Description

Technical Field

[0001] The utility model relates to the technical field of gluing, in particular to a gluing device. Background Art

[0002] Gluing refers to the application of glue to products such as metals, plastics, and textiles. Once the glue solidifies and forms, it protects or enhances the product. Gluing can be divided into single glue and mixed glue. Mixed glue is made by blending multiple single glues, and is typically only mixed for actual use.

[0003] Currently, many products on the market still use manual glue guns to apply glue manually. Manual glue application has problems such as uneven coating thickness and the inability to accurately control the amount of glue output. In addition, when using mixed glue, the glue cures quickly, which easily clogs the mixing hose, requiring frequent replacement of the mixing hose and causing a waste of resources. Existing glue application devices can only apply glue to flat products and are unable to apply glue to complex curved surfaces or multi-sided products. The product application process requires manual flipping and moving of the product, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0051] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0052] Gluing is the process of applying glue to the surface of a product to protect and beautify it. It is widely used in the automotive, electronics, aviation, medical, and shipbuilding industries. Depending on the type of product being coated, the glue used is different. Depending on whether multiple single glues need to be mixed during use, glue can be divided into single glue and mixed glue. When using a single glue, only one glue cartridge is required, while mixed glue requires multiple glue cartridges, and multiple single glues are mixed during use. Currently, various manufacturers and businesses still rely heavily on manual gluing when applying glue to their products. Manual gluing results in uneven coating thickness and the inability to accurately control the amount of glue produced, resulting in poor product quality. Furthermore, operators cannot hold large equipment and can only use simple handheld glue guns. This is not only inefficient, but when using mixed glue, the glue quickly solidifies and can easily clog the mixing hose, requiring frequent replacement, which can easily lead to a waste of resources.

[0053] Based on the above, the gluing device provided in the embodiment of the present invention can solve the above problems, which will be described in detail below.

[0054] Please refer to Figures 1 to 3 The gluing device comprises an upper outer frame 1, a lower outer frame 2, a three-axis displacement device 3, a glue dispensing device 4, a rotating jig 5, and a controller. The upper and lower outer frames 1 and 2 form an enclosed space within which the three-axis displacement device 3, glue dispensing device 4, and rotating jig 5 are located, forming an integrated device. The upper outer frame 1 also protects the three-axis displacement device 3, glue dispensing device 4, and rotating jig 5 within the enclosed space. The lower outer frame 2 provides a mounting location for the three-axis displacement device 3, glue dispensing device 4, and rotating jig 5. The three-axis displacement device 3 drives the glue dispensing device 4 to move, allowing glue to be applied to different parts of a product 6. The glue dispensing device 4 applies glue to the product 6. The rotating jig 5 holds and positions the product 6 while rotating it, enabling the glue dispensing device 4 to apply glue to the product 6 without blind spots. The controller controls the glue output of the glue dispensing device 4, as well as the movement direction and speed of the three-axis displacement device 3 and the rotation speed of the rotating jig 5.

[0055] Among them, the glue dispensing device 4 includes a glue mixing structure 41, a glue pushing structure 42, and a refrigeration structure 43. The glue mixing structure 41 is used to mix multiple single glues to form a mixed glue. The glue pushing structure 42 is used to push the mixed glue out for coating. The refrigeration structure 43 is used to slow down the curing rate of the mixed glue to prevent the mixed glue from clogging the glue outlet channel.

[0056] The above-mentioned gluing equipment replaces manual gluing, which can greatly improve the gluing efficiency and ensure the gluing quality of product 6.

[0057] The upper outer frame 1 and the lower outer frame 2 of the glue coating device are described in detail below.

[0058] refer to Figure 1 The upper outer frame 1 includes an upper frame 10 , a top panel 11 and an upper side panel 12 . The top panel 11 is arranged on the top of the upper frame 10 , and the upper side panel 12 is arranged on the circumference of the upper frame 10 .

