Description

Technical Field

[0001] This application relates to the field of solder paste tester technology, specifically to an SPI solder paste online tester that facilitates loading and unloading. Background Technology

[0002] SPI stands for Solder Paste Inspection. It is an automated optical inspection technology used to detect the quality and accuracy of solder paste. In the SMT (Surface Mount Technology) process, solder paste is the adhesive used to connect electronic components to the PCB substrate. SPI equipment uses high-speed, high-precision vision processing technology to check parameters such as the height, volume, area, short circuits, and offset of the solder paste on the PCB to ensure printing quality and thus improve the yield of SMT soldering. A solder paste tester is an SMT inspection device that uses optical principles and triangulation to calculate the height of the solder paste printed on the PCB.

[0003] Currently, some existing solder paste testers require staff to manually take a box of solder paste and place it inside the tester. When testing multiple different specifications of solder paste, this repeated taking and placing can be inconvenient and reduce work efficiency. Utility Model Content

[0004] The purpose of this application is to provide an online SPI solder paste tester that facilitates loading and unloading, thus solving the problems mentioned in the background art.

[0005] This application provides an online SPI solder paste tester for easy loading and unloading, including a base, a mounting bracket connected to the upper end of the base, a tester body mounted on the mounting bracket, a fixed box with openings at both ends connected to the upper end of the base, a through hole near the bottom of the fixed box, a threaded tube rotatably connected to the upper end of the base, a rotating assembly for driving the threaded tube to rotate mounted on the base, a threaded rod threadedly connected inside the threaded tube, one end of the threaded rod passing through the opening of the threaded tube and extending outward and connected to a first pushing block, the first pushing block being located at the opening of the fixed box and matching the through hole, a rack slidably connected to the upper end of the base, a gear fixedly sleeved on the wall of the threaded tube, the rack meshing with the gear, a connecting bracket with an L-shaped cross section connected to one end of the rack, a second pushing block connected to one end of the connecting bracket, and the second pushing block being located below the tester body.

[0006] By adopting the above technical solution, during use, the boxed solder paste to be tested is placed sequentially into the fixed box. Due to gravity, the boxed solder paste will stack sequentially within the fixed box, with the bottom boxed solder paste positioned on top of the base. At this point, the rotating assembly rotates the threaded tube. The rotation of the threaded tube, through the thread action, moves the threaded rod. The movement of the threaded rod drives the first pushing block to move, which in turn pushes the bottom boxed solder paste out of the fixed box through the through-hole. Furthermore, the rotation of the threaded tube drives the gear to rotate, and the rotation of the gear applies force to the rack. When force is applied, the rack is driven by the connecting bracket to move the second push block. When the boxed solder paste moves to the position directly below the tester body, the tester body tests the boxed solder paste. After the test is completed, the first push block is reset through the threaded tube and threaded rod. At this time, the boxed solder paste located above will slide down under the force of gravity. When the second push block is reset, it will push the tested boxed solder paste. This process is repeated. Through the above structure, multiple boxed solder pastes can be automatically loaded and unloaded in sequence without manual loading and unloading, reducing labor, saving time, and thus improving work efficiency.

[0007] Optionally, the rotating assembly includes a motor fixedly mounted on the upper end of the base, and the output end of the motor is connected to a threaded pipe via a coupling.

[0008] By adopting the above technical solution, when the motor is started, the motor will drive the threaded tube to rotate.

[0009] Optionally, the upper end of the base is symmetrically connected with two baffles about the fixing box.

[0010] By adopting the above technical solution, the boxed solder paste is limited to prevent it from deviating from the movement trajectory.

[0011] Optionally, the upper end of the base has a groove, and a slider is slidably connected in the groove, with the upper end of the slider connected to the first push block.

[0012] By adopting the above technical solution, the first pushing block is limited to prevent it from rotating.

[0013] Optionally, a slide rod is fixedly connected to the inner wall of the chute, the slide rod passes through the slider, and the slider is slidably connected to the slide rod.

[0014] By adopting the above technical solution, the slider is prevented from detaching from the groove.

[0015] Optionally, a collection box is connected to one end of the base.

[0016] By adopting the above technical solution, it is convenient to collect the boxed solder paste after testing.

[0017] Optionally, a cushioning pad is installed inside the collection box.

[0018] By adopting the above technical solution, the impact force generated when boxed solder paste falls off can be reduced.

[0019] Optionally, a limiting rod is connected to the upper end of the base, the limiting rod passes through the connecting frame, and the connecting frame is slidably connected to the limiting rod.

[0020] By adopting the above technical solutions, the stability of the connecting frame during movement is improved.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application, through the cooperation of structures such as a base, mounting bracket, tester body, fixing box, threaded tube, threaded rod, first push block, rack, gear, connecting bracket, second push block and motor, can automatically load and unload multiple boxed solder pastes sequentially without the need for manual loading and unloading, thereby reducing labor, saving time and improving work efficiency.

