Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automated machinery technology, and more specifically, it relates to a dispensing structure of a dispensing device. Background Technology
[0002] When applying adhesive to the surface of a product, a dispensing device is required. The product is placed on the device, and the dispensing structure on the device is located on the top of the product. The dispensing structure moves to the product position, and the dispensing valve on the dispensing structure dispenses the adhesive, accurately applying it to the product, thereby completing the product processing.
[0003] According to CN202121757565.6, this application provides a dispensing valve, including a base; a dispensing needle mounted on one end of the base; a dispensing syringe with one end connected to the feed end of the dispensing needle; and an air supply unit mounted on the other end of the base, with the air outlet connected to the other end of the dispensing syringe. The air supply unit supplies air to the dispensing syringe to expel liquid from the dispensing needle. This application uses the air supply unit to supply air to the dispensing syringe, and the pressure is used to discharge the liquid from the dispensing syringe through the dispensing needle. This application uses pneumatic extrusion of liquid instead of traditional mechanical extrusion methods such as screw valves and plunger valves, thereby avoiding the rigid squeezing effect of screw valves and plunger valves on the liquid and preventing damage to the internal structure of the liquid. Especially for liquids with particulate composition such as solder paste and silver paste, it is less likely to cause the particles to deform or stick together to form large particles, thus avoiding problems such as needle blockage or unstable outlet flow.
[0004] Based on the above, the dispensing valve on the existing dispensing structure is generally installed using a multi-set bolt structure. In order to ensure the service life of the dispensing valve, it is necessary to disassemble the dispensing valve regularly for deep cleaning. When disassembling and installing the dispensing valve, the staff needs to disassemble and install multiple sets of bolts one by one, which is a rather cumbersome operation. Utility Model Content

This addresses the issue that the dispensing valve in the existing dispensing structure is generally installed using multiple sets of bolts. In order to ensure the service life of the dispensing valve, it is necessary to disassemble the dispensing valve periodically for deep cleaning. When disassembling and installing the dispensing valve, the operator needs to disassemble and install multiple sets of bolts one by one, which is a rather cumbersome operation.
[0006] The purpose and function of the dispensing structure of the dispensing device of this utility model are achieved by the following specific technical means:
[0007] A dispensing structure for a dispensing device includes a dispensing body, a dispensing robotic arm, a dispensing bracket, mounting holes, a dispensing valve body, a limiting block, a valve body mounting mechanism, and a movement limiting mechanism. The dispensing robotic arm is slidably connected to the upper side of the dispensing body.

