Description
Technical Field
[0001] The utility model relates to the technical field of LED substrate gluing, in particular to an auxiliary tool for LED substrate gluing with adhesive tape which is easy to operate. Background Art
[0002] LED light sources require pre-processing before injection molding. One of these steps involves applying tape to the bottom of the LED substrate to prevent it from sticking to the resin during molding. Currently, this process is primarily performed manually by the operator: first, a length of tape is drawn out that exceeds the LED substrate. The effective center portion of the tape is then evenly applied to the bottom of the LED substrate. After application, the excess tape at both ends protrudes beyond the substrate. Finally, a cutter is used to remove the excess tape. The operator manually pulls the excess tape tight to allow the cutter to remove it. After removal, the excess tape adheres to the operator's hands, requiring additional time and effort to clean. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide an easy-to-operate auxiliary tool for taping LED substrates, which can ensure that excess tape will not stick to the operator's hands during taping, and the operator can clean up the excess tape uniformly after completing multiple tapings.
[0004] In order to solve the above technical problems, the utility model is an easy-to-operate LED substrate taping auxiliary tool, including a tape placement table, a tape guide is provided at the starting end of the tape placement table to guide the end of the tape placement table to the end of the tape placement table so that the tape is spread flat on the tape placement table for LED substrate pasting, and also includes a cutter, a pressure plate is provided at the end of the tape placement table, the pressure plate is pressed on the pasting surface of the excess part of the tape end, the cutter cuts off the excess part of the tape end, and the pressure plate is lifted to take away the excess part of the tape end.
[0005] Furthermore, the tape guide comprises a tape roll supporting cylinder, which supports the tape roll and guides the tape roll to rotate so that the free end of the tape roll faces the end of the tape placement platform.
[0006] Furthermore, the tape guide includes a pressure wheel, which presses the tape on the tape placement table, and the pressure wheel rotates to send the end of the tape to the end of the tape placement table.
[0007] Furthermore, the pressing plate is hinged to the tape placement table and is rotated and lifted to remove the excess portion of the tape end.
[0008] Furthermore, it includes a driving spring for driving the pressing plate to press the tape.
[0009] Furthermore, the adhesive tape placement table is specifically a negative pressure adsorption table for adsorbing the adhesive tape.
[0010] Furthermore, a substrate positioning member for lateral positioning of the LED substrate is installed on the tape placement table.
[0011] Furthermore, the substrate positioning member specifically limits the LED substrate laterally in at least two non-parallel directions to achieve lateral positioning of the LED substrate.
[0012] Furthermore, the substrate positioning piece is angular and rests on a corner of the LED substrate.
[0013] Furthermore, there are two opposite substrate positioning members that together laterally clamp the LED substrate.
[0014] During adhesive application, the tape guide guides the end of the tape to the end of the placement table so that the tape can be spread flat on the placement table. The pressure plate presses the excess tape end, and the LED substrate is attached to the tape. The cutter then cuts off the excess tape. After cutting, the excess tape is attached to the pressure plate. The pressure plate is lifted to remove the excess tape, so the excess tape does not stick to the operator's hands. Because the excess tape on the pressure plate does not significantly affect the pressure plate, the operator can start the next adhesive application without cleaning it. The excess tape on the pressure plate is cleaned after completing multiple adhesive applications, making it convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described in detail below in conjunction with specific embodiments.
