Description
Technical Field
[0001] This application relates to the field of positioning fixtures, and more specifically, to a positioning fixture for printing adhesive on components. Background Technology
[0002] Component printing adhesive is a process used in the field of electronic manufacturing. Its core lies in achieving precise application of adhesive through positioning fixtures to meet the needs of component fixing, sealing, or conductivity. This technology significantly improves production efficiency and product consistency by optimizing the shortcomings of traditional dispensing processes, and is especially suitable for the assembly of miniaturized, high-density electronic components.
[0003] During the processing, positioning fixtures are used to position the components to be processed. In the printing stage, steel mesh or flexible templates are used, along with squeegee pressure, to make the adhesive evenly pass through the template opening and accurately transfer it to the designated area of the component. In the curing stage, heat curing, UV curing, or room temperature curing methods are selected according to the characteristics of the adhesive to finally form an adhesive layer that meets the design requirements.
[0004] Current positioning fixtures typically use mechanical clamps for rigid clamping and positioning, which can easily cause circuit boards to be deformed or even damaged, thus affecting the processing quality and reducing the practicality of the device. Utility Model Content
[0005] To overcome the above shortcomings, this application provides a positioning fixture for printing adhesive on electronic components, which aims to improve the problem that positioning fixtures usually rely on mechanical clamps for rigid clamping and positioning, making the circuit board easily deformed or even damaged, thus affecting the processing quality and reducing the practicality of the device.
[0006] This application provides a positioning fixture for printing adhesive on electronic components, including a frame structure and a positioning structure. The frame structure includes a mounting plate, support rods, and a positioning plate. The support rods are fixedly connected to the four corners of the bottom of the positioning plate, and the support rods are fixedly connected to the mounting plate. The positioning structure includes positioning posts, vacuum holes, a fixing frame, a connecting pipe, and a vacuum generator body. Several positioning posts are fixedly connected around the positioning plate, and the positioning posts are fixedly connected to the mounting plate. Several vacuum holes are formed through the positioning plate. The fixing frame is fixedly connected to one side of the positioning plate, and the vacuum holes communicate with the fixing frame. The two ends of the connecting pipe communicate with the fixing frame and the vacuum generator body, respectively. The vacuum generator body is mounted on one side of the mounting plate.
[0007] In one specific implementation, the outer ring of the positioning post is slidably connected to a positioning assembly.

The two ends of the spring are fixedly connected to the slider and the inner wall of the connecting frame, respectively. The pull block is fixedly connected to the two sliders.

[0008] In the above implementation process, the circuit board can be easily clamped by setting up a rotating block, two connecting frames, a sliding rod, a spring, a slider, a pull block, and a pressure block, thus improving the fixing effect.
[0009] In one specific implementation, a groove is provided on one side of the connecting frame, and the slider is slidably connected to the groove.
[0010] In the above implementation process, the slider and the groove are slidably connected, which makes it easy to limit the movement of the slider.
[0011] In one specific implementation, a rubber pad is fixedly connected to one side of the pressure block.
[0012] In the above implementation process, by fixing a rubber pad to one side of the pressure block, the friction between the pressure block and the circuit board can be increased, preventing slippage and displacement, while protecting the circuit board surface from scratches by the pressure block.
[0013] In one specific implementation, a limiting block is provided on one side of the rotating block, and a limiting groove is formed on the outer ring of the positioning column, with the limiting block and the limiting groove being slidably connected.
[0014] In the above implementation process, the movement of the rotating block can be conveniently limited by the sliding connection between the limiting block and the limiting groove.
[0015] In one specific implementation, a plurality of clearance grooves are provided on one side of the positioning plate.
[0016] In the above implementation process, by opening several clearance slots on one side of the positioning plate, it is possible to provide a convenient space for the protruding components on the circuit board, avoid interference between the positioning plate and the components, and expand the compatibility of the fixture with the circuit board.
[0017] In one specific implementation, the mounting plate has a plurality of mounting holes extending through it.
[0018] In the above implementation process, by providing several mounting holes through the mounting plate, the fixture can be easily and quickly connected to other equipment.
[0019] Compared with the prior art, the beneficial effects of this application are as follows: by setting up the positioning post, vacuum hole, fixing frame, connecting tube and vacuum generator body, the circuit board can be easily vacuum adsorbed. At the same time, by setting up the positioning component, the circuit board can be further pressed, improving the fixing effect. Meanwhile, the elastic fixing avoids deformation and damage to the circuit board during the positioning process. Attached Figure Description

