[0039] This embodiment provides a tape sticking device, as Figures 1 - 4 shown, which includes a driving module 200 and a plurality of tape sticking heads. The tape sticking head includes a bottom plate 121, a transmission assembly 124, a traction assembly 126 and a tape sticking roller 125. The bottom plate 121 is connected to the output end of the driving module 200. The transmission assembly 124 includes a first gear 1242, a second gear 1243 and an intermediate gear 1241 that are all rotatably connected to the bottom plate 121. The first gear 1242 and the second gear 1243 are respectively meshed and connected with the intermediate gear 1241. The traction assembly 126 includes a first roller 1261 and a second roller 1262. The first roller 1261 is connected to the gear shaft of the second gear 1243, and the second roller 1262 is rotatably connected to the bottom plate 121. The tape is clamped between the first roller 1261 and the second roller 1262. The tape sticking roller 125 is connected to the gear shaft of the first gear 1242. The tape sticking roller 125 is used to stick the tape tightly to the structure to be pasted. The tape sticking rollers 125 of the plurality of tape sticking heads correspond to the plurality of structures to be pasted one by one.

[0040] The transmission assembly 124, the traction assembly 126 and the tape sticking roller 125 are all installed on the bottom plate 121. The driving module 200 drives the tape sticking head to move so as to drive the tape sticking roller 125 to move. The contact between the tape sticking roller 125 and the structure to be pasted generates frictional force to drive the tape sticking roller 125 to rotate. The tape sticking roller 125 drives the first gear 1242 to rotate. The first gear 1242 drives the second gear 1243 to rotate synchronously through the intermediate gear 1241, so as to drive the first roller 1261 to rotate. The clamping between the first roller 1261 and the second roller 1262 generates frictional force to drive the second roller 1262 to rotate, so that the traction assembly 126 pulls out the tape to the tape sticking roller 125. The traction assembly 126 can pull out the tape without a driving structure, with low cost, compact structure, small occupied space, and can be used for simultaneous sticking of multiple tapes, improving the production capacity and being more suitable for the situation where the distance between the structures to be pasted of the product is relatively small. And the gear transmission has high precision, improving the pasting precision.

[0041] The number of teeth of the first gear 1242 is the same as that of the second gear 1243, ensuring that the rotation speeds of the first roller 1261 and the tape - applying roller 125 are the same, and ensuring that the tape pulled out by the traction assembly 126 is exactly applied to the structure to be applied by the tape - applying roller 125. The number of teeth of the first gear 1242, the second gear 1243, and the intermediate gear 1241 are all the same, making the structure more compact.

[0042] The traction assembly 126 further includes a mounting plate 1263 and an elastic member 1264. The mounting plate 1263 is rotatably connected to the bottom plate 121. One end of the mounting plate 1263 is rotatably connected to a second roller 1262, and the other end is connected to the bottom plate 121 through the elastic member 1264. When the elastic member 1264 deforms, the first roller 1261 and the second roller 1262 are separated. Optionally, the elastic member 1264 is a spring. When the tape is initially loaded, the mounting plate 1263 is pressed to compress the spring, separating the first roller 1261 and the second roller 1262. The tape is placed between the first roller 1261 and the second roller 1262, and then the mounting plate 1263 is released, and the spring resets, clamping the tape between the first roller 1261 and the second roller 1262. The traction assembly 126 further includes a screw. The stud of the screw is connected to the bottom plate 121, and the middle part of the stud is rotatably connected to the mounting plate 1263, and the mounting plate 1263 is clamped between the end cap of the screw and the mounting plate 1263.

[0043] The tape - applying head further includes a cutting assembly 123, a cutting driving member, and a cutting knife 1232 connected to the output end of the cutting driving member. The cutting knife 1232 can extend between the first roller 1261 and the tape - applying roller 125 for cutting the tape between the traction assembly 126 and the tape - applying roller 125. Optionally, the cutting driving member is a cylinder 1231, and the cylinder 1231 is mounted on the bottom plate 121. When applying the tape, the traction assembly 126 pulls the tape to the tape - applying roller 125. The tape - applying roller 125 is located at the starting point of product application. The tape - applying head moves and reaches the cutting point. The cutting assembly 123 cuts the tape, and the tape - applying head continues to move. The tape - applying roller 125 rolls the tail tape, and simultaneously determines the position of the tape head.

[0044] The tape - applying head further includes a tape positioning block 128 connected to the bottom plate 121. The tape positioning block 128 is provided with a positioning groove 1281 for positioning the tape in the width direction. The positioning groove 1281 is located between the tape - applying roller 125 and the traction assembly 126. The tape positioning block 128 is further provided with a slot 1282. The cutting knife 1232 of the cutting assembly 123 can extend into the slot 1282 to limit the cutting knife 1232, ensuring the cutting accuracy of the tape. The slot 1282 communicates with the positioning groove 1281.