[0024] LED substrate tape auxiliary tools see Figure 1 , including a tape placement table 1 and a negative pressure fan 100. The tape placement table 1 is a negative pressure adsorption table. The negative pressure fan 100 is connected to the tape placement table 1 to provide negative pressure for the tape placement table 1. A front guide slit 14 is left between the middle part 11 and the front end 12 of the tape placement table 1, and a rear guide slit 15 is left between the middle part 11 and the rear end 13. The front and rear guide slits 14, 15 are both in the left and right directions. A cutter 2 is installed on the left side of the tape placement table 1. The cutter 2 includes a handle 21 in the front and rear directions. The front and rear ends of the handle 21 are respectively inserted into the front and rear guide slits 14, 15, and are respectively equipped with right-facing blades 22, as shown in FIG. Figure 2 As shown. A pressure wheel 52 is rotatably mounted on the rear end 13 of the adhesive tape placement table 1, and the pressure wheel 52 presses on the top surface of the rear end 13; a pressure plate 6 is hingedly connected to the front end 12, as shown. Figure 4 The hinge shaft of the pressing plate 6 is provided with a torsion spring 60, which acts as a driving spring to apply a driving torque to the pressing plate 6 so that it presses against the top surface of the front end 12. Figure 1 , a tape roll support tube 51 is provided at the rear side of the tape placement table 1; the tape roll 90 is as shown Figure 3 , put it on the outside of the tape roll support tube 51, and in this way support it on the tape roll support tube 51. The operator's first tape application operation is as follows:
[0025] See Figure 3With the front-to-back direction as the longitudinal direction, the tape roll 90 is manually moved. The tape roll support tube 51 guides the tape roll 90 to rotate, causing the free end 905 of the tape roll 90 to be longitudinally fed forward, with the adhesive surface 901 of the free end 905 facing upward and the protective surface (not shown in the figure due to viewing angle) facing downward. The negative pressure fan 100 is activated to provide negative pressure to the tape placement table 1. The free end 905 of the tape roll 9 is then fed between the pressure roller 52 and the rear end 13 of the tape placement table 1, allowing the pressure roller 52 to press against the free end 905 of the tape roll 9. Because the tape placement table 1 absorbs the free end 905 of the tape roll 9 and the contact area between the pressure roller 52 and the adhesive surface 901 of the tape roll 90 is small, the tape roll 90 will not stick to the pressure roller 52. Rotating the pressure roller 52 overcomes the lateral friction between the protective surface of the tape roll 90 and the tape placement table 1, and the free end 905 of the tape roll 90 is longitudinally fed forward to the front side of the pressure roller 52. Manually lift the pressure plate 6 and pull the free end 905 of the tape roll 90 forward longitudinally to the front end 12 of the tape placement platform 1, thereby pulling out a length of tape 9 in the longitudinal direction. The rear end of the longitudinal tape 9 is connected to the tape roll 90 and serves as the starting end of the longitudinal tape 9. The free end 905 of the tape roll 90 serves as both the front end and the end of the longitudinal tape 9. Accordingly, the rear end 12 of the tape placement platform 1 serves as the starting end 101, and the front end 13 serves as the end 102. The front end 12 of the tape placement platform 1 is located at the end 102 of the tape placement platform 1, and the rear end 13 of the tape placement platform 1 is located at the starting end 101 of the tape placement platform 1. The tape roll support cylinder 51 and the pressure wheel 52 are both located at the starting end 101 of the tape placement platform 1, and both serve as tape guides. The tape roll support cylinder 51 guides the tape roll 90 to rotate so that the free end 905 of the tape roll 90 faces the end 102 of the tape placement platform 1, thereby guiding the free end 905 of the tape roll 90 to the end 102 of the tape placement platform 1. The pressure wheel 52 sends the free end 905 of the tape roll 90 forward, thereby guiding the free end 905 of the tape roll 90 to the end 102 of the tape placement platform 1. The tape placement platform 1 serves as a tape placement platform, and the longitudinal tape 9 is laid flat on it; the middle portion 11 of the tape placement platform 1 absorbs the protective surface of the effective middle portion 91 of the longitudinal tape 9, the front end 12 absorbs the protective surface of the excess portion 92 of the front end of the longitudinal tape 9, and the rear end 13 absorbs the protective surface of the excess portion 93 of the rear end of the longitudinal tape 9, so that the longitudinal tape 9 remains flat. See Figure 4 , put down the pressing plate 6, which is driven by the torsion spring 60 to press onto the adhesive surface 921 of the excess portion 92 at the front end of the longitudinal tape 9, and the preparation work is completed.
[0026] See Figure 5 , stick the LED ceramic substrate 8 to the sticking surface 911 of the middle effective part 91 of the longitudinal tape 9 (see Figure 3) during this process, the tape placement platform 1 absorbs the longitudinal tape 9 to keep it flat, preventing it from curling or wrinkling, thus improving the adhesive firmness and flatness. After pasting, the excess portions 92 and 93 at the front and rear ends of the longitudinal tape 9 extend from the edge of the LED ceramic substrate 8 to the front and rear sides of the LED ceramic substrate 8. Figure 7 , with the left and right directions as the horizontal direction, pull the handle 21 of the cutter 2 to the right horizontally so that the cutter 2 moves along the front and rear guide slits 14 and 15 (see Figure 1 ) moves horizontally to the right, driving the two blades 22 to pass through the front and rear ends of the middle part 1, thereby cutting off the excess parts 92 and 93 of the front and rear ends of the tape 9, respectively. Then, the cutter 2 is reset to the left. After that, the excess part 93 at the rear end of the tape 9 serves as the new free end 93 of the tape roll 90. Because the adhesive force between the effective part 91 of the tape 9 and the LED ceramic substrate 8 is stronger than the negative pressure adsorption force, and the adhesive force between the excess part 92 at the front end of the tape and the pressure plate 6 is stronger than the negative pressure adsorption force, there is no need to stop the negative pressure fan 100. The LED ceramic substrate 8 and the effective part 91 of the tape 9 adhered thereto can be directly picked up by hand to separate the LED ceramic substrate 8 (see Figure 3 ) are removed together, and then the pressing plate 6 is directly rotated and lifted by hand so that the pressing plate 6 moves upward away from the front end 12 of the tape placement table 1. The pressing plate 6 will take away the excess part 92 of the front end of the tape pasted thereon, and the work of pasting the tape 9 is completed.
