Description

Technical Field

[0001] The present invention belongs to the technical field of positioning and picking up glue, and specifically relates to a precise positioning and picking up glue mechanism. Background Art

[0002] During the process of product processing, sometimes it is necessary to attach a film to a product. When attaching the film, a film carrier and a product processing table are usually used. During the production, transportation, and processing of the film, the film carrier plays a crucial role. It can effectively fix the film, prevent contamination, and improve production efficiency. When in use, the film carrier can ensure that the film is accurately positioned during placement and processing, and can effectively protect the film from scratches, contamination, and other physical damages. The product processing table is used to position and fix the product to which the film is to be attached to avoid deviation of the product during film attachment. Therefore, a precise positioning and picking up glue mechanism is needed.

[0003] The existing precise positioning and picking up glue mechanism has certain drawbacks when in use. When the existing precise positioning and picking up glue mechanism is in use, it usually uses a clamping mechanism to clamp the film on the film carrier and then attach it to the product. Since the structure of the film is usually a long and narrow flexible structure, when the clamping mechanism clamps the film, the clamping force is uneven or the clamping point position is improper, which easily causes the film to bend and deform, so that it cannot be accurately attached to the product. Moreover, when using the clamping mechanism, if the clamping force is too large, it may tear or scratch the film, resulting in waste products, while if the clamping force is too small, the film may fall off during transportation, causing economic losses to people, thus reducing the use effect of the precise positioning and picking up glue mechanism and failing to meet people's needs. Summary of the Invention

The cooperation of the positioning column and the positioning hole accurately transfers the clamped film above the product processing table to achieve precise attachment. The clamping structure and the adsorption structure cooperate to separate the film from the adsorption strip for the next operation. Through the synergistic effect of the clamping assembly, it is ensured that the film can achieve high-precision positioning in each link, reducing the time of manual intervention and adjustment, accelerating the production rhythm. The consistent positioning and fixing method makes the processing process of each film the same, ensuring the stability of product quality and reducing the rejection rate caused by inaccurate positioning or insecure fixing.

[0021] (2) Through the cleaning assembly provided in the present invention, when the adsorption cavity forms a negative pressure cavity, the moving structure can control the connecting frame and the connecting rod to drive the cleaning rod to move in the adsorption hole, so that the buffer structure drives the filtering structure to move out of the adsorption hole, enabling the adsorption hole to adsorb and fix the film. When the adsorption cavity returns to normal pressure, the moving part and the connecting frame move downward under the action of gravity. The first buffer spring and the third buffer spring cooperate to make the cleaning rod move up and down. The buffer part, the second buffer block, the second guiding rod, and the second buffer spring control the filtering block to move up and down in the adsorption hole to clean the impurities in the adsorption hole, thereby improving the adsorption effect of the adsorption structure. The filtering block knocks on the film to separate the film from the adsorption strip and make the film adhere more firmly to the product. The entire adsorption fixation and cleaning process does not require manual intervention, improving production efficiency and being able to thoroughly clean the impurities in the adsorption hole, ensuring the adsorption effect and the quality of the film. The synergistic work between the structures is stable and reliable, reducing the probability of failures. Description of the Drawings

[0034] Embodiment 1

[0035] Please refer to Figure 1 - Figure 6 , this application provides a precise positioning glue picking and placing mechanism, including: a film carrier 1 and a product processing table 2 for placing the film to be adhered. A number of groups of films are equidistantly placed on the film carrier 1, including a positioning structure 3 capable of adjusting the position and a clamping assembly detachably installed on the positioning structure 3 and used for fixing the film. The positioning structure 3 adjusts the position through an externally connected robotic arm, so as to be able to transfer the position of the film fixed by the clamping assembly, thereby picking and placing the film; in the present invention, the clamping assembly includes a number of groups of clamping structures 4 symmetrically arranged on the positioning structure 3 and used for clamping and limiting the film, and an adsorption structure 5 arranged on the clamping structure 4 and used for adsorbing and fixing the film.

