[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figure 1-5 As shown, a clamping and rotating dispensing and testing mechanism is provided, which includes: a base 1, a Y-axis linear module 2, a clamping and rotating device 3, and a dispensing and testing device 4.

[0025] The base 1 serves as the support for the entire mechanism.

[0026] The Y-axis linear module 2 is mounted on the base 1; the clamping rotation device 3 includes a bracket 31 mounted on the Y-axis linear module 2 and driven by the Y-axis linear module 2 to move in the Y-axis direction, an R-axis rotation module 32 mounted on the bracket 31, a carrier 33 mounted on the R-axis rotation module 32 and driven by the R-axis rotation module 32 to rotate and for carrying products, and a clamping module 34 cooperating with the carrier 33 to clamp and position products; the dispensing detection device 4 includes a frame 41, and a component mounted on the frame 41. An X-axis linear module 42, a Z-axis drive module 43 mounted on the X-axis linear module 42 and driven by the X-axis linear module 42 to move in the X-axis direction, a lifting seat 44 mounted on the Z-axis drive module 43, a dispensing assembly 45 mounted on the lifting seat 44, a height detection module 46 for detecting the height of the product, and an AOI detection module 47 for detecting the dispensing effect of the product, all of which are located above the carrier 33. In use, the product is placed on the carrier 33, and the clamping module 34, in conjunction with the carrier 33, clamps and positions the product. The Y-axis linear module 2 drives the carrier 33 and the product it carries to move below the dispensing detection device 4. The height detection module 46 then detects the height of the dispensing position on the front of the product, controlling the X-axis linear module 42 and the Z-axis drive module 43 to move the lifting seat 44 downwards, bringing the dispensing assembly 45 close to the dispensing position on the front of the product. The Y-axis linear module 2 drives the product to move, while the X-axis linear module 42 drives the dispensing assembly 45 to move. The dispensing assembly 45 then applies dispensing or coating to the dispensing position on the front of the product. Finally, the AOI detection module 47 inspects the dispensing effect on the front of the product. After testing, the Z-axis drive module 43 drives the dispensing assembly 45 to rise away from the front of the product. Then, the R-axis rotation module 32 drives the carrier 33 and the product it carries to rotate, so that the area on the back of the product that needs to be dispensed faces upward. Then, the height detection module 46 detects the height of the area on the back of the product that needs to be dispensed, so as to control the X-axis linear module 42 and the Z-axis drive module 43 to drive the lifting seat 44 to move downward into place, so that the dispensing assembly 45 is close to the area on the back of the product that needs to be dispensed. The Y-axis linear module 2 drives the product to move, and at the same time, the X-axis linear module 42 drives the dispensing assembly 45 to move. The dispensing assembly 45 then performs dispensing or coating treatment on the area on the back of the product that needs to be dispensed. Finally, the AOI detection module 47 detects the dispensing effect on the back of the product.This invention enables X, Y, Z, and R axis movement / rotation for multi-axis automatic dispensing, allowing for dispensing on both sides of the product. It is extremely simple to operate, highly efficient, reduces processes, and lowers costs. Furthermore, it employs a height detection module 46 to detect the height of the dispensing positions on both sides of the product, precisely controlling the dispensing assembly 45 to achieve accurate dispensing. Simultaneously, an AOI detection module 47 is used to inspect the dispensing effect on both sides of the product, eliminating the need for additional testing equipment for dispensing quality checks. This reduces costs, increases production efficiency, and enhances market competitiveness.

[0027] The carrier 33 is provided with product placement positions 331 for placing products, and the bottom surface of the carrier 33 is also provided with several windows 332 that pass through the product placement positions 331 to expose the glue application position on the reverse side of the product. When the product is placed in the product placement position 331, the glue application position on the reverse side of the product is exposed in the window 332.

[0028] The R-axis rotation module 32 is driven by a stepper motor, and the shaft of the stepper motor is connected to the clamping module 34 so that the clamping module 34 is driven to rotate by the shaft of the stepper motor.

[0029] The base 1 is also provided with a product sensor 11 for detecting whether a product is loaded on the carrier 33. The product sensor 11 is arranged from bottom to top and faces the window 332 of the carrier 33. When the product sensor 11 senses that a product is placed in the product placement position 331 on the carrier 33, the clamping module 34 works to cooperate with the carrier 33 to clamp and position the product.

[0030] The structure of the clamping module 34 is described in detail below:

[0031] The clamping module 34 includes a left clamping block 341 and a right clamping block 342 distributed on both sides of the carrier 33, and a clamping cylinder 343 for driving the left clamping block 341 and the right clamping block 342 to clamp or open with each other. The clamping cylinder 343 is fixed on the R-axis rotating module 32. The clamping cylinder 343 drives the left clamping block 341 and the right clamping block 342 to close with each other to clamp the product on the carrier 33, thereby achieving the purpose of clamping and positioning.

[0032] To better clamp the product on the carrier 33, the clamping module 34 has been further improved: the left clamping block 341 is provided with a first clamping block 344 whose relative position is adjustable, and the right clamping block 342 is provided with a second clamping block 345 whose relative position is adjustable. The inner sides of both the first clamping block 344 and the second clamping block 345 extend from the outside to the inside into the product placement position 331 to clamp the product. Preferably, the first clamping block 344 and the second clamping block 345 are made of elastic material (such as rubber, TPU, silicone, etc.).

