Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to a dispensing device for disassembling a glue cartridge. Background Technology

[0002] A dispensing machine is used to precisely apply, inject, coat, or drip adhesive or other fluids to specific locations on a product, typically an electronic component such as a PCB board. A dispensing machine generally includes a mounting frame and a dispensing pressure cylinder containing the adhesive. The dispensing pressure cylinder is mounted on the mounting frame, and the adhesive flows out from the cylinder, thus completing the dispensing process on the product.

[0003] When the glue in the existing dispensing cartridge is used up, it needs to be replaced. Since the entire cartridge is fixed to the mounting plate by bolts, multiple bolts need to be removed and installed, which takes a long time and is quite troublesome. At the same time, the machine needs to be stopped when replacing it. The replacement method in the existing technology reduces production efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a glue supply device that is easy to disassemble, making it convenient to replace without complicated operations and reducing downtime.

[0014] Furthermore, anti-rotation surfaces are provided on both sides of the outlet component, a baffle is provided at the bottom of the anti-rotation surface, and a stop block is provided at the top of the outlet component, allowing the outlet component to move up and down.

[0015] The advantage of adopting the above technical solution is that, since the bottom of the rubber tube is connected to the outlet part by a thread, the outlet part can be prevented from rotating when the rubber tube is disassembled due to the anti-rotation surface, which facilitates the disassembly of the rubber tube.

[0016] Furthermore, the liquid level sensing component includes a sensor and a magnet, a piston is disposed inside the rubber tube, the magnet is placed on the piston, and the sensor is located on the bottom side of the outer cylinder.

[0017] The advantage of adopting the above technical solution is that, as the glue is dispensed, the magnet follows the piston down. When it reaches the set position, the sensor detects the magnet and reminds the staff to replace the glue cartridge as soon as possible.

[0018] Furthermore, the outer cylinder is provided with a mounting plate, which includes a first clamping plate and a second clamping plate, and the first clamping plate and the second clamping plate clamp and fix the outer cylinder.

[0019] The advantage of adopting the above technical solution is that the mounting plate is used to fix the outer cylinder and fix the outer cylinder to the dispensing equipment.

[0020] Furthermore, an observation hole is provided on the side of the outer cylinder.

[0021] The advantage of adopting the above technical solution is that the observation hole allows for a direct view of the state inside the glue tube and the remaining amount of glue.

[0022] Furthermore, a sealing plate is provided at the bottom of the outer cylinder.

[0023] Furthermore, the sealing ring is provided with a support portion, and the outer side of the support portion is provided with an inwardly tapering edge, which contacts the upper side of the rubber tube.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] like Figure 1-3 As shown, this utility model discloses a glue supply device that facilitates the disassembly of a glue cartridge, comprising:

[0034] The outer cylinder 1 has an internal cavity for accommodating the rubber tube 2. An upper cover 3 is installed on the upper side of the outer cylinder 1, and the upper cover 3 is fixed by a protruding block 11 on the side of the outer cylinder 1.

[0035] An outlet component includes an outlet part 4 and a glue outlet 5. The glue outlet 5 is located at the bottom of the outlet part 4. The upper end of the outlet part 4 extends from the lower side into the interior of the outer cylinder 1 and is detachably connected to the glue cylinder 2. The glue outlet 5 is locked to the bottom of the outlet part 4.

[0036] Liquid level sensing component, used to sense the remaining amount inside the rubber tube 2.

[0037] The advantages of adopting the above technical solution are that the top cover 3 can be disassembled and installed with just a rotation, making it convenient to replace the glue cylinder 2. At the same time, the liquid level sensing component is set to sense the position of the glue, eliminating the need for complicated operations, reducing downtime, and greatly improving production efficiency.

[0038] In some implementations, a fixing part 31 is provided on the side of the top cover 3. The fixing part 31 is provided with a fixing groove 32 and a withdrawal groove 33. The withdrawal groove 33 communicates with the fixing groove 32 and is vertically arranged. The fixing part and the fixing groove are centrally symmetrical on the top cover, and the protruding blocks are symmetrically arranged. During installation, the protruding blocks 11 are fixed in the fixing groove 32. At the same time, the fixing groove 32 is provided with an arc-shaped recess that cooperates with the protruding blocks 11, so that the protruding blocks 11 will not move after entering the arc-shaped recess and being fixed. Vertical stripes are provided on the upper side of the fixing part 31 to increase friction and facilitate the rotation of the top cover 3 for easy disassembly.

[0039] Furthermore, the top of the cover 3 is provided with an air inlet 34, which is connected to an air inlet pipe. The inside of the cover 3 is provided with a sealing ring 6, which has an air inlet channel 63. The sealing ring 6 is fixedly installed on the upper wall of the cover 3.

