[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0022] Example
[0023] like Figures 1-5 As shown, this embodiment proposes a double-layer bonding and sealing adhesive dispensing device, including a device body 1. The device body 1 is provided with a clamping component 2 and a dispensing component 3. The clamping component 2 is used to clamp a spherical workpiece and then the dispensing component 3 applies adhesive to seal the edge of the workpiece. The clamping component 2 includes a support shell 201, which is rotatably mounted on the device body 1. The support shell 201 has a sliding groove 207, and a screw 208 is rotatably mounted in the sliding groove 207. The screw 208 is provided with two spiral sections. A stepper motor 202 is fixedly mounted on the side of the support shell 201 with opposite spiral patterns. The output shaft of the stepper motor 202 is fixedly connected to one end of the screw 208 via a coupling, for driving the screw 208 to rotate forward and backward. Two sections of the screw 208 with opposite spiral patterns are threadedly connected to translation slides 203. A clamping seat 204 is fixedly connected to the translation slide 203. A semi-annular support platform is integrally formed on the clamping seat 204 for supporting both sides of the spherical workpiece. An adjustment mechanism 4 is provided on the support platform. The workpiece is clamped using the clamping assembly 2. During clamping, the stability of the clamping is improved by using the adjustment mechanism 4. After clamping, adhesive is applied to the workpiece using the dispensing assembly 3. During the dispensing process, the support shell 201 rotates to apply adhesive to the edges of the workpiece.
[0024] like Figure 3 , Figure 5As shown, the adjusting mechanism 4 includes an adjusting rod 401. A guide groove 211 is provided on the support platform of the clamping seat 204. The adjusting rod 401 is threaded into the guide groove 211. An abutment block 402 is slidably installed at one end of the guide groove 211 near the center of the support platform. The abutment block 402 has an arc-shaped contact surface near the workpiece, and its surface is coated with a wear-resistant rubber layer to enhance the fit with the workpiece. A spring 403 is provided between the adjusting rod 401 and the abutment block 402. One end of the spring 403 is fixedly connected to the adjusting rod 401, and the other end is fixedly connected to the abutment block 402. By rotating the adjusting rod 401, the distance between the adjusting rod 401 and the abutment block 402 is adjusted, thereby adjusting the compression degree of the spring 403. This allows the abutment block 402 to further clamp the workpiece. Through the elastic deformation of the spring 403, the abutment block 402 applies an adjustable flexible clamping force to the workpiece, avoiding damage to the workpiece from rigid clamping.
[0025] like Figure 3 As shown, the clamping assembly 2 also includes soft pads 209. A plurality of soft pads 209 are arranged and installed on the annular sidewall of the bearing platform of the clamping seat 204. The soft pads 209 have an arc-shaped structure. By setting the soft pads 209, damage to the workpiece can be avoided when the clamping seat 204 clamps the workpiece.
[0026] like Figure 2 , Figure 3 As shown, a vacuum pump 205 is fixedly connected to the top center of the support shell 201, and a vacuum suction cup 206 is fixedly connected to the vacuum pump 205. The vacuum suction cup 206 has a groove that matches the bottom of the workpiece. A vacuum channel is provided inside the vacuum suction cup 206, and the vacuum channel is connected to the vacuum pump 205 through a pipe.
[0027] like Figure 1 , Figure 2 As shown, a servo motor 210 is fixedly connected inside the main body 1 of the device. The output end of the servo motor 210 is fixedly connected to the support shell 201. The servo motor 210 drives the support shell 201 to rotate 360°, thereby performing glue application on the edge of the workpiece.
[0028] like Figure 1 , Figure 4 As shown, the device body 1 is also equipped with a dispensing pump. The dispensing assembly 3 includes a lifting rod 301, which is fixedly connected to the device body 1. The lifting rod 301 is located above the center of the support shell 201. The output end of the lifting rod 301 is fixedly connected to a guide rail 302. A pressure plate 303 is rotatably installed at the end of the guide rail 302 away from the lifting rod 301.
[0029] A telescopic rod 304 is slidably mounted on the guide rail 302. The telescopic end of the telescopic rod 304 is fixedly connected to a dispensing head 305. The dispensing head 305 is connected to a dispensing pump inside the main body 1 through a pipe. By using the lifting rod 301 to drive the pressure plate 303 to press down, the pressure plate 303 presses down on the inner bottom side of the workpiece during the pressing process, improving the stability of the workpiece and preventing shaking during rotation. Before dispensing, the position and telescopic length of the telescopic rod 304 are adjusted so that when the pressure plate 303 presses down on the workpiece, the dispensing head 305 is located diagonally above the dispensing position, thereby performing continuous dispensing operations.
[0030] Working principle: First, the position of the sliding telescopic rod 304 on the guide rail 302 is adjusted according to the size of the workpieces in the same batch, and the telescopic length of the telescopic rod 304 is adjusted so that the dispensing head 305 is positioned diagonally above the workpiece to be dispensed. The dispensing head 305 is connected to the dispensing pump in the main body 1 through a pipe. The spherical workpiece is placed on the vacuum suction cup 206 on the top of the support shell 201, with the bottom of the workpiece fitting into the groove of the vacuum suction cup 206. At the same time, the two sides of the workpiece are placed on the semi-circular support platform of the clamping seat 204. The stepper motor 202 is started to drive the screw 208 to rotate. The two spiral threads with opposite directions on section 8 are threadedly connected to the two translation slides 203, causing the two translation slides 203 to move closer to each other along the slide groove 207. This, in turn, causes the bearing platform of the clamping seat 204 to initially clamp the workpiece from both sides. Subsequently, by rotating the adjusting rod 401 of the adjusting mechanism 4, the distance between the adjusting rod 401 and the abutment block 402 is adjusted, causing the spring 403 to compress. The elastic force of the spring 403 pushes the abutment block 402 to further flexibly clamp the workpiece. At the same time, the soft pad 209 on the bearing platform of the clamping seat 204 prevents damage to the workpiece during the clamping process. During this process, the start-up... The vacuum pump 205 uses the vacuum channel within the vacuum suction cup 206 to adsorb the bottom of the workpiece, enhancing its clamping stability. Before dispensing, the lifting rod 301 is activated, causing the guide rail 302 to move downwards, gradually bringing the pressure plate 303 closer to the workpiece and ultimately pressing down on its inner bottom side. This further improves the workpiece's stability during subsequent rotation, preventing wobbling. During dispensing, the servo motor 210 is activated, rotating the support shell 201, allowing the clamped workpiece to rotate 360° with the support shell 201. Simultaneously, the dispensing pump operates, delivering the adhesive through a pipeline to the dispensing head. 305. The dispensing head 305 continuously dispenses adhesive onto the edge of the rotating workpiece to complete the double-layer bonding and sealing process. After dispensing, the servo motor 210 stops working, the support shell 201 and the workpiece stop rotating, the lifting rod 301 drives the guide rail 302 to rise, causing the pressure plate 303 to detach from the workpiece, the stepper motor 202 reverses, driving the screw 208 to rotate in the opposite direction, causing the two translation slides 203 to move away from each other, the clamping seat 204 releases the workpiece, the vacuum pump 205 stops working, and the vacuum suction cup 206 releases the workpiece. At this time, the dispensed workpiece can be removed, and the equipment completes one work cycle.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
