[0004]为了解决现有技术中电阻套的装配过程中采用多工位加工效率低质量不稳定的问题,本发明提供了一种LED灯珠用智能型电阻机
[0017] The assembly device for resistors, resistor sleeves, and resistor caps provided by this invention synchronously completes three processes—grabbing the resistor cap, clamping the resistor cap and resistor, and clamping the resistor sleeve—through an open control drive component. This reduces the existing two-station assembly to a single station, thereby saving labor costs. Furthermore, the entire process is semi-automatically driven by the equipment, with fixed gripping positions and fixed clamping distances. Therefore, within the allowable error range, the overall quality of the assembled resistors is almost identical, thus reducing the probability of defective products. Actual testing shows that the defect rate of resistors assembled using this device is less than 5%. This is mainly due to the inherent errors in components such as the resistor sleeve and resistor cap, as well as errors inherent in the device itself. Therefore, disregarding these two factors, the overall yield rate of resistors assembled using this device is high. Moreover, assembly can be completed quickly with only control; the assembly time for one resistor is approximately 3 seconds, which is equivalent to saving about 70% of the time required for two-station assembly. This is mainly because two-station assembly involves additional transfer time and two picking times compared to this device.

Abstract
Description
Technical Field
[0001] This invention relates to the field of resistor assembly technology, and in particular to an intelligent resistor machine for LED beads. Background Technology
[0002] As decorative lights and ambient lights, multiple LEDs are used in series, parallel, or a combination of both to achieve a decorative effect. At the same time, in order to achieve a certain effect, it is necessary to use a corresponding resistor in series in the circuit to meet the requirements of the LEDs. Otherwise, the LEDs may be damaged due to excessive power, and the desired effect cannot be achieved.
[0003] Existing resistors are not simply connected to the circuit as resistive components. Considering aesthetics, reusability, and safety, current technology employs a packaging structure for the resistors, specifically including an outer resistor sleeve and an upper resistor cap. During assembly, because the resistor cap and the upper part of the resistor are tightly fitted, the resistor cap and resistor are assembled together first, and then a special resistor gripper is used to grip and assemble it with the resistor sleeve. To meet this requirement, two workstations are often set up: one for assembling the resistor cap and resistor, and the other for assembling the resistor sleeve. However, manual assembly is time-consuming and labor-intensive. Furthermore, during the clamping assembly process, human error leads to a high defect rate and a high rate of detachment during subsequent use. Summary of the Invention
[0004] To address the issues of low efficiency and unstable quality in the assembly of resistor sleeves using multi-station processing in existing technologies, this invention provides an intelligent resistor machine for LED beads.

Therefore, within the allowable error range, the overall quality of the assembled resistors is almost identical, thus reducing the probability of defective products. Actual testing shows that the defect rate of resistors assembled using this device is less than 5%. This is mainly due to the inherent errors in components such as the resistor sleeve and resistor cap, as well as errors inherent in the device itself. Therefore, disregarding these two factors, the overall yield rate of resistors assembled using this device is high. Moreover, assembly can be completed quickly with only control; the assembly time for one resistor is approximately 3 seconds, which is equivalent to saving about 70% of the time required for two-station assembly. This is mainly because two-station assembly involves additional transfer time and two picking times compared to this device. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] In the description of this invention, it should be understood that the terms "front," "rear," "left," "right," "up," and "down," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. The technical solutions of the various embodiments in this invention can be combined, and the technical features in the embodiments can also be combined to form new technical solutions.
[0028] The technical solution provided by this invention is as follows:
[0029] As attached Figure 1 As shown, the overall structure of the equipment can be seen to include the following main parts: 1. Workbench 1; 2. Drive section; 3. Moving support section; 4. Moving section; 5. Gripping section; 6. Gripping and pressing section; 7. Pressing and assembly section; 8. Cover gripping station section; 9. Resistor gripping station assembly.
