Description

Technical Field

[0001] This invention relates to the field of non-standard equipment technology, and more specifically, to an electronic detonator production line. Background Technology

[0056] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0057] Please see Figure 1An embodiment of the present invention provides an electronic detonator production line, comprising: a conveying fixture 1 for placing electronic detonators, the conveying fixture being conveyed by a conveyor belt; and sequentially arranged on the side of the conveyor belt are an electronic detonator winding and binding mechanism 2, an electronic detonator outer sheath stripping and wire separating mechanism 3, an inner core twisting device 4, an end injection molding device 5, a wire box crimping device 6, an injection plug inner core stripping and cutting device 7, and an automatic discharge device 8.

[0058] The electronic detonator winding and tying mechanism is used to wind the cable into a bundle, tie a cable tie to the bundle, and place the bundle on the conveying fixture.

[0059] The electronic detonator stripping and wire separating mechanism is used to strip the outer sheath of the two ends of the wire handle and separate the two core wires at the ends of the wire handle.

[0060] The inner core twisting device is used to twist the two core wires at the end of the wire bundle so that the two wires are intertwined.

[0061] The injection molding device is used to perform injection molding at one end of the wire handle and form an injection plug at that end, with the front end of the injection plug having an extended wire from the inner wire of the wire handle.

[0062] The junction box crimping device is used to crimp a junction box to the other end of the wire handle.

[0063] The injection plug inner core stripping and cutting device is used to strip the outer sheath of the inner wire protruding from the front end of the injection plug.

[0064] See Figures 2 to 5 The electronic detonator winding and binding mechanism 2 includes an automatic lead wire feeding device 21 and a winding mechanism 22 disposed on one side of the automatic lead wire feeding device 21. The automatic lead wire feeding device 22 includes a drive module 2210 for driving the wound wire bundle, a tensioning module 2211 for tensioning the wire bundle disposed on one side of the drive module 2210, and a winding wheel feeding step 2212 for guiding the winding wheel feeding on the other side of the drive module 2210. The drive module 2210 includes a drive roller 2210a, a first driven roller 2210b disposed in front of the drive roller 2210a, and a second driven roller 2210c disposed behind the drive roller. 2210 is used to drive the reel 227 that winds the wire bundle. The reel 227 includes flange portions at both ends of the reel. The drive roller 210a is set as a damping shaft at the pressing position of the flange portion. When the drive roller 210a rotates, the damping shaft cooperates with the flange portion to generate a driving force that drives the reel 27 to rotate. The reel can be directly guided along the reel loading step 212 and pushed into the reel drive module 210. At this time, the reel is loaded in the reel drive module 210. The tensioning module 211 is used to tension the wire bundle between the tensioning wheel and the guide wheel.

[0065] The winding mechanism 22 includes a wire winding module 220 and a wire bundle tie module 221 disposed behind the wire winding module 220. A guide rail bracket 23 is disposed above the wire winding module 220 and the wire bundle tie module 221. A wire gripping module 24 is disposed on the guide rail bracket 23 for gripping the wire bundle wound on the wire winding module to the wire bundle tie module. A cutting blade 240 is disposed on the front side of the wire gripping module 24 for cutting and separating the wire bundle from the material strip.

[0066] The wire winding module 220 includes a turntable 220a, which is driven to rotate by a first driving mechanism 2101. The turntable 220a is provided with spaced wire winding posts 220b. The wire winding posts 220b are driven to move closer or further apart by a second driving mechanism 22102. A first wire fixing gripper 2201 is fixed on one side of the turntable 20a. The first wire fixing gripper 2201 is used to limit the position of the wire handle without obstructing the passage of the wire handle. It is used to limit the position of the wire handle when it is being wound to prevent it from moving up and down.

[0067] The cable tie module 221 includes a second cable tie fixing gripper 2202 for fixing the cable tie ends at both ends of the cable tie, a cable tie pressing gripper 221a is provided between the two second cable tie fixing grippers 2202, a cable tie feeding mechanism 221b is provided on one side of the cable tie pressing gripper 221a, and a cable tie twisting mechanism 221c is movably provided on the guide rail bracket 23.

[0068] Aligned teeth 25 are provided on both side walls at the connection between the feeding step 212 of the reel and the reel drive module 210. The teeth of the teeth 25 can be used to install the second driven roller 210c. The above structure can be used to fine adjust the position of the second driven roller 210c.