[0045] In some embodiments, the structure to be pasted, such as a gold finger, cannot be adhered with glue. Therefore, half of the tape is a non-adhesive area and half is an adhesive area. The upper side of the tape is the non-adhesive area, and the lower side is half non-adhesive area and half adhesive area. The upper side faces the first roller 1261 and the tape pasting roller 125, and the lower side faces the second roller 1262 and the structure to be pasted. An anti-adhesive layer is provided on the outer side of the second roller 1262 to prevent the tape from adhering to the second roller 1262. The first roller 1261 and the tape pasting roller 125 are rubber-coated rollers to increase the friction between the tape and the first roller 1261 and the tape pasting roller 125. The anti-adhesive layer can be made of a material that does not adhere to the tape in the prior art, and there is no limitation.

[0046] The tape pasting head further includes a guiding roller 127 rotatably connected to the bottom plate 121, and the guiding roller 127 is used to guide the tape on the material tray to the traction assembly 126.

[0047] The tape pasting device further includes a support assembly 150, a driving assembly 130 connected to the support assembly 150, a lead screw assembly 140, and three tape pasting heads. The support assembly 150 includes two fixing plates 154 and a guiding rod 152 connecting the two fixing plates 154. The lead screw assembly 140 includes a left-right hand lead screw 141, a left-handed nut 142, and a right-handed nut 143. The left-right hand lead screw 141 is rotatably connected to the two fixing plates 154 and is drivingly connected to the driving assembly 130. The left-right hand lead screw 141 includes a left-handed thread section, a middle section, and a right-handed thread section connected in sequence. The left-handed nut 142 is connected to the left-handed thread section, and the right-handed nut 143 is connected to the right-handed thread section. The tape pasting head is used to paste the tape tightly on the structure to be pasted. The three tape pasting heads are divided into two first tape pasting heads 120 and one second tape pasting head 170. The three tape pasting heads are all slidably connected to the guiding rod 152. The two first tape pasting heads 120 are correspondingly connected to the left-handed nut 142 and the right-handed nut 143. The second tape pasting head 170 passes through the middle section to keep the relative position of the second tape pasting head 170 and the left-right hand lead screw 141 unchanged, that is, to keep the position centered. Specifically, the bottom plates 121 of the two first tape pasting heads 120 are correspondingly connected to the left-handed nut 142 and the right-handed nut 143, and the bottom plate 121 of the second tape pasting head 170 passes through the middle section. In this embodiment, the first tape pasting head 120 and the second tape pasting head 170 only have differences in the structure of the bottom plate 121, and other structures are the same. The bottom plate 121 of the first tape pasting head 120 can install the left-handed nut 142 or the right-handed nut 143, and the bottom plate 121 of the second tape pasting head 170 is provided with an avoidance hole for avoiding the left-right hand lead screw 141. An oil-free bushing 122 is also installed on the bottom plate 121, and the guiding rod 152 is slidably connected to the bottom plate 121 through the oil-free bushing 122.

[0048] The driving assembly 130 drives the left - right screw 141 to rotate, driving the left - hand nut 142 and the right - hand nut 143 to move towards or away from each other, so as to realize the movement of the two first tape - sticking heads 120 towards or away from each other with the second tape - sticking head 170 as the center. During use, according to the spacing of different structures to be pasted, the driving assembly 130 drives the left - right screw 141 to rotate, adjusts the spacing between the two first tape - sticking heads 120 and the second tape - sticking head 170, ensures that the three tape - sticking heads and the three structures to be pasted are in one - to - one correspondence, so that the three tape - sticking heads are applicable to different spacings of the structures to be pasted. The tape - sticking device realizes multi - station and variable - pitch tape sticking, improves production efficiency, thus increasing production capacity, and can be flexibly adjusted according to different spacings of products, improving applicability. The left - right screw 141 has high adjustment accuracy, ensuring the pasting accuracy of the tape on the structure to be pasted. The tape - sticking device can be used for PCBs, especially for pasting tapes to shield the gold fingers of PCBs before printing.

[0049] The driving assembly 130 includes a motor 131, a coupling 133 and a mounting rod 132; the motor 131 is mounted on one of the fixing plates 154 through the mounting rod 132, and the motor 131 is connected to one end of the left - right screw 141 through the coupling 133. When the motor 131 rotates forward, the spacing between the tape - sticking heads is reduced; when the motor 131 rotates in reverse, the spacing between the tape - sticking heads is increased.

[0050] The lead of the left - hand thread section and the right - hand thread section is the same, ensuring that the moving distances of the two first tape - sticking heads 120 and the second tape - sticking head 170 are the same, and the spacing formed by the two first tape - sticking heads 120 and the second tape - sticking head 170 is the same, which is applicable to the structures to be pasted arranged at uniform intervals.

[0051] There are at least two parallel guide rods 152 between the two fixing plates 154. All at least two guide rods 152 are slidably connected to the three tape - sticking heads. The three tape - sticking heads are stably mounted, and the two first tape - sticking heads 120 can move smoothly along the guide rods 152. In this embodiment, two guide rods 152 are provided, with a simple and reliable structure. The three tape - sticking heads are arranged between the two fixing plates 154.

