[0049] The wiping mechanism 6 is located on one side of the Y-axis dispensing mechanism 3, and the rotating end of the rotating mechanism 5 is connected with a rotating arm, which extends along the moving direction of the X-axis dispensing mechanism, so that the clamping part 51 can extend to the wiping mechanism during rotation, and the wiping mechanism wipes the product on the clamping part 51 to remove the excess shielding glue in the non-shielding area of the product, ensuring the integrity of the product and not affecting the subsequent processing.

[0050] The dispensing head 41 is connected with a heating piezoelectric spray valve, and continuous operation can ensure the consistency of dispensing.

[0051] In some embodiments, as shown in Figure 1 The moving end of the Z-axis dispensing mechanism 4 is also provided with an identification mechanism 7, and the identification end faces the base 11, and the identification mechanism 7 is used to identify the dispensing condition of the shielding glue on the product and the completeness of the wiping, so the identification end faces the base 11, which is consistent with the dispensing direction of the dispensing head 41, and the dispensing head 41 is dispensing continuously, while the identification mechanism 7 synchronously identifies whether there is an error or omission in the dispensing of the shielding glue.

[0052] Further, as shown in Figure 2 The identification mechanism 7 includes a first CCD identification part 71 and an AOI detection part 72, and the first CCD identification part 71 and the AOI detection part 72 are respectively located on both sides of the dispensing head 41.

[0053] The appearance of the product is detected through the display and the controller by the first CCD identification part 71, and the CCD adopts a silicon-based semiconductor processing technology, and the electric field generated by the electrode promotes the transmission of the charge link to the central analog-to-digital converter in the controller, and the high-resolution first CCD identification part 71 can accurately identify the mark point of the product and the dispensing trajectory of the shielding glue, ensuring the dispensing precision and quality, and adjusting adaptively according to the tolerance of the product itself, ensuring the dispensing quality and also detecting the glue type after dispensing.

[0055] The first CCD identification part 71 and the AOI detection part 72 can move up and down synchronously with the moving end of the Z-axis dispensing mechanism 4, and move horizontally synchronously with the moving end of the X-axis dispensing mechanism 2, and match the synchronous Y-axis dispensing mechanism 3 and the rotating mechanism 5 to rotate the product, so that the product can be identified and detected in all directions during dispensing, preventing dispensing errors, omissions, etc., and improving accuracy and stability.

[0056] In some embodiments, referring to Figure 2 As shown, the moving end of the Z-axis dispensing mechanism 4 is further provided with a UV curing lamp 8, which can follow the moving end of the Z-axis dispensing mechanism 4 to move up and down in the vertical direction, and synchronously move up and down with the dispensing head 41. After the dispensing head 41 dispenses glue on the product, the UV curing lamp 8 is synchronously turned on to cure the part of the product on which the dispensing is just completed, so as to achieve the effect of reducing glue flow and improving dispensing precision by dispensing and curing simultaneously.

[0057] In some embodiments, referring to Figure 3 As shown, the glue wiping mechanism 6 includes a connecting seat 61, a guide wheel 62, a first pivoting wheel 63, a first driving member 64, and a wiping belt 65. The connecting seat 61 is provided with a connecting plate 611, the first driving member 64 is installed on the connecting seat 61 and the driving end penetrates through the connecting plate 611, the bottom of the connecting seat 61 is provided with a supporting leg, the connecting seat 61 is lifted to a certain height by the supporting leg to ensure that the product can be close enough, the connecting plate 611 is installed on the connecting seat 61 in the vertical direction, and the connecting plate 611 separates the rotating mechanism 5 to avoid the rotating mechanism 5 or the dispensing head 41 affecting the first driving member 64.

[0058] The first driving member 64 can adopt a driving motor, and a pivoting opening or a pivoting bearing can be formed on the connecting plate 611, so that the driving end of the driving motor can extend to the rotating mechanism 5 through the connecting plate 611.

[0059] The first pivoting wheel 63 is connected with the driving end of the first driving member 64, a rubber layer can be provided on the surface of the first pivoting wheel 63 to improve the friction, and the first pivoting wheel 63 can rotate with the driving end of the first driving member 64.

[0060] The guide wheel 62 is installed on the connecting plate 611, and the guide wheel 62 can guide the wiping belt 65. The wiping belt 65 is sleeved on the first pivoting wheel 63 and the guide wheel 62. The first pivoting wheel 63 is driven by the first driving member 64 to rotate the wiping belt 65 along the first pivoting wheel 63 and the guide wheel 62. During the rotation, the place of the product to be wiped contacts the wiping belt 65, so that the shielding glue outside the dispensing range of the shielding glue on the product can be wiped off.

[0061] The wiping belt 65 can adopt a dust-free cloth, and the front and back surfaces of the dust-free cloth can be used.