[0036] In the present invention, the positioning structure 3 can be externally connected to a robotic arm for transferring the film. The positioning structure 3 includes a connecting frame 6 connected to the robotic arm and positioning seats 7 symmetrically installed on the connecting frame 6. The connecting frame 6 has an "I" - shaped structure. The two ends of the connecting frame 6 are connected to the positioning seats 7. An installation structure for detachably fixing the positioning seats 7 is arranged on the connecting frame 6. Symmetrically arranged positioning columns 8 aligned and connected to the product processing table 2 are arranged at the lower end of the positioning seats 7. A first buffer block 9 elastically connected to the product processing table 2 is sleeved outside the positioning columns 8. The upper end surface of the first buffer block 9 is connected to the lower end surface of the positioning seat 7.

[0037] In the present invention, the installation structure includes an installation block 10 detachably connected to the connecting frame 6 and an installation rod 11 arranged on the installation block 10.

First grooves for the clamping blocks 14 to work are arranged on both the positioning seat 7 and the clamping seat 13. A number of groups of placement blocks for placing the film are arranged on the film carrier 1.

[0039] In the present invention, the adsorption structure 5 includes a number of adsorption cavities 16 formed at the upper end of the clamping seat 13 and a number of adsorption strips 17 detachably installed at the lower end of the clamping seat 13 for adsorbing and limiting the film. A number of adsorption holes 18 communicating with the adsorption cavities 16 are equidistantly arranged on the adsorption strips 17. The positioning seat 7 is hermetically connected to the clamping seat 13. The inner walls of the adsorption cavities 16 and the adsorption holes 18 are both designed to be smooth. An air extraction device for adsorbing and fixing the film through the adsorption cavities 16 and the adsorption holes 18 is externally connected to the positioning seat 7. A number of air extraction through holes connected to the air extraction device are arranged at the upper end of the positioning seat 7. The adsorption cavities 16 are hermetically connected to the positioning seat 7. When the air extraction device extracts air, the internal space of the adsorption cavity 16 can be formed into a negative pressure cavity, so that the adsorption strip 17 adsorbs and fixes the film through the adsorption holes 18. When the air extraction device restores the adsorption cavity 16 to normal pressure, the adsorption strip 17 and the adsorption holes 18 do not adsorb the film.

[0040] In the present invention, a number of adsorption grooves for placing the film are formed on the adsorption strip 17. Clamping blocks 14 are respectively arranged on both sides of the adsorption strip 17 and are provided with second grooves fitting the adsorption strip 17. Clamping grooves corresponding to the film are formed on the clamping blocks 14. Both ends of the clamping blocks 14 are in contact with the outer wall of the film.

[0041] On the outer sides of both ends of the product processing table 2 and on the outer sides of both ends of the film carrier 1 in the present invention, positioning strips 41 aligned with the positioning posts 8 are provided. A number of positioning holes 42 aligned with the positioning posts 8 are equidistantly arranged on the positioning strips 41. The surface of the film carrier 1 is coated with a non-stick layer. A number of films are aligned and placed in parallel on the film carrier 1. The positioning posts 8 are inserted into the positioning holes 42 on the positioning strips 41, so that the clamping structure 4 clamps and fixes the aligned films on the film carrier 1.

[0042] In summary, connect the connecting frame 6 to the robotic arm. The robotic arm moves the clamping structure 4 to directly above the film carrier 1 through the positioning structure 3. Insert the positioning posts 8 into the positioning holes 42, so that the first buffer block 9 is connected to the positioning strip 41, and the positioning seat 7 aligns the clamping seat 13 with the film. Start the driving structure 15 to drive the clamping blocks 14 to move, so that the clamping blocks 14 clamp and fix the film. Start the air extraction device to form a negative pressure cavity in the adsorption cavity 16, so that the adsorption strip 17 adsorbs and fixes the film through the adsorption holes 18. The robotic arm transports the clamped film above the product processing table 2 to align the film with the product. Insert the positioning posts 8 into the positioning strips 41 at both ends of the product processing table 2, attach the film to the product. Start the driving structure 15 to loosen the clamping of the film by the clamping blocks 14. Restore the adsorption cavity 16 to normal pressure through the air extraction device, so that the adsorption holes 18 do not adsorb the film, and separate the film from the adsorption strip 17.

[0043] Example Two

[0044] Refer to Figure 1 and Figure 7 - Figure 10 This is the second embodiment of the present invention. In the present invention, a cleaning component for cleaning the adsorption holes 18 is movably installed in the adsorption cavity 16, and the cleaning component can prevent the adsorption holes 18 from sucking external impurities into the adsorption cavity 16 and causing blockage of the adsorption holes 18.

