[0003] However, in the production of electronic detonators, the process of attaching the sleeve to the electronic detonator is still manually operated due to the lack of an automated production process to replace the inconsistent product quality. This method of operation involves operators directly contacting hazardous agents, resulting in inherently poor safety and outdated production technology.

[0004] On the other hand, in order to achieve automated production of electronic detonators, after the sleeve is put on manually, the entire sheet of electronic detonator chips still needs to be placed one by one onto the chip assembly mold of the assembly line. This method has low production efficiency and seriously restricts the production capacity of the electronic detonator assembly line. Summary of the Invention

[0028] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1As shown, an automatic heat-shrink tubing fitting device for electronic detonators according to the present invention includes a workbench 2, a continuous circulating transport channel 5, a finished product collection channel 14, and a waste product collection channel 1. The continuous circulating transport channel 5 is located in the middle of the workbench 2, and multiple sets of chip heat-shrink molds 13 are arranged on the circulating transport channel 5. The chip heat-shrink molds 13 are used for heat-shrinking the chip detonator tip end sleeve. The finished product collection channel 14 is located in the lower right corner of the workbench 2, symmetrically arranged on both sides of the circulating transport channel 5 with the waste product collection channel 1. Multiple chip assembly molds 15 for electronic detonator assembly lines are arranged side by side on the finished product collection channel 14. All channels use synchronous belt conveyors, which ensure stable and reliable transmission and controllable speed.

[0030] At the front end of the circulating transmission channel 5, from the middle to the left, there are a chip mold loading station 3 and a material sorting and inspection station. At the material sorting and inspection station, there is a material sorting and inspection mechanism 4. At the rear end of the circulating transmission channel 5, from left to right, there are a heat shrink tubing fixed length cutting mechanism 7, a flipping sleeve mechanism 6, a heat shrink correction mechanism 8, a dual-station inspection mechanism 9, an inspection marking mechanism 10, an ear piece removal mechanism 11, and a material unloading and tray loading mechanism 12.

[0031] like Figure 2 As shown, the heat shrink tubing fixed-length cutting mechanism includes, from left to right, a wire feeding frame 701, a first support 703, a second support 707, and an I-beam support 706. The wire feeding frame 701 is equipped with multiple rolls of tubing for automatic feeding. Two sets of transverse movement cylinders 702 are respectively installed on the sides of the first support 703 and the second support 707. A gripper cylinder 704 is vertically mounted on the drive end of the transverse movement cylinder 702. The two movable ends of the gripper cylinder 704 are respectively connected to vertically staggered... The parallel grooves 705, when clamped by the gripper cylinder 704, clamp the sleeve by being staggered vertically. With the help of the transverse cylinder 702, the sleeve can be moved, realizing the fixed-length conveying of the heat shrink tubing. In order to ensure that the heat shrink tubing is neatly arranged during the conveying process, a sleeve guide block 708 and a grid plate 709 are set in the middle of the second support to guide the heat shrink tubing and reliably separate the heat shrink tubing conveyed side by side at equal intervals.

[0032] like Figure 3As shown, the heat shrink tubing fixed-length cutting mechanism has a tubing cutting unit at the front end of the second bracket, including a tubing cutting cylinder 710, a sliding plate 711, and a cutting blade 715. The tubing cutting cylinder 710 is installed at the front end of the second bracket 707, and its extended end is floatingly connected to the sliding plate 711. The connection between the second bracket 707 and the sliding plate 711 is provided with a first sliding groove 717 to facilitate the sliding of the sliding plate 711. Two sets of cutting blades 715 are symmetrically arranged at the front end of the sliding plate 711, and the left and right ends of the cutting blades 715 are embedded in the second sliding groove of the second bracket 707. The sliding plate 711 is provided with four sets of inclined grooves 713 with opposite heads and two sets of straight grooves 712. The rear end of the cutting blade 715 is provided with a sliding shaft 716, which can slide in the four sets of inclined grooves 713 of the sliding plate 711. By actuating the sleeve cutting cylinder 710 and with the help of the inclined groove 713, the cutting blade 715 can move up and down along a fixed track to cut the sleeve.

