Technical Field

[0001] This utility model relates to the field of fully automatic dicing machine technology, and in particular to a fully automatic dicing machine with pick-up and put-out function. Background Technology

[0002] In the production of solar cells, it is often necessary to divide and cut standard solar cell wafers into small pieces of different specifications. The commonly used cutting equipment is a laser scribing machine. Before cutting the solar cells, the cells need to be taken out of the hopper and placed on the laser cutting table. However, a release liner needs to be placed between two adjacent solar cells in the hopper to prevent scratches. After scribing, release liner also needs to be placed between adjacent solar cells. Current technology usually uses a robotic arm or manual handling to pick up and place the cells, which increases production costs and reduces scribing efficiency. Therefore, it is necessary to design a device that can automatically pick up and place the release liner to solve this problem. Utility Model Content

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. Two sets of positioning platform assemblies are slidably connected in parallel on the base based on a first lead screw slide. A release paper collection box and a feeding box are arranged in parallel at the material picking station of the base, and a release paper feeding box and a finished product unloading box are arranged in parallel at the material receiving station of the base. Simultaneously, a first adsorption conveying assembly and a second adsorption conveying assembly are arranged in parallel at the material picking and receiving stations based on a third lead screw slide. When material picking is required, the third lead screw slide assembly drives the first and second adsorption conveying assemblies to move synchronously. The second adsorption conveying assembly sucks out the solar cells from the feeding box and conveys them to the positioning platform assembly for positioning. At the same time, the first adsorption conveying assembly sucks out the release paper from the feeding box and conveys it to the release paper collection box to complete the collection of the release paper. After material picking is completed, the first lead screw slide drives the positioning platform assembly to move synchronously. The positioning stage moves to the dicing station located at the bottom of the laser dicing assembly. The second lead screw slide drives the laser dicing assembly to dic the solar cells fixed on the dicing stage. After dicing, the first lead screw slide drives the positioning stage assembly to the receiving station. The third lead screw slide at the receiving station drives the second adsorption conveying assembly to move directly above the positioning stage assembly and adsorbs and conveys the diced solar cells into the finished product unloading box. At the same time, the first adsorption conveying assembly takes the release paper from the release paper supply box and places it between the solar cells. The third lead screw slide drives the first and second adsorption conveying assemblies to move in coordination, thereby realizing the synchronous conveying and loading of the release paper and solar cells. The structure is simple, reduces production costs, and increases dicing efficiency.

[0016] 2. Several adsorption holes are opened on the slicing stage and adsorption pipes are connected to the outside along the Y direction. A large amount of dust is generated during the dicing process of solar cells. The dust generated during dicing is adsorbed and discharged through the adsorption pipes and adsorption holes, which reduces air pollution and also prevents dust from entering the lead screw slide and affecting the displacement accuracy, thus ensuring the accuracy of dicing.

[0017] 3. By setting up a first laser sensor and a second laser sensor, it is possible to detect whether the isolation paper or solar cell is being picked up or put down normally, thereby avoiding any impact on the dicing process. Attached Figure Description

[0026] Example:

[0027] refer to Figures 1 to 6A fully automatic dicing machine with paper loading and unloading function includes a base 1. At least two sets of positioning platform assemblies 3 for positioning solar panels are slidably connected in parallel along the Y direction on the base 1, based on a first lead screw slide 2. A laser dicing assembly 5 for dicing solar panels is slidably connected in the X direction on a second lead screw slide 4. The first lead screw slide 2 drives the positioning platform assembly 3 to move to the bottom of the laser dicing assembly 5, thereby dicing the solar panels on the positioning platform assembly 3. At the material loading station of the base 1, release paper collection boxes 6 are fixed in parallel along the X direction for collecting release paper. The base 1 includes a feeding box 7 for feeding solar cells, and a release paper feeding box 8 for providing release paper and a finished product unloading box 9 for collecting solar cells, which are fixedly arranged side-by-side along the X direction at the receiving station of the base 1. At the picking station and receiving station of the base 1, a first adsorption conveying assembly 11 and a second adsorption conveying assembly 12 for conveying release paper and solar cells are synchronously slidably connected based on a third screw slide 10. The first adsorption conveying assembly 11 and the second adsorption conveying assembly 12 are connected based on a connecting seat 15 to achieve synchronous movement on the third screw slide 10. When picking is required... During material handling, the third lead screw sliding assembly drives the first adsorption conveying assembly 11 and the second adsorption conveying assembly 12 to move synchronously. The second adsorption conveying assembly 12 sucks out the solar cell from the feeding box 7 and conveys it to the positioning stage assembly 3 for positioning. At the same time, the first adsorption conveying assembly 11 sucks out the release liner from the feeding box 7 and conveys it to the release liner collection box 6 to complete the release liner collection. After the material handling is completed, the first lead screw slide 2 drives the positioning stage to the dicing station located at the bottom of the laser dicing assembly 5. The second lead screw slide 4 drives the laser dicing assembly 5 to move, thereby positioning and fixing the solar cell on the dicing stage 31. The solar cells are diced. After dicing, the first lead screw slide 2 drives the positioning platform assembly 3 to move to the receiving station. The third lead screw slide 10 located at the receiving station drives the second adsorption conveying assembly 12 to move directly above the positioning platform assembly 3 and adsorbs and conveys the diced solar cells into the finished product unloading box 9. At the same time, the first adsorption conveying assembly 11 takes the release paper out of the release paper supply box 8 and places it between the solar cells. The third lead screw slide 10 drives the first adsorption conveying assembly 11 and the second adsorption conveying assembly 12 to move in coordination, thereby realizing the synchronous conveying and loading of the release paper and the solar cells.

