Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing technology, and in particular to a double-sided chip mounter system. Background Technology

[0002] By embedding circuit designs into flexible, thin plastic sheets, flexible circuit boards are obtained, which are characterized by high wiring density, light weight, thinness, and good bending performance.

[0003] In existing technologies, processing equipment is installed along the side of the conveyor to perform operations such as patching and testing on flexible circuit boards to complete the patching process. Typically, only one side of the material strip can be patched during the operation of the production line. If the other side needs to be processed, the material strip needs to be flipped and then fed back into the production line for processing again. Repeated unwinding and rewinding can easily damage the material strip. The processing production line is relatively long, and repeated unwinding and rewinding can easily cause friction damage to the material strip. Moreover, it is difficult to ensure that the material strip is always in a flat state during processing, which can easily cause downtime, jamming, and low processing efficiency.

[0004] To address the aforementioned issues, Chinese Patent Application No. CN202410537271.4, entitled "A Double-Sided Patch Assembly Equipment," discloses a system that includes two sets of execution sections between a loading tray and a receiving tray. The material strip is processed by side-mounted processing equipment as it passes through these execution sections. A material strip conveying power mechanism and a material strip auxiliary power mechanism, located at the corner where the execution sections and the material trays change direction, together form the material strip power system. The material strip auxiliary power mechanism includes an adjusting roller and a leveling power assembly. By moving the adjusting roller, an interaction force is maintained between the material strip and the adjusting roller, ensuring the material strip remains flat and does not bend.

[0005] However, refer to the appendix Figure 2 In the existing technology, although setting a material conveyor power mechanism at the corner of the execution section can drive the material belt and change direction, it widens the material belt and increases its volume, requiring a larger installation space for installation and operation. This limits the applicable space range and is not conducive to the promotion and use of the equipment.

[0006] To address the problems in the existing technology, this utility model provides a double-sided chip mounter system. Utility Model Content

[0065] The present invention will be further described in detail below with reference to specific embodiments:

[0066] like Figure 1 As shown, a double-sided chip mounter system includes a roll unit 1, a chip mounting feeding mechanism 2, a leveling and conveying mechanism 3, and a stretching unit 4.

[0067] The material roll unit 1 includes a feeding tray 11 and a receiving tray 12. A first execution section and a second execution section for feeding the material strip 9 are set between the feeding tray 11 and the receiving tray 12 and along the conveying track of the material strip 9. The first execution section and the second execution section are respectively equipped with a patch feeding mechanism 2, a leveling and conveying mechanism 3, a rolling mechanism 7, and a detection and cutting mechanism 8 to complete patching, rolling, detection, and cutting correction of the material strip 9 during the conveying process.

[0068] The first execution section includes two parts: the main processing section and the power section. The main processing section is located in the extension direction of the output end of the feeding tray 11, while the extension direction of the power section is perpendicular to the extension direction of the second execution section's production line. The leveling and conveying mechanism 3 of the first execution section is located on the power section. After the material belt is fed into the power section, it is guided and conveyed to the power section by the reversing roller 6 at the end corner of the power section.

[0069] The length of the double-sided chip mounting equipment is related to the length of the second execution section, and the height of the double-sided chip mounting equipment is related to the length of the first execution section. In this embodiment, the first execution section is set in segments, which can reduce the height of the double-sided chip mounting equipment, help to reduce the volume, and make the overall structure of the equipment more compact.

[0070] The use of reversing rollers 6 between the execution sections takes up little space and helps to reduce the size of the equipment.

[0071] Furthermore, the feeding tray 11 and the receiving tray 12 are located on one side of the right-angled semi-enclosed area formed by the main processing section and the second execution section, reducing the space occupied by the feeding tray 11 and the receiving tray 12 outside the space enclosed by the first execution section and the second execution section, thus reducing the overall footprint of the equipment. This allows the equipment to be used in a smaller installation space.

[0072] The process of double-sided patch application in the two-stage execution section is as follows:

[0073] A protective film is covered on the material strip 9. The feeding tray 11 releases the protective film and the material strip 9 simultaneously. The protective film is guided to the take-up tray 12. The A side of the material strip is coated by the first execution section. The material strip is guided by the reversing roller 6 to the second execution section to complete the switching of the processed surface. The B side of the material strip is coated by the second execution section. The take-up tray 12 rewinds the protective film and the material strip with double-sided coating.

