Abstract
Description
Technical Field
[0001] This disclosure relates to the field of testing equipment technology, and in particular to a drop detection device. Background Technology
[0002] In drop testing of products, it is usually necessary to simulate the drop of the product's edges, corners, and surfaces from different heights to further improve and refine the product design. Existing drop testing equipment requires manual fixation of the product and adjustment of its drop posture before a winch is used to lift the product to a certain height and release it, allowing it to fall freely to the ground to complete the drop test. Since the mass distribution of most products is non-uniform, the product's center of gravity does not coincide with its geometric center. This offset makes it difficult for drop testing to meet the requirement in national standard GB-T4857.5-1992 that the gravity line of the test sample should pass through the edge or corner being dropped. Furthermore, manually adjusting the drop posture results in insufficient accuracy to meet the testing standards, leading to unstable testing, time-consuming and labor-intensive processes, and reduced testing efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.
[0047] The embodiments of this utility model are described below with reference to the accompanying drawings.
[0048] For ease of explanation, in Figure 1A three-dimensional coordinate system is added. The Z-axis is the first direction, which is the direction in which the first drive component 12 drives the second drive component 13. The Y-axis is the second direction, which is the direction in which the second drive component 13 drives the adjustment component 141. The X-axis is the third direction, which is the setting direction of the two columns 1211. The first direction is the direction of gravity, and the first, second, and third directions are perpendicular to each other.
[0049] Please see Figure 1 This disclosure provides a drop detection device, which includes a support component 11, a first drive component 12, and a posture adjustment mechanism 14. The first drive component 12 is connected to the support component 11, and a second drive component 13 is connected to the first drive component 12. The first drive component 12 is used to drive the second drive component 13 to move along a first direction. The posture adjustment mechanism 14 includes an adjustment component 141 and a suction component 142. The adjustment component 141 is provided with a first axis 1414. The adjustment component 141 is connected to the second drive component 13 and the suction component 142. The second drive component 13 is used to drive the adjustment component 141 to move along a second direction perpendicular to the first direction. The suction component 142 is used to pick up a product 20. The adjustment component 141 is used to drive the suction component 142 to rotate the picked-up product 20 around the first axis 1414 to adjust the drop angle of the product 20.
[0050] For example, the product to be tested 20 can be the packaging box of the electronic product 20. During the test, the packaging box can be tested directly as an empty box, or after packaging the electronic product 20, or after packaging a model of the electronic product 20.
[0051] In the aforementioned drop detection device, firstly, the suction component 142 picks up the product 20 to be tested, and the first drive component 12 drives the second drive component 13 to move the adjustment component 141, the suction component 142, and the picked-up product 20 along a first direction to adjust the drop height of the product 20. Then, the second drive component 13 drives the adjustment component 141 to move the suction component 142 and the picked-up product 20 along a second direction to adjust the drop position of the product 20. Finally, the adjustment component 141 drives the suction component 142 to rotate the picked-up product 20 around the first axis 1414 to adjust the drop angle of the product 20, thereby achieving... The drop posture of product 20 is adjusted; thus, product 20 is directly adsorbed and grasped by the adsorption component, eliminating the need for manual loading, thereby reducing labor intensity, saving time and effort, and improving detection efficiency. At the same time, the adjustment component 141 drives the suction component 142 and the product 20 being picked up to rotate around the fixed first axis 1414, so that the first axis 1414 can be used as the reference standard for adjusting the angle of the suction component 142 and the product 20 being picked up, thereby making the adjustment accuracy of the drop angle of the suction component 142 and the product 20 being picked up higher, and thus improving the stability of detection. Therefore, the drop detection device improves the stability of detection while improving detection efficiency.
[0052] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the adjusting component 141 includes a movable member 1411, a connecting member 1412, and a telescopic member 1413. The movable member 1411 is connected to the second driving component 132, which drives the movable member 1411 to move along a second direction. One end of the connecting member 1412 is connected to the movable member 1411, and the other end is rotatably connected to the suction member 142. The other end of the connecting member 1412 is provided with a first axis 1414. Specifically, the connecting member 1412 is a connecting rod. One end of the telescopic member 1413 is rotatably connected to the suction member 142, and the other end is rotatably connected to the connecting member 1412. When the telescopic member 1413 extends or retracts, it drives the suction member 142 to rotate around the first axis 1414. For example, the extension direction of the first axis 1414 can be either the second direction or a third direction.
