[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 As shown in this embodiment, a silicon wafer and adhesive strip assembly mechanism for a BC battery string bonding machine includes an adhesive strip cutting structure and a melt conveying structure. The adhesive strip cutting structure includes an adhesive strip cutting bracket 1, an adhesive strip clamp 2, and an adhesive strip cutter 3. An adhesive strip transverse moving module 4 is installed on the adhesive strip cutting bracket 1 along the left-right direction. The adhesive strip clamp 2 and the adhesive strip cutter 3 are both connected to the drive end of the adhesive strip transverse moving module 4. The melt conveying structure includes a melt adhesive adhesion bracket 5 and a melt platform 6. The melt adhesive adhesion bracket 5 is provided with two sets of melt front and rear modules along the front and rear direction. A melt vertical moving slide rail is provided on the drive end of each set of melt front and rear modules. A melt vertical moving slider 7 is connected below the melt platform 6. The melt vertical moving slider 7 slides on the melt vertical moving slide rail. A melt heating tube 8 is inserted inside the melt platform 6.

[0024] The adhesive strip clamp 2 clamps the front end of the adhesive strip and pulls it out above the melting platform 6. With the adhesive strip cutter 3 clamping the rear end of the adhesive strip first, it is smoothly lowered. Then the adhesive strip cutter 3 cuts the adhesive strip. Then the adhesive strip cutter 3 retracts, freeing up the cut-off part of the adhesive strip. The adhesive strip clamp 2 then comes over to clamp the cut-off part and pulls it out. The above operation is repeated.

[0025] After the adhesive strip is placed at the correct position on the melting platform 6, the front and rear melting modules control the positions of the two sides of the melting platform 6 to interchange. When they meet in the middle, the vertical sliding rail and the vertical sliding slider 7 make the height of the two sets of melting platforms 6 different to prevent collision. The melting platform 6 with the adhesive strip moves backward to connect with half of the silicon wafer, so that there is an adhesive strip in the gap between the half of the silicon wafer. After the melting heating tube 8 heats up, the hot melt adhesive strip adheres the silicon wafer together.

[0026] One end of the rubber strip cutting bracket 1 is rotatably connected to the rubber strip feeding tray 9. The incoming rubber strip is wound on the rubber strip feeding tray 9, and the end is stretched out for segmented cutting.

[0027] The drive end of the adhesive strip transverse module 4 is equipped with an adhesive strip pull plate 10 and an adhesive strip cutter plate 11. The lower end of the adhesive strip pull plate 10 is equipped with an adhesive strip front cylinder 12 and an adhesive strip front clamp 13. The drive end of the adhesive strip front cylinder 12 is hinged to the adhesive strip chuck 2. The adhesive strip chuck 2 and the adhesive strip front clamp 13 clamp the front end of the adhesive strip. The lower end of the adhesive strip cutter plate 11 is equipped with an adhesive strip rear cylinder 14, an adhesive strip cutting cylinder 15, and an adhesive strip rear clamp 16. The adhesive strip cutter 3 is mounted on the drive end of the adhesive strip cutting cylinder 15. The drive end of the rear cylinder 14 clamps the rear end of the rubber strip with the rear clamp seat 16. The rubber strip transverse module 4 is equipped with a rubber strip transverse motor 17 and a rubber strip transverse slide rail 18. The drive end of the rubber strip transverse motor 17 is connected to a rubber strip transverse synchronous pulley 19. The rubber strip transverse synchronous pulley 19 is connected to a rubber strip transverse synchronous belt 20. The rubber strip pull plate 10 and the rubber strip cutter 11 are respectively fixed on both sides of the rubber strip transverse synchronous belt 20. The rubber strip pull plate 10 and the rubber strip cutter 11 move towards each other or away from each other.

[0028] The adhesive strip lateral movement motor 17 controls the movement of the adhesive strip lateral movement synchronous belt 20. When the adhesive strip pulling plate 10 and the adhesive strip cutting plate 11 approach each other, the adhesive strip front cylinder 12 and the adhesive strip front clamp 13 on the adhesive strip pulling plate 10 clamp and cut one end of the adhesive strip onto the adhesive strip rear cylinder 14 and the adhesive strip rear clamp 16. Then, the adhesive strip pulling plate 10 and the adhesive strip cutting plate 11 separate from each other, and the adhesive strip rear cylinder 14 and the adhesive strip rear clamp 16 release the adhesive strip, so that the adhesive strip is held in place by the adhesive strip front cylinder 12 and the adhesive strip... The front clamp 13 is pulled out to the appropriate position. After the melting platform 6 is lifted, the glue strip can be placed on the melting platform 6. The glue strip cutting cylinder 15 controls the glue strip cutter 3 to move down and cut the glue strip. The front and rear are released, and the melting platform 6 descends to the horizontal height. At this time, the glue strip rear cylinder 14 and the glue strip rear clamp 16 clamp the cut glue strip. The glue strip pulling plate 10 and the glue strip cutting plate 11 move closer to each other again. The above operation is repeated to pull out the glue strip.

[0029] A melting platform 6 has a melting plate 21 fixed at its lower end. A melting vertical motor 22 is installed on the melting plate 21. The melting vertical motor 22 is driven by a melting lifting screw 23. A melting lifting nut is threaded onto the melting lifting screw 23. The melting lifting nut is fixed on the glue strip transverse module 4. Both the lower end of the melting lifting screw 23 and the drive end of the melting vertical motor 22 are equipped with melting lifting synchronous pulleys 24. A melting lifting synchronous belt 25 is driven between the melting lifting synchronous pulleys 24. The melting platform 6 has several platform suction holes 26. A platform air pipe connector 27 is connected to the outside of the melting platform 6. The platform suction holes 26 are connected to the platform air pipe connector 27.

[0030] The two sets of front and rear modules on the molten adhesive adhesion bracket 5 move relative to each other, one in front and one behind, one on the left and one on the right, one high and one low, without causing contact or interference between them. The front and rear movement is controlled by the front and rear modules, the left and right movement is determined by the installation position of the front and rear modules, and the height is controlled by the molten adhesive vertical movement motor 22. The molten adhesive lifting screw 23 rotates, driving the entire molten adhesive stand plate 21 to move up and down along the molten adhesive vertical movement slide rail. When the adhesive strip reaches the molten adhesive platform 6, the negative pressure created by the platform's adsorption hole 26 fixes the position of the half silicon wafer, facilitating the connection of the molten adhesive strip.

[0031] All modules involved in this application are linear modules.

[0032] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
