Description

Technical Field

[0001] This utility model relates to the field of automotive lamp annealing technology, specifically to an automotive lamp annealing device. Background Technology

[0002] During the injection molding process of automotive headlights, internal stress is generated. Before painting, the headlights must undergo stress relief treatment, otherwise they may crack.

[0003] A search revealed that China published patent publication number CN216584719U on May 24, 2022, regarding an annealing furnace for automotive headlight glass covers. The furnace is described as comprising a furnace body and a conveying mechanism. The furnace body, along the conveying direction, consists of a low-temperature section, a high-temperature section, and a cooling section. The low-temperature section has independently controlled low-temperature heating zones on the top and sides, equipped with corresponding low-temperature thermocouples for monitoring. The high-temperature section also has independently controlled high-temperature heating zones on the top and sides, equipped with corresponding high-temperature thermocouples for monitoring. A bottom auxiliary heating zone is located below the conveying mechanism.

[0004] Although the existing technical solution described above can ensure the annealing quality of the headlight glass cover by setting up multiple independent heating zones for the low temperature / high temperature sections, the device is not conducive to uniform feeding, resulting in different spacing of materials during annealing, which can easily lead to a reduction in the annealing effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a vehicle headlight annealing device to solve the problem mentioned in the background technology that makes it difficult to feed materials evenly, resulting in different spacing of materials during annealing and easily leading to a reduction in the annealing effect.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vehicle headlight annealing device, comprising a furnace body and a transport box.

The furnace body has an internal feeding zone, a low-temperature zone, a high-temperature zone, and a discharging zone. Heating plates are installed inside the low-temperature zone and the high-temperature zone. Two blower fans, each cooperating with a heating plate, are installed on the upper inner side wall of the furnace body. Three evenly distributed partition plates are fixedly connected inside the furnace body, separating the feeding zone, the low-temperature zone, the high-temperature zone, and the discharging zone. Two cooperating drive rollers are rotatably connected inside the furnace body, and a drive belt is connected between the two drive rollers, passing through the three partition plates. Each of the partition plates has a feed port, the upper part of the transmission belt passes through the feed port, a first motor connected to the transmission roller is installed on the outer wall of the furnace body, one end of the transport box is fixedly connected to the feeding area, one end of the transport box has a discharge port through the furnace body, the transport box has a discharge port at the bottom inside the feeding area, two rotating rollers are rotatably connected inside the transport box, a transport belt is driven between the two rotating rollers, multiple evenly distributed actuating plates are fixedly connected to the transport belt, a second motor connected to the rotating roller is installed on the outer wall of the transport box, a second support leg connected to the bottom plate is fixedly connected to the bottom of the transport box, a discharge port is opened at the end of the furnace body near the discharge area, and a collection box that matches the discharge port is fixedly connected to the top of the bottom plate.

[0009] By adopting the above technical solution, the first motor and the second motor are started. At this time, multiple car lights are put into the feeding port, and multiple actuating plates drive multiple car lights to move at a uniform speed in sequence. This allows multiple car lights to fall onto the transmission belt at a uniform speed from the discharge port, so that multiple car lights maintain the same spacing. This allows the transmission belt to drive the car lights through the low temperature zone and the high temperature zone. Finally, the car lights fall into the collection box through the discharge port, thereby annealing the car lights.

[0010] Optionally, the bottom of the transport box is fixedly connected to a first guide that matches the discharge port, and the inside of the furnace body is fixedly connected to a second guide that matches the discharge port. One end of the second guide is located below the transmission belt, and the other end of the second guide is located above the collection box.

[0011] By adopting the above technical solution, when the headlight falls from the discharge port, the first guide is used to slide and buffer the headlight at an angle, and when the headlight falls from the transmission belt, the second guide is used to slide and buffer the headlight at an angle, so that the headlight can fall into the collection box through the discharge port, thereby reducing the impact on the headlight and reducing the probability of headlight deformation and damage.

[0012] Optionally, baffles are rotatably connected to the feed ports of the three partition plates.

