Description

Technical Field

[0001] The utility model relates to the field of blasting, in particular to a device for detecting and rejecting waste used in detonator production. Background Art

[0002] In the process of demolishing existing construction sites or mining mountains, in order to improve efficiency, people usually use fixed-point blasting to speed up demolition or mining. The core of blasting, in addition to the fixed position and quality of explosives, is to ensure that there will be no accidental injuries during detonation. Therefore, when blasting, people usually use detonators to time or remotely detonate explosives. With the continuous advancement of technology, the development of detonators is gradually moving towards electronicization. In order to ensure that detonators can be used normally, quality inspection is usually carried out during the production process of detonators to eliminate waste products, and the overall quality of the detonators is measured after the detonator processing is completed to ensure that there will be no missed processing.

[0003] In order to batch test a large number of detonators, existing detonator production inspection and rejection equipment usually uses automated equipment to reduce the number of inspection steps and save labor. For example, a detonator conveyor device is installed on both sides of the weight detection device, and the detonators are transported by a conveyor belt. The detonators are then transferred by a grabbing mechanism for measurement operations, and the waste is transported to the recycling area using a rejection conveyor device.

[0004] The inspection process of the existing weight detection device is usually to use a grabbing mechanism to grab the detonator, then directly place the detonator on the inspection table of the weight detection device, and then use the relevant mechanical structure to put it into different placement areas. During the transfer process, there is no corresponding protection. For example, a quality inspection device for electronic detonators with application number 202211087376.1 is shown. The measured detonators are directly classified through a slope under the action of gravity. This unprotected measuring device is very likely to cause secondary failures of the detonators during the transfer process, or even cause explosions. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing detection and rejection equipment for detonator production has no corresponding safety protection during the measurement and transportation process, which makes the detonators very likely to malfunction due to collision and rolling during the transportation process.

[0006] To solve the above technical problems, the utility model provides a technical scheme for: a detection and rejection equipment for detonator production, including weight detection device, both sides of weight detection device are equipped with detonator conveying device, one side of detonator conveying device is equipped with grabbing mechanism, one side of weight detection device is equipped with rejection conveying device, the top of weight detection device is equipped with automatic positioning mechanism, automatic positioning mechanism includes V type fixed clamp for clamping detonator outer wall upper end and lower end both sides, pressure sensing rod located detonator bottom surface and limiting shell for limiting pressure sensing rod translation direction, pressure sensing rod is connected with one side top surface of V type fixed clamp through auxiliary linkage rod.

[0007] As an improvement, the limiting shell is composed of two detachable half shells, the two half shells of the limiting shell are connected through a pin structure, and the pin connecting the limiting shell passes through the side wall of the V-shaped fixed clamp.

[0008] As an improvement, the side wall of the V-shaped fixed clamp passes through the side of the limiting shell.

[0009] As an improvement, the pressure sensing rod and the V-shaped fixed clamp are connected on both sides of the auxiliary linkage rod through a pin.

[0010] As an improvement, the bottom of the weight detection device is provided with a base, and the inside of the base is provided with a control host for controlling the weight detection device, the detonator conveying device, the grabbing mechanism and the rejection conveying device.

[0011] As an improvement, the weight detection device, the detonator conveying device, the grabbing mechanism and the rejection conveying device are connected with the control host through data lines.

[0012] As an improvement, the height of the weight detection device is lower than that of the detonator conveying device.

[0013] As an improvement, the top of the detonator conveying device and the rejection conveying device is provided with a detonator positioning groove.

[0014] As an improvement, the grabbing mechanism includes a four-axis mobile mechanical arm and a mechanical claw at the output end of the four-axis mobile mechanical arm.

[0015] As an improvement, the limiting shell is connected with the measuring surface of the weight detection device through sealing glue.

[0016] The advantages of the present invention over the prior art are that, when measuring detonators, the device clamps the falling detonator through an automatic positioning structure formed by a pressure sensing rod and a V-shaped fixing clamp, thereby ensuring the stability of its center line, facilitating secondary grasping by a grasping mechanism, and ensuring that its position does not change significantly; after the measurement is completed, the detonator is directly arranged again by the grasping mechanism into the detonator positioning slot of a waste rejection conveying device or a detonator conveying device, ensuring that the detonator will not have secondary failures due to collision or rolling during transportation, and ensuring that no defective products will appear in the finished product.

DETAILED DESCRIPTION

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] As the instruction manual Figure 1 、 2As shown, it includes a weight detection device 1, detonator conveying devices 2 are provided on both sides of the weight detection device 1, a grabbing mechanism 3 is provided on one side of the detonator conveying device 2, and the grabbing mechanism 3 includes a four-axis mobile mechanical arm 31 and a mechanical claw 32 located at the output end of the four-axis mobile mechanical arm 31, a waste rejection conveying device 4 is provided on one side of the weight detection device 1, an automatic positioning mechanism 5 is provided above the weight detection device 1, and a base 6 is provided below the weight detection device 1. A control host 7 for controlling the weight detection device 1, the detonator conveying device 2, the grabbing mechanism 3 and the waste rejection conveying device 4 is provided inside the base 6. The weight detection device 1, the detonator conveying device 2, the grabbing mechanism 3 and the waste rejection conveying device 4 are all connected to the control host 7 through a data cable, and the detonator conveying device 2 is respectively installed on the left and right sides of the weight detection device 1. , the grabbing mechanism 3 is installed in front of the weight detection device 1, and the waste rejection conveying device 4 is installed behind the weight detection device 1; the base 6 is placed under the weight detection device 1 and the two are fixed with screws; the control host 7 is placed in the cavity inside the base 6, and the weight detection device 1, the detonator conveying device 2, the grabbing mechanism 3 and the waste rejection conveying device 4 are connected to the signal interface of the control host 7 using a data cable; the automatic positioning mechanism 5 is pasted on the measuring surface of the weight detection device 1 with sealant, and it is noted that the center line direction of the automatic positioning mechanism 5 is the same as the direction of the grabbing point of the detonator conveying device 2 (during installation, it is necessary to note that the height of the weight detection device 1 is lower than the detonator conveying device 2 to ensure that the four-axis mobile robot 31 of the grabbing mechanism 3 will not hit the weight detection device 1 with the longitudinal axis during the movement to the waste rejection conveying device 4).