[0053] Thus, the telescopic component 1413 drives the suction component 142 to rotate around the other end of the connector 1412 through its own telescopic movement, thereby adjusting the tilt angle of the suction component 142 and realizing the release angle of the suction component 142 and the adsorbed product 20. The tilt angle of the suction component 142 can be calculated based on the telescopic length of the telescopic component 1413 to improve the adjustment accuracy. At the same time, the adjustment component 141 has a simple structure and fast adjustment speed.
[0054] This application does not limit the structure of the telescopic member 1413. For example, the telescopic member 1413 can be a hydraulic telescopic rod, a pneumatic telescopic rod, or an electric telescopic rod.
[0055] Furthermore, the number of telescopic members 1413 can be multiple, and the multiple telescopic members 1413 are arranged at intervals along the second direction. Specifically, the number of telescopic members 1413 is two or three.
[0056] Please refer to Figure 3 In some embodiments, one end of the connector 1412 is rotatably connected to and passes through the movable member 1411. Specifically, the rotational relationship between one end of the connector 1412 and the movable member 1411 is that the connector 1412 rotates around its own center line. The posture adjustment mechanism 14 also includes a rotation drive member 143. The connector 1412 is also provided with a second axis 1415 perpendicular to the first axis 1414. Specifically, the connector 1412 is a connecting rod, and correspondingly, the second axis 1415 is the center line of the connecting rod, and the extension direction of the second axis 1415 is the first direction. The rotation drive member 143 is connected to the movable member 1411 and one end of the connector 1412 and is used to drive the connector 1412 to rotate around the second axis 1415.
[0057] Thus, the connecting member 1412 is driven to rotate around its own center line (i.e., the second axis 1415) by the rotary drive member 143. The connecting member 1412 drives the suction member 142 and the adsorbed product 20 to rotate around the second axis 1415, so as to adjust the angle of the suction member 142 in the horizontal direction, thereby adjusting the angle of the suction member 142 when gripping and releasing the product 20.
[0058] Please refer to Figure 3 Furthermore, the rotary drive 143 includes a driven gear 1431, a driving gear 1432, and a rotary motor 1433. The driven gear 1431 is connected to one end of the connector 1412. The rotary drive 143 is connected to the driving gear 1432 and the movable part 1411. The driving gear 1432 meshes with the driven gear 1431. The rotary drive 143 drives the driving gear 1432 to rotate the driven gear 1431, and through the driven gear 1431, drives the connector 1412 to rotate around the first axis 1414.
[0059] Please refer to Figure 3 In some embodiments, the suction element 142 includes a suction disk 1421 and a negative pressure source 1422. The suction element 142 is connected to the adjustment assembly 141 and is used to adsorb the product 20. The negative pressure source 1422 is connected to the suction disk 1421 and is used to provide negative pressure to the suction disk 1421. For example, the negative pressure source 1422 can be a negative pressure pump or a vacuum pump.
[0060] Further, a plurality of suction heads are embedded in the adsorption surface of the suction cup. The plurality of suction heads are evenly arranged and connected to the negative pressure source 1422 through air pipes. The plurality of suction heads can improve the adsorption stability and have better firmness when adsorbing and fixing the product 20.
[0061] Please refer to Figure 1 , in some embodiments, the first driving component 12 includes a first driving bracket 121, a lead screw 122, a lifting member 123 and a first driving member 124. The first driving bracket 121 is connected to the carrying component 11. The lead screw 122 extends along the first direction, and one end of the lead screw 122 is rotatably connected to the carrying component 11, and the other end of the lead screw 122 is rotatably connected to the first driving bracket 121. The lifting member 123 is connected to the second driving component 13 and is threadedly connected to the lead screw 122. The first driving member 124 is connected to the first driving bracket 121 and is connected to one end of the lead screw 122. The first driving member 124 is used to drive the lead screw 122 to rotate, so that the lead screw 122 drives the lifting member 123 to move along the first direction. Exemplarily, the first driving member 124 can be a motor.
[0062] In this way, the first driving member 124 drives the lead screw 122 to rotate. The lead screw 122带动升降件123在第一方向上移动,并带动第二驱动组件13沿第一方向运动,以便于调节姿势调节机构14在第一方向的位置,从而调节姿势调节机构14的跌落检测的高度。
[0063] Please refer to Figure 1 , in some embodiments, the first driving bracket 121 includes two columns 1211 and a connecting frame 1212. The two columns 1211 are arranged at intervals along the third direction, and one end of each column 1211 is connected to the carrying component 11. Each column 1211 extends along the first direction. The lead screw 122 is arranged between the two columns 1211. The two ends of the connecting frame 1212 in the third direction are respectively connected to the other ends of the two columns 1211, and the other end of the lead screw 122 is rotatably passed through the connecting frame 1212. The first driving member 124 is connected to the connecting frame 1212 and the other end of the lead screw 122.
