Description

Technical Field

[0001] This utility model relates to the field of protection technology for photodetectors, specifically a protection device for photodetectors with anti-collision and shielding functions. Background Technology

[0002] In the production process of freeze-dried drugs, the freeze-drying process is an important step. The freeze-drying machine's production is divided into two processes: one is filling into the box before freeze-drying, and the other is sealing and unpacking after freeze-drying. During the box filling process, the photoelectric sensor in front of the bottle feed wheel is mainly responsible for detecting and informing the freeze-drying machine.

[0003] In the existing technology, the use of detection photocells faces two disadvantages. First, the sensitivity of the photocell is affected by the different detection distances of different modules and interference from external lighting, often resulting in false alarms and requiring recalibration. Second, the photocell is directly mounted on the photocell bracket and is close to the track rail. During the production process, the track rail must be replaced when the photocell is loaded into and unloaded. Since the rail has a certain weight, it is often bumped or squeezed during replacement, causing changes in the photocell's position and accuracy, or even damage. Therefore, the existence of these two situations not only affects the continuity and stability of equipment operation, but also increases the frequency and cost of spare parts replacement, without providing adequate protection for the detection photocell. Summary of the Invention

[0004] The purpose of this invention is to provide a protective device for a detection photoelectric sensor with anti-collision and shielding functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A protective device for a detection photoelectric sensor with anti-collision and shielding functions includes a protective cover. A transparent window is provided in the middle of the front face of the protective cover. Lights are provided at the four corners of the transparent window on the front face of the protective cover. Several airbag columns are provided on the outer wall of the protective cover except for the transparent window. Several ventilation holes are opened in the gaps between the airbag columns on the left end face of the protective cover. A circular groove is opened on the right end face of the protective cover. A heat dissipation device for accelerating internal ventilation is provided in the circular groove. A mounting bracket is provided below the protective cover. A fixing seat is provided on the top of the mounting bracket. A detection photoelectric sensor is provided on the front face of the fixing seat.

[0007] The heat dissipation device includes a heat dissipation cylinder and a fan installed inside the heat dissipation cylinder, and a protective net is provided at the right end of the heat dissipation cylinder.

[0008] Furthermore, the bottom of the fixed base and the top of the mounting bracket are integrally formed, and the detection photoelectric sensor is fixedly connected to the fixed base by screws.

[0009] In this invention, the mounting base is installed near the track rail. The photoelectric sensor passes through the mounting bracket via a guide and is electrically connected to the processor of the corresponding freeze dryer. The image information captured by the photoelectric sensor is transmitted to the processor of the freeze dryer for corresponding data processing.

[0010] Specifically, a screw hole is provided at the center of the front end face of the fixed base, and a through hole is provided on the front end face of the protective cover corresponding to the screw hole, with a fastening bolt provided in the through hole.

[0011] In this invention, the fastening bolt passes through the through hole and is threadedly connected to the screw hole, thereby achieving a stable combination and installation of the protective cover and the fixing base.

[0012] Furthermore, the width of the inner wall of the protective cover is adapted to the width of the outer wall of the fixing base, the protective cover and the fixing base are plugged into each other, and a handle is provided at the center of the upper surface of the protective cover, and both ends of the handle are welded and fixed to the top of the protective cover.

[0013] In this invention, the handle provides a point of leverage, making it easy to remove and replace the protective cover from above. The protective cover and the fixing base are tightly connected, increasing the stability of the installation and reducing gaps between the protective cover and the fixing base. Shaking will affect the tight fit and fixation.

[0014] It should be noted that the airbag column is hollow inside and filled with air. The airbag columns are evenly distributed and are bonded and fixed to the protective cover.

[0015] In this invention, the cooperation of multiple airbag columns reduces the damage caused by collisions between external objects and the outer surface of the protective cover. The airbag columns are filled with air to reduce the impact of collisions on the protective cover.

[0016] Furthermore, the transparent window is bonded and fixed to the side wall of the protective cover around its perimeter, and the lighting lamp is fixedly connected to the protective cover by screws.

[0017] In this invention, the transparent window is made of tempered glass, allowing the photoelectric sensor to easily detect reagent bottles passing on the conveyor track. When the track is full of reagent bottles, the photoelectric sensor sends a signal to the PLC to stop the machine and wait, activating the protective discharge push rod and the feeding push rod to prevent the discharge push rod and the feeding push rod from being deformed due to excessive reagent bottles in the track, which would prevent production from being halted. The lighting is connected to the control switch on the freeze dryer via a wire, turning on the lighting to enable detection of reagent bottles passing on the conveyor track in a dim environment.

