Description

Technical Field

[0001] This utility model relates to the field of pyrotechnics technology, and in particular to a sprue cutting tool, cutting assembly, and cutting device for the production of electronic detonator control modules. Background Technology

[0002] Currently, electronic detonators are widely used in tunnel excavation, hazard removal blasting, demolition blasting, rock and ore separation, open-pit mine blasting, and other applications. The electronic detonator control module is the initiation control part of the electronic detonator, and its stability directly affects the stability of the electronic detonator. The electronic detonator control module mainly includes integrated control chips, ignition components, energy storage capacitors, and other electronic components mounted on a circuit board. In addition, during the production process, the electronic detonator control module needs to be sealed with adhesive to protect the electronic components mounted on the circuit board, giving them moisture-proof and dust-proof functions.

[0003] Furthermore, in order to improve the protection of electronic components on the electronic detonator mold, low-pressure injection molding is generally used in the prior art to reduce the impact of the injection molding process on the product and avoid product damage. Before sealing the electronic detonator control module, the electronic detonator control module needs to be placed in the cavity of the injection mold for fixation, and then molten glue is injected into the cavity from the glue inlet provided at one end of the cavity length direction to achieve sealing.

[0004] However, by injecting molten adhesive into the cavity through a sprue located at one end along the length of the cavity, electronic components near the sprue often need to withstand significant impact pressure, which can easily lead to damage to these components.

[0005] To address the technical problem of electronic components being easily damaged due to the need to withstand significant impact pressure, the applicant's researchers proposed a double-sided encapsulation method. However, when using this method to encapsulate an electronic detonator control module, two lateral sprue sections are connected to the outer side of the encapsulated body formed around the encapsulated module. The removal of these lateral sprue sections is primarily done manually, and there are no suitable cutting tools available in the prior art. Therefore, there is an urgent need for a sprue cutting tool that facilitates the removal of the lateral sprue sections connected to the outer side of the encapsulated body formed around the encapsulated electronic detonator control module. Summary of the Invention

[0006] The purpose of this utility model is to overcome at least one deficiency of the prior art and provide a sprue cutting tool for the production of electronic detonator control modules, which is beneficial for cutting the lateral sprue material connected to the outer side of the sealant body formed on the outer periphery of the sealed electronic detonator control module; in addition, a sprue cutting assembly and a sprue cutting device for the production of electronic detonator control modules are also provided.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: According to one aspect of this application, a sprue cutting tool for the production of electronic detonator control modules is provided, comprising: A connecting body, wherein the connecting body is a long plate-shaped structure; A punching protrusion 1 is connected to the first end of the connecting body in the length direction and extends out of the connecting body in the first side in the width direction of the connecting body. The second punching protrusion is connected to the first end of the connecting body in the length direction, opposite to the first punching protrusion, and extends out of the connecting body in the second side in the width direction of the connecting body.

[0008] The beneficial effects of this utility model are as follows: In this embodiment, the first punching protrusion is connected to the first end of the connecting body along its length, and the second punching protrusion is connected to the first end of the connecting body along its length, so that the first punching protrusion and the second punching protrusion are connected to the two sides of the first end of the connecting body, respectively, back to back; when the sprue cutting tool in this embodiment is used to cut off the lateral sprue material connected to the outer side of the sealing body formed on the outer periphery of the electronic detonator control module after sealing, the sprue cutting tool can be used to cut the sprue material formed at the lateral glue inlet channel, so that the sprue material connected to the two adjacent electronic detonators can be cut off. The sprue material between the detonator control modules is cut off by punching, which improves the efficiency of cutting off the lateral sprue material connected to the outer side of the sealant body formed on the periphery of the sealed electronic detonator control module, thereby improving the production efficiency of the electronic detonator control module. Furthermore, it is beneficial to arrange the multiple sprue cutting blades in a straight line at intervals in this embodiment, so as to simultaneously cut off the lateral sprue material connected to the outer side of the sealant body formed on the periphery of multiple sealed electronic detonator control modules arranged in a straight line, thereby improving the sprue material punching and cutting efficiency and improving the consistency of sprue material cutting.

[0009] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0010] According to one embodiment of this application, the punching protrusion is vertically connected to a first end in the length direction of the connecting body, and the punching protrusion extends horizontally out of the connecting body to a first side in the width direction of the connecting body. The second punching protrusion is vertically connected to the first end of the connecting body in the length direction, and the second punching protrusion extends horizontally out of the connecting body from the first punching protrusion in the width direction of the connecting body.

[0015] In this embodiment, the sprue punching knife includes a connecting seat.

