Description

Technical Field

[0001] The present invention relates to the technical field of light guide plates, and in particular to a light guide plate suction cup transfer device and a use method thereof. Background Art

[0002] The light guide plate is a light guide device based on optical-grade acrylic / PC sheets, with multiple light guide points (commonly known as dot surfaces) printed on its surface using technologies such as thermal transfer. The working principle of the light guide plate is to absorb the light emitted from the lamp and stay on the surface of the sheet. When the light hits each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly.

[0003] Light guide plates need to be handled and transferred during production and packaging. In the prior art, suction cup manipulators (hereinafter referred to as transfer devices) are mostly used for transfer. The transfer device is composed of a robot arm, a suction cup fixing frame, and multiple groups of suction cups. The suction cups are installed on the suction cup fixing frame in a fixed connection manner. Therefore, the adsorption and grasping range of the existing transfer device is limited. Therefore, when the object to be grasped is large in size or has a unique shape, the existing transfer device cannot play an effective role and cannot meet the use requirements.

[0011] As a preferred solution of the light guide plate suction cup transfer device described in the present invention, there are four groups of support components, each group of support components includes a group of limiting shafts, and the four groups of limiting shafts are respectively arranged at different positions of the corresponding sliding frames, and are not all arranged at the end of the sliding frames, but the distance from the outermost ends of the four groups of support components to the center of the driving component is the same, so the distance from the four groups of adsorption components corresponding to the ends of the four groups of support components to the center of the driving component is the same.

[0012] As a preferred solution of the light guide plate suction cup transfer device described in the present invention, the adsorption assembly includes a connecting frame vertically arranged at the end of the extension rod, a connecting rod vertically inserted under the connecting frame, a suction cup arranged under the connecting rod, and a supporting spring arranged at the top of the connecting rod.

For a light guide plate of a regular shape, such as a circle or a rectangle with a small difference in length and width ratio, the driving motor drives the driving component to rotate, and the rotating driving component drives the four groups of supporting components to extend outward, thereby driving the corresponding adsorption components on each group of supporting components to move outward synchronously, so as to achieve the synchronous and equal-distance distribution position adjustment of the four groups of adsorption components.

The outwardly extended extension rod will change the position of the adsorption component at its outer end, thereby changing the grabbing point of the adsorption component. At this time, the grabbing range composed of the four sets of adsorption component grabbing points can meet the needs of object transfer, adsorption and grabbing work for irregular light guide plates.

[0015] Beneficial effects of the present invention: 1. By setting the driving components, the device can freely adjust the distribution positions of multiple groups of adsorption components at the same time, so as to achieve the purpose of adjusting the adsorption and grasping range of the device, so that the device can be used in the transfer work of adsorbing and grasping light guide plates of different sizes.

[0016] 2.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Example 1 Reference Figures 1 to 8 , which is the first embodiment of the present invention, comprises a light guide plate suction cup transfer device, comprising, The grasping unit 100 includes a robotic arm 101, a driving motor 102 fixedly arranged on one side of the robotic arm 101, a limiting component 103 fixedly connected to the end of the robotic arm 101, a driving component 104 rotatably sleeved on the limiting component 103, four groups of supporting components 105 surroundingly inserted on the limiting component 103, and the inner ends of the supporting components 105 extending upward into the driving component 104, and adsorption components 106 correspondingly arranged at the outer ends of each group of supporting components 105. The robotic arm 101 is a multi-axis controlled manipulator that can drive the entire device to perform transfer work. The limiting component 103, the driving component 104, the supporting component 105 and the adsorption component 106 can all move with the robotic arm 101 through the driving motor 102 fixedly connected to the robotic arm 101.

[0031] A driving gear 102a is provided at the lower end of the driving motor 102, and the edge of the driving gear 102a meshes with the outer edge above the center position of the driving component 104. The driving motor 102 can drive the driving component 104 to rotate through the meshing of the driving gear 102a and the driving component 104.