[0018] It is worth noting that the ventilation holes are arranged in a matrix, and the inner port of the ventilation hole is higher than the outer port. The inner diameter of the circular groove is adapted to the outer diameter of the heat sink. The heat sink is fixedly connected to the protective cover by screws. The fan is fixedly connected to the heat sink by screws. The outer diameter of the protective net is adapted to the inner diameter of the heat sink, and the protective net is fixedly connected to the heat sink by screws.

[0019] In this invention, the combination of multiple ventilation holes helps to dissipate heat from inside the protective cover. With the cooperation of the heat sink and the fan, the fan is electrically connected to the control switch on the freeze dryer via a wire. When the control switch is turned on, the fan continuously delivers air into the protective cover, and the ventilation holes exhaust air, accelerating the dissipation of heat inside the protective cover and reducing the impact of heat accumulation.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model achieves protective cooperation between the protective cover and the fixed base on the mounting bracket by setting up a protective cover and a fixed base to protect the detection photoelectric sensor on the fixed base. Multiple airbag columns are set on the outer wall of the protective cover to reduce the impact of collisions on the protective cover, thereby increasing the protection of the detection photoelectric sensor. The front face of the protective cover is equipped with a transparent window and a lighting lamp, which allows the detection photoelectric sensor to detect reagent bottles passing by through the transparent window. The fastening bolts pass through the through holes and the screw holes for threaded connection, so as to achieve the stability of the combination of the protective cover and the fixed base.

[0022] This utility model features multiple ventilation holes, and with the heat sink and fan working together, the heat sink continuously intakes air and exhausts air through the ventilation holes, accelerating air circulation inside the protective cover, dissipating internal heat, reducing heat accumulation that could affect the continuous use of the detection photoelectric sensor. The protective net protects the end of the heat sink, reducing the entry of dust particles into the protective cover. The installation of the protective cover also prevents ambient light from interfering with the light output of the detection photoelectric sensor. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-5 This embodiment provides a technical solution:

[0036] A protective device for a detection photoelectric sensor with anti-collision and shielding functions includes a protective cover 1. A transparent window 11 is provided in the middle of the front face of the protective cover 1. Lighting lamps 12 are provided at the four corners of the transparent window 11 on the front face of the protective cover 1. Several airbag columns 2 are provided on the outer wall of the protective cover 1 except for the surface where the transparent window 11 is located. The airbag columns 2 are hollow inside and filled with air. The airbag columns 2 are evenly distributed and are bonded and fixed to the protective cover 1.

[0037] In this invention, the cooperation of multiple airbag columns 2 reduces the impact of external objects colliding with the outer surface of the protective cover 1 and reduces the impact of collision force on the protective cover 1.

[0038] Furthermore, several ventilation holes 14 are provided on the left end face of the protective cover 1 in the gap between the airbag columns 2, and a circular groove 15 is provided on the right end face of the protective cover 1. A heat dissipation device for accelerating internal ventilation is provided in the circular groove 15. A mounting bracket 4 is provided below the protective cover 1, and a fixing seat 40 is provided on the top of the mounting bracket 4. A detection photoelectric eye 41 is provided on the front end face of the fixing seat 40.

[0039] Secondly, the bottom of the fixed base 40 and the top of the mounting bracket 4 are integrally formed, and the detection photoelectric eye 41 is fixedly connected to the fixed base 40 by screws.

[0040] In this utility model, the fixed base 40 is installed near the track rail. The detection photoelectric eye 41 passes through the mounting bracket 4 via a guide and is electrically connected to the processor of the corresponding freeze dryer. The image information captured by the detection photoelectric eye 41 is transmitted to the processor of the freeze dryer for corresponding data processing.

[0041] Specifically, a screw hole 400 is provided at the center of the front end face of the fixed base 40, and a through hole 13 is provided on the front end face of the protective cover 1 at the position corresponding to the screw hole 400, and a fastening bolt 3 is provided in the through hole 13.

[0042] In this utility model, the fastening bolt 3 passes through the through hole 13 and is threadedly connected to the screw hole 400, so as to achieve a stable combination and installation of the protective cover 1 and the fixed base 40.

