Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Please refer to Figures 1 to 5As shown, in this embodiment of the invention, a dispensing device is provided. The dispensing device includes a worktable 1, a dispensing device 2, and a product conveying device 3. The worktable 1 has a dispensing position. The dispensing device 2 is disposed on the worktable 1 and is used to dispense glue onto the product located at the dispensing position. The product conveying device 3 is also disposed on the worktable 1 and is used to transport the undispensed product to the dispensing position and to transport the product away from the dispensing position after the dispensing device 2 completes the dispensing operation.

[0035] The dispensing device 2 includes multiple dispensing work groups 21. Each dispensing work group 21 includes a dispensing valve 211, a detection unit 212, and an adjustment mechanism 213. The adjustment mechanism 213 is set on the workbench 1. The dispensing valve 211 and the detection unit 212 are both set at the adjustment end of the adjustment mechanism 213. The adjustment mechanism 213 is used to adjust the horizontal position and vertical height of the dispensing valve 211 and the detection unit 212. The dispensing valve 211 is used to apply the adhesive to the product.

[0036] Specifically, the workbench 1 refers to a supporting component with a certain height. The top surface of the workbench 1 is provided with a mounting surface for installing other components. The product conveying device 3 refers to a component or assembly that can transport products. The product conveying device 3 can be a conveyor belt or a robotic arm, etc. The dispensing device 2 refers to a component or assembly that can dispense adhesive onto the product. The dispensing device 2 can include multiple dispensing work groups 21. Each dispensing work group 21 includes a dispensing valve 211, a detection unit 212, and an adjustment mechanism 213.

[0037] The dispensing valve 211 refers to a component or assembly that achieves precise dispensing of adhesive through pneumatic or electric drive. The dispensing valve 211 is typically connected to the adhesive supply device via piping. The detection unit 212 refers to a device or assembly capable of acquiring images of a designated area, such as a CCD (Charge-coupled Device) vision inspection device. The detection unit 212 may also include a lens to make the images acquired by the CCD vision inspection device clearer. The adjustment mechanism 213 refers to a component or assembly capable of adjusting the position of an object. The adjustment mechanism 213 can adjust the horizontal and vertical positions of the dispensing valve 211 and the detection unit 212.

[0038] The dispensing equipment provided in this embodiment of the invention features a dispensing position on a workbench 1, and a product transport device 3 and a dispensing device 2 are mounted on the workbench 1. The dispensing device 2 is divided into multiple dispensing work groups 21, each including a dispensing valve 211, a detection unit 212, and an adjustment mechanism 213. During operation, the product transport device 3 transports undispensed products to the dispensing position, and the adjustment mechanism 213 drives the dispensing valve 211 to dispense the products at the dispensing position. After the dispensing device 2 completes the dispensing operation, the products are removed from the dispensing position. Compared with existing dispensing equipment, the multiple dispensing work groups 21 can perform synchronous or asynchronous dispensing during the dispensing operation, thereby improving the efficiency of the dispensing work. Meanwhile, each dispensing work group 21 is equipped with an independent dispensing valve 211 and a detection unit 212. While the dispensing work group 21 is performing dispensing work, the detection unit 212 can identify the position of the chip on the product in real time. This not only ensures the dispensing efficiency of the dispensing equipment, but also improves the accuracy of the dispensing equipment during dispensing.

[0039] It should be noted that the dispensing valve 211 can use a high-precision valve body. The minimum dispensing resolution of the dispensing valve 211 is 0.001μL, and the stable minimum dispensing amount is 0.02μL. It is suitable for cutting-edge COB dual-color temperature dispensing processes, and can precisely control the dispensing in zones to avoid the loss of control of phosphor color temperature caused by small-size dispensing.

[0040] It can also be configured with a new high-speed image processing unit to improve response speed, and use a brand-new visual alignment algorithm to process the images acquired by the detection unit 212, providing higher accuracy and long-term stability, and more closely integrating with machine vision and motion control technology, so as to meet the higher requirements of chip dispensing.

[0041] In one specific embodiment, please refer to Figure 4 The number of dispensing work groups 21 can be two. By setting two dispensing work groups 21, the two dispensing work groups 21 can be arranged at intervals along the product transport direction. This can simplify the overall structure of the dispensing equipment while ensuring its working efficiency.

