Description

Technical Field

[0001] The utility model relates to the field of chip placement machines, in particular to a double-track front and rear arm high-speed chip placement machine. Background Art

[0002] Existing placement machines, while technologically mature, lack specificity in placement. This is especially true for situations where small components need to be placed in batches on circuit boards. While general-purpose placement machines can be used for this, they have long travels, multiple nozzle stations, and multiple feeder mounting locations. This creates a waste of time and prevents faster placement, leading to wasted stations and energy, and low production efficiency.

[0003] Although there are multi-station placement machines or single-track dual-head placement machines on the market, when this type of placement machine is used, the production between the two placement heads or the two stations will interfere with each other, which to a certain extent hinders the improvement of the placement speed.

[0048] like Figure 7 As shown, in this embodiment, the driving device includes a flying camera linear track 384, a linear motor and a camera bracket 382, ​​the stator 383 of the linear motor is fixed to the lower part of the rear side surface of the Z-axis fixed base plate 33, and is arranged along the X-axis direction, the flying camera linear track 384 is respectively arranged on the upper and lower sides of the stator 383 of the linear motor, the mover 381 of the linear motor can be moved back and forth on the stator 383, the middle part of the camera bracket 382 is fixedly connected to the mover 381 of the linear motor, and the upper and lower parts of the camera bracket 382 are respectively fixed with sliders, and the sliders can slide along the flying camera linear track 384; the lower end of the camera bracket 382 extends to the bottom of the Z-axis fixed base plate 33, the rear end of the head flying camera assembly 37 is fixedly connected to the lower end of the camera bracket 382, ​​and the front end of the head flying camera assembly 363 extends forward, and its camera lens faces the mounting head suction nozzle 347.

[0049] After the equipment is debugged, the circuit board feed mechanism 6 feeds the circuit board to be mounted from the input end of the workbench 1 to the center of the workbench 1. The incoming material sensor 61 senses the feeding position of the circuit board, and the flying chip placement machine head 3 moves above the circuit board. The telescopic shaft of the stop cylinder 35, driven by the cylinder body, can extend or retract downward to stop the circuit board being fed from the circuit board feed mechanism 6. The circuit board camera 361 then captures and records the circuit board information. Driven by the X-axis motion mechanism 5 and the Y-axis motion mechanism 4, the flying chip placement machine head 3 moves to the flyer board base 7. The multi-station placement head nozzle 347 picks up the electrical components on the flyer and moves it above the circuit board. Simultaneously, the linear motor drives the flying camera assembly 37 to move from left to right along the X-axis direction, capturing and recording the electronic component information on the placement head nozzle 347 during this movement. Based on the recorded electronic component information, the stepper motor 32 within each placement head mechanism 34 drives the placement head nozzle 347 downward, while the corner motor 345 drives the placement head nozzle 347 to rotate, sequentially placing the electronic components on the placement head nozzle 347 at fixed locations on the circuit board. After placement is complete, the flying shot placement machine head 3 moves a second time to the flyer plate base 7 to retrieve the material. After retrieving the material, it moves above the circuit board to prepare for the second placement. Simultaneously, the linear motor drives the flying shot camera assembly 37 from right to left along the X-axis, capturing and recording the electronic component information on the placement head nozzle 347 during this movement. The flying shot camera assembly 363 can move from left to right and then return from right to left for the second retrieval, simultaneously capturing the electronic component information on the placement head nozzle 347. This minimizes the number of movements, simplifying the original three-point docking system, which involves the flyer plate base 7, the high-speed flying shot mechanism, and the top of the circuit board, to a two-point docking system, which involves the flyer plate base 7 and the top of the circuit board, thereby improving flying shot efficiency. According to the electronic component information recorded in these shots, each mounting head mechanism 34 sequentially mounts the electronic components on the mounting head suction nozzle 347 to a fixed position on the circuit board. Repeat the above actions to achieve repeated mounting. The utility model adopts two groups of workstations set up in the front and back for mounting, which shortens the travel distance of the flying mount head 3, and divides the original front and back two feeder plate seats 7 into two groups, each of which is equipped with its own feeder for feeding, which is very suitable for the processing needs of mounting small components on such circuit boards, because in this processing process, the number of repeated mountings is large, but the types of mounted components are relatively fixed, which improves the utilization rate of the feeder plate seat 7 and cooperates with the flying mount head 3 to further improve the mounting speed, meeting the company's processing needs for batch mounting of small components on circuit boards.