[0043] It should be noted that the width of the inner wall of the protective cover 1 is adapted to the width of the outer wall of the fixing seat 40. The protective cover 1 and the fixing seat 40 are plugged into each other. A handle 10 is provided at the center of the upper surface of the protective cover 1. Both ends of the handle 10 are welded and fixed to the top of the protective cover 1.

[0044] In this utility model, the handle 10 provides a point of leverage, making it easy to remove and replace the protective cover 1 from above. The protective cover 1 and the fixing base 40 are tightly inserted and fitted together, which increases the stability of the installation and reduces the gaps that may occur between the protective cover 1 and the fixing base 40 during installation. Shaking will affect the tight fit and fixation.

[0045] Furthermore, the transparent window 11 is bonded and fixed to the side wall of the protective cover 1 around its perimeter, and the lighting lamp 12 is fixedly connected to the protective cover 1 by screws.

[0046] In this invention, the transparent window 11 is made of tempered glass, allowing the photoelectric sensor 41 to detect reagent bottles passing on the conveyor track through the transparent window 11. When the track is full of reagent bottles, the photoelectric sensor 41 sends a signal to the PLC to stop the machine and wait, activating the protective discharge push rod and the feeding push rod to prevent the discharge push rod and the feeding push rod from being squeezed and deformed due to too many reagent bottles in the track, which would prevent production from being interrupted. The lighting lamp 12 is connected to the control switch on the freeze dryer through a wire, and the lighting lamp 12 is turned on, enabling the detection of reagent bottles passing on the conveyor track in a dim environment.

[0047] Specifically, the heat dissipation device includes a heat dissipation cylinder 5 and a fan 50 installed inside the heat dissipation cylinder 5, and a protective net 51 is provided at the right end of the heat dissipation cylinder 5.

[0048] It is worth noting that the ventilation holes 14 are arranged in a matrix, and the inner port of the ventilation holes 14 is higher than the outer port. The inner diameter of the circular groove 15 is adapted to the outer diameter of the heat sink 5. The heat sink 5 is fixedly connected to the protective cover 1 by screws. The fan 50 is fixedly connected to the heat sink 5 by screws. The outer diameter of the protective net 51 is adapted to the inner diameter of the heat sink 5, and the protective net 51 is fixedly connected to the heat sink 5 by screws.

[0049] In this invention, the combination of multiple ventilation holes 14 helps to dissipate heat inside the protective cover 1. With the cooperation of the heat dissipation cylinder 5 and the fan 50, the fan 50 is electrically connected to the control switch on the freeze dryer through a wire. When the control switch is turned on, the fan 50 continuously delivers air into the protective cover 1, and the ventilation holes 14 exhaust the air, accelerating the dissipation of heat inside the protective cover 1 and reducing the impact of heat accumulation.

[0050] When using the detection photoelectric eye protection device with anti-collision and shielding functions in this embodiment, firstly, the mounting bracket 4 with the fixing seat 40 is fixed near the track fence, the detection photoelectric eye 41 is fixed on the fixing seat 40, then the heat sink 5 with the fan 50 is fixed in the round groove 15 on the outer wall of the protective cover 1, the protective net 51 is fixed to the right end of the heat sink 5 with screws, then multiple airbag columns 2 filled with gas are glued and fixed to the protective cover 1 with the pull handle 10, and the transparent window 11 is combined and fixed with one side of the protective cover 1 with the lighting lamp 12.

[0051] The protective cover 1 is inserted into the mounting base 40 using the handle 10. The bottom of the protective cover 1 fits tightly against the top of the mounting bracket 4, and the fastening bolt 3 passes through the through hole 13 and is threaded into the screw hole 400, thus achieving a tight fit between the protective cover 1 and the mounting base 40. The protective cover 1 protects the internal photoelectric sensor 41. Multiple airbag columns 2 reduce the impact of overall collisions on the internal structure. The protective cover 1 covers the mounting base 40, shielding and protecting the photoelectric sensor 41. The fan 50 is activated via the control switch on the freeze dryer to achieve continuous ventilation and heat dissipation inside the protective cover 1. The four lights 12 are activated via the control switch on the freeze dryer to illuminate the area in front of the photoelectric sensor 41. The lights 12 only illuminate the reagent bottles passing in front and will not interfere with the illumination of the photoelectric sensor 41, thus avoiding the impact of dim lighting on the acquisition of images of the passing reagent bottles.
