Description

Technical Field

[0001] The present application relates to the field of vacuum suction tools, and particularly to a suction tool for sucking light strips. Background Art

[0002] A suction tool for sucking a light strip refers to a tool or device specifically designed to conveniently grasp, fix, or move a light strip when installing, disassembling, or adjusting the light strip. The core function of the suction tool is to firmly adsorb the light strip to prevent the light strip from slipping or being damaged during the installation or disassembly process, and use vacuum and the suction head to perform negative pressure adsorption and fixation on the surface of the light strip.

[0003] For example, the combined vacuum suction cup with the publication number CN201784825U has the following deficiencies in actual use:

[0004] In actual use, several vacuum heads of the above patent are uniformly arranged in a vacuum cavity, resulting in the same adsorption pressure at each position. For the surface of some fragile light strips, too large adsorption pressure will cause problems such as damage, material deformation, or surface damage, which makes it impossible to perform independent adjustment in zones when pressure adjustment is required, and at the same time, it is impossible to stably suck a short light strip. Utility Model Content

[0005] In order to improve the problem that the vacuum head cannot be independently adjusted and causes damage to the surface of the light strip, the present application provides a suction tool for sucking a light strip.

[0006] The suction tool for sucking a light strip provided by the present application adopts the following technical solutions:

[0007] A suction tool for sucking a light strip includes a vacuum generator two, a vacuum generator three, and a vacuum generator four that are respectively fixedly arranged at the upper end of the vacuum suction tool housing and communicate with the inner cavity of the vacuum suction tool housing in an array, and the vacuum generator two, the vacuum generator three, and the vacuum generator four have the same structure.

[0008] A plurality of reinforcing columns are equally divided and fixedly arranged at the top of the inner cavity of the vacuum suction tool housing. An annular column fixedly connected to the top of the inner cavity of the vacuum suction tool housing is arranged between two of the reinforcing columns, and a sensor for detecting the light strip is fixedly arranged between the annular column and the housing of the vacuum suction tool housing.

[0009] A sealing cover that abuts against the reinforcing column and the annular column is fixedly provided at the lower end of the vacuum suction tool housing. A sealing ring for sealing is clamped between the lower ends of the reinforcing column, the annular column, and the vacuum suction tool housing and the sealing cover. A vacuum chamber is provided between the sealing cover and the top of the inner cavity of the vacuum suction tool housing. The vacuum chamber is divided into multiple small cavities by multiple reinforcing columns. The multiple small cavities respectively correspond to vacuum generator two, vacuum generator three, and vacuum generator four. A plurality of suction heads for sucking the light strip and communicating with the vacuum chamber are fixedly arranged in an array on the surface of the sealing cover.

[0010] The lower ends of the reinforcing column, the annular column, and the vacuum suction tool housing abut against the upper end surface of the sealing cover.

[0011] By adopting the above technical solution, vacuum generator two, vacuum generator three, and vacuum generator four are independently controlled, so that light strips of different lengths can be adsorbed, increasing the practicability of the device. At the same time, independently adjusting the vacuum pressures of vacuum generator two, vacuum generator three, and vacuum generator four helps to adjust the pressure on different light strips or the fragile surfaces of the light strips to achieve protection.

[0012] Preferably, annular grooves for clamping the sealing ring are provided at the lower ends of the reinforcing column, the annular column, and the vacuum suction tool housing. The depths of the annular grooves of the reinforcing column, the annular column, and the vacuum suction tool housing are the same, but their shapes are different.

[0013] By adopting the above technical solution, the annular grooves limit the sealing ring. At the same time, the lower end of the sealing ring protrudes from the end faces of the lower ends of the reinforcing column, the annular column, and the vacuum suction tool housing, so that the sealing ring deforms under force to effectively seal the gap, effectively increasing the sealing performance of the multiple small cavities.

[0014] Preferably, the size of the lower end of the vacuum suction tool housing is the same as that of the sealing cover.

