Description

Technical Field

[0001] This utility model relates to the technical field of double-sided adhesive roll-on equipment, specifically to a double-sided adhesive roll-on module for PCB processing. Background Technology

[0002] Double-sided tape is widely used in the production and processing of PCBs (printed circuit boards) to fix components, including batteries and sensor modules, onto the PCB, thus avoiding the use of screws or clips. When double-sided tape is used to fix metal shielding covers on the PCB, it can effectively prevent electromagnetic interference from affecting the circuit. Using double-sided tape between the PCB and the metal casing can effectively provide insulation and shock protection, thereby effectively preventing friction or short circuits with the casing.

[0003] However, in current PCB manufacturing processes, due to the small size of PCBs and the limited amount of double-sided adhesive used, manual bonding is commonly employed. This manual bonding method is problematic because workers cannot quickly and comprehensively cover and press the adhesive surface between the double-sided adhesive and the workpiece, resulting in poor adhesion. Consequently, the adhesive surface easily separates and detaches during later use, causing the bonded object to fall off and affecting the proper operation of electronic devices. Therefore, it is necessary to improve and optimize the structure of the double-sided adhesive roll-on module to address these issues in current PCB manufacturing processes. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a double-sided adhesive roll-on module for PCB processing, which is characterized by facilitating the roll-on and pressing of double-sided adhesive.

[0024] Example

[0025] like Figure 1-4 As shown, the PCB processing double-sided adhesive roll-on module disclosed in this utility model includes an X-axis lead screw module 1, a Z-axis lead screw module 2 disposed on the X-axis lead screw module 1 and capable of horizontal displacement and sliding along the setting direction of the X-axis lead screw module 1, and a mounting seat 5 disposed on the Z-axis lead screw module 2 and capable of vertical displacement along the setting direction of the Z-axis lead screw module 2. The mounting seat 5 used in this technical solution is an L-shaped structure, and the structural strength is improved by splicing two L-shaped structures arranged in parallel. The mounting seat 5 is located away from the side wall of one end of the Z-axis lead screw module 2. A vertically arranged Z-axis slide rail 6 is fixedly provided. In this technical solution, two sets of Z-axis slide rails 6 are provided and arranged in parallel. A first telescopic cylinder 7 is also fixedly provided on the mounting base 5 above the Z-axis slide rail 6. The first telescopic cylinder 7 is electrically connected to the outside. A rolling roller 8 for rolling and pressing double-sided adhesive is connected to the output shaft of the first telescopic cylinder 7 through a U-shaped bracket. One side of the U-shaped bracket is fitted into the Z-axis slide rail 6 and can move along the laying direction of the Z-axis slide rail 6, synchronously driving the rolling roller 8 to move.

[0026] A rotating platform 11 is fixedly installed at the bottom of the mounting base 5. A driven platform 12 is fixedly connected to the bottom surface of the rotating part at the bottom of the rotating platform 11. A vacuum suction plate 17 is installed on the lower surface of the driven platform 12. The bottom surface of the vacuum suction plate 17 is provided with several vacuum suction holes. One end of the vacuum suction plate 17 is connected to an external negative pressure device through a pipe. The vacuum suction device maintains a negative pressure on the bottom surface of the vacuum suction plate 17. When the vacuum suction plate 17 is running, it is used to adsorb the workpiece that is attached to its bottom surface. A height adjustment telescopic cylinder 10 is fixedly installed on the upper surface of the driven platform 12 through a support frame. The output shaft of the height adjustment telescopic cylinder 10 passes through the driven platform 12 and is connected to the vacuum suction plate 17. When the height adjustment telescopic cylinder 10 is running, it adjusts the extension and retraction of the output shaft to change the height of the vacuum suction plate 17.

[0027] Specifically, a second servo motor 9 is fixedly installed on the inner side of the mounting base 5. The output shaft of the second servo motor 9 is connected to the rotating part of the rotating platform 11 through gear meshing. When the second servo motor 9 is running, it drives the output shaft to drive the gear inside the rotating part to rotate. In this embodiment, the rotating platform 11 is a bearing structure, and the rotating part is nested in the rotating platform 11 and can rotate horizontally on the bottom surface of the rotating platform.

[0028] Specifically, a first servo motor 3 is also provided at the top of the Z-axis lead screw module 2. The output shaft of the first servo motor 3 drives the lead screw inside the Z-axis lead screw module 2 to rotate, thereby causing the height of the mounting seat 5 sleeved on the lead screw to change. In this embodiment, the height of the entire rolling module changes synchronously by adjusting the height of the mounting seat 5.

[0029] Specifically, there can be two rollers 8, which are arranged in parallel and can simultaneously roll and press the double-sided adhesive on both sides of the PCB board.

