Description

Technical Field

[0001] This invention relates to the field of lampshade potting technology, specifically to a small acoustic and light lampshade potting fixture and its potting method. Background Technology

[0002] A lampshade is a cover placed around the flame of a lamp or on a light bulb to focus light or protect it from wind and rain. A lampshade serves more than just to concentrate light; it also helps prevent electric shock and protects the eyes. Therefore, most lamps have lampshades. During the manufacturing process, a dispensing machine is often used to bond and secure the lampshade to the lamp fixture.

[0003] Patent application number CN202020022454.X discloses an automatic lampshade dispensing and assembly machine, including a base frame, a fixed frame, an X-axis, a Y-axis, a Z-axis, a mounting plate, a dispensing valve, a first support frame, a first flipping clamp, a guide rail, a second support frame, a second flipping clamp, a pushing assembly platform, and rollers. The fixed frame is vertically fixed to one side of the top of the base frame, and the X-axis is fixedly mounted on the top of the fixed frame. This automatic lampshade dispensing and assembly machine uses the X, Y, and Z axes to adjust the position of the dispensing valve, enabling dispensing from multiple spatial directions. Simultaneously, the distance between the second and first flipping clamps is adjusted via the guide rail and the pushing assembly platform. The first and second flipping clamps can rotate around the first and second support frames to adjust their positions, adapting to clamping various types of lampshades and facilitating operation.

[0004] Although the aforementioned patent documents can adaptably clamp different types of lampshades, in actual use, if the lampshade is slightly tilted when the clamp is holding it, the glue sprayed from the glue gun will fall onto the LED beads of the lampshade during the glue application process, resulting in defective products. At the same time, after the lampshade is glued, it cannot be automatically removed and collected. Personnel need to manually remove the lampshades one by one, which is time-consuming and labor-intensive, and not efficient or convenient. Summary of the Invention

[0005] The purpose of this invention is to provide a small acoustic and light lamp cover potting fixture and its potting method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

A fifth motor connected to the rectangular frame is fixedly connected to the end of the connecting shaft that passes through the rectangular frame.

[0022] The present invention also provides a method for potting a small acoustic and light lampshade, which is implemented according to a potting fixture for a small acoustic and light lampshade, and includes the following specific steps:

[0023] S1. Control the drive unit to drive the rack to move, the rack to drive the gear ring to rotate, the gear ring to drive the gear to rotate, and the gear to drive the first guide post and slider to move using the first sliding groove rod, so that multiple arc plates move away from each other radially at the same time. Then, the lamp cover is placed inside the gear ring. After that, control the drive unit to drive the rack to drive the gear ring to reverse, so that the arc plate can clamp the small sound and light lamp cover and complete the positioning.

[0024] S2. Start the first motor to drive the first threaded rod to rotate and adjust the front and rear direction of the dispensing machine body. Start the second motor to drive the second threaded rod to rotate and adjust the left and right position of the dispensing machine body. Start the sixth motor to drive the first connecting rod to rotate and adjust the height of the dispensing machine body. Start the fourth motor to make the dispensing machine body rotate and adjust its horizontal angle. Then start the fifth motor to drive the dispensing machine body to rotate and adjust its tilt angle. Then perform the dispensing work.

[0025] S3. After the glue-filling process is completed, start the third motor to drive the second slide bar to rotate counterclockwise. The second guide column drives the displacement plate and the clamping assembly to move towards the glue-filling assembly, aligning the clamping assembly with the lampshade. Start the electric telescopic rod to drive the displacement plate to move upward, bringing the bottoms of the grippers closer together to clamp the lampshade. The third motor reverses, causing the clamping assembly to lift the lampshade, remove the lampshade, and place it inside the collection box, completing the collection of the lampshade.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] The technical effects and advantages of this invention are as follows:

[0028] 1. In this invention, the control device starts the third motor to drive the second sliding rod to rotate. The second sliding rod moves the second guide column through the limiting of the sliding sleeve and the L-shaped rod, eventually making the clamping component connect with the lampshade. The electric telescopic rod is started to drive the gripper to clamp the lampshade. The second sliding rod is controlled to rotate in reverse so that the clamping component moves the lampshade to the collection box. Then the electric telescopic rod is extended so that the gripper moves away from each other and the lampshade falls into the collection box, completing the collection of the lampshade. This achieves the effect of automatically taking out and collecting the small sound and light lampshade after glue is applied.

