[0019] The adjustment assembly includes a direct drive motor 201, a hinge joint 202 and a first electric push rod 203; the direct drive motor 201 is fixedly connected to the front side of the detector 1; the output end of the direct drive motor 201 is fixedly connected to the hinge joint 202; a micro motor is installed on the hinge joint 202, and the hinge joint 202 is rotated by the micro motor; the other end of the hinge joint 202 is fixedly connected to the first electric push rod 203; the telescopic end of the first electric push rod 203 is fixedly connected to the fixing plate 2.

[0020] It further includes a support plate 3; four support plates 3 arranged in a ring are installed on the fixing plate 2; the support plate 3 is set to be curved; a covering cloth 3001 is provided between adjacent two support plates 3; a shielding cover is jointly formed among all the support plates 3 and the covering cloth 3001.

[0021] It further includes a second electric push rod 204; the support plate 3 is set to be rotatably connected to the fixing plate 2; a second electric push rod 204 is connected between each support plate 3 and the fixing plate 2 through a hinge.

[0022] Furthermore, the covering cloth 3001 is made of an elastic material.

[0023] Furthermore, to prevent the decorative ball from being deformed under pressure when clamped by the support plate 3, the inner surface of the support plate 3 is covered with a flexible rubber layer.

[0024] Furthermore, to prevent the sequins on the decorative ball from being sucked into the detector 1 after detachment, a filter screen is provided at the exhaust hole 2002.

[0025] The following describes in detail the process of detecting the installation firmness performance of decorative balls during the mass production of Christmas trees: First, the detector operator holds the detector 1 and moves it in front of the Christmas tree, and randomly selects several decorative balls on the Christmas tree to be detected for detecting the installation firmness of the decorative balls. Here, it should be noted that the decorative balls are fixed by pasting them on the Christmas tree with glue. By adjusting the position of the detector 1 by the operator, the fixing plate 2 is oriented towards the decorative ball to be detected. Since the sizes of Christmas trees vary, when the Christmas tree is taller than the detector operator, it is inconvenient for the operator to detect the decorative balls at higher positions. Therefore, by controlling the telescopic end of the first electric push rod 203 to extend, with the view from right to left as the reference, the hinge joint 202 is driven by the micro motor on the hinge joint 202 to rotate clockwise. At the same time, with the view from front to back as the reference, the hinge joint 202 and its connecting parts are driven by the direct drive motor 201 to rotate. In this way, the fixing plate 2 can move in the front-back, up-down, and left-right directions. Thus, through the coordinated movement of the direct drive motor 201, the hinge joint 202, and the first electric push rod 203, the fixing plate 2 is oriented towards the decorative balls at higher or lower positions, so that the operator can conveniently detect the decorative balls at the top or bottom of the Christmas tree without climbing or bending down, improving the convenience of the operator for detecting the decorative balls. When the fixing plate 2 is oriented towards the decorative ball, air is supplied into the air inlet hole 1001 through an external air supply device. Subsequently, the air passes through the connecting pipe 4 and enters the cavity 2001, and finally exits from the exhaust hole 2002, so that the air continuously blows towards the rear half side of the decorative ball to be detected. Since the decorative ball is light in weight, when the air blows towards the decorative ball, the decorative ball will shake, thus simulating the situation where the decorative ball is blown by the airflow in the environment. At this time, the operator observes whether the decorative ball detaches from the Christmas tree under the blowing of the air, so as to detect the wind resistance performance of the decorative ball on the Christmas tree.

[0026] On this basis, since the temperature in the environment will affect the viscosity of the glue, thus affecting the connection firmness between the decorative ball and the Christmas tree, and the conventional detection methods usually do not consider the influence of temperature, resulting in a decrease in the accuracy of the detection results of the decorative balls. Therefore, when blowing air towards the decorative ball, the temperature of the blown air can be controlled by the external air supply device to lower the temperature of the air blown towards the detection ball, so as to simulate the low-temperature environment outdoors and thus detect the installation firmness between the decorative ball and the Christmas tree in the low-temperature environment.

