Description

Technical Field

[0001] The present invention relates to the technical field of glue dispensing equipment, in particular to a glue dispensing jig. Background Art

[0002] Coils are widely used in many electronic devices and applications, primarily for generating magnetic fields, storing electrical energy, or transmitting signals. During the coil production process, glue dispensing is required. This provides a protective layer for the circular coil, preventing it from being corroded by moisture, dust, and chemicals in the environment, thereby extending its service life. Gluing also improves its structural stability, preventing problems such as loosening or falling off under high-frequency vibration or external forces. Currently, manual glue dispensing is typically performed on coils, resulting in high human resource utilization and low production efficiency. Furthermore, due to the small size of the coils and the poor precision of manual glue dispensing, glue leaks or misalignment can easily occur. Therefore, a glue dispensing jig has been designed to address these issues. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0032] First embodiment:

[0033] like Figures 1-14As shown, the present invention provides a dispensing jig, including a dispensing device and a coil jig 14, the dispensing device including a bottom box 1 and an operating table 45, a dispensing table 2 is provided at the upper end of the operating table 45, a jig seat 9 is installed on the dispensing table 2, a quick-release fixture 12 is installed on the jig seat 9, the coil jig 14 is detachably installed in the quick-release fixture 12, a plurality of coil slots 15 are opened in the coil jig 14, and circular coils 16 are respectively installed on the inner walls of the coil slots 15; a side box 44 is provided on one side of the dispensing table 2, and a horizontal box 3 is also provided at the upper end of the operating table 45, a dispensing machine 5 is installed on the horizontal box 3, and a driving device is provided inside the bottom box 1, which can drive the jig seat 9 to flip, the dispensing table 2 to move intermittently, and the dispensing machine 5 to move intermittently so that the dispensing machine 5 can dispense the circular coils 16 in sequence.

[0034] like Figures 1-4 、 Figure 13-14 As shown, the bottom box 1 and the operating table 45 are used to support and install the entire equipment. The dispensing machine 5, the jig seat 9, the quick-release fixture 12, the dispensing table 2, etc. can be set up in one group or multiple groups, and one group is used as an example; the dispensing table 2 can slide back and forth on the upper surface of the operating table 45, that is, the dispensing table 2 can only move back and forth on the operating table 45 through the guide rail slider limit, and the side box 44 is used to install the second motor 39 or the spur gear 8 and other components; the dispensing table 2 is used to install and support the jig seat 9, and the jig seat 9 is used to install and support the quick-release fixture 12 and the coil jig 14. When the jig seat 9 rotates, it can drive the quick-release fixture 12, the coil jig 14, and the circular coil 16 to rotate synchronously, even if the circular coil 16 rotates to a horizontal state for easy dispensing processing; the quick-release fixture 12 is used to protect and fix the coil jig 14, and the quick-release fixture 12 can be quickly disassembled and installed in the jig seat 9, which is convenient for quick replacement during processing; as shown Figure 4As shown, the coil jig 14 has multiple coil slots 15, and the round coils 16 are placed in the coil slots 15 respectively, and the round coils 16 are fixed under the action of friction so that the round coils 16 will not fall off; the worker presses the round coils 16 into the corresponding coil slots 15, and then loads the coil jig 14 onto the corresponding quick-release fixture 12. There are multiple backups of the quick-release fixture 12 and the coil jig 14. After the circular coils 16 are glued, the backups are assembled by removing the current quick-release fixture 12 and the coil jig 14. The quick-release fixture 12 and the coil fixture 14 can be loaded onto the fixture seat 9 to shorten the material change time; the driving device can drive the fixture seat 9 to flip, and the fixture seat 9 is in a vertical upward state in the initial position, which is convenient for replacing the quick-release fixture 12 and the coil fixture 14. When the fixture seat 9 is flipped, it can be rotated 90 degrees to make the fixture seat 9 and the coil fixture 14 in a horizontal state. Even if the circular coil 16 is placed horizontally, the driving device can drive the dispensing station 2 to move forward or backward intermittently. When the dispensing station 2 moves intermittently, it can drive the fixture seat 9 and the coil fixture 14 to move The tool 14 and the circular coil 16 move intermittently, that is, the circular coil 16 can be moved to the position directly below the glue dispenser 5 during each intermittent movement. The horizontal box 3 is used to install the glue dispenser 5. A driving component is provided on the horizontal box 3. The driving component can drive the glue dispenser 5 to move up and down or left and right, and adjust the initial position of the glue dispenser 5. The driving component and the glue dispenser 5 are all existing technologies and are not described in detail. The driving device can also drive the glue dispenser 5 to move up and down intermittently. When the glue dispenser 5 moves downward, it can dispense glue to the circular coil 16 directly below. By driving the device The fixture seat 9 is flipped to a horizontal state, and the dispensing table 2 intermittently moves backward and the dispensing machine 5 intermittently moves downward, so that the circular coil 16 can be moved to a horizontal state and stopped just below the dispensing machine 5. The dispensing machine 5 moves downward again to dispense glue on the circular coil 16, and the dispensing work is carried out in sequence to dispense glue on multiple circular coils 16 on the coil fixture 14. The whole process of automated dispensing replaces manual work, reduces the occupation of human resources, improves production efficiency, and has high accuracy and is not prone to glue leakage or glue error.

