Description

Technical Field

[0001] This utility model relates to the field of automatic adhesive applicator technology, specifically to an anti-sticking feeding mechanism for an adhesive applicator. Background Technology

[0002] Adhesive application equipment is an automated device used to precisely attach various types of tapes, films, protective films, double-sided tapes, and other materials to the surface of products. Its applications are extremely wide-ranging, covering almost all modern manufacturing sectors requiring precise, efficient, and consistent bonding, such as electronic component processing, automotive parts assembly, home appliance manufacturing, and medical device manufacturing.

[0003] The feeding mechanism in automatic adhesive applicator is mainly used to pick up products and place them onto the conveyor belt, realizing automatic feeding of products to be adhesived. Since most products requiring adhesive are sheet-like structures and are typically stacked on the feeding rack before feeding, static electricity inevitably causes them to stick together. Therefore, the problem of static adhesion needs to be addressed during feeding.

[0004] The feeding mechanisms of existing automatic adhesive applicators almost always solve the problem of electrostatic adhesion by shaking the product back and forth after it is picked up. For some small products, this method can solve the problem of electrostatic adhesion. However, for some large products, especially those exceeding 500mm in size, simple shaking is not enough to completely solve the problem of electrostatic adhesion.

[0005] To enable the adhesive application equipment to be suitable for applying adhesive to extra-large products, the feeding mechanism of the existing automatic adhesive application equipment needs to be improved to solve the problem of electrostatic adhesion of products. Utility Model Content

[0006] To address some or all of the problems existing in the prior art, this utility model provides an anti-adhesion feeding mechanism for an adhesive applicator. The adhesive applicator includes a base with a product conveyor belt. The anti-adhesion feeding mechanism includes a feeding base disposed on one side of the base. The feeding base is equipped with a feeding lifting mechanism and a picking robot. The output end of the feeding lifting mechanism is equipped with a discharging lifting plate for stacking products to be processed. The feeding lifting mechanism drives the discharging lifting plate to move up and down. The picking robot is used to grab products from the discharging lifting plate and place them on the product conveyor belt. The output end of the picking robot is equipped with a shaking cylinder and a first picking suction cup, and the output end of the shaking cylinder is equipped with a second picking suction cup. The feeding base is equipped with a first anti-adhesion structure and a second anti-adhesion structure. The first anti-adhesion structure can connect with the side of the product on the discharging lifting plate, and the second anti-adhesion structure is used to blow ionizing air towards the discharging lifting plate.

[0007] As a further improvement of this utility model, the first anti-adhesion structure includes a first mounting frame, which is connected to the feeding base. The first mounting frame is provided with an anti-adhesion brush, which can connect with the product side on the feeding lifting plate.

[0008] As a further improvement of this utility model, the second anti-adhesion structure includes a second mounting frame, on which an ion air bar is provided, the ion air bar being able to blow ion air towards the material feeding lifting plate.

[0009] As a further improvement of this utility model, the feeding lifting mechanism includes a feeding motor, which is connected to the feeding base. A feeding screw is provided on the output end of the feeding motor, and the unloading lifting plate is slidably limited to the feeding screw.

[0010] As a further improvement of this utility model, four lifting guide rods are rectangularly distributed on the feeding lifting plate, and lifting guide sleeves are respectively provided on the feeding base at the corresponding positions of the lifting guide rods. The lifting guide rods pass through the corresponding lifting guide sleeves, and the two are slidably engaged.

[0011] As a further improvement of this utility model, the feeding base is provided with multiple limiting rods, and the feeding lifting plate is provided with limiting holes at corresponding positions of the limiting rods. The limiting rods pass through the corresponding limiting holes, and the limiting rods are adjustablely limited to the feeding base.

[0012] As a further improvement of this utility model, the feeding base is provided with a position sensor, which is used to detect the position of the product at the top of the feeding lifting plate.

[0014] As a further improvement of this utility model, the output end of the material picking lifting cylinder is provided with a suction cup mounting rod, and the suction cup mounting rod is provided with an elongated hole. The first material picking suction cup is adjustablely and limitedly connected to the elongated hole.

