[0010] By adopting the above technical solution, when a dispensing operation is required, the first adjustment component is activated. The first adjustment component is a rubber-coated wheel that abuts against a friction ring, and the rubber-coated wheel drives the friction ring to rotate. The rotating friction ring drives the platform to rotate, and the first fixture on the platform drives the workpiece to rotate. The dispensing mechanism cooperates with the rotating workpiece, which allows the adhesive to be coated more evenly on the inner wall of the workpiece.

After the revolution component moves the rotating ring block for a certain period of time or angle, the transfer component transfers the vacuum chamber to the support block, and the second jig carrying the workpiece is located inside the vacuum chamber. Next, the vacuum pumping component and the rotation component are activated. The rotation component drives the support block to rotate, and the second jig on the support block drives the workpiece to rotate, ensuring that the adhesive inside the workpiece is evenly distributed on the inner wall of the workpiece.

In this way, the second jig 54 with the workpiece will be located inside the vacuum chamber 55.

[0055] After the vacuum hood 55 contacts the support block 53, the third motor is started, causing the rotating ring block 52 to rotate. The support block 53 with the workpiece will move from the position marked as 2 to the position marked as 7.

When the support block 53 rotates, the vacuum generator is started at the same time. The vacuum generator's air intake pipe draws air from the negative pressure chamber, and then the air in the vacuum hood 55 will enter the negative pressure chamber. In this way, the air bubbles in the adhesive on the workpiece will be extracted, realizing the degassing operation. When the support block 53 with vacuum hood 55 and workpiece rotates to the position marked 7, the support block 53 stops rotating and the vacuum generator is activated so that the vacuum hood 55 is no longer under negative pressure; and the transfer assembly 58 is activated so that the first pneumatic gripper 43 in the transfer assembly 58 clamps the mounting block 59 on the vacuum hood 55 and transfers the vacuum hood 55 so that the vacuum hood 55 no longer touches the support block 53.

[0056] Start the third motor to rotate the support block 53 to the position marked 8. The position marked 8 is the unloading station of the defoaming device 5.

[0057] refer to Figure 1 and Figure 2The weighing device 62 includes an electronic scale connected to the main body.

[0058] The second transfer device 61 includes a second robotic arm fixed to the main body, and a second pneumatic gripper is provided on the second robotic arm. A camera is provided on the second robotic arm for scanning workpiece barcodes.

[0059] The second robotic arm drives the second pneumatic gripper to move, transferring the workpiece, which has completed defoaming and is located at the unloading station of the defoaming device 5, to an electronic scale for weighing to detect the weight of the adhesive. If the adhesive weight is unqualified, the first robotic arm transfers the workpiece out of the main body. When the camera scans the workpiece barcode, it acquires information about the workpiece, such as its model and initial weight. This information, combined with the weighing on the electronic scale, allows the determination of the adhesive weight.

[0060] refer to Figure 2 and Figure 13 The anti-sedimentation device 9 includes multiple units, each of which includes a fixed frame 91 fixedly connected to one side of the main body, and a sliding stage 92 slidably connected to the fixed frame 91. The sliding stage 92 can be pushed manually, or a linear motor module connected to the sliding stage 92 can be installed on the fixed frame 91.

[0061] Multiple rotating rollers 93 are rotatably connected to the sliding table 92. Two adjacent rotating rollers 93 support one workpiece, and the workpiece is laterally positioned on the two rotating rollers 93. A drive assembly 94 is provided on the sliding table 92. The drive assembly 94 includes a fifth motor connected to the sliding table 92, and the output shaft of the fifth motor is connected to the rotating rollers 93.

[0062] The first robotic arm transfers workpieces with standard adhesive weight from the electronic scale to two adjacent rotating rollers 93. The fifth motor is then activated, driving the rotating rollers 93 to rotate. Each pair of adjacent rotating rollers 93 will then rotate one workpiece, thus reducing adhesive sedimentation. Alternatively, the drive assembly 94 can be a motor belt, ensuring that each pair of adjacent rotating rollers 93 rotates one workpiece.

[0063] In this application, the workpiece is placed vertically on the first fixture 12 and the second fixture 54, and the workpiece is transferred to the first fixture 12 by a third robotic arm.

[0064] refer to Figure 14 The workpiece described in this application is a bowl-shaped workpiece, and the inner bottom wall of the bowl-shaped workpiece is arc-shaped.

[0065] This application also discloses a workpiece dispensing process, including the following steps.

