[0026] First embodiment:
[0027] This embodiment discloses a conductive silver paste dispensing device.
[0028] like Figure 1 As shown, the system includes a control housing 1, a pump body 3, a bracket 2, a feeding hopper 4, a syringe 5, a first pneumatic cylinder 61, an upper limit position sensor 63, and a lower limit position sensor 64. The pump body 3 is mounted on the control housing 1. The bracket 2 is vertically mounted on the upper part of the control housing 1. The feeding hopper 4 contains material, and its lower end is connected to the input end of the pump body 3. The syringe 5 is detachably mounted on the front end of the bracket 2 and has a first piston rod 52 that can slide within the syringe 5. Its lower end has a nozzle 51, which is connected to the output end of the pump body 3. The first pneumatic cylinder 61 is located at the front end of the bracket 2, above the syringe 5, and has a retractable second piston rod 62 at its lower end, with the lower end of the second piston rod 62 abutting against the upper end of the first piston rod 52. The upper limit position sensor 63 and the lower limit position sensor 64 are located on the side of the first pneumatic cylinder 61, respectively detecting the first and second positions of the second piston rod 62.
[0029] For example, the feed container 4 is fixed to the side of the bracket 2, and the material is conductive silver paste. The syringe 5 is snapped and fixed to the bracket 2. Specifically, the bracket 2 also includes a retaining ring 22, which is fixedly disposed at the front end of the bracket 2, with the opening of the retaining ring 22 facing the front end. The syringe 5 is vertically snapped into the retaining ring 22, and the lower end of the outer edge 53 abuts against the upper surface of the retaining ring 22.
[0030] like Figure 1 As shown, the retaining ring 22 further includes a syringe sensor 221, which is disposed on the retaining ring 22. The syringe sensor 221 is triggered when the outer edge 53 of the syringe 5 is placed on the retaining ring 22.
[0031] like Figure 1 As shown, the pump body 3 further includes a throttle valve 31, which is disposed on the pump body 3 to control the flow rate of the pumped material.
[0032] like Figure 1 and Figure 4 As shown, furthermore, a controller 8 is installed inside the control box 1. The controller 8 is electrically connected to the pump body 3, the first pneumatic cylinder 61, the upper limit position sensor 63, the lower limit position sensor 64, the syringe sensor 221, and the throttle valve 31. In this application, electrical connection refers to the form in which different components in the circuit are connected through physical lines capable of transmitting electrical signals, such as PCB copper foil or wires. The controller 8 receives the detection signals from the syringe sensor 221, the upper limit position sensor 63, and the lower limit position sensor 64 and controls the start and stop of the pump body 3 and the first pneumatic cylinder 61.
[0033] like Figure 1 As shown, furthermore, the control box 1 is also equipped with a button 11 and an indicator light 12, which are electrically connected to the controller 8 respectively.
[0034] like Figure 2 and Figure 3 As shown, in this embodiment, an empty syringe 5 is inserted into a retaining ring 22, with the lower end of its outer edge 53 abutting against the upper surface of the retaining ring 22, triggering the syringe sensor 221. The nozzle 51 is connected to the output end of the pump body 3. The controller 8 receives the detection signal from the syringe sensor 221 and starts the first pneumatic cylinder 61. The second piston rod 62 presses down the first piston rod 52 to the first position, triggering the lower limit position sensor 64. The controller 8 receives the detection signal from the lower limit position sensor 64 and stops the first pneumatic cylinder 61, starting the pump body 3. The pump body 3 pumps material into the syringe 5, and the first piston rod 52 pushes the second piston rod 62 to the second position. The second piston rod 62 triggers the upper limit position sensor 63. The controller 8 receives the detection signal from the upper limit position sensor 63 and stops the pump body 3, completing the filling process. The conductive silver paste dispensing equipment in this embodiment has a simple structure and is easy to use. By setting the upper and lower limits to determine the moving distance of the first piston rod 52, the weight of the conductive silver paste dispensing can be precisely controlled.
[0035] Second embodiment:
[0036] Based on the first embodiment, the second embodiment has been further optimized and refined.
[0037] The conductive silver paste dispensing equipment also includes a second pneumatic cylinder 71 and a pressure block 73. The second pneumatic cylinder 71 is located at the upper end of the support 2, and has a retractable third piston rod 72 at its lower end. The pressure block 73 is connected to the lower end of the third piston rod 72. The first pneumatic cylinder 61 is located at the upper end of the pressure block 73, and the second piston rod 62 passes through the pressure block 73 and the retaining ring 22.
[0038] like Figure 1 As shown, the conductive silver paste dispensing equipment further includes a damper 23 and a pressure sensor 74. The damper 23 is disposed at the front end of the bracket 2, and the pressure sensor 74 is disposed at the lower end of the pressure block 73. The pressure block 73 presses against the outer edge 53 while simultaneously squeezing the damper 23. For example, the controller 8 is electrically connected to the second pneumatic cylinder 71 and the pressure sensor 74.
[0039] like Figure 1 As shown, a guide rail (not shown in the figure) is further provided at the front end of the bracket 2, and the second pneumatic cylinder 71 is slidably connected to the guide rail. The conductive silver paste dispensing device also includes a fixing block 75, which is connected to both the side of the second pneumatic cylinder 71 and the side of the bracket 2, so as to facilitate the adjustment and fixing of the position of the second pneumatic cylinder 71 to accommodate syringes 5 of different sizes.
[0040] In this embodiment, an empty syringe 5 is inserted into a retaining ring 22, with the lower end of its outer edge 53 abutting against the upper surface of the retaining ring 22. The nozzle 51 is connected to the output end of the pump body 3. The controller 8 receives a detection signal from the syringe sensor 221 and activates the second pneumatic cylinder 71. The third piston rod 72 extends, driving the pressure block 73 to move downward, so that the outer edge 53 is clamped and fixed between the pressure block 73 and the retaining ring 22 to secure the syringe 5. At the same time, the controller 8 receives a detection signal from the pressure sensor 74 and stops the second pneumatic cylinder 71 to avoid excessive pressure and damage to the equipment.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
