The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] The terms "first", "second", "third", and the like as used herein are only for descriptive purposes and not to be construed as indicating or implying relative importance.

[0035] An embodiment of the present application provides a material pasting device for pasting a material piece to a product. The material pasting device comprises a moving base, a rotating assembly, a material pasting fixing member, a rotating driving member and a pressure maintaining driving assembly. The rotating assembly is rotationally connected with the moving base. The material pasting fixing member is connected with the rotating assembly and is configured to fix the material piece.

The pressure maintaining driving assembly is connected with the moving base and is configured to drive the moving base to move in a first direction, so that the material piece is close to the product and is pasted to the product.

[0036] When pasting the material piece to the product, the material piece can be first placed on the material pasting fixing member, the material pasting fixing member is used to fix the material piece, then the rotating assembly is rotated, so that the material piece is aligned with a pasting position of the material piece to be pasted on the product, then the pressure maintaining driving member is used to drive the moving base to move, so that the material piece is in contact with and pasted to a pasting area of the material piece to be pasted on the product, thereby completing the pasting operation of the material piece. The material pasting device can keep the material piece aligned with the position of the material piece to be pasted on the product when pasting the material piece, thereby improving the pasting precision of the material piece.

[0037] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0038] Reference Figure 1 An embodiment of the present application provides a material pasting device 1000, which comprises a moving base 100, a rotating assembly 200, a material pasting fixing member 300, a rotating driving member 400, a pressure maintaining driving assembly 500 and a base 600. The rotating assembly 200 is rotationally connected with the moving base 100. The material pasting fixing member 300 is connected with the rotating assembly 200. The rotating driving member 400 is arranged on the moving base 100. The pressure maintaining driving assembly 500 is arranged on the base 600 and is connected with the moving base 100. The material pasting fixing member 300 is configured to fix the material piece. The rotating driving member 400 is configured to drive the rotating assembly 200 to rotate. The pressure maintaining driving assembly 500 is configured to drive the moving base 100 to move in a first direction Z. Exemplarily, the base 600 is in a plate shape. The first direction Z is parallel to the thickness direction of the base 600.

[0039] After the material piece is placed on the material fixing member 300 and the material fixing member 300 is fixed, the rotating driving member 400 drives the rotating assembly 200 to rotate, so that the material piece is aligned with the material piece to be attached on the product, and then the pressure maintaining driving member 53 drives the moving seat 100 to move, so that the material piece moves towards the product and contacts and attaches with the material piece to be attached on the product, thereby completing the attachment of the material piece. For example, the first direction Z is parallel to the vertical direction, when the moving seat 100 drives the material fixing member 300 with the material piece to move downwards along the first direction Z, the material piece approaches the position of the material piece to be attached on the product.

[0040] With reference to Figure 1 and Figure 2 In some embodiments, the base 600 is provided with a matching part 61, and the moving seat 100 is provided with a sliding part 11, which is matched with the matching part 61 along the first direction Z. For example, the matching part 61 is a sliding rail, and the sliding part 11 is a sliding seat. In other embodiments, the matching part 61 can be a guide rod, and the sliding part 11 can be a sliding sleeve. The sliding part 11 matched with the matching part 61 can improve the stability of the moving seat 100 moving along the first direction Z, thereby improving the accuracy of the material piece aligned with the position of the material piece to be attached on the product.

[0041] With reference to Figure 2 and Figure 3 In some embodiments, the rotating assembly 200 includes a rotating seat 21, a rotating seat 22 and a rotating member 23. The rotating seat 21 is provided with a first rotating shaft 211, which is rotationally connected with the moving seat 100; the rotating seat 22 is provided with a second rotating shaft 221, which is rotationally connected with the rotating seat 21, and it can be understood that the material fixing member 300 is connected with the rotating seat 22. For example, the rotating driving member 400 is a motor, which is connected with the first rotating shaft 211 through a transmission structure, so as to drive the rotating seat 21 to rotate; the rotating member 23 is a rotary cylinder, and the rotating shaft of the rotary cylinder is connected with the second rotating shaft 221, so as to drive the rotating seat 22 to rotate. In other embodiments, the rotating driving member 400 can also be a rotary cylinder or other structure capable of driving the rotating seat 21 to rotate. In other embodiments, the rotating member 23 can also be a motor or other structure capable of driving the rotating seat 22 to rotate.

[0042] The axial direction of the first rotating shaft 211 is defined as the second direction X, the axial direction of the second rotating shaft 221 is parallel to the second direction X, and the second rotating shaft 221 is spaced apart from the first rotating shaft 211 along the third direction Y, which is perpendicular to the second direction X. In some embodiments, the second direction X can intersect the first direction Z, and exemplarily, the second direction X is perpendicular to the first direction Z. In other embodiments, the second direction X can be parallel to the first direction Z. The third direction Y shown in the figure is the direction of the rotating assembly 200 in the initial state, and it can be understood that the third direction Y changes as the rotating seat 21 rotates, but the third direction Y always remains perpendicular to the second direction X.

