[0006] Furthermore, the above automatic dispensing machine has a sinking platform on the workbench. The bearing plate is detachably installed in the sinking platform. The detachable bearing plate design facilitates the replacement of different bearing plates to adapt to workpieces of different sizes.

[0007] Furthermore, in the automatic dispensing machine, the limiting member includes a first limiting member and a second limiting member. Two sides of the workpiece are limited by the first limiting member, and the other two sides are limited by the second limiting member.

The ball bearing is fixed to the slider, and the ball bearing is sleeved on the position of the ball screw with the spiral groove. The ball screw rotates, driving the ball bearing to move along the ball screw, thereby driving the slider to move along the guide rail.

[0011] Furthermore, in the automatic glue dispensing machine, the linear moving mechanism also includes a motor and a coupling. One end of the coupling is fixed to the output shaft of the motor, and the other end is fixed to one end of the ball screw. The motor drives the coupling to rotate, and the coupling drives the ball screw to rotate. Further, in the automatic glue dispensing machine, the glue dispensing device includes a back plate, at least one tube clamp, a glue storage tube and a nozzle.

The lower end of the glue storage tube is connected to a nozzle, and an air pipe interface is provided at the center of the upper end of the glue storage tube for connecting power gas. The glue storage tube is clamped by the tube clamp, and the tube clamp is fixed on the back plate. The back plate is fixed to the Z-axis linear moving mechanism, and the glue dispensing device and the mobile device are tightly connected together, so that the mobile device becomes a mobile carrier of the glue dispensing device. During the glue dispensing operation, the mobile device brings the glue dispensing device to the area where the glue dispensing operation is required, and the nozzle is aimed at the workpiece to start the glue dispensing operation. In addition, the power gas is connected through the air pipe interface to control the colloid in the glue storage tube to flow out from the nozzle to the workpiece.

[0012] Furthermore, in the automatic glue dispensing machine, the pipe clamp includes a semi-circular outer ring body and a semi-circular inner ring body. One side of the outer ring body is fixed to the back plate, one end of the outer ring body is hingedly connected to one end of the inner ring body, and the other end of the outer ring body is fastened to the other end of the inner ring body by an adjusting screw.

[0033] Example 2

[0034] The automatic glue dispensing machine provided by the utility model can be used for glue dispensing and packaging scenes of workpieces such as microelectronic components, semiconductors, optical instruments, etc.

[0035] like Figure 1 The automatic glue dispensing machine shown comprises a workbench 1, a mobile device 2 and a glue dispensing device 3. The workbench 1 has a carrier plate 11, and a cover plate 12 is provided on the carrier plate 11. The mobile device 2 is arranged on the workbench 1, and the glue dispensing device 3 is arranged on the mobile device 2, and the mobile device 2 carries the glue dispensing device 3 and moves above the workbench 1.

[0036] like Figure 2As shown, there are raised limiters on the carrier plate 11, which define the workpiece placement area for placing the workpieces to be glued, provide a fixed placement position for the workpieces, help the operator to place the workpieces quickly and accurately, and improve work efficiency.

[0037] like Figure 3 As shown, through holes 121 corresponding to the workpiece placement area are provided on the cover plate 12. The cover plate 12 presses the carrier plate 11 from above, and the through holes 121 on the cover plate 12 expose the area to be glued on the workpiece, limiting the workpiece placement area from above.

[0038] In addition, the automatic dispensing machine in this embodiment is also connected to the control unit. By pre-setting the moving path of the dispensing device 3 and the points where it needs to stop during dispensing, the moving device 2 and the dispensing device 3 can complete the dispensing operation without human intervention, thereby reducing the need for manual operation.

[0039] like Figure 4 As shown, a sinking platform 13 is provided on the workbench 1, and a bearing plate 11 is detachably installed in the sinking platform 13. The detachable bearing plate 11 is designed to facilitate replacement of different bearing plates 11 to adapt to workpieces of different sizes.

