Description

Technical Field

[0001] The present invention relates to the technical field of production and processing tooling, and particularly to a rapid tooling device for touch panels. Background Art

[0002] In the field of touch panel production, precise positioning and adjustment are key process steps. Existing touch panel tooling generally fixes the touch panel by driving it to translate on carriers such as negative pressure suction plates, but there are significant technical bottlenecks: First, the negative pressure residue in the carrier pipeline will enhance the adsorption force, significantly increasing the frictional resistance between the touch panel and the carrier. To complete the position adjustment, a greater driving force needs to be applied, which directly causes problems such as edge cracking and circuit damage of the touch panel (especially for curved screens and ultra-thin screens) due to uneven stress, affecting the product yield.

[0003] Second, the negative pressure suction plate has a high adsorption force. However, the moving resistance brought by the high adsorption force will prolong the positioning time of the touch panel, and additional cycles are required to overcome the resistance in an automated production line, resulting in a decrease in the single-machine production capacity.

[0004] The applicant believes that the touch panel tooling in the prior art has at least the following technical problems: 1. The negative pressure residue in the carrier pipeline of the existing touch panel tooling will increase the frictional resistance between the touch panel and the carrier, posing a risk of touch panel damage; 2. For the existing touch panel tooling, due to the high adsorption force of the negative pressure suction plate, it will bring certain moving resistance, prolong the positioning time of the touch panel, and affect the adjustment efficiency and production capacity. Summary of the Invention

[0005] The present invention discloses a rapid tooling device for touch panels to solve the technical problem that the negative pressure residue in the carrier pipeline of the touch panel tooling in the prior art will increase the frictional resistance between the touch panel and the carrier, posing a risk of touch panel damage.

[0006] To solve the above problems, the present invention adopts the following technical solutions: In a first aspect, the present application provides a rapid tooling device for touch panels, including a fixed table and a controller; the fixed table includes a first adsorption component and a second adsorption component; wherein, The first adsorption component has a first adsorption area, and a plurality of first negative pressure nozzles for adsorbing the touch panel are provided on the first adsorption area. The first negative pressure nozzles are connected to a negative pressure source through a first negative pressure pipeline; The second adsorption component has a second adsorption area, and a plurality of second negative pressure nozzles for adsorbing the touch panel are provided on the second adsorption area. The second negative pressure nozzles are connected to the negative pressure source through a second negative pressure pipeline, and the second adsorption area is disposed around the outside of the first adsorption area; The first adsorption component is arranged on the second adsorption component in a liftable and rotatable manner; The first adsorption component and the second adsorption component are respectively electrically connected to a controller.

[0007] The technical solution adopted by the present invention can achieve the following beneficial effects: For the touch panel quick tooling device provided in this application, the way to fix the touch panel is as follows: In the initial state, the height of the first negative pressure nozzle is higher than that of the second negative pressure nozzle. First, the first adsorption component is controlled by the controller to adsorb the touch panel, and the touch panel is locked by the first negative pressure nozzle. At this time, the second negative pressure nozzle remains closed through the elastic reset mechanism; then, the direction of the touch panel is adjusted. Since the first adsorption component can rotate relative to the second adsorption component, the direction of the touch panel can be adjusted by driving the touch panel to rotate through the first adsorption component until the adjustment is in place; since the first adsorption component can lift relative to the second adsorption component, the controller controls the first adsorption component to descend. When the first adsorption component descends to a preset height (at this time, the touch panel contacts the second negative pressure nozzle), the locking of the touch panel by the first adsorption component is released, and the first negative pressure nozzle will descend to a height lower than that of the second negative pressure nozzle. The second negative pressure nozzle automatically opens under the gravity of the touch panel, overcoming the elastic resistance of the elastic reset mechanism, and switches to the second state. At this time, the touch panel can be locked by the second negative pressure nozzle, and multi-point attraction fixation can be achieved to ensure fixation stability. The touch panel quick tooling device provided in this application can avoid problems such as cracking and circuit damage of the touch panel edge caused by the need to apply a greater driving force to overcome the frictional resistance with the carrier, can improve the product yield, and can improve the positioning efficiency and production capacity.