[0045] In the present invention, the cleaning component includes several groups of cleaning structures 19 aligned with the adsorption holes 18 and movably arranged in the adsorption holes 18, and a moving structure 20 arranged in the adsorption cavity 16 to move the cleaning structures 19 up and down. When the adsorption cavity 16 forms a negative pressure cavity, the moving structure 20 drives the cleaning structure 19 to move upward to open the adsorption holes 18, so that the adsorption holes 18 adsorb the film. When the adsorption cavity 16 returns to normal pressure, the cleaning structure 19 closes the adsorption holes 18.

[0046] In the present invention, the cleaning structure 19 includes a cleaning rod 21 movably arranged in the adsorption hole 18 and a filtering structure 22 movably connected to the bottom end of the cleaning rod 21. The filtering structure 22 can reduce the entry of external impurities into the adsorption hole 18. A number of groups of buffer structures 23 connected to the filtering structure 22 are arranged at the bottom end of the cleaning rod 21. The outer wall of the filtering structure 22 fits with the inner wall of the adsorption hole 18, and several groups of buffer structures 23 are arranged in a circular array on the cleaning rod 21.

[0047] In the present invention, the filtering structure 22 includes a filtering block 24 that fits with the adsorption hole 18 and a filter net 25 detachably installed in the filtering block 24. A through groove for fixing the filter net 25 is formed in the filtering block 24, and the filter net 25 is arranged in the middle of the through groove. The lower end of the filtering block 24 is made of a flexible material to protect the film. The filtering block 24 can knock the adsorbed film when the air extraction device is closed to prevent the film from being adsorbed and adhered to the adsorption strip 17 and unable to be separated.

[0048] In the present invention, the moving structure 20 includes moving parts 26 symmetrically and movably arranged in the adsorption cavity 16 to drive the cleaning rod 21 to lift and lower, and several groups of first buffer springs 27 detachably installed on the inner bottom surface of the adsorption cavity 16 and fitting with the lower end surface of the moving parts 26. The lower end of the first buffer spring 27 is fixed to the adsorption cavity 16, and the upper end of the first buffer spring 27 is not connected to the moving parts 26. The moving parts 26 are arranged in a hollow structure and are made of a lightweight material. Several groups of first guide rods 28 for guiding the movement of the moving parts 26 are vertically installed in the adsorption cavity 16. Several groups of first guide holes corresponding to the first guide rods 28 are formed in the moving parts 26. The first buffer spring 27 is sleeved on the first guide rod 28, and a connection structure 29 fixed to the cleaning structure 19 is arranged on the moving parts 26.

[0049] In the present invention, the buffer structure 23 includes several groups of buffer members 30 vertically installed on the cleaning rod 21 and a second buffer block 31 movably arranged in the buffer members 30 and detachably fixed to the filter block 24. Both the buffer members 30 and the second buffer block 31 can be set as arc-shaped bar structures. Several groups of second buffer springs 32 connected to the second buffer block 31 are detachably installed in the buffer members 30. The two ends of the second buffer spring 32 are respectively connected to the buffer members 30 and the second buffer block 31. A second guide rod 33 for guiding and limiting the second buffer block 31 is vertically arranged in the buffer members 30. Several groups of second guide holes matching the second guide rod 33 are opened at the upper end of the second buffer block 31. The second buffer spring 32 is sleeved on the second guide rod 33. A protrusion connected to the buffer members 30 is arranged on the second buffer block 31. When the cleaning rod 21 drives the filter block 24 to move through the buffer members 30, the second buffer block 31 moves inside the buffer members 30, the second guide rod 33 moves in the second guide holes, and the second buffer spring 32 controls the movement of the second buffer block 31 in the buffer members 30, so as to drive the filter block 24 to vibrate up and down through the second buffer block 31, clean the impurities in the adsorption holes 18, clean the impurities adhered to the filter block 24, and when the filter block 24 moves downward, it can contact the film, thereby separating the film from the adsorption strip 17.

[0050] In the present invention, the connection structure 29 includes a connection frame 34 connected to the moving member 26 and several groups of connecting rods 35 vertically installed on the outer wall of the cleaning rod 21 and detachably fixed to the inner wall of the connection frame 34. The cleaning structure 19 is aligned and arranged inside the connection frame 34. A rectangular through groove is opened on the connection frame 34. The connection frame 34 is made of a lightweight material. Several groups of guiding structures 36 for guiding the lifting of the connection frame 34 are arranged inside the connection frame 34.

