Description

Technical Field

[0001] This utility model relates to the field of solder paste printing machine technology, specifically to a feeding mechanism for a roll-to-roll LED strip solder paste printing machine. Background Technology

[0002] A solder paste printer is a device that prints solder paste onto the pads of rigid or flexible circuit boards. Its core objective is to form a uniform and consistent layer of solder paste at the soldering locations of electronic components, ensuring a reliable electrical connection after component mounting and reflow soldering. In the production of LED strips, various electronic components, such as small LED chips or control ICs, typically need to be soldered onto the circuit board; therefore, solder paste printers are also used in the manufacturing process of LED strips.

[0003] Traditional solder paste printers can only meet the solder paste printing needs of fixed-length LED strips and cannot be used for printing solder paste on infinitely long roll LED strips. Current technology typically employs a semi-automatic processing method when processing infinitely long roll LED strips, requiring manual feeding from one side of the printer, resulting in low processing efficiency. To achieve automated processing, it is necessary to design a device capable of automatic feeding. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a feeding mechanism for a roll LED strip solder paste printing machine is disclosed. The solder paste printing machine includes a machine base 1. One side of the machine base 1 is equipped with an unwinding mechanism, and the other side with a receiving mechanism. The unwinding mechanism is used to place and output the roll LED strip to be processed, and the receiving mechanism is used to collect the processed roll LED strip. The machine base 1 is equipped with a mounting plate 2, which is equipped with a material pulling frame 3 and a product positioning seat 4. The material pulling frame 3 is equipped with a spreading plate 31 and a pressure roller 32. During processing, the roll LED strip on the unwinding mechanism can be sequentially laid onto the spreading plate 31 and the product positioning seat 4. The pressure roller 32 is used to press the roll LED strip onto the spreading plate 31, so that the roll LED strip can be laid flat on the product positioning seat 4. The product positioning seat 4 is equipped with a negative pressure suction plate 41, which is externally connected to a negative pressure device. The negative pressure suction plate 41 can hold the roll LED strip in place, thereby preventing the roll LED strip from shifting during processing.

[0024] The material pulling frame 3 is equipped with a transverse moving component 5, and a clamping component 6 is provided on the output end of the transverse moving component 5. The clamping component 6 is used to clamp the rolled light strip on the material spreading plate 31, and the transverse moving component 5 is used to drive the clamping component 6 to move laterally. During the processing, the LED strip on the unwinding mechanism is first stretched and laid onto the laying plate 31 and the product positioning seat 4. The LED strip is then held in place by the negative pressure suction plate 41 on the product positioning seat 4. Then, the solder paste printer is controlled to print solder paste on the LED strip on the negative pressure suction plate 41. After the solder paste printer finishes printing solder paste on the LED strip on the product positioning seat 4, the external negative pressure device is controlled to stop the negative pressure suction, causing the negative pressure suction plate 41 to release the LED strip. The LED strip is then held by the clamping component 6, and the lateral movement component 5 drives the clamping component 6 to move laterally, thereby pulling the LED strip laterally so that the next section of LED strip without solder paste is laid onto the negative pressure suction plate 41 on the product positioning seat 4. The LED strip is then released by the clamping component 6, and the lateral movement component 5 drives the clamping component 6 to reset in the opposite direction, completing one round of pulling action. The above process is repeated to achieve a continuous automatic pulling process.

[0025] The feeding mechanism, through the cooperation of the transverse component 5 and the clamping component 6, can pull the roll of LED strip to move laterally on the laying plate 31, thereby stretching and laying the roll of LED strip onto the product positioning seat 4 in sequence, thus achieving the purpose of automatic feeding of solder paste printing machine and meeting the processing needs of infinitely long roll of LED strip; using machines to replace manual operation improves the automation level of the equipment, can greatly improve processing efficiency, and reduce labor costs.