[0074] See attached document Figure 3 The chip feeding mechanism 2 is divided into two parts: a side-mounted chip feeding assembly 21 installed in the main processing section and a horizontal chip feeding assembly 22 installed in the second execution section. The side-mounted chip feeding assembly 21 and the horizontal chip feeding assembly 22 installed in the second execution section have the same component modules, but the relative positions of the components differ in their layout. The specific layout and relative positions are as follows:

[0075] See attached document Figure 5 The horizontal patch feeding assembly 22 includes a second feeding platform 220, a feeding bin and a drive bin arranged side by side on the second feeding platform 220. The feeding bin has a storage station, a tape receiving station and a material picking station. A second tape reel 222 is installed in the storage station area via a second tape shaft 227. The second tape reel 222 is installed on the second feeding platform 220 via the second tape shaft 227, and the second tape shaft 227 is perpendicular to the second feeding platform 220.

[0076] The second material gripping drive unit 226 drives the second material grabbing head 225 to grab the material placed on the second unfolding platform 223 and unfolded flat material belt under negative pressure. The second material gripping drive unit 226 drives the second material grabbing head 225 to reciprocate between the material grabbing station and the external feeding station. The second material grabbing head 225 grabs the material directly in front of the second unfolding platform 223 and feeds the material to the feeding station on the second execution section. The unfolding plane of the second unfolding platform 223 is parallel to the surface of the second feeding table 220.

[0077] The material tape after being collected is wound and stored by the second take-up reel 221 at the take-up station. The second take-up drive mechanism 228, which drives the second take-up reel 221, is set in the second protective box 224.

[0078] See attached document Figure 4 The side-mounted patch feeding assembly 21 includes a first feeding platform 210, on which a first feeding reel 212, a first take-up reel 211, a first spreading platform 213, a first protective box 214, a first picking gripper 215, and a first picking drive 216 are provided. The first take-up reel 211 is installed on the outside of the first protective box 214, and a first take-up drive mechanism 218 for driving the first take-up reel 211 is installed inside the first protective box 214.

[0079] The first tape reel 212 is mounted on the first feeding platform 210 via the first tape shaft 217, and the first tape shaft 217 is perpendicular to the first feeding platform 210. The first spreading platform 213 is vertically arranged, and the normal direction of the spreading end face of the first spreading platform 213 is perpendicular to the surface of the first feeding platform 210. The end face of the first protective box 214 used to install the first take-up reel 211 is parallel to the surface of the first feeding platform 210. The first gripping drive 216 drives the first picking gripper 215 to pick up material facing the first spreading platform 213 and to feed material to the loading station on the first execution section.

[0080] The first material gripping drive unit 216 and the second material gripping drive unit 226 adopt an XYZ three-axis linear electric slide module. The first tape take-up drive mechanism 218 and the second tape take-up drive mechanism 228 adopt one of the following combinations: a motor and a drive shaft, or a motor, a pulley, and a drive shaft. See the attached diagram for a specific implementation. Figure 6 .

[0081] By changing the relative positions of the components, the patch feeding mechanism on the vertical first execution section and the leveling and conveying mechanism 3 on the power section can be distributed in the same vertical space area, resulting in a more compact structure and smaller equipment size.

[0082] Specifically, as shown in the attached document Figure 7 Combined with appendix Figure 8As shown, the leveling and conveying mechanism 3 is used for power conveying of the material belt, including a set of tension rollers 31 arranged opposite each other, and a roller drive unit 32 for driving the tension rollers 31 to pull and move the material belt. The tension rollers 31 include a set of driving rollers 311 and driven rollers 312 arranged opposite each other. The driven rollers 312 are placed side by side on the driving rollers 311, and the material belt 9 moves through the gap between the driving rollers 311 and the driven rollers 312.

[0083] An adjustment mechanism 5 is provided on the conveying frame on one side of the tension roller group 31. The adjustment mechanism 5 includes a base 53 connected to the conveying frame of the execution section. A first adjustment member 51 and a second adjustment member 52 are provided in the base 53. The first adjustment member 51 and the second adjustment member 52 cooperate to adjust the rotation and tilt of the driven roller 312.