[0059] As an optional and more specific embodiment, the upper frame 10 is constructed by four vertically arranged vertical beams and eight horizontally arranged cross beams. The four vertical beams are equal in length and arranged parallel to each other. The cross beams are sequentially connected to the two ends of two adjacent vertical beams, thereby forming a regular quadrangular prism frame structure. The connection between the vertical beams and the cross beams can be made in a variety of forms such as welding, screw / bolt connection, mortise and tenon connection, etc. The vertical beams and the cross beams can be made into tubular shapes such as square tubes and round tubes, or other shapes, which are not limited here. The vertical beams and the cross beams can be made of metals such as iron and aluminum alloys, or can be cast and formed by plastics in combination with molds, or can be made of semi-finished materials such as angle steel and I-beams. The materials of the vertical beams and the cross beams can be selected according to actual needs.

[0060] As another optional and more specific embodiment, the upper frame 10 is constructed from a plurality of vertical beams and two circular ring beams. The two circular ring beams are connected to the ends of the vertical beams to form a cylindrical frame structure. The circular ring beams and the vertical beams can be connected by one or more of various methods, such as welding, screw / bolt connection, mortise and tenon connection, etc. The structure and material of the circular ring beams are not limited herein.

[0061] Of course, the upper frame 10 can also be made into other shapes. The above-mentioned regular quadrangular prism frame structure and cylindrical frame structure are only used as examples and are not used to limit the form of the upper frame 10.

[0062] Please continue to refer to Figure 1 A top mask 11 is provided on the top of the upper frame 10 , and the top mask 11 covers the top of the upper frame 10 . An upper side mask 12 is provided on the circumference of the upper frame 10 , and the upper side mask 12 covers the circumference of the upper frame 10 .

[0063] Specifically, the top panel 11 is connected to the upper frame 10 by adhesive bonding, screw connection, or snap connection. If snap connection is adopted, a slot is provided on the upper frame 10, and the top panel 11 is inserted into the slot. The upper side panel 12 is connected to the upper frame 10 by screws / bolts, thereby making the connection more reliable. The shapes of the top panel 11 and the upper side panel 12 are set according to the shape of the constructed upper frame 10. For example, when the upper frame 10 is a regular quadrangular prism frame structure, the top panel 11 and the upper side panel 12 are both rectangular panels. The top panel 11 and the upper side panel 12 can be made of plastic such as PVC, which has the advantage of being lightweight.

[0064] Please refer to Figure 2 The lower outer frame 2 includes a lower frame 20 , a lower side mask 21 , and a top substrate 22 . The top substrate 22 is arranged on the top of the lower frame 20 , and the lower side mask 21 is arranged on the circumference of the lower frame 20 .

[0065] Since the three-axis displacement device 3, the dispensing device 4 and the rotating fixture 5 need to be arranged on the top substrate 22, the top substrate 22 and the lower frame 20 are fixedly connected by welding or screw connection. At the same time, the top substrate 22 is made of a high-strength, low-deformation plate, such as aluminum alloy, which is conducive to ensuring stability and reliability during gluing.

[0066] In this embodiment, the lower frame 20 is a regular quadrangular prism frame structure, and the top substrate 22 and the lower side mask 21 are also rectangular plates. In other embodiments, the structures of the top substrate 22 and the lower side mask 21 are adaptively set according to the frame structure of the lower frame 20.

[0067] There are many ways to connect the lower side panel 21 and the lower frame 20, such as bonding, clamping, welding, screw / bolt connection or hinge connection.

[0068] Furthermore, to ensure stable placement of the gluing equipment even on uneven surfaces, the bottom of the lower frame 20 is equipped with multiple support legs 23. These support legs 23 are height-adjustable, allowing the gluing equipment to be positioned horizontally. Optionally, the support legs 23 include hydraulic telescopic cylinders that are controlled by injecting or withdrawing hydraulic fluid to adjust the gluing equipment. Of course, the support legs 23 can also be adjusted using other mechanisms, such as threaded adjustment.

