Description

Technical Field

[0001] This utility model relates to the field of lens manufacturing equipment, and in particular to a feeding device for TV lenses. Background Technology

[0002] TV lenses, or television lenses, are primarily used in backlight systems for lighting equipment such as television backlights, advertising light boxes, and panel lights. They work by diffusing and homogenizing light emitted from a light source through optical principles, thereby improving lighting effects and enhancing visual comfort. The production process of TV lenses involves multiple precision steps, including fine grinding, polishing, edging, core setting, and cleaning. Finally, a comprehensive quality inspection is conducted using a combination of machine and manual checks. Through rigorous production processes and quality control, the quality and performance of TV lenses can be ensured to meet various application requirements.

[0003] Through extensive practical experience, the inventors discovered that currently, when TV lenses are unloaded after processing, they typically detach after the robotic arm moves above the material box and then fall directly into the box. To ensure production efficiency, the robotic arm needs to feed and reset quickly. When the robotic arm moves above the material box, the TV lens is not cooled down and is easily scratched after impact. On the other hand, to avoid frequent material box changes, the material box has a certain depth, and there is a certain distance between the robotic arm and the bottom of the material box. It is difficult to avoid collisions between the TV lens and the bottom of the material box or with other TV lenses inside the material box. Therefore, the unloading process of TV lenses often produces defective products. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a TV lens unloading device. By using a conveyor belt for receiving the lenses, the robotic arm can place the TV lenses stably on the conveyor belt at a lower height, effectively avoiding damage and scratches to the TV lenses. Furthermore, since the conveyor belt runs continuously, collisions between TV lenses are effectively avoided. In addition, the process of the TV lenses moving from one end of the conveyor belt to the other end extends their cooling time. Moreover, the TV lenses are cooled more effectively by the fan when passing through the conveyor belt in the processing area. Therefore, the TV lenses are already cooled when they fall from the conveyor belt to the receiving part, making them less prone to scratches or damage, and effectively reducing the defect rate of TV lenses.

[0005] A TV lens unloading device includes a bracket, a conveyor belt, a receiving part, a fan, and a drive motor for driving the conveyor belt. The conveyor belt is fixed on the bracket. The unloading device has an unloading area, a processing area, and a discharge area arranged sequentially along the conveying direction at the conveyor belt. The TV lens falls on the conveyor belt in the unloading area. The receiving part is located at the end of the conveyor belt. One end of the receiving part is fixed to the bracket, and the other end of the receiving part is inclined downwards from the conveyor belt. The fan is located in the processing area and fixed to the bracket. The fan is oriented towards the conveyor belt. The drive motor is fixed on the bracket.

[0006] The TV lens unloading device described in this utility model uses a conveyor belt for receiving, allowing the robotic arm to place the TV lens stably on the conveyor belt at a lower height, effectively avoiding damage and scratches to the TV lens. Furthermore, the continuous operation of the conveyor belt effectively prevents collisions between TV lenses. In addition, the process of the TV lens moving from one end of the conveyor belt to the other end extends its cooling time. Moreover, the TV lens receives more effective cooling under the action of the fan when passing through the conveyor belt in the processing area. Therefore, the TV lens is already cooled when it falls from the conveyor belt to the receiving part, making it relatively less prone to scratches or damage, effectively reducing the defect rate of TV lenses.

[0007] Furthermore, the fan is located above the conveyor belt, with its output end facing the conveyor belt in the processing area. This direct airflow from the fan directly onto the conveyor belt in the processing area effectively cools the TV lenses passing through it, resulting in a good cooling effect.

[0008] Furthermore, it also includes a negative pressure chamber located in the processing area and covering the conveyor belt. The negative pressure chamber has at least two through holes at the location where the TV lens passes. The conveyor belt has several air holes, and the fan is located below the conveyor belt with its input end facing the conveyor belt. By setting up the negative pressure chamber and opening the air holes on the conveyor belt, a negative pressure is created inside the negative pressure chamber by the fan. This creates an airflow that flows into the negative pressure chamber through the two through holes, exits through the air holes on the conveyor belt, and is blown out by the output end of the fan. This airflow cools the TV lens inside the negative pressure chamber, which helps reduce dust generated by the fan.

[0009] Furthermore, the angle between the receiving part and the horizontal plane is 31~33°. This angle facilitates the smooth and even sliding of the TV lens off the receiving part.

[0010] Furthermore, the fan is an ion fan. Using an ion fan can effectively remove dust, preventing dust from affecting product quality.

[0011] Furthermore, it also includes several dust removal units, which are located below and close to the conveyor belt, and are fixed to the support frame. The dust removal units remove dust from the conveyor belt, preventing dust from affecting product quality.

[0012] Furthermore, it also includes several antistatic units located below and close to the conveyor belt, and fixed to the bracket. The antistatic units remove any static electricity that may be present on the conveyor belt, preventing dust from being attracted to the conveyor belt due to static electricity.

