Description

Technical Field

[0001] This utility model relates to the field of liquid dispensing technology, and in particular to an environmentally friendly PCB chemical reagent dispenser. Background Technology

[0002] In the production and experimentation of printed circuit boards (PCBs), it is often necessary to accurately dispense various reagents and solutions. Existing technologies have developed automated or semi-automated dispensing equipment that uses pumps, pipelines, and moving mechanisms to quantitatively inject solutions into test tubes. However, these dispensing devices still have significant limitations in practical applications. On the one hand, for ease of batch operations, test tubes are usually placed in test tube racks for overall handling and positioning. On the other hand, in actual production or experimental scenarios, there are situations where test tube racks are not needed, and loose test tubes can be dispensed directly. In this case, the equipment itself needs to have reliable support and positioning capabilities for the test tubes. The common solution is to install a fixed support structure on the equipment to support test tubes when there is no test tube rack. However, this structure interferes with the test tube rack, preventing the rack from being inserted and making it difficult to accommodate both usage scenarios. While a detachable support structure can avoid interference, it requires disassembly and reassembly each time the usage mode is switched, significantly increasing operational complexity and reducing work efficiency. Utility Model Content

[0003] To overcome the shortcomings of existing dispensing equipment, which cannot accommodate both use scenarios with and without test tube racks, and whose fixed support structure interferes with the test tube rack, while detachable support structures avoid interference but require repeated assembly and disassembly when switching modes, seriously affecting work efficiency, this utility model provides an environmentally friendly PCB medicine and reagent dispenser.

[0004] The technical implementation scheme of this utility model is as follows: an environmentally friendly PCB reagent dispenser, including a dispenser, tubing, and a limiting frame; several tubing are connected to the dispenser, and the several tubing are connected to an external water pump; the dispenser is provided with a limiting frame; it also includes a sliding rod, a support plate, a fixing rod, and a moving component; the moving component is connected to the dispenser; the sliding rod is installed on the moving component; the sliding rod is fixedly connected to several tubing; several fixing rods are fixedly connected to the limiting frame; the several fixing rods are slidably connected to a support plate that is compatible with both test tube racks and non-test tube racks; several holes are opened on the support plate; magnets are embedded at the four corners of the support plate, and the top of each fixing rod is made of magnetic metal.

[0005] Optionally, the moving component includes an electric slider and a slide rail; the slide rail is fixedly connected to the dispenser; the electric slider is slidably connected to the slide rail; and the electric slider is fixedly connected to the slide rod.

[0006] Optionally, it also includes rubber rings; a rubber ring adapted to test tubes of different diameters is fixedly attached to each hole in the support plate; and a round hole is provided in the middle of each rubber ring.

[0007] Optionally, the support plate can be detachably connected to the adjacent fixing rod.

[0008] Optionally, a handle is provided on the support plate.

[0009] Optionally, it also includes a carrier plate; the carrier plate is fixed to the dispenser and is located directly below the support plate; the carrier plate has several slots to prevent the test tubes from tilting; each slot is set in an inverted cone shape and each slot is vertically aligned with the hole on the support plate.

[0010] Compared with the prior art, the present invention has the following advantages: by pulling the support plate upward to support and separate the test tubes with the dispensing device, compatibility and adaptation with and without test tube racks can be easily achieved, thereby significantly improving the convenience of equipment use and work efficiency.

[0011] By using rubber rings to adapt to test tubes of different diameters, the equipment effectively avoids tilting and shaking of the test tubes, thus improving its self-adaptability.

[0012] The grooves wrap around and limit the bottom of the test tube, keeping it stable and preventing it from tilting due to uneven force, thus improving the stability of the equipment during use. Attached Figure Description

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1: As Figures 1-4 As shown, an environmentally friendly PCB chemical reagent dispenser includes a dispenser 1, hoses 3, and a limiting frame 4; several hoses 3 are connected to the dispenser 1, and the several hoses 3 are connected to an external water pump; the dispenser 1 is provided with a limiting frame 4.

[0022] It also includes a slide rod 2, a support plate 5, a fixing rod 6, and a moving component; the moving component is connected to the dispensing device 1; the slide rod 2 is installed on the moving component; the slide rod 2 is fixedly connected to several hoses 3; four fixing rods 6 are fixedly connected to the limiting frame 4; the support plate 5 is slidably connected to several fixing rods 6; several holes are opened on the support plate 5; magnets are embedded at the four corners of the support plate 5, and the top of each fixing rod 6 is made of magnetic metal.

[0023] The moving component includes an electric slider 101 and a slide rail 102; the slide rail 102 is fixedly connected to the dispenser 1; the electric slider 101 is slidably connected to the slide rail 102; the electric slider 101 is fixedly connected to the slide rod 2.

