Description

Technical Field

[0001] This application relates to the field of chip processing and manufacturing, and in particular to a material preparation device for a film laminating machine. Background Technology

[0002] In the back-end packaging and testing stages of chip manufacturing, inspecting the finished chips in terms of appearance and performance is a crucial step in ensuring the quality of the final product. Typically, the chips to be inspected are placed on a metal tray covered with a plastic film to prevent electrostatic damage caused by direct contact with the metal surface.

[0003] In existing technologies, laminating equipment has a storage bin for stacking and storing metal pallets. Specifically, the storage bin includes a side panel and a lifting drive. The side panel is vertically mounted on a horizontal platform and is tubular. One side of the side panel has a notch that is vertically connected. The inside of the side panel is for storing metal pallets. The lifting drive is located inside the side panel but below it. The lifting drive lifts the stacked metal pallets upward so that the topmost metal pallet is at the same height. At this time, the adsorption device above the storage bin will pick up the metal pallet and transfer it to the next work station.

[0004] During the above process, when the metal trays in the material storage bin are depleted, the equipment must be stopped and the operator manually replenishes the filler. Only after this is completed can the equipment resume operation. Although this method allows the adsorption device to pick up metal trays at the same height, the filling of the metal trays still relies on manual intervention, and the machine must be stopped every time materials are replenished. If the metal trays are consumed quickly, the equipment needs to be started and stopped frequently, which seriously affects the overall production efficiency.

[0005] Therefore, in order to solve the problems in the prior art, this utility model proposes a material preparation device for a film applicator. Utility Model Content

[0006] The purpose of this utility model embodiment is to provide a material preparation device for a film applicator, so as to solve the problem in the prior art that the material preparation device of the film applicator requires frequent manual starting and stopping of the equipment to replenish the material.

[0007] To solve the above problems, the technical solution of this utility model embodiment is as follows:

[0008] This utility model embodiment provides a material preparation device for a laminating machine, including a frame; a material bin disposed on the frame, the material bin having a material receiving groove, the groove opening of the material receiving groove being located on the upper side of the material bin, one side wall of the material receiving groove being opened to form a material inlet window, and the opposite side wall being provided with a clearance window; a stop block movably disposed on the frame, the stop block being located at one vertical edge of the material inlet window, the side of the stop block near the material receiving groove being used to abut against the workpiece, the stop block being clearance-friendly to remove or form obstruction of the material inlet window; a lifting plate vertically slidably disposed on the frame, one end of the lifting plate being located in the material receiving groove and used to abut against the bottom surface of the workpiece, the other end passing through the clearance window and connected to a lifting drive member, the lifting plate having a clearance-friendly structure or the lifting drive member causing the lifting plate to perform clearance movement, for the purpose of moving the lifting plate away from the area where the material receiving groove is located.

[0009] Furthermore, in a preferred embodiment, the supplementary block is horizontally slidable, and the direction of movement of the supplementary block is perpendicular to the center line of the feed window.

[0010] Furthermore, in a preferred embodiment, the side of the auxiliary block away from the material trough is provided with a shifting guide surface, which is inclined and is used to abut against the workpiece outside the material trough, so that the workpiece exerts a force on the auxiliary block to move away from the feed window; a return spring is provided between the auxiliary block and the frame, which is used to exert a force on the auxiliary block to move into the feed window.

[0011] Furthermore, in a preferred embodiment, two supplementary blocks are provided, with the two supplementary blocks located at the two vertical edges of the feed window, respectively.

[0012] Further, in a preferred embodiment, the lifting plate includes an outer connecting portion and a supporting portion. The outer connecting portion is located outside the material receiving trough, and one end of the outer connecting portion is connected to the lifting drive member. One end of the supporting portion is located inside the material receiving trough, and the other end extends through the clearance window and is restrictedly hinged to the outer connecting portion. The restricted hinge prevents the supporting portion from rotating downward relative to the outer connecting portion when it abuts against the bottom surface of the workpiece, and allows the supporting portion to close upward relative to the outer connecting portion when it abuts against the top surface of the workpiece. The bottom of the material receiving trough is provided with an opening allowance groove, and the side wall opening of the opening allowance groove is provided to communicate with the clearance window. The opening allowance groove allows the supporting portion to open downward relative to the outer connecting portion.

[0013] Furthermore, in a preferred embodiment, the lifting plate extends from the end face away from the lifting drive member to the feed window, and a residual material limiting block is connected to the end face of the lifting plate away from the lifting drive member. The side of the residual material limiting block near the receiving groove is used to abut against the workpiece.