[0084] The active roller 311 is mounted on the output end of the roller drive unit 32 via a transmission assembly and is driven to move. The two sets of tension rollers 31 are respectively mounted on the conveyor frames on both sides of the execution section, and the two sets of tension rollers 31 are respectively matched with the transmission assembly and share a set of roller drive unit 32.

[0085] The roller drive unit 32 includes a drive motor 321, and the transmission assembly includes a long drive shaft 322 and a synchronous belt 323. The long drive shaft 322 is connected to the output shaft of the drive motor 321. The driving pulley of the synchronous belt 323 is mounted on the long drive shaft 322, and the driven pulley of the synchronous belt 323 is mounted on the first support shaft 313 of the driving roller 311. The driving roller 311 is coaxially mounted on the first support shaft 313.

[0086] Whether the material belt 9 is being conveyed normally or is stopped for processing, the drive roller 311 can rotate but does not tilt. Its angle is fixed and cannot be adjusted, and it always provides a small reverse tension to the material belt to keep the material belt taut.

[0087] In the initial state, the end planes of the driving roller 311 and the driven roller 312 are parallel to the running direction of the material belt, and there is no relative movement or rotation between the driven roller 312 and the material belt.

[0088] In operation, refer to the appendix. Figure 10 Rolling friction occurs between the driven roller 312 and the material belt 9, rolling the material belt 9. The end plane of the driven roller 312 rotates and tilts, intersecting the axis of the running direction of the material belt 9. The tilt angle of the end face of the driven roller is adjusted by the cooperation of the first adjusting member 51 and the second adjusting member 52 (the angle is adjusted before operation), so that the material belts on the upstream and downstream sides of the leveling conveyor mechanism 3 are conveyed in opposite states of tension and relaxation.

[0089] The direction of material belt movement on the execution section is set as the X-axis direction, the direction perpendicular to the execution section and from one side of the conveyor frame to the other side of the conveyor frame is set as the Y-axis direction, and the direction vertically upward perpendicular to the XY plane is set as the Z-axis direction.

[0090] In detail, as shown in the attached document Figure 9 As shown, a specific embodiment is given. The driven roller 312 is arranged along the Y-axis and mounted on the base 53 via the second support shaft 314. The first adjusting member 51 and the second adjusting member 52 are arranged on opposite sides of the driven roller 312 and push the driven roller 312 along the X-axis respectively, so that the driven roller 312 rotates and tilts, so that the resultant force on the material strip has components on the X-axis and Y-axis, so as to pull and flatten the material strip. The pushing directions of the first adjusting member 51 and the second adjusting member 52 are opposite, and they reset each other. After being reset to the initial state, they can continue to push and move along the reset pushing direction.

[0091] For example, the first adjusting member 51 pushes vertically along the X-axis towards the second support shaft 314 where the driven roller 312 is located. The second support shaft 314 rotates, causing the driven roller 312 to tilt. After the driven rollers 312 on both sides rotate, they form an inverted "V" shape. (See attached diagram.) Figure 11 The greater the pushing distance of the first adjusting member 51 along the X-axis, the larger the angle between the end plane of the driven roller 312 and the straight line containing the X-axis, and the greater the component force on the material belt along the Y-axis. The component force generated by the resultant force straightens and tightens the material belt, but will not damage the material belt or its circuits and devices. The specific magnitude of the force depends on the specific situation, and is specifically related to the weight of the driven roller 312, the friction between the material belt 9 and the upper and lower rollers, and the limit force at which the material belt begins to be damaged after being straightened.

[0092] Similarly, the second adjusting member 52 moves along the negative X-axis direction, which is opposite to the moving pushing direction of the first adjusting member 51. Therefore, the first adjusting member 51 and the second adjusting member 52 are equivalent to resetting each other, and after being reset to the initial state, they can continue to push and move along the reset pushing direction.

[0093] The stretching unit 4 is used to straighten and tension the material belt entering or leaving the execution section. The stretching unit 4 includes an adjusting roller 41 and a leveling power component 42. The leveling power component 42 drives the adjusting roller 41 to move in the direction that makes the material belt in the opposite state to the current state, so that there is an interaction force between the adjusting roller 41 and the material belt, so as to keep the belt surface flat during the material belt conveying process.