[0027] Further, when air is blown from the exhaust hole 2002 towards the decorative ball, a part of the air disperses in all directions after being blown out from the exhaust hole 2002. In this way, part of the air volume blown towards the decorative ball is lost, reducing the detection energy efficiency ratio. Therefore, when the fixing plate 2 approaches the decorative ball, the support plate 3 and the cover cloth 3001 are synchronously driven to approach the decorative ball, so that the shield jointly formed between the support plate 3 and the cover cloth 3001 covers the periphery of the decorative ball. In this way, the dispersed air flow is converged by the shield, making the air blown towards the decorative ball more concentrated, reducing the air volume loss, and thus improving the detection energy efficiency ratio.

[0028] Since the sizes of the decorative balls are different, in order to adapt to the detection of larger decorative balls, therefore, when the shield is in the initial state, the telescopic end of the second electric push rod 204 is in the stretched state. When the size of the shield is smaller than that of the decorative ball, here, the second electric push rod 204 located at the uppermost side is taken as an example for detailed description. By controlling the telescopic end of the second electric push rod 204 to retract, with the view from right to left as the reference, the support plate 3 located at the uppermost side rotates upward, so that the support plate 3 at the uppermost side moves away from the decorative ball. At the same time, the remaining three support plates 3 also move away from the decorative ball. At the same time, since the cover cloth 3001 is set to be made of an elastic material, the cover cloth 3001 between two adjacent support plates 3 starts to stretch, so that the four rotated support plates 3 and the adjacent cover cloth 3001 form a shield with a larger size until the size of the shield is larger than that of the decorative ball. At this time, control the telescopic end of the second electric push rod 204 to stop retracting, so that it is convenient to cover the shield around the decorative ball and improve the adaptability of the shield to decorative balls of different sizes.

[0029] Furthermore, during the display of the Christmas tree, the decorative balls may shake due to the influence of external air currents or may be pulled by hand. Compared with the continuous blowing of the wind, the time of pulling by hand is usually shorter, but the applied force is greater. Therefore, in order to ensure the safety and stability of the decorative balls, it is very necessary to conduct a special pulling test, which can simulate the artificial pulling situation that may be encountered in actual display, so as to test the installation reliability of the decorative balls. For this purpose, when the wind resistance performance test of the decorative ball is completed, at this time, the peripheral air supply device is controlled to suck air reversely, so that the air near the fixed plate 2 enters the cavity 2001 through the exhaust hole 2002, and then the air is transported back to the peripheral air supply device through the connecting pipe 4. In this way, a negative pressure is formed in the shield, so as to suck the decorative ball through the negative pressure. At the same time, by controlling the retraction of the telescopic end of the first electric push rod 203, the fixed plate 2, the support plate 3 and the decorative ball are driven to move backward, so that the decorative ball is subjected to a backward pulling force, so as to simulate the situation when the decorative ball is pulled by an external force, so as to detect the installation firmness performance of the decorative ball when it is pulled by an external force, make the detection conditions diversified, and make the detection results more in line with the actual use situation. On this basis, before the pulling test of the decorative ball, the telescopic end of the second electric push rod 204 can be controlled to extend, so that the four support plates 3 all approach the decorative ball side until the inner sides of the four support plates 3 are attached to the decorative ball, and at the same time, the cover cloth 3001 is adaptively covered on the surface of the decorative ball. In this way, the support plate 3 and the cover cloth 3001 pre-clamp the decorative ball, so that the pulling test of the decorative ball can be carried out in cooperation with the negative pressure in the shield, so that the decorative ball is evenly stressed in the pulling test. Compared with the conventional detection method, by changing the flow direction of the air flow at the exhaust hole 2002, the wind resistance performance test and the pulling test of the decorative ball can be realized, without setting up an additional clamping jaw mechanism, the structure is simple, the production cost of the equipment and the subsequent maintenance cost are reduced, and the use is more convenient. It should be noted here that the inner surface of the support plate 3 is covered with a flexible rubber layer. When the support plate 3 pre-clamps the decorative ball, the flexible rubber layer reduces the extrusion of the support plate 3 on the decorative ball, avoiding the deformation of the decorative ball.

