Description

Technical Field

[0001] This utility model belongs to the field of panel processing technology, and specifically relates to a cutting device. Background Technology

[0002] Applying a protective film to the panel is an essential step in the panel manufacturing process, especially for LCD screens and touch screens, which are easily scratched or damaged during production, transportation, and use. Applying a protective film effectively prevents these physical damages, maintaining the screen's appearance and functionality. During the panel application process, the protective film needs to be cut according to the panel size. Currently, after panel application, the protective film is primarily cut manually, which is not only inefficient but also increases labor costs for operators.

[0003] Therefore, it is necessary to provide a cutting device to address the aforementioned technical problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device that can solve the problem of low efficiency in manual cutting of protective film.

[0006] To achieve the above objectives, a specific embodiment of the present invention provides a cutting device, including: a frame, a sliding mechanism, and a cutting shear assembly.

[0007] A transmission assembly is mounted on the frame. The sliding mechanism is mounted on the frame and includes: a pair of mounting seats, a pair of first sliding rods, a slider, and a transmission mechanism. The pair of mounting seats are respectively mounted on the two side walls of the frame. The pair of first sliding rods are fixed between the pair of mounting seats. The transmission mechanism is mounted between the pair of mounting seats and is used to drive the slider to slide on the first sliding rods.

[0008] The cutting scissors assembly is mounted on the bottom of the slider. The assembly includes a shaft seat, cutting tools, a cutting track, and a reset component. The shaft seat is fixed to the bottom of the slider, and a rotating shaft is rotatably mounted on the shaft seat. A pair of connecting rods are fixed to both ends of the rotating shaft. The cutting tools are mounted on the ends of the connecting rods away from the rotating shaft. The cutting track is fixed to the frame and located directly below the cutting tools. A groove adapted to the cutting tools is carved into the cutting track. The reset component is installed between the slider and the rotating shaft and is used to reset the cutting tools.

[0009] In one embodiment of this utility model, the transmission mechanism includes: a pair of fixed seats, a pair of belt gears, and a belt. The pair of fixed seats are respectively fixed to both sides of a pair of mounting seats. The pair of belt gears rotate on the pair of fixed seats. The belt is mounted on the pair of belt gears, and one side of the belt is connected to the slider. The belt is driven to rotate by the belt gears, and the belt controls the slider to slide on the first sliding rod.

[0010] In one embodiment of this utility model, a slide rail is fixed between a pair of mounting seats, and the belt slides on the upper and lower ends of the slide rail respectively. By embedding the belt into the upper and lower ends of the slide rail and sliding therein, shaking during belt drive is prevented, thereby ensuring that the connection between the slider and the belt does not become loose.

[0011] In one embodiment of this utility model, the slider has a groove adapted to the slide rail, and a fixing plate is fixed to the groove by bolts. The groove is for the slide rail to be disposed therein, and the sidewall of the groove is also slidably disposed with the slide rail. The fixing plate is used to connect with both the slider and the belt, so that when the belt rotates, it drives the slider to slide on the first slide rod.

[0012] In one embodiment of this utility model, the fixing plate is provided with multiple connecting grooves, and multiple connecting blocks are fixed on the belt, with each connecting block respectively engaged in one of the connecting grooves. By having the connecting blocks engaged in the connecting grooves, the belt rotation causes the slider to slide on the first sliding rod.

[0013] In one embodiment of this utility model, a drive shaft is connected to one of the belt gears. The drive shaft drives the drive device to rotate, thereby causing the belt gear to rotate and thus the belt gear to rotate.

[0014] In one embodiment of this utility model, a pair of first pulleys are installed on both sides of the cutting tool, and the first pulleys slide on the cutting track. The pair of first pulleys sliding on the cutting track are used to prevent the blade tip of the cutting tool from contacting the cutting track when cutting the protective film on the cutting track, thus preventing wear of the blade tip.

[0015] In one embodiment of this utility model, the cutting track has downwardly inclined sliding areas at both ends, and mounting heads are fixed at both ends of the cutting track. The cutting track is fixed to the frame by the mounting heads at both ends. Since the cutting blades are in a vertical state when they are at both ends, when cutting, after the first pulley contacts the sliding areas at both ends of the cutting track, the connecting rod tilts in the opposite direction of the cutting direction. At the same time, the reset spring force of the reset component presses the first pulley tightly against the upper surface of the cutting track, thereby pressing the protective film for cutting. When the first pulley slides to the sliding area at the other end of the cutting track, the reset spring force of the reset component makes the connecting rod return to a vertical state.

[0016] In one embodiment of this utility model, the reset assembly includes: a pair of second slide rods, a push plate, and two pairs of control arms. The pair of second slide rods are both fixed to the bottom of the slider and are located on both sides of the shaft seat. The push plate slides on the pair of second slide rods, and springs are installed on each pair of second slide rods between the push plate and the slider. The two pairs of control arms are respectively inclined and fixed to both sides of the rotating shaft, and the angles between the two pairs of control arms and the vertical horizontal plane are the same. Simultaneously, the ends of the two pairs of control arms away from the rotating shaft are attached to the bottom of the push plate.