[0011] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0012] As Figures 1 - 15 shown: Embodiment 1: This application provides a quick tooling device for a touch control panel, including a fixed table and a controller; the fixed table includes a first adsorption component and a second adsorption component; wherein, The first adsorption component has a first adsorption area 1, and a plurality of first negative pressure nozzles 2 for adsorbing the touch control panel 34 are arranged on the first adsorption area 1, and the first negative pressure nozzles 2 are connected to a negative pressure source through a first negative pressure pipeline 27; The second adsorption component has a second adsorption area 3, and a plurality of second negative pressure nozzles 4 for adsorbing the touch control panel 34 are arranged on the second adsorption area 3, and the second negative pressure nozzles 4 are connected to the negative pressure source through a second negative pressure pipeline, and the second adsorption area 3 is arranged around the outside of the first adsorption area 1; The first adsorption component is arranged on the second adsorption component in a liftable and rotatable manner; The first adsorption component and the second adsorption component are respectively electrically connected to the controller.

[0013] In some embodiments, the first adsorption component and the second adsorption component have a cooperative working mode: First state: The height of the first negative pressure nozzle 2 is higher than that of the second negative pressure nozzle 4. The touch panel 34 is locked by the first negative pressure nozzle 2, and the second negative pressure nozzle 4 is kept closed by the elastic reset mechanism. Second state: The first negative pressure nozzle 2 descends to a height lower than that of the second negative pressure nozzle 4. The second negative pressure nozzle 4 automatically opens under the gravity of the touch panel 34, overcoming the elastic resistance of the elastic reset mechanism, and the touch panel 34 is locked by the second negative pressure nozzle 4. It can be understood that in the first state, only the first negative pressure nozzle 2 is in contact with the touch panel 34. The height of the first negative pressure nozzle 2 is higher than that of the second negative pressure nozzle 4, and the second adsorption component is completely disengaged, which can eliminate the peripheral frictional resistance. Moreover, by driving the touch panel 34 to rotate through the first adsorption component to adjust the direction of the touch panel 34, it is also not necessary to overcome the frictional resistance with the carrier and apply a greater driving force. In the second state, the second negative pressure nozzle 4 is in contact with the bottom of the touch panel 34 through the elastic reset mechanism, and the gravity of the touch panel 34 is used to automatically trigger the opening of the second negative pressure nozzle 4, so that the touch panel 34 can be adsorbed by the second adsorption component.

[0014] In some embodiments, the first adsorption component includes a first adsorption body. The top of the first adsorption body is the first adsorption area 1 of the touch panel 34. The first negative pressure nozzle 2 is arranged on the first adsorption body. A first negative pressure cavity 5 communicated with the first negative pressure nozzle 2 is provided in the first adsorption body, and the first negative pressure pipeline 27 is communicated with the first negative pressure cavity 5.

[0015] In some embodiments, the first adsorption component is arranged on the second adsorption component through a liftable component; the liftable component includes a first sleeve 6, a second sleeve 7, an electromagnet 8 and a permanent magnet 9; wherein, The permanent magnet 9 is arranged on the lower side of the first adsorption body; The electromagnet 8 is arranged on the second adsorption body and is located below the permanent magnet 9; the electromagnet 8 is electrically connected to the controller; The first sleeve 6 is connected to the lower side of the first adsorption body. The second sleeve 7 is slidably sleeved on the outside of the first sleeve 6. A sealing structure is arranged between the first sleeve 6 and the second sleeve 7. The second sleeve 7 is connected to one end of the first negative pressure pipeline 27 through a coupling 30, and the other end of the first negative pressure pipeline 27 is connected with a quick-release joint 28 for connecting to an external negative pressure source. Among them, when the electromagnet 8 is energized, it generates a magnetic field opposite to that of the permanent magnet 9, thereby driving the permanent magnet 9 to drive the first adsorption body to move in a direction away from the electromagnet 8. It can be understood that non-contact driving is achieved through the interaction of the magnetic fields of the electromagnet 8 and the permanent magnet 9, realizing the lifting of the first adsorption assembly. Non-contact transmission can avoid mechanical wear; the first sleeve 6 and the second sleeve 7 are in sliding fit, and a sealing structure is provided. The sleeve structure provides guidance and sealing, and can cooperate to realize the lifting of the first adsorption assembly, while ensuring the sealing of the first negative pressure pipeline 27 in the first adsorption assembly, ensuring a stable lifting process without air leakage.

