[0038] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] See also Figure 1 The product random drop test equipment of the utility model includes a product drop collection box 100, a CCD detection mechanism 200, a product grabbing mechanism 300, a hollow cavity 400 and a moving mechanism 500.

[0042] Among them, the product falling collection box 100 is used to collect the products after falling, prevent the products from exceeding the grabbing range of the product grabbing mechanism 300, and facilitate the product grabbing mechanism 300 to grab the products; the CCD detection mechanism 200 is used to detect the position of the products after falling, and transmit the detected position information to the product grabbing mechanism 300, so that the product grabbing mechanism 300 can accurately grab the products; the hollow cavity 400 interferes with the falling process of the product, so that the product produces a random and non-directional falling effect; the moving mechanism 500 is used to change the position of the hollow cavity 400. On the one hand, it can realize the interference effect of the hollow cavity 400 on the product falling, and on the other hand, it can also avoid the hollow cavity 400 from interfering with the operation of the product grabbing mechanism 300. In addition, the setting of the random falling space can be enriched by adjusting the different positions of the hollow cavity 400 relative to the top of the product falling collection box 100.

[0043] Specifically, the CCD detection mechanism 200 is located above the product drop collection box 100 , the product grabbing mechanism 300 is located on one side of the product drop collection box 100 , and the hollow cavity 400 is connected to the driving end of the moving mechanism 500 .

[0044] The moving mechanism 500 drives the hollow cavity 400 to be located above or on one side of the product drop collection box 100 , so that the product grabbing mechanism 300 drops the product through the hollow cavity 400 to the product drop collection box 100 or takes away the product in the product drop collection box 100 .

[0045] In the actual operation process, the product can be loaded through the material tray. After the product grabbing mechanism 300 grabs the product, it drives the product to move to the upper opening of the hollow cavity 400, and then drops the product. During the falling process, the product may hit the inner wall of the hollow cavity 400, causing interference, thereby changing the falling path of the product. The product finally falls into the product falling collection box 100 through the lower opening of the hollow cavity 400. Subsequently, the moving mechanism 500 drives the hollow cavity 400 to move to one side of the product falling collection box 100. To make way for the CCD detection mechanism 200, the CCD detection mechanism 200 detects the position of the product in the product drop collection box 100, and transmits the detected position information to the product grabbing mechanism 300, and the product grabbing mechanism 300 grabs the product in the product drop collection box 100 according to the position information, and then the moving mechanism 500 drives the hollow cavity 400 to move to the top of the product drop collection box 100, and the product grabbing mechanism 300 throws the product into the hollow cavity 400 again, and the cycle continues.

[0046] It should be noted that in the random drop test of the product, the product can be subjected to multiple random drop tests according to actual needs, such as 32 times or 50 times, etc. There is no specific limitation on this in this embodiment. After the product completes the last random drop test, the product grabbing mechanism 300 grabs the product from the product drop collection box 100 and unloads it.

[0047] In the random product drop test equipment provided in this embodiment, when the hollow cavity 400 is located above the product drop collection box 100, the product that finally falls into the product drop collection box 100 through the hollow cavity 400 can be limited and interfered by the hollow cavity 400 during the falling process, thereby producing a non-directional drop effect, thereby realizing a random drop test of a simulated product under natural use; the hollow cavity 400 can be moved to one side of the product drop collection box 100 under the action of the moving mechanism 500, so that the CCD detection mechanism 200 can detect the product position, so that the product grasping mechanism 300 can accurately grasp the product, and the entire process does not require manual operation, thereby realizing an automated operation effect and effectively reducing labor costs.

[0048] Embodiment 2:

[0049] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the hollow cavity 400 and the moving mechanism 500 of the utility model. Figure 2 .

[0050] Multiple connecting rods are arranged horizontally or diagonally inside the hollow cavity 400, or multiple connecting rods are arranged both horizontally and diagonally. The number and direction of the connecting rods are adjusted according to needs to ensure interference when the product falls, so that the path of the product falling each time is different, thereby simulating the falling situation in a natural state.

[0051] It can be understood that the hollow cavity 400 includes an upper opening and a lower opening, and when performing a random drop test, the lower opening of the hollow cavity 400 faces the product drop collection box 100 .

[0052] In one setting scheme, multiple connecting rods are horizontally arranged inside the hollow cavity 400, and the multiple connecting rods are respectively located at different heights of the hollow cavity 400, and the multiple connecting rods are staggered, so that when the product falls through the hollow cavity 400, it may be interfered by the connecting rods at different positions at different heights, thereby achieving a random and non-directional drop test effect.

[0053] Similarly, when multiple connecting rods are obliquely arranged inside the hollow cavity 400, the oblique setting angles of the multiple connecting rods are different, and the height settings are also different, so that when the product falls through the hollow cavity 400, it may be interfered by the different obliquely arranged connecting rods at different height positions, which better simulates the random and non-directional drop test scenario.

[0054] In some embodiments, the moving mechanism 500 includes at least a first driving module 510 and a second driving module 520 driven in different directions, the driving end of the first driving module 510 is connected to the second driving module 520, and the driving end of the second driving module 520 is connected to the hollow cavity 400, so as to achieve a displacement effect on the hollow cavity 400 and avoid interfering with the operation of the CCD detection mechanism 200 and the product grasping mechanism 300.