[0027] See Figure 4 and Figure 7 The excess portion 92 of the tape 9 at the front end is stuck to the pressing plate 6 and will not stick to the operator's hands or significantly affect the pressing plate 6. Therefore, the operator can proceed directly to the next adhesive application without cleaning it. The pressing plate 6 remains raised, and the operator then pulls the new free end 93 of the tape roll 90 forward to the front end 12 of the tape placement table 1, thereby pulling out another longitudinal section of tape in the front-to-back direction. The subsequent operations are the same as when applying the tape 9 for the first time and will not be described in detail. The operator cleans the excess portion 92 of the tape 9 at the front end of the pressing plate 6 after completing multiple adhesive applications, which is convenient.
[0028] See Figure 5 During the pasting process, if the operator manually holds the LED ceramic substrate 8 to position it, it is easy for the longitudinal tape 9 to be misplaced due to hand shaking or visual errors. In order to improve the pasting accuracy of the longitudinal tape 9, two front and rear substrate positioning units 31 and 32 are installed on the tape placement table 1. The front and rear substrate positioning units 31 and 32 jointly clamp the LED ceramic substrate 8 and perform lateral positioning on the LED ceramic substrate 8 to assist in improving the pasting accuracy of the longitudinal tape 9. The front and rear substrate positioning units 31 and 32 are symmetrical in structure. The following is a detailed description of the front substrate positioning unit 31 as an example. The substrate positioning unit 31 is shown in FIG. Figure 6, including a mounting block 33, which is mounted on the side wall of the front end 12 of the adhesive tape placement table 1, and has a mounting hole in the front-to-back direction (not shown in the figure due to viewing angle), through which a sliding rod 34 is passed, with the front and rear ends 341 and 342 of the sliding rod 34 extending out of the mounting hole respectively. The front end 341 of the sliding rod 34 is larger than the mounting hole and cannot pass through the mounting hole backward; the rear end 342 of the sliding rod 34 is mounted with a substrate positioning member 3; a positioning spring 35 is sleeved on the sliding rod 34, and the positioning spring 35 pushes the substrate positioning member 3 backward. The substrate positioning member 3 is shown Figure 8 , is a right-angled shape, with a rearward-facing first positioning surface 301 and a leftward-facing second positioning surface 302. The top edge of the first positioning surface 301 is chamfered to form a downward-sloping first guide surface 303, and the top edge of the second positioning surface 302 is chamfered to form a downward-sloping second guide surface 304. The center portion of the substrate positioning member 3 is left hollow to form a buckle groove 300. The rear substrate positioning unit 32 is symmetrical with the front substrate positioning unit 31 in structure and will not be described in detail. The operator chooses one of the following two methods to lateral position the LED ceramic substrate 8:
[0029] (1) See Figure 5 and Figure 6 First, align the front right corner 81 and rear right corner 82 of the LED ceramic substrate 8 with the two substrate positioning members 3 of the front and rear substrate positioning units 31 and 32, respectively. Then, press the front right corner 81 and rear right corner 82 of the LED ceramic substrate 8 between the two substrate positioning members 3. If the LED ceramic substrate 8 is positioned forward, the front edge 801 of the LED ceramic substrate 8 will push against the first guide surface 303 of the forward substrate positioning member 3. The first guide surface 303 of the substrate positioning member 3 guides the front edge 801 of the LED ceramic substrate 8 downward and backward toward the first positioning surface 301. At the same time, the substrate positioning member 3 is pushed forward by the LED ceramic substrate 8, driving the sliding rod 34 to slide forward together, thereby compressing the positioning spring 35. The positioning spring 35 then indirectly applies a backward thrust to the front edge 801 of the LED ceramic substrate 8 through the substrate positioning member 3. Simply loosen the LED ceramic substrate 8 slightly, and the positioning spring 35 will push the LED ceramic substrate 8 backward to the correct position. Similarly, if the LED ceramic substrate 8 is positioned at the rear, the positioning spring 35 of the rear substrate positioning unit 32 pushes the LED ceramic substrate 8 forward to the correct position, which will not be described in detail. Figure 6 and Figure 8If the LED ceramic substrate 8 is positioned to the right, its right edge 803 will push against the second guide surface 304 of the substrate positioning member 3. This guide surface 304 guides the LED ceramic substrate 8 downward and leftward toward the second positioning surface 302, thereby positioning the LED ceramic substrate 8 in the correct position. Slightly loosen the LED ceramic substrate 8, then manually push it to the right, ensuring that its right edge 803 is in contact with the substrate positioning member 3. In this state, the two substrate positioning members 3 of the front and rear substrate positioning units 31 and 32 rest against the opposite front right corner 81 and rear right corner 82 of the LED ceramic substrate 8, respectively, jointly clamping the LED ceramic substrate 8 laterally. The front substrate positioning member 3 laterally restrains the LED ceramic substrate 8 in the front and right directions, thereby achieving lateral positioning of the LED ceramic substrate 8. The rear substrate positioning member 3 laterally restrains the LED ceramic substrate 8 in the rear and right directions, thereby achieving lateral positioning of the LED ceramic substrate 8.
