Description

Technical Field

[0001] The utility model relates to the technical field of notebook computers, in particular to a positioning and assembling device for a screen and a plastic part. Background Art

[0002] The current laptop screens are mainly divided into versions with a frame (also known as a bezel version by those skilled in the art) and full-glass versions. The bezel version can be specifically understood as a frame set around the outer edge of the front of the screen, which is also known as a B shell in the art. The LCD screen of the bezel version is usually attached to the A shell (the A shell is understood as a shell set on the back of the screen, which mainly plays the role of installing the screen) with easy-pull adhesive. The front of the LCD screen is clamped by the B shell with adhesive backing and the A shell, and the connection between the B shell and the A shell is usually a snap connection. The full-glass version has no B shell around the front, and is only fixed to the A shell by easy-pull adhesive. In addition, in order to prevent the edge of the LCD screen from warping, a row of plastic parts are usually assembled on the edge of the front of the LCD screen. The shape of the plastic parts is generally a long strip of about 2.0mm*0.5mm*140mm. The plastic parts are fixed to the A shell behind the screen by a plastic snap connection, thereby achieving the purpose of preventing the edge of the screen from warping.

[0003] Specifically, the assembly of the existing LCD screen and the plastic parts on the edge is divided into the following two processes:

[0004] The first step: manually take the double-sided adhesive and attach it to the surface of the plastic part. When attaching the adhesive, the adhesive must not have bubbles or wrinkles, and must not exceed the edge of the plastic part. Since the adhesive is an irregular shape, the adhesive can only be attached in one direction. In actual operation, since the plastic part is relatively soft, manual handling of the plastic part is likely to cause deformation of the plastic part. After attaching the adhesive, you can only use both hands to press the surface of the adhesive to make it completely bonded to the plastic part. The attachment efficiency and yield are relatively low.

[0005] The second step: precisely stick the plastic part with adhesive backing to the edge of the LCD screen. Generally, the distance between the plastic part and the edge of the LCD screen is about 0.3mm, and the precision error is required to be within 0.15mm. Currently, during operation, the plastic part with double-sided tape in step one is manually placed into an ordinary jig, and then the LCD screen and the plastic part in the ordinary jig are bonded together. The plastic part will deform during the back and forth placement, thus affecting the precision of the plastic part fitting to the LCD screen.

[0006] More specifically, if automated equipment is used to complete the assembly work between the LCD screen and the plastic parts, manual loading and unloading is required, and the LCD screen material must be placed on a specific tray, and the plastic parts also need to be placed in a specific posture, which undoubtedly leads to high costs. Therefore, it is necessary to improve the existing technology.

[0007] The above information is presented as background information only to assist with understanding the present disclosure and no determination or admission is made as to whether any of the above may be used as prior art with respect to the present disclosure. Utility Model Content

When using the positioning and assembling device of the present solution, the plastic part can be placed on the plastic part positioning structure 2 first, and the plastic part is limited by the plastic part positioning structure 2 and is not easily deformed. Then, the double-sided adhesive is placed on the double-sided adhesive positioning structure 3.

Finally, the screen is placed on the screen positioning structure 4, so that the screen and the double-sided adhesive are accurately attached. At this time, the accurate assembly of the screen and the plastic part is completed. In other words, the present solution can greatly improve the efficiency and accuracy of assembling the screen through the double-sided adhesive and the plastic part by setting three positioning structures. Compared with the conventional ordinary fixture with only two positioning structures, the assembly efficiency of the present solution is higher.

Compared with the method of using automated equipment, the present solution has higher assembly efficiency and assembly accuracy while having lower cost.

[0043] The specific structures of the plastic part positioning structure 2, the double-sided adhesive positioning structure 3 and the screen positioning structure 4 are described in detail below.

[0044] Please also read Figure 1 and Figure 2 The plastic part positioning structure 2 includes a manual driving mechanism 21 and a positioning block 22, wherein the manual driving mechanism 21 is connected to the base 1, the positioning block 22 is fixed to the base 1, a positioning groove 221 which is open upward is arranged in the positioning block 22, the positioning groove 221 is used to limit the position of the plastic part, and at least one avoidance channel 222 which passes through the positioning groove 221 is arranged on one side of the positioning block 22 which faces the manual driving mechanism 21, and the side wall in the positioning groove 221 which is arranged opposite to the avoidance channel 222 is the positioning surface 223. When in use, the plastic part is first placed in the positioning groove 221, and then the manual driving mechanism 21 passes through the avoidance channel 222 along the first direction (i.e., the X direction) and pushes the plastic part to move, so that the plastic part is finally pushed by the manual driving mechanism 21 to abut against the positioning surface 223, and at this time, the position of the plastic part is jointly restricted by the manual driving mechanism 21 and the positioning surface 223.