[0029] 2. In this invention, the control drive unit moves the rack through the movable plate, and the rack drives the gear to rotate through the gear ring. The gear uses the first sliding rod and the first guide post to drive multiple sets of arc plates to move away from each other. Then, the small sound and light lamp cover is placed inside the gear ring. The drive unit drives the gear to reverse, so that the slider moves continuously along the straight sliding groove towards the center area of ​​the gear ring. This allows the arc plates and arc clamping blocks to clamp the small sound and light lamp covers of different diameters, ensuring the stability of the small sound and light lamp cover during the glue pouring process.

[0030] 3. In this invention, by detecting the elastic deformation of the elastic element, it can be determined whether the lampshade is tilted when the clamping adjustment component holds the lampshade. If tilting occurs, a base plane is constructed based on the elastic deformation of the elastic element, and the clamping adjustment component is adjusted by controlling the inclination of the base plane to keep the lampshade in a stable state. At the same time, by detecting the curvature of the elastic element, the amount of glue in the lampshade during glue dispensing can be obtained. Based on the constructed base plane, the actual amount that the lampshade can withstand can be obtained, thereby avoiding the phenomenon of glue overflowing from the lampshade due to excessive glue in the lampshade during the continuous glue dispensing process of the dispensing machine body.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] Example 1

[0048] Reference Figures 1 to 8 A small sound and light lampshade potting fixture includes a worktable 1, a placement plate 2 fixedly connected to the upper surface of the worktable 1, and a clamping and adjusting component arranged in an array on the placement plate 2, which is used to clamp and adjust the lampshade.

[0049] The side of the placement plate 2 is provided with a potting assembly that is connected to the workbench 1. The potting assembly is used to pot the lampshade with glue.

[0050] A guide plate 25 located on the side of the placement plate 2 is fixedly connected to the upper end of the workbench 1. The outer surface of the guide plate 25 is provided with an inverted L-shaped through groove 42. A second guide post 24 is slidably connected inside the through groove 42. A displacement component is provided at the end of the second guide post 24 away from the guide plate 25 to drive the second guide post 24 to move. A displacement plate 8 is fixedly connected at the end of the second guide post 24 away from the displacement component. A clamping component corresponding to the clamping adjustment component is provided on the lower end of the displacement plate 8.

[0051] Specifically, the displacement assembly includes a horizontal groove 52 located above the through groove 42. An L-shaped rod 22 is slidably connected inside the horizontal groove 52. The vertical part of the L-shaped rod 22 is slidably connected to a sliding sleeve 23 that is fixedly connected to the second guide post 24. A second sliding groove rod 21 that is slidably connected to the second guide post 24 is provided between the sliding sleeve 23 and the guide plate 25. A third motor 20 located above the placement plate 2 is fixedly connected to the end of the second sliding groove rod 21 away from the sliding sleeve 23.

[0052] Specifically, the gripping assembly includes connecting blocks 35 fixedly connected to the bottom of the displacement plate 8 and arranged in an array. Each connecting block 35 has a fixed plate 36 fixedly connected to its bottom. The lower end face of the fixed plate 36 is provided with grippers 40 arranged in an array and hinged to the fixed plate 36. Each gripper 40 is hinged to a third link 39 at the end near the fixed plate 36. The end of the third link 39 away from the gripper 40 is hinged to a displacement plate 38. An electric telescopic rod 37 is fixedly connected to the top of the displacement plate 38. The telescopic end of the electric telescopic rod 37 passes through the fixed plate 36 and is fixedly connected to the displacement plate 38. The fixed end of the electric telescopic rod 37 is fixedly connected to the displacement plate 8. A collection box 33 is placed below the displacement plate 8.

