[0033] Furthermore, the transfer frame 2 includes a U-shaped frame 21, a pusher 22, a linkage 23, and a guide rail 24. The guide rail 24 is fixedly mounted on the two inner walls of the U-shaped frame 21 in a mirror image. The two sets of guide rails 24 are filled with placement boxes 3 laterally. The pusher 22 is installed on the front wall of the U-shaped frame 21. The linkage 23 is provided on the rear side of the left end of the pusher 22. The top of the pusher 22 contacts the bottom side of the placement box 3. The above design is beneficial for filling multiple sets of placement boxes, thereby improving installation efficiency.

[0034] Furthermore, the pusher 22 includes a fixed plate 221, an electric push rod 222, a moving block 223, and a side block 224. The electric push rod 222 is installed on the right end of the fixed plate 221. A starter is provided at the rear end of the electric push rod 222 for starting and stopping. The moving block 223 is fixed on the right end of the electric push rod 222. Two sets of arc-shaped blocks 225 with the same direction are installed on the top of the moving block 223. Side blocks 224 are provided in front and behind each set of arc-shaped blocks 225. The arc-shaped blocks 225 flip within the side blocks 224. The left wall of the arc-shaped blocks 225 is connected to the inclined plate 227 through two sets of first springs 226. The two sets of inclined plates 227 are fixed on the top of the moving block 223. Through the above design, the two sets of arc-shaped blocks and the first springs can be used in conjunction with the contact parts at the bottom end, so as to be compatible with the placement box for use and thus complete the conveying.

[0035] Furthermore, the linkage 23 includes a slide cylinder 231, a slide rod 232, a fixing block 233, and a second spring 234. The slide cylinder 231 is installed on the rear wall of the U-shaped frame 21. The slide rod 232 is installed longitudinally inside the slide cylinder 231.

The two sets of vertical plates 235 are fixed at the bottom of the U-shaped frame 21. The sliding rod and the pusher work together to complete the transfer of the placement box, thereby reducing the manual handling time.

[0036] As a further improvement of the present invention, the placement box 3 is shaped like a U-shaped box 301. Slider 302 is fixedly provided at the front and rear of the U-shaped box 301, and partition plates 303 are fixedly provided on the left and right sides of the U-shaped box 301.

[0038] Furthermore, the clamping component 32 includes a drive motor 321, a threaded rod 322, a threaded cylinder 323, and a connecting rod 324. The front end of the drive motor 321 drives the threaded rod 322 to rotate. The front end of the threaded rod 322 is inserted into the bottom end of the U-shaped box 301. Threaded cylinders 323 are installed on both sides of the center of the threaded rod 322. Both sets of threaded cylinders 323 are installed at the center of the connecting rod 324.

The rear clamping plate 325 and the front clamping plate 326 are clamped relative to each other by the threaded rod 322. The rear clamping plate 325 includes a rear clamping plate 3251 and a connection at the bottom end. The rod 324 and the two ends of the rear clamping plate 3251 slide within the slide rail 305. The front end of the rear clamping plate 3251 has an arc-shaped groove 3252, and both sides of the arc-shaped groove 3252 have strip grooves 3253. The front clamping plate 326 includes a front clamping plate 3261, a semi-circular plate 3262, and strip columns 3263. The semi-circular plate 3262 is fixed at the rear end of the front clamping plate 3261, and strip columns 3263 are fixed on both sides of the rear end of the front clamping plate 3261. The two sets of strip columns 3263 are connected to the strip grooves 3253. The front and rear clamping plates are mirrored and clamped synchronously, thereby adapting to clamping motherboards of different specifications, which is convenient, quick, and accurate in positioning.

[0039] Furthermore, a hydraulic cylinder 41 is installed at the top of the pick-and-place machine 4. The hydraulic cylinder 41 drives the pick-and-place machine 4 to lift and lower. A linkage rod 42 is fixed at the rear end of the pick-and-place machine 4. A lower pressure plate 421 is fixed at the bottom of the rear end of the linkage rod 42. The linkage rod 42 lifts and lowers simultaneously with the pick-and-place machine 4. A beveled surface 422 is opened at the bottom end of the lower pressure plate 421. The angle of the beveled surface can drive the slide rod to move a specified distance, thereby controlling the electric push rod to start and stop.

[0040] Furthermore, the cooling component 5 includes a mounting bracket 51, a fixed bearing 52, a rotating shaft 53, and a turbo fan 54. The mounting bracket 51 is fixed to the right end of the U-shaped frame 21. The fixed bearing 52 is installed at the center of the mounting bracket 51, and the rotating shaft 53 is installed at the center of the fixed bearing 52. The turbo fan 54 is installed at the bottom end of the rotating shaft 53, and the top end of the rotating shaft 53 is driven by a servo motor 55, which facilitates cooling of the motherboard after surface mounting and improves product bonding efficiency.

[0041] Working principle: During operation, when surface mount technology (SMT) is required, the motherboard is first placed in a set of placement boxes 3. When the motherboard is placed on multiple sets of rubber pillars 312 inside the U-shaped box 301, the drive motor 321 is started to drive the threaded rod 322 to rotate. The rotation of the threaded rod 322 drives the two sets of threaded cylinders 323 to move inward synchronously. The movement of the two sets of threaded cylinders 323 drives the two sets of connecting rods 324 to move. The movement of the two sets of connecting rods 324 drives the rear clamps respectively. The plate 3251 and the front clamping plate 3261 move relative to each other to clamp the motherboard. The semi-circular plate 3262 and the strip column 3263 fixed on the front clamping plate 3261 are respectively docked and limited with the rear clamping plate 3251. Then, the placement box 3 for mounting the motherboard is pushed into the guide rail 24 inside the U-shaped frame 21 by the front and rear sliders 302. When multiple sets of placement boxes 3 are docked end to end, when the pick-and-place machine 4 descends by the hydraulic cylinder 41, the rear linkage rod 42 and the lower pressure plate 421 descend, which can drive the slider. When lever 232 moves forward, sliding lever 323 moves forward to contact the starter in electric push rod 222 to activate it. Electric push rod 222 then pushes moving block 223 to the right. Under the action of the first spring 226, the two sets of arc-shaped blocks 225 at the top of moving block 223 push the two sets of contact blocks 304 fixed at the bottom of a set of U-shaped boxes 301 to move. When the U-shaped box 301 moves to the right end position, it is the vertical position of the pick-and-place machine 4. Then the pick-and-place machine 4 continues to descend to place the chip onto the motherboard. After placement, when the pick-and-place machine 4 rises, sliding lever 232 returns to its original position under the action of the second spring 234. When returning to its original position, sliding lever 232 separates from electric push rod 222, and electric push rod 222 returns to its original position to contact the next set of U-shaped boxes 301. Then, the operation of U-shaped boxes 301 can be repeated. When U-shaped box 301 moves to the right, the servo motor 55 drives the rotating shaft 53 to rotate, which drives the turbine fan 54 to rotate and complete the cooling.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