[0017] When the cutting tool cuts, the connecting rod tilts. At this time, a pair of springs press the push plate downward. The push plate pushes the control arm away from the rotating shaft, so that the first pulley presses the protective film on the cutting track. When cutting, after the first pulley slides out of the sliding area at one end of the cutting track, the push plate pushes the control arm away from the rotating shaft, so that the connecting rod is in a vertical state.

[0018] In one embodiment of this utility model, a second pulley is fixed to the end of each pair of control arms away from the rotating shaft. The second pulley is used to reduce the sliding friction between the end of the control arm away from the rotating shaft and the push plate.

[0019] Compared with existing technologies, this utility model, through its structural design, can effectively improve the cutting effect of protective film and greatly reduce the labor costs for operators. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0029] like Figures 1 to 5 As shown, a cutting device in one embodiment of the present invention includes: a frame 1, a sliding mechanism 2, and a cutting shear assembly 3.

[0030] like Figures 1 to 5 As shown, a transmission assembly 101 is mounted on the frame 1. A sliding mechanism 2 is mounted on the frame 1 and includes: a pair of mounting seats 208, a pair of first sliding rods 201, a slider 202, and a transmission mechanism. The pair of mounting seats 208 are respectively mounted on the two side walls of the frame 1. The pair of first sliding rods 201 are fixed between the pair of mounting seats 208. The transmission mechanism is mounted between the pair of mounting seats 208 and is used to drive the slider 202 to slide on the first sliding rods 201.

[0031] like Figures 1 to 5 As shown, the cutting scissors assembly 3 is installed at the bottom of the slider 202. The cutting scissors assembly 3 includes: a shaft seat 301, a cutting tool 304, a cutting track 306, and a reset assembly 309. The shaft seat 301 is fixed to the bottom of the slider 202, and a rotating shaft 302 is rotatably mounted on the shaft seat 301. A pair of connecting rods 303 are fixed to both ends of the rotating shaft 302. The cutting tool 304 is installed at the end of the pair of connecting rods 303 away from the rotating shaft 302. The cutting track 306 is fixed to the frame 1 and is located directly below the cutting tool 304. A groove 307 adapted to the cutting tool 304 is carved on the cutting track 306. The reset assembly 309 is installed between the slider 202 and the rotating shaft 302 and is used to reset the cutting tool 304.

[0032] In use, the protective film to be cut is placed on the transmission assembly 101 and conveyed to the bottom of the sliding mechanism 2 for cutting. During cutting, the sliding mechanism 2 drives the slider 202 to slide on the first slide rod 201 via the transmission mechanism, causing the slider 202 to drive the cutting scissors assembly 3 to cut the protective film at the bottom. During cutting, the slider 202 drives the cutting scissors 304 to move via the shaft seat 301. After the cutting scissors 304 moves to the cutting track 306 and contacts it, the connecting rod 303 changes from its original vertical state to tilting in the opposite direction of cutting. Simultaneously, the reset spring force of the reset assembly 309 presses the cutting scissors 304 firmly onto the cutting track 306. This cuts the protective film on the cutting track 306. After cutting is complete, the cutting scissors 304 slides out from the other end of the cutting track 306. The resetting spring force of the resetting component 309 once again brings the connecting rod 303 into a vertical state, thus preparing it to be tilted and pressed onto the protective film again during the next cut.

[0033] like Figures 4 to 5 As shown, the transmission mechanism includes: a pair of fixed seats 204, a pair of belt gears 205, and a belt 207. The pair of fixed seats 204 are respectively fixed to both sides of a pair of mounting seats 208. The pair of belt gears 205 rotate on the pair of fixed seats 204. The belt 207 is mounted on the pair of belt gears 205, and one side of it is connected to the slider 202. The belt 207 is driven to rotate by the belt gears 205, and the belt 207 controls the slider 202 to slide on the first slide rod 201.

[0034] like Figures 4 to 5As shown, a slide rail 203 is fixed between a pair of mounting bases 208, and a belt 207 slides on the upper and lower ends of the slide rail 203 respectively. By embedding the belt 207 into the upper and lower ends of the slide rail 203 and sliding therein, it is used to prevent the belt 207 from shaking during transmission, thereby ensuring that the connection between the slider 202 and the belt 207 does not become loose. The slider 202 has a groove 209 that is adapted to the slide rail 203, and a fixing plate 210 is fixed to the groove 209 by bolts. The groove 209 is used for the slide rail 203 to be located therein, and the side wall of the groove 209 is also slidably set with the slide rail 203. The fixing plate 210 is used to connect with both the slider 202 and the belt 207, so that when the belt 207 rotates, it drives the slider 202 to slide on the first slide rod 201.