[0014] Further, in a preferred embodiment, the frame is provided with a feeding base, a feeding block, a pushing block, and a pushing drive. The upper surface of the feeding base is for stacking workpieces. Two feeding blocks are spaced apart, forming an infeed channel between them. The infeed channel communicates with the infeed window. The infeed channel is divided into an outlet area, a guide area, and a discharge area along the direction away from the infeed window. In the outlet area, the sides of the feeding blocks that are close to each other abut against the side of the workpiece. In the guide area, the spacing between the feeding blocks gradually decreases towards the outlet area. In the discharge area, the sides of the feeding blocks that are close to each other are spaced apart from the workpiece. The pushing block is slidably disposed in the infeed channel, with the sliding direction parallel to the extension direction of the infeed channel. The pushing block is used to abut against the side of the workpiece away from the infeed window. The pushing drive is connected to the pushing block.

[0015] Furthermore, in a preferred embodiment, in the material guiding area, a guide roller is rotatably embedded on one side of the material guiding blocks that are close to each other. The guide roller is used to abut against the side of the workpiece, and the rotation axis of the guide roller is vertically arranged.

[0016] Compared with the prior art, the material preparation device for a film applicator provided in this embodiment of the present invention has the following advantages:

[0017] 1. By using a lifting plate to lift the workpiece in the hopper, the material handling mechanism above the hopper can pick up the workpiece in a constant position. In addition, a sliding stop is set at one vertical edge of the feeding window to prevent the workpiece in the hopper from sliding out of the feeding window. At the same time, the sliding setting can also allow the workpiece to enter the hopper.

[0018] 2. By using a pusher block, the workpiece placed on the feeding base is pushed into the material storage trough of the hopper by the pusher drive, which reduces the process of manually replenishing the material into the hopper. At the same time, with the cooperation of the lifting plate and the pusher block, when the workpiece on the lifting plate is almost consumed, the pusher block can replenish the material into the material storage trough of the hopper, which improves the working efficiency of the equipment.

Detailed Implementation

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This utility model provides a material preparation device for a film applicator.

[0027] Reference Figure 1 The material preparation device includes a frame 1, a hopper 2, a replenishment block, and a lifting plate 4. Specifically, the frame 1 serves as the installation support foundation for the entire device and is typically installed on a horizontal platform. The hopper 2 is mounted on the frame 1 and has a material receiving trough 21. The opening of the material receiving trough 21 is located on the upper side of the hopper 2. Since the material picking mechanism of the laminating machine is located above the hopper 2, the opening of the material receiving trough 21 is positioned on the upper side of the hopper 2 to facilitate material picking by the picking mechanism from above the hopper 2. In addition, one side wall of the material receiving trough 21 has an opening to form an inlet window 22 for the workpiece to enter. The reason why the inlet window 22 is located on one side wall of the material receiving trough 21 is based on the working environment of the laminating machine. If the opening of the material receiving trough 21 also serves as a channel for storing workpieces into the hopper 2, it would easily cause interference and affect the efficiency of the equipment. The opposite side wall of the material receiving trough 21 has an avoidance window 23.

[0028] The auxiliary block 3 is movably mounted on the frame 1. The auxiliary block 3 is located at the vertical edge of one side of the feed window 22. The side of the auxiliary block 3 near the material trough 21 abuts against the workpiece. The auxiliary block 3 can be set to avoid obstruction, so as to remove or form obstruction of the feed window 22. Specifically, the workpiece needs to be fixed in the hopper 2. The feed window 22 is set on one side wall of the hopper 2. During use, the workpiece may slide out at the position of the feed window 22. Therefore, it is necessary to set the auxiliary block 3 at the vertical edge of one side of the feed window 22 to limit the workpiece.

[0029] The lifting plate 4 is vertically slidably mounted on the frame 1. One end of the lifting plate 4 is located inside the material receiving trough 21, abutting against the bottom surface of the workpiece. The other end passes through the clearance window 23 and is connected to the lifting drive 7. The lifting plate 4 has a clearance-allowing structure, or the lifting drive 7 causes the lifting plate 4 to perform a clearance movement, so that the lifting plate 4 leaves the area where the material receiving trough 21 is located. Specifically, without changing the movement of the material handling mechanism, the lifting plate 4 is used to move the workpiece upward, which can also ensure that the material handling mechanism picks up materials at a constant position. When the workpiece on the lifting plate 4 is almost used up, the hopper 2 below the lifting plate 4 can be filled with new workpieces. When the workpiece on the lifting plate 4 is used up, the lifting plate 4 will be blocked by the newly filled workpieces when it descends to the bottom of the hopper 2. Therefore, in order for the lifting plate 4 to descend to the bottom of the hopper 2, the lifting plate 4 must have a clearance-allowing structure, or the lifting drive 7 must be used to cause the lifting plate 4 to perform a clearance movement.

