Description

Technical Field

[0001] This utility model relates to the field of automated testing technology for injection molding equipment, specifically to a smoke shielding mechanism for an image acquisition system used in injection molding equipment. Background Technology

[0002] In injection molding, the collaborative application of image acquisition systems and injection molding equipment has become a key technical means to improve the efficiency of product quality control. This system typically consists of a light source and a camera, and its core functions include: pre-injection imaging to confirm the presence and position of inserts placed in the mold, and post-injection automated inspection of the finished product's appearance to verify product dimensions, shape, and surface defects, and to confirm whether the insert condition meets design requirements.

[0003] At the moment the injection molding machine completes injection and opens the mold, the high-temperature molten plastic releases a large amount of volatile gases and particles during the cooling and solidification process within the mold cavity, forming a mixed fumes. These fumes not only directly contaminate the optical components (light source, camera lens) of the image acquisition system, but also rapidly diffuse within the confined space of the injection molding workshop, significantly interfering with image quality. In existing technologies, to mitigate the impact of fumes on image acquisition, the main approach is to use an exhaust system to remove the fumes from the working area via negative pressure suction.

[0004] However, the ventilation system can only reduce the concentration of smoke suspended in the air, and cannot completely prevent the deposition of smoke particles on the surface of optical components. Oily deposits or particulate contaminants will still form on the surface of the light source and camera lens. This will not only reduce the light transmittance of the light source and decrease the brightness of the illumination, thus causing insufficient camera exposure or increased image noise, but also cause blurred edges and loss of details in the detection image. In severe cases, it can lead to the automated detection system misjudging the product pass rate and increase the risk of defective products leaving the system.

[0005] Therefore, how to provide a smoke shielding mechanism for an image acquisition system for injection molding equipment, and solve the defects in the existing technology, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] To address this issue, this invention provides a smoke shielding mechanism for an image acquisition system used in injection molding equipment.

Several air outlets are opened on the surface of the positive pressure air pipe.

[0017] A cylinder bracket is installed at the bottom of the light source cover, and a folding plate is rotatably connected inside the cylinder bracket;

[0018] The light source cover opening and closing cylinder is rotatably connected to the inside of the cylinder bracket, and the output end of the light source cover opening and closing cylinder is movably connected to the folding plate;

[0019] The light source cover opening and closing door is installed on the side wall of the folding plate near the light source cover, and the light source cover opening and closing door can open / close the opening of the light source cover.

[0020] Furthermore, the light source support includes:

[0021] A fixing block is installed on the profile frame behind the injection molding equipment, and an installation groove is provided on the outer side wall of the fixing block;

[0022] The support arm is disposed within the mounting slot;

[0023] The fixing plate is connected to the fixing block by bolts and the bracket arm is fixed in the mounting groove.

[0024] Furthermore, the camera smoke shielding assembly includes:

[0025] The camera bracket is mounted on the profile frame behind the injection molding equipment;

[0026] An L-shaped mounting plate is installed on the top wall of the camera bracket;

[0027] The camera cover is a hollow structure with an opening on one side. The camera cover is installed on the side wall of the L-shaped mounting plate, and the camera body is installed on the inner wall of the camera cover.

[0028] The camera cover opening and closing door is slidably connected to the opening of the camera cover;

[0029] A cylinder connecting plate is mounted on the side wall of the camera cover;

[0030] A camera cover opening and closing cylinder is installed on the side wall of the cylinder connecting plate. The output end of the camera cover opening and closing cylinder passes through the cylinder connecting plate and is connected to a lever.

