Description

Technical Field

[0001] The invention relates to the technical field of assembly and processing of automobile lamps, in particular to a device used in the gluing and pressing process of automobile lamps. Background Art

[0002] Cars are the most common means of transportation at present. Car lights are an important part of cars, which provide necessary lighting for driving. Generally, car lights are composed of lamp holders and masks. After installing electronic components such as bulbs on the lamp holders, the mask is fixed on the lamp holders. During the process, the airtightness inside the lamps needs to be ensured to prevent affecting the lighting effect of the lamps. Generally, there is a glue filling groove on the edge of the lamp holder and a clamping edge on the mask. During the production process, glue is applied in the glue filling groove of the lamp holder, and then the clamping edge of the mask is pressed on the lamp holder, so that the lamp holder and the mask are fixed together, and at the same time, it has a sealing and waterproof effect. This is a very important link in the assembly process of car lights. In addition, during the process of injection molding of the lamp holder, a release agent will be sprayed in the mold to facilitate the demolding of the lamp holder after molding. The release agent will affect the adhesion of the melt. Therefore, before applying glue to the glue filling groove of the lamp holder, the surface of the glue filling groove (material) of the lamp holder will be flame treated with ion fire, so that the tension of the material surface can be increased at the same time to ensure better adhesion with the melt. At present, the assembly process of car lights requires a lot of manual labor, such as manual positioning, manual gluing, and transfer between different workstations, with a low degree of automation. In addition, the car lights are composed of two parts, left and right, and they are processed separately or one of them is processed alone, resulting in low processing efficiency and high cost. Summary of the invention

[0003] The purpose of the present invention is to provide a device for the gluing and pressing process of automobile lamps, which has a simple structure, is flexible to use, has a high degree of automation, and can reasonably arrange the production rhythm according to the production tasks, thereby improving the production efficiency of the assembly of automobile lamps.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0006] Preferably, a position sensor is provided on the lower machine base, and a positioning point is provided at the bottom of the slide, and the slide stops rotating after the position sensor detects the positioning point.

[0007] Preferably, a supporting structure is also included, which is arranged on the lower machine base and located at the bottom of the slide, and the supporting structure includes a wedge-shaped slider and a support block. One end of the wedge-shaped slider is connected to the second cylinder, and the second cylinder pushes the wedge-shaped slider to slide into the bottom of the support block to lift the support block and form a supporting force on the slide, and the second cylinder drives the wedge-shaped slider to retract and cause the support block to drop away from the slide.

[0008] Preferably, the support block is fixed on the lower machine base through a base, the top of the base is a box body, the support block is located in the box body and can protrude from the top of the box body, and the wedge-shaped slider slides from one side of the box body into the bottom of the support block.

[0009] Preferably, a lower mounting seat is fixed on the mounting groove, an upper mounting seat is provided on the upper machine seat, lamp housing tooling is fixed on the upper mounting seat and the lower mounting seat, the lower mounting seat and the upper mounting seat both include a base plate and a plurality of support rods, one end of the support rod is fixed on the base plate and the other end is fixed to the lamp housing tooling and follows the shape of the lamp housing tooling.

[0010] Preferably, the upper mounting seat is provided with a plurality of suction cups; the lower mounting seat is provided with an ejection mechanism and a detection device; the lower mounting seat is provided with a first positioning column, the end of which is provided with a guide column, and the upper mounting seat is provided with a second positioning column, the end of which is provided with a guide sleeve.

[0011] Preferably, baffles are provided between the three groups of mounting grooves; each group of mounting grooves comprises two U-shaped clamping plates, the opening positions of the two U-shaped clamping plates are arranged relatively, and the U-shaped clamping plates are fixedly connected to the slide.

[0012] Preferably, the upper machine base is also provided with a first cylinder, a mounting plate is fixedly connected to the lower side of the first cylinder, at least four hooks are provided on the mounting plate, and the hooks are divided into two groups for installing and fixing the upper mounting base; a positioning hole is provided on the edge side of the mounting plate, and a third positioning column is provided between the upper machine base and the lower machine base, and the third positioning column is passed through the positioning hole.

