Description

Technical Field

[0001] This utility model relates to the field of bonding machine technology, specifically to a visual bonding machine with adsorption positioning. Background Technology

[0002] Automated placement machines, as key pieces of equipment, are designed to achieve high-speed, high-precision placement of two workpieces. Existing automated bonding machines typically include a conveying device, a dispensing device, a loading device, a vision positioning device, and a bonding device. In operation, the conveying device first transports the first workpiece to the dispensing device for adhesive application. After adhesive application, the conveying device then transports the adhesive-coated first workpiece to the bonding station; simultaneously, the vision positioning device acquires the actual position information of the first workpiece at the bonding station. On the other hand, the loading device transports the second workpiece to the fixture limiting groove at the loading station, achieving positioning of the second workpiece through physical limiting. Finally, the bonding device, based on the position information acquired by the vision positioning device, transfers the second workpiece from the limiting groove to the bonding station, aligning and pressing it with the adhesive-coated first workpiece. By continuously repeating the above operation process, the automated bonding machine can achieve continuous batch bonding production of two workpieces, significantly improving production efficiency.

[0003] As can be seen from the working process of the existing automatic laminating machine, it determines the positions of the first and second workpieces respectively through a vision positioning device and a limiting groove before performing the lamination operation. This positioning design effectively ensures lamination accuracy. However, when switching to laminating workpieces of other specifications or types, since the size and shape of the limiting groove are fixed, the machine must be stopped to replace the fixture with one of the corresponding limiting groove size and shape to ensure accurate positioning of the second workpiece during loading. This operation is not only cumbersome and complex, requiring a significant amount of time and manpower, but frequent downtime also severely impacts production efficiency. Furthermore, improper operation during fixture replacement may introduce new errors, potentially affecting product quality.

[0004] Given the aforementioned limitations in workpiece positioning design of existing automatic pick-and-place machines, it is particularly important to develop a vision-based pick-and-place machine with adsorption positioning to meet diversified production needs and achieve rapid switching and efficient bonding of workpieces of different specifications or types.

Finally, based on the detection results of the first and second detection devices, the bonding device picks up the second workpiece on the transfer table and moves it toward the adhesive-coated first workpiece. At the same time, it adjusts the position of the second workpiece so that the positions of the second workpiece and the adhesive-coated first workpiece are opposite and can completely overlap. Then, the second workpiece and the adhesive-coated first workpiece are bonded together. As can be seen, this utility model uses an adsorption fixture to adsorb and position the first workpiece. Compared with the traditional positioning method of limiting groove, it can adapt to the first workpiece of different specifications or types. Furthermore, the transfer table can carry the second workpiece of different specifications or types. Therefore, this utility model can be used to bond the first and second workpieces of different specifications or types, which significantly improves the versatility of the equipment.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] This invention provides a vision-based patch machine with adsorption positioning, which addresses the issues of improving production flexibility and efficiency while ensuring bonding accuracy.

[0051] See Figure 1 and Figure 2 As shown, Figure 1This is a top view of the vision-based patching machine with adsorption positioning in the embodiment. Figure 2 The following is a perspective view of the conveyor line, adsorption fixture, first feeding device, dispensing device, second feeding device and bonding device in the embodiment. The vision patching machine with adsorption positioning includes a frame 1, a conveyor line 2, several adsorption fixtures 3, a first feeding device 4, a first detection device 5, a dispensing device 6, a second feeding device 7, a second detection device 8 and a bonding device 9.

[0052] The frame 1 includes a transfer table 11 for placing the second workpiece b.

[0053] The conveyor line 2 is installed on the frame 1, and the adsorption fixture 3 is installed on the conveyor line 2. The conveyor line 2 is used to transport the adsorption fixture 3, and the adsorption fixture 3 is used to adsorb and position the first workpiece a.