[0069] The second wire handle fixing gripper 2202 includes a limiting groove at its end, within which a flexible pressure block 2202a is disposed. The flexible pressure block 2202a contacts the wire handle to prevent damage. The tensioning module 211 includes a vertically arranged tensioning wheel bracket 211a, a first guide wheel 211b fixedly disposed at the top of the tensioning wheel bracket 211a, a longitudinally sliding tensioning wheel 211c disposed on the tensioning wheel bracket 211a, and a second guide wheel 211d disposed at the front end of the tensioning wheel bracket 211a. A first straightening wheel set 26 is provided in the automatic wire feeding device 21 and the wire feeding mechanism 22. In the above technical solution, a second straightening wheel set 27 is provided at the front end of the feeding outlet of the cable tie feeding mechanism 221b.

[0070] See Figures 6 to 12The electronic detonator sheathing and wire separating mechanism 3 includes a mounting bracket 331, an sheath cutting mechanism 32, a wire pressing mechanism 33, and a wire separating mechanism 34. The sheath cutting mechanism 32 is used to cut the outer sheath of the detonator wire, and the wire pressing mechanism 33 is used to flatten and shape the two core wires of the detonator wire so that the wire separating pin 340 of the wire separating mechanism 34 can be inserted between the two core wires to separate them.

[0071] The first mounting bracket 31 is movably mounted on the base plate 3100, and the first mounting bracket 31 is driven by the first driving module 3101.

[0072] The outer skin cutting mechanism 32 includes an upper cutting blade assembly 320 and a lower cutting blade assembly 321 disposed at the upper and lower positions of the first mounting bracket 31. The upper cutting blade assembly 320 includes a movably disposed upper cutting blade plate 320a, an upper cutting blade plate driving module 320b for pushing the upper cutting blade plate, and an upper cutting blade 320c disposed at the lower end of the upper cutting blade plate 320a. The lower cutting blade assembly 321 includes a movably disposed lower cutting blade plate 321a, a lower cutting blade plate driving module 321b for pushing the lower cutting blade plate 321a, and an upper cutting blade 320c disposed at the lower end of the upper cutting blade plate 320a. The lower cutter 321c, located at the upper end of the board, forms a cut 3200 between the upper cutter 320c and the lower cutter 321c for removing the outer sheath. The cut 3200 is formed by the upper cutter 320c and the lower cutter 321c moving closer together, thereby cutting off the outer sheath 3301 of the detonator wire 3302 that passes through the cut. After the cable sheath is cut off, the first drive module 3101 drives the first mounting bracket 31 to move back a certain distance, so that the cut section of the outer sheath at the end moves a certain distance along the cable and falls off.

[0073] The wire pressing mechanism 33 includes an upper pressing plate 330 movably disposed with the upper cutting plate 320a and a lower pressing plate 331 movably disposed with the frame. The upper pressing plate 330 is driven by an upper pressing plate driving module 332 disposed on the frame, and the lower pressing plate 331 is driven by a lower pressing plate driving module 333. After the outer sheath of the outer cable is cut by the cut 3200 and broken, the upper and lower pressing plates of the wire pressing mechanism 33 come together to flatten the two core wires.

[0074] The wire separating mechanism 34 includes a wire separating pin 340, the tip of which is located at the front end of the cut 3200, and the bottom end of which is fixed to a wire separating pin seat 341. The wire separating pin 340 is driven to move up and down by a second drive module 3102. It also includes a pin sleeve 342 sleeved over the wire separating pin 340, which is driven to move horizontally by a third drive module 3103. After the wire pressing mechanism 33 flattens the core wires, the wire separating pin 340 is driven to rise by the second drive module 3102 and inserted between the two core wires. At this point, the pin sleeve 342 is driven to move horizontally by the third drive module 3103 until the distance between the two core wires is adjusted to the required size, at which point the mechanism stops.

[0075] The first mounting bracket 31 has a waste guide plate 35 located at its rear side, which is used to receive the detonator wire sheath cut by the cut. The upper pressure plate 330 has a pin baffle 334. The pressing position of the upper pressure plate 330 and the lower pressure plate 331 against the core wire is located at the rear end of the pin baffle. The pin baffle 334 has a positioning groove 335 that provides positioning for the tip of the splitting pin.

[0076] In this structure, the blade holders 3300 of the upper cutting blade 320c and the lower cutting blade 321c are offset from each other, and mutually cooperating inclined surface structures are provided on both sides of the blade holders of the upper and lower cutting blades. Furthermore, the dividing pin 340 has inwardly recessed extension grooves 340a distributed longitudinally. In this structure, when the upper cutting blade 320c and the lower cutting blade 321c are engaged, the inclined surfaces on the blade holders 3300 cause the cutting edges on the two blade holders to be offset from each other, forming a stable cut 3200.