[0016] In some embodiments, a first limiting boss 31 is provided on the inner wall of the top end of the second sleeve 7, and a second limiting boss 32 is provided on the outer wall of the bottom end of the first sleeve 6; when the electromagnet 8 is energized, the permanent magnet 9 drives the first adsorption body to move in a direction away from the electromagnet 8 until the first limiting boss 31 abuts against the second limiting boss 32 to form a limiting connection. It can be understood that the provided first limiting boss 31 and the second limiting boss 32 are a limiting connection structure, and the maximum lifting stroke of the first adsorption assembly is limited by the physical limiting structure, preventing component collision and damage caused by excessive driving of the electromagnet 8, and ensuring the position consistency during the switching of the adsorption state.

[0017] In some embodiments, at least one O-ring seal is provided in the overlapping section of the first sleeve 6 and the second sleeve 7, and the material is selected as wear-resistant and high-temperature-resistant fluororubber; the seal ring is embedded in the annular groove on the outer wall of the first sleeve 6, and dynamic sealing is achieved by the extrusion of the inner wall of the second sleeve 7.

[0018] In some embodiments, the second negative pressure pipeline includes a negative pressure main pipe 10, a plurality of negative pressure sub-pipes 11 connected to the negative pressure main pipe 10, and a plurality of negative pressure branch pipes 12 connected to each negative pressure sub-pipe 11. Each second negative pressure nozzle 4 is correspondingly connected to a negative pressure branch pipe 12. It can be understood that the tree-shaped pipeline structure of the negative pressure main pipe 10, the negative pressure sub-pipes 11 and the negative pressure branch pipes 12 is mainly to achieve precise distribution and independent control of the adsorption force. The negative pressure main pipe 10 provides a stable negative pressure source, the negative pressure sub-pipes 11 are branched by region, and the negative pressure branch pipes 12 correspond to a single second negative pressure nozzle 4. By controlling the on-off of the negative pressure sub-pipes 11, the adsorption area of different products can be quickly switched, saving the time for parameter adjustment compared with the traditional full-pipeline adsorption, and supporting the rapid changeover production of multi-size touch panels 34.

[0019] In some embodiments, the second adsorption assembly includes a second adsorption body. The top of the second adsorption body is the second adsorption area 3 of the touchpad 34. The second negative pressure nozzle 4 is provided on the second adsorption body. A thixotropic cavity 13 is provided in the second adsorption body corresponding to each second negative pressure nozzle 4, and the elastic reset mechanism is arranged in the thixotropic cavity 13. The elastic reset mechanism includes a gravity sealing ball 14, an elastic reset component, and a linkage transmission component. Among them, The elastic reset component includes a thixotropic rod 15 slidably arranged in the thixotropic cavity 13, and one end of the thixotropic rod 15 extends outside the second negative pressure nozzle 4. A sealing ring 16 adapted to the second negative pressure nozzle 4 is provided at the position of the thixotropic rod 15 corresponding to the second negative pressure nozzle 4. A rib 17 is provided on the outer wall of the thixotropic rod 15, and a sliding groove 26 adapted to the rib 17 is correspondingly opened on the second adsorption body. An elastic member 18 is arranged in the sliding groove 26, and both ends of the elastic member 18 are fixedly connected to the rib 17 and the second adsorption body respectively. The linkage transmission component includes a first fixed pulley 19 and a second fixed pulley 20 symmetrically arranged on both sides of the rib 17, and a third fixed pulley 21 installed on the gravity sealing ball 14. The first fixed pulley 19, the second fixed pulley 20, and the third fixed pulley 21 form a closed-loop transmission structure through a tension belt 22. The gravity sealing ball 14 is located above the air suction port 33 of the negative pressure branch pipe 12. In the first state, the gravity sealing ball 14 closes the air suction port 33 under the action of gravity, and the sealing ring 16 closes the second negative pressure nozzle 4 under the elastic force of the elastic member 18; when the touchpad 34 presses on the second negative pressure nozzle 4, the thixotropic rod 15 compresses the elastic member 18 and moves downward, and the convex strip 17 drives the tension belt 22 to drive the third fixed pulley 21 to move upward, and the gravity sealing ball 14 moves with the third fixed pulley 21 to open the air suction port 33, switching to the second state. It can be understood that the composite structure of the gravity sealing ball 14, the elastic reset assembly and the linkage transmission assembly is mainly to achieve the full-automatic switching of the adsorption state and the pressure self-adaptation. The traditional mechanical valve relies on air pressure or motor drive for switching, which has problems of response delay and complex structure. This design uses the self-gravity of the touchpad 34 as the triggering power, drives the tension belt 22 through the downward movement of the thixotropic rod 15, and synchronously opens the air suction port 33 by the gravity sealing ball 14 without an additional power source; at the same time, the elastic member 18 provides a reset force to ensure reliable sealing under the non-load state, and solves the problem of adsorption force superposition caused by negative pressure residue. This design has a short state switching time, a switching rate higher than that of the traditional mechanical valve, and zero power consumption; the double sealing of the gravity sealing ball 14 and the sealing ring 16 reduces the leakage rate, ensures that the second adsorption component does not intervene at all in the first state, and avoids interfering with the direction adjustment accuracy; realizes the improvement of switching efficiency and reliability. Moreover, the elastic member 18 can adapt to touchpads 34 of different weights by replacing springs with different stiffnesses, without modifying the mechanical structure, can realize the mixed-line production of touchpad 34 products of multiple models, reduce the number of tooling models, and has a wide application range.