[0043] Through the two rotations of the rotating seat 21 and the rotating seat 22, the movement range of the material piece can be increased, so as to facilitate the material piece or the material fixing piece 300 to bypass part of the structure on the product, thereby reducing the possibility of interference and the like, and thus the application range of the material pasting device 1000 can be improved.

[0044] Referring to Figure 3 and Figure 4 In some embodiments, the material fixing piece 300 includes a material pressing head 31, and the material pressing head 31 is connected with the rotating seat 22. In some embodiments, the material pressing head 31 is integrally formed with the rotating seat 22. Figure 3 The dashed line at the material pressing head 31 is used to separate the material pressing head 31 and the rotating seat 22, and in other embodiments, the dashed line used to separate the material pressing head 31 and the rotating seat 22 can be of other shapes or located at other positions.

[0045] The material pressing head 31 is provided with a vacuum suction nozzle 311, and the inside of the material pressing head 31 is provided with an air channel (not shown in the figure), the vacuum suction nozzle 311 is communicated with the air channel, and the air channel is connected with a negative pressure source. After the material piece is placed on the vacuum suction nozzle 311, the negative pressure source can form a vacuum inside the air channel, so that a vacuum is formed inside the vacuum suction nozzle 311, thereby enabling the vacuum suction nozzle 311 to adsorb the material piece to fix the material piece; after the material piece is completed, the negative pressure source is disconnected, so that the material piece is separated from the vacuum suction nozzle 311.

[0046] In some embodiments, the vacuum suction nozzle 311 is provided with an adsorption surface 3111, and the adsorption surface 3111 is shaped according to the surface of the material piece to be adsorbed. By shaping the adsorption surface 3111 according to the surface of the material piece, the adsorption surface 3111 can be fully attached to the material piece, thereby improving the stability of the vacuum suction nozzle 311 in adsorbing the material piece.

[0047] In some embodiments, the vacuum nozzle 311 is further provided with a plurality of positioning protrusions 3112, which are arranged around the adsorption surface 3111. Two positioning protrusions 3112 can respectively abut against two adjacent sidewalls of the workpiece, thereby achieving a positioning effect on the workpiece. This helps to improve the positional accuracy of the workpiece adsorbed on the vacuum nozzle 311, and further improves the mounting accuracy of the workpiece. For example, the number of positioning protrusions 3112 is two.

[0048] In some embodiments, the material attaching fastener 300 can be a clamping mechanism; for example, the material attaching fastener 300 is a pneumatic gripper. In other embodiments, the material of the material is ferromagnetic, and the corresponding material attaching fastener 300 can also be an electromagnet.

[0049] Reference Figure 5 and Figure 6 In some embodiments, the pressure-holding drive assembly 500 includes a connector 51, a pressure-holding member 52, and a pressure-holding drive member 53. The connector 51 is connected to the movable base 100 (see...). Figure 1 The pressure-holding member 52 is connected to the base 600, and the connecting member 51 is inserted into the connecting part 521. The pressure-holding drive member 53 is connected to the pressure-holding member 52 and configured to drive the pressure-holding member 52 to move along the first direction Z. In some embodiments, the pressure-holding drive member 53 is a cylinder, the cylinder body of the pressure-holding drive member 53 is connected to the base 600, and the piston rod of the pressure-holding drive member 53 is connected to the pressure-holding member 52. In other embodiments, the pressure-holding drive member 53 may be a linear motor or other structural member capable of driving the pressure-holding member 52 to move along the first direction Z.

[0050] In some embodiments, the connecting portion 521 is orifice-shaped, and the pressure-holding member 52 is generally U-shaped. The connecting member 51 includes a first rod 511 and a second rod 512, which are interconnected and generally form an integral L-shaped structure; the first rod 511 is fixedly connected to the movable seat 100, and the second rod 512 is inserted into the connecting portion 521. When the pressure-holding drive member 53 drives the pressure-holding member 52 to move along the first direction Z, the inner wall of the connecting portion 521 abuts against the second rod 512, causing the movable seat 100 to move along the first direction Z with the second rod 512. In other embodiments, the first rod 511 may be omitted, and the second rod 512 may be fixedly connected to the movable seat 100.