[0017] In this embodiment, a connecting block is provided. The connecting block is connected to one end of the connecting seat and the connecting body along the height direction of the punching protrusion. A recessed clearance groove is formed between the other end of the connecting seat and the connecting body. When the sprue punching knife in this embodiment cuts off the lateral sprue connected to the outer side of the sealant body formed on the outer periphery of the sealed electronic detonator control module, it is beneficial to avoid the protruding parts directly opposite the recessed clearance groove through the recessed clearance groove. This helps to reduce interference between the sprue punching knife and other protruding parts during the sprue punching process.

[0018] According to another aspect of this application, a sprue blanking assembly for the production of electronic detonator control modules is provided, comprising: Connecting support base; The aforementioned sprue cutting tool for producing electronic detonator control modules includes multiple sprue cutting tools, which are spaced apart and connected to the connecting support base.

[0020] According to one embodiment of this application, the connecting support base has a long plate-like structure, and multiple sprue cutting blades are connected to the connecting support base in a straight line.

[0021] In this embodiment, multiple sprue cutting blades are arranged in a straight line and connected to the connecting support base. This facilitates the synchronous cutting of lateral sprue connected to the outer side of the sealant body formed by the outer periphery of the multiple electronic detonator control modules that have completed sealing, which are arranged in a straight line. This improves the efficiency of sprue cutting and also helps to improve the consistency of sprue cutting.

[0022] According to another aspect of this application, a sprue cutting device for the production of electronic detonator control modules is provided. This device is used to cut sprue from multiple encapsulated electronic detonator control modules. The encapsulated electronic detonator control modules are arrayed and connected to a circuit board. The circuit board has multiple slots spaced apart and arranged in an array. A substrate strip is formed between adjacent slots. Connecting wires and electronic components are respectively arranged on the circuit board strip to form the electronic detonator control module. Each of the multiple electronic detonator control modules is encapsulated to form an encapsulating body covering the outer periphery of the circuit board strip. Sprue formed by injection channels is connected to the outer periphery of each encapsulating body. The encapsulating body includes: The support limiting seat has a placement and storage limiting recessed groove on its upper side for placing the circuit board.

The above-mentioned sprue blanking assembly for the production of electronic detonator control modules has the connecting support seat mounted on the movable pressure seat, and multiple sprue blanking blades are arranged one by one facing multiple sprue blanks connected to the outer periphery of the sealing body. When the circuit board of multiple electronic detonator control modules connected with the encapsulated parts is placed in the placement and storage limiting recess, multiple encapsulated parts extend into the support recess, and the lower side of the encapsulated parts is abutted and supported by the upper side of the support recess; and when the movable pressure seat moves toward the support limiting seat to the punching position, the punching protrusion one and the punching protrusion two on the multiple sprue punching blades connected to the movable pressure seat can respectively cut off the sprue material connected to the outer periphery of the encapsulated parts; when the movable pressure seat moves away from the support limiting seat to the raised position, the multiple electronic detonator control modules that have completed the cutting of the sprue material placed in the placement and storage limiting recess can be taken out.

[0023] The sprue cutting device in this embodiment includes a support limiting seat, which facilitates placing the circuit board with multiple electronic detonator control modules connected to the encapsulated parts into the placement and storage limiting recess. Furthermore, the movable pressure seat has a punching position and a lifting position in the vertical direction relative to the support limiting seat, which facilitates moving the movable pressure seat toward the support limiting seat to the punching position, so that the sprue cutting blade can cut off the sprue connected to the outer periphery of the encapsulated body. In addition, it also facilitates moving the movable pressure seat away from the support limiting seat to the lifting position after the sprue is cut, so that the multiple electronic detonator control modules with the cut sprue placed in the placement and storage limiting recess can be removed.

[0024] According to one embodiment of this application, the projections of the first and second punching protrusions in the height direction fall within the width dimension of the sealant body. After the first and second punching protrusions respectively cut off the sprue material connected to the outer periphery of the sealant body and which is directly opposite to them, a recessed groove is formed at the position on the sealant body where the first and second punching protrusions are punched.

[0025] In this embodiment, the projections of punching protrusion 1 and punching protrusion 2 in the height direction fall within the width dimension of the sealant body. After punching protrusion 1 and punching protrusion 2 respectively cut off the sprue material connected to the outer periphery of the sealant body, the punched positions on the sealant body formed by punching protrusion 1 and punching protrusion 2 form recessed grooves. This helps to reduce the thickness of the sealant body that needs to be removed when cutting the sprue material, facilitates the removal of the sprue material, and helps to avoid the maximum width dimension of the sealant body formed by the sealing of the electronic detonator control module being too wide due to sprue material residue after removal.