[0069] The upper outer frame 1 and the lower outer frame 2 can be integrally formed or separately formed. When integrally formed, the upper outer frame 1 and the lower outer frame 2 are fixedly connected, and the upper frame 10 must match the lower frame 20 in terms of frame structure. When separately formed, the frame form of the upper frame 10 and the frame form of the lower frame 20 do not affect each other, and the connection form between the upper outer frame 1 and the lower outer frame 2 is also not restricted. For example, the upper frame 10 of the upper outer frame 1 can be directly connected to the lower frame 20, or it can be set on the top substrate 22.

[0070] Please refer to Figures 2 to 4 A three-axis displacement device 3, a dispensing device 4 and a rotating fixture 5 are provided on the upper part of the top substrate 22, wherein the three-axis displacement device 3 includes an X-axis displacement structure 30, a Z-axis displacement structure 31 and a Y-axis displacement structure 33. The three-axis displacement device 3 is used to drive the dispensing device 4 and the rotating fixture 5 to move, thereby applying glue to different parts of the product 6.

[0071] The X-axis displacement structure 30 further comprises columns 301, an X-axis mounting plate 302, an X-axis sliding cover 303, an X-axis slider 304, and an X-axis driver 305. The columns 301 comprise two columns, the bottoms of which are connected to the top base plate 22. The X-axis mounting plate 302 is mounted on top of the two columns 301, and the X-axis sliding cover 303 is disposed on the upper surface of the X-axis mounting plate 302. The X-axis sliding cover 303 defines a first chute along its longitudinal axis, on which the X-axis slider 304 is slidably mounted. The X-axis slider 304 is connected to the driving end of the X-axis driver 305.

[0072] Optionally, the X-axis slider 304 is connected to the driving end of the X-axis driving member 305 through a force transmission rod, and the X-axis driving member 305 is a push rod motor; the push rod of the push rod motor is connected to one end of the force transmission rod through an axis connector, and the other end of the force transmission rod is welded to the X-axis slider 304.

[0073] As another embodiment, the X-axis driving component 305 is a servo motor, which is connected to a screw rod through a shaft connector. The other end of the screw rod away from the servo motor is rotatably engaged with the X-direction slide cover 303 through a bearing; a threaded hole along the X-axis direction is opened on the X-direction slider 304, and the screw rod passes through the threaded hole on the X-direction slider 304 and can rotate. When the servo motor is working, it drives the screw rod to rotate. Since the screw rod only rotates and does not move, it drives the X-direction slider 304 to slide on the first slide groove of the X-direction slide cover 303.

[0074] In addition, in order to accurately measure and control the movement distance of the X-axis slider 304, an X-axis position sensor 306 for detecting the position of the X-axis slider 304 is also provided on the X-axis slide cover 303. The X-axis position sensor 306 communicates with the controller and is used to transmit the measured X-axis slider 304 position information to the controller in real time.

[0075] Please refer to Figure 4 and Figure 5 The Z-axis displacement structure 31 is connected to the X-axis slider 304 through the XZ connection structure 32.

[0076] The Z-axis displacement structure 31 includes a Z-fixing plate 311, a Z-sliding cover 312, a Z-sliding block 313, and a Z-axis driver 314. The long side of the Z-fixing plate 311 is oriented vertically. The Z-sliding cover 312 is connected to a side surface of the Z-fixing plate 311. The Z-sliding cover 312 has a second chute along its long axis. The Z-sliding block 313 slides in this second chute and is connected to the driving end of the Z-axis driver 314.

[0077] The connection between the Z-axis slider 313 and the Z-axis driver 314 is similar to that between the X-axis slider 304 and the X-axis driver 305. The Z-axis driver 314 can also utilize a push rod motor or a servo motor. For details on the connection and drive method, refer to the above-mentioned sections regarding the X-axis slider 304 and the X-axis driver 305. The difference between the X-axis slider 304 and the X-axis driver 305 and the Z-axis slider 313 and the Z-axis driver 314 is that the Z-axis driver 314 drives the Z-axis slider 313 in the Z-axis direction.

