Description

Technical Field

[0001] The utility model relates to the technical field of mask preparation, in particular to a plastic welding mask preparation device. Background Art

[0002] During the plastic laser welding process, a mask is needed to block the laser beam so that it can only illuminate specific areas. This mask is usually composed of a high-quality quartz glass substrate and a light-shielding material (such as chromium). It is used to precisely control the laser irradiation path during plastic welding to ensure the accuracy and quality of welding. Therefore, plastic welding masks play a key role in laser welding, and their demand is also increasing.

[0003] The preparation of plastic welding masks generally requires specialized equipment. In particular, in order to achieve the desired appearance, the mask needs to be cut into the required shape. During the cutting process, the mask sheet is relatively light and requires a special clamping and fixing mechanism to stabilize it. The required clamping mechanism has high operating costs and generally still requires manual support for operation, which is less convenient. Secondly, during the preparation, the vibration generated by the mechanical operation can easily affect the cutting effect. Directly using a mechanical clamping and stabilization method can also easily damage the mask.

[0004] Therefore, we propose a plastic welding mask preparation device to solve the above problems. Utility Model Content

[0031] Example 1:

[0032] Combine Figure 1-Figure 3 As shown, the utility model provides a plastic welding mask preparation device,

[0033] Specifically, it includes a mounting bracket 1, a workbench 2, an electric telescopic mechanism 5, a mask 13 and a regulating mechanism 23. Conveying mechanisms 3 are symmetrically installed on both sides of the top of the workbench 2. The two sets of continuously operating conveying mechanisms 3 can continuously convey and output the mask 13, mainly through the continuous pushing of the mask 13, and the overall conveying of the cut mask 13 is more convenient. A mounting slot 10 is provided in the middle of the workbench 2, and a supporting protective frame plate 9 is provided at the top of the mounting slot 10. A heat insulation plate 14 is installed at the bottom of the supporting protective frame plate 9. When the heat insulation plate 10 is connected and installed with the supporting protective frame plate 9 and the support plate 12, its heat insulation effect also prevents the heat caused by the laser cutting gun 6 during cutting from damaging the components. The heat insulation plate 1 4 is installed with a support plate 12, and the left and right sides of the supporting protective frame plate 9 are symmetrically provided with push-pull clamping blocks 16 on both sides of the top of the mounting slot 10. The bottom end of the push-pull clamping block 16, the left and right sides of the support plate 12 and the inner bottom end of the mounting slot 10 are symmetrically installed with rotating connecting blocks 21. The second connecting rod 18 is rotatably installed between the bottom end of the push-pull clamping block 16 and the left and right sides of the support plate 12 through the rotating connecting block 21. The first connecting rod 17 is rotatably installed between the bottom end of the push-pull clamping block 16 and the inner bottom end of the mounting slot 10 through the rotating connecting block 21. The side ends of the push-pull clamping block 16 are close to the left and right sides of the supporting protective frame plate 9 and are connected with silicone extrusion pads 19. The silicone material of the silicone extrusion pad 19 is not only elastic, but also has a high high temperature resistance effect, which improves In order to improve durability, the bottom end of the regulating mechanism 23 is connected to the mounting plate 4 through transmission. The front and rear end bottoms of the mounting plate 4 are symmetrically connected with extrusion column rods 8. The bottom ends of the extrusion column rods 8 can be close to the top of the supporting and protective frame plate 9. The laser cutting gun 6 and the monitoring camera 7 are installed on the left and right sides of the bottom end of the mounting plate 4 respectively. The monitoring camera 7 is mainly used for real-time monitoring to facilitate remote control of the operator. The mask 13 is located just above the supporting and protective frame plate 9. A movable slide rail 22 is provided at the inner top of the mounting bracket 1. The movable slide rail 22 is mainly used to facilitate the electric telescopic mechanism 5 to move horizontally through the driving mechanism at the top, and cooperate with the transmission of the regulating mechanism 23 to drive the mounting plate 4 so that the laser cutting gun 6 can be adjusted in multiple positions for better cutting. The conveying mechanism 3 is close to On both sides of the top of the mounting slot 10, the top of the electric telescopic mechanism 5 is slidably engaged with the inside of the movable slide rail 22, and the bottom output end of the electric telescopic mechanism 5 is transmission-connected with the top extension end of the regulating mechanism 23. With the use of the above-mentioned components, after the conveying mechanism 3 conveys the mask 13 to the top of the supporting and protective frame plate 9, the up and down movement of the mounting plate 4 drives the movement of the extrusion column 8, and squeezes the front and rear top ends of the supporting and protective frame plate 9, so that the insulation plate 14 squeezes the support plate 12, driving the second connecting rod 18 and the first connecting rod 17 to fold and rotate, so that the push-pull clamp 16 rotates and tilts to squeeze and clamp the silicone extrusion pad 19 on the left and right sides of the mask 13, which is convenient for cutting, reduces the overall operating cost and manual operation of clamping, and improves the convenience of use.

