[0048] Reference Figure 1 and Figure 2An embodiment of the present application provides a dispensing and pressing device 100. Specifically, the dispensing and pressing device 100 includes a first transmission line 10, a dispensing mechanism 20, a CCD visual inspection device 30, a mechanical arm 40 and a pressing mechanism 50. The first transmission line 10 is used to directional transmit the workpiece 200. Exemplarily, the first transmission line 10 may include a motor, a rotating shaft (may include two parallel arranged rotating shafts) and a conveyor belt. The motor drives the rotating shaft to rotate. The conveyor belt is sleeved on the periphery of the rotating shaft. The rotating shaft rotates to drive the conveyor belt to rotate, and then the conveyor belt drives the workpiece to move in a directional manner. Exemplarily, the workpiece 200 may include an on-board filter. The dispensing mechanism 20 is used to drip colloid onto the upper cover 210 of the workpiece 20. Exemplarily, the dispensing mechanism 20 may include an air pump spray gun or a screw valve dispensing gun. The CCD visual inspection device 30 is used to detect whether the upper cover 210 after glue dispensing is the first qualified part or the first unqualified part. For example, when the upper cover 210 after glue dispensing is transferred to the CCD visual inspection device 30 for inspection, the CCD visual inspection device 30 sends an OK signal, which means that the upper cover 210 is the first qualified part, and the CCD visual inspection device 30 sends an NG signal, which means that the upper cover 210 is the first unqualified part. The robot arm 40 is coupled to the CCD visual inspection device 30. For example, the signal interaction between the CCD visual inspection device 30 and the robot arm 40 can be realized through a PLC (Programmable Logic Controller) controller and / or a computer, or can be realized by wireless or wired means to achieve the coupling between the two. The robot arm 40 is used to transfer the upper cover 210 of the workpiece 200 of the first transmission line 10 to the glue dispensing mechanism 20 for glue dispensing, and is also used to transfer the upper cover 210 after glue dispensing from the glue dispensing mechanism 20 to the CCD visual inspection device 30, and is also used to transfer the upper cover 210 after qualified glue dispensing back to the bottom cover of the original workpiece. For example, the upper cover 210 with qualified glue dispensing can be moved back in front of the pressing mechanism 50, and then the two are transferred to the pressing mechanism 50 for pressing through the first transmission line 10. For example, the robot arm 40 can include a six-axis robot arm or a SCARA robot arm. It can be understood that the robot arm 40 can realize the flipping of the upper cover 210, so that the end face of the upper cover 210 that needs glue dispensing can be relative to the glue dispensing mechanism 20, and the colloid of the upper cover 210 can be flipped to the bottom cover. For example, the robot arm 40 can grab the upper cover 210 by means of a suction cup or a clamp. The pressing mechanism 50 is fixedly arranged at the output end of the first transmission line 10. Figure 3 The pressing mechanism 50 includes a connected driving member 51 and a pressing assembly 52. ​​The pressing assembly 52 is arranged relative to the transmission surface of the first transmission line 10. The driving member 51 is used to drive the pressing assembly 52 to move closer to or away from the first transmission line 10, thereby completing the pressing operation.

[0049] During specific operation, the robot arm 40 transfers the upper cover 210 to the glue dispensing mechanism 20 for glue dispensing. After glue dispensing, the upper cover 210 is transferred by the robot arm 40 to the CCD visual inspection device 30 for image inspection, so as to determine whether the glue dispensing of the upper cover 210 meets the standard. Then, the robot arm 40 transfers the qualified upper cover 210 after glue dispensing back to the original bottom cover, and then the pressing mechanism 50 presses and bonds the returned upper cover 210 and the bottom cover.

[0050] In the present application, the robot arm 40 cooperates with the first transmission line 10 and the glue dispensing mechanism 20 to realize the glue dispensing of the upper cover 210 of the workpiece 200, and further cooperates with the CCD visual inspection equipment 30. The glue dispensing and pressing device 100 can also detect whether the glue dripping of the workpiece 200 meets the standard. Further cooperate with the pressing mechanism 50, the glue dispensing and pressing device 100 can also press and bond the upper cover 210 and the bottom cover of the workpiece 200. Therefore, the glue dispensing and pressing device 100 of the present application has the function of glue dispensing and pressing, and also has the function of glue dripping detection, which is beneficial to improve the output yield of the glue dispensing and pressing device 100.