[0024] It also includes a rubber ring 103; a rubber ring 103 is fixedly connected to each hole on the support plate 5; and a round hole is provided in the middle of each rubber ring 103.

[0025] Furthermore, the support plate 5 is detachably connected to the adjacent fixing rod 6.

[0026] Furthermore, a handle is provided on the support plate 5.

[0027] Before dispensing liquid into test tubes using dispenser 1, considering the large number of test tubes to be dispensed, workers usually place the test tubes along with the test tube rack into the limiting frame 4. Then, the electric slider 101 is started to move forward precisely along the slide rail 102, thereby driving the slide rod 2 and the hose 3 to be positioned directly above the mouth of each test tube. Then, the external water pump is started to pump the liquid into the hose 3 in a metered amount, and then precisely inject it into the test tube through the hose 3. This process is repeated until all test tubes in the test tube rack are filled with the same amount of liquid. It is worth noting that in the above process, if the test tubes are not placed in the test tube rack, i.e., the worker needs to rely on the dispensing device 1 itself to support the test tubes, a corresponding support structure is required on the dispensing device 1. However, when dispensing test tubes already placed in the test tube rack, this support structure will prevent the test tube rack and the test tubes it carries from being properly placed into the limiting frame 4. While designing the support structure on the dispensing device 1 to be detachable would solve the interference problem, it would make the process of placing the test tubes more cumbersome for the worker. Therefore, when it is necessary to rely on the dispensing device 1 to support the test tubes, the worker can pull... The movable support plate 5 moves upward until its upper side contacts the top of the fixed rod 6. Since magnets are embedded in the four corners of the support plate 5 and the top of the fixed rod 6 is made of magnetic metal, the support plate 5 is attracted to the top of the fixed rod 6. At this time, the worker can pass the test tubes through the holes on the support plate 5 and support the bottom of the test tubes with the dispensing device 1 until all the holes on the support plate 5 are filled with test tubes. By pulling the support plate 5 upward, the system can easily adapt to both scenarios with and without a test tube rack, thereby significantly improving the convenience and efficiency of the equipment. Furthermore, by setting a handle on the support plate 5, the worker can easily pull the support plate 5 upward or reset it.

[0028] Furthermore, when using the holes on the support plate 5 to separate the test tubes, considering the differences in diameter between different test tubes, a rubber ring 103 is set in each hole, and the initial circular hole of the rubber ring 103 matches the smallest diameter of the test tube that the dispenser 1 can dispense. When the smallest diameter test tube is placed, the test tube can pass smoothly through the circular hole and be effectively held by the rubber ring 103, thereby preventing the test tube from tilting or shaking. When the dispenser 1 can dispense the largest diameter test tube, the rubber ring 103 is squeezed by the outer wall of the test tube, and its circular hole expands and tightly covers the surface of the test tube, which can also achieve stable positioning of the large diameter test tube, effectively preventing it from tilting or shaking, and improving the self-adaptive ability of the equipment.

[0029] Furthermore, since the support plate 5 is detachably connected to the fixing rod 6, the support plate 5 can be removed and thoroughly cleaned after multiple uses, thereby effectively preventing residual stains on the surface of the support plate 5 from contaminating the test tube.

[0030] Example 2: Based on Example 1, such as Figure 1 , Figure 5 and Figure 6As shown, it also includes a carrier plate 201; the carrier plate 201 is fixedly connected to the dispensing device 1, and the carrier plate 201 is located directly below the support plate 5; the carrier plate 201 has a number of slots 20101; each slot 20101 is set in an inverted cone shape, and each slot 20101 is directly opposite the hole on the support plate 5.

[0031] In the process of using the rubber ring 103 to adapt to test tubes of different diameters and prevent them from tilting, since the rubber ring 103 itself is easily deformable and the bottom of the test tube lacks effective wrapping and restraint, it is still difficult for workers to completely avoid the test tube tilting to one side due to uneven force caused by squeezing the rubber ring 103 after placing the test tube. To this end, a support plate 201 is set on the dispensing device 1 to support the bottom of the test tube. At the same time, since each slot 20101 is aligned vertically with the hole on the support plate 5, after the worker passes the test tube through the rubber ring 103, its bottom can be accurately placed into the corresponding slot 20101. With the wrapping and restraint effect of the slot 20101 on the bottom of the test tube, the test tube can be kept stable and is not easy to tilt due to uneven force, thus improving the stability of the equipment during use. Furthermore, each slot 20101 is set in an inverted cone shape to adapt to the bottom of test tubes of different diameters.
