Description

Technical Field

[0001] The invention relates to the technical field of vehicle lamp production equipment, in particular to a hot melt adhesive cooling device for vehicle lamp manufacturing. Background Art

[0002] Car lights include high and low beam lights, width lights, fog lights, daytime running lights, turn signals, etc. Different lights have different uses, and car lights need hot melt adhesive to connect and fix during the production and assembly process. Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport and store, and the production process is simple, high added value, high bonding strength, fast speed and other advantages are highly favored. Hot melt adhesive has a good fixing and sealing effect when assembling car lights, and has high stability and a long service life.

[0003] Existing headlights are generally bonded and fixed with hot melt adhesive during assembly, and then left to cool naturally. However, the natural cooling efficiency is low, and some headlights have many assembly parts, which require more hot melt adhesive. This can easily cause the headlights to shake during transfer, and then cause the headlight parts to be misaligned and offset before the hot melt adhesive dries. Finally, after drying, it affects the connection strength and sealing between the headlight assembly structures. Therefore, we proposed a hot melt adhesive cooling device for headlight manufacturing. Summary of the invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in the present invention is:

[0006] A hot melt adhesive cooling device for manufacturing vehicle lamps, comprising: a seat mechanism and a cooling mechanism; the seat mechanism comprises a storage plate, a lifting leg mounted on the side of the storage plate and a lifting rod arranged on the driving end of the lifting leg; the cooling mechanism comprises a fixing assembly arranged on the lifting rod, an anti-curing assembly mounted on the fixing assembly and an air cooling assembly arranged on the lifting rod; the fixing assembly comprises a positioning rod inserted on the lifting rod, a cross frame fixed to the top of the positioning rod, an electric telescopic rod hingedly mounted on the middle of the cross frame, a pressure sensor fixed to the driving end of the electric telescopic rod, a pad hingedly fixed to the bottom of the pressure sensor, a limit plate fixed to one end of the electric telescopic rod, a fixing rod sleeved on the driving end of the electric telescopic rod and located below the limit plate, a fixing head fixed to the end of the fixing rod, a positioning frame mounted on the positioning rod and through which the fixing rod passes, a positioning slot opened on the side of the lifting rod, a handle mounted on the cross frame and a control button fixed on the handle.

[0007] In a preferred example, the present invention can be further configured as follows: the anti-curing component includes an electric telescopic rod 2 installed on the fixed rod and a heating lamp fixed to the driving end of the electric telescopic rod 2 and sleeved on the fixed rod.

[0008] In a preferred example, the present invention can be further configured as follows: the air cooling component includes a cooling fan installed on the side of the positioning rod, a duct connected to the cooling fan and fixed in the positioning rod, a slot opened in the middle of the lifting rod for the positioning rod to be plugged in, and an air hole opened on the side of the slot.

[0009] In a preferred example, the present invention can be further configured as follows: a hanging rod is installed on the top of the positioning rod.

[0014] The above technical solution of the present invention has the following beneficial technical effects:

[0015] 1. The present invention can assemble and glue the headlight on the storage plate through the cooling mechanism. After the assembly is completed, the cross frame is placed above the storage plate, and the positioning rod is inserted into the slot. When the cushion block is pressed on the headlight, it will push the fixing rod to deform, so that the end of the fixing rod passes through the positioning slot and presses on the positioning rod. Then, the control button is pressed to complete the locking of the electric telescopic rod. In this way, the headlight is fixed to avoid shaking during the transfer process, which causes the misalignment of the headlight and ensures the molding quality of the headlight.

[0016] 2. The present invention can control the operation of the electric telescopic rod 2 through a control button through the cooling mechanism, so that the heating lamp moves on the fixed rod to adjust the irradiation range and aligns with the hot melt adhesive area to prevent the hot melt adhesive from solidifying. This not only prevents the hot melt adhesive from being offset during the transfer process and then cooled down to cause dislocation, but also allows the hot melt adhesive to flow further into the gap of the headlight connection after being heated, thereby improving the connection strength and sealing of the hot melt adhesive. Finally, after the transfer is completed, the heating lamp is turned off, and the cooling fan can be controlled to blow gas into the slot through the conduit, and then spray it out from the air hole to quickly cool the hot melt adhesive on the inner headlight. The delayed cooling scheme can greatly improve the assembly quality of the headlight and has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0024] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0025] A hot melt adhesive cooling device for manufacturing vehicle lamps provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 to Figure 2 As shown, a hot melt adhesive cooling device for manufacturing a vehicle lamp provided by the present invention comprises: a seat body mechanism 100 and a cooling mechanism 200; the seat body mechanism 100 comprises a storage plate 110, a lifting leg 120 installed on the side of the storage plate 110, and a lifting rod 130 arranged on the driving end of the lifting leg 120, the storage plate 110 can be used to place the vehicle lamp when it is assembled, and it is convenient to transfer the vehicle lamp after it is combined with the cooling mechanism 200, and the lifting leg 120 can drive the lifting and lowering of the lifting rod 130, which is convenient for adjusting when fixing vehicle lamps of different heights and sizes, and is more practical;