[0015] By adopting the above technical solution, the same size can increase the aesthetic appearance of the device.

[0016] Preferably, a threaded fixing hole for fixing the sensor is provided between the annular column and the vacuum suction tool housing. The detection end of the sensor is located between two suction heads, and the detection end face of the sensor is located at half of the normal length of the suction head so that the light strip can touch the sensor.

[0017] By adopting the above technical solution, the sensor includes but is not limited to a non-metal proximity sensor. The normal position of the suction head at half of its length can achieve the protection of the sensor while achieving the detection effect. The half position is the junction of the fixed metal end and the rubber head end of the suction head. The user can also set the position according to the actual use situation.

[0018] Preferably, the second vacuum generator includes a vacuum generator body, and a fixing rod is fixedly provided at the upper end of the vacuum generator body.

[0019] By adopting the above technical solution, the fixing rod is connected to an external robotic arm to drive the device to move.

[0020] Preferably, an internal threaded hole for threaded fixation with the vacuum generator body is provided at the upper end of the surface of the vacuum suction cup housing, and the internal threaded hole communicates with the vacuum chamber.

[0021] By adopting the above technical solution, the setting of the internal threaded hole facilitates the maintenance and replacement of the vacuum generator body.

[0022] Preferably, a limiting ring for limiting the end of the vacuum generator body is fixed at the bottom of the internal threaded hole, and a through hole is provided in the middle of the limiting ring.

[0023] By adopting the above technical solution, the setting of the limiting ring can limit the rotation and fixing depth of the vacuum generator body to avoid reducing the volume of the vacuum chamber and affecting the vacuum pressure.

[0024] Preferably, a reinforcing plate is fixedly connected by clamping between the lower ends of the outer sides of the plurality of fixing rods, a plurality of stress holes are provided on the surface of the reinforcing plate, and one end of the sensor penetrates into one of the stress holes.

[0025] By adopting the above technical solution, the setting of the reinforcing plate can connect the second vacuum generator, the third vacuum generator and the fourth vacuum generator to increase the structural stability and protect the wiring end of the sensor at the same time.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Using a plurality of reinforcing columns to divide the vacuum chamber into a plurality of small cavities, and respectively connecting the second vacuum generator, the third vacuum generator and the fourth vacuum generator to the plurality of small cavities in a corresponding manner, so as to realize the independent adjustment of the second vacuum generator, the third vacuum generator and the fourth vacuum generator, and then can be adjusted according to the properties such as the material of the light strip, thereby increasing the protection of the light strip.

[0028] 2. At the same time, the independent adjustment of the second vacuum generator, the third vacuum generator and the fourth vacuum generator can adsorb a shorter light strip, which has stronger practicality compared with the existing vacuum suction cup. It should be noted that the length of the light strip must be greater than the length of a small cavity, so as to ensure that other unabsorbed suction heads do not affect the suction head being sucked. Therefore, when the light strip is of a specified length, this device can suck multiple light strips, which is more flexible and practical than the existing vacuum suction cup.

[0036] The following will be further described in detail with reference to the attached Figures 1 - 4 This application will be further described in detail.

[0037] The embodiment of this application discloses a suction device for sucking a light strip.

