Description

Technical Field

[0001] This utility model belongs to the field of dispensing robotic arm technology, and relates to a dispensing robotic arm for an LED automotive light module assembly dispensing machine. Background Technology

[0002] LED headlight modules are a crucial component in electric vehicles. They consist of a light panel, housing, and LEDs. During assembly, a dispensing machine is used for adhesive application and sealing. This dispensing operation relies on a robotic arm to move the dispensing section and apply adhesive to specific points on the product. However, existing robotic arms have the following drawbacks:

[0003] During the movement of the robotic arm, the dispensing tube is connected to the glue supply point, which is in a fixed position, resulting in limited mobility of the dispensing tube. In addition, there is a distance difference between the dispensing tube and the robotic arm. This causes the dispensing tube to not only interfere with the movement of the robotic arm, but also causes the glue to cool down due to the long dispensing tube, resulting in poor flowability, poor glue dispensing, and easy stringing. To address this, we designed a dispensing robotic arm for LED automotive light module assembly. Summary of the Invention

[0004] The purpose of this utility model is to provide a dispensing robotic arm for an LED vehicle light module assembly dispensing machine, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: A dispensing robotic arm for an LED automotive light module assembly dispensing machine, comprising a dispensing head mounting arm, a dispensing head, a sliding connecting block, and a dispensing solenoid valve. A fixed plate frame is provided at the bottom of the front side of the dispensing head mounting arm. The bottom end of the fixed plate frame is bolted to the dispensing solenoid valve. The dispensing head is installed at the bottom end of the dispensing solenoid valve via a threaded section. A right-angle connecting pipe is installed at the top of the fixed plate frame. An embedded flange seat is provided at one end of the right-angle connecting pipe. The interior is equipped with a heat-insulating base, and an electric heating side plate is installed on the top of the heat-insulating base. A heat-conducting jacket is installed on one end of the electric heating side plate. A heat conduction limiting sleeve is installed at the clamp of the heat-conducting jacket. A copper pipe is installed inside the heat conduction limiting sleeve. One end of the copper pipe passes through the rubber head mounting arm and is sealed to the flange of the embedded flange seat through a tapered adapter. The other end of the copper pipe passes through the top of the rubber head mounting arm and is equipped with a right-angle connector seat. A silicone hose is installed on one end of the right-angle connector seat.

[0006] In the dispensing robotic arm of the aforementioned LED automotive lighting module dispensing machine, an insertion tongue plate is provided in the middle of the back side of the dispensing head mounting arm, and an insertion slot matching the insertion tongue plate is provided in the middle of the sliding connecting block. The insertion slot and the insertion tongue plate are assembled so that the sliding connecting block is located on the back side of the dispensing head mounting arm. The purpose of this arrangement is to achieve a good assembly effect by assembling the insertion slot and the insertion tongue plate so that the sliding connecting block is located on the back side of the dispensing head mounting arm, facilitating quick and easy connection of the dispensing head mounting arm to the dispensing machine during the assembly process.

[0007] In the dispensing robotic arm of the aforementioned LED automotive lighting module dispensing machine, the top of the sliding connecting block is provided with two positioning pins, and the top of the insertion tongue plate is provided with two locking pin holes that connect with the positioning pins. This arrangement aims to increase the firmness of the connection between the sliding connecting block and the glue head mounting arm through the two positioning pins, preventing loosening and instability.

[0008] In the dispensing robotic arm of the LED automotive light module assembly dispensing machine described above, a main sliding groove is provided on the back of the sliding connecting block, and auxiliary sliding grooves are provided on the sliding connecting block at both the upper and lower parts of the main sliding groove. This design facilitates sliding installation onto the slide rail of the dispensing machine, ensuring smooth sliding motion and increasing the firmness of the connection with the slide rail.

[0009] In the dispensing robotic arm of the LED automotive light module assembly dispensing machine described above, a guide rod mounting seat is embedded at the bottom of the back of the dispensing head mounting arm. A transverse guide rod is disposed through the interior of the guide rod mounting seat, and frame mounting plates are installed at both ends of the transverse guide rod. The purpose of this arrangement is to connect the two frame mounting plates of the transverse guide rod to the dispensing machine frame, thereby ensuring good stability of the dispensing head mounting arm during transverse movement.

[0010] In the dispensing robotic arm of the dispensing machine for LED automotive light module assembly described above, a sealing connector is installed at one end of the silicone hose, and a positioning seat is provided at the end of the sealing connector. This design allows the silicone hose to be easily and quickly connected to the pipe joint of the adhesive supply system via the sealing connector and positioning seat, ensuring the stability of the connection.

