Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold connection technology, and in particular to a skin laser weakening and fixing device. Background Technology
[0002] The existing vacuum adsorption device for skin weakening mainly includes a base plate and a rotatable pressure plate that is fastened to the base plate. The base plate and pressure plate have corresponding weakening paths. Vacuum screens are arranged on both sides of the weakening paths on the base plate, and these screens are connected to the suction port of a vacuum pump. When the skin is placed on the fixture, it is adsorbed onto the base plate by the vacuum screens. The pressure plate is mounted on a horizontal rotating shaft, which is also mounted on the base plate. The shaft is connected to the output shaft of a tilting cylinder, which drives the shaft to open and close the pressure plate. The skin is positioned on the fixture by arranging positioning blocks around the base plate.
[0003] The main problems with existing adsorption devices are as follows:
[0004] 1. The existing device uses a combination of multiple vacuum screens to achieve vacuum adsorption. The surface of the vacuum screen is not flat when it meets the base plate of the fixture, which can easily damage the surface and cause the product to be scrapped. Each vacuum screen needs to be connected to an air pipe, and the excessive number of air pipes makes the design and manufacture of the fixture difficult.
[0005] 2. The existing device uses a single-piece pressure plate design, with a rotating shaft driven by a tilting cylinder to open and close the pressure plate. The integral pressure plate is large in size, and the torque is too large when the shaft rotates. The entire fixture shakes too much during the opening and closing of the pressure plate, which reduces the overall service life and stability of the fixture. The connecting parts between the fixture carrier and the fixture are also prone to damage.
[0006] 3. The existing equipment uses a perimeter positioning block to position the skin product. Since the skin itself is very soft, it cannot effectively support and position the product with the positioning block. Moreover, the skin outline needs to be modified multiple times due to the requirements of subsequent processes. After the skin outline is modified, the corresponding positioning blocks also need to be modified or remanufactured.
[0007] 4. Existing devices cannot monitor vacuum pressure, and the actual adsorption effect of the skin on the mold cannot be monitored. Utility Model Content
[0008] To address the aforementioned issues, this utility model provides a skin laser weakening and fixing device. By incorporating a vacuum adsorption fixing module on the tooling table, it achieves effective vacuum adsorption of the skin while resolving the problem of unevenness between the vacuum device and the base plate of the fixture, reducing the number of air pipes and simplifying the design and manufacturing difficulty of the fixture. Furthermore, by using a split-type flip-up pressure plate to press and fix the skin, it solves the problem of excessive shaking of the fixture during opening and closing, and addresses the issue of the skin and positioning block failing to provide effective support and positioning.

[0012] The tooling table is provided with an integral vacuum chamber at the bottom of the weakened area of the skin. The integral vacuum chamber is connected to a vacuum generator. Vacuum holes are provided on the tooling table in the area corresponding to the integral vacuum chamber.
[0013] The vacuum generator evacuates the integral vacuum chamber, and the skin can be adsorbed and fixed to the weakened area through the vacuum hole based on the air pressure.
[0014] In the above technical solution, preferably, the epidermal laser weakening fixation device further includes a sensor and a controller. The sensor is installed on the surface of the tooling table corresponding to the vacuum hole area. The sensor is connected to the controller, and the controller is connected to the vacuum generator to control the switching of the vacuum generator according to the detection data of the sensor.
[0015] In the above technical solution, preferably, the positioning pin is set on the tooling table and corresponds to the pre-cut round hole of the skin at a preset position, so that the skin is positioned by fitting the pre-cut round hole onto the positioning pin when laying the skin.
[0016] In the above technical solution, preferably, the vacuum holes are distributed on both sides of the tooling table corresponding to the integral vacuum cavity.
[0017] In the above technical solution, preferably, a pressure gauge is provided between the integral vacuum chamber and the connecting pipe of the vacuum generator.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: by building a vacuum adsorption fixing module on the tooling table, the surface can be effectively vacuum adsorbed, while solving the problem of unevenness between the vacuum device and the base plate of the fixture, reducing the number of air pipes and reducing the difficulty of fixture design and manufacturing; by using a split flip-type pressure plate to press and fix the surface, the problem of excessive shaking of the fixture during opening and closing is solved, and the problem of the surface and positioning block being unable to be effectively supported and positioned is solved.

[0026] The skin to be weakened is laid on the tooling table 1, and the tooling table 1 is equipped with positioning pins 2 for positioning the skin.
[0027] The split-type flip-over pressure plate 3 is installed separately at the preset position on the tooling table 1, and is driven to rotate relative to the tooling table 1 by the reciprocating cylinder 4, so that it can rotate onto the tooling table 1 to press the skin.
[0028] An integral vacuum chamber 6 is provided at the bottom of the weakened area of the surface corresponding to the tooling table 1. The integral vacuum chamber 6 is connected to the vacuum generator 8. A vacuum hole 5 is provided on the tooling table 1 in the area corresponding to the integral vacuum chamber 6.
[0029] The vacuum generator 8 evacuates the integral vacuum chamber 6, and the skin can be adsorbed and fixed to the weakened area through the vacuum hole 5 based on the action of air pressure.

[0031] Specifically, during implementation, the skin is positioned and laid on the tooling table 1 using positioning pins 2, and then pressed onto different positions of the skin using split-type flip-up pressure plates 3 to achieve tight fixation of the skin. By turning on the vacuum generator 8 to evacuate the integral vacuum chamber 6, the skin will be adsorbed under negative pressure at the vacuum hole 5, thereby achieving adsorption and fixation of the skin.

[0034] In the above embodiment, preferably, the positioning pin 2 is disposed on the tooling table 1 and corresponds to the pre-cut round hole of the skin at a preset position, so that the skin is positioned by fitting the pre-cut round hole onto the positioning pin 2 when laying the skin.
[0035] During implementation, the number and position of the positioning pins 2 and the pre-cut round holes are pre-set according to the specifications and type of the skin to be weakened, so that when laying the skin, the positioning pins 2 can be inserted into the pre-cut round holes on the skin to achieve the positioning of the skin.
[0036] In the above embodiments, preferably, the vacuum holes 5 are distributed on both sides of the integral vacuum cavity 6 on the tooling table 1 to increase the vacuum adsorption area and ensure the stability of the adsorption and fixation effect.
[0037] In the above embodiment, preferably, a pressure gauge 9 is provided between the integral vacuum chamber 6 and the connecting air pipe of the vacuum generator 8 to monitor the vacuum air pressure value and to reflect the adsorption capacity of the vacuum generator 8 on the skin.
