[0064] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0065] like Figure 1 As shown, a single-sided patch device includes a film-coated material strip mechanism 3, a material strip processing section 4 and a material strip power mechanism. The processing equipment is installed along the side of the material strip processing section 4 to process the material strip. The processing equipment includes a counting mechanism 8, a patch feeding mechanism 5, a rolling mechanism 6 and a detection and cutting mechanism 9. The material strip is fed from the feeding end to the material strip processing section 4. During the conveying process, the material strip is subjected to the processing actions of patch, rolling, detection and cutting. In the process of processing, the counting mechanism 8 is used to accurately calculate the processing length and the remaining material amount of the material strip so as to replace new materials in time.

[0066] The laminating material belt mechanism 3 includes a material discharging tray 31 and a material receiving tray 32, and a first rotary drive member 33 and a second rotary drive member 34 for correspondingly driving the material discharging tray 31 and the material receiving tray 32 to move;

[0067] The material tape 36 is wound around the unwinding tray 31 or the receiving tray 32 and covered with a coating 35 to provide a spacer between adjacent material tapes 36 to avoid direct contact and friction between the material tapes, thereby preventing damage to circuits or components and protecting the material tape 36 .

[0068] After the unloading tray 31 releases the double-layered material strip-film, the material strip 36 is guided to the material strip processing section 4 through a plurality of guide rollers, and then to the material receiving tray 32 through a plurality of guide rollers. After the material strip 36 is transported through the material strip processing section 4 and processed, it is guided to the recycling tray 32, and the film 35 covers the material strip 36 again, and the material strip 36 and the film 35 are synchronously wound up by the material receiving tray 32. Therefore, the unloading tray and the material receiving tray 32 cooperate to synchronously release the unprocessed material strip and wind up the processed material strip and the protective film 35 thereon.

[0069] Several photoelectric sensors are installed on the sides of the discharge tray 31 and the receiving tray 32. The photoelectric sensors are arranged on the conveying path of the material belt, including the area where the material belt sags due to relaxation. The receiving tray 32 reels the material belt according to the state of the material belt detected by the photoelectric sensors. For example, in the area where the material belt sags due to relaxation, the distance between the upper and lower photoelectric sensor detection positions increases, indicating that the length of the relaxed and drooping material belt increases, and the material belt needs to be reeled in to avoid the material belt drooping too long. Therefore, according to the detection results of the photoelectric sensors, the power mechanism of the receiving tray can be controlled to drive the receiving tray 32 to reel the material belt. In addition, in the unpowered state, the discharge tray 31 can be manually rotated to release the material belt, and the receiving tray 32 can be manually rotated to reel the material belt.

[0070] As attached Figure 2 As shown, the material belt between the unloading tray 31 and the receiving tray 32 moves along the material belt processing section 4. A set of material belt power mechanisms are provided at the feeding end and the unloading end of the material belt processing section 4, namely, the first material belt power mechanism 1 and the second material belt power mechanism 2. Figure 3 The two cooperate to drive the material belt to move from the loading end to the unloading end. After loading, the chip is pasted on the material belt through the patch feeding mechanism 5, and the rolling mechanism 6 arranged downstream of the patch feeding mechanism 5 is used to roll the part of the material belt where the chip is pasted, so that the chip is loaded firmly.

[0071] The moving direction of the material belt on the material belt processing section 4 is set as the X-axis direction, the direction perpendicular to the material belt processing section and pointing from one side conveying frame of the material belt processing section 4 to the other side conveying frame is set as the Y-axis direction, and the vertical upward direction perpendicular to the XY plane is set as the Z-axis direction.

[0072] The first material belt power mechanism 1 and the second material belt power mechanism 2 are separately arranged. In specific implementation, the structural principles can be the same or different. Fig.10 The operation diagram of the second material belt power mechanism 2 conveying the material belt is shown in the attached figure. Figure 8 The first material belt power mechanism 1 pulls the material belt along the X-axis direction, and the second material belt power mechanism 2 provides a pull-back force in the opposite direction of the X-axis. The pull-back force provided by the first material belt power mechanism 1 is greater than the pull-back force in the opposite direction provided by the second material belt power mechanism 2, so that the material belt moves along the X-axis direction as a whole.

[0073] In this way, during the movement of the material strip 36 along the X-axis direction, even if the material strip stops to be processed, it is always subjected to a reverse pulling force to keep the material strip flat and not bent.

