a ball screw 102 is rotatably connected to the inner side of the C-shaped frame 101, and a transverse slider 103 is threadedly connected to the ball screw 102 through a screw hole provided on the inner side. A motor 108 for driving the ball screw 102 to rotate is installed on one side of the C-shaped frame 101.

[0036] It should be noted that the motor 108 on one side of the C-shaped frame 101 starts after receiving the control signal, and the output shaft drives the ball screw 102 to rotate inside the C-shaped frame 101. The ball screw 102 is rotatably connected to the C-shaped frame 101 through a bearing to ensure no radial offset during rotation. The inner side of the transverse slider 103 is provided with an internal threaded hole that matches the ball screw 102. When the ball screw 102 rotates, the meshing between the threads will generate a "driving force along the screw axis". Since the transverse slider 103 is also sleeved on the limiting rod 106, the limiting rod 106 restricts the rotational freedom of the transverse slider 103, causing it to move linearly along the length direction (X-axis) of the limiting rod 106. By controlling the rotation direction (forward / reverse) of the motor 108, the transverse slider 103 can be moved "closer to the release paper" or "away from the release paper", thereby controlling the start and reset of the tearing action.

[0037] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the clamping module 3 includes a negative pressure tube 301 fixedly connected to the bottom of the L-shaped mounting plate 208, an air pump 302 connected to the lower end of the negative pressure tube 301, and a porous elastic suction nozzle 303 connected to the lower end of the air pump 302. The bottom of the porous elastic suction nozzle 303 is provided with arrayed negative pressure holes 307. Furthermore, an annular airbag 304 is fixedly connected to the outer wall of the porous elastic suction nozzle 303. A first hose 305 is connected to one side of the annular airbag 304, and a second hose 306 is connected to one side of the negative pressure tube 301. The first hose 305 is connected to an external inflation / deflation device, and the second hose 306 is connected to an external negative pressure device.

[0038] It should be noted that an external negative pressure device (such as a vacuum pump) draws air into the negative pressure pipe 301 through the second flexible hose 306, creating a negative pressure environment inside the negative pressure pipe 301, the air extraction cylinder 302, and the porous elastic suction nozzle 303. Because the porous elastic suction nozzle 303 has an array of negative pressure holes 307 at its bottom, the external atmospheric pressure exerts pressure on the release paper, causing it to adhere firmly to the nozzle surface. Simultaneously, the nozzle is made of silicone, which has good elasticity and can deform with the minute wrinkles on the release paper surface, ensuring close contact between the negative pressure holes 307 and the release paper, and preventing adhesion failure due to poor sealing. Simultaneously, an external inflation device (such as a pneumatic pump) inflates the annular airbag 304 through the first hose 305. After the airbag expands, it adheres tightly to the edge of the substrate (non-release paper area) below the release paper, forming an "annular pressure ring". This pressure ring exerts a continuous clamping force on the substrate, fixing the substrate position and preventing the substrate from wrinkling as it moves with the release paper during the tearing process. After tearing, the external deflation device releases the gas in the airbag through the first hose 305, causing the airbag to contract and release the clamping force on the substrate. The synergy of the dual clamping structure not only fixes the release paper through negative pressure adsorption but also fixes the substrate through the airbag, reducing the release paper damage rate.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, a fixing seat 107 is fixedly connected to one side of the C-shaped frame 101. The fixing seat 107 is fixedly connected to an external device or a workbench, so as to realize the installation and fixation of the device on the external device or workbench.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