[0030] As attached Figures 1-6 The diagram shows a three-dimensional representation of the drive unit. As can be seen from the diagram, the drive unit uses conventional drive components, specifically: a stepper motor and a switch fixedly mounted on the worktable 1, connected to each other; and two bearing seats mounted on the worktable 1. A cam drive rod 59 passes through the two bearing seats. The cam drive rod 59 is equipped with a moving cam 10, a pressing cam 33, a gripping and pressing cam 25, a closing cam 58, and a blocking cam 43, etc. Multiple cams rotate synchronously under the drive of the cam drive rod 59. Simultaneously, a pulley and a synchronous belt connect the stepper motor to the cam drive rod 59 at one end of the cam drive rod 59, allowing the stepper motor to drive the cam drive rod 59 to rotate on the bearing seats.
[0031] As attached Figure 2 As shown, the movable support part includes a fixed support 3 fixedly mounted on the workbench 1, a movable slide bar 4 horizontally mounted on the fixed support 3, and a movable slider 5 horizontally slidably mounted on the movable slide bar 4.
[0032] As attached Figure 2The diagram shows the overall layout of the moving part and the moving support part, specifically as follows: a moving support rod 6 is vertically fixed on the worktable 1; a moving rotating rod 7 is rotatably mounted on the moving support rod 6 at the middle position; a moving drive rod 8 is connected to one end of the moving rotating rod 7 via a fisheye bearing; a moving reset rod 9 is fixed on the worktable 1; the other end of the moving drive rod 8 is connected to the moving slider 5 via a fisheye bearing; the other end of the moving rotating rod 7 is in contact with the moving cam 10 via a moving rotating wheel; and the moving slider 5 and the moving reset rod 9 are connected by a moving reset spring 11.
[0033] The working process and principle of the moving part are as follows:
[0034] 1. In the initial state, the first protrusion of the moving cam 10 works to make the moving slider 5 located at the leftmost end of the fixed bracket 3 (above the assembly station), at which time the moving return spring 11 is in the stretched state;
[0035] 2. When the cam drive rod 59 starts to rotate, all the protrusions on the moving cam 10 do not work on the moving rotation. Under the action of the moving return spring 11, the moving slider 5 rotates on the slide rod to the rightmost position (above the cover gripping station assembly). The sliding of the moving slider 5 drives the moving drive rod 8 to move to the right. The moving drive rod 8 will drive the upper end of the moving rotating rod 7 to move to the left, thereby driving the moving rotating rod 7 to rotate on the moving support rod 6. As a result, the lower end of the moving rotating rod 7 will move to the left. As shown in the figure, the moving rotating rod 7 is located to the right of the moving cam 10. Therefore, the moving rotating wheel is in close contact with the moving cam 10.
[0036] 3. As the cam drive rod 59 continues to rotate, the second protrusion on the moving cam 10 works, causing the moving cam 10 to work on the moving wheel, causing the lower end of the rotating rod to move to the right and the upper end to move to the left, pushing the moving drive rod 8 to move to the left, thereby pushing the moving slider 5 to move to the middle position (above the resistance gripping station assembly) and holding it for a period of time;
[0037] 4. As the cam drive rod 59 continues to rotate, the first protrusion begins to work, and in the same way as above, it pushes the movable slider 5 to continue to move to the left. It takes longer to reach the initial position than it does to stay at one end. After the cam drive rod 59 has rotated one revolution, the movable slider 5 is at the leftmost end and will not move during this period.
[0038] 5. As can be seen from the above description, there are two protrusions on the moving cam 10. At the same time, both protrusions need to be kept in place for a period of time during the work process. Therefore, the outer diameter of the two protrusions does not need to be changed for a period of time. It can also be known that the outer diameter of the first protrusion must be larger than the outer diameter of the second protrusion, otherwise it cannot reach the leftmost side.
