A workbench is fixedly connected to the bottom of the inner side of the machining base. A lamp shell body is arranged on the top of the workbench. According to the utility model, through the use of the flexible clamping assembly, the inner side wall of the lamp housing main body is clamped when the film covering is carried out on the lamp housing main body with different shapes and specifications, and meanwhile, in the clamping process, when a group of half-thread blocks reach the edge of the lamp housing main body, the half-thread blocks do not move; and the clamping of the other group of half-thread blocks on a farther area is not influenced.

Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology and relates to an automotive lamp housing processing and coating machine. Background Technology

[0002] Automotive headlight housings are the core components of vehicle lighting systems. Currently, they are mainly made of polycarbonate, which has strong impact resistance. They are also generally coated with a hard, transparent coating to improve their scratch resistance.

[0003] When using the above technology, the following technical problems were found in the prior art: When applying a protective film to the surface of the car headlight housing, it is necessary to first apply the protective film to the surface of the headlight housing, and then apply the film with a hot air gun. However, the headlight housing is relatively light, and if it is affected by airflow during the film application, it may cause the headlight housing to shift. Since the headlight housings have different shapes, ordinary clamps are not effective in holding them and cannot accurately position them at equal distances, which affects the accuracy of the film application. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when applying a protective film to the surface of a car headlight housing, it is necessary to first attach the protective film to the surface of the headlight housing and then apply the film with a hot air gun. However, the headlight housing is relatively light, and if it is affected by airflow during the film application, it may shift. Since the headlight housings have different shapes, ordinary clamps are not effective and cannot accurately position the equidistant positions, thus affecting the accuracy of the film application.

[0005] The present invention discloses an automotive lamp housing processing and laminating machine, comprising a processing base; a worktable fixedly connected to the bottom inner side of the processing base; a lamp housing body disposed on the top of the worktable; an electric slide rail fixedly connected to the top inner side of the processing base; a sliding block slidably connected to the outside of the electric slide rail; a heating roller fixedly connected to the bottom of the sliding block; a film rolling roller installed on one side of the heating roller; and a laminating module installed on the side of the heating roller away from the film rolling roller.

[0006] The flexible clamping assembly is located at the bottom inner side of the processing base; the flexible clamping assembly includes a compression limiting mechanism and a fixing mechanism. The combined use of the compression limiting mechanism and the fixing mechanism can provide a good clamping effect for various irregularly shaped lamp housings.

[0007] The flexible clamping assembly includes a clamping groove; the clamping groove is fixedly connected to the bottom inner side of the processing base; a servo motor is fixedly connected to one side of the outer side of the clamping groove; a bidirectional lead screw is fixedly connected to the output end of the servo motor; the bidirectional lead screw is rotatably connected inside the clamping groove; limit grooves are formed on both sides of the outer side of the clamping groove; a semi-threaded block is threadedly connected to the outer side of the bidirectional lead screw; the semi-threaded block slides inside the clamping groove; a spring rod is fixedly connected to the top of the semi-threaded block; a clamping block is fixedly connected to the end of the spring rod; the clamping block slides inside the limit groove.

[0008] The compression limiting mechanism includes a toothed rotating threaded cylinder; the toothed rotating threaded cylinder is rotatably connected inside the clamping block; a threaded rod is threadedly connected inside the toothed rotating threaded cylinder; one end of the threaded rod is rotatably connected to a semi-threaded block; two sets of limiting sliding grooves are opened inside the clamping block near the toothed rotating threaded cylinder; a sliding rack is slidably connected inside the limiting sliding groove; the sliding rack meshes with the toothed rotating threaded cylinder; a rubber flexible plate is fixedly connected to one outer end of the sliding rack; a buffer spring is fixedly connected to one side of the rubber flexible plate; one end of the buffer spring is connected to the clamping block.

[0009] The fixing mechanism includes a fixing plate; the fixing plate is located on the outer side of the clamping block; a spring hinge shaft is hinged to the middle of the inner side of the fixing plate; a drive button is installed on the outer side of the semi-threaded block near the spring hinge shaft; telescopic rods are fixed to both sides inside the semi-threaded block; the telescopic rods are driven by the drive button.

[0010] Limiting blocks are fixed to both sides of the outer side of the clamping block; the limiting blocks slide inside the limiting groove; two sets of roller grooves are opened at the outer end of the clamping block; a rolling shaft is rotatably connected inside the roller groove.

[0011] A friction plate is fixedly connected to the telescopic end of the telescopic rod.

[0012] The rubber flexible sheet is made of silicone and polyethylene composite material.

