Description

Technical Field

[0001] This invention relates to the field of detonator manufacturing equipment technology, and particularly to a detonator top cover 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] Detonator core molds are used in the production process of detonators. Figure 1 A detonator core mold 100 is shown, comprising a core mold base plate and multiple core mold assemblies 200 disposed on the core mold base plate. During the manufacturing process of the detonator, one step involves installing a top cover 400 onto the top of a cylindrical body 300 fitted onto the core mold base of the core mold assembly 200. The top cover 400 has multiple holes 4001 through which the mandrels of the core mold assembly 200 pass. These holes 4001 vary in size; therefore, during the installation of the top cover onto the cylindrical body, the holes on the top cover must be aligned with the corresponding mandrels. Otherwise, the top cover and the cylindrical body cannot be assembled. Existing technology generally uses visual inspection to detect the position of the holes on the top cover, then rotates and adjusts the top cover before assembling it onto the cylindrical body. This process is time-consuming, and the corresponding mechanism is complex, resulting in a high manufacturing cost for the detonator top cover assembly machine. Summary of the Invention

[0004] The technical problem solved by this invention is to provide a high-efficiency detonator top cover assembly machine.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a detonator cover assembly machine, comprising:

[0006] The upper cover feeding mechanism includes an upper cover feeding robot arm;

[0007] The cover transfer mechanism includes a platform conveyor line and a cover platform provided on the platform conveyor line. The cover platform is provided with a plurality of cover placement slots for receiving covers conveyed by the cover loading robot. The platform conveyor line has a receiving position, an adjustment position and a unloading position arranged in sequence.

[0008] The upper cover rotation mechanism is located at the adjustment position. The upper cover rotation mechanism includes an adjustment frame, an adjustment lifting drive, an adjustment lifting frame, and multiple sets of rotation drive components. The adjustment lifting drive is located on the adjustment frame and connected to the adjustment lifting frame to drive the adjustment lifting frame to move up and down. The rotation drive components include a rotation drive and a rotation head. The rotation drive is located on the adjustment lifting frame and connected to the rotation head to drive the rotation head to rotate. The rotation head is located above the platform conveyor line. The bottom of the rotation head is provided with multiple elastic pins, which are retractable in the vertical direction.

[0009] A core mold conveyor line, wherein the core mold conveyor line is used to convey the detonator core mold;

[0010] The upper cover unloading robot is used to transfer the upper cover on the upper cover platform at the unloading position to the cylindrical body on the detonator core mold, and pre-press the bottom end of the upper cover into the cylindrical body on the detonator core mold;

[0011] The upper cover pressing mechanism is located on the core mold conveying line and is used to perform secondary pressing on the upper cover that is pre-pressed into the cylindrical body at the bottom end.

[0012] The beneficial effects of this invention are as follows: The detonator cover assembly machine has a novel structure; the adjustment of the holes on the cover does not require visual inspection, and the cover can be adjusted to the preset position using a purely mechanical structure, which helps improve production efficiency. Furthermore, the absence of visual inspection equipment also helps control the manufacturing cost of the detonator cover assembly machine. The cover is assembled with the cylindrical body through secondary pressing, which helps improve the assembly quality of the cover and reduce the production defect rate. Attached Figure Description