[0042] In one embodiment, see Figure 4The adjustment mechanism 213 includes a base 2131, a first adjustment part 2132, a second adjustment part 2133, and a mounting base 2134. The base 2131 is disposed on the workbench 1. The first adjustment part 2132 is slidably disposed on the base 2131. A first driving unit is also disposed between the first adjustment part 2132 and the base 2131. The first driving unit is used to drive the first adjustment part 2132 to slide along a first direction. The second adjustment part 2133 is slidably disposed on the first adjustment part 2132. A second driving unit is also disposed between the second adjustment part 2133 and the first adjustment part 2132. The second driving unit is used to drive the second adjustment part 2133 to slide along a second direction. The second direction is set at an angle to the first direction. The mounting base 2134 is slidably disposed on the second adjustment part 2133. A third driving unit is also disposed between the mounting base 2134 and the second adjustment part 2133. The third driving unit is used to drive the mounting base 2134 to slide along a vertical direction.

[0043] Specifically, the base 2131 refers to a component with a certain volume, which can be block-shaped, plate-shaped, or column-shaped. The first adjusting part 2132, the second adjusting part 2133, and the mounting base 2134 all refer to components with a certain volume, and their shapes can be block-shaped, plate-shaped, or a combination of various shapes. A sliding structure can be provided between the first adjusting part 2132 and the base 2131, and a sliding structure can also be provided between the second adjusting part 2133 and the first adjusting part 2132. Similarly, a sliding structure is also provided between the second adjusting part 2133 and the mounting base 2134. The sliding structure can be a slide rail slider structure, etc. The first driving unit, the second driving unit, and the third driving unit all refer to components or assemblies that can drive an object to reciprocate along a linear direction. They can be cylinders, hydraulic cylinders, or electric push rods, or they can be screw-slider structures or cam-crank structures, etc.

[0044] In this embodiment, by mounting the dispensing valve 211 and the detection unit 212 on the mounting base 2134, when the dispensing valve 211 and the detection unit 212 need to move, the first driving unit can drive the first adjusting part 2132 to move along the first direction, the second driving unit can drive the second adjusting part 2133 to move along the second direction, and the third driving unit can drive the mounting base 2134 to move along the vertical direction. The first direction and the second direction can both be directions in the horizontal plane, and the angle between the first direction and the second direction can be a right angle. This allows the dispensing valve 211 and the detection unit 212 to move in space, making the position adjustment of the dispensing valve 211 and the detection unit 212 more convenient.

[0045] In an optional embodiment, please refer to Figure 4The base 2131 can be made of marble. Using marble to make the base 2131 gives it the advantages of low elastic deformation and strong vibration resistance. At the same time, marble also has an extremely low coefficient of thermal expansion, which can keep the installation of the adjustment mechanism 213 stable.

[0046] In one embodiment, see Figure 4 The first and second drive units are both linear drive motors, and the third drive unit is a KK linear module. Specifically, a linear drive motor is a type of motor that directly converts electrical energy into linear motion mechanical energy without the need for intermediate conversion mechanisms such as gears or lead screws. Therefore, it is widely used in scenarios requiring high precision, high speed, and high dynamic response. Compared to traditional rotary motors, it completely changes the indirect drive mode of "converting rotary motion into linear motion," significantly improving system efficiency and control precision. The KK linear module is a high-precision linear transmission device composed of a ball screw and a U-shaped linear guide rail, characterized by high precision, high speed, and low noise. In this embodiment, by using linear drive motors for both the first and second drive units and a KK linear module for the third drive unit, the adjustment precision of the adjustment mechanism 213 on the dispensing valve 211 is improved.

[0047] In an optional embodiment, please refer to Figure 4 A grating ruler is provided between the first adjustment part 2132 and the base 2131, and between the first adjustment part 2132 and the second adjustment part 2133. The resolution of the grating ruler can be 0.5µm. By setting the grating ruler, the position of the first adjustment part 2132 and the second adjustment part 2133 can be accurately measured, and in conjunction with the linear drive motor, the adjustment accuracy of the adjustment mechanism 213 can be improved.