[0030] (2) See Figure 8 First, insert your finger into the buckle groove 300 of the front substrate positioning member 3 and push the front substrate positioning member 3 forward to drive the sliding rod 34 to slide forward together to compress the positioning spring 35, and then Figure 5 , put the LED ceramic substrate 8 between the two substrate positioning members 3 of the front and rear substrate positioning units 31 and 32, so that the right edge 803 of the LED ceramic substrate 8 is close to the second guide surface 302 of the two substrate positioning members 3 (see Figure 8 ) on. See Figure 5 、 Figure 6 Release the front substrate positioning member 3 and allow the positioning spring 35 to slide the front substrate positioning member 3 backward until the two substrate positioning members 3 rest on the front right corner 81 and rear right corner 82 of the LED ceramic substrate 8, respectively, and together laterally clamp the LED ceramic substrate 8. The front substrate positioning member 3 laterally limits the LED ceramic substrate 8 in the front and right directions, thereby achieving lateral positioning of the LED ceramic substrate 8. The rear substrate positioning member 3 laterally limits the LED ceramic substrate 8 in the rear and right directions, thereby achieving lateral positioning of the LED ceramic substrate 8.
[0031] See Figure 3 and Figure 5 After the LED ceramic substrate 8 is positioned, press down the LED ceramic substrate 8 to make it stick to the sticking surface 911 of the middle effective part 91 of the adhesive tape 9, and then Figure 7As shown, the cutter 2 is operated to cut away the excess portions 92 and 93 of the tape 9. As the cutter 2 cuts, the two blades 22 pass horizontally across the front and rear edges 801 and 802 of the LED ceramic substrate 8, respectively. If the two substrate retaining members 3 rest against the front right corner 81 and rear right corner 82 of the LED ceramic substrate 8, they will block the cutter 2. To ensure that the cutter 2 can successfully remove the excess portions 92 and 93 of the tape 9, the two substrate retaining members 3 should be propped apart with an object before operating the cutter 2. This will allow the front retaining member 3 to move forward and the rear retaining member 3 to move backward. This will prevent the two retaining members 3 from blocking the cutter 2.
[0032] See Figure 3 In this embodiment, the tape roll support cylinder 51 and the pressure roller 52 both serve as tape guides, located at the beginning 101 of the tape placement platform 1, guiding the free end 905 of the tape roll 90 toward the end 102 of the tape placement platform 1, allowing a person to manually pull the free end 905 of the tape roll 90 forward and then spread the longitudinal tape 9 flatly onto the tape placement platform 1 for attachment to the LED ceramic substrate 8. In other embodiments, other tape guides may be used instead, such as providing two lateral guide plates at the beginning of the tape placement platform, with the spacing between the two lateral guide plates being narrower in front and wider in the back. The two lateral guide plates guide the free end of the tape roll toward the end of the tape placement platform to prevent it from deviating, allowing a person to manually pull the free end of the tape roll forward and then spread the longitudinal tape flatly onto the tape placement platform 1 for attachment to the LED ceramic substrate 8.
[0033] See Figure 3 In this embodiment, since the longitudinal tape 9 is pulled out from the tape roll 90, the excess portion 93 at the rear end is cut off and used as the new free end 93 of the tape roll 90, and no cleaning is required, so the pressing plate 6 is as shown in FIG. Figure 4 , only pressing the redundant portion 92 at the front end of the longitudinal tape 9 without pressing the redundant portion 93 at the rear end of the longitudinal tape 9. Figure 3 、 Figure 4 The operator first cuts out a section of longitudinal tape 9 and then spreads it flat on the tape placement table 1. After cutting, the excess parts 92 and 93 at the front and rear ends of the longitudinal tape 9 need to be cleaned, so the pressing plate 6 is correspondingly changed to press the adhesive surface of the excess parts 92 and 93 at the front and rear ends of the longitudinal tape 9 at the same time. After cutting, the pressing plate 6 is lifted to take away the excess parts 92 and 93 at the front and rear ends of the longitudinal tape 9.
[0034] The above is only an embodiment of the present invention and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the present invention and still fall within the scope of patent protection.