The movement limiting mechanism is located inside the lower end face of the dispensing bracket.
[0008] Furthermore, the valve body mounting mechanism includes: a limiting rubber ring and a bottom support rubber ring; the limiting rubber ring is fixedly connected to the upper inner end face of the dispensing bracket, the limiting rubber ring is located inside the upper mounting hole, the limiting rubber ring is located on the upper side of the outer end face of the dispensing valve body, and the limiting rubber ring is a silicone ring structure; the bottom support rubber ring is fixedly connected to the lower inner end face of the dispensing bracket, the bottom support rubber ring is located inside the lower mounting hole, the bottom support rubber ring is located on the lower side of the outer end face of the dispensing valve body, and the bottom support rubber ring is a silicone ring structure.
[0009] Furthermore, the valve body mounting mechanism also includes: a limiting screw and a limiting knob; the limiting screw is rotatably connected to the middle position inside the front end face of the dispensing bracket; the limiting knob is coaxially fixedly connected to the front end face of the limiting screw, and the limiting knob rotates to the middle position of the front end face of the dispensing bracket.
[0010] Furthermore, the valve body mounting mechanism also includes: a limiting slider and a limiting screw hole; the limiting slider is slidably connected to the front side inside the dispensing bracket, and the limiting pressure block is slidably connected to the rear end face of the limiting slider; the limiting screw hole is opened in the middle position inside the front end face of the limiting slider, and the limiting screw hole is threadedly connected to the limiting lead screw.
[0011] Furthermore, the valve body mounting mechanism also includes: a limiting socket, a limiting spring, and a limiting pin; the limiting socket is located at the middle of the front end face of the dispensing valve body; the limiting spring is fixedly connected inside the limiting slider; the limiting pin is fixedly connected at the middle of the rear end face of the limiting pressure block, and the limiting pin is inserted into the limiting socket.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This utility model employs a valve body mounting mechanism, which allows the dispensing valve body to be placed inside the mounting hole when installed on the equipment. Then, turning the limiting knob rotates the limiting pressure block to squeeze the dispensing valve body, thereby inserting the limiting pin into the limiting hole and fixing the dispensing valve body to the dispensing bracket. This avoids the need for workers to find tools and tighten bolts one by one for installation, saving workers installation steps and facilitating the maintenance of the dispensing valve body.
[0015] This invention employs a movement restriction mechanism to simultaneously move the dispensing valve body downwards along with the blocking slide bar. When the dispensing valve body is close to the product, the blocking slide bar contacts the product first, prompting the operator to adjust the distance between the dispensing valve body and the product in a timely manner to avoid affecting the dispensing of glue from the dispensing valve body and making it convenient for operators to use the dispensing equipment.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0026] Example 1:
[0027] As attached Figure 1 To be continued Figure 6 As shown:
[0028] This utility model provides a dispensing structure for a dispensing device, including a dispensing body 1, a dispensing robotic arm 2, a dispensing bracket 3, mounting holes 301, a dispensing valve body 4, a limiting pressure block 10, and a valve body mounting mechanism. The dispensing robotic arm 2 is slidably connected to the upper side of the dispensing body 1. The dispensing bracket 3 is fixedly connected to the lower side of the front end face of the dispensing robotic arm 2. Two sets of mounting holes 301 are provided, which are respectively opened on the upper and lower sides of the dispensing bracket 3. Both sets of mounting holes 301 are circular holes. The dispensing valve body 4 is located on the inner end face of the dispensing bracket 3 and is inserted into the two sets of mounting holes 301. The limiting pressure block 10 is slidably connected inside the dispensing bracket 3. The valve body mounting mechanism is located inside the dispensing bracket 3.
[0029] The valve body mounting mechanism includes a limiting rubber ring 5 and a bottom support rubber ring 6. The limiting rubber ring 5 is fixedly connected to the inner end face of the upper side of the dispensing bracket 3, and is located inside the upper mounting hole 301 and above the outer end face of the dispensing valve body 4. The limiting rubber ring 5 is a silicone ring structure. The bottom support rubber ring 6 is fixedly connected to the inner end face of the lower side of the dispensing bracket 3, and is located inside the lower mounting hole 301 and below the outer end face of the dispensing valve body 4. The bottom support rubber ring 6 is a silicone ring structure. During use, when the dispensing valve body 4 is inserted into the inner end face of the dispensing bracket 3, the limiting rubber ring 5 and the bottom support rubber ring 6 increase the friction of the dispensing valve body 4 and protect the dispensing valve body 4.
[0030] The valve body mounting mechanism also includes: a limiting screw 7 and a limiting knob 8; the limiting screw 7 is rotatably connected to the middle position inside the front end face of the dispensing bracket 3; the limiting knob 8 is coaxially fixedly connected to the front end face of the limiting screw 7, and the limiting knob 8 rotates to the middle position of the front end face of the dispensing bracket 3. During use, the operator twists the limiting knob 8 to rotate, and the rotation of the limiting knob 8 drives the limiting screw 7 to rotate.
[0031] The valve body mounting mechanism also includes: a limiting slider 9 and a limiting screw hole 901; the limiting slider 9 is slidably connected to the front side inside the dispensing bracket 3, and the limiting pressure block 10 is slidably connected to the interior of the rear end face of the limiting slider 9; the limiting screw hole 901 is opened in the middle position inside the front end face of the limiting slider 9, and the limiting screw hole 901 is threadedly connected to the limiting screw 7. During use, when the limiting screw 7 rotates inside the limiting screw hole 901, it drives the limiting slider 9 to slide, and the sliding of the limiting slider 9 drives the limiting pressure block 10 to slide.
[0032] The valve body mounting mechanism also includes: a limiting hole 401, a limiting spring 1001, and a limiting pin 1002; the limiting hole 401 is located at the middle of the front end face of the dispensing valve body 4; the limiting spring 1001 is fixedly connected inside the limiting slider 9; the limiting pin 1002 is fixedly connected at the middle of the rear end face of the limiting pressure block 10, and the limiting pin 1002 is inserted into the limiting hole 401. During use, the limiting pressure block 10 slides, causing the limiting pin 1002 to slide, and the limiting pin 1002 slides into the limiting hole 401. At the same time, when the limiting pressure block 10 squeezes the dispensing valve body 4, the limiting spring 1001 is compressed, thereby stably installing the dispensing valve body 4 inside the dispensing bracket 3, ensuring that the dispensing bracket 3 drives the dispensing valve body 4 to move and dispense glue, and facilitating the disassembly and installation of the dispensing valve body 4, and facilitating the maintenance of the dispensing valve body 4 in the future.
[0033] The specific usage and function of this first embodiment are as follows:
[0034] During use, when the dispensing valve body 4 is inserted into the inner end face of the dispensing bracket 3, the limiting rubber ring 5 and the bottom support rubber ring 6 increase the friction of the dispensing valve body 4 and protect it. The operator turns the limiting knob 8, which drives the limiting screw 7 to rotate. When the limiting screw 7 rotates inside the limiting screw hole 901, it drives the limiting slider 9 to slide. The sliding of the limiting slider 9 drives the limiting pressure block 10 to slide. The sliding of the limiting pressure block 10 drives the limiting pin 1002 to slide. The limiting pin 1002 slides into the limiting insertion hole 401. At the same time, when the limiting pressure block 10 squeezes the dispensing valve body 4, the limiting spring 1001 is compressed, thereby stably installing the dispensing valve body 4 inside the dispensing bracket 3. This ensures that the dispensing bracket 3 drives the dispensing valve body 4 to move and dispense glue, while also facilitating the disassembly and installation of the dispensing valve body 4 and making it easier to maintain it later.

The upper side of the blocking slide rod 11 is slidably connected to the lower end face of the dispensing bracket 3, and the lower side of the blocking slide rod 11 slides on the lower side of the dispensing bracket 3. The blocking spring 1101 is fixedly connected to the lower side inside the dispensing bracket 3, and the upper end face of the blocking slide rod 11 and the blocking spring 1101 are elastically connected. The blocking ball 1102 is movably connected to the lower end face of the blocking slide rod 11. During use, the dispensing bracket 3 slides, causing the blocking slide rod 11 to slide. When the dispensing bracket 3 moves downwards to a lower position, it causes the blocking slide rod 11 and the blocking ball 1102 to move downwards and fit against the dispensing body 1, indicating to the operator that the dispensing valve body 4 is about to touch the workpiece.
[0038] The specific usage and function of this second embodiment are as follows:
[0039] During use, the dispensing bracket 3 slides, causing the blocking slide bar 11 to slide. When the dispensing bracket 3 moves downwards, it causes the blocking slide bar 11 and the blocking ball 1102 to move downwards and fit against the dispensing body 1, indicating to the personnel that the dispensing valve body 4 is about to touch the workpiece, thus avoiding the problem of the dispensing valve body 4 being damaged due to impacts to the nozzle.
