[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example 1:

[0020] like Figures 1 to 13As shown, an SMT (Surface Mount Technology) component inspection device includes a workbench 11 and a protective housing 111 disposed above the workbench 11. An inspection component 121 is disposed inside the protective housing 111, and an inspection display screen 12 is disposed above the protective housing 111. A mounting housing 1 is disposed at the bottom of the workbench 11. A front L-shaped mounting plate 22 and a rear L-shaped mounting plate 221 are disposed inside the workbench 11. The front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 are symmetrical to each other, and an SMT component body 3 is placed on the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221. A cavity is formed inside the workbench 11, and a slot is formed above the cavity. A T-shaped block 6 is disposed inside the slot. A placement housing 7 is also disposed through the workbench 11. A rectangular slot 71 is formed on the placement housing 7. A drive rail 721 is slidably disposed on the opposite side wall of the inner cavity of the rectangular slot 71, and a drive block 72 is disposed on the opposite side wall of the two drive rails 721. Efficient testing is achieved through the testing component 121, and the testing results are fed back to the testing display screen 12 in real time. The T-shaped block 6 in the workbench 11 can assist the installation wheels in lifting the tested SMT component body 3 after testing, making it convenient for staff to quickly remove it and simplifying the operation process. The rectangular slot 71, drive rail 721 and drive block 72 on the housing 7 are linked together, and when reset, they can drive the remaining SMT component bodies 3 to automatically move to the testing position, improving the continuity and efficiency of testing.

[0021] like Figures 1 to 9 As shown, in a specific embodiment, electric slide rails 2 are provided on both opposite side walls of the inner cavity of the protective housing 111. The two electric slide rails 2 are symmetrical to each other. C-shaped mounting plates 201 are slidably provided on the opposite side wall of the two electric slide rails 2. Front mounting sliders 21 and rear mounting sliders 211 are slidably provided on the opposite side wall of the two C-shaped mounting plates 201. Each front mounting slider 21 and rear mounting slider 211 is symmetrical to each other. Each front mounting slider 21 and rear mounting slider 211 has a fixing spring 212 at one opposite end. The other end of each fixing spring 212 is respectively provided on the C-shaped mounting plate 201. A front L-shaped mounting plate 22 is provided at one opposite end of the two front mounting sliders 21, and a rear L-shaped mounting plate 221 is provided at one opposite end of the two rear mounting sliders 211. In this setup, a sliding guide assembly is formed by symmetrically arranged electric slide rails 2, front mounting sliders 21, and rear mounting sliders 211, which can drive the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 to move smoothly, so as to enable the SMT placement body 3 to accurately enter and exit the internal detection area of ​​the protective housing 111.

[0022] like Figures 1 to 9As shown, furthermore, both the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 are provided with lower moving grooves 222, and each pair of lower moving grooves 222 is symmetrical to each other. A movable loop cylinder 24 is provided on each of the opposite side walls above the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221. A movable insertion plate 241 is slidably mounted inside the two movable loop cylinders 24. An upper moving slider 243 is provided at the bottom of each of the two movable loop cylinders 24, and the two upper moving sliders 243 are symmetrical to each other. The other ends of the two upper moving sliders 243 are slidably mounted inside the lower moving grooves 222. In this configuration, the lower moving grooves 222 and the upper moving sliders 243 form a double-track limiting sliding structure, allowing the movable insertion plate 241 to slide directionally along the inner cavity of the movable loop cylinder 24, ensuring smooth and unobstructed movement when subsequently pushing the SMT component body 3.

[0023] like Figures 1 to 9 As shown, furthermore, a fixed U-shaped cylinder 23 is provided at one end of the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 away from the movable plug-in plate 241. The two fixed U-shaped cylinders 23 are symmetrical to each other, and a fixed plug-in plate 231 is slidably disposed inside the two fixed U-shaped cylinders 23. Multiple SMT chip bodies 3 are placed on the opposite side wall of the fixed plug-in plate 231 and the movable plug-in plate 241. In this configuration, the fixed plug-in plate 231 can slide along the fixed U-shaped cylinder 23 to limit its movement, and cooperate with the movable plug-in plate 241 to form a clamping and positioning range, which can regulate and limit the linearly arranged SMT chip bodies 3, and prevent the chips from shifting or misaligning during the transfer and inspection process.

