Abstract
Description
Technical Field
[0001] The utility model belongs to the field of fixing fixtures, and in particular relates to a clamping and gluing fixture for a notebook computer keyboard panel. Background Art
[0002] Glue dispensing is a very common process in the manufacturing and assembly of laptop computers, which aims to enhance the connectivity, sealing and stability between components.
[0003] The main uses of dispensing include fixing components in the casing to prevent them from loosening, for waterproofing, dustproofing or isolating airflow, improving durability and the service life of equipment, and can also be used as a shock-absorbing material to reduce the impact of mechanical vibration.
[0004] The more commonly used dispensing equipment is divided into manual dispensing guns and large automatic dispensing machines. Manual dispensing guns are suitable for small-batch production or production situations with simpler dispensing requirements, while automatic dispensing machines are more suitable for large-scale production and can better ensure the accuracy and consistency of their dispensing.
[0005] The structure of the laptop keyboard panel is relatively complex. Since it needs to be glued in large quantities, most of them are fixed and glued with a fixture. The more common fixing fixture currently uses negative pressure for direct adsorption and fixation. However, due to the complex structure of the keyboard surface and the thin frame part in the keyboard grid, it is difficult to fix the keyboard grid well if negative pressure adsorption is used. Forcibly adsorbing the frame part may cause deformation of the workpiece. If it is not fixed, the thin frame part of the keyboard grid will bulge upward, making it difficult to perform precise glue dispensing.
[0006] Therefore, a new design is needed that can well fix relatively complex workpieces such as laptop keyboard panels. Utility Model Content
[0007] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a laptop keyboard panel buckling and dispensing fixture.
[0008] In order to solve the above problems, the technical solution adopted by the utility model is as follows:
[0009] A laptop keyboard panel buckle dispensing jig comprises a bottom plate and a fixed plate, wherein the fixed plate is arranged above the bottom plate, a sealed cavity structure is arranged between the bottom plate and the fixed plate, adsorption pores are arranged on the fixed plate, the adsorption pores are connected with the cavity structure, a buckle base movable up and down is arranged on the bottom plate, a plurality of fixed buckles are arranged on the buckle base, and the fixed buckles pass through the fixed plate and extend to the upper surface of the fixed plate.
[0010] The cavity structure comprises a closed air path cavity and a buckle cavity for placing a buckle base, and the air path cavity and the buckle cavity are isolated from each other.
[0011] The buckle base comprises a lifting motor and a fixed cross bar, the fixed cross bar is connected to the lifting motor, and the pull rod is connected to the fixed cross bar.
[0012] The fixed buckle comprises a fixed rod, a buckle and a pull rod, the pull rod is connected to the bottom plate, one end of the buckle is movably connected to the top end of the pull rod, and the middle part of the buckle is movably connected to the fixed rod.
[0013] The fixing rod is an inverted T-shaped structure, and fixing holes are arranged at the left and right ends of the T-shaped structure.
[0014] The fixing rod is connected to the fixing plate through the fixing hole.
[0015] The fixed pressing buckle is arranged corresponding to the keyboard grid frame of the notebook computer keyboard panel.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] The utility model improves the negative pressure adsorption type fixing method in the prior art into a fixing method that performs negative pressure adsorption and pressure buckling simultaneously, effectively solving the problem that the frame of the keyboard grid part on the laptop computer keyboard panel is too narrow to perform negative pressure adsorption, so that the fixture can better fix the keyboard panel of the laptop computer. When dispensing glue, the narrow frame of the keyboard grid part will not bulge upwards, and the problem of deviation in the dispensing position will not occur. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described below in conjunction with specific embodiments.
[0023] like Figure 1 , Figure 2 As shown, the utility model mainly includes a base plate 1 and a fixing plate 2, wherein the fixing plate 2 is arranged above the base plate 1, and after the base plate 1 and the fixing plate 2 are installed, an air path cavity 9 for negative pressure suction and a buckle cavity 10 for placing a fixed buckle 3 and a buckle base 7 are left between the base plate 1 and the fixing plate 2.