[0039] Example 1

[0040] Please refer to Figures 2 to 7 The first embodiment of the present invention is as follows: Please refer to... Figure 2 and Figure 3 A detonator cover assembly machine includes a cover loading mechanism 1, a cover transfer mechanism 2, a cover rotation mechanism 3, a core mold conveyor line 4, a cover unloading robot 5, and a cover pressing mechanism 6. The cover loading mechanism 1 includes a cover loading robot 11. The cover transfer mechanism 2 includes a platform conveyor line 21 and a cover platform 22 mounted on the platform conveyor line 21. The cover platform 22 has multiple cover placement slots for receiving covers conveyed by the cover loading robot 11. The platform conveyor line 21 has a receiving position, an adjustment position, and an unloading position arranged sequentially. The cover rotation mechanism 3 is located at the adjustment position and includes an adjustment frame 31, an adjustment lifting drive component 32, an adjustment lifting frame 33, and multiple sets of rotation drive components. The adjustment lifting drive component 32 is mounted on the adjustment frame 31 and connected to the adjustment lifting frame 33 to drive... The adjusting lifting frame 33 is raised and lowered. The rotary drive assembly includes a rotary drive component 341 and a rotary head 342. The rotary drive component 341 is mounted on the adjusting lifting frame 33 and connected to the rotary head 342 to drive the rotary head 342 to rotate. The rotary head 342 is located above the platform conveyor line 21. The bottom of the rotary head 342 is provided with multiple elastic pins 343, which are retractable in the vertical direction. The core mold conveyor line 4 is used to convey the detonator core mold. The upper cover unloading robot 5 is used to transfer the upper cover on the upper cover platform 22 at the unloading position to the cylindrical body on the detonator core mold, and pre-press the bottom end of the upper cover into the cylindrical body on the detonator core mold. The upper cover pressing mechanism 6 is mounted on the core mold conveyor line 4 and is used to perform secondary pressing on the upper cover whose bottom end is pre-pressed into the cylindrical body. The upper cover platform 22 receives the upper cover conveyed by the upper cover loading robot 11 at the receiving position.

[0041] The adjusting lifting drive component 32 can be a linear cylinder, an electric push rod, etc.; the rotating drive component 341 can be a motor, a rotary cylinder, etc.

[0042] Specifically, the resilient pin 343 includes a resilient element and a pin. The resilient element contacts the pin and the rotating head 342. The pin should be adapted to fit a hole on the upper cover. Therefore, when the upper cover has multiple holes of different diameters for mating with the pins, at least two pins of different diameters are installed on the same rotating head 342. The resilient element can be a spring, compression spring, spring washer, etc.

[0043] The upper cover feeding mechanism 1 further includes an upper cover vibration feeding component 12, an upper cover pushing component 13, and an upper cover pitch changing component 14. The upper cover pitch changing component 14 includes an upper cover pitch changing drive and an upper cover pitch changing disk 141. The upper cover pitch changing drive is connected to the upper cover pitch changing disk 141 to drive the upper cover pitch changing disk 141 to move linearly. The upper cover pitch changing disk 141 is provided with a plurality of upper cover temporary storage slots 142. The plurality of upper cover temporary storage slots 142 are arranged in at least one row. The upper cover temporary storage slots 142 are connected to the peripheral wall of the upper cover pitch changing disk 141 to form an upper cover inlet. The upper cover pushing component 13 is used to push the upper cover located at the output end of the upper cover vibration feeding component 12 into the upper cover temporary storage slot 142 through the upper cover inlet. The upper cover feeding robot 11 is used to transfer the upper cover in the upper cover temporary storage slot 142 to the upper cover placement slot. The upper cover vibration feeding assembly 12 includes a connected upper cover vibrating plate 121 and an upper cover conveyor 122. The upper cover pushing assembly 13 pushes each upper cover transported to the end of the upper cover conveyor 122 into each upper cover temporary storage slot 142 of the upper cover pitch changing plate 141, thereby completing the pitch changing of multiple upper covers so that the upper cover feeding robot 11 can grasp them. It is easy to understand that the upper cover pitch changing drive drives the upper cover pitch changing plate 141 to move in a stepping manner. The upper cover pitch changing drive can be a stepper motor or the like.

[0044] To improve feeding efficiency, in this embodiment, there are two upper cover vibration feeding components 12 and two upper cover pushing components 13. The upper cover vibration feeding components 12 and the upper cover pushing components 13 correspond one-to-one. The upper cover variable pitch disk 141 has two rows of upper cover temporary storage slots 142. The two upper cover pushing components 13 are located on both sides of the upper cover variable pitch disk 141.

[0045] Please combine Figure 2 and Figure 5To improve the working stability of the detonator cover assembly machine, the detonator cover assembly machine also includes a first lifting and positioning mechanism 7. The first lifting and positioning mechanism 7 is disposed on the core mold conveyor line 4. The first lifting and positioning mechanism 7 includes a lifting mounting plate 71, a lifting drive component 72, a lifting plate 73, a positioning lifting drive component 74, a positioning lifting block 75, a positioning clamping drive component 76, and a positioning clamping plate 77. The lifting drive component 72 and the positioning lifting drive component 74 are respectively mounted on the lifting mounting plate 71. 72 connects to the lifting plate 73, which is used to lift the detonator core mold on the core mold conveyor line 4. The positioning lifting block 75 is connected to the positioning lifting drive 74. The positioning clamping drive 76 is disposed on the positioning lifting block 75. The clamping drive 76 is connected to two cooperating positioning clamping plates 77, which are used to position the cylindrical body on the detonator core mold. The upper cover unloading robot 5 transfers the upper cover to the cylindrical body on the detonator core mold located on the lifting plate 73. The clamping drive can be a clamping cylinder, etc.