[0040] like Figure 2 As shown, the limiting member includes a first limiting member 1111 and a second limiting member 1112. Two ends of the workpiece are limited by the first limiting member 1111, and the other two ends are limited by the second limiting member 1112. The area defined by the first limiting member 1111 and the second limiting member 1112 is the workpiece placement area. The first limiting member 1111 and the second limiting member 1112 accurately locate the workpiece placement area from multiple directions to reduce the deviation of the workpiece.

[0041] like Figure 2 As shown, two positioning holes 112 are provided on both sides of the carrier plate 11. Figure 3 As shown, two positioning bosses 122 are provided on both sides of the cover plate 12. When the cover plate 12 is pressed on the carrier plate 11, the positioning bosses 122 are embedded in the positioning holes 112. The cover plate 12 is fixed on the carrier plate 11 by the upper and lower engagement of the positioning holes 112 and the positioning bosses 122, thereby increasing the stability of the structure and ensuring that the position of the cover plate 12 on the carrier plate 11 is stable and will not shake.

[0042] like Figure 5As shown, the moving device 2 includes four linear moving mechanisms. Each linear moving mechanism includes a mechanism body 21, a slider 22 and a power unit. The mechanism body 21 is in the shape of a long strip; the slider 22 is slidably arranged on the mechanism body 21; the power unit drives the slider 22 to slide along the mechanism body 21. Among them, a pair of linear moving mechanisms are arranged in parallel on the workbench 1, which are denoted as X-direction linear moving mechanisms; another linear moving mechanism is arranged in a direction perpendicular to the X-direction linear moving mechanism and parallel to the workbench 1, which is denoted as Y-direction linear moving mechanism; another linear moving mechanism is arranged in a direction perpendicular to the workbench 1, which is denoted as Z-direction linear moving mechanism; the two ends of the mechanism body 21 of the Y-direction linear moving mechanism are respectively fixed on the sliders 22 of the X-direction linear moving mechanism on both sides; the mechanism body 21 of the Z-direction linear moving mechanism is fixed on the slider 22 of the Y-direction linear moving mechanism; the dispensing device 3 is fixed on the slider 22 of the Z-direction linear moving mechanism. Through the linear moving mechanism in three directions of X, Y, and Z, the moving device 2 can align the dispensing device 3 to all positions within the surface of the workbench 1, so as to realize dispensing at different positions on the workbench 1.

[0043] like Figure 6 As shown, in the automatic dispensing machine of this embodiment, each linear moving mechanism includes two fixed blocks 212, a guide rail 213, a ball screw 216 and a ball bearing 217; the fixed block 212 has a central opening and is arranged at both ends of the mechanism body 21; the guide rail 213 is arranged on both sides of the mechanism body 21, and a slide groove is arranged at the bottom of the slider 22, and the guide rail 213 is engaged with the slide groove at the bottom of the slider 22; the two ends of the ball screw 216 are rotatably mounted in the fixed block 212 through bearings; the surface of the ball screw 216 located between the two end fixed blocks 212 is provided with a spiral groove; the ball bearing 217 is fixed to the slider 22; the ball bearing 217 is sleeved on the position of the ball screw 216 with the spiral groove. The ball screw 216 rotates, driving the ball bearing 217 to move along the ball screw 216, thereby driving the slider 22 to move along the guide rail 213.

[0044] A ball is arranged on the inner circumference of the ball bearing 217, and the ball moves in a circular motion along the spiral groove on the surface of the ball screw 216. Since the spiral groove of the ball screw 216 has an angle, the ball screw 216 squeezes the ball when it rotates, generating a reaction force to move the ball bearing 217. The forward and reverse rotation of the ball screw 216 can control the moving direction of the ball bearing 217. The fixed block 212 is connected to the ball screw 216 through a bearing, so the fixed block 212 does not move with the rotation of the ball screw 216.