[0013] By adopting the above technical solution, the baffle is used to facilitate the passage of vehicle lights through the material inlet while blocking the material inlet to prevent heat loss and reduce resource waste.

[0014] Optionally, a cushioning pad is provided on the inner wall of the collection box.

[0015] By adopting the above technical solution, when the headlight falls into the collection box, the buffer pad is used to cushion the headlight, thereby reducing the probability of the headlight being damaged by impact.

[0017] By adopting the above technical solution, two temperature sensors are used to sense the temperature in the low-temperature zone and the high-temperature zone respectively, so as to display the temperature in the low-temperature zone and the high-temperature zone on the display screen in real time. This makes it convenient for personnel to observe the temperature inside the furnace in real time. Based on the temperature inside the furnace, the staff can control the temperature of the heating plate through the controller, thus making it convenient for personnel to control the temperature inside the furnace.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] The vehicle headlight annealing device starts the first and second motors, at which point multiple vehicle headlights are fed into the feeding port. This causes multiple actuating plates to sequentially move the multiple headlights at a uniform speed, so that the multiple headlights fall uniformly from the discharge port onto the transmission belt. This ensures that the multiple headlights maintain the same spacing, and the transmission belt moves the headlights through the low-temperature zone and the high-temperature zone. Finally, the headlights fall into the collection box through the discharge port, thus annealing the headlights. This device facilitates uniform feeding and improves the annealing effect.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4An annealing device for vehicle headlights includes a furnace body 1 and a transport box 2. First support legs 3 are fixedly connected to the four corners of the bottom of the furnace body 1. A base plate 4 is fixedly connected to the bottom of each of the four first support legs 3. The furnace body 1 has an internal feeding zone 5, a low-temperature zone 6, a high-temperature zone 7, and a discharge zone 8. Heating plates 9 are installed inside the low-temperature zone 6 and the high-temperature zone 7. Two blower fans 10 are installed on the upper inner side wall of the furnace body 1, each cooperating with one of the two heating plates 9. Three evenly distributed partition plates 11 are fixedly connected inside the furnace body 1. 1 is used to separate the feeding zone 5, the low-temperature zone 6, the high-temperature zone 7, and the discharge zone 8. Two cooperating drive rollers 12 are rotatably connected inside the furnace body 1. A drive belt 13 is connected between the two drive rollers 12, and the drive belt 13 passes through three partition plates 11. Each of the three partition plates 11 has a material passage opening. The upper part of the drive belt 13 passes through the material passage opening. A first motor 14 connected to the drive rollers 12 is installed on the outer wall of the furnace body 1. One end of the transport box 2 is fixedly connected to the feeding zone 5, and the other end of the transport box 2 passes through the furnace body 1 and has a discharge opening. The transport box 2 has a discharge port at its bottom inside the feeding area 5. Two rotating rollers 15 are rotatably connected inside the transport box 2, and a conveyor belt 16 is driven between the two rollers 15. Multiple evenly distributed actuating plates 17 are fixedly connected to the conveyor belt 16. A second motor 18 connected to the rotating rollers 15 is installed on the outer wall of the transport box 2. A second support leg 19 connected to the bottom plate 4 is fixedly connected to the bottom of the transport box 2. The furnace body 1 has a discharge port at one end near the discharge area 8, and a matching discharge port is fixedly connected to the top of the bottom plate 4. The first motor 14 and the second motor 18 are started in the collection box 20. At this time, multiple car lights are put into the discharge port, so that multiple actuating plates 17 drive multiple car lights to move at a uniform speed in sequence. This allows multiple car lights to fall from the discharge port onto the transmission belt 13 at a uniform speed, so that multiple car lights maintain the same spacing. This allows the transmission belt 13 to drive the car lights through the low temperature zone 6 and the high temperature zone 7. Finally, the car lights fall into the collection box 20 through the discharge port, thereby annealing the car lights. This makes the equipment easier to feed evenly and achieves the purpose of improving the annealing effect.

