[0030] See also Figure 1 , Figure 2 and Figure 3 In one embodiment of the present application, an attaching mechanism 100 is provided for attaching an adhesive tape to a first connecting block and a second connecting block which are vertically connected to each other, so the adhesive tape is L-shaped, and the adhesive tape includes a first adhesive portion and a second adhesive portion, the first adhesive portion and the second adhesive portion are vertically connected to each other, the first adhesive portion is used to attach to the first connecting block, and the second adhesive portion is used to attach to the second connecting block. In order to improve the attaching accuracy, it is necessary to ensure that the right angle formed by the first adhesive portion and the second adhesive portion coincides with the right angle formed by the first connecting block and the second connecting block, that is, the first adhesive portion and the first connecting block have the same extension direction, and the second adhesive portion and the second connecting block have the same extension direction. The attaching device 10 includes an attaching mechanism 100, a driving mechanism 200 and a fine-tuning mechanism 300, the attaching mechanism 100 is connected to the driving mechanism 200, and the fine-tuning mechanism 300 is connected to the attaching mechanism 100.
[0031] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the attachment mechanism 100 includes a mounting plate 130, a first attachment 110, and a second attachment 120. The mounting plate 130 has a first surface 131 and a second surface 132 in the thickness direction thereof. Obviously, the first surface 131 and the second surface 132 are oriented in opposite directions. Both the first attachment 110 and the second attachment 120 are arranged on the first surface 131. The first attachment 110 is used to absorb the first adhesive portion and attach the first adhesive portion to the first connecting block, and the second attachment 120 is used to absorb the second adhesive portion and attach the second adhesive portion to the second connecting block. The first attachment 110 and the second attachment 120 are both provided with a vacuum hole 111. When a vacuum generator is used to evacuate the vacuum hole 111, a vacuum will be generated in the vacuum hole 111, so that the first adhesive portion is adsorbed on the first attachment 110 and the second adhesive portion is adsorbed on the second attachment 120. With reference to the first direction, the second direction and the third direction which are mutually perpendicular, the first attachment 110 and the first connecting block extend in the first direction, and the second attachment 120 and the second connecting block extend in the second direction. The first direction may be the X-axis direction, the second direction may be the Y-axis direction, and the third direction may be the Z-axis direction. The first attachment 110 may be fixedly connected to the mounting plate 130, and the second attachment 120 may be rotatably connected to the mounting plate 130. In the actual working process, the first attachment 110 adsorbed with the first adhesive portion may be first aligned with the first connecting block, that is, the first attachment 110 is located directly above the first connecting block and extends in the first direction, and then the second attachment 120 adsorbed with the second adhesive portion may be rotated relative to the mounting plate 130 by a certain angle to ensure that the rotated second attachment 120 is aligned with the second connecting block, that is, the second attachment 120 is located directly above the second connecting block and extends in the second direction. Therefore, after the first attachment 110 extends in the first direction, the second attachment 120 can be rotated by a certain angle to extend in the second direction, ultimately ensuring that the right angle formed by the first attachment 110 and the second attachment 120 coincides with the right angle formed by the first connecting block and the second connecting block.
[0032] See also Figure 3 , Figure 4 and Figure 5In some embodiments, there is a clearance gap 140 between the ends of the first attachment 110 and the second attachment 120 that are close to each other. By providing the clearance gap 140, the first attachment 110 can be prevented from interfering with the second attachment 120 during its rotation, ensuring smooth rotation of the second attachment 120. The second attachment 120 can rotate relative to the mounting plate 130 around the second rotation axis 12 extending along the third direction. The second rotation axis 12 is spaced apart from the first rotation axis 11 and is parallel to each other. The second rotation axis 12 is arranged close to the clearance gap 140.
[0033] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the driving mechanism 200 includes a driving assembly 210 and a driving motor 220. The driving motor 220 is disposed on the driving assembly 210. The driving shaft of the driving motor 220 extends along the third direction, so that the driving shaft of the driving motor 220 is connected to the second surface 132 of the mounting plate 130. In this way, the driving motor 220 is located on one side of the mounting plate 130 in the thickness direction, that is, on the side where the second surface 132 is located, and the first attachment 110 and the second attachment 120 are located on the other side of the mounting plate 130 in the thickness direction, that is, on the side where the first surface 131 is located. When the driving shaft of the driving motor 220 rotates around the first rotating shaft 11 extending in the third direction, the driving shaft of the driving motor 220 will drive the mounting plate 130 and the entire attachment mechanism 100 to rotate around the first rotating shaft 11 extending in the third direction. Therefore, the driving shaft of the driving motor 220 can first drive the mounting plate 130 to rotate, so that the first attachment 110 extends along the first direction to be located directly above the first connecting block.