[0011] Compared with existing technologies, the advantages of the dispensing robotic arm of the LED automotive lamp module assembly dispensing machine of this utility model are as follows: An electrically heated side plate is installed at the top of the heat-insulating base, and a heat-conducting jacket is installed at one end of the side plate. A heat-conducting limiting sleeve is installed at the clamp of the heat-conducting jacket. A copper pipe is installed inside the heat-conducting limiting sleeve, which can heat the copper pipe, preventing the adhesive flowing inside from cooling and reducing its fluidity. This avoids poor fluidity, uneven dispensing, and stringing. Simultaneously, the copper pipe located inside the dispensing head mounting arm reduces movement interference, facilitating better movement of the dispensing head mounting arm. A guide rod mounting seat is embedded at the bottom of the back of the dispensing head mounting arm, and a transverse guide rod is installed through the inside of the guide rod mounting seat. The two frame mounting plates of the transverse guide rod are connected to the dispensing machine frame, giving the dispensing head mounting arm good stability during lateral movement.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a dispensing robotic arm for an LED vehicle light module assembly dispensing machine.

[0019] Example: The dispensing robotic arm includes a dispensing head mounting arm 1, a dispensing head 2, a sliding connecting block 3, and a dispensing solenoid valve 7. A fixing frame 6 is installed at the bottom of the front of the dispensing head mounting arm 1. The bottom end of the fixing frame 6 is bolted to the dispensing solenoid valve 7. The dispensing head 2 is installed at the bottom end of the dispensing solenoid valve 7 via a threaded section. A right-angle connecting pipe 5 is installed at the top of the fixing frame 6. One end of the right-angle connecting pipe 5 is equipped with an embedded flange seat 4. A heat-insulating base 23 is installed inside the dispensing head mounting arm 1. An electrically heated side plate 20 is installed at the top of the heat-insulating base 23. A heat-conducting jacket 21 is installed at one end, and a heat conduction limiting sleeve 22 is installed at the clamp of the heat-conducting jacket 21. A copper pipe 19 is installed inside the heat conduction limiting sleeve 22. One end of the copper pipe 19 passes through the glue head mounting arm 1 and is sealed to the flange of the embedded flange seat 4 through the tapered adapter 18. The electric heating side plate 20 generates heat when energized, which can heat the copper pipe 19, so that the glue flowing inside the copper pipe 19 can be heated to avoid cooling and reduced fluidity, thereby avoiding poor fluidity, poor glue dispensing, and easy stringing.

[0020] Based on the embodiment, in order to facilitate quick and easy connection to the glue supply system of the dispensing machine, the other end of the copper pipe 19 passes through the top of the glue head mounting arm 1 and is equipped with a right angle connector seat 8. A silicone hose 9 is installed at one end of the right angle connector seat 8; a sealing connector 10 is installed at one end of the silicone hose 9, and a positioning seat 11 is provided at the end of the sealing connector 10.

[0021] Furthermore, based on the embodiment, in order to facilitate the assembly of the glue head mounting arm 1 and the sliding connecting block 3, and to enable the glue head mounting arm 1 to be quickly assembled with the dispensing machine, an insertion tongue plate 12 is provided in the middle of the back of the glue head mounting arm 1, and an insertion groove 13 matching the insertion tongue plate 12 is provided in the middle of the sliding connecting block 3. The insertion groove 13 and the insertion tongue plate 12 are assembled so that the sliding connecting block 3 is located on the back of the glue head mounting arm 1; two positioning pins 14 are provided at the top of the sliding connecting block 3, and two locking pin holes 15 connected to the positioning pins 14 are provided at the top of the insertion tongue plate 12.

[0022] Furthermore, in order to better slide and install it onto the slide rail of the dispensing machine, ensure smooth sliding motion, and increase the firmness of the connection with the slide rail, a main sliding groove 16 is provided on the back of the sliding connecting block 3, and auxiliary sliding grooves 17 are provided on the upper and lower parts of the main sliding groove 16.

[0023] Example 2: A guide rod mounting seat 24 is embedded at the bottom of the back of the glue head mounting arm 1. A transverse guide rod 25 is provided through the inside of the guide rod mounting seat 24. A frame mounting plate 26 is installed at both ends of the transverse guide rod 25. In this way, the two frame mounting plates 26 of the transverse guide rod 25 are connected to the dispensing machine frame, so that the glue head mounting arm 1 has good stability during transverse movement and ensures a good movement trajectory.

[0024] In use: Install the sliding connecting block 3 onto the slide rail of the dispensing machine through the main sliding slot 16 and the auxiliary sliding slot 17 to move the glue head mounting arm 1 left and right. Then connect the silicone hose 9 to the glue supply system of the dispensing machine through the sealing connector 10 and the positioning seat 11. The glue supply system supplies the glue liquid. The glue liquid enters the right-angle connecting pipe 5 and the dispensing solenoid valve 7 through the copper pipe 19, and finally enters the dispensing head 2 to perform the dispensing operation. The electric heating side plate 20 of this solution generates heat when energized, which can heat the copper pipe 19, so that the glue liquid flowing inside the copper pipe 19 can be heated to avoid cooling and reduced fluidity, thereby avoiding poor fluidity, poor glue dispensing, and easy stringing.