[0024] On the side surfaces of the bottom plate 1 and the fixing plate 2, there are also air intake ducts partially connected to the internal air path cavity 9, and the outside of the air intake ducts can be connected to a negative pressure source.
[0025] The panel of the fixing plate 2 is provided with a plurality of through holes for installing fixing components, the lower half of the through holes is connected to the cavity part for negative pressure suction, and a plurality of adsorption holes 8 are provided in a circle around the periphery of the fixing plate 2, that is, corresponding to the part with a larger peripheral surface area of the laptop keyboard surface, and the lower part of the adsorption holes 8 is connected to the closed air path cavity 9, and the panel part with a larger contact area is adsorbed and fixed through the negative pressure suction of the adsorption holes 8.
[0026] Corresponding to the portion where the key grid is arranged in the middle of the laptop keyboard, a plurality of fixed buckles 3 are arranged for buckling according to the specific position of the specific key grid. Below the fixed buckles 3 corresponds to a buckle cavity 10 for placing a buckle base 7, and the buckle base 7 includes a lifting motor 11 and a fixed cross bar 12, wherein the fixed cross bar 12 is connected to the lifting motor 11, and the fixed cross bar 12 can be moved up and down by the action of the lifting motor 11.
[0027] The specific structure of the fixed buckle 3 is as follows Figure 3 As shown, the fixed buckle 3 mainly includes three parts, namely, a fixed rod 4, a buckle 5 and a pull rod 6, wherein the bottom of the pull rod 6 is connected to the fixed cross bar 12, the top of the pull rod 6 is connected to one end of the buckle 5 through a rotating shaft, and the middle part of the buckle 5 is also connected to the fixed rod 4 through a rotating shaft. The structure of the fixed rod 4 is an inverted T-shaped structure, and the left and right sides of the T-shaped structure are fixed to the fixed plate 2 by fixing pins, and the fixed rod 4 is designed as an inverted T-shaped structure to make the buckle 5 more stable when moving. And on the fixed plate 2, each fixed buckle 3 is provided with a through hole matching its shape, so that the buckle 5 part can extend out of the upper surface of the fixed plate 2 for movement.
[0028] When the lifting motor 11 drives the fixed cross bar 12 to move downward, the fixed cross bar 12 drives the pull rod 6 to move downward, and the pull rod 6 simultaneously pulls the connecting shaft of the buckle 5 to move downward. At this time, since the fixed rod 4 is fixed on the fixed plate 2 and will not move along with the movement of the buckle 5, the middle part of the buckle 5 connected to the fixed rod 4 will rotate, and the empty part at the other end of the buckle 5 will be lifted upward, switching to the state where the fixed buckle 3 is relaxed.
[0029] When the lifting motor 11 drives the fixed cross bar 12 to move upward, the pull rod 6 also moves upward, and the movement of the buckle 5 is opposite to that when the pull rod 6 moves downward. The end of the buckle 5 will be pressed down and converted to a clamping state of the fixed buckle 3.
[0030] In actual use, the keyboard panel of the laptop is first placed on the fixed plate 2, and the buckle 5 of the fixed buckle 3 is set according to the keyboard surface to be processed, ensuring that the part of the buckle 5 that is pressed is aligned with the thinner frame part on the keyboard grid. After the keyboard panel is placed, the lifting motor 11 is started to control the movement of the fixed cross bar 12 and drive the buckle 5 to press the keyboard grid part of the keyboard panel onto the fixed plate 2. At the same time, the negative pressure source is started to adsorb the outer part of the keyboard panel onto the fixed plate 2 through the air path cavity 9 and the adsorption air hole 8. At this point, the keyboard panel is fixed and the next step of the glue dispensing process is entered.
[0031] The utility model adds a fixing buckle 3 for the keyboard grid part on the basis of the original negative pressure adsorption fixture, which can effectively prevent the keyboard grid part from bulging upward when the keyboard panel is fixed, and prevent it from affecting the accuracy of the subsequent dispensing process. In addition, the added structure is simple and can be modified on the basis of the existing fixture. Due to the isolation design of the buckle cavity 10 and the air path cavity 9, the modification effect is good and will not affect the original negative pressure adsorption function.