[0035] The fixture seat 9 is provided with a slot 10 that matches the quick-release fixture 12 , and a magnetic seat 11 is provided on the bottom wall of the slot 10 .

[0036] like Figure 4 As shown, the card slot 10 is adapted to be provided with a quick-release clamp 12. The quick-release clamp 12 is placed on the inner wall of the card slot 10, and the quick-release clamp 12 can be fixed on the fixture seat 9. The quick-release clamp 12 is made of stainless steel. Through the provided magnetic seat 11, the quick-release clamp 12 can be further adsorbed and fixed, so that the quick-release clamp 12 can be more stably fixed on the fixture seat 9. The magnetic seat 11 is an existing technology and will not be described in detail.

[0037] The two ends of the quick-release clamp 12 are respectively provided with flippable clamping plates 13 , which can fix the coil fixture 14 under the flipping clamping force of the clamping plates 13 .

[0038] like Figure 4 As shown, the splint 13 is hinged to the quick-release clamp 12 through a rotating shaft, and a coil spring is provided at the bottom of the splint 13. The coil spring can exert an inward turning force on the splint 13. When the coil jig 14 is placed on the quick-release clamp 12, the coil jig 14 can be fixed by applying the turning force of the splint 13 through the coil spring. When the coil jig 14 needs to be removed, the coil jig 14 can be removed by prying the splint 13 outward. The coil spring, hinged rotating shaft, etc. are all existing technologies and will not be repeated here. The friction force of an interference fit can also be set between the splint 13 and the hinge shaft instead of the coil spring, that is, when the splint 13 is flipped to a specified angle, it has a certain friction force, so that the splint 13 can fix the coil jig 14 when clamping the coil jig 14. The splint 13 and the coil jig 14 can also be fixed in the form of a buckle.

[0039] The driving device is a first motor 40, a second motor 39 and an electric lifting rod 43. The electric lifting rod 43 is installed at the upper end of the operating table 45, and the horizontal box 3 is installed at the lifting end of the electric lifting rod 43; the output end of the first motor 40 is provided with a screw 41, and a threaded seat 42 is threadedly connected on the outer surface of the screw 41, and the threaded seat 42 is fixedly connected to the lower end of the dispensing table 2; the output end of the second motor 39 is provided with a long rotating shaft, and the fixture seat 9 is fixedly connected to the outer surface of the long rotating shaft.

[0040] like Figure 13-14 As shown, the electric lifting rod 43 can be set one or two. When one electric lifting rod 43 is set, the bottom of the electric lifting rod 43 is fixed to the middle of the upper surface of the operating table 45, and the middle of the lower surface of the horizontal box 3 is fixed to the telescopic end of the electric lifting rod 43. When the electric lifting rod 43 is raised or lowered, it can drive the horizontal box 3 and the dispensing machine 5 to move up and down. When two lifting rods are set, as shown in FIG. Figure 13As shown, the bottom of the electric elastic telescopic rod 4 is fixed to both sides of the upper end surface of the operating table 45, and both sides of the horizontal box 3 are fixed to the telescopic ends of the electric lifting rod 43. When the electric lifting rod 43 is working, it can drive the horizontal box 3 and the dispensing machine 5 to move up and down; the first motor 40 is fixed to the lower end surface of the operating table 45, and the screw 41 is fixed to the output end of the first motor 40. When the first motor 40 is started, it can drive the screw 41 to rotate. One side of the outer surface of the screw 41 is rotatably connected to the bearing seat, and the bottom end of the bearing seat is fixed to the lower end surface of the operating table 45. The limit screw 41 can only rotate at the lower end of the operating table 45; when the first motor 40 is started and the screw 41 rotates, the threaded seat 42 and the dispensing table 2 can be driven to move forward or backward through the threaded connection between the screw 41 and the threaded seat 42; the side box 44 is fixed to the rear end surface of the dispensing table 2, The second motor 39 is fixed to the inner wall of the side box 44, and the long rotating shaft passes through the side wall of the dispensing table 2 and is rotatably connected inside the side wall. One end of the long rotating shaft is fixed to the second motor 39. When the second motor 39 is started, it can drive the long rotating shaft to rotate and the fixture seat 9 to flip, even if the fixture seat 9 is rotated 90 degrees to a horizontal state; a central processing unit or controller is also provided inside the bottom box 1. The central processing unit or controller can control the operation of the first motor 40, the second motor 39 and the electric elastic telescopic rod 4, thereby controlling the rotation of the fixture seat 9 to a horizontal state, the intermittent movement of the dispensing table 2 back and forth, and the intermittent movement of the dispensing machine 5 up and down. Under the coordination of the central processing unit or controller, the dispensing machine 5 performs dispensing work on multiple circular coils 16 in turn. The central processing unit, motor, electric lifting rod 43, etc. all belong to the existing technology and will not be repeated here.

