[0006] Preferably, it also includes an electric push rod III and a fireproof cloth; a number of electric push rods III are fixedly connected to the round rod; each electric push rod III has a fireproof cloth connected to its telescopic end, and the fireproof cloth is connected to the corresponding round rod.

[0007] Preferably, the electric push rod III is detachably connected to the fireproof cloth, and the fireproof cloth is detachably connected to the round rod.

[0008] As a preferred embodiment, it also includes a camera I, a connecting rod, a hammer ball, an electric push rod I, an electric turntable, and a hydraulic rod; the housing is fixedly connected to the electric push rod I; the telescopic end of the electric push rod I is rotatably connected to the electric turntable; the electric turntable is fixedly connected to the connecting rod; the telescopic end of the hydraulic rod is fixedly connected to the connecting rod, and the hammer ball is fixedly connected to the telescopic end of the hydraulic rod.

[0009] Preferably, the camera II is fitted with a transparent glass protective cover.

[0010] Preferably, the drive assembly includes an electric guide rail I, a moving block I, an electric guide rail II, and a moving block II; the housing is fixedly connected to the electric guide rail I; the electric guide rail I is slidably connected to the moving block I; the moving block I is fixedly connected to the electric guide rail II; the electric guide rail II is slidably connected to the moving block II, and the moving block II is fixedly connected to one of the cameras II, and the moving block II is fixedly connected to one of the motors III.

[0014] The present invention has the following advantages: The present invention controls the arc-shaped guide rail to make the electric slider I drive the connecting plate, motor II and clamp II to slowly bend the plastic part body.

[0015] Before the nozzle sprays flames onto the plastic part for flame retardancy testing, two electric push rods III are controlled to move the corresponding fireproof cloths closer to the surface of the plastic part. This causes the electric push rods III to pull the corresponding fireproof cloths until they contact the surface of the plastic part. In this way, the two fireproof cloths isolate the flame spray area of ​​the nozzle, preventing other areas of the plastic part from catching fire.

[0016] By controlling the electric turntable to drive the connecting rod to rotate, the hammer ball is directed towards the lower side of the plastic part. Then, the hydraulic rod is controlled to move the hammer ball downward, causing the hammer ball to rapidly hammer the plastic part, creating a dent in the plastic part. The plastic part is then bent to test its bending resistance with the dent present. Simultaneously, the impact resistance of the plastic part is tested using camera I. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0028] Example 1: A quality inspection machine for automotive plastic parts production, as shown in Figures 1-9, includes a housing 1 and a door 2; the housing 1 is rotatably connected to the door 2.

[0029] It also includes a clamp I 101, a motor I 102, an arc-shaped guide rail 103, an electric slider I 1031, a connecting plate 104, a motor II 105, a clamp II 106, a detection component, and a drive component; the clamp I 101 is rotatably connected to the housing 1; two motors I 102 are fixedly connected to the housing 1; the arc-shaped guide rail 103 is bolted to the housing 1; the electric slider I 1031 is slidably connected to the arc-shaped guide rail 103; the electric slider I 1031 is rotatably connected to the connecting plate 104; the motor II 105 is bolted to the connecting plate 104; the output shaft of the motor II 105 is fixedly connected to the clamp II 106; the housing 1 is connected to a drive component for moving the detection component; the drive component is connected to a detection component for detecting the plastic part body 3.

[0030] The detection assembly includes an electric push rod II 201, a cover plate 202, an electric slider II 203, a camera II 204, a motor III 205, a round rod 206, a nozzle 207, an oil supply pipe 208, and a motor IV 2015. The housing 1 is bolted to the electric push rod II 201. The telescopic end of the electric push rod II 201 is fixedly connected to the motor IV 2015, and the output shaft of the motor IV 2015 is connected to a cover plate 202. The cover plate 202 has a sliding groove 21. The electric slider II 203 is slidably connected within the sliding groove 21. The electric slider II 203 is fixedly connected to the camera II 204. Another camera II 204 is connected to the drive assembly. The electric slider II 203 is bolted to the motor III 205. Another motor III 205 is connected to the drive assembly. Each output shaft of each motor III 205 is fixedly connected to a round rod 206. Each round rod 206 is fixedly connected to a nozzle 207. Each round rod 206 is fixedly connected to an oil supply pipe 208.

[0031] It also includes an electric push rod Ⅲ2010 and a fireproof cloth 2012; two electric push rods Ⅲ2010 are fixedly connected to the round rod 206; each electric push rod Ⅲ2010 has a fireproof cloth 2012 connected to its telescopic end, and the fireproof cloth 2012 is connected to the corresponding round rod 206.