[0045] Please also read Figures 1 to 3The manual driving mechanism 21 specifically includes a driving member 211, a slide 212 and a plurality of push blocks 213, wherein the driving member 211 is connected to the base 1, the slide 212 is slidably connected to the base 1 along the X direction, the slide 212 can slide in the X direction by installing a slide rail or a guide rod, and the plurality of push blocks 213 are fixed on the slide 212. When in use, by operating the driving member 211, the slide 212 and the plurality of push blocks 213 can be driven to move in a telescopic linear manner in the X direction, and the push blocks 213 extending in the X direction will pass through the corresponding avoidance channel 222 and push the plastic part in the positioning groove 221 to move, so that the plastic part can finally be positioned on the positioning surface 223. This manual driving mechanism 21 has the advantage of simple structure.

[0046] See also Figure 3 The driving member 211 is preferably an existing quick clamp. Specifically, the driving member 211 includes a fixed seat 2111, an operating handle 2112, a connecting rod 2113, a telescopic rod 2114 and a guide seat 2115, wherein the fixed seat 2111 is fixed on the base 1, the guide seat 2115 is fixed on the fixed seat 2111, the telescopic rod 2114 is inserted into the guide seat 2115 and can be telescopically moved in a straight line along the X direction, and the operating handle 2112 and the fixed seat 2111 are connected by a first axis. Line 2116 is rotatably connected with the rotating shaft, one end of the connecting rod 2113 is rotatably connected with the operating handle 2112 with the second axis 2117 as the rotating shaft, and the other end of the connecting rod 2113 is rotatably connected with the telescopic rod 2114 with the third axis 2118 as the rotating shaft, and the first axis 2116, the second axis 2117 and the third axis 2118 are parallel to each other and are perpendicular to the X direction, and the end of the telescopic rod 2114 away from the connecting rod 2113 is fixedly connected to the above-mentioned slide seat 212. During operation, it is only necessary to rotate the operating handle 2112 in the positive direction of the X direction to drive the telescopic rod 2114 to move in the positive direction of the X direction, thereby pushing the slide 212 and the plurality of push blocks 213 to move together in the positive direction of the X direction, and then positioning the plastic part on the positioning surface 223. When the plastic part and the screen are assembled, the operating handle 2112 can be rotated in the opposite direction of the X direction, so that the telescopic rod 2114 pulls the slide 212 and the plurality of push blocks 213 in the opposite direction of the X direction to retreat together in the opposite direction of the X direction, so that the semi-finished product with the plastic part attached to the edge of the screen can be unloaded outward.

[0047] See also Figure 2The positioning assembly device also includes a first sensor 5 for detecting whether a plastic part is placed in the positioning groove 221. The first sensor 5 can be designed to be fixed on the positioning block 22. In addition, an adsorption hole 224 is provided at the bottom of the positioning groove 221. When working, when the first sensor 5 detects that the plastic part has been placed in the first sensor 5, the adsorption hole 224 will adsorb the bottom surface of the plastic part, making the plastic part more stable in the positioning groove 221, thereby further improving the assembly accuracy between the plastic part and the double-sided adhesive.

[0048] See also Figure 2 The double-sided adhesive positioning structure 3 includes a plurality of positioning posts 31, which are arranged on the outer side of the positioning block 22 and are fixedly connected to the base 1. The plurality of positioning posts 31 are used to jointly limit the position of the double-sided adhesive. The double-sided adhesive of the present application includes a release film and a double-sided adhesive body bonded to the release film. The release film is provided with positioning holes that cooperate with the positioning posts 31. The release film is precisely positioned by the plurality of positioning posts 31 to ensure accurate assembly of the double-sided adhesive body and the plastic part. When the double-sided adhesive body is bonded to the plastic part and the plastic part is assembled with the screen, the release film needs to be torn off so that the subsequent screen can be bonded to the plastic part through the other side of the double-sided adhesive body.

[0049] Please also read Figure 1 , Figure 2 and Figure 4 The screen positioning structure 4 includes a plurality of limit blocks 41 for limiting the outer edge of the screen. The plurality of limit blocks 41 are arranged circumferentially and together form a limit area 42 for placing the screen. Figure 4 The rectangular dotted frame in the figure is the limiting area 42. The positioning block 22 is arranged in the limiting area 42 and is arranged adjacent to the limiting block 41 on one side, so that when the screen is placed in the limiting area 42, the outer edge of the screen can be bonded to the plastic part. Preferably, a second sensor 6 can be fixed in the limiting area 42 of the base 1, and the second sensor 6 detects whether a screen is placed in the limiting area 42, thereby improving the degree of automation of the operation. At the same time, the second sensor 6 can be connected to the adsorption function signal, that is, when the second sensor 6 detects that a screen is placed in the limiting area 42, the vacuum adsorption of the adsorption hole 224 can be automatically cut off, so that the screen can be removed immediately after the assembly of the screen and the plastic part is completed. In addition, the base 1 is provided with two penetrating notches 11 at positions corresponding to the limiting area 42. The two notches 11 are arranged opposite to each other, and one of the notches 11 is used to avoid the left hand of the operator, and the other notch 11 is used to avoid the right hand of the operator. By providing the two notches 11, it is convenient for the operator to place the screen in the limiting area 42 with both hands, and it is also convenient for the operator to take the screen in the limiting area 42 out, which has the advantage of easy operation.

[0050] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
