Description

Technical Field

[0001] This invention belongs to the technical field of needle penetration sensitivity testing equipment, specifically relating to a feeding and assembly mechanism for test accessories used in a needle penetration sensitivity testing machine. Background Technology

[0002] Needle penetration sensitivity refers to the degree of difficulty for an initiating explosive to explode under the action of a needle. It is evaluated by dropping a steel ball (or hammer) of a certain mass from different heights to strike the firing pin, and then observing the ignition of the firing pin.

[0003] Needle penetration sensitivity testing is one of the important means to evaluate the safety and reliability of pyrotechnics. The traditional testing method is to manually assemble the test components and then strike the firing pin, which is not only inefficient but also has poor test accuracy. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a test accessory feeding and assembly mechanism for a needle penetration sensitivity testing machine. This assembly mechanism automatically combines the storage and retrieval of test accessories, thereby realizing the automatic feeding and assembly process of test accessories and solving the problem of low efficiency in traditional manual operation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A test accessory loading and assembly mechanism for a needle penetration sensitivity testing machine includes a test accessory loading and storage sub-mechanism and a test accessory loading and gripping sub-mechanism, which are spaced apart and opposite to each other. The test accessory loading and storage sub-mechanism includes an XY dual-axis moving module, a tray platform, and a tray. The tray platform is slidably connected to the dual-axis moving module, and the tray for storing test accessories is disposed on the tray platform. The XY dual-axis moving module is used to drive the tray to move. The test accessory loading and gripping sub-mechanism includes a two-dimensional moving component and a gripping component. One end of the two-dimensional moving component is provided with the gripping component for gripping the test accessories.

[0007] Furthermore, the dual-axis moving module is provided with a storage rotating module, and the storage rotating module is provided with the tray platform.

[0008] Furthermore, the tray is arrayed with recessed caps for accommodating the test accessories.

[0009] Furthermore, the pallet platform is provided with mutually spaced positioning pins, and the pallet is provided with mutually spaced positioning holes, with the positioning pins inserted into the corresponding positioning holes.

[0010] Furthermore, gripping grooves are provided at least at opposite ends of the bottom of the tray.

[0011] Furthermore, the two-dimensional moving component includes a horizontal fixed plate, a horizontal single-axis moving module, and a vertical single-axis telescopic module. The horizontal single-axis moving module is disposed on the lower side of one end of the horizontal fixed plate, and the vertical single-axis telescopic module is disposed on the telescopic end of the horizontal single-axis moving module. The gripping component is disposed on the telescopic end of the vertical single-axis telescopic module.

[0012] Furthermore, the gripping component includes an adsorption sleeve, and the adsorption sleeve has an air-porous partition inside.

[0013] Furthermore, the gripping component includes a clamping cylinder and accessory clamping fingers, and the clamping end of the clamping cylinder is provided with a pair of accessory clamping fingers.

[0014] Furthermore, semi-circular grooves are provided on the opposing surfaces of the fingers holding the pair of accessories.

[0015] Furthermore, the vertical single-axis telescopic module is an electric telescopic rod or an electric telescopic rodless cylinder.

[0016] Because the present invention adopts the above technical solution, it has the following advantages and effects:

[0017] (1) The present invention provides a test accessory feeding and assembly mechanism for a needle penetration sensitivity testing machine. The assembly mechanism realizes the automatic feeding and assembly process of test accessories such as spark caps or firing pins through the cooperation of a test accessory feeding and storage sub-mechanism and a test accessory feeding and gripping sub-mechanism. This not only improves work efficiency and reduces labor intensity, but also ensures the accuracy and consistency of test operations.

[0018] (2) The present invention provides a test accessory loading and assembly mechanism for a needle penetration sensitivity testing machine. The test accessory loading and storage sub-mechanism can effectively store and position the spark cap or firing pin by using a combination of an XY dual-axis moving module, a tray platform and a tray, which facilitates subsequent gripping operations. The test accessory loading and gripping sub-mechanism achieves precise gripping and placement of the spark cap or firing pin through the synergistic effect of the two-dimensional moving component and the gripping component.

Detailed Implementation

[0029] 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.

[0030] like Figure 1As shown. The needle penetration sensitivity testing machine is used to assemble the test component 20 and conduct an impact test. After the impact test is completed, the test components are disassembled one by one for cleaning, and the process is repeated. The test component 20 includes multiple test accessories, namely, a flash cap 201, a base 202, a lead plate 203, a plastic seat 204, a top cover 205, and a firing pin 206. During the test, the base 202 is placed on the base positioning seat 1012 of the product platform 1011, and the top cover 205 is placed on the top cover positioning seat 1013 of the product platform 1011. Then, the lead plate 203 is placed on the base 202, the plastic seat 204 is placed on the lead plate 203, the flash cap 201 is placed on the plastic seat 204, and the top cover 205 is fastened to the base 202 to cover the flash cap 201. The firing pin 206 is inserted into the top cover 205 and contacts the flash cap 201. The impact test is completed by striking the flash cap 201 with the firing pin 206. This invention involves the loading and assembly of the firing cap 201 and the firing pin 206.

[0031] Example 1

[0032] Example 1 describes the assembly of the fire cap, such as... Figures 2-7 As shown. A test accessory loading and assembly mechanism for a needle penetration sensitivity testing machine includes a test accessory loading and storage sub-mechanism 2 and a test accessory loading and gripping sub-mechanism 1. The test accessory loading and gripping sub-mechanism 1 and the test accessory loading and storage sub-mechanism 2 are spaced apart and used to grip the burner cap 201 on the test accessory loading and storage sub-mechanism 2. The test accessory loading and storage sub-mechanism 2 includes an XY dual-axis moving module 21, a tray platform 22, and a tray 23. The tray platform 22 is slidably connected to the XY dual-axis moving module 21, and the tray 23 is disposed on the tray platform 22. The tray 23 is used to store the burner cap, and the XY dual-axis moving module 21 is used to move the tray 23. The test accessory loading and gripping sub-mechanism 1 includes a two-dimensional moving component and a gripping component 14. One end of the two-dimensional moving component is provided with the gripping component 14 for gripping the burner cap.