[0045] When the ball screw 216 rotates clockwise, the balls inside the ball bearing 217 rotate along the spiral groove on the surface of the ball screw 216. The balls are subjected to pressure from the inner wall of the spiral groove, generating a reaction force that moves the ball bearing 217 to one side, thereby driving the slider 22 to move on the guide rail 213; similarly, when the ball screw 216 rotates counterclockwise, the balls inside the ball bearing 217 rotate along the spiral groove on the surface of the ball screw 216. The balls are subjected to pressure from the inner wall of the spiral groove, generating a reaction force that moves the ball bearing 217 to the other side, thereby driving the slider 22 to move in the opposite direction on the guide rail 213.

[0046] like Figure 6 As shown, the linear motion mechanism further includes a motor 231 and a coupling 232. One end of the coupling 232 is fixed to the output shaft of the motor 231, and the other end is fixed to one end of the ball screw 216. The motor 231 drives the coupling 232 to rotate, and the coupling 232 drives the ball screw 216 to rotate.

[0047] The motor 231 is preferably equipped with a servo motor with a sensor and a brake, and is connected to an external control system. The external control system transmits a signal of forward rotation, reverse rotation or stop rotation to the motor 231, and controls the slider 22 to move or stop on the linear motion mechanism. The coupling 232 connects the motor 231 and the ball screw 216 to ensure that the ball screw 216 rotates with the motor 231. By setting the motor 231 and connecting the motor 231 with the ball screw 216, the motor 231 drives the ball screw 216 to rotate, thereby realizing the function of the linear motion mechanism.

[0048] like Figure 7 As shown, the glue dispensing device 3 includes a back plate 31, two tube clamps 32, a glue storage tube 33 and a nozzle 34. The back plate 31 is fixed on the slider 22 of the Z-axis linear moving mechanism, and one side of the tube clamp 32 is fixed on the back plate 31. The tube clamp 32 has a receiving hole in the center, and the glue storage tube 33 is inserted into the receiving hole in the center of the tube clamp 32 and clamped by the tube clamp 32. The lower end of the glue storage tube 33 is connected to the nozzle 34, and the center of the upper end of the glue storage tube 33 is provided with an air pipe interface 332 for connecting the power gas.

[0049] The glue storage tube 33 is clamped by the tube clamp 32, and the tube clamp 32 is fixed on the back plate 31. The back plate 31 is fixed to the slider 22 on the Z-axis linear moving mechanism, which connects the glue dispensing device 3 with the mobile device 2, so that the mobile device 2 becomes the mobile carrier of the glue dispensing device 3. During the glue dispensing operation, the mobile device 2 brings the glue dispensing device 3 to the area where the glue dispensing operation is required, and the nozzle 34 is aimed at the workpiece to start the glue dispensing operation. In addition, the glue storage tube 33 is connected to the external air pressure device through the air pipe interface 332. By increasing the air pressure in the glue storage tube 33, the colloid in the glue storage tube 33 is dispensed onto the workpiece by the nozzle 34.

[0050] like Figure 8As shown, the pipe clamp 32 includes a semi-circular outer ring body 321 and a semi-circular inner ring body 322. One side of the outer ring body 321 is fixed to the back plate 31, one end of the outer ring body 321 is hingedly connected to one end of the inner ring body 322, and the other end of the outer ring body 321 is fastened to the other end of the inner ring body 322 by an adjusting screw.

[0051] The outer ring body 321 and the inner ring body 322 are fixed by a hinge at one place and a screw at another place, which is simple and reliable, easy to install and disassemble, and can ensure that the operator can easily disassemble or install them, thereby facilitating operations such as maintenance and replacement of the dispensing device 3.

[0052] like Figure 8 As shown, two pairs of wing-shaped protruding limiting steps 331 are radially provided on the circumference of the rubber storage tube 33 , and the lower ends of the limiting steps 331 are placed on the upper surface of the tube clamp 32 .

[0053] The limiting step 331 can resist the tube clamp 32, limit the displacement of the glue storage tube 33 in the vertical direction, enhance the stability of the glue dispensing device 3, and ensure the accuracy of the glue dispensing operation.
