Description

Technical Field

[0001] This utility model relates to the field of automotive lamp welding technology; more specifically, it relates to a support device for welding automotive lamp plastic shells. Background Technology

[0002] The headlight housing is the outer shell structure of the headlight, mainly serving to protect the internal circuitry, light source, and heat dissipation system. Its material, manufacturing process, and design directly affect the headlight performance.

[0003] Welding of automotive headlight housings is a key process in automotive headlight manufacturing. It is mainly used to firmly connect different plastic parts such as lamp covers, lamp bodies, and decorative frames to ensure sealing, structural strength, and optical performance.

[0004] Currently, existing support devices have several drawbacks. Most require molds and ultrasonic welding to weld the headlights, necessitating mold replacement depending on the headlight size. Existing molds, often threaded, are cumbersome to change, and their fixed thread positions hinder accurate positioning based on size, reducing usability. Furthermore, many devices require mold cooling, which is inconvenient for connecting to water tanks, potentially impacting production speed and further compromising usability. Therefore, a new support device for welding headlight plastic shells is urgently needed to address these issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a support device for welding plastic shells of vehicle lights, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a support device for welding plastic shells of automotive lights, comprising: a base, a buffer pad fixedly connected to the upper end of the base, and a placement seat fixedly connected to the upper end of the buffer pad, and a clamping and positioning structure provided inside the upper outer surface of the placement seat, a mold attached to the upper outer surface of the placement seat, a hydraulic rod installed on one side of the upper outer surface of the base, and a support plate fixedly connected to the upper end of the hydraulic rod, and an ultrasonic plastic welding machine installed on the surface of one bottom end of the support plate, and a quick-connect structure provided on one side of the outer surface of the mold; the clamping and positioning structure includes a moving groove, a lead screw, a clamping block and a positioning groove; the quick-connect structure includes a first connecting pipe, a second connecting pipe, a movable groove, a movable plate, a spring, a water tank, a water pump, an output pipe, an input pipe, a mating interface and a positioning hole.

[0007] Preferably, the movable groove is opened inside the upper outer surface of the placement seat, and the inner bearings of the inner wall surfaces at both ends of the movable groove are connected to lead screws, and clamping blocks are sleeved on the outer surfaces of both ends of the lead screws. The inner surfaces of the outer surfaces at both ends of the mold are all positioning grooves. This design allows the two sets of clamping blocks to move on the outer surfaces of the lead screws.

[0008] Preferably, the threads on the outer surfaces of both ends of the lead screw are designed to be opposite to each other. The outer surfaces of the upper ends of the two sets of clamping blocks are fixedly connected to engaging blocks, and the external dimensions of the engaging blocks are the same as the internal dimensions of the positioning grooves. The inner wall surfaces on both sides of the moving groove are fixedly connected to rectangular blocks. Rectangular grooves are opened on both sides of the clamping blocks, and the internal dimensions of the rectangular grooves are adapted to the external dimensions of the rectangular blocks. This design allows the two sets of clamping blocks to move outward or inward synchronously on the outer surface of the lead screw.

[0009] Preferably, a first connecting pipe is connected to one side of the outer surface of the mold, and a second connecting pipe is connected to one side of the outer surface of the mold. Movable grooves are formed inside the outer surfaces of both ends of the first and second connecting pipes, and movable plates are engaged inside the movable grooves. Springs are provided inside the movable grooves. A water tank is fixedly connected to one side of the outer surface of the movable groove, and a water pump is installed inside the water tank. An output pipe is connected to the output end of the water pump. The upper end of the output pipe is engaged inside the outer surface of one side of the upper end of the output pipe, and an input pipe is engaged inside the outer surface of the other side of the upper end of the water tank. A mating interface is formed inside the outer surfaces of the upper ends of the output pipe and the input pipe, and positioning holes are formed inside the inner walls of both sides of the mating interface. This design allows the water pump to draw water stored inside the output pipe and allow the stored water to enter the interior of the second connecting pipe through the output pipe, thereby cooling the interior of the mold.

