Description

Technical Field

[0001] This invention relates to the field of industrial electronic detonator manufacturing technology, specifically to an industrial electronic detonator assembly equipment and production testing method. Background Technology

[0002] Industrial electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. Industrial electronic detonators have very high safety and stability requirements, necessitating testing to ensure their conformity before leaving the factory.

[0003] Industrial electronic detonators require piercing the wires and their internal connecting terminals during use to electrically connect the control chip inside the detonator with the external detonating agent, thereby achieving precise control of the detonation point. Therefore, the assembly reliability of the connecting terminals in industrial electronic detonators is particularly important. Currently, the main assembly process for the connecting terminals in industrial electronic detonators involves the operator using their hand or a clamp to insert the connecting terminals into the positioning grooves on the bottom cover. Because the connecting terminals require piercing the wires, a sharp piercing point is formed on the outward side of the connecting terminal, making it extremely easy for operators to cut their fingers when assembling by hand. If a clamp is used for clamping, the connecting terminals are easily deformed by compression, affecting the quality of the electrical connection during subsequent use.

[0004] Therefore, there is an urgent need to develop a reliable assembly scheme for the connection terminals of industrial electronic detonators to ensure the quality of electrical connections. Summary of the Invention

[0005] To solve the above problems, the technical solution provided by the present invention is as follows:

[0006] An industrial electronic detonator assembly device includes an assembly table, a bottom cover feeding mechanism located at one end of the assembly table, a terminal clamping mechanism located on one side of the assembly table, a terminal pressing mechanism located on one side of the assembly table, a pushing mechanism located on one side of the assembly table, and a detection mechanism located at the other end of the assembly table. The assembly table is provided with an assembly track. The bottom cover feeding mechanism feeds the bottom cover into the assembly track. The pushing mechanism moves the bottom cover on the assembly track. The terminal clamping mechanism clamps the connecting terminal onto the bottom cover. The terminal pressing mechanism presses the connecting terminal into the slot of the bottom cover. The detection mechanism detects the bottom cover after pressing.

[0007] A production and testing method for industrial electronic detonators, employing the aforementioned industrial electronic detonator assembly equipment, comprising:

[0008] The bottom cover feeding vibratory feeder sends the bottom cover into the bottom cover feeding platform. The bottom cover horizontal power source and the bottom cover vertical power source drive the bottom cover pusher plate to move, pushing the bottom cover into the bottom cover receiving groove of the separator substrate. The main pusher power source drives the main sliding plate to move, and the auxiliary pusher power source drives the auxiliary sliding plate to move, driving the separator substrate to push the bottom cover to the position on the assembly table near the terminal clamping mechanism.

[0009] The terminal feeding vibratory feeder feeds the connecting terminals into the terminal feeding station. The horizontal and vertical power sources of the terminals drive the clamping power source to move above the terminal feeding station. The clamping power source drives the grippers to clamp the connecting terminals. The horizontal and vertical power sources of the terminals drive the clamping power source to move above the assembly table and insert the connecting terminals into the bottom cover. The clamping power source drives the grippers to release the connecting terminals. The main pushing power source drives the main sliding plate to move, and the auxiliary pushing power source drives the auxiliary sliding plate to move, which drives the material separating plate to push the material and move the bottom cover with the clamped connecting terminals to the position on the assembly table near the terminal pressing mechanism.

[0010] The pressing power source drives the pressing stroke seat to move to one side of the assembly table. The pressing part touches the connecting terminal inside the bottom cover and presses the connecting terminal into the slot of the bottom cover. The spring reset part is compressed. After the pressing is completed, the pressing power source drives the pressing stroke seat to move away from the assembly table.

[0011] After the bottom cover with the connecting terminals crimped, it enters the inspection conveyor and is adjusted to a preset posture by the posture adjustment plate. The first inspection camera detects whether there are connecting terminals inside the bottom cover in the preset posture, and the second inspection camera detects whether the connecting terminals inside the bottom cover in the preset posture meet the preset requirements. If the bottom cover fails to pass the product image inspection of either the first or second inspection camera in the preset posture, the rejection component rejects the bottom cover. If the bottom cover passes the product image inspection of both the first and second inspection cameras in the preset posture, the bottom cover is determined to be qualified and is unloaded normally.

[0012] The present invention further comprises the following steps in the product image detection step:

[0013] In response to the image detection signal, the first detection camera and the second detection camera respectively acquire the first product image information and the second product image information under a preset posture;

[0014] The first product image information is input into the first detection training model, and feature points are extracted from the first product image information; anchor boxes are formed for the first product image based on the feature points, and the maximum anchor box image formed by the feature points is determined; the maximum anchor box image is binarized to obtain a binarized image, and the pixels in the binarized image are denoised to obtain a denoised binarized image; the target contour is extracted from the foreground color pixels in the denoised binarized image, and the overlap degree between the target contour and the preset connection terminal image is judged to output the first detection result;

[0015] The second product image information is input into the second detection training model to extract feature points from the first product image information. Anchor frames are constructed for the first product image based on the feature points to determine the maximum anchor frame image formed by the feature points. The maximum anchor frame image is binarized and a Cartesian coordinate system is constructed on the maximum anchor frame image. Feature points within the maximum anchor frame image are divided according to the gray values ​​of adjacent pixels. The divided feature points are connected to obtain feature line segments. The shortest distance between multiple feature line segments is calculated. Based on the relationship between a preset distance threshold and the shortest distance between feature line segments, it is determined whether abnormal deformation has occurred at the critical puncture site of the connecting terminal, so as to output the second detection result.