[0033] like Figure 4 As shown, the flip-tube mechanism is located at the front end of the heat shrink tubing fixed-length cutting mechanism, including a third support 601 and a fourth support 610, with the third support 601 and the fourth support 610 positioned on both sides of the flow channel; two rotary cylinders 602 are symmetrically arranged at both ends of the third support 601, and a U-shaped connecting plate 603 is provided at the swing end of the rotary cylinder, on which two sets of tube-sleeving cylinders 604 are arranged, with multiple guide rods 605 connected to the end of each set of tube-sleeving cylinders 604, on which buffer springs 606 are provided to ensure that the chip tip is not damaged during the tube-sleeving process; a connecting plate 607 is fixed at the end of the guide rod, on which multiple sets of tube-sleeving clamps 608 are arranged side by side.

[0034] First, the heat shrink tubing is transported to the tubing carrying device 608 of the flip-tube mechanism by the combined action of the transverse cylinder 702 and the gripper cylinder 704 on the first bracket 703 and the second bracket 707 of the heat shrink tubing fixed-length cutting mechanism. Then, the cutting blade 715 of the heat shrink tubing fixed-length cutting mechanism cuts the heat shrink tubing to the fixed length, thus fitting the heat shrink tubing into the tubing clamp 608. At the same time, the flip-tube mechanism rotates 180 degrees using the rotary cylinder 602, and the tubing cylinder 604 extends to fit the heat shrink tubing in the tubing carrying device onto the tip of the entire chip.

[0035] To ensure that the chips do not become misaligned during the chip sleeve process, a fourth bracket 610 is provided on the right side of the third bracket 601, and an ejector cylinder 609 and a pressure plate 611 are provided on the top of the fourth bracket 610 to fix the chips on the board during the sleeve process.

[0036] Meanwhile, multiple sets of symmetrical fiber optic sensors 719 are respectively installed on the first support 703, the second support 707, and the I-shaped support 706 of the heat shrink tubing fixed-length cutting mechanism to perform multi-position detection of the tubing conveying channel; and multiple sets of symmetrical fiber optic sensors 718 are installed on the tubing cutting end of the second support 707 to detect the presence or absence of tubing; during the tubing cutting process, if it is detected that a tubing is not being fed in time, the tubing flipping mechanism will not connect with the heat shrink tubing fixed-length cutting mechanism, and the cut tubing will fall directly into the waste collection box 714 below, and an alarm will be triggered to the operator to check the cause of the tubing shortage.

[0037] like Figure 5 As shown, the heat shrinking correction mechanism includes a beveled limiting strip 801 and a support frame 804. A hot air blower 803 is mounted on the support frame 804, and a protective cover 802 is mounted on its exterior to achieve heat shrinking of the sleeve. The beveled limiting strip 801 can guide and constrain the axial position of the sleeve fitted into the chip during the transfer of the chip heat shrinking mold 13, ensuring the consistency of the axial length of the sleeve.

[0038] To ensure a high yield rate, the electrical performance of the heat-shrinked chip circuit board needs to be tested, as does the appearance of the heat-shrinked tubing. A dual-station inspection mechanism is located on the right side of the heat-shrinking calibration mechanism. Figure 6 As shown. The dual-station inspection mechanism includes a fifth support 901 and a sixth support 906. The fifth support 901 is equipped with a transverse cylinder 903, and an industrial camera 902 is connected to the moving end of the transverse cylinder 903. A light source 904 is installed at the lower end of the transverse cylinder 903 to perform appearance inspection after the heat shrink tubing has been heat-shrinked. The sixth support 906 is equipped with a vertical lifting cylinder 905, and an L-shaped plate 907 is floatingly connected to its driving end. The L-shaped plate 907 is equipped with multiple detection probes 908 to perform electrical performance testing of the entire board of chips.

[0039] like Figure 7As shown, the detection and marking mechanism includes a horizontal traverse module 1010. An L-shaped bracket 1001 is positioned above the traverse module 1010. The front end of the L-shaped bracket 1001 is connected to a marking mounting plate 1005 via a parallel slide rail 1006. The sliding power of the marking mounting plate 1005 is provided by a misalignment cylinder 1007. Multiple marking cylinders 1002 are arranged side-by-side at the front end of the marking mounting plate 1005. The floating end of each marking cylinder 1002 is connected to a marking mounting seat 1003, where one end of a marking fluorescent pen 1009 is installed. For ease of guidance and positioning, multiple mounting seat grooves 1004 and fluorescent pen grooves 1008 are arranged parallel to each other on the marking mounting plate 1005. When the dual-station detection mechanism detects defective products, the fluorescent pen 1009 in the detection and marking mechanism can mark the defective chips on the entire board individually or in multiples simultaneously, facilitating subsequent manual identification and judgment.