[0040] The air inlet 34 is used to introduce gas so that the glue in the glue cylinder 2 can be driven by air pressure to flow out from the glue outlet 5. The sealing ring 6 is set to seal the gas used for driving, so as not to leak and to ensure uniform glue dispensing.

[0041] Furthermore, the sealing ring 6 is provided with a support portion 61, an air inlet channel 63 in the middle of the support portion 61, and an inwardly contracting edge 62 on the outer side of the support portion 61. During installation, the edge 62 enters the inner side of the rubber sleeve 2 and contacts the upper edge of the rubber sleeve 2. High-pressure gas is introduced, causing the edge 62 to be squeezed outward, pressing the sealing ring 6 tightly against the upper edge 62 of the rubber sleeve 2, thus achieving a seal. The sealing ring 6 serves a sealing function, and the inwardly contracting edge 62 can make good contact with the upper edge of the rubber sleeve 2, maintaining good sealing performance even when high-pressure gas is introduced.

[0042] In some implementations, anti-rotation surfaces 41 are provided on both sides of the outlet component 4 (e.g., Figure 4 As shown), a baffle 42 is provided at the bottom of the anti-rotation surface 41. The baffle 42 is attached to the bottom of the outlet part 4 by screws. A stop block 43 is provided at the top of the outlet part 4, allowing the outlet part 4 to move up and down. A sealing plate 13 is attached to the bottom of the outer cylinder 1. The sealing plate 13 has a receiving hole for accommodating the outlet part 4. During the up and down movement, the movement position of the outlet part 4 is restricted by the baffles 42 and the stop blocks 43 at both ends. Figure 1This is the installation state of the outlet component 4. At this time, the outlet component extends from the bottom of the outer cylinder 1. The outlet component 4 has a threaded hole inside. The bottom of the rubber tube 2 has a fixing head with external threads that connect to the outlet component 4. During installation, the outlet component 4 is in the extended state. When it is necessary to disassemble the rubber tube 2, simply remove the top cover 3 and then move the outlet component 4 upwards. The upper end of the rubber tube 2 extends from the upper side of the outer cylinder 1. Figure 2 As shown, disassembly can be completed by rotation. At the same time, the outlet part 4 is provided with an anti-rotation surface 41, so the outlet part 4 will not rotate, which facilitates the disassembly of the rubber tube 2.

[0043] In some implementations, the liquid level sensing component includes a sensor 7 and a magnet 8. A piston 21 is provided inside the glue tube 2, and the magnet 8 is placed on the piston 21. The sensor 7 is fixed to the bottom side of the outer cylinder 1. The sensor 7 can be a Hall sensor. As the glue is dispensed, the magnet 8 descends with the piston 21. When the glue tube 2 is emptied, the Hall sensor can sense the position of the magnet 8, trigger the internal circuit, connect to the control system, trigger an alarm signal, and remind the operator to replace the glue in time.

[0044] Furthermore, the outer cylinder 1 is provided with a mounting plate 9, which includes a first clamping plate 91 and a second clamping plate 92. The first clamping plate 91 and the second clamping plate 92 clamp and fix the outer cylinder 1. The two clamping plates are fastened by screws to fix the outer cylinder 1 to the dispensing equipment.

[0045] Furthermore, an observation hole 12 is provided on the side of the outer cylinder 1. The number of observation holes 12 can be 2-5, depending on the needs. They are vertically set on the side of the outer cylinder 1. The observation holes 12 allow for a direct view of the state inside the glue tube 2 and the remaining amount of glue.

[0046] During the installation of the glue cartridge 2, first remove the top cover 3, place the glue cartridge 2 filled with glue into the outer cylinder 1, place the magnet 8 on the upper side of the piston 21 of the glue cartridge 2, then close the top cover 3, introduce gas, and the piston 21 is pushed downward under the gas drive, and glue is discharged from the glue outlet 5. When the piston 21 reaches the set position at the bottom of the glue cartridge 2, the sensor 7 senses the position of the magnet 8 and issues an alarm to remind the operator to replace it.

[0047] To replace glue cartridge 2, rotate the top cover 3 until the protruding block 11 is positioned above the vertical groove. Then, lift it upwards to remove the top cover 3. Next, push the outlet part 4 upwards. At this point, glue cartridge 2 will protrude from the top of the outer cylinder 1. Rotate glue cartridge 2 to remove it. Then, insert a new glue cartridge 2 to complete the replacement. This eliminates the hassle of traditional threaded locking methods, allowing operators to replace glue without using any tools, greatly improving work efficiency.

[0048] This application has the following advantages:

[0049] 1. Prevent glue leakage;

[0050] 2. Sensor 7 works in conjunction with magnet 8 to monitor the glue level and remind operators to replace it in time;

[0051] 3. The top cover features a 3-snap-on design, which reduces the complexity and time consumption of manual operation, minimizes downtime, and improves production efficiency.

[0052] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