[0078] Similarly, in order to accurately measure and control the moving distance of the Z-direction slider 313, a Z-direction position sensor 315 for detecting the position of the Z-direction slider 313 is also provided on the Z-direction slide cover 312. The Z-direction position sensor 315 communicates with the controller and is used to transmit the measured Z-direction slider 313 position information to the controller in real time.

[0079] It should be noted that the XZ connection structure 32 includes an XZ connection plate 321 and an XZ support member 322. The XZ connection plate 321 is fixedly connected to the X-axis slider 304 and the Z-axis fixed plate 311 at the same time. When the X-axis slider 304 moves, it drives the Z-axis fixed plate 311 to move along the X-axis direction; the XZ support member 322 is arranged between the XZ connection plate 321 and the Z-axis fixed plate 311 to play a role in reinforcement and stability.

[0080] Unlike the Z-axis displacement structure 31 which is connected to the X-axis slider 304, the Y-axis displacement structure 33 is disposed on the top substrate 22. Figure 6 The Y-axis displacement structure 33 includes a Y-axis sliding cover 331 , a Y-axis slider 332 , a Y-axis driving member 333 and a Y-axis position sensor 334 .

[0081] Among them, the Y-direction sliding cover 331 is perpendicular to the long axis direction of the X-direction sliding cover 303 and the long axis direction of the Z-direction sliding cover 312. A third sliding groove is opened on the Y-direction sliding cover 331 along its own long axis direction. The Y-direction slider 332 is slidably set on the third sliding groove, and the Y-direction slider 332 is driven to slide by the Y-axis driving member 333.

[0082] The connection between the Y-axis slider 332 and the Y-axis driver 333 is similar to that between the X-axis slider 304 and the X-axis driver 305. The Y-axis driver 333 can also utilize a push rod motor or a servo motor. For details on the connection and drive method, refer to the above-mentioned sections on the X-axis slider 304 and the X-axis driver 305. The difference between the Y-axis driver 333 and the X-axis driver 305 is that the Y-axis driver 333 drives the Y-axis slider 332 in the Y-axis direction.

[0083] Correspondingly, a Y-direction position sensor 334 is provided on the Y-direction slide cover 331, and the Y-direction position sensor 334 is used to detect the position of the Y-direction slider 332 on the Y-direction slide cover 331 in real time; the Y-direction slider 332 communicates with the controller to transmit the measured Y-direction slider 332 position information to the controller in real time.

[0084] It should be noted that, in this embodiment, the X-direction sliding cover 303 and the X-direction slider 304 , the Y-direction sliding cover 331 and the Y-direction slider 332 , and the Z-direction sliding cover 312 and the Z-direction slider 313 cooperate in the same manner, including shape and driving method.

[0085] In addition to the above-mentioned use of the X-axis displacement structure 30, the Z-axis displacement structure 31 and the Y-axis displacement structure 33 to drive the dispensing device 4 to move, in other embodiments, the dispensing device 4 can also be moved in other ways, such as using a robotic arm to drive the dispensing device 4 to move.

[0086] In order to protect the communication cables and wires in the gluing equipment, an X-direction drag chain plate 308 is provided on the side of the X-direction mounting plate 302, and an X-direction drag chain 307 is arranged on the X-direction drag chain plate 308. At the same time, a Y-direction drag chain 335 is arranged on the top substrate 22. The communication cables and wires are arranged through the X-direction drag chain 307 and the Y-direction drag chain 335, thereby protecting the communication cables and wires.

[0087] The glue dispensing device 4 is the most important actuator in the glue coating equipment, which plays the role of mixing glue, discharging and coating glue. The glue dispensing device 4 is described in detail below.

[0088] Please refer to Figures 7 to 9 The glue dispensing device 4 includes a glue pushing base plate 40, a glue mixing structure 41, a glue pushing structure 42, and a cooling structure 43. The glue pushing base plate 40 is used to provide a mounting position for the glue mixing structure 41 and the glue pushing structure 42, and is connected to the Z-axis displacement structure 31. The glue mixing structure 41 is used to mix multiple single glues to form a mixed glue. Of course, if the glue to be applied is a single glue, only one glue is used without mixing. The glue pushing structure 42 is used to discharge the mixed glue or the single glue at a certain pressure to achieve the coating requirement.