[0013] Compared with existing technologies, the advantages of this invention are as follows: By using a flexible clamping component, the inner wall of lamp housings of different shapes and specifications can be clamped during film coating. Simultaneously, during clamping, once one set of semi-threaded blocks reaches the edge of the lamp housing, it will not move, and this does not affect the other set of semi-threaded blocks clamping areas further away. Furthermore, the combined use of a buffer spring and a threaded rod achieves better clamping performance while reducing the risk of lamp housing breakage due to excessive clamping force. This invention allows for more precise positioning during lamp housing clamping, while also reducing the possibility of lamp housing breakage due to excessive clamping force.

[0014] When the telescopic rod presses against the inner wall of the clamping groove, the friction plate is located between the contact point between the telescopic rod and the clamping groove, increasing the friction between the telescopic rod and the clamping groove, and further improving the stability of the semi-threaded block inside the clamping groove.

[0026] Example 1

[0027] like Figures 1-5 As shown, an automotive lamp housing processing and laminating machine includes a processing base 1; a worktable 101 is fixedly connected to the bottom inner side of the processing base 1; a lamp housing body 102 is disposed on the top of the worktable 101; an electric slide rail 103 is fixedly connected to the top inner side of the processing base 1; a sliding block 104 is slidably connected to the outside of the electric slide rail 103; a heating roller 106 is fixedly connected to the bottom of the sliding block 104; a film rolling roller 105 is installed on one side of the heating roller 106; and a film application module 107 is installed on the side of the heating roller 106 away from the film rolling roller 105.

[0028] A flexible clamping assembly is located at the bottom inner side of the processing base 1. The flexible clamping assembly includes a compression limiting mechanism and a fixing mechanism. The combined use of the compression limiting mechanism and the fixing mechanism provides excellent clamping effect for various irregularly shaped lamp housings. The flexible clamping assembly includes a clamping groove 2. The clamping groove 2 is fixedly connected to the bottom inner side of the processing base 1. A servo motor 201 is fixedly connected to one side of the clamping groove 2. A bidirectional lead screw 202 is fixedly connected to the output end of the servo motor 201. The bidirectional lead screw 202 is rotatably connected inside the clamping groove 2. Limiting grooves 203 are formed on both sides of the outer side of the clamping groove 2. A semi-threaded block 204 is threadedly connected to the outer side of the bidirectional lead screw 202. The semi-threaded block 204 slides inside the clamping groove 2. A spring rod 205 is fixedly connected to the top of the semi-threaded block 204. A clamping block 206 is fixedly connected to the end of the spring rod 205. The clamping block 206 slides inside the limiting groove 203. The compression limiting mechanism includes a toothed rotating threaded cylinder 3; the toothed rotating threaded cylinder 3 is rotatably connected inside the clamping block 206; a threaded rod 301 is threadedly connected inside the toothed rotating threaded cylinder 3; one end of the threaded rod 301 is fixedly connected to a semi-threaded block 204; two sets of limiting sliding grooves 302 are opened inside the clamping block 206 near the toothed rotating threaded cylinder 3; a sliding rack 303 is slidably connected inside the limiting sliding groove 302; the sliding rack 303 meshes with the toothed rotating threaded cylinder 3; a rubber soft plate 304 is fixedly connected to one end of the outer side of the sliding rack 303; a buffer spring 305 is fixedly connected to one side of the outer side of the rubber soft plate 304; one end of the buffer spring 305 is connected to the clamping block 206. The fixing mechanism includes a fixing plate 4; the fixing plate 4 is located on the outer side of the clamping block 206; a spring hinge shaft 401 is hinged to the middle of the inner side of the fixing plate 4; a drive button 402 is installed on the outer side of the semi-threaded block 204 near the spring hinge shaft 401; telescopic rods 403 are fixedly connected to both sides inside the semi-threaded block 204; the telescopic rods 403 are driven by the drive button 402; limit blocks 5 are fixedly connected to both sides outside the clamping block 206; the limit blocks 5 slide inside the limit groove 203; two sets of roller grooves 501 are opened at the outer end of the clamping block 206; a rolling shaft 502 is rotatably connected inside the roller groove 501.