[0074] In this embodiment, the first material belt power mechanism 1 and the second material belt power mechanism 2 are composed of the same physical structure: each of them is provided with a set of conveying drive mechanism 11 and two sets of stretching roller groups 12. The two sets of stretching roller groups 12 are respectively installed on the conveying frames on both sides of the material belt processing section 4, and the two sets of stretching roller groups 12 are respectively installed on the same set of conveying drive mechanism 11 through the transmission assembly 8. The conveying drive mechanism 11 drives the stretching roller group 12 to move through the transmission assembly (transmission long shaft 112, synchronous belt 113) to pull and move the material belt, ensuring that the stretching roller groups 12 on both sides move synchronously.

[0075] Specifically, as attached Figure 4 As shown, an adjustment mechanism 7 is provided on one side of the stretching roller group 12 , and the adjustment mechanism 7 includes a base 73 connected to the conveying frame of the material strip processing section 4 and a first adjustment member 71 and a second adjustment member 72 installed on the base 73 .

[0076] The stretching roller group 12 includes a group of active rollers 121 and driven rollers 122 which are arranged in parallel at the top and the bottom. The material belt 36 moves through the gap between the active rollers 121 and the driven rollers 122 .

[0077] The conveying drive mechanism 11 includes a driving motor 111, a transmission shaft 112 and a synchronous belt 113. The transmission shaft 112 is connected to the output shaft of the driving motor 111, the driving wheel of the synchronous belt 113 is installed on the transmission shaft 112, the driven wheel of the synchronous belt 113 is installed on the first support shaft 123 of the driving roller 121, the driving roller 121 is coaxially sleeved on the first support shaft 123, the driven roller 122 is arranged along the Y-axis direction, and is installed on the base 73 through the second support shaft 124.

[0078] Regardless of whether the material belt is being conveyed normally or stopped for processing, the active roller 121 can rotate but not tilt, and the angle is fixed and cannot be adjusted. It always provides a small reverse pulling force to the material belt to keep the material belt taut.

[0079] In the initial state, the end planes of the active roller 121 and the driven roller 122 are parallel to the running direction of the material belt, and there is no relative movement or rotation between the driven roller 122 and the material belt.

[0080] The end plane of the driven roller 122 rotates and tilts to intersect with the axis of the running direction of the material belt. The inclination angle of the end face of the driven roller 122 is adjusted by the cooperation of the first adjusting member 71 and the second adjusting member 72 (the angle is adjusted before operation).

[0081] In the running state, rolling friction occurs between the first leveling member 12 and the material strip, and the first leveling member 12 rotates and rolls the material strip.

[0082] As attached Figure 7 As shown in FIG. 1 , the first adjusting member 71 and the second adjusting member 72 are disposed on different sides of the driven roller 122 and push the driven roller 122 along the X-axis line respectively so that the driven roller 122 rotates and tilts.

[0083] The first adjusting member 71 vertically pushes the second support shaft 124 where the driven roller 122 is located along the X-axis direction, and the second support shaft 124 rotates, so that the driven roller 122 tilts. The greater the pushing distance of the first adjusting member 71 along the X-axis direction, the greater the angle between the end plane of the driven roller 122 and the straight line where the X-axis is located, and the greater the component force on the Y-axis on the material strip. The component force generated by the combined force straightens and tightens the material strip, but does not damage the material strip and the circuits and components on it. The specific force depends on the specific situation, which is related to the gravity of the driven roller 122, the friction between the material strip and the upper and lower rollers, and the limit force at which the material strip begins to be damaged after being straightened by force.

[0084] Similarly, the second adjusting member 72 moves along the negative direction of the X-axis, which is opposite to the moving pushing direction of the first adjusting member 71. Therefore, the first adjusting member 71 and the second adjusting member 72 are equivalent to resetting each other, and after resetting to the initial state, they can continue to push and move along the reset pushing direction.

[0085] The driven roller 122 at the feeding end or the unloading end is in the shape of an "eight" as a whole. The driven roller 122 is tilted in the first and third quadrants or the second and fourth quadrants of the XY plane. Correspondingly, in the operating state, the pair of first adjusting members 71 at the feeding end are in the shape of a positive "eight" or an inverted "eight", while the pair of first adjusting members 71 in the second material belt power mechanism 2 at the unloading end are always in the shape of an inverted "eight".

[0086] Refer to the attached Fig. 9 The total force on the strip has components on the X-axis and Y-axis, and the strip is pulled and flattened to prevent the strip from being uneven.

[0087] Wind devices 11 are provided at both ends of the material strip processing section 4 , and the wind devices 11 may be wind knives.