[0026] According to one embodiment of this application, the sprue punching device for producing electronic detonator control modules further includes: A vertical movable guide assembly is connected to the support limiting seat or the movable pressure seat.

[0055] Furthermore, such as Figure 7 and Figure 9As shown, in this embodiment, the upper side of the support limiting seat 3 is provided with multiple placement positioning posts 33. The placement positioning posts 33 are located in the placement and storage limiting recess 31 and protrude vertically upward. The placement positioning posts 33 are used to position the circuit board 6 when it is placed. After aligning the multiple positioning holes 614 on the circuit board 6 with the multiple placement positioning posts 33 one by one, the circuit board 6 is placed and positioned in the placement and storage limiting recess 31, so as to accurately place the multiple electronic detonator control modules connected to the circuit board 6 in the support recess 32. The contour of the placement and storage limiting recess 31 matches the contour of the circuit board 6. Furthermore, in this embodiment, the upper side of the support limiting seat 3 is provided with positioning post clearance holes 53 corresponding to the multiple placement positioning posts 33. The upper end of the placement positioning post 33 can extend into the positioning post clearance hole 53.

[0056] Furthermore, such as Figure 4 and Figure 6 As shown, in this embodiment, the front end of the connecting support base 2 is provided with multiple bolt holes 20, and correspondingly, the connecting support plate 4 is provided with multiple bolt holes 40 corresponding to the multiple bolt holes 20. The connecting support base 2 is fixedly installed on the connecting support plate 4 by bolts. In addition, in this embodiment, other fixed connection methods can also be used to fix the connecting support base 2 on the connecting support plate 4.

[0057] Furthermore, such as Figure 9 As shown, the circuit board 6 in this embodiment includes a connecting edge, multiple positioning support edges 60, and circuit board strips 61. The multiple circuit board strips 61 are connected to the connecting edge at intervals. In this embodiment, the connecting edge is arranged horizontally, and the multiple circuit board strips 61 are connected vertically to the front side of the connecting edge at intervals along the extension direction of the connecting edge. Two positioning support edges 60 are connected to the left and right ends of the connecting edge, respectively. Furthermore, the rear end of the positioning support edge 60 is provided with a positioning hole 614. Furthermore, in this embodiment, the end of the circuit board strip 61 that is away from the connecting edge is the ignition element connection end, and an igniter 612 is installed on the ignition element connection end. It should be noted that the circuit board 6 in this embodiment includes two connecting edges, and the middle of the two connecting edges is connected by a pre-cutting line. The two positioning support edges 60 located in the middle are also connected by a pre-cutting line. In this embodiment, there are two sets of electronic detonator control modules. Each set of electronic detonator control modules includes ten electronic detonator control modules. In addition, the number of electronic detonator control modules in each set of electronic detonator control modules can also be adjusted as needed.

[0058] In this embodiment, as Figure 9As shown, multiple electronic detonator control modules connected to the circuit board 6 are sealed using an injection molding die to obtain a sealed connector. The main flow channel, branch flow channel, and side flow channel on the injection molding die form a sprue assembly 7. The sprue assembly 7 includes a main runner sprue 70, a main runner sprue 71, a branch runner sprue 72, and a side runner sprue 73. Among them, the main runner sprue 70 is formed by molding the longitudinal main flow channel. Material 71 is shaped by the transverse main channel, the sprue material 72 is shaped by the branch channel, and the side sprue material 73 is shaped by the lateral flow channel. Further, by cutting off the side sprue material 73, the sprue assembly 7 can be cut off. In this embodiment, the sprue cutting blade 1 is specifically used to cut off the side sprue material 73. In this embodiment, after cutting off the side sprue material 73 from the sealing body 613 of the sealed electronic detonator control module, the following is obtained: Figure 10 The multi-shot electronic detonator control module connector shown has an arc-shaped recessed groove 6131 formed at the location where the side gating nozzle material 73 is cut off; it should be noted that the "side gating nozzle material" in this embodiment is the same as the "side gating nozzle material 73".

[0059] In this embodiment, as follows Figure 9 After the multiple electronic detonator control modules connected to the circuit board 6, which have been sealed, are placed in the placement and storage limiting recess 31, the movable pressure seat is driven to move downwards and punch away the sprue material around the sealant body 613. Then, the movable pressure seat is raised to the raised position, and the multiple electronic detonator control modules with the sprue material removed are taken out. It should be noted that in this embodiment, the "punching position" is the position reached by the sprue material punching blade 1 after cutting away the sprue material.