[0028] refer to Figure 2 and Figure 3Specifically, the positioning platform assembly 3 includes a slicing platform 31 for placing solar cells, which is slidably connected along the Y direction to the first lead screw slide 2. A positioning component 32 for positioning adjacent right-angled sides of the solar cell is fixedly connected to the end of the first lead screw slide 2 on the base 1. The positioning component 32 includes a positioning seat 321 fixedly connected to the base 1. A first positioning cylinder 322 for positioning the end face of the solar cell along the X direction and a second positioning cylinder 323 for positioning the side face of the solar cell along the Y direction are fixedly connected to the positioning seat 321. A first positioning block 324 and a second positioning block 325 are fixedly connected to the telescopic ends of the first positioning cylinder 322 and the second positioning cylinder 323, respectively. The positioning block 325 and the first positioning block 324 are fixedly connected with several abutting pulleys 326. When the second adsorption and conveying component 12 drives the solar cell to move onto the slicing stage 31, the first positioning cylinder 322 first drives the first positioning block 324 and the abutting pulleys 326 to abut against the end face of the solar cell. Then the second positioning cylinder 323 drives the second positioning block 325 to abut against the side of the solar cell. The solar cell slides on the abutting pulleys 326 to achieve the positioning of the solar cell. The first laser sensor 33 is fixedly connected to the first lead screw positioning seat 321 to detect whether the solar cell is normally adsorbed onto the slicing stage 31, so as to avoid damage to the slicing stage 31 by the laser scribing component 5. A plurality of adsorption holes 34 are evenly provided on the slicing stage 31 for absorbing dust and impurities generated during the slicing process. An adsorption pipe 35 connected to the adsorption holes 34 is fixedly connected to the slicing stage 31 along the Y direction. A negative pressure absorption pump is connected to the adsorption pipe 35. The dust generated during cutting is adsorbed and discharged through the adsorption pipe 35 and the adsorption holes 34, which reduces air pollution and also prevents dust from entering the lead screw slide and affecting the displacement accuracy, thus ensuring the accuracy of dicing.

The lifting component 14 includes a lifting screw slide 141 fixedly connected to the base 1 in the vertical direction and a sliding end fixedly connected to the lifting screw slide 141 for extending into the hopper 13. The lifting screw slide 141 drives the lifting support 142 to move up and down, thereby ensuring that the top surface of the materials in the feeding box 7, the separator paper supply box 8, and the finished product unloading box 9 remains unchanged to facilitate the release or retrieval of materials.

[0030] refer to Figure 1 and Figure 4 Specifically, the hopper 13 includes a hopper seat 131 horizontally fixedly connected to the base 1, and first abutment blocks 132 symmetrically fixedly connected to the hopper seat 131 at both ends along the Y direction for abutting against the end faces of the positioning release paper or solar cell. Several second abutment blocks 134 are symmetrically slidably connected to both sides of the hopper seat 131 along the X direction based on the sliding groove 133 for abutting against the two sides of the positioning release paper or solar cell. The first abutment blocks 132 and the second abutment blocks 134 are used to position the sides and end faces of the release paper or solar cell. At the same time, by adjusting the position of the first abutment blocks 132 and the second abutment blocks 134 in the hopper seat 131, the positioning requirements of release paper or solar cell of different specifications can be met. The end of the second abutment block 134 away from the hopper seat 131 is flared to facilitate feeding or unloading.

A mounting base 113 is fixedly connected to the telescopic end of the pick-and-place cylinder 112. The first adsorption conveying assembly 11 has several vacuum nozzles 114 evenly distributed on the mounting base 113. The second adsorption conveying assembly 12 has a solar cell adsorption head 121 fixedly connected to the mounting base 113 for adsorbing solar cells. When it is necessary to... When feeding or discharging materials, the feeding cylinder 112 drives the mounting base 113, the vacuum nozzle 114 fixed on the mounting base 113, and the battery cell adsorption head 121 to rise and fall. The feeding or discharging of materials is achieved by controlling the vacuuming or releasing of the vacuum. A second laser sensor 115 is fixedly connected to the mounting base 113 to detect whether the solar cells or the insulating paper are being fed or discharged normally. A pressure sensor 122 is fixedly connected between the mounting base 113 and the feeding cylinder 112 to detect the downward pressure and avoid damage to the solar cells.

[0032] Brief description of the usage process: When material needs to be picked up, the third lead screw sliding assembly drives the first adsorption conveying assembly 11 and the second adsorption conveying assembly 12 to move synchronously. The second adsorption conveying assembly 12 sucks out the solar cell from the feeding box 7 and conveys it to the positioning platform assembly 3 for positioning. At the same time, the first adsorption conveying assembly 11 sucks out the release paper from the feeding box 7 and conveys it to the release paper collection box 6 to complete the collection of the release paper. After the material is picked up, the first lead screw slide 2 drives the positioning platform to the dicing station located at the bottom of the laser dicing assembly 5.

After dicing, the first lead screw slide 2 drives the positioning platform assembly 3 to move to the receiving station. The third lead screw slide 10 located at the receiving station drives the second adsorption conveying assembly 12 to move directly above the positioning platform assembly 3 and adsorbs and conveys the diced solar cells into the finished product unloading box 9. At the same time, the first adsorption conveying assembly 11 takes the release paper out of the release paper supply box 8 and places it between the solar cells.