[0089] One side surface of the rubber pushing base plate 40 is used to install and fix the rubber mixing structure 41 and the rubber pushing structure 42 , and the other side surface is fixedly connected to the Z-direction slider 313 so as to move together with the Z-direction slider 313 .

[0090] The glue mixing structure 41 includes a glue encapsulating body 411, a glue cylinder 412, and a glue mixing and discharging head 413. A glue storage chamber is provided in the glue cylinder 412 for storing glue; the number of glue cylinders 412 is set to multiple to facilitate mixing of multiple single glues. The multiple glue cylinders 412 are independently arranged and not interconnected. In this embodiment, the glue cylinders 412 are hollow cylinders, two in number, and arranged in parallel. In other embodiments, the glue cylinders can be other forms such as hollow prisms. The bottoms of the multiple glue cylinders 412 are connected to the glue mixing and discharging head 413, and the single glue is discharged from the glue cylinder 412 into the glue mixing and discharging head 413 to complete mixing. The glue encapsulating body 411 is provided on the outside of the glue cylinder 412 to protect the glue cylinder 412.

[0091] Continue to refer Figure 7 and Figure 8 The glue pushing structure 42 includes a push rod 421, a glue pushing driver 427, and a piston 4271. The two ends of the push rod 421 are respectively connected to the piston 4271 and the output end of the glue pushing driver 427. The piston 4271 is slidably disposed within the glue storage chamber of the rubber cylinder 412. The glue pushing driver 427 drives the push rod 421 to apply pressure to the glue in the rubber cylinder 412, causing the glue to be discharged at a certain pressure. It is worth mentioning that during the sliding cooperation between the piston 4271 and the glue storage chamber of the rubber cylinder 412, it is necessary to ensure that the piston 4271 and the inner side wall of the glue storage chamber are relatively sealed.

[0092] In one embodiment, the rubber push drive member 427 is a servo motor. The output shaft of the servo motor is connected to a threaded rod 425 via a shaft connector. The end of the threaded rod 425 away from the servo motor is connected to a threaded rod seat 424. A ball bearing is fixed to the threaded rod seat 424. The threaded rod 425 is sleeved and fixed on the ball bearing, so that the threaded rod 425 pushes the threaded rod seat 424 to move when the threaded rod 425 rotates. The threaded rod seat 424 is slidably connected to the basic connecting rod 401.

[0093] A front rubber pushing base 422 and a rear rubber pushing base 423 are also provided on the rubber pushing base plate 40. A threaded rod seat 424 is provided between the front rubber pushing base 422 and the rear rubber pushing base 423. The threaded rod 425 passes through the rear rubber pushing base 423 and is connected to the threaded rod seat 424. The push rod 421 passes through the front rubber pushing base 422 and is connected to the threaded rod seat 424, so that when the threaded rod seat 424 moves, it drives the push rod 421 to move.

[0094] A connecting guide rod 426 is further provided between the front rubber pushing base 422 and the rear rubber pushing base 423 , and the connecting guide rod 426 provides a guide for the sliding of the threaded rod seat 424 , thereby ensuring the smoothness of the rubber pushing process.

[0095] A rubber pushing driving component fixing seat 429 is provided on the rubber pushing rear base 423 , and the rubber pushing driving component 427 is arranged through the rubber pushing driving component fixing seat 429 .

[0096] In this embodiment, since the servo motor acts as the glue pushing drive 427, the rotation speed of the servo motor is generally fast. Therefore, in order to control the glue output amount and glue output rate, a planetary reducer 428 is connected to the output shaft of the servo motor. The rotation speed of the threaded rod 425 is reduced by the planetary reducer 428, and the planetary reducer 428 is connected to the shaft connector on the threaded rod 425.

