Description

Technical Field

[0001] This utility model relates to the field of photosensitive adhesive technology, specifically to a photosensitive adhesive raw material grinding device. Background Technology

[0002] With the advancement of semiconductor packaging technology towards the nanoscale, the surge in demand for photosensitive adhesives for photovoltaic cells, and the increasing demand for micro-line processing capabilities in high-end printing, the particle size uniformity, dispersion stability, and production efficiency of photosensitive adhesive raw materials have become key technological bottlenecks restricting the industry's development.

[0003] Traditional grinding devices often employ fixed-interval grinding chambers or single-speed sand mills, making it difficult to achieve precise control of submicron particle size. For example, a grinding device disclosed in a patent adjusts the tension of the grinding workpiece using guide rollers, but wear on the grinding surface easily leads to a broadening of the particle size distribution, with the average length deviation of surface roughness curve elements exceeding ±20%, failing to meet the resolution requirements of photosensitive adhesives in semiconductor packaging.

The surfaces of the inclined guide plates are inclined inward to guide the input of the photosensitive adhesive raw material. Three drive shafts are rotatably disposed between the two walls of the working chamber. The three drive shafts are arranged in a semi-circular arc array, and grinding rollers are fixedly disposed on the outer end faces of the drive shafts. The three grinding rollers cooperate to achieve the raw material grinding effect.

Detailed Implementation

[0024] This utility model embodiment provides a photosensitive adhesive raw material grinding device, such as... Figure 1-4 As shown, the device includes a grinding device body 101, an inclined guide plate 105, and a raw material guide plate 109. The grinding device body 101 has a working cavity 107 with an outward opening. The raw material guide plate 109 is fixedly disposed between the two walls below the working cavity 107. The raw material guide plate 109 is used to guide the ground photosensitive emulsion material for output. Two inclined guide plates 105 are fixedly disposed at the top of the working cavity 107. The inclined guide plates 105 on both sides are symmetrically arranged. The surface of the inclined guide plates 105 is inclined inward to guide the input of the photosensitive emulsion material. Three drive shafts 103 are rotatably disposed between the two walls of the working cavity 107. The three drive shafts 103 are arranged in a semi-circular arc array. Grinding rollers 106 are fixedly disposed on the outer end face of the drive shafts 103. The three grinding rollers 106 cooperate to achieve the grinding effect of the raw material.

[0025] Furthermore, the grinding device body 101 has a gearbox groove 102 with an outward opening on one side, and one end of the three drive shafts 103 extends into the gearbox groove 102 and is fixedly connected to meshing gears 104, with the meshing gears 104 on each side meshing with each other.

[0026] Furthermore, a power motor 111 is fixedly installed on the other side of the grinding device body 101, and the power motor 111 is poweredly connected to the transmission shaft 103 on the middle side.

[0027] It should be further explained that when the power motor 111 starts, it can drive the transmission shaft 103 on one side through the power connection. At this time, the transmission shaft 103 drives the meshing gear 104 located below to rotate. The meshing gear 104 below drives the meshing gears 104 on the other two sides to rotate through gear meshing. The rotation of the meshing gears 104 on the other two sides drives the connected transmission shaft 103 to rotate, thereby driving the three grinding rollers 106 to rotate. At this time, the rotation direction of the grinding rollers 106 on the upper two sides is opposite to the rotation direction of the grinding rollers 106 below.

[0028] Furthermore, a control shaft 115 is rotatably provided between the two walls of the working chamber 107 and on one side of the raw material guide plate 109. A flip guide plate 110 is fixedly connected to the outer end face of the control shaft 115. One end of the control shaft 115 extends outward to one side of the grinding device body 101 and is connected to a hand-held turntable 112.

[0029] It should be further explained that a torsion spring is installed between the handheld turntable 112 and the grinding device body 101. After the tilting guide plate 110 is rotated and in an inclined state, as... Figure 4 As shown, one side of the raw material guide plate 109 is blocked at this time, so that a certain amount of photosensitive emulsion grinding material can be stored at the top of the raw material guide plate 109, which is suitable for photosensitive emulsion materials that need to be repeatedly ground.

[0030] Furthermore, two fixed supports 108 are fixedly provided on both sides inside the working cavity 107. The fixed supports 108 on both sides are symmetrically arranged, and the lower end of the fixed supports 108 is inclined.

