[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining this application and are not intended to limit this application. The methods used in this utility model are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0025] Depend on Figure 1 、 Figure 2 As shown, the utility model provides a deep hole dispensing machine, which includes a dispensing pump and a dispensing mechanism 24. The dispensing mechanism 24 includes a mounting plate 1 and multiple dispensing heads 2. The multiple dispensing heads 2 are connected and arranged on the mounting plate 1. Each dispensing head 2 is directly connected to the dispensing pump through a separate pipeline 3.

[0026] In the present invention, each dispensing head 2 is directly connected to the dispensing pump through a separate pipeline 3, and does not use transition components such as the cylinder chamber in the prior art. This fundamentally avoids the technical problems in the prior art that the cylinder chamber is easily set up, which makes it very easy for the glue to flow unsmoothly or even be blocked, and the glue cannot be accurately and quantitatively pressed out of the dispensing head 2 through the piston movement inside the dispensing valve, thereby ensuring that the dispensing head 2 can output the glue smoothly.

[0027] According to actual needs, in order to facilitate the adjustment and movement of the dispensing head 2 front and back, left and right, and up and down, Figure 2 、 Figure 3 As shown, the dispensing mechanism 24 preferably also includes a servo motor 4 and a transverse linear module 5. The drive end of the servo motor 4 is connected to the transverse linear module 5. The servo motor 4 and the transverse linear module 5 are mounted on the dispensing machine upper plate 6, and the dispensing machine upper plate 6 is connected to the dispensing machine back plate 7. The transverse linear module 5 is connected to the dispensing cylinder 9 via a left-right adjustment mechanism 8, and the dispensing cylinder 9 is connected to the mounting plate 1. Before use, the dispensing head 2 is adjusted left and right by the left-right adjustment mechanism 8, and the dispensing head 2 is positioned in the left-right direction. During use, the dispensing head 2 is moved forward and backward by the transverse linear module 5, and moved up and down by the dispensing cylinder 9.

[0028] Depend on Figure 3 As shown, the dispensing mechanism 24 also preferably includes a waste liquid discharge device, which is provided with a waste liquid discharge tank 10, which is connected to a waste liquid discharge trough 11, and the waste liquid discharge trough 11 is arranged below the dispensing head 2; the waste liquid discharge tank 10 is connected to the waste liquid barrel 13 through a waste liquid discharge pipe 12. During use, when the dispensing head 2 is stopped for more than 3 minutes, the dispensing head 2 needs to discharge a small amount of glue before dispensing to ensure that the dispensing head can output the glue smoothly and accurately and avoid inaccurate output; the glue discharged in advance by the dispensing head 2 is discharged into the waste liquid discharge tank 10 through the waste liquid discharge trough 11, and then flows into the waste liquid barrel 13 through the waste liquid discharge pipe 12, completing the collection of waste liquid and reducing the pollution of the glue to the surrounding environment.

[0029] Depend on Figure 3 As shown, the waste liquid tank 10 is preferably further provided with an anti-solidification groove 39, which is arranged below the dispensing head 2. When in use, water is placed in the anti-solidification groove 39; when the dispensing head 2 is stopped for too long, the dispensing head 2 is placed in the water in the anti-solidification groove 39 to ensure that the dispensing head 2 is not exposed to the air for a long time and does not become clogged.

[0030] In order to facilitate the transportation and positioning of the deep hole tray 16, Figure 1 、 Figure 2As shown, the dispensing machine preferably also includes a conveying device 25, which is arranged on one side of the dispensing mechanism 24; the conveying device 25 includes a conveyor belt rack 14, and a conveyor belt 15 installed on the conveyor belt rack 14, a deep-hole material tray 16 is placed on the conveyor belt 15, and the conveyor belt rack 14 is installed with a positioning device 26 for positioning the deep-hole material tray 16.

[0031] The positioning device 26 can be the existing technology, or the structure described in the present utility model: Figure 2 As shown, positioning device 26 preferably includes two relatively spaced positioning cylinders 17, one mounted on either side of conveyor belt 15 and connected to conveyor belt frame 14. During use, conveyor belt 15 transports deep-hole material tray 16 containing detonator shells 27 to a designated position between two positioning cylinders 17. The two positioning cylinders 17 are then activated to coordinately position deep-hole material tray 16.

[0032] In order to further accurately position the deep hole tray 16, Figure 4 As shown, the piston rod head of the positioning cylinder 17 is also connected to a push plate 18, and a V-shaped bayonet 19 is provided at the front end of the push plate 18. Positioning rollers 20 are respectively provided at both ends of the V-shaped bayonet 19. The positioning rollers 20 are rotatably connected to the push plate 18. During use, after the deep-hole material tray 16 reaches the above-mentioned specified position, if there is a position error, the positioning rollers 20 will first contact the plate body of the deep-hole material tray 16 during the extension process of the piston rod of the positioning cylinder 17. During the continued advancement process, the positioning rollers 20 are used to push the deep-hole material tray 16, fine-tuning its position. Finally, the V-shaped bayonet 19 engages with the vertical corners of the deep-hole material tray 16, completing the precise positioning of the deep-hole material tray 16. In addition, the two positioning cylinders 17 can be respectively one with high thrust and one with low thrust. The two positioning cylinders 17 thrust in opposite directions to ensure that the deep-hole material tray 16 always stays on the side of the positioning cylinder 17 with low thrust and is accurately positioned.