[0040] like Figure 8 As shown, the ear piece removal mechanism includes a seventh bracket 1101, the end face of which is provided with a lifting cylinder 1102 and a parallel guide rail 1104; an L-shaped sliding plate 1105 is provided on the sliding end of the parallel guide rail 1104; two cutting cylinders 1103 are provided on the end face of the L-shaped sliding plate 1105, and an ear piece cutting blade 1107 is connected to its driving end; a horizontal pressure plate 1106 is connected to the bottom end of the L-shaped sliding plate 1105, and rectangular grooves are evenly distributed on the horizontal pressure plate 1106. When the qualified products after inspection are transferred to the ear piece removal mechanism, the lifting cylinder 1102 drives the L-shaped sliding plate 1105 to move down, and uses the rectangular groove of the horizontal pressure plate 1106 to fix each chip in the whole board of chips; then the cutting cylinder 1103 drives the ear piece cutting blade 1107 to move down, peeling the ear piece from the whole board of chips, so that each chip in the whole board of chips becomes an independent chip, which facilitates the subsequent automatic assembly production of single chips; the cut ear pieces fall automatically into the waste material collection box 1108, and are manually cleaned after a shift of production.

[0041] like Figure 9 As shown, the unloading and loading mechanism includes a second transverse module 1201. Two slide cylinders 1204 are symmetrically mounted on the slider of the transverse module 1201 via a robotic arm mounting plate 1202. The extended end of each slide cylinder is connected to two sets of vacuum suction cups 1203. One set is used to load qualified electronic detonator chips into the chip assembly mold in the finished product collection channel in one go, while the other set of vacuum suction cups removes unqualified entire boards of chips into the waste collection channel.

[0042] The working principle of this invention is as follows:

[0043] 1) After the equipment is started, the electronic detonator chips that have been dipped in the chemical are manually placed into the chip heat shrink mold 13 through the feeding station;

[0044] 2) Clicking the button will automatically transfer the chip heat shrink mold 13 to the material distribution and detection mechanism 4. The material distribution and detection mechanism 4 will detect the incoming material through fiber optic sensors to determine whether there is a shortage of material. If the chip heat shrink mold 13 is short of material, the equipment will alarm and the product will be manually added into the chip heat shrink mold. The alarm will then be deactivated.

[0045] 3) The chip heat shrink mold 13 is transferred to the sleeve station. The sleeve cylinder 604 in the flip sleeve mechanism 6 drives the sleeve clamp 608 to extend. At the same time, the heat shrink tube fixed length cutting mechanism 7 feeds the heat shrink tube into the sleeve clamp 608 according to the specified length and cuts it automatically. In order to ensure that each product of the whole board of chips is sleeved at the same time, multiple fiber optic sensors 717 are set in the heat shrink tube fixed length cutting mechanism 7 to determine whether each heat shrink tube conveying channel is short of material. When a material shortage occurs, the equipment alarms, the sleeve cylinder in the flip sleeve mechanism is in the retracted state, and the cut sleeve automatically falls into the waste collection box 714.

[0046] 4) Next, the heat shrinking mechanism 8 corrects the position of the sleeves of the entire board of chips and heat shrinks the sleeves to the specified state.

[0047] 5) In order to ensure the yield rate of finished products, a dual-station inspection mechanism 9 and an inspection marking mechanism 10 are set up at the next station after the calibration heat shrinking mechanism 8. The dual-station inspection mechanism 9 uses an electrical performance tester and an industrial camera to inspect the electrical performance of the whole board chip and the appearance of the heat shrink tubing respectively. For the defective products generated during inspection, the fluorescent pen 1009 carried in the inspection marking mechanism 10 is used to mark them.

[0048] 6) Products that pass the inspection are transferred to the ear unloading station, where the ear unloading mechanism 11 removes the ear pieces from the entire board of chips, making each chip an independent unit; however, for the entire board of chips that fail the inspection, the ear pieces are not removed.

[0049] Finally, the unloading and traying mechanism 12 automatically trays the chips completed by each sleeve onto the chip assembly mold 15 in the finished product collection channel 14, preparing for the subsequent automatic assembly of electronic detonators; for the whole board of chips that fail the inspection, they are automatically loaded into the waste collection channel 1, where they are identified and discarded by personnel.