[0053] After the glue dispensing is completed, the control equipment starts the third motor 20 to drive the second sliding rod 21 to rotate. The second sliding rod 21 drives the second guide post 24 to slide towards the glue dispensing assembly. The second sliding rod 21, through the second guide post 24, simultaneously drives the sliding sleeve 23 and the L-shaped rod 22 to move towards the glue dispensing assembly, so that the displacement plate 8 and the clamping assembly move horizontally along the horizontal part of the through groove 42, so that the clamping assembly moves above the clamping adjustment assembly and aligns with the lampshade. The third motor 20 drives the second sliding rod 21 to continue rotating, so that the second guide post 24 moves downward along the vertical part of the through groove 42. The second guide post 24 drives the sliding sleeve 23 to slide downward from the top of the L-shaped rod 22, so that the clamping assembly moves downward. Then, the electric telescopic rod 37 is started to drive the displacement plate 38 to move upward. Under the action of the third connecting rod 39, the gripper 4... Rotating the gripper 40 brings its bottoms closer together, allowing it to grip the lampshade. Then, controlling the third motor 20 drives the second sliding rod 21 to rotate in the opposite direction, causing the gripping assembly to move the lampshade upward along the vertical part of the through groove 42, removing the lampshade from the gripping adjustment assembly. As the second sliding rod 21 continues to rotate, the second guide post 24 moves along the horizontal part of the through groove 42 to the end of the through groove 42 away from the glue-pouring assembly, positioning the lampshade above the collection box 33. Then, extending the electric telescopic rod 37 causes the gripper 40 to move away from each other, lowering the lampshade into the collection box 33, thus completing the collection of the lampshade. This achieves an automatic removal and centralized collection of glue-pouring small sound and light lampshades, eliminating the need for manual removal of glue-pouring lampshades one by one, making it more convenient and labor-saving.

[0054] Specifically, the clamping adjustment assembly includes a fixed ring 9 connected to the placement plate 2 via a bracket. A toothed ring 10 is rotatably connected to the inner side of the fixed ring 9. The inner ring of the toothed ring 10 is provided with an array of sliders 14. The sliders 14 are pushed by a power assembly and move toward the center of the toothed ring 10.

[0055] Specifically, the power assembly includes symmetrically arranged fixed blocks 19, with slide rods 18 arranged symmetrically between the two fixed blocks 19, and movable blocks 48 slidably connected to the two slide rods 18. A rack 16 is provided on the side of the movable block 48, and the rack 16 meshes with the tooth groove 49 opened on the outside of the tooth ring 10.

[0056] A spring 17 is provided between one side of the movable block 48 and the fixed block 19. The spring 17 is sleeved on the slide rod 18. A driving member 50 is provided between the other side of the movable block 48 and the fixed block 19. The driving member 50 is used to drive the movable block 48 to slide on the slide rod 18.

[0057] Specifically, the power assembly also includes gears 11 that mesh with the inner teeth of the gear ring 10 and are arranged in an array. The bottom of the gears 11 is rotatably connected to the top of the placement plate 2. A first sliding rod 12 is fixedly connected to the top of the gears 11. A first guide post 13 is provided inside the sliding groove of the first sliding rod 12. The first guide post 13 is fixedly connected to the top of the fixed horizontal plate 44.

[0058] The placement plate 2 has a linear slide groove 51 for sliding the slider 14. The linear slide groove 51 is located on the side of the gear 11.

