[0015] Beneficial effects of the present invention:

[0016] By controlling the refrigerator in the box to work, the inside of the box is cooled down to simulate the use scenario of the refrigerator drawer in the low-temperature environment of the refrigerator freezer area; and by detecting the repeated friction contact between the drawer and the ice cubes fixed on the electric clamp 1 and the electric clamp 2 to simulate the actual use scenario of the refrigerator drawer being pulled out in the refrigerator freezer area, the reliability of the drawer performance test results is improved.

[0017] The scraper rod contacts the ice cubes fixed by the electric clamp 1 and the electric clamp 2 and scrapes the surface of the ice cubes. The scraper rod scrapes a number of fine scratches on the surface of the ice cubes to keep the surface rough, thereby preventing the detection drawer from gradually polishing it smooth during the pulling process and reducing the friction between the inner wall of the box and the detection drawer. The width of the scraper rod is set to 2-4mm, so the scratches on the surface of the ice cubes fixed by the electric clamp 1 and the electric clamp 2 are relatively small. When scraping, the ice cubes will not be damaged on a large scale, thereby ensuring the continuous use of the ice cubes.

[0018] By placing an annular magnet in the detection drawer to increase the overall weight of the detection drawer, the friction between the detection drawer and ice cubes is improved to ensure the authenticity of the drawer pull-out detection; and when the telescopic cylinder drives the detection drawer to be pulled out and pulled out repeatedly, the annular magnet in the detection drawer collides with the detection drawer under the action of inertia to simulate the situation when the refrigerator drawer is actually pulled out and used, in which harder ingredients such as ribs will collide with the drawer, thereby improving the reliability of the drawer pull-out detection results.

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Example 1

[0031] A finished product performance testing equipment for home appliance injection molding parts, such as Figure 1-Figure 5 As shown, it includes a heat-insulating shell 1, a telescopic cylinder 2 and an electric clamp 3; the heat-insulating shell 1 is provided with a warehouse door 01; the right side of the heat-insulating shell 1 is fixedly connected to the telescopic cylinder 2; the telescopic part of the telescopic cylinder 2 is fixedly connected to the electric clamp 3;

[0032] It also includes a box body 4, a partition 5, an electric push rod 1 6, an electric clamp 1 7, a mounting frame 8, an electric push rod 2 9, an electric clamp 2 10, a collection box 11 and a cleaning unit; the box body 4 is fixedly connected to the inside of the heat-insulating shell 1, and a refrigerator is arranged inside the box body 4; the box body 4 is fixedly connected to a partition 5; a plurality of electric push rods 1 6 are fixedly connected to the front and rear sides of the box body 4; the corresponding telescopic parts of the plurality of electric push rods 1 6 are each fixedly connected to an electric clamp 1 7, and the electric clamp 1 7 is slidably connected to the box body 4; the box body 4 is provided with a plurality of through slots 02; a plurality of electric push rods 2 9 are fixedly connected to the bottom of the box body 4; all the telescopic parts of the electric push rods 2 9 are fixedly connected to a mounting frame 8; the mounting frame 8 is fixedly connected to a plurality of electric clamps 2 10, and the electric clamps 2 10 are slidably connected in the through slots 02; the box body 4 is slidably connected to the collection box 11; the box body 4 is connected to a cleaning unit.

[0033] A monitoring camera is provided at the bottom of the partition 5, through which the thickness of the ice fixed by the electric clamp 1 7 and the electric clamp 2 10 can be monitored in real time, which is convenient for subsequent observation and replacement.

