Description

Technical Field

[0001] This utility model belongs to the field of metal surface treatment technology, and more specifically, it relates to a low-adhesion film positioning device for metal film application. Background Technology

[0002] Metal lamination is a key process for improving the surface protection, decorative effect, and functional characteristics of metal parts. It is widely used in the production of many products such as electronic components, automotive parts, and home appliance casings. However, as downstream industries continue to increase their requirements for product precision, quality stability, and production efficiency, traditional metal lamination technology has gradually revealed many shortcomings that make it difficult to meet the needs of modern production, becoming a major bottleneck restricting the high-quality development of the industry.

[0003] Understanding of existing applications for low-tack film positioning in metal lamination: 1. Traditional positioning relies on manual or simple mechanical positioning, which cannot accurately fix irregular metal parts with a semi-circular structure on the right side. It is easy to cause displacement, movement or angular deviation, resulting in misalignment, bubbles, wrinkles or missed application of the film.

[0004] 2. Currently, film application and cutting are separate processes. Low-adhesion film is prone to displacement during process transitions. Furthermore, the processes of material loading and positioning, film application, and waste film disposal rely heavily on manual labor, resulting in low efficiency and incompatibility with high-speed production lines. Manual operation may also contaminate or damage metal parts and low-adhesion film, reducing quality stability. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a low-adhesion film positioning device for metal lamination. This device solves the problems of existing film positioning methods that rely on manual labor or simple mechanical positioning, which cannot accurately fix irregularly shaped metal parts with a semi-circular structure on the right side. These methods are prone to offset, movement, or angular deviation, resulting in misalignment, bubbles, wrinkles, or missed areas in the film application. Currently, film application and cutting are separate processes, and the low-adhesion film is prone to displacement during process transitions. Furthermore, the processes of material loading and positioning, film laying, and waste film disposal rely heavily on manual labor, resulting in low efficiency and incompatibility with high-speed production lines. Manual operation may also contaminate or damage the metal parts and the low-adhesion film, reducing quality stability.

[0006] The technical solution adopted in this utility model is as follows: A low-adhesion film positioning device for metal film application includes a device base; the top front end of the device base is fixedly connected to the middle of the bottom of the positioning platform; a motor A is arranged at the lower left side of the positioning platform, and the rotating shaft of the motor A is equipped with a gripper; a limit rod is arranged at the front left side of the top of the positioning platform; a motor B is arranged at the lower right side of the positioning platform, and the rotating shaft of the motor B is fixedly connected to a C-shaped component; a metal component is placed at the top of the positioning platform; the right side of the metal component has a semi-circular structure design, and the right side of the metal component is located inside the C-shaped component; the limit rod is engaged in a slot at the front left side of the metal component; and the gripper is abutted at the rear left side of the metal component.

[0007] According to one embodiment of the present invention, a lifting frame is fixedly installed at the top rear position of the device base. The lifting frame is located directly behind the positioning platform. A motor C is fixedly installed at the top middle position of the lifting frame, and the rotating shaft of the motor C is located inside the lifting frame.

[0008] According to one embodiment of the present invention, a lifting component is slidably connected to the front end of the lifting frame, and a threaded hole is provided at the rear top of the lifting component, with the shaft of the motor C located inside the threaded hole of the lifting component.

[0009] According to one embodiment of the present invention, a cylinder is fixedly installed at the top front position of the lifting component, and a stamping and cutting frame is slidably connected at the bottom front end position of the lifting component. The telescopic rod of the cylinder is fixedly connected to the top middle position of the stamping and cutting frame. A part pressing groove is provided at the bottom of the stamping and cutting frame, and the part pressing groove of the stamping and cutting frame is located directly above the metal part.

[0010] According to one embodiment of the present invention, the lower front position of the lifting frame is fixedly connected to the middle rear end position of the positioning frame, and a winding machine is respectively arranged on the left and right sides of the positioning frame, and a motor D is arranged behind each winding machine.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. A multi-directional positioning system is formed by a limiting rod, grippers, and C-shaped component on the positioning platform. The limiting rod engages with the front left side of the metal part through a slot, limiting its lateral and longitudinal position; motor A drives the grippers to clamp from the rear left side, and motor B drives the C-shaped component to engage with the semi-circular structure on the right side of the metal part. The three components work together to effectively fix irregularly shaped metal parts, eliminate positioning deviations, ensure accurate film application, reduce problems such as bubbles and missed applications from the source, and improve product consistency.

[0012] 2. Motor C adjusts the height of the lifting component through threaded transmission, and the cylinder drives the stamping and cutting frame to move downward. The bottom part pressing groove can simultaneously achieve low-adhesion film pressing to the metal part and precise edge cutting without the need for transfer processes. This design reduces process changeover time, avoids low-adhesion film displacement in intermediate links, reduces material waste, and achieves a high degree of matching between the cutting edge and the metal part contour. No additional processing of residual edges is required afterward, and production efficiency is increased by more than 30%.

[0013] 3. The winding machines on both sides of the positioning frame are driven by independent motors D. The unwinding and winding speeds can be adjusted synchronously to ensure consistency, and the tension during the unwinding and waste film winding processes of the low-adhesion film can be precisely controlled. After 1-2 trial runs, it can be ensured that the low-adhesion film is flat and without deviation, avoiding loose stacking or stretching deformation. When applying the film, the low-adhesion film adheres tightly to the surface of the metal parts, effectively reducing warping and wrinkles. During mass production, the product yield can be stabilized at over 98%.

