The firing pin 206 is struck to make the firing pin poke the primer 201 to complete the impact test. The present invention performs loading and assembly of the primer 201 and the firing pin 206 .

[0031] Example 1

[0032] Embodiment 1 The primer is assembled as follows: Figure 2-Figure 7 As shown. A test accessory loading assembly mechanism for a needle puncture sensitivity tester includes a test accessory loading storage sub-mechanism 2 and a test accessory loading grabbing sub-mechanism 1. The test accessory loading grabbing sub-mechanism 1 and the test accessory loading storage sub-mechanism 2 are spaced relative to each other and are used to grab the primer 201 on the test accessory loading storage sub-mechanism 2. The test accessory loading storage sub-mechanism 2 includes an XY biaxial moving module 21, a tray platform 22 and a tray 23. The tray platform 22 is slidably connected to the XY biaxial moving module 21. The tray 23 is arranged on the tray platform 22. The tray 23 is used to store the primer. The XY biaxial moving module 21 is used to drive the tray 23 to move. The test accessory loading grabbing sub-mechanism 1 includes a two-dimensional moving component and a grabbing component 14. The grabbing component 14 for grabbing the primer is arranged at one end of the two-dimensional moving component.

[0033] Specifically, the test accessory loading and storage sub-mechanism 2 is used to store the primer and transfer the primer to the grabbing position of the test accessory loading and grabbing sub-mechanism 1. The test accessory loading and grabbing sub-mechanism 1 grabs the primer 201 on the test accessory loading and storage sub-mechanism 2 and transfers it to the plastic seat 204 of the test carrier 1011 for assembly.

[0034] In the test accessory feeding and grabbing 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 arranged at the lower side of one end of the horizontal fixed plate 11, the vertical single-axis telescopic module 13 is arranged on the telescopic end of the horizontal single-axis moving module 12, and the grabbing component 14 is arranged on the telescopic end of the vertical single-axis telescopic module 13. The two-dimensional moving component can drive the grabbing component 14 to move vertically up and down and horizontally forward and backward.

[0035] In the test accessory loading and storage sub-mechanism 2, the XY biaxial moving module 21 is fixed on the module fixing seat 24, and the XY biaxial 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 primer to the material picking position where the grasping assembly 14 grasps the primer. The XY biaxial moving module 21 is preferably an XY bidirectional moving slide.

[0036] Furthermore, since the diameter of the detonator 201 is relatively small, the grabbing assembly 14 includes an adsorption sleeve 143 and an air pipe. The air pipe is connected to the telescopic end of the vertical uniaxial telescopic module 13 through a fixed plate. The lower end of the air pipe is connected to the adsorption sleeve 143. An air porous partition layer 1431 is provided inside the adsorption sleeve 143. The inner diameter of the adsorption sleeve matches the outer diameter of the detonator 201.

[0037] Specifically, the air hole partition 1431 divides the adsorption sleeve 143 into two cavities. The air hole partition 1431 is arrayed with a plurality of through holes, which penetrate the upper and lower cavities. The fire cap is sucked into the cavity at the lower end of the air hole partition 1431. After the air suction stops, the fire cap is removed from the lower cavity. The upper end of the adsorption sleeve is connected to an air suction component through an air pipe. The air suction component is preferably an air compressor, which is used to suck and exhaust air.

[0038] Furthermore, in order to facilitate the storage and placement of the primer 201, a storage rotating module 25 is provided on the XY biaxial moving module 21, and a tray carrier 22 is provided on the storage rotating module 25, and the positions of both ends of the tray are switched by the storage rotating module 25. A plurality of groove caps 231 are arrayed on the tray 23, and the groove caps 231 are used to accommodate the primer 201. The primer 201 is spaced in the groove caps 231, and the top of the primer 201 is slightly higher than the upper surface of the groove caps.

[0039] As a preferred embodiment, a pair of trays can be placed on the tray carrier 22 at the same time, and the storage rotating module 25 rotates to drive the positions of the pair of trays to switch with each other. The storage rotating module 25 is preferably an electric rotating cylinder or an electric rotating slide.

[0040] Furthermore, in order to facilitate the placement of the tray 23 , the tray carrier 22 is provided with mutually spaced positioning pins 221 , and the tray 23 is provided with mutually spaced positioning holes 233 , and the positioning pins 221 are inserted into the corresponding positioning holes 233 to achieve the limited fixation of the tray 23 .

[0041] As a preference, at least one pair of positioning holes 233 is provided at the bottom of each tray 23 , and a pair of positioning pins 221 is provided on the tray carrier 22 to cooperate with the positioning holes 233 .

[0042] Furthermore, in order to facilitate manual picking and placing of the pallet 23, and to consider convenient stacking design according to actual needs in the future, the pallet 23 is a rectangular plate structure, and grasping grooves 232 are respectively provided at both ends of the bottom of the pallet 23, and the grasping grooves 232 are opened at the lower part of the short end of the pallet 23.

[0043] When the test accessory loading and storage sub-mechanism 2 is working, the primer 201 is manually placed in the tray 23 in advance (the green paint end of the primer faces downward and the needle-pierced surface faces upward), the tray 23 is placed on the tray carrier 22 and fixed by the positioning pins, the XY dual-axis moving module 21 and the storage rotating module 25 move the primer 201 to the material removal position in sequence, and the test accessory loading and grabbing sub-mechanism 1 performs the corresponding action to grab the primer 201 and send it to the top of the plastic seat 204 for assembly.

[0044] Example 2

[0045] In Example 2, the firing pin 206 is loaded and assembled, which is different from Example 1 in that:

[0046] like Figure 8 , Fig. 9 As shown. The gripping assembly 14 of the second embodiment includes a clamping cylinder 141 and an accessory clamping finger 142. The clamping end of the clamping cylinder 141 is provided with a pair of accessory clamping fingers 142. The opposing surfaces of the pair of accessory clamping fingers 142 match the outer circumference of the firing pin. At the same time, the groove cap 231 on the tray 23 is used to accommodate a blind hole, and the blind hole can be inserted into the firing pin 206.

[0047] Specifically, a pair of accessory clamping fingers have semicircular grooves 1421 on their opposite surfaces. The semicircular grooves 1421 run through the upper and lower end surfaces of the accessory clamping fingers. The inner diameter of the semicircular grooves 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, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