[0097] In order to protect the threaded rod 425 and the threaded rod seat 424, a protective cover plate 401 is provided on the outside of the threaded rod 425. The protective cover plate 401 is provided on the outside of the threaded rod 425 and covers the front base 422 and the rear base 423 of the rubber pusher.

[0098] As another embodiment, the rubber pushing driving member 427 is an electric telescopic rod, and the end of the electric telescopic rod is connected to the push rod 421, thereby pushing the push rod 421 to move.

[0099] The above description of the rubber pushing structure 42 is merely an example and does not limit the structure and working mode of the rubber pushing structure 42. All rubber pushing structures 42 that can be used to pressurize the rubber in the rubber cylinder 412 fall within the protection scope of this embodiment.

[0100] The temperature of the glue discharged from the mixing and discharging head 413 affects the curing rate, so it is very necessary to control the temperature of the glue discharged from the mixing and discharging head 413. Due to different glue properties, the corresponding glue curing conditions are also different. Generally, the glue is easier to cure when the glue temperature is high and easier to cure when the glue temperature is low. When the glue temperature is high and easier to cure, a cooling component or refrigeration structure 43 is installed outside the mixing and discharging head 413; when the glue temperature is low and easier to cure, a heating component or insulation component is installed outside the mixing and discharging head 413 to reduce the curing rate of the glue. This embodiment uses the example of the glue temperature being high and easier to cure as an example to explain the refrigeration structure 43 in detail.

[0101] Optional, reference Figure 10 The refrigeration structure 43 includes a refrigeration plate 431, a refrigeration pad 433, and a refrigeration fin 435. One side surface of the refrigeration pad 433 is connected to the rubber pushing base plate 40, and the other side surface is connected to the refrigeration plate 431. The refrigeration fin 435 is in thermal contact with the refrigeration plate 431, and the mixing and dispensing head 413 is arranged on the refrigeration plate 431. The refrigeration fin 435 in this embodiment directly uses an electric refrigeration fin available on the market for cooling. The electric refrigeration fin is arranged at the junction of the refrigeration pad 433 and the refrigeration plate 431. The mixing and dispensing head 413 transfers the heat of the glue to the refrigeration plate 431, and the refrigeration plate 431 then transfers the heat to the electric refrigeration fin to complete the temperature reduction.

[0102] In order to improve the cooling efficiency of the glue in the mixed glue head 413, a water-cooled plate 436 is provided at the junction of the cooling pad 433 and the cooling plate 431, and the temperature is further reduced by the water-cooled plate 436. Optionally, since the cooling pad 433 is in contact with the cooling plate 431, heat will be transferred from the cooling plate 431 to the cooling pad 433, so a heat conductor 434 is provided between the cooling pad 433 and the water-cooled plate 436. The heat conductor 434 is a metal block, and the metal block is in contact with the water-cooled plate 436. A water inlet and a water outlet are provided on the water-cooled plate 436, and a water-cooled channel is provided inside the water-cooled plate 436. The water-cooled channel is connected to the water inlet and the water outlet at the same time. The water inlet and the water outlet are respectively connected to the external cold water source through two different hoses.

[0103] In order to accurately control the glue coating position, a needle cap 432 is connected to the cooling plate 431. One end opening of the needle cap 432 is connected to the glue mixing head 413, and the other end opening of the needle cap 432 is connected to the needle 437. The glue is coated on the product 6 through the needle 437.

[0104] When there is a higher pressure requirement for the glue discharged from the needle 437, a Y-type needle valve 447 is provided in the needle cap 432. The Y-type needle valve 447 has a three-way pipe structure. The first end of the Y-type needle valve 447 is connected to the mixing glue head 413, the second end of the Y-type needle valve 447 is connected to the needle 437, and the third end of the Y-type needle valve 447 is connected to the Y-type needle pressurizing device 44.

[0105] Specifically, refer to Figure 11 and Figure 12 The Y-type needle pressurizing device 44 includes a pressurizing member 442 , a needle fixing block 443 , an upper connecting rod 444 for the Y-type needle, and a lower connecting rod 445 for the Y-type needle.