[0033] Specifically, the test accessory loading and storage sub-mechanism 2 is used to store the fire caps and transfer the fire caps to the gripping position of the test accessory loading and gripping sub-mechanism 1. The test accessory loading and gripping sub-mechanism 1 grips the fire caps 201 on the test accessory loading and storage sub-mechanism 2 and transfers them to the plastic seat 204 of the test platform 1011 for assembly.

[0034] In the test accessory loading and gripping sub-mechanism 1, the two-dimensional moving component includes a horizontal fixed plate 11, a horizontal single-axis moving module 12, and a vertical single-axis telescopic module 13. The horizontal single-axis moving module 12 is located on the lower side of one end of the horizontal fixed plate 11. The vertical single-axis telescopic module 13 is located on the telescopic end of the horizontal single-axis moving module 12, and the gripping component 14 is located on the telescopic end of the vertical single-axis telescopic module 13. The two-dimensional moving component can drive the gripping component 14 to move vertically up and down and horizontally back and forth.

[0035] In the test accessory loading and storage sub-mechanism 2, the XY dual-axis moving module 21 is fixed on the module fixing base 24. The XY dual-axis moving module 21 can drive the tray 23 to move along the XY horizontal direction to adjust the position of the tray 23, thereby moving the flame cap to the picking position of the gripping component 14 to grip the flame cap. The XY dual-axis moving module 21 is preferably an XY bidirectional moving slide.

[0036] Furthermore, since the diameter of the flame cap 201 is small, the gripping component 14 includes an adsorption sleeve 143 and an air pipe. The air pipe is connected to the telescopic end of the vertical single-axis telescopic module 13 through a fixing plate. The lower end of the air pipe is connected to the adsorption sleeve 143. The adsorption sleeve 143 has an air hole partition 1431 inside. The inner diameter of the adsorption sleeve matches the outer diameter of the flame cap 201.

[0037] Specifically, the porous partition 1431 divides the adsorption sleeve 143 into two chambers. The porous partition 1431 has several through holes arranged in an array, connecting the upper and lower chambers. The flame cap is drawn into the lower chamber of the porous partition 1431, and after the adsorption stops, the flame cap detaches from the lower chamber. The upper end of the adsorption sleeve is connected to an air intake assembly via an air pipe. The air intake assembly is preferably an air compressor, which draws in and exhausts air.

[0038] Furthermore, to facilitate the storage and placement of the burner cap 201, a storage rotation module 25 is provided on the XY dual-axis moving module 21. A tray platform 22 is provided on the storage rotation module 25, and the positions of the two ends of the tray are switched through the storage rotation module 25. Several recessed caps 231 are arrayed on the tray 23. The recessed caps 231 are used to accommodate the burner cap 201. The burner caps 201 are spaced apart within the recessed caps 231, and the top of the burner cap 201 is slightly higher than the upper surface of the recessed cap.

[0039] As a preferred embodiment, a pair of trays can be placed on the tray platform 22 simultaneously, and the rotation of the storage rotation module 25 causes the positions of the pair of trays to switch between each other. The storage rotation module 25 is preferably an electric rotary cylinder or an electric rotary slide.

[0040] Furthermore, in order to facilitate the placement of the tray 23, the tray platform 22 is provided with mutually spaced positioning pins 221, and the tray 23 is provided with mutually spaced positioning holes 233. The tray 23 is fixed by inserting the positioning pins 221 into the corresponding positioning holes 233.

[0041] As a preferred embodiment, each tray 23 has at least one pair of positioning holes 233 at its bottom, and a pair of positioning pins 221 on the tray platform 22 that engage with the positioning holes 233.

[0042] Furthermore, in order to facilitate manual handling of pallet 23 and to facilitate stacking design according to actual needs, pallet 23 is a rectangular plate structure with gripping grooves 232 at both ends of the bottom of pallet 23. The gripping grooves 232 are located at the lower part of the short end of pallet 23.

[0043] When the test accessory loading and storage sub-mechanism 2 is working, the manual person places the igniter 201 in the tray 23 in advance (with the green paint end of the igniter facing down and the needle side facing up), places the tray 23 on the tray platform 22 and fixes it by positioning pins, and moves the XY dual-axis moving module 21 and the storage rotating module 25 to move the igniter 201 to the picking position in sequence. The test accessory loading and gripping sub-mechanism 1 then performs the corresponding action to grip the igniter 201 and send it to the plastic seat 204 for assembly.

[0044] Example 2

[0045] Example 2 involves loading and assembling the firing pin 206, which differs from Example 1 in that:

[0046] like Figure 8 , Figure 9 As shown. The gripping assembly 14 of Embodiment 2 includes a gripping cylinder 141 and accessory gripping fingers 142. A pair of accessory gripping fingers 142 are provided at the gripping end of the gripping cylinder 141, and the opposing surfaces of the pair of accessory gripping fingers 142 respectively match the outer peripheral surface of the firing pin. At the same time, the groove cap 231 on the tray 23 is used to accommodate a blind hole, into which the firing pin 206 can be inserted.

[0047] Specifically, a semi-circular groove 1421 is provided on the opposing surfaces of a pair of accessory clamping fingers. The semi-circular groove 1421 passes through the upper and lower end faces of the accessory clamping fingers, and the inner diameter of the semi-circular groove 1421 is slightly smaller than the outer diameter of the firing pin 206.

[0048] 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.