[0046] To better position and clamp the cylindrical body, the positioning clamp 77 is provided with a clamping notch 5272 that adapts to the outer wall of the cylindrical body. It should be noted that the positioning clamp 77 with the clamping notch 5272 can, to some extent, shape the cylindrical body, allowing the top cover to be assembled more smoothly onto the cylindrical body. The lifting drive component 72 can be a cylinder, an electric push rod, a hydraulic rod, etc., the positioning lifting drive component 74 can be a cylinder, an electric push rod, a hydraulic rod, etc., and the positioning clamping drive component 76 can be a clamping cylinder, etc.

[0047] Similarly, the detonator cover assembly machine also includes a second lifting and positioning mechanism 8 with the same structure as the first lifting and positioning mechanism 7. The second lifting and positioning mechanism 8 is set to correspond to the cover pressing mechanism 6. In this way, the cover pressing mechanism 6 can also press the cover more firmly, so that the cover and the cylindrical body can be assembled more tightly.

[0048] Please combine Figure 2 and Figure 4To improve the versatility of the cover unloading robot 5 and enable it to effectively adapt to cylindrical bodies of different heights and dimensions, the cover unloading robot 5 includes a shifting drive 51, an adjusting frame 52, and a cover clamping assembly 53. The shifting drive 51 is connected to the adjusting frame 52 to drive the adjusting frame 52 to move above the unloading position and the core mold conveyor line 4. The shifting drive 51 can be a cylinder, an electric push rod, a hydraulic rod, etc. The adjusting frame 52 includes a top plate 521, an adjusting lifting drive 522, an adjusting lifting plate 523, a guide post 524, a limiting plate 525, a height limiting post 526, and an adjusting disc 527. The top plate 521 is connected to the shifting drive 51, and the adjusting lifting drive 522 is connected to the top plate 521 and the adjusting lifting plate 523 to drive the adjusting lifting plate 523 to rise and fall. The adjusting lifting drive component 522 can be a cylinder, an electric push rod, a hydraulic rod, etc.; the guide post 524 is fixed on the adjusting lifting plate 523, and the top plate 521 is provided with a guide hole for the top end of the guide post 524 to pass through. The limiting plate 525 is located above the top plate 521 and connects the height limiting post 526 and the guide post 524. The adjusting plate 527 is rotatably mounted on the top plate 521. The top surface of the adjusting plate 527 is provided with multiple adjusting slots 5271 of different depths along the circumference. The height limiting post 526 corresponds to one of the adjusting slots 5271. The upper cover clamping assembly 53 is located at the bottom of the adjusting lifting plate 523. Optionally, the bottom of the adjusting lifting plate 523 is also provided with a pressure post 54 for pressing against the top surface of the upper cover. The presence of the pressure post 54 allows the upper cover to be assembled into the cylindrical body more smoothly. When the height limiting post 526 corresponds to the adjustment slot 5271 at different depths, the descent stroke of the adjustment lifting plate 523 will be different, so that the top cover unloading robot 5 can be used to assist in the manufacture of detonators of different heights, thus improving the versatility of the top cover unloading robot 5.

[0049] In this embodiment, the top plate 521 is also provided with a locking component for the adjustment disk 527. Optionally, the locking component is a lifting plunger 55. The adjustment disk 527 is provided with a plurality of notches 5272 that cooperate with the lifting plunger 55. When the lifting plunger cooperates with different notches 5272, the height limiting post 526 corresponds to the adjustment groove 5271 of different depths.

[0050] In a preferred embodiment, the number of guide posts 524 in the adjustment frame 52 is multiple, and the limiting plate 525 connects at least two of the guide posts 524; the number of adjustment discs 527 and height limiting posts 526 in the adjustment frame 52 are multiple, and they correspond one-to-one. Preferably, the multiple height limiting posts 526 connected to the same limiting plate 525 are respectively arranged close to different guide posts 524, so as to balance the force on the adjustment frame 52 and improve the working stability of the adjustment frame 52.