[0054] The first feeding device 4, the first detection device 5, the dispensing device 6, the second feeding device 7, the second detection device 8, and the bonding device 9 are all mounted on the frame 1. The first feeding device 4, the dispensing device 6, the second feeding device 7, and the bonding device 9 are arranged sequentially along the conveying direction of the conveyor line 2. The first detection device 5 is located above the conveyor line 2, and the second detection device 8 is located above the transfer table 11.

[0055] The first feeding device 4 is used to transport the first workpiece a one by one to the adsorption fixture 3; the first detection device 5 is used to detect the position of the first workpiece a on the adsorption fixture 3; the dispensing device 6 is used to apply glue to the first workpiece a on the adsorption fixture 3; the second detection device 8 is used to detect the position of the second workpiece b on the transfer table 11; the second feeding device 7 is used to transport the second workpiece b one by one to the transfer table 11; and the bonding device 9 is used to grab the second workpiece b on the transfer table 11 according to the detection results of the first detection device 5 and the second detection device 8, and align and press it onto the glued first workpiece a on the adsorption fixture 3.

[0056] When using the above-described adsorption-positioning vision patching machine, firstly, the first feeding device 4 transports the first workpiece a one by one to the adsorption fixtures 3 on the conveyor line 2. The first detection device 5 detects the position of the first workpiece a on the adsorption fixture 3. At the same time, the second feeding device 7 transports the second workpiece b one by one to the transfer table 11. The second detection device 8 detects the position of the second workpiece b on the transfer table 11. Then, the conveyor line 2 transports the first workpiece a to the area below the dispensing device 6, where the dispensing device 6 applies adhesive to the first workpiece a. After application, the conveyor line 2 transports the adhesive-coated first workpiece a to the area below the bonding device 9. Finally, based on the detection results of the first detection device 5 and the second detection device 8, the bonding device 9 picks up the second workpiece b on the transfer table 11 and moves it toward the adhesive-coated first workpiece a. At the same time, it adjusts the position of the second workpiece b so that the positions of the second workpiece b and the adhesive-coated first workpiece a are opposite and can completely overlap. Then, the second workpiece b and the adhesive-coated first workpiece a are bonded together. As can be seen, this utility model uses the adsorption fixture 3 to adsorb and position the first workpiece a. Compared with the traditional positioning method of limiting groove, it can adapt to the first workpiece a of different specifications or types. Moreover, the transfer table 11 can carry the second workpiece b of different specifications or types. Therefore, this utility model can be used to bond the first workpiece a and the second workpiece b of different specifications or types, which significantly improves the versatility of the equipment. The equipment can quickly switch to bonding tasks of other specifications or types of workpieces without stopping the machine for adjustment, which effectively improves the flexibility and overall efficiency of production and meets diversified production needs.

[0057] Furthermore, this utility model can obtain the loading positions of the first workpiece a and the second workpiece b through the first detection device 5 and the second detection device 8 respectively, and then adjust the position of the second workpiece b according to the obtained position information to ensure that the positions of the first workpiece a and the second workpiece b are completely overlapped, thereby ensuring the fitting accuracy of the second workpiece b and the first workpiece a.

[0058] The aforementioned conveyor line 2 can use any one of the existing indexing plates, motor-conveyor belt mechanisms, motor-conveyor chain mechanisms, motor-roller conveyor line 2, or transplanting mechanisms, or a combination of more than one of these conveyor mechanisms.

[0059] The aforementioned dispensing device 6 can use existing dispensing equipment, and existing three-axis moving mechanisms or robotic arms or other automated equipment can be installed between the dispensing device 6 and the frame 1. This allows the dispensing device 6 to move relative to the conveyor line 2, enabling it to apply adhesive to any position of the first workpiece a on the conveyor line 2. Figure 1 and Figure 2 As shown.

[0060] The first detection device 5 and the second detection device 8 mentioned above can use existing CCD cameras, which can quickly and accurately acquire the position information of the workpiece.