[0052] The second tape - sticking head 170 is rotatably connected to the middle section, or the second tape - sticking head 170 is provided with an avoidance hole, and the middle section passes through the avoidance hole, so that the second tape - sticking head 170 can keep its position unchanged when the left - right screw 141 rotates.

[0053] Such as Figure 4 and Figure 5As shown, the taping device further includes a limit assembly 160 that limits the extreme position of the first taping head 120 within an adjustable range. The limit assembly 160 includes a centering adjustment plate 161 and two limit members 162. The centering adjustment plate 161 is provided with two limit sliding grooves 1611. The centering adjustment plate 161 is connected to the second taping head 170. The two limit members 162 are correspondingly connected to the two first taping heads 120, and the two limit members 162 are correspondingly slidably connected to the two limit sliding grooves 1611. The limit sliding grooves 1611 limit the movable range of the first taping head 120. Specifically, the limit member 162 is a bolt. The limit assembly 160 includes three bolts of the same height. The centering adjustment plate 161 is connected to the bottom plate 121 of the second taping head 170 by bolts. The other two bolts are connected to the bottom plates 121 of the two first taping heads 120. The rod portions of the bolts are slidably connected to the limit sliding grooves 1611, and the bolt end caps abut against the centering adjustment plate 161.

[0054] The support assembly 150 further includes a cross plate 151, a vertical plate 156, and a lead screw support 155. The cross plate 151 is connected to the fixed plate 154 through the vertical plate 156. The left and right hand lead screw 141 is rotatably connected to the lead screw support 155 and is connected to the fixed plate 154 through the lead screw support 155. The support assembly 150, the reel assembly 110 installed on the cross plate 151, the three taping heads installed on the guide rod 152, the drive assembly 130 installed on the fixed plate 154, the lead screw assembly 140 installed on the two fixed plates 154, and the limit assembly 160 form a taping module 100. The cross plate 151 of the support assembly 150 is connected to the output end of the drive module 200 through a connecting flange 153.

[0055] As Figure 4 shown, the taping module 100 further includes three reels. The three reels are respectively used for supplying tape to the three taping heads. The three reels are connected to the cross plate 151 in parallel along the extending direction of the guide rod 152. The drive assembly 130 is connected to the fixed plate 154. The three reels supply materials independently without interference, and can be applicable to simultaneous taping of one or two or three structures to be taped.

[0056] The tray includes two sets of tray components 110. The tray component 110 includes a driven shaft 114, a tape roll clamping plate 115, and a tape roll bracket 116. The tape roll bracket 116 is connected to the cross plate 151. One end of the driven shaft 114 is rotatably connected to the tape roll clamping plate 115, and the outer periphery of the other end is elastically connected to the installation groove of the tape roll bracket 116. The tape roll bracket 116 is provided with a notch 1161 for communicating the installation groove with the outside. The width of the notch 1161 is not less than the outer diameter of the driven shaft 114. The driven shaft 114 is elastically connected to the installation groove, and the tape roll body 113 wound with the tape is clamped between the tape roll clamping plates 115 of the two sets of tray components 110. When replacing the tape roll body 113, the driven shaft 114 is pulled out from the notch 1161 under the action of an external force, so that the driven shaft 114, the tape roll clamping plate 115, and the tape winding core of the tape roll body 113 are pulled out simultaneously. The tape roll clamping plates 115 of the two sets of tray components 110 are opened, the core of the tape roll body 113 is taken out, the new tape roll body 113 is clamped between the two tape roll clamping plates 115, and then the driven shaft 114 is installed in the installation groove of the tape roll bracket 116 through the notch 1161. By adopting the above structure, it is convenient to replace the tape. By setting the installation groove, it is convenient to install the driven shaft 114.

The spring is arranged between the check screw 111 and the spring pin 112. The spring pin 112 abuts against the outer periphery of the driven shaft 114. By adjusting the check screw 111, the pre-tightening force on the driven shaft 114 is adjusted to achieve the rotational damping effect on the tape roll bracket 116.

[0058] The circumferential direction of the driven shaft 114 is provided with a limiting groove 1141. The spring pin 112 abuts against the limiting groove 1141 to prevent the driven shaft 114 from sliding axially in the tape roll bracket 116 along the axial direction of the driven shaft 114. In this embodiment, there are three sets of check screws 111, springs, and spring pins 112. The three spring pins 112 are evenly spaced. By increasing the number of spring pins 112, the contact area with the driven shaft 114 is increased, thereby improving the connection reliability and preventing the driven shaft 114 from slipping off.

[0059] The circumferential direction of the driven shaft 114 is provided with a limiting piece 1142. The limiting piece 1142 abuts against the side surface of the tape roll clamping plate 115 to achieve axial limiting.