[0010] Preferably, a positioning block is fixedly connected to the outer surface of one side of the lower end of the movable plate, and the external dimensions of the positioning block are adapted to the internal dimensions of the positioning hole. The external dimensions of one end of the first connecting pipe and the second connecting pipe are adapted to the internal dimensions of the mating interface. An insertion rod is fixedly connected to the outer surface of one end of the first connecting pipe and the second connecting pipe, and the insertion rod is made of rubber. This design makes the movable plate more stable when it is engaged in the interior of the positioning hole.

[0011] Preferably, the two ends of the spring abut against the surface of the other side of the movable plate and the inner wall surface of the movable groove, respectively. A plug is inserted into the inner surface of the upper outer surface of the water tank. By pulling the plug upward, water can be added to the inside of the water tank.

[0012] The technical effects and advantages of this utility model are as follows: By rotating the lead screw, the two sets of clamping blocks can move outward or inward from the outer surface of the lead screw. This allows the mold to be clamped and positioned by the two sets of clamping blocks. The locking block at the upper end of the clamping block engages with the inside of the positioning groove, thereby positioning the mold on the outer surface of the upper end of the placement seat. This facilitates the positioning of molds of different sizes and eliminates the need for bolts to position the mold, making it more convenient to use and improving the practicality of the device to a certain extent.

[0013] By inserting one end of the first connecting pipe and the second connecting pipe into the two sets of mating interfaces, the connection between the mold and the water tank can be quickly completed. At this time, the water pump can be started to draw the stored water in the water tank and let the stored water enter the mold through the second connecting pipe and circulate back into the water tank through the first connecting pipe. This can avoid affecting the production rate of the device and improve the practicality of the device to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The vehicle lamp welding involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1, as Figures 1-4 As shown, this embodiment proposes a support device for welding automotive headlight plastic shells, including: a base 1, a buffer pad 2 fixedly connected to the upper end of the base 1, and a placement seat 3 fixedly connected to the upper end of the buffer pad 2. A clamping and positioning structure 4 is provided inside the upper outer surface of the placement seat 3. A mold 5 is attached to the upper outer surface of the placement seat 3. A hydraulic rod 6 is installed on one side of the upper outer surface of the base 1, and a support plate 7 is fixedly connected to the upper end of the hydraulic rod 6. An ultrasonic plastic welding machine 8 is installed on the surface of one bottom end of the support plate 7. A quick-connect structure 9 is provided on one side of the outer surface of the mold 5. The clamping and positioning structure 4 includes a moving groove 41, a lead screw 42, a clamping block 43, and a positioning groove 44. The moving groove 41 is opened inside the upper outer surface of the placement seat 3, and the lead screw 42 is connected to the inner bearings of the inner walls at both ends of the moving groove 41. Clamping blocks 43 are sleeved on the outer surfaces of both ends of the lead screw 42. The mold 5 has a quick-connect structure 9 on one side of the outer surface. The inner surface of each mold 42 has a positioning groove 44. The threads on the outer surfaces of both ends of the lead screw 42 are designed with opposite threads. The outer surfaces of the upper ends of the two sets of clamping blocks 43 are fixedly connected with locking blocks, and the outer dimensions of the locking blocks are the same as the inner dimensions of the positioning groove 44. The inner wall surfaces on both sides of the moving groove 41 are fixedly connected with rectangular blocks. The clamping blocks 43 have rectangular grooves on both sides, and the inner dimensions of the rectangular grooves are compatible with the outer dimensions of the rectangular blocks. This design allows the two sets of clamping blocks 43 to move outward or inward from the outer surface of the lead screw 42 by rotating the lead screw 42, thereby clamping or replacing the mold 5. This design also makes the locking blocks at the upper end of the clamping blocks 43 more stable when they are engaged in the positioning groove 44. At the same time, this design makes the clamping blocks 43 more stable when they move in the moving groove 41, thus preventing the mold 5 from shaking when the two sets of clamping blocks 43 are clamped on the outer surface of the mold 5.

[0021] The ultrasonic plastic welding machine 8 is a product that can be purchased directly on the market. Its principle, connection method and control method are existing technologies that are well known to those skilled in the art, so they will not be described in detail here.

