Description

Technical Field

[0001] This utility model relates to the field of adhesive applicator tools, and in particular to a blade replacement mechanism for an adhesive applicator. Background Technology

[0002] As panels become increasingly thinner and lighter, the thickness of their core components—chips—also needs to be reduced. Chips are made by cutting a single wafer into individual pieces using a fully automated dicing machine. Wafers are typically 6 / 8 / 12-inch round with a thickness of around 700-800µm, requiring a fully automated grinding machine to grind them to the required thickness. The front side of the wafer contains the integrated circuits, while the back side is the silicon dioxide layer that needs to be ground off. During grinding, the wafer is placed face down on a worktable, with the grinding wheel on top. To prevent the worktable from scratching the integrated circuits, a protective film is applied to the front side of the wafer before grinding. After the film is applied, a cutting assembly removes any excess material.

[0003] Currently, the blades in the cutting assembly are directly tightened and fixed by the blade holder and bolts. Since the blades are in close contact with the wafer and are subjected to force, they will generally have gaps after about 200 uses. During processing, the blade holder mechanism is heated at high temperature, and there is a risk of burns and scratches when personnel change the blades. In addition, the machine downtime required for blade replacement is long, which will result in wasted production capacity and poor flexibility. In order to solve the above problems, we propose a blade replacement mechanism for adhesive application machines. Utility Model Content

[0004] The purpose of this invention is to provide a blade replacement mechanism for an adhesive applicator, which solves the problem that existing blade holder mechanisms are inconvenient for quick blade replacement and require a long time.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a blade replacement mechanism for an adhesive applicator, comprising a blade box, an inner frame welded inside the blade box, a threaded rod rotatably connected inside the blade box, a driving mechanism and a fixing mechanism respectively provided inside and at the bottom of the blade box, a push plate threadedly connected to the surface of the threaded rod, the other end of the push plate extending into the interior of the inner frame, a through slot opened at the top of the inner frame, a blade outlet opened at the bottom of the blade box, a PLC controller mounted on the front of the blade box, a box plate hinged to the front of the blade box, and a handle welded to the front of the box plate.

[0006] The above technical solution facilitates quick and easy blade replacement, achieving a completely contactless process that ensures personnel safety, reduces machine downtime and production waste, and is highly practical.

[0007] The present invention is further configured such that: the driving mechanism includes a reducer, the reducer is bolted to the inside of the tool box by a bracket, a motor is bolted to the bottom of the reducer, a first bevel gear is fixedly sleeved at the output end of the reducer, and a second bevel gear that cooperates with the first bevel gear is fixedly sleeved on the surface of the threaded rod.

[0008] By adopting the above technical solution, through the setting of the reducer, motor, first bevel gear and second bevel gear, the threaded rod can be driven and rotated slowly, so that the speed at which the push plate pushes the blade to move is less than the speed at which the blade falls from the exit point.

[0009] The present invention is further configured such that: the fixing mechanism includes a fixing frame, the fixing frame is welded to the bottom of the knife box, a cylinder is bolted through one side of the fixing frame, and a positioning plate is installed at the output end of the cylinder.

[0010] By adopting the above technical solution, the blade can be pressed and fixed by the setting of the fixing frame, cylinder and positioning plate to prevent the blade from falling off during the cutting process.

[0011] The present invention is further configured such that: an infrared transmitter is embedded in one side of the push plate, an infrared receiver is embedded in one side of the inner frame, and an audible and visual alarm is bolted to one side of the knife box.

[0012] By adopting the above technical solution, through the setting of infrared transmitter, infrared receiver and audible and visual alarm, the remaining status of blades inside the blade box can be detected in real time. If the infrared receiver does not receive the light emitted by the infrared transmitter, it means that there are blades left inside. Conversely, if the infrared receiver receives the light emitted by the infrared transmitter, it means that the blades inside are used up. The signal will be transmitted to the PLC controller to activate the audible and visual alarm to prompt personnel to add more.