[0051] In some embodiments, reference Figure 1 and Figure 2 The glue dispensing and pressing device 100 also includes a weight sensor 60, which is used to weigh and detect whether the first qualified part is the second qualified part or the second unqualified part, that is, the weight sensor 60 can detect whether the glue dispensing amount meets the standard. Specifically, if the weight sensor 60 sends an OK signal, it means that the first qualified part is the second qualified part. If the weight sensor 60 sends an NG signal, it means that the first qualified part is the second unqualified part. Observing from the first transmission line 10 to the robot arm 40, the pressing mechanism 50, the weight sensor 60, the CCD visual inspection device 30 and the glue dispensing mechanism 20 are arranged around the robot arm 40 in sequence, thereby reducing the transfer stroke of the robot arm 40 to improve the working efficiency. The robot arm 40 is also coupled to the weight sensor 60. Similarly, the robot arm 40 and the weight sensor 60 can achieve signal interaction to achieve coupling through a PLC controller, a computer, a wireless or a wired method. The robot arm 40 is also used to transfer the first qualified part from the CCD visual inspection device 30 to the weight sensor 60. According to the OK signal sent by the weight sensor 60, the robot arm 40 is also used to transfer the second qualified part back to the original bottom cover. The cooperation between the weight sensor 60 and the CCD visual inspection device 30 can detect whether the dispensing meets the standard from the aspects of appearance and weight, so as to further improve the discharge yield of the dispensing and pressing device 100.

[0052] In some embodiments, reference Figure 1The dispensing and pressing device 100 further includes a second transmission line 71 and a third transmission line 72. For example, the second transmission line 71 and the third transmission line 72 can also use the structure of the first transmission line 10 to transport materials, which will not be described in detail. The second transmission line 71 is used to remove the first non-conforming part. The second transmission line 71 is arranged on the side of the dispensing mechanism 20 away from the CCD visual inspection device 30. The third transmission line 72 is used to remove the second unqualified part. The third transmission line 72 is arranged on the side of the weight sensor 60 away from the robot arm 40. The robot arm 40 is also used to transfer the first unqualified part from the CCD visual inspection device 30 to the second transmission line 71, and is also used to transfer the second unqualified part from the weight sensor 60 to the third transmission line 72. Specifically, according to the NG signal emitted by the CCD visual inspection device 30, the robot arm 40 transfers the first unqualified part to the second transmission line 71, and according to the NG signal emitted by the weight sensor 60, the robot arm 40 transfers the second unqualified part to the third transmission line 72, so that the unqualified parts can be classified and removed. In addition, the removal of unqualified parts with the assistance of the transmission line can shorten the operating stroke of the robot arm 40, thereby helping to improve the overall operating efficiency of the dispensing and pressing device 100.

[0053] In another embodiment, the non-conforming parts can be directly transferred to the blanking frame by the robot arm 40 .

[0054] In some embodiments, reference Figure 1 and Figure 2 The glue dispensing and pressing device 100 also includes a needle alignment instrument 81 and a first axis moving platform 91. The needle alignment instrument 81 is arranged on the side of the robot arm 40 away from the first transmission line 10. The needle alignment instrument 81 is used to detect whether the glue dispensing needle of the glue dispensing mechanism 20 is offset. Exemplarily, the needle alignment instrument 81 may include a fiber optic needle alignment instrument or a laser needle alignment instrument. The first axis moving platform 91 is connected to the glue dispensing mechanism 20. The first axis moving platform 91 is used to drive the glue dispensing mechanism 20 to move up and down along the first direction X to reciprocate away from or close to the needle alignment instrument 81. The needle alignment instrument 81 can prevent the glue dispensing needle from deviating and affecting the glue dispensing quality. Therefore, the establishment of the needle alignment instrument 81 can further improve the discharge yield of the glue dispensing and pressing device 100.