[0013] Preferably, the slide is also provided with a positioning sensor for monitoring whether the lower mounting seat is fixed in place; an electrical control unit and an air pump are arranged in the lower machine base for providing electricity, a control system and a power source for the cylinder.

[0014] Preferably, another set of devices for the gluing and pressing process of automobile lamps is symmetrically arranged on one side of the lower machine base, and the gluing robot and the flame spraying robot are arranged between the two sets of devices for the gluing and pressing process of automobile lamps.

[0015] In the above technical scheme, a slide is provided on the lower machine base, and three groups of mounting grooves are provided on the slide. The mounting grooves are used to fix and install the lower mounting base. The mounting grooves are U-shaped clamping plates corresponding to the openings. The bottom plate of the lower mounting base can be inserted into the clamping plate from one side to fix the tooling. The fixing method of the U-shaped clamping plate can easily realize the replacement of the lamp housing tooling, so that it can be used for the processing and production of lamp housings of different shapes, thereby improving the utilization efficiency of the equipment. The overall structure is simple and easy to operate. The three groups of mounting grooves correspond to the upper machine base, the gluing manipulator and the flame spraying manipulator to form the firing, gluing and pressing stations, and the three stations are integrated together to reduce the working area. At the same time, the pressing station can realize the operation of taking and loading the parts by one person, saving labor. At the same time, when the slide rotates on the lower machine base, it drives the stations of the three groups of mounting grooves to rotate, so that the three stations can be transferred and operated separately between the firing, gluing and pressing processes, which can improve the production work efficiency. A support structure is provided at the bottom of the slide, and the support structure is provided with a wedge-shaped slider and a support block. When the upper machine base moves downward, the wedge-shaped slider is inserted into the bottom of the support block so that the support block is raised and fits with the lower bottom surface of the slide, thereby playing the role of supporting the slide, and preventing the slide from tilting and shaking due to the huge pressure during the pressing of the upper lamp shell on the lower lamp shell, thereby affecting the processing accuracy. After the pressing is completed, the upper machine base begins to move upward, and at the same time, the wedge-shaped slider slides out from the bottom of the support block, and the support block descends and moves away from the lower bottom surface of the slide, which does not affect the sliding rotation of the slide. A position sensor is also provided on the upper machine base, and the slide is provided with a positioning point. When the slide rotates to the correct position, the positioning point corresponds to the position sensor. At this time, the position sensor receives the signal of the positioning point, and the slide stops rotating, which effectively ensures that the slide drives the three stations to rotate and can always stop at the correct position, preventing position deviation during the operation.

[0016] Another set of processing equipment is symmetrically arranged on the other side of the lower machine base, and the gluing robot and the flame spraying robot are located between the two sets of processing equipment so that the two sets of equipment can share the gluing robot and the flame spraying robot, further improving the use efficiency of the gluing robot and the flame spraying robot, saving investment costs, and indirectly improving work efficiency.

DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings:

[0033] like Figures 1 to 14 The invention shows a device for gluing and pressing process of automobile lamps, comprising a lower machine base 1, on which a rotatable slide 3 is provided, and three groups of mounting grooves 4 are evenly arranged circumferentially on the slide 3 to form three workstations, and baffles 31 are provided between the three groups of mounting grooves to separate and prevent mutual interference between the workstations, and the mounting grooves 4 are used to install and fix the lower lamp housing, and each group of mounting grooves 4 comprises two U-shaped clamping plates 41, and the opening positions of the two U-shaped clamping plates 41 are relatively arranged, and the U-shaped clamping plates 41 are fixedly connected to the slide, and the bottom plate 101 of the lower mounting seat 10 can be inserted from one side of the U-shaped clamping plate 41, that is, fixedly installed on the slide, the process is simple and convenient, and the fixing method is reliable and stable, and the lower lamp housing is fixed on the lower mounting seat 10. An upper machine base 2 is provided at the top of one side of the lower machine base 1. The upper machine base 2 is provided with a first cylinder 21. A mounting plate 22 is fixedly connected to the lower side of the first cylinder 21. The mounting plate 22 is provided with at least four hooks 23. The hooks 23 are divided into two groups and are hooked on the bottom plate 101 of the upper mounting base 100 to fix the upper mounting base 100. The upper lamp housing is fixed on the upper mounting base. Gluing manipulators 5 and flame spraying manipulators 6 are provided at both ends beside the lower machine base 1. The three groups of mounting grooves 4 correspond to the positions of the upper machine base 2, the glue coating manipulators 5 and the flame spraying manipulators 6, respectively, to form a pressing station, a glue coating station and a firing station.

