[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings to provide a clearer understanding of the purpose, features, and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative of the essential spirit of the technical solution of the present invention.

[0021] The needle penetration sensitivity testing machine is used to assemble test components for impact testing. After the impact test, the test components are disassembled one by one for cleaning, and the process is repeated. The test components include several parts, in the following order: base, lead plate, plastic seat, flash cap, top cover, and firing pin. The lead plate is placed on the base of the test platform, the plastic seat is placed on the lead plate, the flash cap is placed on the plastic seat, and the top cover is fastened to the base to cover the flash cap. The firing pin is inserted into the top cover and contacts the flash cap. The impact test is completed by striking the flash cap with the firing pin.

[0022] This invention provides a feeding and storage mechanism for test accessories of a needle penetration sensitivity testing machine, used for storing and feeding lead plates or plastic seats.

[0023] like Figure 1 , Figure 2 As shown. This invention discloses a test accessory feeding and storage mechanism for a needle penetration sensitivity testing machine, comprising a feeding support 1, a guide plate 2, a pusher plate 3, a storage cylinder 4, and a first horizontal single-axis telescopic module 5. The guide plate 2 is disposed at the upper end of the feeding support 1, and the storage cylinder 4 is disposed on the guide plate 2 and communicates with the interior of the guide plate. The pusher plate 3 is embedded at the lower end of the guide plate 2. The first horizontal single-axis telescopic module 5 is disposed on the feeding support 1 and connected to one end of the pusher plate 3. The first horizontal single-axis telescopic module 5 extends and retracts, causing the pusher plate 3 to slide along the guide plate 2, pushing out the test accessory from the storage cylinder 4. The test accessory is a lead plate or a plastic base.

[0024] Specifically, the feeding support 1 is a directional frame, and a storage cylinder fixing seat 6 is provided on the guide plate 2, with the storage cylinder 4 fixed on the storage cylinder fixing seat 6. A U-shaped groove is provided on the lower surface of one end of the guide plate 2, and a material picking hole 21 is provided on the upper surface of the other end. The material picking hole 21 is a blind hole, and the bottom of the material picking hole 21 is not higher than the bottom of the U-shaped groove. The material picking hole 21 is connected to one end of the U-shaped groove. A discharge hole is provided on the upper surface of the guide plate 2, which is perpendicular to and connected to the U-shaped groove. The bottom of the storage cylinder 4 is connected to the U-shaped groove through the discharge hole. The lead plates are stacked in the storage cylinder 4 and can fall into the U-shaped groove layer by layer. The upper end of the feeding support 1 is fixed with a first horizontal single-axis telescopic module 5. The pusher plate 3 has an L-shaped structure, with one end slidably embedded in a U-shaped groove and the other end connected to the telescopic end of the first horizontal single-axis telescopic module 5. The first horizontal single-axis telescopic module 5 drives the pusher plate 3 to move back and forth, pushing the lead plates at the bottom of the storage cylinder 4 to the position of the picking hole 21 for the feeding gripping mechanism to grab. The storage cylinder 4 can hold 200 lead plates or plastic seats at a time, and the number can be adjusted according to actual needs.

[0025] Furthermore, the storage cylinder fixing base 6 includes a U-shaped base plate, ribs and clamps. The U-shaped base plate is embedded in the upper end of the guide plate 2. A through hole is opened in the middle of the U-shaped base plate. A pair of ribs are arranged perpendicularly on both sides of the U-shaped base plate. A pair of clamps are arranged at intervals between the upper and lower parts of the ribs. The storage cylinder 4 passes through the clamps and the through hole, and is inserted into the material extraction hole at the bottom. The storage cylinder 4 is fixed on the ribs by the clamps.

[0026] Furthermore, the first horizontal single-axis telescopic module 5 is preferably an electric telescopic rod or an electric telescopic rodless cylinder.

[0027] Furthermore, the storage cylinder 4 is provided with a slot along its outer circumference. At least two sets of slots are arranged in a radial array along the outer circumference of the storage cylinder. The slots penetrate the inner and outer circumferences of the storage cylinder 4. The slots facilitate workers to place lead plates or plastic seats. The inner circumference of the storage cylinder is fitted with the outer circumference of the lead plate or plastic seat with a clearance, which facilitates the lead plate or plastic seat to fall down in sequence. Each time the pusher plate 3 pushes out a lead plate or plastic seat, the lead plate or plastic seat above falls down into the U-shaped groove in sequence.

[0028] Furthermore, when the test accessory is a plastic base, due to its light weight, a counterweight is installed above the storage cylinder. The counterweight is used to balance the weight of the plastic base, facilitating its sequential placement into the U-shaped groove of the guide plate. The counterweight is connected to the storage cylinder via a flexible cable.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
