Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and in particular to protective fixtures. Background Technology

[0002] In the assembly of electronic devices, adhesive bonding is often involved. When using adhesive bonding, adhesive or cleaning agents can easily enter the electronic device through the functional openings, thus affecting the yield of the electronic device.

[0003] For example, when applying adhesive to pre-assembled half-films, it is necessary to protect holes such as button holes and microphone holes to prevent alcohol and glue used during application or polishing from entering them. However, before applying adhesive or polishing, the protection of these holes typically involves manually attaching foam or Mylar sheets to the holes. Manual attachment may result in misalignment, incomplete protection, low efficiency, and increases the cost of personnel and auxiliary materials such as foam and Mylar sheets.

[0004] Therefore, how to improve the protection effect of holes in electronic devices during processes such as adhesive application and polishing, improve process efficiency, and reduce protection costs has become a hot research topic in this field. Utility Model Content

[0038] In the assembly of electronic devices, adhesive bonding is often involved. When using adhesive bonding, adhesive or cleaning agents can easily enter the electronic device through the functional openings, thus affecting the yield of the electronic device.

[0039] For example, the screen and mid-frame are fixed together with double-sided tape and hot melt adhesive. During screen assembly, the hot melt adhesive is pressed out to fill the gap between the screen and the mid-frame, causing adhesive overflow. Therefore, a glue-removing machine is needed to wipe away most of the overflow, followed by polishing the adhesive lines with a lint-free cloth and a polishing cloth dampened with a small amount of alcohol to achieve the desired appearance. However, manually applying alcohol during this process can easily cause the mixture of glue and alcohol to seep into the product's functional holes and interior, leading to issues such as button malfunctions, audio problems, impacting after-sales service (FFR), and affecting brand reputation.

[0040] This disclosure provides a protective device. Figure 1 This is a schematic cross-sectional view of a protective fixture according to an exemplary embodiment of this disclosure. Figure 2 This is a schematic diagram of a partial mating structure between a protective fixture and a product component in an exemplary embodiment of this disclosure. Figure 3 This is a schematic diagram of a partial mating structure between a protective fixture and a product component in another exemplary embodiment of this disclosure, as shown below. Figures 1-3 As shown, Figure 1 The dashed arrow indicates the direction of movement of the protective component 12. The protective fixture 1 includes a carrier 11 and at least one protective component 12. The carrier 11 includes a product positioning mounting part 112 and at least one movable mounting part 111. The product positioning mounting part 112 is used to position and assemble the product component 2. The protective component 12 includes a base 121 and a sealing structure 122 disposed on the base 121. The movable mounting part 111 includes a first position and a second position. The base 121 and the movable mounting part 111 are movably connected between the first position and the second position to move between the first position and the second position of the movable mounting part 111. When the base 121 is in the first position, there is a gap between the sealing structure 122 and the product component 2. When the base 121 is in the second position, the sealing structure 122 seals the product functional hole 211 of the product component 2.

[0041] The aforementioned protective fixture 1 includes a carrier 11 and a protective component 12. The base 121 of the protective component 12 is movably connected to the movable mounting part 111 of the carrier 11, and can move between a first position and a second position with the sealing structure 122 disposed on the base 121. When the base 121 is in the second position, the sealing structure 122 can seal the product functional hole 211 of the product component 2, preventing adhesive and wiping agents from entering the interior of the product 21 through the product functional hole 211 during the adhesive bonding process of the product component 2, thereby improving the yield and functional reliability of the product 21.

[0042] It should be noted that the aforementioned product 21 can be a mobile phone, tablet computer, vehicle terminal, medical terminal, wearable device, etc., and this disclosure does not limit this. The aforementioned product component 2 may include a pressure-holding fixture 22 and the product 21 assembled on the pressure-holding fixture 22.

[0043] In some embodiments, such as Figures 1-3 As shown, Figure 1 The dashed arrows in the diagram represent the direction of movement of the base 121 and the product component 2. Along this direction, the movable mounting part 111 is provided with a first limiting member 1113 and a second limiting member 1114, and the base 121 is provided with a third limiting member 1214. When the base 121 is in the first position, the third limiting member 1214 engages with the first limiting member 1113. When the base 121 is in the second position, the third limiting member 1214 engages with the second limiting member 1114. Through the limiting engagement of the first limiting member 1113, the second limiting member 1114, and the third limiting member 1214 along the direction of movement of the product component 2, the range of movement of the base 121 in this direction is limited, preventing excessive pressure from the protective component 12 on the function of the product 21 or causing the protective component 12 to detach from the carrier 11 during movement.

