[0024] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-2 As shown, the utility model is an automatic glue dispensing device for the bottom shell of a buzzer, comprising a material rack 1, a material moving mechanism 2, a glue dispensing mechanism 3, a visual camera mechanism 4, a glue dispensing moving mechanism 5, a real-time monitoring mechanism 6, a residual glue collecting mechanism 7, and a workbench 8; the material moving mechanism 2, the glue dispensing mechanism 3, the visual camera mechanism 4, the glue dispensing moving mechanism 5, the real-time monitoring mechanism 6, and the residual glue collecting mechanism 7 are located on the workbench 8, and the workbench 8 is provided with a display screen 81;

[0026] The bottom of the material rack 1 is connected to the material moving mechanism 2, and the material moving mechanism 2 can be two existing ball screw assemblies arranged perpendicular to each other, one of which is connected to the material rack 1, and the bottom shell of the ball screw assembly is connected to the other ball screw assembly. The two ball screw assemblies are driven by a motor to realize the longitudinal and lateral horizontal movement of the material rack 1.

[0027] like Figure 3 As shown, the material rack 1 is provided with a plurality of material placement cavities 11, and the material placement cavities 11 are used to place the collection plate 9, such as Figure 5 As shown, the buzzer bottom shells can be placed one by one in each collecting groove 91 of the collecting plate 9, which is convenient for positioning the glue dispensing position of the bottom shell. Setting a plurality of material placement cavities 11 can sequentially move and dispense multiple collecting plates 9, thereby improving the efficiency of glue dispensing on the production line.

[0028] A clearance groove 12 is provided on the side of the material placement cavity 11 , and the clearance groove 12 can provide operating space for clamping and placing the collecting plate 9 in the material placement cavity 11 .

[0029] The glue dispensing mechanism 3 and the visual camera mechanism 4 are located above the material rack 1; the glue dispensing mechanism 3 is connected to the glue dispensing moving mechanism 5, and the glue dispensing moving mechanism 5 can be an existing cylinder assembly, and the lifting and lowering of the glue dispensing mechanism 3 is controlled by the piston action of the cylinder.

[0030] like Figure 4 As shown, the glue dispensing mechanism 3 includes a glue dispensing syringe 31 and a driving member 33. The driving member 33 is located above the glue dispensing syringe 31, and a vent 34 is provided on the top of the driving member 33. The glue dispensing syringe 31 is an existing syringe structure, and clamping arms 33 are provided on both sides of the driving member 33. The push pin plate 32 of the glue dispensing syringe 31 is located between the two clamping arms 33.

[0031] The vent 34 of the driving member 33 is connected to an external vent pipe. The air valve connected to the vent pipe transmits the airflow to the driving member 33 according to the instructions of the terminal electric control box and the preset frequency. The push pin plate 32 is pressed downward by the air pressure to squeeze out the glue in the tube and hit the target position. Compared with the piston action of the traditional cylinder, the air pressure driving mode provides less thrust to the push pin plate 32, which is more suitable for small dispensing positions and extremely small dispensing operations, and is suitable for the dispensing operation characteristics of the buzzer bottom shell.

[0032] The clamp arm 33 is a movable clamp, which is an existing hinged clamp, so that the driving member 33 can be quickly disassembled and assembled above the glue dispensing syringe 31, so that the glue dispensing syringe 31 can be replenished with glue.

[0033] A reinforcing rib 35 is provided on the top of the driving member 33 to enhance the overall stability of the driving member 33 and prevent the driving member 33 from shaking as a whole when the vent 34 continuously delivers airflow, thereby affecting the dispensing effect.

[0034] The visual camera mechanism 4 can be an existing camera assembly. The camera is pointed downward to capture a panoramic view of the aggregate plate 9 before dispensing. All bottom shell positions on a single plate are photographed and uploaded to the terminal as a reference for dispensing.

