Description

Technical Field

[0001] This invention relates to the field of automotive body adhesive technology, specifically to a gantry-type automatic multi-point adhesive application device for automotive door outer panels. Background Technology

[0002] Currently, in the automotive door panel production line, there are two main methods for applying adhesive during the manufacturing process of the outer door panel. The first method involves two employees working together to apply adhesive one point at a time using a manual glue gun. This method requires multiple employees, involves a large amount of machinery, and is labor-intensive. The second method involves employees using a balancer-mounted multi-point adhesive applicator. However, this type of applicator is bulky, poses a risk of falling, and has many application points, making it easy to miss some points.

[0003] In response to the aforementioned situation, Chinese utility model patent application number 201921401597.5 discloses an automatic multi-point glue application device. This device can be designed and the glue application pipeline can be arranged in a graded and segmented manner according to the shape and number of glue application points of door parts for different car models. It not only features adjustable glue application amount, high glue application efficiency, accurate glue application position, and good glue application quality, but also achieves automatic glue application and has reliable safety functions, saving operation time and reducing one job position. Previously, one person applied the shock-absorbing glue to the inner panel while another applied the edge glue to the outer panel; using this automatic glue application tool can reduce one operator and save project costs.

[0004] The existing related technologies have the following technical defects: In the above-mentioned automatic multi-point glue application device, the entire device is supported by the lifting top plate, the device position is relatively fixed and not flexible enough, and the current glue application pipe is usually directly welded to the glue storage box, which makes it inconvenient to maintain and replace when a component fails.

[0005] Therefore, the inventors proposed an automatic multi-point gluing device for car door outer panels using a gantry frame. Utility Model Content

[0006] One of the purposes of this utility model is to provide a gantry-type automatic multi-point glue application device for car door outer panels, so as to solve the problem that the existing glue application device is not flexible enough and the glue application tube is usually directly welded to the glue storage box, which makes it inconvenient to maintain and replace when a component fails.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automatic multi-point gluing device for a car door outer panel gantry frame includes a door support frame and a gluing mechanism and a lifting mechanism mounted on the gantry support frame. The lifting mechanism is used to drive the gluing mechanism to move vertically up and down. The gluing mechanism includes a gluing frame, a dispensing disc, and a gluing tube. The dispensing disc is mounted on the gluing frame. A first connector is provided at the gluing outlet of the dispensing disc. A second connector is provided at one end of the gluing tube. The first connector and the second connector can be engaged or disengaged. When the first connector and the second connector are engaged, the dispensing disc and the gluing tube are connected.

[0009] Furthermore, the first connector includes a first connecting shell, in which a hollow first chamber is formed, and an annular snap-fit ​​groove is provided on the first connecting shell.

[0010] Furthermore, the second connector includes a second connecting shell, a snap-fit ​​member, and a toggle member. A hollow second chamber is formed inside the second connecting shell. The toggle member is slidably disposed on the second connecting shell. When the first connector and the second connector are engaged, the toggle member tends to drive the snap-fit ​​member into the annular snap-fit ​​groove.

[0011] Furthermore, along the radial direction of the second connecting shell, a plurality of mounting grooves are provided on the second connecting shell;

[0012] The snap-fit ​​component includes a plurality of snap-fit ​​balls, each of which is installed in one of the mounting slots.

[0013] Furthermore, a connecting protrusion is formed on the outer periphery of the second connecting shell;

[0014] The actuating element includes a first elastic element and an actuating ring. A pressing portion is formed on the inner side of the actuating ring. The first elastic element is sleeved on the outer side of the second connecting shell, and both ends of the first elastic element are respectively connected to the connecting protrusion and the pressing portion. The first elastic element is used to drive the pressing portion to press each of the locking balls inward.

[0015] Furthermore, the outer periphery of the actuating ring is provided with friction texture.

[0016] Furthermore, the gantry support frame includes a crossbeam and columns, the columns are arranged in pairs and fixed at both ends of the crossbeam, the crossbeam is provided with a mounting plate, and the lifting mechanism is mounted on the mounting plate.