[0013] The present invention is further configured such that: a limiting frame is bolted to the other side of the knife box, a movable block is provided inside the limiting frame, a limiting spring is bolted between the top of the movable block and the limiting frame through a spring fixing piece, a fixing rod is welded to the bottom of the movable block, and a baffle is rotatably connected to the other end of the fixing rod through a bearing.

[0014] By adopting the above technical solution, the blade can be temporarily supported when it falls from the exit point through the setting of the limiting frame, the moving block, the limiting spring, the fixing rod and the baffle.

[0015] The present invention is further configured such that: a pull rod is welded to the front of the movable block, and a sliding groove that cooperates with the pull rod is welded to the front of the limiting frame.

[0016] By adopting the above technical solution, the design of the pull rod and sliding groove makes it easy for personnel to pull the moving block downwards.

[0017] The present invention is further configured such that: a slide rail is bolted inside the knife box, and a slider that cooperates with the slide rail is welded to the top of the push plate.

[0018] By adopting the above technical solution, the slide rail and slider can be used to limit the push plate and prevent it from flipping over during left and right movement.

[0019] The present invention is further configured such that: a heat dissipation groove is provided on the top of the knife box, and a dustproof mesh is installed inside the heat dissipation groove.

[0020] By adopting the above technical solution, the ventilation effect inside the knife box can be improved by setting up heat dissipation slots and dustproof nets, and dust can be prevented from entering.

[0021] In summary, this utility model has the following beneficial effects:

[0022] This invention allows for quick and easy blade replacement by first opening the box panel to add blades to the inside of the blade box. After adding the blades, one hand grasps the pull rod to pull the baffle downwards. Once the pull rod is fully pulled down, the baffle is rotated to position itself below the fixed frame. Simultaneously, the reducer and motor are started to rotate the threaded rod. As the threaded rod rotates, it causes the push plate to move to the left. As the push plate moves to the left, it pushes the foremost blade down from the blade outlet. After the blade falls, the cylinder is activated to clamp the positioning plate. When a blade is damaged, the waste blade box is placed under the blade, and the cylinder is then activated to retract the positioning plate, allowing the blade to fall naturally. This facilitates quick blade replacement, and the entire replacement process is contactless, ensuring personnel safety and reducing machine downtime and wasted production capacity. It is highly practical. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] refer to Figure 1 , Figure 2 and Figure 3 A blade replacement mechanism for an adhesive applicator includes a blade box 1, an inner frame 2 welded inside the blade box 1, a threaded rod 3 rotatably connected inside the blade box 1, a drive mechanism 4 and a fixing mechanism 5 respectively provided inside and at the bottom of the blade box 1, a push plate 6 threadedly connected to the surface of the threaded rod 3, the other end of the push plate 6 extending into the interior of the inner frame 2, a through slot opened at the top of the inner frame 2, a blade outlet 7 opened at the bottom of the blade box 1, a PLC controller 8 mounted on the front of the blade box 1, a box plate 9 hinged to the front of the blade box 1, and a handle welded to the front of the box plate 9. Blades are replenished into the blade box 1 by first opening the box plate 9, and after replenishment, a pull rod 18 is grasped with one hand to pull down a baffle 17. When the lever 18 is pulled down to the bottom, the baffle 17 is rotated to be located below the fixed frame 51. Then, the reducer 41 and the motor 42 are started at the same time to drive the threaded rod 3 to rotate. When the threaded rod 3 rotates, it will drive the push plate 6 to move to the left. When the push plate 6 moves to the left, it will push the foremost blade to fall from the blade outlet 7. After the blade falls, the cylinder 52 is started to drive the positioning plate 53 to clamp it. When the blade is damaged, the waste blade box is placed under the blade. Then the cylinder 52 is started to drive the positioning plate 53 to retract, allowing the blade to fall naturally. This makes it easy to quickly replace the blade. The replacement process is completely contactless, which ensures the safety of personnel and reduces the machine downtime and the resulting waste of production capacity. It is highly practical.