[0032] Among them, combined Figure 3 The limiting component 103 includes a connecting shaft 103a fixedly connected to the end of the robot arm 101, and the driving component 104 is rotatably sleeved on the connecting shaft 103a, a bottom plate 103b fixedly arranged below the connecting shaft 103a, a limiting piece 103c fixedly connected between the robot arm 101 and the connecting shaft 103a, a group of limiting frames 103d equally divided and surrounding the outer edge of the bottom plate 103b, and a limiting slide groove 103e opened on each group of limiting frames 103d, and the outer end of the limiting slide groove 103e passes through the limiting frame 103d and is connected to the outside.

[0033] During use, the limiting component 103 is fixedly connected to the robot arm 101 through the connecting shaft 103a, and the whole is kept fixed and cannot move independently, while the driving component 104 is limited on the connecting shaft 103a through the bottom plate 103b and the limiting plate 103c at both ends of the connecting shaft 103a, and can only rotate around the connecting shaft 103a, and cannot move vertically on the connecting shaft 103a. The limiting frames 103d in groups of two can limit the two sides of the supporting component 105, and the limiting slide groove 103e to which the supporting component 105 is inserted is only connected to the outside at the outer end, so that the supporting component 105 can only slide outward along the limiting slide groove 103e.

[0034] Further, combined with Figure 3 Four groups of limit frames 103d are arranged in a cross structure around the limit plate 103c. Therefore, from the midpoint of the limit component 103, there are two groups of support components 105 on each side, that is, there are two adsorption components 106 on each side for adsorption and grasping, and the distance between each adjacent group of adsorption components 106 is the same. When contacting with the light guide plate, the force points can be distributed more evenly to avoid damage to the light guide plate.

[0035] Among them, combined Figure 4 The driving component 104 includes a driving disk 104a rotatably sleeved on the connecting shaft 103a, and the driving disk 104a is a disc structure, a spiral structure is provided on the driving disk 104a with a spiral groove 104b, and the inner end of the supporting component 105 extends upward into the spiral groove 104b, and a driven ring 104c is provided above the center position of the driving disk 104a, and the outer ring of the driven ring 104c is meshed with the driving gear 102a.

[0036] During use, through the engagement of the driven ring 104c and the driving gear 102a, the driving motor 102 can drive the driving component 104 to rotate as a whole around the connecting shaft 103a as the axis, and the driving component 104 will change the position of the spiral groove 104b while rotating. At this time, the object located in the spiral groove 104b will be driven by the driven ring 104c to move. Since the spiral groove 104b is a spiral structure, and the spiral structure expands from the inside to the outside, that is, the object sliding along the spiral groove 104b will gradually move away from the center of the driving component 104, and the outer wall of the spiral groove 104b of the spiral structure has an arc, and the inner wall of the arc has guiding and deflection functions.

[0037] Among them, combined Figure 5 and Figure 6The supporting component 105 includes a sliding frame 105a laterally inserted in the limiting sliding groove 103e, an extension rod 105b laterally inserted in the sliding frame 105a, and an adsorption component 106 is fixedly arranged on the outer end of the extension rod 105b, and a limiting shaft 105c is vertically arranged at the inner end of the sliding frame 105a, and the limiting shaft 105c extends upward into the swirl groove 104b.

[0038] During use, the sliding frame 105a is located in the limiting slide groove 103e, and its two sides will be limited by the limiting frame 103d, so it can only slide horizontally along the limiting slide groove 103e, and the extension rod 105b is slidably inserted in the sliding frame 105a, and can slide horizontally in the sliding frame 105a. The limiting shaft 105c is located in the spiral groove 104b, and is limited by the spiral groove 104b. When the limiting shaft 105c lacks limitation, it can slide along the spiral groove 104b, but the lower end of the limiting shaft 105c is fixedly connected to the sliding frame 105a, so the limiting shaft 105c can also only move in the vertical direction following the sliding frame 105a.