[0020] In some embodiments, the cross-section of the sealing ring 16 is circular, and the cross-sectional area of the sealing ring 16 gradually increases from top to bottom. It can be understood that the design of the circular sealing ring 16 with a narrow upper part and a wide lower part mainly takes into account both the sealing performance and the mechanical limiting function. On the one hand, the second negative pressure nozzle 4 needs to achieve reliable sealing in the non-working state to prevent negative pressure leakage from affecting the adsorption effect; on the other hand, when the thixotropic rod 15 rises under the drive of the electromagnet 8, there needs to be a clear limiting structure to avoid excessive displacement resulting in component damage or function failure. The structure with a narrow upper part and a wide lower part enables the sealing ring 16 to not only closely fit the nozzle to achieve efficient sealing, but also provide a rigid stop when the thixotropic rod 15 rises to the limit position. The circular sealing ring 16 with a narrow upper part and a wide lower part realizes the double optimization of sealing and limiting: in terms of the sealing effect, the conical structure makes the contact area between the sealing ring 16 and the second negative pressure nozzle 4 increase with the increase of pressure, reduces the leakage rate in the negative pressure environment, and ensures zero interference in the second adsorption area 3 when the first adsorption component works; in terms of mechanical limiting, it can accurately limit the rising stroke of the thixotropic rod 15, avoid the failure of the elastic member 18 or the misalignment of the gravity sealing ball 14 caused by excessive rising, and improve the reliability of the mechanism.

[0021] In some embodiments, the touchpad quick tooling device includes four support legs 25 provided at the bottom of the second adsorption body.

[0022] In some embodiments, a pipeline layout cavity 38 for laying a negative pressure sub-pipeline 11 and a negative pressure branch pipe 12 is further provided in the second adsorption body.

[0023] In some embodiments, the convex strips 17 are arranged along the radial direction of the thixotropic rod 15, and the number of the convex strips 17 is N, where N≥2 and N is a natural number; the N convex strips 17 are equally angularly spaced along the circumferential direction of the thixotropic rod 15, and each convex strip 17 is located at the same axial height. It can be understood that the setting of multiple equally angularly distributed convex strips 17 is to ensure that the thixotropic rod 15 can maintain uniform circumferential force when moving under force, and to avoid tilting and jamming of the thixotropic rod 15 caused by uneven force, which affects the normal operation of the elastic reset mechanism; at the same time, the multiple convex strips 17 can disperse the acting force of the tension belt 22, preventing damage caused by excessive stress at a single contact point. It can make the thixotropic rod 15 move more smoothly, reduce the risk of jamming, ensure the precise cooperation between the gravity seal ball 14 and the air suction port 33, and between the sealing ring 16 and the second negative pressure nozzle 4, improve the success rate of state switching, and effectively improve the stability and reliability of the adsorption assembly.

[0024] In some embodiments, the value range of N is 2≤N≤4 (preferably N = 2).

[0025] In some embodiments, the cross-sectional shape of the convex strip 17 is any one of a rectangle, a trapezoid or a semi-circle.