[0061] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 3 This is a perspective view of the conveyor line, adsorption fixture, second feeding device, bonding device, and unloading device in the embodiment. In one embodiment of the bonding device 9, the bonding device 9 includes a negative pressure suction cup 91, a transfer mechanism 92, and a rotating mechanism 93. The negative pressure suction cup 91 is connected to an external vacuum adsorption device (not shown in the figure) and is used to adsorb or release the second workpiece b. The transfer mechanism 92 is mounted on the frame 1 by means of screwing or welding, and the rotating mechanism 93 is mounted on the output end of the transfer mechanism 92 by means of screwing or welding, and is connected to the negative pressure suction cup 91 in a transmission manner. The transfer mechanism 92 is used to drive the rotating mechanism 93 and the negative pressure suction cup 91 to reciprocate between the transfer table 11 and the conveyor line 2. The rotating mechanism 93 is used to drive the negative pressure suction cup 91 to rotate a certain angle. Thus, when the bonding device 9 is used, firstly, the transfer mechanism 92 and the negative pressure suction cup 91 work together to grip the second workpiece b on the transfer table 11 and move it toward the corresponding glued first workpiece a on the conveyor line 2. Simultaneously, the rotation mechanism 93, based on the detection results of the first detection device 5 and the second detection device 8, drives the negative pressure suction cup 91 to rotate at a certain angle so that the positions of the second workpiece b and the glued first workpiece a completely overlap. Finally, the transfer mechanism 92 and the negative pressure suction cup 91 work together to press down on the second workpiece b, thus bonding the completely overlapping second workpiece b and the glued first workpiece a into one piece. It can be seen that the bonding device 9, through the coordinated operation of the rotation mechanism 93, the first detection device 5, and the second detection device 8, can precisely control the bonding position of the second workpiece b and the glued first workpiece a, laying a solid foundation for subsequent high-quality bonding, effectively avoiding bonding defects caused by positional deviations, and greatly improving the product yield.

[0062] The aforementioned transfer mechanism 92 can use existing three-axis moving mechanisms or automated equipment such as robotic arms to drive the rotating mechanism 93 and the negative pressure suction cup 91 to any position. The aforementioned rotating mechanism 93 can use existing rotary motor-pulley or other rotary drive mechanisms, and its output end is connected to the negative pressure suction cup 91 by means of screwing or welding.

[0063] See Figure 2 and Figure 3As shown, in one embodiment of the conveyor line 2 and the adsorption fixture 3, the conveyor line 2 is an indexing plate, and the adsorption fixture 3 includes an adsorption plate 31 and an air pipe connector (not shown in the figure). The adsorption plate 31 is fixed to the indexing plate by means of screwing or welding, and the adsorption plate 31 has multiple air holes 311. The adsorption plate 31 is used to place the first workpiece a and adsorb and fix its position. One end of the air pipe connector is fixed to the bottom of the adsorption plate 31 by means of screwing or welding and communicates with the multiple air holes 311, and the other end is used to connect to an external vacuum adsorption device (not shown in the figure). The air pipe connector is used to provide suction force for the adsorption plate 31 to adsorb the first workpiece a. In this way, by using the indexing plate as the conveyor line 2, precise indexing and conveying can be achieved, ensuring accurate positioning between each station; and the adsorption plate 31 is connected to the external vacuum adsorption device through the air holes 311 and the air pipe connector, which can generate a stable adsorption force, effectively fix the position of the first workpiece a, prevent it from moving during conveying and processing, and improve the bonding accuracy.

[0064] The multiple pores 311 on the adsorption plate 31 can be evenly distributed, which can evenly adsorb the first workpiece a, avoid stress concentration, and thus ensure that the second workpiece b will not be damaged or broken due to adsorption pressure during the transfer and bonding process.