[0064] In this way, the two columns 1211 and the connecting frame 1212 form a stable "冂"-shaped structure, and the lead screw 122 is arranged between the two columns 1211, so as to support the stable rotation of the lead screw 122 and have a simple structure.
[0065] Please refer to Figure 2 It should be noted that there is an unclear part in the original text of line where the description of "带动升降件123在第一方向上移动" is incomplete. The above translation is based on the existing content as accurately as possible.In some embodiments, the second drive assembly 13 includes two sliding sleeves 131 and a second drive member 132. Each sliding sleeve 131 is slidably fitted onto a corresponding column 1211 and connected to the lifting member 123. The second drive member 132 is connected to the two sliding sleeves 131 and the movable member 1411, and is used to drive the movable member 1411 to move along a second direction. For example, the second drive member 132 can be an electric slide rail or an electric slide table.
[0066] Thus, when the first drive assembly 12 drives the lifting member 123 to move in the first direction, the lifting member 123 drives the two sliding sleeves 131 to move in the first direction, and the two sliding sleeves 131 are guided by the column 1211 extending along the first direction to improve the stability when moving in the first direction. The second drive assembly 132 drives the posture adjustment mechanism 14 to move in the second direction to adjust the position of the posture adjustment mechanism 14 in the second direction.
[0067] Furthermore, there are two second driving members 132, which are spaced apart along a third direction.
[0068] One end of each second drive member 132 is connected to a corresponding sliding sleeve 131, and a fixing plate 133 is connected between the other ends of the two second drive members 132.
[0069] Please refer to Figure 1 In some embodiments, the support component 11 includes a base 111 and a punching plate 112. The base 111 is connected to the first drive component 12 and spaced apart from the second drive component 13 along a first direction. The punching plate 112 is detachably connected to the side of the base 111 facing the second drive component 13 and is used to receive the product 20 released by the suction component 142.
[0070] In this way, the impact plate 112 can withstand the impact force of the product 20 falling, avoiding the base 111 from being directly damaged by the impact force. Furthermore, by designing the impact plate 112 as a detachable structure, it can be used as a consumable. When the impact plate 112 is damaged due to long-term impact, it can be replaced, thereby reducing the maintenance cost of the load-bearing component 11.
[0071] This application does not limit the detachable connection method between the impact plate 112 and the base 111. For example, the impact plate 112 and the base 111 can be connected by bolts or by snap-fit.
[0072] Please refer to Figure 1In some embodiments, the support component 11 further includes a plurality of wheels 113, which are mounted on the side of the base 111 away from the impact plate 112. In this way, the base 111 is supported by the plurality of wheels 113, and the drop detection device can be moved to any position by the wheels 113, which saves time and effort and is easy to operate.
[0073] Specifically, the number of traveling wheels 113 can be four, six or eight, and the multiple traveling wheels 113 are evenly distributed on the side of the base 111 away from the impact plate 112, so as to provide stable support for the base 111.
[0074] This application does not limit the structure of the traveling wheel 113. For example, the traveling wheel 113 can be a swivel wheel, a brake wheel, or a swivel brake wheel.
[0075] Please refer to Figure 1 In some embodiments, the first drive bracket 121 is also provided with a scale line 125 for observing the lifting height of the second drive component 13; thus, the height of the second drive component 13, the adjustment component 141, the suction component 142, and the product 20 to be tested adsorbed by the suction component 142 can be directly observed through the scale line 125.
[0076] The working principle of the drop detection device described above is roughly as follows:
[0077] First, the second drive component 13 drives the adjustment component 141 to move the suction component 142 along the second direction to directly above the product 20 to be tested;
[0078] Then, the rotating drive 143 drives the connector 1412 to rotate the suction member 142 around the second axis 1415 to adjust the angle at which the suction member 142 adsorbs the product 20 to be tested, thereby adjusting the position of the product 20 to be tested when it is impacted by the impact plate.
[0079] Next, the first driving component 12 drives the second driving component 13 to move the adsorption element down to the upper surface of the product to be tested 20, and the adsorption element adsorbs and fixes the product to be tested 20.
[0080] Finally, the telescopic movement of the telescopic component 1413 causes the adsorption component and the adsorbed product 20 to rotate around the first axis 1414, thereby adjusting the drop angle of the adsorption component 142 and the adsorbed product 20. The second drive component 13 drives the adjustment component 141 to move the adsorption component 142 along the second direction to directly above the impact plate 112, and the product 20 is released by the adsorption component 142 to achieve the drop test of the product 20.
[0081] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