[0039] Further, combined with Figure 5 There are four groups of support components 105, each group of support components 105 includes a group of limit shafts 105c, and the four groups of limit shafts 105c are respectively arranged at different positions of the corresponding sliding frame 105a, and are not all arranged at the end of the sliding frame 105a, but the distance from the outermost end of the four groups of support components 105 to the center of the driving component 104 is the same, so the distance from the four groups of adsorption components 106 corresponding to the ends of the four groups of support components 105 to the center of the driving component 104 is the same.

[0040] During use, the limiting shafts 105c of the four groups of supporting parts 105 are all located in the spiral groove 104b, and the spiral groove 104b is a regular spiral structure. When the spiral groove 104b rotates, the thrust received by each group of limiting shafts 105c and the distance moved along the spiral groove 104b are the same, and the distance from the adsorption component 106 at the end of each group of supporting parts 105 to the center of the driving part 104 is also the same. Therefore, when the spiral groove 104b pushes the four groups of supporting parts 105 to move through the limiting shafts 105c, the four groups of supporting parts 105 move outward by the same distance. Therefore, the adsorption and grasping range formed by the adsorption components 106 at the end of the four groups of sliding frames 105a is proportionally enlarged and scaled, thereby meeting the needs of transferring, adsorbing and grasping light guide plates of different sizes and regular shapes (circular light guide plates or rectangular structure light guide plates with a small difference in length and width ratio, etc.).

[0041] In summary, combined Figure 7 and Figure 8When the device is used to transfer the light guide plate, the driving motor 102 drives the driving component 104 to rotate, and the rotating driving component 104 drives the spiral groove 104b to rotate. The spiral groove 104b applies a pulling force to follow its movement and a horizontal outward pushing force to the limiting shaft 105c through its unique inner wall of the threaded structure, and the limiting shaft 105c can only move horizontally with the sliding frame 105a. Therefore, the limiting shaft 105c will release the force from the spiral groove 104b by pushing the sliding frame 105a to move horizontally outward along the limiting groove 103e. It can be seen that the rotation of the driving component 104 can push the supporting component 105 to drive the corresponding adsorption The function of the component 106 to move outward is to achieve the purpose of changing the adsorption point of the adsorption component 106. The four groups of support components 105 synchronously extend outward through their respective limit shafts 105c following the rotation of the driving component 104. Therefore, the adsorption points of the four groups of adsorption components 106 are changed, and the distances after the four groups of adsorption components 106 extend outward are the same. At this time, the adsorption and grasping range composed of the four groups of adsorption components 106 is proportionally enlarged or reduced compared with the adsorption and grasping range in the initial state, which can meet the needs of transferring the adsorption and grasping work of light guide plates of different sizes and regular shapes (circular light guide plates or rectangular structure light guide plates with a small difference in length and width ratio, etc.).

[0042] Example 2 Reference Figure 6 , Fig. 9 and Fig.10 , which is the second embodiment of the present invention, which is different from the first embodiment in that: the support component 105 with an extended length of the support component 105 is independently adjusted, so that the position of each group of adsorption components 106 corresponding to each group of support components 105 can be adjusted individually, thereby enabling the device to meet the requirements of being applied to the transfer work of adsorbing and grasping light guide plates with unique shapes.

[0043] Compared with Example 1, further, combined with Figure 6 The supporting component 105 also includes a knob 105d arranged below the outer end of the sliding frame 105a, a plurality of sets of teeth 105e equally arranged on the side of the extension rod 105b, and the teeth 105e are arranged on the side of the extension rod 105b close to the knob 105d, and an axial gear 105f arranged vertically at the center position of the sliding frame 105a, and the axial gear 105f extends upward into the sliding frame 105a to mesh with the teeth 105e.