[0035] The real-time monitoring mechanism 6 is located on the side of the dispensing mechanism 3. The real-time monitoring mechanism 6 includes a camera 61, and the camera of the camera 61 faces downward. The camera 61 takes real-time photos of the status of the material collecting plate 9 being dispensed, and uploads them to the terminal. The real-time monitoring mechanism 6 also includes a connecting rod 63 and an adjusting member 62. The adjusting member 62 is provided with an adjusting hole 64 and a fastening hole 65. The camera 61 is connected to one end of the adjusting member 62. The connecting rod 63 passes through the adjusting hole 64. The fastener (not shown) fixes the adjusting member 62 to the connecting rod 63 through the fastening hole 65. The connecting rod 63 is connected to the workbench 8. The fastener can be an existing screw. After loosening the fastener, the adjusting member 62 is rotated to adjust the angle of the camera of the camera 61 connected thereto, so as to adjust the camera range and position of the camera 61 according to the different distribution conditions of the bottom shells of different batches and different parameters on the material collecting plate 9.

[0036] The residual glue collection mechanism 7 includes a collection box 71 and a collection cylinder 72; the collection box 71 is connected to the collection cylinder 72, and the collection box 71 is located below the needle of the glue syringe 31. When glue is applied to the bottom shell, the collection box 71 is moved away from the glue syringe 31 by the action of the collection cylinder 72. When the bottom shell of a single collecting plate 9 is completely glued, the glue dispensing mechanism 3 is in a standby state, and the collection box 71 is extended to the bottom of the needle of the glue syringe 31 by the action of the collection cylinder 72. A small amount of residual glue in the needle of the glue syringe 31 drips into the collection box 71 due to gravity, so as to avoid the residual glue from directly dripping after long-term online operation and contaminating other equipment and components.

[0037] The residual glue collecting mechanism 7 further includes a connecting frame 73, the connecting frame 73 is provided with a card slot 74, a card edge 75 is provided on the top of the collecting box 71, the collecting box 71 is carded in the card slot 74 through the card edge 75, and the connecting frame 73 is connected to the collecting cylinder 72. The collecting cylinder 72 controls the movement of the connecting frame 73, and when replacing the collecting box 71, the collecting box 71 can be directly taken out upwards. The design of the card edge 75 and the card slot 74 can facilitate the rapid replacement of the collecting box 71.

[0038] The utility model discloses an automatic glue dispensing device for buzzer bottom shell. The bottom shells to be glued are placed one by one on the collecting plate 9 in batches. The collecting plate 9 is placed on the material placement cavity 11. The material transfer mechanism 2 transfers the collecting plate 9 to the bottom of the visual camera mechanism 4. The visual camera mechanism 4 takes pictures of all the bottom shells before glue dispensing, and the pictures are uploaded to the terminal and displayed on the display screen 81. Then, the material transfer mechanism 2 transfers the collecting plate 9 to the bottom of the glue dispensing mechanism 3. The terminal locates the bottom shell positions on all the plates according to the uploaded pictures according to the program setting, and sends instructions to the material transfer mechanism 2 to transfer the bottom shells to the glue dispensing positions one by one. To the bottom of the glue dispensing syringe 31, the glue dispensing moving mechanism 5 controls the lifting and lowering of the glue dispensing mechanism 3, that is, the needle of the glue dispensing syringe 31 drops during glue dispensing to facilitate glue dispensing. After the glue dispensing at a single point is completed, when the material moving mechanism 2 moves the collecting plate 9, the needle of the glue dispensing syringe 31 is slightly lifted up to prevent the needle from scratching the collecting plate 9 during displacement; when glue is dispensed on the bottom shell on a single collecting plate 9, the real-time monitoring mechanism 6 will take real-time glue dispensing images and upload them to the terminal. The two images before and during glue dispensing can be intuitively seen on the display 81, which is convenient for the operator to quickly compare and check whether there are any missing points or wrong points.