[0048] In one embodiment, see Figure 5 The dispensing work group 21 may further include a height measuring unit 214, which is disposed on the drive end of the adjustment mechanism 213, i.e., on the mounting base 2134. Specifically, the height measuring unit 214 can be a laser measuring unit. In this embodiment, by providing a height measuring unit 214 on the drive end of the adjustment mechanism 213, the relative height between the dispensing valve 211 and the product can be measured, making the height adjustment of the dispensing valve 211 more precise. This, in turn, improves the dispensing accuracy of the dispensing work group 21.

[0049] In one embodiment, see Figure 6The product conveying device 3 includes a transport slide 31, a conveying component 32, a positioning mechanism 33, and a product fixture 34. The transport slide 31 is disposed on the worktable 1. The conveying component 32 is disposed inside the transport slide 31 and is used to drive the product to move along the transport slide 31. The product fixture 34 is disposed above the transport slide 31 and is located at the dispensing position. The product fixture 34 is used to position the product. The positioning mechanism 33 is disposed on the transport slide 31 and is used to push the product into the product fixture 34.

[0050] Specifically, the transport chute 31 refers to a chute structure of a certain length, for example, it can be formed by setting two spaced-apart plates, with the transport chute 31 formed between the two plates. The conveying assembly 32 refers to a component or assembly that can transport objects. The conveying assembly 32 can be two conveyor belt assemblies, which are respectively set on the two side walls of the transport chute 31. The product fixture 34 refers to a component that can position the product, and the product fixture 34 is provided with a positioning structure that matches the shape of the product. The positioning mechanism 33 refers to a component or assembly that can push an object to a designated position.

[0051] In this embodiment, the movement direction of the product can be limited by the transport slide 31, and a conveying component 32 is provided within the transport slide 31 to drive the product along the transport slide 31. Simultaneously, a product fixture 34 is provided at the dispensing position. When the product moves to a designated position, a positioning mechanism 33 pushes the product into the product fixture 34, thereby positioning the product more accurately and improving the dispensing precision.

[0052] In one embodiment, see Figure 6The positioning mechanism 33 includes a lifting component 331 and a side-pushing component 332. The side-pushing component 332 is disposed on the side of the transport slide 31 and is used to push the product under the product fixture 34. The lifting component 331 is located below the product fixture 34 and is used to push the product from below into the interior of the product fixture 34. Specifically, both the lifting component 331 and the side-pushing component 332 are components that can push an object to move in a straight line. In this embodiment, the lifting component 331 is disposed below the product fixture 34, and the side-pushing component 332 is disposed on the side of the transport slide 31. A limiting block that cooperates with the side-pushing component 332 is also disposed on the opposite side of the side-pushing component 332. When the product moves to the bottom of the product fixture 34, the side-pushing component 332 can first push the product towards the limiting block, and the product is matched with the position of the product fixture 34 in the horizontal direction through cooperation with the limiting block. Then, the lifting assembly 331 can drive the product vertically into the product fixture 34. The positioning mechanism 33 makes it easier for the product to enter and be fixed in the product fixture 34.

[0053] In an optional embodiment, please refer to Figure 6 The lifting assembly 331 includes a lifting cylinder and a lifting plate. The lifting plate is connected to the drive end of the lifting cylinder, and the lifting cylinder can drive the lifting plate to move in the vertical direction. The side-pushing assembly 332 includes a side-pushing cylinder and a side-pushing block. The side-pushing block is connected to the drive end of the side-pushing cylinder, and the side-pushing cylinder can drive the side-pushing block to move in a second direction.

[0054] In one embodiment, see Figure 6 The product conveying device 3 also includes a waiting-to-be-blocked assembly 35 and a preheating assembly 36. The conveying slide 31 has a preheating position. The waiting-to-be-blocked assembly 35 is used to block the product at the preheating position, and the preheating assembly 36 is used to preheat the product. Specifically, the waiting-to-be-blocked assembly 35 refers to a component or assembly that can block the product from moving along the conveying slide 31. The waiting-to-be-blocked assembly 35 has a first state and a second state. When the waiting-to-be-blocked assembly 35 is in the first state, at least a portion of the waiting-to-be-blocked assembly 35 can block the path of the product's movement. When the waiting-to-be-blocked assembly 35 is in the second state, the waiting-to-be-blocked assembly 35 avoids the path of the product's movement. The preheating assembly 36 refers to a component or assembly that can heat an object. The preheating assembly 36 can heat the product by electric heating. In this embodiment, before dispensing the product, the waiting blocking component 35 can block the product's movement path, causing the product to stop at a position that matches the preheating component 36. Then, the preheating component 36 can heat the product, making the dispensing operation more convenient.