[0013] Furthermore, the conveyor belt is a metal conveyor belt. Using a metal conveyor belt provides good thermal conductivity, which is beneficial for cooling the TV lens.

[0014] Furthermore, it also includes a receiving bag, the opening of which is fitted over the lower end of the receiving part and detachably fixed to the receiving part. Using a bag to receive the TV lens prevents damage to the TV lens from impacts.

[0015] Furthermore, the support is a telescopic support, and the direction of its extension and retraction is perpendicular to the ground. The telescopic support facilitates adjustment of the distance between the TV lens held by the robotic arm and the conveyor belt, ensuring that the TV lens is not damaged or scratched when it falls onto the conveyor belt.

[0016] The beneficial effects of this application are as follows:

[0017] 1. Using a conveyor belt for receiving allows the robotic arm to place TV lenses stably on the conveyor belt at a lower height, effectively preventing damage from impacts and scratches. Furthermore, the continuous operation of the conveyor belt effectively prevents collisions between TV lenses. Additionally, the movement of the TV lenses from one end of the conveyor belt to the other extends their cooling time, and the fans further enhance cooling as the lenses pass through the processing area. Therefore, the TV lenses are already cooled before falling from the conveyor belt to the receiving area, making them less prone to scratches or impacts and effectively reducing the defect rate of TV lenses.

[0018] 2. The fan blows directly onto the conveyor belt in the processing area, cooling the TV lenses passing through the processing area through direct blowing, resulting in a good cooling effect.

[0019] 3. A negative pressure box is set up and air holes are opened on the conveyor belt. A negative pressure is formed in the negative pressure box by the fan, which in turn forms an airflow that flows into the negative pressure box from the two through holes and exits the negative pressure box from the air holes on the conveyor belt and is blown out by the output end of the fan. The airflow cools the TV lens in the negative pressure box, which helps to reduce the dust generated by the fan.

[0020] 4. This angle allows the TV lens to slide smoothly and gently off the receiving section.

[0021] 5. Using an ion fan can effectively remove dust and prevent dust from affecting product quality.

[0022] 6. Install a dust removal unit to remove dust from the conveyor belt and prevent dust from affecting product quality.

[0023] 7. Install an anti-static unit to remove any static electricity that may be present on the conveyor belt, preventing the conveyor belt from attracting dust due to static electricity.

[0024] 8. The use of a metal conveyor belt has good thermal conductivity, which is beneficial for cooling down the TV lens.

[0025] 9. Use a bag to hold the TV lens to avoid damaging it.

[0026] 10. A telescopic support is provided to facilitate adjustment of the distance between the TV lens held by the robotic arm and the conveyor belt, ensuring that the TV lens will not be damaged or scratched when it falls onto the conveyor belt.

[0039] This utility model provides a TV lens feeding device. Please refer to [link to relevant documentation]. Figure 1The device includes a support frame 1, a conveyor belt 2, a negative pressure box 3, a receiving section 4, a fan 5, and a drive motor 6 for driving the conveyor belt 2. The conveyor belt 2 is fixed to the support frame 1 and has several air holes on its belt body for conveying. The TV lens unloading device has an unloading area, a processing area, and a discharge area arranged sequentially along the conveying direction at the conveyor belt 2. The unloading area is located at the starting end of the conveyor belt 2 and is used to receive the TV lenses transported by the robotic arm. The TV lenses fall onto the conveyor belt 2 in the unloading area. The processing area is used to cool the TV lenses. The negative pressure box 3 is located in the processing area and covers the conveyor belt 2. The negative pressure box 3 has two through holes at the position where the TV lenses pass through, to ensure that the TV lenses can pass through normally. The pressure chamber 3, on the other hand, serves as the air inlet of the negative pressure chamber 3. The receiving part 4 is located at the end of the conveyor belt 2. One end of the receiving part 4 is fixed to the bracket 1, and the other end is inclined downwards towards the conveyor belt 2. After the TV lens falls from the end of the conveyor belt 2 to the receiving part 4, it continues to slide downwards along the inclined receiving part 4 and falls into the container for receiving the material. The fan 5 is located in the processing area and is fixed to the bracket 1 below the conveyor belt 2. The input end of the fan 5 is set towards the conveyor belt 2. When the fan 5 is running, it draws the air in the negative pressure chamber 3 out from below the conveyor belt 2 through the through hole on the conveyor belt 2 to form a negative pressure in the negative pressure chamber 3. The drive motor 6 is fixed on the bracket 1 and is connected to the conveyor belt 2 to drive the conveyor belt 2 to run. This utility model embodiment of a TV lens unloading device uses a conveyor belt 2 for receiving, allowing the robotic arm to place the TV lens stably on the conveyor belt 2 at a lower height, effectively avoiding damage and scratches to the TV lens. Furthermore, since the conveyor belt 2 runs continuously, it effectively avoids collisions between TV lenses. In addition, the process of the TV lens moving from one end of the conveyor belt 2 to the other end of the conveyor belt 2 can extend its cooling time. On the other hand, when the TV lens passes through the processing area conveyor belt 2, it is cooled more effectively by the action of the fan 5. Therefore, the TV lens has been cooled when it falls from the conveyor belt 2 to the receiving part 4, making it relatively less prone to scratches or damage, effectively reducing the defect rate of TV lenses.