[0035] This utility model has the following advantages:

[0036] This invention utilizes a light source smoke shielding component to keep the light source in a closed protective space when not in use. Combined with a light source cover opening and closing cylinder and a light source cover opening and closing door, it achieves dynamic protection by "lighting on during shooting and sealing off when not shooting." Furthermore, a positive pressure air pipe introduces positive pressure airflow into the light source cover, effectively preventing external smoke from seeping into the cover and blocking the contact path between smoke and the light source. This allows the light source to operate at its optimal state for extended periods, providing sufficient illumination for the camera. By incorporating a camera smoke shielding component, an independent protective space is created around the camera body. Combined with a camera cover opening and closing door and a camera cover opening and closing cylinder, it achieves dynamic protection by "exposure during shooting and sealing off when not shooting." The positive pressure blower nozzle further effectively blocks external smoke penetration, ensuring the camera lens remains clear for an extended period. This reduces the frequency of manual cleaning and avoids problems such as blurred edges, loss of detail, and reduced product yield caused by smoke adhering to the lens. By setting a scale on the light source bracket and cooperating with the fixing plate, the extension length of the bracket arm can be accurately recorded, facilitating the adjustment of the light source body's position. The angle of the light source cover can be recorded by setting an angle adjustment dial on the light source bracket. Similarly, by setting a scale and pointer on the camera bracket, the position of the camera cover can be accurately recorded; and the shooting angle of the camera cover can be recorded by setting an angle adjustment dial on the camera bracket.

[0047] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] Please refer to Figures 1-7 The present invention discloses a smoke shielding mechanism for an image acquisition system used in injection molding equipment. The present invention consists of four parts, as follows: Figure 1As shown, the system includes a light source smoke shielding assembly 1, a light source body 2, a camera smoke shielding assembly 3, and a camera body 4. The light source smoke shielding assembly 1 is mounted on a profile frame behind the injection molding equipment. The light source body 2 is installed inside the light source smoke shielding assembly 1. The camera smoke shielding assembly 3 is mounted on the profile frame behind the injection molding equipment and is located below the light source smoke shielding assembly 1. The camera body 4 is installed inside the camera smoke shielding assembly 3. In this embodiment, the injection molding equipment needs to remain stable and avoid shaking during injection molding operations. Therefore, a profile frame is generally provided at the rear of the injection molding equipment. The profile frame can firmly fix the injection molding equipment in the injection molding workshop. The light source smoke shielding assembly 1 and the camera smoke shielding assembly 3 are fixed on the profile frame behind the injection molding equipment. This mechanism also needs to cooperate with the exhaust system in the prior art during operation.

[0049] By setting up the light source smoke shielding component 1, the light source body 2 can be kept in a closed protective space when not under illumination. Combined with the light source cover opening and closing cylinder 18 and the light source cover opening and closing door 19, dynamic protection is achieved by "lighting on during shooting and sealing off when not shooting." Furthermore, the positive pressure air pipe 13 introduces positive pressure airflow into the light source cover 12, effectively preventing external smoke from seeping into the interior of the light source cover 12 and blocking the contact path between smoke and the light source body 2. This allows the light source body 2 to remain in optimal working condition for extended periods, providing sufficient illumination for the camera body 4. By setting up the camera smoke shielding component 3, an independent protective space is constructed around the camera body 4. Combined with the camera cover opening and closing door 34 and the camera cover opening and closing cylinder 36, dynamic protection is achieved by "exposure during shooting and sealing off when not shooting." Combined with the positive pressure blowing nozzle 38, external smoke penetration is effectively blocked, ensuring the camera lens remains clear for a long time. This fundamentally avoids the problem of blurred edges, loss of detail, and reduced product qualification rate caused by smoke adhering to the lens.

[0050] like Figure 2 , Figure 4As shown, the light source smoke shielding assembly 1 includes a light source bracket 11, a light source cover 12, a light source positive pressure air pipe 13, a cylinder bracket 16, a light source cover opening and closing cylinder 18, and a light source cover opening and closing door 19. The light source brackets 11 are arranged in pairs and are respectively installed on the profile frame behind the injection molding equipment. The light source cover 12 is a hollow structure with an opening on one side. The light source cover 12 is installed between the two light source brackets 11. The light source body 2 is installed on the inner wall of the light source cover 12. The light source positive pressure air pipe 13 is located inside the light source cover 12, and light sources extend from both ends of the light source positive pressure air pipe 13. The source cover 12 is connected to an air inlet 14. The surface of the positive pressure air pipe 13 of the light source is provided with several air outlets 15. The cylinder bracket 16 is installed at the bottom of the source cover 12. The inside of the cylinder bracket 16 is rotatably connected to a folding plate 17. The source cover opening and closing cylinder 18 is rotatably connected to the inside of the cylinder bracket 16. The output end of the source cover opening and closing cylinder 18 is movably connected to the folding plate 17. The source cover opening and closing door 19 is installed on the side wall of the folding plate 17 near the source cover 12. The source cover opening and closing door 19 can open / close the opening of the source cover 12.