[0059] The control drive 50 drives the rack 16 to move. The rack 16 drives the gear ring 10 to rotate through the tooth groove 49 on the gear ring 10. The teeth of the inner ring of the gear ring 10 drive the gear 11 to rotate. The gear 11 drives the first guide post 13 and the slider 14 to move through the first sliding rod 12, so that multiple arc plates 15 move away from each other radially at the same time. Then, the small sound and light lamp cover is placed into the inner ring of the gear ring 10. At this time, the control drive 50 drives the rack 16 to rotate the gear ring 10 in reverse. The gear ring 10 drives the gear 11 to rotate in reverse, so that it returns to the initial position, so that the arc plates 15 can clamp the small sound and light lamp cover, thereby completing the positioning. This can achieve a uniform and stable clamping effect for small sound and light lamp covers of different diameters, ensuring the stability of the small sound and light lamp cover during the potting process, and the small sound and light lamp cover is not easily deformed due to uniform force.

[0060] Specifically, the glue-dispensing assembly includes a slide plate 3 fixedly connected to the workbench 1. A first threaded rod 4 is rotatably connected inside the slide plate 3. A first motor 5 connected to the slide plate 3 is fixedly connected to the end of the first threaded rod 4. An L-shaped column 6 that is radially slidably connected to the slide plate 3 is threaded onto the first threaded rod 4. A second threaded rod 41 is rotatably connected to the horizontal part of the L-shaped column 6. A second motor 7 connected to the vertical part of the L-shaped column 6 is fixedly connected to the end of the second threaded rod 41.

[0061] Specifically, the dispensing assembly also includes a threaded block 26 that is threadedly engaged with the second threaded rod 41. The threaded block 26 is radially slidably connected to the horizontal portion of the L-shaped column 6. A first connecting rod 27 is rotatably connected to the threaded block 26. A sixth motor 34 is fixedly connected to the end of the first connecting rod 27 on the threaded block 26. A second connecting rod 28 is rotatably connected to the end of each of the two first connecting rods 27 away from the threaded block 26. A fourth motor 29 is rotatably connected to the end of each of the two second connecting rods 28 away from the first connecting rod 27. A rectangular frame 30 is fixedly connected to the output end of the fourth motor 29. The dispensing machine body 32 is fixedly connected to the inside of the rectangular frame 30 through a connecting shaft 53. A fifth motor 31 connected to the rectangular frame 30 is fixedly connected to the end of the connecting shaft 53 that passes through the rectangular frame 30.

[0062] By starting the first motor 5 to drive the first threaded rod 4 to rotate, the L-shaped column 6 can be moved back and forth, adjusting the front and back direction of the dispensing machine body 32. Then, starting the second motor 7 to drive the second threaded rod 41 to rotate, causing the threaded block 26 to slide left and right, adjusting the left and right position of the dispensing machine body 32. Then, starting the sixth motor 34 to drive the first connecting rod 27 to rotate, forming different angles between the first connecting rod 27 and the second connecting rod 28, adjusting the height of the dispensing machine body 32. Then, starting the fourth motor 29 to rotate the dispensing machine body 32, adjusting its horizontal angle. Then, starting the fifth motor 31 to rotate the dispensing machine body 32, adjusting its tilt angle. Thus, the orientation and angle of the dispensing machine body 32 can be flexibly adjusted, thereby improving the flexibility of dispensing and making the dispensing work more precise.

[0063] Example 2

[0064] While the above embodiments can solve the problem of the lampshade not being automatically removed and collected after glue application, in actual use, if the lampshade is tilted when the clamp holds it, glue sprayed from the glue gun may fall onto the LED beads in the lampshade, resulting in defective products. Therefore, a modification is made to the technical solution based on Embodiment 1, and the modified technical solution is as follows.

[0065] refer to Figures 9 to 10 A small sound and light lampshade potting fixture includes a worktable 1, a placement plate 2 fixedly connected to the upper surface of the worktable 1, and a clamping and adjusting component arranged in an array on the placement plate 2, which is used to clamp and adjust the lampshade.

[0066] The side of the placement plate 2 is provided with a potting assembly that is connected to the workbench 1. The potting assembly is used to pot the lampshade with glue.