[0015] As a further improvement of this utility model, there are two of each of the first and second material-picking suction cups, and the first and second material-picking suction cups are respectively connected to a negative pressure device.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This invention not only retains the shaking-based anti-sticking structure but also adds a first anti-sticking structure and a second anti-sticking structure.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0020] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, an anti-sticking feeding mechanism for an adhesive applicator is used in conjunction with an automatic adhesive applicator. The adhesive applicator includes a base with a product conveyor belt. The anti-sticking feeding mechanism includes a feeding base 1, which is placed on one side of the base. The feeding base 1 is equipped with a feeding lifting mechanism 2 and a picking robot 3. A discharging lifting plate 21 is located at the output end of the feeding lifting mechanism 2. The discharging lifting plate 21 is used to stack products to be processed, and the feeding lifting mechanism 2 drives the discharging lifting plate 21 to move up and down. The picking robot 3 picks up products from the discharging lifting plate 21 and places them onto the product conveyor belt. During processing, the products to be processed are stacked on the discharging lifting plate 21, and the feeding lifting mechanism 2 drives the discharging lifting plate 21 to rise. When the top product on the discharging lifting plate 21 reaches the picking height of the picking robot 3, the picking robot 3 picks up the product from the discharging lifting plate 21 and transfers it onto the product conveyor belt, completing the automatic product feeding process.

[0023] The output end of the material handling robot 3 is equipped with a shaking cylinder 31 and a first material handling suction cup 32, and the output end of the shaking cylinder 31 is equipped with a second material handling suction cup 33. In this embodiment, there are two first material handling suction cups 32 and two second material handling suction cups 33, and each of the first material handling suction cups 32 and the second material handling suction cups 33 is externally connected to a negative pressure device. When the material handling robot 3 is working, by applying negative pressure to the first material handling suction cups 32 and the second material handling suction cups 33, the product at the top of the feeding lifting plate 21 can be adsorbed; then, by driving the two second material handling suction cups 33 to move back and forth, the adsorbed product is subjected to high-frequency, small-amplitude shaking, ensuring that the material handling robot 3 only grabs a single product at a time, reducing the risk of product sticking during feeding.

[0024] To minimize the problem of products sticking together during the feeding process, a first anti-sticking structure 4 and a second anti-sticking structure 5 are provided on the feeding base 1. The first anti-sticking structure 4 can contact the side of the product on the unloading lifting plate 21, and directly acts on the side of the product at a physical level to separate products that may be slightly stuck together. The second anti-sticking structure 5 is used to blow ion air towards the unloading lifting plate 21, eliminating static electricity on the product surface at the source and preventing electrostatic adsorption. This dual action of combining physical and static elimination can extremely effectively solve the problem of electrostatic adhesion of large-sized sheet products, ensuring the single-sheet nature and stable reliability of the feeding process.

[0025] Specifically, such as Figure 3 As shown, the first anti-adhesion structure 4 includes a first mounting bracket 41 fixed to the feeding base 1 by bolts, and an anti-adhesion brush 42 is mounted on the first mounting bracket 41. The tips of the bristles of the anti-adhesion brush 42 lightly touch or come very close to the sides of the product. When the product rises with the feeding lifting plate 21, the sides of the product will rub against the anti-adhesion brush 42, and the bristles can separate the slightly stuck products.

[0026] like Figure 4 As shown, the second anti-adhesion structure 5 includes a second mounting bracket 51 fixed to the feeding base 1 by bolts. An ionizing air bar 52 is mounted on the second mounting bracket 51, and the ionizing air bar 52 can blow ionizing air towards the discharging lifting plate 21. The air outlet of the ionizing air bar 52 faces the product pile on the discharging lifting plate 21. After being energized, the ionizing air bar 52 generates a large number of positive and negative ions, and the resulting ionizing air blows onto the product surface, effectively neutralizing the static electricity carried by the product due to friction, etc., thus preventing the products from adsorbing and sticking together due to static electricity at the source.

[0027] like Figure 1As shown, the feeding lifting mechanism 2 includes a feeding motor 22, which is fixed on the feeding base 1. The output end of the feeding motor 22 is connected to a feeding lead screw 23. The unloading lifting plate 21 is connected to the feeding lead screw 23 via a threaded sleeve or nut, forming a sliding limit connection. The unloading lifting plate 21 is used to stack and place products to be processed. During operation, the feeding motor 22 drives the feeding lead screw 23 to rotate, thereby causing the unloading lifting plate 21 to perform vertical lifting motion.