[0106] Pressurizing element 442 is used to pressurize the adhesive within Y-type needle valve 447. The output end of pressurizing element 442 is connected to Y-type needle valve 447 via upper and lower connecting rods 444 and 445, transmitting pressure. Pressurizing element 442 is mounted on pressurizing element mounting base 441, which is a Z-shaped block. In this embodiment, pressurizing element 442 is an SDA12 thin-profile cylinder. Pressurizing element 442 is threadedly connected to pressurizing element mounting base 441 via bolts. Pressurizing element 442 is attached to the lower surface of pressurizing element mounting base 441, ensuring that the pressure output direction of pressurizing element 442 is vertical.

[0107] The needle fixing block 443 provides an installation position for the Y-type needle upper connecting rod 444, the Y-type needle lower connecting rod 445 and the Y-type needle valve 447, and at the same time limits the Y-type needle upper connecting rod 444 and the Y-type needle lower connecting rod 445 to move in only one direction, thereby limiting the direction in which the pressure applied by the pressure piece 442 is limited; the needle fixing block 443 is connected to the pressure piece mounting seat 441.

[0108] In addition, a locking piece 446 is provided on the side of the Y-type needle lower connecting rod 445, and the locking piece 446 is inserted into the side wall of the Y-type needle lower connecting rod 445, and one end of the locking piece 446 can be used to squeeze the Y-type needle valve 447; a pressure-applying piston rod is provided on the upper part of the Y-type needle valve 447, and one end of the locking piece 446 is connected to the side wall of the piston rod, so that the position of the piston rod can be controlled, and then the pressure value of the slurry can be adjusted.

[0109] Of course, the pressure-applying member mounting seat 441 can be directly fixed on the rubber pushing base plate 40, or it can be slidably matched with the rubber pushing base plate 40. When slidingly matched with the rubber pushing base plate 40, the pressure-applying member mounting seat 441 is slidably connected to the slide rail 448, and the slide rail 448 is fixed on the rubber pushing base plate 40. The purpose of setting the slide rail 448 is to adjust the position of the Y-type needle pressure device 44 on the rubber pushing base plate 40, so as to facilitate matching with mixed rubber heads 413 of different sizes.

[0110] The arrangement and composition of the above-mentioned dispensing device 4 are merely used as an example for illustration, and other devices that can achieve the same function as the above-mentioned dispensing device 4 are considered as extensions of this embodiment.

[0111] refer to Figures 13 to 15 The rotating fixture 5 is set on the Y-axis displacement structure 33. Specifically, the Y-axis displacement structure 33 is fixed on the Y-direction slider 332 and moves synchronously with the Y-direction slider 332.

[0112] The rotating jig 5 includes a gluing fixture 50, a jig fixing plate 51, and a rotating drive member 52. The gluing fixture 50 is used to clamp the product 6, the rotating drive member 52 is used to drive the gluing fixture 50 to rotate, and the jig fixing plate 51 is used to provide an installation position for the gluing fixture 50 and the rotating drive member 52 and to connect with the Y-axis slider 332.

[0113] The fixture fixing plate 51 is a rectangular flat plate. A fixed shaft support block 511 is provided on the side of the fixture fixing plate 51 away from the Y-slider 332. There are two fixed shaft support blocks 511, which are arranged along the long side of the fixture fixing plate 51. Rotating end blocks 512 are rotatably provided on top of the two fixed shaft support blocks 511. The two rotating end blocks 512 are arranged relative to each other on the inner side of the fixed shaft support blocks 511 and connected to the fixture mounting plate 513. The rotating drive member 52 is transmission-connected to one of the rotating end blocks 512, thereby driving the fixture mounting plate 513 to rotate around the rotating end block 512. Specifically, the rotating drive member 52 is a servo motor, and the output shaft of the servo motor is snap-connected to the rotating end block 512.

[0114] The gluing jig 50 is disposed on a jig mounting plate 513 , and when the jig mounting plate 513 rotates, the gluing jig 50 is driven to rotate.