Detailed Implementation
[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0027] Please see Figure 1 This application provides a positioning fixture for printing adhesive on electronic components, including a frame structure 10 and a positioning structure 20.
[0028] Please see Figure 1 and Figure 2The frame structure 10 includes a mounting plate 110, a support rod 120 and a positioning plate 130. The support rod 120 is fixedly connected to the four corners of the bottom of the positioning plate 130, and the support rod 120 is fixedly connected to the mounting plate 110.
[0029] In a specific configuration, a number of clearance slots 140 are provided on one side of the positioning plate 130. By providing a number of clearance slots 140 on one side of the positioning plate 130, space can be conveniently provided for protruding components on the circuit board, avoiding interference between the positioning plate 130 and the components, and expanding the compatibility of the fixture with the circuit board.
[0030] In a specific configuration, the mounting plate 110 has several mounting holes through it, which allows for easy and quick connection of the fixture to other equipment.
[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The positioning structure 20 includes positioning posts 210, vacuum holes 220, fixing frames 230, connecting pipes 240, and a vacuum generator body 250. Several positioning posts 210 are fixedly connected around the positioning plate 130. The positioning posts 210 are fixedly connected to the mounting plate 110. Several vacuum holes 220 are opened through the positioning plate 130. The fixing frame 230 is fixedly connected to one side of the positioning plate 130. The vacuum holes 220 are connected to the fixing frame 230. The two ends of the connecting pipe 240 are connected to the fixing frame 230 and the vacuum generator body 250, respectively. The vacuum generator body 250 is installed on one side of the mounting plate 110.
[0032] In a specific configuration, a positioning component 260 is slidably connected to the outer ring of the positioning post 210. The positioning component 260 includes a rotating block 261, two connecting frames 262, a sliding rod 263, a spring 264, a slider 265, a pull block 266, and a pressure block 267. The rotating block 261 is slidably connected to the positioning post 210, the two connecting frames 262 are fixedly connected to both sides of the rotating block 261, the sliding rod 263 is slidably connected to the connecting frames 262, and the slider 265 is fixedly connected to the sliding rod 263. The slider 265 is slidably connected to the connecting frame 262. The two ends of the spring 264 are fixedly connected to the inner walls of the slider 265 and the connecting frame 262, respectively. The pull block 266 is fixedly connected to the two sliders 265. The pressure block 267 is fixedly connected to one end of the slide rod 263. The combination of the rotating block 261, the two connecting frames 262, the slide rod 263, the spring 264, the slider 265, the pull block 266, and the pressure block 267 facilitates the clamping of the circuit board and improves the fixing effect.
[0033] In a specific configuration, a groove is provided on one side of the connecting frame 262, and the slider 265 is slidably connected to the groove. The sliding connection between the slider 265 and the groove allows for convenient limitation of the movement of the slider 265.
[0034] In the specific setup, a rubber pad 270 is fixedly connected to one side of the pressure block 267. By fixing the rubber pad 270 to one side of the pressure block 267, the friction between the pressure block 267 and the circuit board can be increased, preventing slippage and displacement, and protecting the circuit board surface from scratches by the pressure block 267.
[0035] In a specific configuration, a limit block 280 is provided on one side of the rotating block 261, and a limit groove is provided on the outer ring of the positioning post 210. The limit block 280 is slidably connected to the limit groove. The slidable connection between the limit block 280 and the limit groove can conveniently limit the movement of the rotating block 261.
[0036] The working principle of this positioning fixture for printing adhesive on electronic components is as follows: When using the positioning fixture for printing adhesive on electronic components, the circuit board is placed on the surface of the positioning plate 130, and the position is calibrated by the positioning post 210 for easy positioning. Then, the vacuum generator body 250 is activated to evacuate the vacuum hole 220 through the connecting pipe 240 and the fixing frame 230, so that the circuit board is adsorbed and fixed. This allows for easy vacuum adsorption of the circuit board. By manually pulling the pull block 266, the slider 265 slides along the slide groove of the connecting frame 262 and compresses the spring 264, so that the horizontal position of the pressure block 267 is higher than the circuit board. At this time, the limiting block 280 slides and engages with the limiting groove of the positioning post 210, so that the pressure block 267 slides above the circuit board. The spring 264 resets and drives the sliding rod 263 and the pressure block 267 to move, so that the rubber pad 270 is attached to one side of the circuit board. At this time, the hand is released to facilitate further pressing of the circuit board, which improves the fixing effect. At the same time, the elastic fixing avoids deformation and damage to the circuit board during the positioning process.
[0037] It should be noted that the specific model and specifications of the vacuum generator body 250 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0038] The power supply and principle of the vacuum generator body 250 are clear to those skilled in the art and will not be described in detail here.
[0039] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