[0026] In this embodiment, there are two material feeding frames 3, which are symmetrically arranged on both sides of the product positioning seat 4. Each material feeding frame 3 is equipped with a transverse moving component 5 and a clamping component 6. By setting two material feeding frames 3, and each material feeding frame 3 is equipped with a transverse moving component 5 and a clamping component 6, the feeding mechanism can meet the processing requirements of feeding materials from either side of the machine base 1, thereby improving the versatility of processing and meeting the processing needs of some specific locations.

[0027] Specifically, the lateral movement component 5 includes a material pulling motor 51, which is fixedly mounted on the material pulling frame 3. A material pulling screw 52 is provided at the output end of the material pulling motor 51, and a material pulling slider 53 is sleeved on the screw 52. The clamping component 6 includes a gripper cylinder 61, which is fixedly connected to the material pulling slider 53. When material pulling is required, the gripper cylinder 61 clamps the rolled light strip, and the material pulling motor 51 drives the screw 52 to rotate. The screw 52 drives the material pulling slider 53 to slide, and the slider 53 pulls the gripper cylinder 61 to move laterally, thereby pulling the rolled light strip laterally on the material spreading plate 31, achieving the purpose of moving the rolled light strip.

[0028] To improve clamping stability, in this embodiment, the material pulling slider 53 is equipped with two gripper cylinders 61, which are symmetrically arranged on both sides of the material spreading plate 31. During processing, the two gripper cylinders 61 simultaneously clamp the rolled light strip, thereby clamping both sides of the rolled light strip, improving the stability of material pulling, reducing the possibility of the rolled light strip being pulled off-center, and improving processing efficiency and stability.

[0029] To limit and guide the movement direction of the material pulling slider 53, two parallel material pulling guide rails 54 are arranged on the material pulling frame 3, and the material pulling slider 53 is slidably engaged with the material pulling guide rails 54 respectively. During the operation of the material pulling motor 51, the rotation of the material pulling screw 52 will drive the material pulling slider 53 to slide on the material pulling guide rails 54. The cooperation between the material pulling slider 53 and the material pulling guide rails 54 limits and guides the sliding direction of the material pulling slider 53, thereby ensuring that the pulling direction is consistent and reducing the problem of the rolled light strip being pulled off-center.

[0030] In the actual processing, because the output direction of the unwinding mechanism of the LED strip cannot be guaranteed to be consistent, the orientation of each LED strip placed on the product positioning seat 4 may have a certain deviation during the pulling process; therefore, the position of the LED strip on the product positioning seat 4 needs to be calibrated before solder paste printing.

[0031] In this embodiment, a calibration mechanism is provided on the machine base 1. The calibration mechanism is used to drive the product positioning seat 4 to rotate and swing. When the solder paste printer detects that the position of the roll material LED strip on the product positioning seat 4 is not aligned with the printing mechanism of the solder paste printer, it will drive the product positioning seat 4 to rotate and swing through the calibration mechanism, thereby adjusting the direction of the roll material LED strip on the product positioning seat 4 until the position of the roll material LED strip on the product positioning seat 4 is aligned with the printing mechanism of the solder paste printer.

[0032] The calibration mechanism includes a lateral calibration component 7 and a longitudinal calibration component 8. The mounting plate 2 is slidably connected to the machine base 1. The lateral calibration component 7 and the longitudinal calibration component 8 are respectively connected to the mounting plate 2. The lateral calibration component 7 can drive the mounting plate 2 to slide laterally on the machine base 1, and the longitudinal calibration component 8 can drive the mounting plate 2 to slide longitudinally on the machine base 1. When the position of the roll LED strip needs to be calibrated, controlling the lateral calibration component 7 or the longitudinal calibration component 8 alone can drive the mounting plate 2 and the product positioning seat 4 to move laterally or longitudinally. If both the lateral calibration component 7 and the longitudinal calibration component 8 are controlled simultaneously, the mounting plate 2 and the product positioning seat 4 can be driven to rotate and swing on the machine base 1 until the roll LED strip on the product positioning seat 4 is aligned with the printing mechanism of the solder paste printer.