[0051] In this embodiment, a gasket is provided between the light source bracket 11 and the light source cover 12. The light source bracket 11 and the gasket are connected to the side wall of the light source cover 12 by bolts. The two ends of the light source positive pressure air pipe 13 are connected to an external positive pressure air supply system through air inlets 14. Positive pressure gas is blown out from several air outlets 15 on the surface of the light source positive pressure air pipe 13. The cylinder bracket 16 is shaped as follows: Figure 2 As shown, the middle part of the folding plate 17 is rotatably connected to the cylinder bracket 16, so that both ends of the folding plate 17 are on the sides of the cylinder bracket 16 with the cylinder bracket 16 as the axis. The upper part of the folding plate 17 is equipped with the light source cover opening and closing door 19, and the lower part of the folding plate 17 is rotatably connected to the output end of the light source cover opening and closing cylinder 18. It is worth noting that the light source cover opening and closing cylinder 18 is in a rotatable state on the cylinder bracket 16. This is to cooperate with the rotation of the folding plate 17. In addition, a limit beam is provided at the top of the cylinder bracket 16. The function of the limit beam is to prevent the light source cover opening and closing cylinder 18 from over-twisting when opening / closing the light source cover opening and closing door 19.

[0052] During use, when the injection molding machine is about to open the mold, positive pressure gas is introduced into the positive pressure air pipe 13 of the light source through the air inlet 14, so that the inside of the light source cover 12 is in a positive pressure state, preventing a large amount of smoke during mold opening from seeping into the inside of the light source cover 12 and contacting the light source body 2. After the external exhaust system exhausts the smoke, the light source cover opening and closing cylinder 18 is activated and retracted, driving the folding plate 17 to rotate on the cylinder bracket 16, thereby opening the light source cover opening and closing door 19, at which time the light source body 2 can illuminate the product; when the light source cover opening and closing cylinder 18 extends, the folding plate 17 rotates upward, and the light source cover opening and closing door 19 closes the opening of the light source cover 12.

[0053] like Figure 3As shown, the light source bracket 11 includes a fixing block 111, a bracket arm 113, and a fixing plate 114. The fixing block 111 is installed on the profile frame behind the injection molding equipment. A mounting groove 112 is formed on the outer wall of the fixing block 111. The bracket arm 113 is disposed within the mounting groove 112. The fixing plate 114 is connected to the fixing block 111 by bolts, thus fixing the bracket arm 113 within the mounting groove 112. In this embodiment, the specific shape of the light source bracket 11 is as follows: Figure 3 As shown, the function of the mounting groove 112 is to restrict the direction of the support arm 113. The support arm 113 can only extend and retract along the direction of the mounting groove 112. The surface of the fixing plate 114 has two through holes, and the surface of the fixing block 111 has a hole that matches it. The bolt passes through the fixing plate 114 and the support arm 113 in sequence and is threadedly connected to the fixing block 111.

[0054] like Figure 5 , Figure 6 As shown, the camera smoke shielding assembly 3 includes a camera bracket 31, an L-shaped mounting plate 32, a camera cover 33, a camera cover opening / closing door 34, a cylinder connecting plate 35, a camera cover opening / closing cylinder 36, a positive pressure blowing nozzle 38, and a temperature sensor 39. The camera bracket 31 is mounted on the profile frame behind the injection molding equipment. The L-shaped mounting plate 32 is mounted on the top wall of the camera bracket 31. The camera cover 33 is a hollow structure with an opening on one side and is mounted on the side wall of the L-shaped mounting plate 32. The camera body 4 is mounted on the inner wall of the camera cover 33. The camera cover opening and closing door 34 is slidably connected to the opening of the camera cover 33. The cylinder connecting plate 35 is installed on the side wall of the camera cover 33. The camera cover opening and closing cylinder 36 is installed on the side wall of the cylinder connecting plate 35. The output end of the camera cover opening and closing cylinder 36 passes through the cylinder connecting plate 35 and is connected to a lever 37. The lever 37 is connected to the camera cover opening and closing door 34. The positive pressure blowing nozzle 38 is installed on the inner wall of the camera cover 33. The temperature sensor 39 is installed on the rear side wall of the camera cover 33. The temperature sensor 39 is used to detect the temperature inside the camera cover 33.