[0033] Depend on Figure 1 As shown, the dispensing pump is preferably installed in a dispensing pump cabinet 21 (the dispensing pump diagram is omitted), and the dispensing pump is connected to a liquid storage barrel 23 through a liquid infusion tube 22. During use, glue is placed in the liquid storage barrel 23 to supply glue to the dispensing pump.

[0034] The above-mentioned horizontal linear module 5 can be the existing technology, or the structure described in the present utility model: Figure 3As shown, the horizontal linear module 5 includes a first slide 28, a lead screw, and a first slider 29. A lead screw nut is fixedly connected inside the first slider 29, and the lead screw and the lead screw nut are matched and connected. The first slide 28 is provided with a first slide rail, and the first slider 29 is slidably connected to the first slide rail. The first slide 28 is fixedly connected to the upper plate 6 of the dispensing machine; the driving end of the servo motor 4 is connected to the lead screw; the first slider 29 is connected to the left and right adjustment mechanism 8, and the first slider 29 is connected to the left and right adjustment mechanism 8. Figure 2 When in use, the forward or reverse rotation of the servo motor 4 causes the first slider 29 and the left and right adjustment mechanism 8 to move forward and backward in the lateral direction relative to the first slide 28 through the coordinated lead screw and lead screw nut, ultimately achieving the forward and backward movement of the dispensing head 2.

[0035] The left and right adjustment mechanism 8 can be the existing technology, or the structure described in the present utility model: Figure 3 As shown, the left-right adjustment mechanism 8 includes a second slide 30, a screw rod 31, a second slider 32, and a support connecting plate 33. A screw nut is fixedly connected to the second slider 32, and the screw rod 31 is matched with the screw nut. The second slide 30 is provided with a second slide rail, and the second slider 32 is slidably connected to the second slide rail. The second slider 32 is fixedly connected to the dispensing cylinder 9; the second slide 30 is fixedly connected to the support connecting plate 33, and the support connecting plate 33 is fixedly connected to the first slide 29. During use, by rotating the screw rod 31, the screw rod 31 and the screw nut cooperate with each other, so that the second slider 32 and the dispensing cylinder 9 can move left and right relative to the second slide 30, and finally the dispensing head 2 can move left and right.

[0036] Depend on Figure 3 、 Figure 5 As shown, a first liquid level sensor 34 is preferably installed in the waste liquid barrel 13. During use, when the waste liquid in the waste liquid barrel 13 reaches a preset liquid level, the first liquid level sensor 34 generates a sensing signal and transmits the sensing signal to the intelligent control device 35 via a control circuit. The intelligent control device 35 is an intelligent controller, which can be a PLC (Programmable Logic Controller). After receiving the sensing signal, the intelligent control device 35 sends a command to the first alarm 36 via the control circuit. After receiving the command, the first alarm 36 sounds an alarm to alert the operator.

[0037] Depend on Figure 1 、 Figure 5As shown, a second liquid level sensor 37 is preferably installed in the liquid storage barrel 23. During use, when the glue liquid in the liquid storage barrel 23 decreases to a preset liquid level, the second liquid level sensor 37 generates a sensing signal and transmits the sensing signal to the intelligent control device 35 via a control circuit. The intelligent control device 35 is an intelligent controller, which can be a PLC (Programmable Logic Controller). After receiving the sensing signal, the intelligent control device 35 sends a command to the second alarm 38 via the control circuit. After receiving the command, the second alarm 38 sounds an alarm to alert the operator.

[0038] The working process of the present utility model is as follows: after the initialization is completed, the dispensing cylinder 9 moves upward, and the dispensing head 2 moves out of the anti-curing groove 39. At this time, the pipeline 3 is already filled with glue. When the deep hole material tray 16 containing the detonator shell 27 is in place, the two positioning cylinders 17 of the positioning device 26 act simultaneously to position the deep hole material tray 16. The servo motor 4 drives the horizontal linear module 5 to move forward. When it reaches directly above the deep hole material tray 16, the servo motor 4 stops working; then, the dispensing cylinder 9 drives the mounting plate 1 to move downward, so that the dispensing head 2 is inserted into the deep hole of the first group of detonator shells 27, and the dispensing pump in the glue pump cabinet starts to apply glue. After applying glue, the dispensing head 2 moves forward slightly, and the dispensing head 2 sticks to the wall of the deep hole of the detonator shell 27. Then, the dispensing cylinder 9 moves upward, and the dispensing head 2 moves out of the deep hole of the detonator shell 27. The servo motor 4 is started to drive the transverse linear module 5 to continue moving forward to dispense glue to the deep holes of the second group of detonator shells 27 until the last group of glue pumps completes the deep hole dispensing. The servo motor 4 drives the transverse linear module 5 back to the initial position.

[0039] It should be noted that:

[0040] (1) Figure 1 The pipeline 3 shown is a structural diagram, which is a collection of all the small pipelines running side by side. These small pipelines exist separately and are isolated from each other. Each small pipeline is connected to a dispensing head and a dispensing pump. The dispensing pump controls the flow of glue in each small pipeline to ensure that the dispensing head 2 outputs glue smoothly and accurately.

[0041] (2) There are usually more than 20 dispensing heads 2 to improve production efficiency.