[0014] 4. The device can automatically complete the entire process of "metal part positioning, low-adhesion film laying, film cutting, waste film winding, and resetting and picking up parts". Only manual feeding and picking are required. The automated operation not only reduces the single cycle time to half of the traditional process, but also avoids the impact of manual oil stains and uneven force on the product. At the same time, it reduces the labor intensity of operators, adapts to the needs of high-speed mass production, and significantly improves the overall capacity and quality stability of the production line.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example

[0025] As attached Figure 1 To be continued Figure 6 As shown: This utility model provides a low-adhesion film positioning device for metal film application, including a device base 1; the top front end of the device base 1 is fixedly connected to the middle of the bottom of the positioning platform 101; a motor A102 is provided at the lower left side of the positioning platform 101, and a gripper 103 is provided on the rotating shaft of the motor A102; a limit rod 106 is provided at the front left side of the top of the positioning platform 101; a motor B104 is provided at the lower right side of the positioning platform 101, and a C-shaped part 105 is fixedly connected to the rotating shaft of the motor B104; a metal part 4 is placed at the top of the positioning platform 101; the right side of the metal part 4 has a semi-circular structure design, and the right side of the metal part 4 is located inside the C-shaped part 105; the front left side of the metal part 4 is engaged with the limit rod 106; and the gripper 103 is attached to the rear left side of the metal part 4.

[0026] The device base 1 has a lifting frame 2 fixedly installed at the top rear position. The lifting frame 2 is located directly behind the positioning platform 101. The lifting frame 2 has a motor C201 fixedly installed at the top middle position, and the rotating shaft of the motor C201 is located inside the lifting frame 2.

[0027] The lifting frame 2 has a lifting component 202 slidably connected to its front end. The lifting component 202 has a threaded hole at the rear top position, and the shaft of the motor C201 is located in the threaded hole of the lifting component 202.

[0028] Among them, a cylinder 203 is fixedly installed at the top front position of the lifting component 202, and a stamping and cutting frame 204 is slidably connected at the bottom front position of the lifting component 202. The telescopic rod of the cylinder 203 is fixedly connected to the top middle position of the stamping and cutting frame 204. A part pressing groove is provided at the bottom of the stamping and cutting frame 204, and the part pressing groove of the stamping and cutting frame 204 is located directly above the metal part 4.

[0029] The lower front of the lifting frame 2 is fixedly connected to the middle of the rear end of the positioning frame 3. A winding machine 301 is set on the left and right sides of the positioning frame 3, and a motor D302 is set at the rear of each winding machine 301.

[0030] When using: Start motors A102 and B104 to position the gripper 103 and C-shaped part 105 in a horizontally open position. The operator places the metal part 4 on top of the positioning table 101, aligning the left slot of the metal part 4 with and engaging the limiting rod 106, and inserting the right semi-circular structure into the groove of the C-shaped part 105. Control motor A102 to drive the gripper 103 to close until the gripper 103 is in contact with the rear left surface of the metal part 4, with a clamping force of 50-80N to prevent deformation of the metal part 4. At the same time, motor B104 drives the C-shaped part 105 to rotate slightly, so that the inner wall of the C-shaped part 105 is completely in contact with the right semi-circular structure of the metal part 4, thus completing the fixation of the metal part 4. Install the roll of low-adhesion film onto the reel of the left winding machine 301. Manually pull the free end of the low-adhesion film through the middle position between the stamping and cutting frame 204 and the metal part 4, ensuring that the low-adhesion film covers the area to be filmed on the metal part 4 above the positioning table 101. Start the motors D302 on both sides, adjust the speed to the synchronous speed, and run 1-2 revolutions to ensure that the low-adhesion film is discharged smoothly without deviation and has uniform tension.

[0031] Start motor C201. The shaft of motor C201 drives the lifting component 202 to slide downward along the lifting frame 2 through threaded transmission, thereby adjusting the height of the stamping and cutting frame 204. This ensures that when the cylinder component 203 is in the extended state, the top position of the metal part 4 is located in the part pressing groove of the stamping and cutting frame 204. Start the cylinder component 203 to extend, and the stamping and cutting frame 204 presses the low-adhesion film onto the top of the metal part 4. At the same time, the edge of the part pressing groove of the stamping and cutting frame 204 edge-cuts the low-adhesion film, completing the film application step.

[0032] After the cutting is completed, the cylinder 203 drives the stamping and cutting frame 204 to return to the initial position; at the same time, the right-side winding machine 301 starts and winds up the cut waste film at a uniform speed. The winding speed is consistent with the output speed of the left-side winding machine 301 until the waste film is completely removed from the positioning table 101 area, completing a single film application-cutting-winding cycle.

[0033] When the metal part 4 is removed, start motors A102 and B104 to open the gripper 103 and reset the C-shaped part 105. The operator then removes the metal part 4 that has been coated with film and checks the quality of the film coating on the metal part 4.

[0034] Although this application has been described with reference to the foregoing embodiments, those skilled in the art will understand that various changes can be made without departing from the spirit and scope of this application as defined by the appended claims. While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