[0065] See Figure 2 and Figure 3 As shown, based on any of the above embodiments, the visual patching machine with adsorption positioning further includes a feeding device 10. The feeding device 10 includes a scraper 101, a scraper drive 102, and a feeding conveyor belt 103. The feeding conveyor belt 103 is mounted on the frame 1 and is used to receive and transport the workpieces that have been bonded on the conveyor line 2. The scraper 101 is located upstream of the feeding conveyor belt 103. The scraper drive 102 is mounted on the frame 1 by means of screwing or welding and is drively connected to the scraper 101. The scraper drive 102 is used to drive the scraper 101 to move along the material-carrying surface 312 of the adsorption fixture 3 toward or away from the feeding conveyor belt 103, so as to move the workpiece placed on the material-carrying surface 312 onto the feeding conveyor belt 103. Thus, the unloading device 10, through the cooperation of scraper 101, scraper drive 102 and unloading conveyor belt 103, can automatically unload and transport the workpieces that have been bonded on the conveyor line 2, so as to free up the adsorption fixture 3, which is convenient for the next round of bonding, and further improves the degree of production automation.

[0066] The aforementioned scraper drive 102 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is connected to the scraper 101 by means of screwing or welding. The aforementioned unloading conveyor belt 103 can use existing conveying mechanisms such as motor-conveyor belt mechanisms or motor-conveyor chain mechanisms.

[0067] See Figure 2 and Figure 3As shown, in one embodiment of the first feeding device 4 and the second feeding device 7, both the first feeding device 4 and the second feeding device 7 include a storage rack 71 and a pushing mechanism 72. The storage rack 71 is installed on one side of the conveyor line 2 or the transfer station 11. The storage rack 71 has a storage space 711 for stacking and accommodating the first workpiece a or the second workpiece b, and the storage rack 71 has a discharge port 712 on the side facing the conveyor line 2 or the transfer station 11. The discharge port 712 communicates with the storage space 711 and is positioned opposite to the bottommost first workpiece a or the second workpiece b in the storage space 711. The pushing mechanism 72 is mounted on the frame 1 by sliding or screwing, etc., and is used to push the bottommost first workpiece a or the second workpiece b in the storage space 711 from the discharge port 712 onto the conveyor line 2 or the transfer station 11. Thus, the first feeding device 4 and the second feeding device 7 can centrally store the first workpiece a or the second workpiece b through the storage rack 71, saving space and facilitating subsequent automatic feeding. The pushing mechanism 72 can automatically push the bottom layer of the first workpiece a or the second workpiece b in the storage space 711 from the discharge port 712 to the conveyor line 2 or the transfer table 11. After the bottom layer of the first workpiece a or the second workpiece b in the storage space 711 is removed, it can automatically move down one layer under its own gravity so that the pushing mechanism 72 can push it again. By repeating this process, the automatic continuous feeding of the first workpiece a or the second workpiece b can be achieved, which greatly improves production efficiency and ensures the feeding sequence and stability.

[0068] See Figure 2 and Figure 3 As shown, in one embodiment of the feeding mechanism 72, the feeding mechanism 72 includes a push plate 721 and a push plate drive member 722. The push plate 721 is positioned opposite to the discharge port 712, and the height of the push plate 721 does not exceed the height of the lowest first workpiece a or second workpiece b in the storage space 711. The push plate drive member 722 is mounted on the frame 1 by means of sliding or screw connection, and is connected to the push plate 721 in a transmission manner. The push plate drive member 722 is used to drive the push plate 721 to move towards or away from the discharge port 712. In this way, the height of the push plate 721 is reasonably designed to ensure that only the lowest first workpiece a or second workpiece b is pushed out, avoiding the upper first workpiece a or second workpiece b from moving out of the discharge port 712 together with the lowest first workpiece a or second workpiece b; while the push plate drive member 722 provides power to realize the automatic reciprocating motion of the push plate 721, complete the feeding action, and improve the feeding accuracy and efficiency.

[0069] The aforementioned push plate drive component 722 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is connected to the push plate 721 by means of screwing or welding.