[0026] In some embodiments, a friction enhancement layer is provided on the contact surface between the tension belt 22 and the convex strip 17. It can be understood that the transmission between the tension belt 22 and the convex strip 17 relies on friction, and slippage may occur between the two during the working process, resulting in the gravity seal ball 14 being unable to be opened or reset in time, affecting the state switching of the adsorption assembly. The setting of the friction enhancement layer can increase the friction force and ensure the accuracy and reliability of the transmission.

[0027] In some embodiments, the touchpad quick tooling device further includes a direction adjustment component for adjusting the direction of the touchpad 34. The direction adjustment component includes a first direction adjustment component 23 and a second direction adjustment component 24 that are perpendicularly arranged; wherein, The first direction adjustment component 23 includes a first driving mechanism 2301 and a first pushing member connected to the first driving mechanism 2301. The first pushing member has a first pushing surface 39 adapted to the side shape of the touchpad 34; a first pressure sensor 29 and a second pressure sensor 35 are provided on the first pushing surface 39; the first pressure sensor 29 and the second pressure sensor 35 are respectively electrically connected to the controller; The second direction adjustment component 24 includes a second driving mechanism 2401 and a second pushing member connected to the second driving mechanism 2401. The second pushing member has a second pushing surface 40 adapted to the side shape of the touchpad 34. A third pressure sensor 36 and a fourth pressure sensor 37 are provided on the second pushing surface 40. The third pressure sensor 36 and the fourth pressure sensor 37 are respectively electrically connected to the controller. The heights of the first pushing surface 39 and the second pushing surface 40 are both matched with the installation height when the touchpad 34 is adsorbed on the first adsorption component. The first driving mechanism 2301 and the second driving mechanism 2401 are respectively electrically connected to the controller.

[0028] It can be understood that, for example, a rectangular touchpad 34 has a first side 3401 and a second side 3402 that are perpendicular to each other. During its processing, precise positioning and adjustment are required in two mutually perpendicular directions to meet the position accuracy requirements of different processing technologies. The direction adjustment component is split into a first direction adjustment component 23 and a second direction adjustment component 24 with a vertical design, corresponding to the first side 3401 and the second side 3402 of the touchpad 34 respectively, which can achieve independent control of the two directions. High-precision positioning and adjustment of the touchpad 34 in the two-dimensional plane are realized, greatly improving the accuracy of assembling the touchpad 34 with other components, increasing the yield rate of the product, and at the same time meeting the requirements of various high-precision processing technologies such as bonding and cutting. The controller can be configured as: a) When the difference between the detection values of the first pressure sensor 29 and the second pressure sensor 35 is less than the threshold A, control the first driving mechanism 2301 to stop advancing, where 1N ≤ A ≤ 10N; b) When the difference between the detection values of the third pressure sensor 36 and the fourth pressure sensor 37 is less than the threshold B, control the second driving mechanism 2401 to stop advancing, where 1N ≤ B ≤ 10N; c) Calculate the assembly position coordinates of the touchpad 34 according to the final extended length of the first pushing member and the final extended length of the second pushing member. It can be understood that the thresholds A and B are used to quantify the allowable force deviation on both sides, and their values need to be set according to the size, material, and test requirements of the touchpad 34 (for example, 1 - 5N can be taken for small-size screens, and 5 - 10N can be taken for large-size screens) to ensure that the deviation is within the range that does not affect the test results or assembly accuracy.

[0029] The rectangular touchpad 34 has a first side 3401 and a second side 3402 that are perpendicular to each other. Taking the rectangular touchpad 34 as an example, the adjustment method of the direction adjustment component is described below: During use, first adjust the direction of the first side 3401 (or the second side 3402) of the touchpad 34 using the first-direction adjustment component 23 (or the second-direction adjustment component 24), that is, select one side to position the touchpad 34 in one direction, and then use the second-direction adjustment component 24 (or the first-direction adjustment component 23) to position the entire touchpad 34. The following takes the case of first adjusting the direction of the first side 3401 of the touchpad 34 using the first-direction adjustment component 23 and then positioning the touchpad 34 through the second-direction adjustment component 24 to illustrate the method for adjusting the direction of the touchpad 34.

