Description

Technical Field

[0001] This utility model relates to the field of keyboard processing fixtures, and in particular to a micro-fixing fixture for dispensing adhesive in the keyboard area. Background Technology

[0002] In the laptop manufacturing process, the keyboard area is typically fixed to the laptop casing using an adhesive bonding process. For example... Figure 1 As shown, the keyboard frame includes keyboard frame A, keyboard frame B, and keyboard frame C. Keyboard frames A and C are located on either side of keyboard frame B, and the width of keyboard frame B is greater than the width of keyboard frames A and C. Due to the pursuit of lightweight design in laptops, the keyboard frame structure in the keyboard area is thin (0.5–1 mm) and the key spacing is narrow (1–2 mm), making this area susceptible to stress during processing and prone to warping. Traditional adhesive fixtures primarily use pressure blocks that match the shape of the keyboard frame to fix the keyboard frame to the laptop casing, fixing it by vertical pressure. Alternatively, negative pressure adsorption can be used to fix the keyboard frame, avoiding interference from physical pressure blocks.

[0003] In the process of developing the existing technology, the inventors discovered that:

[0004] Because the keyboard frame is narrow, the pressure block needs to be extremely thin to fit the corresponding area. However, an extremely thin structure lacks rigidity, making the keyboard frame prone to deformation under pressure, hindering even force application. Furthermore, a large pressure block occupies space, restricting the movement path of the dispensing needle and increasing the risk of collisions, resulting in uneven glue application or scratches. In negative pressure adsorption, the diameter of a conventional suction nozzle is generally larger than the gaps between the keyboard frame keys, making it ineffective at adsorbing the central area and causing uncorrectable localized warping. Increasing the adsorption force may deform the keyboard frame, while insufficient adsorption force cannot guarantee flatness, affecting the consistency of glue dispensing.

[0005] Therefore, this application provides a fixing fixture that reduces keyboard frame deformation and facilitates glue dispensing, in order to solve the problem in the prior art that the keyboard frame using contoured pressing blocks or negative pressure vacuum adsorption has poor flatness and is easy to deform, which leads to poor glue dispensing consistency. Utility Model Content

[0006] The purpose of this invention is to provide a fixing fixture that reduces keyboard area deformation and facilitates adhesive dispensing, thereby solving the problem of poor flatness and easy deformation of the keyboard area caused by the use of contour pressing blocks or negative pressure vacuum adsorption in the prior art, which leads to poor adhesive dispensing consistency.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a keyboard area dispensing micro-fixing fixture, specifically comprising: a base plate fixture with a placement groove for placing a laptop shell and a keyboard frame placed on the laptop shell, the keyboard frame including keyboard frame A, keyboard frame B, and keyboard frame C arranged in sequence; a plurality of cylinder pressing block assemblies I arranged around the placement groove for positioning the keyboard frame located in the placement groove by rotating cylinders; abutment blocks arranged around the placement groove and located between the cylinder pressing block assemblies I for horizontally limiting the laptop shell on which the keyboard frame is placed; a plurality of through holes are opened on the placement groove end face of the base plate fixture corresponding to the position of the keyboard frame B, and the base plate fixture is also provided with cylinder pressing block assemblies II at the through hole positions for swinging pressing block II by lifting cylinders to swing and press the keyboard frame B onto the laptop shell.

[0008] Preferably, the placement groove end face of the base plate fixture is further provided with a positioning boss for positioning the notebook shell and keyboard frame B.

[0009] Preferably, the cylinder pressure block assembly includes at least a rotary cylinder and a pressure block connected to the rotary cylinder.

[0010] Preferably, the cylinder pressure block assembly two includes at least a swing pressure block two passing through a through hole, a lifting cylinder connected to the swing pressure block two, and a fixed plate. The swing pressure block two has a movable groove. The lifting cylinder is connected to the swing pressure block two through a movable rod inserted into the movable groove. The fixed plate is hinged to one end of the swing pressure block two.