[0062] The first pivoting wheel 63 is provided with an annular groove, and the wiping belt 65 is located in the annular groove to be limited, so as to avoid the wiping belt 65 from separating from the first pivoting wheel 63.

[0063] Specifically, the product moves to the wiping belt 65 along with the rotating mechanism 5 and the clamping member 51. The wiping belt 65 is located between any guide wheel 62 and the first pivot wheel 63. As the first driving member 64 drives the first pivot wheel 63 to rotate, the wiping belt 65 rotates between the first pivot wheel 63 and the guide wheel 62. During the rotation, the wiping belt 65 contacts the product surface, thereby wiping the masking adhesive on the product surface that is outside the dispensing range of the masking adhesive.

[0064] In another embodiment, reference Figure 4 As shown, the adhesive application mechanism 6 also includes a second pivot wheel 66 and a second drive member 67; the second drive member 67 is mounted on the connecting base 61, and the drive end passes through the connecting plate 611. The second pivot wheel 66 is connected to the drive end of the second drive member 67. The second drive member 67 is the same as the first drive member 64, and both can be driven by a motor. The second pivot wheel 66 is the same style as the first pivot wheel 63, and the size can be adjusted, which will not be described in detail here.

[0065] One end of the wiping belt 65 is connected to the first pivot wheel 63, and the other end passes around several guide wheels 62 and is connected to the second pivot wheel 66. The wiping belt 65 is wrapped around the first pivot wheel 63 or the second pivot wheel 66. The length of the wiping belt 65 can be set to be very long, so that both the first pivot wheel 63 and the second pivot wheel 66 can wrap the wiping belt 65. This method can increase the service life of the wiping belt 65 and reduce the need for replacement.

[0066] Specifically, when the first driving member 64 drives the first pivot wheel 63 to rotate, the wiping belt 65 wraps around the first pivot wheel 63, while the other end unwinds from the second pivot wheel 66. The second driving member 67 can simultaneously drive the second pivot wheel 66 to rotate, so that the wiping belt 65 can be stably wrapped around the first pivot wheel 63. During the wrapping process, the product can come into contact with the wiping belt 65 to wipe away residual adhesive dots. Conversely, the second driving member 67 drives the second pivot wheel 66 to rotate in the opposite direction, so that the wiping belt 65 gradually unwinds from the first pivot wheel 63 and wraps around the second pivot wheel 66, thereby increasing the loadable length of the wiping belt 65 and improving its service life.

[0067] When the first driving component 64 rotates, the second driving component 67 can rotate synchronously, and vice versa, in order to avoid insufficient tension when in contact with the product. The rotation speed is limited by any driving component to ensure the stability of the tension.

[0068] Further reference Figure 4 As shown, the adhesive wiping mechanism 6 also includes a tensioning member 68, which is installed on the connecting plate 611 and abuts against the wiping belt 65. The tensioning member 68 can be an elastic tensioning plate or an electric tensioning push rod. The tensioning member can abut against a part of the wiping belt 65, so that the tension of the wiping belt 65 is stabilized.

[0069] Further, referring to Figure 4 As shown, the tensioning member 68 is further connected with a cleaning member 69, the tensioning member 68 can adopt a tensioning electric push rod, the electric push rod is installed on the connecting plate 611 in the vertical direction, and the extension end is in contact with the wiping belt 65, at the same time, the cleaning member 69 is installed on the extension end of the electric push rod, the cleaning member 69 can adopt a nozzle, the nozzle is connected with a conveying hose, the conveying hose is connected with an external liquid storage cylinder, and is used for conveying cleaning liquid, the cleaning liquid can be IPA or other cleaning chemicals, which is not limited here, and the IPA is isopropyl alcohol, which provides cleaning for the wiping belt 65.

[0070] When the tensioning member 68 abuts against the wiping belt 65, the nozzle can spray the cleaning liquid such as IPA towards the wiping belt 65, and cooperate with the friction between the wiping belt 65 and the tensioning member 68, so that the cleaning liquid can be stably attached to the wiping belt 65, to clean the residual glue points wiped off by the wiping belt 65, and further improve the service life of the wiping belt 65.

[0071] In some embodiments, referring to Figure 5 As shown, the base 11 is further provided with a guide rail 111; the guide rail 111 is provided with a sliding block 112, and the identification mechanism 7 further includes a second CCD identification member 73 connected to the top of the sliding block 112, the installation direction of the guide rail 111 is consistent with the installation direction of the Y-axis dispensing structure, the sliding block 112 can slide along the guide rail 111, and the second CCD identification member 73 has the same structure as the first CCD identification member 71, and can provide image recognition detection, the second CCD identification member 73 can change the identification position by moving the sliding block 112 along the guide rail 111, so that each position of the product can be identified, and the fullness and integrity of the product dispensing and wiping are further ensured.

