Description

Technical Field

[0001] This utility model relates to the technical field of detonator production equipment, and in particular to a detonator riser assembly machine. Background Technology

[0002] A detonator, also known as a detonating charge, is used to detonate low-sensitivity explosives such as ammonium nitrate oil (ANFO), slurry explosives, and emulsion explosives, as well as other explosives without detonator sensitivity. The detonation principle of a detonator involves inserting a detonator or detonating cord into it to detonate the detonator, which then detonates the low-sensitivity explosive. The detonator amplifies the detonation wave.

[0003] In the manufacturing process of detonators, one step is to install a riser on the top of the semi-finished detonator for injection. In the existing technology, the riser is usually placed in a placement mold, and then a robot is used to remove the riser and transfer it to the semi-finished detonator. The process of pre-placing the riser in the placement mold is relatively time-consuming, which makes it difficult to improve production efficiency. Utility Model Content

[0038] Example 1

[0039] Please refer to Figures 1 to 4 The first embodiment of this utility model is: a detonator riser assembly machine, used to assemble risers on the top plate of the detonator semi-finished product for injection at the next work station.

[0040] The detonator riser assembly machine includes a riser conveying line 1, a core mold conveying line 2, and a riser-retrieving robot 3. The riser conveying line 1 is used to convey risers; the core mold conveying line 2 is used to convey detonator core molds, and a portion of the core mold conveying line 2 is located above the riser conveying line 1. The core mold conveying line 2 has an assembly position and a clearance opening 11. The riser-retrieving robot 3 includes a two-axis moving platform 31, a rotating mechanism 32, and a variable-pitch material-retrieving mechanism 33 connected in sequence. The two-axis moving platform 31 is located above the core mold conveying line 2. The riser-retrieving robot 3 is used to remove at least one row of risers located on the riser conveying line 1 and corresponding to the clearance opening 11, and after increasing the distance between two adjacent risers, place the risers onto the detonator semi-finished product of the detonator core mold located at the assembly position.

[0041] It is easy to understand that the end position of the riser conveying line 1 corresponds to the avoidance port 11. Therefore, the limit position of the riser conveyed by the riser conveying line 1 is the area corresponding to the avoidance port 11. Specifically, the end position of the riser conveying line 1 is provided with a stop plate 21. The stop plate 21 is used to stop the riser on the riser conveying line 1, thereby preventing the riser from continuing to be conveyed forward.

[0042] To increase the number of risers that the riser-retrieving robot 3 can pick up and place at a time, thereby further improving production efficiency, a separator plate 22 is provided on the riser conveying line 1. The separator plate 22 is used to separate the multiple risers conveyed by the riser conveying line 1, so that the multiple risers corresponding to the avoidance port 11 area are arranged into n rows, where n is a positive integer greater than or equal to 2. The riser-retrieving robot 3 picks up n rows of risers on the riser conveying line 1 each time. In this embodiment, the value of n is 2. In other embodiments, when the number of separator plates 22 is two, the value of n is 3. In other embodiments, n can also be other specific values, such as 4, 5, 6, etc.

[0043] To prevent interference and collision between the detonator core mold conveyed by the core mold conveyor line 2 and the riser removal robot 3, a first light sensor 41 is provided at the avoidance opening 11. Preferably, the optical fiber emitted by the first light sensor 41 forms a light curtain, or multiple first sensors form a light curtain, thereby ensuring that the variable pitch material handling mechanism 33 will not collide with the detonator core mold during the lifting and lowering process.

[0044] The detonator riser assembly machine also includes a lifting and positioning mechanism 5, which is located at the assembly position. The lifting and positioning mechanism 5 includes a lifting mounting plate 51, a lifting drive component 52, a lifting plate 53, a positioning and lifting drive component 54, a positioning and lifting block 55, a positioning and clamping drive component 56, and a positioning clamping plate 57. The lifting drive component 52 and the positioning and lifting drive component 54 are respectively mounted on the lifting mounting plate 51. The lifting drive component 52 is connected to the lifting plate 53. The lifting plate 53 is used to lift the detonator core mold in the assembly position. The lifting plate 53 is provided with a lifting positioning post, which is used to cooperate with the positioning hole on the detonator core mold; the positioning lifting block 55 is connected to the positioning lifting drive 54, and the positioning clamping drive 56 is provided on the positioning lifting block 55. The clamping drive is connected to two cooperating positioning clamps 57. The positioning clamps 57 are used to clamp the positioning detonator semi-finished product. In order to better position and clamp the detonator semi-finished product, the positioning clamps 57 are provided with clamping notches, which are adapted to the detonator semi-finished product. It should be noted that the positioning clamps 57 can, to a certain extent, play a role in shaping the detonator semi-finished product, so that the riser can be assembled onto the detonator semi-finished product more smoothly. The lifting drive 52 can be a cylinder, electric push rod, hydraulic rod, etc., the positioning lifting drive 54 can be a cylinder, electric push rod, hydraulic rod, etc., and the positioning clamping drive 56 can be a clamping cylinder, etc.