[0017] Furthermore, the lifting mechanism includes a telescopic component, a guide rod, and a lifting plate.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0034] This embodiment proposes a gantry-type automatic multi-point adhesive application device for car door outer panels, such as... Figures 1 to 7 As shown, it includes a gantry support frame 1 and an adhesive application mechanism 5 and a lifting mechanism mounted on the gantry support frame 1. The lifting mechanism is used to drive the adhesive application mechanism 5 to move vertically up and down. The adhesive application mechanism 5 includes an adhesive application frame 55, an adhesive distribution plate, and an adhesive application tube 56. The adhesive distribution plate is mounted on the adhesive application frame 55. A first connector 2 is provided at the adhesive outlet of the adhesive distribution plate. A second connector 3 is provided at one end of the adhesive application tube 56. The first connector 2 and the second connector 3 can be engaged or disengaged. When the first connector 2 and the second connector 3 are engaged, the adhesive distribution plate and the adhesive application tube 56 are connected.

[0035] In this embodiment, the dispensing disc has a dispensing chamber inside, an opening at the top for connecting to a feed pipe, and several dispensing ports evenly distributed circumferentially along its sidewalls. Each dispensing port communicates with the dispensing chamber. Multiple dispensing tubes 56 are connected to each dispensing port. These multiple dispensing tubes 56 are connected to the dispensing disc via snap-fit ​​connections, allowing for orderly installation and forming a complete coating system. In practical applications, when assembling the dispensing tubes 56, the second connector 3 of the dispensing tube 56 and the first connector 2 of the dispensing disc engage with each other, tightly connecting the dispensing tube 56 and the dispensing disc. When a dispensing tube 56 reaches its service life limit and needs replacement, a specific operation is performed to detach the second connector 3 of that dispensing tube 56 from the first connector 2 of the dispensing disc, removing the dispensing tube 56 from the overall coating structure without affecting the normal use of other dispensing tubes 56.

[0036] In practical applications, the first connector 2 can be installed on the dispensing disc by means of thread or welding, and the second connector 3 can be installed on the dispensing tube 56 by means of thread or welding.

[0037] In a preferred embodiment, the first connector 2 includes a first connecting shell 21, a hollow first chamber 22 is formed inside the first connecting shell 21, and an annular snap-fit ​​groove 23 is provided on the first connecting shell 21.

[0038] The second connecting member 3 includes a second connecting shell 31, a snap-fit ​​member 32, and a lever member 33. The second connecting shell 31 has a hollow second chamber 34. The lever member 33 is slidably disposed on the first connecting shell 21. When the first connecting member 2 and the second connecting member 3 are engaged, the lever member 33 tends to drive the snap-fit ​​member 32 into the annular snap-fit ​​groove 23. Along the radial direction of the second connecting shell 31, several mounting grooves 35 are formed on the second connecting shell 31. The snap-fit ​​member 32 includes several snap-fit ​​balls 321, which are correspondingly installed in the corresponding mounting grooves 35.

[0039] A connecting protrusion 311 is formed on the outer periphery of the second connecting shell 31. The actuating member 33 includes a first elastic member 332 and an actuating ring 331. The first elastic member 332 is preferably a wave spring or a tower spring. A pressing part 3311 is formed on the inner side of the actuating ring 331. The first elastic member 332 is sleeved on the outer side of the second connecting shell 31, and both ends of the first elastic member 332 are connected to the connecting protrusion 311 and the pressing part 3311 respectively. When the first elastic member 332 is not subjected to external force, the pressing part 3311 is located at the mounting groove 35. The pressing part 3311 presses each locking ball 321 inward.

[0040] In a preferred embodiment, the outer periphery of the actuating ring 331 is provided with friction texture to increase friction and facilitate the movement of the actuating ring 331.