[0035] like Figures 4 to 5 As shown, the fixed plate 210 has multiple connecting slots 212, and the belt 207 has multiple connecting blocks 211 fixed on it. The connecting blocks 211 are respectively engaged in the connecting slots 212. Because the connecting blocks 211 are engaged in the connecting slots 212, the belt 207 rotates, causing the slider 202 to slide on the first slide rod 201. A drive shaft 206 is connected to one of the belt gears 205. The drive shaft 206 drives the drive device to rotate, which in turn drives the belt gear 205 to rotate, thus causing the belt 207 to rotate.

[0036] like Figures 1 to 5 As shown, a pair of first pulleys 305 are installed on both sides of the cutting tool 304, and the first pulleys 305 slide on the cutting track 306. The pair of first pulleys 305 slide on the cutting track 306 to prevent the cutting tool 304 from contacting the cutting track 306 when cutting the protective film on the cutting track 306, thus preventing wear of the cutting tip.

[0037] like Figures 4 to 5 As shown, the cutting track 306 has downwardly sloping sliding areas at both ends, and mounting heads 308 are fixed at both ends of the cutting track 306. The cutting track 306 is fixed to the frame 1 by the mounting heads 308 at both ends. Since the cutting blades 304 are in a vertical state when they are located at both ends, when cutting, after the first pulley 305 contacts the sliding areas at both ends of the cutting track 306, the connecting rod 303 tilts in the opposite direction of the cutting direction. At the same time, the reset spring force of the reset component 309 presses the first pulley 305 against the upper surface of the cutting track 306, thereby pressing the protective film for cutting. When the first pulley 305 slides to the sliding area at the other end of the cutting track 306, the reset spring force of the reset component 309 makes the connecting rod 303 return to a vertical state.

[0038] like Figures 4 to 5 As shown, the reset assembly 309 includes: a pair of second slide rods 312, a push plate 313, and two pairs of control arms 310. The pair of second slide rods 312 are both fixed to the bottom of the slider 202 and are located on both sides of the bearing 301. The push plate 313 slides on the pair of second slide rods 312, and springs 314 are installed on each of the second slide rods 312 between the push plate 313 and the slider 202. The two pairs of control arms 310 are respectively inclined and fixed to both sides of the rotating shaft 302, and the angles between the two pairs of control arms 310 and the vertical horizontal plane are the same. Simultaneously, the ends of the two pairs of control arms 310 away from the rotating shaft 302 are attached to the bottom of the push plate 313.

[0039] When the cutting tool 304 cuts, the connecting rod 303 tilts. At this time, a pair of springs 314 press the push plate 313 downward. The push plate 313 pushes the control arm 310 away from the end of the rotating shaft 302, so that the first pulley 305 presses the protective film on the cutting track 306. When cutting, after the first pulley 305 slides out of the sliding area at one end of the cutting track 306, the push plate 313 pushes the control arm 310 away from the end of the rotating shaft 302, so that the connecting rod 303 is in a vertical state.

[0040] like Figure 5 As shown, each of the two pairs of control arms 310 has a second pulley 311 fixed at the end away from the rotating shaft 302. The second pulley 311 is used to reduce the sliding friction between the end of the control arm 310 away from the rotating shaft 302 and the push plate 313.

[0041] Working principle: When using this device, an external drive unit is connected to the drive shaft 206 to drive it to reciprocate. The protective film to be cut is then placed on the transmission assembly 101. It is then conveyed to the bottom of the sliding mechanism 2 for cutting via the transmission assembly 101. During cutting, the sliding mechanism 2 drives the belt gear 205 to rotate via the drive shaft 206. The belt gear 205 drives the belt 207 to rotate, causing the belt 207 to drive the slider 202 to slide on the first slide rod 201. The slider 202 then drives the cutting shear assembly 3 to cut the protective film at the bottom.

[0042] During cutting, the slider 202 drives the cutting tool 304 to move via the bearing 301. When the cutting tool 304 moves to the lower section of the cutting track 306, the first pulley 305 contacts the cutting track 306. The connecting rod 303 then changes from its original vertical state to an inclined state in the opposite direction to the cutting direction. At this time, the connecting rod 303 drives the two pairs of control arms 310 to rotate via the rotating shaft 302. This causes the second pulley 311 on one pair of control arms 310 to push the push plate 313 upwards, compressing the spring 314. The rebound force of the spring 314 also acts on the push plate 313, causing the push plate 313 to push the second pulley 311 downwards. The control arm 310 then provides a reverse rotational force to the rotating shaft 302, causing the rotating shaft 302 to press the first pulley 305 onto the cutting track 306 via the connecting rod 303, thereby pressing the protective film and then cutting it.

[0043] Once the cutting is complete, the first pulley 305 slides out from the other end of the cutting track 306, and the rebound force of the spring 314 causes the rotating shaft 302 to rotate again, driving the connecting rod 303 to rotate to a vertical position, thus preparing for the next cutting to be tilted and pressed onto the protective film again.

[0044] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description.