[0033] Specifically, the lateral calibration assembly 7 includes a lateral calibration motor 71 connected to the machine base 1. A lateral calibration lead screw 72 is mounted on the output end of the lateral calibration motor 71, and a lateral calibration slider 73 is sleeved on the lateral calibration lead screw 72. The lateral calibration slider 73 is slidably limited and connected to the machine base 1. A longitudinal calibration guide rail 74 is mounted on the mounting plate 2, and a lateral push block 75 is slidably mounted on the longitudinal calibration guide rail 74. The lateral push block 75 is hinged to the lateral calibration slider 73. The longitudinal calibration assembly 8 includes a longitudinal calibration motor 81 connected to the machine base 1. A longitudinal calibration lead screw is mounted on the output end of the longitudinal calibration motor 81, and a longitudinal calibration slider 83 is sleeved on the longitudinal calibration lead screw. The longitudinal calibration slider 83 is slidably limited and connected to the machine base 1. A lateral calibration guide rail 84 is mounted on the mounting plate 2, and a longitudinal push block 85 is slidably mounted on the lateral calibration guide rail 84. The longitudinal push block 85 is hinged to the longitudinal calibration slider 83. When the position of the product positioning seat 4 needs to be calibrated, the mounting plate 2 and the product positioning seat 4 can be driven to move laterally or longitudinally on the machine base 1 by controlling the operation of the horizontal calibration motor 71 or the vertical calibration motor 81 separately; by controlling the operation of the horizontal calibration motor 71 and the vertical calibration motor 81 simultaneously, the horizontal push block 75 can be pushed to slide on the vertical calibration guide rail 74, and the vertical push block 85 will also be pushed to slide on the horizontal calibration guide rail 84, thereby causing the mounting plate 2 and the product positioning seat 4 to rotate and shift until the roll of LED strip on the product positioning seat 4 is aligned with the printing mechanism of the solder paste printer.

[0034] In this embodiment, there are two longitudinal calibration components 8, each connected to the long side of the mounting plate 2; and one lateral calibration component 7, connected to the short side of the mounting plate 2. In other embodiments, the number of lateral calibration components 7 and longitudinal calibration components 8 can be any other number.

[0035] To enable the mounting plate 2 to rotate and shift smoothly on the machine base 1, universal balls 9 are installed at the four corners of the mounting plate 2. Wear-resistant bases 10 are respectively provided on the machine base 1 at corresponding positions of the universal balls 9, and the universal balls 9 slide against their respective wear-resistant bases 10. When the transverse calibration motor 71 and / or the longitudinal calibration motor 81 are operating, the universal balls 9 slide on the wear-resistant bases 10. Through the cooperation between the universal balls 9 and the wear-resistant bases 10, the mounting plate 2 can rotate and shift smoothly, improving the stability of the transmission and the accuracy of the control.

[0036] Working principle:

[0037] During the processing, the LED strip on the unwinding mechanism is first stretched and laid onto the laying plate 31 and the product positioning seat 4. The LED strip is then held in place by the negative pressure suction plate 41 on the product positioning seat 4. Then, the transverse calibration component 7 and / or the longitudinal calibration component 8 are controlled to work, driving the mounting plate 2 and the product positioning seat 4 to rotate and shift until the LED strip on the product positioning seat 4 is aligned with the printing mechanism of the solder paste printer. Then, the solder paste printer is controlled to print solder paste on the LED strip on the negative pressure suction plate 41. After the solder paste printer finishes printing solder paste on the LED strip on the product positioning seat 4, it controls the negative pressure suction plate 41 on the product positioning seat 4 to release the LED strip. Then, the LED strip is clamped by the clamping component 6, and the clamping component 6 is driven to move laterally by the transverse component 5, thereby pulling the LED strip laterally so that the next section of LED strip without solder paste is laid on the negative pressure suction plate 41 on the product positioning seat 4. Then, the LED strip is released by the clamping component 6, and the clamping component 6 is driven to reset in the opposite direction by the transverse component 5, completing one round of pulling action; repeat the above process to realize the continuous automatic pulling process.

[0038] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