[0030] Specifically, a second telescopic cylinder 13 is connected to both sides of the driven platform 12, and a driven arm 14 is connected to the output shaft of the second telescopic cylinder 13. A pressure plate 15 is connected to the other end of the two driven arms 14. The bottom surface of the pressure plate 15 is also uniformly provided with negative pressure vacuum suction holes. In this embodiment, the workpiece being processed can also be adsorbed through the pressure plate 15.

[0031] Specifically, the driven platform 12 is also provided with guide strips 16 arranged and fixedly installed on both sides of the driven arm 14. The vacuum suction plate 17 has a groove on its side that fits into the guide strips 16. When the driven arm 14 is pushed to move by the second telescopic cylinder 13, the tilt angle is adjusted by the vacuum suction plate 17. In this embodiment, the guide strips 16 are connected to the driven platform 12 by bolts. The tilt angle of the guide strips 16 can be adjusted by the staff according to the needs of the site.

[0032] Specifically, the vacuum suction plate 17 is connected to the vacuum negative pressure device through an air supply pipe. Several pressure gauges 4 are also mounted on the Z-axis lead screw module 2 via a bracket to display the air pressure of each cylinder and the air pressure data at the vacuum suction plate 17. In this embodiment, the operator can determine the operating status of each device by looking at the data displayed on the pressure gauges 4.

[0033] The working principle and usage process of this utility model: In the process of using this technical solution, the Z-axis lead screw module 2 can slide horizontally on the X-axis lead screw module 1 along the laying direction of the X-axis lead screw module 1, thereby adjusting the position of the Z-axis lead screw module 2 in the horizontal direction. By adjusting the operation of the first servo motor 3, the height of the mounting base 5 on the Z-axis lead screw module 2 is changed, thereby adjusting the height of the entire rolling module. During the height adjustment of the rolling module, the height of the vacuum suction plate 17 changes synchronously.

[0034] When the equipment is running, the PCB board to be processed will be transported to the bottom of the vacuum suction plate 17 by the externally laid conveyor. The upper and / or lower surfaces of the PCB board are covered with double-sided tape, which needs to be rolled and pressed by the roller module. When the device is running, the mounting base 5 sinks synchronously, which will make the bottom surface of the vacuum suction plate 17 contact the workpiece to be processed. The negative pressure vacuum pump connected to the vacuum suction plate 17 can make the bottom surface of the vacuum suction plate 17 be in a negative pressure state, so that the workpiece to be processed is tightly adsorbed on the bottom surface of the vacuum suction plate 17.

[0035] During operation, the height of the Z-axis slide rail 6 is adjusted synchronously by the first telescopic cylinder 7. The first telescopic cylinder 7 can push down the height of the Z-axis slide rail 6 so that the two sets of rollers can be on both sides of the workpiece being processed. If only one side of the PCB board needs to be processed, the extension range of the first telescopic cylinder 7 only needs to be adjusted so that the single rolling roller 8 contacts the bottom surface of the PCB board. During the rolling process, the rolling roller 8 rolls and presses the PCB board being transported and displaced, so that the double-sided adhesive is stably laid and fixed on the surface of the PCB board.

[0036] During operation, the second telescopic cylinder 13 pushes its telescopic rod out, thereby causing the driven arm 14 to move synchronously. During the movement of the driven arm 14, it moves downward through the guide guide 16 and adjusts its angle. At this time, it will synchronously drive the pressure plate 15 at the end of the driven arm 14 to rise together. During operation, the bottom surface of the pressure plate 15 can be kept at the same height as the bottom surface of the vacuum suction plate 17. At this time, the PCB board on the bottom surface of the vacuum suction plate 17 can be simultaneously subjected to negative pressure suction. When the two rollers in the rolling roller 8 roll and press the two surfaces of the PCB board, the pressure plate 15 applies negative pressure suction to one end of the PCB board, further improving the stability of the PCB board during rolling and pressing.

[0037] In this technical solution, a second servo motor 9 is also provided. During the operation of the second servo motor 9, its own output shaft is driven to rotate, which in turn drives the rotating part at the bottom of the rotating platform 11 to rotate. During the rotation of the rotating part, the driven platform 12 is driven to rotate at the same angular velocity, thereby synchronously adjusting the tilt angle of the vacuum suction plate 17 on the horizontal plane, so that the vacuum suction plate 17 can be more easily positioned with the PCB board when adsorbing the PCB board.

[0038] In this technical solution, a height-adjustable telescopic cylinder 10 is also provided in the mounting base 5. During operation, the height-adjustable telescopic cylinder 10 adjusts the height of the vacuum suction plate 17 by pushing its own telescopic rod to extend or shorten, so that the vacuum suction plate 17 can be closely attached to the workpiece being processed, thereby facilitating the double-sided adhesive roll-pressing process of the PCB board through the roll-appliance module.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to further limit the present utility model. All equivalent changes made based on the description and drawings of the present utility model are within the protection scope of the present utility model.