[0034] See also Figure 1 , Figure 2 and Figure 3The driving assembly 210 includes a body 211, a driver 212 and a sliding member 213. The sliding member 213 is slidably connected to the body 211 along the third direction. The driver 212 is disposed on the body 211 and connected to the sliding member 213. The driver 212 can drive the sliding member 213 to slide back and forth along the third direction. The driving motor 220 is disposed on the sliding member 213. Therefore, when the driver 212 drives the sliding member 213 to perform reciprocating linear motion in the third direction, the driving motor 220, the attaching mechanism 100 and the fine-tuning assembly 330 will produce synchronous motion with the sliding member 213, and then the attaching mechanism 100 moves toward or away from the first connecting block and the second connecting block along the third direction. For example, when the first adhesive portion and the second adhesive portion need to be attached, the attaching mechanism 100 can be moved toward the first connecting block and the second connecting block until the first attaching attachment 110 contacts the first connecting block and the second attaching attachment 120 contacts the second connecting block. After the attachment is completed, the attachment mechanism 100 can be moved away from the first connection block and the second connection block. The driver 212 can be a screw rod 332 or a cylinder, etc., as long as the driver 212 can drive the sliding member 213 to move linearly.
[0035] See also Figure 3 , Figure 4 and Figure 5 In some embodiments, the fine-tuning mechanism 300 includes an arc-shaped guide rail 310, a slider 320 and a fine-tuning assembly 330. The arc-shaped guide rail 310 is fixedly connected to the mounting plate 130. The arc-shaped guide rail 310 can be fixed on the second surface 132. The center of the circle where the arc-shaped guide rail 310 is located is located at the second rotating shaft 12. In layman's terms, the arc-shaped guide rail 310 is arranged around the second rotating shaft 12. The slider 320 is fixedly connected to an end of the second attachment 120 away from the first attachment 110, and the slider 320 and the arc-shaped guide rail 310 are slidably matched. The fine-tuning assembly 330 is arranged on the mounting plate 130 and is used to drive the slider 320 to move. The fine-tuning assembly 330 is located on the side where the second surface 132 of the mounting plate 130 is located. It can be understood that the fine-tuning assembly 330 and the first attachment 110 and the second attachment 120 are located on opposite sides of the mounting plate 130 in the thickness direction. When the fine-tuning assembly 330 drives the slider 320 to slide along the arc guide rail 310, the slider 320 will rotate around the second rotation axis 12, and then the second attachment 120 will follow the sliding member 213 to rotate around the second rotation axis 12, and finally the second attachment 120 will extend along the second direction to be located directly above the second connecting block.
[0036] See also Figure 3 , Figure 4 and Figure 5The fine-tuning assembly 330 includes a fine-tuning motor 331 and a screw rod 332. The fine-tuning motor 331 is disposed on the second surface 132 of the mounting plate 130 and connected to the screw rod 332. The screw rod 332 is disposed in the slider 320 and is rotatably connected to the slider 320 and the mounting plate 130. When the fine-tuning motor 331 drives the screw rod 332 to rotate, the screw rod 332 drives the slider 320 to slide along the arc guide rail 310, and then the slider 320 drives the second attachment 120 to rotate around the second rotation axis 12. Of course, the fine-tuning assembly 330 can also use a cylinder, etc., as long as it can drive the slider 320 to slide along the arc guide rail 310.
[0037] See also Figure 2 , Figure 3 and Figure 4 The working principle of the attaching device 10 is described below:
[0038] In the first step, the vacuum hole 111 generates a vacuum, and then the first adhesive part is adsorbed on the first attachment 110, and the second adhesive part is attached to the second attachment 120. Then the driver 212 drives the sliding member 213 to move close to the first connecting block and the second connecting block, and then the attaching mechanism 100 moves close to the first connecting block and the second connecting block.
[0039] In the second step, the driving motor 220 drives the mounting plate 130 and the entire attaching mechanism 100 to rotate around the first rotating shaft 11, so that the first attaching attachment 110 is located directly above the first connecting block, that is, the first attaching attachment 110 extends along the first direction. Of course, the orthographic projection of the first attaching attachment 110 along the third direction can all fall on the first connecting block.
[0040] In the third step, the fine-tuning motor 331 drives the lead screw 332 to rotate, and then the slider 320 slides along the arc guide rail 310. The slider 320 drives the second attachment 120 to rotate around the second rotation axis 12, and finally the second attachment 120 is located directly above the second connecting block, that is, the second attachment 120 extends along the second direction. Of course, the orthographic projection of the second attachment 120 along the third direction can all fall on the second connecting block.
[0041] In the fourth step, the driver 212 drives the sliding member 213 to move closer to the first connection block and the second connection block, and then the first attachment 110 contacts the first connection block, thereby attaching the first adhesive portion to the first connection block, and the second attachment 120 contacts the second connection block, thereby attaching the second adhesive portion to the second connection block. After the first adhesive portion and the second adhesive portion are attached, the driver 212 can drive the sliding member 213 and the entire attachment mechanism 100 to move away from the first connection block and the second connection block.
[0042] Therefore, first, the mounting plate 130 is driven to rotate around the first rotating shaft 11 by the driving motor 220, so that the first attachment 110 is aligned with the first connecting block, that is, the first attachment 110 is accurately positioned; then, the second attachment 120 is driven to rotate around the second rotating shaft 12 by the fine-tuning motor 331, so that the second attachment 120 is aligned with the second connecting block, that is, the second attachment 120 is accurately positioned, thereby improving the positioning accuracy of both the first attachment 110 and the second attachment 120, thereby improving the attachment accuracy of the entire attaching device 10 for the tape.
[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
