Description

Technical Field

[0001] This utility model relates to the field of heat dissipation substrate blank equipment, and in particular to a fully automatic coating equipment for heat dissipation substrate blanks. Background Technology

[0002] Coating the substrate blank is a key surface treatment process in substrate processing, effectively protecting the substrate surface from damage and contamination. Existing substrate coating equipment has been applied in this field. For example, a coating machine disclosed in Chinese invention patent publication number CN102991750A includes a coating platform, a film winding mechanism, a roller pressing head device, a marking head system, a positioning sensor, and an optical detector. It can perform coating operations on the substrate by peeling off the film on the film winding mechanism and rolling it onto the substrate, while using an optical detector to detect the quality of the substrate before and after coating.

[0003] However, existing coating equipment still has room for improvement in practical applications: to achieve precise positioning of the substrate during the coating process, it is necessary to design and manufacture corresponding support fixtures according to the size of the substrate, which undoubtedly increases the manufacturing cost of the equipment. Secondly, when using mechanical automation equipment to place the substrate into the support fixture, it needs to be placed one by one. During the coating process, the substrate is fed to the coating mechanism one by one by a turntable. In this process, the continuity of substrate feeding is not ideal, which means that the efficiency of substrate coating can be improved. Utility Model Content

[0006] In the aforementioned fully automatic coating equipment for heat dissipation substrate blanks, the pin positioning assembly includes a positioning cylinder disposed in an L-shaped coating table. The lifting end of the positioning cylinder is provided with a lifting plate, and the end of the lifting plate is provided with a positioning pin that extends into the coating station and fits with the through hole on the heat dissipation substrate blank.

[0007] In the aforementioned fully automatic coating equipment for heat dissipation substrate blanks, the top of the positioning pin has an elastic trigger pin, which is connected to the input terminal of the PLC control board via a circuit, and an alarm light is connected to the output terminal of the PLC control board.

[0008] In the aforementioned fully automatic coating equipment for heat dissipation substrate blanks, the film separating plate includes a fixed plate disposed on the plane of the main plate, the fixed plate is provided with a sharp blade plate, and the film strip contacts the edge of the sharp blade plate; the sharp blade plate is provided with a fixed strip and a movable strip for limiting the film strip.

[0009] In the aforementioned fully automatic coating equipment for heat dissipation substrate blanks, the roller assembly includes a cylinder fixing frame disposed at one end of the main plate, a film pressing cylinder disposed on the cylinder fixing frame, a roller frame connected to the extended end of the film pressing cylinder, and a pressure roller corresponding to the film separation plate disposed inside the roller frame.

[0010] In the aforementioned fully automatic coating equipment for heat dissipation substrate blanks, the cylinder fixing frame is provided with mutually symmetrical guide cylinders, and the guide cylinders are provided with guide rods connected to the roller frame.

[0011] In the aforementioned fully automatic coating equipment for heat dissipation substrate blanks, the feeding assembly includes a side plate disposed at one end of an L-shaped coating stage, a rodless cylinder disposed on the inner side of the side plate, a linkage rod disposed at the moving end of the rodless cylinder, and a push plate disposed at the end of the linkage rod within a guide groove of the L-shaped coating stage.

[0012] In the aforementioned fully automatic coating equipment for heat dissipation substrate blanks, the discharge assembly includes a sliding cylinder disposed on one side of the support portion of the L-shaped coating table. The extended end of the sliding cylinder is connected to a lifting cylinder, and the extended end of the lifting cylinder is provided with a lifting plate. The lifting plate is provided with multiple lifting columns for passing through the removal slot.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In this utility model, the film strip is wound around the film conveying mechanism, with one end of the film strip bypassing the film separation plate. The substrate blank is placed in the coating station by the pushing of the feeding component, and the pushing end of the feeding component stably abuts the substrate blank until the coating is completed. One corner of the substrate blank is attached to the right angle side in the coating station to complete the positioning of the substrate blank. Then, the film is covered on the substrate blank. After the coating is completed, the substrate blank is moved outward by the discharge component. The feeding component realizes the dual functions of feeding and positioning. The structure is simple, no additional positioning component is required, saving costs, and can maintain the stable positioning of the substrate blank. The feeding component and the discharge component realize continuous feeding and discharging of the substrate blank, which significantly improves the efficiency of substrate coating. In addition, after the heat dissipation substrate blank is positioned by the feeding component, the positioning end of the pin positioning component will pass through the round hole in the coating station and be inserted into the through hole of the heat dissipation substrate blank. If it can be inserted into the through hole smoothly, it means that the positioning is accurate. If it cannot be inserted, it means that the positioning of the heat dissipation substrate blank is inaccurate. The pin positioning component is used to assist in detecting the positioning accuracy of the heat dissipation substrate blank.