[0016] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0017] This technical solution for industrial electronic detonator assembly equipment can stably connect sharp connecting terminals into the base cover, realizing the assembly of industrial electronic detonator base components. The entire assembly process is automated, with high overall assembly efficiency and good consistency, and it also avoids injury to workers from the sharp ends of the connecting terminals. Moreover, after the assembly is completed, the industrial electronic detonator base components are visually inspected to ensure that the components are qualified to enter the next process, thus guaranteeing the quality of use of industrial electronic detonators.

[0052] Example 2

[0053] Combined with appendix Figure 2 The present invention provides a production and testing method for industrial electronic detonators, employing the industrial electronic detonator assembly equipment described in Example 1, comprising:

[0054] The bottom cover feeding vibratory feeder sends the bottom cover into the bottom cover feeding platform. The bottom cover horizontal power source and the bottom cover vertical power source drive the bottom cover pusher plate to move, pushing the bottom cover into the bottom cover receiving groove of the separator substrate. The main pusher power source drives the main sliding plate to move, and the auxiliary pusher power source drives the auxiliary sliding plate to move, driving the separator substrate to push the bottom cover to the position on the assembly table near the terminal clamping mechanism.

[0055] The terminal feeding vibratory feeder feeds the connecting terminals into the terminal feeding station. The horizontal and vertical power sources of the terminals drive the clamping power source to move above the terminal feeding station. The clamping power source drives the grippers to clamp the connecting terminals. The horizontal and vertical power sources of the terminals drive the clamping power source to move above the assembly table and insert the connecting terminals into the bottom cover. The clamping power source drives the grippers to release the connecting terminals. The main pushing power source drives the main sliding plate to move, and the auxiliary pushing power source drives the auxiliary sliding plate to move, which drives the material separating plate to push the material and move the bottom cover with the clamped connecting terminals to the position on the assembly table near the terminal pressing mechanism.

[0056] The pressing power source drives the pressing stroke seat to move to one side of the assembly table. The pressing part touches the connecting terminal inside the bottom cover and presses the connecting terminal into the slot of the bottom cover. The spring reset part is compressed. After the pressing is completed, the pressing power source drives the pressing stroke seat to move away from the assembly table.

[0057] After the bottom cover with the connecting terminals crimped, it enters the inspection conveyor and is adjusted to a preset posture by the posture adjustment plate. The first inspection camera detects whether there are connecting terminals inside the bottom cover in the preset posture, and the second inspection camera detects whether the connecting terminals inside the bottom cover in the preset posture meet the preset requirements. If the bottom cover fails to pass the product image inspection of either the first or second inspection camera in the preset posture, the rejection component rejects the bottom cover. If the bottom cover passes the product image inspection of both the first and second inspection cameras in the preset posture, the bottom cover is determined to be qualified and is unloaded normally.

[0058] The above embodiments describe the workflow of automated assembly of industrial electronic detonator base components and image detection of the components; for image detection, there are also target component connection relationships and target component size detection, and the specific detection scheme is as follows.

[0059] In this embodiment, the product image detection step includes:

[0060] In response to the image detection signal, the first detection camera and the second detection camera respectively acquire the first product image information and the second product image information under a preset posture;

[0061] The first product image information is input into the first detection training model, and feature points are extracted from the first product image information; anchor boxes are formed for the first product image based on the feature points, and the maximum anchor box image formed by the feature points is determined; the maximum anchor box image is binarized to obtain a binarized image, and the pixels in the binarized image are denoised to obtain a denoised binarized image; the target contour is extracted from the foreground color pixels in the denoised binarized image, and the overlap degree between the target contour and the preset connection terminal image is judged to output the first detection result;

[0062] The second product image information is input into the second detection training model to extract feature points from the first product image information. Anchor frames are constructed for the first product image based on the feature points to determine the maximum anchor frame image formed by the feature points. The maximum anchor frame image is binarized and a Cartesian coordinate system is constructed on the maximum anchor frame image. Feature points within the maximum anchor frame image are divided according to the gray values ​​of adjacent pixels. The divided feature points are connected to obtain feature line segments. The shortest distance between multiple feature line segments is calculated. Based on the relationship between a preset distance threshold and the shortest distance between feature line segments, it is determined whether abnormal deformation has occurred at the critical puncture site of the connecting terminal, so as to output the second detection result.

[0063] In the above embodiments, the image detection signal can be a position signal triggered by a counting sensor or triggered by another position sensor.

[0064] In the above embodiments, both the first detection training model and the second detection training model include the extraction of feature points of product image information. The feature points are obtained by performing feature point anchoring training on several images under a preset posture. It should be noted that the several images under the preset posture cover the images of the target product taken by the first detection camera and the second detection camera from different angles. The anchored feature points are the corner points of the bottom cover and the corner points of the connecting terminals.

