Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a component mounting auxiliary tooling. Background Art

[0002] During the electronic component placement process, component placement auxiliary tooling is required to fix the circuit board to help operators accurately install and fix electronic components on the circuit board.

[0003] Auxiliary tooling for electronic component placement can ensure the accurate position of electronic components during placement, avoid displacement or swinging, and help improve placement accuracy. However, most of them can only perform a single clamping and fixing of the circuit board, and in the case of abnormal clamping force control, it will cause scratches at the clamping point of the circuit board. After the electronic components are placed, automatic loading cannot be performed, and frequent loading is cumbersome. For this reason, we propose a component placement auxiliary tooling to solve the existing problems. Utility Model Content

[0004] The purpose of the utility model is to propose a component mounting auxiliary tooling in view of the problems existing in the background technology.

[0007] Preferably, a gear is provided at the output end of the second motor, a gear ring is sleeved at one end of the rotating shaft, and the gear and the gear ring are meshed with each other. When the second motor rotates, the driving gear pushes the gear ring, so that the rotating shaft drives the installation box to flip.

[0008] Preferably, a protective cover is provided on one side of the rotating bracket, and the motor 2, gear and gear ring are all located inside the protective cover. The protective cover protects the motor 2, gear and gear ring to prevent the shunt pipe from being clamped and damaged when the installation box rotates.

[0009] Preferably, a symmetrically distributed shunt pipe is installed through one end of the installation box, and the shunt pipe is a hose and is spiral-shaped. The spiral shunt pipe has stroke compensation and is effectively used after rotating with the installation box.

[0010] Preferably, a partition is provided inside the installation box, and the diverter pipe runs through the installation box and is located on the upper and lower sides of the partition. The partition divides the internal space of the installation box into two parts, and the suction force transmitted inside the two diverter pipes is distributed to the space inside the upper and lower ends of the installation box.

[0011] Preferably, a bearing is embedded and installed inside the lower end of the mounting frame, the upper end of the screw is rotatably inserted into the bearing, a guide rod is provided at the upper end of the bottom plate, the threaded block is rotatably sleeved on the outer wall of the screw, and the sliding sleeve is slidably sleeved on the outer wall of the guide rod.

[0012] Preferably, both sides of the lower end of the carrier plate are provided with symmetrically distributed weighing sensors connected to the lifting platform at the lower end, and one side of the upper end of the mounting frame is provided with an alarm. The weighing sensor detects the weight on the upper end of the carrier plate, and when the threshold is reached, the signal is transmitted to the terminal, and the terminal controls the alarm to sound an alarm, reminding the staff to replenish the circuit board on the carrier platform.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model uses the suction cup to negatively absorb the lower end of the circuit board, so as to avoid the problem of scratching the circuit board due to clamping. The load-bearing platform can automatically adjust the lifting and lowering, and the installation box can be turned over. The suction cup is used to conveniently carry and load the circuit boards stacked on the load-bearing platform, so that the staff can avoid frequent loading. The loading is convenient. When the electronic components are mounted, the suction cup is also provided at the lower end of the installation box. When the electronic components are mounted on the circuit board at the upper end of the installation box, the circuit board to be processed is pre-absorbed. After the electronic components on the same circuit board are mounted, the circuit board can be quickly replaced, thereby improving the efficiency of electronic component mounting.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 5 As shown, the utility model proposes a component mounting auxiliary tooling, including a shunt pipe 14, a negative pressure pump 3, a mounting frame 4, a bottom plate 6, a lifting platform 8, a mounting box 9 and a motor 22. The upper end of the bottom plate 6 is provided with a symmetrically distributed mounting frame 4, and a mounting box 9 is provided above the mounting frame 4. The upper end of the mounting box 9 is provided with equidistantly distributed suction cups 12, and the mounting boxes 9 are all provided with a rotating shaft 25. The upper end of the mounting frame 4 is provided with a negative pressure pump 3, and the suction end of the negative pressure pump 3 is provided with a suction pipe 2. A shunt tube 1 is installed at one end of the suction pipe 2, and a symmetrically distributed shunt pipe 14 is installed at one end of the mounting box 9. The shunt pipe 14 is a hose and is spiral. The mounting box 9 is provided with a partition 26 inside, the shunt pipe 14 runs through the inside of the installation box 9 and is located on the upper and lower sides of the partition 26, a motor 7 is provided at the upper end of the bottom plate 6, a screw 16 is provided at the upper end of the motor 7, a bearing 15 is embedded and installed inside the lower end of the mounting frame 4, the upper end of the screw 16 is rotatably inserted into the bearing 15, a guide rod 21 is provided at the upper end of the bottom plate 6, a lifting platform 8 is provided between the mounting frames 4, a bearing plate 19 is provided above the lifting platform 8, a threaded block 17 and a sliding sleeve 20 are respectively provided at both ends of the lifting platform 8, the threaded block 17 is rotatably sleeved on the outer wall of the screw 16, the sliding sleeve 20 is slidably sleeved on the outer wall of the guide rod 21, and mounting plates 5 are provided at both ends of the mounting frame 4.