[0028] Please see Figure 1-3This application provides a technical solution: an online SPI solder paste tester that facilitates loading and unloading, including a base 1, a mounting bracket 2 connected to the upper end of the base 1, a tester body 3 mounted on the mounting bracket 2, a fixed box 4 with openings at both ends connected to the upper end of the base 1, a through hole near the bottom of the fixed box 4, a threaded tube 5 rotatably connected to the upper end of the base 1, a rotating component for driving the threaded tube 5 to rotate mounted on the base 1, a threaded rod 6 internally threaded to the threaded tube 5, one end of the threaded rod 6 passing through the opening of the threaded tube 5 and extending outward and connected to a first pushing block 7, the first pushing block 7 being located at the opening of the fixed box 4 and matching the through hole, a rack 8 slidably connected to the upper end of the base 1, a gear 9 fixedly sleeved on the wall of the threaded tube 5, the rack 8 meshing with the gear 9, a connecting bracket 10 with an L-shaped cross section connected to one end of the rack 8, a second pushing block 11 connected to one end of the connecting bracket 10, and the second pushing block 11 being located below the tester body 3.

[0029] In the technical solution of this application, during use, the boxed solder paste to be tested is placed sequentially into the fixed box 4. Due to gravity, the boxed solder paste will stack sequentially in the fixed box 4, with the bottom boxed solder paste positioned on top of the base 1. At this time, the threaded tube 5 is rotated by the rotating component. The rotation of the threaded tube 5 causes the threaded rod 6 to move through the thread. The movement of the threaded rod 6 drives the first pushing block 7 to move, which in turn pushes the bottom boxed solder paste in the fixed box 4. The boxed solder paste is then pushed out of the fixed box 4 through the through hole. Furthermore, the rotation of the threaded tube 5 drives the gear 9 to rotate, and the rotation of the gear 9 applies force to the rack 8. When a force is applied, the rack 8, under the influence of the force, will drive the second push block 11 to move through the connecting frame 10. When the boxed solder paste moves to the position directly below the tester body 3, the tester body 3 will test the boxed solder paste. After the test is completed, the first push block 7 will be reset through the threaded tube 5 and the threaded rod 6. At this time, the boxed solder paste located above will slide down under the force of gravity. When the second push block 11 is reset, it will push the boxed solder paste that has been tested. This process is repeated. Through the above structure, multiple boxed solder pastes can be automatically loaded and unloaded in sequence without manual loading and unloading, reducing manual labor, saving time, and thus improving work efficiency.

[0030] In the technical solution of this application, the rotating component includes a motor 12 fixedly installed on the upper end of the base 1. The output end of the motor 12 is connected to the threaded tube 5 through a coupling. When the motor 12 is started, the motor 12 will drive the threaded tube 5 to rotate.

[0031] In the technical solution of this application, two baffles 13 are symmetrically connected to the upper end of the base 1 about the fixing box 4 to limit the boxed solder paste and prevent the boxed solder paste from leaving the movement trajectory.

[0032] In the technical solution of this application, the upper end of the base 1 has a groove, and a slider 14 is slidably connected in the groove. The upper end of the slider 14 is connected to the first push block 7 to limit the first push block 7 and prevent the first push block 7 from rotating.

[0033] In the technical solution of this application, a slide rod 15 is fixedly connected to the inner wall of the chute, the slide rod 15 passes through the slider 14, and the slider 14 is slidably connected to the slide rod 15 to prevent the slider 14 from detaching from the chute.

[0034] In the technical solution of this application, a collection box 16 is connected to one end of the base 1 to facilitate the collection of the boxed solder paste after testing.

[0035] In the technical solution of this application, a buffer pad 17 is installed inside the collection box 16 to reduce the impact force generated when the boxed solder paste falls.

[0036] In the technical solution of this application, a limiting rod 18 is connected to the upper end of the base 1. The limiting rod 18 passes through the connecting frame 10 and is slidably connected to the limiting rod 18, thereby improving the stability of the connecting frame 10 during movement.

[0037] In use, the boxed solder paste to be tested is placed into the fixing box 4 in sequence. Due to gravity, the boxed solder paste will stack in the fixing box 4, with the bottom boxed solder paste positioned on top of the base 1. At this time, the motor 12 rotates the threaded tube 5. The rotation of the threaded tube 5 causes the threaded rod 6 to move through the threaded action. The movement of the threaded rod 6 drives the first push block 7 to move, which in turn pushes the bottom boxed solder paste in the fixing box 4. The boxed solder paste is then pushed out of the fixing box 4 through the through hole. Furthermore, the rotation of the threaded tube 5... The rotation of gear 9 will cause gear 9 to rotate, and the rotation of gear 9 will apply a force to rack 8. The rack 8, under the force, will drive the second push block 11 to move through the connecting frame 10. When the boxed solder paste moves to the position directly below the tester body 3, the tester body 3 will test the boxed solder paste. After the test is completed, the first push block 7 will be reset through the threaded tube 5 and the threaded rod 6. At this time, the boxed solder paste located above will slide down under the force of gravity. When the second push block 11 is reset, it will push the boxed solder paste that has been tested. This process is repeated.