[0041] Although the automated dispensing operation can be completed by the cooperation between the central processing unit of the driving device in the first embodiment and the motor, the electric elastic telescopic rod 4, etc., the cost of the central processing unit is high. When the dispensing operation is resumed after shutdown, it needs to be debugged again before the operation can be continued. For this purpose, another driving device that relies on a mechanical structure for dispensing processing is provided, which reduces costs and is simpler to operate.

[0042] Second embodiment:

[0043] The driving device is a driving motor 25, and the output end of the driving motor 25 is provided with a groove wheel 26 and a shift rod 27. The lower end of the dispensing table 2 is provided with a cross guide plate 24, and a plurality of notches 28 cooperating with the groove wheel 26 and a shift groove 48 cooperating with the shift rod 27 are opened on the end face of one side of the cross guide plate 24.

[0044] like Figure 8-Figure 9As shown, the drive motor 25 is fixed to the inner wall of the bottom box 1, the output end of the drive motor 25 is fixed to a rotating shaft, the groove wheel 26 and the shift rod 27 are fixed to the outer surface of the rotating shaft, and when the drive motor 25 is started, the groove wheel 26 and the shift rod 27 can be rotated; the lower end surface of the dispensing table 2 is fixed to the extension frame 23, and the cross guide plate 24 is fixed to the extension frame 23, which is equivalent to the cross guide plate 24 being fixed to the lower end of the dispensing table 2, that is, the cross guide plate 24 can only move forward and backward. The installation and shape of the cross guide plate 24, the notch 28, the shift groove 48, the groove wheel 26, and the shift rod 27 are as shown in FIG. Figure 8 As shown, when the groove wheel 26 and the shift rod 27 rotate, when the groove wheel 26 engages with the notch 28, the movement of the cross guide plate 24 and the dispensing table 2 can be restricted, that is, the dispensing table 2 is in an intermittent stop state at this time and will not move forward or backward. When the groove wheel 26 rotates to disengage from the notch 28, the shift rod 27 can rotate to meet and engage with the shift groove 48. Under the tossing of the shift rod 27, the cross guide plate 24 and the dispensing table 2 can be driven to move a distance. When the shift rod 27 rotates to disengage from the shift groove 48, the groove wheel 26 can rotate to engage with the notch 28 again, that is, after the dispensing table 2 moves to the specified position, it stops intermittently again and locks the position of the dispensing table 2; that is, when the drive motor 25 is working, the dispensing table 2 can be driven to move intermittently through the cooperation of the groove wheel 26 and the shift rod 27 with the notch 28 and the shift groove 48.

[0045] The inner wall of the operating table 45 is provided with a movable telescopic plate, which includes an outer plate 31 and an inner plate 34 that can move up and down. The outer plate 31 is slidably connected to the inner wall of the operating table 45. The inner wall of the operating table 45 is also provided with a first spring 36 that cooperates with the outer plate 31. The inner plate 34 is slidably connected to the inner wall of the outer plate 31, and the upper end of the inner plate 34 is slidably connected to the lower end surface of the horizontal box 3.