[0055] In an optional embodiment, please refer to Figure 6 The material blocking assembly 35 includes a blocking post and a blocking cylinder. The blocking post is located on the drive end of the blocking cylinder, which can drive the blocking post away from or towards the path of the product movement. This makes the material blocking assembly 35 easier to use.

[0056] In one embodiment, see Figure 1 and Figure 2 The dispensing equipment also includes a loading device 4 and a unloading device 5, both installed on the workbench 1 and located at opposite ends of the product conveying device 3 in the transport direction. Specifically, the loading device 4 is a device capable of accommodating multiple products and continuously placing them onto the product conveying device 3. The unloading device 5 is a device capable of accommodating multiple products after dispensing. In this embodiment, by providing the loading device 4 and unloading device 5 on the workbench 1, and positioning them at opposite ends of the product conveying device 3 in the transport direction, the loading device 4 can continuously place products onto the product conveying device 3, and the unloading device 5 can accommodate the dispensed products, thereby improving the overall automation level of the dispensing equipment and increasing its working efficiency.

[0057] In one embodiment, see Figure 7 The feeding device 4 includes a feeding bracket 41, a feeding bin 42, and a discharging component 43. The feeding bracket 41 is located on the side of the workbench 1. Multiple feeding bins 42 are slidably mounted on the feeding bracket 41. The feeding bins 42 are used to hold products, and the discharging component 43 is used to sequentially eject products from the feeding bins 42. Specifically, the feeding bracket 41 is a support component with a certain height, and can be a columnar structure arranged vertically. The feeding bin 42 is a component with a certain holding space, and multiple placement structures for placing products are also provided within the feeding bin 42. The feeding bin 42 can be slidably mounted on the feeding bracket 41 via a sliding structure, and a drive unit for driving the movement of the feeding bin 42 is also provided on the feeding bracket 41. The drive unit can be an electric push rod, etc. The discharge assembly 43 refers to the component that can push the product out of the feeding bin 42. The discharge assembly 43 may include a discharge component and a discharge drive unit, which drives the discharge component to reciprocate. In this embodiment, during the feeding operation, the feeding bin 42 can be moved to a feeding position that matches the product conveying device 3. Then, the discharge assembly 43 pushes the products in the feeding bin 42 onto the product conveying device 3 in sequence. After the products in the feeding bin 42 are fed, the feeding bin 42 moves away from the feeding position, and the next feeding bin 42 filled with products moves back to the feeding position for feeding. This enables continuous feeding operations and makes the feeding operation of the dispensing equipment more convenient.

[0058] In one embodiment, see Figure 8 The feeding device 5 includes a feeding support 51, a feeding bin 52, and a blocking assembly 53. The feeding support 51 is located on the side of the workbench 1. Multiple feeding bins 52 are slidably mounted on the feeding support 51. The feeding bins 52 are used to hold products, and the blocking assembly 53 is used to block products to prevent them from falling out of the feeding bins 52. Specifically, the feeding support 51 is a support component with a certain height, and can be a columnar structure arranged vertically. The feeding bin 52 is a component with a certain holding space, and multiple placement structures for placing products are also provided within the feeding bin 52. The feeding bin 52 can be slidably mounted on the feeding support 51 via a sliding structure, and a drive unit for driving the movement of the feeding bin 52 is also provided on the feeding support 51. The drive unit can be an electric push rod, etc. The blocking assembly 53 is a component or assembly that can block products; the blocking assembly 53 can be a blocking plate or a blocking rod, etc. In this embodiment, after the product is dispensing, the unloading bin 52 can be moved to the unloading position that matches the product conveying device 3. Furthermore, an unloading mechanism can be provided at the discharge end of the product conveying device 3. The unloading mechanism moves the product from the product conveying device 3 to the unloading bin 52. After one unloading bin 52 is filled with product and moves away from the unloading position, the next empty unloading bin 52 moves back to the unloading position, making the product unloading operation more intelligent and convenient.

[0059] In one embodiment, see Figure 9 The dispensing equipment also includes a dispensing auxiliary device 6, which includes an auxiliary support 61 mounted on the workbench 1.