[0044] In the above embodiment, in the direction of movement of the substrate 121, the projections of the first limiting member 1113 and the second limiting member 1114 on the substrate 121 coincide with at least a portion of the third limiting member 1214. When the substrate 121 is in the first position, the third limiting member 1214 abuts against the first limiting member 1113 in the direction of movement of the substrate 121. When the substrate 121 is in the second position, the third limiting member 1214 abuts against the second limiting member 1114 in the direction of movement of the substrate 121. The first limiting member 1113, the second limiting member 1114, and the third limiting member 1214 can be plate-like structures distributed along the direction of movement of the substrate, thereby improving the limiting reliability through the abutment between the plate surfaces.

[0045] The first limiting member 1113 may be equipped with a magnetic element 1115, and the third limiting member 1214 may also be equipped with a magnetic element 1115. When the substrate 121 is in the first position, the magnetic elements 1115 on the first limiting member 1113 and the third limiting member 1214 are magnetically attracted and fixed together. The magnetic attraction and fixation between the first limiting member 1113 and the third limiting member 1214 by the magnetic elements 1115 can ensure that the sealing structure 122 and the product functional hole 211 are fully fitted together, thus preventing sealing failure.

[0046] And / or, the second limiting member 1114 is provided with a magnetic element 1115, and the third limiting member 1214 is provided with a magnetic element 1115. When the substrate 121 is in the second position, the magnetic elements 1115 on the second limiting member 1114 and the magnetic elements 1115 on the third limiting member 1214 are magnetically attracted and fixed. The attraction and fixation of the first limiting member 1113 and the third limiting member 1214 by the magnetic elements 1115 can improve the stopping stability of the sealing structure 122 of the protective component 12 when there is a gap between it and the product component and it is far from the sealing position in the first position, avoiding unnecessary movement.

[0047] In some embodiments, the base 121 may be provided with a handle 1213 to facilitate operation by an operator. For example, the handle 1213 may be U-shaped to facilitate gripping and operation.

[0048] In embodiments of this disclosure, the base 121 may include an adapter 1211 and an assembly structure 1212 fixed to the adapter 1211. The assembly structure 1212 is provided with a mounting groove, which can be used to fix and install the sealing structure 122. The aforementioned third limiting member 1214 may be disposed on the adapter 1211.

[0049] In the above embodiments, the sealing structure 122 includes an end face facing the product component 2, and the end face is provided with a relief recess to avoid excessive compression of the external structure and internal functional components of the product 21. Alternatively, the end face may be configured as a plane according to the structure of the product functional hole 211, and the end face may also be provided with a protruding structure protruding towards the product 21 to match the product functional hole 211 and the product structure near the product functional hole 211.

[0050] For example, when the aforementioned product functional hole 211 is assembled with a structural component protruding from the product 21, the end face of the sealing structure 122 facing the product 21 may be provided with a relief recess that matches the shape of the structural component, so as to avoid excessive compression of the structural component and the internal functional components of the product 21. For example, when the product functional hole 211 is a button hole and the structural component is a button 212, the end face of the sealing structure 122 facing the product 21 may be provided with a relief recess that matches the structure of the button 212, so as to avoid structural compression of the button 212 when sealing the button hole.

[0051] The sealing structure 122 may include an elastic structure disposed on the substrate 121 to improve the sealing reliability between the sealing structure 122 and the product functional hole 211. For example, the material of the sealing structure 122 may be rubber, silicone, etc. Alternatively, the sealing structure 122 may also be made of non-elastic plastic, metal, etc., and this disclosure does not limit this. The materials of the adapter 1211 and the assembly structure 1212 may be metal to improve structural reliability.

[0052] In some embodiments, the product positioning and mounting part 112 may be a groove-shaped structure located on the carrier 11. The edge structure of the groove-shaped structure matches the contour of the product component 2 so as to achieve positioning and assembly of the product component 2 by contour conforming, thereby avoiding the sealing failure of the product functional hole 211 caused by reverse installation and positional offset.