[0070] See Figure 2 and Figure 3As shown, based on the above embodiment, there are at least two storage spaces 711, and the number of pushing mechanisms 72 and storage spaces 711 are the same, with their positions corresponding one-to-one. Both the storage rack 71 and the pushing mechanism 72 are slidably connected to the frame 1. Both the first feeding device 4 and the second feeding device 7 also include a switching mechanism 73. The switching mechanism 73 is fixed to the frame 1 by screwing or welding, and is drively connected to the storage rack 71 and the pushing mechanism 72, so that each discharge port 712 alternately faces the position of the conveyor line 2 or the transfer table 11. Thus, the multiple independent storage spaces 711 provided by this utility model have dual functional modes: First, they can centrally store the same specification or type of first workpiece a or second workpiece b, forming a large-scale material storage unit. When the current storage space 711 facing the conveyor line 2 or transfer station 11 is short of material, other spare storage spaces 711 can be switched to the conveyor line 2 or transfer station 11 through the switching mechanism 73, ensuring production continuity while facilitating the loading of empty storage spaces 711. Second, each storage space 711 can independently store different specifications and types of first workpiece a or second workpiece b, constructing a modular material supply system. When it is necessary to switch to the bonding task of other specifications or types of workpieces, the outlet 712 of the corresponding storage space 711 can be connected to the conveyor line 2 or transfer station 11 through the switching mechanism 73, so as to quickly switch to the loading of other specifications or types of first workpiece a or second workpiece b. This not only avoids the production interruption caused by specification switching of traditional equipment, but also further improves the equipment's versatility and production flexibility, meeting diversified production needs.

[0071] The aforementioned switching mechanism 73 can use existing linear displacement drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is connected to the storage rack 71 and the pushing mechanism 72 by means of screwing or welding.

[0072] If there is only one storage space 711, the push plate drive component 722 can be directly fixed to the frame 1 by means of screwing or welding.

[0073] See Figure 2 and Figure 3As shown, in one embodiment of the storage rack 71, the storage rack 71 includes a first limiting plate 713, a limiting rod 714, and two second limiting plates 715. The first limiting plate 713 is fixed to the mounting base 731 by welding or screwing, forming a discharge port 712 between the first limiting plate 713 and the mounting base 731. The output end of the switching mechanism 73 is provided with a mounting base 731 by screwing or welding, and the mounting base 731 has a plurality of mounting positions 732. Each mounting position 732 is evenly distributed along the width direction of the first limiting plate 713. The limiting rod 714 is detachably installed on any mounting position 732 of the mounting base 731 and is distributed opposite to the side of the first limiting plate 713 facing away from the conveyor line 2 or the transfer table 11. The two second limiting plates 715 are slidably connected to the mounting base 731 along the length direction of the first limiting plate 713 and are located between the first limiting plate 713 and the limiting rod 714. A locking structure (not shown in the figure) is provided between the second limiting plate 715 and the mounting base 731 to fix the second limiting plate 715 and the mounting base 731. The first limiting plate 713, the limiting rod 714, and the two second limiting plates 715 enclose a storage space 711 adapted to the first workpiece a or the second workpiece b. In this way, the storage rack 71 forms the storage space 711 by enclosing the first limiting plate 713, the limiting rod 714, and the second limiting plate 715, which is simple and stable. In addition, the limiting rod 714 can be detachably installed in different mounting positions 732, and the second limiting plate 715 can be slidably adjusted, so that the size of the storage space 711 can be flexibly adjusted according to the size and shape of the first workpiece a or the second workpiece b actually being processed, thereby improving the adaptability of the equipment; while the locking structure ensures that the adjusted storage space 711 is stable and reliable.

[0074] The aforementioned locking structure can be used to fix the second limiting plate 715 and the mounting base 731 using a damping structure or a bolt and nut structure. The mounting position 732 can be a threaded hole, and the limiting rod 714 can be screwed onto any mounting position 732 for easy adjustment of the position of the limiting rod 714.

[0075] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