[0055] For example, the first driving module 510 is for horizontal driving, and the second driving module 520 is for lifting driving. When the product needs to be randomly dropped, the first driving module 510 can drive the hollow cavity 400 to move to the top of the product drop collection box 100. When the CCD detection mechanism 200 needs to detect the product position in the product drop collection box 100, the first driving module 510 drives the hollow cavity 400 to move to one side of the product drop collection box 100. When the height of the hollow cavity 400 needs to be adjusted, the second driving module 520 can be used to lift the hollow cavity 400 so that the interference effect caused by the hollow cavity 400 on the product falling process is different when the hollow cavity 400 is at different height positions.

[0056] Embodiment 3:

[0057] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the product grabbing mechanism 300 of the utility model. Figure 3 .

[0058] The product grabbing mechanism 300 includes a product grabbing robot 310 and a product grabbing module 320. The product grabbing module 320 is connected to the driving end of the product grabbing robot 310. The product grabbing module 320 moves to a set position under the driving action of the product grabbing robot 310 to grab or release the product, thereby achieving an automated operation effect.

[0059] Specifically, the product grasping module 320 includes a clamping unit 321 and a suction unit 322, both of which are connected to the driving end of the product grasping robot 310. The clamping unit 321 and the suction unit 322 are provided to meet the grasping of products in different placement states, and have the advantage of strong adaptability.

[0060] For example, when the product is incoming, the product is in a vertical position, so the clamping claw unit 321 can clamp the product; when the product falls into the product drop collection box 100, when the product is in a horizontal position, the suction unit 322 can suck the product.

[0061] Embodiment 4:

[0062] The difference between this embodiment and embodiment 1 is that the product random drop test equipment of this embodiment further includes a tray loading mechanism 600, a tray unloading mechanism 700 and a code scanning mechanism 800, Figure 4 and Figure 5 .

[0063] The product grabbing mechanism 300 is located between the tray loading mechanism 600 and the tray unloading mechanism 700, and uses the tray to load the product, and realizes the whole tray loading and unloading of the tray through the tray loading mechanism 600 and the tray unloading mechanism 700. The product grabbing mechanism 300 is arranged between the tray loading mechanism 600 and the tray unloading mechanism 700, so that the product grabbing mechanism 300 can grab the product at the position of the tray loading mechanism 600, and it is convenient to place the product that has completed the random drop test into the tray unloading mechanism 700.

[0064] In some embodiments, the tray unloading mechanism 700 includes a tray positioning platform 710 , a first positioning module 720 and a second positioning module 730 , and the first positioning module 720 and the second positioning module 730 are respectively located on two adjacent sides of the tray positioning platform 710 .

[0065] Among them, a first reference block 740 is arranged on the opposite side of the first positioning module 720, and a second reference block 750 is arranged on the opposite side of the second positioning module 730. The first positioning module 720 is used to drive the material tray to move toward the first reference block 740, and the second positioning module 730 is used to drive the material tray to move toward the second reference block 750. The material tray is driven and positioned in two different directions to accurately position the material tray, so as to accurately place the products that have completed the drop test in the material tray and achieve accurate operating results.

[0066] Specifically, the first positioning module 720 includes a first driving cylinder 721 and a first driving block 722. The first driving block 722 is connected to the driving end of the first driving cylinder 721. A roller 723 for contacting the material tray is provided on the side of the first driving block 722 away from the first driving cylinder 721. The positioning is driven by the rolling contact between the roller 723 and the periphery of the material tray, thereby achieving a better positioning effect and avoiding damage to the material tray.

[0067] Similarly, the second positioning module 730 includes a second driving cylinder and a second driving block. The second driving block is connected to the driving end of the second driving cylinder. A roller for contacting the material tray is provided on the side of the second driving block away from the second driving cylinder. The positioning is driven by the rolling contact between the roller and the periphery of the material tray, thereby achieving a better positioning effect and avoiding damage to the material tray.

[0068] In some embodiments, the tray unloading mechanism 700 also includes a product precision positioning module 760, which includes a product positioning platform 761, a first positioning unit 762 and a second positioning unit 763. The first positioning unit 762 and the second positioning unit 763 are respectively located on two adjacent sides of the product positioning platform 761. After the product is precisely positioned, the product is placed in the tray to achieve a high-precision operating effect.

[0069] It is understandable that a limit block for limiting the product is provided on the opposite side of the first positioning unit 762 and the second positioning unit 763, so that the product can achieve the effect of precise positioning under the joint action of the limit block, the first positioning unit 762 and the second positioning unit 763.

[0070] In some embodiments, the random drop test equipment for negative reviews also includes a scanning mechanism 800, which is located on one side of the product grabbing mechanism 300. After the product grabbing mechanism 300 grabs the product, it moves the product to the position of the scanning mechanism 800, and the scanning mechanism 800 scans the product to facilitate recording of the production process and subsequent data tracing.

[0071] The product random drop test equipment of the utility model can make the product that finally falls into the product drop collection box through the hollow cavity when the hollow cavity is located above the product drop collection box, and will be limited and interfered by the hollow cavity during the drop process, thereby producing a non-directional drop effect, thereby realizing a random drop test of the simulated product under natural use state; the hollow cavity can be moved to one side of the product drop collection box under the action of the moving mechanism, so that the CCD detection mechanism can detect the product position, so that the product grabbing mechanism can accurately grab the product, and the whole process does not require manual operation, thereby realizing the automatic operation effect and effectively reducing labor costs.