[0115] refer to Figure 16 The gluing fixture 50 includes a product placement plate 501, an angle positioning block 502 and a side stop block 503. The product placement plate 501 is fixed on the fixture mounting plate 513. The angle positioning block 502 and the side stop block 503 are arranged in different areas on the product placement plate 501 for clamping the product 6 and limiting the product 6.

[0116] Specifically, two angle positioning blocks 502 are symmetrically arranged on the side walls of the product placement plate 501. The space between the two angle positioning blocks 502 is used to position the product 6 at a certain angle. Side blocks 503 are generally arranged outside the two angle positioning blocks 502 and work together with the angle positioning blocks 502 to limit the position of the product 6.

[0117] In order to prevent people from accidentally opening the equipment or inserting body parts into the equipment when the gluing equipment is working, a grating 15 is specially set at the switch door of the equipment, and an alarm 14 is set on the upper outer frame 1 or the lower outer frame 2 of the equipment. The grating 15 and the alarm 14 both communicate with the controller. When the grating 15 detects that foreign objects or human parts have been inserted into the equipment, the detection signal is transmitted to the controller, and the controller controls the alarm 14 to sound an alarm. The alarm 14 is a voice alarm.

[0118] Optionally, a device operating terminal 13 is provided on the outer wall of the upper outer frame 1 or the lower outer frame 2. The device operating terminal 13 is communicated with the controller. The operator can modify the parameters set by the controller through the device operating terminal 13. The device operating terminal 13 is a touch operation screen.

[0119] In addition, in order to facilitate operation, the gluing device can also be equipped with a remote control handle 16, which is communicatively connected to the controller. The remote control handle 16 can be used to remotely control the working state of the gluing device and adjust the working parameters of the gluing device.

[0120] Reference again Figure 2 In actual use, the glue coating equipment is equipped with a glue barrel 24 to receive the discharged glue from the front section before the glue coating is applied to the product 6. In this embodiment, the glue barrel 24 is arranged on the top base plate 22 via a barrel fixing bracket 25, and the barrel fixing bracket 25 is fixedly connected to the top base plate 22.

[0121] The controller is respectively connected to the alarm 14, the grating 15, the remote control handle 16, the X-axis driver 305, the X-axis position sensor 306, the Z-axis driver 314, the Z-axis position sensor 315, the Y-axis driver 333, the Y-axis position sensor 334, the rubber push driver 427, the power switch of the cooling plate 435, the pressure member 442, and the rotary driver 52. In this embodiment, the controller is programmed using a PLC. The encoded program is used to receive signals and send signals / commands. The encoded program is considered to be existing technology and can be easily implemented using existing programming languages. It will not be described in detail here.

[0122] In this embodiment, the controller is mounted on the lower surface of the top substrate 22 .

[0123] The working principle of the glue coating equipment provided by the embodiment of the utility model is as follows:

[0124] After checking that the equipment is in good condition, the product 6 is placed on the gluing fixture 50 and clamped and fixed, and the gluing equipment is started. The three-axis displacement device 3 drives the gluing device 4 to move the gluing needle 437 to the glue barrel 24, and the glue pushing drive 427 works to squeeze out the glue in the glue cylinder 412, thereby expelling the air in the needle 437 and filling the needle 437 with glue; the three-axis displacement device 3 drives the gluing device 4 to move again and place the gluing needle 437 above the product 6. The needle 437 contacts the surface of the product 6, and the three-axis displacement device 3 moves at a uniform speed, so that the needle 437 can evenly coat the glue on the surface of the product 6; when one side of the product 6 is glued, the rotating drive 52 works to indirectly drive the product 6 to rotate, and the gluing of the remaining parts of the product 6 is completed through the needle 437. During the entire gluing process, the cooling structure 43 adaptively adjusts the temperature of the discharged glue according to the type of glue, thereby reducing the solidification rate of the glue in the mixing and dispensing head 413 and the needle 437 .

[0125] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