[0024] like Figures 1 to 10 As shown, furthermore, a fixed housing 56 is provided at the bottom of the opposite side wall of the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221. Mounting wheels 561 are rotatably mounted inside the fixed housing 56, and the two mounting wheels 561 are symmetrical to each other. A right roller 5 and a left roller 51 are respectively provided at both ends of the fixed housing 56. Rotating rods 522 are respectively provided at opposite ends of the right roller 5 and the left roller 51, and the two rotating rods 522 are symmetrical to each other. Precision deep groove ball bearings 521 are provided at opposite ends of the two precision deep groove ball bearings 521. A drive block 52 is provided at opposite ends of the two precision deep groove ball bearings 521. In this configuration, the mounting wheels 561 can rotate flexibly within the fixed housing 56. The right roller 5 and the left roller 51 achieve power transfer through the rotating rods 522 and the precision deep groove ball bearings 521, converting the lifting stroke of the rollers into the mechanical power of the drive block 52, thus completing the linkage transmission of the entire machine structure.

[0025] like Figures 1 to 10As shown, furthermore, two swing arms 53 are movably arranged on both sides of the drive block 52. The two swing arms 53 are symmetrical to each other, and the ends of the two swing arms 53 away from the drive block 52 are respectively set on the front mounting slider 21 and the rear mounting slider 211. A movable rod 54 is also movably arranged on the drive block 52, and a push plate 55 is movably arranged on the other end of the movable rod 54. The other end of the push plate 55 is set on the movable plug-in plate 241. In this configuration, the drive block 52 realizes the fine-tuning and alignment of the mounting plate through the linkage of the swing arms 53 with the front mounting slider 211 and the rear mounting slider 211. At the same time, relying on the push-pull transmission mechanism formed by the movable rod 54 and the push plate 55, it can accurately drive the movable plug-in plate 241 to move, and complete the automatic replenishment and feeding of the remaining SMT placement body 3. Example 2:

[0026] The difference between the above embodiments and this embodiment is that: Figures 1 to 13 As shown, an SMT (Surface Mount Technology) component inspection device includes a housing 7 with a wedge-shaped block 731 positioned within a rectangular slot 71. An L-shaped movable plate 73 is located at the bottom of the wedge-shaped block 731 and movably extends through the housing 7. A connecting plate 8 is also mounted on the L-shaped movable plate 73, and a magnet 92 is located at its bottom. A placement slot 81 is provided on the connecting plate 8. The wedge-shaped block 731 acts as a force transmission intermediary, receiving the squeezing force of the driving block 72 and causing the L-shaped movable plate 73 to slide directionally along the housing 7. The connecting plate 8 provides movement space for the flip plate 83 through the placement slot 81. The magnet 92, in conjunction with a subsequent electromagnet 91, achieves positioning and locking, forming a linkage triggering structure for the inspection station.

[0027] like Figures 1 to 13 As shown in the specific embodiment, two positioning plates 82 are also provided at the bottom of the inner cavity of the workbench 11. The two positioning plates 82 are symmetrical to each other, and a fixed bearing 821 is provided at the opposite end of each positioning plate 82. The two fixed bearings 821 are symmetrical to each other, and a rotating rod 822 is provided on the two fixed bearings 821. A flipping plate 83 is provided at the opposite end of the two rotating rods 822. The flipping plate 83 is movably inserted through the placement slot 81 opened on the connecting plate 8, and the two ends of the flipping plate 83 are respectively attached to the T-shaped block 6 and the connecting plate 8. In this configuration, the positioning plates 82 provide rotational support for the flipping plate 83 through the fixed bearings 821 and the rotating rods 822. The flipping plate 83 is movably connected to the connecting plate 8 through the placement slot 81. Under the drive of the L-shaped moving plate 73, it can be flipped around the rotating rod 822, thereby pushing the T-shaped block 6 to move vertically upward, providing structural support for the subsequent lifting of the mounting wheel 561 and the upward movement of the patch for material picking.

[0028] like Figures 1 to 13As shown, furthermore, a positioning housing 9 is provided at the bottom of the inner cavity of the workbench 11. An electromagnet 91 is placed inside the positioning housing 9, and the electromagnet 91 and the magnet 92 attract each other. In this configuration, the positioning housing 9 serves to fix and limit the electromagnet 91. After the electromagnet 91 is energized, it generates an attraction force with the magnet 92 at the bottom of the L-shaped moving plate 73, which can lock the positions of the L-shaped moving plate 73, the flip plate 83, and the T-shaped block 6, avoiding the detection deviation of the SMT placement body 3 due to structural displacement during the detection process, and ensuring the stability of the detection station. Example 3:

[0029] This invention also discloses an SMT chip inspection method, the steps of which are as follows: Step 1: Place the single-specification SMT chip body 3 between the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 in sequence, and attach and fix the opposite side walls of the plug plate 231 and the movable plug plate 241 to complete the chip loading and positioning in a linear distribution. Step 2: Control the operation of the electric slide rail 2, drive the front mounting slider 21 and the rear mounting slider 211 to move the mounting plate and patch into the protective housing 111, the rear L-shaped mounting plate 221 squeezes the driving block 72, and the L-shaped moving plate 73 and the flipping plate 83 push the T-shaped block 6 upward, and the electromagnet 91 and the magnet 92 are attracted and fixed. Step 3: Start the detection component 121 to detect the SMT patch body 3 inside the protective housing 111. The detection data is synchronized to the detection display screen 12 in real time, and the staff can observe the detection status and results in real time. Step 4: After the test is completed, the control plate is reset, the mounting wheel 561 moves to the T-block 6 and is lifted, which drives the tested SMT chip body 3 to move upward, and the staff takes out the batch of chips. Step 5: The right roller 5 and the left roller 51 move with the mounting plate to the T-shaped block 6. The drive block 52, through the linkage of the swing arm 53 and the movable rod 54, drives the movable plug plate 241 to move horizontally, pushing the remaining patch to the inspection station, ready for the next round of inspection.

[0030] The implementation principle of the SMT chip inspection equipment of the present invention is as follows: The staff neatly arranges the single-specification SMT chip body 3 between the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 to meet the material feeding requirements of large-scale continuous production. After placement, the operator controls the electric slide rail 2 to move, which in turn moves the C-shaped mounting plate 201 horizontally. When the C-shaped mounting plate 201 moves, it moves the front mounting slider 21 and the rear mounting slider 211 together, which in turn moves the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221. This allows the SMT component 3 to enter the inner cavity of the protective housing 111. At this time, the operator controls the detection component 121 to detect the placed SMT component 3. The specific detection method is the existing technical solution (where the SMT component 3 being detected is the SMT component 3 parallel to the placement housing 7).

[0031] When the rear L-shaped mounting plate 221 moves, it can squeeze the driving block 72, which, with the assistance of the driving track 721, can move into the inner cavity of the rectangular slot 71. Therefore, the driving block 72 can squeeze the inclined surface of the wedge block 731, thereby driving the L-shaped moving plate 73 to move downward. When the L-shaped moving plate 73 moves downward, it can drive the connecting plate 8 to move downward. Therefore, the connecting plate 8 can press the flipping plate 83 to rotate with the assistance of the rotating rod 822 and the fixed bearing 821 (where the fixed bearing 821 is a precision bearing to ensure rotation accuracy). When the flipping plate 83 flips, its other end can push the T-shaped block 6 to move vertically upward, thereby moving it above the worktable 11. At the same time, when the L-shaped moving plate 73 moves downward, it can also move downward with the assistance of the magnet 92. At this time, the operator controls the electromagnet 91 to run, so that the electromagnet 91 and the magnet 92 can attract each other, thus ensuring that the T-shaped block 6 is positioned to a certain extent. After the SMT component body 3 has been inspected, the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 are reset. During the reset, the mounting wheels 561 at the bottom of the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 move onto the T-shaped block 6. Then, the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 continue to move, allowing the mounting wheels 561 to be lifted with the assistance of the T-shaped block 6. When the mounting wheels 561 are lifted, they can move the inspected SMT component body 3 upwards, making it easier for the operator to remove the inspected SMT component body 3 (here, the inspected SMT component body 3 refers to the SMT component body 3 placement station that is always opposite to the placement housing 7). When the SMT placement body 3 moves upward to the horizontal plane of the T-block 6, the right roller 5 and the left roller 51 will move onto the T-block 6, thus enabling them to move upward with the assistance of the T-block 6. When the right roller 5 and the left roller 51 move upward, they can drive the drive block 52 to move upward. Therefore, the swing arm 53 on the drive block 52 can drive the front mounting slider 21 and the rear mounting slider 211 to move to both sides with the assistance of the electric slide rail 2 (thus ensuring that the remaining SMT placement bodies 3 can move). At the same time, when the drive block 52 moves upward, it can also drive the movable rod 54 to drive the push. The movable plate 55 drives the movable plug-in plate 241 to move horizontally with the assistance of the movable swivel cylinder 24 (which is made of wear-resistant alloy material), the lower movable slide 222, and the upper movable slider 243 (because the movable swivel cylinder 24 is respectively set on the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221, and the movable plug-in rod 241 is movably inserted into the inner cavity of the movable swivel cylinder 24). This allows the movable plug-in plate 241 to drive the remaining SMT component bodies 3 placed on the front L-shaped mounting plate 22 and the rear L-shaped mounting plate 221 to move to the previously inspected SMT component body 3, thus facilitating the next inspection.

[0032] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