[0025] The four-axis mobile robotic arm 31 includes a transverse axis for horizontal movement between the two detonator conveying devices, a height axis for adjusting the height of the weight detection device 1 and the detonator conveying device 2, a rotation axis for adjusting the clamping direction of the automatic positioning mechanism 5, and a longitudinal axis of the waste rejection conveying device 4 located opposite to the grasping mechanism 3. The mechanical claw 32 is installed on the rotation axis.

[0026] Detonator positioning grooves 21 are provided above the detonator conveying device 2 and the waste rejection conveying device 4. The detonator positioning grooves 21 facilitate the fixation of the detonators and ensure the accuracy of their positions, so that the grasping mechanism 3 can better grasp the detonators.

[0027] As the instruction manual Figure 2 、 3As shown in FIG4 , the automatic positioning mechanism 5 includes a V-shaped fixing clamp 51 for clamping the upper and lower ends of the outer wall of the detonator, a pressure sensing rod 52 located on the bottom surface of the detonator, and a limiting shell 53 for limiting the translation direction of the pressure sensing rod 52. The pressure sensing rod 52 is connected to the top surface of one side of the V-shaped fixing clamp 51 through an auxiliary linkage rod 54. The limiting shell 53 is composed of two detachable half shells. The two half shells of the limiting shell 53 are connected by a pin structure. The pin connecting the limiting shell 53 passes through the V-shaped fixing The side wall of the clip 51, the side wall of the V-shaped fixing clip 51 passes through the side of the limit shell 53, the pressure sensing rod 52 and the V-shaped fixing clip 51 are connected to the two sides of the auxiliary linkage rod 54 by pins, and the limit shell 53 is connected to the measuring surface of the weight detection device 1 by sealant. The edge pin holes of the bottom surfaces of the two V-shaped fixing clips 51 are respectively aligned with the pin holes on one side of the two auxiliary linkage rods 54. After inserting the pins to connect, the pin holes at the other ends of the two auxiliary linkage rods 54 are aligned with the pin holes on the bottom surface of the pressure sensing rod 52. Insert pins on both sides for fixing, clamp the outer wall of the pressure sensing rod 52 into the central slot of the half shell of the limiting shell 53, put the pin hole at the corner of the V-shaped fixing clip 51 on the pin of the half shell of the limiting shell 53 for fixing, and put the pin hole of the other half shell on the pin on this side for fixing, and finally use sealing glue to stick the bottom surface of the limiting shell 53 to the measuring surface of the weight detection device 1 for fixing. Note that the opening direction of the V-shaped fixing clips 51 inside the two limiting shells 53 is the same as the direction of the rotation axis (the direction of the limiting shell 53 is the same as the direction of the rotation axis). There are through grooves on the left and right sides, and the top end of the limit shell 53 has a sliding groove for the two V-shaped fixing clips 51 to be combined. After the automatic positioning mechanism 5 is assembled, under normal conditions, the weight of the outer part of the V-shaped fixing clip 51 is greater than the weight of the pressure sensing rod 52, so that the V-shaped fixing clip 51 is a normally open structure under normal conditions. Only when the pressure sensing rod 52 is subjected to the pressure of the detonator will the V-shaped fixing clip 51 be closed. When the mechanical claw 32 puts down the detonator, the mechanical claw 32 is located between the automatic positioning mechanism 5, and the same is true when grabbing).

[0028] When the utility model is implemented, Figure 5As shown, the detonator to be tested is placed in the detonator positioning slot 21 of the detonator conveying device 2 at the feed end. When it rotates to the grabbing point, the four-axis mobile mechanical arm 31 is started to grab the detonator at that point. After the grabbing is completed, the height axis of the four-axis mobile mechanical arm 31 is raised and then rotated 90 degrees so that its center line is in the same direction as the center direction of the circle of the automatic positioning mechanism 5. The horizontal axis of the four-axis mobile mechanical arm 31 is translated so that it is located above the weight detection device 1. The height axis of the four-axis mobile mechanical arm 31 is then translated so that it is located above the pressure sensing rod 52. When the weight detection device 1 detects the weight, the mechanical claw 32 is released to allow the detonator to fall between the V-shaped fixing clamps 51. After the pressure sensing rod 52 is pressed by the weight, it moves downward. Driven by the auxiliary linkage rod 54, the open end formed by the V-shaped fixing clamp 51 is closed, and the detonator is clamped at the same time to prevent it from moving, thereby ensuring the stability of the center line of the detonator. After the weight detection device 1 measures the result, the normal detonator will be grabbed and translated to the detonator positioning slot 21 of the detonator conveying device 2 at the discharge end by the four-axis mobile robot 31. Similarly, if the weight of the detonator is abnormal, it will be moved to the detonator positioning slot 21 of the waste rejection conveying device 4. After completing a round of determination, the detonator positioning slot 21 at the feeding end detonator conveying device 2 and the detonator positioning slot 21 at the waste rejection conveying device 4 are both moved clockwise by a fixed position, and the detonator positioning slot 21 at the feeding end detonator conveying device 2 is moved counterclockwise by a fixed position for the next round of detection.

[0029] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