[0055] For example, refer to Figure 2, the first axis movable table 91 may include a base 911, a driving assembly 913 and a slide 912. The slide 912 is slidably connected to the base 911. Exemplarily, the slide 912 and the base 911 can be slidably connected by the cooperation of a protrusion and a groove. The driving assembly 913 is connected to the slide 912 to drive the slide 912 to reciprocate along the first direction X. Exemplarily, the driving assembly 913 may include a cylinder or a liquid cylinder, and the slide 912 is reciprocated along the first direction X by the extension and contraction of the cylinder or the liquid cylinder. The driving assembly 913 may also include a connected motor and a screw rod, and the screw rod may pass through and be screwed to the slide 912. The rotation of the motor drives the screw to rotate, and the slide 912 reciprocates along the first direction X under the action of the thread. The dispensing mechanism 20 is installed on the slide 912 of the first axis movable table 91.

[0056] In some embodiments, the dispensing mechanism 20 and the CCD visual inspection device 30 can be installed on the slide 912 of the first-axis moving table 91 at the same time, so as to achieve synchronous movement of the two.

[0057] In some embodiments, reference Figure 1 and Figure 2 The glue dispensing and pressing device 100 also includes a weighing instrument 82, a glue barrel (not shown) and a second axis moving platform 92. The weighing instrument 82 is arranged between the needle alignment instrument 81 and the weight sensor 60. The weighing instrument 82 is used to detect the glue dispensing speed of the glue dispensing mechanism 20. The glue barrel is used to be placed on the weighing instrument 82, and the glue dispensing mechanism 20 is also used to drip colloid into the glue barrel. In specific use, the glue dispensing mechanism 20 can drip a preset amount of colloid into the glue barrel according to a preset time, and then use the weighing instrument 82 to weigh the actual weight of the colloid. Finally, the difference between the preset value and the actual weighing value can be compared to determine whether there is a deviation in the glue dispensing speed of the glue dispensing mechanism 20. The second axis movable table 92 is connected to the first axis movable table 91. For example, the structure of the second axis movable table 92 can be the same as that of the first axis movable table 91, so it is not repeated here. The second axis movable table 92 is used to drive the first axis movable table 91 to reciprocate along the second direction Y perpendicular to the first direction X. For example, the base of the first axis movable table 91 can be installed on the slide of the second axis movable table 92 to realize that the second axis movable table 92 drives the first axis movable table 91 to move, and at least the second axis movable table 92 is used to transfer the dispensing mechanism 20 from the needle alignment instrument 81 to the weighing instrument 82. The establishment of the weighing instrument 82 can determine the dispensing rate of the dispensing mechanism 20, so as to further improve the dispensing yield of the dispensing and pressing device 100. In specific use, the dispensing mechanism 20 can perform the dispensing operation after the correction detection at the needle alignment instrument 81 and the dispensing speed at the weighing instrument 82.

[0058] In some embodiments, reference Figure 1 and Figure 2, the glue dispensing and pressing device 100 also includes a glue eraser 83 and a third-axis moving platform 93. The glue eraser 83 is arranged on one side of the needle-aligning device 81 away from the mechanical arm 40. The glue eraser 83 is used to erase the residual glue of the glue dispensing needle of the glue dispensing mechanism 20. The third-axis moving platform 93 is connected to the second-axis moving platform 92. The third-axis moving platform 93 is used to drive the second-axis moving platform 92 to reciprocate along the third direction Z, so that the glue dispensing mechanism 20 can also be transferred to the glue eraser 83. The third direction Z is perpendicular to the first direction X and the second direction Y. Exemplarily, the structure of the third-axis moving platform 93 can be the same as that of the first-axis moving platform 91, so it is not repeated. Specifically, the base of the second-axis moving platform 92 can be installed on the slide of the third-axis moving platform 93, so that the third-axis moving platform 93 can drive the second-axis moving platform 92 to move. The glue eraser 83 can reduce the residual glue, which is also conducive to further improving the discharge yield of the glue dispensing and pressing device 100.

[0059] Exemplarily, the glue eraser 83 may include two rotating components and a rotating belt, the rotating component may include a motor and a rotating box, the motor drives the rotating box to rotate around the central axis, and the rotating belt is rotatably sleeved between the two rotating boxes to rotate and take away the residual glue. Exemplarily, the glue eraser may also include only two rotating components, and the rotating box may be replaced by a rotating brush.