[0067] A guide plate 25 located on the side of the placement plate 2 is fixedly connected to the upper end of the workbench 1. The outer surface of the guide plate 25 is provided with an inverted L-shaped through groove 42. A second guide post 24 is slidably connected inside the through groove 42. A displacement component is provided at the end of the second guide post 24 away from the guide plate 25 to drive the second guide post 24 to move. A displacement plate 8 is fixedly connected at the end of the second guide post 24 away from the displacement component. A clamping component corresponding to the clamping adjustment component is provided on the lower end of the displacement plate 8.

[0068] The clamping adjustment assembly includes a fixed ring 9 connected to the placement plate 2 via a bracket. A toothed ring 10 is rotatably connected to the inner side of the fixed ring 9. The inner ring of the toothed ring 10 is provided with an array of sliders 14. The sliders 14 are pushed by a power assembly and move toward the center of the toothed ring 10. The sliders 14 include a telescopic part 43 that is slidably connected to the placement plate 2. A fixed horizontal plate 44 is fixedly connected to the top end of the telescopic part 43. An arc-shaped plate 15 is fixedly connected to the end of the fixed horizontal plate 44 away from the telescopic part 43. An arc-shaped clamping block 46 is connected to the side of the arc-shaped plate 15 near the center of the toothed ring 10 via an array of elastic members 45.

[0069] Specifically, the arc-shaped plate 15 and the arc-shaped clamping block 46 are slidably connected, and the two sides of the arc-shaped plate 15 and the arc-shaped clamping block 46 are parallel to each other.

[0070] Specifically, the side of the arc-shaped clamping block 46 away from the elastic element 45 is provided with a flexible layer 47.

[0071] In use, the drive component 50 is first extended. The drive component 50 includes an electric push rod. When the drive component 50 extends, it drives the movable block 48 to move axially along the slide rod 18 while simultaneously compressing the spring 17. During the movement, the movable block 48 drives the rack 16 to move. Since the rack 16 meshes with the tooth groove 49 on the outer side of the gear ring 10, during the movement of the rack 16, the rack 16 synchronously drives the gear ring 10 to rotate through the tooth groove 49. When the gear ring 10 rotates, the teeth inside the gear ring 10 synchronously drive the circumferentially distributed gears 11 inside the gear ring 10 to rotate. Since the top of the gear 11 passes through the first slide rod... The groove rod 12 is connected to the first guide post 13 and the slider 14, and the slider 14 is radially slidably connected to the straight groove 51 on the placement plate 2. As a result, when the gear 11 rotates, the groove on the first groove rod 12 presses against the first guide post 13, causing the slider 14 below the first guide post 13 to slide radially along the straight groove 51 toward the inner ring of the gear ring 10. When the slider 14 moves, it simultaneously drives the arc plate 15 and the arc clamping block 46 to move along the straight groove 51 toward the inner ring of the gear ring 10, thereby expanding the central area of ​​the inner ring of the gear ring 10 so that the lampshade can be easily placed in.

[0072] The lampshade is placed inside the gear ring 10 with the glue-filling port on the lampshade facing the glue-filling assembly. Then, the control drive 50 drives the rack 16 to move via the movable plate, thereby causing the rack 16 to rotate the gear ring 10 in reverse. This, in turn, causes the gear ring 10 to rotate the gear 11 in reverse. The gear 11 presses against the first guide post 13 via the first slide rail 12, causing the slider 14 to advance along the straight slide rail 51 towards the center area of ​​the gear ring 10. This causes the arc plate 15 and the arc clamping block 46 on the slider 14 to press against the lampshade placed inside the gear ring 10. Since the arc clamping block 46 is located on the arc plate 15, the lampshade is pressed against the gear ring 10. 5. The side away from the slider 14 is positioned so that the arc-shaped clamping block 46 first contacts the lampshade. Simultaneously, since the arc-shaped clamping block 46 and the arc-shaped plate 15 are connected by an elastic element 45, and the two sides of the arc-shaped clamping block 46 and the arc-shaped plate 15 are parallel, after the arc-shaped clamping block 46 makes squeezing contact with the lampshade, the arc-shaped clamping block 46 will simultaneously squeeze the elastic element 45. The elastic element 45 is a compression spring. Under the limitation of the elastic element 45, the arc-shaped clamping block 46 moves towards the arc-shaped plate 15. After the contraction amount of the driving member 50 reaches the set value, the arc-shaped clamping block 46 completes the clamping of the lampshade.

