Description

Technical Field

[0001] This utility model relates to the field of glue coating machine technology, and in particular to an interlaced glue coating mechanism. Background Technology

[0002] A door panel gluing machine is a device that can spray glue onto door panels of different sizes and shapes. It typically uses glue to bond multiple panels together to form a single product. Traditional glue application, however, relies heavily on manual operation, which is labor-intensive, inefficient, results in uneven glue application, low precision, and is prone to errors.

[0003] Chinese patent CN215429966U discloses a fully automatic glue-applying machine, which discloses that "the glue-applying chamber includes a horizontally arranged guide rail, on which a glue-applying gun assembly is mounted, and a photoelectric sensor is installed inside the glue-applying chamber; the photoelectric sensor can accurately measure the length of each board to be sprayed, thereby controlling the start and end positions of the glue-applying gun assembly... A vision camera is set above the feeding conveyor line; the vision camera can measure the width of the board to be sprayed, thereby realizing automated production... The photoelectric sensor and the vision camera are connected to the control console, which controls the range of movement of the glue-applying gun assembly on the guide rail and the start and stop of glue application."

[0004] However, the glue-applying machine in this solution only has one glue-applying gun assembly, which moves horizontally along the guide rail to apply glue. But for wider door panels, the glue-applying width is limited, and the left-right reciprocating movement of a single guide rail cannot guarantee the glue-applying effect on the door panel. Utility Model Content

[0005] The purpose of this invention is to provide an interlaced coating mechanism to solve the problems existing in the prior art.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An interleaved coating mechanism includes a coating chamber, a coating assembly, a conveyor belt, a storage bin, a photoelectric sensor, a vision camera, and a control console. The coating assembly includes two sets of coating components of the same size, connected by a connecting component. The connecting component includes a support profile, a slide rail, and a motor. The two slide rails are located on both sides of the support profile, and the motor is located on the top of the support profile. A gear is mounted on the main shaft of the motor. Each coating component includes a rack, a slider, a support frame, and a nozzle assembly. The slider is slidably connected to the slide rail, and the rack meshes with the gear. The two sets of coating components are symmetrically arranged about the center of the gear.

[0008] Furthermore, the motor shaft of the motor points downwards, and a support base is provided between the motor and the support profile, with the motor base of the motor fixed to the support base.

[0009] Furthermore, the support profile is fixed to the support rod extending from the glue-coating chamber, and the length of the support profile is greater than the total length of the two racks.

[0010] Furthermore, the nozzle assembly includes a needle-top dispensing valve, and multiple needle-top dispensing valves are arranged in an array. The needle-top dispensing valves are connected to a storage tank via pipelines, and the control terminal of the needle-top dispensing valves is electrically connected to a control console.

[0011] Furthermore, the photoelectric sensor and the vision camera are electrically connected to the console.

[0012] Furthermore, the photoelectric sensor is located in the glue coating chamber, and the vision camera is located at the feed end of the conveyor belt.

[0013] The beneficial effects of this utility model are:

[0014] 1) The motor can keep rotating in both directions, causing the two rows of glue-applying components to move closer or further apart, so that the glue-applying path forms two sets of intersecting curves, increasing the glue-applying area on the top of the door panel and improving the glue-applying effect.

[0015] 2) The two sets of adhesive coating components form a long strip-shaped adhesive coating area. Depending on the width of the door panel, the motor drives the gears to rotate, which in turn drives the racks on both sides to move towards or away from each other. This causes the two sets of adhesive coating components to move closer or further apart, forming adhesive coating areas of different widths. The adhesive coating area is adjusted by moving the two sets of adhesive coating components left and right. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] See Figures 1-3 This utility model provides a technical solution:

[0022] like Figures 1-3 As shown, an interlaced glue-applying mechanism is described. The glue-applying machine in this solution is an automatic glue-applying machine, including a glue-applying chamber 1, a glue-applying assembly 2, a conveyor belt, a storage tank, a photoelectric sensor, a vision camera, and a control console. Since automatic glue-applying machines are a mature technology, the conveyor belt, storage tank, photoelectric sensor, vision camera, and control console are not shown in the figure. The structure is briefly described here: The conveyor belt passes through the bottom of the glue-applying chamber 1. A vision camera for identifying door panels is installed at the feed end of the conveyor belt. The glue-applying chamber 1 has a box-like structure. Only the frame structure of the glue-applying chamber 1 is shown in the attached figure. The box-like structure of the glue-applying chamber 1 reduces contamination. The glue-applying chamber 1 is equipped with a photoelectric sensor, which can detect the width of the door panel and identify the slots on the door panel, allowing the glue to skip the corresponding slots during application, avoiding glue waste. The glue-applying assembly 2 is connected to the storage tank, through which glue is supplied.

[0023] The adhesive coating assembly 2 includes two sets of adhesive coating components 3 of the same size and specifications. A connecting component 4 is provided between the two sets of adhesive coating components 3. The connecting component 4 includes a support profile 41, a slide rail 42, and a motor 43. The two sets of slide rails 42 are located on both sides of the support profile 41, and the motor 43 is located on the top of the support profile 41. A gear 44 is provided on the main shaft of the motor 43. The adhesive coating component 3 includes a rack 31, a slider 32, a support frame 33, and a gun head assembly. The slider 32 is slidably connected to the slide rail 42, and the rack 31 meshes with the gear 44. The two sets of adhesive coating components 3 are arranged symmetrically about the center of the gear 44.

[0024] Through the above technical solution, the two sets of glue-applying components 3 form a long strip-shaped glue-applying area. Depending on the width of the door panel, the motor 43 drives the gear 44 to rotate, which in turn drives the racks 31 on both sides to move towards or away from each other, thus making the two sets of glue-applying components 3 move closer or further apart, forming glue-applying areas of different widths. The glue-applying area is adjusted by moving the two sets of glue-applying components 3 left and right. At the same time, the gun head uses a needle-type dispensing valve 34, and the opening and closing of each needle-type dispensing valve 34 can be controlled by the control panel. Therefore, when the two rows of glue-applying components 3 are arranged side by side, only one set of needle-type dispensing valves 34 needs to be opened, reducing glue waste.

[0025] At the same time, the motor 43 can keep rotating in both directions, so that the two rows of glue-applying components 3 keep moving closer or further away, so that the glue-applying path forms two sets of intersecting curves, increasing the glue-applying area above the door panel and improving the glue-applying effect.

[0026] Furthermore, the motor 43 axis of the motor 43 is downward, and a support seat 45 is provided between the motor 43 and the support profile 41. The motor 43 seat of the motor 43 is fixed to the support seat 45 to keep the rotation of the motor 43 stable.

[0027] Furthermore, the support profile 41 is fixed to the support rod 11 extending inside the glue-coating chamber 1, and is fixed to the glue-coating chamber 1 by the support rod 11. At the same time, the length of the support profile 41 is greater than the total length of the two racks 31, and the slide rail 42 is provided with limit blocks on both sides to prevent the racks 31 from disengaging from the gears 44 when the glue-coating assembly 3 moves too far.

[0028] Furthermore, the photoelectric sensor and the vision camera are electrically connected to the console.

[0029] Through the above technical solution, after the door panel enters the glue application chamber 1, the control motor 43 adjusts the distance between the two sets of glue application components 3 to adapt to door panels of different widths; then the corresponding needle-top glue dispensing valve 34 is activated to apply glue. At the same time, when the photoelectric sensor detects a groove or hole on the door leaf, the corresponding needle-top glue dispensing valve 34 is closed. The glue dispensing is restarted after the grooved area moves away with the conveyor belt, which can effectively save glue.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