[0032] The electric push rod Ⅲ2010 is detachably connected to the fireproof cloth 2012, and the fireproof cloth 2012 is detachably connected to the round rod 206. Since the fireproof cloth 2012 is burned by flames for a long time during the flame isolation process, its fireproof performance will gradually decrease. Therefore, it is necessary to regularly remove the fireproof cloth 2012 from the electric push rod Ⅲ2010 and the round rod 206 for replacement to ensure the fireproof effect of the fireproof cloth 2012.

[0033] It also includes a camera I 107, a connecting rod 109, a hammer ball 1011, an electric push rod I 1017, an electric turntable 1018, and a hydraulic rod 1019; the housing 1 is bolted to the electric push rod I 1017; the telescopic end of the electric push rod I 1017 is rotatably connected to the electric turntable 1018; the electric turntable 1018 is fixedly connected to the connecting rod 109; the telescopic end of the hydraulic rod 1019 is fixedly connected to the hammer ball 1011.

[0034] The camera II 204 is equipped with a transparent glass protective cover. When performing flame retardant testing on the plastic body 3 in a bent state, the transparent glass protective cover protects against splashing molten droplets, preventing high-temperature molten droplets from directly splashing onto the camera II 204 and making subsequent cleaning difficult.

[0035] The drive assembly includes an electric guide rail I1013, a moving block I1014, an electric guide rail II1015, and a moving block II1016; the housing 1 is bolted to the electric guide rail I1013; the electric guide rail I1013 is slidably connected to the moving block I1014; the moving block I1014 is fixedly connected to the electric guide rail II1015; the electric guide rail II1015 is slidably connected to the moving block II1016, and the moving block II1016 is fixedly connected to one of the cameras II204, and the moving block II1016 is fixedly connected to one of the motors III205.

[0036] The transparent door 2 allows operators to observe the inspection status of the plastic parts 3 inside the box 1, and thus make timely adjustments to the inspection work.

[0037] Using the view directly facing Figure 1 as a reference, first connect the external oil pump to the oil supply pipe 208. When in use, the operator opens the box door 2, fixes one horizontal end of the plastic part body 3 to be tested on the clamp I 101, and fixes the other end of the plastic part body 3 on the clamp II 106. The initial state is shown in Figure 2. Then, close the box door 2.

[0038] Next, the motor Ⅲ 205 on the electric slider Ⅱ 203 is controlled to drive the round rod 206 to rotate so that the nozzle 207 is directed toward the upper side of the plastic body 3. Then, the nozzle 207 is controlled to spray flames toward the upper side of the plastic body 3. After burning for ten seconds, the camera Ⅱ 204 observes the extinguishing time of the flame on the plastic body 3 to detect the flame retardant performance of the plastic body 3 in a horizontal state.

[0039] Next, the control motor II 105 is started, and the output shaft of the motor II 105 drives the clamp II 106 to rotate, so that the clamp II 106 twists one end of the plastic part body 3, as shown in Figure 4. The twisting of the plastic part body 3 is observed by the camera II 204, thereby detecting the anti-torsion performance of the plastic part body 3. After the plastic part body 3 is twisted, the control nozzle 207 sprays flames onto the upper side of the plastic part body 3, thereby detecting the flame retardant performance of the plastic part body 3 under the twisting state, improving the comprehensiveness of the detection.

[0040] Next, the output shaft of motor II 105 drives clamp II 106 to rotate, causing the plastic body 3 to return to a horizontal state under its own elastic force. Then, the arc-shaped guide rail 103 controls the electric slider I 1031 to drive the connecting plate 104, motor II 105 and clamp II 106 to slowly bend the plastic body 3 into the bent shape shown in Figure 5. The bending condition of the plastic body 3 is observed through camera II 204 to detect the bending performance of the plastic body 3. Considering that after the plastic body 3 is bent, the outer side of the plastic body 3 is prone to micro-cracks due to stretching, while the inner side of the plastic body 3 is compressed, it is necessary to detect whether the flame retardant properties of the inner and outer sides of the plastic body 3 have changed. At this time, the nozzle 207 on the moving block II 1016 sprays flames onto the outer side of the bent plastic body 3. Subsequently, the nozzle 207 on the electric slider II 203 sprays flames onto the inner side of the bent plastic body 3 to detect the difference in flame retardant properties between the inner and outer sides of the plastic body 3 under the bending state, thereby improving the comprehensiveness of the detection.

