[0001] The utility model belongs to the technical field of test fixtures, and particularly relates to a fixture for measuring the size of a notebook computer shell. Background Art

[0002] In manufacturing enterprises, the goal is to ensure the quality stability of products. For a variety of products of different types, especially when measuring the size of products, the process still relies on manual operation. How to operate efficiently and accurately has always been the key concern of enterprises; in the 3C laptop industry, many parts that are too complex to be automated are usually replaced by manual labor, which not only has low efficiency but also high manual measurement errors, and the product quality cannot be effectively guaranteed.

[0003] The traditional operation method is to manually place the product on a profiling fixture, and then use the quick press head on the fixture to fix the product by making it fit the profiling surface of the fixture. Then, a caliper is placed in the caliper groove in the fixture to measure the external dimensions of the product, and the operation is carried out in this way; in the 3C laptop industry, most product shapes are rectangular, and the upper, middle, lower, left, middle, and right of the rectangle need to be measured. Therefore, the multiple quick press heads on the fixture need to be manually opened and closed. At the same time, there is also the problem of whether the product fits firmly with the profiling surface of the fixture. When replacing one product with another after measurement, the product in the fixture needs to be taken out, and the switches of multiple press heads need to be opened and closed again. Thus, when manually measuring every day, the frequency of opening and closing the press head switches and taking in and out the products increases, affecting the fatigue level and efficiency of the operation, and the accuracy of the measurement results cannot be guaranteed either.

Detailed implementation manners

[0027] The present utility model will be further described below in conjunction with the embodiments shown in the drawings.

[0028] As Figure 2 , 3 shown, it is a schematic structural diagram of a jig for measuring the size of a notebook computer shell of the present utility model. The measuring jig includes a substrate 1, a jig plate, a pressing assembly and an adsorption assembly. Among them, the substrate 1 serves as the bottom plate of the entire jig, mainly playing a supporting role, and the operator can carry the substrate 1 to transfer the jig to different places, which is convenient for handling to adapt to different operating occasions.

[0029] The support plate 2 is fixed on the top of the substrate 1, and the jig plate is fixed on the top of the support plate 2. The support plate 2 is used to separate the jig plate and the substrate 1 to ensure that there is enough space between the jig plate and the substrate 1 to provide an installation space for the pressing assembly and the adsorption assembly (the support plate 2 can also be replaced with structures such as support columns or gantry frames).

[0030] As Figure 4 , 5 shown, it is a schematic structural diagram of the jig plate. The jig plate is used to place the product to be measured (such as Figure 1As shown, it is the notebook computer shell product to be measured). The jig plate includes a jig plate body 3, a measurement groove 4, an abutting surface 5, an avoidance groove 6, positioning pins 8, a first stop bar 10, a second stop bar 11, a first through groove 12, and a second through groove 13. The jig plate is a rectangular plate, and fixing holes are opened at the four corners of the jig plate body 3. During actual assembly, fastening bolts are passed through the fixing holes and fixed on the support plate 2 to fix the jig plate body 3.

[0031] By opening fixing holes at the four corners of the jig plate body 3, while satisfying the fixation of the jig plate, the positions of the fastening bolts are close to the four corners of the jig plate body 3 and far from the center position of the jig plate body 3, thus avoiding the actions of pressing, adsorption, and subsequent measurement.

[0032] The jig plate body 3 has two long side edges and two short side edges arranged oppositely. The measurement groove 4 is opened at the top of the jig plate body 3. During actual product measurement, place the Figure 1 product to be measured in the measurement groove 4. The pressing component presses on the top of the product to be measured, and the adsorption component adsorbs on the bottom of the product to be measured. When measuring the product, it is avoided that the product loosens and affects the measurement result.

[0033] The first through grooves 12 are spacedly opened on the long side edges of the jig plate body 3, and the first through grooves 12 on the two long side edges of the jig plate body 3 are arranged oppositely; the second through grooves 13 are spacedly opened on the short side edges of the jig plate body 3, and the second through grooves 13 on the two short side edges of the jig plate body 3 are arranged oppositely. When an operator uses a caliper for measurement, the two measuring jaws of the caliper are placed in the profiling tool caliper slots of the jig plate body 3 (i.e., in the first through groove 12 or the second through groove 13) to measure the maximum outer shape of the product.

[0034] When measuring the length of the product, place the two measuring jaws of the caliper in the second through groove 13 of the jig plate body 3. When measuring the width of the product, place the two measuring jaws of the caliper in the first through groove 12 of the jig plate body 3, and the length and shortness of multiple parts of the product can be measured.