[0060] In this embodiment, as Figure 9 As shown, the rear end of the electronic detonator control module in this embodiment is connected to a pair of connection pins 611. After the multiple electronic detonator control modules that have been sealed and connected to the circuit board 6 are placed in the placement and storage limiting recess 31, one end of the connection pins 611 is set to face backward.

[0061] In one embodiment of this application, the projections of punching protrusion 101 and punching protrusion 202 in the height direction fall within the width dimension of the sealant body 613. After punching protrusion 101 and punching protrusion 202 respectively cut off the sprue material connected to the outer periphery of the sealant body 613, a recessed groove is formed at the punching position of punching protrusion 101 and punching protrusion 202 on the sealant body 613.

[0062] In this embodiment, the projections of punching protrusion 101 and punching protrusion 202 in the height direction fall within the width dimension of the sealant body 613. After punching protrusion 101 and punching protrusion 202 respectively cut off the sprue material connected to the outer periphery of the sealant body 613, the punched positions on the sealant body 613 formed by punching protrusion 101 and punching protrusion 202 form recessed grooves. This helps to reduce the thickness of the sealant body that needs to be removed when cutting the sprue material, facilitates the removal of the sprue material, and helps to avoid the maximum width dimension of the sealant body 613 formed by sealing the electronic detonator control module being too wide due to sprue material residue after removal.

[0063] One embodiment of this application, such as Figures 4 to 8 As shown, the sprue punching device for the production of electronic detonator control modules also includes: A vertical movable guide component is connected to the support limit seat 3 or the movable pressure seat. The movable pressure seat can slide vertically relative to the support limit seat 3 in the vertical direction under the guiding and limiting action of the vertical movable guide component, having a punching position and a lifting position.

[0064] In this embodiment, as Figures 4 to 8 As shown, in this embodiment, the vertical movable guide component is provided, which helps to guide and limit the movement of the movable pressure seat in the vertical direction, thereby improving the stability of the movable pressure seat in the vertical direction. This, in turn, helps to improve the reliability and stability of the multiple sprue cutting blades 1 installed on the movable pressure seat for cutting sprue.

[0065] In this embodiment, as Figures 4 to 8 As shown, the vertical movable guide assembly in this embodiment includes guide support rods 41 and guide limiting rings 411. Multiple guide support rods 41 and multiple guide limiting rings 411 are provided, with multiple guide limiting rings 411 fixedly sleeved on the outer periphery of the guide support rods 41. In this embodiment, the guide support rods 41 are fixedly connected to the lower end of the connecting support plate 4 and extend vertically downwards. In this embodiment, the limiting plate 5 has guide limiting through holes 54 directly opposite the guide support rods 41. The guide support rods 41 extend downwards, and multiple guide limiting rings 411 are fixedly sleeved on the guide support rods 41, with the guide limiting rings 411 slidably inserted into the guide limiting through holes 54. Furthermore, in this embodiment, the support limiting seat 3 has guide through holes 34 respectively directly opposite the multiple guide support rods 41, with the guide limiting rings 411 slidably inserted into the guide through holes 34, enabling guidance of the vertical movement of the movable pressure seat.

[0066] Furthermore, the movable pressure seat in this embodiment can be connected to a vertical movable drive device, which drives the movable pressure seat to move in the vertical direction. Furthermore, the movable pressure seat can also be raised and lowered by production operators, giving it a punching position and a raised position. Additionally, the vertical movable guide component in this embodiment can have other structures, and there are various ways to achieve the punching and raised positions of the movable pressure seat in the vertical direction, which will not be elaborated here.

[0067] One embodiment of this application, such as Figure 3 and Figure 5 As shown, the connecting support 2 is provided with movable limiting protrusions 21. Multiple movable limiting protrusions 21 are provided facing multiple circuit board strips 61. Multiple movable limiting protrusions 21 are used to stop against the circuit board strips 61.

[0068] In this embodiment, as Figure 3 and Figure 5 As shown, in this embodiment, the connecting support 2 is provided with multiple movable limiting protrusions 21 facing multiple circuit board strips 61. When using the sprue cutting device in this embodiment to cut the lateral sprue material connected to the outer side of the sealant body 613 formed on the outer periphery of the sealed electronic detonator control module, it is beneficial to constrain the movement of the circuit board strips 61 by the multiple movable limiting protrusions 21, so as to prevent the circuit board strips 61 from moving too much during the punching process of the sprue material and affecting the accuracy of cutting the sprue material. In this embodiment, the movable limiting protrusions 21 are specifically used to prevent the front end of the circuit board strips 61 from tilting upward.