[0088] As attached Fig.11 As shown, the material strips on both sides of the material strip processing section 4 droop naturally, and during the material strip conveying process, the drooping amount of the material strips on both sides is in a dynamically changing state; the air outlet of the wind power device 11 is directly opposite to the inner end surface of the drooping bend of the material strip, and under the influence of wind force, the material strip droops and is tensioned, and, as the drooping height of the material strip changes, the wind power device 11 can be raised and lowered synchronously, and the distance between the air outlet of the wind power device 11 and the inner end surface of the vertical bend of the material strip is kept constant, so that the drooping material strips to be loaded at both ends of the material strip processing section 4 remain flat.

[0089] The material belt processing sections 4 are all equipped with material belt driving mechanisms, and the material belt driving mechanisms can keep the material belt flat while driving the material belt to move, thereby preventing the material belt from bending.

[0090] Among them, the patch feeding mechanism 5 is arranged at the feeding end of the material belt processing section and is located downstream of the first material belt power mechanism; and, there are two groups of patch feeding mechanisms 5, which are arranged in parallel and feed materials to the material belt alternately.

[0091] Specifically, as attached Figure 5 As shown, the chip loading mechanism 5 includes a grabbing head 51, a chip feeding roller 52, a chip waste roller 53, a material spreading platform 54, and a group of driving parts corresponding to the grabbing head 51, the chip feeding roller 52, the chip waste roller 53 and the material spreading platform 54.

[0092] The grabbing head 51 is driven to move in a three-dimensional space by a three-dimensional power module 55, and the grabbing head 51 grabs the chip by negative pressure suction. After grabbing the chip, the grabbing head 51 moves along the vertical conveying direction of the material belt, transfers the chip to the top of the material belt, and then moves downward to adhere the chip to the patch area of ​​the material belt. The material unrolling platform 54 is set as a glass table, unrolling and conveying the material roll released by the chip feeding roll 52, and the chip material roll is flatly attached to the glass table by negative pressure suction. The chip material roll carries the chip to be patched with adhesive on the back.

[0093] The material strip after the chips are removed is rolled up to the chip waste roll 53 , and the chip supply roll 52 and the chip waste roll 53 are driven by a motor.

[0094] The rolling mechanism 6 is arranged downstream of the patch feeding mechanism 5. Figure 6 The rolling mechanism 6 includes a rolling roller 61 and a cylinder assembly 62 for driving the rolling roller 61. The cylinder assembly 62 drives the rolling roller 61 to move up and down and horizontally. The rolling roller 61 abuts against the chip and rolls along the vertical X-axis direction, so that the chip is firmly bonded to the material belt. A supporting platform 60 is provided at the bottom of the conveying frame of the material belt processing section 4. The supporting platform 60 is lifted by a lifting assembly 64 to support the material belt, thereby cooperating with the rolling roller 61 to roll the chip and the material belt, so that the chip is firmly attached to the material belt.

[0095] As attached Figure 3 As shown in the figure, a counting mechanism 8 is also provided at the feeding end of the material belt processing section 4. The counting mechanism 8 is arranged downstream of the first material belt power mechanism 1, and includes a counting gear and a motor driving the counting gear to rotate. The teeth on the counting gear correspond to the side holes on the material belt one by one. The circumference of the counting gear and the number of teeth are fixed and known, and the spacing between adjacent side holes on the material belt is fixed and known. The counting gear rotates and counts the side holes, thereby accurately calculating the processing length of the material belt so as to replace the material in time.

[0096] In addition, the teeth do not correspond to the side holes, and the material belt is stuck in conveying, indicating that the material belt is skewed, and the material belt skew can be self-checked.

[0097] The counting gear rotates and rolls over the edge of the material strip. Only when the material strip is flat and without bends, and the teeth are aligned with the edge holes, can counting be performed. Therefore, the counting mechanism can further check and maintain the flatness of the material strip.

[0098] A detection and cutting mechanism 9 is also provided at the unloading end of the material strip processing section 4, which is located downstream of the rolling mechanism. Figure 2 The detection and cutting mechanism 9 includes a detection camera arranged at the detection station and a cutting assembly installed at the cutting station, and the cutting station is arranged downstream of the detection station.

[0099] The cutting assembly includes a punching knife, a receiving plate for punching, and a cutting power part. The material strip passes through the surface of the receiving plate. According to the detection results of the detection camera, the cutting power part drives the punching knife downward to punch out the unqualified area of ​​the patch on the material strip.

[0100] The processing equipment installed on the material strip processing section and its surroundings is divided into areas / modules, and a sliding module is arranged at the bottom.

[0101] The frames on both sides of the material strip processing section are supported and installed on the sliding module. By adjusting the spacing between the frames on both sides, it can adapt to the processing of material strips of different widths, such as 35 mm, 48 mm and 70 mm. Correspondingly, the position of the equipment around the section is adjusted to adapt to the processing of material strips of different rules, and the equipment application scenario compatibility is higher.