[0033] The dispensing assembly 45 includes a lifting module 450 mounted on a lifting base 44, a fixing frame 451 mounted on the lifting module 450, and a dispensing syringe 452 mounted on the fixing frame 451. When the dispensing assembly 45 is working, the lifting module 450 drives the dispensing syringe 452 to move downward. The lifting module 450 is a cylinder. The fixing frame 451 is also equipped with a liquid level sensor 453 for detecting the liquid level of the dispensing syringe 452. The liquid level sensor 453 detects the liquid level of the dispensing syringe 452 in real time, so that when the liquid level of the dispensing syringe 452 drops to a set value, it can prompt the operator to replenish the dispensing syringe 452 with glue in time.

[0034] The dispensing components 45 are in two sets, arranged side by side on the lifting base 44. They can work together to simultaneously dispense glue to two dispensing positions on the product, or be used alternately to increase the dispensing cycle. Furthermore, while one dispensing component 45 is dispensing, it is convenient to replenish glue to the other dispensing component 45 that is low on glue, thus improving work efficiency. The height detection module 46 includes a distance sensor mounted on the lifting base 44 in an adjustable relative position. This distance sensor can directly detect the height of the dispensing positions on both sides of the product.

[0035] The AOI inspection module 47 includes a base plate 471 mounted on a lifting seat 44, a first adjusting seat 472 mounted on the base plate 471 with adjustable vertical position, a camera 473 mounted on the first adjusting seat 472, a second adjusting seat 474 mounted on the base plate 471 with adjustable vertical position, and a ring light source 475 mounted on the second adjusting seat 474, the ring light source 475 being located below the camera 473. A lens is also mounted on the lower end of the camera 473 to improve image quality. During operation, the ring light source 475 emits light to illuminate the front and back of the product, thereby improving the image quality of the camera 473 and enabling better detection of dispensing quality.

[0036] The base 1 is also equipped with a cleaning module 5 for cleaning the tip of the dispensing syringe 452 in the dispensing assembly 45. After each dispensing operation, the tip of the dispensing syringe 452 is moved to the cleaning module 5 by the X-axis linear module 42 and the Z-axis drive module 43, so as to cooperate with the cleaning module 5 to clean the tip of the dispensing syringe 452 and improve the quality of the next dispensing operation.

[0037] Specifically, the cleaning module 5 includes a support base 51 mounted on the base 1, a first rotating wheel 52 and a second rotating wheel 53 rotatably mounted on the support base 51, a motor mounted inside the support base 51 for driving the second rotating wheel 53 to rotate, a cleaning seat 54 mounted on the support base 51, a first guide rod 55 disposed between the cleaning seat 54 and the first rotating wheel 52, a second guide rod 56 disposed between the cleaning seat 54 and the second rotating wheel 53, a third guide rod 57 disposed outside the cleaning seat 54, and a cleaning seat that sequentially passes around the first rotating wheel 52, the first guide rod 55, the cleaning seat 54, the third guide rod 57, and the cleaning seat. 54. The cleaning strip 58 of the second guide rod 56 and the second rotating wheel 53: a clean cleaning strip is wound inside the first rotating wheel 52. One end of the cleaning strip passes sequentially around the first rotating wheel 52, the first guide rod 55, the cleaning seat 54, the third guide rod 57, the cleaning seat 54, the second guide rod 56, and the second rotating wheel 53. The motor drives the second rotating wheel 53 to rotate, pulling the cleaning strip to move. When the tip of the dispensing syringe 452 moves to contact the surface of the cleaning strip, the moving cleaning strip rubs against the tip of the dispensing syringe 452, thus cleaning the tip of the dispensing syringe 452 and removing any residual adhesive. Because of the addition of the first guide rod 55, the second guide rod 56, and the third guide rod 57, the cleaning strip can pass through the cleaning seat 54 twice to clean both sides of the tip of the dispensing syringe 452, resulting in better cleaning effect and higher cleaning efficiency.

[0038] The cleaning seat 54 has a channel 541 through which the cleaning strip 58 passes, and the inner walls on both sides of the channel 541 are provided with adjustable cleaning blocks 542. The cleaning blocks 542 protrude from the channel 541 and push the cleaning strip 58 outward from the outside, so that the cleaning strip 58 can better contact the two sides of the needle tip of the dispensing syringe 452 and perform cleaning, resulting in better cleaning effect and higher cleaning efficiency.

[0039] The support base 51 is also provided with a collection bucket 59 for collecting the adhesive produced after the cleaning strip 58 cleans the tip of the dispensing syringe 452. The collection bucket 59 collects the adhesive produced after the cleaning strip 58 cleans the tip of the dispensing syringe 452, ensuring cleanliness.

[0040] In summary, this invention enables X, Y, Z, and R axis movement / rotation for multi-axis automatic dispensing, allowing for dispensing on both sides of the product. The operation is extremely simple, with very high efficiency, and it also reduces processes and costs. Furthermore, this invention employs a height detection module 46 to detect the height of the dispensing positions on both sides of the product, precisely controlling the movement of the dispensing assembly 45 to achieve accurate dispensing. Simultaneously, an AOI detection module 47 is used to inspect the dispensing effect on both sides of the product, eliminating the need for additional testing equipment for dispensing quality inspection. This reduces costs and improves production efficiency, resulting in stronger market competitiveness.