[0041] Considering that the plastic body 3 in the car will come into contact with various fluids in the car, such as gasoline, engine oil, and antifreeze, it is necessary to test the flame retardant performance of the plastic body 3 after bending and deformation with fluid adhering to its surface. This is to simulate the flame retardant situation after the plastic products inside the car come into contact with fluid due to bending and deformation caused by a collision. Therefore, when the plastic body 3 is in a horizontal state, the external oil pump is first controlled to deliver fluid to the oil pipe 208, and then the oil pipe 208 sprays the fluid onto the upper surface of the horizontal plastic body 3. Subsequently, the arc-shaped guide rail 103 is controlled... The electric slider I 1031 is moved to bend the plastic part body 3. Then, the nozzle 207 on the electric slider II 203 sprays flames onto the inner side of the bent plastic part body 3. The effect of the oil on the flame retardant performance of the inner side of the plastic part body 3 is observed through the corresponding camera II 204. Subsequently, the nozzle 207 on the moving block II 1016 sprays flames onto the outer side of the bent plastic part body 3. The effect of the oil on the flame retardant performance of the outer side of the plastic part body 3 is observed through the corresponding camera II 204, making the test results closer to the actual use environment.

[0042] Because the oil used in automobiles is flammable, when the nozzle 207 sprays flames onto the inner and outer surfaces of the plastic body 3, other areas of the plastic body 3 are also easily ignited. Therefore, before the nozzle 207 sprays flames onto the plastic body 3 for flame retardancy testing, the two electric push rods III 2010 are controlled to move the corresponding fireproof cloth 2012 towards the surface of the plastic body 3. This causes the electric push rods III 2010 to pull the corresponding fireproof cloth 2012 until the fireproof cloth 2012 contacts the surface of the plastic body 3. In this way, the two fireproof cloths 2012 isolate the flame spray area of ​​the nozzle 207, preventing other areas of the plastic body 3 from catching fire.

[0043] Considering that cars may be dented by road debris during use, it is necessary to test the bending resistance of the plastic part body 3 when dented. The electric turntable 1018 is controlled to rotate the connecting rod 109, causing the hammer ball 1011 to face the lower side of the plastic part body 3. Then, the hydraulic rod 1019 is controlled to move the hammer ball 1011 downwards, causing it to rapidly hammer the plastic part body 3, creating a dent. The plastic part body 3 is then bent to test its bending resistance when dented. Simultaneously, the impact resistance of the plastic part body 3 is detected by the camera I 107. After testing one side of the plastic part body 3, the electric turntable 1018 rotates the connecting rod 109 180 degrees, causing the hammer ball 1011 to face the upper side of the plastic part body 3 for hammering testing on the other side.

[0044] Example 2, based on Example 1, as shown in Figures 2 and 7-8, fireproof cloth 2012 is sealed fireproof cotton.

[0045] It also includes hollow tube 2014; two hollow tubes 2014 are fixedly connected to the box body 1.

[0046] In this embodiment, the external pump is connected to the hollow tube 2014. In Embodiment 1, to prevent flames from escaping from the gap between the plastic part 3 and the fireproof cloth 2012 when the fireproof cloth 2012 is used to isolate the bent plastic part 3 from the flame, a sealing fireproof cotton is placed on the fireproof cloth 2012 to seal the gap between the plastic part 3 and the fireproof cloth 2012, thereby preventing flame escape. Furthermore, considering that the plastic part 3 in automobiles is used in various high and low temperature environments, the plastic part 3 softens and weakens at high temperatures and becomes brittle and prone to breakage at low temperatures. Therefore, when the plastic part 3 is in a straight state, the external pump is first controlled... The external pump delivers high-temperature gas into the housing 1 through the hollow tube 2014, placing the plastic part 3 in a high-temperature environment. First, the motor II 105 is controlled to make the plastic part 3 twist as shown in Figure 4. Then, the arc-shaped guide rail 103 drives the electric slider I 1031 to make the plastic part 3 bend as shown in Figure 5. The performance of the plastic part 3 in the high-temperature environment is tested. Next, the external pump delivers low-temperature gas into the housing 1 through the hollow tube 2014, placing the plastic part 3 in a low-temperature environment. First, the motor II 105 is controlled to make the plastic part 3 twist as shown in Figure 4. Then, the arc-shaped guide rail 103 drives the electric slider I 1031 to make the plastic part 3 bend as shown in Figure 5. The performance of the plastic part 3 in the low-temperature environment is tested.
