[0001] This utility model relates to the field of jewelry processing equipment technology, specifically a jewelry hot melt dispensing machine. Background Technology

[0002] In jewelry manufacturing, the dispensing process is a crucial step, commonly used in jewelry setting and accessory connection. It requires precisely applying hot melt adhesive to designated areas to ensure the secure connection and aesthetic appeal of jewelry components. With the development of the jewelry industry, consumers have increasingly higher demands for the craftsmanship and appearance quality of jewelry, and traditional jewelry dispensing methods are gradually becoming insufficient to meet production needs.

[0003] Based on the above, the inventors have discovered the following problems: Although current jewelry hot melt dispensing machines can achieve automated dispensing, they have not been optimized for the characteristics of jewelry, such as small size, delicate structure, and complex dispensing positions, resulting in their flexibility being unable to meet the needs of jewelry processing.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a jewelry hot melt dispensing machine in order to achieve a more practical purpose. Utility Model Content

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A jewelry hot melt dispensing machine includes a dispensing table with connecting seats on both sides of its top. The top of the dispensing table has an X-axis translation mechanism for moving the connecting seats, and the top of the connecting seats has a Y-axis translation mechanism. The moving end of the Y-axis translation mechanism has a pair of movable plates. One side of each movable plate has a dispensing head, and the top of each movable plate has a height adjustment mechanism for adjusting the height of the dispensing head. A frame is located on one side of the dispensing table, and a hot melt adhesive supply assembly is mounted on the top of the frame. A vertical frame is mounted on one side of the frame, and a horizontal arm is rotatably connected to the top of the vertical frame. A hook for suspending a dispensing tube is mounted on one side of the bottom of the horizontal arm, and a tube holder for fixing the dispensing tube is mounted on the top of one side of the vertical frame.

[0008] Furthermore, the X-axis translation mechanism includes a pair of first slide rails, which are respectively located on both sides of the top of the dispensing table. A fixed seat is installed at the bottom of the first slide rail, and the bottom of the fixed seat is fixedly connected to the top of the dispensing table. A first retaining seat is installed at both ends of the first slide rail. A first pulley is rotatably connected to the inner side of the first retaining seat. A first synchronous belt is fitted on the outer side of the pair of first pulleys. A first slider is installed on the outer side of the first synchronous belt. The bottom of the first slider is slidably connected to the top of the first slide rail. The top of the first slider is fixedly connected to the bottom of the connecting seat. A first motor is installed on one side of one of the first retaining seats. The output end of the first motor is connected to one end of one of the first pulleys. A drive shaft is installed on the inner side of the pair of first pulleys.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: the first slide rail of the X-axis translation mechanism is slidably connected to the first slider, guiding the connecting seat to move in a straight line and avoiding lateral offset; the first pulley and the first synchronous belt cooperate to convert the rotational motion of the first motor into linear motion, ensuring stable movement speed; the transmission shaft synchronously rotates a pair of first pulleys, realizing synchronous movement of the connecting seats on both sides; the fixed seat fixes the first slide rail, preventing slide rail displacement, further ensuring lateral movement accuracy, and adapting to the lateral multi-point adhesive requirements of jewelry workpieces.

[0010] Furthermore, the Y-axis translation mechanism includes a crossbar, with its bottom ends fixedly connected to the top ends of a pair of connecting seats on both sides.

A second slider is slidably connected to the outer side of the second slide rail. One side of the second slider is fixedly connected to the bottom end of one end face of the movable plate.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the crossbar of the Y-axis translation mechanism provides a mounting base for the second retainer, ensuring the stable rotation of the second pulley; the second synchronous belt cooperates with the connecting block to drive the movable plate to move longitudinally, adapting to the longitudinal dispensing path of jewelry; the second motor achieves precise longitudinal position control, avoiding dispensing misalignment caused by motor step loss; and the second slide rail and the second slider guide the sliding, reducing the lateral force of the synchronous belt drive, preventing the movable plate from tilting, and ensuring longitudinal dispensing accuracy.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by fixing the pneumatic push rod with the fixed plate of the height adjustment mechanism, the push rod can be stably extended and retracted. The lifting plate at the output end of the pneumatic push rod drives the connecting arm to rise and fall, thereby adjusting the height of the dispensing head to adapt to the dispensing spacing of jewelry of different thicknesses. The lifting plate is guided to move vertically by the sliding cooperation between the third slider and the third slide rail, avoiding the pneumatic push rod from deviating and causing the dispensing head to tilt.

[0014] Furthermore, a column is installed at the top of the dispensing station, and a control console is rotatably connected to the outside of the column.

A second adhesive delivery pipe is installed at the output end of the adhesive quantity control pump. One end of the second adhesive delivery pipe is connected to the input end of the dispensing head.

[0017] The advantages of adopting the above-mentioned further solution are: heating the hot melt adhesive in the electrically heated adhesive canister of the hot melt adhesive supply component avoids poor flowability due to excessively low adhesive temperature or scorching of the adhesive due to excessively high temperature; preventing dust from falling in through the canister lid ensures the cleanliness of the hot melt adhesive; precisely controlling the output of hot melt adhesive through the adhesive quantity control pump in the chassis adapts to the micro-dispensing needs of jewelry; and achieving a stable connection between the adhesive canister and the dispensing head through the first and second adhesive delivery pipes, avoiding adhesive leakage, ensuring continuous adhesive supply, and reducing waste caused by dispensing interruptions.