[0038] Refer to Figure 1 , Figure 4, A suction device for sucking light belts includes a vacuum generator two 2, a vacuum generator three 3, and a vacuum generator four 4 respectively and fixedly arranged at the upper end of the vacuum suction device housing 1 in an array. The vacuum generator two 2, the vacuum generator three 3, and the vacuum generator four 4 are all communicated with the inner cavity of the vacuum suction device housing 1. The structures and sizes of the vacuum generator two 2, the vacuum generator three 3, and the vacuum generator four 4 are the same. The vacuum generator two 2 includes a vacuum generator main body 21. A fixing rod 22 is fixedly arranged at the upper end of the vacuum generator main body 21. The fixing rod 22 is connected and fixed to an external actuator or intelligent arm to realize the operation of sucking the light belt. An internal threaded hole 10 is opened at the upper end of the surface of the vacuum suction device housing 1. The internal threaded hole 10 is threadedly fixed to the vacuum end of the vacuum generator main body 21. The middle cavity of the internal threaded hole 10 is communicated with the vacuum chamber 12 to realize pumping out the gas inside the vacuum chamber 12 to achieve a negative pressure state. A limiting ring 11 is fixed at the bottom of the internal threaded hole 10. The upper end of the limiting ring 11 abuts against the end of the vacuum generator main body 21 to achieve a limiting effect so that the vacuum generator main body 21 is installed in place. The middle of the limiting ring 11 is provided with a circular through hole. The outer lower ends between multiple fixing rods 22 are inserted and clamped with the stress holes 8 of the reinforcing plate 6. A ring groove matching the stress holes 8 is opened on the surface of the fixing rod 22. A number of through stress holes 8 are arrayed on the surface of the reinforcing plate 6. One end of the sensor 7 is inserted into one of the stress holes 8.

[0039] Among them, the vacuum generator main body 21 is of an existing structure, and its vacuum generation principle will not be described in detail. The sensor 7 is preferably a non-metallic proximity sensor, and the sensor 7 is connected to an external PLC to realize the detection of the light belt.

[0040] The user installs the vacuum generator main body 21 according to the number of internal threaded holes 10 on the surface of the vacuum suction device housing 1, connects the air inlet end of the vacuum generator main body 21 to an external air source, then inserts the fixing rod 22 into the stress holes 8 on the surface of the reinforcing plate 6 and fixes it at the fixed end of the vacuum generator main body 21. The vacuum generator main body 21 can suck the gas inside the vacuum chamber 12 through the through hole in the middle of the limiting ring 11 to achieve a vacuum effect.

[0041] Refer to Figure 1 、 Figure 3 、 Figure 4, at the top of the inner cavity of the vacuum suction tool housing 1, reinforcing columns 15 are integrally formed in equal parts. There are at least two reinforcing columns 15. A vacuum chamber 12 is arranged between two of the reinforcing columns 15 and one side of the inner cavity of the vacuum suction tool housing 1. The vacuum chamber 12 is divided into multiple small cavities by multiple reinforcing columns 15. The multiple small cavities respectively correspond to the second vacuum generator 2, the third vacuum generator 3, and the fourth vacuum generator 4. A vacuum chamber 12 is also arranged between two reinforcing columns 15. An annular column 16 is arranged between two reinforcing columns 15. The upper end of the annular column 16 is fixedly connected to the top of the inner cavity of the vacuum suction tool housing 1. The lower end faces of the annular column 16 and the reinforcing columns 15 are flush with the two side end faces at the lower end of the vacuum suction tool housing 1.

[0042] The multiple arranged reinforcing columns 15 divide the space of the second vacuum generator 2, the third vacuum generator 3, and the fourth vacuum generator 4, enabling the second vacuum generator 2, the third vacuum generator 3, and the fourth vacuum generator 4 to perform suction actions at different vacuum degrees, realizing the independent actions of the second vacuum generator 2, the third vacuum generator 3, and the fourth vacuum generator 4. Furthermore, the second vacuum generator 2, the third vacuum generator 3, and the fourth vacuum generator 4 can work at different or the same vacuum degrees respectively. When sucking the light strip, it has a higher degree of freedom, and the vacuum degrees of the second vacuum generator 2, the third vacuum generator 3, and the fourth vacuum generator 4 can be set separately according to conditions such as the type or material of the light strip.