[0045] In this embodiment, the two-axis moving platform 31 includes a translation drive 311, a first plate 312, a first lifting drive 313, a second plate 314, a second lifting drive 315, and a third plate 316 connected in sequence. The translation drive 311 drives the first plate 312 to move along a first direction, the first lifting drive 313 drives the second plate 314 to rise and fall, and the second lifting drive 315 drives the third plate 316 to rise and fall. The rotating mechanism 32 includes a rotating shaft, a linear drive, and an eccentric disk. The rotating shaft and the linear drive are rotatably mounted on the third plate 316. The eccentric disk is fixedly connected to the rotating shaft, and the linear drive is rotatably connected to the eccentric disk. The rotating shaft is connected to the variable-pitch material handling mechanism 33. The translation drive component 311 can be a cylinder, an electric push rod, a hydraulic rod, etc.; the first lifting drive component 313 can be a cylinder, an electric push rod, a hydraulic rod, etc.; the second lifting drive component 315 can be a cylinder, an electric push rod, a hydraulic rod, etc.; and the linear drive component can be a cylinder, an electric push rod, a hydraulic rod, etc. In other embodiments, the rotating mechanism 32 can be directly selected as a motor. In this embodiment, using a linear drive component as the power source can reduce the overall size of the rotating mechanism 32.

[0046] The variable pitch material handling mechanism 33 includes a variable pitch frame 331, a variable pitch drive component 332, multiple variable pitch sliders 333, and multiple variable pitch connecting rods 334. The variable pitch frame 331 connects the rotating mechanism 32 and the variable pitch drive component 332. Multiple variable pitch sliders 333 are slidably mounted on the variable pitch frame 331. Each variable pitch connecting rod connects two adjacent variable pitch sliders 333. The bottom of each variable pitch slider 333 is provided with several clamping components 335, each of which can clamp a riser. The variable pitch drive component 332 can be a cylinder, an electric push rod, a hydraulic rod, etc. The variable pitch material handling mechanism 33 has a simple structure and stable operation.

[0047] The detonator riser assembly machine also includes a pressure detection mechanism 6. The pressure detection mechanism 6 includes a pressure frame 61, a pressure plate 62, a lifting drive component 63, a lifting plate 64, and a second light sensor 42. The pressure frame 61 and the lifting drive component 63 are respectively mounted on the core mold conveying line 2. The pressure plate 62 is mounted on the pressure frame 61 and located above the core mold conveying line 2. The lifting drive component 63 is connected to the lifting plate 64 to drive the lifting plate 64 to rise and fall. The lifting plate 64 is positioned corresponding to the pressure plate 62 and is used to lift the detonator core mold. The second light sensor 42 is mounted on the pressure frame 61 and is used to detect whether the detonator semi-finished product is missing a riser. The pressure plate 62 is used to press down on the riser on the detonator semi-finished product. The lifting drive component 63 can be a cylinder, an electric push rod, a hydraulic rod, etc.

[0048] The pressure testing mechanism 6 also includes an elastic element 65. The pressure plate 62 is vertically adjustable relative to the pressure frame 61, and the elastic element 65 contacts both the pressure plate 62 and the pressure frame 61. This improves the versatility of the detonator riser assembly machine and enhances the riser assembly quality. The elastic element 65 can be a spring or similar component.

[0049] The working process of the detonator riser assembly machine is briefly described as follows:

[0050] The riser-retrieving robot 3 moves above the clearance opening 11. The first lifting drive 313 drives the variable-pitch material-retrieving mechanism 33 to descend and at least partially pass through the clearance opening 11, thereby clamping the riser located on the riser conveyor line 1. Then, the first lifting drive 313 drives the variable-pitch material-retrieving mechanism 33 to rise, and the translation drive 311 drives the variable-pitch material-retrieving mechanism 33 to move above the assembly position. At the same time, the rotation mechanism 32 drives the variable-pitch material-retrieving mechanism 33 to rotate 90°, and the variable-pitch drive 332 drives the distance between two adjacent variable-pitch sliders 333 to increase. The lifting drive 52 drives the detonator core mold located in the placement position to rise, the positioning lifting drive 54 drives the positioning clamping plate 57 to descend, and the clamping drive drives the positioning plate 57 to descend. Positioning clamp 57 holds the detonator semi-finished product on the detonator core mold. Then, the second lifting drive 315 drives the variable pitch material handling mechanism 33 to descend, thereby assembling the riser onto the detonator semi-finished product. Then, the riser removal robot 3 resets, and the positioning lifting drive 54 drives the positioning clamp 57 to rise so that the detonator core mold conveyed on the core mold conveyor line 2 can pass under the positioning clamp 57. Finally, the detonator semi-finished product with the riser assembled is conveyed by the core mold conveyor line 2 to the pressure detection mechanism 6. The lifting drive 63 drives the lifting plate 64 to lift the detonator core mold, so that the riser on the detonator semi-finished product abuts against the pressure plate 62. At the same time, the second light sensor 42 detects whether the detonator semi-finished product is missing a riser.