[0034] The working steps of the above embodiment are as follows: initially, the door 01 is opened manually, and then the injection molded detection drawer 100 is placed between the box body 4 and the partition 5. Figure 2As shown, the telescopic cylinder 2 is then controlled to drive the electric clamping plate 3 to move, and the electric clamping plate 3 is controlled to rotate and hook the detection drawer 100. Subsequently, the compartment door 01 is manually closed, and then the refrigerator in the box body 4 is controlled to work to cool down the inside of the box body 4 to simulate the use scenario of the refrigerator drawer in a low-temperature environment in the refrigerator freezer area; at the same time, when the refrigerator drawer is used in the refrigerator freezer area, since frost and ice will condense in the refrigerator freezer area, when people pull and draw the drawer, the drawer will rub against the frost and lumps, causing The drawer is subjected to additional wear during the pulling process. Therefore, before the detection drawer 100 is placed between the box body 4 and the partition 5, an ice cube is manually placed on each electric clamp 1 7 and the electric clamp 2 10, and the electric clamp 1 7 and the electric clamp 2 10 are controlled to clamp and fix the ice cube; when the detection starts, the electric push rod 1 6 is first controlled to drive the electric clamp 1 7 and the fixed ice cube to move toward the detection drawer 100, so that the ice cube contacts the side of the detection drawer 100, and the electric push rod 2 9 is controlled to drive the mounting frame 8 and the electric push rod 2 9 to move ... clamp 2 9. The movable clamp 10 and the fixed ice cube move upward, so that the ice cube contacts the bottom surface of the detection drawer 100. At this time, the telescopic cylinder 2 is controlled to drive the electric clamp 3 and the detection drawer 100 to move, so that the detection drawer 100 is repeatedly pulled out and tested between the box body 4 and the partition 5. In the process of pulling out, the detection drawer 100 is repeatedly rubbed and contacted with the electric clamp 1 7 and the ice cube fixed on the electric clamp 2 10, so as to simulate the actual use scenario of the refrigerator drawer being pulled out in the refrigerator freezer area, thereby improving the drawer performance detection The reliability of the results; and during the detection process, as the detection drawer 100 is continuously and repeatedly pulled, the ice cubes in friction contact with the detection drawer 100 will gradually be worn. Therefore, when the detection drawer 100 is pulled to the set cycle, the electric push rod 1 6 and the electric push rod 2 9 are regularly controlled to drive the electric clamp 1 7 and the electric clamp 2 10 to move respectively, so that the electric clamp 1 7 and the electric clamp 2 10 regularly drive the fixed ice cubes to move closer to the detection drawer 100, ensuring that the ice cubes can always be in contact and friction with the detection drawer 100.

[0035] Example 2

[0036] On the basis of Example 1, Figure 2-Figure 3 and Figure 6-Figure 8 As shown, the cleaning unit includes an electric telescopic rod 201, a T-shaped plate 202, a connecting frame 203 and a scraper 204; the box body 4 is fixedly connected to the electric telescopic rod 201, and the electric telescopic rod 201 is fixedly connected to the heat-insulating shell 1; the telescopic part of the electric telescopic rod 201 is fixedly connected to the T-shaped plate 202, and the T-shaped plate 202 is slidably connected on the inner wall of the box body 4; the T-shaped plate 202 is fixedly connected to the connecting frame 203; the connecting frame 203 is fixedly connected to a plurality of scraper rods 204, and the scraper rods 204 are in contact with the inner wall of the box body 4.

[0037] It also includes a second connecting frame 205 and a first water-absorbing sponge 206; the T-shaped plate 202 is fixedly connected to the second connecting frame 205; and the second connecting frame 205 is rotatably connected to a plurality of first water-absorbing sponges 206.

[0038] It also includes a mounting plate 211 and a second absorbent sponge 212; a mounting plate 211 is fixedly connected to the front and rear sides of the box body 4; each mounting plate 211 is rotatably connected to a second absorbent sponge 212, and two mounting plates 211 are rotatably connected to another second absorbent sponge 212.

[0039] There is a gap between the electric clamp 10 and the through slot 02, so that the water melted by the friction when the detection drawer 100 is pulled out can be discharged in time through the gap between the electric clamp 10 and the through slot 02, thereby accelerating the removal of water.

[0040] The width of the scraper rod 204 is set to 2-4 mm. The scraper rod 204 scrapes the surface of the ice fixed by the electric clamp 1 7 and the electric clamp 2 10 with small scratches. When scraping, it will not cause large-scale damage to the ice, ensuring that the ice can be used continuously.

[0041] The scraper rod 204 is made of rubber material, and will not cause damage to the inner wall surface of the box body 4 when scraping it.