[0040] For further details in one embodiment, please refer to [link / reference]. Figure 2 The TV lens unloading device also includes several dust removal units 77, which are located below and close to the conveyor belt 2 and are fixed to the bracket 1. The dust removal units 77 are installed to remove dust from the conveyor belt 2, preventing dust from affecting product quality.

[0041] For further details in one embodiment, please refer to [link / reference]. Figure 3The TV lens unloading device also includes several antistatic units 8, which are located below and close to the conveyor belt 2 and are fixed to the bracket 1. The antistatic units 8 are provided to remove any static electricity that may be present on the conveyor belt 2, preventing the conveyor belt 2 from attracting dust due to static electricity.

[0042] In one embodiment, please refer to further details. Figure 4 The support 1 of the TV lens unloading device is a telescopic support, and the telescopic support extends and retracts perpendicular to the ground. The telescopic support is set up to facilitate the adjustment of the distance between the TV lens held by the robotic arm and the conveyor belt 2, so as to ensure that the TV lens will not be damaged or scratched when it falls onto the conveyor belt 2.

[0043] In one embodiment, the angle between the inclined surface of the receiving part 4 that contacts the TV lens and the horizontal surface is 32°. In other embodiments, the angle can be 31 to 33°, which is conducive to the TV lens sliding smoothly and gently off the receiving part 4.

[0044] In one embodiment, the fan 5 is an ion fan to effectively remove dust and prevent dust from affecting product quality.

[0045] In one embodiment, the conveyor belt 2 is a metal conveyor belt. Metal conveyor belts have good thermal conductivity, which is beneficial for cooling down the TV lens.

[0046] In one embodiment, the TV lens feeding device further includes a receiving bag. The opening of the receiving bag is sleeved on the lower end of the receiving part 4 and detachably fixed to the receiving part 4. The bag is used as the receiving container for the TV lens to avoid damage to the TV lens due to collision with the receiving container.

[0047] In one embodiment, please refer to further details. Figure 5 The TV lens feeding device may not include the negative pressure box 3. In this case, the fan 5 is located above the conveyor belt 2, and the output end of the fan 5 is set towards the conveyor belt 2 in the processing area, so that the fan 5 blows directly onto the conveyor belt 2 in the processing area. The TV lens passing through the processing area is cooled by direct blowing, and the cooling effect is good.

[0048] The beneficial effects of this application are as follows:

[0049] 1. The use of conveyor belt 2 for receiving allows the robotic arm to place the TV lens stably on it at a lower height, effectively preventing damage from impacts and scratches. Furthermore, the continuous operation of conveyor belt 2 effectively prevents collisions between TV lenses. Additionally, the movement of the TV lens from one end of conveyor belt 2 to the other extends its cooling time. Moreover, the TV lens receives more effective cooling under the action of fan 5 as it passes through the processing area conveyor belt 2. Therefore, the TV lens is already cooled when it falls from conveyor belt 2 to receiving section 4, making it less prone to scratches or impacts and effectively reducing the defect rate of TV lenses.

[0050] 2. The fan 5 blows directly onto the conveyor belt 2 in the processing area, cooling the TV lens passing through the processing area through direct blowing, resulting in a good cooling effect.

[0051] 3. A negative pressure box 3 is set up and air holes are opened on the conveyor belt 2. A negative pressure is formed in the negative pressure box 3 by the fan 5, which in turn forms an airflow that flows into the negative pressure box 3 from the two through holes of the negative pressure box 3 and exits the negative pressure box 3 from the air holes on the conveyor belt 2 and is blown out by the output end of the fan 5. The TV lens in the negative pressure box 3 is cooled by the airflow, which helps to reduce the dust generated by the fan 5.

[0052] 4. This angle facilitates the smooth and gentle sliding of the TV lens off the receiving section 4.

[0053] 5. Using an ion fan can effectively remove dust and prevent dust from affecting product quality.

[0054] 6. A dust removal unit 77 is installed to remove dust from the conveyor belt 2 to prevent dust from affecting product quality.

[0055] 7. An anti-static unit 8 is installed to remove any static electricity that may be present on the conveyor belt 2, preventing the conveyor belt 2 from attracting dust due to static electricity.

[0056] 8. The use of a metal conveyor belt has good thermal conductivity, which is beneficial for cooling down the TV lens.

[0057] 9. Use a bag to hold the TV lens to avoid damaging it.

[0058] 10. A telescopic bracket is provided to facilitate adjustment of the distance between the TV lens held by the robotic arm and the conveyor belt 2, ensuring that the TV lens will not be damaged or scratched when it falls onto the conveyor belt 2.

[0059] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