[0018] Furthermore, each of the four corners of the top of the dispensing station is equipped with a support base and a first universal wheel, and each of the four corners of the bottom of the frame is equipped with a second universal wheel.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, by using the support bases at the four corners of the top of the dispensing table, the friction between the equipment and the ground is increased when the equipment is fixed, preventing the equipment from shifting during dispensing. The first caster wheel and the second caster wheel at the bottom of the frame enable the overall flexible movement of the equipment to adapt to workshop layout adjustments.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This jewelry hot melt dispensing machine provides a stable dispensing platform through the dispensing table, avoiding platform deformation from affecting dispensing accuracy; the X-axis translation mechanism drives the connecting seat to move laterally, and the Y-axis translation mechanism drives the movable plate to adjust longitudinally, achieving precise two-dimensional positioning of the dispensing head; the height adjustment mechanism adjusts the height of the dispensing head to adapt to the dispensing spacing requirements of jewelry of different thicknesses; the hot melt adhesive supply component provides stable hot melt adhesive, avoiding dispensing defects caused by uneven adhesive volume or temperature fluctuations; the horizontal arm and hook of the upright frame suspend the adhesive delivery pipe, and the pipe rack fixes the pipe, preventing the adhesive delivery pipe from tangling or being pulled, thus avoiding affecting dispensing.

First retaining seats 403 are mounted on both ends of each first slide rail 401. A first pulley is rotatably connected to the inner side of each first retaining seat 403. A first synchronous belt 404 is fitted onto the outer side of each pair of first pulleys. A first slider 407 is mounted on the outer side of the first synchronous belt 404. The bottom of the first slider 407 is slidably connected to the top of the first slide rail 401, and the top of the first slider 407 is fixedly connected to the bottom of the connecting seat 5.

The synchronous movement of the pair of first pulleys is achieved by the synchronous rotation of the drive shaft 406, realizing synchronous movement of the connecting seats 5 on both sides. The first slide rail 401 is fixed by the fixed seat 402 to prevent slide rail displacement, further ensuring the accuracy of lateral movement and adapting to the lateral multi-point adhesive requirements of jewelry workpieces.

[0030] The Y-axis translation mechanism 6 includes a crossbar 601. The bottom ends of the crossbar 601 are fixedly connected to the top ends of a pair of connecting seats 5 on both sides.

One end of the connecting block 606 is fixedly connected to the top end of one end face of the movable plate 7. A second synchronous belt 604 is installed on one side of the crossbar 601. The second slide rail 607 has a second slider 608 slidably connected to its outer side.

The crossbar 601 of the Y-axis translation mechanism 6 provides an installation base for the second retaining seat 602, ensuring the stable rotation of the second pulley 603. The second synchronous belt 604 cooperates with the connecting block 606 to drive the movable plate 7 to move longitudinally, adapting to the longitudinal dispensing path of jewelry. The second motor 605 achieves precise longitudinal position control, avoiding dispensing misalignment caused by motor step loss. The sliding guide between the second slide rail 607 and the second slider 608 reduces the lateral force of the synchronous belt drive, prevents the movable plate 7 from tilting, and ensures longitudinal dispensing accuracy.

[0031] The height adjustment mechanism 8 includes a fixed plate 801, a pneumatic push rod 802 mounted on the top of the fixed plate 801, a lifting plate 803 mounted on the output end of the pneumatic push rod 802, a connecting arm 804 mounted on one side of the lifting plate 803, one end of the connecting arm 804 being fixedly connected to one side of the top of the dispensing head 9, and a third slider 805 mounted on the other side of the lifting plate 803, a third slide rail 806 being slidably connected to the inner side of the third slider 805, and one side of the third slide rail 806 being fixedly connected to the other end face of the movable plate 7.

The lifting plate 803 at the output end of the pneumatic push rod 802 drives the connecting arm 804 to rise and fall, thereby adjusting the height of the dispensing head 9 to adapt to the dispensing spacing of jewelry of different thicknesses. The sliding cooperation between the third slider 805 and the third slide rail 806 guides the vertical movement of the lifting plate 803 to prevent the pneumatic push rod 802 from deviating and causing the dispensing head 9 to tilt.

[0032] The dispensing station 1 has a column 10 installed at the top, and a control console 11 is rotatably connected to the outside of the column 10. The control console 11 is supported by the column 10 at the top of the dispensing station 1, so that the operator can operate without bending over, reducing labor intensity. The dispensing parameters can be centrally set through the control console 11.

[0033] The hot melt adhesive supply assembly 14 includes a chassis 1401 and an electrically heated adhesive tank 1402. A can lid 1403 is hinged to the top of the electrically heated adhesive tank 1402. The bottom ends of the chassis 1401 and the electrically heated adhesive tank 1402 are fixedly connected to the top of the frame 12.