[0034] The lower machine base 1 is also provided with a support structure 9, which includes a wedge-shaped slider 91 and a support block 92. One end of the wedge-shaped slider 91 is connected to the second cylinder 94. The second cylinder 94 pushes the wedge-shaped slider 91 to slide into the bottom of the support block 92 so that the support block 92 lifts the lower bottom surface of the slide 1 and forms a support force on the slide 1 to prevent the slide 3 from tilting and shaking during the pressing of the lamp housing, thereby affecting the processing of other stations. After the pressing is completed, the second cylinder 95 drives the wedge-shaped slider 91 to retract so that the support block 92 drops away from the slide 3, so that the slide 3 can slide smoothly. The support block 92 is fixed to the lower machine base 1 through a base 93. The top of the base 93 is a box body 94. The support block 92 is located in the box body 94 and can protrude from the top of the box body 94. The support block 92 can move in the box body 94 and will not fall out of the box body 94. The wedge-shaped slider 91 can slide from one side of the box body 94 into the bottom of the support block 92. A position sensor 8 is also provided on the lower base 1, and a positioning point 81 is provided at the bottom of the slide 3. After the position sensor 8 detects the positioning point 81, the slide 3 stops rotating, which is used for positioning the three stations during the rotation process. A positioning sensor 32 is also provided on the slide 3. The positioning sensor 32 is used to monitor whether the lower mounting base 10 is installed in place and the detector is shaken and shifted, which can further ensure the processing accuracy of the lamp housing and prevent unqualified products.

[0035] In a preferred case, a lower mounting seat 10 is fixed on the mounting groove 4, an upper mounting seat 100 is provided on the upper machine base 2, and an upper lamp housing tooling 34 and a lower lamp housing tooling 33 are fixed on the upper mounting seat 100 and the lower mounting seat 10 respectively. Both the lower mounting seat 10 and the upper mounting seat 100 include a bottom plate 101 and a plurality of support rods 102, one end of the support rods 102 is fixed on the bottom plate 101 and the other end is fixed on the upper lamp housing tooling 34 and the lower lamp housing tooling 3 and matches the shape of the upper lamp housing tooling 34 and the lower lamp housing tooling 3. A plurality of suction cups 110 are provided on the upper mounting seat 100. In this embodiment, four suction cups are preferably provided, and the suction cups 110 adsorb and fix the upper lamp housing on the upper lamp housing tooling 34. Several ejection mechanisms 103 and detection devices 106 are provided on the lower mounting seat 10. The ejection mechanism 103 is connected to the air pump and can perform telescopic movement on the bottom side of the lower lamp shell. After the lamp is pressed together, the ejection mechanism 103 extends upward to push the roof out of the lower mounting seat 10, making it convenient for personnel to quickly remove the lamp. The detection device 106 can be an electromagnetic induction sensor to detect whether a lamp shell is placed on the lower lamp shell tooling 33 to prevent misoperation of the equipment. A clamping mechanism 107 is also provided on the lower mounting seat 10. After the lower lamp shell is placed on the lower lamp shell tooling 33, the clamping mechanism 107 clamps the lower lamp shell on the lower lamp shell tooling 33. Furthermore, a first positioning column 104 is provided on the lower mounting seat 10, and a guide column 105 is provided at the end of the first positioning column 104. A second positioning column 111 is provided on the upper mounting seat 100, and a guide sleeve 112 is provided at the end of the second positioning column 111. When the upper mounting seat 100 moves downward and drives the upper lamp housing to be pressed on the lower lamp housing, the guide column 105 first enters the guide sleeve 112 for pre-positioning, further ensuring the accuracy of processing. Furthermore, a positioning hole 24 is provided on the edge side of the mounting plate 22, and a third positioning column 11 is provided between the upper machine base 2 and the lower machine base 1. The third positioning column 11 is penetrated in the positioning hole 24 to position the mounting plate 22.