[0030] Please refer to Figure 14 (a)、 Figure 14 (b)、 Figure 14 (c): S1. Drive the first pusher of the first drive mechanism 2301 to reset to the zero position, and drive the second pusher of the second drive mechanism 2401 to reset to the zero position; S2. Adsorb the touchpad 34 on the first adsorption area 1 of the first adsorption component. At this time, lock the touchpad 34 through the first negative pressure nozzle 2. The initial position is as shown in Figure 14 Figure (a); S3. As shown in Figure 14 Figure (b), the first drive mechanism 2301 drives the first push rod 2302 to extend along the direction of arrow a, and the first flexible plate 2304 pushes the touchpad 34 to rotate along the direction of arrow b; when the difference between the detection values of the first pressure sensor 29 and the second pressure sensor 35 is less than the threshold A, the controller controls the first drive mechanism 2301 to stop advancing, completing the position adjustment in the first direction, and the extension length of the first push rod 2302 can be obtained; S4. The second drive mechanism 2401 drives the second push rod 2402 to extend along the direction of arrow c in Figure 14 Figure (c). When the difference between the detection values of the third pressure sensor 36 and the fourth pressure sensor 37 on the second flexible plate 2404 is less than the threshold B, the controller controls the second drive mechanism 2401 to stop advancing, and the extension length of the second push rod 2402 can be obtained, completing the positioning of the touchpad 34, as shown in Figure 14 Figure (c); Finally, calculate the assembly position coordinates of the touchpad 34 by combining the extension lengths of the first push rod 2302 and the second push rod 2402, and the position of the touchpad 34 on the tooling can be accurately obtained, achieving high-precision positioning and meeting the strict requirements for position accuracy in the processing of the touchpad 34.

[0031] In some embodiments, the first pusher includes a first push rod 2302 and a first push plate 2303. One end of the first push rod 2302 is connected to a first driving mechanism 2301, and the other end of the first push rod 2302 is connected to the first push plate 2303. The plane where the first push plate 2303 is located is parallel to the first side surface 3401 of the touch panel 34. A first flexible plate 2304 having a first pushing surface 39 is provided on the first push plate 2303. The second pusher includes a second push rod 2402 and a second push plate 2403. One end of the second push rod 2402 is connected to a second driving mechanism 2401, and the other end of the second push rod 2402 is connected to the second push plate 2403. The plane where the second push plate 2403 is located is parallel to the second side surface 3402 of the touch panel 34. A second flexible plate 2404 having a second pushing surface 40 is provided on the second push plate 2403. It can be understood that the flexible plate has elastic deformation characteristics. When pushing the touch panel 34, it can effectively buffer the impact force brought by rigid contact, and avoid the edge cracking or surface damage of the touch panel 34 caused by excessive force. The combination of the push rod and the push plate provides a stable support and driving structure for the flexible plate, ensuring that the flexible plate can accurately transmit the driving force to the touch panel 34. Through the buffering of the flexible plate, the impact force on the touch panel 34 during the pushing process is reduced, effectively protecting the touch panel 34. Especially for the ultra-thin touch panel 34, the edge cracking rate of the touch panel 34 can be effectively reduced.

[0032] In the touch panel quick tooling device provided in the embodiment of the present application, the usage method of fixing the touch panel 34 is as follows: In the first state, the height of the first negative pressure nozzle 2 is higher than the height of the second negative pressure nozzle 4. First, the first adsorption component is controlled by the controller to adsorb the touch panel 34, and the touch panel 34 is locked by the first negative pressure nozzle 2. At this time, the second negative pressure nozzle 4 is kept closed by the elastic reset mechanism. Then, the controller controls the direction adjustment component to adjust the direction of the touch panel 34. Since the first adsorption component can rotate relative to the second adsorption component, the direction of the touch panel 34 can be adjusted by driving the touch panel 34 to rotate through the first adsorption component. After the adjustment is in place, the controller controls the direction adjustment component to slightly retract. The controller controls the first adsorption component to descend. When the first adsorption component descends to a preset height (at this time, the touch panel 34 contacts the second negative pressure nozzle 4), the locking of the touch panel 34 by the first adsorption component is released, and the first negative pressure nozzle 2 will descend to a height lower than that of the second negative pressure nozzle 4. The second negative pressure nozzle 4 automatically opens under the action of the gravity of the touch panel 34, overcoming the elastic resistance of the elastic reset mechanism, and switches to the second state. At this time, the touch panel 34 can be locked by the second negative pressure nozzle 4. Finally, the controller controls the direction adjustment component to retract, as Figure 15 shown, it can reduce the processing space limitation brought by the first push plate 2303 and the second push plate 2403.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