The hot melt adhesive is heated by the electrically heated glue tank 1402 of the hot melt adhesive supply component 14 to avoid poor flowability due to excessively low glue temperature or scorching of the glue due to excessively high glue temperature. The can lid 1403 prevents dust from falling in and ensures the cleanliness of the hot melt adhesive. The glue quantity control pump 1404 in the chassis 1401 precisely controls the output of hot melt adhesive to meet the micro-dispensing needs of jewelry. The first glue delivery tube and the second glue delivery tube realize a stable connection between the glue tank and the dispensing head to avoid glue leakage, ensure glue supply continuity, and reduce waste caused by dispensing interruption.

[0034] The dispensing table 1 is equipped with support bases 2 and first casters 3 at the four corners of its top, and the frame 12 is equipped with second casters 13 at the four corners of its bottom. The support bases 2 at the four corners of the top of the dispensing table 1 increase the friction with the ground when the equipment is fixed, preventing the equipment from shifting during dispensing. The first casters 3 and the second casters 13 at the bottom of the frame 12 enable the equipment to move flexibly as a whole to adapt to the adjustment of the workshop layout.

[0035] Specifically, the working principle of this jewelry hot melt dispensing machine is as follows: During use, the dispensing table 1 provides a stable dispensing platform to prevent platform deformation from affecting dispensing accuracy; the X-axis translation mechanism 4 drives the connecting seat 5 to move laterally, and the Y-axis translation mechanism 6 drives the movable plate 7 to adjust longitudinally, achieving precise two-dimensional positioning of the dispensing head 9; the height adjustment mechanism 8 adjusts the height of the dispensing head 9 to adapt to the dispensing spacing requirements of jewelry of different thicknesses; the hot melt adhesive supply component 14 provides stable hot melt adhesive to avoid dispensing defects caused by uneven adhesive quantity or temperature fluctuations; the horizontal arm 16 and hook 17 of the upright frame 15 suspend the adhesive delivery pipe, and the pipe rack 1501 fixes the pipe to prevent the adhesive delivery pipe from tangling or being pulled, thus affecting dispensing. The X-axis translation mechanism 4 guides the connecting seat 5 to move linearly by sliding the first slide rail 401 and the first slider 407, preventing lateral offset. The first pulley and the first synchronous belt 404 convert the rotational motion of the first motor 405 into linear motion, ensuring stable movement speed. The transmission shaft 406 synchronizes the rotation of a pair of first pulleys, enabling synchronous movement of the connecting seats 5 on both sides. The fixed seat 402 fixes the first slide rail 401, preventing slide rail displacement and further ensuring lateral movement accuracy, adapting to the multi-point adhesive requirements of jewelry workpieces. The crossbar 601 of the Y-axis translation mechanism 6 provides the mounting base for the second retaining seat 602, ensuring stable rotation of the second pulley 603. The second synchronous belt 604, in conjunction with the connecting block 606, drives the movable plate 7 to move longitudinally, adapting to the longitudinal dispensing path of the jewelry. The second motor 605 achieves precise longitudinal position control, preventing dispensing misalignment due to motor step loss. The second slide rail 607 and the second slider 608 provide sliding guidance, reducing lateral force from the synchronous belt drive, preventing the movable plate 7 from tilting, and ensuring longitudinal dispensing accuracy. The fixed plate 801 of the height adjustment mechanism 8 fixes the pneumatic push rod 802, ensuring stable extension and retraction. The lifting plate 803 at the output end of the pneumatic push rod 802 drives the connecting arm 804 to rise and fall, thereby adjusting the height of the dispensing head 9 to adapt to the dispensing spacing of jewelry of different thicknesses. The third slider 8... 05 slides in conjunction with the third slide rail 806 to guide the vertical movement of the lifting plate 803, preventing the pneumatic push rod 802 from shifting and causing the dispensing head 9 to tilt. The control console 11 is supported by the column 10 at the top of the dispensing table 1, allowing operators to operate without bending over, reducing labor intensity. The control console 11 enables centralized setting of dispensing parameters. The hot melt adhesive is heated by the electrically heated glue tank 1402 of the hot melt adhesive supply component 14, preventing poor flowability due to excessively low glue temperature or scorching of the adhesive due to excessively high temperature. The can lid 1403 prevents dust from falling in, ensuring the cleanliness of the hot melt adhesive. The glue volume control pump 1404 inside the chassis 1401 precisely controls the output of hot melt adhesive, adapting to the micro-dispensing needs of jewelry.A stable connection between the glue tank and the dispensing head is achieved through the first and second glue delivery pipes, preventing glue leakage, ensuring continuous glue supply, and reducing waste caused by dispensing interruptions. The support seats 2 at the four corners of the top of the dispensing table 1 increase friction with the ground when the equipment is fixed, preventing equipment displacement during dispensing. The first caster wheel 3 and the second caster wheel 13 at the bottom of the frame 12 allow for flexible overall movement of the equipment, adapting to workshop layout adjustments. This invention effectively achieves three-dimensional positioning, ensuring the precision and consistency of jewelry dispensing, meeting the high-quality production requirements of jewelry, and possesses high practical value.