[0011] Preferably, the distance between the positioning boss and the keyboard frame B is between 0.01mm and 0.02mm.

[0012] Preferably, the gap between the notebook casing and the side wall of the fixture placement slot is between 0.1mm and 0.2mm.

[0013] Preferably, the plurality of through holes specifically includes a central through hole located at the center of the placement groove and non-central through holes distributed in a rectangular array at predetermined intervals from the central through hole, and cylinder pressure block assembly II is respectively provided in the central through hole and the non-central through hole.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] The keyboard area dispensing micro-fixing fixture provided in this application uses a cylinder pressure block assembly one and a top block to fix the keyboard frame in the circumferential direction. At the same time, the through hole on the end face of the placement slot is used to set up a cylinder pressure block assembly two to press the keyboard frame B down onto the laptop shell. This avoids the problems of easy deformation of the keyboard frame when pressing down with the contouring pressure block, large space occupation affecting the movement of the dispensing needle, and ineffective negative pressure adsorption, which lead to poor flatness and easy deformation of the keyboard frame. This ensures the consistency of glue dispensing by the dispensing needle. Attached Figure Description

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Please see Figures 2 to 4 This utility model provides a keyboard area adhesive micro-fixing fixture 100, a base plate fixture 1 with a placement groove 11 for placing a notebook shell 5 and a keyboard frame 6 placed on the notebook shell 5. The keyboard frame 6 includes keyboard frames A61, B62 and C63 arranged in sequence; a plurality of cylinder pressing block assemblies 2 surrounding the placement groove 11 for pressing down the periphery of the keyboard frame 6 in the placement groove 11 by rotating cylinder 21; abutment blocks 3 surrounding the placement groove 11 and located between the cylinder pressing block assemblies 2 for horizontally limiting the notebook shell 5 on which the keyboard frame 6 is placed; a plurality of through holes 12 are opened on the end face of the placement groove 11 of the base plate fixture 1 corresponding to the position of the keyboard frame B62, and a second cylinder pressing block assembly 4 is also provided at the position of the through hole 12 for swinging the second 42 of the second 42 driven by lifting cylinder 41 to press down the keyboard frame B62 on the notebook shell 5.

[0031] Specifically, in this application, the base plate fixture 1 is made of phenolic resin material, i.e., bakelite. A placement groove 11 is milled at the center position using processing equipment to place the notebook casing 5 and the keyboard frame 6 placed on the notebook casing 5.

[0032] Several cylinder pressing block assemblies 2, arranged around the placement slot 11, are mainly used to press down and position the keyboard frame 6 circumferentially. Specifically, the base plate fixture 1 has mounting holes for the cylinder pressing block assemblies 2. Each cylinder pressing block assembly 2 includes a rotary cylinder 21 and a pressing block 22. The rotary cylinder 21 is inserted into the mounting hole, and then the pressing block 22 is connected to the rotary cylinder 21 to install the cylinder pressing block assembly 2. It can be understood that when the cylinder pressing block assembly 2 needs to press down on the keyboard frame 6, the rotary cylinder 21 rotates, causing the pressing block 22 to press against the keyboard frame 6. Conversely, when the rotary cylinder 21 rotates, it drives the pressing block 22 to rotate, and the pressing block 22 no longer presses down on the keyboard frame 6. It is understandable that several cylinder pressure block components 2 are set around the keyboard frame 6, which basically achieves the fixed positioning of the smaller keyboard frames A61 and C63 located on both sides of the keyboard frame B62. At the same time, the two sides of the keyboard frame B62 that are not connected to the keyboard frames A61 and C63 are also basically fixed in position through the setting of the cylinder pressure block components 2.

[0033] In addition, the pressure block 22 is made of PEEK material, which makes it less prone to slipping when it comes into contact with the keyboard frame 6.

[0034] The abutment block 3, located between the cylinder pressure block assembly 2 and surrounding the placement groove 11, is used to horizontally limit the laptop casing 5 on which the keyboard frame 6 is placed. The abutment block 3 is mainly used to prevent the laptop casing 5 and the keyboard frame 6 inside the laptop casing 5 from moving horizontally, thereby improving the consistency of adhesive application.