[0046] like Figure 1 、 Figure 12 As shown, the telescopic plate can move left and right on the inner wall of the operating table 45. A rectangular hole is opened on the operating table 45. The outer plate 31 slides left and right on the inner wall of the rectangular hole. The first spring 36 is installed in the rectangular hole. The first spring 36 always has a driving force on the outer plate 31, even if the telescopic plate and the extension plate 35 can be away from the pressing plate 38 under normal conditions and lose contact with the pressing plate 38; the inner plate 34 can be slidably connected to the inner wall of the outer plate 31 up and down, that is, the inner plate 34 can move up and down on the inner wall of the outer plate 31, and the inner plate 34 is slidably connected to the lower end surface of the horizontal box 3, that is, when the telescopic plate moves left and right, the inner plate 34 can always maintain connection with the horizontal box 3; as shown Figure 1As shown, elastic telescopic rods 4 are fixed on the left and right sides of the upper end of the operating table 45 respectively, and the horizontal box 3 is fixed to the telescopic ends of the two elastic telescopic rods 4. The elastic telescopic rods 4 can limit the horizontal box 3 to move up and down. The elastic telescopic rods 4 include an inner rod and an outer tube. The inner rod is slidably connected to the inner wall of the outer tube. The inner wall of the outer tube is provided with a spring that matches the inner rod. The spring has an upward driving force on the inner rod, so that the inner rod and the horizontal box 3 are in the topmost state under normal conditions; when the inner plate 34 moves downward, it can drive the horizontal box 3 to move downward. When the inner plate 34 is not subject to force, the horizontal box 3 can move upward to the top position and reset under the extension and contraction of the elastic telescopic rods 4. When the outer plate 31 moves left and right, it can drive the inner plate 34 to move left and right. When the inner plate 34 moves left and right, it can move left and right on the lower end surface of the horizontal box 3, and the inner plate 34 can always remain connected to the horizontal box 3.

[0047] A cylindrical intermittent cam 29 is coaxially fixed to the upper end of the groove wheel 26, and a first sliding pin 30 is engaged on the outer surface of the cylindrical intermittent cam 29. A pull plate 37 is slidably connected to the inner wall of the operating table 45. The upper end surface of the pull plate 37 is fixed to the pressing plate 38, and the first sliding pin 30 is fixed to the lower end surface of the pressing plate 38. An extension plate 35 that cooperates with the pressing plate 38 is fixed to the inner plate 34.

[0048] like Figure 10-12 As shown, the pull plate 37 is connected to the inner wall of the operating table 45 by sliding up and down. Through the engagement of the cylindrical intermittent cam 29 and the first sliding pin 30, when the cylindrical intermittent cam 29 rotates following the groove wheel 26, the first sliding pin 30, the pull plate 37, and the pressure plate 38 can be intermittently moved up and down; when the telescopic plate moves toward one end close to the pull plate 37, the extension plate 35 can be moved to a position below the pressure plate 38. When the first sliding pin 30, the pull plate 37, and the pressure plate 38 move downward, the extension plate 35 can be pressed downward, that is, the inner plate 34, the horizontal box 3, and the dispensing machine 5 move downward, that is, through the mutual cooperation of the cylindrical intermittent cam 29, the first sliding pin 30 and the elastic telescopic rod 4, the dispensing machine 5 can be driven to move up and down intermittently.

[0049] A second sliding pin 33 is fixedly connected to the lower end of the outer plate 31 , and a trapezoidal guide plate 32 is fixedly connected to the transverse guide plate 24 . The trapezoidal guide plate 32 is provided with an inclined surface 49 and a straight surface 50 that match the second sliding pin 33 .

[0050] like Figure 11As shown, inclined surfaces 49 are respectively provided on the end surfaces of both sides of the trapezoidal guide plate 32, and a straight surface 50 is provided in the middle. The second sliding pin 33 can always be in contact with the inclined surface 49 or the straight surface 50 of the trapezoidal guide plate 32 under the elastic force of the first spring 36; when the dispensing platform 2, the transverse guide plate 24, and the trapezoidal guide plate 32 move to make the straight surface 50 contact and engage with the second sliding pin 33, the second sliding pin 33, the telescopic plate, and the extension plate 35 can be at one end close to the pull plate 37, that is, when the pressing plate 38 moves downward, it can squeeze the extension plate 35 to move downward. When the dispensing platform 2, the transverse guide plate 24, and the trapezoidal guide plate 32 move forward or backward to the end point position, the second sliding pin 33 will engage with the inclined surface 49, and under the engagement of the inclined surface 49, the second sliding pin 33, the telescopic plate, and the extension plate 35 can be moved away from the pull plate 37. , that is, when the pressing sheet 38 continues to move downward, the extension plate 35 is no longer driven to move downward, that is, the corresponding dispensing machine 5 no longer moves downward, which can provide a certain working time for the fixture seat 9 to flip to a horizontal state; when the second sliding pin 33 contacts and engages with the straight surface 50, through the cooperation of the cylindrical intermittent cam 29 and the first sliding pin 30 and the groove wheel 26, the shift rod 27 and the recess 28, and the shift groove 48, when the driving motor 25 is working, the dispensing table 2 can be moved backward for a distance and then stopped intermittently.