[0031] Furthermore, several cooling nozzles 116 are fixedly arranged on the lower side of the fixed brackets 108 on both sides, close to each other, and the cooling nozzles 116 are arranged in an array.

[0032] It should be further explained that the cooling nozzle 116 opens towards the grinding contact position between the bottom grinding roller 106 and the two upper grinding rollers 106, and the cooling nozzle 116 is connected to the coolant input pump.

[0033] Furthermore, two infrared temperature monitors 114 are installed on the two side walls of the working chamber 107, with their detection heads facing the grinding contact positions of the grinding rollers 106 on each side.

[0034] It is worth further explaining that the infrared temperature monitor 114 is used to monitor the temperature of the grinding contact position of the grinding roller 106. When the temperature is abnormal, it controls the cooling nozzles 116 on each side to start and cool the grinding contact position through a signal connection.

[0035] The usage method of this solution is as follows:

[0036] S1. First, the grinding device body 101 is moved to the working position, and the power motor 111 is started to drive the intermediate transmission shaft 103 to rotate. Through the meshing action of the meshing gears 104, the transmission shafts 103 on both sides above are driven to rotate synchronously in opposite directions, thereby driving the three grinding rollers 106 to rotate in a preset direction. The photosensitive adhesive material to be ground is put into the working chamber 107 from the top opening of the grinding device body 101. The put-in material first falls on the two fixed inclined guide plates 105. Since their surfaces are inclined inward, the material is naturally guided and concentrated into the grinding area entrance formed by the three rotating grinding rollers 106.

[0037] S2. The raw material falling into the grinding area is squeezed, sheared, and ground by three rotating grinding rollers 106. After the initial grinding, the material falls downward under the action of gravity and the movement of the rollers, and the ground material falls directly onto the fixed raw material guide plate 109. The raw material guide plate 109 guides the material to the outlet below the working chamber 107 for output, completing one grinding process. This mode is suitable for materials that do not require high grinding fineness or only need to be ground once.

[0038] S3. For photosensitive adhesive raw materials that require higher fineness or repeated grinding, the operator rotates the hand-held turntable 112 on one side of the grinding device body 101. The hand-held turntable 112 drives the control shaft 115 to rotate, thereby causing the flip guide plate 110 fixedly connected to the control shaft 115 to rotate downward to an inclined state. In this state, the lower edge of the flip guide plate 110 approaches or contacts the side of the raw material guide plate 109, forming a physical barrier. The material that falls on the raw material guide plate 109 after the first grinding is blocked by the flip guide plate 110 and cannot slide directly to the discharge port, but accumulates in the top area of ​​the raw material guide plate 109.

[0039] S4. Then the staff will take out the material accumulated at the top of the raw material guide plate 109 and put it back into the grinding area formed by the two upper grinding rollers 106 and the lower grinding roller 106 for grinding again. This process can be repeated many times. The material is continuously fed back into the grinding area in the blocking area until the required grinding fineness is achieved.

[0040] S5. After the material has been repeatedly ground to meet the requirements, the operator rotates the hand-held turntable 112 in the opposite direction to remove the obstruction to the material on the raw material guide plate 109. The material that has reached the fineness requirement then slides smoothly along the inclined surface of the raw material guide plate 109 to the outlet below the working chamber 107 for output and collection.

[0041] S6. During the grinding process, the infrared temperature monitors 114, which are fixedly installed on both sides of the working chamber 107, continuously monitor the temperature of the grinding contact points between each grinding roller 106. When the temperature of any grinding contact point exceeds the preset safety or process threshold, the infrared temperature monitor 114 sends a signal. This signal controls the cooling nozzles 116 connected to the coolant input pump to start. The cooling nozzles 116 arranged in an array below the fixed bracket 108 accurately spray coolant onto the corresponding grinding contact position of the grinding roller 106 with abnormal temperature for rapid and directional cooling to prevent the material from deforming or the equipment from being damaged due to overheating. When the temperature drops back to the safe range, the cooling nozzles 116 stop spraying.

[0042] S7. After the grinding operation is completed, turn off the power motor 111. Necessary cleaning work can be carried out through the opening of the working chamber 107 to remove residual materials.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