[0015] 2. In the pin positioning assembly, after the heat dissipation substrate blank is positioned by the feeding assembly, the positioning cylinder is activated to lift the lifting plate with the positioning pin. When the positioning pin can be smoothly inserted into the through hole of the heat dissipation substrate blank, the elastic trigger pin at the top of the positioning pin will not be displaced, and the alarm will not be triggered. When the elastic trigger pin at the top of the positioning pin is blocked from being inserted into the through hole of the heat dissipation substrate blank, the elastic trigger pin at the top of the positioning pin will come into contact with the plate body of the substrate blank, and the elastic trigger pin will be displaced under pressure, thereby triggering the signal. After receiving the signal, the PLC control board will transmit it to the alarm light, and the alarm light will flash to remind the operator that there is a problem with the positioning of the heat dissipation substrate blank.

[0016] 3. The membrane separation plate uses the sharpness of its blade to separate the membrane from the base tape, ensuring accurate membrane peeling position and neat edges. The adjustability of the movable strip allows it to adapt to membrane tapes of different widths, enhancing the equipment's compatibility with various specifications of membrane materials.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0025] Example: A fully automated coating equipment for heat dissipation substrate blanks, including a base plate 1, as shown in the attached figure. Figure 1 As shown, a main plate 2 is mounted on the base plate 1, and a film conveying mechanism 3 for conveying film material is mounted on the main plate 2. A film separating plate 4 is mounted on one side of the main plate 2, as shown in the attached figure. Figure 2As shown, the film strip is wound around the membrane separation plate 4; the film conveying mechanism mainly includes a material roll and a recovery roll set on the plane of the main body plate, as well as multiple dispersed drive rollers and a traction component. The film strip is usually placed in a roll on the material roll. The film strip is pulled out and wound around the multiple drive rollers, and then around the membrane separation plate, then through the traction component, and finally wound around the recovery roll. The recovery roll mainly winds up the empty film strip; the traction component and the recovery roll are uniformly driven by motors and are the power source for the entire film conveying mechanism. During operation, the entire film strip is in a taut state, and the film covering the substrate blank... The film is adhered to the film strip, and the film needs to be peeled off the film strip during lamination. The film separation plate 4 includes a fixed plate 14 set on the plane of the main plate 2. A sharp blade plate 15 is installed on the fixed plate 14, and the film strip contacts the edge of the sharp blade plate 15. The film can be peeled off one side of the film strip by touching the tip of the sharp blade plate. The sharp blade plate 15 is equipped with a fixed strip 16 and a movable strip 17 for limiting the film strip. The sharp blade plate has an adjustment groove, and the movable strip can move along the adjustment groove. The adjustability of the movable strip allows it to adapt to film strips of different widths, enhancing the equipment's compatibility with various specifications of film strips. A workbench 5 is mounted on the base plate 1. An advance translation assembly 6 is mounted on the workbench 5. A translation stage 7 is mounted on the moving end of the advance translation assembly 6. The advance translation assembly mainly consists of a motor and a conveyor belt. The bottom of the translation stage is fixed to one end of the conveyor belt. The translation stage can move laterally when the conveyor belt is running. An L-shaped laminating table 8 is mounted on the translation stage 7. An infeed assembly 9 and an outfeed assembly 10 are respectively mounted on the infeed and outfeed ends of the L-shaped laminating table 8. The L-shaped laminating table 8 has a laminating station 11, as shown in the attached figure. Figure 3 As shown, the L-shaped coating station 8 is provided with a pin positioning assembly 12. The positioning end of the pin positioning assembly 12 extends into the coating station 11 and fits with the through hole on the heat dissipation substrate blank. The main plate 2 is provided with a roller assembly 13 for pressing the film on the plate surface and at the end corresponding to the film separation plate 4. The roller assembly 13 includes a cylinder fixing frame 18 set at one end of the main plate 2. A pressing cylinder 19 is installed on the cylinder fixing frame 18. The extended end of the pressing cylinder 19 is connected to a roller frame 20. The roller frame 20 is provided with a pressing roller 21 corresponding to the film separation plate 4. After the substrate blank is positioned, the advance translation component moves the L-shaped coating stage 8 to the film separation plate. The film separation plate peels off one side of the film and attaches it to the substrate blank. At the same time, the pressing cylinder moves the pressure roller downward, and the pressure roller presses the film onto the substrate blank, smoothly covering it. At this time, the advance translation component moves back, and the film gradually covers the substrate blank, while the pressure roller rolls along with the film. The cylinder fixing frame 18 is equipped with symmetrical guide cylinders 22, and the guide cylinders 22 are equipped with guide rods 23 connected to the roller frame 20. This structure mainly serves to stabilize the pressure roller during its up and down movement.