[0035] The avoidance groove 6 is opened at the bottom of the measurement groove 4 and is used to match the convex structure on the bottom surface of the product. After the product is placed in the measurement groove 4, the convex structure on the bottom surface of the product is embedded in the avoidance groove 6. The positioning pins 8 are fixed at the bottom of the measurement groove 4 and are matched with the BOSS posts of the product. After the product is placed in the measurement groove 4, the positioning pins 8 are inserted into the BOSS posts of the product, which not only plays a positioning role for the product but also can play an anti-mistake role to avoid placing the product in the wrong direction.

[0036] The first stop bar 10 is integrally connected to the inner side of one long side edge of the jig plate body 3, the second stop bar 11 is integrally connected to the inner side of one short side edge of the jig plate body 3, and the first stop bar 10 and the second stop bar 11 are perpendicular to each other. AsFigure 5 As shown, both the first stop bar 10 and the second stop bar 11 are located at the lower right corner of the jig plate body 3, and the first stop bar 10 and the second stop bar 11 together form a right-angle stop edge reference.

[0037] When placing the product to be measured into the measurement groove 4, one corner of the product can be aligned with the lower right corner of the jig plate body 3 for placement. There is a right-angle stop edge reference at its lower right corner. After the product aligns with the reference, it is then placed into the measurement groove 4 of the jig plate body 3. The hole positions of the product cooperate with the two positioning pins 8 of the jig plate body 3, enabling precise positioning and ensuring that the product will not be misaligned.

[0038] The abutting surface 5 is inclined and arranged on the side of the measurement groove 4 for matching the peripheral structure of the product.

[0039] The pressing assembly is arranged on the top of the jig plate body 3 for pressing the product in the measurement groove 4. As Figure 6 shown, the pressing assembly includes a through hole 7, a cylinder 14, a pressing plate 16, a threaded hole 17, a pressing bolt 18, and a limit nut 19. The through hole 7 vertically penetrates the jig plate body 3. The through hole 7 is used to avoid the piston rod of the cylinder 14 and prevent interference when pressing the product.

[0040] The cylinder block of the cylinder 14 is fixed on the top of the base plate 1, and the piston rod of the cylinder 14 passes through the through hole 7 and is connected to the pressing plate 16. The cylinder 14 drives the pressing plate 16 to perform a rotational pressing action, thereby pressing the upper surface of the product from above. The cylinder 14 is a commercially available rotary clamping cylinder of the MKB16-10RZ model.

[0041] The threaded holes 17 are spaced apart on the pressing plate 16. The pressing bolts 18 are screwed into the threaded holes 17. By driving the pressing plate 16 to move through the cylinder 14, the pressing bolts 18 are driven to move, completing the pressing and positioning of the product.

[0042] By screwing the pressing bolts 18, the height of the pressing bolts 18 can be adjusted, thereby meeting the pressing requirements of products with different thicknesses and improving versatility.

[0043] The pressing bolt 18 consists of a bolt rod and a bolt head. The limit nut 19 is screwed onto the bolt rod of the pressing bolt 18 and abuts against the lower surface of the pressing plate 16 to prevent the pressing bolt 18 from loosening and shifting due to friction between the pressing bolt 18 and the product.

[0044] The adsorption assembly includes adsorption holes 9 and suction cups. The adsorption holes 9 penetrate the jig plate body 3. The suction cups are arranged in the adsorption holes 9 and are connected to an external air pump through air pipes (the suction cups and the corresponding air pipes are not shown in the figure). After the product is placed in the measurement groove 4, the air pump is turned on, and the air pump adsorbs the product in the measurement groove 4 through the air pipes and the suction cups.

[0045] Place the product to be measured into the fixture plate body 3. One corner of the product can be aligned with the lower right corner of the fixture plate body 1. There is a right-angle edge reference composed of the first stop bar 10 and the second stop bar 11 at the lower right corner of the fixture. After the product is aligned with the reference, place the product into the measurement slot 4. The hole positions of the product are matched with the two positioning pins 8 of the fixture, which can accurately position to ensure that the product will not be displaced.

[0046] Start the air pump, and the suction cup adsorbs the product. The cylinder 14 drives the pressing plate 16 to rotate and press onto the structural surface of the product to ensure that the appearance surface of the product is mutually attached to the profiling surface of the fixture. The measurement personnel can measure according to requirements, and can use a caliper measurement or a projection measurement method. When using a caliper to measure, place the caliper in the first through groove 12 or the second through groove 13 of the fixture, and measure the position of the maximum outer dimension (upper length / middle length / lower length, left width / middle width / right width) of the product. After the measurement is completed, turn off the cylinder 14 and the suction cup to stop the vacuum adsorption state, and the measured product can be removed.

[0047] The measurement personnel no longer continuously turn the handle of the pressing head in the previous quick pressing head method, which improves the efficiency of product placement and measurement, and has a certain anti-fooling performance, which can reduce the operation time and the labor intensity of the personnel, thereby reducing costs.