[0044] During use, by turning the knob 105d, the knob 105d can push the extension rod 105b located in the sliding frame 105a outward through the engagement of the teeth 105e with the teeth 105e, thereby achieving the function of changing the overall extension length of the support component 105, thereby achieving the purpose of changing the adsorption point position of the adsorption component 106 installed at the end of the support component 105.

[0045] Among them, combined Figure 6 The adsorption assembly 106 includes a connecting frame 106a vertically arranged at the end of the extension rod 105b, a connecting rod 106b vertically inserted under the connecting frame 106a, a suction cup 106c arranged under the connecting rod 106b, and a supporting spring 106d arranged at the top of the connecting rod 106b.

[0046] During use, the support spring 106d uses its own elastic support to always support the connecting rod 106b and the suction cup 106c under the connecting frame 106a. When the adsorption component 106 abuts against the light guide plate for adsorption, the support spring 106d can absorb the reverse force of the suction cup 106c and the connecting rod 106b in contact with the light guide plate, thereby avoiding the problem of excessive squeezing of the light guide plate by the lower end of the adsorption component 106 and causing damage to the light guide plate, thereby achieving the purpose of buffering protection.

[0047] There are four groups of adsorption components 106, and each group of adsorption components 106 is connected to a group of connecting tubes 107. The ends of the connecting tubes 107 are connected to an air pump, and the air pump can be used to control the suction cup 106c to adsorb or release.

[0048] In summary, when the present device is used to perform transfer work such as adsorption and grasping of a rectangular or arc-shaped structure with a unique shape and a large difference in the length-to-width ratio of a light guide plate, the overall length of the two sets of relative position support components 105 is adjusted separately, and the corresponding knobs 105d on the two sets of support components 105 are rotated. The knob 105d can drive the extension rod 105b to extend outward from the sliding frame 105a through the engagement of the shaft gear 105f and the tooth 105e. The outwardly extended extension rod 105b will change the position of the adsorption component 106 at its outer end, thereby changing the grabbing point of the adsorption component 106. At this time, the horizontal adsorption point position of the device changes, and the vertical position remains unchanged temporarily. At this time, the ratio of the distance between the horizontal adsorption points of the device to the distance between the vertical adsorption points is quite different, as shown in the specific example. Fig. 9 As shown, at this time, the grasping range formed by the grasping points of the four groups of adsorption components 106 of the device can meet the needs of transferring, adsorbing and grasping the rectangular light guide plate with a large difference in length and width ratio; When the arc-shaped light guide plate is adsorbed and grasped, the overall length of the two groups of relative position support components 105 are also adjusted separately. The specific extension length is adjusted according to the size of the arc-shaped light guide plate, so that the two groups of support components 105 in the horizontal direction drive their respective adsorption components 106 to move, so as to achieve the purpose of changing the adsorption points in the horizontal direction, and make the two groups of adsorption points in the horizontal direction respectively located on both sides of the arc of the arc-shaped light guide plate, distinguished by the midpoint of the arc structure of the arc-shaped light guide plate, adjust the extension length of the support components 105 in the vertical direction, and then change the adsorption points of the adsorption components 106 in the vertical direction. At this time, the adsorption points on both sides and the adsorption points in the vertical direction are combined. Fig.10 As shown, by confirming an arc line through three points, it can be known that the device at this time meets the requirements for transferring, adsorbing and grasping the curved light guide plate.

[0049] The remaining structures are the same as those of Example 1.