[0034] Example 2:

[0035] Combine Figure 2 and Figure 3 As shown, based on the first embodiment,

[0036] Specifically, a plurality of mounting struts 15 are evenly installed in the middle of the inner bottom end of the mounting slot 10. The mounting struts 15 are mainly used to facilitate the installation of the spring 11 and to cooperate with the sliding slot 20 to enable the movement of the support plate 12. The outer sides of the plurality of mounting struts 15 are all sleeved with springs 11, and the bottom end of the support plate 12 is evenly provided with a plurality of sliding slots 20. The sliding slots 20 are mainly used to limit and stabilize the up and down movement of the support plate 12. The top side surfaces of the plurality of mounting struts 15 are respectively slidably connected to the inner sides of the plurality of sliding slots 20. The use of the above-mentioned components and the components in Example 1, when the support plate 12 is squeezed and moved downward, the spring 11 is squeezed by the sliding of the plurality of mounting struts 15 through the sliding slot 20. The elastic action of the silicone extrusion pad 19 connected to one end of the spring 11 and the push-pull clamp 16 slows down the overall vibration force and reduces damage to the mask 13.

[0037] Combine Figure 1 and Figure 2 As shown, in the above embodiment,

[0038] Specifically, the mounting bracket 1 is installed on the top of the workbench 2. The mounting bracket 1 is an L-shaped frame structure, and the bottom end is connected to the top end of the rear side of the workbench 2. The bottom of the extended end surface at the top front end is provided with a movable slide rail 22 and an electric telescopic mechanism 5 and other components. A support base 24 is installed at the bottom end of the workbench 2. The support base 24 is mainly used to support and stabilize the workbench 2 and the mounting bracket 1 as a whole.

[0039] The working principle and use process of the present invention are as follows: First, when in use, the operator mainly controls the remote control through the monitoring of the monitoring camera 7. First, the mask 13 is conveyed by starting the operation of the conveying mechanism 3. After passing the top of the installation slot 10 and being located at the top of the supporting and protective frame plate 9, the operation of the electric telescopic mechanism 5 is controlled to make the installation plate 4 drive the movement of the extrusion column 8 up and down, so that it squeezes the front and rear tops of the supporting and protective frame plate 9, and makes the insulation board 14 squeeze the support plate 12, and drives the second connecting rod 18 and the first connecting rod 17 to rotate through the folding rotation of the rotating connecting block 21, so that the push-pull clamping block 16 rotates and tilts and makes the silicon The rubber extrusion pad 19 squeezes and clamps the left and right sides of the mask 13, and the convenient operating control mechanism 23 adjusts the laser cutting gun 6 at the bottom end of the mounting plate 4 to cut, which not only reduces the operating cost of clamping, but also reduces manual operation and improves ease of use. Secondly, during use, the operation of the above-mentioned components causes the support plate 12 to be squeezed and moved downward, and the spring 11 on its outside is squeezed by sliding along the multiple mounting struts 15 through the sliding groove 20. The elastic action of the spring 11 and the elastic clamping method of the silicone extrusion pad 19 connected to one end of the push-pull clamp 16 slow down the vibration force of the supporting protective frame plate 9 and reduce damage to the mask 13.