[0073] In this embodiment, the arc-shaped clamping blocks 46 and the arc-shaped plates 15 are set in three groups. After the three groups of arc-shaped clamping blocks 46 have finished clamping the lampshade, since the elastic elements 45 between the arc-shaped clamping blocks 46 and the arc-shaped plates 15 are arranged in an array, and a pressure sensor is provided at the connection between the elastic elements 45 and the arc-shaped plates 15, the pressure sensor is used to detect the elastic deformation of the elastic elements 45. By detecting the elastic deformation of the elastic elements 45 between the three groups of arc-shaped clamping blocks 46 and the arc-shaped plates 15, it can be determined whether the lampshade is tilted when the arc-shaped clamping blocks 46 and the arc-shaped plates 15 are clamping the lampshade.

[0074] If the lampshade does not tilt, it means that the elasticity of the elastic element 45 between the three sets of arc-shaped clamping blocks 46 and the arc-shaped plate 15 at the same height should be within the same set range.

[0075] If the lampshade is tilted, it means that the elastic variables of the elastic elements 45 between the three sets of arc-shaped clamping blocks 46 and arc-shaped plates 15 are different at the same height. At this time, the elastic element 45 with the largest elastic variable between the three sets of arc-shaped clamping blocks 46 and arc-shaped plates 15 is taken as the base point. The three base points are connected in series to obtain a base plane, and then the tilt of this base plane can be obtained. After that, the highest point of the base plane is set as the fixed point.

[0076] Since the slider 14 includes a telescopic part 43 and a fixed horizontal plate 44, and the telescopic part 43 is an electric push rod, in the initial state, the telescopic part 43 is in a retracted state, and there is a certain distance between the fixed horizontal plate 44 and the first sliding rod 12. The length of the first guide post 13 is greater than the distance between the fixed horizontal plate 44 and the first sliding rod 12. The telescopic part 43 corresponding to the other base points, except for the fixed point, is extended, thereby eliminating the tilt state of the base plane. Since the side of the arc-shaped clamping block 46 away from the elastic member 45 is provided with a flexible layer 47, which includes a rubber layer, during the extension of the telescopic part 43, the flexible layer 47 contacts the edge of the lampshade, thereby preventing damage to the lampshade.

[0077] Although the tilt of the base plane can be eliminated by extending the telescopic part 43, since the distance between the fixed horizontal plate 44 and the first sliding rod 12 is constant, if the tilt angle of the lampshade is too large, causing the top of the fixed horizontal plate 44 to contact the bottom of the first sliding rod 12, the tilt of the base plane will still not be eliminated. At this time, the tilt amount of the reference plane formed by the three base points can still be obtained by detecting the reference plane. If the tilt amount of the reference plane exceeds the set value, it needs to be rearranged.

[0078] If the tilt of the reference plane does not exceed the set value, after the glue dispensing assembly moves above the clamping adjustment assembly, the control settings, based on the tilt of the reference plane at this time, first control the fourth motor 29 to start, the fourth motor 29 drives the rectangular frame 30 to rotate, thereby adjusting the angle of the fifth motor 31 and the connecting shaft 53. Then, control the fifth motor 31 to drive the connecting shaft 53 to rotate, thereby changing the angle between the dispensing machine body 32 and the placement plate 2 to adapt to the tilt of the reference plane. Then, control the sixth motor 34 to rotate, the sixth motor 34 drives the dispensing machine body 32 to descend through the first connecting rod 27 and the second connecting rod 28, thereby aligning the dispensing machine body 32 with the glue dispensing port of the lampshade for glue dispensing.