[0039] As attached Figure 2The diagram shows the overall schematic of the moving part and the gripping part, specifically as follows: a gripping slide bar 12 is slidably disposed inside the moving slider 5; a resistance gripping clamp 13 is slidably disposed at the lower end of the gripping slide bar 12; a pressing block 14 is disposed at the upper end of the gripping slide bar 12; a first gripping reset spring 15 and a second gripping reset spring 16 are sleeved on the gripping slide bar 12; the first gripping reset spring 15 is located between the upper end face of the moving slider 5 and the lower end face of the pressing block 14; the second gripping reset spring 16 is located between the resistance gripping clamp 13 and the limiting piece 17 fixedly disposed on the gripping slide bar 12; the limiting piece 17 is located below the moving slider 5.
[0040] As attached Figure 4 As shown, the clamping assembly part is as follows: a clamping support rod 26 and a clamping rotating support rod 27 are fixedly mounted on the workbench 1; a clamping rotating rod 28 is rotatably mounted on the clamping support rod 26 in the middle; a clamping connecting rod 29 is rotatably mounted on the clamping rotating support rod 27 at one end; a clamping drive rod 30 is connected to the end of the clamping rotating rod 28 at one end via a fisheye bearing and to the two ends of the clamping connecting rod 29 at the other end via a fisheye bearing; a clamping roller 31 is provided at the other end of the clamping connecting rod 29, the clamping roller 31 is located above the gripping component and corresponds to the assembly station position; a clamping rotating wheel 32 is provided at the other end of the clamping rotating rod 28, the clamping rotating wheel 32 is in contact with the clamping cam 33; a clamping reset connecting rod 34 is provided on the clamping rotating support rod 27, and the clamping reset connecting rod 34 is connected to the clamping rotating rod 28 via a clamping reset spring 35.
[0041] The working process and principle of the clamping assembly are as follows:
[0042] 1. When the movable slider 5 is in the assembly station, as the cam drive rod 59 rotates, the protrusion on the clamping cam 33 begins to work. As shown in the attached figure, the clamping roller 32 is located above the clamping cam 33. When the protrusion of the clamping cam 33 works, it lifts one end of the clamping rod 28, thereby pulling down the other end, which causes the clamping drive rod 30 to move down, thereby driving the clamping connecting rod 29 to rotate around one end of the clamping rotating support rod 27, causing the other end of the clamping connecting rod 29 to move down, causing the clamping roller 31 to strike the upper clamping block 14, and causing the gripping slide rod 12 to slide down for assembly. At this time, the clamping return spring 35 is in a stretched state, and the first gripping return spring 15 and the second gripping return spring 16 are both in a compressed state.
[0043] 2. As the cam drive rod 59 continues to rotate, the protrusion of the clamping cam 33 ceases to function. Under the restoring force of the clamping return spring 35, the clamping rod 28 rises towards the end of the clamping drive rod 30, thereby causing the clamping roller 32 at the other end to remain in contact with the clamping cam 33. Simultaneously, the clamping drive rod 30 rises, causing the clamping rod 28 to rise and return to its original position. As for the gripping slide bar 12, it returns to its initial state under the action of the first gripping return spring 15 and the second gripping return spring 16 as the upper clamping block 14 slowly rises.
[0044] As attached Figure 3 As shown, the gripping and pressing part is as follows: a pressing slide 18 fixedly installed in the vertical state of the fixed bracket 3; two ends slidably connected to the gripping and pressing drive plate 19; a gripping and pressing support rod 20 fixedly installed on the worktable 1; a gripping and pressing rotating rod 21 rotatably installed on the pressing support rod in the middle; a gripping and pressing drive rod 22 with one end connected to the gripping and pressing rotating rod 21 through a fisheye bearing and the other end connected to the gripping and pressing drive plate 19 through a fisheye bearing; a pressing drive track groove 23 is provided on the pressing drive plate; the pressing drive plate is located above the limiting piece 17; a gripping and pressing return spring 24 is provided between the gripping and pressing rotating rod 21 and the side wall of the fixed bracket 3; the other end of the gripping and pressing rotating rod 21 contacts the gripping and pressing cam 25 provided on the drive mechanism through the gripping and pressing roller; the gripping and pressing cam 25 rotates synchronously with the moving cam 10.