[0077] See Figures 13 to 16 The inner core twisting device 4 includes a sliding plate 41 and a mounting bracket 42. The sliding plate 41 is slidably disposed on the base plate 4100. A sliding plate drive module 4101 for pushing the sliding plate is disposed on one side of the sliding plate 41. The mounting bracket 42 is fixedly disposed on the sliding plate 41. Multiple sets of inner core twisting assemblies 43 are disposed on the mounting bracket 42. The inner core twisting assembly 43 includes a fixed sleeve 430 fixedly disposed on the mounting bracket 42. A rotating shaft 431 is rotatably supported on the fixed sleeve 430. One side of the rotating shaft 431 is located at the rear end face of the mounting bracket, and the other side is located at the front end face of the mounting bracket. A synchronous pulley 432 is disposed on one side of the rear end face of the mounting bracket. A synchronous belt 433 is tensioned between the multiple sets of synchronous pulleys 432, and the synchronous belt 433 is driven by a synchronous belt drive module 434.

[0078] The rotating shaft 431 is fixedly provided with a clamping mechanism 44 on one side of the front end face of the mounting bracket 42. The clamping mechanism 44 includes an upper clamping claw 440 and a lower clamping claw 441 that can be driven to perform clamping / releasing actions. Multiple sets of spaced slots 441a are provided on the lower clamping claw 441, and a positioning hole 441b is provided between two slots 441a. The upper clamping claw 440 includes inserts 440a in number corresponding to the slots 441a. A positioning post 440b that matches the position and shape of the positioning hole 441b is provided between two inserts 440a.

[0079] An end-limiting mechanism 45 is provided on one side of the clamping mechanism 44. It includes an upper end clamping block 450 and a lower end clamping block 451. The upper end clamping block 450 is movably disposed. A spring 4200 is provided at one end of the upper end clamping block to provide elastic bias. A V-groove is provided on the lower end clamping block 451. A V-shaped protrusion matching the shape of the V-groove is provided on the upper end clamping block 450. The upper end clamping block 450 is driven by the fourth drive module 4102.

[0080] When the aforementioned electronic detonator core twisting device is in use, the sliding plate drive module 4101 outputs power, causing the detonator wire to first pass through the end limiting mechanism 45 and then enter the clamping position of the clamping mechanism 44. At this time, the upper clamping claw 440 and the lower clamping claw 441 in the clamping mechanism clamp together, separating the two cores in the detonator wire on both sides of the positioning post 440b, and clamping the two separated cores. Then, the synchronous belt drive module drive 434 drives the synchronous belt pulley and drives the drive shaft. The shaft drives the clamping mechanism to twist the core wire as needed. In addition, a spring 4200 is provided at one end of the end clamping block to provide elastic bias. The spring 4200 provides elastic bias to the end clamping block 450, so that when the detonator wire is pressed against the end clamping block and the lower end clamping block, the end clamping block can provide floating clamping force to prevent damage to the locking part that may be caused by locking the end during the twisting process.

[0081] In this configuration, the two adjacent end clamping blocks 451 are fixed as a single unit. Preferably, the end clamping blocks 451 are driven by the third drive module 4103. Since detonator wires tend to sag, the above structure allows the end clamping blocks 451 to be positioned below a preset height. At this height, the detonator wire in the wire bundle transported by the carrier is initially located above the end clamping blocks 451. Then, the third drive module 4103 pushes the end clamping blocks 451 to the preset position. This avoids the potential problem of the detonator wire not being able to enter the V-groove of the end clamping block 451 when the sag is excessive.

[0082] The end injection molding device 5 is an injection molding machine. The injection molding machine is used to perform injection molding at one end of the wire handle and form an injection plug at that end. The front end of the injection plug has an extended wire from the wire handle. Specifically, the structure of forming an injection plug at the end using an injection molding machine is existing technology in the injection molding industry. Its structure and principle will not be described in detail in this embodiment.

[0083] See Figures 17 to 21 The wire box crimping device 6 includes a workbench 61, a wire box feeding mechanism 65, a pressing mechanism 66, and a discharging mechanism 67.