[0055] In this embodiment, the camera bracket 31 is a profile column, perpendicular to the profile frame behind the injection molding equipment. A gasket is provided between the L-shaped mounting plate 32 and the camera cover 33. The camera cover 33 and the gasket are installed on the side wall of the camera bracket 31 by bolts. An angle iron is installed on the profile frame behind the injection molding equipment and is located on the lower side of the camera bracket 31, supporting the camera bracket 31. The camera cover opening / closing cylinder 36 is located on the lower side of the camera cover 33 via a cylinder connecting plate 35. A lever 37 is connected to one end of the camera cover opening / closing door 34. When the camera cover opening / closing cylinder 36 retracts, the lever 37 pushes the camera cover opening / closing door 34 to close the opening of the camera cover 33. Figure 6As shown, the air inlet 14 of the positive pressure blower nozzle 38 extends through to the rear wall of the camera housing 33 and connects to the external positive pressure air supply system. The temperature sensor 39 is positioned as follows... Figure 6 As shown, the temperature sensor 39 monitors the temperature parameters inside the camera housing 33 in real time. When an abnormal temperature is detected (such as when smoke accumulates and heat radiation increases), an alarm can be triggered to protect the camera body 4. There is also a circular opening on the rear side wall of the camera for connecting the wiring harness at the back of the camera body 4. It is worth noting that since the camera housing 33 is at a downward tilt angle and the smoke rises, this circular opening will not allow smoke to enter the camera housing 33.

[0056] During use, when the injection molding machine is about to open the mold, positive pressure gas is introduced into the camera cover 33 through the positive pressure blower nozzle 38, so that the camera cover 33 is in a positive pressure state, preventing a large amount of smoke during mold opening from seeping into the camera cover 33 and contacting the camera body 4. After the external exhaust system exhausts the smoke, the camera cover opening and closing cylinder 36 extends, and the lever 37 will drive the camera cover opening and closing door 34 to open the opening of the camera cover 33, at which time the camera body 4 can take pictures of the product.

[0057] like Figure 3 As shown, a groove 1131 is provided on the side wall of the support arm 113, and a scale 1132 for the light source support is installed in the groove 1131. An angle adjustment dial 1133 for the light source support is installed at the end of the support arm 113 that connects to the light source cover 12. In this embodiment, the positions of the scale 1132 and the angle adjustment dial 1133 for the light source support are as follows: Figure 3 As shown, by setting the scale 1132 of the light source bracket, it can cooperate with the fixing plate 114 to accurately record the extension length of the bracket arm 113, which provides convenience for adjusting the position of the light source body 2; by setting the angle adjustment dial 1133 of the light source bracket, the angle of the light source cover 12 can be recorded.

[0058] like Figure 7 As shown, a camera bracket scale 311 is mounted on the side wall of the camera bracket 31, a pointer 312 that mates with the camera bracket scale 311 is mounted on the side wall of the L-shaped mounting plate 32, and a camera bracket angle adjustment dial 313 is mounted on the side wall of the L-shaped mounting plate 32. In this embodiment, the positions of the camera bracket scale 311, pointer 312, and camera bracket angle adjustment dial 313 are as follows: Figure 7 As shown, by setting the camera bracket scale 311 and pointer 312, the position of the camera cover 33 can be accurately recorded; by setting the camera bracket angle adjustment dial 313, the shooting angle of the camera cover 33 can be recorded.

[0059] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