[0022] The lead screw 42 and the two sets of clamping blocks 43 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0023] Example 2, as Figure 3 and Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes: the quick-connect structure 9 includes a first connecting pipe 91, a second connecting pipe 92, a movable groove 93, a movable plate 94, a spring 95, a water tank 96, a water pump 97, an output pipe 98, an input pipe 99, a docking interface 910, and a positioning hole 911. The outer surface of one end of the mold 5 is connected to the first connecting pipe 91, and the outer surface of one end of the mold 5 is connected to the second connecting pipe 92. Movable grooves 93 are opened inside the outer surfaces of both ends of the first connecting pipe 91 and the second connecting pipe 92. The movable plate 94 is engaged inside the movable groove 93, and the spring 95 is provided inside the movable groove 93. The outer surface of one end of the movable groove 41 is fixedly connected to the water tank 96, and the water pump 97 is installed inside the water tank 96. The output end of the water pump 97 is connected to the output pipe 98. The upper end of the output pipe 98 is engaged inside the outer surface of one side of the upper end of the output pipe 98, and the outer surface of the other side of the upper end of the water tank 96 is connected to the water tank 96. An input tube 99 is internally connected to an output tube 98. The upper outer surfaces of the input tube 99 and the output tube 98 are respectively provided with interfaces 910. The inner walls of both sides of the interfaces 910 are provided with positioning holes 911. A positioning block is fixedly connected to the outer surface of one side of the lower end of the movable plate 94. The external dimensions of the positioning block are adapted to the internal dimensions of the positioning holes 911. The external dimensions of one end of the first connecting tube 91 and the second connecting tube 92 are adapted to the internal dimensions of the interfaces 910. An insertion rod is fixedly connected to the outer surface of one end of the first connecting tube 91 and the second connecting tube 92. The insertion rod is made of rubber. This design makes the positioning block more stable when inserted into the positioning holes 911, thereby making the movable plate 94 more stable when inserted into the interfaces 910. The good elasticity and sealing of the insertion rod itself can prevent leakage at the connection between the first connecting tube 91 and the second connecting tube 92 and the input tube 99 and the output tube 98.

[0024] The two ends of the spring 95 abut against the surface of the other side of the movable plate 94 and the inner wall surface of the movable groove 93, respectively. A plug is inserted into the inner surface of the upper outer surface of the water tank 96. This design allows the movable plate 94 to move inside the movable groove 93 and then return to its original position under the elasticity of the spring 95. This allows the positioning block to be inserted into the positioning hole 911 to position the first connecting pipe 91 and the input pipe 99 and the second connecting pipe 92 and the output pipe 98. Furthermore, by pulling the plug upwards, water can be added to the inside of the water tank 96.

[0025] Working principle: When the device is in use, the mold 5 is placed on the outer surface of the placement seat 3. At this time, the lead screw 42 can be rotated to make the clamping blocks 43 at both ends of the lead screw 42 move inward synchronously, so that the two sets of clamping blocks 43 fit tightly against the outer surfaces of both sides of the mold 5, and the locking block engages inside the positioning groove 44, thereby completing the positioning of the mold 5. Then, the two sets of movable plates 94 can be pinched together, so that the positioning block at the lower end of the movable plate 94 is stored inside the movable groove 93. At this time, the first connecting pipe 91 and the second connecting pipe 92 can be inserted into the two sets of mating interfaces 910 in sequence. Then, the movable plate 94 can be released, so that the movable plate 94 will automatically release under the elasticity of the spring 95. The system is reset, which allows the positioning block at the lower end of the movable plate 94 to be inserted into the positioning hole 911, and the two sets of insertion rods to be inserted into the output pipe 98 and the input pipe 99 respectively. This completes the connection between the mold 5 and the water tank 96. At the same time, the water pump 97 can be started, which draws the stored water from the water tank 96 and pumps the stored water into the mold 5 through the output pipe 98 and the second connecting pipe 92. After circulating inside the mold 5, the stored water is discharged back into the water tank 96 through the first connecting pipe 91 and the input pipe 99 for reuse. The stored water can also be added by pulling out the plug upwards into the water tank 96. This is the complete working principle of this utility model.

[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
