[0023] Figure 2 This is an exploded view of the fixture in the present invention.

[0024] Figure 3 The utility model provides a capsule size measuring device including a jig. DETAILED DESCRIPTION

[0025] The specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, a jig 8 for securing a bladder skin comprises an upper plate 80, connecting rods, a lower plate 85, and a light-transmitting plate 88. The workbench 7 has a hollow portion 72, with a light-transmitting plate 88 fixedly covering it. The lower plate 85 is fixed to the light-transmitting plate 88, and the upper plate 80 is fixed above the lower plate 85 via a connecting rod. During use, the lower end of the bladder skin (a) is nested in the lower plate 85, abutting the light-transmitting plate 88, while the upper end of the bladder skin (a) is nested in the upper plate 80, expanding the bladder skin (a) into a regular, conical shape, facilitating dimensional measurement.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, as an example, the upper plate 80 is provided with a clearance groove 801, which is convenient for manual or mechanical hand 51 to clamp the upper end of the capsule skin a and remove the capsule skin a from the fixture 8 to complete the unloading. The number of the clearance grooves 801 is two, which are symmetrically arranged on the upper plate 80.

[0028] like Figure 1 、 Figure 2 and Figure 3As shown, the fixture 8 specifically includes a light shielding ring 83. The workbench 7 is provided with a positioning groove 71, with a hollow portion 72 defined at the bottom. During assembly, a light-transmitting plate 88 is securely inserted into the positioning groove 71 with an interference fit. The light shielding ring 83 is fixedly connected to the workbench 7, covering the edge of the light-transmitting plate 88 and thereby securing the plate 88 to the workbench 7. The exposed portion of the light-transmitting plate 88 between the light shielding ring 83 and the lower plate 85 forms a visible area for photographing the capsule a from below.

[0029] like Figure 1 and Figure 2 As shown, preferably, the light-transmitting plate 88 includes but is not limited to tempered glass products, and the light-shielding ring 83 includes but is not limited to steel alloy products. The light-shielding ring 83 is detachably fixed to the workbench 7 by screws or the like to facilitate replacement of the light-transmitting plate 88.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, the light shielding ring 83 serves both to secure the light-transmitting plate 88 and to provide light shielding. Specifically, it prevents light leakage from the edges of the light-transmitting plate 88. Furthermore, the light-transmitting plate 88, in conjunction with the lower plate 85, allows the size of the visible area to be precisely adjusted (the inner diameter of the visible area is equal to the outer diameter of the lower plate 85, which in turn is equal to the inner diameter of the light shielding ring 83). If the inner diameter of the light shielding ring 83 is too small, it can easily obstruct the capsule a, preventing the lower end of the capsule a from nesting within the lower plate 85 and abutting the light-transmitting plate 88. If the inner diameter of the light shielding ring 83 is too large, it can easily allow ambient light to pass through the light-transmitting plate 88, creating backlighting and affecting image quality at the dimensional measurement station, further impacting dimensional measurement. Currently, the thickness of the capsule is typically 4.3 mm to 4.5 mm. Preferably, the width of the visible area (i.e., the difference between its inner and outer diameters) ranges from 8.6 mm to 45 mm.

[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, to facilitate adaptation to bladders of varying heights, the connecting rod should have a telescopic adjustment function. Specifically, the connecting rod comprises an upper rod section 81, a lower rod section 84, and a first fastener 82. The upper plate 80 is fixed to the upper end of the upper rod section 81, and the lower plate 85 is fixed to the lower end of the lower rod section 84. The lower end of the upper rod section 81 is telescopically connected to the upper end of the lower rod section 84, and a first fastener 82 is provided to secure the two.

[0032] like Figure 1 and Figure 2As shown, to facilitate the adaptation to bladder skins a having different diameters at the upper and lower ends, the upper end of the upper rod 81 is inserted into the lower end of the upper plate 80, and the two are detachably fixed together by screws. A connecting plate 841 is provided in the middle of the lower rod 84, and the lower plate 85 is detachably fixed to the connecting plate 841 by screws.