[0030] On this basis, since flash pieces are usually pasted on the surface of the decorative ball, when the pulling test of the decorative ball is carried out, some flash pieces are separated due to the suction of the air flow, so it is easy to enter the detector 1 through the exhaust hole 2002, so that the flash pieces are accumulated inside the detector 1, which is difficult to clean and easy to damage the equipment. For this reason, a filter screen is arranged on the exhaust hole 2002, so that the flash pieces in the air are intercepted outside the exhaust hole 2002 by the filter screen, so as to avoid the accumulation of flash pieces inside the detector 1 and extend the service life of the equipment. When more flash pieces are intercepted on the surface of the filter screen, only need to control the air flow to blow from the exhaust hole 2002 to the filter screen, so that the flash pieces on the filter screen can be blown out of the shield, realizing the cleaning of the filter screen.

[0031] Embodiment 2 Based on Embodiment 1, as Figure 1 and Figure 5 shown, it further includes an arc-shaped plate 301; an arc-shaped plate 301 is fixedly connected to the front side of each support plate 3; all the arc-shaped plates 301 are arranged in a ring; each arc-shaped plate 301 is bent towards the center side of the ring.

[0032] It further includes a connecting cloth 302; the connecting cloth 302 is fixedly connected between two adjacent arc-shaped plates 301; each connecting cloth 302 is connected to the adjacent cover cloth 3001.

[0033] Furthermore, the connecting cloth 302 is made of an elastic material.

[0034] When detecting the installation firmness performance of the decorative ball in a low-temperature environment, due to the obstruction of the decorative ball, air can only blow to the rear half side of the decorative ball, while the connection part between the decorative ball and the Christmas tree is located at the front half side of the decorative ball. In this way, it is difficult for air to blow to the front half side of the decorative ball. Therefore, it takes a long time for the connection part between the decorative ball and the Christmas tree to be reduced to the required low-temperature state, reducing the detection efficiency. For this reason, by arranging the arc-shaped plate 301 on the front side of the support plate 3, at this time, the bent side of each arc-shaped plate 301 faces the front end of the decorative ball. When the low-temperature air flow blows to the front side of the support plate 3 along the baffle, the arc-shaped plate 301 guides the low-temperature air flow to blow to the front end of the decorative ball, thereby specifically cooling the connection part between the decorative ball and the Christmas tree, enabling it to reach the low-temperature detection requirement faster and improving the detection efficiency. On this basis, all the arc-shaped plates 301 are united into a whole through four connecting cloths 302, and form a whole with the baffle formed between the support plate 3 and the cover cloth 3001, further improving the effect of the baffle in converging the air flow, reducing the air volume loss, and improving the detection energy efficiency ratio. Here it is explained that since the connecting cloth 302 is made of an elastic material, when the support plate 3 drives the arc-shaped plate 301 away from the decorative ball, the connecting cloth 302 between two adjacent arc-shaped plates 301 is adaptively stretched, so that it is convenient for decorative balls of different sizes to pass through the arc-shaped plate 301 and the connecting cloth 302.

[0035] On this basis, when the connection between the decorative ball and the Christmas tree is not firm, during the process of pulling test on the decorative ball, the situation where the decorative ball detaches from the Christmas tree will occur. In this way, the decorative ball is likely to slide from within the support plate 3 to the ground. Since the spherical decorative ball is easy to roll around, it will hide in the gaps at the bottom of various devices in the detection area. This is not conducive to the recovery and cleaning of the decorative ball. For this reason, when conducting the pulling test, the support plate 3 first contacts the decorative ball to complete pre-clamping. At this time, the four arc-shaped plates 301 cover the front half side of the decorative ball. When the decorative ball detaches from the Christmas tree, the arc-shaped plate 301 blocks the decorative ball from sliding out of the support plate 3, thereby preventing the decorative ball from rolling around, so that it is convenient for the tester to quickly recover the detached decorative ball.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