[0042] On the basis of the above-mentioned embodiment, during the initial pull-out detection process, the detection drawer 100 continuously rubs against the ice cubes fixed by the electric clamp 1 7 and the electric clamp 2 10, which will gradually polish them smooth, thereby reducing the friction between the ice cubes and the detection drawer 100, thereby affecting the detection result of the durability of the detection drawer 100, and as the detection drawer 100 repeatedly rubs in contact with the box body 4, the heat generated by the friction will melt the ice into water, and the melted water will take a certain amount of time to condense into ice again. The melted water will exist between the ice cubes and the detection drawer 100, as well as between the box body 4 and the detection drawer 100, thereby reducing the friction between the ice cubes and the detection drawer 100. Therefore, during the pull-out detection process of the detection drawer 100, the electric telescopic rod 201 is simultaneously controlled to drive the T-shaped plate 202 and other connected parts to move together, such as Figure 7 and Figure 8As shown, when the detection drawer 100 is pulled and moved to the right, the electric telescopic rod 201 is controlled to drive the T-shaped plate 202 and other connected parts to move to the right together, and the scraper rod 204 contacts the ice cubes fixed by the electric clamp 1 7 and the electric clamp 2 10, and scrapes the surface of the ice cubes. The scraper rod 204 scrapes a number of fine scratches on the surface of the ice cubes, so that the surface is always in an uneven state, preventing the detection drawer 100 from gradually polishing it smooth during the pulling process, reducing the friction between the inner wall of the box body 4 and the detection drawer 100, and the scraper rod 204 width is set to 2-4mm, the scratches on the surface of the ice cubes fixed by the electric clamp 1 7 and the electric clamp 2 10 are small, and when scraping, it will not cause large-scale damage to the ice cubes, ensuring that the ice cubes can Continuous use; and, during the pull-out detection process, the ice cubes are in frictional contact with the detection drawer 100, and part of the ice will be melted into water. When the water-absorbing sponge 206 is driven by the electric telescopic rod 201 to move with the detection drawer 100, the water-absorbing sponge 206 passes through the surface of the ice cube fixed by the electric clamp 1 7 and the electric clamp 2 10, as well as the inner wall of the box body 4, and absorbs the melted water on the surface, so that its surface always remains relatively dry, preventing the melted water from reducing the friction between the ice cube and the detection drawer 100; and, there is a gap between the electric clamp 2 10 and the through groove 02, so that the water melted by the friction of the detection drawer 100 when it is pulled out can also be discharged in time through the gap between the electric clamp 2 10 and the through groove 02, and collected in the collection box 11 to speed up the discharge of water.

[0043] At the same time, when the detection drawer 100 is pulled out of the box body 4, the absorbent sponge 212 arranged on the mounting plate 211 can contact the side and bottom of the detection drawer 100, absorb and remove water on the side and bottom, and prevent partially melted water from remaining attached to the side and bottom of the detection drawer 100.

[0044] Example 3

[0045] On the basis of Example 2, Figure 2 and Fig. 9 As shown, it also includes an annular magnet 301 and an electromagnet strip 302 ; the annular magnet 301 is arranged in the detection drawer 100 ; the electromagnet strip 302 is fixedly connected in the groove of the box body 4 .

[0046] The box body 4 is fixedly connected with the baffle plate 303 , and the baffle plate 303 is located on the upper side of the electromagnet bar 302 , and the baffle plate 303 is flush with the inner wall of the box body 4 .

[0047] When the refrigerator drawer is actually used, a large amount of food is often placed inside it, making the overall weight of the drawer heavier, resulting in greater friction during the pulling process. In addition, it is often filled with hard food such as ribs that need to be frozen. During the pulling process, the frozen ribs are easily collided with the drawer under the action of inertia, causing damage to the drawer during use. Therefore, when the detection drawer 100 is manually placed between the box body 4 and the partition 5, the annular magnet 301 is placed in the detection drawer 100 at the same time, such as Fig. 9 As shown, by placing the annular magnet 301 in the detection drawer 100 to increase the overall weight of the detection drawer 100, the friction between the detection drawer 100 and the ice cubes is increased, thereby ensuring the authenticity of the drawer pull-out detection; and when the telescopic cylinder 2 drives the detection drawer 100 to be pulled out repeatedly, the annular magnet 301 in the detection drawer 100 collides with the detection drawer 100 under the action of inertia, so as to simulate the situation in which harder ingredients such as ribs will collide with the drawer when the refrigerator drawer is actually pulled out and used, thereby improving the reliability of the drawer pull-out detection result; and when placing ingredients in the refrigerator drawer, the position of the ingredients in the drawer is uncertain, and ingredients in different positions collide with the detection drawer 100 with different forces under the action of inertia, so the annular magnet 301 is directly It is placed in the detection drawer 100 for detection, and its placement position is fixed, which makes its simulation detection have certain limitations. Therefore, during the pulling process, one of the electromagnet bars 302 can be controlled separately to be powered on. The electromagnet bar 302 is powered on to magnetically attract the annular magnet 301, so that the annular magnet 301 moves in the detection drawer 100, and then changes the position of the annular magnet 301 in the detection drawer 100, so as to simulate the collision between food in different positions and the detection drawer 100, improve the authenticity of the simulation, and thus improve the reliability of the refrigerator drawer performance detection; and, a baffle 303 is provided on the upper side of the electromagnet bar 302, which can shield and protect the electromagnet bar 302 to prevent the electromagnet bar 302 from being damaged during the pulling process.