[0027] The cooling mechanism 200 includes a fixing assembly arranged on the lifting rod 130, an anti-curing assembly installed on the fixing assembly and an air-cooling assembly arranged on the lifting rod 130, wherein the fixing assembly includes a positioning rod 210 inserted on the lifting rod 130, a cross frame 220 fixed to the top of the positioning rod 210, an electric telescopic rod 230 hingedly installed in the middle of the cross frame 220, a pressure sensor 240 fixed to the driving end of the electric telescopic rod 230, a cushion block 250 hingedly fixed to the bottom of the pressure sensor 240, a limit plate 260 fixed to the end of the electric telescopic rod 230, a fixing rod 270 sleeved on the driving end of the electric telescopic rod 230 and located below the limit plate 260, a fixing head 280 fixed to the end of the fixing rod 270, and an installation The positioning frame 290 installed on the positioning rod 210 and for the fixing rod 270 to pass through, the positioning slot 131 opened on the side of the lifting rod 130, the handle 221 installed on the cross frame 220 and the control button 222 fixed on the handle 221 can be assembled and glued on the car light on the storage plate 110 through the cooling mechanism 200. After the assembly is completed, the cross frame 220 is placed above the storage plate 110, and the positioning rod 210 is inserted into the slot 350. When the cushion block 250 is pressed on the car light, it will push the fixing rod 270 to move, so that the end of the fixing rod 270 passes through the positioning slot 131 and presses on the positioning rod 210, and then presses the control button 222 to complete the locking of the electric telescopic rod 230. In this way, the car light is fixed to avoid shaking during the transfer process, which causes the misalignment of the car light.

[0028] Specifically, the anti-curing component includes an electric telescopic rod 210 installed on the fixed rod 270 and a heating lamp 320 fixed to the driving end of the electric telescopic rod 210 and sleeved on the fixed rod 270. The electric telescopic rod 210 can drive the heating lamp 320 to adjust the irradiation position, and the heating lamp 320 is a linear focusing infrared heater, which can prevent the glue from cooling during irradiation. With the setting of the fixed rod 270, the heating lamp 320 can more conveniently irradiate the hot melt glue position on the car light, and has high practicality.

[0029] Furthermore, the air cooling assembly includes a cooling fan 330 installed on the side of the positioning rod 210, a conduit 340 connected to the cooling fan 330 and fixed in the positioning rod 210, a slot 350 opened in the middle of the lifting rod 130 for the positioning rod 210 to be plugged in, and an air hole 360 ​​opened on the side of the slot 350. The operation of the electric telescopic rod 310 can be controlled by the control button 222, so that the heating lamp 320 moves on the fixing rod 270 to adjust the irradiation range and aligns with the hot melt adhesive area to prevent the hot melt adhesive from solidifying. This not only prevents the hot melt adhesive from being offset and then cooled during the transfer process, causing dislocation, but also allows the hot melt adhesive to flow further into the gap of the headlight connection after being heated, thereby improving the connection strength and sealing of the hot melt adhesive. Finally, after the transfer is completed, the heating lamp 320 is turned off, and the cooling fan 330 can be controlled to blow the gas into the slot 350 through the conduit 340, and then spray it out from the air hole 360 ​​to quickly cool the hot melt adhesive on the inner headlight. This solution uses delayed cooling to greatly improve the assembly quality of the headlight and is highly practical.

[0030] Specifically, a lifting rod 211 is installed on the top of the positioning rod 210, and the device can be connected to the lifting equipment, so that the device can be automatically transferred. Of course, the device and the car light can also be transferred manually by holding the handle 221, which is highly practical.

[0031] Furthermore, a protective pad 111 is fixed on the storage plate 110 , and a positioning groove 112 is provided on the protective pad 111 . The positioning groove 112 is a structure of multiple evenly distributed grooves, which can provide a positioning effect after the bottom edge of the headlight falls, thereby preventing the headlight from shifting on the storage plate 110 .

[0032] On the other hand, a sealing ring 212 is provided at the bottom of the positioning rod 210, which can play a sealing role when the positioning rod 210 is inserted into the lifting rod 130, preventing the air-cooled gas from overflowing upward, ensuring the air-cooling intensity, which is more reasonable.

[0033] Furthermore, the positioning rod 210 is provided with a slot 341 located on the side of the positioning groove 131, and the fixing head 280 is fixed with a block 342 corresponding to the slot 341, which can improve the stability after the fixing head 280 is pushed onto the positioning rod 210, prevent the fixing head 280 from detaching, and thereby ensure the stability of the fixation of the car light.

[0034] It should be noted that the fixing rod 270 is a tapered strip structure. When the end of the electric telescopic rod 230 is extended, the limiting plate 260 can be used to press down the fixing rod 270, so that the outer end of the fixing rod 270 moves outward and then passes through the positioning groove 131 to be fixed on the positioning rod 210, which is more reasonable.

[0035] The working principle and use process of the present invention are as follows: first, the storage plate 110 is placed on the lamp assembly station, and the lamp is assembled and glued on the storage plate 110. When the hot melt glue is applied, the cross frame 220 is placed on the storage plate 110, and the positioning rod 210 is inserted into the slot 350 and pressed down continuously. When the pad 250 is pressed on the lamp, it pushes the fixing rod 270 to deform, so that the end of the fixing rod 270 passes through the positioning slot 131 and presses on the positioning rod 210, and then The control button 222 is pressed to lock the electric telescopic rod 1 230, and then the control button 222 is used to control the operation of the electric telescopic rod 2 310, so that the heating lamp 320 moves on the fixing rod 270 to adjust the irradiation range, and is aimed at the hot melt adhesive area to prevent the hot melt adhesive from solidifying. After the transfer is completed, the heating lamp 320 is turned off, and the cooling fan 330 blows the gas into the slot 350 through the conduit 340, and then sprays it out from the air hole 360 ​​to quickly cool the hot melt adhesive on the inner headlight.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
