Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic drop test system. Background Art

[0002] A drop tester is a test device specially used to test the drop damage and impact resistance of products during transportation and use. There are many types of drop testers on the market, and there are test equipment of different specifications for different test requirements of different products. The basic actions of a drop tester are grabbing, lifting and releasing. Some products need to undergo multiple drop tests. The existing drop tester can only grab one product at a time for a single drop test. In addition to being unable to meet the full inspection work of large production, it also requires repeated grabbing, lifting and releasing actions. Repeated actions take a lot of time, affecting test efficiency. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide an automatic drop test system which does not require a robot to grasp a product and can perform multiple drop tests, thereby improving the test efficiency.

[0004] In order to achieve the above object, the solution of the present invention is:

[0005] The lifting mechanism is a kind of lifting mechanism that lifts up and drops down, and the lifting mechanism of lifting up and drops down ...

[0006] After adopting the above scheme, when the present invention is used, the discharging mechanism pushes the products in multiple storage stations onto the conveyor belt, and multiple products can be output at one time. The conveyor belt sequentially transports the products toward the direction of the drop test mechanism. When the first product is transported to the top opening and closing plate of the drop test mechanism, other products are blocked by the blocking mechanism. The two opening and closing plates at the top layer are separated under the drive of the opposing cylinders, so that the product falls into the next layer of opening and closing plates. At the same time, the opposing cylinders at the top layer drive the two opening and closing plates to close together, ready to receive the second product. After the next layer of opening and closing plates senses the product, the opposing cylinders are started to allow the product to enter the next layer of opening and closing plates until the product falls into the pushing mechanism, and the pushing mechanism sends the product out, completing multiple drop tests of the same product. The present invention adopts a storage mechanism to replace the traditional manipulator to clamp the product. By setting a multi-layer openable and closable drop card plate through the drop test mechanism, multiple drop tests of the product can be realized, saving the time of the manipulator to repeatedly grab and release the product, and improving the test efficiency.

[0007] Furthermore, the automatic drop test system of the present invention also includes a feeding mechanism with a conveyor belt. One end of the conveyor belt of the feeding mechanism is connected to the conveyor belt of the storage mechanism, and the other end is connected to the drop test mechanism, so as to facilitate the transportation of the product. At the same time, the shape of the product can be converted through the feeding mechanism. For example, by setting the conveying direction of the conveyor belt of the feeding mechanism to be perpendicular to the conveying direction of the conveyor belt, the horizontally placed product can be converted to the vertically placed one.

[0008] Furthermore, the feeding mechanism is also provided with a force-applying mechanism, which includes a feeding cylinder, a feeding bracket, a feeding push plate and a pushing shield. The feeding cylinder is installed on the feeding bracket, and the feeding push plate is connected to the feeding cylinder. The pushing shield is arranged on one side of the feeding bracket, and one end of the feeding shield is engaged with the outer side of the topmost drop card plate of the drop test mechanism to prevent the feeding push plate from throwing the product out of the drop test mechanism when the feeding cylinder moves too fast.

[0009] Furthermore, the storage box includes a back plate arranged longitudinally, a support plate arranged at the bottom of the back plate, and a partition that divides the back plate into multiple storage stations.

[0027] The present invention is provided with a storage mechanism 2 having a plurality of storage stations, wherein the plurality of storage stations push products onto a conveyor belt 22 through a discharging mechanism 23, and the conveyor belt 22 sequentially transports the products toward a drop test mechanism 4. When the first product is transported to the top opening and closing plate of the drop test mechanism 4, other products are blocked by a blocking mechanism 24, and the two opening and closing plates at the top are separated under the drive of a counter-fire cylinder 43, so that the product falls into the next opening and closing plate. At the same time, the top counter-fire cylinder 43 drives the two opening and closing plates to close together, ready to receive the second product. After the next opening and closing plate senses the product, the counter-fire cylinder 43 is started, so that the product enters the next opening and closing plate, until the product falls into a pushing mechanism 44, and the pushing mechanism 44 sends the product out, completing multiple drop tests of the same product.

The two drop guide plates 46 on the same support plate 45 are inclinedly arranged with the upper one larger and the lower one smaller, so as to prevent the product from falling off the notch 451 of the support plate 45 when falling.

[0033] The pushing mechanism 44 of the drop test mechanism 4 can be as shown in the figure, including a drop bottom plate 441, a pushing plate 442 and a pushing cylinder 443. The pushing cylinder 443 is fixed on the drop bottom plate 441 and connected to the pushing plate 442. When the product falls to the drop bottom plate 441, the pushing cylinder 443 drives the pushing plate 442 to push the product to the outside of the drop bottom plate 441.

[0034] When the utility model is used, workers replenish products on the storage box 21 of the storage mechanism 2, or directly use the loading mechanism instead of manual loading. After loading is completed, the automatic drop test system of the present invention is started, and the products in each storage station can be discharged onto the conveyor belt 22 at one time through the discharging mechanism 23. When the products pass through the feeding mechanism 3, the feeding mechanism 3 is activated to push the products one by one to the top layer of the drop test mechanism 4, and the drop test of the products layer by layer is completed in the drop test mechanism 4, and finally discharged to the production line.

[0035] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