[0066] S1: The workpiece that needs to be glued and has a barcode is transferred to the first jig 12 by the third robotic arm. The first motor 131 is started, so that the chain 133 drives the moving block 15 to rotate. The platform 11 on the moving block 15 drives the first jig 12 to move, and the first jig 12 will drive the workpiece.

[0067] S2: When the first fixture 12 moves the workpiece to below the heating cover 241, the electric actuator 232 is activated, causing the heating cover 241 to move closer to the platform 11. The infrared heating lamp 242 is positioned directly above the workpiece, heating the workpiece on the first fixture 12 to achieve heat treatment. Heating the workpiece ensures the adhesion between the adhesive and the product, while stabilizing the viscosity of the adhesive. The heating room temperature range of the heating cover 241 is 0-250 degrees Celsius, preferably 50-120 degrees Celsius.

[0068] S3: When the first fixture 12 moves the heated workpiece directly below the dispensing head 34, the first cylinder 831 is activated, causing the positioning block 82 to abut against the moving block 15 to position the first fixture 12. Then, the second cylinder 732 and the second motor 734 are activated, causing the rubber-coated wheel 72 to rotate the friction ring 71, which in turn causes the first fixture 12 on the platform 11 to rotate the workpiece. The workpiece rotation speed range is 0.1-500 rpm, preferably 10-50 rpm. Then, the dispensing head 34 enters the workpiece. As the dispensing head 34 sprays adhesive, the workpiece rotates, and the position of the dispensing head 34 changes, resulting in more even dispensing. The dispensing head 34 dispenses adhesive at a rate of 0.01-20 ml / s, preferably 0.05-5 ml / s. The amount of adhesive applied can be adjusted in segments by the dispensing time t, with a higher amount in the inner bottom ring and a gradually decreasing amount in each subsequent ring. The amount of adhesive on the inner wall of the workpiece is consistent. The total amount of adhesive dispensed per application is controlled by the system from 0.5-500 g, preferably 5-100 g / application. When the dispensing head 34 applies adhesive to the inner wall of the workpiece, the workpiece rotates, and the dispensing head 34 begins applying adhesive from its starting end to its ending end, applying adhesive in a spiral pattern to the inner wall and bottom of the workpiece. While the dispensing head 34 is applying adhesive to the workpiece, the infrared heating lamp 242 heats the workpiece located on another first fixture 12 to achieve heat treatment.

[0069] S4: The first fixture 12 moves the glued workpiece to the vicinity of the first pneumatic gripper 43, enabling the first pneumatic gripper 43 to hold the glued workpiece and transfer it to the loading station of the defoaming device 5, i.e., the support block 53 marked as 1 on the fixed table 51. During the movement of the glued workpiece from position marked as 2 to position marked as 7, the fourth motor 573 is activated, causing the second fixture 54 on the support block 53 to rotate the workpiece. The glue inside the workpiece undergoes high-speed centrifugal spraying, ensuring a uniform glue layer on the inner and bottom walls of the workpiece. The centrifugal rotation speed of the workpiece ranges from 100-6000 rpm, preferably 300-3000 rpm. While the workpiece is rotating, the vacuum generator operates. Under the combined action of centrifugal force and vacuum, the thin film of glue quickly removes air bubbles, ensuring a uniform, bubble-free glue layer on the workpiece, thus achieving centrifugal spraying and defoaming treatment. During the centrifugal coating and degassing process of the adhesive layer inside the workpiece, the vacuum hood 55 contacts the support block 53, meaning the support block 53 carrying the workpiece moves to position marked 2. The vacuum hood 55 then contacts the support block 53 again, and the support block 53 carrying the workpiece moves to position marked 7. The vacuum hood 55 then stops contacting the support block 53. The workpiece, after centrifugal coating and degassing, moves to the unloading station of the defoaming device 5, which is position marked 8.

[0070] S5: The second pneumatic gripper on the second robotic arm transfers the workpiece that has undergone centrifugal coating and defoaming treatment at the unloading station of the defoaming device 5 to the electronic scale for weighing; and the camera on the second robotic arm scans the barcode on the workpiece to detect whether the weight of the adhesive is qualified.

[0071] S6: The first robotic arm transfers the workpiece with the standard glue weight from the electronic scale to two adjacent rotating rollers 93. The two adjacent rotating rollers 93 drive one workpiece to rotate, which reduces glue sedimentation and keeps the workpiece in a uniform glue coating state for later use, so that the glue layer on the workpiece remains uniform when it enters the later drying stage.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