[0029] Reference Figure 2 and Figure 3 The bottom of the transport box 2 is fixedly connected to a first guide 21 that cooperates with the discharge port. The inside of the furnace body 1 is fixedly connected to a second guide 22 that cooperates with the discharge port. One end of the second guide 22 is located below the transmission belt 13, and the other end of the second guide 22 is located above the collection box 20. When the headlight falls from the discharge port, the first guide 21 is used to slide and buffer the headlight at an angle. When the headlight falls from the transmission belt 13, the second guide 22 is used to slide and buffer the headlight at an angle, so that the headlight can fall into the collection box 20 through the discharge port, thereby reducing the impact on the headlight and reducing the probability of headlight deformation and damage.

[0030] Reference Figure 3 and Figure 4 Each of the three partition plates 11 has a baffle 23 rotatably connected to its material passage. The baffle 23 is used to facilitate the passage of the vehicle lights while blocking the material passage to prevent heat loss and reduce waste of resources.

[0031] Reference Figure 1 and Figure 3 The inner wall of the collection box 20 is provided with a buffer pad 24. When the headlight falls into the collection box 20, the buffer pad 24 is used to cushion the headlight, thereby reducing the probability of the headlight being damaged by impact.

[0032] Reference Figures 1-4 Two temperature sensors 25 are installed on the outer wall of the furnace body 1. The probes of the two temperature sensors 25 are respectively connected to the interior of the low-temperature zone 6 and the high-temperature zone 7. A display screen 26 and a controller 27 are installed on the outer wall of the furnace body 1. The display screen 26 is electrically connected to the two temperature sensors 25, and the controller 27 is electrically connected to the two heating plates 9. The two temperature sensors 25 are used to sense the temperature in the low-temperature zone 6 and the high-temperature zone 7, respectively, so as to display the temperature in the low-temperature zone 6 and the high-temperature zone 7 on the display screen 26 in real time. This makes it convenient for personnel to observe the temperature inside the furnace body 1 in real time. Based on the temperature inside the furnace body 1, the personnel can control the temperature of the heating plates 9 through the controller 27, thus making it convenient for personnel to control the temperature inside the furnace body 1.

[0033] It should be further explained that the first motor 14, the second motor 18, the temperature sensor 25, the display screen 26, and the controller 27 in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. The first motor 14, the second motor 18, the temperature sensor 25, the display screen 26, and the controller 27 are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage needs to facilitate operation and control by the operator.

[0034] In summary, the working principle and process of this vehicle headlight annealing device are as follows: First, the first motor 14 and the second motor 18 are started. Multiple vehicle headlights are then fed into the discharge port, causing multiple actuating plates 17 to sequentially move the headlights at a uniform speed. This allows the headlights to fall uniformly from the discharge port onto the transmission belt 13, maintaining the same spacing between them. The transmission belt 13 then carries the headlights through the low-temperature zone 6 and the high-temperature zone 7. Finally, the headlights fall through the discharge port into the collection box 20, thus annealing the headlights. This facilitates uniform feeding and improves the annealing effect. When the headlights fall from the discharge port, the first guide member 21 provides oblique sliding buffering; when the headlights fall from the transmission belt 13, the second guide member 22 provides oblique sliding buffering, facilitating the movement of the headlights. The headlights fall into the collection box 20 through the discharge port, thereby reducing the impact on the headlights and lowering the probability of headlight deformation and damage. The baffle 23 is used to facilitate the headlights to pass through the discharge port while blocking the discharge port to prevent heat loss and reduce resource waste. When the headlights fall into the collection box 20, the buffer pad 24 is used to cushion the headlights, thereby reducing the probability of headlights being damaged by impact. Two temperature sensors 25 are used to sense the temperature in the low temperature zone 6 and the high temperature zone 7, respectively, and display the temperature in the low temperature zone 6 and the high temperature zone 7 on the display screen 26 in real time, so that personnel can observe the temperature inside the furnace body 1 in real time. Based on the temperature inside the furnace body 1, the staff can control the temperature of the heating plate 9 through the controller 27, so as to facilitate the control of the temperature inside the furnace body 1.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