[0029] During operation, the lamp housing body 102 is first placed in the center of the worktable 101, allowing the film application module 107 to position it. The protective film is then pulled out from the outside of the film roll 105, passing through the bottom of the heating roller 106 to connect with the film application module 107. When film application is required on the lamp housing body 102, the sliding block 104 moves outside the electric slide rail 103, and the heating roller 106 moves up and down to position the lamp housing body 102. At this point, the film application module 107 is not activated. The heating roller 106 is then brought close to the top of the lamp housing body 102, with the protective film separating them, reducing the possibility of damage to the surface of the lamp housing body 102 by the heating roller 106. When the heating roller 106 presses and positions the surface of the lamp housing body 102, the drive servo motor 201 drives the bidirectional lead screw 202 to rotate inside the clamping groove 2. At this time, the semi-threaded blocks 204 move away from or closer to each other inside the clamping groove 2 to internally clamp the irregularly shaped lamp housing body 102. When one set of rubber flexible plates 304 contacts the inner wall of the lamp housing body 102, the lamp housing body 102 is subjected to the downward pressure provided by the heating roller 106 and remains stationary. At this time, the rubber flexible plates 304 are compressed, which drives the buffer spring 305 to begin to contract, causing the sliding rack 303 to slide into the limiting sliding groove 302 inside the clamping block 206. While the sliding rack 303 is sliding, it continuously meshes with the toothed rotating threaded cylinder 3, causing the toothed rotating threaded cylinder 3 to begin to rotate, driving the threaded rod 301 to rotate inside the toothed rotating threaded cylinder 3, and at the same time providing an upward force to the semi-threaded blocks 204, at which time the spring rod 205 begins to contract. Due to the inherent characteristics of the semi-threaded block 204, when subjected to external force, it can be pulled upwards while engaged with the double-acting screw 202, thereby disengaging the semi-threaded block 204 from the double-acting screw 202, preventing the double-acting screw 202 from driving the spring rod 205 to continue moving. When the semi-threaded block 204 slides, the limiting block 5 on the outer side of the clamping block 206 cooperates with the limiting groove 203 to fix the height of the clamping block 206. When the clamping block 206 slides inside the limiting groove 203, the contact surface between the clamping block 206 and the limiting groove 203 is the rolling shaft 502 inside the roller groove 501. During the sliding process of the clamping block 206, the rolling shaft 502 also continuously rolls, further reducing the friction between the clamping block 206 and the limiting groove 203, reducing wear caused by long-term sliding, and increasing its service life.

[0030] When the semi-threaded block 204 is pulled upward by the threaded rod 301 and disengages from the bidirectional lead screw 202, the drive button 402 comes into contact with the fixing plate 4. At this time, because the end of the fixing plate 4 is rounded, the rounded corners contact the drive button 402, converting the longitudinal force into a lateral force, thus pressing the drive button 402 with the fixing plate 4. This drives the telescopic rod 403 to extend, squeezing the inner wall of the clamping groove 2, thereby fixing the semi-threaded block 204 inside the clamping groove 2. At the same time, the semi-threaded block 204 and the clamping block 206 are connected to each other by the spring rod 205. The spring rod 205 can only adjust the height and cannot cause the semi-threaded block 204 and the clamping block 206 to shift. At this time, the fixing of the semi-threaded block 204 and the clamping block 206 is completed. One side of the lamp housing body 102 is clamped, while the movement of the other set of semi-threaded blocks 204 is not affected, so that the two sets of semi-threaded blocks 204 can clamp the inner walls of different shapes and models.

[0031] After the lamp housing body 102 is clamped, the film application module 107 pulls the protective film on the surface of the film roll 105 through the bottom of the heating roller 106 and into contact with the heating roller 106. At this time, the heating roller 106 starts to heat up and softens the protective film so that the film application module 107 can apply the protective film to the surface of the lamp housing body 102.

[0032] By using flexible clamping components, the inner wall of the lamp housing body 102 of different shapes and specifications can be clamped during film coating. Simultaneously, during clamping, once one set of semi-threaded blocks 204 reaches the edge of the lamp housing body 102, it will not move, and this does not affect the other set of semi-threaded blocks 204 clamping areas further away. Furthermore, the cooperation between the buffer spring 305 and the threaded rod 301 achieves a better clamping effect while reducing the risk of lamp housing breakage due to excessive clamping force. This device allows for more precise positioning during the clamping of the lamp housing body 102, while also reducing the possibility of breakage due to excessive clamping force.

[0033] Example 2

[0034] like Figures 4-5 As shown, the telescopic rod 403 has a friction plate 6 fixedly connected to its telescopic end. The rubber soft plate 304 is made of silicone and polyethylene composite material. The polyethylene material contacts the buffer spring 305, providing good support while being lightweight. A layer of silicone is laminated on the outside of the polyethylene plate. The silicone material is relatively soft and deforms when it comes into contact with the inner wall of the lamp housing body 102, filling some grooves inside the lamp housing body 102, increasing the contact area with the inner wall of the lamp housing body 102, and increasing the support stability.

[0035] During operation, when the telescopic rod 403 presses against the inner wall of the clamping groove 2, the friction plate 6 is located between the contact point of the telescopic rod 403 and the clamping groove 2, increasing the friction between the telescopic rod 403 and the clamping groove 2, and further improving the stability of the semi-threaded block 204 inside the clamping groove 2.