[0045] The working process and principle of the gripping and pressing part are as follows:
[0046] 1. When the movable slider 5 is located at the resistance gripping station assembly, as the cam drive rod 59 rotates, the protrusion on the gripping pressure cam 25 begins to work. As shown in the attached figure, the gripping pressure roller is located above the gripping pressure cam 25. When the protrusion of the gripping pressure cam 25 works, one end of the gripping pressure rotating rod 21 is lifted, thereby pulling down the other end, which causes the gripping pressure drive rod 22 to move down, thereby driving the gripping pressure drive plate 19 to slide down on the pressing slide 18, so that the lower end face of the pressure drive track groove 23 is stuck on the upper end face of the limiting piece 17, thereby driving the gripping slide rod 12 down to perform gripping. At this time, the gripping pressure return spring 24 is in a stretched state, and the first gripping return spring 15 and the second gripping return spring 16 are both in a compressed state.
[0047] 2. As the cam drive rod 59 continues to rotate, the protrusion on the gripping and pressing cam 25 ceases to function. Under the restoring force of the gripping and pressing return spring 24, the gripping and pressing rotating rod 21 rises towards the gripping and pressing drive plate 19, thereby causing the gripping and pressing roller at the other end to remain in contact with the gripping and pressing cam 25. At the same time, the gripping and pressing drive plate 19 slides upward to reset. As the gripping slide rod 12 slowly rises with the pressing roller 31 of the upper pressing block 14, it resets to its initial state under the action of the first gripping reset spring 15 and the second gripping reset spring 16.
[0048] As attached Figure 6 The diagram shows the cap gripping station, specifically as follows: a cap vibrating machine 36 fixedly mounted on the workbench 1; a cap conveying track 37 mounted on the upper end of the cap vibrating machine 36; a cap receiving bracket 38 fixedly mounted on the workbench 1; a cap slider 39 fixedly mounted on the side of the cap receiving bracket 38; a cap sliding rod 40 slidably mounted inside the cap sliding cover; a cap lifting support block 41 fixedly mounted on the workbench 1; a cap lifting drive rod 42 rotatably mounted on the cap lifting support block 41 at the middle position; and a cap cam 43 rotatably mounted on the cam drive rod 59. One end of the cap lifting drive rod 42 contacts the cap cam 43 via a cap rotating roller, and the other end is located below the cap sliding rod 40. A cap receiving groove 44 is provided on the upper surface of the cap sliding rod 40, and the cap receiving groove 44 corresponds to the front end of the cap conveying track 37.
[0049] Working process and principle of the cover gripping station:
[0050] 1. When the movable slider 5 is located at the resistor cover gripping station assembly, as the cam drive rod 59 rotates, the protrusion on the cover cam 43 begins to work. As shown in the attached figure, the cover rotating roller is located below the cover cam 43. When the protrusion of the cover cam 43 works, it pushes one end of the cover lifting drive rod 42, which is equipped with the cover rotating roller, downward, thereby causing the other end to move upward, thus pushing the cover slider 39 upward and conveying the resistor cover in the cover receiving slot 44 to the resistor gripping clamp 13 at the upper end.
[0051] 2. As the cam drive rod 59 continues to rotate, the protrusion on the cover cam 43 stops working. At this time, the cover slide rod 40 moves downward under the action of vibration and gravity, thereby causing the other end of the cover lifting drive rod 42 to move upward and press against the cover cam 43. After resetting, the cover vibrating machine 36 starts, vibrating the cover in the cover conveying track 37 into the cover receiving groove 44. At this point, a cover reset spring can also be set between the cover slide rod 40 and the worktable 1, which makes the response faster.