[0043] Refer to Figure 2 , Figure 4 , a sealing cover 9 is fixedly arranged at the lower end of the vacuum suction tool housing 1. The upper end of the sealing cover 9 abuts against the lower end faces of the reinforcing columns 15 and the annular column 16. The size of the lower end of the vacuum suction tool housing 1 is the same as that of the sealing cover 9, making the appearance of the device more beautiful during assembly. Annular grooves 13 are opened in the reinforcing columns 15, the annular column 16, and the lower end of the vacuum suction tool housing 1. Sealing rings are clamped inside the annular grooves 13. The depths of the annular grooves 13 in the reinforcing columns 15, the annular grooves 13 in the annular column 16, and the annular grooves 13 in the vacuum suction tool housing 1 are the same but their shapes are different. The vacuum chamber 12 is arranged between the sealing cover 9 and the top of the inner cavity of the vacuum suction tool housing 1. A plurality of suction heads 5 are fixedly arranged in an array on the surface of the sealing cover 9. The plurality of suction heads 5 are used to suck the light strip and are communicated with the vacuum chamber 12. The plurality of suction heads 5 are respectively communicated and fixedly arranged in multiple small cavities, facilitating the independent control of the second vacuum generator 2, the third vacuum generator 3, and the fourth vacuum generator 4. Threaded fixing holes 14 are opened between the annular column 16 and the housing of the vacuum suction tool housing 1. The mounting end of the sensor 7 is threadedly fixed to the threaded fixing holes 14. The detection end of the sensor 7 is located between two suction heads 5, and the detection end face of the sensor 7 is located at half of the normal length of the suction head 5 so that the light strip can touch the sensor 7.

[0044] The suction head 5 is preferably a vacuum soft head and is an existing and mature product, and its specific structure will not be described in detail.

[0045] The vacuum generator two 2, the vacuum generator three 3, and the vacuum generator four 4 are respectively ventilated with gas to control their corresponding suction heads 5. The cooperation of multiple reinforcing columns 15 and sealing rings is used to prevent air leakage between each independent small cavity and affect the vacuum degree of the suction head 5 inside other small cavities. At the same time, the annular column 16 provided cooperates with the sealing ring to prevent external air from entering through the threaded fixing hole 14 and the gap between the annular column 16 and the sealing cover 9, which affects the suction of the suction head 5. The suction head 5 is provided with a rubber head that can fit tightly against the surface of the light strip. Subsequently, when the suction head 5 is blocked by the light strip, it will deform and contract, driving the surface of the light strip to approach or closely adhere to the detection end of the sensor 7. When the sensor 7 detects the presence of the light strip, the suction head 5 will firmly suck the light strip to achieve fixation.

[0046] The implementation principle of a suction tool for sucking a light strip in an embodiment of the present application is as follows: The fixing rods 22 of the vacuum generator two 2, the vacuum generator three 3, and the vacuum generator four 4 are respectively connected to an external robotic arm, and then the air sources connected to the vacuum generator two 2, the vacuum generator three 3, and the vacuum generator four 4 are respectively supplied with gas. The pressure of the gas determines the size of the vacuum. Therefore, the user needs to set the vacuum degrees of the vacuum generator two 2, the vacuum generator three 3, and the vacuum generator four 4 according to the characteristics of the light strip material, etc., to avoid damaging the light strip.

[0047] The vacuum generator main body 21 extracts the gas inside the vacuum chamber 12, and at the same time, external gas will enter through the suction head 5 and generate suction. When the suction head 5 is blocked, it cannot extract external air, that is, the light strip is fixed on the suction head 5. At the same time, the multi-section structure setting of this device can also firmly adsorb the light strip when the length of the light strip is insufficient, and maintain a strong adsorption force. It will not be the same as the existing vacuum suction tool, where part of the suction head 5 sucks the light strip and the other part is suspended, resulting in continuous air entry, which affects the effect of vacuum sucking the light strip and makes the light strip sucking unstable.

[0048] In summary, with the above settings, this device can independently adjust the adsorption pressure for a part of the fragile light strip surface without excessive pressure that may cause damage, material deformation, or surface damage. At the same time, it can adsorb shorter light strips without replacing the vacuum suction tool, increasing the practicality of this device.

[0049] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