[0026] The pin positioning assembly 12 includes a positioning cylinder 24 disposed within the L-shaped laminating table 8, as shown in the attached figure. Figure 4 As shown, a lifting plate 25 is installed on the lifting end of the positioning cylinder 24. The end of the lifting plate 25 is provided with a positioning pin 26 that extends into the coating station 11 and engages with the through holes on the heat dissipation substrate blank. The heat dissipation substrate blank itself has positioning holes at both ends. The heat dissipation substrate blanks come in various models, and the positions of the through holes on the blanks are also different. The coating station also has multiple hole positions. Therefore, the lifting plate and the lifting end of the positioning cylinder can be detached, and different models of lifting plates can be installed, allowing the positioning pin to adapt to the heat dissipation substrate blank to be coated. In specific applications, the positioning pin can be slightly smaller than the through holes of the heat dissipation substrate blank, so that the positioning pin can smoothly extend into the through holes when the heat dissipation substrate blank is accurately positioned. The top of the positioning pin 26 has an elastic trigger pin 36, as shown in the attached figure. Figure 6 As shown, the circuit connects to the input terminal of the PLC control board, and the output terminal of the PLC control board is connected to the alarm light 35 and the motor driving the film material transfer mechanism. When the elastic trigger pin 36 can smoothly engage in the through hole of the heat dissipation substrate blank, the elastic trigger pin 36 will not move, and the alarm will not be triggered. When the elastic trigger pin at the top of the positioning pin is obstructed from engaging in the through hole of the heat dissipation substrate blank, the elastic trigger pin at the top of the positioning pin comes into contact with the body of the substrate blank, and the elastic trigger pin is displaced under pressure, thus triggering the signal. After receiving the trigger level signal, the PLC control board sends a signal to the alarm light, and the alarm light flashes, reminding the operator that there is a problem with the positioning of the heat dissipation substrate blank and reminding the operator to reset the material. At the same time, the signal is transmitted to the motor driving the film material transfer mechanism, causing the motor to stop rotating. It should be noted that since the elastic trigger pin at the top of the positioning pin is conventional technology in this field and is a commercially available product, those skilled in the art can understand and implement this structure and its operating principle. Therefore, the specific structure and circuit will not be described in detail here.

