Description

Technical Field

[0001] The utility model relates to the technical field of chip production, in particular to an AB glue dispensing device for a chip. Background Art

[0002] When assembling detectors for receiving X-rays in medical or industrial testing equipment, it is usually necessary to use glue to accurately attach the anti-scatter grid to the surface of the X-ray receiving chip. In order to facilitate the dispensing of glue on the surface of the chip, workers usually use a chip AB dispensing glue device. The existing chip AB dispensing glue device usually consists of a workbench, a glue supply device and a dispensing head.

[0003] For example, the utility model with application number CN202322279095.2 discloses an AB glue dispensing machine, comprising a workbench, specifically comprising a bracket installed at the upper end of the workbench, a barrel A fixedly installed at the left end of the bracket, and a barrel B fixedly installed at the right end of the bracket. The utility model can add the liquid inside barrels A and B to the inside of a mixing barrel through a first output pipe by twisting a first valve. By referring to the scales set on barrels A and B, the amount of liquid added inside barrels A and B can be accurately controlled, and the mixture can be well mixed according to a certain proportion. The rotating spiral blade can stir the mixed liquid inside the mixing barrel and surge upward. At the same time, the rotating stirring plate can stir the interior of the lower end of the mixing barrel, so that there is no dead angle in the stirring, the stirring and mixing effect is better, and there is no large-scale direct contact with the outside air during the entire stirring and mixing process. At the same time, the AB glue is directly sealed and transported to the inside of the glue storage pipe through the second output pipe.

[0004] However, as far as the current traditional chip AB glue dispensing device is concerned, during the dispensing process, in order to ensure that the AB glue is accurately coated on the chip, it is usually necessary to adjust the chip position multiple times to make the dispensing head in the center of the chip to achieve the ideal coating effect. This increases production time and cost and is inconvenient to use. Utility Model Content

[0005] In view of this, the utility model provides a chip AB glue dispensing device, which has an identification camera and an altimeter that can quickly locate the center of the chip. The altimeter can be set to calibrate the position difference and height difference between the dispensing head and the identification camera and the altimeter, so that in automatic production, the dispensing head can be moved to above the center of the chip photographed by the identification camera, and the Z axis can be moved to the height position measured by the altimeter. After the height positioning is completed, the light source is provided to the identification camera through the light source body, and the identification camera is moved to the four edge positions of the chip, and a picture is taken to search for a straight line, and the outer contour rectangle of the chip is fitted to find the center position, so that the dispensing head can accurately dispense AB glue in the specified area.

[0029] This utility model proposes a chip AB glue dispensing device, please refer to Figures 1 to 8 , including: gantry bracket 1;

[0030] A feeding track 101 is provided at the lower part of the gantry bracket 1; a linear module 102 is fixedly connected to the front end face of the gantry bracket 1; a transverse sliding seat 103 is provided at the front end face of the linear module 102; a mounting seat 104 is fixedly connected to the front end face of the transverse sliding seat 103; a first driving motor 105 is fixedly connected to the top end face of the mounting seat 104; a first lifting screw 106 is coaxially fixedly connected to the lower part of the rotating shaft of the first driving motor 105; a lifting slide 107 is connected to the external thread of the first lifting screw 106; the lifting slide 107 is slidably connected to the outside of the mounting seat 104; a rubber eraser seat 118 is fixedly connected to the outside of the feeding track 101; a lifting frame 121 is provided on the inner side of the feeding track 101.

[0031] A third mounting plate 115 is fixedly connected to the left side of the lifting slide 107; an identification camera 116 is fixedly connected to the front end plate of the third mounting plate 115; a light source body 117 is provided outside the identification camera 116; a second mounting plate 113 is fixedly connected to the center of the front end surface of the lifting slide 107; and an altimeter 114 is fixedly connected to the front of the second mounting plate 113.

[0032] The right part of the lifting slide 107 is fixedly connected to the first mounting plate 108; the right part of the first mounting plate 108 is provided with a glue feeding device 109; the lower part of the first mounting plate 108 is provided with a glue head 111; the glue outlet of the glue feeding device 109 is provided with a glue feeding pipe 110; the end of the glue feeding pipe 110 is provided in the glue dispensing head 111; the upper part of the glue dispensing head 111 is provided with a glue dispensing valve 112.

[0033] A driving cylinder 119 is fixedly connected to the upper portion of the eraser seat 118 ; a clamping seat 120 is fixedly connected to the top end surface of the output shaft of the driving cylinder 119 .

[0034] The lower part of the lifting frame 121 is bolted to a second driving motor 122; the upper part of the rotating shaft of the second driving motor 122 is coaxially fixedly connected to a second upgrading screw 123; the external thread of the second upgrading screw 123 is connected to a lifting slide 124; the lifting slide 124 is slidably connected to the outside of the lifting frame 121; the inner side of the lifting slide 124 is fixedly connected to a lifting platform 125.

[0035] The specific usage and function of this embodiment are as follows: when the chip is transported to the dispensing area, the dispensing head 111 is moved laterally by the linear module 102, and the first lifting screw 106 is driven to rotate by the first drive motor 105. The rotation of the first lifting screw 106 drives the lifting slide 107 to move, thereby causing the dispensing head 111 to move longitudinally. Subsequently, the light source body 117 provides light to the recognition camera 116, and the recognition camera 116 moves to the four edge positions of the chip, takes pictures to search for straight lines, and fits the outer contour rectangle of the chip to find the center position. If the center position is (a1, a2) during programming, the starting position for glue painting is (b1, b2), the center position during production is (c1, c2), and the recognized angle is Ag, then according to the formula, the starting position for glue painting during production (d1, d2) is:

[0036] d1=c1+sqrt((b2-a2)^2+(b1-a1)^2)*cos(Ag+arctan((b2-a2) / (b1-a1)))d2=c2+sqrt((b2-a2)^2+(b1-a1)^2)*sin(Ag+arctan((b2-a2) / (b1-a1))),

[0037] The dispensing head 111 can accurately apply AB glue to the designated area. The position difference and height difference between the dispensing head 111, the recognition camera 116, and the altimeter 114 can be calibrated by setting the altimeter 114. In this way, during automatic production, the dispensing head 111 can be moved to the center of the chip captured by the recognition camera 116, and the Z axis can be moved to the height position measured by the altimeter 114. For example:

[0038] (Position of dispensing head 111)f=(Current position of recognition camera 116)g+(Marked position of dispensing head 111)j-(Marked position of recognition camera 116)k,

[0039] After the dispensing head 111 moves to the top of the identified chip, AB glue is supplied to the dispensing head 111 through the glue feeding device 109 to dispense glue on the chip. At the same time, the dispensing amount of AB glue can be controlled by the setting of the dispensing valve 112, so that the dispensing amount of AB glue is more uniform. The eraser block can be placed through the clamping seat 120. After the dispensing is completed, the dispensing head 111 is moved to the top of the clamping seat 120 through the linear module 102, and then the driving cylinder 119 is started to lift the clamping seat 120, so that the eraser block placed in the clamping seat 120 wipes the dispensing head 111. The second upgrade screw 123 is driven to rotate by starting the second drive motor 122, and the rotation of the second upgrade screw 123 drives the lifting slide 124 to move upward. In the process of the lifting slide 124 moving upward, the lifting platform 125 will lift the chip to facilitate dispensing.