[0036] In a preferred case, the lower machine base 1 also includes an electrical control unit and an air pump, which are used to provide electricity to the device, provide a power source for the cylinder, and set the control unit. Furthermore, the slide 3 is connected to the electrical control unit of the lower machine base through a conductive slip ring. The use of a conductive slip ring can avoid the problem of winding wires during the rotation of the slide. In another preferred case, another group of devices 7 for the gluing and pressing process of automobile headlights are symmetrically arranged on the other side of the lower machine base 1. The gluing manipulator 5 and the flame spraying manipulator 6 are located between the two groups of devices for the gluing and pressing process of automobile headlights. The two groups of devices can share the gluing manipulator 5 and the flame spraying manipulator 6, improve the utilization rate of the gluing manipulator 5 and the flame spraying manipulator 6, and indirectly save manufacturing costs. At the same time, the production rhythm can be reasonably arranged according to the production task. The three stations of the two devices can process the left and right headlights at the same time, maximizing the use efficiency of the equipment and thus improving the production efficiency. Or when the output is sufficient, only one or two stations of a device are used for production, so that the equipment has a certain buffer interval time to avoid excessive use, causing fatigue of parts and affecting the service life.

[0037] When in use, fix the lower lamp shell tooling of the headlight to be processed on the lower mounting seat and insert the bottom plate into the U-shaped clamping plate to fix it on the slide, fix the upper lamp shell tooling on the upper mounting seat and clip it into the hook. The three sets of mounting slots of the slide correspond to the upper machine base, the gluing robot and the flame spraying robot respectively. Put the lower lamp shell into the lower lamp shell tooling, and the upper lamp shell into the upper lamp shell tooling, start the power supply, and the motor drives the slide to rotate. When the position sensor senses the positioning point, the lamp shell is transferred to the position of the flame spraying robot and the other station is transferred to the position corresponding to the upper machine base. At this time, the slide stops rotating, and the flame spraying robot performs fire processing on the lower lamp shell. The operator performs the second placement operation at the position corresponding to the upper machine base. After this process is completed, the detection device detects that the lower lamp shell is in place and the slide continues to rotate. After that, the lamp shell that has been fired is transferred to the gluing robot position. At the same time, the second placement position is transferred to the manual position of the flame spraying robot and the third station corresponds to the position of the upper machine base. This When the position sensor senses the positioning point, the slide stops rotating, the glue coating robot glues the lower lamp shell after the fire, and the flame spraying robot fires the second placement of the parts and the staff places the parts for the third time at the third station. After the detection device detects that the lower lamp shell is in place, the slide continues to rotate and stops rotating at the set position. At this time, the upper machine seat moves downward under the push of the first cylinder, and at the same time, the second cylinder pushes the wedge-shaped slider to slide into the bottom of the support block, so that the support block contacts the bottom of the slide. After that, the first cylinder continues to press the mounting plate, i.e., the upper lamp shell tooling, so that the upper lamp shell is pressed into the glue groove of the lower lamp shell and sealed together to complete the processing of the car lamp. The operator removes the processed car lamp ejected by the ejection mechanism, and continues to install the upper and lower lamp shells to be processed, so that the slide continues to rotate, realizing the simultaneous and step-by-step processing of the glue coating robot, the flame spraying robot and the upper machine seat, shortening the processing time and improving work efficiency.

[0038] When two sets of devices for the gluing and pressing process of automobile headlights are used at the same time, while one device is unloading or loading parts, the gluing robot and the flame spraying robot perform gluing or flame spraying processes on the workstation of the other device, thereby realizing the simultaneous processing of the left and right headlights.

[0039] This embodiment is only an illustration of the concept and implementation of the present invention, and does not limit it. Under the concept of the present invention, technical solutions that have not been substantially changed are still within the scope of protection.