[0053] In some embodiments, the product positioning and mounting part 112 may be a groove-shaped structure located on the carrier 11. The groove-shaped structure is provided with at least one positioning post 1122, so as to realize the positioning and assembly of the product component 2 by cooperating with the positioning hole on the product component 2 through the positioning post 1122, thereby avoiding the sealing failure of the product functional hole 211 caused by reverse installation and positional offset.

[0054] In some embodiments, when the product positioning and mounting part 112 is a groove-shaped structure, the edge structure of the groove-shaped structure can be matched with the contour of the product component 2, and a positioning post 1122 is provided in the groove-shaped structure. Alternatively, the product positioning and mounting part 112 can be other structures that cooperate with the product component 2, such as a limiting protrusion or a limiting hole provided on the carrier 11, and this disclosure does not limit this.

[0055] In some embodiments, the bottom wall of the groove structure may be provided with a hollow structure 1121, which can be used to avoid structural interference with the product component 2, and can also reduce the structural weight of the carrier 11 and reduce the cost of the protective fixture 1.

[0056] In some embodiments, the movable mounting portion 111 may be provided with a slide rail 1111 and a slider 1112 slidably engaged with the slide rail 1111. The base 121 is assembled to the slider 1112 to move relative to the movable mounting portion 111 along the slide rail 1111. The engagement of the slide rail 1111 and the slider 1112 helps to simplify the structure and improve the reliability of the movable connection.

[0057] For example, the aforementioned movable mounting part 111 may be provided with two slide rails 1111 distributed along the movement direction of the product component 2. Slide rails 1111 are respectively fitted with sliders 1112. After the sliders 1112 are assembled with the base 121, they can obtain a stable support effect.

[0058] In other embodiments, the movable mounting part 111 may also be provided with a guide rail and a roller that can roll along the guide rail, and the base 121 and the roller are assembled and cooperated to realize the rolling of the base 121 relative to the movable mounting part 111.

[0059] The aforementioned active mounting part 111 may be a portion of the assembly surface of the carrier 11.

[0060] It should be noted that the product function hole 211 may include at least one of the following: button hole, speaker hole, microphone hole, charging hole, and chip socket.

[0061] In some embodiments, the product positioning and mounting part 112 may include at least two mounting sides, each of which is provided with a movable mounting part 111, so that the protective component 12 can selectively cooperate with any, two or more movable mounting parts 111 according to the protective position requirements of the product component 2.

[0062] For example, product component 2 may include at least two product functional holes 211 located on adjacent sides of product component 2. Product positioning and mounting part 112 includes two adjacent mounting sides that are bent towards each other, and each mounting side is provided with a movable mounting part 111. By using at least two protective components 12 movably assembled at different sides, the product functional holes 211 on different sides of product 21 can be sealed to adapt to products 21 with various distributions of product functional holes 211.

[0063] During the operation of the aforementioned fixture, the product assembly 2, which includes the pressure-holding fixture 22 and the product 21 assembled on the pressure-holding fixture 22, can be placed on the carrier 11 first. The protective assembly 12 is then pushed to seal the sealing structure 122 against the product functional hole 211. Further sealing is achieved by magnetic attraction 1115 of the first limiting member 1113 and the third limiting member 1214, ensuring reliable sealing. After sealing, the adhesive line can be wiped and polished until the desired appearance is achieved. After wiping and polishing, the protective assembly 12 can be pushed to separate the sealing structure 122 from the product assembly 2, and the completed product 21 can be removed. The next piece of product 21 can then be taken out for further wiping and polishing.

[0064] By employing the embodiments of this disclosure, at least 0.5% of defects in the functional holes 211 of the product caused by adhesive polishing can be resolved, and the consumption of auxiliary consumables can be saved, thereby improving the efficiency of production line operations and saving at least 3 people per line.

[0065] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure in any way. Although this disclosure has been disclosed above with reference to a preferred embodiment, it is not intended to limit this disclosure. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this disclosure. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this disclosure without departing from the content of the technical solution of this disclosure shall still fall within the scope of the technical solution of this disclosure.