[0030] In summary, by raising the lifting plate 4 to gradually raise the workpiece in the hopper 2, the material handling mechanism can pick up the workpiece at a constant position. Furthermore, by setting a stop block on one vertical edge of the infeed window 22, the workpiece will not slide out along the infeed window 22.

[0031] As mentioned above, a stop block 3 is set at one vertical edge of the feed window 22. The stop block 3 is designed to be avoidable. The core of the avoidable design is that the stop block can move and can leave the feed window 22 to release the restriction on the workpiece, and can enter the feed window 22 to form a restriction on the workpiece. In order to simplify the setting structure of the stop block 3, the stop block 3 adopts a horizontal sliding setting method, and its movement direction is perpendicular to the center line of the feed window 22.

[0032] refer to Figure 1-2Furthermore, based on the aforementioned horizontal sliding setting of the auxiliary block 3, an inclined shifting guide surface 31 is formed on the side of the auxiliary block 3 away from the feed window 22. The shifting guide surface 31 makes the end of the auxiliary block 3 closer to the center of the feed window 22 thinner. When the workpiece outside the receiving trough 21 moves towards the feed window 22, it will abut against the shifting guide surface 31, thereby applying a force to the auxiliary block 3 to make it move away from the feed window 22, realizing the automatic avoidance of the auxiliary block 3. At the same time, a return spring 5 is provided between the auxiliary block 3 and the frame 1. After the workpiece has completely entered the receiving trough 21, the return spring 5 will apply a force to the auxiliary block 3 to move into the feed window 22, so that the auxiliary block 3 resets and abuts against the workpiece again, completing the limit.

[0033] The aforementioned resetting spring 5 is used to make the auxiliary block 3 slide horizontally relative to the feed window 22, so that the auxiliary block 3 can both restrict the workpiece in the hopper 2 and help the workpiece enter through the feed window 22. In other embodiments, in order to achieve this function of the resetting spring 5, a magnetic repulsion and air pressure can also be used to apply a restoring force to the auxiliary block 3.

[0034] In other embodiments, the auxiliary block 3 may not need to be provided with a shift guide surface 31, but may be directly connected to a drive source to achieve the purpose of releasing or limiting the workpiece by the auxiliary block 3.

[0035] refer to Figure 1-2 Furthermore, in order to enhance the limiting effect of the auxiliary block 3 on the workpiece, two auxiliary blocks 3 are provided, located at the two vertical edges of the feed window 22 respectively. Through the combined action of both sides, the position of the workpiece in the material trough 21 can be more stably restricted, preventing the workpiece from deviating.

[0036] As mentioned above, in order for the lifting plate 4 to descend to the bottom of the hopper 2, the lifting plate 4 should have a clearance structure or use a lifting drive 7 to make the lifting plate 4 make clearance movements. If the lifting drive 7 makes the lifting plate 4 make clearance movements, the working principle can be as follows: the lifting drive 7 first makes the lifting plate 4 rise to gradually lift the workpiece upwards. After the previous batch of workpieces is transferred away by the material handling mechanism, the lifting drive 7 then makes the lifting plate 4 move horizontally to leave the area where the material trough 21 is located. The lifting drive 7 then makes the lifting plate 4 move horizontally to enter the area where the material trough 21 is located and be located below the next batch of workpieces, so as to achieve the lifting of the next batch of workpieces.

[0037] refer to Figure 1 and Figure 3-4In this embodiment, considering structural simplicity and equipment installation space, the lifting plate 4 is preferably designed with a clearance mechanism. Specifically, the lifting plate 4 includes an outer connecting part 41 and a supporting part 42. The outer connecting part 41 is located outside the material receiving trough 21 and one end is connected to the lifting drive member 7. One end of the supporting part 42 is located inside the material receiving trough 21, and the other end extends out through the clearance window 23 and forms a restrictive hinge with the outer connecting part 41. This hinge mechanism prevents the supporting part 42 from rotating downward relative to the outer connecting part 41 when it abuts against the bottom surface of the workpiece, ensuring stable bearing. When the supporting part 42 abuts against the top surface of the workpiece, it can close upward relative to the outer connecting part 41 to achieve clearance. This can be achieved using a hinge 8. Meanwhile, the bottom of the material receiving trough 21 is provided with an opening allowance groove 211, the opening of which communicates with the clearance window 23, providing space for the supporting part 42 to open downward relative to the outer connecting part 41, ensuring that the movement of the lifting plate 4 is unimpeded.