[0094] The leveling power assembly 42 drives the adjusting roller 41 to move and maintains an interaction force between the adjusting roller 41 and the material belt. The following provides a specific embodiment of the leveling power assembly 42 driving the adjusting roller 41 to make reciprocating linear movements.

[0095] In one or other embodiments, as shown in the appendix Figure 12 and appendix Figure 13 As shown, the leveling power component 42 is configured as a pulley combination scheme.

[0096] The leveling power assembly 42 includes a fixed pulley 421, a traction winding 422, and a moving track 424 for raising and lowering the adjusting roller 41. One side of the traction winding 422 is connected to a counterweight 423, and the other side is connected to the adjusting roller 41. The material belt passes over the bottom of the adjusting roller 41.

[0097] The traction force on the material belt 9 is dynamically balanced with the gravity of the adjusting roller 41 and the gravity of the counterweight 423 on the other side, so that the adjusting roller 41 can move up and down and always be in contact with the material belt and have an interaction force.

[0098] Specifically, the adjusting roller 41 is mounted on the movable plate seat 426 of the moving track 424 via the supporting central shaft 425, and the traction winding 422 is connected to the movable plate seat 426 via the traction roller 427. The traction roller 427 moves in the vertical direction and drives the movable plate seat 426 and the adjusting roller 41 to move up and down synchronously.

[0099] Based on the leveling and conveying mechanism 3, the reversing roller 6, and the stretching unit 4 provided above. The reversing roller 6 adopts a combination of gear 601 and motor 602, which cooperates with the side holes on the material belt.

[0100] Provides a power and tension combination for a system device: see attached document. Figure 1 The reversing roller 6 is a non-powered reversing roller. Non-powered reversing rollers are set at both ends of the first execution section. The non-powered reversing rollers only play a reversing role and do not provide power. In this scenario, the leveling and conveying mechanism 3 corresponding to the first and second execution sections provides power and can tension and level the material.

[0101] Another system equipment point power and tension combination is provided: see appendix. Figure 15 As shown, the reversing roller 6 is a power reversing roller. Power reversing rollers are set at both ends of the first execution section. The power reversing rollers play the role of reversing and transmission. In this scenario, the leveling and conveying mechanism 3 corresponding to the first execution section is omitted. Among them, the power reversing roller at the feeding end of the first execution section is equipped with a magnetic powder clutch 603 at the drive end. The magnetic powder clutch is an electromechanical control element based on electromagnetic principle and magnetic powder to transmit torque. The torque output is controlled by adjusting the magnitude of the excitation current. The power reversing roller at the unloading end of the first execution section rotates forward to transmit materials. Under the action of the magnetic powder clutch, the power reversing roller at the feeding end of the first execution section controls the motor 602 to rotate in reverse, providing a small reaction force, which can pull and tension the material belt.

[0102] See attached document Figure 14The rolling mechanism 7 includes a rolling roller 71, a cylinder assembly 72 that drives the rolling roller 71 to move in three-dimensional space, and a rotation drive 73 that drives the rolling roller 71 to rotate. The cylinder assembly 72 drives the rolling roller 71 to move up and down and horizontally, and the rotation drive 73 drives the rolling roller 71 to abut against the chip and roll along the direction perpendicular to the material strip's movement trajectory, so that the chip is firmly adhered to the material strip. A support platform 74 is provided at the bottom of the conveyor frame of the execution section. The support platform 74 is lifted up by a lifting assembly 75 to support the material strip, thereby cooperating with the rolling roller 71 to roll the chip and the material strip, so that the chip is firmly adhered to the material strip.

[0103] Inspection and cutting mechanisms 8 are respectively installed on the main processing section and the second execution section. The inspection and cutting mechanisms 8 are located downstream of the rolling mechanism 7 to detect whether the material strip patch is qualified and to cut off the unqualified patch section.

[0104] See attached document Figure 2 The inspection and cutting mechanism 8 includes an inspection camera installed at the inspection station and a cutting assembly installed at the cutting station, which is located downstream of the inspection station. The cutting assembly includes a punching blade, a receiving plate for punching, and a cutting power component. As the strip passes over the surface of the receiving plate, the cutting power component drives the punching blade downward to punch away the areas on the strip where the patch is defective, based on the inspection result from the inspection camera.