[0051] In the present invention, the guiding structure 36 includes several groups of third guide rods 37 vertically arranged in the adsorption cavity 16 and a third guide block 38 movably sleeved on the third guide rods 37 and connected to the inner wall of the connection frame 34. A third buffer spring 39 that fits the lower end of the third guide block 38 is sleeved on the third guide rods 37. A buffer strip 40 connected to the bottom end of the third guide rod 37 is aligned and arranged on the inner bottom surface of the adsorption cavity 16. The lower end of the third buffer spring 39 is fixedly connected to the buffer strip 40, and the lower end of the third buffer spring 39 is not fixedly connected to the third guide block 38. The buffer strip 40 can prevent the third guide block 38 from contacting the adsorption cavity 16.

[0052] In summary, when the air extraction device is started and the adsorption cavity 16 is formed into a negative pressure cavity, the moving part 26 moves upward along the first guide rod 28. The moving part 26 drives the cleaning rod 21 to move upward through the connecting frame 34 and the connecting rod 35, so that the connecting frame 34 drives the third guide block 38 to move on the third guide rod 37, and the cleaning rod 21 moves the filtering structure 22 out of the adsorption hole 18 through the buffer structure 23, enabling the adsorption hole 18 to adsorb and fix the film. When the air extraction device is closed and the adsorption cavity 16 returns to normal pressure, the moving part 26 and the connecting frame 34 move downward under the action of gravity. The moving part 26 contacts the first buffer spring 27 and moves up and down. The connecting frame 34 contacts the third buffer spring 39 through the third guide block 38 and moves up and down, thereby driving the cleaning rod 21 to move up and down. The cleaning rod 21 drives the second buffer block 31 to move up and down through the buffer member 30, enabling the second buffer spring 32 and the second buffer block 31 to cooperate to control the filtering block 24 to move up and down in the adsorption hole 18, cleaning the impurities in the adsorption hole 18, and causing the filtering block 24 to strike the film, separating the film from the adsorption strip 17 and attaching the film to the product more firmly.

[0053] Embodiment 3

[0054] Referring to Figure 1 - Figure 10 this embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0055] The positioning structure 3 is aligned with the film carrier 1 through the cooperation of the positioning post 8 and the positioning hole 42. The driving structure 15 and the clamping block 14 cooperate to clamp and fix the film. The adsorption cavity 16, the adsorption strip 17 and the adsorption hole 18 adsorb and fix the film. The positioning post 8 accurately transfers the clamped film above the product processing table 2 to achieve precise attachment. The clamping structure 4 and the adsorption structure 5 cooperate to separate the film from the adsorption strip 17 for the next round of operation. Through the synergistic effect of the clamping components, it is ensured that the film can achieve high-precision positioning in each link, reducing the time for manual intervention and adjustment, accelerating the production rhythm. The consistent positioning and fixing method makes the processing process of each film the same, ensuring the stability of product quality and reducing the rejection rate caused by inaccurate positioning or insecure fixing. When the adsorption chamber 16 is formed into a negative pressure chamber, the moving structure 20 can control the connecting frame 34 and the connecting rod 35 to drive the cleaning rod 21 to move in the adsorption hole 18, so that the buffer structure 23 drives the filtering structure 22 to move out of the adsorption hole 18, so that the adsorption hole 18 adsorbs and fixes the film. When the adsorption chamber 16 is restored to normal pressure, the moving part 26 and the connecting frame 34 move downward under the action of gravity, and the first buffer spring 27 and the third buffer spring 39 cooperate to make the cleaning rod 21 move up and down. The buffer part 30, the second buffer block 31, the second guide rod 33 and the second buffer spring 32 control the filter block 24 to move up and down in the adsorption hole 18, clean the impurities in the adsorption hole 18, and the filter block 24 knocks on the film to separate the film from the adsorption strip 17. The whole adsorption fixing and cleaning process does not require manual intervention, improves the production efficiency, can thoroughly clean the impurities in the adsorption hole, ensures the adsorption effect and the film quality, the cooperative work between the structures is stable and reliable, and reduces the probability of failure.

[0056] The above embodiments are only used to illustrate the technical method 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 of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