[0060] In some embodiments, in conjunction with reference Figure 3 The driving member 51 is a servo driving member. Exemplarily, the driving member 51 may include a servo cylinder, a servo hydraulic cylinder or a servo motor.

The driving member 51 is also electrically connected to the force sensor 522. In specific use, the driving member 51 may control the driving stroke according to the detection value received from the force sensor 522, so as to adjust the pressing force applied by the pressing assembly 52 to the workpiece 200, so as to avoid the pressing assembly 52 from applying too much force or too little force. Furthermore, the cooperation between the driving member 51 and the pressing assembly 52 is also conducive to further improving the discharge yield of the dispensing pressing device 100.

[0061] In some embodiments, in conjunction with reference Figure 1 and Figure 3The pressing mechanism 50 further includes at least two first guide posts 53 (four first guide posts 53 are shown in the figure) symmetrically spaced apart. The first guide posts 53 are oriented and arranged along the driving direction of the driving member 51. At least two first guide posts 53 are arranged on opposite sides of the first transmission line 10. The second pressing member 523 is slidably connected to the first guide posts 53. Exemplarily, the first guide post 53 can be arranged through the second pressing member 523, so that the driving member 51 drives the pressing assembly 52 to reciprocate along the orientation direction of the first guide posts 53. The first pressing member 521 is arranged in a space surrounded by at least two first guide posts 53. The first guide posts 53 are conducive to improving the directional movement stability of the pressing assembly 52.

[0062] In some embodiments, reference Figure 3 The second pressing member 523 includes a body 5231 and two first stoppers 5232 arranged at intervals. The body 5231 is slidably connected to the first guide column 53, and the force sensor 522 is fixed between the body 5231 and the first pressing member 521. The two first stoppers 5232 are both arranged on the end surface of the body 5231 away from the first pressing member 521. The first stoppers 5232 are arranged in a space surrounded by at least two first guide columns 53. The two first stoppers 5232 and the body 5231 jointly form a card slot 510. The card slot 510 has a first slot portion 511 and a second slot portion 512 that are connected. The body 5231 forms the bottom wall of the second slot portion 512. The aperture of the second slot portion 512 is larger than the aperture of the first slot portion 511. The pressing mechanism 50 further includes a second stopper 54, which is convexly disposed on the circumferential surface of the output shaft of the driving member 51, and the second stopper 54 abuts against the second groove 512. The driving member 51 is engaged with the second pressing member 523 through the second stopper 54 to achieve connection, which is conducive to fine-tuning the connection gap between the first guide column 53 and the second pressing member 523, thereby preventing the first guide column 53 and the second pressing member 523 from locking, and further facilitating the pressing smoothness of the dispensing pressing device 100.

[0063] In some embodiments, the pressing assembly 52 further includes at least two second guide posts 524 (two second guide posts 524 are shown in the figure) symmetrically spaced apart, the second guide posts 524 are convexly disposed on the second pressing member away from the driving member 51, specifically, the second guide posts 524 are convexly disposed on the body 5231, the second guide posts 524 are disposed parallel to the first guide posts 53, the first pressing member 521 is slidably connected to the second guide posts 524, and illustratively, the second guide posts 524 can be disposed through the first pressing member 521. The second guide posts 524 are conducive to improving the positioning accuracy of the first pressing member 521.

[0064] In some embodiments, the pressing mechanism 50 further includes at least two guide cylinders 55, each of which is disposed on the periphery of a first guide column 53, and the guide cylinder 55 includes a first cylinder portion 551 and a second cylinder portion 552 which are connected and stacked, the circumferential outer surface of the first cylinder portion 551 protrudes from the circumferential outer surface of the second cylinder portion 552, and the first cylinder portion 551 can be detachably connected to the second pressing piece 523 through a connecting nail, specifically, the first cylinder portion 551 is detachably connected to the body 5231 of the second pressing piece 523 through a connecting nail, and the second cylinder portion 552 passes through the second pressing piece 523, specifically, the second cylinder portion 552 passes through the body 5231 of the second pressing piece 523.