[0038] In other embodiments, if the rotation at the hinge is not smooth, a torsion spring can be added between the outer connecting part 41 and the supporting part 42 so that the supporting part 42 can be quickly opened in the opening allowance groove 211.

[0039] Furthermore, in order to have more time to replenish the next batch of workpieces into the hopper 2, it is preferable to carry out the replenishment work when there is still a part of the previous batch of workpieces remaining. However, since the replenishment block 3 will leave the feeding window 22 during the replenishment work, in order to stabilize the remaining workpieces, the end face of the lifting plate 4 away from the lifting drive 7 extends to the feeding window 22, and a residual material limiting block 43 is connected at this end face. The side of the residual material limiting block 43 near the material trough 21 abuts against the workpiece to prevent the remaining workpieces from sliding off the side of the feeding window 22.

[0040] In summary, by adopting the lift plate 4 with an obstacle-avoiding structure, the working principle is as follows: when the lift plate 4 descends, the supporting part 42 will flip upward and close relative to the external connecting part 41 due to the obstruction of the workpiece. When the supporting part 42 reaches the opening allowance groove 211, the supporting part 42 will flip downward and open relative to the external connecting part 41 to lift the next batch of workpieces. Thus, the lift plate 4 can be lowered to the bottom of the hopper 2 without moving the lift plate 4. This design simplifies the structure and is highly efficient.

[0041] As mentioned above, a feeding window 22 is provided on the side wall opening of the material trough 21 of the material bin 2. The feeding window 22 is for the workpiece to enter. In this process, the workpiece can be put into the material bin 2 manually through the feeding window 22, or a replenishing mechanism can be added to push the workpiece in through the feeding window 22. In order to make the film applicator work more efficiently, automatic replenishment is more appropriate.

[0042] Reference Figure 1-2Specifically, the frame 1 is also equipped with a feeding base 11, feeding blocks 12, pushing blocks 13, and a pushing drive 14. The upper surface of the feeding base 11 is for stacking workpieces; two feeding blocks 12 are spaced apart, forming a feeding channel 6 that communicates with the feeding window 22. The feeding channel 6 is divided into a discharge area 61, a guiding area 62, and a release area 63 along the direction away from the feeding window 22. Among them, the spacing of the feeding blocks 12 in the discharge area 61 matches the workpiece and can abut against the side of the workpiece; the spacing of the feeding blocks 12 in the guiding area 62 gradually decreases towards the discharge area 61, playing a guiding role. Here, the guidance is carried out along the direction perpendicular to the length of the feeding channel 6; the spacing of the feeding blocks 12 in the release area 63 is greater than the width of the workpiece, which facilitates the placement of the workpiece. The pusher block 13 is slidably disposed in the feed channel 6, with the sliding direction parallel to the extension direction of the feed channel 6. It is used to abut the side of the workpiece away from the feed window 22. The pusher drive 14 is connected to the pusher block 13 and drives it to push the workpiece into the receiving trough 21.

[0043] In selecting the pusher drive 14, to achieve the pushing effect, a cylinder, hydraulic cylinder, etc., can be chosen. Cylinders are mostly used in situations requiring high speed and low load, while hydraulic cylinders are usually used in situations requiring high load, meaning that hydraulic cylinders have a stronger pushing force than cylinders. Considering the operating environment of this device, the workpiece to be pushed is a thin metal sheet. Stacking many thin metal sheets together in the feeding area 63 and pushing these thin metal sheets with the pusher drive 14 is a high-load operation. Therefore, in this embodiment, selecting a hydraulic cylinder as the pusher drive 14 is more suitable.

[0044] In summary, when operating this material preparation device, the worker only needs to place the stacked workpieces in the feeding area 63, and then push the workpieces to move under the action of the pushing drive component 14. After passing through the guiding area 62, the workpieces are aligned to the discharge area 61, and then the workpieces are pushed into the material receiving trough 21 of the hopper 2, thus completing the material replenishment of the device.

[0045] Reference Figure 1-2 Furthermore, in the material guiding area 62, a guide roller 621 is rotatably embedded on the side of the material guiding blocks 12 that are close to each other. The rotation axis of the guide roller 621 is vertically set. When the workpiece moves in the material guiding area 62, the guide roller 621 abuts against the side of the workpiece and rolls, which can reduce the frictional resistance when the workpiece moves and make the feeding process smoother.

[0046] In summary, the material preparation device of this laminating machine, through the coordinated operation of the frame 1, material bin 2, replenishment block 3, lifting plate 4, and automatic material replenishment, achieves material replenishment, stable storage, and precise lifting of the workpiece, which can effectively reduce the time of manual material preparation and significantly improve the working efficiency of the laminating machine in the material preparation process.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