[0041] In this embodiment, the array of mounting grooves 35 radially opened in the second connecting shell 31 constitutes the radial movement track of the snap-fit ​​balls 321. Each snap-fit ​​ball 321 is fitted into an independent mounting groove 35 in a spherical-arc contact form, forming a multi-directional limiting node that can roll freely. When two filter units are docked, the first connecting shell 21 is inserted into the second connecting shell 31, and each snap-fit ​​ball 321 is snapped into the annular snap-fit ​​groove 23, forming a multi-spherical point contact locking. During disassembly, the actuating ring 331 is turned in the opposite direction, compressing the first elastic member 332, and the squeezing part 3311 moves to the left. At this time, the snap-fit ​​balls 321 are not subjected to inward squeezing and pull the first connecting member 2 outward. At this time, the annular snap-fit ​​groove 23 is released from the restriction of the snap-fit ​​balls 321, and the snap-fit ​​balls 321 and the annular snap-fit ​​groove 23 are released from engagement.

[0042] In a preferred embodiment, the gantry support frame 1 includes a crossbeam 11 and columns 12. The columns 12 are arranged in pairs and fixed to both ends of the crossbeam 11 to form a gantry structure. In this embodiment, a first diagonal support 13 is fixedly provided on the column 12, and the first diagonal support 13 is supported on the ground. A second diagonal support 14 is provided between the column 12 and the crossbeam 11. The two ends of the second diagonal support 14 are fixedly connected to the bottom of the crossbeam 11 and the surface of the column 12, respectively, so that the gantry support frame 1 can be stably supported on the ground. A mounting plate 15 is fixedly provided in the middle of the crossbeam 11, and a lifting mechanism is mounted on the mounting plate 15.

[0043] The lifting mechanism includes a telescopic component 41, a guide rod 42, and a lifting plate 44. The telescopic component 41 is fixedly installed on the top of the mounting plate 15. The telescopic end of the telescopic component 41 passes through the mounting plate 15 and is fixedly connected to the lifting plate 44. The glue application frame 55 is fixedly installed on the lifting plate 44. The guide rod 42 slides through the mounting plate 15. A guide sleeve 43 is fixedly provided on the mounting plate 15 for the guide rod 42 to pass through. The bottom end of the guide rod 42 is fixedly connected to the lifting plate 44. In this embodiment, the telescopic component 41 is a cylinder. By extending and retracting the cylinder, the lifting plate 44, the glue application frame 55, the glue dispensing disc, and the glue application tube 56 can be driven to rise and fall vertically. The guide sleeve 43 ensures that the glue application mechanism 5 does not deviate during the lifting process.

[0044] In the above embodiment, the dispensing disc includes a primary dispensing disc 51 and a secondary dispensing disc 52. The dispensing outlet of the primary dispensing disc 51 and the dispensing inlet of the secondary dispensing disc 52 are connected by a dispensing tube 57. Similarly, a second connector can be provided at both ends of the dispensing tube 57. A first connector 2 can be provided at the dispensing outlet of the primary dispensing disc 51 and the dispensing inlet of the secondary dispensing disc 52, so that the dispensing tube 57 and the primary dispensing disc 51, and the dispensing tube 57 and the secondary dispensing disc 52 are detachably connected. A second connector is provided at one end of the glue application tube 56, and a first connector is provided at the dispensing outlet of the secondary dispensing disc 52. One end of the glue application tube 56 is connected to the first connector 2 on the secondary dispensing disc 52 through a second connector 3. An automatic glue gun 53 is provided above the primary dispensing disc. A glue application tube 54 is connected to the glue inlet of the automatic glue gun 53, and the dispensing outlet of the automatic glue gun 53 is connected to the glue inlet of the primary dispensing disc 51. It also includes a controller, and the cylinder and automatic glue gun 53 are all electrically connected to the controller. The controller can calculate the time to achieve quantitative glue application.

[0045] Working principle:

[0046] Initial state: The cylinder is in the retracted state, the automatic glue gun at position 53 is closed, and the gantry-type automatic multi-point glue application device is in the waiting state.

[0047] Working state: The cylinder extends, and the glue application frame 55, primary glue distribution plate, glue distribution tube 57, automatic glue gun 53, glue inlet tube 54, secondary glue distribution tube 57 and glue application tube 56 descend to the designated position. The glue application mechanism 5 forms a multi-point glue application and descends to the glue application point on the front door outer panel. The automatic glue gun 53 opens, and the glue flows out to complete the metering and glue application.

[0048] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