[0072] The first pivot wheel 63 is connected with a first winding wheel 631 away from the connecting plate 611, the second pivot wheel 66 is connected with a second winding wheel 661 away from the connecting plate 611, the first winding wheel 631 is connected with a first linkage rope 632, one end of the first linkage rope 632 is wound around the first winding wheel 631, and the other end is connected with one end of the sliding block 112, the first pivot wheel 63 can drive the first winding wheel 631 to rotate synchronously when the first pivot wheel 63 rotates, the first winding wheel 631 can release or wind the first linkage rope 632, and the first linkage rope 632 can pull the sliding block 112 to move along the guide rail 111 towards the first pivot wheel 63 when winding.

[0073] The second winding wheel 661 is connected with a second linkage rope 662, one end of the second linkage rope 662 is wound on the second winding wheel 661, and the other end is connected with the other end of the sliding block 112. When the second pivot wheel 66 rotates, the second winding wheel 661 can be synchronously driven to rotate, and the rotation of the second winding wheel 661 can release or wind the second linkage rope 662. When winding, the second linkage rope 662 can pull the sliding block 112 to move along the guide rail 111 to the direction of the second pivot wheel 66.

[0074] Therefore, when the first winding wheel 631 rotates with the first pivot wheel 63, the first linkage rope 632 is wound, and the sliding block 112 is synchronously driven to move to the direction of the first winding wheel 631. The second winding wheel 661 synchronously releases the second linkage rope 662. Conversely, when the second winding wheel 661 rotates in the opposite direction with the second pivot wheel 66, the second linkage rope 662 is wound, the second linkage rope 662 pulls the sliding block 112 to move along the guide rail 111 to the direction of the second winding wheel. The movement of the sliding block 112 changes the identification position of the second CCD identification piece 73, so that the second CCD identification piece 73 can identify the product through different positions.

[0075] Further, the connection mode of the second CCD identification piece 73 and the sliding block 112 is hinged, that is, a hinge frame can be arranged between the second CCD identification piece 73 and the sliding block 112 for connection. The second CCD identification piece 73 can adjust the identification angle along the hinge point to ensure that the product is provided with omnidirectional CCD identification.

[0076] The top of the sliding block 112 is also provided with a V-shaped limiting block 113. When the second CCD identification piece 73 is inclined along the hinge point, it abuts against any side of the limiting block 113. The V-shaped limiting block 113 can make the second CCD identification piece 73 be able to abut against any side of the V-shaped limiting block 113 when it is inclined to any side along the hinge point, thereby limiting the second CCD identification piece 73 and avoiding the second CCD identification piece 73 from continuing to incline to one side.

[0077] Reference Figure 5 As shown in the figure, the base 11 at both ends of the guide rail 111 is also provided with oppositely arranged pushing parts 13. When the sliding block 112 moves to the pushing part 13 at the corresponding end, the pushing part 13 pushes the second CCD identification piece 73 to incline to the direction of the other pushing part 13. The pushing part 13 can adopt an inverted L-shaped connecting frame, and the height of the pushing part 13 is consistent with or slightly lower than the height of the second CCD identification piece 73, so as to ensure that when the sliding block 112 moves to the pushing part 13 along the guide rail 111, the pushing part 13 can push the second CCD identification piece 73 in the opposite direction, so that the inclination direction of the second CCD identification piece 73 changes, thereby adjusting the inclination angle of the second CCD identification piece 73.

[0078] Specifically, the second CCD recognition element 73 is tilted in the opposite direction along the hinge point by the pushing part 13 that moves to either end of the guide rail 111 and is pushed by the pushing part 13, thereby adjusting the tilt angle of the second CCD recognition element 73. The V-shaped limiting block 113 provides a limit to the second CCD recognition element 73 to prevent the second CCD recognition element 73 from continuing to tilt to one side. When the second CCD recognition element 73 tilts in any direction, the recognition angle can be adjusted to ensure that the product is provided with all-round CCD recognition.

[0079] Further, refer to Figure 5 and Figure 6 As shown, the base 11 at both ends of the guide rail 111 is also provided with a guide wire section 14. The first linkage rope 632 and the second linkage rope 662 both pass around the guide wire section 14 and are connected to the slider 112. The guide wire section 14 can be composed of several guide wire loops. The first linkage rope 632 and the second linkage rope 662 can be longer by passing through the guide wire loops, so as to adapt to a longer wiping belt 65. At the same time, the guide rail 111 is also longer, which makes it easier for the second CCD recognition component 73 to provide CCD recognition from more angles, obtain more complete recognition information, and provide more accurate recognition images.