[0051] Please combine Figure 2 and Figure 6 It is not difficult to understand that the upper cover pressing mechanism 6 includes the adjusting frame 52 and an upper cover pressing block 61 fixed to the bottom of the adjusting lifting plate 523 in the adjusting frame 52. That is to say, the upper cover pressing mechanism 6 also has a set of the aforementioned adjusting frame 52, except that the bottom of the adjusting frame 52 is not equipped with the upper cover clamping assembly 53 and the pressing column 54, but with the upper cover pressing block 61.

[0052] Please combine Figure 2 and Figure 7 In one or more embodiments, the detonator cover assembly machine further includes a light detection mechanism 9 disposed on the core mold conveying line 4. The light detection mechanism 9 includes a detection frame 91, an XY-axis moving platform 92 disposed on the detection frame 91, and multiple light sensors 93 disposed on the XY-axis moving platform 92. The light sensors 93 are located above the core mold conveying line 4 and are used to detect the distance between each area of ​​the top surface of the cover on the detonator core mold and the light sensor 93. Driven by the XY-axis moving platform 92, the light sensors 93 can detect the distance between each area of ​​the top surface of the cover and the light sensor 93. When the detected distance data exceeds a preset range, it is determined that there is a detonator semi-finished product with a poorly assembled cover on the detected detonator core mold.

[0053] like Figure 2 As shown, the detonator cover assembly machine also includes a defective product collection mechanism 10, which is located at the lower station of the light detection mechanism 9. The defective product collection mechanism 10 includes a collection platform and a defective product pushing component. The defective product pushing component is used to push the detonator core mold on the core mold conveying line 4 onto the collection platform.

[0054] The working process of the explosive device cover assembly machine in this case is briefly described as follows:

[0055] The top cover loading robot places the gripped top cover onto the top cover platform. The platform conveyor moves the top cover platform to the adjustment position. The adjustment lifting drive drives the adjustment lifting frame to descend, so that the bottom surface of the pin contacts the top surface of the top cover. When the hole on the top cover is misaligned with the corresponding pin, the pin retracts into the rotating head, the elastic element is compressed, and the rotation drive drives the rotating head to rotate one revolution. During the rotation of the rotating head, the hole on the top cover aligns with the corresponding pin, the elastic element recovers its deformation, and the pin is inserted into the corresponding hole of the top cover. The rotating head continues to rotate, which will drive the top cover to rotate, thereby rotating the top cover to the preset position and completing the adjustment of the top cover.

[0056] Once all the covers on the upper cover platform have been adjusted, the platform conveyor line moves the upper cover platform to the unloading position, ready for the upper cover unloading robot to unload.

[0057] The lifting drive in the first lifting and positioning mechanism drives the detonator core mold on the core mold conveyor line to rise, the positioning and lifting drive drives the positioning clamping plate to fall, and the clamping drive drives the positioning clamping plate to clamp the cylindrical body on the detonator core mold. Then, the upper cover unloading robot inserts the bottom end of the upper cover it has clamped into the top of the cylindrical body. Then, the upper cover unloading robot resets, the positioning and lifting drive drives the positioning clamping plate to rise so that the detonator core mold conveyed on the core mold conveyor line can pass under the positioning clamping plate. The first lifting and positioning mechanism resets, and the detonator core mold flows to the lower station of the core mold conveyor line.

[0058] The second lifting and positioning mechanism works in the same way as the first lifting and positioning mechanism. After the positioning clamp in the second lifting and positioning mechanism clamps the cylindrical body on the detonator core mold, the upper cover pressing mechanism presses the upper cover on the cylindrical body a second time. The second lifting and positioning mechanism is reset, and the detonator core mold flows to the lower station of the core mold conveying line.

[0059] The light inspection mechanism performs a top surface plane inspection on the assembled top cover to distinguish between good and defective products. Detonator core molds carrying defective products are transferred to the collection platform, while detonator core molds carrying all good detonator semi-finished products continue to flow to the next station along the core mold conveyor line.

[0060] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