[0035] Specifically, a stop block 3 is set between the cylinder pressure block assembly 2 to achieve fixed positioning of the laptop shell 5.

[0036] It should be noted that the abutment block 3 is also provided with a movable groove 421 for connecting to the base plate fixture 1. The base plate fixture 1 is provided with a connecting hole, and the movable groove 421 is inserted into the connecting hole to achieve fixation. Moreover, the movable groove 421 allows the abutment block 3 to move back and forth to abut against the notebook casing 5, and after abutting, it is fixed by the connecting screw.

[0037] Specifically, the gap between the laptop casing 5 and the side wall of the fixture placement slot 11 is between 0.1mm and 0.2mm. This gap allows the laptop casing 5 to be placed in the placement slot 11, and the abutment block 3 restricts the horizontal displacement of the laptop casing 5, thereby restricting the horizontal movement of the keyboard frame 6. The cylinder pressure block assembly 2 then presses down on the keyboard frame 6 to achieve vertical fixation.

[0038] Based on this, the present application provides several through holes 12 at the bottom of the placement groove 11 of the base plate fixture 1 corresponding to the position of the keyboard frame B62. The base plate fixture 1 is also provided with a cylinder pressing block assembly 4 at the position of the through hole 12, which is used to drive the swing pressing block 42 to swing down and press the keyboard frame B62 onto the notebook shell 5 by the lifting cylinder 41.

[0039] Specifically, since the keyboard frame B62 in the keyboard frame 6 is wide, and the keyboard frame 6 is thin (0.5-1mm) and has a narrow key spacing (1-2mm), this application also provides a cylinder pressure block assembly 4 to fix it.

[0040] Specifically, such as Figure 5 As shown, the cylinder pressure block assembly 2 4 includes at least a swing pressure block 2 42 passing through the through hole 12, a lifting cylinder 41 connected to the swing pressure block 2 42, and a fixing plate 43. The swing pressure block 2 42 has a movable groove 421. The lifting cylinder 41 is connected to the swing pressure block 2 42 through a movable rod 422 inserted into the movable groove 421. The fixing plate 43 is hinged to one end of the swing pressure block 2 42.

[0041] It is understandable that when the cylinder pressing block assembly needs to press down on the keyboard frame 6, the lifting rod of the lifting cylinder 41 lowers, and the movable rod 422 connected to the lifting cylinder 41 moves downward in the movable groove 421. Under normal circumstances, the swing pressing block 42 is pulled downward as a whole by the movable rod 422. However, since one end of the swing pressing block 42 is hinged to the fixed plate 43, its other end swings downward, thereby pressing down on the keyboard frame 6. Conversely, the swing pressing block 42 is raised.

[0042] It should also be noted that the swing block of the cylinder pressure block assembly 4 is located in the through hole 12, the lifting cylinder 41 is installed on the base plate fixture 1 by screws, and the fixing plate 43 is located in the groove in the base plate fixture 1 and connected to the lifting cylinder 41 by screws.

[0043] The through holes 12 specifically include a central through hole 121 located at the center of the placement groove 11 and non-central through holes 122 distributed in a rectangular array at predetermined intervals from the central through hole 121. The through holes 12 are mainly used to distribute the cylinder pressure block assembly 4 on the keyboard frame B62 to improve the flatness of the keyboard frame 6, reduce deformation, and ensure the consistency of glue dispensing by the dispensing needle.

[0044] Furthermore, the end face of the placement groove 11 of the base plate fixture 1 is also provided with a positioning boss 13 for positioning the notebook shell 5 and the keyboard frame B62.

[0045] Specifically, the positioning boss 13 is mainly used for positioning the laptop casing 5 and the keyboard frame B62. In one embodiment provided in this application, the distance between the positioning boss 13 and the keyboard frame B62 is between 0.01mm and 0.02mm, preferably 0.01mm.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