[0084] The upper worktable 61 is provided with a receiving cavity 610 for placing the upper and lower wire box covers. A baffle plate 62 is provided at the front of the receiving cavity 610. The baffle plate 62 includes a discharge port 620 on the left side. The bottom wall of the discharge port 620 is flush with the bottom wall of the receiving cavity 610, and the discharge port 620 allows the lower wire box cover to pass through. A pushing mechanism 63 is provided on the right side of the receiving cavity 610, and a positioning plate 64 for positioning the upper wire box cover is provided on the left side of the receiving cavity 610. The positioning plate 64 and the pushing mechanism 63 are directly opposite each other and are located on the left and right sides of the receiving cavity, respectively. Their function is to push the upper and lower wire box covers that are conveyed into the receiving cavity 610 to the positioning plate 64 for positioning by the pushing mechanism 63. At this time, the shaft part in the upper wire box cover and the shaft seat in the lower wire box cover are directly opposite each other.

[0085] The wire box feeding mechanism 65 is used to supply the upper wire box cover and the lower wire box cover. It is located on the rear side of the receiving cavity, and the outlet of the wire box feeding mechanism is located on the right side of the discharge port. The wire box feeding mechanism includes a vibrating feeding mechanism for conveying the upper wire box cover and the lower wire box cover respectively. Since the outlet of the wire box feeding mechanism is located on the right side of the discharge port, when the wire box feeding mechanism 65 conveys the upper wire box cover and the lower wire box cover, the two components are blocked by the baffle plate 62 on the front side of the receiving cavity 610, which can prevent them from leaving the receiving cavity.

[0086] The pressing mechanism 66 is disposed above the accommodating cavity 610. The pressing mechanism 66 includes an upper wire box cover pressing block 660 located above the upper wire box cover and a lower wire box cover pressing block 661 located above the lower wire box cover. A rotating shaft pressing block 662 matching the position of the rotating shaft on the lower wire box cover is provided on one side of the lower wire box cover pressing block 661. During operation, the upper wire box cover pressing block 660 is first driven to press down to position the upper wire box cover. At this time, the lower wire box cover pressing block 661 is used to position the lower wire box cover while pressing the shaft part in the upper wire box cover into the shaft seat in the lower wire box cover.

[0087] In the above structure, when the pushing mechanism 663 pushes the upper and lower wire box covers, which are conveyed into the receiving cavity 6610, to the positioning position on the positioning plate 64, the lower wire box cover and the discharge port 620 are directly opposite each other. Since the shaft portion in the upper wire box cover is bent upwards, after pressing, the upper wire box cover floats upwards under the plastic deformation force of the shaft portion, resulting in a structure where the upper wire box cover is higher than the lower wire box cover. At this time, the discharge mechanism 67 can apply a pushing force to the pressed wire box assembly, pushing the wire box assembly out of the receiving cavity 610, completing the discharge step. See also... Figure 21 The junction box assembly 21 is pushed out from the accommodating cavity 610 and enters along the track to the position below the end pressure block 640, where the end pressure block 640 presses down to press the terminals into the junction box.

[0088] The above structure greatly reduces the number of limiting components for the upper and lower wire box covers without affecting the wire box discharge after pressing. The structure is simple and the pressing efficiency is greatly improved.

[0089] The upper cable box cover pressing block 660 and the lower cable box cover pressing block 661 both include two sets of pressing feet spaced apart. The structure of the two sets of pressing feet facilitates the pressing and fixing of the upper cable box cover and the lower cable box cover, preventing them from shifting position during pressing.

It can remove the outer sheath through the structure of upper and lower cutters or other commonly used outer sheath removal structures, which will not be described in detail in this embodiment.

[0092] The automatic discharging device 8 is used to deliver the completed electronic detonators to the storage box. Its structure and principle are the same as those of commonly used discharging devices, and its structure and principle will not be described in detail in this embodiment.

[0093] Furthermore, a first detection mechanism 101 for detecting the twisted wire of the inner core is provided between the inner core twisting device 4 and the end injection molding device 5. The first detection mechanism 101 is a visual inspection mechanism, which includes functions for detecting whether the number of twisted turns in the inner core twisting device 4 and the electronic detonator outer sheath stripping and wire separating mechanism 3 meets the requirements, whether the wire separating size is in place, and whether the wire stripping is in place, etc., to ensure that the above parameters meet the requirements before being sent into the end injection molding device 5, so as to avoid the problem of injection plug falling off easily due to the above parameters not being in place.

[0094] Furthermore, a second inspection mechanism 102 is provided between the inner core stripping and cutting device and the discharge device 8. The second inspection mechanism includes electronic detonator electrical continuity detection and electronic detonator visual inspection. The electrical continuity detection is used to check whether the electronic detonator cable is conductive, and the visual inspection is used to check whether the injection head shape is qualified and whether the inner core is cut in place. With the aforementioned first inspection mechanism 101 and second inspection mechanism 102, defective products are basically eliminated, and the product qualification rate is greatly improved.

[0095] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