[0050] Example 3 This is the third embodiment of the present invention. This embodiment includes a method for using a light guide plate suction cup transfer device, comprising the following steps: S1. Confirm the shape and size of the light guide plate to be transferred, select different adjustment methods, and adjust the grabbing range of the grabbing unit 100 by proportional adjustment for the light guide plate with regular shape, and adjust the adsorption grabbing range of the grabbing unit 100 by independent adjustment for the light guide plate with irregular shape; S2. For a light guide plate of a regular shape, such as a circle or a rectangle with a small difference in length and width ratio, the driving motor 102 drives the driving component 104 to rotate, and the rotating driving component 104 drives the four groups of supporting components 105 to extend outward, thereby driving the corresponding adsorption components 106 on each group of supporting components 105 to move outward synchronously, so as to achieve the synchronous and distance-distributed position adjustment of the four groups of adsorption components 106. At this time, the grasping range composed of the four groups of adsorption components 106 is proportionally enlarged or reduced compared with the grasping range of the initial state, thereby meeting the demand for transfer adsorption and grasping of the regular light guide plate; S3. For irregularly shaped light guide plates, such as rectangles or arcs with a large difference in length-to-width ratio, adjust the two groups of relative positions of support components 105 separately, turn the knob 105d, and the knob 105d can drive the extension rod 105b to extend outward from the sliding frame 105a through the engagement of the shaft gear 105f and the tooth 105e. The outwardly extended extension rod 105b will change the position of the adsorption component 106 at its outer end, thereby changing the grabbing point of the adsorption component 106. At this time, the grabbing range composed of the four groups of adsorption components 106 grabbing points can meet the needs of transfer, adsorption and grabbing of irregular light guide plates.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

The light guide plate suction cup transfer device according to claim 6, characterized in that: There are four groups of support components (105), each group of support components (105) includes a group of limit shafts (105c), and the four groups of limit shafts (105c) are respectively arranged at different positions of the corresponding sliding frame (105a), and are not all arranged at the end of the sliding frame (105a), but the distances from the outermost ends of the four groups of support components (105) to the center of the driving component (104) are the same, so the distances from the four groups of adsorption components (106) corresponding to the ends of the four groups of support components (105) to the center of the driving component (104) are the same.

8. The light guide plate suction cup transfer device according to claim 1, characterized in that: The adsorption assembly (106) comprises a connecting frame (106a) vertically arranged at the end of the extension rod (105b), a connecting rod (106b) vertically plugged into the bottom of the connecting frame (106a), a suction cup (106c) arranged below the connecting rod (106b), and a supporting spring (106d) arranged at the top of the connecting rod (106b).

9. The light guide plate suction cup transfer device according to claim 8, characterized in that: There are four groups of adsorption components (106) in total, and each group of adsorption components (106) is connected to a group of connecting pipes (107), and the ends of the connecting pipes (107) are connected to the air pump.

10. A method for using the light guide plate suction cup transfer device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Confirm the shape and size of the light guide plate to be transferred, select different adjustment methods, and use a proportional adjustment method to adjust the grabbing range of the grabbing unit (100) for a light guide plate with a regular shape, and use an independent adjustment method to adjust the adsorption grabbing range of the grabbing unit (100) for a light guide plate with an irregular shape; S2. For a light guide plate of a regular shape, such as a circle or a rectangle with a similar length-to-width ratio, the driving motor (102) drives the driving component (104) to rotate, and the rotating driving component (104) drives the four groups of supporting components (105) to extend outward, thereby driving the corresponding adsorption components (106) on each group of supporting components (105) to move outward synchronously, thereby achieving synchronous and distance-distributed position adjustment of the four groups of adsorption components (106). At this time, the grasping range formed by the four groups of adsorption components (106) is proportionally enlarged or reduced compared to the grasping range in the initial state, thereby meeting the requirements for transfer adsorption grasping of the regular light guide plate; S3. For irregularly shaped light guide plates, such as rectangles with a large difference in length-to-width ratio, the two groups of supporting components (105) are adjusted separately in relative position, and the knob (105d) is turned. The knob (105d) can drive the extension rod (105b) to extend outward from the sliding frame (105a) through the engagement of the shaft gear (105f) and the teeth (105e). The extension rod (105b) extending outward will change the position of the adsorption component (106) at its outer end, thereby changing the gripping point of the adsorption component (106). At this time, the gripping range composed of the gripping points of the four groups of adsorption components (106) can meet the requirements of object transfer, adsorption and gripping work for irregular light guide plates.