[0052] As attached Figure 4 With appendix Figure 5 The diagram shows the resistor gripping station, specifically comprising: a resistor vibrating machine 45 fixedly mounted on the workbench 1; a resistor conveying track 46 mounted on the upper end of the resistor vibrating machine 45; a resistor receiver located at the front end of the resistor conveying track 46; a resistor receiving bracket 47 fixedly mounted on the workbench 1; a fixing block 48 fixedly mounted on the upper end of the support frame; a closed support frame 49 fixedly mounted on the workbench 1; a closed rotating rod 50 rotatably mounted on the closed support frame 49 at one end; a closed drive rod 51 connected to the other end of the closed rotating rod 50 via a fisheye bearing; and a closed... The closing drive block 52 and the closing latch block 53 are located at the other end of the closing drive block 52. The fixed latch block 48 is provided with a guide plate 54 that passes through and slides on the closing latch block 53. The fixed latch block 48 and the closing latch block 53 are provided with a resistor clamping groove 55. The closing latch block 53 and the fixed latch block 48 are provided with a rubber buffer layer 56 to protect the resistor. If the pressure is too high during the clamping process, the resistor will be damaged or deformed. The closing rotating rod 50 is provided with a closing rotating wheel 57 in the middle. The closing rotating wheel 57 is in contact with the closing cam 58 provided on the cam drive rod 59. A closing compression spring is provided between the lower end of the closing rotating rod 50 and the worktable 1.
[0053] Working process and principle of the resistor grasping station:
[0054] 1. When the movable slider 5 is in the resistor gripping position, the gripping pressing part starts to grip the resistor as the cam drive rod 59 rotates.
[0055] 2. After the gripping is completed, the cam drive rod 59 continues to rotate, causing the protrusion on the closing cam 58 to work. As shown in the attached figure, the closing wheel 57 is located to the left of the closing cam 58. During the work, it will push the closing drive rod 51 to the left, thereby causing the closing drive block 52 to rotate. The upper end rotates to the right, thus realizing the separation of the closing block 53 and the fixed block 48 to form a resistor clamping groove 55 with a larger gap. The resistor direct vibration machine 45 vibrates to input the resistor into the gap. At this time, the closing compression spring is in the stretched state.
[0056] 3. As the cam drive rod 59 continues to rotate, the protrusion on the closing cam 58 stops working, and the closing rotating rod 50 is reset under the action of the closing compression spring. This process is repeated, which reduces the gap between the closing block 53 and the fixed block 48 under the action of the guide plate 54, thus clamping the resistor.
[0057] It should also be noted that there is a 60mm resistor holder at the assembly station, which facilitates the placement of resistor sleeves by assembly personnel.
[0058] Overall working process of this invention:
[0059] 1. In the initial state, the resistor gripper 13 is located on the resistor sleeve 60. It can be seen that the first protrusion of the moving cam 10 is working from the beginning. The assembler places the resistor sleeve on the resistor sleeve 60. As the assembler starts the switch 2, the stepper motor drives the cam drive rod 59 to rotate. First, the clamping assembly part starts, and the clamping cam 33 works to press the resistor sleeve on the resistor gripper 13 into the resistor sleeve, completing the assembly.
[0060] 2. Next, the slider 5 moves to the far right under the action of the moving reset spring 11. At this time, the protrusion of the cover cam 43 on the drive rod starts to work, and the cover gripping station starts to start, pushing the resistor cover upward so that the resistor cover is clamped by the resistor gripping clamp 13.
[0061] 3. The cam drive rod 59 continues to rotate, and the second protrusion of the moving cam 10 works to make the moving slide reach above the resistor gripping station and remain there for a period of time;
[0062] 4. The cam drive rod 59 continues to rotate, gripping the protrusion of the pressing cam 25 to start the gripping and pressing part. The details are described above. At this time, the resistor cover and the resistor are tightly fitted and will not fall off.
[0063] 5. As the cam drive rod 59 continues to rotate, the protrusion of the closing cam 58 begins to work, which starts the resistor gripping station and completes the preparation and waiting for the next resistor. Therefore, the work of the closing cam 58 requires the completion of the second protrusion of the moving cam 10.
[0064] 6. Finally, the cam drive rod 59 continues to rotate, moving the first protrusion of the cam 10 to work and return to its initial state.
[0065] As can be seen from the above description of the work process, there are only two parts where human intervention is required: one is controlling the switch, and the other is placing the resistor sleeve on the assembly station. This reduces the output of human labor, and the process is changed from a dual-station to a single-station process. In addition, the overall quality is more stable.
[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
