Description

Technical Field

[0001] The invention relates to a testing device, in particular to a packaging quality testing device for product design. Background Art

[0002] Product packaging can protect products during transportation, handling, storage and other links, and prevent damage such as collision, extrusion, moisture, and light. For some special types of products, such as household appliances, there is a problem that is often overlooked, that is, household appliances are often large in size, heavy in weight, and have complex internal structures, which leads to uneven gravity distribution on the front and back sides and inconsistent center of gravity positions during the packaging process. Therefore, when designing packaging, it is necessary to consider the imbalance of the center of gravity distribution and make adjustments. Otherwise, packaging with an unstable center of gravity is prone to tilting, rolling, or even inverting during transportation, which can cause product damage and even chain reaction damage to surrounding goods in severe cases. On the other hand, during the transportation of products, uphill and downhill and bumpy roads are often encountered, which makes product packaging face more severe tests. It can be seen that it is very necessary to conduct quality inspection on the designed product packaging, which can provide a basis for the optimization of product packaging.

[0024] like Figures 1 to 6 As shown, an embodiment of the present invention provides a packaging quality inspection device for product design, including an operating table 1 and a turntable 2. Support outer shafts 17 are installed on the front and rear sides of the operating table 1, and support sleeves 22 that are compatible with the support outer shaft 17 are symmetrically arranged on the front and rear sides of the outer wall of the turntable 2. The turntable 2 is rotatably arranged on the top of the operating table 1 through the support outer shaft 17 and the support sleeve 22, and the rotation axis is along the diameter direction of the turntable 2.

[0025] Four radial slots 4 are evenly arranged along the circumference of the turntable 2. The radial slots 4 are connected vertically. A vertical rod 6 is slidably arranged in each radial slot 4. Specifically,

The first slider 8 and the radial groove 4 have a similar matching structure. The strip protrusions cooperate with the transverse guide grooves, so that the vertical rod 6 can slide smoothly along the radial groove 4.

[0027] A clamping drive assembly and a vibration drive assembly are provided below the turntable 2. The clamping drive assembly is used to drive the four vertical rods 6 to move synchronously toward or away from each other to clamp the packaged product. Specifically,

[0028] The clamping drive assembly includes a gear 12 and a first motor 3 fixedly arranged at the bottom of the operating table 1. The inner cavity of the turntable 2 is a hollow structure, and the gear 12 is arranged in the inner cavity of the turntable 2. A connecting shaft 13 is connected to the bottom of the gear 12, and the bottom of the connecting shaft 13 is connected to the power end of the first motor 3. In order to ensure that the gear 12 has good stability during the rotation process, the top of the gear 12 is connected to the turntable 2 through a supporting shaft 5, which plays a good supporting role without affecting the rotation of the gear 12. A circular through hole 21 adapted to the supporting shaft 5 is opened at the center of the top of the turntable 2, and the upper end of the supporting shaft 5 is rotatably matched with the circular through hole 21. In this embodiment, a circle of first limiting ring 51 is set on the outer wall of the upper end of the supporting shaft 5, and a limiting support groove adapted to the first limiting ring 51 is opened on the inner wall of the circular through hole 21. The first limiting ring 51 is embedded in the limiting support groove to ensure the smooth rotation of the gear 12.

[0029] Two groups of racks 11 staggered up and down are meshed around the outer wall of the gear 12. The same group of racks 11 includes two opposite and parallel racks 11 to avoid mutual interference among the four racks 11. The ends of the racks 11 are connected to the corresponding sliders through the supporting cross plates 10, wherein the tops of the front and rear groups of supporting cross plates 10 are connected to the second slider 9, and the tops of the left and right groups of supporting cross plates 10 are connected to the first slider 8.

[0030] When the gear 12 rotates, the four racks 11 are driven to move synchronously laterally, so that the four vertical rods 6 are synchronously moved closer to or farther from each other, thereby enabling the four vertical rods 6 to clamp the packaged product.

[0031] A strain gauge 7 for detecting pressure is arranged on the top of the inner side of the vertical rod 6, and a control panel 16 (the control panel 16 is prior art) is arranged on the operating table 1. The pressure value detected by the strain gauge 7 is displayed on the control panel 16 and data is recorded.

[0032] The vibration drive assembly includes a second motor 14 fixed to the outer wall of the front side of the operating table 1, the power end of the second motor 14 is connected to a power shaft 141, the outer wall of the power shaft 141 is sleeved with a support bearing 142, the support bearing 142 is installed on the operating table 1, and the other end of the power shaft 141 is installed with an eccentric wheel 143.

[0033] Vibration plates 23 are symmetrically arranged on the outer walls of the left and right sides of the turntable 2, and grooves are provided at the bottom of the vibration plates 23. The outer wall of the eccentric wheel 143 contacts the groove at the bottom of one of the vibration plates 23. A connecting block 24 is arranged on the top of the vibration plate 23, and a vibration spring 25 is connected to the top of the connecting block 24, and the top end of the vibration spring 25 is connected to the inner wall of the operating table 1.

[0034] The outer wall of the supporting horizontal plate 10 is provided with an elastic component 15, which is used to cooperate with the inner wall of the operating platform 1 when the vertical rod 6 is retracted to prevent the vertical rod 6 from excessive translation and causing collision with the inner wall of the radial slide 4. Specifically,

[0035] The elastic component 15 includes a fixed cylinder 152 installed on the outer wall of the supporting horizontal plate 10, and the inner wall of the fixed cylinder 152 is provided with an active cavity 153, and a top block 151 is slidably arranged in the active cavity 153, and the top block 151 extends to the outside of the fixed cylinder 152. A second limiting ring 155 is arranged on the outer wall of the inner end of the top block 151 to prevent the top block 151 from sliding out of the fixed cylinder 152. A return spring 154 is connected to the inner end surface of the top block 151, and the other end of the return spring 154 is connected to the inner bottom of the fixed cylinder 152. The return spring 154 can make the top block 151 have a certain buffering force, and play a good buffering role.

[0036] The method for using the packaging quality inspection device for product design provided by the embodiment of the present invention is as follows:

[0037] The packaged product to be tested is placed on the turntable 2. The four vertical rods 6 are driven by the gear 12 and move closer or farther from each other with the help of the rack 11 to clamp the packaged product. The strain gauge 7 fits the outer wall of the packaged product. The second motor 14 is started. With the support of the support bearing 142, the power shaft 141 drives the eccentric wheel 143 to rotate. The eccentric wheel 143 drives the vibration plate 23 to vibrate and tilt with the assistance of the vibration spring 25 to simulate the bumpy road section during transportation. When the tilt angle is the maximum, it can also simulate the uphill and downhill state during transportation. The packaged product placed on the turntable 2 tilts accordingly, thereby simulating the transportation state. The four groups of strain gauges 7 perform force detection on the outer wall of the packaged product. According to the four groups of pressure detection values, it is determined whether the center of gravity of the packaged product is offset. At the same time, based on this, the position of the product during packaging is adjusted to reduce the offset of the center of gravity, so as to ensure that there will be no tilting, rolling or even inversion during transportation, which will cause damage to the home appliance products.