[0051] In some embodiments, a space is provided between the connecting portion 521 and the connecting piece 51 for the second rod 512 to move relative to the connecting portion 521 along the first direction Z. It can be understood that the size of the connecting portion 521 along the first direction Z is greater than the size of the second rod 512 along the first direction Z. In some embodiments, the pressure maintaining piece 52 is provided with a connecting hole 522 penetrating through the connecting portion 521 along the first direction Z. The pressure maintaining driving assembly 500 further comprises a buffer piece 54 provided between the pressure maintaining piece 52 and the connecting piece 51. In some embodiments, the buffer piece 54 is an elastic piece 541, which is a spring. The elastic piece 541 is inserted into the connecting hole 522 and abuts against the connecting piece 51. The inner wall of the connecting hole 522 is threadedly connected with an adjusting stud 5221. The adjusting stud 5221 is located on the side of the elastic piece 541 away from the second rod 512 along the first direction Z, and the end of the elastic piece 541 away from the second rod 512 along the first direction Z abuts against the adjusting stud 5221. In some embodiments, the second rod 512 is provided with a receiving hole 5122, and the end of the elastic piece 541 close to the second rod 512 is inserted into the receiving hole 5122. The receiving hole 5122 limits the elastic piece 541, which can improve the stability of the abutment between the elastic piece 541 and the second rod 512.

[0052] In other embodiments, the elastic piece 541 can be a rubber pad or other elastic structure.

[0053] During the movement of the pressure maintaining piece 52 driven by the pressure maintaining driving piece 53 to move the material piece towards the product, the elastic piece 541 is compressed and deformed when the pressure maintaining piece 52 moves relative to the second rod 512 along the first direction Z, so that the elastic piece 541 has a buffering effect on the pressure maintaining piece 52. At the same time, the elastic piece 541 has an elastic force on the second rod 512, so that the moving seat 100 generates a force on the material piece through the material-attaching pressure head 31, thereby attaching the material piece to the product. Taking the case where the first direction Z is parallel to the vertical direction as an example, it can be understood that the connecting hole 522 is located above the second rod 512, and the elastic piece 541 abuts against the upper surface of the second rod 512.

[0054] In some embodiments, by rotating the adjusting stud 5221, the deformation amount of the elastic piece 541 in the initial state can be adjusted, so that the size of the elastic force generated by the elastic piece 541 when a unit length of the elastic piece 541 is compressed and deformed can be adjusted according to different products or material pieces, so as to reduce the risk of damage to the material piece or the product due to excessive force during the attaching process.

[0055] In some embodiments, the buffer 54 can also be a structure that buffers the pressure-keeping member 52 by friction, for example, the buffer 54 is in the shape of a block connected to the connecting member 51, the buffer 54 is provided with a buffer hole, the pressure-keeping member 52 is inserted into the buffer hole, and the inner circumferential wall of the buffer hole is in contact with the outer circumferential wall of the pressure-keeping member 52; when the pressure-keeping member 52 moves relative to the connecting member 51, the pressure-keeping member 52 is slowed down and buffered by the friction between the inner wall of the buffer hole and the outer wall of the pressure-keeping member 52, so as to reduce the probability of impact between the pressure-keeping member 52 and the connecting member 51, thereby reducing the risk of damage to the product or the material.

[0056] In some embodiments, the base 600 (see Figure 1 ) is provided with a stop portion 62, and the moving seat 100 (see Figure 1 ) is provided with a limiting portion 12, the stop portion 62 is configured to stop the limiting portion 12 in the first direction Z when the material moves towards the product. In some embodiments, the limiting portion 12 is provided on the second rod 512. The stop portion 62 can stop the limiting portion 12 to limit the extreme position of the moving seat 100 when driving the material to move towards the product, thereby reducing the risk of damage to the product or the material caused by excessive force when the material contacts the product.

[0057] In some embodiments, the stop portion 62 and the limiting portion 12 are provided with two groups, one group of the stop portion 62 and the limiting portion 12 cooperate to limit the extreme position of the moving seat 100 when driving the material to move towards the product, and the other group of the stop portion 62 and the limiting portion 12 cooperate to limit the extreme position of the moving seat 100 when driving the material pressing head 31 to move away from the product. In some embodiments, the limiting portion 12 can be provided on the base 600, and the corresponding stop portion 62 can be provided on the second rod 512 or the moving seat 100.

[0058] In some embodiments, the second rod 512 is provided with an adjusting screw hole 5121 in the first direction Z, and the limiting portion 12 is a screw, and the limiting portion 12 is threadedly connected with the adjusting screw hole 5121. By rotating the limiting portion 12, the position of the limiting portion 12 relative to the second rod 512 in the first direction Z can be adjusted, so as to adjust the position of the limiting portion 12 relative to the movement in the first direction Z. By adjusting the position of the limiting portion 12 relative to the moving seat 100, the extreme position of the moving seat 100 when driving the material to move towards the product can be adjusted according to different products or materials. In other embodiments, the limiting portion 12 can also be fixed relative to the second rod 512 by screwing or by means of a latch, so as to facilitate the adjustment of the position of the limiting portion 12 relative to the second rod 512 in the first direction Z.