[0065] In the above embodiments, the feature points of the maximum anchor frame image are determined to be the feature points corresponding to the corner points of the bottom cover; the feature points within the maximum anchor frame image are the feature points corresponding to the corner points of the connecting terminals.

[0066] In the above embodiments, binarization of the maximum anchor frame image is performed by calculating the average pixel value of all pixels in the maximum anchor frame image, and then dividing the foreground and background according to the magnitude of the average pixel value and the original pixel value to obtain a binarized image.

[0067] In the above embodiment, after obtaining the binarized image, the corner points of the connecting terminal can be divided into two sides according to the difference in gray values ​​of adjacent pixels at the feature points. The line segment obtained by connecting the divided corner points is the key boundary of the puncture site of the connecting terminal.

[0068] In the above embodiment, the feature line segment in the process of the second detection training model processing the second product image information is the boundary line of the key puncture part of the connecting terminal under the preset posture. The shortest distance of the boundary line determines whether the connecting terminal has undergone unacceptable deformation.

[0069] In the above embodiment, the first inspection camera inspects the assembled industrial electronic detonator bottom cover assembly to check whether the connecting terminals are properly installed on the bottom cover. Specific inspection images are attached. Figure 14 As shown; the second inspection camera inspects the connecting terminals on the assembled industrial electronic detonator bottom cover assembly, checking whether the key puncture points of the connecting terminals are qualified. Specific inspection images are attached. Figure 15 As shown.

The output terminal of the controller is connected to the input terminal of the bottom cover horizontal power source and the input terminal of the bottom cover vertical power source, respectively. The methods include: The bottom cover feeding vibratory feeder sends the bottom cover into the bottom cover feeding platform. The bottom cover horizontal power source and the bottom cover vertical power source drive the bottom cover pusher plate to move, pushing the bottom cover into the bottom cover receiving groove of the separator substrate. The main pusher power source drives the main sliding plate to move, and the auxiliary pusher power source drives the auxiliary sliding plate to move, driving the separator substrate to push the bottom cover to the position on the assembly table near the terminal clamping mechanism. The terminal feeding vibratory feeder feeds the connecting terminals into the terminal feeding station. The horizontal and vertical power sources of the terminals drive the clamping power source to move above the terminal feeding station. The clamping power source drives the grippers to clamp the connecting terminals. The horizontal and vertical power sources of the terminals drive the clamping power source to move above the assembly table and insert the connecting terminals into the bottom cover. The clamping power source drives the grippers to release the connecting terminals. The main pushing power source drives the main sliding plate to move, and the auxiliary pushing power source drives the auxiliary sliding plate to move, which drives the material separating plate to push the material and move the bottom cover with the clamped connecting terminals to the position on the assembly table near the terminal pressing mechanism. The pressing power source drives the pressing stroke seat to move to one side of the assembly table. The pressing part touches the connecting terminal inside the bottom cover and presses the connecting terminal into the slot of the bottom cover. The spring reset part is compressed. After the pressing is completed, the pressing power source drives the pressing stroke seat to move away from the assembly table. After the bottom cover with the connecting terminals crimped, it enters the inspection conveyor and is adjusted to a preset posture by the posture adjustment plate. The first inspection camera detects whether there are connecting terminals inside the bottom cover in the preset posture, and the second inspection camera detects whether the connecting terminals inside the bottom cover in the preset posture meet the preset requirements. If the bottom cover fails to pass the product image inspection of either the first or second inspection camera in the preset posture, the rejection component rejects the bottom cover. If the bottom cover passes the product image inspection of both the first and second inspection cameras in the preset posture, the bottom cover is determined to be qualified and is unloaded normally.

2. The production and testing method for an industrial electronic detonator according to claim 1, characterized in that, The product image detection step includes: In response to the image detection signal, the first detection camera and the second detection camera respectively acquire the first product image information and the second product image information under a preset posture; The first product image information is input into the first detection training model, and feature points are extracted from the first product image information; anchor boxes are formed for the first product image based on the feature points, and the maximum anchor box image formed by the feature points is determined; the maximum anchor box image is binarized to obtain a binarized image, and the pixels in the binarized image are denoised to obtain a denoised binarized image; the target contour is extracted from the foreground color pixels in the denoised binarized image, and the overlap degree between the target contour and the preset connection terminal image is judged to output the first detection result; The second product image information is input into the second detection training model to extract feature points from the first product image information. Anchor frames are constructed for the first product image based on the feature points to determine the maximum anchor frame image formed by the feature points. The maximum anchor frame image is binarized and a Cartesian coordinate system is constructed on the maximum anchor frame image. Feature points within the maximum anchor frame image are divided according to the gray values ​​of adjacent pixels. The divided feature points are connected to obtain feature line segments. The shortest distance between multiple feature line segments is calculated. Based on the relationship between a preset distance threshold and the shortest distance between feature line segments, it is determined whether abnormal deformation has occurred at the critical puncture site of the connecting terminal, so as to output the second detection result.