[0029] refer to Figure 2The drive mechanism 4 includes a reducer 41, which is bolted to the inside of the blade box 1 via a bracket. A motor 42 is bolted to the bottom of the reducer 41. A first bevel gear 43 is fixedly sleeved at the output end of the reducer 41. A second bevel gear 44, which works in conjunction with the first bevel gear 43, is fixedly sleeved on the surface of the threaded rod 3. Through the arrangement of the reducer 41, the motor 42, the first bevel gear 43, and the second bevel gear 44, the threaded rod 3 can be driven and rotated slowly, so that the speed at which the push plate 6 pushes the blade is less than the speed at which the blade falls from the exit 7.

[0030] refer to Figure 2 The fixing mechanism 5 includes a fixing frame 51, which is welded to the bottom of the knife box 1. A cylinder 52 is bolted through one side of the fixing frame 51. A positioning plate 53 is installed at the output end of the cylinder 52. By setting the fixing frame 51, the cylinder 52 and the positioning plate 53, the blade can be pressed and fixed to prevent the blade from falling off during the cutting process.

[0031] refer to Figure 2 An infrared transmitter 10 is embedded on one side of the push plate 6, an infrared receiver 11 is embedded on one side of the inner frame 2, and an audible and visual alarm 12 is attached to one side of the knife box 1. Through the setting of the infrared transmitter 10, the infrared receiver 11, and the audible and visual alarm 12, the remaining status of the blades inside the knife box 1 can be detected in real time. If the infrared receiver 11 does not receive the light emitted by the infrared transmitter 10, it means that there are blades remaining inside. Conversely, if the infrared receiver 11 receives the light emitted by the infrared transmitter 10, it means that the blades inside are used up. The signal will be transmitted to the PLC controller 8 to activate the audible and visual alarm 12 to prompt personnel to add more.

[0032] refer to Figure 1 and Figure 2 On the other side of the blade box 1, a limiting frame 13 is bolted. Inside the limiting frame 13, a moving block 14 is provided. A limiting spring 15 is bolted between the top of the moving block 14 and the limiting frame 13 through a spring fixing plate. A fixing rod 16 is welded to the bottom of the moving block 14. The other end of the fixing rod 16 is rotatably connected to a baffle 17 through a bearing. Through the setting of the limiting frame 13, the moving block 14, the limiting spring 15, the fixing rod 16 and the baffle 17, temporary support can be provided when the blade falls from the blade outlet 7.

[0033] refer to Figure 1 and Figure 2 A pull rod 18 is welded to the front of the movable block 14, and a sliding groove 19 that works with the pull rod 18 is welded to the front of the limiting frame 13. The pull rod 18 and the sliding groove 19 make it easy for personnel to pull the movable block 14 downward.

[0034] refer to Figure 2 and Figure 3The inside of the knife box 1 is bolted with a slide rail 20, and the top of the push plate 6 is welded with a slider 21 that works with the slide rail 20. The slide rail 20 and the slider 21 can limit the push plate 6 and prevent it from flipping over during left and right movement.

[0035] refer to Figure 1 The top of the knife box 1 is provided with a heat dissipation groove 22, and a dustproof mesh is installed inside the heat dissipation groove 22. The heat dissipation groove 22 and the dustproof mesh can improve the ventilation effect inside the knife box 1 and prevent dust from entering.

[0036] Brief description of the usage process: First, open the box plate 9 to replenish the blade inside the blade box 1. After replenishing the blade, use one hand to grasp the pull rod 18 and pull the baffle 17 downward. After the pull rod 18 is pulled down to the bottom, rotate the baffle 17 so that it is located below the fixed frame 51. Then, at the same time, start the reducer 41 and the motor 42 to drive the threaded rod 3 to rotate. When the threaded rod 3 rotates, it will drive the push plate 6 to move to the left. When the push plate 6 moves to the left, it will push the foremost blade to fall from the blade outlet 7. After the blade falls, start the cylinder 52 to drive the positioning plate 53 to clamp it. When the blade is damaged, place the waste blade box under the blade. Then start the cylinder 52 to drive the positioning plate 53 to retract and let the blade fall naturally.
