Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a production fixture for a chip welding reflow tray. Background Art

[0002] Semiconductor lasers are widely used in medical, display, pumping, industrial processing and other fields due to their small size, light weight, high conversion efficiency and long service life. In order to obtain high power output, chip reflow soldering is crucial. Chip reflow soldering is a key process in the production of products by manufacturers. Reflow soldering fixes the chip in the product.

[0003] In the prior art, in the reflow soldering process, a conventional chip is generally fixed on a gold-plated metal part using a reflow soldering fixture, and then reflow soldering is performed. The existing reflow soldering fixture generally uses a screw pressure block to fix the laser chip.

[0004] However, it is difficult to control the pressure of the screws on the chip when fixing with a screw pressure block, which can easily lead to uneven force on the chip when fixing, resulting in damage to the chip. At the same time, the disassembly and installation using the above-mentioned reinforcement method is time-consuming and labor-intensive, thereby reducing processing production efficiency. Utility Model Content

[0005] The utility model aims to provide a chip soldering reflow tray production fixture to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chip soldering reflow tray production fixture, including a tray plate, a limiting groove is provided on the upper surface of the tray plate, an air outlet duct is provided on one side of the limiting groove, and a cold air blower is installed on one side of the air outlet duct.

[0007] An electric cylinder is arranged opposite to the air cooler, a connecting rod is arranged at the lower side of the output end of the electric cylinder, a turntable is arranged at one end of the connecting rod, a slide bar is arranged at the upper side of the turntable, a locking rod is installed at the upper side of the slide bar, and an anti-slip head is fixedly connected to one end of the locking rod

[0012] Preferably, the turntable is rotatably sleeved on a limit rod, one end of the limit rod is fixedly connected to the lower surface of the pallet plate, a guide rod is fixedly connected to the upper surface of the turntable, a slide bar is slidably installed in the pallet plate, a limit plate is arranged on the lower side of the slide bar, and the limit plate is fixedly connected to the pallet plate.

[0013] Preferably, a through hole is opened on the surface of the slide bar, the guide rod is slidably connected to the through hole, fixed columns are fixedly connected to both ends of the upper surface of the slide bar, the fixed columns and the locking rod are slidably connected through an arc groove, the locking rod is rotatably sleeved on the pin shaft, and the lower surface of the pin shaft is fixedly connected to the tray plate.

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

[0015] 1. Fix the elbow and the air outlet pipe of the air cooler in advance through the connection of pipelines, send out cold air through the air cooler, and the cold air generated by the air cooler enters the inside of the elbow and is discharged through the air duct. The discharged cold air flows on the surface of the chip. Start the air cooler before welding, and clean the surface of the chip through the cold air discharged through the air duct. During welding, the cold air flows on the surface of the chip to cool the chip.

[0016] 2. The output end of the electric cylinder extends outward, and is slidably connected with the sliding hole and the sliding rod, so that the sliding rod drives one end of the connecting rod to move, and the other end of the connecting rod is fixedly connected to the turntable, thereby driving the turntable to rotate on the limit rod. The upper surface of the turntable is fixedly connected with a guide rod, and the guide rod drives the slide bar to slide on the lower side of the pallet plate through the sliding connection between the through hole. The limit plate limits the slide bar, so that the slide bar drives the fixed column to move, so that the upper end of the fixed column is slidably connected with the arc groove, and then drives the locking rod to move. The locking rod is rotatably sleeved on the pin shaft, so that the locking rod is fixedly installed to prevent the locking rod from sliding. One end of the slider rotates toward the inside of the limit groove, so that the anti-slip head is in contact with the side wall of the chip board. There are multiple groups of anti-slip heads, so that the anti-slip heads in all directions can abut against the side wall of the chip board, thereby fixing the chip board in the limit groove. When it needs to be removed, the electric cylinder can be retracted, thereby avoiding the method of fixing with a screw pressure block, which makes it difficult to control the pressure of the screw on the chip, and easily causes uneven force on the chip when fixing, so that the chip will not be damaged. At the same time, the method adopted by the utility model is more time-saving and labor-saving, thereby improving the processing and production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] By starting the electric cylinder 5, the output end of the electric cylinder 5 extends outward, and the sliding connection between the sliding hole 15 and the sliding rod 16 causes the sliding rod 16 to drive one end of the connecting rod 6 to move, and the other end of the connecting rod 6 is fixedly connected to the rotating disk 7, thereby driving the rotating disk 7 to rotate on the limiting rod 17, and the upper surface of the rotating disk 7 is fixedly connected with a guide rod 18, and the guide rod 18 is connected to the through hole 20 through a sliding connection, thereby driving the slide bar 8 to slide on the lower side of the tray plate 1, and the limiting plate 19 limits the slide bar 8, so that the slide bar 8 drives the fixed plate 19 to move.