[0033] like Figure 1 、 Figure 2 and Figure 3 As shown, to facilitate the installation and removal of the lower rod section 84 and, consequently, the replacement of the lower disc 85, the lower rod section 84 is detachably fixedly connected to the light-transmitting plate 88. Specifically, the fixture 8 also includes an upper connecting seat 86 and a lower connecting seat 89. A positioning boss 862 is provided at the lower end of the upper connecting seat 86. The upper connecting seat 86 is fixedly connected to the lower connecting seat 89, and the positioning boss 862 is embedded in the light-transmitting plate 88, thereby fixing the light-transmitting plate 88 between the upper connecting seat 86 and the lower connecting seat 89. In other words, the upper connecting seat 86 and the lower connecting seat 89 are detachably fixedly attached to the upper and lower end surfaces of the light-transmitting plate 88.

[0034] like Figure 1 and Figure 2 As shown, preferably, the upper connecting seat 86 and the lower connecting seat 89 are detachably fixed together by screws. Elastic washers 87 are provided between the light-transmitting plate 88 and the upper connecting seat 86 and the lower connecting seat 89 to prevent the light-transmitting plate 88 from being crushed when the screws are tightened on the upper connecting seat 86 and the lower connecting seat 89.

[0035] like Figure 1 and Figure 2 As shown, the lower end of the lower plate 85 is provided with a recess 852 and a positioning hole 851; the upper end of the upper connecting seat 86 is fixedly provided with a latch 861; and the lower connecting seat 89 is equipped with a second fastener 891. After the lower plate 85 is fixedly connected to the connecting plate 841, the lower end of the lower rod 84 is passed through the upper connecting seat 86 and the lower connecting seat 89, so that the recess 852 of the lower plate 85 is nested in the upper end of the upper connecting seat 86 and the positioning hole 851 is nested in the latch 861. The lower end of the lower rod 84 is then locked to the lower connecting seat 89 by the second fastener 891. At this point, the lower plate 85 and the lower rod 84 are detachably fixed to the upper connecting seat 86 and the lower connecting seat 89.

[0036] like Figure 1 and Figure 2 As shown, preferably, the lower end side wall of the lower section rod 84 is provided with a limiting groove 842 that cooperates with the second fastener 891, and the free end of the second fastener 891 is clamped in the limiting groove 842, thereby locking the lower end of the lower section rod 84 to the lower connecting seat 89.

[0037] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model also discloses and protects a bag skin size measuring device, which includes a frame 6 and the fixture 8 described in the structure; the frame 6 is horizontally rotatably provided with a workbench 7, and the workbench 7 is provided with a plurality of fixtures 8 for fixing the bag skin a in a circular distribution, and the frame 6 is provided with a loading station 1, at least one size measuring station and an unloading station 5 in a circular distribution around the workbench 7.

[0038] like Figure 1 、 Figure 2 and Figure 3 As shown, there are three dimension measurement stations, each equipped with a height measuring mechanism 2 , a thickness measuring mechanism 3 and a diameter measuring mechanism 4 .

[0039] The height measurement mechanism 2 mainly includes a three-dimensional line scan camera. Of course, there are many mechanisms or devices for height measurement, and those skilled in the art can refer to the existing technology for implementation, and no excessive restrictions are made here.

[0040] Thickness measurement mechanism 3 includes, but is not limited to, two cameras, one of which is positioned above jig 8 and the other (obscured by frame 6 and workbench 7) below the jig. Of course, numerous mechanisms or devices are available for thickness measurement, and those skilled in the art may refer to existing technologies for implementation, so this is not intended to limit the scope of this disclosure.

[0041] Diameter measurement mechanism 4 includes two cameras, one of which is located above jig 8, and the other (obscured by frame 6 and workbench 7) is located below the jig. Of course, many mechanisms or devices are available for diameter measurement, and those skilled in the art can refer to existing technologies for implementation, so this is not intended to limit the scope of this disclosure.

[0042] like Figure 3 As shown, to enhance safety, loading station 1 is equipped with a grating sensor module 11. If grating sensor module 11 is triggered by an obstruction, the entire system automatically pauses to prevent worker injury. Unloading station 5 is equipped with a robot 51, which removes the capsule skin a from the jig 8, enabling automatic unloading.

[0043] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