[0023] The implementation steps based on Example 1 are as follows: the circuit boards are stacked on the carrier plate 19, the motor 7 drives the screw 16 to rotate, and the lifting platform 8 is adjusted in height. When the uppermost circuit board fits with the suction cup 12, the suction force of the negative pressure pump 3 enters the inside of the diverter tube 1 through the suction tube 2, and then enters the inside of the installation box 9 through the two diverter tubes 14. The suction cup 12 is used on the circuit board to adsorb the circuit board. The circuit board located at the upper end of the installation box 9 is processed by electronic component mounting, and the circuit board located at the lower end of the installation box 9 is adsorbed and waits for transportation. After the circuit board is adsorbed, the lifting platform 8 is lowered by one end to ensure the rotation space of the installation box 9 and avoid the problem of wear of the clamping structure on the circuit board. Multiple suction nozzles effectively avoid the problem that the negative pressure inside the circuit board cannot effectively adsorb the circuit board due to the holes in the circuit board.

[0024] like Figure 1-Figure 5 As shown, compared with the first embodiment, the component mounting auxiliary tooling proposed by the utility model also includes: a ring gear 24 is sleeved on one end of the rotating shaft 25, a rotating bracket 11 is arranged on the upper end of the mounting frame 4, one end of the rotating shaft 25 is rotatably installed inside the rotating bracket 11, a motor 22 is arranged above the mounting frame 4, a gear 23 is arranged at the output end of the motor 22, the gear 23 and the ring gear 24 are meshed with each other, a protective cover 13 is arranged on one side of the rotating bracket 11, the motor 22, the gear 23 and the ring gear 24 are all located inside the protective cover 13, symmetrically distributed weighing sensors 18 are arranged on both sides of the lower end of the load-bearing plate 19 and the lower ends are connected to the lifting platform 8, and an alarm 10 is arranged on one side of the upper end of the mounting frame 4.

[0025] In this embodiment, the two shunt pipes 14 are equipped with separate pressure relief valves to regulate the suction force inside the upper and lower ends of the installation box 9. After the electronic components are mounted on the circuit board at the upper end, the pressure is replenished inside the corresponding suction cup 12 so that the circuit board can be taken out. Then the motor 22 drives the gear 23 to rotate, and the gear 23 pushes the gear ring 24, driving the rotating shaft 25 to rotate, and then driving the installation box 9 to rotate. The circuit board pre-adsorbed at the lower end of the installation box 9 is directly flipped upward for rapid loading. After loading, the operation of Example 1 is repeated, avoiding the cumbersome problem of frequent loading by workers, and improving the efficiency of electronic component mounting on the circuit board.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