[0079] During the dispensing process, the arc-shaped clamping block 46 and the arc-shaped plate 15 are connected by an elastic element 45, and the two sides of the arc-shaped clamping block 46 and the arc-shaped plate 15 are parallel. The elastic element 45 includes a compression spring and is equipped with a bending sensor. As the dispensing machine body 32 continuously dispenses glue to the lampshade, the weight of the lampshade continuously increases, causing the lampshade to move the arc-shaped clamping block 46 downward, which in turn causes the elastic element 45 to bend. By detecting the bending degree of the elastic element 45, the amount of glue inside the lampshade can be obtained. Since the amount of glue that the lampshade can withstand is limited, and since the reference plane is in an inclined state, detecting the bending degree of the elastic element 45 can prevent the phenomenon of glue overflowing from the lampshade due to excessive glue inside the lampshade during the continuous dispensing process of the dispensing machine body 32.

[0080] After the glue is applied, the control equipment restores the glue application assembly to its initial state. Then, it controls the clamping assembly to clamp the lampshade. Since the clamping assembly and the clamping adjustment assembly are one-to-one, and the jaws 40 and the clamping plate are misaligned, when the clamping assembly clamps the lampshade which is tilted (i.e., the base plane is tilted), the electric telescopic rod 37 is partially retracted, allowing the jaws 40 to partially clamp the lampshade. Then, the clamping adjustment assembly is operated, causing the curved plate 15 and the curved clamping block 46 to lose their grip on the lampshade. At this point, because the jaws 40 and... When the lowest point of the lampshade contacts the ground, the lampshade deflects in a tilted direction under the action of gravity, so that the entire edge of the lampshade falls onto the bent part of the gripper 40. Then, the electric telescopic rod 37 is controlled to retract, so that the gripper 40 first fully clamps the lampshade. Then, the third motor 20 is controlled to drive the second sliding rod 21 to rotate in the opposite direction, so that the gripping component removes the lampshade from the gripping adjustment component and transports the lampshade to the top of the collection box 33. Then, the electric telescopic rod 37 is extended, so that the gripper 40 moves away from each other, and the lampshade is lowered and falls into the collection box 33, completing the collection of the lampshade.

[0081] Example 3

[0082] The present invention also provides a method for potting a small acoustic and light lampshade, which is implemented according to a potting fixture for a small acoustic and light lampshade, and includes the following specific steps:

[0083] S1. The control drive unit 50 drives the rack 16 to move, the rack 16 drives the gear ring 10 to rotate, the gear ring 10 drives the gear 11 to rotate, and the gear 11 drives the first guide post 13 and the slider 14 to move through the first sliding groove rod 12, so that multiple arc plates 15 move away from each other radially at the same time. Then the lamp cover is placed inside the gear ring 10. After that, the control drive unit 50 drives the rack 16 to drive the gear ring 10 to reverse, so that the arc plates 15 can clamp the small sound and light lamp cover and complete the positioning.

[0084] S2. Start the first motor 5 to drive the first threaded rod 4 to rotate, and adjust the front and back direction of the dispensing machine body 32. Start the second motor 7 to drive the second threaded rod 41 to rotate, and adjust the left and right position of the dispensing machine body 32. Start the sixth motor 34 to drive the first connecting rod 27 to rotate, and adjust the height of the dispensing machine body 32. Start the fourth motor 29 to make the dispensing machine body 32 rotate and adjust its horizontal angle. Then start the fifth motor 31 to drive the dispensing machine body 32 to rotate and adjust its tilt angle. Then perform the dispensing work.

[0085] S3. After the glue-filling process is completed, start the third motor 20 to drive the second slide bar 21 to rotate counterclockwise. The second guide post 24 drives the displacement plate 8 and the clamping assembly to move towards the glue-filling assembly, so that the clamping assembly is aligned with the lamp cover. Start the electric telescopic rod 37 to drive the displacement plate 38 to move upward, so that the bottom of the grippers 40 are close to each other to clamp the lamp cover. The third motor 20 reverses, so that the clamping assembly drives the lamp cover to rise, remove the lamp cover, and place it inside the collection box 33 to complete the collection of the lamp cover.