[0027] The feeding assembly 9 includes a side plate 27 disposed at one end of the L-shaped coating table 8, as shown in the attached figure. Figure 5 As shown, a rodless cylinder 28 is installed on the inner side of the side plate 27. A linkage rod 29 is installed on the moving end of the rodless cylinder 28. A push plate 30 located in the guide groove of the L-shaped coating stage 8 is installed at the end of the linkage rod 29. The heat dissipation substrate blank is placed at the feed end of the L-shaped coating stage. The rodless cylinder drives the push plate to move through the linkage rod. The push plate will drive the heat dissipation substrate blank to move inward. The heat dissipation substrate blank enters the coating station. After the heat dissipation substrate blank is in the coating station, the push plate will always hold the heat dissipation substrate blank to achieve clamping and positioning of the heat dissipation substrate blank. The height of the upper end of the push plate is lower than or flush with the height of the heat dissipation substrate blank to ensure that the film separation plate does not interfere with the push plate during coating.

[0028] The discharge assembly 10 includes a sliding cylinder 31 disposed on one side of the support portion of the L-shaped coating stage 8. The extended end of the sliding cylinder 31 is connected to a lifting cylinder 32. The extended end of the lifting cylinder 32 is equipped with a lifting plate 33. Multiple lifting columns 34 for passing through the removal slot are mounted on the lifting plate. The sliding cylinder retracts, causing the lifting plate and lifting columns to move toward the heat dissipation substrate blank. After the lifting columns move below the heat dissipation substrate blank, the lifting cylinder operates, and the lifting plate and lifting columns rise, separating the heat dissipation substrate blank from the coating station. The sliding cylinder extends, thereby realizing the discharge of the heat dissipation substrate blank. The lifting plate has an I-shaped structure, and the lifting columns are disposed at the four ends of the lifting plate.

[0029] The working principle of this utility model is as follows: After the equipment is started, the film material transfer mechanism 3 first enters the working state; at the same time, the feeding component 9 begins to transport the heat dissipation substrate blank, and the rodless cylinder 28 drives the linkage rod 29 to move the push plate 30 along the guide groove of the L-shaped coating stage 8, pushing the substrate blank into the coating station 11 of the L-shaped coating stage 8. At this time, one corner of the substrate blank is in contact with the right angle side of the coating station 11, and the substrate is always clamped, so that one corner of it is in contact with the right angle side of the coating station 11, completing the initial positioning. The positioning cylinder 24 The lifting plate 25 is raised, causing the positioning pin 2 to extend into the laminating station 11. If the elastic trigger pin 36 at the top of the positioning pin 26 accurately engages with the through hole of the substrate blank, the positioning is qualified. If the engagement is obstructed, the positioning pin 26 sends a signal to the PLC, triggering the alarm light and pausing the film material transmission to ensure reliable positioning. After positioning, the advance translation component 6 drives the translation stage 7 and the L-shaped laminating stage 8 to move towards the film separation plate 4, bringing the substrate blank closer to the separated film. When the substrate blank moves to the designated position, the film is separated. One end of the film, which has separated from the substrate at point 4, is attached to the surface of the substrate blank. The roller assembly 13 starts simultaneously, and the pressing cylinder 19 pushes the roller frame 20 and the pressure roller 21 downwards. Guided by the guide cylinder 22 and the guide rod 23, the pressure roller 21 smoothly contacts the film, initially pressing it onto the substrate blank. Subsequently, the advance translation assembly 6 drives the heat dissipation substrate blank L-shaped coating stage back. During this process, the pressure roller 21 continues to roll and adhere to the film, gradually and completely covering the surface of the substrate blank, completing the coating operation. After completion, the feeding component 9 is reset, and the discharging component 10 starts working. The sliding cylinder 31 drives the lifting cylinder 32 and the lifting plate 33 to move towards the substrate blank, so that the lifting column 34 on the lifting plate 33 passes through the removal channel of the heat dissipation substrate blank L heat dissipation substrate blank type coating stage and is located below the substrate blank. Then, the lifting cylinder 32 pushes the lifting plate 33 to rise, and the lifting column 34 lifts the substrate blank from the coating station 11. Then, the sliding cylinder 31 retracts, driving the coated substrate blank to be removed from the equipment, completing the entire coating process.