[0028] To ensure smooth lifting, four lifting guide rods 24 are fixed in a rectangular arrangement on the feeding lifting plate 21, and four lifting guide sleeves 25 are installed at corresponding positions on the loading base 1. The lifting guide rods 24 pass through the corresponding lifting guide sleeves 25 and slide in cooperation with them. The cooperation between the lifting guide rods 24 and the lifting guide sleeves 25 can limit and guide the lifting direction of the feeding lifting plate 21, thereby improving the accuracy of the transmission.

[0029] Multiple limiting rods 6 are vertically installed on the loading base 1. Limiting holes 26 are correspondingly provided on the unloading lifting plate 21, and the upper ends of the limiting rods 6 pass through the corresponding limiting holes 26. The limiting rods 6 are used to limit the position of the product placed on the unloading lifting plate 21. The limiting rods 6 and the loading base 1 are connected in an adjustable manner by means of locking nuts, etc. By adjusting the installation position of the limiting rods 6 on the loading base 1, the product placed on the unloading lifting plate 21 can be positioned to adapt to the processing needs of products of different sizes and improve the versatility of the equipment.

[0030] A position sensor 7 (such as a photoelectric sensor) is installed on the feeding base 1 to detect whether the product at the top of the feeding lifting plate 21 has reached the preset gripping height and to send a signal to the control system. A material shortage sensor 8 is installed on the feeding lifting plate 21 to detect whether there are still products on the plate. When there is a material shortage, an alarm signal is issued to remind the operator to replenish the products in time.

[0031] like Figure 5 As shown, the material handling robot 3 includes a robot arm mounting frame 34, which is fixedly mounted on the loading base 1. A robot arm lateral movement module 35 (which can be a lead screw module or a synchronous belt module) is mounted on the robot arm mounting frame 34. A material handling mounting frame 36 is mounted on the output end of the robot arm lateral movement module 35. A material handling lifting cylinder 37 and a shaking cylinder 31 are mounted on the material handling mounting frame 36. A suction cup mounting rod 38 is connected to the output end of the material handling lifting cylinder 37, and an elongated hole 39 is provided on the suction cup mounting rod 38. Two first material handling suction cups 32 are adjustablely connected to the elongated hole 39 by bolts or other fasteners, allowing the spacing between the two first material handling suction cups 32 to be adjusted according to the product size. By adjusting the position of the first material handling suction cups 32 on the suction cup mounting rod 38, it can be adapted to handle products of different sizes, improving the versatility of the equipment.

[0032] Working principle: The operator places a stack of products on the feeding lifting plate 21, which is initially positioned by the limit rod 6. When the equipment is working, the feeding lifting mechanism 2 drives the feeding lifting plate 21 to rise until the positioning sensor 7 detects that the top layer of products has reached the gripping position. During this process, the sides of the products are physically combed by the anti-sticking brush 42, while the ion air bar 52 continuously blows out ion air to eliminate static electricity on the product surface.

[0033] Subsequently, the material handling robot 3 begins operation. The robot's lateral movement module 35 drives the material handling mounting frame 36 to move above the product. The material handling lifting cylinder 37 drives the first material handling suction cup 32 to descend and contact the product surface, while the shaking cylinder 31 also drives the second material handling suction cup 33 to descend and contact the product surface. The negative pressure device is activated, and the first and second material handling suction cups 32 and 33 simultaneously adhere to the topmost product. Next, the shaking cylinder 31 drives the second material handling suction cup 33 and the adhered product portion to perform rapid, small-amplitude up-and-down shaking to further ensure that only a single piece of product is picked up. Then, the material handling lifting cylinder 37 lifts up, and the robot's lateral movement module 35 moves the product above the product conveyor belt. The suction cups release the negative pressure, and the product is accurately placed onto the product conveyor belt, completing one loading cycle.

[0034] After loading is completed, the loading lifting mechanism 2 drives the unloading lifting plate 21 to rise another step, ready for the next grab. This cycle continues until the material shortage sensor 8 detects that the product is used up, and the system alarms to prompt for loading.

The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
